The density gradient expansion of correlation functions
Creators: name: van Leeuwen, Robert
Publisher: name: arXiv
Year: 2013
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We present a general scheme based on nonlinear response theory to calculate the expansion of correlation functions such as the pair-correlation function or the exchange-correlation hole of an inhomogeneous many-particle system in terms of density derivatives of arbitrary order. We further derive a consistency condition that is necessary for the existence of the gradient expansion. This condition is used to carry out an infinite summation of terms involving response functions up to infinite order from which it follows that the coefficient functions of the gradient expansion can be expressed in terms the local density profile rather than the background density around which the expansion is carried out. We apply the method to the calculation of the gradient expansion of the one-particle density matrix to second order in the density gradients and recover in an alternative manner the result of Gross and Dreizler (Z. Phys. A 302, 103 (1981)) which was derived using the Kirzhnits method. The nonlinear response method is more general and avoids the turning point problem of the Kirzhnits expansion. We further give a description of the exchange hole in momentum space and confirm the wave vector analysis of Langreth and Perdew (Phys. Rev. B21, 5469 (1980)) for this case. This is used to derive that the second order gradient expansion of the system averaged exchange hole satisfies the hole sum rule and to calculate the gradient coefficient of the exchange energy without the need to regularize divergent integrals.

description: A novel, one-pot, multicomponent synthesis of triazolothiadiazine derivatives have been achieved starting from 4-amino-4H-1,2,4-triazole-3,5-dithiol and variously substituted phenacyl bromides. The synthesis involves the simultaneous formation of two C–S and one C = N bond. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR, and mass spectral data. The advantages of this method are good yields, high purity, shorter reaction times and simple purification technique. The synthesized target compounds were screened for their in vitro anticancer activity at concentration 10−5 M against 60 cancer cell lines. Among all the compounds, 1-(4-Fluorophenyl)-2-((6-(4-fluorophenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-3-yl) thio)ethanone (4d), 1-(4-Bromophenyl)-2-((6-(4-bromophenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-3-yl)thio) ethanone (4f), and 2-((6-(4-Chlorophenyl)-7H-[1,2,4] triazolo[3,4-b][1,3,4]thiadiazin-3-yl)thio)-1-(4-fluorophenyl)ethanone (4l) exhibited significant activity in terms of growth percent against renal cancer OU-31 cell line with 47.42%, 46.76%, 48.14%. The compound 2-((6-(4-Chlorophenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-3-yl)thio)-1-(4-fluorophenyl) ethanone (4l) also exhibited significant activity on leukemia MOLT-4 cell line with 49.82%.

description: Two previously unknown variable stars in the crowded central region of the globular cluster NGC 6981 are presented. The observations were made using the Electron Multiplying CCD (EMCCD) camera at the Danish 1.54m Telescope at La Silla, Chile.The two variables were not previously detected by conventional CCD imaging because of their proximity to a bright star. This discovery demonstrates that EMCCDs are a powerful tool for performing high-precision time-series photometry in crowded fields and near bright stars, especially when combined with difference image analysis (DIA).

description: We point out that perturbation theory in conjunction with the renormalization group (RG) puts a severe constraint on the structure of the large-N non-perturbative glueball propagators in SU(N) pure YM, in QCD and in n=1 SUSY QCD with massless quarks, or in any confining asymptotically-free gauge theory massless in perturbation theory. For the scalar and pseudoscalar glueball propagators in pure YM and QCD with massless quarks we check in detail the RG-improved estimate to the order of the leading and next-to-leading logarithms by means of a remarkable three-loop computation by Chetyrkin et al. We investigate as to whether the aforementioned constraint is satisfied by any of the scalar or pseudoscalar glueball propagators computed in the framework of the AdS String/ large-N Gauge Theory correspondence and of a recent proposal based on a Topological Field Theory underlying the large-N limit of YM. We find that none of the proposals for the scalar or the pseudoscalar glueball propagators based on the AdS String/ large-N Gauge Theory correspondence satisfies the constraint, actually as expected, since the gravity side of the correspondence is in fact strongly coupled in the ultraviolet. On the contrary, the Topological Field Theory satisfies the constraint that follows by the asymptotic freedom.

description: Статья посвящена изучению места мифа при построении территориальной идентичности. Обоснована значимость мифологического контента для позиционирования бренда территории. В данном случае имеется ввиду миф традиционный, архаичный — разнообразные формы местного фольклора, предания, легенды, сказки имеют жизнеутверждающий характер, отражают нравственные устои, мировоззрение, ценности жителей данной территории. Но наличие мифологических мотивов может положительно сказаться на развитии экономики и туристской индустрии территории только при условии, если они будут правильно «упакованы» и преподнесены, будут активироваться не стихийно, а целенаправленно, систематично как готовый имиджевый продукт. Автор статьи выделяет оптимальные способы использования мифологических ресурсов в российском территориальном брендинге: инвестиционный проект создания туристско-рекреационного кластера «Великий Устюг — родина Деда Мороза», туристский бренд «Кострома и Берендеево царство — родина Снегурочки», Шадринский гусь как символ города, сиреневая роща в Диканьке, посаженная Н.В.Гоголем, Дом Грушеньки в Старой Руссе рядом с домом Ф.М.Достоевского, всероссийский культурно-просветительский проект журналиста Алексея Козловского «Сказочная карта России» и т.д. На примере Великого Новгорода автор показывает пути активации мифа при выстраивании позитивного имиджа города: организация театрализованных экскурсий и туров, проведение фольклорных праздников, создание в СМИ просветительских проектов, посвященных новгородским былинам и преданиям.

description: Рассматривается архетипическая мифология, идеологические и геополитические контексты фильма «Солнцестояние» как типичного голливудского кинопроизведения в жанре «фолк-хоррор». Мифосимволический анализ характерных для картины сценариев визуализации практики культурной апроприации недвусмысленно свидетельствует о наличии у молодых представителей североамериканской культуры бессознательного колониального комплекса в отношении представителей иных культурных традиций. Идеологическая доминанта фильма опирается на пропаганду цивилизационного превосходства вестернизированной и христианизированной культуры. Молодое поколение североамериканских потребителей получает символическое воздаяние от коренного населения, выступающего репрезентантом «ужасной» языческой символики и примитивной общинной обрядности. Опираясь на общекультурные символы, «Солнцестояние» фактически обличает действующую модель межкультурной коммуникации посредством демонстрации смысловой мощи традиционной культуры.
Potts Models with (17) Invisible States on Thin Graphs

description: The order of a phase transition is usually determined by the nature of the symmetry breaking at the phase transition point and the dimension of the model under consideration. For instance, q-state Potts models in two dimensions display a second order, continuous transition for q = 2,3,4 and first order for higher q. Tamura et al recently introduced Potts models with "invisible" states which contribute to the entropy but not the internal energy and noted that adding such invisible states could transmute continuous transitions into first order transitions. This was observed both in a Bragg-Williams type mean-field calculation and 2D Monte-Carlo simulations. It was suggested that the invisible state mechanism for transmuting the order of a transition might play a role where transition orders inconsistent with the usual scheme had been observed. In this paper we note that an alternative mean-field approach employing 3-regular random ("thin") graphs also displays this change in the order of the transition as the number of invisible states is varied, although the number of states required to effect the transmutation, 17 invisible states when there are 2 visible states, is much higher than in the Bragg-Williams case. The calculation proceeds by using the equivalence of the Potts model with 2 visible and r invisible states to the Blume-Emery-Griffiths (BEG) model, so a by-product is the solution of the BEG model on thin random graphs.

description: We construct the first explicit example of a simplicial 3-ball B_{15,66} that is not collapsible. It has only 15 vertices. We exhibit a second 3-ball B_{12,38} with 12 vertices that is collapsible and evasive, but not shellable. Finally, we present the first explicit triangulation of a 3-sphere S_{18, 125} (with only 18 vertices) that is not locally constructible. All these examples are based on knotted subcomplexes with only three edges; the knots are the trefoil, the double trefoil, and the triple trefoil, respectively. The more complicated the knot is, the more distant the triangulation is from being polytopal, collapsible, etc. Further consequences of our work are: (1) Unshellable 3-spheres may have vertex-decomposable barycentric subdivisions. (This shows the strictness of an implication proven by Billera and Provan.) (2) For d-balls, vertex-decomposable implies non-evasive implies collapsible, and for d=3 all implications are strict. (This answers a question by Barmak.) (3) Locally constructible 3-balls may contain a double trefoil knot as a 3-edge subcomplex. (This improves a result of Benedetti and Ziegler.) (4) Rudin's ball is non-evasive.

description: We study the Renyi mutual information of classical systems characterized by a transfer matrix. We first establish a general relationship between the Renyi mutual information of such classical mixtures of configuration states, and the Renyi entropy of a corresponding Rokhsar-Kivelson--type quantum superposition. We then focus on chiral and nonchiral kagome-ice systems, classical spin liquids on the kagome lattice, which respectively have critical and short-range correlations. Through a mapping of the chiral kagome ice to the quantum Liftshitz critical field theory, we predict a universal subleading term in the Renyi mutual information of this classical spin liquid, which can be realized in the pyrochlore spin ice in a magnetic field. We verify our prediction with direct numerical transfer-matrix computations, and further demonstrate that the nonchiral kagome ice (and the corresponding quantum Rokhsar-Kivelson superposition) is a topologically trivial phase. Finally, we argue that the universal term in the mutual information of the chiral kagome ice is fragile against the presence of defects.

description: We present a new library of high-resolution synthetic spectra based on the stellar atmosphere code PHOENIX that can be used for a wide range of applications of spectral analysis and stellar parameter synthesis. The spherical mode of PHOENIX was used to create model atmospheres and to derive detailed synthetic stellar spectra from them. We present a new self-consistent way of describing micro-turbulence for our model atmospheres. The synthetic spectra cover the wavelength range from 500AA to 50.000AA with resolutions of R=500.000 in the optical and near IR, R=100.000 in the IR and a step size of 0.1AA in the UV. The parameter space covers 2.300K<=Teff<=12.000K, 0.0<=log(g)<=+6.0, -4.0<=[Fe/H]<=+1.0, and -0.2<=[alpha/Fe]<=+1.2. The library is a work in progress and we expect to extend it up to Teff=25.000 K.

description: In this paper, we introduce a three-point analogue of Ćirić-Reich-Rus type mappings, termed as generalized Ćirić-Reich-Rus type mappings. We demonstrate that these mappings generally exhibit discontinuity within their domain of definition but necessitate continuity at their fixed points. We showcase the existence and non-uniqueness of fixed points for these generalized Ćirić-Reich-Rus type mappings. By imposing additional conditions, specifically asymptotic regularity and continuity, we extend the applicability of fixed-point theorems to a broader class of mappings. Finally, we obtain two fixed point theorems for generalized Ćirić-Reich-Rus type mappings in metric spaces that are not necessarily complete.

description: The dynamics of the Brans-Dicke theory with a scalar field potential function is investigated. We show that the system with a barotropic matter content can be reduced to an autonomous three-dimensional dynamical system. For an arbitrary potential function we found the values of the Brans-Dicke parameter for which a global attractor in the phase space representing de Sitter state exists. Using linearized solutions in the vicinity of this critical point we show that the evolution of the Universe mimics the $Λ$CDM model. From the recent Planck satellite data, we obtain constraints on the variability of the effective gravitational coupling constant as well as the lower limit of the mass of the Brans-Dicke scalar field at the de Sitter state.

A Slow Ride into the Past: The Chinese Trishaw Industry in Singapore, 1942-1983
Creators: name: Lim, Jason
Publisher: name: Monash University
Year: 2023
Subjects: Asian history

description: The trishaw was introduced to Singapore after the surrender of the British in 1942. After the end of the war, the trishaw continued to be a popular mode of transport as it was cheap and the service was seen to be personalised. The trishaw industry was dominated by two Chinese minority dialect groups and their ubiquitous presence could be a threat to local government in the 1940s and 1950s. By the time Singapore achieved independence in 1965, however, the trishaw was regarded as backward and public perception of the trishaw riders also changed. As the island nation embarked on a programme of economic modernisation, the trishaws were increasingly squeezed out. Through the use of travelogues, government records, trishaw associations’ records and oral history interviews, this book studies the personal experiences of those involved in the industry and the role local and national governments play in its rise and decline.

description: Duality relations between continuous-state and discrete-state stochastic processes with continuous-time have already been studied and used in various research fields. We propose extended duality relations, which enable us to derive discrete-state stochastic processes from arbitrary diffusion-type partial differential equations. The derivation is based on the Doi-Peliti formalism and the algebraic probability theory, and it will be clarified that additional states for the discrete-state stochastic processes must be considered in some cases.

Relaxation in N-body simulations of disk galaxies

description: I use N-body simulations with two mass species of particles to demonstrate that disk galaxy simulations are subject to collisional relaxation at a higher rate than is widely assumed. Relaxation affects the vertical thickness of the disk most strongly, and drives the velocity ellipsoid to a moderately flattened shape similar to that observed for disk stars in the solar neighborhood. The velocity ellipsoid in simulations with small numbers of particles quickly approaches this shape, but shot noise also dominates the in-plane behavior. Simulations with higher, but reachable, numbers of particles relax slowly enough to be considered collisionless, allowing the in-plane dispersions to rise due to spiral activity without heating the vertical motions. Relaxation may have affected many previously published simulations of the formation and evolution of galaxy disks.

Isospin violating dark matter being asymmetric

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The isospin violating dark matter (IVDM) scenario offers an interesting possibility to reconcile conflicting results among direct dark matter search experiments for a mass range around 10 GeV. We consider two simple renormalizable IVDM models with a complex scalar dark matter and a Dirac fermion dark matter, respectively, whose stability is ensured by the conservation of "dark matter number". Although both models successfully work as the IVDM scenario with destructive interference between effective couplings to proton and neutron, the dark matter annihilation cross section is found to exceed the cosmological/astrophysical upper bounds. Then, we propose a simple scenario to reconcile the IVDM scenario with the cosmological/astrophysical bounds, namely, the IVDM being asymmetric. Assuming a suitable amount of dark matter asymmetry has been generated in the early Universe, the annihilation cross section beyond the cosmological/astrophysical upper bound nicely works to dramatically reduce the anti-dark matter relic density and as a result, the constraints from dark matter indirect searches are avoided. We also discuss collider experimental constraints on the models and an implication to Higgs boson physics.

description: This paper completes the study of the next-to-leading order (NLO) QCD corrections to massive color-octet vector boson production at the LHC and Tevatron. The massive color-octet vector bosons are generically referred to as colorons. Building on our previous calculation of quark-initiated coloron production at NLO, we use the pinch technique to investigate coloron production via gluon fusion. We demonstrate that this one-loop production amplitude is finite, and find that its numerical contribution to coloron production is typically four orders of magnitude smaller than the contribution from quark annihilation. Coloron production via gluon fusion is therefore only relevant if the colorons are (nearly) fermiophobic. We then present extensive plots and tables of our full results for NLO coloron production at the Tevatron and the LHC.

description: Multipartite entanglement of large numbers of physically distinct linear resonators is of both fundamental and applied interest, but there have been no feasible proposals to date for achieving it. At the same time, the Bose-Hubbard model with attractive interactions (ABH) is theoretically known to have a phase transition from the superfluid phase to a highly entangled nonlocal superposition, but observation of this phase transition has remained out of experimental reach. In this theoretical work, we jointly address these two problems by (1) proposing an experimentally accessible quantum simulation of the ABH phase transition in an array of tunably coupled superconducting circuit microwave resonators and (2) incorporating the simulation into a highly scalable protocol that takes as input any microwave resonator state with negligible occupation of number states |0> and |1> and nonlocally superposes it across the whole array of resonators. The large-scale multipartite entanglement produced by the protocol is of the W-type, which is well-known for its robustness. The protocol utilizes the ABH phase transition to generate the multipartite entanglement of all of the resonators in parallel, and is therefore deterministic and permits an increase in resonator number without increase in protocol complexity; the number of resonators is limited instead by system characteristics such as resonator frequency disorder and inter-resonator coupling strength. Only one local and two global controls are required for the protocol. We numerically demonstrate the protocol with realistic system parameters, and estimate that current experimental capabilities can realize the protocol with high fidelity for greater than 40 resonators.

 Hypoaspis pentodoni Costa, 1971: 71.
 Specimens examined. Two females, Karaj, Nazarabad, 35°54' N, 50°38' E, alt 1230 m, 12 July 2009, O. Joharchi coll., on adult Polyphylla olivieri.
 Notes. This species was described from Israel, on the beetle Pentodon bispinosus. It is now recorded from Iran on a different species of host. Costa (1971) reported a macroseta on genu IV in this species, but his illustration and the type specimens show only setae of normal length (A.S. Baker, pers. comm.), and that is consistent with our specimens. This species may be recognised by the short setae in the central area of the dorsal shield and its relatively small sternal shield, which is wider than long.

The development of a conceptual framework for sport coaching

description: This synopsis of existing published work provides a rationale for, and describes the development of, a conceptual framework for the study of sport coaching. The framework comprises an extensive and comprehensive set of constructs and relationships that form a basis for discourse and the conduct of research, education and development. The origins of the framework are identified, within an academic field of study that was under-theorised, under-resourced and displayed ill-defined concepts. Each of the submitted works is then described and its contribution to a coherent thread of conceptual development illustrated. There is an attempt to situate the incremental development of the framework within the understanding of coaching concepts at that time. Key features of this conceptual framework are described in detail and their insinuation into the literature illustrated: coaching as process, definitions of coaching, roles and boundaries, coaching domains, models of coaching and a coordination function. An analysis of later publications demonstrates how these concepts have been further elaborated over an extended period of time in response to a maturing field of study. Although judged to have impacted successfully, particularly the notion of coaching domains, the synopsis recommends that more needs to be done to emphasise the importance of conceptual clarity, especially in research design and dissemination. Attention is drawn to the sport coaching construct as a family of roles, identification of core functions, the contextual particularity of coaching practice and expertise, and the conceptual precursors of coaches’ decision making. An evaluative summary concludes that key concepts have impacted policy documentation and the academic debate. The conceptual framework, as identified in these works, has acted as a reference point for academic writing and research, and has made a coherent, original and substantial contribution to the academic study of sport coaching.

description: Estimation of a function, or its derivatives via nonparametric regression requires selection of one or more tuning parameters. In the present work, we propose a tuning parameter selection criterion called DCp for nonparametric derivative estimation in random design. Our criterion is general in that it can be applied with any nonparametric estimation method which is linear in the observed outcomes. Charnigo et al. [A generalized Cp criterion for derivative estimation. Technometrics. 2011;53(3):238–253] had proposed a GCp criterion for a similar purpose, assuming values of the covariate to be fixed and constant error variance. Here we consider the setting with random design and non-constant error variance since the covariate values will not generally be fixed and equally spaced in real data applications. We justify DCp in this setting both theoretically and by simulation. We also illustrate use of DCp with two economics data sets.

description: The Simple Image Presentation Interface (SIPI) is a multithreaded, high-performance, IIIF compatible media server developed by the Data and Service Center for the Humanities (DaSCH) at the University of Basel. It is designed to be used by archives, libraries, and other institutions that need to preserve high-quality images while making them available online. SIPI has implemented the IIIF Image API 3.0, and efficiently converts between image formats, preserving metadata contained in image files. In particular, if images are stored in JPEG 2000 format, SIPI can convert them on the fly to formats that are commonly used on the Internet. It offers a flexible framework for specifying authentication and authorisation logic in Lua scripts. In addition SIPI preserves most of the EXIF, IPTC and XMP metadata and can preserve or transform ICC colour profiles. SIPI is free software, released under the GNU Affero General Public License. It is written in C++ and runs on Linux and Mac OS. For the time being, the user has to provide a licensed source of the kakadu software to compile SIPI. This lightning talk given at the 2021 IIIF Annual Conference was an opportunity to present the main functionalities of SIPI and to give hints on future developments.

description: We consider a simple extension of the Standard Model (SM) that incorporates a Majorana fermion dark matter and a charged scalar particle with a coupling to the SM leptons through renormalizable terms. Another renormalizable term involving the charged scalar and the Higgs boson gives rise to interactions between the dark matter and SM quarks at the one-loop level, which induce the elastic scatterings between dark matter and nucleus. The same term also affects the effective coupling of the Higgs boson to diphoton through a one-loop diagram with the charged scalar. Therefore, our model predicts a correlation between the spin-independent cross section for dark matter-nucleus elastic scatterings and a new contribution to the effective Higgs boson coupling to diphoton. When the spin-dependent cross section is large enough to be tested in future direct dark matter detection experiments, the Higgs-diphoton decay rate shows a sizable deviation from the SM prediction. We also consider the case where the fermion dark matter is a Dirac particle. Most of discussions is similar to the Majorana case, but we find that the magnetic dipole moment of the Dirac fermion dark matter is loop-induced and this interaction dominates the spin-independent cross section for dark matter-nucleus elastic scatterings. We find that the resultant cross section is about an order of magnitude below the current experimental bound and hence can be tested in the near future.

description: This paper considers the pretest and shrinkage estimation methods for estimating regression parameters of the generalized log-logistic proportional hazard (PH) model. This model is a simple extension of the log-logistic model, which is closed under the PH relationship. The generalized log-logistic PH model also has attributes similar to those of the Weibull model. We consider this model for right-censored data when some parameters shrink to a restricted subspace. This subspace information on the parameters is used to shrink the unrestricted model estimates toward the restricted model estimates. We then optimally combine the unrestricted and restricted estimates in order to define pretest and shrinkage estimators. Although this estimation procedure may increase bias, it also reduces the overall mean squared error. The efficacy of the proposed model and estimation techniques are shown using a simulation study as well as an application to real data. We also compare the performance of generalized log-logistic, Weibull, and Cox PH models for unimodal and increasing hazards. The shrinkage estimator poses less risk than the maximum likelihood estimator when the shrinkage dimension exceeds two; this is shown through simulation and real data applications.

description: The recent analysis of the Planck results reveals a tension between the best fits for (Ωm0, H0) derived from the cosmic microwave background or baryonic acoustic oscillations on the one hand, and the Hubble diagram on the other hand. These observations probe the universe on very different scales since they involve light beams of very different angular sizes; hence the tension between them may indicate that they should not be interpreted the same way. More precisely, this Letter questions the accuracy of using only the (perturbed) Friedmann-Lemaître geometry to interpret all the cosmological observations, regardless of their angular or spatial resolution. We show that using an inhomogeneous "Swiss-cheese" model to interpret the Hubble diagram allows to reconcile it with the Planck results. Such an approach does not require us to invoke new physics nor to violate the Copernican principle.
