Published: February 2023

ZusammenfassungBewegungsinterventionen sind in Gesundheitsförderung und
Prävention sowie Therapie und Rehabilitation essenziell, da Bewegung
positiv und multidimensional auf die Gesundheit wirkt. Zur Bewertung der
Wirkungsweise von Bewegungsinterventionen werden bisher oft Messmethoden
herangezogen, welche lediglich einen oberflächlichen Anteil der
erzielbaren Effekte abbilden. Eine Voraussetzung für eine erfolgreiche
Bewegungsintervention sind eine gute Adhärenz sowie ein
adäquates Dosis-Wirkungs-Prinzip. Wie die objektiven und subjektiven
Messgrößen in Zusammenhang mit der Adhärenz und
infolgedessen mit dem Dosis-Wirkungs-Prinzip stehen, ist nicht ausreichend
untersucht. In einer retrospektiven Datenanalyse von 66,988 chronischen
Rückenschmerzpatienten, die zwischen 1992 und 2021 an der FPZ
RückenTherapie teilgenommen haben, wurden die Zusammenhänge im
Ursachen- und Wirkungsdreieck zwischen Therapieadhärenz beziehungsweise
Dosis der verabreichten Trainingsreize und damit der benötigten Dauer
für ein Programm mit festgelegter Einheit an Trainingseinheiten, dem
Zugewinn an isometrischer Maximalkraft der Rumpfmuskulatur sowie dem Gewinn an
gesunden Lebensjahren untersucht. Es zeigt sich, dass der Kraftzuwachs
abhängig von der Zeit ist, die für die Therapie benötigt
wird. Eine andere zeitliche Abhängigkeit zeigt der Gewinn an gesunden
Lebensjahren mit steigendem Zeitrahmen, in dem die 24 Einheiten wahrgenommen
wurden. Kein Zusammenhang lässt sich dagegen zwischen dem relativen
Gewinn an isometrischer Maximalkraft und dem Gewinn an gesunden Lebensjahren
feststellen. Die Ergebnisse dieser Studie zeigen wichtige Zusammenhänge
zwischen dem zeitlichen Ablauf einer Therapie sowie den angewandten
Messparametern auf und sind damit wegweisend für zukünftige
Therapieformen. Bisherige Messmethoden müssen ergänzt werden, um
die Wirkungsweise von Bewegung und deren multidimensionale Effekte in
Gänze abbilden zu können.

ZusammenfassungDie beliebte Spielsportart Fußball ist durch ein hohes Spieltempo und
variable Belastungen charakterisiert. Sowohl im Leistungs- als auch im
Breitensport führt dies häufig zu Verletzungen insbesondere der
Muskulatur. Die am häufigsten betroffene Muskelgruppe ist die
ischiocrurale Muskulatur. Nach einer Verletzung wird eine schnelle
Rückkehr bei maximaler Leistungsfähigkeit in den Sport
angestrebt. Doch ein zu früher Einstieg in das Mannschaftstraining und
eine inadäquate Rehabilitation sind die häufigsten Ursachen
für eine Wiederverletzung. Deswegen besteht die Notwendigkeit eines
zeitlich und inhaltlich auf Verletzungen der ischiocruralen Muskulatur
optimierten Rehabilitationstrainings mit konkreten Trainingsinhalten und
Assessment-Tools zur Überprüfung der aktuellen Leistung, um die
Wiederverletzungsquote zu reduzieren.Der Return to Competition Algorithmus nach Bloch et al. (2019), der den Return to
Competition Prozess nach Verletzungen zeitlich optimiert, wurde durch die
Zuordnung spezifischer Trainingsinhalte und Assessment-Tools zu den einzelnen
Phasen des Rehabilitationsprozesses nach Verletzungen der ischiocruralen
Muskulatur spezifiziert. Der weiterentwickelte Algorithmus ist auf Verletzungen
der ischiocruralen Muskulatur abgestimmt und zeigt klare Kriterien zur Steuerung
des Rehabilitationsprozesses bis zum finalen Wiedereinstieg in den Sport
auf.

Abstract
Objectives Sellar pathologies are frequently found on imaging performed to investigate headache. However, both headache and incidental sellar lesions are common. Hence, this study prospectively examined headache prevalence, phenotype, and severity in patients with sellar pathologies and the impact of transsphenoidal surgery on headache.
Methods Patients undergoing transsphenoidal resection of sellar lesions were consecutively recruited. At baseline, participants were defined as having headache or not and headache phenotype was characterized using validated questionnaires. Headache severity was assessed at baseline and 6 months postoperatively using the Headache Impact Test-6 (HIT-6) and Migraine Disability Assessment Score (MIDAS). Tumor characteristics were defined using radiological, histological, and endocrine factors. Primary outcomes included baseline headache prevalence and severity and headache severity change at 6 months postoperatively. Correlation between headache and radiological, histological, and endocrine characteristics was also of interest.
Results Sixty participants (62% female, 47.1 ± 18.6 years) were recruited. Sixty-three percent possessed baseline headache. HIT-6 scores were higher in patients with primary headache risk factors, including younger age (R2  = −0.417, p = 0.010), smoking history (63.31 ± 7.93 vs 54.44 ± 9.21, p = 0.0060), and family headache history (68.13 ± 7.01 vs 54.94 ± 9.11, p = 0.0030). Headaches were more common in patients with dural invasion (55.70 ± 12.14 vs 47.18 ± 10.15, p = 0.027) and sphenoid sinus invasion (58.87 ± 8.97 vs 51.29 ± 10.97, p = 0.007). Postoperative severity scores improved more with higher baseline headache severity (HIT-6: R2 = −0.682, p < 0.001, MIDAS: R2 = −0.880, p < 0.0010) and dural invasion (MIDAS: −53.00 ± 18.68 vs 12.00 ± 17.54, p = 0.0030).
Conclusion Headaches in sellar disease are likely primary disorders triggered or exacerbated by sellar pathology. These may respond to surgery, particularly in patients with severe headache and dural invasion.
Anti-Markovnikov Hydrogermylation of Alkenes via Lewis Acid Catalysis
Authors: Schoenebeck Franziska , Selmani Aymane 
Published: February 2023

AbstractThe direct hydrogermylation of alkenes under Lewis acid catalysis is reported. The use of borane B(C6F5)3 as a catalyst allows for a mild, metal-free hydrogermylation of alkenes and concomitant reduction of ketones and aldehydes. Regardless of electronic biases, anti-Markovnikov hydrogermylation is observed in high yields. Moreover, the process is scalable and proceeds under mild conditions at room temperature.

Published: February 2023

AbstractWe report a nickel-catalyzed carbonylative cross-coupling of alkyl zinc reagents with α,α-difluorobromoacetamides to obtain α,α,-difluoro-β-ketoamides in moderate to good yields. The reaction is catalyzed by a bench-stable nickel(II) pincer complex, in contrast to other reports involving palladium catalysts. The carbonylative reaction is performed in a two-chamber system (COware) in which carbon monoxide (CO) is generated ex situ from the solid precursor SilaCOgen, and then consumed in the adjacent chamber. The reaction operates at low temperatures using near-stoichiometric amounts of CO. Isotopically labeled products can be effortlessly accessed, as demonstrated by using 13C-labeled SilaCOgen.

Published: February 2023

AbstractThis article demonstrates the ability to use autologous crushed cartilage grafts in rhinoplasty with rapid recovery and optimal nasal functionality without any tissue damage and allows its rapid rejuvenation. Eligible patients underwent primary rhinoplasty using autologous crushed cartilage graft followed by microscopy imaging of the grafted tissue after recovery. Tissue and cytological analysis using optical microscopy, transmission electronic microscopy (TEM), and scanning electronic microscopy (SEM) showed complete viability of chondrocytes, formation of new collagen fibers, neo-perichondrium, neo-angiogenesis, and exhibiting optimal aesthetic outcome. The surgical approach is easy to perform, feasible, and less time-consuming, with excellent tissue rejuvenation and rapid recovery.

Main text
The APMP/TCRI Dosimetry Working Group initiated the APMP.RI(I)-K3.2013 key comparison of measurement of air kerma for medium-energy x-rays (100 kV to 250 kV); measurements took place between 2015 and 2017. In total, 11 institutes took part in the comparison, among which 8 were APMP member laboratories, two from AFRIMETS and one from SIM. Three commercial cavity ionization chambers were used as transfer standards circulated among the participants. All the participants established 100, 135, 180 and 250 kV x-ray beam qualities equivalent to those of the BIPM. The ARPANSA and the NMIJ were linking laboratories and two participants subsequently made comparisons with the BIPM. The 7 other participants' degrees of equivalence fell within 11 parts in 103 of unity, well within the relevant expanded uncertainty (k = 2) in all cases. Excluding the BARC, the results were within 5.7 parts in 103, well within the relevant combined standard uncertainty. These results indicated that the calibration capabilities of most laboratories were in very good agreement and there were no serious discrepancies between them. The effect of implementing the recommendations of ICRU Report 90, which occurred on 1 January 2018 (after this comparison), is discussed and we deduce that the effect on the degrees of equivalence is negligible. The increase in the uncertainty in Wair has been added to all laboratories so that the degrees of equivalence and the uncertainties published here are applicable to post-ICRU 90 measurement results.

Uniqueness of relaxation times determined by dielectric spectroscopy
Authors: Wu Mengchun , Bichler Karin J , Jakobi Bruno , Schneider Gerald J 
Published: February 2023

Abstract
Dielectric spectroscopy is extremely powerful to study molecular dynamics, because of the very broad frequency range. Often multiple processes superimpose resulting in spectra that expand over several orders of magnitude, with some of the contributions partially hidden. For illustration, we selected two examples, (i) normal mode of high molar mass polymers partially hidden by conductivity and polarization and (ii) contour length fluctuations partially hidden by reptation using the well-studied polyisoprene melts as example. The intuitive approach to describe experimental spectra and to extract relaxation times is the addition of two or more model functions. Here, we use the empirical Havriliak-Negami function to illustrate the ambiguity of the extracted relaxation time, despite an excellent agreement of the fit with experimental data. We show that there are an infinite number of solutions for which a perfect description of experimental data can be achieved. However, a simple mathematical relationship indicates uniqueness of the pairs of the relaxation strength and relaxation time. Sacrificing the absolute value of the relaxation time enables to find the temperature dependence of the parameters with a high accuracy. For the specific cases studied here, the time temperature superposition (TTS) is very useful to confirm the principle. However, the derivation is not based on a specific temperature dependence, hence, independent from the TTS. We compare new and traditional approaches and find the same trend for the temperature dependence. The important advantage of the new technology is the knowledge of the accuracy of the relaxation times. Relaxation times determined from data for which the peak is clearly visible are the same within the experimental accuracy for traditional and new technology. However, for data where a dominant process hides the peak, substantial deviations can be observed. We conclude that the new approach is particularly helpful for cases in which relaxation times need to be determined without having access to the associated peak position.
Probabilistic seismic assessment of innovative concrete bridge piers with Engineered Cementitious Composites (ECC) by different types of shape memory alloys (SMAs) bars
Authors: Benshams Amirmozafar , Hatami Farzad , Saybani Mesbah 
Published: February 2023

Abstract
Critical role of bridges in post-earthquake rescue activities has made their seismic safety a major concern of structural engineers. While preventing collapse is one of essential requirements in bridge engineering, recent earthquakes have shown that bridges may also cease functionality due to residual deformations. To address this, shape memory alloys (SMAs) have received wide attentions according to their ability to recover the initial shape even after large plastic deformations. Two types of SMAs (NiTi and Cu–Al–Mn) are used in this paper to reinforce nine different concrete bridge piers in which Engineered Cementitious Composite (ECC) is also used for enhancing ductility in plastic hinge region. Each of the piers is subjected to 56 near field ground motions and collapse capacity of the piers is evaluated probabilistically using incremental dynamic analysis. The comparative results indicate that simultaneous use of steel and NiTi reinforcement in a plastic hinge area filled with ECC concrete can lead to a 30% improvement in median collapse capacity of the studied pier.
Enhanced generation and reception of ultrasonic Rayleigh waves through in-phase superposition of waves: theory and experiment
Authors: Zhang Shuzeng , Xie Lejuan , Wang Lei , Cheng Canhui 
Published: February 2023

Abstract
Ultrasonic Rayleigh waves have been widely used in nondestructive testing and evaluation as they are sensitive to surface anomalies and conditions of a solid body. The techniques for the generation and reception of Rayleigh waves are mainly based on empirical methods, but theoretical research on these processes can better benefit their practical applications. In this work, a specific theory using a numerical integration is proposed to model wave beam fields generated by the widely used transducers, and to explain the enhanced generation and reception of Rayleigh waves. The simulation results show that Rayleigh waves are enhanced and can be detected through in-phase superposition of waves which are generated by the real sound sources in the solid surface. The reception of Rayleigh waves is also considered, the properties of received waves are thoroughly studied and a reception method with a line source is proposed. Several experiments have been performed to verify the proposed theory, and some important properties or potential applications of corresponding or optimized transducers are discussed based on the theoretical and experimental results.

The goal is to explain why, in the large-q limit, the low-temperature dynamics freezes on some lattices while on others the equilibrium configuration is easily reached. The cubic (3d) and the triangular (2d) lattices are analysed in detail. We show that the dynamics blocks when lattices have acyclic unitary structures while the system goes to the equilibrium when these are cyclic, no matter the coordination number (z) of the particularly considered lattice.
Entanglement negativity in a fermionic chain with dissipative defects: exact results
Authors: Caceffo Fabio , Alba Vincenzo 
Published: February 2023

Abstract
We investigate the dynamics of the fermionic logarithmic negativity in a free-fermion chain with a localized loss, which acts as a dissipative impurity. The chain is initially prepared in a generic Fermi sea. In the standard hydrodynamic limit of large subsystems and long times, with their ratio fixed, the negativity between two subsystems is described by a simple formula, which depends only on the effective absorption coefficient of the impurity. The negativity grows linearly at short times, then saturating to a volume-law scaling. Physically, this reflects the continuous production with time of entangling pairs of excitations at the impurity site. Interestingly, the negativity is not the same as the Rényi mutual information with Rényi index

, in contrast with the case of unitary dynamics. This reflects the interplay between dissipative and unitary processes. The negativity content of the entangling pairs is obtained in terms of an effective two-state mixed density matrix for the subsystems. Criticality in the initial Fermi sea is reflected in the presence of logarithmic corrections. The prefactor of the logarithmic scaling depends on the loss rate, suggesting a nontrivial interplay between dissipation and criticality.

for the integer quantum Hall effect. It is merely a phenomenological formula in the sense that it is not based on any transport calculation for a specific class of physical models involving electrons in a disordered landscape, thus, whether a physical model exists which realizes this resistivity remains an open question. Nevertheless, since the formula involves the Riemann zeta function and its non-trivial zeros play a central role, it is amusing to consider the implications of the Riemann hypothesis in light of it.
The role of gene regulation in redundant and synergistic information transfers in coherent feed-forward loop
Authors: Aziz Momin Md Sorique , Biswas Ayan 
Published: February 2023

Abstract
For the ubiquitous coherent type-1 feed-forward loop (C1-FFL) motif, the master and co-regulators act as sources of information in decoding the output gene expression state. Using the variance-based definition of information within a Gaussian framework at steady state, we apply the partial information decomposition technique to quantify the redundant (common) and synergistic (complementary) information transfers to the output gene. By enabling the generic C1-FFL motif with complementarily tunable regulatory pathways and fixed gene product abundances, we examine the role of output gene regulation in maintaining the flow of these two multivariate information flavors. We find that the redundant and synergistic information transfers are simultaneously maximized when the direct and indirect output regulatory strengths are nearly balanced. All other manifestations of the generic C1-FFL motif, including the two terminal ones, namely, the two-step cascade and fan-out, transduce lesser amounts of these two types of information. This optimal decoding of the output gene expression state by a nearly balanced C1-FFL motif holds true in an extended repertoire of biologically relevant parametric situations. These realizations involve additional layers of regulation through changing gene product abundances, activation coefficients, and degradation rates. Our analyses underline the regulatory mechanisms through which the C1-FFL motif is able to optimally reduce its output uncertainty concurrently via redundant and synergistic modes of information transfer. We find that these information transfers are guided by fluctuations in the motif. The prevalence of redundancy over synergy in all regulatory implementations is also noteworthy.

Abstract
We have created a PCF with square shaped core using chalcogenide material As38Se62 as core and air holes in IR region, which yield very high optical non linearity of 1290 W−1Km−1 at 3.5 μm, further gives a flat dispersion profile. The fiber has been used for numerically simulate SCG using low power pump pulse width (TFWHM) at 50 fs duration at 3.5 μm. At the end of 10 mm fiber, SC broadening of about 2000 to 12000 nm can be achieved with pulses of 4200 W peak power.

Abstract
We designed a non-linear composite metamaterial made up of sandwiched fused silica glass with silver in an alternate manner with the magnitude of thickness is adjusted so that ε'=0 in the near infrared range., and the structure’s optical behaviour is theoretically studied. It shows a shift from negative to positive in the real component of dielectric permittivity as a function of wavelength. we also have studied the variation of ENZ wavelength with thickness of dielectric layer and plasma frequency. By using the Maxwell Garnett theory, we have calculated non-linear optical properties, and we find that as we increase the thickness of dielectric material the ENZ wavelength increases along with the increases in real part of non-linear susceptibility. A significant enhancement in nonlinear parameters has been also observed at ENZ wavelength due to the ENZ nature of the composite material.
