description: Perovskite oxynitrides are, due to their reduced band gap compared to oxides, promising materials for photocatalytic applications. They are most commonly synthesized from {110} layered Carpy-Galy (A$_2$B$_2$O$_7$}) perovskites via thermal ammonolysis, i.e. the exposure to a flow of ammonia at elevated temperature. The conversion of the layered oxide to the non-layered oxynitride must involve a complex combination of nitrogen incorporation, oxygen removal and ultimately structural transition by elimination of the interlayer shear plane. Despite the process being commonly used, little is known about the microscopic mechanisms and hence factors that could ease the conversion. Here we aim to derive such insights via density functional theory calculations of the defect chemistry of the oxide and the oxynitride as well as the oxide's surface chemistry. Our results point to the crucial role of surface oxygen vacancies in forming clusters of NH$_3$ decomposition products and in incorporating N, most favorably substitutionally at the anion site. N then spontaneously diffuses away from the surface, more easily parallel to the surface and in interlayer regions, while diffusion perpendicular to the interlayer plane is somewhat slower. Once incorporation and diffusion lead to a local N concentration of about 70% of the stoichiometric oxynitride composition, the nitridated oxide spontaneously transforms to a nitrogen-deficient oxynitride.

description: Given the model of partial dependence between accounting and taxation, the nominal tax rate tells nothing about the tax burden borne by companies`. Therefore, the effective tax rate is, an indicator to be considered by stakeholders when making decisions once it represents the tax burden that the company bears during the period. This paper aims to present a brief literature review on the effective corporate tax rate, emphasizing its determinants, namely the size, the leverage, the capital intensity, the stock intensity, and the return on assets. With this paper, there was detected evidence of a significant relationship between the effective tax rate and the determinants analysed.

description: The favorable climatic condition, the vast irrigation sources, the abundant labor and other factors of Ethiopia are viable for the production and processing of tomato and other fruits. The present study has been initiated to evaluate the existing manufacturing process, and test the suitability of three tomato varieties for juice and sauce production. This helped to see the technological advantages for the production of good quality products. Samples products in triplicate from each variety Bergad juice (BJ1, BJ2, BJ3), Miya juice (MJ1, MJ2, MJ3), Chali juice (CJ1, CJ2, CJ3), Bergad sauce (BS1, BS2, BS3), Miya sauce (MS1, MS2, MS3), and Chali sauce (CS1, CS2, CS3) were prepared and analyzed for their physicochemical characteristics. They were determined following standard methods. Texture was analyzed according to TA-plus NEXYGEN manual. Color was determined by LOVIBOND 3000 color comparator. Titration methods by 0.1N sodium hydroxide and phenolphthalein indicator were used for the determination of acidity. Abbe type refractometer was used at a temperature of 230C for TSS. The process parameters at Merti Agro-Processing plant were evaluated to test the suitability of improved varieties. The data obtained from the laboratory analysis were subjected to ANOVA using SPSS software. Bergad (Merti Variety) was used as a control. Means were then compared at 5% significance level. The results showed that Juices of improved varieties were not significantly different from the control in acidity and color. In fact, they registered high TSS than that of the control. The Flavor of Chali juice was preferred most and was not significantly different from the control. However there is a significant difference in NTSS, Miya and Chali scoring higher means but all sauces are not significantly different in acidity. Based on the findings a tomato juice manufacturing plant has been suggested that Miya variety can be used for both juice and sauce production, while Chali can be used only for sauce production.

description: We study the emission spectrum of two distant qubits strongly coupled to a waveguide by using the numerical and analytical approaches, which are beyond the Markovian approximation and the rotating-wave approximation (RWA). The numerical approach combines the Dirac-Frenkel time-dependent variational principle with the multiple Davydov $D_{1}$ ansatz. A transformed RWA (TRWA) treatment and a standard perturbation (SP) are used to analytically calculate the emission spectrum. It is found that the variational approach and the TRWA treatment yield accurate emission spectra of the two distant qubits in certain strong coupling regimes while the SP breaks down. The emission spectrum is found to be asymmetric irrespective of the two-qubit distance and exhibits a single peak, doublet, and multipeaks depending on the two-qubit distance as well as the initial states. In sharply contrast with the single-qubit case, the excited-state populations of the two qubits can ultraslowly decay due to the subradiance even in the presence of a strong qubit-waveguide coupling, which in turn yields ultranarrow emission line. Our results provide insights into the emission spectral features of the two distant qubits in the strong light-matter coupling regime.

description: We study the problem \begin{equation*} (I_ε) \left\{\begin{aligned} -Δu- \frac{μu}{|x|^2}&=u^p -εu^q \quad\text{in }\quad Ω, \\ u&>0 \quad\text{in }\quad Ω, \\ u &\in H^1_0(Ω)\cap L^{q+1}(Ω), \end{aligned} \right. \end{equation*} where $q>p\geq 2^*-1$, $ε>0$ is a parameter, $Ω\subseteq\mathbb{R}^N$ is a bounded domain with smooth boundary, $0\in Ω$, $N\geq 3$ and $0\frac{2+ν}ν$, where $ν=\sqrt{\barμ}-\sqrt{\barμ-μ}$. Moreover, we show that when $q=\frac{2+ν}ν$ and $u$ is radial, $u\sim |x|^{-ν}|\log|x||^{-\fracν{2}}$. This gives the complete classification of singularity at $0$ in the supercritical case. We also obtain gradient estimate. Using the transformation $v=|x|^νu$, we reduce the problem $(I_ε)$ to $(J_ε)$ \begin{equation*} (J_ε) \left\{\begin{aligned} -div(|x|^{-2ν} \nabla v)&=|x|^{-(p+1)ν} v^p -ε|x|^{-(q+1)ν} v^q \quad\text{in }\quad Ω, \\ v&>0 \quad\text{in }\quad Ω, \\ v& \in H^1_0(Ω, |x|^{-2ν} )\cap L^{q+1}(Ω, |x|^{-(q+1)ν} ), \end{aligned} \right. \end{equation*} and then formulating a variational problem for $(J_ε)$, we establish the existence of a variational solution $v_ε$. Furthermore, we characterize the asymptotic behavior of $v_ε$ as $ε\to 0$ by variational arguments and when $p=2^*-1$, we show how the solution $v_ε$ blows-up at $0$. This is the first paper where the results have been established with super critical exponents for $μ>0$.

description: This article is part of the reform initiated with the publication of the International Public Sector Accounting Standards (IPSAS), although limited to the accounting regulations applicable to the public sector in Cape Verde, with the objective of identifying the degree of implementation and adequacy of the applicable regulation in Cape Verde and the future perception of a possible reform to accounting IPSAS. Its development follows a qualitative methodology, essentially descriptive, with information collected using an interview survey, applied between October and December 2019, by e-mail, to senior technicians of the Public Administration of Cabo Verde. The results point to the existence of some weaknesses and inoperability, resulting from the current regulation, but which are due its low degree of its implementation and not to its inadequacy. They therefore suggest some improvements to update and generalize its implementation, but not a reform, as it has sufficient capacity to meet the needs of the Public Administration in Cape Verde.

description: The Central Molecular Zone (CMZ; the central ~ 500 pc of the Galaxy) is a kinematically unusual environment relative to the Galactic disc, with high velocity dispersions and a steep size-linewidth relation of the molecular clouds. In addition, the CMZ region has a significantly lower star formation rate (SFR) than expected by its large amount of dense gas. An important factor in explaining the low SFR is the turbulent state of the star-forming gas, which seems to be dominated by rotational modes. However, the turbulence driving mechanism remains unclear. In this work, we investigate how the Galactic gravitational potential affects the turbulence in CMZ clouds. We focus on the CMZ cloud G0.253+0.016 (`the Brick'), which is very quiescent and unlikely to be kinematically dominated by stellar feedback. We demonstrate that several kinematic properties of the Brick arise naturally in a cloud-scale hydrodynamics simulation that takes into account the Galactic gravitational potential. These properties include the line-of-sight velocity distribution, the steepened size-linewidth relation, and the predominantly solenoidal nature of the turbulence. Within the simulation, these properties result from the Galactic shear in combination with the cloud's gravitational collapse. This is a strong indication that the Galactic gravitational potential plays a crucial role in shaping the CMZ gas kinematics, and is a major contributor to suppressing the SFR by inducing predominantly solenoidal turbulent modes.

description: In this work, we show that collisions of one type of nonlinear wave can lead to generation of a different kind of nonlinear wave. Specifically, we demonstrate the formation of topological solitons (or transition waves) via collisions of elastic vector solitons, another type of nonlinear wave, in a multi-stable mechanical system with coupling between translational and rotational degrees of freedom. We experimentally observe the nucleation of a phase transformation arising from colliding waves, and we numerically investigate head-on and overtaking collisions of solitary waves with vectorial properties (i.e., elastic vector solitons). Unlike KdV-type solitons, which maintain their shape despite collisions, our system shows that collisions of two vector solitons can cause nucleation of a new phase via annihilation of the vector soltions, triggering the propagation of transition waves. The propagation of these depends both on the amount of energy carried by the vector solitons and on their respective rotational directions. The observation of the initiation of transition waves with collisions of vector solitons in multistable mechanical systems serves as an example of new fundamental nonlinear wave interactions, and could also prove useful in applications involving reconfigurable structures.

description: In this paper, we consider the transmit design for multi-input multi-output (MIMO) wiretap channel including a malicious jammer. We first transform the system model into the traditional three-node wiretap channel by whitening the interference at the legitimate user. Additionally, the eavesdropper channel state information (ECSI) may be fully or statistically known, even unknown to the transmitter. Hence, some strategies are proposed in terms of different levels of ECSI available to the transmitter in our paper. For the case of unknown ECSI, a target rate for the legitimate user is first specified. And then an inverse water-filling algorithm is put forward to find the optimal power allocation for each information symbol, with a stepwise search being used to adjust the spatial dimension allocated to artificial noise (AN) such that the target rate is achievable. As for the case of statistical ECSI, several simulated channels are randomly generated according to the distribution of ECSI. We show that the ergodic secrecy capacity can be approximated as the average secrecy capacity of these simulated channels. Through maximizing this average secrecy capacity, we can obtain a feasible power and spatial dimension allocation scheme by using one dimension search. Finally, numerical results reveal the effectiveness and computational efficiency of our algorithms.

description: We use time- and energy-resolved optical spectroscopy to investigate the coupling of electron-hole excitations to the magnetic environment in the relativistic Mott insulator Na$_2$IrO$_3$. We show that, on the picosecond timescale, the photoinjected electron-hole pairs delocalize on the hexagons of the Ir lattice via the formation of quasi-molecular orbital (QMO) excitations and the exchange of energy with the short-range-ordered zig-zag magnetic background. The possibility of mapping the magnetic dynamics, which is characterized by typical frequencies in the THz range, onto high-energy (1-2 eV) charge excitations provides a new platform to investigate, and possibly control, the dynamics of magnetic interactions in correlated materials with strong spin-orbit coupling, even in the presence of complex magnetic phases.

description: We have theoretically studied the field-strength dependent high-harmonic generation (HHG) in doped systems like nano-size or bulk materials. Our results show when the amplitude of the vector potential A_peak of the driving laser reaches the half-width of the Brillouin zone (π/a0), the harmonic yield of the undoped systems is larger than the doped systems. The band-climbing process enhances the interband transition of HHG for higher conduction bands. When A_peak is below π/a0 , the harmonic yield of the doped systems is stronger than the undoped systems. The atomic doping density also influences the field-strength dependent spectra.

The origin of long soft lags and the nature of the hard-intermediate state in black hole binaries

description: Fast variability of the X-ray corona in black hole binaries can produce a soft lag by reverberation, where the reprocessed thermalized disc photons lag behind the illuminating hard X-rays. This lag is small, and systematically decreases with increasing mass accretion rate towards the hard-soft transition, consistent with a decreasing truncation radius between the thin disc and X-ray hot inner flow. However, the soft lag suddenly increases dramatically just before the spectrum becomes disc-dominated (hard-intermediate state). Interpreting this as reverberation requires that the X-ray source distance from the disc increases dramatically, potentially consistent with switching to X-rays produced in the radio jet. However, this change in lag behaviour occurs without any clear change in hard X-ray spectrum, and before the plasmoid ejection event which might produce such a source (soft-intermediate state). Instead, we show how the soft lag can be interpreted in the context of propagation lags from mass accretion rate fluctuations. These normally produce hard lags, as the model has radial stratification, with fluctuations from larger radii modulating the harder spectra produced at smaller radii. However, all that is required to switch the sign is that the hottest Comptonized emission has seed photons which allow it to extend down in energy below the softer emission from the slower variable turbulent region from the inner edge of the disc. Our model connects the timing change to the spectral change, and gives a smooth transition of the X-ray source properties from the bright hard state to the disc-dominated states.

description: On August 17, 2017, Advanced LIGO and Virgo observed GW170817, the first gravitational-wave (GW) signal from a binary neutron star merger. It was followed by a short-duration gamma-ray burst, GRB 170817A, and by a non-thermal afterglow emission, opening the way for multi-messenger studies. In this work, a combined simultaneous fit of the electromagnetic (EM, specifically, the afterglow) and GW domains is implemented, both fitting the EM data with a GW-informed prior and fitting the EM and GW domains simultaneously. This fits are mathematically the same, but modelling the GW posterior instead of using the actual distribution in the former can lead to incorrect results. We treat the viewing angle as a common parameter shared across the two domains. In the EM afterglow modelling this parameter and the jet opening angle are correlated, leading to high uncertainties on their values. The joint EM+GW analysis eases this degeneracy, reducing the uncertainty compared to an EM-only fit. We also apply our methodology to a hypothetical GW170817-like event occurring in the next GW observing run at 136.5 Mpc, so that the afterglow flux is about one order of magnitude fainter, leaving only the peak of the light curve visible. The EM-only fit cannot constrain the viewing angle nor the jet opening angle, while folding the GW data into the analysis leads to tighter constraints only on the viewing angle. Moreover, it is impossible to identify the geometry of the jet, which can either be a top hat or a Gaussian structured jet.

description: The effect of toroidal rotation on both turbulent and neoclassical transport of tungsten (W) in tokamaks is investigated using the flux-driven, global, nonlinear 5D gyrokinetic code GYSELA. Nonlinear simulations are carried out with different levels of momentum injection that drive W to the supersonic regime, while the toroidal velocity of the main ions remains in the subsonic regime. The numerical simulations demonstrate that toroidal rotation induces centrifugal forces that cause W to accumulate in the outboard region, generating an in-out poloidal asymmetry. This asymmetry enhances neoclassical inward convection, which can lead to central accumulation of W in cases of strong plasma rotation. The core accumulation of W is mainly driven by inward neoclassical convection. However, as momentum injection continues, roto-diffusion, proportional to the radial gradient of the toroidal velocity, becomes significant and generate outward turbulent flux in the case of ion temperature gradient (ITG) turbulence. Overall, the numerical results from nonlinear GYSELA simulations are in qualitative agreement with the theoretical predictions for impurity transport, as well as experimental observations.

description: Dark matter simulations can serve as a basis for creating galaxy histories via the galaxy-dark matter connection. Here, one such model by Becker (2015) is implemented with several variations on three different dark matter simulations. Stellar mass and star formation rates are assigned to all simulation subhalos at all times, using subhalo mass gain to determine stellar mass gain. The observational properties of the resulting galaxy distributions are compared to each other and observations for a range of redshifts from 0-2. Although many of the galaxy distributions seem reasonable, there are noticeable differences as simulations, subhalo mass gain definitions, or subhalo mass definitions are altered, suggesting that the model should change as these properties are varied. Agreement with observations may improve by including redshift dependence in the added-by-hand random contribution to star formation rate. There appears to be an excess of faint quiescent galaxies as well (perhaps due in part to differing definitions of quiescence). The ensemble of galaxy formation histories for these models tend to have more scatter around their average histories (for a fixed final stellar mass) than the two more predictive and elaborate semi-analytic models of Guo et al (2013) and Henriques et al (2015), and require more basis fluctuations (using PCA) to capture 90 percent of the scatter around their average histories. The codes to plot model predictions (in some cases alongside observational data) are publicly available to test other mock catalogues at https://github.com/jdcphysics/validation . Information on how to use these codes is in the appendix.

description: This work presents the charge-coupled device (CCD) photometric survey of the old open cluster NGC 188. Time-series V-band photometric observations were conducted for ten nights in January 2017 using the Nanshan One-meter Wide-field Telescope (NOWT) to search for variable stars in the field of the cluster field. A total of 25 variable stars, including one new variable star, were detected in the target field. Among the detected variables, 16 are cluster member stars, and the others are identified as field stars. The periods, radial velocities, effective temperatures, and classifications of the detected variables are discussed in this work. Most of the stars' effective temperatures are between 4200 K and 6600 K, indicating their spectral types are G or K. The newly discovered variable is probably a W UMa system. In this study, a known cluster variable star (V21 = V0769 Cep) is classified as an EA-type variable star based on the presence of an 0.5 magnitude eclipse in its light curve.

Dividindo o mesmo espaço ocupado há anos pelos emojis, emoticons e smiles, os stickers correspondem às novas evoluções na construção dos diálogos que fazem uso das representações dos corpos e das expressões humanas. Sendo assim, os corpos, enquanto imagens, dizem tanto quanto as palavras, revelando informações codificáveis de formas objetivas e subjetivas através de diferentes modos semióticos encontrados na multimodalidade. Neste caminho seguimos com o aporte bibliográfico dos estudos da semiótica social de Kress e Van Leeuwen (1996; 1998; 2001) para realização da análise verbo-visual dos corpos-stickers em diálogos dentro da aplicação do WhatsApp.

Creators: name: Gebreyohannes, Nigisty
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The demand of world energy increases from time to time, this leads to gradual depletion of petroleum reserves, petroleum price rising and increases environmental problems. Beside to the above problems Ethiopia has additional diesel transportation cost. These all problems has motivated the search for sustainable and environment-friendly alternative renewable biofuels such as biodiesel. Since, it is non-toxic and capable of fulfilling an increasing energy demand. In this study biodiesel was produced by transesterification reaction in the presence of CaO with 99.5% ethanol. The biodiesel production process includes CSO extraction and CaO catalyst preparation from chicken egg shell waste. Moreover, this study characterizes the Physico-chemical properties of CSO and ethyl ester according ASTM D6751 standards to use the FAEE as an alternative fuel for diesel engines. All of the measured Physico-chemical properties of the biodiesel was in the range of the international standards. Design expert 7.0.0 with Box-Behnken was applied to investigate the effect of reaction parameters such as, reaction temperature (70, 75 and 80oC), ethanol to oil molar ratio (6:1, 9:1 and 12:1) and catalyst loading (1, 2 and 3%) on the yield of biodiesel. Significance of the process variables were analyzed by ANOVA. RSM was applied to investigate the interaction effect of process variables on the yield of biodiesel and to find the optimum yield. As the result of RSM optimization, the optimum yield of biodiesel 97.65 % w/w were found at an optimum reaction temperature of 73.71 oC, ethanol to oil ratio of 10.12:1 and a catalyst loading of 1.84 wt% of oil.

description: O objetivo deste trabalho foi analisar na concepção dos alunos, a importância da aula prática de “Extração de DNA de Allium cepa”, para a apreensão de conceitos de genética. A aula foi desenvolvida no auditório da Unidade Escolar Prof. José Amável, por alunos do 3º ano do ensino médio, com o auxílio de bolsistas do Programa de Bolsas Iniciação à Docência –Pibid. Após apresentação do seminário, realizou-se a extração e posteriormente aplicou-se um questionário pós-teste. Verificou-se que quase 100% dos alunos gostaram de realizar a aula prática, acham essa metodologia importante e acreditam que deve ter mais aulas práticas de biologia. Percebeu-se que os alunos imaginavam que ia ver a molécula de DNA tal qual imagens de livros didáticos e que houve apreensão de diversos conceitos de genética. Desse modo, a prática de extração de DNA de cebola estimulou o aprendizado aos alunos de forma dinâmica.

description: Life insurance is an important aspect of the social-economic development of the country. Despite its importance the attitude towards purchase of life insurance in Ethiopia is very low compared to other countries .The main intension of this research is to identify and inspect factors related to the demographic aspect and awareness in Ethio Life and General insurance share company Addis Ababa. Based on the literatures reviewed "age", "gender", "religion", "education" and "income " and "awareness " were identified. The study employed explanatory research design. The population of the study comprises of individual customers of Ethio Life and General insurance Share Company. Out of one hundred fifty five questionnaires administered, one hundred forty eight usable questionnaires were obtained constituting 94.2percent for analysis. Both primary and secondary data were used. The study employed structured questionnaires as the main research instrument. Descriptive statistics was used to summarize the respondents' demographic characteristics. T test and one way ANOVA test was applied to test the mean difference of the respondents on the demographic variables and lenear regression analysis was used to analyze the relationship between income and awareness with consumers' attitude towards purchase of life insurance. The outcome of the research demonstrates that from the identified factors income and awareness had significant relationship with the consumers' attitude towards the purchase of the life insurance policy. With these findings, this study provides a recommendation to make high awareness creation to the society by taking in to consideration the variables age , religion , gender and education about what life insurance is , what are the benefit package under each type of the products and if these are considered by the company under study and the insurance industry as a whole the consumers attitude towards purchase of life insurance will be positively improved and insurance consumption in turn will be greater than before.

description: Nonlinear optical responses are becoming increasingly relevant for characterizing the symmetries and quantum geometry of electronic phases in materials. Here, we develop an expanded diagrammatic scheme for calculating spatially dispersive corrections to nonlinear optical conductivities, which we expect to enhance or even dominate even-order responses in materials of recent interest. Building upon previous work that enforces gauge invariance of spatially uniform nonlinear optical responses, we review the cancellation of diagrams required to ensure the equivalence between velocity gauge and length gauge formulations, and provide a simple vertex rule for extending optical responses to first order in the light wave vector q. We then demonstrate the method with calculations on a prototypical centrosymmetric model where spatial dispersion admits anomalous secondharmonic generation, a response that is symmetry-forbidden under the dipole approximation.

description: This paper develops a systematic review of the international bibliography on mobile esports until September 2021. Its intent is to document the evolution, gaps and the first years of appropriation of this object by the academic community. The approach is guided by complementary mixed methodological procedures, aimed at the organization of knowledge and quali-quantitative in nature. The classification made for this study sought to gather the findings into blocks of analysis, firstly of bibliographic data, and then to build an epistemological/critical appreciation. Among the main results, the small volume of work on the mobile esports segment to date stands out. In the selected material, a low reflection on the subject predominates. Computing is the discipline that stands out, followed by Communication and Sports Sciences. (Este artigo desenvolve uma revisão sistemática da bibliografia internacional sobre esports móveis até setembro de 2021. Seu intuito é documentar a evolução, lacunas e os primeiros anos de apropriação deste objeto pela comunidade acadêmica. A abordagem é guiada por procedimentos metodológicos mistos complementares, voltados para a organização do conhecimento e de natureza quali-quantitativa. A classificação confeccionada para este estudo buscou reunir os achados em blocos de análises, primeiramente de dados bibliográficos para, em seguida, construir uma apreciação epistemológica/crítica. Entre os principais resultados, destaca-se o pequeno volume de trabalhos sobre o segmento de esports móveis até o momento. No material selecionado, predomina uma baixa reflexão sobre o assunto. Computação é a disciplina que se destaca, acompanhada da Comunicação e das Ciências do Esporte.)

description: The City of Austin collects and compiles data on Austin Police Department (APD) traffic stops annually. In early 2021, they released the data for 2020 APD traffic stops. This report adapts contemporary research methods to analyze this dataset with an aim of discerning whether and to what degree racial bias occurred throughout the city. Largely a spatial analysis, key findings point to East Austin’s historic areas of racial segregation—now areas of recent gentrification—as primary districts for disparate police traffic stop outcomes, though Black and Hispanic/Latino drivers were also found to be overrepresented in stops and searches across most of the city. This report concludes with a set of nine recommendations, first among them for Austin voters: vote “yes” for Proposition A and “no” for Proposition B on Austin’s May 6, 2023, ballot.

description: In recent years, automatic classifiers of image cutouts (also called "stamps") have shown to be key for fast supernova discovery. The Vera C. Rubin Observatory will distribute about ten million alerts with their respective stamps each night, enabling the discovery of approximately one million supernovae each year. A growing source of confusion for these classifiers is the presence of satellite glints, sequences of point-like sources produced by rotating satellites or debris. The currently planned Rubin stamps will have a size smaller than the typical separation between these point sources. Thus, a larger field of view stamp could enable the automatic identification of these sources. However, the distribution of larger stamps would be limited by network bandwidth restrictions. We evaluate the impact of using image stamps of different angular sizes and resolutions for the fast classification of events (AGNs, asteroids, bogus, satellites, SNe, and variable stars), using data from the Zwicky Transient Facility. We compare four scenarios: three with the same number of pixels (small field of view with high resolution, large field of view with low resolution, and a multi-scale proposal) and a scenario with the full stamp that has a larger field of view and higher resolution. Compared to small field of view stamps, our multi-scale strategy reduces misclassifications of satellites as asteroids or supernovae, performing on par with high-resolution stamps that are 15 times heavier. We encourage Rubin and its Science Collaborations to consider the benefits of implementing multi-scale stamps as a possible update to the alert specification.
