Ultrasound in sports traumatology
Authors: Lerchbaumer Markus Herbert , Perschk Maximilian , Gwinner Clemens 
Published: November 2023

Background Ultrasound (US) has numerous applications in sports traumatology. The technical progress of mobile US devices has led to increasing use of ultrasound as a primary diagnostic tool. New applications such as elastography and 3 D vascularization are used for special indications.
Method The purpose of this review is to present the current status of ultrasound in the diagnosis of sports injuries and sport traumatology including established applications and new technical advances. US is presented both in its comparison to other imaging modalities and as a sole diagnostic tool.
Results and Conclusion US can be used for initial diagnosis to improve the clinical examination and for intensive short-term follow-up imaging. The main areas of application are currently the diagnosis of acute muscle and tendon injuries as well as overuse injuries. In particular, the exclusion of structural muscle injuries can be adequately ensured with US in the majority of anatomical regions. The recently published guideline on fracture ultrasound has strengthened the clinical evidence in this area, especially in comparison to conventional radiography and in the development of algorithms and standards. The increasing use of mobile ultrasound equipment with adequate image quality makes US a location-independent modality that can also be used at training sites or during road games.

Imaging findings and treatment in coccydynia – update of the recent study findings
Authors: Sukun Abdullah , Cankurtaran Tijen , Agildere Muhteşem , Weber Marc-André 
Published: November 2023

Background Coccydynia is one of the most overlooked symptoms in clinical practice. The diagnosis and radiologic findings of traumatic coccyx can be more easily detected unless it is delayed and postponed. For idiopathic coccydynia, which accounts for one third of cases, patients present with long-standing pain and multiple physician visits.
Method The keywords coccyx, coccydynia, coccygodynia were searched in PubMed, Embase, Scopus databases in the last 5 years. Research articles, reviews and case reports were analyzed. The studies conducted in the last 5 years were presented under the headings of etiology, radiologic assessment, interventional and surgical treatments.
Results and Conclusion The first step is dynamic X-ray of the coccyx in standing and sitting position. In this way, morphologic parameters and hypermobility causing idiopathic coccydynia can be evaluated. Morphologic and morphometric features of the coccyx described in previous CT and MR studies have explained the relationship with coccydynia. The key features are as follows: Type II coccyx morphology, subluxation of the intercoccygeal joint, presence of bony spicules. Knowledge of these definitions as well as the differential diagnosis in this anatomical region will help in reaching the correct diagnosis. The treatment of coccydynia is stepwise like the diagnosis. Conservative treatments are initiated first. Manipulations, ganglion impar block, injections, radiofrequency and shock treatments and finally coccygectomy are treatment methods reported. Radiologists should not overlook this region and should be familiar with the coccyx’s morphologic appearance and the sacrococcygeal region’s differential diagnosis.

Abstract
Background Device-assisted enteroscopy (DAE) has become a well-established diagnostic and therapeutic tool for the management of small-bowel pathology. We aimed to evaluate the performance measures for DAE across the UK against the quality benchmarks proposed by the European Society of Gastrointestinal Endoscopy (ESGE).
Methods We retrospectively collected data on patient demographics and DAE performance measures from electronic endoscopy records of consecutive patients who underwent DAE for diagnostic and therapeutic purposes across 12 enteroscopy centers in the UK between January 2017 and December 2022.
Results A total of 2005 DAE procedures were performed in 1663 patients (median age 60 years; 53% men). Almost all procedures (98.1%) were performed for appropriate indications. Double-balloon enteroscopy was used for most procedures (82.0%), followed by single-balloon enteroscopy (17.2%) and spiral enteroscopy (0.7%). The estimated depth of insertion was documented in 73.4% of procedures. The overall diagnostic yield was 70.0%. Therapeutic interventions were performed in 42.6% of procedures, with a success rate of 96.6%. Overall, 78.0% of detected lesions were marked with a tattoo. Patient comfort was significantly better with the use of deep sedation compared with conscious sedation (99.7% vs. 68.5%; P<0.001). Major adverse events occurred in only 0.6% of procedures.
Conclusions Performance measures for DAE in the UK meet the ESGE quality benchmarks, with high diagnostic and therapeutic yields, and a low incidence of major adverse events. However, there is room for improvement in optimizing sedation practices, standardizing the depth of insertion documentation, and adopting marking techniques to aid in the follow-up of detected lesions.

Published: November 2023

AbstractThe present study discloses an NIS/PPh3-mediated reductive self-coupling of arylsulfonyl hydrazides to prepare symmetric diaryl disulfides. This methodology has a broad functional-group tolerance and a high scalability. This strategy permits the introduction of sulfonyl hydrazides into the synthesis of symmetrical organic disulfides without the use of a catalyst or base, and symmetrical aromatic disulfides can be prepared in moderate to excellent isolated yields from inexpensive and readily available starting materials.

AbstractThis Account summarizes the highly appealing dearomatization reactions of β-naphthols for the synthesis of highly functionalized, three-dimensional structures starting with simple planar aromatic compounds. The reactions are categorized mainly from the viewpoint of the construction of carbon–hydrogen, carbon–carbon, and carbon–hetero bonds (C–N/O, C–Cl, C–F) at the α-position of β-naphthols. The dearomatized products play an important role in organic synthesis and materials science.1	Introduction2	Construction of Carbon–Hydrogen Bonds at the α-Position of β-Naphthols3	Construction of Carbon–Carbon Bonds at the α-Position of β-Naphthols4	Construction of Carbon–Nitrogen/Oxygen Double Bond at the α-Position of β-Naphthols5	Construction of Carbon–Carbon and Carbon–Oxygen Bonds at the α-Position of β-Naphthols6	Construction of Carbon–Halogen Bonds at the α-Position of β-Naphthols7	Conclusion
The Effect of Body Mass Index on Post-Bolus Magnesium Levels in the Obstetric Patient
Authors: De Zoysa Madushka Y. , Westermann Melissa , Yang Tyler , Chung Judith H. 
Published: November 2023

Objective In the setting of a growing obese obstetric population, we sought to determine whether differences in body mass index (BMI) and obesity class influenced both serum magnesium levels and the likelihood of achieving therapeutic levels for eclampsia prophylaxis after standard boluses of magnesium sulfate.
Study Design This is a retrospective cohort study of patients treated with magnesium sulfate in the setting of either preeclampsia with severe features or preterm labor between 2010 and 2016. Subjects were categorized by BMI: Normal (BMI < 30 kg/m2), Class 1 (BMI 30–34.9 kg/m2), Class 2 (BMI 35–39.9 kg/m2), and Class 3 (BMI ≥ 40 kg/m2). Study participants' demographics, intrapartum characteristics, and adverse reactions were compared among the groups. Logistic regression models were used to calculate unadjusted and adjusted odds ratios comparing the likelihood of each BMI class reaching therapeutic eclamptic prophylactic levels. Linear regression models were also evaluated to determine the relationship between BMI and post-bolus serum magnesium levels.
Results Of the 760 people who met the inclusion criteria, 313 (41.1%) had normal BMI, 190 (25.0%) had Class 1 obesity, 135 (17.8%) had Class 2 obesity, and 122 (16.1%) had Class 3 obesity. When adjusted for confounders, those with Class 1 obesity were 54% less likely to achieve serum levels deemed therapeutic for seizure prophylaxis compared with normal BMI counterparts. Meanwhile, those with Class 2 or 3 obesity were 90% less likely. Linear regression models also demonstrated an inverse association between BMI and post-bolus serum magnesium levels.
Conclusion Increasing BMI has a significant effect on post-bolus serum magnesium levels regardless of standard loading dose used. Immediately after bolus administration, obese gravidas are significantly less likely to reach levels effective for eclamptic seizure prophylaxis. When considering which bolus to administer in an obese gravida, it may be more beneficial to choose a 6 g load.

Subjectivity and algorithmic imaginaries: the algorithmic other
Authors: Gandini Alessandro , Gerosa Alessandro , Giuffrè Luca , Keeling Silvia 
Published: November 2023

AbstractThe notion of algorithmic imaginaries has been affirmed as an important heuristic to understand the functioning of social media algorithms through the account of users’ individual and collective experiences. Yet, the relationship between algorithmic imaginaries and users’ subjective engagement with social media, considering the personalised circulation of content on these platforms, demands further expansion. To fill this gap, the article introduces the notion of the algorithmic other, conceived as complementary to that of algorithmic imaginaries. Building on small-scale qualitative research on everyday online news consumption in Italy, we show how users engage in ‘othering’ the algorithm(s), which we describe as a process of counter-subjectivation that users enact in response to their own individuation as digital and data subjects. We explore the main dimensions of this process, arguing that it represents a by-product of the intense personalisation of their everyday user experience.
Scale transformation of place brands: a visual study of Xinhepu, Guangzhou
Authors: Zhang Jiayin , Lin Mingliang , Wang Min , Lin Yinbin 
Published: November 2023

AbstractPlace branding has become a popular strategy to promote place visibility and place image communication and gains attention in the field of city planning, geography, and place management. The contribution of geographical knowledge has been emphasized and discussed in recent place branding studies, including the role of geographical scale in branding strategies and management. However, current research mainly places the issues of scale from the top-down perspective of branding governance, and the bottom-up processes based on local culture and embodied experiences are overlooked. Drawing on participatory-based visual methodology, in the article, a combination of self‐directed photography, photo evaluation, eye-tracking experiment, and interview are employed to the scale transformation performance of place brands from the perspective of embodied experience. Taking Xinhepu in Guangzhou, China as a case study, the results show that both residents and nonresidents do not limit their perception of the Xinhepu brand to a microscale space but point to the city of Guangzhou. Specifically, the process of scale transformation of place brands is characterized by the interaction of temporal and spatial factors that provide possibilities for scale transformation. The physical landscape in space plays a role in place branding, while in time scale, Xinhepu connects Guangzhou’s past and present and is a microcosm of the city’s image and historical development; thus, in people’s embodied perception, Xinhepu can be transformed into a city brand through place culture creation. The article can provide a new explanation for the construction of place branding at multiple geographical scales and explore how the body’s unconscious, nonrepresentational rhythms play a role in place brand scale transformation.

Published: November 2023

A great deal of effort has been recently devoted to the study of dielectric relaxation processes in ferroelectric nematic liquid crystals, yet their interpretation remains unclear. In this work, we present the results of broadband dielectric spectroscopy experiments of a prototypical ferroelectric nematogen in the frequency range 10 Hz–110 MHz at different electrode separations and under the application of DC bias fields. The results evidence a complex behavior in all phases due to the magnitude of polar correlations in these systems. The observed modes have been assigned to different relaxation mechanisms based on existing theoretical frameworks.

Context Formulating diets using agro-industrial by-product concentrates to increase the growth performance and cost efficiency of Ongole crossbred bulls. Aims This study was conducted to evaluate the inclusion of agro-industrial by-products of dried cassava powder (DCP), mixed copra meal (CM), palm kernel cake (PKC) and soybean hull (SBH) into rations at low and high levels of feeding on bull liveweight gain and farmer profitability. Methods Fifty Ongole crossbred bulls with an initial bodyweight (BW) of 227 ± 66.5 kg and aged between 12 and 18 months, were arranged in a randomised complete-block design of five treatments, with 10 heads per treatment. The control group (T0) was provided the current feeding system (CFS) fed ad libitum. The supplemented treatments consisted of CFS ad libitum + concentrate (50% DCP, 25% CM, 25% PKC) at 1% BW/day (T1), CFS ad libitum + concentrate (50% DCP, 25% CM, 25% SBH) at 1% BW/day (T2), CFS ad libitum + concentrate (50% DCP, 25% CM, 25% PKC) at 2% BW/day (T3), CFS ad libitum + concentrate (50% DCP, 25% CM, 25% SBH) at 2% BW/day (T4). The experiment was conducted for 12 weeks. Key results The BW gain over 12 weeks (kg) for T0, T1, T2, T3 and T4 was 39.5, 56.2, 68.9, 57.5 and 62.1 kg respectively. The income over feed cost was significantly higher in T2. Conclusions Supplementation with by-products increased bull liveweight gain compared with current feeding practices. A concentrate supplementation of DCP mixed with CM and SBH at 1% BW/day was the most effective and profitable supplementation method to increase income of farmers in this district and there was no advantage of increasing the level of supplement. Implications A combination of DCP, CM and SBH to form a concentrate supplement and fed at 1% BW/day will increase bull liveweight gain and income of farmers.
Constitutive representation of womanhood

Published: November 2023

Abstract
This article analyzes the speeches of Turkish female parliamentarians during the headscarf debate. We examine how
deputies with different political and ideological predilections discursively construct women’s rights and employ legitimation
strategies to validate their policy position. The findings reveal that on the one hand, the female deputies use different
legitimation strategies to justify arguments for or against the use of headscarves in the public sector. On the other hand, they
embed the headscarf debate into the broader political goals they pursue in a polarized political setting. They deploy legitimation
strategies around the headscarf debate to rationalize future policy on issues ranging from the expansion of human rights and
democracy to the change of the type of political regime.
Waveform systematics in identifying strongly gravitationally lensed gravitational waves: posterior overlap method
Authors: Garrón Ángel , Keitel David 
Published: November 2023

Abstract
Gravitational lensing has been extensively observed for electromagnetic signals, but not yet for gravitational waves (GWs). Detecting lensed GWs will have many astrophysical and cosmological applications, and becomes more feasible as the sensitivity of the ground-based detectors improves. One of the missing ingredients to robustly identify lensed GWs is to ensure that the statistical tests used are robust under the choice of underlying waveform models. We present the first systematic study of possible waveform systematics in identifying candidates for strongly lensed GW event pairs, focusing on the posterior overlap method. To this end, we compare Bayes factors from all posteriors using different waveforms included in GWTC data releases from the first three observing runs (O1–O3). We find that waveform choice yields a wide spread of Bayes factors in some cases. However, it is likely that no event pairs from O1 to O3 were missed due to waveform choice. We also perform parameter estimation with additional waveforms for interesting cases, to understand the observed differences. We also briefly explore if computing the overlap from different runs for the same event can be a useful metric for waveform systematics or sampler issues, independent of the lensing scenario.
The q-metric naked singularity: a viable explanation for the nature of the central object in the Milky Way
Authors: Lora-Clavijo F D , Prada-Méndez G D , Becerra L M , Becerra-Vergara E A 
Published: November 2023

Abstract
In this work, we investigate whether the compact object at the center of the Milky Way is a naked singularity described by the q-metric spacetime. Our fitting of the astrometric and spectroscopic data for the S2 star implies that similarly to the Schwarzschild black hole, the q-metric naked singularity offers a satisfactory fit to the observed measurements. Additionally, it is shown that the shadow produced by the naked singularity is consistent with the shadow observed by the Event Horizon Telescope collaboration for Sgr-A*. It is worth mentioning that the spatial distribution of the S-stars favors the notion that the compact object at the center of our Galaxy can be described by an almost static spacetime. Based on these findings, the q-metric naked singularity turns up as a compelling candidate for further investigation.

Published: November 2023

Abstract
Ruthenium (Ru) doped antimony tungstate microflowers, prepared through hydrothermal process, have been investigated for simultaneous adsorption and photocatalysis. The pattern of evolution of microflower structures, however, can be tailored by the synthesis period. This change is observed from the field effect scanning electron microscope and transmission electron microscope images. A possible mechanism behind this morphological change has been developed. An argument based on the zeta potential may be responsible for this distinct morphology due to the strong electrostatic interactions. The variation of a particular x-ray diffraction peak corresponding to the plane

with variation of Ru doping percentage shows the decrease in crystallinity along the perpendicular direction to this plane. Besides, the optimum Ru doping percentage is evaluated on the basis of photocatalytic efficiency towards methylene blue (MB) degradation under visible light. The highest dye removal efficiency is observed for 2% Ru doped Sb2WO6 (SWO) adsorbing 97% of the MB dye followed by photocatalytic degradation of almost 64% of the remaining dye in 80 min. Furthermore, using different dyes, it is concluded that Ru–SWO showcases high adsorption toward the cationic dyes while it neither adsorbs the anionic dye nor displays photocatalytic degradation.

Published: November 2023

Abstract
In order to improve the performance of the sonar system, a stepped broadband high-sensitivity hydroacoustic transducer is developed. Through theoretical analysis and finite element simulation, the feasibility of expanding the operating bandwidth and improving the sensitivity of the monometallic plate stepped piezoelectric material sensitive element is analyzed, and the dimensional parameters of this sensitive element are optimized. Compared with the traditional composite material, the sensitive element has excellent piezoelectric performance, with broadband and high sensitivity properties. The monometallic plate stepped piezoelectric material transducer and the same size stepped composite transducer were prepared, and their hydroacoustic performance was tested. The test results show that the monometallic plate stepped piezoelectric material transducer has far superior sensitivity performance than the same size stepped composite transducer and also has broadband performance. The peak transmits voltage response of the monometallic plate stepped transducer is 166 dB, and the −3 dB bandwidth reaches 60 kHz; the peak receives sensitivity is −183 dB, and the −3 dB bandwidth reaches 55 kHz, which can effectively improve the performance of the sonar system.

Abstract
Using a convenient and low-cost plasma-enhanced chemical vapor deposition technique, uniform Ga2O3 thin films were hetero-grown on c-plane sapphire substrates at different temperatures, with a root mean square roughness as low as 2.71 nm and a growth rate of up to 1121.30 nm h−1; and then the solar-blind UV photodetection performances were discussed in detail. Metal-semiconductor-metal solar-blind UV photodetectors (PDs) based on the five Ga2O3 films prepared at different temperatures exhibit ultra-low dark currents (I
dark) ranging among 22–168 fA. Under the illumination of 254 nm UV light, the PD prepared by the film grown at 820 °C possesses the highest performance, with a high photo-to-dark current ratio of 1.47 × 105, a low rise/decay time of 0.067/0.13 s, a specific detectivity (D
*) of 3.56 × 1012 Jones, and a linear dynamic range of 92.89 dB. Overall, the results in this work may well provide a referable method for growing cost-effective and ultralow-noise Ga2O3 thin films, as well as achieving decent solar-blind UV sensing applications.
