AbstractLittle is known how acute exercise‐induced inflammation and metabolic stress affect immune cell bioenergetics and the portion of its components. Therefore, we investigated acute effects of eccentric‐only (E), concentric‐only (C) and combined eccentric‐concentric resistance exercise (E + C) bouts on cellular respiration of peripheral blood mononuclear cells (PBMCs). Twelve strength‐trained young men performed bench press resistance exercises in randomized order. Venous blood samples were drawn at pre‐, 5 min post‐ and 24 h post‐exercise. Several PBMC respiration states were measured using high‐resolution respirometry. Levels of leukocytes, interleukin 6 (IL‐6), C‐reactive protein (CRP), creatine kinase (CK), blood lactate and maximum voluntary isometric force were measured from the same time points. Effects of blood lactate and pH change on bioenergetics of PBMCs were investigated ex vivo. PBMC routine respiration (p = 0.017), free routine capacity (p = 0.025) and ET‐capacity (p = 0.038) decreased immediately after E + C. E responded in opposite manner 5 min post‐exercise compared to E + C (p = 0.013) and C (p = 0.032) in routine respiration, and to E + C in free routine activity (p = 0.013). E + C > C > E was observed for increased lactate levels and decreased isometric force that correlated with routine respiration (R = −0.369, p = 0.035; R = 0.352, p = 0.048). Lactate and pH change did not affect bioenergetics of PBMCs. Acute resistance exercise affected cellular respiration of PBMCs, with training volume and the amount of metabolic stress appear influential. Results suggest that acute inflammation response does not contribute to changes seen in cellular respiration, but the level of peripheral muscle fatigue and metabolic stress could be explaining factors.
Mandatory Dematerialization of Shares in Polish Private Companies: A Missed Opportunity to Do Things Right
Authors: Dybiński Jacek , Weber Anne-Marie 
Published: July 2022

Abstract

On 1 March 2021, Polish company law underwent a profound change when the reform introducing the mandatory dematerialization of shares in non-listed companies entered into force. On that day, share certificates became ex lege invalid and were replaced by entries into electronic share registers or securities accounts held by investment firms. With this step, the legislator dealt the nearly-final blow to document securities in Poland, given that the publicly-traded shares have already been subject to dematerialization since 1997 and most of other securities, both listed and non-listed, followed suit in recent years. Like in various jurisdictions which had gone through this process before, the Polish legislator had several options regarding the electronic securities regulation. The article analyses the essential features of the reform and puts it in a broader, comparative context. It also aims to assess whether the new law responds to theoretical and practical challenges inherent to electronic securities in times of innovative financial technologies and fast-changing legislation. The authors argue that an electronically registered share is de facto a new type of a dematerialized security that the reform added to the current catalogue, but its normative design is incomplete and far from what should be expected given the importance of its regulation in company law.
Regulatory Barriers to Corporate Restructuring Through Disposition of Major Assets – A Serbian Perspective*
Authors: Radović Mirjana , Radović Vuk 
Published: July 2022

Abstract

This article contains a critical analysis of the existing Serbian legal provisions that limit the possibility of a major asset disposition as a way of restructuring companies. In this regard, the authors have identified three main problems affecting such asset deals in Serbia, which can be considered regulatory barriers to this type of restructuring. The three problems are: the specific regulation of necessary shareholder approval and appraisal rights, the unavoidable assumption of liabilities by the purchaser (the buyer or the transferee) and the inadequate implementation of the EU Transfer of Undertakings Directive concerning employee protection. The solutions adopted in Serbian law are analyzed using a comparative approach, especially based on the rules adopted in Europe, including South-East Europe and the U. S. as a reference. It is interesting to show how different influences from these other jurisdictions have led to the specific (unique) development of the Serbian regulation with regard to dispositions of major assets. The ultimate goal of the present article is to examine the possibility and the need for harmonization of these issues on the regional (supranational) level.
EnvironZen: Immersive Soundscapes via Augmented Footstep Sounds in Urban Areas
Authors: Schrapel Maximilian , Happe Janko , Rohs Michael 
Published: July 2022

Abstract
Urban environments are often characterized by loud and annoying sounds. Noise-cancelling headphones can suppress negative influences and superimpose the acoustic environment with audio-augmented realities (AAR). So far, AAR exhibited limited interactivity, e. g., being influenced by the location of the listener. In this paper we explore the superimposition of synchronized, augmented footstep sounds in urban AAR environments with noise-cancelling headphones. In an online survey, participants rated different soundscapes and sound augmentations. This served as a basis for selecting and designing soundscapes and augmentations for a subsequent in-situ field study in an urban environment with 16 participants. We found that the synchronous footstep feedback of our application EnvironZen contributes to creating a relaxing and immersive soundscape. Furthermore, we found that slightly delaying footstep feedback can be used to slow down walking and that particular footstep sounds can serve as intuitive navigation cues.
Ethical, Legal & Participatory Concerns in the Development of Human-Robot Interaction

Published: July 2022

Abstract
Research on Human-Robot Interaction is increasing as system become widely available and reached a level that enables smooth interactions. Yet, many research projects act in a silo mentality, in regard of participatory, ethical, or legal matters of social robotics. Knowledge about specific challenges is not universal and has often to be transferred from non-robotic contexts. We present findings in the three dimensions: participatory design, ethics for social robots and legal aspects. We accompanied eight research projects on social robots in real-world scenarios for three years. During that time, we spoke, observed, and helped (where possible) the research projects. This gave us specific insights into their work. Our findings work in three dimensions. In participatory design we observed that the trust relationship to users is essential to gain truthful insights and that a mixed method approach is promising. Regarding ethical aspects, we could see that ethical matters should be answered early on. And in the legal dimensions we noticed that the GDPR regulations are a challenge that often requires the help of experts. This work is reflecting on the observation of eight projects and is collecting lessons learned to help future projects and to learn from previous work.

Edge detection using nonlinear structure tensor
Authors: Yuan Shuping , Chen Yang , Ye Chengqiong , Ansari Mohd Dilshad 
Published: July 2022

Abstract
In order to improve the performance of edge detection for noisy images, a new edge detection method based on nonlinear structure tensor is proposed. First, the tensor product of noisy images is calculated. The tensor product is diffused according to the image gradient, which depends on the tensor product itself. Finally, the eigenvalues and eigenvectors of the diffusion tensor product are calculated, and the edges of the image are detected according to the eigenvalues. The method is compared with other methods. The experimental results show that the average number of edge points detected by method 1, method 2, method 3, and this method are 513.7, 530.0, 509.0, and 719.3, respectively. The average detection time of method 1, method 2, method 3, and this method were 65.3, 54.9, 57.3, and 33.6 s, respectively. When the number of edge detection is the largest, the average detection time of this method is significantly smaller than that of the three comparison methods. Therefore, this method is more suitable for edge detection of noisy images, and the performance of this method is better than that of the comparison method and can improve the performance of edge detection of noisy images.
Angle error control model of laser profilometer contact measurement
Authors: Guan Banggui , Qin Yanfu , Guo Minglei 
Published: July 2022

Abstract
In controlling the angle error of laser profilometer contact measurement, the control model used in the past is subject to more external interference, which affects the measurement of other parameters, resulting in poor error control effect. Therefore, the angle error control model of laser profilometer contact measurement is designed by determining the initial zero position of the profilometer measuring sensor, compensating the non-linear error, designing the interference signal processing circuit, and avoiding the error measurement influenced by external factors. From the main error sources such as the perpendicularity, standard error, sensor error and other errors of the coordinate axis of the profilometer, the accuracy is distributed. According to the equal action principle, the measurement uncertainty of the profilometer is calculated, and the measurement is obtained. According to the interference signal processing circuit and measurement index, the serial communication control circuit is designed, and the angle error control model of laser profilometer contact measurement is constructed. The experimental results show that the designed laser profilometer contact measurement angle error control model has high precision and does not affect other parameters in the control process, which shows that the control model has good effect in practical application.

Abstract
A new fluorescent sensor, N-allyl-4-[(2-(3-methoxysalicylaldimino)ethylamino]-1,8-naphthalimide (HL), for Hg2+ has been developed where the Schiff base substituent acts as a recognition group. This sensor shows a large Stokes shift of 3535–4042 cm−1 and a general fluorescence quantum yield of 0.05, 249–0.11, 866 in organic solvents of different polarity as expected. It also exhibits highly selective and a sensitive response to Hg2+ (Ф
Hg+HL/Ф
HL = 2.28) over other metal ions (Na+, K+, Ca2+, Mg2+, Al3+, Pb2+, Fe3+, Ni2+, Zn2+, Cu2+, Ag+, Co2+, Cr3+, Mn2+ and Cd2+) in solution (DMF/Tris-HCl buffer, 1:1, v/v, pH = 7.2). The Hg2+-induced fluorescence enhancement at 526 nm is proportional to the concentration of Hg2+ in the range of 0.5–4.0 µm with a detection limit of 0.18 µm. Based on the fluorescence titration and a Job’s plot analysis, the metal-to-ligand ratio of the complex is 2:1 with a binding constant of 1.56 × 1012 m

Published: July 2022

This paper discussed the implementation of the new MABIMS hilāl visibility criteria in the unification of the Hijriyah calendar in member countries (Malaysia, Brunei, Indonesia and Singapore). This research uses the approach of Astronomy and Grindle's theory of policy implementation. The data source comes from the MABIMS Muzakarah results document and related articles. The research results indicate that the new MABIMS moon crescent visibility criteria are part of a public policy that, in its implementation, requires two mutually supportive variables. First, the content of the policy in the form of the moon crescent visibility criteria (3⁰; 6.4⁰) was accepted by all member countries through the signing of an ad referendum on 8 December 2021. This acceptance will receive public support if it is beneficial to time management. Second, the context of implementation is carried out in stages by taking into the characteristics of the institutions involved in preparing the Hijriyah calendar. At the practical level, the policy can be well received by the public, except in Indonesia, which still faces obstacles. This is due to the policy in the three countries being carried out on a top-down basis, while in Indonesia, it is carried out on a bottom-up basis. Furthermore, determining of Ramadan, Shawwal, and Zulhijjah are still waiting for confirmation of the sighting of the moon (ru’yah). It related to the domination of ru’yah, and a strong distinction between the function of the calendar in civil administration and worship practice. Abstrak Makalah ini membahas penerapan kriteria baru visibilitas hilalMABIMS dalam penyatuan penanggalan Hijriyah di negara-negara anggota(Malaysia, Brunei, Indonesia dan Singapura). Penelitian ini menggunakanpendekatan penerapan kebijakan Astronomi dan teori Grindle. Sumber databerasal dari dokumen hasil Muzakarah MABIMS dan artikel terkait. Hasilpenelitian menunjukkan bahwa kriteria baru visibilitas hilal MABIMS merupakanbagian dari kebijakan publik yang dalam pelaksanaannya membutuhkandua variabel yang saling mendukung. Pertama, isi kebijakan berupa kriteriavisibilitas bulan sabit (3⁰; 6.4⁰) diterima oleh seluruh negara anggota melaluipenandatanganan referendum pada 8 Desember 2021. Penerimaan ini akanmendapat dukungan publik jika bermanfaat hingga manajemen waktu. Kedua,konteks pelaksanaannya dilakukan secara bertahap dengan memperhatikankarakteristik lembaga yang terlibat dalam penyusunan penanggalan Hijriyah.Pada tataran praktis, kebijakan tersebut dapat diterima dengan baik olehmasyarakat, kecuali di Indonesia yang masih menghadapi kendala. Hal inidisebabkan kebijakan di ketiga negara dilakukan secara top-down, sedangkan diIndonesia dilakukan secara bottom-up. Selanjutnya, penentuan awal Ramadan,Syawal dan Zulhijah masih menunggu konfirmasi penampakan hilal (rukyah).Ini terkait dengan dominasi ru’yah, dan perbedaan yang kuat antara fungsipenanggalan dalam administrasi sipil dan praktik ibadah.
Knowledge of teachers about suicidal behavior in adolescents
Authors: Soja Santos Laura Maria , Wesner Ana Cristina , Algeri Simone , MariaZarth Silvana 
Published: July 2022

Objective. To identify the knowledge of teachers about suicidal behavior in adolescents.
Methods. Qualitative exploratory-descriptive study conducted in a state school in the municipality of Porto Alegre, RS, Brazil. Twelve teachers participated in the study. Data were collected through semi-structured interviews analyzed using Bardin’s Content Analysis.
Results. Three categories were built: "Warning signs of suicide", related to the signs identified by the professionals; "Risk factors for suicide", which indicate the reasons that may lead adolescents to present this type of behavior; and "Difficulties in dealing with the behaviors", referring to the behaviors adopted by adolescents and the difficulties of teachers before the theme.
Conclusion. It was possible to identify that teachers recognize some signs of suicidal behavior, as well as some risk factors. Nonetheless, it is necessary to qualify them to approach the subject, since they feel insecure to act in more critical moments, thus generating mainly feelings of sadness, guilt and powerlessness.

Published: July 2022

Objective. To understand the experiences and perceptions of care dyads (person and caregiver) when having a permanent discharge ostomy.
Methods. Meta-synthesis that followed the ENTREQ standards and was registered in PROSPERO CRD42020221755; It was developed in three phases: (i). Search for studies in academic search engines, with MeSH terms: [(Patients) AND (Ostomy)) AND (Caregivers)], including qualitative primary studies published between 2000 and 2020; (ii). Assessment of the methodological quality with the CORE-Q instrument and the credibility of qualitative findings under the guidelines of the Johanna Briggs Institute; and (iii). Comparative analysis according to the guidelines by Sandelowski and Barroso.
Results. The work identified 664 studies; in screening, 35 passed to full-text analysis; 22 to methodological quality evaluation; and 10 to meta-synthesis. The study found 43 qualitative findings that constituted four categories: dyads perform instrumental and emotional care; ambivalent family caregiving feelings and actions; assertive and effective family care; and rejection of bodily changes and sexual dysfunction. These categories constitute the central meta-theme: “The dyads experience a life rupture, which is restored in a sea of ​ambivalent ​emotions and learning; at the same time, affective, instrumental and assertive care is constructed”.
Conclusions: People who experience having a permanent discharge ostomy express their rejection to the change in bodily image, alterations in sexual life and as a couple. Caregivers and families are the main source of support by being facilitators in self-care, through relationships of mutuality and reciprocity.
Treason by Bilingualism? Xenophobia, Clique, and the Impeachment of Yu Jing
Authors: Yue Isaac 
Published: July 2022

A gifted linguist, diplomat, and negotiator, Yu Jing (1000-1064) is uniquely qualified among Northern Song officials in his extensive knowledge of Khitan language and culture. At a time when Liao-Song relationship was at its most contentious, the advantage of having an official who could communicate fluently in both languages cannot be overstated. However, according to official history, not only did his bilingualism not endear him to the court, it aroused constant suspicion and led to his eventual impeachment, which occurred after he composed a poem in the Khitan language and presented it to the Emperor of the Liao State as a token of gratitude. The purpose of this paper is to reexamine the cause of Yu Jing’s indictment in the context of political machination. By contextualizing his compositionof the Poem in the Language of the Barbarianand subsequent impeachment within the politicsof the court, my goal is to supplement, evenchallenge, our above conventional acceptance ofxenophobia as the sole cause of Yu’s downfall. Indoing so, I hope to point out the potential flawof our current understanding of Song diplomacyas guilelessly dictated by its inferiority complexand0xenophobic sentiments.
The “classifier” Category in Mandarin Chinese and Other Languages
Authors: Martínez Consuelo Marco 
Published: July 2022

This paper contextualizes Mandarin Chinese within the general framework of the “classifier languages” of the world: Asian, Oceanic, Amerindian and African languages. It demonstrates that there are indeed many similarities among them, despite being geographically separated and not having any type of relationship. It continues analyzing the concept of "classifier" and the various types of classifiers in Chinese (individual, collective, partitive, temporary and standard or measure words), and comparing them with lexical and grammatical resources used in the Spanish language to express sense (recategorization) it resorts to some sort of "classifier". This paper demonstrates how “gender”in European languages is a grammar concept, semantically empty, so it should never be confused witha “classifier”. It recognizes how sometimes the overuse of classifier turns them into mere morphemesdevoid of meaning, and other times keeps alive their semantic strength and continue denoting someperceived or imputed feature of the referent. This paper concludes by rejecting two widespread ideas:1. The “primitivism” of classifier languages (against greater mental, logical and abstract developmentof the Indo-European languages). 2. The determinism in the categorization of the world and creationof a world view, as classifiers are conventional, with a strictly semantic role, but not cognitive nordeterministic.

В роботах проф. Павлова О. А. та його учнів ефективно вирішена проблема оцінки коефіцієнтів при нелінійних членах БПР з заданою малою дисперсією помилки (при умові точного розв’язання відповідних невироджених систем лінійних рівнянь). В цьому випадку гарантовано з надлишкового опису виключаються зайві нелінійні члени БПР. Задача, яка розв’язується у цій роботі, полягає у знаходженні обґрунтованого методавизначення зайвих лінійних членів БПР, заданої надлишковим описом, при використанні загального методу найменших квадратів при умові відомої (можливо, з точністю до невідомих числових значень її параметрів) функції щільності випадкової величини, що адитивно накладається на результати вимірювань вихідної змінної.
