A case of solitary rectal ulcer syndrome in a 36-year-old woman presenting with severe, persistent mucorrhea and eroded polypoid hyperplasia as the predominant clinical features, who was ultimately noted to have symptoms of rectal prolapse, is presented. Endoscopically, she had multiple (50 to 60) small, whitish polypoid lesions in the rectum that were initially misinterpreted as...

Microdialysis and ultrasound elastography for monitoring of localized muscular reaction after pharmacological stimulation in rats

ObjectiveHalothane and caffeine are known to cause skeletal muscular contractions in vitro and have been proven to induce circumscribed metabolic reactions when injected into rat skeletal muscle. In this study 26 rats were investigated by either continuous application of calcium 160 mM or bolus injection of caffeine 160 mM or halothane 10% vol via a microdialysis probe in the...

Probability Model for Data Redundancy Detection in Sensor Networks

Sensor networks are made of autonomous devices that are able to collect, store, process and share data with other devices. Large sensor networks are often redundant in the sense that the measurements of some nodes can be substituted by other nodes with a certain degree of confidence. This spatial correlation results in wastage of link bandwidth and energy. In this paper, a model...

Dissociative Disturbance in Hangul-Hanja Reading after a Left Posterior Occipital Lesion

Since the Korean language has two distinct writing systems, phonogram (Hangul) and ideogram (Hanja: Chinese characters), alexia can present with dissociative disturbances in reading between the two systems. A 74-year-old right-handed man presented with a prominent reading impairment in Hangul with agraphia of both Hangul and Hanja after a left posterior occipital- parietal lesion...

Bulging Modes of Circular Bottom Plates in Rigid Cylindrical Containers Filled with a Liquid

In this article the free vibrations of the bottom plate of an otherwise rigid circular cylindrical tank filled with liquid are studied, considering only the bulging modes (when the amplitude of the plate displacement is predominant with respect to that of the free surface). The tank axis is vertical, thus the free liquid surface is orthogonal to the tank axis. The liquid is...

The nonexistence of rank 4 IP tensors in signature (1,3)

Let V be a real vector space of dimension 4 with a nondegenerate symmetric bilinear form of signature (1,3). We show that there exists no algebraic curvature tensor R on V so that its associated skew-symmetric operator R(⋅) has rank 4 and constant eigenvalues on the Grassmannian of nondegenerate 2-planes in V.

Reduction of differentiable equations with impulse effect

We consider a problem of a partial linearization of noninvertible differential equations with impulse effect and establish sufficient conditions for the dynamical equivalence.
