While a number of statistics are collected during an NCAA Division I men’s college basketball game, it is potentially of interest to universities, coaches, players, and fans to which these statistics are most significant in determining wins and losses. To this end, statistics were collected from two seasons of games and analyzed using logistic and least squares regression methods. The differences between the two competing teams in four common statistics were found to be significant to determining victory: assists, free throw attempts, defensive rebounds, and turnovers. The models were then used with data from the 2011-2012 Season to verify the accuracy of the models. The point spread model was also used with 2013 March Madness game statistics.

我们的银河系形成于130多亿年前,那时,某朵在宇宙中飘荡的尘埃云在自身引力的作用下向内缩,随之产生的热量和压力将其缓慢地转变为繁多的恒星和行星整个过程大致如此。关于银河系起源的细节我们仍不甚明了,对这一古老过程的研究也举步维艰。不过,一幅银河系中心及其磁场的新图像为科学家提供了全新的视角,让他们得以细致地探究促使银河系诞生的力量。

The outbreak of COVID-19 has attracted attention from all around the *** and institutions have adopted ways to fight COVID-19, but itsprevalence is still strong. The SIR model has important reference value for thenovel coronavirus epidemic, offering both preventive measures and the ability topredict future trends. Based on an analysis of the classical epidemiological SIRmodel along with key parameters, this paper aims to analyze the patterns ofCOVID-19, to discuss potential anti-COVID-19 measures, and to explain whywe need to conduct appropriate measures against COVID-19. The use of theSIR model can play an important role in public health emergencies. Among theparameters of the SIR model, the contact ratio and the reproduction ratio arethe factors that have the potential to mitigate the consequences of ***-COVID-19 measures include wearing a mask, washing one’s hands,keeping social distance, and staying at home if possible.

The late Ediacaran Shuram-Wonoka excursion, with δ^(13)C_(carb) values as low as-12‰(PDB) in marineshelf deposits and spanning up to 10 Myr, is the deepest and most protracted δ^(13)C_(carb) negative anomaly recognised in Earth history. The excursion formed on at least four continents in low(≤32°) palaeolatitudes, and in China is associated with a major phosphogenic event. Global and intrabasinal correlation, magnetostratigraphy, isotope conglomerate tests and further geochemical data are consistent with a primary or syn-depositional origin for the excursion. Continental-margin phosphorites are generated by oceanic upwelling driven by surface winds, and δ^(13)C_(carb) negative anomalies are explicable by oceanic upwelling of 13 C-depleted deep oceanic waters, arguing that a feature common to these exceptional Ediacaran events was unprecedented perturbation of the world ocean. These events occurred during the transition from an alien Proterozoic world marked by low-palaeolatitude glaciation near sea level and strong seasonality to the familiar Phanerozoic Earth with circum-polar glaciation and temperate climate, suggesting that the Shuram-Wonoka excursion is related to this profound change in Earth's climate system. Of various hypotheses for Proterozoic low-palaeolatitude glaciation, only the high obliquity(>54°) hypothesis, which posits secular decrease in obliquity to near the present-day value(23.5°) during the Ediacaran, predicts an unparalleled revolution in the Ediacaran world ocean. The obliquity controls the sense of the world ocean's meridional overturning circulation, which today is driven by the sinking of cold, dense water at the poles and upwelling driven by zonal surface *** the decreasing obliquity passed the critical value of 54° during the Ediacaran the meridional temperature gradient reversed, with the equator becoming warmer than the poles and Hadley lowlatitude(<30°-35°) atmospheric zonal circulation reversing. This reversal of the temperat

The aim of this investigation is to define a model of an alternating current impedance response that can identify the state of health of a porous electrode due to the blocked diffusion effect. To identify and simulate different pore geometries, an analytical differential equations system was studied. Standard and low performance battery products were simulated by the model and validated with electrochemical impedance spectroscopy （EIS） experimental data. The correlation between pore structure geometries and the related battery efficiency is also addressed. This investigation may clarify the possible reasons for low performance batteries. Identifying the benchmark pore geometry, parameters may be useful for the battery producers to improve the efficiency of their products. Various recovery methods are also included in this investigation to disperse the build-up of lead sulphate crystal that limits the electrolysis process in the low performance batteries.

Introduction Parkinson’s disease(PD)is a disabling disorder that signifi-cantly affects a patient’s quality of life[1].Treatments are available,but only 10%of PD patients fully adhere to their treatment regimens[2].Non-adherence is a serious problem linked to worsening symptoms and increased motor fluc-tuations[3-5].Levodopa(LD)remains the most effective treatment for PD[6].However,a single dosing treatment is only effective in the early phase of the *** the severe phase,4-5 years after diagnosis,the therapeutic window of dopamine becomes narrow,and due to its short half-life of between 0.7 and 1.4 h dosing of LD will be required every 2 h[7-9].One way to ameliorate this issue is to co-admin-ister LD with carbidopa(CD),which can increase LD’s oral bioavailability to 40-70%[10].
