For a sensor, high sensitivity, structural simplicity, and longevity are highly desired for measurement of salinity in seawater. This work proposed an ultrahigh sensitive photonic crystal fiber (PCF) salinity sensor based on the sagnac interferometer (SI). The propagation characteristics of the proposed PCF are analyzed by the finite element method (FEM). The achieved sensitivity reaches up to 37,500 ...

Introduction - In traditional East Asian Medicine (TEAM), various systems of practice exist that have used different theories to guide their practice. Although data gathering has been limited to what can be observed by the four examinations - si zhen, the different systems of practice have focused on different observational data to make diagnostic decisions and choose corresponding treatments. The ...

A new species Brachypogon (Isohelea) surma sp. n., with unique, leaf-like parameres, is described from Finnish Lapland based on males. Illustrations and COI sequences of this species are also provided. Females and males of Brachypogon (I.) singularis (Santos Abreu, 1918) from the Canary Islands are redescribed, a neotype is designated, and Ceratolophus rufigastris Santos Abreu, 1918 and Ceratolophus ...

Objective: To examine the prevalence of white matter hyperintensities (WMHs) in patients with traumatic brain injury (TBI) as compared to healthy controls, and to investigate whether there is an association between WMH lesion burden and performance on neuropsychological tests in patients with TBI.<p> <p>Methods: A total of 59 patients with TBI and 27 age- and gender-matched healthy controls ...

High energy protons accelerated during solar proton events (SPEs) can access the Earth's middle atmosphere at high and middle latitudes causing large‐scale ionization and chemical changes. In this study, we have compared the performance of two cutoff latitude models that predict the limit of the SPE impact area in the atmosphere during 73 SPEs from 1997 to 2010. We use observations from 13 riometer ...

The underlying neural mechanisms of transcranial direct current stimulation (tDCS), especially beyond the primary motor cortex, remain unclear. Several studies examined tDCS effects on either functional activity, neurotransmitters or behavior but few investigated those aspects together to reveal how the brain responds to tDCS. The objective is to elucidate the underlying mechanisms of tDCS using a ...

Ancient DNA has significantly improved our understanding of the evolution and population history of extinct megafauna. However, few studies have used complete ancient genomes to examine species responses to climate change prior to extinction. The woolly rhinoceros (<i>Coelodonta antiquitatis</i>) was a cold-adapted megaherbivore widely distributed across northern Eurasia during the Late Pleistocene ...

Recent discoveries of high levels of biological activity in the Arctic marine ecosystems during the polar night raise questions regarding the ecophysiology of the pelagic postlarval daubed shanny Leptoclinus maculatus. Of special interest is the composition of the lipid sac—a unique feature not found in other Arctic fishes. Analysis of the fatty acid content of major classes of lipids as membrane—total ...

I denne artikkelen studerer vi hvordan bruk av indirekte kommunikasjonsformer (nettbaserte) utfordrer lederoppgavene i kunnskapsorganisasjoner. Mer konkret er vi opptatte av å studere om fjernledelse medfører en vridning fra relasjonsorientert ledelse til oppgaveorientert ledelse, det vil si styring. Vår problemstilling er: Hvordan brukes sosiale medier ved fjernledelse? Utgangspunktet er to ...

The rapid embracing of artificial intelligence in psychiatry has a flavor of being the current “wild west”; a multidisciplinary approach that is very technical and complex, yet seems to produce findings that resonate. These studies are hard to review as the methods are often opaque and it is tricky to find the suitable combination of reviewers. This issue will only get more complex in the absence ...
