Previous research has found that iconic gestures (i.e., gestures that depict the actions, motions or shapes of entities) identify referents that are also lexically specified in the co-occurring speech produced by proficient speakers. This study examines whether concrete deictic gestures (i.e., gestures that point to physical entities) bear a different kind of relation to speech, and whether thi...

This paper investigates bloatware bundling and product pricing decisions of a monopolistic firm when consumers can remove the bloatware from their electronic devices after purchase. We show conditions under which it is optimal for the firm not to bundle bloatware with their products. Furthermore, we show that even if the firm can make it harder for consumers to remove bloatware, the firm is not...

The Busse-Heikes dynamical model is described in terms of relaxational and nonre-laxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes l...

kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...

Infrared absorption of atomic and molecular vibrations in solids can be affected by electronic contributions through non-adiabatic interactions, such as the Fano effect. Typically, the infrared-absorption lineshapes are modified, or infrared-forbidden modes are detectable as a modulation of the electronic absorption. In contrast to such known phenomena, we report here the observation of a giant...

Chlorozotocin is a chloroethyl nitrosourea with a glucose carrier that has curative activity for the murine L1210 leukemia, but is nonmyelosuppressive in mice. To determine the mechanism for this unique property of reduced bone marrow toxicity, comparative studies were conducted with chlorozotocin and CCNU, a myelotoxic chloroethyl nitrosourea. Suspensions of L1210 leukemia and murine bone marr...

We have shown in a previous communication (1) that the enzyme triosephosphate dehydrogenase is rapidly inactivated in the presence of reduced diphosphopyridine nucleotide at physiological concentrations, temperature, and pH. Good stoichiometry was shown for the amount of enzyme inactivation, DPNH-X1 formation, and disappearance of sulfhydryl groups. It was then of particular interest to determi...

Recently, development of original technologies and connection technologies of UW-ASN for data transmission in underwater environment has been accelerated. Since propagation delay is inevitable at acoustic communication in underwater environment, the transmission time tends to be increased as network radius increases. Besides, there are difficulties of Multiple Access Control (MAC) service, whic...

To determine the physiological basis for the low glomerular filtration rate in chronic malnutrition, micropuncture studies were performed in Munich-Wistar rats chronically pair-fed isocaloric diets of either low (group 1, nine rats) or high protein content (group 2, nine rats). Despite the absence of hypoalbuminemia, average values for single nephron and total kidney glomerular filtration rate ...

The types of mobile robot can be roughly divided into three categories, wheeled type, crawler type and legged type. In these types, walking machine (legged type robot) has some of noteworthy strong points that other types of mobile robot don't have. Especially, high adaptability to the terrain is one of the most important strong points of walking machine. The fact that general type of walking m...
