Radiation reaction force induced nonlinear mixing of Raman sidebands of an ultra-intense laser pulse in a plasma
Stimulated Raman scattering of an ultra-intense laser pulse in plasmas is
studied by perturbatively including the leading order term of the
Landau-Lifshitz radiation reaction force in the equation of motion for plasma
electrons. In this approximation, radiation reaction force causes phase shift
in nonlinear current densities that drive the two Raman sidebands (anti-Stokes
and Stokes waves), manifesting itself into the nonlinear mixing of two
sidebands. This mixing results in a strong enhancement in the growth of the
forward Raman scattering instability
Evaluation of sweet taste sensitivity in type-II Diabetes Mellitus patients
Background: The objective is to evaluate the sweet taste sensitivity among type-II diabetes mellitus patients.
Methods: This is a cross sectional study consisted of 227 subjects (127 type-II Diabetic patients & 100 non diabetic individuals) of both the genders and age matched. Sweet taste sensitivity tests were done using different concentrations of glucose solution and compared among the diabetic patients with FBS more than 180mg/dl and diabetic patients with FBS less than 180mg/dl and also compared among the diabetic patients and non diabetic individuals. The final concentration at which patient was able to perceive the taste was recorded. statistical analysis was done using Student’s unpaired T test. PÂvalues of < 0.05 were considered to be statistically significant.
Results: The mean of sweet taste sensitivity among diabetic patients with FBS >180 mg/dl was 6245 mg/l and the mean of sweet taste sensitivity in the diabetic patients with FBS <180 mg/dl was 2249mg/l with P<0.001 which is significant. The mean of sweet taste sensitivity among diabetic patients with FBS >180 mg/dl was 6245mg/l and the mean of sweet taste sensitivity in the non diabetic individuals was 1979mg/l with P<0.01 which is significant. the mean of sweet taste sensitivity among diabetic patients with FBS <180 mg/dl was 2249 mg/l and the mean of sweet taste sensitivity in the non diabetic individuals was 1979mg/l with P>0.05 which is not significant.
Conclusion: In our study it was concluded that type-II Diabetes Mellitus patients have lesser sensitivity for the sweet taste. Loss of sensitivity leads to the increase in sugar consumption being the risk factor for worsening the disease

Novel aspects of radiation reaction in the classical and the quantum regime
This work is dedicated to the study of radiation reaction signatures in the
framework of classical and quantum electrodynamics. Since there has been no
distinct experimental validation of radiation reaction and its underlying
equations so far and its impact is expected to be substantial for the
construction of new experimental devices, e.g., quantum x-free electron lasers,
a profound understanding of radiation reaction effects is of special interest.
Here, we describe how the inclusion of quantum radiation reaction effects
changes the dynamics of ultra-relativistic electron beams colliding with
intense laser pulses significantly. Thereafter, the angular distribution of
emitted radiation is demonstrated to be strongly altered in the quantum
framework, if in addition to single photon emission also higher order photon
emissions are considered. Furthermore, stimulated Raman scattering of an
ultra-intense laser pulse in plasmas is examined and forward Raman scattering
is found to be significantly increased by the inclusion of radiation reaction
effects in the classical regime. The numerical simulations in this work show
the feasibility of an experimental verification of the predicted effects with
presently available lasers and electron accelerators.Comment: 13 pages, 3 figures, Proceedings of the LPHYS'13 Worksho

Generalised Shastry-Sutherland Models in three and higher dimensions
We construct Heisenberg anti-ferromagnetic models in arbitrary dimensions
that have isotropic valence bond crystals (VBC) as their exact ground states.
The d=2 model is the Shastry-Sutherland model. In the 3-d case we show that it
is possible to have a lattice structure, analogous to that of SrCu_2(BO_3)_2,
where the stronger bonds are associated with shorter bond lengths. A dimer mean
field theory becomes exact at d -> infinity and a systematic 1/d expansion can
be developed about it. We study the Neel-VBC transition at large d and find
that the transition is first order in even but second order in odd dimensions.Comment: Published version; slightly expande
Occurrence of multiple combinations of G and P types of group A bovine and human rotaviruses in Uttarakhand and Nagaland states, India
The present study describes the distribution of RV in bovine and human population from Uttarakhand and North eastern region of India. Group A rotavirus (RVA) was detected in 17.33% and 15.68% diarrhoeic cases from bovine and humans, respectively. All bovine RVA isolates were long electropherotypes whereas, in human RVA isolates both long and short electropherotypes were detected. Genotyping by multiplex RT-PCR revealed presence of G3 and G10 genotypes in bovine and G1 and G3 in humans. Among P types, P[1] and P[11] in bovine and P[4] and P[8] in human were detected. The G and P type combinations present were G3P[11], G10P[1], G3P[1]P[11], G10P[1]P[11], G3G10P[1]P[11], G3G6G10P[1] and G3G6G10P[11] in bovine, while G1P[4], G3P[8] and G1G3P[8] in human samples
Lepton polarization asymmetry in radiative dileptonic B-meson decays in MSSM
In this paper we study the polarization asymmetries of the final state lepton
in the radiative dileptonic decay of B meson (\bsllg) in the framework of
Minimal Supersymmetric Standard Model (MSSM) and various other unified models
within the framework of MSSM e.g. mSUGRA, SUGRA (where condition of
universality of scalar masses is relaxed) etc. Lepton polarization, in addition
of having a longitudinal component (\pl), can have two other components, \pt
and \pn, lying in and perpendicular to the decay plane, which are proportional
to \ml and hence are significant for final state being or
. We analyse the dependence of these polarization asymmetries
on the parameters of the various models.Comment: typos corrected to match with published versio
