Swallowing problems may be due to an abnormal transportation of food and drinks from the mouth to the stomach. The esophagram aims to monitor this and to reveal abnormalities in the morphodynamic process. It is important to analyze the patient’s symptom before the examination in order to custom-tailor the radiologic approach and to be able to explain the patients symptoms. Lower motor-neuron disea
Energy Management Systems (EMSs) often operate through inflexible, rule-based control systems. Model-free reinforcement learning (RL) has emerged as a promising alternative, providing adaptive and autonomous control without the need for detailed modeling. However, the complexity of operating energy systems and dynamic environmental conditions limits their practical use, with most studies relying o
Just as the cytomorphological picture is composed of several microscopic components, the cytodiagnostic conclusion should be supported by several other components, such as the clinical setting and the ancillary techniques applied, particularly flow cytometry and polymerase chain reaction (PCR)-based molecular genetic analyses for lymphomas, and immunohistochemistry for metastatic disease. In the s
Antiferromagnets are promising candidates for ultrafast spintronic applications, leveraging current-induced spin-orbit torques. However, experimentally distinguishing between different switching mechanisms of the staggered magnetization (Néel vector) driven by current pulses remains a challenge. In an exemplary study of the collinear antiferromagnetic compound Mn2Au, we demonstrate that slower the
An explicit algorithm is given for the computation of the Hausdorff dimension of the closure of a regular branch group in terms of an arbitrary branch structure. We implement this algorithm in GAP and apply it to a family of GGS-groups acting on the 4-adic tree.
The purpose of this narrative review is to provide an evidence-based update on management strategies for young adults with meniscal tears, based on two recent randomized controlled trials comparing a surgical vs. non-surgical treatment strategy for this patient group. The results from these trials suggests that exercise therapy is a viable treatment alternative for young adults with a meniscal tea
We study the impact of the early gender environment on inequality in the labor market. To this end, we link primary school data to occupations and earnings. We find that women exposed to more girls at critical ages earn more later on: A 10 percent increase in the share of girls leads to a gender wage gap reduction of 2.7 percent. We explore mechanisms and find a strong selection of women into less
Although communism was a Western creation, its last consequences were implemented in southeastern Europe. In addition to the imposed aspects, there were local enthusiasms and excesses of zeal (euphemistically speaking), which attest to the existence of an identity matrix and a common mentality. Countries with an authoritarian tradition have absorbed this ideology of simultaneous denationalization
We report on a single-shot longitudinal phase-space reconstruction diagnostic for electron beams in a laser wakefield accelerator via the experimental observation of distinct periodic modulations in the angularly resolved spectra. Such modulated angular spectra arise as a result of the direct interaction between the ultrarelativistic electron beam and the laser driver in the presence of the wakefi
Starting with the lead compound roquinimex, a selection of 3-quinolinecarboxamide derivatives were synthesized and evaluated for the treatment of the autoimmune disease multiple sclerosis. Structure-activity relationships were established in animal studies and from these, laquinimod was chosen as the drug candidate due to its superior potency and toxicological profile as compared to roquinimex. Ho
Den nationalekonomiska forskningen har genomgått en snabb utveckling under de senaste 10–20 åren. Nya teorier och nya forskningsfält har tillkommit. Traditionellt har man föreställt sig att ekonomisk teori bara är av värde för förståelsen av hur marknaden fungerar. Nu hävdar ekonomer att deras teori med fördel kan användas på alla sidor av det svenska samhället, även dem som vi betraktar som tillh
A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departure from the original approach pioneered by Sunada, where isospectral graphs are obtained as quotients of a certain large symmetric graph. Using the M-function formalism and the symmetries of the graph itself we construct
An emissions barrier was used in a premises due to complaints about the indoor air quality (IAQ) as a result of emissions from the building in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood and volatile organic compounds (VOCs), mainly 2-ethylhexanol, from polyvinyl chloride (PVC) flooring and the glue used to paste the f
In applied psychology, ontological assumptions are rarely subjected to scrutiny. Yet ontological positionings will affect all aspects of a research undertaking. Assumptions about what is real—and what is not—will affect conceptualization, study design, and analytical focus. In the investigation of social influence, failure to engage with ontological positionings has resulted in a default ontology
This study analyzes how violent conflict influences taxation in a poor, conflict-affected country, Burkina Faso. We use a unique, large, and representative panel dataset on tax collection of firms between 2015 and 2022 and geographically match these data with indicators of violent conflict at the municipal level. We find that firms pay a lower amount of tax in areas affected by violence. We also fThis study analyzes how violent conflict influences taxation in a poor, conflict-affected country, Burkina Faso.

Solar photo-voltaic (PV) and wind offer to bring both clean energy and clean water to remote regions and peri-urban areas in the world, outside the conventional electric grids. One out of seven people has no electric power available that would bring light to the home, cook the food, pump to access water and purify or re-use it. Off-grid systems are scalable and can be designed to any size, from ho
