Real time dangerous action warning system based on graph convolution neural network

: In order to solve a series of disadvantages of slow efficiency and high cost brought by the traditional human action recognition method based on manual feature extraction, in order to prove the feasibility of using graph convolution neural network and action recognition, a real-time dangerous action alarm system based on graph convolution neural network is designed and implemented. The system includes data collection, human posture estimation, action recognition, dangerous action alarm and other functions. The feasibility of using graph convolution neural network to realize real-time dangerous action alarm system is proved by the system. Even if the graph convolution neural network does not pass the training, it can extract good features only by using the original random initialization parameters. If certain annotation information is given, its effect can be greatly improved. After the system adopts the graph convolution neural network, the action recognition can be more accurate, more efficient, faster and more reliable than the traditional method.
Design and Implementation of 45nm Operational Amplifier

— Due to its extensive use of analog computation and signal processing, the operational amplifier is the most dominant device in the field of electronics. The main aim of this paper is to design and implement a two stage complementary metal oxide-semiconductor operational amplifier using required specifications. It also aims to examine the various results for various parameters. The simulation is carried out using Tanner tool which uses 45nm technology and the two stage metal oxide semiconductor operational amplifier runs on a supply voltage. Moreover the feasibility of this circuit is heavily dependent on the process variation, which has a significant advantage over analog circuits. As a result, various simulations including AC, DC and Temperature analysis have been carried out for validation additionally, specified gain of 80dB, Phase margin and power dissipation have also been carried out.
Reviewing the case of the atypical central-engine activity in GRB 110709B

The unusual GRB 110709B triggered Swift/BAT twice, with a time difference of $\sim 11$ minutes. Its light curve presented three noticeable peaks but only two were originally identified. In this work, we describe each peak as due to a different central-engine phase: the first one is the millisecond-protomagnetar stage, the second one is the BH-formation collapse phase and the last one is the Collapsar scenario with a Blandford-Znajek engine. Additionally, we analyze and explain the afterglow phase evoking the standard fireball model. Our model can successfully describe the timescales, fluxes and spectral indices observed for GRB 110709B.

Borgaonkar HP. Pumijumnong N, Buckley BM. Taesurnrith 0 & Chutiwat S 2001. Tree ring analysis of teak (Tectona grandis) ring width chronology from Mae Na. Thailand. Palaeobotanist 50( I) : 41-45. Tree ring analysis of about 39 core samples of teak (Tectona grandis) collected from undisturbed natural forest near Mae Na, Thailand was carried out. All samples show good cross matching within the tree and between the trees. Chronology statistics indicate the usefulness of the species in dendroclimatic studies. Tree growth - climate relationship based on correlation and response function analysis revealed the important role of precipitation during the monsoon months.
Protective effect of microorganism biotransformation-produced resveratrol on the high fat diet-induced hyperlipidemia, hepatic steatosis and synaptic impairment in hamsters

Background: Resveratrol, a natural antioxidant polyphenol, has the functions of anti-inflammation, anti-cancer, liver protection and cardioprotection. Microorganism biotransformation-produced resveratrol (MBR) product shows higher purity than the natural source of resveratrol and costs less than the chemically synthesized resveratrol. The aim of the present study was to investigate the protective effects of MBR in hamsters treated with a high-fat diet (HFD). Methods: MBR was obtained by the fermentative process of piceid. Hamsters were randomly divided into four groups: HFD plus oral administration of MBR 0 (C), 5 (L), 20 (M) or 50 mg/kg (H), respectively. After six-week of treatment, hamsters were sacrificed, and tissues were collected for further analysis. Results: MBR at these three dosages did not influence the appetite or growth of the hamsters. Liver enzymes, blood glucose, total cholesterol, triglyceride, and liver weight were significantly reduced in the MBR groups than in the control group. Additionally, high-density lipoprotein-cholesterol (HDL-C) was also elevated in all MBR groups. On the other hand, serum low-density lipoprotein-cholesterol (LDL-C) was decreased in the MBR groups. Triglyceride (TG) in liver tissue and fatty liver level were lower in group H. Memory-associated proteins, phosphorylation of calmodulin-dependent protein kinase II (p-CaMK II) and synaptophysin (SYP), were increased in the brains of MBR groups. Conclusion: The high yield- and short procedure-produced MBR has the potential to protect animals fed with HFD from hyperlipidemia, hepatic steatosis, hyperglycemia, and synaptic impairment, which might be beneficial for patients with these types of diseases.

Exact and asymptotic results for intrinsic volumes of Poisson k-flat processes

The intrinsic volumes induced by a stationary Poisson k-flat process inside a compact and convex sampling window are considered. Using techniques from stochastic analysis, more precisely calculus with multiple stochastic integrals and a Wiener-Ito chaos expansion of Poisson functionals, all moments and cumulants, exact and asymptotic, are calculated in terms of a family of integral-geometric functionals. Moreover, univariate central limit theorems as well as Berry-Esseen-type inequalities are shown and a multidimensional limit theorem is concluded.
Characteristics of terahertz radiation emitted from the intrinsic Josephson junctions in high-Tc superconductor Bi2Sr2CaCu2O8+δ

Characteristic features of terahertz radiation emitted from a rectangular mesa comprised stacked intrinsic Josephson junctions in the layered high-Tc superconductor Bi2Sr2CaCu2O8+δ are reported. The emission with the total power of ∼5 μW at 0.63 THz shows a characteristic spatial distribution reflecting the rectangular shape. The stability of the emission was measured for at least 20 min. and the power fluctuation was found to be less than 4%. Furthermore, the radiation is highly polarized linearly with a ratio of 50:1. All features, including the spectral purity narrower than 4 GHz at full width at half maximum, promise a stable, coherent, and continuous terahertz source for various applications.
Long-term air pollution, cardiometabolic multimorbidity, and genetic susceptibility: a multi-state modeling study of 415,855 participants

Background: Cardiometabolic multimorbidity (CMM) with at least two cardiometabolic diseases (CMDs) including type II diabetes (T2D), ischemic heart disease (IHD), and stroke, is a global health problem with multiplicative mortality risk and deserves to be investigated as a top priority. Although air pollution is a leading modifiable environmental risk for individual CMD, its impacts on CMM progression were poorly understood. Objective: To elucidate the impact of air pollution on CMM progression, individually and in the context of genetic preposition. Design: Multi-state modeling cohort study. Setting: Data were extracted from the UK Biobank. Participants: 415,855 eligible UK Biobank adults that were free of CMDs at baseline. Measurements: Annual concentrations of particulate matter (PM) with a diameter of [≤]2.5 m (PM2.5), 2.5-10 m (PM2.5-10), and [≤]10 m (PM10), and nitrogen oxides (NOx and NO2) were estimated using Land Use Regression model. Results: During a median follow-up of 8.93 years, 33,375 participants had a first CMD (FCMD), and 3,257 subsequently developed CMM. PM2.5, PM10, NO2, and NOx levels, as well as their combined exposure were associated with increased FCMD risks and even higher risks of CMM. Particularly, per a 5-g/m3 increase in PM2.5, risks for FCMD and CMM increased by 27% (95% confidence interval: 20%-34%) and 41% (18%-68%), respectively. By FCMD types, participants with IHD had a higher risk of CMM than those with T2D or stroke. Eighty-five CMD-related genetic variants were associated with CMM trajectories in our study and associations of air pollution with FCMD and CMM risks could be aggravated progressively with increasing genetic risks. Limitations: Other major air pollutants including ozone and SO2 were not considered due to the data availability. Conclusions: Air pollution has profound adverse health impacts on the progression of CMM through multi-stage dynamics, especially for individuals with IHD and high genetic risk.
PR ] 3 1 Ju l 2 00 2 COMPARISON OF DIFFERENT GOODNESS-OFFIT TESTS

Various distribution free goodness-of-fit test procedures have been extracted from literature. We present two new binning free tests, the univariate three-region-test and the multivariate energy test. The power of the selected tests with respect to different slowly varying distortions of experimental distributions are investigated. None of the tests is optimum for all distortions. The energy test has high power in many applications and is superior to the χ2 test.
Ja n 20 05 Double dot chain as a macroscopic quantum bit

We consider an array of N quantum dot pairs interacting via Coulomb interaction between adjacent dots and hopping inside each pair. We show that at the first order in the ratio of hopping and interaction amplitudes, the array maps in an effective two level system with energy separation becoming exponentially small in the macroscopic (large N) limit. Decoherence at zero temperature is studied in the limit of weak coupling with phonons. In this case the macroscopic limit is robust with respect to decoherence. Some possible applications in quantum information processing are discussed.
Polymeric sidewall transfer lithography

This work is to demonstrate a low cost and time-conserving technique to create nano-trenches by transferring nano-scale polymeric sidewalls into substrate. The polymeric sidewall is a vertically spreading layer deposited by spin-coating a polymer solution on a vertical template. By varying processing parameters such as the solution concentration or the spin-coating speed, the dimension of the sidewall can be changed, which, after pattern transfer, also changes the nano-trench dimension. In this work, high-resolution trenches of about 15 nm have been achieved after transferring straight line sidewalls into substrate. Other than straight line sidewall patterns, this method also fabricates ring-shaped patterns including circles, squares, and concentric squares. With various shapes of sidewall patterns, this technique has a potential to implement other practical applications such as fabricating high-resolution nanoimprint molds of 15 nm.
Single-joint isometric rate of torque development is not related to counter- movement jump performance in soccer players

BACKGROUND AND OBJECTIVE: The quadriceps rate of torque development (RTD) is frequently used to evaluate explosive performance, but its functional meaning has been questioned. Thus, the aim of this study was to investigate if isometric quadriceps RTD correlates with multi-joint dynamic performance and if it has greater correlation with dynamic performance than with a single-joint isokinetic test in soccer players. METHODS: Thirty-nine male soccer players (age 21 ± 5 years, body mass 75 ± 7.5 kg, height 179 ± 5 cm) performed five maximal concentric knee extension isokinetic contractions at a velocity of 180 ◦ /s, followed by three maximal voluntary isometric contractions (MVIC) with knee angle of 60 ◦ , and five countermovement jumps (CMJ). The RTD was derived from MIVC over various time intervals (of 0.05, 0.1, 0.2, 0.3 seconds, and peak RTD) and CMJ height was calculated by flight time method. Pearson Product Moment Correlations were used to determine the relationships between variables. RESULTS: Absolute and relative isokinetic PT correlated positively with CMJ height ( p 0.05, r from �0.272 to 0.296). CONCLUSION:These results indicate that single-joint isometric RTDdoes not correlate withdynamic multi-joint performance. Thus, more specific tests in relation to contraction type, velocity and/or movement pattern should be used.
Cell‐based volume integration for boundary integral analysis

The evaluation of volume integrals that arise in boundary integral formulations for non‐homogeneous problems was considered. Using the “Galerkin vector” to represent the Green's function, the volume integral was decomposed into a boundary integral, together with a volume integral wherein the source function was everywhere zero on the boundary. This new volume integral can be evaluated using a regular grid of cells covering the domain, with all cell integrals, including partial cells at the boundary, evaluated by simple linear interpolation of vertex values. For grid vertices that lie close to the boundary, the near‐singular integrals were handled by partial analytic integration. The method employed a Galerkin approximation and was presented in terms of the three‐dimensional Poisson problem. An axisymmetric formulation was also presented, and in this setting, the solution of a nonlinear problem was considered. Copyright © 2012 John Wiley & Sons, Ltd.
Site characterization studies for the Iranian National Observatory

We report on the Iranian National Observatory (INO) ongoing site characterization studies for INO 3.4m optical telescope under development. Iran benefits from high altitude mountains and a relatively dry climate, thus offer many suitable sites for optical observations. The site selection (2001-2007) studies resulted in two promising sites in central Iran, one of which will host the 3.4m telescope. The studies between 2008 and 2010 aimed at detail characterization of the two sites. This involved measurements of a number of parameters including the wind speed and wind direction, astronomical seeing, sky brightness and microthermal variations.
Role of the calibration process in reducing model predictive error

An equation is derived through which the variance of predictive error of a calibrated model can be calculated. This equation has two terms. The first term represents the contribution to predictive error variance that results from an inability of the calibration process to capture all of the parameterization detail necessary for the making of an accurate prediction. If a model is “uncalibrated,” with parameter values being supplied solely through “outside information,” this is the only term required. The second term represents the contribution to predictive error variance arising from measurement noise. In an overdetermined system, such as that which may be obtained through “parameter lumping” (e.g., through the introduction of a spatial zonation scheme), this is the only term required. It is shown, however, that parameter lumping is a form of “implicit regularization” and that ignoring the implied first term of the predictive error variance equation can potentially lead to underestimation of predictive error variance. A model's role as a predictor of environmental behavior can be enhanced if it is calibrated in such a way as to reduce the variance of those predictions which it is required to make. It is shown that in some circumstances this can be accomplished through “overfitting” against historical field data. It can also be accomplished by giving greater weight to those measurements which carry the greatest information content with respect to a required prediction. This suggests that a departure may be necessary from the custom of using a single “calibrated model” for the making of many different predictions. Instead, model calibration may need to be repeated many times so that in each case the calibration process is optimized for the making of a specific model prediction.
Estimation of temperature elevation generated by ultrasonic irradiation in biological tissues using the thermal wave method

In most previous models, simulation of the temperature generation in tissue is based on the Pennes bio-heat transfer equation, which implies an instantaneous thermal energy deposition in the medium. Due to the long thermal relaxation time τ (20 s–30 s) in biological tissues, the actual temperature elevation during clinical treatments could be different from the value predicted by the Pennes bioheat equation. The thermal wave model of bio-heat transfer (TWMBT) defines a thermal relaxation time to describe the tissue heating from ultrasound exposure. In this paper, COMSOL Multiphysics 3.5a, a finite element method software package, is used to simulate the temperature response in tissues based on Pennes and TWMBT equations. We further discuss different factors in the bio-heat transfer model on the influence of the temperature rising and it is found that the temperature response in tissue under ultrasound exposure is a rising process with a declining rate. The thermal relaxation time inhibits the temperature elevation at the beginning of ultrasonic heating. Besides, thermal relaxation in TWMBT leads to lower temperature estimation than that based on Pennes equation during the same period of time. The blood flow carrying heat dominates most to the decline of temperature rising rate and the influence increases with temperature rising. On the contrary, heat diffusion, which can be described by thermal conductivity, has little effect on the temperature rising.
Spirometric Patterns in Patients with Sleep-Related Breathing Disorders: Some Points to Highlight

Such studies are very much encouraged for at least three reasons. First, spirometry is essential to assess and follow‐up patients with chronic pulmonary diseases or chronic conditions which respiratory repercussions (e.g., sleep‐related breathing disorders (SRBD)). [2] For example, spirometry is recommended in patients with obstructive sleep apnea syndrome (OSA) who they are smokers/ex‐smokers or they are obese with respiratory symptoms. [3]
Comprehensive analysis of the GALACTINOL SYNTHASE (GolS) gene family in citrus and the function of CsGolS6 in stress tolerance

Galactinol synthase (GolS) catalyzes the first and rate-limiting step in the synthesis of raffinose family of oligosaccharides (RFOs), which serve as storage and transport sugars, signal transducers, compatible solutes and antioxidants in higher plants. The present work aimed to assess the potential functions of citrus GolS in mechanisms of stress response and tolerance. By homology searches, eight GolS genes were found in the genomes of Citrus sinensis and C. clementina. Phylogenetic analysis showed that there is a GolS ortholog in C. clementina for each C. sinensis GolS, which have evolved differently from those of Arabidopsis thaliana. Transcriptional analysis indicated that most C. sinensis GolS (CsGolS) genes show a low-level tissue-specific and stress-inducible expression in response to drought and salt stress treatments, as well as to ‘Candidatus Liberibacter asiaticus’ infection. CsGolS6 overexpression resulted in improved tobacco tolerance to drought and salt stresses, contributing to an increased mesophyll cell expansion, photosynthesis and plant growth. Primary metabolite profiling revealed no significant changes in endogenous galactinol, but different extents of reduction of raffinose in the transgenic plants. On the other hand, a significant increase in the levels of metabolites with antioxidant properties, such as ascorbate, dehydroascorbate, alfa-tocopherol and spermidine, was observed in the transgenic plants. These results bring evidence that CsGolS6 is a potential candidate for improving stress tolerance in citrus and other plants.
Cognitive and behavioral effects of whole brain conventional or high dose rate (FLASH) proton irradiation in a neonatal Sprague Dawley rat model

Recent studies suggest that ultra-high dose rates of proton radiation (>40 Gy/s; FLASH) confer less toxicity to exposed healthy tissue and reduce cognitive decline compared with conventional radiation dose rates (~1 Gy/s), but further preclinical data are required to demonstrate this sparing effect. In this study, postnatal day 11 (P11) rats were treated with whole brain irradiation with protons at a total dose of 0, 5, or 8 Gy, comparing a conventional dose rate of 1 Gy/s vs. a FLASH dose rate of 100 Gy/s. Beginning on P64, rats were tested for locomotor activity, acoustic and tactile startle responses (ASR, TSR) with or without prepulses, novel object recognition (NOR; 4-object version), striatal dependent egocentric learning ([configuration A] Cincinnati water maze (CWM-A)), prefrontal dependent working memory (radial water maze (RWM)), hippocampal dependent spatial learning (Morris water maze (MWM)), amygdala dependent conditioned freezing, and the mirror image CWM [configuration B (CWM-B)]. All groups had deficits in the CWM-A procedure. Weight reductions, decreased center ambulation in the open-field, increased latency on day-1 of RWM, and deficits in CWM-B were observed in all irradiated groups, except the 5 Gy FLASH group. ASR and TSR were reduced in the 8 Gy FLASH group and day-2 latencies in the RWM were increased in the FLASH groups compared with controls. There were no effects on prepulse trials of ASR or TSR, NOR, MWM, or conditioned freezing. The results suggest striatal and prefrontal cortex are sensitive regions at P11 to proton irradiation, with reduced toxicity from FLASH at 5 Gy.
