Published: April 2023

AbstractRecent scholarship suggests that groups who oppose acting on climate change have shifted their emphasis from attacking the credibility of climate science itself to questioning the policies intended to address it, a position often called ‘response skepticism’. As television is the platform most used by audiences around the world to receive climate information, we examine 30 news programmes on 20 channels in Australia, Brazil, Sweden, the UK and USA which included coverage of the 2021 report by the Intergovernmental Panel on Climate Change (IPCC) on the Physical Science. Using manual quantitative content analysis, we find that skepticism about the science of climate change is still prevalent in channels that we have classified as ‘right-wing’, but largely absent from channels classified as ‘mainstream’. Forms of response skepticism are particularly common in ‘right-wing’ channels, but also present in some ‘mainstream’ coverage. Two of the most prominent discourses question the perceived economic costs of taking action and the personal sacrifices involved. We explore the implications of our findings for future research and climate communication.

Generative UAP attacks against deep‐learning based modulation classification
Authors: Li Xiong , Rao Wengui , Chen Shaoping 
Published: April 2023

AbstractThanks for its powerful feature extraction capability and unprecedented success in computer vision and language processing tasks, deep learning (DL) has also been applied in recent years to wireless communications. However, DL models are proved to be inherently vulnerable to adversarial perturbations: carefully crafted perturbations that appear imperceptible but can fool the models to induce misclassification. Existing researches in wireless communications employ the gradient‐based or optimization based methods, for example, FGSM, PGD and iterative FGSM, to craft input‐dependent adversarial perturbations. However, these methods have a high computational complexity and the perturbations they craft cannot be readily applied to fool DL‐based algorithms in wireless communications. In this paper, the efficient generation of universal (input‐agnostic) adversarial perturbations (UAPs) used to attack DL‐based modulation classification algorithms is studied. Communication signals exhibit unique characteristics, for example, received modulated signals after transmitting through noisy channels are densely distributed around the modulation constellation points. In this work, the authors have proposed, by making use of this unique characteristics, a generative network to model the distribution of adversarial perturbations for high‐efficiency generation of UAPs, which can fool the DL‐based modulation classification algorithms for most inputs. Instead of attacking all regions of modulated signals, attention mechanisms are introduced in generative network design that enables the perturbations to be concentrated around the constellation points. In this way, a higher attack efficiency and a lower perceptibility are achieved by crafting UAPs with smooth variations and more focused attack. In addition, a diversity term is included in loss function to help capture a wide range distribution of adversary perturbations that will help the generation of more diverse adversary perturbations. Once trained, the generative network can construct with ease a large number of UAPs with some favorable features, which will benefit more efficient adversarial attack and faster adversarial training. Experimental results show the superiority of our proposed method in terms of attack efficiency, imperceptibility and diversity over existing methods.

AbstractThis paper studies the tracking control problem for a climate chamber control system used for determining volatile organic compounds. A new nonlinear controller, for the first time, is designed for the temperature and humidity control of a climate chamber. For one thing, based on the backstepping technology, an improved control method is proposed with the help of the implicit function theorem instead of employing system linearization. In this way, simplification of the controlled system can be avoidable so that the control accuracy is promoted. For another, without approximations by fuzzy logics or neural networks, the number of complex computations are reduced a lot so that the control rate is improved considerably. In the end, simulation is conducted by Matlab to validate the effectiveness and superiority of the proposed control method.
Personalized federated learning on NLOS acoustic signal classification
Authors: Wang Hucheng , Qiu Suo , Wang Jingjing , Zhang Lei , Wang Zhi , Luo Xiaonan 
Published: April 2023

AbstractTo identify non‐line‐of‐sight, acoustics‐based indoor positioning needs to collect audio recordings of sound fields in multiple rooms and upload them to the central server for training. However, if the transmission process or the server‐side suffers from malicious attacks, private data may be leaked. To address both training difficulties and privacy issues simultaneously, a novel model for personalized federated learning is proposed. This model incorporates user frequency and room data capacity while also taking into account significant differences in positioning data and room layout. The proposed model can accurately identify differences between various room data during aggregation on the server‐side. By collecting data in actual indoor environments and comparing it with existing algorithms, the proposed method achieved 90% accuracy in verifying data for unfamiliar rooms.
An LCC‐S compensated wireless power transfer system using receiver‐side switched‐controlled capacitor combined semi‐active rectifier for constant voltage charging with misalignment tolerance
Authors: Wang Wenbo , Deng Junjun , Chen Deliang 
Published: April 2023

AbstractThe output characteristics of wireless power transfer systems are strongly susceptible to coupling and load variations. To achieve a constant voltage output under varying coupling and load, a voltage regulation method based on a combination of a semi‐active rectifier (SAR) and a switched‐controlled capacitor (SCC) is proposed for the LCC‐S topology. Adjusting the SAR can effectively regulate the voltage, and the introduction of SCC compensates the impedance brought by SAR, ensuring that the resonance condition is fully satisfied at the receiver side. Thus, the proposed wireless power transfer system can achieve zero phase angle over the entire load and coupling range, minimizing reactive power losses. This control method only needs to collect the signal from the receiver side, which enables single‐side control as well as avoids the wireless communication. The situation of coupler parameter drift due to misalignment is also considered. Even if the self‐inductance changes, the zero phase angle can be guaranteed on the receiving side by adjusting the SCC, and the zero voltage switching of the transmitter side can still be achieved. The principle prototype of 3 kW is constructed and the experimental results prove the effectiveness of the proposed method.
Exploring the internal rotation of the extremely low-mass He-core white dwarf GD 278 with TESS asteroseismology

Published: April 2023

Context. The advent of high-quality space-based photometry, brought about by missions such as Kepler/K2 and TESS, makes it possible to unveil the fundamental parameters and properties of the interiors of white dwarf stars, particularly extremely low-mass white dwarfs, using the tools of asteroseismology.
Aims. We present an exploration of the internal rotation of GD 278, the first known pulsating extremely low-mass white dwarf to show rotational splittings within its periodogram.
Methods. We assessed the theoretical frequency splittings expected for different rotation profiles and compared them to the observed frequency splittings of GD 278. To this aim, we employed an asteroseismological model representative of the pulsations of this star, obtained by using the LPCODE stellar evolution code and the LP-PUL non-radial pulsation code. We also derived a rotation profile that results from detailed evolutionary calculations carried out with the MESA stellar evolution code and used it to infer the expected theoretical frequency splittings.
Results. We find that the best-fitting solution when assuming linear profiles for the rotation of GD 278 leads to angular velocity values at the surface and center that are only slightly differential, and still compatible with rigid rotation. Additionally, the values of the angular velocity at the surface and the center for the simple linear rotation profiles and for the rotation profile derived from evolutionary calculations are in very good agreement. Also, the resulting theoretical frequency splittings are compatible with the observed frequency splittings, in general, for both cases.
Conclusions. The results obtained from the different approaches followed in this work to derive the internal rotation of GD 278 agree. The fact that they were obtained by employing two independent stellar evolution codes gives our results robustness. Our results suggest only a marginally differential behavior for the internal rotation in GD 278 and, considering the uncertainties involved, this is very compatible with the rigid case, as has been observed previously for white dwarfs and pre-white dwarfs. The rotation periods derived for this star are also in line with the values determined asteroseismologically for white dwarfs and pre-white dwarfs in general.

Johannes Müller (1801–1858) und seine Schule – Wegbereiter und Gigant der deutschen Physiologie
Authors: Koehler Ulrich 
Published: April 2023

ZusammenfassungUm die Mitte des 19. Jahrhunderts war Johannes Müller der unbestritten vielseitigste und genialste Physiologe seines Zeitalters. Müller wurde im Jahre 1801 als ältestes von 5 Kindern in Koblenz geboren. Er erhielt eine hervorragende Ausbildung in Mathematik und den alten Sprachen und konnte so die Schriften von Aristoteles im Original mühelos lesen.Nach dem Abitur 1818 diente er ein Jahr bei den Pionieren, 1819 immatrikulierte er sich an der Universität in Bonn. 1821 erhielt er, noch als Student, den Universitätspreis für seine wissenschaftliche Arbeit über die Atmung des Fötus. Müller wurde 1822 in Bonn promoviert und ging anschließend nach Berlin, wo er Vorlesungen des Anatomen Karl Asmund Rudolphi gehört hat.1824 habilitierte er sich in Bonn für Physiologie und vergleichende Anatomie. Nach seinen Bonner Jahren folgte er 1833 dem Ruf an die Berliner Universität auf den Lehrstuhl von Rudolphi. In Berlin erschien sein berühmtes „Handbuch der Physiologie“ (1833–1840). Müllers Arbeitsgebiet betraf die Physiologie, die Humananatomie sowie die vergleichende zoologische Anatomie und pathologische Anatomie.Müller hat eine Vielzahl an Publikationen und Schriften hinterlassen. Er und seine zahlreichen Schüler (Emil du Bois-Reymond, Ernst Haeckel, Hermann von Helmholtz, Friedrich Gustav Jakob Henle, Carl Ludwig, Theodor Schwann und Rudolf Virchow etc.) begründeten den Weltruhm des Berliner Physiologischen Instituts. Die Anfang des 19. Jahrhunderts vorherrschende naturphilosophisch ausgerichtete Denkweise der Medizin wurde durch Müller mehr und mehr durch eine naturwissenschaftlich orientierte ersetzt.

Published: April 2023

AbstractThoracotomy is defined as an incision made by the surgeon in the chest wall in order to allow visibility of the thoracic cavity content. This can be used by surgeons to treat thoracic cavity content diseases including the heart, lungs, esophagus, and other organs. Thoracic incision closure remains an item with no consensus. Therefore, we present an easy way and give a little tip for closure using the slipknot that will allow the correct approach of ribs and the successful closure of the intercostal space.

Birth Brachial Plexus Palsy: An Indian Perspective
Authors: Thatte Mukund R. , Shah Harsh R. , Hiremath Amita 
Published: April 2023

AbstractBirth brachial plexus palsy (BBPP) is an unfortunate outcome of a difficult labor, which can often lead to long-lasting upper limb impairments. Spontaneous recovery may or may not occur. Timely diagnosis of the condition and initiation of the appropriate treatment can be instrumental in decreasing the functional impact. The management begins right from the day the child presents first and ranges from physiotherapy to surgical intervention such as nerve repair/transfer or grafts. The sequelae of the condition are also quite common and need to be detected preemptively with initiation of appropriate treatment. However, prevention is the key to reducing the incidence of secondary deformities. In this study, the team of authors, based on their considerable experience, discuss their approach to the management of BBPP. This is done in the background of Indian cultural practices and social constraints. A detailed discussion has been done on importance of preoperative passive joint mobilization regime and role of botulinum toxin in the authors' preferred ways of surgical correction of primary as well as secondary deformities. An extensive review of peer-reviewed publications has been done in this study, including clinical papers, review articles, and systematic review of the subject. Good results are possible with early and appropriate intervention even in severe cases.
Work-Related Sleep Disorders: Causes and Impacts
Authors: Gusman Elen , Standlee Jordan , Reid Kathryn J. , Wolfe Lisa F. 
Published: April 2023

AbstractInsufficient sleep syndrome, shift work disorder, and obstructive sleep apnea (OSA) not only significantly impact the health of affected individuals, but also pose a threat to public safety. This article describes the clinical manifestations and impact of these sleep disorders, particularly as they pertain to workers' health and those with safety-sensitive positions. Sleep deprivation, circadian rhythm disruptions, and excessive daytime sleepiness—hallmarks of insufficient sleep, shift work disorder, and OSA, respectively—all lead to a series of cognitive deficits and impaired concentration that affect workers in a wide variety of fields. We describe the health consequences of these disorders along with treatment strategies, with a focus on current regulatory standards and the under-recognition of OSA in commercial drivers. Given its large scale, there is a need for improved guidelines and regulations for the screening, diagnosis, treatment, and long-term follow-up of OSA in commercial motor vehicle drivers. Increased recognition of the ways in which these sleep disorders impact workers will pave the way for significant improvements in occupational health and safety.
The Impact of Respiratory Therapist Performed Point-of-Care Lung Ultrasound on the Respiratory Care in Neonates, Manitoba Experience, Canada
Authors: Elsayed Yasser , Sheldon Josh , Gigolyk Shere 
Published: April 2023

Abstract
Objective We aimed to evaluate the impact of the registered respiratory therapist (RRT) performed point-of-care lung ultrasound (POC-LUS) on patient management in the neonatal intensive care unit (NICU).
Study Design This is a retrospective cohort study of neonates who had RRT performed POC-LUS in two level III NICUs in Winnipeg, Manitoba, Canada. The analysis aims mainly to describe the implementation process of the POC-LUS program. The primary outcome was the prediction of the change in clinical management.
Results A total of 136 neonates underwent 171 POC-LUS studies during the study period. POC-LUS resulted in a change in clinical management following 113 POC-LUS studies (66%), while it supported continuing the same management in 58 studies (34%). The lung ultrasound severity score (LUSsc) was significantly higher in the group with worsening hypoxemic respiratory failure and on respiratory support than infants on respiratory support and stable or not on respiratory support, p < 0.0001. LUSsc was significantly higher in infants on either noninvasive or invasive than those not on respiratory support, p-value <0.0001.
Conclusion RRT performed POC-LUS service utilization in Manitoba improved and guided the clinical management of a significant proportion of patients who received the service.

Published: April 2023

Objective Monitoring heart rate (HR) and oxygen saturation (SpO2) in infants is essential in the neonatal intensive care unit. Wireless pulse oximeter technology has been advancing but with limited accuracy data on preterm infants. This observational study compared HR and SpO2 of the wireless Owlet Smart Sock 3 (OSS3) to the wired Masimo SET (Masimo) pulse oximeter in preterm or <2.5 kg infants.
Study Design Twenty-eight eligible infants were enrolled. They weighed between 1.7 and 2.5 kg and were without anomalies or medical instability. OSS3 and Masimo simultaneously monitored HR and SpO2 for 60 minutes. The data were aligned by time epoch and filtered for poor tracings. The agreement was compared using the Pearson's correlation coefficient, the Bland–Altman method, average root mean square (ARMS), and prevalence and bias adjusted kappa (PABAK) analyses.
Results Two infants' data were excluded due to motion artifacts or device failures. The corrected gestational age and current weights were 35 ± 3 weeks and 2.0 ± 0.2 kg (mean ± standard deviation), respectively. Over 21 hours of data showed that HR was strongly correlated between the two devices (r = 0.98, p < 0.001), with a difference of −1.3 beats per minute (bpm) and the limit of agreement (LOA) −6.3 to 3.4 bpm based on the Bland–Altman method. SpO2 was positively correlated between the two devices (r = 0.71, p < 0.001) with a SpO2 bias of 0.3% (LOA: −4.6 to 4.5%). The estimated ARMS of OSS3 compared with Masimo was 2.3% for SpO2 in the 70 to 100% range. The precision decreased with lower SpO2. A strong agreement (PABAK = 0.94) was between the two devices on whether SpO2 was above or below 90%.
Conclusion OSS3 provided comparable HR and SpO2 accuracy to Masimo in preterm or <2.5 kg infants. Motion artifacts, lack of arterial blood gas comparisons, and lack of racial and ethnic diversity are the study limitations. More OSS3 data on the Lower HR and SpO2 ranges were needed before implementing inpatient use.
