Catalytic swimmers have attracted much attention as alternatives to biological systems for examining collective microscopic dynamics and the response to physico-chemical signals. Yet, understanding and predicting even the most fundamental characteris...
Microscopic active droplets are able to swim autonomously in viscous flows: this puzzling feature stems from solute exchanges with the surrounding fluid via surface reactions or their spontaneous solubilisation, and the interfacial flows resulting fr...
Self-sustained oscillations resulting from fluid-solid instabilities, such as the flutter of a flexible flag in axial flow, can be used to harvest energy if one is able to convert the solid energy into electricity. Here, this is achieved using piezoe...
Simultaneous localisation and mapping (SLAM) is the problem of autonomous robots to construct or update a map of an undetermined unstructured environment while simultaneously estimate the pose in it. The current trend towards self-driving vehicles ha...
1995 – Researchers at Fermilab in Illinois announced the discovery of the top quark, the most massive of all observed elementary particles. 2014 – The Oscar selfie, considered to be one of the most …
5 days ago · The transition from non-life to life was very likely aided by an asteroid hitting Earth, prebiotic chemistry, molecular self-replication, and the emergence of membranes.
Einstein-Dirac equations for two spinor fields are considered. It is shown that in this case one can obtain self-consistent equations set for these gravitating spinors. The key idea to obtain Einstein-Dirac equations is to use special ansätze for sp...
We present UBVI photometry for the old open cluster Collinder 261. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of th...
200, Heart's self-titled album reached number one in 1985 and was certified quintuple platinum by the Recording Industry Association of America (RIAA)
Hi everyone, Welcome to the first discussion of **The Heart of a Woman**, which is the fourth book in Maya Angelou's autobiography series! The individual volumes are fairly self-contained, so you do ...

Tackle procrastination by using self-destructing tabs and boost your productivity. (⭐ 73)
Many people hold this truth to be self-evident, that there should be more female students in science and engineering. Typical arguments include possible benefits to women, possible benefits to the economy, and the unfairness of the current female u...
Hey all, long time listener first time caller. 33m, baldness in the family. I've been holding on to what I have left, but it's reaching a point where I'm so, so self conscious when I go out in public....
Stress is an inevitable part of day-to-day life yet many find themselves unable to manage it themselves, particularly when professional or peer support are not always readily available. As self-care becomes increasingly vital for mental well-being, t...
"Kiwi" (/ˈkiːwi/ KEE-wee) is a common self-reference used by New Zealanders, though it is also used internationally. The label is generally viewed as a
In this paper, we collect and study Twitter communications to understand the societal impact of COVID-19 in the United States during the early days of the pandemic. With infections soaring rapidly, users took to Twitter asking people to self isolate...
We show that a composition operator induced by an analytic self-map of the unit disc in the complex plane is weakly compact on the space BMOA precisely when the operator is compact on BMOA. As a crucial step we simplify the compactness criterion du...
Self-gravitating horizonless ultra-compact objects that possess light rings have attracted the attention of physicists and mathematicians in recent years. In the present compact paper we raise the following physically interesting question: Is there a...
