title: Assessment of femoral retroversion on preoperative hip magnetic resonance imaging in patients with slipped capital femoral epiphysis: Theoretical implications for hip impingement risk estimation
Creators: name: Kaim, Tilman Konstantin
Publisher: name: Universität Bern
Year: 2023
Subjects: subject: 610 Medicine & health

description: Purpose: Slipped capital femoral epiphysis is a common pediatric hip disease and was associated with femoral retroversion, but femoral version was rarely measured. Therefore, mean femoral version, mean femoral neck version, and prevalence of femoral retroversion were analyzed for slipped capital femoral epiphysis patients. 
Methods: A retrospective observational study evaluating preoperative hip magnetic resonance imaging of 27 patients (49 hips) was performed. Twenty-seven untreated slipped capital femoral epiphysis patients (28 slipped capital femoral epiphysis hips and 21 contralateral hips, age 10–16years) were evaluated (79% stable slipped capital femoral epiphysis, 22 patients; 43% severe slipped capital femoral epiphysis, 12 patients). Femoral version was measured using Murphy method on magnetic resonance imaging (January 2014–December 2021, rapid bilateral 3-dimensional T1 water-only Dixon-based images of pelvis and knee). All slipped capital femoral epiphysis patients underwent surgery after magnetic resonance imaging. 
Results: Mean femoral version of slipped capital femoral epiphysis patients (−1°±15°) was significantly (p<0.001) wider range from –42° to 35° (range 77°) compared to contralateral side (−5° to 44°, range 49°). Mean femoral neck version of slipped capital femoral epiphysis patients (6°±15°) was lower compared to contralateral side (11°±12°). Fifteen slipped capital femoral epiphysis patients (54%) had absolute femoral retroversion (femoral version<0°). Six of the 12 hips (50%) with severe slips and 4 of the 8 hips (50%) with mild slips had absolute femoral retroversion (femoral version<0°). Ten slipped capital femoral epiphysis patients (40%) had absolute femoral neck retroversion (femoral neck version<0°).
Conclusion: Although slipped capital femoral epiphysis patients showed asymmetrically lower femoral version compared to contralateral side, there was a wide range of femoral version, underlining the importance of patientspecific femoral version analysis on preoperative magnetic resonance imaging. Absolute femoral retroversion was prevalent in half of slipped capital femoral epiphysis patients, in half of severe slipped capital femoral epiphysis patients, and in half of mild slipped capital femoral epiphysis patients. This has implications for anterior hip impingement and for surgical treatment with in situ pinning or femoral osteotomy (e.g. proximal femoral derotation  osteotomy) or other hip preservation surgery.

description: Meßkampagnen mit Mikrobarometermeßnetzen haben in der Vergangenheit gezeigt daß sich in den Drucksignaturen nahezu permanent räumlich kohärente Strukturen (KST) abbilden. Ein Teil dieser KST wird durch Schwerewellen ausgelöst die in den verschiedensten Höhenbereichen der der Troposphäre angeregt werden und sich bis zum Boden ausbreiten. Ein anderer Teil zeigt keine für Wellen typischen Eigenschaften. So gibt es häufig zwar räumlich über mehrere Kilometer kohärente Strukturen doch sind diese zick-zack-förmig und sehen nicht wellenförmig aus. Ziel dieser Arbeit war es Indizien für die Ursachen dieser KST zu finden. Zur Untersuchung der KST wurde ein Mikrobarometermeßnetz am Observatorium des DWD in Lindenberg installiert. Mit ihm wurden zum einen über 12 Monate permanent Messungen durchgeführt die statistisch ausgewertet wurden.

description: Die vorliegende Studie befasst sich mit Phänomenen der Störung in Christian Krachts OEuvre und fragt danach, wie das Unbehagen der literarischen Öffentlichkeit mit diesem Autor zu erklären ist. Dabei werden journalistische und literarische Texte sowie die Selbstinszenierungsweisen des Autors auf die Verfahren hin untersucht, die die Irritationen hervorrufen.
Der Begriff „Störung“ wird in der Studie nicht negativ verstanden, sondern neutral als Irritation von Automatismen und Normalerwartungen definiert, denen durch den Regelverstoß das Potential innewohnt, die Reflexion von Normalitäts- und Akzeptabilitätsgrenzen anzustoßen. Die Studie nutzt Erkenntnisse kulturwissenschaftlicher Störungsforschung und einen darin verorteten diskursanalytischen Zugang, der Close Readings einzelner Texte in ihren Dispositiven verortet und hinsichtlich der zugehörigen Wertungsdiskurse beschreibt.
Die Untersuchung kommt zu dem Ergebnis, dass Kracht diverse Verfahren künstlerischer Transgression kombinierend einsetzt: Die Studie unterscheidet (narrations-)ästhetische, semiotische und hermeneutische Formen der Störung sowie Verfahren der Diskusstörung und medienreflexiver Störung im Handlungs- sowie Symbolsystem Literatur.
Die Untersuchung zeigt auf, dass diese Verfahren Krachts Poetik auch nach der Imperium-Debatte (2012) und den Kanonisierungstendenzen um den Autor in subtilerer Ausprägung kennzeichnen und diese in einem Spannungsverhältnis zu produktions- und rezeptionsseitigen werkpolitischen Entstörungstendenzen stehen.

description: The vetiver essential oil from Chrysopogon zizanioides contains fragrant sesquiterpenes used widely in the formulation of nearly 20% of men’s cosmetics. The growing demand and issues in the supply have raised interest in the microbial production of the sesquiterpene khusimol, the main compound of the vetiver essential oil due to its woody smell. In this study, we engineered the biosynthetic pathway for the production of (+)-zizaene, the immediate precursor of khusimol. A systematic approach of metabolic engineering in Escherichia coli was applied to modulate the critical bottlenecks of the metabolic flux towards (+)-zizaene. Initially, production of (+)-zizaene was possible with the endogenous methylerythritol phosphate pathway and the codon-optimized zizaene synthase (ZS). Raising the precursor E,E-farnesyl diphosphate supply through the mevalonate pathway improved the (+)-zizaene titers 2.7-fold, although a limitation of the ZS supply was observed. To increase the ZS supply, distinct promoters were tested for the expression of the ZS gene, which augmented 7.2-fold in the (+)-zizaene titers. Final metabolic enhancement for the ZS supply by using a multi-plasmid strain harboring multiple copies of the ZS gene improved the (+)-zizaene titers 1.3-fold. The optimization of the fermentation conditions increased the (+)-zizaene titers 2.2-fold, achieving the highest (+)-zizaene titer of 25.09 mg L−1. This study provides an alternative strategy to enhance the terpene synthase supply for the engineering of isoprenoids. Moreover, it demonstrates the development of a novel microbial platform for the sustainable production of fragrant molecules for the cosmetic industry.

description: The relativistic-like behavior of electrons in graphene significantly influences the interaction properties of these electrons in a quantizing magnetic field, resulting in more stable fractional quantum Hall effect states as compared to those in conventional (non-relativistic) semiconductor systems. In bilayer graphene the interaction strength can be controlled by a bias voltage and by the orientation of the magnetic field. The finite bias voltage between the graphene monolayers can in fact, enhance the interaction strength in a given Landau level. As a function of the bias voltage, a graphene bilayer system shows transitions from a state with weak electron-electron interactions to a state with strong interactions. Interestingly, the in-plane component of a tilted magnetic field can also alter the interaction strength in bilayer graphene. We also discuss the nature of the Pfaffian state in bilayer graphene and demonstrate that the stability of this state can be greatly enhanced by applying an in-plane magnetic field.

description: We investigate the implication of the nonlinear and non-local multi-particle Schrodinger-Newton equation for the motion of the mass centre of an extended multi-particle object, giving self-contained and comprehensible derivations. In particular, we discuss two opposite limiting cases. In the first case, the width of the centre-of-mass wave packet is assumed much larger than the actual extent of the object, in the second case it is assumed much smaller. Both cases result in nonlinear deviations from ordinary free Schrodinger evolution for the centre of mass. On a general conceptual level we include some discussion in order to clarify the physical basis and intention for studying the Schrodinger-Newton equation.

description: As the concept of ecosystem services is being operationalised and implemented in policies, a better guidance on the selection of suitable methods for ecosystem services mapping and assessment is needed to allow more sound, transparent and comparable processes. A vast range of assessments focusing on different sets of ecosystem services at various scales is existing and the applied methods cover different disciplines from ecology to economy and social sciences. This complicates the assessment of single or bundles of ecosystem services across spatio-temporal scales and requires a broad expertise. A tiered approach for ecosystem services assessment allows selecting the appropriate application of a certain method for tackling a specific question at a given scale. In this publication, we illustrate how the EU H2020 project ESMERALDA supported the development of such a tiered approach for assessing ecosystem services. The iterative exchanges between experienced researchers and practitioners in mapping and assessing ecosystem services in various contexts allowed the co-production of an approach to guide the choice of methods. Ultimately, the proposed tiered approach will not only support communication of the ecosystem services concept, but will also reduce the tendency for selecting an unsuitable approach for solving complex problems linked to ecosystem services-based resource management.

description: How can social science research aid advocacy efforts to address the intersection of race and poverty? How can researchers and activists in this area begin to network with each other on a regular basis to exchange information and develop strategies? A new organization, the Poverty & Race Research Action Council (PRRAC), has been convened by major civil rights, civil liberties and anti-poverty groups, to address these questions. With substantial initial support from the Rockefeller Foundation, funds will be channeled into research grants tied to local, state and national level advocacy strategies for litigation, legislation, community organizing, public education and other activities that support progressive social change. PRRAC will also establish a communications network among advocates and social science researchers. It will hold conferences,publish reports and disseminate ideas and materials.

description: The mobility of charge carriers across a semiconductor nanoparticle based 3D network (i.e. a gel) and the interfacial transfer of the charge carriers across the nanoparticle network/electrolyte boundary are elementary processes for applications in the fields of sensing and energy harvesting. The automated manufacturing of electrodes coated with porous networks can already be realized by inkjet printing. By simultaneous printing of CdSe/CdS dot-in-rod shaped nanorods (NRs) and the destabilization reagent, CdSe/CdS gel network coated electrodes can be obtained. In the presented work, the charge carrier mobility of the electrons and the holes within the porous CdSe/CdS nanorod gel network are investigated via photoelectrochemistry. Under application of linear sweep voltammograms (LSVs) and intensity modulated photocurrent spectra (IMPS) it is shown, that the electron is moving within the tip-to-tip connected CdSe/CdS NR gel structure, while the holes are trapped in the CdSe seed of the semiconductor heterostructures. Furthermore, the preparation process of gel structures is related to the elementary mechanism of hydration, which can be shown via photoelectrochemical long term studies.

description: The temperature dependence of elastic, dielectric, and piezoelectric properties of (65-x)Pb(Mg1/3Nb2/3)O3-xBaTiO335-PbTiO3 ceramics with x=0, 1, 2, 3, and 4 was investigated. Compound with x=2 was found to exhibit a large piezoelectric response (d31=-170 pC/N, d33=530 pC/N at 300 K). Particularly, its d31 value was nearly a constant over a temperature range from 185 to 360 K. A broad ferroelectric phase transition tuned by BaTiO3 doping was deduced from the dielectric constant, elastic compliance constant and Raman spectra. The temperature-stable piezoelectric response was attributed to the counter-balance of contributions from the dielectric and elastic responses.

description: We set up the general formalism to model polytropic Newtonian stars with anisotropic pressure. We obtain the corresponding Lane-Emden equation. A heuristic model based on an ansatz to obtain anisotropic matter solutions from known solutions for isotropic matter is adopted to illustrate the effects of the pressure anisotropy on the structure of the star. In particular, we calculate the Chandrasekhar mass for a white dwarf. It is clearly displayed how the Chandrasekhar mass limit changes depending on the anisotropy. Prospective astrophysical applications of the proposed approach are discussed.

Instead of assigning problems to isolated parts of government, the issues are increasingly being explored in an integrated manner, bringing together all concerned departments. Instead of maximizing current consumption with extractive, polluting industries and impersonal, inefficient governments, communities are striving to transform themselves to prosper in the long-run. It begins with the bringing together of all interests—business, government, environmental, labor, and public—to find new ways to operate which meet the needs of both the present and future generations.

description: We analyze Suzaku and XMM-Newton data of the highly variable Seyfert 2, IRAS 18325-5926. The spectra of the source are well modeled as a primary component described as an absorbed power law and a secondary power law component which is consistent with being scattered emission from an on-axis extended highly ionized medium. We show that while the primary component varies on a wide range of timescales from $10^{4} - 10^{8}$ s, the scattered emission is variable only on timescales longer than $10^{5}$ s. This implies that the extent of the scattering medium is greater than $10^{16}$ cm. The ratio of the scattered to primary flux ($\sim 0.03$) implies a column density for the scattering medium to be $\sim 10^{23}$ cm$^{-2}$. We argue that for such a medium to be highly ionized it must be located less than $10^{17}$ cm from the X-ray source. Thus we localize the position and extent of scattering region to be $\sim$ a few $\times 10^{16}$ cm, with an average particle density of $\sim 10^{6}$ cm$^{-3}$. We consider the physical interpretation of these results and as an aside, we confirm the presence of a broad Iron line emission in both the {\it XMM-Newton} and {\it Suzaku} observations.

description: Many rural areas at the suburban fringe are under pressure for development. Residents of these areas often advocate measures to preserve the rustic quality that make the areas so distinctive. The most common way is to establish agricultural zoning over the rural area or, alternatively, to zone it for a very low residential density, such as one home every twenty acres. A newer technique is to inaugurate a program to transfer development rights (TDR) from rural to urban locations.

description: Using a full implementation of resummed perturbation theory (PT) from a multi-point propagator expansion, we put forward new theoretical predictions for the two-point statistics of matter fluctuations in redshift space. The predictions consistently include PT corrections up to the two-loop order and are based on an improved prescription of the redshift-space distortions (RSD) that properly takes into account their non-Gaussian impact from a systematic low-k expansion. In contrast to the previous studies that partly used standard PT calculations, the present treatment is able to provide a consistent prediction for both power spectra and correlation functions. These results are compared with $N$-body simulations with which a very good agreement is found up to the quadrupole moment. The theoretical predictions for the hexadecapole moment of the power spectra are however found to significantly departs from the numerical results at low redshift. We examine this issue and found it to be likely related to an improper modeling of the RSD damping effects on which this moment shows large dependence.

description: The antisymmetry requirement of rishon bound state wave functions suggests a new rishon quantum number called M spin. From M spin conservation and the Nussinov-Weingarten-Witten theorem we predict the existence of a stable pseudoscalar dirishonic meson, called zeta, that is lighter than the lightest neutrino. Its mass is estimated as m(zeta) = 10^{-9} eV. This particle could make up the major part of cold dark matter in the Universe.

description: By combining rotation periods with spectroscopic determinations of projected rotation velocity, Jackson, Jeffries & Maxted (2009) have found that the mean radii for low-mass M-dwarfs in the young, open cluster NGC 2516 are larger than model predictions at a given absolute I magnitude or I - K color and also larger than measured radii of magnetically inactive M-dwarfs. The relative radius difference is correlated with magnitude, increasing from a few per cent at MI = 7 to greater than 50 per cent for the lowest luminosity stars in their sample at MI about 9.5. Jackson et al (2009) have suggested that a two-temperature star spot model is capable of explaining the observations, but their model requires spot coverage fractions of at least 50 per cent in rapidly rotating M-dwarfs. Here we examine these results in terms of stellar models that include the inhibiting effects of magnetic fields on convective energy transport, with and without the effects of star spots. We find that a pure spot model is inconsistent with the color - magnitude diagram. The observations of radii versus color and radii versus absolute magnitude in NGC 2516 are consistent with models which include only magnetic inhibition or a combination of magnetic inhibition and spots. At a given mass we find a large dispersion in the strength of the vertical component of the magnetic field in the stellar photosphere but the general trend is that the vertical field increases with decreasing mass from a few hundred Gauss at 0.65 Msun to 600 - 900 Gauss, depending on spot coverage, in the lowest mass stars in the sample at 0.25 Msun.

Scaling up the extrinsic curvature in gravitational initial data

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Vacuum solutions to the Einstein equations can be viewed as the interplay between the geometry and the gravitational wave energy content. The constraints on initial data reflect this interaction. We assume we are looking at cosmological solutions to the Einstein equations so we assume that the 3-space is compact, without boundary. In this article we investigate, using both analytic and numerical techniques, what happens when the extrinsic curvature is increased while the background geometry is held fixed. This is equivalent to trying to magnify the local gravitational wave kinetic energy on an unchanged background. We find that the physical intrinsic curvature does not blow up. Rather the local volume of space expands to accommodate this attempt to increase the kinetic energy.

First-principle interaction potentials for metastable He($^3$S) and Ne($^3$P) with closed-shell molecules. Application to Penning-Ionizing systems

description: We present new interaction potential curves, calculated from first-principle, for the He$(^3$S)$...$H$_2$ and He$(^3$S)$...$Ar systems, relevant in Penning's ionization experiments. Two different approaches were applied: supermolecular using coupled cluster theory (CC) and perturbational within symmetry-adapted perturbation theory (SAPT). Both methods gave consistent results and the potentials were used to determine the positions of shape resonances in low collision energy scattering regime. We found a good agreement with the most recent scattering experiment of Henson {\em et al.} [Science {\bf 338}, 234 (2012)]. In addition, we investigated two other dimers, composed of metastable Ne and ground state He and Ar atoms. For the Ne$(^3$P)$...$He system a good agreement between CC and SAPT approaches was obtained. The Ne$(^3$P)$...$Ar dimer was described only with SAPT, as CC gave divergent results. Ne$^*$ systems exhibit extremely small electronic orbital angular momentum anisotropy of the potentials. We attribute this effect to the screening of the open 2$p$ shell by the singly occupied 3$s$ shell.

description: We present a search for new physics using events with two same-sign isolated leptons with/out the presence of b-jets in the final state, targetting two very different SUSY scenarios, one dominated by strong production of squarks and gluinos where the 3rd generation squarks are lighter than other squarks and the other dominated by electroweak production neglecting completely any strongly interacting particles. No excees above the standard model background is observed. The results are interpreted in various SUSY models.

PIV study of the flow across the meridional plane of rotating cylinders with wide gap

description: This study investigates by Particle Image Velocimetry (PIV) the wavy Taylor vortex flow that develops in the gap between concentric rotating cylinders of low aspect ratio and low radius ratio, which is a configuration relevant to oil bearing chambers in turbomachinery. The configuration is characterised by a larger annular gap width than in classical journal bearing and by a Taylor number (Ta) of 2.47 × 106, which is 1000 times higher than the first critical Taylor number. It is found that the non-uniform axial spacing of the vortex cores induces an asymmetric radial velocity profile and an inflected axial velocity profile close to the cylindrical walls. The outflow at the centre of each pair of Taylor vortices that make up a vortex cell is strong and it is characterised by a sharp radial velocity peak. The inflow between pairs of Taylor vortex cells is unconventional in that it is characterised by pairs of confluent streams from the outer cylinder that merge towards the inner cylinder. These results form a body of experimental evidence on the flow features that may occur in engineering practice in oil bearing chamber flows, with relevance to lubrication and wear.
AGN III - primordial activity in nuclei of late-type galaxies with pseudobulges

description: 1. Based on observational data on evolution of quasars and galaxies of different types along with the results of numerical simulations we make a conclusion that on low redshifts ($z<0.5$) QSOI/II objects in massive elliptical and spiral galaxies with classical bulges cannot be in late single activity event (be "primordial"). Instead of it they have had events of activity earlier in their evolution. It means that their presence on low redshifts is connected with the recurrence phenomenon, sequential wet minor mergings, because timescale of the activity does not exceed several units of $10^7$ years. 2. We define a new class - "AGN III" as active galactic nuclei in isolated late-type spirals with low-mass rapidly rotating pseudobulges. We also state that only such objects can be in the primordial phase of activity at low redshifts. Black holes in such galaxies have masses $M_{BH}<10^7M_\odot$ and also, probably very high spin. Such properties can explain their peculiar emission spectra. A good representative of AGN III might be the galaxies with narrow (${\rm FWHM}(Hβ)\leq1200$ km/s) broad permitted emission lines - NLS. It is believed that their black hole masses are less than $M_{BH}<10^7M_\odot$ and their host galaxies have pseudobulges instead of the classical ones. Because host galaxies of NLS have pseudobulges and BLS (Broad-Line Seyfert galaxies) have classical bulges these two types of objects cannot have evolutionary connection. Presumably, the parent population of NLS are the quasars of "population A".
