Authors: Lobinger Dominik , Reiche Alicia , Hiebinger Andreas , Bodner Johannes 
Published: September 2023

Abstract
Background The so-called nonintubated or awake video-assisted thoracoscopic surgery (NIVATS) is performed on spontaneously breathing patients, which was shown to reduce postoperative complications and shorten hospital stay.
Case Description Awake uniportal VATS was indicated for the evacuation of an extensive, superinfected hemothorax with symptomatic mediastinal shift in a patient with advanced mediastinal SMARCA4-deficient tumor and declined condition, who did not allow a general anesthetic procedure and was not a candidate for extensive surgery.
Conclusion This short microinvasive intervention was a prerequisite to stabilize the threat to the patient's life and thus potentially enable any further tumor-specific therapy.
Laryngeal Imaging: Anatomy and Pathology
Authors: Solanki Rajendra , Prajapati Pooja 
Published: September 2023

AbstractImaging plays an important role in diagnostic evaluation of laryngeal lesions. The real value of imaging comes when there is a need to decide the feasibility of speech conservation therapy. Cross-sectional imaging allows excellent depiction of the intricate anatomy of the larynx and the characteristic patterns of tumor extension as well as the status of cervical nodal disease. Imaging studies also help in the post-therapeutic follow-up of patients with laryngeal cancers. In this article, we review the currently used laryngeal imaging techniques and protocols, the key anatomic structures relevant to tumor spread and the characteristic patterns of submucosal extension and invasion of laryngeal cancer. The role of CT and MRI in the evaluation of patients with laryngeal SCC and the impact of imaging findings, staging and surgical aspects is also discussed.

AbstractPelvic floor, a funnel-shaped muscular structure plays a significant role in bowel and bladder activities. Defecatory disorders result from the structural changes and functional disorders. Pelvic floor dysfunction affects 15% of multiparous women. It is being expected that after 30 years, there would be 45% rise in demand of pelvic floor imaging. After ruling out primary and secondary causes of constipation, diagnosis of obstructed defecation syndrome (ODS) is made. ODS is emerging as one of the important causes of constipation. As the symptoms are nonspecific and examination findings are frequently inaccurate, the clinical evaluation becomes a difficult task. Hence, various imaging modalities are becoming popular as an adjunct tool for the assessment of these disorders. Clinical management of ODS is based on the Constipation and Bowel Activity Score (CABA) and delineation of the pelvic floor anatomy. After defining the pelvic floor anatomy–based structural abnormality, day care ambulatory surgical procedure, that is, stapled transanal resection rectopexy (STARR), is offered to the patients of ODS. It provides significant relief to patients suffering from constipation and reduction in postoperative CABA score. This review discusses the role of magnetic resonance defecography imaging in ODS its impact on subsequent management.

Published: September 2023

Objective There is no recommendation in the literature on optimal positioning of the newborn immediately at birth during delayed cord clamping. To evaluate if prone positioning on the mother's chest at birth during delayed cord clamping leads to a higher hematocrit at 30 hours of life compared to supine positioning.
Study Design A randomized unblinded trial comparing prone and supine position of the newborn before umbilical cord clamping. Healthy newborns ≥36 weeks gestational age and born vaginally with cephalic presentation were included. The newborn was randomized to prone or supine position. Umbilical cord clamping was delayed in both groups to 1 minute after birth. The primary outcome was hematocrit at 30 hours of life. As a secondary outcome, cerebral tissue oxygenation (CrSO2) values were compared between both groups by near infrared spectroscopy.
Results There was no difference in hematocrit at 30 hours of life between supine and prone positions with a mean at 52 and 53.1, respectively, mean difference −1.1 (95% confidence interval:−2.7, 0.5), p = 0.17. Newborns in supine and prone positions had comparable level of CrSO2 at 30 hours of life with a mean at 84.1 and 82.2, respectively, mean difference 1.9 (−0.2, 4.0), p = 0.07. There was no correlation between hematocrit and CrSO2 at 30 hours of life (r = 0.14).
Conclusion There was no difference between prone and supine positioning immediately after birth during delayed cord clamping on hematocrit at 30 hours of life. In the absence of clear findings, further studies with assessment of the effect of position on breastfeeding success in the case room, on maternal satisfaction and outcome beyond 30 hours are needed to make adequate recommendations on positioning.

The imitation game: indirect European Union influence on municipal officials’ attitudes towards elite corruption and informal payments
Authors: Sircar Indraneel 
Published: September 2023

AbstractThe European Union has sought to democratise its post-communist neighbours for the past three decades, starting with Central and Eastern Europe after 1989. Since the end of the wars in Former Yugoslavia in 2000, the EU first pursued closer integration with the Western Balkans followed by the goal of enlargement. However, despite intensive EU involvement, the fight against corruption has stagnated or deteriorated in post-communist Europe, particularly in Former Yugoslavia. The central question in the article is whether indirect EU influence has led municipal officials—who are at the front line of vital distributive decision-making for citizens at the local level—to imitate (or emulate) attitudes related to corruption and to informality in line with EU norms. The article focuses on the case of Serbia, where anti-corruption progress has been particularly slow. Using a survey of Serbian municipal officials, the article examines whether indirect EU influence via involvement in policy implementation affected attitudes towards informal payments, and through a vignette-based survey experiment, whether those involved in EU-compliant policy implementation are less accepting of local political elite corruption.
Risk identification approaches and the number of risks identified: the use of work breakdown structure and business process
Authors: Kountur Ronny , Sari Martdian Ratna 
Published: September 2023

AbstractLosses and damages that any company or organization experience is usually caused by some unidentified risks that hit them unprepared. Some companies even must close their business or discontinue their operation due to the huge negative impact of the risk that hit them. Knowing the risks that an organization face is important. Risk needs to be identified properly. Though there had been some approaches a person can use in identifying risk, most of those approaches are complex, require several people involved, are too subjective, and are not able to identify unseen risks. Therefore, the purpose of this study is to know which risk identification method can identify more risks when knowledge of the context is controlled. The study made use of experimental research design with the use of covariance analysis in analyzing the data. With a 95% level of confidence, it was found that risk identification methods affect the number of risks identified. The business process approach seems to identify more risks than the work breakdown structure approach and placebo. The step-by-step procedures in doing the business process approach and work breakdown structure approach are also introduced in this study.
“You are fake news”

Published: September 2023

Abstract
Using the methodology of conversation analysis and a modified analytical framework, this article attempts to
characterize and investigate Trump’s practices to resist the agendas of the interviewers’ questions during the press briefings
held by the Trump Administration in 2020. Statistical data show that Trump mainly used four types of overt resistant response
practices in order of decreasing frequency: (1) Justifying the resistance; (2) Providing a partial answer; (3) Flatly
refusing to answer without any explanation; and (4) Resorting to a personal attack, which is a new type of overt resistant
practices. However, only one type of covert resistant response practice is identified, i.e. Repeating words subversively. The
potential reasons for Trump’s use of such practices are discussed. In essence, Trump’s deliberate use of resistant response
practices is a typical reflection of the right-wing populist politicians’ claim of “authenticity” rather than “truth” in the
Post-Truth era.
Bragg grating based entangled biphoton dispersion management
Authors: Armaghani Sahar , Rostami Ali , Mirtagioglu Hamit 
Published: September 2023

Abstract
In the realm of quantum information processing and precision measurements, a range of non-classical effects based on entangled photon pairs are employed. Non-local dispersion cancellation is one of these properties, in which the second photon (idler) can be manipulated to cancel the effects of dispersion on the first photon (signal). In the present study, a thorough investigation is conducted into non-local dispersion cancellation by using excitation modes within a Bragg grating slab waveguide. We present a complete theoretical analysis of non-local dispersion cancellation for frequency-limited entangled photon pairs. For the analysis of the effect of dispersion cancellation, we use a spontaneous parametric down-conversion (SPDC) photon pair source with frequency correlation and anti-correlation as the entangled source. To evaluate the dispersion cancellation effect for information processing applications, the second correlation function is used and calculated as a practical and tangible metric. Considering different cases for Bragg Grating waveguide the results on both photons are extracted and discussed. Moreover, we will show that the physical parameters of the waveguide that the second photon is propagated inside will be effective in minimizing the width of the temporal correlation function. Hence, this study underscores the feasibility of achieving non-local dispersion cancellation through strategic optimization of optical and geometric parameters in the Bragg Grating waveguide, with potential implications for quantum information processing and high-resolution sensing endeavors.

Abstract
We investigate the possible anisotropy of the universe using data on the most up-to-date type Ia supernovae, i.e., the Pantheon+ compilation. We fit the full Pantheon+ data with the dipole-modulated ΛCDM model and find that the data are well consistent with a null dipole. We further divide the full sample into several subsamples with different high-redshift cutoffs

confidence level only if

Asymptotic analysis of the angular motion of a projectile based on Lyapunov artificial-small-parameter perturbation
Authors: Wang Chen , Ding Libo 
Published: September 2023

Abstract
In the traditional analysis of the angular motion of a projectile, the coefficient freezing method is often used to simplify the differential equation of angular motion. However, this method gives a poor approximation for long time scales. In this paper, based on Lyapunov artificial-small-parameter perturbation theory, an asymptotic analytical solution for the angular motion of a projectile is derived by constructing artificial small parameters for the variable coefficient terms in the original equation. In an example, the angular motion of a single-channel rotating projectile with two-dimensional trajectory correction was analyzed. The method proposed in this paper was compared with the coefficient freezing method. The results show that the proposed method can give a good approximation over a long time scale. This study may be significant for the solution of differential equations with variable coefficients and may be useful for certain engineering applications.

Authors: Chen Xiangzhi , Tang Lihua , Zhong Yuansheng 
Published: September 2023

Abstract
Collision safety of mobile robot is one of the important indexes of robot safety evaluation. The acceleration signal of the robot can completely feed-back the state of the collision process, but it is also vulnerable to noise interference such as vibration and impact, which is difficult to be used for direct analysis. In order to solve the problem of mixing acceleration signal with impact noise and periodic vibration noise during robot collision, a combined filtering noise reduction method based on empirical mode decomposition (EMD), improved wavelet threshold method and dynamic sliding window is proposed. And a wavelet adaptive threshold function is constructed. The wavelet coefficients are automatically adjusted using the information of decomposition degree and noise level, and a dynamic adjustment strategy of sliding window length is designed. The acceleration information of robot can be effectively extracted in the process of strong noise collision. The experimental results show that this method has better noise reduction effect than other methods.
Research on low speed control position observer for accumulator electric locomotive PMSM
Authors: Zhu Longji , Shao Hua , Wang Xiaohu 
Published: September 2023

Abstract
The PMSM of accumulator electric locomotive is generally controlled without position sensor, but the traditional position observer has the low speed observation accuracy, and the nonlinear factors of many mechanical parameters, such as torque feedback and moment of inertia, interfere with the low dynamic performance of the motor control system. A position observation model based on the nonlinear expansion observer is designed. The position observation model is constructed by using the relationship among the speed of the motor, the position angle of the rotor and its angular acceleration as well as the nonlinear function. Because it can avoid measuring the load torque and using the nonlinear expansion observer to estimate the uncertain disturbance, it is easy to realize. The simulation results show that the position observer can make the electric locomotive run stably under low speed control and has good low speed dynamic performance.
Model prediction controller for penetration mechanism of seabed cone penetration test system
Authors: Wang Shimin , Ren Ziqiang , Zhou Hang , Chen Jiawang 
Published: September 2023

Abstract
The system of seabed Cone Penetration Test (CPT) is a kind of equipment for offshore investigations. Seabed CPT is used to assess multiple physical properties of marine sediments. Constant-rate penetration mechanism is the core part of seabed CPT, which adopts dual-cylinder drive to penetrate the probe rod into the seafloor sediments at a constant speed (2cm/s). At present, the domestic CPT and its penetration equipment almost all rely on imports. In the process of system design, we found that the traditional PID control of the hydraulic cylinder position control accuracy is low, so we need to study higher precision position tracking control method to achieve uniform penetration of the probe rod. In this paper, a Linear Time-Varying Model Predictive Controller (LTV-MPC) is introduced, which can control two hydraulic cylinders to penetrate probe rod into the seabed sediment with smaller penetration rate error under the condition of changing penetration resistance.
Lithium-ion battery state-of-charge estimation based on long-short-term memory neural network and square-root cubature Kalman filter

Published: September 2023

Abstract
Due to the widespread use of Li-ion batteries in electric vehicles, battery management systems for monitoring the status and ensuring the safe operation of Li-ion batteries have been extensively studied. Online monitoring of the state of charge (SOC) is crucial for lithium-ion batteries, but achieving precise SOC estimation is a difficult task due to battery dynamics and the influence of factors such as current, temperature, and operating conditions on SOC variability. This paper introduces a novel approach that combines a Long Short-Term Memory (LSTM) network with a square-root cubature Kalman filter (SRCKF) to address this challenge. To tackle the issue at hand, the proposed methodology employs a two-step approach. Initially, the LSTM network is utilized to capture the complex relationship between the state of charge (SOC) and the measured variables, including current, voltage, and temperature. Subsequently, the output of the LSTM network is subjected to smoothing using the SRCKF technique, leading to precise and consistent SOC estimation. A notable advantage of this method is its ability to simplify the arduous task of parameter tuning for the LSTM network, eliminating the need for constructing a battery model. The experimental results demonstrate that the maximum error in estimating the state of charge (SOC) using this particular method is constrained within the 5% threshold. Compared with using a separate LSTM method at different temperatures, by using the combination method, the root mean square error and maximum error of SOC estimation are greatly reduced.

Abstract
Arrester is used to protect various electrical equipment in the power system from lightning overvoltage, working overvoltage, power frequency transient overvoltage impact and damage. Zinc oxide arrester is widely used in power system. Creepage distance is a necessary item of arrester performance test. It is a necessary project for lightning arrester factory testing and centralized network access testing. At present, the measurement of arrester creepage distance mainly adopts the artificial method of paper tape measurement or wire measurement. In this paper, a measurement system for arrester creepage distance is developed by using three-dimensional reconstruction and laser vision detection, which realizes one-click and fully automatic detection of creepage distance. The field application results show that the system not only solves the problems of heavy workload and low measurement accuracy of manual measurement methods, but also displays the measurement results in real time, which significantly improves the reliability and flexibility of measurement work, shortens the measurement time and improves the work efficiency.
Research on the overvoltage suppression strategy of single-phase photovoltaic grid-connected systems based on FCS-MPDPC
Authors: Yang Aimin , Yang Jianfeng , Li Ting 
Published: September 2023

Abstract
For the overvoltage problem brought by the access of high-penetration photovoltaic power plants to the low-voltage distribution network, this paper chooses to deal with it by using the reactive power regulation capability of photovoltaic power plant inverters, which reduces the equipment investment in distribution line voltage regulation. Based on the reactive power regulation theory of the inverter, a finite set model predictive direct power control method is proposed by constructing a virtual voltage vector, taking a single-phase cascaded 2H bridge grid-connected inverter as an example, to realize independent control of active and reactive power. By setting different power reference values, the inverter can be made to have two functions: grid-connected per-unit power factor and reactive power control during overvoltage. Finally, the two modes of inverter operation are verified by Simulink simulation, and the verification by example shows that the method can limit the grid-connected voltage deviation to within 7% and meet the requirements of grid-connected regulations.
