An inductively coupled oxygen radio-frequency (13.56 MHz) discharge is investigated based on modeling and experiment. Experimental measurement is done at a range of gas pressure of 1-30 mTorr, and rf power of 100-1000 W. We measure most of the important plasma parameters such as the densities of charged species, electron temperature, plasma potential, and electron energy distribution function. The measured values are compared with the results of the spatially averaged global model. We observe a generally good agreement between the modeling and the experiment. The scaling features, the transition of the operating region, and the radial distributions of charged species are also discussed.
The electron energy distribution function (EEDF) is measured with a Langmuir probe in an inductively coupled rf (13.56 MHz) Ar discharge in the pressure range from 5 to 70 mTorr, by changing the power injected into the plasma up to 100 W. The EEDFs measured at a pressure of 5 mTorr formed a bi-Maxwellian structure, which is not prominent due to high electron density, in the energy region lower than the lowest excitation threshold energy. The EEDF structure in the energy region higher than the threshold has a significant depletion of high energy electrons. The EEDF measured at a pressure higher than 10 mTorr can be approximated using a two-temperature distribution, which consists of the higher temperature in a low-energy region below the lowest excitation threshold and the lower temperature in a high-energy region. A global model using the two-temperature distribution is proposed and compared with the experimental results. The model consists of the rate equations for neutrals and charged particles and an energy-balance equation for electrons together with the balance equation for high-energy electrons. Pressure dependences of the electron density and temperatures predicted in this global model agree well with the experimental results except in the pressure range lower than 10 mTorr.
Thin films of In2Se3 deposited by thermal co-evaporation crystallize upon vacuum annealing almost single phase into an, up to now, unknown structure. Only when the films are capped with a thin oxide layer before annealing, the reportedly stable γ-In2Se3 structure, single phase and aligned along the c axis forms. Rutherford backscattering confirms an In to Se ratio of 2 to 3 for both structures. Nevertheless, the new structure has distinct x-ray diffraction peaks and Raman spectra. The new structure has a much lower resistivity than the γ-In2Se3 structure, consistent with its smaller electrical and optical energy gap. Both structures show large photoconductivity.
The present study extends our previous work that concerned the effective permittivities and absorptivities of particulate composites consisting of graphite-type microsphere inclusions in a dielectric matrix, and their suitability as radar-absorbing materials. Whereas in that work spheres of one size (radius a = 50 オm) had been considered only, we here study the dependence of the results on the sphere radius of up to one or several millimeters, and find sizable effects on permittivities for a1 mm, and below that for the absorptivities, indicating the increasing importance of multiple scattering effects. While the multiple-scattering formulas utilized here are based on a low-frequency approximation, we devise a modification of these formulas in order to extend their validity to higher frequencies (or larger particle sizes).
rsync-backup automates the process of backing up multiple systems to one or more backup servers. It focuses on making the process secure. It encrypts the backup going across the wire, only ships changed data, runs the server as root to preserve permissions and ownership, keeps people from seeing each other's backups, and doesn't require the server to trust any files sent from the clients. It doesn't ship password files, key files, nor other sensitive files across the wire, but backs them up locally instead. Admins may use one key for everyone (backups named after the client IP) or allow named backups (when a machine may change IP or when multiple independant backups may need to be made from one machine).

Pybliographer is a tool for managing bibliographic databases. It currently supports the following formats (reading and writing):
Pybliographer can be used for searching, editing, reformatting, etc. In fact, it's a simple framework that provides easy to use python classes and functions, and therefore can be extended to many uses (generating HTML pages according to bibliographic searches, etc).
In addition to the scripting environment, a graphical GNOME interface is available. It provides powerful editing capabilities, a nice hierarchical search mechanism, direct insertion of references into LyX (version 1.0.x), and more.Medicine-HOWTO より。使ってみようかな...

DHCPStatus is a Web-based query tool for browsing information stored in dhcpd's configuration and leases files. It correlates the subnet details that you configure in the conf file with the lease records that DHCPD maintains in its lease file. You can thus obtain an overall picture of your DHCP environment, as well as view details of individual leases for each IP. Changes: Support was added for pools defined outside subnet statements within shared networks in dhcpd.conf. License: GNU General Public License (GPL)

CVSSearch searches for code fragments using CVS comments. Specifically, it takes advantage of the fact that a CVS comment describes the lines of code involved in the commit and that this description will typically hold for many future versions. In other words, CVSSearch allows you to better search the most recent version of the code by looking at previous versions to better understand the current version. Changes: Konqueror is now supported. The homepage includes a KDE demo with 240 applications indexed. (Click 'Browse Database Contents' for the list.) Many bugs have been fixed, particularly in the GUI. You can now easily trace the origin of a line match by clicking the 'C' on its left to see the corresponding commit. CVSSearch should be quite usable now.
OCRE reads an image file and writes ascii characters. Changes: Accepting a black background and some internationalization.

Future microchips might manipulate light signals as easily as computer chips handle electronic data--only faster. That dream seems possible using photonic crystals--nanoscale periodic structures that can precisely control light propagation at specific wavelengths. In the 2 April PRL a team shows that another type of light-speed signal called a surface plasmon polariton (SPP) can be manipulated using the same principles. The researchers guided these electron waves along a gold surface with structures that are much easier to make than conventional photonic crystals. The new structures may also lead to new experiments aimed at better understanding SPPs, waves that consist of an unusual interaction between metallic electrons and light.( Sergey I. Bozhevolnyi et al., Phys. Rev. Lett. 86, 3008. )

Yabasic implements the most common and simple elements of the basic language. It comes with goto/gosub, with various loops, with user defined subroutines and libraries. Yabasic does monochrome line graphics and printing. Yabasic runs under Unix and Windows, it is small (around 200KB) and free. Changes: A fix for a bug from 2.690 which prevented yabasic from parsing simple expressions like a/(b), implementing logical shortcuts (i.e., conditions within if or while statements are only evaluated as far as needed), a new form of the open statement and function, no distinction between expressions and conditions any more, and a fix for a bug with printing under Windows.

This data structure features fast (O(log N)) insertion, removal, and retrieval of records, provided that there is a sorting relation over their keys and there are no entries with equal keys. The AVL tree is an explicit binary searching tree, where left children of each vertex are less or equal, while right children are greater or equal than the vertex itself. In addition, the tree is balanced so that the difference between the depths of the two subtrees of each vertex is at most one. Changes: Iterators work properly now, static library support has been added, and the Makefile has been cleaned up.
