Detection of Construction Workers in Video Frames for Automatic Initialization of Vision Trackers (2012)

Vision based tracking can provide the spatial location of construction entities such as equipment, workers, and materials in large scale, congested construction sites. It tracks entities in video streams by inferring their locations based on the entities' visual features and motion histories. To initiate the process, it is necessary to determine the pixel areas corresponding to the construction entities to be tracked in the following consecutive video frames. In order to fully automate the process, an automated way of initialization is needed. This paper presents the method for construction worker detection which can automatically recognize and localize construction workers in video frames. The method first finds the foreground areas of moving objects using a background subtraction method. Within these foreground areas, construction workers are recognized based on the histogram of oriented gradients (HOG) and histogram of the HSV colors. HOG's have proved to work effectively for detection of people, and the histogram of HSV colors helps differentiate between pedestrians and construction workers wearing safety vests. Preliminary experiments show that the proposed method has the potential to automate the initialization process of vision based tracking.
Excess Noise In Carbon Nanotubes (2005)

The excess noise of single‐walled carbon nanotubes is studied over the 77K to 300K temperature range. Lorentzian shaped spectra along with 1/f noise spectra are observed. From the Lorentzian noise components activation energies of 0.21 and 0.46eV for the associated fluctuation mechanisms are obtained.
The cytosolic isoenzyme of 3‐deoxy‐D‐arabino‐heptulosonate 7‐phosphate synthase in Spinacia oleracea and other higher plants: extreme substrate ambiguity and other properties (1992)

The cytosolic isoenzyme of 3‐deoxy‐D‐arabino‐heptulosonate 7‐phosphate (DAHP) synthase (DS‐Co: EC 4.1.2.15) in Spinacia oleracea, Solanum tubersosum and many other higher plants was found to use a diversity of substrates. Diose (glycolaldehyde), triose (D‐glyceraldehyde, L‐glyceraldehyde and DL‐glyceraldehyde 3‐phosphate), tetrose (D‐erythrose, L‐erythrose, D‐erythrose 4‐phosphate, D‐threose and L‐threose), and pentose (D‐ribose 5‐phosphate and D‐arabinose 5‐phosphate) were utilized in combination with phosphoenolpyruvate (PEP) to make the corresponding 2‐keto‐3‐deoxy sugar acids. Glyoxylate was also utilized by DS‐Co. Glycoladehyde exhibited the highest reaction velocity when substrates were tested at 3 m M concentrations. Pentoses were poor substrates except when phsophorylated, an effect which is probably due to an increased fraction of the molecules being in the open‐chain form. Little stereoselective discrimination exists since comparable velocities were demonstrated with the D and L isomers of glyceraldehyde, erythrose or threose. The enzyme is not a reversible aldolase since pyruvate failed to substitute for PEP. The use of D‐erythrose 4‐phsophate or glycolaldehyde resulted in K m values of 1.95 m M and 8.60 m M , respectively. However, glycolaldehyde exhibited the largest V max K m ratio, suggesting a greater catalytic efficiency for this substrate. Glycolaldehyde is an ideal substrate for inexpensive assays of DS‐Co that are absolutely selective in the presence of two other plant enzymes which also utilize erythrose 4‐phosphate and PEP. The spinach DS‐Co enzymes required divalent metals for activity. The presence of 20 m M Mg 2+ , 1 m M Co 2+ and 1 m M Mn 2+ yielded relative activities of 100, 70 and 15, respectively. The pH optimum was 9.5 and temperature optimum for activity was 49°C. The molecular masses of DS‐Co from spinach, tobacco and pea were all in the range of 400 kDa. The possible roles of DS‐Co in biosynthesis of α‐ketoglutarate and aromatic amino acids, in biosynthesis of components of cell wall and phytotoxin, and in acting as a sink for 2‐and 3‐carbon sugars are discussed.

Ninth Symposium of the Japanese Arsenic Scientists' Society (JASS‐9), 20–21 November 1999, Hiroshima, Japan (2001)

46 papers were presented, including two special lectures on clinical aspects of acute arsenic poisoning, one given by Professor Naohide Inoue of Kyushu University, and the other, on arsenic metabolism in acute arsenic poisoning in patients including toxicological considerations, given by Professor Hiroshi Yamauchi, St Marianna University School of Medicine.In these symposia, a variety of researchers in fields such as medicine, pharmacology, chemistry, biology, engineering, environmental science, mar-ine science and agriculture have communicated their advances in arsenic research.The increasing interest in arsenic is indicated by the fact that more than 210 researchers attended this Ninth Symposium.
High-efficiency silicon solar cells (1984)

Silicon solar cells are described which operate at energy conversion efficiencies independently measured at 18.7 percent under standard terrestrial test conditions (AM1.5, 100 mW/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , 28°C). These are apparently the most efficient silicon cells fabricated to date. The high-efficiency results from a combination of high open-circuit voltage due to the careful attention paid to the passivation of the top surface of the cell; high fill factor due to the high open-circuit voltage and low parasitic resistance losses; and high short-circuit current density due to the use of shallow diffusions, a low grid coverage, and an optimized double layer antireflection coating.
Analysis and Correction of a Pantograph Location Method Based on Current Information of Traction Network (2021)

To address the power interruption and the speed loss caused by neutral sections in ac electrified railway, many ground-charged auto-passing neutral section devices have been proposed recently. For these devices, the accurate positioning of trains is necessary and important. An automatic pantograph location technique based on voltage and current signals is analyzed ideally in our preceding research. However, according to the experimental data in practical railway, the positioning accuracy may be seriously affected by the actual configuration of catenaries and feeders. It is reported in this article that the circulating current in the neutral section loop is the cause to induce the above issue. Thus, the pantograph location method based on the current information of traction network is deeply analyzed, and a mathematical model with consideration of mutual inductance is built, which can explain the mechanism of the circulating current. Furthermore, an adaptive correction method based on experimental tests is proposed to ensure the positioning accuracy. Through the ground-charged auto-passing neutral section device commissioned in the Shenshuo heavy-haul railway in China, the correctness of the theoretical analysis and the effectiveness of the proposed correction method are verified. This article provides an important guideline for the application of this pantograph location method.

Prediction of Clinical Outcome Using Gene Expression Profiling and Artificial Neural Networks for Patients with Neuroblastoma (2004)

Currently, patients with neuroblastoma are classified into risk groups (e.g., according to the Children's Oncology Group risk-stratification) to guide physicians in the choice of the most appropriate therapy. Despite this careful stratification, the survival rate for patients with high-risk neuroblastoma remains <30%, and it is not possible to predict which of these high-risk patients will survive or succumb to the disease. Therefore, we have performed gene expression profiling using cDNA microarrays containing 42,578 clones and used artificial neural networks to develop an accurate predictor of survival for each individual patient with neuroblastoma. Using principal component analysis we found that neuroblastoma tumors exhibited inherent prognostic specific gene expression profiles. Subsequent artificial neural network-based prognosis prediction using expression levels of all 37,920 good-quality clones achieved 88% accuracy. Moreover, using an artificial neural network-based gene minimization strategy in a separate analysis we identified 19 genes, including 2 prognostic markers reported previously, MYCN and CD44, which correctly predicted outcome for 98% of these patients. In addition, these 19 predictor genes were able to additionally partition Children's Oncology Group-stratified high-risk patients into two subgroups according to their survival status (P = 0.0005). Our findings provide evidence of a gene expression signature that can predict prognosis independent of currently known risk factors and could assist physicians in the individual management of patients with high-risk neuroblastoma.
Clinical impact of CREDO-kyoto risk score on in-hospital bleeding in patients with acute coronary syndrome (2021)

Abstract Background/Introduction CREDO-Kyoto bleeding risk score was developed to predict the post-discharge bleeding events in patients with percutaneous coronary intervention. However, there were limited reports of the effectiveness of this score to predict the in-hospital bleeding events in patients with acute coronary syndrome (ACS). Methods We evaluated 562 consecutive ACS patients in Saga university hospital between 2014 and 2019. Primary outcome was major bleeding during hospitalization. Major bleeding was defined as the GUSTO moderate/severe bleeding. Patients were classified into three groups according to the CREDO-Kyoto bleeding risk score (low, intermediate and high). Results Major bleeding events occurred in 12.1% of all patients during hospitalization. Patients in the high risk group (n=22) had significantly higher incidence of major bleeding than those in the intermediate (n=113) and the low risk groups (n=427) (22.7%, 18.6%, versus 9.8%, respectively, p=0.018, see figure). Multivariate analysis showed that intermediate and high risk groups were independent predictors for the in-hospital major bleeding. Conclusions CREDO-Kyoto risk score successfully identified high risk ACS patients for the major bleeding during hospitalization. Funding Acknowledgement Type of funding sources: None. Results
Suppression of Natural Killer Cell Activity and Promotion of Tumor Metastasis by Ketamine, Thiopental, and Halothane, but Not by Propofol: Mediating Mechanisms and Prophylactic Measures (2003)

This study in a rat model of pulmonary metastasis demonstrates that some anesthetics, but not others, increase susceptibility to tumor metastasis, apparently by suppressing natural killer cell activity. Ketamine was most deleterious, and its effects were prevented by peripheral blockade of beta-adrenoceptors combined with low levels of immunostimulation.
Deployable origami Yagi loop antenna (2015)

A Yagi loop antenna, which is built on an origami spring structure, is presented here. The Yagi loop array can be compressed to 5 cm length by a servo motor which can reduce nearly 70% of the volume of the array. The antenna's body is 20.5 cm long when it is expanded to the working state. The physical parameters of the antenna such as loop's radius and distances between loops are analyzed. The antenna is designed to work at 1.31 GHz. A directional realized gain of 10.4 dBi is observed. The measurements agree well with the designed simulation model.
Carnitine levels in normal children and adults and in patients with diseased muscle (1980)

An assay for evaluating carnitine levels in normal children and adults is described. After a 12-hour period of fasting, individual variations in 24-hour urinary excretion of carnitine were observed in adults. In children, there was a significant decrease in excretion from the 10th month to the third year, and then an increase until the 10th year. There was no significant difference between children and adults in the serum and skeletal muscle levels. Muscle carnitine levels were also studied in 12 cases of lipid-storage myopathy and in cases of other muscle diseases, including Duchenne muscular dystrophy in children.

The Role of Hydrogen Peroxide in Environmental Adaptation of Oral Microbial Communities (2012)

Oral streptococci are able to produce growth-inhibiting amounts of hydrogen peroxide (H(2)O(2)) as byproduct of aerobic metabolism. Several recent studies showed that the produced H(2)O(2) is not a simple byproduct of metabolism but functions in several aspects of oral bacterial biofilm ecology. First, the release of DNA from cells is closely associated to the production of H(2)O(2) in Streptococcus sanguinis and Streptococcus gordonii. Extracellular DNA is crucial for biofilm development and stabilization and can also serve as source for horizontal gene transfer between oral streptococci. Second, due to the growth inhibiting nature of H(2)O(2), H(2)O(2) compatible species associate with the producers. H(2)O(2) production therefore might help in structuring the initial biofilm development. On the other hand, the oral environment harbors salivary peroxidases that are potent in H(2)O(2) scavenging. Therefore, the effects of biofilm intrinsic H(2)O(2) production might be locally confined. However, taking into account that 80% of initial oral biofilm constituents are streptococci, the influence of H(2)O(2) on biofilm development and environmental adaptation might be under appreciated in current research.
Dynamic force spectroscopy of parallel individual Mucin1–antibody bonds (2005)

We used atomic force microscopy to measure the binding forces between Mucin1 (MUC1) peptide and a single-chain variable fragment (scFv) antibody selected from a scFv library screened against MUC1. This binding interaction is central to the design of molecules used for targeted delivery of radioimmunotherapeutic agents for prostate and breast cancer treatment. Our experiments separated the specific binding interaction from nonspecific interactions by tethering the antibody and MUC1 molecules to the atomic force microscope tip and sample surface with flexible polymer spacers. Rupture force magnitude and elastic characteristics of the spacers allowed identification of the rupture events corresponding to different numbers of interacting proteins. We used dynamic force spectroscopy to estimate the intermolecular potential widths and equivalent thermodynamic off rates for monovalent, bivalent, and trivalent interactions. Measured interaction potential parameters agree with the results of molecular docking simulation. Our results demonstrate that an increase of the interaction valency leads to a precipitous decline in the dissociation rate. Binding forces measured for monovalent and multivalent interactions match the predictions of a Markovian model for the strength of multiple uncorrelated bonds in a parallel configuration. Our approach is promising for comparison of the specific effects of molecular modifications as well as for determination of the best configuration of antibody-based multivalent targeting agents.
Protection of Neurovascular Injury by Vasoprotective Agents: A Novel Therapeutic Strategy for Ischemic Brain Edema (2010)

The blood-brain barrier (BBB) in brain microvessels maintains homeostasis of the brain microenvironment mostly through maintenance of tight junctions between brain vascular endothelial cells, thereby preventing passage of hydrophilic molecules or toxic substances from the blood to the brain. Vascular damage following embolic stoke leads to disruption of BBB, thereby eliciting brain edema. Therefore, microvascular endothelial cell is likely potential therapeutic target to rescue neurons from brain edema. Vasoprotective agents such as free radical scavengers, matrix metalloproteinase inhibitors and HMGCoA reductase inhibitors are potential candidates to inhibit BBB disruption. In this review, we focus on mechanisms of decreased brain infarction by these vasoprotective agents. In addition, nitric oxide and peroxynitrite are known to elicit cerebral microvascular injury resulting BBB disruption following cerebral ischemia. Of note, inhibition of nitric oxide synthase (NOS) attenuates BBB disruption following brain ischemia. We recently introduced a novel vasoprotective drug, DY-9760e, which is a novel calmodulin-dependent NOS inhibitor. We confirmed that DY-9760e, can protect microvascular endothelial cells in rat embolic stoke model, thereby attenuating BBB disruption. Taken together, we propose a therapeutic modality that target cerebrovascular would represent powerful approaches to prevent brain edema following cerebral ischemia.
Thin-film UV VCSELs and LEDs by electrochemical etching (2022)

We will give an overview of state-of-the-art results and challenges to achieve high-performing III-nitride vertical-cavity surface-emitting lasers (VCSELs), with a particular focus on the requirements to push the emission wavelength into the ultraviolet (UV). Our method to simultaneously achieve high-reflectivity mirrors and good cavity length control by electrochemical etching enabled the world’s first UV-B VCSEL. The use of dielectric mirrors yielded lasers with a very temperature-stable emission wavelength thanks to the negative thermo-optic coefficient of the mirrors. We have used the same etch methodology to also lift-off fully processed LEDs from their growth substrate to improve the light extraction efficiency.

Fabrication of organic interfacial layers by molecular layer deposition: Present status and future opportunities (2013)

To keep pace with the miniaturization of next generation devices in applications such as electronics, biotechnology, and energy, their constituent polymer thin films must meet challenging requirements such as providing simultaneously ultrathin and conformal coatings. Traditional polymer deposition methods may not be suitable, and as a result, new fabrication methods are needed. Molecular layer deposition (MLD), as an analog to atomic layer deposition, provides precise control over many polymer film properties, such as thickness, composition, morphology, and conformality. Hence, MLD can be a powerful and novel method for fabrication of polymer films. This review article introduces the variety of polymer films that have been developed using MLD together with important film growth characteristics and properties. Examples of MLD polymer applications are provided as well. Finally, challenges and outlooks of the MLD technique are discussed.
Successful treatment of AIDS-related pulmonary Kaposi's sarcoma with liposomal daunorubicin (1994)

We report a 35 year old male, human immunodeficiency virus (HIV)-infected patient with acquired immune deficiency syndrome (AIDS), who presented with rapidly progressive pulmonary Kaposi's sarcoma. The tumour regressed with treatment with liposomal daunorubicin and remained in partial remission until the patient died 12 months later from complications of HIV infection. Liposomal daunorubicin may be a safe and effective alternative to the treatment protocols in current use for pulmonary Kaposi's sarcoma.
Verapamil therapy in infants with hypertrophic cardiomyopathy (1998)

We sought to evaluate the safety and efficacy of acute and chronic treatment with verapamil in infants with hypertrophic cardiomyopathy. Prior studies have shown an improvement in adults with hypertrophic cardiomyopathy who were treated with verapamil. Acutely, it reduced the degree of left ventricular outflow tract obstruction. Chronic therapy was associated with an improvement in symptoms and increased long-term survival. To date, no data are available on the efficacy of this drug in infants with hypertrophic cardiomyopathy. We evaluated prospectively the safety and efficacy of verapamil in infants. The acute and chronic effects of verapamil on infants with an echocardiographic diagnosis of hypertrophic cardiomyopathy were evaluated at a single institution between 1980 and 1994, with long-term follow-up available until 1996. Acute effects of an intravenous bolus of 0.1 mg/kg and infusion at 0.007 mg/kg/min were evaluated, where possible, in the cardiac catheterization laboratory. Oral verapamil at 3-5 mg/kg/day was started after catheterization. Follow-up included serial clinical, echocardiographic and Holter monitoring. A total of 22 patients were studied, 17 having a presumed diagnosis of primary hypertrophic cardiomyopathy including three with Noonan's syndrome. Acute infusion of the drug was well tolerated by all, without adverse electrophysiological effects. Haemodynamic effects were consistent with a negative inotropic action with significant falls in cardiac index (4.6+/-1.2 to 4.1+/-0.9 l/min/m2), systolic blood pressure (88+/-16 to 82+/-14 mmHg) and gradient across the left ventricular outflow tract (nine patients 48.2+/-30.4 to 28.4+/-24.1 mmHg). End-diastolic pressure was unchanged (14.0+/-6.8 to 13.9+/-4.7 mmHg). Three patients with primary hypertrophic cardiomyopathy died (two while being treated). In the group with primary hypertrophic cardiomyopathy continuing with long-term treatment, follow-up revealed regression in two, progression in three (two died) and stability in 10. For those treated, there was a trend towards improvement in clinical status. Verapamil is well tolerated acutely in infants with hypertrophic cardiomyopathy. The outcome was considerably better in these patients compared with prior reports, though careful long-term assessment is needed.

Sintering densification curve: A practical approach for its construction from dilatometric shrinkage data (2008)

This article summarizes the usage of high-temperature dilatometry in ceramic processing and powder technology with special attention on the description of the sintering process. A practical method for transformation of dilatometric shrinkage data into densification curves (the dependence of the sample density on sintering temperature or time) is described in detail. A new automatic procedure to recalculate sintering shrinkage data allowing the plot of the densification curve has been developed, which is presented here.
