Abstract	The quantification of 3-D shape aesthetics has so far focused on specific shape features and manually defined criteria such as the curvature and the rule of thirds. In this article, we built a model of 3-D shape aesthetics directly from human aesthetics preference data and show it to be well aligned with human perception of aesthetics. To build this model, we first crowdsource a large number of human aesthetics preferences by showing shapes in pairs in an online study and then use the same to build a 3-D shape multiview-based deep neural network architecture to allow us to learn a measure of 3-D shape aesthetics. In comparison to previous approaches, we do not use any predefined notions of aesthetics to build our model. Our algorithmically computed measure of shape aesthetics is beneficial to a range of applications in graphics such as search, visualization, and scene composition.

Abstract	Visual aesthetics of 3-D shapes is a fundamental perceptual attribute. In this article, we explore the question of how different shape representations affect the aesthetic judgments of shape pairs. Specifically, we compare human responses to perceptual aesthetics judgments on 3-D shapes in pairs presented in different 3-D shape representation, such as voxels, points, wireframe, and polygon. In contrast to our own previous work [Dev et al. (2017)] that explores this question for a few shape classes, this article analyzes a larger number of shape classes. Our key finding is that human aesthetics judgments on relatively low resolution of points or voxels are comparable to polygon meshes, which implies that humans can often make their aesthetics decisions based on relatively coarse representations of the shapes. Our results have implications toward the data collection process of pairwise aesthetics data and the further use of such data in shape aesthetics and 3-D modeling problems.

Abstract	Objective: This research addresses the challenges of maintaining proper yoga postures, an issue that has been exacerbated by the COVID-19 pandemic and the subsequent shift to virtual platforms for yoga instruction. This research aims to develop a mechanism for detecting correct yoga poses and providing real-time feedback through the application of computer vision and machine learning (ML) techniques. Methods and Procedures: This study utilized computer vision-based pose estimation methods to extract features and calculate yoga pose angles. A variety of models, including extremely randomized trees, logistic regression, random forest, gradient boosting, extreme gradient boosting, and deep neural networks, were trained and tested to classify yoga poses. Our study employed the Yoga-82 dataset, consisting of many yoga pose images downloaded from the web. Results: The results of this study show that the extremely randomized trees model outperformed the other models, achieving the highest prediction accuracy of 91% on the test dataset and 92% in a fivefold cross-validation experiment. Other models like random forest, gradient boosting, extreme gradient boosting, and deep neural networks achieved accuracies of 90%, 89%, 90%, and 85%, respectively, while logistic regression underperformed, having the lowest accuracy. Conclusion: This research concludes that the extremely randomized trees model presents superior predictive power for yoga pose recognition. This suggests a valuable avenue for future exploration in this domain. Moreover, the approach has significant potential for implementation on low-powered smartphones with minimal latency, thereby enabling real-time feedback for users practicing yoga at home.

Abstract	The present study aimed to investigate the technical efficiency of agricultural growers in Mid-Himalayan areas of Himachal Pradesh using Cobb-Douglas Stochastic Frontier model. A sample of 140 adopters (involved with watershed development activities) and 140 non-adopters (outside the watershed activities) was selected using multistage random sampling technique. The study reveals that a one per cent increase in the use of quantity of each input resources such as seed, fertilizer, plant protection, farm yard manure and irrigation, on an average increased the technical efficiency by 0.414, 0.301, 0.025, 0.012, 0.194 and 0.019 per cent respectively on adopter farms, whereas in case of non-adopter farms, a one per cent increase in the use of quantity of each input resources such as seed, fertilizer, farm yard manure, labor and irrigation, on an average increased the technical efficiency by 0.263, 0.309, 0.194, 0.317, and 0.021 per cent. The mean technical efficiencies of the adopters and non-respondents respondents were found 83 and 79 per cent. Thus, there is a potential for adopters and non-adopters respondents to increase their efficiency by 17 and 21 per cent, if they use their existing farm resources efficiently. We concluded that inadequate training, exposure, knowledge gap and extension service to farmers in study area were the reasons that farmers were using their resources inefficiently.

Abstract	Objective: A common genito-urinary infection known as Balanoposthitis presents with mild symptoms like itching or severe complications such as phimosis, ulceration of glans, and foreskin. It can result in four types of sexual dysfunction including Disorder of sexual desire, Disorder of erectile dysfunction, Disorder of satisfaction/premature ejaculation, and Disorder of orgasm. Materials and methods: An observational clinic study including 50 patients diagnosed with Candidal Balanoposthitis based on KOH and clinical findings were recruited and evaluated for sexual function using a standardised questionnaire. Results: The results demonstrated that sexual dysfunction in patients with Candidal Balanoposthitis is a common entity encountered in STI clinics and should be addressed properly as any deficiency in any aspect of sexual health of a patient can lead to emotional and psychological disability impacting the overall quality of the life. The factors like advanced age, Diabetes Mellitus, and poor hygiene measures of genitalia can increase the incidence of candidal Balanoposthitis as well as sexual dysfunction. Conclusion: Candidal Balanoposthitis, a common cause of sexual dysfunction in elderly population takes a toll on emotional and psychological health and certain modifiable factors like diabetic control and hygiene can prevent recurrent fungal infections.

Abstract	Lipedema is an adipofascial disorder that almost exclusively affects women. Lipedema leads to chronic pain, swelling, and other discomforts due to the bilateral and asymmetrical expansion of subcutaneous adipose tissue. Although various distinctive morphological characteristics, such as the hyperproliferation of fat cells, fibrosis, and inflammation, have been characterized in the progression of lipedema, the mechanisms underlying these changes have not yet been fully investigated. In addition, it is challenging to reduce the excessive fat in lipedema patients using conventional weight-loss techniques, such as lifestyle (diet and exercise) changes, bariatric surgery, and pharmacological interventions. Therefore, lipedema patients also go through additional psychosocial distress in the absence of permanent treatment. Research to understand the pathology of lipedema is still in its infancy, but promising markers derived from exosome, cytokine, lipidomic, and metabolomic profiling studies suggest a condition distinct from obesity and lymphedema. Although genetics seems to be a substantial cause of lipedema, due to the small number of patients involved in such studies, the extrapolation of data at a broader scale is challenging. With the current lack of etiology-guided treatments for lipedema, the discovery of new promising biomarkers could provide potential solutions to combat this complex disease. This review aims to address the morphological phenotype of lipedema fat, as well as its unclear pathophysiology, with a primary emphasis on excessive interstitial fluid, extracellular matrix remodeling, and lymphatic and vasculature dysfunction. The potential mechanisms, genetic implications, and proposed biomarkers for lipedema are further discussed in detail. Finally, we mention the challenges related to lipedema and emphasize the prospects of technological interventions to benefit the lipedema community in the future.

Abstract	Study assesses the inequality arising from variations of economic opportunities across different agro-climatic zones of Himachal Pradesh. The poor in the state tends to diversify their income portfolio towards wages and salaries. Income from wages and salaries is most equally distributed, yet it contributes maximum (43.63%) in total inequality. The high Gini correlation of wages and salaries with total income (Rₖ=0.597), showing that households which are above in the total income stratum derive more income from wages and salaries activities, also contributed its share (43.63%) in total inequality. Wages and salaries and livestock inequalities are increasing in its effect; other factors remaining constant. One per cent increase in income from wages and salaries and livestock, increased total inequality by 0.115 and 0.140 per cent. The income from agriculture and livestock tend to significantly reduce income inequality in the state. However, agriculture is the major income source across all Zones showed a wide disparity among the share of other sources in the total income. Income of households was more unevenly distributed in the Zone-II, and Gini index for the Zone-II (Gₖ =0.231) was higher than that of the Zone-IV, Zone-III and Zone-I of the state. The result of the Theil index emphasized within group inequality was the key contributor to overall disparity across agro-climatic zones. Therefore, Policy intervention at zonal level would be imperative for correcting spatial imbalances in income distribution among agricultural households of Himachal Pradesh, and would cover the way for their comprehensive and more unbiased development.

Abstract	Alzheimer's disease (AD), a progressive neurodegenerative disorder, has emerged as the most common form of dementia in the elderly. Two major pathological hallmarks have been identified for AD: extracellular amyloid plaques and intracellular neurofibrillary tangles (NFT). Recently, dynamin-related protein 1 (Drp1) was recognized to contribute significantly towards the pathogenesis of AD. Drp1 is primarily located in the cytosol, from where it translocates to the mitochondrial outer membrane and drives the mitochondrial fission via GTP hydrolysis. Drp1 interacts with Aβ and phosphorylated tau, leading to excessive mitochondrial fragmentation, which in turn results in synaptic dysfunction, neuronal damage and cognitive decline. Several studies suggest an increase in the level of Drp1 in the post-mortem brain specimen collected from the AD patients and murine models of AD. Interestingly, heterozygous deletion of Drp1 in the transgenic murine model of AD ameliorates the mitochondrial dysfunction, improving learning and memory. The current review article discusses the possible mechanistic pathways by which Drp1 can influence the pathogenesis of AD. Besides, it will describe various inhibitors for Drp1 and their potential role as therapeutics for AD in the future.
