Outage and Rate Evaluation of Drone based Decode and Forward Cooperation for Hybrid Fading Channels

In this paper, we consider a drone as a relay in Cooperative Communication (CC) to improve the network performance in an upcoming wireless network. Drone Assisted CC (DACC) is more useful when the central coordinator (base station) gets disrupted. In such a scenario, the drone works as an aerial relay and provides CC diversity to the end-users. In this article, a Decode-and-Forward (DF) protocol is used as a relaying scheme at the drone, and the Maximal Ratio Combining (MRC) scheme is used at the end-users for combining the direct and relayed signal. Here, we assume Nakagami faded channel among Airto- Ground (A2G) links and Rayleigh faded distribution between Ground-to-Ground (G2G) links. The performance of DA-CC is evaluated in a hybrid channel environment and compared based on drone height, rate, horizontal distance, and transmitted power with the existing Rayleigh and Nakagami faded distributions. The analytical expression of outage probability and the rate have been derived for analysis purposes, and Monte-Carlo simulations are used to verify the analytical results. This work can have security and surveillance applications to improve the network performance in the absence of a central base station

SINGLE COMPLETE MAXILLARY DENTURE WITH METAL DENTURE BASE - A CASE REPORT.

Treatment involving the use of a single complete denture offers various challenges to the clinician and requires careful evaluation and planning. The conditions leading to the recommendation of such a treatment can be quite varied and often compromise the success unless the opposing arch is optimally treated. Although heat cure denture base resins are the most commonly used denture base material, they are commonly found to fracture when a single complete denture is opposed to the natural dentition. In such cases, the use of a metal denture base offers many advantages as an alternative treatment option. This case report describes step by step fabrication of a single complete denture with metal denture base

Sectoral portfolio optimization by judicious selection of financial ratios via PCA

Embedding value investment in portfolio optimization models has always been a challenge. In this paper, we attempt to incorporate it by first employing principal component analysis (PCA) sector wise to filter out dominant financial ratios from each sector and thereafter, use the portfolio optimization model incorporating second order stochastic dominance (SSD) criteria to derive the final optimal investment. We consider a total of 11 well known financial ratios corresponding to each sector representing four categories of ratios, namely liquidity, solvency, profitability, and valuation. PCA is then applied sector wise over a period of 10 years from April 2004 to March 2014 to extract dominant ratios from each sector in two ways, one from the component solution and other from each category on the basis of their communalities. The two step Sectoral Portfolio Optimization (SPO) model integrating the SSD criteria in constraints is then utilized to build an optimal portfolio. The strategy formed using the former extracted ratios is termed as PCA-SPO(A) and the latter one as PCA-SPO(B). The results obtained from the proposed strategies are compared with the SPO model and two nominal SSD models, with and without financial ratios for computational study. Empirical performance of proposed strategies is assessed over the period of 6 years from April 2014 to March 2020 using a rolling window scheme with varying out-of-sample time line of 3, 6, 9, 12 and 24 months for S&P BSE 500 market. We observe that the proposed strategy PCA-SPO(B) outperforms all other models in terms of downside deviation, CVaR, VaR, Sortino ratio, Rachev ratio, and STARR ratios over almost all out-of-sample periods. This highlights the importance of value investment where ratios are carefully selected and embedded quantitatively in portfolio selection process.Comment: 26 pages, 12 table

Partial HELLP syndrome: case report

HELLP syndrome is a complication in pregnancy clustered by haemolysis, elevated liver enzymes, and a low platelet count. It is seen as a serious complication of preeclampsia and eclampsia. Serious manifestations like haemorrhage, infarction, rupture and other hepatic manifestations are usually associated with it. In this case study, 29 years old primigravida is a booked case admitted in ward at 39 weeks 1 day with decreased fetal movement for 2 days. No history of pain abdomen, bleeding per vaginum, discharge per vaginum. Her blood pressure records at the time of admission was 110/72 mmHg and she was normotensive throughout pregnancy. Urine routine examination was negative for urinary protein. However, blood tests showed platelet count of 66,1000/cumm, with ALT of 174 U/L and AST of 123 U/L on peripheral blood film. RBC were predominantly normocytic, normochromic with few macrocytes. WBC has normal morphology. Platelets were reduced on smear. Giant platelets were seen. Ursodeoxycholic acid 300 mg 12 hourly were given to the patient and 3 doses of vitamin K I/M 24 hourly. She was delivered by cesarean section which was performed due to failure of progression of labor with a deflexed head. There was presence of retroplacental clot of 4×3 cm indicating placental abruption, a complication of HELLP syndrome. From this we conclude that we should be careful in suspecting complications of full blown diseases even when the patients are asymptomatic but have atypical laboratory findings

BLUE GREEN DEPLOYMENT STRATEGY FOR APPLICATIONS USING KAFKA

BLUE GREEN DEPLOYMENT STRATEGY FOR APPLICATIONS USING KAFKA Disclosed herein is a blue-green deployment strategy for consumer applications using the Kafka system. The present disclosure proposes setting producer and consumer configurations in a way that green application consumers are able to consume messages from Kafka topic, hence enabling application teams to test their changes in a green environment. To achieve this, the present disclosure provides a rebalancing of partitions technique where the number of partitions are configured either twice the number of consumers or greater than twice the number of consumers so that all consumers in a consumer group are active and are able to consume data from Kafka topic

Social Media Use by Residents and Faculty in Otolaryngology Training Programs.

OBJECTIVES: Despite the growth of social media in healthcare, the appropriateness of online friendships between otolaryngological residents and attendings is poorly defined in the current literature. This issue is of growing importance, particularly as residency programs increasingly utilize social media as a means of connecting with and evaluating applicants due to limited in-person experiences during the COVID-19 pandemic. Our objective was to better understand the prevalence of and concerns surrounding social media use between residents and faculty. METHODS: This study sent out 2 surveys in 2017 to all United States Otolaryngology residency program directors to disperse to their residents and attendings, respectively. RESULTS: We received a response from 72 residents and 98 attendings. Our findings show that social media is commonly used by both residents and attendings, and most residents have at least 1 online friendship with an attending. Resident and attending opinions diverge on topics such as appropriateness of use, privacy settings, and professionalism. CONCLUSIONS: We call on residency programs to delineate a transparent social media policy so applicant expectations on social media are clear

Last Mile Delivery and Route Planning for Freight

This report analyzes anticipated list mile challenges in Indiana by using a scenario-based approach to develop forecasts of GDP growth and thus freight growth across industry clusters in Indiana counties; potential congestion implied by this growth; and a proactive plan to add capacity to alleviate the congestion. We use a quantitative approach to aggregate ramp level flows, industry cluster locations, county layout, and economic activity to develop our recommendations. We develop forecasts through the year 2050 based on long-term planning approaches used by other states (California, Ohio, and Utah). We use data from global databases that consider different possible geo-political scenarios and regulatory choices to scale it down to county-level impact. At the same time, we track industry cluster locations within each county, ramps from interstates, and distances to travel within the counties to reach freight destinations. The result is a report that combines macro trends with micro detail to develop potential capacity bottlenecks

Clinical outcomes and response to treatment of patients receiving topical treatments for pyoderma gangrenosum: a prospective cohort study

Background: pyoderma gangrenosum (PG) is an uncommon dermatosis with a limited evidence base for treatment. Objective: to estimate the effectiveness of topical therapies in the treatment of PG. Methods: prospective cohort study of UK secondary care patients with a clinical diagnosis of PG suitable for topical treatment (recruited July 2009 to June 2012). Participants received topical therapy following normal clinical practice (mainly Class I-III topical corticosteroids, tacrolimus 0.03% or 0.1%). Primary outcome: speed of healing at 6 weeks. Secondary outcomes: proportion healed by 6 months; time to healing; global assessment; inflammation; pain; quality-of-life; treatment failure and recurrence. Results: Sixty-six patients (22 to 85 years) were enrolled. Clobetasol propionate 0.05% was the most commonly prescribed therapy. Overall, 28/66 (43.8%) of ulcers healed by 6 months. Median time-to-healing was 145 days (95% CI: 96 days, ∞). Initial ulcer size was a significant predictor of time-to-healing (hazard ratio 0.94 (0.88;80 1.00); p = 0.043). Four patients (15%) had a recurrence. Limitations: No randomised comparator Conclusion: Topical therapy is potentially an effective first-line treatment for PG that avoids possible side effects associated with systemic therapy. It remains unclear whether more severe disease will respond adequately to topical therapy alone

Are US Multinationals Making Rational Offshoring Decisions? A Gravity Model Approach

The development of ICT technology and infrastructure has intensified the process of globalisation in developing countries. Many developing countries provide attractive opportunities for multinationals (MNCs) in terms of cost advantages, economies of scale and multi-plant economies. Developing countries not only provide large talent pools of young workers at lower costs but they provide opportunities in terms of growing product markets. Given the extensive financial resources and technical know-how of MNCs and other positive effects on the host economy like employment and productivity growth, many developing countries compete to have these firms locate to them by offering a favourable business environment, opening up their economies to foreign investment and setting low corporate tax rates.
