Study of WH production through vector boson scattering and extraction of the relative sign of the W and Z couplings to the Higgs boson in proton-proton collisions at $\sqrt{s}$ = 13 TeV

description: A search for the production of a W boson and a Higgs boson through vector boson scattering (VBS) is presented, using CMS data from proton-proton collisions at $\sqrt{s}$ = 13 TeV collected from 2016 to 2018. The integrated luminosity of the data sample is 138 fb$^{-1}$. Selected events must be consistent with the presence of two jets originating from VBS, the leptonic decay of the W boson to an electron or muon, possibly also through an intermediate $τ$ lepton, and a Higgs boson decaying into a pair of b quarks, reconstructed as either a single merged jet or two resolved jets. A measurement of the process as predicted by the standard model (SM) is performed alongside a study of beyond-the-SM (BSM) scenarios. The SM analysis sets an observed (expected) 95% confidence level upper limit of 14.3 (9.9) on the ratio of the measured VBS WH cross section to that expected by the SM. The BSM analysis, conducted within the so-called $κ$ framework, excludes all scenarios with $λ_\mathrm{WZ}$ $\lt$ 0 that are consistent with current measurements, where $λ_\mathrm{WZ}$ = $κ_\mathrm{W} / κ_\mathrm{Z}$ and $κ_\mathrm{W}$ and $κ_\mathrm{Z}$ are the HWW and HZZ coupling modifiers, respectively. The signficance of the exclusion is beyond 5 standard deviations, and it is consistent with the SM expectation of $λ_\mathrm{WZ}$ = 1.

description: For χ 5 (2, .) and χ 5 (3, .) non self-dual L-functions, three types of self-similarity exhibited on the line S=1+i*T are examined in the range (10 5 < T < 10 30 ) linked to (i) large diophantine peaks, and points known to correspond to (ii) large Riemann Zeta function peaks and (iii) large diophantine peaks of the paired dual L-function. The self-similarity for their Davenport-Heilbronn counterparts is also studied and useful approximations for the magnitude of the mescoscale behaviour includes the use of the self-dual χ 5 (4, .) and ζ(s) functions. These mesoscale structure approximations also build a first order version of the distribution of non-trivial zeroes off the critical line for the Davenport-Heilbronn functions.

description: We show that, in presence of isometries and non-trivial topology, the Einstein--Hilbert action is invariant under certain transformations of the metric which are not diffeomorphisms. These transformations are similar to the higher-form symmetries of field theories with $p$-form fields. In the context of toroidal Kaluza--Klein compactifications, we show that these symmetries give rise to some of the ``hidden symmetries'' (dualities) of the dimensionally-reduced theories.

The effects of thermodynamic stability on wind properties in different low mass black hole binary states

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present a systematic theory-motivated study of the thermodynamic stability condition as an explanation for the observed accretion disk wind signatures in different states of low mass black hole binaries (BHB). The variability in observed ions is conventionally explained either by variations in the driving mechanisms or the changes in the ionizing flux or due to density effects, whilst thermodynamic stability considerations have been largely ignored. It would appear that the observability of particular ions in different BHB states can be accounted for through simple thermodynamic considerations in the static limit. Our calculations predict that in the disk dominated soft thermal and intermediate states, the wind should be thermodynamically stable and hence observable. On the other hand, in the powerlaw dominated spectrally hard state the wind is found to be thermodynamically unstable for a certain range of 3.55 <= log ξ<= 4.20. In the spectrally hard state, a large number of the He-like and H-like ions (including e.g. Fe XXV, Ar XVIII and S XV) have peak ion fractions in the unstable ionization parameter (ξ) range, making these ions undetectable. Our theoretical predictions have clear corroboration in the literature reporting differences in wind ion observability as the BHBs transition through the accretion states Lee et al. 2002; Miller et al. 2008; Neilsen & Lee 2009; Blum et al. 2010; Ponti et al. 2012; Neilsen & Homan 2012). While this effect may not be the only one responsible for the observed gradient in the wind properties as a function of the accretion state in BHBs, it is clear that its inclusion in the calculations is crucial to understanding the link between the environment of the compact object and its accretion processes.

description: We demonstrate how the non-trivial interplay between spin-orbit coupling and nodeless $s$-wave superconductivity can drive a fully gapped two-band topological insulator into a time-reversal invariant gapless topological superconductor supporting symmetry-protected Majorana flat bands. We characterize topological phase diagrams by a ${\mathbb Z}_2 \times{\mathbb Z}_2$ partial Berry-phase invariant, and show that, despite the trivial crystal geometry, no unique bulk-boundary correspondence exists. We trace this behavior to the anisotropic quasiparticle bulk gap closing, linear vs. quadratic, and argue that this provides a unifying principle for gapless topological superconductivity. Experimental implications for tunneling conductance measurements are addressed, relevant for lead chalcogenide materials.

description: Previous studies conclusively show that pencil-and-paper lecture-tutorials (LTs) are incredibly effective at increasing student engagement and learning gains on a variety of topics when compared to traditional lecture. LTs in astronomy are post-lecture activities developed with the intention of helping students engage with conceptual and reasoning difficulties around a specific topic with the end goal of them developing a more expert-like understanding of astrophysical concepts. To date, all astronomy LTs have been developed for undergraduate courses taught in-person. Increases in online course enrollments and the COVID-19 pandemic further highlighted the need for additional interactive, research-based, curricular materials designed for online classrooms. To this end, we developed and assessed the efficacy of an innovative, interactive LT designed to teach planet formation in asynchronous, online, introductory astronomy courses for undergraduates. We utilized the Planet Formation Concept Inventory to compare learning outcomes between courses that implemented the new online, interactive LT, and those that used either a lecture-only approach or utilized a standard pencil-and-paper LT on the same topic. Overall, learning gains from the standard pencil-and-paper LT were statistically indistinguishable from the in-person implementation of the online LT and both of these conditions outperformed the lecture-only condition. However, when implemented asynchronously, learning gains from the online LT were lower and not significantly above the lecture-only condition. While improvements can be made to improve the online LT in the future, the current discipline ideas still outperform traditional lecture, and can be used as a tool to teach planet formation effectively.

The Extension Of The Right Of Self-Determination In The Post-Cold War Era
Creators: name: Mustafa, Blerim
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: The present thesis assesses the extent to which the right of self-determination entails a right to remedial secession in the post-Cold War era. Through the prism of the remedial right doctrine, it explores how and under what conditions cases of remedial secession have brought about a change in the perception among the international community regarding the progressive development of remedial secession as a viable norm to help settle post-Cold War contentious self-determination disputes. In light of the case-studies’ – Timor-Leste, Kosovo and Iraqi Kurdistan – precedent-setting impact, post-Cold War state practice demonstrates greater flexibility in accommodating secessionist claims and a limited right to remedial self-determination. Regardless of the merits of a particular case, the right to remedial secession is not self-executing, and the realisation of this mode of external self-determination is contingent on favourable international political constellations. Henceforth, there is a greater likelihood of a favourable secessionist outcome, once the host state is persuaded by a consensus of the international community, to give its political consent to such an outcome. From this standpoint, an act of secession without the consent of the host state, although legitimate from the perspective of remedial secession, is not yet considered as a sustainable and viable mode of settling contentious self-determination disputes, since the sources of continued conflict are still present, and a danger of armed conflict cannot be excluded. In conclusion, the thesis suggests that the applicability of remedial right norms to address post-Cold War secessionist disputes are conditioned by the political support provided by external powerful states to seceding-aspiring entities. Thus, the viability and applicability of remedial right secession as a universal norm to settle contentious secessionist conflicts continue to depend on the perceptions of justice and political viability by the international community and involved parties.

Chiral Perturbation Theory for All-Staggered Heavy-Light Mesons

Year: 2013
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: In highly improved staggered quark (HISQ) simulations by the HPQCD, MILC, and Fermilab Lattice collaborations, both the light quarks and the charm quark are staggered. We extend chiral perturbation theory for staggered quarks to include such all-staggered heavy-light mesons. We assume that the heavy quark action is sufficiently improved that we may take $a m_Q <<1$ (where $m_Q$ is the heavy quark mass), but also that $m_Q>>Λ_{QCD}$ so that a continuum heavy quark expansion is appropriate. We develop this effective chiral theory through next-to-leading order, and use it to study the pattern of taste splittings in the heavy-light meson and to compute the leptonic decay constant of the heavy-light meson to one-loop in the chiral expansion.

description: The interplay between topology, dissipation and nonlinearities can give rise to a wealth of new phenomena and pave the way for novel topological lasers, sensors and other quantum devices. Along these lines, we propose here an optomechanical setup in which the concomitant presence of a spatially modulated external drive and dissipation gives rise to a topologically nontrivial state for mechanical and optical excitations. We are able to show that the one-dimensional system considered here exhibits topologically protected end states for which mechanical and optical degrees of freedom are entangled. We show such entanglement to be robust with respect to the presence of nonzero-temperature baths and we propose a protocol for experimental observation of the entanglement.

description: Most work on social identity, defined as one’s sense of self derived from membership to social groups, focuses on a single identity and its behavioural consequences. But a central insight of social identity theory is that people belong to multiple social groups, derive self-esteem from multiple identities and care to conform to the norms for those identities. However, very little work has turned its attention to understanding when and how multiple social identities interact. We motivate hypotheses with a framework that extends a social identity model to include multiple identities. Using a longitudinal sample (N > 600) of university students located throughout the US, we use university social identity, and the associated university norms, to characterize COVID related social distancing norms between April and October of 2020 and then unpack how another identity, the student’s political identity, impacts perception of those norms. Despite incentives to do otherwise, we find that beliefs about university norms differ depending on the respondent’s political identity. We relate our results back to a model of social identity. Significance Statement: During the wake of the COVID-19 pandemic, norms surrounding precautionary behavior, i.e. hand washing, mask wearing, and so on, quickly emerged and subsequently became highly politicized. In this study, we find evidence that political identity affects one’s ability to perceive university-level norms even when there are incentives in place to focus on those norms and when there are, through government enforced restrictions, forces coordinating behaviour. These results suggest that one’s identities may impact each other, such that one identity obscures an actor’s ability to accurately perceive the norms of another identity, even when there are salient incentives for accurate judgment.

description: The energy spectrum, atom-dimer scattering length, and atom-trimer scattering length for systems of three and four ultracold atoms with $δ$-function interactions in one dimension are presented as a function of the relative mass ratio of the interacting atoms. The Born-Oppenheimer approach is used to treat three-body ("HHL") systems of one light and two heavy atoms, as well as four-body ("HHHL") systems of one light and three heavy atoms. Zero-range interactions of arbitrary strength are assumed between different atoms, but the heavy atoms are assumed to be noninteracting among themselves. Both fermionic and bosonic heavy atoms are considered.

description: In CrX$_2$ (X=Br, I), a Jahn-Teller effect distorts the octahedral configuration of the anions about Cr, resulting in a "ribbon chain" structure. We previously observed helimagnetism in CrI$_2$ propagating along the ribbon chains, with an 80-90$^{\circ}$ rotation per Cr ion. Via neutron scattering, we report that CrBr$_2$ and the solid solution CrIBr are also helimagnetic, with Néel temperatures of 17 and 12 K, respectively, and signs of intermediate magnetic transitions in both compounds. The helical angle between spins on consecutive Cr ions along the ribbon chains increases with increasing Br substitution, from 89.7$^{\circ}$ (CrI$_2$) to 116$^{\circ}$ (CrIBr) to 147$^{\circ}$ (CrBr$_2$), possibly as a result of decreasing longer-range intrachain spin interactions with the increased electron localization of the lighter anions.

Using these observations we determined the rotational rates of the asteroids, with the exception of Nikulin and Renemichelsen. The distribution of rotational rates of 59 V-type asteroids in the inner main belt, including 29 members of the Vesta family that are regarded as ejecta from the asteroid (4) Vesta, is inconsistent with the best-fit Maxwellian distribution. This inconsistency may be due to the effect of thermal radiation Yarkovsky--O'Keefe--Radzievskii--Paddack (YORP) torques, and implies that the collision event that formed V-type asteroids is sub-billion to several billion years in age.

description: Based on the slopes between DESI $g,r$ and IRAS 100 $μm$ intensities, specifically $k_{g}$ and $k_{r}$, we have constructed a substantial sample of Galactic cirri. This sample covers 561.25 deg$^2$ at high Galactic latitudes (|b| $\geq$ 30$^{\circ}$), allowing for a systematic study of the physical parameters of the Galactic cirrus on a large scale, such as $g-r$ color, dust temperature, asymmetry factor and albedo. The ratio of $k_{g}$ and $k_{r}$ is consistent with the diffuse Galactic starlight model, suggesting that the diffuse starlight within our own Galaxy serves as the primary illumination source for the cirrus. Both $k_{g}$ and $k_{r}$ decrease slowly with increasing Galactic latitudes and IRAS 100 $μm$ intensities, while they do not have a correlation with Galactic longitudes. The distribution of $k_{g}$ and $k_{r}$ confirms a significant scatter in the slopes, reaching a factor of 4-5. Such large scatter cannot be explained by the weak correlation between the slopes and Galactic latitudes and IRAS 100 $μm$ intensities. Instead, it is attributed to substantial variations in the intrinsic properties of the dust, e.g., asymmetry factor and albedo. We propose that the properties of dust particles play a critical role in the observed scatter in slopes, making them the primary contributing factors. Moreover, the variations in dust properties within the cirrus are localized rather than exhibiting large-scale gradients.

description: We study the non-linear spherical "top hat" collapse for Chaplygin and viscous unified cosmologies. The term unified refers to models where dark energy and dark matter are replaced by one single component. For the generalized Chaplygin gas (GCG) we extend previous results of [R. A. A. Fernandes {\it et al}. Physical Review D 85, 083501 (2012)]. We discuss the differences at non-linear level between the GCG with $α=0$ and the $Λ$CDM model. We show that both are indeed different. The bulk viscous model which differs from the GCG due to the existence of non-adiabatic perturbations is also studied. In this case, the clustering process is in general suppressed and the viable parameter space of the viscous model that accelerates the background expansion does not lead to collapsed structures. This result challenges the viability of unified viscous models.

description: In this article, we consider the $4+n$ dimensional spacetimes among which one is the four dimensional physical Universe and the other is an n-dimensional sphere with constant radius in the framework of Lanczos-Lovelock gravity. We find that the curvature of extra dimensional sphere contributes a huge but negative energy density provided that its radius is sufficiently small, such as the scale of Planck length. Therefore, the huge positive vacuum energy, i.e. the large positive cosmological constant is exactly cancelled out by the curvature of extra sphere. In the mean time the higher order of Lanczos-Lovelock term contributes an observations-allowed small cosmological constant if the number of extra dimensions is sufficiently large, such as $n\approx{69}$.

description: Existing research suggests that people prone to boredom may have high self-directed attention (i.e., the tendency to focus on one’s inner experiences) but low self-knowledge (i.e., the tendency to possess knowledge of one’s inner experiences), which are two distinct aspects of self-perception. We empirically tested this proposal across multiple studies by examining the relationships between indices of boredom, self-directed attention, and self-knowledge. In Studies 1 and 2, we created a measure of state self-directed attention that possesses good psychometric properties, reliability, and convergent and construct validity. Additionally, we tested and confirmed the hypothesis that experimentally manipulating self-directed attention has no significant impact on boredom (Study 1), but that experimentally manipulating boredom causes a significant increase in self-directed attention (Study 2). In Study 3, we tested and confirmed the hypothesis that trait self?directed attention, trait self-knowledge, and trait boredom are correlated, but psychometrically distinct, dispositional constructs. We also tested and confirmed the hypothesis that trait self-directed attention and trait self-knowledge are uniquely associated with trait boredom (Study 3). Implications and future directions related to furthering our understanding of boredom and aspects of self-perception are discussed.

On Landau's Eigenvalue Theorem for Line-of-Sight MIMO Channels
Creators: name: Pizzo, Andrea

subject: FOS: Computer and information sciences

description: An alternative derivation is provided for the degrees of freedom (DOF) formula on line-of-sight (LOS) channels via Landau's eigenvalue theorem for bandlimited signals. Compared to other approaches, Landau's theorem provides a general framework to compute the DOF in arbitrary environments, this framework is herein specialized to LOS propagation. The development shows how the spatially bandlimited nature of the channel relates to its geometry under the paraxial approximation that applies to most LOS settings of interest.

description: We investigate the geometry of the magnetic field towards the Radcliffe Wave, a coherent 3-kpc-long part of the nearby Local Arm recently discovered via three-dimensional dust mapping. We use archival stellar polarization in the optical and new measurements in the near-infrared to trace the magnetic field as projected on the plane of the sky. Our new observations cover the portion of the structure that is closest to the Sun, between Galactic longitudes of 122$^\circ$ and 188$^\circ$. The polarization angles of stars immediately background to the Radcliffe Wave appear to be aligned with the structure as projected on the plane of the sky. The observed magnetic field configuration is inclined with respect to the Galactic disk at an angle of 18$^\circ$. This departure from a geometry parallel to the plane of the Galaxy is contrary to previous constraints from more distant stars and polarized dust emission. We confirm that the polarization angle of stars at larger distances shows a mean orientation parallel to the Galactic disk. We discuss implications of the observed morphology of the magnetic field for models of the large-scale Galactic magnetic field, as well as formation scenarios for the Radcliffe Wave itself.

description: Background: Meningeal melanocytomas (MM) are rare primary melanocytic tumors of the leptomeninges with an incidence of 1:10,000,000. Until now, there has been only sparse information about this tumor entity. Here, we provide a meta-analysis of all cases published in the English language since 1972. Methods: A literature review was performed using PubMed and Web of Science. All published cases were evaluated for location, sex, age, therapeutic approach, and outcome. In total, we included 201 patient cases in our meta–analysis. Results: The majority of MM was diagnosed more frequently in men between the third and fifth decade of life. Surgery is the preferred therapeutic approach, and total resection is associated with the best outcome. Patients with partial resection or tumor recurrence benefit from adjuvant radiotherapy, whereas chemo- or immunotherapies do not improve the disease course. Malignant transformation was described in 18 patients. Of these, 11 patients developed metastasis. Conclusions: We present the first retrospective meta-analysis of all MM cases published in the English language, including an evaluation of different treatment strategies allowing us to suggest a novel treatment guideline highlighting the importance of total resection for recurrence–free survival and characterizing those cases which benefit from adjuvant radiotherapy.

description: Semantic communication, notable for ensuring quality of service by jointly optimizing source and channel coding, effectively extracts data semantics, reduces transmission length, and mitigates channel noise. However, most studies overlook multi-user scenarios and resource availability, limiting real-world application. This paper addresses this gap by focusing on downlink communication from a base station to multiple users with varying computing capacities. Users employ variants of Swin transformer models for source decoding and a simple architecture for channel decoding. We propose a novel training regimen, incorporating transfer learning and knowledge distillation to improve low-computing users' performance. Extensive simulations validate the proposed methods.

Control of Microparticles Through Hydrodynamic Interactions

description: The controllability of passive microparticles that are advected with the fluid flow generated by an actively controlled one is studied. The particles are assumed to be suspended in a viscous fluid and well separated so that the far-field Stokes flow solutions may be used to describe their interactions. Applying concepts from geometric control theory, explicit moves characterized by a small amplitude parameter $\varepsilon$ are devised to prove that the active particle can control one or two passive particles. The leading-order (in $\varepsilon$) theoretical predictions of the particle displacements are compared with those obtained numerically and it is found that the discrepancy is small even when $\varepsilon\approx 1$. These results demonstrate the potential for a single actuated particle to perform complex micromanipulations of passive particles in a suspension.

Solubility of Natural Gas in Various Crude Oils and Preparation of Pure Methane from Natural Gas
Creators: name: Kircher, Charles Edmund Jr.
Publisher: name: California Institute of Technology
Year: 1933
Subjects: subject: Chemical Engineering
subject: FOS: Chemical engineering

description: The work reported in this paper is a continuation of experiments begun and carried out by B.H. Sage, and described in his thesis for the Masters degree C.I.T. 1931. The object of the research was to determine as quantitatively as possible the solubility of natural gas in various crude oils, as it was known that by dissolving natural gas in crude oil, the physical properties of the oil could be changed in such a way as to make possible greater recovery of the crude oil from the underground formation. As pointed out by Mr. Sage, the solubility figures presented in his thesis had to be arrived
at by a method of approximation as he was then not experimentally able to measure the change in liquid volume resulting from dissolved gas. In order to make possible more accurate calculation of gas solubility, apparatus was designed and installed for directly measuring the change in volume of the crude oil which occurred as a result of dissolved gas. Other changes were made in the equipment as first set up by Mr. Sage, which were designed to increase accuracy and speed in carrying out the experiments. These changes will be discussed in the main body of this report.
Finding Approximate Pythagorean Triples (and Applications to LEGO Robot Building)

description: This assignment combines programming and data analysis to determine good combinations of side lengths that approximately satisfy the Pythagorean Theorem for right triangles. This can be a standalone exercise using a wide variety of programming languages, but the results are useful for determining good ways to assemble LEGO pieces in robot construction, so the exercise can serve to integrate three different units of the Exploring Computer Science high school curriculum [3]: "Programming", "Computing and Data Analysis", and "Robotics". Sample assignment handouts are provided for both Scratch and Java programmers. Ideas for several variants of the assignment are also provided.

description: The Discrete Gabor Transform (DGT) is the most commonly used transform for signal analysis and synthesis using a linear frequency scale. It turns out that the involved operators are rich in structure if one samples the discrete phase space on a subgroup. Most of the literature focuses on separable subgroups, in this paper we will survey existing methods for a generalization to arbitrary groups, as well as present an improvement on existing methods. Comparisons are made with respect to the computational complexity, and the running time of optimized implementations in the C programming language. The new algorithms have the lowest known computational complexity for nonseparable lattices and the implementations are freely available for download. By summarizing general background information on the state of the art, this article can also be seen as a research survey, sharing with the readers experience in the numerical work in Gabor analysis.

Cyclicity of the shift operator through Bezout identities

Publisher: name: arXiv

Subjects: subject: Complex Variables (math.CV)

description: In this paper, we study the cyclicity of the shift operator $S$ acting on a Banach space $\X$ of analytic functions on the open unit disc $\D$. We develop a general framework where a method based on a corona theorem can be used to show that if $f,g\in\X$ satisfy $|g(z)|\leq |f(z)|$, for every $z\in\D$, and if $g$ is cyclic, then $f$ is cyclic. We also give sufficient conditions for cyclicity in this context. This enable us to recapture some recent results obtained in de Branges-Rovnayk spaces, in Besov--Dirichlet spaces and in weighted Dirichlet type spaces.

description: We propose a classical action for the motion of massless Weyl fermions in a background gauge field in (2N+1)+1 spacetime dimensions. We use this action to derive the collisionless Boltzmann equation for a gas of such particles, and show how classical versions of the gauge and Abelian chiral anomalies arise from the Chern character of the non-Abelian Berry connection that parallel transports the spin degree of freedom in momentum space.
