description: Η παρούσα διπλωματική εργασία επιχειρεί την ανάπλαση του παραλιακού μετώπου της πόλης Σκάλας Ωρωπού. Ο δήμος Ωρωπού βρίσκεται στην Βορειοανατολική Αττική και εκτείνεται από τον Ευβοϊκό κόλπο έως τους πρόποδες της Πάρνηθας. Στην ευρύτερη περιοχή ξεχωρίζει η παρουσία του έντονου ανάγλυφου, η πυκνή και άναρχη βλάστηση καθώς και η ήπια αμφιθεατρική διάταξη της τοποθεσίας. Ο στόχος της διπλωματικής είναι να επιλύσει τις προβληματικές χωρικές σχέσεις μεταξύ πόλης και παραλιακού μετώπου, εξαιτίας του οδικού δικτύου που διαπερνά και διαιρεί την περιοχή.  Η παρέμβαση αφορά στον σχεδιασμό τριών παράλληλων ζωνών, δηλαδή της αστικής ζώνης, της ενδιάμεσης και της ζώνης γειτνίασης με το νερό, καθώς και στην ενδυνάμωση των εγκάρσιων συνδέσεων. Μελετώνται χώροι στάσης και αρχιτεκτονικές κατασκευές μικρής κλίμακας,  όπου σε συνάρτηση με το πράσινο θα αποτελέσουν συνδετικό κρίκο των παραπάνω περιοχών και θα συμβάλλουν στην ανάκτηση του δημόσιου χώρου.

description: The goal of inverse problems is to find an unknown parameter based on noisy data. Such problems appear in a wide range of applications including geophysics, medicine, and chemistry. One method of solving them is known as the Bayesian approach. In this approach, the unknown parameter is modelled as a random variable to reflect its uncertain value. Bayes’ theorem is applied to update our knowledge given new information from noisy data.

A uniqueness criterion and a counterexample to regularity in an incompressible variational problem

description: In this paper we consider the problem of minimizing functionals of the form $E(u)=\int_B f(x,\nabla u) \,dx$ in a suitably prepared class of incompressible, planar maps $u: B \rightarrow \mathbb{R}^2$. Here, $B$ is the unit disk and $f(x,ξ)$ is quadratic and convex in $ξ$. It is shown that if $u$ is a stationary point of $E$ in a sense that is made clear in the paper, then $u$ is a unique global minimizer of $E(u)$ provided the gradient of the corresponding pressure satisfies a suitable smallness condition. We apply this result to construct a non-autonomous, uniformly convex functional $f(x,ξ)$, depending smoothly on $ξ$ but discontinuously on $x$, whose unique global minimizer is the so-called $N-$covering map, which is Lipschitz but not $C^1$.

Small scale structure of spacetime: van Vleck determinant and equi-geodesic surfaces

description: It has recently been argued that if spacetime $\mathcal M$ possesses non-trivial structure at small scales, an appropriate semi-classical description of it should be based on non-local bi-tensors instead of local tensors such as the metric $g_{ab}$. Two most relevant bi-tensors in this context are Synge's World function $Ω(p,p_0)$ and the van Vleck determinant (VVD) $Δ(p,p_0)$, as they encode the metric properties of spacetime and (de)focussing behaviour of geodesics. They also characterize the leading short distance behavior of two point functions of the d'Alembartian $_{p_0} \square_p$. We begin by discussing the intrinsic and extrinsic geometry of equi-geodesic surfaces $Σ_{G,p_0}$ defined by $Ω(p,p_0)=constant$ in a geodesically convex neighbourhood of an event $p_0$, and highlight some elementary identities relating the VVD with geometry of these surfaces. As an aside, we also comment on the contribution of $Σ_{G,p_0}$ to the surface term in the Einstein-Hilbert (EH) action and show that it can be written as a volume integral of $\square \ln Δ$. We then study the small scale structure of spacetime in presence of a Lorentz invariant short distance cut-off $\ell_0$ using $Ω$ and $Δ$, based on some recently developed ideas. We derive a 2nd rank bi-tensor $q_{ab}$ which naturally yields geodesic intervals bounded from below, and present a general and mathematically rigorous analysis of short distance structure of spacetime based on (a) geometry of $Σ_{G,p_0}$, (b) structure of the non local d'Alembartian associated with $q_{ab}$, and (c) properties of the VVD. In particular, we show that the Ricci bi-scalar of $q_{ab}$ is completely determined by $Σ_{G,p_0}$, the tidal tensor, and first two derivatives of the van Vleck determinant, and has a non-trivial "classical" limit given by (constant) $R_{ab} q^a q^b$ (see text).

Cross-country variation in educational attainment: structural change or within-industry skill upgrading?
Creators: name: Hendricks, Lutz
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Educational attainment varies greatly across countries and within countries over time. This paper asks whether the variation in education is primarily due to industry composition or to within industry skill intensities. The main finding is that within industry variation accounts for at least two-thirds of the cross-country and the time series variation in educational attainment. The within industry education gaps are broadly consistent with a model of industry neutral cross-country differences in skilled labor productivity. These results suggest that theories of educational development should focus on skill upgrading within industries rather than structural change.
Dynamic Power Splitting Policies for AF Relay Networks with Wireless Energy Harvesting

description: Wireless energy harvesting (WEH) provides an exciting way to supply energy for relay nodes to forward information for the source-destination pairs. In this paper, we investigate the problem on how the relay node dynamically adjusts the power splitting ratio of information transmission (IT) and energy harvesting (EH) in order to achieve the optimal outage performance. According to the knowledge of channel state information (CSI) at the relay, optimal dynamic power splitting policy with full CSI and partial CSI are both provided. Finally, through simulations, the proposed power splitting policies can improve the outage performances and the policy with full CSI achieves the best performance. It is also shown that the policy with partial CSI can approach the policy with full CSI closely and incurs far less system overhead.

Equilibrium statistical mechanics and energy partition for the shallow water model

description: The aim of this paper is to use large deviation theory in order to compute the entropy of macrostates for the microcanonical measure of the shallow water system. The main prediction of this full statistical mechanics computation is the energy partition between a large scale vortical flow and small scale fluctuations related to inertia-gravity waves. We introduce for that purpose a discretized model of the continuous shallow water system, and compute the corresponding statistical equilibria. We argue that microcanonical equilibrium states of the discretized model in the continuous limit are equilibrium states of the actual shallow water system. We show that the presence of small scale fluctuations selects a subclass of equilibria among the states that were previously computed by phenomenological approaches that were neglecting such fluctuations. In the limit of weak height fluctuations, the equilibrium state can be interpreted as two subsystems in thermal contact: one subsystem corresponds to the large scale vortical flow, the other subsystem corresponds to small scale height and velocity fluctuations. It is shown that either a non-zero circulation or rotation and bottom topography are required to sustain a non-zero large scale flow at equilibrium. Explicit computation of the equilibria and their energy partition is presented in the quasi-geostrophic limit for the energy-enstrophy ensemble. The possible role of small scale dissipation and shocks is discussed. A geophysical application to the Zapiola anticyclone is presented.

description: This paper unifiedly addresses two kinds of key quantum secure tasks, i.e., quantum versions of secret sharing (SS) and symmetric private information retrieval (SPIR) by using multi-target monotone span program (MMSP), which characterizes the classical linear protocols of SS and SPIR. SS has two quantum extensions; One is the classical-quantum (CQ) setting, in which the secret to be sent is classical information and the shares are quantum systems. The other is the quantum-quantum (QQ) setting, in which the secret to be sent is a quantum state and the shares are quantum systems. The relation between these quantum protocols and MMSP has not been studied sufficiently. We newly introduce the third setting, i.e., the entanglement-assisted (EA) setting, which is defined by modifying the CQ setting with allowing prior entanglement between the dealer and the end-user who recovers the secret by collecting the shares. Showing that the linear version of SS with the EA setting is directly linked to MMSP, we characterize linear quantum versions of SS with the CQ ad QQ settings via MMSP. Further, we introduce the EA setting of SPIR, which is shown to link to MMSP. In addition, we discuss the quantum version of maximum distance separable codes.
Approximate cores of games and economies with clubs

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: We introduce the framework of parameterized collections of games with and without sidepayments and provide three nonemptiness of approximate core theorems for games in parameterized collections. The parameters bound (a) the number of approximate types of players and the size of the approximation and (b) the size of nearly effective groups of players and their distance from exact effectiveness. The theorems are based on a new notion of partition-balanced profiles and approximately partition-balanced profiles. The results are applied to a new model of an economy with clubs. In contrast to the extant literature, our approach allows both widespread externalities and uniform results.
Critical Evaluation of the Provisions of CEN/TR 1993-1-103 Regarding Buckling Length of Steel Members
Creators: name: Taliadouros, Leonidas
Publisher: name: Zenodo
Year: 2022

description: The advancement of technology of the building materials through the development of new methods of production and processing, makes it possible to create members with almost any geometry and shape, as well as thickness, which, in combination with the introduction of finite element analysis software, led in the use of increasingly thin members and constructions, which are subsequently sensitive to different forms of buckling. The set of methods for calculating the critical buckling loads for the different forms of manifestation of geometry nonlinearity are not analyzed in the design methods of Eurocode 3, but are described in detail in the provisions of the new CEN/TR 1993-1-103. The object of this thesis is the creation of appropriate applications of the individual chapters of the standard, in order to evaluate their reliability, but also the coexistence with the corresponding design methods of ΕΝ1993-1-103. The selection of the various examples is also intended to highlight cases of particular interest and several uncertainties. More specifically, it is to be studied, the flexural buckling of a cantilever of non-uniform section under compression, the buckling of the upper chord of steel truss bridge, a mono-symmetrical cross-section of single symmetry under compression which undergoes torsional-flexural buckling, a second mono-symmetrical cross-section under bending that manifest lateral buckling, but also the stiffness value required, for an elastic constraint, to be considered fixed. In addition, both the theoretical background and the application method of the single local and global imperfection in the shape of elastic critical buckling model (UGLI) have been analyzed, which seems to be the most effective way to universally treat the imperfections in most of the cases of structural steel members. Lastly, it is worth noting that a key ally during the completion of this diploma thesis was the set of non-linear analysis, which provided necessary information both for the behavior and the strength of the various members and structures. Consequently, at the end of each chapter, one can tell whether it is necessary to apply non-linear to the individual examples.
Do they agree? Bibliometric evaluation vs informed peer review in the Italian research assessment exercise

description: During the Italian research assessment exercise, the national agency ANVUR performed an experiment to assess agreement between grades attributed to journal articles by informed peer review (IR) and by bibliometrics. A sample of articles was evaluated by using both methods and agreement was analyzed by weighted Cohen's kappas. ANVUR presented results as indicating an overall 'good' or 'more than adequate' agreement. This paper re-examines the experiment results according to the available statistical guidelines for interpreting kappa values, by showing that the degree of agreement, always in the range 0.09-0.42 has to be interpreted, for all research fields, as unacceptable, poor or, in a few cases, as, at most, fair. The only notable exception, confirmed also by a statistical meta-analysis, was a moderate agreement for economics and statistics (Area 13) and its sub-fields. We show that the experiment protocol adopted in Area 13 was substantially modified with respect to all the other research fields, to the point that results for economics and statistics have to be considered as fatally flawed. The evidence of a poor agreement supports the conclusion that IR and bibliometrics do not produce similar results, and that the adoption of both methods in the Italian research assessment possibly introduced systematic and unknown biases in its final results. The conclusion reached by ANVUR must be reversed: the available evidence does not justify at all the joint use of IR and bibliometrics within the same research assessment exercise.

Correlated information, mechanism design and informational rents
Creators: name: Parreiras, Sérgio
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: The optimal mechanism literature shows that the principal can extract all the equilibrium payoffs at a given Bayesian Game when the players’ information is correlated. For this result to hold, the principal needs to know how informative are the agents’ signals. If the principal does not know how noisy the signal of a player is, or equivalently, when the signals available to a player can be ranked in order of informativeness by Blackwell’s criterion, any informational rents obtained at the game are left to the players. Conversely, whenever the optimal mechanism leaves a positive surplus to some player, it is always possible to interpret the model as if, the principal were uncertain regarding how noisy is the signal of that player. Finally, although signals may be highly correlated, Blackwell’s ranking implies that the degree of informativeness of a player’s signal ought to be independent on the degree of informativeness of others’ signals.

description: Although the inflationary paradigm is the most widely accepted explanation for the current cosmological observations, it does not necessarily correspond to what actually happened in the early stages of our Universe. To decide on this issue, two paths can be followed: first, all the possible predictions it makes must be derived thoroughly and compared with available data, and second, all imaginable alternatives must be ruled out. Leaving the first task to all other contributors of this volume, we concentrate here on the second option, focusing on the bouncing alternatives and their consequences.

description: An electron-phonon system at commensurate filling often displays charge order (CO) in the ground state. Such a system subject to a laser pulse shows a wide variety of behaviour. A weak pulse sets up low amplitude oscillations in the order parameter, with slow decay to a slightly suppressed value. A strong pulse leads to the destruction of the charge order with the order parameter showing rapid, oscillatory, decay to zero. The regime in between, separating the weak pulse CO sustained state from the strong pulse CO destroyed state, shows complex dynamics characterised by multiple, pulse strength dependent, time scales. It involves an initial rapid decay of the order parameter, followed by a low amplitude quiescent state, and the power-law rise to a steady-state over a timescale $τ_{cr}$. We provide a complete characterisation of the dynamics in this nonequilibrium problem for varying electron-phonon coupling and pulse strength, examine the possibility of an effective "thermal" description of the long time state, and present results on the multiple insulator-metal transitions that show up.

The dynamics of risk-sensitive allocations
Creators: name: Anderson, Evan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: This paper describes Pareto optimal allocations when agents have risk-sensitive preferences as formulated by Hansen and Sargent (1995). Necessary and sufficient conditions are given for the existence of a steady state at which Pareto weights are time-invariant. Sufficient conditions are given for steady states to be stable or unstable. When all agents are risk-sensitive with power reward functions there is a unique interior steady state. This steady state is stable when the power is positive and unstable when the power is negative. When there is at least one agent with time-additive preferences eventually all risk-sensitive agents have zero Pareto weights.

description: En su primera novela, El huésped (2006), Guadalupe Nettel se mueve en el territorio de lo fantástico hispanoamericano reelaborando las realidades paralelas de Borges, las duplicaciones y los seres invisibles de Cortázar y Dávila, los fantasmas de Rulfo y las conspiraciones y la oscuridad de Ocampo y Sabato. A través de la vida de Ana, una niña habitada por un monstruo interior que ocupa su espacio físico y visual, la autora explora las sombras del mundo de los invidentes. Al desdoblamiento del cuerpo tomado por la extraña y violenta presencia corresponde un desdoblamiento urbano: los subterráneos de la Ciudad de México revelan esa misma periferia existencial que Foucault localiza en la desobedencia de los a-normales a la normalización del poder dominante. El ojo de Nettel, que realmente padece la opacidad de la ceguera, abre la visión del lector a una multitud de refracciones que encuentran, en la estética de lo marginal, una nueva estética de lo humano.

description: Hazard mitigation planners claim that foresighted present actions and investments produce significant future benefits. However, they have difficulty in supporting their claims, since previously their evidence typically was derived from individual case studies. Constituents and decision makers are often skeptical, believing that individual cases are either inapplicable to their situation or non-randomly selected to support a particular view. Planners need objective evidence based on a large body of experience to support the case for mitigation. Such is the unique contribution of a recent congressionally-mandated study, Natural Hazard Mitigation Saves (MMC, 2005). Using an aggregate of project-level benefit-cost analyses (estimation of average benefit-cost efficiency based on a random sample from a large data set), the study found that each dollar spent in three federal natural hazard mitigation grant programs--the Hazard Mitigation Grant Program, Project Impact, and the Flood Mitigation Assistance Program- saves society an average of $4 in future avoided losses. Complementing the aggregate benefit-cost analysis with community-based evaluations, the study yielded valuable insights on how planners can improve long-term community resilience in the face of extreme events. To conduct the overall study, a number of methodological innovations were necessary, including developing a consistent methodology based on modifications and extensions of HAZUS-MH loss estimation software to cover wind damage, business interruption from lifelines, and population displacement. Valuable lessons for mitigation planners and policy makers emerged: the need to consider a wide variety of losses, the importance of mixing qualitative with quantitative analysis, the value of averaging results over a large number of projects, and the need to more explicitly address social issues and data collection in order to reduce vulnerability and enhance resilience to cope with twenty-first century hazards.

Explicit formula for the Holevo bound for two-parameter qubit estimation problem
Creators: name: Suzuki, Jun
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The main contribution of this paper is to derive an explicit expression for the fundamental precision bound, the Holevo bound, for estimating any two-parameter family of qubit mixed-states in terms of quantum versions of Fisher information. The obtained formula depends solely on the symmetric logarithmic derivative (SLD), the right logarithmic derivative (RLD) Fisher information, and a given weight matrix. This result immediately provides necessary and sufficient conditions for the following two important classes of quantum statistical models; the Holevo bound coincides with the SLD Cramer-Rao bound and it does with the RLD Cramer-Rao bound. One of the important results of this paper is that a general model other than these two special cases exhibits an unexpected property: The structure of the Holevo bound changes smoothly when the weight matrix varies. In particular, it always coincides with the RLD Cramer-Rao bound for a certain choice of the weight matrix. Several examples illustrate these findings.

Doubly-Iterative Sparsified MMSE Turbo Equalization for OTFS Modulation

description: Currently, orthogonal time frequency space (OTFS) modulation has drawn much attention to reliable communications in high-mobility scenarios. This paper proposes a doubly-iterative sparsified minimum mean square error (DI-S-MMSE) turbo equalizer, which iteratively exchanges the extrinsic information between a soft-input-soft-input (SISO) MMSE estimator and a SISO decoder. Our proposed equalizer does not suffer from short loops and approaches the performance of the near-optimal symbol-wise maximum a posteriori (MAP) algorithm. To exploit the inherent sparsity of OTFS system, we resort to graph theory to investigate the sparsity pattern of the channel matrix, and propose two sparsification guidelines to reduce the complexity of calculating the matrix inverse at the MMSE estimator. Then, we apply two iterative algorithms to MMSE estimation, i.e., the Generalized Minimal Residual (GMRES) and Factorized Sparse Approximate Inverse (FSPAI) algorithms. The former is used at the initial turbo iteration, whose global convergence is proven in our equalizer, while the latter is used at the subsequent turbo iterations with the help of our proposed guidelines. Simulation results demonstrate that our equalizer has a linear order of complexity while the performance loss incurred by the sparsification is only 0.2 dB at $10^{-4}$ bit error rate. Simulation codes are available to reproduce the results presented in this paper: https://github.com/Alga53/DISMMSE-Turbo-Equalizer-for-OTFS.

description: In a context where the research career patterns are dramatically changing, it is increasingly difficult for early career researchers to anticipate and prepare for their future careers. In this paper, we examine this issue by drawing on data from three recent studies conducted with European early career researchers using qualitative and quantitative methods. Our findings highlight that beyond the research and generic skills these researchers have acquired throughout their academic paths, some of them also developed a contemporary type of meta- competency defined as career competency. The latter refers to reflexive communicative and behavioural skills, knowledge and abilities that help one to cope with uncertain professional contexts. The relevance of this type of competency for career development interventions is discussed, and further research perspectives are provided.

description: To understand the contact patterns of a population -- who is in contact with whom, and when the contacts happen -- is crucial for modeling outbreaks of infectious disease. Traditional theoretical epidemiology assumes that any individual can meet any with equal probability. A more modern approach, network epidemiology, assumes people are connected into a static network over which the disease spreads. Newer yet, temporal network epidemiology, includes the time in the contact representations. In this paper, we investigate the effect of these successive inclusions of more information. Using empirical proximity data, we study both outbreak sizes from unknown sources, and from known states of ongoing outbreaks. In the first case, there are large differences going from a fully mixed simulation to a network, and from a network to a temporal network. In the second case, differences are smaller. We interpret these observations in terms of the temporal network structure of the data sets. For example, a fast overturn of nodes and links seem to make the temporal information more important.

description: We present measurements of airborne fission products in Chapel Hill, NC, USA, from 62 d following the March 11, 2011, accident at the Fukushima Dai-ichi nuclear power plant. Airborne particle samples were collected daily in air filters and radio-assayed with two high-purity germanium (HPGe) detectors. The fission products 131I and 137Cs were measured with maximum activity concentrations of 4.2 ± 0.6 mBq/m3 and 0.42 ± 0.07 mBq/m3 respectively. Additional activity from 131,132I, 134,136,137Cs and 132Te were measured in the same air filters using a low-background HPGe detector at the Kimballton Underground Research Facility (KURF).
Yukawa Unification in an SO(10) SUSY GUT: SUSY on the Edge

description: In this paper we analyze Yukawa unification in a three family SO(10) SUSY GUT. We perform a global $χ^2$ analysis and show that SUSY effects do not decouple even though the universal scalar mass parameter at the GUT scale, $m_{16}$, is found to lie between 15 and 30 TeV with the best fit given for $m_{16} \approx 25$ TeV. Note, SUSY effects don't decouple since stops and bottoms have mass of order 5 TeV, due to RG running from $M_{GUT}$. The model has many testable predictions. Gauginos are the lightest sparticles and the light Higgs boson is very much Standard Model-like. The model is consistent with flavor and CP observables with the $BR(μ\to eγ)$ close to the experimental upper bound. With such a large value of $m_{16}$ we clearly cannot be considered "natural" SUSY nor are we "Split" SUSY. We are thus in the region in between or "SUSY on the Edge."

Measuring and documenting graduate learning outcomes in the co-curricular space
Creators: name: Sim, Alvin
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: Co-curricular experiences provide valuable out-of-classroom learning experiences that are platforms for students to critically reflect upon and expand their perspectives. This is crucial in developing the future-ready graduate. Due to the unique nature of out-of-classroom learning, co-curricular experiences often provide learning opportunities that may be quite distinct from academic learning experiences. We contend that co-curricular experiences warrant a fair amount of attention, particularly for their ability to help students develop real-world employability skills (Peck, 2017). This paper seeks to uncover how Transformative Learning can applied in the co-curricular sphere, and its implications in designing, curating and implementing co-curricular activities. SMU’s approach to measuring and documenting students’ learning in the co-curricular space, including its unique co-curricular learning cycle, will also be shared.

Optimization of Vierendeel-type steel structure by means of nonlinear numerical analyses

Publisher: name: Zenodo
Year: 2022

description: The development of technology combined with the improvement and upgrade of the software algorithms used by engineers, provides the opportunity of investigating the behavior of a construction under any conditions with very good accuracy. In the present thesis, the object is to empirically investigate the margin for optimizing the plate thickness of the steel parts and the connections of a Vierendeel beam (upper chord, lower chord and vertical members). The results of this work can form the basis for the creation and application of optimization algorithms that will have the advantage of automation. Initially the model is designed with beam elements, in order to select the dimensions and thickness of the cross sections based on the deflection displacement of the structure. The cross sections are hollow square, and after checking the results at the level of stresses and deflection displacement, then a second model of the same structure with shell elements is drawn. In the shell-element model, cross sections are designed with corners and not with curved sections. This simplification implies greater concetration of tensions at connection points of vertical members with chords. However, this small difference does not significantly affect the conclusions in the end. For this purpose, initially the analyses carried out are linear and the areas-zones that are candidates for optimization are being selected. An overview of the strain and stress distribution on the structure is taken by the results of the linear analysis. Furthermore, some zones can be accordingly defined around the connections, which may be selected to optimize their thickness. Eventually, by performing non-linear analyses, some models get to emerge which have a different thickness in some zones compared to the original model. The results of the non-linear analyses lead to conclusions about the type of optimization that can be implemented. The optimization of cross-sections aims to lead to a model that behaves similar to the designed one, using as much less material as possible.

description: Many models of dark energy have been proposed to describe the universe since the beginning of the Big Bang. In this study, we present a new model of agegraphic dark energy ($NADE$) based on the three generalized uncertainty principles $KMM$ (Kempf, Mangan, Mann), Nouicer and $GUP^{*}$ ( higher orders generalized uncertainty principle).Using the obtained relations from three of types of $GUP$, in the form of three scenarios(Emergent,Intermediate,Logamediate), we consider three different eras of the universe evolution. Also we describe the evolution and expansion of the universe in each subsection. We will plot the obtained relations in these models for better comparatione.

Spectral Mackey functors and equivariant algebraic K-theory (II)

description: We study the "higher algebra" of spectral Mackey functors, which the first named author introduced in Part I of this paper. In particular, armed with our new theory of symmetric promonoidal $\infty$-categories and a suitable generalization of the second named author's Day convolution, we endow the $\infty$-category of Mackey functors with a well-behaved symmetric monoidal structure. This makes it possible to speak of spectral Green functors for any operad $O$. We also answer a question of A. Mathew, proving that the algebraic $K$-theory of group actions is lax symmetric monoidal. We also show that the algebraic $K$-theory of derived stacks provides an example. Finally, we give a very short, new proof of the equivariant Barratt-Priddy-Quillen theorem, which states that the algebraic $K$-theory of the category of finite $G$-sets is simply the $G$-equivariant sphere spectrum.

description: Wavelike, bosonic dark matter candidates like axions and dark photons can be detected using microwave cavities known as haloscopes. Traditionally, haloscopes consist of tunable copper cavities operating in the TM$_{010}$ mode, but ohmic losses have limited their performance. In contrast, superconducting radio frequency (SRF) cavities can achieve quality factors of $\sim 10^{10}$, perhaps five orders of magnitude better than copper cavities, leading to more sensitive dark matter detectors. In this paper, we first derive that the scan rate of a haloscope experiment is proportional to the loaded quality factor $Q_L$, even if the cavity bandwidth is much narrower than the dark matter halo line shape. We then present a proof-of-concept search for dark photon dark matter using a nontunable ultrahigh quality SRF cavity. We exclude dark photon dark matter with kinetic mixing strengths of $χ> 1.5\times 10^{-16}$ for a dark photon mass of $m_{A^{\prime}} = 5.35μ$eV, achieving the deepest exclusion to wavelike dark photons by almost an order of magnitude.

description: Recent observation of Sagittarius A$^*$ (Sgr A$^*$) by the Event Horizon Telescope (EHT) collaboration has uncovered various unanswered questions in black hole (BH) physics. Besides, it may also probe various beyond the Standard Model (BSM) scenarios. One of the most profound possibilities is the search for ultralight bosons (ULBs) using BH superradiance (SR). EHT observations imply that Sgr A$^*$ has a non-zero spin. Using this observation, we derive bounds on the mass of ULBs with purely gravitational interactions. Considering self-interacting ultralight axions, we constrain new regions in the parameter space of decay constant, for a certain spin of Sgr A$^*$. Future observations of various spinning BHs can improve the present constraints on ULBs.

Engaging faculty in designing inclusive and collaborative classroom strategies with students with disabilities: A guide for faculty developers
Creators: name: Schley, Sara
name: Marchetti, Carol
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: Classroom disabilities are part of the diversity landscape. Usually, faculty address the needs of students with disabilities in their classrooms by honoring accommodations requests – letters from a disability services office detailing a students’ needs (e.g., presence of ASL/English interpreter in the classroom, extended time on a test, large-print handouts, digital versions of slides, etc.). From there, faculty allow for the accommodation(s), and the course continues as planned – with minimal adaptation on the part of a faculty member or class participants (Schley, 2018). There are small pedagogical changes that faculty can make to increase the inclusion of students with disabilities, and improve interaction between all enrolled students (Cawthon, Jassal & Schley, in press; Cawthon, Schley & Davidson, 2019; Marchetti et al. 2019; Marchetti, Foster, Long & Stinson, 2012). Often, these strategies can also make the job of teaching more efficient and effective.
