A novel and versatile modeling of powerline channel (2009)

The paper introduces a novel method for modeling Powerline channels. The methodology is based on the use of three conductor transmission line. The mutual component of the three conductor line is varied to embrace the effects of multipath and impedance mismatches in the powerline is iteratively factored into the model by comparing with the measured frequency response of the powerline channel, without having any prior knowledge about them. In this way, the measured frequency response of the channel is finally reached. The method results in a versatile model that can be used for various studies like Electromagnetic Compatibility, Performance analysis and so on. The paper also suggests various ways of improving the precision of the prescribed method.
Medical Synonym Extraction with Concept Space Models (2015)

In this paper, we present a novel approach for medical synonym extraction. We aim to integrate the term embedding with the medical domain knowledge for healthcare applications. One advantage of our method is that it is very scalable. Experiments on a dataset with more than 1M term pairs show that the proposed approach outperforms the baseline approaches by a large margin.
Latent Replay for Real-Time Continual Learning (2020)

Training deep neural networks at the edge on light computational devices, embedded systems and robotic platforms is nowadays very challenging. Continual learning techniques, where complex models are incrementally trained on small batches of new data, can make the learning problem tractable even for CPU-only embedded devices enabling remarkable levels of adaptiveness and autonomy. However, a number of practical problems need to be solved: catastrophic forgetting before anything else. In this paper we introduce an original technique named "Latent Replay" where, instead of storing a portion of past data in the input space, we store activations volumes at some intermediate layer. This can significantly reduce the computation and storage required by native rehearsal. To keep the representation stable and the stored activations valid we propose to slow-down learning at all the layers below the latent replay one, leaving the layers above free to learn at full pace. In our experiments we show that Latent Replay, combined with existing continual learning techniques, achieves state-of-the-art performance on complex video benchmarks such as CORe50 NICv2 (with nearly 400 small and highly non-i.i.d. batches) and OpenLORIS. Finally, we demonstrate the feasibility of nearly real-time continual learning on the edge through the deployment of the proposed technique on a smartphone device.
The <i> <scp>UNC-112</scp> </i> Gene in <i>Caenorhabditis elegans</i>Encodes a Novel Component of Cell–Matrix Adhesion Structures Required for Integrin Localization in the Muscle Cell Membrane (2000)

Embryos homozygous for mutations in the unc-52, pat-2, pat-3, and unc-112 genes of C. elegans exhibit a similar Pat phenotype. Myosin and actin are not organized into sarcomeres in the body wall muscle cells of these mutants, and dense body and M-line components fail to assemble. The unc-52 (perlecan), pat-2 (alpha-integrin), and pat-3 (beta-integrin) genes encode ECM or transmembrane proteins found at the cell-matrix adhesion sites of both dense bodies and M-lines. This study describes the identification of the unc-112 gene product, a novel, membrane-associated, intracellular protein that colocalizes with integrin at cell-matrix adhesion complexes. The 720-amino acid UNC-112 protein is homologous to Mig-2, a human protein of unknown function. These two proteins share a region of homology with talin and members of the FERM superfamily of proteins. We have determined that a functional UNC-112::GFP fusion protein colocalizes with PAT-3/beta-integrin in both adult and embryonic body wall muscle. We also have determined that UNC-112 is required to organize PAT-3/beta-integrin after it is integrated into the basal cell membrane, but is not required to organize UNC-52/perlecan in the basement membrane, nor for DEB-1/vinculin to localize with PAT-3/beta-integrin. Furthermore, UNC-112 requires the presence of UNC-52/perlecan and PAT-3/beta-integrin, but not DEB-1/vinculin to become localized to the muscle cell membrane.
Recognition of human motion behaviors using multiple omni-directional vision sensors (2002)

In order to obtain flexibility of recognition system of human motion behaviors, omni-directional vision sensors are used for both tracking humans and getting multiple. views of different directions that allows human to move with natural behavior in large area. First, a vision-based aspect model is proposed which realize the recognition independent of the human-direction. It contains feature vector sequences that were taken from all direction around the human. Next, the authors' appearance-based feature extraction method is demonstrated to be useful for whole body motion recognition. A new technique, spatio-temporal continuous dynamic programming, allows a human to rotate even when he is doing a motion behavior.
p53 Down-Regulates CHK1 through p21 and the Retinoblastoma Protein (2001)

Both fission yeast and mammalian cells require the function of the checkpoint kinase CHK1 for G2 arrest after DNA damage. The tumor suppressor p53, a well-studied stress response factor, has also been shown to play a role in DNA damage G2 arrest, although in a manner that is probably independent of CHK1. p53, however, can be phosphorylated and regulated by both CHK1 as well as another checkpoint kinase, hCds1 (also called CHK2). It was therefore of interest to determine whether reciprocally, p53 affects either CHK1 or CHK2. We found that induction of p53 either by diverse stress signals or ectopically using a tetracycline-regulated promoter causes a marked reduction in CHK1 protein levels. CHK1 downregulation by p53 occurs as a result of reduced CHK1 RNA accumulation, indicating that repression occurs at the level of transcription. Repression of CHK1 by p53 requires p21, since p21 alone is sufficient for this to occur and cells lacking p21 cannot downregulate CHK1. Interestingly, pRB is also required for CHK1 downregulation, suggesting the possible involvement of E2F-dependent transcription in the regulation of CHK1. Our results identify a new repression target of p53 and suggest that p53 and CHK1 play interdependent and complementary roles in regulating both the arrest and resumption of G2 after DNA damage.
6-Phenylazocholestane derivatives: reassignment of the structures of products from phenylhydrazine and ozonised cholesterol derivatives (1967)

The reaction of phenylhydrazine with ozonised cholesteryl acetate has been reported to yield a product in which ring B is expanded to an eight-membered ring. This structure is shown to be incorrect, the true structure being 3β-acetoxy-6α-phenylazocholestan-5α-ol. Comparisons are made with related reactions in the carbohydrate field.
A new naphthaquinone antibiotic from a new species of yeast. (1984)

A fusiform yeast producing limited pseudomycelium and limited true mycelium on malt extract agar has been isolated. This non-fermentative yeast has hyaline cell walls but produces a thick, black oily exudate which is water insoluble and gives the colony a smooth black lacquered appearance. On the basis of morphology and physiology, this organism is distinctive enough to warrant the designation of a new genus. During stationary phase of cultures on chemically defined medium, a deep red substance is produced which has strong antibiotic activity against Staphylococcus aureus in vitro. The substance has been identified as a new natural naphthaquinone of the empirical formula C16H16O7 .
Adult stem cell differentiation: what does it mean? (2003)

The very property that puts adult stem cells in high demand, their ability to differentiate into mature cells with specialized functions, is a barrier to their expansion in culture. In many cases, tissue cell differentiation programs conclude with terminal division arrest and, eventually, cell death. Therefore, propagation and expansion of many types of normal mature cells in sufficient quantities for therapeutic applications is impractical. A method to expand adult somatic stem cells (SSCs), which are programmed for indefinite division, would provide a solution to this problem. After expanding SSCs to the quantities required, subsequent cell differentiation could yield large numbers of needed mature functional cells. A general approach is described for clonal expansion of adult SSCs. The method is based on suppression of asymmetric cell kinetics ("SACK"), a strategy that limits stem cell differentiation. As a first proof of principle, the SACK method was recently used to derive hepatic stem cells from adult rat liver. In addition to providing a potential method for routine expansion of adult SSCs from diverse mammalian tissues, the success of these initial studies elucidates the nature of "stem cell differentiation" in vitro and in vivo.
Characteristics of platelet aggregation induced by the monoclonal antibody ALB<sub>6</sub> (acute lymphoblastic leukemia antigen p 24) (1983)

The leukemia-associated cell surface antigen p 24 is found on normal platelets as well as on Bernard Soulier syndrome and thrombasthenia type I platelets. ALB6 IgG (a monoclonal antibody against p 24) induces the aggregation of platelets from normal donors but not from thrombasthenia. In contrast, ALB6 Fab inhibits platelet aggregation induced by collagen, ADP, thrombin, ionophore A 23187 and ALB6 IgG. The results suggest that ALB6 interferes with a mechanism common to all aggregation pathways; the possible mechanisms are discussed.
Low power design flow based on Unified Power Format and Synopsys tool chain (2013)

Unified Power Format (UPF) is an industry wide power format specification to implement low power techniques in a design flow. UPF is designed to reflect the power intent of a design at a relatively high level. UPF scripts help describe power intent such as: which power rails to be routed to individual blocks, when blocks are expected to be powered up or shut down, how voltage levels should be shifted between two different power domains, and type of measures taken for retention registers and memory cells contents if the primary power supply to a domain is removed, hence helping the design to be more efficient. With power becoming an important factor in today's electronic systems, there is a need for a more systematic approach to reduce power in complex designs; and UPF is developed to address this need. We have developed the complete UPF based low power design flow from high level behavioral description to physical layout. The design flow is accompanied by an example-driven and self-study tutorial suitable for hands-on teaching. The examples cover a variety of low power methods such as clock-gating, multi-voltage, power gating, and the combination of multi-voltage and power gating. This design flow is implemented using Synopsys electronic design automation tools and tested on Synopsys generic 90nm and 32/28nm libraries. The synthesis scripts are setup in `tcl' format that are compatible with the Synopsys synthesis and physical design tools.
Beyond Tamoxifen (2001)

Although tamoxifen appears to markedly reduce breast cancer risk in women with a prior diagnosis of atypical hyperplasia or in situ carcinoma, it is not clear what other groups of women receive substantial benefit. Major breast chemoprevention priorities are to (1) develop new agents that (a) have fewer side effects, (b) are effective in ER--as well as tamoxifen-resistant precancerous tissue, and (c) are compatible with hormone therapy; and (2) develop efficient clinical strategies including prognostic and predictive morphologic and molecular biomarkers. Breast tissue may be repeatedly sampled for evidence of intraepithelial neoplasia by fine needle aspiration, ductal lavage, or needle biopsy to select candidates at highest short-term risk as well as to monitor response in small proof of principle studies prior to a large cancer incidence trial. Molecular marker expression may also be used to select a cohort most likely to respond to a particular agent. A large number of new agents are attractive as potential prevention agents and some are already in clinical prevention testing. Compounds which should be effective in ER + precancerous tissue but may have a better side-effect profile include new selective estrogen receptor modulators which lack uterine estrogen agonist activity, isoflavones, aromatase inactivators/inhibitors for postmenopausal women, and gonadotropin-releasing hormone regimens for premenopausal women. Retinoids, rexinoids, and deltanoids may be efficacious in ER+ tissue resistant to tamoxifen. Agents which should theoretically have activity in ER- or ER+ precancerous tissue include polyamine synthesis inhibitors, tyrosine kinase inhibitors, combined demethylating agents and histone deacetylase inhibitors, as well as metalloprotease and angiogenesis inhibitors. Sample Phase I and Phase II clinical trial designs are reviewed using modulation of molecular markers and breast intraepithelial neoplasia as the major endpoints.
The Electrochemistry of Surface Oxidation of Chalcopyrite (1985)

Linear sweep voltammetry with a freshly renewed surface of a chalcopyrite mineral electrode shows a small anodic prewave in acid electrolytes. The main anodic reaction, with complete dissolution of copper and iron, occurs at more positive potentials. Experiments under nitrogen show that the prewave is not a consequence of atmospheric oxidation during surface preparation. The prewave represents a surface oxidation of chalcopyrite to form a thin passivating film. The charge passed in forming this film is around 2 mC cm−2 for a polished surface. The prewave reaction is identified with the initial phase of the oxidative dissolution or leaching of chalcopyrite. Contrary to the reported behavior at 80°C, the surface film is stable at 25°C for long periods at open circuit. Various evidence, including the relative charges passed in forming and then reducing the surface film, and the presence of dissolved copper, leads to the following suggested stoichiometry for the prewave reaction
Production Strategies and Applications of Microbial Single Cell Oils (2016)

Polyunsaturated fatty acids (PUFAs) of the ω-3 and ω-6 class (e.g., α-linolenic acid, linoleic acid) are essential for maintaining biofunctions in mammalians like humans. Due to the fact that humans cannot synthesize these essential fatty acids, they must be taken up from different food sources. Classical sources for these fatty acids are porcine liver and fish oil. However, microbial lipids or single cell oils, produced by oleaginous microorganisms such as algae, fungi and bacteria, are a promising source as well. These single cell oils can be used for many valuable chemicals with applications not only for nutrition but also for fuels and are therefore an ideal basis for a bio-based economy. A crucial point for the establishment of microbial lipids utilization is the cost-effective production and purification of fuels or products of higher value. The fermentative production can be realized by submerged (SmF) or solid state fermentation (SSF). The yield and the composition of the obtained microbial lipids depend on the type of fermentation and the particular conditions (e.g., medium, pH-value, temperature, aeration, nitrogen source). From an economical point of view, waste or by-product streams can be used as cheap and renewable carbon and nitrogen sources. In general, downstream processing costs are one of the major obstacles to be solved for full economic efficiency of microbial lipids. For the extraction of lipids from microbial biomass cell disruption is most important, because efficiency of cell disruption directly influences subsequent downstream operations and overall extraction efficiencies. A multitude of cell disruption and lipid extraction methods are available, conventional as well as newly emerging methods, which will be described and discussed in terms of large scale applicability, their potential in a modern biorefinery and their influence on product quality. Furthermore, an overview is given about applications of microbial lipids or derived fatty acids with emphasis on food applications.
Ultraviolet upconversion fluorescence from ^6D_J of Gd^3+ induced by 980 nm excitation (2008)

Ultraviolet upconversion emissions of 246.2 and 252.8 nm from (6)D(J) levels of Gd(3+) ions were observed in GdF(3): 10% Yb(3+), 0.7% Tm(3+) nanocrystals under 980 nm excitation from a laser diode. The (6)D(J) levels of Gd(3+) ions can be efficiently populated by energy transfer processes of Yb-->Tm-->Gd and Yb-->Gd. A six-photon upconversion process was confirmed by the dependence of 252.8 nm emission intensity on the pumping power. The upconversion mechanism in the six-photon process was discussed based on excited state absorption of Gd(3+) ions, cross relaxation energy transfer between two excited Gd(3+) ions, and energy transfer between Gd(3+) and Yb(3+) or Tm(3+) ions.
Networks of local minima in optical system optimization (2004)

We discuss a surprising new feature of the merit function landscape in optical system design. When certain conditions are satisfied, the local minima form a network in which all nodes are connected. Each link between two neighboring minima contains a saddle point with a Morse index of 1. For a simple global optimization search (the symmetric Cooke triplet), the network of the corresponding set of local minima is presented.
Inhibition of Apoptosis and Augmentation of Lymphoproliferation inbcl-2Transgenic Fas/Fas Ligand-Defective Mice (1996)

Mice defective in Fas (CD95 or APO-1) or its ligand (lpr or gld mice) develop age-dependent lymphadenopathy and systemic autoimmune disease. T cells accumulating in the lymph nodes of these mice express reduced levels of Bcl-2 protein and are susceptible to spontaneous and glucocorticoid-induced apoptosis. We backcrossed bcl-2 transgenic mice to lpr and gld mice to homozygosity to determine the effects of Bcl-2 overexpression. T cells in these mice were resistant to spontaneous and glucocorticoid-induced apoptosis in vitro. Moreover, the accumulation of CD4(-)CD8(-) T cells in the lymph nodes and the spleens was augmented, suggesting that a Bcl-2-dependent mechanism regulating the number of T cells residing in the peripheral lymphoid organs in addition to the Fas-mediated pathway exists.
The Effect of Walking Speed and Adding a Backpack on Trunk Dynamics During Treadmill Walking (2002)

To determine the effects of load carriage and walking speed on stride parameters and the coordination of trunk movements, twelve subjects walked on a level treadmill at a range of walking speeds (0.6 m/s - 1.6 m/s) with and without a backpack containing 40% of their body mass. It was hypothesized that compared to unloaded walking load carriage decreases transverse pelvic and thoracic rotation, the mean relative phase between pelvic and thoracic rotations, and increases hip excursion. In addition, it was hypothesized that these changes would coincide with a decreased stride length and increase stride frequency. The findings supported the hypotheses. It was additionally hypothesized that the increased MOI of the upper body caused by the added mass of the backpack would result in an increase in upper body torque, an increase in lower body torque, and an increase in net body torque. Higher levels of upper body torque were observed in the backpack condition compared to the no backpack condition. However, the increase in upper body torque was 225%, while upper body MOI increased by 400%. In contrast to our hypothesis, decreased lower body torque was also observed in the backpack condition compared to the no backpack condition Dimensionless analyses indicated that there was a significantly larger contribution of hip excursion and smaller contribution on transverse plane pelvic rotation to increases in stride length during load carriage. In addition, there was a significant effect of load carriage on the amplitudes of transverse pelvic and thoracic rotation and the relative phase of pelvic and thoracic rotation. It was concluded that the shorter stride length and higher stride frequency observed when carrying a backpack is the result of decreased pelvic rotation. The shorter stride length and higher stride frequency observed during load carriage are associated with changes in transverse plane kinematics.

An alternative approach to call/connection control in broadband switching systems (1995)

Using a client-server based signaling protocol, the authors propose a new approach to connection establishment that allows for the easy handling of multiparty connections and improves end-to-end connection setup delay by parallelizing certain operations that occur during connection establishment. We refer to the current approach as the call processing/broadband ISDN user part (CP/B-ISUP) approach. To illustrate the procedure description for call/connection establishment, we assume a network topology of three switches and one signaling transfer point (STP). The STP provides datagram routing for signaling messages. Associated with each switch is a call processing application process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Brand Loyalty Vs. Repeat Purchasing Behavior (1973)

Brand loyalty is first distinguished from simple repeat purchasing behavior and then conceptually defined in terms of six necessary and collectively sufficient conditions. An experiment designed to test this conceptualization provided strong empirical support for the distinction as conceptualized.
