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...

We developed a new apparatus and psychophysical technique to extend isoluminant contrast-sensitivity measurements to high spatial frequencies. The apparatus consists of two identical laser interferometers that are designed to produce phase-locked two-color interference fringes on the retina without the influence of diffraction and most aberrations in the eye. However, even with interferometry, ...

The sampling and interpolation of a sound field in two and three dimensions along a circle is discussed. The Fourier domain representation of the sound field is used, and an angular sampling theorem is developed for the sampling of the sound field along a circle. Based on these results, HRTF sampling and interpolation are discussed. This method achieves very precise interpolation in terms of me...

In this paper, we are discussing the sampling and interpolation of the sound field in two and three dimensions along a circle. The Fourier domain representation of the sound field is used and an angular sampling theorem is developed for the sampling of the sound field along a circle. Based on these results, HRTF sampling and interpolation are discussed. As recently presented in [2], HRTF interp...

the optimal fractionation schedule for radiotherapy of head and neck cancer has been controversial. the objective of this randomized trial was to test the efficacy of hyperfractionation vs. standard fractionation. patients with squamous cell carcinoma of head and neck organs were randomly assigned to receive radiotherapy delivered with a) standard fractionation at 2 gy/fraction/day, 5 days/week...

granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

PURPOSE The purpose of this survey were to assess the dental caries prevalence rate among children enrolled in Ohio's Head Start programs and assess factors relating to their dental care access. METHODS Oral screenings were conducted on 2,555 children, ages 3 through 5 years, at 50 Ohio Head Start centers using probability-proportional-to-size sampling. In addition, parental responses to 6 ac...

we conducted a study to evaluate efficacy and safety of dimeticone 4%, a lotion with no conventional insecticide activity, to cure lice infection and to prevent spread of infestation/reinfestation by prophylaxis of classmates.the study is carried out between april 2008 and june 2008 in petranova international institute in rome. a total of 131 children, aged 3 to 13 years (median age: 7 years) w...

BACKGROUND Soccer is a contact sport in which the players are frequently faced with the risk of injury. It has been shown that the force exerted on the head during heading can be as much as 500-1200 Newton (N). OBJECTIVES The main objective of this study was to determine whether there was any relationship between the force exerted on the head and several biomechanical and anthropometrical par...

A theory and a system for capturing an audio scene and then rendering it remotely are developed and presented. The sound capture is performed with a spherical microphone array. The sound field at the location of the array is deduced from the captured sound and is represented using either spherical wave-functions or plane-wave expansions. The sound field representation is then transmitted to a r...
