description: We study local moment formation for adatoms on bilayer graphene (BLG) within a mean-field theory of the Anderson impurity model. The wavefunctions of the BLG electrons induce strong particle-hole asymmetry and band dependence of the hybridization, which is shown to result in unusual features in the impurity model phase diagram. We also study the effect of varying the chemical potential, as well as varying an electric field perpendicular to the bilayer; the latter modifies the density of states of electrons in BLG and, more significantly, shifts the impurity energy. We show that this leads to regimes in the impurity phase diagram where local moments can be turned on or off by applying modest external electric fields. Finally, we show that the RKKY interaction between local moments can be varied by tuning the chemical potential (as has also been suggested in monolayer graphene) or, more interestingly, by tuning the electric field so that it induces changes in the band structure of BLG.

description: We consider a double scaling limit of the plane wave matrix model (PWMM), in which the gravity dual geometry of PWMM reduces to a class of spherical NS5-brane solutions. We identify the form of the scaling limit for the dual geometry of PWMM around a general vacuum and then translate the limit into the field theoretic language. We also show that the limit indeed exists at least in a certain planar 1/4-BPS sector of PWMM by using the localization computation analytically. In addition, we employ the hybrid Monte Carlo method to compute the matrix integral obtained by the localization method, near the parameter region where the supergravity approximation is valid. Our numerical results, which are considered to be the first computation of quantum loop correction to the Lin-Maldacena geometry, suggest that the double scaling limit exists beyond the planar sector.

description: Lopsidedness of the gaseous disk of spiral galaxies is a common phenomenon in disk morphology, profile and kinematics. Simultaneously, the asymmetry of a galaxy's stellar disk, in combination with other morphological parameters, has seen extensive use as an indication of recent merger or interaction in galaxy samples. Quantified morphology of stellar spiral disks is one avenue to determine the merger rate over much of the age of the Universe. In this paper, we measure the quantitative morphology parameters for the HI column density maps from the Westerbork observations of neutral Hydrogen in Irregular and SPiral galaxies (WHISP). These are Concentration, Asymmetry, Smoothness, Gini, M20, and one addition of our own, the Gini parameter of the second order moment (GM). Our aim is to determine if lopsided or interacting disks can be identified with these parameters. Our sample of 141 HI maps have all previous classifications on their lopsidedness and interaction. We find that the Asymmetry, M20, and our new GM parameter correlate only weakly with the previous morphological lopsidedness quantification. These three parameters may be used to compute a probability that an HI disk is morphologically lopsided but not unequivocally to determine it. However, we do find that that the question whether or not an HI disk is interacting can be settled well using morphological parameters. Parameter cuts from the literature do not translate from ultraviolet to HI directly but new selection criteria using combinations of Asymmetry and M20 or Concentration and M20, work very well. We suggest that future all-sky HI surveys may use these parameters of the column density maps to determine the merger fraction and hence rate in the local Universe with a high degree of accuracy.

description: The mergers of supermassive black hole binaries (SMBHBs) can serve as standard sirens: the gravitational wave (GW) analog of standard candles. The upcoming space-borne GW detectors will be able to discover such systems and estimate their luminosity distances precisely. Unfortunately, weak gravitational lensing can induce significant errors in the measured distance of these standard sirens at high redshift, severely limiting their usefulness as precise distance probes. The uncertainty due to weak lensing can be reduced if the lensing magnification of the siren can be estimated independently, a procedure called 'delensing'. With the help of up-to-date numerical simulations, here we investigate how much the weak-lensing errors can be reduced using convergence maps reconstructed from shear measurements. We also evaluate the impact of delensing on cosmological parameter estimation with bright standard sirens. We find that the weak-lensing errors for sirens at $z_s = 2.9$ can be reduced by about a factor of two on average, but to achieve this would require expensive ultra-deep field observations for every siren. Such an approach is likely to be practical in only limited cases, and the reduction in the weak-lensing error is therefore likely to be insufficient to significantly improve the cosmological parameter estimation. We conclude that performing delensing corrections is unlikely to be worthwhile, in contrast to the more positive expectations presented in previous studies. For delensing to become more practicable and useful in the future will require significant improvements in the resolution/depth of weak-lensing surveys and/or the methods to reconstruct convergence maps from these surveys.

description: Context: Multiwavelength observations of gamma-ray burst prompt and afterglow emission are a key tool to disentangle the various possible emission processes and scenarios proposed to interpret the complex gamma-ray burst phenomenology. Aims: We collected a large dataset on GRB060908 in order to carry out a comprehensive analysis of the prompt emission as well as the early and late afterglow. Methods: Data from Swift-BAT, -XRT and -UVOT together with data from a number of different ground-based optical/NIR and millimeter telescopes allowed us to follow the afterglow evolution from about a minute from the high-energy event down to the host galaxy limit. We discuss the physical parameters required to model these emissions. Results: The prompt emission of GRB060908 was characterized by two main periods of activity, spaced by a few seconds of low intensity, with a tight correlation between activity and spectral hardness. Observations of the afterglow began less than one minute after the high-energy event, when it was already in a decaying phase, and it was characterized by a rather flat optical/NIR spectrum which can be interpreted as due to a hard energy-distribution of the emitting electrons. On the other hand, the X-ray spectrum of the afterglow could be fit by a rather soft electron distribution. Conclusions: GRB060908 is a good example of a gamma-ray burst with a rich multi-wavelength set of observations. The availability of this dataset, built thanks to the joint efforts of many different teams, allowed us to carry out stringent tests for various interpretative scenarios showing that a satisfactorily modeling of this event is challenging. In the future, similar efforts will enable us to obtain optical/NIR coverage comparable in quality and quantity to the X-ray data for more events, therefore opening new avenues to progress gamma-ray burst research.

description: We address the low-energy effective Hamiltonian of electron doped d0 perovskite semiconductors in cubic and tetragonal phases using the k*p method. The Hamiltonian depends on the spin-orbit interaction strength, on the temperature-dependent tetragonal distortion, and on a set of effective-mass parameters whose number is determined by the symmetry of the crystal. We explain how these parameters can be extracted from angle resolved photo-emission, Raman spectroscopy, and magneto-transport measurements and estimate their values in SrTiO3.

BRCA1 regulates the PLK1-mediated spindle positioning pathway that promotes luminal features and may suppress tumorigenesis in mammary epithelial cells
Creators: name: He, Zhengcheng
Publisher: name: University of British Columbia
Year: 2022

description: Female carriers of mutations in Breast cancer, early onset 1 (BRCA1) show an elevated risk to develop breast cancers that resemble the primitive and proliferative cells of the mammary gland. BRCA1 is proposed to regulate the homeostasis of mammary progenitor cells, but its actions are not completely known. I hypothesize that BRCA1 regulates the positioning of the mitotic spindle, which ultimately controls the luminal features displayed in the progeny cells produced. I first used lentivirus transduction to silence BRCA1 expression in human mammary epithelial cells, including immortal MCF10A cells and primary cells isolated from reduction mammoplasty tissues. I found that the loss of BRCA1 function perturbed the cell division axis, which induced aneuploidy in progeny cells, reduced colony output, and perturbed the expression of luminal features. Mechanistically, a dynein-based pathway was disturbed by loss of BRCA1 function. I then studied the ex vivo growth of human mammary cells isolated directly from female carriers with pathogenic BRCA1 mutations. These progenitor-derived cells exhibited lower BRCA1 levels, higher radiosensitivity, and changes to the cell division axis. I used genome editing in MCF10A cells to model and study heterozygous BRCA1 mutations. These studies identified low BRCA1 expression and an inability to correctly orient the cell division axis in cells encoding pathogenic mutations. Subsequent proteomic analysis indicated PLK1 hyperactivity and treatment with a PLK1 inhibitor recovered the cell division axis and the acquisition of luminal features in primary mammary cells isolated from Brca1 mutant mice or female carriers with pathogenic BRCA1 mutations. Finally, I examined the tumorigenic processes that are altered through tissue-specific overexpression of a BRCA1 modifier, termed HMMR. From BLG-Cre;Brca1f/f;Trp53+/- mammary tissues, I isolated and studied epithelial cells that showed a loss of genome stability and activation of cGAS-STING and NF-κB signaling. HMMR overexpression increased the expression of immune-related genes that are known to recruit macrophages and promote a pro-tumorigenic microenvironment. Together, these research findings indicate BRCA1 controls mitotic spindle orientation. The disruption of this mechanism may underlie the changes observed in mammary epithelial cells and the increased risk to develop basal-like breast cancer that is observed in female carriers of BRCA1 mutations.

Entropic Corrections to Friedmann Equations

description: Recently, Verlinde discussed that gravity can be understood as an entropic force caused by changes in the information associated with the positions of material bodies. In the Verlinde's argument, the area law of the black hole entropy plays a crucial role. However, the entropy-area relation can be modified from the inclusion of quantum effects, motivated from the loop quantum gravity. In this note, by employing this modified entropy-area relation, we derive corrections to Newton's law of gravitation as well as modified Friedman equations by adopting the viewpoint that gravity can be emerged as an entropic force. Our study further supports the universality of the log correction and provides a strong consistency check on Verlinde's model.

description: We consider the evolution of a system of chargeless and massless particles in an anisotropic space-time given by the Bianchi type I metric. Specializing to the axis-symmetric case, we derive the framework of anisotropic hydrodynamics from the Boltzmann equation in the relaxation-time approximation. We consider the case of the axis-symmetric Kasner metric and study the approach to the emergent attractor in near and far-off-equilibrium regimes. Further, by relaxing the Kasner conditions on metric coefficients, we study the effect of expansion geometries on the far-off-equilibrium attractor and discuss its implications in the context of relativistic heavy-ion collisions.

description: We propose a simple scenario which explains the observed matter-antimatter imbalance and the origin of dark matter in the Universe. We use the Einstein-Cartan-Sciama-Kibble theory of gravity which naturally extends general relativity to include the intrinsic spin of matter. Spacetime torsion produced by spin generates, in the classical Dirac equation, the Hehl-Datta term which is cubic in spinor fields. We show that under a charge-conjugation transformation this term changes sign relative to the mass term. A classical Dirac spinor and its charge conjugate therefore satisfy different field equations. Fermions in the presence of torsion have higher energy levels than antifermions, which leads to their decay asymmetry. Such a difference is significant only at extremely high densities that existed in the very early Universe. We propose that this difference caused a mechanism, according to which heavy fermions existing in such a Universe and carrying the baryon number decayed mostly to normal matter, whereas their antiparticles decayed mostly to hidden antimatter which forms dark matter. The conserved total baryon number of the Universe remained zero.

Quantum irreversibility of quasistatic protocols for finite-size quantized systems

description: Quantum mechanically, a driving process is expected to be reversible in the quasistatic limit, also known as the adiabatic theorem. This statement stands in opposition to classical mechanics, where a mix of regular and chaotic dynamics implies irreversibility. A paradigm for demonstrating the signatures of chaos in quantum irreversibility is a sweep process whose objective is to transfer condensed bosons from a source orbital. We show that such a protocol is dominated by an interplay of adiabatic-shuttling and chaos-assisted depletion processes. The latter is implied by interaction terms that spoil the Bogoliubov integrability of the Hamiltonian. As the sweep rate is lowered, a crossover to a regime that is dominated by quantum fluctuations is encountered, featuring a breakdown of quantum-to-classical correspondence. The major aspects of this picture are not captured by the common two-orbital approximation, which implies failure of the familiar many-body Landau-Zener paradigm.

description: Estimation algorithms, such as the sliding window filter, produce an estimate and uncertainty of desired states. This task becomes challenging when the problem involves unobservable states. In these situations, it is critical for the algorithm to ``know what it doesn't know'', meaning that it must maintain the unobservable states as unobservable during algorithm deployment. This letter presents general requirements for maintaining consistency in sliding window filters involving unobservable states. The value of these requirements for designing navigation solutions is experimentally shown within the context of visual-inertial SLAM making use of IMU preintegration.

description: This is a draft of a book about algorithms for performing arithmetic, and their implementation on modern computers. We are concerned with software more than hardware - we do not cover computer architecture or the design of computer hardware. Instead we focus on algorithms for efficiently performing arithmetic operations such as addition, multiplication and division, and their connections to topics such as modular arithmetic, greatest common divisors, the Fast Fourier Transform (FFT), and the computation of elementary and special functions. The algorithms that we present are mainly intended for arbitrary-precision arithmetic. They are not limited by the computer word size, only by the memory and time available for the computation. We consider both integer and real (floating-point) computations. The book is divided into four main chapters, plus an appendix. Our aim is to present the latest developments in a concise manner. At the same time, we provide a self-contained introduction for the reader who is not an expert in the field, and exercises at the end of each chapter.

description: A set of 12 abietane diterpene derivatives have been synthesised by the Ugi-four component reaction (Ugi-4CR) and tested for cytotoxicity and activity against influenza virus A/Puerto Rico/8/34 (H1N1) and SARS-CoV-2 pseudovirus. Five dipeptide derivatives demonstrated a selectivity index (SI) higher than 10 and IC50 values from 2 to 32 μM against influenza virus. Compound 11 was found to be a lead with SI of 200, and time-of-addition experiments showed the viral entry into the cell and the binding of the virus to the receptor as a possible target. Compound 7 was the only one showed weak anti-SARS-CoV-2 activity with EC50 value of 80.96 µM. Taken together, our data suggest the potency of diterpene acids-Ugi products as new effective anti-influenza compounds.

description: We present evidence that the strong electron-electron interactions in gapped carbon nanotubes lead to finite hierarchies of excitons within a given nanotube subband. We study these hierarchies by employing a field theoretic reduction of the gapped carbon nanotube permitting electron-electron interactions to be treated exactly. We analyze this reduction by employing a Wilsonian-like numerical renormalization group. We are so able to determine the gap ratios of the one-photon excitons as a function of the effective strength of interactions. We also determine within the same subband the gaps of the two-photon excitons, the single particle gaps, as well as a subset of the dark excitons. The strong electron-electron interactions in addition lead to strongly renormalized dispersion relations where the consequences of spin-charge separation can be readily observed.

description: The objective of this Federal Highway Administration (FHWA) project was to determine the safety effectiveness of low- to medium-cost engineering countermeasures in reducing non-motorist (i.e., pedestrian) fatalities and injuries at controlled and uncontrolled intersections. The project started with a survey to identify the use of pedestrian treatments and preference for which treatments need a CMF. Using the survey findings, the FHWA stakeholder engagement working group set the research direction for investigating the relationship of intersection corner radius design with crashes and turning speed.
L’integrazione delle ICT nella didattica del Latino

Year: 2012

description: Il fatto di percepire il Latino come una disciplina vetusta e superata porta molti studenti a perdere interesse e motivazione nello studio, decidendo di abbandonarlo del tutto. Tuttavia, poiché nell’insegnamento un ruolo centrale è giocato dalla modalità di trasmissione – o meglio, di comunicazione – dei saperi, si è cercato di sperimentare una modalità didattica volta a insegnare la disciplina mediante l’integrazione delle ICT, ovvero delle information and communications technology, nella convinzione che da ciò derivi un apprendimento più efficace rispetto a quello derivante dalla lezione classica. Ho attuato una ricerca-azione basata sull’analisi di dati quantitativi e qualitativi, svolgendo cicli di lezioni alternati senza e mediante l’impiego delle ICT. Al termine di ogni ciclo ho somministrato ai discenti un test di verifica sommativa. A distanza di un mese ho riproposto lo stesso test, per valutare la persistenza delle conoscenze. Terminati i cicli di lezioni, ho svolto i confronti tra i risultati emersi per dimostrare, o sconfessare, l’ipotesi iniziale: la maggiore efficacia della didattica fondata sulle ICT rispetto alla lezione classica. I dati emersi dimostrano che le conoscenze acquisite mediante le ICT restano più impresse, e più a lungo, – con una perdita inferiore in termini percentuali – nelle menti degli studenti, che non quelle raggiunte mediante lezioni classiche.

description: Speech-centric machine learning systems have revolutionized many leading domains ranging from transportation and healthcare to education and defense, profoundly changing how people live, work, and interact with each other. However, recent studies have demonstrated that many speech-centric ML systems may need to be considered more trustworthy for broader deployment. Specifically, concerns over privacy breaches, discriminating performance, and vulnerability to adversarial attacks have all been discovered in ML research fields. In order to address the above challenges and risks, a significant number of efforts have been made to ensure these ML systems are trustworthy, especially private, safe, and fair. In this paper, we conduct the first comprehensive survey on speech-centric trustworthy ML topics related to privacy, safety, and fairness. In addition to serving as a summary report for the research community, we point out several promising future research directions to inspire the researchers who wish to explore further in this area.

description: Using a sample of 92 UV continuum-selected, spectroscopically identified galaxies with = 2.65, all of which have been imaged in the Ly-a line with extremely deep narrow-band imaging, we examine galaxy Ly-a emission profiles to very faint surface brightness limits. The galaxies are representative of spectroscopic samples of LBGs at similar redshifts in terms of apparent magnitude, UV luminosity, inferred extinction, and star formation rate, and were selected without regard to Ly-a emission properties. We use extremely deep stacks of UV continuum and Ly-a emission line images to show that all sub-samples exhibit diffuse Ly-a emission to radii of at least 10" (80 physical kpc), including galaxies whose spectra exhibit Ly-a in net absorption. The intensity scaling, but not the surface brightness distribution, is strongly correlated with the emission observed in the central ~1". The characteristic scale length for Ly-a line emission exceeds that of the UV continuum light for the same galaxies by factors of at least 5-10, regardless of the spectral morphology of Ly-a. Including the extended Ly-a halos increases the total Ly-a flux [and rest equivalent width W_0(Lya)] by an average factor of 5. We argue that most, if not all, of the observed Ly-a emission in the diffuse halos originates in the galaxy H II regions and is scattered in our direction by H I gas in the galaxy's circum-galactic medium (CGM). We show that whether or not a galaxy is classified as a giant "Lyman-a Blob" (LAB) depends sensitively on the Ly-a surface brightness threshold reached by an observation. Accounting for diffuse Ly-a halos, all LBGs would be LABs if surveys were routinely sensitive to 10 times lower surface brightness thresholds; also, essentially all LBGs would qualify as LAEs (W_0(Lya) > 20 A).

description: Single-component ultracold atomic Fermi gases are usually described using noninteracting many-fermion models. However, recent experiments reached a regime where $p$-wave interactions among identical fermionic atoms are important. In this paper, we employ variational and fixed-node diffusion Monte Carlo simulations to investigate the ground-state properties of single-component Fermi gases with short-range repulsive interactions. We determine the zero-temperature equation of state, and elucidate the roles played by the $p$-wave scattering volume and the $p$-wave effective range. A comparison against recently derived second-order perturbative results shows good agreement in a broad range of interaction strength. We also compute the quasiparticle effective mass, and we confirm the perturbative prediction of a linear contribution in the $p$-wave scattering volume, while we find significant deviations from the beyond-mean-field perturbative result, already for moderate interaction strengths. Finally, we determine ground-state energies for two-component unpolarized Fermi gases with both interspecies and intraspecies hard-sphere interactions, finding remarkable agreement with a recently derived fourth-order expansion that includes $p$-wave contributions.

description: A general relation for the dependence of nearest neighbor degree correlations on degree is derived. Dependence of local clustering on degree is shown to be the sole determining factor of assortative versus disassortative mixing in networks. The characteristics of networks derived from spatial atomic/molecular systems exemplified by self-organized residue networks and block copolymers, atomic clusters and well-compressed polymeric melts are studied. Distributions of statistical properties of the networks are presented. For these densely-packed systems, assortative mixing in the network construction is found to apply, and conditions are derived for a simple linear dependence. Together, these measures (i) reveal patterns that are common to close-packed clusters of atoms/molecules, (ii) identify the type of surface effects prominent in different systems, and (iii) associate fingerprints that may be used to classify networks with varying types of correlations.

Understanding the diversity, biochemistry, and biological role of endo-glucanase 16 enzymes in the context of plant evolution
Creators: name: Behar, Hila
Publisher: name: University of British Columbia
Year: 2022

description: A defining feature of plants, the plant cell wall is an essential structure that provides mechanical support, cell shape, and protection from pathogens and the environment. Cell walls are dynamic structures that are composed of a network of crystalline cellulose microfibrils, amorphous polysaccharides, and structural proteins. The synthesis, maintenance, and modification of the plant cell wall polysaccharides are carried out by carbohydrate active-enzymes (CAZymes). Xyloglucan endotransglycosylase/hydrolase (XTH) are secreted cell wall enzymes that restructure the cell wall matrix glycan, xyloglucan, thereby facilitating cell wall remodelling and growth. The plant endo-glucanase 16 (EG16) enzymes were recently identified as a unique clade that is structurally and functionally intermediate between the bacterial mixed-linkage β(1,3)/(1,4)-glucanases and the plant XTHs in glycoside hydrolase family 16 (GH16). Correspondingly, EG16 members were broadly specific towards the cell wall polysaccharides mixed-linkage β-glucan (MLG) and xyloglucan, as well as soluble cellulosic substrates. Although EG16 activity and protein structure have been demonstrated, their biological role is unknown. This thesis employs a multi-disciplinary approach to the characterization of the newly designated EG16 group. A comprehensive census of the publicly available genome and transcriptomes showed that EG16 orthologs were found in all plant clades spanning nearly 500 million years of evolution. Notably, the presence of EG16 orthologs observed in the charophyte green algae species that are the most phylogenetically distant from angiosperms, support that EG16-like genes are ancestors to extant EG16 and XTH genes. EG16 substrate specificities, primary hydrolysis site, and digest products are consistent between vastly different plant species. Elucidation of the biological role of EG16 in the moss Physcomitrella patens and a hybrid poplar species, two different distantly related land plants, show gene expression in young tissues and leaderless cell wall localization. In P. patens, EG16 deletion yielded larger plants that senesced earlier than wild-type, whereas, in poplar, downregulation did not affect growth. This thesis serves as a foundation for the EG16 clade and informs their evolutionary history, conserved activity, cell wall localization, and involvement in growth. The research opens the door to investigate unexplored topics such as the EG16 specific secretion mechanism and their role in MLG-containing cell walls.
