In 2019, the hole that developed in the ozone layer over Antarctica was the smallest on record since the ozone hole was first discovered, according to scientists at NASA and the US National Ocean...
In 2006, Caltech's Paul Rothemund (BS '94)—now research professor of bioengineering, computing and mathematical sciences, and computation and neural systems—developed a method to fold a long strand of...

World’s smallest neutrino detector interactions particles
2017/9/4
In 1974, a Fermilab physicist predicted a new way for ghostly particles called neutrinos to interact with matter. More than four decades later, a UChicago-led team of physicists built the world’s smal...

AUSTIN, Texas — Researchers at the Cockrell School of Engineering at The University of Texas at Austin have built the smallest, fastest and longest-running tiny synthetic motor to date. The team’s nan...
The discovery of musky rat-kangaroo fossils has prompted experts to call for better protection of tropical rainforests after new links show the tiny marsupial cannot survive outside that environment.
Let $\chi$ be a non-principal Dirichlet character modulo a prime $p$. Let $q_1smallest prime non-residues of $\chi$. We give explicit upper bounds on $q_2$ that improve upon all ...
We construct the smallest possible self contained heat engines; one composed of only two qubits, the other of only a single qutrit. The engines are self-contained as they do not require external sourc...
Smallest eigenvalue distributions for $\beta$-Jacobi ensembles
Smallest eigenvalue distributions $\beta$-Jacobi ensembles
2010/12/10
We compute the exact and limiting smallest eigenvalue distributions for a class of -Jacobi ensembles not covered by previous studies. In the general case, these distributions are given by multivari...

Inequalities for the Smallest Zeros of Laguerre Polynomials and their $q$-analogues.
Utilizing the properties of the smallest singular value of a matrix,we propose a new, efficient and reliable algorithm for solvingnonsymmetric matrix inverse eigenvalue problems, and compare it with a...
