Concave symplectic toric fillings
As shown by Etnyre and Honda in [EH], every contact 3-manifold admits infinitely many concave symplectic fillings that are mutually not symplectomorphic and not related by blow ups. In this note we refine this result in the toric setting by showing that every contact toric 3-manifold admits infinitely many concave symplectic toric fillings that are mutually not equivariantly symplectomorphic and not related by blow ups. The concave symplectic toric structure is constructed on certain linear and…

Managed to do a fine-scale repair for the first time in years, always a pleasure when it goes well. One of my backup earbuds split along the stem, with half the polycarbonate case and a contact plate falling out. A speck of medical skin adhesive (polyacrylate “superglue“) on each end of the case seam appears to have done the trick w/o losing the pinch functions. WOOT!

Parabolic-elliptic and indirect-direct simplifications in chemotaxis systems driven by indirect signalling
Under relevant biological situations of the signalling process on a much faster time scale compared to the species diffusion and all interactions, we study two singular limits corresponding to $\varepsilon\to 0^+$ with a fixed $τ>0$, and $(\varepsilon,τ)\to (0^+,0^+)$ arising in the following indirect signalling chemotaxis system with no-flux accross the boundary \begin{align*} \left\{\begin{array}{lllllll} \partial_t n=Δn-\nabla\cdot(n\nabla c)&\text{in }Ω\times(0,\infty),\\ \varepsilon\pa…

sp_high_school_new: High school dynamic contacts (2011-2012)
These datasets contain the temporal network of contacts between students in a high school in Marseilles, France. The first dataset gives the contacts of the students of three classes during 4 days in Dec. 2011, and the second corresponds to the contacts of the students of 5 classes during 7 days (from a Monday to the Tuesday of the following week) in Nov. 2012.
This network has 180 nodes and 45047 edges.

Optimized Kalman Filter based State Estimation and Height Control in Hopping Robots
Rotor-based hopping locomotion significantly improves efficiency and operation time as compared to purely flying systems; where most hopping robots use the liftoff states and an assumed ballistic trajectory to determine the hopping height. However, significant aerial phase force (e.g., thrust and drag) can invalidate this assumption and lead to poor estimation performance. To combat this issue, a group has implemented multiple sensors (active and passive optical, inertial, and contact) and sign…

MaXIFE: Multilingual and Cross-lingual Instruction Following Evaluation
With the rapid adoption of large language models (LLMs) in natural language processing, the ability to follow instructions has emerged as a key metric for evaluating their practical utility. However, existing evaluation methods often focus on single-language scenarios, overlooking the challenges and differences present in multilingual and cross-lingual contexts. To address this gap, we introduce MaXIFE: a comprehensive evaluation benchmark designed to assess instruction-following capabilities a…

Principal Context-aware Diffusion Guided Data Augmentation for Fault Localization
Test cases are indispensable for conducting effective fault localization (FL). However, test cases in practice are severely class imbalanced, i.e. the number of failing test cases (i.e. minority class) is much less than that of passing ones (i.e. majority class). The severe class imbalance between failing and passing test cases have hindered the FL effectiveness. To address this issue, we propose PCD-DAug: a Principal Context-aware Diffusion guided Data Augmentation approach that generate syn…
