An element $a$ of a ring $R$ is called perfectly clean if there exists an idempotent $e\in comm^2(a)$ such that $a-e\in U(R)$. A ring $R$ is perfectly clean in case every element in $R$ is perfectly clean. In this paper, we investigate conditions on...
We define two types of rings, namely the so-called CSNC and NCUC that are those rings whose clean elements are strongly nil-clean, respectively, whose nil-clean elements are uniquely clean. Our results obtained in this paper somewhat expand these obt...
You've heard the music. Now see the place that Elvis Presley called home. See his mansion, private gardens, aircraft, and more for an unforgettable experience.
In the standard Big-Bang nucleosynthesis (BBN) model, the primordial $^7$Li abundance is overestimated by about a factor of 2--3 comparing to the astronomical observations, so called the pending cosmological lithium problem. The $^7$Be($n$,$α$)$^4$H...
There’s a tteokbokki place in Dongtan 2 — it’s called “옥이네 떡볶이“ and it’s really delicious. It’s so popular that there’s often a long line on weekends! Who wants to go with ...
2012. Sometimes called the lex Flaminia agraria, eg, von Ungern-Sternberg, Jrgen (2005). "The end of the Conflict of the Orders". In Raaflaub, Kurt A (ed
We find the optimal investment strategy to minimize the expected time that an individual's wealth stays below zero, the so-called {\it occupation time}. The individual consumes at a constant rate and invests in a Black-Scholes financial market cons...
We determine the optimal investment strategy in a Black-Scholes financial market to minimize the so-called {\it probability of drawdown}, namely, the probability that the value of an investment portfolio reaches some fixed proportion of its maximum v...
Pruning refers to the elimination of trivial weights from neural networks. The sub-networks within an overparameterized model produced after pruning are often called Lottery tickets. This research aims to generate winning lottery tickets from a set o...

Practice here, then obliterate your friends! Drag and Drop. For a double jump, drag and drop twice. Blue goes first. Also called Draughts. Note about multiple jumps: it is a basic rule in …
For any regular Lie algebroid $A$, the kernel $K$ and the image $F$ of its anchor map $ρ_A$, together with $A$ itself fit into a short exact sequence, called Atiyah sequence, of Lie algebroids. We prove that Atiyah and Todd classes of dg manifolds a...
We have created a platform for online deliberation called Deme (which rhymes with 'team'). Deme is designed to allow groups of people to engage in collaborative drafting, focused discussion, and decision making using the Internet. The Deme project ha...
I had a traumatic brain injury as a child. It left me with some physical impairments as well as slurred speech. My sister has always thought I used my condition to get extra attention from our parents...
**The Haunting Story of OB-1303** The plane in question was a three-engine Boeing 727 passenger jet registered as OB-1303, which was owned by an airline called Faucett Perú. Faucett mostly operated ...

We discuss a method to improve the exact F-measure maximization algorithm called GFM, proposed in (Dembczynski et al. 2011) for multi-label classification, assuming the label set can be can partitioned into conditionally independent subsets given the...
Sep 11, 2020 · Hello, I struggle to decide which faction to play as when beginning a new game. Fortunately I discovered this tool online called Wheel of Names. Now I can...
We present an extension of Vapnik's classical empirical risk minimizer (ERM) where the empirical risk is replaced by a median-of-means (MOM) estimator, the new estimators are called MOM minimizers. While ERM is sensitive to corruption of the dataset...
