Applicability of Temperature Discrete Equation to NMRF Boundary Layer Scheme in GRAPES Model
Authors: Yan-xia ZHANG , Zi-tong CHEN , Wei-guang MENG , Dao-shen XU
Published: March 2022

By deriving the discrete equation of the parameterized equation for the New Medium-Range Forecast (NMRF) boundary layer scheme in the GRAPES model, the adjusted discrete equation for temperature is obviously different from the original equation under the background of hydrostatic equilibrium and adiabatic hypothesis. In the present research, three discrete equations for temperature in the NMRF boundary layer scheme are applied, namely the original (hereafter NMRF), the adjustment (hereafter NMRF-gocp), and the one in the YSU boundary-layer scheme (hereafter NMRF-TZ). The results show that the deviations of height, temperature, U and V wind in the boundary layer in the NMRF-gocp and NMRF-TZ experiments are smaller than those in the NMRF experiment and the deviations in the NMRF-gocp experiment are the smallest. The deviations of humidity are complex for the different forecasting lead time in the three experiments. Moreover, there are obvious diurnal variations of deviations from these variables, where the diurnal variations of deviations from height and temperature are similar and those from U and V wind are also similar. However, the diurnal variation of humidity is relatively complicated. The root means square errors of 2m temperature (T2m) and 10m speed (V10m) from the three experiments show that the error of NMRF-gocp is the smallest and that of NMRF is the biggest. There is also a diurnal variation of T2m and V10m, where T2m has double peaks and V10m has only one peak. Comparison of the discrete equations between NMRF and NMRF-gocp experiments shows that the deviation of temperature is likely to be caused by the calculation of vertical eddy diffusive coefficients of heating, which also leads to the deviations of other elements.

Tropical cyclone (TC) annual frequency forecasting is significant for disaster prevention and mitigation in Guangdong Province. Based on the NCEP-NCAR reanalysis and NOAA Extended Reconstructed global sea surface temperature (SST) V5 data in winter, the TC frequency climatic features and prediction models have been studied. During 1951-2019, 353 TCs directly affected Guangdong with an annual average of about 5.1. TCs have experienced an abrupt change from abundance to deficiency in the mid to late 1980 with a slightly decreasing trend and a normal distribution. 338 primary precursors are obtained from statistically significant correlation regions of SST, sea level pressure, 1000hPa air temperature, 850hPa specific humidity, 500hPa geopotential height and zonal wind shear in winter. Then those 338 primary factors are reduced into 19 independent predictors by principal component analysis (PCA). Furthermore, the Multiple Linear Regression (MLR), the Gaussian Process Regression (GPR) and the Long Short-term Memory Networks and Fully Connected Layers (LSTM-FC) models are constructed relying on the above 19 factors. For three different kinds of test sets from 2010 to 2019, 2011 to 2019 and 2010 to 2019, the root mean square errors (RMSEs) of MLR, GPR and LSTM-FC between prediction and observations fluctuate within the range of 1.05-2.45, 1.00-1.93 and 0.71-0.95 as well as the average absolute errors (AAEs) 0.88-1.0, 0.75-1.36 and 0.50-0.70, respectively. As for the 2010-2019 experiment, the mean deviations of the three model outputs from the observation are 0.89, 0.78 and 0.56, together with the average evaluation scores 82.22, 84.44 and 88.89, separately. The prediction skill comparisons unveil that LSTM-FC model has a better performance than MLR and GPR. In conclusion, the deep learning model of LSTM-FC may shed light on improving the accuracy of short-term climate prediction about TC frequency. The current research can provide experience on the development of deep learning in this field and help to achieve further progress of TC disaster prevention and mitigation in Guangdong Province.

Lack of an Association Between a Rs9818870 Marker at the Mras Gene Locus and Acute Coronary Syndrome in Czech Males
Authors: Hubacek Jaroslav A. , Pitha Jan , Adamkova Vera
Published: March 2022

Acute coronary syndrome (ACS) including myocardial infarction is one of the leading and preventable causes of death in industrialized countries. Conventional cardiovascular risk factors are responsible for approximately 50% of cases. Attention is therefore focused also on genetic variants that are not strongly associated with conventional risk factors. One of them is the rs9818870 marker within the MRAS gene (muscle RAS oncogen homolog-gene, OMIM 608435, 3q22.3), which was recognized as a risk factor for cardiovascular events in Western populations. We analyzed the relationship between the rs9818870 variant and the risk of ACS in the Czech population. Methods: Rs9818870 (C→T) variant was successfully analyzed by PCR-RFLP at the 1,122 control males, younger than 65 years (post- MONICA study) and 1,190 males, consecutive patients with ACS (younger than 65 years). ANOVA and chisquare were used for statistical analyses. Results: Rs9818870 polymorphism was not associated with conventional risk factors (plasma lipids, blood pressure, obesity, smoking, diabetes mellitus) in the control group. We have not detected any association between the DNA marker and ACS (controls – CC = 70.8%, CT = 26.4%, TT = 2.8% vs. patients – CC = 69.7%, CT= 28.2%, TT= 2.1%; P = 0.34). Conclusion: Rs9818870 variant within the MRAS gene region is not robust risk factor for ACS development in the Czech Slavonic males.Acute coronary syndrome (ACS) including myocardial infarction is one of the leading and preventable causes of death in industrialized countries.

A insuficiência de espaços públicos adequados a prática de exercícios físicos e lazer pode influenciar negativamente o desenvolvimento motor de crianças e jovens em idade escolar. Há evidências na literatura que crianças com o desempenho motor deficitário, principalmente no que se refere à lateralidade e a orientação espacial direita-esquerda pode contribuir negativamente para a manifestação de dificuldades de aprendizagem da leitura, da escrita e da realização de cálculos matemáticos. Diante disso, o presente estudo objetivou verificar as produções existentes na literatura brasileira sobre a lateralidade e a orientação espacial direita-esquerda e o desempenho destes aspectos motores de crianças e jovens brasileiros de 6 a 14 anos. Foi realizada uma revisão sistemática de artigos completos e publicados entre 2010 e 2020 nas bases de dados Scielo, Lilacs e Periódicos Capes. Para buscar as produções foram utilizados os descritores-chave em português: “lateralidade”, “orientação espacial”, “desempenho motor”, “desempenho psicomotor” “aprendizagem”, “desempenho escolar”, “idade escolar” e “crianças”. Ao todo foram encontradas 130 produções. Após a leitura e a aplicação dos critérios de inclusão e exclusão, 10 estudos foram incluídos para a presente pesquisa. Ao analisar as produções selecionadas, foi possível verificar uma maior predominância de estudos que utilizaram a lateralidade e orientação espacial para identificar o perfil motor de crianças com dificuldades de aprendizagem e transtornos comportamentais ou de neurodesenvolvimento, além da presença de estudos que relacionam o desempenho destes aspectos motores ao desempenho escolar. Além disso, foi possível observar um baixo desempenho da lateralidade e da orientação espacial em crianças e jovens brasileiros.

In the second part of our trilogy, we begin by examining social policies sponsored by the science community and enacted by policy-makers to curtail the dynamics of the COVID-19 pandemic. Containment /mitigation strategies such as lockdowns came at great social and economic costs and yet failed to meaningfully impact the spread and evolution of the SARS-CoV-2 virus. Evidence suggests the social fallout alone from such strategies exceeded the morbid sequelae of the pandemic itself. We then examine the logic driving the one and only strategy advanced by the science community, i.e., vaccination, to neutralize SARS-CoV-2 and induce herd immunity. Evidence overwhelmingly points in but one direction: the mRNA vaccines were an unqualified failure. They neither halted viral spread nor conferred herd immunity and, in their wake, spawned a laundry list of disabling side effects. We point to a 40-fold increase in adverse event reports compared to trivalent influenza vaccines in the years preceding the pandemic. Medical science must now confront the possibility of yet another mass casualty event which, in all likelihood, will surpass any of the pharmacologically-induced disasters of the 20th century.

EXTENDING WHITE-BOX CRYPTOGRAPHY BASED OBLIVIOUS TRANSFER PROTOCOL
Authors: Danoyan D.H.
Published: March 2022

Secure computation platforms are becoming one of the most demanded cryptographic tools utilized in diverse applications, where the performance is critical. This point makes important the optimization of every component of secure computation systems. Oblivious Transfer (OT) is a fundamental cryptographic primitive heavily used in such protocols. Most of the OT protocols used today are based on public-key cryptography, hence their efficiency suffers heavily from the number of modular exponentiation operations done. OT extensions were introduced to reduce the number of basic OT protocol execution rounds requiring public-key cryptography operations. Recently a white-box cryptography based OT protocol (WBOT) was introduced that avoids using expensive public-key operations. In this article extension protocols for WBOT are presented, that further improve the novel approach by dramatically decreasing the protocol invocation count required.

Published: March 2022

In this paper the arithmetical functions with indeterminate values of arguments are regarded. It is known that every $\lambda$-definable arithmetical function with indeterminate values of arguments is monotonic and computable. The $\lambda$-definability of every computable, monotonic, 1-ary arithmetical function with indeterminate values of arguments is proved. For computable, monotonic, $k$-ary, $k \geq 2$, arithmetical functions with indeterminate values of arguments, the so-called diagonal property is defined. It is proved that every computable, monotonic, $k$-ary, $k \geq 2$, arithmetical function with indeterminate values of arguments, which has the diagonal property, is not $\lambda$-definable. It is proved that for any $k \geq 2$; the problem of $\lambda$-definability for computable, monotonic, $k$-ary arithmetical functions with indeterminate values of arguments is algorithmic unsolvable. It is also proved that the problem of diagonal property of such functions is algorithmic unsolvable, too.

Published: March 2022

Electronic states and optical transitions of a ZnO quantum ring containing few interacting electrons in an applied magnetic field are found to be very different from those in a conventional semiconductor system, such as a GaAs ring. Strong Zeeman and Coulomb interactions of the ZnO system, exert a profound influence on the electron states and on the optical properties of the ring. In particular, our results indicate that the Aharonov– Bohm effect in a ZnO quantum ring strongly depends on the electron number.

Published: March 2022

The elastic strain distribution in one layer InAs/GaAs quantum ring superlattice is calculated using the Green function method. The dependencies of the strain tensor components on spatial coordinate in three different directions are obtained. The comparison of the obtained results with ones for a single quantum ring shows that the effect of the matrix material on the strain distribution inside the ring is more pronounced in the case of single quantum ring. The behavior of the strain tensor components in different directions is strongly different both for the single quantum ring and quantum ring superlattice due to the anisotropy of the crystal lattice.

This paper reviews water quality parameters and their health effects on humans with the objective of enlightening the public on drinking water guidelines, the focal point and protection measures. It is also intended to help evade the health catastrophe that manifests as a result of ingesting water containing substances in excess concentration of recommended limits. Sources of water are reviewed, including rain water, surface water and groundwater. The presence and level of the biological, physical and chemical constituents referred to as water parameters which determine its suitability for drinking were also reviewed. Biological parameters are microorganisms, while physico-chemical parameters include temperature, color, dissolved solids, cations, etc. Drinking water quality standards as well as the health impacts of water quality parameters were discussed. Some of the health impacts include water borne diseases, organ failures, cancer, neurological damage, etc. The paper concludes that microorganisms and chemical constituents in drinking water sources and supply can directly or indirectly impair the use of the water for human consumption. Recommendations were made including the disinfection of drinking water sources to prevent growth of disease causing organisms, hand washing to prevent infections including Covid 19 virus and laboratory assessment of water quality parameters to ascertain their conformity with drinking water standards.

Authors: Philipp Nicolas M , Crawford Derek A , Fry Andrew C
Published: March 2022

The identification of sport and position-specific key performance indicators has been of increased interest to practitioners working within high performance sport settings. The aim of this study was to create statistical models, across a spectrum of position groups, that explain the largest amount of variance in on-field performance over four collegiate American football seasons. A total of four position groups were analyzed, including Wide Receiver/Tight End (n = 29), Running Backs (n = 8), Linebacker/Defensive Line (n =41), Defensive Backs (n = 28). Different tests of physical performance (back squat, bench press, hang clean, 40-yard dash, pro-agility, L-drill, vertical jump, and broad jump) were set as the independent variables, while a Total Score of On-Field Performance, consisting of position-specific game statistics was set as the dependent variable. Linear mixed models, using backwards model selection were used to identify models that best fit the position-specific data. Results revealed that models consisted of at least three different physical performance test, were position-specific, and explained the variance in on-field performance to different degrees. Significant correlations were found between physical performance models and on-field performance.

Understanding the Role of Leverage in the Outcome of A Nuclear Weapons Program
Authors: Marneni Pranav , Leiter Samuel
Published: March 2022

Why were some countries able to succeed in acquiring nuclear weapons while others didn’t when facing international pressure to stop the development of their nuclear program? I hypothesized that the level of leverage placed over the country trying to acquire nuclear weapons by its main ally and adversary is a key variable affecting the outcome of that country’s nuclear program. To test my hypothesis, I first described the different categories of leverage and I then compared the nuclear programs of North Korea and Taiwan using existing historical research and case studies. I compared the two countries to see if the categories of leverage were in fact different for the two countries. The two countries were chosen since they had different results (Taiwan failed, while the DPRK succeeded) and both had an ally and adversary that had some leverage over it. If leverage was different for the two countries it would be highly likely that leverage had a role in causing the different outcome, thus supporting my hypothesis.  If leverage was the same for the two countries, it would mean that leverage was not a factor causing the different outcome and my hypothesis would be incorrect. After comparing the nuclear programs of the two countries it was found that leverage was in fact different for the two countries, thus supporting my hypothesis.

Authors: Doherty Karen , Ryan H. Dennis , Bloniarz David
Published: March 2022

Public trees along streets and roads are often jointly managed by municipalities and electric companies. This research obtained information about community forestry programs and assessed the level of cooperation between the two management entities. The study queried electric utility staff arborists and municipal tree wardens, the arboricultural professionals in Massachusetts who are directly responsible for the planting, maintenance, and removal of street trees in urban and community forests. Results showed that the majority of communities still lack street tree inventories and management plans. Major advances in utility arboriculture have resulted in the need for trained and qualified arboricultural professionals to implement the new practices and techniques. Municipal arboriculture professionals give high ratings to the cooperation between communities and electric utilities when the private companies employ trained arborists on staff.
Tree Crown Stabilization with the Doublebelt System Osnabrück
Authors: Stobbe Horst , Dujesiefken Dirk , Schröder Klaus
Published: March 2022

Breaking-off of crown parts and large branches is a common type of tree failure and can result in substantial damage to objects and persons. The trees are often irreversibly damaged as well. Reasons for this type of failure are usually included bark in forks and decay or cracks in branches. As an alternative to topping or felling hazard trees, a tree crown stabilization system was developed for the protection of crowns endangered by possible failure. The System Osnabriick consists of at least two double belts, each strapped around the stem or branch and connected by wire cables. Wood-biological investigations on beech trees with six-year-old double-belt systems showed that neither discoloration nor fungal attack occurred in the wood and bark under the belts. The cambium beneath the belts apparently was not impaired either. The double-belt system makes it possible to maintain old trees with severe defects in urban areas by safeguarding their natural crown architecture as well as providing maximum safety to the public.
