A survey of entomogenous fungi was undertaken in the reserve of Wawu Mountains, Sichuan, China in July 1997. The specimens of the genus Cordyceps and other entomogenous fungi collected included C. militaris (Vuill.) Fr., C. agriota Kawam, C. nutans Pat., C. tricentri Yasuda, C. sphecocephala (K1.) Sacc., Paecilomyces cacadae (Miquel) Samson, Paecilomyces farinosus (Wize) Brown & Smith, Beauveri...

This paper presents a study on the recognition of the visual focus of attention (VFOA) of meeting participants based on their head pose. Contrarily to previous studies on the topic, in our set-up, the potential VFOA of people is not restricted to other meeting participants only, but includes environmental targets (table, slide screen). This has two consequences. Firstly, this increases the numb...

BACKGROUND Air-borne bacteria in the operating room (OR) may contaminate the surgical wound, either by direct sedimentation from the air or indirectly, by contaminated sterile instruments. Reduced air contamination can be achieved with an efficient ventilation system. The current study assesses the additive effect of a mobile laminar airflow (MLAF) unit on the microbiological air quality in an ...

In this paper, we propose a visual saliency algorithm for automatically finding the topic transition points in an educational video. First, we propose a method for assigning a saliency score to each word extracted from an educational video. We design several mid-level features that are indicative of visual saliency. The optimal feature combination strategy is learnt from a Rank-SVM to obtain an...

The paper presents an evaluation of both head pose and visual focus of attention (VFOA) estimation algorithms in a meeting room environment. Head orientation is estimated using a Rao-Blackwellized mixed state particle filter to achieve joint head localization and pose estimation. The output of this tracker is exploited in an Hidden Markov Model (HMM) to estimate people’s VFOA. Contrarily to pre...

Much progress has been made over four decades in developing, testing, and evaluating the performance of mathematical models for predicting pollutant concentrations from smoking in indoor settings. Although largely overlooked by the regulatory community, these models provide regulators and risk assessors with practical tools for quantitatively estimating the exposure level that people receive in...

AIMS To evaluate the microbiological efficacy of a down-draught necropsy table ventilation system (which surrounds the cadaver with a "curtain" of air under continuous extraction) during post mortem procedures. METHODS Air sampling was carried out both in the presence and absence of staff and cadaver and during a full post mortem procedure, with functioning and non-functioning table air extra...
