Scenarios for the Internet Migration of the Television Industry

All the conditions for the television industry’s migration to the Internet are now in place. While this migration will be gradual, it will have a deep-seated impact on the industry:•the exclusive rights model will no longer be the standard;•some consumers will abandon traditional managed networks;•a globalization trend will be sparked, to the benefit of the major rights holders. Unlike the music and print media industries, the TV industry is gaining a strong position on the Web. As a result, television is poised to play a central role in video services. This offensive strategy will likely pay off down the line, but does not entirely eliminate the possibility of destroying value. There are structural reasons for this, including a fiercely competitive online advertising market and a lack of control over program circulation. Far from being simply transitory, the 2009-2010 economic downturn marks the beginning of a decade of restructuring for the TV industry. This new period will begin with an overall decline in the sector’s resources before increasingly varied consumption patterns spur a new period of growth. The decade running from 2010 to 2020 will also be a period that focuses on cost control, with the industrialization of TV production that will depart once and for all from its historical model, i.e., film. This migration to the Web poses a threat to the European industry in particular. A reassessment of the television industry’s regulatory strategy appears both necessary and urgent, and will involve the creation of integrated pan-European conglomerates.Television, video, networks, on-demand, connected devices, advertising, pay-TV.

Insights gained from Total’s societal strategy: from local acceptability to shared value

Since 2000 Total has been developing local acceptability procedures in its subsidiaries and at its sites that comprise four main components: dialogue with local stakeholders, controlling the impacts of industrial activities, optimizing the contribution to the sustainable social and economic development of communities and territories where the Group operates and being recognized as a prime mover regarding access to energy. Now well established (with dedicated human resources, tools and methodologies), this societal strategy is facing several challenges that need to be met if the Group is to continue to achieve operational excellence and longevity

The Ecce and Logen Partial Evaluators and their Web Interfaces

We present Ecce and Logen, two partial evaluators for Prolog using the online and offline approach respectively. We briefly present the foundations of these tools and discuss various applications. We also present new implementations of these tools, carried out in Ciao Prolog. In addition to a command-line interface new user-friendly web interfaces were developed. These enable non-expert users to specialise logic programs using a web browser, without the need for a local installation

The ostium primum or partial atrioventricular septal defect

peer reviewedaudience: researcher, professional, studentOften assimilated to simple inter-atrial communication, the ostium primum, or partial atrio-ventricular septal defect, is an entity that is characterized by a different embryological mechanism and requires some specific surgical expertise. Basically, knowledge of the morphology of the common atrioventricular valve with 5 components, the topography of the A-V node and His bundle, and the ventricular consequences of the absence of atrio-ventricular septal structures must be taken into account

Reducing CO2 to methanol using frustrated Lewis pairs : on the mechanism of phosphine-borane mediated hydroboration of CO2

The full mechanism of the hydroboration of CO2 by the highly active ambiphilic organocatalyst 1-Bcat-2-PPh2-C6H4 (Bcat = catecholboryl) was determined using computational and experimental methods. The intramolecular Lewis pair was shown to be involved in every step of the stepwise reduction. In contrast to traditional frustrated Lewis pair systems, the lack of steric hindrance around the Lewis basic fragment allows activation of the reducing agent while moderate Lewis acidity/basicity at the active centers promotes catalysis by releasing the reduction products. Simultaneous activation of both the reducing agent and carbon dioxide is the key to efficient catalysis in every reduction step

CM cycles on Shimura curves, and p-adic L-functions

Let f be a modular form of weight k>=2 and level N, let K be a quadratic imaginary field, and assume that there is a prime p exactly dividing N. Under certain arithmetic conditions on the level and the field K, one can attach to this data a p-adic L-function L_p(f,K,s), as done by Bertolini-Darmon-Iovita-Spiess. In the case of p being inert in K, this analytic function of a p-adic variable s vanishes in the critical range s=1,...,k-1, and therefore one is interested in the values of its derivative in this range. We construct, for k>=4, a Chow motive endowed with a distinguished collection of algebraic cycles which encode these values, via the p-adic Abel-Jacobi map. Our main result generalizes the result obtained by Iovita-Spiess, which gives a similar formula for the central value s=k/2. Even in this case our construction is different from the one found by Iovita-Spiess

Metal-free catalytic C-H bond activation and borylation of heteroarenes

Transition metal complexes are efficient catalysts for the C-H bond functionalization of heteroarenes to generate useful products for the pharmaceutical and agricultural industries. However, the costly need to remove potentially toxic trace metals from the end products has prompted great interest in developing metal-free catalysts that can mimic metallic systems. We demonstrated that the borane (1-TMP-2-BH2-C6H4)2 (TMP, 2,2,6,6-tetramethylpiperidine) can activate the C-H bonds of heteroarenes and catalyze the borylation of furans, pyrroles, and electron-rich thiophenes. The selectivities complement those observed with most transition metal catalysts reported for this transformation

A highly active phosphine-borane organocatalyst for the reduction of CO2 to methanol using hydroboranes

In this work, we report that organocatalyst 1-Bcat-2-PPh2-C6H4 ((1); cat = catechol) acts as an ambiphilic metal-free system for the reduction of carbon dioxide in presence of hydroboranes (HBR2 = HBcat (catecholborane), HBpin (pinacolborane), 9-BBN (9-borabicyclo[3.3.1]nonane), BH3·SMe2 and BH3·THF) to generate CH3OBR2 or (CH3OBO)3, products that can be readily hydrolyzed to methanol. The yields can be as high as 99% with exclusive formation of CH3OBR2 or (CH3OBO)3 with TON (turnover numbers) and TOF (turnover frequencies) reaching >2950 and 853 h(-1), respectively. Furthermore, the catalyst exhibits "living" behavior: once the first loading is consumed, it resumes its activity on adding another loading of reagents
