Sustainable soil management measures: a synthesis of stakeholder recommendations
Authors: Strauss Veronika , Paul Carsten , Dönmez Cenk , Löbmann Michael , Helming Katharina
Published: February 2023

Soil degradation threatens agricultural production and soil multifunctionality. Efforts for private and public governance are increasingly emerging to leverage sustainable soil management. They require consensus across science, policy, and practice about what sustainable soil management entails. Such agreement does not yet exist to a sufficient extent in agronomic terms; what is lacking is a concise list of soil management measures that enjoy broad support among all stakeholders, and evidence on the question what hampers their implementation by farmers. We therefore screened stakeholder documents from public governance institutions, nongovernmental organizations, the agricultural industry, and conventional and organic farmer associations for recommendations related to agricultural soil management in Germany. Out of 46 recommended measures in total, we compiled a shortlist of the seven most consensual ones: (1) structural landscape elements, (2) organic fertilization, (3) diversified crop rotation, (4) permanent soil cover, (5) conservation tillage, (6) reduced soil loads, and (7) optimized timing of wheeling. Together, these measures support all agricultural soil functions, and address all major soil threats except soil contamination. Implementation barriers were identified with the aid of an online survey among farmers (n = 78). Results showed that a vast majority of farmers (> 80%) approved of all measures. Barriers were mostly considered to be economic and in some cases technological, while missing knowledge or other factors were less relevant. Barriers were stronger for those measures that cannot be implemented in isolation, but require a systemic diversification of the production system. This is especially the case for measures that are simultaneously beneficial to many soil functions (measures 2, 3, and 4). Results confirm the need for a diversification of the agricultural system in order to meet challenges of food security and climate change. The shortlist presents the first integrative compilation of sustainable soil management measures supporting the design of effective public or private governance.

Authors: Molin Bernard
Published: January 2023

Newly updated and translated into English for the first time, this standalone handbook perfectly combines background and theory with real-world experiments. All key topics are covered, including environmental conditions, wave theories, hydrostatics, and wave and current loads, with emphasis on nonlinear wave body interaction. Focus is given to model testing, an important component in the design of offshore structures. Recent results on the hydrodynamics of perforated structures, moonpool and gap resonance, and third-order interaction effects, have been added to this updated version. Based on practical experience from multiple industry collaborations, combined with lectures that have been honed and improved over more than 30 years, the pedagogical, real-world approach in this book make it an ideal companion for graduate students and researchers as well as ocean engineers.
Iridescent Beetle Adornments Suggest Incipient Status Competition among the Earliest Horticulturalists in Bears Ears National Monument
Authors: Terlep Michael L. , Smiley Francis E. , Haas Randall
Published: February 2023

Anthropological research has long theorized that emergent food-producing economies catalyzed high levels of inequality in human societies, as evident in the earliest use of jewelry made from gold, copper, and other precious minerals among early agricultural populations. Although the US Southwest appears to have been an exception, we report the discovery of two Basketmaker II period necklaces constructed of green iridescent scarab beetle femora, which suggests a homologous association between emergent agriculture and inequality. Drawing insight from ethnography, archaeology, entomology, and evolutionary ecology, we hypothesize that these and other jewelry items of Basketmaker II culture were visually prominent, honest signals of socioeconomic capital that emerged during a period of surplus food production and incipient wealth accumulation. It appears that Basketmaker II societies—like other emergent food-producing economies around the world—grappled with the opportunities and challenges that arise with surplus production, albeit in a distinct way that involved visually striking insect and feather adornments as status signals. Archaeologists may have previously overlooked this behavior due to Western biases that privilege precious metals and minerals as prestige objects and archaeological biases that tend to view insects as food or agents of site disturbance.
Moral Disjunction and Role Coadunation in Business and the Professions
Authors: Mota Rita , Morrison Alan D.
Published: January 2023

We consider the problem of moral disjunction in professional and business activities from a virtue-ethical perspective. Moral disjunction arises when the behavioral demands of a role conflict with personal morality; it is an important problem because most people in modern societies occupy several complex roles that can cause this clash to occur. We argue that moral disjunction, and the psychological mechanisms that people use to cope with it, are problematic because they make it hard to pursue virtue and to live with integrity. We present role coadunation as a process with epistemic and behavioral aspects that people can use to resolve moral disjunction with integrity. When role coadunation is successful, it enables people to live virtuous lives of appropriate narrative disunity and to honor their identity-conferring commitments. We show how role coadunation can be facilitated by interpretive communities and discuss the emergence and ideal features of those communities.
“May We Not Write Our Own Fairy Tales and Make Black Beautiful?” African American Teachers, Children's Literature, and the Construction of Race in the Curriculum, 1920–1945
Authors: Nocera Amato
Published: February 2023

This article examines children's literature written by African American teachers during the first part of the twentieth century. Drawing on theories of racialization, I analyze children's books written by two African American teachers: Helen Adele Whiting (1885-1959) and Jane Dabney Shackelford (1895-1979). I argue that their books represented more than an effort toward greater Black representation in schools; they also served as a contribution to a larger discourse on Blackness and identity that emerged during the “New Negro” movement. In this view, African American teachers were not mere passive recipients of an outside Black culture, but rather intellectual actors involved in the production of racial identity during the interwar period.
PRIVATIZATION OF AGER IN AFRICA FROM 123 TO 63 b.c.
Authors: Kim Yeong-Chei
Published: January 2023

Scholars have generally underestimated the level of Roman involvement in Africa in the period between the annexation of Carthage in 146 b.c. and Caesar's victory at Thapsus in 46 b.c., and the land in Africa which the Romans annexed has been conventionally called public land (ager publicus). This paper analyses the surviving text of the African provisions of the epigraphic lex agraria of 111 b.c. and notes that the term ager publicus is not attested in the provincial section of the law. The land in Africa appears simply as ager in Africa and the term ager publicus is confined exclusively to Italy in the law of 111. However, Cicero's references to Rullus’ agrarian proposal in 64/3 b.c. in the De lege agraria suggest that the term ager publicus was used to qualify land existing outside Italy in Rullus’ proposal. This paper argues that the concept of ager publicus as opposed to private land developed in Africa between 111 and 63 b.c., and that this was linked to privatization of ager in Africa in this period. The results of this study suggest a high degree of Roman exploitation of African land prior to the Caesarean and Augustan colonies in the 40s b.c.
Taking Over the Size Effect: Asset Pricing Implications of Merger Activity
Authors: Easterwood Sara , Netter Jeffry , Paye Bradley , Stegemoller Michael
Published: January 2023

We show that merger announcement returns account for virtually all of the measured size premium. An empirical proxy for ex ante takeover exposure positively and robustly relates to cross-sectional expected returns. The relation between size and expected returns becomes positive or insignificant, rather than negative, conditional on this takeover characteristic. Asset pricing models that include a factor based on the takeover characteristic outperform otherwise similar models that include the conventional size factor. We conclude that the takeover factor should replace the conventional size factor in benchmark asset pricing models.
Threats to state survival as emergencies in international law
Authors: Dill Janina
Published: January 2023

Does international law restrict the use of force by states in self-defense even when their survival is threatened? Should it? To answer these questions, I compare international law to domestic law and develop two ideal-types of emergency: in a ‘subject emergency’ law imposes absolute, justiciable limits on self-defense. In a ‘community emergency’ the sovereign, not law, determines what is necessary for the survival of the community and its legal system: sustaining the rule of law justifies its temporary retreat. I show that international law has elements of both ideal-types. It imposes some absolute limits on self-defense. However, international law also retreats, allowing the victim state to determine the (1) aims, (2)ad bellumproportionality, and (3) end of self-defense, as if armed threats triggered community emergencies. These three retreats serve the function of sustaining the rule of international law over the states at war. Retreats (1) and (3) also help sustain the rule of international law over the international community. That international law does and shouldnottreat armed threats against states simply as subject emergencies, shows it can only sustain the rule of international law in an emergency by retreating. This is a negative litmus test for international law's ability to diffuse anarchy in International Relations.

Abstract: Although children use social and emotional learning skills (SEL) across the world, the expression of these skills may vary across cultures and developmental levels. Such variability complicates the process of assessing SEL competencies with consequences for understanding differences in SEL skills and developing interventions. To address these challenges, the current study examined the measurement invariance of translated versions of a brief, multi-informant (Teacher, Parent, Student) measure of SEL skills developed in the US with data from six European countries (Croatia, Greece, Italy, Latvia, Portugal, and Romania; n = 10,602; 8,520; 6,611, for the SSIS SEL b – Teacher, Parent, and Student versions, respectively). In addition to cross-country invariance testing, we conducted measurement invariance testing across ages (Primary and Secondary students) for the Teacher and Student forms of the measure. Results revealed a high degree of measurement invariance across countries (Scalar for the Teacher form and Partial Scalar for the Parent and Student form) and developmental levels (Scalar for the Teacher form and Partial Scalar for the Student form), supporting the use of translated versions of the SSIS SEL b for international research across these countries and developmental levels. Implications are discussed for assessment and promoting children’s SEL competencies globally.

Published: January 2023

Following on our earlier single‐station, 2‐dimensional (2D) broadband interferometric mapping and polarization (BIMAP) observations of lightning discharges, we recently deployed two BIMAP stations at Los Alamos National Laboratory to map the lightning sources and their polarization in full 3‐dimensional (3D) space (BIMAP‐3D). The two stations are separated by 11.5‐km and each station consists of four antenna sets (instead of three for the original BIMAP) that form a Y‐shaped array for improved interferometric performance. In this paper, we report the BIMAP‐3D system design, a generalized and analytical 2D interferometry technique for noncoplanar antenna array, a two‐stage 3D mapping technique based on geometric triangulation and baseline‐based differential time of arrival, and a technique to reconstruct the polarization orientation in 3D space by combining the 2D polarization results from the two‐station observations. Along with description of the techniques, we demonstrate and discuss the initial lightning results, including 3D maps for a hybrid intracloud and cloud‐to‐ground flash and for a normal intracloud flash, development of abnormal K‐change leaders, and polarization signatures for a K‐change leader. We find that with the two‐stage 3D mapping techniques, the sources can be located to meters accuracy for a favorable event that occurs between the two stations. We also find the polarization vectors for the example K leader are mostly orthogonal to the leader channel after the full 3D polarization analysis. The main purpose of this paper is to report the BIMAP‐3D techniques and capabilities. Detailed analysis of more specific discharge processes will be reported in later studies.
Emotional descriptions increase accidental harm punishment and its cortico-limbic signatures during moral judgment in autism

Published: January 2023

Individuals with autism spectrum disorder (ASD) present difficulties in integrating mental state information in complex moral tasks. Yet, ASD research has not examined whether this process is influenced by emotions, let alone while capturing its neural bases. We investigated how language-induced emotions modulate intent-based moral judgment in ASD. In a fMRI task, 30 adults with ASD and 27 neurotypical controls read vignettes whose protagonists commit harm either accidentally or intentionally, and then decided how much punishment the protagonist deserved. Emotional content was manipulated across scenarios through the use of graphic language (designed to trigger arousing negative responses) vs. plain (just-the-facts, emotionless) language. Off-line functional connectivity correlates of task performance were also analyzed. In ASD, emotional (graphic) descriptions amplified punishment ratings of accidental harms, associated with increased activity in fronto-temporo-limbic, precentral, and postcentral/supramarginal regions (critical for emotional and empathic processes), and reduced connectivity among the orbitofrontal cortex and the angular gyrus (involved in mentalizing). Language manipulation did not influence intentional harm processing in ASD. In conclusion, in arousing and ambiguous social situations that lack intentionality clues (i.e. graphic accidental harm scenarios), individuals with ASD would misuse their emotional responses as the main source of information to guide their moral decisions. Conversely, in face of explicit harmful intentions, they would be able to compensate their socioemotional alterations and assign punishment through non-emotional pathways. Despite limitations, such as the small sample size and low ecological validity of the task, results of the present study proved reliable and have relevant theoretical and translational implications.

Published: January 2023

This study aimed to explore the feasibility of the magnetic compression technique (MCT) for ureterovesical anastomosis in a rabbit model with ureteral obstruction. The distal ureteral obstruction model using female New Zealand rabbits was induced by ligating the distal end of the right ureter with silk thread for four weeks. A pair of cylindrical NdFeB magnets (daughter magnet and parent magnet) with a hole in the center was used for the ureterovesical anastomosis. The daughter magnet and the parent magnet were respectively placed close to the obstruction site through the dilated proximal ureter and urethra, and then the daughter-parent magnets pair was attracted together automatically. Postoperative X-rays were taken to confirm the position of the magnets. The anastomotic stoma specimens were obtained two weeks postoperatively, and the anastomotic stoma formation was observed by the naked eye and histological staining. The operation time and the anastomotic burst pressure were measured. The ureter was significantly dilated in the fourth week after ligation, which satisfied the placement of the daughter magnet. The ureterovesical magnet placements were successfully performed in ten experimental rabbits, with an operation time of 36.5 ± 6.09 min. The parent and daughter magnets attracted each other well and were subsequently removed through the urethra two weeks postoperatively, resulting in the establishment of ureterovesical anastomosis. The anastomotic burst pressure was 147.5 ± 14.59 mmHg. Gross specimens and histological examination of the anastomotic stoma showed that the anastomotic stoma healed well. MCT is feasible and simple for ureterovesical anastomosis.
Analysis of vocal communication in the genus Falco
Authors: Griffiths Carole S. , Aaronson Neil L.
Published: February 2023

Vocal learning occurs in three clades of birds: hummingbirds, parrots, and songbirds. Examining vocal communication within the Falconiformes (sister taxon to the parrot/songbird clade) may offer information in understanding the evolution of vocal learning. Falcons are considered non-vocal learners and variation in vocalization may only be the result of variation in anatomical structure, with size as the major factor. We measured syringes in seven Falco species in the collection at the American Museum of Natural History and compiled data on weight, wing length, and tail length. Audio recordings were downloaded from several libraries and the peak frequency and frequency slope per harmonic number, number of notes in each syllable, number of notes per second, duration of each note, and inter-note duration was measured. Mass, wing length, and syringeal measurements were strongly, positively correlated, and maximum frequency is strongly, negatively correlated with the size. Frequency slope also correlates with size, although not as strongly. Both note and inter-note length vary significantly among the seven species, and this variation is not correlated with size. Maximum frequency and frequency slope can be used to identify species, with the possibility that bird sounds could be used to identify species in the field in real time.
New failure mechanism for evaluating seismic and static undrained bearing capacity adjacent to 2D slope
Authors: Fang Hongwei , Xu Yixiang
Published: January 2023

The seismic or static undrained slip line field theory and Cauchy, Riemann, mixed boundary value problems for undrained soil slopes are derived. A new failure mechanism is proposed to determine the undrained bearing capacity adjacent to slopes. The effects of geometric or strength parameters and seismic forces on static and seismic undrained bearing capacity are investigated. The convergence of the proposed method is proved. The static and seismic undrained bearing capacities predicted by the proposed method are close to those of the currently existing methods. The proposed method does not need to assume or search the failure modes, and a new limit state evaluation index is given.

Published: January 2023

In Japan, mean birth weight has significantly decreased from 3152 g in 1979 to 3018 g in 2010 and the prevalence of preterm birth (PTB) has risen to 5.7% in the last thirty years. However, the presence and magnitude of geographical differences in low birthweight (LBW) and/or PTB in Japan is not well understood. We implemented spatial analysis to identify localized clusters and hot spots of LBW and/or PTB during 2012–2016. The Japan national birth database was used in this study. A total of 5,041,685 (male: 2,587,415, female: 2,454,270) births were used for spatial analysis using empirical Bayes estimates of the incidence rate of LBW and/or PTB and spatial scan tests to detect hot-spot areas with p values calculated from Monte Carlo iterations. The most and second likely clusters were located in two areas: (1) the small islands in south-west Japan (Amami and Okinawa, Relative risk = 1.09–1.67 with p < 0.001) and (2) the cities on the base of Mt. Fuji, stretching over three neighboring prefectures of Yamanashi, Shizuoka and Kanagawa (Relative risk = 1.10–1.55 with p < 0.001), respectively. We need to optimize the medical resource allocations based on the evidence in geographical clustering of LBW and/or PTB at specific locations in Japan.

Published: January 2023

2-Bromopropane (2-BP) is a colorless liquid at room temperature and is used in closed systems in factories, mainly as an intermediate for medicines, pesticides, and other chemicals. However, the carcinogenicity of 2-BP is still unknown. The CByB6F1-Tg(HRAS)2Jic (rasH2) transgenic mouse model has been established as an alternative to long-term studies (1.5 years—lifetime) to detect carcinogenicity in as short a time as six months. We performed a 26-week inhalation exposure study of 2-BP using the rasH2 mouse model. Male and female rasH2 mice were exposed to 0, 67, 200, or 600 ppm of 2-BP for 6 h/day, 5 days/week for 26 weeks. All tissues and blood were collected and subjected to biological and histopathological analyses. The results showed a concentration-dependent increase in lung tumor development in male and female rasH2 mice exposed by inhalation to 2-BP, which was significant by Peto’s and Poly-3 trend tests. Furthermore, in male rasH2 mice, 2-BP was found to be a testicular toxin. This study is the first to demonstrate that 2-BP is carcinogenic in male and female mice and a testicular toxin in male mice using the rasH2 mouse model.
Handgrip strength in older adults from Antioquia-Colombia and comparison of cutoff points for dynapenia
Authors: Patiño-Villada Fredy Alonso , Estrada-Restrepo Alejandro , Aristizábal Juan
Published: January 2023

Handgrip strength is a predictor of functional impairment and presence of morbimortality in older adults. However, appropriate reference values and cutoff points are required for its optimal use. This study describes handgrip characteristics in the older adult population of Antioquia-Colombia and compares the dynapenia handgrip cutoffs proposed for Colombians with international criteria. A cross-sectional study including 1592 older adults was done. Dynapenia prevalence by handgrip was analyzed using the following cutoffs: European Consensus of Sarcopenia (2018), Asian Working Group for Sarcopenia (2019), Chilean (2018), and Colombian (2019). Handgrip strength significantly decreased with aging, showing a positive and strong association with functional and health parameters. The highest prevalence of dynapenia was found with the Asian Consensus cutoffs (26.1%) and the lowest with the Colombian cutoffs (0.8%). Low agreement was found between the Colombian cutoffs with the European Consensus (kappa = 0.059; p < 0.001), the Asian Consensus (kappa = 0.039; p < 0.001) and the Chilean proposal (kappa = 0.053; p < 0.001). Dynapenia using the Chilean, European, and Asian cutoffs was associated with physical inactivity, presence of multimorbidity, slow gait speed, nutritional risk, and low calf circumference. Meanwhile, the Colombian cutoffs was only associated with slow gait speed and low calf circumference. The handgrip cutoffs proposed for Colombians seems to underestimate the dynapenia prevalence in older people from Antioquia. Furthermore, these cutoff points did not show associations with relevant functional and health parameters. The handgrip cutoffs proposed for Colombians should be used with caution.

Authors: Zhang Ruiping , Zhang Bo , Fu Shixiang
Published: January 2023

Based on the theory of equal base circle bevel gears, a new type of gear, the equal base circle herringbone curved bevel gear, is studied further to reduce the axial force problem of curved bevel gears. Using the principle of equal basis circle herringbone curved bevel gear as a basis, the tooth trace and the tool design of this gear were studied. Based on the principle of space meshing, the process of finger milling cutter enveloping machining gear was analyzed, and a tooth surface equation was calculated; This paper proposes two modeling methods: tooth trace modeling and tooth surface modeling. The gear model is consistent through the analysis and comparison of the two modeling methods. The axial force of the gear contact between the equal base circle herringbone curved bevel gear and Gleason are analyzed and compared, which verified the proper reduction of axial force.
Early warm compress treatment can promote recanalization of vascular embolisms and reduce tissue necrosis after polymethyl methacrylate injection

Published: February 2023

Injection of fillers for soft tissue augmentation can lead to a variety of complications, among which vascular occlusion caused by intravascular injection of filler will induce severe or permanent damage. The treatment strategies for intravascular embolization caused by injection include warm compress application, but the exact beneficial effects of this therapy have not been confirmed. The purpose of this study is to construct an intravascular injection embolism model and observe the effectiveness of warm and cold compress through a randomized, controlled trial. Thirty rabbit’s sixty ears were randomly divided into warm compress group, cold compress group, and control group. Polymethyl methacrylate (PMMA) was slowly injected into the central ear artery (CEA) to cause vascular embolism. Warm compress and cold compress treatment were performed respectively. The vascular recanalization and other related indexes were observed at 30 min, 1 day, and 7 days after injection, and the tissue necrosis was analyzed at 7 days. In the early stage of vascular embolization, warm compress can immediately promote vascular dilatation, blood circulation and partial blood flow recovery. One day after intravascular injection, warm compress can reduce intravascular embolization and reduce the incidence of tissue necrosis. At 7 days after intravascular injection, the vessels in the cold compress and control groups were still embolized while the percentage of recanalization in the warm compress group was 47.4% (P < 0.000). Early-stage warm compress after intravascular PMMA injection is conducive to recanalization of vascular embolization and reducing tissue necrosis.
TRPM8 thermosensation in poikilotherms mediates both skin colour and locomotor performance responses to cold temperature
Authors: Malik Hannan R. , Bertolesi Gabriel E. , McFarlane Sarah
Published: January 2023

Thermoregulation is a homeostatic process to maintain an organism’s internal temperature within a physiological range compatible with life. In poikilotherms, body temperature fluctuates with that of the environment, with both physiological and behavioral responses employed to modify body temperature. Changing skin colour/reflectance and locomotor activity are both well-recognized temperature regulatory mechanisms, but little is known of the participating thermosensor/s. We find that Xenopus laevis tadpoles put in the cold exhibit a temperature-dependent, systemic, and rapid melanosome aggregation in melanophores, which lightens the skin. Cooling also induces a reduction in the locomotor performance. To identify the cold-sensor, we focus on transient receptor potential (trp) channel genes from a Trpm family. mRNAs for several Trpms are present in Xenopus tails, and Trpm8 protein is present in skin melanophores. Temperature-induced melanosome aggregation is mimicked by the Trpm8 agonist menthol (WS12) and blocked by a Trpm8 antagonist. The degree of skin lightening induced by cooling is correlated with locomotor performance, and both responses are rapidly regulated in a dose-dependent and correlated manner by the WS12 Trpm8 agonist. We propose that TRPM8 serves as a cool thermosensor in poikilotherms that helps coordinate skin lightening and behavioural locomotor performance as adaptive thermoregulatory responses to cold.
A vein wall cell atlas of murine venous thrombosis determined by single-cell RNA sequencing

Published: January 2023

Deep vein thrombosis (DVT) is a common clinical problem, but its cellular and molecular mechanisms remain incompletely understood. In this study, we performed single-cell RNA sequencing on mouse inferior vena cava (IVC) 24 h after thrombus-inducing IVC ligation or sham operation. 9 cell types composed of multiple subpopulations were identified. Notable transcriptomic changes induced by DVT included a marked inflammatory response, elevated hypoxia, and globally reduced myogenesis. Analysis of individual cell populations revealed increased inflammation and reduced extracellular matrix production across smooth muscle cells and fibroblasts, juxtaposed against an early phenotypic shift in smooth muscle cell populations away from a contractile state. By characterizing the transcriptomic changes in the vein wall during acute venous thrombosis at the single-cell level, this work provides novel insights into early pathological events in the vein wall that may potentiate thrombus formation and result in long term adverse venous remodeling.

Published: January 2023

We present the chemical composition of 206 red giant branch stars that are members of the Small Magellanic Cloud (SMC) using optical high-resolution spectra collected with the multi-object spectrograph FLAMES-GIRAFFE at the ESO Very Large Telescope. This sample includes stars in three fields that are located in different positions within the parent galaxy. We analysed the main groups of elements, namely light- (Na), α- (O, Mg, Si, Ca, and Ti), iron-peak (Sc, V, Fe, Ni, and Cu), and s-process elements (Zr, Ba, and La). The metallicity distribution of the sample displays a main peak around [Fe/H]∼–1 dex and a weak metal-poor tail. However, the three fields display different [Fe/H] distributions. In particular, a difference of 0.2 dex is found between the mean metallicities of the two innermost fields. The fraction of metal-poor stars increases significantly (from ∼1 to ∼20%) from the innermost fields to the outermost field, likely reflecting an age gradient in the SMC. We also found an indication of possible chemically and kinematic distinct substructures. The ratios of the SMC stars are clearly distinct from those of Milky Way stars, in particular, for the elements produced by massive stars (e.g. Na, α, and most iron-peak elements), whose abundance ratios are systematically lower than those measured in our Galaxy. This shows that massive stars contributed less to the chemical enrichment of the SMC than the Milky Way, according to the low star formation rate expected for this galaxy. Finally, we identified small systematic differences in the abundances of some elements (Na, Ti, V, and Zr) in the two innermost fields, suggesting that the chemical enrichment history in the SMC has not been uniform.

Digital Rocks Portal (DRP, https://www.digitalrocksportal.org) organizes and preserves imaged datasets and experimental measurements of porous materials in subsurface, and beyond, with the mission to connect them to simulation and analysis, as well as educate the research community. We have over 150 projects represented in more than 200 publications, and an active community that reuses the data, most recently in multiple machine learning applications for automating image analysis as well as the prediction of transport. Such automation is crucial for performing formation evaluation tasks in near-real time. We present benchmark datasets that have played a role in recent machine learning prediction successes in the field. We further discuss the vision for further research advances, educational materials, as well as growth and sustainability plan of this digital rock physics community resource. In particular, we are in the process of expanding into a broader repository of engineered porous materials, specifically those for energy storage and the portal will transition to Digital Porous Media (DPM) in near future.
Some Useful Guidelines for Whole Core CT-Scanning for Petrophysical Applications
Authors: Siddiqui Shameem
Published: January 2023

From the time CT-scanning was introduced in the oil and gas industry, its use could be divided into SCAL and routine type applications. The first involves flowing fluids through the cores, whereas the second involves scanning, mainly the whole cores, in their native (preserved or unpreserved) state. For whole core CT-scanning, there has been a constant shift from qualitative to quantitative analysis. The size of whole cores is ideal for scanning them with a ‘converted’ medical CT-scanner but obtaining meaningful data requires more than just artifact-free images. In this paper, useful guidelines are offered for extracting meaningful quantitative data from whole core CT-scanning. Today’s fast, multi-slice medical CT-scanners generally provide sufficient image resolution for most of the whole core related applications. However, they usually require some modifications to the equipment and the calibration procedures. Special solid phantoms matching the size and density should be used for calibrating the scanner at different X-ray energies. A set of calibration ‘standards’ is necessary for converting the CT numbers into density and Zeff (Effective Atomic numbers), which should be scanned under the similar ‘environment’ as the whole cores. Using pilot scans is highly recommended for every core tube to reduce uncertainties. For dual energy scanning, it is important to take scans at the exact same locations, selecting the right energy pair and corresponding calibration tables. For image processing, important guidelines include aligning the first and last slices for selecting the largest region-of-interest, quality controlling each slice and assigning depths to each slice before converting from CT numbers to bulk density and Zeff. Additional information is provided for scanning with industrial CT-scanners which have both advantages and disadvantages. Guidelines such as the ones mentioned above allow the data from whole core CT imaging useful for a number of applications. Such data were successfully used for bulk density and porosity determination, heterogeneity quantification, lithology determination, dual-energy based mineralogy detection, density-based micro-imaging, core-log correlations and depth matching, fracture characterization, formation damage evaluation, and many others. Several examples are included in this paper. Adherence to strict guidelines helps extracting artifact-free, meaningful data on whole cores that can improve our understanding of rocks. This paper demonstrates at least 10 different applications of CT-scanners along with the proper guidelines that can be useful for engineers and geoscientists.
Psychopharmaka sind kein Allheilmittel
Authors: Dißmann Steffen
Published: January 2023

Der Einsatz von Psychopharmaka in der Psychiatrie ist seit vielen Jahren ein etabliertes therapeutisches Mittel, um schwere psychische Ausnahmezustände zu stabilisieren. Während das eine Lager eben jenen Effekt befürwortet, verurteilt das andere den Gebrauch von Psychopharmaka vehement. Wird der Griff zur Medikamentenpackung bei Kindern und Jugendlichen empfohlen, um ein funktionierendes Mitglied unserer Leistungsgesellschaft zu werden, erhält das Thema eine zusätzliche ethische Brisanz. Denn neben der erwünschten Verhaltensänderung bzw. Abmilderung der Symptomatik wirken sich psychoaktive Medikamente auch häufig auf das Wesen des Kindes oder Jugendlichen aus.
Cytotoxicity of Carvotacetones from Sphaeranthus africanus Against Cancer Cells and Their Potential to Induce Apoptosis

Published: January 2023

Three carvotacetones (1 – 3) isolated from Sphaeranthus africanus were screened in 60 cancer cell lines at the National Cancer Institute (NCI) within the Developmental
Therapeutics Program (DTP). At the concentration of 10−5 M, compound 1 (3,5-diangeloyloxy-7-hydroxycarvotacetone) turned out to be the most active compound against ACHN and
UO-31 renal cancer cell lines with growth percent values of − 100% (all cells dead). Compound 2 (3-angeloyloxy-5-[2″,3″-epoxy-2″-methylbutanoyloxy]-7-hydroxycarvotacetone) showed
strong effects in SK-MEL-5 melanoma and ACHN renal cancer cells with inhibition values of 93% and 97%, respectively. Compound 3
(3-angeloyloxy-5-[3″-chloro-2″-hydroxy-2″-methylbutanoyloxy]-7-hydroxy-carvotacetone) exhibited a quite strong effect on renal cancer cells with a growth inhibitory effect of 96% against
ACHN and UO-31 cells. When treated with five different concentrations of 1 (1 × 10−8, 1 × 10−7, 1 × 10−6, 1 × 10−5, and
1 × 10−4 M), HOP-92 cells were found to be most sensitive with GI50, TGI, and LC50 values of 0.17, 0.40, and 0.96 µM, respectively. When using the ApoTox-Glo
triplex assay to evaluate the apoptosis inducing effects of seven carvotacetones isolated from S. africanus in CCRF-CEM cells, compounds 1 – 6 increased caspase-3/7
activity with 1, 2, and 4 (3-angeloyloxy-5,7-dihydroxycarvotacetone) exhibiting the highest activitiy, indicating induction of caspase-dependent apoptosis.

Magnetic skyrmions in FePt square-based nanoparticles around room-temperature
Authors: Tyrpenou Christos , Stavrou Vasileios D , Gergidis Leonidas N
Published: January 2023

Magnetic skyrmions formed at temperatures around room temperature in square-based parallelepiped magnetic FePt nanoparticles with perpendicular magnetocrystalline anisotropy (MCA) were studied during the magnetization reversal process using micromagnetic simulations. Finite differences method were used for the solution of the Landau–Lifshitz–Gilbert equation. Magnetic configurations exhibiting Néel skyrmionic formations were detected. The magnetic skyrmions can be created in different systems by the variation of external field, side length and width of the squared-based parallelepiped magnetic nanoparticles. Micromagnetic configurations revealed a variety of states which include skyrmionic textures with one distinct skyrmion formed and stabilized for a range of external fields around room-temperature. The size of the nucleated Néel skyrmion is calculated as a function of the external field, temperature, MCA and nanoparticle’s geometrical characteristic lengths which can be adjusted to produce skyrmions on demand having diameters down to 12 nm. The micromagnetic simulations revealed that stable skyrmions in the temperature range of 270–330 K can be created for FePt magnetic nanoparticle systems lacking of chiral interactions such as Dzyaloshinskii–Moriya.
Enhanced generalized nonlinear sparse spectrum based on dual-tree complex wavelet packet transform for bearing fault diagnosis
Authors: Yang Zujie , Zhang Zongzhen , Wang Jinrui , Han Baokun , Liu Zongling , Ma Hao , Xing Shuo
Published: January 2023

The generalized nonlinear sparse spectrum (GNSS), as an improved fast kurtogram (FK) method, effectively suppresses the interference of abnormal signals through nonlinear preprocessing and sparse enhancement. However, the GNSS method inherits the shortcoming of the traditional FK method, using finite impulse response filters to process nonstationary signals, which limits the accuracy of fault extraction. Therefore, more precise filters should be developed to further improve the performance of fault features. Inspired by this, this paper introduces the dual-tree complex wavelet packet transform (DTCWPT) into the sparse spectrum, and proposes an enhanced generalized nonlinear sparse spectrum (EGNSS) for bearing fault diagnosis. Firstly, nonlinear preprocessing is performed on the input signal to weaken the interference of abnormal impacts. Secondly, the generalized pq-mean value of each subband obtained by DTCWPT is calculated. Finally, the sparse spectrum is constructed and the signal reconstruction is performed on the frequency band where the maximum generalized pq-mean value is located for the envelope analysis. Simulation signals and experimental bearing fault signals have been applied to demonstrate the superiority of the proposed EGNSS in improving fault performance and accuracy.
Recent advances and perspectives in GNSS PPP-RTK

Published: January 2023

Precise point positioning-real-time kinematic (PPP-RTK), otherwise known as integer ambiguity resolution-enabled precise pointing positioning, has attracted much attention in recent years and has become state-of-the-art in the global navigation satellite system (GNSS) high-precision positioning community. This work reviews several PPP-RTK methods, outlines a set of PPP-RTK applications, and presents possible future developments. According to the parameterization considered, we clarify the PPP-RTK models into a distinct-clock category and two common-clock categories (common-clock-1 and common-clock-2), in which several ionosphere-free PPP-RTK models can be cast. Compared with the ionosphere-free PPP-RTK model, we emphasize the advantages of the undifferenced and uncombined (UDUC) formulation and recommend the common-clock-1 UDUC PPP-RTK model since it is optimal, flexible, and widely applicable. Based on what kinds of parameters can be estimated by PPP-RTK models, we outline the PPP-RTK applications in several aspects, including position-based applications, time transfer, atmospheric retrieval, and GNSS bias estimation. Despite the huge advances in GNSS PPP-RTK, future research should improve PPP-RTK performances in harsh environments and apply PPP-RTK to mass markets.
