Zusammenfassung
Ziel Von Peer- und Genesungsbegleiter*innen (=PGB*) wird erwartet, die
Kultur einer Versorgungseinrichtung zu verändern. Diese Arbeit untersucht, ob
und wie sich ein solcher Veränderungsauftrag umsetzen lässt.
Methoden Das Material speist sich aus zwei Teilen der ImpPeer-Psy5-Studie,
die bundesweit die PGB*-Implementierung in der krankenkassenfinanzierten
Versorgung untersucht. Daten aus 57 problemzentrierten Interviews und zwei
Fokusgruppen wurden mit der thematischen Analyse analysiert.
Ergebnisse PGB*benötigen Mut und Ausdauer, auch weil ihre
Veränderungsimpulse unzureichend aufgenommen werden. Das kann zur Wiederholung
von Ausschlusserfahrungen führen und dazu, dass PGB*sich an Handlungsweisen und
Haltungen der Teams anpassen.
Schlussfolgerungen Damit PGB*Veränderungsimpulse einbringen können, sollte
sich eine Einrichtung selbstständig auf einen Veränderungsweg begeben haben,
Machtverhältnisse und strukturelle Diskriminierung sollten reflektiert,
Austauschräume und eine Kritikkultur etabliert, und genug Zeit für die
Implementierung von PGB*eingeräumt werden.

Abstract
Objective Preeclampsia, whose pathophysiology is still not fully
elucidated today, is a pregnancy-specific disease that affects most organ
systems in pregnant women, including the central nervous system. In this
context, we aimed to investigate the effects of preeclampsia on blood flow in
the ophthalmic artery of the eye, which is considered a part of the central
nervous system.
Materials and Methods This prospective, non-interventional cohort study
was conducted between February 2022 and June 2022 at Umraniye Training and
Research Hospital, Department of Obstetrics and Gynecology, Istanbul, Turkey.
Forty-six normotensive healthy pregnant women constituted the control group and
46 preeclamptic pregnant women constituted the preeclampsia group. Prenatal
follow-up and delivery of the participants were carried out in our clinic.
First, an obstetric ultrasound was performed on all participants with the same
ultrasound device and the same clinician. Then, Doppler measurements of the
ophthalmic artery of both eyes were made by the same clinician using the linear
probe of the same ultrasound. Both groups were compared in terms of the first
peak of systolic velocity (PSV), second PSV, pulsatility index (PI), PSV ratio,
end-diastolic velocity (EDV), resistance index (RI), and systolic/diastolic
ratio (S/D) measurements of the ophthalmic artery.
Results The first PSV, second PSV, PSV ratio, and EDV were significantly
higher in the preeclampsia group than in the control group (p=0.001, p<0.001,
p=0.019, p<0.001, respectively). According to the receiver operating
characteristic analysis, the second PSV with a cut-off value of 43.75 cm/s was
the most powerful ophthalmic artery Doppler parameter in detecting preeclampsia
with 63% sensitivity and 63% specificity. No significant difference was found
between the early and late onset or mild and severe preeclampsia groups in terms
of ophthalmic artery Doppler parameters.
Conclusion Although the number of participants was too small to draw a
definitive conclusion, the second PSV seems to be the most powerful parameter
for the detection of preeclampsia. Studies with larger series are needed to
determine the usability of ophthalmic artery Doppler parameters in the routine
clinical diagnosis of preeclampsia and follow-up of the disease.

Published: August 2024

AbstractChronic and prolonged wounds are a serious public problem that may severely affect the quality of life and result in psychological pressure. Fibroblasts play a crucial role in the wound process and in skin pathology. Herbal drugs have long been used for wound care worldwide. Ajuga taiwanensis (Lamiaceae) is a folk medicine for antipyretics, anti-inflammation, and reducing swelling in Taiwan. This study aimed to investigate the effect of A. taiwanensis in wound healing and the underlying mechanisms. Under human dermal fibroblast (HDF) wound-healing activity-guided fractionation, we found that a sub-fraction (AT-M) of A. taiwanensis extract (AT) and the major ingredients significantly promoted wound healing and decreased IL-1β and − 6 expressions on HDFs. Furthermore, the fraction of AT-M enhanced wound healing on C57BL/6 mouse skins, increased PDGFR expressions, and activated the PDGFR/MAPK pathway. Taken together, A. taiwanensis extracts
promote wound healing by the PDGFR pathway and lead to enhanced cell spreading and motility, thereby having a possible beneficial effect on wound healing.

Published: August 2024

AbstractMushroom tyrosinase from Agaricus bisporus (abTYR) is often used during the development of tyrosinase inhibitors for medicinal and cosmetic purposes. In the search for novel tyrosinase inhibitors, this study identified hematoxylin as an alternative substrate for abTYR. The interaction of hematoxylin with abTYR was investigated through spectrophotometric and chromatographic analyses. The results showed that hematoxylin acted as an abTYR substrate and exhibited Michaelis–Menten kinetic behaviour at concentrations below 1.25 mM. The substrate properties of hematoxylin were similar to the natural tyrosinase substrate, L-3,4-dihydroxyphenylalanine (L-DOPA), with regards to Km, while Vmax was eightfold lower. The main oxidation product formed during the reaction of abTYR with hematoxylin was identified as hematein. This is the first report of the interaction of hematoxylin with abTYR.

AbstractThe measurement of fetal cardiovascular function parameters is not yet established in prenatal diagnostics. Now that the research field of fetal programming is becoming increasingly important, this might change. Fetal cardiovascular changes have been described above all in early/severe fetal growth restriction (FGR). The aim of this study was to investigate functional echocardiographic parameters in fetuses with late-onset small for gestational age (SGA)/FGR.A prospective cohort of SGA fetuses (including FGR) and a control group with similar distribution of gestational age were studied. Parameters of systolic, diastolic, and global cardiac function, morphometry and measurements of the fetal abdominal aorta were collected.A total of 149 SGA fetuses and 143 control fetuses were included from 32 weeks until term. The total SGA group was further divided into SGA 3rd–10th (fetuses between the 3rd and 10th weight percentile) and FGR subgroups. In the total SGA group, relative right and left ventricular wall thickness, left E/A ratio, isovolumetric contraction time and left myocardial performance index were significantly increased compared to controls after adjustment for gestational age. MAPSE, TAPSE, ejection time, left cardiac output, and abdominal aortic distensibility were significantly lower. The changes were more pronounced in the FGR subgroup.Even in a group of late-onset SGA/FGR, echocardiographic parameters are already altered in utero.
Urban design leadership: part 1, the styles of leadership
Authors: Carmona Matthew , Bento João 
Published: August 2024

AbstractThis paper, in two parts, explores the styles and application of urban design leadership as a dimension of urban design governance. Part 1 explores the literature on leadership and its relation to urban design. It discusses the relation of urban design leadership to places and situations, first connecting through the fundamentally integrative nature of the activity – vertically, horizontally, and temporally – and second influencing across professional, sectorial, and power contexts. It then conceptualises a typology of leadership – autocratic, paternalistic, democratic, laissez-faire, transactional, transformational, and absent – and considers how these leadership styles, none of which are absolute, influence the process and outcomes of urban design. The paper concludes with a framework for understanding urban design leadership that can be applied to the varied practices of urban design globally. Part 2 tests and illustrates this through its application to the roles and practices of Public Architects across Europe.
Unravelling the stylistic nuances: a comparative multidimensional analysis of amateur and professional translations of Legends of the Condor Heroes
Authors: Chou Isabelle , Xiang Zhangyujie , Liu Kanglong 
Published: August 2024

AbstractStyle research has always been an important field in corpus-based translation studies. However, the stylistic differences between amateur and professional translations of epic Chinese martial arts fiction have received limited attention in the existing literature. This study addresses this gap by examining the stylistic differences in amateur and professional translations of the novel Legends of the Condor Heroes, a representative work of this genre gaining popularity through fan-translation websites. Employing Biber’s multidimensional analysis, this study investigates fictional speech and narration in both amateur and professional translations. The findings reveal that amateur translations exhibit less variation between speech and narration, characterized by lower levels of involvement in dialog and reduced informational density in narrative passages. Moreover, amateur translations tend to employ more abstract language across both speech and narration compared to their professional counterparts. These stylistic disparities may influence readers’ comprehension and engagement with the text, potentially affecting their access to critical narrative elements. The study posits that the lack of professional training and experience, as well as the collaborative and open-source nature of amateur translation communities, may contribute to these observed differences in amateur translations. This research contributes to translation studies by examining stylistic differences between amateur and professional translations of Chinese martial arts fiction, potentially informing future studies on reader engagement and the reception of translated Chinese literature. The findings also highlight the importance of considering the impact of amateur translation practices on the dissemination and reception of popular genres in cross-cultural contexts.
3d orbital electron tunning and crystal engineering enables high-capacity vanadium oxide for aqueous ammonium ion batteries

Published: August 2024

Vanadium pentoxide (V2O5) has shown great potential as the electrode for aqueous ammonium ion batteries (AAIBs) owing to its good electrochemical reversibility and high theoretical capacity. However, the electrochemical performance of V2O5 is seriously limited by the weak NH4+ adsorption capability and insufficient active sites of vanadium oxide originated from the unsuitable 3d orbital electron state. Herein, the strategy of a 3d orbital electron tunning and crystal engineering is used to increase the ammonium ion storage capacity of V2O5 electrode. The experimental results show that the modified 3d orbital state of V4+ (t2g1) can effectively increase the active sites of V2O5. Therefore, the as-prepared N-VO exhibits a high specific capacity of 249.3 mA h g−1 at 1.0 A g−1 and 69.5 mA h g−1 at 10.0 A g−1, superior to other reported anode material for AAIBs. Noticeably, the prepared resultant quasi-solid-state ammonium ion battery can display considerable cycling stability with capacity retention of 87.9% after a long cycle life of 10 000 cycles at 1 A g−1 and impressive mechanical flexibility with no capacity decay after cycling at different bending angles.
Specific line shape of the lowest frequency Raman scattering modes of triethylene glycol
Authors: Ozama Koshi , Amo Yuko , Kameda Yasuo , Usuki Takeshi , Umebayashi Yasuhiro , Watanabe Hikari 
Published: August 2024

For both dielectric spectroscopy and light scattering spectra, the relaxation modes in the microwave region have been characterized by the Debye relaxation model, which is determined by the peak frequency, or by an empirically extended model (e.g., Cole–Davidson and Kohlrausch–Williams–Watts), which has the appropriate line shape. For light scattering from glass-forming liquids, the general line shape is a broader high frequency side in comparison with Debye relaxation. However, for triethylene glycol (TEG) in liquid form at room temperature, the lowest frequency Raman scattering (LFR) mode shows a peak at about 3.0 GHz, which is narrower than that expected for the Debye relaxation. With increasing temperature, this peak exhibits a significant blueshift and begins to resemble the Debye relaxation shape, indicating that the LFR mode of TEG is also a relaxation mode. The narrowing of the LFR mode of TEG is suggested to be caused from the increased non-whiteness of the fluctuation correlations due to increased hydrogen bonding. This is a consequence of breaking the Debye relaxation model’s approximation of the overdamping and narrowing limits in the GHz region, which was found in this study by analyzing the relaxation modes of Raman scattering using the multiple random telegraph model for evaluating thermal bath correlation. The analysis results show that the LFR relaxation times of TEG and the main dielectric relaxation overlap only by 333 K. However, the second LFR mode and β-relaxation at higher frequencies coincide over a wide temperature range, suggesting that they are corresponding modes.
Twistor theory of the Chen–Teo gravitational instanton*
Authors: Dunajski Maciej , Tod Paul 
Published: August 2024

Abstract
Toric Ricci–flat metrics in dimension four correspond to certain holomorphic vector bundles over a twistor space. We construct these bundles explicitly, by exhibiting and characterising their patching matrices, for the five–parameter family of Riemannian ALF metrics constructed by Chen and Teo. The Chen–Teo family contains a two–parameter family of asymptotically flat gravitational instantons. The patching matrices for these instantons take a simple rational form.
Effective anisotropic dynamics in group field theory cosmology
Authors: Oriti Daniele , Wang Yi-Li 
Published: August 2024

Abstract
We study the emergent dynamics of an anisotropic Universe in the context of group field theory condensate cosmology, with a scalar field playing the role of a relational clock. According to different definitions of ‘isotropy’, two anisotropic condensate states are considered and the Bianchi-like dynamics of cosmological anisotropic observables, as well as their quantum fluctuations, are analysed. We find that both anisotropic states become isotropic at late time, reproducing an effective Friedmann dynamics, while anisotropies give small but non-negligible contributions at earlier times, closer to the cosmic bounce.
On the implementation of acollinearity in PET Monte Carlo simulations

Published: August 2024

Abstract

Objective. Acollinearity of annihilation photons (APA) introduces spatial blur in positron emission tomography (PET) imaging. This phenomenon increases proportionally with the scanner diameter and it has been shown to follow a Gaussian distribution. This last statement can be interpreted in two ways: the magnitude of the acollinearity angle, or the angular deviation of annihilation photons from perfect collinearity. As the former constitutes the partial integral of the latter, a misinterpretation could have significant consequences on the resulting spatial blurring. Previous research investigating the impact of APA in PET imaging has assumed the Gaussian nature of its angular deviation, which is consistent with experimental results. However, a comprehensive analysis of several simulation software packages for PET data acquisition revealed that the magnitude of APA was implemented as a Gaussian distribution. Approach. We quantified the impact of this misinterpretation of APA by comparing simulations obtained with GATE, which is one of these simulation programs, to an in-house modification of GATE that models APA deviation as following a Gaussian distribution. Main results. We show that the APA misinterpretation not only alters the spatial blurring profile in image space, but also considerably underestimates the impact of APA on spatial resolution. For an ideal PET scanner with a diameter of 81 cm, the APA point source response simulated under the first interpretation has a cusp shape with 0.4 mm FWHM. This is significantly different from the expected Gaussian point source response of 2.1 mm FWHM reproduced under the second interpretation. Significance. Although this misinterpretation has been found in several PET simulation tools, it has had a limited impact on the simulated spatial resolution of current PET scanners due to its small magnitude relative to the other factors. However, the inaccuracy it introduces in estimating the overall spatial resolution of PET scanners will increase as the performance of newer devices improves.

Abstract
The development of textile-based strain sensors signifies a new era for diverse e-textile applications spanning various fields, including health monitoring and sensing equipment. Over decades, the sensor field has experienced significant advancements, incorporating enhancements in sensing accuracy, resolution, measurement range, and robustness, among other aspects. Our article initially focuses on the creation of textile-based strain membrane sensors customized for a range of industrial applications, such as air filter clogging detection and airflow analysis. In the subsequent part of the study, the reliability and washability performance of the sensing membrane, without mechanical damage, were investigated. To achieve this, thermoplastic polyurethane nanofibers were utilized to fabricate a textile sensory membrane. Subsequently, this membrane air transparent (low-pressure drop) and highly resilient was used as a substrate to print strain gauge tracks using carbon conductive ink, with the aid of a flexible printed circuit board printer. The resulting samples underwent comprehensive evaluation for reliability and washability. Prototype membranes were subjected to twelve wash cycles in a top-loading washing machine to assess washing reliability. Both the mechanical and electromechanical properties of the strain membrane sensors were examined both before and after the washing process. The gauge factor of the straight line decreased from 18.14 (region I) and 86.03 (region II) to 20.22 after washing. This value reduced from 0.88 and 4.20 to 0.33, and from 13 and 2.77 to 3.29 and 0.81 for the big zigzag and small zigzag, respectively. Similarly, electrical resistance change after 12 wash cycles was negligible with maximum change 1.12. These results indicate that sensors maintain their functionality even after exposure to multiple washing cycles. In conclusion, it can be inferred that textile-based sensory membranes are well-suited for industrial applications aiming at the measurement of low and high-speed airflows subject to rigorous washing and other potential mechanical stresses.

Published: August 2024

Abstract
Speckle noise limits the application of digital holography across various fields. This paper proposes a Non-local means filter method to suppress speckle noise by determining the weight of each traversed pixel based on the structural similarity between image blocks centered on the target and traversed pixels. Experimental results show that, compared to other typical digital image processing methods, this method can significantly reduce the speckle noise and exhibits a clear advantage across various metrics. These results indicate that the proposed method holds significant development potential in the field of speckle noise reduction.
Frozen condition of quantum coherence
Authors: Bai Zhaofang , Du Shuanping 
Published: August 2024

Abstract
Quantum coherence as an important physical resource plays the key role in implementing various quantum tasks, whereas quantum coherence is generally nonincreasing under incoherent operations. In this paper, we analyse under which dynamical conditions the l
1-norm or the relative entropy of coherence can remain unchanged under strictly incoherent operations (freezing coherence). We provide a detailed analysis of their structure together with exact geometric conditions of freezing coherence. It reveals a remarkable feature: any strictly incoherent operation freezing coherence can be decomposed as a convex combination of unitary operations. This partially answers an open question named unitary decomposition of doubly-stochastic quantum operations [M. A. Nielsen and I. L. Chuang, Quantum Computation and Quantum Information, (Cambridge University Press, Cambridge, 2000)]. Based on this analysis, we also give a complete classification of coherent states from operational coherence theory. This builds the counterpart of entanglement classification under LOCC.

Published: August 2024

Abstract
A terahertz hollow-core fiber having a double-layer ring core is presented and investigated to support OAM mode transmission. These two annular cores will work as two separate OAM transmission spaces that are not interfered with and can support more OAM mode transmissions. A numerical model has been developed to assess the transmission performances of EH and HE modes in the 0.3∼0.4 THz frequency band. Using only a single material to design the suggested fiber, 22 (in) + 58 (out) OAM modes can be stably transmitted at 0.36 THz. Neighboring EH and HE modes in the identical OAM family can obtain effective refractive index differences of more than 10−4. Furthermore, the designed fiber demonstrates excellent transmission properties, with the highest mode purities in the inner and outer rings being 92.22% and 93.78%, respectively. In the inner ring the effective mode field area is between 5.37 × 106 and 1.79 × 107 μm2, while in the outer ring, it is between 8.95 × 106 and 1.58 × 107 μm2. The HE1,1 mode has the smallest change in dispersion, with values of 2.76 and 0.87 ps THz−1 cm−1 in two high refractive index transmission ring cores, respectively. Additionally, the isolation (ISO) parameter is also analyzed. These mode characteristics indicate that the fiber structure has significant potential for applications in high-capacity terahertz communication systems.
