A comparison of fracture behavior of nanolaminates with nanocrystals (1999)

Nanocrystalline (Cu-Ag alloy, and Ni) and nanolayered (Cu/Ag and Ni/Cu) structures were produced by electrodeposition techniques. Their microstructure was characterized using TEM methods, and tensile testing was applied to evaluate their mechanical properties. The fracture behavior of these deposits was studied in detail using SEM. The results of this study reveal that for comparable strength levels the single-phase metals fracture by the so-called knife-edge mechanism. However, the laminated structure shows a semi-brittle behavior with evidence of cleavage type fracture. The latter behavior is attributed to the development of high local elastic stresses in the laminated structures.
A Data Collection and Communication Module for Telemedicine and mHealth Systems (2014)

Wearable body sensors have become an important basis for today's medical and fitness applications. To assist athletes or to take care of elderly people in everyday life situations, sensor data can be collected and processed to give helpful feedback. However, the data collection process of multiple o
Endoscopic Surgery for Young Athletes With Symptomatic Unicameral Bone Cyst of the Calcaneus (2011)

Endoscopic curettage and injection of bone substitute appears to be an excellent option for young athletes with symptomatic calcaneal bone cyst for early return to sports activities, because it has the possibility to minimize the risk of postoperative pathologic fracture and local recurrence after early return to initial level of sports activities.
Copolymers with acetyl-protected thiol pendant groups as highly efficient stabilizing agents for gold surfaces (2015)

We showed the potential of novel multifunctional sulfur-containing polymers as model ligands for the preparation of sub-5 nm gold nanoparticles.
Systemic Steroids Suppress Antimelanocyte Antibodies in Vitiligo (1997)

Background: Vitiligo is associated with autoantibodies to melanocytes. The role of these antibodies in the pathogenesis of the disease is still unknown. Objective: The purpose of this study was to examine the role of vitiligo antibodies in the pathogenesis of the disease by studying whether or not there is a correlation between changes in their level and response to therapy with systemic steroid. Methods: Antibodies to the 40 to 45 kD, 75 kD, and 90 kD vitiligo antigens were measured prior to and following systemic steroid therapy in 10 patients with active vitiligo. Results: Four months following initiation of therapy, seven (78%) of nine patients with good clinical response to steroid treatment had a significant decrease in the level of vitiligo antibodies. By contrast, one patient who had no response to treatment had a slight increase in antibody levels. Conclusion: These findings suggest that one mechanism by which corticosteroids can cause repigmentation in vitiligo is by decreasing the level of vitiligo antibodies, and support the notion that vitiligo antibodies are involved in the pathogenesis of this disease.
Renal Tolerance of Gadolinium-DTPA/Dimeglumine in Patients with Chronic Renal Failure (1992)

Safety data for renal tolerance of gadolinium-DTPA(Gd-DTPA)/dimeglumine were evaluated in 21 patients (age: mean +/- standard deviation [SD], 58 +/- 12 years) with impaired renal function. The mean +/- SD serum creatinine level at baseline was 213 +/- 101 mumol/L (range, 89.2-551 mumol/L). Creatinine clearance at baseline averaged 34.5 +/- 19.2 mL/minute (range, 7.2-70 mL/minute). Gd-DTPA was injected at a dose of 0.1 mmol/kg body weight. Serum parameters (creatinine, sodium, and potassium) were determined before and 6, 24, 48, and 120 hours after administration of Gd-DTPA. Urinary parameters (N-acetyl-beta-D-glucosaminidase [beta-NAG], protein, and albumin) were determined before (spot urine sample) and after treatment for collection periods 0 to 3, 3 to 6, 6 to 12, 12 to 24, and 24 to 48 hours. A final spot urine sample was taken at 120 hours. There was no significant statistical change of serum creatinine level within the observation period, and there was no single patient matching the criteria of acute renal failure (increase of serum creatinine level of 88.4 mumol/L [1 mg/dL] or more within 48 hours after injection). Serum values of sodium and potassium levels remained unchanged. Beta-NAG was slightly increased 0 to 3 hours after injection, but returned to baseline values during the collection periods up to 120 hours. There was no increase of protein or albumin excretion. These preliminary results suggest Gd-DTPA has good renal tolerance in patients with pre-existing chronic renal failure.
Effect of Additives on the Performance of PPBES Composite Forward Osmosis Hollow Fiber Membranes (2020)

A polyamide composite forward osmosis (FO) hollow fiber membrane was successfully prepared with a novel copoly(phthalazinone biphenyl ether sulfone) (PPBES) polymer. Effects of different additives including ethylene glycol methyl ether (EGME) and lithium chloride anhydrous (LiCl) in the dope solution on the morphologies and properties of PPBES support membranes and composite FO hollow fiber membranes were investigated. With the increase of EGME content in the dope solution, the water flux of PPBES support membranes and FO hollow fiber membranes decreased. When LiCl was added into the dope solution, the water flux of FO hollow fiber membranes improved significantly with the increase of LiCl content. Additionally, the FO performance of the PPBES membrane was further optimized by adding triethylamine (TEA) in the interfacial polymerization (IP) process. In comparison with other FO membranes, the novel PPBES composite FO hollow fiber membrane displayed a remarkably high water flux of 45.3 L/m<sup>2</sup> h and a low specific reverse salt flux of 0.15 g/L.
Coronary artery quantitation and data management system for paired cineangiograms (1991)

A computerized system designed to optimize the quantitation of coronary vessels on 35 mm cineangiograms is described and validated. Because the system has two cine film digitizers, it processes paired coronary arteriograms for the evaluation of serial changes in coronary arteries. A database system was specifically designed for the storage of coronary artery quantitation data which resides on a file server in a local area network and may be accessed by multiple workstations. In radiographic phantom studies of nine contrast-filled lucite cylinders of known size, the overall accuracy and precision for the measured diameters were 0.069 mm and 0.066 mm respectively. Measurements of minimum diameter and percent diameter stenosis of 21 coronary lesions selected from 17 routine cineangiograms showed high degree of intraobserver and interobserver reproducibility.
The PMI Predictor - a Web App Enabling Green-by-Design Chemical Synthesis (2019)

Herein we describe a green-by-design approach to route selection and development, assisted by predictive analytics and historical data. In order to aid the selection of more efficient strategies, we created a user-friendly web application, the “PMI Prediction Calculator,” to foretell the probable efficiencies of proposed synthetic routes, prior to their evaluation in the laboratory. This tool can also be used to benchmark the outcome performance of a developed process. We expect that use of this app will bring greater awareness of sustainability during the ideation phase of route design and will contribute to a reduced environmental impact of pharmaceutical production. The app can be accessed following the link:https://acsgcipr-predictpmi.shinyapps.io/pmi_calculator/
Integrated thermal-electrical-optical simulator of vertical-cavity surface-emitting lasers (1999)

An integrated thermal-electrical-optical solver of vertical- cavity surface-emitting lasers has been developed on the basis of the effective frequency method combined with the rate equations for photon and carrier densities. The integrated solver is applied to analyze the performance characteristics of GaAs-based proton-implanted top-surface- emitting lasers, oxide-confined surface-emitting lasers and intracavity-contacted oxide-confined surface-emitting lasers. Numerical results confirm the experimentally observed significant advantage of oxide-confirmed structures over proton-implanted devices, and identify the intracavity- contacted design as the most advantageous for oxide-confined structures.
Regulation of SFRP-1 Expression in the Rat Dental Follicle (2012)

Tooth eruption requires osteoclastogenesis and subsequent bone resorption. Secreted frizzled-related protein-1 (SFRP-1) negatively regulates osteoclastogenesis. Our previous studies indicated that SFRP-1 is expressed in the rat dental follicle (DF), with reduced expression at days 3 and 9 close to the times for the major and minor bursts of osteoclastogenesis, respectively; but it remains unclear as to what molecules contribute to its reduced expression at these critical times. Thus, it was the aim of this study to determine which molecules regulate the expression of SFRP-1 in the DF. To that end, the DF cells were treated with cytokines that are maximally expressed at days 3 or 9, and SFRP-1 expression was determined. Our study indicated that colony-stimulating factor-1 (CSF-1), a molecule maximally expressed in the DF at day 3, down-regulated SFRP-1 expression. As to endothelial monocyte-activating polypeptide II (EMAP-II), a highly expressed molecule in the DF at day 3, it had no effect on the expression of SFRP-1. However, when EMAP-II was knocked down by siRNA, the expression of SFRP-1 was elevated, and this elevated SFRP-1 expression could be reduced by adding recombinant EMAP-II protein. This suggests that EMAP-II maintained a lower level of SFRP-1 in the DF. TNF-α is a molecule maximally expressed at day 9, and this study indicated that it also down-regulated the expression of SFRP-1 in the DF cells. In conclusion, CSF-1 and EMAP-II may contribute to the reduced SFRP-1 expression seen on day 3, while TNF-α may contribute to the reduced SFRP-1 expression at day 9.
Oral tongue cancer in young adults less than 40 years of age: Rationale for aggressive therapy (1994)

Squamous cell carcinoma (SCC) of the oral tongue in patients less than 40 years old is a rare but aggressive disease. Published reports suggest poor overall treatment results for young patients despite relatively early stage disease presentation. A 25-year review of the English language literature (1968 to 1993) identifies 14 reports with 3 or more patients younger than 40 years of age with SCC of the oral tongue. Of 152 cases identified, 57% of patients developed locoregional failure and 47% of patients died secondary to their cancer. At the University of Wisconsin Hospital and Clinics, 6 patients under the age of 40 years have received treatment between 1971 and 1991 for SCC of the oral tongue. Despite presentation with relatively early stage disease, 5 of 6 patients have developed locoregional failure and 4 patients have died from their cancer. These results for the younger population reflect a higher locoregional failure and mortality rate than representative reports from the older population. An aggressive therapeutic approach to the young patient with SCC of the oral tongue appears warranted in an attempt to improve locoregional control and ultimate survival.
Nuclear Magnetic Resonance Studies of Tertiary Phosphines Adducts with Titanium Tetrachloride, using 1H and 31P (1971)

Abstract Proton and 31 P NMR. spectra in solution of several TiCl 4 PR 3 systems have been measured at variable temperatures. The results suggest the presence of fast equilibria in solution involving 1:1 and 1:2 adducts, and free tertiary phosphine. In addition there is evidence for the probable existence, at low temperature, of binuclear species of the type Ti 2 Cl 8 (PR 3 ). Correlations are found between the 31 P chemical shifts for the 1:1 adducts on the one hand, and Taft 's constants and half‐neutralisation potentials on the other. Some new 1:1 and 1:2 TiCl 4 PR 3 adducts have been isolated and have been characterised by analysis and infrared spectroscopy.
Quantification of Cyclosporin A in Human Cerebrospinal Fluid by Liquid Chromatography‐Mass Spectrometry using Atmospheric Pressure Chemical Ionization (2007)

Abstract Cyclosporin A (CsA) is widely used as an immunosuppressant in organ transplantation, and the treatment of autoimmune disorders. This is the first publication describing a rapid, sensitive, and selective liquid chromatography‐mass spectrometry (LC‐MS) method for analysis of CsA in cerebrospinal fluid (CSF). Chromatographic separation was achieved using a reversed‐phase column with a linear gradient mobile phase. A column switching procedure was incorporated to minimize contamination in the ion source of the mass spectrometer. The sample volume requirement was 50 µL and no internal standard was employed. Quantification was carried out with selected ion reaction (SIR) monitoring of the protonated sodium ion adduct (m/z=1224.7). Calibration curves were linear from 0.5 ng/mL to 20 ng/mL with a weighting factor of 1/x. Precision and accuracy, and reverse predicted concentration residuals were within 15%. The method has been used successfully for the analysis of CSF samples from a clinical study.
Attention M-net for Automatic Pixel-Level Micro-crack Detection of Photovoltaic Module Cells in Electroluminescence Images (2020)

In the solar power industry, quality inspection of solar cells is a very important part of the production and application process. Micro-crack is a type of common defect that may be present in photovoltaic (PV) module cells which can reduce the power generation efficiency and service lifetime. However, it is difficult to identify micro-crack by the naked eye because it is readily confused with non-uniform backgrounds and complex textures in Electroluminescence (EL) images. In this paper, we propose Attention M-net which combines efficient segmentation model structure and attention mechanism. It is a novel micro-crack detection model for automated pixel-level micro-crack detection of PV module cells. The M-shaped structure solves "All Black" issue that is easy to occur due to the severe imbalance of the micro-crack segmentation dataset. And integration of attention mechanism into the network significantly improves the accuracy of segmentation. Because of the above two advantages, the proposed model can be accurately learned from a small annotated dataset, thereby saving the time of micro-crack EL images collection and pixel-level annotations. We extensively trained the proposed model on a small dataset of 20 annotated EL images which include 10 monocrystalline and 10 polycrystalline. The evaluated results on the test dataset demonstrate the high efficiency and accuracy of Attention M-net for pixel-level micro-crack detection of PV module cells in EL images.

Increase of Traction Coefficient by Means of Microtexture (2nd Report, Optimization of Parameter in Microtexture and Application to Actual CVT) (2008)

The first report describes longitudinal surface texture was the best for improving the traction coefficient. Therefore, the longitudinal surface texture was optimized using the 4-roller tester. The test results made it clear that the groove depth, groove pitch and also the radius of curvature of the convex portion of the rolling elements are important parameters of the longitudinal grooves for improving the traction coefficient while assuring high durability at the same time. Furthermore, an attempt was made of increase traction coefficient of an actual CVT variator by using an optimized longitudinal surface texture. The test result proves that a traction coefficient can be improved by optimizing microtexture without spoiling durability.
Quantitative Fluorescence Image Analysis in Bladder Cancer Screening (1990)

Quantitative fluorescence image analysis (QFIA) cytology combines image analysis to measure DNA with visual cytology for bladder cancer detection. QFIA sensitivity is 76% to 81% and 95% to 100% for low- and high-grade tumors respectively, with 94% specificity in asymptomatic controls. QFIA screening of 504 persons within a beta-naphthylamine exposed cohort found DNA hyperploidy correlated with the duration of carcinogenic exposure and smoking history; marker prevalence was 23% for exposed workers who smoked and 2% for nonexposed nonsmokers. In prospective animal studies, QFIA was useful in monitoring carcinogenesis and chemoprevention with retinoids. Current QFIA research focuses on measurements of oncogenes, growth factors and their receptors, cytoskeleton, and tumor-associated antigens to improve sensitivity and specificity to low-grade tumors and to identify premalignant conditions. Profiles of biochemical and immunological markers on single cells may further assist in the study of high-risk cohorts and individual risk assessment.
Metallic nanostructures as electronic billiards (2021)

Optical properties of the metallic nanoparticles are most often described in terms of plasmons, that is, coupled states of light and electrons. Here we show that many discrete resonances, resulting from the quantum confinement of electronic wavefunctions inside the metallic nanostructure, may lead to a single strong composite resonance, located typically in the low-frequency (mid-infrared and terahertz) range. They give rise to strong nonlinearities allowing efficient generation of terahertz and mid-infrared frequencies on the distances of just hundred nanometers. Especially effective are the processes which couple the quantum-confinement-induced resonances with Mie-type ones.
Assignments of Carbon-Sulphur Vibrations by Selenation: An FT-IR and FT-Raman Study on 1, 3, 5-Trithiacyclohexane (1996)

Abstract The IR and Raman spectra of 1, 3, 5-trithiacyclohexane (1) and 1, 3, 5-triselenocyclohexane (2) have been recorded with FT-instrumentation within 3500–100 cm−l, and the C-S vibrations of 1 have been reviewed by comparing its spectra with those of 2. The IR and Raman spectra slightly differ from those previously reported and some vibrations, previously assigned to C-H modes in 1on the basis of NCT calculations, are reassigned to C-S modes on the basis of the selenation effect. “Selenation” has proved to be a very simple and effective tool in recognizing carbon-sulfur vibrations both in IR and Raman. The Raman peaks due to carbon-chalcogen vibrations are less intense in 1 than in 2, according to the higher polarizability of the selenium atom.
Reasoning training in veteran and civilian traumatic brain injury with persistent mild impairment (2015)

Traumatic brain injury (TBI) is a chronic health condition. The prevalence of TBI, combined with limited advances in protocols to mitigate persistent TBI-related impairments in higher order cognition, present a significant challenge. In this randomised study (n = 60), we compared the benefits of Strategic Memory Advanced Reasoning Training (SMART, n = 31), a strategy-based programme shown to improve cognitive control, versus an active learning programme called Brain Health Workshop (BHW, n = 29) in individuals with TBI with persistent mild functional deficits. Outcomes were measured on cognitive, psychological health, functional, and imaging measures. Repeated measures analyses of immediate post-training and 3-month post-training demonstrated gains on the cognitive control domain of gist reasoning (ability to abstract big ideas/goals from complex information/tasks) in the SMART group as compared to BHW. Gains following the SMART programme were also evident on improved executive function, memory, and daily function as well as reduced symptoms associated with depression and stress. The SMART group showed an increase in bilateral precuneus cerebral blood flow (CBF). Improvements in gist reasoning in the SMART group were also associated with an increase in CBF in the left inferior frontal region, the left insula and the bilateral anterior cingulate cortex. These results add to prior findings that the SMART programme provides an efficient set of strategies that have the potential to improve cognitive control performance and associated executive functions and daily function, to enhance psychological health, and facilitate positive neural plasticity in adults with persistent mild impairment after TBI.
AC Response to Humidity and Propane of Sprayed Fe-Zn Oxide Films (2009)

Iron-zinc oxide films with different Zn contents were ultrasonically sprayed on glass substrates and inter-digital gold electrodes were evaporated on them. Films were deposited from solutions containing 2, 10 and 30 at.% Zn. Hematite, amorphous and Franklinite structures resulted, respectively. They were assessed as humidity and propane detectors under alternating-current conditions for frequencies from 1 to 10(5) Hz and two temperatures: 30 and 250°C. Their impedances in dry air, humid air and humid air plus propane were determined from voltage measurements with a Lock-In amplifier. Sensitivity values to both humidity (53% RH.) and 189, 500 and 786 ppm of propane from the response of the real and imaginary parts of the impedance and also the total impedance were determined as functions of frequency. Maximum sensitivity for each case and the corresponding frequency are reported. The maximum sensitivity to humidity ranges from 24% up to 308%. In the case of propane, the maximum sensitivity ranges from 45% up to 711%. The largest sensitivity values correspond in all cases to the imaginary part of the impedance. From the dynamical response, the response and recovery times are determined, along with the concentration-dependence of the sensitivity. The sensing mechanisms are also discussed.
