Temporally Dense Ray Tracing

We present a technique for real-time ray tracing with the goal of reaching 240 frames per second or more. The core idea is to trade spatial resolution for faster temporal updates in such a way that the display and human visual system aid in integrating high-quality images. We use a combination of frameless and interleaved rendering concepts together with ideas from temporal antialiasing algorithmsWe present a technique for real-time ray tracing with the goal of reaching 240 frames per second or more.

EDGE: from quiescent to gas-rich to star-forming low-mass dwarf galaxies

We study how star formation is regulated in low-mass field dwarf galaxies (⁠105≤M⋆≤106M⊙⁠), using cosmological high-resolution (⁠3pc⁠) hydrodynamical simulations. Cosmic reionization quenches star formation in all our simulated dwarfs, but three galaxies with final dynamical masses of 3×109M⊙ are subsequently able to replenish their interstellar medium by slowly accreting gas. Two of these galaxie

Developmental Citizenship, Symbolic Landscapes, and Transformation in China and South Korea

Despite glaring differences between South Korean and Chinese societies, South Korea offers an instructive reference point when thinking about developmental citizenship in China. Experiences of mobilization, albeit distinct in each country, inform the sorts of symbols that bring people together for resistance against or compliance with authority. The concept of developmental citizenship, besides dr

Authoritarian Legality after Authoritarianism : Legal Governance of Parties and Elections before and after Democratic Transition in South Korea

The Republic of Korea (ROK) was designed as a Cold War democracy. It started as an electoral regime with formal commitments to democratic values, but institutions designed to keep the state secure also imposed limits on domestic political struggle. From the ROK’s founding in 1948 to the political liberalization of 1987, the political system shifted between orders that might be labeled more democra

More than Anti-communism : Electoral Politics and the Meanings of Democracy in Taiwan

Governments across anti-communist Asia, with US backing or tacit consent, devised institutions and practices for marginalising popular forces. Such internalisation of the Cold War involved measures ranging from violence and ideological mobilisation to disciplinary modes of control. With democratisation, Cold War devices for domestic control could remain entrenched or be rolled back. Examining the

Surface-modified nanoerythrosomes for potential optical imaging diagnostics

Nanoerythrosomes (NERs), vesicle-like nanoparticles derived from red blood cells, represent a new and interesting vector for therapeutic molecules and imaging probes, mainly thanks to their high stability and excellent biocompatibility. Aiming to present a proof-of-concept of the use of NERs as diagnostic tools for in vitro/in vivo imaging purposes, we report here several functionalization routes

The coordinated outcome of STIM1-Orai1 and superoxide signalling is crucial for headkidney macrophage apoptosis and clearance of Mycobacterium fortuitum

The mechanisms underlying M. fortuitum-induced pathogenesis remains elusive. Using headkidney macrophages (HKM) from Clarias gariepinus, we report that TLR-2-mediated internalization of M. fortuitum is imperative to the induction of pathogenic effects. Inhibiting TLR-2 signalling alleviated HKM apoptosis, thereby favouring bacterial survival. Additionally, TLR-2-mediated cytosolic calcium (Ca2+)c

Circular business model experimentation : Demystifying assumptions

Circular business model experiments may help firms transition towards a circular economy. Little is known about how the participants of experimentation – entrepreneurs, intrapreneurs, innovation managers – develop and test their assumptions during the experimentation process to achieve more circular outcomes. Using a design-science approach, we investigate this process and develop principles to im

Biochar increases soil microbial biomass but has variable effects on microbial diversity : A meta-analysis

Biochar has been extensively studied as a soil amendment for carbon sequestration and for improving soil quality; however, a systematic understanding of the responses of soil microbial biomass and diversity to biochar addition is lacking. Here, a meta-analysis of 999 paired data points from 194 studies shows that biochar increases microbial biomass but has variable effects on microbial diversity.

Farmer's behavior in pesticide use : Insights study from smallholder and intensive agricultural farms in Bangladesh

Since independence and over the years, pesticides have become a dominant feature of Bangladesh agriculture. To protect farmers' health, environment and to improve sustainability of chemical pest control quantitative understanding of farmers' behavior in pesticide use is critical. However, study on the levels of knowledge and awareness of farmers and the practices of pesticide use are often limited

STAT3 inhibition with galiellalactone effectively targets the prostate cancer stem-like cell population

Cancer stem cells (CSCs) are a small subpopulation of quiescent cells with the potential to differentiate into tumor cells. CSCs are involved in tumor initiation and progression and contribute to treatment failure through their intrinsic resistance to chemo- or radiotherapy, thus representing a substantial concern for cancer treatment. Prostate CSCs’ activity has been shown to be regulated by the

Light current-voltage measurements of single, as-grown, nanowire solar cells standing vertically on a substrate

Nanowire based solar cells hold promise for terrestrial and space photovoltaic applications. However, to speed-up and further continue with nanowire solar cell development, quick and reliable characterization tools capable of evaluating single nanowire performance of nanowires still standing on the substrate are necessary. Here, we present the use of a light emitting diode (LED) based setup, which

Traumatic and non-traumatic bone marrow edema in ankle MRI : a pictorial essay

Bone marrow edema (BME) is one of the most common findings on magnetic resonance imaging (MRI) after an ankle injury but can be present even without a history of trauma. This article will provide a systematic overview of the most common disorders in the ankle and foot associated with BME. The presence of BME is an unspecific but sensitive sign of primary pathology and may act as a guide to correct
