The literature has pointed out the negative aspects of political dynasties. But can political dynasties help prevent autocratic reversals? We argue that political dynasties differ according to their ideological origin and that those whose founder was a defender of democratic ideals, for simplicity labeled “pro-democratic dynasties,” show stronger support for democracy. We analyze the vote by the French parliament on 10 July 1940 of an enabling act that granted full power to Marshall Philippe Pétain, thereby ending the Third French Republic and aligning France with Nazi Germany. Using data collected from the biographies of parliamentarians and information on their voting behavior, we find that members of a pro-democratic dynasty were 9.6 to 15.1 percentage points more likely to oppose the act than other parliamentarians. We report evidence that socialization inside and outside parliament shaped the vote of parliamentarians.

The thermal transport in amorphous/crystalline silicon superlattices with means of molecular dynamics is presented in the current study. The procedure used to build such structures is discussed. Then, thermal conductivity of various samples is studied as a function of the periodicity of regular superlattices and of the applied temperature. Preliminarily results show that for regular amorphous/crystalline superlattices, the amorphous regions control the heat transfer within the structures. Secondly, in the studied cases thermal conductivity weakly varies with the temperature. This, points out the presence of a majority of non-propagating vibrational modes in such systems.

Endothelial dysfunction is a turning point in the initiation and development of atherosclerosis and its complications and is predictive of future cardiovascular events. Ingestion of high-carbohydrate or high-fat meals often results in postprandial hyperglycaemia and/or hypertriacylglycerolaemia that may lead to a transient impairment in endothelial function. The present review will discuss human studies evaluating the impact of high-carbohydrate and high-fat challenges on postprandial endothelial function as well as the potential role of oxidative stress in such postprandial metabolic alterations. Moreover, the present review will differentiate the postprandial endothelial and oxidative impact of meals rich in varying fatty acid types.

The Gulf of St. Lawrence aster, Symphyotrichum laurentianum (Fernald) G.L. Nesom (Asteraceae), a small annual halophyte endemic to disturbed and highly transient habitats in the Gulf of St. Lawrence, is classified as “threatened” by the Committee on the Status of Endangered Wildlife in Canada. Lepidopteran larvae that are predispersal seed predators of the Gulf of St. Lawrence aster are reported for the first time from populations in Prince Edward Island National Park. DNA barcoding was used to identify the seed predators tentatively as larvae of the casebearing moth Coleophora triplicis McDunnough (Lepidoptera: Coleophoridae), which is typically associated with a related halophyte, Solidago sempervirens L. (Asteraceae). These larvae were found to consume a large proportion of seeds from one of two aster populations in Prince Edward Island National Park and may be yet another risk to the survival of this threatened species.

We propose a numerical solution to incorporate in the simulation of a system of conservation laws boundary conditions that come from a microscopic modeling in the small mean free path regime. The typical example we discuss is the derivation of the Euler system from the BGK equation. The boundary condition relies on the analysis of boundary layers formation that accounts from the fact that the incoming kinetic flux might be far from the thermodynamic equilibrium.

Up to now, no case of spontaneous sex reversal has been described in the urodele amphibian Pleurodeles waltl reared at ambient temperature. However in offspring reared under laboratory conditions, males, females but also intersex individuals were obtained. The males, some females and the intersexes had the ZZ male genotype identified through a test performed with a sex-linked enzyme. The other females had the ZW female genotype. Using the animals of this particular strain, an offspring analysis was made on crosses between, respectively, ZZ males and ZW females, ZZ males and ZZ females, and ZZ intersexes and ZZ males or females. All these crosses gave ZZ males, ZZ females and ZZ intersexes. The spontaneous complete or partial sex reversal is inheritable, but the genetic mechanism of this inheritance has not yet been elucidated.
