Differentiable Optimization of Linear Differential Microphone Arrays: A Joint Geometry and Filter Design Framework
arXiv:2412.05123v2 Announce Type: replace Abstract: This paper presents a differentiable optimization framework for the design of constrained Linear Differential Microphone Arrays (LDMAs). The proposed method leverages a non-uniform delay-and-sum beamformer as a light-weight base system model, proving its ability to achieve the optimal beampattern of LDMAs by jointly optimizing microphone positions and filter weights. The formulation enables the optimized design of a filter with a...
Whole-genome duplication shaped cell-type evolution in the vertebrate brain
Abstract The complex brains of vertebrates have more cell types than those of their closest relatives. Whole-genome duplications (WGDs) occurred during early vertebrate evolution1, but it is unclear whether the duplicated genes (ohnologues) facilitated cell-type evolution. Here using brain single-cell transcriptomes from five chordates—human2, mouse3, lizard4, lamprey5 and amphioxus—we report that many cell-type families with conserved core transcription factors in vertebrates do not show...
22 World Cup items, 22 stories
FIFA won't reveal how, but after every game at the 2026 World Cup this summer, it will be collecting items that will one day document the tournament. It already has the net from the 2018 World Cup final, for example, as well as the tracksuit that Pelé wore at his first World Cup in 1958. The items live in FIFA's various museums, ranging from Vancouver and Miami to Zurich and Hong Kong.
The divine (actually!) force behind Wemby and the ...
AT 6 P.M. THEY gathered inside an elementary school gymnasium, located on San Antonio's westside, to watch Game 7 of the Western Conference finals. Kahlig Auto Group, a local car dealer, had sponsored the watch party with a meal from a local taqueria to feed the nearly 200 attendees, who feasted on enchiladas, rice and beans, chips, guacamole, salsa and four colorful jugs of aguas frescas. Rows of folding chairs faced a projector screen set up on a stage that was lined with black and silver...
A prognostic human brain network for diffuse midline glioma
Abstract Diffuse midline gliomas (DMGs) are near-universally lethal tumours of the childhood central nervous system1,2. In animal models, DMGs form brain-wide integrated networks through neuron-to-glioma synapses3,4,5,6 and glioma-to-glioma gap junctional coupling3. This extensive connectivity robustly promotes the growth and invasion of DMG3,4,5,6,7,8,9 and other glial malignancies10,11,12 through paracrine mechanisms and direct neuron-to-glioma synapses.
