background: solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109cd. to avoid cracking or peeling of the target during bombardment, it should have a level surface a...

neural mass models are computational nonlinear models that simulate the activity of a population of neurons as an average neuron, in such a way that different inhibitory post synaptic potential (ipsp) and excitatory post synaptic potential (epsp) signals could be reproduced. these models have been developed either to simulate the recognized neural mechanisms or to predict some physiological fac...

This application note describes the powerful fusion of fluorescence lifetime imaging microscopy with two-photon excitation (2P-FLIM) by using the PicoQuant time-resolved confocal fluorescence microscope MicroTime 200. The intracellular ion homeostasis in living cells is one requirement for optimal physiological functionality in living systems. One of the most prominent features in living organi...

Adaptive extremum-seeking controllers are used to handle uncertainties in the modelling of industrial processes. Although these controllers are capable to handle uncertain parameters, an additional persistence of excitation condition is necessary to prove the convergence of these unknown parameters to their true values. If complex non-linear models are used it is not dear how this condition can...

Coherence and de-coherence are the most fundamental steps that follow initial photo-excitation occurring in typical Pump&Probe experiments. Indeed, external laser pulse transfers coherence to system terms of creation multiple electron-hole pairs excitation. The excitation concurs both a finite carriers density appearance induced electromagnetic fields. two effects, very first approximation, can...

Excitation of molecules by incident incoherent electromagnetic radiation, such as sunlight, is described in detail and contrasted with the effect coherent (e.g. laser) light. The nature quantum coherences induced former, relevant to transport processes technology, emphasized. Both equilibrium steady state scenarios are discussed, Three examples: simple models, calcium excitation polarized light...

One mechanism used by plants to protect against damage from excess sunlight is called nonphotochemical quenching (NPQ). Triggered by low pH in the thylakoid lumen, NPQ leads to conversion of excess excitation energy in the antenna system to heat before it can initiate production of harmful chemical species by photosynthetic reaction centers. Here we report a synthetic hexad molecule that functi...

In this work, we present an experimental study of dissociative excitation of CH4 utilizing a crossed electron molecular beam experiment. Methane was excited by nearly monochromatic electrons generated by a trochoidal electron monochromator. The dissociative products were identified on the basis of the emission spectra in the ultraviolet–visible (UV/VIS) spectral range. The excitation functions ...

Future combinations of plasmonics with nanometer-sized electronic circuits require strategies to control the electrical excitation of plasmons at the length scale of individual molecules. A unique tool to study the electrical plasmon excitation with ultimate resolution is scanning tunneling microscopy (STM). Inelastic tunnel processes generate plasmons in the tunnel gap that partially radiate i...

We study selfand cross-excitation of shocks in the Eurozone sovereign CDS market. We adopt a multivariate setting with credit default intensities driven by mutually exciting jump processes, to capture the salient features observed in the data, in particular, the clustering of high default probabilities both in time (over days) and in space (across countries). The feedback between jump events an...
