TL;DR: In this article, the α,ω-bis (4n-alkylanilinebenzylidine-4′-oxy)alkanes have been synthesized and their transitional properties characterized.
Abstract: Eleven series of dimeric liquid crystals, namely the α,ω-bis(4-n-alkylanilinebenzylidine-4′-oxy)alkanes, have been synthesized and their transitional properties characterized. The number of methylene groups in the flexible core was varied from one to twelve while the length of the terminal alkyl chains was increased from a methyl group to a decyl substituent. The rich smectic polymorphism of this family of compounds was studied using X-ray diffraction and polarizing microscopy; it includes several examples of rare phase transitions, for example, smectic F-smectic A and crystal G-isotropic, as well as novel modulated hexatic phases based on a two dimensional lattice. The transitional properties of a given series, where the length of the terminal chain is held constant while the length and parity of the flexible spacer is varied, exhibit a pronounced alternation. For example, the entropy change at the nematic-isotropic transition exhibits a strong alternation and this has been interpreted in terms ...

TL;DR: Experienced laparoscopic surgeons performed the tasks significantly faster, with less error, more economy in the movement of instruments and the use of diathermy, and with greater consistency in performance, showing high internal measurement consistency.
Abstract: Background: The objective assessment of the psychomotor skills of surgeons is now a priority; however, this is a difficult task because of measurement difficulties associated with the assessment of surgery in vivo. In this study, virtual reality (VR) was used to overcome these problems. Methods: Twelve experienced (>50 minimal-access procedures), 12 inexperienced laparoscopic surgeons (<10 minimal-access procedures), and 12 laparoscopic novices participated in the study. Each subject completed 10 trials on the Minimally Invasive Surgical Trainer; Virtual Reality (MIST VR). Results: Experienced laparoscopic surgeons performed the tasks significantly (p < 0.01) faster, with less error, more economy in the movement of instruments and the use of diathermy, and with greater consistency in performance. The standardized coefficient alpha for performance measures ranged from a = 0.89 to 0.98, showing high internal measurement consistency. Test–retest reliability ranged from r = 0.96 to r = 0.5. Conclusion: VR is a useful tool for evaluating the psychomotor skills needed to perform laparoscopic surgery.

TL;DR: It is considered that support of patients with chronic cough was inadequate and the Task Force recommends that further work is urgently required in this neglected area.
Abstract: In 2011, a European Respiratory Society Task Force embarked on a process to determine the position and clinical relevance of the cough hypersensitivity syndrome, a disorder characterised by troublesome coughing often triggered by low levels of thermal, mechanical or chemical exposure, in the management of patients with chronic cough. A 21-component questionnaire was developed by an iterative process supported by a literature review. 44 key opinion leaders in respiratory medicine were selected and interviewed as to their opinions.
There was a high degree of unanimity in the responses obtained, with all opinion leaders supporting the concept of cough hypersensitivity as a clinically useful paradigm. The classic stratification of cough into asthmatic, rhinitic and reflux-related phenotypes was supported. Significant disparity of opinion was seen in the response to two questions concerning the therapy of chronic cough. First, the role of acid suppression in reflux cough was questioned. Secondly, the opinion leaders were split as to whether a trial of oral steroids was indicated to establish a diagnosis of eosinophilic cough.
The cough hypersensitivity syndrome was clearly endorsed by the opinion leaders as a valid and useful concept. They considered that support of patients with chronic cough was inadequate and the Task Force recommends that further work is urgently required in this neglected area.

TL;DR: The challenge guidelines, the common data used, and the performance of the baseline system on the two tasks are presented.
Abstract: We present the second Audio-Visual Emotion recognition Challenge and workshop (AVEC 2012), which aims to bring together researchers from the audio and video analysis communities around the topic of emotion recognition. The goal of the challenge is to recognise four continuously valued affective dimensions: arousal, expectancy, power, and valence. There are two sub-challenges: in the Fully Continuous Sub-Challenge participants have to predict the values of the four dimensions at every moment during the recordings, while for the Word-Level Sub-Challenge a single prediction has to be given per word uttered by the user. This paper presents the challenge guidelines, the common data used, and the performance of the baseline system on the two tasks.
