Extensive scanning tunneling microscopy and spectroscopy experiments complemented by first-principles and parametrized tight binding calculations provide a clear answer to the existence, origin, and robustness of van Hove singularities (vHs) in twisted graphene layers. Our results are conclusive: vHs due to interlayer coupling are ubiquitously present in a broad range (from 1° to 10°) of rotati...

Abstract The rapid changes in industrial revolution 4.0 demand change education, especially at vocational education. Teachers Vocational High School (VHS) Indonesia are expected to bring technology-based innovations achieve success learning. Learning facilities one of the factors supporting learning class. Ideally, Indonesian Schools have and infrastructure following industrial. Currently, scho...

This paper proposes a new emotional model for Virtual Humans (VHs) in a conversational environment. As a part of a multi-users emotional 3D-chatting system, this paper focus on how to formulate and visualize the flow of emotional state defined by the Valence-ArousalDominance (VAD) parameters. From this flow of emotion over time, we successfully visualized the change of VHs’ emotional state thro...

We examine the effects of a van Hove singularity (vHs) in the density of states (DOS) of a two dimensional, t− t−U Hubbard model within the local approximation. Within our approximation the non-interacting Fermi surface is always retained away from half-filling; and we find that the vHs in the DOS survives, and for hole doping is nearly ”pinned” to the Fermi level due to the enhancement of the ...

In two-dimensional (2D) lattices, the electronic levels are unevenly spaced, and the density of states (DOS) displays a logarithmic divergence known as the Van Hove singularity (VHS). This is the case in particular for the layered cuprate superconductors. The scanning tunnelling microscope (STM) probes the DOS, and is therefore the ideal tool to observe the VHS. No STM study of cuprate supercon...

Virtual human (VH) experiences are increasingly used for training interpersonal skills such as military leadership, classroom education, and doctor-patient interviews. These diverse applications of conversational VHs have a common and unexplored thread – a significant additional population would be afforded interpersonal skills training if VHs were available to simulate either interaction partn...

The BGK and BGKC (Bhatnagar, Gross, Krook, and Cercignani) collision-term models for the Boltzmann equation are compared to the more rigorous variable-hard-sphere (VHS) collision-term model of Bird. The BGKC model is based on the well-known BGK model but uses an ellipsoidal statistical (ES) distribution instead of a Maxwellian distribution so as to incorporate both viscous effects and heat cond...

Swiss aquaculture farms were assessed according to their risk of acquiring or spreading viral haemorrhagic septicaemia (VHS) and infectious haematopoietic necrosis (IHN). Risk factors for the introduction and spread of VHS and IHN were defined and assessed using published data and expert opinions. Among the 357 aquaculture farms identified in Switzerland, 49.3% were categorised as high risk, 49...

One of the most valuable aquaculture fish in Europe is the rainbow trout, Oncorhynchus mykiss, but the profitability of trout production is threatened by a highly lethal infectious disease, viral hemorrhagic septicemia (VHS), caused by the VHS virus (VHSV). For the past few decades, the subgenogroup Ia of VHSV has been the main cause of VHS outbreaks in European freshwater-farmed rainbow trout....

BACKGROUND Vertebral hemangioma (VH) is considered to be a benign lesion of bone with a rich vasculature. Most incidentally discovered hemangiomas are asymptomatic. Percutaneous vertebroplasty (PVP) has demonstrated efficacy in the treatment of symptomatic thoracic and lumbar VHs. To our knowledge, the reports concerning PVP on symptomatic cervical VHs are quite rare. OBJECTIVE Our intent was...
