Nutritional state, i.e. fasting or non-fasting, may affect the processing of interoceptive signals, but mechanisms underlying this effect remain unclear. We investigated 16 healthy women on two separate days: when satiated (standardized food intake) and after an 18 h food deprivation period. On both days, heartbeat-evoked potentials (HEPs) and cardiac and ANS activation indices (heart rate, nLF HRV) were assessed. The HEP is an EEG pattern that is considered an index of cortical representation of afferent cardiovascular signals. Average HEP activity (R-wave +455-595 ms) was enhanced during food deprivation compared to normal food intake. Cardiac activation did not differ between nutritional conditions. Our results indicate that short-term food deprivation amplifies an electrophysiological correlate of the cortical representation of visceral-afferent signals originating from the cardiovascular system. This effect could not be attributed to increased cardiac activation, as estimated by heart rate and nLF HRV, after food deprivation. [less ▲]

We present regression automata (RA), which are novel type syntactic models for time series forecasting. Building on top of conventional state-merging algorithms for identifying automata, RA use numeric data in addition to symbolic values and make predictions based on this data in a regression fashion. We apply our model to the problem of hourly wind speed and wind power forecasting. Our results show that RA outperform other state-of-the-art approaches for predicting both wind speed and power generation. In both cases, short-term predictions are used for resource allocation and infrastructure load balancing. For those critical tasks, the ability to inspect and interpret the generative model RA provide is an additional benefit. [less ▲]

A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driving to open quantum processes. Shortcuts to adiabaticity designed in this fashion can be implemented in two alternative physical scenarios: one characterized by the pres- ence of balanced gain and loss, the other involves non-Markovian dynamics with time-dependent Lindblad operators. As an illustration, we engineer superadiabatic cooling, heating, and isothermal strokes for a two-level system, and provide a pro- tocol for the fast thermalization of a quantum oscillator. [less ▲]

Squeezed state in harmonic systems can be generated through a variety of techniques, including varying the oscillator frequency or using nonlinear two-photon Raman interaction. We focus on these two techniques to drive an initial thermal state into a final squeezed thermal state with controlled squeezing parameters—amplitude and phase—in arbitrary time. The protocols are designed through reverse engineering for both unitary and open dynamics. Control of the dissipation is achieved using stochastic processes, readily implementable via, e.g., continuous quantum measurements. Importantly, this allows controlling the state entropy and can be used for fast thermalization. The developed protocols are thus suited to generate squeezed thermal states at controlled temperature in arbitrary time. [less ▲]

Using data from the European Community Household Panel, this paper evaluates the impact of the exogenous reductions in weekly working hours induced by reforms implemented in Portugal and France on worker wellbeing. Difference-in-differences estimation results suggest that reduced working hours generated significant and robust increases in job and leisure satisfaction of the workers affected in both countries (from 0.07 to 0.15 standard deviation increases), with the rise in the former mainly being explained by greater satisfaction with working hours and working conditions. Further results suggest that staff representative bodies are important for ensuring that working-time reductions lead to welfare gains. [less ▲]

Empirical validations of research approaches eventually require a curated ground truth. In studies related to Android malware, such a ground truth is built by leveraging Anti-Virus (AV) scanning reports which are often provided free through online services such as VirusTotal. Unfortunately, these reports do not offer precise information for appropriately and uniquely assigning classes to samples in app datasets: AV engines indeed do not have a consensus on specifying information in labels. Furthermore, labels often mix information related to families, types, etc. In particular, the notion of “adware” is currently blurry when it comes to maliciousness. There is thus a need to thoroughly investigate cases where adware samples can actually be associated with malware (e.g., because they are tagged as adware but could be considered as malware as well). In this work, we present a large-scale analytical study of Android adware samples to quantify to what extent “adware should be considered as malware”. Our analysis is based on the Androzoo repository of 5 million apps with associated AV labels and leverages a state-of-the-art label harmonization tool to infer the malicious type of apps before confronting it against the ad families that each adware app is associated with. We found that all adware families include samples that are actually known to implement specific malicious behavior types. Up to 50% of samples in an ad family could be flagged as malicious. Overall the study demonstrates that adware is not necessarily benign. [less ▲]

Interleukin-6 (IL-6) activates the Jak/STAT pathway as well as the mitogen-activated protein kinase cascade. Tyrosine 759 of the IL-6 signal-transducing receptor subunit gp130 has been identified as being involved in negative regulation of IL-6-induced gene induction and activation of the Jak/STAT pathway. Because this site is known to be a recruitment motif for the protein-tyrosine phosphatase SHP2, it has been suggested that SHP2 is the mediator of tyrosine 759-dependent signal attenuation. We recently observed that the suppressor of cytokine-signaling SOCS3 also acts through the tyrosine motif 759 of gp130. However, the relative contributions of SHP2 and SOCS3 to the repression of IL-6 signaling are not understood. Therefore, we designed experiments allowing the independent recruitment of each of these proteins to the IL-6-receptor complex. We show that receptor- and membrane-targeted SHP2 counteracts IL-6 signaling independent of SOCS3 binding to gp130. On the other hand, SOCS3 inhibits signaling in cells expressing a truncated SHP2 protein, which is not recruited to gp130. These data suggest, that there are two, largely distinct modes of negative regulation of gp130 activity, despite the fact that both SOCS3 and SHP2 are recruited to the same site within gp130.

Au mois d’août 1830, la Revue de Paris publie les poèmes inédits d’un certain Auguste Barbier, alors âgé de vingt-cinq ans. Rencontrant un succès immédiat, ces pièces satiriques inspirées par la révolution de Juillet sont bientôt rassemblées en recueil sous un titre emprunté à Chénier – les Iambes. Ni classique, ni romantique, le jeune poète échappe à toute tentative de catégorisation ; seule demeure, inébranlable, sa foi en les principes républicains. Révolté par la façon dont Louis-Philippe a récupéré les Trois Glorieuses, Barbier dit tout son pessimisme quant à l’avenir dans « Quatre-vingt-treize », chronique de la déchéance annoncée d’une génération – la sienne – incapable de faire une révolution aussi radicale que celle de ses aînés. « La Curée » le voit dénoncer la faim de pouvoir et d’honneurs caractéristique de ceux qui ont cherché leur seul profit dans les révolutions successives. Hanté par une descente aux Enfers qu’il pressent comme inéluctable, Barbier tend à la société née de 1830 le miroir déformant de la satire pour mieux lui faire saisir l’ampleur de sa médiocrité et de la déchéance qui l’attend. Maniant la véhémence dans une langue aussi dense que sobre, Barbier devient sitôt les Iambes parues le porte-parole d’une jeunesse populaire ; l’écho qu’il rencontre auprès d’elle se vérifiera tout au long du siècle. C’est que nul n’a dit comme lui, c’est-à-dire au travers d’un vers à la fois rude et sobre et d’images fortes que n’affecte aucun conformisme, l’émotion étreignant l’individu devant les mouvements populaires de juillet 1830 ; nul, surtout, n’a condensé d’aussi saisissante façon le symbolisme révolutionnaire, exalté comme le parfait contrepoint d’une époque sans valeurs ni figures héroïques. Nous nous pencherons sur les modalités de ce symbolisme révolutionnaire afin de déterminer l’image des Révolutions de 1789 et 1830 esquissée par Barbier et dont l’impact mémoriel devait être majeur tout au long du siècle. Il s’agira de dégager les thématiques déployées dans les Iambes, tout en examinant les caractéristiques énonciatives et sémantiques du recueil, afin de cerner au plus près l’imaginaire des mémoires révolutionnaires élaboré au gré d’alexandrins et d’octosyllabes égrenant, selon le mot de Baudelaire, « des pensées utiles et honnêtes » ; c’était là, sans doute, condenser ce qu’avait d’essentiellement, d’instinctivement révolutionnaire la poésie de Barbier.
