description: Aktuelle Entwicklungen in den digitalen Methoden der Archäologie suchen nach Lösungen für eine fachspezifisch adäquate Repräsentation chronologischer Konzepte, sowie deren persistente Adressierbarkeit. In diesem Paper wird ein konzeptioneller Vorschlag zur Lösung des archäologisch-relativchronologischen Problems mittels digitaler Methoden vorgestellt. Einerseits werden Zeitkonzepte und ihr relativchronologisches Verhältnis zueinander digital aufgearbeitet und im Semantic Web zur Verfügung gestellt. Neben Geodia, ein online-Portal für die Visualisierung von zeitlichen, geographischen und materiellen Aspekten antiker Kulturen im Mittelmeerraum und PeriodO, das als online-Gazetteer Zeitbegriffe als Linked Open Data anbietet, entwickeln das i3mainz und das DAI im Rahmen des Projekts ChronOntology eine regelbasierte Software-Architektur, die auch komplexe Zeitbegriffe in ihren Abhängigkeiten und räumlichem Kontext repräsentiert. Andererseits entstehen relativchronologische Materialzeitstufen aus einem bottom-up-Verfahren anhand datierter Fundkomplexe. Diese vom Fundmaterial heraus erarbeiteten Zeitkonzepte lassen sich in ihren relativen Bezügen quantifizieren, adressieren und digital verarbeiten. Konkret können relativchronologische Zeitangaben als Intervalle verstanden werden, die in 13 unterschiedlichen Arten semantisch verarbeitet werden können (Allen 1983; Freksa 1992). Das herausfordernde ist, dass Beschreibungen von z.B. Gefäßformen als Typologien zum Aufbau relativer Chronologien verwandt wurden, an denen wiederum Zeitkonzepte gekoppelt wurden. Dies kann mit der Keramik-Forschungsdatenbank "Samian" des RGZM sichtbar gemacht werden. Der digitale Umgang mit chronologischen Kreisargumentationen bildet ein methodisches Gerüst, das auch für die Mittelalterarchäologie weiterentwickelt werden kann, wenn feingranulierte digitale Datensätze mittelalterlicher Großmanufakturen von z.B. Siegburger Schnellen oder Goudaer Tonpfeifen vorliegen.

description: This hands-on learning activity explores the interconnectedness of food, energy, and water (FEW) systems through engagement in the FAMU SEED (Sustainable Education and Engagement Development) Community Garden. As a key part of Florida A&M University’s School of the Environment—Sustainability Institute’s educational hub, the garden provides a dynamic platform for experiential learning. Located on a 0.25-acre plot, the garden integrates renewable energy, water conservation, and sustainable agriculture practices to demonstrate real-world sustainability solutions. Students actively participate in analyzing solar energy output from a 100-kW panel array, monitoring water usage from a rainwater harvesting system, and evaluating crop health and productivity.
Through fieldwork, data analysis, group discussions, and presentations, students develop practical skills while gaining a deeper understanding of how integrated systems enhance environmental resilience and scalability. As part of the School of the Environment’s broader sustainability initiatives, this activity emphasizes interdisciplinary approaches to tackling complex global challenges.
Aligned with the 4DEE framework, the activity incorporates Core Ecological Concepts (CEC), Ecology Practices (EP), Human-Environment Interactions (HEI), and Cross-Cutting Themes (CCT), creating a comprehensive educational experience. The FAMU SEED garden, serving as a living laboratory, fosters critical thinking, collaborative problem-solving, and systems-based learning. By engaging with this activity, students not only deepen their knowledge of sustainability but also explore innovative solutions for pressing challenges such as climate adaptation, food security, and resource efficiency, preparing them to become future leaders in sustainability science and practice.

description: Scheduling is a critical and challenging resource allocation mechanism for multihop wireless networks. It is well known that scheduling schemes that favor links with larger queue length can achieve high throughput performance. However, these queue-length-based schemes could potentially suffer from large (even infinite) packet delays due to the well-known last packet problem, whereby packets belonging to some flows may be excessively delayed due to lack of subsequent packet arrivals. Delay-based schemes have the potential to resolve this last packet problem by scheduling the link based on the delay the packet has encountered. However, characterizing throughput-optimality of these delay-based schemes has largely been an open problem in multihop wireless networks (except in limited cases where the traffic is single-hop.) In this paper, we investigate delay-based scheduling schemes for multihop traffic scenarios with fixed routes. We develop a scheduling scheme based on a new delay metric, and show that the proposed scheme achieves optimal throughput performance. Further, we conduct simulations to support our analytical results, and show that the delay-based scheduler successfully removes excessive packet delays, while it achieves the same throughput region as the queue-length-based scheme.

description: Energetic electrons of up to tens of MeV are created during explosive phenomena in the solar corona. While many theoretical models consider magnetic reconnection as a possible way of generating energetic electrons, the precise roles of magnetic reconnection during acceleration and heating of electrons still remain unclear. Here we show from 2D particle-in-cell simulations that coalescence of magnetic islands that naturally form as a consequence of tearing mode instability and associated magnetic reconnection leads to efficient energization of electrons. The key process is the secondary magnetic reconnection at the merging points, or the `anti-reconnection', which is, in a sense, driven by the converging outflows from the initial magnetic reconnection regions. By following the trajectories of the most energetic electrons, we found a variety of different acceleration mechanisms but the energization at the anti-reconnection is found to be the most important process. We discuss possible applications to the energetic electrons observed in the solar flares. We anticipate our results to be a starting point for more sophisticated models of particle acceleration during the explosive energy release phenomena.

Exploring the neurophysiological effect of aerobic exercise in concussion : an EEG feasibility study
Creators: name: O' Flaherty, Patrick
Publisher: name: University of British Columbia
Year: 2020

description: Concussion is a complex and dynamic injury that involves alterations in brain function. This can present clinically as post-concussive symptoms and exercise intolerance. However, functional brain changes can extend beyond the point of clinical recovery. This can lead to increased brain vulnerability when returning to play as complete physiological recovery has not yet been achieved. Neuroimaging techniques such as Electroencephalography (EEG) can quantify functional brain changes that are present after sustaining a concussion. Despite advances in neuroimaging techniques, there is a paucity of research evaluating the effect exercise has on brain function following a concussion. The aim of this feasibility study was to evaluate functional brain changes as measured by EEG spectral power in a group of concussed participants in comparison to healthy controls before and after performing a clinical exertion test entitled the Buffalo Concussion Bike Test (BCBT). A secondary aim was to evaluate behavioral differences between the two groups. The study consisted of five concussed and five control participants. Results revealed increased power in the 1-14 frequency range (delta, theta, alpha and low beta) in frontal brain regions of the concussed group in comparison to controls before and after performing the BCBT. EEG data collection was on average 90 to 120 minutes in duration and data quality was high for the majority of participants (83%). Three concussed participants failed the BCBT due to exceeding heart rate criteria, one failed due to symptom increase and one passed the test. Results indicate the feasibility of EEG spectral power as a measure of functional brain changes post-concussion, however the BCBT may not be a suitable concussion exertion protocol for a non-athlete population. For behavioral measures, we found clear group differences when comparing results between concussed and control groups.

description: Tea is a popular crop in Asia and Africa, yet only limited information on tea watershed hydrology is available. This study attempts to experimentally establish the rainfall partitioning parameters (RPPs), namely throughfall (TF), stemflow (SF), and rainfall interception (IC) for the 27-year-old tea plants grown in West Bengal, India. Relative proportion of TF, SF and IC varied respectively from 59-89%, 0.1-2%, and 10%-40% with respective CV as 10%, 29% and 27%. SF proportion being insignificant (≤2%) can be omitted. RPPs responses were also analyzed against rainfall depth (R), intensity, and duration. All RPPs showed an exponential decay with rainfall depth, except SF. The fitted/validated models were evaluated for the goodness of fit using error metrics/efficiency employing coefficient of determination, mean absolute error, root-mean-square error, and Nash-Sutcliffe efficiency. These results have pragmatic significance in tea watershed hydrology.

description: We examine the possibility that one could measure partonic charge symmetry violation (CSV) by comparing neutrino or antineutrino production through charged-current reactions induced by electrons or positrons at a possible electron collider at the LHC. We calculate the magnitude of CSV that might be expected at such a facility. We show that this is likely to be a several percent effect, substantially larger than the typical CSV effects expected for partonic reactions.

description: Purpose: The syndrome of inappropriate antidiuresis (SIAD) is the main cause of hyponatremia and the SGLT2-inhibitor empagliflozin is a promising new treatment option. A biomarker predicting treatment response could optimize treatment success. Materials and methods: Secondary analysis of a trial including 84 hospitalized patients with SIAD-induced hyponatremia. Patients were randomized to four days of treatment with empagliflozin 25mg/day (n = 43) or placebo (n = 41) with both groups receiving fluid restriction <1000ml/day. Baseline levels of copeptin, the natriuretic peptides MR-proANP and NT-proBNP and C-reactive protein (CRP) were evaluated as predictors for treatment response defined as absolute sodium change, using linear regression models. Additionally, urinary sodium was assessed as predictor for non-response to fluid restriction alone by constructing the receiver operating characteristic curve. Results: No clinically relevant predictive value for treatment response to empagliflozin could be found for copeptin, MR-proANP, NT-proBNP or CRP. A urinary sodium cutoff of >76mmol/l led to a specificity of 91.7% [95%-confidence-interval: 75%, 100%] and sensitivity of 51.9% [33.3%, 70.4%] to predict non-response to fluid restriction alone. Conclusions: Based on our data, no biomarker could be identified as predictor for treatment response to empagliflozin. Urinary sodium was confirmed as a good marker for non-response to fluid restriction in SIAD patients.

description: Given a finite-dimensional complex Lie algebra g equipped with a nondegenerate, symmetric, invariant bilinear form B, let V_k(g,B) denote the universal affine vertex algebra associated to g and B at level k. For any reductive group G of automorphisms of V_k(g,B), we show that the invariant subalgebra V_k(g,B)^G is strongly finitely generated for generic values of k. This implies the existence of a new family of deformable W-algebras W(g,B,G)_k which exist for all but finitely many values of k.

Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The transport of organelles and vesicles in living cells can be well described by a kinetic tug-of-war model advanced by Müller, Klumpp and Lipowsky. In which, the cargo is attached by two motor species, kinesin and dynein, and the direction of motion is determined by the number of motors which bind to the track. In recent work [Phys. Rev. E 79, 061918 (2009)], this model was studied by mean field theory, and it was found that, usually the tug-of-war model has one, two, or three distinct stable stationary points. However, the results there are mostly obtained by numerical calculations, since it is hard to do detailed theoretical studies to a two-dimensional nonlinear system. In this paper, we will carry out further detailed analysis about this model, and try to find more properties theoretically. Firstly, the tug-of-war model is simplified to a one-dimensional equation. Then we claim that the stationary points of the tug-of-war model correspond to the roots of the simplified equation, and the stable stationary points correspond to the roots with positive derivative. Bifurcation occurs at the corresponding parameters, under which the simplified one-dimensional equation exists root with zero derivative. Using the simplified equation, not only more properties of the tug-of-war model can be obtained analytically, the related numerical calculations will become more accurate and more efficient. This simplification will be helpful to future studies of the tug-of-war model.

description: Suppose $X$ is a hyperelliptic curve of genus $g$ defined over an algebraically closed field $k$ of characteristic $p=2$. We prove that the de Rham cohomology of $X$ decomposes into pieces indexed by the branch points of the hyperelliptic cover. This allows us to compute the isomorphism class of the $2$-torsion group scheme $J_X[2]$ of the Jacobian of $X$ in terms of the Ekedahl-Oort type. The interesting feature is that $J_X[2]$ depends only on some discrete invariants of $X$, namely, on the ramification invariants associated with the branch points. We give a complete classification of the group schemes which occur as the $2$-torsion group schemes of Jacobians of hyperelliptic $k$-curves of arbitrary genus.

description: This paper studies the existence of invariant smooth Lagrangian graphs for Tonelli Hamiltonian systems with symmetries. In particular, we consider Tonelli Hamiltonians with n independent but not necessarily involutive constants of motion and obtain two theorems reminiscent of the Liouville-Arnold theorem. Moreover, we also obtain results on the structure of the configuration spaces of such systems that are reminiscent of results on the configuration space of completely integrable Tonelli Hamiltonians.

description: State preparation, qubit rotation, and high fidelity readout are demonstrated for two separate \baseven qubit types. First, an optical qubit on the narrow 6S$_{1/2}$ to 5D$_{5/2}$ transition at 1.76 $μ$m is implemented. Then, leveraging the techniques developed there for readout, a ground state hyperfine qubit using the magnetically insensitive transition at 8 GHz is accomplished.

description: Of concern in the paper is a study of steady incompressible viscoelastic and electrically conducting fluid flow and heat transfer in a parallel plate channel with stretching walls in the presence of a magnetic field applied externally. The flow is considered to be governed by Walter's liquid B fluid. The problem is solved by developing a suitable numerical method. The results are found to be in good agrement with those of earlier investigations reported in existing scientific literatures. The study reveals that a back flow occurs near the central line of the channel due to the stretching walls and further that this flow reversal can be stopped by applying a strong external magnetic field. The study also shows that with the increase in the strength of the magnetic field, the fluid velocity decreases but the temperature increases. Thus the study bears potential applications in the study of the haemodynamic flow of blood in the cardiovascular system when subjected to an external magnetic field.

description: We study various walk models on the complete graph and the full m-ary tree. In particular, we study the mean and variance asymptotics of these models, as well as the weak limits. We study these properties for a sequence of fugacities; a parameter used when studying variable-length ensembles to represent the distribution weight. While some results on finite graphs are already established, we observed a critical window for fugacities that converge quickly enough to the critical point, and a scaling window which smoothly links the critical and non-critical regions. These critical and scaling windows are established for the mean and variance asymptotics. We also show universality between weakly self-avoiding walks and self-avoiding walks on the complete graph.

description: In this work we consider infinite dimensional extensions of some finite dimensional Gaussian geometric functionals called the Gaussian Minkowski functionals. These functionals appear as coefficients in the probability content of a tube around a convex set $D\subset\mathbb{R}^k$ under the standard Gaussian law $N(0,I_{k\times k})$. Using these infinite dimensional extensions, we consider geometric properties of some smooth random fields in the spirit of [Random Fields and Geometry (2007) Springer] that can be expressed in terms of reasonably smooth Wiener functionals.

Interpolation, growth conditions, and stochastic gradient descent
Creators: name: Mishkin, Aaron
Publisher: name: University of British Columbia
Year: 2020

description: Current machine learning practice requires solving huge-scale empirical risk minimization problems quickly and robustly. These problems are often highly under-determined and admit multiple solutions which exactly fit, or interpolate, the training data. In such cases, stochastic gradient descent has been shown to converge without decreasing step-sizes or averaging, and can achieve the fast convergence of deterministic gradient methods. Recent work has further shown that stochastic acceleration and line-search methods for step-size selection are possible in this restricted setting. Although pioneering, existing analyses for first-order methods under interpolation have two major weaknesses: they are restricted to the finite-sum setting, and, secondly, they are not tight with the best deterministic rates. To address these issues, we extend the notion of interpolation to stochastic optimization problems with general, first-order oracles. We use the proposed framework to analyze stochastic gradient descent with a fixed step-size and with an Armijo-type line-search, as well as Nesterov’s accelerated gradient method with stochastic gradients. In nearly all settings, we obtain faster convergence with a wider range of parameters. The improvement for stochastic Nesterov acceleration is comparable to dividing by the square-root of the condition number and addresses criticism that existing rates were not truly “accelerated”. In the case of convex functions, our convergence rates for stochastic gradient descent — both with and without the stochastic Armijo line-search — recover the best-known rates in the deterministic setting. We also provide a simple extension to L2-regularized minimization, which opens the path to proximal-gradient methods and non-smooth optimization under interpolation.

description: The Casimir force between two infinitely thin parallel sheets in a setting of $N$ such sheets is found. The finite two-dimensional conductivities, which describe the dispersive and absorptive properties of each sheet, are taken into account, whereupon the theory is applied to interacting graphenes. By exploring similarities with in-plane optical spectra for graphite, the conductivity of graphene is modeled as a combination of Lorentz type oscillators. We find that the graphene transparency and the existence of a universal constant conductivity $e^2/(4\hbar)$ result in graphene/graphene Casimir interaction at large separations to have the same distance dependence as the one for perfect conductors but with much smaller magnitude.

DROP CITY FEST Drum and Bass: una cultura musicale di nicchia

description: Che serata c’è stasera a Varese? Questa domanda è sempre stata parte della mia adolescenza e lo è tutt’oggi. Ebbene sì, la mia idea di tesi parte proprio da qui, chiedendomi dove potessi andare ad ascoltare musica Drum and Bass a Varese, la città in cui vivo. E tu la conosci questa musica? La Drum and Bass non è altro che un genere di musica elettronico, poco conosciuto in Italia, caratterizzato da un ritmo veloce ed energico. Non è la classica musica che puoi ballare nelle discoteche o che canti a squarciagola mentre guidi. La Drum and Bass è un genere che devi seguire, scoprire e di cui ti devi appropriare, fino a non lasciarla più. Non parliamo solo del tipico “tunz tunz tunz”, con la D’n’B andiamo ben oltre, anche se spesso è vittima di pregiudizio e non accettata dalle masse, in realtà dietro di sé nasconde un vero e proprio stile di vita. Chi ascolta questa musica lo fa con il cuore e non solo per fare festa e sballarsi, ma ciò che interessa è lasciarsi andare sotto le note del mondo Drum and Bass. Tutto ciò non è presente a Varese, poiché non vengono organizzati eventi musicali Drum and Bass a causa della sua poca diffusione. Nonostante la zona si presti molto bene a festival ed eventi culturali, chi vuole fare una serata 100% D’n’B, deve andare fuori città. Nasce da qui la mia volontà di dare un volto a questa musica, esaltare i suoi valori e far scoprire qualcosa in più alle persone. -Cambiare la routine varesina? Perché no!- L’intento è proporre qualcosa di diverso dal solito, coinvolgere le persone e la città di Varese nella community Drum and Bass. Offrire un nuovo servizio sul territorio, per accontentare gli appassionati e incuriosire quelli futuri.
Bilayer graphene with single and multiple electrostatic barriers: band structure and transmission

description: We evaluate the electronic transmission and conductance in bilayer graphene through a finite number of potential barriers. Further, we evaluate the dispersion relation in a bilayer graphene superlattice with a periodic potential applied to both layers. As a model we use the tight-binding Hamiltonian in the continuum approxi- mation. For zero bias the dispersion relation shows a finite gap for carriers with zero momentum in the direction parallel to the barriers. This is in contrast to single-layer graphene where no such gap was found. A gap also appears for a finite bias. Numerical results for the energy spectrum, conductance, and the density of states are presented and contrasted with those pertaining to single-layer graphene.

Reading mathematics: a textbook approach

description: Mathematics textbooks have always been a staple of mathematics classrooms around the world. Furthermore, despite the digital age and the ever-increasing amount of online resources, mathematical textbooks have endured. In recent years, research into mathematics textbooks has increased to reflect this; however, research into how students use their mathematics textbooks remains limited. In this thesis, I investigate how students use their mathematics textbooks, situating this with the practical aspect of textbook research, i.e., how are textbooks designed to be read? My PhD studentship involved a collaboration with Oxford University Press so practical considerations for my research are woven throughout the thesis, including the use of real-world materials. As such, my findings contribute to conversations in the publishing world as well as the research literature. I split the thesis into two parts. In the first part, I interviewed students and textbook authors to understand how students use their textbooks and how the publishing company expects them to. Illuminating this relationship enabled me to review the efficacy of students’ textbook use and whether they used their textbooks as intended. I found that some textbook features might not encourage beneficial learning strategies and that more students used the exposition than expected. As such, I focused on the exposition in the second part of this thesis. Indeed, I started the second part by investigating the characteristics of expositions using comparative judgement. Not only did I find that comparative judgement appears to be an appropriate measure of exposition quality, but I found several characteristics of mathematical texts which appear to affect its quality. I followed these findings up with two final empirical studies, using eyetracking technology and comparative judgement again. I found that presenting text or pictures in the margin affects how students read them, and that exposition quality could be improved by highlighting key text. My findings identify various avenues of future work. In particular, the importance of finding a relatively straightforward and low-cost approach to support publishers and help improve mathematical textbook expositions using research-based evidence.
