background: for radiotherapy of total skin including sub-cutaneous tissue up to a depth of 3 cm on the entire left leg of an adult (angiosarcoma skin), a complex treatment with multiple stationary electron fields was planned at our clinic. the details of dosimetry, clinical dose measurements are presented. materials and methods: the treatment planned with 6 overlapping 9 mev electron fields in ...

The acquisition of accurate channel state information at the transmitter (CSIT) is a difficult task in multiple-input multiple-output (MIMO) systems. Partial CSIT is a more realistic assumption, especially for high-mobility mobile users (MUs) whose channel varies very rapidly. In this letter, we propose a MIMO two-way relaying (MTWR) scheme, in which the communication between the BS and a high-...

The paper is concerned with the following chemotaxis system nonlinear motility functions style='text-indent:20px;'> \begin{document}$\begin{equation}\label{0-1}\begin{cases}u_t = \nabla \cdot (\gamma(v)\nabla u- u\chi(v)\nabla v)+\mu u(1-u), &x\in \Omega, ~~t>0, \\ 0 \Delta v+ u-v, & x\in \\u(x, 0) u_0(x), \end{c...

This study aimed to compare fixed-field, intensity-modulated radiotherapy (f-IMRT) with intensity-modulated arc therapy (IMAT) treatment plans in dosimetry and practical application for cervical esophageal carcinoma. For ten cervical esophageal carcinoma cases, f-IMRT plan (seven fixed-fields) and two IMAT plans, namely RA (coplanar 360° arcs) and RAx (coplanar 360° arcs without sectors from 80...

Classical molecular dynamics is applied to the rotation of a dipolar molecular rotor mounted on a square grid and driven by rotating electric field E(nu) at T approximately 150 K. The rotor is a complex of Re with two substituted o-phenanthrolines, one positively and one negatively charged, attached to an axial position of Rh(2)(4+) in a [2]staffanedicarboxylate grid through 2-(3-cyanobicyclo[1...

Progression of pro-B lymphocytes to the pre-B stage depends on the expression of a pre-B cell receptor (pre-BCR), consisting of an Ig mu H chain, Ig surrogate light chain, and associated signal transducing chains. Mice that are unable to express a pre-BCR show an arrest of B cell development at the pro-B stage. Such is the case for severe combined immune deficient (SCID) mice in which mu chains...

Early B cell development depends upon the surface expression of Ig heavy chain protein (mu) in a signaling complex known as the pre-B cell receptor (pre-BCR). In addition to mu, the pre-BCR consists of the surrogate light chains VpreB and lambda5 and the transmembrane signal transduction proteins Ig-alpha and Ig-beta. Expression of this complex is associated with changes in surface marker expre...

Abstract We study the integrability of 2D Hamiltonian systems $$H_\mu =\frac{1}{2}(p_1^2+p_2^2) + \omega (p_1q_2-p_2q_1) -\tfrac{\mu }{r}+ V(q_1,q_2)$$ H μ = 1 2 ( ...

Dust permeates the interstellar medium, reddening and polarizing background starlight, but dust properties vary with local environment. In order to characterize in a highly irradiated diffuse cloud, we measure optical polarization towards 27 stars surrounding mid-latitude $b$=$+$24$^{\circ}$ O9.2IV star $\zeta$ Ophiuchi, using new spectroscopy polarimetry. We incrementally deredden depolarize d...

We show that the energy gap for BCS equation is $ \Xi = \mu \left( 8 e^{-2} + o(1)\right) \exp\left( \frac{\pi}{2\sqrt{\mu} a}\right) in low density limit $\mu \to 0$. Together with similar result critical temperature [arXiv:0803.3324] this shows that, limit, ratio of and a universal constant independent interaction potential $V$. The results hold class potentials negative scattering length $a$...
