Mesh-based scalable video coding with rate-distortion optimization (2000)

In this paper, we present a mesh-based motion estimation scheme for image sequence. Nodal motion vectors optimization is performed by using a multi-resolution differential method. Because our final aim is mesh tracking throughout a video sequence with optimized reconstruction, neither backward tracking nor forward tracking is well suited. One motivation of our work is to take advantage of both forward tracking (which enables tracking) and backward tracking (for its efficiency) in a `backward in forward' method. For the optimization of the nodal motion vectors, we also propose a novel approach with multi-resolution and several hierarchy levels, which, in addition, makes it possible scalable representation. This is achieved with a progressive representation defined according to a rate distortion criterion. Results are presented to illustrate the proposed methods.
Kinetic Analysis Of Prothrombin Activation By Des (l-44) Factor Xa (1981)

The region of factor X containing the gla residues was released by mild chymotryptic digestion and the resulting Des (1-44) factor X was converted to its activated form with the Russell’s viper venom factor X activator as described by others. The modified enzyme, factor Xa(-gd), retains its ability to activate prothrombin, the activation was still accelerated by factor Va, but the activation was no longer accelerated by phospholipid. The interaction between factor Va and either factor Xa or factor Xa(-gd) was studied kinetically. The rate of prothrombin activation was measured as a function of increased factor Va concentration in reaction mixtures where the factor Xa or factor Xa(-gd), prothrombin, and Ca2+ concentrations were constant. In the absence of phospholipid, analysis of the above data indicated an apparent dissociation constant (Kd’) of factor Xa for factor Va of 3.6 x 10-8 M. The removal of the gla domain lowered the apparent affinity of factor Xa for factor Va to 2.3 x 10-6 M indicating a role of the gla domain in the factor Xa-factor Va interaction even in the absence of phospholipid. Although the affinity was lowered, the V max of the reaction was identical for factdr Xa and factor Xa(-gd) in the presence of saturating concentrations of factor Va. With the addition of phospholipid, the Kd’ of factor Xa for factor Va was 4.7 x 10-10 M and V max increased some 297 fold. Phospholipid had no effect on the Kd’ of the factor Xa(-gd)-factor Va complex (Kd’ s 2.3 x 10-6 M) and V max was unaltered. These results demonstrate that phospholipid has little or no effect on factor Va function when factor Xa has lost its gla mediated Ca2+ binding sites.
Water‐Soluble Metal Complexes of the Sulfonated Triphenylphosphane TPPTS: Preparation of the Pure Compounds and their Use in Catalysis (1990)

Gel permeation chromatography is the key to isolation of pure TPPTS 1 , as well as the complexes [L X M y (TPPTS) z · (H 2 O) 3z ], for which 1 serves as starting material. These complexes are of considerable interest with respect to homogeneous catalysis, since their water solubility permits them to be separated easily from hydrophobic organic reaction products. Charge concentration around the periphery of the molecule is presumably responsible for the fact that TPPTS complexes such as 2 often display lower coordination numbers than their triphenylphosphane analogues. equation image

Using Simultaneous Confidence Bands to Calculate the Margin of Error in Estimating Typical Biomechanical Waveforms (2022)

Studies of human movement usually collect data from multiple repetitions of a task and use the average of all movement trials to approximate the typical kinematics or kinetics pattern for each individual. Few studies report the expected accuracy of these estimated mean kinematics or kinetics waveforms for each individual. The purpose of this study is to demonstrate how simultaneous confidence bands, which is an approach to quantify uncertainty across an entire waveform based on limited data, can be used to calculate margin of error (MOE) for waveforms. Bilateral plantar pressure data were collected from 70 participants as they walked over 4 surfaces for an average of at least 300 steps per surface. The relationship between MOE and the number of steps included in the analysis was calculated using simultaneous confidence bands, and 3 methods commonly used for pointwise estimates: intraclass correlation, sequential averaging, and T-based MOE. The conventional pointwise approaches underestimated the number of trials required to estimate biomechanical waveforms within a desired MOE. Simultaneous confidence bands are an objective approach to more accurately estimate the relationship between the number of trials collected and the MOE in estimating typical biomechanical waveforms.
A 20-GHz low-noise amplifier with active balun in a 0.25-/spl mu/m SiGe BICMOS technology (2005)

A 20-GHz low-noise amplifier (LNA) with an active balun fabricated in a 0.25-/spl mu/m SiGe BICMOS (f/sub t/=47 GHz) technology was presented by the authors in 2004. The LNA achieves close to 7 dB of gain and a noise figure of 4.9 dB with all ports simultaneously matched to 50 /spl Omega/ with better than -16 dB of return loss. The amplifier is highly linear with an IP/sub 1dB/ of 0 dBm and IIP/sub 3/ of 9 dBm, while consuming 14 mA of quiescent current from a 3.3-V rail, with temperature-compensated biasing. To the authors' knowledge, the LNA delivers the lowest reported noise figure and highest linearity for a silicon implementation of a combined active balun and LNA at 20 GHz, and is the first implementation of an active balun with an LC degenerated emitter-coupled pair. Here we expand on that work, with an analysis of the balun operation and noise optimization of the design.
Proofreading Activity of Pfu Thermostable DNA Polymerase on a 6‐O‐Methylguanine‐Containing Template Monitored by ESI‐FTICR Mass Spectrometry (2004)

Not reading your proofs? Pfu DNA polymerase was able to read through a 6-O-methyl deoxyguanine (6-O-me dG) base during amplification. Products with either cytosine or thymine incorporated on the complementary strand were observed by mass spectrometry (left). The nonproofreading form of the enzyme also produced both product types.
Preparation of Suspensions of Washed Platelets from Humans (1972)

Summary: Methods have been developed for the preparation of suspensions of washed platelets from humans. Heparin is used in the washing fluids to prevent: thrombin generation and apyrase is used to prevent adenine nucleotide accumulation. Platelets suspended in Eagle's tissue culture medium containing albumin were more responsive to ADP than platelets in Tyrode's‐albumin solution. Addition of fibrinogen is required for maximum sensitivity to ADP‐induced aggregation. These platelets can be stored for 4 hr or more at 37°C in the presence of apyrase and maintain their ability to aggregate upon the addition of low concentrations of ADP. Without apyrase the platelets gradually become insensitive to ADP upon storage at 37°C; this is presumably caused by the accumulation of ADP in the suspending fluid because sensitivity can be partially restored by the addition of apyrase and further incubation.
Glycemic control in hospitalized patients not in intensive care: beyond sliding-scale insulin. (2010)

Glycemic control in hospitalized patients who are not in intensive care remains unsatisfactory. Despite persistent expert recommendations urging its abandonment, the use of sliding-scale insulin remains pervasive in U.S. hospitals. Evidence for the effectiveness of sliding-scale insulin is lacking after more than 40 years of use. New physiologic subcutaneous insulin protocols use basal, nutritional, and correctional insulin. The initial total daily dose of subcutaneous insulin is calculated using a factor of 0.3 to 0.6 units per kg body weight, with one half given as long-acting insulin (the basal insulin dose), and the other one half divided daily over three meals as short-acting insulin doses (nutritional insulin doses). A correctional insulin dose provides a final insulin adjustment based on the preprandial glucose value. This correctional dose resembles a sliding scale, but is only a small fine-tuning of therapy, as opposed to traditional sliding-scale insulin alone. Insulin sensitivity, nutritional intake, and total daily dosing review can alter the physiologic insulin-dosing schedule. Prospective trials have demonstrated reductions in hyperglycemic measurements, hypoglycemia, and adjusted hospital length of stay when physiologic subcutaneous insulin protocols are used. Transitions in care require special considerations and attention to glycemic control medications. Changing the sliding-scale insulin culture requires a multidisciplinary effort to improve patient safety and outcomes.

Class II restorations with a polyacid-modified composite resin in primary molars placed in a dental practice: results of a two-year clinical evaluation. (2001)

This study evaluated the two-year success rate of a hybrid composite material (TPH-Spectrum; Dentsply DeTrey, Konstanz, Germany) and a polyacid-modified composite resin (Compoglass, Vivadent, Schaan, Liechtenstein) in Class II restorations placed in primary molars in a dental practice. In each of 52 children, at least two primary molars were restored. Ninety-six primary molars were filled with TPH-Spectrum using the total-etching technique, and 94 with Compoglass without acid etching prior to application of the bonding adhesive. At baseline, one and two years, the restorations were assessed according to the Ryge criteria. Forty-seven children with a total of 132 fillings (68 TPH-Spectrum, 64 Compoglass) were evaluated after two years. The cumulative success rate after 24 months amounted to 89.2% for the Compoglass and 89.7% for the TPH-Spectrum restorations. No significant differences were observed between the two materials with respect to color matching, cavosurface discoloration, anatomic form, margin integrity and caries assessment. This investigation suggests that for a period of two years, the hybrid composite TPH-Spectrum and the polyacid-modified composite resin Compoglass, are suitable materials for restoration of primary molars.
Evaluation of electroluminescence of AlGaN/GaN HEMT on free-standing GaN substrate (2022)

Abstract This paper investigated electroluminescence (EL) in AlGaN/GaN high electric mobility transistors fabricated on a free-standing GaN substrate (GaN-on-GaN) with ones on a SiC substrate (GaN-on-SiC) as a reference. When a drain voltage ( V ds ) of the GaN-on-GaN was increased, the EL peak was kept beside the gate, indicating that the highest electric field region stayed in the vicinity of the gate. On the other hand, EL of the GaN-on-SiC shifted from the gate to the drain electrode under an increased V ds . Our results indicate that the high-electric-field tolerance of GaN-on-GaN is higher than that of GaN-on-SiC, indicating that GaN-on-GaN is more suitable for high-voltage operation.
Choline acetyltransferase activity during postnatal development of the rat heart. (1982)

Choline acetyltransferase (ChAT), the enzyme which catalyze the synthesis of acetylcholine is present in rat heart tissue on the first day of life. ChAT activity increases with age and reaches to a peak of adult level at the age of 40 days. Chat activity was highest in the right atrium then in right ventricle followed by left ventricle and left atrium. These preliminary results suggest that balanced control of the heart by autonomic nervous system is not complete at birth and is at certain risk.
Endoscopic Lothrop Procedure: The University of Miami Experience (1998)

Over a 2-year period, 21 patients with clinical and radiologic evidence of persistent or recurrent frontal sinusitis who had a prior ethmoidectomy and/or frontal sinusotomy underwent an endoscopic Lothrop procedure. The patients' chief complaints were headaches (13), nasal obstruction and/or purulent rhinorrhea (4), orbital abscess/cellulitis (2), anosmia (1), and cough (1). Preoperative frontal headaches were present in 19 patients. The common frontal ostium remained patent (> 50% of intraoperative size) by flexible fiberoptic examination and transillumination 2-24 months postoperatively in 12 of 21 patients (57%). Eighteen of 21 patients (86%) had improved or resolved chief complaints. All but 4 of 19 patients (21%) with preoperative frontal headaches had improved or resolved symptoms. Two patients required additional surgery during the follow-up period. The endoscopic Lothrop procedure is a viable option before frontal sinus obliteration in patients with recurring frontal sinusitis who have failed conventional endoscopic techniques. The surgical technique and results will be presented.
Synthesis of Some Specifically Deoxygenated D-Hexopyranosyl Phosphates (1993)

Abstract A number of diphenyl α-glucopyranosyl and xylopyranosyl phosphates (4, 7, 11. 15, 19, and 25) were prepared from their respective glycosyl chlorides by reaction with silver diphenyl phosphate. These sugar phosphates are of interest as enzyme substrates in deoxy sugar biosynthesis.
Search for High-energy Neutrino Emission from Galactic X-Ray Binaries with IceCube (2022)

Abstract We present the first comprehensive search for high-energy neutrino emission from high- and low-mass X-ray binaries conducted by IceCube. Galactic X-ray binaries are long-standing candidates for the source of Galactic hadronic cosmic rays and neutrinos. The compact object in these systems can be the site of cosmic-ray acceleration, and neutrinos can be produced by interactions of cosmic rays with radiation or gas, in the jet of a microquasar, in the stellar wind, or in the atmosphere of the companion star. We study X-ray binaries using 7.5 yr of IceCube data with three separate analyses. In the first, we search for periodic neutrino emission from 55 binaries in the Northern Sky with known orbital periods. In the second, the X-ray light curves of 102 binaries across the entire sky are used as templates to search for time-dependent neutrino emission. Finally, we search for time-integrated emission of neutrinos for a list of 4 notable binaries identified as microquasars. In the absence of a significant excess, we place upper limits on the neutrino flux for each hypothesis and compare our results with theoretical predictions for several binaries. In addition, we evaluate the sensitivity of the next generation neutrino telescope at the South Pole, IceCube-Gen2, and demonstrate its power to identify potential neutrino emission from these binary sources in the Galaxy.

Structure and biosynthesis of harzianopyridone, an antifungal metabolite of Trichoderma harzianum (1989)

An antifungal metabolite of Trichoderma harzianum has been shown to be (E)-4-hydroxy-6,6-dimethoxy-3-(2-methyl-1-oxohex-4-enyl)pyridin-2-one. The incorporation of [1-13C]- and [1,2-13C2]-acetic acid and [Me-13C]methionine into harzianopyridone and the sites of labelling were established by n.m.r. methods. A low incorporation of [U-14C]aspartic acid was also observed.
The diagnostic performance of neurofilament light chain in CSF and blood for Alzheimer's disease, frontotemporal dementia, and amyotrophic lateral sclerosis: A systematic review and meta‐analysis (2019)

Comparable performance of CSF and blood NfL in many groups demonstrates the promise of NfL as a noninvasive biomarker of neurodegeneration; however, its utility in clinically meaningful scenarios requires greater scrutiny. Toward clinical implementation, a more comprehensive understanding of NfL concentrations in disease subtypes with overlapping phenotypes and at defined stages of disease, and the development of a harmonization program, are warranted.

Undiscovered Physiology of Transcript and Protein Networks (2016)

The past two decades have witnessed a rapid evolution in our ability to measure RNA and protein from biological systems. As a result, new principles have arisen regarding how information is processed in cells, how decisions are made, and the role of networks in biology. This essay examines this technological evolution, reviewing (and critiquing) the conceptual framework that has emerged to explain how RNA and protein networks control cellular function. We identify how future investigations into transcriptomes, proteomes, and other cellular networks will enable development of more robust, quantitative models of cellular behavior whilst also providing new avenues to use knowledge of biological networks to improve human health. © 2016 American Physiological Society.
