Presence, Actions, and Regulation of Myostatin in Rat Uterus and Myometrial Cells (2008)

Myostatin, a member of the TGF-beta superfamily of proteins, is known to suppress skeletal muscle mass and myocyte proliferation. The muscular component of the uterus is the myometrium, a tissue that regulates its mass in response to different physiological conditions under the influence of sex steroids. Recently, our laboratory reported effects of activin-A, another TGF-beta family member, on signalling and proliferation of rat uterine explants and human myometrial cell lines in culture. Here, we explore the expression, actions, and regulation of myostatin in uterine smooth muscle. Myostatin mRNA was demonstrated to be expressed in a myometrial cell line, pregnant human myometrial 1 cell line (PHM1). Functional assays showed that myostatin induced phosphorylation of Smad-2 and reduced proliferation of PHM1 number in a time and dose-dependent manner. Furthermore, myostatin activated smad-2 specific signalling pathways in rat uterine explants. To expand on our in vitro findings, we found that myostatin is expressed in rat uterus and determined that myostatin mRNA expression varies as a function of the phase of the estrous cycle. Uterine levels of myostatin peaked during late estrus and were the lowest at proestrus. Ovariectomy increased myostatin expression; estrogen treatment strongly decreased myostatin levels, whereas progesterone weakly decreased myostatin expression. In conclusion, myometrial cells are myostatin sensitive, myostatin mRNA levels are modulated in vivo in rats during the estrous cycle, and in response to steroid deprivation and replacement.
A Review: DWT-DCT Technique and Arithmetic-Huffman Coding based Image Compression (2015)

Nowadays, the volume of the data is increasing with time which generates a problem in storage and transfer. To overcome this problem, the data compression is the only solution. Data compression is the science (or an art) of representing information in compact form. This is an active research area. Compression is to save the hardware storage space and transmission bandwidth by reducing the redundant bits. Basically, lossless & lossy are two types of data compression technique. In lossless data compression, original data is similar to decompressed or decoded data, but in lossy technique is not same. In this paper, Study lossless image compression technique. The purpose of image compression is to maximum bandwidth utilization and reduces storage capacity. This technique is beneficial to image storage and transfer. At the present time, Mostly image compression research have focused on the wavelet transform due to better performance over another transform. The performance is evaluated by using MSE & PSNR. DWT, quantization, Arithmetic, Huffman coding and DCT techniques are briefly introduced. After decompression, the quality of image is evaluated using PSNR parameter between original & decoded image. Compression ratio (CR) parameter is calculated to measure how many times image compressed.
High-Speed Similarity-Based Image Retrieval with Data-Alignment Optimization Using Self-Organization Algorithm (2009)

In a retrieval system for vast amounts of image data, the primary storage cannot hold all image feature vectors because a huge data capacity would be required. Therefore, it is necessary to handle a slow-access secondary storage effectively as well as a first-access primary storage. In this paper, we propose a data-alignment optimization method in the secondary storage to access fast. Our idea is based on the premise that similar data have a high probability of simultaneous access in a similarity-based retrieval system. Then, we approximate the secondary storage by one dimensional alignment and allocates similar data to closer regions in the alignment. It is regarded as an optimization problem for a one-dimensional alignment that enables a fast retrieval by reducing a seek range. Through the experiments for 5 millions dataset, we confirmed that the data access time was reduced by 25.3% compared to no data-alignment optimization, which contributed significantly to speeding up the entire retrieval process.
Decision Level Fusion: An Event Driven Approach (2018)

This paper presents a technique that combines the occurrence of certain events, as observed by different sensors, in order to detect and classify objects. This technique explores the extent of dependence between features being observed by the sensors, and generates more informed probability distributions over the events. Provided some additional information about the features of the object, this fusion technique can outperform other existing decision level fusion approaches that may not take into account the relationship between different features.
The Reliability of Visual Performance Measures in Low Vision (1995)

The reliability of measurements of visual performance of subjects with low vision may be expected to be worse than the reliability of subjects with 'normal' vision. Whilst this is commonly accepted in clinical practice, there have been no studies which have demonstrated this effect. This is of practical significance as it is important to know the expected variance in performance to be able to determine what is a 'real' change from the usual measurement noise. In low vision there is often the requirement to monitor on-going ocular disease, and often this involves assessment of vision.
Syntheses, Structures and Properties of Two Cd(II) Complexes Based on the 2-(1H-Imidazol-1-yl-methyl)-1H-benzimidazole Ligand (2012)

Two new 1-D Cd(II) complexes, {[Cd(imb)(μ 2 -Cl)Cl]·CH 3 OH}n (1) and {[Cd(imb)(μ 2 - Cl)Cl]·DMF} n (2), have been synthesized by the reactions of the unsymmetrical ligand 2-(1Himidazol- 1-yl-methyl)-1H-benzimidazole (imb) with CdCl 2 ·2.5H 2 O in methanol or methanol=DMF solution at room temperature, and structurally characterized by single-crystal X-ray diffraction. Complex 1 displays a ladder-shaped chain in which [Cd 2 Cl 4 ] units are linked to each other through two bridging imb ligands. Complex 2 features an infinite looped chain structure composed of two kinds of rings, the smaller [Cd 2 Cl 2 ] ring and the larger [Cd 2 imb 2 ] ring, connected alternately via their Cd(II) ions. The different architectures of complexes 1 and 2 can be generated by solvent exchange. The IR spectra and fluorescence properties of the complexes have been also investigated.
Immunoperoxidase detection of 8-hydroxydeoxyguanosine in aflatoxin B1-treated rat liver and human oral mucosal cells. (1996)

An immunoperoxidase method using a monoclonal antiserum that recognizes 8-hydroxydeoxyguanosine has been developed for detection and quantitation of oxidative damage in single cells. The method was initially applied to cultured cells treated with H2O2 or aflatoxin B1 and then to cryostat liver sections of rats treated with aflatoxin B1. To demonstrate that the method has sufficient sensitivity for detection of damage in human samples, oral mucosal cells from a total of 12 pairs of smokers and nonsmokers were analyzed. Mean staining intensity of oral cells of smokers was 1.6-fold higher than in nonsmokers. The immunoperoxidase method, requiring a small number of cells and eliminating the need for isolation of DNA, will be useful for evaluation of oxidative damage in a wide range of biological samples.
Atomic interferometry using stimulated Raman transitions (1991)

Sodium atoms prepared in hyperfine ground-state 11 &gt; are driven to the other ground-state hyperfine level 12&gt; when two laser beams nearly resonant with an optical transition have a frequency difference equal to the ground-state hyperfine splitting. When the two laser beams are counterpropagating, conservation of momentum between the atom and the light field requires that the atom acquire a velocity kick ~2 2 ħk/m during the 11&gt; and 12&gt; transition (~6 cm/sec in our experiment). When the lasers are detuned far from the optical transition, spontaneous emission from the intermediate optical level becomes negligible, and the atom behaves as a two-level system coupled to a resonant rf driving field. We have created an interferometer by applying a π/2-π-π/2 Raman pulse sequence: a first π/2 pulse coherently splits the atomic wave packet by putting it in a superposition of states 11&gt; and 12&gt;, a second π pulse occurring a time Δ t later redirects each wave packet and a final π/2 pulse recombines the wave packets at time 2Δ t . We have observed wave packet interference for wave packet separations of 2.4 mm and, by using the interferometer as an accelerometer, have measured the atom’s acceleration due to gravity to 3 parts in 10 6 .
Practical aspects of intensive insulinization in the intensive care unit (2007)

Attainment and preservation of glycemic control among critically ill patients are best attempted with intravenous insulin infusion. Advances in the design of decision support and insulin delivery systems, and progress in the technology of continuous blood glucose monitoring, are likely to reduce the risk of hypoglycemia, without compromise of target range control, such that the patient outcomes enjoyed by experienced centers in the future will prove generalizable to others through the extension of new technologies.
Robust Statistical Parity-Time Symmetric Lasers in Fiber Cavities (2016)

We demonstrate that many features of PT-symmetric lasing, such as the lower predicted lasing threshold and PT-symmetric phase transition, are sufficiently robust to be observed in a long fiber cavity (&gt;1 km) despite random phase fluctuations.
The Role of Jones Matrices in Critical Dimension Computation for Immersion Lithography (2006)

The effect of polarization changes through an immersion lithographic projection lens on image critical dimension is examined. Ignoring these polarization changes in imaging models produces errors in prediction of across-field behavior and lens tolerance analysis.
A Clinically Relevant Frailty Index for Aging Rats (2017)

Frailty is a clinical syndrome that is increasingly prevalent during aging. Frailty involves the confluence of reduced strength, speed, physical activity, and endurance and is associated with adverse health outcomes. The present study adapts existing clinical and preclinical indices of frailty to the Fischer (F344) rat. Male F344 rats (n = 133; 17 mo) completed a battery of behavioral tasks, including forelimb wire suspension (strength), rotarod (speed), open field (physical activity), and inclined screen (endurance). Rats that performed poorly (lowest quintile) on two tasks were considered mildly frail (17.29%, n = 23), and rats that performed poorly on 3-4 tasks were considered frail (2.26%, n = 3). Logistic regression of 100-day survival revealed that mildly frail rats were 3.8 times and frail rats were 27.5 times more likely to die during that period than nonfrail rats (p = .038; 95% confidence interval: 2.030, 372.564). The selected criterion tests, cutoff points, and index provide a potential tool for identifying frailty in aged F344 rats, which is consistent with existing frailty indices for humans and mice.

High hardenability ferrous powders for p/m forgings (1977)

Powder metallurgy forgings prepared from experimental ferrous Mn-0.7% Mo-0.9% Ni, Mn-1% Mo-1% Ni, and 1% Mo-1% Ni powders were compared with forgings of type 4600 alloy powder at 0.15 to 0.20% carbon content. Forgings produced from preforms sintered either in hydrogen at 1230 C (2250 F) or in endothermic gas at 1120 C (2050 F) were evaluated for end-quench hardenability, Charpy impact resistance and fracture toughness (K/sub Ic/). The Mn-0.7% Mo-O.9% Ni powder is equal in hardenability to the 4600 powder. The Mn-1% Mo-1% Ni powder is somewhat higher in hardenability, being approximately equal to a conventional wrought SAE 8800 steel of equivalent carbon content. The toughness properties of the experimental powder forgings compared favorably with those of the 4600 forgings, with the Charpy energy being slightly higher for the 4600 forgings and the K/sub Ic/ values being slightly higher for the experimental powder forgings.

Naphthalenetetracarboxylic Diimide-Based n-Channel Transistor Semiconductors:  Structural Variation and Thiol-Enhanced Gold Contacts (2000)

The synthesis and field-effect transistor (FET) electron mobility of ten N-substituted naphthalene 1,4,5,8-tetracarboxylic diimide (NTCDI) derivatives deposited at ambient and elevated temperatures are reported. Mobilities >0.01 cm2/(V s) were measured in air for three NTCDIs with partially fluorinated substituents, and >0.001 cm2/(V s) for a hydroxy-terminated compound. Mobilities 0.001−0.1 cm2/(V s) were also found for three n-alkyl NTCDIs, but only under vacuum; FET operation with gold bottom contacts was enabled by specific thiol coatings of the contacts. The highest mobility in air, >0.1 cm2/(V s), was conferred by 4-trifluoromethylbenzyl substitution, while 1H,1H-perfluorooctyl substitution resulted in an on/off ratio in air >105. Solution electrochemistry and solid-state X-ray and electron diffraction were employed to partially explain the results, and applications of the materials to complementary circuits are considered.
Analysis of small-angle scattering data from block copolymer micelles using models based on Monte Carlo simulations (2005)

Numerous studies of block copolymer micelles formed in selective solvent by scattering methods have been published in the literature. In order to extract information on the structure of the micellar core and corona, modelling is required. Recently, there has been a large progress in the model expressions available for the analysis of such scattering data. The expressions are based on results from Monte Carlo simulations on models with a compact core and a corona of interacting, self-avoiding chains. During the simulations, both scattering form factors and the real-space structure are sampled, so that various semi-empirical expressions can be tested. When established, these expressions can be used in the analysis of experimental scattering data. An overview of the developments is given and the application to micelles of the diblock copolymer Brij700 (C 18 EO 100 ) in water (D 2 O) solution is presented. The micelles consist of a hydrophobic core surrounded by a corona of PEO chains in contact with the solvent. SAXS and SANS experiments are combined to provide complementary information. Both the effect of concentration and temperature are investigated, where the latter parameter induces a change of solvent quality for the PEO chains.
Exploring closed-loop feedback control using experiments in optics (2001)

We present two experiments in closed-loop feedback control. In the first experiment, students control the pointing angle of a laser to "lock" the laser onto a "target." In the second, students stabilize the pathlength difference in two arms of a Michelson interferometer. These experiments are appropriate for electronics and optics laboratory classes for junior and senior level students.

Universal Solid-Phase Reversible Sample-Prep for Concurrent Proteome and N-Glycome Characterization (2016)

We describe a novel solid-phase reversible sample-prep (SRS) platform that enables rapid sample preparation for concurrent proteome and N-glycome characterization for nearly all protein samples. SRS utilizes a uniquely functionalized, silica-based bead that has strong affinity toward proteins with minimal to no affinity for peptides and other small molecules. By leveraging this inherent size difference between proteins and peptides, SRS permits high-capacity binding of proteins, rapid removal of small molecules (detergents, metabolites, salts, peptides, etc.), extensive manipulation including enzymatic and chemical treatments on bead-bound proteins, and easy recovery of N-glycans and peptides. SRS was evaluated in a wide range of samples including glycoproteins, cell lysate, murine tissues, and human urine. SRS was also coupled to a quantitative strategy to investigate the differences between DU145 prostate cancer cells and its DIAPH3-silenced counterpart. Previous studies suggested that DIAPH3 silencing in DU145 induced transition to an amoeboid phenotype that correlated with tumor progression and metastasis. In this pilot study we identified distinct proteomic and N-glycomic alterations between them. A metastasis-associated tyrosine kinase receptor ephrin-type-A receptor (EPHA2) was highly up-regulated in DIAPH3-silenced cells, indicating a possible connection between EPHA2 and DIAPH3. Moreover, distinct alterations in the N-glycome were identified, suggesting cross-links between DIAPH3 and glycosyltransferase networks.
A New NMR Method of Fluid Characterization in Reservoir Rocks: Experimental Confirmation and Simulation Results (2001)

Summary This paper introduces a new magnetic resonance fluid (MRF) characterization method. The MRF method is based on two key ingredients—a new microscopic constituent viscosity model (CVM) and a new multifluid relaxation model. The CVM provides a link between nuclear magnetic resonance (NMR) relaxation times and molecular diffusion coefficients in hydrocarbon mixtures such as crude oils. The multifluid relaxation model accounts for the T2 decay of spin-echo signals that arises from intrinsic spin-spin interactions, surface relaxation, and attenuation due to molecular diffusion of fluid molecules in a magnetic field gradient. The MRF method exploits the fact that the molecular diffusion coefficients of brine, oil, and gas molecules typically have values that are well separated from one another. Thus, the diffusion attenuation of a suite of measured NMR signals contains sufficient information to allow differentiation of brine, oil, and gas. The method involves the simultaneous inversion of a suite of spin-echo measurements with the new MRF multifluid relaxation model. The application of the MRF method to magnetic resonance logging data can provide a detailed formation evaluation. The information provided includes total porosity, bulk volume of irreducible water, brine and hydrocarbon saturation, hydrocarbon-corrected permeability, and oil viscosity. This paper discusses the theory underlying the CVM and validates the model by testing its predictions on hydrocarbon mixtures including live and dead crude oils. The robustness and accuracy of the multifluid inversion is demonstrated by a Monte Carlo simulation of a model carbonate rock that contains brine, oil, gas, and oil-base mud filtrate (OBMF). The MRF method is applied to suites of spin-echo measurements acquired in the laboratory on partially saturated rocks and shown to provide accurate fluid saturation and oil viscosity estimates. Since the completion of this work, field test results have shown that the MRF method provides a powerful and unique new formation evaluation tool.
An on-board pedestrian detection and warning system with features of side pedestrian (2012)

Automotive Active Safety(AAS) is the main branch of intelligence automobile study and pedestrian detection is the key problem of AAS, because it is related with the casualties of most vehicle accidents. For on-board pedestrian detection algorithms, the main problem is to balance efficiency and accuracy to make the on-board system available in real scenes, so an on-board pedestrian detection and warning system with the algorithm considered the features of side pedestrian is proposed. The system includes two modules, pedestrian detecting and warning module. Haar feature and a cascade of stage classifiers trained by Adaboost are first applied, and then HOG feature and SVM classifier are used to refine false positives. To make these time-consuming algorithms available in real-time use, a divide-window method together with operator context scanning(OCS) method are applied to increase efficiency. To merge the velocity information of the automotive, the distance of the detected pedestrian is also obtained, so the system could judge if there is a potential danger for the pedestrian in the front. With a new dataset captured in urban environment with side pedestrians on zebra, the embedded system and its algorithm perform an on-board available result on side pedestrian detection.
Sol‐gel immobilization of serine proteases for application in organic solvents (2001)

The serine proteases alpha-chymotrypsin, trypsin, and subtilisin Carlsberg were immobilized in a sol-gel matrix and the effects on the enzyme activity in organic media are evaluated. The percentage of immobilized enzyme is 90% in the case of alpha-chymotrypsin and the resulting specific enzyme activity in the transesterification of N-acetyl-L-phenylalanine ethyl ester with 1-propanol in cyclohexane is 43 times higher than that of a nonimmobilized lyophilized alpha-chymotrypsin. The activities of trypsin and subtilisin Carlsberg are enhanced with 437 and 31 times, respectively. The effect of immobilization on the enzyme activity is highest in hydrophobic solvents.
