To ensure consistent performance of each test, it is necessary to adapt the power increase of the test protocol to the physical characteristics of each individual.

These new data reveal structure–property relationships affected by the presence and the position of the ether moiety in the molecular structure of the ether-alcohols. Compared to octan-1-ol, the presence of the ether moiety causes an increase in intermolecular hydrogen bonding interactions, resulting in higher densities. The increase in density is less pronounced for those ether-octanols that engage in intramolecular hydrogen bonding. As for the effects of the ether moiety on the dynamics, these are generally faster for the ether-alcohols compared to octan-1-ol, suggesting that hydrogen bonding between ether oxygen and hydroxy hydrogen is weaker compared to hydrogen bonding between two hydroxy groups. The activation energies obtained from an Arrhenius analysis are higher for translational motion than for momentum transfer for all alcohols. There are additional finer details across the ether alcohols for these activation barriers. These differences cancel out for the mathematical product of self-diffusion coefficient and viscosity (Dη). The effect of water impurities on the studied properties was also investigated and found to lead to small increases in densities for all alcohols.

To do this, use is made of high nitrogen steel as the rivet material. Successful joining with these rivets has already been proven, and it has also been shown that a competitive joint strength can be achieved with these rivets. Up until now, no studies have been conducted of the corrosion behaviour of uncoated rivets in high nitrogen steel compared to conventional rivets made of heat-treatable steel with a coating of Almac® or zinc-nickel with topcoat, and the corrosion behaviour of joints manufactured with these rivets has also not been investigated. Furthermore, the suitability of rivets in high nitrogen steel for structures undergoing cathodic dip painting has not been evaluated to date. These are therefore the aims of the research work presented in this paper. Corrosion behaviour is tested by exposing rivets and joints to a salt spray atmosphere. Cross-cut tests are conducted in order to classify the adhesion of cathodic dip paint to the different rivet surfaces and materials. The results of the experimental test show that the cathodic dip paint has sufficient adhesion to the uncoated rivets in high nitrogen steel and that these rivets can therefore be used in the manufacture of car bodies. Due to the stainless properties of the high nitrogen steel, better corrosion resistance is seen by comparison to the commonly used coatings of Almac® and zinc-nickel with topcoat. A study of the corrosion behaviour of the joints shows that the rivet head diameter and rivet head position, in particular, are decisive for preventing crevice corrosion under the rivet head and contact corrosion within the joint.

Traditionally, joints are cylindrical and rotationally symmetric. In the present study, non-rotationally symmetric joints are used for joining steel and Glass mat-reinforced thermoplastic sheets (GMT). In addition, the study also analyzes the impact of non-rotational symmetric joint rotation on the load-bearing capacity. Single lap joint specimens were fabricated using the In-Mold assembly technique for joining steel sheets with GMT. Tensile shear tests were performed on different orientations of the joint geometry, and it was observed that changing the joint orientation influences the load-bearing capacity. The joints are constitutively modeled using beam elements and the influence of joint rotation on load distribution is examined through a static simulation study. author: - first_name: Deekshith Reddy full_name: Devulapally, Deekshith Reddy id: '76837' last_name: Devulapally - first_name: Sven full_name: Martin, Sven id: '38177' last_name: Martin - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: 'Devulapally DR, Martin S, Tröster T.

This allows the generation of high-quality single photons without the need of complex laser stray light suppression or careful spectral filtering. In the present work, we extend this promising method to quantum emitters, specifically semiconductor quantum dots, inside a resonant optical cavity. A significant advantage of the SUPER scheme is identified in that it eliminates re-excitation of the quantum emitter by suppressing photon emission during the excitation cycle. This, in turn, leads to almost ideal single-photon purity, overcoming a major factor typically limiting the quality of photons generated with quantum emitters in high-quality cavities. We further find that for cavity-mediated biexciton emission of degenerate photon pairs, the SUPER scheme leads to near-perfect biexciton initialization with very high values of polarization entanglement of emitted photon pairs.\r\n \ \r\n \r\n \r\n \ \r\n Published by the American Physical Society\r\n 2024\r\n \ \r\n \r\n \ " article_number: L012017 author: - first_name: Nils full_name: Heinisch, Nils id: '90283' last_name: Heinisch orcid: 0009-0006-0984-2097 - first_name: Nikolas full_name: Köcher, Nikolas id: '79191' last_name: Köcher - first_name: David full_name: Bauch, David last_name: Bauch - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 citation: ama: 'Heinisch N, Köcher N, Bauch D, Schumacher S.

A grassroots movement of mosques tries to reduce prejudice by organizing guided mosque tours for non-Muslims. While this is an opportunity for intergroup contact in a social psychological sense, contact occurs under sometimes difficult conditions. As yet, its effects have not been investigated empirically. Objective We examine (a) whether visits have an immediate and medium-term effect on prejudice toward Islam and (b) how they change the visitors’ subjective images of Muslims. Methods (a) We survey N = 324 secondary school students in a three-wave panel study in 6 guided mosque tours in different parts of Germany, including a control sample. The tour programme was in line with common practice in the mosques. Standardized measurements were taken immediately before and after the tour and again several months later. (b) We asked about subjective images of Muslims and had subjects report their spontaneous associations with the term Muslim. Results (a) Most, but not all, mosque visits significantly alleviate anti-Islam prejudice in the short term. The effects fall off after several months. (b) After the visit, the image of Muslims possessed more concrete religious content, while negative and menacing associations, such as oppression of women, threat, or so-called Islamic State have decreased. Conclusions Outgroup contact in a mosque works as predicted by the intergroup contact research, even under less than optimal conditions. However, there is potential for improvement of the setup of tours in the interest of a more sustainable impact. author: - first_name: Olga full_name: Janzen, Olga last_name: Janzen - first_name: Isabell full_name: Diekmann, Isabell id: '119325' last_name: Diekmann - first_name: Dorian full_name: Tsolak, Dorian last_name: Tsolak - first_name: Kurt full_name: Salentin, Kurt last_name: Salentin citation: ama: Janzen O, Diekmann I, Tsolak D, Salentin K.

Ja, denn die längere Geschichte der Digitalisierung, in der die „sozialen Medien“ einzuordnen sind, zählt bereits über 80 Jahre. Konrad Zuse und andere Ingenieure entwickelten seit 1941 die ersten Digitalcomputer, Unternehmer*innen, Wissenschaftler*innen und Staatenlenker*innen setzten diese seit den 1950er Jahren für ihre Zwecke ein, die Zivilgesellschaft adaptierte sie in den darauffolgenden Dekaden – all das prägte die sozio-digitale Landschaft der späteren „sozialen Medien“. Als unmittelbar „nach dem Boom“ etwa um 1970 zahlreiche Industriegesellschaften einen strukturellen Wandel in Wirtschaft, Gesellschaft und Politik durchlebten, war eine Antwort darauf die vermehrte Digitalisierung und Vernetzung. Daraus entwickelte sich die 1990er Jahre als markante Dekade von World Wide Web, Google und Chatdiensten. Die Entwicklung der „sozialen Medien“ ist also unter anderem in eine ökonomische und gesellschaftliche Entwicklung der Aufmerksamkeitsökonomie und in die längeren Veränderungen von Wirtschafts- und Gesellschaftsordnungen der Ausdifferenzierung und partiellen Individualisierung seit den 1960er Jahren einzuordnen. Dadurch lässt sich besser verstehen, welche Prämissen ihnen zugrunde lagen, welche Möglichkeitsräume und Probleme sich daraus ergaben und warum sie die heutige Öffentlichkeit in einer bestimmten Art und Weise dominieren – ohne sie jedoch zu determinieren. author: - first_name: Martin full_name: Schmitt, Martin id: '100968' last_name: Schmitt citation: ama: 'Schmitt M.

Here, we realize the implementation of programmable unitary operations on up to 64 frequency-bin modes. To benchmark the performance of our system, we probe different quantum walk unitary operations, in particular, Grover walks on four-dimensional hypercubes with similarities exceeding 95% and quantum walks with 400 steps on circles and finite lines with similarities of 98%. Our results open a path toward implementing high-quality unitary operations, which can form the basis for applications in complex tasks, such as Gaussian boson sampling.\r\n \r\n \ \r\n \r\n \r\n \ Published by the American Physical Society\r\n \ 2024\r\n \r\n \ \r\n " article_number: L022040 author: - first_name: Syamsundar full_name: De, Syamsundar last_name: De - first_name: Vahid full_name: Ansari, Vahid last_name: Ansari - first_name: Jan full_name: Sperling, Jan id: '75127' last_name: Sperling orcid: 0000-0002-5844-3205 - first_name: Sonja full_name: Barkhofen, Sonja id: '48188' last_name: Barkhofen - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: De S, Ansari V, Sperling J, Barkhofen S, Brecht B, Silberhorn C.
