Evaluating objective measures of impairment to trunk strength and control for cross-country sit skiing

2021

AbstractIn Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected by subjectivity. An evidence-based classification is required, in which objective measures of impairment must be identified. The purposes of this study were: (i) to evaluate the reliability of 5 trunk strength measures and 18 trunk control measures developed for the purposes of classification; (ii) to rank the objective measures, according to the largest effects on performance. Using a new testing device, 14 elite sit-skiers performed two upright seated press tests and one simulated poling test to evaluate trunk strength. They were also subjected to unpredictable bal…

Shell Model Description of Spin-Dependent Elastic and Inelastic WIMP Scattering off 119Sn and 121Sb

2022

In this work, we calculate the spin structure functions for spin-dependent elastic and inelastic WIMP scattering off 119Sn and 121Sb. Estimates for detection rates are also given. 119Sn and 121Sb are amenable to nuclear structure calculations using the nuclear shell model (NSM). With the possible exception of 201Hg, they are the only such nuclei still unexplored theoretically for their potential of inelastic WIMP scattering to a very low excited state. The present calculations were conducted using a state-of-the-art WIMP–nucleus scattering formalism, and the available effective NSM two-body interactions describe the spectroscopic properties of these nuclei reasonably well.

Der Spur auf der Spur. Sur les traces de la trace

2016

Hinter dem scheinbar einfachen lexikalischen Gewand der »Spur« verbirgt sich eine überraschende Komplexität: Was ist eigentlich eine Spur? Was sind ihre typischen Merkmale? Wodurch unterscheidet sie sich von Abdruck, Zeichen und Indiz? Die Beiträge des vorliegenden Bandes reflektieren den Spurbegriff aus deutsch-französischer sowie aus interdisziplinärer Perspektive. Zu Wort kommen Philosophie, Literatur, Geschichte, Archäologie, Kunstgeschichte, Urbanistik, Kulturwissenschaft und Psychoanalyse.

Spin and charge currents driven by the Higgs mode in high-field superconductors

2020

The Higgs mode in superconducting materials describes slowly decaying oscillations of the order parameter amplitude. We demonstrate that in superconductors with a built-in spin-splitting field the Higgs mode is strongly coupled to the spin degrees of freedom, allowing for the generation of time-dependent spin currents. Converting such spin currents to electric signals by spin-filtering elements provides a tool for the second-harmonic generation and the electrical detection of the Higgs mode generated by the external irradiation. The nonadiabatic spin torques generated by these spin currents allow for the magnetic detection of the Higgs mode by measuring the precession of the magnetic moment…

The complementary structural studies of the double metal cyanide type catalysts for the ring opening polymerization of the oxiranes

2016

Przeprowadzono badania strukturalne katalizatorów dimetalocyjankowych (DMC) z dwoma rodzajami ligandów organicznych. Zaproponowano wyjaśnienie etapów przebiegu krzywych otrzymanych metodą analizy termograwimetrycznej i różnicowej kalorymetrii skaningowej (TG/DSC) badanych katalizatorów. Wykazano obecność kilku stopni związania ligandów w kompleksach DMC. Na podstawie wyników badań z wykorzystaniem absorpcji rentgenowskiej (XAS) stwierdzono, że centrum aktywne katalizatora stanowi atom cynku. W bezpośrednim sąsiedztwie atomów Zn wykryto obecność atomów Cl, natomiast w najbliższych sferach koordynacyjnych atomu Zn nie wykryto atomów tlenu.

Increasing intensity of deimatic behaviour in response to repeated simulated attacks: a case study on the mountain katydid (Acripeza reticulata)

2022

Abstract How and when deimatic behaviours are performed can change during encounters between predators and prey. Some predators attack repeatedly, investigating and manipulating prey, and in response, an individual’s deimatic behaviour may intensify or may diminish in favour of escaping. The presence of a resource can further force a trade-off between displaying and escaping. Here, we examined the intensity of the katydid’s deimatic behaviour, a visual display, the propensity of their escape response under repeated simulated attacks, and how these responses change in the presence of foraging resources. We found that display intensity increased with repeated simulated attacks and that femal…

Käsivedon muuttujien yhteys viidenkymmenen metrin vapaauinnin aikaan : uuden anturiteknologiaan perustuvan tehomittarin testaus

2017

Johdanto. Uimari on uidessaan käytännössä lähes koko vartalollaan kosketuksissa veteen. Vesi on väliaine, joka vastustaa uimarin etenemistä ja josta voiman ja vastavoiman periaatteen mukaisesti uimaria eteenpäin vievien voimien tukipinnat tulisi löytää. Veden viskoelastinen luonne luo omat erityispiirteensä eteenpäin suuntautuvien ja vastustavien voimien välille. Tässä tutkimuksessa keskitytään vapaauinnin käsivedon muuttujiin, joiden avulla pyritään arvioimaan uimarin käsivedon eteenpäin vieviä voimia ja niiden yhteyttä uintinopeuteen. Tämän lisäksi tutkitaan anturiteknologiaan perustuvan tehomittarin reliabiliteettia ja arvioidaan validiteettia. Menetelmät. Koehenkilöinä oli kansallisen j…

Reactions of m-Terphenyl-Stabilized Germylene and Stannylene with Water and Methanol: Oxidative Addition versus Arene Elimination and Different React…

2015

Reactions of the divalent germylene Ge(ArMe6)2 (ArMe6 = C6H3-2,6-{C6H2-2,4,6-(CH3)3}2) with water or methanol gave the Ge(IV) insertion product (ArMe6)2Ge(H)OH (1) or (ArMe6)2Ge(H)OMe (2), respectively. In contrast, its stannylene congener Sn(ArMe6)2 reacted with water or methanol to produce the Sn(II) species {ArMe6Sn(μ-OH)}2 (3) or {ArMe6Sn(μ-OMe)}2 (4), respectively, with elimination of ArMe6H. Compounds 1–4 were characterized by IR and NMR spectroscopy as well as by X-ray crystallography. Density functional theory calculations yielded mechanistic insight into the formation of (ArMe6)2Ge(H)OH and {ArMe6Sn(μ-OH)}2. The insertion of an m-terphenyl-stabilized germylene into the O–H bond was…
