James Collier, in 1904, gave one of the best early accounts of tonsillar herniation as a terminal event caused by raised intracranial pressure. He also observed false localizing signs. Adolf Meyer added to the picture, describing detailed pathology of tentorial and subfalcial herniation, and hemianopia as a false localizing sign. In 1929, Kernohan and Woltman published their important work on i...

We report a female patient with delayed growth and development, skeletal and cardiac defects, and a male XY sex chromosome complement with early failure of gonad development. SRY sequencing was normal. Array comparative genome hybridization (CGH) analysis revealed a gain in copy number in the subtelomeric region of the short arm of chromosome 16, encompassing a region of approximately 560 kb in...

BACKGROUND The aim of this study was to analyze the effects of a multidisciplinary program carried out in a chronic ventilator facility on disability, autonomy, and nursing needs of patients after a prolonged ICU stay. Secondary outcome measures were survival, weaning rate, chronic ventilator facility stay, and discharge destination. METHODS Multidisciplinary assessment, clinical stabilizatio...

One in five adults in the United States is functionally innumerate; they do not possess the mathematical competencies needed for many modern jobs. We administered functional numeracy measures used in studies of young adults' employability and wages to 180 thirteen-year-olds. The adolescents began the study in kindergarten and participated in multiple assessments of intelligence, working memory,...

Hard X-ray observations are crucial to study the non-thermal jet emission from high-redshift, powerful blazars. We observed two bright z > 2 flat-spectrum radio quasars (FSRQs) in hard X-rays to explore the details of their relativistic jets and their possible variability. S5 0014+81 (at z = 3.366) and B0222+185 (at z = 2.690) have been observed twice by the Nuclear Spectroscopic Telescope Arra...

We analyze the constraints of general coordinate invariance for quantum theories possessing conformal symmetry in four dimensions. The character of these constraints simplifies enormously on the Einstein universe R× S. The SO(4, 2) global conformal symmetry algebra of this space determines uniquely a finite shift in the Hamiltonian constraint from its classical value. In other words, the global...

The possibility of using sendust (FeAlSi) as the soft magnetic underlayer for hexagonal barium ferrite (BaM) and strontium ferrite (SrM) was studied. Sendust films were found to retain their soft magnetic properties with a rapid thermal anneal (RTA) at 800 C for 60 s, which is necessary to crystallize the as-deposited amorphous BaM and SrM films. Several film structures with sendust films as th...

We supplement the discussion of Moore and Reshetikhin and others by finding new semiclassical nonabelian vertex operators for the chiral, antichiral and nonchiral primary fields of WZW theory. These new nonabelian vertex operators are the natural generalization of the familiar abelian vertex operators: They involve only the representation matrices of Lie g, the currents of affine (g × g) and ce...

’t Hooft construction of free energy, electric and magnetic fluxes, and of the partition function with twisted boundary conditions, is extended to the case of N = 4 supersymmetric Yang-Mills theories based on arbitrary compact, simple Lie groups. The transformation of the fluxes and the free energy under S-duality is presented. We consider the partition function of N = 4 for a particular choice...

We discuss a number of quantile-based risk measures (QBRMs) that have recently been developed in the financial risk and actuarial/insurance literatures. The measures considered include the Value-at-Risk (VaR), coherent risk measures, spectral risk measures, and distortion risk measures. We discuss and compare the properties of these different measures, and point out that the VaR is seriously fl...
