Latent Primary Papillary Microtumor in Thyroglossal Duct Cyst Wall - A Rare Case Report with Review of Literature [PDF]

National Journal of Laboratory Medicine, 2013
Thyroglossal duct cyst (TDC) is a common congenital midline neck mass. Generally TDCs are benign and incidence of malignancy in TDC is less than 1%. Majority of the tumors arise from thyroid remnants in the wall of the cyst and the common histologic ...

Mechanism Analysis of Time-Dependent Characteristic of Dynamic Errors of Machine Tools

Machines, 2022
The Dynamic Errors (DEs) of individual axes present Time-dependent Characteristics (TDCs) because the setpoints, as the input of the servo feed system, change in velocity, acceleration and jerk during the feed motion.

The Uncertain Outcome of Prefrontal tDCS [PDF]

Brain Stimulation, 2014
Transcranial direct current stimulation (tDCS) is increasingly used in research and clinical settings, and the dorsolateral prefrontal cortex (DLPFC) is often chosen as a target for stimulation. While numerous studies report modulation of cognitive abilities following DLPFC stimulation, the wide array of cognitive functions that can be modulated makes ...

Sleep Fosters Odor Recognition in Children with Attention Deficit Hyperactivity Disorder but Not in Typically Developing Children

Brain Sciences, 2022
Prior experience represents a prerequisite for memory consolidation across various memory systems. In the context of olfaction, sleep was found to enhance the consolidation of odors in adults but not in typically developing children (TDC), likely due to ...

Polyurethane Depolymerization With Alkyl, Aryl, and Mixed Carbonates. [PDF]

ChemSusChem
The depolymerization of polyurethane foams strongly depends on carbonate structure. Aryl carbonates improve hard‐segment solubility but generate side products. Alkyl carbonates give cleaner products yet suffer from limited hard‐block solubility and require anisole as a cosolvent. Mixed carbonate systems balance these effects, improving solubility while

Preconditioning tDCS facilitates subsequent tDCS effect on skill acquisition in older adults [PDF]

Neurobiology of Aging, 2017
Functional motor declines that often occur with advancing age-including reduced efficacy to learn new skills-can have a substantial impact on the quality of life. Recent studies using noninvasive brain stimulation indicate that priming the corticospinal system by lowering the threshold for the induction of long-term potentiation-like plasticity before ...
