inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...

introduction: a close link between spreading depression (sd) and several neurological diseases such as epilepsy could be demonstrated in many experimental studies. epilepsy is among the most common brain disorders. despite a large number of investigations, its mechanisms have not been yet well elucidated. hippocampus is one of the important structures involved in seizures. the aim of this study...

In this paper, we proved a rigidity theorem of the Hodge metric for concave horizontal slices and a local rigidity theorem for the monodromy representation.

It is important to understand the anatomical structures of the human brain in horizontal planes. Serially sectioned brain slices can easily be made with a meat slicer. The objective of this research was to enhance the educational value of serial brain slices made with a meat slicer through various applications. Two brains were taken out of two cadavers and embedded with gelatin solution to make...

The spread of epileptiform activity was monitored in guinea-pig neocortical slices by the use of a voltage-sensitive dye (RH795) and a fast optical recording technique. Epileptiform activity induced by bicuculline methiodide (10-20 microM) and single-pulse stimulation spread from the stimulation site in layer I or in the white matter across most of the slice. Different lesions were made in the ...

Introduction: Imaging with a reduced field of view (rFOV) is a way to reduce distortion in EPI by acquiring fewer phase-encode lines. However in cases in which regions of signal lie outside the phase field of view, aliasing will occur. This problem has been addressed by suppressing the volume outside the reduced field of view [1] and also by 2D selective excitation [2]. The latter is limited by...

Supragranular pyramidal neurons in the adult rat auditory cortex (AC) show marked long-term potentiation (LTP) of population spikes after tetanic white matter stimulation (TS). For determination of whether this marked LTP is specific to AC, LTP in rat AC slices was compared with LTP in slices of the visual cortex (VC). The amplitude of TS-induced LTP in AC was twice that in VC. LTP of EPSPs was...
