  • In this paper, we find an identity which connects the overpartition function and the function of Rogers--Ramanujan--Gordon type overpartitions by considering the weights and gaps. This identity can be seen as an analogue of the weighted identity of Alladi.

  • We prove that, given a partition of the point-set of $PG(3,q), q=2^n >2$, by ovoids $\{\theta_i\}^q_{i=0}$ of $PG(3,q)$ and a line $\ell$ of $PG(3,q)$, not tangent to $\theta_0$ if $\ell^\perp$ denotes the polar of $\ell$ relative to the symplectic form on $PG(3,q)$ whose isotropic lines are the tangent lines to $\theta_0$, then $\ell$ and $\ell^\perp$ are tangent to distinct ovoids $\theta_j, \theta_k$, both distinct from $\theta_0$. This uses the fact that the radical of the linear code generated by the dual duals $\ell\cup \ell^\perp$ of the hyperbolic quadrics , with $\ell$ and $\ell^\perp$ as above, is of codimension $1$

  • In this short paper, we show that the peeling property still holds for Bondi-Sachs metrics with nonzero cosmological constant under the new boundary condition with nontrivial B, X, Y obtained in [6]. This should indicate the new boundary condition is natural. Moreover, we construct some nontrivial vacuum Bondi-Sachs metrics without the Bondi news. This provides a new feature of gravitational waves for nonzero cosmological constant.

  • In communications, one frequently needs to detect a parameter vector $\hbx$ in a box from a linear model. The box-constrained rounding detector $\x^\sBR$ and Babai detector $\x^\sBB$ are often used to detect $\hbx$ due to their high probability of correct detection, which is referred to as success probability, and their high efficiency of implimentation. It is generally believed that the success probability $P^\sBR$ of $\x^\sBR$ is not larger than the success probability $P^\sBB$ of $\x^\sBB$. In this paper, we first present formulas for $P^\sBR$ and $P^\sBB$ for two different situations: $\hbx$ is deterministic and $\hbx$ is uniformly distributed over the constraint box. Then, we give a simple example to show that $P^\sBR$ may be strictly larger than $P^\sBB$ if $\hbx$ is deterministic, while we rigorously show that $P^\sBR\leq P^\sBB$ always holds if $\hbx$ is uniformly distributed over the constraint box.

  • Aguilar introduced isotropic almost complex structures $J_{\delta , \sigma}$ on the tangent bundle of a Riemannian manifold $(M,g)$. These structures with the Liouville $1$-form define a class of Riemannian metrics $g_{\delta , \sigma}$ on $TM$ which are a generalization of the Sasaki metric. In this paper, the curvature tensors will be calculated and some results on the Einstein tangent bundles and tangent bundles of constant sectional curvature will be achieved. Moreover, it will be proved that $(T\mathbb{R}^n,g_{\delta , 0})$ is an Einstein manifold if and only if $\delta$ is a constant function.

  • In this paper, we investigate complete Riemannian manifolds satisfying the lower weighted Ricci curvature bound $\mathrm{Ric}_{N} \geq K$ with $K>0$ for the negative effective dimension $N<0$. We analyze two $1$-dimensional examples of constant curvature $\mathrm{Ric}_N \equiv K$ with finite and infinite total volumes. We also discuss when the first nonzero eigenvalue of the Laplacian takes its minimum under the same condition $\mathrm{Ric}_N \ge K>0$, as a counterpart to the classical Obata rigidity theorem. Our main theorem shows that, if the minimum is attained, then the manifold splits off the real line as a warped product of hyperbolic nature.

Numbers that consist of at most a fixed number of digits are represented by vertices that are equidistant from the root vertex and the corresponding number representations do not depend on the distance from the root vertex.

  • We study Tian's $\alpha$-invariant in comparison with the $\alpha_1$-invariant for pairs $(S_d,H)$ consisting of a smooth surface $S_d$ of degree $d$ in the projective three-dimensional space and a hyperplane section $H$. A conjecture of Tian asserts that $\alpha(S_d,H)=\alpha_1(S_d,H)$. We show that this is indeed true for $d=4$ (the result is well known for $d\leqslant 3$), and we show that $\alpha(S_d,H)<\alpha_1(S_d,H)$ for $d\geqslant 8$ provided that $S_d$ is general enough. We also construct examples of $S_d$, for $d=6$ and $d=7$, for which Tian's conjecture fails. We provide a candidate counterexample for $S_5$.

  • In this paper, we give a characterization of Nikol'ski\u{\i}-Besov type classes of functions, given by integral representations of moduli of smoothness, in terms of series over the moduli of smoothness. Also, necessary and sufficient conditions in terms of monotone or lacunary Fourier coefficients for a function to belong to a such a class are given. In order to prove our results, we make use of certain recent reverse Copson- and Leindler-type inequalities.

  • Multi stage stochastic programs arise in many applications from engineering whenever a set of inventories or stocks has to be valued. Such is the case in seasonal storage valuation of a set of cascaded reservoir chains in hydro management. A popular method is Stochastic Dual Dynamic Programming (SDDP), especially when the dimensionality of the problem is large and Dynamic programming no longer an option. The usual assumption of SDDP is that uncertainty is stage-wise independent, which is highly restrictive from a practical viewpoint. When possible, the usual remedy is to increase the state-space to account for some degree of dependency. In applications this may not be possible or it may increase the state space by too much. In this paper we present an alternative based on keeping a functional dependency in the SDDP - cuts related to the conditional expectations in the dynamic programming equations. Our method is based on popular methodology in mathematical finance, where it has progres

  • We investigate monotone circuits with local oracles (K., 2016), i.e., circuits containing additional inputs $y_i = y_i(\vec{x})$ that can perform unstructured computations on the input string $\vec{x}$. Let $\mu \in [0,1]$ be the locality of the circuit, a parameter that bounds the combined strength of the oracle functions $y_i(\vec{x})$, and $U_{n,k}, V_{n,k} \subseteq \{0,1\}^m$ be the classical sets of positive and negative inputs considered for $k$-clique in the approximation method (Razborov, 1985). Our results can be informally stated as follows. 1. For an appropriate extension of depth-$2$ monotone circuits with local oracles, we show that the size of the smallest circuits separating $U_{n,3}$ (triangles) and $V_{n,3}$ (complete bipartite graphs) undergoes two phase transitions according to $\mu$. 2. For $5 \leq k(n) \leq n^{1/4}$, arbitrary depth, and $\mu \leq 1/50$, we prove that the monotone circuit size complexity of separating the sets $U_{n,k}$ and $V_{n,k}$ is $n^{\Theta

We derive a sum-DoF upperbound which depends on the average CSIT quality of each user. This upperbound is shown to be tight under total order, i.e. when the order of users with respect to their CSIT qualities is preserved over all subchannels. In this case, it is shown that separate coding over each subchannel is optimum in a sum-DoF sense.

    Kendrick Lamar’s Holy Spirit

    04-19 THE NEW YORKER 79

    At some point during 2015, Kendrick Lamar came to seem like much more than a rapper. One of his best songs, “Alright,” was adopted by the Black Lives Matter movement as an informal anthem; sing-alongs erupted at rallies and protests across the country. “Alright” somehow manages to sound carefree yet urgent, like a radio jingle perforated by drum fills. “We been hurt, been down before,” Lamar raps, preaching about the glory inherent in struggle. “We gon’ be alright.” He sounded like a prophet, capable of articulating what people in the streets desired but couldn’t put into words.

The subsidiary of Malaysian Airline System Bhd reached a deal with Aireon LLC, SITAONAIR and FlightAware LLC to enable it to monitor the flight paths of its aircraft anywhere in the world including over the polar regions and the most remote oceans, according to an emailed press release from Aireon. Aireon is launching a new satellite network with Iridium Communications Inc. that will allow it to monitor air traffic around the globe. It's projected to be completed in 2018. Most international flights are already transmitting their position with technology known as ADS-B and the signals can be tracked from the ground or space.

Currently, Ubuntu Touch, Sailfish OS/Mer, Plasma Mobile, and others use different Android source trees and methods for differently-built stacks. This leads to a lot of fragmentation among the most popular non-Android, GNU/Linux-based mobile OS projects in their use of the Android source tree, how the Android init is started, and how images are flashed to the device. Many of these projects essentially do the same job, but in a different way." The goal of Halium is to work towards a common Linux base, which can be used by all of these different projects.

Now, it's hoping to co-design super-cool memory for quantum computers. The company is working with Rambus to develop and build prototype computers with memory subsystems that can be cooled at cryogenic temperatures, typically below minus 180 degrees Celsius or minus 292 degrees Fahrenheit. Cryogenics goes hand in hand with quantum computers, which promise to be significantly faster than today's PCs and servers and may even eventually replace them. But the systems are notoriously unstable and need to be stored in refrigerators for faster and secure operation. As an example, D-Wave's 2000Q quantum computer needs to be kept significantly cooler than supercomputers so operations don't break down.

Now, they are finding signs of something unexpected at the Large Hadron Collider (LHC), the world's biggest atom smasher at CERN, the European particle physics laboratory near Geneva, Switzerland. The hints come not from the LHC's two large detectors, which have yielded no new particles since they bagged the last missing piece of the standard model, the Higgs boson, in 2012, but from a smaller detector, called LHCb, that precisely measures the decays of familiar particles. The latest signal involves deviations in the decays of particles called B mesons -- weak evidence on its own. But together with other hints, it could point to new particles lying on the high-energy horizon. "This has never happened before, to observe a set of coherent deviations that could be explained in a very economical way with one single new physics contributio

Blizzard has just released the original game -- plus the Brood War expansion -- for free for both PC and Mac. You can find it here. Up until a few weeks ago, getting the game with its expansion would've cost $10-15 bucks. The company says they've also used this opportunity to improve the game's anti-cheat system, add "improved compatibility" with Windows 7, 8.1, and 10, and fix a few long lasting bugs. So why now? The company is about to release a remastered version of the game in just a few months, its graphics/audio overhauled for modern systems. Once that version hits, the original will probably look a bit ancient by comparison -- so they might as well use it to win over a few new fans, right?

The Qualcomm Snapdragon 835 processor on board the GS8 is currently a Samsung exclusive, though it's expected to arrive in other handsets later this year. The Adreno 540 graphics engine on board the new Snapdragon chip is roughly 25% faster than the previous generation 820/821 series, though the chip is only about 10 percent faster in standard CPU-intensive tasks.

In March of 2011, he announced on Facebook that he planned to breed several Oregon zonatas—shorthand for California mountain kingsnakes (Lampropeltis zonata) caught in the Oregon wild—and sell their offspring. He included a photo of the parent animals, showing off their vivid red, black, and yellowish bands. Kruse’s fellow-collectors no doubt knew that state and federal laws made capturing and keeping the zonatas an offense. When they inquired online about the snakes’ legal status, Kruse first attempted a lie, saying that he had received them from a friend who had a permit to own them; later, he deleted the ad and photo altogether. But word had already spread through the tight-knit kingsnake community. “Everyone who saw that post was, like, Whoa, red flag,” Special Agent Paul Montuori, of the U.S. Fish an

The issue has long been a priority for conservatives, on the Court and elsewhere. But the complexion of the controversy has changed in recent years, as those on the right have become more aggressive in pressing constitutional arguments. At one point, the issues in this area were fairly straightforward, if largely symbolic. Could a Christmas crèche be displayed on municipal property? (Yes, as long as there are, say, plastic reindeer as well as the baby Jesus.) Can a student deliver a prayer before a high-school football game? (Yes, in the stands, but not over the public-address system.)

    [$] Kubernetes & security

    04-19 LWN 42

    Every conference venue has problems with the mix of room sizes, but I don't recall ever going to a talk that so badly needed to be in a bigger room as Jessie Frazelle and Alex Mohr's talk at CloudNativeCon/KubeCon Europe 2017 on securing Kubernetes.
