Differentiation of Planetesimals and the Thermal Consequences of Melt Migration

description: We model the heating of a primordial planetesimal by decay of the short-lived radionuclides Al-26 and Fe-60 to determine (i) the timescale on which melting will occur; (ii) the minimum size of a body that will produce silicate melt and differentiate; (iii) the migration rate of molten material within the interior; and (iv) the thermal consequences of the transport of Al-26 in partial melt. Our models incorporate results from previous studies of planetary differentiation and are constrained by petrologic (i.e. grain size distributions), isotopic (e.g. Pb-Pb and Hf-W ages) and mineralogical properties of differentiated achondrites. We show that formation of a basaltic crust via melt percolation was limited by the formation time of the body, matrix grain size and viscosity of the melt. We show that low viscosity (< 1 Pa-s) silicate melt can buoyantly migrate on a timescale comparable to the mean life of Al-26. The equilibrium partitioning of Al into silicate partial melt and the migration of that melt acts to dampen internal temperatures. However, subsequent heating from the decay of Fe-60 generated melt fractions in excess of 50%, thus completing differentiation for bodies that accreted within 2 Myr of CAI formation (i.e. the onset of isotopic decay). Migration and concentration of Al-26 into a crust results in remelting of that crust for accretion times less than 2 Myr and for bodies >100 km in size. Differentiation would be most likely for planetesimals larger than 20 km in diameter that accreted within ~2.7 Myr of CAI formation.

description: The long-term distributions of trajectories of a flow are described by invariant densities, i.e. fixed points of an associated transfer operator. In addition, global slowly mixing structures, such as almost-invariant sets, which partition phase space into regions that are almost dynamically disconnected, can also be identified by certain eigenfunctions of this operator. Indeed, these structures are often hard to obtain by brute-force trajectory-based analyses. In a wide variety of applications, transfer operators have proven to be very efficient tools for an analysis of the global behavior of a dynamical system. The computationally most expensive step in the construction of an approximate transfer operator is the numerical integration of many short term trajectories. In this paper, we propose to directly work with the infinitesimal generator instead of the operator, completely avoiding trajectory integration. We propose two different discretization schemes; a cell based discretization and a spectral collocation approach. Convergence can be shown in certain circumstances. We demonstrate numerically that our approach is much more efficient than the operator approach, sometimes by several orders of magnitude.

description: We analyze the roles of initial correlations between the two-qubit system and a dissipative cavity on quantum discord dynamics of two qubits. Considering two initial system-cavity states, we show that the initial system-cavity correlations not only can initially increase the two-qubit quantum discord but also would lead to a larger long-time quantum discord asymptotic value. Moreover, quantum discord due to initial correlations is more robust than the case of the initial factorized state. Finally, we show the initial correlations' importance for dynamics behaviors of mutual information and classical correlation.

description: p-tert-Butyltetramercaptotetrathiacalix[4]arene was used as a coordination platform to synthesize and investigate gold(I) complexes with varying nuclearity. Aiming at the corresponding tetranuclear complex through salt metathesis it was found capable of binding a neutral, molecular TlCl entity by metallophilic interactions, as shown by structural and theoretical investigations. These Interactions lead to photoluminescence at low temperatures (see figure). The successive auration of p-tert-butyltetramercaptotetrathiacalix[4]arene, H4(MTC[4]), with gold(I) phosphine units was investigated. Through deprotonation with NaOMe, followed by salt metathesis reactions with (PR3)AuCl (R=Me, Ph) complexes with two and three [(PR3)Au]+ moieties could be prepared and isolated, namely [(Ph3PAu)2H2(MTC[4])] and [(Me3PAu)3H(MTC[4])]. In [(Me3PAu)3H(MTC[4])] two gold atoms already come close enough to undergo aurophilic interactions. To introduce a fourth [(PR3)Au]+ entity TlOEt had to be used for the deprotonation, which led to the finding that four gold atoms organised by the (MTC[4])4− coordination platform are able to bind and stabilize a TlCl entity, yielding [(Me3PAu)4TlCl(MTC[4])]. As evidenced by structural and theoretical investigations the binding occurs through strong metallophilic interactions, which lead to photoluminescence at low temperatures.

description: Multidimensional scaling (MDS) is a class of projective algorithms traditionally used in Euclidean space to produce two- or three-dimensional visualizations of datasets of multidimensional points or point distances. More recently however, several authors have pointed out that for certain datasets, hyperbolic target space may provide a better fit than Euclidean space. In this paper we develop PD-MDS, a metric MDS algorithm designed specifically for the Poincare disk (PD) model of the hyperbolic plane. Emphasizing the importance of proceeding from first principles in spite of the availability of various black box optimizers, our construction is based on an elementary hyperbolic line search and reveals numerous particulars that need to be carefully addressed when implementing this as well as more sophisticated iterative optimization methods in a hyperbolic space model.

description: The discovery of multi-planet extrasolar systems has kindled interest in using their orbital evolution as a probe of planet formation. Accurate descriptions of planetary orbits identify systems which could hide additional planets or be in a special dynamical state, and inform targeted follow-up observations. We combine published radial velocity data with Markov Chain Monte Carlo analyses in order to obtain an ensemble of masses, semimajor axes, eccentricities and orbital angles for each of 5 dynamically active multi-planet systems: HD 11964, HD 38529, HD 108874, HD 168443, and HD 190360. We dynamically evolve these systems using 52,000 long-term N-body integrations that sample the full range of possible line-of-sight and relative inclinations, and we report on the system stability, secular evolution and the extent of the resonant interactions. We find that planetary orbits in hierarchical systems exhibit complex dynamics and can become highly eccentric and maybe significantly inclined. Additionally we incorporate the effects of general relativity in the long-term simulations and demonstrate that can qualitatively affect the dynamics of some systems with high relative inclinations. The simulations quantify the likelihood of different dynamical regimes for each system and highlight the dangers of restricting simulation phase space to a single set of initial conditions or coplanar orbits.

Lowering the energy consumption of zinc electrowinning by electrocatalysis of the oxygen evolution reaction using manganese oxides
Creators: name: Arfania, Sheida
Publisher: name: University of British Columbia
Year: 2020

description: Zinc is employed in a wide range of commercial applications including galvanizing iron and steel and production of various metal alloys. In hydrometallurgical processes, zinc electrowinning from sulfate-based electrolytes is the last step of zinc extraction in which high purity metallic zinc is electrodeposited from a highly acidic solution on an aluminum cathode. The electrowinning stage is very energy-intensive and responsible for approximately 60% of the power requirement of a zinc refinery. Inside the electrowinning cell, oxygen evolution reaction (OER) overpotential on conventional lead-silver (Pb-Ag) anodes contributes to nearly 25% of the overall cell potential and places a heavy financial burden on zinc refining plants. Thus, improving the energy efficiency of electrowinning by lowering the OER overpotential is of primary significance to the zinc refineries. This study aimed to develop and evaluate novel anodes in order to lower the OER overpotential within the zinc electrowinning process. The novel anodes were prepared by electrodeposition of manganese oxides (MnOx) on industrially provided Pb-Ag substrate using various potentiodynamic and galvanostatic polarization techniques. The anodic electrocatalytic activity of the baseline and MnOx electrodeposited Pb-Ag electrodes was investigated in a manganese (II)-containing sulfuric acid electrolyte using linear scan voltammetry and 72-hour galvanostatic electrolysis at 500 amperes per meter squared current density. Additionally, the baseline and novel anodes were studied within the full-cell electrowinning setup by the means of 24-hour galvanostatic electrolysis at 500 amperes per meter squared current density. The electrolyte composition and operating conditions were selected such that to be directly applicable to the industrial zinc electrowinning process. The MnOx electrodeposited Pb-Ag anodes reduced the OER overpotential by a maximum of 155 and 113 mV in the absence and presence of chloride ions. Investigation of the novel electrodes in the full-cell zinc electrowinning operation corroborated the half-cell experiments, revealing a maximum of 133 mV reduction in overall cell potential. The surface morphology and elemental composition of the novel anodes were investigated using SEM/EDX, XRD, and ICP-OES. This work demonstrated that the MnOx electrodeposited Pb-Ag anodes reveal improved electrocatalytic activity and have great capacity to lower the energy consumption of the conventional zinc electrowinning process.

description: In this paper we derive the Spitzer IRAC band period-luminosity (P-L) relations for the Small Magellanic Cloud (SMC) Cepheids, by matching the Spitzer archival SAGE-SMC data with the OGLE-III SMC Cepheids. We find that the 3.6micron and 4.5micron band P-L relations can be better described using two P-L relations with a break period at log(P)=0.4: this is consistent with similar results at optical wavelengths for SMC P-L relations. The 5.8micron and 8.0micron band P-L relations do not extend to sufficiently short periods to enable a similar detection of a slope change at log(P)=0.4. The slopes of the SMC P-L relations, for log(P)>0.4, are consistent with their LMC counterparts that were derived from a similar dataset. They are also in agreement with those obtained from a small sample of Galactic Cepheids with parallax measurements.

description: It is shown that when the gauge-invariant Bohr-Rosenfeld commutators of the free electromagnetic field are applied to the expressions for the linear and angular momentum of the electromagnetic field interpreted as operators then, in the absence of electric and magnetic charge densities, these operators satisfy the canonical commutation relations for momentum and angular momentum. This confirms their validity as operators that can be used in quantum mechanical calculations of angular momentum.

description: We present a possible construction of coherent states on the unit circle as configuration space. In our approach the phase space is the product Z x S^1. Because of the duality of canonical coordinates and momenta, i.e. the angular variable and the integers, this formulation can also be interpreted as coherent states over an infinite periodic chain. For the construction we use the analogy with our quantization over a finite periodic chain where the phase space was Z_M x Z_M. Properties of the coherent states constructed in this way are studied and the coherent states are shown to satisfy the resolution of unity.

description: Let $\{f_{a,b}\}$ be the (original) Hénon family. In this paper, we show that, for any $b$ near $0$, there exists a closed interval $J_b$ which contains a dense subset $J'$ such that, for any $a\in J'$, $f_{a,b}$ has a quadratic homoclinic tangency associated with a saddle fixed point of $f_{a,b}$ which unfolds generically with respect to the one-parameter family $\{f_{a,b}\}_{a\in J_b}$. By applying this result, we prove that $J_b$ contains a residual subset $A_b^{(2)}$ such that, for any $a\in A_b^{(2)}$, $f_{a,b}$ admits the Newhouse phenomenon. Moreover, the interval $J_b$ contains a dense subset $\tilde A_b$ such that, for any $a\in \tilde A_b$, $f_{a,b}$ has a large homoclinic set without SRB measure and a small strange attractor with SRB measure simultaneously. Dedicated to the memory of Floris Takens (Nov. 12, 1940 - Jun. 20, 2010).

description: We studied the effect of primordial non-Gaussianity with varied bispectrum shapes on the number counts of signal-to-noise peaks in wide field cosmic shear maps. The two cosmological contributions to this particular weak lensing statistic, namely the chance projection of Large Scale Structure and the occurrence of real, cluster-sized dark matter halos, have been modeled semi-analytically, thus allowing to easily introduce the effect of non-Gaussian initial conditions. We performed a Fisher matrix analysis by taking into account the full covariance of the peak counts in order to forecast the joint constraints on the level of primordial non-Gaussianity and the amplitude of the matter power spectrum that are expected by future wide field imaging surveys. We find that positive-skewed non-Gaussianity increases the number counts of cosmic shear peaks, more so at high signal-to-noise values, where the signal is mostly dominated by massive clusters as expected. The increment is at the level of ~1 for f_NL=10 and ~10 for f_NL=100 for a local shape of the primordial bispectrum, while different bispectrum shapes give generically a smaller effect. For a future survey on the model of the proposed ESA space mission Euclid and by avoiding the strong assumption of being capable to distinguish the weak lensing signal of galaxy clusters from chance projection of Large Scale Structures we forecasted a 1-sigma error on the level of non-Gaussianity of ~30-40 for the local and equilateral models, and of ~100-200 for the less explored enfolded and orthogonal bispectrum shapes.

Improved Bounds for $r$-Identifying Codes of the Hex Grid

description: For any positive integer $r$, an $r$-identifying code on a graph $G$ is a set $C\subset V(G)$ such that for every vertex in $V(G)$, the intersection of the radius-$r$ closed neighborhood with $C$ is nonempty and pairwise distinct. For a finite graph, the density of a code is $|C|/|V(G)|$, which naturally extends to a definition of density in certain infinite graphs which are locally finite. We find a code of density less than $5/(6r)$, which is sparser than the prior best construction which has density approximately $8/(9r)$.

description: Come spesso succede, sono gli esempi negativi a stigmatizzare un’intera comunità, facendoci dimenticare che la maggior parte delle persone giungono nel nostro paese per fuggire dalla povertà, cercare un futuro dignitoso o cercare protezione e non per creare problemi. Ho iniziato questo percorso informandomi sulla storia e le varie tipologie di migrazione internazionali e locali, collaborando con Croce Rossa ho appreso nozioni sul suo operato, ho potuto intervistare alcuni suoi collaboratori ma soprattutto interagire con i ragazzi, raccogliere le loro storie e le varie tappe dei loro viaggi. Dopo una breve ricerca sui linguaggi visivi e dopo aver analizzato diversi casi studio sulla tematica, mi sono concentrata su quale potesse essere il modo migliore per riuscire a comunicare con la popolazione e trasmettere il messaggio che mi ero proposta. Dopo varie prove ho concluso che il modo migliore per poter raggiungere il mio obiettivo era quello di creare un’installazione composta da due applicazioni web. La prima che sotto forma di gioco a quiz fornisca informazioni sulla migrazione e sull’operato di Croce Rossa, mentre la seconda per raccontare le storie e le tappe dei viaggi di quattro ragazzi migranti selezionati, e offrire la possibilità di confrontarle con le storie di altrettanti coetanei locali.

description: We introduce an operational entanglement classification of symmetric mixed states for an arbitrary number of qubits based on stochastic local operations assisted with classical communication (SLOCC operations). We define families of SLOCC entanglement classes successively embedded into each other, we prove that they are of non-zero measure, and we construct witness operators to distinguish them. Moreover, we discuss how arbitrary symmetric mixed states can be realized in the lab via a one-to-one correspondence between well-defined sets of controllable parameters and the corresponding entanglement families.

Tomografo a microonde

description: Lo scopo della presente documentazione è quello di descrivere il lavoro svolto nella realizzazione del progetto di diploma, il quale consiste nello studio, simulazione e realizzazione di diverse tipologie di antenna in modo da poter ottimizzare un tomografo già esistente nel laboratorio TTHF SUPSI. La creazione di queste antenne è motivato dal fatto che il sistema non gode di un’ottima risoluzione e quindi necessita di più scansioni per ottenere un discreto risultato. Una volta ultimato il sistema permetterà la detezione precoce di eventuali carcinomi mammari, che rappresentano il 13.5% di decessi per tumori nelle donne. La rilevabilità di questo particolare carcinoma risulta difficile dal fatto che le scansioni a raggi X risultino troppo aggressive limitandone l’esecuzione ad un massimo di 2 scansioni annue. Il presente sistema lavora a frequenze molto più basse, da 1GHz a 8GHz, permettendo così di eseguire molte più scansioni annue per paziente e, di conseguenza, poter effettuare controlli più frequenti così da poter intervenire tempestivamente in caso di rilevamento di un carcinoma mammario. Abstract The purpose of this document is to describe the work carried out in the realization of the diploma project, which consists in the study, simulation and realization of different antenna types in order to optimize an existing tomograph developed on TTHF SUPSI laboratory. The develop of these antennas is motivated by the fact that the system does not have an excellent resolution and therefore requires more scans to obtain a good result. Once completed, the system will allow the early detection of possible breast cancer, which represent 13.5% of cancer deaths in women. The detectability of this particular cancer is difficult due to the fact that X-ray scans are too aggressive, limiting their execution to a maximum of 2 scans a year. The present system works at much lower frequencies, from 1GHz to 8GHz, thus allowing to perform many more annual scans per patient and, consequently, to carry out more frequent checks so as to intervene promptly in case of detection of a breast cancer.
Forgotten refugees : understanding the language and literacy practices of Afghan refugees in Pakistan

Publisher: name: University of British Columbia

description: Most refugees arriving in permanent resettlement countries, such as Canada, come from first asylum countries, or countries that refugees move to first to escape the crisis in their homelands. Refugees arrive in permanent resettlement countries with various educational experiences and these pre-settlement educational experiences have largely remained undocumented, a phenomenon Dryden-Peterson described as a “black box” (2016, p. 131). In light of this gap, the purpose of this study was to document the language and literacy practices of young Afghan refugees in Pakistan in their homes, at school, and in their community, and to describe their parents’/guardians’ beliefs about language and literacy. Informed by sociocultural theory and Bronfenbrenner’s ecological theory, this qualitative study used ethnographic methods and focused on four Afghan refugee children and their families over five months. Language and literacy events were observed and analyzed using Miles, Huberman, and Saldaña’s (2014) procedure for qualitative research. Findings showed the children spoke Pashto at home but used Urdu and Pashto in the community. At school, the children spoke English, Urdu, and Pashto, but reading and writing were only taught in English and Urdu. The children participated in various literacy activities at home, including engaging in storytelling and practicing religious supplications. The female children were successful in their schoolwork and, with some assistance, could read and write in Urdu and English. The male children, however, could not complete most assignments that required them to read and write in English or Urdu independently and relied on their classmates, teachers, and resources (e.g., posters) to complete those assignments. In the community, the female children tutored others with schoolwork, Quranic reading, or religious supplications. The male children attended Quranic lessons to practice Arabic words to prepare for reading the Quran. Parents/guardians valued literacy and languages highly. Many believed that reading allowed one to see and that literacy instilled manners in one. This study enhances our understanding of the literacy practices of one of the largest refugee groups in the world, about which little is known. Specifically, insights about their literacy and language practices as they relate to codeswitching or translanguaging, and literacy brokering are revealed.

Structures in compressible magnetoconvection and the nature of umbral dots

description: Structures seen in idealized numerical experiments on compressible magnetoconvection in an imposed strong vertical magnetic field show important differences from those detected in observations or realistic numerical simulations of sunspot umbrae. To elucidate the origin of these discrepancies, we present a series of idealized 3D compressible magnetoconvection experiments that differ from previous such experiments in several details, bringing them closer to realistic solar conditions. An initially vertical magnetic field B 0 is imposed on a time snapshot of fully developed solar-like turbulent convection in a layer bounded by a stable layer from above. Upon relaxation to a statistically steady state, the structure of the flow field and magnetic field is examined. Instead of the vigorous granular convection (GRC) well known to take place in magnetized or weakly magnetized convection, for high values of B0 heat is transported by small-scale convection (SSC) in the form of narrow, persistent convective columns consisting of slender upflows accompanied by adjacent downflow patches, which are reminiscent of the 'convectons' identified in earlier semianalytic models. For moderate field strengths, flux separation (FXS) is observed: isolated field-free inclusions of GRC are embedded in a strongly magnetized plasma with SSC. Between the SSC and FXS regimes, a transitional regime (F/S) is identified where convectons dynamically evolve into multiply segmented granular inclusions and back. Our results agree in some aspects more closely with observed umbral structures than earlier idealized models, because they do reproduce the strong localized, patchy downflows immediately adjacent to the narrow convective columns. Based on recent observations of umbral dots, we suggest that in some cases the conditions in sunspot umbrae correspond to the newly identified F/S transitional regime.

description: The present contribution covers results of numerical simulation of three-dimensional turbulent flow, arising under the action of buoyancy force, and heat transfer in a free-convection boundary layer on a vertical isothermal plate perturbed by transverse row of cylindrical obstacles of finite height. Computations were performed using ANSYS Fluent software package with the k-Ï SST model used for turbulence modeling. Solutions are obtained for three different cylinder heights and two different thermal boundary conditions on its surface. The analysis of complex vortex structures near the obstacles, including horseshoe vortices, as well as local friction and heat transfer, has been carried out.
