Study of Heavy Quarkonium with Energy Dependent Potential  [PDF]
Pramila Gupta, Indira Mehrotra
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310189
Abstract: Heavy quark systems (c and b ) have been studied in the nonrelativistic framework using energy dependent interquark potential of the form harmonic oscillator with a small linear term as energy dependent as perturbation plus a inverse square potential. This potential admits exact analytical solution of the Schrodinger equation. Mass spectra, leptonic decay width, root mean square radii (), the expectation value of the radius (r) and <1/r> have been estimated for different quantum mechanical states for and systems. It is observed that energy dependent term in the potential leads to saturation of the mass spectra and degree of saturation is governed by the magnitude of perturbation. The calculated values of leptonic decay widths for 1s state are in very good agreement with the experimental data both for c and b systems.
Planning for Human Development—Experiences in Asia  [PDF]
Santosh Mehrotra, Sarthi Acharya
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.76109
Abstract: The Human Development paradigm states that for workers to create value and enjoy the fruits of their labour, they have to be adequately accomplished through better education, skills, adequate nutrition and health, among other factors. It makes a case for investing in people as a precondition for progress. Recent literature on development also notes that economic growth cannot be sustained without people’s inclusion. The essence of a dynamic HD framework, therefore, is that human capital, inclusion and measures to improve people’s empowerment are paramount. Much of Asia was/is labour surplus; hence, making optimal use of the labour in the growth process until the time when labour from the low productivity sectors (read: agrarian sectors) is redeployed elsewhere would be most desirable. This follows from the standard economic theories and is not new. However, the process does not automatically happen; it has to be planned and carefully executed. This paper puts forth a case for HD-based planning: a process where human capital and the economic sectors are brought into an integrated framework. In practical terms, this implies that three factors are addressed to achieve HD: agrarian reforms, industrial policy and human capital. The paper attempts to assess how select Asian countries have progressed on these counts in the recent past. It identifies the raison d’être of the high achievers’ success and the low achievers’ lack of it in the (implicit or explicit) planning process. Finally, it presents a simple model of how an HD-planning framework might look like.

AACA Element Negatively Regulates Expression of Protein Phosphatase 2C (PP2C) like Promoter in Arabidopsis thaliana  [PDF]
Purva Bhalothia, Anshu Alok, Sandhya Mehrotra, Rajesh Mehrotra
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.43071
Abstract:

Genome wide analysis of Arabidopsis thaliana reveals a unique genetic arrangement of ACGT motif in the protein phosphatase 2C (PP2C) like promoter (accession number AT5G59220). In the present study, full length, 900 base pair, 500 base pair, 400 base pair and NRM deletion variants of PP2C like promoter were constructed to investigate the activity of PP2C like promoter in the presence of inducers like abscisic acid, jasmonic acid and salicylic acid. The PP2C promoter has three ACGT elements in close vicinity. They are so positioned that they are separated by a spacer of 30 base pair and 5 base pair respectively from each other. The study has shown that ACGTN30ACGT genetic architecture is essential for the promoter to be induced in response to abscisic acid. The synergistic and antagonistic effects of cis elements were observed. AACA is a positive regulatory element in endosperm and is known to act as negative regulatory element in other tissues. In this study AACA, have been found to negatively regulate the expression of reporter gene EGFP in both induced and under uninduced conditions.

To Host or Not to Host? A Comparison Study on the Long-Run Impact of the Olympic Games
Anita Mehrotra
Michigan Journal of Business , 2012,
Abstract: Macroeconomic research on sporting mega-events, like the Olympic Games, often focuses on the short-run economic impact of individual countries. In this paper, I explore the long-run effect of the Olympics on host countries, in general. I analyze hosts in relation to "runner-up" countries, i.e. countries that come in second to the hosts in the bidding process. Upon rectifying anomalies in the data set and including control variables for the initial state of the economy and population, I find that hosts' long-run GDP per capita (GDPpc) is negative in comparison to runner-up countries' at a statistically significant level. This suggests that a one-time spike in government expenditure may lead to long-run detrimental effects: a "reverse multiplier effect" perpetuates the fall in investment demand and consumption levels back to pre-Olympic levels. My results extend the view that individual countries experience a negative economic impact, to the group of host countries in general.
Giant trochanteric pressure sore: Use of a pedicled chimeric perforator flap for cover
Mehrotra Sandeep
Indian Journal of Plastic Surgery , 2009,
Abstract: Pressure sores are increasing in frequency commensurate with an ageing population with multi-system disorders and trauma. Numerous classic options are described for providing stable wound cover. With the burgeoning knowledge on perforator anatomy, recent approaches focus on the use of perforator-based flaps in bedsore surgery. A giant neglected trochanteric pressure sore in a paraplegic is presented. Since conventional options of reconstruction appeared remote, the massive ulcer was successfully managed by a chimeric perforator-based flap. The combined muscle and fasciocutaneous flaps were raised as separate paddles based on the anterolateral thigh perforator branches and provided stable cover without complications. Perforators allow versatility in managing complex wounds without compromising on established principles.
Perforator plus flaps: Optimizing results while preserving function and esthesis
Mehrotra Sandeep
Indian Journal of Plastic Surgery , 2010,
Abstract: Background: The tenuous blood supply of traditional flaps for wound cover combined with collateral damage by sacrifice of functional muscle, truncal vessels, or nerves has been the bane of reconstructive procedures. The concept of perforator plus flaps employs dual vascular supply to flaps. By safeguarding perforators along with supply from its base, robust flaps can be raised in diverse situations. This is achieved while limiting collateral damage and preserving nerves, vessels, and functioning muscle with better function and aesthesis. Materials and Methods: The perforator plus concept was applied in seven different clinical situations. Functional muscle and fasciocutaneous flaps were employed in five and adipofascial flaps in two cases, primarily involving lower extremity defects and back. Adipofascial perforator plus flaps were employed to provide cover for tibial fracture in one patients and chronic venous ulcer in another. Results: All flaps survived without any loss and provided long-term stable cover, both over soft tissue and bone. Functional preservation was achieved in all cases where muscle flaps were employed with no clinical evidence of loss of power. There was no sensory loss or significant oedema in or distal to the flap in both cases where neurovascular continuity was preserved during flap elevation. Fracture union and consolidation were satisfactory. One patient had minimal graft loss over fascia which required application of stored grafts with subsequent take. No patient required re-operation. Conclusions: Perforator plus concept is holistic and applicable to most flap types in varied situations. It permits the exercise of many locoregional flap options while limiting collateral functional damage. Aesthetic considerations are also addressed while raising adipofascial flaps because of no appreciable donor defects. With quick operating times and low failure risk, these flaps can be a better substitute to traditional flaps and at times even free tissue transfers.
Effective Lighting Design Standards Impacting Patient Care: A Systems Approach  [PDF]
Sameer Mehrotra, Sunil Basukala, Shiva Devarakonda
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.311006
Abstract: Background: Most healthcare settings are lit by a combination of daylight entering through windows, skylights and electric-light sources. It is important to understand how these two types of light sources differ to understand their relative impacts on human health and performance. It is found important to have a starting point in healing architecture and create an environment with knowledge of users sensory and functionally needs and looks at how hospital wards can support patients’ experience or maybe even have a positive influence on the recovery process. Methods: A systematic review of the literature to evaluate the impact of light on the quality of healthcare services was conducted. Several databases were systematically searched and evaluated. Results: Majority of the studies showed that distributions of light within a space in hospitals could substantially influence the health as well as perception of people within it. The study showed that in a multi-function and diverse habitant environment such as hospital treatment rooms, lighting system design plays a major role for comfort of the patients, the critical visual requirements for hospital staff, the comfort and visual need of the visitors. In addition to these goals, energy cost savings through the careful design of lighting schemes used in such applications. Conclusions: There is consistent evidence that shows the technical, architectural and energy aspects of providing optimal lighting conditions in different areas of a healthcare facility are important for patient, staff and energy conservation and cost within the hospitals.
Parental Stress in Raising a Child with Disabilities in India
Vidya Bhushan Gupta,Priyanka Mehrotra,Naveen Mehrotra
Disability, CBR & Inclusive Development , 2012, DOI: 10.5463/dcid.v23i2.119
Abstract: Purpose: To determine the parenting stress and its determinants among parents of children with disabling conditions in India. Methods: The Parenting Stress Index – short form and a few open ended questions were administered to a convenience sample of sixty-six patient families in July, 2009 in the cities of New Delhi and Faridabad regions of Northern India through six non- governmental organizations (NGOs) that serve children with disabling conditions. Results: Female sex of the child was associated with higher stress related to failure of the child to meet parent’s expectations and to satisfy the parents in their parenting role. Parents engaged in more lucrative and prestigious occupations had more stress than parents engaged in less prestigious and lucrative occupations irrespective of their income. Many parents reported receiving little support from their extended families in taking care of their child. Religion was found to be a common coping resource used by the parents. Conclusion and Implications: Higher parenting stress in parents of girls raises the possibility of abuse and neglect. Little support from informal family resources underscores the need for developing formal resources for supporting the parents. The specific resources of parenting stress among parents of different socioeconomic status should be explored in future studies so that appropriate interventions can be planned. doi 10.5463/DCID.v23i2.119
Segment LLL Reduction of Lattice Bases Using Modular Arithmetic
Sanjay Mehrotra,Zhifeng Li
Algorithms , 2010, DOI: 10.3390/a3030224
Abstract: The algorithm of Lenstra, Lenstra, and Lovász (LLL) transforms a given integer lattice basis into a reduced basis. Storjohann improved the worst case complexity of LLL algorithms by a factor of O(n) using modular arithmetic. Koy and Schnorr developed a segment-LLL basis reduction algorithm that generates lattice basis satisfying a weaker condition than the LLL reduced basis with O(n) improvement than the LLL algorithm. In this paper we combine Storjohann’s modular arithmetic approach with the segment-LLL approach to further improve the worst case complexity of the segment-LLL algorithms by a factor of n 0.5.
