Parameter extraction and classification of three cortical neuron types reveals two distinct adaptation mechanisms. Cortical information processing originates from the exchange of action potentials between many cell types. In order to capture the essence of these interactions it is of critical importance to build mathematical models that reflect the characteristic features of spike generation in individual neurons.

Peak concentrations of biocides from house paint prove prevalent in urban river basins. Anti-fungal and anti-bacterial additives in house paint are present in dangerous quantities in the Vauchère river basin in the city of Lausanne, says a study to be presented the 9th of December, at the American Geophysical Union (AGU) conference in San Francisco.

Talk by Hans Gellersen December 15th, 15:15, Room BC410 Touch input and two-handed interaction were intensively studied in the mid 80's but it's taken 20 years for these ideas to emerge in the mainstream, with the advent of multi-touch interfaces.

An EPFL / ISREC team has shed new light on how cancer metastases develop. The results they have obtained will open the door to new therapeutic options for treating late stage cancers and preventing secondary tumors from growing. The proliferation of metastases is often the main cause of complications and death from cancer.

TGR5 activation inhibits Atherosclerosis by reducing macrophage inflammation and lipid loading.

A two-compartment mathematical model of neuroglial metabolism using [1-11C] acetate. Compared with 13C MRS studies, 11C radiotracer measurements provide a single uptake curve representing the sum of all labeled metabolites, without chemical differentiation, but with higher temporal resolution.

LTS5 will organize a workshop on high angular resolution diffusion MR Imaging (HARDI) at the IEEE International Symposium on Biomedical Imaging (ISBI 2012) conference (Barcelona, Spain, May 2-5 2012).

Interfacial Complexation Reactions of Sr2+ with Octyl(phenyl)-N,N-diisobutylcarbamoyl methylphosphine Oxide for Understanding Its Extraction in Reprocessing Spent Nuclear Fuels. Stoichiometry and complexation equilibrium constants for the extraction of strontium from spent nuclear fuels at water room-temperature ionic liquid (RTIL) interfaces are very important for medicinal use of radioisotopes and remediation of contaminated environments.

Global kinomic and phospho-proteomic analyses of the human malaria parasite Plasmodium falciparum. The role of protein phosphorylation in the life cycle of malaria parasites is slowly emerging. Here researchers from the Inserm-EPFL Joint Research Unit , headed by Christian Doerig , together with colleagues from UK and India, combine global phospho-proteomic analysis with kinome-wide reverse genetics to assess the importance of protein phosphorylation in Plasmodium falciparum asexual proliferation.

Melton and Professor Kaplan's work on climate change using a combined biophysical modelling, social science, and community engagement approach will be presented at the December meeting.

Attention is captured by nonretinotopic, noninformative cues. Attention is crucial for visual perception because it allows the visual system to effectively use its limited resources by selecting beha

The efficiency of solar thermal power plants is improved by more than 30% thanks to the combination of two technologies.

P-Rex1 is required for efficient melanoblast migration and melanoma metastasis. Metastases are the major cause of death from melanoma, a skin cancer that has the fastest rising incidence of any malignancy in the Western world. Molecular pathways that drive melanoblast migration in development are believed to underpin the movement and ultimately the metastasis of melanoma.

Population-specific expression analysis (PSEA) reveals molecular changes in diseased brain. Understanding molecular changes that occur in human diseases is the key to developing new drugs and therapies. In complex human tissues like brain or blood, however, the presence of heterogeneous cell types, each with a specific function and potentially different involvement in disease, makes this task very challenging.

Solar thermal systems are today the most efficient renewable choice for hot water production.

The relaxation of long-lived states (LLS) corresponds to the slow return to statistical thermal equilibrium between symmetric and antisymmetric proton spin states. This process is remarkably sensitive to the presence of external spins and can be used to obtain information about partial unfolding of proteins.

Electronics could be 100 times less energy-hungry thanks to a quantum phenomenon known as the tunnel effect - by 2017 in consumer electronics By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue.
