The hierarchical formation of the brightest cluster galaxies

description: We use semi-analytic techniques to study the formation and evolution of brightest cluster galaxies (BCGs). We show the extreme hierarchical nature of these objects and discuss the limits of simple ways to capture their evolution. In a model where cooling flows are suppressed at late times by AGN activity, the stars of BCGs are formed very early (50 per cent at z~5, 80 per cent at z~3) and in many small galaxies. The high star formation rates in these high-z progenitors are fuelled by rapid cooling, not by merger-triggered starbursts. We find that model BCGs assemble surprisingly late: half their final mass is typically locked-up in a single galaxy after z~0.5. Because most of the galaxies accreted onto BCGs have little gas content and red colours, late mergers do not change the apparent age of BCGs. It is this accumulation of a large number of old stellar populations -- driven mainly by the merging history of the dark matter halo itself -- that yields the observed homogeneity of BCG properties. In the second part of the paper, we discuss the evolution of BCGs to high redshifts, from both observational and theoretical viewpoints. We show that our model BCGs are in qualitative agreement with high-z observations. We discuss the hierarchical link between high-z BCGs and their local counter-parts. We show that high-z BCGs belong to the same population as the massive end of local BCG progenitors, although they are not in general the same galaxies. Similarly, high-z BCGs end-up as massive galaxies in the local Universe, although only a fraction of them are actually BCGs of massive clusters.

description: The last decade has seen the government in Aotearoa New Zealand place greater economic focus on exploiting mineral resources. As a result, the matter of Māori rights and interests in relation to these resources is of increased relevance and has become a highly charged national issue. The Waitangi Tribunal (‘Tribunal’) has released a number of reports since 1991 that discuss and make recommendations on Māori rights in relation to various mineral resources including pounamu (greenstone), petroleum and gold. This thesis critically analyses the jurisprudence and associated discourse developed by the Tribunal regarding Māori rights and interests in relation to minerals. The Tribunal’s reports are currently underexplored, yet are vital to understanding the issues, complexities and obstacles associated with claims to mineral rights, not only for Māori but for other Indigenous peoples. This is because the inconsistent approaches and recommendations produced by the Tribunal highlight different ways in which arguments about Māori rights in relation to minerals can be conceived and constructed. The core focus of this thesis is on identifying the legal arguments by which Māori claims to minerals rights in each of the Tribunal reports have been considered, recognised, limited, and/or transformed. This thesis then analyses how the Crown responded to the Tribunal’s reports, and how the Crown and iwi have engaged with each other and the Tribunal over the matter of mineral rights through the Treaty settlement process and the review and subsequent amendment of the primary legislation governing minerals, the Crown Minerals Act 1991 (CMA). In so doing, this thesis provides a picture of Māori rights in relation to minerals, and highlights the unresolved issues between Māori and the Crown through the lens of the Tribunal and its discourse.

description: Background. Although depression is a risk factor for cardiovascular disease (CVD), few clinical trials in people without CVD have examined the effect of depression treatment on CVD-related outcomes. It’s unknown if successful depression treatment improves indicators of CVD risk, such as CVD-relevant health behaviors, traditional CVD risk factors, and CVD events. Methods. We examined data from eIMPACT trial, a phase II randomized controlled trial conducted from 2015-2020. Depressive symptoms, CVD-relevant health behaviors (self-reported CVD prevention medication adherence, sedentary behavior, and sleep quality) and traditional CVD risk factors (blood pressure and lipid fractions) were assessed. Incident CVD events over four years were identified using a statewide health information exchange. Results. The intervention group exhibited greater improvement in depressive symptoms (p < 0.01) and sleep quality (p < 0.01) than the usual care group, but there was no intervention effect on systolic blood pressure (p = 0.36), low-density lipoprotein cholesterol (p = 0.38), high-density lipoprotein cholesterol (p = 0.79), triglycerides (p = 0.76), CVD prevention medication adherence (p = 0.64), or sedentary behavior (p = 0.57). There was an intervention effect on diastolic blood pressure that favored the usual care group (p = 0.02). CVD-relevant health behaviors did not mediate any intervention effects on traditional CVD risk factors. Twenty-two participants (10%) experienced an incident CVD event. The likelihood of an CVD event did not differ between the intervention group (12.1%) and the usual care group (8.3%; HR = 1.45, 95% CI: 0.62-3.40, p = 0.39). Conclusions. Successful depression treatment alone improves self-reported sleep quality but is not sufficient to lower CVD risk of people with depression. Alternative approaches may be needed reduce CVD risk in depression.

description: A simple model for sequential multiphoton ionization by ultra-intense x-rays is presented. The derived scaling of the ion yield with pulse energy quantitatively reproduces the experimental data, which shows that the ion yield increases according to the "power law" behavior typical of multiphoton ionization, followed by saturation at high pulse energies. The calculated average time interval between ionizations for producing ions at a certain charge state is found to be proportional to the pulse duration and independent of all other x-ray pulse parameters. This agrees with previous studies where the kinetic energy of fragment ions with a given charge state produced by intense x-ray ionization of molecules was found to be independent of the pulse energy, but to increase with smaller pulse duration due to the smaller time interval between ionizations.

description: For convex co-compact hyperbolic quotients $X=Γ\backslash\hh^{n+1}$, we analyze the long-time asymptotic of the solution of the wave equation $u(t)$ with smooth compactly supported initial data $f=(f_0,f_1)$. We show that, if the Hausdorff dimension $δ$ of the limit set is less than $n/2$, then $u(t) = C_δ(f) e^{(δ-\ndemi)t} / Γ(δ-n/2+1) + e^{(δ-\ndemi)t} R(t)$ where $C_δ(f)\in C^\infty(X)$ and $||R(t)||=\mc{O}(t^{-\infty})$. We explain, in terms of conformal theory of the conformal infinity of $X$, the special cases $δ\in n/2-\nn$ where the leading asymptotic term vanishes. In a second part, we show for all $\eps>0$ the existence of an infinite number of resonances (and thus zeros of Selberg zeta function) in the strip $\{-nδ-\eps

description: Large higher-order corrections enter the Higgs boson sector of the MSSM via Higgs-boson self-energies. Their effects have to be taken into account for the correct treatment of loop-corrected Higgs-boson mass eigenstates as external (on-shell) or internal particles in Feynman diagrams. We review how the loop corrections, including momentum dependence and imaginary contributions, are correctly taken into account for external (on-shell) Higgs boson and how effective couplings can be derived. The proceedures are implemented in the code FeynHiggs 2.5.

Different possibilities - instrumental biases, very high redshifts, extinction in the host galaxies - are discussed and shown to be important. On the other hand, the dark bursts should not form a new subgroup of long gamma-ray bursts themselves.

From hand to brain and back: Grip forces deliver insight into the functional plasticity of somatosensory processes
Creators: name: Dresp-Langley, Birgitta

Year: 2021
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: The human somatosensory cortex is intimately linked to other central brain functions such as vision, audition, mechanoreception, and motor planning and control. These links are established through brain learning, and display a considerable functional plasticity. This latter fulfills an important adaptive role and ensures, for example, that humans are able to reliably manipulate and control objects in the physical world under constantly changing conditions in their immediate sensory environment. Variations in human grip force are a direct reflection of this specific kind of functional plasticity. Data from preliminary experiments where wearable wireless sensor technology (sensor gloves) was exploited to measure human grip force variations under varying sensory input conditions (eyes open or shut, soft music or hard music during gripping) are discussed here to show the extent to which grip force sensing permits quantifying somatosensory brain interactions and their functional plasticity. Experiments to take this preliminary work further are suggested. Implications for robotics, in particular the development of end-effector robots for upper limb movement planning and control, are brought forward.

description: We numerically study the entanglement dynamics of free fermions on a cubic lattice with potential disorder following a quantum quench. We focus, in particular, on the metal-insulator transition at a critical disorder strength and compare the results to the putative many-body localization (MBL) transition in interacting one-dimensional systems. We find that at the transition point the entanglement entropy grows logarithmically with time $t$ while the number entropy grows $\sim\ln\ln t$. This is exactly the same scaling recently found in the MBL phase of the Heisenberg chain with random magnetic fields suggesting that the MBL phase might be more akin to an extended critical regime with both localized and delocalized states rather than a fully localized phase. We also show that the experimentally easily accessible number entropy can be used to bound the full entanglement entropy of the Anderson model and that the critical properties at the metal-insulator transition obtained from entanglement measures are consistent with those obtained by other probes.

description: The coincidence problem of late cosmic acceleration is a serious riddle in connection with our understanding of the evolution of the Universe. In this paper we show that an interaction between the dark energy component (either phantom or quintessence) and dark matter can alleviate it. In this scenario the baryon component is independently conserved. This generalizes a previous study [S. del Campo, R. Herrera, and D. Pavon, Phys. Rev. D 71, 123529 (2005)] in which neither baryons nor phantom energy were considered.

This places the host at a redshift of z=.923 exceeding the previous record for the highest spectroscopically confirmed short burst redshift of z=.546 held by GRB 051221. This dramatically moves back the time at which we know short bursts were being formed, and suggests that the present evidence for an old progenitor population may be observationally biased.

description: We present a model of a hypersonic, collimated, "single pulse" outflow, produced by an event with an ejection velocity that first grows, reaches a peak, and then decreases again to zero velocity in a finite time (simultaneously, the ejection density can have an arbitrary time-variability). We obtain a flow with a leading "head" and a trailing "tail" that for times greater than the width of the pulse develops a linear, "Hubble law" velocity vs. position. We present an analytic model for a simple pulse with a parabolic ejection velocity vs. time and time-independent mass-loss rate, and compare it to an axisymmetric gasdynamic simulation with parameters appropriate for fast knots in planetary nebulae. This "head/tail plasmon" flow might be applicable to other high-velocity clumps with "Hubble law" tails.

description: Based on kinetic equations for the density matrix, drift-diffusion equations are derived for a two-dimensional electron gas with Rashba spin-orbit coupling. Universal results are obtained for the weak coupling case. Most interesting is the observation that with increasing spin-orbit coupling strengths there is a sharp transition between spin diffusion and ballistic spin transport. For strong spin-orbit coupling, when the elastic scattering time is much larger than the spin relaxation time, undamped spin-coherent waves are identified. The existence of these long-lived spin-coherent states is confirmed by exact analytical results obtained from microscopic kinetic equations valid in the ballistic regime.

description: Agriculture plays a significant role in the global economy, serving as a leading sector in many countries. With a rapidly increasing world population, the demand for food in both quality and quantity has surged. To meet these escalating demands, it becomes imperative to implement transformative changes in agricultural practices. In conventional farming, a substantial workforce is traditionally required for various tasks such as soil nurturing, crop monitoring, pesticide and herbicide application, weed handling, irrigation, and harvesting.

 

Generally, in conventional farming, large number of human labours are required to doing in each and every task like nursing soil, monitoring crop, spraying pesticides, herbicides, weed handling, irrigation, harvesting etc but if we optimized our agriculture resources by Morden Technology, we can do smart and precise farming and bring a new revolution in the agricultural sector. In this study the authors have make efforts to summarised the need, function, purpose, statement, tool representation, advantages of robotics agriculture, use of agricultural robotics in India, automation and robotics changing the face of agriculture (Company), agriculture robots and farm robots, disadvantage of robotic agriculture. It is equally crucial to acknowledge and address the potential disadvantages of incorporating robotics in agriculture. Importantly, governments worldwide are actively endorsing and supporting research in agriculture through the formulation of policies, funding agencies, investment incentives, the provision of rebates and loans.

 

Agricultural robots are specifically designed to aid farmers in various tasks. These robots can be programmed to analyse, automate and perform repetitive and labour-intensive tasks. This capability not only alleviates the burden on farmers but also contributes to an overall increase in production and efficiency.

description: A scalar field having the Coleman-Weinberg type effective potential arises in various contexts of particle physics and serves as a useful framework for discussing cosmic inflation. According to recent studies based on the Markov chain Monte Carlo analysis, the coefficients of such an effective potential are severely constrained by the cosmological data. We investigate the impact of this observation on the physics beyond the Standard Model, focusing on an inflationary model based on the $U(1)_X$-extended Standard Model as a well-motivated example. We examine the parameter region that is not excluded by the Large Hadron Collider (LHC) Run-2 at 139 fb${}^{-1}$ integrated luminosity, and show that the model parameters can be further constrained by the High-Luminosity LHC experiments in the near future. We also comment on the possible reheating mechanism and the dark matter candidates of this scenario.

A Formal Model for Adaptive Free Choice in Complex Systems

Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)

description: In this article, I develop a formal model of free will for complex systems based on emergent properties and adaptive selection. The model is based on a process ontology in which a free choice is a singular process that takes a system from one macrostate to another. I quantify the model by introducing a formal measure of the `freedom' of a singular choice. The `free will' of a system, then, is emergent from the aggregate freedom of the choice processes carried out by the system. The focus in this model is on the actual choices themselves viewed in the context of processes. That is, the nature of the system making the choices is not considered. Nevertheless, my model does not necessarily conflict with models that are based on internal properties of the system. Rather it takes a behavioral approach by focusing on the externalities of the choice process.

Making use of the maximum entropy principle and fluctuation-dissipation theorem, we have shown that the observed fat-tailed distributions of the total number of papers x authored by scientists may result from the density of states function g(x;τ) underlying scientific community. Although different generations of scientists are characterized by different productivity patterns, the function g(x;τ) is inherent to researchers of a given seniority τ, whereas the publish-or-perish phenomenon is caused only by an external field θinfluencing researchers.

description: The use of computed tomography (CT) imaging has become of increasing interest to academic areas outside of the field of medical imaging and industrial inspection, e.g., to biology and cultural heritage research. The pecularities of these fields, however, sometimes require that objects need to be imaged on-site, e.g., in field-work conditions or in museum collections. Under these circumstances, it is often not possible to use a commercial device and a custom solution is the only viable option. In order to achieve high image quality under adverse conditions, reliable calibration and trajectory reproduction are usually key requirements for any custom CT scanning system. Here, we introduce the construction of a low-cost disassemblable CT scanner that allows calibration even when trajectory reproduction is not possible due to the limitations imposed by the project conditions. Using 3D-printed in-image calibration phantoms, we compute a projection matrix directly from each captured X-ray projection. We describe our method in detail and show successful tomographic reconstructions of several specimen as proof of concept.

description: The construction of a resonance theory involving hadrons requires implementing the information from higher scales into the couplings of the effective Lagrangian. We consider the large-Nc chiral resonance theory incorporating scalars and pseudoscalars, and we find that, by imposing LO short-distance constraints on form factors of QCD currents constructed within this theory, the chiral low-energy constants satisfy resonance saturation at NLO in the 1/Nc expansion.

description: We discuss how four-lepton decays of the Z-boson probe currently unconstrained flat directions in the parameter space of the Standard Model Effective Field Theory (SMEFT). We derive the constraints from these decays on four-lepton operators in the SMEFT and show how the LHC data for this process complements probes from neutrino-trident production. Future differential measurements with high-luminosity data can strongly constrain four-lepton operators and remove all flat directions in the four-muon sector of the SMEFT. We comment briefly on the possibility of using rare Z-decays to tau-leptons to probe untested directions in the SMEFT parameter space.

description: Despite several attempts, no efficient cluster algorithm has been constructed for CP(N-1) models in the standard Wilson formulation of lattice field theory. In fact, there is a no-go theorem that prevents the construction of an efficient Wolff-type embedding algorithm. In this paper, we construct an efficient cluster algorithm for ferromagnetic SU(N)-symmetric quantum spin systems. Such systems provide a regularization for CP(N-1) models in the framework of D-theory. We present detailed studies of the autocorrelations and find a dynamical critical exponent that is consistent with z = 0.

description: We compare simulations performed using the Nosé-Hoover and the Langevin thermostats with the Hamiltonian dynamics of a long-range interacting system in contact with a reservoir. We find that while the statistical mechanics equilibrium properties of the system are recovered by all the different methods, the Nosé-Hoover and the Langevin thermostats fail in reproducing the nonequilibrium behavior of such Hamiltonian.

description: A dual-gate InSb nanosheet field-effect device is realized and is used to investigate the physical origin and the controllability of the spin-orbit interaction in a narrow bandgap semiconductor InSb nanosheet. We demonstrate that by applying a voltage over the dual gate, efficiently tuning of the spin-orbit interaction in the InSb nanosheet can be achieved. We also find the presence of an intrinsic spin-orbit interaction in the InSb nanosheet at zero dual-gate voltage and identify its physical origin as a build-in asymmetry in the device layer structure. Having a strong and controllable spin-orbit interaction in an InSb nanosheet could simplify the design and realization of spintronic deceives, spin-based quantum devices and topological quantum devices.

description: We first review the description of flag manifolds in terms of Pluecker coordinates and coherent states. Using this description, we construct fuzzy versions of the algebra of functions on these spaces in both operatorial and star product language. Our main focus is here on flag manifolds appearing in the double fibration underlying the most common twistor correspondences. After extending the Pluecker description to certain supersymmetric cases, we also obtain the appropriate deformed algebra of functions on a number of fuzzy flag supermanifolds. In particular, fuzzy versions of Calabi-Yau supermanifolds are found.

The Self-Employed Women’s Association: ideology in action
Creators: name: Appell, Virginia
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation presents an anthropological examination of the efforts of the Self- Employed Women's Association (SEWA) in Ahmedabad, Gujarat, India, to effect social change. The study is based on fieldwork carried out in 1993 and 1994. SEWA attempts to improve the situation of economically marginal women in urban and rural Gujarat, by altering the conditions in which they labour. SEWA works from a reformist position, which allows it to (i) criticise existing development practices, (ii) influence government policies concerning the very poor and (iii) assist in the implementation of those government programmes intended to benefit the very poor. I put forth the argument that SEWA's most useful contribution to social change may lie in its efforts to reconceptualise existing relations between labour, gender and poverty. SEWA has attempted to create different, and more "positive", perceptions of the economicallymarginal women, and to bring the issues which concern them to wider public awareness. The dissertation describes SEWA's ideological and practical struggles to effect these changes. The bases of the ideology are the organisation's efforts to define its members and its purpose in the terms it finds appropriate and its insistence that development which is to benefit women must be focussed exclusively on them. The organisation's strategies include the establishment of a powerful organisation which is now linked with national and international agencies committed to improving the economic conditions of the poor. Other strategies include mounting legal challenges to unfair practices, creating employment, regularising relations between employers and employees and working to establish bonds between women of different conimunities and sub-castes, through its efforts to alter women's perceptions of themselves. A number of internal struggles between highly educated middle class activists with global worldviews and the women SEWA designates as self-employed are examined. Two of the organisation's efforts to put ideology into action, and the social factors which impeded those efforts, are described. Some of those impediments are internal to the organisation, such as conflicts between members and organisers about the purpose of the organisation, and their different roles in it. Others are external, and are situated in the domestic domains of the members' lives and in the social and economic context of the city of Ahmedabad. The fact that only women can belong to SEWA is a crucial element in the organisation's construction of a development alternative, but that fact has the paradoxical effect of isolating women conceptually from the social and familial networks in which they live and work. In the future, SEWA may have to decide whether to retain its alternative, women-focussed approach or to integrate its development activities into the wider context of economically marginal women and men.
Boundary Layer Circumplanetary Accretion: How Fast Could an Unmagnetized Planet Spin Up Through Its Disk?

description: Gas giant planets are expected to accrete most of their mass via a circumplanetary disk. If the planet is unmagnetized and initially slowly rotating, it will accrete gas via a radially narrow boundary layer and rapidly spin up. Radial broadening of the boundary layer as the planet spins up reduces the specific angular momentum of accreted gas, allowing the planet to find a terminal rotation rate short of the breakup rate. Here, we use axisymmetric viscous hydrodynamic simulations to quantify the terminal rotation rate of planets accreting from their circumplanetary disks. For an isothermal planet-disk system with a disk scale height $h/r =0.1$ near the planetary surface, spin up switches to spin down at between 70\% and 80\% of the planet's breakup angular velocity. In a qualitative difference from vertically-averaged models -- where spin down can co-exist with mass accretion -- we observe \emph{decretion} accompanying solutions where angular momentum is being lost. The critical spin rate depends upon the disk thickness near the planet. For an isothermal system with a disk scale height of $h/r = 0.15$ near the planet, the critical spin rate drops to between 60\% and 70\% of the planet's breakup angular velocity. In the disk outside the boundary layer, we identify meridional circulation flows, which are unsteady and instantaneously asymmetric across the mid-plane. The simulated flows are strong enough to vertically redistribute solid material in early-stage satellite formation. We discuss how extrasolar planetary rotation measurements, when combined with spectroscopic and variability studies of protoplanets with circumplanetary disks, could determine the role of magnetic and non-magnetic processes in setting giant planet spins.

description: Accounting for important interaction effects can improve prediction of many statistical learning models. Identification of relevant interactions, however, is a challenging issue owing to their ultrahigh-dimensional nature. Interaction screening strategies can alleviate such issues. However, due to heavier tail distribution and complex dependence structure of interaction effects, innovative robust and/or model-free methods for screening interactions are required to better scale analysis of complex and high-throughput data. In this work, we develop a new model-free interaction screening method, termed Kendall Interaction Filter (KIF), for the classification in high-dimensional settings. The KIF method suggests a weighted-sum measure, which compares the overall to the within-cluster Kendall's $τ$ of pairs of predictors, to select interactive couples of features. The proposed KIF measure captures relevant interactions for the clusters response-variable, handles continuous, categorical or a mixture of continuous-categorical features, and is invariant under monotonic transformations. We show that the KIF measure enjoys the sure screening property in the high-dimensional setting under mild conditions, without imposing sub-exponential moment assumptions on the features' distributions. We illustrate the favorable behavior of the proposed methodology compared to the methods in the same category using simulation studies, and we conduct real data analyses to demonstrate its utility.
