Integrated scheme of rapid environmental assessment for shallow water acoustics

Predicting sound propagation in shallow or very shallow water environments requires that the frequency-dependent acoustic properties be assessed for all components of the waveguide, i.e., the water column, sea bottom and sea surface interface. During the Maritime Rapid Environmental Assessment MREA?BP'07 sea trial in April-May 2007, south of Elba Island in the Mediterranean Sea, an integrated MREA scheme has been implemented to provide a full 4D (3D+T) environmental picture that is directly exploitable by acoustic propagation models. Based on a joint multi-disciplinary effort, several standard and advanced techniques of environmental characterization covering the fields of underwater acoustics, physical oceanography and geophysics have been combined within a coherent scheme of data acquisition, processing and assimilation. The paper presents the whole architecture of the implemented scheme. Based on a preliminary analysis of MREA?BP'07 data, advantages and drawbacks of the approach will be discussed. Ways ahead for further improvement and perspectives are finally drawn

Problematic Cannabis Use and Risk of Complications in Patients with Chronic Hepatitis C

Objectives To evaluate the risk of complication in hospitalized chronic hepatitis C (CHC), patients with cannabis use disorder (CUD). Methods We conducted a retrospective study using the nationwide inpatient sample (NIS), and included 31,623 patients (age 15-54) with a primary international classification of diseases, ninth revision (ICD-9) diagnosis for CHC and grouped by co-diagnosis of CUD (1101, 3.5%). Logistic regression model adjusted for confounders was used to evaluate the odds ratio (OR) of CUD and complications during CHC hospitalization. Results Comorbid CUD was prevalent in males (73.2%), Caucasians (59.9%), and from low-income families (65.7%). The most prevalent complications in patients with CUD were ascites (44.9%), alcoholic cirrhosis (42.8%) and non-alcoholic cirrhosis (41.1%). The odds of association for hepatic encephalopathy was 2.2 times higher (95% CI 1.477-3.350) in 2.8% CHC inpatients with CUD compared to 1.2% non-CUD inpatients. Hepatic encephalopathy had higher odds of association with a male by 1.4 times (95% CI 1.094-1.760), and African American by 1.7 times (95% CI 1.293-2.259). Conclusion CUD is significantly associated with 122% increased likelihood for hepatic encephalopathy that may worsen overall hospitalization outcomes in CHC patients. Hence, we need to consider the complex relationship between CUD and CHC and manage them optimally to improve the health-related quality of life

Le sacre du paysage tibétain

Dans les années 1910, les explorations au Tibet connaissent un succès sans précédent. À l’écart des enjeux impérialistes britanniques, les voyageurs français proposent une vision non unifiée du Tibet. Toutefois, la récurrence d’une dimension sacrée prêtée au paysage tibétain dans leurs différents récits, anglais comme français, surprend le lecteur. Dans le contexte du « Grand Jeu », les voyageurs britanniques conçoivent avant tout le Tibet comme un « État-tampon » au-delà de l’Inde. Associée à une problématique géopolitique, la dimension sacrée conférée au Tibet tient d’un geste apotropaïque. Ce sont d’autres connotations que l’on peut lire dans la sacralité du paysage tibétain chez les voyageurs français. Fernand Grenard (Le Tibet. Le pays et les habitants, 1910) considère les montagnes sacrées du Tibet comme la manifestation de « l’âme bouddhique ». Pour Jacques Bacot, dans Le Tibet révolté (1912), le paysage sacré est le creuset d’une réflexion sur les représentations collectives où sa rencontre avec des Tibétains joue un rôle de premier plan. À l’intersection des traditions anglaises et françaises, Alexandra David-Néel opère une synthèse des représentations antérieures dont la fortune court jusqu’à aujourd’hui : Tibet imaginé et Tibet vécu sont ici dissociés (Journal de voyage, lettres de 1912). Ainsi, en quelques années, sont proposées aux lecteurs européens des expériences et des images du Tibet fort variables dont, dans l’histoire globale des représentations du Tibet, on ne peut limiter les horizons à ceux, perdus, du célèbre Shangri-La.Explorations of Tibet reach a so far unmatched peak around 1910. French travelers to Tibet give us heterogeneous representations of this country that differ in many ways from those of British explorers, which involve imperialist issues. While British and French explorers alike describe the country in terms of “sacred landscape,” their underlying motivation to do so is distinct. In the context of the Great Game, British travelers consider Tibet as a “buffer state” beyond the British Rāj of India: ascribing a sacred character to Tibet amounts to attribute it a protective power over the imperial territory. In contrast, the French traveler Fernand Grenard (Tibet. The Country and Its Inhabitants, 1910) envisions the sacred mountains of Tibet as the symbol of Buddhist spirituality, and in his Tibet In Revolt (1912), Jacques Bacot’s prime interest is to understand how the Tibetans themselves view the sacred character of landscape. At the crossroad of the British and French traditions, the well known adventurer Alexandra David-Néel carries out in her travel diary of 1912 a synthesis of previous representations, and distinguishes the imagined Tibet from the real Tibet. In these years, the European reader is exposed to a variety of experiences and images. From the perspective of a global history of representations of Tibet, one thus cannot limit the Tibetan horizon to the lost horizons of Shangri-La

Impact of Camera and Lighting Position on Video Detection Precision

On well-illuminated approaches, vehicle headlight reflections on the pavement were observed to cause video detection units to activate early. This early activation results in a dramatic increase in the length of the effective vehicle detection zone. This observed variation in the effective length of the vehicle detection zone that varies by ambient lighting condition and camera placement presents a very serious impediment for traffic engineers to design vehicle extension intervals that operate correctly during day, night and transition periods. Furthermore, the stochastic variation in the length of the vehicle detection zone length has the potential to create driver expectancy issues. Tables are included that reports the observed average and range of detection zone length variations for 16 observed video cameras that were extensively calibrated by the manufacturer at the test site. The paper concludes by recommending near-side placement of video detection devices to reduce the stochastic variation in detection zone length
