At NTCIR-6 CLIR, Toshiba participated in the Monolingual and Bilingual IR tasks covering three topic languages (Japanese, English and Chinese) and one document language (Japanese). For Stage 1 (which is the usual ad hoc task using the new NTCIR6 topics), we submitted two DESCRIPTION runs and two TITLE runs for each topic language. Our first search strategy is Selective Sampling with Memory Rese...

In this paper, a multi-agent computational model is proposed to simulate the coevolution of social structure and compositional protolanguage from a holistic signaling system through iterative interactions within a heterogeneous population. We implement an indirect meaning transference based on both linguistic and nonlinguistic information in communications, together with a feedback without dire...

In the paper, a novel three-port channel drop filter in two dimensional photonic crystals (2D PCs) with a wavelength-selective reflection micro-cavity is proposed. In the structure, two micro-cavities are used. One is used for a resonant tunneling-based channel drop filter. The other is used to realize wavelength-selective reflection feedback in the bus wave-guide, which consists of a point def...

This research focused on how adult female brown-headed cowbirds, Molothrus ater, regulate social feedback on a group level to shape the development of male song. Specifically, females produce rapid wing movements in response to male song, termed ‘wing strokes,’ which have been shown to shape male song and predict song quality. These effects have been documented in captive dyads and triads, but ...

Recent work has characterized the sum capacity of time-varying/frequency-selective wireless interference networks and X networks within o(log(SNR)), i.e., with an accuracy approaching 100% at high SNR (signal to noise power ratio). In this paper, we seek similar capacity characterizations for wireless networks with relays, feedback, full duplex operation, and transmitter/receiver cooperation th...

The response to uniform selection may occur in alternate ways that result in similar performance. We tested for multiple adaptive solutions during artificial selection for high voluntary wheel running in laboratory mice. At generation 43, the four replicate high runner (HR) lines averaged 2.85-fold more revolutions per day as compared with four non-selected control (C) lines, and females ran 1....

Monolithically integrated four-channel distributed feedback (DFB) laser array has been fabricated by metal organic vapor phase epitaxy (MOVPE) selective area growth for 1.55μm coarsewavelength division multiplexing (CWDM) systems. Wide-stripe MOVPE selective area growth and electron-beam lithography are used to obtain wide CWDM channel spacing of 20 nm. Optical outputs from the simultaneously b...

This paper addresses the problem of channel equalization and tracking in turbo coded signals over frequency selective fading and delay spread channels. An innovative turbo equalization structure is presented jointly with the iterative decoding process, which is based on performing channel equalization via double decision feedback equalizer (DDFE) designed by using noncomplex least mean square a...

Introduction: Feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. This study aimed to assess the residents’ points of view about feedback in clinical education at Shiraz University of Medical Sciences.Methods: The sample of this study included 170 medical residents attending medical workshops in Shiraz University of ...
