Cartoons on trial: a case study integrating discursive, legal and empirical perspectives
Authors: Pedrazzini Ana , Royaards Tjeerd
Published: August 2022

This paper focuses on two controversial cartoons that elicited debates around the conflicts between freedom of expression and the right to satire on the one hand, and the protection of the reputation or rights of others on the other. Paying special attention to genre-related aspects, we adopt a comprehensive approach that combines a discourse analysis of the cartoons, the analysis of the legal cases that followed their publication, and the assessment by 68 cartoonists from 33 nationalities on the clarity and offensiveness of the selected cartoons. The cartoons were published inCharlie Hebdo(France) andEl Universo(Ecuador), respectively. Based on our analyses, we propose that the main triggers of discursive controversy are the target as well as the modal and rhetorical ways of addressing a theme. We also conclude that: (1) The plaintiff’s most relevant arguments deny the satirical status of these cartoons; (2) The high disparity in the cartoonists’ assessments ofCharlie Hebdo’s cartoon can be associated with its ambiguity when addressing a sensitive issue; (3) Regardless of their positive or negative assessment, cartoonists have a strong position in defense of the authors’ and newspapers’ right to publish them; (4) No significant differences were found in the assessment of the cartoons in relation to the geographical origin of the cartoonists who took part in the questionnaire.

Authors: Mazhitova Aichurok T. , Kasymakunova Aidaikan M. , Turker Nuzhet
Published: August 2022

The suitability of mandarin (MP), orange (OP) and pomegranate peel powders (PP) for co-pigmentation of dewberry, viburnum, red hawthorn, black hawthorn, and barberry anthocyanins was investigated. Spectrophotometric measurements indicated co-pigmentation causing both a hyperchromic effect (ΔABSmax = 5–13) and bathochromic shift (Δλ
vis-max up to 13 nm). The degradation kinetics of anthocyanins were estimated at temperatures ranging from 70 to 90 °C. First-order reactions with rate constants of 0.45–2.93 min−1 and 0.30–2.00 min−1 were observed for the reference and PP co-pigmented samples, respectively. The t
1/2 values were 3.90–25.7 h for the reference and 5.8–38.5 h for the co-pigmented samples. The activation energy (E
a) values were higher in co-pigmented samples (49.16–77.77 kJ/mol) than in reference samples (41.82–68.75 kJ/mol), except for black hawthorn, which had a lower E
a value in the co-pigmented sample. The thermodynamic parameters (enthalpy, free energy, and entropy) evaluated indicated a positive effect of co-pigmentation on the thermal treatment of anthocyanins.
Indoleamine 2,3-dioxygenase controls purinergic receptor-mediated ischemia-reperfusion injury in renal tubular epithelial cells
Authors: Eleftheriadis Theodoros , Pissas Georgios , Golfinopoulos Spyridon , Liakopoulos Vassilios , Stefanidis Ioannis
Published: August 2022

Objectives

Ischemia–reperfusion (I–R) injury is the most common cause of acute kidney injury (AKI). Experimental studies have shown that indoleamine 2,3-dioxygenase 1 (IDO) and the purinergic receptor P2X7 contribute to kidney I–R injury. We evaluated whether there is an interplay between IDO and P2X7 in the pathogenesis of I–R injury.

Methods

Primary renal proximal tubular epithelial cells (RPTECs) were subjected to anoxia or reoxygenation with or without specific inhibitors. Cell imaging, colorimetric assays, and Western blotting were used.

Results

Cell imaging revealed that inhibition of IDO, or all the purinergic receptors with an ATPase, or specific inhibition of P2X7 rescued the cells from anoxia or reoxygenation-induced cell death. This was confirmed with LDH release assay, which also detected the ferroptotic nature of cell death due to reoxygenation. On the contrary, activated cleaved caspase 3 increased during anoxia, showing that apoptosis prevails. All the aforementioned treatments prevented caspase increase. Both anoxia and reoxygenation increased extracellular ATP, IDO, and P2X7 expression. IDO remained unaffected by the above-mentioned treatments. On the contrary, treatment with apyrase or inhibition of P2X7decreased extracellular ATP and P2X7 expression, which are also decreased by inhibition of IDO. The first indicates a positive feedback loop regarding P2X7 activation, expression and function, while the latter implies that IDO controls P2X7 expression.

Conclusions

In RPRECs subjected to anoxia or reoxygenation, IDO is upregulated, increasing P2X7 and contributing to anoxia or reoxygenation-induced cell death. Clarifying the molecular mechanisms implicated in kidney I–R injury is of particular interest since it may lead to new therapeutic strategies against AKI.
A neurotherapy protocol to remediate cognitive deficits after adjuvant chemotherapy: a pilot study
Authors: Sideroff Stephen , Wellisch David , Yarema Valerie
Published: August 2022

Objectives

Adjuvant chemotherapy for breast cancer is undeniably effective in increasing survival rates but many breast cancer survivors (BCS) exhibit side effects including nausea, fatigue, stress, and neurocognitive deficits, known as “chemobrain.” This pilot study explored how neurotherapy, or EEG biofeedback, a non-pharmacological approach, improved neurocognitive, behavioral, and neurophysiological deficits associated with BCS who underwent chemotherapy.

Methods

Subjects underwent 18 sessions of EEG biofeedback training, in which audio and visual feedback occurred with successful shifting of EEG patterns.

Results

Quantitative EEG and assessment tests demonstrated neurophysiological, cognitive, and behavioral deficits in all nine subjects prior to training. EEG biofeedback resulted in significant improvements in neurophysiological, neurocognitive, and psychological functions in all nine subjects after training.

Conclusions

We propose that this intervention and related forms of EEG biofeedback have the potential to significantly alleviate common side effects of chemotherapy in BCS and therefore merits additional research attention.
Asthma medications in schools: a cross-sectional analysis of the Asthma Call-back Survey 2017-2018
Authors: Wilkins Rachel , Schiffmacher Sadie , Gatewood Ashton , Conway Lauren , Greiner Ben , Hartwell Micah
Published: August 2022

Context

Asthma is the most common chronic disease affecting children in the United States. Goals for asthma management include symptom control, the ability to maintain a normal activity level, and minimizing adverse events.

Objectives

The objective of this study is to analyze the number of children with asthma that are permitted to carry medications at school and without an asthma action plan.

Methods

In this study, we analyzed the Center for Disease Control and Prevention (CDC) Asthma Call-back Survey (ACBS) to assess the prevalence of children in school allowed to carry medication and with asthma action plans. Utilizing the sampling weights provided, we estimated population prevalence by age group and urbanicity.

Results

Results showed that, overall, 34.8% of students reported they were not allowed to carry asthma medications in school. Specifically, nearly 51% of children ages 5 to 9 and 33% of children ages 10 to 14 were reported not to be allowed to carry medications at school. Further, 58.2% of children did not have a written asthma action plan. Reported urbanicity was not significantly associated with access to medication at school (p=0.46) or having an asthma action plan (p=0.57).

Conclusions

In our study, more than one-third of students were not permitted to carry asthma medications and nearly three-fifths did not have a written asthma action plan. Therefore, we recommend partnerships between schools, healthcare professionals, students, and osteopathic family physicians to increase access to asthma action plans and medication in schools.
Bad Facts and Principles: Finding the Right Kind of Fact-Insensitivity
Authors: Bojanowski Jochen
Published: August 2022

David Estlund holds that ultimate normative principles are insensitive to bad facts. This is a deliberately twisted appropriation of Jerry Cohen’s famous dictum that ultimate normative principles are fact-insensitive. In this paper, I will show why Estlund’s twist misses the point of Cohen’s argument. The fact-insensitivity claim is not a requirement to eliminate all facts from our normative theories because facts necessarily make these theories concessive. Instead, it may help us to locate the true origin of these concessions. In normative theorizing, we have not explained why a fact supports a principle if we fail to articulate the higher-order principle in light of which that fact is normatively significant.
Post-traumatic stress disorder: a psychiatric disorder requiring urgent attention
Authors: Du Jun , Diao Huapeng , Zhou Xiaojuan , Zhang Chunkui , Chen Yifei , Gao Yan , Wang Yizheng
Published: August 2022

Post-traumatic stress disorder (PTSD) is a severe and heterogenous psychiatric disorder that was first defined as a mental disorder in 1980. Currently, the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) and the International Classification of Diseases 11th Edition (ICD-11) offer the most widely accepted diagnostic guidelines for PTSD. In both diagnostic categories, experiencing a traumatic event (TE) is the necessary criterion for diagnosing PTSD. The TEs described in the DSM-5 include actual or threatened death, serious injury, sexual violence, and other extreme stressors, either directly or indirectly. More than 70% of adults worldwide are exposed to a TE at least once in their lifetime, and approximately 10% of individuals develop PTSD after experiencing a TE. The important features of PTSD are intrusion or re-experiencing fear memories, pervasive sense of threat, active avoidance, hyperarousal symptoms, and negative alterations of cognition and mood. Individuals with PTSD have high comorbidities with other psychiatric diseases, including major depressive disorder, generalized anxiety disorder, and substance use disorder. Multiple lines of evidence suggest that the pathophysiology of PTSD is complex, involving abnormal neural circuits, molecular mechanisms, and genetic mechanisms. A combination of both psychotherapy and pharmacotherapy is used to treat PTSD, but has limited efficacy in patients with refractory PTSD. Because of the high prevalence, heavy burden, and limited treatments, PTSD is a psychiatric disorder that requires urgent attention. In this review, we summarize and discuss the diagnosis, prevalence, TEs, pathophysiology, and treatments of PTSD and draw attention to its prevention.

Makkan Arabic does not have post-focus compression: a production and perception study
Authors: Alzaidi Muhammad Swaileh
Published: August 2022

Post-focus compression (PFC), in which words following focus are compressed inF0and intensity, is recently found to be effective in encoding focus. Recent studies find that PFC is present in Egyptian, Hijazi and Lebanese Arabic, and hence they are classified as +PFC languages. However, there are languages from the same family language which differ mainly in terms of the presence and absence of PFC. The current study investigated the production and perception of prosodic focus marking in Makkan Arabic, an under-researched Arabic dialect. Systematic acoustic analyses and statistical tests show that (a) the on-focus word is realized by expanding the excursion size, increasing theF0and strengthening the intensity of its stressed syllable, (b) information and contrastive focus are not prosodically distinguishable, (c) Makkan Arabic lacks PFC, and (d) focus recognition is low compared to Hijazi Arabic (+PFC), Taiwanese and Taiwan Mandarin (other −PFC languages). The new findings, taken together with recent findings, suggest that (1) the prosodic encoding of focus is different across Arabic dialects productively and perceptually, and (2) the on-focus raising is not a sufficient factor in recognizing prosodic cues to focus. These results contribute to broadening our understanding of different prosodic focus markings cross-linguistically and cross-dialectally.
The effect of feeding location on the continuous precipitation of Pu(IV) oxalate in a vortex precipitator
Authors: Li Chuanbo , Wang Bo , Ouyang Yinggen , Yan Taihong , Zheng Weifang
Published: August 2022

The effects of feeding location on crystals size and distribution, precipitation percentage of Pu(IV) oxalate were investigated in a vortex continuous precipitator when the apparent average residence time was 25 min at 50 °C. The results showed that when oxalic acid was into the free vortex zone and Pu(IV) nitrate solution was into the forced vortex one, the VMD of the particles near the outlet of the precipitator increased from 36.8 ± 1.2 µm to 45.8 ± 2.1 µm, the precipitation percentage of Pu(IV) oxalate from 97.90% ± 1.0–99.79% ± 0.05%, compared with another feeding location, both oxalic acid and Pu(IV) nitrate solution into the forced vortex zone. The two feeding methods could both prevent Pu(IV) oxalate nuclei contacting the inner wall of the precipitator during nucleation. The results showed agglomeration happened during crystals growth even under stirring. Both local supersaturations and agglomeration decided particles size distribution and the average size of Pu(IV) oxalate.
Health Care Provider Networks: Are Insurers Better Off?
Authors: Mougeot Michel , Naegelen Florence
Published: August 2022

Certain health insurers offer a free choice of providers and an identical copayment regardless of the provider. Others build networks and use selective contracting and financial incentives to channel policyholders to contracted suppliers. In the case of unregulated prices, we compare these two policies when the off-network medical service is not covered. We show how policy ranking depends on the characteristics of demand. If demand is linear, a for-profit insurer and a not-for-profit insurer obtain a higher profit and utility under selective contracting than under uniform reimbursement. In the constant elasticity case, these results do not hold. Insurers prefer uniform reimbursement while consumers are better off under selective contracting in both cases.
Distinct characteristics of correlation analysis at the single-cell and the population level
Authors: Wu Guoyu , Li Yuchao
Published: August 2022

Correlation analysis is widely used in biological studies to infer molecular relationships within biological networks. Recently, single-cell analysis has drawn tremendous interests, for its ability to obtain high-resolution molecular phenotypes. It turns out that there is little overlap of co-expressed genes identified in single-cell level investigations with that of population level investigations. However, the nature of the relationship of correlations between single-cell and population levels remains unclear. In this manuscript, we aimed to unveil the origin of the differences between the correlation coefficients at the single-cell level and that at the population level, and bridge the gap between them. Through developing formulations to link correlations at the single-cell and the population level, we illustrated that aggregated correlations could be stronger, weaker or equal to the corresponding individual correlations, depending on the variations and the correlations within the population. When the correlation within the population is weaker than the individual correlation, the aggregated correlation is stronger than the corresponding individual correlation. Besides, our data indicated that aggregated correlation is more likely to be stronger than the corresponding individual correlation, and it was rare to find gene-pairs exclusively strongly correlated at the single-cell level. Through a bottom-up approach to model interactions between molecules in a signaling cascade or a multi-regulator-controlled gene expression, we surprisingly found that the existence of interaction between two components could not be excluded simply based on their low correlation coefficients, suggesting a reconsideration of connectivity within biological networks which was derived solely from correlation analysis. We also investigated the impact of technical random measurement errors on the correlation coefficients for the single-cell level and the population level. The results indicate that the aggregated correlation is relatively robust and less affected. Because of the heterogeneity among single cells, correlation coefficients calculated based on data of the single-cell level might be different from that of the population level. Depending on the specific question we are asking, proper sampling and normalization procedure should be done before we draw any conclusions.
“Hypophora” and “question cascade” in Cantonese political discourse: the stance triangle and the use of rhetorical moves and utterance final particles
Authors: Wan Helen
Published: August 2022

This paper looks into the specific pragmatic functions of Cantonese utterance final particles (UFPs) employed in a televised political debate, hosted by the Television Broadcasts Limited in 2016. The paper explores the most frequently used UFPs and discusses how they are being manipulated with two prominent questioning strategies, i.e., hypophora and question cascade, to help project negative stance in this highly institutionalized discourse genre. With the aid of the theoretical framework of ‘stance triangle’, I investigate how various stance-taking activities are navigated through the employment of two questioning strategies as well as UFPs to establish dis-alignment among the electoral candidates. The findings show that the most frequently used UFPs are le1 and aa3: these two UFPs are relatively neutral in question design in daily conversation and are used in all types of question such as polar questions, alternative questions, and content questions. The findings demonstrate that these particles serve as a mitigator and softener with the strategic use of hypophora and question cascade. This paper also proposes a revised stance triangle that helps understand how the negative stances are navigated in questioning strategies and realize the stance objects in an explicit manner. Discovering the true stance objects reveals that the question designs are usually oriented to the “remote audiences,”i.e. the voters.
A bibliographic survey of the supramolecular architectures sustained by delocalised C–I⋯π(arene) interactions in metal-organic crystals
Authors: Tiekink Edward R. T.
Published: August 2022

A survey of the crystallographic literature of metal-organic crystal structures for the presence of C–I···π(arene) interactions where the iodide atom occupies a position close to plumb to the ring centroid, corresponding to a delocalised interaction, and is within the assumed sum of the van der Waals radii, i.e. 3.88 Å, has been undertaken. The majority of the 26 identified examples feature supramolecular chains of varying topology whereby C–I···π(arene) contacts are readily identified and apparently operating independently of other obvious supramolecular synthons. The next most prevalent supramolecular aggregate was zero-dimensional, containing up to a maximum of three molecules. While there were three examples of two-dimensional arrays among a series of isostructural crystal structures, no examples of three-dimensional structures largely sustained by C–I···π(arene) interactions were noted. This distribution of supramolecular aggregation patterns matched that noted for all-organic systems. In terms of the overall adoption rate, delocalised C–I···π(arene) interactions were found in 3% of crystals of metal-organic species where they could form, a percentage lower than 4% noted for all-organic crystals.

Davies, TB, Halaki, M, Orr, R, Mitchell, L, Helms, ER, Clarke, J, and Hackett, DA. Effect of set structure on upper-body muscular hypertrophy and performance in recreationally trained men and women. J Strength Cond Res 36(8): 2176–2185, 2022—This study explored the effect of volume-equated traditional-set and cluster-set structures on muscular hypertrophy and performance after high-load resistance training manipulating the bench press exercise. Twenty-one recreationally trained subjects (12 men and 9 women) performed a 3-week familiarization phase and were then randomized into one of two 8-week upper-body and lower-body split programs occurring over 3 and then progressing to 4 sessions per week. Subjects performed 4 sets of 5 repetitions at 85% one repetition maximum (1RM) using a traditional-set structure (TRAD, n = 10), which involved 5 minutes of interset rest only, or a cluster-set structure, which included 30-second inter-repetition rest and 3 minutes of interset rest (CLUS, n = 11). A 1RM bench press, repetitions to failure at 70% 1RM, regional muscle thickness, and dual-energy x-ray absorptiometry were used to estimate changes in muscular strength, local muscular endurance, regional muscular hypertrophy, and body composition, respectively. Velocity loss was assessed using a linear position transducer at the intervention midpoint. TRAD demonstrated a significantly greater velocity loss magnitude (g = 1.50) and muscle thickness of the proximal pectoralis major (g = −0.34) compared with CLUS. There were no significant differences between groups for the remaining outcomes, although a small effect size favoring TRAD was observed for the middle region of the pectoralis major (g = −0.25). It seems that the greater velocity losses during sets observed in traditional-set compared with cluster-set structures may promote superior muscular hypertrophy within specific regions of the pectoralis major in recreationally trained subjects.
Physiological Feature Recognition Algorithm of Human Exercise-Induced Fatigue Based on Parameter Analysis of Nanomachine Simulation for a Future Smart World
Authors: Chen Yujue , Hu He , Li Qiang
Published: August 2022

Traditional methods cannot fully reflect the fatigue degree of human exercise through a single parameter, which has the problems of long recognition time, high recognition coincidence, and poor anti-interference. Therefore, a physiological feature recognition algorithm of human exercise-induced fatigue based on parameter analysis of nanomachine simulation is proposed. The output value of body weight and a three-axis acceleration sensor are used to calculate the energy consumption parameters. By judging the time series period of fatigue physiological features data, the physiological features of human exercise-induced fatigue are extracted, and the feature extraction results are fused. According to the fusion results, the feature recognition is realized by analyzing the simulation parameters of nanomachine. The experimental results show that the shortest feature recognition time of the proposed method is 2.35 s, which is significantly lower than that of the traditional method, the feature recognition coincidence degree of the proposed method is lower, and the anti-interference performance is better, which fully shows that the method can accurately judge the degree of human exercise-induced fatigue.
Vom Überschreiten der „Schattenlinie“. Zur Aktions- und Handlungsforschung der 1970er Jahre im Spannungsfeld von Theorie und Praxis
Authors: Haupt Selma , Zenke Christian Timo
Published: August 2022

Starting from the discussion on the theory- practice relation in educational science, this article focuses on the tradition of action research, particularly in the course of the 1970s. Using the example of Laborschule Bielefeld, a state-run experimental school, it examines the challenges that arise in the attempt to fundamentally question the boundaries between theory and practice in the mode of action research. Not only does it become apparent that the tension between theory and practice cannot be completely resolved – even if an attempt is made to resolve it constructively in a group of “teacher researchers” who act as autonomously as possible – but the fundamental difficulties of participatory research in the field of pedagogy are revealed.

Dissolved organic carbon (DOC) produced by primary production in the sunlit ocean can be physically transported to the mesopelagic zone. The majority of DOC exported to this zone is remineralized by heterotrophic microbes over a range of timescales. Capturing a deep convective mixing event is rare, as is observing how microbes respond in situ to the exported DOC. Here, we report ship and Argo float observations from hydrostation North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) 2 Station 4 (N2S4; 47.46°N, 38.72°W), a retentive anticyclonic eddy in the subtropical region of the western North Atlantic. Changes in biogeochemistry and bacterioplankton responses were tracked as the water column mixed to approximately 230 m and restratified over the subsequent 3 days. Over this period, rapid changes in bacterioplankton production (BP) and cell abundance were observed throughout the water column. BP increased by 91% in the euphotic zone (0–100 m) and 55% in the upper mesopelagic zone (100–200 m), corresponding to 33% and 103% increases in cell abundance, respectively. Within the upper mesopelagic, BP upon the occupation of N2S4 (20 ± 4.7 nmol C L–1 d–1) was significantly greater than the average upper mesopelagic BP rate (2.0 ± 1.6 nmol C L–1 h–1) at other stations that had been stratified for longer periods of time. BP continued to increase to 31 ± 3.0 nmol C L–1 d–1 over the 3-day occupation of N2S4. The rapid changes in BP in the upper mesopelagic did not coincide with rapid changes in community composition, but the taxa that increased in their relative contribution included those typically observed in the epipelagic zone. We interpret the subtle but significant community structure dynamics at N2S4 to reflect how injection of labile organic matter into the upper mesopelagic zone by physical mixing supports continued growth of euphotic zone-associated bacterioplankton lineages on a timescale of days.
Luminescence thermometry based on downshifting and upconversion photoluminescence of Bi4Ti3O12:Yb3+/Pr3+ ceramic
Authors: Liu Z. , Wang R. X.
Published: August 2022

Yb3+/Pr3+ codoped Bi4Ti3O12 (abbreviated as Bi4Ti3O12:Yb3+/Pr3+) ceramic was successfully fabricated by solid state sintering method. The structural, morphological and luminescence properties were investigated by X-Ray diffraction, scanning electron microscopy, steady-state downshifting and upconversion photoluminescence spectra. Green and red downshifting emissions can be effectively excited by 450 nm blue light irradiation. The intensity ratios of downshifting green and red emissions are sensitive to temperature. The spectral positions of downshifting green and red emissions show blue-shift with elevation of temperature. Under 980 nm excitation, the tempreature dependent upconversion photoluminescence were recorded. Based on fluorescence intensity ratio of 545 nm and 623 nm in upconversion emission spectra, temperature sensing was achieved with maximum absolute sensitivity value of 0.0068 K-1 at 443 K. These results show Bi4Ti3O12:Yb3+/Pr3+ ceramic is a promising candidate for luminescence thermometry, which may find its applications in the scientific research and industry.

Published: August 2022

This study describes the fabrication and characterization of PVP and PVP/La thin films from a mixture of high molecular weight polyvinylpyrrolidone (PVP) and (1, 2, and 3)% lanthanum chloride using an electrospinning process on glass and silicon. It includes an N- type (Si) (111) substrate at room temperature. Field Emission Scanning Electron Microscopy (FESEM) analysis reveals fibers with an average diameter in the range of 125-250 nm. The mean fiber diameter decreases with increasing concentration (La). The optical energy gap was determined from the analysis of the transmission spectrum in the UV-visible region. The optical gap (Eg) gradually decreases from 4 eV to 3.64 eV for undoped PVP films due to the increase in La ion content at 3%, which determines the feasibility of using these obtained fibers in the manufacturing process. PVP/La nanofibers as detectors.
Effects of Sr2+ on the properties of layered perovskite structured Ba1-xSrxTi4O9 ceramics

Published: August 2022

The Phase, microstructural and dielectric properties of Ba1-xSrxTi4O9 (0 ≤ x ≤ 0.8) ceramics were investigated. The XRD analysis revealed the formation of orthorhombic structured (Pnmm) BaTi4O9 phase. The XRD peaks were observed to shift towards the lower 2θ values with increasing Sr2+ contents which may be attributed to the substitution of relatively larger cation of Sr2+ (RSr = 1.61 Å) for Ba2+ (RBa = 1.44 Å) in BaTi4O9. The dielectric constant (εr) increased with Sr2+ substitution from 22 to 122 at 1MHz. The maximum value of the dielectric loss was observed 0.11922 for x = 0.8 at 1 MHz.
Dormancy release in diaspores of Butia yatay (Arecaceae) using scarification and warm stratification
Authors: Santos Marina Remião Dos , Schlindwein Gilson , Tonietto Adilson , de Oliveira Juliano Morales
Published: August 2022

Butia yatay (Arecaceae) is a threatened palm that occurs naturally in native grasslands of southern Brazil. Its fruits are an alternative source of income for the local populations with potential for agro-industry. This generates a demand for seedlings that is limited by the
difficult propagation due to the dormancy of the seeds. Thus, this work aimed to develop a method capable of accelerating germination by overcoming dormancy. Pyrenes from four inflorescences were harvested from different trees in the municipality of Três de Maio/ Brazil. In the first
experiment, the pyrenes were warm-stratified at 40°C for 0 (control), 1, 2, 3 or 4 weeks. In experiment 2, pyrenes scarified manually (removal of the endocarp germ pore) or using H2 SO4 for 5 or 10 minutes were subsequently warm-stratified for four weeks. In experiment
3, pyrenes subjected to physical scarification were warm-stratified for 4, 5, 6 or 8 weeks. Analyses showed that there was a significant effect of the preheating and scarification treatments on the emergence of B. yatay seedlings. Pyrenes mechanically scarified (opening of the germ
pore) and subsequently subjected to preheating at 40°C for five weeks produced the highest speed of emergence index, with about 28 seedlings emerged from 100 sown pyrenes.
Computer modeling of electromechanical system of two-speed elevator

Published: August 2022

Today, elevator production in Ukraine needs innovative solutions and changes, because most of the equipment in operation was built and installed in the 70-80s of the last century. Due to the high cost of new frequency-controlled winches and the complexity of maintenance, the search for modernization and improvement of existing elevator winches remains an alternative. No less important stage of operation is diagnostics. Timely detection of damages and forecasting of future failures allow to provide high-quality work during all term of operation, and also to reduce expenses of budgetary funds for difficult repairs. Computer simulation playsan important role in the modern world both during the design of a new elevator and during operation. Thanks to fairly simple and clear programs, it is possible to reproduce not only the standard modes of operation of the mechanisms, but also to perform calculations of future possible faults. The use of visualization facilitates the perception of information for operators, engineers and other users involved. The paper presents a computer model of a two-speed elevator with an induction motor and a reduction winch. The research used Matlab / Simulink software, which is intuitive to use and, in the full sense of the word, informative. The built model of the elevator has feedback on the calculated load of the cabin. The latter is determined by the transients during engine start-up and affects the positioning accuracy at a stop. The dependences of the influence of the degree of cab loading on the positioning accuracy are found. In the second stage, the supply voltage parameter is added. A change in this parameter within ± 10% affected the previous calculations of the loading degree and deteriorated the accuracy by almost three times.At the same time, most indicators (75%) meet the requirements of international standards EN 81-20: 2014 with positioning accuracy in the range of ± 10 mm. In further studies it is planned to use the obtained results to reduce the sensitivity of the algorithm for calculating theloadingdegree of the cabin to change the supply voltage and ensure the required positioning accuracy in the entire load range of the cabin when changing the supply voltage ± 10%.
Comparative analysis of classifiers for face recognition on image fragments identified by the FaceNet neural network
Authors: Polyakova Marina V. , Kozak Dmitry Yu. , Huliaieva Natalia A.
Published: August 2022

As a result of the analysis of the literature, the based methods of face recognition on fragments of color images were identified. These are flexible comparison in graphs, hidden Markov models, principal component analysis, and neural network methods. The analyzed methods of face recognition are mainly characterized by significant computational costs and low recognition performance. An exception is the neural network methods of face recognition, which, after completing the training, make it possible to obtain a high recognition performance at low computational costs. However, when changing the prototype images of faces, it often becomes necessary to redefine the network architecture and retrain the network. The specificity of neural network methods is also the complexity of selecting the network architecture and its training. Such papers are devoted to the use of neural networks onlyfor extraction of feature vectors of face images. The classification of the obtained feature vectors is then performed by knownmethods, namely, thresholding, a linear support vector machine, nearest neighbors, random forest. It has been observed that the lighting conditions in which the images were obtained and the turning of the head affect the shape of the separating surface and can decrease the feature vector classification performance for face images. Therefore, to improve the classification performance, it was decided to use correlation for prototype matching, a non-linear support vector machine and logistic regression. The performed experiment showed that correlation for prototype matching of low-light face images is characterized by higher classification performance compared to the thresholding. Moreover, the use of the Pearson and Spearman correlation coefficients showed similar results, and when using the Kendall correlation coefficient, the worst classification performance was obtained compared to the Pearson andSpearman coefficients. The research of the classification performance of images of faces that differ in head turn using correlation for prototype matching, a non-linear support vector machine and logistic regression showed the following. Correlation for prototype matching is more appropriate to use with small amounts of data due to the high classification performance and low computational complexity, since a small amount of data does not require a significant number of comparisons. However, on large amounts of data, the non-linear support vector machine requires less computation and shows similar classification performance. Using the results of the experiment, the researcher can select classification methods for a specific set of face images, preliminarily representing them with feature vectors using the network FaceNet.
Developing method of vector synthesis deductive logic forcomputer systems fault analysis
Authors: Hahanova Anna V.
Published: August 2022

The article is devoted to the development of models and methods for fault analysisfor examinate testpatterns.Deductive fault simulationof digital devices is the most advanced technology that serves the field of design and testing of modern computer systems. Atthe same time, fault simulation solves the problem of assessing the quality of the test in the class of single constant defects. However, the computational complexity of obtaining deductive formulas, estimated as n3, is a rather difficult task for high-dimensional RTL-level functional circuits, so the deductive method is usually used only for digital circuits represented at the gate level. Next, we propose a vector method for synthesis deductive formulas for digital schemes represented by RTL elements. This method became possible due to the element description of any complexity in the form ofoutput states vector forcombinational device.The model of xor-relationships between the wonderful logical functions (or, xor, and) of digital objects is improved, which is convolutedinto zero-space. Itmakes possible to solve the problems of design and test, machine learning, search for similarities-differences, and destructive components in processes and phenomena. The advantages of the vector model for a compact description of objects, functions and structures are determined. It is proposed to replace analytical expressions thatrequire algorithmically complex calculating, with vector data structures for describing functional logic. Vector-deductive method for synthesisformulas fortransporting input fault lists is proposed.Ithas a quadratic computational complexity of register operations. The coordinate-vector model of defects is considered, not tied to input variables, which can be used for efficient processing of complex logic circuits when assessing the quality of synthesized tests. An algorithm for the synthesis of deductive vectors is presented, which differs from the known ones in the technological parallel processing simplicity of truth tables and makes it possible to create structural and logical conditions for simulating faults in digital projects of the gate, register and system description levels. An efficient method for the synthesis of a deductive truth table according to the rule L=T⊕F is proposed.Itdiffers from the known ones by using vector-coordinate parallel xor-operation.Itprovidesthe transportation of faults through a functional element of arbitrary complexity.
Conservative management of complicated Rathke’s cleft cyst mimicking pituitary apoplexy
Authors: Constantinescu S M , Wilms G , Furnica R M , Duprez T , Maiter D
Published: August 2022

Complicated Rathke’s cleft cyst (RCC) is a rare occurrence of symptomatic bleeding or growth of a previously asymptomatic (and often undiagnosed) intrasellar cyst derived from remnants of Rathke’s pouch, situated on the midline between the adeno- and neurohypophysis. Symptoms may be identical to those of pituitary apoplexy: acute onset of headache, hypopituitarism, and neurological disturbances. Both syndromes may also exhibit a similar appearance of a large haemorrhagic sellar mass at initial radiological evaluation. We report on two patients who presented with headache and complete hypopituitarism. Based on the initial MRI, they were first diagnosed with pituitary apoplexy but managed conservatively with hormone therapy alone because of the absence of severe visual or neurological threat. Upon follow-up at 4 months, clinical evolution was good in both patients but their pituitary mass had not reduced in size and, after careful radiologic reviewing, was more indicative of a large midline complicated RCC. In conclusion, the diagnosis of complicated RCC is challenging because it can mimic pituitary apoplexy clinically, biologically, and radiologically. Clinicians should distinguish between the two entities using specific radiological signs or evolution of the mass at MRI if the patient does not undergo surgery. To our knowledge, we report conservative management of this rare condition for the first time, though it seems appropriate in the absence of neurological compromise or visual compression. Long-term follow-up is however mandatory.

Learning points

Complicated Rathke’s cleft cyst can mimic pituitary apoplexy, presenting with sudden onset of headache, hypopituitarism, and visual and neurological compromise in the most severe cases.

At diagnosis, pituitary MRI may not be able to differentiate between the two entities, showing a large haemorrhagic mass inside the sella, with little or no normal pituitary tissue visible. Patients are often diagnosed with apoplexy at this stage and may undergo pituitary surgery.

When surgery has not been performed initially in these patients, repeat imaging at 3–6 months is unchanged and does not show the expected involution usually seen after adenoma apoplexy.

Conservative management with hormonal replacement seems a valid option in the absence of visual or neurological deficits that would require trans-sphenoidal surgery.

Die Beiträge im zweiten Band der Schriftenreihe Kulturelles Erbe in der digitalen Welt der Deutschen Digitalen Bibliothek zeigen auf, wie in Deutschland mit seiner föderalen Ordnung die Vermittlung und letztlich Vernetzung des kulturellen Erbes über das Internet angegangen wird. In ihnen finden sich Informationen zum organisatorischen Aufbau und der Infrastruktur der Digitalisierung und zu Kooperationen und politischen Rahmenbedingungen. Die Beiträge setzen die politische Agenda ins Verhältnis zum tatsächlich Erreichten, beschreiben den Stand der Umsetzung, geben Auskunft über Digitalisierungsstellen, Projekte und deren Koordination, beschreiben die institutionellen Zuständigkeiten, erläutern Portale und die Zusammenarbeit mit der Deutschen Digitalen Bibliothek, enthalten Ausführungen zur Langzeitarchivierung: Und am Ende wird jeweils auch ein Ausblick gewagt. Beispiele für Konzepte außerhalb Deutschlands runden das Bild ab. Waren es im ersten Band Der Vergangenheit eine Zukunft Fragen nach öffentlicher Verantwortung, gesellschaftlichen Aufgaben und privatem Engagement, stehen nun die Strategien der Bundesländer für das kulturelle Erbe in der digitalen Welt im Vordergrund.
Tactics against Antiquity
Authors: Koutsomichalis Marinos
Published: August 2022

This essay outlines an empirical endeavour pivoting on the contemporaneity of the ruins of ancient Messene (Greece) by means of an eclectic method and in a situated artistic context. Drawing inspiration from the “peripatetic” tradition, the project concerns a technologically mediated soundwalk through the ruins which foregrounds Messene (a) as a place that is practised sociopolitically in the present as a way to generate cultural and historical content, and (b) as a vibrant habitat that hosts a wide range of entwined beings, things, energies and phenomena. A mixed method focused on technologies for mediation and the researcher’s body as the centre of the project’s inquiry is proposed, so as to produce an experience that is evocative of an emergent multitemporality specific to this place while also making accessible to the senses the plurality of objects and geophysical phenomena that manifest at the site. The project is contextualised with respect to experimental, creative, performative and “punk” archaeology, as well as to object-oriented and new materialist trends. It presents the resulting narrative, discusses how it relates to various sociopolitical/historical contexts and details the method and its constituent elements. The provided illustrations document the composed soundwalk and the creative tactics at play.
Helping EAL academics navigate asymmetrical power relations in co-authorship
Authors: Khuder Baraa , Petrić Bojana
Published: August 2022

This paper presents, discusses, and evaluates research-based materials for English for Research Publication Purposes (ERPP) teaching, based on a study conducted with exiled academics supported by CARA (Council for At-Risk Academics) and their UK-based co-authors who provided textual interventions on their texts. Using data from interviews with exiled academics and their UK-based co-authors/mentors as well as their article drafts and textual interventions, we present teaching materials for ERPP workshops aimed at raising the participants’ awareness of issues that may arise in co-authorship involving asymmetrical power relations, such as those between exiled academics and their UK-based co-authors/mentors. The materials take the shape of data-based scenarios which ask workshop attendees to consider experiential co-authorship narratives involving (i) the issue of ‘parochialism’, i.e., failure to indicate the relevance of one’s research to a larger audience, (ii) issues with the type and amount of feedback regarding writer development and text production, (iii) blurred lines of co-authorship roles, and (iv) authority issues in interdisciplinary collaborative writing. Each scenario is followed by a research-informed discussion. We argue that scenario-based awareness-raising activities can sensitize all parties in asymmetrical co-authorship pairs/groups to common challenges that arise in such collaborations, help them navigate collaborative writing successfully, and encourage them to reflect on their own co-authorship practices. We conclude by discussing the merits of the scenario-based approach to developing materials for ERPP teaching.
Bachelor’s thesis writing as an emotional process
Authors: Rantala-Lehtola Kati , Ruohotie-Lyhty Maria
Published: August 2022

This study explores the bachelor’s thesis writing process from the perspective of emotions by using a holistic, narrative approach to individual development. Emotions are analysed in interconnection with implicit conceptions about academic writing and about oneself as a writer. The process of academic writing is described as a movement where balancing positive and negative emotions is one part of academic multiliteracy. The data of the study include visual, textual, and interview data from different phases of the bachelor’s thesis process. In the analysis, four types of narratives of thesis writing are created: growth, survival, project, and conflict narratives. The study offers a holistic perspective to academic writing and provides writing instructors and students with ways to identify emotions and implicit beliefs related to writing processes.
