description: In a recent paper it was proposed that for some nonlinear shell models of turbulence one can construct a linear advection model for an auxiliary field such that the scaling exponents of all the structure functions of the linear and nonlinear fields coincide. The argument depended on an assumption of continuity of the solutions as a function of a parameter. The aim of this paper is to provide a rigorous proof for the validity of the assumption. In addition we clarify here when the swap of a nonlinear model by a linear one will not work.

The problem with commercial surrogacy. A reflection on reproduction, markets and labour

Subjects: Surrogacy; Market; Labour; Commodification; Freedom.

description: Moral arguments pertaining to commercial surrogate pregnancy have been framed as questions on the appropriate scope of markets. Should pregnancies be conceived and regulated as services that can be exchanged in markets? It has been argued that surrogacy is an exceptional form of labour, and hence inappropriately commodified, because of its nature. Commercial surrogacy involves the bodies and identities of women in a most invasive manner, it negatively affects motherhood and it inappropriately treats babies and surrogates as commodities. We find these arguments wanting: the nature of gestational surrogacy does not make it an exceptional form of labour, and indeed the commodification of pregnancy may disrupt oppressive conceptions of human reproduction. We argue instead that surrogacy does raise major moral concerns insofar as it may exacerbate extant patterns of domination and exploitation based on international inequities and gender-based discrimination. However, the moral problems of surrogacy extend to wage labour more generally. In other words, surrogate pregnancy is not an exceptional form of labour, but human labour is an exceptional commodity.

description: The presence of narrow high-temperature emission lines from nitrogen-rich gas close to SN 1987A has been the principal observational constraint on the evolu- tionary status of the supernova's progenitor. A new analysis of the complete five-year set of low and high resolution IUE ultraviolet spectra of SN 1987A (1987.2--1992.3) provide fluxes for the N V 1240, N IV] 1486, He II 1640, OIII] 1665, NIII] 1751, and CIII] 1908 lines with significantly reduced random and systematic errors and reveals significant short-term fluctuations in the light curves. The N V, N IV] and N III] lines turn on sequentially over 15 to 20 days and show a progression from high to low ionization potential, implying an ioni- zation gradient in the emitting region. The line emission turns on suddenly at 83+/-4 days after the explosion, as defined by N IV]. The N III] line reaches peak luminosity at 399+/-15 days. A ring radius of (6.24+/-0.20)E{17} cm and inclination of 41.0+/-3.9 is derived from these times, assuming a circular ring. The probable role of resonant scattering in the N V light curve introduces systematic errors that leads us to exclude this line from the timing analysis. A new nebular analysis yields improved CNO abundance ratios N/C=6.1+/-1.1 and N/O=1.7+/-0.5, confirming the nitrogen enrichment found in our previous paper. From the late-time behavior of the light curves we find that the emission origi- nates from progressively lower density gas. We estimate the emitting mass near maximum (roughly 400 days) to be roughly 4.7E{-2} solar masses, assuming a filling factor of unity and an electron density of 2.6E4 cm^{-3}. These results are discussed in the context of current models for the emission and hydrodynamics of the ring.

description: Abstract: "Rough surfaces pose a challenging shape extraction problem. Images of rough surfaces are often characterized by high frequency intensity variations, and it is difficult to perceive the shapes of these surfaces from their images. The shape-from-focus method described in this paper uses different focus levels to obtain a sequence of object images. The sum-modified-Laplacian (SML) operator is developed to compute local measures of the quality of image focus. The SML operator is applied to the image sequence, and the set of focus measures obtained at each image point are used to compute local depth estimates.We present two algorithms for depth estimation. The first algorithm simply looks for the focus level that maximizes the focus measure at each point. The other algorithm models the SML focus measure variations at each point as a Gaussian distribution and use this model to interpolate the computed focus measures to obtain more accurate depth estimates. The algorithms were implemented and tested using surfaces of different roughness and reflectance properties. We conclude with a brief discussion on how the proposed method can be applied to smooth textures and smooth non-textured surfaces."

description: We consider perturbative expansions in theories with an infrared cutoff $λ$. The infrared sensitive pieces are defined as terms nonanalytic in the infinitesimal $λ^2$ and powers of this cutoff characterize the strength of these infrared contributions. It is argued that the sum over the initial and final degenerate ( as $λ\to 0$) states which is required by the Kinoshita - Lee - Nauenberg theorem eliminates terms of order $λ^0$ and $λ^1$. However, the quadratic and higher order terms in general do not cancel. This is investigated in simple examples of KLN cancellations, of relevance to the inclusive decay rate of a heavy particle, at the one loop level.

Topological Study of the $H_3^{++}$ Molecular System: $H_3^{++}$ as a Cornerstone for Building Molecules during the Big Bang

description: The present study is devoted to the possibility that tri-atomic molecules were formed during or shortly after the Big Bang. For this purpose we consider the ordinary $H_3^{+}$ and $H_3$ and the primitive tri-atomic molecular system, $H_3^{++}$, which, as is shown, behaves differently. The study is carried out by comparing the topological features of these systems as they are reflected through their non-adiabatic coupling terms. Although the $H_3^{++}$ is not known to exist as a molecule, we found that it behaves as such at intermediate distances. However this illusion breaks down as its asymptotic region is reached. Our study indicates that whereas $H_3^{+}$ and $H_3$ dissociate smoothly, the $H_3^{++}$, does not seem to do so. Nevertheless, the fact that $H_3^{++}$ is capable of living as a molecule on borrowed time enables it to catch an electron and form a molecule via the reaction $H_3^{++} + e \to H_3^{+}$ that may dissociate properly: $H_3^{+} \to H^{+} + H_2$ or $H + H_2^+$. Thus, the two unique features acquired by $H_3^{++}$ namely, that it is the most primitive system formed by three protons and one electron and topologically, still remain for an instant a molecule, may make it the sole candidate for becoming the \bold{cornerstone} for creating the molecules.
The emergence of phase asynchrony and frequency modulation in metacommunities
Creators: name: Guichard, Frederic
name: Zhang, Yuxiang

Publisher: name: My University
Year: 2019

description: Spatial synchrony can summarize complex patterns of population abundance. Studies of phase synchrony predict that limited dispersal can drive either in-phase or out-of-phase synchrony, characterized by a constant phase difference among populations. We still lack an understanding of ecological processes leading to the loss of phase synchrony. Here we study the role of limited dispersal as a cause of phase asynchrony defined as fluctuating phase differences among populations. We adopt a minimal predator-prey model allowing for dispersal-induced phase asynchrony, and show its dependence on species traits. We show that phase asynchrony in a homogeneous metacommunity requires a minimum of three communities and is characterized by the emergence of regional frequency modulation of population fluctuations. This frequency modulation results in spectral signatures in local time series that can be used to infer the causes and properties of metacommunity dynamics. Dispersal-induced phase asynchrony extends the application of ecological theories of synchrony to non stationary time series, and predicts observed spatiotemporal patterns in marine metacommunities.

The inclusion of the higher partial waves is considered. To this end, the method of arXiv:1412.4969 (Meißner et al.) is generalized for the case of unequal masses and arbitrary angular momenta.

Chemical Evolution of Damped Ly alpha galaxies: The [S/Zn] abundance ratio at redshift z > 2

description: Relative elemental abundances, and in particular the alpha/Fe ratio, are an important diagnostic tool of the chemical evolution of damped Ly alpha systems (DLAs). The S/Zn ratio is not affected by differential dust depletion and is an excellent estimator of the alpha/Fe ratio. We report 6 new determinations of sulphur abundance in DLAs at zabs greater than or equal to 2 with already known zinc abundances. The combination with extant data from the literature provides a measure of the S/Zn abundance ratio for a total of 11 high redshift DLA systems. The observed [S/Zn] ratios do not show the characteristic [alpha/Fe] enhancement observed in metal-poor stars of the Milky Way at comparable level of metallicity ([Zn/H] ~ -1). The behaviour of DLAs data is consistent with a general trend of decreasing [S/Zn] ratio with increasing metallicity [Zn/H]. This would be the first evidence of the expected decrease of the alpha/Fe ratio in the course of chemical evolution of DLA systems. However, in contrast to what observed in our Galaxy, the alpha/iron-peak ratio seems to attain solar values when the metallicity is still low ([Zn/H] < -1) and to decrease below solar values at higher metallicities. The behaviour of the alpha/Fe ratio challenges the frequently adopted hypothesis that high redshift DLAs are progenitors of spiral galaxies and favours instead an origin in galaxies characterized by low star formation rates, in agreement with the results from imaging studies of low redshift DLAs, where the candidate DLA galaxies show a variety of morphological types including dwarfs and LSBs and only a minority of spirals.

description: In this paper, we present a filtering method for estimating the shape and end effector pose of a highly articulated surgical snake robot. Our algorithm introduces new kinematic models that are used in the prediction step of an extended Kalman filter whose update step incorporates measurements from a 5-DOF electromagnetic tracking sensor situated at the distal end of the robot. A single tracking sensor is sufficient for estimating the shape of the system because the robot is inherently a follow-the-leader mechanism with well defined motion characteristics. We therefore show that, with appropriate steering motion, the state of the filter is fully observable. The goal of our shape estimation algorithm is to create a more accurate and representative 3D rendered visualization for image-guided surgery.We demonstrate the feasibility of our method with results from an animal experiment in which our shape and pose estimate was used as feedback in a control scheme that semi-autonomously drove the robot along the epicardial surface of a porcine heart.

description: We study the potential of the kinematic SZ effect as a probe for cosmology, focusing on the pairwise method. The main challenge is disentangling the cosmologically interesting mean pairwise velocity from the cluster optical depth and the associated uncertainties on the baryonic physics in clusters. Furthermore, the pairwise kSZ signal might be affected by internal cluster motions or correlations between velocity and optical depth. We investigate these effects using the Magneticum cosmological hydrodynamical simulations, one of the largest simulations of this kind performed to date. We produce tSZ and kSZ maps with an area of $\simeq 1600~\mathrm{deg}^2$, and the corresponding cluster catalogues with $M_{500c} \gtrsim 3 \times 10^{13}~h^{-1}M_\odot$ and $z \lesssim 2$. From these data sets we calibrate a scaling relation between the average Compton-$y$ parameter and optical depth. We show that this relation can be used to recover an accurate estimate of the mean pairwise velocity from the kSZ effect, and that this effect can be used as an important probe of cosmology. We discuss the impact of theoretical and observational systematic effects, and find that further work on feedback models is required to interpret future high-precision measurements of the kSZ effect.

Subjects: human reproductive technology; surrogacy; children; parentage.

description: The overview of practical experiences regarding surrogacy is very various, thus implies different legal choices in order to respect the principle of equality. The multiplicity of situations should induce the Italian lawmakers to address the issue in a new perspective, as the complete prohibition is not a realistic option. Making a com-parison with other States, the essay intends to support the idea of a legal regulation regarding parentage between the child born from surrogacy and the commissioning couple in particular contexts. The logic of absolute ban should be abandoned in certain cases, precisely when the woman who wants to become mother cannot gestate the pregnancy. Exceptionally, the rigid legislative model of motherhood should be put aside, adopting a method based on the continuous reference to the fundamental principles of protection of human rights.

description: In this work, we numerically investigate an experimentally feasible design of a tapered Ne-filled hollow-core anti-resonant fiber and we report the generation of multiple dispersive waves (DWs) in the range 90-120 nm, well into the extreme ultraviolet (UV) region. The simulations assume an 800 nm pump pulse with 30 fs 10 $μ$J pulse energy, launched into a 9 bar Ne-filled fiber with $34~μ$m initial core diameter that is then tapered to a $10~μ$m core diameter. The simulations were performed using a new model that provides a realistic description of both loss and dispersion of the resonant and anti-resonant spectral bands of the fiber, and also importantly includes the material loss of silica in the UV. We show that by first generating solitons that emit DWs in the far-UV region in the pre-taper section, optimization of the following taper structure can allow re-collision with the solitons and further up-conversion of the far-UV DWs to the extreme-UV with energies up to 190 nJ in the 90-120 nm range. This process provides a new way to generate light in the extreme-UV spectral range using relatively low gas pressure.

description: High resolution direct numerical simulations of two-dimensional turbulence in stationary conditions are presented. The development of an energy-enstrophy double cascade is studied and found to be compatible with the classical Kraichnan theory in the limit of extended inertial ranges. The analysis of the joint distribution of energy and enstrophy fluxes in physical space reveals a small value of cross correlation. This result supports many experimental and numerical studies where only one cascade is generated.

The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ recorded by the CMS experiment at the LHC in proton-proton collisions at $\sqrt{s}=$ 13 TeV. Two channels are considered: single top quark FCNC production in association with the Higgs boson (pp $\to$ tH), and top quark pair production with FCNC decay of the top quark (t $\to$ qH). Final states with one isolated lepton and at least three reconstructed jets, among which at least two are associated with b quarks, are studied. No significant deviation is observed from the predicted background. Observed (expected) upper limits at 95% confidence level are set on the branching fractions of top quark decays, $\mathcal{B}$(t $\to$ uH) $

description: Abstract: "As vision systems become more and more complex there is an increasing need to understand the interaction between the various modules that these systems are composed of. In this paper we attempt to answer the question of how a high-level module can feed back its knowledge to a low-level module to improve the performance of the overall system. In particular we consider a system model consisting of a single low-level module that takes a set of low-level parameters as input and a single high-level module that estimates a set of high-level model parameters. We consider the task of setting the low-level parameters to maximize the performance of the overall system. Previous approaches to this problem include setting the parameters by hand, empirical evaluation, learning, and updating the parameters using the previous image in a video. We propose an approach based on simultaneous optimization of the high-level and low-level parameters. After outlining the approach, we demonstrate it on three examples: (1) color-blob tracking, (2) color-based lane tracking, and (3) edge-based lane tracking."

description: Kane and Wells recently argued that collider data point to a Higgsino-like lightest supersymmetric partner which would explain the dark matter in our Galactic halo. They discuss direct detection of such dark-matter particles in laboratory detectors. Here, we argue that such a particle, if it is indeed the dark matter, might alternatively be accessible in experiments which search for energetic neutrinos from dark-matter annihilation in the Sun. We provide accurate analytic estimates for the rates which take into account all relevant physical effects. Currently, the predicted signal falls roughly one to three orders of magnitude below experimental bounds, depending on the mass and coupling of the particle; however, detectors such as MACRO, super-Kamiokande, and AMANDA will continue to take data and should be able to rule out or confirm an interesting portion of the possible mass range for such a dark-matter particle within the next five years.

description: The topic discusses the limitation of charging interest on bank credit operations. It presents the configuration of the price to pay according to the average market interest rate. Regarding the general purpose of this scientific project, is revealed from legal and economic point of view, the applicability of the rule of law and constitutional principles to restrain or limit abusive gains in the financial market in relation to contracts of bank credit. This scientific research, built in six (6) months, using the monographic method, with style of bibliographical research, for the central content and hypotheses are sustained by specialized literature related to the science of law and economics, mostly. As a result, legal (legislation) and technical (interest) aspects are exposed in relation to the charging of interest rates in the Brazilian banking market, with emphasis on concepts and rules that establish an appropriate control of compensatory interest in consumer relations between borrowers and financial institutions, public and private. The principles and rules of the Constitution and Laws and Regulations, in particular the Code of Consumer Protection (CDC - Portuguese initials), which allow the limitation of interest rates are highlighted. Finally, the contribution of this study for the academic and real market (case) shows the legal possibility and need of state intervention (Public Prosecution and Judicial) to curb the easy enrichment of the banks because of our monetary policies and to protect the consumer from the impoverishment with payment of abusive interest.

description: We consider the two- (2D) and three-dimensional (3D) Ising model on a square lattice at the critical temperature $T_c$, under Monte-Carlo spin flip dynamics. The bulk magnetisation and the magnetisation of a tagged line in the 2D Ising model, and the bulk magnetisation and the magnetisation of a tagged plane in the 3D Ising model exhibit anomalous diffusion. Specifically, their mean-square displacement increases as power-laws in time, collectively denoted as $\sim t^c$, where $c$ is the anomalous exponent. We argue that the anomalous diffusion in all these quantities for the Ising model stems from time-dependent restoring forces, decaying as power-laws in time --- also with exponent $c$ --- in striking similarity to anomalous diffusion in polymeric systems. Prompted by our previous work that has established a memory-kernel based Generalised Langevin Equation (GLE) formulation for polymeric systems, we show that a closely analogous GLE formulation holds for the Ising model as well. We obtain the memory kernels from spin-spin correlation functions, and the formulation allows us to consistently explain anomalous diffusion as well as anomalous response of the Ising model to an externally applied magnetic field in a consistent manner.

description: The emergence of Dynamic Mode Decomposition (DMD) as a practical way to attempt a Koopman mode decomposition of a nonlinear PDE presents exciting prospects for identifying invariant sets and slowly decaying transient structures buried in the PDE dynamics. However, there are many subtleties in connecting DMD to Koopman analysis and it remains unclear how realistic Koopman analysis is for complex systems such as the Navier-Stokes equations. With this as motivation, we present here a full Koopman decomposition for the velocity field in Burgers equation by deriving explicit expressions for the Koopman modes and eigenfunctions - the first time this has been done for a nonlinear PDE. The decomposition highlights the fact that different observables can require different subsets of Koopman eigenfunctions to express them and presents a nice example where: (i) the Koopman modes are linearly dependent and so cannot be fit a posteriori to snapshots of the flow without knowledge of the Koopman eigenfunctions; and (ii) the Koopman eigenvalues are highly degenerate which means that computed Koopman modes become initial-condition dependent. As way of illustration, we discuss the form of the Koopman expansion with various initial conditions and assess the capability of DMD to extract the decaying nonlinear coherent structures in run-down simulations.

description: Abstract: "We present a new approach to developing hybrid feedback policies for the control of systems with nonholonomic constraints. We extend the idea of sequential composition and use it to switch between controllers in a state based manner, resulting in a globally convergent, pure feedback policy. Individual controllers in the palette are inspired by variable constraint control. We solve a vision guided unicycle navigation problem and verify the result through simulation and experiment. This technical report presents a detailed description of results published in [10]."

description: Starting from the analysis of the Judgment no. 84/2016 of the Italian Con-stitutional Court, which declared inadmissible the questions as to constitutionality of articles 6, par. 3, and 13, pars 1, 2 and 3, of the Law no. 40/2004, this paper aims to clarify the complex category of not implanted embryos. Through these insights, it fur-ther outlines possible future destinations of not implanted embryos, underlining that they do not always imply «tragic choices» by representative legislator.

description: We incorporate recent calculations of one-loop corrections for the reduced Ioffe-time pseudo-distribution ${\mathfrak M} (ν,z_3^2)$ to extend the leading-logarithm analysis of lattice data obtained by Orginos et al. We observe that the one-loop corrections contain a large term reflecting the fact that effective distances involved in the most important diagrams are much smaller than the nominal distance $z_3$. The large correction in this case may be absorbed into the evolution term, and the perturbative expansion used for extraction of parton densities at the $μ\approx 2$ GeV scale is under control. The extracted parton distribution is rather close to global fits in the $x>0.1$ region, but deviates from them for $x<0.1$.

description: Who decides on Embryo? The Italian ‘Rules Governing Assisted Fertilization’ (L. 40/2004) allows clinical and experimental research on a human embryo only under the condition that therapeutic and diagnostic procedures are conducted to protect the health and development of the embryo itself, and excludes experimentation on embryos (art. 13 L. 40/2004). Recently, this article has been offered to the Italian Constitutional Court’s consideration (C.C. 84/2016), under the lens of a balancing text between the freedom of research and the protection of human dignity. The legal and philosophical construction of what (or who) an embryo is, in its relation with human dignity, is very interesting to analyze. In this sense, the Italian Constitutional Court’s judgment is crucial, because of the particular interpretation of the Aristotelian argument, often spent in this topic, but even for the boundaries that it poses between law and science in defining the theoretical and legal status of the embryo.

description: Because of the significant development in demand for mobile communications, there has been a lot of study into making optimal use of the limited spectrum available for cellular communications. The authors propose a novel call admission control mechanism, DCAS (Dynamic Channel Allocation Scheme), in this work. The number of guard channel(s) is automatically modified in this new method based on the average handoff blocking rate observed over a given period of time. The handoff blocking rate is kept below the set limit, and the new call blocking rate is kept to a minimum. Simulation of nodes is used to evaluate the DCAS's performance. The DCAS method surpasses the Static Channel Allocation Scheme by setting a strict limitation on the likelihood of handoff rejection. The suggested approach provides the best results by optimizing resource consumption and dynamically adapting to changing traffic circumstances.

description: This paper describes mechanisms used by humans to stand on moving platforms, such as a bus or ship, and to combine body orientation and motion information from multiple sensors including vision, vestibular, and proprioception. A simple mechanism, sensory re-weighting, has been proposed to explain how human subjects learn to reduce the effects of a moving support platform on balance. Our goal is to replicate this robust balance behavior in bipedal robots. We present results exploring sensory re-weighting in humans, simulation, and in a robot implementation.

description: In this paper we study the theoretical uncertainties in the determination of the top-quark mass using next-to-leading-order (NLO) generators interfaced to parton showers (PS) that have different levels of accuracy. Specifically we consider three generators: one that implements NLO corrections in the production dynamics, one that includes also NLO corrections in top decay in the narrow width approximation, and one that implements NLO corrections for both production and decay including finite-width and interference effects. Since our aim is to provide an assessment of the uncertainties of purely theoretical origin, we consider simplified top-mass related observables that are broadly related to those effectively used by experiments, eventually modelling experimental resolution effects with simple smearing procedures. We estimate the differences in the value of the extracted top mass that would occur due to the use of the three different NLO generators, to the variation of scales, to the choice of parton distribution functions and to the matching procedure. Furthermore, we also consider differences due to the shower and to the modelling of non-perturbative effects by interfacing our NLO generators to both Pythia8.2 and Herwig7.1, with various settings. We find very different results depending upon the adopted shower model. While with Pythia8.2 we find moderate differences between the different NLO+PS generators, with Herwig7.1 we find very large ones. Furthermore, the differences between Pythia8.2 and Herwig7.1 generators are also remarkably large.

The general solution of the matrix equation $w_t+\sum\limits_{k=1}^nw_{x_k}ρ^{(k)}(w)=ρ(w)+[w,T\tildeρ(w)]$

description: We construct the general solution of the equation $w_t+\sum\limits_{k=1}^nw_{x_k}ρ^{(k)}(w)=ρ(w)+[w,T\tildeρ(w)]$, for the $N\times N$ matrix $w$, where $T$ is any constant diagonal matrix, $n, N \in \NN_+$ and $ρ^{(k)}, ρ, \tildeρ: \RR \to \RR$ are arbitrary analytic functions. Such a solution is based on the observation that, as $w$ evolves according to the above equation, the evolution of its spectrum decouples, and it is ruled by the scalar analogue of the above equation. Therefore the eigenvalues of $w$ and suitably normalized eigenvectors are the $N^2$ Riemann invariants. We also obtain, in the case $ρ=\tildeρ=0$, a system of $N^2$ non-differential equations characterizing such a general solution. We finally discuss reductions of the above matrix equation to systems of $N$ equations admitting, as Riemann invariants, the eigenvalues of $w$. The simplest example of such reductions is a particular case of the gas dynamics equations

description: The algorithm "automated compression of environments" (ACE) [Nat. Phys. 18, 662 (2022)] provides a versatile way of simulating an extremely broad class of open quantum systems. This is achieved by encapsulating the influence of the environment, which is determined by the interaction Hamiltonian(s) and initial states, into compact process tensor matrix product operator (PT-MPO) representations. The generality of the ACE method comes at high numerical cost. Here, we demonstrate that orders-of-magnitude improvement of ACE is possible by changing the order of PT-MPO contraction from a sequential to a tree-like scheme. The problem of combining two partial PT-MPOs with large inner bonds is solved by a preselection approach. The drawbacks of the preselection approach are that the MPO compression is suboptimal and that it is more prone to error accumulation than sequential combination and compression. We therefore also identify strategies to mitigate these disadvantages by fine-tuning compression parameters. This results in a scheme that is similar in compression efficiency and accuracy to the original ACE algorithm, yet is significantly faster. Our numerical experiments reach similar conclusions for bosonic and fermionic test cases, suggesting that our findings are characteristic of the combination of PT-MPOs more generally.
Hydrodynamic stress correlations in fluid films driven by stochastic surface forcing

description: We study hydrodynamic fluctuations in a compressible and viscous fluid film confined between two rigid, no-slip, parallel plates, where one of the plates is kept fixed, while the other one is driven in small-amplitude, translational, displacements around its reference position. This jiggling motion is assumed to be driven by a stochastic, external, surface forcing of zero mean and finite variance. Thus, while the transverse (shear) and longitudinal (compressional) hydrodynamic stresses produced in the film vanish on average on either of the plates, these stresses exhibit fluctuations that can be quantified through their equal-time, two-point, correlation functions. For transverse stresses, we show that the correlation functions of the stresses acting on the same plate (self-correlators) as well as the correlation function of the stresses acting on different plates (cross-correlators) exhibit universal, decaying, power-law behaviors as functions of the inter-plate separation. At small separations, the exponents are given by -1, while at large separations, the exponents are found as -2 (self-correlator on the fixed plate), -4 (excess self-correlator on the mobile plate) and -3 (cross-correlator). For longitudinal stresses, we find much weaker power-law decays in the large separation regime, with exponents -3/2 (excess self-correlator on the mobile plate) and -1 (cross-correlator). The self-correlator on the fixed plate increases and levels off upon increasing the inter-plate separation, reflecting the non-decaying nature of the longitudinal forces acting on the fixed plate.
