Wearable sensors in paediatric neurology

Developmental Medicine &Child Neurology, EarlyView.
Types of signals monitored in children's natural environments using wearable sensors, and their associated applications in various paediatric neurological conditions. Plain language summary: https://onlinelibrary.wiley.com/doi/10.1111/dmcn.16267 Abstract Wearable sensors have the potential to transform diagnosis, monitoring, and management of children ...

Modeling vertical structure in circular velocity of spiral galaxy NGC 4244

, 2015
We study the vertical gradient in azimuthal velocity of spiral galaxy NGC 4244 in a thin disk model. With surface density accounting for the rotation curve, we model the gradient properties in the approximation of quasi-circular orbits and find the ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

Meteoritics &Planetary Science, EarlyView.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Diverse Rotation Curves of Galaxies in a Simulated Universe: the Observed Dependence on Stellar Mass and Morphology Reproduced [PDF]

ApJ 982, 11 (2025)
We use the IllustrisTNG cosmological hydrodynamical simulation to study the rotation curves of galaxies in the local universe. To do that, we first select the galaxies with 9.4 $<$ $\log{(M_\mathrm{star}/M_\odot)}$ $<$ 11.5 to make a sample comparable to that of SDSS/MaNGA observations.

On the axisymmetric thin disk model of flattened galaxies

, 2008
Non-monotonic features of rotation curves, and also the related gravitational effects typical of thin disks -- like backward-reaction or amplification of rotation by negative surface density gradients -- which are characteristic imprints of disk-like ...

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction

Meteoritics &Planetary Science, EarlyView.
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Flummoxing expectations

Noûs, EarlyView.
Abstract Expected utility theory often falls silent, even in cases where the correct rankings of options seems obvious. For instance, it fails to compare the Pasadena game to the Altadena game, despite the latter turning out better in every state. Decision theorists have attempted to fill these silences by proposing various extensions to expected ...

Extension of the C star rotation curve of the Milky Way to 24 kpc

, 2012
Demers and Battinelli published, in 2007 the rotation curve of the Milky Way based on the radial velocity of carbon stars outside the Solar circle. Since then we have established a new list of candidates for spectroscopy.

Validity of non‐traditional measures of obesity compared to total body fat across the life course: A systematic review and meta‐analysis

Obesity Reviews, EarlyView.
Summary IntroductionTraditional obesity measures including body mass index, waist circumference, waist‐to‐hip ratio, and waist‐to‐height ratio have limitations. The primary objective of this study was to identify and review the validity of non‐traditional obesity measures, using measures of total body fat as the reference standard, that have been used ...

Dark matter and rotation curves of stars in galaxies [PDF]

Astronomische Nachrichten, 2001
The dark matter accretion theory (around a central body) of the author on the basis of his 5-dimensional Projective Unified Field Theory (PUFT) is applied to the orbital motion of stars around the center of the Galaxy. The departure of the motion from Newtonian mechanics leads to approximately flat rotation curves being in rough accordance with the ...
