Bird Strike Risk for Space Launch Vehicles [PDF]

open access: yes, 2017
Within seconds after liftoff of the Space Shuttle during mission STS-114, a turkey vulture impacted the vehicle's external tank. The contact caused no apparent damage to the shuttle, but the incident led NASA to consider the potential consequences of ...

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.

Virtual vs. Standard Strike: An Experiment [PDF]

open access: yes
In this paper we compare - in the laboratory - stoppage and virtual strike. Our experiment confirms that higher wages offered by an employer lead to considerably more costly effort provision.

Monthly or menstrual? A scoping review of catamenial epilepsy and non‐menstrual seizure rhythms

open access: yesEpilepsia, EarlyView.
Abstract Objective Despite the reported high prevalence of catamenial epilepsy (CE), the condition remains poorly defined, with lack of consensus on what entails a menstrual‐related seizure exacerbation. Emerging evidence of multiday cycles of seizure activity, including about‐monthly cycles, present in both men and women, further confound the ...

Bird Strike Prevention - An Operational Approach

open access: yes, 2019
Current bird strike prevention at airports is performed by wildlife control units and concentrates mainly on keeping birds from the perimeter. This research paper focuses on an approach for procedural bird strike prevention involving pilots and air ...

Improved Power Tracking and Performance Evaluation Using a Tri‐Meta Hybrid DOA–CSA–WOA‐Based MPPT Controller for Standalone PV System

open access: yesEnergy Science &Engineering, EarlyView.
A Tri‐Meta Hybrid DOA–CSA–WOA Maximum Power Point Tracking controller is developed to enhance photovoltaic system performance. The proposed approach achieves higher tracking efficiency, faster convergence, and robust operation under dynamic irradiance and partial shading conditions.

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

open access: yesGeological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Must Longtermists Wish Us All Dead? A Quadrilemma

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...
