description: We consider a recently proposed model to understand the rigidity transition in confluent tissues and we derive the dynamical mean field theory (DMFT) equations that describes several types of dynamics of the model in the thermodynamic limit: gradient descent, thermal Langevin noise and active drive. In particular we focus on gradient descent dynamics and we integrate numerically the corresponding DMFT equations. In this case we show that gradient descent is blind to the zero temperature replica symmetry breaking (RSB) transition point. This means that, even if the Gibbs measure in the zero temperature limit displays RSB, this algorithm is able to find its way to a zero energy configuration. We include a discussion on possible extensions of the DMFT derivation to study problems rooted in high-dimensional regression and optimization via the square loss function.

description: The emission from a gamma-ray burst (GRB) photosphere can give rise to a variety of spectral shapes. The spectrum can retain the shape of a Planck function or it can be broadened and have the shape of a Band function. This fact is best illustrated by studying GRB090902B: The main gamma-ray spectral component is initially close to a Planck function, which can only be explained by emission from the jet photosphere. Later, the same component evolves into a broader Band function. This burst thus provides observational evidence that the photosphere can give rise to a non-thermal spectrum. We show that such a broadening is most naturally explained by subphotospheric dissipation in the jet. The broadening mainly depends on the strength and location of the dissipation, on the magnetic field strength, and on the relation between the energy densities of thermal photons and of the electrons. We suggest that the evolution in spectral shape observed in GRB090902B is due to a decrease of the bulk Lorentz factor of the flow, leading to the main dissipation becoming subphotospheric. Such a change in the flow parameters can also explain the correlation observed between the peak energy of the spectrum and low-energy power law slope, alpha, a correlation commonly observed in GRBs. We conclude that photospheric emission could indeed be a ubiquitous feature during the prompt phase in GRBs and play a decisive role in creating the diverse spectral shapes and spectral evolutions that are observed.

description: In the noisy intermediate-scale quantum era, variational algorithms have become a standard approach to solving quantum many-body problems. Here, we present variational quantum eigensolver (VQE) results of selected oxygen isotopes within the shell model description. The aim of the present work is to locate the neutron drip line of the oxygen chain using unitary coupled cluster (UCC) type ansatze with different microscopic interactions (DJ16, JISP16, and N3LO), in addition to a phenomenological USDB interaction. While initially infeasible to execute on contemporary quantum hardware, the size of the problem is reduced significantly using qubit tapering techniques in conjunction with custom circuit design and optimization. The optimal values of ansatz parameters from classical simulation are taken for the DJ16 interaction, and the tapered circuits are run on IonQ's Aria, a trapped-ion quantum computer. After applying gate error mitigation for three isotopes, we reproduced exact ground state energies within a few percent error. The post-processed results from hardware also clearly show $^{24}$O as the drip line nucleus of the oxygen chain. Future improvements in quantum hardware could make it possible to locate drip lines of heavier nuclei.

description: We investigate the harmonically trapped 2D fermionic systems with a effective spin-orbit coupling and intrinsic s-wave superfluidity under the local density approximation, and find that there is a critical value for Zeeman field. When the Zeeman field larger than the critical value, the topological superfluid phases emerge and coexist with the normal superfluid phase, topological phase separation, in the trapped region. Otherwise, the superfluid phase is topologically trivial.

description: The problems associated with a global increase in antibiotic use and prescription opioid abuse have been well documented. The aim of this study was to assess the prescribing decisions of general dentists and endodontists in British Columbia regarding analgesics and antibiotics in clinical scenarios that involve endodontic disease. An additional aim was to determine whether gender, clinical experience, or the practice location of the clinician impacted their decision-making. A four-page survey was developed and distributed to half of the general dentists in Vancouver, British Columbia (n=284) and all of the endodontists in British Columbia (n=51). The survey began with some basic demographical questions, continued with seven different clinical scenarios, and concluded with a table that listed a number of different endodontic diagnoses. The participants were asked questions regarding their decisions to recommend or prescribe analgesics or antibiotics. The response rate to the survey was 49.2%. 72.0% of endodontists responded, as compared to 44.8% of general dentists. A substantial proportion of clinicians prescribed opioid analgesics and antibiotics in the various clinical scenarios. The prescription of opioid analgesics ranged from 3.6% - 46.8% over the various scenarios. The prescription of antibiotics ranged from 4.8% - 88.4%. General dentists reported prescribing opioid analgesics and antibiotics more often than endodontists. However, the respondents to our survey prescribed antibiotics less frequently than those of a 1996 survey conducted in the USA. Gender, clinical experience, and practice location did not seem to impact the decision to prescribe opioid analgesics or antibiotics.

description: Distributed training of Deep Learning models has been critical to many recent successes in the field. Current standard methods primarily rely on synchronous centralized algorithms which induce major communication bottlenecks and synchronization locks at scale. Decentralized asynchronous algorithms are emerging as a potential alternative but their practical applicability still lags. In order to mitigate the increase in communication cost that naturally comes with scaling the number of workers, we introduce a principled asynchronous, randomized, gossip-based optimization algorithm which works thanks to a continuous local momentum named $\textbf{A}^2\textbf{CiD}^2$. Our method allows each worker to continuously process mini-batches without stopping, and run a peer-to-peer averaging routine in parallel, reducing idle time. In addition to inducing a significant communication acceleration at no cost other than adding a local momentum variable, minimal adaptation is required to incorporate $\textbf{A}^2\textbf{CiD}^2$ to standard asynchronous approaches. Our theoretical analysis proves accelerated rates compared to previous asynchronous decentralized baselines and we empirically show that using our $\textbf{A}^2\textbf{CiD}^2$ momentum significantly decrease communication costs in poorly connected networks. In particular, we show consistent improvement on the ImageNet dataset using up to 64 asynchronous workers (A100 GPUs) and various communication network topologies.
Corrosion behavior of Co28Cr6Mo implant in the presence of bovine serum albumin and hyaluronic acid
Creators: name: Hirzallah, Rana Rasim W
Publisher: name: University of British Columbia
Year: 2014

description: CoCrMo is one of the most widely used materials for prostheses. CoCrMo has high wear resistance, excellent corrosion resistance, and good biocompatibility. High corrosion resistance is ascribed to the formation of an oxide layer. However, the oxide layer does not remain intact in the corrosive body environment that contains oxygen, chloride, proteins, and carbohydrates. The presence of organic and inorganic species changes the oxide layer of CoCrMo to facilitate corrosion. Corrosion is one of the main issues that leads to revision surgery. CoCrMo has been used extensively in synovial joints replacements such as hip, knee, and shoulder. They are in contact with synovial fluid (SF) which mainly contains albumin and hyaluronic acid (HA). The concentrations of HA changes with age, sex, and diseases. The objective of this study is to investigate the effect of the main constituents of SF which are bovine serum albumin (BSA) and HA, on the corrosion performance of CoCrMo. In addition, this study also investigates the effect of changing HA concentrations on the corrosion behavior of CoCrMo. Increasing HA concentrations has reduced the pain for people with osteoarthritis. It may also have an effect on reducing the corrosion rate. To study the corrosion behavior of CoCrMo, different electrochemical techniques has been used to understand the formation and breakdown of the oxide layer, and calculate the corrosion rate by measuring the corrosion resistances and corrosion current densities. The results of electrochemical impedance spectroscopy (EIS) show that 4 gL-¹ of hyaluronic acid (HA) with bovine serum albumin (BSA) exhibited the highest corrosion resistance and the lowest corrosion rate of CoCrMo compared to only phosphate buffer saline (PBS), BSA, and PBS with different HA concentration.

description: Many types of anthocyanins are present in Vitis amurensis Rupr of ‘Beibinghong’, which is grown in North-east China and has high antioxidant activity. However, the anthocyanin with the highest content in V. amurensis Rupr has not yet been identified. In this study, pulsed electric field extraction and semi-preparative liquid phase separation were used to isolate the anthocyanin monomer from ‘Beibinghong’. UV–vis spectroscopy, FTIR spectroscopy, mass spectra and nuclear magnetic resonance were used to identify the anthocyanin monomer. The antioxidant activities of the anthocyanin monomer were also analysed. Malvidin-3,5-O-diglucoside was identified as the main anthocyanin in V. amurensis Rupr, which could be used as a raw material for its extraction. Furthermore, malvidin-3,5-O-diglucoside can be potentially used as a functional food, and a novel therapeutic and preventive agent for oxidative stress-related diseases. This study provides technical information for the future purification and structural identification of anthocyanins.

By placing a small gold nanoparticle on the end of the STM tip, a charge sensor is created. By raster scanning the tip over the surface and using Coulomb blockade spectroscopy, we map the local charge on the graphene. We observe a series of electron and hole doped puddles with a characteristic length scale of about 20 nm. Theoretical calculations for the correlation length of the puddles based on the number of impurities are in agreement with our measurements.

description: Interplanetary solar radio type III bursts provide the means for remotely studying and tracking energetic electrons propagating in the interplanetary medium. Due to the lack of direct radio source imaging, several methods have been developed to determine the source positions from space-based observations. Moreover, none of the methods consider the propagation effects of anisotropic radio-wave scattering, which would strongly distort the trajectory of radio waves, delay their arrival times, and affect their apparent characteristics. We investigate the source positions and directivity of an interplanetary type III burst simultaneously observed by Parker Solar Probe, Solar Orbiter, STEREO, and Wind and compare the results of applying the intensity fit and timing methods with ray-tracing simulations of radio-wave propagation with anisotropic density fluctuations. The simulation calculates the trajectories of the rays, their time profiles at different viewing sites, and the apparent characteristics for various density fluctuation parameters. The results indicate that the observed source positions are displaced away from the locations where emission is produced, and their deduced radial distances are larger than expected from density models. This suggests that the apparent position is affected by anisotropic radio-wave scattering, which leads to an apparent position at a larger heliocentric distance from the Sun. The methods to determine the source positions may underestimate the apparent positions if they do not consider the path of radio-wave propagation and incomplete scattering at a viewing site close to the intrinsic source position.

description: Point-of-Interest (POI ) recommendation systems have gained popularity for their unique ability to suggest geographical destinations with the incorporation of contextual information such as time, location, and user-item interaction. Existing recommendation frameworks lack the contextual fusion required for POI systems. This paper presents CAPRI, a novel POI recommendation framework that effectively integrates context-aware models, such as GeoSoCa, LORE, and USG, and introduces a novel strategy for the efficient merging of contextual information. CAPRI integrates an evaluation module that expands the evaluation scope beyond accuracy to include novelty, personalization, diversity, and fairness. With an aim to establish a new industry standard for reproducible results in the realm of POI recommendation systems, we have made CAPRI openly accessible on GitHub, facilitating easy access and contribution to the continued development and refinement of this innovative framework.

description: We present ultradeep radio observations with the Expanded Very Large Array of 4U 1957+11, a Galactic black hole candidate X-ray binary known to exist in a persistent soft X-ray state. We derive a stringent upper limit of 11.4 micro-Jy beam^-1 (3 sigma) at 5-7 GHz, which provides the most rigorous upper limit to date on the presence of jets in a soft state black hole X-ray binary. X-ray, UV and optical fluxes obtained within a few weeks of the radio data can be explained by thermal emission from the disk. At this X-ray luminosity, a hard state black hole X-ray binary that follows the established empirical radio--X-ray correlation would be at least 330-810 times brighter at radio frequencies, depending on the distance to 4U 1957+11. This jet quenching of > 2.5 orders of magnitude is greater than some models predict, and implies the jets are prevented from being launched altogether in the soft state. 4U 1957+11 is also more than one order of magnitude fainter than the faintest of the 'radio-quiet' population of hard state black holes. In addition, we show that on average, soft state stellar-mass BHs probably have fainter jets than most active galactic nuclei in a state equivalent to the soft state. These results have implications for the conditions required for powerful, relativistic jets to form, and provide a new empirical constraint for time- and accretion mode-dependent jet models, furthering our understanding of jet production and accretion onto BHs.

description: We study signatures of macroscopic dark matter (DM) in current and future gravitational wave (GW) experiments. Transiting DM with a mass of $\sim10^5-10^{15}$ kg that saturates the local DM density can be potentially detectable by GW detectors, depending on the baseline of the detector and the strength of the force mediating the interaction. In the context of laser interferometers, we derive the gauge invariant observable due to a transiting DM, including the Shapiro effect (gravitational time delay accumulated during the photon propagation), and adequately account for the finite photon travel time within an interferometer arm. In particular, we find that the Shapiro effect can be dominant for short-baseline interferometers such as Holometer and GQuEST. We also find that proposed experiments such as Cosmic Explorer and Einstein Telescope can constrain a fifth force between DM and baryons, at the level of strength $\sim 10^3$ times stronger than gravity for, e.g., kg mass DM with a fifth-force range of $10^6$ m.

Both dopants exhibit a strong chemical driving force for the formation of M_Ti-V_O (M = Cu, Fe) defect associates. The most stable configurations corresponds to a local dipole aligned along the tetragonal axis parallel to the spontaneous polarization. Local spin moments are obtained and the calculated spin densities are discussed. The calculations provide a simple and consistent explanation for the experimental findings. The results are discussed in the context of models for degradation of ferroelectric materials.

description: Semi-supervised learning has demonstrated great potential in medical image segmentation by utilizing knowledge from unlabeled data. However, most existing approaches do not explicitly capture high-level semantic relations between distant regions, which limits their performance. In this paper, we focus on representation learning for semi-supervised learning, by developing a novel Multi-Scale Cross Supervised Contrastive Learning (MCSC) framework, to segment structures in medical images. We jointly train CNN and Transformer models, regularising their features to be semantically consistent across different scales. Our approach contrasts multi-scale features based on ground-truth and cross-predicted labels, in order to extract robust feature representations that reflect intra- and inter-slice relationships across the whole dataset. To tackle class imbalance, we take into account the prevalence of each class to guide contrastive learning and ensure that features adequately capture infrequent classes. Extensive experiments on two multi-structure medical segmentation datasets demonstrate the effectiveness of MCSC. It not only outperforms state-of-the-art semi-supervised methods by more than 3.0% in Dice, but also greatly reduces the performance gap with fully supervised methods.

description: Three isostructural cyano-bridged heptanuclear complexes, [{CuII(saldmen)(H2O)}6{MIII(CN)6}](ClO4)3$\cdotp$8H2O (M = FeIII 2; CoIII, 3; CrIII 4), have been obtained by reacting the binuclear copper(II) complex, [Cu2(saldmen)2(mu-H2O)(H2O)2](ClO4)2$\cdotp$2H2O 1, with K3[Co(CN)6], K4[Fe(CN)6], and, respectively, K3[Cr(CN)6] (Hsaldmen is the Schiff base resulted from the condensation of salicylaldehyde with N,N-dimethylethylenediamine). A unique octameric water cluster, with bicyclo[2,2,2]octane-like structure, is sandwiched between the heptanuclear cations in 2, 3 and 4. The cryomagnetic investigations of compounds 2 and 4 reveal ferromagnetic couplings of the central FeIII or CrIII ions with the CuII ions (JCuFe = +0.87 cm-1, JCuCr = +30.4 cm-1). The intramolecular Cu-Cu exchange interaction in 3, across the diamagnetic cobalt(III) ion, is -0.3 cm-1. The solid-state1H-NMR spectra of compounds 2 and 3 have been investigated.

description: In the domain of unsupervised image-to-image transformation using generative transformative models, CycleGAN has become the architecture of choice. One of the primary downsides of this architecture is its relatively slow rate of convergence. In this work, we use discriminator-driven explainability to speed up the convergence rate of the generative model by using saliency maps from the discriminator that mask the gradients of the generator during backpropagation, based on the work of Nagisetty et al., and also introducing the saliency map on input, added onto a Gaussian noise mask, by using an interpretable latent variable based on Wang M.'s Mask CycleGAN. This allows for an explainability fusion in both directions, and utilizing the noise-added saliency map on input as evidence-based counterfactual filtering. This new architecture has much higher rate of convergence than a baseline CycleGAN architecture while preserving the image quality.

description: Strong interaction between the light field and an atom is often achieved with cavities. Recent experiments have used a different configuration: a propagating light field is strongly focused using a system of lenses, the atom being supposed to sit at the focal position. In reality, this last condition holds only up to some approximation; in particular, at any finite temperature, the atom position fluctuates. We present a formalism that describes the focalized field and the atom sitting at an arbitrary position. As a first application, we show that thermal fluctuations do account for the extinction data reported in M. K. Tey et al., Nature Physics 4, 924 (2008).

description: The dilatation operator of planar N=4 super Yang-Mills in the pure scalar SO(6) sector is derived at the two-loop order. Representation theory allows for eight free coefficients in an ansatz for the corresponding spin-chain hamiltonian acting on three adjacent scalar states. While four out of these follow from the known SU(2|3) sector two-loop dilatation operator, the remaining four coefficients are derived by diagrammatic techniques and a match to the known dimension of a length three primary operator. Finally, comments upon the use of this result for the evaluation of three-point structure functions of scalar operators at the one-loop order are given.

description: We report the discovery of an eclipsing cataclysmic variable with eclipse depths > 5.7 mag, orbital period 94.657 min, and peak brightness V~18 at J2000 position 17h 25m 54s.8, -64d 38' 39". Detected by visual inspection of images from Yale University's QUEST camera on the ESO 1.0-m Schmidt telescope at La Silla, we obtained light curves in B, V, R, I, z and J with the SMARTS 1.3-m and 1.0-m telescopes at Cerro Tololo and spectra from 3500 to 9000 Angstrom with the SOAR 4.3-m telescope at Cerro Pachon. The optical light curves show a deep, 5-min eclipse immediately followed by a shallow 38-min eclipse and then sinusoidal variation. No eclipses appear in J. During the deep eclipse we measure V-J > 7.1, corresponding to a spectral type M8 or later secondary, consistent with the dynamical constraints. The estimated distance is 150 psec. The spectra show strong Hydrogen emission lines, Doppler broadened by 600 - 1300 km/s, oscillating with radial velocity that peaks at mid deep eclipse with semi-amplitude 500 +/- 22 km/s. We suggest that LSQ172554.8-643839 is a polar with a low-mass secondary viewed at high inclination. No known radio or x-ray source coincides with the new object's location.

Simulating human tumour heterogeneity using cancer cell line mixtures
Creators: name: Billings, Raewyn Lorraine
Publisher: name: University of British Columbia

description: Tumours comprise (epi)genetically and phenotypically diverse cellular subpopulations evolving over space and time. This heterogeneity can be observed as differences in morphology or immunohistology of tumour sections, gene expression levels, genomic sequence and structure, proliferative potential, or metastatic ability. In order to unravel how this heterogeneity persists, one may study the clonal structure and evolution of tumours. Understanding intra-tumor heterogeneity, or the differences amongst cells in a single tumour, is of particular importance to facilitate treatment combinations that effectively target all clinically relevant subclones. This clonality-informed approach requires identification and monitoring of clonal cell populations within a tumour. In this study I simulated tumour heterogeneity using cancer cells lines in idealised mixtures. Deep allelic measurements using next generation DNA amplicon sequencing were integrated in a computational modelling program (PyClone), to retrieve cellular prevalence’s and clonal structure within these cell line mixtures. This approach to modeling heterogeneity employed both diploid and aneuploid cell lines with genomic analysis focused on heterozygous alleles and changes in the prevalence of theses alleles when cell lines were mixed in different proportions. As a result I first identified that using NGS and PyClone modeling enables elucidation of population clonal structure as predicted from idealised mixtures of diploid cell lines. However, the aneuploidy cell line mixtures demonstrated a requirement for copy number information to be included as a prior input to clonality modeling in order to avoid misleading interpretations of cellular prevalence and clonal structure. Defining and monitoring clonal heterogeneity in patient tumours is of importance to track functionally relevant subpopulations of tumour cells, enabling oncologists to administer cocktails of therapeutic agents targeting relevant clones irrespective of their numerical abundance. This clonality-informed iii treatment approach is a promising development to tackle the growing challenge of therapy resistant subclones and thus limit cancer recurrence.

description: A 0+1-dimensional candidate theory for the CFT$_1$ dual to AdS$_2$ is discussed. The quantum mechanical system does not have a ground state that is invariant under the three generators of the conformal group. Nevertheless, we show that there are operators in the theory that are not primary, but whose "non-primary character" conspires with the "non-invariance of the vacuum" to give precisely the correlation functions in a conformally invariant theory.

description: The understanding of disordered quantum systems is still far from being complete, despite many decades of research on a variety of physical systems. In this review we discuss how Bose-Einstein condensates of ultracold atoms in disordered potentials have opened a new window for studying fundamental phenomena related to disorder. In particular, we point our attention to recent experimental studies on Anderson localization and on the interplay of disorder and weak interactions. These realize a very promising starting point for a deeper understanding of the complex behaviour of interacting, disordered systems.

Kempnyia neotropica – Froehlich, 2010:181. Remarks. Bispo & Froehlich (2004) noted, that “as presently understood, the species is widely distributed, its area being similar to the distribution of the genus. A careful analysis of specimens from different areas is needed to evaluate if they really belong to a single species”. Zwick (1972) examined specimens from four States, Espírito Santo, Rio de Janeiro, Santa Catarina and Rio Grande do Sul. Besides Santa Catarina, I have examined material from Minas Gerais (Serra do Cipó) São Paulo (Municipalities of Campos do Jordão, Cubatão, Iporanga, Jundiaí, Pindamonhangaba, Salesópolis and Santo André) and Goi á s (Pirenópolis). These specimens are similar in the dark body color, the structure of the male genitalia, the elliptical contour of the female subgenital plate covering part of sternum 10 and with a small apical indentation (Fig. 1). Local populations differ in body length and in color, sometimes a lighter band may be present on the pronotum and the femora may be more or less bicolored. The species concept presented by Bispo and Froehlich (2004) is confirmed. A new figure of the female subgenital plate and sternum 9 is presented in Fig. 1 and of the egg (Fig. 2) based on a female from the Boracéia Biological Station (Salesópolis Municipality).
