Three contributions to Galaxy Dynamics: distant galaxy kinematics, mass, and M/L

open access: yes, 1998
1) Rotation Curves and M/L Evolution for Galaxies to z=0.4, (Bershady, Haynes, Giovanelli, & Andersen) 2) Mass Estimates of Starbursting Galaxies: Line Widths versus Near-IR Luminosities (Jangren, Bershady, & Gronwall) 3) Galaxy Kinematics with Integral Field Spectroscopy (Andersen, Bershady)

Non‐Negligible Influence of Forcing Mechanisms on Turbulent Mixing at Low Reynolds Numbers: A One‐Dimensional Turbulence Study

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT This study presents a numerical investigation of passive scalar mixing in homogeneous isotropic turbulence (HIT). Different volumetric forcing schemes have been used in the literature, but the side effects are rarely discussed, either because these are assumed irrelevant or because it is too costly to conduct such an analysis with a high ...

Kinematics of z~4-6 Lyman Break Galaxies in ALPINE

open access: yes, 2020
The past century has seen massive improvements in the study of galaxy kinematics. Early work focused on single nearby galaxies, while current studies probe the kinematics of many objects or single objects in greater detail.

A Dynamical and Kinematic Model of the Galactic Stellar Halo and Possible Implications for Galaxy Formation Scenarios [PDF]

open access: yesThe Astrophysical Journal, 1997
We re-analyse the kinematics of the system of blue horizontal branch field (BHBF) stars in the Galactic halo (in particular the outer halo), fitting the kinematics with the model of radial and tangential velocity dispersions in the halo as a function of galactocentric distance r proposed by Sommer-Larsen, Flynn & Christensen (1994), using a much ...

A Re‐Examination of Foundational Elements of Cosmology

open access: yesFortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

Stride‐to‐Stride Fluctuations and Temporal Patterns of Muscle Activity Exhibit a Stronger Relationship in Running‐Induced Fatigue

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT During gait, the temporal patterns of stride‐to‐stride fluctuations and muscle activation exhibit similar responses. This study examined if increasing task demands such as fatigued high intensity running affects this relationship. Eleven experienced runners completed two 400‐m runs (R1, R2) with a 3‐min break to induce fatigue.

Multiscale Convolutional–Bidirectional LSTM Fusion of Spatiotemporal Attention for Human Activity Recognition

open access: yesIET Biometrics, Volume 2026, Issue 1, 2026.
Human activity recognition (HAR) is a core technology in fields such as smart healthcare and human–computer interaction, which aims to classify daily activities (e.g., walking and running) based on sensor data automatically. While existing approaches achieve high accuracy in controlled laboratory settings, they often perform poorly in real‐world ...

OrchardQuant‐3D: combining drone and LiDAR to perform scalable 3D phenotyping for characterising key canopy and floral traits in fruit orchards

open access: yesPlant Biotechnology Journal, Volume 23, Issue 11, Page 4910-4929, November 2025.
Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, Volume 4, Issue 3, Page 382-405, September 2025.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
