Study of effective interaction from single particle transfer reactions on f-p shell nuclei

The present study concentrates on the average effective two-body interaction matrix elements being extracted, using sum-rule techniques, from transfer reactions on target states having single orbital as well as two orbitaloccupancy. This investigation deals with transfer reactions on f-p shell nuclei involving (i) $1f_{7/2}$ and $2p_{3/2}$ transfer on target states using $^{40}$Ca as inert core, and (ii) $2p_{3/2}$ and$1f_{5/2}$ transfer on states using $^{56}$Ni as core.Comment: 12 pages, ptptex Subj-Classes: Nuclear Shell Structure e-mail:[email protected]

Effective two-body interactions in the s-d shell nuclei from sum rules equations in tranfer reactions

Average effective two-body interaction matrix elements in the s-d shell have been extracted, from data on experimentally measured isospin centroids, by combining the recently derived new sum rules equations for pick-up reactions with similar known equations for stripping reactions performed on general multishell target states. Using this combination of stripping and pick-up equations, the average effective matrix elements for the shells, 1d^2_5/2, 2s^2_1/2 and 1d^2_3/2 respectively have been obtained. A new feature of the present work is that the restriction imposed in earlier works on target states, that it be populated only by active neutrons has now been abandoned.Comment: 12 pages, RevTeX, e-mail: [email protected]

Creating Shared Value in India: How Indian Corporations Are Contributing to Inclusive Growth While Strengthening Their Competitive Advantage

Leading companies are finding new ways to accelerate growth and increase competitive advantage through innovative business models that meet societal needs at scale. These companies are "creating shared value" by using their core business processes and practices to enhance the competitiveness of companies while improving social and environmental conditions. The concept of Creating Shared Value (CSV) was introduced by the co-founders of FSG, Harvard Business School professor Michael Porter and senior fellow at the Harvard Kennedy School Mark Kramer, in several Harvard Business Review articles (most recently in January/February 2011). FSG's research in India has identified a number of highly innovative examples of shared value. In this paper, we highlight these examples and call on corporations, especially our largest ones, to lead the charge toward a strategy for growth that benefits all our citizens

Integration of ab-initio nuclear calculation with derivative free optimization technique

Optimization techniques are finding their inroads into the field of nuclear physics calculations where the objective functions are very complex and computationally intensive. A vast space of parameters needs searching to obtain a good match between theoretical (computed) and experimental observables, such as energy levels and spectra. Manual calculation defies the scope of such complex calculation and are prone to error at the same time. This body of work attempts to formulate a design and implement it which would integrate the ab initio nuclear physics code MFDn and the VTDIRECT95 code. VTDIRECT95 is a Fortran95 suite of parallel code implementing the derivative-free optimization algorithm DIRECT. Proposed design is implemented for a serial and parallel version of the optimization technique. Experiment with the initial implementation of the design showing good matches for several single-nucleus cases are conducted. Determination and assignment of appropriate number of processors for parallel integration code is implemented to increase the efficiency and resource utilization in the case of multiple nuclei parameter search

Field-effect polymer gating of low-dimensionality carbon-based materials

The work focuses on the modification of the transport properties of low-dimensional carbon based materials by tuning their surface charge carrier density (up to values of induced charge exceeding 2·10^14 carriers/cm^2) via electrochemical gating with an innovative polymer electrolyte solution. Main subjects of the study are single- and few-layer graphene systems produced by micro-mechanical exfoliation and by CVD growth respectively. Attempts to modulate the superconducting critical temperature of the graphite intercalated compounds CaC6 are also made. In addition, polymer gating was also studied on highly oriented pyrolytic graphite, for the first time, to study its properties under high charge induction

Multimedia Networks: Fundamentals and Future Directions

Multimedia has become an integral part of computing and communications environment, and networks are carrying ever-increasing volume of multimedia information. The main characteristics of multimedia information are high-volume and bursty traffic, with low tolerance to delay and delay variance. The legacy networks (designed in 70s and 80s) are not able to meet these requirements. Enhancements to the older networking technologies have been developed to convert these into multimedia networks. Enhancements to LANs include Switched Ethernet, Isochronous Ethernet, Fast Ethernet, 100VGAnyLAN, FDDI-II, and Synchronous FDDI. WAN options for multimedia networking include digital leased lines and ISDN. The Internet has revolutionized business and personal communications, but falls short of being a genuine multimedia network. To make the Internet capable of carrying multimedia traffic, new protocols such as MBone, ST-II, RTP, and RSVP have been developed. Internet2 is a new initiative that is aimed at overcoming the problems of throughput, delay and jitter encountered on the original Internet. One technology that was developed with multimedia networking as one of its main applications, is the Asynchronous Transfer Mode (ATM) technology. Upcoming Gigabit Ethernet technology will provide a path for upgrading current Ethernet networks into multimedia networks

Biological characterization of hYVH1

Human YVH1 is an atypical dual specificity phosphatase (DSP) that is widely conserved throughout evolution. Deletion studies in yeast have suggested a role for this phosphatase in regulating cell growth, sporulation, and glycogen accumulation. However, the functional role of the human orthologue is unknown. This study examines the interaction between hYVH1 and a recently identified binding partner Hsp70, in addition to deciphering domains and motifs important in hYVH1 localization. The results established that the zinc binding domain mediates the subcellular targeting of hYVH1. Moreover, a putative nuclear export sequence was identified to have some effect on the shuttling of hYVH1 between the nucleus and cytoplasm. Hsp70 and hYVH1 were found to be colocalized to the perinuclear region following heat stress. Furthermore, hYVH1 expression repressed heat shock induced cell death. The results suggest that hYVH1 cooperates with Hsp70 to positively affect cell viability by targeting the MAPK signaling pathway

Spirituality as a Moderator Between PTSS and Cardiovascular Reactivity

Posttraumatic stress symptoms (PTSS) can be distressing and produce robust cardiovascular symptoms, such as increased heart rate and blood pressure, which have been implicated in higher risk of developing cardiovascular disease (CVD). Identifying factors that may reduce symptoms may suggest therapeutic strategies. One such potential factor is spirituality, given that spirituality is associated with both reducing PTSS and with preventing or improving CVD. We sampled 63 young college women who indicated being exposed to unwanted sexual contact. We asked them to write about their experience while we took heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) measures from baseline to pre-task, during task, and post-task. The participants were given a survey to assess spirituality. Results showed that PTSS was highly correlated with decreased DBP (blunted reactivity) but was not associated with increased reactivity. Spirituality was associated with decreases in HR at all points. Our findings further suggest that spirituality was not a significant moderator between PTSS and cardiovascular reactivity measures. We hope that this study will further shed light on the relationships between sexual trauma and cardiovascular health, as well as the role of spirituality as a therapeutic device
