Computer stimulations of particulate recording media
In order to further understand the behaviour of magnetic recording media the relationship between the microscopic and the macroscopic behaviour must be more precisely understood. Computer simulations are an invaluable tool in the development and testing of models of these media. Presented here are …

Extended mechanical stimulations of cartilage for growth and repair
Extended mechanical stimulation of articular cartilage in an in vitro model explant system promotes growth and repair. An alternating day mechanical loading protocol consisting of dynamic sinusoidal compression results in long term extracelluar matrix macromolecule biosynthesis and increased …

Stimulations and modulations of chondrogenic differentiation of human embryonic stem cells
By using human embryonic stem cells (hESCs) as the model system, this study aims to understand the full span process of chondrogenesis, and how this process could be regulated by growth factors BMP2 and/or TGFI?1 in a controlled context both in vitro and in vivo. By culturing hESCs in 2-D EB …

On synchrony and social relations: the role of synchronous multisensory stimulations in self-other merging, social bonding and ingroup-bias reduction
In psicologia sociale, e in particolare negli studi sulle relazioni intime e le relazioni all’interno del gruppo d’appartenenza, è stato osservato come le persone con cui abbiamo dei legami (e.g., partner, amici, membri del nostro gruppo) siano incluse nella rappresentazione del sé. Nella …

Nervous control of the lungs: broncho- and vaso motor responses of guinea-pig lungs, produced by drug injections and nerve stimulations
… outflow. (5) Only 3 responses were obtained with stimulations of the peripheral ends of cut cervical sympatheti In one a rise in I.P.P. was obtained; the flow wa not recorded. In other two responses occurred after an administration of Ergotoxine - a fall in I.P.P. with no change or a questionable …

Non invasive brain stimulation : modeling and experimental analysis of transcranial magnetic stimulations and transcranial DC stimulation as a modality for neuropathology treatment
This thesis will explore the use of Transcranial Magnetic Stimulation (TMS) and Transcranial DC Stimulation (tDCS) as modalities for neuropathology treatment by means of both experimental and modeling paradigms. The first and primary modality that will be analyzed is Transcranial Magnetic …

THE MECHANISM OF JUNB TRANSCRIPTIONAL REGULATION UNDER TLR ACTIVATION IN MOUSE MACROPHAGES
… were induced under single and combinatorial PAMP stimulations in macrophages. A junb downstream enhancer region significantly up-regulates junb transcription when cooperating with junb promoter. Mutagenesis analysis showed that four NF-?B sites in junb enhancer region are important for junb …

Les stimulation quotidiennes du nourrisson et sa performance à une tâche d'habituation visuelle
… et du tempérament du nourrisson. En évaluant les stimulations sociales du nourrisson à la maison, cette recherche a pour second objectif de vérifier la validité écologique des liens entre les stimulations accordées par les parents et le fonctionnement cognitif du nourrisson, tel que défini par sa …

Fluorescence resonance energy transfer-based subcellular visualization of FAK/Src activation by chemical and mechanical environment
… of plasma membrane. In response to chemical stimulations, the activation of Src population at lipid rafts was slower and weaker compared to that outside lipid rafts. In contrast, FAK biosensors targeted to different membrane microdomains revealed that FAK activation mainly occurs at lipid …

Reservoir characterization and geology of the coals and carbonaceous shales of the Cherokee group in the Cherokee Basin, Kansas, Missouri and Oklahoma, U.S.A.
… permeability. The majority of hydraulic fracture stimulations used slick water, but cross-linked gel and nitrogen have proven to be as effective but were more expensive. The study found that a single stimulation of a single zone is more productive than multiple stimulations with multiple zones. …

Assessing the role of the hippocampus in amygdala kindled fear : an analysis of environmental habituation
… environment. Rats that had received 30 or 60 stimulations demonstrated hyperexploratory behaviour and elevated fear, although this behaviour did dissipate to a certain degree by the final day of testing. Long-term kindled rats, having received 99 stimulations, demonstrated extremely heightened …

Galvanic Vestibular Stimulation Applied to Flight Training
… Bilateral bipolar rectangular pulse electrical stimulations were given to subjects via skin-mounted electrodes placed over each mastoid process to stimulate the vestibular system with roll and yaw sensations. Two studies were conducted in this work: one on motion sensitivity and one to examine …

Imaging the Soultz Enhanced Geothermal Reservoir using double-difference tomography and microseismic data
… reservoir's September and October 1993 hydraulic stimulations along with starting event locations obtained using Joint Hypocenter Determination and Collapsing methods. The stimulations produced over 12000 microseismic events of which we chose 8930 for further analysis. We obtained high accuracy …

Investigating neuronal network dynamics : scale-invariance, preferred firing rates, and plasticity via phase-shift encoding
… inhomogeneous Poisson point process (IPP) stimulations, spike-timing-dependent plasticity (STDP) protocols, and phase-shift encoding experiments, we investigated neuronal network dynamics. Preferred firing rates were identified across multiple neural circuits in an iterative design process, …
