Application of reciprocal time generation technique to digital temperature measurement (1994)

A thermistor-based temperature indicator is described, which produces a parallel digital output proportional to absolute temperature, using the principle of a reciprocal time generator. The instrument is suitable for fast measurement of temperature, with easy facility of range adjustment. Temperature indication in degrees Celsius is also possible, using additional simple circuitry. Experimental results are given in support of the proposed method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-bandwidth acoustic detection system (HBADS) for stripmap synthetic aperture acoustic imaging of canonical ground targets using airborne sound and a 16 element receiving array (2018)

High Bandwidth Acoustic Detection System (HBADS) is an emerging active acoustic sensor technology undergoing study by the US Army’s Night Vision and Electronic Sensors Directorate. Mounted on a commercial all-terrain type vehicle, it uses a single source pulse chirp while moving and a new array (two rows each containing eight microphones) mounted horizontally and oriented in a side scan mode. Experiments are performed with this synthetic aperture air acoustic (SAA) array to image canonical ground targets in clutter or foliage. A commercial audio speaker transmits a linear FM chirp having an effective frequency range of 2 kHz to 15 kHz. The system includes an inertial navigation system using two differential GPS antennas, an inertial measurement unit and a wheel coder. A web camera is mounted midway between the two horizontal microphone arrays and a meteorological unit acquires ambient, temperature, pressure and humidity information. A data acquisition system is central to the system’s operation, which is controlled by a laptop computer. Recent experiments include imaging canonical targets located on the ground in a grassy field and similar targets camouflaged by natural vegetation along the side of a road. A recent modification involves implementing SAA stripmap mode interferometry for computing the reflectance of targets placed along the ground. Typical strip map SAA parameters are chirp pulse = 10 or 40 ms, slant range resolution c/(2*BW) = 0.013 m, microphone diameter D = 0.022 m, azimuthal resolution (D/2) = 0.01, air sound speed c ≈ 340 m/s and maximum vehicle speed ≈ 2 m/s.
NonStop SQL/MX primitives for knowledge discovery (1999)

In this paper, we describe the primitives that we have implemented in NonStop SQL/MX, a commercial DBMS, to support the knowledge discovery process. These primitives, combined with the high-performance SQL&IX engine, represent a powerful kernel for performing basic knowledge discovery tasks in a scalable and efftcient manner.
Glycyl-glutamine inhibits the respiratory depression, but not the antinociception, produced by morphine (2000)

Glycyl-glutamine (Gly-Gln; beta-endorphin(30-31)) is an endogenous dipeptide that is synthesized through the posttranslational processing of beta-endorphin in brain stem regions that control respiration and autonomic function. This study tested the hypothesis that Gly-Gln administration to conscious rats will prevent the respiratory depression caused by morphine without affecting morphine antinociception. Rats were administered Gly-Gln (1-100 nmol) or saline (10 microl) intracerebroventricularly followed, 5 min later, by morphine (40 nmol icv). Arterial blood gases and pH were measured immediately before Gly-Gln and 30 min after morphine injection. Gly-Gln pretreatment inhibited morphine-induced hypercapnia, hypoxia, and acidosis significantly. The response was dose dependent and significant at Gly-Gln doses as low as 1 nmol. In contrast, Gly-Gln (1-300 nmol) had no effect on morphine-evoked antinociception in the paw withdrawal test. When given alone to otherwise untreated animals, Gly-Gln did not affect nociceptive latencies or blood gas values. These data indicate that Gly-Gln inhibits morphine-induced respiratory depression without compromising morphine antinociception.
Style2Vec: Representation Learning for Fashion Items from Style Sets (2017)

With the rapid growth of online fashion market, demand for effective fashion recommendation systems has never been greater. In fashion recommendation, the ability to find items that goes well with a few other items based on style is more important than picking a single item based on the user's entire purchase history. Since the same user may have purchased dress suits in one month and casual denims in another, it is impossible to learn the latent style features of those items using only the user ratings. If we were able to represent the style features of fashion items in a reasonable way, we will be able to recommend new items that conform to some small subset of pre-purchased items that make up a coherent style set. We propose Style2Vec, a vector representation model for fashion items. Based on the intuition of distributional semantics used in word embeddings, Style2Vec learns the representation of a fashion item using other items in matching outfits as context. Two different convolutional neural networks are trained to maximize the probability of item co-occurrences. For evaluation, a fashion analogy test is conducted to show that the resulting representation connotes diverse fashion related semantics like shapes, colors, patterns and even latent styles. We also perform style classification using Style2Vec features and show that our method outperforms other baselines.
cDNA cloning, nucleotide sequence and expression of the gene for arylsulfatase in the sea urchin (<i>Hemicentrotus pulcherrimus</i>) embryo (1988)

Arylsulfatase is known to be synthesized in large amounts at the early gastrula stage of sea urchin development. We determined the amino acid sequence of a portion of the purified sea urchin embryonic arylsulfatase, and then isolated a cDNA clone for arylsulfatase by screening a sea urchin plutei lambda gt10 cDNA library with an oligodeoxynucleotide probe synthesized according to the determined amino acid sequence. The longest cDNA clones were selected and the nucleotide sequence determined. The cDNA is 2422 nucleotides long and encodes 551 amino acids. The deduced amino acid sequence has not sequence similarity with any of the peptides registered in NBRF peptide databank. Northern blot analysis revealed that the arylsulfatase cDNA hybridizes to a 2.9-kb mRNA. This mRNA exists in the unfertilized egg in small amounts, but markedly increases after the blastula stage preceding the increase of the arylsulfatase activity.
Synthesis of difurazanyl ethers from 4,4′-dinitroazoxyfurazan (2000)

Nonselective attacks at the carbon bonded to a nitro group and carbon bonded to the N(O) atom of the azoxy group were observed in the reactions of 4,4′-dinitroazoxyfurazan with bases and nucleophiles. A mechanism is presented to account for both of the pathways to products. A series of new difurazanyl ether derivatives was synthesized. © 2000 John Wiley & Sons, Inc. Heteroatom Chem 11:48–56, 2000

A low power and high speed CMOS Voltage-Controlled Ring Oscillator (2004)

In this paper a new Voltage Controlled Ring Oscillator is presented. The proposed VCO uses partial positive feedback in its delay cell, allowing the circuit to operate with single two stages, achieving high speed with reduced power consumption. The new VCO has a wide range of operation frequencies (0.2 at 2.1 GHz), good linearity between the output frequency and the control voltage, phase noise of -90 dBc/Hz at 100 kHz offset and it only consumes 7.01 mW in its central frequency of 1.2 GHz using a 3.3 V power supply. The circuit was fabricated in a 0.35 /spl mu/m CMOS-AMS process and occupies an area of 67.5/spl times/77.5 /spl mu/m/sup 2/.
Medicinal Chemistry (2016)

The objective of the glossary is to provide in a single document a consistent terminology and concise definitions of terms covering the various aspects of medicinal chemistry. This was felt necessary with regard to the rapid changes occuring in medicinal chemistry and also by the need to establish international definition standards. Effectively the possibility exists that in different countries certain terms may not have the same meaning, in such a case the creation of an internationally accepted definition is particularly justified.
Cyclosporin A Traps ABCA1 at the Plasma Membrane and Inhibits ABCA1-Mediated Lipid Efflux to Apolipoprotein A-I (2004)

ABCA1 inhibition by cyclosporin A supports a role for ABCA1 endocytic trafficking in ABCA1-mediated lipid efflux and could explain in part the low HDL levels observed in some patients with transplants.

Learning the Localization Function: Machine Learning Approach to Fingerprinting Localization (2018)

Considered as a data-driven approach, Fingerprinting Localization Solutions (FPSs) enjoy huge popularity due to their good performance and minimal environment information requirement. This papers addresses applications of artificial intelligence to solve two problems in Received Signal Strength Indicator (RSSI) based FPS, first the cumbersome training database construction and second the extrapolation of fingerprinting algorithm for similar buildings with slight environmental changes. After a concise overview of deep learning design techniques, two main techniques widely used in deep learning are exploited for the above mentioned issues namely data augmentation and transfer learning. We train a multi-layer neural network that learns the mapping from the observations to the locations. A data augmentation method is proposed to increase the training database size based on the structure of RSSI measurements and hence reducing effectively the amount of training data. Then it is shown experimentally how a model trained for a particular building can be transferred to a similar one by fine tuning with significantly smaller training numbers. The paper implicitly discusses the new guidelines to consider about deep learning designs when they are employed in a new application context.
DNA Amplification Fingerprinting and Hybridization Analysis of Centipedegrass (1995)

DNA amplification fingerprinting (DAF) with arbitrary oligonucleotide primers provides germplasm analyses for cultivar identification and protection of proprietary rights, and constitutes an effective tool in marker‐assisted breeding and in the study of genetic variation within natural and domesticated populations. In this study, DAF was used to infer genetic relationships in centipedegrass [ Eremochloa ophiuroides (Munro) Hack.]. An optimization of reaction components defined amplification conditions that reproducibly fingerprinted centipedegrass and other turfgrass species. Cultivars Tennessee Hardy, Tennessee Tuff, Oklawn, Centennial, and Tifton common were analyzed with 14 octamer primers. Four primers produced polymorphic patterns, two of which differentiated all cultivars. Phylogenetic analysis using parisomy (PAUP) distinctly separated cold‐tolerant Tennessee Hardy. Numerous monomorphic bands were obtained, suggesting that the centipedegrass cultivars are closely related and are from a common origin. Several DAF bands were isolated from silver‐stained polyacrylamide gels for use as hybridization probes. A monomorphic 200‐base pair (bp) band that hybridized to a single amplification product detected eight homologous regions in genomic centipedegrass DNA. When hybridized to DAF patterns obtained from other turfgrass species, such as bermudagrass [ Cynodon dactylon (L) Pers. × Cynodon transvaalensis Burtt‐Davyl, rough bluegrass ( Poa trivialis L.) and Zoysia ( Zoysia japonica Steud.), the 200‐bp fragment, and a 175‐bp fragment generated with a different primer, resulted in smearing patterns. While these products are only present within one size amplicon in centipedegrass fingerprints, the smearing indicated that the putative sequence was present in multiple copies throughout the amplification profile, was abundant in the heterologous grass genomes, and may have represented a family of repetitive DNA sequences. Our results indicated that DAF can generate molecular markers that can be used reliably for DNA fingerprinting of important centipedegrass cultivars. This tool would be useful in determining genetic relationships and diversity, and in establishing possible origins of cultivars.
DNA interstrand crosslink repair in mammalian cells: step by step (2009)

Interstrand DNA crosslinks (ICLs) are formed by natural products of metabolism and by chemotherapeutic reagents. Work in E. coli identified a two cycle repair scheme involving incisions on one strand on either side of the ICL (unhooking) producing a gapped intermediate with the incised oligonucleotide attached to the intact strand. The gap is filled by recombinational repair or lesion bypass synthesis. The remaining monoadduct is then removed by nucleotide excision repair (NER). Despite considerable effort, our understanding of each step in mammalian cells is still quite limited. In part this reflects the variety of crosslinking compounds, each with distinct structural features, used by different investigators. Also, multiple repair pathways are involved, variably operative during the cell cycle. G(1) phase repair requires functions from NER, although the mechanism of recognition has not been determined. Repair can be initiated by encounters with the transcriptional apparatus, or a replication fork. In the case of the latter, the reconstruction of a replication fork, stalled or broken by collision with an ICL, adds to the complexity of the repair process. The enzymology of unhooking, the identity of the lesion bypass polymerases required to fill the first repair gap, and the functions involved in the second repair cycle are all subjects of active inquiry. Here we will review current understanding of each step in ICL repair in mammalian cells.

High Power-Supply-Rejection (PSR) Current-Mode Low-Dropout (LDO) Regulator (2010)

Modern system-on-a-chip (SoC) solutions suffer from limited on-chip capacitance, which means that the switching events of functionally dense ICs induce considerable noise in the supplies. This ripple worsens the accuracy of sensitive analog electronics, such as ADCs, PLLs, and VCOs, etc. Without dropping a substantial voltage, point-of-load (PoL) low-dropout (LDO) regulators reduce (filter) this noise but only as much as their loop gains and bandwidths allow. This brief presents a 5-mA 1.5-μm bipolar current-mode LDO regulator that, with a higher bandwidth current loop, suppresses higher frequency noise by 49 dB (i.e., power-supply rejection) up to 10 MHz with only 68 nF at the output, which is 20 dB better than its voltage-mode counterpart.
Metabolic reprogramming in glioblastoma: the influence of cancer metabolism on epigenetics and unanswered questions (2015)

A defining hallmark of glioblastoma is altered tumor metabolism. The metabolic shift towards aerobic glycolysis with reprogramming of mitochondrial oxidative phosphorylation, regardless of oxygen availability, is a phenomenon known as the Warburg effect. In addition to the Warburg effect, glioblastoma tumor cells also utilize the tricarboxylic acid cycle/oxidative phosphorylation in a different capacity than normal tissue. Altered metabolic enzymes and their metabolites are oncogenic and not simply a product of tumor proliferation. Here we highlight the advantages of why tumor cells, including glioblastoma cells, require metabolic reprogramming and how tumor metabolism can converge on tumor epigenetics and unanswered questions in the field.
Electronic Surveying: Electronic Distance Measurements (1963)

Electronic instruments for the precise determination of short distances are well known, but the electronic basis for their operation has never been clearly outlined in a single publication. Details regarding the electronic circuits used in these instruments are reviewed and compared to indicate the similarities and the differences in the various methods of determining distance from a measurement of time. The relation between the travel time and the phase of a periodic signal is indicated. Methods for eliminating electronic zero errors and the use of signals with different frequencies to eliminate ambiguity in the measured distances are described. The effect of atmospheric refraction on the velocity of propagation and different methods for including corrections for atmospheric conditions are reviewed. Relative advantages of microwave and optical systems are compared and recommendations are suggested for an ideal instrument combining the best features of both types.
Optimal local register allocation for a multiple-issue machine (1994)

This paper presents an algorithm that allocates registers optimally for straight-line code running on a generic multi-issue computer. On such a machine, an optimal register allocation is one that minimizes the number of issue slots that the code requires. Optimal spill selection and load/store placement are used to minimize the number of additional issue slots needed, given a schedule for the non-memory reference instructions and a fixed number of available physical registers. The generic multi-issue machine model closely models the operation of vector and VLIW processors, and could be extended to model super-scalar processors. The algorithm uses dynamic programming to search the state space of feasible register allocations; implicit and explicit state pruning are used to make the problem tractable without sacrificing optimality. The optimal allocation produced by the algorithm for a substantial example is presented.
Location-Based IP Addressing in IP-Enable Wireless Sensor Networks (2011)

Network addressing is a traditional problem in communications network. IP addressing which can fully reflect the characteristics of Wireless Sensor Network will provide good support for the design of network routing and management protocols. The location information which is important in most of WSN application can be used to simplify routing policy, and is also supported by IPv6. In this paper, we propose a location-based IP addressing protocol. We assume that nodes in Wireless Sensor Network know their current physical location; thus, this location information can be exploited to facilitate the generation of Location-based IP address. This paper describes Location-based IP addressing architecture for WSNs multicast and unicast within a local or metropolitan environment using two-dimensional address structures and analyzes the implementation in 6LoWPAN.
Missense mutation (R15W) of the connexin32 gene in a family with X chromosomal Charcot-Marie-Tooth neuropathy with only female family members affected (1997)

A small family with sensorimotor neuropathy of dominant inheritance was examined. All three affected members were female. They had unusually severe symptoms and pronounced reduction of motor nerve conduction velocities with absent sensory nerve action potentials. Molecular genetic analysis disclosed a missense mutation in the connexin32 gene in codon 15 (Arg15Trp) which predicts the replacement of a basic amino acid to a non-polar amino acid in the first cytoplasmic loop of the protein. This report illustrates that in small pedigrees in which only women are affected, and which show a severe clinical phenotype, X chromosomal Charcot-Marie-Tooth neuropathy should be considered as differential diagnosis.
[Susceptibility of Clostridium difficile strains to teicoplanin and ramoplanin]. (1993)

The in vitro activity of teicoplanin and ramoplanin against 113 Clostridium difficile strains isolated from different origins was determined. The minimum inhibitory concentrations (MICs) of antibiotics were determined by the agar dilution method. MIC of teicoplanin and ramoplanin were twofold lower for Clostridium difficile strains isolated from patient with pseudomembranous colitis. No correlation between the origin of the strains toxigenicity and susceptibility to teicoplanin and ramoplanin was observed. Our result indicate that teicoplanin and ramoplanin are potentially effective alternative antibiotics for treatment of infections caused by Clostridium difficile.
