STUDY OF THE COMPUTED TOMOGRAPHY MEASUREMENT OF DIAMETER OF ABDOMINAL AORTA IN NEPALESE
Background: The diameter of abdominal aorta (DAA) has its own importance in human body in diagnosing several abdominal aortic diseases. Its size is the diagnostic parameter for the abdominal aortic aneurysm which is the localized dilation of the abdominal aorta. Methods: The DAA of Nepalese was measured according to age and sex at three different levels, just superior to the celiac axis, at renal pedicle level and just superior to bifurcation by using Computerized Tomography (CT) scan. Also the DAA of the normal people was compared to those having hypertension, alcohol consumption and smoking habit. Study Sample: Altogether, 125 patients were included who came to Tribhuvan University Teaching Hospital (TUTH), Maharajgung, Kathmandu, Nepal for abdominal CT scan. Among them 100 are normal population and 25 are the victim of hypertension, alcohol consumption and smoking habit. Results: The findings revealed that the DAA in most of the observed patients is less than the aneurysm limit i.e. smaller than 30mm except in one male patientof age 72 years. Conclusion: It is concluded that the diameter of abdominal aorta increases with ages and is pronounced more in Nepalese male population than in female. It is also higher in patients of both sexes having hypertension and smoking habit.

Sliced Wasserstein Generative Models
In generative modeling, the Wasserstein distance (WD) has emerged as a useful
metric to measure the discrepancy between generated and real data
distributions. Unfortunately, it is challenging to approximate the WD of
high-dimensional distributions. In contrast, the sliced Wasserstein distance
(SWD) factorizes high-dimensional distributions into their multiple
one-dimensional marginal distributions and is thus easier to approximate. In
this paper, we introduce novel approximations of the primal and dual SWD.
Instead of using a large number of random projections, as it is done by
conventional SWD approximation methods, we propose to approximate SWDs with a
small number of parameterized orthogonal projections in an end-to-end deep
learning fashion. As concrete applications of our SWD approximations, we design
two types of differentiable SWD blocks to equip modern generative
frameworks---Auto-Encoders (AE) and Generative Adversarial Networks (GAN). In
the experiments, we not only show the superiority of the proposed generative
models on standard image synthesis benchmarks, but also demonstrate the
state-of-the-art performance on challenging high resolution image and video
generation in an unsupervised manner.Comment: This paper is accepted by CVPR 2019, accidentally uploaded as a new

Prevalence of Refractive Errors in Nepalese Children and Adults: A Systematic Review With Meta-Analysis
Clinical relevance: Country-specific estimates of the prevalence of refractive errors are important to formulate national eye health policies for refractive care services. Background: The purpose of this study was to systematically synthesise available literature and estimate the prevalence of refractive errors in the Nepalese population. Methods: PubMed, Scopus, and Web of Science databases were systematically searched for articles on refractive errors and presbyopia published in English language until 27 September 2022. Population and school-based quantitative, cross-sectional prevalence studies and Rapid Assessment of Avoidable Blindness survey repository data were included. The quality of the included studies was assessed using the Newcastle Ottawa scale adapted for cross-sectional studies. Data extraction was performed with consensus among the reviewers. Meta-analysis of the prevalence was performed using the Random effects model to estimate the pooled proportions. Results: A total of 38 studies with 101 701 participants were included: 18 studies in children (n = 31 596) and 20 in adults (n = 70 105). In children, the estimated pooled prevalence of overall refractive errors was 8.4% (95% CI: 4.8 to 12.9) with myopia, hypermetropia and astigmatism prevalent in 7.1% (95% CI: 3.7 to 11.4), 1.0% (95% CI: 0.7 to 1.3) and 2.2% (95% CI: 0.9 to 3.9), respectively. In adults, the prevalence of refractive errors, uncorrected refractive errors, and uncorrected presbyopia were 11.2% (95% CI: 8.0 to 14.9), 7.3% (95% CI: 5.4 to 9.5) and 78.9% (95% CI: 69.1 to 87.3), respectively. Conclusions: The pooled prevalence of refractive errors is relatively low while uncorrected refractive errors and presbyopia are high in Nepalese population suggesting a need for better access to refractive care services in the country. The paucity of quality evidence on prevalence of refractive errors, particularly in children, indicates a need for a well-designed population-based study to accurately estimate the current prevalence of refractive errors
Reterritorialization of community forestry: Scientific forest management for commercialization in Nepal.
Nepal's community forestry is an example of a decentralized, participatory and autonomous development model. However, recent community forestry practices informed by the concept of scientific forestry in resource-rich and commercially lucrative Terai regions of Nepal have reversed community forestry gains. Scientific forestry, enforced through the Department of Forest has reproduced frontier power dynamics creating reterritorialization of community forestry through commercialization. Discouraging subsistence utilization and increasing commodification of high-value timber resources have been crucial in reconfiguring forest authority and territorial control. Moreover, the Scientific Forestry Programs have informally institutionalized rent-seeking practices at the local level. A local level, power nexus has developed among forest officials, contractors and community elites that systematically undermine local participation, allocation of resources for subsistence livelihoods and local autonomy. In effect, scientific forestry is recentralizing forest authority by legitimizing territorial control and the elite accumulation of benefits
Exploring the Diversity of Mechanisms Associated With Plant Tolerance to Virus Infection
Tolerance is defined as an interaction in which viruses accumulate to some degree without causing significant loss of vigor or fitness to their hosts. Tolerance can be described as a stable equilibrium between the virus and its host, an interaction in which each partner not only accommodate trade-offs for survival but also receive some benefits (e.g., protection of the plant against super-infection by virulent viruses; virus invasion of meristem tissues allowing vertical transmission). This equilibrium, which would be associated with little selective pressure for the emergence of severe viral strains, is common in wild ecosystems and has important implications for the management of viral diseases in the field. Plant viruses are obligatory intracellular parasites that divert the host cellular machinery to complete their infection cycle. Highjacking/modification of plant factors can affect plant vigor and fitness. In addition, the toxic effects of viral proteins and the deployment of plant defense responses contribute to the induction of symptoms ranging in severity from tissue discoloration to malformation or tissue necrosis. The impact of viral infection is also influenced by the virulence of the specific virus strain (or strains for mixed infections), the host genotype and environmental conditions. Although plant resistance mechanisms that restrict virus accumulation or movement have received much attention, molecular mechanisms associated with tolerance are less well-understood. We review the experimental evidence that supports the concept that tolerance can be achieved by reaching the proper balance between plant defense responses and virus counter-defenses. We also discuss plant translation repression mechanisms, plant protein degradation or modification pathways and viral self-attenuation strategies that regulate the accumulation or activity of viral proteins to mitigate their impact on the host. Finally, we discuss current progress and future opportunities toward the application of various tolerance mechanisms in the field

According to many commentators, the deterioration of Sino–US relations in recent years heralds a “new Cold War.” The new Cold War differs from its namesake in many respects, and in this paper we focus on its novel territorial logic. Containing the USSR was the overriding objective of American foreign policy for nearly four decades, but in contrast, the USA and China are engaged in geopolitical‐economic competition to integrate territory into value chains anchored by their domestic lead firms through the financing and construction of transnational infrastructure (e.g., transportation networks and regional energy grids). We show this competition poses risks as well as opportunities for small states to articulate and realise spatial objectives. We present cases from Nepal and Laos that demonstrate that by hedging between China and the USA and its partners, their governments are able to pursue spatial objectives. In order to achieve them, however, they must implement significant reforms or state restructuring. The result is the emergence of what we term the 21st‐century infrastructure state, which seeks to mobilise foreign capital for infrastructure projects designed to enhance transnational connectivity
