description: We derive the field equations and the equations of motion for massive test particles in modified theories of gravity with an arbitrary coupling between geometry and matter by using the Palatini formalism. We show that the independent connection can be expressed as the Levi-Civita connection of an auxiliary, matter Lagrangian dependent metric, which is related with the physical metric by means of a conformal transformation. Similarly to the metric case, the field equations impose the non-conservation of the energy-momentum tensor. We derive the explicit form of the equations of motion for massive test particles in the case of a perfect fluid, and the expression of the extra-force is obtained in terms of the matter-geometry coupling functions and of their derivatives. Generally, the motion is non-geodesic, and the extra force is orthogonal to the four-velocity.

Energy loss of ions by electric-field fluctuations in a magnetized plasma

description: The results of a theoretical investigation of the energy loss of charged particles in a magnetized classical plasma due to the electric field fluctuations are reported. The energy loss for a test particle is calculated through the linear-response theory. At vanishing magnetic field the electric field fluctuations lead to an energy gain of the charged particle for all velocities. It has been shown that in the presence of strong magnetic field this effect occurs only at low-velocities. In the opposite case of high-velocities the test particle systematically loses its energy due to the interaction with a stochastic electric field. The net effect of the fluctuations is the systematic reduction of the total energy loss (i.e. the sum of the polarization and stochastic energy losses) at vanishing magnetic field and reduction or enhancement at strong field depending on the velocity of the particle. It is found that the energy loss of the slow heavy ion contains an anomalous term which depends logarithmically on the projectile mass. The physical origin of this anomalous term is the coupling between the cyclotron motion of the plasma electrons and the long-wavelength, low-frequency fluctuations produced by the projectile ion. This effect may strongly enhance the stochastic energy gain of the particle.

description: Multivariate dependence measures are crucial for risk management, where variables usually have heavy tails and non-Gaussian distributions. We propose a multivariate time varying Kendall’s tau estimator in a nonparametric context, allowing for local stationary variables. Consistency and asymptotic normality of the estimator are provided. A simulation study is conducted which supports the idea of better performance than other related methods in many complex scenarios. The proposal is used to draw up a daily estimation of the dependence between European financial market indexes. Nonparametric conditional quantiles are estimated to detect any influence of the degree of dependence on the market returns. That dependence emerges as an important factor in the Euro Stoxx distribution. It is noteworthy that the Kendall’s tau only depends on the multivariate copula, so the effect is not due to hidden effects of the marginals. Local Granger causality is tested and evidence is found that the degree of dependence affects the Euro Stoxx returns in the left tail of the distribution. We believe that these results encourage further research into the effect of diversification in quantiles, linked to the factors behind systemic risk. Additionally, there is a noteworthy increase in dependence following the outbreak of COVID-19.

description: Atmospheric pollution is one consequence of global-scale technology on Earth. Some technology elevates existing levels of atmospheric constituents in the atmosphere, while other industrial processes can contribute novel pollutants that would not otherwise be present. The detection of such pollutants in the atmosphere of an exoplanet would be compelling evidence for the existence of extraterrestrial technology. This poster highlights examples of the search for spectroscopic "technosignatures" in exoplanetary systems, such as elevated levels of chlorofluorocarbons and other pollutants. The era of JWST represents a pivotal transition in the ability for humanity to detect passive atmospheric technosignatures equal in strength to its own around the nearest stars.

description: Organic Zener diodes with a precisely adjustable reverse breakdown from -3 V to -15 V without any influence on the forward current-voltage curve are realized. This is accomplished by controlling the width of the charge depletion zone in a pin-diode with an accuracy of one nanometer independently of the doping concentration and the thickness of the intrinsic layer. The breakdown effect with its exponential current voltage behavior and a weak temperature dependence is explained by a tunneling mechanism across the HOMO-LUMO gap of neigh- boring molecules. The experimental data are confirmed by a minimal Hamiltonian model approach, including coherent tunneling and incoherent hopping processes as possible charge transport pathways through the effective device region.

description: Il volume presenta un lavoro di ricerca che ricostruisce il flusso migratorio dei minori stranieri non accompagnati (MSNA) arrivati in Italia negli ultimi decenni. Al centro dell’attenzione vi sono la storia dei viaggi, le motivazioni alla base della scelta migratoria, i contesti attraversati. Ad una lettura del fenomeno migratorio attraverso questi aspetti, però, si aggiunge un’analisi del sistema di accoglienza dedicato ai MSNA. La pluralità delle istituzioni deputate alla gestione migratoria si rivelano infatti un laboratorio di analisi privilegiato, in cui istanze securitarie e umanitarie si saldano, dove controllo e accoglienza divengono prassi che convivono in modo problematico negli stessi luoghi.

description: Little is known about the origin and basic properties of magnetic fields in clusters of galaxies. High conductivity in magnetized interstellar plasma suggests that galactic magnetic fields are (at least partly) ejected into intracluster (IC) space by the same processes that enrich IC gas with metals. We explore the dispersal of galactic fields by hydrodynamical simulations with our new {\em Enzo-Galcon} code, which is capable of tracking a large number galaxies during cluster assembly, and modeling the processes that disperse their interstellar media. Doing so we are able to describe the evolution of the mean strength of the field and its profile across the cluster. With the known density profile of dispersed gas and an estimated range of coherence scales, we predict the spatial distribution of Faraday rotation measure and find it to be consistent with observational data.

The role of self-coherence in correlations of bosons and fermions in linear counting experiments. Notes on the wave-particle duality
Creators: name: Varro, Sandor
Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Physics (quant-ph)

description: Correlations of detection events in two detectors are studied in case of linear excitation of the measuring apparatus. On the basis of classical probability theory and fundamental conservation laws, a general formula is derived for the two-point correlation functions for both bosons and fermions. The results obtained coincide with that derivable from quantum theory which uses quantized field amplitudes. By applying both the particle and the wave picture at the same time, the phenomena of photon bunching and antibunching, photon anticorrelation and fermion antibunching, measured in beam experiments, are interpreted in the frame of an intuitively clear description.

description: Invasive paper wasps such as Polistes dominula are a major pest and problem for biodiversity around the globe. Safe and highly targeted methods for the control of these and other social wasp populations are needed. We attempted to identify potentially-lethal gene targets that could be used on adult paper wasps in a gene silencing or RNA interference (RNAi) approach. Double-stranded RNA (dsRNA) was designed to target genes for which silencing has proven lethal in other insects. dsRNA was provided either orally to foragers or directly injected into the wasps. We also provided the dsRNA unprotected or protected from degradation by gut nucleases in two different forms (lipofectamine and carbon quantum dots). The effects of oral delivery of 22 different gene targets to forager wasps was evaluated. The expression of five different genes was successfully reduced following dsRNA ingestion or injection. These gene targets included the FACT complex subunit spt16 (DRE4) and RNA-binding protein fusilli (FUSILLI), both of which have been previously shown to have potential as lethal targets for pest control in other insects. However, we found no evidence of significant increases in adult wasp mortality following ingestion or injection of dsRNA for these genes when compared with control treatments in our experiments. The methods we used to protect the dsRNA from digestive degradation altered gene expression but similarly did not influence wasp mortality. Our results indicate that while many of the same gene targets can be silenced and induce mortality in other insects, dsRNA and RNAi approaches may not be useful for paper wasp control.

description: Consider a system governed by the time-dependent Schrödinger equation in its ground state. When subjected to weak (size $ε$) parametric forcing by an "ionizing field" (time-varying), the state decays with advancing time due to coupling of the bound state to radiation modes. The decay-rate of this metastable state is governed by {\it Fermi's Golden Rule}, $Γ[V]$, which depends on the potential $V$ and the details of the forcing. We pose the potential design problem: find $V_{opt}$ which minimizes $Γ[V]$ (maximizes the lifetime of the state) over an admissible class of potentials with fixed spatial support. We formulate this problem as a constrained optimization problem and prove that an admissible optimal solution exists. Then, using quasi-Newton methods, we compute locally optimal potentials. These have the structure of a truncated periodic potential with a localized defect. In contrast to optimal structures for other spectral optimization problems, our optimizing potentials appear to be interior points of the constraint set and to be smooth. The multi-scale structures that emerge incorporate the physical mechanisms of energy confinement via material contrast and interference effects. An analysis of locally optimal potentials reveals local optimality is attained via two mechanisms: (i) decreasing the density of states near a resonant frequency in the continuum and (ii) tuning the oscillations of extended states to make $Γ[V]$, an oscillatory integral, small. Our approach achieves lifetimes, $\sim (ε^2Γ[V])^{-1}$, for locally optimal potentials with $Γ^{-1}\sim\mathcal{O}(10^{9})$ as compared with $Γ^{-1}\sim \mathcal{O}(10^{2})$ for a typical potential. Finally, we explore the performance of optimal potentials via simulations of the time-evolution.

description: Spatially resolved tunneling spectroscopic studies of colossal magnetoresistive (CMR) manganite $\rm La_{0.7}Ca_{0.3}MnO_3$ (LCMO) epitaxial films on $\rm (LaAlO_3)_{0.3}(Sr_2AlTaO_6)_{0.7}$ substrate are investigated as functions of temperature, magnetic field and spin polarization by means of scanning tunneling spectroscopy. Systematic surveys of the tunneling spectra taken with Pt/Ir tips reveal spatial variations on the length scale of a few hundred nanometers in the ferromagnetic state, which may be attributed to the intrinsic heterogeneity of the manganites due to their tendency towards phase separation. The electronic heterogeneity is found to decrease either with increasing field at low temperatures or at temperatures above all magnetic ordering temperatures. On the other hand, spectra taken with Cr-coated tips are consistent with convoluted electronic properties of both LCMO and Cr. In particular, for temperatures below the magnetic ordering temperatures of both Cr and LCMO, the magnetic-field dependent tunneling spectra may be quantitatively explained by the scenario of spin-polarized tunneling in a spin-valve configuration. Moreover, a low-energy insulating energy gap $\sim 0.6$ eV commonly found in the tunneling conductance spectra of bulk metallic LCMO at $T \to 0$ may be attributed to a surface ferromagnetic insulating (FI) phase, as evidenced by its spin filtering effect at low temperatures and vanishing gap value above the Curie temperature. Additionally, temperature independent pseudogap (PG) phenomena existing primarily along the boundaries of magnetic domains are observed in the zero-field tunneling spectra. The PG becomes strongly suppressed by applied magnetic fields at low temperatures when the tunneling spectra of LCMO become highly homogeneous. These findings suggest that the occurrence PG is associated with the electronic heterogeneity of the manganites.

Redshift propagation equations in the $β' \neq 0$ Szekeres models

description: The set of differential equations obeyed by the redshift in the general $β' \neq 0$ Szekeres spacetimes is derived. Transversal components of the ray's momentum have to be taken into account, which leads to a set of 3 coupled differential equations. It is shown that in a general Szekeres model, and in a general Lema\^ıtre -- Tolman (L--T) model, generic light rays do not have repeatable paths (RLPs): two rays sent from the same source at different times to the same observer pass through different sequences of intermediate matter particles. The only spacetimes in the Szekeres class in which {\em all} rays are RLPs are the Friedmann models. Among the proper Szekeres models, RLPs exist only in the axially symmetric subcases, and in each one the RLPs are the null geodesics that intersect each $t =$ constant space on the symmetry axis. In the special models with a 3-dimensional symmetry group (L--T among them), the only RLPs are radial geodesics. This shows that RLPs are very special and in the real Universe should not exist. We present several numerical examples which suggest that the rate of change of positions of objects in the sky, for the studied configuration, is $10^{-6} - 10^{-7}$ arc sec per year. With the current accuracy of direction measurement, this drift would become observable after approx. 10 years of monitoring. More precise future observations will be able, in principle, to detect this effect, but there are basic problems with determining the reference direction that does not change.

Impact of urban densification on buried water infrastructure : assessing optimal growth scenarios
Creators: name: Kaur, Manjot
Publisher: name: University of British Columbia

description: Globally, rapid population growth and urbanization have been observed over the past few decades. This rapid growth raises urban development expectations; therefore, urban densification has become a promising approach for sustainable development. Urban densification can help achieve several sustainability goals by reducing land use, energy consumption, greenhouse gas (GHG) emissions, and urbanization cost. It also claims the best use of existing buried water infrastructure (BWI) (i.e., drinking water, wastewater, and stormwater) to meet the demand for water services. However, cities are facing several challenges due to increased densification. Urban densification inherits various environmental and health impacts, such as air pollution, congestion, urban heat island effects, loss of tree canopy, and traffic accidents. Furthermore, it is imposing continuous pressure on the existing BWI. More specifically, the challenges related to BWI include improper urban water supply and drainage services. All growing cities around the world are facing challenges in providing and maintaining the adequate performance of BWI. This research developed a decision support system to identify, predict, and improve the performance of BWI under urban densification. The research entails four phases. Phase 1 identified the impacts of densification and proposed a conceptual model, which provides a template to assess the performance. Phase 2 identified performance indicators (PIs) and established a self and comparative performance assessment model to evaluate the integrated level of service (ILOS) index of BWI. Phase 3 adopted a hybrid approach using empirical models to conduct the temporal analysis. Phase 4 developed an optimization model to identify optimal levels of the control PIs (CPIs). The results of this research will provide a foundation for enhanced decision-making to set performance standards at different levels of BWI hierarchy. Moreover, the proposed decision support system can provide best management practices to perform trade-offs between BWI performance and cost while mitigating the impacts of densification for sustainable development.

description: In this paper, we prove a new identity for values of the Hurwitz zeta function which contains as particular cases Koecher's identity for odd zeta values, the Bailey-Borwein-Bradley identity for even zeta values and many other interesting formulas related to values of the Hurwitz zeta function. We also get an extension of the bivariate identity of Cohen to values of the Hurwitz zeta function. The main tool we use here is a construction of new Markov-WZ pairs.

description: Equilibrium magnetization distribution of the vortex state magnetic nanoparticle is affected by the influence of the spin-transfer torque: an off-center out--of--plane vortex appears in the case of the disk shape particle and pure planar vortex in the case of asymmetric ring shape particle. The spin current causes extra out-of-plane magnetization structures identical to well known dip structures for the moving vortex. The shape of the dip structure depends on the current strength and value of the off-center displacement and it does not depend on the vortex polarity. The critical current depends on the nanodot thickness.

description: Photographs from Mecca in an Era of Mass- and Fast Mobility, Rukayyah Reichling (ESR 13) Mecca may be considered the geographical and spiritual centre of Islam. The city’s sanctity stems from the presence of the sanctuary of the Ka’ba at its heart, which on nineteen different occasions in the Qur’an has been referred to as al-masjid al-haram. According to Islamic tradition, the Ka’ba, or baitullah, was originally built by the Prophet Abraham as the first place of worship to the One God. Its position determines the qibla, the direction of prayer for Muslims around the world. Places in and around Mecca, the “mother of cities”, are furthermore the destination of the small and big Muslim pilgrimages. Considering the city’s sanctity and that the paths of pilgrims from broad regions of the Islamic world meet in Mecca, it is little astonishing that in the early tradition of map-making, Muslim cartographers frequently placed Mecca at the geographical centre of the world.

description: Permittivity tensors of arbitrary shaped invisibility devices are obtained using effective medium approach in general relativity. As special cases, analytical expressions for the permittivity tensors of invisibility cloaks for the elliptic cylinder, prolate spheroid, and the confocal paraboloid geometry are derived. In the case of elliptic cylinder, we found that the point of infinite light speed in the electromagnetic space becomes two points in the physical space in the zz component of the permittivity tensor. This result is different from the case of perfect cylinder in which there is a line of cloak at which the speed of light becomes infinite. In the cases of prolate spheroid and confocal paraboloid, the point of infinite light speed in the electromagnetic space becomes line in the physical space for the first two tensor components and the third component of the permittivity tensor becomes singular at the line of cloak.
Neuroprotective effect of sigma-1 receptor and activin A on synaptic function and calcium handling in Huntington disease
Creators: name: Nassrallah, Wissam
Publisher: name: University of British Columbia
Year: 2022

description: Huntington disease (HD) is a monogenic disorder with autosomal dominant inheritance. In HD patients, neurons in the striatum and cortex degenerate, leading to motor and cognitive disorders. Dysregulation of synaptic function and calcium handling is common in many neurodegenerative diseases. N-methyl-D-aspartate (NMDA) receptor function is enhanced at extrasynaptic sites, altering the balance of calcium-dependent neuronal survival vs. death signalling pathways. Another important level of calcium regulation is at the endoplasmic reticulum (ER), and this regulation is abnormal in HD. The ER is also suggested to be involved in nuclear calcium signalling, and I hypothesise that this signalling pathway is altered in HD. Sigma-1 receptors (S1Rs) – proteins located on the ER – play an important role in calcium regulation and thus gene transcription. Interestingly, activating S1Rs has been shown to normalise this ER calcium handling and restore synaptic function in HD mouse models. Furthermore, recent work has shown that overexpression of Activin A, a secreted protein whose transcription is nuclear-calcium-dependent, reduces toxic extrasynaptic NMDA receptor signalling in the hippocampus. The goal of this project is to determine the link between S1Rs, calcium handling, Activin A, and synaptic function to better understand the pathophysiological mechanisms of HD and to find new potential treatments. Neuronal cultures, imaging techniques, behavioural assessment, and electrophysiology were used to investigate these processes in a mouse model of HD. Our data shows contributions of different calcium channels to nuclear calcium signalling. Calcium imaging also suggests impairments in nuclear calcium signalling in HD striatal medium-sized spiny neurons in co-culture with cortical neurons, which was not corrected by treatment with S1R agonists. Furthermore, our data show that Activin A is decreased in HD culture media, and its overexpression normalises extrasynaptic NMDA receptor expression. Moreover, early injection of an Activin A AAV virus into the striatum led to a significant improvement in a motor coordination task at an age when HD mice are known to show impairment. This project has elucidated therapeutic benefits of Activin A in the treatment of HD; more research is needed to understand Activin A’s mechanism of action and further explore its potential benefits in other neurodegenerative diseases.
