description: We are interested in the long-time behaviour of approximate solutions to heterogeneous and anisotropic linear advection-diffusion equations in the framework of hybrid finite volume (HFV) methods on general polygonal/polyhedral meshes. We consider two linear methods, as well as a new, nonlinear scheme, for which we prove the existence and the positivity of discrete solutions. We show that the discrete solutions to the three schemes converge exponentially fast in time towards the associated discrete steady-states. To illustrate our theoretical findings, we present some numerical simulations assessing long-time behaviour and positivity. We also compare the accuracy of the schemes on some numerical tests in the stationary case.

description: Studies show that the intention of students at Swiss universities to become an entrepreneur has been showing a positive trend since 2013 resulting in a 18,8 percent rate in 2021. The first part of this paper documents the analysis of how the business faculties of the nine Universities of Applied Sciences belonging to the Swissuniversities Association take up the topic of entrepreneurship in their Bachelor- and Master-degree programs. This part is based on an analysis of publicly accessible module descriptions of the business administration curricula. The results show that three patterns can be recognized. Firstly, a group of universities that explicitly take up entrepreneurship as a focus subject in their curricula. Secondly, a group that deals with the topic in conjunction with the topic of "innovation". And thirdly, a group of universities that do not address the topic at all in their curricula. The second part presents the case study of the "Entrepreneurship Pyramid" which is an Integrated Concept implemented at the School of Business of the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) which belongs to the first group of universities mentioned above. The concept divides the entrepreneurship education into four levels. At the lowest level, there are compulsory courses for all students in the bachelor's degree programs. The next two levels are optional specializations in bachelor's and master's courses, the latter of which can already lead to founding a company. On the fourth level, there are other, mostly post-graduate offers. For this purpose, the School of Business of FHNW has built up a network within a regional ecosystem, which supports graduates in their entrepreneurial activities even after completing their studies. Start-up competitions, financing and coaching are offered in cooperation with state institutions, associations, and private companies. This part includes the results of a study which analysed how large the number of startups founded by graduates from the School of Business of FHNW is.

description: Precision measurements of $β$-decay observables offer the possibility to search for deviations from the Standard Model. A possible discovery of such deviations requires accompanying first-principles calculations. Here we compute the nuclear structure corrections for the $β$-decay of $^6$He which is of central interest in several experimental efforts. We employ the impulse approximation together with wave functions calculated using the ab initio no-core shell model with potentials based on chiral effective field theory. We use these state-of-the-art calculations to give a novel and comprehensive analysis of theoretical uncertainties. We find that nuclear corrections, which we compute within the sensitivity of future experiments, create significant deviation from the naive Gamow-Teller predictions, making their accurate assessment essential in searches for physics beyond the Standard Model.

description: We utilize the concept of a measurement-induced entanglement transition to analyze the interplay and competition of processes that generate and destroy entanglement in a one-dimensional quantum spin chain evolving under a locally noisy and disordered Hamiltonian. We employ continuous measurements of variable strength to induce a transition from volume to area-law scaling of the steady-state entanglement entropy. While static background disorder systematically reduces the critical measurement strength, this critical value depends non-monotonically on the strength of non-static noise. According to the extracted fine-size scaling exponents, the universality class of the transition is independent of the noise and disorder strength. We interpret the results in terms of the effect of static and non-static disorder on the intricate dynamics of the entanglement generation rate due to the Hamiltonian in the absence of measurement, which is fully reflected in the behavior of the critical measurement strength. Our results establish a firm connection between this entanglement growth and the steady-state behavior of the measurement-controlled systems, which therefore can serve as a tool to quantify and investigate features of transient entanglement dynamics in complex many-body systems via a steady-state phase transition.

description: This paper argues that, insofar as we doubt the bivalence of the Continuum Hypothesis or the truth of the Axiom of Choice, we should also doubt the consistency of third-order arithmetic, both the classical and intuitionistic versions. Underlying this argument is the following philosophical view. Mathematical belief springs from certain intuitions, each of which can be either accepted or doubted in its entirety, but not half-accepted. Therefore, our beliefs about reality, bivalence, choice and consistency should all be aligned.

description: L'intervento intende illustrare le recenti strategie dell'ICCU per rendere sempre più aperti e riutilizzabili i dati delle biblioteche, in modo da poterli integrare nel web e con le infrastrutture per la ricerca che si stanno realizzando in Italia e all’estero.
A partire dalla politica di apertura di SBN, ora in grado di integrare al suo interno materiali di tipo diverso e differenti programmi, viene affrontato il tema dal punto di vista dei servizi di prestito interbibliotecario che rappresenta attualmente un obiettivo prioritario per l'ICCU.
Un altro passo verso tale obiettivo è stato fatto con la condivisione delle informazioni sui dati anagrafici delle biblioteche censite nell’Anagrafe delle biblioteche italiane pubblicati sotto forma di open data con licenza Creative Commons.
Anche sul Portale CulturaItalia viene gradualmente implementata una sezione specifica dedicata ai Linked Open Data.
In ambito europeo l’ICCU partecipa allo sviluppo di alcune delle più importanti infrastrutture per la conoscenza e la ricerca nel settore del patrimonio culturale e delle Digital Humanities, come DARIAH e PARTHENOS svolgendo un ruolo di primo piano nel coordinamento dei processi di aggregazione dei dati e nell’elaborazione di policies e linee guida per lo sviluppo degli open data e dell’open access, analizzando le problematiche legate al diritto d’autore nel contesto normativo nazionale ed europeo.

description: The S=3/2 Kitaev honeycomb model (KHM) is a quantum spin liquid (QSL) state coupled to a static Z$_2$ gauge field. Employing an SO(6) Majorana representation of spin 3/2's, we find an exact representation of the conserved plaquette fluxes in terms of static Z$_2$ gauge fields akin to the S=1/2 KHM which enables us to treat the remaining interacting matter fermion sector in a parton mean-field theory. We uncover a ground-state phase diagram consisting of gapped and gapless QSLs. Our parton description is in quantitative agreement with numerical simulations, and is furthermore corroborated by the addition of a $[001]$ single ion anisotropy (SIA) which continuously connects the gapless Dirac QSL of our model with that of the S=1/2 KHM. In the presence of a weak $[111]$ SIA, we discuss an emergent chiral QSL within a perturbation theory.

description: The quest to understand consciousness, once the purview of philosophers and theologians, is now actively pursued by scientists of many stripes. We examine consciousness from the perspective of theoretical computer science (TCS), a branch of mathematics concerned with understanding the underlying principles of computation and complexity, including the implications and surprising consequences of resource limitations. In the spirit of Alan Turing's simple yet powerful definition of a computer, the Turing Machine (TM), and perspective of computational complexity theory, we formalize a modified version of the Global Workspace Theory (GWT) of consciousness originated by cognitive neuroscientist Bernard Baars and further developed by him, Stanislas Dehaene, Jean-Pierre Changeaux and others. We are not looking for a complex model of the brain nor of cognition, but for a simple computational model of (the admittedly complex concept of) consciousness. We do this by defining the Conscious Turing Machine (CTM), also called a conscious AI, and then we define consciousness and related notions in the CTM. While these are only mathematical (TCS) definitions, we suggest why the CTM has the feeling of consciousness. The TCS perspective provides a simple formal framework to employ tools from computational complexity theory and machine learning to help us understand consciousness and related concepts. Previously we explored high level explanations for the feelings of pain and pleasure in the CTM. Here we consider three examples related to vision (blindsight, inattentional blindness, and change blindness), followed by discussions of dreams, free will, and altered states of consciousness.

description: Electro-optic modulators from non-linear $χ^{(2)}$ materials are essential for sensing, metrology and telecommunications because they link the optical domain with the microwave domain. At present, most geometries are suited for fiber applications. In contrast, architectures that modulate directly free-space light at gigahertz (GHz) speeds have remained very challenging, despite their dire need for active free-space optics, in diffractive computing or for optoelectronic feedback to free-space emitters. They are typically bulky or suffer from much reduced interaction lengths. Here, we employ an ultrathin array of sub-wavelength Mie resonators that support quasi bound states in the continuum (BIC) as a key mechanism to demonstrate electro-optic modulation of free-space light with high efficiency at GHz speeds. Our geometry relies on hybrid silicon-organic nanostructures that feature low loss ($Q = $ 550 at $λ_{res} = 1594$ nm) while being integrated with GHz-compatible coplanar waveguides. We maximize the electro-optic effect by using high-performance electro-optic molecules (whose electro-optic tensor we engineer in-device to exploit $r_{33} = 100$ pm/V) and by nanoscale optimization of the optical modes. We demonstrate both DC tuning and high speed modulation up to 5~GHz ($f_{EO,-3 dB} =3$ GHz) and shift the resonant frequency of the quasi-BIC by $Δλ_{res}=$11 nm, surpassing its linewidth. We contrast the properties of quasi-BIC modulators by studying also guided mode resonances that we tune by $Δλ_{res}=$20 nm. Our approach showcases the potential for ultrathin GHz-speed free-space electro-optic modulators.

 Introduction: The number of confirmed cases during the current Covid-19 pandemic is escalating exponentially. At the same time, the public are constantly being inundated with a formidable quantity of information, from innumerable sources, and containing both genuine as well as fake news. The Covid-19 “infodemic” is here. Health professionals including medical doctors and nurses are busy fighting the virus on the front line in our communities and hospitals and struggling to treat the ever-growing number of cases. Scientists and technicians at their bench-tops and computers in their research laboratories, are racing to find solutions, create new protective equipment, and ideally develop a vaccine. They all need accurate, timely and reliable information upon which they can make their decisions, find solutions, and help defeat this pandemic. This initiative aims to provide reliable and timely (initially at least twice a week) web updates on the relevant published literature. “Reliable” and “timely” means that it can be trusted and it is up to date; “relevant” and “published” means that it is focused on what health professionals and scientists need when facing both the pandemic and the infodemic, and it can be trusted as sound science. We plan to make the material succinct and accessible, and to provide key bibliometric indices such as source and citation.
 Objectives: 1. To update the global scientific community on current Covid-19 related published papers in an accessible, timely and trusted format
 2. To analyse the published papers for trends and to provide insights
 3. To identify gaps in research
 4. To promote international research collaboration with a view to overcoming Covid-19 and promoting recovery Methodology:  Covid-19 related publications to be searched using the Scopus database using as a minimum the following keywords: 2019-nCoV, SARS-CoV-2, Covid-19, novel Coronavirus. Papers then to be categorized according to topic, research fields, institutions, countries, etc. Abstracts and papers to be reviewed for findings, trends, key insights, etc. To read previous COVID-19 research insights, please go to:

description: The BV-Laplacian $Δ$ in quantum field theory is singular, by construction, but can be regularized by deforming the classical BV-action. Taking inspiration from string theory we describe a non-local deformation of the latter by adding stubs to the interaction vertices while keeping classical BV-invariance manifest. This is achieved using a version of homotopy transfer resulting in a non-polynomial action for which the quantum master equation is now well defined and will be satisfied by adding additional vertices at loop level. The latter can be defined with the help of standard regularization schemes and is independent of the definition of $Δ$. In particular, the determination of anomalies reduces to the standard text-book calculation. Finally, we describe how the deformed (quantum) action can be obtained as a canonical transformation. As an example, we illustrate this procedure for quantum electrodynamics.

description: Predictive process monitoring aims at forecasting the behavior, performance, and outcomes of business processes at runtime. It helps identify problems before they occur and re-allocate resources before they are wasted. Although deep learning (DL) has yielded breakthroughs, most existing approaches build on classical machine learning (ML) techniques, particularly when it comes to outcome-oriented predictive process monitoring. This circumstance reflects a lack of understanding about which event log properties facilitate the use of DL techniques. To address this gap, the authors compared the performance of DL (i.e., simple feedforward Deep Neural Networks and Long Short Term Memory Networks) and ML tech-niques (i.e., Random Forests and Support Vector Machines) based on five publicly available event logs. It could be observed that DL generally outperforms classical ML techniques. Moreover, three specific propositions could be inferred from further observations: First, the outperformance of DL techniques is particularly strong for logs with a high variant-to-instance ratio (i.e., many non-standard cases). Sec-ond, DL techniques perform more stably in case of imbalanced target variables, especially for logs with a high event-to-activity ratio (i.e., many loops in the control flow). Third, logs with a high activity-to-instance payload ratio (i.e., input data is predominantly generated at runtime) call for the application of Long Short Term Memory Networks. Due to the purposive sampling of event logs and techniques, these findings also hold for logs outside this study.

description: Significant leaps in the understanding of quantum systems have been driven by the exploration of geometry, topology, dimensionality, and interactions with ultracold atomic ensembles. A system where atoms evolve while confined on an ellipsoidal surface represents a heretofore unexplored geometry and topology. Realizing such an ultracold bubble system (potentially Bose-Einstein condensed) has areas of interest including quantized-vortex flow respecting topological constraints imposed by closed surfaces, new collective modes, and self-interference via free bubble expansion. Large ultracold bubbles, created by inflating smaller condensates, directly tie into Hubble-analog expansion physics. Here, we report observations from the NASA Cold Atom Lab facility aboard the International Space Station of bubbles of ultracold atoms created using a radiofrequency-dressing protocol. We observe a variety of bubble configurations of differing sizes and initial temperature, and explore bubble thermodynamics, demonstrating significant cooling associated with inflation. Additionally, we achieve partial coverings of bubble traps greater than 1 mm in size with ultracold films of inferred few-$μ$m thickness, and we observe the dynamics of shell structures projected into free-evolving harmonic confinement. The observations are part of the first generation of scientific measurements made with ultracold atoms in space, exploiting the benefits of perpetual free-fall to explore gravity-free evolution of quantum systems that are prohibitively difficult to create on Earth. This work points the way to experiments focused on the nature of the Bose-Einstein condensed bubble, the character of its excitations, and the role of topology in its evolution; it also ushers in an era of orbital microgravity quantum-gas physics.

description: We construct a Weyl transverse diffeomorphism invariant theory of symmetric teleparallel gravity by employing the Weyl compensator formalism. The low-energy dynamics has a single spin two gravition without a scalar degree of freedom. By construction, it is equivalent to the unimodular gravity (as well as the Einstein gravity) at the non-linear level.

description: Fluctuation theorems specify the non-zero probability to observe negative entropy production, contrary to a naive expectation from the second law of thermodynamics. For closed particle trajectories in a fluid, Stokes theorem can be used to give a geometric characterization of the entropy production. Building on this picture, we formulate a topological fluctuation theorem that depends only by the winding number around each vortex core and is insensitive to other aspects of the force. The probability is robust to local deformations of the particle trajectory, reminiscent of topologically protected modes in various classical and quantum systems. We demonstrate that entropy production is quantized in these strongly fluctuating systems, and it is controlled by a topological invariant. We demonstrate that the theorem holds even when the probability distributions are non-Gaussian functions of the generated heat.

description: Attrition in higher education at master level is a remarkable issue in higher education in Cambodia, which have to be studied. Such students would face social disappointments, academic dissatisfactions, and economic disadvantages. In this study, there are one main objective and two sub-objectives. The main objective is to ascertain the perspectives of the attrition of the master candidates. Moreover, the first of the two sub-objectives is to determine difficulties faced by students who left the program. The second is to gather feedback from the leavers to inform policy makers on how to ensure more student retention. In-depth interview and participant observation were used to collect the data. 8 former master’s students were interviewed. Master’s program director was also interviewed. In addition, other 4 former master’s students were observed. Thematic analysis was employed to analyze the data. The 4 main themes in the leavers’ stories were personal attitudes, student mobility, integration (social and academic), and external factors. The finding revealed that most of the reasons that cause the attrition were from the students’ side rather than from the program’s side. The leading conclusion was that the master candidates have to manage better time management in order to survive in graduate school.

description: Nonlinearity is a powerful determinant of physical systems. Controlling nonlinearity leads to interesting states of matter and new applications. In optics, diverse families of continuous and discrete states arise from balance of nonlinearity and group-velocity dispersion (GVD). Moreover, the dichotomy of states with locally enhanced or diminished field intensity depends critically on the relative sign of nonlinearity and either anomalous or normal GVD. Here, we introduce a resonator with unconditionally normal GVD and a single defect mode that supports both dark, reduced-intensity states and bright, enhanced-intensity states. We access and explore this dark-to-bright pulse continuum by phase-matching for soliton generation with a photonic-crystal resonator, which mediates the competition of nonlinearity and normal GVD. These stationary temporal states are coherent frequency combs, featuring highly designable spectra and ultralow noise repetition-frequency and intensity characteristics. The dark-to-bright continuum illuminates physical roles of Kerr nonlinearity, GVD, and laser propagation in a gapped nanophotonic medium.
