Drell-Yan process in pA collisions : Path-integral treatment of coherence effects

In this work, we investigate production of Drell-Yan (DY) pairs in proton-nucleus collisions in kinematic regions where the corresponding coherence length does not exceed the nuclear radius, RA, and the quantum coherence effects should be treated with special care. The results for the nucleus-to-nucleon production ratio available in the literature so far are usually based on the assumption of a ve

Empirical genome evolution models root the tree of life

A reliable phylogenetic reconstruction of the evolutionary history of contemporary species depends on a robust identification of the universal common ancestor (UCA) at the root of the Tree of Life (ToL). That root polarizes the tree so that the evolutionary succession of ancestors to descendants is discernable. In effect, the root determines the branching order and the direction of character evolu

Calcium : A Crucial Potentiator for Efficient Enzyme Digestion of the Human Pancreas

Background: Effective digestive enzymes are crucial for successful islet isolation. Supplemental proteases are essential because they synergize with collagenase for effective pancreatic digestion. The activity of these enzymes is critically dependent on the presence of Ca2+ ions at a concentration of 5–10 mM. The present study aimed to determine the Ca2+ concentration during human islet isolation

Biogas Production from Food Residues—The Role of Trace Metals and Co-Digestion with Primary Sludge

The majority of municipal Wastewater Treatment Plants (WWTPs) in Sweden produce biogas from sewage sludge. In order to increase the methane production, co-digestion of internal sludge with Organic Fraction of Municipal Solid Waste (OFMSW) might be feasible in the future. The objective of this study was therefore to find a beneficial solution for the utilization of OFMSW at the WWTP in Varberg, Swe

Structured Laser Illumination Planar Imaging: New horizons for the study of spray dynamics, thermometry and droplet sizing

Thefirst reported applications of laser sheet imaging for the study of atomizing sprays date from the mid 1980th.Since those early tries, blurring effects from the light being scattered multiple times by the surrounding dropletswere already observed and reported. While s trategies in suppressing part of this multiple light scatteringcontribution, were known for transmission imaging (e. spatial Fou

Key components of successful transition for adolescents born with anorectal malformations-a Nordic focus group study

Transitional care for adolescents with congenital malformations, such as anorectal malformations (ARM), is described sparsely in the literature and referred to as being inadequate. In order to organize future successful healthcare structures, knowledge of patient-reported important aspects of transition is required. The aim of the study was therefore to explore the needs and expectations of transi

Global Response Patterns of Major Rainfed Crops to Adaptation by Maintaining Current Growing Periods and Irrigation

Increasing temperature trends are expected to impact yields of major field crops by affecting various plant processes, such as phenology, growth, and evapotranspiration. However, future projections typically do not consider the effects of agronomic adaptation in farming practices. We use an ensemble of seven Global Gridded Crop Models to quantify the impacts and adaptation potential of field crops

Making Blue Carbon : Coastal Ecosystems at the Science-Policy Interface

Klimatkrisen framstår mer och mer som det största hot människan någonsin ställts inför. Även om det politiska svaret kan beskrivas som avvaktande, pågår arbete för att på olika sätt minska klimatförändringarnas effekter, och hantera de risker vi kommer att ställas inför. Världssamfundet är enigt. Den globala medeltemperaturen bör inte öka med mer än 2 grader, och helst inte mer än 1,5 grader, jämfClimate change is a growing threat to mankind. The message from the scientific community is clear: we need to act fast and profoundly. The political response has, however, been slow. The likelihood that we will be able to meet our political climate goals only by reducing emissions is slim. Meanwhile is the interest around ways to capture carbon dioxide that has already been emitted on the rise. In

Benchmarking immunoinformatic tools for the analysis of antibody repertoire sequences

SUMMARY: Antibody repertoires reveal insights into the biology of the adaptive immune system and empower diagnostics and therapeutics. There are currently multiple tools available for the annotation of antibody sequences. All downstream analyses such as choosing lead drug candidates depend on the correct annotation of these sequences; however, a thorough comparison of the performance of these tool

Shifting Gears : Automated Driving on the Eve of Autonomous Drive

The compelling images and promises attached to autonomous drive vehicles can easily create an impression that one can speak of a radical distinction between a self-driving future and a manual-driving present. Yet today’s drivers can already refer to their everyday driving as being experienced as though on ‘auto-pilot’, in which they are able to drive their cars while lost in things such as daydrea

The irresistible solution: rationale and risks of extending water limits through desalination in the case of Gotland, Sweden

Water resources are under increasing pressure, and there are tensions between increasing demand and the natural limits to potable water supply. Authorities must find solutions that fulfil societal demands without compromising environmental integrity. As one way to counteract water deficits, desalination has evolved as an attractive solution. This technology is contested and associated with a varie

Unpacking challenges of data commentary writing in master’s thesis projects: an insider perspective from chemical engineering

Background: Data commentary, in-text comments on the visual presentation of data, is acknowledged as a central aspect of academic writing in many engineering disciplines. At the same time, it is a feature that it has been shown to be challenging for students. One of the genres in which data commentary plays a significant role in many engineering disciplines is the master’s thesis. Comparatively li

The role of mixotrophic protists in the biological carbon pump

The traditional view of the planktonic food web describes consumption of inorganic nutrients by photoautotrophic phytoplankton, which in turn supports zooplankton and ultimately higher trophic levels. Pathways centred on bacteria provide mechanisms for nutrient recycling. This structure lies at the foundation of most models used to explore biogeochemical cycling, functioning of the biological pump

Collectivity in the light radon nuclei measured directly via Coulomb excitation

Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state. A classic region for investigating this phenomenon is in the region around Z = 82 and the neutron midshell at N = 104. Purpose: Evidence for shape coexistence has been inferred from a-decay measurements, laser spectrosc

Impact of sample crushing on porosity characterization of hardened cement pastes by low temperature calorimetry : Comparison of powder and cylinder samples

The impact of sample crushing on the detected porosity of hardened cement pastes by low temperature calorimetry (LTC) was studied using powder and cylinder samples. Two types of cements, CEM I and CEM III were used to prepare the pastes. A model porous material, MCM-41, was also used in order to investigate some aspects of the measurement and the evaluation approach. The powder and cylinder sample

Polyporales brown rot species Fomitopsis pinicola : Enzyme activity profiles, oxalic acid production, and Fe3+-reducing metabolite secretion

Basidiomycota fungi in the order Polyporales are specified to decomposition of dead wood and woody debris and thereby are crucial players in the degradation of organic matter and cycling of carbon in the forest ecosystems. Polyporales wood-decaying species comprise both white rot and brown rot fungi, based on their mode of wood decay. While the white rot fungi are able to attack and decompose all

Low-Resolution Vision-at the Hub of Eye Evolution

Simple roles for photoreception are likely to have preceded more demanding ones such as vision. The driving force behind this evolution is the improvement and elaboration of animal behaviors using photoreceptor input. Because the basic role for all senses aimed at the external world is to guide behavior, we argue here that understanding this "behavioral drive" is essential for unraveling the evolu

Memory Image Completion : Establishing a task to behaviorally assess pattern completion in humans

For memory retrieval, pattern completion is a crucial process that restores memories from partial or degraded cues. Neurocognitive aging models suggest that the aged memory system is biased toward pattern completion, resulting in a behavioral preference for retrieval over encoding of memories. Here, we built on our previously developed behavioral recognition memory paradigm—the Memory Image Comple

Estimating soil salinity over a shallow saline water table in semiarid Tunisia

Rapid and reliable observations of soil electrical conductivity are essential in order to maintain sustainable irrigated agriculture. Direct measurement of the electrical conductivity of saturated soil paste (ECe), however, is tedious andtime consuming. Therefore, there are needs to find efficient indirect methods to predict the soil salinity from other readily available observations. In this pape

SufA of the opportunistic pathogen Finegoldia magna modulates actions of the antibacterial chemokine MIG/CXCL9, promoting bacterial survival during epithelial inflammation.

The anaerobic bacterium Finegoldia magna is part of the human commensal microbiota, but is also an important opportunistic pathogen. This bacterium expresses a subtilisin-like serine-proteinase, SufA, which partially degrade the antibacterial chemokine MIG/CXCL9. Here, we show that MIG/CXCL9 is produced by human keratinocytes in response to inflammatory stimuli. In contrast to the virulent human p
