Design Concerns for In-body Antennas Based on Frequency Analysis of Fundamental Radiation Limitations

Anja Skrivervik, Denys Nikolayev

Fundamental radiation limitations of in-body or implantable antennas should give us an estimate on the feasibility of some desired system. It was shown that near-field effects and distance to the body - freespace boundary are critical aspects, while the sh ...

Smaller, Faster & Lighter KNN Graph Constructions

Rachid Guerraoui, Anne-Marie Kermarrec

We propose GoldFinger, a new compact and fast-to-compute binary representation of datasets to approximate Jaccard’s index. We illustrate the effectiveness of GoldFinger on the emblematic big data problem of K-Nearest-Neighbor (KNN) graph construction and s ...

Numerical analysis for detecting head losses in trifurcations of high head in hydropower plants

François Avellan

Many different types of branching have been developed, such as bifurcation, trifurcation, and manifolds, among others. These configurations are used in penstocks to transport water from surge tanks to power houses in order to feed several turbines at the s ...

Experimental assessment of head losses through elliptical and sharp-edged orifices

Anton Schleiss, Giovanni De Cesare, Nicolas Jean François Pascal Ghislain Adam

Due to the European electricity market liberalization and the appearance of other renewable electricity producers, an increase of installed peak power capacity is relevant to provide larger amount of electricity in a shorter turbine duration. When the disc ...

Human audiometric thresholds do not predict specific cellular damage in the inner ear

Demetri Psaltis

Introduction: As otology enters the field of gene therapy and human studies commence, the question arises whether audiograms - the current gold standard for the evaluation of hearing function - can consistently predict cellular damage within the human inne ...

Fast particle loss channels in Wendelstein 7-X

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Jonathan Marc Philippe Faustin

One of the main goals of Wendelstein 7-X (W7-X) is to demonstrate the fast particle confinement properties of the quasi-isodynamic stellarator concept. Fast particle populations will be produced either by Neutral Beam Injection (NBI) or by minority Ion Cyc ...

Head loss coefficient through sharp-edged orifices

Anton Schleiss, Giovanni De Cesare, Cécile Münch-Alligné, Nicolas Jean François Pascal Ghislain Adam

Nowadays, high-head power plants could increase their installed power capacity for many reasons, e.g. dam heightening, increase of their peak power capacity or refurbishment with new turbines. Frequently, due to several considerations, e.g. topographical o ...

Shear-Fatigue Behaviour of RC Cantilever Bridge Deck Slabs under Concentrated Loads

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário

Shear has been observed to be the governing failure mode of RC cantilever deck slabs of bridges without shear reinforcement when subjected to concentrated loads of heavy vehicles. This observation has been verified experimentally for a quasi-static applica ...

Constitutive gray hair in Mice induced by Melanocyte-specific deletion of c-Myc

Friedrich Beermann, Marzia Armaro

c-Myc is involved in the control of diverse cellular processes and implicated in the maintenance of different tissues including the neural crest. Here we report that c-Myc is particularly important for pigment cell development and homeostasis. Targeting c- ...

The Role of LEKTI in the Fate Determination of Keratinocyte Stem Cells

Alessandro Wataru Amici

SPINK5 (serine protease inhibitor Kazal-type 5) encodes the proteinase inhibitor LEKTI (lympho-epithelial Kazal-type related inhibitor). In skin, LEKTI expression is restricted to the stratum granulosum of the epidermis and the inner root sheath of hair fo ...

A silicon model of the inner hair cell

Yusuf Leblebici

In this paper we present an electrical model of the inner hair cell based on an improved mathematical model. The model is implemented in silicon in the current domain using translinear circuits. It improves on previous models by taking into consideration t ...

Key roles for transforming growth factor beta in melanocyte stem cell maintenance

Friedrich Beermann

Melanocyte stem cells in the bulge area of hair follicles are responsible for hair pigmentation, and defects in them cause hair graying. Here we describe the process of melanocyte stem cell entry into the quiescent state and show that niche-derived transfo ...

Acquisition et recalage informatique d'images confocales de tissus denses : application à l'étude de la papille folliculaire de vibrisse de souris

Analysis of the 3D structure of a biological sample is an important step to model cell and tissue dynamics. As a model system, we set up to determine the number of nuclei in a follicular papilla using confocal imaging and 3D computer reconstruction. The fo ...

Epithelial stem cells and mechanical signal transduction : a functional unit?

Vincent Bernard Cattin

Hair follicles are cutaneous structures characteristic of mammals. These sensitive organs cycle and contain multipotent epithelial stem cells which are implicated in hair growth and hair cycle. A single whisker follicle of the rat hosts up to 1500 stem cel ...

Control of thrombin signaling through PI3K is a mechanism underlying plasticity between hair follicle dermal sheath and papilla cells

Yann Barrandon

In hair follicles, dermal papilla (DP) and dermal sheath (DS) cells exhibit striking levels of plasticity, as each can regenerate both cell types. Here, we show that thrombin induces a phosphoinositide 3-kinase (PI3K)-Akt pathway-dependent acquisition of D ...

Notch1 is essential for postnatal hair follicle development and homeostasis

Freddy Radtke, Yann Barrandon

Notch genes encode evolutionarily conserved large, single transmembrane receptors, which regulate many cell fate decisions and differentiation processes during fetal and postnatal life. Multiple Notch receptors and ligands are expressed in both developing ...
