Effect on electrospun fibres by synthesis of high branching polylactic acid (2018)

Polylactic electrospun porous fibres have been widely used in tissue engineering scaffolds. However, the application of linear polylactic is limited due to its poor hydrophilicity, which leads to phase separation and has been seldom used in porous fibre preparation. Instead, branching polylactic acts as a new effective method to prepare porous fibres because it can increase polylactic polar property and make it easy to be formulated in the following application. In the current study, we prepared an ultra-high molecular weight of high branching polylactic with glycerol as the initiator by controlling the ring-opening polymerization time, adding amount of catalyst and glycerol. The structure, molecular weight and thermal properties of copolymers were tested subsequently. The result showed that the surface of the high branching polylactic films is smooth, hydrophilic and porous. This branching polylactic formed electrospun porous fibres and possessed a strong adsorption of silver ion. Our study provided a simple and efficient way to synthesize branching polylactic polymer and prepare electrospun porous fibres, which may provide potential applications in the field of biomaterials for tissue engineering or antibacterial dressing compared with the application of linear polylactic and 3-arm polylactic materials.
Adaptive gait algorithm for IWR biped robot (2002)

This paper is concerned with the ZMP (zero moment point) control algorithm for the IWR biped walking robot, which is under development in Korea. The authors introduce a ZMP control method of dynamic biped walking with a special trunk mechanism. The trunk is for balancing during walking, which requires a small balancing space in motion. Walking simulations with the IWR model are shown using the proposed ZMP control method. As a result, the various gaits generation for adapting to the different environments and system stabilization with complex trajectories of swing-leg and support-leg are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Jet Fuel Deoxygenation (1988)

Abstract : This program was initiated to identify and characterize methods of deoxygenating quantities of jet fuel to improve fuel thermal stability. Three methods, chemical getters, molecular sieves and nitrogen sparging, were evaluated in our laboratory. In the case of nitrogen sparging, additional results were obtained by comparing laboratory experimental results with the output from ULLAGE, a computer based mathematical model. Each method was shown to reduce the oxygen content of jet fuel. Economic and system considerations favor nitrogen sparging for large quantities of fuel. Jet fuels, Deoxygenation.
A new capacitive probe for the measurement of high-field domains in Gunn-effect devices (1974)

A new capacitive probe for Gunn-effect domain measurements is reported. The probe was constructed by a vacuum deposition technique rather than the use of thin foils. This results in greatly improved resolution and easier construction.
Division and bit-serial multiplication over GF(qm) (1992)

Division and bit-serial multiplication in finite fields are considered. Using co-ordinates of the supporting elements it is shown that, when field elements are represented by polynomials, division over GF(qm) can be performed by solving a system of m linear equations over GF(q). For a canonical basis representation, a relationship between the division and the discrete-time Wiener-Hopf equation of degree m over GF(q) is derived. This relationship leads to a bit-serial multiplication scheme that can be easily realised for all irreducible polynomials.
Subchronic Toxicity of Ganoderma Lucidum Polysaccharide Peptide (PsP) to Liver Physiology and HistopathologyImaging of Liver on Rattus Norvegicus Strain Wistar Rats (2014)

The current study evaluated the effect of subchronic toxicity of Ganoderma lucidum Polysaccharides peptide (PsP) to liver physiology and histopatology in rats. The 80 rats were randomly divided into four groups male and four groups female (10 rats per group): Three PsP treated group: 300, 600, 1200 mg/KgBW, and one normal control group. Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and Alkaline phosphate (ALP) levels of rats were measured, and histopathology changes: the average of cloudy degeneration, ballooning degenaration, the number of kupfer cell, inflamation cell and necrotizing cell were examinated, after 90 days of treatment with Ganoderma lucidum PsP, the ANOVA test show that AST, ALT and ALP levels of the PsP treated group was not significantly different than the control group, and the histopathology anatomy of the liver wasn’t show any different with the control group. These data suggest that Ganoderma lucidum PsP on all of the 3 doses was not cause any harm effect to liver enzymes neither to liver tissues.
The use of topical subgingival gels of non-steroidal anti-inflammatory drugs (NSAIDs) as an adjunct to non-surgical management of chronic periodontitis. (2009)

The treatment of chronic periodontitis consists of conventional mechanical debridement and removal of plaque and calculus'. Topical NSAIDs could be used to complement the therapy as an adjunct to resolve the inflammatory process and clinical signs of the disease more rapidly. A randomized clinical trial was performed on 33 systemically healthy patients diagnosed with chronic periodontitis, aged 21 to 40 years. All patients underwent scaling and root planing on one quadrant per week, and sub-gingival gel was applied 48 hours after each session. Patients were grouped into 4 treatment protocols with gels containing: (1) placebo, (2) 1% acetyl-salicylic acid (ASA), (3) 1% ketoprofen (KTP) and (4) 2% ketoprofen. The clinical variables studied were: probing depth, attachment level, tooth mobility, plaque index, gingival index and bleeding on probing. All protocols (groups 1, 2, 3 and 4) induced a reduction of probing depths, plaque and gingival indices and bleeding on probing. The 1% ASA and 2% KTP protocols (groups 2 and 4) significantly reduced the probing depth variable (ANOVA p<0.05).

Electrochemically measured porosity of magnetron sputtered TiN films deposited at various substrate orientations (1986)

TiN layers were deposited by magnetron sputtering on polished stainless steel substrates, the position of which was changed in steps from parallel to perpendicular relative to the target surface. Substrate target distance was varied between 25 and 50 mm. Bias current density and substrate temperature at the beginning of deposition were also varied. The porosity of the films deposited under these circumstances was measured by an electrochemical method. The double layer capacity electrolyte/TiN film is a measure of the porosity and the true surface area of the deposited film. Dense films were deposited in all substrate positions when the starting temperature was around 300 °C and the bias current densities were above 2 mA/cm2. With bias current densities below 1 mA/cm2 or no bias and a position of the coated plane perpendicular to the target surface, the true surface of the film is enlarged to 500 times that of the geometrical area of the substrate used. The structural changes responsible for the increase in the porosity are shown in scanning electron microscope (SEM) micrographs.
Immunohistochemical Evaluation of Leptin Expression in Wound Healing (2015)

Leptin has been recognized as an important factor for promoting normal cutaneous wound healing. The aim of this work was to explore leptin expression in keloid and hypertrophic scars (HS) compared with surgical scars and normal skin. The relationship of this expression with clinicopathologic parameters of studied cases was also evaluated. Using immunohistochemical techniques, leptin was analyzed in skin biopsies of 60 nonobese subjects without metabolic syndrome who presented with keloids (20), HS (20), and surgical scars (20). Twenty normal skin samples, from age-matched, sex-matched, and body mass index-matched subjects, were enrolled as a control group. Leptin showed positive immunoreactivity in epidermis in all cases of surgical scars and keloids and in 75% of HS cases. Dermal expression in fibroblasts, inflammatory cells, and endothelial cells was positive in all cases of surgical scars and keloids and in 70% of HS cases. Leptin was overexpressed in keloids and HS compared with normal skin in epidermis (P<0.001 for both) and dermis (P<0.001 for both) and to surgical scars both in epidermis (P=0.0006, P=0.01, respectively) and dermis (P=0.0001, P=0.001, respectively). Higher leptin H score was significantly associated with older age (P=0.02) and positive family history (P=0.002) in keloid cases and with axial site in keloid and HS cases (P=0.001, P=0.02, respectively). Significant positive correlation was noted between epidermal and dermal leptin H scores in keloids (r=+0.37, P=0.04) and HS (r=+0.39, P=0.02). This may be due to epithelial-mesenchymal interactions in scar pathogenesis. In conclusion, in situ leptin overexpression may increase the possibility of keloid and HS occurrence through altered cytokine production and prolonged healing phases with excessive deposition and delayed collagen degradation. This may open an avenue for research for new therapeutic modalities based on its inhibition.
Differential Diagnosis, Investigation, and Current Treatment of Lower Limb Lymphedema (2003)

The common differential diagnosis in Western patients with lower limb swelling is secondary lymphedema, venous disease, lipedema, and adverse reaction to ipsilateral limb surgery. Lymphedema can be confirmed by a lymphoscintigram, computed tomography, magnetic resonance imaging, or ultrasound. The lymphatic anatomy is demonstrated with lymphoscintigraphy, which is particularly indicated if surgical intervention is being considered. The treatment of choice for lymphedema is multidisciplinary. In the first instance, combined physical therapy should be commenced (complete decongestive therapy), with surgery reserved for a small number of cases.
Effects of branched‐chain amino acids on protein turnover (1989)

Amino acid availability rapidly regulates protein synthesis and degradation. Increasing amino acid concentrations above the levels found in post-absorptive plasma stimulates protein synthesis in a dose-dependent manner at the level of mRNA translation-initiation and inhibits protein degradation by inhibiting lysosomal autophagy. The anabolic effects of insulin on protein synthesis and protein degradation are exerted at the same sites (i.e., peptide chain initiation and lysosomal stabilization) allowing for a rapid synergistic response when both amino acids and insulin increase after a protein-containing meal. In perfused liver preparations, protein anabolic effects are exerted by a group of amino acids acting in concert. The BCAA are among the amino acids required for stimulation of hepatic protein synthesis, but there is no evidence that BCAA or leucine alone are effective. Leucine alone is an important inhibitor of hepatic protein degradation, but maximal inhibition requires in addition several other regulatory amino acids. In heart and skeletal muscle in vitro, increasing the concentration of the three BCAA or of leucine alone reproduces the effects of increasing the supply of all amino acids in stimulating protein synthesis and inhibiting protein degradation. Skeletal muscle is the largest repository of metabolically active protein and a major contributor to total body nitrogen balance. Supplying energy alone (i.e., carbohydrate and lipids) cannot prevent negative nitrogen balance (net protein catabolism) in animals or humans; only provision of amino acids allows the attainment of nitrogen balance. In rats and in humans nourished parenterally, provision of balanced amino acid solutions or of only the three BCAA cause similar improvements in nitrogen balance for several days. There is some evidence that infusions of leucine alone can stimulate muscle protein synthesis in vivo; the effect may be transitory and was not observed by all investigators; provisions of excess leucine alone does not seem to affect total body or muscle protein degradation in vivo. In postabsorptive rats, in vivo, infusion of the three BCAA together stimulates muscle protein synthesis as much as the infusion of a complete amino acid mixture or of a mixture of essential amino acids; the in vivo effect requires coinfusion of glucose or of small (physiological) doses of insulin, suggesting synergism between insulin and amino acids.(ABSTRACT TRUNCATED AT 400 WORDS)
Vibrating rf mems technology: fuel for an integrated micromechanical circuit revolution? (2005)

Having produced devices with sufficient Q, thermal stability, and manufacturability, for component-level use in present-day wireless handsets, vibrating RF MEMS technology is now poised to take its next logical steps: higher levels of circuit complexity and integration. In particular, as vibrating RF MEMS devices are perceived more as circuit building blocks than as standalone devices, and as the frequency processing circuits they enable become larger and more complex, the makings of an integrated micromechanical circuit technology begin to take shape, perhaps with a functional breadth to rival that of integrated transistor circuits. This paper suggests the mechanical circuit element properties that ensure a broad functional range for integrated micromechanical circuits.

Mobile applications of focused link discovery (2011)

Abstract Interaction with a mobile device remains difficult due to inherent physical limitations. This difficulty is particularly evident for search, which requires typing. We extend the One-Search-Only search paradigm by adding a novel link-browsing scheme built on top of automatic link discovery. A prototype was built for iPhone and tested with 12 subjects. A post-use interview survey suggests that the extended paradigm improves the mobile information seeking experience.
Experiences in improving introductory physics labs (2018)

I am delighted and impressed by the steps being taken to improve teaching laboratories, as described in “Introductory physics labs: We can do better.” However, I wish that those involved in revising the labs had gone further. Real physics research seeks to answer questions whose answers are not known. All the experiments described in the article have known results, and students could be, and apparently are, given guidance that helps them discover what the professors hope they will conclude. There is only one brief mention—without an example—of students doing experiments in which the result is unknown.Physics tends to simplify systems under investigation in order to seek results that apply with great generality. Conversely, it seems to me that teaching students to think like physicists can be served better by having them work on messy projects with unknown answers.One way to achieve that is to have every student or student group do an experiment that is different from those done by previous students or groups. That sounds impractical, but when I addressed the problem in physics laboratories I was running in Chile 50 years ago, I concluded that it is not difficult. Link the measurements to a local environment. Every simple pendulum behaves like every other simple pendulum, but each person, each pickle, and each piece of popcorn behaves differently from every other person, pickle, and piece of popcorn. So it is not hard to devise experiments to measure the properties or behavior of things in which every case can lead to a different result.

Cancer of the Ovary (2006)

Ovarian cancer is not only the commonest but also the most lethal gynaecological malignancy, partly because the majority of patients present with advanced disease. Nevertheless, the management of patients with ovarian neoplasms has changed substantially recently, with improved survival due to better screening strategies, major advances in chemotherapy and the constantly evolving role of surgery. Optimal patient care is best achieved by a multidisciplinary team, with imaging playing a pivotal role. The explosion of technological developments in imaging in recent years has meant that all members of the team should understand the potential applications, limitations and advantages of evolving imaging techniques. Each volume in Contemporary Issues in Cancer Imaging - A Multidisciplinary Approach is edited by an expert guest editor with contributions from all members of the multidisciplinary team, thus bringing together expertise from many specialties to promote the understanding and application of modern imaging in overall patient management.

Validation of prostate cancer risk variants by CRISPR/Cas9 mediated genome editing (2018)

Abstract GWAS have identified numerous SNPs associated with prostate cancer risk. One such SNP is rs10993994. It is located in the MSMB promoter, associates with MSMB encoded β-microseminoprotein prostate secretion levels, and is associated with mRNA expression changes in MSMB and the adjacent gene NCOA4. In addition, our previous work showed a second SNP, rs7098889, is in LD with rs10993994 and associated with MSMB expression independent of rs10993994. Here, we generate a series of clones with single alleles removed by double guide RNA (gRNA) mediated CRISPR/Cas9 deletions, through which we demonstrate that each of these SNPs independently and greatly alters MSMB expression in an allele-specific manner. We further show that these SNPs have no substantial effect on the expression of NCOA4. These data demonstrate that a single SNP can have a large effect on gene expression and illustrate the importance of functional validation to deconvolute observed correlations. The method we have developed is generally applicable to test any SNP for which a relevant heterozygous cell line is available. Author summary In pursuing the underlying biological mechanism of prostate cancer pathogenesis, scientists utilized the existence of common single nucleotide polymorphisms (SNPs) in human genome as genetic markers to perform large scale genome wide association studies (GWAS) and have so far identified more than a hundred prostate cancer risk variants. Such variants provide an unbiased and systematic new venue to study the disease mechanism, and the next big challenge is to translate these genetic associations to the causal role of altered gene function in oncogenesis. The majority of these variants are waiting to be studied and lots of them may act in oncogenesis through gene expression regulation. To prove the concept, we took rs10993994 and its linked rs7098889 as an example and engineered single cell clones by allelic-specific CRISPR/Cas9 deletion to separate the effect of each allele. We observed that a single nucleotide difference would lead to surprisingly high level of MSMB gene expression change in a gene specific and tissue specific manner. Our study strongly supports the notion that differential level of gene expression caused by risk variants and their associated genetic locus play a major role in oncogenesis and also highlights the importance of studying the function of MSMB encoded β-MSP in prostate cancer pathogenesis.
Murine Coronavirus-Induced Hepatitis: JHM Genetic Background Eliminates A59 Spike-Determined Hepatotropism (2003)

Recombinant murine coronaviruses, differing only in the spike gene and containing the strain A59 (moderately hepatotropic) and JHM (neurotropic) spike genes in the background of the JHM genome, were compared for the ability to replicate in the liver and induce hepatitis in weanling C57BL/6 mice. Interestingly, expression of the A59 spike glycoprotein within the background of the neurotropic JHM strain does not reproduce the A59 hepatotropic phenotype. Thus, the JHM genetic background plays a dominant role over the spike in the determination of hepatotropism.
CALDEP (1985)

Our objective was to develop and validate a regional model for CaCO3 deposition in desert soils of the southwestern United States. There were five major components in the simulation model: a stochastic precipitation model, an evapotranspiration model, chemical thermodynamic relationships, soil parameterization, and a soil water and CaCO3 flux model. For the present climate, a cold-dry Pleistocene climate, and a cool-wet (summer) Pleistocene climate, the model predicted a shallower depth for the calcic horizon than was found in field soils. However, the model was compatible with field soils if one assumed that most pedogenic carbonate formed during a cool-wet (winter) Pleistocene climate. The model was highly sensitive to the frequency of extreme precipitation events and to soil water-holding capacity. The biotic factor played an important role in CaCO3 deposition through its control of soil CO2 concentrations and evapotranspiration rates. The range in predicted CaCO3 deposition rates agreed with the rates for most field studies (1 to 5 g/m2/yr); also, the model predicted an increasing rate of CaCO3 deposition with increasing precipitation, which agreed with field studies. The model is a valuable research tool for evaluating the role of state factors on soil CaCO3 deposition.
Flame Detection with Pruned and Knowledge Distilled YOLOv5 (2021)

Fire is the main disaster that causes economic losses and threats to life safety. The target detector can detect the flame and send an alarm in the early stage of the fire, preventing the deterioration of the fire and causing more losses. Most current target detection models are too large to be deployed on flame detection equipment. In this work, we improved the efficiency of YOLOv5 for real-time flame detection. We pruned the YOLOv5s model at the BatchNormalization (BN) layer, and further distilled the pruned model to fine-tune the accuracy. The compressed YOLOv5s model can reach 76.9% mAP at 44 FPS on our expanded dataset. The accuracy of the compressed model does not decrease compared with the original YOLOv5 model. The Flops is reduced by 54.5%, the parameter amount is reduced by 37.8%, the weight storage file size is reduced by 37.5%, and the inference rate has an increase of four frames per second.
