AbstractPreserved ratio impaired spirometry (PRISm) is defined by reduced FEV1 with a preserved FEV1/FVC ratio; some individuals with PRISm can also have restrictive ventilatory abnormality. The aim of this study was to clarify clinical features of restrictive and non-restrictive PRISm. In total, 11,246 participants (mean, 49.1 years; range, 35–65 years) from five healthcare centres were included in this study. We evaluated baseline characteristics of participants with restrictive PRISm (FEV1/FVC ≥ 0.7, FEV1 < 80% and FVC < 80%) and non-restrictive PRISm (FEV1/FVC ≥ 0.7, FEV1 < 80% and FVC ≥ 80%), and airflow obstruction (FEV1/FVC < 0.7). We examined the longitudinal risk of developing airflow obstruction by comparing spirometry results at baseline and 5 years post-baseline among 2141 participants. Multivariate analysis demonstrated that a history of asthma or smoking could constitute an independent risk factor for non-restrictive PRISm, and that non-restrictive PRISm was independently associated with the risk of developing airflow obstruction. In contrast, female sex, advanced age, and high BMI, but not history of asthma or smoking, were risk factors for restrictive PRISm. Restrictive PRISm was not associated with the development of airflow obstruction. In conclusion, our results indicate that PRISm can be categorized according to the presence or absence of restrictive abnormality. Non-restrictive PRISm, which does not meet the conventional criteria of obstructive and restrictive ventilatory abnormalities, may be a precursor of chronic obstructive pulmonary disease and merits increased monitoring.

Published: February 2023

AbstractWe revisited the effectiveness of state and entanglement transmission through a spin-chain-based quantum channel while altering the system parameters and the channel’s initial state. Our research is focused on the spin-1/2 XX chain with Dzyaloshinskii–Moriya (DM) interaction and the aim is to measure entanglement dynamics between different part of the chain. The speed of entanglement propagation is utilized to probe the evolution of the system via three scenarios: (i) pure Heisenberg interaction, (ii) pure DM interaction, and (iii) collaboration of both types of couplings. To accomplish this, we employ the fermionization approach to obtain an exact solution to the problem. Aside from investigating the influence of magnetic interaction type on entanglement transfer, the effect of selecting the initial state has also been studied. As a result, we discovered that the phase factor regulating the system’s initial state induces sharp drops in the propagation speed of entanglement. We also showed how to predict the location of these dramatic drops using the language of wave interference. In addition, the fastest transmission occurs at a special value of the phase factor in which the highest amount of entanglement reaches the system’s different pairs. On the other hand, we observe a continuous and flat range of this factor in which the least amount of entanglement is transmitted and for them we have a sharp drop in the speed profile.

AbstractTo recycle regenerative braking energy (RBE) while reducing demand charge in electrified railway, a co‐phase power supply system with hybrid energy storage system (HESS) is implemented. However, the dynamical degradation characteristic of battery is necessary to be considered in optimal operation of HESS. A bi‐level model considering battery degradation is proposed to obtain optimal sizing and operation of HESS. The proposed model includes a novel real‐time energy management strategy (EMS) using average power as thresholds, to effectively reduce the demand charge and energy consumption charge. Thresholds are dynamically adjusted with the consideration of battery capacity degradation. A real measured load profile from Beijing‐Shanghai high speed railway is studied. The results demonstrate that the proposed EMS performs better than previous EMS in cost saving. The dynamically adjusted thresholds of EMS are proved to be essential under the consideration of battery degradation. With the optimal sizing of the HESS, the traction substation can achieve 8.69% annual saving of demand charge and recycle 52.33% of the RBE. The results also show that a traction substation equipped with the HESS yields higher economic benefit than the energy storage systems equipped with only a battery or a supercapacitor.

AbstractAiming at the shortcomings of the current Canny edge detection method in terms of noise removal, threshold setting, and edge recognition, this paper proposes a method for improving Canny edge detection by geo‐information mapping. The shortcomings of the traditional Canny edge detection method are analyzed by using the Canny optimal criterion and Tobler's First Law, which points out the direction of edge detection optimization by using the difference between edge properties and noise properties. The property characteristics and spatial distribution rules of edge points and edge lines are inspected using the geographic information mapping theory and technical methods, and edge identification criteria are defined at two levels of edge points and edge lines. Finally, the method model of improved Canny edge detection is constructed by combining guided filtering. The experimental results show that the improved edge detection method has the advantages of enriched edge details, accurate edge recognition, and strong self‐adaptive capability. This is a new attempt of geo‐information mapping theory and technical method in image edge detection, which has certain theoretical significance and strong practical guidance.
Maps of secular resonances in the NEO region
Authors: Fenucci Marco , Gronchi Giovanni F. , Novaković Bojan 
Published: February 2023

Context. From numerical simulations, it is known that some secular resonances may affect the motion of near-Earth objects (NEOs). However, the specific location of the secular resonance inside the NEO region is not fully known because the methods previously used to predict their location cannot be applied to highly eccentric orbits or the time when the NEOs cross the orbits of the planets.
Aims. In this paper, we aim to map the secular resonances with the planets from Venus to Saturn in the NEO region, while including high eccentricity values as well.
Methods. We used an averaged semi-analytical model that can deal with orbit-crossing singularities for the computation of the secular dynamics of NEOs, from which we were able to obtain suitable proper elements and proper frequencies. Then, we computed the proper frequencies over a uniform grid in the proper elements space. Secular resonances can thus be located by the level curves corresponding to the proper frequencies of the planets.
Results. We determined the location of the secular resonances with the planets from Venus to Saturn, showing that they appear well within the NEO region. By using full numerical N-body simulations, we also showed that the location predicted by our method is fairly accurate. Finally, we provided some indications about possible dynamical paths inside the NEO region due to the presence of secular resonances.
Arpenter le milieu pour faire paysage L’émotion esthétique dans l’avènement de l’image dans la clinique de l’exclusion
Authors: Humphreys Derek , Lamadrid Martin 
Published: February 2023

Le paysage, production imaginaire bien cadrée, est une métaphore utile de l’interprétation en psychanalyse qui permet de situer le travail sur la représentation et ses transformations. Dans le champ de l’exclusion, où le rapport entre le réel et sa représentation est toujours instable, un travail qui précède l’organisation imaginaire du paysage est nécessaire pour accéder à la relation thérapeutique. C’est à partir de la démarche de Deligny que nous proposons une approche clinique dans le champ de l’exclusion : établissant des repères cartographiques référés à la contingence des mouvements des individus. Ces repères organisent la relation de l’individu à son territoire en deçà du registre représentationnel et nous permettent de suivre les émotions esthétiques susceptibles de faire advenir une représentation. Cette découverte de réalités nouvelles issues de la contingence permet d’échapper à une relation immuable à l’environnement. Ce travail sur l’image, dans lequel on crée des repères du quotidien pour que des objets puissent prendre forme afin d’accéder à un paysage, a un effet ré-humanisant dans ces conditions extrêmes, si l’on accepte que ce qui constitue la spécificité de l’Humain est sa capacité de rêver, de construire un monde à partir d’une l’illusion.
Schlaf und Schlafstörungen aus chronobiologischer Sicht
Authors: Schmidt Robert 
Published: February 2023

ZusammenfassungErholsamer Nachtschlaf ist die Grundvoraussetzung für das seelische und körperliche Wohlbefinden. Der Mensch verbringt ein Drittel seines Lebens schlafend. Der Schlaf ist eine ausgeprägte Ruhephase mit kaum vorhandener motorischer Aktivität und sehr geringer Reaktionsbereitschaft auf äußere Reize. Er dient der Erholung und dem Energiesparen – der Energieverbrauch sinkt im Schlaf um 10 %. Unser Gehirn speichert im Schlaf Gelerntes dauerhaft ab, unwichtige Informationen werden gelöscht. Unser modernes Leben führt jedoch oft dazu, dass unser Schlaf und das Schlafbedürfnis beeinträchtigt werden. Chronische Schlafstörungen wiederum haben erhebliche negative Einflüsse auf unsere Gesundheit. Um diesen vorzubeugen oder sie zu therapieren, benötigt es die Konzentration auf die richtige Schlafhygiene im Einklang mit dem individuellen Chronotyp und der Chronobiologie.
Direct Oral Anticoagulants: Laboratory Challenges and Antidotes
Authors: Beyer-Westendorf Jan , Köhler Christina 
Published: February 2023

AbstractThe use of direct oral anticoagulants (DOACs) is increasing in patients needing treatment of venous thromboembolism (VTE) and stroke prevention in atrial fibrillation (SPAF). This is due to the net clinical benefit in comparison to vitamin K antagonists (VKAs). The rise in DOAC use is accompanied by a remarkable reduction in heparin and VKA prescriptions. However, this rapid change in anticoagulation patterns brought new challenges to patients, prescribers, laboratories, and emergency physicians. Patients have new liberties concerning nutritional habits and comedication and no longer need frequent monitoring or dose adjustments. Still, they have to comprehend that DOACs are potent anticoagulants that may cause or contribute to bleeding. Challenges for the prescriber include decision pathways for choosing the right anticoagulant and dosage for a specific patient and to change bridging practice in case of invasive procedures. Laboratory personnel are challenged by DOAC due to limited 24/7 availability of specific DOAC quantification tests and by the impact of DOAC on routine coagulation assays and thrombophilia tests. Challenges for the emergency physician result from the increasing age of DOAC anticoagulated patients, the difficulties to establish last intake of DOAC type and dosage, to interpret coagulation test results in emergency situations, and to make decisions for or against DOAC reversal strategies in acute bleeding or urgent surgery. In conclusion, although DOACs make long-term anticoagulation safer and more convenient for patients, DOACs pose challenge to all healthcare providers involved in anticoagulation decisions. The key to correct patient management and optimal outcome therefore lies in education.
Schlafstörungen in der TCM
Authors: Simon Alexander 
Published: February 2023

ZusammenfassungDie TCM ist ein eigenständiges, vorwiegend auf klinischer Erfahrung basiertes Medizinsystem, das bei der Behandlung funktioneller Erkrankungen zunehmende Bedeutung erlangt. Aus Sicht der Chinesischen Medizin liegt die Hauptursache von Schlafstörungen in der fehlgeschlagenen „Absenkung“ des geistigen Aspektes shen aus der energetisch gesehen oberflächlicheren Extima und den Leitbahnen (Sinarteria) und/oder instabilen „Verankerung“ in der als tiefliegender angesehenen Organebene (Intima). Diese Pathologie kann durch eine individuelle Therapie in Form von Akupunkturprotokollen, Arzneimittelrezepturen, diätetischen Maßnahmen und Anpassung des Lebensstils therapiert werden.
Not as expected: the role of performance expectations in voter responses to election pledge fulfilment
Authors: Markwat Niels 
Published: February 2023

AbstractNot only the content, but also the context of election pledges should affect how voters respond to broken and fulfilled pledges. Borrowing from other disciplines, the hypotheses in this study propose that voters with low expectations reward pledge fulfilment more than voters with high expectations, while voters with high fulfilment expectations punish pledge-breakers more severely than voters with low expectations. A survey experiment using real-life political events was designed where 2465 respondents first received information that either significantly raised or lowered their expectations of pledge fulfilment. They were then presented with the actual fulfilment status of the pledge, either confirming or disconfirming their manipulated expectations, and asked to give their perceptions of the governing party’s performance. Interestingly, the findings support the presence of a confirmation, not a disconfirmation bias, suggesting that pledge performance attitudes are formed more similarly to other political attitudes than evaluations of private/public goods or services. Combined with a negativity bias in media coverage of election pledges, this confirmation bias in voters provides a partial explanation of the low esteem voters generally hold of governments’ pledge fulfilment. The results have implications for our understanding of how pledge fulfilment matters to voters, and how governments are held accountable for their performance.
Knowledge mapping of relative deprivation theory and its applicability in tourism research
Authors: Pan Jinyu , Yang Zhenzhi 
Published: February 2023

AbstractTourism research urgently requires the introduction of new theories to address current issues and challenges. Relative deprivation theory may be the key to effectively explaining the attitudes and behaviours of tourism multistakeholders and resolving tourism conflicts. This study uses CiteSpace to conduct a citation space analysis of relative deprivation theory and draws knowledge mappings to reveal its research foundation, research hotspots, and frontiers to discuss the practical possibility of its application to tourism research. The results show that the research content of relative deprivation theory involves 12 knowledge clusters, including subjective well-being, collective action, socioeconomic inequality, in-group attitudes, and relative deprivation theory, and that its theoretical framework is well suited to the context of tourism research. Tourism-related relative deprivation faces practical challenges and has the potential for theoretical innovation. This study focuses on the perceptions, attitudes, and behaviours of stakeholders and anticipates future research on tourism relative deprivation from the three aspects of multi-interest research subjects, multidimensional research contents, and multiperspective theoretical expansion, which indicate future research directions while revealing the possible innovation of relative deprivation theory.
Mood alternation in Mexican Spanish in Georgia
Authors: Bove Kathryn P. , Limerick Philip P. 
Published: February 2023

AbstractThe current study analyzes mood alternation in Spanish spoken in Georgia among first-generation Mexican immigrants. Using sociolinguistic interview data, tokens of the subjunctive and indicative in dependent clauses were examined, particularly in the following syntactic contexts:depender, aunque, me gusta que, no porque, quizás, tal vez,andno sé si/ cómo/dónde/qué. We argue that mood selection in the contexts under study is determined by the evaluation of the proposition in the dependent clause. We then use this data to inform theories of possible world semantics (i.e.,Anand and Hacquard 2013;Giannakidou and Mari 2021;Villalta 2008) to better understand mood alternation. Moreover, while many U.S. Spanish varieties may demonstrate what Silva-Corvalán (1994, 91) refers to as “a reduced system that made it more difficult to distinguish between more or less possible situations in a hypothetical world,” we show that cases of alternation in the present data still differentiate speaker meaning and evaluation.

Published: February 2023

Abstract
The whole natural complex, the system of using natural renewable natural resources depends on the state of the forestry sector of the national economy. Over the years of land reform, the area of the forest fund of Kazakhstan has more than doubled, as a result of which the search for ways to develop forestry enterprises in the country is becoming increasingly urgent. The purpose of the study is to consider the forest management and forestry units in the Republic of Kazakhstan. In the course of the study, the main indicators of the forest fund of the Republic of Kazakhstan in the period from 2015 to 2019 were analyzed. The study concludes that forestry in Kazakhstan should be aimed at protecting forests, increasing their area, and moving away from interest in forests as a source of forest resources.
Electroelastic metasurface with resonant piezoelectric shunts for tunable wavefront control
Authors: Lin Z , Tol S 
Published: February 2023

Abstract
In this paper, we design a tunable phase-modulated metasurface composed of periodically distributed piezoelectric patches with resonant-type shunt circuits. The electroelastic metasurface can control the wavefront of the lowest antisymmetric mode Lamb wave (A
0 mode) in a small footprint due to its subwavelength features. The fully coupled electromechanical model is established to study the transmission characteristics of the metasurface unit and validated through numerical and experimental studies. Based on the analysis of the metasurface unit, we first explore the performance of electroelastic metasurface with single-resonant shunts and then extend its capability with multi-resonant shunts. By only tuning the electric loads in the shunt circuits, we utilize the proposed metasurface to accomplish wave deflection and wave focusing of A
0 mode Lamb waves at different angles and focal points, respectively. Numerical simulations show that the metasurface with single-resonant shunts can deflect the wavefront of 5 kHz and 6 kHz flexural waves by desired angles with less than

2
%

deviation. In addition, it can be tuned to achieve nearly three times displacement amplification at the designed focal point for a wide range of angles from

−

∘

to 75∘. Furthermore, with multi-resonant shunts, the piezoelectric-based metasurface can accomplish anomalous wave control over flexural waves at multiple frequencies (i.e. simultaneously at 5 kHz and 10 kHz), developing new potentials toward a broad range of engineering applications such as demultiplexing various frequency components or guiding and focusing them at different positions.
Probe beam influence on spin polarization in spin-exchange relaxation-free co-magnetometers

Published: February 2023

Abstract
Spin-exchange relaxation-free (SERF) co-magnetometers have promising applications in both inertial navigation and fundamental physics experiments. However, the fluctuation in the spin polarization caused by the probe beam has a non-negligible influence on the co-magnetometer signal. In this paper, a theoretical model containing three parameters of the probe beam is established by extending the coupled Bloch equation. Based on this model, the influence of probe power density on the transient and steady-state response of the SERF co-magnetometer is analyzed. According to the transient response model, a new measurement method for transverse optical pumping of the probe beam is proposed. Then, for the steady-state response model, a steady-state error suppression method is suggested by adjusting the degree of circular polarization of the probe beam. Eventually, the suppression method is used to refine the SERF co-magnetometer, achieving a suppression rate of 70.31% in transverse electron spin polarization fluctuations, thus improving the co-magnetometer to a stability of 0.0079∘ h−1. To our knowledge, this is better than what has been reported so far.
Bi-filter multiscale-diversity-entropy-based weak feature extraction for a rotor-bearing system

Published: February 2023

Abstract
Multiscale-based entropy methods have proven to be a promising tool for extracting fault information due to their high feature extraction ability and easy application. Despite multiscale analysis showing great potential in extracting fault characteristics, it has some drawbacks, such as cutting the data length and neglecting high-frequency information. This paper proposes a bi-filter multiscale diversity entropy (BMDE) to filter comprehensive fault information and address the data length problem. First, the low-frequency information is filtered out by moving average in a multi-low procedure and the high-frequency information is filtered out by an adjacent subtraction in a multi-high procedure. Second, a modified coarse-grained process is introduced to overcome the issue of data length. The validity of the BMDE method is evaluated using both simulation signals and experimental measurements. Results demonstrate that the proposed method offers optimal feature extraction capability with the highest diagnostic accuracy compared with four other traditional entropy-based diagnosis methods.

Abstract
In this article we present an open source setup for measuring the acceleration due to gravity g utilising Faraday’s law of induction. The signal is acquired using an Arduino Uno board, then displayed and analysed using a Python based graphical user interface. The acceleration due to gravity g is calculated by measuring the crossing times of a bar magnet as it falls simultaneously through a number of coils.
Measuring the pressure inside a party balloon with a ruler

Published: February 2023

Abstract
We measure the radius of a party balloon after consecutive exhalations. We use the stress–strain relation for latex, and argue that the inflation is consistent with a constant volume of air exhaled in a single breath. We find its value and determine the gauge pressure of the balloon by applying the principle of least work. We compare elastic properties of party balloons with those of the aorta. The experiment illustrates methods from metrology in a context suitable for the introductory sequence.
