Role of shocked accretion flows in regulating the QPO of galactic black hole candidates [PDF]

, 2003
Using a generalized non-spherical, multi-transonic accretion flow model, we analytically calculate the normalized QPO frequency ${\bar {\bf {\nu}}}_{qpo}$ of galactic black hole candidates in terms of dynamical flow variables and self-consistently study ...

Accident-tolerant hybrid ceramics for fusion breeding blanket

Materials & Design
In a water-cooled ceramic breeding blanket for fusion reactors, hydrogen gas generation by steam oxidation of metallic Be compounds (i.e. neutron multiplier) in a loss-of-coolant accident (LOCA) raises major safety concerns.

Inhibition of Return in the visual field [PDF]

, 2013
Inhibition of return (IOR) as an indicator of attentional control is characterized by an eccentricity effect, that is, the more peripheral visual field shows a stronger IOR magnitude relative to the perifoveal visual field.

Clinical, Genetic, and Imaging Characteristics of SCA27B: Insights from a Large Dutch Cohort

Movement Disorders, EarlyView.
Abstract Background Deep intronic GAA repeat expansions in intron 1 of the FGF14 gene were identified in 2023 as cause of late‐onset cerebellar ataxia. Since then, GAA‐FGF14‐related ataxia (SCA27B) has emerged as one of the most common genetic causes of late‐onset cerebellar ataxia.

A novel chemical reaction model for safety analysis of lithium–lead/water interaction in water cooled lithium lead breeding blankets using SIMMER code

Nuclear Fusion
The water cooled lithium lead breeding blanket (BB) stands out as one of the most promising designs for future fusion reactor BBs. However, the significant interaction between water and lithium–lead, particularly triggered by an In-Box LOCA (Loss of ...

The Use of Generalized Information Dimension in Measuring Fractal Dimension of Time Series

, 1998
An algorithm for calculating generalized fractal dimension of a time series using the general information function is presented. The algorithm is based on a strings sort technique and requires $O(N \log_2 N)$ computations. A rough estimate for the number

Critical current and stability effects between 0 and 6 tesla in mono and multifilamentary NbTi conductors having a CuNi matrix [PDF]

, 1985
We investigated the current carrying capacities of ten NbTi superconductors having a CuNi matrix with diameters between 50 and 300 ¿m as function of an applied magnetic field of 0 to 6 tesla.

Community science datasets identify the spatial occurrence and hotspots of flapper skate (Dipturus intermedius)

Journal of Fish Biology, EarlyView.
Abstract The flapper skate, Dipturus intermedius (Parnell, 1837), is a large‐bodied, slow‐growing and late‐maturing, Critically Endangered elasmobranch with a constrained population distribution. Here, we use two longitudinal community science datasets to investigate the occurrence of flapper skates in Irish waters. The two datasets are as follows: the

A gaze prediction technique for open signed video content using a track before detect algorithm [PDF]

, 2008
This paper proposes a gaze prediction model for open signed video content. A face detection algorithm is used to locate faces across each frame in both profile and frontal orientations. A grid-based likelihood ratio track before detect routine is used to
