Design of a Mechatronic Interface with Compliant Manipulator for Robot Assisted Echocardiography
Abstract A compliant manipulator with a compound soft actuator is proposed for robot-assisted echocardiography. The target application is devoted to the TOE echo (Trans-oesophageal echocardiography), which is conventionally performed by medical practitioners. The manual manipulation of the echocardiography…

On Existence of Ground States in the Spin Boson Model
We show the existence of ground states in the massless spin boson model without any infrared regularization. Our proof is non-perturbative and relies on a compactness argument. It works for arbitrary values of the coupling constant under the hypothesis that the second derivative of the ground state energy…

Liquid Chromatography Analysis of Reactive Oxoammonium Cations
aus: Chromatographia
This study presents the first liquid chromatography method for the quantitative and qualitative analysis of highly reactive oxoammonium cations based on a simple derivatization reaction. Rapid 1,2-electrophilic addition reactions with olefins were used to transform these reactive species into analyzable…

Qualität in der Befundung von Kopf- und Halssonographien an Universitätskliniken – eine Stichprobe
Hintergrund: Die Ultraschalldiagnostik gilt für den Radiologen, Hals-Nasen-Ohren-Arzt (HNO) oder Mund-Kiefer-Gesichts-Chirurgen als Standard in der Abklärung zahlreicher Pathologien. Es besteht ein Konsens, dass die digitale Dokumentation heute dringend notwendig ist, um die Qualität der sonographischen…

Determinants of Electric Vehicle Diffusion in China
We analyze the effect of four determinants of electric vehicle diffusion in China for a panel of 31 regions for the period 2010–2016. We analyze diffusion of four different electric vehicle types, namely battery electric cars and buses as well as plug-in hybrid electric cars and buses. System GMM panel…

School Matters: The Effects of School Experiences on Youth’s Attitudes toward Immigrants
Although schools have been described as an important socialization context for the development of intergroup attitudes, longitudinal multilevel studies are still rare within this field. This 3-wave study (with annual assessments) of German adolescents ( N = 1292; M age = 13.86; 51.8% female) examined…

Topological concepts in partially ordered vector spaces
aus: Positivity
In the context of partially ordered vector spaces one encounters different sorts of order convergence and order topologies. This article investigates these notions and their relations. In particular, we study and relate the order topology presented by Floyd, Vulikh and Dobbertin, the order bound topology…

Order continuity from a topological perspective
aus: Positivity
We study three types of order convergence and related concepts of order continuous maps in partially ordered sets, partially ordered abelian groups, and partially ordered vector spaces, respectively. An order topology is introduced such that in the latter two settings under mild conditions order continuity…

Organic crystal-based THz source for complex refractive index measurements of window materials using single-shot THz spectroscopy
aus: Applied Physics A
Abstract We employed N-benzyl-2-methyl-4-nitroaniline (BNA) crystals bonded on substrates of different thermal conductivity to generate THz radiation by pumping with 800 nm laser pulses. Crystals bonded on sapphire substrate provided four times more THz yield than glass substrate. A pyrodetector and…

Effects of visual blur and contrast on spatial and temporal precision in manual interception
The visual system is said to be especially sensitive towards spatial but lesser so towards temporal information. To test this, in two experiments, we systematically reduced the acuity and contrast of a visual stimulus and examined the impact on spatial and temporal precision (and accuracy) in a manual…

Patient assessment and feasibility of treatment in older patients with cancer: : results from the IN-GHO ® Registry
Purpose: Predicting feasibility of treatment in older patients with cancer is a major clinical task. The Initiative Geriatrische Hämatologie und Onkologie (IN-GHO ® ) registry prospectively collected data on the comprehensive geriatric assessment (CGA), physician’s and patient’s-self assessment of fitness…

Making the COVID-19 crisis a real opportunity for environmental sustainability
An optimistic narrative has gained momentum during the first year of the pandemic: the COVID-19 crisis may have opened a window of opportunity to “rebuild better”, to spur societal transitions towards environmental sustainability. In this comment, we review first evidence of individual and political…

aus: Zeitschrift für Epileptologie : Organ der Deutschen Sektion der Internationalen Liga gegen Epilepsie
Hintergrund: Akut-symptomatische epileptische Anfälle treten in engem zeitlichem Zusammenhang mit einer akuten Störung der Hirnfunktion auf. Sie sind mit einem niedrigen Risiko späterer unprovozierter Anfallsrezidive assoziiert. Daher empfehlen aktuelle Leitlinien keine längerfristige medikamentöse Anfallsprophylaxe.…

Phytosterols and Cardiovascular Disease
Purpose of Review: Coronary heart disease is the leading cause of mortality worldwide. Elevated blood cholesterol levels are not only the major but also the best modifiable cardiovascular risk factor. Lifestyle modifications which include a healthy diet are the cornerstone of lipid-lowering therapy.…
