Abstract
In this paper, we design constant modulus waveforms for dual-function radar-communication (DFRC) systems based on a multi-input multi-output (MIMO) configuration of sensors for a far-field scenario. At first, we formulate a non-convex optimization problem subject to waveform synthesis for minimizing the interference power while maintaining a constant modulus constraint. Next, we solve this non-convex problem, iteratively, using the alternating direction method of multipliers (ADMM) algorithm. Importantly, the designed waveforms approximate a desired beampattern in terms of a high-gain radar beam and a slightly high gain communication beam while maintaining a desired low sidelobe level. The designed waveforms ensure an improved detection probability and an improved bit error rate (BER) for radar and communications parts, respectively. Finally, we demonstrate the effectiveness of the proposed method through simulation results.

Abstract
In this paper, we present a hybrid frequency shift keying and frequency division multiplexing (i.e., FSK-FDM) approach for information embedding in dual-function radar and communication (DFRC) design to achieve an improved communication data rate. Since most of the existing works focus on merely two-bit transmission in each pulse repetition interval (PRI) using different amplitude modulation (AM)- and phased modulation (PM)-based techniques, this paper proposes a new technique that doubles the data rate by using a hybrid FSK-FDM technique. Note that the AM-based techniques are used when the communication receiver resides in the side lobe region of the radar. In contrast, the PM-based techniques perform better if the communication receiver is in the main lobe region. However, the proposed design facilitates the delivery of information bits to the communication receivers with an improved bit rate (BR) and bit error rate (BER) regardless of their locations in the radar's main lobe or side lobe regions. That is, the proposed scheme enables information encoding according to the transmitted waveforms and frequencies using FSK modulation. Next, the modulated symbols are added together to achieve a double data rate using the FDM technique. Finally, each transmitted composite symbol contains multiple FSK-modulated symbols, resulting in an increased data rate for the communication receiver. Numerous simulation results are presented to validate the effectiveness of the proposed technique.

Abstract
INTRODUCTION AND OBJECTIVES Using the assessment of satisfaction of patients of labour room services, the caregiver or policymakers can identify the gaps in the implemented programmes and health policies. This study was aimed to design a valid and reliable satisfaction questionnaire that will help in identifying the aspects of gaps that need improvement. METHODS A facility and community-based observational cross-sectional study was conducted in the district of western Uttar Pradesh (India) between January 2019 and August 2020. Validation of the structured questionnaire with 34 dichotomous questions categorized under five subscales was performed by evaluating its validity and reliability. A total of 380 beneficiaries were selected from 48 government health facilities. RESULTS The calculated Content validity index was calculated to be 9.5 which was adequate as per the guidelines. The reliability analysis of the questionnaire showed that the internal consistency was high with an overall Cronbach's alpha of 0.710. The variation in Cronbach's alpha on the elimination of any question from the questionnaire ranged from 0.676 to 0.767. The mean patient satisfaction score in the total surveyed population was 24.39±4.684 (total score=34) and there was a greater variation in the satisfaction score of infrastructure when compared with other subscales. CONCLUSION The findings from this study support the reliability and validity of the patient satisfaction questionnaire as it is capable of evaluating the satisfaction in terms of delivery services provided in labour rooms as a whole.

Abstract
The abradable coatings had significantly enhanced turbomachinery performance by acting as a sacrificial seal between rotating blades and stationary casing. Further improvement in seal design to meet the higher energy demand and increase the service time has been the key challenge to solve in the gas turbine industry. Honeycomb seals have become the industry standard clearance seal technique due to their unique design and high structural strength with minimum weight. The present study proposes a concept to form a thermal shock resistance structure to achieve higher temperature capability and improve the reliability of high-temperature abradable seal structures for a hot gas path of turbines. A cavity layer of honeycomb seal structure made of SS 321 alloy was coated with advanced high-temperature ZrO2 + 7.5%Y2O3 + 4% polyester seal material using TriplexPro-210 plasma spray system. The integrity of a seal structure was assessed by a cross-sectional analysis and evaluation of the coating microstructure. Additionally, the micro-hardness test was performed to estimate coating fracture toughness, and finite element analysis was used to assess its thermo-mechanical performance. The concept proposed in this study should be further validated to develop the most capable innovative technology for advanced gas turbine abradable seal structures.

Abstract
Abstract
INTRODUCTION
Molecular classification of medulloblastomas(MB) is prognostically and therapeutically relevant and helps in better risk-stratification. Translation of this subgrouping to routine practice still remains a challenge. The most pathologist-accessible techniques for molecular subgrouping include immunohistochemistry(IHC), fluorescent in-situ hybridization(FISH) and Nanostring assay. Objectives:(1)Molecular subgrouping of MBs by IHC and FISH, and Nanostring Assay (2)To compare their efficacy against sequencing and DNA methylation, and cost for applicability in resource-constrained centers
METHODS
Ninety-five cases of MB with adequate tissue were included. Molecular subgrouping was performed by IHC for β-catenin, GAB1, YAP1, and p53; FISH for MYC amplification, and sequencing for CTNNB1, and by Nanostring Assay on the same set of MBs. Further, a subset of cases were subjected to 850k DNA methylation array.
RESULTS
IHC+FISH classified MBs into 15.8% WNT, 16.8% SHH, and 67.4% non-WNT/non-SHH subgroups; with MYC amplification identified in 20.3% cases of non-WNT/non-SHH. A single showed diffuse strong p53 positivity among the SHH subgroup. Nanostring successfully classified 91.5% MBs into 25.3% WNT, 17.2% SHH, 23% Group3 and 34.5% Group4. However, Nanostring assay failure was seen in eight cases, all of which were >8-years-old formalin-fixed paraffin-embedded tissue blocks. Concordant subgroup assignment was noted in 88.5% cases, while subgroup switching was seen in 11.5% cases. Both methods showed prognostic correlation. Among the 5 discrepant cases, which switched to WNT subgroup by Nanostring, only 2 were found to have CTNNB1 mutation. Methylation profiling performed on discordant cases revealed 1 out of 4 extra WNT identified by Nanostring to be WNT, others aligned with IHC subgroups; extra SHH by Nanostring turned out to be SHH by methylation.
CONCLUSIONS
Both IHC supplemented by FISH and Nanostring are robust methods for molecular subgrouping, albeit with few disadvantages. IHC cannot differentiate between Groups 3 and 4, while Nanostring cannot classify older-archived tumors, and is not available at most centres. WNT subgroup with the best prognosis is best detected by IHC or IHC followed by sequencing for confirmation. Nanostring Assay is better suitable to separate Group 3, the worst prognostic group from Group 4. Thus, both the methods complement each other and can be used in concert for high confidence allotment of molecular subgroups in clinical practice. The cost of IHC plus Nanostring will almost be the same as IHC plus FISH. We recommend a cost-efficient algorithmic approach using histopathological subtype and IHC as the first step followed by Nanostring or FISH, wherever suitable.

Abstract
With this Feature Article we review, for the first time, the development of DNA-host conjugates-a nascent yet rapidly growing research focus within the ambit of DNA supramolecular chemistry. Synthetic hosts (such as cyclodextrins, cucurbiturils, and calixarenes) are well-suited to be partnered with DNA, since DNA assembly and host-guest binding both thrive in aqueous media, are largely orthogonal, and exhibit controllable and input-responsive properties. The covalent braiding of these two supramolecular synthons thus leads to advanced self-assemblies and nanostructures with exciting function that range from drug delivery agents to input-triggered switches. The latter class of DNA-host conjugates have been demonstrated to precisely control protein activity, and have also been used as modulable catalysts and versatile biosensors.

Abstract
Dietary deficiency of trace elements, minerals and vitamins has been associated with severe malnutrition among young children. Although levels of severe malnutrition among children are high in developing countries, data on dietary intake of trace elements, minerals, vitamins and other nutrients by severely malnourished (SMN) children are limited. The present prospective study was conducted for a period of 12 months in order to assess the intake of trace elements, minerals, vitamins and other nutrients by SMN children and its possible interrelationship with their nutritional status. The nutritional status of 1643 children in the age group of 6 months to < 6 years, registered at 50 Anganwadi centres at district Alwar and Bharatpur in Rajasthan in India, was assessed using weight-for-age criteria. A total of 150 children were identified as severely malnourished. Mothers of 130 of the children consented to their children's participation in the study. At the end of 12 months, full data was available for 60 of the 130 SMN children. The nutritional status and intake of trace elements, minerals, vitamins and other nutrients of the 60 SMN children were analysed at monthly follow-up visits. Results revealed that there was an increase in the intake of trace elements, minerals and other nutrients during the follow-up period as compared to the baseline survey. However, in all of the follow-up visits, an overall deficient intake of all of the trace elements, minerals, vitamins and other nutrients was observed in the SMN children except for protein, calcium and magnesium. Out of 60 children, 35 moved to higher nutritional grades. It was found that the intake of trace elements, minerals, vitamin and macro-nutrients was higher among children whose nutritional status improved as compared with the group that remained in the severe malnutrition category. The present study highlights that the existence of multiple trace element and vitamin deficiencies in the diets of SMN children could play a role in the severe malnutrition of these children.

Abstract
INTRODUCTION Incidence of sudden cardiac death (SCD) has been steadily increasing all over the world. While knowing the cause of SCD is one of the favorites of the physicians involved with these cases, it is very difficult and challenging task for the forensic physician. The present report is a prospective study regarding cause of SCDs on autopsy examination in four-year period, Bangalore, India. METHODS The present prospective study is based on autopsy observations, carried out for four-year period from 2008 to 2011, and analyzed for cause of SCDs. The cases were chosen as per the definition of sudden death and autopsied. The material was divided into natural and unnatural groups. Finally, on histopathology, gross examination, hospital details, circumstantial, and police reports the cause of death was inferred. RESULTS A total of 2449 autopsy was conducted of which 204 cases were due to SCD. The highest SCDs were reported in 50-60 years age group (62.24%; n-127), followed closely by the age group 60-69 (28.43%; n-58). Male to female ratio was around 10:1. The maximum number of deaths (n=78) was within few hours (6 hours) after the onset of signs and symptoms. In 24 (11.8%) cases major narrowing was noted in both the main coronaries, in 87 (42.6%) cases in the left anterior descending coronary artery (LAD), and in 18 (51.5%) cases in the right coronary artery (RCA). The major cardiac pathology resulting in sudden death was coronary artery disease (n-116; 56.86%) and myocardial infarction (n-104; 50.9%). most of the SCDs occurred in the place of residence (n-80; 39.2%) followed closely by death in hospital (n-49; 24.01%). CONCLUSION Coronary occlusion was the major contributory cause of sudden death with cardiac origin and the highest number of deaths were reported in the age 50-59 years with male to female ratio of 10:1.

Abstract
OBJECTIVE Advanced Glycation Endproducts (AGEs), implicated as one of the major causes of diabetic complications, either directly or via receptor mediated actions, trigger downstream events in the conduit vessels, microvascular bed as well as myocardium leading to microvascular and cardiac dysfunction. The aim of this study was to characterise the activity profile of TRC4149, a novel AGE breaker compound, to determine its ability to reduce the burden of AGEs in vitro and in vivo and to evaluate whether the reduced AGE burden could translate into improvement in hemodynamic function in a model of Streptozotocin induced diabetic Spontaneously Hypertensive Rats (SHR). METHOD AGEs were prepared in vitro by incubating BSA and lysozyme with glucose or ribose while AGE-LDL was generated by copper catalyzed LDL oxidation. TRC4149 was evaluated using in vitro assays to determine its capacity to reduce the burden of AGEs and to test its antioxidant activity. To study the effect of TRC4149 on hemodynamic function, diabetic SHR implanted with telemetry transmitter were treated with TRC4149 (20 mg/kg i.p., b.i.d.) or vehicle for 14 weeks. Losartan was administered once per week and blood pressure was monitored telemetrically throughout the treatment period. Cardiac indices of systolic and diastolic function were assessed terminally using MacLab system. AGE load in aorta was determined immunohistochemically and VCAM expression was quantitated by real time PCR analysis. RESULTS TRC4149 was able to break preformed AGEs as well as reduce further AGE accumulation in vitro in a dose dependent manner. It also demonstrated a potent free radical scavenging activity. In diabetic SHR, treatment with TRC4149 retarded the decline in response to losartan over the study period, and also improved cardiac function as evidenced by an improved dP/dtmax/min, left ventricular systolic pressure and decreased left ventricular diastolic pressure as compared to untreated group. AGE load as well as VCAM expression in aorta was also reduced upon treatment. CONCLUSIONS TRC4149, a novel AGE-breaker compound, by virtue of reducing AGE load preserved endothelial and cardiac function in diabetic SHR, a model that recapitulates the microvascular and cardiac dysfunction associated with hypertension along with long-term diabetes.

Abstract
BACKGROUND The incidence of the cancers of the oral cavity, pharynx, esophagus and larynx in different population groups of India is amongst the highest reported in Asian countries. There is evidence that high dietary carotenoids and vitamin C may possibly decrease the risk of laryngeal cancer. Limited data is available from India on the association between these micronutrients and the risk of laryngeal cancer. AIMS To assess the levels of vitamin A, vitamin C and zinc in laryngeal cancer patients and healthy controls. SETTING AND DESIGN A hospital based case- control study. MATERIAL AND METHODS One hundred and fifty five laryngeal cancer patients and a control group of 155 healthy individuals constituted the study population. Individuals in the control group were individually matched with the patients for their age +/- 2 years, sex and place of residence. Venous blood was drawn from the cases and controls and estimations of vitamin A, zinc and vitamin C was done utilizing the standard procedures. STATISTICAL ANALYSIS USED Paired 't' test to compare the mean serum levels of vitamin A and zinc and plasma vitamin C between laryngeal cancer patients and controls. Univariate logistic regression analysis to calculate the odds ratios and the confidence intervals. RESULTS The mean serum vitamin A, zinc and plasma vitamin C levels were significantly lower in laryngeal cancer patients as compared to the controls. CONCLUSIONS The findings of the present study indicated a strong association of these micronutrients with laryngeal cancer in the Indian population.

Abstract
BACKGROUND AND PURPOSE "Stress" hyperglycemia may be associated with increased mortality and poor recovery in diabetic and nondiabetic patients after stroke. A systematic review and meta-analysis of the literature relating acute poststroke glucose levels to the subsequent course were done to summarize and quantify this relationship. METHODS A comprehensive literature search was done for cohort studies reporting mortality and/or functional recovery after stroke in relation to admission glucose level. Relative risks in hyperglycemic compared with normoglycemic patients with and without diabetes were calculated and meta-analyzed when possible. RESULTS Thirty-two studies were identified; relative risks for prespecified outcomes were reported or could be calculated in 26 studies. After stroke of either subtype (ischemic or hemorrhagic), the unadjusted relative risk of in-hospital or 30-day mortality associated with admission glucose level >6 to 8 mmol/L (108 to 144 mg/dL) was 3.07 (95% CI, 2.50 to 3.79) in nondiabetic patients and 1.30 (95% CI, 0.49 to 3.43) in diabetic patients. After ischemic stroke, admission glucose level >6.1 to 7.0 mmol/L (110 to 126 mg/dL) was associated with increased risk of in-hospital or 30-day mortality in nondiabetic patients only (relative risk=3.28; 95% CI, 2.32 to 4.64). After hemorrhagic stroke, admission hyperglycemia was not associated with higher mortality in either diabetic or nondiabetic patients. Nondiabetic stroke survivors whose admission glucose level was >6.7 to 8 mmol/L (121 to 144 mg/dL) also had a greater risk of poor functional recovery (relative risk=1.41; 95% CI, 1.16 to 1.73). CONCLUSIONS Acute hyperglycemia predicts increased risk of in-hospital mortality after ischemic stroke in nondiabetic patients and increased risk of poor functional recovery in nondiabetic stroke survivors.

Abstract
Iodine deficiency is an important public health problem in Himachal Pradesh. District Kangra is a known iodine deficiency endemic area. A survey conducted in 1956 reported a goitre prevalence of 55 per cent in the district. A more recent pilot study (1994) in four blocks of the district reported the total goitre rate (TGR) as 7 per cent. A continued prevalence of goitre in more than 5 per cent of school-aged children was found in pilot study, in spite of the distribution of iodised salt. The present study was conducted to assess the prevalence of iodine deficiency disorders (IDD) and to estimate the iodine content of salt consumed by the population in district Kangra. The '30 cluster' sampling methodology and indicators for assessment of IDD, as recommended by the joint WHO/UNICEF/ICCIDD consultation, were utilized for the survey. A confidence level of 95 per cent, a relative precision of 10 per cent and a design effect of three were taken into account for calculation of the sample size. A total of 23,348 school children in the age group 6-11 years were included in the study. The total goitre prevalence rate was found to be 12.1 per cent. The median urinary iodine excretion of the children studied was found to the 15.00 mcg/dl. About 12.7 per cent of families consumed salt with an iodine content of less than 15 ppm. The results of the present study indicated that the population of district Kangra is in a transition phase from iodine deficient to iodine sufficient nutrition and that there is a need for further strengthening of the system of monitoring the quality of iodised salt made available to the population to eliminate IDD from the Kangra Valley.

Abstract
A multitude of investigations have demonstrated the beneficial hypoglycemic effect of millets, fenugreek seeds and legumes in diabetic subjects. However, the bitter taste of fenugreek seeds and coarse nature of millets have been limitations in using them in daily dietaries. Moreover, as of today, the availability of special foods for diabetics in the Indian market is negligible. The millets, fenugreek seeds and legumes in judicious combination, after suitable processing, were used to formulate three nutritious food products--dhokla (leavened steamed cake), uppuma (kedgeree) and laddu (sweet balls), which are popular traditional snack foods in India. Evaluation of these food products for glycemic response in five normal and five diabetic subjects showed hypoglycemic effects in terms of glycemic-index (GI). The highest GI was observed for dhokla (34.96) followed by laddu (23.52) and uppuma (17.60) in normal subjects. All three food products differed significantly from each other in GI. Comparison of GI of all three food products in normal subjects with diabetes did not show significant differences (P approximately 0.05). The food products were well tolerated and acceptable to the subjects. These food products may have an important role in dietary management for diabetic people and may cater for their needs on a large scale if commercialized.

Abstract
Iodine deficiency disorders (IDD) are an important public health problem in India. Meerut district, Uttar Pradesh, is a known IDD endemic area. A study conducted in 1986 reported a total goitre rate of 24.9% in the entire population of Meerut district. During 1990-97 intensive efforts were taken by the Uttar Pradesh Government to ensure universal availability of iodized salt to the population. No survey has been conducted since 1997 on the status of iodine deficiency in the Meerut district. Hence, the present study was conducted in order to assess the prevalence of IDD and to estimate the iodine content of salt consumed in the households of Meerut district, Uttar Pradesh. The 30 cluster sampling methodology and indicators for assessment of IDD as recommended by the joint WHO/UNICEF/ICCIDD (World Health Organization/United Nations Children's Fund/International Council for the Control of Iodine Deficiency Disorders) Consultation in full was utilized for the survey. A confidence level of 95%, relative precision of 10% and design effect of three were considered in the calculation of the sample size. The prevalence of goitre at the time of survey was estimated to be 15%. A total of 6485 school children in the 6-10 years age group were selected using probability proportionate to size cluster sampling methodology. A total goitre prevalence rate of 11.6% was found in the district. It was observed that 5.4, 2.9 and 19.9% of the children had urinary excretion levels of < 2.0, 2.0-4.9, and 5.0-9.9 μg/dL, respectively. The median urinary iodine excretion of the children studied was found to be 15.0 μg/dL. Fiftythree percent of the children studied consumed salt with an iodine content of less than 15 p.p.m., which was below the stipulated level (15 p.p.m.). The study showed that the population is in a transition phase from iodine deficient (as revealed by total goitre rate) to iodine sufficient (as revealed by median urinary iodine excretion of 15.0 μg/dL). There is a need to further strengthen the existing monitoring system for the quality of iodized salt in the district in order to achieve the elimination of IDD.
