IFDECORATOR: Wrapping Instruction Following Reinforcement Learning with Verifiable Rewards
Reinforcement Learning with Verifiable Rewards (RLVR) improves instruction following capabilities of large language models (LLMs), but suffers from training inefficiency due to inadequate difficulty assessment. Moreover, RLVR is prone to over-optimization, where LLMs exploit verification shortcuts without aligning to the actual intent of user instructions. We introduce Instruction Following Decorator (IFDecorator}, a framework that wraps RLVR training into a robust and sample-efficient pipeline…

Anyone from Microsoft following me?
I’m going to leave GitHub (I’ve been a user since the beta days) and will incessantly ask everyone I know to leave it as well if you don’t roll back the “can’t opt out” force-feeding of “AI” nonsense.
You should also have no integration or collaboration with Xai at all, ever.
Make your management have some sense, this is hostile and disgusting and wrong.

Feit's conjecture, the canonical Brauer induction formula, and Adams operations
This paper is motivated by a strong version of Feit's conjecture, first formulated by the authors in joint work with A. Kleshchev and P. H. Tiep in 2025, concerning the conductor $c(χ)$ of an irreducible character $χ$ of a finite group $G$. We connect the conjecture with the following construction: For any positive integer $n$ dividing the exponent of $G$ and for any character $χ$ of $G$, we introduce an integer-valued invariant $S(G,χ,n)$ which can be defined as the sum of certain coeffici…

MPC strategies for density profile control with pellet fueling in nuclear fusion tokamaks under uncertainty
Control of the density profile based on pellet fueling for the ITER nuclear fusion tokamak involves a multi-rate nonlinear system with safety-critical constraints, input delays, and discrete actuators with parametric uncertainty. To address this challenging problem, we propose a multi-stage MPC (msMPC) approach to handle uncertainty in the presence of mixed-integer inputs. While the scenario tree of msMPC accounts for uncertainty, it also adds complexity to an already computationally intensive …

In melancholy, the spirits are carried away by an agitation, but a weak agitation that lacks power or violence, a sort of impotent upset that follows neither a particular path nor the aperta opercula [open ways], but traverses the cerebral matter constantly creating new pores. Yet the spirits do not wander far on the new paths they create, and their agitation dies down rapidly, as their strength is quickly spent and motion comes to a halt: ‘non longe perveniunt’ [they do not reach far]. A trouble of this nature, common to all delirium, does not have the power to produce on the surface of the body the violent movements or the cries to be observed in mania and frenzy. Melancholy never attains frenzy; it is a madness always at the limits of its own impotence. That paradox is explained by the secret alterations in the spirits. Ordinarily, they travel with the speed and instantaneous transparency of rays of light, but in melancholy they become weighed down with night, becoming ‘obscure, thick and dark’, and the images of things that they bring before consciousness are ‘in a shadow, or covered with darkness’. As a result they move more slowly, and are more like a dark, chemical vapour than pure light. This chemical vapour is acid in nature, rather than sulphurous or alcoholic, for in acid vapours the particles are mobile and incapable of repose, but their activity is weak and without consequence. When they are distilled, all that remains in the still is a kind of insipid phlegm. Acid vapours, therefore, are taken to have the same properties as melancholy, whereas alcoholic vapours, which are always ready to burst into flames, are more related to frenzy, and sulphurous vapours bring on mania, as they are agitated by continuous, violent movement. If the ‘formal reason and causes’ of melancholy were to be sought, it made sense to look for them in the vapours that rose up from the blood to the head, and which had degenerated into ‘an acetous or sharp distillation’. A cursory glance seems to indicate that a melancholy of spirits and a whole chemistry of humours lies behind Willis’ analyses, but in fact his guiding principle mostly reflects the immediate qualities of the melancholic illness: an impotent disorder, and the shadow that comes over the spirit with an acrid acidity that slowly corrodes the heart and the mind. The chemistry of acids is not an explanation of the symptoms, but a qualitative option: a whole phenomenology of melancholic experience.

Restrictions of PCBNs for integration-free computations
The pair-copula Bayesian Networks (PCBN) are graphical models composed of a directed acyclic graph (DAG) that represents (conditional) independence in a joint distribution. The nodes of the DAG are associated with marginal densities, and arcs are assigned with bivariate (conditional) copulas following a prescribed collection of parental orders. The choice of marginal densities and copulas is unconstrained. However, the simulation and inference of a PCBN model may necessitate possibly high-dimen…

Selective disruption of reach-related saccade timing following a middle-cerebral artery stroke
Background: Coordinated control of eye and hand movements is critical for nearly all goal-directed actions, underpinning tasks ranging from simple object manipulation to complex tool use. This coordination relies on temporal coupling between reach and saccade. Stroke disrupts this process at several levels. Methods: We conducted a comparative eye-tracking study on patients with history of stroke vs. control performing various tasks. We used the Kinereach motion-tracking system with integrated e…
