Time-dependent shock acceleration of particles. Effect of the time-dependent injection, with application to supernova remnants

description: Three approaches are considered to solve the equation which describes the time-dependent diffusive shock acceleration of test particles at the non-relativistic shocks. At first, the solution of Drury (1983) for the particle distribution function at the shock is generalized to any relation between the acceleration time-scales upstream and downstream and for the time-dependent injection efficiency. Three alternative solutions for the spatial dependence of the distribution function are derived. Then, the two other approaches to solve the time-dependent equation are presented, one of which does not require the Laplace transform. At the end, our more general solution is discussed, with a particular attention to the time-dependent injection in supernova remnants. It is shown that, comparing to the case with the dominant upstream acceleration time-scale, the maximum momentum of accelerated particles shifts toward the smaller momenta with increase of the downstream acceleration time-scale. The time-dependent injection affects the shape of the particle spectrum. In particular, i) the power-law index is not solely determined by the shock compression, in contrast to the stationary solution; ii) the larger the injection efficiency during the first decades after the supernova explosion, the harder the particle spectrum around the high-energy cutoff at the later times. This is important, in particular, for interpretation of the radio and gamma-ray observations of supernova remnants, as demonstrated on a number of examples.

CENTRAL LIMIT THEORY FOR COMBINED CROSS SECTION AND TIME SERIES WITH AN APPLICATION TO AGGREGATE PRODUCTIVITY SHOCKS

Publisher: name: Cambridge University Press
Year: 2022

description: Combining cross-sectional and time-series data is a long and well-established practice in empirical economics. We develop a central limit theory that explicitly accounts for possible dependence between the two datasets. We focus on common factors as the mechanism behind this dependence. Using our central limit theorem (CLT), we establish the asymptotic properties of parameter estimates of a general class of models based on a combination of cross-sectional and time-series data, recognizing the interdependence between the two data sources in the presence of aggregate shocks. Despite the complicated nature of the analysis required to formulate the joint CLT, it is straightforward to implement the resulting parameter limiting distributions due to a formal similarity of our approximations with Murphy and Topel’s (1985, Journal of Business and Economic Statistics 3, 370–379) formula.

description: Mass loss is one of the key parameters that determine stellar evolution. Despite the progress we have achieved over the last decades we still cannot match the observational derived values with theoretical predictions. Even worse, there are certain phases, such as the B[e] supergiants (B[e]SGs) and the Luminous Blue Variables (LBVs), where significant mass is lost through episodic or outburst activity. This leads to various structures forming around them that permit dust formation, making these objects bright IR sources. The ASSESS project aims to determine the role of episodic mass in the evolution of massive stars, by examining large numbers of cool and hot objects (such as B[e]SGs/LBVs). For this purpose, we initiated a large observation campaign to obtain spectroscopic data for ∼ 1000 IR-selected sources in 27 nearby galaxies. Within this project we successfully identified seven B[e] supergiants (one candidate) and four Luminous Blue Variables of which six and two, respectively, are new discoveries. We used spectroscopic, photometric, and light curve information to better constrain the nature of the reported objects. We particularly noted the presence of B[e]SGs at metallicity environments as low as 0.14 Z☉.

description: Economists have for decades recommended that carbon dioxide and other greenhouse gases be taxed – or otherwise priced – to provide incentives for their reduction. The USA does not have a federal carbon tax; however, many state and federal programs to reduce carbon emissions effectively price carbon – for example, through cap-and-trade systems or regulations. There are also programs that subsidize reductions in carbon emissions. At the 2022 meetings of the American Economic Association, the Society for Benefit-Cost Analysis brought together five well-known economists – Joe Aldy, Dallas Burtraw, Carolyn Fischer, Meredith Fowlie, and Rob Williams – to discuss how the USA does, in fact, price carbon and how it could price carbon. Maureen Cropper chaired the panel. This paper summarizes their remarks.

SIMULTANEOUS EQUATIONS MODELS WITH HIGHER-ORDER SPATIAL OR SOCIAL NETWORK INTERACTIONS

Publisher: name: Cambridge University Press
Year: 2022

description: This paper develops an estimation methodology for network data generated from a system of simultaneous equations, which allows for network interdependencies via spatial lags in the endogenous and exogenous variables, as well as in the disturbances. By allowing for higher-order spatial lags, our specification provides important flexibility in modeling network interactions. The estimation methodology builds, among others, on the two-step generalized method of moments estimation approach introduced in Kelejian and Prucha (1998, Journal of Real Estate Finance and Economics 17, 99–121; 1999, International Economic Review 40, 509–533; 2004, Journal of Econometrics 118, 27–50). The paper considers limited and full information estimators, and one- and two-step estimators, and establishes their asymptotic properties. In contrast to some of the earlier two-step estimation literature, our asymptotic results facilitate joint tests for the absence of all forms of network spillovers.

Being pragmatic about syntactic bootstrapping

syntactic bootstrapping

description: Words have meanings vastly undetermined by the contexts in which they occur. Their acquisition therefore presents formidable problems of induction. Lila Gleitman and colleagues have advocated for one part of a solution: indirect evidence for a word’s meaning may come from its syntactic distribution, via SYNTACTIC BOOTSTRAPPING. But while formal theories argue for principled links between meaning and syntax, actual syntactic evidence about meaning is noisy and highly abstract. This paper examines the role that syntactic bootstrapping can play in learning modal and attitude verb meanings, for which the physical context is especially uninformative. I argue that abstract syntactic classifications are useful to the child, but that something further is both necessary and available. I examine how pragmatic and syntactic cues can combine in mutually constraining ways to help learners infer attitude meanings, but need to be supplemented by semantic information from the lexical context in the case of modals.

The role of internal constraints and stylistic congruence on a variant's social impact

description: In natural conversation, multiple factors likely impact the social force of a sociolinguistic variant, yet researchers have tended to examine individual factors in isolation. This paper considers two underexamined factors together—the role of a variable's internal constraints and the role of stylistically congruent surrounding speech—to understand their combined influence on how a single variable's realization is socially interpreted. Focusing on English variable (ING), two accent rating experiments used stimuli varying the grammatical category of (ING) words and varying the stylistic congruence (natural sentences versus spliced stimuli) between (ING) realization and sentence frames. Results indicate that listeners showed sensitivity to (ING)'s internal constraints but only when the congruence between (ING)'s realization and other cues was not disrupted by using spliced stimuli. These findings suggest that internal constraints and stylistic congruence play a role in social signaling, and have methodological implications for the use of splicing.
Monitoring Electrostatically-Induced Deflection, Strain and Doping in Suspended Graphene using Raman Spectroscopy

description: Electrostatic gating offers elegant ways to simultaneously strain and dope atomically thin membranes. Here, we report on a detailed \textit{in situ} Raman scattering study on graphene, suspended over a Si/SiO$_2$ substrate. In such a layered structure, the intensity of the Raman G- and 2D-mode features of graphene are strongly modulated by optical interference effects and allow an accurate determination of the electrostatically-induced membrane deflection, up to irreversible collapse. The membrane deflection is successfully described by an electromechanical model, which we also use to provide useful guidelines for device engineering. In addition, electrostatically-induced tensile strain is determined by examining the softening of the Raman features. Due to a small residual charge inhomogeneity $\sim 5\times 10^{10}~\rm cm^{-2}$, we find that non-adiabatic anomalous phonon softening is negligible compared to strain-induced phonon softening. These results open perspectives for innovative Raman scattering-based readout schemes in two-dimensional nanoreso
Mapping the space of quasisymmetric stellarators using optimized near-axis expansion

description: A method is demonstrated to rapidly calculate the shapes and properties of quasi-axisymmetric and quasi-helically symmetric stellarators. In this approach, optimization is applied to the equations of magnetohydrodynamic equilibrium and quasisymmetry, expanded in the small distance from the magnetic axis, as formulated by Garren & Boozer [Phys. Fluids B, vol. 3, 1991, p. 2805]. Due to the reduction of the equations by the expansion, the computational cost is significantly reduced, to times of the order of 1 cpu second, enabling wide and high-resolution scans over parameter space. In contrast to traditional stellarator optimization, here, the cost function serves to maximize the volume in which the expansion is accurate. A key term in the cost function is ∥∇B∥ , the norm of the magnetic field gradient, to maximize scale lengths in the field. Using this method, a database of 5×105 optimized configurations is calculated and presented. Quasisymmetric configurations are observed to exist in continuous bands, varying in the ratio of the magnetic axis length to average major radius. Several qualitatively new types of configuration are found, including quasi-helically symmetric fields in which the number of field periods is two or more than six.

description: School represents an important context for children’s social, moral, and identity development. Research indicates that supportive teacher-student relationships are significantly related to positive student academic achievement. Unfortunately, teacher bias as well as peer exclusion based on group identity (gender, race, ethnicity, and nationality) pervade many school contexts. The presence of these biases in the classroom is negatively related to students’ academic development, especially for children who are minoritized and marginalized. Very little research has connected teacher bias and children’s reasoning about bias and inequalities in the classroom context. The classroom is a complex environment in which to examine children’s social and moral reasoning about bias, given teachers’ position of authority which often includes power, status, and prestige. We propose that understanding both teacher bias and peer intergroup exclusion are essential for promoting more fair classrooms. This paper reviews foundational theory as well as the social reasoning developmental model as a framework for studying how children think about fairness and bias in the classroom context. We then discuss current research on children’s social-cognitive and moral capacities, particularly in the contexts of societal inequality and social inclusion or exclusion. Finally, this article proposes new directions for research to promote fairness and inclusivity in schools and suggests how these new lines of research might inform school-based interventions.

description: This work relates to the occurrence and crystal-chemical characterization of fibrous erionite, a carcinogenic zeolite, discovered for the first time in the volcanic rocks of Latium, Italy. The erionite samples were investigated using SEM, TGA, PXRD, FTIR and Raman spectroscopies. Cell parameters, fractional coordinates and site scattering were refined using the Rietveld method. Two different types of erionite were found, having different crystal morphologies, chemical composition, and structure. The first type is an extremely fibrous erionite-K, with Si/(Si+Al) ratio of 0.77, cell parameters a=13.255 Å, c=15.053 Å and cell volume V=2290.49 Å3. The second type is acicular to highly fibrous erionite-Na, with a lower Si/(Si+Al) ratio (0.72-0.73) and larger cell parameters (a=13.291 Å, c=15.146 Å, cell volume V=2317.35 Å3). Both erionite types occur as fibers of inhalable size. The structure of both samples, refined by the Rietveld method on powder X-ray diffraction data, collected in transmission mode on capillaries, is consistent with that of samples with similar extra-framework cations content. Raman and FTIR data are presented and discussed. The described finding of potentially carcinogenic erionite in the volcanic rocks of Latium that are typically rich in zeolites of various nature, both as cavity filling and devitrification products of glass, suggests that this hazardous mineral might be more common than previously believed in the area and points to the need for detailed and more systematic studies.

Development of automaticity in processing L2 collocations: The roles of L1 collocational knowledge and practice condition

Publisher: name: Cambridge University Press
Year: 2023

description: This study examined the development of automaticity in processing L2 collocations, and the roles of L1 collocational knowledge and practice conditions in the development process. Korean learners of English were assigned to one of two practice conditions (practice in identical or varied contexts). The learning gains for word combinations with and without equivalent counterparts in the L1 (L1-only and L2-only collocations) were assessed using response times (RTs) and coefficients of variation (CV) from a phrasal decision task. The results demonstrated that the learners in both groups showed significantly improved collocation processing for both types of items in terms of speed (RT) and automaticity (CV) over time. The RT and CV analyses indicated that both groups’ improvements in collocation processing in the later stages of learning were associated with automatization. Interestingly, L1 collocational knowledge played a facilitative role in processing speed only in the early stages of learning. No reliable evidence for the differential effects of the two types of practice conditions on developing automaticity in collocation processing was found.

description: Several nonclassical effects displayed by wave packets subject to generic nonlinear Hamiltonians can be identified and assessed directly from tomograms without attempting to reconstruct the Wigner function or the density matrix explicitly. We have demonstrated this for both single-mode and bipartite systems. We have shown that a wide spectrum of effects such as the revival phenomena, quadrature squeezing and Hong-Mandel and Hillery type higher-order squeezing in both the single-mode system and the double-well Bose-Einstein condensate can be obtained from appropriate tomograms in a straightforward manner. We have investigated entropic squeezing of the subsystem state of a bipartite system as it evolves in time, solely from tomograms. Further we have identified a quantifier of the extent of entanglement between subsystems which can be readily obtained from the tomogram and which mirrors the qualitative behavior of other measures of entanglement such as the subsystem von Neumann entropy and the subsystem linear entropy. The procedures that we have demonstrated can be readily adapted to multimode systems.

description: This paper examines the role of family in the process of labor control on large-scale vegetable farm in China by looking to their everyday life. In doing so, I spent two weeks in summer 2019 on the vegetable farm to do participant observation, and also did follow-up semi-structured interviews with both the manager of the farm and 11 households both face-to-face and through online apps. To begin with, I explore the formation of this form of family migration, which are found that the presence of family is not at the behest of the boss, but rather a result from the subcontracting system and a rational choice related to the family cycle. Then, by looking into their gender division of household labor, I found that economic independence did not alleviate wives’ burden on doing housework; rather, most of the wives were captured in the “double shifts”, where they performed at home in addition to the paid work performed in the labor market. I further argue that even for those husbands who are willing to help with certain type of housework, it is largely a pragmatic solution rather than an ideological transformation of the gender norm, which, in turn, does favor to the farm owner. Last, I argue that instead of distracting the farmworkers, the presence of family indeed does benefit to the farm owners by playing an important role in the process of labor control, in terms of preventing shirking in the pre-harvest stage and lowering their mobility in the peak seasons. In this specific case of corporate farm, the conspiracy of “capitalism and patriarchy” was found.

description: The ProByFish study was initiated to assist in the development of methods to evaluate the impact of different fisheries management options on the objectives of the Common Fisheries Policy (CFP). The study developed robust methods to a) define target and bycatch species and b) to divide the bycatch species into valuable and collateral bycatch species, the first generally retained on board and landed and the latter generally discarded. The classification of a species depended on the fleet and area in which the fleet operates. The study also identified species which can only sustain low levers of fishing and proceeded to include examples of these in mixed fisheries models. This report describes the work under the study to analyse of effect of TACs for target species on fishing mortalities of hybrid, valued and collateral bycatch species assuming different management strategies to define TACs for the target species, while no management applies on the bycatch species. The analyses were conducted in a mixed fisheries Management Strategy Evaluation (MSE) framework to examine the probability that single stock TACs are sufficient under natural variability, mixed fishery dynamics and management strategies. The result shows that the effect of changing the species on which to define a TAC are minor compared to the effects concerning the uncertainty around the implementation of the landing obligation.

description: Within the many different models that appeared with the use of cold atoms to design BECs the bubble trap shaped potential has been of great interest. For the anisotropic bubble trap physics in the thin-shell limit the relationship between the physical parameters and the resulting manifold geometry is yet to be fully understood. In this paper, we work towards this goal showing how the parameters of the system must be manipulated in order to allow for a non-collapsing thin-shell limit. In such a limit, a dimensional compactification takes place thus leading to an effective 2D Hamiltonian which relates to up-to-date bubble trap experiments. At last, our Hamiltonian is pertubatively solved for some particular cases as applications of our theory.

description: We introduce the Non-commutative Subset Convolution - a convolution of functions useful when working with determinant-based algorithms. In order to compute it efficiently, we take advantage of Clifford algebras, a generalization of quaternions used mainly in the quantum field theory. We apply this tool to speed up algorithms counting subgraphs parameterized by the treewidth of a graph. We present an $O^*((2^ω+ 1)^{tw})$-time algorithm for counting Steiner trees and an $O^*((2^ω+ 2)^{tw})$-time algorithm for counting Hamiltonian cycles, both of which improve the previously known upper bounds. The result for Steiner Tree also translates into a deterministic algorithm for Feedback Vertex Set. All of these constitute the best known running times of deterministic algorithms for decision versions of these problems and they match the best obtained running times for pathwidth parameterization under assumption $ω= 2$.

The Competing Hegemony of Developing Sustainable Private Vehicles: An Ethnographic Analysis of Friction Between China’s Conventional and Electric Vehicles’ Cultural Values

description: This ethnographic study examines the causes and consequences of frictions produced during the value-making process of Chinese electric and conventional vehicle supporters. Previous scholars such as Gökçe Günel (2019) revealed that the tensions created by heterogeneous views shape the ideologies of smart urban spaces. Here I elaborated on Günel (2019)’s argument by borrowing Anna Tsing (2011)’s concept of “friction” throughout the analysis to strengthen how tensions created by the heterogeneous views produce competing hegemony that makes creativities invisible. I identified five technical and sentimental values related to China’s private automobiles. The five values in this study are Intelligence (technical), Mechanical Structure (technical), Nostalgia (sentimental), Progressive Nationalism (sentimental), and Environmentalism (technical & sentimental). I examined how social cohesions are formed to develop competing hegemony based on the ways that electric and conventional vehicle supporters categorize the properties of these values. Finally, I argue that in order to achieve the production of sustainable private automobiles in China, the automobile industries and interest parties need to seek collaboration through acknowledging the friction and negotiating the conflicts.
The Timescale-Dependent Color Variability of Quasars Viewed with GALEX

description: In recent work done by Sun et. al., the color variation of quasars, namely the bluer-when-brighter trend, was found to be timescale-dependent using SDSS $g/r$ band light curves in the Stripe 82. Such timescale dependence, i.e., bluer variation at shorter timescales, supports the thermal fluctuation origin of the UV/optical variation in quasars, and can be well modeled with the inhomogeneous accretion disk model. In this paper, we extend the study to much shorter wavelengths in the rest frame (down to extreme UV), using GALaxy Evolution eXplorer (GALEX) photometric data of quasars collected in two ultraviolet bands (near-UV and far-UV). We develop Monte-Carlo simulations to correct possible biases due to the considerably larger photometric uncertainties in GALEX light curves (particularly in far-UV, comparing with SDSS $g/r$ bands), which otherwise could produce artificial results. We securely confirm the previously discovered timescale dependence of the color variability with independent datasets and at shorter wavelengths. We further find the slope of the correlation between the amplitude of color variation and timescale however appears even steeper than that predicted by the inhomogeneous disk model, which assumes that disk fluctuations follow damped random walk process. In line with the much flatter structure function observed in far-UV comparing with that at longer wavelengths, this implies deviation from DRW process in the inner disk where rest frame extreme UV radiation is produced.

description: Space division multiplexing using multicore fibers is becoming a more and more promising technology. In space-division multiplexing fiber network, the reconfigurable switch is one of the most critical components in network nodes. In this paper we for the first time demonstrate reconfigurable space-division multiplexing switching using silicon photonic integrated circuit, which is fabricated on a novel silicon-on-insulator platform with buried Al mirror. The silicon photonic integrated circuit is composed of a 7x7 switch and low loss grating coupler array based multicore fiber couplers. Thanks to the Al mirror, grating couplers with ultra-low coupling loss with optical multicore fibers is achieved. The lowest total insertion loss of the silicon integrated circuit is as low as 4.5 dB, with low crosstalk lower than -30 dB. Excellent performances in terms of low insertion loss and low crosstalk are obtained for the whole C-band. 1 Tb/s/core transmission over a 2-km 7-core fiber and space-division multiplexing switching is demonstrated successfully. Bit error rate performance below 10-9 is obtained for all spatial channels with low power penalty. The proposed design can be easily upgraded to reconfigurable optical add/drop multiplexer capable of switching several multicore fibers.
