The complexity of today’s chips is such that relying solely upon external ATE resources is insufficient for scan test. In this work, we develop the concept of dedicated autonomous scan-based testing (DAST) by proposing a scheme that introduces hierarchy and separates the functionality of ATE resources into two distinctive classes: a) test data communication, and b) test data control and observa...

We present the development and validation of Digital Addiction Scale for Teenagers (DAST), describing pilot study ( N = 40 students) main 4493) with Estonian students aged 11–19, in spring 2020. Our aim was to create a scale suitable psychoeducational assessment teenagers’ behaviour feelings towards digital devices. used mixed research framework . Half sample collected before coronavirus crisis...

We report on the electro-optic and nonlinear optical properties of waveguides produced by low fluence (Phi = 1.25x10(14) ions/cm(2)) H+ ion implantation in the organic nonlinear optic crystal 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium tosylate (DAST). The profile of the nonlinear optical susceptibility has been determined by measuring the reflected second-harmonic generation efficiency from ...

Infrared pulses with large spectral width extending from 1.2 to 3.4 μm are generated in the organic crystal DAST (4-N, N-dimethylamino-4′-N′-methylstilbazolium tosylate). The input pulse has a central wavelength of 1.5 μm and 65 fs duration. With 2.8 mJ input energy we obtained up to 700 μJ in the broadened spectrum. The output can be easily scaled up in energy by increasing the crystal size to...

Amaç: Bu çalışmanın amacı buprenorfin/nalokson (BN) idame tedavisi altındaki hastalarda 6 aylık izlem süresinde seyrin belirleyicilerini araştırmaktı. Yöntem: Çalışmaya kliniğimize yatışı yapılan (n=106, %27.04) ya da ayaktan BN idame tedavisi programına alınan (n=286, %72.96) ardışık 392 eroin bağımlısı hasta alındı.

Nowadays, using photovoltaic (PV) cells is among the power generation methods that absorb solar energy and convert it into electrical energy. The sun moves from east to west during day its radiation angle changes relative Earth in different seasons. So, output of PV panels as well. increases by being located a position perpendicular sun's rays. This study aims design implement dual-axis tracker...

1,6-Dideoxy-6,6-difluoronojirimycin (1) was prepared from an easily accessible and commercially available starting material, methyl 2,3,4-tri-O-benzyl-α-D-glucopyranoside. Key steps of this synthesis are a difluorination reaction using DAST and a reductive amination. The overall yield of the synthesis is 44%. Compound 1 has been tested for its activity as an inhibitor of various glucosidases an...
