Kissing numbers and transference theorems from generalized tail bounds [PDF]
, 2019 We generalize Banaszczyk's seminal tail bound for the Gaussian mass of a lattice to a wide class of test functions. From this we obtain quite general transference bounds, as well as bounds on the number of lattice points contained in certain bodies.

On The Ladder Bethe-Salpeter Equation
, 2003 The Bethe-Salpeter (BS) equation in the ladder approximation is studied within a scalar theory: two scalar fields (constituents) with mass $m$ interacting via an exchange of a scalar field (tieon) with mass $\mu$.

An Empirical Analysis of Determinants of Balance of Payments in Pakistan [PDF]
International Journal of Management, Accounting and Economics, 2018 This study investigates the determinants of balance of payments for Pakistan between 1981 and 2016. This paper using ARDL bounds testing approach. ARDL technique is used to find the short run and long run relationship of these variables with BOP.

Minimax lower bounds for linear independence testing [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 Linear independence testing is a fundamental information-theoretic and statistical problem that can be posed as follows: given $n$ points $\{(X_i,Y_i)\}^n_{i=1}$ from a $p+q$ dimensional multivariate distribution where $X_i \in \mathbb{R}^p$ and $Y_i \in\mathbb{R}^q$, determine whether $a^T X$ and $b^T Y$ are uncorrelated for every $a \in \mathbb{R}^p,

Quintessence Saves Higgs Instability
, 2018 We study a model where quintessence potential $e^{-\xi\phi}$ coupled to Higgs potential. We calculate the evolution of the quintessence, and track the running of the effective Higgs self-coupling.

Lower bounds for adaptive linearity tests [PDF]
, 2008 Linearity tests are randomized algorithms which have oracle access to the truth table of some function f, and are supposed to distinguish between linear functions and functions which are far from linear.

Precision Study of Positronium: Testing Bound State QED Theory
, 2003 As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theory is not so well understood and bound state approaches deserve highly ...

On the Upper Bounds of Test Statistics for a Single Outlier Test in Linear Regression Models
Journal of Applied Mathematics, 2021 A bewildering large number of test statistics have been found for testing the presence of an outlier in multiple linear regression models. Exact critical values of these test statistics are not available, and approximate ones are usually obtained by the ...
