description: In June and July of 1998, the Fort Dix Historic Preservation Office (FDHPO) completed a preliminary archaeological investigation in Tactical Training Areas (TTA) 9-13 at Fort Dix. A total of thirteen training areas encompassing about 209 acres were field inspected during this present survey by the FDHPO. This study was performed at the request of the New Jersey Pinelands Commission (NJPC) in order to determine the presence or absence of Euro-American or Native American cultural resources in the study area, and to formulate recommendations concerning the need for further work. The purpose of such additional investigation would be to assess whether any archaeological resources on the property are eligible for listing on the National Register of Historic Places, and evaluate the effect of proposed construction on any such resources. The project area was viewed as archaeologically sensitive by the NJPC and FDHPO because of its association with well-drained soils in relatively close proximity to freshwater streams. In addition, several Native American and Euro-American sites are known to exist relatively close to the project area, according to FDHPO and NJPC site files. Given the heavy degree of ground disturbance, the lack of evidence of Native American activity, and the recent nature of Euro-american (recent army-related) artifactual remains within the study areas, no further cultural resource investigation is recommended.

description: This paper deals with the design of the printhead prototype with extruder which serves for universal processing using several types of materials. It briefly describes the basic principles of FDM technology for which the prototype is designed. The main goal is to explore the possibility of combining 3D printing, and robot technology in order to design a universal printhead, capable of printing from plastic, recycled materials and other substances, including the composites. The proposed concept allows printing oversized objects that are not limited by the relatively small working space compared to commercial FDM devices.

description: Though learning has become a core component of modern information processing, there is now ample evidence that it can lead to biased, unsafe, and prejudiced systems. The need to impose requirements on learning is therefore paramount, especially as it reaches critical applications in social, industrial, and medical domains. However, the non-convexity of most modern statistical problems is only exacerbated by the introduction of constraints. Whereas good unconstrained solutions can often be learned using empirical risk minimization, even obtaining a model that satisfies statistical constraints can be challenging. All the more so, a good one. In this paper, we overcome this issue by learning in the empirical dual domain, where constrained statistical learning problems become unconstrained and deterministic. We analyze the generalization properties of this approach by bounding the empirical duality gap -- i.e., the difference between our approximate, tractable solution and the solution of the original (non-convex) statistical problem -- and provide a practical constrained learning algorithm. These results establish a constrained counterpart to classical learning theory, enabling the explicit use of constraints in learning. We illustrate this theory and algorithm in rate-constrained learning applications arising in fairness and adversarial robustness.

title: A Greedy Heuristic Algorithm for Location-based Group Formation
Creators: name: Sukstrienwong, Anon
Publisher: name: TEM Journal
Year: 2019

description: Presently, location-based Group formation has become more important in many areas. Fundamentally, it is a way to assign all members to suitable groups in order to gain the maximum benefits and accomplish their objectives. However, the process of group formation based on member’s location may cause a problem as it can be time-consuming if the number of members is large and more factors are considered in forming the groups. In order to cope with this problem, we proposed two variants of heuristic algorithm based on greedy algorithm in order to generate the optimized groups of nearby individual members, who are located in different locations. In this paper, we present our experimental results and illustrate that it produces optimal results for small problem sizes. Additionally, the experimental results demonstrated that the greedy algorithms produce the solutions with the intent of finding a global optimum.

description: A matrix factorization problem is considered. The matrix to be factorized is algebraic, has dimension 2 X 2 and belongs to Moiseev's class. A new method of factorization is proposed. First, the matrix factorization problem is reduced to a Riemann-Hilbert problem using the Hurd's method. Secondly, the Riemann-Hilbert problem is embedded into a family of Riemann-Hilbert problems indexed by a variable b taking values on a half-line. A linear ordinary differential equation (ODE1) with respect to b is derived. The coefficient of this equation remains unknown at this step. Finally, the coefficient of the ODE1 is computed. For this, it is proven that it obeys a non-linear ordinary differential equation (ODE2) on a half-line. Thus, the numerical procedure of matrix factorization becomes reduced to two runs of solving of ordinary differential equations on a half-line: first ODE2 for the coefficient of ODE1, and then ODE1 for the unknown function. The efficiency of the new method is demonstrated on some examples.

description: The last decade has been marked by great interest in the dynamics of vortices moving at high ($>$10\,km/s) velocities in superconductors. However, the flux-flow instability (FFI) prevents its exploration and sets practical limits for the use of vortices in various applications. Even so, FFI has turned into a valuable tool for studying the quasiparticle energy relaxation in superconductors, with the view of enhancement of the single-photon detection capability of micrometer-wide strips operated at large bias currents. In this context, the failure of ``global'' FFI models for materials with strong intrinsic and edge vortex pinning has urged the elaboration of ``local'' FFI models. This chapter outlines the recent advances in the research on FFI and highlights superconductors with perfect edges and weak volume pinning as prospective materials for studying fast vortex dynamics and nonequilibrium superconductivity. This manuscript is based on the author-prepared version of the review published in Encyclopedia of Condensed Matter Physics, vol. 2 (2024) 735--754.

description: The process of group decision making requires a set of databases and knowledge bases with coordinated communication between them. A distributed knowledge-based system consists of several knowledge-based systems, and there is a possibility for their physical or logical separation. The article presents the conceptual model of a distributed knowledge-based system. The suggested architecture supports sharing and integration of knowledge and data in addition to allowing heterogeneous knowledge-based systems to communicate with each other. The article also outlines the implementation of interaction protocols comprising intelligent objects which cooperate with each other in order to find solutions to assigned tasks.

description: High precision astrometric Space Very Long Baseline Interferometry (S-VLBI) at the low end of the conventional frequency range, i.e. 20cm, is a requirement for a number of high priority science goals. These are headlined by obtaining trigonometric parallax distances to pulsars in Pulsar--Black Hole pairs and OH masers anywhere in the Milky Way Galaxy and the Magellanic Clouds. We propose a solution for the most difficult technical problems in S-VLBI by the MultiView approach where multiple sources, separated by several degrees on the sky, are observed simultaneously. We simulated a number of challenging S-VLBI configurations, with orbit errors up to 8m in size and with ionospheric atmospheres consistant with poor conditions. In these simulations we performed MultiView analysis to achieve the required science goals. This approach removes the need for beam switching requiring a Control Moment Gyro, and the space and ground infrastructure required for high quality orbit reconstruction of a space-based radio telescope. This will dramatically reduce the complexity of S-VLBI missions which implement the phase-referencing technique.

Russell's typicality as another randomness notion

subject: 03C98, 03D78

description: We reformulate slightly Russell's notion of typicality, so as to eliminate its circularity and make it applicable to elements of any first-order structure. We argue that the notion parallels Martin-Löf (ML) randomness, in the sense that it uses definable sets in place of computable ones and sets of ``small'' cardinality (i.e., strictly smaller than that of the structure domain) in place of measure zero sets. It is shown that if the domain $M$ satisfies $cf(|M|)>\aleph_0$, then there exist $|M|$ typical elements and only $<|M|$ non-typical ones. In particular this is true for the standard model ${\cal R}$ of second-order arithmetic. By allowing parameters in the defining formulas, we are led to relative typicality, which satisfies most of van Lambalgen's axioms for relative randomness. However van Lambalgen's theorem is false for relative typicality. The class of typical reals is incomparable (with respect to $\subseteq$) with the classes of ML-random, Schnorr random and computably random reals. Also the class of typical reals is closed under Turing degrees and under the jump operation (both ways).

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Eutectic high entropy alloys (EHEAs) are emerging as an exciting new class of structural alloys as they have shown very promising mechanical properties. However, how to design these alloys has been a challenge. In this work, a simple approach is presented for designing EHEAs. The introduced approach uses the composition of binary and ternary eutectic alloys for finding the composition of EHEAs. The approach is based on the assumption that EHEAs are originated from binary and ternary eutectic alloys. The approach is applied for alloy systems Al-Co-Cr-Fe-Ni, Co-Cr-Fe-Ni, Co-Cr-Fe-Ni-Ti, and Co-Cr-Fe-Ni-Ta and several EHEAs are predicted for these alloy systems. The predicted results are verified with thermodynamic simulations and experimental data. The results show that the introduced approach can be considered as a feasible and easy-to-use method for designing EHEAs. Based on the developed approach, any binary eutectic alloy can be used for designing multicomponent eutectic alloys.

description: The purpose of this report, a reconnaissance survey of the McGuire Air Defense Missile Site (hereafter referred to generically as BOMARC), is to ascertain if the site, or portions thereof, meet the requirements of the National Register of Historic Places and require compliance with the National Historic Preservation Act of 1966. This report is supplemental to a reconnaissance survey of Cold War properties conducted at McGuire AFB, New Jersey. The main report finds at McGuire AFB, only one group of structures is National Register eligible; the SAGE (Semi Automated Ground Environment) complex. The BOMARC site is found eligible for the NRHP as a district that embodies specific Cold War themes through its design and construction. In plan, in use of materials and method of construction, the BOMARC site is an exceptional example of the quest for technological supremacy over the Soviet Union. Of particular significance is the design and construction of the 84 shelters that housed the missiles. The site contains a significant concentration of interrelated resources that together convey a visual sense of the overall historic environment of a Cold War surface-to-air missile installation. The installation was built and operated as a closed entity, designed to be self-sustaining and continually ready for war. The entire complex is an exceptional example of Cold War material culture. All extant resources considered contributing members to a BOMARC National Register Historic District. The district is also an outstanding example for its associations with the broad patterns of the Cold War, namely the identified themes of technology, national survival, urgency and the use of weapons of mass destruction.
Targeted smoothing parameter selection for estimating average causal effects

name: de Luna, Xavier
Publisher: name: arXiv
Year: 2013
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: The non-parametric estimation of average causal effects in observational studies often relies on controlling for confounding covariates through smoothing regression methods such as kernel, splines or local polynomial regression. Such regression methods are tuned via smoothing parameters which regulates the amount of degrees of freedom used in the fit. In this paper we propose data-driven methods for selecting smoothing parameters when the targeted parameter is an average causal effect. For this purpose, we propose to estimate the exact expression of the mean squared error of the estimators. Asymptotic approximations indicate that the smoothing parameters minimizing this mean squared error converges to zero faster than the optimal smoothing parameter for the estimation of the regression functions. In a simulation study we show that the proposed data-driven methods for selecting the smoothing parameters yield lower empirical mean squared error than other methods available such as, e.g., cross-validation.

On Properties of Non-Markovian Random Walk in One Dimension

Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study a strongly Non-Markovian variant of random walk in which the probability of visiting a given site $i$ is a function $f$ of number of previous visits $v(i)$ to the site. If the probability is proportional to number of visits to the site, say $f(i)=(v(i)+1)^α$ the probability distribution of visited sites tends to be flat for $α>0$ compared to simple random walk. For $f(i)=e^{-v(i)}$, we observe a distribution with two peaks. The origin is no longer the most probable site. The probability is maximum at site k(t) which increases in time. For $f(i)=e^{-v(i)}$ and for $α>0$ the properties do not change as the walk ages. However, for $α<0$, the properties are similar to simple random walk asymptotically. We study lattice covering time for these functions. The lattice covering time scales as $N^{z}$, with $z=2$, for $α \le 0$, $z>2$ for $α >0$ and $z<2$ for $f(i)=e^{-v(i)}$.

In order to apply usability evaluation, two CSP products are used, namely Google Cloud and Microsoft Azure. We have applied usability evaluation method to measure its appropriateness with respect to learning and the use of a product for teaching. We have categorized students in two groups, namely expert and novice. Our evaluation suggests that before using graphical user interfaces of CSP, one should have knowledge and skills in implementing Cybersecurity project.

description: We measured the magneto-reflectivity spectra (4 - 90 meV, 0 - 16 T) of the triple-point semimetal GdPtBi and found them to demonstrate two unusual broad features emerging in field. The electronic bands of GdPtBi are expected to experience large exchange-mediated shifts, which lends itself to a description via effective Zeeman splittings with a large g factor. Based on this approach, along with an ab initio band structure analysis, we propose a model Hamiltonian that describes our observations well and allows us to estimate the effective g factor, g* = 95. We conclude that we directly observe the exchange-induced $Γ_{8}$ band inversion in GdPtBi by means of infrared spectroscopy.

description: Gamma-ray binaries are colliding wind binaries (CWB) composed of a massive star a non-accreting pulsar with a highly relativistic wind. Particle acceleration at the shocks results in emission going from extended radio emission to the gamma-ray band. The interaction region is expected to show common features with stellar CWB. Performing numerical simulations with the hydrodynamical code RAMSES, we focus on their structure and stability and find that the Kelvin-Helmholtz instability (KHI) can lead to important mixing between the winds and destroy the large scale spiral structure. To investigate the impact of the relativistic nature of the pulsar wind, we extend RAMSES to relativistic hydrodynamics (RHD). Preliminary simulations of the interaction between a pulsar wind and a stellar wind show important similarities with stellar colliding winds with small relativistic corrections.

description: Using the Herschel ATLAS science demonstration phase data crossidentified with SDSS DR7 spectra, we select 297 galaxies with F250μm > 5σ. The sample galaxies are classified into five morphological types, and more than 40% of the galaxies are peculiar/compact galaxies. The peculiar galaxies show higher far-infrared/submillimeter luminosity-to-mass ratios than the other types. We perform and analyze the correlations of far-infrared/submillimeter and Hα luminosities for different morphological types and different spectral types. The Spearman rank coefficient decreases and the scatter increases with the wavelength increasing from 100 μm to 500 μm. We conclude that a single Herschel SPIRE band is not good for tracing star formation activities in galaxies. AGNs contribute less to the far-infrared/submillimeter luminosities and do not show a difference from star-forming galaxies. However, the earlier type galaxies present significant deviations from the best fit of star-forming galaxies.

Comparison Theory of Distance Spheres along Geodesics

Publisher: name: Deutsche Mathematiker-Vereinigung

description: Estimates for the principal curvature of distance spheres in Riemannian manifolds with sectional curvature bounded from below are well known. The same holds for the mean curvature of distance spheres in Riemannian manifolds with Ricci curvature bounded from below. In this article we present new estimates for convexity properties of the distance function of a point under different assumptions, for example for manifolds with lower bounds on the conjugate or on the focal radius in addition to these curvature conditions. The main idea is to introduce a new tensor field describing the differential of the exponential map and verifying a Riccati equation. This technique allows us to get new estimates for the volume form and for Jacobi fields in this context but also to gain new insights into well-known comparison theorems.

Exact Solutions and Critical Behaviour for a Linear Growth-Diffusion Equation on a Time-Dependent Domain
Creators: name: Allwright, Jane
Publisher: name: arXiv
Year: 2021
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: A linear growth-diffusion equation is studied in a time-dependent interval whose location and length both vary. We prove conditions on the boundary motion for which the solution can be found in exact form, and derive the explicit expression in each case. Next we prove the precise behaviour near the boundary in a `critical' case: when the endpoints of the interval move in such a way that near the boundary there is neither exponential growth nor decay, but the solution behaves like a power law with respect to time. The proof uses a subsolution based on the Airy function with argument depending on both space and time. Interesting links are observed between this result and Bramson's logarithmic term in the nonlinear FKPP equation on the real line. Each of the main theorems is extended to higher dimensions, with a corresponding result on a ball with time-dependent radius.

description: In this paper, we study thermodynamical properties of the apparent horizon in a universe governed by quasi-topological gravity. Our aim is twofold. First, by using the variational method we derive the general form of Friedmann equation in quasi-topological gravity. Then, by applying the first law of thermodynamics on the apparent horizon, after using the entropy expression associated with the black hole horizon in quasi-topological gravity, and replacing the horizon radius, $r_{+}$, with the apparent horizon radius, $\tilde{r}_{A}$, we derive the corresponding Friedmann equation in quasi-topological gravity. We find that these two different approaches yield the same result which show the profound connection between the first law of thermodynamics and the gravitational field equations of quasi-topological gravity. We also study the validity of the generalized second law of thermodynamics in quasi-topological cosmology. We find that, with the assumption of the local equilibrium hypothesis, the generalized second law of thermodynamics is fulfilled for the universe enveloped by the apparent horizon for the late time cosmology.

Our estimates in particular ensure the invertibility, with quantitative bounds in the frequency, of the merge operators required to reconstruct the original Dirichlet-to-Neumann operator in terms of these impedance-to-impedance operators of the sub-domains. A key step in our proof is to obtain Neumann and Dirichlet boundary trace estimates on solutions of the impedance problem, which are of independent interest. In addition to the variable media setting, we also construct bounds for similar merge operators in the obstacle scattering problem.

description: Her X-1 is one of the the most intensively studied Accreting X-ray Binary Pulsars (AXBPs). This is largely because it is a bright and persistent X-ray pulsar, showing the largest variety of observable phenomena, partly due to the favorable geometry in observing the binary nearly edge-on. Her X-1 is the binary X-ray pulsar in which the first cyclotron line (or Cyclotron Resonant Scattering Feature - CRSF) was detected in 1975. Since then, we have made an effort to observe the source and the CRSF around 40 keV as often as possible, using those X-ray satellites which cover the high energy X-ray range. Extended contributions are from the Rossi X-ray Timing Explorer (RXTE), {INTEGRAL, Suzaku and Swift. The most recent contribution with a new degree of quality is from the high energy imaging telescope on NuStar. We have found that the CRSF is variable with flux, with phase (both pulsational and precessional phase) and with time. The historical evolution of the pulse phase averaged CRSF centroid energy Ecyc since its discovery is characterized by an initial value around 35 keV, an abrupt jump upwards to beyond ~40$ keV between 1990 and 1994 and an apparent secular decay thereafter. Much of this decay, however, was found to be due to an artifact, namely a correlation between Ecyc and the X-ray luminosity Lx discovered in 2007, amounting to a change of ~7% in energy for a factor of two in luminosity. In observations since 2007, however, we now find a statistically significant trend of a true secular decrease of the cyclotron line energy. In addition, we discuss recent results of pulse phase spectroscopy and evidence for the suspected variation in Ecyc with phase of the 35 d precessional period (which is observed both in the modulation of the X-ray flux and in the systematic variation in shape of the 1.24 s pulse profile.

description: The extraction of the finite temperature heavy quark potential from lattice QCD relies on a spectral analysis of the Wilson loop. General arguments tell us that the lowest lying spectral peak encodes, through its position and shape, the real and imaginary part of this complex potential. Here we benchmark this extraction strategy using leading order hard-thermal loop (HTL) calculations. I.e. we analytically calculate the Wilson loop and determine the corresponding spectrum. By fitting its lowest lying peak we obtain the real- and imaginary part and confirm that the knowledge of the lowest peak alone is sufficient for obtaining the potential. Access to the full spectrum allows an investigation of spectral features that do not contribute to the potential but can pose a challenge to numerical attempts of an analytic continuation from imaginary time data. Differences in these contributions between the Wilson loop and gauge fixed Wilson line correlators are discussed. To better understand the difficulties in a numerical extraction we deploy the Maximum Entropy method with extended search space to HTL correlators in Euclidean time and observe how well the known spectral function and values for the real and imaginary part are reproduced. Possible venues for improvement of the extraction strategy are discussed.

description: We investigate the formation process of self-gravitating protoplanetary disks in unmagnetized molecular clouds. The angular momentum is redistributed by the action of gravitational torques in the massive disk during its early formation. We develop a simplified one-dimensional accretion disk model that takes into account the infall of gas from the envelope onto the disk and the transfer of angular momentum in the disk with an effective viscosity. First we evaluate the gas accretion rate from the cloud core onto the disk by approximately estimating the effects of gas pressure and gravity acting on the cloud core. We formulate the effective viscosity as a function of the Toomre Q parameter that measures the local gravitational stability of the rotating thin disk. We use a function for viscosity that changes sensitively with Q when the disk is gravitationally unstable. We find a strong self-regulation mechanism in the disk evolution. During the formation stage of protoplanetary disks, the evolution of the surface density does not depend on the other details of the modeling of effective viscosity, such as the prefactor of the viscosity coefficient. Next, to verify our model, we compare the time evolution of the disk calculated with our formulation with that of three-dimensional hydrodynamical simulations. The structures of the resultant disks from the one-dimensional accretion disk model agree well with those of the three-dimensional simulations. Our model is a useful tool for the further modeling of chemistry, radiative transfer, and planet formation in protoplanetary disks.

description: We generalize the holographic correspondence between topological gravity coupled to an abelian Chern-Simons theory in three dimensions and an ensemble average of Narain's family of massless free bosons in two dimensions, discovered by Afkhami-Jeddi et al. and by Maloney and Witten. We find that the correspondence also works for toroidal orbifolds but not for K3 or Calabi-Yau sigma-models and not always for the minimal models. We conjecture that the correspondence requires that the central charge is equal to the critical central charge defined by the asymptotic density of states of the chiral algebra. For toroidal orbifolds, we extend the holographic correspondence to correlation functions of twist operators by using topological properties of rational tangles in the three-dimensional ball, which represent configurations of vortices associated to a discrete gauge symmetry.

Operator mixing in massless QCD-like theories and Poincare'-Dulac theorem

description: Recently, a geometric approach to operator mixing in massless QCD-like theories -- that involves canonical forms based on the Poincare'-Dulac theorem for the linear system that defines the renormalized mixing matrix in the coordinate representation $Z(x,μ)$ -- has been advocated in arXiv:2103.15527 . As a consequence, a classification of operator mixing in four cases -- depending on the canonical forms of $- \frac{γ(g)}{β(g)}$, with $γ(g)=γ_0 g^2+\cdots$ the matrix of the anomalous dimensions and $β(g)=-β_0 g^3 + \cdots$ the beta function -- has been proposed: (I) nonresonant $\frac{γ_0}{β_0}$ diagonalizable, (II) resonant $\frac{γ_0}{β_0}$ diagonalizable, (III) nonresonant $\frac{γ_0}{β_0}$ nondiagonalizable, (IV) resonant $\frac{γ_0}{β_0}$ nondiagonalizable. In particular, in arXiv:2103.15527 a detailed analysis of the case (I) -- where operator mixing reduces to all orders of perturbation theory to the multiplicatively renormalizable case -- has been provided. In the present paper, following the aforementioned approach, we work out in the remaining three cases the canonical forms for $- \frac{γ(g)}{β(g)}$ to all orders of perturbation theory, the corresponding UV asymptotics of $Z(x,μ)$, and the physics interpretation. We also work out in detail physical realizations of the cases (I) and (II).

description: Jets around low- and intermediate-mass young stellar objects (YSOs) contain a fossil record of the recent accretion and outflow activity of their parent star-forming systems. We aim to understand whether the accretion/ejection process is similar across the entire stellar mass range of the parent YSOs. To this end we have obtained VLT/X-shooter spectra of HH 1042 and HH 1043, two newly discovered jets in the massive star-forming region RCW 36. HH 1042 is associated with the intermediate-mass YSO 08576nr292. Over 90 emission lines are detected in the spectra. High-velocity (up to 220 km/s) blue- and redshifted emission from a bipolar flow is observed in typical shock tracers. Low-velocity emission from the background cloud is detected in nebular tracers, including lines from high ionization species. We applied combined optical and infrared spectral diagnostic tools in order to derive the physical conditions (density, temperature, and ionization) in the jets. The measured mass outflow rates are Mjet ~ 10^-7 Msun/yr. We measure a high accretion rate for HH 1042 (Macc ~ 10^-6 Msun/yr) and Mjet/Macc ~ 0.1, comparable to low-mass sources and consistent with models for magneto-centrifugal jet launching. The knotted structure and velocity spread in both jets are interpreted as fossil signatures of a variable outflow rate. The mean velocities in both lobes of the jets are comparable, but the variations in Mjet and velocity in the two lobes are not symmetric, suggesting that the launching mechanism on either side of the accretion disk is not synchronized. For HH 1042, we have constructed an interpretative physical model with a stochastic or periodic outflow rate and a description of a ballistic flow as its constituents. The knotted structure and velocity spread can be reproduced qualitatively with the model, indicating that the outflow velocity varies on timescales on the order of 100 yr.

Dunkle Materie mit dem Frame-Dragging-Effekt erklärt

description: Mit meiner Verdrängungtheorie habe ich schon etliche Probleme der bekannten Physik gelöst. Ich möchte mit diesem Paper noch zusätzlich einen Weg aufzeigen, wie wir in der Physik auch ohne Dunkle Materie auskommen können. Der Frame-Dragging-Effekt könnte missverstanden und mit zu kurzer Reichweite versehen worden sein. Dieser Effekt reicht höchstwahrscheinlich viel weiter, als man zuerst annehmen würde. Raumzeit wird nicht nur über nahezu unendliche Distanzen gekrümmt, sondern ebenso auch "verdrillt". Eine Gravitation die ewig weit reicht und das selbe Medium manipuliert, muss auch den Effekt des Frame-Dragging genauso weit tragen.
