Most of existing manifold learning methods rely on Mean Squared Error (MSE) or $\ell_2$ norm. However, for the problem of image quality assessment, these are not promising measure. In this paper, we introduce the concept of an image structure manifol...
Sunspots, as seen in white light or continuum images, are associated with regions of high magnetic activity on the Sun, visible on magnetogram images. Their complexity is correlated with explosive solar activity and so classifying these active region...
Recent deep learning models outperform standard lossy image compression codecs. However, applying these models on a patch-by-patch basis requires that each image patch be encoded and decoded independently. The influence from adjacent patches is there...
Known as the Michanikos, Hero of Alexandria is considered the inventor of the world's first steam engine and of many other sophisticated devices. Here we discuss three of them as described in his book "Pneumatica". These machines, working with water,...
We have obtained 18 new high-resolution spectropolarimetric observations of the B2Vp star sigma Ori E with both the Narval and ESPaDOnS spectropolarimeters. The aim of these observations is to test, with modern data, the assumptions of the Rigidly Ro...
Game companies avoid sharing their game data with external researchers. Only a few research groups have been granted limited access to game data so far. The reluctance of these companies to make data publicly available limits the wide use and develop...
Nov 21, 2025 · These five early- and mid-career researchers are shaking up what we know about the Arctic, black holes and beyond.
We report results based on mid-infrared photometry of 5 active main belt objects (AMBOs) detected by the Wide-field Infrared Survey Explorer (WISE) spacecraft. Four of these bodies, P/2010 R2 (La Sagra), 133P/Elst-Pizarro, (596) Scheila, and 176P/LIN...
Use these codes wisely it will grant you a lot of power (⭐ 0)
The Wide-field Infrared Survey Explorer (WISE) observed 52 Centaurs and Scattered Disk Objects in the thermal infrared, including the 15 discoveries that were new. We present analyses of these observations to estimate sizes and mean optical albedos....

I was on a friendly server streak until this round, where a raider was killing half the lobby, so I tried to get rid of him, before he gets rid of me, as I had a very expensive loadout, to push a big ...
We report measurements of the charge-separated $W^{+(-)} \to e^{+(-)} + ν_e(\barν_e)$ and $Z/γ^* \to e^+e^-$ production cross sections at mid-rapidity in proton-proton collisions at $\sqrt{s}$ = 500 GeV. These results are based on 13.2 pb$^{-1}$ o...
Yes, but these rules can be violated: 1. во Ð´Ð²Ð¾Ñ has no unstable (fugitive) vowel, в дни doesn't have to have "о" after the preposition 2. в воÑкÑеÑенÑе doesn't get "o" after the preposition, 3. just a bunch â¦
Both fun and educational, these word search games on Science cover chemistry, biology and physics. All puzzles can be played online or printed to use in a classroom.
One of the first things to do while planning a trip is to book a good place to stay. Booking a hotel online can be an overwhelming task with thousands of hotels to choose from, for every destination. Motivated by the importance of these situations, w...
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW241110. The sources of these two signals are characterized by rapid an...
Oct 16, 2025 · But “Grey’s” is a nighttime drama, not a documentary, so she’s learned what battles to fight. Her greatest source of pride on the job, she says, is teaching actors how to be doctors.
Empirical stellar libraries are extensively used to extract stellar kinematics in galaxies and to build stellar population models. An accurate knowledge of the spectral resolution of these libraries is critical to avoid propagation errors and uncerta...
