Increased Blood Levels of NfL, GFAP, and Placental Growth Factor After Radiotherapy to the Brain

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT In this study, we analyzed biomarkers of neuronal, glial, and vascular injury in longitudinal paired samples of blood and cerebrospinal fluid after prophylactic cranial irradiation in patients with small cell lung cancer. Neurofilament light chain protein (NfL) and glial fibrillary acidic protein (GFAP) increased in serum and cerebrospinal ...

Deformaciones isométricas infinitesimales de superficies multidimensionales ensambladas

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
The article introduces the concept of multidimensional pasted surfaces and considers the case of different dimensions in the surfaces to be pasted. Infinitesimal deformations of such surfaces are also considered.

An approach to BPS black hole microstate counting in an N = 2 STU model

open access: yesJournal of High Energy Physics, 2020
We consider four-dimensional dyonic single-center BPS black holes in the N = 2 STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars S, T , U are taken to be large, we evaluate the ...

Quaternionic CR Geometry

open access: yes, 2013
Modelled on a real hypersurface in a quaternionic manifold, we introduce a quaternionic analogue of CR structure, called quaternionic CR structure.

On organizing principles of Discrete Differential Geometry. Geometry of spheres

open access: yes, 2006
Discrete differential geometry aims to develop discrete equivalents of the geometric notions and methods of classical differential geometry. In this survey we discuss the following two fundamental Discretization Principles: the transformation group ...

Finite Lattices Generating Not Finitely–Based and Nonstandard Quasivarieties

open access: yesJournal of Mathematics
There are two well-known and closely related problems in lattice theory: Which finite lattices generate finitely-based quasivarieties? and Which finite lattices generate standard quasivarieties?

Circular-geometry oscillators [PDF]

open access: yes, 2004
5.3GHz 0.18μm CMOS circular-geometry oscillator exploits high Q of slab inductors. The oscillator draws 10mA from 1.4V with a phase noise of -147.3dBc/Hz at 10MHz offset. A second 5.4GHz circular-geometry VCO has a tuning range of 8% with phase noise of -
