in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...
Analysis of the tidal stress tensor at the time of moderate to large earthquakes fails to confirm an earlier hypothesis that the origin times of shallow dip-slip earthquakes correlate with solid-earth tidal shear stress, Furthermore, no correlation is seen for either tidal shear stress or tidal normal-to-the-fault compressive stress with shallow strike-slip earthquakes or with deep earthquakes....
Hazard assessment of shallow landslides represents an important aspect of land management in mountainous areas. Among all the methods proposed in the literature, physically based methods are the only ones that explicitly includes the dynamic factors that control landslide triggering (rainfall pattern, land-use). For this reason, they allow forecasting both the temporal and the spatial distribut...
Landslides triggered by strong earthquakes often caused most of the global damage and most of all casualties related to the events, such as shown by the M = 7.7 Peru earthquake in 1970, by the M = 7.6 El Salvador earthquake in 2001 or by the M = 7.4 Khait (Tajikistan) earthquake in 1949. The obvious impact of a landslide on the population is directly related to its movement. Yet, prediction of ...
Morphologies of z∼0.7 AGN Host Galaxies in CANDELS: No trend of merger incidence with AGN luminosity
The processes that trigger Active Galactic Nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger disturbances are likely required to trigger luminous AGN. Major wet mergers of galaxies are ideal environments for AGN triggering since they provide large gas supplies and galaxy scale torques. There is however little ob...
We have recently identified that the ligand of natural cytotoxicity triggering receptor 2 (NCR2, best known as NKp44) is expressed on a large panel of malignant cells. This ligand provides a new tool to investigate how stressed cells are recognized and eliminated by natural killer (NK) cells, and to develop novel immunotherapeutic paradigms against cancer.
In models of triggered seismicity and in their inversion with empirical data, the detection threshold md is commonly equated to the magnitude m0 of the smallest triggering earthquake. This unjustified assumption neglects the possibility of shocks below the detection threshold triggering observable events. We introduce a formalism that distinguishes between the detection threshold md and the min...
Background and purpose: Osteoarthritis is the most common type of arthritis. It is the main cause of chronic musculoskeletal pain and disability in elderly population. The aim of this research was to compare the effects of low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) on pain relief and reducing disability in patients with knee osteoarthritis. Materials and methods: A ...
Background: Laser treatment is a rapid, non-invasive procedure for long-term hair removal. Lasers operate based on the principle of selective photothermolysis and target melanin in the hair follicle. We intend to determine the level of hirsute patient satisfaction with the alexandrite laser hair removal procedure.Methods: In this cross-sectional study 82 hirsute patient...
We study the creation of vortices by triggering rotating Bose-Einstein condensates in a toroidal trap with parameters such as laser beam waist and Gaussian potential depth. By numerically solving time-dependent Gross-Pitaevskii equation two dimensions, we observe change vortex structure considerable increase number when irradiated is consonance area condensate vary computing root mean square ra...
