In this work, the Hamiltonian of the two body problem with varying mass was developed in the extended phase space taking into consideration the periastron effects. The short period solution was obtained through constructing a second order canonical transformation using “Hori’s” method developed by “Kamel”. The elements of the transformation as well as the inverse transformation were obtained too. The final solution of the problem was derived using “Delva-Hanslmeier” method. 展开更多

Combined bodies of rock-like material and rock are widely encountered in geotechnical engineering,such as tunnels and mines.The existing theoretical models describing the stress-strain relationship of a combined body lack a binary feature.Based on effective medium theory,this paper presents the governing equation of the“elastic modulus”for combined and single bodies under triaxial compressive tests.A binary effective medium model is then established.Based on the compressive experiment of concretegranite combined bodies,the feasibility of determining the stress threshold based on crack axial strain is discussed,and the model is verified.The model is further extended to coal-rock combined bodies of more diverse types,and the variation laws of the compressive mechanical parameters are then discussed.The results show that the fitting accuracy of the model with the experimental curves of the concretegranite combined bodies and various types of coal-rock combined bodies are over 95%.The crack axial strain method can replace the crack volumetric strain method,which clarifies the physical meanings of the model parameters.The variation laws of matrix parameters and crack parameters are discussed in depth and are expected to be more widely used in geotechnical engineering. 展开更多

Reisner proved a reverse of the Blaschke-Santal5 inequality for zonoid bodies, Bourgain and Milman showed another reverse of the Blaschke-Santal5 inequality for centered convex bodies. In this paper, two reverses of the Blaschke-Santal5 inequality for convex bodies are given by the Petty projection inequality and above two reverses. Further, using above methods, we also obtain two analogues of the Petty's conjecture for projection bodies, respectively. 展开更多

Parkinson’s disease(PD)is one of the primary vital degenerative diseases that affect the Central Nervous System among elderly patients.It affect their quality of life drastically and millions of seniors are diagnosed with PD every year worldwide.Several models have been presented earlier to detect the PD using various types of measurement data like speech,gait patterns,etc.Early identification of PD is important owing to the fact that the patient can offer important details which helps in slowing down the progress of PD.The recently-emerging Deep Learning(DL)models can leverage the past data to detect and classify PD.With this motivation,the current study develops a novel Colliding Bodies Optimization Algorithm with Optimal Kernel Extreme Learning Machine(CBO-OKELM)for diagnosis and classification of PD.The goal of the proposed CBO-OKELM technique is to identify whether PD exists or not.CBO-OKELM technique involves the design of Colliding Bodies Optimization-based Feature Selection(CBO-FS)technique for optimal subset of features.In addition,Water Strider Algorithm(WSA)with Kernel Extreme Learning Machine(KELM)model is also developed for the classification of PD.CBO algorithm is used to elect the optimal set of fea-tures whereas WSA is utilized for parameter tuning of KELM model which alto-gether helps in accomplishing the maximum PD diagnostic performance.The experimental analysis was conducted for CBO-OKELM technique against four benchmark datasets and the model portrayed better performance such as 95.68%,96.34%,92.49%,and 92.36%on Speech PD,Voice PD,Hand PD Mean-der,and Hand PD Spiral datasets respectively. 展开更多

Bacterial attachment is influenced by the cell surface, attachment media and other environmental factors. Bacterial community composition involved in biofilm formation in extremely high rainfall areas like Cherrapunjee has not been reported. The present study was undertaken to characterize bacteria involved in biofilm formation on different substrata in water bodies of Cherrapunjee, the highest rainfall receiving place on planet earth and to assess if the continuous rainfall has an effect on nature and colonization of biofilm bacteria. We developed the biofilm bacteria on stainless steel and glass surfaces immersed in water bodies of the study sites. Isolation of biofilm bacteria were performed on different culture media followed by estimation of protein and carbohydrate content of bacterial exopolysaccharides. 16S rRNA gene sequences were amplified for molecular characterization. The results showed that the biofilm bacterial diversity in water bodies of Cherrapunjee was influenced by substratum and was observed more in stainless steel than glass surface. Scanning electron microscopy images revealed that biofilm microstructure may represent a key determinant of biofilm growth and physiology of associated bacteria. The overall protein content of the extracted EPS of all the isolates were relatively higher than the carbohydrate content. Diverse bacteria proliferated on the substrata regardless of each other's presence, with more diverse bacteria colonizing the substrata on 7th day compared to 15th day of incubation. The biofilm bacteria compositions in the highest rainfall receiving habitat were not distinctly different from reports available, hence not unique from other water bodies. 展开更多

Olive (Olea europaea L.) tree is one of the most extensive and important agricultural crop in Mediterranean countries due to its beneficial health and nutritional properties and its high economic value. Currently, olive tree constitutes the sixth most important cultivated plant in the world, spreading from the Mediterranean region of origin to new production areas such as Australia, South and North America and South Africa. However, the mobilization processes of storage materials i.e. reserve proteins during seed germination, which are largely involved in essential physiological process including plant growth and development, remain poorly understood. Morphometric and immunohistochemistry analyses of protein bodies contained in olive seed storage tissues, cotyledon and endosperm, were performed by using different microscopy techniques, including light (bright-field and fluorescence) microscopy and transmission electron microscopy. Furthermore, we used legumin-like proteins (11S-type globulins) as a molecular marker to study the mobilization of reserve proteins from PBs of cotyledons at germinating seedling stages by using immunofluorescence assays. Results demonstrated that cotyledon and endosperm are characterized by distinct PBs populations containing legumin-like proteins, distinctly discriminated by the number of PBs per cell and tissue, size, immunofluorescence and histochemical staining. These features reflect differential PBs biogenesis during development and maturation processes in olive seed tissues endosperm and cotyledon, in relation to proteins (polypeptides) final composition, SSPs processing and/or packaging during seed maturation. Three different mobilization patterns of legumin-like proteins were identified for the first time in cotyledon PBs during seedling germinating process. Mature proteins composition and/or processing, cell types and enzyme composition and/or differential activation have been discussed as key features determining how proteins mobilize from PBs for further degradation in the cotyledon. 展开更多

Dementia is mainly a neurodegenerative disorder involved in several systems, including central nervous system, endocrinology/metabolism system and circulatory system. Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are the most common forms of the dementia, accounting for 60% - 80% and 10% - 20% of all cases, respectively. DLB is defined by widespread neocortical, limbic and brainstem Lewy bodies but frequently accompanied by variable levels of AD pathology. This pathological and clinical overlap makes their differential diagnosis complicated. Recent advances in the identification of disease bio-markers now make it possible to detect and distinguish their pathology in the early or preclinical stage of the diseases, even in cognitively normal individuals. In addition to the key biomarkers (amyloid β or Aβ, tau and α-synuclein), neurotrophins such as cocaine- and amphetamine-regulated transcript (CART) have also drawn attention due to their expressions and functions. This article summarizes the progress in the definition, pathology and diagnosis of dementia, with a focus on potential biochemical markers in the cere-brospinal fluid (CSF) in the differential diagnosis of the main forms of dementia. To prediction or early diagnosis of dementia, the role of specific and sensitive CSF biomarkers seems to be crucial in a routine clinical setting. The concerns and challenges in the biomarker field are also discussed. 展开更多

In his Antichrist and Nymphomaniac, Lars von Trier seems to defy norms on sex and women's desires. However he actually reproduces Christianity's perspective that women are sinful by their dispositions. According to the classical creation story, Eve falls into temptation and then, convinces Adam to commit the same crime. All Abrahamic religions but especially Christianity identifies women with the body and bodily desires, rather than the mind which comes from nonmaterial and divine substance. Accordingly, women can easily be deceived by Satan since they contain a lesser amount of mental substance compared to men. In Antichrist, Trier reiterates the story of Adam and Eve in a different context. The woman writes her dissertation on women who are burnt with the accusation of being a witch. But she realizes that her body is sinful and deserving of punishment, too. She finds her salvation when she cuts her clitoris. In Nymphomaniac, the main character gets her clitoris whipped. While she resists traditional and bourgeois morality, she defines herself as morally evil because of her unmanageable sexual desires. Thus, reputed as critical of all social structures and morality, Trier in fact simply rehashes the classical sexist and misogynist perspective. 展开更多

The objective of the study was to explore the relationship between the indicators of Alzheimer’s disease and dementia with Lewy bodies using the voxel-based specific regional analysis system for Alzheimer’s Disease (VSRAD) advance. Among 36 patients with suspected dementia, patients with Alzheimer’s disease and dementia with Lewy bodies were identified using VSRAD advance from March 1 to October 30, 2019. All patients underwent brain Magnetic Resonance Imaging (MRI). We diagnosed Alzheimer’s disease using Volume of Interest (VOI) in the Medial Temporal Lobe (MTL) atrophy ratio > 2 and dementia with Lewy bodies using both VOI in the MTL atrophy ratio ≤ 2 and gray/white matter atrophy ratio ≥ 0.2. The correlation between the indicators of Alzheimer’s disease and dementia with Lewy bodies was calculated. The number of patients classified as having Alzheimer’s disease and dementia with Lewy bodies was 25 and 11, respectively. In the Alzheimer’s disease group, the correlation coefficient between the extent of gray matter atrophy and the severity of atrophy in the dorsal brainstem gray matter was r = -0.40 (p = 0.045). In dementia with Lewy bodies group, the correlation coefficient between the extent of gray matter atrophy and the severity of atrophy in the dorsal brainstem white matter was r = -0.78 (p < 0.01). Using VSRAD advance, gray matter atrophy and dorsal brainstem grey/white matter atrophy were found to be negatively correlated in Alzheimer’s disease and dementia with Lewy bodies. 展开更多

In recent decades there has been a dramatic rise in the incidence of esophageal adenocarcinoma(EAC) in the developed world. Over approximately the same period there has also been an increase in the prevalence of obesity. Obesity, especially visceral obesity, is an important independent risk factor for the development of gastro-esophageal reflux disease, Barrett's esophagus and EAC. Although the simplest explanation is that this mediated by the mechanical effects of abdominal obesity promoting gastro-esophageal reflux, the epidemiological data suggest that the EAC-promoting effects are independent of reflux. Several, not mutually exclusive, mechanisms have been implicated, which may have different effects at various points along the refluxBarrett's-cancer pathway. These mechanisms include a reduction in the prevalence of Helicobacter pylori infection enhancing gastric acidity and possibly appetite byincreasing gastric ghrelin secretion, induction of both low-grade systemic inflammation by factors secreted by adipose tissue and the metabolic syndrome with insulin-resistance. Obesity is associated with enhanced secretion of leptin and decreased secretion of adiponectin from adipose tissue and both increased leptin and decreased adiponectin have been shown to be independent risk factors for progression to EAC. Leptin and adiponectin have a set of mutually antagonistic actions on Barrett's cells which appear to influence the progression of malignant behaviour. At present no drugs are of proven benefit to prevent obesity associated EAC. Roux-en-Y reconstruction is the preferred bariatric surgical option for weight loss in patients with reflux. Statins and aspirin may have chemopreventative effects and are indicated for their circulatory benefits. 展开更多

The Wadi 'Araba peace treaty which Jordan's King Hussein signed with Israel on October 26, 1994 became a target of criticism ever since it became known to the Jordanian public. Intense pressure was exerted on the Jordanian government to revoke the treaty even before its signature. The opposition to it reached its peak in the following year, when the tension in the holy sites in Jerusalem mounted. Given the persistence of the Arab-Israeli conflict and the fact that the Palestinian issue remained unresolved, it was clear that the King was aware of the potential danger of signing a peace accord with Israel, and that he was prepared to face criticism not only from the Arab states but also from nationalists, Islamists and Leftists all of whom disapproved of his decision. Yet the King remained undeterred and boldly carried on the discussions that culminated in the peace treaty's signature. Bearing in mind the fact the Egypt was the first country to sign a peace treaty with Israel it seemed as if there was little risk involved in the normalization process, and that the opposition to the treaty would soon subside. As it turned out, however, the pressure to abrogate it continues to mount. 展开更多
