I wouldn't over-claim re China's emissions reduction.
The reduction is only 1% and still likely to change to an increase.
Moreover, "Many wind and solar power projects have been halted across multiple Chinese regions "after a shift to market pricing. …

Chinese Wind, Solar Projects Shut Amid Shift to Market‐Based Pricing

Rural Republicans used to back NPR. Then MAGA changed everything.
Polarized views of public broadcasting,
along with a splintered and increasingly online media environment,
pose a problem for NPR, PBS and their audiences,
who will need some Republicans to break ranks to prevent the cuts that Trump is demanding
as part of a larger package of budget reductions that the House will consider as soon as Tuesday.

Sharper Convergence Rates for Nonconvex Optimisation via Reduction Mappings
Many high-dimensional optimisation problems exhibit rich geometric structures in their set of minimisers, often forming smooth manifolds due to over-parametrisation or symmetries. When this structure is known, at least locally, it can be exploited through reduction mappings that reparametrise part of the parameter space to lie on the solution manifold. These reductions naturally arise from inner optimisation problems and effectively remove redundant directions, yielding a lower-dimensional obje…

Telescoping Algorithms for $Σ^*$-Extensions via Complete Reductions
A complete reduction on a difference field is a linear operator that enables one to decompose an element of the field as the sum of a summable part and a remainder such that the given element is summable if and only if the remainder is equal to zero. In this paper, we present a complete reduction in a tower of $Σ^*$-extensions that turns to a new efficient framework for the parameterized telescoping problem. Special instances of such $Σ^*$-extensions cover iterative sums such as the harmonic …

Towards numerical two-loop integrand reduction
We present a method for the integrand-level reduction of two-loop helicity amplitudes in both $d=4-2ε$ and $d=4$ dimensions. The amplitude is expressed in terms of a set of Feynman integrals and their coefficients that depend on the external kinematics. The analysis presented in this paper, in conjunction with the ongoing development of the computational framework $\text{HELAC-2LOOP}$, paves the road for the construction of an automated program for two-loop amplitude calculations for arbitrary…

Execution-Aware Program Reduction for WebAssembly via Record and Replay
WebAssembly (Wasm) programs may trigger bugs in their engine implementations. To aid debugging, program reduction techniques try to produce a smaller variant of the input program that still triggers the bug. However, existing execution-unaware program reduction techniques struggle with large and complex Wasm programs, because they rely on static information and apply syntactic transformations, while ignoring the valuable information offered by the input program's execution behavior. We presen…

Enabling stratified sampling in high dimensions via nonlinear dimensionality reduction
We consider the problem of propagating the uncertainty from a possibly large number of random inputs through a computationally expensive model. Stratified sampling is a well-known variance reduction strategy, but its application, thus far, has focused on models with a limited number of inputs due to the challenges of creating uniform partitions in high dimensions. To overcome these challenges, we perform stratification with respect to the uniform distribution defined over the unit interval, and…

Adaptive Reduced Order Modelling of Discrete-Time Systems with Input-Output Dead Time
While many acoustic systems are well-modelled by linear time-invariant dynamical systems, high-fidelity models often become computationally expensive due the complexity of dynamics. Reduced order modelling techniques, such as the Eigensystem Realization Algorithm (ERA), can be used to create efficient surrogate models from measurement data, particularly impulse responses. However, practical challenges remain, including the presence of input-output dead times, i.e. propagation delays, in the dat…
