Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

The Greisen Equation Explained and Improved [PDF]

, 2006
Analytic description of the evolution of cosmic ray showers is dominated by the Greisen equation nearly five decades old. We present an alternative approach with several advantages. Among the new features are a prediction of the differential distribution,

The influence of university entrance examinations on teaching of the definite integral at High School

Enseñanza de las Ciencias, 2011
The definite integral is considered a main topic in High School mathematics. An empirical evidence of this fact is the frequent use of it in the inclusion of a question, exercise or problem involving this mathematical notion in the university entrance ...

Percolation model for nodal domains of chaotic wave functions

, 2001
Nodal domains are regions where a function has definite sign. In recent paper [nlin.CD/0109029] it is conjectured that the distribution of nodal domains for quantum eigenfunctions of chaotic systems is universal.

On Quantum Jumps, Events and Spontaneous Localization Models [PDF]

, 1994
We propose a definite meaning to the concepts of "experiment", "measurement" and "event" in the event-enhanced formalism of quantum theory. A minimal piecewise deterministic process is given that can be used for a computer simulation of real time series ...

Minimally Clinically Important Difference of the Clinical Assessment Scale in Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The Clinical Assessment Scale in Autoimmune Encephalitis (CASE) tracks disease severity in autoimmune encephalitis (AE), but no threshold for significant change exists. We aimed to determine the minimally clinically important difference (MCID) for CASE.
