We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges. As is typical for any bound state, their g factor depends on both an intrinsic g factor of the material and an additional contribution arising from a finite bound-state orbital angular momentum. We discuss the quantum-confinement-induced interplay between bulk-material and orbital effects, which is nontrivial d

A VCO is implemented in an RF 90 nm CMOS process and covers the frequency range 2.55-4.08 GHz. Drawing 19 mA from 1.2 V, the phase noise at 20 MHz frequency offset from a 3.7 GHz carrier is -156 dBc/Hz, meeting the phase noise requirement for GSM/EDGE and SAW-less WCDMA transmitter after frequency division by 2 or by 4. A second version of the VCO covers an additional 4.90-5.75 GHz range, at the e

The problem of minimizing emissions of NO. and soot in a diesel engine using fuel injection timings and exhaust gas recirculation (EGR) valve position in a low-pressure EGR system as control variables is addressed. Two feedback variables are computed from in-cylinder pressure sensor data, the crank angle degree of 50 % fuel burnt, and the ignition delay. Empirical maps of NO, and soot according to

In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio

Selecting the appropriate analytical methods for characterizing the assembly and morphology of polymer-based vesicles, or polymersomes are required to reach their full potential in biotechnology. This work presents and compares 17 different techniques for their ability to adequately report size, lamellarity, elastic properties, bilayer surface charge, thickness and polarity of polybutadiene-polyet

System-on-chips (SOCs) and 3D stacked ICs are often tested for manufacturing defects in a modular fashion, enabling us to record the module test pass probability. We use this pass probability to exploit the abort-on-fail feature of automatic test equipment (ATE) and hence reduce the expected test time in the context of single-site testing. We present a model for calculation of expected test time,

A wireless body area network (WBAN) is a network of compact low power devices that are either wearable or implantable. A compact antenna with suitable radiation pattern and polarization is useful for WBAN applications. Ultra-Wideband (UWB) technology can be used in WBAN applications that require high data rates. This paper present a small wearable (15x17x17 mm) UWB antenna designed and optimized i

We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac

The Schrodinger operator on the half-line with periodic background potential perturbed by a certain potential of Wigner-von Neumann type is considered. The asymptotics of generalized eigenvectors for lambda is an element of C+ and on the absolutely continuous spectrum is established. The Weyl-Titchmarsh-type formula for this operator is proven.

Consider the transmission of complex-valued symbols over N parallell channels in additive white Gaussian noise. It is well known that linear precoding of the complex-valued data improves system performance (e. g. symbol error rate, information rate, MMSE, etc.) at a cost of increased decoding complexity at the receiver. This work constructs precoders that are constrained to have a decoding complex

This document describes the package CHIRON which includes two libraries, chironitself and jbnumlib. chiron is a set of routines useful for two-loop numerical results in chiral perturbation theory (ChPT). It includes programs for the needed one-and two-loop integrals as well as routines to deal with the ChPT parameters. The present version includes everything needed for the masses, decay constants

Aims. This work reports oscillator strengths for transitions of astrophysical interest in singly ionized rhodium. Methods. Seventeen radiative lifetimes in Rh+ have been measured with the time-resolved laser-induced fluorescence technique and combined with theoretical branching fractions calculated using a relativistic Hartree-Fock model including core-polarization effects to obtain oscillator str

Stratagems adopted by democratic leaders to try to insinuate, or anchor, a preferred course of action into the larger collective will have a variety of repercussions. Beyond the apparent success of the venture itself, the long-term integrity of the democratic fabric may be at stake if simmering rancour and discontent is left unheeded. These questions would seem particularly pertinent when studyi
