description: Η παρούσα εργασία έχει ως αντικείμενο τη μελέτη των πληθυσμών του είδους Eunice aphroditois στην περιοχή του Διαύλου των Ωρεών, όπου και παρατηρείται σημαντική αλίευσή του. Η ανάπτυξη των πληθυσμών αυτών επηρεάζεται από διάφορους αβιοτικούς παράγοντες, όπως ο έντονος υδροδυναμισμός της περιοχής, αλλά και ανθρωπογενείς δραστηριότητες, όπως η αλίευση, οι κατασκευές λιμενικών έργων και ο τουρισμός. Το είδος Eunice aphroditois είναι το μεγαλύτερο σε μήκος από τα 8 καταγεγραμμένα στην Ελλάδα είδη του γένους Eunice, με μέγεθος ικανοποιητικό για τους πληθυσμούς που μελετήθηκαν. Στα χαρακτηριστικά του είδους περιλαμβάνονται ο φυλετικός διμορφισμός (διαφορετικός χρωματισμός φύλων) και οι συχνές αναπλάσεις του σώματος του με αυτοτομή, ενώ δεν εμφανίζει μεγάλης διάρκειας προνυμφικό στάδιο. Η διάμετρος των αυγών μετρήθηκε μέσα στα καταγεγραμμένα όρια των συγγενικών ειδών της οικογένειας. Σπουδαίο ρόλο παίζει η συμπεριφορά φωλεόποίησης του είδους στη δημιουργία στοών στο υπόστρωμα, γεγονός που επιδρά σημαντικά στη δομή και λειτουργία των μαλακών υποστρωμάτων. Στην εργασία περιγράφονται διεξοδικά τα στάδια εντοπισμού, σύλληψης και διατήρησης των δειγμάτων, ενώ πραγματοποιήθηκαν και οι απαραίτητες στατιστικές και βιομετρικές αναλύσεις. Η εκτίμηση της κατανομής της σχετικής αφθονίας, σε ό,τι αφορά το συντελεστή της αλιευτικής απόδοσης, δεν έδειξε σημαντικές διαφοροποιήσεις από περιοχή σε περιοχή, ενώ, αντίθετα, διαφοροποιήσεις σε στάθμη σημαντικότητας 90% έχουν παρουσιαστεί μεταξύ των σταθμών του βόρειου τμήματος της Εύβοιας και εκείνων της Στερεάς Ελλάδας. Οι βιομετρικές αναλύσεις που πραγματοποιήθηκαν έδειξαν ότι το μέσο μέγεθος των ατόμων βρίσκεται κάτω από τη μέση τιμή του ανώτερου μήκους που έχει καταγραφεί μέχρι σήμερα. Επίσης, οι βέλτιστες συσχετίσεις παρατηρήθηκαν μεταξύ του μήκους και του βάρους, του μήκους και του αριθμού των μεταμερών, του βάρους και του αριθμού των μεταμερών και, τέλος, μεταξύ του μήκους και του όγκου. Τα αποτελέσματα της έρευνας υπογραμμίζουν το ρόλο του είδους ως οικολογική λειτουργική μονάδα μέσα στο οικοσύστημα και ορίζουν ως επιτακτική την ανάγκη για ορθολογική διαχείριση των αποθεμάτων του είδους σε πανελλαδική κλίμακα, στα πλαίσια ενός προγράμματος βιοπαρακολούθησης των φυσικών αποθεμάτων, που θα διασφαλίζει την παρουσία και την ανάπτυξη των πληθυσμών του είδους.

Productivity Analysis

description: Excerpts from the report: This report contains information on the average number of man hours used in an average season to produce an acre of each of some 90 crops; number of hours used in caring for various classes of livestock for a year; number of hours used in producing livestock products, such as a hundredweight of pork, beef, milk, and a hundred dozen of eggs; and data related to the labor requirements, such as average yields of crops, number of livestock on farms, production of livestock, and certain factors for converting livestock labor requirements from a live weight to a dressed weight basis, and for computing the number of man hours needed to harvest crops of various yields. The labor requirements shown are State averages, arrived at by taking into consideration many variations from the average. They are not the result of any special survey, but were "built up" from available data collected by Federal and State agencies. Included in the labor for crop production are the hours for hauling manure, plowing and fitting the land, planting and cultivating, spraying, dusting, pruning, etc., and for harvesting and hauling the crop to storage, local market, or processing plant. The hours for livestock care and production include direct labor only for such operations as feeding, caring for, and disposing of the animals and their products.
A guiding center implementation for relativistic particle dynamics in the PLUTO code

description: We present a numerical implementation of the guiding center approximation to describe the relativistic motion of charged test particles in the PLUTO code for astrophysical plasma dynamics. The guiding center approximation (GCA) removes the time step constraint due to particle gyration around magnetic field lines by following the particle center of motion rather than its full trajectory. The gyration can be detached from the guiding center motion if electromagnetic fields vary sufficiently slow compared to the particle gyration radius and period. Our implementation employs a variable step-size linear multistep method, more efficient when compared to traditional one-step Runge Kutta schemes. A number of numerical benchmarks is presented in order to assess the validity of our implementation.

description: In this article, we investigate the modified symmetric teleparallel gravity or $f(Q)$ gravity, where $Q$ is the non-metricity, to study the evolutionary history of the universe by considering the functional form of $f(Q)=αQ^n$, where $α$ and $n$ are constants. Here, we consider the parametrization form of the deceleration parameter as $q=q_0+\frac{q_1\,z}{(1+z)^2}$ which provides the desired property for sign flip from a decelerating to an accelerating phase. We get the solution of the Hubble parameter by examining the mentioned parametric form of $q$, and then we impose the solution in Friedmann equations. Employing the Bayesian analysis for the Observational Hubble data (OHD), we estimated the constraints on the associated free parameters $(H_0,q_0,q_1)$ to determine if this model may challenge the $Λ$CDM limitations. Furthermore, the constrained current value of the deceleration parameter $q_0=-0.832^{+0.091}_{-0.091}$ shows that the present universe is accelerating. We also investigate the evolutionary trajectory of energy density, pressure, and EoS parameters to conclude the accelerating behavior of the universe. Finally, we try to demonstrate that the considered parametric form of the deceleration parameter is compatible with $f(Q)$ gravity.

description: Vulvovaginal candidiasis (VVC) is the most prevalent human candidal infection, estimated to afflict approximately 75% of all women at least once in their lifetime. It will lead to several symptoms including pruritus, vaginal soreness, and so on. Automatic whole slide image (WSI) classification is highly demanded, for the huge burden of disease control and prevention. However, the WSI-based computer-aided VCC screening method is still vacant due to the scarce labeled data and unique properties of candida. Candida in WSI is challenging to be captured by conventional classification models due to its distinctive elongated shape, the small proportion of their spatial distribution, and the style gap from WSIs. To make the model focus on the candida easier, we propose an attention-guided method, which can obtain a robust diagnosis classification model. Specifically, we first use a pre-trained detection model as prior instruction to initialize the classification model. Then we design a Skip Self-Attention module to refine the attention onto the fined-grained features of candida. Finally, we use a contrastive learning method to alleviate the overfitting caused by the style gap of WSIs and suppress the attention to false positive regions. Our experimental results demonstrate that our framework achieves state-of-the-art performance. Code and example data are available at https://github.com/cjdbehumble/MICCAI2023-VVC-Screening.

description: Report Preface: This publication is a companion report to F. M. 40, "Labor Requirements for Crops and Livestock," published in May 1943. The basic labor requirements per acre and per unit of livestock contained in F. M. 40, and additional data were used in making the following estimates of total man-hours per month and per year required by each enterprise and by all farms in each State and in the United States. The main purpose of this report is to make available to research and extension workers, and to some other groups, the large amount of data on labor requirements that were computed in laying the foundation for the development of a new series that will measure farm labor in terms of man-hour requirements. These data are basic to an understanding of the reasons for the long-time shift from peak farm loads in midsummer to peak loads in the late summer and early fall months, and the reductions in labor requirements during the war. They are necessary to an analysis of the effects of technological developments on labor needed in agriculture. The State data make possible study and analysis of geographic variations in labor productivity and the effects of technological developments on amounts of labor needed.

description: Αξιολογήθηκε η επίδραση της υπόγειας στάγδην άρδευσης στα παραγωγικά χαρακτηριστικά της καλλιέργειας των ζαχαρότευτλων, συγκρίνοντάς την με την επιφανειακή στάγδην άρδευση σε δύο περιπτώσεις: α) για το ίδιο εύρος άρδευσης και στα δύο αρδευτικά συστήματα σύμφωνα με την μετρούμενη εξατμισοδιαπνοή της καλλιέργειας (ΕΤ) και β) για εύρος άρδευσης στο μεν επιφανειακό σύστημα σύμφωνα με την καλλιεργητική πρακτική, στο δε υπόγειο σύμφωνα με την εξατμι- σοδιαπνοή της καλλιέργειας (ΕΤ). Ταυτόχρονα έγινε σύγκριση μεταξύ των επιφανειακών μεθόδων που δέχθηκαν διαφορετικές δόσεις νερού σε ίδιο εύρος άρδευσης, καθώς και μεταξύ αυτών που δέχθηκαν ίδια δόση νερού σε διαφορετικό εύρος άρδευσης. Για το σκοπό αυτό εγκαταστάθηκε πείραμα στο Αγρόκτημα του Πανεπιστημίου Θεσσαλίας, το 2004. Το πειραματικό σχέδιο ήταν Πλήρεις Τυχαιοποιη- μένες Ομάδες με 5 μεταχειρίσεις και 4 επαναλήψεις. Η άρδευση ήταν αυτοματοποιημένη και η δόση άρδευσης καθορίστηκε σύμφωνα με την εξατμισοδιαπνοή, με την βοήθεια εξατμισιμέτρου τύπου Α, σε κάλυψη 100% και 80% των αναγκών της καλλιέργειας. Τα αποτελέσματα έδειξαν υπεροχή της Υπόγειας στάγδην άρδευσης στην τελική αξία, (χρηματική), της παραγωγής έχοντας ταυτόχρονα σημαντική εξοικονόμηση νερού. Επιπλέον στην Υπόγεια μεταχείρηση παρατηρήθηκε ο μεγαλύτερος ζαχαρικός τίτλος. Ανάμεσα στις μεταχειρίσεις οι οποίες δέχθηκαν διαφορετική ποσότητα νερού με το ίδιο εύρος άρδευσης, μεγαλύτερο βάρος ριζών παρουσίασαν αυτές οι οποίες δέχθηκαν το 100% των αναγκών σε νερό. Η συγκέντρωση των μελασογόνων συστατικών, (Κ, Να και α-άμινο Ν), στις ρίζες των ζαχαρότευτλων παρουσίασε στατιστικά σημαντικές διαφορές (ρ=0,05) ανάμεσα στις μεταχειρίσεις, μόνο στην περίπτωση του Κ.

description: The paper defends the thesis that analysis of truth problem in the context of interpretations of quantum logic allows to reveal the prospect of elicitation of specifics of the relations between quantum mechanics and quantum logic in a context of modal expansions of quantum logic. It is found the way for solution of the problem of detection of features of creation of quantum-mechanical researches as a single case of semantics of "the possible worlds". Studies in the field of logic foundation of quantum physics receive the status of "possible quantum mechanics". Therefore they can be presented not simply as "truth" and "false" distinction within judgments about the physical phenomena but also as display logically possible and (or) impossible, necessary and (or) casual constructions of physical sciences.

description: In the present-day universe, magnetic fields play such essential roles in star formation as angular momentum transport and outflow driving, which control circumstellar disc formation/fragmentation and also the star formation efficiency. While only a much weaker field has been believed to exist in the early universe, recent theoretical studies find that strong fields can be generated by turbulent dynamo during the gravitational collapse. Here, we investigate the gravitational collapse of a cloud core ($\sim 10^{3}\ \rm cm^{-3}$) up to protostar formation ($\sim 10^{20}\ \rm cm^{-3}$) by non-ideal magnetohydrodynamics (MHD) simulations considering ambipolar diffusion (AD), the dominant non-ideal effects in the primordial-gas. We systematically study rotating cloud cores either with or without turbulence and permeated with uniform fields of different strengths. We find that AD can slightly suppress the field growth by dynamo especially on scales smaller than the Jeans-scale at the density range $10^{10}-10^{14}\ \rm cm^{-3}$, while we could not see the AD effect on the temperature evolution, since the AD heating rate is always smaller than compression heating. The inefficiency of AD makes the field as strong as $10^{3}-10^{5} \rm\ G$ near the formed protostar, much stronger than in the present-day cases, even in cases with initially weak fields. The magnetic field affects the inflow motion when amplified to the equipartition level with turbulence on the Jeans-scale, although disturbed fields do not launch winds. This might suggest that dynamo amplified fields have smaller impact on the dynamics in the later accretion phase than other processes such as ionisation feedback.

description: In this paper, we determine the electromagnetic effects on the complexity factor of radiating anisotropic cylindrical geometry in the background of $f(G,\mathcal{T})$ theory. The self-gravitating objects possessing inhomogeneous energy density, pressure anisotropy, heat flux, charge and correction terms appear to encounter the complexity producing phase. Herrera's orthogonal splitting method is used to identify the scalar functions in which the factor that incorporates all of the fundamental aspects of the system is assumed to be the complexity factor. We also look at the evolution of charged cylindrical matter source by selecting homologous pattern as the most basic evolutionary mode. In addition to this, homologous and complexity free conditions are utilized to address dissipative as well as non-dissipative scenarios. The complexity producing parameters throughout the evolutionary process are assessed at the end. It is concluded that the complexity of the astrophysical entities is elevated due to the contribution of charge and modified terms of this theory.

We explain the magnetic and thermodynamic properties based on the strong-rung regime. Furthermore, we find a field-induced successive phase transition in the specific heat and the nuclear spin-lattice relaxation rate 1/T1. 19F-NMR spectra for higher- and lower-temperature phases indicate partial magnetic order and incommensurate long-range order, respectively, evidencing the presence of frustration due to weak interladder couplings.

Transit Duration and Timing Variations from Binary Planets

description: Systems of two gravitationally bound exoplanets orbiting a common barycenter outside their physical radii ("binary planets") may result from tidal capture during planet-planet scattering. These objects are expected to form in tight orbits of just a few times their summed radii due to dynamical tides. As a result of their close proximity, their transits overlap heavily, leading to the deceptive illusion of a single planet of larger effective size, an effect compounded in the presence of noisy data and/or long integration times. We show that these illusory single-component transits, dubbed "chimera transits", exhibit large-amplitude Transit Duration Variation (TDV) effects on the order of hours, as well as smaller Transit Timing Variations (TTVs). We compute an analytic approximation for the transit duration upper bound, assuming binary planets with low impact parameter and orbits coplanar with the stellarcentric orbit. We verify the accuracy of our expressions against dynamical simulations of binary Jupiters using the luna algorithm, and provide a Python code for numerical calculations of the TDV signal in binary planet systems (github.com/joheenc/binary-planet-transits). Additionally, chimera transits from binary planets exhibit TTVs of detectable amplitude and high frequency, falling within the recently identified exomoon corridor. Due to their anomalous shapes, depths, and durations, such objects may be flagged as false positives, but could be clearly surveyed for in existing archives.

description: Large numbers of radiographic images are available in knee radiology practices which could be used for training of deep learning models for diagnosis of knee abnormalities. However, those images do not typically contain readily available labels due to limitations of human annotations. The purpose of our study was to develop an automated labeling approach that improves the image classification model to distinguish normal knee images from those with abnormalities or prior arthroplasty. The automated labeler was trained on a small set of labeled data to automatically label a much larger set of unlabeled data, further improving the image classification performance for knee radiographic diagnosis. We developed our approach using 7,382 patients and validated it on a separate set of 637 patients. The final image classification model, trained using both manually labeled and pseudo-labeled data, had the higher weighted average AUC (WAUC: 0.903) value and higher AUC-ROC values among all classes (normal AUC-ROC: 0.894; abnormal AUC-ROC: 0.896, arthroplasty AUC-ROC: 0.990) compared to the baseline model (WAUC=0.857; normal AUC-ROC: 0.842; abnormal AUC-ROC: 0.848, arthroplasty AUC-ROC: 0.987), trained using only manually labeled data. DeLong tests show that the improvement is significant on normal (p-value<0.002) and abnormal (p-value<0.001) images. Our findings demonstrated that the proposed automated labeling approach significantly improves the performance of image classification for radiographic knee diagnosis, allowing for facilitating patient care and curation of large knee datasets.

description: ALMA observations have revealed that many high redshift galaxies are surrounded by extended (10-15 kpc) [CII]-emitting halos which are not predicted by even the most advanced zoom-in simulations. Using a semi-analytical model, in a previous work we suggested that such halos are produced by starburst-driven, catastrophically cooling outflows. Here, we further improve the model and compare its predictions with data from 7 star-forming ($10\lesssim \rm SFR/ M_\odot \rm yr^{-1}<100$) galaxies at z=4-6, observed in the ALPINE survey. We find that (a) detected [CII] halos are a natural by-product of starburst-driven outflows; (b) the outflow mass loading factors are in the range $4\lesssimη\lesssim 7$, with higher $η$ values for lower-mass, lower-SFR systems, and scale with stellar mass as $η\propto M_*^{-0.43}$, consistently with the momentum-driven hypothesis. Our model suggests that outflows are widespread phenomena in high-z galaxies. However, in low-mass systems the halo extended [CII] emission is likely too faint to be detected with the current levels of sensitivity.

description: The $^{1}S_{0}$ nucleonic superfluids are investigated within the relativistic mean-field model and Bardeen-Cooper-Schrieffer theory in hyperonic neutron stars. The $^{1}S_{0}$ pairing gaps of neutrons and protons are calculated based on the Reid soft-core interaction as the nucleon-nucleon interaction. We have studied particularly the influence of hyperons degrees of freedom on the $^{1}S_{0}$ nucleonic pairing gap in neutron star matter. It is found that the appearance of hyperons has little impact on baryonic density range and size for the $^{1}S_{0}$ neutronic pairing gap, the $^{1}S_{0}$ protonic pairing gap also decreases slightly in this region $ρ_B=0.0-0.393$ fm$^{-3}$. However, if baryonic density becomes greater than 0.393 fm${^{-3}}$, the $^{1}S_{0}$ protonic pairing gap obviously increases. In addition, the protonic superfluid range is obviously enlarged due to the presence of hyperons. In our results, the hyperons change the $^{1}S_{0}$ protonic pairing gap which must change the cooling properties of neutron stars.

description: Abstract: English language proficiency and test anxiety among Spanish speakers might affect performance on working memory (WM) tasks, not taking this into consideration, could result in the unreliable measurement of true WM capacity and true ability on tasks that require WM involvement. WM was defined as a system with a limited storage and temporal capacity for information-processing, which also involves attentional control and manipulation of information (Baddeley, 2003). WM performance has been found to be positively affected by bilingualism on WM tasks requiring attentional control (Engle, 2002). Furthermore, the information processing aspect of WM has been found to be negatively affected by test anxiety (Lee, 1999). As such, the present study is aiming to investigate the effects of test anxiety on working memory performance among Spanish/English speakers. The study will use a t-test, analysis of variance, and multiple regression to explore results.

description: The PYTHIA program is a standard tool for the generation of events in high-energy collisions, comprising a coherent set of physics models for the evolution from a few-body hard process to a complex multiparticle final state. It contains a library of hard processes, models for initial- and final-state parton showers, matching and merging methods between hard processes and parton showers, multiparton interactions, beam remnants, string fragmentation and particle decays. It also has a set of utilities and several interfaces to external programs. PYTHIA 8.2 is the second main release after the complete rewrite from Fortran to C++, and now has reached such a maturity that it offers a complete replacement for most applications, notably for LHC physics studies. The many new features should allow an improved description of data.

Abstract:

The benefits of scientific collaboration through co-authorship are widely recognized, which has driven a growing trend in the number of authors per document. However, the increase in collaboration has been accompanied by a set of research misconduct, where individuals included as authors in a publication do not actually meet the required criteria for authorship. This article details the criteria that every person must meet to be considered an author of a publication according to the International Committee of Medical Journal Editors. It is the responsibility of the authors, and not the editors of the journal to which the document is submitted, to determine and verify that all persons named as authors meet the four criteria. Finally, the question of whether technology assisted by artificial intelligence (AI) can be considered the author is addressed.

Resumen:

Los beneficios de la colaboración científica mediante la coautoría son ampliamente reconocidos, la cual ha impulsado una tendencia creciente en el número de autores por documento. Sin embargo, el incremento en la colaboración ha venido acompañado de un conjunto de malas prácticas en investigación, donde individuos incluidos como autores en una publicación no cumplen realmente con los criterios requeridos para la autoría. En este artículo se detallan los criterios que debe cumplir toda persona para ser considerada como autora de una publicación según el International Committee of Medical Journal Editors. Es responsabilidad de los autores y no de los editores de la revista a la cual se remite el documento, determinar y comprobar que todas las personas nombradas como autores cumplen con los cuatro criterios. Finalmente, se aborda la pregunta de si la tecnología asistida por inteligencia artificial (IA) puede ser considerada como autora.

description: The combination of simple dynamics, small number of available decay channels, and extremely well controlled radiative and loop corrections, make charged pion decays a sensitive means for testing the underlying symmetries and the universality of weak fermion couplings, as well as for improving our understanding of pion structure and chiral dynamics. This paper reviews the current state of experimental study of the allowed rare decays of charged pions: (a) leptonic, $π^+ \to e^+ν_e$, or $π_{e2}$, (b) radiative, $π^+ \to e^+ν_eγ$, or $π_{e2γ}$, and $π^+ \to e^+ν_e e^+e^-$, or $π_{e2ee}$, and (c) semileptonic, $π^+\to π^0 e^+ ν$, or $π_{e3}$. Taken together, the combined data set presents an internally consistent picture that also agrees well with standard model predictions. The internal consistency is illustrated well by the $π_{e2}$ branching ratio of $(R_{e/μ}^π)^{\rm PIBETA} = (1.2366 \pm 0.0064) \times 10^{-4}$ extracted in this work from the PIBETA measurement of the $π_{e3}$ decay and the current best value for the CKM matrix element $V_{ud}$. However, even after the great progress of the recent decades, experimental precision is lagging far behind that of the theoretical description for all above processes. We review the implications of the present state of knowledge and prospects for further improvement in the near term.

title: Fractured brotherhoods: ethnic identity in multi-ethnic violent political organisations
Creators: name: Micheni, Makena Nyawira

description: In the literature on political violence in sub-Saharan Africa, ethnic ties have been highlighted as significant and central to insurgent organizations. However, a fixation with ethnicity or 'tribalism' historically led to conflicts being labelled as ethnic in nature, or ethnicity being seen as the driving catalyst of wars in the region. This approach resulted in a false dichotomy in classifying conflicts in sub-Saharan Africa as either "ethnic" or "non-ethnic," limiting our understanding of the role, nuance, and effects of ethnicity in conflicts that are coded as non-ethnic. To address this issue, this project focuses on a "hard" case - the case of Boko Haram - to explore the role of ethnicity in conflicts not typically classified as ethnic. The dissertation examines when, why, and how ethnicity emerges as a mechanism of organization and control within armed groups, surpassing the overarching supra-identity, despite attempts and claims of cross-ethnic reach and appeal. The study finds that, despite professing an ideology that transcends ethnic identity, ethnicity can play a crucial role in a number of key areas, including supplementing religious identity, ideology, or doctrine. Moreover, while Boko Haram was able to create a new shared identity centred around their supra-ethnic Salafi jihadism, for some, the significance of ethnic identity and ties did not disappear, despite the group's transethnic ethos and ideology. In some circumstances, ethnicity became so salient that it influenced group dynamics despite the professed religious basis of the group. The study argues that when group leaders are appointed to leadership positions for reasons that are not contingent on their complete socialization into the group, they are more likely to foster an environment where ethnic factions, identities, and privileges thrive. Given the power they possess, leaders can permit and even propagate potential divisions, siding with co-ethnics when disputes occur instead of maintaining more neutral positions.
