Influence of probe flexibility and gelatin embedding on neuronal density and glial responses to brain implants.

To develop long-term high quality communication between brain and computer, a key issue is how to reduce the adverse foreign body responses. Here, the impact of probe flexibility and gelatine embedding on long-term (6w) tissue responses, was analyzed. Probes of same polymer material, size and shape, flexible mainly in one direction, were implanted in rat cerebral cortex (nimplants = 3 x 8) in two

Quantitative image contrast enhancement in time-gated transillumination of scattering media

Experimental work in turbid media has shown that transillumination images can be significantly improved by limiting light collection to a subset of photons which are minimally distorted by scattering. The literature details numerous schemes (commonly termed ballistic imaging), most often based on time-gating and/or spatially filtering the detected light. However, due to the complex nature of the d

After 50 years the Alliance for Progress was launched, the policies for territorial planning in Latin America have proved to fail. The WB and the IADB, instruments of the US international politics for the consolidation of its global and regional hegemony, are its main financial and doctrinaire sources. These agencies’ logics prevail in the general and territorial planning. In the aftermath of the

Growth of TiO2(B)(001) on Au(111) by chemical vapor deposition

This study presents how a TiO2(B) film exposing the (001) face can be grown on Au(111) by chemical vapor deposition. Identification and characterization of the TiO2(B)(001) layer are carried out with low-energy electron diffraction (LEED), synchrotron radiation photoelectron spectroscopy (PES), scanning tunneling microscopy (STM) and X-ray absorption spectroscopy (XAS). Formation of the TiO2(B) fi

Importers, Exporters, and Multinationals : Exploring the Hierarchy of International Linkages

The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages, using data on Swedish manufacturing firms from 1997 to 2007. First, we investigate the productivity ordering with respect to three international linkages; importing, exporting and investing abroad. Second, we explore whether differences in the productivity ordering ac

The influence of ferrous sulfate utilization on the sugar yields from dilute-acid pretreatment of softwood for bioethanol production.

By employing metal salts in dilute-acid pretreatment the severity can be reduced due to reduced activation energy. This study reports on a dilute-acid steam pretreatment of spruce chips by addition of a small amount of ferrous sulfate to the acid catalyst, i.e., either SO(2), H(2)SO(3) or H(2)SO(4). The utilization of ferrous sulfate resulted in a slightly increased overall glucose yield (from 74%

Search for diphoton events with large missing transverse energy with 36 pb(-1) of 7 TeV proton-proton collision data with the ATLAS detector

Making use of 36 pb(-1) of proton-proton collision data at root s = 7 TeV, the ATLAS Collaboration has performed a search for diphoton events with large missing transverse energy. Observing no excess of events above the Standard Model prediction, a 95% Confidence Level ( CL) upper limit is set on the cross section for new physics of sigma < 0.38-0.65 pb in the context of a generalised model of gau

Device discovery for the PalCom pervasive middleware with eliminated cross-networks periodic heart-beat messages

Service discovery is central in pervasive middleware systems, built on top of the communication substrate using the more fundamental mechanisms for device discovery. In mobile pervasive systems devices come and go, and switch network frequently, demanding support for device discovery across heterogeneous networks. We present the design of a device discovery mechanism for the PalCom middleware that

Methods to explore design space for MPEG RVC codec specifications

Abstract in UndeterminedThe recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementation on specific targets. To this end, the RMC framework has standardized both an asynchronous dataflow model of computat

Suppression of renal cell carcinoma growth by inhibition of Notch signaling in vitro and in vivo

Loss of the tumor suppressor gene von Hippel–Lindau (VHL) plays a key role in the oncogenesis of clear cell renal cell carcinoma (CCRCC). The loss leads to stabilization of the HIF transcription complex, which induces angiogenic and mitogenic pathways essential for tumor formation. Nonetheless, additional oncogenic events have been postulated to be required for the formation of CCRCC tumors. Here,

Manual lymphatic drainage for lymphedema following breast cancer treatment

Background More than one in five patients who undergo treatment for breast cancer will develop breast cancer-related lymphedema (BCRL). BCRL can occur as a result of breast cancer surgery and/or radiation therapy. BCRL can negatively impact comfort, function, and quality of life (QoL). Manual lymphatic drainage (MLD), a type of hands-on therapy, is frequently used for BCRL and often as part of com

A Survey on Vehicle-to-Vehicle Propagation Channels

Traffic telematics applications are currently under intense research and development for making transportation safer, more efficient, and more environmentally friendly. Reliable traffic telematics applications and services require vehicle-to-vehicle wireless communications that can provide robust connectivity, typically at data rates between 1 and 10 Mb/s. The development of such VTV communication

Searching for new convolutional codes using the cell broadband engine architecture

The Bidirectional Efficient Algorithm for Searching code Trees (BEAST), which is an algorithm to efficiently determine the free distance and spectral components of convolutional encoders, is implemented for the Cell Broadband Engine Architecture, efficiently utilizing the underlying hardware. Exhaustive and random searches are carried out, presenting new rate R=1/2 convolutional encoding matrices

Gene duplication and fragmentation in the zebra finch major histocompatibility complex

Background: Due to its high polymorphism and importance for disease resistance, the major histocompatibility complex (MHC) has been an important focus of many vertebrate genome projects. Avian MHC organization is of particular interest because the chicken Gallus gallus, the avian species with the best characterized MHC, possesses a highly streamlined minimal essential MHC, which is linked to resis

Activation of nuclear factor-kappa B pathway is responsible for tumor necrosis factor-a-induced up-regulation of endothelin B2 receptor expression in vascular smooth muscle cells in vitro

The endothelin B2 (ETB2) receptors are induced in vascular smooth muscle cells (VSMCs) in cardiovascular diseases. We tested if in vitro short-term exposure to the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) could up-regulate ETB2 receptors in rat mesenteric arteries, and if this effect is through activation of intracellular nuclear factor-kappa B (NF-kappa B) pathway. The me

Hypnosis as an adjunct therapy in the management of diabetes

Although diabetes is one of the most serious global health problems, there is no real cure yet for it. The conventional insulin treatment programs aimed at life quality improvement do not take into account the psychological aspects of the disease. Because diabetes has important psychological components, it seems reasonable to consider hypnosis as an adjunct therapy for diabetes. This paper examine

Followership in Higher Education: Academic Teachers and their Formal Leaders

The concept of followership in higher education has been given limited attention despite the fact that followers are key players in the follower/leader equation and that leadership is increasingly seen as vital to improving the student learning experience. This paper explores this concept, reporting on the findings of a qualitative study underpinned by a socio-constructivist framework. Thirty-eigh
