description: Recent studies have shown the potential for bipolar thermoelectricity in superconducting tunnel junctions with asymmetric energy gaps. The thermoelectric performance of these systems is significantly impacted by the inverse proximity effects present in the normal-superconducting bilayer, which is utilized to adjust the gap asymmetry in the junction. Here, we identify the most effective bilayer configurations, and we find that directly tunnel-coupling the normal metal side of the cold bilayer with the hot superconductor is more advantageous compared to the scheme used in experiments. By utilizing quasiclassical equations, we examined the nonlinear thermoelectric junction performance as a function of the normal metal film thickness and the quality of the normal-superconducting interface within the bilayer, thereby determining the optimal design to observe and maximize this nonequilibrium effect. Our results offer a roadmap to achieve improved thermoelectric performance in superconducting tunnel junctions, with promising implications for a number of applications.

description: The ground state of Bose-Einstein condensates with attractive particle interaction is metastable. One of the decay mechanisms of the condensate is a collapse by macroscopic quantum tunneling, which can be described by the bounce trajectory as solution of the time-dependent Gross-Pitaevskii equation in imaginary time. For condensates with an electromagnetically induced gravity-like interaction the bounce trajectory is computed with an extended variational approach using coupled Gaussian functions and simulated numerically exact within the mean-field approach on a space-time lattice. It is shown that the variational computations converge very rapidly to the numerically exact result with increasing number of Gaussians. The tunneling rate of the condensate is obtained from the classical action and additional parameters of the bounce trajectory. The converged variational and numerically exact results drastically improve by several orders of magnitude the decay rates obtained previously with a simple variational approach using a single Gaussian-type orbital for the condensate wave function.

The relationship between media exposure, personal experience and education on the public's perceptions of people with disabilities: A correlational study
Creators: name: Reichley, Melissa Lynn
Publisher: name: University of Nevada, Las Vegas

description: The Relationship Between Media Exposure, Personal Experience and Education on the Public's Perceptions of Disabilities seeks to determine whether there is any correlation between people's opinions about people with disabilities (PWDs), and their media consumption, education, and experience or contact with PWDs. The author compares such perceptions between respondents with and without disabilities. While research suggests nondisabled people view people with disabilities to varying degrees of negativity depending on the level and type of disability and accompanying social stigma attached, this researcher questions whether frequency of media exposure is having a positive influence on media consumers' perceptions of PWDs (which has been historically negative), as well as whether the type of media exposure has any influence.
A Quiz-Based Online Fundraising Proposal for UNICEF Madagascar: Strategies Based on An Online Experiment

Publisher: name: University of Chicago
Year: 2022
Subjects: subject: Online Fundraising + Fundraising + Nonprofit Management + Donation Behavior

description: Using an experimental approach, this project suggests innovation in building partnerships with individual donors for the United Nations International Children's Emergency Fund (UNICEF) Madagascar. A survey experiment is conducted to investigate how taking a quiz and giving different formats of feedback formats in a fundraising campaign impact people’s motivation to donate. The results suggest that when designing quiz-based fundraising campaigns, organizations should apply questions that emphasize the tragedy of a specific victim and provide ranking feedback to participants. The organizations can also customize different feedback responses targeting people with different performances in the quiz. To people with performance above average, rankings can be given to them as a motivation for more donations. To people with performance below average, other formats of greeting messages can be given to prevent them from avoiding donations. Based on the experiment results, I build my fundraising proposal for UNICEF Madagascar, aiming to help the organization reach out to more potential donors on social media and ultimately attract more individual donations.

description: In this study, we continue our previous work (Annu et al., 2023) by introducing a novel parametrization of the expansion scalar $Θ$ as a rational function of cosmic time $t$. The paper provides a comprehensive analysis of a homogeneous gravitational collapsing system, wherein the exact solutions of the Einstein field equations (EFEs) are determined using a new parametrization of $Θ$ in a model-independent way. The model is especially significant for the astrophysical applications because we have addressed the physical and geometrical quantities of the model in terms of Schwarzschild mass $M$. We have estimated the numerical value of the model parameter involved in the functional form of $Θ$-parametrization using the masses \& radii data of some massive stars namely, Westerhout 49-2, BAT99-98, R136a1, R136a2, WR 24, Pismis 24-1, $λ$ Cephei, $α$ Camelopardalis, $β$ Canis Majoris. We have presented theoretical investigations about such astrophysical stellar systems. The formation of apparent horizon is also studied for the collapsing system, and it has been shown that our model produces a continuing collapsing scenario of star (an eternal collapsing object).

description: It is pointed out that the "counter example" presented in the Comment is a family of probe wave functions which are increasingly broad as the shift becomes large. Furthermore, the author's variational calculation is not correct in the sense that we have to gauge fix the freedom of the phase translation. It is shown that there are two kinds of solutions, normalizable and un-normalizable. The former is our optimal solution, and the latter is what he found. It seems only the former is relevant from a practical point of view.

description: In this paper we develop a picture of Quantum Mechanics based on the description of physical observables in terms of expectation value functions, generalizing thus the so called Ehrenfest theorems for quantum dynamics. Our basic technical ingredient is the set of tools which has been developed in the last years for the geometrical formulation of Quantum Mechanics. In the new picture, we analyze the problem of the dynamical equations, the uncertainty relations and interference and illustrate the construction with the simple case of a two-level system.

description: Ever since deoxyribonucleic acid (DNA) was considered as a next-generation data-storage medium, lots of research efforts have been made to correct errors occurred during the synthesis, storage, and sequencing processes using error correcting codes (ECCs). Previous works on recovering the data from the sequenced DNA pool with errors have utilized hard decoding algorithms based on a majority decision rule. To improve the correction capability of ECCs and robustness of the DNA storage system, we propose a new iterative soft decoding algorithm, where soft information is obtained from FASTQ files and channel statistics. In particular, we propose a new formula for log-likelihood ratio (LLR) calculation using quality scores (Q-scores) and a redecoding method which may be suitable for the error correction and detection in the DNA sequencing area. Based on the widely adopted encoding scheme of the fountain code structure proposed by Erlich et al., we use three different sets of sequenced data to show consistency for the performance evaluation. The proposed soft decoding algorithm gives 2.3% ~ 7.0% improvement of the reading number reduction compared to the state-of-the-art decoding method and it is shown that it can deal with erroneous sequenced oligo reads with insertion and deletion errors.
What do today's business travelers want in terms of business service amenities
Creators: name: Seo, Won S
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: In the United States the numbers of business travelers has been growing at an increasing rate, becoming an important source of income in the hospitality industry. In 1995, according to the around 1.6 million businesses travelers traveled more than 50,000 miles and this number increased by seven percent from 1994; Business travelers are the major market segment of the hotel industry since most business travelers stay in hotels or motels during their business trips. In 1995, sixty-six percent of business travelers stayed in hotel or motels and that percentage is almost double of the leisure travelers' percentage (39%); As the number of business travelers continues to increase, the hotel industry needs to be ready to provide services for their major market segment. This requires that the industry should understand business travelers needs and wants; The purpose of this study was to identify the business service amenities that business travelers need at a hotel when they travel for business. Four objectives were established. The first objective was to identify those factors that influence business travelers to choose one hotel over another when they travel for business. The second objective was to identify one, if business travelers want hotels to have business centers; and two, the business service amenities they want in the business centers. The third objective was to identify the business service amenities that business travelers want in their hotel rooms. The fourth objective was to identify the pricing of business service amenities.

description: What is the highest energy at which gravitons can be observed? We address this question by studying graviton-to-photon conversion - the inverse-Gertsenshtein effect - in the magnetic field of the Milky Way. We find that above $\sim 1~\mbox{PeV}$ the effective photon mass grows large enough to quench the conversion rate. For sub-PeV energies, the induced photon flux is comparable to the sensitivity of LHAASO to a diffuse $γ$-ray background, but only for graviton abundances of order $Ω_{\text{gw}} h^2_0 \sim 1$. In the future, owing to a better understanding of $γ$-ray backgrounds, larger effective areas and longer observation times, sub-PeV shimmering gravitons with a realistic abundance of $Ω_{\text{gw}} h^2_0 \sim 0.01$ could be detected. We show how such a large abundance is achieved in a cosmologically-motivated scenario of post-recombination superheavy dark matter decay. Therefore, the sub-PeV range might be the ultimate energy frontier at which gravitons can be observed.

A self-consistent numerical model for multiple quantum well photovoltaic devices
Creators: name: Ramey, Stephen McHarry
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: In this work, a comprehensive numerical model is presented for a multi-quantum well pin photovoltaic device. The model accounts for the fundamental carrier dynamics in the quantum wells without assuming thermal equilibrium between the confined carriers and crystal lattice. It is based on a self-consistent solution of the Poisson, Schrodinger, and current continuity equations. In the quantum well regions, a second set of continuity equations is coupled to these three equations to account for the recombination, generation, escape, and capture in the quantum well. The effect of these quantum well rates on device performance is examined for various well configurations and material parameters. The simulation predicts that efficiency improvements above a baseline Al{dollar}\sb{\rm x}{dollar}Ga{dollar}\sb{\rm 1-x}{dollar}As control cell are possible for low mole fractions of aluminum. Furthermore, with proper design, a multiple quantum well device can exceed the efficiency of a similar quality, bulk GaAs pin device.

description: We carry out the calculation of kinematical higher-twist corrections to the cross section of $γ^* \to M_1 M_2 γ$ up to twist 4, where $M_i$ is a scalar or pseudoscalar neutral meson. The three independant helicity amplitudes are presented in terms of the twist-2 generalized distribution amplitudes (GDAs), which are important non-perturbative quantities for understanding the 3D structure of hadrons. Since this process can be measured by BESIII in $e^+ e^-$ collisions, we perform the numerical estimate of the kinematical higher-twist corrections by using the kinematics of BESIII. We adopt the $ππ$ GDA extracted from Belle measurements and the asymptotic $ππ$ GDA to study the size of the kinematical corrections in the case of pion meson pair, and a model $ηη$ GDA is used to see the impact of target mass corrections $\mathcal O(m^2/s)$ for $γ^* \to ηηγ$. Our results show that the kinematical higher-twist corrections account for $\sim 20\%$ of the cross sections at BESIII on the average, and it is necessary to include them if one tries to extract GDAs from experimental measurements precisely. We also comment the case of $π^0 η$ production which is important for the search of hybrid mesons.

description: Since its conception, the cryptocurrency market has been frequently described as an immature market, characterized by significant swings in volatility and occasionally described as lacking rhyme or reason. There has been great speculation as to what role it plays in a diversified portfolio. For instance, is cryptocurrency exposure an inflationary hedge or a speculative investment that follows broad market sentiment with amplified beta? We have recently explored similar questions with a clear focus on the equity market. There, our research revealed several noteworthy dynamics such as: an increase in the market's collective strength and uniformity during crises, greater diversification benefits across equity sectors (rather than within them), and the existence of a "best value" portfolio of equities. In essence, we can now contrast any potential signatures of maturity we identify in the cryptocurrency market and contrast these with the substantially larger, older and better established equity market. This paper aims to investigate whether the cryptocurrency market has recently exhibited similar mathematical properties as the equity market. Instead of relying on traditional portfolio theory, which is grounded in the financial dynamics of equity securities, we adjust our experimental focus to capture the presumed behavioral purchasing patterns of retail cryptocurrency investors. Our focus is on collective dynamics and portfolio diversification in the cryptocurrency market, and examining whether previously established results in the equity market hold in the cryptocurrency market, and to what extent. Results reveal nuanced signatures of maturity related to the equity market, including the fact that correlations collectively spike around exchange collapses, and identify an ideal portfolio size and spread across different groups of cryptocurrencies.

description: The rapid and insidious proliferation of online misinformation represents a significant societal problem. While a wealth of research has been dedicated to the topic, it is still unclear whether fake news is indeed more likely to be shared than accurate news and what the specific determinants of this behavior are. Our paper comparatively examines fake and accurate news sharing in a novel experimental setting manipulating news about terrorism. We follow an extended version of the uses-and-gratification framework for news sharing, complemented by the variables most commonly employed in fake news rebuttal studies. Logistic regression and classification trees revealed worry about the topic, media literacy, information-seeking, and conservatism as significant factors in predicting news sharing. In contrast, no significant association was found for general analytical thinking, journalism skepticism, conspiracy ideation, uses-and-gratification motives, or pass-time coping strategies. The current results broaden and expand the literature examining belief in and sharing of misinformation, highlighting the role of media literacy in protecting the public against the spread of fake news.

description: With the increased attention to memristive-based in-memory analog computing (IMAC) architectures as an alternative for energy-hungry computer systems for machine learning applications, a tool that enables exploring their device- and circuit-level design space can significantly boost the research and development in this area. Thus, in this paper, we develop IMAC-Sim, a circuit-level simulator for the design space exploration of IMAC architectures. IMAC-Sim is a Python-based simulation framework, which creates the SPICE netlist of the IMAC circuit based on various device- and circuit-level hyperparameters selected by the user, and automatically evaluates the accuracy, power consumption, and latency of the developed circuit using a user-specified dataset. Moreover, IMAC-Sim simulates the interconnect parasitic resistance and capacitance in the IMAC architectures and is also equipped with horizontal and vertical partitioning techniques to surmount these reliability challenges. IMAC-Sim is a flexible tool that supports a broad range of device- and circuit-level hyperparameters. In this paper, we perform controlled experiments to exhibit some of the important capabilities of the IMAC-Sim, while the entirety of its features is available for researchers via an open-source tool.

description: Pushing the limits of precision and reproducibility in ultrafast laser-based nanostructuring requires detailed control over the properties of the illumination. Most traditional methods of laser-based manufacturing rely on the simplicity of Gaussian beams for their well-understood propagation behavior and ease of generation. However, a variety of benefits can be obtained by moving beyond Gaussian beams to single or multiple tailored beams working toward optimal spatial and temporal control over the beam profiles. In this chapter, we center our attention on methods to generate and manipulate complex light beams and the resulting material interactions that occur in response to irradiations with these non-traditional sources. We begin with a discussion on the main differences between Gaussian and more complex light profiles, describing the mechanisms of phase and spatial control before narrowing the discussion to approaches for spatial structuring associated with materials processing with ultrashort laser pulses. Such structuring can occur in both far-field propagating architectures, considering rapidly varying spatial profiles generated mechanically or optically, as well as near-field, non-propagating beams associated with plasmonic and dielectric systems. This chapter emphasizes some of the unique abilities of complex light to shape materials at the nanoscale from a fundamental perspective while referencing potential applications of such methods.

description: We present a phenomenological study of charm quark photoproduction in longitudinally polarized lepton-hadron collisions at next-to-leading order accuracy of QCD. Our results are based on a recently developed, flexible parton-level Monte Carlo program for spin-dependent heavy flavor hadroproduction, which we extend to deal also with both direct and resolved photon contributions. The subsequent hadronization into charmed mesons is modeled in our calculations, which allows us to compare with data on double-spin asymmetries for D0 meson production taken by the COMPASS collaboration. In general, next-to-leading order QCD corrections are found to be very significant and do not cancel in spin asymmetries. We elucidate the role of the individual hard scattering subprocesses and determine the range of parton momentum fractions predominantly probed for charm production at COMPASS. Theoretical uncertainties are estimated by varying renormalization and factorization scales and parameters controlling the hadronization of the charm quarks.

description: Data Management Plans (DMPs) are crucial for a structured research data management and often a mandatory part of research proposals. The manual creation of DMPs can be very time-consuming, since many researchers have to start from scratch, are unsure about the required content and may run the risk of not meeting the funder requirements. By using tools, DMPs can be effectively developed and managed. There are a variety of tools to support the development of DMPs: from disciplineagnostic DMP tools, which can be used to generate a generic draft DMP, to discipline-specific DMP tools, which support the creation of a DMP in a specific research field, such as psychology, biodiversity, engineering, or the life sciences. Our aim is to develop a quick and easy to use DMP service for members of Saxon research institutions, building on existing work. In order to evaluate the existing tools and identify which one to choose as the basis for the Saxon tool, we defined 31 requirement parameters covering aspects with regard to basic functions, technical aspects and userfriendliness. Additionally, a weight factor between zero (not relevant) and three (high priority) was assigned to every parameter. Based on these parameters, we evaluated 18 mainly open access DMP tools to find the ones that meet our needs best. Experience from RDM consultancy showed that researchers find pre-fabricated text passages very helpful, which are automatically generated by the DMP tool based on their input. Accordingly, the corresponding requirement parameters are of high importance to us. The only tools generating pre-fabricated text passages while also providing the tool's source code were Data Stewardship Wizard, DataPLAN from NFDI4plants and the DMP tool provided by the TU Dresden Service Center Research Data. The highest total evaluation scores out of a maximum of 790 were reached by Data Stewardship Wizard (733.5), DMPTool (645.5) and RDMO NFDI4Ing (579.5). In a next step, we will check the feasibility of adapting each of the three tools according to our needs and estimate the respective workload. The most suitable DMP tool will then be customized for our requirements.
Feasibility of integrating photovoltaic cells in low-rise office building design

Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: This research is an investigation of integrating photovoltaic solar collecting cells into a low-rise office building design providing a sustainable power source meeting or exceeding peak energy demands. The data focuses on roof-mounted installations examining the costs of collecting and transferring solar energy into the existing power grid using U.S. government statistics and projected costs. In addition, the possibility of exporting surplus power for revenue as an alternative energy supplier was explored. Studies of similar research were documented to demonstrate feasibility of alternative PV installations. The purpose of the study examines whether a self-reliant building can be economically feasible using solar energy for electric power. The data suggests photovoltaic energy does not pay for itself during its life cycle at the current electricity rate, but economic feasibility can be expected in the next decade assuming average inflation rate projections.

description: The recently emerging superconductivity in infinite-layer nickelates, with isostructure and isoelectron of cuprates, provides a new platform to explore the pairing mechanism of high-temperature superconductors. In this work, we studied the upper critical field ($H_{\rm{c2}}$) of a high-quality La$_{0.8}$Sr$_{0.2}$NiO$_{2}$ thin film with superconducting transition temperature, $T_{\rm{c}}$ = 18.8 K, using high magnetic field up to 56 T. A very large $H_{\rm{c2}}$, $\sim$ 40 T for $H$ $\Arrowvert$ $c$ and $\sim$ 52 T for $H$ $\Arrowvert$ $ab$, was confirmed, which suggests that infinite-layer nickelates also have great application potential. The anisotropy of $H_{\rm{c2}}$ monotonically decreases from $\sim$ 10 near $T_{\rm{c}}$ to $\sim$ 1.5 at 2 K. Angle dependence of $H_{\rm{c2}}$ confirms the crossover of superconductivity from two-dimensional (2D) to three-dimensional (3D) as the temperature decreases. We discussed that the interstitial orbital effect causes the weakening of anisotropy. The observed abnormal upturning of $H_{\rm{c2}}$ at low temperatures is found to be a universal behavior independent of film quality and rare earth elements. Therefore, it should not be the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state due to the fact that it is in the dirty limit and insensitive to disorder.

description: A method for estimating return values from ensembles of forecasts at advanced lead times is presented. Return values of significant wave height in the North-East Atlantic, the Norwegian Sea and the North Sea are computed from archived +240-h forecasts of the ECMWF ensemble prediction system (EPS) from 1999 to 2009. We make three assumptions: First, each forecast is representative of a six-hour interval and collectively the data set is then comparable to a time period of 226 years. Second, the model climate matches the observed distribution, which we confirm by comparing with buoy data. Third, the ensemble members are sufficiently uncorrelated to be considered independent realizations of the model climate. We find anomaly correlations of 0.20, but peak events (>P97) are entirely uncorrelated. By comparing return values from individual members with return values of subsamples of the data set we also find that the estimates follow the same distribution and appear unaffected by correlations in the ensemble. The annual mean and variance over the 11-year archived period exhibit no significant departures from stationarity compared with a recent reforecast, i.e., there is no spurious trend due to model upgrades. EPS yields significantly higher return values than ERA-40 and ERA-Interim and is in good agreement with the high-resolution hindcast NORA10, except in the lee of unresolved islands where EPS overestimates and in enclosed seas where it is biased low. Confidence intervals are half the width of those found for ERA-Interim due to the magnitude of the data set.

Low harmonic distortion flash A/D converters incorporating dynamic element matching techniques
Creators: name: Steadman, Bret David
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: New dynamic element matching techniques are shown to reduce the harmonic distortion and improve the spurious-free dynamic range of flash ADCs. Resistor chain mismatch errors are negated by randomly rearranging the resistors each sample by utilizing 5(2{dollar}\sp{b}{dollar}-1) digital switches and b + 1 random control signals for a b-bit flash ADC. The integral and differential nonlinearity of a non-ideal flash ADC are derived for three common resistor chain mismatch errors; namely, geometric mismatches, linear gradient mismatches, and dynamic mismatches. The transfer function of a non-ideal flash ADC is also derived and the converter output is shown to consist of a scaled copy of the input, a DC gain, and conversion noise that is a function of the resistor mismatches. A comprehensive summary of dynamic element matching techniques given in literature is provided. In addition, the DEM network introduced by Galton and Jensen is shown to be equivalent to the generalized-cube network used in parallel processing architectures. An alternative version of this network that uses logic gates is also proposed.

description: Surface nanostructures provide the possibility to create and tailor surface functionalities mainly via controlling their topography along with other chemical and physical material properties. One of the most appealing technologies for surface functionalization via micro- and nanostructuring is based on laser processing. This can be done either via direct contour-shaping of the irradiated material using a tightly focused laser beam or in a self-ordered way that allows employing larger laser beam diameters along with areal scanning to create a variety of laser-induced periodic surface structures (LIPSS). For the latter approach, particularly ultrashort pulsed lasers have recently pushed the borders across long-lasting limitations regarding the minimum achievable feature sizes and additionally boosted up the production times. This chapter reviews the plethora of recently investigated applications of LIPSS-for example, via imposing diffractive or plasmonic structural colors, the management of liquids and surface wetting properties, biomedical and bioinspired functionalities, beneficial effects in tribology for reducing friction and wear, the manipulation of optical scattering and absorption in photovoltaics, or the modification of magnetic or superconducting surface properties in other energy applications. The footprint of the LIPSS-based technology is explored in detail regarding the current state of industrialization, including an analysis of the market and associated LIPSS production costs.

description: Previous research has shown the effects of physical spacing within mathematics notation on students’ performance on arithmetic problems. Specifically, students’ performance improves when viewing problems with spacing that is congruent to the order of operations (e.g., 7*7 - 4) and decreases when viewing problems with incongruent spacing (e.g., 7 * 7+4; e.g., Braithwaite et al., 2016; Harrison et al., 2020; Landy & Goldstone, 2007). However, in a recent study, we analyzed data from an online experiment at the student level and found no effect of spacing on college students’ overall accuracy and average response time when solving order-of-operations problems. To follow up, we will analyze the data at the problem level to explore how the problem features (i.e., higher-order operator position) and study design choices (i.e., interleaving problem types) may have had nuanced effects on students’ performance. These findings should inform cognitive theory and future research study design decisions in this area.
Alfven Wave Collisions, The Fundamental Building Block of Plasma Turbulence I: Asymptotic Solution

description: The nonlinear interaction between counterpropagating Alfven waves is the physical mechanism underlying the cascade of energy to small scales in astrophysical plasma turbulence. Beginning with the equations for incompressible MHD, an asymptotic analytical solution for the nonlinear evolution of these Alfven wave collisions is derived in the weakly nonlinear limit. The resulting qualitative picture of nonlinear energy transfer due to this mechanism involves two steps: first, the primary counterpropagating Alfven waves interact to generate an inherently nonlinear, purely magnetic secondary fluctuation with no parallel variation; second, the two primary waves each interact with this secondary fluctuation to transfer energy secularly to two tertiary Alfven waves. These tertiary modes are linear Alfven waves with the same parallel wavenumber as the primary waves, indicating the lack of a parallel cascade. The amplitude of these tertiary modes increases linearly with time due to the coherent nature of the resonant four-wave interaction responsible for the nonlinear energy transfer. The implications of this analytical solution for turbulence in astrophysical plasmas is discussed. The solution presented here provides valuable intuition about the nonlinear interactions underlying magnetized plasma turbulence, in support of an experimental program to verify in the laboratory the nature of this fundamental building block of astrophysical plasma turbulence.

description: ALMA has spatially resolved over 200 annular structures in protoplanetary discs, many of which are suggestive of the presence of planets. Constraining the mass of these putative planets is quite degenerate for it depends on the disc physical properties, and for simplicity a steady-state is often assumed whereby the planet position is kept fixed and there is a constant source of dust at the outer edge of the disc. Here we argue against this approach by demonstrating how the planet and dust dynamics can lift degeneracies of such steady-state models. We take main disc parameters from the well-known protoplanetary disc HD 163296 with a suspected planet at $R\approx 86$~au as an example. By running gas and dust hydrodynamical simulations post-processed with dust radiative transfer calculations, we first find steady-state disc and planet parameters that reproduce ALMA continuum observations fairly well. For the same disc mass, but now allowing the planet to migrate in the simulation, we find that the planet undergoes runaway migration and reaches the inner disc in $\sim 0.2$ Myr. Further, decreasing the disc mass slows down planet migration, but it then also increases the dust's radial drift, thereby depleting the disc dust faster. We find that the opposing constraints of planet migration and dust drift require the disc mass to be at most $0.025~M_{\odot}$, must less massive than previously estimated, and for the dust to be porous rather than compact. We propose that similar analysis should be extended to other sources with suspected planetary companions.
