description: Using the density matrix renormalization group, we calculate the energy of a domain wall in the 2D t-J model as a function of the linear hole density ρ_\ell, as well as the interaction energy between walls, for J/t=0.35. Based on these results, we conclude that the ground state always has domain walls for dopings 0 < x < 0.3. For x < 0.125, the system has (1,0) domain walls with ρ_\ell ~ 0.5, while for 0.125 < x < 0.17, the system has a possibly phase-separated mixture of walls with ρ_\ell ~ 0.5 and ρ_\ell =1. For x > 0.17, there are only walls with ρ_\ell =1. For ρ_\ell = 1, diagonal (1,1) domain walls have very nearly the same energy as (1,0) domain walls.

description: Sparse model selection is ubiquitous from linear regression to graphical models where regularization paths, as a family of estimators upon the regularization parameter varying, are computed when the regularization parameter is unknown or decided data-adaptively. Traditional computational methods rely on solving a set of optimization problems where the regularization parameters are fixed on a grid that might be inefficient. In this paper, we introduce a simple iterative regularization path, which follows the dynamics of a sparse Mirror Descent algorithm or a generalization of Linearized Bregman Iterations with nonlinear loss. Its performance is competitive to \texttt{glmnet} with a further bias reduction. A path consistency theory is presented that under the Restricted Strong Convexity (RSC) and the Irrepresentable Condition (IRR), the path will first evolve in a subspace with no false positives and reach an estimator that is sign-consistent or of minimax optimal $\ell_2$ error rate. Early stopping regularization is required to prevent overfitting. Application examples are given in sparse logistic regression and Ising models for NIPS coauthorship.

description: We discuss two nonlocal models of electrodynamics in which the nonlocality is induced by the acceleration of the observer. Such an observer actually measures an electromagnetic field that exhibits persistent memory effects. We compare Mashhoon's model with a new ansatz developed here in the framework of charge & flux electrodynamics with a constitutive law involving the Levi-Civita connection as seen from the observer's local frame and conclude that they are in partial agreement only for the case of constant acceleration.

description: The capacity of popular classical interatomic potentials to describe elastic properties of graphene is tested. The Tersoff potential, Brenner reactive bond-order potentials REBO-1990, REBO-2000, REBO-2002 and AIREBO as well as LCBOP, PPBE-G, ReaxFF-CHO and ReaxFF-C2013 are considered. Linear and non-linear elastic response of graphene under uniaxial stretching is investigated by static energy calculations. The Young's modulus, Poisson's ratio and high-order elastic moduli are verified against the reference data available from experimental measurements and ab initio studies. The density functional theory calculations are performed to complement the reference data on the effective Young's modulus and Poisson's ratio at small but finite elongations. It is observed that for all the potentials considered, the elastic energy deviates remarkably from the simple quadratic dependence already at elongations of several percent. Nevertheless, LCBOP provides the results consistent with the reference data and thus realistically describes in-plane deformations of graphene. Reasonable agreement is also observed for the computationally cheap PPBE-G potential. REBO-2000, AIREBO and REBO-2002 give a strongly non-linear elastic response with a wrong sign of the third-order elastic modulus and the corresponding results are very far from the reference data. The ReaxFF potentials drastically overestimate the Poisson's ratio. Furthermore, ReaxFF-C2013 shows a number of numerical artefacts at finite elongations. The bending rigidity of graphene is also obtained by static energy calculations for large-diameter carbon nanotubes. The best agreement with the experimental and ab initio data in this case is achieved using the REBO-2000, REBO-2002 and ReaxFF potentials. Therefore, none of the considered potentials adequately describes both in-plane and out-of-plane deformations of graphene.

description: We present a stochastic analysis of a data set consisiting of 10^6 quotes of the US Doller - German Mark exchange rate. Evidence is given that the price changes x(tau) upon different delay times tau can be described as a Markov process evolving in tau. Thus, the tau-dependence of the probability density function (pdf) p(x) on the delay time tau can be described by a Fokker-Planck equation, a gerneralized diffusion equation for p(x,tau). This equation is completely determined by two coefficients D_{1}(x,tau) and D_{2}(x,tau) (drift- and diffusion coefficient, respectively). We demonstrate how these coefficients can be estimated directly from the data without using any assumptions or models for the underlying stochastic process. Furthermore, it is shown that the solutions of the resulting Fokker-Planck equation describe the empirical pdfs correctly, including the pronounced tails.

Momentum in the dynamics of variable-mass systems: classical and relativistic case

Year: 2018
Subjects: subject: Classical Physics (physics.class-ph)

description: We discuss a role of a momentum vector in the description of dynamics of systems with variable mass, and show some ambiguity in expressing the 2nd Newtonian law of dynamics in terms of momentum change in time for variable-mass systems. A simple expression that the time-derivative of the momentum of the body with variable mass is equal to the net external force is not always true (only if a special frame of reference is assumed). In basic textbooks and multiple lecture notes the correct equation of motion for a variable-mass system (including relative velocities of the masses entering or leaving the body) is not sufficiently well discussed, leading to some problems with understanding the dynamics of these systems among students. We also show how the equation of motion in classical case (in translational motion) can be easily expanded to the relativistic case and discuss a motion of a relativistic rocket. For the non-relativistic case also a rotational motion is discussed. It is of course true, that most of the good literature treats the problem accurately, but some of the commonly used textbooks do not. The purpose of our letter is to pay attention to the problem of dynamics of variable-mass systems and show yet another perspective of the subject.

description: The DC-response, namely the $I$-$V$ and $G$-$V$ charateristics, of a variety of composite materials are in general found to be nonlinear. We attempt to understand the generic nature of the response charactersistics and study the peculiarities associated with them. Our approach is based on a simple and minimal model bond percolative network. We do simulate the resistor network with appropritate linear and nonlinear bonds and obtain macroscopic nonlinear response characteristics. We discuss the associated physics. An effective medium approximation (EMA) of the corresponding resistor network is also given.

Multi-analytical approaches for the identification of microplastics in various environmental matrices
Creators: name: Sipps, Karli
Publisher: name: No Publisher Supplied
Year: 2021

description: Microplastics (MP), synthetic plastic particles less than 5 mm in size, are a growing concern due to the potential negative impact they may have on the environment. Chemical characterization of MP is important for potential source tracking as well as understanding fate and transport. Spectroscopic techniques, such as Fourier-transform infrared (FTIR) and Raman spectroscopy, have been widely used for this purpose. However, the presence of additives or pigments, as well as oxidation or degradation that occurs either through natural weathering processes or as a result of sample preparation methods used to extract MP from environmental matrices, can hinder straightforward identification of MP when matching the sample spectrum to a reference database. The purpose of this work was to combine multiple analytical techniques for the characterization of MP in various environmental samples. Surface water and zooplankton samples collected at various sites in the Hudson-Raritan Estuary were analyzed using both FTIR and Raman microscopy. Use of these complementary techniques allowed for more comprehensive identification of complex MP and the analysis of particles with a wide range of morphologies and physical properties that may be limited by the use of a single technique. MP were found in surface water samples from each site and primarily were polyethylene and polypropylene, many of which exhibited surface oxidation or the presence of pigments/dyes that complicated spectral analysis. MP were also detected in all zooplankton samples, including three different species, through the combined use of Raman microscopy and FTIR imaging that allowed for sample analysis without introduction of visual bias. FTIR and Raman were also combined with thermoanalytical techniques, differential scanning calorimetry (DSC) and thermogravimetric analysis coupled with IR spectroscopy for evolved gas analysis (TGA-IR) in order to identify mixtures of known MP, rubbers and MP in river bed sediment samples. In order to aid data analysis, 40 plastic samples, consisting of 23 different polymer types, were oxidized via an established nitric acid digestion protocol and analyzed to investigate resulting changes to MP spectra and thermal properties. All spectral and thermal property changes were documented and spectra were compiled as a reference library for the benefit of future analyses.

description: Physical habitat models represent a widely used tool in river management, yet, there is a growing consensus—particularly for large rivers—that fundamental principles have limits, and it is evident that improved methodologies for assessment and design are needed. Here, we suggest a framework that takes steps towards resolving some of these issues, using changes of fish habitat in a large, regulated river as a case study. First, we propose using hydrodynamic modelling in combination with a fuzzy rule-based classification as a tool to delineate and quantify meso-scale fish habitat. Variability in spatial and temporal extent of mesohabitats can be modelled across a range of flows and under non-wadable conditions when standard mesohabitat surveys become largely unfeasible. Second, research effort and empirical data on habitat use and preference of fishes is typically focused on a small group of species and limited for many imperilled or elusive taxa; we suggest using expert knowledge to expand beyond one or a few species to build the biological models for a community-level assessment until empirical data becomes available. Third, sources of uncertainty that are linked to both fundamental elements of habitat models, namely the biological and hydrodynamic components, need to be quantified and reported in modelling outcomes. The steps described in our modelling framework represent key tools for river managers charged with developing environmental flows guidelines in large, regulated rivers.
Chinese Language Learning in Higher Education in Pakistan
Creators: name: Ahmad, Adeeba
Publisher: name: Zenodo
Year: 2021

description: The burgeoning trade partnership between China and Pakistan has brought about a rapidly expanding interest in learning Chinese as a foreign language. In order to equip its graduates to be able to contribute in the globalizing world, universities offer opportunities for learning foreign languages. In the same way, Karachi University's recently established Confucius Institute, which offers Chinese language learning opportunities, can be seen as not only a step forward in the internationalization of university education but also a means to create a bridge for intercultural communication. At the same time, the inclusion of Chinese language in the university's curriculum is driven by political and economic factors (Worton, 2009). Defining the current importance given to Chinese language learning, Bianco (2011:xiii) states Chinese as the 'gigantic up-and-comer.'
 In order to explore further the socio-political, economic and linguistic motivation for the promotion of Chinese language learning opportunities, I conducted a critical discourse analysis of policy documents, media reports, stakeholder's speeches, and website news. Initial findings suggest that cooperation, brotherhood and historical ties play a key role in immediate acceptance of Chinese language initiatives in Pakistan. Drawing inspiration from Fairclough's work on Language & Power (1989), a conscious look at the recurrent themes in these recent texts, gave me an insight into the background of relations between China and Pakistan and how language is used to foster the continuation of that historic bond.

description: Chersaecia densegyrata sp. nov.
urn:lsid:zoobank.org:act: 9468E60C-F711-46B3-8BD5-E7983BC2E36F
Figs 7 C–D, 8A
Diagnosis
A small, dextral, flat species with 6.5 slowly increasing whorls. Parietal wall with a single lamella, main plica free from lamella and apertural fold; intermediate plica attached to lower end of lamella. On the palatal wall there are two vertical plicae, with one horizontal plica below and three above.
Etymology
The name “ densegyrata ” refers to the rapidly increasing whorls of the new species.
Material examined
Holotype THAILAND: 1 shell, Chiang Mae Province, 20 km SSW of Ban Mae Khi, 19°34′40″ N, 99°4′52″ E, 700 m a.s.l., 22 Jun. 1987, F.G. Thompson leg. (UF 347223).
Description
SHELL. Dextral, white and light-brown striped; concave above, only protoconch protrudes above dorsal surface; protoconch consists of 2.5 whorls, first ca 1.5 whorls almost smooth with very small tubercles, remaining ones irregularly ribbed; entire shell with 6.5 whorls, slowly increasing, separated by rather deep suture, but dorsal surface of whorls flat; teleoconch finely decussated with low riblets and spiral lines; aperture relatively small; peristome strongly thickened and slightly reflected; parietal callus elevated, sharp, in contact with apertural fold, which is free from main plica; periumbilical area (ventral shell side around funnel-shaped umbilicus) nearly smooth.
Parietal wall with short vertical lamella, and intermediate plica, connected to lower end of lamella; main plica long, free from lamella and apertural fold. Palatal wall with six plicae, with second being longest; first, second, third and last plicae straight and horizontal; fourth and fifth vertical.
MEASUREMENTS (in mm). D = 13.5, H = 5 (holotype).
Differential diagnosis
Chersaecia densegyrata sp. nov. is similar to C. dextrorsa and C. reversalis sp. nov. in terms of coiling direction, but it is smaller and much flatter than the latter two species, and has rapidly-increasing whorls. There are also differences in the plication: the intermediate plica of C. dextrorsa and C. reversalis sp. nov. extends beyond the lamella in posterior direction, whereas it stops when reaching the lamella in the new species. Furthermore, the fourth and fifth palatal plicae of C. densegyrata sp. nov. are vertical.
Distribution
The new species is known from the type locality only.

description: We consider a spatially periodic (cosine) potential as a model for a crystalline solid that interacts with a harmonically oscillating external electric field. This problem is periodic both in space and time and can be solved analytically using the Kramers-Henneberger co-moving frame. By analyzing the stability of the closely related Mathieu-type differential equation, the electronic band structure can be obtained. We demonstrate that by changing the field intensity, the width of the zero-field band gaps can be drastically modified, including the special case when the external field causes the band gaps to disappear

description: We explain that supersymmetric attractors in general have several critical points due to the algebraic nature of the stabilization equations. We show that the critical values of the cosmological constant of the adS_5 vacua are given by the topological (moduli independent) formulae analogous to the entropy of the d=5 supersymmetric black holes. We present conditions under which more than one critical point is available (for black hole entropy as well as to the cosmological constant) so that the system tends to its own locally stable attractor point. We have found several families of Z_2-symmetric critical points where the central charge has equal absolute values but opposite signs in two attractor points. We present examples of interpolating solutions and discuss their generic features.

description: How rivers restored for aquatic biota such as Pacific Salmon (Oncorhynchus spp.) will evolve under shifting management and climate regimes is unknown. To inform this, we tracked the evolution of a highly impacted, regulated river reach following habitat restoration and subsequent drought and flood hydrology using a suite of data to better understand how created habitat evolves over time. Topographic change detection, riffle creation and persistence, substrate, and Chinook Salmon spawning and rearing habitat were evaluated for the three epochs. Sediment transport regimes and velocity outputs from the numerical flow model were used to interpret channel change associated with the flood season the site experienced. Salmon spawning observations and habitat suitability modeling demonstrated that habitat improved following restoration for both salmon spawning and rearing. Chinook Salmon spawning activity and the relative site utilization compared to escapement increased post Project. These benefits were largely maintained during drought and flood events, despite an absence of upstream coarse sediment supply. We hypothesize this was because the restoration design incorporated riffle-pool maintenance theories and the use of emergent islands that served as a local sediment source. Extrapolations of bioturbation by spawners suggest that if population targets for the river are met, topographic change due to spawning activity could exceed that caused by river flow under drought conditions and provide a modest contribution during flood years. Thus, this study demonstrates that river restoration can not only improve physical habitat, but also engage ecosystem engineers such as spawning salmonids to contribute to future habitat evolution.

description: In the present paper the ground state of a double orbitally degenerate model at weak intra-atomic interaction is studied using the Green functions method. Beside the diagonal matrix elements of electron-electron interactions the model includes correlated hopping integrals and inter-atomic exchange interaction. The influence of orbital degeneracy with Hund's rule coupling, correlated hopping and inter-atomic direct exchange on the ferromagnetic ordering is investigated. The expressions for ground state energy and magnetization, the criterion of transition from paramagnetic to ferromagnetic ground state as functions of the model parameters are obtained. The obtained results are compared with some experimental data for magnetic materials.

description: In this Letter, we consider a neutral system of mobile positive and negative charges confined on the surface of curved films. This may be an appropriate model for: i) a highly charged membrane whose counterions are confined to a sheath near its surface; ii) a membrane composed of an equimolar mixture of anionic and cationic surfactants in aqueous solution. We find that the charge fluctuations contribute a non-analytic term to the bending rigidity that varies logarithmically with the radius of curvature. This may lead to spontaneous vesicle formation, which is indeed observed in similar systems.

description: Devasthal Optical Telescope Integral Field Spectrograph (DOTIFS) is a new multi-object Integral Field Spectrograph (IFS) being designed and fabricated by the Inter-University Center for Astronomy and Astrophysics (IUCAA), Pune, India, for the Cassegrain side port of the 3.6m Devasthal Optical Telescope, (DOT) being constructed by the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital. It is mainly designed to study the physics and kinematics of the ionized gas, star formation and H II regions in the nearby galaxies. It is a novel instrument in terms of multi-IFU, built in deployment system, and high throughput. It consists of one magnifier, 16 integral field units (IFUs), and 8 spectrographs. Each IFU is comprised of a microlens array and optical fibers and has 7.4'' x 8.7'' field of view with 144 spaxel elements, each sampling 0.8'' hexagonal aperture. The IFUs can be distributed on the telescope side port over an 8' diameter focal plane by the deployment system. Optical fibers deliver light from the IFUs to the spectrographs. Eight identical, all refractive, dedicated spectrographs will produce 2,304 R~1800 spectra over 370-740nm wavelength range with a single exposure. Volume Phase Holographic gratings are chosen to make smaller optics and get high throughput. The total throughput of the instrument including the telescope is predicted as 27.5% on average. Observing techniques, data simulator and reduction software are also under development. Currently, conceptual and baseline design review has been done. Some of the components have already been procured. The instrument is expected to see its first light in 2016.

description: Ο σκοπός της εργασίας είναι η ανάπτυξη μιας εφαρμογής για την λήψη, αποθήκευση και προβολή ιχνών πολιτικών αεροσκαφών στην Πολεμική Αεροπορία (ΠΑ). Καθώς δεν είναι διαθέσιμα πραγματικά δεδομένα, η λήψη θα γίνεται από έναν εξομοιωτή - γεννήτρια ιχνών. Η αποθήκευση θα γίνεται σε μια γεωχωρική βάση δεδομένων με σκοπό τη δυνατότητα μελλοντικής επιχειρησιακής αξιοποίησης των δεδομένων. Η προβολή θα είναι περιορισμένη σε αεροπορική εικόνα πραγματικού χρόνου, αλλά και κάποιας ορισμένης στιγμής στο παρελθόν. Η ΠΑ διαθέτει ένα πλήθος radar για την ανίχνευση αεροσκαφών στον εναέριο χώρο της Ελλάδας, που συνοδεύεται από το ανάλογο λογισμικό για την παρουσίαση των δεδομένων που συλλέγονται. Στα κέντρα επιχειρήσεων όμως είναι εξαιρετικά χρήσιμο να υπάρχει διαθέσιμη και η αεροπορική εικόνα που διαθέτει η Υπηρεσία Πολιτικής Αεροπορίας (ΥΠΑ), και κατά συνέπεια το ευρύ κοινό, για επιχειρησιακούς σκοπούς. Το λογισμικό που χρησιμοποιείται αυτή τη στιγμή για το σκοπό αυτό, δεν έχει τη δυνατότητα αποθήκευσης των ιχνών. Το κενό αυτό θα προσπαθήσει να καλύψει η παρούσα εργασία.
description: The scope of this thesis is the development of an application that will receive, store and present civil aviation aircraft tracks for the Hellenic Air Force (HAF). Since real data is not available, the application will receive tracks from a simulator - generator of aircraft tracks. The tracks will be stored in a geospatial database so they can be used in the future by HAF. The presentation will be limited in displaying real and past time data to the user, with no further analysis. HAF has a number of radars tracking aircraft in the Greek airspace, accompanied by software capable of presenting the data collected. In operations centers though, is it invaluable to have available the airspace status as the Hellenic Civil Aviation Authority (HCAA) sees it, which is how the general public sees it. The software currently being used for that purpose does not have the capability of storing the data collected in any format. It is exactly this capability that the development of this thesis’ application will attempt to implement.
Thermodynamics of $f(R)$ Gravity with Disformal Transformation

description: We study thermodynamics in $f(R)$ gravity with the disformal transformation. The transformation applied to the matter Lagrangian has the form of $\g_{\m\n} = A(ϕ,X)g_{\m\n} + B(ϕ,X)\pa_\m\f\pa_\n\f$ with the assumption of the Minkowski matter metric $\g_{\m\n} = \e_{\m\n}$, where $ϕ$ is the disformal scalar and $X$ is the corresponding kinetic term of $ϕ$. We verify the generalized first and second laws of thermodynamics in this disformal type of $f(R)$ gravity in the Friedmann-Lemaître-Robertson-Walker (FLRW) universe. In addition, we show that the Hubble parameter contains the disformally induced terms, which define the effectively varying equations of state for matter.

Rotational invariance and order-parameter stiffness in frustrated quantum spin systems

description: We compute, within the Schwinger-boson scheme, the Gaussian-fluctuation corrections to the order-parameter stiffness of two frustrated quantum spin systems: the triangular-lattice Heisenberg antiferromagnet and the J1-J2 model on the square lattice. For the triangular-lattice Heisenberg antiferromagnet we found that the corrections weaken the stiffness, but the ground state of the system remains ordered in the classical 120 spiral pattern. In the case of the J1-J2 model, with increasing frustration the stiffness is reduced until it vanishes, leaving a small window 0.53 < J2/J1 < 0.64 where the system has no long-range magnetic order. In addition, we discuss several methodological questions related to the Schwinger-boson approach. In particular, we show that the consideration of finite clusters which require twisted boundary conditions to fit the infinite-lattice magnetic order avoids the use of ad hoc factors to correct the Schwinger-boson predictions.

description: Using mainly two techniques, a point transformation and a time dependent supersymmetry, we construct in sequence several quantum infinite potential wells with a moving barrier. We depart from the well known system of a one-dimensional particle in a box. With a point transformation, an infinite square-well potential with a moving barrier is generated. Using time dependent supersymmetry, the latter leads to a trigonometric Pöschl-Teller potential with a moving barrier. Finally, a confluent time dependent supersymmetry transformation is implemented to generate new infinite potential wells, all of them with a moving barrier. For all systems, solutions of the corresponding time dependent Schrödinger equation fulfilling boundary conditions are presented in a closed form.
A numerical study of the r-mode instability of rapidly rotating nascent neutron stars

description: The first results of numerical analysis of classical r-modes of {\it rapidly} rotating compressible stellar models are reported. The full set of linear perturbation equations of rotating stars in Newtonian gravity are numerically solved without the slow rotation approximation. A critical curve of gravitational wave emission induced instability which restricts the rotational frequencies of hot young neutron stars is obtained. Taking the standard cooling mechanisms of neutron stars into account, we also show the `evolutionary curves' along which neutron stars are supposed to evolve as cooling and spinning-down proceed. Rotational frequencies of $1.4M_{\odot}$ stars suffering from this instability decrease to around 100Hz when the standard cooling mechanism of neutron stars is employed. This result confirms the results of other authors who adopted the slow rotation approximation.

Research on Electronic Dental Records: A Scope Review

subject: FOS: Clinical medicine

description: The medical records are records responsible for containing the patient's personal and clinical data, in Dentistry both forms are used, both paper and electronic, however, it is possible to observe the replacement of the physical by the digital. This study aimed to evaluate the aspects and understand the importance of using Electronic Dental Records. The bibliographic search took place in March 2021, in the following databases: Medline/PubMed, LILACS, Scopus, Web of Science, and as gray literature, the first 100 articles in Academic Google. The guiding question was based on the PCC acronym (Population/Concept/Context), the PRISMA guidelines were followed in the writing development process. The descriptors used were: “Electronic Health Records” and “Dentistry, indexed in Mesh, used without language restriction in the research, Mendely and Rayyan were also used to filter the articles. Thus, 3,065 publications were initially found, after reading the titles and abstracts and analyzing the duplicate studies, 3,015 were excluded, thus 32 articles became eligible, of which, after accessing the full texts, only remained 9 to be included in the study according to the answer guided by the initial question. Countries that have a greater technological support, such as the USA, have more common use of electronic medical records, and it is possible to observe the benefits and harms of using this category of record. Software requires greater attention to its handling and costing, having a greater financial impact, in addition, there is a risk of exposure of patient data.
SOFIA mid-infrared observations of Supernova 1987A in 2016 --- forward shocks and possible dust re-formation in the post-shocked region?

description: The equatorial ring of Supernova (SN) 1987A has been exposed to forward shocks from the SN blast wave, and it has been suggested that these forward shocks have been causing on-going destruction of dust in the ring. We obtained SOFIA FORCAST 11.1, 19.7 and 31.5 micron photometry of SN\,1987A in 2016. Compared with Spitzer measurements 10 years earlier, the 31.5 micron flux has significantly increased. The excess at 31.5 micron appears to be related to the Herschel 70 micron excess, which was detected 5 years earlier. The dust mass needed to account for the the 31.5--70 micron excess is 3--7x10^-4 Msun, more than ten times larger than the ring dust mass (1x10^-5 Msun) estimate from the data 10-years earlier. We argue that dust grains are re-formed or grown in the post-shock regions in the ring after forward shocks have destroyed pre-existing dust grains in the ring and released refractory elements into gas. In the post-shock region, atoms can stick to surviving dust grains, and the dust mass may have increased (grain growth), or dust grains might have condensed directly from the gas. An alternative possibility is that the outer part of the expanding ejecta dust might have been heated by X-ray emission from the circumstellar ring. The future development of this excess could reveal whether grains are reformed in the post-shocked region of the ring or eject dust is heated by X-ray.
