Though increasing usage of just-in-time (JIT) practices is reported, academics—including Shapiro at Harvard Business School, Karmarkar at UCLA (Anderson) and Cusumano at MIT (Sloan)—as well as a number of practitioners have warned against the unrestricted pursuit of just-in-time practices. They suggest that pure JIT is appropriate only for limited economic environments, that it is ineffective i...

We prove that n cops can capture (that is, some cop can get less than unit distance from) a robber in a continuous square region with side length less than √ 5n and hence that bn/ √ 5c+ 1 cops can capture a robber in a square with side length n. We extend these results to three dimensions, proving that 0.34869 · · ·n2 +O(n) cops can capture a robber in a n× n× n cube and that a robber can forev...

We have investigated the phase diagram of a statistical model for hydrogen-bonding solutions for polar solutes. The structured solvent is represented by an associating lattice gas, which presents anomalous density and liquid-liquid coexistence. Polar solute particles and solvent particles interact attractively, while the solvent-solvent interaction is made directional through bonding arms, whic...

Outline shapes were moved back and forth at .5 Hz behind a simulated narrow (10' or 15') slit without visible borders. Under free-viewing conditions observers reported spontaneous transitions between periods in which they saw a horizontally moving shape and periods in which they saw only vertically moving contour segments. Eye movements were monitored with a dual-Purkinje image eye-tracker. On ...

This study aimed to objectivize the quality of smooth pursuit eye movements in a standard laboratory task before and after an Eye Movement Desensitization and Reprocessing (EMDR) session run on seven healthy volunteers. EMDR was applied on autobiographic worries causing moderate distress. The EMDR session was complete in 5 out of the 7 cases; distress measured by SUDS (Subjective Units of Disco...

The contribution of the flocculus region of the cerebellum to horizontal gaze pursuit was studied in squirrel monkeys. When the head was free to move, the monkeys pursued targets with a combination of smooth eye and head movements; with the majority of the gaze velocity produced by smooth tracking head movements. In the accompanying study we reported that the flocculus region was necessary for ...

Since the semiconductor industry based on Si is approaching limit of performance improvement, it is a persisting pursuit to use metal as channel material in a fi eld effect transistor (FET). All-metallic FETs could be scaled down to smaller size with less energy consume and performance at higher frequency. [ 1 ] No metal or semimetal has shown any notable fi eld effect until the appearance of g...

When a visual stimulus changes direction and distance simultaneously, Hering's Law argues that the resulting eye movements are the result of combined version and vergence control processes. Recently, it has been suggested that slow asymmetrical eye movements might be guided by monocular control processes wherein each eye is driven by its own retinal image. Experimental results presented here sh...

A number of studies have shown that stationary backgrounds compromise smooth pursuit eye movements. It has been suggested that poor attentional selection of the pursuit target was responsible for reductions of pursuit gain. To quantify the detrimental effects of attention, we instructed observers to either pay attention to background objects or to ignore them. The to-be-attended object was indi...
