Animals are thought to use achromatic signals to detect small (or distant) objects and chromatic signals for large (or nearby) objects. While the spatial resolution of the achromatic channel has been widely studied, the spatial resolution of the chromatic channel has rarely been estimated. Using an operant conditioning method, we determined (i) the achromatic contrast sensitivity function and (ii)

This study examines the influences of national contexts on crisis attribution to address the recent appeal for a more contextually sensitive perspective in crisis communication research. Specifically, this study revisits the Situational Crisis Communication Theory (SCCT) in the Chinese context by taking an online discussion on Weibo about a high-profile homicide in a McDonald’s restaurant as the c

Studies on risk factors for penile intraepithelial neo-plasia have been small in size, have not distinguished penile intraepithelial neoplasia from invasive cancer, and have relied on self-reported information. This study investigated risk factors for penile intraepithelial neoplasia in a cohort of 580 penile intraepithelial neoplasia cases and 3,436 controls using information from 7 Swedish regis

Background: The mechanically expandable Lotus Valve System is a fully repositionable and retrievable valve with an adaptive seal to minimize paravalvular leak (PVL). The aim of this study was to evaluate the short- and long-term safety and efficacy of the new device with focus on a new implantation technique to reduce the need for a permanent pacemaker (PPM) post procedure. Methods: We performed

Climate change's effect on sea surface temperature (SST) at the regional scale vary due to driving forces that include potential changes in ocean circulation and internal climate variability, ice cover, thermal stability, and ocean mixing layer depth. For a better understanding of future effects, it is important to analyze historical changes in SST at regional scales and test prediction techniques

English Only in Multilingual Classrooms? A Study of Students’ Self-Reported Practices and Attitudes. A pressing issue in multilingual education is when to draw on students’ multilingual repertoires to enhance learning and promote equity (Cummins 2017; Kramsch 2009). Classroom research in L2 learning supports multilingual/translanguaging practices (e.g. Lee & Macaro 2013; Zhang 2018), but much

We propose the use of a quantum thermal machine for low-temperature thermometry. A hot thermal reservoir coupled to the machine allows for simultaneously cooling the sample while determining its temperature without knowing the model-dependent coupling constants. In its most simple form, the proposed scheme works for all thermal machines that perform at Otto efficiency and can reach Carnot efficien

Carbon storage dynamics in vegetation and soil are determined by the balance of carbon influx and turnover. Estimates of these opposing fluxes differ markedly among different empirical datasets and models leading to uncertainty and divergent trends. To trace the origin of such discrepancies through time and across major biomes and climatic regions, we used a model-data fusion framework. The framew

Directed relation graph with error propagation (DRGEP) method combined with extensive validation for 0D, 1D and 2D CFD modeling supported by sensitivity and Rate-Of-Production (ROP) analyses are implemented for comparative study of detailed and reduced kinetic mechanisms for CH 4 + H 2 combustion. To this end, two detailed kinetic mechanisms, namely AramcoMech 2.0 and recently updated Konnov me

The Baltic Sea is one of the most eutrophied seas in the world, facing challenges with both hypoxia and algae blooms. In this study we analyse the effect of using different fishery policy instruments to reduce nutrient loads by removing fish biomass from the ecosystem. The study covers Danish, Finnish and Swedish pelagic fisheries. We distinguish between a private optimum maximising the net presen

Models suggest that climate change mitigation now depends on negative emissions, i.e. the large‐scale removal of carbon dioxide from the atmosphere. This assumption has been criticised in the climate policy literature for being unfeasible and unjust. This article asks how critical scholars can make sense of, and contribute to these debates. It suggests that negative emissions can be conceived of a

Endocrine disorders that lead to a state of chronic high blood glucose levels are collectively referred to as diabetes. This metabolic disease is mainly categorized into type 1 (T1D) and type 2 diabetes (T2D). These diabetic forms originate from distinct triggering environmental, genetic, and altered mechanisms. T2D is a consequence of metabolic load, peripheral insulin resistance, and failure of

Atmospheric new particle formation (NPF) is a common phenomenon all over the world. In this study we present the longest time series of NPF records in the eastern Mediterranean region by analyzing 10 years of aerosol number size distribution data obtained with a mobility particle sizer. The measurements were performed at the Finokalia environmental research station on Crete, Greece, during the per

Mexico has the most transited migratory corridor in the world . The complex migratory flows transiting the country—mainly Mexican, Central and South Amer- ican—have historically been perceived as economic and male . Scholars have not- ed as problematic the categorisation of the ‘labour migrant’ as being exclusive- ly voluntary. It has been demonstrated that framing agency through simplified unders

Objective: Long-term oxygen therapy (LTOT) during 15 h/day or more prolongs survival in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia. No randomized controlled trial has evaluated the net effects (benefits or harms) from LTOT 24 h/day compared with 15 h/day or the effect in conditions other than COPD. We describe a multicenter, national, phase IV, non-superiority,

The high-pressure homogenizer (HPH) is used extensively in the processing of non-solid foods. Food researchers and producers use HPHs of different scales, from laboratory-scale (∼10 L/h) to the largest production-scale machines (∼50 000 L/h). Hence, the process design and interpretation of academic findings regarding industrial condition requires an understanding of differences between scales. Thi
