HDR Image Acquisition from Two LDR Images

open access: yesJournal of Broadcast Engineering, 2011
In this paper, we propose a scene adaptive method to obtain two LDR images with proper shutter speeds which capture the irradiance of scene effectively. The proposed method adaptively selects two shutter speeds across the video frame even when the illumination varies continuously.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Functional validation of a white pupae minimal gene construct in Ceratitis capitata (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
An intronless version of the white pupae (wp) gene was engineered to restore the wild type brown puparium color in white pupae phenotype mutants of the Mediterranean fruit fly, Ceratitis capitata. Functionality of the minimal gene version (mini‐wp) was verified in vivo, as one copy of mini‐wp successfully restored the wild type phenotype in homozygous ...

UV‐Induced Fluorescence in the Balance: Mate Choice and Predation Risk in the Female Ornamented Jumping Spiders

open access: yesIntegrative Zoology, EarlyView.
This study investigates the potential adaptive advantages of female‐specific UV‐induced fluorescence in male mate‐choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. Our findings provide empirical evidence of a trade‐off: While fluorescence enhances male mate preference, it ...

Peri‐operative pain management in major lower extremity amputation in vascular Surgery: a UK anaesthetic and vascular surgery Delphi consensus study*

open access: yesAnaesthesia, EarlyView.
Summary Introduction Major lower extremity amputations occurring secondary to vascular disease remain prevalent worldwide. Pain surrounding these procedures is complex, multifactorial and associated with poor functional and psychosocial outcomes. The evidence base informing pain management approaches in major lower extremity amputations remain largely ...

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

open access: yesArchaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...
