Spotted this tiny praying mantis peeping in our window. I think just under 2 centimeters long. I tried to get my index finger in for scale.

Coinductive well-foundedness
We introduce a coinductive version of the well-foundedness of N that is used in our proof within minimal logic of the constructive counterpart CLNP to the standard least number principle LNP. According to CLNP, an inhabited complemented subset of N has a least element if and only if it is downset located. The use of complemented subsets of N in the formulation of CLNP, instead of subsets of N, allows a positive approach to the subject that avoids negation. Generalising the coinductive well-foun…

Defect-Mediated Pairing and Dissociation of Strongly Correlated Electrons in Low Dimensional Lattices: The Quantum Taxi Effect
We study the quantum dynamics of a strongly correlated electron pair in a one-dimensional lattice, focusing on the occurrence of local dissociation/pairing mechanisms induced by a site energy defect. To this end, we simulate the time evolution of two interacting electrons on a finite-size chain governed by an extended Hubbard Hamiltonian including on-site Coulomb repulsion $ U $ and nearest-neighbor interaction $V$, along with single-electron hopping $J$. By introducing a local site energy defe…

#gsa has told #nasa to vacate it’s only office in #nyc
#columbia and nasa with about 2/3 of the 120 people in the building being researchers employed by Columbia. This lab could not exist at all outside of nyc.
This lab, along with #gfdl in Princeton NJ were the first to come up with how sensitive the #climate is to inputs of CO2 in the 1979 Charney report.
We still make estimates of future climate change today.

ClinBench-HPB: A Clinical Benchmark for Evaluating LLMs in Hepato-Pancreato-Biliary Diseases
Hepato-pancreato-biliary (HPB) disorders represent a global public health challenge due to their high morbidity and mortality. Although large language models (LLMs) have shown promising performance in general medical question-answering tasks, the current evaluation benchmarks are mostly derived from standardized examinations or manually designed questions, lacking HPB coverage and clinical cases. To address these issues, we systematically eatablish an HPB disease evaluation benchmark comprising…

Fully characterized linear magnetoelectric response of 2D monolayers from high-throughput first-principles calculations
We screen 4784 stable monolayers from the Computational 2D Materials Database (C2DB) and identify 57 ferromagnetic (FM) and 67 antiferromagnetic (AFM) that should exhibit linear magnetoelectric (ME) effects. Using density functional theory, we compute contributions from the spin and orbital angular momentum as well as lattice-mediated and clamped-ion analogs to fully characterize the linear ME tensor in the static limit. We observe a general trend that AFM ordering gives rise to a larger ME res…

" The gutting of NOAA was outlined earlier this month in a leaked memo from the Office of Management and Budget that detailed steep reductions at the Department of Commerce, which houses the science agency. ... NOAA’s overall funding would be slashed by 27%…
most significant target is the office of Oceanic and Atmospheric Research ⎯ a nerve center of global climate science, data collection and modeling, including the Geophysical Fluid Dynamics Laboratory ⎯ which would be cut by 74%. “At this funding level, OAR is eliminated as a line office,” the memo stated.”
