Production of Σ(1385)± and Ξ(1530)0 in proton–proton collisions at √s = 7 TeV
(Springer, 2015-01-10)
The production of the strange and double-strange baryon resonances ((1385)±, Ξ(1530)0) has been measured at mid-rapidity (|y|< 0.5) in proton–proton collisions at √s = 7 TeV with the ... |
In Babai nearest plane algorithm(solve approximate version of CVP), given the basis as input first step is to find the reduced basis(using LLL reduction algorithm). Why the reduced basis is used for further steps?

From the last two positions, we see that $4\cdot(10R+E)\equiv 10E+R \bmod{100}$. This is equivalent to $39R\equiv6E\bmod{100}$, and further to $13R\equiv2E\bmod{100}$.Hence $R$ has to be even. Checking $R=0,2,4,6,8$, we see that only $R=8$ works.
We conclude that $R=8$ and that $E=2$, and that the carry over from the s... |

Can AI generate music that we humans find beautiful, perhaps even moving? Let’s find out!

Heat is the total kinetic energy of all atoms of the system. When work is done on the system it means that a part of system kinetic energy is used to do the work, and this work makes the surrounding warmer. So "$\Delta U$" of the system is equal to "$Q$". And now, why we use the work of the system in: $\Delta U = Q + W... |

Theorem Proof
By definition, $m$ is odd.
$m \equiv 1 \pmod 4$. $m$ is of the form $\displaystyle \sum_{k \mathop = 0}^{r - 1} 10^k$ where $r$ is the number of digits.
Thus for $r \ge 2$:

I have a bivariate normal distribution$$(X, Y)\sim N(\mu_{x}, \mu_{y}, \sigma_{x}^2, \sigma_{y}^2, \rho)$$ My question is : when $X > k$ ($k$ is a constant),how to get the distribution of $Y$? Can anyone tell me how to solve it? For exaple, let $$(X, Y) \sim N(0, 0, 1, 1, 0.7)$$ when $X > 1$, the distribution of $Y$?

Warning: my background is mostly in probability and analysis, and not in logic.
When reading or writing a complex proposition, with long chains of "for all... there exists... for all...", I tend to understand the structure of the sentence of quantifiers as a a way to describe how some parameters depend on other paramet... |
$L_1$ convergence (which means $E(|X_n-X|)\to 0) $and almost sure convergence are incomparable conditions where neither implies the other. Yours must be an example where almost sure convergence doesn't imply $L_1$ convergence. There are simpler examples, like
$$ X_n = \left\{\begin{array}{ll}0&\mbox{with probability $1... |

In this assignment you will get your hands dirty with theano, which is a framework that has been the basis of a lot of work in deep-learning. Writing code in theano is very different than what we are accustomed to. In class you had a taste of it, where w... |

Reciprocal of Positive Real Number is Positive Theorem
Let $a \in \R$ such that $a > 0$.
Then $a^{-1} = \dfrac 1 a > 0$.
It follows directly that $a < 0 \implies a^{-1} < 0$. Proof
Aiming for a contradiction, suppose $a > 0$ but $a^{-1} \le 0$.
\(\displaystyle a^{-1}\) \(\le\) \(\displaystyle 0\) \(\displaystyle \leads... |

What Murray-von Neumann did was to show that there is an infinite-dimensional generalization of the following fact.
If $\mathcal H$ is finite-dimensional and $\mathcal M\subset\mathcal B(\mathcal H)$ is a von Neumann algebra, it is a basic exercise that we can see $\mathcal B(\mathcal H)$ as $M_n(\mathbb C)$ for $n=\di... |
Let $\varphi: A \rightarrow B$ be an integral ring homomorphism. Show that the induced morphism $\tilde{\varphi}:\mathrm{Spec}B \rightarrow \mathrm{Spec}A$ is closed.
My idea:
Let $I$ be an ideal of $B$. We have $\tilde{\varphi}(V(I)) \subset V(\varphi^{-1}(I))$ since $\tilde{\varphi}(\mathfrak{q}) = \varphi^{-1}(\math... |
I have recently been reading about the interpretation of the Aharonov-Bohm effect via Feynman's path integral (see viXra:1403.0950). I do not know whether I am missing something, but I do not understand why when evaluating the action they have to take into account the potential even if the electron does not "feel" the ... |
Today represents the half-way point of the class, both in terms of the calendar and in terms of the quantity of material that we are going to cover. On the one hand, it seems like the course is going by incredibly quickly (and it is). On the other hand, that first week of instruction feels so very long ago. So today, w... |
