The increased pollution arising from different stages of producing, distributing, and disposing of electronics products highlights the importance of green operations (GO) in terms of process and product stewardship to mitigate environmental damages and satisfy the escalating social expectation for environmentally friendly operations in the electronics industry. Drawing on the natural-resourceba...

Spurious EM interactions within and between systems endanger and may disturb their proper functional performance. The prevention, elimination or suppression of such electromagnetic interference (EMI) to a satisfactory level constitutes the engineering discipline– EMC – ElectroMagnetic Compatibility. Its objective is preservation or recovery of expected performance of electronic systems at minim...

—With the evolving technological development of integrated circuits, ensuring electromagnetic compatibility (EMC) is becoming a serious challenge for electronic circuit and system manufacturers. Although electronic components must pass a set of EMC tests to ensure safe operations, the evolution over time of EMC is not characterized and cannot be accurately forecast. This paper presents an origi...

It has been recently confirmed that the magnitude of the EMC effect measured in electron deep inelastic scattering is linearly related to the Short Range Correlation scaling factor obtained from electron inclusive scattering. By using a x-rescaling approach we are able to understand the interplay between the quark-gluon and hadronic degrees of freedom in the discussion of the EMC effect. PACS. ...

4-Chlorobenzoyl-coenzyme A (4-CBA-CoA) dehalogenase catalyzes the hydrolytic dehalogenation of 4-CBA-CoA to 4-hydroxybenzoyl-CoA by using an active site Asp145 carboxylate as the nucleophile. Formation of the corresponding Meisenheimer complex (EMc) is followed by chloride ion expulsion to form arylated enzyme (EAr). The EAr is then hydrolyzed to product. In this paper, we report the kinetics f...

The purpose of this study is to validate Eclipse's electron Monte Carlo algorithm (eMC) in heterogeneous phantoms using radiochromic films and EGSnrc as a reference Monte Carlo algorithm. Four heterogeneous phantoms are used in this study. Radiochromic films are inserted in these phantoms, including in heterogeneous media, and the measured relative dose distributions are compared to eMC calcula...

The electron Monte Carlo (eMC) dose calculation algorithm of the Eclipse treatment planning system is based heavily upon Monte Carlo simulation of the linac head and modeling of the linac beam characteristics with minimal measurement of beam data. Commissioning of the eMC algorithm on multiple identical linacs provided a unique opportunity to systematically evaluate the algorithm with actual me...

In hierarchical learning machines such as neural networks, Bayesian learning provides better generalization performance than maximum likelihood estimation. However, its accurate approximation using Markov chain Monte Carlo (MCMC) method requires huge computational cost. The exchange Monte Carlo (EMC) method was proposed as an improved algorithm of MCMC method. Although its effectiveness has bee...

We calculated the contribution of the photon hadronic component in the charmed structure function of the leptoproduction. The contribution comes from scattering of the c quarks of the virtual photon on the quarks and gluons of the proton. Comparison of our calculations with the measurements of the charm production in µ + p-scattering by EMC shows, that contribution of resolved photon can explai...
