Shield-Loco: Shielding Locomotion Policies with Predictive Safety Filtering
arXiv:2606.07193v1 Announce Type: new Abstract: Reinforcement learning (RL) policies enable dynamic legged locomotion but lack mechanisms to avoid violations of safety constraints that are absent during training. Large-scale offline safe learning is impractical for covering all edge cases. Existing safety frameworks either rely on reduced-order models that cannot reason about whole-body behaviors or require conservative recovery controllers that degrade task performance.
Linfield's Shields 'pushing to be back for Europe'
Linfield's Shields 'pushing to be back for Europe' - Published Linfield captain Chris Shields said "with a bit of luck" he will be fit to return to the Blues' squad for the upcoming Uefa Conference League qualifiers after missing the majority of last season through injury. Shields has been sidelined since September due to an anterior cruciate ligament (ACL) injury which required surgery. The Blues finished a disappointing fourth in the Irish Premiership, but secured European football this...
UN report: Israeli forces shield settlers during attacks on Palestinians
UN report: Israeli forces shield settlers during attacks on Palestinians UN report: Israeli forces shield settlers during attacks on Palestinians The UN says Israeli security forces routinely accompany settlers and act as a shield for their violence against Palestinians in the occupied West Bank. Israeli officials rejected the report’s findings, saying it relied on unsubstantiated allegations. Published On 10 Jun 2026
US, Shield of the Americas condemn 'ongoing efforts' to overthrow Bolivia's elected president amid unrest
The United States, along with the other countries that make up the Shield of the Americas, condemned the "ongoing efforts" in Bolivia to "overthrow the legitimately and overwhelmingly elected" government of President Rodrigo Paz on Friday. "The member countries of Shield of the Americas denounce ongoing efforts to overthrow the legitimately and overwhelmingly elected government of President Rodrigo Paz in Bolivia," the statement read. "We stand with Paz’s democratic government as it fights...
Easy-to-Use Shielding for Reinforcement Learning
Announce Type: new Abstract: Safe exploration is a key challenge in Reinforcement Learning (RL) that aims to prevent agents from making harmful decisions while exploring their environment. Safe exploration is a key challenge in Reinforcement Learning (RL) that aims to prevent agents from making harmful decisions while exploring their environment. Shielding is one such technique that assumes domain knowledge in the form of an environment model to decide upon action safety.
'Iran was building conventional shield': Rubio defends US war against Tehran at Senate hearing
US secretary of state Marco Rubio on Tuesday defended Washington's military posture toward Iran, arguing that Tehran had been attempting to build up conventional weapons capabilities as a "shield" to protect its nuclear programme. Speaking before the US Senate Foreign Relations Committee, Rubio said Iran’s military capabilities had been significantly weakened following recent US military actions and suggested that its conventional forces were no longer a credible deterrent. "What they tried...
The Map of Parameter Space in Double Microwave Shielding
arXiv:2606.09636v1 Announce Type: cross Abstract: Double microwave shielding employs $\sigma^{+}$- and $\pi$-polarized microwave fields, tuned close to the lowest rotational transition, to engineer a long-range repulsive barrier between polar molecules. By preventing molecules from reaching the short range, this technique suppresses detrimental two-body losses and recently enabled the realization of molecular Bose-Einstein condensates and self-bound droplets. Yet, the optimal operating...
SHIELDS: Automating OS Hardening with Iterative Multi-Agent Remediation
arXiv:2606.05476v1 Announce Type: new Abstract: Security misconfigurations remain a leading cause of OS-level compromise, and manually keeping systems compliant with standards like Defense Information Systems Agency (DISA) Security Technical Implementation Guides (STIGs) is a tedious and expensive process. Existing compliance automation tools can reduce some of this burden, but they depend on static, pre-written corrective actions. In this paper, we introduce SHIELDS, a multi-agent system...
SHIELD: Secure Hypernetworks for Incremental Expansion Learning Defense
Announce Type: replace Abstract: Continual learning under adversarial conditions remains an open problem, as existing methods often compromise either robustness, scalability, or both. We propose a novel framework that integrates Interval Bound Propagation (IBP) with a hypernetwork-based architecture to enable certifiably robust continual learning across sequential tasks. Our method, SHIELD, generates task-specific model parameters via a shared hypernetwork conditioned solely on compact task...
AI: Doctors risk being sued if tools go wrong, while companies are “shielded,” report warns
Doctors are being left exposed to legal claims by a “widening gulf” between the law and the rapidly changing use of artificial intelligence (AI) in healthcare, the Medical Protection Society (MPS) has warned. In its report Closing the AI Liability Gap,1 the medical defence organisation said that doctors and the NHS were currently expected to absorb all legal responsibility for AI use in healthcare, while AI companies were “shielded.”Under
