Conformation changes of the double-stranded DNA helix in response to dehydration were investigated by monitoring, by agarose gel electrophoresis, the linking number of covalently closed circular DNA generated by ligation of linear DNA in the presence of different organic solvents or different temperatures. It was found that: (i) The DNA helix unwinds upon addition of certain organic solvents or...

The binding of three competitive glutathione analogue inhibitors (S-alkylglutathione derivatives) to glutathione S-transferase from Schistosoma japonicum, SjGST, has been investigated by isothermal titration microcalorimetry at pH 6.5 over a temperature range of 15--30 degrees C. Calorimetric measurements in various buffer systems with different ionization heats suggest that no protons are exch...

GABA(A) receptor fast desensitization is thought to shape the time course of individual IPSCs. Although GABA(A) receptors also exhibit slower phases of desensitization, the possible role of slow desensitization in modifying synaptic function is poorly understood. In transiently transfected human embryonic kidney (HEK293T) cells, rat alpha1beta3delta and alpha1beta3gamma2L GABA(A) receptors show...

We study second to fourth order numerical methods to a type of delta function integrals in one to three dimensions. These delta function integrals arise from recent efficient level set methods for computing the multivalued solutions of nonlinear PDEs. We show that the natural quadrature approach with usual discrete delta functions and support size formulas to the two dimensional delta function ...

lim t→s+ Γij(t, x, s, ·) = δijδx(·), Γij(·, ·, s, y) = 0 on ∂U = R × ∂Ω, where δij is the Kronecker delta symbol, δ(s,y)(·, ·) and δx(·) are Dirac delta functions. In particular, when U = R, the Green’s matrix (or Green’s function) is called the fundamental matrix (or fundamental solution). We prove that if weak solutions of (P) satisfy an interior Hölder continuity estimate (see Section 2.5 fo...

We investigate the decay properties of some beauty and charm mesons with a phenomenological potential model. First, we consider nonrelativistic Hamiltonian mesonic system Coulomb plus exponential terms study wave function energy using variational approach. Thereby, compute masses, constants, leptonic branching fractions heavy–light mixing mass parameter $$\Delta {m_{{B_q}}}$$ . radiative widths...

The effect of temperature on the apparent equilibrium constant of creatine kinase (ATP:creatine N-phosphotransferase (EC 2.7.3.2)) was determined. At equilibrium the apparent K' for the biochemical reaction was defined as [formula: see text] The symbol sigma denotes the sum of all the ionic and metal complex species of the reactant components in M. The K' at pH 7.0, 1.0 mM free Mg2+, and ionic ...

In this paper we consider memoryless one-bit compressed sensing with randomly subsampled Gaussian circulant matrices. We show that in a small sparsity regime and for small enough accuracy $\delta$, $m\sim \delta^{-4} s\log(N/s\delta)$ measurements suffice to reconstruct the direction of any $s$-sparse vector up to accuracy $\delta$ via an efficient program. We derive this result by proving that...

Through an extensive series of high-precision numerical computations the optimal complete photonic band gap (PBG) as a function dielectric contrast $\ensuremath{\alpha}$ for variety crystal and disordered heterostructures, we reveal striking universal behaviors sensitivity $\mathcal{S}(\ensuremath{\alpha})\ensuremath{\equiv}d\mathrm{\ensuremath{\Delta}}(\ensuremath{\alpha})/d\ensuremath{\alpha}...

This prospective, longitudinal study examined the effects of participation in team-based exercise training on cardiac structure and function. Competitive endurance athletes (EA, n = 40) and strength athletes (SA, n = 24) were studied with echocardiography at baseline and after 90 days of team training. Left ventricular (LV) mass increased by 11% in EA (116 +/- 18 vs. 130 +/- 19 g/m(2); P < 0.00...
