FILIC: Dual-Loop Force-Guided Imitation Learning with Impedance Torque Control for Contact-Rich Manipulation Tasks
Contact-rich manipulation is crucial for robots to perform tasks requiring precise force control, such as insertion, assembly, and in-hand manipulation. However, most imitation learning (IL) policies remain position-centric and lack explicit force awareness, and adding force/torque sensors to collaborative robot arms is often costly and requires additional hardware design. To overcome these issues, we propose FILIC, a Force-guided Imitation Learning framework with impedance torque control. FILI…

A Social Force Model for Companion Groups Considering Relative-Weight Attraction
This paper introduces an improved social force model for companion group that incorporates relative weight attraction. Based on the traditional social force model, the interaction forces among individuals within leader-follower groups are described by introducing relative weight attraction. Additionally, a velocity synchronization term is integrated into the pedestrians' self-driving force to address the problem of group dispersion commonly found in traditional models. Furthermore, the desired …

And if you really want to push candidates left, you do what the Black Panthers did. You provide the service you want to see so the government is forced to play catch up. If you build the world you want to see, you force the state to follow you in order to remain relevant. You make enforcing unjust laws impossible while providing the service to believe should exist. THAT is direct action that wins.
Edit: and that is also shit that will get you killed. If you want to stop fascism, you have to do the real work. Voting can only matter if it's part of a larger strategy to force the system to do what you want. Otherwise you're just legitimizing the managed resistance.

Second-order self-force potential-region binary dynamics at $O(G^5)$ in supergravity
We compute the potential-graviton contributions to the conservative scattering angle of two non-spinning bodies in maximal supergravity at fifth order in Newton's constant, including second-order self-force effects. Our goal is to tackle the challenging integrals arising at this order in Einstein gravity, but within the technically simpler framework of supergravity. The calculation employs the scattering-amplitude framework, effective field theory, and multi-loop integration techniques based on…

It is also important that the gridshell is in equilibrium mainly with axial forces against the design loads; i.e., bending deformation should be avoided. In this study, we first find a conti…

Contact line friction of bubbles
Contact line friction (CLF) of bubbles is ubiquitous, from bubbles on a beer glass to H2 bubbles sliding over electrodes in electrolysis. However, a fundamental understanding of CLF of bubbles is still missing, mainly due to the challenge of precisely controlling bubble sliding. For example, it is not clear how bubbles start sliding and how CLF of bubbles depends on velocity. We therefore developed a bubble friction force instrument to directly measure bubble CLF.

TL;DR: spending money to find the cause of autism is a eugenics project, and those resources could have been spent improving accommodations for Autistic people instead.
To preface this, I'm not Autistic but I'm neurodivergent with some overlap.
We need to be absolutely clear right now: the main purpose is *all* research into the causes of autism is eugenics: a cause is sought because non-autistic people want to *eliminate* autistic people via some kind of "cure." It should be obvious, but a "cured autistic person" who did not get a say in the decision to administer that "cure" has been subjected to non-consensual medical intervention at an extremely unethical level. Many autistic people have been exceptionally clear that they don't want to be "cured," including some people with "severe autism" such as people who are nonverbal.
When we think things like "but autism makes life so hard for some people," we're saying that the difficulties in their life are a result of their neurotype, rather than blaming the society that punished & devalues the behaviors that result from that neurotype at every turn. To the extent that an individual autistic person wants to modify their neurotype and/or otherwise use aids to modify themselves to reduce difficulties in their life, they should be free to pursue that. But we should always ask the question: "what if we changed their social or physical environment instead, so that they didn't have to change themselves?" The point is that difficulties are always the product of person x environment, and many of the difficulties we attribute to autism should instead be attributed to anti-autistic social & physical spaces, and resources spent trying to "find the cause of autism" would be *much* better spent trying to develop & promote better accommodations for autism. Or at least, that's the case if you care about the quality of life of autistic people and/or recognize their enormous contributions to society (e.g., Wikipedia could not exist in anything near its current form without autistic input). If instead you think of Autistic people as gross burdens that you'd rather be rid of, then it makes sense to investigate the causes of autism so that you can eventually find a "cure."
All of that to say: the best response to lies about the causes of autism is to ask "What is the end goal of identifying the cause?" instead of saying "That's not true, here's better info about the causes."
#autism #trump
P.S. yes, I do think about the plight of parents of autistic kids, particularly those that have huge struggles fitting into the expectations of our society. They've been put in a position where society constantly bullies and devalues their kid, and makes it mostly impossible for their kid to exist without constant parental support, which is a lot of work and which is unfair when your peers get the school system to do a massive amount of childcare. But in that situation, your kid is in an even worse position than you as the direct victim of all of that, and you have a choice: are you going to be their ally against the unfair world, or are you going to blame them and try to get them to confirm enough that you can let the school system take care of them, despite the immense pain that that will provoke? Please don't come crying for sympathy if you choose the later option (and yes, helping them be able to independently navigate society is a good thing for them, but there's a difference between helping them as their ally, at their pace, and trying to force them to conform to reduce the burden society has placed on you).

Applying the algorithm to compute alchemical free energies of simple atomistic models shows it can significantly cut the si…

This paper deals with the so-called Boltzmann billiard, that is, a billiard subjected to a central force of the type $V(r)=-α/r-β/r^2$, $α$ and $β$ being positive constants, and with a straight reflection table. In the particular case of $α$ and $β$ positive, we prove the presence of a symbolic dynamics, and hence of positive topological entropy, at positive energy and for $β$ sufficiently small.

Static AdS Black Holes Surrounded by Strings and Quintessence-like Field within Rastall Gravity Framework
In this work, we tested the physical properties of Rastall black holes in the presence of string clouds and quintessence. The modified spacetime geometry arising from the Rastall framework is first established, providing the basis for analyzing the geodesic structure. We study null geodesics in detail, testing photon trajectories, the conditions for photon spheres, BH shadows, the associated effective radial force, and the topological features of photon rings. Also, the analysis is further test…

Measurement of the attractive electrosolvation force between colloidal particles
Direct measurement of the pair interaction potential between electrically like-charged particles in solution reveals a strong and long-ranged attractive force. This counterintuitive attraction has been suggested to arise from the orientation of solvent molecules at the interface between the object and the electrolyte. Here we report measurements of pair interaction potentials between charged microspheres with a range of surface chemistries. We demonstrate that the range of the electrosolvation …

Pose Estimation of a Cable-Driven Serpentine Manipulator Utilizing Intrinsic Dynamics via Physical Reservoir Computing
Cable-driven serpentine manipulators hold great potential in unstructured environments, offering obstacle avoidance, multi-directional force application, and a lightweight design. By placing all motors and sensors at the base and employing plastic links, we can further reduce the arm's weight. To demonstrate this concept, we developed a 9-degree-of-freedom cable-driven serpentine manipulator with an arm length of 545 mm and a total mass of only 308 g. However, this design introduces flexibility…

Coupled Vlasov and non-Newtonian fluid dynamics: existence and large-time behavior
We study a coupled kinetic-non-Newtonian fluid system on the periodic domain ${\mathbb T}^3$, where particles evolve by a Vlasov equation and interact with an incompressible power-law fluid through a drag force. We prove the global existence of weak solutions for all $p > \frac{8}{5}$, where $p > 1$ denotes the power-law exponent of the fluid's stress-strain relation. Under an additional uniform boundedness assumption on the particle density, we also establish large-time decay of a modulated en…

Robust and Resilient Soft Robotic Object Insertion with Compliance-Enabled Contact Formation and Failure Recovery
Object insertion tasks are prone to failures under pose uncertainties and environmental variations, traditionally requiring manual finetuning or controller retraining. We present a novel approach for robust and resilient object insertion using a passively compliant soft wrist that enables safe contact absorption through large deformations, without high-frequency control or force sensing. Our method structures insertion as compliance-enabled contact formations, sequential contact states that pro…

Binary black hole merger in the extreme mass ratio limit: a multipolar analysis of the inclined orbit case
We compute the gravitational waveform emitted during the transition from quasi-spherical inspiral to plunge, merger and ringdown for a system of two black holes in the extreme mass ratio limit, where the primary is spinning and the secondary is represented by a nonspinning point-particle inspiralling along inclined orbits. The point-particle dynamics is described via a Hamiltonian formalism and the transition is driven by an effective-one-body like radiation reaction force. The gravitational wa…

Linear Viscoelasticity of Dilute Solutions of Semiflexible Polymers
The linear viscoelastic response of dilute solutions of semiflexible polymers is studied using Brownian dynamics simulations of coarse-grained bead-spring chains. The springs obey the FENE-Fraenkel force law, a bending potential is used to capture chain stiffness and hydrodynamic interactions are included through the Rotne-Prager-Yamakawa tensor. By calculating the relaxation modulus following a step strain, we demonstrate that the bead-spring chain behaves like an inextensible semiflexible rod…
