Bitwise operations in Java give different value with similar code?
Short question. I am quite new to doing bit/bytewise operations in Java, but I noticed something strange.

Behaviour of Laplace transform as $s \to \infty$
I have shown that if $f$ is a continuous function with scaling symmetry given by $f(mt)=m^kf(t)$ for any $m>0$, than $(\mathcal{Lf})(s) = m^{-k-1}(\mathcal{Lf})(\frac{s}{m})$.
For this $f$, what can be said about $\int_{0}^{\infty}f(t)\,dt$ and what is the behaviour of $... | common-pile/stackexchange_filtered |

How to set the default style to a React Component

If a relation is euclidean, is it necessarily asymmetric?
$R$ is relation on set $A$, that is $R\subseteq A \times A $. $R$ is euclidean if $(\forall x,y,z\in A)(xRy\land xRz \Rightarrow yRz)$. $R$ is asymmetric if $(\forall x,y\in A)(xRy\Rightarrow \lnot(yRx)).$
