Spatial SINR Games of Base Station Placement and Mobile Association

We study the question of determining locations of base stations that may belong to the same or to competing service providers. We take into account the impact of these decisions on the behavior of intelligent mobile terminals who can connect to the base station that offers the best utility. The signal to interference and noise ratio is used as the quantity that determines the association. We first study the SINR association-game: we determine the cells corresponding to each base stations, i.e., the locations at which mobile terminals prefer to connect to a given base station than to others. We make some surprising observations: (i) displacing a base station a little in one direction may result in a displacement of the boundary of the corresponding cell to the opposite direction; (ii) A cell corresponding to a BS may be the union of disconnected sub-cells. We then study the hierarchical equilibrium in the combined BS location and mobile association problem: we determine where to locate the BSs so as to maximize the revenues obtained at the induced SINR mobile association game. We consider the cases of single frequency band and two frequency bands of operation. Finally, we also consider hierarchical equilibria in two frequency systems with successive interference cancellation

Interrogating Impunity through Counterpublic: Rethinking Habermas's Public Sphere in Paulaumi Duttagupta's Onaatah of the Earth

The present paper aims at analyzing the inevitable relationship of patriarchal impunity with counterpublic in India with reference to Onaatah of the Earth (2017) by Paulami Duttagupta. It is apparent that much of the discourse on counterpublic emphasizes on either countering the existing state agencies as mentioned by Nancy Frazer where she critiques the exclusionary practices of bourgeois public sphere labeling the process as undemocratic or advocating locational counterpublic to uplift the subalterns to establish democracy discussed by Kanika Batra. However, not much has been discussed about the exclusion of discourses critiquing impunity which forms an essential background to establish a correlation between patriarchal impunity and the counterpublic. Thus, the paper attempts to examine bourgeois public sphere mainly as a patriarchal discursive arena disseminating and strengthening the idea of impunity granted, especially in cases of sexual violence within the framework of Habermas’s public sphere. The study also focuses on how the novel Onaatah of the Earth acts as a counterpublic to undermine or neutralize the impunity by addressing issues related to gender sensitivity bringing them forth not only in discursive space but in activism too

EFFECT OF NITROGEN LEVELS ON GROWTH ATTRIBUTES, YIELD AND NUTRIENT UPTAKE OF DIFFERENT RICE (Oryza sativa L.) VARIETIES UNDER THE TRANSPLANTED CONDITION

Rice is very responsive to nitrogen fertilization under transplanted conditions; however N use efficiency and uptake by different varieties may vary. A field study was conducted during the rainy season of 2017 to assess the effect of four nitrogen levels in three rice varieties under the transplanted condition at Agricultural Research Farm, Banaras Hindu University, Varanasi, Uttar Pradesh. The experiment was carried out in a split-plot design (SPD) with three replications. The total number of treatments was twelve involving three rice varieties (V1- BPT-5204, V2- Rajendra Kasturi and V3- HUBR 2-1) in main plots and four nitrogen levels (N1- 100, N2- 120, N3- 140, and N4- 160 kg ha-1) in sub-plots. Rice variety BPT- 5204  recorded significantly higher growth parameters viz. leaf number hill-1(37.17), SPAD value (chlorophyll content 31.83), the higher number of days taken to 50 percent flowering (103 days), maturity (130.17 days), grain yield (50.73 q ha-1), biological yield (112.90 q ha-1) and harvest index (0.45) as well as NPK uptakes by grain (60.96, 13.01 & 10.95 kg ha-1) and straw (29.72, 7.15 & 101.55 kg ha-1) as compared to other varieties. However, straw yield (62.17 q ha-1) was reported higher under HUBR 2-1 as compared to the rest varieties. Among the nitrogen levels, N4-160 kg N ha-1 was recorded significantly higher above the same parameter as compared to other nitrogen levels. Hence, the application of N @ 160 kg ha-1 along with rice variety BPT- 5204 can be recommended for achieving higher rice yield, nutrient uptake, and efficiency in Eastern Uttar Pradesh

A coalitional game model for spectrum pooling in wireless data access networks

We consider a setting in which several operators offer downlink wireless data access services in a certain geographical region. Each operator deploys several base stations or access points, and registers some subscribers. In such a situation, if operators pool their infrastructure, and permit the possibility of subscribers being served by any of the cooperating operators, then there can be overall better user satisfaction, and increased operator revenue. We use coalitional game theory to investigate such resource pooling and cooperation between operators.We use utility functions to model user satisfaction, and show that the resulting coalitional game has the property that if all operators cooperate (i.e., form a grand coalition) then there is an operating point that maximizes the sum utility over the operators while providing the operators revenues such that no subset of operators has an incentive to break away from the coalition. We investigate whether such operating points can result in utility unfairness between users of the various operators. We also study other revenue sharing concepts, namely, the nucleolus and the Shapely value. Such investigations throw light on criteria for operators to accept or reject subscribers, based on the service level agreements proposed by them. We also investigate the situation in which only certain subsets of operators may be willing to cooperate

Comparison of carbetocin and oxytocin in the prevention of atonic post-partum hemorrhage following normal vaginal delivery

Background: Post-partum hemorrhage is the leading cause of maternal mortality worldwide. Use of uterotonic drugs in active management of third stage of labour has been found to be most effective in prevention of PPH.  Aims and objectives were to compare the efficacy and safety of carbitocin and oxytocin for prophylaxis of post-partum hemorrhage after singleton, term vaginal deliveries.Methods: Prospective randomized interventional study of 250 women with singleton term pregnancies undergoing vaginal delivery at MGM Women and Children’s Hospital, Kalamboli from May 2021 to May 2022. Participants randomized into 2 groups, group A and B receiving carbitocin and oxytocin respectively. Post-delivery uterine tone, vaginal bleeding, change in Hb and PCV, occurrence of adverse effects used to assess efficacy and safety of both drugs.Results: Carbetocin was statistically equal to oxytocin in preventing uterine atony and hence PPH, with similar duration of uterotonic action and lesser requirement of other uterotonic drugs. There was no incidence of adverse effects in either group.Conclusions: Since carbetocin is an effective, room temperature stable uterotonic drug with minimal side effects, it can be beneficial for use in prevention of PPH in rural settings

Research Contribution of major Centrally Funded Institution Systems of India

India is now among the major knowledge producers of the world, ranking among the top 5 countries in total research output, as per some recent reports. The institutional setup for Research & Development (R&D) in India comprises a diverse set of Institutions, including Universities, government departments, research laboratories, and private sector institutions etc. It may be noted that more than 45% share of India's Gross Expenditure on Research and Development (GERD) comes from the central government. In this context, this article attempts to explore the quantum of research contribution of centrally funded institutions and institution systems of India. The volume, proportionate share and growth patterns of research publications from the major centrally funded institutions, organised in 16 groups, is analysed. These institutions taken together account for 67.54% of Indian research output during 2001 to 2020. The research output of the centrally funded institutions in India has increased steadily since 2001 with a good value for CAGR. The paper presents noteworthy insights about scientific research production of India that may be useful to policymakers, researchers and science practitioners in India. It presents a case for increased activity by the state governments and private sector to further the cause of sustainable and inclusive research and development in the country

A review on pregabalin for the treatment of painful diabetic peripheral neuropathy

Pregabalin is an anti-epileptic drug which has been used for the treatment of diabetic peripheral neuropathy. Earlier, it was more prescribed as an adjuvant therapy for treating the partial seizures with or without secondary generalization in adults. It is an antagonist of voltage sensitive calcium ion channel on the presynaptic neuron. Pregabalin has a very good pharmacokinetic profile, possesses linear pharmacokinetics with low inter-variability of subjects. It does not show protein binding and does not interfere with the metabolism of other drugs because pregabalin undergoes very less metabolism. This factor has confirmedly shown that its benefits outweigh the risk. Different clinical trials and case reports have confirmed the fact that is reduces the pain involved in peripheral neuropathy. Though, more drugs have come like tricyclic antidepressant to manage the pain but due to their adverse effects, they are less used. This reappraisal is all about the pregabalin, its role, and where it stands among other drugs for management of pain aassociaed with diabetic peripheral neuropathy

Fundus flavimaculatus: Clinical images and review of literature

Stargardt disease (STGD) or fundus flavimaculatus is a progressive form of juvenile macular degeneration with considerableclinical and genetic heterogeneity. It may be considered a syndromal cone-rod dystrophy due to overlapping clinical features suchas loss of color vision and photophobia in some patients. Here, we report a case of fundus flavimaculatus in a 32-year-old femaleand discuss the literature pertaining to it. Clinical data including medical history, findings on physical examination and localexamination were suggestive of fundus flavimaculatus. Best-corrected visual acuity of the patient remained constant at 6/12 for1 year with the patient being on 3-month follow-up. No particular or specific treatment is available for this fundus dystrophy andfrequent follow-ups may help diagnose and manage associated choroidal neovascular membrane at the earliest. The only modalityis available in the form of low vision aids for advanced disease
