Dans la poésie et dans les théories poétiques et esthétiques d’Apollinaire, de Cendrars et de Reverdy, entre « Pâques à New York », « Zone » en 1912, et Le Manifeste du surréalisme de Breton en 1924, une fracture apparaît au niveau de la forme. Liée forcément à l’abandon de la mimèsis en tant qu’imitation de la réalité, cette nouvelle poétique se veut rupture nette avec le réalisme, mais rejoint également des conceptions vitalistes de la pensée de Nietzsche et de Whitman, et à travers une nouvelle poétique de l’image et du langage poétiques, dont l’ambition est paradoxalement de réinventer le « réalisme » dans la poésie par « rapprochement des réalités éloignées » (Reverdy). Ce sont notamment des dispositifs de la « poésie visuelle » qui produisent des effets au niveau de la lecture en tant qu’expérience et expérimentation à la fois. Quels sont les enjeux de cette « poétique de la réalité » ou de ce « lyrisme du réel » et sa place dans la modernité poétique ? Les expériences et expérimentations du corpus, lesquelles se caractérisent par la fracture des formes, et utilisation des fragments « bruts », des éléments de réalité, sont étudiés avec une approche phénoménologique, mais dans une perspective essentiellement esthétique. Le mérite de la phénoménologie merleau-pontyienne est de mettre en valeur les aspects corporaux de la perception, et c’est exactement dans ce sens-là que toutes ces expérimentations représentent des stratégies poétiques d’immersion du lecteur dans l’expérience esthétique et des dispositifs d’une réception corporelle qui est « instinctive », c'est-à-dire « pré-linguistique » et, selon l’expression de Merleau-Ponty, « pré-objective », concernant ainsi également l’invention linguistique, c'est-à-dire la poésie en tant que « parole parlante ».

A wide range of mathematical ideas could be used to develop and justify a formula for calculating the area of trapezoid. Those ideas lead to different strategies for finding out area of trapezoid that we classify in three groups: decomposing, enclosing and transforming strategies. Those strategies should be part of mathematics content knowledge for teaching. In this study we trace a change in structure of mathematics content knowledge of nine pre-service mathematics teachers as a result of using GeoGebra applets that visualize different approaches in finding out the area of trapezoid. We argue that engaging pre-service mathematics teachers to develop and justify formula for calculating the area of trapezoid using GeoGebra applets is a worth task that enhances pre-service mathematics teachers’ content knowledge for teaching. Our experiment confirmed that the use of Geogebra encourage pre-service mathematics teachers to uncover new ideas that lead them towards clearer justifications and easier way of proving formula for area of trapezoid. Keywords: Area of trapezoid, GeoGebra, content knowledge for teaching

Prion diseases are dementing illnesses with poorly defined neuropsychological features. This is probably because the most common form, sporadic Creutzfeldt‐Jakob disease, is often rapidly progressive with pervasive cognitive decline making detailed neuropsychological investigation difficult. This study, which includes patients with inherited, acquired (iatrogenic and variant) and sporadic forms of the disease, is the only large‐scale neuropsychological investigation of this patient group ever undertaken and aimed to define a neuropsychological profile of human prion diseases.

Two-dimensional semiconductors such as MoS2 are an emerging material family with wide-ranging potential applications in electronics, optoelectronics, and energy harvesting. Large-area growth methods are needed to open the way to applications. Control over lattice orientation during growth remains a challenge. This is needed to minimize or even avoid the formation of grain boundaries, detrimental to electrical, optical, and mechanical properties of MoS2 and other 2D semiconductors. Here, we report on the growth of high-quality monolayer MoS2 with control over lattice orientation. We show that the monolayer film is composed of coalescing single islands with limited numbers of lattice orientation due to an epitaxial growth mechanism. Optical absorbance spectra acquired over large areas show significant absorbance in the high-energy part of the spectrum, indicating that MoS2 could also be interesting for harvesting this region of the solar spectrum and fabrication of UV-sensitive photodetectors. Even though the interaction between the growth substrate and MoS2 is strong enough to induce lattice alignment via van der Waals interaction, we can easily transfer the grown material and fabricate devices. Local potential mapping along channels in field-effect transistors shows that the single-crystal MoS2 grains in our film are well connected, with interfaces that do not degrade the electrical conductivity. This is also confirmed by the relatively large and length-independent mobility in devices with a channel length reaching 80 μm.

The ultralow thermal conductivity $\kappa$ observed experimentally in intentionally roughened silicon nanowires (SiNWs) is reproduced in phonon Monte Carlo simulations with exponentially correlated real-space rough surfaces similar to measurement [J. Lim, K. Hippalgaonkar, S. C. Andrews, A. Majumdar, and P. Yang, Nano Lett. 12, 2475 (2012)]. Universal features of thermal transport are revealed by presenting $\kappa$ as a function of the normalized geometric mean free path $\bar\lambda$ ($0<\bar\lambda<1$); the diffusive (Casimir) limit corresponds to $\bar\lambda=1/2$. $\kappa$ vs $\bar\lambda$ is exponential at low-to-moderate roughness (high $\bar\lambda$), where internal scattering randomly interrupts phonon bouncing across the SiNW, and linear at high roughness (low $\bar\lambda$), where multiple scattering events at the same surface results in ultralow, amorphous-limit thermal conductivity.

Ceratomegilla ( Adaliopsis ) alpina (Villa & Villa, 1835) is a Pleistocene glacial relict with disjunctive distribution in high mountain areas of the Alps, Carpathians and the Bulgarian mountains, where it inhabits mountain meadows from 800 to 2.000 m a.s.l. (Fürsch 1967, Haviar 2003, Kovar 2007). Two ssp. are recognized, Ceratomegilla alpina alpina Villa & Villa, 1835, restricted to the Alps (Austria, France, Italy, Liechtenstein and Switzerland), and Ceratomegilla alpina redtenbacheri Capra, 1928 with a wider distribution, including Austria, Bulgaria, Germany, Poland, Romania, Slovakia and Ukraina (Kovar 2007, Canepari 2013). In comparison with C. a. alpina , C. a. redtenbacheri is characterized by smaller humeral red spot reaching half of elytra width and without sub-humeral black spot; posterior spot roundish or square (never stripe shaped); body more convex and less pointed posteriorly (Capra 1928).
