Differentiated security in wireless mesh networks (2008)

The upcoming IEEE 802.11s standard enables easy establishment and maintenance of wireless mesh networks in residential and enterprise scenarios. They, however, need some special attention with respect to security. Due to multi-hop communication and routing on layer~2 in mesh networks, attacks on the routing, selective forwarding, and eavesdropping on confidential data become relatively easy. To avoid such attacks, we introduce differentiated security which is based on protection levels associated with nodes in the network. Participation in the MAC layer routing is facilitated according to the respective protection level of a node. Using additional cryptographic protection our approach can also avoid unintentional disclosure of confidential data.
Enhancing the heralded single photon rate from a silicon photonic chip by pump pulse interleaving (2015)

We demonstrate heralded single photon source on a silicon photonic chip by a pump interleaving technique. We have achieved 90±5% enhancement to single photon rate with only 14±2% reduction in quantum signal to noise ratio.
Studies towards the synthesis of the fluorescent bases of phenylalanine transfer ribonucleic acids: Synthesis of 7-(2-Hydroxy-3-methylbutyl)wye, a model for the minor base isolated from rat liver. (1989)

Treatment of 1-benzyl-7-(hydroxymethyl)wye (8) with PBr3 in the presence of Ph3P gave the phosphonium bromide 9 in good yield, Heating 9 and Me2 CHCHO (7) in MeOH in the presence of K2CO3 provided 1-benzyl-1, 4-dihydro-4, 7-dimethyl-6-(3-methyl-1-butenyl)-9H-imidazo[1, 2-a]purin-9-one (11), a positional isomer of the objective 1-benzyl-7-(3-methyl-1-butenyl)wye (5), as a major product. When the reaction was conducted in Me2NCHO at -65°C using n-BuLi as base, a 7 : 2 mixture of (E)-and (Z)-5 was obtained in good yield. Nevertheless, neither the protected amino aldehyde 18 nor 21 gave the desired olefin under similar conditions, implying poor applicability of this method to the synthesis of the fluorescent bases of phenylalanine transfer ribonucleic acids (tRNAsPhe).Compound 5 was alternatively synthesized by the Wittig reaction between 1-benzyl-7-formylwye (3) and Ph3P+CH2CHMe2 I- (4) in tetrahydrofuran as an equimolar mixture of the geometrical isomers in 50% yield. When the reaction was carried out in Me2SO at room temperature using two equivalents each of NaCH2SOMe and 4, the product, obtained in high yield, was (E)-11. The use of an equimolar amount of the base afforded (E)-5 in 26% yield. Oxidation of (E)-5 with OsO4 followed by hydrogenolysis over Pd-C gave 7-(2-hydroxy-3-methylbutyl)wye (2), a model for the minor base from rat liver tRNA.Phe.
Front-end sources of the LIL-LMJ fusion lasers: progress report and prospects (2003)

We give an up-to-date description of some present development issues, together with an architecture study and a systems engineering analysis, in the area of laser sources for the injection of the Laser Mega-Joule (LMJ), which are a part of the French ICF fusion program. After a brief description of the main concepts, the overview consists of two parts. The first one includes the standard first source (all-fiber design) that will be used for the activation of the facility of Ligne d'Integration Laser (LIL), the reduced-scale demonstrator under construction for the validation of the concepts and technology to be selected for the LMJ. The second one describes the state of the art in the prototyping of a new source, with extended performance with respect to optical noise and robustness, to be tested on LIL in a second step of the activation.
229m Th(3/2+, 3.5 eV) and a check of the exponentiality of the decay law (1998)

A new object is proposed for checking the exponentiality of the decay law of an isolated metastable state at long times — the anomalously low-lying level 3/2+ (3.5±0.5 eV) in 229Th. Highly efficient excitation of this level by laser radiation in combination with optimal collection of optical photons emitted in an isomeric transition make it possible to achieve measurement times longer than 50T 1/2.
Urinary adenylate kinase and urinary tract infections (1983)

Positive correlations were found among the appearance of adenylate kinase activity in the urine and the existence of bacteriuria, the Fairley test, and other criteria of urinary infection. Since the adenylate kinase isozymes of human tissues are organ specific and can be distinguished from one another, the appearance of adenylate kinase isozymes in urine was used in this study to identify the existence of infection in bladder or kidney. The findings suggest the usefulness of measuring the appearance of urinary adenylate kinase isozymes for the purpose of detection and differential diagnoses of urinary infections, particularly since adenylate kinase is absent or found in low concentrations in urine and serum under normal conditions.
Stereoscopic player and stereoscopic multiplexer: a computer-based system for stereoscopic video playback and recording (2005)

Computer-based solutions are well suited for capturing and playing stereoscopic video content at high quality, because the constraints of TV standards need not be obeyed. We developed an application called <i>Stereoscopic Player</i> to play stereoscopic videos. Based on Microsoft's DirectShow, it can handle all major video sources, codecs, stereoscopic layouts and viewing methods. Usability was an important goal in the application design; several features simplify handling of stereoscopic videos. To free the user from choosing the proper settings, we introduced the concept of stereoscopic information files and an Internet-based service for automatic configuration. The <i>Stereoscopic Multiplexer</i> is a solution to capture stereoscopic content within applications compatible with WDM capture drivers. It takes frames from two 'real' capture devices, synchronizes them and passes the resulting stereo pairs to the application. If the cameras support numerical control of camera parameters, Stereoscopic Multiplexer also synchronizes these parameters. Supporting resolutions up to high definition and a wide range of devices, Stereoscopic Multiplexer and Stereoscopic Player are universal, affordable solutions for stereoscopic video recording and playback.

Defining Candidate Oncogenes Leading to Increased Susceptibility to Leukemia in eed Mutant Mice. (2005)

Abstract We previously showed that loss of function of the chromatin regulator polycomb group gene (PcG) eed increases susceptibility to lymphoid tumour development (Sauvageau, M. et al. Blood 104 (11); 213). The human eed locus is in a region of chromosome 11 (11q14.2–22.3) which is associated with recurrent deletions in several reported cases of lymphoproliferative diseases. The persistant expression of the wild-type allele of eed is maintained in lymphomas developing in eed+/− animals. This suggests a haploinsufficient function for this gene in preventing tumorigenesis. We recently exploited an insertional mutagenesis screen to identify new cooperative leukemia-inducing genes in eed mutant mice. 325 retroviral insertion sites (RIS) representing 189 different gene loci have been identified by inverse-PCR from a total of 51 lymphomas (25 eed−/− and 26 wild-type). This screen revealed 18 gene loci known to be cancer related and 21 new common insertion sites (CIS) such as sh2d3c (n=4 tumours), fgfr3 (n=15 tumours) and myo5b (n=7 tumours). More than 97% of these CIS were common to both eed mutant and wild-type animals. We next assessed the expression levels of all the genes found in a 100 Kb region of genomic DNA surrounding the CIS identified in our screen in eed mutant and wild-type tumours as well as in the corresponding non-leukemic tissues. Almost 17% of the 48 genes analyzed, including fgfr2, fgfr3, ttc16 and adam15, are aberrantly expressed in non-transformed eed mutant cells when compared to wild-type controls (levels 5–100+ fold). Importantly, several of these genes are either aberrantly expressed in wild-type and eed mutant tumours or represent true CIS thus indicating their possible contribution to early tumour development in eed mutant mice. Moreover, our results do not incriminate eed as a modifier of gene expression once cells are fully transformed, since the oncogenic complement is similar in eed mutant and wild-type leukemias. Collectively, our results link the haploinsufficient role of eed to the appropriate regulation of genes involved in leukemia development.
Energy Efficient User Association, Resource Allocation and Caching Deployment in Fog Radio Access Networks (2021)

The heterogeneous fog radio access networks (Fog-RAN), the integration of fog computing, and traditional heterogeneous radio access networks can be implemented through the next-generation wireless communication networks. However, most of the solutions are limited to the spectrum efficiency optimization, and cross-tier interference existing in the fog access points (F-APs) could affect the network performance seriously. In this paper, the user association, resource allocation (including bandwidth and power), and caching deployment are investigated in the heterogeneous Fog-RAN to consider energy efficiency and cross-tier interference mitigation. Specifically, the user association, resource allocation, and caching strategy are formulated as a non-convex optimization problem and then transformed into a convex problem, which can be solved by a proposed algorithm based on the concept of the alternating direction method of multipliers (ADMM). Then an ADMM-based algorithm is proposed to enhance the energy efficiency of the Fog-RAN. Compared with the current solutions, simulation results illustrate the proposed algorithm’s convergence and effectiveness.
Formation of chalcogen containing plasmas and their use in the synthesis of photovoltaic absorbers (2005)

Chalcogen-containing plasmas were used to convert indium, copper–indium, and copper–indium–gallium films into their respective chalcogen-containing phases. An argon plasma was used to activate either hydrogen sulfide or elemental selenium vapor. The article describes the inductively coupled plasma setup and its characterization using optical emission spectroscopy. The kinetics of selenide/sulfide formation were examined as a function of time and temperature. The thin films were characterized using x-ray diffraction, optical transparency, and scanning electron microscopy. In all cases the use of the plasma dramatically enhanced chalcogen reactivity. Indium films were completely converted to β-In2S3 at 250°C by plasma processing, while no evidence of this phase was observed in films treated thermally at 350°C. The use of plasma enabled the complete conversion of Cu–In and Cu–In–Ga precursors to their ternary and quaternary chalcopyrite phases, respectively, at 350°C in less than 1h using chalcogen partial pressures <1Pa.
Reservoir characteristics and well-logging evaluation of the Lower Cambrian shales in southeast Chongqing, China (2016)

To accurately identify the reservoir characteristics and main controlling factors of the Cambrian Niutitang black shale in the southeast Chongqing, a series of systematic measurements were conducted on core samples from Well Yuke-1 and Well Youke-1. The measurements include clay mineral analysis, XRD analysis, petrophysical properties, specific surface area, pore diameter and TOC, as well as Ro and maceral compositions. The Niutitang shale reservoir contains detrital minerals and clay minerals averagely of 51.34% and 32.74%, respectively. The average effective porosity and permeability are 1.2% and 8.0×10-3mD, respectively, typically of ultra-low porosity and permeability. Mesopores are dominant, accounting for approximately 73% of the total pore volume. The average BET specific surface area is 7.75m2/g and the average pore diameter is 5.3nm. The average TOC is 2.29% and the average Ro is 3.12%, indicating that the organic matter is in over-maturity stage. Statistical analyses of the measurements show that the micropore volume is positively correlated with TOC but negatively correlated with the total content of clay minerals; the mesopore volume is positively correlated with TOC, the total content of clay minerals and the content of carbonate minerals; the macropore volume is positively correlated with TOC and the content of carbonate minerals, weakly positively correlated with the content of detrital minerals but negatively correlated with the total content of clay minerals. The porosity and TOC of the Niutitang shale are computed using the conventional well-logging method for the Yuke-1 and Youke-1 wells, and the porosities are quite consistent with the core analysis resultsr, but in the shallow reservoir that contains no oil and gas, the TOC exhibits no correlation with the core analysis results.
Implementation of Variable Structure of a Dual-Mode Switched Reluctance Motor by Using Asymmetric Half-Bridge Topology (2020)

This paper investigate a 12/10-pole Switched Reluctance Motor (SRM) which can be used as a six-phase or three-phase machine by altering the winding connection. The parameter relationship including resistance, inductance, phase current and torque between two operation modes is deduced and analyzed. A connection method between the machine and power converter based on three-phase asymmetrical half bridge (AHB) structure and the corresponding control strategy are proposed to carry out dual-mode operation. The inductance and torque characteristics of six-phase and three-phase operation are comparatively analyzed, and then the steady-state performances and mode-changing simulation are also performed. Finally, an experimental setup is developed and the independent steady-state operation and mode-changing experiment are implemented. Both the simulations and experiments validate the proposed mode-changing scheme.
Motion vector coding algorithm based on adaptive template matching (2010)

Motion estimation as well as the corresponding motion compensation is a core part of modern video coding standards, which highly improves the compression efficiency. On the other hand, motion information takes considerable portion of compressed bit stream, especially in low bit rate situation. In this paper, an efficient motion vector prediction algorithm is proposed to minimize the bits used for coding the motion information. First, a possible motion vector predictor (MVP) candidate set (CS) including several scaled spatial and temporal predictors is defined. To increase the diversity of predictors, the spatial predictor is adaptively changed based on current distribution of neighboring motion vectors. After that, adaptive template matching technique is applied to remove non-effective predictors from the CS so that the bits used for the MVP index can be significantly reduced. As the final MVP is chosen based on minimum motion vector difference criterion, a guessing strategy is further introduced so that in some situations the bits consumed by signaling the MVP index to the decoder can be totally omitted. The experimental results indicate that the proposed method can achieve an average bit rate reduction of 5.9% compared with the H.264 standard.
Machine Learning Approach for Identification of Objective Function in Production Scheduling Problems (2019)

Systems optimization techniques have become increasingly important in recent years. Experience and knowledge from human experts play a critical role in designing optimization tools for practical uses. These system's evaluation criteria should be selected to accurately reflect the intention of the human operators. In this paper, we propose a machine learning approach for the estimation of objective functions for production scheduling problems. We propose a method to identify the objective function of a problem consisting of the weighted sum of the completion time, the sum of the tardiness, the weighted number of tardy jobs, the maximum tardiness or the sum of setup costs. We consider a supervised learning scenario for predicting an objective function and evaluate several techniques, including a three layer neural network, random forest, and k-neighborhood method. We further investigate feature extraction methods to achieve higher identification accuracy. The effectiveness of the proposed method is verified by comparing the results with methods based on a simplified method that does not use machine learning.

An adaptive data predistorter for compensation of nonlinear distortion in OFDM systems (1997)

In this paper, an adaptive data predistortion technique which can compensate for the nonlinear effect of a TWT high-power amplifier (HPA) in orthogonal frequency-division multiplexing (OFDM) systems is proposed. It is shown that the convergence time and MSE of an adaptive data predistorter can be significantly reduced by using a broadcasting technique and by designing appropriate training signals.
Application of Serum Alpha Feto-Protein Assay in Mass Survey of Primary Carcinoma of Liver (1974)

The results of AFP screening by Ouchterlony double diffusion method and counter current electrophoresis in 343,999 persons for mass survey of primary liver cancer are presented. Through the observation that while AFP was positive, the results of other examinations were largely negative, and the appearance of obvious signs was found later than AFP screening, it is suggested that AFP screening has some significance in early detection of primary liver cancer. In endemic areas of primary liver cancer, repeated AFP screenings are recommended.
Fast, broad-range disinfection of bacteria, fungi, viruses and prions (2009)

Effective disinfectants are of key importance for the safe handling and reprocessing of surgical instruments. This study tested whether new formulations containing SDS, NaOH and 1-propanol (n-propanol) are simultaneously active against a broad range of pathogens including bacteria, fungi, non-enveloped viruses and prions. Inactivation and disinfection were examined in suspension and on carriers, using coagulated blood or brain homogenate as an organic contaminant. Coomassie blue staining was used to assess whether the formulations undesirably fixed proteins to rough surfaces. A mixture of 0.2 % SDS and 0.3 % NaOH in 20 % n-propanol achieved potent decontamination of steel carriers contaminated with PrP(TSE), the biochemical marker for prion infectivity, from 263K scrapie hamsters or from patients with sporadic or variant Creutzfeldt-Jakob disease. 263K scrapie infectivity on carriers was decreased by > or =5.5 logs. Furthermore, the formulation effectively inactivated poliovirus, hepatitis A virus and caliciviruses (including murine norovirus) in suspension tests. It also yielded significant titre reductions of bacteria (Enterococcus faecium, Mycobacterium avium; >6 logs), fungi (spores of Aspergillus niger; > or =5 logs) and poliovirus (>4 logs) embedded in coagulated blood on carriers. The formulation was not found to fix proteins more than was observed with water as the cleaning reagent. In conclusion, SDS, NaOH and n-propanol can synergistically achieve fast, broad-range disinfection.
Humoral and cell surface interactions during gamma-irradiation leukemogenesis in vitro. (1992)

Gamma-irradiation of plateau phase cultures of the clonal murine bone marrow stromal cell line D2XRII followed by cocultivation of a clonal interleukin 3 (IL-3) (granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent hematopoietic progenitor cell line FDC-P1JL26 results in a significant increase in "cobblestone islands" of attachment and emergence of subclonal factor-independent malignant sublines. Biochemical purification of conditioned medium from irradiated D2XRII cells yielded a 75,000-dalton glycoprotein termed leukemogenic stromal factor (LSF) that was neutralized by a polyclonal antiserum to murine macrophage colony-stimulating factor (M-CSF). A monoclonal antibody to the murine M-CSF receptor (c-fms) neutralized the biological activity of this molecule in a manner comparable to its effect on recombinant human or murine M-CSF. FDC-P1JL26 parent cells were positive for Ly5, MEL-14, mGR, VLA-4, PGP-1 (CD44), and Thy1.2. After culture in LSF, Thy1.2, MEL-14, and mGR became undetectable; however, significant cell surface MAC-1 antigen and c-fms (M-CSF receptor) were expressed. Neither line was positive for Ly6, Ly22, I-CAM-1, or B220 antigen. LSF-precultured FDC-P1JL26 cells transferred as single cells to microwell culture with 5000-cGy-irradiated D2XRII cells revealed a 60-fold increase in frequency of cobblestone island formation and evolution of factor-independent subclones compared to the parent line. Both parent and LSF-precultured cells became factor independent at a 100-fold lower frequency if kept in suspension in LSF in the absence of stromal cells. Antiserum to M-CSF or monoclonal antibody to the murine M-CSF receptor (c-fms) did not inhibit or displace cobblestone island formation by either clone of FDC-P1 on irradiated stromal cells indicating a mechanism of binding not involving the M-CSF receptor. However, anti-serum to the M-CSF receptor inhibited growth of one factor-independent subclone. In separate studies, a subclone of IL-3-dependent 32Dc13 cells, expressing the transfected murine c-fms protooncogene but not the parent 32Dc13 cell line or another subclone expressing the transfected gene for the human M-CSF receptor, showed adherence and became factor independent when cocultivated with irradiated D2XRII stromal cells. Thus, irradiated stromal cells bind M-CSF receptor-positive hematopoietic progenitor cells and induce c-fms-dependent factor-independent tumorigenic subclones. The cellular interactions in this model may be relevant to gamma-irradiation leukemogenesis in vivo.
Detection of the deep biosphere in metamorphic rocks from the Chinese continental scientific drilling (2021)

It is generally accepted that there is a vast, well-populated biosphere in the subsurface, but the depth limit of the terrestrial biosphere has yet to be determined, largely because of the lack of access to the subsurface. Here as part of the Chinese Continental Scientific Drilling (CCSD) project in eastern China, we acquired continuous rock cores and endeavored to probe the depth limit of the biosphere and the depth-dependent distribution of microorganisms at a geologically unique site, that is, a convergent plate boundary. Microbiological analyses of ultra-high-pressure metamorphic rock cores taken from the ground surface to 5,158-meter reveal that microbial distribution was continuous up to a depth of ~4,850 m, where temperature was estimated to be ~137°C. The metabolic state of these organisms at such great depth remains to be determined. Microbial abundance, ranging from 10<sup>3</sup> to 10<sup>8</sup> cells/g, was also related to porosity, but not to the depth and rock composition. In addition, microbial diversity systematically decreased with depth. Our results support the notion that temperature is a key factor in determining the lower limit of the biosphere in the continental subsurface.
