Context. One of the ultimate goals of the ESA Ariel space mission is to shed light on the formation pathways and evolution of planetary systems in the Solar neighbourhood. Stellar elemental abundances are the cipher key to decode planetary compositional signatures. This makes it imperative to perform a large chemical survey not only of the planets, but their host stars as well.
Aims. This work is aimed at providing homogeneous chemical abundances for C, N, and O among a sample of 181 stars belonging to Tier 1 of the Ariel mission candidate sample.
Methods. We applied the spectral synthesis and equivalent width methods to a variety of atomic and molecular indicators (C I lines at 5052 and 5380.3 Å, [O I] forbidden line at 6300.3 Å, C2 bands at 5128 and 5165 Å, and CN band at 4215 Å) using high-resolution and high signal-to-noise spectra collected with a range of spectrographs.
Results. We determined carbon abundances for 180 stars, nitrogen abundances for 105 stars, and oxygen abundances for 89 stars. We analysed the results in the light of the Galactic chemical evolution and in terms of the planetary companion properties. We find that our sample essentially follows standard trends with respect to the metallicity values expected for the [C/Fe], [N/Fe], and [O/Fe] abundance ratios. The proportion between carbon and oxygen abundances (both yields of primary production) is consistent with a constant ratio as [O/H] increases. Meanwhile, the abundance of nitrogen tends to increase with the increasing of the oxygen abundance, supporting the theoretical assumption of a secondary production of nitrogen. The [C/N], [C/O], and [N/O] abundance ratios are also correlated with [Fe/H], which might introduce biases in the interpretation of the planetary compositions and formation histories when host stars of different metallicities are compared. Finally, we provide relations that can be used to qualitatively estimate whether the atmospheric composition of planets is enriched (or otherwise) with respect to the host stars.
Zehn Jahre Hypoglossusnerv-Stimulation bei obstruktiver Schlafapnoe – ein systematischer Literaturreview
Authors: Habetha Susanne , Sauermann Sven , Müller Stefanie , Gottschalk Gerd 
Published: June 2024

Zusammenfassung
Zielsetzung Es soll die Bedeutung der Hypoglossusnerv-Stimulation (HGNS) als Behandlungsmethode der obstruktiven Schlafapnoe (OSA) im deutschen Versorgungskontext dargestellt werden, um im Ergebnis eine bessere Einschätzung darüber zu erhalten, in welcher Weise Patienten, die bisher nicht ausreichend versorgt sind, von der HGNS profitieren können.

Methoden Anhand einer systematischen Literaturauswertung in den Literaturdatenbanken Medline und Cochrane Library, in die unterschiedliche Stimulationstechnologien eingeschlossen wurden, wurde die Wirksamkeit der HGNS mithilfe patientenrelevanter Endpunkte (Tagesschläfrigkeit, Lebensqualität), die Therapieadhärenz sowie der Apnoe-Hypopnoe-Index (AHI) und Oxygen Desaturation Index (ODI) eingeschätzt. Die Sicherheit der Behandlungsmethode wurde anhand der unerwünschten Ereignisse (UE) überprüft.

Ergebnisse Einschluss und Auswertung von 33 Publikationen: 2 randomisierte kontrollierte Studien (RCTs, Level Ib), 1 Studie Level IIb (n = 1) und 30 Studien Level IV mit einer Studiendauer von bis zu 60 Monaten. In den RCTs zeigten sich für die Tagesschläfrigkeit und Lebensqualität unter Anwendung der HGNS bessere Werte als in der Kontrollgruppe. AHI und ODI wiesen unter Placebostimulation bzw. Therapieentzug in den RCTs eine Verschlechterung auf. Zur Adhärenz wurden auch im Langzeitverlauf konsistent hohe Werte berichtet. Schwere UE unter HGNS waren selten und konnten meist durch eine Repositionierung von Elektroden oder einen Austausch von Geräteteilen beseitigt werden. Andere UE waren überwiegend vorübergehend oder konnten durch nicht-invasive Maßnahmen behoben werden. Alle untersuchten Parameter zeigten gleichgerichtete Ergebnisse in den ausgewerteten Studien. Die Ergebnisse von unterschiedlichen Stimulationssystemen sind in Art und Ausmaß vergleichbar.

Schlussfolgerung Basierend auf einer umfangreichen
Literaturauswertung unterstreichen konsistente Daten die Bedeutung der HGNS als wirksame und
sichere Behandlung der OSA nach erfolgloser CPAP-Behandlung. Die Auswertung lässt darüber
hinaus erkennen, dass die unterschiedlichen Stimulationssysteme eine an den
patientenindividuellen Erfordernissen ausgerichtete Therapie ermöglichen. Eine zukünftige
systematische Auswertung von Real-World-Daten zur Anwendung der HGNS erscheint notwendig, um
zusätzliche Erkenntnisse über die Relevanz der Methode in der klinischen Routine zu erhalten.

Published: June 2024

Abstract
Background Autism spectrum disorder (ASD) is a pervasive developmental disorder of unknown aetiology. There is a growing prevalence of ASD globally. Currently, there are no specific treatment that can address the core impairments of ASD.
Case Summary A 5-year male child was brought to outpatient department with complaints of irritability, restlessness, howling, repeating words spoken to him, repeating phrases, hand flapping, self-hurting and hurting others, climbing stairs repeatedly, repeated drawing of squares everywhere, poor social interaction, poor peer-play and inappropriate playing with toys. The case was diagnosed as ASD and was assessed with the autism treatment evaluation checklist (ATEC) at baseline and follow-up visits. The case was treated with Theridion currasavicum in centesimal scale. ATEC score at baseline of 118 turned to 69 at the 12th month and 42 after 24 months of treatment. The remedy was repeated during monthly visits in ascending potencies. The child improved in the domains of social interaction, communication, repetitive stereotype movements, restricted interests and general health. The likelihood of causal relationship between intervention and outcome has been discussed as per modified Naranjo criteria for homoeopathy. This case report highlights the usefulness of the group approach and aetiological prescription as one way of arriving at the similimum in children with autism.
Predictive Factors for Regression versus Progression of Nonevacuated Posttraumatic Acute Extradural Hematoma
Authors: Elkholy Hany , Elnoamany Hossam , Hussein Mohamed Adel 
Published: June 2024

Abstract
Study Design This study was a retrospective study conducted from October 2020 to October 2022 on 106 posttraumatic patients with acute extradural hematomas (EDHs) who were initially planned for conservative treatment. 74 patients had spontaneous EDH regression (EDHR), while 32 patients developed EDH progression (EDHP) and were shifted for surgery. The two groups were statistically compared regarding the different demographic, clinical, and radiographic factors to identify the significant predictors for regression versus progression of acute posttraumatic EDH.
Objectives Conventionally, urgent evacuation is the accepted management for EDH. However, several recent reports have described successful conservative management in selected patients. There are no adequate clues to verify patients who will have spontaneous EDHR from those at risk for EDHP and delayed surgery. The main objective of this study was to identify the significant predictors for possible regression versus progression of acute posttraumatic EDH initially planned for nonsurgical treatment.
Materials and Methods A retrospective study conducted over 2 years, included 106 head trauma patients with acute EDH, who were admitted to our department and were initially planned for conservative treatment. Various demographic, clinical, and radiographic factors were analyzed to verify the significant predictors for spontaneous EDHR (EDHR group) versus EDHP and subsequent surgical evacuation (EDHP group).
Results The mean age was 20.37 ± 12.712 years and the mean Glasgow Coma Scale score (GCS) was 12.83 ± 2.113. Total 69.8% of patients showed spontaneous EDHR, while 30.2% developed EDHP and were shifted for surgical evacuation. Statistical comparison showed that higher GCS (p = 0.002), frontal location (p = 0.022), and concomitant fissure fracture (p =  0.014) were the significant predictors for EDHR, while younger age (p = 0.006), persistent nausea/vomiting (p = 0.046), early computed tomography (CT) after trauma (p = 0.021), temporal location (p < 0.001), and coagulopathy (p = 0.001) were significantly associated with EDHP.
Conclusion Patients with traumatic EDH fitting the criteria of initial nonsurgical treatment necessitates 48 hours of close observation and serial CT scans at 6, 12, 24, and 48 hours to confirm the regression or early detect the EDHP. Patients with high GCS, frontal hematomas, and associated fissure fracture are at low risk for EDHP. Increased alertness is mandatory for young age and patients with persistent nausea/vomiting, early CT scan, temporal hematomas, or coagulopathy.

Authors: Bal Sangram , Jain Surendra , Acharya Sushil , Gupta Ashok 
Published: June 2024

Abstract
Background Magnesium is considered to have important role in cytotoxic and reperfusion pathways, deficiency of which may lead to secondary brain injuries; thus, hypomagnesemia is thought to be detrimental in traumatic brain injury (TBI) patients. The aim of this study was to evaluate the relationship between serum ionic magnesium level and neurological outcome in severe TBI patients.
Materials and Methods Eighty-four patients with severe TBI aged between 20 and 80 years admitted within 24 hours of injury included in our study. All patients were divided into two categories on the basis of initial serum magnesium levels as low serum magnesium level and normal serum magnesium level. Data was collected on the basis of age, gender, Glasgow Coma Scale (GCS) at the time of admission, and neurological outcome evaluation done on the basis of Glasgow Outcome Scale (GOS) at the end of 6 months.
Results Among the total patients, 32 patients had low serum magnesium level (< 1.6 mg/dL) at the time of admission. About 87.5% patients with low serum magnesium level had poor neurological outcome as compared to 12.5% of patients (p < 0.001) had good neurological outcome evaluated on the basis of GOS. Logistic regression model identified low Mg level (odds ratio = 6.593, p = 0.002) and GCS score less than 5 (odds ratio = 3.099, p = 0.028) as independent predictors of TBI.
Conclusion Hypomagnesemia seems to be an independent prognostic marker in severe TBI that can lead to poorer outcomes.

Published: June 2024

AbstractEnhancing the quality and safety of exported agricultural products and improving export competitiveness is the key to establishing enhanced competitive advantages in agricultural products, developing a trade powerhouse and realising high-quality development of agriculture. This paper uses the data of Chinese listed companies and Chinese Customs from 2007 to 2016 to discuss the effect and mechanism of digital transformation of enterprises on the quality and safety level of export agricultural products by using the staggered differential method. The study shows that (1) Enterprise digital transformation effectively improves the quality and safety of exported agricultural products, and this result holds after endogeneity, placebo and multiple robustness tests; (2) Heterogeneity analyses reveal that the quality and safety effect of enterprise digital transformation is greater for exporting to developed countries’ markets, non-state-owned enterprises and enterprises in the eastern region, in addition to bulk agricultural products and consumer-oriented agricultural products; (3) Mechanism analyses shows that enterprise digital transformation raises the quality and safety of exported agricultural products through technological innovation, product tracing, information sharing and quality assurance effects.
The quick termination of verbal conflicts expressed through disagreement
Authors: Pütz Ole , Hassan Hafsa 
Published: June 2024

Abstract
This paper considers verbal conflicts at the workplace and asks how team members negotiate conflict termination. Our corpus consists of meetings where computer scientists discuss the progress of projects they are working on, a context where conflict resolution is crucial for the continuation of work. Following the literature, we define conflicts as continued disagreement. The analysis focuses on conflict termination formats that show whether a conflict can be resolved as well as episode length and disagreement mitigation that indicate the severity of the conflict. Power relations among participants are also discussed. Our results show that most conflicts end after two or three disagreements. Among the termination formats, submission is the most frequent, followed by stand-off and compromise. We further show that participants minimize conflicts by concluding them as soon as someone indicates their unwillingness to concede, whereas the pattern of conflict minimization varies with the termination format that participants negotiate.
Variational Monte Carlo study of stripes as a function of doping in thet−t′Hubbard model
Authors: Lechiara Antonio , Marino Vito , Tocchio Luca F 
Published: June 2024

AbstractWe perform variational Monte Carlo simulations of the single-band Hubbard model on the square lattice with both nearest (t) and next-nearest (t′) neighbor hoppings. Our work investigates the consequences of increasing hole doping on the instauration of stripes and the behavior of the superconducting order parameter, with a discussion on how the two phenomena affect each other. We consider two different values of the next-nearest neighbor hopping parameter, that are appropriate for describing cuprate superconductors. We observe that stripes are the optimal state in a wide doping range; the stripe wavelength reduces at increasing doping, until stripes melt into a uniform state for large values of doping. Superconducting pair–pair correlations, indicating the presence of superconductivity, are always suppressed in the presence of stripes. Our results suggest that the phase diagram for the single-band Hubbard model is dominated by stripes, with superconductivity being possible only in a narrow doping range between striped states and a nonsuperconducting metal.
Large dynamic scissoring mode displacements coupled to band gap opening in the cubic phase of the methylammonium lead halide perovskites

Published: June 2024

Abstract
Hybrid perovskites are a rapidly growing research area, having reached photovoltaic power conversion efficiencies of over 25%. There is a increasing consensus that the structures of these materials, and hence their electronic structures, cannot be understood purely from the time and space averaged crystal structures observable by conventional methods. We apply a symmetry-motivated analysis method to analyse x-ray pair distribution function data of the cubic phases of the hybrid perovskites MAPbX
3 (X = I, Br, Cl). We demonstrate that, even in the cubic phase, the local structure of the inorganic components of MAPbX
3 (X = I, Br, Cl), are dominated by scissoring type deformations of the PbX
6 octahedra. We find these modes to have a larger amplitude than equivalent distortions in the A-site deficient perovskite ScF3 and demonstrate that they show a significant departure from the harmonic approximation. Calculations performed on an inorganic perovskite analogue, FrPbBr3, show that the large amplitudes of the scissoring modes are coupled to a dynamic opening of the electronic band gap. Finally, we use density functional theory calculations to show that the organic MA cations reorientate to accommodate the large amplitude scissoring modes.
SFD-SLAM: a novel dynamic RGB-D SLAM based on saliency region detection
Authors: Gong Can , Sun Ying , Zou Chunlong , Jiang Du , Huang Li , Tao Bo 
Published: June 2024

Abstract
In dynamic environments, several simultaneous localization and mapping (SLAM) systems effectively utilize optical flow fields to distinguish dynamic from static feature points. Commonly, these systems leverage the amplitude information within the optical flow field to develop adaptive thresholding segmentation models for identifying dynamic scene regions. Nevertheless, designing adaptive thresholding models typically necessitates meticulous planning and extensive experimentation. This study introduces a dynamic RGBD SLAM system, SFD-SLAM, which innovates by employing a saliency detection network for the direct extraction of dynamic regions via scene flow. This approach notably streamlines the design process associated with conventional adaptive thresholding models. Furthermore, SFD-SLAM incorporates a geometric module that merges depth residuals with hyperpixel segmentation to enhance the refinement of the dynamic mask. This is followed by integration with FCM clustering for the precise identification of moving objects. The efficacy of SFD-SLAM is assessed using the widely recognized TUM dynamic dataset. Experimental results demonstrate that the proposed system surpasses DGFlow-SLAM, which relies on an adaptive thresholding model for dynamic object segmentation, in terms of trajectory accuracy. It also achieves comparable localization accuracy to DynaSLAM. Moreover, SFD-SLAM maintains robust tracking capabilities, even in scenarios where DynaSLAM experiences tracking loss, thereby augmenting the robustness of RGBD-SLAM in dynamic settings.
Promoting abstract thinking and scientific argumentation in the teaching of physics
Authors: Sabín Juan 
Published: June 2024

Abstract
Abstract thinking and scientific argumentation are two of the more important high-order cognitive skills that students at secondary level need to develop in the learning of physics. In this paper a new methodology based on constructivism’s view of education is presented by using counterintuitive experiments under a POE strategy (Predict, Explain, Observe). The experiments consist in a race of two soda can, one of them previously shaken, over an inclined plane; and the movement of a double cone object, built by two joined funnels, over two convergent inclined rails. The unexpected outcome of both experiments challenges the prior ideas of the students and provokes a higher engagement in their learning process. The results of a pilot experience applying this methodology suggest that using counterintuitive experiments under PEO strategy is an effective methodology to introduce the teaching of abstract concepts as moment of inertia and centre of mass. It also helps identifying students’ prior knowledge, promoting the use of scientific reasoning, and training students in the activation of their abstraction skills.

Published: June 2024

Abstract
Reducing the negative impact of magnetic vortex motion is a long-term challenge for superconducting applications. Here, we conduct an in-depth investigation on the response of NbN nanowires on applied magnetic fields with the transverse size down to 10 nm. It is found that the vortex-free state can sustain under field up to 9 T in the sample of this dimension, demonstrating a unique approach to reduce the negative effects of flux motion in applications. Such a conclusion is further confirmed by the vanished flux-low instability velocity. Moreover, the upper critical field of the NbN nanowires reveals clear anisotropic features, which can be interpreted based on the framework of the Ginzburg–Landau model. Our results provide important information for understanding the behavior of nanoscale superconducting materials under magnetic fields, which is significant for the application of superconducting micro/nano devices.

Published: June 2024

Abstract
NdFeAs(O,H) microstrips with line widths of about 1–5 µm were fabricated by photolithography and Ar-ion dry etching. The microstrips were fabricated under two different etching conditions: 25 min etching at a power of 20 W (long duration, low power) and 3 min etching at 100 W (short duration, high power). For both conditions, the narrowest microstrips, which were 0.9 µm in width, retained high critical temperatures of about 85% of those before microfabrication. Further, the 0.9 µm microstrip fabricated under the high-power, short-duration condition exhibited a high critical current density (J
c) of more than 4 MA cm−2 at 4 K. However, J
c of the microstrip fabricated under the low-power, long-duration condition was somewhat lower. Our analysis suggests that the edges of the microstrips were damaged more than twice as wide as those of the microstrips fabricated under the high-power, short-duration condition. This indicates that a short duration is more effective to reduce the damage than using a lower etching power.

Published: June 2024

Abstract
Water pollution issues are becoming more and more serious, particularly those caused by heavy metal ions. In this paper, β-cyclodextrin (β-CD) and polyvinylidene fluoride (PVDF) were chosen to prepare composite films by electrospinning technology. The microstructure, crystalline phases, mechanical properties, porosity, and adsorption performance of β-CD/PVDF composite films were analyzed. The results show that the β-CD/PVDF composite fibers were smooth and randomly deposited to form an interconnected three-dimensional network structure. The diameter of the β-CD/PVDF composite fibers ranged from 0.22 to 0.33 μm, and the fiber diameter distribution was uniform. The maximum porosity was 79.56% when the content of β-CD was 2%. After adding the β-CD, the tensile strength increased to 13.33 MPa and the elongation at break increased to 14.20% as well. With the β-CD content increasing, the adsorption capacity of the β-CD/PVDF composite films for Cu2+ increased to 182.65 mg g−1. In addition, the second-order kinetic model was suitable to describe the adsorption process, and the chemical adsorption was the predominant mechanism of the adsorption process due to the presence of β-CD. The results suggest that the β-CD/PVDF composite films may be a potential adsorbent for Cu2+ adsorption.
