Efficient High-Rate Secret Key Extraction in Wireless Sensor Networks Using Collaboration (2014)

Secret key establishment is a fundamental requirement for private communication between two entities. In this article, we propose and evaluate a new approach for secret key extraction where multiple sensors collaborate in exchanging probe packets and collecting channel measurements. Essentially, measurements from multiple channels have a substantially higher differential entropy compared to the measurements from a single channel, thereby resulting in more randomness in the information source for key extraction, and this in turn produces stronger secret keys. We also explore the fundamental trade-off between the quadratic increase in the number of measurements of the channels due to multiple nodes per group versus a linear reduction in the sampling rate and a linear increase in the time gap between bidirectional measurements. To experimentally evaluate collaborative secret key extraction in wireless sensor networks, we first build a simple yet flexible testbed with multiple TelosB sensor nodes. Next, we perform large-scale experiments with different configurations of collaboration. Our experiments show that in comparison to the 1 × 1 configuration, collaboration among sensor nodes significantly increases the secret bit extraction per second, per probe, as well as per millijoule of transmission energy. In addition, we show that the collaborating nodes can improve the performance further when they exploit both space and frequency diversities.
Oligonucleotide based artificial nuclease (OBAN) systems. Bulge size dependence and positioning of catalytic group in cleavage of RNA-bulges (2003)

Three zinc ion dependent oligonucleotide based artificial nucleases (OBANs) have been synthesized. These consist of 2'-O-methyloligoribonucleosides connected to 5-amino-2,9-dimethylphenanthroline via a urea function to a linker extending either from C-5 of deoxyuridine or from the 2'-position of uridine moieties. Both types of linkers are placed centrally in the modified sequence and in addition one OBAN carries the C-5 modified dU as an additional nucleoside unit at the 5'-end. All three OBANs are shown to cleave target oligoribonucleotides selectively. The target RNA's are varied to form differently sized bulges (0-5 nucleotides (nt)) and the different OBANs have different preferences for which sizes are preferentially cleaved. The OBAN with the centrally positioned C-5 linked zinc chelate preferentially cleaves 3 and 4-nt bulges, the OBAN with the 2'-linked chelate has a preference for slightly smaller bulges and the OBAN with a 5'-end chelate is more efficient the larger the bulge is. In addition the OBAN with the centrally positioned C-5 linked zinc chelate is shown to be a real enzyme, capable of turnover of substrate and displaying Michaelis-Menten behaviour. The main differences in efficiency of cleavage between the different OBAN-RNA substrate combinations are likely to be due to proximity factors i.e. the positioning of a catalytic group relative to cleaved phosphodiester functions. The model systems investigated partially display the importance of catalytic group positioning and should be useful in future development of more efficient OBANs.
Patient Falls in Stroke Rehabilitation (1995)

Since falls are so frequent, they must be considered a significant problem in stroke rehabilitation. Fall prevention strategies should therefore be developed and included in rehabilitation programs.
Fast Optical Recordings of Membrane Potential Changes From Dendrites of Pyramidal Neurons (1999)

Understanding the biophysical properties of single neurons and how they process information is fundamental to understanding how the brain works. A technique that would allow recording of temporal and spatial dynamics of electrical activity in neuronal processes with adequate resolution would facilitate further research. Here, we report on the application of optical recording of membrane potential transients at many sites on neuronal processes of vertebrate neurons in brain slices using intracellular voltage-sensitive dyes. We obtained evidence that 1) loading the neurons with voltage-sensitive dye using patch electrodes is possible without contamination of the extracellular environment; 2) brain slices do not show any autofluorescence at the excitation/emission wavelengths used; 3) pharmacological effects of the dye were completely reversible; 4) the level of photodynamic damage already allows meaningful measurements and could be reduced further; 5) the sensitivity of the dye was comparable to that reported for invertebrate neurons; 6) the dye spread approximately 500 micron into distal processes within 2 h incubation period. This distance should increase with longer incubation; 7) the optically recorded action potential signals from basolateral dendrites (that are difficult or impossible to approach by patch electrodes) and apical dendrites show that both direct soma stimulation and synaptic stimulation triggered action potentials that originated near the soma. The spikes backpropagated into both basolateral dendrites and apical processes; the propagation was somewhat faster in the apical dendrites.
Characterization of <i>CEBPA</i> Mutations in Acute Myeloid Leukemia: Most Patients with <i>CEBPA</i> Mutations Have Biallelic Mutations and Show a Distinct Immunophenotype of the Leukemic Cells (2005)

These data revealed that most AML with CEBPA mutations were associated with an immunophenotype of HLA-DR(+)CD7(+)CD13(+)CD14(-)CD15(+)CD33(+)CD34(+). The close relationship of CEBPA mutations with the leukemia status of the patients and the concordance of mutation in presenting and relapse samples implicate the CEBPA mutation as a potential marker for monitoring minimal residue disease.
Enabling Pro-Active User-Centered Recommender Systems: An Initial Evaluation (2007)

Traditionally, an end-user has played only a pas- sive role when viewing commercial media: he/she is ex- pected to consume content, not interact with it. In this paper we explore advanced user interaction techniques in the home environment. One example of such ad- vanced interaction is the creation of micro-personalized recommendations: messages that can be used as a basis for social sharing of third-party content. We describe a system for the distributed creation of micro-personal recommendations in a consumer electronics setting and show initial user testing results.
Input dimension reduction in neural network training-case study in transient stability assessment of large systems (2002)

The problem in modeling large systems by artificial neural networks (ANN) is that the size of the input vector can become excessively large. This condition can potentially increase the likelihood of convergence problems for the training algorithm adopted. Besides, the memory requirement and the processing time also increase. This paper addresses the issue of ANN input dimension reduction. Two different methods are discussed and compared for efficiency and accuracy when applied to transient stability assessment.
Scalar Waving: Improving the Efficiency of SIMD Execution on GPUs (2014)

GPUs take advantage of uniformity in program control flow and utilize SIMD execution to obtain execution efficiency. In SIMD execution, threads are batched into SIMD groups to share a common program counter and execute identical instructions on SIMD pipelines. Previous research has shown that there is a significant number of scalar instructions - instructions where different threads in a SIMD group execute using the same input operands and generate the exact same output - present in a range of applications. GPUs eliminate redundant fetches and decodes by utilizing a shared common pipeline front-end. However, most GPUs do not handle scalar instruction efficiently, allowing these instructions to be redundantly executed by the threads in a SIMD group. In this paper, we propose to use scalar execution to eliminate redundant execution of scalar instructions. We introduce scalar waving as a mechanism to batch scalar operations possessing the same PC and execute them as a group on SIMD lanes for efficiency. We also propose simultaneous execution of dynamically-formed scalar waves with SIMD groups to overcome the under-utilization of SIMD lanes when encountering divergence. We evaluate our work using 22 different GPU benchmarks taken from 4 different benchmark suites. We evaluate a range of configurations using timing simulation. Our results show that scalar waving can obtain up to a 25% improvement in performance on average. Our experiments also provide insight into the amount of performance gain that we can expect with scalar waving as a function of the scalar content, occupancy, and memory characteristics of the target application.
<i>Pityrosporum</i> yeasts ‐ what's new? (1997)

The lipophilic yeast Pityrosporum ovale is a member of the normal human cutaneous flora in adults but also associated with several skin diseases. In pityriasis versicolor, under the influence of predisposing factors, P. ovale changes from the round blastospore form to the mycelial form. A great problem in pityriasis versicolor is the high rate of recurrence and to avoid this a prophylactic treatment is mandatory. Pityrosporum folliculitis is a chronic disease characterized by pruritic follicular papules and pustules located primarily on the upper trunk, neck and upper arms. In direct microscopy clusters of round budding yeast cells are found. The disease responds rapidly to antimycotic therapy. There are now many studies indicating that P. ovale plays an important role in seborrhoeic dermatitis. Many of these are treatment studies showing a good effect of antimycotics paralleled by a reduction in number of organisms. Severe seborrhoeic dermatitis often difficult to treat is associated with AIDS. In peripheral blood from a high number of patients with seborrhoeic dermatitis we found an increase in number of natural killer T-cells and decreased PHA and Con-A stimulation. Secondary we found low serum IgG antibody titres in patients compared to controls. Other studies have found a reduced lymphocyte stimulation reaction when lymphocytes from patients with seborrhoeic dermatitis were stimulated with a P. ovale extract. Additionally, IL-2 and IFN gamma production by lymphocytes from patients was markedly depressed and IL-10 synthesis were increased after stimulation with P. ovale extract. The majority of adult patients with atopic dermatitis localized to the head, neck and scalp are prick-test positive to a protein P. ovale extract. One study showed that p. ovale extracts increased IL-4, IL-10 and IgE synthesis in patients with atopic dermatitis. There are also treatment studies indicating that antifungal treatment may be beneficial in these patients.

The many faces of long noncoding <scp>RNA</scp>s (2014)

Over the past few years, the field of noncoding RNAs has grown from a niche for geneticists into a prominent domain of mainstream biology. Advances in genomic technologies have provided a more comprehensive view of the mammalian genome, improving our knowledge of regions of the genome devoid of protein-coding potential. A large body of evidence supports the proposal that noncoding RNAs account for a large proportion of the transcriptional output of any given cell and tissue type. This review will delve into the biogenesis and function of long noncoding RNAs. We will discuss our current understanding of these molecules as major chromatin players, and explore future directions in the field.
Functional Analysis of Paralogous Thiol-disulfide Oxidoreductases in Bacillus subtilis (1999)

The in vivo formation of disulfide bonds, which is critical for the stability and/or activity of many proteins, is catalyzed by thiol-disulfide oxidoreductases. In the present studies, we show that the Gram-positive eubacterium Bacillus subtilis contains three genes, denoted bdbA, bdbB, and bdbC, for thiol-disulfide oxidoreductases. Escherichia coli alkaline phosphatase, containing two disulfide bonds, was unstable when secreted by B. subtilis cells lacking BdbB or BdbC, and notably, the expression levels of bdbB and bdbC appeared to set a limit for the secretion of active alkaline phosphatase. Cells lacking BdbC also showed decreased stability of cell-associated forms of E. coli TEM-beta-lactamase, containing one disulfide bond. In contrast, BdbA was not required for the stability of alkaline phosphatase or beta-lactamase. Because BdbB and BdbC are typical membrane proteins, our findings suggest that they promote protein folding at the membrane-cell wall interface. Interestingly, pre-beta-lactamase processing to its mature form was stimulated in cells lacking BdbC, suggesting that the unfolded form of this precursor is a preferred substrate for signal peptidase. Surprisingly, cells lacking BdbC did not develop competence for DNA uptake, indicating the involvement of disulfide bond-containing proteins in this process. Unlike E. coli and yeast, none of the thiol-disulfide oxidoreductases of B. subtilis was required for growth in the presence of reducing agents. In conclusion, our observations indicate that BdbB and BdbC have a general role in disulfide bond formation, whereas BdbA may be dedicated to a specific process.

A boundary-fragment-model for object detection (2006)

Abstract. The objective of this work is the detection of object classes, such as airplanes or horses. Instead of using a model based on salient image fragments, we show that object class detection is also possible using only the object’s boundary. To this end, we develop a novel learning technique to extract class-discriminative boundary fragments. In addition to their shape, these “codebook ” entries also determine the object’s centroid (in the manner of Leibe et al. [19]). Boosting is used to select discriminative combinations of boundary fragments (weak detectors) to form a strong “Boundary-Fragment-Model ” (BFM) detector. The generative aspect of the model is used to determine an approximate segmentation. We demonstrate the following results: (i) the BFM detector is able to represent and detect object classes principally defined by their shape, rather than their appearance; and (ii) in comparison with other published results on several object classes (airplanes, cars-rear, cows) the BFM detector is able to exceed previous performances, and to achieve this with less supervision (such as the number of training images). 1
An investigation on parasitic couplings and feedback loops in the CMOS circuits (2003)

Two major problems in network partitioning are investigated: the parasitic coupling capacitances between the partitioned subcircuits, and the feedback loops. The coupling capacitance effect is shown to be negligible if state transitions in the neighboring subcircuits do not occur simultaneously. A decoupling criterion is developed to decide whether the coupling between the subcircuits is negligible. A loop-merging algorithm is developed to handle feedback in loops such a manner that the network topology is described by a unidirectional signal path graph, which makes it possible for a single-sweep Gauss-Seidel relaxation. Moreover, an event-driven algorithm is proposed to take advantage of the hierarchical loop structure resulting from the merge algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Evidence of Extensive Alternative Splicing in Post Mortem Human Brain HTT Transcription by mRNA Sequencing (2015)

Despite 20 years since its discovery, the gene responsible for Huntington's Disease, HTT, has still not had its function or transcriptional profile completely characterized. In response to a recent report by Ruzo et al. of several novel splice forms of HTT in human embryonic stem cell lines, we have analyzed a set of mRNA sequencing datasets from post mortem human brain from Huntington's disease, Parkinson's disease, and neurologically normal control subjects to evaluate support for previously observed and to identify novel splice patterns. A custom analysis pipeline produced supporting evidence for some of the results reported by two previous studies of alternative isoforms as well as identifying previously unreported splice patterns. All of the alternative splice patterns were of relatively low abundance compared to the canonical splice form.

Cement Proteins of the Tube-building Polychaete Phragmatopoma californica (2005)

The mineralized tube of the sandcastle worm Phragmatopoma californica is made from exogenous mineral particles (sand, shell, etc.) glued together with a cement secreted from the "building organ" on the thorax of the worm. The glue is a cross-linked mixture of three highly polar proteins. The complete sequences of Pc-1 (18 kDa) and Pc-2 (21 kDa) were deduced from cDNAs derived from previously reported peptide sequences (Waite, J. H., Jensen, R., and Morse, D. E. (1992) Biochemistry 31, 5733-5738). Both proteins are basic (pI approximately 10) and exhibit Gly-rich peptide repeats. The consensus repeats in Pc-1 and -2 are VGGYGYGGKK (15 times), and HPAVXHKALGGYG (eight times), respectively, in which X denotes an intervening nonrepeated sequence and Y is modified to 3,4-dihydroxyphenyl-l-alanine (Dopa). The third protein, Pc-3, was deduced from the cement to be about 80 mol % phosphoserine/serine, and the cDNA was obtained by exploiting the presence of poly-serine repeats. Pc-3 consists of a family of at least seven variants with 60-90 mol % serine most of which is phosphorylated in the cement. Pc-1, -2, and -3 contain cysteine some of which reacts to form 5-S-cysteinyl-Dopa cross-links during the setting process.
INVESTIGATION OF THE EFFECT OF AGGREGATE PRETREATMENT WITH ANTISTRIPPING AGENTS ON THE ASPHALT-AGGREGATE BOND (1997)

ABSTRACT Addition of Chemical antistripping agents (ASA)to asphalt has inherent disadvantages such as reduction of the effectiveness of ASA in hot asphalt and formation of relatively weak bond with the aggregate surface. To circumvent such problems, a novel approach of aggregate pretreatment with ASA was investigated in this study. The aggregate was pretreated with aqueous emulsions/solutions of different organic surface modifiers. The effectiveness of this aggregate pretreatment procedure was evaluated to ascertain the asphalt-aggregate bond strength using the boiling water test. Boiling water test was selected for its rapidity and simplicity. The
Lonidamine Extends Lifespan of Adult Caenorhabditis elegans by Increasing the Formation of Mitochondrial Reactive Oxygen Species (2011)

Compounds that delay aging in model organisms may be of significant interest to antiaging medicine, since these substances potentially provide pharmaceutical approaches to promote healthy lifespan in humans. The aim of the study was to test whether pharmaceutical concentrations of the glycolytic inhibitor lonidamine are capable of extending lifespan in a nematodal model organism for aging processes, the roundworm Caenorhabditis elegans. Several hundreds of adult C. elegans roundworms were maintained on agar plates and fed E. coli strain OP50 bacteria. Lonidamine was applied to test whether it may promote longevity by quantifying survival in the presence and absence of the compound. In addition, several biochemical and metabolic assays were performed with nematodes exposed to lonidamine. Lonidamine significantly extends both median and maximum lifespan of C. elegans when applied at a concentration of 5 micromolar by 8% each. Moreover, the compound increases paraquat stress resistance, and promotes mitochondrial respiration, culminating in increased formation of reactive oxygen species (ROS). Extension of lifespan requires activation of pmk-1, an orthologue of p38 MAP kinase, and is abolished by co-application of an antioxidant, indicating that increased ROS formation is required for the extension of lifespan by lonidamine. Consistent with the concept of mitohormesis, lonidamine is capable of promoting longevity in a pmk-1 sensitive manner by increasing formation of ROS.
