FreeBSDで科学技術計算を行おうとした場合、まず気になるのはコンパイラの性能です。 いろいろ考えてやれば、数値演算は速くなりますが、 何も考えなければパフォーマンスが非常に悪いことになりかねません。 どうすればパフォーマンスが よくなるかをいろいろ見てみます。
The characteristics of argon electron cyclotron resonance plasma discharged by 7.0, 8.0, and 9.4 GHz microwaves were investigated. Experiments were conducted in a fixed magnetic field. It was found that the electron temperatures Te exhibited a trend of Te7.0<Te8.0<Te9.4 (suffixes represent the discharge microwave frequencies).
This article presents an add-on secondary electron energy spectrometer for scanning electron microscopes (SEMs). The add-on unit fits on to the specimen stage of a conventional SEM, and the SEM is operated as normal. As an objective lens, the add-on unit improves the SEMs spatial resolution by around a factor of 4 at a primary beam energy of 1 keV. The add-on unit functions as a multichannel open-loop voltage contrast spectrometer by employing a bandpass deflector/filter unit whose pass energy is ramped with time. The unit is designed to deflect the secondary electrons while leaving the primary beam unaffected. Initial experimental results show that significant voltage and material contrast can be obtained. In a data acquisition time of 0.32 s, a minimum detectable voltage difference of around 54 mV was obtained. Regions of copper and brass that were indistinguishable via the normal secondary electron image, were distinguished with a signal to noise ratio of around 12 by using the add-on spectrometer.
A technique for the accurate determination of the surface potential US and its evolution during irradiation, is proposed. The technique is based on detecting both backscattered (BSE) and secondary electrons (SE) in a scanning electron microscope (SEM). The (BSE + SE) spectra are measured using a compact, highly sensitive electrostatic toroidal spectrometer (ETS), specially adapted for SEM applications. The use of an ETS analyzer set in a SEM for deducing the surface potential from (SE + BSE) spectra of electron irradiated insulators is introduced here. The surface potential is determined, either from the measured maximum energy of the secondary electron peak, or from its beginning. Various dielectric materials such as MgO, Al2O3, Y2O3, mica (potassium silicate aluminum), and Teflon were studied by this technique. Experimental investigations of the beam energy and current effects on the surface potential of bare insulators are reported. The change, due to this surface potential, in some physical quantities such as the amount of BSEs and the most probable energy of their spectral distribution is also studied. The results concerning coated and grounded insulators highlight the influence of the internal electric field on the BSEs energy distribution. An account of the various benefits of using the toroidal spectrometer in the surface potential measurement is also given.

We report on the complex dielectric tensor components of four chalcopyrite semiconductors in an optical energy range (1.4-5.2 eV, from 0.9 eV for CuInSe2) determined at room temperature by spectroscopic ellipsometry. Our results were obtained on single crystals of CuInSe2, CuGaSe2, CuInS2, and CuGaS2. Values of refractive indices n, extinction coefficients k, and normal-incidence reflectivity R in the two different polarizations are given and compared with earlier data where available. We analyze in detail the structures of the dielectric function observed in the studied energy region. Critical-point parameters of electronic transitions are obtained from a fitting of numerically calculated second-derivative spectra d^2e(w)/dw^2. Experimental energies and polarizations are discussed on the basis of published band-structure calculations.
ZnO typifies a class of materials that can be doped via native defects in only one way: either n type or p type. We explain this asymmetry in ZnO via a study of its intrinsic defect physics, including Zn_O, Zn_i, V_O, O_i, and V_Zn and n-type impurity dopants, Al and F. We find that Zn_O is n type at Zn-rich conditions. This is because (i) the Zn interstitial, Zn_i, is a shallow donor, supplying electrons; (ii) its formation enthalpy is low for both Zn-rich and O-rich conditions, so this defect is abundant; and (iii) the native defects that could compensate the n-type doping effect of Zn_i (interstitial O, Oi, and Zn vacancy, V_Zn), have high formation enthalpies for Zn-rich conditions, so these "electron killers" are not abundant. We find that Zn_O cannot be doped p type via native defects (O_i, V_Zn) despite the fact that they are shallow (i.e., supplying holes at room temperature). This is because at both Zn-rich and O-rich conditions, the defects that could compensate p-type doping (V_O, Zn_i, Zn_O) have low formation enthalpies so these "hole killers" form readily. Furthermore, we identify electron-hole radiative recombination at the V_O center as the source of the green luminescence. In contrast, a large structural relaxation of the same center upon double hole capture leads to slow electron-hole recombination (either radiative or nonradiative) responsible for the slow decay of photoconductivity.
The bonding and electronic structure of TiN thin films grown by sputtering have been characterized by means of resonant photoemission spectroscopy using synchrotron radiation. Specifically we found a complex resonance profile that exhibits a maximum at 45 eV followed by a second structure at 50 eV. The intensity enhancement observed at 45 and 50 eV is consistent with the resonant photoemission of the Ti 3d states involved in the valence band of TiN and the multiplet configuration of the [Ti 3p^5 3d^2]* excited states. The autoionizing character of the [Ti 3p^5 3d^2]* states could also be confirmed by observation of the corresponding autoionization emission. The resonance is used to determine the Ti 3d contribution to the valence band. The results are in good agreement with calculated Ti 3d partial density of states.
By means of scanning tunneling microscopy, the Si(313)12x1 surface has been found to be, after Si(111)7x7, another stable elemental semiconductor surface with a metallic nature. On the basis of the details revealed by the high resolution STM images, an atomically rough model consisting of trenches and a variety of building entities has been proposed for the surface structure for further investigation. The common features of major stable silicon surfaces as well as the similarities and differences between these surfaces and their germanium counterparts are discussed in the context of the driving forces behind the reconstruction of elemental semiconductor surfaces.
By means of scanning tunnel microscopy the surface morphology of reconstructed Au(001) surfaces has been studied after bombardment with 600 eV Ar ions as a function of dose, in the range of 10^13 to 10^16 ions/cm2, and the experimental results analyzed in the light of molecular dynamics simulations using a glue potential. At low dose (5x10^13 ions/cm^2) new defects, different from the commonly observed vacancy islands are reported. They appear as depressions 0.06 nm deep, with a characteristic width of 1.44 nm. Bombardment with similar doses of Pt(001) show the same general behavior. Molecular dynamics simulations with a realistic glue potential that reproduces the hexagonal-like Au(001) reconstruction, confirm that these depressions are in fact two-dimensional /3 dislocation dipoles originated by the relaxation of vacancy rows on the ridges of the topmost reconstructed layer. These two-dimensional dipoles are seen to dissociate into individual two-dimensional dislocations that display the characteristics of ordinary bulk dislocations, e.g. glide or climb. At higher doses (3x10^14 ions/cm^2), but well below a nominal removal of 1 monolayer, vacancy islands, one atomic spacing high, are seen to nucleate on these depressions. With increasing ion damage these vacancy islands become the dominant feature. For doses of about 10^15 ions/cm^2, other defects related to the reconstruction, such as perpendicular reconstruction domains and unreconstructed patches of (001) square symmetry, become visible.
CheckInstall keeps track of all files installed by a "make install" or equivalent, creates a Slackware or RPM package with those files, and adds it to the installed packages database, allowing for easy package removal or distribution.

Thokbook is a personal library system written in Perl. It is intended for medium-to-large individual collections (several thousand books). Using thokbook, you can add books via ISBN or EAN (usually via a barcode scanner of some kind), get MARC records from libraries (so you don't have to type in the information for the vast majority of your books), and create Web pages so you can list all your books or search them. You can also check books in and out and record who checked them out.日本語の本も OK なら魅力的かも...
freq is a script designed to generate reports and graphs from the lastlog. It can display a variety of information in a variety of ways. Changes: This release speeds things up, allows for the installer to be non-interactive, and has been verified to work with IRIX 6.5.11m.
The vaporization of condensed materials in contact with high-current discharge plasmas is considered. A kinetic numerical method named direct simulation Monte Carlo (DSMC) and analytical kinetic approaches based on the bimodal distribution function approximation are employed. The solution of the kinetic layer problem depends upon the velocity at the outer boundary of the kinetic layer which varies from very small, corresponding to the high-density plasma near the evaporated surface, up to the sound speed, corresponding to evaporation into vacuum. The heavy particles density and temperature at the kinetic and hydrodynamic layer interface were obtained by the analytical method while DSMC calculation makes it possible to obtain the evolution of the particle distribution function within the kinetic layer and the layer thickness.
A laser induced fluorescence technique (LIF) in combination with optical emission spectroscopy (OES) and Rayleigh scattering (RS) was applied to investigate absolute number densities of the population of the three nitrogen triplet states C^3Πu, B^3Πg, and the metastable A^3Σ u+ in an asymmetric low pressure rf discharge. Primary targets of this investigation were the three lowest vibrational levels (v = 0,1,2) of each triplet state and additionally v = 8 of A^3Σu+ which can be populated very efficiently in the plasma sheath. Calibration of LIF intensities to absolute densities of A^3Σu+ and B^3Πg has been realized by comparison with the signal of the RS experiment done in pure nitrogen gas. Calibration of C^3Πu which we could not detect by LIF but rather only by OES was achieved after comparing OES and LIF signals of the B^3Πg state. Excitation energies of the analyzed states range from 6 up to 11.5 eV and the measured number densities differ by about seven orders of magnitude from as much as 1012 cm?3 down to almost 105 cm?3. In addition to the interpretation of the results this article describes the used calibration methods which are partly based on a suggestion made by P. Bogen (Proceedings of the XVI International Conference on Phenomena in Ionized Gases, Invited Papers, edited by W. Botticher, H. Wenk, and E. Schultz-Gulde, Dusseldorf, 1983, pp. 164-173).
Methods to chemically passivate the surfaces of amorphous-carbon films (a-C) produced by dc magnetron sputtering were studied. The chemical composition of carbon surfaces produced via sputtering are dependent upon the environment to which the carbon is exposed immediately following deposition. When the sputtered film is vented to ambient conditions, free radicals produced at the surface during the deposition process are quenched by reaction with oxygen and/or water to form an oxidized, hydrophilic surface. If the sputtered carbon film is, however, exposed to a reactive gas prior to venting to ambient, the chemical nature of the resulting surface can be modified substantially. Specifically, a less highly oxidized and much more hydrophobic carbon surface is produced when the surface free radicals are quenched via either an addition reaction (demonstrated with a fluorinated olefin) or a hydrogen abstraction reaction (demonstrated with two alkyl amines). Chemical modification of amorphous-carbon films can also be accomplished by performing the sputtering in a reactive plasma formed from mixtures of argon with molecular hydrogen, amines, and perfluorocarbons. The elemental composition of these films, and the relative reactivity of the surfaces formed, were investigated via x-ray photoelectron spectroscopy and contact-angle goniometry, respectively. In the case of sputtering with a mixture of argon and hydrogen, increasing the hydrogen flow results in an increase in the amount of hydrogen incorporated into the carbon film and a decrease in the surface free energy. Sputtering in diethylamine produces an amorphous-carbon film into which nitrogen is incorporated. The free energies of the a-C:N surfaces produced in this process are similar to those of the a-C:H films. Sputtering in a fluorocarbon vapor results in the incorporation of fluorine into the film structure and the formation of very low free-energy surfaces. Increasing the concentration of the fluorocarbon in the sputtering plasma increases the amount of F incorporated into the film. At the highest fluorocarbon flow rates employed, a-C films were produced with stoichiometries and surface free energies comparable to those of bulk Teflon.
CvsGraph is a utility for generation of graphical representation of revisions and branches from a CVS/RCS repository. Changes: This is a major rewrite of a lot of code. CvsGraph reads the repository file directly, which enables the proper evaluation of the tree structure in the repository when revision numbers are not in order. Branches are compacted horizontally so that a tree with many branches doesn't take too much space. Branches with no revisions are shown. Branches and revisions which are not in sequence or do not start at 1.1 are properly plotted. Minor configure updates, implementation of imagemaps, an ability to generate HTML that allows linking in the form of imagemaps, changes to some configuration parameters, and an ability to add custom expansion string from the command-line using -[0-9]. The executable has become significantly larger because of table optimization in flex. You can disable the optimization in configure with '--disable-speed'. This will slow the execution, but reduce the size.
Changes: FreeBSD 4.2 support and several bugfixes.
ttf2pt1 converts TTF fonts (.ttf) into PostScript Type 1 fonts and metrics (.pfa, .pfb, .afm).

Debfoster can detect such "orphaned" dependencies and will clean them up. It can be used as a front-end to apt or standalone. Changes: This release has been internationalised (with a Dutch translation included), and complies to the latest version of the Debian FHS.
The xmlprocfs is a new filesystem to report the data reported by proc filesystem in XML format, so the applications can read it easily. There is not any other difference between xmlproc filesystem and proc filesystem. Only some files can generate XML data now. Changes: This release of xmlprocfs should be applied to linux-2.4.2, and includes a great deal of proc output function fomalizing in the kernel, as well as some bugfixes.
Starting from a continuum description, we study the non-equilibrium roughening of a thermal re-emission model for one and two spatial dimensions. Using standard analytical techniques, we map our problem to a generalized version of an earlier non-local KPZ (Kardar-Parisi-Zhang) model. In 2+1 dimensions, the values of the roughness and the dynamic exponents calculated from our theory go like $ \alpha \approx z \approx 1 $ and in 1+1 dimensions, the exponents resemble the KPZ values for low vapor pressure, supporting experimental results. Interestingly, Galilean invariance is maintained althrough.

g4u ("ghost for unix") is a bootfloppy that allows one to easily clone PC
harddisks by using FTP. This is often done to deploy a common setup on a
number of PCs. The floppy offers two functions: it uploads the compressed
image of a local harddisk to a FTP server, and then it can retrieve that
image via FTP, uncompress it, and write it back to disk. Network
configuration is fetched via DHCP. As the harddisk is processes as a image,
any filesystem and operating system can be deployed using g4u.
Changes: This is a maintenance release, with lots of doc updates.

Changes: Fixes for nasty bugs whereby the data connection timeout went off incorrectly, per-user chroot(), a banned anonymous email address list, PASV range restriction, minor performance enhancements, a vsftpd.conf.5 man page, and non-PAM local authentication.ふーむ。
ReiserFS has problems supporting NFS because 64 bits of information are required to find an object in the tree, and NFS expects to find an inode with just the inode number (32-bits long). The good news is the NFS file handle has enough room to store the extra information ReiserFS needs in order to find the file again later, and other kernel developers have written APIs to give the file system control over some of the file handle. By the time this article is out, there should be public patches to add proper NFS support to ReiserFS.ということらしい。
This document is intended to be the comprehensive guide to the installation, administration, maintenance, and use of the Bugzilla bug-tracking system.

It also automagically queries the right registry for all domains and most netblocks. Changes: Updated .at, .be, .cy, .cz, .ee, .gr, .il, .pl, .ro, .vi, and .nz ccTLDs, new -cz, -nicat, -norid, and -rotld nic handles, new Telstra IP allocations, and a fix for a fencepost error.
Apt-sources simplifies the task of finding the nearest APT servers. The server list can be either downloaded and parsed from Debian.org or read in from a local file via a command-line argument. The scoring of the servers is done using embedded Netselect source code for distance (hops) and latency. The user also has the option of testing the servers using embedded BING source code for bandwidth scoring. Other command-line arguments include saving top placing servers to a file for future scoring and distribution selection (stable, unstable, and testing). Changes: Apt-Sources v2.0 has been totally rewritten. It has rid itself of Netselect and Bing source code and all other external source code. It now benchmarks lists of Debian mirrors via FTP and generates a sources.list of the best servers.ふむむ。
Gnome Flow is a program written to calculate and visualize simple steady-state fluid flows. It uses the relaxation method, and can calculate flows past symmetric objects. Steady-state means that it calculates the flow at a given time, and that the physical parameters are constant in time. Changes: Object data can be loaded from graphic files of many formats. Timer driven pressure calculation was added. Online help was updated.

It supports multiple simultaneous displays, and can attach/detach each display on the fly.ううむ(^^;
abcde is a frontend to cdparanoia, wget, cd-discid, id3, and your favorite Ogg/MP3 encoder (Oggenc is the default). It grabs an entire CD and converts each track to Ogg/MP3, then comments or ID3-tags each file, all with one command. It supports parallelization, SMP, HTTP proxies, customizable filename organization and munging, playlist generation, and remote distributed encoding via distmp3. Changes: Defaults to FreeDB, new VAOUTPUTFORMAT variable, OpenBSD compatibility, new distmp3 scheduler, xingmp3enc support, new -C option, better Ogg commenting, and documentation updates.
Changes: This release fixes a tag/item centering bug in both menubox.c and checklist.c, a cosmetic bug in menubox.c where the cursor got left in the menu box when it first came up, and this release now includes a prefix variable to the Makefile for installing into a binary package build area.
ircGraph is a Perl script that connects to an IRC server to get statistics via the /lusers command. It then puts the stats in an RRD (Round Robin Database) file and generates graphics about the server and the IRC network using RRDTool. It was created to help ircadmins visualize and understand the traffic on their ircservers and in the IRC network. Changes: Creation of stats about the number of servers connected to an IRC network, replacement of the Makefile way of creating graphics by a new Perl script (makegraph.pl), moving the make db command into ircgraph -i, and both scripts have some more error checking.

Ghemical is a molecular modelling software package with a GUI (one for the GLUT library and another for GNOME) and some nice 3D-visualization tools. It can do all-atoms molecular mechanics and dynamics, athough the current parameter set is still experimental. It can also be used as a graphical front-end for the quantum chemistry program MPQC. Ghemical is written in C++, and hopefully offers a good framework for a generic freeware molecular modelling tool.
Changes: Binaries are now available for most Uni*es and Windows, as well as complete documentation. The new option --pargs sets program arguments on the command line, and the new option --dargs specifies additional debugger arguments. The startup time for big programs has significantly improved. Support for preferences was added, with many user-configurable options. Scrolling the assembly window outside of displayed range is now possible. The Data window can now be separated from the main window. The Memory View now handles editing in non-Hex mode, and it is also can display data in ASCII and another format at the same time. The window settings are now remembered from one session to another. The new command line option --editor-window provides much better integration with external editors. A graphical list of processes is now displayed when attaching to a process. The option to view memory at the address of a given variable is now available in the data and source editor contextual menus, and the option to print a dereferenced variable was added to the source editor contextual menu.

linuxdoc-make is a bunch of directories, Makefiles, and SGML example bundled together to allow you to create several output formats with just one make command. Localization is taken into account. Changes: This release now allows use of m4, and Makefile building is no longer recursive.DocBook 用ではないのね。
hc-cron is a cron daemon for 'home computers'. It runs specified jobs at periodic intervals and will remember the time when it was shut down and catch up jobs that have occurred during down time when it is started again. Hc-cron is based on the widely used vixie-cron and uses the same crontab format so that it can be used as a drop-in replacement for that program. Changes: This release adds a fix for a buffer overflow with long usernames, and other minor bugfixes
noflushd is a simple daemon that monitors disk activity, spins down disks whose idle time exceeds a certain timeout, and stops writes to them in order to keep them spun down as long as possible. It's mainly used on laptops to save power, but can also be useful to desktop users with noisy hard disks. noflushd requires a kernel thread named kupdate which is present in Linux kernel version 2.2.11 and later. For earlier kernels, bdflush version 1.6 provides equal functionality. Changes: Handling of timeout lists was fixed. The installation location of the init script was corrected. Verbose spindown messages were re-introduced. The name change of kupdate to kupdated in kernel versions 2.4.2-ac15 and 2.4.3pre3 is now honored.
Changes: A Macintosh port, and a couple of minor bugfixes.

adsl.sh is a Bash script to easily manage an ADSL pptp connection (most French "France Telecom" ADSL equipment uses this). It's pre-configured for this kind of connection, but you can easily edit the script to make it suit your needs. It can also update your IP adress on dhs.org and/or dyndns.org, and gracefully restart Apache (if you use VirtualHosts, it's mandatory when IP changes). Changes: Checking if your IP adress has changed, and if it didn't, it doesn't try to update dhs or dyndns, confirmation of a successful update, checking if the Virtual Hosts really work after an update, and if not, it keeps gracefully restarting Apache, considering a connection established as soon as an IP is given even if pppd doesn't say "Login OK" in the logs, and code cleanups.

A measuring apparatus based on a phase shifting interferometry technique to determine the mechanical properties of metal oxide films was presented. Thin films were prepared by ion-beam sputter deposition at low substrate temperature. Quantitative determination of the mechanical properties such as the internal stress, biaxial elastic modulus, and thermal expansion coefficient of metal oxide films were investigated. A phase shifting Twyman萌reen interferometer with the phase reduction algorithm was setup to measure the temperature-dependent stress in thin films. Two types of circular glass plates, with known Young's moduli, Poisson's ratios, and thermal expansion coefficients, were used as coating substrate. The temperature-dependent stress behavior of the metal oxide films was obtained by heating samples in the range from room temperature to 70 −C. The stresses of thin films deposited on two different substrates were plotted against the stress measurement temperature, showing a linear dependence. Four oxide films were reported for their film stresses and thermal expansion coefficients.
The 3ω method has been proven to be very useful for determining the thermal conductivity of thin films and their substrates. Several simplifications are often used in determining the thermal conductivity of the films based on the experimentally measured 3ω signal. These simplifications, however, have limited range of applicability. In this work, we present a detailed analysis and mathematical modeling of the 3ω method applied for different experimental conditions. Effects considered include the finite substrate thickness, anisotropic nature of the film and substrate thermal conductivity, the film-substrate thermal property contrasts, the effect of heat capacitance of the heater, and the effect of thermal boundary resistance. Several experimental results are analyzed using the models presented. This work shows that the 3ω method can be extended to a wide range of sample conditions, with anisotropic conductivities in both the substrate and the film, and with small film-substrate conductivity contrast.
nslint is a lint-like program that checks DNS files for errors. DNS or Domain Name System generally maps names to IP addresses and E-mail addresses in a hierarchical fashion.

The electric field in a low-pressure electrodeless discharge has been determined from discharge voltage measurements at constant discharge current as a function of gas pressure. Measurements have been made in neon, argon, and xenon at discharge currents of 1, 3, and 10 A with a driving frequency of 0.45 MHz. The behavior of the electric field as a function of gas pressure has been found to be qualitatively similar for all three gases. At the lowest gas pressures at which a discharge can be sustained, the electric field is relatively high. With increasing gas pressure the field reaches a local minimum, followed by a local maximum and another local minimum. Above 1 Torr, the electric field increases monotonically with gas pressure.
A three-dimensional simulation code which calculates wave propagation, plasma transport, and gas phase chemical reactions self-consistently in an electron cyclotron resonance plasma reactor has been developed. The code is designed to treat the three-dimensional inhomogeneity with a reasonable accuracy in a realistic configuration of the reactor within an acceptable computational time using common computer resources. The profiles of electromagnetic wave fields and the temporal evolution of plasma parameters and radical densities in a bounded, inhomogeneous, cylindrical system have been calculated. The code can resolve azimuthal asymmetry of the plasma associated with a rectangular waveguide coupling or an asymmetric injection of reactive gases as well as the radial and axial variations.
Although superhardness effects have been extensively investigated for epitaxial ceramic nanomultilayer films with the same crystal structures in the last decade, those for multilayers with different crystal structures have been seldom studied. In this article, NbN/TaN nanomultilayers have been designed and deposited by reactive magnetron sputtering. The results showed that the crystal structures of NbN and TaN are face-centered cubic and hexagonal in superlattice films, respectively, and the lattice plane (111) of NbN is coherent with the (110) of TaN, i.e., {111}fcc-NbN{110}h-TaN. The results of microhardness measurement showed that the superhardness effects of NbN/TaN multilayers exist in a wide range of modulation period from 2.3 to 17.0 nm. This phenomenon is different from that of epitaxial ceramic multilayers where the maximum hardness usually takes place at a modulation period of 5.0?10.0 nm. It is proposed that the coherent stresses and the structural barriers (fcc/hexagonal) to dislocation motion between NbN and TaN layers are the main reasons for the high-hardness value in a wide range of modulation periods.
Thin film coolers can provide large cooling power densities compared to bulk thermoelectrics due to the close spacing of hot and cold junctions. Important parameters in the design of such coolers are investigated theoretically and experimentally. A three-dimensional (3D) finite element simulator (ANSYS) is used to model self-consistently thermal and electrical properties of a complete device structure. The dominant three-dimensional thermal and electrical spreading resistances acquired from the 3D simulation are also used in a one-dimensional model (MATLAB) to obtain faster, less rigorous results. Heat conduction, Joule heating, thermoelectric and thermionic cooling are included in these models as well as nonideal effects such as contact resistance, finite thermal resistance of the substrate and the heat sink, and heat generation in the wire bonds. Simulations exhibit good agreement with experimental results from InGaAsP-based thin film thermionic emission coolers which have demonstrated maximum cooling of 1.15 ℃ at room temperature. With the nonideal effects minimized, simulations predict that single stage thin film coolers can provide up to 20-30 ℃ degrees centigrade cooling with cooling power densities of several 1000 W/cm^2.
Enormously high secondary electron emission yields under electric field are observed from MgO deposited on carbon nanotubes. The yields reach a value as high as 15 000 and are strongly dependent upon the bias voltage applied to the sample. The creation of the electric field across the MgO film after bombardment of primary electrons is considered as one of key features, since positive charges are generated at the surface by departure of secondary electrons. Subsequent bombarding electrons produce other secondary electrons inside the MgO film, then the liberated secondaries are accelerated towards the surface under the strong field. Under this condition, the secondary electrons gain sufficient energy to create further electrons by impact ionization. The process continues until an equilibrium avalanche is established. To elucidate the earlier explanations, the kinetic energy spectra of secondary electrons are measured by an energy analyzer at various bias voltages in MgO/carbon nanotube samples. The analysis of spectral results with the energy band diagram gives us strong evidence for the suggested mechanism.
Carbon nitride films with β-C3N4 crystals of 200 nm grain size were grown on Si (100) substrates using magnetron sputtering. Reactive deposition was achieved using a graphite target in an argon/nitrogen plasma at room temperature. These films were characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), x-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FTIR), and Raman spectroscopy. Micro level β-C3N4 crystal grains were observed with TEM. According to calculations from electron diffraction pattern, these crystalline structures were in a good agreement with hypothetical b-C3N4 structure. AFM measurement also indicated the grain size was around 200 nm and the carbon nitride films had low surface roughness. From XPS data, maximum N/C ratio of 0.5 was achieved in the films. XPS spectra of the films typically showed three peaks in the C 1s core level spectrum (centered at 284.6, 285.9, and 287.2 eV) and two peaks in the N 1s core level spectrum (centered at 398.7 and 400.2 eV). This indicates that there are two types of C-N bonds; N is bonded to sp2- or sp3-coordinated C atoms in the as-deposited films. FTIR spectra showed three absorption bands in the range of 1000?3000 cm?1. The absorption band around 2367 cm?1 can be attributed to CN nitrile bond. The absorption bands around 1559 and 1201 cm?1 demonstrate the existence of CN (sp2) and C?N (sp3) bonds. Analysis of Raman spectrum further demonstrated the coexistence of sp, sp2, and sp3 bonds. All of XPS, FTIR, and Raman measurements showed the presence of fourfold coordinated β-C3N4 crystals in the films, which is in good agreement with TEM and electron diffraction results.
iMolecular dynamics simulations are performed to study the fundamental role of the ion beam in determining the in-plane texture of 100 oriented (out-of-plane) MgO films during ion beam assisted deposition (IBAD). Sputter yields are determined as a function of in-plane orientation for Ar ion beams. The minimum sputter yield exists at an ion beam orientation corresponding to the MgO 110 direction. The finite width of the sputter yield minimum is attributable to two main factors: (i) only a fraction of the incident ions are oriented to travel directly down the center of the channel and (ii) ions that are not exactly parallel to the channeling direction may channel. While the simulations imply that it is possible to in-plane orient {001} MgO films using IBAD, there are fundamental limitations on the degree of ordering that can be achieved.

A fast ion penetrating a solid creates a track of excitations. This can produce displacements seen as an etched track, a process initially used to detect energetic particles but now used to alter materials. From the seminal papers by Fleischer et al. [Phys. Rev. 156, 353 (1967)] to the present [C. Trautmann, S. Klaumunzer and H. Trinkaus, Phys. Rev. Lett. 85, 3648 (2000)], `Coulomb explosion' and thermal spike models are treated as conflicting models for describing ion track effects. Here molecular dynamics simulations of electronic-sputtering, a surface manifestation of ion track formation, show that `Coulomb explosion' produces a `heat' spike so that these are early and late aspects of the same process. Therefore, differences in scaling are due to the use of incomplete spike models.

If there's an outbreak of the flu in your city, you can count on the Centers for Disease Control for help, but if it's the "I Love You" bug, forget it. That's because viruses spread differently on the internet than they do in the real world, according to a paper in the 2 April PRL. While a biological disease can only spread from person to person, a digital virus can reach many computers simultaneously from a single server. This difference in transmission makes computer viruses all but impossible to eliminate, according to the authors, but the model they describe may lead to better strategies for protecting the electronic world.(R. Pastor-Satorras and A. Vespignani, Phys. Rev. Lett. 86, 3200. )
