Gilles de la Tourette syndrome (GTS) is characterized by motor and phonic tics. It is unknown how paying attention to one's own tics might modulate tic frequency. We determined tic frequency in freely ticcing GTS patients while they were being filmed. In Study 1, we investigated 12 patients (1) alone ...

Primary alcohols are selectively converted into aldehydes by using a Nb2 O5 photocatalyst under visible-light irradiation. A strong interaction between the alcohol and Nb2 O5 generates a donor level within the forbidden band of Nb2 O5 , which provides a visible-light-harvesting ability. Over oxidation of aldehydes into carboxylic acids does ...

Many interventions have been implemented to improve hand hygiene compliance, each with varying effects and monetary costs. Although some previous studies have addressed the issue of conspicuousness, we found only 1 study that considered improving hand hygiene by using flashing lights. Our attention theory-based hypothesis tested whether a simple red ...

Alcohol hangover (AH) is a particular state after binge-like drinking. AH begins when ethanol is absent in plasma and is characterized by a cluster of physical and psychological symptoms. Alcohol disrupts circadian patterns of behavioral and physiological parameters; however, the involvement of circadian clock on the recovery of AH was ...

It has been firmly established that opening and closing the eyes strongly modulate the electro- and magnetoencephalography (EEG and MEG) signals acquired during wakeful rest. Certain features of the resting EEG are altered in chronic alcoholics and their offspring, and have been proposed as biomarkers for alcoholism. Spontaneous brain oscillations ...

Coffee (Coffea arabica L.) has been traditionally considered as shade-demanding, although it performs well without shade and even out-yields shaded coffee. Here we investigated how coffee plants adjust their metabolic machinery to varying light supply and whether these adjustments are supported by a reprogramming of the primary and secondary metabolism. ...

Abstract Conclusion: A positional nystagmus pattern compatible with a condition of a heavy cupula (cupulolithiasis) in the lateral semicircular canal could be reproduced in hemi-labyrinthectomized subjects during positional alcohol nystagmus 2 (PAN 2). The nystagmus pattern was opposite to that found in the same subjects during PAN 1. The affected ...

The purpose of the present studies was to examine the effects of response scale on the observed relationships between protective behavioral strategies (PBS) measures and alcohol-related outcomes. We reasoned that an "absolute frequency" scale (stem: "how many times …"; response scale: 0 times to 11+ times) conflates the frequency of ...

Exceptionally mild procedures for the visible light photocatalytic activation of selenoglycoside donors in the presence of alcohol acceptors have been developed. This process is demonstrated with both 1-phenylselenyl-2,3,4,6-tetra-O-benzyl glucoside (1) and 1-phenylselenyl-2,3,4,6-tetra-O-benzyl galactoside (2). Catalysis is effected with both metal (Ru(bpy)(3)) and organocatalysts (diphenyldiselenide). Reactions afford, in all cases, primarily ...

Human alcoholics display dramatic disruptions of circadian rhythms that may contribute to the maintenance of excessive drinking, thus creating a vicious cycle. While clinical studies cannot establish direct causal mechanisms, recent animal experiments have revealed bidirectional interactions between circadian rhythms and ethanol intake, suggesting that the chronobiological disruptions seen in ...

The integration of visual and auditory inputs in the human brain occurs only if the components are perceived in temporal proximity, that is, when the intermodal time difference falls within the so-called subjective synchrony range. We used the midpoint of this range to estimate the point of subjective simultaneity (PSS). ...

The misperception of vehicle approach speed is a key contributory factor to road traffic crash involvement. Past research has indicated that individuals use the rate of visual looming to calculate the time to passage (TTP) of a vehicle, and that smaller vehicles loom to a lesser extent than larger vehicles. ...

We reveal that slow-light enhanced optical forces between side-coupled photonic-crystal nanowire waveguides can be flexibly controlled by introducing a relative longitudinal shift. We predict that close to the photonic band edge, where the group velocity is reduced, the transverse force can be tuned from repulsive to attractive, and the force ...

Decreased melatonin production, due to acute suppression of pineal melatonin secretion by light exposure during night work, has been suggested to underlie higher cancer risks associated with prolonged experience of night work. However, the association between light exposure and melatonin production has never been measured in the field. In this ...

Accident rates for night sorties by helicopters traveling to offshore oil and gas platforms are at least five times higher than those during the daytime. Because pilots need to transition from automated flight to a manually flown night visual segment during arrival, the approach and landing phases cause great concern. ...

Circadian clocks regulate the adaptation of the organisms' physiology to the environmental light-dark cycles. Photic resetting of the clock differs among plant species. In Arabidopsis thaliana, morning-phased genes are not responsive to light signals at night, while in Phaseolus vulgaris, morning-phased genes are responsive to light at trough phases that ...

This study investigated how acute alcohol intake affects contrast processing mediated by inferred magnocellular (MC) and parvocellular (PC) pathways. Achromatic contrast discrimination thresholds were measured in 16 young healthy participants using a steady-pedestal, pulsed-pedestal or pedestal-Δ-pedestal paradigm designed to favor the inferred MC or the PC pathway. Each participant completed ...

We present a method to efficiently sort orbital angular momentum (OAM) states of light using two static optical elements. The optical elements perform a Cartesian to log-polar coordinate transformation, converting the helically phased light beam corresponding to OAM states into a beam with a transverse phase gradient. A subsequent lens ...
