Learning invariants to illumination changes typical of indoor environments: Application to image color correction (2007)

Abstract This paper presents a new approach for automatic image color correction, based on statistical learning. The method both parameterizes color independently of illumination and corrects color for changes of illumination. This is useful in many image processing applications, such as image segmentation or background subtraction. The motivation for using a learning approach is to deal with changes of lighting typical of indoor environments such as home and office. The method is based on learning color invariants using a modified multi‐layer perceptron (MLP). The MLP is odd‐layered. The middle layer includes two neurons which estimate two color invariants and one input neuron which takes in the luminance desired in output of the MLP. The advantage of the modified MLP over a classical MLP is better performance and the estimation of invariants to illumination. The trained modified MLP can be applied using look‐up tables, yielding very fast processing. Results illustrate the approach and compare it with other color correction approaches from the literature. © 2007 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 17, 132–142, 2007
Secure Blind Decryption. (2011)

Abstract. In this work we construct public key encryption schemes that admit a protocol for blindly decrypting ciphertexts. In a blind decryp-tion protocol, a user with a ciphertext interacts with a secret keyholder such that the user obtains the decryption of the ciphertext and the key-holder learns nothing about what it decrypted. While we are not the first to consider this problem, previous works provided only weak secu-rity guarantees against malicious users. We provide, to our knowledge, the first practical blind decryption schemes that are secure under a strong CCA security definition. We prove our construction secure in the stan-dard model under simple, well-studied assumptions in bilinear groups. To motivate the usefulness of this primitive we discuss several applica-tions including privacy-preserving distributed file systems and Oblivious Transfer schemes that admit public contribution. 1
Multi-feature extraction method based on Gaussian pyramid and weighted voting for hyperspectral image classification (2021)

In this paper, a multi-scale feature extraction and classification method for hyperspectral images(HSI) based on Gaussian pyramid and weighted voting is proposed. Specifically, first, the HSI is decomposed into several Gaussian pyramids to extract multi-scale features, and then the matrix of spectral angle distance (mSAD) is used to generate weight coefficients to evaluate each feature. Finally, the weighted voting is used to obtain the final classification result. By integrating multiple features, the classification accuracy is significantly improved. The superiority of the proposed method is proved by experiments.
Three <i>Yersinia pestis</i> Adhesins Facilitate Yop Delivery to Eukaryotic Cells and Contribute to Plague Virulence (2010)

To establish a successful infection, Yersinia pestis requires the delivery of cytotoxic Yops to host cells. Yops inhibit phagocytosis, block cytokine responses, and induce apoptosis of macrophages. The Y. pestis adhesin Ail facilitates Yop translocation and is required for full virulence in mice. To determine the contributions of other adhesins to Yop delivery, we deleted five known adhesins of Y. pestis. In addition to Ail, plasminogen activator (Pla) and pH 6 antigen (Psa) could mediate Yop translocation to host cells. The contribution of each adhesin to binding and Yop delivery was dependent upon the growth conditions. When cells were pregrown at 28°C and pH 7, the order of importance for adhesins in cell binding and cytotoxicity was Ail > Pla > Psa. Y. pestis grown at 37°C and pH 7 had equal contributions from Ail and Pla but an undetectable role for Psa. At 37°C and pH 6, both Ail and Psa contributed to binding and Yop delivery, while Pla contributed minimally. Pla-mediated Yop translocation was independent of protease activity. Of the three single mutants, the Δail mutant was the most defective in mouse virulence. The expression level of ail was also the highest of the three adhesins in infected mouse tissues. Compared to an ail mutant, additional deletion of psaA (encoding Psa) led to a 130,000-fold increase in the 50% lethal dose for mice relative to that of the KIM5 parental strain. Our results indicate that in addition to Ail, Pla and Psa can serve as environmentally specific adhesins to facilitate Yop secretion, a critical virulence function of Y. pestis.
Activated Leukocyte Cell Adhesion Molecule (ALCAM) is associated with suppression of breast cancer cells invasion. (2006)

Analysis of ALCAM expression in relation to other molecular biomarkers revealed that ALCAM expression and the ALCAM/MMP-2 ratio are more promising indicators of breast cancer progression than MMP-2, E-cadherin, and alpha-catenin. Low ALCAM concentration correlated with an aggressive tumor phenotype, which supports the view that this adhesion molecule is a tumor suppressor marker with prognostic significance.
Satellite selection for multi-constellation (2008)

There will be 70~90 navigation satellites operating at the same time when Glonass and Galileo reach full operation capability. As a result, the number of visible satellites can reach 30. Thus the positioning accuracy will be improved greatly. However, so many satellite measurements may burden the receiverpsilas processing element when to use them to find a solution and to do integrity monitoring. Satellite selection can decrease the number of measurements and as a result can shorten the computing time. ldquoDoes satellite selection be still needed for multi-constellation?rdquo At first, this paper analyses the amount of calculation of least square estimation techniques to calculate user position with different number of measurements. The results show that reducing the number of measurements can cut the amount of calculation greatly. Then the relationship between GDOP and the volume of polyhedron formed by the ends of unit user-to-satellite vectors is analyzed. We found that the relationship when the number of satellites is more than 4 is different with that when the number of satellites equals 4. Therefore the relationship when the number of satellites is more than 4 is researched in detail and a fast satellite selection method is proposed. The main idea is selecting a subset whose geometry is most similar to the optimal subset among all the visible satellites. The simulation tests prove that the fast satellite selection method can reduce the number of required subsets to look up the optimal geometry greatly and the increased GDOP is relatively small. Meanwhile, this method can not only be applicable for multi-constellation, but also for single constellation.
Investigation of Power Supplies for a Piezoelectric Brake Actuator in Aircrafts (2006)

In order to facilitate the use of a piezoelectric brake actuator for direct drive applications in airplanes, a power supply system in the power range of several kW is developed, characterised by a high power density, high dynamic and low weight. It feeds the mechanical vibration and reactive power to a multi-mass ultrasonic motor. This contribution puts focus on the power supply and control architecture of the underlying PIBRAC project, whose objective is to study, design and test a novel type of piezoelectric brake actuator and its control electronics. The yield should be pronounced cuts in total weight and peak power demand, when compared to electromagnetic brake actuators
A high speed high jitter tolerant clock and data recovery circuit using crystal based dual PLL (2002)

The author describes a clock and data recovery circuit (CDRC) designed as the key function in an interface integrated circuit to support a fiber-optic local area network-the fiber distributed data interface (FDDI). A crystal-based dual PLL (phase-locked loop) locks to 125 Mb/s NRZI (nonreturn to zero inverted on ones) data and captures them. The jitter tolerance is 6.1 ns (8 ns bit period) to a random input data stream. The ECL-TTL and serial to parallel conversions are performed. This circuit operates at a single 5-V supply and dissipates 0.7 W. The CDRC was injected with a 6.1 ns peak-to-peak timing jitter at the random data input and still received FDDI data properly with BER(bit error rate) <2.5*10/sup -10/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Monoclonal antibody isolation of type II pneumocytes (1987)

A monoclonal antibody that identifies a membrane molecule unique in rat lung for type II alveolar epithelial cells was used to isolate these cells from enzymatically dispersed lung cells by fluorescence-activated cell sorting. Although multistep physical separation techniques have permitted the isolation of large quantities of these cells and flow cytometry has been used by others to isolate lamellar body-containing cells, the application of this antibody-directed sorting has distinct advantages. Because the marker molecule is expressed on immature type II cells prior to the development of lamellar bodies, the antibody will also permit their isolation and study.
Resources for developing algorithms and processing Level 1A and geolocation information (2002)

Every satellite data system starts with some form of Level 1 and geolocation processing. This paper provides information to help future missions better estimate the personnel, schedule, and computing requirements for their data processing and algorithm development. The level of development effort and the computational resources for Level 1A and geolocation processing for the MODIS instrument are described. This information is related to the requirements for the Level 1A and geolocation tasks. Estimates of how both development and processing resource requirements scale to these functional requirements are provided.
Learning to Link Entities with Knowledge Base (2010)

This paper address the problem of entity linking. Specifically, given an entity mentioned in unstructured texts, the task is to link this entity with an entry stored in the existing knowledge base. This is an important task for information extraction. It can serve as a convenient gateway to encyclopedic information, and can greatly improve the web users ’ experience. Previous learning based solutions mainly focus on classification framework. However, it’s more suitable to consider it as a ranking problem. In this paper, we propose a learning to rank algorithm for entity linking. It effectively utilizes the relationship information among the candidates when ranking. The experiment results on the TAC 20091 dataset demonstrate the effectiveness of our proposed framework. The proposed method achieves 18.5% improvement in terms of accuracy over the classification models for those entities which have corresponding entries in the Knowledge Base. The overall performance of the system is also better than that of the state-of-the-art methods. Base. Wikipedia is an online encyclopedia, and now it becomes one of the largest repositories of encyclopedic knowledge. In this paper, we use Wikipedia as our Knowledge Base. Entity linking can be used to automatically augment text with links, which serve as a convenient gateway to encyclopedic information, and can greatly improve user experience. For example, Figure 1 shows news from BBC.com. When a user is interested in ”Thierry Henry”, he can acquire more detailed information by linking ”Thierry Henry ” to the corresponding entry in the Knowledge Base. 1

Modeling of alpha-particle-induced soft error rate in DRAM (1999)

Alpha-particle-induced soft error in 256 M DRAM was numerically investigated. A unified model for alpha-particle-induced charge collection and a soft-error-rate simulator (SERS) was developed. We investigated the soft error rate of 256 M DRAM and identified the bit-bar mode as one of dominant modes for soft error. In addition, for the first time, it was found that trench-oxide depth has a significant influence on soft error rate, and it should be determined by the tradeoff between soft error rate and cell-to-cell isolation characteristics.

Total body water and the exchangeable hydrogen. II. A review of comparative data from animals based on isotope dilution and desiccation, with a report of new data from the rat (1977)

Total body water (TBW) determination by tritium space could be factitiously elevated by exchangeable H+ contained within water-soluble chemical configurations. Should this nonaqueous (molecular) exchangeable H+ turn out to be a large fraction of total exchangeable H+, TBW measurement by tritiated water (THO) dilution would display a systematic upward and non-random error. TBW was measured by THO dilution and subsequently by total body desiccation in 21 rats (weight 227+/-83 g, mean+/-SD). TBW was 71.38+/-2.4% by THO dilution and 70.20+/-1.5% by body desiccation. Analysis of variance of TBW vs. body weight showed a highly significant correlation both with desiccation (P less than 0.0005, r=-0.78) and dilution (P less than 0.03, r= -0.50). Convariance analysis of both methods showed no difference in slope (P greater than 0.9). There was a difference in variance (P less than 0.001) and means (P less than 0.03). Tritium space is 1.2% of body weight larger than TBW measured by desiccation. TBW measured by THO dilution gives a 1.71% overestimation of TBW as measured by desiccation. TBW measurement by THO dilution is accurate within less than 2% error. These findings have particular significance in the light of our theoretical model of the total nonaqueous exchangeable H+ in fat, protein, and carbodhydrate in the living vertebrate.
Doppler shift compensation techniques for LEO satellite on-board receivers (2012)

In this paper two techniques employed for compensating the Doppler shift encountered in LEO satellite receivers are presented. These include the analog compensation technique involving the carrier tracking loop and the compressive receiver technique. The compressive receiver technique which involves precise detection of the rapidly time varying carrier frequency received by the satellite receiver is discussed in further detail. A compressive receiver with a center frequency of 100 kHz and a Doppler shift up to ±100 kHz is simulated on MATLAB to test the technique.
Targeted therapies in epithelial ovarian cancer: Molecular mechanisms of action (2010)

Ovarian cancer is the leading cause of death in women with gynecological cancer. Most patients are diagnosed at an advanced stage and have a poor prognosis. Currently, surgical tumor debulking, followed by platinum- and taxane-based chemotherapy is the standard treatment for advanced ovarian cancer. However, these patients are at great risk of recurrence and emerging drug resistance. Therefore, novel treatment strategies are required to improve outcomes for women with advanced ovarian cancer. A variety of molecular targeted agents, the majority of which are monoclonal antibodies and small-molecule protein-kinase inhibitors, have been explored in the management of ovarian cancer. The targets of these agents include angiogenesis, the human epidermal growth factor receptor family, ubiquitin-proteasome pathway, epigenetic modulators, poly(ADP-ribose) polymerase (PARP), and mammalian target of rapamycin (mTOR) signaling pathway, which are aberrant in tumor tissue. The antiangiogenic agent, bevacizumab, has been reported as the most effective targeted agent and should be included in the standard chemotherapeutic regimen for advanced ovarian cancer. PARP inhibitors, which are mainly used in breast and ovarian cancer susceptibility gene-mutated patients, and mTOR inhibitors are also attractive treatment strategies, either alone or combination with chemotherapy, for ovarian cancer. Understanding the tumor molecular biology and identification of predictive biomarkers are essential steps for selection of the best treatment strategies. This article reviews the molecular mechanisms of the most promising targeted agents that are under early phase clinical evaluation for ovarian cancer.

Firearms and Violent Crime in New South Wales, 1995-2005 (2006)

This paper describes trends in the recorded incidence of firearm offences between 1995 and 2005 in New South Wales (NSW). The data presented here are an update of the trends in firearm offences reported in Crime and Justice Bulletin Number 57, 'Firearms and violent crime in New South Wales', which covered the period 1995 to 2000. The current analysis shows that the use of firearms in robbery offences peaked in 1997 and has since been steadily falling. Shooting offences have also declined in recent years after a peak in 2001. The rate of shooting incidents per 100,000 population is higher in Sydney than in the rest of NSW, with Fairfield-Liverpool Statistical Subdivision recording particularly high rates. The age profile of alleged offenders involved in firearms incidents has changed since 2000, with markedly fewer offenders aged 15-19 identified in connection with firearm-related incidents in 2005.
A Unified Reconfigurable CORDIC Processor for Floating-Point Arithmetic (2018)

This paper presents a unified reconfigurable coordinate rotation digital computer (CORDIC) processor for floating-point arithmetic. It can be configured to operate in multi-mode to achieve a variety of operations and replaces multiple single-mode CORDIC processors. A reconfigurable pipeline-parallel mixed architecture is proposed to adapt different operations, which maximizes the sharing of common hardware circuit and achieves the area-delay-efficiency. Compared with previous unified floating-point CORDIC processors, the consumption of hardware resources is greatly reduced. As a proof of concept, we apply it to 1638416384 points target Synthetic Aperture Radar (SAR) imaging system, which is implemented on Xilinx XC7VX690T FPGA platform. The maximum relative error of each phase function between hardware and software computation and the corresponding SAR imaging result can meet the accuracy index requirements.
Transformation of Rapeseed (Brassica napus L.) Plants with Sense and Antisense Constructs of the Fatty Acid Elongase Gene (2006)

The biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. One of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-CoA synthase (KCS) that is the key enzyme in erucic acid biosynthesis. This enzyme is involved in producing eicosanoeic (C20:1) and erucic acids (C22:1) from C18 fatty acids, and is encoded by the fatty acid elongase (FAE) gene. Specific primers were used to amplify the FAE gene and its promoter from genomic DNA by using PCR technique. The putative gene and its promoter were cloned in sense and antisense orientation into the plant expression vector (pBI121). The sense and antisense constructs of the FAE gene were transformed via Agrobacterium-mediated transformation into low erucic acid rapeseed (LEAR such as PF) and high erucic acid cultivars (HEAR such as Maplus). The transformed plants were screened on kanamycin-containing media and then analysed by PCR and Southern blotting techniques. Moreover, erucic acid content of the first  generation of transgenic (T0) plants analysed with gas chromatography, showed significant changes in fatty acid composition of transgenic rapeseed plants containing sense and antisense constructs of the FAE gene.
DETERMINATION OF INTRACELLULAR ADENOSINE TRIPHOSPHATE FOR DETECTING ANTI-HLA ANTIBODY-MEDIATED CYTOLYSIS (1980)

Intracellular adenosine triphosphate (ATP) determination appears to be a rapid, and reliable technique for the detection of complement-dependent cytolysis mediated by cytotoxic anti-HLA sera. Only a few minutes after the addition of complement to anti-HLA-coated target lymphocytes, a striking loss of intracellular ATP is observed. The technique can be easily performed with minute amounts of cells, serum, and complement, and exactly following the technical conditions of the standard HLA typing microcytotoxicity test (MCT). One of its main advantages over MCT is that the reading of results can be performed automatically. Since in most tissue typing laboratories all steps preceding the reading of MCT results have already been automated, this method could be of great interest, with a view to permitting the complete automation of HLA typing.
