description: Στην παρούσα εργασία αναπτύχθηκε μία μοριακή τεχνική, στόχος της οποίας είναι ο εύκολος, γρήγορος και αποτελεσματικός προσδιορισμός της προέλευσης, σε επίπεδο είδους, του κρέατος που περιέχεται σε τρόφιμα. Η ανάλυση πραγματοποιήθηκε στο μιτοχονδριακό DNA που απομονώθηκε από μυϊκό ιστό νωπού ή επεξεργασμένου κρέατος πουλερικών (όρνιθα, γαλοπούλα, πάπια, χήνα, φασιανός, πέρδικα, μπεκάτσα, στρουθοκάμηλος, ορτύκι και τσίχλα). Η τεχνική που εφαρμόστηκε ήταν η PCR-RFLP. Αρχικά ενισχύθηκε με την μέθοδο PCR τμήμα των γονιδίων Cyt b μεγέθους 376bp και 12S rRNA μεγέθους 485bp. Οι ολιγονουκλεϊνικοί εκκινητές που χρησιμοποιήθηκαν ήταν κοινοί για τα παραγωγικά ζώα (universal primers). Στην συνέχεια πραγματοποιήθηκαν πέψεις με δεκατέσσερα διαφορετικά ένζυμα περιορισμού και ηλεκτροφορητικός διαχωρισμός των τμημάτων περιορισμού σε πηκτή πολυακρυλαμίδης. Από την ανάλυση των αποτελεσμάτων συμπεραίνουμε ότι το γονίδιο 12S rRNA είναι περισσότερο πολυμορφικό έναντι του γονιδίου Cyt b όσον αφορά τα εξεταζόμενα είδη. Έτσι θεωρήθηκε καταλληλότερος μοριακός δείκτης για χρήση σε μελέτες διαχωρισμού πουλερικών. Η πέψη του 12S rRNA με το ένζυμο περιορισμού Acil διαχώρισε επιτυχώς και τα δέκα πτηνά, παρουσιάζοντας ειδικά πρότυπα για το κάθε είδος ικανά να δώσουν μία μονοσήμαντη απάντηση για την προέλευση των δειγμάτων που έχουν αναλυθεί. Η μέτρια επεξεργασία του κρέατος δεν εμπόδισε την ταυτοποίηση του, αφού παρουσίασε όμοια πρότυπα με το νωπό. Τέλος η μέθοδος αυτή κρίθηκε ικανή προς ανίχνευση μιγμάτων κρέατος, πράγμα που θα μπορούσε να την καταστήσει πολύτιμο εργαλείο για τον έλεγχο της νοθείας στις βιομηχανίες κρέατος και τις επιχειρήσεις εστίασης.

description: Sunquakes are seismic emissions visible on the solar surface, associated with some solar flares. Although discovered in 1998, they have only recently become a more commonly detected phenomenon. Despite the availability of several manual detection guidelines, to our knowledge, the astrophysical data produced for sunquakes is new to the field of Machine Learning. Detecting sunquakes is a daunting task for human operators and this work aims to ease and, if possible, to improve their detection. Thus, we introduce a dataset constructed from acoustic egression-power maps of solar active regions obtained for Solar Cycles 23 and 24 using the holography method. We then present a pedagogical approach to the application of machine learning representation methods for sunquake detection using AutoEncoders, Contrastive Learning, Object Detection and recurrent techniques, which we enhance by introducing several custom domain-specific data augmentation transformations. We address the main challenges of the automated sunquake detection task, namely the very high noise patterns in and outside the active region shadow and the extreme class imbalance given by the limited number of frames that present sunquake signatures. With our trained models, we find temporal and spatial locations of peculiar acoustic emission and qualitatively associate them to eruptive and high energy emission. While noting that these models are still in a prototype stage and there is much room for improvement in metrics and bias levels, we hypothesize that their agreement on example use cases has the potential to enable detection of weak solar acoustic manifestations.

description: Recent advances in optimization theory have shown that smooth strongly convex finite sums can be minimized faster than by treating them as a black box "batch" problem. In this work we introduce a new method in this class with a theoretical convergence rate four times faster than existing methods, for sums with sufficiently many terms. This method is also amendable to a sampling without replacement scheme that in practice gives further speed-ups. We give empirical results showing state of the art performance.
Natural history, behavior, and bacterial microbiomes of a socially polymorphic spider, Anelosimus studiosus

description: Anelosimus studiosus is a unique spider; throughout its range from Argentina to New England, most adult females are solitary and subsocial (provide maternal care). However, in the northernmost parts of its range in the United States, adult females sometimes live in cooperative aggregations. While this social polymorphism has been well defined in specific regions of A. studiosus’ range, it is not so thoroughly described elsewhere. Therefore, I first describe the aggregative behavior, natural history, and population sex ratios for A. studiosus across a latitudinal gradient in Texas (Chapters 1 and 2). I discovered that A. studiosus tend to aggregate at higher latitudes in Texas, but that this tendency was not correlated with female-biased primary sex ratios, suggesting that outbreeding still occurs in these populations. I then compared the social behavior of A. studiosus from Texas populations to those further east (Alabama and Tennessee) using tests of aggressive tendency (Chapter 3). Individuals from western and eastern populations vary in aggressive tendency, but I was unable to corroborate previous findings that different measures of aggressive tendency correlate. Finally, I used 16S rRNA metagenomics to describe the bacterial microbiome of A. studiosus (Chapter 4). Similar to some spider species but unlike many other animals, A. studiosus do not harbor a consistent, core bacterial community, and instead, their bacterial communities reflect their rearing environment and diet. In all, this dissertation on the socially polymorphic Anelosimus studiosus adds to a growing body of literature on the complexity of animal personalities, and their effect on organismal biology.

description: Much of the progress achieved in understanding plasticity and failure in amorphous solids had been achieved using experiments and simulations in which the materials were loaded using strain control. There is paucity of results under stress control. Here we present a new method that was carefully geared to allow loading under stress control either at $T=0$ or at any other temperature, using Monte-Carlo techniques. The method is applied to a model perfect crystalline solid, to a crystalline solid contaminated with topological defects, and to a generic glass. The highest yield stress belongs to the crystal, the lowest to the crystal with a few defects, with the glass in between. Although the glass is more disordered than the crystal with a few defects, it yields stress is much higher than that of the latter. We explain this fact by considering the actual microscopic interactions that are typical to glass forming materials, pointing out the reasons for the higher cohesive nature of the glass. The main conclusion of this paper is that the instabilities encountered in stress-control condition are the identical saddle-node bifurcation seen in strain-control. Accordingly one can use the latter condition to infer about the former. Finally we discuss temperature effects and comment on the time needed to see a stress controlled material failure.

We consider flavours of different masses that produce spherical cavities with radii corresponding to the quark masses. The positive beta function blows at some large radial distance corresponding to the Landau pole of the theory. We explore the Wilson loop between two families of light and heavy quarks and observe a screening of the heavy light potential.

description: We have analysed Optical Gravitational Lensing Experiment photometry for first overtone classical Cepheids in the Large and Small Magellanic Clouds in search for additional periodicities beyond radial modes. We have used standard consecutive prewhitening technique in some cases followed by time-dependent prewhitening. We report new candidates for double-mode radial pulsations. However, majority of signals we have detected cannot be interpreted in terms of radial modes. We report 516 double-periodic stars with period ratios, $P_{\rm x}/P_{\rm 1O}$, in the range 0.60 and 0.65. We study the properties of this class and implications for model explaining these periodicities. We also report 28 stars in which additional variability is of longer period, below radial fundamental mode, with median period ratio, $P_{\rm 1O}/P_{\rm x}$, of 0.684. This class is an analogue of a class known in RR Lyrae stars. Hundreds of other signals were detected that cannot be attributed to radial modes or the above-mentioned classes. Statistical properties of these signals are analysed. We suggest that majority of these signals correspond to non-radial modes. In particular, a significant fraction can be attributed to non-radial modes of moderate degrees, tightly connected to a class with period ratios in between 0.60 and 0.65. In tens of stars, close to radial mode frequency, relatively large-amplitude and coherent signals are observed, that may represent yet another class. In 27 stars periodic modulation of pulsation was detected. Differences in additional frequency content between the two Clouds are discussed.

В исследовании приняли участие 30 лыжников-гонщиков (средний возраст – 19,5±1,8 года). 12 спортсменов основной группы на протяжении 21 дня принимали специализированный пищевой продукт (из расчета 0,5–1,5 г на 1 кг массы тела) на основе ферментированной молочной сыворотки, содержащий аминокислоты, витамины, микрои макроэлементы, живую культуру молочнокислых бактерий: L. lactis, L. thermophilus, L. bulgaricus (1,2×108 КОЕ/см3), за 30 мин до тренировки и через 30 мин после нее. Контрольную группу составили 18 лыжников, принимавших плацебо (раствор пищевого крахмала аналогичной консистенции). После курсового приема продуктов у лыжников статистически значимо (р<0,05) выросло содержание гемоглобина на 6%, лейкоцитов на 10% за счет увеличения числа гранулоцитов на 32%, а также сегментоядерных нейтрофилов на 16%, выявлена тенденция к росту численности эритроцитов на 7% при значимом снижении содержания лимфоцитов на 19%. Если показатель скорости оседания эритроцитов у лыжников группы сравнения увеличился на 41% (р<0,05), то у спортсменов основной группы снизился на 16% (р>0,05). После применения пищевого продукта методом лазерной допплеровской флоуметрии установлены тенденция к повышению перфузии крови на 15%, статистически значимое повышение флакса на 53%, в основе которого лежит улучшение работы внутренних механизмов регуляции микроциркуляции. По данным математического анализа сердечного ритма, снизилась централизация управления на фоне повышения активности автономного механизма управления работой сердца. Выявленные функциональные изменения обеспечили повышение абсолютной (на 31%, p<0,05) и относительной (на 33%, p<0,05) физической работоспособности и аэробной выносливости лыжников-гонщиков, способствовали улучшению кратковременной памяти. Сделан вывод о целесообразности использования специализированного пищевого продукта для повышения адаптационного потенциала организма спортсменов при воздействии систематических физических нагрузок.

description: From grocery shopping and cooking to house cleaning and dog-walking, the possibility of outsourcing just about anything has become more accessible than ever before. The appeal of the so-called time-saving purchases is clear: people can buy free time and reduce the stress associated with feeling that they have much to do with too little time to do it. Indeed, the supply of time-saving services continues to increase, covering wider range of tasks and population. Even when people do not actively seek time-saving services, it is likely that they will frequently encounter such options. In this paper, I investigate one downstream consequence of this new way of taking care of personal tasks – outsourcing life – by testing whether mere exposure to a time-saving option undermines intrinsic motivation. Across five studies, I demonstrate that mere presence of an option to pay money to buy out of an activity reduces how much the activity is enjoyed as well as how much of the activity people subsequently do. Findings show that this undermining effect primarily occurs by inducing people to treat their everyday activities as mere commodities and thus eroding the value of performing the activities. I also show that this undermining effect persist even when people choose not to use the time-saving option while the undermining effect is eliminated when time-saving options are not priced. Furthermore, exposure to time-saving services undermined intrinsic motivation only for activities that people initially perceived to be pleasant (vs. unpleasant). Lastly, I explore other psychological consequences of the mere exposure of time-saving services, including perceived time pressure, subjective well-being, enjoyment in other pleasurable activities, and activation of a market-oriented mindset. I end this paper by discussing the implications for time-saving services and for societal influence on intrinsic motivation.

description: We review the current understanding of the uniform two-dimensional (2D) Fermi gas with short-range interactions. We first outline the basics of two-body scattering in 2D, including a discussion of how such a 2D system may be realized in practice using an anisotropic confining potential. We then discuss the thermodynamic and dynamical properties of 2D Fermi gases, which cold-atom experiments have only just begun to explore. Of particular interest are the different pairing regimes as the interparticle attraction is varied; the superfluid transition and associated finite-temperature phenomenology; few-body properties and their impact on the many-body system; the Fermi polaron problem; and the symmetries underlying the collective modes. Where possible, we include the contributions from 2D experiment. An underlying theme throughout is the effect of the quasi-2D geometry, which we view as an added richness to the problem rather than an unwanted complication.

Fast formation and assembly strategies

description: Efficient product development constitutes a workflow in which design, analysis, optimization, and manufacturing all work in unison to develop, test, measure, refine and validate a product from first concept through detailed design to final prototype. There are several key challenges, however, that have hampered such a workflow for decades. The main bottleneck is the lack of a single, conforming representation of geometry at all stages of the design process enabling true interoperability across computer aided design (CAD), analysis (CAE) and manufacturing (CAM). Isogeometric analysis was introduced to improve the interoperability between computer aided design and finite element analysis by unifying the underlying technology that supports both disciplines. Its promise is to eliminate the tedious process of geometry repair, feature removal, and mesh generation, while, at the same time, maintaining a single exact representation of geometry at all stages of the design process. Although isogeometric analysis has proven its fidelity as an analysis technology, some key issues remain. Specifically, * Current CAD technologies describe geometry by means of the boundary representation or simply B-rep. Boolean operations, ubiquitous in computer aided design, use a process called trimming that leads to a non-conforming description of geometry that is un-editable and incompatible with all downstream applications, thereby inhibiting true interoperability across the design-through-analysis process. * The high cost of formation of element arrays and assembly into the global system limits isogeometric analysis to low polynomial orders, typically degree two or three. The same may be said for classical finite element analysis. Classical formation and assembly routines scale as O(p⁹) per degree of freedom, while the optimal scaling with polynomial degree is O(p³). The main objective of this work is the development of several supporting technologies that address these two issues and thereby enable stable, accurate and efficient high polynomial-order isogeometric analysis for applications in solid mechanics.

description: Family Actiniidae Rafinesque, 1815  In the revisionary work by England (1987), the clownfish-hosting species Entacmaea quadricolor was moved from family Actiniidae to the Stichodactylidae based on the presence of a type of cnidae (microbasic amastigophores) in the column, tentacles, or both regions in members of Stichodactylidae but not in those of Actiniidae. However, despite England’s (1987) claims, this type of cnidae is also present in the column and/or tentacles of other species within Actiniidae (e.g. Isoaulactinia, Phialoba, see Barragán et al. 2019) and thus this feature does not differentiate these families. This fact, together with recent molecular results that do not support a close relationship between E. quadricolor and members of Stichodactylidae (Titus et al. 2019; Yap et al. 2021, 2023), we consider E. quadricolor within family Actiniidae until a comprehensive revision of the group is available.
The other fish-hosting taxon included within Actiniidae was the former Macrodactyla doorensis, which Fautin (2016) returned to the genus Condylactis Duchassaing de Fombressin & Michelotti, 1864 because the generic name Macrodactyla Haddon, 1898 had been claimed to be a junior homonym of a coleopteran genus and thus unavailable for use in sea anemones (Fautin 2016, Neave 1940). However, Yap et al. (2023) clarified that the name Macrodactyla is not a junior homonym of a coleopteran genus and it can be retained as a genus name for sea anemones. In addition, Yap et al. (2023) showed that former M. doreensis is not closely related to the type species of Macrodactyla but nested within other species of Heteractis and created a new combination name for this species, Heteractis doreensis (Quoy & Gaimard, 1883), based on molecular data.

Intervention

description: This proposal aims to draw upon previously applied interventions in the field of mental health service provider burnout to create an accessible, efficient, and cost-effective technology-based intervention option for providers. The understanding of burnout as described in this paper draws from a multifaceted definition of burnout proposed by Maslach et al. (1993, 1996), and uses Buunk & Schaufeli’s (1993) discussion of social comparison theory (e.g., Taylor, Buunk, & Aspinwall, 1990; Taylor & Lobel, 1989) and social exchange theory (e.g., Buunk & VanYperen, 1991; Walster, Berscheid, & Walster, 1978), to conceptualize burnout in mental service providers. The proposed study will use a pre- and post-test design to determine efficacy, as well as a six-week and six-month follow up. Results from the proposed study could inform future burnout interventions for mental health service providers

description: We consider a cosmological model dominated by stiff fluid with a constant bulk viscosity. We classify all the possible cases of the universe predicted by the model and analyzing the scale factor, density as well as the curvature scalar. We find that when the dimensionless constant bulk viscous parameter is in the range $0 < \barζ<6$ the model began with a Big Bang, and make a transition form the decelerating expansion epoch to an accelerating epoch, then tends to the de Sitter phase as $ t\to \infty$. The transition into the accelerating epoch would be in the recent past, when $46$ the model doesn't have a Big Bang and suffered an increase in the fluid density and scalar curvature as the universe expands, which are eventually saturates as the scale factor $a \to \infty$ in the future. We have analyzed the model with statefinder diagnostics and find that the model is different from $Λ$CDM model but approaches $Λ$CDM point as $a \to \infty.$ We have also analyzed the status of the generalized second law of thermodynamics with apparent horizon as the boundary of the universe and found that the law is generally satisfied when $0 \leq \barζ<6$ and for $\barζ>6$ the law is satisfied when the scale factor is larger than a minimum value.

description: In the present paper we give an overview on multiscale algorithms for the solution of boundary integral equations which are based on the use of wavelets. These methods have been introduced first by Beylkin, Coifman, and Rokhlin [5]. They have been developed and thoroughly investigated in the work of Alpert [1], Dahmen, Proessdorf, Schneider [16-19], Harten, Yad-Shalom [25], v.Petersdorff, Schwab [33-35], and Rathsfeld [39-40]. We describe the wavelet algorithm and the theoretical results on its stability, convergence, and complexity. Moreover, we discuss the application of the method to the solution of a two-dimensional scattering problem of acoustic or electromagnetic waves and to the solution of a fixed geodetic boundary value problem for the gravity field of the earth. The computational tests confirm the high compression rates and the saving of computation time predicted by the theory.

description: Parallelizable numerical methods for solving large scale DAE systems are developed at the level of differential, nonlinear and linear equations. For this the subsystem-wise structure of the DAE systems based on unit-oriented modelling is explored. Partitionings are used to parallelize waveform relaxation and structured Newton methods. Initial values are computed with a modified Newton method. To solve large sparse systems of linear equations a special Gaussian elimination method is used. The algorithms were implemented on a CRAY C90 vector computer, as well as on both, moderately parallel CRAY J90 vector computers and massively parallel CRAY T3D machines. The methods were tested using several real life examples.

description: Οι λεκτικές υποδείξεις ή ερωτήσεις είναι μεταξύ άλλων, ένας από τους τρόπους παροχής ερεθίσματος (Chen & Cone 2003), που μπορεί να χρησιμοποιήσει ένας παιδαγωγός για την παρουσίαση ενός κινητικού θέματος ή προβλήματος. Σύμφωνα με τις Mayesky, (1998) και Pica, (2000) ένας τύπος ερώτησης που επεκτείνει την δημιουργική σκέψη ενός παιδιού, ξεκινά με τον ακόλουθο τρόπο: «Με πόσους διαφορετικούς τρόπους...;» Αυτή η τεχνική διδασκαλίας χρησιμοποιήθηκε στην παρούσα έρευνα και η συγκεκριμένη πρόταση δομήθηκε με τρεις διαφορετικούς τρόπους ως: καταφατική πρόταση, καταφατική πρόταση με θετική πρόκληση και ερωτηματική πρόταση. Σκοπός της παρούσας έρευνας ήταν να εξετάσει την επίδραση των παραπάνω τριών τύπων λεκτικών οδηγιών στην αποκλίνουσα κινητική ικανότητα παιδιών προσχολικής ηλικίας. Η αποκλίνουσα κινητική ικανότητα μπορεί να παρατηρηθεί μέσω δύο εκ των τριών μετρήσεων της κινητικής δημιουργικότητας - την ευχέρεια και την ευελιξία - και αυτά ήταν τα κριτήρια που χρησιμοποιήθηκαν για την αξιολόγηση της σε δυο βασικές κινητικές δεξιότητες, το τρέξιμο και την αναπήδηση. Το τελικό δείγμα αποτελούνταν από 54 παιδιά (27 αγόρια και 27 κορίτσια) που επιλέχθηκαν τυχαία από 4 νηπιαγωγεία της Θεσσαλονίκης. Η αξιολόγηση της κινητικής δημιουργικότητας βασίστηκε στην πρώτη δοκιμασία της δέσμης TCAM (Thinking Creatively in Action and Movement) του Torrance (1981) και καταγράφηκε μέσω βιντεοσκόπησης σε ειδικά πρωτόκολλα αξιολόγησης. Χρησιμοποιήθηκε για κάθε μια από τις εξαρτημένες μεταβλητές (ευχέρεια - ευελιξία), ανάλυση διακύμανσης 2X3 (φύλο X τύποι οδηγιών) με επαναλαμβανόμενες μετρήσεις στον τελευταίο παράγοντα, ξεχωριστά για κάθε μια από τις βασικές κινητικές δεξιότητες, για να εξακριβωθεί εάν υπάρχουν σημαντικές διαφορές στην αποκλίνουσα κινητική ικανότητα των παιδιών προσχολικής ηλικίας. Τα αποτελέσματα και στην ευχέρεια και στην ευελιξία, έδειξαν στατιστικά σημαντικές διαφορές μεταξύ των τριών τύπων οδηγιών για το τρέξιμο (F2,io4= 24,099, ρ

description: The modified scalar boson propagator due to the presence of a hyperplane semi-transparent mirror is computed. From this, the classical interaction between static charges and the mirror is investigated employing delta-like potentials and sources. Although the calculations for hyperplane mirrors are performed in arbitrary dimensions, and in a completely general way, it is shown that the results give rise to the usual image method as a particular case. The interaction between a point-like mirror and a point-like source is also considered in $3+1$ dimensions, where a central $1/R^{2}$ attractive potential is also obtained as a special case.

description: The goal of this dissertation is to study the potential of Raman spectroscopy in improving the clinical diagnosis of skin cancer, including two main applications: noninvasive screening of melanoma skin cancer and surgical margin detection of nonmelanoma skin cancer. Skin cancer is the most common type of malignancy, accounting for over 5.4 million cases and 10 thousand deaths per year in the United States alone. Like most cancers, the current “gold standard” diagnosis relies on biopsy and histopathology, which is invasive, time-consuming, and costly. Moreover, large numbers of benign lesions are biopsied for melanoma diagnosis, resulting in substantial financial burden and patient discomfort. Therefore, an urgent need exists to develop a noninvasive, fast, and accurate method for skin cancer detection. The first part of the dissertation focuses on exploring the biophysical origin of in vivo melanoma detection. Our group has previously reported on the development of a clinical Raman spectroscopy system towards spectral biopsy of skin; however, the biochemical changes that Raman spectroscopy relies on for accurate melanoma diagnosis remained unclear. As a result, we proposed a biophysical inverse model to address this issue. To build the model, we established a custom confocal Raman microscope to extract in situ human skin constituents spanning normal and various diseased states. Our results indicate collagen, elastin, keratin, cell nucleus, triolein, ceramide, melanin, and water are the most important model components. Furthermore, collagen and triolein are the most relevant markers to discriminate malignant melanoma from benign nevi. The second part of the dissertation discusses the biophysical basis of nonmelanoma skin cancer margin delineation. We discovered the diagnostic markers to accurately differentiate tumor from normal skin, which is critical to maximize positive patient outcomes in skin cancer surgery. The biochemical changes derived from our model were highly correlated with histopathological diagnosis. We further demonstrated the feasibility of a superpixel acquisition approach for rapid classification of tumor boundaries in skin biopsies. Our results suggest Raman spectroscopy will be a powerful tool for intraoperative surgical guidance

description: Binary stellar evolution calculations predict that Chandrasekhar-mass carbon/oxygen white dwarfs (WDs) show a radially varying profile for the composition with a carbon depleted core. Many recent multi-dimensional simulations of Type Ia supernovae (SNe Ia), however, assume the progenitor WD has a homogeneous chemical composition. In this work, we explore the impact of different initial carbon profiles of the progenitor WD on the explosion phase and on synthetic observables in the Chandrasekhar-mass delayed detonation model. Spectra and light curves are compared to observations to judge the validity of the model. The explosion phase is simulated using the finite volume supernova code LEAFS, which is extended to treat different compositions of the progenitor WD. The synthetic observables are computed with the Monte Carlo radiative transfer code ARTIS. Differences in binding energies of carbon and oxygen lead to a lower nuclear energy release for carbon depleted material; thus, the burning fronts that develop are weaker and the total nuclear energy release is smaller. For otherwise identical conditions, carbon depleted models produce less Ni-56. Comparing different models with similar Ni-56 yields shows lower kinetic energies in the ejecta for carbon depleted models, but only small differences in velocity distributions and line velocities in spectra. The light curve width-luminosity relation (WLR) obtained for models with differing carbon depletion is roughly perpendicular to the observed WLR, hence the carbon mass fraction is probably only a secondary parameter in the family of SNe Ia.

description: Navigation is one of the most heavily studied problems in robotics, and is conventionally approached as a geometric mapping and planning problem. However, real-world navigation presents a complex set of physical challenges that defies simple geometric abstractions. Machine learning offers a promising way to go beyond geometry and conventional planning, allowing for navigational systems that make decisions based on actual prior experience. Such systems can reason about traversability in ways that go beyond geometry, accounting for the physical outcomes of their actions and exploiting patterns in real-world environments. They can also improve as more data is collected, potentially providing a powerful network effect. In this article, we present a general toolkit for experiential learning of robotic navigation skills that unifies several recent approaches, describe the underlying design principles, summarize experimental results from several of our recent papers, and discuss open problems and directions for future work.

description: The ability to measure, predict, and compute tsunami flow velocities is of importance in risk assessment and hazard mitigation. Substantial damage can be done by high velocity flows, particularly in harbors and bays, even when the wave height is small. Moreover, advancing the study of sediment transport and tsunami deposits depends on the accurate interpretation and modeling of tsunami flow velocities and accelerations. Until recently, few direct measurements of tsunami velocities existed to compare with model results. During the 11 March 2011 Tohoku Tsunami 328 current meters were in place around the Hawaiian Islands, USA, that captured time series of water velocity in 18 locations, in both harbors and deep channels, at a series of depths. We compare several of these velocity records against numerical simulations performed using the GeoClaw numerical tsunami model, based on solving the depth-averaged shallow water equations with adaptive mesh refinement, to confirm that this model can accurately predict velocities at nearshore locations. Model results demonstrate tsunami current velocity is more spatially variable than wave form or height and therefore may be a more sensitive variable for model validation.

description: In this letter, we extend the recent black hole solution with spherical symmetry [Phys. Lett. B \textbf{835} (2022), 137546], to a new class of black hole solutions with different topology, namely, a torus-like black hole and a black string in the presence of the cosmological constant. We have used the regularized expressions for the gravitational and the electromagnetic potentials, then we derived the corrections to the energy density and, finally, the black hole solutions are obtained which are regular in the limit $r \to 0$. Interestingly, it is found that the total mass of the black hole is corrected due to the regularized self-energy of the electrostatic field. In the special limit, we recover the well-known solutions in the literature.

Investigating the dynamics of resilience in the context of work and sport

description: The construct of psychological resilience across both work and sports contexts has been inconsistently conceptualised. Increasingly, a dynamic model of resilience is described in order to address varying experiences in which performers in both contexts sustain and rebound from diverse challenges. Psychological resource theories explain how various resources coincide with resilience and may interact with one another to facilitate the maintenance, disruption and reintegration of resilience. The aim of this research is to examine the dynamics of resilience and to explain change over both short and longer timeframes in two achievement contexts (work and sport). Using a four wave longitudinal study with 101 participants, this research investigates how resilience changes both over time and in relation to varying magnitudes of adversity. It is also hypothesised that both threat and challenge appraisals would be predicted by resilience and that a history of competitive sports would positively influence resilience processes at work, later in life. Latent growth modelling reveals statistically significant variation in resilience across time in the elevation and rate of change of the individual resilience growth trajectories. furthermore, the findings indicate that employees’ resilience capacity and their ability to maintain in goal directed work during stress was strongly predicted by higher challenge appraisals and lower threat appraisals. Those employees who had persisted in sport past secondary education were significantly better predictors of resilience processes rather than those who had disengaged earlier. Results offer empirical evidence of individual resilience change as a function of both time and adversity. The multi-wave design permits comprehensive assessment of the change in resilience over time in relation to adversity, appraisals and past life experiences. Researchers and practitioners are encouraged to develop resilience interventions for specific predictable adversities in sport and work. Building strategies around the dual pathway model will promote preventive and reintegrative resilience approaches, optimising performance episodes and well-being in ongoing sport and work endeavours.
