sp_primary_school: Primary school dynamic contacts (2009)
Two temporal networks of contacts among students and teachers at a primary school in Lyon, France, on consecutive days of in October 2009. Each network accumulates all contacts over the course of a single day; contacts were sampled at 20-second intervals.
This network has 242 nodes and 125773 edges.

What is modern monetary theory? An economist explains how it could help Canada
Few words spark more anxiety in public debate than “national debt” and “government deficit.” National debt is the total amount of money the government owes, accumulated over years of running deficits. Government deficit is when the government spends more money than it collects in taxes and other revenues.

What is modern monetary theory? An economist explains how it could help Canada
A heterodox school of economic thought known as modern monetary theory has significant implications for how Canadians understand public debt and deficit spending.

Turbulent Snow Transport and Accumulation: New Reduced-Order Models and Diagnostics
Understanding and modeling snow particle dynamics in the atmosphere remains a significant challenge for atmospheric scientists, hydrologists, and glaciologists. Temporally and spatially varying rates of snow transport, deposition, and erosion are driven by atmospheric turbulence and further complicated by inertial particle dynamics. Even with perfectly resolved wind fields, accurately predicting the fate of mobile snow particles in wind relies on semi-empirical assumptions embedded in diffeo-in…

Modular data assimilation for flow prediction
This report develops several modular, 2-step realizations (inspired by Kalman filter algorithms) of nudging-based data assimilation \begin{equation*} \begin{array}{cc} Step{\text { }}1 & \begin{array}{c} \frac{\widetilde {v}^{n+1}-v^{n}}{k}+v^{n}\cdot \nabla \widetilde {v}% ^{n+1}-ν\triangle \widetilde {v}^{n+1}+\nabla q^{n+1}=f(x){\text { }% } \\ \nabla \cdot \widetilde {v}^{n+1}=0% \end{array} \\ Step{\text { }}2 & \frac{v^{n+1}-\widetilde {v}^{n+1}}{k}-χI_{H}(u(t^{n+1})-v^{n+1})=0.% \end{a…

Finite-size security analysis for quantum protocols: A Python framework using the Entropy Accumulation Theorem with graphical interface
We present a comprehensive software framework for the finite-size security analysis of quantum random number generation (QRNG) and quantum key distribution (QKD) protocols, based on the Entropy Accumulation Theorem (EAT). Our framework includes both a Python API and an intuitive graphical user interface (GUI), designed to support protocol designers and experimentalists in certifying randomness and key rates under realistic, finite-resource conditions. At its core, the framework automates the co…

Our results confirm persistent gender disparities:
women are more frequently acknowledged than credited as co-authors, especially in roles involving investigation and analysis

Dissecting the gender divide: Authorship and acknowledgment in scientific publications
The issue of gender bias in scientific publications has been the subject of ongoing debate. One aspect of this debate concerns whether women receive equal credit for their contributions compared to men. Conventional wisdom suggests that women are more likely to be acknowledged than listed as co-authors, a role that carries greater prestige. Here, we analyze data from hundreds of thousands of scientists across nine disciplines and a broad range of publications. Our results confirm persistent gen…

Tipping Point Sensitivity Analysis for Missing Data in Time-to-Event Endpoints: Model-Based and Model-Free Approaches

Tipping Point Sensitivity Analysis for Missing Data in Time-to-Event Endpoints: Model-Based and Model-Free Approaches
Missing data frequently occurs in clinical trials with time-to-event endpoints, often due to administrative censoring. Other reasons, such as loss-to-follow up and patient withdrawal of consent, can violate the censoring-at-random assumption hence lead to biased estimates of the treatment effect under treatment policy estimand. Numerous methods have been proposed to conduct sensitivity analyses in these situations, one of which is the tipping point analysis. It aims to evaluate the robustness o…

Structural Optimal Jacobian Accumulation and Minimum Edge Count are NP-Complete Under Vertex Elimination

Structural Optimal Jacobian Accumulation and Minimum Edge Count are NP-Complete Under Vertex Elimination
We study graph-theoretic formulations of two fundamental problems in algorithmic differentiation. The first (Structural Optimal Jacobian Accumulation) is that of computing a Jacobian while minimizing multiplications. The second (Minimum Edge Count) is to find a minimum-size computational graph. For both problems, we consider the vertex elimination operation. Our main contribution is to show that both problems are NP-complete, thus resolving longstanding open questions. In contrast to prior work…

I believe this is the first coverage to acknowledge that Lurie’s budget seems to treat a “temporary” new jail as permanent
“representatives from the People’s Budget Coalition lined the second and third floor balconies of City Hall’s rotunda. They held yellow posters reading ‘No new jail! No cuts!’ referring to the continued funding for the jail annex in San Bruno.”

Hundreds protest S.F. budget cuts, packing City Hall chambers
Protesters unfurled banners in the San Francisco City Hall rotunda reading "Stop cuts" that were quickly taken down by sheriff's deputies.
