description: We investigate the thermodynamic geometries of the most general static, spherically symmetric, topological black holes of the Hořava--Lifshitz gravity. In particular, we show that a Legendre invariant metric derived in the context of geometrothermodynamics for the equilibrium manifold reproduces correctly the phase transition structure of these black holes. Moreover, the limiting cases in which the mass, the entropy or the Hawking temperature vanish are also accompanied by curvature singularities which indicate the limit of applicability of the thermodynamics and the geometrothermodynamics of black holes. The Einstein limit and the case of a black hole with flat horizon are also investigated.

description: We elucidate the geometry of quantum adiabatic evolution. By minimizing the deviation from adiabaticity we find a Riemannian metric tensor underlying adiabatic evolution. Equipped with this tensor, we identify a unified geometric description of quantum adiabatic evolution and quantum phase transitions, which generalizes previous treatments to allow for degeneracy. The same structure is relevant for applications in quantum information processing, including adiabatic and holonomic quantum computing, where geodesics over the manifold of control parameters correspond to paths which minimize errors. We illustrate this geometric structure with examples, for which we explicitly find adiabatic geodesics. By solving the geodesic equations in the vicinity of a quantum critical point, we identify universal characteristics of optimal adiabatic passage through a quantum phase transition. In particular, we show that in the vicinity of a critical point describing a second order quantum phase transition, the geodesic exhibits power-law scaling with an exponent given by twice the inverse of the product of the spatial and scaling dimensions.

description: There are still many important unsolved problems in general relativity, two of which are the stability problem and the strong cosmic censorship conjecture. Both of these are ex- tremely difficult, but we can gain some insight by studying linear versions of them. These simplifications give rise to wave equations on curved spacetimes. We investigate the classical stability of supersymmetric, asymptotically flat microstate geometries with 5 non-compact dimensions. These geometries possess an evanescent ergo-surface, where there are stably trapped null geodesics that have zero energy relative to an observer at infinity. We give a heuristic argument as to why this may lead to a non-linear instability, which can be seen at the linear level by studying the wave equation. We calculate the quasinormal mode frequencies and find that, due to the stable trapping, the rate of decay is extremely slow. This suggests that stability is very unlikely at the non-linear level. The behaviour of geodesics is crucial for this, so we also investigate the geodesics in these microstate geometries in some detail. There has recently been evidence to suggest that Christodoulou’s formulation of the strong cosmic censorship conjecture is actually false for Reissner-Nordstron-de Sitter black holes sufficiently close to extremality. We investigate this problem for the more physical rotating Kerr-de Sitter black holes. We look at the linear problem, and find that solutions of the wave equation decay sufficiently slowly to suggest that strong cosmic censorship is respected. The two problems mentioned so far are both related to predictability in general relativ- ity. We investigate predictability more generally for subluminal and superluminal Lorentz- invariant scalar wave equations. We study the Born-Infeld scalar in two dimensions, which has both a superluminal and subluminal formulation. Contrary to previous expectation, we find that, at least in some sense, the subluminal equation behaves worse the superluminal equation. It is possible to have multiple different maximal globally hyperbolic developments arising from the same initial data for the subluminal equation, but the solution is unique in the superluminal case.

description: We present an extension of our GPGCD method, an iterative method for calculating approximate greatest common divisor (GCD) of univariate polynomials, to multiple polynomial inputs. For a given pair of polynomials and a degree, our algorithm finds a pair of polynomials which has a GCD of the given degree and whose coefficients are perturbed from those in the original inputs, making the perturbations as small as possible, along with the GCD. In our GPGCD method, the problem of approximate GCD is transferred to a constrained minimization problem, then solved with the so-called modified Newton method, which is a generalization of the gradient-projection method, by searching the solution iteratively. In this paper, we extend our method to accept more than two polynomials with the real coefficients as an input.

Automated design and implementation of Kalman observer for spindle torque estimation in CNC machining
Creators: name: Lu, Zhao Wei
Publisher: name: University of British Columbia
Year: 2020

description: Milling is a subtractive manufacturing technique, where the material is continuously removed from a workpiece until the desired part shape is obtained. Heavily used in the automotive and aerospace industries, Computer Numerical Control (CNC) milling machines occupy a large chunk in the manufacturing process. The current research focuses towards machining and machine tool monitoring systems that are more self-sufficient and self-adjusting to adapt the processes to machine tools. Cutting torque delivered by the machine tool spindle is one of the key sensory signals for machining process monitoring. This thesis presents a method that automatically reconstructs cutting torque from motor current commands generated by the servo controller of the machine tool. To estimate the cutting torque from commanded spindle current, the dynamics between torque to current relationship must be modeled and compensated. The thesis first presents an automated identification of spindle dynamics using data-driven system identification methods. The frequency response function (FRF) of the spindle dynamics is measured manually using CNC internal diagnostic tools. The identified FRF is then automatically converted to a state-space model using the Eigensystem Realization Algorithm (ERA). To reduce overfitting, an optimal threshold is applied to the ERA method to limit the identified system order. And to ensure the stability of the identified system, unstable eigenvalues of the system are removed using Schur decomposition. The identified system is then augmented such that the unknown torque input is modeled as a state changed by a random process noise. This augmented system is used to create a Kalman Observer, which compensates the spindle dynamics and estimates the torque from the spindle nominal current. The Kalman Observer is tuned automatically by estimating the noise covariance values using machining simulations. The method was eventually validated on a Quaser UX 600 industrial CNC system.

description: Quantum computation and communication protocols require quantum resources which are in the continuous variable regime squeezed and/or quadrature entangled optical modes. To perform more and more complex and robust protocols, one needs sources that can produce in a controlled way highly multimode quantum states of light. One possibility is to mix different single mode quantum resources. Another is to directly use a multimode device, either in the spatial or in the frequency domain. We present here the first experimental demonstration of a device capable of producing simultanuously several squeezed transverse modes of the same frequency and which is potentially scalable. We show that this device, which is an Optical Parametric Oscillator using a self-imaging cavity, produces a multimode quantum resource made of three squeezed transverse modes.

description: We study the magnetosphere of a slowly rotating magnetized neutron star subject to toroidal oscillations in the relativistic regime. Under the assumption of a zero inclination angle between the magnetic moment and the angular momentum of the star, we analyze the Goldreich-Julian charge density and derive a second-order differential equation for the electrostatic potential. The analytical solution of this equation in the polar cap region of the magnetosphere shows the modification induced by stellar toroidal oscillations on the accelerating electric field and on the charge density. We also find that, after decomposing the oscillation velocity in terms of spherical harmonics, the first few modes with $m=0,1$ are responsible for energy losses that are almost linearly dependent on the amplitude of the oscillation and that, for the mode $(l,m)=(2,1)$, can be a factor $\sim8$ larger than the rotational energy losses, even for a velocity oscillation amplitude at the star surface as small as $η=0.05 \ Ω\ R$. The results obtained in this paper clarify the extent to which stellar oscillations are reflected in the time variation of the physical properties at the surface of the rotating neutron star, mainly by showing the existence of a relation between $P\dot{P}$ and the oscillation amplitude. Finally, we propose a qualitative model for the explanation of the phenomenology of intermittent pulsars in terms of stellar oscillations that are periodically excited by star glitches.

description: We calculate from first principles the O1s core-level shifts for a variety of atomistic models of the interface between TiO2 and the dye N3 found in dye-sensitized solar cells. A systematic comparison between our calculations and published photoemission data shows that only interface models incorporating hydrogen bonding between the dyes are compatible with experiment. Based on our analysis we propose that at the TiO2/N3 interface the dyes are arranged in supramolecular assemblies. Our work opens a new direction in the modeling of semiconductor/dye interfaces and bears on the design of more efficient nanostructured solar cells.

description: Recently, the AlB2-type compounds (such as AlB2 and MgB2) which exhibit Dirac Nodal Line (DNLs) semimetal on their electronic band structure and Phononic Weyl Nodal Straight Lines (PTWNLs) on their phonon spectrum, have received wide attentions on their novel properties. Up to date, no comparative studies have been investigated on their electronic structures, phonon spectrum, and electron phonon coupling (EPC) under the conditions of carrier doping and strain engineering. Here, we systemically investigate their above properties under carrier doping and strain engineering by first-principles calculations. The results show that the superconducting transition temperature Tc can be enhanced by electron doping and tensile strain. For AlB2, the tensile strain of 6% can enhance Tc to 10.25 K and with the doping concentrate of 0.1 e- per cell can enhance Tc reach to 9.89 K. Moreover, the physical quantities related to superconductivity of AlB2 are more affected by carrier doping than MgB2. Our results provide a theoretical reference to explore the correlation between electronic and phonon topological properties in AlB2-type materials.

description: In this paper, the scheme of quantum computing based on Stark chirped rapid adiabatic passage (SCRAP) technique [L. F. Wei et al., Phys. Rev. Lett. 100, 113601 (2008)] is extensively applied to implement the quantum-state manipulations in the flux-biased Josephson phase qubits. The broken-parity symmetries of bound states in flux-biased Josephson junctions are utilized to conveniently generate the desirable Stark-shifts. Then, assisted by various transition pulses universal quantum logic gates as well as arbitrary quantum-state preparations could be implemented. Compared with the usual PI-pulses operations widely used in the experiments, the adiabatic population passage proposed here is insensitive the details of the applied pulses and thus the desirable population transfers could be satisfyingly implemented. The experimental feasibility of the proposal is also discussed.

description: Since security is one of the most important issues, the evolve of cryptography and cryptographic analysis are considered as the fields of on-going research. The latest development on this field is DNA cryptography. It has emerged after the disclosure of computational ability of Deoxyribo Nucleic Acid (DNA). DNA cryptography uses DNA as the computational tool along with several molecular techniques to manipulate it. Due to very high storage capacity of DNA, this field is becoming very promising. Currently it is in the development phase and it requires a lot of work and research to reach a mature stage. By reviewing all the potential and cutting edge technology of current research, this paper shows the directions that need to be addressed further in the field of DNA cryptography.

description: We investigate the properties of the Lieb lattice, i.e a face-centered square lattice, subjected to external gauge fields. We show that an Abelian gauge field leads to a peculiar quantum Hall effect, which is a consequence of the single Dirac cone and the flat band characterizing the energy spectrum. Then we explore the effects of an intrinsic spin-orbit term - a non-Abelian gauge field - and demonstrate the occurrence of the quantum spin Hall effect in this model. Besides, we obtain the relativistic Hamiltonian describing the Lieb lattice at low energy and derive the Landau levels in the presence of external Abelian and non-Abelian gauge fields. Finally, we describe concrete schemes for realizing these gauge fields with cold fermionic atoms trapped in an optical Lieb lattice. In particular, we provide a very efficient method to reproduce the intrinsic (Kane-Mele) spin-orbit term with assisted-tunneling schemes. Consequently, our model could be implemented in order to produce a variety of topological states with cold-atoms.

description: Based on an evidence review, the Centre for Lebanese Studies formulated a research agenda for education in the context of conflict and protracted crises in Lebanon. The research agenda is summarised in this working paper as part of the Education Research in Conflict and Protracted Crisis (ERICC) programme. Based on a review of existing evidence and knowledge as well as consultations with stakeholders in the education sector, the paper focuses on micro and macro levels of educational processes by engaging with pre-existing conditions, drivers of learning and development, and outcomes. The paper first introduces the context of education in conflict and protracted crises in Lebanon and describes the process of formulating a general research agenda with a particular emphasis on identification of research gaps and the participatory approach used for national-level consultations. The paper then introduces and describes the eight themes of the research agenda: Governance and financial management; Teachers; Crisis monitoring; Private Sector; Non-formal education; Vocational education; Knowledge production; Crisis in Southern Lebanon. The research projects will broadly focus on Governance, Teachers, and Crisis Monitoring.

description: Ho condotto una ricerca di tipo qualitativo nella mia classe di pratica, una III-IV-V elementare di quindici bambini. Ho scelto di proporre una ricerca nell’ambito della scrittura, in particolare della riscrittura. Dopo la prova in entrata, mi sono resa conto che non tutti gli allievi sapevano come strutturare un testo nelle tre parti principali; per questo motivo nel corso degli interventi abbiamo lavorato sulla struttura testuale partendo dall’albo illustrato Piccolo blu e piccolo giallo di Leo Lionni. Gli allievi, divisi in coppie miste in base al livello di competenza emerso nella prova in entrata, hanno riscritto e ricreato l’albo seguendo consegne diverse in base alle problematiche emerse. Ho poi proposto una prova in uscita per trarre le mie conclusioni e vedere se effettivamente vi era un’evoluzione delle competenze dei bambini. Mi sono subito accorta che non tutti gli allievi hanno strutturato un testo completo nella prova in uscita; nonostante ciò, ognuno ha comunque migliorato almeno in parte le sue competenze. Infatti, nessun allievo ha consegnato un testo in cui vi fosse unicamente lo svolgimento e più della metà ha scritto una storia in cui vi fosse un inizio, uno svolgimento e un finale. Questo mi fa capire che lavorare con la strategia della riscrittura, in particolare di un albo illustrato, porta gli allievi a migliorare le loro competenze per quanto riguarda la struttura del testo narrativo.

description: Stencil computations consume a major part of runtime in many scientific simulation codes. As prototypes for this class of algorithms we consider the iterative Jacobi and Gauss-Seidel smoothers and aim at highly efficient parallel implementations for cache-based multicore architectures. Temporal cache blocking is a known advanced optimization technique, which can reduce the pressure on the memory bus significantly. We apply and refine this optimization for a recently presented temporal blocking strategy designed to explicitly utilize multicore characteristics. Especially for the case of Gauss-Seidel smoothers we show that simultaneous multi-threading (SMT) can yield substantial performance improvements for our optimized algorithm.

A Computational Thinking Integration Model for K–12
Creators: name: Azeka, Steven

Publisher: name: Zenodo
Year: 2021

description: Computational thinking (CT) has grown in popularity over the last few decades, with an increasing number of K–12 educators integrating CT into their classrooms. States are catalyzing this effort through the development of state computer science standards, many of which include CT. For example, by 2024, all students in New York State will be exposed to some form of CT. However, existing resources and support often lack a sequential model outlining the different stages of CT integration. In this presentation, we will share our newly developed Computational Thinking Integration Model (CTIM). In this model, teachers start by integrating CT in an unplugged setting, transition to computational modeling, and finally introduce the basics of computer science. The presentation will include examples of each stage and how CT can integrate into different content areas. We also plan on leading a discussion around the topic to get participant feedback on the model.

description: We present a contemporary perspective on the String Landscape and the Multiverse of plausible string, M- and F-theory vacua, seeking to demonstrate a non-zero probability for the existence of a universe matching our own observed physics within the solution ensemble, arguing for the importance of No-Scale Supergravity as an essential common underpinning. Our context is a highly detailed phenomenological probe of No-Scale F-SU(5), a model representing the intersection of the F-lipped SU(5) X U(1)_X Grand Unified Theory (GUT) with extra TeV-Scale vector-like multiplets derived out of F-theory, and the dynamics of No-Scale Supergravity. We present a highly constrained "Golden" region with tan(beta) \sim 15, m_t = 173.0 - 174.4 GeV, M_1/2 = 455 - 481 GeV, and M_V = 691 - 1020 GeV, which simultaneously satisfies all known experimental constraints. We supplement this bottom-up phenomenological perspective with a top-down theoretical analysis of the one-loop effective Higgs potential, achieving a striking consonance via the dynamic determination of tan(beta) and M_1/2 at the local secondary minimization of the spontaneously broken electroweak Higgs vacuum V_min. We present the distinctive signatures of No-Scale F-SU(5) at the LHC, where a light stop and gluino are expected to generate a surplus of ultra-high multiplicity (>= 9) hadronic jet events. We propose modest alterations to the canonical background selection cut strategy which would enhance resolution of these events, while readily suppressing the contribution of all Standard Model processes, and allowing a clear differentiation from competing models of new physics. Detection by the LHC of the ultra-high jet signal would constitute a suggestive evocation of the intimately linked stringy origins of F-SU(5), and could provide a glimpse into the fundamental string moduli, and possibly even the workings of the No-Scale Multiverse.
