We are reporting a female case of semantic dementia. Characteristic of this type of dementia, she could not recognize some objects such as a pencil, a ruler or her dominant hand. When shown a pencil, she would ask “What is a pencil?” Her brain MRI showed atrophy of bilateral temporal lobes, especially anterior poles. SPECT also showed abnormally decreased blood flow in temporal lobes and fronta...

The pattern of silver nitrate (Ag)-staining differed among testicular lobes of Antiteuchus tripterus. In general, these differences are in regard to the number, size, shape, coloring intensity, and location of the stained bodies or masses, observed during meiosis and spermiogenesis. These characteristics were similar in lobes 1-3. Lobes 4-6, however, differed from each other and from lobes 1-3 ...

abstract horseshoe lung is a congenital pulmonary malformation that is usually associated with scimitar syndrome. this malformation consists of fusion of both pulmonary lobes from the posterobasal segments. the fusion appears in the retrocardiac area, in front of the esophagus and thoracic aorta. pleural separation of pulmonary lobes distinguishes pseudohorseshoe appearance from a true horsesho...

The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...

A new species of anisogammarid amphipod, Jesogammarus (Jesogammarus) ikiensis sp. n., is described from freshwaters in the Iki Island, Nagasaki Prefecture, Japan, based on results of morphological and molecular analyses. The new species is distinguished from all members of the genus by the combination of small number of setae on dorsal margins of pleonites 1-3, short and small number of setae o...

This paper investigates the channel allocation problem in multi-channel wireless networks with directional antennas. In particular, we propose a general analytical framework on the number of channels, in which we consider a new directional antenna model. This antenna model is more general than existing antenna models since other existing antenna models can be regarded as a special case of our m...
