Tonight the MPs will debate and vote upon a law to send refugees to Rwanda. Not people who they claim aren't refugees. Just actual refugees.
They sold it as "for processing there" initially, but in fact it's just send them there never to return.
At a cost of over a million pounds per refugee.
Since the courts found that Rwanda might not be safe, the law they will debate declares that it is in fact safe. Even if a civil war breaks out tomorrow, even if a volcano turns the whole country into a lava-floor, it'll still be legally safe according to our MPs.
They seem to think that the Parliament is some kind of supreme body able to define and enforce the nature of truth, rather than being just one of many institutions of state which are set up to compete with checks and balances in order to prevent tyranny.
I can't think of a more obvious demonstration that the house has lots it's wits entirely and has become crazed with power.
They think they can legislate truth, and should have no legal restraints upon them.
You'd hope an election soon will remove them, but the opposition, Labour, are fine with it, so long as it doesn't include our military collaborators. They have an amendment saying it's fine to send everyone I guess, except not those who collaborated with our military.
What a broken country. We need to disband Westminster, really, it's become corrupt beyond redemption.

Measuring the Substructure Mass Power Spectrum of 23 SLACS Strong Galaxy-Galaxy Lenses with Convolutional Neural Networks
Strong gravitational lensing can be used as a tool for constraining the substructure in the mass distribution of galaxies. In this study we investigate the power spectrum of dark matter perturbations in a population of 23 Hubble Space Telescope images of strong galaxy-galaxy lenses selected from The Sloan Lens ACS (SLACS) survey. We model the dark matter substructure as a Gaussian Random Field perturbation on a smooth lens mass potential, characterized by power-law statistics. We expand upon th…

Evolutionary Period Changes For 52 Cataclysmic Variables, and the Failure For the Most Fundamental Prediction of the Magnetic Braking Model
The evolution of Cataclysmic Variables (CVs) is driven by period-changes ($\dot{P}$), for which the long-venerable consensus is the Magnetic Braking Model (MBM). The MBM has its only distinctive assumption being a power-law `recipe' describing the angular momentum loss (AML) in the binary, producing a single unique evolutionary track with $\dot{P}$ as a function of the orbital period. This required prediction can be used to test the most-fundamental assumption of MBM, but it has never been test…

Multidisperse Random Sequential Adsorption and Generalizations
In this paper, we present a unified study of the limiting density in one-dimensional random sequential adsorption (RSA) processes where segment lengths are drawn from a given distribution. In addition to generic bounds, we are also able to characterize specific cases, including multidisperse RSA, in which we draw from a finite set of lengths, and power-law RSA, in which we draw lengths from a power-law distribution.

A comparison between axion-like and power law potentials in cosmological background
In this paper, we compare the scalar field dynamics in axion-like and power law potentials for both positive and negative values of the exponents. We find that, for positive exponents, both the potentials exhibit similar scalar field dynamics and it can be difficult to distinguish them at least at the background level. Even though the potentials are oscillatory in nature for positive exponents scaling solutions can be achieved for larger values of the exponent for which the dynamics can be diff…

Deformation of power law in the double Pareto distribution using uniformly distributed observation time
The double Pareto distribution is a heavy-tailed distribution with a power-law tail, that is generated via geometric Brownian motion with an exponentially distributed observation time. In this study, we examine a modified model wherein the exponential distribution of the observation time is replaced with a continuous uniform distribution. The probability density, complementary cumulative distribution, and moments of this model are exactly calculated. Furthermore, the validity of the analytical …

The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution.

A non-singular universe out of Hayward black hole
We construct a (quantum mechanically) modified model for the Oppenheimer-Snyder collapse scenario where the exterior of the collapsing dust ball is a Hayward black hole spacetime and the interior is a dust Friedmann-Robertson-Walker cosmology. This interior cosmology is entirely determined by the junction conditions with the exterior black hole. It turns out to be non-singular, displaying a power-law contraction which precedes a de Sitter phase or, reversely, a power-law expansion followed by a…

Dipolar order controls dielectric response of glass-forming liquids
The dielectric response of liquids reflects both, reorientation of single molecular dipoles and collective modes, i.e., dipolar cross-correlations. A recent theory predicts the latter to produce an additional slow peak in the dielectric loss spectrum. Following this idea we argue that in supercooled liquids the high-frequency power law exponent of the dielectric loss $β$ should be correlated with the degree of dipolar order, i.e., the Kirkwood correlation factor $g_K$. This notion is confirmed…

For any $0 < n < d+2$, we obtain the ground-state energy $E_N$ of the system perturbatively in $ε$, $E_{N}=E_{N}^{\left(0\right)}+εE_{N}^{\left(1\right)}+O\left(ε^{2}\right)$.

Optimal Real Time Drone Path Planning for Harvesting Information from a Wireless Sensor Network
We consider a remote sensing system in which fixed sensors are placed in a region, and a drone flies over the region to collect information from cluster heads. We assume that the drone has a fixed maximum range, and that the energy consumption for information transmission from the cluster heads increases with distance according to a power law. Given these assumptions, we derive local optimum conditions for a drone path that either minimizes the total energy or the maximum energy required by the…

Scaling Law Breaking in Unequal-size Droplet Coalescence
This Letter examines the coalescence of two unequal-size spherical liquid droplets in the inviscid regime. We find that the liquid bridge evolution exhibits a breaking from the classical 1/2 power-law scaling [Phys. Rev. Lett. 95, 164503 (2005)]. Employing an energy balance analysis, we attain a theoretical model to collapse bridge evolution data of different droplet size ratios. This model reveals an exponential dependence of the bridge's radial growth on time, which is intrinsically scaling-f…

Throughout history most young adults have chosen to live where their parents did while a smaller number moved away. This is sufficient, by proof and simulation, to account for the well-known power law distributions of city sizes. The model needs only two parameters, $r$ = the probability that a child stays, and the maximum number of cities (which models the observed saturation at high city rank). The power law exponent follows directly as $α= 1 + 1/r$, with Zipf's Law simply the limiting case …

Mekler's Construction and Murphy's Law for 2-Nilpotent Groups
Mekler's construction is a powerful technique for building purely algebraic structures from combinatorial ones. Its power lies in the fact that it allows various model-theoretic tameness properties of the combinatorial structure to transfer to the algebraic one. In this paper, we push this ideology much further, describing a broad class of properties that transfer through Mekler's construction. This technique subsumes many well-known results and opens avenues for many more. As a straightforwa…

Capillary levelling of thin liquid films of power-law rheology
We find solutions that describe the levelling of a thin fluid film, comprising a non-Newtonian power-law fluid, that coats a substrate and evolves under the influence of surface tension. We consider the evolution from both periodic and localised initial conditions as separate cases. Particular (similarity) solutions in each of these two cases exhibit the generic property that the profiles are weakly singular (that is, higher-order derivatives do not exist), at points where the pressure gradient…

Statistical analysis of pulsar flux density distribution
This study presents a comprehensive analysis of the spectral properties of 886 pulsars across a wide frequency range from 20MHz to 343.5GHz, including a total of 86 millisecond pulsars. The majority of the pulsars exhibit power-law behavior in their spectra, although some exceptions are observed. Five different spectral models, namely simple power-law, broken power-law, low-frequency turn-over, high-frequency cut-off, and double turn-over, were employed to explore the spectral behaviors. The av…

FlowWalker: A Memory-efficient and High-performance GPU-based Dynamic Graph Random Walk Framework
Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within a graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand a pre-processing buffer, causing substantial space complexity. Moreover, the power-law distribution of graph vertex degrees introduces workload imbalance issues, rendering DGRW embarrassed to parallelize. In this paper, we propose FlowWalker, a GPU-based dynamic graph random walk fra…

Tight Convergence Rate Bounds for Optimization Under Power Law Spectral Conditions
Performance of optimization on quadratic problems sensitively depends on the low-lying part of the spectrum. For large (effectively infinite-dimensional) problems, this part of the spectrum can often be naturally represented or approximated by power law distributions, resulting in power law convergence rates for iterative solutions of these problems by gradient-based algorithms. In this paper, we propose a new spectral condition providing tighter upper bounds for problems with power law optimiz…

Superior Genetic Algorithms for the Target Set Selection Problem Based on Power-Law Parameter Choices and Simple Greedy Heuristics
The target set selection problem (TSS) asks for a set of vertices such that an influence spreading process started in these vertices reaches the whole graph. The current state of the art for this NP-hard problem are three recently proposed randomized search heuristics, namely a biased random-key genetic algorithm (BRKGA) obtained from extensive parameter tuning, a max-min ant system (MMAS), and a MMAS using Q-learning with a graph convolutional network. We show that the BRKGA with two simple …

Implications of GWTC-3 on primordial black holes from vacuum bubbles
The population of black holes inferred from the detection of gravitational waves by the LIGO-Virgo-KAGRA Collaboration has revealed interesting features in the properties of black holes in the Universe. We analyze the GWTC-3 dataset assuming the detected black holes in each event had an either astrophysical or primordial origin. In particular, we consider astrophysical black holes described by the fiducial \textsc{Power Law + Peak} distribution and primordial black holes whose mass function obe…

Linking Invariants for Valuations and Orderings on Fields
The mod-2 arithmetic Milnor invariants, introduced by Morishita, provide a decomposition law for primes in canonical Galois extensions with unitriangular Galois groups, and contain the Legendre and Redei symbols as special cases. Morishita further proposed a notion of mod-q arithmetic Milnor invariants, where q is a prime power, for number fields containing the q-th roots of unity and satisfying certain class field theory assumptions. We extend this theory from the number field context to gener…

A logarithm law for nonautonomous systems fastly converging to equilibrium and mean field coupled systems
We prove that if a nonautonomous system has in a certain sense a fast convergence to equilibrium (faster than any power law behavior) then the time $τ_{r}(x,y)$ needed for a typical point $x$ to enter for the first time in a ball $B(y,r)$ centered in $y$, with small radius \ $r $ scales as the local dimension of the equilibrium measure \ $μ$ at $y$, i.e. $$ \underset{r\rightarrow 0}{\lim }\frac{\log τ_{r}(x,y)}{-\log r}% =d_{μ}(y).$$ We then apply the general result to concrete systems of…

Conformal and Non-Minimal Couplings in Fractional Cosmology
Fractional differential calculus is a mathematical tool that has found applications in the study of social and physical behaviors considered ``anomalous''. It is often used when traditional integer derivatives models fail to represent cases where the power law is observed accurately. Fractional calculus must reflect non-local, frequency- and history-dependent properties of power-law phenomena. This tool has various important applications, such as fractional mass conservation, electrochemical an…

These processes exhibit a power law tail of the form $n^{-(1+α)}$, with $α\in (\frac{1}{2}, 1)$, where the $\ell^1$ norm of the kernel vector is close to $1$. The result is in contrast to scaling limit of the continuous-time heavy tailed unstable Hawkes processes and the one of INAR($p$) processes. We show that the discrete-time scaling limit also has long-memory property and can als…

Revisiting the effect of lens mass models in cosmological applications of strong gravitational lensing
Strong gravitational lens system catalogues are typically used to constrain a combination of cosmological and empirical lens mass model parameters, even though the simplest singular isothermal sphere (SIS) models yield a $χ^2$ per degree of freedom $\simeq 2$. To date, this problem has been alleviated by introducing additional empirical parameters in the extended power law (EPL) models and constraints from high resolution imagery. The EPL parameters are taken to vary from lens to lens, rather …

Epidemic modelling requires knowledge of the social network
Compartmental models of epidemics are widely used to forecast the effects of communicable diseases such as COVID-19 and to guide policy. Although it has long been known that such processes take place on social networks, the assumption of random mixing is usually made, which ignores network structure. However, super-spreading events have been found to be power-law distributed, suggesting that the underlying networks may be scale free or at least highly heterogeneous. The random-mixing assumption…

We show that for such systems where the ranks of the augmented matrices containing the kinetic order vectors of the underlying subnetworks sum up to the rank of the augmented matrix containing the kinetic order vectors of the entire network, then the existence of the p…

Complex angular structure of three elliptical galaxies from high-resolution ALMA observations of strong gravitational lenses
The large-scale mass distributions of galaxy-scale strong lenses have long been assumed to be well-described by a singular ellipsoidal power-law density profile with external shear. However, the inflexibility of this model could lead to systematic errors in astrophysical parameters inferred with gravitational lensing observables. Here, we present observations with the Atacama Large (sub-)Millimetre Array (ALMA) of three strongly lensed dusty star-forming galaxies at $\simeq30$ mas angular resol…

Peak energy--Isotropic Luminosity Correlation and Jet Opening Angle Evolution in Swift-BAT Short GRBs with Soft Tail Emission
Some short gamma-ray bursts (SGRBs) exhibit a short duration and spectral hard emission (referred to as a "hard spike") followed by a slightly longer soft emission (known as a "soft tail"). We identified nine SGRBs with known redshift in the \textit{Swift}/BAT gamma-ray burst catalog by specifically searching for the soft tail. We found that spectra of these SGRBs can be described as a cutoff power-law model for both hard spike and soft tail, and both show time variation keeping the $E_{\rm pea…

In the first part of the article, we study one-dimensional noninteracting fermions in the continuum and in the presence of the repulsive inverse power law potential, with an emphasis on the Wigner function in the semiclassical limit. In this limit, the Wigner function exhibits an edge called the Fermi surf that depends only on the classical one-particle Hamiltonian. Around the Fermi surf, under a well-defined semiclassical limit, the Wigner function can be expressed in terms of Airy functions w…

Non-Monotonic Relations of Galaxy Star Formation, Radius, and Structure at Fixed Stellar Mass
We investigate the relation between galaxy structure and star formation rate (SFR) in a sample of $\sim2.9\times10^{4}$ central galaxies with $z<0.0674$ and axial ratios $b/a>0.5$. The star-forming main sequence (SFMS) shows a bend around the stellar mass of $M_\ast\leq{}M_c=2\times10^{10}{}M_{\odot}$. At $M_\ast\leq{}M_c$ the SFMS follows a power-law $\text{SFR}\propto{}M_\ast^{0.85}$, while at higher masses it flattens. $M_c$ corresponds to a dark matter halo mass of $M_\text{vir}\sim{}10^{11…
