Long-Term Increase in Hibernating Bats in Swedish Mines - Effect of Global Warming?

We present the result of bat winter censuses in three old mines in southern Sweden from 1980 until present (2017). The Taberg and Kleva mines, each with about 1.5 km of accessible passages, have winter populations of 517 and 132 bats, respectively (maximum counts) belonging to six species, the highest numbers known in underground sites in Sweden. Ädelfors is less extensive and has fewer individual

Towards understanding learning challenges involving sign convention in introductory level kinematics

Coming to appropriately appreciate the meaning of algebraic signs is an important aspect in introductory kinematics. However, in this educational context, the “disciplinary relevant aspects“ of algebraic signs across vector and scalar representations are extremely difficult to discern. Our study explores the “relevance structure“ that one-dimensional kinematics problems evoked for introductory lev

Two-stage performance engineering of container-based virtualization

Cloud computing has become a compelling paradigm built on compute and storage virtualization technologies. The current virtualization solution in the Cloud widely relies on hypervisor-based technologies. Given the recent booming of the container ecosystem, the container-based virtualization starts receiving more attention for being a promising alternative. Although the container technologies are g

A new birthday-type algorithm for attacking the fresh re-keying countermeasure

The fresh re-keying scheme is a countermeasure designed to protect low-cost devices against side-channel attacks. In this paper, we present a new birthday-type attack based on a refined reduction to RING-LPN with a reducible polynomial. Compared with the previous research, our algorithm significantly reduces the time complexity in the 128-bit leakage model—with an SNR equal to 8.21 and at most 2

Plant-wide model-based analysis of iron dosage strategies for chemical phosphorus removal in wastewater treatment systems

Stringent phosphorus discharge standards (i.e. 0.15–0.3 g P.m −3 ) in the Baltic area will compel wastewater treatment practice to augment enhanced biological phosphorus removal (EBPR) with chemical precipitation using metal salts. This study examines control of iron chemical dosing for phosphorus removal under dynamic loading conditions to optimize operational aspects of a membrane biological r

Economic consequences of state failure; legal capacity, regulatory activity, and market integration in Poland, 1505-1772

With use of innovative proxies and new annual data, I demonstrate that relatively high legal capacity and regulatory activity of the early-modern Polish parliament, the Seym, was positively associated with deeper domestic commodity market integration. Conversely, the lack of effective law-making, caused by the right of a single delegate to discontinue the Seym's sessions, fostered market fragmenta

Impact of molecular linker size on physicochemical properties of assembled gold nanoparticle mono-/multi-layers and their applicability for functional binding of biomolecules

In this work the impact of molecular inter-linker size on gold nanoparticle (AuNP) mono-/multilayer structural properties, density and homogeneity has been investigated. These characteristics are of great importance for functional binding of biomolecules. Positively charged high or low molecular weight inter-linkers, poly-L-lysine (PLL) or N-(6-mercapto)hexylpyridinium (MHP), were used to attach n

Long term evolution of microstructure and stress around tin whiskers investigated using scanning Laue microdiffraction

Scanning Laue microdiffraction was used to study the evolution of the microstructure and the stress field around two tin whiskers during ageing for up to 21 months. In the heterogeneous stress fields obtained, localised ridges of high compressive stress leading to the root of the whiskers were found. Due to the evolution of the intermetallic compound in the interface between the copper substrate a

Tracking of geological structures and detection of hydrothermal intrusion by geo-electrical methods in the highlands of Bolivia

Oruro city in the Bolivian highlands depends solely on groundwater to supply domestic consumption and irrigation. The top porous aquifer currently exploited is not fully understood in aspects like geometry, hydrogeological properties and interaction with other aquifers in the region. Recent studies detected traces of fractures in the bedrock beneath the porous aquifer; these geological structures

Which advanced heart failure therapy strategy is optimal for patients over 60 years old?

BACKGROUND: The optimal advanced heart failure (HF) therapy strategy for patients aged 60 or older with end-stage HF refractory to optimal medical therapy remains uncertain. This study compares outcomes of three advanced HF therapy strategies in this patient population. METHODS: A single-center retrospective study was conducted in 95 patients aged 60-73 years who had undergone isolated heart trans

Antipsychotic Treatment Associated With Increased Mortality Risk in Patients With Dementia. A Registry-Based Observational Cohort Study

Objective: To assess all-cause mortality patients with dementia treated with typical and atypical antipsychotic drugs (APDs). Design: Registry-based cohort study. Setting and participants: A total of 58,412 patients diagnosed with dementia and registered in the Swedish Dementia Registry were included in the study. Of the study sample, 2526 of the patients were prescribed APDs. Of these, 602 patien

However, current methods that extend into the femtosecond regime arecapable of only point measurements or single-snapshot visualizations and thus lack the capability to perform ultrafast spectroscopicvideography of dynMany important scientific questions in physics, chemistry and biology require effective methodologies to spectroscopically probe ultrafast intra- and inter-atomic/molecular dynamics.

Exosomes in Parkinson's Disease : Current Perspectives and Future Challenges

Exosomes, which are lipid bilayer membrane vesicles, have been implicated as carriers of biological macromolecules. In recent years, the functions of exosomes in the spreading of pathological conversion of proteins among neurons have drawn particular attention in Parkinson's disease research. Extracellular α-synuclein is proven to be associated with exosomes in vivo and in vitro. The contents of t

Increased antibody levels to stage-specific Epstein–Barr virus antigens in systemic autoimmune diseases reveal a common pathology

The immune responses to antigens from different stages of the Epstein–Barr virus (EBV) life cycle were investigated in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjögren’s syndrome (SS), and systemic sclerosis (SSc) to gain knowledge of EBV’s involvement in the etiology of systemic autoimmune diseases (SADs) and for an overview of the humoral immune responses against EBV. Inves

Imagetext and ekphrasis as chances of revival in translation studies

Translation Studies has crossed a tumultuous interval of theorization. But has it passed the linguistic limits instituted by a semiotician like Umberto Eco? Wouldn’t be the time to access more courageously the intersemiotic interregnum with its heterogeneous transfer of signs? As it happens in advertising, concrete poetry, tattoos, and stage or filmed version of famous texts? If we have gradually

Man's Desire to be God

"Man's Desire to be God" is musical suite stretching from blues, rock, jazz to electronic music and classical music. Through particular performance methods in playing, singing, recording and producing the musical elements are blended together in a most mix. The concept and texts starts out from the sect around Charles Manson in the end of the 60s, out from where a story emerges that revolves aroun

CRITICAL INFRASTRUCTURES, GISCIENCE AND RISK GOVERNANCE: A LITERATURE REVIEW OF SYNERGISTIC RESEARCH OPPORTUNITIES

Critical infrastructures today are highly interdependent and increasingly important in providing services to the rest of the society. At the same time, each type of infrastructure requires specialised knowledge to design and manage. Therefore, to get a better understanding of how the infrastructures and the effect of interdependencies work as a whole, it is necessary to have an interdisciplinary a
