description: Gold Fields La Cima S.A. (GFLC) owns the Cerro Corona gold and copper mine in the Cajamarca district of Peru. MWH has been providing design and construction support services to GFLC since 2006. The Tailing Storage Facility (TSF) includes a centerline constructed rockfill dam with a low permeability core zone and a proposed ultimate height of 160 meters. Upstream stability of the dam was a specific focus of the design and required characterization of the impounded tailings near the upstream face of the dam. The tailings deposition environment at the facility has varied with time, being largely subaqueous during initial facility filling, then fluctuating between subaerial and subaqueous due to variations in pond level, and more recently achieving a subaerial beach of increasing length. Three investigation programs, which included sampling, vane shear testing (VST), and cone penetration testing (CPT), have been performed to characterize the impounded tailings for design purposes. This paper presents a summary of these programs and their influence on the design. It also discusses the apparent influence on the deposition environment on the deposited tailing characteristics and the development of a variable, site-specific cone factor (Nkt) for use in estimating peak undrained shear strength(Su) from the CPT data.
Z$ decay into a bottom quark, a light sbottom and a light gluino

description: The discrepancy between the measured and theoretical production cross section of $b$ quarks at the Tevatron can probably be explained by the recently proposed scenario of light gluinos of mass 12-16 GeV and light sbottoms of mass $2-5.5$ GeV. In this scenario, we study a related process at the $Z$ pole, $Z \to b \tilde{b}_1^* \tilde{g} + \bar b \tilde{b}_1 \tilde{g}$ followed by $\tilde{g} \to b \tilde{b}_1^* / \bar b \tilde{b}_1$. The hadronic branching ratio for this channel is $(1-3) \times 10^{-3}$, which is of order of the size of the uncertainty in $R_b$. We find that a typical event consists of an energetic prompt bottom-jet back-to-back with a ``fat'' bottom-jet, which consists of a bottom quark and two bottom squarks. Such events with a $10^{-3}$ branching ratio may affect the measurement of $R_b$; even more interesting if the ``fat'' bottom jet can be identified.

Stable Multithreading: A New Paradigm for Reliable and Secure Threads
Creators: Cui, Heming
Publisher: name: Columbia University
Year: 2015
Subjects: Computer science

description: Multi threaded programs have become pervasive and critical due to the rise of the multi core hardware and the accelerating computational demand. Unfortunately, despite decades of research and engineering effort, these programs remain notoriously difficult to get right, and they are plagued with harmful concurrency bugs that can cause wrong outputs, program crashes, security breaches, and so on. Our research reveals that a root cause of this difficulty is that multithreaded programs have too many possible thread interleavings (or schedules) at runtime. Even given only a single input, a program may run into a great number of schedules, depending on factors such as hardware timing and OS scheduling. Considering all inputs, the number of schedules is even much greater. It is extremely challenging to understand, test, analyze, or verify this huge number of schedules for a multi threaded program and make sure that all these schedules are free of concurrency bugs. Thus, multi threaded programs are extremely difficult to get right.

To reduce the number of possible schedules for all inputs, we looked into the relation between inputs and schedules of real-world programs, and made an exciting discovery: many programs need only a small set of schedules to efficiently process a wide range of inputs! Leveraging this discovery, we have proposed a new idea called Stable Multithreading (or StableMT) that reuses each schedule on a wide range of inputs, greatly reducing the number of possible schedules for all inputs. By addressing the root cause that makes multithreading difficult to get right, StableMT makes understanding, testing, analyzing, and verification of multithreaded programs much easier. To realize StableMT, we have built three StableMT systems, TERN, PEREGRINE, and PARROT, with each addressing a distinct research challenge. Evaluation on a wide range of 108 popular multithreaded programs with our latest StableMT system, PARROT, shows that StableMT is simple, fast, and deployable. All PARROT's source code, entire benchmarks, and raw evaluation results are available at http://github.com/columbia/smt-mc.

To encourage deployment, we have applied StableMT to improve several reliability techniques, including: (1) making reproducing real world concurrency bugs much easier;  (2) greatly improving the precision of static program analysis, leading to the detection of several new harmful data races in heavily tested programs; and (3) greatly increasing the coverage of model checking, a systematic testing technique, by many orders of magnitudes. StableMT has attracted the research community's interests, and some techniques and ideas in our StableMT systems have been leveraged by other researchers to compute a small set of schedules to cover all or most inputs for multi threaded programs.

description: The stable envelope for symplectic resolutions, constructed by Maulik and Okounkov, is a key ingredient in their work on quantum cohomology and quantum K-theory of Nakajima quiver varieties. In this thesis, we study the various aspects of the cohomological stable basis for the cotangent bundle of flag varieties. We compute its localizations, use it to calculate the quantum cohomology of the cotangent bundles, and relate it to the Chern--Schwartz--MacPherson class of Schubert cells in the flag variety.

description: Es wurden gemäß den Reaktionsgleichungen 2-5 zehn bisher unbekannte Silylharnstoffe R(CH3)2Si-NH-CO-NR'R" dargestellt, unter Variation von R=CH3, C6H5 und p-CH3C6H4 sowie von NR'R" unter Heranziehung primärer, sekundärer und cyclischer Amine. Auch die gemäß Rk.5 als Ausgangsverbindungen benötigten Silyl-N-cyanate mit R=C6H5 und p-CH3C6H4 waren zuvor nicht bekannt. Die Absicherung der Strukturen der neuen Verbindungen erfolgte über Elementaranalysen, Protonenresonanz-, Infrarot- und Massenspektren. Nonamethylcyclotrisilazan [-(CH3)NSi(CH3)2-]3 (A1), Octamethylcyclotetrasilazan [-HNSi(CH3)2-]4 (A2) und Dodecamethylcyclotetrasilazan [-(CH3)NSi(CH3)2-]4 (A3) zeigten bei Verfütterung an Mäusen letale Wirkung von etwa 1.5 g/kg an, beeinflußten einen Strychnin- wie einen Pentetrazolkrampf synergistisch, erhöhten bei Zugabe die Dauer einer Hexobarbitalnarkose bis auf das Doppelte und zeigten auch analgetische Wirkung. Die blutzuckersenkende Wirkung des Silylharnstoffs C3 entsprach mit maximal rund 35% Abnahme des Ausgangswertes bei einer Dosierung von 440 mg/kg in etwa der des Tolbutamidnatriums (Rastinon) bei einer Dosierung von 100 mg/kg. Die Dosierung von je 250 mg/kg des Cyclotrisilazans A1 sowie der Silylharnstoffe B5 und C3 senkte den Blutzuckerspiegel um etwa 15% ab, entsprechend einer Tolbutamid-natrium-Dosierung von 25 mg/kg.

The parent compounds R(CH3)2SiNCO from equation 5 had to be prepared also for the first time with R=C6H5 and p-CH3C6H4. Confirmation of structure of the new compounds was achieved by elemental analysis, proton nmr, infrared and mass spectra. Nonamethylcyclotrisilazane [-(CH3)NSi( CH3)2-]3 (A1), octamethylcyclotetrasilazane [-HNSi(CH3)2-]4 (A2) and dodecamethylcyclotetrasilazane [-(CH3)NSi(CH3)2-]4 (A3) showed on feeding of mice lethal effectiveness beginning with 1.5 g/kg, influenced synergistically convulsions caused by strychnine or by pentetrazole, dublicated the durance of hexobarbital narcosis and showed also analgetic effectiveness. In effectiveness of lowering of blood sugar levels the silyl urea C3 showed a maximum with 35% decrease of the normal level at 440 mg/kg dosage, equal to 100 mg/kg dosage of tolbutamide-sodium (Rastinon). Dosage of 250 mg/kg each of the cyclotrisilazane A1 as well as of the silyl ureas B5 and C3 decreased the blood sugar level by approximately 15%, equal to 25 mg/kg tolbutamide-sodium dosage.

description: Entropy numbers are an important tool for quantifying the compactness of operators. Besides establishing new upper bounds on the entropy numbers of diagonal operators $D_σ$ from $\ell_p$ to $\ell_q$, where $p\not=q$, we investigate the optimality of these bounds. In case of $pq$ we show optimality under weaker assumption than previously used in the literature. In addition, we illustrate the benefit of our results with examples not covered in the literature so far.

A valid species, Tenthredo (Temuledo) galerita (Konow, 1907).
Types. Sciopteryx [sic!] galerita Konow, 1907b: 164–165. Syntype (s) ♀, “ Sikkim ”. Lectotype ♀, hereby designated, (MNCN_ Ent 100245, MNCN Cat. Tipos Nº 8132, Fig. 23, see also http://dx.doi.org/10.6084/ m9.figshare.779756). Type locality: India, Sikkim.
Discussion. The species was not treated by Malaise (1945). Saini (2007: 11) noted: “For want of detailed account and difficulty in translating, T. galerita (Konow) could not be inducted into the key.” Benson (1968: 187) examined the type specimen, and placed it in Tenthredo. Tenthredo galerita shows similarities with T. religosa Malaise, 1945, and T. contraria Malaise, 1945. Currently, it should be placed in the subgenus Temuledo Zhelochovtsev, 1988.

description: This paper studies the decay of a large, closed domain wall in a closed universe. Such walls can form in the presence of a broken, discrete symmetry. We introduce a novel process of quantum decay for such a wall, in which the vacuum fluctuates from one discrete state to another throughout one half of the universe, so that the wall decays into pure field energy. Equivalently, the fluctuation can be thought of as the nucleation of a second domain wall of zero size, followed by its growth by quantum tunnelling and its collision with the first wall, annihilating both. The barrier factor for this quantum tunneling is calculated by guessing and verifying a Euclidean instanton for the two-wall system. We also discuss the classical origin and evolution of closed, topologically spherical domain walls in the early universe, through a "budding-off" process involving closed domain walls larger than the Hubble radius. This paper is the first of a series on this subject.

description: Geschlossene und proprietäre Infrastrukturen schränken den Zugang zu Wissenschaft mittels Paywalls stark ein. Sie verhindern jedoch auch die Wiederverwendung von Forschungsergebnissen und damit, dass andere Tools auf ihren Inhalten, Daten und ihrer Software aufbauen. Am Beispiel von Google Scholar werde ich erläutern, wie diese Eigenschaften geschlossener Infrastrukturen Lock-In-Effekte erzeugen und Innovation verhindern. Ich werde auch zeigen, wie offene Infrastrukturen uns dabei helfen können, diese Probleme zu lösen. Ziel ist es, ein Ökosystem zu schaffen, das sich im Eigentum der wissenschaftlichen Community befindet und von ihr gesteuert wird. In diesem Ökosystem gedeihen Innovationen, da Eintrittsbarrieren beseitigt werden und Systeme einzelne Komponenten anderer Systeme wiederverwenden können. Besonders eingehen werde ich dabei auf Open Source-Frontends, da diese die Art und Weise darstellen, wie ForscherInnen mit Open Science interagieren.

Entanglement negativity as a universal non-Markovianity witness

description: In order to engineer an open quantum system and its evolution, it is essential to identify and control the memory effects. These are formally attributed to the non-Markovianity of dynamics that manifests itself by the evolution being indivisible in time, a property which can be witnessed by a non-monotonic behavior of contractive functions or correlation measures. We show that by monitoring directly the entanglement behavior of a system in a tripartite setting it is possible to witness all invertible non-Markovian dynamics, as well as all (also non-invertible) qubit evolutions. This is achieved by using negativity, a computable measure of entanglement, which in the usual bipartite setting is not a universal non-Markovianity witness. We emphasize further the importance of multipartite states by showing that non-Markovianity cannot be faithfully witnessed by any contractive function of single qubits. We support our statements by an explicit example of eternally non-Markovian qubit dynamics, for which negativity can witness non-Markovianity at arbitrary time scales.

description: We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a pi+ pi- pair. We calculate these asymmetries originating from both longitudinal and transverse polarizations of the virtual photon in the framework of QCD and in the Born approximation, in a kinematical domain accessible to HERA experiments. We predict a sizable charge asymmetry with a characteristic dependence on the invariant mass of the pi+ pi- pair, which makes this observable very important for establishing the magnitude of the Odderon exchange in hard processes. The single spin asymmetry turns out to be rather small. We briefly discuss future improvements of our calculations and their possible effects on the results.

description: Accurate predictions for the non-linear matter power spectrum are needed to confront theory with observations in current and near future weak lensing and galaxy clustering surveys. We propose a computationally cheap method to create an emulator for modified gravity models by utilizing existing emulators for $Λ$CDM. Using a suite of $N$-body simulations we construct a fitting function for the enhancement of both the linear and non-linear matter power spectrum in the commonly studied Hu-Sawicki $f(R)$ gravity model valid for wave-numbers $k \lesssim 5-10\, h\text{Mpc}^{-1}$ and redshifts $z \lesssim 3$. We show that the cosmology dependence of this enhancement is relatively weak so that our fit, using simulations coming from only one cosmology, can be used to get accurate predictions for other cosmological parameters. We also show that the cosmology dependence can, if needed, be included by using linear theory, approximate $N$-body simulations (such as COLA) and semi-analytical tools like the halo model. Our final fit can easily be combined with any emulator or semi-analytical models for the non-linear $Λ$CDM power spectrum to accurately, and quickly, produce a non-linear power spectrum for this particular modified gravity model. The method we use can be applied to fairly cheaply construct an emulator for other modified gravity models. As an application of our fitting formula we use it to compute Fisher-forecasts for how well galaxy clustering and weak lensing in a Euclid-like survey will be at constraining modifications of gravity.

description: This dissertation makes a case for the Shakespearean stage in the modern Anglo-American tradition as a distinctive laboratory for producing and navigating theories of emotion. The dissertation brings together Shakespeare performance studies and the newer fields of the history of emotions and cultural emotion studies, arguing that Shakespeare’s enduring status as the playwright of human emotion makes the plays in performance critical sites of discourse about human emotion. More specifically, the dissertation charts how, since the late nineteenth century, Shakespeare performance has been implicated in an effort to understand emotion as it defines and relates to the “human” subject. The advent of scientific materialism and Darwinism involved a dethroning of emotion and its expression as a specially endowed human faculty, best evidenced by Charles Darwin’s 1871 The Expression of Emotion in Man and Animals. Shakespeare’s poetic, formal expression of the passions was seen as proof of this faculty, and nowhere better exemplified than in the tragedies and in the passionate displays of the great tragic heroes. The controversy surrounding the tragic roles of the famous Victorian actor-manager Henry Irving illustrates how the embodied, human medium of the Shakespearean stage served as valuable leverage in contemporary debates about emotion. The dissertation then considers major Shakespearean figures of the twentieth century, including Harley Granville Barker, Orson Welles, Laurence Olivier, and Peter Brook, whose “stages” similarly galvanize and reflect contestation and change in what William Reddy has called “emotional regimes” or Barbara Rosenwein “emotional communities.” For each of these figures, a specific emotional paradigm is at stake in staging Shakespeare and particularly Shakespearean tragedy. I engage with a range of sources, from performance reviews to popular psychology, to locate these canonical moments in Shakespearean performance history as flashpoints in a cultural history of emotion.

description: This dissertation contributes to the study of a queueing system with a single pool of multiple homogeneous servers to which multiple classes of customers arrive in independent streams. The objective is to devise appropriate staffing and scheduling policies to achieve specified class-dependent service levels expressed in terms of tail probability of delays. Here staffing and scheduling are concerned with specifying a time-varying number of servers and assigning newly idle servers to a waiting customer from one of K classes, respectively. For this purpose, we propose new staffing-and-scheduling solutions under the critically-loaded and overloaded regimes. In both cases, the proposed solutions are both time dependent (coping with the time variability in the arrival pattern) and state dependent (capturing the stochastic variability in service and arrival times). We prove heavy-traffic limit theorems to substantiate the effectiveness of our proposed staffing and scheduling policies. We also conduct computer simulation experiments to provide engineering confirmation and practical insight.

description: Audio tagging is the task of predicting the presence or absence of sound classes within an audio clip. Previous work in audio tagging focused on relatively small datasets limited to recognising a small number of sound classes. We investigate audio tagging on AudioSet, which is a dataset consisting of over 2 million audio clips and 527 classes. AudioSet is weakly labelled, in that only the presence or absence of sound classes is known for each clip, while the onset and offset times are unknown. To address the weakly-labelled audio tagging problem, we propose attention neural networks as a way to attend the most salient parts of an audio clip. We bridge the connection between attention neural networks and multiple instance learning (MIL) methods, and propose decision-level and feature-level attention neural networks for audio tagging. We investigate attention neural networks modeled by different functions, depths and widths. Experiments on AudioSet show that the feature-level attention neural network achieves a state-of-the-art mean average precision (mAP) of 0.369, outperforming the best multiple instance learning (MIL) method of 0.317 and Google's deep neural network baseline of 0.314. In addition, we discover that the audio tagging performance on AudioSet embedding features has a weak correlation with the number of training samples and the quality of labels of each sound class.

description: This thesis covers two topics of robotic grasping: stable grasping and semantic grasping.  The first part of the thesis is dedicated to the stable grasping problem, where we focus on a grasping pipeline that robustly executes a planned-to-be stable grasp under uncertainty.  To this end, we first present a learning method which estimates the stability of a grasp based on tactile feedback and hand kinematic data.  We then show our hand adjustment algorithm which works with the grasp stability estimator and synthesizes hand adjustments to optimize a grasp towards a stable one.  With these two methods, we obtain a grasping pipeline with a closed-loop grasp adjustment process which increases the grasping performance under uncertainty. The second part of the thesis considers how robotic grasping should be accomplished to facilitate a manipulation task that follows the grasp.  Certain task-related constraints should be satisfied by the grasp in use, which we refer to as semantic constraints.  We first develop an example-based method to encode semantic constraints and to plan stable grasps according to the encoded semantic constraints.  We then design a task description framework to abstract an object manipulation task.  Within this framework, we also present a method which could automatically construct this manipulation task abstraction from a human demonstration.
Lorentz Invariance and the Cosmological Constant

description: Non-trivial solutions in string field theory may lead to the spontaneous breaking of Lorentz invariance and to new tensor-matter interactions. It is argued that requiring the contribution of the vacuum expectation values of Lorentz tensors to account for the vacuum energy up to the level that $Ω_{0}^Λ = 0.5$ implies the new interactions range is $λ\sim 10^{-4} m$. These conjectured violations of the Lorentz symmetry are consistent with the most stringent experimental limits.

description: Before reading this thesis, one must understand what the role of a stage manager entails. In The Backstage Guide to Stage Management 2 nd Edition, Tom Kelly has created his own definition that identifies the persona and skills of a stage manager. To fully understand the role, and observer must first grasp that although stage managers may have similar functions and job descriptions, no two positions are the same. It depends on the role they are partaking in and whether or not they abide under a particular contract or union. Stage Managers are responsible and adaptable communicators who have the ability to handle and coordinate diverse groups of artistic personalities with tactful discipline and a sense of humor. They establish a creative environment by combining the ability to prioritize and anticipate and solve problems, with calm sensitivity and grace under pressure. Their ability to do the above stems from organizational ability, acquired technical knowledge (sound, music, lights, design, and construction, typing, use of computers, and so on), familiarity with union requirements, and an inspirational personality that creates positive energy". In effort to elaborate on the practical application of the above definition, this thesis will feature the experience of an Assistant Stage Manager (ASM) for Disney Cruise Line (DCL) on the Disney Dream ship. It will also describe in detail the training procedures for this position; compare the ASM role on a ship to a trained assistant stage manager on land, and assess the external factor of life on board a cruise ship. The responsibilities discussed will include the following: time commitment required of a Disney Cruise Line ASM, paperwork created, challenges faced, direct reports, rehearsals, challenging weather conditions, and the benefits of ship work to young stage managers. This thesis will maintain a focus on Disney etiquette and the importance of keeping the magic of Disney alive while at all times providing an excellent show.

Mass-imbalanced atoms in a hard-wall trap: an exactly solvable model with emergent $D_{6}$ symmetry

description: We show that a system consisting of two interacting particles with mass ratio $3$ or $1/3$ in a hard-wall box can be exactly solved by using Bethe-type ansatz. The ansatz is based on a finite superposition of plane waves associated with a dihedral group $D_{6}$, which enforces the momentums after a series of scattering and reflection processes to fulfill the $D_{6}$ symmetry. Starting from a two-body elastic collision model in a hard-wall box, we demonstrate how a finite momentum distribution is related to the $D_{2n}$ symmetry for permitted mass ratios. For a quantum system with mass ratio $3$, we obtain exact eigenenergies and eigenstates by solving Bethe-type-ansatz equations for arbitrary interaction strength. A many-body excited state of the system is found to be independent of the interaction strength, i.e. the wave function looks exactly the same for non-interacting two particles or in the hard-core limit.

description: Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool that provides excellent soft-tissue contrast without the use of ionizing radiation. Compared to other clinical imaging modalities (e.g., CT or ultrasound), however, the data acquisition process for MRI is inherently slow, which motivates undersampling and thus drives the need for accurate, efficient reconstruction methods from undersampled datasets. In this article, we describe the use of "plug-and-play" (PnP) algorithms for MRI image recovery. We first describe the linearly approximated inverse problem encountered in MRI. Then we review several PnP methods, where the unifying commonality is to iteratively call a denoising subroutine as one step of a larger optimization-inspired algorithm. Next, we describe how the result of the PnP method can be interpreted as a solution to an equilibrium equation, allowing convergence analysis from the equilibrium perspective. Finally, we present illustrative examples of PnP methods applied to MRI image recovery.
