Platelet antibody: Review of detection methods (1988)

The driving force behind development of in vitro methods for platelet antibodies is identification of plasma factors causing platelet destruction. Early methods relied on measurement of platelet activation. Current methods are more specific and use a purified antibody against immunoglobulin or complement, which is usually labeled with 125I or tagged with an enzyme or fluorescein. Comparisons of quantitation of platelet-associated IgG show wide variability between different methods. The disparate results can be related both to differences in binding of secondary antibodies to immunoglobulin in solution compared to immunoglobulins attached to platelets and to the improper assumption that the binding ratio between the secondary detecting and primary antiplatelet antibody is one. Most assays can 1) identify neonatal isoimmune thrombocytopenia and posttransfusion purpura, 2) help to differentiate between immune and nonimmune thrombocytopenias, 3) help to sort out the offending drug when drug-induced thrombocytopenia is suspected, and 4) identify platelet alloantibodies and potential platelet donors via a cross match assay for refractory patients. However, the advantages of quantitative assays over qualitative methods with respect to predictions of patients clinical course and response to different treatments remain to be investigated.
Digital Predistortion Using Stochastic Conjugate Gradient Method (2011)

This paper is concerned with digital predistortion for linearization of RF high power amplifiers (HPAs). An iterative stochastic conjugate gradient (SCG) method is used in computing the predistorter in the digital predistortion. We also propose an adaptive scheme for selecting basis functions in the SCG computations. The adaptive scheme with SCG has the advantage of reducing the complexity and, at the same time, increasing the convergence rate and stability of iteration. We present some results of using the SCG in a hardware platform with a solid state HPA.
A Transcript Profiling Approach Reveals an Abscisic Acid-Specific Glycosyltransferase (UGT73C14) Induced in Developing Fiber of Ligon lintless-2 Mutant of Cotton (Gossypium hirsutum L.) (2013)

Ligon lintless-2, a monogenic dominant cotton (Gossypium hirsutum L.) fiber mutation, causing extreme reduction in lint fiber length with no pleiotropic effects on vegetative growth, represents an excellent model system to study fiber elongation. A UDP-glycosyltransferase that was highly expressed in developing fibers of the mutant Ligon lintless-2 was isolated. The predicted amino acid sequence showed ~53% similarity with Arabidopsis UGT73C sub-family members and the UDP-glycosyltransferase was designated as UGT73C14. When expressed in Escherichia coli as a recombinant protein with a maltose binding protein tag, UGT73C14 displayed enzymatic activity toward ABA and utilized UDP-glucose and UDP-galactose as the sugar donors. The recombinant UGT73C14 converted natural occurring isoform (+)-cis, trans-ABA better than (+)-trans, trans-ABA and (-)-cis, trans-ABA. Transgenic Arabidopsis plants constitutively overexpressing UGT73C14 did not show phenotypic changes under standard growth conditions. However, the increased glycosylation of ABA resulted in phenotypic changes in post-germinative growth and seedling establishment, confirming in vivo activity of UGT73C14 for ABA. This suggests that the expression level of UGT73C14 is regulated by the observed elevated levels of ABA in developing fibers of the Li 2 mutant line and may be involved in the regulation of ABA homeostasis.
Neuromorphic Atomic Switch Networks (2012)

Efforts to emulate the formidable information processing capabilities of the brain through neuromorphic engineering have been bolstered by recent progress in the fabrication of nonlinear, nanoscale circuit elements that exhibit synapse-like operational characteristics. However, conventional fabrication techniques are unable to efficiently generate structures with the highly complex interconnectivity found in biological neuronal networks. Here we demonstrate the physical realization of a self-assembled neuromorphic device which implements basic concepts of systems neuroscience through a hardware-based platform comprised of over a billion interconnected atomic-switch inorganic synapses embedded in a complex network of silver nanowires. Observations of network activation and passive harmonic generation demonstrate a collective response to input stimulus in agreement with recent theoretical predictions. Further, emergent behaviors unique to the complex network of atomic switches and akin to brain function are observed, namely spatially distributed memory, recurrent dynamics and the activation of feedforward subnetworks. These devices display the functional characteristics required for implementing unconventional, biologically and neurally inspired computational methodologies in a synthetic experimental system.
The concept of differential hardness in depth sensing indentation (2003)

Since in-depth sensing indentation load-depth data of the entire loading-unloading cycle are available, more information than a single hardness value and an elastic modulus can be extracted from the experimental data. The conventional hardness H(h) = F(h)/AC(h) and the differential hardness Hd(h) = dF/dAC are calculated as continuous functions of depth h and compared to each other in this paper (F: load, AC: contact area). It turns out that Hd describes the momentary material resistance to deformation, whereas H integrates over deformation states from first tip-sample contact to current penetration h. This difference is particularly important for materials not homogeneous in depth (e.g. layer systems), and for situations where time-dependent external factors influence the momentary deformation resistance. Photoplasticity is considered as an example for the latter.
21-Component compositionally complex ceramics: Discovery of ultrahigh-entropy weberite and fergusonite phases and a pyrochlore-weberite transition (2022)

Abstract Two new high-entropy ceramics (HECs) in the weberite and fergusonite structures, along with the unexpected formation of ordered pyrochlore phases with ultrahigh-entropy compositions and an abrupt pyrochlore-weberite transition, are discovered in a 21-component oxide system. While the Gibbs phase rule allows 21 equilibrium phases, 9 out of the 13 compositions examined possess single HEC phases (with ultrahigh ideal configurational entropies: ∼2.7 k B per cation or higher on one sublattice in most cases). Notably, (15RE 1/15 )(Nb 1/2 Ta 1/2 )O 4 possess a single monoclinic fergusonite (C2/ c ) phase, and (15RE 1/15 ) 3 (Nb 1/2 Ta 1/2 ) 1 O 7 form a single orthorhombic (C222 1 ) weberite phase, where 15RE 1/15 represents Sc 1/15 Y 1/15 La 1/15 Pr 1/15 Nd 1/15 Sm 1/15 Eu 1/15 Gd 1/15 Tb 1/15 Dy 1/15 Ho 1/15 Er 1/15 Tm 1/15 Yb 1/15 Lu 1/15 . Moreover, a series of eight (15RE 1/15 ) 2+ x (Ti 1/4 Zr 1/4 Ce 1/4 H 1/4 ) 2−2 x (Nb 1/2 Ta 1/2 ) x O 7 specimens all exhibit single phases, where a pyrochlore-weberite transition occurs within 0.75 < x < 0.8125. This cubic-to-orthorhombic transition does not change the temperature-dependent thermal conductivity appreciably, as the amorphous limit may have already been achieved in the ultrahigh-entropy 21-component oxides. These discoveries expand the diversity and complexity of HECs, towards many-component compositionally complex ceramics (CCCs) and ultrahigh-entropy ceramics.
Catching Synchronized Behaviors in Large Networks (2016)

Given a directed graph of millions of nodes, how can we automatically spot anomalous, suspicious nodes judging only from their connectivity patterns? Suspicious graph patterns show up in many applications, from Twitter users who buy fake followers, manipulating the social network, to botnet members performing distributed denial of service attacks, disturbing the network traffic graph. We propose a fast and effective method, C atch S ync , which exploits two of the tell-tale signs left in graphs by fraudsters: (a) synchronized behavior: suspicious nodes have extremely similar behavior patterns because they are often required to perform some task together (such as follow the same user); and (b) rare behavior: their connectivity patterns are very different from the majority. We introduce novel measures to quantify both concepts (“synchronicity” and “normality”) and we propose a parameter-free algorithm that works on the resulting synchronicity-normality plots. Thanks to careful design, C atch S ync has the following desirable properties: (a) it is scalable to large datasets, being linear in the graph size; (b) it is parameter free ; and (c) it is side-information-oblivious : it can operate using only the topology, without needing labeled data, nor timing information, and the like., while still capable of using side information if available. We applied C atch S ync on three large, real datasets, 1-billion-edge Twitter social graph, 3-billion-edge, and 12-billion-edge Tencent Weibo social graphs, and several synthetic ones; C atch S ync consistently outperforms existing competitors, both in detection accuracy by 36% on Twitter and 20% on Tencent Weibo, as well as in speed.
Practical and Effective Re-Pair Compression (2017)

Re-Pair is an efficient grammar compressor that operates by recursively replacing high-frequency character pairs with new grammar symbols. The most space-efficient linear-time algorithm computing Re-Pair uses $(1+ε)n+\sqrt n$ words on top of the re-writable text (of length $n$ and stored in $n$ words), for any constant $ε>0$; in practice however, this solution uses complex sub-procedures preventing it from being practical. In this paper, we present an implementation of the above-mentioned result making use of more practical solutions; our tool further improves the working space to $(1.5+ε)n$ words (text included), for some small constant $ε$. As a second contribution, we focus on compact representations of the output grammar. The lower bound for storing a grammar with $d$ rules is $\log(d!)+2d\approx d\log d+0.557 d$ bits, and the most efficient encoding algorithm in the literature uses at most $d\log d + 2d$ bits and runs in $\mathcal O(d^{1.5})$ time. We describe a linear-time heuristic maximizing the compressibility of the output Re-Pair grammar. On real datasets, our grammar encoding uses---on average---only $2.8\%$ more bits than the information-theoretic minimum. In half of the tested cases, our compressor improves the output size of 7-Zip with maximum compression rate turned on.
Electrochemical Characteristics of Carbide-Derived Carbon∣1-Ethyl-3-methylimidazolium Tetrafluoroborate Supercapacitor Cells (2010)

Supercapacitor (SC) cells based on microporous titanium carbide-derived carbon [C(TiC)] electrodes in room temperature ionic liquid (1-ethyl-3-methylimidazolium tetrafluoroborate) have been tested by cyclic voltammetry, constant current charge/discharge, and electrochemical impedance methods at temperatures from 25 to . The limits of ideal polarizability, low frequency limiting capacitance and series resistance, time constant, complex power components, time stability, and other characteristics have been calculated and discussed. The influence of temperature on the cell capacitance, characteristic time constant values, and region of ideal polarizability has been analyzed. The comparatively high energy and power densities per active C(TiC) weight have been calculated, weakly depending on temperature, if . A comparison of the results to the corresponding data for the system indicates that 1-ethyl-3-methylimidazolium -derived carbon SC cells demonstrate lower power densities, a narrower region of ideal polarizability, and a lower constant current cyclability at higher charge/discharge rates.
Growth and meat quality of broiler chicks fed with fermented fish viscera silage. (1996)

Fermented silage from fish viscera was prepared by homogenizing with lO%molasses,O.5%propionic\nacid (antimycotic agent) and 0.02% ethoxyquin (antioxidant). Isonitrogenous (21% protein) and\nisocaloric (ME=2900K Cal/kg) diets for broiler chicks were formulated replacing 25% and 50% fish meal\nby fish viscera silage. Fish meal at 8% (w/w) was kept as control. Consumption of diets containing silage\nwas 7.3% lower, resulting into about 5% reduction in growth compared to control. Comulative feed\nconversion ratio was in the range of 2.20 to 2.29 and was not influenced by diets. Silage also had no marked\neffect on dressing yields (68.2-68.4%), meat: bone ratio (3.9-4.0) and muscle composition. Analysis of\nranksums for sensory quality attributes of muscle from both silage fed and fish meal fed birds indicated\nthat the differences were not significant (P>0.05). The findings suggest that fish meal upto 50% can be\nreplaced by fish viscera silage in broiler diets without significantly affecting growth and meat quality.
Water Budget (2017)

The analysis of the source of the Earth's waters has long been a subject of first speculation, and, since the scientific revolution, a source of scientific inquiry. The components of the hydrologic cycle were commented upon in classical times and put into a cyclical model of evaporation, condensation, and precipitation by the Roman architect and engineer Vitruvius circa 0 bce . By the seventeenth and eighteenth centuries, actual measurements of precipitation, stream flow, and evaporation demonstrated that no mysterious processes were required to account for the waters in the Earth's hydrologic cycle. Improved measurement of precipitation and stream flow permitted calculation of the first water budgets for surface basins. Accurate modeling of water budgets for specific areas has been hindered by the difficulty in measuring evapotranspiration and groundwater input, storage, and release. The work of C.W. Thornthwaite was fundamental in developing models to estimate potential and actual evapotranspiration. Groundwater models were initially developed from solving for the residual from other components of the water budget, including precipitation, evapotranspiration, and surface runoff. Since the 1960s data on aquifer characteristics and measurements of groundwater flow have produced more accurate assessment of groundwater inputs, storage, and outputs. The increasing demand on water supplies has led to legal mandates to develop computer‐based water budget models to assess and manage both surface water and aquifers.
6.9 A 1.1µm 33Mpixel 240fps 3D-stacked CMOS image sensor with 3-stage cyclic-based analog-to-digital converters (2016)

There is an increasing demand for high-reality video systems. The ITU-R has standardized video parameters for ultra-high-definition TV (UHDTV), and the full-specification video signal stated in this international standard is prescribed as having a 7,680 (H) × 4,320 (V) pixel count, 120Hz frame frequency with progressive scanning, 12b tone reproduction, and wide color gamut. A 33Mpixel 120fps CMOS image sensor with a 12b column-parallel analog-to-digital converter (ADC) is reported in [1]. In addition to standard operation, higher sensitivity, smaller pixels, and a higher frame rate of 240fps or more are required for CMOS image sensors. Backside-illuminated stacked CMOS image sensors [2] are effective for simultaneously achieving both high sensitivity for small pixels and high operation speed. However, these stacked structures are still insufficient for high-frame-rate UHDTV image sensors since the pixel wafer and the ASIC wafer are connected by through-silicon vias in the peripheral area.
Addition of Soybean Lipoxygenase to All-Purpose Flour and its Effects on Dough Gluten Strength and Bread Quality (2007)

The goal of this research is to determine the effects of added soybean lipoxygenase (LOX) on bread dough rheological properties and physical properties of bread loaves compared to controls, and to determine sensory attributes of bread loaves using quantitative descriptive analysis (QDA). Protein fractions were obtained through the use of isoelectric precipitation. The pH 4.8 precipitate was found to yield the greatest LOX activity when compared with other fractions (p<0.05). The addition of pH 4.8 precipitate improved rheological properties of bread dough, examined in a farinograph, when compared to the all-purpose control (p<0.05). Addition of soy flour also increased the gluten strength of all-purpose flour (p<0.05). The addition of pH 4.8 precipitate to all-purpose flour did not improve bread loaf volume or texture. Sensory panelists described pH 4.8 supplemented bread as having firmer crumb when compared with controls (p<0.05). There were slight color differences among the loaves. The crust and crumb of bread flour loaves was lighter in color than any other sample. It was concluded that the addition of pH 4.8 precipitate to all-purpose flour greatly improved the rheological properties when compared with all-purpose flour alone.

A ray launching method for radio-mobile propagation in urban area (2002)

A computer code based on digitized terrain data was developed to estimate path losses and selectivity characteristics of the urban radio channel between a mobile located in a street and a base station on the roof of a high building. The principle of the program consists in a ray launching in projection on the horizontal plane supplemented by third-dimension considerations. Some simulated results are presented and compared with actual measured data. The computed mean impulse response is always in good agreement for the first delay paths. A significant discrepancy can arise for long delay paths, but realistic features are always observed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Use of Fluorescence Resonance Energy Transfer Hybridization Probes To Evaluate Quantitative Real-Time PCR for Diagnosis of Ocular Toxoplasmosis (2004)

Toxoplasma gondii infection is an important cause of chorioretinitis in Europe and the United States. Ophthalmological examination and a good clinical response to adequate therapy mainly support ocular toxoplasmosis diagnosis. However, clinical diagnostic may be difficult in some atypical cases. In these cases, laboratory confirmation, based on detection of local specific antibodies and parasite DNA by conventional PCR, is therefore important to confirm the disease etiology. More recently, real-time PCR has been developed to improve prenatal congenital toxoplasmosis diagnosis. We therefore examined the diagnostic value of quantitative real-time PCR for the detection of T. gondii in aqueous humor samples, associated with quantification of human beta-globin to control sample quantitative quality, by using a double fluorescence resonance energy transfer hybridization probes system with a double fluorescence reading. Of the 23 the clinically toxoplasmosis suspect patients, 22 showed serological evidence of exposure to Toxoplasma; one had a serological profile indicative of active infection. The analysis of paired aqueous humor and serum samples revealed an intraocular antibody production in 9 of 23 cases (39.1%). The quantitative real-time PCR revealed positive and high parasite numbers and high Toxoplasma/human genome ratios in three cases. Furthermore, PCR was the only positive confirmatory test in two cases (11.1%). None of the patients included in the control group (n = 7) had evidence of either local specific antibody production or T. gondii DNA detection, suggesting a good relative assay specificity. On the whole, quantitative real-time PCR appears to be useful for diagnosing atypical ocular toxoplasmosis presentations.

Scalable Deep Learning Logo Detection (2018)

Existing logo detection methods usually consider a small number of logo classes and limited images per class with a strong assumption of requiring tedious object bounding box annotations, therefore not scalable to real-world dynamic applications. In this work, we tackle these challenges by exploring the webly data learning principle without the need for exhaustive manual labelling. Specifically, we propose a novel incremental learning approach, called Scalable Logo Self-co-Learning (SL^2), capable of automatically self-discovering informative training images from noisy web data for progressively improving model capability in a cross-model co-learning manner. Moreover, we introduce a very large (2,190,757 images of 194 logo classes) logo dataset "WebLogo-2M" by an automatic web data collection and processing method. Extensive comparative evaluations demonstrate the superiority of the proposed SL^2 method over the state-of-the-art strongly and weakly supervised detection models and contemporary webly data learning approaches.
