Expression of Immunohistochemical Markers (CD56 and P63) in Various Non-Neoplastic and Neoplastic Lesions of Thyroid Gland [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2020
Introduction: Thyroid disorders are very common all over India, more so in Kerala. Although definite histologic criteria exist for diagnosing various thyroid lesions, there is an overlap of many nuclear and cytoplasmic features like nuclear atypia ...

Spin currents and spin dynamics in time-dependent density-functional theory [PDF]

open access: yes, 2001
We derive and analyse the equation of motion for the spin degrees of freedom within time-dependent spin-density-functional theory (TD-SDFT). Results are (i) a prescription for obtaining many-body corrections to the single-particle spin currents from the ...

A Novel Strategy Based on Linear Active Disturbance Rejection Control for Harmonic Detection and Compensation in Low Voltage AC Microgrid

open access: yesEnergies, 2019
In an AC microgrid, harmonic distortion is mainly caused by power electronic equipment and nonlinear loads. In this paper, linear active disturbance rejection control (LADRC) is used to control the fundamental current at the point of common coupling (PCC)

Time-dependent bond-current functional theory for lattice Hamiltonians: fundamental theorem and application to electron transport [PDF]

open access: yes, 2011
The cornerstone of time-dependent (TD) density functional theory (DFT), the Runge-Gross theorem, proves a one-to-one correspondence between TD potentials and TD densities of continuum Hamiltonians. In all practical implementations, however, the basis set

Functional Outcome in Children with Hirschsprung’s Disease after Modified Duhamel’s Procedure: A Longitudinal Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Introduction: The classical surgical treatment of Hirschsprung’s Disease (HD) is by resection of the aganglionic segment of the distal intestine and bringing down the ganglionic segment by Modified Duhamel’s procedure or other pull-through operations.

Universal Scaling of the Quantum Conductance of an Inversion-Symmetric Interacting Model [PDF]

open access: yes, 2010
We consider quantum transport of spinless fermions in a 1D lattice embedding an interacting region (two sites with inter-site repulsion U and inter-site hopping td, coupled to leads by hopping terms tc).

Visual search for basic emotional expressions in autism: impaired processing of anger, fear and sadness, but a typical happy face advantage [PDF]

open access: yes, 2010
Facial expression recognition was investigated in 20 males with high functioning autism (HFA) or Asperger syndrome (AS), compared to typically developing individuals matched for chronological age (TD CA group) and verbal and non-verbal ability (TD V/NV ...

Influence of chilled and frozen storage on the stability of trout and herring fillet [PDF]

open access: yes, 2006
Effects of chilled and frozen storage on specific enthalpy (ΔH) and transition temperature (Td) of protein denaturation as well as on selected functional properties of muscle tissue of rainbow trout and herring were investigated. The Td of myosin shifted

Pneumatic and Optical Characterization and Optimization of Hydrogen Injectors for Internal Combustion Engine Application

open access: yesFrontiers in Mechanical Engineering, 2022
To achieve future emission targets for internal combustion engines, the use of hydrogen gas generated by renewable energy sources (known as “green” hydrogen) instead of fossil fuels plays a key role in the development of new combustion-based engine ...
