An autocorrelation pitch detector and voicing decision with confidence measures developed for noise-corrupted speech (1991)

The authors describe an integrated speech feature extraction method consisting of: (1) a pitch detector; (2) a voicing decision to correctly partition speech into voiced and unvoiced intervals; (3) a confidence measure which reflects the probabilistic accuracy of the voicing decision; (4) a confidence measure which reflects the expected deviation of the pitch estimate from the true pitch and the probabilistic accuracy of this deviation; and (5) smoothing techniques for the pitch detector, the voicing decision, and the two confidence measures. The focus of their research is on voiced and unvoiced speech corrupted by high levels of white noise. The voicing decision and the confidence measures are developed by observing the behavior of three features derived from the autocorrelation function and experimentally fitting curves to the data. This integrated set of algorithms is statistically analyzed for speech at seven signal-to-noise ratios.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Split-plane shadow volumes (2005)

We present a novel method for rendering shadow volumes. The core idea of the method is to locally choose between Z-pass and Z-fail algorithms on a per-tile basis. The choice is made by comparing the contents of the low-resolution depth buffer against an automatically constructed split plane. We show that this reduces the number of stencil updates substantially without affecting the resulting shadows. We outline a simple and efficient hardware implementation that enables the early tile culling stages to reject considerably more pixels than with shadow volume optimizations currently available in the hardware.

In the present study, CdZnS and Co (3%): CdZnS nanoparticles (NPs) have been synthesized via wet chemical method at room temperature using 1-thioglycerol as a capping agent. The incident photon-to-current conversion efficiency (IPCE) measurement has been carried out for Co (5%): CdZnS for the first time in this study. The results show that Co (3%): CdZnS can be utilized as sensitizers to improve the performance of solar cells. In addition to the photovoltaic properties; structural, optical and morphological properties of Co (3%): CdZnS NPs have been investigated. The results indicate that Co (3%): CdZnS NPs can be suitable material for photovoltaic applications.
Private Stream Aggregation Revisited (2015)

In this work, we investigate the problem of private statistical analysis in the distributed and semi-honest setting. In particular, we study properties of Private Stream Aggregation schemes, first introduced by Shi et al. \cite{2}. These are computationally secure protocols for the aggregation of data in a network and have a very small communication cost. We show that such schemes can be built upon any key-homomorphic \textit{weak} pseudo-random function. Thus, in contrast to the aforementioned work, our security definition can be achieved in the \textit{standard model}. In addition, we give a computationally efficient instantiation of this protocol based on the Decisional Diffie-Hellman problem. Moreover, we show that every mechanism which preserves $(ε,δ)$-differential privacy provides \textit{computational} $(ε,δ)$-differential privacy when it is executed through a Private Stream Aggregation scheme. Finally, we introduce a novel perturbation mechanism based on the \textit{Skellam distribution} that is suited for the distributed setting, and compare its performances with those of previous solutions.
N-(4-Anilinophenyl)-Methacrylamide, a Polymerizable Amine Antioxidant: Synthesis, Copolymerization, Copolymer Properties, and Performance (1989)

Abstract In conclusion, we have demonstrated that N (4-anilinophenyl)-methacrylamide (APMA) is a readily polymerizable, nonstaining amine antioxidant molecule that can be incorporated into free-radical emulsion polymerization recipes by a variety of techniques. Furthermore, we have also demonstrated that the polymer-bound APMA's effectiveness can be greatly enhanced in gum or cured rubber when it is used in conjunction with either free or bound sulfur-containing secondary antioxidants (synergists). Superior performance was demonstrated for the polymer-bound antioxidant systems using oxygen absorption, DSC, and aged (extracted) physical property retention techniques.
Variable gain current mirror for high-speed applications (2007)

This paper presents a new high speed current mirror with continuous gain adjustment. Based on this current mirror, a variable gain current amplifier is designed in 0.18µm CMOS technology. The current gain of the amplifier can be continuously varied from 0dB to 20dB while the bandwidth of the circuit remains above 100MHz. The circuit consumes 0.9mW from 1.5V supply.
RNA interference-based resistance in transgenic tomato plants against Tomato yellow leaf curl virus-Oman (TYLCV-OM) and its associated betasatellite (2015)

These results show that RNAi can be used to develop resistance against geminiviruses in tomato. The resistance in this case is not immunity but does reduce the severity of infections and virus titer. Also, the betasatellite may compromise resistance, increasing the proportion of plants which ultimately show symptoms.
Regioselective addition of alkyl phosphites on 6-(aryliminomethyl)-furobenzopyran-5-one derivatives (2012)

Aim Trialkyl phosphites 2a,b attack 6-(aryliminomethyl)furobenzopyran-5-ones 1a–e regiospecifically at the carbon–carbon double bond of the γ-pyrone ring to yield new 1,2-addition phosphonate products for which structures 3a–e have been respectively assigned. 
Methods The alkyl phosphites 2a,b attacked the monoanils 1a–e at the azomethine carbon of the C=N bond to yield corresponding phosphonate adducts 5a–e when reactions were carried out in the presence of a controlled amount of acetic acid. Phosphonates 5a–e could also be obtained by the reaction of dialkyl phosphites 4a,b with anils 1a–e. Structures of the new phosphonates 3a–e were elucidated by elemental analyses as well as spectroscopic methods. The 1 H and 13 C nuclear magnetic resonance and infrared measurements were helpful tools in confirming the structures of the new products. 
Results and conclusion The insecticidal activities of phosphonates 3a–e and their respective regioisomers 5a–e against adult Aphis gossypii (Glover), which infest cotton crops, were determined. The structure–activity relationship has been discussed.
A Type-C Virus in Human Rhabdomyosarcoma Cells After Inoculation into NIH Swiss Mice Treated with Antithymocyte Serum (1973)

A type-C RNA virus has been isolated that replicates readily in human and other primate cells. It was obtained from a human rhabdomyosarcoma cell (RD) that had been serially transplanted in immunosuppressed NIH Swiss mice, a strain of mouse from which infectious type-C virus has not been isolated. Various other human tumor cells, similarly transplanted, remained free of overt type-C virus expression. The virus growing in the RD cells, AT-124, has a group-specific antigen and an RNA-dependent DNA polymerase immunologically related to murine type-C viruses, but a host range similar to that of the RD-114 virus. The new isolate is either a previously undescribed, endogenous type-C virus from NIH Swiss mice or a recombinant with both mouse and human type-C genetic information.
Silicon photomultiplier: Detector for highly sensitive detection of fluorescence signals (2008)

We demonstrate use of silicon photomultipliers (SiPMs) in single photon counting mode for detection of very weak laser induced fluorescence (LIF). Detection of LIF in DNA-sequencing has been performed with three different commercially available SiPMs.
Thermal decomposition of 3,3-dimethylcyclobutanone (1977)

The thermal decomposition of 3,3-dimethylcyclobutanone in the gas phase in the temperature range 261–313 °C has been found to be homogeneous and to obey first-order kinetics; the rate constants fit the Arrhenius equation (i). log k/s–1= 14.573 ± 0.078 –(192.750 ± 840) J mol–1/RT In10 (i). The results have been interpreted as showing strong support for a quasi-zwitterionic puckered ring activated complex.
Acoustic agglomeration of power plant fly ash for environmental and hot gas cleanup (1987)

Emission of small particulates from coal-fired power plants in the range of 0.5 to 5 μ results in particularly serious injury to the human respiratory system. Currently used environmental cleanup devices in power plants such as bag houses, electrostatic precipitators, wet scrubbers, and others are very efficient in removing particulates which are larger than about 2 μ in size, leaving by far the majority of these tiny particulates to be emitted into the air environment. Current regulations for effluent cleanup emphasize the mass removal without any attention to the particulate size. Acoustic agglomeration is a means of causing these tiny particulates to collide with one another, adhere, and thereby result in the formation of larger particles, thus removing the tiny particulates from the aerosol stream. In this manner, the efficiency of particle removal of the conventional removal devices can be substantially enhanced. This paper introduces some of the fundamental aspects of acoustic agglomeration theory and practice and presents some of the results of recent studies.
Nuclear Technology Programs semiannual progress report, October 1986--March 1987 (1988)

This document reports on the work done by the Nuclear Technology Programs of the Chemical Technology Division, Argonne National Laboratory, in the period October 1986--March 1987. Work in applied physical chemistry included investigations into the processes that control the release and transport of fission products under accident-like conditions, the thermophysical properties of metal fuel and blanket materials of the Integral Fast Reactor, and the properties of selected materials in environments simulating those of fusion energy systems. In the area of separation science and technology, the bulk of the effort is concerned with developing and implementing processes for the removal and concentration of actinides from waste streams contaminated by transuranic elements. Another effort is concerned with examining the feasibility of substituting low-energy for high-enriched uranium in the production of fission product /sup 99/Mo. In the area of waste management, investigations are underway on the performance of materials in projected nuclear repository conditions to provide input to the licensing of the nation's high-level waste repositories.

Human MiniPromoters for ocular-rAAV expression in ON bipolar, cone, corneal, endothelial, Müller glial, and PAX6 cells (2021)

Abstract Small and cell-type restricted promoters are important tools for basic and preclinical research, and clinical delivery of gene therapies. In clinical gene therapy, ophthalmic trials have been leading the field, with over 50% of ocular clinical trials using promoters that restrict expression based on cell type. Here, 19 human DNA MiniPromoters were bioinformatically designed for rAAV, tested by neonatal intravenous delivery in mouse, and successful MiniPromoters went on to be tested by intravitreal, subretinal, intrastromal, and/or intravenous delivery in adult mouse. We present promoter development as an overview for each cell type, but only show results in detail for the recommended MiniPromoters: Ple265 and Ple341 ( PCP2 ) ON bipolar, Ple349 ( PDE6H ) cone, Ple253 ( PITX3 ) corneal stroma, Ple32 ( CLDN5 ) endothelial cells of the blood–retina barrier, Ple316 ( NR2E1 ) Müller glia, and Ple331 ( PAX6 ) PAX6 positive. Overall, we present a resource of new, redesigned, and improved MiniPromoters for ocular gene therapy that range in size from 784 to 2484 bp, and from weaker, equal, or stronger in strength relative to the ubiquitous control promoter smCBA. All MiniPromoters will be useful for therapies involving small regulatory RNA and DNA, and proteins ranging from 517 to 1084 amino acids, representing 62.9–90.2% of human proteins.
Regression tree classification for activity prediction in smart homes (2014)

The growing number of older adults in the population has created an increasing need for health-assistive systems, including prompting interventions to provide activity reminders. In this paper, we present a new regression-tree-based activity forecasting algorithm to predict the occurrence of future activities for prompting initiation of such activities. This automated algorithm extracts high-level features from sensor events and inputs these features to a machine learning algorithm which forecasts when a target activity will next occur. We compare this system to a standard linear regression classification using real data from smart homes. The forecasting algorithm is shown to provide lower error rates over the linear regression model.
High quality rendering using ray tracing and photon mapping (2007)

Ray tracing and photon mapping provide a practical way of efficiently simulating global illumination including interreflections, caustics, color bleeding, participating media and subsurface scattering in scenes with complicated geometry and advanced material models.
Proposed System for Ultrafast Computed Tomography (1977)

Construction of a new ultrafast scanner system suitable for dynamic computed tomography is now under consideration, with development soon to begin. This system will be characterized by an electronically controlled X-ray generator with wide angle double diffraction, which will permit transverse axial images to be taken in times as short as 0.01 second.
Immune and Inflammatory Mechanisms of Atherosclerosis (2009)

Atherosclerosis is an inflammatory disease of the wall of large- and medium-sized arteries that is precipitated by elevated levels of low-density lipoprotein (LDL) cholesterol in the blood. Although dendritic cells (DCs) and lymphocytes are found in the adventitia of normal arteries, their number is greatly expanded and their distribution changed in human and mouse atherosclerotic arteries. Macrophages, DCs, foam cells, lymphocytes, and other inflammatory cells are found in the intimal atherosclerotic lesions. Beneath these lesions, adventitial leukocytes organize in clusters that resemble tertiary lymphoid tissues. Experimental interventions can reduce the number of available blood monocytes, from which macrophages and most DCs and foam cells are derived, and reduce atherosclerotic lesion burden without altering blood lipids. Under proatherogenic conditions, nitric oxide production from endothelial cells is reduced and the burden of reactive oxygen species (ROS) and advanced glycation end products (AGE) is increased. Incapacitating ROS-generating NADPH oxidase or the receptor for AGE (RAGE) has beneficial effects. Targeting inflammatory adhesion molecules also reduces atherosclerosis. Conversely, removing or blocking IL-10 or TGF-beta accelerates atherosclerosis. Regulatory T cells and B1 cells secreting natural antibodies are atheroprotective. This review summarizes our current understanding of inflammatory and immune mechanisms in atherosclerosis.
Conservation of the Biotin Regulon and the BirA Regulatory Signal in Eubacteria and Archaea (2002)

Biotin is a necessary cofactor of numerous biotin-dependent carboxylases in a variety of microorganisms. The strict control of biotin biosynthesis in Escherichia coli is mediated by the bifunctional BirA protein, which acts both as a biotin-protein ligase and as a transcriptional repressor of the biotin operon. Little is known about regulation of biotin biosynthesis in other bacteria. Using comparative genomics and phylogenetic analysis, we describe the biotin biosynthetic pathway and the BirA regulon in most available bacterial genomes. Existence of an N-terminal DNA-binding domain in BirA strictly correlates with the presence of putative BirA-binding sites upstream of biotin operons. The predicted BirA-binding sites are well conserved among various eubacterial and archaeal genomes. The possible role of the hypothetical genes bioY and yhfS-yhfT, newly identified members of the BirA regulon, in the biotin metabolism is discussed. Based on analysis of co-occurrence of the biotin biosynthetic genes and bioY in complete genomes, we predict involvement of the transmembrane protein BioY in biotin transport. Various nonorthologous substitutes of the bioC-coupled gene bioH from E. coli, observed in several genomes, possibly represent the existence of different pathways for pimeloyl-CoA biosynthesis. Another interesting result of analysis of operon structures and BirA sites is that some biotin-dependent carboxylases from Rhodobacter capsulatus, actinomycetes, and archaea are possibly coregulated with BirA. BirA is the first example of a transcriptional regulator with a conserved binding signal in eubacteria and archaea.
Molecular biology of myocardial hypertrophy and failure: gene expression and trophic signaling. (1995)

Pressure-overload cardiac hypertrophy is associated with the re-expression of an ensemble of genes representative of embryonic myocardium, whose protein products modulate myocardial function. Regulation of cardiac-specific gene expression in end-stage myocardial disease in humans implies a pathophysiologic role for altered gene expression in the progression from compensatory hypertrophy to decompensated heart failure. The molecular signals that transduce load into a hypertrophic cardiac myocyte phenotype involve mechanical deformation and the local myocardial production of trophic factors, including angiotensin II, and transforming and fibroblast growth factors. Growth factors provoke a pattern of gene expression in cultured cardiac myocytes resembling that seen in pressure overload in vivo, in keeping with an autocrine or paracrine model of hypertrophy. Moreover, growth factor stimulation and pressure-overload hypertrophy share intracellular signaling pathways, including the activation of nuclear proteins encoded by cellular oncogenes. Elucidation of these signaling pathways may provide new therapeutic targets for the treatment of cardiac muscle disease that overcomes the limitations of currently available strategies.

[TRANSFORMATION OF HEMOPOIETIC CELLS OF TRANSPLANTED ALLOGENOUS BONE MARROW INTO IMMUNOLOGICALLY COMPETENT CELLS IN IRRADIATED DOGS]. (1963)

In experiments on dogs subjected to superlethal irradiation (1000 r), it was demonstrated that allogenous bone marrow transplantation does not produce a therapeutic effects inasmuch as normal hemopoiesis of the transplant is preserved only for 3--4 days. Starting from the 5th6th day there takes place transformation of hemopoietic cells into immunologically competent cells, which are the morphological basis of the transplant against host reaction. Transformation of hemopoietic cells (hemocytoblasts) into immunologically competent cells (lymphocytes) occurs via a number of transitional hyperbasophilic forms. of the type of peculiar hemocytoblast, lymphoblast, and prolymphocyte. The transformation of hemopoiesis is associated with the antigenic differences of the donor and recipient, since during repopulation of the bone marrow from the screened extremities in active proliferation no hyperbasophilic cells are formed and the myeloid hemopoiesis is preserved. The formation therefrom of hyperbasophilic cells and lymphocytes is due to transforination of hemocytoblasts and not immunologically coinpetent cells of the bone marrow, for this process was not as marked during transplantation of a suspension of lymphoid cells from the lymph nodes and spleen.

Processing Techniques and Applications of Positive Temperature Coefficient Thermistors (1963)

Thermistors with positive temperature characteristics of resistance have been recently developed. Their distinguished temperature characteristics, being divided into two groups--type SW and TC--have various application fields in electronic and electrical engineering. The paper describes and surveys the processing techniques of major importance, the fundamental characteristics of this component, and design criteria for the desired component. Various uses of the component, as a thermal controller, a current limiter, a current stabilizer, a temperature compensator, etc., are explained to serve as a guide to other applications.
