[An application of the approach combining wavelet transform and energy entropy to remove electrocardiography interference in diaphragmatic electromyographic]. (2013)

Diaphragmatic electromyographic (EMGdi) signal is a weak biological signal, which contains some significant physiological information of our body respiration system and is susceptible to strong electrocardiography (ECG) signal interference. Based on wavelet transform and theory of information entropy, a new wavelet energy entropy threshold algorithm to remove ECG interference is proposed in this paper. On the base of analysis of wavelet coefficients of each scale, the method sees the information of each scale as a single signal source, equalizes it byzones, and then divides the energy entropy into two categories (i. e., high energy entropy and low energy entropy) through the distribution characteristics of energy entropy of each zone to conduct absolute mean value threshold. In addition, the denoised signal is reconstructed by wavelet coefficients processed. The experimental results showed that the method removed the ECG signal in EMGdi effectively and reserved the available characteristics of EMGdi better.
Detection caching for faster object detection (2011)

This paper investigates how the speed of an object detector can be rapidly increased through a caching framework when input sequences are quasi-repetitive. In the proposed framework, observed output states are discretized into a large number of classes. Each class induces its own discriminant subspace in the feature space, and is associated with a feature exemplar and a local metric. The feature exemplars and the local metrics are learned online using a novel piecewise linear discriminant analysis. The execution of the original object detector is skipped when the current image feature vector is similar to previously observed feature exemplars, and previously detected object states may simply be recalled. The exemplar recognition is carried via a 1-pass approximate nearest neighbor search in an index tree based on k-means clustering. Preliminary results show up to a 5-fold improvement when applied to the Viola &amp; Jones [23] face detector, improving speeds from 10fps to 50fps. Experiments were done on the standard MPEG-4 testing sequences and real data. 1.1. Detection Caching At the heart of the framework in this paper is the notion that for quasi-repetitive input, it is often much faster recalling previous results from the object detector, than to re-execute the object detector on the same input again. Consider the Viola and Jones face detector [23] which linearly scans through different (x, y, s) states (where s is scale) and evaluates each bounding window to determine whether a face is present or not through a binary classifier. However, if it is possible to identify if a particular image frame (i.e. the entire image frame, not just a particular bounding window) has been previously observed before, the previous (x, y, s) state may simply be recalled – this is multi-class classification, where each parameter state is a separate class (figure 1). Furthermore, the recognition of the image frame may involve a tree-based search in log (rather than linear) number of operations. 1.
A survey of power management techniques in mobile computing operating systems (1995)

Many factors have contributed to the birth and continued growth of mobile computing, including recent advances in hardware and communications technology. With this new paradigm however come new challenges in computer operating systems development. These challenges include heretofore relatively unusual items such as frequent network disconnections, communications bandwidth limitations, resource restrictions, and power limitations. It is the last of these challenges that we shall explore in this paper---that is the question of what techniques can be employed in mobile computer operating systems that can reduce the power consumption of today's mobile computing devices.
A Framework for Reconciling Attribute Values from Multiple Data Sources (2007)

Because of the heterogeneous nature of different data sources, data integration is often one of the most challenging tasks in managing modern information systems. While the existing literature has focused on problems such as schema integration and entity identification, it has largely overlooked a basic question: When an attribute value for a real-world entity is recorded differently in different databases, how should the “best” value be chosen from the set of possible values? This paper provides an answer to this question. We first show how a probability distribution over a set of possible values can be derived. We then demonstrate how these probabilities can be used to solve a given decision problem by minimizing the total cost of type I, type II, and misrepresentation errors. Finally, we propose a framework for integrating multiple data sources when a single “best” value has to be chosen and stored for every attribute of an entity.
Electrical Switching in Thin Film Structures Based on Molybdenum Oxides (2014)

We report on the experimental study of electrical instabilities in thin film structures on the basis of molybdenum oxides. Thin films of molybdenum oxide are obtained by thermal vacuum evaporation and anodic oxidation. The results of X-ray structural analysis, investigation of optical and electrical properties, are presented. It is shown that the initial vacuum-deposited oxide represents amorphous MoO 3 . In the MOM (metal-oxide-metal) structures with Mo oxide films obtained by the two methods, the effect of electrical switching with an S-shaped current-voltage characteristic is found. We put forward a hypothesis according to which the switching mechanism is associated with the development of electrical instability caused by the insulator-to-metal transition in Mo 8 O 23 . The switching channel, comprising this lower valence oxide, emerges in the initial film during the process of electrical forming of the MOM structure. The obtained results indicate the possibility of application of these structures in oxide micro- and nanoelectronics as electronic switches and other electronic devices.
Inhibition of the MEK/ERK Signaling Pathway Blocks a Subset of B Cell Responses to Antigen (2001)

Signal transduction initiated by B cell Ag receptor (BCR) cross-linking plays an important role in the development and activation of B cells. Therefore, considerable effort has gone into determining the biochemical signaling events initiated by the BCR and delineating which events participate in specific biological responses to Ag. We used two inhibitors of mitogen-activated protein kinase/extracellular signal-regulated kinase kinase (MEK) 1 and MEK2, PD98059, and U0126, to assess the role the Ras-mitogen-activated protein kinase pathway plays in several BCR-induced responses. PD98059 or U0126 treatment substantially inhibited the BCR-induced activation of the extracellular signal-regulated kinase (ERK) forms of mitogen-activated protein kinase in the immature B cell line WEHI-231, in immature splenic B cells, and in mature splenic B cells. However, MEK-ERK inhibition did not block BCR-induced growth arrest or apoptosis of WEHI-231 cells or apoptosis of immature splenic B cells, indicating that the MEK-ERK pathway is not required for these events. In contrast, PD98059 and U0126 treatment did inhibit the up-regulation of specific BCR-induced proteins, including the transcription factor Egr-1 in WEHI-231 and mature splenic B cells, and the CD44 adhesion molecule and CD69 activation marker in mature splenic B cells. Moreover, both inhibitors suppressed BCR-induced proliferation of mature splenic B cells, in the absence and in the presence of IL-4. Therefore, activation of the MEK-ERK pathway is necessary for a subset of B cell responses to Ag.
Estimate of the Activation Energies for Boundary Diffusion from Rate‐Controlled Sintering of Pure Alumina, and Alumina Doped with Zirconia or Titania (1990)

Sintering experiments at constant heating rates were employed to estimate the activation energy for sintering in alumina and in alumina containing 5 vol% zirconia or 5 vol% titania. Grain growth, which can complicate the analysis of sintering kinetics data, was suppressed by using uniformly and densely packed grain compacts prepared by colloidal processing. Grain‐boundary diffusion is believed to have been the dominant sintering mechanism. The activation energies were 440 ± 40 kJ/mol for pure alumina, 585 ± 40 kJ/mol for alumina (titania), and 730 ± 60 kJ/mol for alumina (zirconia). The alumina and alumina (titania) results are in agreement with the values reported in the literature. The possibility that the higher activation energies for doped alumina reflect a stronger bonding at alumina interfaces in the presence of zirconium and titanium is discussed.
CYTOGENETIC STUDIES IN<i>ARABIDOPSIS THALIANA</i> (1970)

The five primary trisomics and one telotrisomic of Arabidopsis have been established and identified with respect to known linkage groups. From diplotene preparations the chromosome complement was seen to comprise one long, three medium, and one short chromosome. All the trisomics except Fragilis were transmitted through the male (in frequencies up to 22%). There appears to be some selection against disomic eggs, only 21-30% recovery being observed from selfed trisomics. No tetrasomics were found.
Design of a low-distortion 22-kHz fifth-order Bessel filter (1993)

A linearity improvement technique employing passive resistors and current-steering MOS transistors as a variable resistance element is proposed to implement a low-distortion filter in CMOS technology. This proposed implementation relies on the linearity of the passive resistors and the tunability of the current-steering MOS transistors operating in the triode region to overcome the limited linearity performance in continuous-time electronically tunable filters. By using the existing systematic feedback loops in the active filters and placing the nonlinear elements inside the feedback, the distortion resulting from the nonlinear devices is greatly reduced by the filter loop gain. A 22-kHz fifth-order Bessel filter, its dynamic range optimized by applying Karmarkar's rescaling algorithm and self-tuned with a switched-capacitor reference resistor, demonstrates better than -90-dB THD with a 2-kHz, 4-V/sub pp/ signal in 5-V 2- mu m CMOS.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Variant forms of rat epidermal growth factor present in the urine of nude rats bearing human tumors. (1988)

Epidermal growth factor (EGF) receptor-binding peptides from the urine of tumor patients have been reported to differ in molecular weight and relative hydrophobicity from those of normal individuals. Nude rats bearing human large cell lung carcinomas or chondrosarcomas and non-tumor-bearing sibling control rats were used to investigate the contributions of tumor and host to urinary EGF-related peptide growth factors. Peptides were adsorbed from urine onto methyl-bonded silica and eluted according to their relative hydrophobicity by a stepwise gradient of aqueous acetonitrile. Total EGF receptor-binding activity relative to urinary creatine was elevated in the urine of only one group of tumor-bearing rats. However, the proportion of relatively hydrophilic activity was increased markedly in all three groups of tumor-bearing rats. Rats bearing a large cell lung cancer excreted unusually hydrophilic Mr 6000 peptides that were chromatographically similar to transforming growth factor alpha on reverse phase high performance liquid chromatography but proved to be rat EGF by radioimmunoassay (RIA). EGF receptor-binding activity that was common to the urine of tumor-bearing animals regardless of tumor type, but more hydrophilic than that from control rats, had Mr 60,000, 30,000, 12,000, and 4,000 to 7,000 components. All reacted fully in the rat EGF RIA and were negative for human EGF and transforming growth factor alpha by RIA. A more hydrophobic fraction of EGF receptor-binding activity, common to control and tumor-bearing animals, contained Mr 33,000, 5,000 to 7,000, and 2,000 to 5,000 components. High performance liquid chromatography and gel electrophoresis of the Mr 33,000 activity revealed a high molecular weight rat EGF comparable to that reported in human urine. No human EGF or transforming growth factor alpha was detected by RIA in any of the active fractions from tumor-bearing rat urine. Thus, all EGF receptor-binding activity appeared to derive from rat EGF produced by the rat host and not by the xenografted tumors.
Gallium-pyridoxal isonicotinoyl hydrazone (Ga-PIH), a novel cytotoxic gallium complex. A comparative study with gallium nitrate. (1998)

The anti-proliferative activity of gallium-pyridoxal isonicotinoyl hydrazone (Ga-PIH), a novel gallium complex was compared with that of gallium nitrate, a known anti-tumor agent. At 50 microM, Ga-PIH inhibited CCRF-CEM cell growth by 45% compared to < 10% inhibition with gallium nitrate or PIH. The IC50s for Ga-PIH, gallium nitrate and PIH were 60, 84 and 68 microM respectively. The addition of exogenous iron as transferrin-iron to the culture medium reversed the cytotoxicity of gallium nitrate and PIH in a dose-dependent manner but had only minor effects on the cytotoxicity of Ga-PIH. The effect of these compounds on cellular iron uptake was measured since prior studies have shown that gallium perturbs iron transport into cells. Fifty micromolar Ga-PIH, gallium nitrate or PIH inhibited the cellular uptake of 59Fe-transferrin over 24 h by 65%, 32%, and 78% respectively. Although all three compounds inhibited iron uptake, only Ga-PIH produced a significant upregulation of cellular transferrin receptors. Since the cytotoxicity of Ga-PIH appears to be less influenced by extracellular iron and cellular transferrin receptor expression, it may have potential as an antineoplastic agent and should be further evaluated in animal tumor models.
Feminist Perspectives on Whiteness (2016)

Interdisciplinary feminist perspectives of whiteness have developed since the 1970s and shifted over time as new conceptions of whiteness and new racial processes have unfolded. Feminist scholars have analyzed whiteness as a socially constructed category rather than a biological reality and considered its multidimensional expressions and its effects on embodied beings. Key feminist contributions to the investigation of whiteness have included both expanding the concept of whiteness beyond a masculine subject and the concept of intersectionality, which refers to the multiple and intersecting aspects of identity and oppression that shape people's lives. Although feminist scholars have offered salient critiques about the limits of whiteness studies as an anti‐racist endeavor, new approaches for conceptualizing and investigating whiteness emerge through postcolonial, indigenous, and transnational lenses.
Exploiting speaker segmentations for automatic role detection. An application to broadcast news documents (2010)

In the field of automatic audiovisual content-based indexing and structuring, finding events like interviews, debates, reports, or live commentaries requires to bridge the gap between low-level feature extraction and such high-level event detection. In our work, we consider that detecting speaker role to enrich interaction sequences between speakers is a first step to reach this goal. The generic method we propose follows a data mining approach. We assume that speaker roles can emerge from parameters extracted from speaker segmentations without taking any prior information into account. Each speaker is then represented by a feature vector carrying temporal, signal and prosodic information. In this paper, we study how methods for dimensionality reduction and classification can help to recognize speaker roles. This method is applied to the corpus of the ESTER2 evaluation campaign and our best result reaches about 72% of well recognized roles that corresponds to nearly 79% of speech time.

Five-Port Optical Router Based on Microring Switches for Photonic Networks-on-Chip (2013)

We demonstrate a five-port optical router that is suitable for large-scale photonic networks-on-chip. The optical router is designed to passively route the optical signal travelling in one direction and actively route the optical signal making a turn. In the case that an XY dimension-order routing is used, the passive routing feature guarantees that the maximum power consumption to route the data through the network is a constant that is independent of the network size. The fabricated device has an efficient footprint of ~ 460 × 1000 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The routing functionality of the device is verified by using a 12.5-Gbit/s optical signal. The capability of multiwavlength routing for the optical router is also explored and discussed.
INVESTIGATIONS ASSOCIATED WITH THE TRANSPLANTATION OF BOVINE OVA (1962)

Summary. Synchronization of bovine oestrous cycles was studied with respect to methods of accomplishment. A total of 328 cows were recycled by: (a) daily subcutaneous injections of progesterone, (b) larger subcutaneous injections every 3rd day and (c) corpus luteum expression. Standing oestrous was exhibited by 262 cows. Twelve did not exhibit oestrus and fifty-four exhibited symptoms but refused mounting. Time between treatment and oestrus was 4·97 ±1 82, 6·52 ±1 ·25 and 2 ·84 ±0·68 days, respectively, for the three methods employed. Length of time between injection and oestrus did not differ significantly as influenced by day of initiation, the duration of injections or by superovulation. Differences between fifty-nine recycled and fifty-three control cows, with respect to rate of conception, were not significant nor were differences between the first and second services after recycling.
A Hybrid Model for Book Recommendation (2018)

Recommendations are an important part of various e-commerce and seller websites. Recommending a product to the users has helped a lot of these companies in predicting the interests on that product. Recommendation are personalized display of products after narrowing down the thousands of items in the inventory to a useful few. A Book Recommendation Engine can be helpful to many people as they will be suggested what book to read next. These can be learned from the user's choices over time and a ‘taste’ profile can be created by it. Existing approaches for Recommending involves selecting from two of the popular approaches i.e Collaborative learning and Content Based learning. User Collaborative learning works by finding similar user with the taste of target user and by recommending it according to the choice of a similar user while Content based-learning involves actually having the ‘knowledge’ of the item and then recommending the item to the target user based on the user's ‘taste’ profile. Since both these works well separately they can be used simultaneously making a hybrid learning and give the user more accurate results since they are combined together.

Cerebral amyloid angiopathy--a disease or age-related condition. (2006)

Cerebral amyloid angiopathy is characterized by deposition of amyloid in the walls of leptomeninged and cerebral blood vessels. Its most common form, sporadic CAA that results from deposition of beta-amyloid peptide, which is the subject of this short review, is present in virtually all cases of Alzheimer disease and is also common among non-demented subjects where its prevalence increases with age. Stroke due to massive cerebral lobar hemorrhage is the main clinical presentation of CAA, but transient neurologic symptoms due to microhemorrhages may also occur. CAA is also a risk factor for cerebral infarction and there is increasing evidence that CAA contributes to cognitive impairment in the elderly, usually in association with white matter abnormalities on imaging. Although the definitive diagnosis of CAA is neuropathologic, reliable diagnosis can be reached clinically, based on the occurrence of strictly lobar hemorrhages, particularly in the cortico-subcortical area when using gradient-echo or T2*-weighted magnetic resonance imaging. Experimental studies have shown that the origin of the vascular amyloid is neuronal, and that age-related degenerative changes in the vessel walls prevent its clearance from the brain along perivascular spaces and promote Abeta aggregation and CAA formation. The entrapped Abeta aggregates are toxic to various vascular wall components, including smooth muscle cells, pericytes and endothelial cells, leading to their eventual destruction and predisposition of the vessel wall to rupture and hemorrhage. However, more research is necessary to decipher the mechanism of CAA formation and its relation to cognitive decline in the elderly.
Selection of Reference Group, Perceived Reference Group Permissiveness, and Personal Permissiveness Attitudes and Behavior: A Study of Two Consecutive Panels (1967-1971; 1970-1974) (1976)

Employing two sequential, and partially overlapping panels of white, single students, covering the years 1967-1971 and 1970-1974, measurement was made (both longitudinally and cross-sectionally) of reference group selection with regard to sexual standards, perceived reference group norms with respect to premarital sexual permissiveness and the relationship of these variables to premarital sexual attitudes and behavior. Findings included: (a) selection of reference groups predominantly followed peer to peer and/or parent to peer patterns from Ti to T2 for both panels; (b) permissiveness increased from Ti to T2 for both panels, with significant changes in the same people-these changes were greater fobrfemales than for males; (c) selection of peers at TI and T2 and movement from selection oqfparents at TI to selection of peers at T2 were related to significant shifts of respondents in premarital sexual attitudes and behavior, in the direction qf greater permissiveness; (d) perception of reference group permissiveness at T2 which exceeded that perceived at Ti was related to significant shifts of respondents in premarital sexual attitudes and behavior, in the direction of greater permissiveness.
Information enquiry kiosk with multimodal user interface (2009)

A multimodal interactive dialogue automaton (kiosk) for self-service is presented in the paper. Multimodal user interface allow people to interact with the kiosk by natural speech, gestures additionally to the standard input and output devices. Architecture of the kiosk contains key modules of speech processing and computer vision. An array of four microphones is applied for far-field capturing and recording of user’s speech commands, it allows the kiosk to detect voice activity, to localize sources of desired speech signals, and to eliminate environmental acoustical noises. A noise robust speaker-independent recognition system is applied to automatic interpretation and understanding of continuous Russian speech. The distant speech recognizer uses grammar of voice queries as well as garbage and silence models to improve recognition accuracy. Pair of portable video-cameras are applied for vision-based detection and tracking of user’s head and body position inside of the working area. Russian-speaking talking head serves both for bimodal audio-visual speech synthesis and for improvement of communication intelligibility by turning the head to an approaching client. Dialogue manager controls the flow of dialogue and synchronizes sub-modules for input modalities fusion and output modalities fission. The experiments made with the multimodal kiosk were directed to cognitive and usability studies of human-computer interaction by different communication means
