description: We present a cosmographic study designed to test the simplest type of accelerating cosmology: a flat universe with matter and a cosmological constant ($Λ$). Hubble series expansions are fit to the SCP Union2.1 supernova data set to estimate the Hubble Constant ($H_{0}$), the deceleration parameter ($q_{0}$), and the jerk parameter ($j_{0}$). Flat $Λ$CDM models always require $j_{0} = 1$, providing a single-parameter test of the entire paradigm. Because of convergence issues for $z \gtrsim 1$, we focus on expansions using the newer redshift variable $y$, and to estimate the effects of "model-building uncertainties" -- the dependence of the output results upon the fitting function and parameters used -- we perform fits using five different distance indicator functions, and four different polynomial orders. We find that one cannot yet use the supernova data to reliably obtain more than four cosmological parameters, and that cosmographic estimates of $j_{0}$ remain dominated by model-building uncertainties, in conjunction with statistical and other error sources. While $j_{0} = 1$ remains consistent with Union2.1, the most restrictive bound that we can place is $j_{0} \sim [-7.6,8.5]$. To test the future prospects of cosmography with new standard candle data, ensembles of mock supernova data sets are created, and it is found that the best way to reduce model-building uncertainties on lower-order Hubble parameters (such as $\{H_{0}, q_{0}, j_{0} \}$) is by limiting the redshift range of the data. Thus more and better $z \lesssim 1$ data, not higher-redshift data, is needed to sharpen cosmographic tests of flat $Λ$CDM.

description: The Turin Declaration on Humanitarian Forensic Odontology was signed during the Panel Discussion of the 2nd AFOHR Biennial Symposium on the 14th of October 2023, by all contributors. This document will serve as a framework to guide the practice, development, and advancement of humanitarian forensic odontology (HFO). HFO refers to the application of forensic odontology principles, practices, and techniques leading to the best practices in human identification and age estimation through the humanitarian approach which comprises humanity, neutrality, impartiality, and independence.
HFO is used in various scenarios like mass disasters, armed conflicts, terrorist attacks, human trafficking, and abuse cases. Its action includes recognizing, gathering, examining, interpreting, reporting, and presenting (in a court of law) dental evidence to help identify victims of any age spectrum, document human rights abuses, and offer proof for legal proceedings. HFO also aims to bring closure to affected families while respecting their right to obtain information about loved ones and contribute to justice through comprehensive assessments involving multiple disciplines.

description: We consider the effect on LHC jet cross sections on partons distribution functions (PDFs), in particular the MSTW2008 set of PDFs. We first compare the published inclusive jet data to the predictions using MSTW2008, finding a very good description. We also use the parton distribution reweighting procedure to estimate the impact of these new data on the PDFs, finding that the combined ATLAS 2.76 TeV and 7 TeV data, and CMS 7 TeV data have some significant impact. We then also investigate the impact of ATLAS, CMS and D0 dijet data using the same techniques. In this case we investigate the effect of using different scale choices for the NLO cross section calculation. We find that the dijet data is generally not completely compatible with the corresponding inclusive jet data, often tending to pull PDFs, particularly the gluon distribution, away from the default values. However, the effect depends on the dijet data set used as well as the scale choice. We also note that conclusions may be affected by limiting the pull on the data luminosity chosen by the best fit, which is sometimes a number of standard deviations. Finally we include the inclusive jet data in a new PDF fit explicitly. This enables us to check the consistency of the exact result with that obtained from the reweighting procedure. There is generally good, but not full quantitative agreement. Hence, the conclusion remains that MSTW2008 PDFs already fit the published jet data well, but the central values and uncertainties are altered and improved respectively by significant, but not dramatic extent by inclusion of these data.

description: Why do people decide to engage in certain activities and not others? A new, integrative 2x2 framework of goal pursuit activities provides novel insight into the kinds of truth- and control-oriented activities within the process of goal pursuit that are motivationally relevant to people with a prevention versus promotion focus (Nakkawita & Higgins, 2021). The present research utilizes these different types of goal pursuit activities to investigate whether motivational relevance contributes to differences in activity decision making. In this study, after measuring participants' motivational orientations, we will present them with opportunities to decide to engage in activities involving differing degrees of motivational relevance to these motives. We hypothesize that participants will tend to choose to engage in activities that are more (vs. less) motivationally relevant.

description: It is assumed that education is an instrument for bringing out the potentialities of human beings while effectiveness of a education system is mainly dependent upon its teachers. Teaching is an art and the quality of teaching depends on the love, dedication and devotion of the teacher towards the subject of the knowledge. The quality of any teaching programme cannot rise above the quality of its teachers. In the professional preparation of teachers, the study of attitudes held by them is very important. The attitude of teacher is a teacher's characteristic and component of teacher's personality. How a teacher performs his duty as a teacher is dependent, to a great extent, on his attitudes values and beliefs. A positive favourable attitude makes the work not only easier but also more satisfying and professionally rewarding; rather a negative attitude makes the teaching task harder, more tedious and unpleasant. Self-efficacy belief is of paramount importance in the transfer of the information and skills that prospective teachers acquire during their prospective education to the students. Mental health is a concept that refers to individual emotional and psychological well-being. Feeling capable and competent; being able to handle normal level of stress, and lead an independent life; and being able to "bounce back" or recover from difficult situations, are all signs of mental health. The researcher used survey method for present study. The population of the present study was all the B.Ed. Trainees of Patna. Random sampling technique was used to select 400 prospective teachers studying in 8 B.Ed. Colleges run by government and private management in Patna town. . There is no significant correlation between attitude and self – efficacy of teacher trainees while there is significant correlation between attitude and mental health & self – efficacy and mental health of teacher trainees.

description: Cellular Automata are discrete-time dynamical systems on a spatially extended discrete space which provide paradigmatic examples of nonlinear phenomena. Their stochastic generalizations, i.e., Probabilistic Cellular Automata (PCA), are discrete time Markov chains on lattice with finite single-cell states whose distinguishing feature is the \emph{parallel} character of the updating rule. We study the ground states of the Hamiltonian and the low-temperature phase diagram of the related Gibbs measure naturally associated with a class of reversible PCA, called the \textit{cross PCA}. In such a model the updating rule of a cell depends indeed only on the status of the five cells forming a cross centered at the original cell itself. In particular, it depends on the value of the center spin (\textit{self-interaction}). The goal of the paper is that of investigating the role played by the self-interaction parameter in connection with the ground states of the Hamiltonian and the low-temperature phase diagram of the Gibbs measure associated with this particular PCA.
Self-Sustained Turbulence without Dynamical Forcing: A Two-Dimensional Study of a Bistable Interstellar Medium

description: In this paper, the nonlinear evolution of a bistable interstellar medium is investigated using two-dimensional simulations with a realistic cooling rate, thermal conduction, and physical viscosity. The calculations are performed using periodic boundary conditions without any external dynamical forcing. As the initial condition, a spatially uniform unstable gas under thermal equilibrium is considered. At the initial stage, the unstable gas quickly segregates into two phases, or cold neutral medium (CNM) and warm neutral medium (WNM). Then, self-sustained turbulence with velocity dispersion of $0.1-0.2\;\mathrm{km\;s^{-1}}$ is observed in which the CNM moves around in the WNM. We find that the interfacial medium (IFM) between the CNM and WNM plays an important role in sustaining the turbulence. The self-sustaining mechanism can be divided into two steps. First, thermal conduction drives fast flows streaming into concave CNM surfaces towards the WNM. The kinetic energy of the fast flows in the IFM is incorporated into that of the CNM through the phase transition. Second, turbulence inside the CNM deforms interfaces and forms other concave CNM surfaces, leading to fast flows in the IFM. This drives the first step again and a cycle is established by which turbulent motions are self-sustained.

description: The central cD galaxy of the Hydra A cluster has one of the most powerful active galactic nuclei (AGNs) in the nearby Universe (z <0.2). We report on the discovery of a dust lane in the cD galaxy using Subaru telescope. The i'-band image shows the existence of a dark band of the size of 3.6"x 0.7" (4 kpc x 0.8 kpc), which appears to be quite similar to the dust lane observed in Centaurus A. The morphology indicates that the cold disk that seen as the dust lane is almost edge-on and rotates around the AGN. Since the minor axis of the dust lane is nearly parallel to the radio jets emerging from the AGN, the disk is probably feeding its gas into the central black hole. From the absorption, we estimate the hydrogen column density of the lane is N_H=2.0 x 10^21 cm^-2, and the mass of the disk is ~8 x 10^7 M_sun. The column density is consistent with constraints obtained from Chandra X-ray observations. The age of the disk is >~ 4 x 10^7 yr. The position angle of the disk and the galaxy's photometric axis are misaligned, which may imply that the cold gas in the disk is brought via galaxy mergers. Our observations may indicate that the supply of cold gas by galaxy mergers is required for the most intensive feedback from AGNs.

description: Reports of emergent conductivity, superconductivity, and magnetism at oxide interfaces have helped to fuel intense interest in their rich physics and technological potential. Here we employ magnetic force microscopy to search for room-temperature magnetism in the well-studied LaAlO3/SrTiO3 system. Using electrical top gating to deplete electrons from the oxide interface, we directly observe an in-plane ferromagnetic phase with sharply defined domain walls. Itinerant electrons, introduced by a top gate, align antiferromagnetically with the magnetization, at first screening and then destabilizing it as the conductive state is reached. Subsequent depletion of electrons results in a new, uncorrelated magnetic pattern. This newfound control over emergent magnetism at the interface between two non-magnetic oxides portends a number of important technological applications.

Classical torus conformal block, N=2* twisted superpotential and the accessory parameter of Lame equation

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this work the correspondence between the semiclassical limit of the DOZZ quantum Liouville theory on the torus and the Nekrasov-Shatashvili limit of the N=2* (Omega-deformed) U(2) super-Yang-Mills theory is used to propose new formulae for the accessory parameter of the Lame equation. This quantity is in particular crucial for solving the problem of uniformization of the one-punctured torus. The computation of the accessory parameters for torus and sphere is an open longstanding problem which can however be solved if one succeeds to derive an expression for the so-called classical Liouville action. The method of calculation of the latter has been proposed some time ago by Zamolodchikov brothers. Studying the semiclassical limit of the four-point function of the quantum Liouville theory on the sphere they have derived the classical action for the Riemann sphere with four punctures. In the present work Zamolodchikovs idea is exploited in the case of the Liouville field theory on the torus. It is found that the Lame accessory parameter is determined by the classical Liouville action on the one-punctured torus or more concretely by the torus classical block evaluated on the saddle point intermediate classical weight. Secondly, as an implication of the aforementioned correspondence it is obtained that the torus accessory parameter is related to the sum of all rescaled column lengths of the so-called "critical" Young diagrams extremizing the instanton "free energy" for the N=2* gauge theory. Finally, it is pointed out that thanks to the known relation the sum over the "critical" column lengths can be expressed in terms of a contour integral in which the integrand is built out of certain special functions.

description: L'utilisation du pouvoir investi à des fins personnelles », la mauvaise gouvernance est devenue aujourd'hui un fardeau multidimensionnel Actuellement, Madagascar est classé aux cent quarante septième rangs mondiaux en termes d'indice de perception de la mauvaise gouvernance. L'objectif de ce manuscrit est d'évaluer les enjeux de la mauvaise gouvernance dans l'employabilité des jeunes diplômés universitaires en Afrique, afin de définir des perspectives pour le cas de Madagascar. Pour réaliser ce travail, 280 personnes ont été enquêté et les données ont été traitées sous le logiciel SPSS. Les résultats ont révélé qu'une grande partie des chômeurs sont des jeunes. 45% de la population étudiée ne savent rien sur les impacts de la mauvaise gouvernance dans l’ensemble. Seulement 38% ont une bonne connaissance sur ce fléau. La quasi-totalité des enquêtés (73%) n’a jamais entendu au moins une action d’information, d’éducation et de communication en matière de la bonne gouvernance ou la lutte contre la mauvaise gouvernance. Une faible proportion a confirmé qu’ils ont déjà entendu (27%). Outre la difficulté du gouvernement à mettre en place une politique de promotion de l'emploi, le chômage s'explique également par le manque de crédibilité des sortants Universitaires. La mauvaise gouvernance durant l’étude est un facteur qui limite la capacité des jeunes diplômés à trouver un emploi. La prolifération de la corruption rend plus complexe la recherche d’emploi des sortants universitaires. Le problème de l'emploi des jeunes n'est pas seulement le reflet du manque d'offre sur le marché du travail, mais aussi de leur capacité technique par rapport à leur diplôme déclaré. Par conséquent, la résolution du problème de l'emploi doit d'abord passer par une bonne gouvernance dans les établissements scolaire.

description: A theorem of Hoffman gives an upper bound on the independence ratio of regular graphs in terms of the minimum $λ_{\min}$ of the spectrum of the adjacency matrix. To complement this result we use random eigenvectors to gain lower bounds in the vertex-transitive case. For example, we prove that the independence ratio of a $3$-regular transitive graph is at least \[q=\frac{1}{2}-\frac{3}{4π}\arccos\biggl(\frac{1-λ_{\min}}{4}\biggr).\] The same bound holds for infinite transitive graphs: we construct factor of i.i.d. independent sets for which the probability that any given vertex is in the set is at least $q-o(1)$. We also show that the set of the distributions of factor of i.i.d. processes is not closed w.r.t. the weak topology provided that the spectrum of the graph is uncountable.

description: Research suggests that public stigma toward people with paedophilia (PWP) and the internalisation of this stigma (i.e., self-stigma) prevent PWP from seeking therapeutic care for their problem prior to offending against children. Fear of rejection, prosecution, or unethical practice by healthcare professionals is a specific barrier. Understanding barriers to secondary child sexual abuse prevention programs for PWP and their implementation in Australia requires investigation of professionals’ stigmatising beliefs, attitudes, and attributions toward this population. This research aims to examine barriers to disclosure, help-seeking, and treatment access for PWP, who may or may not offend, by sampling and examining the stigmatising beliefs and attitudes of Australian criminal justice, social work, and mental health professionals toward PWP. Understanding and developing pragmatic and sensitive approaches to destigmatising disclosure and improving help-seeking by PWP through increasing willingness to treat this population may pose a novel way to prevent sexual abuse of children. The purpose of this interview is to consult with ‘elite’ managing professionals and tertiary educators of practice disciplines likely to work with or around people with paedophilia, to discuss the current training and education provided to professionals and pre-professionals in these fields. We are interested in gaining expert opinion and insights about how professionals and pre-professionals are trained to think about and prepare to potentially engage with people with paedophilia who are seeking help or treatment concerning their sexual attraction. We want to know participants' unique perspective on this issue, and whether they believe their organisational style and discipline’s ethos shapes exposure to this training. Professionals do not have to have had direct experience in treating or referring on offending or non-offending people with paedophilia to contribute your perspective. For the purpose of this interview, paedophilia will be used to describe people who have a dominant sexual interest or attraction to children or adolescents under 18 years of age.

description: We consider a quantum quench of the trap frequency in a system of bosons interacting through an inverse-square potential and confined in a harmonic trap (the harmonic Calogero model). We determine exactly the initial state in terms of the post-quench eigenstates and derive the time evolution of simple physical observables. Since this model possesses an infinite set of integrals of motion (IoM) that allow its exact solution, a generalised Gibbs ensemble (GGE), i.e. a statistical ensemble that takes into account the conservation of all IoM, can be proposed in order to describe the values of local physical observables long after the quench. Even though, due to the presence of the trap, physical observables do not exhibit equilibration but periodic evolution, such a GGE may still describe correctly their time averaged values. We check this analytically for the local boson density and find that the GGE conjecture is indeed valid, in the thermodynamic limit.

description: In 2008 the Cornell Electron/Positron Storage Ring (CESR) was reconfigured from an electron/positron collider to serve as a testbed for the International Linear Collider (ILC) damping rings. One of the primary goals of the CESR Test Accelerator (CesrTA) project is to develop a fast low-emittance tuning method which scales well to large rings such as the ILC damping rings, and routinely achieves a vertical emittance of order 10 pm at 2.085 GeV. This paper discusses the tuning methods developed at CesrTA to achieve low-emittance conditions. One iteration of beam-based measurement and correction requires about 10 minutes. A minimum vertical emittance of 10.3 +3.2/-3.4(sys) +/-0.2(stat) pm has been achieved at 2.085 GeV. In various configurations and beam energies the correction technique routinely achieves vertical emittance around 10 pm after correction, with RMS coupling < 0.5%. The measured vertical dispersion is dominated by beam position monitor systematics. The propagation of uncertainties in the emittance measurement is described in detail. Simulations modeling the effects of magnet misalignments, BPM errors, and emittance correction algorithm suggest the residual vertical emittance measured at the conclusion of the tuning procedure is dominated by sources other than optics errors and misalignments.

description: Generating renewable energy on Mars is technologically challenging. Firstly, because, compared to Earth, key energy resources such as solar and wind are weak as a result of very low atmospheric pressure and low solar irradiation. Secondly, because of the harsh environmental conditions, the required high degree of automation, and the exceptional effort and cost involved in transporting material to the planet. Like on Earth, it is crucial to combine complementary resources for an effective renewable energy solution. In this work, we present the results of a design synthesis exercise, a 10 kW microgrid solution, based on a pumping kite power system and photovoltaic solar modules to power the construction and subsequent use of a Mars habitat. To buffer unavoidable energy fluctuations and balance seasonal and diurnal resource variations, the two energy systems are combined with a compressed gas storage system and lithium-sulphur batteries. The airborne wind energy solution was selected because of its low weight-to-wing-surface-area ratio, compact packing volume, and high capacity factor which enables it to endure strong dust storms in an airborne parking mode. The surface area of the membrane wing is 50 m2 and the mass of the entire system, including the kite control unit and ground station, is 290 kg. The performance of the microgrid was assessed by computational simulation using available resource data for a chosen deployment location on Mars. The projected costs of the system are €8.95 million, excluding transportation to Mars.

description: We analyse the $\overline B_s^0\to K^+l^-\bar ν$ and $\overline B_s^0\to K^{*+}(\to Kπ) \ell^-\bar ν$ decays that are valuable for extracting the CKM matrix element $|V_{ub}|$. We calculate the differential and integrated partial widths in units of $|V_{ub}|^2$ based on various calculations of hadronic form factors and in particular the latest Lattice QCD calculation of the $B_s\to K^*$ form factors. For the decay $\overline B_s^0 \to Kπ\ell\bar ν$, we formulate the general angular distributions with the inclusion of the various partial-wave $Kπ$ contributions. Using the results for the $Kπ$ scalar form factor calculated from unitarized chiral perturbation theory, we explore the S-wave effects on angular distribution variables and demonstrate that they may not be negligible, considering the high precision expected in future measurements. We also briefly discuss the impact of the S-wave $ππ$ contributions in the $B^-\to π^+π^-\ell \bar ν$ decay and provide estimates for the mode $B^-\to K^+K^-\ell \bar ν$. The studies of these channels in future can not only be used to determine $|V_{ub}|$, but may also provide valuable information on the $Kπ$ and $ππ$ phase shifts.

description: Quantity processing is one of the important research issues in the field of quantity cognition. Efficient and accurate quantity processing has the survival significance of evolutionary nature, which is more conducive to human making reasonable decisions. In the field of mathematical cognition, some evidence has been accumulated, indicating that the cognitive representation of number size is closely related to spatial coding. The most direct performance is spatial numeric association of response codes (SNARC) effect, that is, small numbers are associated with the left side of space, and large numbers are associated with the right side of space.There are two theories that can explain this phenomenon: the Mental Number Line and Working Memory account.Their disagreement is whether spatial number association is affected by working memory load. So we want to explore this question in a novel way.

description: The N=20 and N=28 "islands of inversion" are described by large scale shell model calculations with an extension of the interaction sdpf-u that makes it possible to mix configurations with different Nhw or equivalently with different number of particles promoted from the sd-shell to the pf-shell. It allows to connect the classical sd-shell calculations below N=18 with the sd(protons)-pf(neutrons) calculations beyond N=24-26, for all the isotopes from Oxygen to Calcium, using the same interaction. For some isotopes this range contains all the nuclei between the proton and the neutron drip lines and includes the N=20 and N=28 islands of inversion. We shall pay particular attention to the properties of the states at fix Nhw which turn out to be the real protagonists of the physics at N=20. The existence of islands of inversion/deformation will be explained as the result of the competition between the spherical mean field which favors the 0hw configurations and the nuclear correlations which favor the deformed Nhw configurations. The Magnesium chain is exceptional because in it, the N=20 and N=28 "islands of inversion" merge, enclosing all the isotopes between N=19 and N=30. Indeed, this would be also the case for the Neon and Sodium chains if their drip lines would reach N=28.

description: We investigate how two different modalities to construct shared reality can effects its outcomes. Shared reality is the experience of having in common with others inner states about the world. Inner states include the perceived relevance of something, as well as feelings, beliefs, or evaluations of something. The experience of having such inner states in common with others can be affected by how the perception of shared reality has come about. In particular, the consequences of co-creating a shared reality vs finding another person that already holds/beliefs in the reality you share before it is perceived as common. When the same share reality is co-created with the other person as opposed to being just validated by the other person, we believe individuals will report not only higher levels of shared reality but also perceived agreement, responsiveness, similarity, closeness, epistemic co-creation and certainty, more information is shared and the other person is perceived more favorably.
Bounded-Choice Statements for User Interaction in Imperative and Object-Oriented Programming

description: Adding versatile interactions to imperative programming -- C, Java and Android -- is an essential task. Unfortunately, existing languages provide only limited constructs for user interaction. These constructs are usually in the form of $unbounded$ quantification. For example, existing languages can take the keyboard input from the user only via the $read(x)/scan(x)$ construct. Note that the value of $x$ is unbounded in the sense that $x$ can have any value. This construct is thus not useful for applications with bounded inputs. To support bounded choices, we propose new bounded-choice statements for user interation. Each input device (the keyboard, the mouse, the touch, $...$) naturally requires a new bounded-choice statement. To make things simple, however, we focus on a bounded-choice statement for keyboard -- kchoose -- to allow for more controlled and more guided participation from the user. It is straightforward to adjust our idea to other input devices. We illustrate our idea via Java(BI), an extension of the core Java with a new bounded-choice statement for the keyboard.

description: Some peculiar features found in the angular distribution of the cosmic microwave background (CMB) measured by the Wilkinson Microwave Anisotropy Probe (WMAP) deserve further investigation. Among these peculiar features, is the quadrant asymmetry, which is likely related to the north-south asymmetry. In this paper, we aim to extend the analysis of the quadrant asymmetry in the $Λ$CDM framework to the Planck foreground-cleaned maps, using the mask provided by Planck team. We compute the two-point correlation function (TPCF) from each quadrant of the Planck CMB sky maps, and compare the result with 1000 Monte Carlo (MC) simulations generated assuming the $Λ$CDM best-fit power spectrum. We detect the presence of an excess of power in the southeastern quadrant (SEQ) and a significant lack of power in the northeastern quadrant (NEQ) in the Planck data. Asymmetries between the SEQ and the other three quadrants (southwestern quadrant (SWQ), northwestern quadrant (NWQ), and NEQ) are each in disagreement with an isotropic sky at a 95\% confidence level. Furthermore, by rotating the Planck temperature sky map with respect to z direction, we showed the rotation angle where the TPCF of the SEQ has its maximal power. Our analysis of the Planck foreground-cleaned maps shows that there is an excess of power in the TPCF in the SEQ and a significant lack of power in the NEQ when compared with simulations. This asymmetry is anomalous when considering the $Λ$CDM framework .

description: A dispersion integral is derived that connects data on $η\to π^+π^-γ$ to the $η\to γγ^*$ transition form factor. A detailed analysis of the uncertainties is provided. We find for the slope of the $η$ transition form factor at the origin $b_η= (2.05 {}^{+0.22}_{-0.10})\, {\rm GeV}^{-2}$. Using an additional, plausible assumption, one finds for the corresponding slope of the $η'$ transition form factor, $b_{η'} = (1.58 {}^{+0.15}_{-0.08})\, {\rm GeV}^{-2}$. Both values are consistent with all recent data, but differ from some previous theoretical analyses.

description: Occupational characteristics have been studied as risk factors for several age-related diseases and are thought to impact the ageing process, although there has been limited empirical work demonstrating an association between adverse occupational characteristics and accelerated ageing and this prior work has yielded mixed results. We used the 2010 and 2016 waves of the Health and Retirement Study (n = 1,251) to examine the association between occupation categories and self-reported working conditions of American adults at midlife and their subsequent epigenetic ageing as measured through five epigenetic clocks: PCHorvath, PCHannum, PCPhenoAge, PCGrimAge, and DunedinPACE. We found that individuals working in sales/clerical, service, and manual work show evidence of epigenetic age acceleration compared to those working in managerial/professional jobs and that the associations were stronger with second- and third-generation clocks. Individuals reporting high stress and high physical effort at work showed evidence of epigenetic age acceleration only on PCGrimAge and DunedinPACE. Most of these associations were attenuated after adjustment for race/ethnicity, educational attainment, and lifestyle-related risk factors. Sales/clerical work remained significantly associated with PCHorvath and PCHannum, while service work remained significantly associated with PCGrimAge. The results suggest that manual work and occupational physical activity may appear to be risk factors for epigenetic age acceleration through their associations with socioeconomic status, while stress at work may be a risk factor for epigenetic age acceleration through its associations with health behaviours outside of work. Additional work is needed to understand when in the life course and the specific mechanisms through which these associations occur.

description: We study the effects of top-Higgs anomalous coupling in the production of a pair of Higgs boson via gluon fusion at the Large Hadron Collider (LHC). The introduction of anomalous $ttH$ coupling can alter the hadronic double Higgs boson cross section and can lead to characteristic changes in certain kinematic distributions. We perform a global analysis based on available LHC data on the Higgs to constrain the parameters of $ttH$ anomalous coupling. Possible overlap of the predictions due to anomalous $ttH$ coupling with those due to anomalous trilinear Higgs coupling is also studied. We briefly discuss the effect of the anomalous $ttH$ coupling on the $HZ$ production via gluon fusion which is one of the main backgrounds in the $HH \to γγb {\bar b}$ channel.
