We analyze an upper bound on the curvature of a Riemannian manifold, using "root-Ricci" curvature, which is in between a sectional curvature bound and a Ricci curvature bound. (A special case of root-Ricci curvature was previously discovered by Osser...
May 13, 2025 · Serendipity has led to many scientific breakthroughs. For instance, Alexander Fleming discovered penicillin while doing research on influenza. But unlike scientists, business leaders and …
A neutron is a subatomic particle, symbol n or n0 , that has no electric charge, and a mass slightly greater than that of a proton. The neutron was discovered

The idea of the global gravitational effect as the source of cosmological redshift was considered by de Sitter (1916, 1917), Eddington (1923), Tolman (1929) and Bondi (1947). Also Hubble (1929) called the discovered distance-redshift relation as "De...
In the early 1880s, Henri Poincaré discovered a new equilibrium figure for uniformly-rotating fluid masses -- the pear, or piriform figure -- and speculated that in certain circumstances the pear splits into two unequal parts, and provides thereby a...
Here, we present the comparative study of magnetotransport properties of recently discovered Ta2PdTe6 and Nb2PdS5 superconductors. The XRD and magnetotransport measurements are performed on these samples to investigate structure and superconducting p...
Due to the low gamma-ray fluxes from pulsars above 50 GeV and the small collecting area of space-based telescopes, the gamma-ray emission discovered by the Fermi-LAT in $\sim$150 pulsars is largely unexplored at these energies. In this regime, the un...
Recently I discovered about Quarterly Theory by Daye and his concept about SSMT, and the correlation between the gaps in ES / NQ and more complex details which sound foreign to me. I wonder if it's ne...
Small finds is an archaeological term for artifacts discovered on excavations that are considered distinct from the common finds for that type site or
We present three new clusters discovered in the halo of M31 which, although having globular-like colours and luminosities,have an unusually large half-light radii, ~30 pc. They lie at projected galactocentric distances of approx. 15 to 35 kpc. Thes...
The Pluto-Charon system provides a broad variety of constraints on planetary formation, composition, chemistry, and evolution. Pluto was the first body to be discovered in what is now known as the Kuiper belt, its orbit ultimately becoming a major cl...

Silicon, a ubiquitous material in modern computing, is an emerging platform for realizing a source of indistinguishable single-photons on demand. The integration of recently discovered single-photon emitters in silicon into photonic structures, is ad...
Results of photometric and spectroscopic investigations of the recently discovered disc cataclysmic variable star 1RXS J180834.7+101041 are presented. Emission spectra of the system show broad double peaked hydrogen and helium emission lines. Doppler...
Results of photometric and spectroscopic investigations of the recently discovered eclipsing cataclysmic variable star HBHA 4705-03 are presented. The emission spectra of the system show broad hydrogen and helium emission lines. The bright spots with...
We present a detailed study of the gas and galaxy properties of the cluster PSZ2 G282.28+49.94 detected in the Planck all-sky survey. The intracluster medium (ICM) of this object at z=0.56 exhibits a cometary-like shape. Combining Chandra and TNG obs...
Nov 27, 1995 · Margaret Fetterolf - Baltimore County DNA testing has identified Margaret Fetterolf, 16, as the body that was discovered in the 5600 block of Dogwood Road, 21207 in Precinct 2 Woodlawn …
The ability to control and manipulate time-reversal ($T$) symmetry-breaking phases with near-zero net magnetization is a sought-after goal in spintronic devices. The recently discovered hexagonal altermagnet manganese telluride ($α$-MnTe) is a prime...
