iTRAQ-Based Quantitative Protein Expression Profiling and MRM Verification of Markers in Type 2 Diabetes

iTRAQ-Based Quantitative Protein Expression Profiling and MRM Verification of Markers in Type 2 Diabetes

The pathogenesis of Type 2 diabetes mellitus (T2DM) is complex owing to molecular heterogeneity in the afflicted population. Current diagnostic methods rely on blood glucose measurements, which are noninformative with respect to progression of the disease to other associated pathologies. Thus, predicting the risk and development of T2DM-related complications, such as cardiovascular disease, remains a major challenge.

Speed Sensorless Induction Motor Drive With Predictive Current Controller

Speed Sensorless Induction Motor Drive With Predictive Current Controller

Today, speed sensorless modes of operation are becoming standard solutions in the area of electric drives. This paper presents a speed sensorless control system of an induction motor with a predictive current controller.

Quantum resources for hybrid communication via qubit-oscillator states

Quantum resources for hybrid communication via qubit-oscillator states

We investigate a family of qubit-oscillator states as resources for hybrid quantum communication. They result from a mechanism of qubit-controlled displacement on the oscillator. For large displacements, we obtain analytical formulas for entanglement and other nonclassical correlations, such as entropic and geometric discord, in those states.

Intervention in biological phenomena modeled by S-systems

Intervention in biological phenomena modeled by S-systems

Recent years have witnessed extensive research activity in modeling biological phenomena as well as in developing intervention strategies for such phenomena. S-systems, which offer a good compromise between accuracy and mathematical flexibility, are a promising framework for modeling the dynamical behavior of biological phenomena. In this paper, two different intervention strategies, namely direct and indirect, are proposed for the S-system model.

Inverse spectral problems for differential operators on arbitrary compact graphs

Inverse spectral problems for differential operators on arbitrary compact graphs

Inverse problems of spectral analysis are studied for Sturm-Liouville differential operators on arbitrary compact graphs. The uniqueness of recovering operators from their spectra is proved, and a constructive procedure for the solution of this class of inverse problems is provided.

Enhanced compressive response of hybrid Mg-CNT nano-composites

Enhanced compressive response of hybrid Mg-CNT nano-composites

Uniaxial compressive properties of hybrid Mg/Al–CNT nano-composites are studied in the present paper. Hybrid nano-composites were fabricated using powder metallurgy route followed by microwave assisted rapid sintering technique and hot extrusion.

Joint rate, power, and decoding order optimization of multiuser MIMO systems

Joint rate, power, and decoding order optimization of multiuser MIMO systems

We consider multiuser MIMO systems with some of the users having target-rate requirements while the other users are working on best-effort data transmission. Both multiple-access channels (MAC) and broadcast channels (BC) are considered.
Subwavelength optical lattices induced by position-dependent dark states

Subwavelength optical lattices induced by position-dependent dark states

A method for the generation of subwavelength optical lattices based on multilevel dark states is proposed. The dark state is formed by a suitable combination of standing wave light fields, leading to position-dependent populations of the ground states.
Inversion of three-stage stress–strain relation for stainless steel in tension and compression

Inversion of three-stage stress–strain relation for stainless steel in tension and compression

Presented in this paper is a new stress–strain relation for stainless steel alloys that provides the stress as an explicit function of the strain. The relation is an approximate inversion of a recently proposed three-stage stress–strain relation based on a modified Ramberg–Osgood equation. The three-stage relation is a much more accurate formulation than the previous two-stage formulations and is applicable to both tensile as well as compressive stresses.
