Trends and Determinants of Unmet Need for Family Planning in Bihar (India): Evidence from National Family Health Surveys  [PDF]
Amit Kumar, Aditya Singh
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.32021
Abstract:

Using data from all three rounds of the National Family Health Survey, this study examines the trends and determinants of unmet need for family planning in the state of Bihar. Bivariate analysis was carried out to examine the level and trends of unmet need for family. Binary logistic regression was used to examine the factor affecting unmet need for family planning. About 25% of the currently married women, aged 15 - 49 years, in Bihar at present have an unmet need for family planning services, 11% for spacing and 12% for limiting. Only 18% of total demand for spacing methods is met compared to about 72% of total demand for limiting methods. The unmet need for family planning among Muslim (32%), rural (24%) and adolescent (36%) and poor women (26%) is relatively higher than other groups. Religious prohibition and husband opposed were the main reasons for not using contraception. A considerable proportion of older women (45 - 49 years) and those living in urban areas cited method-related reasons. About 86% of Muslim women cited opposition to use as the main reason for not using family planning. The same is also substantiated by logistic regression analysis where the odds of unmet need were significantly higher among Muslim women (OR = 1.88; p < 0.05). Women from Other Backward Castes (OR = 0.74; p

Pseudoaneurysm of Ascending Aorta with Extrinsic Compression of Left Main Coronary Artery  [PDF]
Kumar Aditya, Rohit Kumar, Harpreet Singh Minhas
World Journal of Cardiovascular Surgery (WJCS) , 2016, DOI: 10.4236/wjcs.2016.63008
Abstract: Pseudoaneurysm of ascending aorta carries high mortality and morbidity due to adhesions and compression over surrounding structures. It occurs either after some form of injury to aorta or after infectious pathology. Spontaneous pseudoaneuryms are very rare as are the extrinsic compression of left main coronary artery. We are presenting a case with both of these rare ties. Patient was a female of middle age presented with cough and a past history of treated pulmonary tuberculosis 12 years before. During evaluation by X-ray, CECT is a large pseudoaneurysm of ascending aorta with oval defect in posterior wall above sinotubular junction. It was compressing 90% of the left main coronary artery, occluding 100% of the right pulmonary artery with formation of collaterals to it from surrounding arteries. Active tuberculosis and syphilis were ruled out. Patient underwent excision of pseudoaneurysm, replacement of ascending aorta by Dacron graft and coronary artery bypass under TRCA and CPB. There was massive intraoperative bleeding, and patient died on the fourth day due to sepsis and ARDS.

A Wavelet Transform Algorithm for 2n Shades Image
Aditya Kumar,,Pardeep Singh
International Journal on Computer Science and Engineering , 2011,
Abstract: Wavelet anatomization is globally appreciated up to the sixtieth part of an hour tools for timefrequency. It acquires an exceptional development based on Fourier fractionation and plays a consequential character in the signal processing remarkably in image compression. By analyzing the relations of the coefficients between every main block and the complete image, we can locate the catalogue location of the sub-band of each son block in the same sub-band of the whole image is same as that of the son block in the origin image. Many image compression algorithms (lossy or lossless) have already been devised adhering to their perspective point of view. In this paper we propose conceptually an algorithm for image compression for minimizing a number of bits for storing an image into disk and reducing spatial redundancy and correlation between pixels.
Decomposing the Gap in Childhood Undernutrition between Poor and Non–Poor in Urban India, 2005–06
Abhishek Kumar, Aditya Singh
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0064972
Abstract: Background Despite the growing evidence from other developing countries, intra-urban inequality in childhood undernutrition is poorly researched in India. Additionally, the factors contributing to the poor/non-poor gap in childhood undernutrition have not been explored. This study aims to quantify the contribution of factors that explain the poor/non-poor gap in underweight, stunting, and wasting among children aged less than five years in urban India. Methods We used cross-sectional data from the third round of the National Family Health Survey conducted during 2005–06. Descriptive statistics were used to understand the gap in childhood undernutrition between the urban poor and non-poor, and across the selected covariates. Blinder–Oaxaca decomposition technique was used to explain the factors contributing to the average gap in undernutrition between poor and non-poor children in urban India. Result Considerable proportions of urban children were found to be underweight (33%), stunted (40%), and wasted (17%) in 2005–06. The undernutrition gap between the poor and non-poor was stark in urban India. For all the three indicators, the main contributing factors were underutilization of health care services, poor body mass index of the mothers, and lower level of parental education among those living in poverty. Conclusions The findings indicate that children belonging to poor households are undernourished due to limited use of health care services, poor health of mothers, and poor educational status of their parents. Based on the findings the study suggests that improving the public services such as basic health care and the education level of the mothers among urban poor can ameliorate the negative impact of poverty on childhood undernutrition.
Two Quarantine Models on the Attack of Malicious Objects in Computer Network
Bimal Kumar Mishra,Aditya Kumar Singh
Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/407064
Abstract: SEIQR (Susceptible, Exposed, Infectious, Quarantined, and Recovered) models for the transmission of malicious objects with simple mass action incidence and standard incidence rate in computer network are formulated. Threshold, equilibrium, and their stability are discussed for the simple mass action incidence and standard incidence rate. Global stability and asymptotic stability of endemic equilibrium for simple mass action incidence have been shown. With the help of Poincare Bendixson Property, asymptotic stability of endemic equilibrium for standard incidence rate has been shown. Numerical methods have been used to solve and simulate the system of differential equations. The effect of quarantine on recovered nodes is analyzed. We have also analyzed the behavior of the susceptible, exposed, infected, quarantine, and recovered nodes in the computer network.

Aditya Singh,Abhishek Kumar,Amit Kumar
PeerJ , 2013, DOI: 10.7717/peerj.75
Abstract: Background. Despite the growing share of neonatal mortality in under-5 mortality in the recent decades in India, most studies have focused on infant and child mortality putting neonatal mortality on the back seat. The development of focused and evidence-based health interventions to reduce neonatal mortality warrants an examination of factors affecting it. Therefore, this study attempt to examine individual, household, and community level factors affecting neonatal mortality in rural India. Data and methods. We analysed information on 171,529 singleton live births using the data from the most recent round of the District Level Household Survey conducted in 2007–08. Principal component analysis was used to create an asset index. Two-level logistic regression was performed to analyse the factors associated with neonatal deaths in rural India. Results. The odds of neonatal death were lower for neonates born to mothers with secondary level education (O R = 0.60, p = 0.01) compared to those born to illiterate mothers. A progressive reduction in the odds occurred as the level of fathers’ education increased. The odds of neonatal death were lower for infants born to unemployed mothers (O R = 0.89, p = 0.00) compared to those who worked as agricultural worker/farmer/laborer. The odds decreased if neonates belonged to Scheduled Tribes (O R = 0.72, p = 0.00) or ‘Others’ caste group (O R = 0.87, p = 0.04) and to the households with access to improved sanitation (O R = 0.87, p = 0.02), pucca house (O R = 0.87, p = 0.03) and electricity (O R = 0.84, p = 0.00). The odds were higher for male infants (O R = 1.21, p = 0.00) and whose mother experienced delivery complications (O R = 1.20, p = 0.00). Infants whose mothers received two tetanus toxoid injections (O R = 0.65, p = 0.00) were less likely to die in the neonatal period. Children of higher birth order were less likely to die compared to first birth order. Conclusion. Ensuring the consumption of an adequate quantity of Tetanus Toxoid (TT) injections by pregnant mothers, targeting vulnerable groups like young, first time and Scheduled Caste mothers, and improving overall household environment by increasing access to improved toilets, electricity, and pucca houses could also contribute to further reductions in neonatal mortality in rural India. Any public health interventions aimed at reducing neonatal death in rural India should consider these factors.
Utilization of maternal healthcare among adolescent mothers in urban India: evidence from DLHS-3
Aditya Singh,Abhishek Kumar,Pragya Pranjali
PeerJ , 2015, DOI: 10.7717/peerj.592
Abstract: Background. Low use of maternal healthcare services is one of the reasons why maternal mortality is still considerably high among adolescents mothers in India. To increase the utilization of these services, it is necessary to identify factors that affect service utilization. To our knowledge, no national level study in India has yet examined the issue in the context urban adolescent mothers. The present study is an attempt to fill this gap.
Selfish Distributed Compression over Networks: Correlation Induces Anarchy

Mathematics , 2008,
Abstract: We consider the min-cost multicast problem (under network coding) with multiple correlated sources where each terminal wants to losslessly reconstruct all the sources. We study the inefficiency brought forth by the selfish behavior of the terminals in this scenario by modeling it as a noncooperative game among the terminals. The degradation in performance due to the lack of regulation is measured by the {\it Price of Anarchy} (POA), which is defined as the ratio between the cost of the worst possible \textit{Wardrop equilibrium} and the socially optimum cost. Our main result is that in contrast with the case of independent sources, the presence of source correlations can significantly increase the price of anarchy. Towards establishing this result, we first characterize the socially optimal flow and rate allocation in terms of four intuitive conditions. Next, we show that the Wardrop equilibrium is a socially optimal solution for a different set of (related) cost functions. Using this, we construct explicit examples that demonstrate that the POA $> 1$ and determine near-tight upper bounds on the POA as well. The main techniques in our analysis are Lagrangian duality theory and the usage of the supermodularity of conditional entropy.

International Journal of Soft Computing & Engineering , 2012,
Abstract: Low power VLSI circuits have become important criteria for designing the energy efficient electronic designs for high performance and portable devices .The multipliers are the main key structure for designing an energy efficient processor where a multiplier design decides the digital signal processors efficiency. In this paper, 4*4 unsigned Array and Tree multiplier architecture is being designed by using 1-bit full adders and AND2 function following various logic styles. The full adders and AND2 function have been designed using various logic styles following a unique pattern of structure to improve their performance in various means like less transistors, low power, minimal delay, and increased power delay product. The various types of adders used in our paper are complementary MOS (CMOS) logic style, complementary pass-transistor (CPL) logic style and double-pass transistor (DPL) logic style. The main objective of our work is to calculate the average power, delay and power delay product of 4*4 bit multipliers following various logic styles at 5v supply voltage at 25c temperature with 0.15um technology and simulating them with T-spice of Tanner EDA tool. An multiplier architecture is designed using full adder, half adder structure and AND2 function and then the above said various logic style adders and AND2 function are replaced in the multiplier architecture and then their outputs are generated, such that their average power, delay, and power delay product are calculated.
