Resolving Octant Degeneracy at LBL experiment by combining Daya Bay Reactor Setup
Long baseline Experiment (LBL) have promised to be a very powerful
experimental set up to study various issues related to Neutrinos. Some ongoing
and planned LBL and medium baseline experiments are - T2K, MINOS, NOvA, LBNE,
LBNO etc. But the long baseline experiments are crippled due to presence of
some parameter degeneracies, like the Octant degeneracy. In this work, we first
show the presence of Octant degeneracy in LBL experiments, and then combine it
with Daya Bay Reactor experiment, at different values of CP violation phase. We
show that the Octant degeneracy in LBNE can be resolved completely with this
proposal.Comment: 4 pages, 8 figure
A neonatal septic arthritis case caused by klebsiella pneumoniae: A case report
Septic arthritis is encountered very rarely during the neonatal period and its diagnosis can delay because of atypical symptoms, thus it may lead to serious sequelae. The sequale can be prevented by early diagnosis and concomitant treatment. In neonates, pain can be experienced as a result of pseudoparalysis and of movement of the effected joints. A 17-day-old neonatal patient was brought to our hospital with complaint of unrest and then diagnosed with septic arthritis due to propagation of Klebsiella pneumoniae in joint fluid culture was represented because of the rarity of such a case. © 2016, Journal of Clinical and Diagnostic Research.

Comparative performance of some popular ANN algorithms on benchmark and function approximation problems
We report an inter-comparison of some popular algorithms within the
artificial neural network domain (viz., Local search algorithms, global search
algorithms, higher order algorithms and the hybrid algorithms) by applying them
to the standard benchmarking problems like the IRIS data, XOR/N-Bit parity and
Two Spiral. Apart from giving a brief description of these algorithms, the
results obtained for the above benchmark problems are presented in the paper.
The results suggest that while Levenberg-Marquardt algorithm yields the lowest
RMS error for the N-bit Parity and the Two Spiral problems, Higher Order
Neurons algorithm gives the best results for the IRIS data problem. The best
results for the XOR problem are obtained with the Neuro Fuzzy algorithm. The
above algorithms were also applied for solving several regression problems such
as cos(x) and a few special functions like the Gamma function, the
complimentary Error function and the upper tail cumulative
-distribution function. The results of these regression problems
indicate that, among all the ANN algorithms used in the present study,
Levenberg-Marquardt algorithm yields the best results. Keeping in view the
highly non-linear behaviour and the wide dynamic range of these functions, it
is suggested that these functions can be also considered as standard benchmark
problems for function approximation using artificial neural networks.Comment: 18 pages 5 figures. Accepted in Pramana- Journal of Physic
Thermal instability in ionized plasma
We study magnetothermal instability in the ionized plasmas including the
effects of Ohmic, ambipolar and Hall diffusion. Magnetic field in the single
fluid approximation does not allow transverse thermal condensations, however,
non-ideal effects highly diminish the stabilizing role of the magnetic field in
thermally unstable plasmas. Therefore, enhanced growth rate of thermal
condensation modes in the presence of the diffusion mechanisms speed up the
rate of structure formation.Comment: Accepted for publication in Astrophysics & Space Scienc
Vitamin D Is Required for ILC3 Derived IL-22 and Protection From Citrobacter rodentium Infection
Citrobacter rodentium is a gastrointestinal infection that requires early IL-22 from group 3 innate lymphoid cells (ILC3) for resistance. The role of vitamin D in the clearance of C. rodentium infection was tested in vitamin D sufficient (D+) and vitamin D deficient (D-) wildtype (WT) and Cyp27B1 (Cyp) KO mice (unable to produce the high affinity vitamin D ligand 1,25(OH)2D, 1,25D). Feeding Cyp KO mice D- diets reduced vitamin D levels and prevented synthesis of 1,25D. D- (WT and Cyp KO) mice had fewer ILC3 cells and less IL-22 than D+ mice. D- Cyp KO mice developed a severe infection that resulted in the lethality of the mice by d14 post-infection. T and B cell deficient D- Rag KO mice also developed a severe and lethal infection with C. rodentium compared to D+ Rag KO mice. D- WT mice survived the infection but took significantly longer to clear the C. rodentium infection than D+ WT or D+ Cyp KO mice. Treating infected D- Cyp KO mice with IL-22 protected the mice from lethality. Treating the D- WT mice with 1,25D reconstituted the ILC3 cells in the colon and protected the mice from C. rodentium. IL-22 treatment of D- WT mice eliminated the need for vitamin D to clear the C. rodentium infection. Vitamin D is required for early IL-22 production from ILC3 cells and protection from enteric infection with C. rodentium
Expandase-like activity mediated cell-free conversion of ampicillin to cephalexin by Streptomyces sp. DRS I
Cell-free extracts of Streptomyces sp.
DRS I converted ampicillin to cephalexin, presumably
due to the activity of the enzyme, expandase. The
extract was fractionated and characterized by colorimetric
and chromatographic measurements coupled
with disc-agar diffusion bioassay against an ampicillinresistant,
cephalexin-sensitive E. coli strain. Though
expandase could not be identified, the presence of
a hitherto unreported expandase in Streptomyces sp.
DRS I is suggested
Radiative corrections to deep-inelastic scattering. Case of tensor polarized deuteron
The model-independent radiative corrections to deep-inelastic scattering of
unpolarized electron beam off the tensor polarized deuteron target have been
considered. The contribution to the radiative corrections due to the
hard-photon emission from the elastic electron-deuteron scattering (the
so-called elastic radiative tail) is also investigated. The calculation is
based on the covariant parametrization of the deuteron quadrupole polarization
tensor. The numerical estimates of the radiative corrections to the
polarization observables have been done for the kinematical conditions of the
current experiment at HERAComment: 21 pages, 5 figure
Genetic and functional diversity among the antagonistic potential fluorescent Pseudomonada isolated from tea rhizosphere
Genetic and functional diversity among the antagonistic potential fluorescent Pseudomonada isolated from tea rhizosphere
Twenty-five fluorescent pseudomonads from
rhizospheric soil of six tea gardens in four district of Upper
Assam, India were isolated and screened for antagonistic
activity against fungal pathogens such as Fusarium oxysporum
f. sp. raphani (For), Fusarium oxysporum f. sp. ciceri
(Foc), Fusarium semitectum (Fs), and Rhizoctonia solani
(Rs); and bacterial pathogens 14Staphylococcus aureus
(Sa), Escherichia coli (Ec), and Klebsiella pneumoniae
(Kp). Most of the isolates exhibited strong antagonistic
activity against the fungal pathogens and gram-positive
bacterium i.e. Staphylococcus aureus. Productions of siderophore,
salicylic acid (SA), hydrogen cyanide (HCN),
and cell wall-degrading enzyme (chitinase) were studied to
observe the possible mechanisms of antagonistic activity of
the isolates. Correlation between the antagonistic potentiality
of some isolates and their levels of production of
siderophore, salicylic acid, and hydrogen cyanide was
observed. Out of the 25 isolates, antibiotic-coding genes,
2,4-diacetylphloroglucinol (DAPG) and pyoluteorin (PLT)
were detected in the isolates, Pf12 and Pf373, respectively.
Genetic diversity of these fluorescent pseudomonads were
analyzed with reference to four strains of Pseudomonas
fluorescens NICM 2099T, P. aeruginosa MTCC 2582T,
P. aureofaciens NICM 2026T, and P. syringae MTCC 673T.
16S rDNA-RFLP analysis of these isolates using three tetra
cutter restriction enzymes (HaeIII, AluI and MspI) revealed
two distinct clusters. Cluster A comprised only two isolates
Pf141 and 24-PfM3, and cluster B comprised 23 isolates
along with four reference strains
