In order to explore the bursting oscillations and formation mechanism of memristive non-smooth systems, a third-order memristor model an external periodic excitation are introduced into dynamical system, novel 4D system with two-timescale is established. The divided two different subsystems by interface, which can be used simulate scenario where encounters circuit in practical application circu...

We find in experiments a linear dependence of ionization irradiation-induced degradations on pre-irradiation values the input bias current bipolar devices with simple stages. The is found to generally exist all studied cases different device types and irradiation conditions. A unique behavior energy distribution interface states (Dit) under suggested as origin observed phenomenon: generation tr...

Abstract The interface incompatibility between organic polymer and inorganic ceramic filler is a common phenomenon in polymer-based dielectric composites. In this paper, the Ar/CF 4 plasma used to modify CaTiO 3 particles, which improved dispersion of its compatibility with polytetrafluoroethylene (PTFE). findings demonstrate that growing argon (Ar) flow rate was beneficial enhance discharge in...

This paper presents an imaging approach for Multiple Input Output Ground Penetrating Radar (MIMO GPR) systems working in down-looking contactless mode. The exploits a linear approximation of the scattering phenomenon and is based on ray-based propagation model, which takes into account presence air-soil interface. Accordingly, Interface Reflection Point concept extended to case MIMO GPR. propos...

purpose: web sites are considered as an important tool on the internet and it has an important role in the utilization of students from the internet. in this study, we tried to evaluate iranian schools web sites. method: research population consists of 122 school websites. we used a check list for evaluation of school websites. findings: we found that all aspects of iranian school websites (aut...

recent research in the area of second language acquisition has proposed that bilinguals and l2 learners show syntactic indeterminacy when syntactic properties interface with other cognitive domains. most of the research in this area has focused on the pragmatic use of syntactic properties while the investigation of compliance with a grammatical rule at syntax-related interfaces has not received...

Spin injection across interfaces driven by ultrashort optical pulses on femtosecond timescales constitutes a new way to design spintronics applications. Targeted utilization of this phenomenon requires knowledge the efficiency non-equilibrium spin injection. From quantitative comparison ab initio time-dependent density functional theory and interface-sensitive, time-resolved non-linear experime...

BACKGROUND Analyses of the pore size distribution in 3D matrices such as the cell-hydrogel interface are very useful when studying changes and modifications produced as a result of cellular growth and proliferation within the matrix, as pore size distribution plays an important role in the signaling and microenvironment stimuli imparted to the cells. However, the majority of the methods for the...

This paper presents a synthesis of robustness evaluation on power RF LDMOS devices and its relation with electrical and physical behaviours after RF life-tests. It is important to understand the physical degradation mechanism effects and the liaison on drifts of critical electrical parameters after life ageing tests, in I-V such as threshold voltage (Vth), the feedback capacitance (Crss) in C-V...

Vascular acrosyndromes constitute a common reason for physician visits. They are associated with connective tissue disease; for example, 90% of patients with scleroderma experience Raynaud's phenomenon. The rheumatologist must strive to establish the diagnosis, to identify a potential underlying cause, and to prescribe effective treatment when the symptoms are incapacitating. Raynaud's phenomen...
