description: A consistent explanation of the formation of a ring-shaped pattern of exciton luminescence in GaAs/AlGaAs double quantum wells is suggested. The pattern consists of two concentric rings around the laser excitation spot. It is shown that the luminescence rings appear due to the in-layer transport of hot charge carriers at high photoexcitation intensity. Interestingly, one of two causes of this transport might involve self-organized criticality (SOC) that would be the first case of the SOC observation in semiconductor physics. We test this cause in a many-body numerical model by performing extensive molecular dynamics simulations. The results show good agreement with experiments. Moreover, the simulations have enabled us to identify the particular kinetic processes underlying the formation of each of these two luminescence rings.

description: Microtubule affinity regulating kinase (MARK4) has been proposed as a potential therapeutic target for diabetes, cancer, and neurological diseases. We used a variety of computational studies techniques to examine the binding affinity and MARK4 inhibitory potential of several isoquinoline alkaloids. MARK4 has been associated with tau protein phosphorylation and, consequently, Alzheimer’s disease. The three molecules with the highest binding affinities inside the 5ES1 receptor, according to molecular docking experiments, are isoliensinine, liensinine, and methylcorypalline. Isoliensinine had the highest drug score and drug likeness, coming in at 1.17, while Liensinine and Methylcorypalline came in at 1.15 and 1.07, respectively. The thesis claims that three compounds have a better chance than the others of being identified as therapeutic leads. The bulk of the compounds under investigation didn’t break any of Lipinski’s five rules, especially methylcorypalline, which did and is probably orally active. The majority of the compounds under investigation, particularly Isoliensinine, Liensinine, and Methylcorypalline, show the potential to exhibit drug-like behaviour, which is strongly confirmed by ADMET characteristics estimates. The chemicals Isoliensinine, Liensinine, and Methylcorypalline, especially Methylcorypalline, form the most stable combination with the 5ES1, according to a 100 ns molecular dynamics simulation of these compounds docked inside 5ES1 complexes. Methylcorypalline has a higher binding affinity inside 5ES1, according to additional MM/GBSA experiments using MD trajectories. Overall, research supports the use of the drug development tool methylcolipalin for its ability to inhibit MARK4, which may have implications for the treatment of neurodegenerative diseases.

description: A Software-defined Constrained Optimal Routing (SCOR) platform is introduced as a Northbound interface in SDN architecture. It is based on constraint programming techniques and is implemented in MiniZinc modelling language. Using constraint programming techniques in this Northbound interface has created an efficient tool for implementing complex Quality of Service routing applications in a few lines of code. The code includes only the problem statement and the solution is found by a general solver program. A routing framework is introduced based on SDN's architecture model which uses SCOR as its Northbound interface and an upper layer of applications implemented in SCOR. Performance of a few implemented routing applications are evaluated in different network topologies, network sizes and various number of concurrent flows.

description: Let $Ω$ be the set of odd positive integers and let $S:Ω\rightarrow Ω$ be the Syracuse function. It is proved that, for every permutation $σ$ of $(1,2,3)$, the set of triples of the form $(m,S(m),S^2(m))$ with permutation pattern $σ$ has positive density, and these densities are computed. However, there exist permutations $τ$ of $(1,2,3,4)$ such that no quadruple $(m,S(m), S^2(m), S^3(m))$ has permutation pattern $τ$. This implies the nonexistence of certain permutation patterns of $n$-tuples $(m,S(m),\ldots, S^{n-1}(m))$ for all $n \geq 4$.

description: We study the Polycyclic Aromatic Hydrocarbons (PAH) bands, ionic emission lines, and Mid-infrared continuum properties, in a sample of 171 emission line galaxies taken from literature plus 15 new active galactic nuclei (AGN) Spitzer spectra. The continuum shape steeply rises for longer wavelengths and can be fitted with a warm blackbody distribution of T=150-300K. The brightest PAH spectral bands (6.2, 7.7, 8.6, 11.3, and 12.7$μ$m) and the forbidden emission lines of [Si II] 34.8$μ$m, [Ar II] 6.9, [S III] 18.7 and 33.4 were detected in all the Starbursts and in ~80% of the Seyfert~2. Taking under consideration only the PAH bands at 7.7$μ$m, 11.3$μ$m, and 12.7$μ$m we find they are present in ~80% of the Seyfert 1, while only half of this type of activity show the 6.2$μ$m and 8.6 PAH bands. The observed intensities ratios for neutral and ionized PAHs (6.2/7.7 x 11.3/7.7) were compared to theoretical intensity ratios, showing that AGNs have higher ionization fraction and larger PAH (> 180 carbon atoms) than SB galaxies. The ratio between the ionized (7.7) and the neutral PAH bands (8.6 and 11.3) are distributed over different ranges for AGNs and SB galaxies, suggesting that these ratios could depend on the ionization fraction, as well as on the hardness of the radiation field. The ratio between the 7.7 and 11.3 bands is nearly constant with the increase of [Ne III]15.5/[Ne II], indicating that the fraction of ionized to neutral PAH bands does not depend on the hardness of the radiation field. The equivalent width of both PAH features show the same dependence with [Ne III]/[Ne II], suggesting that the PAH, emitting either ionized (7.7) or neutral (11.3) bands, may be destroyed with the increase of the hardness of the radiation field.

The paper The Far Future of Exoplanet Direct Characterization resulted from the collective work of TE-SAT, a team appointed by ESA in 2003 to assess a strategy to find and characterize Terrestrial Exoplanets. The interstellar flight aspect was not part of the TE-SAT work and was added afterward as side remarks in the chapter on « The Far Future of Exoplanet Direct Characterization ». As an introductory general remark, the intention of the paper was not to discourage work on interstellar flight prospective. On the contrary, any advance in this field that makes interstellar travel closer to us is welcome. In the framework of this short reply, the discussion can only be qualitative; it would deserve a full future paper.

description: Higgs inflation uses the gauge variant Higgs field as the inflaton. During inflation the Higgs field is displaced from its minimum, which results in associated Goldstone bosons that are apparently massive. Working in a minimally coupled U(1) toy model, we use the closed-time-path formalism to show that these Goldstone bosons do contribute to the one-loop effective action. Therefore the computation in unitary gauge gives incorrect results. Our expression for the effective action is gauge invariant upon using the background equations of motion.

description: A strategic plan can act as a guide for determing priorities and supporting effective implementation of a library's overall goals. With the day-to-day work of librarianship, however, it can become difficult to be reflective practitioners and craft a meaningful strategic plan. Once written, the challenge also becomes maintaining it as a living document that all library staff embody and not something that simply gets filed away without being fully implemented. In fall 2018, the Priddy Library at The Universities at Shady Grove began the process of creating its first strategic plan. This presentation will share the approaches and experiences of Priddy Library staff in this endeavor. It will demonstrate how the planning process not only provides a means to incorporate systematic assessment and financial needs of the library, but also serves as a way to strengthen partnerships, develop staff skills and increase awareness about the value of the library.

description: We extend the variational cluster approach to deal with strongly correlated lattice bosons in the superfluid phase. To this end, we reformulate the approach within a pseudoparticle formalism, whereby cluster excitations are described by particlelike excitations. The approximation amounts to solving a multicomponent noninteracting bosonic system by means of a multimode Bogoliubov approximation. A source-and-drain term is introduced in order to break U(1) symmetry at the cluster level. We provide an expression for the grand potential, the single-particle normal and anomalous Green's functions, the condensate density, and other static quantities. As a first nontrivial application of the method we choose the two-dimensional Bose-Hubbard model and evaluate results in both the Mott and the superfluid phases. Our results show an excellent agreement with quantum Monte Carlo calculations.

“Craft beer is good not only if it does good, but if it is good” : how key decision makers in craft breweries across British Columbia (BC) understand doing good
Creators: name: Moore, Harriet Christine
Publisher: name: University of British Columbia
Year: 2022

description: Extensive research has been conducted by food and tourism theorists on the rise of meaningful consumption, conscious consumers, and ability for products to hold cultural value. Today, there is limited research on how key decision makers in small businesses understand and demonstrate conscious and meaningful production (Barman, 2016). Specifically, how key decision makers, in the craft brewing context understand and demonstrate their morals and values. Craft breweries in British Columbia (BC) are a worthy site for this research, as this industry has experienced outstanding growth and expansion across the province. In this research, I ask how key decision makers in craft breweries across BC construct, defend, and maintain ideas of doing 'good'. My research proposes that respondents use a wide range of strategies to discuss and do good business. In 2021, I conducted and analyzed 31 in-depth, one-on-one, semi-structured interviews with industry participants (Said, 2019) using video-conferencing technologies. Results show that my respondents understand doing good in three main ways. First, respondents share an attitude of comradery and a 'rising-tide lifts all boats’ mentality to fight against obstacles like ‘big-beer’ and the Covid-19 pandemic. Second, respondents believe good craft beer is authentic craft beer. To some, authenticity is understood through facets like process and choice of ingredients. Third, respondents use their tasting rooms as third places (Oldenburg, 1999) to foster community. My results confirm that key decision makers draw from a strong cultural repertoire (Cohen & Dromi, 2018) to communicate moral values and generate positive social action (Swidler, 1986). Respondents participate in various value creation activities (Xie et al., 2008), such as making ‘benefit brews.’ Through these, key decision makers can choose to donate proceeds to a notable cause or support their local arts communities by hosting exhibits in their tasting rooms and printing artists’ work on their beer cans. These results are significant for understanding the scope of meaningful production and how craft breweries across BC can create positive effects on their local communities in economic and social ways. Future research might include conducting semi-structured interviews with key decision makers in macrobreweries to understand how they interpret similar themes.

description: We explore the microwave anisotropies at large angular scales produced by the emission from cold and large dust grains, expected to exist in the outer parts of the Solar System, using a simple toy model for this diuse emission. Its amplitude is constrained in the Far-IR by the COBE data and is compatible with simulations found in the literature. We analyze the templates derived after subtracting our model from the WMAP ILC 7 yr maps and investigate on the cosmological implications of such a possible foreground. The anomalies related to the low quadrupole of the angular power spectrum, the two-point correlation function, the parity and the excess of signal found in the ecliptic plane are significantly alleviated. An impact of this foreground for some cosmological parameters characterizing the spectrum of primordial density perturbations, relevant for on-going and future CMB anisotropy experiments, is found.

description: Continuous gauge theories, because of their bosonic degrees of freedom, have an infinite-dimensional local Hilbert space. Encoding these degrees of freedom on qubit-based hardware demands some sort of ``qubitization'' scheme, where one approximates the behavior of a theory while using only finitely many degrees of freedom. We propose a novel qubitization strategy for gauge theories, called ``fuzzy gauge theory,'' building on the success of the fuzzy $σ$-model in earlier work. We provide arguments that the fuzzy gauge theory lies in the same universality class as regular gauge theory, in which case its use would obviate the need of any further limit besides the usual spatial continuum limit. Furthermore, we demonstrate that these models are relatively resource-efficient for quantum simulations.

Continuous Average Straightness in Spatial Graphs
Creators: name: Labatut, Vincent
Publisher: name: arXiv
Year: 2017
Subjects: subject: Discrete Mathematics (cs.DM)
subject: FOS: Computer and information sciences

description: The Straightness is a measure designed to characterize a pair of vertices in a spatial graph. It is defined as the ratio of the Euclidean distance to the graph distance between these vertices. It is often used as an average, for instance to describe the accessibility of a single vertex relatively to all the other vertices in the graph, or even to summarize the graph as a whole. In some cases, one needs to process the Straightness between not only vertices, but also any other points constituting the graph of interest. Suppose for instance that our graph represents a road network and we do not want to limit ourselves to crossroad-to-crossroad itineraries, but allow any street number to be a starting point or destination. In this situation, the standard approach consists in: 1) discretizing the graph edges, 2) processing the vertex-to-vertex Straightness considering the additional vertices resulting from this discretization, and 3) performing the appropriate average on the obtained values. However, this discrete approximation can be computationally expensive on large graphs, and its precision has not been clearly assessed. In this article, we adopt a continuous approach to average the Straightness over the edges of spatial graphs. This allows us to derive 5 distinct measures able to characterize precisely the accessibility of the whole graph, as well as individual vertices and edges. Our method is generic and could be applied to other measures designed for spatial graphs. We perform an experimental evaluation of our continuous average Straightness measures, and show how they behave differently from the traditional vertex-to-vertex ones. Moreover, we also study their discrete approximations, and show that our approach is globally less demanding in terms of both processing time and memory usage.

description: We consider a broad class of supersymmetric theories in which dark matter (DM) is the lightest superpartner (LSP) of a hidden sector that couples very weakly to visible sector fields. Portal interactions connecting visible and hidden sectors mediate the decay of the lightest observable superpartner (LOSP) into the LSP, allowing the LHC to function as a spectacular probe of the origin of hidden sector DM. As shown in a companion paper, this general two-sector framework allows only for a handful of DM production mechanisms, each of which maps to a distinctive window in lifetimes and cross-sections for the LOSP. In the present work we perform a systematic collider study of LOSP candidates and portal interactions, and for each case evaluate the prospects for successfully reconstructing the origin of DM at the LHC. If, for instance, DM arises from Freeze-Out and Decay, this may be verified if the LOSP is a bino or right-handed slepton decaying to the LSP through a variety of portal interactions, and with an annihilation cross-section within a narrow range. On the other hand, the Freeze-In mechanism may be verified for a complimentary set of LOSP candidates, and within a narrow range of LOSP lifetimes. In all cases, the LOSP is relatively long-lived on collider time scales, leading to events with displaced vertices. Furthermore, scenarios with a charged or colored LOSP are particularly promising.

description: We explore the physical origin and robustness of constraints on the energy density in relativistic species prior to and during recombination, often expressed as constraints on an effective number of neutrino species, Neff. Constraints from current data combination of Wilkinson Microwave Anisotropy Probe (WMAP) and South Pole Telescope (SPT) are almost entirely due to the impact of the neutrinos on the expansion rate, and how those changes to the expansion rate alter the ratio of the photon diffusion scale to the sound horizon scale at recombination. We demonstrate that very little of the constraining power comes from the early Integrated Sachs-Wolfe (ISW) effect, and also provide a first determination of the amplitude of the early ISW effect. Varying the fraction of baryonic mass in Helium, Yp, also changes the ratio of damping to sound-horizon scales. We discuss the physical effects that prevent the resulting near-degeneracy between Neff and Yp from being a complete one. Examining light element abundance measurements, we see no significant evidence for evolution of Neff and the baryon-to-photon ratio from the epoch of big bang nucleosynthesis to decoupling. Finally, we consider measurements of the distance-redshift relation at low to intermediate redshifts and their implications for the value of Neff.

In this paper we investigate the observational viability of some accelerating cosmological models in light of 32 age measurements of passively evolving galaxies as a function of redshift and recent estimates of the product of the cosmic microwave background acoustic scale and the baryonic acoustic oscillation peak scale. By using information-criteria model selection, we select the best-fit models and rank the alternative scenarios. We show that some of these models may provide a better fit to the data than does the current standard cosmological constant dominated ($Λ$CDM) model.

description: Fahrzeugbewegungen im Bahnverkehr erfordern aufgrund von Spurbindung und langen Bremswegen ein hohes Maß an Regulierung und technischer Absicherung, um Kollisionen zu vermeiden. Signale sind ein wesentlicher Teil dieser Leit- und Sicherungstechnik, die sämtliche Zugfahrten steuert. Sie müssen in kognitiv beanspruchenden Prozessen der Daueraufmerksamkeit von den Triebfahrzeugführern überwacht werden, die aus ihnen Anweisungen zur Geschwindigkeitsregulation ableiten und umsetzen. Vorbeifahrten von Zügen an Signalen mit Haltbegriff zählen jedoch zu den häufigsten Gefährdungen im Bahnbetrieb. In vielen europäischen Ländern werden daher Zugsicherungssysteme auf Basis punktförmiger Beeinflussung eingesetzt, um die Risiken „zufälliger menschlicher Fehler“ bei der Signalbeachtung zu verringern. Die Gesamtzahl der kritischen Ereignisse bleibt dennoch hoch, da die Systeme erst eingreifen, wenn der Fehler im Bremsprozess bereits eingetreten ist. Zieht man in Betracht, dass Signalverstöße in Fehlerklassifikationen überwiegend auf „ungünstige mentale Zustände“ der Lokführer zurückgeführt werden, sollten die Einflussfaktoren auf deren Entstehung vor diesem Hintergrund systematisch untersucht werden. Aktuell gibt es aber keine empirischen Befunde zu den Auswirkungen, die solche Systeme, beispielsweise die deutsche „PZB 90“, auf die Bedienerzustände und Performanz von Triebfahrzeugführern bei Ausübung ihrer Fahr- und Kontrollaufgaben haben. Ein entsprechendes kognitives Wirkungsmodell für den Zusammenhang zwischen Aufmerksamkeitsdefiziten und Vorbeifahrten am Haltsignal wurde auf Basis der Arbeiten von Endsley sowie Parasuraman und Manzey entwickelt. Dies wird im vorliegenden Artikel ausführlich dargestellt. In einem weiteren Schritt wird beschrieben, wie dieses Modell in der Simulationsumgebung RailSET® experimentell überprüft werden soll. Dabei wird angenommen, dass es unter Nutzung des Zugsicherungssystems zu Zuständen der verminderten Vigilanz und Passivität der Triebfahrzeugführer kommt, welche auch monotone Bedienerzustände kennzeichnen. Es wird erwartet, dass die Bedienerzustände durch spezifische Verhaltensweisen gekennzeichnet sind. Blickbewegungsmessung soll zum Einsatz kommen, um Verschiebungen in der Aufmerksamkeitsverteilung zu analysieren. Auch Reaktionszeitmaße und ein Nebenaufgabenparadigma sollen Anwendung finden. Im Ausblick werden abschließend Ansätze diskutiert, wie Aufmerksamkeitsdefiziten gezielt entgegenwirkt werden und damit ein echter Assistenz-Charakter der Zugsicherung erreicht werden kann.

description: The precise measurement of the W boson mass is closely related to the contributions of new physics (NP), which can significantly constrain the parameter space of NP models, particularly those with an additional $U(1)$ local gauge group. The inclusion of a new $Z'$ gauge boson and gauge couplings in these models can contribute to the oblique parameters $S$, $T$, $U$ and W boson mass at tree level. Taking into account the effects of kinetic mixing, we calculate and analyze the oblique parameters $S$, $T$, $U$ and W boson mass in such NP models in this study. It is found that the kinetic mixing effects can make significant contributions to the W boson mass, which can satisfy the recently measured W boson mass at CDF II or ATLAS by choosing appropriate values of gauge coupling constants and extra $U(1)$ group charges of leptons or scalar doublets. In addition, if the leptonic Yukawa couplings are invariant under the extra $U(1)$ local gauge group, these contributions can be eliminated by redefining the gauge boson fields through eliminating the neutral currents involving charged leptons, even with nonzero kinetic mixing effects.

description: Optical imaging through diffusive, visually-opaque barriers, and around corners is an important challenge in many fields, ranging from defense to medical applications. Recently, novel techniques that combine time-of-flight (TOF) measurements with computational reconstruction, have allowed breakthrough imaging and tracking of objects hidden from view. These light detection and ranging (LiDAR)-based approaches, however, require active short-pulsed illumination and ultrafast time-resolved detection. Here, bringing notions from passive RADAR and passive geophysical mapping approaches, we present an optical TOF technique that allows to passively localize light sources and reflective objects through diffusive barriers and around corners. Our approach retrieves TOF information from temporal cross-correlations of scattered light, providing temporal resolution that surpasses the state-of-the-art ultrafast detectors by three orders of magnitude. We demonstrate passive localization of multiple white-light sources and reflective objects hidden from view, using a simple setup, with interesting potential for covert imaging.

description: Although young people spend increasing amounts of time on the internet, many caveats remain in the literature with regard to the development of digital skills. We focus on the influence of perceived discrimination given its strong link with youth development. We also consider the multidimensional nature of digital skills, focusing on five dimensions, and on digital knowledge. Using online survey data from 6221 children and young people aged 12–20 in six European countries, we seek to understand how discriminated youths may differ from their more advantaged peers with respect to digital skills. The findings show that young people who are discriminated against generally hold greater digital skills than their counterparts who are not being discriminated against. The relationship between perceived discrimination and digital skills is partially mediated by peer support and internet use. We discuss these findings in light of young people’s increased social isolation due to discrimination.
The distribution of cycles in breakpoint graphs of signed permutations

description: Breakpoint graphs are ubiquitous structures in the field of genome rearrangements. Their cycle decomposition has proved useful in computing and bounding many measures of (dis)similarity between genomes, and studying the distribution of those cycles is therefore critical to gaining insight on the distributions of the genomic distances that rely on it. We extend here the work initiated by Doignon and Labarre, who enumerated unsigned permutations whose breakpoint graph contains $k$ cycles, to signed permutations, and prove explicit formulas for computing the expected value and the variance of the corresponding distributions, both in the unsigned case and in the signed case. We also compare these distributions to those of several well-studied distances, emphasising the cases where approximations obtained in this way stand out. Finally, we show how our results can be used to derive simpler proofs of other previously known results.

description: In this article we introduce conformal Riemannian morphisms. The idea of conformal Riemannian morphism generalizes the notions of an isometric immersion, a Riemannian submersion, an isometry, a Riemannian map and a conformal Riemannian map. We show that every injective conformal Riemannian morphism is an injective conformal immersion, and that on a connected manifold, every surjective conformal Riemannian morphism is a surjective conformal submersion, and every bijective conformal Riemannian morphism is a conformal map.

description: Mysterious craters, with anomalously high concentrations of methane, have formed in the Yamal and Taymyr peninsulas of Siberia since 2014. While thawing permafrost owing to climate warming promotes methane releases, it is unknown how such release might be associated with explosion and crater formation. A significant volume of surface ice-melt water can migrate downward driven by osmotic pressure associated with a cryopeg, a lens of salty water below. Overpressure reached at depth may lead to the cracking of the soil and subsequent decomposition of methane hydrates, with implications for the climate.
