Let $G$ be a finite graph or an infinite on which $\mathbb{Z}^d$ acts with fundamental domain. If is finite, let $\mathbf{T}$ random spanning tree chosen uniformly from all trees of $G$; if infinite, methods Pemantle show that this still makes sense, producing essential forest $G$. A method for calculating local characteristics (i.e., finite-dimensional marginals) the transfer-impedance matrix presented. This differs classical matrix-tree theorem in only small pieces ($n$-dimensional minors)...
Abstract A new protein component has been demonstrated in myelin isolated from rat whole brain and white matter dissected bovine, dog rabbit brain. It is also present optic nerve. does not appear to be other subcellular fractions of a molecular weight 20,540 ± 490(S.D.), as determined by polyacrylamide gel electrophoresis sodium dodecyl sulphate. rapid procedure for the isolation described.
Abstract— Rat brain grey and white matter were fractionated to yield myelin, nerve terminal, synaptic vesicle, terminal ‘ghost’, microsomal fractions of matter. Ester‐type glycolipids found in all except while cerebrosides occurred significant concentrations only myelin microsomes. Comparison the fatty acid profile ethanolamine‐ serine‐containing phospholipids showed marked differences between particles from matter, microsomes intermediate composition. Docosahexaenoic acid, a minor was major...
In this paper we develop a general approach for investigating the asymptotic distribution of functionals $X_n=f((Z_{n+k})_{k\in \mathbf {Z}})$ absolutely regular stochastic processes $(Z_n)_{n\in {Z}}$. Such occur naturally as orbits chaotic dynamical systems, and thus our results can be used to study probabilistic aspects systems. We first prove some moment inequalities that are analogous those mixing sequences. With their help, several limit theorems proved in rather straightforward...

This paper presents the development and evaluation of an ambient particle concentrator for conducting animal inhalation exposure studies. The system utilizes principle virtual impactors to concentrate particles in size range 0.1-2.5 microns (aerodynamic diameter; dp) by drawing them through a series three impactors. Each impactor contains majority fine mass (dp < 2.5 aerodynamic diameter) bleed flow (minor flow) that is 20% total entering impactor. have been characterized using indoor air...
During the summers of 1992 and 1993, particle mass concentrations (PM2.5 PM10) were measured at eight sites located within metropolitan Philadelphia. Particle sampling was performed simultaneously these on alternate days during summer every day seven 1993. Sampling conducted over 24-h periods beginning 9 am (EDT) both summers. All PM2.5 PM10 samples collected using 10 L/min inertial impactors with cutpoints 2.5 μm, respectively. In this paper, we examine relationship among PM2.5, coarse...
Abstract It is known that in one dimension an irreducible subshift of finite type has a unique measure maximal entropy, the so-called Parry measure. Here we give counterexample to this higher dimensions. For example, also describe geometric structure measures entropy and show there are exactly two extremal measures.

An assay of water content and specific gravity in normal pathological autopsy brain has been correlated with CCT attenuation values obtained just prior to cutting. Formalin fixation does not alter so that fixed appears be suitable for this type study. Low correlate better changes gravity, rather than infarcts, but they have a close relationship edema. The high infarcts the white matter reveals striking disparity fluid control between cortex matter, which emphasized experimental studies....

Myelin prepared from brain tissue of the developing rat (15 days post partum) can be separated into several subfractions. These are (1) ;myelin-like' and ;purified myelin', by technique Davison co-workers (Agrawal et al., 1970b) (2) ;membrane fraction,' ;light myelin' ;heavy discontinuous-sucrose-gradient procedure described in present paper. ;Myelin-like' ;membrane-fraction' subfractions appear to similar chemical properties, but different detailed morphology electron microscopy.
