Could this sphere-layered contain new laws of physics that we have yet to discover? Here we study the spatial positional relationship of each sphere-layer of the Earth's atmosphere, hoping to find a mathematical geometric formula for the atmospheric distribution of the atmosphere as the vertical height changes. The formula can unify the internal correlation of the sphere-layered of the atmosphere. You can use this geometric space to predict and to subdivide to share the Earth's atmosphere, this article uses the 2n methods to build the geometric space of the atmosphere. This geometric space corresponds to the sphere-layered of the Earth's atmosphere. It is found of the atmosphere satisfying the 2n geometric space distribution and has a vertical height the periodicity of changes. This article uses 2n geometry to establish a brief internal sphere-layered model of the earth's atmosphere and a 'periodic table' that changes with height.

Reading disability or developmental dyslexia (DD) is a neurodevelopmental disorder affecting children, and the molecular mechanisms underlying are largely underdetermined, while loci and susceptibility genes are suggested by genetic mapping in families or cohorts and by genome wide association studies (GWAS). To identify a possible genetic cause, we genotyped and performed genome wide linkage analysis employing the programs LIPED and SNP6-LINK of six multigenerational families with autosomal dominant inherited dyslexia. The linkage analyses resulted in informative haplotypes segregating with the dyslexic trait in all families and a LOD score of Z>4 at 13q12.3 and 19p13.3, and a LOD score of Z>3 at 15q23-q24.1, 18q11.21, and 21q22.3. The five mapped regions are supported by previous linkage or associations studies.

The present research was conducted to establish the appropriate packaging materials for nutrient retention and shelf stability of peeled melon seeds (Citrullus lanatus). Fresh melon seeds were peeled and stored in three packaging materials- (Hessian Brown Bag (HBB), Propylene Bag (GSB) and Transparent Polyethylene Bag (TPB) for three months. Functional properties, physiochemical properties and nutrient composition of the samples were determined at the onset and after 3 months using standard AOAC methods. There was no significant difference (p>0.05) between the fresh and samples stored for 3 months in all the functional properties. Emulsion capacity decreased after 3 months, while emulsion stability increased. All the vitamins, minerals and approximate nutrients determined (except carbohydrates) decreased as the storage period increased. The indices of fat deterioration increased with the storage period. Both the storage period and the packaging material did not affect the magnesium and zinc contents; iron, manganese, vitamin B6 and vitamin A contents decreased with storage period. Melon seeds packaged in Hessian bag retained the highest amount of nutrients and was the least susceptible to deterioration by fat rancidity.","PeriodicalId":285617,"journal":{"name":"Open Access Journal of Applied Science and Technology","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139348720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such problems are typically addressed by means of the fast Fourier transform (FFT), but there will always be data sets – typically real valued in nature – that are too large to be efficiently processed in real time with existing computing technology, so that alternative approaches are needed. The approach pursued here for the spectrum analysis problem assumes that a relatively small number of outputs are likely to contain detectable levels of signal energy with such signals being detected through the use of a sparse version of the FFT (sFFT). A flexible and scalable sFFT design has been sought for implementation with silicon-based computing technology that’s able to yield resource efficient low power solutions by maximizing the computational density through exploitation of both partitioned memory and the real valued nature of the data. A theoretical analysis shows how this may be achieved with a parameterized solution which, with a low-end field programmable gate array (FPGA) device, a 2 GHz sampling rate and a 100 MHz clock rate, is able to achieve a latency of < 1 ms for a 2 million point real-data sFFT together with low resource utilization and which compares favourably with other recently published FFT and sFFT solutions","PeriodicalId":285617,"journal":{"name":"Open Access Journal of Applied Science and Technology","volume":"135 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139349692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approaches exploit pipelined FFT and memory-based FHT architectures and aim to produce resource-efficient parallel solutions as required for use in resource and power constrained environments. The FFT-based solutions involve multi PE pipelined designs, geared to streaming (or serial) operation, that exploit the conjugate symmetric nature of the real-data DFT spectrum. The FHT based solutions, which are suitably optimized versions of the regularized FHT, are geared to batch (or block-based) operation and involve a memory-based single-PE design that exploits partitioned memory in order to achieve eight fold parallelism within the PE. After outlining the performance objectives of each approach the study highlights the key properties and relative advantages/disadvantages of each, showing how the arithmetic complexity may be traded off against the memory requirement in order to optimize the use of the available silicon resources on the target computing device and to meet the appropriate timing objectives or constraints. A number of additional design issues not addressed with recent real-data FFT research – in particular, those relating to design simplicity, regularity and scalability – are also discussed which enable a more comprehensive assessment of a solution’s capabilities.","PeriodicalId":285617,"journal":{"name":"Open Access Journal of Applied Science and Technology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139359324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
