The role of gender equality in advancing development
Authors: Xu Chengwei , Mussagulova Assel , Zhou Qinrou 
Published: March 2024

AbstractGender equality and women empowerment are central to academic and policy debates on development. In the spirit of celebrating and reflecting on 75 years of research published by Public Administration and Development (PAD), this article aims to take stock of the journal's contribution to the knowledge base and practice of promoting gender equality. This article reviews research output published in PAD and identifies key themes and perspectives on gender equality and their reflection on the practical implementation of equalising policies. We use thematic analysis to review 43 relevant articles and evaluate the intellectual landscape, shedding light on the journal's contribution to gender equality research. Four broad themes are discussed along with their implications for practice and future research. We highlight the importance of not only expanding the horizons of gender equality research but also developing keen awareness reflected in the scholarship of the changing landscape of gender and the need to balance constructions of gender and the high variability of gender norms and practices in the Global South that should be taken into account when designing policies. This article concludes with recommendations and several questions that invite public administration researchers and policymakers to take this conversation and develop it further through research, education, and practice.

AbstractThe calibration of JWL‐Miller equation of state (EOS) parameters for aluminized explosive is a cumbersome but important work in explosive evaluation. Manual calibration is usually adopted while the work may be tedious and the optimal results may be unachievable. An automatic calibrating method was established to optimize this procedure based on genetic algorithm program and finite element software. Optimal JWL‐Miller EOS parameters were achieved by iterative calculation calibrating with cylinder test results and underwater‐explosion experiment results. Cylinder test results were adopted to illustrate the initial phase of explosion, and underwater explosion experiments were conducted to calibrating the Miller term of the equation of state. The results showed that the error between cylinder test and simulation result was less than 1 %, the error of underwater explosion impulse between test and simulation results was less than 3.73 %. The optimized parameters of JWL‐Miller EOS will be useful in the numerical simulation research of aluminized explosives.
Theoretical study of the interfacial force‐field and thermodynamic properties for HMX‐Estane mixture explosives
Authors: Long Yao , Chen Jun 
Published: March 2024

AbstractA transferable force‐field of HMX/Estane interface is derived by first‐principles calculation and least square optimization. Based on the force‐field, the plastic bonded explosive consists of HMX and Estane is simulated by molecular dynamics. The polycrystal structure is obtained, and a set of thermodynamic properties are calculated, including the heat capacity, thermal expansion coefficients, bulk modulus, elastic constants and Hugoniot curve. We find that the mixture explosive has higher thermal expansion coefficient than single crystal, because the interface is debonding at high temperature condition.
Exploring Quantum Annealing Architectures: A Spin Glass Perspective
Authors: Jaumà Gabriel , García‐Ripoll Juan José , Pino Manuel 
Published: March 2024

AbstractThis work analyzes the spin‐glass transition across various Ising models relevant to quantum annealers. By employing the parallel tempering method, the location of the spin‐glass phase transition is extrapolated from the pseudo‐critical temperature of finite‐sized systems. The results confirm a spin‐glass phase at finite temperature in random‐regular and small‐world graphs, in agreement with previous studies. However, strong evidence is obtained that this phase only occurs at zero temperature in the quasi‐2D graphs of D‐Wave, as their pseudo‐critical temperature drifts toward zero. This implies that the asymptotic runtime to find the low‐energy configuration of those graphs is likely to be polynomial in the size of the problem. Nevertheless, this scaling may only be reached for system sizes much larger than existing annealers, as the drift in the pseudo‐critical temperature is slow. This slowness, together with an abrupt increase in thermalization times around the pseudo‐critical temperature, may render the search for low‐energy configurations with classical methods impractical.
Prescribed‐time global stabilization for MIMO nonlinear systems with a linear time‐varying control mechanism
Authors: Zhang Wenli , Liu Xiaoping , Jing Yuanwei 
Published: March 2024

AbstractIn this article, the prescribed‐time global stabilization problem is taken into consideration when it comes to multi‐input‐multi‐output (MIMO) systems with unknown mismatched coupling nonlinear items. It is assumed that the unknown nonlinearities satisfy the linear growth conditions. First, a class of MIMO coupling nonlinear systems with controllable canonical form are considered. Then, by wielding a time‐varying Lyapunov‐like function and properties of parametric Lyapunov equations, a high‐gain linear time‐varying state feedback control law is developed to attenuate the impact of unknown nonlinear terms. Meanwhile, all state signals and control inputs are globally bounded and the target system becomes stable within the prescribed‐time. Finally, the simulation results on an example system with 3 inputs and 11 state variables verify that the developed control mechanism accomplishes the goal of global stabilization in the pre‐defined time.

Published: March 2024

AbstractPyrazole compounds have garnered attention due to their potential biological and medicinal qualities. Therefore, the purpose of the research being described is to utilize 3,5‐dimethyl‐1H‐pyrazole‐1‐carbothiohydrazide (1) as a starting material in a one‐pot synthesis to create novel pyrazole derivatives with potential biological applications. When either ethanol or acetic acid was added, components 1 and 1,3‐diphenylpropane‐1,3‐dione (2) reacted to produce derivative 3. Compound 1, when combined with ethanol, chemical 2, or acetyl acetone 5 and triethylamine, yielded chemicals 4 and 6 respectively. When ingredient 1 was mixed with ethyl cyanoacetate (7), stearic acid (10), or carboxylic acids 12 a–c, 9, 11, and 13 a–c were formed as a result. The equivalent 1,3,4‐thiadiazine derivatives, 15 and 17, were produced when 1 was mixed with either 14 or 16. The developed compounds′ cytotoxic properties were evaluated against lung and liver cancer. Our research identified a number of interesting bioactive chemicals, among which chemical 17 exhibited the greatest effectiveness against lung and liver cancer as well as the highest selectivity index measurements. It indicated a strong IC50 value of 5.35 and 8.74 μM, accordingly, when compared with 3.78 and 6.39 μM for the reference medication cisplatin. Additionally, its safety for use has been confirmed.

Published: March 2024

AbstractSolar energy is a primary form of renewable energy, and photothermal conversion is a direct conversion process with tunable conversion efficiency. Among various kinds of photothermal conversion materials, porous organic polymers (POP) are widely investigated owing to their controllable molecular design, tailored porous structures, good absorption of solar light, and low thermal conductivity. A variety of POP, such as conjugated microporous polymers (CMP), covalent organic frameworks (COF), hyper‐crosslinked porous polymers (HCP), polymers of intrinsic microporosity (PIM), porous ionic polymers (PIP), are developed and applied in photothermal conversion applications of seawater desalination, latent energy storage, and biomedical fields. In this review, a comprehensive overview of the recent advances in POP for photothermal conversion is provided. The micro molecular structure characteristics and macro morphology of POP are designed for applications such as seawater desalination, latent heat energy storage, phototherapy and photodynamic therapy, and drug delivery. Besides, a probe into the underlying mechanism of structural design for constructing POP with excellent photothermal conversion performance is methodicalized. Finally, the remaining challenges and prospective opportunities for the future development of POP for solar energy‐driven photothermal conversion applications are elucidated.
First occurrence of family Clavatoraceae (fossil Charophyta) in the Middle Jurassic (Bathonian) of France
Authors: Trabelsi Khaled , Sames Benjamin , Martín‐Closas Carles 
Published: March 2024

AbstractA rich and diverse charophyte flora is described from the Bathonian marginal marine beds of southern France. It includes nine species that belong to the families Porocharaceae, Characeae and Clavatoraceae: Porochara gr. fusca, P. gr. kimmeridgensis subgr. kimmeridgensis, P. gr. kimmeridgensis subgr. westerbeckensis, P. gr. kimmeridgensis subgr. douzensis, P. gr. kimmeridgensis subgr. obovata, Auerbachichara saidakovskyi, A. tataouinensis, Aclistochara mädleri and Echinochara cf. peckii. This is the most diverse Middle Jurassic flora reported from France and Laurasia to date, elucidating a turnover in the evolution of charophytes during this time interval. The occurrence of the clavatoracean Echinochara cf. peckii in these Bathonian deposits represents the oldest record of the genus and of the whole family, c. 10 myr older than previous records. This species is considered to be the most basal species in the phylogeny of Clavatoraceae and during its evolutionary history reached a wide biogeographical range in Laurasia. The new Bathonian charophyte assemblage from southern France provides supplementary evidence that the Middle Jurassic was a reactivation pulse in the Mesozoic evolution of charophytes, rather than a stasis as previously thought. Moreover, it provides further support to the hypothesis that during the Late Jurassic and Early Cretaceous the islands of the Cretaceous Tethyan Archipelago represented one of the most active spots of charophyte diversity.

Published: March 2024

AbstractThe two models of microwave assisted aqueous two‐phase extraction (MATPE) of polysaccharides from Malus hupehensis are established by response surface methodology (RSM) and back propagation neural network (BP‐NN), compared their prediction ability, and comparatively optimized extraction process by using RSM and BP‐NN coupled genetic algorithm (GA), and the antioxidant activity of M. hupehensis polysaccharides (MHPs) is evaluated by the scavenging ability of free radicals. The results show that the predictive ability of BP‐NN is significantly better than that of RSM. The optimal extraction parameters to achieve the highest MHPs yield (4.71 ± 0.04)% by MATPE are obtained through BP‐NN coupled GA method under the microwave power of 337 W, mass fraction of ammonium sulfate of 23%, ethanol concentration of 29%, and liquid‐to‐solid ratio of 22 mL g−1. The IC50 values of 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and hydroxyl radicals (OH) scavenging capacities for MHPs achieve 5.13 and 3.29 mg mL−1, respectively. The findings provide important references for the development and utilization of M. hupehensis.
Prediction on wind‐induced responses for tall buildings considering frequency dependency of viscoelastic damped structures
Authors: Sato Daiki , Chang Ting‐Wei 
Published: March 2024

SummaryTime history analysis is sometimes used in an estimation of the wind‐induced response of a tall building. However, time history analysis for the wind‐induced behavior by the ensemble‐averaging wind force costs much computation time. This paper provides a reliable prediction method for the wind‐induced response of the viscoelastic (VE)‐damped system considering its frequency dependency coupling with frame damping effect with frequency spectral method. VE damper used in high‐rise buildings can dissipate energy from excessive vibration induced by seismic or wind excitation. Fractional derivative (FD) model of VE dampers can express VE frequency dependency clearly, but it is computationally complicated. The herein proposed prediction method is based on frequency spectral method and evaluated wind‐induced responses of the single degree of freedom (SDOF) VE‐damped system with a FD VE damper subjected to the respective 1st modal along‐ and across‐wind force. The maximum error of wind‐induced responses of the VE‐damped system, such as the root mean square value of responses, the total input energy, and the total energy dissipation, is within
. In summary, the proposed method had high accuracy in the prediction of wind‐induced responses of the VE‐damped system considering its frequency dependency with the coupling effect of frame damping.

TDiff in the dark: gravity with a scalar field invariant under transverse diffeomorphisms
Authors: Jaramillo-Garrido Darío , Maroto Antonio L. , Martín-Moruno Prado 
Published: March 2024

Abstract
We reflect on the possibility of having a matter action that is invariant only under transverse diffeomorphisms. This possibility is particularly interesting for the dark sector, where no restrictions arise based on the weak equivalence principle. In order to implement this idea we consider a scalar field which couples to gravity minimally but via arbitrary functions of the metric determinant. We show that the energy-momentum tensor of the scalar field takes the perfect fluid form when its velocity vector is time-like. We analyze the conservation of this tensor in detail, obtaining a seminal novel result for the energy density of this field in the kinetic dominated regime. Indeed, in this regime the fluid is always adiabatic and we obtain an explicit expression for the speed of sound. Furthermore, to get insight in the gravitational properties of these theories, we consider the fulfillment of the energy conditions, concluding that nontrivial physically reasonable matter violates the strong energy condition in the potential domination regime. On the other hand, we present some shift-symmetric models of particular interest. These are: constant equation of state models (which may provide us with a successful description of dark matter or dark radiation) and models presenting different gravitational domains (characterized by the focusing or possible defocusing of time-like geodesics), as it happens in unified dark matter-energy models.

A nonlocal Lagrangian traffic flow model and the zero-filter limit
Authors: Coclite G. M. , Karlsen K. H. , Risebro N. H. 
Published: March 2024

AbstractIn this study, we start from a Follow-the-Leaders model for traffic flow that is based on a weighted harmonic mean (in Lagrangian coordinates) of the downstream car density. This results in a nonlocal Lagrangian partial differential equation (PDE) model for traffic flow. We demonstrate the well-posedness of the Lagrangian model in the $$L^1$$

L

sense. Additionally, we rigorously show that our model coincides with the Lagrangian formulation of the local LWR model in the “zero-filter” (nonlocal-to-local) limit. We present numerical simulations of the new model. One significant advantage of the proposed model is that it allows for simple proofs of (i) estimates that do not depend on the “filter size” and (ii) the dissipation of an arbitrary convex entropy.
Numerical solution of fractional PDEs through wavelet approach

Published: March 2024

AbstractTo solve fractional partial differential equations (FPDEs) under various physical conditions, this study developed a novel method known as the Hermite wavelet method employing the functional integration matrix. The method that has been suggested is based on the Hermite wavelet collocation process. To determine the solution of the fractional differential equations, the Caputo fractional derivative operator of order $$\alpha \in (0,1]$$

is used. With the use of appropriate grid points, this method converts FPDEs into a system of nonlinear algebraic equations. We achieve a solution by solving these nonlinear algebraic equations by the Newton–Raphson method. Tables and graphs show that the suggested method produces superior results. We provide various illustrative examples to establish the effectiveness of the suggested concept, and the outcomes support the applicability of the suggested strategy. Obtained results are numerically expressed in terms of absolute errors. Finally, convergence analyses are discussed as some theorem with proof.
Temporal teacher with masked transformers for semi-supervised action proposal generation
Authors: Pehlivan Selen , Laaksonen Jorma 
Published: March 2024

AbstractBy conditioning on unit-level predictions, anchor-free models for action proposal generation have displayed impressive capabilities, such as having a lightweight architecture. However, task performance depends significantly on the quality of data used in training, and most effective models have relied on human-annotated data. Semi-supervised learning, i.e., jointly training deep neural networks with a labeled dataset as well as an unlabeled dataset, has made significant progress recently. Existing works have either primarily focused on classification tasks, which may require less annotation effort, or considered anchor-based detection models. Inspired by recent advances in semi-supervised methods on anchor-free object detectors, we propose a teacher-student framework for a two-stage action detection pipeline, named Temporal Teacher with Masked Transformers (TTMT), to generate high-quality action proposals based on an anchor-free transformer model. Leveraging consistency learning as one self-training technique, the model jointly trains an anchor-free student model and a gradually progressing teacher counterpart in a mutually beneficial manner. As the core model, we design a Transformer-based anchor-free model to improve effectiveness for temporal evaluation. We integrate bi-directional masks and devise encoder-only Masked Transformers for sequences. Jointly training on boundary locations and various local snippet-based features, our model predicts via the proposed scoring function for generating proposal candidates. Experiments on the THUMOS14 and ActivityNet-1.3 benchmarks demonstrate the effectiveness of our model for temporal proposal generation task.
Global liquidity spillovers in the Asia–Pacific region: policy-driven versus market-driven effects
Authors: Le Chau , Nguyen Huyen , Vo Duc 
Published: March 2024

AbstractThis research investigates the spillovers of global liquidity to Asia–Pacific countries, focusing on the contradictory effects of policy-driven liquidity created by monetary stances in advanced economies and market-driven liquidity generated by the private banking sector. Our findings stand in sharp contrast to previous studies, showing that shifts in macro-financial indicators in Asia–Pacific economies are predominantly influenced by market-driven shocks rather than those of policy-driven liquidity. Specifically, liquidity shocks associated with surges in cross-border credit flows, especially those denominated in US dollars, drive up asset prices and have boosting effects on inflation and economic output. A positive shock to market liquidity also results in an appreciation pressure on domestic currencies and a short-term rise in interest rates. However, excess liquidity shocks caused by the Bank of Japan’s adjustments in shadow short rates and balance sheets have a negative effect on inflation and bring about temporary depreciation pressure on Asian currencies. Surprisingly, we find that Asian responses to financial easing associated with the Fed’s monetary policy change are not well-pronounced.
Efficient equilibria in common interest voting games
Authors: Kawamura Kohei , Vlaseros Vasileios 
Published: March 2024

AbstractWe develop a unified derivation of asymmetric pure strategy equilibria and their optimality in the canonical common interest voting model of Austen-Smith and Banks (Am Polit Sci Rev 90(1):34–45, 1996). We also study the relationship between the most efficient equilibria, which have a remarkably simple and intuitive structure, and the symmetric mixed strategy equilibrium that has been commonly studied in the literature. In particular, while the efficiency in the symmetric mixed strategy equilibrium under unanimity rule is known to be decreasing in the number of voters, the efficiency does not depend on the number of voters above a threshold in the most efficient equilibria.
