The Violation of the Taylor Hypothesis in Measurements of Solar Wind Turbulence

description: Motivated by the upcoming Solar Orbiter and Solar Probe Plus missions, qualitative and quantitative predictions are made for the effects of the violation of the Taylor hypothesis on the magnetic energy frequency spectrum measured in the near-Sun environment. The synthetic spacecraft data method is used to predict observational signatures of the violation for critically balanced Alfvénic turbulence or parallel fast/whistler turbulence. The violation of the Taylor hypothesis can occur in the slow flow regime, leading to a shift of the entire spectrum to higher frequencies, or in the dispersive regime, in which the dissipation range spectrum flattens at high frequencies. It is found that Alfvénic turbulence will not significantly violate the Taylor hypothesis, but whistler turbulence will. The flattening of the frequency spectrum is therefore a key observational signature for fast/whistler turbulence.

description: The potential benefit of migrating software design from Structured to Object Oriented Paradigm is manifolded including modularity, manageability and extendability. This design migration should be automated as it will reduce the time required in manual process. Our previous work has addressed this issue in terms of optimal graph clustering problem formulated by a quadratic Integer Program (IP). However, it has been realized that solution to the IP is computationally hard and thus heuristic based methods are required to get a near optimal solution. This paper presents a Genetic Algorithm (GA) for optimal clustering with an objective of maximizing intra-cluster edges whereas minimizing the inter-cluster ones. The proposed algorithm relies on fitness based parent selection and cross-overing cluster elements to reach an optimal solution step by step. The scheme was implemented and tested against a set of real and synthetic data. The experimental results show that GA outperforms our previous works based on Greedy and Monte Carlo approaches by 40% and 49.5%.

description: We study the speed/fidelity trade-off for a two-qubit phase gate implemented in $^{43}$Ca$^+$ hyperfine trapped-ion qubits. We characterize various error sources contributing to the measured fidelity, allowing us to account for errors due to single-qubit state preparation, rotation and measurement (each at the $\sim0.1\%$ level), and to identify the leading sources of error in the two-qubit entangling operation. We achieve gate fidelities ranging between $97.1(2)\%$ (for a gate time $t_g=3.8μ$s) and $99.9(1)\%$ (for $t_g=100μ$s), representing respectively the fastest and lowest-error two-qubit gates reported between trapped-ion qubits by nearly an order of magnitude in each case.

description: The inclusive hadronic production of $η_Q$($η_c$ or $η_b$) pair is proposed to extract the transverse momentum dependent(TMD) gluon distribution functions. We use nonrelativistic QCD(NRQCD) for the production of $η_Q$. Under nonrelativistic limit TMD factorization for this process is assumed to make a lowest order calculation. For unpolarized initial hadrons, unpolarized and linearly polarized gluon distributions can be extracted by studying different angular distributions.

description: Superconductivity or metallic state may coexist with density wave ordering at imperfect nesting of the Fermi surface. In addition to the macroscopic spatial phase separation, there are, at least, two possible microscopic structures of such coexistence: (i) the soliton-wall phase and (ii) the ungapped Fermi-surface pockets. We show that the conductivity anisotropy allows to distinguish between these two microscopic density-wave structures. The results obtained may help to analyze the experimental observations in layered organic metals (TMTSF)$_{2}$PF$_{6}$, (TMTSF)$_{2}$ClO$_{4}$, $α$-(BEDT-TTF)$_{2}$KHg(SCN)$_{4}$ and in other compounds.

The Exact Foldy-Wouthuysen Transformation for a Dirac Theory with the complete set of CPT-Lorentz violating terms

description: The exact Foldy-Wouthuysen transformation is performed in order to study the Dirac field interacting with many possible external fields associated with CPT-Lorentz violation. We also derived the calculation of equations of motion as well as the generalized Lorentz force corrected by the mentioned external fields. The main point is the interaction between the Dirac particle and the terms that have the multiplication of electromagnetic field and the terms that break CPT-Lorentz. Finally, with the transformed Hamiltonian we were able to write an expression for the bound state of the theory and analyze it in the atomic experiments context. This result is an analytical expression that gives the possibility of the weakness of CPT/Lorentz terms to be compensated by the presence of a strong magnetic field.

Complementarity, quantum erasure and delayed choice with modified Mach-Zehnder interferometers

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: Often cited dictums in Quantum Mechanics include "observation disturbance causes loss of interference" and "ignorance is interference". In this paper we propose and describe a series of experiments with modified Mach-Zehnder interferometers showing that one has to be careful when applying such dictums. We are able to show that without interacting in any way with the light quantum (or quanta) expected to behave "wave-like", interference fringes can be lost by simply gaining (or having the potential to gain) the which-path knowledge. Erasing this information may revive the interference fringes. Delayed choice can be added, arriving to an experiment in line with Wheeler's original proposal. We also show that ignorance is not always synonym with having the interference fringes. The often-invoked "collapse of the wavefunction" is found to be a non-necessary ingredient to describe our experiments.

description: Energy relaxation of hot Dirac fermions in bilayer epitaxial graphene is experimentally investigated by magnetotransport measurements on Shubnikov-de Haas oscillations and weak localization. The hot-electron energy loss rate is found to follow the predicted Bloch-Grüneisen power-law behaviour of $T^4$ at carrier temperatures from 1.4 K up to $\sim$100 K, due to electron-acoustic phonon interactions with a deformation potential coupling constant of 22 eV. A carrier density dependence $n_e^{-1.5}$ in the scaling of the $T^4$ power law is observed in bilayer graphene, in contrast to the $n_e^{-0.5}$ dependence in monolayer graphene, leading to a crossover in the energy loss rate as a function of carrier density between these two systems. The electron-phonon relaxation time in bilayer graphene is also shown to be strongly carrier density dependent, while it remains constant for a wide range of carrier densities in monolayer graphene. Our results and comparisons between the bilayer and monolayer exhibit a more comprehensive picture of hot carrier dynamics in graphene systems.

Machine Learning for Crack Segmentation from Photogrammetric Imagery

description: 2021 - 2022
description: The aim of the study proposed in this thesis was to analyse and implement data pro- cessing procedures and algorithms to try to overcome the criticalities present in the traditional identification and segmentation of cracks on road pavements and buildings. For this purpose, algorithms were implemented in Python in order to optimise, on the one hand, the point cloud and products from the photogrammetric process and, on the other hand, the crack segmentation methodology, which is currently the most accurate in the literature. Point clouds produced by photogrammetric software are not directly usable, as they must first be processed to remove outliers and noise. The first phase of the thesis pre- sents an innovative approach that can assist survey methods by applying an AI algo- rithm to improve the accuracy of point clouds generated from UAV images. Many studies on the semantic segmentation of cracks using Machine Learning and Deep Learning techniques can be found in the relevant literature. However, this task is very challenging due to the complexity of the background, as cracks are easily confused with objects not belonging to the surface, shadows, and background textures and are also inhomogeneous. The results obtained to date are quite good, but often the accuracy of the trained model and the results achieved are evaluated using traditional metrics only. In most cases, the goal is merely to detect the occurrence of cracks. Particular attention should be paid to the thickness of the segmented crack, as the width of the crack is the main parameter for maintenance and characterizes the severity levels. The aim of our study is to optimize the crack segmentation process through the implementation of a modi- fied U-Net model-based architecture. U-Net is a network with two symmetrical branches (encoder-decoder structure). The encoder is replaced with a ResNet50 en- coder pre-trained on the ImageNet dataset. Our focus was on crack segmentation, and for this purpose, we used the Crack500 Dataset and compared the results with those obtained from the algorithm currently considered the most accurate and performant in the literature. To demonstrate the generalization of the model, two real case studies were tested by performing a UAV survey to obtain the photogrammetric models of both. The results are promising and accurate, with the shape and width of the segmented cracks closely resembling reality. [edited by Author]
Holography beyond conformal invariance and AdS isometry?

description: We suggest that the principle of holographic duality can be extended beyond conformal invariance and AdS isometry. Such an extension is based on a special relation between functional determinants of the operators acting in the bulk and on its boundary, provided that the boundary operator represents the inverse propagators of the theory induced on the boundary by the Dirichlet boundary value problem from the bulk spacetime. This relation holds for operators of general spin-tensor structure on generic manifolds with boundaries irrespective of their background geometry and conformal invariance, and it apparently underlies numerous $O(N^0)$ tests of AdS/CFT correspondence, based on direct calculation of the bulk and boundary partition functions, Casimir energies and conformal anomalies. The generalized holographic duality is discussed within the concept of the "double-trace" deformation of the boundary theory, which is responsible in the case of large $N$ CFT coupled to the tower of higher spin gauge fields for the renormalization group flow between infrared and ultraviolet fixed points. Potential extension of this method beyond one-loop order is also briefly discussed.

Elle regroupe un très large éventail d’approches et de disciplines : archéozoologie, archéobotanique, analyses chimiques, isotopiques ou moléculaires, menées à des échelles très diverses et envisagées de façon croisée. Son évolution récente est marquée par un important renouvellement tant au niveau des outils et techniques que des méthodes. Ainsi, les données bioarchéologiques peuvent être intégrées aux grandes problématiques anthropologiques : reconstitution des environnements et de la biodiversité du passé, restitution des pratiques agricoles et pastorales et compréhension des relations entre les sociétés et leur environnement.

title: Thermal rearrangements of some hydroxamic acid derivatives
Creators: name: Ankers, William B.
Publisher: name: University of Kent
Year: 2022

description: An historical survey of the thermolyses of hydroxamic acids and O-acylated hydroxamic acids is presented, and thermal rearrangements which proceed by [l,3 ]-sigmatropic and free radical shifts are reviewed, together with the phenomenon of chemically induced dynamic nuclear polarisation (CIDNP). N-Methyl hydroxamic acids are found to undergo, on distillation, a novel thermal rearrangement to the isomeric N-methyl-O-acylhydroxylamines, the thermodynamically less stable product. The rearrangement is shown to occur, at least in part, via an intermolecular mechanism involving formation of N-methylhydroxylamine and N-methyl-N,0-diacylhydroxylamine. Various O-thiocarbamoylated N-methyl hydroxamic acids are found to undergo, in solution, a thermal [l,3 ] rearrangement to the isomeric hydrosulphamine derivatives. This rearrangement, which is accompanied by appreciable fragmentation to the corres­ponding N-methyl amide, is shown to proceed largely via a pathway involving caged free radical pairs.

description: The 5th International Symposium “RE-WATER Braunschweig” focuses on "Integrated concepts". Integrated concepts for water and wastewater management involve not only technical aspects of wastewater reuse, but the merging of diverse areas such as governance, health risks, legal regulation and public acceptance as well as other aspects of water policy. The implementation of integrated water and wastewater projects will result in the long-term sustainability of our water supplies. However, the above mentioned complex connections have equal influence on both the benefits and challenges of water reuse. Challenges experienced by water reuse projects may include the demand for innovative technologies, technology transfer and implementation of novel applications as well as the need for public education and increased public acceptance. This symposium will deal with integrated planning and evaluation of water structures in settlement areas to be able to find a better balance between human needs and ecological necessities in the water sector. Furthermore the use of novel wastewater collection and cleaning systems will be presented. A special focus is put on the reuse of treated wastewater as a promising strategy to relieve water shortages and to protect natural resources. International examples for industrial and agricultural reuse of treated wastewater will be given. Hygienic aspects and nutrient recycling play an important role especially in the area of agricultural reuse. Therefore, topics such as micropollutants, disinfection and nutrient recovery will be discussed. The symposium is organised by the “Stadtentwässerung Braunschweig GmbH”. Cooperation partners are the Institute of Sanitary and Environmental Engineering of the TU Braunschweig, the Berlin Centre of Competence for Water and the “Abwasserverband Braunschweig”.

description: Helioseismic data from the HMI instrument have revealed a sunquake associated with the X1 flare SOL2014-03-29T17:48 in active region NOAA 12017. We try to discover if acoustic-like impulses or actions of the Lorentz force caused the sunquake. We analyze spectro-polarimetric data obtained with the Facility Infrared Spectrometer (FIRS) at the Dunn Solar Telescope (DST). Fortuitously the FIRS slit crossed the flare kernel close to the acoustic source, during the impulsive phase. The infrared FIRS data remain unsaturated throughout the flare. Stokes profiles of lines of Si I 1082.7 nm and He I 1083.0 nm are analyzed. At the flare footpoint, the Si I 1082.7 nm core intensity increases by a factor of several, the IR continuum increases by 4 +/- 1%. Remarkably, the Si I core resembles the classical Ca II K line's self-reversed profile. With nLTE radiative models of H, C, Si and Fe these properties set the penetration depth of flare heating to 100 +/- 100 km, i.e. photospheric layers. Estimates of the non-magnetic energy flux are at least a factor of two less than the sunquake energy flux. Milne-Eddington inversions of the Si I line show that the local magnetic energy changes are also too small to drive the acoustic pulse. Our work raises several questions: Have we "missed" the signature of downward energy propagation? Is it intermittent in time and/or non-local? Does the 1-2 s photospheric radiative damping time discount compressive modes?

description: Nell’ambito dei melanomi meritano una menzione particolare i cosiddetti melanomi sottili, di spessore ≤1 mm che, sebbene caratterizzati da un’altissima percentuale di guarigione dopo semplice escissione chirurgica, sono tuttavia in grado di metastatizzare, in una percentuale di casi del 10% circa, anche a notevole distanza di tempo dalla diagnosi; per questa ragione si rende necessaria la ricerca di biomarcatori in grado di predire la tendenza alla metastatizzazione. È stato eseguito uno studio retrospettivo su 31 pazienti, sottoposti ad asportazione di melanomi di spessore ≤1 mm; la caratterizzazione immunofenotipica delle cellule immunitarie del microambiente tumorale è stata realizzata mediante immunoistochimica con l’utilizzo dei marcatori: CD8, FOXP3, GRZ-B, PD-L1, HLA. ..

description: Let $(R, \sim )$ be the Rado graph, $Emb (R)$ the monoid of its self-embeddings, $Π(R)=\{ f[R]: f\in Emb (R)\}$ the set of copies of $R$ contained in $R$, and ${\mathcal I}_R$ the ideal of subsets of $R$ which do not contain a copy of $R$. We consider the poset $( Π(R ), \subset )$, the algebra $P (R)/{\mathcal I _R}$, and the inverse of the right Green's pre-order on $Emb (R)$, and show that these pre-orders are forcing equivalent to a two step iteration of the form $P \ast π$, where the poset $P$ is similar to the Sacks perfect set forcing: adds a generic real, has the $\aleph _0$-covering property and, hence, preserves $ω_1$, has the Sacks property and does not produce splitting reals, while $π$ codes an $ω$-distributive forcing. Consequently, the Boolean completions of these four posets are isomorphic and the same holds for each countable graph containing a copy of the Rado graph.

The spheronic toy universe: how special relativity may be visualized to emerge from a wave-nature of matter

description: We construct an idealized universe for didactic purposes. This universe is assumed to consist of absolute Euclidean space and to be filled with a classical medium which allows for sound waves. A known solution to the wave equation describing the dynamics of the medium is a standing spherical wave. Although this is a problem of classical mechanics, we demonstrate that the Lorentz transformation is required to generate a moving solution from the stationary one. Both solutions are here collectively referred to as "spherons". These spherons exhibit properties which have analogues in the physical description of matter with rest mass, among them de Broglie like phase waves and at the same time "relativistic" effects such as contraction and a speed limit. This leads to a theory of special relativity by assuming the point of view of an observer made of such spheronic "matter". The argument made here may thus be useful as a visualisation or didactic approach to the real universe, in which matter has wave-like properties and obeys the laws of special relativity.

Excavation
CIDOC CRM

description: Archaeological data repositories usually integrate excavation data archives as single data collections with restricted capacities to accommodate excavation data interoperability at the sub-collection level. This is largely due to the complexity of excavation data archives that are compiled with different tools and methodologies, use distinct conceptual descriptions at variable granularities, can often be unfinished or open-ended and may be linked to all sorts of digital data types, each with its own complicated production workflow. In the past decades, several attempts to adapt CIDOC-CRM in order to provide more explicit descriptions of the excavation domain have resulted in several model extensions (e.g. CRMarchaeo, CRMsc, CRMba). Each focuses on corresponding aspects of the excavation research process, while their combined usage holds an already demonstrated potential to support expressive data mappings at the sub-collection level. As part of the ongoing ARIADNEplus project, several CIDOC-CRM developers and domain experts have been working as a group and engaging in conceptual mapping exercises to address the practicalities of bringing excavation data descriptions together. In this presentation we will consider several issues that may be affecting the applicability of existing solutions and link these to our overall expectations/aspirations in terms of excavation data discoverability and reusability.
Crosscut-simplicial Lattices

description: We call a lattice crosscut-simplicial if the crosscut complex of every atomic interval is equal to the boundary of a simplex. Every interval of such a lattice is either contractible or homotopy equivalent to a sphere. Recently, Hersh and Meszaros introduced SB-labellings and proved that if a lattice has an SB-labelling then it is crosscut-simplicial. Some known examples of lattices with a natural SB-labelling include the join-distributive lattices, the weak order of a Coxeter group, and the Tamari lattice. Generalizing these three examples, we prove that every meet-semidistributive lattice is crosscut-simplicial, though we do not know whether all such lattices admit an SB-labelling. While not every crosscut-simplicial lattice is meet-semidistributive, we prove that these properties are equivalent for chamber posets of real hyperplane arrangements.

description: Mathematics is a critical part of much scientific research. Physics in particular weaves math extensively into its instruction beginning in high school. Despite much research on the learning of both physics and math, the problem of how to effectively include math in physics in a way that reaches most students remains unsolved. In this paper, we suggest that a fundamental issue has received insufficient exploration: the fact that in science, we don't just use math, we make meaning with it in a different way than mathematicians do. In this reflective essay, we explore math as a language and consider the language of math in physics through the lens of cognitive linguistics. We begin by offering a number of examples that show how the use of math in physics differs from the use of math as typically found in math classes. We then explore basic concepts in cognitive semantics to show how humans make meaning with language in general. The critical elements are the roles of embodied cognition and interpretation in context. Then we show how a theoretical framework commonly used in physics education research, resources, is coherent with and extends the ideas of cognitive semantics by connecting embodiment to phenomenological primitives and contextual interpretation to the dynamics of meaning making with conceptual resources, epistemological resources, and affect. We present these ideas with illustrative case studies of students working on physics problems with math and demonstrate the dynamical nature of student reasoning with math in physics. We conclude with some thoughts about the implications for instruction.

Exact Algorithms for Dominating Induced Matching Based on Graph Partition

description: A dominating induced matching, also called an efficient edge domination, of a graph $G=(V,E)$ with $n=|V|$ vertices and $m=|E|$ edges is a subset $F \subseteq E$ of edges in the graph such that no two edges in $F$ share a common endpoint and each edge in $E\setminus F$ is incident with exactly one edge in $F$. It is NP-hard to decide whether a graph admits a dominating induced matching or not. In this paper, we design a $1.1467^nn^{O(1)}$-time exact algorithm for this problem, improving all previous results. This problem can be redefined as a partition problem that is to partition the vertex set of a graph into two parts $I$ and $F$, where $I$ induces an independent set (a 0-regular graph) and $F$ induces a perfect matching (a 1-regular graph). After giving several structural properties of the problem, we show that the problem always contains some "good vertices", branching on which by including them to either $I$ or $F$ we can effectively reduce the graph. This leads to a fast exact algorithm to this problem.

description: We report the results of 870-$μ$m continuum observations, using the Large APEX Bolometer Camera (LABOCA), towards 77 class-II, 6.7-GHz methanol masers identified by the Methanol Multibeam (MMB) survey to map the thermal emission from cool dust towards these objects. These data complement a study of 630 methanol masers associated with compact dense clumps identified from the ATLASGAL survey. Compact dust emission is detected towards 70 sources, which implies a dust-association rate of 99% for the full MMB catalogue. Evaluation of the derived dust and maser properties leads us to conclude that the combined sample represents a single population tracing the same phenomenon. We find median clump masses of a few 10$^3$ M$\odot$ and that all but a handful of sources satisfy the mass-size criterion required for massive star formation. This study provides the strongest evidence of the almost ubiquitous association of methanol masers with massive, star-forming clumps. The fraction of methanol-maser associated clumps is a factor of ~2 lower in the outer Galaxy than the inner Galaxy, possibly a result of the lower metallicity environment of the former. We find no difference in the clump-mass and maser-luminosity distributions of the inner and outer Galaxy. The maser-pumping and clump-formation mechanisms are therefore likely to be relatively invariant to Galactic location. Finally, we use the ratio of maser luminosity and clump mass to investigate the hypothesis that the maser luminosity is a good indicator of the evolutionary stage of the embedded source, however, we find no evidence to support this.
