Acute mountain sickness: the "poison of the pass" [PDF]

open access: yesWestern Journal of Medicine, 2000
Few sights are more breathtaking and inspirational than a mountain peak. Yet, behind the innocence and majesty of one of nature's wonders lies a sleeping evil, acute mountain sickness (AMS). The constellation of symptoms that characterizes AMS is a frequent cause of morbidity and occasionally mortality and affects 25% of travelers sojourning to ...

Ex‐Ante Assessment of Farm Resilience to Institutional Shocks: A Modeling Approach

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using the agent‐based model SWISSland, we simulate farm‐level responses and interactions under two institutional shocks: tariff reductions and direct payment reductions. Using a framework we developed, we assess resilience capacities, resilience attributes, and the provision of private and public goods, following the shock.

Phylogenomic insights into the genus Tulipa (Liliaceae): Taxonomy, evolution, and biogeography

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Tulips are one of the best‐known geophytes, but their taxonomy remains convoluted and their evolutionary history poorly understood. Here, we used plastid genomes to identify some issues with current classification, understand the diversification history of the genus, and identify potential species linked to historical cultivation ...

Existence and multiplicity of solutions for divergence type elliptic equations

open access: yesElectronic Journal of Differential Equations, 2011
We establish the existence and multiplicity of weak solutions of a problem involving a uniformly convex elliptic operator in divergence form. We find one nontrivial solution by the mountain pass lemma, when the nonlinearity has a $(p-1)$-superlinear ...

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Existence and multiplicity of nontrivial solutions for poly-Laplacian systems on finite graphs

open access: yesBoundary Value Problems, 2022
In this paper, we investigate the existence and multiplicity of nontrivial solutions for poly-Laplacian system on a finite graph G = ( V , E ) $G=(V, E)$ , which is a generalization of the Yamabe equation on a finite graph.

Temperature‐Controlled Radiofrequency for Severe Nasal Airway Obstruction: A Non‐Inferiority Comparison With Surgical Intervention

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Temperature‐controlled radiofrequency (TCRF), septoplasty (ST) with turbinate reduction, and functional rhinoplasty (FR) are treatment options for nasal airway obstruction (NAO) and nasal valve dysfunction (NVD), but no direct comparison of these procedures has been performed. Methods This prospective, open‐label, non‐inferiority (

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained
