Gazing into spatiotemporal ‘known unknowns’: the influence of uncertainty on pupil size and saccadic eye movements

Scientific Reports
Expectation of a future stimulus increases the preparedness to act once it actually appears and results in reduced latency of the appropriate motor response.

Growth conditions, structure, and superconductivity of pure and metal-doped FeTe1-xSex single crystals

, 2012
Superconducting single crystals of pure FeTe1 xSex and FeTe0.65Se0.35 doped with Co, Ni, Cu, Mn, Zn, Mo, Cd, In, Pb, Hg, V, Ga, Mg, Al, Ti, Cr, Sr or Nd into Fe ions site have been grown applying Bridgman's method. It has been found that the sharpness of

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Neural representation of the musical beat is facilitated but not contingent on the repetition of rhythmic patterns

Scientific Reports
Music often entails perception of periodic beats which serve as internal temporal references to coordinate movements to music. Crucially, beat perception arises even in syncopated musical rhythms, which only weakly cue the beat periodicity.

Mid-infrared emissions of Dy3+ ions in CaF2 [PDF]

EPJ Web of Conferences
We report on a comprehensive spectroscopic study of singly Dy3+ doped and Er3+,Dy3+ codoped calcium fluoride (CaF2) crystals for mid- infrared laser applications. The f-f transition probabilities of Dy3+ were determined by the Judd-Ofelt theory.

Electromagnetic modulation of monochromatic neutrino beams

, 2015
A possibility to produce a modulated monochromatic neutrino beam is discussed. Monochromatic neutrinos can be obtained in electron capture by nuclei of atoms or ions, in particular, by nuclei of hydrogen-like ions. It is shown that monochromatic neutrino

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Neural substrates underlying motor skill learning in chronic hemiparetic stroke patients

Frontiers in Human Neuroscience, 2015
Motor skill learning is critical in post-stroke motor recovery, but little is known about its underlying neural substrates. Recently, using a new visuomotor skill learning paradigm involving a speed/accuracy trade-off in healthy individuals we identified

Helium-3 and Helium-4 acceleration by high power laser pulses for hadron therapy

, 2015
The laser driven acceleration of ions is considered a promising candidate for an ion source for hadron therapy of oncological diseases. Though proton and carbon ion sources are conventionally used for therapy, other light ions can also be utilized ...

Ion/ion chemistry of high-mass multiply charged ions [PDF]

Mass Spectrometry Reviews, 1998
Electrospray ionization has enabled the establishment of a new area of ion chemistry research based on the study of the reactions of high-mass multiply charged ions with ions of opposite polarity. The multiple-charging phenomenon associated with electrospray makes possible the generation of multiply charged reactant ions that yield charged products as ...
