V(H)12 B cells undergo stringent selection at multiple checkpoints to favor development of B-1 cells that bind phosphatidylcholine. Selection begins with the V(H) third complementarity-determining region (CDR3) at the pre-B cell stage, in which most V(H)12 pre-B cells are selectively eliminated, enriching for those with V(H)CDR3s of 10 aa and a fourth position Gly (designated 10/G4). To underst...

In this paper we investigate a class of integro-differential equations οn Banach space with nonlocal and initial boundary conditions in terms an abstract operator equation
 B1 x=Ax-S0 F(A x)-G0 Φ(Ax)=f ,x∈D(B1) (1) 
 where A, A are linear operators, S0, G0 vectors Φ, F the functional vectors. The under study has decomposition form B1=B0 B B0 being different operators special forms. Me...

PURPOSE Direct intraoral scanning and superimposing methods have recently been applied to measure the dimensions of periodontal tissues. The aim this study was analyze various correlations between labial gingival thickness underlying alveolar bone thickness, as well clinical parameters among 3 tooth types (central incisors, lateral canines) using a digital method. METHODS In 20 periodontally he...

After decades of continuous scaling, further advancement complementary metal-oxide-semiconductor (CMOS) technology across the entire spectrum computing applications is today limited by power dissipation, which scales with square supply voltage. Here, an atomic-scale tin transistor demonstrated to perform conductive switching between bistable configurations on/off potentials ≤2.5 mV in magnitude...

The presence of hydrogen can affect elastic properties and seismic velocities of minerals in the Earth's upper mantle. In this study, the secondorder elastic constants of hydrous wadsleyites containing 0.37, 0.84, and 1.66 wt.% H2O were determined by Brillouin scattering at ambient conditions. Measurements were performed on at least three independent crystal planes for each composition. The agg...

In the present study, microspectrofluorometry and digital imaging procedures were used to investigate by fluorescence Resonance Energy Transfer (FRET) analysis the changes of chromatin organization during the transition from G0 quiescent stat to G1 phase. G0 transition is a key event in cell cycle progress depending on the activation of specific genes and the concomitant silencing of others, wh...

In this paper, we study the boundary controllability of the Gear–Grimshaw system posed on a finite domain (0, L), with Neumann boundary conditions: ⎧ ⎪⎪⎪⎪⎨ ⎪⎪⎪⎪⎩ ut + uux + uxxx + avxxx + a1vvx + a2(uv)x = 0, in (0, L)× (0, T ), cvt + rvx + vvx + abuxxx + vxxx + a2buux + a1b(uv)x = 0, in (0, L)× (0, T ), uxx(0, t) = h0(t), ux(L, t) = h1(t), uxx(L, t) = h2(t), in (0, T ), vxx(0, t) = g0(t), vx(L...

Photodynamic therapy (PDT) involves the action of photons on photosensitive molecules, where atomic oxygen or OH(-) molecular species are locally released on pathogenic human cells, which are mainly carcinogenic, thus causing cell necrosis. The efficacy of PDT depends on the local nanothermodynamic conditions near the cell/nanodrug system that control both the level of intracellular translocati...

The algebraic conditions that specific gaugedG/H-WZWmodel have to satisfy in order to give rise to Non-Abelian Toda models with non singular metric with or without torsion are found. The classical algebras of symmetries corresponding to grade one rank 2 and 3 singular NA-Toda models are derived. The proliferation of different two dimensional G0-Toda theories ([2] [10] ) addresses the question a...
