Is Earendel a Star Cluster? Metal Poor Globular Cluster Progenitors at z~6: #Earendel within the Sunrise was previously identified as a candidate star or binary due to size constraints placed by the lensing magnification, however recent works have suggested this constraint may be relaxed to even the size of star clusters. Here, we explore the hypothesis that Earendel may actually be a star cluster, and simultaneously evaluate other star clusters within the host galaxy."

Israel outlines plans to pack Gaza's population into a closed border zone
Israeli media reports that the country’s defense minister has outlined plans to pack hundreds of thousands of Palestinians into a closed zone of the Gaza Strip along the border with Egypt. It appears to be the latest version of plans by the Israeli government to maintain lasting control over the territory and relocate much of its population of some 2 million. Critics say that would amount to forcible displacement in violation of international law because Israel’s offensive and blockade have…

Spectroscopic Characterization of redMaPPer Galaxy Clusters with DESI
Optical galaxy cluster identification algorithms such as redMaPPer promise to enable an array of astrophysical and cosmological studies, but suffer from biases whereby galaxies in front of and behind a galaxy cluster are mistakenly associated with the primary cluster halo. These projection effects caused by irreducible photometric uncertainty must be quantified to facilitate the use of optical cluster catalogues. We present measurements of galaxy cluster projection effects and velocity dispersi…

Optimizing Scalable Multi-Cluster Architectures for Next-Generation Wireless Sensing and Communication
Next-generation wireless technologies (for immersive-massive communication, joint communication and sensing) demand highly parallel architectures for massive data processing. A common architectural template scales up by grouping tens to hundreds of cores into shared-memory clusters, which are then scaled out as multi-cluster manycore systems. This hierarchical design, used in GPUs and accelerators, requires a balancing act between fewer large clusters and more smaller clusters, affecting design…

Diverse mean-field dynamics of clustered, inhibition-stabilized Hawkes networks via combinatorial threshold-linear networks
Networks of interconnected neurons display diverse patterns of collective activity. Relating this collective activity to the network's connectivity structure is a key goal of computational neuroscience. We approach this question for clustered networks, which can form via biologically realistic learning rules and allow for the re-activation of learned patterns. Previous studies of clustered networks have focused on metastabilty between fixed points, leaving open the question of whether clustered…

Efficient Computation of Closed Substrings
A closed string $u$ is either of length one or contains a border that occurs only as a prefix and as a suffix in $u$ and nowhere else within $u$. In this paper, we present a fast and practical $O(n\log n)$ time algorithm to compute all $Θ(n^2)$ closed substrings by introducing a compact representation for all closed substrings of a string $ w[1..n]$, using only $O(n \log n)$ space. We also present a simple and space-efficient solution to compute all maximal closed substrings (MCSs) using the s…
