A study of electric power quality using storage system in distributed generation

This paper describes a method to improve the power quality of a distributed generation (DG) power system. The proposed method uses a power storage system with DG. Here, DG is assumed the renewable energy systems such as photovoltaic generation (PV), wind power generation (WG) and fuel cells (FC), etc. The effect to use the storage battery is shown by the following two experiments. One case is the examination of a power transmission simulator. Another case is an experiment in a small-scale actual system. The electric power quality (frequency, voltage) is observed, when the storage battery have been introduced or not. In case of a power transmission simulator, the frequency control is executed using two methods; a power demand estimation method and a proportion control method that uses frequency deviation. The control of the storage battery is executed by using these controls. Another case is an examination for a real power system, which is the 12th pavilion of Aichi Institute of Technology (AIT). In this pavilion, photovoltaic generation (PV), wind power generation (WG) and storage batteries have been introduced. And the electric power is supplied by these sources. The electric power qualities in two cases were compared. One case is the storage battery is introduced. Another case is without the storage battery. The storage battery executes the control that maintains the voltage in the power system. As a result, it has been understood that the electric power quality has improved, when the storage battery is introduced.
Neuroinflammation in glaucoma: soluble tumor necrosis factor alpha and the connection with excitotoxic damage

Inflammation is a complex and highly regulated response that occurs early after infection or injury. This process is initiated by cells of the immune system to re-establish tissue homeostasis. When the injury is persistent, however, chronic inflammation leads to overproduction of noxious mediators that contribute to cell dysfunction and death. The inflammatory response in the central nervous system (CNS), known as neuroinflammation, is achieved by activation of resident glia and monocyte-derived cells. Accumulating evidence indicates that this cellular response occurs in the early stages of numerous neurodegenerative diseases, triggering a cascade of events that converge to promote neuronal damage. Indeed, neuroinflammation has been reported in a host of CNS disorders including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, multiple sclerosis, stroke, and glaucoma.
Normal Production of Human Chorionic Gonadotropin in Perimenopausal and Menopausal Women and After Oophorectomy

Background: The normal pituitary production of human chorionic gonadotropin (hCG) alongside luteinizing hormone, and its presence in women after bilateral oophorectomy, during perimenopause and menopause, as measured in serum and urine, has been known for 30 years and is described in numerous publications. Last year our group discussed this finding in a correspondence to the editor in the March 15th issue of New England Journal of Medicine, yet the misinterpretation of low-level hCG in these women seems to have increased in magnitude. Methods: This is an outcomes study of 36 cases of menopausal hCG referred to the USA hCG Reference Service over a 1-year period, from March 2007 to March 2008. Results: Eight cases occurred in women after oophorectomy, 28 were women in menopause/perimenopause. Surgery was postponed in 5 (14%) of 36 cases, and in 3 cases (8%), chemotherapy was unnecessarily administered. In 2 cases, computed tomography scans were cancelled. The average hCG detected was 10 ± 7.2 IU/L in cases receiving an oophorectomy and 9.8 ± 6.7 in perimenopause and 11 ± 6.2 IU/L in menopause cases. Conclusions: Low-level hCG production in woman in physiologic perimenopause, in menopause, or in women with prior bilateral oophorectomy is a normal biologic and biochemical phenomenon. Management protocols in all fields need to be changed to accept pituitary hCG as normal and recognize the clinical maneuvers that will secure the diagnosis. Understanding this physiology will avoid needless delays in necessary therapies such as organ transplant procedures and will limit the misadventure of prescribing unnecessary cancer treatments.
Statistical characterization of the UWB propagation channel in indoor residential environment

This paper presents a statistical characterization of an ultra wideband (UWB) indoor propagation channel based on measurements conducted in various types of high-rise apartments in several cities of Korea. Measurements were carried out in the frequency band of 3–10 GHz. Various communication links were considered including both line-of-sight (LOS) and non-LOS (NLOS) scenarios, which covered within-the-room and room-to-room propagations. The measurement procedure allows us to characterize both the large-scale and the small-scale statistics of the channel. The aim here is to study in more detail the statistical characteristics of the UWB propagation channel and to provide insight for future statistical channel modeling work. Channel characteristics examined include the distance and frequency dependency of path loss, shadowing fading statistics, and multipath temporal-domain parameter statistics such as the mean excess delay, RMS delay spread, and the number of dominant paths.

Tidal flow over three‐dimensional topography generates out‐of‐forcing‐plane harmonics

We conduct laboratory experiments and direct numerical simulations on internal gravity waves generated by tidal flow over a model three‐dimensional Gaussian mountain on the sea floor. When 2ω < N (where ω is the tidal frequency and N is the buoyancy frequency), the flow generates second harmonic internal waves that propagate perpendicular to the tidal forcing direction. These unexpected harmonics are observed only when the maximum slope of the bottom topography is greater than the slope of internal wave propagation. The out‐of‐plane harmonics saturate at a higher tidal forcing amplitude than the normal in‐tidal‐forcing‐plane harmonics, and could lead to increased wave breaking and mixing near rough topography in the ocean.
T-DNA Tagging: A Promising Tool for Functional Genomics in Medicinal Plants

Nowadays, herbal medicines have been widely used in health care and disease treatment and the share of herbal medicinal products in pharmaceutical market is increasing rapidly in many countries. One of the main resources of active pharmaceutical ingredients of herbal medicines is secondary metabolites, many of which are structurally complex and difficult to synthesize chemically. Thus, increasing the yield of some secondary metabolites through bioengineering approaches is highly desired. However, it is difficult to achieve at present because the genetic background of most medicinal plants is not clear and the genes involved in the biosynthesis of secondary metabolites are largely unknown. Intensive studies on functional genomics in medicinal plants seem to be a key for solving this problem.
A comparison of once-daily and divided doses of modafinil in children with attention-deficit/hyperactivity disorder: a randomized, double-blind, and placebo-controlled study.

OBJECTIVE This randomized, double-blind, placebo-controlled study assessed the efficacy and tolerability of several modafinil dosing regimens in children with attention-deficit/hyperactivity disorder (ADHD) to determine whether modafinil can be given once daily in pediatric ADHD. METHOD Children and adolescents (age range, 6-13 years) (N = 248) with DSM-IV-defined ADHD were enrolled in a 4-week, double-blind, placebo-controlled study, conducted February-May 2002. The group was assigned to receive oral (100-mg tablets) modafinil 300 mg once daily (300 mg in the morning followed by placebo at midday), modafinil 300 mg as a divided dose (100/200 mg or 200/100 mg), or matching placebo. In children weighing > or = 30 kg, a higher dose of 400 mg (200/200 mg) was evaluated. Efficacy measures included the teacher-rated School Version and clinician-rated Home Version of the ADHD Rating Scale-IV and the parent-completed Conners' ADHD/DSM-IV Scales. RESULTS 223 children completed the study. Those who received modafinil 300 mg once daily showed a significantly greater improvement (change from baseline) than those who received placebo in symptoms of ADHD across all rating scales and subscales (all p < .05). Divided 300-mg doses of modafinil provided some significant but inconsistent improvements in ADHD symptoms. In children weighing > or = 30 kg, modafinil 400 mg (200/200 mg) was significantly superior to placebo on clinician- and parent-completed scales (all p < .05). Insomnia was the only adverse event to occur with significantly greater frequency in a modafinil group (200/100) than in the placebo group (14% vs. 2%) (p = .03). CONCLUSION Modafinil significantly improved ADHD symptoms in children. Once-daily dosing (300 mg) provided the most consistent improvement in symptoms. All dosing regimens of modafinil were well tolerated.
An Estimation Method of Surface Defects of LMJ Microshells

Abstract This paper presents the development of a radiographic characterization method for microshells. In the Laser MegaJoule (LMJ) framework, microshells are tiny plastic spheres used in inertial fusion laser experiments. For this work, these microshells were characterized using low-energy radiography. In the microshell radiographs, phase contrast was noted at the edges of the microshells. The origin of this phenomenon has been identified as sharp variation of gray-scale amplitude due to refraction. Our theoretical model links pixel information with microshell geometry and is used for contour detection and characterization. Finally, an estimation of surface defects described by spherical harmonics is calculated.
Trading Off Test Coverage and False Reject Risk of Self-Calibrating Self-Test Systems

Self-calibrating systems are becoming more popular as increasing variability in shrinking geometries demands compensating techniques. Comparator based self-calibration is the most common base for self-compensating circuits due to its minimum overhead. If a self-test feature is added, care must be taken that the tails of the calibrated distribution are not causing false rejects. This paper presents the implementation and verification of an ultra-low current reference which is self-calibrated and self-tested. By introducing two independent unit test elements, instead of one fixed test element of 1.5 LSB, more headroom for distribution tails is gained. Using a simple fault model of the trim DAC, the paper investigates the trade-off between test coverage and the risk of false rejects.
Role of Plk2 (Snk) in Mouse Development and Cell Proliferation

ABSTRACT Plk2 (Snk) is a polo-like kinase expressed at G1 in cultured cells and mainly in the hippocampal neurons in the brains of adult rodents, but its function is poorly understood. We have generated mice deficient in Plk2 by gene targeting. Although Plk2 is not required for postnatal growth, Plk2−/− embryos show retarded growth and skeletal development late in gestation. The labyrinthine zone of the placenta is diminished in Plk2−/− embryos due to decreased cell proliferation. Cultured Plk2−/− embryonic fibroblasts grow more slowly than normal cells and show delayed entry into S phase. These data suggest a role for Plk2 in the cell cycle.
The freeze on mass media campaigns in England: a natural experiment of the impact of tobacco control campaigns on quitting behaviour.

AIMS To measure the impact of the suspension of tobacco control mass media campaigns in England in April 2010 on measures of smoking cessation behaviour. DESIGN Interrupted time series design using routinely collected population-level data. Analysis of use of a range of types of smoking cessation support using segmented negative binomial regression. SETTING England. MEASUREMENTS Use of non-intensive support: monthly calls to the National Health Service (NHS) quitline (April 2005-September 2011), text requests for quit support packs (December 2007-10) and web hits on the national smoking cessation website (January 2009-March 2011). Use of intensive cessation support: quarterly data on the number of people setting a quit date and 4-week quitters at the NHS Stop Smoking Services (SSS) (quarter 1, 2001 and quarter 3, 2011). FINDINGS During the suspension of tobacco control mass media spending, literature requests fell by 98% [95% confidence interval (CI) = 96-99], and quitline calls and web hits fell by 65% (95% CI = 43-79) and 34% (95% CI: 11-50), respectively. The number of people setting a quit date and 4-week quitters at the SSS increased throughout the study period. CONCLUSIONS The suspension of tobacco control mass media campaigns in England in 2012 appeared to markedly reduce the use of smoking cessation literature, quitline calls and hits on the national smoking cessation website, but did not affect attendance at the Stop Smoking Services. Within a comprehensive tobacco control programme, mass media campaigns can play an important role in maximizing quitting activity.
Range-Doppler radar sensor fusion for fall detection

Falls are the major cause of accidents in the elderly population. Propelled by their non-intrusive sensing capabilities and robustness to heat and lighting conditions, radar-based automated fall detection systems have emerged as a candidate technology for reliable fall detection in assisted living. The use of a multiple radar system, in lieu of a single radar unit, for indoor monitoring combats occlusion and supported by the fact that motion articulations in the directions away from the line of sight generate weak Doppler signatures that are difficult to detect and classify. Fusion of the data from two radars is deemed to improve performance and reduce false alarms. Utilizing two 24 GHz ultra-wide band (UWB) radar sensing systems, we present different fusion architectures and sensor selection methods, demonstrating the merits of two-sensor platform for indoor motion monitoring and elderly care applications.
Adhesion of mammalian cells to a recombinant attachment factor, CBD/RGD, analyzed by image analysis

A luminance thresholding procedure was developed to quantify cell attachment of a variety of cell lines to CBD/RGD, a hybrid attachment factor comprising a cellulose binding domain and the fibronectin‐like RGD attachment peptide. The technique used local thresholding, median filtering, and opening to separate and count cells on each image. Cell lines exhibited three different patterns of attachment to CBD/RGD, depending on whether it was immobilized on polystyrene or cellulose acetate. Vero, COS, HFF, 3T3, 293, and U373 cells attached well to CBD/RGD immobilized on polystyrene or cellulose acetate. CHO, MRC‐5, and HEp‐2 cells attached to CBD/RGD immobilized on polystyrene, but not to CBD/RGD immobilized on cellulose acetate. BHK and L cells failed to attach to CBD/RGD immobilized on either polystyrene or cellulose acetate. The attachment of many cell lines to CBD/RGD was comparable with attachment of these cells to fibronectin. © 1995 John Wiley & Sons, Inc.

This paper presents the electrical and thermal behaviour of an advanced lithium-ion capacitor (LIC) based rechargeable energy storage systems. In the proposed study, an extended statistical analysis has been performed to evaluate the main electrical parameters such as resistance, power, capacitance, rate capabilities, variation between cells and thermal parameters. Based on the performed analysis, an electrical model has been developed for dimensioning and evaluation of various applications based on lithium-ion capacitor technology.
Type A Acute Aortic Dissection

Purpose: To understand why the false channel (FC) remains patent after surgery of type A acute aortic dissection (TAAAD). Materials and Methods: Postoperative contrast-enhanced computed tomography scans of 129 patients operated for TAAAD were analyzed, and a color-Doppler ultrasound examination (CDUS) of the supra-aortic vessels (SAVs) was performed in 12 patients. Results: The FC remained patent in 107 (82.9%) patients. The entry site was situated near the distal anastomosis in 43 (40.2%) patients and far from it in 44 (41.1%) patients. In 10 (9.35%) patients, an entry site was observed only in the SAVs. In 10 (9.35%) patients, no entry site was seen. Of the 12 patients explored with CDUS, a retrograde filling of the FC was observed in 11 patients. Conclusion: The frequent postoperative circulating aortic FC can be explained by the persistence of the primary entry tear, the presence of iatrogenic tears, and/or a retrograde filling in the SAVs.
Rodent Test of Attention and Impulsivity: The 5‐Choice Serial Reaction Time Task

The 5‐choice serial reaction time task (5‐CSRTT) is employed extensively to measure attention in rodents. The assay involves animals trained to respond to a brief, unpredictable visual stimulus presented in one of five locations. The effects of experimental manipulations on response speed and choice accuracy are measured, and each related to attentional performance. The 5‐CSRTT is also used to measure motor impulsivity. Adapted from a human task, the 5‐CSRTT can be employed with rodents or primates, highlighting its translational value. Another strength of this procedure is its adaptability to task modification. An example is the 5‐choice continuous performance task, which has both target and non‐target trial types. Overall, the 5‐CSRTT has proven to be valuable for drug discovery efforts aimed at identifying new agents for the treatment of central nervous system disorders and for further understanding the neurobiological processes of attention and impulsivity. Its flexibility offers considerable scope to the experimenter, and in this respect the task continues to evolve. © 2017 by John Wiley & Sons, Inc.
Treatment of patients with advanced colorectal carcinomas with fluorouracil alone, high-dose leucovorin plus fluorouracil, or sequential methotrexate, fluorouracil, and leucovorin: a randomized trial of the Northern California Oncology Group.

We compared the effectiveness of fluorouracil (5-FU) alone (arm A), high-dose leucovorin plus 5-FU (arm B), and sequential methotrexate, 5-FU, and leucovorin (arm C) for treatment of patients with advanced colorectal carcinomas who had not received prior chemotherapy. Arm A consisted of infusions of 5-FU at 12 mg/kg/d intravenously (IV) for 5 days followed by weekly infusions of 5-FU at 15 mg/kg; arm B consisted of leucovorin infusions at 200 mg/m2/d IV plus infusions of 5-FU at 400 mg/m2/d IV on days 1 through 5 of a 28-day cycle; arm C consisted of methotrexate at 50 mg/m2 orally every 6 hours for five doses followed by infusions of 5-FU, 500 mg/m2 IV, and leucovorin, 10 mg/m2 orally, every 6 hours for five doses every other week. A total of 265 patients were entered into the trial, of whom 249 (94%) were fully evaluable. The objective response rate (complete [CR] plus partial [PR] responses) was 17.3% on arm A, 18.8% on arm B, and 19.8% on arm C (log-rank test, P greater than .4). The median time to failure was 138 days on arm A, 166 days on arm B, and 182 days on arm C (log-rank test, P values of arm A v B = .06; arm A v arm C = .04). Median survival was 345 days on arm A, 324 days on arm B, and 356 days on arm C (log-rank test, P greater than .4). Treatment with 5-FU alone was significantly more dose intensive and more toxic than either of the experimental combinations. The rates of grade 3 or greater nonhematologic toxicity were 42.3% on arm A, 24.3% on arm B, and 14.3% on arm C. Hematologic toxicity was milder but had the same pattern. This study indicates that these regimens of high-dose leucovorin plus 5-FU and sequential methotrexate, 5-FU, and leucovorin are not more effective than is 5-FU alone for treatment of patients with colorectal carcinomas when 5-FU is administered at high-dose intensity.
La faune sauvage indicateur possible du risque de maladie émergente.

RESUME : Le mécanisme épidémiologique d'une émergence à partir de la faune sauvage peut revêtir deux modalités, soit un processus anadémique (anazootique) qui voit un réservoir sauvage auto entretenu, alimenter la population « domestique » en cas (rage vulpine), soit un processus véritablement épidémique (épizootique) qui voit un agent pathogène « sauvage » s'adapter aux populations « domestiques » (peste). La prévision de ces dangers nécessite l'étude de la faune sauvage comme facteur de risque (pour la santé de l'homme et de l'animal). L'identification précoce des épizooties des espèces de faune sauvage pourrait être améliorée par le développement d'outils génériques de dépistage (moléculaires) et de surveillance (informatiques). La prévention de ces risques passe par l'analyse spatiale de la prévalence des maladies de la faune sauvage. A cet égard, certaines espèces sauvages sont utiles à prendre en considération en priorité.
Kwaliteit van leven van patiënten in de langdurige forensische psychiatrie

Achtergrond: In de langdurige forensische psychiatrie (LFPZ) speelt kwaliteit van leven (KVL) van patienten een belangrijke rol. Doel: Een overzicht geven van de huidige kennis die er de afgelopen jaren over KVL in de LFPZ is opgedaan. Methode: De KVL wordt sinds 2007 jaarlijks onderzocht in de LFPZ, middels de speciaal voor de LFPZ ontwikkelde Forensic inpatient Quality of Life Questionnaire (FQL). Binnen dit longitudinale onderzoek hebben er inmiddels verschillende studies plaatsgevonden naar mogelijke determinanten van KVL. Resultaten: De KVL van patienten in de LFPZ leek niet zozeer samen te hangen met patientkenmerken, maar meer met de omstandigheden waarin zij verbleven en de mate waarin zij deze omstandigheden accepteerden. Daarnaast bleken de zorgverleners vaak niet goed op de hoogte van de KVL van hun patienten. Conclusie: De bevinding dat vooral omgevingskenmerken samenhangen met KVL, biedt een gunstig perspectief op het eventueel verbeteren/optimaliseren van de KVL van patienten in de LFPZ. Zo zouden zorgverleners mogelijk getraind kunnen worden in gestructureerde gespreksvoering over KVL met hun patient, met als doel om eventuele verbeterpunten aan het licht te brengen en om samen met hun patient deze punten te veranderen om de KVL van de patient te optimaliseren.
Unified description of accretion flows around black holes

We provide a unified description of thermal equilibria of black hole accretion disks, including the newly discovered advection-dominated solutions. We classify the solutions on the basis of optical depth and impotance of advection cooling. We demonstrate that only four physically distinct topological types of equilibria exist. Two of the types correspond to optically thin and optically thick equilibria, while the other two types are distinguished by whether advection is negligible or dominant. A stable Shakura-Sunyaev disk exists only for accretion rates dot-M below a certain maximum. However, there is a critical viscosity parameter alpha(sub crit), which is a function of radius, such that for alpha greater than alpha(sub crit) advection-dominated solutions exist for all dot-M. Even when alpha less than alpha(sub crit), the advection-dominated solutions are available for a wide range of dot-M except for a gap around the Eddington rate. We therefore suggest that advection-dominated flows may be more common than standard thin disks in black hole systems. For certain ranges of radii and dot-M, no stable steady state solution is possible. In these cases, we suggest that limit cycle behavior may occur, leading to variability.
