The great auk in Norway: From common to locally extinct
Authors: Hufthammer Anne Karin , Hufthammer Karl Ove 
Published: September 2022

AbstractA total of 477 bones of the great auk (Pinguinus impennis) from 53 localities and 55 periods in Norway are studied. All but two, are archaeological sites from the Holocene, mainly from 6000–2000 cal years bp. The two non‐anthropogenic sites date to the Ice Age: probably 36,000–34,500 and 14,690–12,890 years bp. The bones are mainly unburned and well preserved but fractured. Except for the open‐air sites in northern Norway, the bones are mainly from rock‐shelters and caves. In combining archive data, chronological information, and morphometrical studies, we suggest the great auk disappeared from the most southern part of Norway (and Sweden and Denmark) prior to 4000 years bp: a decline in distribution 2000 years ago: It became absent from the Norwegian coast 1000 years ago. Data suggest that it was distributed on the coast and in the fjord systems in winter and early spring. The presence of bones of juveniles/subadults indicates that it was also distributed in northern Norway in the autumn. To evaluate possible size differences, in time and space, nine bone elements have been measured according to standard recommendations. Multiple imputation was used to handle missing data before any statistical analysis. Analyses indicate that bones from Nordland are larger than from the rest of the country, while bones from the northernmost sites are smaller. At some localities, size differences, especially in total length of the bones, are found. It has not been verified if this is due to individual variation or sexual differences. The great auk became extinct in the 19th century. The study supports the theory that human predation at breeding sites was the main cause of its extinction.

Published: September 2022

AbstractCellular polymers, such as polyethylene foams, are commonly used in the packaging industry. These materials have short service life and generate a high volume of waste after use. In order to valorize this waste and produce added‐value applications, it is proposed to convert these materials into highly efficient energy absorption structures. This was done by modifying the original cellular morphology of the foams (spheroidal or polygonal) into a re‐entrant structure to produce auxetic materials. This work presents an optimized process combining mechanical compression and solvent vapor evaporation‐condensation leading to low density foams (77–200 kg/m3) having negative Poisson's ratios (NPR). Three series of recycled low density polyethylene (LDPE) foams with an initial density of 16, 21, and 36 kg/m3were used to optimize the processing conditions in terms of treatment temperature, time, and pressure. From all the samples prepared, a minimum Poisson's ratio of −3.5 was obtained. To further characterize the samples, the final foam structure was analyzed to relate with mechanical properties and compare with conventional foams having positive Poisson's ratios. The results are discussed using tensile properties and energy dissipation which were shown to be highly improved for auxetic foams. Overall, the resulting foams can be used in several applications such as sport and military protection equipment.
Related research between college students' mobile game addiction, mobile self‐efficacy, and academic performance in Taiwan
Authors: Chu Kuo‐Ming 
Published: September 2022

AbstractAs a novel type of mobile game, addictive behavior has attracted the attention of researchers due to its possible negative impacts on several forms of psychological problems. In this research, we tested the relationship between academic performance, mobile game addiction (MGA), and mobile self‐efficacy among undergraduates in Taiwan. An academic model has been suggested from the hypotheses and using a sample of 739 college students by estimating the structural equation modeling. This result discloses that college students are an at‐risk swarm for the MGA. We realized that MGA was negatively connected with academic performance and mobile self‐efficacy, exhibiting a positive relationship between the latter two. Further analysis on age, place of stay, and the duration of playing mobile games distinction was tested in the trajectories from MGA to these psychological health results, and the results revealed that they were significantly associated with MGA. We also dealt with the limitations and recommended that the authorities immediately regard this, and to complete academic goals, college students should refrain from playing mobile games and participate in other forms of healthy entertainment.
Characterization of ancestral Fe/Mn superoxide dismutases indicates their cambialistic origin
Authors: Valenti Rosario , Jabłońska Jagoda , Tawfik Dan S. 
Published: September 2022

AbstractSuperoxide dismutases (SODs) are critical metalloenzymes mitigating the damages of the modern oxygenated world. However, the emergence of one family of SODs, the Fe/Mn SOD, has been recurrently proposed to predate the great oxygenation event (GOE). This ancient family lacks metal binding selectivity, but displays strong catalytic selectivity. Therefore, some homologues would only be active when bound to Fe or Mn, although others, dubbed cambialistic, would function when loaded with either ion. This posed the longstanding question about the identity of the cognate metal ion of the first SODs to emerge. In this work, we utilize ancestral sequence reconstruction techniques to infer the earliest SODs. We show that the “ancestors” are active in vivo and in vitro. Further, we test their metal specificity and demonstrate that they are cambialistic in nature. Our findings shed light on how the predicted Last Common Universal Ancestor was capable of dealing with decomposition of the superoxide anion, and the early relationship between life, oxygen, and metal ion availability.
Adaptive impulsive security consensus control of uncertain multi‐agent systems with randomly occurring nonlinearities
Authors: Li Junhui , Ren Chang‐E , Chen C. L. Philip 
Published: September 2022

AbstractIn practice, deception attacks, uncertainties, and randomly occurring nonlinearities (RONs) in multi‐agent systems (MASs) are ubiquitous. Consequently, this paper settles the problem of secure consensus tracking control for uncertain MASs with randomly occurring nonlinearities under sensor attacks by adopting adaptive impulsive control methods. Compared with the previous works, a class of state‐dependent sensor attack is firstly considered in the impulsive control. Meanwhile, a novel adaptive algorithm is introduced to deal with unknown system matrices, randomly occurring nonlinearities and uncertain parameters caused by sensor attacks. Sufficient conditions are derived to achieve leader‐following consensus for the MASs by adaptive impulsive control under sensor attacks. Lastly, two simulation examples illustrate the validity of theorems in this paper.

Published: September 2022

AbstractAn integrated multi‐criteria analysis framework was proposed for the sustainable water management of built reservoir with dam‐heightening‐based decision, which enhances the conventional decision‐making methods by more reasonably quantifying the decision‐making process. The method utilizes a group of techniques involving game theory, analytic hierarchy process (AHP) identifying and considering different stakeholder groups, entropy weight, and fuzzy comprehensive evaluation (GAEF), and is applied to the largest water transfer programs in China. The study results showed that the improved multi‐criteria decision framework can well deal with the decision‐making problem of built reservoir construction scheme in facing the newly increased task of water transfer. The study identifies five stakeholders that affect the subjective weight of the heightening schemes of built reservoir for inter‐basin water transfer. It was revealed that the game theory can better couple the collective wisdom of large complex groups and the objectivity of indicators than traditional methods such as geometric average. This study is of high reference value for the feasibility demonstration of built reservoir with dam‐heightening‐based decision around the world to achieve the water related Sustainable Development Goals (SDGs), especially for those reservoirs with water transferring tasks.
Blast performance and analysis of reinforced concrete beams subjected to corrosion of the longitudinal reinforcement

Published: September 2022

AbstractThis research has investigated the effect of reinforcement corrosion on the flexural response of reinforced concrete beams subjected to blast loading. Five beams, with and without corrosion, were tested under blast loads using a shock‐tube. The corroded specimens were subjected to an accelerated corrosion regime prior to testing, with a mass loss of up to 22% in the longitudinal steel reinforcement over the mid‐span or full‐span regions. A companion set of two beams was tested under quasi‐static four‐point bending. The results from the static tests show that corrosion of the longitudinal reinforcement decreased the strength and ductility, and ultimately changed the failure mode from ductile to brittle. Under blast loading, the steel corrosion increased maximum displacements and support rotations, reduced blast capacity, increased damage and fragmentation, and led to more brittle failure as the % mass loss increased. The effects of corrosion on blast response were moderate when the steel was corroded over the full‐span region. Furthermore, the blast response of the beams was predicted using dynamic inelastic single‐degree‐of‐freedom (SDOF) analysis, with the resistance functions developed using 2D finite element modeling, while accounting for the reduction in steel stress–strain properties and corrosion‐induced cracking. The SDOF analysis showed acceptable results in terms of ability to predict maximum displacements of the flexural‐governed beams (corroded and un‐corroded).
Kardiale MRT bei nichtischämischen Kardiomyopathien
Authors: Lücke Christian , Gutberlet Matthias 
Published: September 2022

Zusammenfassung
Hintergrund
Die in Deutschland angewandte Einteilung der Kardiomyopathien geht auf die Klassifikation der Europäischen Gesellschaft für Kardiologie (ESC) von 2008 zurück. Dort werden sie nach ihrem Phänotyp unterteilt, so dass die Magnetresonanztomographie (MRT) in der Lage ist, die unterschiedlichen Kardiomyopathien zu differenzieren.

Bildgebung und Differenzialdiagnostik
Die Stärke der MRT ist es, anhand der Möglichkeiten der Gewebsdifferenzierung nichtischämische Kardiomyopathien von anderen Erkrankungen mit ähnlichen morphofunktionellen Aspekten zu differenzieren. So gelingt im Fall der dilatativen Kardiomyopathie (DCM) eine Differenzierung zur inflammatorischen DCM. Im Fall der hypertrophen Kardiomyopathie (HCM) kann analog zur Echographie eine obstruktive und nichtobstruktive Form differenziert werden, aber auch die Detektion einer Amyloidose oder eines Morbus Fabry ist möglich. Die Evaluation der rechtsventrikulären Funktion gelingt im Rahmen einer arrhythmogenen rechtsventrikulären Kardiomyopathie (ARVC) zuverlässig. Außerdem ist die MRT in der Lage, die charakteristische fettige Ersatzfibrose direkt nachzuweisen. Bei den seltenen restriktiven Kardiomyopathien kann sie die Restriktion nachvollziehen und z. B. mittels T1-, T2- und T2*-Mapping die Sphingolipid-Akkumulation im Myokard bei einem Morbus Fabry oder eine Eisenüberladung bei Hämochromatose nachvollziehen.

Innovationen
Die quantitativen Verfahren des parametrischen Mappings bieten die Möglichkeit eines Therapiemonitorings; die klinische Relevanz dieses Monitorings ist aber noch Gegenstand aktueller Forschung. Die unklassifizierten Kardiomyopathien können sich klinisch mit ähnlicher Symptomatik wie ischämische oder inflammatorische Erkrankungen präsentieren, so dass im Fall eines Myokardinfarkts ohne verschlossene Koronararterien („myocardial infarction without obstructive coronary arteries“, MINOCA) in der Herzkatheteruntersuchung die MRT ein entscheidendes diagnostisches Instrument ist, um die tatsächlich zugrundeliegende Erkrankung festzustellen. Gleichermaßen kann sie bei neuen Kardiomyopathien wie der Non-compaction-Kardiomyopathie der Wegbereiter für eine morphologische Krankheitsdefinition sein.

AbstractEffects of ascorbate (ASA) and hydrogen peroxide (H2O2) on metabolite profile was compared in wheat. Interestingly, the redox environment became more oxidized after ASA treatment and more reduced after H2O2 addition based on the ratios of oxidised and reduced ascorbate and glutathione. The excess of ASA could inhibit, while H2O2 could induce the oxidative pentose phosphate pathway producing reducing power as shown by the unchanged and decreased glucose-6-phosphate content, respectively. This different effect on glucose-6-phosphate content can also explain the reduced formation of several amino acids from the intermediate products of glycolysis after ASA treatment and their constant or greater levels after H2O2 addition. In contrast to most amino acids, the accumulation of Pro was greatly induced by ASA, and this change was fivefold greater than after H2O2 addition. This difference could also contribute to the distinct redox shifts after the two treatments, since NADPH is oxidised during Pro synthesis. The more oxidising environment after ASA treatment activated several transcripts related to the ascorbate–glutathione cycle and the pentose phosphate pathway. Our results indicate the overcompensating effect of ASA and H2O2 on the redox environment in leaf tissues and the subsequent different adjustment of metabolite profile and the related transcript levels.

Published: September 2022

AbstractDespite of growing evidence of the beneficial effects of placental transfusion techniques, there is no available sufficient data about their effects on vulnerable hemodynamics and myocardium of premature infants. The purpose of this work is to study ventricular functions and hemodynamics after applying different placental transfusion techniques, delayed cord clamping (DCC), cut cord milking (C-UCM), and intact cord milking (I-UCM). Sixty-four infants delivered whether by C-section or vaginal delivery were randomly assigned to undergo C-UCM (20–30 cm), I-UCM (3–4 strippings), and DCC (30–60 s). Functional echocardiography was done on day 1 and day 3 of life for 57 infants. Primary outcome variable was superior vena cava flow measurement in infants having placental transfusion in the first 24 h of life and between 64 and 72 h. Secondary outcomes were other echocardiographic and clinical hemodynamic parameters, and biventricular functions in those infants. Of a total 196 preterm infants ≤ 32 weeks delivered in the study period, from January 2021 to August 2021, 57 infants were eligible and survived till the second examination. They were randomly assigned to the three groups. Neonates randomly assigned to DCC had significantly higher superior vena cava flow and lower right ventricular systolic function in the first 24 h of life. This finding vanished at day 3. Neonates undergone different methods of placental transfusions had similar hemoglobin, admission temperature, and mean blood pressure in the first 24 h of life.Conclusion: Despite their potential benefits, placental transfusions have shown to alter the hemodynamics and adversely affect myocardial function of premature neonates.Trial registration: This trial was registered in the clinical trial gov NCT04811872.

What is Known:• Placental transfusion techniques might have benefits regarding prematurity- related morbidities and mortality.

What is New:• Placental transfusion might adversely affect the myocardium and alter hemodynamics in premature infants.
Can spa rehabilitative interventions play a role for patients suffering from neurodegenerative disorders at the early stages? A scoping review
Authors: Maccarone Maria Chiara , Masiero Stefano 
Published: September 2022

AbstractThe global burden of neurodegenerative disorders is significantly increasing as life expectancy rises but currently there is no cure for these conditions. An extensive search on MEDLINE (PubMed) and PEDro databases was conducted selecting clinical trials, Randomized Controlled Trials, and longitudinal studies published in the last 20 years in order to highlight what evidence there is for a role of spa rehabilitative interventions for patients with neurodegenerative diseases, in terms of motor function, symptoms, and quality of life (QoL) improvement and cost-effectiveness. A total of 225 publications were analyzed. Only three manuscripts were selected for review because they matched the inclusion criteria. These studies demonstrated statistically significant differences in the outcomes evaluated among patients affected by Parkinson’s disease after thermal rehabilitative treatments: motor function, balance, QoL, and psychological well-being statistically improved. In addition, rehabilitation in the spa setting seemed to be cost-effective for these patients. However, further studies are needed to define the role of spa rehabilitative interventions for these patients as the literature is still limited.

Published: September 2022

AbstractDiscrimination has a negative impact on mental health and wellbeing of persons affected. The aim of the present study was to investigate perceived discrimination of migrant adolescents. Focus groups with migrant adolescents were conducted, audio-recorded and transcribed verbatim. The transcripts were analyzed using the manifest qualitative content analysis by Mayring. The foci of interest (persons discriminated against and by whom, where and how the discrimination took place, which behavioral and emotional reactions the affected persons showed to the experiences and which reasons they assumed for the discrimination) were determined based on the pre-defined guideline, and inductive subcategories were extracted from the transcripts and grouped into main categories. Five focus groups with students with migration background (n = 35, 13 females, mean age: 18.78, SD = 2.26, range 16–24) were conducted. The adolescents in our focus groups and their acquaintances (families and friends) experienced discrimination in Germany in several forms (verbal and non-verbal), places and on an individual as well as institutional level, with an impact on their emotional well-being. To combat discrimination, culturally sensitive information must be provided on the part of those affected as well as their perpetrators.
Challenges and future directions for energy, latency, and lifetime improvements in NVMs
Authors: Kargar Saeed , Nawab Faisal 
Published: September 2022

AbstractRecently, non-volatile memory (NVM) technology has revolutionized the landscape of memory systems. With many advantages, such as non volatility and near zero standby power consumption, these byte-addressable memory technologies are taking the place of DRAMs. Nonetheless, they also present some limitations, such as limited write endurance, which hinders their widespread use in today’s systems. Furthermore, adjusting current data management systems to embrace these new memory technologies and all their potential is proving to be a nontrivial task. Because of this, a substantial amount of research has been done, from both the database community and the storage systems community, that tries to improve various aspects of NVMs to integrate these technologies into the memory hierarchy. In this work, which is the extended version of Kargar and Nawab (Proc. VLDB Endowment 14(12):3194–3197, 2021), we explore state-of-the-art work on deploying NVMs in database and storage systems communities and the ways their limitations are being handled within these communities. In particular, we focus on (1) the challenges that are related to high energy consumption, low write endurance and asymmetric read/write costs and (2) how these challenges can be solved using hardware and software solutions, especially by reducing the number of bit flips in write operations. We believe that this area has not gained enough attention in the data management community and this tutorial will provide information on how to integrate recent advances from the NVM storage community into existing and future data management systems.

AbstractIn this study, site-specific natural background levels (NBLs) were determined for 18 elements (Al, As, Be, Cd, Co, Cu, Cr, Fe, Hg, K, Mn, Mo, Ni, Pb, Tl, U, V, and Zn) in two sediment cores collected offshore the Bagnoli-Coroglio brownfield site (Gulf of Pozzuoli, southern Italy) to accurately assess the degree of contamination and the historical trends in Heavy Metals (HMs) enrichment. This objective was pursued taking in account the high temporal and spatial variability of the geochemical properties of the area due to the local geothermal activity. Moreover, the temporal variation of Polycyclic Aromatic Hydrocarbons (PAHs) was investigated.226Ra was used as an extraordinary marker to confirm 210Pb dating. It especially allowed defining the geochronological framework of the sediment core closer the brownfield up to around 1500, providing compelling support to correlate the investigated elements’ occurrences with natural geogenic dynamic. Sediment samples were accurately dated and analyzed for chemical and particle size composition. The contamination factor (Cf) and the pollution load index (PLI) showed very high enrichment of Cd, Cu, Hg, Pb, and Zn. The contamination profiles of HMs and PAHs follow the same pattern in both sediment cores, increasing from deep to upper layers. The highest contamination levels for HMs and PAHs were observed between 10 and 30 cm, corresponding to the periods of most intense industrial activity. Decreasing trends of pollutants were observed in the surface layers (0–10 cm), probably affected by a natural attenuation process due to the cessation of industrial activities.
