Highly Transparent, Visible-Light Photodetector Based on Oxide Semiconductors and Quantum Dots (2015)

Highly transparent phototransistors that can detect visible light have been fabricated by combining indium-gallium-zinc oxide (IGZO) and quantum dots (QDs). A wide-band-gap IGZO film was used as a transparent semiconducting channel, while small-band-gap QDs were adopted to absorb and convert visible light to an electrical signal. Typical IGZO thin-film transistors (TFTs) did not show a photocurrent with illumination of visible light. However, IGZO TFTs decorated with QDs showed enhanced photocurrent upon exposure to visible light. The device showed a responsivity of 1.35×10(4) A/W and an external quantum efficiency of 2.59×10(4) under illumination by a 635 nm laser. The origin of the increased photocurrent in the visible light was the small band gap of the QDs combined with the transparent IGZO films. Therefore, transparent phototransistors based on IGZO and QDs were fabricated and characterized in detail. The result is relevant for the development of highly transparent photodetectors that can detect visible light.
Performance of DMI and eigenspace-based beamformers (1992)

The performance of the direct matrix inversion (DMI) method for antenna arrays of arbitrary geometry is analyzed by asymptotic statistical techniques. The effects of eigenspace disturbance caused by finite samples on the output interference and noise powers are examined under the unit gain constraint in the direction of the desired signal. The results show that the performance of the DMI method is degraded mostly by the disturbed noise subspace. That suggests the use of an eigenspace-based beamformer in which the weight vector is computed by using the signal-plus-interference subspace component of the sample correlation matrix. Convergence properties of the eigenspace-based beamformer are evaluated for the cases in which the source number is known and in which it is overestimated. Theoretical analyses validated by computer simulations indicate that the eigenspace-based beamformer has faster convergence rate than the DMI method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

General bit error probability of rectangular quadrature amplitude modulation (2002)

A general closed-form expression of the exact bit error rate (BER) for an arbitrary rectangular quadrature amplitude modulation (R-QAM) with Gray code mapping is derived and analysed under an additive white Gaussian noise channel. A discussion of BER performance for maximum ratio combining diversity in Nakagami fading is also presented.
Dark Channel Prior and Global Contrast Stretching based Hybrid Defogging Image Technique (2018)

Since the foggy images undergo from low contrast and resolution due to diffusion of light and poor visibility conditions. So, Fog elimination is extremely preferred in both estimation picture making and computer vision applications. Proposed technique uses a Dark Channel Prior with contrast stretching to remove fog and improve the contrast of fog free image, respectively. Using Dark Channel Prior method one can directly take away the thickness of the haze and recover a high quality haze free image. Contrast Stretching is applied in the resulted image of dark channel prior method to improve the contrast of image. The noise that affect foggy image can also be ease by using the median low pass filter. By using this technique the visual quality and color of the foggy image can be correct effectively. Experiments are conducted on PSNR and RMSE parameters. Experimental Result shows that proposed method contains least average RMSE values and Higher PSNR values among other methods.
Dose-Intensive Response-Based Chemotherapy and Radiation Therapy for Children and Adolescents With Newly Diagnosed Intermediate-Risk Hodgkin Lymphoma: A Report From the Children's Oncology Group Study AHOD0031 (2014)

This trial demonstrated that early response assessment supported therapeutic titration (omitting radiotherapy in RERs with CR; augmenting chemotherapy in SERs with PET-positive disease). Strategies directed toward improved response assessment and risk stratification may enhance tailoring of treatment to patient characteristics and response.
Comparison of Alpha Blockers in Treatment of Premature Ejaculation: A Pilot Clinical Trial (2013)

Silodosin seems to be able to even more prevent PE. Silodosin may provide development in QoL than other alpha blocker agents. Additionally, lower systemic adverse events and more effectivity are the prominent features of silodosin in PE.This study was a pilot clinical trial. Prospectively documented 108 patients with PE were treated and were followed-up in urology outpatient clinic. All patients were divided into 5 groups according to used alpha blocker agents which were determined by simple randomization. Silodosin 4mg (Group 1, n = 21), tamsulosin hydrochloride 0.4mg (Group 2, n = 23), alfuzosin 10mg (Group 3, n = 22), terazosin 5mg (Group 4, n = 21), doksazosin mesylate 4mg (Group5, n = 21), were used for treatment. The demographic parameters of patients, pre and post treatment intravaginal ejaculation latency time (IELT), PE Profile (PEP), and QoL index were recorded and evaluated. Effectiveness of treatment was evaluated by measuring IELT. Additionally, side effects of drugs were recorded. P < 0.05 was considered statistically significant.
Private, Yet Practical, Multiparty Deep Learning (2017)

In this paper, we consider the problem of multiparty deep learning (MDL), wherein autonomous data owners jointly train accurate deep neural network models without sharing their private data. We design, implement, and evaluate ∝MDL, a new MDL paradigm built upon three primitives: asynchronous optimization, lightweight homomorphic encryption, and threshold secret sharing. Compared with prior work, ∝MDL departs in significant ways: a) besides providing explicit privacy guarantee, it retains desirable model utility, which is paramount for accuracy-critical domains; b) it provides an intuitive handle for the operator to gracefully balance model utility and training efficiency; c) moreover, it supports delicate control over communication and computational costs by offering two variants, operating under loose and tight coordination respectively, thus optimizable for given system settings (e.g., limited versus sufficient network bandwidth). Through extensive empirical evaluation using benchmark datasets and deep learning architectures, we demonstrate the efficacy of ∝MDL.
Metal ion complexes of apoferritin. Evidence for initial binding in the hydrophilic channels. (1986)

Metal binding to the iron storage protein apoferritin is the first step in the process by which iron accumulates within the protein shell. In the present study, the stoichiometry of metal binding to apoferritin in solution has been examined using the probe ions Mn(II), VO(IV), and Cd(II) in conjunction with EPR spectroscopic and cadmium ion selective electrode measurements. Binding studies were carried out with the individual ions, in competition with one another, and in competition with Fe(II), Fe(III), and Tb(III). All three probe ions show binding stoichiometries near 0.3 and 0.7 metal ion per subunit, close to the theoretically predicted values of 0.33 and 0.67 for the binding of one and two metal ions, respectively, per three subunits. These results in conjunction with other data are consistent with the binding of one, and possibly two, metal ions within each of the eight hydrophilic channels which are located on 3-fold axes leading to the interior of the protein. Pairs of cadmium binding sites have been located in these channels by x-ray crystallography (Rice, D. W., Ford, G. C., White, J. L., Smith, J. M. A., and Harrison, P. M. (1983) Adv. Inorg. Biochem. 5, 39-49). The possibility that some metal binding occurs elsewhere on the protein is not precluded by the present data, however. In competition experiments between various metal ions, approximately 0.3 metal ion per subunit is readily displaced implying common binding sites in the channels for all of them. The stoichiometry of Mn(II) displacement by Fe(II) is less clear. Oxidation of Fe(II) to Fe(III) by molecular oxygen in the presence of Mn(II) regenerates some Mn(II) binding on the protein, suggesting migration of iron(III) to other protein sites, or perhaps to core.
Gamma interferon enhances macrophage transcription of the tumor necrosis factor/cachectin, interleukin 1, and urokinase genes, which are controlled by short-lived repressors. (1986)

Exposure of mouse resident and thioglycollate-elicited peritoneal macrophages to IFN-gamma leads to a marked increase in the TNF-alpha (tumor necrosis factor/cachectin), IL-1 and u-PA (urokinase-type plasminogen activator) mRNA levels. Nuclear run-on experiments show that IFN-gamma acts by enhancing the transcription of these three genes. Transcription of these three genes is also rapidly and transiently induced by cycloheximide, an inhibitor of protein synthesis, indicating that they are under the control of short-lived repressors.
Effect of Developmental Age or Time after Transplantation on Sertoli Cell Number and Testicular Size in Inbred Fischer Rats1 (1996)

The objectives were to establish the developmental age of Fischer rats at which the Sertoli cell number is stabilized, to establish the normal reference plateau number of Sertoli cells for evaluation of testes after transplantation, and to determine whether the developmental pattern establishing Sertoli cell proliferation and stability are similar between intact and transplanted testes. Sertoli cell number was determined at ages 1--120 days in intact rats and at various times (10-90 days) after transplantation of prenatal or neonatal tests. Tests were fixed by vascular perfusion or by immersion with 2% glutaraldehyde and and immersion in 1% osmium and were embedded in Epon 812. Sections and serial sections were cut at 0.5 micrometer to determine the Sertoli cell nuclei volume density and the volume of an individual Sertoli cell nucleus by brightfield microscopy or at 20 micrometers to determine the maximum height and width of nuclei. A correction factor was calculated for intact (0.663 +/- 0.025) or for transplanted (0.558 +/- 0.029) testes to determine the volume of a single Sertoli cell nucleus from height and width measurements. In intact testes, Sertoli cell numbers significantly increased to Day 20 but were not different between 15 and 90 days. Sertoli cell number in prenatal or neonatal transplanted testes increased to 20 or 30 days posttransplantation and then stabilized to Day 60 or 90. There was no difference in the plateau number of Sertoli cells per rat between prenatal and neonatal testes. Sertoli cells in 10-day- and 30-day-transplanted testes incorporated 3H-thymidine when placed in culture. A few tubules had complete spermatogenesis at 90 days posttransplantation, indicating that Sertoli cells in some of these tubules were functional. Leydig cell structure appeared to be normal. Leukocytic infiltration of testes was not observed in intact rats or in rats receiving neonatal testes. Although transplanted testes showed a delay in reaching the plateau value for Sertoli cell number per testis and although the value reached was lower, the developmental pattern of Sertoli cell proliferation in transplanted testes was similar to that in intact rats.
The nuclear membranes in hypertrophied human cardiac muscle cells. (1975)

Nuclear membranes of cardiac muscle cells were studied in 134 patients with cardiac hypertrophy of various causes. Abnormalities observed consisted of: a) increased foldings and convolutions; b) nuclear pseudoinclusions formed by cytoplasmic organelles protruding into saccular invaginations of the nuclear membranes, and c) intranuclear tubules. The increased foldings and convolutions of the nuclear membranes and the nuclear pseudoinclusions appear to result from synthesis of nuclear membranes in excess of that needed to accommodate the increase in nuclear volume which occurs in hypertrophy. Intranuclear tubules were found in 6 patients and consisted of tubular invaginations, 400 to 650 A in diameter, of the inner nuclear membranes into the nucleoplasm. Some of these tubules were straight and cylindrical, and were associated with a peripheral layer of marginated chromatin; others were not associated with chromatin, appeared coiled and followed irregular courses. Intranuclear tubules in cardiac muscle cells probably represent an extreme cellular response to the stimulus of hypertrophy.

Poly(A·A·U) Triple Helix Formation Promoted by Porphyrin Assembly (1996)

A multicomponent molecular recognition process leads to a self‐assembled “quaternary” supramolecular complex formed from porphyrins and an “unusual” poly(A·A·U) triple helix. The formation of this superstructure is promoted by porphyrin aggregation and a number of recognition processes (Watson‐Crick and Hoogsteen pairing, coulombic interactions, and stacking interactions).
Trends in preterm labor. (1992)

Preterm birth has been identified by the National Commission to Prevent Infant Mortality (1988) as the primary cause of the increased infant mortality rate in the United States. An analysis of what is currently known about four areas of preterm labor including (1) definition and causes, (2) identification of patients at risk, (3) management techniques, and (4) use of patient education in labor is presented in this paper. Preterm labor is defined as uterine contractions that occur between 20 and 37 weeks' gestation with progressive cervical dilatation or effacement or both. Directions for future research are discussed.
Depression and increased risk of mortality in the nursing home patient. (1993)

Depression is a common clinical syndrome in the elderly, often resulting in attempted and/or successful suicide. Within the community and in a wide range of medical care settings, including nursing homes, depression is often undiagnosed and untreated. In a 1-year investigation that included 454 new patient admissions to eight Baltimore area nursing home facilities, major depressive disorder occurred in 12.6% of patients; an additional 18.1% had depressive symptoms. Most cases of depression were unrecognized and therefore untreated by nursing home physicians. Major depressive disorder was found to be an independent risk factor for mortality that increased the likelihood of death by 59% in the first year after diagnosis. Because new federal regulations now mandate the assessment of depression in nursing home patients, improved diagnosis and therapy (and therefore reduced disability and mortality) may be expected in the future.
Consciousness of the Exotic and Exotic Consciousness in Chateaubriand (2010)

Chateaubriand's many works set in exotic places speak in several voices: that of l'enchanteur , the spell-binding descriptive prose poet and rhetorician; of the scholar drawing on accounts by travelers and historians; and of the covert autobiographer. Less attention has been paid to Chateaubriand's representations of the voices of the ethnic other, particularly, of Native Americans. This essay examines instances when his depiction of Native American discourse is patently ventriloquized, distorted, or subverted. Nevertheless - if only through psychic projection and fantasized identifi cation - Chateaubriand's apocalyptic vision conveys real affinities between the experience of French aristocrats under the Revolution, and tribes facing colonization, expropriation of their lands, and genocide.
Laboratory tests to exclude IgA deficiency in the investigation of suspected anti‐IgA transfusion reactions (1993)

Four methods were compared as to their suitability for excluding IgA deficiency in the investigation of suspected anti-IgA transfusion reactions. The methods were radial immunodiffusion, passive hemagglutination inhibition, sandwich enzyme-linked immunosorbent assay, and membrane enzyme immunoassay. Parallel testing was performed on sera from 40 patients or blood donors previously found to have anti-IgA and low or undetectable levels of IgA. All test methods identified the 40 sera as having abnormally low IgA levels. The membrane enzyme immunoassay required 10 minutes or less for testing, as compared to 3 hours for passive hemagglutination inhibition, 4 hours for sandwich enzyme-linked immunosorbent assay, and 48 hours for radial immunodiffusion. The membrane enzyme immunoassay offers the potential for a rapid, instrument-free screen of IgA levels and therefore may be useful in identifying those patients with suspected anti-IgA anaphylactic transfusion reactions who are not IgA deficient and do not require IgA-deficient blood components for additional transfusions.
Different fabrication methods of out-of-plane polymer hollow needle arrays and their variations (2007)

We demonstrate, in this paper, different methods for the fabrication of various out-of-plane hollow micro needle arrays through back side exposure. We validated the back side exposure to be capable of producing microstructures with taper angles experimentally. Then we found that the taper angles can be adjusted by changing the distance between the photo mask absorber and the photoresist. Solid micro needles can be fabricated by properly calculating the side wall tilting angle and the thickness of the photo resist, while hollow micro needles can be realized by one lithography step through appropriate combination of different back side exposure methods. In this paper, we also demonstrate the capability of fabricating a micro needle array on a flexible membrane for further medical applications.
Method for improving the accuracy of quantitative cerebral perfusion imaging (2005)

The addition of a CBV(SS) measurement to an STD measurement of cerebral perfusion improves the accuracy of CBV and CBF measurements. The method may prove useful for assessing patients suffering from acute stroke.
AEROSPACE APPLICATIONS OF CASE-BASED REASONING (1990)

Case-Based Reasoning (CBR) has been proposed as an expert system approach that may overcome a number of limitations of standard rule-based expert systems (DARPA-sponsored Workshops, Pensacola, FL, 1988, 1989). Under the sponsorship of DARPA, a generic CBR shell has been developed that runs on a Zenith 386 PC with expanded memory.
Isolation of Hormone-Producing Clonal Lines of Human Choriocarcinoma<sup>1</sup> (1971)

Six clonal lines of human choriocarcinoma have been established from a tumor previously adapted to passage in the hamster cheek pouch. All clones have continued to produce chorionic gonadotropin (CG) for over 2 yr. The rates of hormone secretion and growth differed among the clonal lines. In one clone, cell count and CG production showed log increases and plateau phases, but the log phase of CG synthesis occurred as the rate of cell replication slowed. Accordingly, CG production per cell increased progressively with time. These functional cell lines provide systems for the examination of many aspects of placental physiology and biology.
Multivariate Turbofan Engine Control for Full Flight Envelope Operation (1989)

The design of a full flight envelope nonlinear multivariable controller is described for a single-bypass variable-cycle jet engine. The nonlinear controller is obtained by using appropriate engine corrected parameters to schedule multivariable linear compensator gains designed at selected operating points of the flight envelope. The KQ (K-matrix compensator, Q-desired response) multivariable control design technique is used to design the compensators using linear state-space models obtained from a detailed nonlinear aerothermo model. The controller is implemented in the detailed nonlinear aerothermo model. The paper describes an example KQ compensator design, the corrected-parameter gain scheduling approach, and controller performance validation by nonlinear simulation. Computer simulations for sea-level static, and supersonic operating points are included to show the closed-loop transient performance in the presence of an acceleration fuel schedule.
CENTELLA ASIATICA (L.): A PLANT WITH IMMENSE MEDICINAL POTENTIAL BUT THREATENED (2010)

Centella asiatica (L.) is a perennial, creeper, faintly aromatic and a valuable medicinal herb of both Old World and the New World. It is distributed throughout tropical and subtropical regions of World such as India, China, Nepal, Madagascar, Srilanka and Indonesia etc. The requirement of Centella asiatica is now met from natural population, leading to their gradual depletion and thus followed by its placement in the list of threatened species as mentioned by IUCN. Much of the ancient and contemporary lore surrounding this plant with its chemistry and pharmacology related to efficacy of both herbal preparations and chemical isolates are justified on the basis of experimental evidences. This paper provides its immense importance as economic plant with medicinal value as well as brief information of its products in the market launched, showing its dependability.
