A 2+1+1 quadruple star system containing the most eccentric, low-mass, short-period, eclipsing binary known [PDF]

, 2021
We present an analysis of a newly discovered 2+1+1 quadruple system with TESS containing an unresolved eclipsing binary (EB) as part of TIC 121088960 and a close neighbor TIC 121088959. The EB consists of two very low-mass M dwarfs in a highly-eccentric ($e$ = 0.709) short-period ($P$ = 3.04358 d) orbit. Given the large pixel size of TESS and the small

Correlation between premonitory urges and tic symptoms in a Chinese population with tic disorders

Pediatric Investigation, 2020
Importance Tics usually start around 4–6 years old and affect about 1% of school‐age children. Premonitory urges (PUs) are sensory phenomena that precede tics and are often described as unpleasant feelings. Recent evidence supports a relationship between

Cytokine levels reflect tic symptoms more prominently during mild phases

BMC Neuroscience, 2023
Tic disorder is a neuropsychiatric condition that affects 3% of all children and can have a significant impact on their quality of life. Cytokines, interferons, interleukins, lymphokines, and tumor necrosis factors are involved in the neuroinflammatory ...

Electronic structure and chemical bonding of nc-TiC/a-C nanocomposites [PDF]

Phys. Rev. B 80, 235108 (2009), 2011
The electronic structure of nanocrystalline (nc-) TiC/amorphous C nanocomposites has been investigated by soft x-ray absorption and emission spectroscopy. The measured spectra at the Ti 2p and C 1s thresholds of the nanocomposites are compared to those of Ti metal and amorphous C.

The Pharmacologic Treatment of Tic Disorders

Child and Adolescent Psychiatric Clinics of North America, 1995
The approach to treating children and adolescents with tic disorders has evolved in recent years such that complete elimination of tics is no longer the primary goal of treatment. Indeed, given the high frequency of psychiatric comorbidity in TS, treatment planning begins with identification of target symptoms.

Pilot Testing Behavior Therapy for Chronic Tic Disorders in Neurology and Developmental Pediatrics Clinics [PDF]

, 2015
Comprehensive Behavioral Intervention for Tics (CBIT) is an efficacious treatment with limited regional availability. As neurology and pediatric clinics are often the first point of therapeutic contact for individuals with tics, the present study ...

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Interrogating the Genetic Determinants of Tourette’s Syndrome and Other Tic Disorders Through Genome-Wide Association Studies [PDF]

, 2019
Objective: Tourette’s syndrome is polygenic and highly heritable. Genome-wide association study (GWAS) approaches are useful for interrogating the genetic architecture and determinants of Tourette’s syndrome and other tic disorders. The authors conducted

Time is ticking for TikTok tics: A retrospective follow‐up study in the post‐COVID‐19 isolation era

Brain and Behavior
Introduction During the COVID‐19 pandemic, an influx of adolescents presented worldwide with acute onset of functional tic‐like behaviors (FTLBs). Our goal was to evaluate psychosocial factors around onset, to elucidate outcomes after pandemic isolation ...

Combining X‐Ray Photoelectron and Absorption Spectroscopies for Determining Surface Chemistry and Composition of Ti3C2Tx MXene

Advanced Materials Interfaces, EarlyView.
The surface chemistry and core composition of Ti3C2Tx MXenes is often derived from X‐ray Photoelectron Spectroscopy (XPS) but its determination and quantification remain difficult due to adsorbed species such as adventitious carbon. This challenge is overcome by using energy‐dependent XPS and depth profile modeling of the Ti3C2Tx MXene surface ...
