Encoding call-by-push-value in the pi-calculus
In this report we define an encoding of Levys call-by-push-value lambda-calculus (CBPV) in the pi-calculus, and prove that our encoding is both sound and complete. We present informal (by-hand) proofs of soundness, completeness, and all required lemmas. The encoding is specialized to the internal pi-calculus (pi-i-calculus) to circumvent certain challenges associated with using de Bruijn index in a formalization, and it also helps with bisimulation as early-, late- and open-bisimulation coincid…

When Detection Fails: The Power of Fine-Tuned Models to Generate Human-Like Social Media Text
Detecting AI-generated text is a difficult problem to begin with; detecting AI-generated text on social media is made even more difficult due to the short text length and informal, idiosyncratic language of the internet. It is nonetheless important to tackle this problem, as social media represents a significant attack vector in online influence campaigns, which may be bolstered through the use of mass-produced AI-generated posts supporting (or opposing) particular policies, decisions, or event…

Towards Solving More Challenging IMO Problems via Decoupled Reasoning and Proving
Automated Theorem Proving (ATP) in formal languages is a foundational challenge for AI. While Large Language Models (LLMs) have driven remarkable progress, a significant gap remains between their powerful informal reasoning capabilities and their weak formal proving performance. Recent studies show that the informal accuracy exceeds 80% while formal success remains below 8% on benchmarks like PutnamBench. We argue this gap persists because current state-of-the-art provers, by tightly coupling r…

Good Morning #Canada
#HappyBirthday to Peter Gzowski, one of Canada’s most beloved broadcasters. He was born in Toronto in 1934 and raised in Galt, Ontario. At the University of Toronto, he edited the school newspaper, The Varsity, and developed his passion for journalism. A born storyteller, he worked at newspapers in Timmins, Moose Jaw, and Chatham. In 1958, he joined Maclean’s where he became the magazine’s youngest ever managing editor in 1962. He was best known as the host of the CBC Radio's Morningside, the program that earned him the informal title of Captain Canada. Canadians from coast to coast to coast responded to his folksy style of interviewing everyone from Prime Ministers to celebrities. It is estimated that over his career, Peter Gzowski conducted some 30,000 interviews.

What's the preferred easy-to-use benchmarking tool these days for testing full HTTP responses? I know ab (apache bench), but it's also very old so I assume there's a new favorite.
This is for mostly informal tests, so ease of use > capability. Must run on Linux CLI.

DAIEM: Decolonizing Algorithm's Role as a Team-member in Informal E-market
In Bangladesh's rapidly expanding informal e-market, small-scale sellers use social media platforms like Facebook to run businesses outside formal infrastructures. These sellers rely heavily on platform algorithms, not just for visibility, but as active collaborators in business operations. Drawing on 37 in-depth interviews with sellers, buyers, and stakeholders, this paper examines how people in informal e-markets perceive and interact with the algorithm as a "team member" that performs sales,…

Advocacy for Physics and for Physicists: Results of an Informal Survey of American Physical Society Members in 2025
In the wake of a rash of executive orders and administrative actions aimed at shaping the scale, scope, and focus of the scientific enterprise in the United States during the second Trump Presidency, we have undertaken a survey of members of the American Physical Society, the country's pre-eminent physics professional society to investigate their needs, interests, and priorities, and how their interests may differ from organizational leadership's priorities. This report provides detail on the c…

A Model of Ride Dispatch in Informal Market under Rival Entry
I develop a continuous-time model in which an incumbent batch-service provider faces stochastic passenger arrivals and must decide when to dispatch under the threat of customer defection to a faster entrant. The incumbent's problem is formalized as a trade-off between departure frequency and load maximization, with the option to accept mid-route pickups. I characterize the equilibrium dispatch strategy and show that increased competitive pressure strictly reduces the feasible departure threshol…

Hitchhiking Rides Dataset: Two decades of crowd-sourced records on stochastic traveling
Hitchhiking, a spontaneous and decentralized mode of travel, has long eluded systematic study due to its informal nature. This paper presents and analyzes the largest known structured dataset of hitchhiking rides, comprising over 63,000 entries collected over nearly two decades through platforms associated with hitchwiki.org and lately on hitchmap.com. By leveraging crowd-sourced contributions, the dataset captures key spatiotemporal and strategic aspects of hitchhiking. This work documents the…

Towards Provable (In)Secure Model Weight Release Schemes
Recent secure weight release schemes claim to enable open-source model distribution while protecting model ownership and preventing misuse. However, these approaches lack rigorous security foundations and provide only informal security guarantees. Inspired by established works in cryptography, we formalize the security of weight release schemes by introducing several concrete security definitions. We then demonstrate our definition's utility through a case study of TaylorMLP, a prominent secure…

Conversational AI as a Catalyst for Informal Learning: An Empirical Large-Scale Study on LLM Use in Everyday Learning
Large language models have not only captivated the public imagination but have also sparked a profound rethinking of how we learn. In the third year following the breakthrough launch of ChatGPT, everyday informal learning has been transformed as diverse user groups explore these novel tools. Who is embracing LLMs for self-directed learning, and who remains hesitant? What are their reasons for adoption or avoidance? What learning patterns emerge with this novel technological landscape?

Deep Retrieval at CheckThat! 2025: Identifying Scientific Papers from Implicit Social Media Mentions via Hybrid Retrieval and Re-Ranking
We present the methodology and results of the Deep Retrieval team for subtask 4b of the CLEF CheckThat! 2025 competition, which focuses on retrieving relevant scientific literature for given social media posts. To address this task, we propose a hybrid retrieval pipeline that combines lexical precision, semantic generalization, and deep contextual re-ranking, enabling robust retrieval that bridges the informal-to-formal language gap. Specifically, we combine BM25-based keyword matching with a F…

Certified algorithms for numerical semigroups in Rocq
A numerical semigroup is a co-finite submonoid of the monoid of non-negative integers under addition. Many properties of numerical semigroups rely on some fundamental invariants, such as, among others, the set of gaps (and its cardinality), the Apéry set or the Frobenius number. Algorithms for calculating invariants are currently based on computational tools, such as GAP, which lack proofs (either formal or informal) of their correctness. In this paper we introduce a Rocq formalization of nume…

Impact of Outreach on Physics Student Development: Qualitative Results from a National Survey
The role of student experiences in physics beyond the classroom which support their development has been the subject of exciting research in recent years. Results, typically from small studies at single institutions, have illustrated that facilitating informal physics experiences for non-scientists can enhance student disciplinary identity, learning, sense of belonging, and more. However, it is essential to examine whether these impacts are the sole provenance of institutions with well-develope…

Designing for Community Care: Reimagining Support for Equity & Well-being in Academia
Academic well-being is deeply influenced by peer-support networks, yet they remain informal, inequitable, and unsustainable, often relying on personal connections and social capital rather than structured, inclusive systems. Additionally, institutional well-being responses frequently focus on student populations, neglecting the emotional labour of faculty and staff, reinforcing an exclusionary academic culture. Drawing on HCI methodologies, participatory design, and care ethics, this workshop w…

Compositional Control-Driven Boolean Circuits
Boolean circuits abstract away from physical details to focus on the logical structure and computational behaviour of digital components. Despite they have been studied for many decades, compositionality has been widely ignored or examined in an informal manner, which is a property for combining circuits without delving into their internal structure, while supporting modularity and formal reasoning. In this paper, we address this longstanding theoretical gap by proposing colimit-based operators…

Global Microprocessor Correctness in the Presence of Transient Execution
Correctness for microprocessors is generally understood to be conformance with the associated instruction set architecture (ISA). This is the basis for one of the most important abstractions in computer science, allowing hardware designers to develop highly-optimized processors that are functionally "equivalent" to an ideal processor that executes instructions atomically. This specification is almost always informal, e.g., commercial microprocessors generally do not come with conformance specif…

Eccentricity, extendable choice and descending distributive forcing
We introduce the forcing property of descending distributivity. A forcing $\mathbb{P}$ is $κ$-descending distributive if for all decreasing sequences $(D_α)_{α<κ}$ of open dense sets, $\bigcap_αD_α$ is open dense. This generalises the informal idea that $\mathbb{P}$ doesn't affect much on the scale of $κ$, such as if $\mathbb{P}$ is $κ$-distributive or if $κ> \lvert \mathbb{P} \rvert$. For example, a $κ$-descending distributive forcing will not change the cofinality of $κ$ or introdu…
