A thalamus–brainstem attractor network drives history-biased decisions

Abstract Natural environments often change gradually, making it adaptive to bias decisions on the basis of the recent past — a phenomenon known as serial dependence1,2,3. Large-scale recordings during behaviour have identified that serial dependence is a common motif for decision-making, with neural representations of past experiences found throughout the brain4,5,6,7,8,9,10,11. However, it remains unclear whether this bias arises from dedicated neural circuits with history-specific...

Bhutan experiences 5.8-magnitude earthquake; tremors felt in parts of Northeast India

A magnitude 5.8 earthquake struck Bhutan late on Sunday night, triggering multiple aftershocks and sending tremors across parts of Northeast India, according to the National Centre for Seismology (NCS). The earthquake occurred at 11.06pm IST at a depth of 26km, with its epicentre located in Bhutan. The epicentre was about 252km from parts of Assam, and tremors were felt in several areas across India's northeastern region following the quake.

Discrete Incremental Voting: New Bounds for General Graphs and Expanders

arXiv:2606.06381v1 Announce Type: new Abstract: We analyze the discrete incremental voting process (DIV) introduced by Cooper, Radzik, and Shiraga [OPODIS '23]. In this process, we consider a set $V$ of $n$ nodes connected in an undirected graph $G = (V, E)$ where each node has an integer opinion. In one step a randomly selected node interacts with its randomly selected neighbor and changes its opinion by $1$ in the direction of the neighbour's opinion.

Multi-feature Classification to Improve Colorimetric Loop-Mediated Isothermal Amplification Fidelity

Loop-mediated isothermal amplification (LAMP) is a cost-effective and portable assay technique for performing nucleic acid-based diagnostics in the field whose adoption is hindered by design and reproducibility issues. This is due to a complex primer design process that fine-tunes parameters across 6-8 binding regions. The likelihood of assay success depends on satisfying thermodynamic and secondary structure constraints while maintaining target specificity and avoiding overlaps between...

CLSP-REQA: A Real-Time Quality-Aware Closed-Loop Seizure Prediction Framework with Mamba-BiLSTM and Confidence-Gated Intervention

arXiv:2606.00074v1 Announce Type: cross Abstract: Reliable seizure prediction is a prerequisite for closed-loop neurostimulation therapy, yet existing methods rarely account for the variability in EEG signal quality encountered in real-world deployment, and the overwhelming majority adopt non-strict evaluation protocols that overestimate generalisation performance. We propose CLSP-REQA (Closed-Loop Seizure Prediction with Real-time EEG Quality Assessment), a unified framework that embeds a...

From Attack Simulation to SIEM Rule: Deterministic Detection-as-Code Synthesis with Probe-Level Traceability

Announce Type: new Abstract: Security teams routinely simulate attacks against their own systems to check whether their monitoring would catch a real intruder. These Breach-and-Attack-Simulation (BAS) tools surface findings, but the security information and event management (SIEM) systems that watch production need detection rules -- and today a human bridges that gap by hand, reading each finding and writing the corresponding Sigma rule (a vendor-neutral detection format). We show this...

Deterministic Monotone Min-Plus Product and Convolution

arXiv:2605.07150v2 Announce Type: replace Abstract: The Monotone Min-Plus Product problem is a useful primitive that has seen many algorithmic applications over the past decade. In this problem, we are given two $n\times n$ integer matrices $A$ and $B$, where each row of $B$ is a monotone non-decreasing sequence of integers from $\{1,\dots,n\}$, and the goal is to compute their Min-Plus product, defined as the $n\times n$ matrix $C$ with $C_{i,j} = \min_{k}\{A_{i,k} + B_{k,j}\}$. The fastest...

The Security Budget of Code LLMs: An Information-Theoretic Capacity-Security Bound

Announce Type: new Abstract: AI programming assistants make natural-language prompts a software-development interface, so small prompt perturbations become usability and security risks. We study an information-theoretic trade-off for code LLMs between functional capacity, $\Cap=\rmI(c^*;c_\pi)$, and perturbation retention, $\Sec=\rmI(c_\pi;\tilde c_\pi)$. Here $\Sec$ is a retention-channel quantity, not a direct measure of exploit success or vulnerable-code generation. For code completion...

Delaney Hall snack purchases cast doubt on hunger strike reports, DHS says

Revenue figures from the Delaney Hall ICE detention center’s commissary may undercut Democrats’ claims that a reported "hunger strike" is rippling through the Newark facility, as commissary spending surged during the reported strike period. A slew of Democrats have toured the facility and reported allegedly dire conditions and rotten food, but a source familiar with Delaney Hall’s operations disputed their claims. The source said Delaney Hall’s commissary — where inmates can purchase snacks...
