AUDIT‐C and ICD codes as phenotypes for harmful alcohol use: association with ADH1B polymorphisms in two US populations (2018)

The age-adjusted mean AUDIT-C score is associated more strongly with genetic polymorphisms of known risk for alcohol use disorder than are longitudinal trajectories of AUDIT-C or AUD diagnostic codes. AUD diagnostic codes modestly enhance this association.
Spontaneous flow reversals in Rayleigh-Bénard convection of a liquid metal (2011)

We report a finding of spontaneous flow reversals of roll-like patterns in liquid gallium Rayleigh-Bénard convection. The vessel has a square geometry with an aspect ratio of 5, and a horizontal magnetic field is applied to align the rolls. The flow patterns were visualized by ultrasonic velocity measurements, and the processes of the reversal were clearly observed. The basic flow pattern observed in the vessel is a four-roll structure with its axis parallel to the magnetic field. Emergence of a new circulation at a corner of the vessel causes flow reversal with reorganization of the whole pattern. The flow keeps relatively steady four-roll structure for most of the duration, while the reversal of it is over in a short time. The reversals of the flow occur randomly with the interval time between reversals being much longer than the circulation time.
A Pauson−Khand-Type Reaction between Alkynes and Olefinic Aldehydes Catalyzed by Rhodium/Cobalt Heterobimetallic Nanoparticles:  An Olefinic Aldehyde as an Olefin and CO Source (2004)

Co/Rh (Co:Rh = 2:2) heterobimetallic nanoparticles derived from Co(2)Rh(2)(CO)(12) react with alkynes and alpha,beta-unsaturated aldehydes such as acrolein, crotonaldehyde, and cinnamic aldehyde and release products resulting from [2 + 2 + 1]cycloaddition of alkyne, carbon monoxide, and alkene. alpha,beta-Unsaturated aldehydes act as a CO and alkene source. These reactions produce 2-substituted cyclopentenones.
Preorganized tridentate analogues of mixed hydroxyoxime/carboxylate nickel extractants (2016)

A series of 22 tridentate unsaturated mono-anionic ligands having the atom-sequence Y-C[double bond, length as m-dash]C-N=CH-C=C-Z(-1), with Y = N, O, or S and Z = O or S, has been studied to establish whether this backbone could be used to develop strong solvent extractants for nickel(II) which will preferably also show a high selectivity over iron(III) in the pH-dependent process: 2LH(org) + NiSO4 ⇌ [(L)2Ni]org + H2SO4. All are capable of forming octahedral [(L)2Ni] complexes with a mer-arrangement of the YNZ(-1) donor set. X-ray crystal structures of three salicylaldimine proligands derived from 3-bromo-5-t-butyl-2-hydroxybenzaldehyde show these to have pre-organised donor sets in which the three donors are held in an approximately orthogonal arrangement by intramolecular hydrogen bonds. The tautomers observed are dependent on the nature of the Y atom and the extent to which it is favourable for this to form a bonding interaction with the acidic hydrogen atom on the salicylaldimine unit. X-ray crystal structure determinations of seven of the [(L)2Ni] complexes show these to have significantly distorted octahedral coordination geometries which partly account for the proligands proving to be fairly weak Ni-extractants. DFT calculations show that extractant strength is dependent on a combination of the binding strength of the YNZ(-1) donor set to the nickel ion and on the ease of deprotonation of the extractant. On this basis 3-nitro-4-t-octyl-6-(quinolin-8-imino)phenol is predicted, and is found, to be the strongest Ni-extractant. The extractants have low hydrolytic stability, reverting to their aldehyde precursors when solutions in water-immiscible solvents are contacted with aqueous acid, making them poor candidates for development as reagents for nickel recovery based on pH-swing processes of the type shown above.
Dimethyl sulfoxide as an inducer of differentiation in preosteoblast MC3T3‐E1 cells (2005)

Osteoblastic differentiation is an essential part of bone formation. Dimethyl sulfoxide (DMSO) is a water miscible solvent that is used extensively for receptor ligands in osteoblast studies. However, little is known about its effects on osteoblastogenic precursor cells. In this study, we have used a murine preosteoblast cell line MC3T3-E1 cells to demonstrate that DMSO effectively induces osteoblastic differentiation of MC3T3-E1 cells via the activation of Runx2 and osterix and is dependent upon the protein kinase C (PKC) pathways. We further demonstrated that prolonged activation of PKC pathways is sufficient to induce osteoblastic differentiation, possibly via the activation of PKD/PKCmu.
A Figure of Merit for the Evaluation of Web-Corpus Randomness (2006)

In this paper, we present an automated, quantitative, knowledge-poor method to evaluate the randomness of a collection of documents (corpus), with respect to a number of biased partitions. The method is based on the comparison of the word frequency distribution of the target corpus to word frequency distributions from corpora built in deliberately biased ways. We apply the method to the task of building a corpus via queries to Google. Our results indicate that this approach can be used, reliably, to discriminate biased and unbiased document collections and to choose the most appropriate query terms. 1
Linear prediction on a warped frequency scale (1980)

Linear prediction is considered with respect to a nonlinear frequency scale obtained by a first-order all-pass transformation. The predictor can be computed from a frequency-warped autocorrelation function obtained from the power spectrum or by a direct linear transformation of the original acf. Three numerical procedures are compared. Alternatively, the predictor can be determined from a covariance matrix or (adaptively) from continuously formed correlations, suitably defined according to the all-pass transformation. Prediction-error minimization and spectral flattening are no longer equivalent criteria. In the synthesis part of a vocoder or APC system, no inverse transformation is required, since the direct form of the analysis and synthesis filters can be modified so as to immediately realize the warped transfer function. Single-word intelligibility is compared for a predictive vocoder on a ’’Bark’’ scale and a linear frequency scale. The Bark scale yields results around 90% even at predictor orders of 5 to 7. More possible applications have been given previously by other authors.
Basins of attraction of the bistable region of time-delayed cutting dynamics (2017)

This paper investigates the effects of bistability in a nonsmooth time-delayed dynamical system, which is often manifested in science and engineering. Previous studies on cutting dynamics have demonstrated persistent coexistence of chatter and chatter-free responses in a bistable region located in the linearly stable zone. As there is no widely accepted definition of basins of attraction for time-delayed systems, bistable regions are coined as unsafe zones (UZs). Hence, we have attempted to define the basins of attraction and stability basins for a typical delayed system to get insight into the bistability in systems with time delays. Special attention was paid to the influences of delayed initial conditions, starting points, and states at time zero on the long-term dynamics of time-delayed systems. By using this concept, it has been confirmed that the chatter is prone to occur when the waviness frequency in the workpiece surface coincides with the effective natural frequency of the cutting process. Further investigations unveil a thin "boundary layer" inside the UZ in the immediate vicinity of the stability boundary, in which we observe an extremely fast growth of the chatter basin stability. The results reveal that the system is more stable when the initial cutting depth is smaller. The physics of the tool deflection at the instant of the tool-workpiece engagement is used to evaluate the cutting safety, and the safe level could be zero when the geometry of tool engagement is unfavorable. Finally, the basins of attraction are used to quench the chatter by a single strike, where the resultant "islands" offer an opportunity to suppress the chatter even when the cutting is very close to the stability boundary.
Segmented superconducting tape having reduced AC losses and method of making (2023)

A superconducting tape having reduced AC losses. The tape has a high temperature superconductor layer that is segmented. Disruptive strips, formed in one of the tape substrate, a buffer layer, and the superconducting layer create parallel discontinuities in the superconducting layer that separate the current-carrying elements of the superconducting layer into strips or filament-like structures. Segmentation of the current-carrying elements has the effect of reducing AC current losses. Methods of making such a superconducting tape and reducing AC losses in such tapes are also disclosed.

[Objective assessment of the effect of sodium lauryl sulfate on the surface of the skin in childhood]. (1987)

The influence of sodium lauryl sulfate on physiological properties of the skin surface in children was assessed by continuous measuring of electric conductivity in the course of iontophoresis with physiological solution. The results achieved have shown that even very low concentrations of sodium lauryl sulfate (0.1% water solution) provoke changes of physiological properties in the skin surface. A concentration of 0.5% has been established to be the limit concentration of sodium lauryl sulfate which can evidently injure the barrier functions. The degree of changes in electric conductivity was not dependent on the intensity of the skin irritation.
Seismic imaging of massive sulfide deposits; Part II, Reflection seismic profiling (1996)

Seismic reflection profiling, the dominant geophysical method for hydrocarbon exploration, has the potential to provide images of regional structure for mineral exploration in the crystalline crust and direct detection of large, massive sulfide orebodies. Previous tests of traditional seismic methods in hard-rock environments have had mixed success. Based on these earlier results, we have tailored acquisition and processing strategies to conditions in the Canadian Shield. We illustrate these methods using an example from the Sudbury basin, a rich mineral-producing region. Because of structural complexity that complicates interpretation of the seismic images, the seismic data are integrated with detailed three-dimensional forward modeling based on physical properties studies, mine geology, and well logging. Through this integrated approach, we show that massive sulfides can produce a characteristic seismic reflection response, and that surface seismic reflection profiling may be used to detect and delineate deep, large massive sulfide deposits accurately in a complex geologic setting characterized by moderate dips.
Detecting Alzheimer Disease in Magnetic Resonance Brain Images Using Gabor Wavelets (2007)

A novel method for classification of Magnetic Resonance brain images is presented in this paper. We construct a computational framework for discriminative image feature subspaces. Magnetic Resonance Images of patients in Alzheimer's Disease and normal brain MR images are classified with Support Vector Machines. The framework for the novel method bases on the extraction of gabor features from 2D-Magnetic Resonance images in different scales and orientations. Experiments show that Gabor wavelets can significantly improve classification performance with respect to other popular approaches reported recently in the literature. Combination of gabor features in 3 scales and 8 orientations give 100% classification performance. Experimental results with promising improvements and comparison to related studies are provided.
A Geometric Particle Filter for Template-Based Visual Tracking (2013)

Existing approaches to template-based visual tracking, in which the objective is to continuously estimate the spatial transformation parameters of an object template over video frames, have primarily been based on deterministic optimization, which as is well-known can result in convergence to local optima. To overcome this limitation of the deterministic optimization approach, in this paper we present a novel particle filtering approach to template-based visual tracking. We formulate the problem as a particle filtering problem on matrix Lie groups, specifically the three-dimensional Special Linear group SL(3) and the two-dimensional affine group Aff(2). Computational performance and robustness are enhanced through a number of features: (i) Gaussian importance functions on the groups are iteratively constructed via local linearization; (ii) the inverse formulation of the Jacobian calculation is used; (iii) template resizing is performed; and (iv) parent-child particles are developed and used. Extensive experimental results using challenging video sequences demonstrate the enhanced performance and robustness of our particle filtering-based approach to template-based visual tracking. We also show that our approach outperforms several state-of-the-art template-based visual tracking methods via experiments using the publicly available benchmark data set.
Integrated Temporal Regulation of the Photorespiratory Pathway. Circadian Regulation of Two Arabidopsis Genes Encoding Serine Hydroxymethyltransferase (2000)

The photorespiratory pathway is comprised of enzymes localized within three distinct cellular compartments: chloroplasts, peroxisomes, and mitochondria. Photorespiratory enzymes are encoded by nuclear genes, translated in the cytosol, and targeted into these distinct subcellular compartments. One likely means by which to regulate the expression of the genes encoding photorespiratory enzymes is coordinated temporal control. We have previously shown in Arabidopsis that a circadian clock regulates the expression of the nuclear genes encoding both chloroplastic (Rubisco small subunit and Rubisco activase) and peroxisomal (catalase) components of the photorespiratory pathway. To determine whether a circadian clock also regulates the expression of genes encoding mitochondrial components of the photorespiratory pathway, we characterized a family of Arabidopsis serine hydroxymethyltransferase (SHM) genes. We examined mRNA accumulation for two of these family members, including one probable photorespiratory gene (SHM1) and a second gene expressed maximally in roots (SHM4), and show that both exhibit circadian oscillations in mRNA abundance that are in phase with those described for other photorespiratory genes. In addition, we show that SHM1 mRNA accumulates in light-grown seedlings, although this response is probably an indirect consequence of the induction of photosynthesis and photorespiration by illumination.
Dietary methods in cardiovascular disease critique. (1992)

It is planned that a wide variety of questions related to nutrient intake and cardiovascular disease will be addressed in NHANES III. Given the scope of these questions and the number of different types of designs that may be utilized--cross-sectional, cohort, and case control--several different dietary methodologies will probably be needed within NHANES III. Assessment and ranking of current intake is a primary objective to the overall NHANES III design. The 24-hour recall will provide this assessment and maintain comparability with the previous extensive NHANES. In many instances, however, information on usual intake or past intake will be necessary to better elucidate a nutrient-disease relationship, either because of temporal exposure concerns or because of the variability of the nutrient intake. A food history or quantitative frequency method for the specific nutrient(s) would best address these needs. Information on specific foods or other diet constituents (such as fish, dairy foods, alcohol, or water intake) in addition to nutrient levels will be of interest not only for cardiovascular disease but, with some food items, for cancer and osteoporosis as well. A history or quantitative frequency method would be appropriate for this purpose. The question of serial and multiple measures needs to be addressed. For adequate classification of individuals, several nonconsecutive measures would be most appropriate. The actual number of measures would be determined by the estimate of the most acceptable reduction in variance that could be achieved with multiple measures, balanced by the feasibility and cost of such measures. The use of multiple measures would necessitate the use of alternative interview techniques, most likely by telephone. It is clear that, if this type of methodology is adopted, further validation and extensive pretesting would need to be conducted. A subsample approach could also be utilized. Automated coding of dietary data and computer-prompted immediate data entry interview techniques may facilitate the use of these dietary data collection methods. Whichever methods are utilized, standardization of the coding procedures and additions to the nutrient data base, particularly for sodium, are essential. Finally, there is considerable interest in evaluating any deleterious effects of dietary modification on health and mortality outcome. For example, there is concern that a fat-modified diet may increase cancer mortality in some or that a low-sodium diet may be unpalatable and lead to a lowered dietary intake and potential nutrient deficiencies. It would be useful in this regard for NHANES III to be able to ascertain if altered dietary levels were due to self-selected dietary practices, to prescription of a therapeutic diet, or to a disease state or illness that lowered overall food intake.
Comparison of adherence measurement tools used in a pre-exposure prophylaxis demonstration study among female sex workers in Benin (2020)

With high levels of misreporting of adherence using self-report and pill count, the objective biomedical assessment of adherence via laboratory testing is optimal and more accurately reflects PrEP uptake and persistence. Alternative inexpensive and accurate approaches to monitor PrEP adherence should be investigated.
Load Frequency Control of multi area system using Hybrid Particle Swarm Optimization (2015)

The essential point of the Automatic Generation Control (AGC) is to keep up the system frequency and tie-line power interchange within the limits by controlling the electrical power generated, whenever the fluctuations in the power system occur due to change in load demand. This paper proposes few online smart control techniques to understand the Load Frequency Control (LFC) of multi area system. The main reason to develop smart control techniques to improve the transient response of the power system by reducing the overshoot, undershoot and settling time of the multi area system. The proposed method in this paper is combination of Bacterial Foraging Algorithm (BFA) and Particle Swarm Optimization (PSO) we call it as Hybrid-PSO (H-PSO). The modelling of multi area power system and tuning of the controller are carried out in MATLAB/Simulink environment. After the analysis of results it is observed that H-PSO is better as compare to BFA and PSO.
Literature review of vibrotactile systems addressing freezing of gait in parkinsonians (2017)

Parkinson's Disease is a degenerative neurological disorder of Central Nervous System, which affects the motor and non-motor system and for which there is still no cure. The events of Freezing of Gait are one of the most critical gait impairments and once the medication and the palliative care have not influenced the overcoming of freezing episodes, in the recent years, several non-pharmacological methods have deserved attention. In particular, the vibrotactile feedback systems, have been proven be effective not only in improving the gait of parkinsonians but also in overcoming the freezing episodes Therefore, in this paper, we provide a brief review of the systems and studies performed based in vibrotactile feedback once these methods have proven.

Condition Monitoring and Effective Capacity Improvement for Lithium Polymer Batteries (2019)

This paper proposes a model-based identification method for online monitoring of a state of charge (SOC) and state of health (SOH) of lithium polymer (Li-Po) batteries, which allows a runtime prediction and improves a useful capacity of the aged battery by an internal voltage compensation. For this, the internal resistance of the battery model is frequently updated with the latest estimated data. The algorithm utilizes the measured input current and the battery terminal voltage, where the Sigma-point Kalman filter (SKF) is utilized as an estimation tool. As a result, this scheme offers robustness and high accuracy for estimation under varying operating conditions of the battery. The feasibility of the proposed scheme is validated by the simulation and experimental results. It is shown that the estimation error for the SOC is about 4%.
