Conservation genomics of Pecos pupfish (Cyprinodon pecosensis)

Journal of Fish Biology, EarlyView.
Abstract The Pecos pupfish, Cyprinodon pecosensis, is an imperilled freshwater fish found in arid regions of Texas and New Mexico (USA). The species faces multiple challenges to persistence including reductions in suitable habitat, water shortages, as well as hybridization and competition with an introduced congener (sheepshead minnow, C.

Global modes and nonlinear analysis of inverted-flag flapping [PDF]

, 2017
An inverted flag has its trailing edge clamped and exhibits dynamics distinct from that of a conventional flag, whose leading edge is restrained. We perform nonlinear simulations and a global stability analysis of the inverted-flag system for a range of ...

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

The onset of unsteadiness of two-dimensional bodies falling or rising freely in a viscous fluid: a linear study [PDF]

, 2011
We consider the transition between the steady vertical path and the oscillatory path of two-dimensional bodies moving under the effect of buoyancy in a viscous fluid.

Fracture resistance and behavior of endodontically treated maxillary premolars with varying ferrule heights and post numbers: A laboratory study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure. Materials and Methods Twenty‐four extracted endodontically treated human maxillary first premolars were divided into three ...

Numerical Investigation on the Effect of Passive Jet Control on the Performance of a Vortex Induced Vibration Energy Harvester System

Energies
The present study investigates the effect of the passive jet control system on the performance of a vibration energy harvester system (VIVEHS). The shape of a bluff body plays a crucial role in determining the vortex shedding mechanism, while the passive

The Cross and Conflict: How Do Christians Impact Protest Dynamics?

Journal for the Scientific Study of Religion, EarlyView.
ABSTRACT This study examines the relationship between Christian actors, practices, and sacred sites in US protests and demonstrations, focusing on how political ideology shapes conflict outcomes. Using event‐level data from the Armed Conflict Location & Event Data Project (ACLED), the analysis explores 63,000 protest events from 2020 to 2024 ...
