Study of Dynamics in Metallic MEMS Cantilevers - Pull-In Voltage and Actuation Speed
For different metals and varying geometries, this paper presents simulations of electrostatically actuated MEMS cantilevers regarding their influence on pull-in voltage and actuation speed. Three-dimensional electromechanical modeling including many non-linearities has been performed to study some static but mainly dynamic features. The results show that the involved parameters have different influences on the actuation speed and pull-in voltage: lower length, higher thickness as well as lower density and higher ...
Postdoctoral employment and future nonacademic career prospects
Most recipients of doctorates leave universities some years after graduation, while little is known about their future non-academic career prospects. I report results from a novel microlevel database that links information about doctoral dissertations completed in Germany with doctorate recipients’ social security records. The results, based on graduates’ individual careers for five broader subject groups, indicate that postdoctoral periods do not result in a wage premium when changing to the non-academic sector.
Can group identity explain the gender gap in the recruitment process?
Despite evidence that the gender gap in the labour market favours men, aggregate findings from correspondence studies show that women are more likely than men to be invited for a job interview. We hypothesize that the predominance of women among recruiters may explain this somewhat puzzling finding; recruiters may favour applicants of their own gender. We use the data from a large-scale correspondence study to test this hypothesis. As expected, we find that female applicants are more likely to receive callbacks for ...
Mechanisms of one-photon two-site double ionization after resonant inner-valence excitation in Ne clusters
The role of interatomic and intermolecular energy and charge-transfer processes in weakly bound matter is currently lively debated due to emerging destructive low-energy electrons and radicals. Here, we discuss two mechanisms of single-photon two-site double ionization occurring competitively or subsequently to resonant interatomic Coulombic decay (rICD) in inner-valence (2s→np) excited Ne dimers and clusters. The first mechanism is photoelectron-impact ionization which is, in general, not related to resonant excitation, ...
On the implementation of large period piece-wise linear Arnold cat map
This paper presents a piece-wise linear cat map (PWLCM) obtained by perturbing the conventional quantized Arnold cat map (QACM) with a nonlinear term. The effect of the nonlinear term on the dynamics of the QACM is investigated. We show that the eigenvalues, hence the Lyapunov exponents of the PWLCM depend on the initial conditions, which is not the case for the QACM. As a result, the proposed PWLCM is a generalized form of the QACM, whose the period exponentially increases with respect to the precision, thus taking ...
Multi crop high efficiency seed drill with solar hybrid seed metering: A step toward precision and sustainability
High crop production with limited energy resources is always the priority area of developing countries. Conventional agricultural experimenting and crop production methods are time-consuming, challenging, laborious, and energy intensive. Various developments and experimental studies have been carried out for advancement in agriculture technologies. This study is mainly focused on the design and development of a unique high-efficiency seed drill machine to increase the energy efficiency of agricultural experiments, ...
Zur Rechtskonformität des Erfordernisses eines Lichtbildes für die eGK unter besonderer Berücksichtigung des Rechts auf informationelle Selbstbestimmung sowie der Vorgaben der DSGVO (Teil I)
Wiederholt war die elektronische Gesundheitskarte (eGK) Gegenstand von Gerichtsverfahren. Speziell die gesetzlich normierte Pflicht zur Beibringung eines aktuellen Lichtbildes zum Schutz vor Verwechslungen und Missbrauch und damit der unberechtigten Inanspruchnahme von Leistungen ist regelmäßig Anlass zur Klage. Bereits mehrmals entschied das BSG, dass die verpflichtende Aufnahme eines Lichtbilds eines Versicherten auf der eGK rechtmäßig sei. Ende 2021 (Az. L 4 KR 651/19) hat das LSG Bayern diese Rechtsauffassung ...
Conditions and Effects of Norm Internalization
Norm internalization refers to the process of adoption of normative beliefs by individuals, thus representing a link between individual and social change. However, there are several questions regarding norm internalization which need to be answered. These include understanding under which circumstances norm internalization does occur by considering the effects of internalizing either a certain norm or even conflicting norms. To investigate the conditions and effects of norm internalization, we developed a theoretical ...
Biogeography of the Sunda Shelf revisited: Insights from Macaranga section Pruinosae (Euphorbiaceae)
The Southeast Asian region of Sundaland is among the world’s major biodiversity hotspots. The region’s biodiversity coupled with its complex and dynamic geographic and climatic histories makes it an ideal region to study the various factors that determine the diversification and distribution patterns of tropical biota. Here we investigate the biogeographic patterns in the partly myrmecophytic Macaranga section Pruinosae to reveal some of the factors that play a role in determining the distribution of biota in Sundaland. ...
Genotyping by sequencing and a newly developed mRNA-GBS approach to link population genetic and transcriptome analyses reveal pattern differences between sites and treatments in red clover (Trifolium pratense L.)
The important worldwide forage crop red clover (Trifolium pratense L.) is widely cultivated as cattle feed and for soil improvement. Wild populations and landraces have great natural diversity that could be used to improve cultivated red clover. However, to date, there is still insufficient knowledge about the natural genetic and phenotypic diversity of the species. Here, we developed a low-cost complexity reduced mRNA analysis (mRNA-GBS) and compared the results with population genetic (GBS) and previously published ...
