AbstractRubus (Rosaceae), one of the most complicated angiosperm genera, contains about 863 species, and is notorious for its taxonomic difficulty. The most recent (1910–1914) global taxonomic treatment of the genus was conducted by Focke, who defined 12 subgenera. Phylogenetic results over the past 25 years suggest that Focke's subdivisions of Rubus are not monophyletic, and large‐scale taxonomic revisions are necessary. Our objective was to provide a comprehensive phylogenetic analysis of the genus based on an integrative evidence approach. Morphological characters, obtained from our own investigation of living plants and examination of herbarium specimens are combined with chloroplast genomic data. Our dataset comprised 196 accessions representing 145 Rubus species (including cultivars and hybrids) and all of Focke's subgenera, including 60 endemic Chinese species. Maximum likelihood analyses inferred phylogenetic relationships. Our analyses concur with previous molecular studies, but with modifications. Our data strongly support the reclassification of several subgenera within Rubus. Our molecular analyses agree with others that only R. subg. Anoplobatus forms a monophyletic group. Other subgenera are para‐ or polyphyletic. We suggest a revised subgeneric framework to accommodate monophyletic groups. Character evolution is reconstructed, and diagnostic morphological characters for different clades are identified and discussed. Based on morphological and molecular evidence, we propose a new classification system with 10 subgenera: R. subg. Anoplobatus, R. subg. Batothamnus, R. subg. Chamaerubus, R. subg. Cylactis, R. subg. Dalibarda, R. subg. Idaeobatus, R. subg. Lineati, R. subg. Malachobatus, R. subg. Melanobatus, and R. subg. Rubus. The revised infrageneric nomenclature inferred from our analyses is provided along with synonymy and type citations. Our new taxonomic backbone is the first systematic and complete global revision of Rubus since Focke's treatment. It offers new insights into deep phylogenetic relationships of Rubus and has important theoretical and practical significance for the development and utilization of these important agronomic crops.

Published: March 2023

ABSTRACTBackgroundAutomated fluorescence‐based haematology analysers are now available for reticulocyte enumeration in veterinary medicine, but manual counting is still largely used. This study aimed to evaluate potential sources of analytical and pre‐analytical errors when performing automated and manual counts.MethodsAutomated and two‐operator double‐blind manual reticulocyte counts were performed on 15 blood samples. The intra‐assay variation of the automated and manual counts and the interoperator variation in the manual counts were then calculated. In addition, the effects of storage were evaluated using samples refrigerated at 4°C or stored at room temperature for 2, 4, 12, 24, 48 or 72 hours after sampling.ResultsIntra‐assay coefficients of variation were lower for automated counts than for manual counts. Comparison between automated and mean total manual reticulocyte count showed no significant differences. In both refrigerated samples and those stored at room temperature, an increase in reticulocyte count was recorded only after 72 hours. Staining artefacts occurred only in one stored sample counted manually.LimitationsThe presence of cytoplasmic particles other than RNA can cause misinterpretation of cells, leading to an erroneous reticulocyte count.ConclusionThe use of an automated analyser is preferable for reticulocyte enumeration in dogs. Common storage conditions seem to minimally affect reticulocyte evaluation; however, it is recommended to perform the analysis as soon as possible after sampling.
Teacher Education in the Nordic Remake: How Transnational Policymaking Transforms Regional Collaboration
Authors: Krejsler John Benedicto 
Published: March 2023

AbstractSince the 1990s, teacher education policies and programmes in Nordic countries have been increasingly shaped by their profound involvement in international and transnational collaborations. Today, the OECD’s PISA and the IEA’s Progress in Reading Literacy Study (PIRLS) and Trends in Mathematics and Science Study (TIMSS) define how European national school policy is talked about and organized, and the Bologna Process has become pivotal for how teacher education is thought about and organized. Thus, Nordic collaboration has largely been transformed in the sense that Nordic countries gain perspective in transnational collaborations by comparing their performances with those of other Nordic countries and adapting the agendas for Nordic collaborations to larger international and transnational agendas.This chapter demonstrates how teacher education in the Nordic countries has been reshaped by these developments in three key areas: (1) the impact of the transnational turn in education policy, in particular the Bologna Process; (2) how this turn has been driven by increasing primacy of Anglo-American educational norms (evidence, standards-based education, coupling the market with education, etc.); and (3) the impact of the transnational turn in school policy reform on the framing of teacher education in both discourse and practice.
Efficient Continuous Latency Monitoring with eBPF

Published: March 2023

AbstractNetwork latency is a critical factor for the perceived quality of experience for many applications. With an increasing focus on interactive and real-time applications, which require reliable and low latency, the ability to continuously and efficiently monitor latency is becoming more important than ever. Always-on passive monitoring of latency can provide continuous latency metrics without injecting any traffic into the network. However, software-based monitoring tools often struggle to keep up with traffic as packet rates increase, especially on contemporary multi-Gbps interfaces. We investigate the feasibility of using eBPF to enable efficient passive network latency monitoring by implementing an evolved Passive Ping (ePPing). Our evaluation shows that ePPing delivers accurate RTT measurements and can handle over 1 Mpps, or correspondingly over 10 Gbps, on a single core, greatly improving on state-of-the-art software based solutions, such as PPing.

Financial production and the subprime mortgage crisis
Authors: Tori Daniele , Caverzasi Eugenio , Gallegati Mauro 
Published: March 2023

AbstractThe causes of the 2007-8 subprime crisis continue to be the subject of much debate, with explanations ranging from de-regulation and fraudulent behavior to global imbalances and rising inequality. However, a comprehensive analysis of the endogenous forces that made the crisis inevitable has yet to be presented. This paper offers a ‘structural’ interpretation of the crisis by synthesising insights from conventional financial economics and the Minskyian and Schumpeterian literature. While highlighting the innovative character of US financial firms evolving from credit providers to producers of financial commodities, we stress the key features of their path towards financial fragility. We contend that financial institutions were able to achieve progressively unsustainable positions due to the ‘enforced indebtedness’ of US households, which played a functional, albeit secondary, role in the development of the crisis.
The bifurcation and topography of the posterior tibial artery within the tarsal tunnel
Authors: Marchese B. , McDonald A. , McGowan H. 
Published: March 2023

Abstract
Purpose
The tarsal tunnel (TT) is a fibro-osseous anatomical space coursing from the medial ankle to the medial midfoot. This tunnel acts as a passage for both tendinous and neurovascular structures, including the neurovascular bundle containing the posterior tibial artery (PTA), posterior tibial veins (PTVs) and tibial nerve (TN). Tarsal tunnel syndrome (TTS) is the entrapment neuropathy that describes the compression and irritation of the TN within this space. Iatrogenic injury to the PTA plays a significant role in both the onset and exacerbation of TTS symptoms. The current study aims to produce a method to allow clinicians and surgeons to easily and accurately predict the bifurcation of the PTA, to avoid iatrogenic injury during treatment of TTS.

Methods
Fifteen embalmed cadaveric lower limbs were dissected at the medial ankle region to expose the TT. Various measurements regarding the location of the PTA within the TT were recorded and multiple linear regression analysis performed using RStudio.

Results
Analysis provided a clear correlation (p < 0.05) between the length of the foot (MH), length of hind-foot (MC) and location of bifurcation of the PTA (MB). Using these measurements, this study developed an equation (MB = 0.3*MH + 0.37*MC – 28.24 mm) to predict the location of bifurcation of the PTA within a 23° arc inferior to the medial malleolus.

Conclusions
This study successfully developed a method whereby clinicians and surgeons can easily and accurately predict the bifurcation of the PTA, to avoid iatrogenic injury that would previously lead to an exacerbation of TTS symptoms.
Computational aspects of experimental designs in multiple-group mixed models
Authors: Prus Maryna , Filová Lenka 
Published: March 2023

AbstractWe extend the equivariance and invariance conditions for construction of optimal designs to multiple-group mixed models and, hence, derive the support of optimal designs for first- and second-order models on a symmetric square. Moreover, we provide a tool for computation of D- and L-efficient exact designs in multiple-group mixed models by adapting the algorithm of Harman et al. (Appl Stoch Models Bus Ind, 32:3–17, 2016). We show that this algorithm can be used both for size-constrained problems and also in settings that require multiple resource constraints on the design, such as cost constraints or marginal constraints.
Sum Index, Difference Index and Exclusive Sum Number of Graphs
Authors: Haslegrave John 
Published: March 2023

AbstractWe consider two recent conjectures made by Harrington, Henninger-Voss, Karhadkar, Robinson and Wong concerning relationships between the sum index, difference index and exclusive sum number of graphs. One conjecture posits an exact relationship between the first two invariants; we show that in fact the predicted value may be arbitrarily far from the truth in either direction. In the process we establish some new bounds on both the sum and difference index. The other conjecture, that the exclusive sum number can exceed the sum index by an arbitrarily large amount, follows from known, but non-constructive, results; we give an explicit construction demonstrating it. Simultaneously with the first preprint of this paper appearing, Harrington et al. updated their preprint with two counterexamples to the first conjecture; however, their counterexamples only give a discrepancy of 1, and only in one direction. They therefore modified the conjecture from an equality to an inequality; our results show that this is still false in general.
Grounding the Selectionist Explanation for the Success of Science in the External Physical World
Authors: van der Merwe Ragnar 
Published: March 2023

AbstractI identify two versions of the scientific anti-realist’s selectionist explanation for the success of science: Bas van Fraassen’s original and K. Brad Wray’s newer interpretation. In Wray’s version, psycho-social factors internal to the scientific community – viz. scientists’ interests, goals, and preferences – explain the theory-selection practices that explain theory-success. I argue that, if Wray’s version were correct, then science should resemble art. In art, the artwork-selection practices that explain artwork-success appear faddish. They are prone to radical change over time. Theory-selection practices that explain theory-success in science are however not faddish. They are mostly stable; that is, long-lived and consistent over time. This is because scientists (explicitly or implicitly) subscribe to what I will call the testability norm: scientific theories must make falsifiable claims about the external physical world. The testability norm and not psycho-sociology explains the theory-selection practices that explain theory-success in science. Contra Wray, scientific anti-realists can then maintain that the external physical world (as expressed in the testability norm) explains theory-success.

Sliding modes of high codimension in piecewise-smooth dynamical systems
Authors: Guglielmi Nicola , Hairer Ernst 
Published: March 2023

AbstractWe consider piecewise-smooth dynamical systems, i.e., systems of ordinary differential equations switching between different sets of equations on distinct domains, separated by hyper-surfaces. As is well-known, when the solution approaches a discontinuity manifold, a classical solution may cease to exist. For this reason, starting with the pioneering work of Filippov, a concept of weak solution (also known as sliding mode) has been introduced and studied. Nowadays, the solution of piecewise-smooth dynamical systems in and close to discontinuity manifolds is well understood, if the manifold consists locally of a single discontinuity hyper-surface or of the intersection of two discontinuity hyper-surfaces. The present work presents partial results on the solution in and close to discontinuity manifolds of codimension 3 and higher.
What are you reading? From core journals to trendy journals in the Library and Information Science (LIS) field
Authors: Safón Vicente , Docampo Domingo 
Published: March 2023

AbstractIn this study, we present an objective, replicable methodology to identify trendy journals in any consolidated discipline. Trendy journals are those most read by authors who are currently publishing within the scope of the discipline. Trendy journal lists differ from consolidated lists of top core journals; the latter are very stable over time, mainly reflecting reputational factors, whereas the former reveal current influences not yet captured by studies based on bibliometric indicators or expert surveys. We apply our methodology to identify trendy journals among 167 titles indexed in the Web of Science category of the Information Science & Library Science (LIS) research area. Our list of trendy journals represents the most influential journals nowadays in the LIS discipline, challenging to some extent the core LIS journal list and journal category lists ordered by citations (e.g., by the Journal Impact Factor). Our results show that Scientometrics is the journal that bears the most influence on current production when not corrected for journal size and that Quantitative Science Studies—a small, relatively new journal not yet assigned a Journal Impact Factor nor present on any list of core LIS journals—is the journal that has shown the most significant recent influence when controlling for size.
Ecohydrogeochemistry of the Slikken van Flakkee, a former tidal wetland in the Netherlands

Published: March 2023

Abstract
The Slikken van Flakkee, a former tidal wetland in the Grevelingen, the Netherlands, has been changing under freshening conditions since 1971; in that year, the salty Grevelingen estuary was closed from the North Sea as part of the Dutch Delta Works. Our research aimed to analyse vegetation development over 1972–2016 and relates succession to quantified ecohydrogeochemical processes in the Slikken van Flakkee. We analysed succession and physico-chemical conditions at 63 monitoring locations. Based on extensive fieldwork in 2016 and 2017, we quantified the identified geochemical processes via inverse modelling and applied Canonical Correspondence Analysis (CCA) to search for interrelations with vegetation. Nine per cent of the 229 observed plant species are rare and threatened or vulnerable, according to the Dutch Red List. Succession series showed a development from saline pioneer communities towards grassland and shrub vegetation dependent on management measures (grazing and mowing versus spontaneous development), desalinisation and geochemical processes, of which dissolution of carbonates appeared to be the dominant one. During desalinisation, the water-type shifted from NaCl towards CaHCO3. The CCA confirmed the impact of geochemical and texture variables, elevation and management on vegetation. Grazing and mowing led to species-rich grasslands and forb vegetation harbouring twice as many species than the spontaneously developed area after 50 years, demonstrating the importance of active nature management. We argue that hydrological-geochemical modelling is necessary to support policy-making before deciding on the partial re-establishment of the tide in Lake Grevelingen.
Anti-inflammatory maistemonine-class alkaloids of Stemona japonica
Authors: Tan Cheng -Yong , Shi Bao-Bao , Bao Mei-Fen , Cai Xiang-Hai 
Published: March 2023

AbstractThree hitherto undescribed Stemona alkaloids, named stemajapines A–C (1–3), along with six known alkaloids (4–9), were isolated and identified from the roots of Stemona japonica (Blume) Miq. (Stemonaceae). Their structures were established by the analysis of the mass data, NMR spectra, and computational chemistry. Stemjapines A and B were degraded maistemonines without spiro-lactone ring and skeletal methyl from maistemonine. Concurrence of alkaloids 1 and 2 revealed an undescribed way to form diverse Stemona alkaloids. Bioassay results disclosed the anti-inflammatory natural constituents stemjapines A and C with IC50 values of 19.7 and 13.8 µM, respectively, compared to positive control dexamethasone with 11.7 µM. The findings may point out a new direction of Stemona alkaloids inaddition to its traditional antitussive and insecticide activities.
Are German National Accounts informationally efficient?
Authors: Döhrn Roland 
Published: March 2023

AbstractNational accounts are subject to major revisions. To improve the reliability of first release data, it is important to know whether subsequent revisions show systematic patterns. Or, in other words, whether national accounts are informationally efficient in the sense that all available information is incorporated into the data. This paper used annual data to test three dimensions of informational efficiency: weak efficiency, strong efficiency, and Nordhaus efficiency. The weak efficiency tests found GDP revisions to be noise, whereas revisions of several GDP components showed systematic patterns. Strong efficiency tests found covariations of GDP revisions with some indicators. Business survey results in particular have the potential to reduce the extent of revisions. Finally, Nordhaus efficiency tests found some indication of revision stickiness.
Experiences of Users with an Online Self-Guided Mental Health Training Program Using Gamification

Published: March 2023

AbstractYoung adulthood is a period of high risk for the development of mental health concerns. Increasing well-being among young adults is important to prevent mental health concerns and their consequences. Self-compassion has been identified as a modifiable trait with the potential to protect against mental health concerns. An online self-guided mental health training program using gamification was developed and the user experience was evaluated in a 6-week experimental design. During this period, 294 participants were allocated to use the online training program via a website. User experience was assessed via self-report questionnaires, and interaction data for the training program were also collected. Results showed that those who completed the intervention (n= 47) visited the website on average 3.2 days a week, with a mean of 45.8 interactions during the 6 weeks. Participants report positive user experiences of the online training, on average a System Usability Scale Brooke (1) score of 79.1 (out of 100) at the end-point. Participants showed positive engagement with story elements of the training, based on an average score of 4.1 (out of 5) in the evaluation of the story at the end-point. This study found the online self-compassion intervention for youth to be acceptable, although some features seem preferred by users as compared to others. Gamification in the form of a guiding story and a reward structure seemed to be a promising element for successfully motivating participants and serving as a guiding metaphor for self-compassion.
Optimal stable Ornstein–Uhlenbeck regression
Authors: Masuda Hiroki 
Published: March 2023

AbstractWe prove asymptotically efficient inference results concerning an Ornstein–Uhlenbeck regression model driven by a non-Gaussian stable Lévy process, where the output process is observed at high frequency over a fixed period. The local asymptotics of non-ergodic type for the likelihood function is presented, followed by a way to construct an asymptotically efficient estimator through a suboptimal, yet very simple preliminary estimator.
