... Surfaces of objects immersed in liquid develop an electric charge density that depends on the types and concentrations of dissolved ions. The strength and spatial distribution of this charge density controls a myriad of processes, from biological to industrial processes. In addition, the lack of a full understanding of the charge density precludes a complete foundational interpretation of liquid-m ...
... A novel densimeter based on a random temperature signal cross-correlation method was designed and constructed. Liquid densities of n-decane were measured at T = (293.2–493.5) K and p = (0.1–20.0) MPa. The expanded uncertainties in liquid density measurements are 1.16%, with a confidence level of 0.95 (k = 2). This experimental study provides new n-decane densities to examine Lemmon's equations' ac ...
... Stochastic models of replication timing posit that origin firing timing is regulated by origin firing probability, with early-firing origins having a high probability of firing and late-firing origins having a lower probability. However, they offer no insight into why one origin should have a higher firing probability than another. Here, a simple framework is suggested for how to approach the ques ...
... A system of slow convective thermals is considered in a vicinity of convection level. It is shown that a system of spherical convective thermals of fixed radius can be described by a stochastic equation, which is practically identical to Langevin equation for an ensemble of classical Brownian particles. Under the proposed approach, it was shown that the mean vertical velocity of a system of therma ...
... A mistake of applying pseudo-first-order (PFO) kinetic model in the three papers has been pointed out. Also a correct PFO kinetic equation is given. In addition, a suggestion is made for avoiding using erroneous PFO kinetic equations in adsorption systems. ...
... Following the trend of green product consumption, farmers’ markets sell green products and have gradually developed the promotion of environmentally friendly knowledge of food and agricultural education. However, past research on farmers’ markets has rarely been combined with the function of food and agricultural education. Therefore, this study explores the relationship between product knowledge, ...
... The aeromagnetic survey is a common remote sensing tool for detecting iron deposits. The local wavenumber of a magnetic anomaly is used to interpret the edges or positions of the sources, and can involve first- or second-order local wavenumbers. In this paper, we derived a linear equation between the second-order local wavenumber and the source location; therefore, we propose a constraint of first ...
... We describe a formulation to solve reactive transport (RT) problems. The basic idea is to represent transport as mixing water instead of individual solute concentrations, hence the Water Mixing Approach (WMA) name. This conceptual representation simplifies RT calculations as it decouples transport from chemistry. Transport is first solved in terms of water mixing ratios (λ), which we show is feasi ...
... Predicting countries’ energy consumption and pollution levels precisely from socioeconomic drivers will be essential to support sustainable policy-making in an effective manner. Current predictive models, like the widely used STIRPAT equation, are based on rigid mathematical expressions that assume constant elasticities. Using a Bayesian approach to symbolic regression, here we explore a vast amou ...
... In this paper, for the first time, the effect of the longitudinal profile shape of the rill (uniform, concave, and convex) on flow resistance law was studied. The first part of the paper is based on a theoretical equation to estimate the Darcy–Weisbach friction factor f, deduced from the power velocity distribution and rill measurements performed on a plot. At first, the equation to estimate the Γ ...

Abstract:
... The recent wave of foreign land acquisitions (FLA) has raised several concerns in terms of their environmental and social sustainability. An unexplored issue is whether pollution‐haven mechanisms are driving the pattern of FLA. This paper investigates whether and how differences in environmental stringency between investing and target country affect the pattern of FLA. We estimate a panel gravity ...

Abstract:
... Shajiang black soil (Vertisol) has a high shrinkage capacity and contains many calcareous concretions (CC). We assume the volume of CC to be rigid during wetting and drying cycles. Thus, the soil containing CC may have different shrinkage behavior from that of fine soils (without CC). We aimed to quantify the effects of CC content and size on soil shrinkage behavior, as well as to develop a model ...
... Like-charge attraction, driven by ionic correlations, challenges our understanding of electrostatics both in soft and hard matter. For two charged planar surfaces confining counterions and water, we prove that, even at relatively low correlation strength, the relevant physics is the ground-state one, oblivious of fluctuations. Based on this, we derive a simple and accurate interaction pressure tha ...

Abstract:
... This paper investigated the particle breakage of recycled aggregates from construction and demolition wastes used as subgrade materials. The laboratory tests include two steps, namely, specimen preparation and dynamic triaxial tests. From the view of particle breakage, multiple specimens with different gradations and compositions were analyzed comparatively using two preparation methods, including ...

As the first in-orbit formation satellites equipped with a Laser Ranging Interferometer (LRI) instrument, Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) satellites are designed to evaluate the effective ability of the new LRI ranging system applied to satellite-to-satellite tracking. To evaluate the application of LRI in GRACE-FO, a relative kinematic orbit determination scheme for f ...

Abstract:
... This work reviews the origins, similarities, measurement techniques, and differences of the solvation and nano-colloidal oscillatory structural forces in confined domains. With an increasing confinement, the particles’ structural transition changes from 2D random layering to 2D crystalline packing, as observed experimentally and revealed by the radial distribution function. The 2D in-layer structu ...

Abstract:
... This study examines the relationship between green operations and sustainable quality performance, by incorporating environmental technology as a mediator. Using a sample of 124 firms in Malaysia’s industrial products and service companies, a proposed set of hypotheses are tested using partial least squares structural equation modeling, which allows for consistent analysis. The results show that g ...

Abstract:
... Bio-rhythms are ubiquitous in all living organisms. A prototypical bio-rhythm originates from the chemical oscillation of intermediates or metabolites around the steady state of a thermodynamically open bio-chemical reaction network with autocatalysis and feedback and is often described by minimal kinetics with two state variables. It has been shown that notwithstanding the diverse nature of the u ...

Compared with the Specifications for the seismic design of hydraulic structures (SL203-1997), the standard design response spectrum curve was revised in the new national standard. In order to compare the seismic responses of an arch dam under excitation from the design res ...

Abstract:
... High-dimensional linear models with endogenous variables play an increasingly important role in the recent econometric literature. In this work, we allow for models with many endogenous variables and make use of many instrumental variables to achieve identification. Because of the high-dimensionality in the structural equation, constructing honest confidence regions with asymptotically correct cov ...
