description: Obtaining atomistic resolution of drug unbinding from a protein is a much sought-after experimental and computational challenge. We report the unbinding dynamics of the anticancer drug dasatinib from c-Src kinase in full atomistic resolution using enhanced sampling molecular dynamics simulations. We obtain multiple unbinding trajectories and determine a residence time in agreement with experiments. We observe coupled protein-water movement through multiple metastable intermediates. The water molecules form a hydrogen bond bridge, elongating a specific, evolutionarily preserved salt bridge and enabling conformation changes essential to ligand unbinding. This water insertion in the salt bridge acts as a molecular switch that controls unbinding. Our findings provide a mechanistic rationale for why it might be difficult to engineer drugs targeting certain specific c-Src kinase conformations to have longer residence times.

description: Random spatial models are attractive for modeling heterogeneous cellular networks (HCNs) due to their realism, tractability, and scalability. A major limitation of such models to date in the context of HCNs is the neglect of network traffic and load: all base stations (BSs) have typically been assumed to always be transmitting. Small cells in particular will have a lighter load than macrocells, and so their contribution to the network interference may be significantly overstated in a fully loaded model. This paper incorporates a flexible notion of BS load by introducing a new idea of conditionally thinning the interference field. For a K-tier HCN where BSs across tiers differ in terms of transmit power, supported data rate, deployment density, and now load, we derive the coverage probability for a typical mobile, which connects to the strongest BS signal. Conditioned on this connection, the interfering BSs of the $i^{th}$ tier are assumed to transmit independently with probability $p_i$, which models the load. Assuming - reasonably - that smaller cells are more lightly loaded than macrocells, the analysis shows that adding such access points to the network always increases the coverage probability. We also observe that fully loaded models are quite pessimistic in terms of coverage.

Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow

description: We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbulent flow. The flow field is analyzed by tracking the temporal evolution of small fluorescent tracer particles. The inertial particles consist of a super-absorbent polymer that renders them index and density matched with water and thus invisible. The particles are marked by inserting at various locations tracer particles into the polymer. Translation and rotation, as well as the flow field around the particle are recovered dynamically from the analysis of the marker and tracer particle trajectories. We apply this technique to study the dynamics of inertial particles much larger in size (Rp/η \approx 100) than the Kolmogorov length scale η in a von Kármán swirling water flow (Rλ \approx 400). We show, using the mixed (particle/fluid) Eulerian second order velocity structure function, that the interaction zone between the particle and the flow develops in a spherical shell of width 2Rp around the particle of radius Rp. This we interpret as an indication of a wake induced by the particle. This measurement technique has many additional advantages that will make it useful to address other problems such as particle collisions, dynamics of non-spherical solid objects, or even of wet granular matter.

description: The rise time of a Galactic supernova (SN) bar-nue lightcurve, observable at a high-statistics experiment such as the IceCube Cherenkov detector, can provide a diagnostic tool for the neutrino mass hierarchy at "large" 1-3 leptonic mixing angle theta_13. Thanks to the combination of matter suppression of collective effects at early postbounce times on one hand and the presence of the ordinary Mikheyev-Smirnov-Wolfenstein effect in the outer layers of the SN on the other hand, a sufficiently fast rise time on O(100) ms scale is indicative of an inverted mass hierarchy. We investigate results from an extensive set of stellar core-collapse simulations, providing a first exploration of the astrophysical robustness of these features. We find that for all the models analyzed (sharing the same weak interaction microphysics) the rise times for the same hierarchy are similar not only qualitatively, but also quantitatively, with the signals for the two classes of hierarchies significantly separated. We show via Monte Carlo simulations that the two cases should be distinguishable at IceCube for SNe at a typical Galactic distance 99% of the times. Finally, a preliminary survey seems to show that the faster rise time for inverted hierarchy as compared to normal hierarchy is a qualitatively robust feature predicted by several simulation groups. Since the viability of this signature ultimately depends on the quantitative assessment of theoretical/numerical uncertainties, our results motivate an extensive campaign of comparison of different code predictions at early accretion times with implementation of microphysics of comparable sophistication, including effects such like nucleon recoils in weak interactions.

description: By solving the Faddeev equations we calculate the mass of the strange baryons in the framework of a relativistic constituent quark model. The Goldstone-boson-exchange quark-quark interaction is derived from $SU(3)_F$ symmetry, which is explicitly broken as the strange quark is much heavier. This broken symmetry can nicely be accounted for in the Faddeev framework.

description: This Article explains and explores new Securities Exchange Commission rules authorizing optional swing pricing for mutual funds. Swing pricing is an anti-dilution tool intended to protect sedentary investors who enter, and stay, in a fund. Workers setting aside money for retirement are often sedentary investors. Mutual funds are the mainstay vehicle for retirement investors, yet as sedentary shareholders they can experience significant asset dilution over their savings lifetime. Swing pricing—a mutual fund pricing mechanism that allocates transaction costs to the triggering shareholders—could save sedentary shareholders, collectively, billions of dollars. The mutual fund industry’s operational complexities and competing regulatory obligations may prevent funds from immediately utilizing swing pricing once it becomes effective in November 2018. The biggest obstacle is a time conflict reminiscent of the chicken and egg problem. Under current industry operations, mutual funds will not receive the trading information necessary to adjust the daily price of the fund (swing the price) until after funds have to finalize the price adjustment. Blockchain technology—offering secure, automated, and verified ledgers—may present an operational path forward for the industry. The SEC’s swing pricing approach leaves unanswered how funds will overcome these, and other, hurdles. This Article explores the components of swing pricing, as well as the objections to and perceived benefits of swing pricing, and concludes with two unique perspectives on the SEC rules: one academic and one professional. This Article maintains that mutual funds should take on the challenge of implementing swing pricing, and that market incentives will pave the way.

description: We consider a transport setup containing a double-dot connected by a continuum. Via an exact solution of the time-dependent Schrödinger equation, we demonstrate a highly non-Markovian quantum-coherence-mediated transport through this dot-continuum-dot (DCD) system, which is in contrast with the common premise since in typical case a quantum particle does not reenter the system of interest once it irreversibly decayed into a continuum (such as the spontaneous emission of a photon). We also find that this DCD system supports an unusual steady state with unequal source and drain currents, owing to electrons irreversibly entering the continuum and floating there.

description: At most mid-ocean ridges, a wide region of decompression melting must be reconciled with a narrow neovolcanic zone and the establishment of full oceanic crustal thickness close to the rift axis. Two competing paradigms have been proposed to explain melt focusing: narrow mantle upwelling due to dynamic effects related to in situ melt or wide mantle upwelling with lateral melt transport in inclined channels. Measurements of seismic attenuation provide a tool for identifying and characterizing the presence of melt and thermal heterogeneity in the upper mantle. We use a unique data set of teleseismic body waves recorded on the Cascadia Initiative’s Amphibious Array to simultaneously measure seismic attenuation and velocity across an entire oceanic microplate. We observe maximal differential attenuation and the largest delays (Embedded Image s and δTS ~ 2 s) in a narrow zone <50 km from the Juan de Fuca and Gorda ridge axes, with values that are not consistent with laboratory estimates of temperature or water effects. The implied seismic quality factor (Qs ≤ 25) is among the lowest observed worldwide. Models harnessing experimentally derived anelastic scaling relationships require a 150-km-deep subridge region containing up to 2% in situ melt. The low viscosity and low density associated with this deep, narrow melt column provide the conditions for dynamic mantle upwelling, explaining a suite of geophysical observations at ridges, including electrical conductivity and shear velocity anomalies.
Exploring and constraining new physics in the dark sector

Publisher: name: University of British Columbia

description: The standard cosmological model that has emerged in the last decades describes an acceleratingly expanding universe where the familiar baryonic matter accounts for a very small fraction of the overall energy budget. The vast majority of the energy content of the Universe appears to belong to an elusive dark sector made up of dark matter and dark energy. In this thesis, we explore the cosmological consequences of new physics that could govern this unknown dark sector. We first consider a model where dark matter can annihilate to Standard-Model particles through a Breit-Wigner resonance. We show in this case that the energy released by dark matter annihilating in the first proto-halos is likely substantial. We determine that the bounds on the allowed energy injection into the primordial gas and the energy density of the diffuse gamma-ray background strongly constrain the magnitude of the resonantly-enhanced annihilation cross-section. We then perform a thorough analysis of a dark sector made of atom-like bound states. This so-called Atomic Dark-Matter model predicts novel dark-matter properties on small scales but retains the success of cold dark matter on cosmological scales. We revisit the atomic physics necessary to capture the thermal history of the dark atoms and discuss the required improvements over the hydrogen calculation. To solve the perturbation equations, we develop a second-order tight-coupling approximation and further discuss its implications for the baryon-photon case. We compute the matter power spectrum in this model and show that it displays strong dark-matter acoustic oscillations and a cutoff on small scales. Interestingly, we also identify key cosmic microwave background signatures that distinguish the atomic dark-matter scenario from other dark-matter theories. We determine that astrophysical constraints on this model generally favour dark atoms that are both more massive and have higher binding energies than standard atomic hydrogen. We finally consider how oscillations in the bispectrum of primordial fluctuations affects the clustering of dark-matter halos. We discover that features in the inflaton potential such as oscillations and bumps become imprinted in the mass dependence of the non-Gaussian halo bias. This finding opens the possibility of characterizing the inflationary potential with large-scale-structure surveys.

We also provide results for forces with singularity up to $α< d-1$ but with large enough cut-off. This last result thus almost includes the most interesting case of Coulombian or gravitational interaction, but it is also interesting when the strength of the singularity $α$ is larger but close to one, in which case it allows for very small cut-off.

We estimate the coefficient of proportionality at critical temperature and find its denpendence on external magnetic field. By exploring phase diagrams of critical temperature and magnetic field for various condensates, we conclude that a Meissner-like effect is a general feature in Holographic superconductors. We also study the quantum phase transition at zero temperature and find that critical charge density increases linearly with the condensate dimension.

description: We describe the results achieved using the JAM distributed data mining system for the real world problem of fraud detection in financial information systems. For this domain we provide clear evidence that state-of-the-art commercial fraud detection systems can be substantially improved in stopping losses due to fraud by combining multiple models of fraudulent transaction shared among banks. We demonstrate that the traditional statistical metrics used to train and evaluate the performance of learning systems (i.e. statistical accuracy or ROC analysis) are misleading and perhaps inappropriate for this application. Cost-based metrics are more relevant in certain domains, and defining such metrics poses significant and interesting research questions both in evaluating systems and alternative models, and in formalizing the problems to which one may wish to apply data mining technologies. This paper also demonstrates how the techniques developed for fraud detection can be generalized and applied to the important area of intrusion detection in networked information systems. We report the outcome of recent evaluations of our system applied to tcpdump network intrusion data specifically with respect to statistical accuracy. This work involved building additional components of JAM that we have come to call, MADAM ID (Mining Audit Data for Automated Models for Intrusion Detection). However, taking the next step to define cost-based models for intrusion detection poses interesting new research questions. We describe our initial ideas about how to evaluate intrusion detection systems using cost models learned during our work on fraud detection.

description: Background: Nuclear effects can have a significant impact on neutrino-nucleus interactions. In particular, data from neutrino experiments with broad energy distributions require complex theoretical models that are able to take all the relevant channels into account as well as incorporate nuclear effects in both initial and final-state interactions. Purpose: We investigate neutrino and antineutrino scattering on iron and carbon in the energy range from 1 to 30 GeV, which is relevant to current and coming experiments (MINOS, NOvA, and Minerva). Method: The Giessen Boltzmann--Uehling--Uhlenbeck (GiBUU) model, which implements all reaction channels relevant for neutrino energies under consideration, is used for an investigation of neutrino-nucleus reactions. Results: Our calculations are compared with the recent NOMAD and MINOS data for the integrated inclusive cross sections. Predictions are made for the differential cross sections for semiinclusive final states (pions, kaons, and nucleons) for the MINOS and NOvA beams. Conclusions: Nuclear effects in the initial-state interactions may slightly change the inclusive nuclear cross section as compared to the free nucleon ones. Final-state interactions noticeably change the spectra of the outgoing hadrons. In the Minerva and NOvA experiments these effects should be visible in the kinetic energy distributions of the final pions, kaons, and nucleons. Secondary interactions play an important role for strangeness production.

Creators: name: Boey, Augustin Ying Yip
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: This thesis examines the relationship between city-regional networks and the geography of innovation in the UK. Social and economic networks are vital to the economic vitality and creative dynamism of cities. They are the social infrastructure connecting individuals, ideas, and places--bringing them together in novel and more productive ways—and generating opportunities to advance the technological frontier. The complex patterns linking individuals and communities also affect performance by unevenly structuring access to economic opportunities. Network diversity at the city-regional scale likewise contributes to divergent local development by constraining prospects for cluster growth and technological upgrading. Social networks are broadly acknowledged as the locus of high-technology innovation. Unfortunately, insight into the causes and mechanisms underpinning the social gains of city-regional networks remains thin: networks with open structure are pervasively thought to underpin high-tech cluster success, yet this critical assumption has remained unexamined; the roles and contributions of networked individuals on regional innovation has yet to be systematically studied; and the question of how new high-tech industries at the cutting-edge emerge vis-à-vis networks in related industries has not received sustained examination. Moreover, the empirical literature has focused on a relatively limited set of prominent agglomerations—partly due to a lack of appropriate relational data to construct city-regional networks—leaving open questions of generalizability beyond these settings. This thesis makes five substantive contributions towards remedying these research gaps. First, it integrates emerging large-scale data sources and develops novel datasets to build and analyse UK city-regional networks. Second, it examines the impacts of highly connected individuals – ‘dealmakers’ – on local performance, finding a causal effect of regional dealmakers on innovativeness productivity. Third, it evaluates their asymmetric roles relative to other actors in importing externally sourced knowledge 4 into city-regions. Fourth, it systematically revisits foundational claims about the importance of open networks in sustaining highly innovative places. It develops a new measure of network openness by synthesizing complex multidisciplinary debates. It finds a causal effect of open networks on subsequent high-tech growth – the findings also suggest limits to open network effectiveness. Fifth, it provides a first empirical examination of emerging frontier industries focusing on fintech, exploring how much of its development has been shaped by antecedent capabilities and the social organization of regional finance and digital economy industries. The findings suggest that open network structures in the disrupting antecedent industry drive new industry growth.

description: Although a growing body of literature identifies the within-firm redistribution effects of trade, research on the adjustment processes in within-firm labor markets is scarce. This study analyzes the within-firm adjustment of working hours and wages by considering workers’ educational background and gender in response to a change in offshoring. Matched worker–firm panel data in the Japanese manufacturing sector covering 1998 to 2013 are being used. The analysis leads to the following observations: First, offshoring does not significantly change monthly and annual incomes. Second, offshoring decreases working hours—that is, imported inputs are close substitutes for labor inputs. More than three-quarters of the decrease in scheduled working hours can be attributed to a decrease in working days. Third, hourly wages increase in all worker groups examined. Though the impacts of offshoring on hourly wages and incomes are contradictory, both share the same feature: offshoring expands neither skill premium nor gender gap.

description: Lead halide perovskites have been demonstrated as high performance materials in solar cells and light-emitting devices. These materials are characterized by coherent band transport expected from crystalline semiconductors, but dielectric responses and phonon dynamics typical of liquids. This “crystal-liquid” duality implies that lead halide perovskites belong to phonon glass electron crystals, a class of materials believed to make the most efficient thermoelectrics. We show that the crystal-liquid duality and the resulting dielectric response are responsible for large polaron formation and screening of charge carriers, leading to defect tolerance, moderate charge carrier mobility, and radiative recombination properties. Large polaron formation, along with the phonon glass character, may also explain the marked reduction in hot carrier cooling rates in these materials.

description: No abstracts are to be cited without prior reference to the author.Tag-recapture studies are an important tool in pelagic fisheries for estimating fishing mortality (harvest) rates, natural mortality rates and abundance. For studies of wideranging pelagic species, such as southern bluefin tuna (SBT), spatial models for analysing the data are often necessary to get unbiased parameter estimates; this is especially true when tags are released in a limited range of the overall distribution. Here we present a discrete-space, discrete-time model that was developed for SBT conventional tagging data. We show how information from archival tags can be used to improve the model in terms of structure and parameter estimation

description: In the context of nonparametric Bayesian estimation a Markov chain Monte Carlo algorithm is devised and implemented to sample from the posterior distribution of the drift function of a continuously or discretely observed one-dimensional diffusion. The drift is modeled by a scaled linear combination of basis functions with a Gaussian prior on the coefficients. The scaling parameter is equipped with a partially conjugate prior. The number of basis function in the drift is equipped with a prior distribution as well. For continuous data, a reversible jump Markov chain algorithm enables the exploration of the posterior over models of varying dimension. Subsequently, it is explained how data-augmentation can be used to extend the algorithm to deal with diffusions observed discretely in time. Some examples illustrate that the method can give satisfactory results. In these examples a comparison is made with another existing method as well.

From remains to rituals : exploring the changing mortuary program at El Rayo, Nicaragua

description: El Rayo is an archaeological site in Pacific Nicaragua that spans two time periods the Bagaces (AD 300-800) and Sapoa (AD 800-1350). In addition to the domestic assemblage of the site, El Rayo also contains burials from both time periods. El Rayo is one of the most well documented archaeological sites in Nicaragua and the presence of both Bagaces and Sapoa material makes it a valuable archaeological site. In comparing the burial assemblage, the patterns which appear in the archaeological record are distinct in the different time periods. These patterns, including the change in the location of burials from within domestic areas to specific mortuary contexts, a transition from single to multiple burials, and the inclusion of burial goods with the burials that appear to represent significant changes in the rituals associated with the burial of the dead. By exploring the mortuary program at El Rayo I argue that the changes represent the negotiation of a single community through changing cultural circumstances that mark and in some ways define the transition from the Bagaces Period to the Sapoa Period. The mortuary program shows continuity which supports the notion of cultural interactions without the complete replacement of one group by another. I focus on the burial area and the nature of the remains to interpret a changing mortuary program rather than focusing on the mortuary goods recovered with specific individuals. Based on Arthur Saxe’s Hypothesis 8 that argues for the connection between the use and maintenance of formal cemeteries and control of critical resources (1970:119). I suggest that the changing mortuary program is the result of increased population pressures and the desire to create public markers of identity and ownership of local resources.

Mining Audit Data to Build Intrusion Detection Models

description: In this paper we discuss a data mining framework for constructing intrusion detection models. The key ideas are to mine system audit data for consistent and useful patterns of program and user behavior, and use the set of relevant system features presented in the patterns to compute (inductively learned) classifiers that can recognize anomalies and known intrusions. Our past experiments showed that classifiers can be used to detect intrusions, provided that sufficient audit data is available for training and the right set of system features are selected. We propose to use the association rules and frequent episodes computed from audit data as the basis for guiding the audit data gathering and feature selection processes. We modify these two basic algorithms to use axis attribute(s) as a form of item constraints to compute only the relevant ("useful") patterns, and an iterative level-wise approximate mining procedure to uncover the low frequency (but important) patterns. We report our experiments in using these algorithms on real-world audit data.

description: Femtosecond resolution electron scattering techniques are applied to resolve the first atomic-scale steps following absorption of a photon in the prototypical hybrid perovskite methylammonium lead iodide. Following above-gap photoexcitation, we directly resolve the transfer of energy from hot carriers to the lattice by recording changes in the mean square atomic displacements on 10-ps time scales. Measurements of the time-dependent pair distribution function show an unexpected broadening of the iodine-iodine correlation function while preserving the Pb–I distance. This indicates the formation of a rotationally disordered halide octahedral structure developing on picosecond time scales. This work shows the important role of light-induced structural deformations within the inorganic sublattice in elucidating the unique optoelectronic functionality exhibited by hybrid perovskites and provides new understanding of hot carrier—lattice interactions, which fundamentally determine solar cell efficiencies.

description: We report stellar parameters for late-K and M-type planet-candidate host stars announced by the Kepler Mission. We obtained medium-resolution, K-band spectra of 84 cool (Teff < 4400 K) Kepler Objects of Interest (KOIs) from Borucki et al. We identified one object as a giant (KOI 977); for the remaining dwarfs, we measured effective temperatures (Teff) and metallicities ([M/H]) using the K-band spectral indices of Rojas-Ayala et al. We determine the masses and radii of the cool KOIs by interpolation onto the Dartmouth evolutionary isochrones. The resultant stellar radii are significantly less than the values reported in the Kepler Input Catalogue and, by construction, correlate better with Teff. Applying the published KOI transit parameters to our stellar radius measurements, we report new physical radii for the planet candidates. Recalculating the equilibrium temperatures of the planet-candidates assuming Earth's albedo and re-radiation fraction, we find that 3 of the planet-candidates are terrestrial-sized with orbital semi-major axes that lie within the habitable zones of their host stars (KOI 463.01, KOI 812.03 and KOI 854.01). The stellar parameters presented in this letter serve as a resource for prioritization of future follow-up efforts to validate and characterize the cool KOI planet candidates.
description: Published in ApJ Letters. We now interpolate measured Teff and [M/H] onto Dartmouth isochrones (originally used Padova in v1), and include method verification on nearby stars (see new Figure 3). Machine readable table is available in the source code

description: Given a unitary evolution 𝑈 on a multipartite quantum system and an ensemble of initial states, how well can 𝑈 be simulated by local operations and classical communication (LOCC) on that ensemble? We answer this question by establishing a general, efficiently computable upper bound on the maximal LOCC simulation fidelity—what we call an “LOCC inequality.” We then apply our findings to the fundamental setting where 𝑈 implements a quantum Newtonian Hamiltonian over a gravitationally interacting system. Violation of our LOCC inequality can rule out the LOCCness of the underlying evolution, thereby establishing the nonclassicality of the gravitational dynamics, which can no longer be explained by a local classical field. As a prominent application of this scheme we study systems of quantum harmonic oscillators initialized in coherent states following a normal distribution and interacting via Newtonian gravity, and discuss a possible physical implementation with torsion pendula. One of our main technical contributions is the analytical calculation of the above LOCC inequality for this family of systems. As opposed to existing tests based on the detection of gravitationally mediated entanglement, our proposal works with coherent states alone, and thus it does not require the generation of largely delocalized states of motion nor the detection of entanglement, which is never created at any point in the process.
