The 12,460-Year Hohenheim Oak and Pine Tree-Ring Chronology from Central Europe—A Unique Annual Record for Radiocarbon Calibration and Paleoenvironment Reconstructions
The combined oak and pine tree-ring chronologies of Hohenheim University are the backbone of the Holocene radiocarbon calibration for central Europe. Here, we present the revise...
Physical performance of a positron tomograph for brain imaging with retractable septa
Performance characteristics of a new design of positron tomograph with automatically retractable septa for brain imaging have been studied. The device, consisting of block BGO d...
Deep Belief Networks using discriminative features for phone recognition
Deep Belief Networks (DBNs) are multi-layer generative models. They can be trained to model windows of coefficients extracted from speech and they discover multiple layers of fe...
STRIATONIGRAL DEGENERATION
The clinical and pathological features of 10 cases of striatonigral degeneration are described: 5 were misdiagnosed in life as Parkinson's disease. Retrospectively, helpful earl...
THE LEFT MEDIAL TEMPORAL REGION AND SCHIZOPHRENIA: A PET STUDY
Regional cerebral blood flow (rCBF) was measured in 30 schizophrenic patients with severe, persistent and stable symptoms using positron emission tomography (PET). Directed and ...
CALIBRATING DIVERGENCE TIMES ON SPECIES TREES VERSUS GENE TREES: IMPLICATIONS FOR SPECIATION HISTORY OF APHELOCOMA JAYS
Estimates of the timing of divergence are central to testing the underlying causes of speciation. Relaxed molecular clocks and fossil calibration have improved these estimates; ...
Causal Variables, Indicator Variables and Measurement Scales: An Example from Quality of Life
Summary There is extensive literature on the development and validation of multi-item measurement scales. Much of this is based on principles derived from psychometric theory an...
INFORMATION THEORY AND STIMULUS‐INDEPENDENT THOUGHT
The production of stimulus‐independent thought (e.g. fantasy and imagery) was measured as a function of the rate at which information was presented to human subjects. Informatio...
On the Scientific Evaluation of Diagnostic Procedures
Diagnosis is the cornerstone of modern clinical medicine. It requires accurate observation and rational deduction. In its most complete form it is the process of identifying a d...
