SLR: Learning Quadruped Locomotion without Privileged Information
Traditional reinforcement learning control for quadruped robots often relies on privileged information, demanding meticulous selection and precise estimation, thereby imposing constraints on the development process. This work proposes a Self-learning Latent Representation (SLR) method, which achieves high-performance control policy learning without the need for privileged information. To enhance the credibility of our proposed method's evaluation, SLR is compared with open-source code repositor…

OCCASO V. Chemical-abundance trends with Galactocentric distance and age
Context. Open clusters provide valuable information on stellar nucleosynthesis and the chemical evolution of the Galactic disc, as their age and distances can be measured more precisely with photometry than for field stars. Aims. Our aim is to study the chemical distribution of the Galactic disc using open clusters by analysing the existence of gradients with Galactocentric distance, azimuth or height from the plane and dependency with age. Methods. High-resolution spectra (R>60 000) of 194 sta…

In September of 2023, the paradigm of Open Access publishing – #SciELO – celebrated its 25-year jubilee, naturally with an Open Access and Open Science themed conference. The link below points to a report, just published, on the session about technologies that enable accessibility.

""Publishing Embargoes and Versions of Preprints: Impact on the Dissemination of Information" @ Open Information Science: #OpenAccess

Who do I know with #arcgis
I did a Freedom of Information request for some data on rights of way and the data sent back appears to be formatted using British National Grid and fooling the online conversion tools.
If I can get the linked results into a GeoJSON format, using lat/lon, I can take it from there!

Data of all of the Maintained Unsurfaced Roads in Norfolk - a Freedom of Information request to Norfolk County Council
I would like an electronic copy of the following rights of way across the Norfolk County: 1. Maintained unsurfaced roads 2. Byways Open to All Traffic I would be happy to receive these in most open formats; GeoJSON, KML, or GPX would be especially helpful. Please ensure that any included rights of way are not subject to a current Traffic Regulation Order, or include a copy of the Traffic Regulation Order documents that are applicable. Yours faithfully, Rachel Lawson

Sam Altman wants to turn #OpenAI into a full for-profit. TBH that would at least be honest: Nothing about what OpenAI does is "open" in any way, shape or form.

Subsystem Information Capacity in Random Circuits and Hamiltonian Dynamics
In this study, we explore the information capacity of open quantum systems, focusing on the effective channels formed by the subsystem of random quantum circuits and quantum Hamiltonian evolution. By analyzing the subsystem information capacity, which is closely linked to quantum coherent information of these effective quantum channels, we uncover a diverse range of dynamical and steady behaviors depending on the types of evolution. Therefore, the subsystem information capacity serves as a valu…

PTHelper: An open source tool to support the Penetration Testing process
Offensive security is one of the state of the art measures to protect enterprises and organizations. Penetration testing, broadly called pentesting, is a branch of offensive security designed to find, rate and exploit these vulnerabilities, in order to assess the security posture of an organization. This process is often time-consuming and the quantity of information that pentesters need to manage might also be difficult to handle. This project takes a practical approach to solve the automation…

Master of Disaster: A Disaster-Related Event Monitoring System From News Streams
The need for a disaster-related event monitoring system has arisen due to the societal and economic impact caused by the increasing number of severe disaster events. An event monitoring system should be able to extract event-related information from texts, and discriminates event instances. We demonstrate our open-source event monitoring system, namely, Master of Disaster (MoD), which receives news streams, extracts event information, links extracted information to a knowledge graph (KG), in th…

Kids of all ages are going to talk about sex whether we like it or not.

Speed limits to the growth of Krylov complexity in open quantum systems
Recently, the propagation of information through quantum many-body systems, developed to study quantum chaos, have found many application from black holes to disordered spin systems. Among other quantitative tools, Krylov complexity has been explored as a diagnostic tool for information scrambling in quantum many-body systems. We introduce a universal limit to the growth of the Krylov complexity in dissipative open quantum systems by utilizing the uncertainty relation for non-hermitian operator…

Differentiable Optics with dLux II: Optical Design Maximising Fisher Information
The design of astronomical hardware operating at the diffraction limit requires optimization of physical optical simulations of the instrument with respect to desired figures of merit, such as throughput or astrometric accuracy. These systems can be high dimensional, with highly nonlinear relationships between outputs and the adjustable parameters of the hardware. In this series of papers we present and apply dLux, an open-source end-to-end differentiable optical modelling framework. Automatic …

Exploring the generation and annihilation of three dimensional nulls through MHD simulations in initially chaotic magnetic field devoid of nulls
Three-dimensional (3D) magnetic nulls are abundant in the solar atmosphere, as been firmly established through contemporary observations. They are established to be important magnetic structures in, for example, jets and circular ribbon flares. While simulations and extrapolations support this, the mechanisms behind 3D null generation remain an open question. Recent magnetohydrodynamics (MHD) simulations propose that magnetic reconnection is responsible for both generating and annihilating 3D n…

On a question of Blecher, Pisier, Shlyakhtenko
We show the failure of a matricial version of Grothendieck's theorem for operator spaces, thereby resolving a long-standing open question in the field. Moreover, by showing that such a counterexample can occur in the simplest context of commutative $C^*$-algebras, we address some other open questions in operator algebras. Our constructions, completely explicit and fairly simple, are inspired by some techniques in quantum information theory.

MuChin: A Chinese Colloquial Description Benchmark for Evaluating Language Models in the Field of Music
The rapidly evolving multimodal Large Language Models (LLMs) urgently require new benchmarks to uniformly evaluate their performance on understanding and textually describing music. However, due to semantic gaps between Music Information Retrieval (MIR) algorithms and human understanding, discrepancies between professionals and the public, and low precision of annotations, existing music description datasets cannot serve as benchmarks. To this end, we present MuChin, the first open-source music…

Statement-Level Vulnerability Detection: Learning Vulnerability Patterns Through Information Theory and Contrastive Learning
Software vulnerabilities are a serious and crucial concern. Typically, in a program or function consisting of hundreds or thousands of source code statements, there are only a few statements causing the corresponding vulnerabilities. Most current approaches to vulnerability labelling are done on a function or program level by experts with the assistance of machine learning tools. Extending this approach to the code statement level is much more costly and time-consuming and remains an open probl…
