Digital Cognitive Phenotyping for Differential Diagnosis and Monitoring in Neurological Conditions
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To assess the utility, accessibility, and equivalence to supervised scales of online cognitive assessment in older individuals with cognitive impairment. Methods Patients with Alzheimer's disease (AD, n = 31), idiopathic normal pressure hydrocephalus (iNPH, n = 26), and traumatic brain injury (TBI, n = 23) completed online cognitive ...

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

Geochemical Phase Diagrams and Gale Diagrams
SIAM Journal on Applied Mathematics, 2003The paper presents an application of linear and affine Gale diagrams and the secondary fan of a point configuration to chemistry. The authors provide a glossary of corresponding terms from discrete geometry and chemistry and define those terms in a way accessible to readers from both communities; this includes all emphasized terms in this review ...

Physical Review E, 1994
We map the phase diagram of microtubules as a function of temperature and tubulin concentration. We observe spontaneous and site-nucleated microtubule assembly. At temperatures and concentrations below the onset of spontaneous nucleation, we measure the steady-state proportion of occupied nucleation sites and the distribution of lengths of site ...

Journal of Phase Equilibria, 1991
This section is intended to provide the most current phase diagram data. Guidelines for the inclusion of new information in this section are (1) systems for which no phase diagrams are given in Binary A Uoy Phase Diagrams, second edition; (2) complete diagrams that are substantially different from earlier versions published in Binary Alloy Phase ...

Melting and freezing have been one of the most fascinating phenomena in daily life. Abrupt changes occur in the properties of a substance when it is heated through its melting point. Such phase transitions have been studied since the beginning of experiments and many attempts have been made to formulate a general theory of melting.

Algorithmic phase diagrams are a neat and compact representation of the results of comparing the execution time of several algorithms for the solution of the same problem. As an example we show the recent results of Gannon and Van Rosendale on the solution of multiple tridiagonal systems of equations in the form of such diagrams.

Journal of the Less Common Metals, 1983
Abstract The Th-Sn system was investigated by means of differential thermal and X-ray analysis and micrography. Two eutectics are formed at about 80.0 at.% Th and 1.0 at.% Th with characteristic temperatures of 1600 °C and 220 °C respectively. Four intermetallic compounds (Th5Sn3, Th5Sn4, ThSn2 and ThSn3) were found and the crystal structures of all ...

Phase Coexistence in a Dynamic Phase Diagram
ChemPhysChem, 2015AbstractMetastability and phase coexistence are important concepts in colloidal science. Typically, the phase diagram of colloidal systems is considered at the equilibrium without the presence of an external field. However, several studies have reported phase transition under mechanical deformation.
