Implementation of Polyphase Channelizers for Multirate Signal Analysis (2006)

Polyphase discrete-Fourier transform (DFT) filter banks are used in a wide variety of applications involving the channelization and analysis of multi-component signals. Of particular interest are oversampled architectures that enable high-fidelity demodulation and signal processing of channelized signals. In this paper, we examine architectures of polyphase DFT filter banks that are suitable for field programmable gate array (FPGA) implementation and discuss implementation issues that arise in high speed, realtime applications.
Silicon nanoparticles mitigate oxidative stress of in vitro-derived banana (Musa acuminata ‘Grand Nain’) under simulated water deficit or salinity stress (2020)

Climate change and rising sea levels increasingly threaten agriculture, especially in the coastal regions. Banana cultivars, especially the Cavendish clones, are sensitive to salinity stresses, which results in decreased production. In the current study, we evaluated the water deficit stress remediating effects of silicon nanoparticles (SiO2NPs) on micropropagated banana cv. “Grand Nain” - either under in vitro conditions in the laboratory or ex vitro in the greenhouse. In vitro water deficit was induced with polyethylene glycol (PEG-8000). Addition of in vitro SiO2NPs enhanced shoot growth and chlorophyll content. Malondialdehyde content (MDA) and electrolyte leakage (EL) were reduced in 3% PEG-stressed plants following the addition of the 150 mg/l SiO2NPs (38.73 nmole and 4.93%) compared with the control plants (51.67 nmole and 5.76%). In the greenhouse study, plants under salt and water deficit treatments were sprayed with SiO2NPs at (0, 200, 400 and 600 mg/l). Under salinity stress conditions, SiO2NPs improved photosynthesis as the stressed plants had similar chlorophyll content as control unstressed plants (23.33). SiO2NPs at 400 mg/l application increased K+ level (10.54%) and decreased Na+ levels (1.17%). Under simulated water deficit stress conditions, 600 mg/l SiO2NPs significantly increased K+ and K+/Na+ percent (10.37 and 14.40%) along with improvement in chlorophyll content index at all levels of SiO2NPs application. The overall results revealed that SiO2NPs application can improve chlorophyll content, induce K+ uptake, modulate Na+ levels and decrease cell wall damage in the treated plants comparing to the untreated plants under abiotic stress. Our results suggest that the application of SiO2NPs can help maintain plant integrity in the banana cultivar ‘Grand Nain’ under simulated abiotic stress.
INCREASED PHOSPHOLIPID MASS WITH DECREASED ARACHIDONOYL MOLECULAR SPECIES IS ASSOCIATED WITH DECREASED EICOSANOID SYNTHESIS AND INCREASED TUMOR NECROSIS FACTOR SYNTHESIS BY THIOGLYCOLLATE-ELICITED RAT PERITONEAL MACROPHAGES (1995)

Because the activation state of macrophages may alter their response to endotoxin, we compared phospholipid arachidonic acid content, and synthesis of eicosanoids and tumor necrosis factor by resident and thioglycollate-elicited rat peritoneal macrophages. Thioglycollate elicitation increased macrophage phospholipid mass twofold, increased the relative percentages of 16:0-20:4 diacylglycerophosphocholine (PtdCho) and 18:0-20:4 diacylglycerophosphoethanolamine (PtdEtn), and decreased the relative percentages of 18:0-20:4 alkenylacylglycerophosphoethanolamine (PlsEtn) and 18:0-20:4 alkylacylglycerophosphocholine (PakCho) compared with resident peritoneal macrophages. Thioglycollate-elicited macrophages synthesized significantly less thromboxane B2, 6-keto-prostaglandin F1 alpha, and prostaglandin E2 and more tumor necrosis factor (TNF) activity in response to both endotoxin and A23187 than did resident macrophages. These results suggest that thioglycollate elicitation decreases specific arachidonic acid-containing molecular species in PlsEtn and PakCho, which may, in part, explain the decrease in eicosanoid and increase in TNF synthesis by thioglycollate-elicited macrophages. The differences between resident and thioglycollate-elicited macrophages in the synthesis of the eicosanoids and TNF activity was not altered by increasing either the concentration of either stimulus or the incubation time.
The Interaction of HIV-1 with the Host Factors (2005)

Human immunodeficiency virus type 1 (HIV-1) is a causative agent of acquired immunodeficiency syndrome (AIDS) in humans. In the last decade, the functions of HIV-1-encoded genes have been intensively studied. These studies have contributed to the development of the effective anti-AIDS drugs directing against the HIV-1-encoded enzymes, namely reverse transcriptase and protease. However, even the combination of these drugs is not sufficient enough to stop the progression of AIDS partly due to the emergence of drug-resistant HIV-1 mutants as well as the severe side effects. Understanding the molecular mechanisms by which cellular factors support the efficient replication of HIV-1 should contribute to develop means to control the progression of AIDS. This field is now expanding rapidly. Here we review the host factors involved in the replication of HIV-1 and highlight some findings that have a substantial impact on the retroviral research.
Design and Application: Slurry Pump Technology (2005)

Slurry Pumps are used throughout the world for the Transportation of Solids in Coal, Copper Iron-Ore, Phosphate and other Mines. They are also used in Dredges cleaning Waterways in Sand and Gravel, and in Phosphoric Acid and Alumina Plants. About $500 million worth of slurry pumps and replacement parts are estimated to be produced every year. Slurry pumps are similar to water pumps so a lot of the available water pump technology can still be used. When it comes to determining pipeline velocities and heads, and the effect of slurries on performance, however, different technologies are found to be necessary. In designing for, and predicting pump wear performance, for example, special numerical modeling tools are found to be necessary. Pump system evaluations require a completely different approach. Cost of ownership calculations for slurry pumps must for example, consider wear parts life as they can be 50% of the total. When the whole system is considered, it needs to be in terms of the cost of transporting a number of tons of dry solids a given distance. Not water transported or pump efficiency. The writers in this presentation provides an outline of the different technologies involved in the design and application of centrifugal slurry pumps, how these are applied, and the insight they provide.
Linkage disequilibrium between cystic fibrosis and linked DNA polymorphisms in Italian families: a collaborative study. (1988)

The locus D7S23 includes a CpG-enriched methylation-free island that maps midway between the markers J3.11 and met and is genetically very close to the mutation causing cystic fibrosis (CF). We have studied the linkage disequilibrium between four polymorphic markers from this locus (KM.19, CS.7, XV-2c, and PT-3) and the CF mutation (CF) in 127 Italian families. Strong linkage disequilibrium is found between KM.19, CS.7, and CF, and weaker but significant disequilibrium is found between XV-2c, PT-3, and CF. The disequilibrium between markers and CF for the Italian population provides additional information on the origin and homogeneity of the CF defect. This panel of probes is sufficiently informative to permit accurate prenatal diagnosis of CF in most families with an affected person, and the disequilibrium also allows indirect carrier detection/exclusion in some cases.
Bacillus pumilus strains with inactivated genes of extracellular serine proteinases (2013)

Two Bacillus pumilus strains with inactivated genes of extracellular serine proteinases (subtilisin-like proteinase and glutamyl endopeptidase) were obtained. Inactivation of the gseBp and aprBp genes resulted in an increase in cell size, changed colony shape, and more rapid cell lysis that started during the growth retardation phase. Protease-deficient stains partially changed the ability to decompose carbohydrates (sugars), reduced resistance to variations in temperature of cultivation, and did not respond to the fluctuations of phosphate concentration in the medium. Proteinases gene disruption resulted in alteration of hydrolases secretion level by these bacteria.
Assessing Flow Response of Self-compacting Mortar by Taguchi Method and ANOVA Interaction (2012)

Self-compacting mortar (SCM) is a new generation product and has prospective use as an independent material as well as an integral constituent of self-compacting concrete (SCC). In this paper the flow response of self-compacting mortar is assessed by Taguchi method and ANOVA interaction. Effect of powder material and super-plasticizer on the relative flow index of fresh SCM is evaluated by mortar trial test designed by Taguchi method of optimization. An ANOVA interaction analysis is performed to comprehend the interaction of the factors and their effect on quality characteristic. The relative significance level of powder material and super-plasticizer in governing the flow characteristic is discussed. A modified approach is proposed by incorporation of the error balancing property of statistical central tendency and the assumption of non- variance of mean. Construing contribution of mean, sample size and relative error to Signal to Noise Ratio provides limits of deviations of the same.
Depth absorbed dose distributions for electrons (1978)

The influence of energy spread on the depth dose distribution of high energy electrons, which is complicated by the different methods used in the specification of electron beam energy, is discussed.
Papillae formation in parathyroid adenoma. A source of possible diagnostic error. (1988)

Parathyroid adenomas, the most common cause of hyperparathyroidism, display diverse histologic patterns. The majority of adenomas form solid masses or show nodular, trabecular, and acinar patterns. In a four-year review of data on 103 surgically resected parathyroid adenomas, we encountered only a single case that showed papillae formation. We report this case to illustrate occurrence of this unusual histologic pattern that might create a diagnostic problem.

Comparative study of single and multiemissive layers in inverted white organic light-emitting devices (2006)

The authors have fabricated and compared highly efficient inverted white organic light-emitting devices (WOLEDs) with a single emission layer (SEL) and with a multiemission layer (MEL). The efficiency levels of the WOLEDs with a SEL and a MEL achieved 13.0cd∕A, 10.6lm∕W and 11.3cd∕A, 7.3lm∕W, respectively. The projected half lifetime of a SEL device under an initial luminance of 400cd∕m2 is expected to be over 34000h, which is five times better than that of a MEL device of 6350h. The Commission International de l’Eclairage coordinates of a SEL device are not affected by aging.
Pyruvate dehydrogenase kinase 1 is essential for transplantable mouse bone marrow hematopoietic stem cell and progenitor function (2017)

Our study demonstrates that PDK1 has broad effects in hematopoiesis and is a critical factor for engraftment of both HSCs and multipotent progenitors upon transplantation to recipient mice. While Pdk1 was a robust hypoxia-inducible gene mediated by HIF-1α in vitro, we could not find evidence of any in vivo links between Pdk1 and HIF-1α.
Formation and applications of stable 10 nm to 500 nm supramolecular porphyrinic materials (2005)

Abstract Nanoscaled materials of organic dyes are of interest for a variety of potential applications because of the rich photonic properties that this class of molecules can impart. One mode to form such nanoscaled materials is via self‐organization and self‐assembly, using reasonably well understood methods in supramolecular chemistry. But there are inherent complexities that arise from the use of organic‐based supramolecular materials, including stability toward dioxygen, structural stability, and nanoarchitectures that may change with environmental conditions. Porphyrinoids have rich photonic properties yet are remarkably stable, have a rigid core, are readily functionalized, and metalation of the macrocycle can impart a plethora of optical, electronic, and magnetic properties. While there are many &lt;10 nm porphyrinic assemblies, which may or may not self‐organize into crystals, there is a paucity of 10–500 nm porphyrinic materials that can be isolated and stored. A variety of strategies towards the latter nanoscopic porphyrinic materials are discussed in terms of design, construction, and nanoarchitecture. The hierarchical structures include colloids, nanorods, nanotubes, nanorings, and nano‐crystalline materials. This prolegomenon emphasizes the supramolecular chemistry, structure‐stability, and structure‐function relationships. The goal herein is to examine general trends and delineate general principles.
FBG Incorporated Side-open Fabry-Perot Cavity for Simultaneous Gas Pressure and Temperature Measurements (2016)

A dual-parameter sensing structure based on a fiber Bragg grating (FBG) incorporated side-open Fabry-Perot cavity (FPC) is proposed and experimentally demonstrated for simultaneous measurements of gas pressure and temperature. The side-open FPC consisted of a micro-piece of chemical etched side-hole fiber acts as a pressure sensing unit. Two samples with different cavity lengths of 60 μm and 100 μm were fabricated and tested for gas pressure and temperature sensing in the experiment. Linear gas pressure responses of 4.063 pm/kPa and 4.071 pm/kPa in a large measuring range of 0-1000 kPa were obtained, respectively, which agree well with the theoretical analysis. Meanwhile, the temperature cross-sensitivities were measured as 214 Pa/° and 204 Pa/°. As a local temperature monitor, the incorporation of a short FBG in the leading single mode fiber was used to compensate the temperature cross-sensitivity of the sensor. This kind of compact and highly sensitive fiber sensor is appropriate for simultaneous gas pressure and temperature sensing in harsh micro environment.
The production of experimental vitamin A deficiency in rats and mice (1971)

Vitamin A deficiency in rats and mice was induced by restricting dams and litters from parturition to a pelleted diet made mainly from white flour. Young rats usually developed clear signs of avitaminosis A within 60 days from birth. Mice were more resistant, and some survived for periods up to 150 days from birth. Retention of traces of vitamin A in the liver was no more prolonged in mice than in rats. In mice, enlargement of the prostates and seminal vesicles, and atrophy of the testes, were usually the most prominent pathological features. In rats, timely treatment with vitamin A acid (retinoic acid) cured xerophthalmia and restored growth. Signs of deficiency reappeared soon after its administration was stopped. This procedure allows supplies of animals to be kept in good general health, but ready for the production of acute deficiency at short notice. Retinoic acid was also effective in curing deficient mice. Incidental observations on the eyes and reproductive powers of mice or rats dosed with retinoic acid, and on the response of rats to variations in the casein contents of their diet, are recorded.
Molecular analysis of tap2, an anther‐specific gene from Antirrhinum majus (1991)

Deficiens is a floral homeotic gene of Antirrhinum majus, mutation of which results in transformation of petals to sepals and stamens to carpels. In a search for putative target genes, controlled by this regulatory locus, cDNA clones representing genes, that are expressed in wild type but not in the deficiens mutant flowers, were isolated by differential screening. The molecular structure and the expression pattern of one of these genes, tap2, is described. Tap2 is transiently and tissue-specifically expressed in the tapetum of the anthers. It encodes a 131 amino-acids-long protein with a hydrophobic N-terminus, displaying all characteristic features of a signal peptide. This indicates that the TAP2 protein may be secreted.
8.2: Semiconductor Quantum Rods for Display Applications (2015)

Semiconductor Quantum rods offer new functionality for flat panel displays as they exhibit tunable narrow emission bands in addition to polarized emission and lower self‐absorption compared to other quantum materials. Qlight nanotech has developed a quantum rods based film for backlight units, enabling wide color gamut and the design of an energy‐efficient polarized backlight.
Analysis of closed-loop acoustic feedback cancellation systems (2013)

In a previous study, the performance of an acoustic feedback/echo cancellation system was analyzed using a power transfer function method. Whereas the analysis result provides very accurate performance predictions in open-loop acoustic echo cancellation systems, it is less accurate in closed-loop acoustic feedback cancellation systems if there is a strong correlation between the loudspeaker signal and the signals entering the microphones. This work extends the performance analysis to include the effects of the nonzero correlation on the adaptive filters. Simulation results verify that this extension provides much more accurate performance predictions in closed-loop acoustic feedback cancellation systems.
Shortening the Current Opioid Misuse Measure via computer-based testing: a retrospective proof-of-concept study (2013)

Curtailment and stochastic curtailment have the potential to achieve substantial reductions in respondent burden without compromising sensitivity and specificity. The two sequential methods should be considered for future computer-based administrations of the COMM.
The Use of Radium in the Treatment of Nevi (1929)

IN the consideration of this subject there are some interesting points to be brought out. I will mention briefly the types of nevi to be considered, other methods of treating nevi, and the experience of other workers, spending more time on the technic of treatment and end-results obtained after radium treatment. Nevi, as the name indicates, are usually present at birth. It has been estimated that 33 per cent of new born infants are so afflicted. Some nevi are fully formed at birth and do not seem to increase in size, except as they increase with the growth of the body; others are so small at birth as to he inconspicuous, but some time later show marked development. They may consist of areas of hyperplasia of the superficial capillaries or of the arteries or veins, or there may be an excessive deposit of pigment. Nevi are generally considered to be developmental defects, appearing sporadically without any hereditary tendency. Four common types of nevi are considered and they are named according to the type of tissue which predominates. (1) Nevus flammeus, or port wine mark, consisting of dilated capillaries; (2) nevus vasculosus, usually consisting of dilated arteries; (3) angioma cavernosum, consisting of inter-communicating blood spaces of abnormal size, usually of venous origin, and (4) nevus pigmentosus, consisting of abnormal tissue with an excessive amount of pigment. The last classification includes those with or without pilosis. These lesions are sometimes most disfiguring. The color may vary from a pale pink to a deep scarlet. They may be purple or blue, or, in the pigmented type, a very ugly brown. Some of the angiomata cavernosa show such an over-development of tissue as to be repulsive. Treatment is undertaken in order to remove or to shrink up as much of the abnormal tissue as possible, with a minimum of damage to surrounding areas, and to leave as healthy and inconspicuous a scar as possible. Wickham and Degrais are considered the pioneers in this work; at least, up until the time they published their book in 1907, nothing of any value had been published on this subject. Electrolysis had been almost the only method in use. This was painful, required repetition, and could not be used upon nevi of any considerable size. These authors reported a large number of birthmarks treated successfully. Since that time many methods have come into use, but radium still is the method of choice in a large percentage of such cases. In the consideration of other methods of treatment desiccation and electrocoagulation have a limited field. They are sometimes used in cases of nevus vasculosus, if the lesions are not too large, in preference to any other method. They are also used in the removal of the pigmented moles. McLean and Cannon mention the successful use of desiccation in the treatment of port wine marks. If one wishes to eradicate tissue which will not shrink up under radiation therapy, desiccation is probably the first choice.
