Parametric estimation of signals, based on quantized data, is often carried out by means of least squares (LS) or averaging techniques. Such an approach often leads to optimal performance, resulting in almost unbiased estimators when the quantization error can approximately be modeled as an additive white Gaussian noise, or when other additive white Gaussian noise sources are larger than the qu...

The clinical evidences of variable epileptic propagation in occipital lobe epilepsy (OLE) have been demonstrated by several studies. However the exact localization of the epileptic focus sometimes represents a problem because of the rapid propagation to frontal, parietal, or temporal regions. Each white matter pathway close to the supposed initial focus can lead the propagation towards a specif...

Discussions regarding the correlations between elevated white blood cell levels and clinical and pathological stages of acute appendicitis are well known. Recent studies show that a high level of serum bilirubin could emerge as a prognostic marker for gangrenous or perforated stages of acute appendicitis. We studied the correlations between anatomical and pathological stages of acute appendicit...

BACKGROUND Apathy is a common and problematic symptom of several neurodegenerative illnesses, but its neuroanatomical bases are not understood. OBJECTIVE To determine the regions associated with apathy in subjects with mild Alzheimer's disease (AD) using a method that accounts for the significant co-linearity of regional atrophy and neuropsychiatric symptoms. METHODS We identified 57 subjec...

Synonyms of first metatarsal brachymetatarsia include metatarsus primus atavicus, metatarsus primus brevis, metatarsus primus brevis varus syndrome, pied ancestral (French), pied de Neanderthal (French), short first metatarsal syndrome and Morton's syndrome (Dudley Joy Morton). Brachymetatarsia is a condition in which the metatarsal physis closes prematurely yielding a pathologically shortened ...

this article reviews clinically relevant data regarding punctate inner choroidopathy, mainly the various treatment options. punctate inner choroidopathy is an uncommon, inflammatory, multifocal chorioretinopathy affecting mostly young myopic women. it is characterized by the presence of multiple, small, well-defined, yellow-white fundus lesions, in the absence of intraocular inflammation. we de...

A centerpiece of Dynamical Systems is comparison by an equivalence relationship called topological conjugacy. Current state of the field is that, generally, there is no easy way to determine if two systems are conjugate or to explicitly find the conjugacy between systems that are known to be equivalent. We present a new and highly generalizable method to produce conjugacy functions based on a f...
