Authors: Jakob Till F , Aschendorff Antje , Arndt Susan 
Published: July 2024

ZusammenfassungDie Single-Sided Deafness (SSD) ist eine einseitige Taubheit mit erhaltener Funktion des nicht betroffenen Ohres. Sie kann angeboren (z.B. durch eine Aplasie des Hörnervs) oder postlingual erworben sein. Die Patienten leiden unter einer eingeschränkten Schalllokalisation und Problemen im Störgeräusch. Es gibt verschiedene Therapieoptionen – nur mit einem Kochleaimplantat (Cochlear Implant, CI) kann jedoch ein binaurales Hören erreicht werden.

AbstractV-flow is a dynamic ultrasound technique that visualizes perfusion patterns by displaying dynamic arrows that change in response to the flow of erythrocytes. Furthermore, it provides quantitative values for the maximum and mean velocity of blood flow as well as a percentage value for turbulence. The aim was to enhance the preoperative diagnostic accuracy of thyroid lesions by combining V-flow with established ultrasound modes.B-mode, CCDS, elastography, CEUS, and V-flow were performed on 101 patients. After the ultrasound examination, every nodule was confirmed as benign or malignant via histopathology. The Kruskal–Wallis test, ROC curve, and binary logistic regression were used for the statistical analysis.93 benign regressive thyroid nodules and 8 carcinomas were included in this study. The average mean velocity value for benign lesions was measured at 19.5 cm/s and at 10.7 cm/s for malignant lesions (p = 0.039). The average turbulence percentage was 26.1% for benign nodules and 46.7% for carcinomas (p = 0.016). Carcinomas exhibited a slower and more turbulent perfusion pattern compared to benign tumors. A V-flow-centered system achieves a sensitivity of 100.0% and a specificity of 84.9% in predicting malignancy. This system could have reduced the number of unnecessary thyroid surgeries for benign lesions in our patient group by 70%.The capillary perfusion of thyroid nodules represents a significant indicator of its status. By analyzing the velocity and turbulence level of microvascular blood flow, V-flow offers promising prospects for accurately distinguishing between benign and malignant thyroid lesions. When integrated into a comprehensive multimodal sonographic imaging approach, V-flow further enhances diagnostic accuracy.

Objective Neonatal sepsis has been established as a risk factor for retinopathy of prematurity (ROP) but previous meta-analyses have predominately focused on late-onset sepsis (LOS). This meta-analysis aims to explore the association between early-onset sepsis (EOS) and the risk of ROP.
Study Design Observational studies reporting (unadjusted) data on proven EOS in neonates with ROP were included. PubMed, Embase, and Cochrane Library were searched. Proven EOS was defined as a positive blood or cerebrospinal fluid culture. Effect sizes were calculated by using logistic random-effects models and meta-regression analyses. Primary outcomes were any stage ROP and severe ROP (≥stage 3, type I, aggressive [posterior] ROP, plus disease or requiring treatment). Potential confounders explored were gestational age at birth, birth weight, small for gestational age, maternal steroid use, necrotizing enterocolitis, LOS, and mechanical ventilation duration.
Results Seventeen studies reporting the incidence of proven EOS in neonates with ROP were included. Proven EOS showed no significant association with any stage ROP (odds ratio [OR] = 1.90; 95% confidence interval [CI]: 0.96–3.79, p = 0.067) but heterogeneity between studies was significantly high. Neonates with proven EOS had an increased risk for severe ROP (OR = 2.21; 95% CI: 1.68–2.90), and no significant confounders influencing this effect size were found in the meta-regression analysis.
Conclusion Neonates with proven EOS are at increased risk of severe ROP. Neonatologists need to be aware that EOS is an early predictor of ROP and should adapt their policy and treatment decisions where possible to reduce ROP.

Imaging Spectrum in Pulmonary Tuberculosis
Authors: Bhatia Harsimran , Kaur Ravinder , Kaur Irwinjit , Garg Karan 
Published: July 2024

AbstractPulmonary tuberculosis is one of the most common pulmonary infections prevalent in our country. Although definitive diagnosis is microbiological, characteristic imaging features help in establishing a certain diagnosis in most of the cases. While chest radiography remains the primary screening tool, computed tomography helps in clinching the diagnosis with a spectrum of findings described on cross-sectional imaging. The radiologist must be familiar with the features denoting potential complications and differential diagnosis to aid better treatment planning and case prognostication. This article describes in detail the imaging features of pulmonary tuberculosis, active disease, disease sequelae, and complications.
Territorial disputes and international law: reclaiming the sui generis nature of arbitration
Authors: Siniver Asaf 
Published: July 2024

AbstractThis study aims to bridge the disciplinary gap between IR and international law in the study of conflict resolution by highlighting the sui generis nature of arbitration as a hybrid political-legal method of dispute settlement that has been lost over the years due to its overly judicialized application. It reclaims the unique nature of arbitration by demonstrating its capacity to enable state flexibility and autonomy which can be found in mediation, whilst providing a final and legally binding solution, which is commonly associated with adjudication. Utilizing the case study of the Beagle Channel arbitration between Chile and Argentina (1971–77), this study demonstrates that a key reason behind the general misuse and disuse of arbitration is the failure of states to capture its sui generis nature and instead adopt an overly judicialized approach.
ClSO and ClSO2 photochemistry: Implications for the Venusian atmosphere
Authors: Trabelsi Tarek , Lipson Juliette , Francisco Joseph S. 
Published: July 2024

The electronic structure and spectroscopy of ClSOx (x = 1 and 2) isomers were investigated using coupled cluster theory and multireference interaction methods. In this study, the equilibrium geometry and harmonic vibrational frequencies of these isomers in their ground electronic state were shown. Our analysis of the vertical excitation energy and potential energy surface showed the photochemical instability of ClSO for wavelengths below 280 nm. Furthermore, the photodissociation of ClSO was unlikely to cause the formation of diatomic ClS. At the same time, ClSO could form atomic chlorine and SO as a result of photodissociation through the repulsive states. In the case of ClSO2, a novel weakly bound Cl–SO2 isomer was identified, indicating the potential influences on the chlorine and SO2 reactions. The potential energy surface of the most stable ClSO2 isomer also indicated the potential production of SO2 in both its ground and excited states. In addition, the electronic spectrum of ClSO2 was predicted to be broad, with numerous significant peaks in the near-UV‒Vis range. Valuable new insights into the chemical role of chlorine and sulfur in Venus's atmosphere were provided, along with a discussion of a potential mechanism contributing to the H2O and SO2 depletion in Venus's atmosphere.
China’s real estate agents’ persuasion realizations on WeChat Moments
Authors: He Jianyou , Xia Dengshan 
Published: July 2024

Abstract
Persuasion is a well-documented language phenomenon in the fields of rhetoric, communication, and sociopsychology.
However, there is still a need for further research into persuasion on social media from a pragmatic perspective. The current
research contributes to the existing literature on persuasion, particularly in virtual environments, by examining the tactics of
online persuasion with a dataset of 409 excerpts from WeChat Moments. It examines the frequency and percentage of persuasive
strategies deployed by fourteen Chinese real estate agents. Additionally, a qualitative analysis of each tactic is conducted,
supported by specific examples. The findings indicate that, in increasing order of frequency, persuasion attempts on the
participants’ WeChat Moments are primarily realized through rational, ethos, and emotional appeals. The determinants of this
strategic inclination are examined with respect to the anonymity afforded by the Internet, media effect, community of practice and
Chinese cultural particulars.

Published: July 2024

Abstract
In the process of industrial production, product defects often arise due to improper operations among other reasons, rendering the detection of such flaws an indispensable procedure. However, the vast array of defect types, coupled with their complex characteristics, poses ongoing challenges for contemporary defect detection algorithms within industrial settings. To solve this problem, the present study introduces an enhanced steel surface defect detection model based on the modified YOLOv8 algorithm-termed the MAA-YOLOv8 model-to augment the accuracy and practicality of the algorithm. Initially, a multi-head attention mechanism was incorporated into the C2f to bolster the feature extraction capabilities within the backbone network and diversify the attention maps. Secondly, in the neck structure, we design a multi-channel feature fusion module (McPAN) to solve the problem of balance between computational efficiency and the ability to capture useful features. A series of experiments conducted on the NEU-DET dataset reveal that the MAA-YOLOv8 model achieves a mean Average Precision (mAP) of 94.4%, representing an enhancement of 11.1% over the original YOLOv8s model. The MAA-YOLOv8 model proposed in this study substantially elevates the performance of steel surface defect detection while ensuring the speed of detection.
Phase space reconstruction technique for beam optimization in the Low Energy High Intensity Proton Accelerator (LEHIPA)
Authors: Priyadarshini Pallavi , Mathew Jose V , Mathad Deepak N , Kumar Rajesh 
Published: July 2024

Abstract
The Low Energy High Intensity Proton Accelerator (LEHIPA) has been commissioned to the design energy of 20 MeV at BARC, India. The low energy beam transport (LEBT) channel of LEHIPA consists of two solenoids and drift spaces for matching the 50 keV proton beam from the ECR ion source (ECR-IS) to the RFQ. The ion beam extracted from the ECR-IS also contains molecular species like H2
+ and H3
+. Proton fraction in the beam is found to degrade slowly with time due to surface contamination of the plasma chamber and this reduction in proton beam current has implications for longitudinal and transverse beam dynamics. Hence, it becomes important to characterise the beam at different proton fraction levels to understand the end-to-end beam dynamics of LEHIPA. Computed Tomography (CT) technique has been used for the beam phase-space reconstruction in LEHIPA, using a Python program, incorporating the feature of filtering secondary species from the beam profiles measured using slit scanners in the LEBT. Simultaneous Algebraic Reconstruction Technique (SART) is used in the reconstruction since it is identified to be a better technique for a limited number of projections. The reconstruction program is benchmarked with the TraceWin beam dynamics code and implemented on the measured beam profiles to recreate the phase space distribution at the beginning of LEBT. Further, the tomographic reconstruction method is compared with the solenoid scan method and the rms emittance values are found to be in good agreement. The measured tomographic phase space distribution has then been used as TraceWin input for LEHIPA end-end beam dynamics simulations and the LEHIPA beam line parameters are re-optimized for minimum beam emittance growth. This paper presents the simulations of CT technique, benchmarking simulations with TraceWin, phase space reconstruction with measured beam profiles and beam dynamics studies of LEHIPA using the reconstructed beam distributions.
Transition metal centers with anharmonic elastic interactions in one-dimensional spin-crossover solids
Authors: Metatla Abboud , Nicolazzi William , Latelli H’mida , Bousseksou Azzedine 
Published: July 2024

Abstract
An exact examination of a one-dimensional (1D) anharmonic elastic model describing the thermodynamic properties of spin-crossover (SCO) solids is presented. This elastic model incorporates both intra-chain and mean field inter-chain interactions, providing a more understanding of 1D SCO materials. Numerical findings for a linear chain of spins unveil intriguing features, such as a two-step-like transition. Extending the model to interacting chains leads to an additional term in the effective ligand field of the system’s Hamiltonian, thereby enhancing its predictive power by accounting for more elastic constants of interactions. This augmentation reinforces the model’s validity in capturing the spin-crossover phenomenon. Numerical results in this extended framework elucidate clearer two-step-like spin crossover transitions, with the HS_LS fraction of spins approaching maximum values at equilibrium temperature

Effect of graphite concentration on the electrochemical performance of a novel α-MnO2-expanded graphite-PVDF composite cathode material based on FTO substrate
Authors: Philip Abin , Ruban Kumar A 
Published: July 2024

Abstract
A facile chemical reduction method is employed for the synthesis of α-MnO2 followed by ultrasonication with synthetic graphite and poly (vinylidene pyrrolidone) PVDF for the development of α-MnO2-expanded graphite-PVDF (MGP) composite. Known masses of MGP composite are drop-casted on a fluorine-doped tin oxide (FTO) conducting glass substrate for the fabrication of composite electrodes to use as the cathode. The compositional effects of various weight percentages of graphite on the electrochemical performance of the MGP composite are studied. The increase in graphite’s weight percentage is always accompanied by an equal reduction in the weight of MnO2 by maintaining a constant amount of PVDF. We demonstrate a maximum electrochemical performance for the composite containing 80% MnO2, 10% expanded graphite, and 10% PVDF, further increases in graphite concentration (reduction in that of MnO2) have detrimental effects on the performance. The basis characterisation of the composite is carried out using XRD, FTIR, UV–vis, AFM, and SEM and the electrochemical studies are done using CV, GCD and EIS. We observe both faradaic and non-faradaic charge storage mechanisms in the composite samples with a 35% capacitive contribution and a 65% diffusive contribution to the total capacitance. Moreover, the composite electrode demonstrates a maximum specific capacitance of 358 F g−1 at 10 mV s−1 with an outstanding power density of 2.8 KW Kg−1.

Published: July 2024

Abstract
Potassium doped lanthanum manganese perovskite oxides, La1−xKxMnO3, with nanofibrous structure, are prepared and used for Photo-Fenton degradation of antibiotics, including ciprofloxacin (CIP), tetracycline (TC), and sulfathiazole (ST). Effects of K doping on the textural structure, optical property, band gap and surface chemistry of LaMnO3 are investigated, showing that La0.95K0.05MnO3 (LKMO-5) has the optimal properties. The photoelectric measurements, including photoluminescence (PL), photocurrent response (PCR) and electrochemical impedance spectroscopy (EIS), also suggest that the LKMO-5 has the best electron–hole separation efficiency, the most amounts of irradiated electrons and the lowest impedance. Photocatalytic tests indicate that LKMO-5 not only shows the best activity for CIP degradation, but also exhibits good stability in the reaction, with negligible activity loss within four cycles. Mechanism investigations, explored by the radical trapping experiments and with the reference of band positions, indicate that superoxide radical ions (·O2−) and holes (h+) are the major reactive species of the reaction.

We report the magnetic field dependent magnetization and magnetoresistance (MR) properties of La2/3Sr1/3MnO3 (LSMO)/

γ

-Fe2O3/LSMO trilayer heterostructure and single layer LSMO film grown on SiO2/Si (100) substrates utilizing Pulsed Laser Deposition technique. The metal- insulator-metal configuration is a magnetic tunnel junction topology, which is a parallel network of two metallic layers (LSMO) and one insulating layer (

γ

-Fe2O3) in current-in-plane (CIP) geometry. The intrinsically inhomogeneous polycrystalline trilayer film shows much lower (almost half ) coercivity, compared to single layer LSMO film. The MR-H [MR = (ρ (H)-ρ (0))/ρ (0)] behavior of the films is studied under two regimes namely, Low Field Magnetoresistance (LFMR) and High Field Magnetoresistance (HFMR) at 5 K and 300 K in the field range of 0–7 T. Several equations were developed to simulate the experimental MR-H data of the studied samples. For both the films, in the LFMR region (0 T < H ≤ 1 T @ 5 K), the variation in MR exhibits a linear increase with H, followed by a logarithmic behavior in the HFMR region (1 T < H ≤ 7 T @ 5 K). For the trilayer film in CIP geometry, a negative MR of 16% is achieved at 5 K and 1 T field conditions, while LSMO single layer shows a negative MR of 13% at same temperature and field conditions. The MR obtained at high field (7 T) for both the films is quantitatively equal with a value of 38% @ 5 K and 15% @ 300 K. We obtained significantly better MR-H results for the trilayer in current-perpendicular-to-plane (CPP) configuration, where the two metallic layers and an insulating layer are in series. In the CPP configuration, MR is 21% @ 5 K and 1 T field, while it reached to 44% at 5 K and 7 T field. At room temperature, the trilayer heterostructure shows MR of 17% at 7 T field condition. At a higher field of 9 T, trilayer film in CPP mode exhibits MR value of 48% @ 5 K and 23% @ 300 K. Further, the anti-parallel and parallel magnetization states of the MIM device are well manifested in CIP and CPP geometries.
One-loop power spectrum in ultra slow-roll inflation and implications for primordial black hole dark matter
Authors: Ballesteros Guillermo , Egea Jesús Gambín 
Published: July 2024

AbstractWe apply the in-in formalism to address the question of whether the size of the one-loop spectrum of curvature fluctuations in ultra-slow-roll inflation models designed for producing a large population of primordial black holes implies a breakdown of perturbation theory. We consider a simplified piece-wise description of inflation, in which the ultra-slow-roll phase is preceded and followed by slow-roll phases linked by transitional periods. We work in theδϕ-gauge, including all relevant cubic and quartic interactions and the necessary counterterms to renormalize the ultraviolet divergences, regularized by a cutoff. The ratio of the one-loop to the tree-level contributions to the spectrum of curvature perturbations is controlled by the duration of the ultra-slow-roll phase and of the transitions. Our results indicate that perturbation theory does not necessarily break in well-known models proposed to account for all the dark matter in the form of primordial black holes.
