Prognostic significance of clinical seizures after cardiac arrest and target temperature management
Aim: Clinical seizures are common after cardiac arrest and predictive of a poor neurological outcome. Seizures may be myoclonic, tonic-clonic or a combination of seizure types. This study reports the incidence and prognostic significance of clinical seizures in the target temperature management (TTM) after cardiac arrest trial. Our hypotheses were that seizures are associated with a poor prognosis

Genre
The concept of genre is scrutinized as a semantic phenomenon, and it is argued that the concept of genre must be defined according to a pragmatic semantic, not a realistic. Genres are not logical classes. The analytic practice is then connected to this way of defining the concepts: it is governed by how the culture using the concept understands the word. An analysis of a letter of Mme de Sévigné d
Comparative genomics and expression levels of hydrophobins from eight mycorrhizal genomes
Hydrophobins are small secreted proteins that are present as several gene copies in most fungal genomes. Their properties are now well understood: they are amphiphilic and assemble at hydrophilic/hydrophobic interfaces. However, their physiological functions remain largely unexplored, especially within mycorrhizal fungi. In this study, we identified hydrophobin genes and analysed their distributio
Social and environmental value-based cluster development : The dilemma of wishing to do good by selling textile goods
Can the meiotic sex ratio explain the sex ratio bias in adult populations in the dioicous moss Drepanocladus lycopodioides?
Sex ratio variation is commonly observed in natural populations of many organisms with separate sexes and genetic sex determination, including bryophytes. Most bryophyte populations exhibit female-skewed expressed adult sex ratios, generally inferred from counts of sexually mature plants. For the rarely sexually reproducing perennial dioicous moss Drepanocladus lycopodioides, we showed that a fema
Self-Adaptive Video Encoder : Comparison of Multiple Adaptation Strategies Made Simple
This paper presents an adaptive video encoder that can be used to compare the behavior of different adaptation strategies using multiple actuators to steer the encoder towards a global goal, composed of multiple conflicting objectives. A video camera produces frames that the encoder manipulates with the objective of matching some space requirement to fit a given communication channel. A second obj
Lateral InAs/Si p-Type Tunnel FETs Integrated on Si - Part 1 : Experimental Devices
Tunnel FETs (TFETs) have been identified as the most promising steep slope devices for ultralow power logic circuits. In this paper, we demonstrate in-plane InAs/Si TFETs monolithically integrated on Si, using our recently developed template-assisted selective epitaxy approach. These devices represent some of the most scaled TFETs with dimensions of less than 30 nm, combined with excellent aggrega
Handling New and Changing Requirements with Guarantees in Self-Adaptive Systems using SimCA
Self-adaptation provides a principled way to deal with change during operation. As more systems with strict goals require self-adaptation, the need for guarantees in self-adaptive systems is becoming a high-priority concern. Designing adaptive software using principles from control theory has been identified as one of the approaches to provide guarantees. However, current solutions can only handle
CX3C chemokine receptor 1 deficiency modulates microglia morphology but does not affect lesion size and short-term deficits after experimental stroke
Background: The fractalkine/CX3C chemokine receptor 1 (CX3CR1) pathway has been identified to play an essential role in the chemotaxis of microglia, leukocyte trafficking and microglia/macrophage recruitment. It has also been shown to be important in the regulation of the inflammatory response in the early phase after experimental stroke. The present study was performed to investigate if CX3CR1 de
Investigation of doping in InAs/GaSb hetero-junctions for tunnel-FETs
We report on the influence of doping on the band-edge abruptness of InAs/GaSb p-n and p-i-n tunnel diodes. Understanding and fabrication of a well-defined and sharp band edge is mandatory for tunnel FET operation. InAs/GaSb nanowire junctions were selectively grown by metal organic chemical vapor deposition (MOCVD) on silicon-on-insulator (SOI) substrates using template assisted selective epitaxy
Complementary III-V heterojunction lateral NW Tunnel FET technology on Si
We demonstrate for the first time a technology which allows the monolithic integration of both p-Type (InAs-Si) and n-Type (InAs-GaSb) heterojunction Tunnel FETs (TFET) laterally on a Si substrate. The lateral heterojunction nanowire (NW) structures are implemented using top-down CMOS-compatible processes combined with Template-Assisted Selective Epitaxy (TASE) [1] of the III-V materials. Sub-40nm
III-V heterojunction nanowire tunnel FETs monolithically integrated on silicon
In this presentation we will discuss our recent progress on the integration of InAs/Si p-tunnel FETs (TFETs) and InAs/GaSb n-TFETs on SOI wafers. Local III-V growth is enabled by the development of Template-Assisted Selective Epitaxy (TASE) [1-4]. Both polarity devices have scaled geometries with cross-sections on the order of 30nm. The p-channel InAs/Si TFETs are developed based on our previously
Lateral InAs/Si p-Type Tunnel FETs Integrated on Si - Part 2 : Simulation Study of the Impact of Interface Traps
This part of the paper presents TCAD simulations of the InAs/Si lateral nanowire (NW) tunnel FET (TFET) with the same geometry as the fabricated device discussed in the first part. In addition to band-to-band tunneling, trap-assisted tunneling (TAT) at the InAs/Si and InAs/oxide interfaces was considered. A very good agreement is found between the simulation results and experimental transfer chara
Fabrication and analysis of vertical p-type InAs-Si nanowire tunnel FETs
We report InAs-Si nanowire (NW) Tunnel FETs fabricated inside nanotube templates. High device yield and performances are obtained by optimizing the growth conditions and the fabrication flow using inorganic material as dielectric spacer, atomic-layer-deposition for the metal gate and by scaling the equivalent oxide thickness (EOT). We extract the exponential parameter B of Kane's tunneling model f
Single-Cell Analysis Reveals a Close Relationship between Differentiating Dopamine and Subthalamic Nucleus Neuronal Lineages
Stem cell engineering and grafting of mesencephalic dopamine (mesDA) neurons is a promising strategy for brain repair in Parkinson's disease (PD). Refinement of differentiation protocols to optimize this approach will require deeper understanding of mesDA neuron development. Here, we studied this process using transcriptome-wide single-cell RNA sequencing of mouse neural progenitors expressing the
Near to far field transformation of RCS using a compressive sensing method
Near field Inverse Synthetic Aperture Radar Cross Section (RCS) measurements are used in this study to obtain geometrically correct images of objects placed on a turntable. The images of the targets are processed using a method common in the compressive sensing field, Basis Pursuit Denoise. A near field model based on isotropic point scatterers is set up. The target model is naturally sparse and t
Comparative study on the machinability of lead-free brass
Lead is a heavy metal which is toxic even at low exposure levels. Although the amount of lead used in industry is steadily declining, it still constitutes a common alloying element for most conventional brass varieties. Today, conventional brasses contain roughly 3 wt % lead. One of the main incentives for using lead as an alloying element is that it has a markedly positive effect on the machinabi
