Malware class recognition using image processing techniques (2017)

Increasing suspicious instructions of various malware through a challenge to the malware analysts to identify and classify samples belongs to the malicious family. They have witnessed the very fast increase in both the number and complexity of malware set of instructions. Malware invest profoundly in technology and capability to reorganize the process of building and mutate existing malware set of instructions to avoid traditional protection. Classify malware variants by applying image processing techniques. The textures play an important role in many image processing applications. In this paper we proposed the Support Vector Machine (SVM) multi-class malware image classification challenge from an image processing perspective. The multi-resolution and wavelets are used to build effective texture feature vector using Gabor Wavelet, GIST and Discrete wavelet Transform and other features. The proposed algorithm experimented on Malimg Dataset of malware total 12,470 samples are used. In that 1610 samples are trained and 1710 samples are tested on 8 malware family which is randomly selected from the dataset. We compare this approach to existing malware classification approaches previously published research work. This is an efficient and more accurate malware detection algorithm using Wavelet Transform with machine learning classifiers techniques to detect malware samples more capably compare to existing work.
Angiogenic factors and pre-eclampsia: an early marker is needed (2008)

Pre-eclampsia, a pregnancy complication characterized by hypertension and proteinuria, is still a major cause of neonatal and maternal mortality, and acute and long-term morbidities for both mother and neonate. There is mounting evidence that an imbalance between angiogenic factors, such as VEGF (vascular endothelial growth factor) or PlGF (placental growth factor), and factors inhibiting angiogenesis, such as sFlt1 (soluble fms-like tyrosine kinase 1) and sEng (soluble endoglin), are closely related to the pathogenesis of pre-eclampsia. In the present issue of Clinical Science, Bills and co-workers report that VEGF(165)b, an alternative splice variant of the VEGF pre-mRNA, is up-regulated in women with normal pregnancy and that this increase was delayed or diminished in women who developed pre-eclampsia. Thus this protein could serve (alone or in combination with other parameters) as a new marker for risk assessment in terms of pre-eclampsia.
In vivo monitoring of cellular transplants by magnetic resonance imaging and positron emission tomography (2004)

Cellular loss is a common pathological observation in many disease conditions. Recent evidence that these cells can be replaced has generated huge excitement over possible clinical applications. The use of stem or progenitor cells, which can differentiate into site-appropriate phenotypes required to "repair" the damaged tissue, has already demonstrated potential in animal models, but many aspects of this novel treatment strategy require further elucidation. Most importantly, the monitoring of the safety of cellular transplants in patients remains a challenge. Traditional histological methods do not address the dynamic nature of transplant-induced recovery and highlight the necessity of in vivo imaging to probe the survival, migration and functional consequences of transplanted cells. This paper reviews how non-invasive imaging technology can be used to serially assess intact living organisms in order to visualise and monitor cellular transplants.
Super-fast parallel eigenface implementation on GPU for face recognition (2014)

Eigenface is one of the most common appearance based approaches for face recognition. Eigenfaces are the principal components which represent the training faces. Using Principal Component Analysis, each face is represented by very few parameters called weight vectors or feature vectors. While this makes testing process easy, it also includes cumbersome process of generating eigenspace and projecting every training image onto it to extract weight vectors. This approach works well with small set of images. As number of images to train increases, time taken for generating eigenspace and weight vectors also increases rapidly and it will not be feasible to recognize face in big data or perform real time video analysis. In this paper, we propose a super-fast parallel solution which harnesses the power of GPU and utilizes benefits of the thousands of cores to compute accurate match in fraction of second. We have implemented Parallel Eigenface, the first complete super-fast Parallel Eigenface implementation for face recognition, using CUDA on NVIDIA K20 GPU. Focus of the research has been to gain maximum performance by implementing highly optimized kernels for complete approach and utilizing available fastest library functions. We have used dataset of different size for training and noted very high increase in speedup. We are able to achieve highest 460X speed up for weight vectors generation of 1000 training images. We also get 73X speedup for overall training process on the same dataset. Speedup tends to increase with respect to training data, proving the scalability of solution. Results prove that our parallel implementation is best fit for various video analytics applications and real time face recognition. It also shows strong promise for excessive use of GPUs in face recognition systems.
Automatic Multi-Modal Meeting Camera Selection for Video-Conferences and Meeting Browsers (2007)

In a video-conference the participants usually see the video of the speaker. However if somebody reacts (e. g. nodding) the system should switch to his video. Current systems do not support this. We formulate this camera selection as a pattern recognition problem. Then we apply HMMs to learn this behaviour. Thus our system can easily be adapted to different meeting scenarios. Furthermore, while current systems stay on the speaker, our system will switch if somebody reacts. In an experimental section we show that -compared to a desired output -a current system shows the wrong camera more than half of the time (frame error rate 53%), where our system selects the wrong camera in only a quarter of the time (FER 27%).
Indole-3-acetic acid homeostasis in transgenic tobacco plants expressing the Agrobacterium rhizogenes rolB gene (1993)

The rolB gene of the plant pathogen Agrobacterium rhizogenes has an important role in the establishment of hairy root disease in infected plant tissues. When expressed as a single gene in transgenic plants the RolB protein gives rise to effects indicative of increased auxin activity. It has been reported that the RolB product is a β-glucosidase and proposed that the physiological and developmental alterations in transgenic plants expressing the rolB gene are the result of this enzyme hydrolysing bound auxins, in particular (indole-3-acetyl)-β-D-glucoside (IAGluc), and thereby bringing about an increase in the intracellular concentration of indole-3-acetic acid (IAA). Using tobacco plants as a test system, this proposal has been investigated in detail. Comparisons have been made between the RolB phenotype and that of IaaM/iaaH transformed plants overproducing IAA. In addition, the levels of IAA and IAA amide and IAA ester conjugates were determined in wild-type and transgenic 35S-rolB tobacco plants and metabolic studies were carried out with [13C6]IAA [2′-14C]IAA, [14C]IAGluc, [5-3H]-2-o-(indole-3-acetyl)-myo-inositol and [14C]indole-3-acetylaspartic acid. The data obtained demonstrate that expression of the rolB encoded protein in transgenic tobacco does not produce a phenotype that resembles that of IAA over producing plants, does not alter the size of the free IAA pool, has no significant effect on the rate of IAA metabolism, and, by implication, appears not to influence the overall rate of IAA biosynthesis. Furthermore, the in vivo hydrolysis of IAGluc, and that of the other IAA conjugates that were tested, is not affected. On the basis of these findings, it is concluded that the RolB phenotype is not the consequence of an increase in the size of the free IAA pool mediated by an enhanced rate of hydrolysis of IAA conjugates.

Prosthetic Ankle-Foot System That Adapts to Sloped Surfaces (2012)

The anatomical ankle is capable of providing adaptation to sloped surfaces, a function that is not available in most traditional lower limb prostheses. Commercial prostheses that are claimed to adapt to slopes are limited by high cost, delay in response, reduced stability, and loss of energy through damping. The purpose of the present work was to develop a prototypical prosthetic ankle unit that adapts to sloped surfaces and is sufficiently durable for short-term take-home trials. The prototype switches between low and high rotational impedances by means of a wrap spring clutch mechanism. The clutch is held in a disengaged position when unloaded and deflection of a compressible pylon under axial load rotates a control collar and engages the clutch. The prototype was subjected to 100,000 cycles of mechanical endurance testing based on ISO 10328 standards to determine the suitability for two-week take-home testing. Three persons with unilateral transtibial amputations were recruited to test the prototype in the laboratory, providing subjective feedback through a survey and participating in a motion analysis study to confirm the performance of the slope adaptation function. Translation of the ankle moment-angle curves for all subjects along the ankle angle axis demonstrated a change of the ankle alignment when subjects walked with the adaptable ankle on surfaces of different slopes. The ankle moment-angle curves had a lower slope than the subjects’ usual prostheses, and some subjects had distinct flat regions in the moment-angle curves when using the adaptable ankle. The arbors of the clutch demonstrated significant wear when tested to 100,000 cycles based on ISO 10328 standards, yet the adaptable ankle continued to hold testing loads. The alignment change observed for sloped surfaces suggests the prototype was providing slope adaptation. The flat regions on the ankle moment-angle curves suggest the clutch may have been slipping. Refinement of the clutch engagement mechanism and continued development to reduce the weight and size of the prototype is needed prior to take-home testing.
Local statin therapy differentially interferes with smooth muscle and endothelial cell proliferation and reduces neointima on a drug-eluting stent platform (2005)

As proof of principle, our study provides evidence that local application of a HMG-CoA reductase inhibitor on a drug-eluting stent platform can efficiently limit neointima formation. Consequently, these compounds warrant further clinical evaluation to confirm this finding. Our data further suggest that the anti-restenotic effect of local statin administration might be associated with a more protective interaction with the endothelium than that observed with compounds currently employed on drug-eluting stents.
Bronchospasm after inhalation of pancreatic dornase. (1968)

Aerosolized mucolytic agents are commonly used in the treatment of bronchopulmonary diseases in which tenacious mucopurulent secretions constitute a major factor in the pathologic process (1-3). Two such agents in widespread use are pancreatic dornase (Dornavac®) and acetylcysteine (Mucomist®). The following case report demonstrates a hitherto unreported complication, that of acute and lifethreatening bronchospasm related to the use of aerosolized pancreatic dornase.
HER‐2/<i>neu</i> is overexpressed infrequently in patients with prostate carcinoma (2002)

Unlike breast carcinoma and contrary to prior reports, HER-2 overexpression by IHC in archival prostate tissue from patients who eventually developed hormone-refractory disease was infrequent. There did not appear to be any correlation between HER-2 overexpression by IHC and shed HER-2 antigen levels in serum by ELISA in this tumor type. Whether trastuzumab possesses single-agent activity or modulates chemotherapy response in tumor types other than breast carcinoma remains to be determined.
Understanding the determinants of Australian hospital nurses' hand hygiene decisions following the implementation of a national hand hygiene initiative (2015)

Hand hygiene is the primary measure in hospitals to reduce the spread of infections, with nurses experiencing the greatest frequency of patient contact. The '5 critical moments' of hand hygiene initiative has been implemented in hospitals across Australia, accompanied by awareness-raising, staff training and auditing. The aim of this study was to understand the determinants of nurses' hand hygiene decisions, using an extension of a common health decision-making model, the theory of planned behaviour (TPB), to inform future health education strategies to increase compliance. Nurses from 50 Australian hospitals (n = 2378) completed standard TPB measures (attitude, subjective norm, perceived behavioural control [PBC], intention) and the extended variables of group norm, risk perceptions (susceptibility, severity) and knowledge (subjective, objective) at Time 1, while a sub-sample (n = 797) reported their hand hygiene behaviour 2 weeks later. Regression analyses identified subjective norm, PBC, group norm, subjective knowledge and risk susceptibility as the significant predictors of nurses' hand hygiene intentions, with intention and PBC predicting their compliance behaviour. Rather than targeting attitudes which are already very favourable among nurses, health education strategies should focus on normative influences and perceptions of control and risk in efforts to encourage hand hygiene adherence.
Optimal control of systems with resource constraints (2007)

In this paper optimal control of systems with constrained computation and communication resources is studied. The timing of real-time scheduling algorithms like rate monotonic scheduling and earliest deadline first scheduling is analyzed. It is shown that these scheduling algorithms lead to periodically varying sampling periods and time delays. Modeling of the resulting periodically time-varying systems is described and based on this, the design of a periodic linear quadratic regulator is presented. Applying the lifting technique, a time-invariant reformulation of the design problem is obtained. The regulator gains result from solving algebraic Riccati equations. To further improve control performance, a method which combines offline-scheduling and periodic control is proposed. The methods are illustrated by an example.
Construction of Novel Saccharomyces cerevisiae Strains for Bioethanol Active Dry Yeast (ADY) Production (2013)

The application of active dry yeast (ADY) in bioethanol production simplifies operation processes and reduces the risk of bacterial contamination. In the present study, we constructed a novel ADY strain with improved stress tolerance and ethanol fermentation performances under stressful conditions. The industrial Saccharomyces cerevisiae strain ZTW1 showed excellent properties and thus subjected to a modified whole-genome shuffling (WGS) process to improve its ethanol titer, proliferation capability, and multiple stress tolerance for ADY production. The best-performing mutant, Z3-86, was obtained after three rounds of WGS, producing 4.4% more ethanol and retaining 2.15-fold higher viability than ZTW1 after drying. Proteomics and physiological analyses indicated that the altered expression patterns of genes involved in protein metabolism, plasma membrane composition, trehalose metabolism, and oxidative responses contribute to the trait improvement of Z3-86. This work not only successfully developed a novel S. cerevisiae mutant for application in commercial bioethanol production, but also enriched the current understanding of how WGS improves the complex traits of microbes.
Development of Genomic Resources for a thraustochytrid Pathogen and Investigation of Temperature Influences on Gene Expression (2013)

Understanding how environmental changes influence the pathogenicity and virulence of infectious agents is critical for predicting epidemiological patterns of disease. Thraustochytrids, part of the larger taxonomic class Labyrinthulomycetes, contain several highly pathogenic species, including the hard clam pathogen quahog parasite unknown (QPX). QPX has been associated with large-scale mortality events along the northeastern coast of North America. Growth and physiology of QPX is temperature-dependent, and changes in local temperature profiles influence pathogenicity. In this study we characterize the partial genome of QPX and examine the influence of temperature on gene expression. Genes involved in several biological processes are differentially expressed upon temperature change, including those associated with altered growth and metabolism and virulence. The genomic and transcriptomic resources developed in this study provide a foundation for better understanding virulence, pathogenicity and life history of thraustochytrid pathogens.
Ketonic Decarboxylation Catalysed by Weak Bases and Its Application to an Optically Pure Substrate (2004)

Abstract Ketonic decarboxylation is a very old reaction that transforms two carboxylic acids into a ketone or a dicarboxylic acid into a cyclic ketone, in particular adipic acid into cyclopentanone. Herein it is reported that catalytic amounts of weak bases such as sodium carbonate can carry out this reaction selectively. This is in accordance with a mechanism involving decarboxylation and nucleophilic attack at a second carboxyl group. The reaction can be employed in asymmetric syntheses since the stereogenic centres in the β‐positions retain their stereochemistry. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
Comprehensive Antibody Epitope Mapping of the Nucleocapsid Protein of Severe Acute Respiratory Syndrome (SARS) Coronavirus: Insight into the Humoral Immunity of SARS (2005)

A New MWD Concept for Geological Positioning of Horizontal Wells (1995)

Abstract A key requirement in extended reach and horizontal drilling is to maintain the borehole trajectory within the productive interval. This is important for maximizing hydrocarbon recovery particularly when drilling thin beds and complexly folded and faulted reservoirs. The task, however, is often frustrated by uncertainty attached to the reservoir geology. This paper presents the conceptual ideas of an acoustic reference system for geological positioning of deviated and horizontal boreholes performed while drilling. The primary objective has been to extend the radial detection range from a few meters as of current geosteering tools up to at least 20 meters. By using acoustic reflection techniques, the borehole position is referenced to acoustic reflectors identifying critical stratigraphie bed boundaries or contacts. Theoretical analysis and experimental results, including cross well measurements with a full-scale prototype, demonstrate the feasibility of applying acoustic referencing for geosteering purposes.
A Novel Assay for Protein Phosphatase 2A (PP2A) Complexes In Vivo Reveals Differential Effects of Covalent Modifications on Different <i>Saccharomyces cerevisiae</i> PP2A Heterotrimers (2005)

Protein phosphatase 2A (PP2A) catalytic subunit can be covalently modified at its carboxy terminus by phosphorylation or carboxymethylation. Determining the effects of these covalent modifications on the relative amounts and functions of different PP2A heterotrimers is essential to understanding how these modifications regulate PP2A-controlled cellular processes. In this study we have validated and used a novel in vivo assay for assessing PP2A heterotrimer formation in Saccharomyces cerevisiae: the measurement of heterotrimer-dependent localization of green fluorescent protein-PP2A subunits. This assay relies on the fact that the correct cellular localization of PP2A requires that it be fully assembled. Thus, reduced localization would occur as the result of the inability to assemble a stable heterotrimer. Using this assay, we determined the effects of PP2A C-subunit phosphorylation mimic mutations and reduction or loss of PP2A methylation on the formation and localization of PP2A(B/Cdc55p) and PP2A(B'/Rts1p) heterotrimers. Collectively, our findings demonstrate that phosphorylation and methylation of the PP2A catalytic subunit can influence its function both by regulating the total amount of specific PP2A heterotrimers within a cell and by altering the relative proportions of PP2A(B/Cdc55p) and PP2A(B'/Rts1p) heterotrimers up to 10-fold. Thus, these posttranslational modifications allow flexible, yet highly coordinated, regulation of PP2A-dependent signaling pathways that in turn modulate cell growth and function.
