Determination Of In-Situ Permeability From Tube Wave Velocity And Attenuation (1986)

Recent investigations by a number of different authors have shown that the phase velocity and attenuation of the tube (Stoneley) wave in the borehole is correlated with in situ permeability. Specifically, velocity decreases and attenuation increases as a function of in situ permeability. Hsui et al. (1985) presented two theoretical models relating in situ permeability to tube wave attenuation. The results obtained from one of the models, the modified Biot-Rosenbaum model, agreed well with the data of Williams et al. (1984). We have extended the results from the modified Biot-Rosenbaum model to examine the relationship between tube wave velocity and in situ permeability. It is found that with an open borehole Biot-Rosenbaum model, i.e., allowing for the communication between the pore and borehole fluid pressures, we can match the variation of tube wave phase velocity with in situ permeability in the data presented by Williams et al. and by Zemanek et al. (1985). Furthermore, by the introduction of intrinsic attenuation, i.e., attenuation not caused by Biot fluid flow mechanism, we can fit both the velocity and attenuation data simultaneously. Williams et al. had also observed that the existence of a mudcake did not appear to significantly affect the observed correlation of tube wave velocity and attenuation with permeability. In the Biot-Rosenbaum model, this is explained by the fact that a mudcake is not rigid, and there can be communication between the pore and borehole fluid pressure systems without actual fluid exchange between them. Thus if one can determine the formation P- and S-wave velocity and attenuation, the in situ permeability may be obtainable using the Biot-Rosenbaum model.
Integrating Low-level and Semantic Features for Object Consistent Segmentation (2015)

The aim of semantic segmentation is to assign each pixel a semantic label. Numerous methods for semantic segmen-tation have been proposed in recent years and most of them chose pixel or superpixel as the processing primitives. However, as the information contained in a pixel or a superpixel is not discriminative enough, the outputs of these algorithms are usually not object consistent. To tackle this problem, we introduce the concept of object-like regions as a new and higher level processing primitive. We first experimentally showed that using groundtruth segments as pro-cessing primitives can boost semantic segmentation accuracy, and then proposed a novel method to produce regions that resemble the groundtruth regions, which we named them as ‘object-like regions’. We achieve this by integrating state of the art low-level segmentation algorithms with typical semantic segmentation algorithms through a novel se-mantic feature feedback mechanism. We present experimental results on the publicly available image understanding dataset MSRC21 and stanford background dataset, showing that the new method can achieve relatively good semantic segmentation results with far fewer processing primitives.
<p>Comparison of Skin Permeation and Putative Anti-Inflammatory Activity of Commercially Available Topical Products Containing Ibuprofen and Diclofenac</p> (2020)

Diclofenac exhibited superior anti-inflammatory activity as measured by the index. Differences beyond drug concentration, including excipients, drug salt form, and dosage form, contribute to differences in absorption and thus in anti-inflammatory activity. Both absorption and COX-2 inhibition potency are important for anti-inflammatory activity, but their priority depends upon the products being compared-with the same NSAID, absorption determines superiority; with different NSAIDs, superiority is determined by the balance between absorption and COX-2 potency. These findings should be considered when selecting a topical NSAID for treating patient pain and inflammation.
DETERMINATION OF SERUM VISININ LIKE PROTEIN-1 AND ITS POTENTIAL FOR THE DIAGNOSIS OF BRAIN INJURY DUE TO THE STROKE - A PILOT STUDY (2011)

We have introduced a new analytical tool for the study of VILIP-1. Our results support the hypothesis that serum VILIP-1 may be associated with ischemic stroke. The ELISA VILIP-1 assay offers a new research tool for the diagnosis and pathophysiology of stroke and other CNS diseases.
Unified approach to describe optical pulse generation by propagation of periodically phase-modulated CW laser light (2006)

The analysis of optical pulse generation by phase modulation of narrowband continuous-wave light, and subsequent propagation through a group-delay-dispersion circuit, is usually performed in terms of the so-called bunching parameter. This heuristic approach does not provide theoretical support for the electrooptic flat-top-pulse generation reported recently. Here, we perform a waveform synthesis in terms of the Fresnel images of the periodically phase-modulated input light. In particular, we demonstrate flat-top-pulse generation with a duty ratio of 50% at a quarter of the Talbot condition for the sinusoidal phase modulation. Finally, we propose a binary modulation format to generate a well-defined square-wave-type optical bit pattern.
Intensified Multispectral Imaging System for Poultry Carcass Inspection (1994)

A multispectral imaging system possessing six optical filters at 542, 570, 641, 700, 720, and 847 nm was demonstrated feasible for discriminating normal poultry carcasses from abnormal carcasses. Gray level image intensities of selected wavelengths were used to classify normal carcasses from abnormal carcasses. Visible wavelengths, 542, 570, and 641 nm, were useful for separation of normal carcasses from septicemic and cadaver carcasses. The accuracy was 89.3% for separation of normal carcasses from abnormal carcasses. The accuracy for separation of the normal carcasses from the septicemic was 89.3%, and from cadaver, 96.5%. Among the abnormal carcasses, the accuracy of classification of the septicemic carcasses was 90.0% and of the cadaver carcasses, 96.6%. The accuracies of classification for poultry carcasses into three classes using a neural networks classifier were 92.9% for normal, 83.4% for septicemic, and 96.6% for cadaver carcasses.
Effects of histidine and imidazolelactic acid on various parameters of the oxidative stress in cerebral cortex of young rats (2004)

Histidinemia is an inherited metabolic disorder caused by deficiency of histidase activity, which leads to tissue accumulation of histidine and its derivatives. Affected patients usually present with speech delay and mental retardation, although asymptomatic patients have been reported. Considering that the pathophysiology of the neurological dysfunction of histidinemia is not yet understood and since histidine has been considered a pro-oxidant agent, in the present study we investigated the effect of histidine and one of its derivatives, l-beta-imidazolelactic acid, at concentrations ranging from 0.1 to 10 mM, on various parameters of oxidative stress in cerebral cortex of 30-day-old Wistar rats. Chemiluminescence, total radical-trapping antioxidant potential (TRAP), thiobarbituric acid reactive substances (TBA-RS), and the activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) were measured in tissue homogenates in the presence of l-histidine or l-beta-imidazolelactic acid. We observed that l-histidine provoked an increase of chemiluminescence and a reduction of TRAP at concentrations of 2.5 mM and higher, while TBA-RS measurement, GSH-Px, CAT and SOD activities were not affected. Furthermore, l-beta-imidazolelactic acid provoked antioxidant effects at high concentrations (5-10 mM) as observed by the reduction of chemiluminescence, although this compound enhanced chemiluminescence at low concentrations (0.5-1 mM). These results suggest that in vitro oxidative stress is elicited by histidine but only at supraphysiological concentrations.
High triplet energy exciplex hosts for deep blue phosphorescent organic light-emitting diodes (2017)

High triplet energy exciplex hosts for deep blue phosphorescent organic light-emitting diodes were developed by synthesizing a high triplet energy hole transport type host material designed for exciplex formation with a high triplet energy electron transport type host material derived from a diphenyltriazine.
Initial phase formation and dissociation in the thin-film Ni/Al system (1985)

We have investigated the interactions of Al/Ni, Al/NiAl/Ni, Al/Ni3Al, and NiAl3/Ni thin films between 300 and 425 °C. The films were prepared by sequential evaporation and coevaporation, then vacuum annealed and analyzed by Rutherford backscattering and x-ray diffraction. The reaction always started at the interface in contact with the most Al-rich film and resulted in formation and growth of NiAl3, unless that was the most Al-rich layer. Subsequently the reaction proceeded to Ni2Al3. We conclude that the kinetics rather than the thermodynamics is responsible for determining the growth of these phases.
Finding Software Vulnerabilities by Smart Fuzzing (2011)

Nowadays, one of the most effective ways to identify software vulnerabilities by testing is the use of fuzzing, whereby the robustness of software is tested against invalid inputs that play on implementation limits or data boundaries. A high number of random combinations of such inputs are sent to the system through its interfaces. Although fuzzing is a fast technique which detects real errors, its efficiency should be improved. Indeed, the main drawbacks of fuzz testing are its poor coverage which involves missing many errors, and the quality of tests. Enhancing fuzzing with advanced approaches such as: data tainting and coverage analysis would improve its efficiency and make it smarter. This paper will present an idea on how these techniques when combined give better error detection by iteratively guiding executions and generating the most pertinent test cases able to trigger potential vulnerabilities and maximize the coverage of testing.
PHYTOESTROGENS (2004)

Collectively, plants contain several different families of natural products among which are compounds with weak estrogenic or antiestrogenic activity toward mammals. These compounds, termed phytoestrogens, include certain isoflavonoids, flavonoids, stilbenes, and lignans. The best-studied dietary phytoestrogens are the soy isoflavones and the flaxseed lignans. Their perceived health beneficial properties extend beyond hormone-dependent breast and prostate cancers and osteoporosis to include cognitive function, cardiovascular disease, immunity and inflammation, and reproduction and fertility. In the future, metabolic engineering of plants could generate novel and exquisitely controlled dietary sources with which to better assess the potential health beneficial effects of phytoestrogens.
Novel intergenic repeats of K-12 (1999)

An online catalog of intergenic DNA repeat sequence elements is added to the EcoGene Escherichia coli K-12 genome sequence annotation and analysis project (bmb.med.miami.edu/EcoGene). A library of noncoding (intergenic) DNA sequences depleted of known intergenic repeat classes was searched for DNA sequence similarities to identify novel DNA repeat sequence classes.
A method for attribute selection in inductive learning systems (1988)

A computable measure was developed that can be used to discriminate between attributes on the basis of their potential value in the formation of decision rules by the inductive learning process. This relevance measure is the product of extensions to an information-theoretic foundation that address the particular characteristics of a class of inductive learning algorithms. The measure is also conceptually compatible with approaches from pattern recognition. It is described in the context of a generalized model of the expertise development process, and an experiment is presented in which a significant reduction in the number of attributes to be considered was achieved for a complex medical domain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Role for Histone Acetylation in the Developmental Regulation of V(D)J Recombination (2000)

VDJ recombination is developmentally regulated in vivo by enhancer-dependent changes in the accessibility of chromosomal recombination signal sequences to the recombinase, but the molecular nature of these changes is unknown. Here histone H3 acetylation was measured along versions of a transgenic VDJ recombination reporter and the endogenous T cell receptor alpha/delta locus. Enhancer activity was shown to impart long-range, developmentally regulated changes in H3 acetylation, and H3 acetylation status was tightly linked to VDJ recombination. H3 hyperacetylation is proposed as a molecular mechanism coupling enhancer activity to accessibility for VDJ recombination.
Management of a Patient with a Diagnosis of Bilateral Plantar Fasciitis and Achilles Tendinitis (1988)

This case report describes an approach for determining when fabricated orthoses might be useful in the treatment of a patient with foot-related problems. The patient is of special interest because she is an aerobics instructor, and her type of injury is relatively common. Particular emphasis in the report is placed on hypothesizing the cause of the patient's complaints and then basing treatment on that hypothesis.
Electrodeposition of PbO and its in situ conversion to CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> for mesoscopic perovskite solar cells (2014)

The perovskite CH3NH3PbI3 was prepared on a mesoscopic TiO2 film, starting from electrodepositing PbO, to iodination to PbI2, and then interdiffusion reaction with CH3NH3I. The as-prepared film was used as a light absorber for the perovskite solar cells, exhibiting a high PCE of 12.5% under standard AM 1.5 conditions.

The Pineal and Its Hormones in the Control of Reproduction in Mammals* (1980)

ONLY A LITTLE over a decade ago, any discussion of the function of the pineal gland included qualifying adjectives such as alleged, supposed, and putative. In the same vein, since it connoted a hormonal function, rather than referring to the pineal as a gland, the phrase pineal organ was usually employed to describe this portion of the epithalamus. However, this is no longer the case, at least in mammals. By the usual criteria in endocrinology, the pineal now fulfills all the qualifications of an organ of internal secretion. Several major discoveries revolutionized ideas concerning the function of the pineal gland. Certainly, as noted frequently in other reviews, the isolation and identification of N-acetyl-5-methoxytryptamine (melatonin), a pineal hormone, from bovine pineal tissue by Lerner et al. (1, 2) provided a strong impetus for subsequent investigations on this sometimes exasperating organ. At least as important as this discovery, however, were the observations that light and darkness govern both the biosynthetic activity (3, 4) and endocrine capability (5, 6) of the gland. These findings provided the scientific community with a heretofore unknown handle that could be used to exploit and elucidate the functions of the pineal. Indeed, it is my conviction that the one major factor that stymied pineal research until the mid-1960s was the lack of the basic knowledge that the endocrine output of the pineal gland is determined by the photoperiod to which the experimental subjects, be they animals or man, are exposed.
Self-Assembly of Microchips on Substrates (2006)

We demonstrated a technique for self-assembly using a plurality of silicon microchips onto a silicon substrate and performing further self-alignment at a high temperature to form permanently electrical connection by the eutectic solder bumps. Self-assembly is presented by controlling the hydrophobic-hydrophilic surface property of patterned microchips and substrate, and then self-alignment is accomplished using solder-based surface tension for flip chip assembly. The substrate is patterned and printed with flux and solder paste on the binding sites during assembly process, while the uncoated areas are transferred into hydrophilicity by using ion plasma cleaning. On the microchips, self-assembled monolayers (SAMs) are developed onto the patterned gold surface of the chips using 0.1M alkanethiol precursor molecules. On the other hand, the substrate is dipped with hydrophobic 2-ethyl-1-hexanol liquids on the binding sites. As soon as the hydrophobic pattern on a chip comes into contact with a substrate-binding site, the patterned gold surfaces are selectively wet and adhered to the hydrophobic adhesives of the substrate. These components are self-assembled in water by minimization of the surface energy that provides the driving force for the assembly. Next, at a temperature above its melting point of 183/spl deg/C, the solder melts; self aligns, and connects electronically between self-assembled microchips and the substrate. This self-alignment process is compatible with the surface mount technique (SMT). Also, use of different bonding sizes and shapes help enhancing the self-assembly performance.
Empirical Analysis of Factors Impacting Turnover Intention among Manufacturing Workers (2019)

The purpose of this study was to investigate how turnover intention relates to job satisfaction, organizational commitment, leadership, job performance, and work-family conflict among manufacturing workers in Tennessee, USA. A causal model was proposed, and a turnover intention survey questionnaire for manufacturing workers was developed. The data were collected from manufacturing companies in the Tennessee area and analyzed by SPSS and structural equation modeling (SEM). The results of our study indicated that job satisfaction and organizational commitment negatively and significantly affected manufacturing workers&rsquo; turnover intentions, while work-family conflict positively and significantly affected turnover intentions. Although leadership indirectly influenced turnover intention, its effects on turnover intention were fully mediated by job satisfaction and organizational commitment. No effect of job performance on turnover intention was found in this study with manufacturing workers. The results suggested that policies for enhancing worker job satisfaction and organizational commitment, balancing work-family conflict, and improving leadership style should be proposed to reduce turnover intention.
A Permutation Disalignment Index-Based Complex Network Approach to Evaluate Longitudinal Changes in Brain-Electrical Connectivity (2017)

In the study of neurological disorders, Electroencephalographic (EEG) signal processing can provide valuable information because abnormalities in the interaction between neuron circuits may reflect on macroscopic abnormalities in the electrical potentials that can be detected on the scalp. A Mild Cognitive Impairment (MCI) condition, when caused by a disorder degenerating into dementia, affects the brain connectivity. Motivated by the promising results achieved through the recently developed descriptor of coupling strength between EEG signals, the Permutation Disalignment Index (PDI), the present paper introduces a novel PDI-based complex network model to evaluate the longitudinal variations in brain-electrical connectivity. A group of 33 amnestic MCI subjects was enrolled and followed-up with over four months. The results were compared to MoCA (Montreal Cognitive Assessment) tests, which scores the cognitive abilities of the patient. A significant negative correlation could be observed between MoCA variation and the characteristic path length ( λ ) variation ( r = - 0 . 56 , p = 0 . 0006 ), whereas a significant positive correlation could be observed between MoCA variation and the variation of clustering coefficient (CC, r = 0 . 58 , p = 0 . 0004 ), global efficiency (GE, r = 0 . 57 , p = 0 . 0005 ) and small worldness (SW, r = 0 . 57 , p = 0 . 0005 ). Cognitive decline thus seems to reflect an underlying cortical “disconnection” phenomenon: worsened subjects indeed showed an increased λ and decreased CC, GE and SW. The PDI-based connectivity model, proposed in the present work, could be a novel tool for the objective quantification of longitudinal brain-electrical connectivity changes in MCI subjects.
Rapid document navigation for information triage support (2007)

This paper introduces a novel interaction for supporting rapid between-page comparison of texts within a limited screen estate. In comparison with existing interfaces and interactions, it gives a high degree of visual feedback and allows rapid between-page flicking, similar to what is readily achieved in physical environments using the fingers and thumbs of a reader as they flip between related pages.
SALSA, a variant of yeast SAGA, contains truncated Spt7, which correlates with activated transcription (2002)

Spt-Ada-Gcn5 acetyltransferase (SAGA) is a previously described histone acetyltransferase/transcriptional coactivator complex in yeast. At promoters of certain genes (HIS3 and TRP3), SAGA has an inhibitory function involving a nonproductive TATA-binding protein interaction mediated by the Spt3 and Spt8 subunits. Related to this, Spt8-less SAGA is a major form of the complex under activating conditions for these genes. In the present study, we purify this activation-specific complex, called SALSA (SAGA altered, Spt8 absent). Besides lacking Spt8, SALSA contains Spt7 subunit that is truncated. Examining the role of this subunit, we find that C-terminally truncated SPT7 resulted in derepressed HIS3 transcription. Furthermore, when grown in rich media (repressing conditions), wild-type cells yielded predominantly SAGA, but Spt7 C-terminal truncations resulted primarily in a form of complex similar to SALSA. Thus, SALSA-like structure and activating function can be partially recapitulated in yeast by truncating the C terminus of Spt7. Overall, these results lead to a model that for a subset of promoters SAGA is inhibitory through Spt3, Spt8, and an Spt8-interacting subdomain of Spt7, whereas SALSA is a form of complex for positive transcriptional regulation. These data clarify a mechanism by which a transcriptional regulatory complex can switch between positive and negative modulation.
Biochemical detection and monitoring of alcohol abuse and abstinence (2001)

The merits and limitations of traditional and new markers for alcohol abuse (and abstinence) are critically examined for detection and monitoring of alcoholics, hazardous drinkers and binge drinkers. The traditional markers discussed include γ-glutamyltransferase (GGT), aspartate and alanine aminotransaminases (AST, ALT) and mean corpuscular volume (MCV); new markers include mitochondrial AST, carbohydrate-deficient transferrin (CDT), serum/urine 5- hydroxytryptophol, β-hexosaminidase and acetaldehyde adducts. The strengths and weaknesses of several of the self-reporting screening questionnaires are also explored. No laboratory test is reliable enough on its own to support a diagnosis of alcoholism. Sensitivities and specificities vary considerably and depend on the population concerned. GGT continues to remain the test that combines greatest convenience and sensitivity; its diagnostic accuracy can be enhanced by combination with other traditional markers (AST, ALT, MCV). None of the newer markers offers significant advantage, although CDT seems to be better at monitoring patients for increased alcohol consumption or progress towards abstinence.
