Voltage-Induced Oxidation for Enhanced Purity and Reproducibility of Quantum Emission in Monolayer 2D Materials
We report a voltage-induced oxidation technique using conductive atomic force microscopy to enhance the single-photon purity and reproducibility of quantum emitters in monolayer tung-sten diselenide (WSe2). By applying a controlled electric field across a monolayer WSe2/poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) on a silicon substrate, localized oxidation is induced around nanoindented emitter sites in the WSe2. This treatment selectively suppresses defect-bound exciton emissi…

ROBBO: An Efficient Method for Pareto Front Estimation with Guaranteed Accuracy
A new method to estimate the Pareto Front (PF) in bi-objective optimization problems is presented. Assuming a continuous PF, the approach, named ROBBO (RObust and Balanced Bi-objective Optimization), needs to sample at most a finite, pre-computed number of PF points. Upon termination, it guarantees that the worst-case approximation error lies within a desired tolerance range, predefined by the decision maker, for each of the two objective functions. Theoretical results are derived, about the wo…

Abstract: Augmenting large language models (LLMs) with external context significantly improves their performance in natural language processing (NLP) tasks. However, LLMs struggle to answer queries reliably when the provided context lacks information, often resorting to ungrounded speculation or internal knowledge. Groundedness - generating responses strictly supported by the context - is essential for ensuring factual consistency and trustworthiness. This study focuses on detecting whether a given query is grounded in a document provided in context before the costly answer generation by LLMs. Such a detection mechanism can significantly reduce both inference time and resource consumption. We show that lightweight, task specific encoder models such as RoBERTa and NomicBERT, fine-tuned on curated datasets, can achieve accuracy comparable to state-of-the-art LLMs, such as Llama3 8B and GPT4o, in groundedness detection while reducing inference latency by orders of magnitude.

From the BC Green Party
Premier David Eby is seriously considering a fossil fuel megaproject that would sell out BC’s energy future to Donald Trump’s corporate allies.
The Prince Rupert Gas Transmission (PRGT) pipeline is backed by MAGA-linked billionaires and would transport fracked gas across Northern BC to a new LNG terminal.
Eby himself once said that we can’t keep building fossil fuel projects and still meet our climate goals. So why is his government even considering t…

Genuinely torn about this. Keeping people safe from a roving right-wing murderer does seem prudent. But I don’t want to send out the message that this is a way to get a protest cancelled.
❝The No Kings coalition that organized protests across the US today is cancelling all demonstrations in Minnesota that have not already started after two lawmakers were shot, Reuters reports.
Indivisible said on Bluesky: “Governor Walz has recommended that we cancel No Kings events across Minnesota because the individual who assassinated a Democratic lawmaker is still at large.”❞

Exploring Strategies for Personalized Radiation Therapy Part II Predicting Tumor Drift Patterns with Diffusion Models
Radiation therapy outcomes are decided by two key parameters, dose and timing, whose best values vary substantially across patients. This variability is especially critical in the treatment of brain cancer, where fractionated or staged stereotactic radiosurgery improves safety compared to single fraction approaches, but complicates the ability to predict treatment response. To address this challenge, we employ Personalized Ultra-fractionated Stereotactic Adaptive Radiotherapy (PULSAR), a strate…
