Effective Capacity in Broadcast Channels with Arbitrary Inputs

We consider a broadcast scenario where one transmitter communicates with two receivers under quality-of-service constraints. The transmitter initially employs superposition coding strategies with arbitrarily distributed signals and sends data to both receivers. Regarding the channel state conditions, the receivers perform successive interference cancellation to decode their own data. We express the effective capacity region that provides the maximum allowable sustainable data arrival rate region at the transmitter buffer or buffers. Given an average transmission power limit, we provide a two-step approach to obtain the optimal power allocation policies that maximize the effective capacity region. Then, we characterize the optimal decoding regions at the receivers in the space spanned by the channel fading power values. We finally substantiate our results with numerical presentations.Comment: This paper will appear in 14th International Conference on Wired&Wireless Internet Communications (WWIC

understanding and tackling poverty and vulnerability in mountain livelihoods in the hindu kush himalaya

This chapter critically reviews the existing knowledge on livelihoods, poverty, and vulnerability in the Hindu Kush Himalaya (HKH). Development in mountain areas and the practices of people in these areas are uniquely conditioned by distinct characteristics that we term "mountain specificities". Some of these specificities—such as inaccessibility, fragility, and marginality—constrain development. Others—such as abundant biological diversity, ecological niches, and adaptation mechanisms—present development opportunities for mountain people

Children patients with COVID‐19: How can parental and peer support lessen the psychological burden of isolation

Abstract Aim To assess the effect of parental and peer support on children's self‐esteem during the isolation period in COVID‐19‐infected children is the main objective of this study. Design This is a descriptive cross‐sectional study. One hundred ninety children with a confirmed diagnosis of COVID‐19 were included. Methods A survey questionnaire to assess family and children's demographic characteristics was used for this study. A 13‐item scale to assess parental support during the isolation period and a 10‐item scale to assess peers' support during the isolation period were evaluated. Along with it, a 10‐item scale to assess self‐esteem during the isolation period was also measured. Results Home isolation was associated with higher parental and peer support scores than hospital isolation. The mean age of study participants was 13.23 ± 4.05 years; 52.6% were isolated at home versus 47.4% in hospital isolation. Phone calling and WhatsApp/messenger chat were methods of communication for 44.2% and 33.2% of patients, respectively. 6.3% of them had no method of communication. Child self‐esteem was significantly affected by both parental and peer support during isolation. The increase in pronounced negative psychological effects such as disorientation, anger, low self‐esteem and post‐traumatic distress may be caused by a lack of parental care. No patient or public contribution to this study Patients or the general public were not involved in the design, analysis or interpretation of the data in this study. The study's aim and objectives were developed based on children's self‐esteem, which was limited by questionnaire data information, so the researchers completed demographic and disease‐related questionnaires by interviewing them

Association Between Type 1 Diabetes Mellitus and Eating Disorders: A Systematic Review and Meta‐Analysis

ABSTRACT Background Previous meta‐analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. Methods A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms “T1DM,” “Eating Disorders” and “Bulimia.” Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. Results T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84–3.32, p‐value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18–6.65, p‐value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18–1.98, p‐value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM‐validated questionnaires (RR = 2.80, 95% CI = 1.91–4.12, p‐value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27–3.23, p‐value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. Conclusion Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist
