The strategies for and the performance of the CMS silicon tracking system alignment during the 2015-2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios.The CMS Collaboration, Armen R.

https://scholar.archive.org/work/balaxbo6d5e5jebvlgym6qysrm
In the production of removable facial prosthetics, Computer-Aided Design and Manufacture (CAD/CAM)is being increasingly explored. This PhD thesis investigates the application of CAD/CAM in the design and production of components that retain the prostheses to the anatomy. Conventional methods of hand-crafting the retention elements are well established butlittle research has considered producing these elementsusing CAD/CAM. A fully digital prosthetic workflow has not yet been developed, and the efficacy of using CAD/CAM for retention mechanism design and fabrication remains unclear. This study firstly focuses on defining the requirements for designing extra-oral prosthesis retention mechanisms, by mapping the various stages of conventional practiceand obtaining the opinions of practicing clinicians. Secondly, the qualitative findings are applied to develop a fully CAD/CAMprocess using existing technologies. Scanning, reverse engineering, design and fabrication technologies are trialled and samples of bar-clip mechanisms are produced. The final stage focuses on developing objective methods to evaluate aspects of bar-clip design previously limited to subjective evaluation, and to make an initial comparison of conventional and CAD/CAM bar-clip mechanisms.This focuses on measuring surface and dimensional quality, accuracy offit and clip retention forces.This study provides an increased knowledge-base of current prosthetic practice; CAD/CAM prosthesis production and evaluation methods; and insight into the attitudes of clinicians towards the integration & implementation of CAD/CAM. The thesis demonstrates that CAD/CAM can be used to design,produce, and integrate bar-clip retention mechanisms in all aspects of theprosthesis production workflow. Digital measurement methods allow an objective evaluation of the important aspects of bar-clip mechanism design, identifying a number of inaccuracies/design flaws that current evaluation techniques fail to identify.The study concludes that the overall CAD/CAM workflow is not [...]Steffan John Rhys Danielwork_balaxbo6d5e5jebvlgym6qysrmThu, 04 Aug 2022 00:00:00 GMTMulti-scale deformation characteristics and mechanism of red-bed mudstone in dry-wet environment
https://scholar.archive.org/work/purlztf4izh2lgf6vde5nqkdwm
Repeated swelling-shrinking behaviors of red-bed mudstone poses a potential threat to high-speed railways. Through swelling test and dry-wet cycle test, the deformation law of mudstone samples was discussed. Using X-ray CT scanning, MIP and BET technology, the inner relationship between deformation and structural characteristics were clarified. The results showed that the surface of sample was chipped and peeled off after two cycles. During the dehumidification, the mudstone has undergone three stages of shrinkage adjustment, accelerated shrinkage and stable shrinkage. Uneven tensile stress caused by evaporation of water molecules in the initial stage of drying delayed the shrinkage. Initial water content was opposite to the changes of stable strain after water immersion and residual strain after dehydration, while it was positively correlated with environmental temperature. Porosity and connectivity keep increasing with the continuous cycle, and the number appeared to gradually descend from the two ends to the middle in space. Successive drying and wetting promoted a wider range of diameter-length ratio by the swelling of hydrophilic minerals and uneven shrinkage stress. Spatial orientation also transitioned to the polar angle. Specifically, the structure evolved from the layered shape to the tree-like and net-like in order. Microscopic scale mainly included uniform flat pores and wedge-shaped capillary pores, ranging from 10 to 80 Å. The number of cycles didn't affect the morphology of micropores, but only caused volume and specific surface area to enlarge. The existence of clays generated irreversible deformation of micropores and initiated the gradual extension. This work will provide key data and necessary methods for the geohazard problems.Fei Yu, Kaiwen Tong, Zhenghao Fu, Gaoshun Feng, Zhe Zhou, Shanxiong Chen, Zhangjun Daiwork_purlztf4izh2lgf6vde5nqkdwmThu, 04 Aug 2022 00:00:00 GMTNon-Invertible Chiral Symmetry and Exponential Hierarchies
https://scholar.archive.org/work/yuux7oe74vdodcr4gj2qetsprm
We elucidate the fate of classical symmetries which suffer from abelian Adler-Bell-Jackiw anomalies. Instead of being completely destroyed, these symmetries survive as non-invertible topological global symmetry defects with worldvolume anyon degrees of freedom that couple to the bulk through a magnetic one-form global symmetry as in the fractional hall effect. These non-invertible chiral symmetries imply selection rules on correlation functions and arise in familiar models of massless quantum electrodynamics and models of axions (as well as their non-abelian generalizations). When the associated bulk magnetic one-form symmetry is broken by the propagation of dynamical magnetic monopoles, the selection rules of the non-invertible chiral symmetry defects are violated non-perturbatively. This leads to technically natural exponential hierarchies in axion potentials and fermion masses.Clay Cordova, Kantaro Ohmoriwork_yuux7oe74vdodcr4gj2qetsprmWed, 03 Aug 2022 00:00:00 GMTReciprocal swimming at intermediate Reynolds number
https://scholar.archive.org/work/pi74qockofegrbe7mnghe7uiyu
In Stokes flow, Purcell's scallop theorem forbids objects with time-reversible (reciprocal) swimming strokes from moving. In the presence of inertia, this restriction is eased and reciprocally deforming bodies can swim. A number of recent works have investigated dimer models that swim reciprocally at intermediate Reynolds numbers Re ~ 1-1000. These show interesting results (e.g. switches of the swim direction as a function of inertia) but the results vary and seem to be case-specific. Here, we introduce a general model and investigate the behaviour of an asymmetric spherical dimer of oscillating length for small-amplitude motion at intermediate Re. In our analysis we make the important distinction between particle and fluid inertia, both of which need to be considered separately. We asymptotically expand the Navier-Stokes equations in the small amplitude limit to obtain a system of linear PDEs. Using a combination of numerical (Finite Element) and analytical (reciprocal theorem, method of reflections) methods we solve the system to obtain the dimer's swim speed and show that there are two mechanisms that give rise to motion: boundary conditions (an effective slip velocity) and Reynolds stresses. Each mechanism is driven by two classes of sphere-sphere interactions, between one sphere's motion and 1) the oscillating background flow induced by the other's motion, and 2) a geometric asymmetry induced by the other's presence. We can thus unify and explain behaviours observed in other works. Our results show how sensitive, counter-intuitive and rich motility is in the parameter space of finite inertia of particles and fluid.Nicholas J. Derr and Thomas Dombrowski and Chris H.

https://scholar.archive.org/work/bfgh7jh37vdr7he7j4og2zrbea
The Fabbri-Russo model is a generalized model of a two-dimensional dilaton gravity theory with various parameters "n" describing various specific gravities. Particularly, the Russo-Susskind-Thorlacius gravity model fits the case n=1. In the Fabbri-Russo model, we investigate Page curves and the entanglement island. Islands are considered in eternal and evaporating black holes. Surprisingly, in any black hole, the emergence of islands causes the rise of the entanglement entropy of the radiation to decelerate after the Page time, satisfying the principle of unitarity. For eternal black holes, the fine-grained entropy reaches a saturation value that is twice the Bekenstein-Hawking entropy. For evaporating black holes, the fine-grained entropy finally reaches zero. The parameter "n" significantly impacts the Page curve at extremely early times. However, at late times and large distance limit, the impact of the parameter "n" is a subleading term and is exponentially suppressed. As a result, the shape of Page curves is "n"-independent in the leading order. Furthermore, we discuss the relationship between islands and firewalls. We show that the island is a better candidate than firewalls for encountering the quantum entanglement-monogamy problem. Finally, we briefly review the gravity/ensemble duality as a potential resolution to the state conundrum resulting from the island formula.Ming-Hui Yu, Xian-Hui Gework_bfgh7jh37vdr7he7j4og2zrbeaWed, 03 Aug 2022 00:00:00 GMTMemory as a Topological Structure on a Surface Network
https://scholar.archive.org/work/gcx6efgzfvgdvfw7b4ortgfodi
A special charged surface network with surface spin half particles on it, that can be arranged in topologically inequivalent ways, is introduced. It is shown that action potential-like signals can be generated in the network in response to local surface deformations of a particular kind. Signals generated in this way carry details of the deformation that create them as a form of plasticity that influences the pathways they traverse leaving a topologically stable helical array of spins: a potential memory substrate. The structure is a non transient alignment of surface spins in response to the transient magnetic field generated by the moving charges present in the action potential-like voltage signals generated since particles with spin have magnetic properties. The structure has a natural excitation frequency that may play a role in memory retrieval. Signal generation and memory storage are proposed to depend on the existence of a surface spin structure. We show that such a surface network can capture the intricate topological features of any connectome in the brain. In addition biophysical properties of such a network are examined in order to constrain predictions of how it may function.Siddhartha Senwork_gcx6efgzfvgdvfw7b4ortgfodiWed, 03 Aug 2022 00:00:00 GMTKazakov-Migdal model on the Graph and Ihara Zeta Function
https://scholar.archive.org/work/bnq3oqatezfe7csbimaaxbjbvi
We propose the Kazakov-Migdal model on graphs and show that, when the parameters of this model are appropriately tuned, the partition function is represented by the unitary matrix integral of an extended Ihara zeta function, which has a series expansion by all non-collapsing Wilson loops with their lengths as weights. The partition function of the model is expressed in two different ways according to the order of integration. A specific unitary matrix integral can be performed at any finite N thanks to this duality. We exactly evaluate the partition function of the parameter-tuned Kazakov-Migdal model on an arbitrary graph in the large N limit and show that it is expressed by the infinite product of the Ihara zeta functions of the graph.So Matsuura, Kazutoshi Ohtawork_bnq3oqatezfe7csbimaaxbjbviWed, 03 Aug 2022 00:00:00 GMTSurface defects, flavored modular differential equations and modularity
https://scholar.archive.org/work/dwdz6bldvfh4to7q72o2stef4u
Every 4d 𝒩 = 2 SCFT 𝒯 corresponds to an associated VOA 𝕍(𝒯), which is in general non-rational with a more involved representation theory. Null states in 𝕍(𝒯) can give rise to non-trivial flavored modular differential equations, which must be satisfied by the refined/flavored character of all the 𝕍(𝒯)-modules. Taking some A_1 theories 𝒯_g,n of class-𝒮 as examples, we construct the flavored modular differential equations satisfied by the Schur index. We show that three types of surface defect indices give rise to common solutions to these differential equations, and therefore are sources of 𝕍(𝒯)-module characters. These equations transform almost covariantly under modular transformations, ensuring the presence of logarithmic solutions which may correspond to characters of logarithmic modules.Haocong Zheng, Yiwen Pan, Yufan Wangwork_dwdz6bldvfh4to7q72o2stef4uWed, 03 Aug 2022 00:00:00 GMTDiscrete Chiral Symmetry and Mass Shift in Lattice Hamiltonian Approach to Schwinger Model
https://scholar.archive.org/work/jz7ae45zujgenircjrxmosflxm
We revisit the lattice formulation of the Schwinger model using the Kogut-Susskind Hamiltonian approach with staggered fermions. This model, introduced by Banks et al., contains the mass term m_ lat∑_n (-1)^nχ^†_n χ_n, and setting it to zero is often assumed to provide the lattice regularization of the massless Schwinger model. We instead argue that the relation between the lattice and continuum mass parameters should be taken as m_ lat=m- 1/8 e^2 a. The model with m=0 is shown to possess a discrete chiral symmetry that is generated by the unit lattice translation accompanied by the shift of the θ-angle by π. While the mass shift vanishes as the lattice spacing a approaches zero, we find that including this shift greatly improves the rate of convergence to the continuum limit. We demonstrate the faster convergence using both numerical diagonalizations of finite lattice systems, as well as extrapolations of the lattice strong coupling expansions.Ross Dempsey, Igor R.

https://scholar.archive.org/work/qjvtnv22x5fkznlkywi4v7hqiq
The electrons are an essential particle species in the solar wind. They often exhibit non-equilibrium features in their velocity distribution function. These include temperature anisotropies, tails (kurtosis), and reflectional asymmetries (skewness), which contribute a significant heat flux to the solar wind. If these non-equilibrium features are sufficiently strong, they drive kinetic micro-instabilities. We develop a semi-graphical framework based on the equations of quasi-linear theory to describe electron-driven instabilities in the solar wind. We apply our framework to resonant instabilities driven by temperature anisotropies. These include the electron whistler anisotropy instability and the propagating electron firehose instability. We then describe resonant instabilities driven by reflectional asymmetries in the electron distribution function. These include the electron/ion-acoustic, kinetic Alfvén heat-flux, Langmuir, electron-beam, electron/ion-cyclotron, electron/electron-acoustic, whistler heat-flux, oblique fast-magnetosonic/whistler, lower-hybrid fan, and electron-deficit whistler instability. We briefly comment on non-resonant instabilities driven by electron temperature anisotropies such as the mirror-mode and the non-propagating firehose instability. We conclude our review with a list of open research topics in the field of electron-driven instabilities in the solar wind.Daniel Verscharen, B. D. G. Chandran, E. Boella, J. Halekas, M. E.

https://scholar.archive.org/work/xfz4ijugs5cyzdp2lareg4qm5i
Optically-levitated dielectric particles can serve as ultra-sensitive detectors of feeble forces and torques, as tools for use in quantum information science, and as a testbed for quantum coherence in macroscopic systems. Knowledge of the structural and optical properties of the particles is important for calibrating the sensitivity of such experiments. Here we report the results of nanomechanical testing of silica nanospheres and investigate an annealing approach which can produce closer to bulk-like behavior in the samples in terms of their elastic moduli. These results, combined with our experimental investigations of optical trap lifetimes in high vacuum at high trapping-laser intensity for both annealed and as-grown nanospheres, were used to provide a theoretical analysis of the effects of porosity and non-sphericity in the samples, identifying possible mechanisms of trapping instabilities for nanospheres with non-bulk-silica-like properties.Cayla R.

https://scholar.archive.org/work/ufxbwnym35adnjoqennrxomm7m
In this paper we study Cheeger deformations on S^3, SO(3) principal bundles to obtain conditions to the existence of submersion metrics of positive sectional curvature on these. We conclude, in particular, a stronger version of the Petersen–Wilhelm fiber dimension conjecture to the class of principal bundles. We prove: any π :SO(3), S^3 ↪ P → B principal bundle over a positively curved base admits a metric of positive sectional curvature if, and only if, the submersion is fat, in particular, B ≥ 4. The proof is done combining the concept of "good triples" due to Munteanu and Tapp , with a Chaves–Derdzisnki–Rigas type condition to non-negative curvature. Additionally, the conjecture is verified for other classes of submersions.Leonardo F. Cavenaghi, Lino Grama, Llohann D.

https://scholar.archive.org/work/a7tymapltnar7gj7lbp7qkosji
We reconsider the complete solution of the linear TBA equation describing the energy density of finite density states in the O(N) nonlinear sigma models by the Wiener-Hopf method. We keep all perturbative and non-perturbative contributions and introduce a running coupling in terms of which all asymptotic series appearing in the problem can be represented as pure power series without logs. We work out the first non-perturbative contribution in the O(3) case and show that (presumably because of the instanton corrections) resurgence theory fails in this example. Using the relation of the O(3) problem to the coaxial disks capacitor problem we work out the leading non-perturbative terms for the latter and show that (at least to this order) resurgence theory, in particular the median resummation prescription, gives the correct answer. We demonstrate this by comparing the Wiener-Hopf results to the high precision numerical solution of the original integral equation.Zoltan Bajnok, Janos Balog, Arpad Hegedus, Istvan Vonawork_a7tymapltnar7gj7lbp7qkosjiWed, 03 Aug 2022 00:00:00 GMTNeutrinos and their interactions with matter
https://scholar.archive.org/work/zmfdcvwljzaiffn7votpgfdxga
We have presented a review of the properties of neutrinos and their interactions with matter. The different (anti)neutrino processes like the quasielastic scattering, inelastic production of mesons and hyperons, and the deep inelastic scattering from the free nucleons are discussed and the results for the scattering cross sections are presented. The polarization observables for the leptons and hadrons produced in the final state, in the case of quasielastic scattering, are also studied. The importance of nuclear medium effects in the low, intermediate and high energy regions, in the above processes along with the processes of the coherent neutrino-nucleus scattering, coherent meson production, and trident production, have been highlighted. In some cases the results of the cross sections are also given and compared with the available experimental data as well as with the predictions in the different theoretical models. This study would be helpful in understanding the (anti)neutrino interaction cross section with matter in the few GeV energy region relevant to the next generation experiments like DUNE, Hyper-Kamiokande, and other experiments with accelerator and atmospheric neutrinos. We have emphasized the need of better theoretical models for some of these processes for studying the nuclear medium effects in nuclei.M. Sajjad Athar, A. Fatima, S. K.

https://scholar.archive.org/work/ws2cq7jtifej3m7axnaz5dbf2m
In this study, a novel approach was investigated to improve the stability of anthocyanin compounds (AC) by encapsulating them in nanoliposomes resulting from rapeseed lecithin alongside chitosan coating. The results indicate that the particle size, electrophoretic mobility, encapsulation efficiency, and membrane fluidity of nanoliposomes containing anthocyanin compounds were 132.41 nm, −3.26 µm·cm/V·S, 42.57%, and 3.41, respectively, which changed into 188.95 nm, +4.80 µm·cm/V·S, 61.15%, and 2.39 after coating with chitosan, respectively. The results also suggest improved physical and chemical stability of nanoliposomes after coating with chitosan. TEM images demonstrate the produced particles were spherical and had a nanoscale, where the existence of a chitosan layer around the nanoparticles was visible. Shear rheological tests illustrate that the flow behavior of nanoliposomes was altered from Newtonian to shear thinning following chitosan incorporation. Further, chitosan diminished the surface area of the hysteresis loop (thixotropic behavior). The oscillatory rheological tests also show the presence of chitosan led to the improved mechanical stability of nanoliposomes. The results of the present study demonstrate that chitosan coating remarkably improved encapsulation efficiency, as well as the physical and mechanical stability of nanoliposomes. Thus, coating AC-nanoliposomes with chitosan is a promising approach for effective loading of AC and enhancing their stability to apply in the pharmaceutic and food industries.Mina Homayoonfal, Mohammad Mousavi, Hossein Kiani, Gholamreza Askari, Stephane Desobry, Elmira Arab-Tehranywork_ws2cq7jtifej3m7axnaz5dbf2mWed, 03 Aug 2022 00:00:00 GMTHomological stability for Iwahori-Hecke algebras

We show that the Iwahori-Hecke algebras H_n of type A_n-1 satisfy homological stability, where homology is interpreted as an appropriate Tor group. Our result precisely recovers Nakaoka's homological stability result for the symmetric groups in the case that the defining parameter is equal to 1. We believe that this paper, and our joint work with Boyd on Temperley-Lieb algebras, are the first time that the techniques of homological stability have been applied to algebras that are not group algebras.Richard Hepworthwork_ltbs33atbbaxtnrbxt644mdyxqWed, 03 Aug 2022 00:00:00 GMTContact and friction simulation for computer graphics
https://scholar.archive.org/work/a46z76uy3bawzjnjqbvigs372u
Efficient simulation of contact is of interest for numerous physics-based animation applications. For instance, virtual reality training, video games, rapid digital prototyping, and robotics simulation are all examples of applications that involve contact modeling and simulation. However, despite its extensive use in modern computer graphics, contact simulation remains one of the most challenging problems in physics-based animation. This course covers fundamental topics on the nature of contact modeling and simulation for computer graphics. Specifically, we provide mathematical details about formulating contact as a complementarity problem in rigid body and soft body animations. We briefly cover several approaches for contact generation using discrete collision detection. Then, we present a range of numerical techniques for solving the associated LCPs and NCPs. The advantages and disadvantages of each technique are further discussed in a practical manner, and best practices for implementation are discussed. Finally, we conclude the course with several advanced topics such as methods for soft body contact problems, barrier functions, and anisotropic friction modeling. Programming examples are provided in our appendix as well as on the course website to accompany the course notes.Sheldon Andrews, Kenny Erleben, Zachary Fergusonwork_a46z76uy3bawzjnjqbvigs372uTue, 02 Aug 2022 00:00:00 GMTQuantum Field Theory Anomalies in Condensed Matter Physics

We give a pedagogical introduction to quantum anomalies, how they are calculated using various methods, and why they are important in condensed matter theory. We discuss axial, chiral, and gravitational anomalies as well as global anomalies. We illustrate the theory with examples such as quantum Hall liquids, Fermi liquids, Weyl semi-metals, topological insulators and topological superconductors. The required background is basic knowledge of quantum field theory, including fermions and gauge fields, and some familiarity with path integral and functional methods.
