Ballistic spin transport through waveguides, with symmetric or asymmetric double stubs attached to them periodically, is studied systematically in the presence of a weak spin-orbit coupling that makes the electrons precess. By an appropriate choice...
We consider Toeplitz operators defined on a concave corner-shaped subset of the square lattice. We obtain a necessary and sufficient condition for these operators to be Fredholm. We further construct a Fredholm concave corner Toeplitz operator of ind...
Finally got out to check out LAX/MTC, and went from downtown and back via the big square: J -> C -> K -> E. The new station is great, and there were already a fair number of people there, bot...
Salzburg is the city where W. A. Mozart was born and the shooting location for "The Sound of Music". The narrow lanes and broad squares of this baroque city have taken their deserved place on the …
The Square Kilometre Array (SKA) project is an international effort to build the world's most sensitive radio telescope operating in the 50 MHz to 14 GHz frequency range. Construction of the SKA is divided into phases, with the first phase (SKA1) acc...
We consider an aspect of the open problem: Does every square-integrable function on SU(2) have an almost everywhere convergent Fourier series? Let 0 < alpha < 1. We show that to each countable set E in SU(2) there corresponds an alpha-Holder continuo...
We consider the open problem: Does every square-integrable function f on a compact, connected Lie group G have an almost everywhere convergent Fourier series? We prove a general theorem from which it follows that if the integral modulus of continuity...

On 15 June 2023, Google entered into a definitive agreement with Squarespace, indicating their intent to purchase all domain registrations and related customer accounts from Google Domains.
For the sparsity-rank-aware least squares estimations, the LiGME (Linearly involved Generalized Moreau Enhanced) model was established recently in [Abe, Yamagishi, Yamada, 2020] to use certain nonconvex enhancements of linearly involved convex regula...
The Laplacian in spherical coordinates contains the squared radial momentum operator $ p_r^2 = - r^{-1} \partial_r^2 r $ which is Hermitian and positive. However as has been pointed out by various authors the ``radial momentum operator" $ - i r^{-1...
first, by Daichi Matsue, was published between June 2014 and March 2015. The second, by Makoto Fugetsu, has been published by Square Enix between October

Jakob Sand - Partner, BIG Inside, a spacious foyer serves as the building’s central square, filled with natural light. A grand staircase connects the foyer to the main auditorium, while overlapping levels …

A coinless quantisation procedure of general reversible Markov chains on graphs is presented. A quantum Hamiltonian H is obtained by a similarity transformation of the fundamental transition probability matrix K in terms of the square root of the rev...
The critical behavior of the O(2) model on dilute Levy graphs built on a 2D square lattice is analyzed. Different qualitative cases are probed, varying the exponent rho governing the dependence on the distance of the connectivity probability distribu...
Hearts IV is an upcoming action role-playing game developed and published by Square Enix. It will be the fifteenth installment in the Kingdom Hearts series
Plus-Minus. Means a quantity of same magnitude can have either a positive or a negative value. As commonly found in square roots such as $$\\sqrt[2]{625}= +-25$$. Here is an Wikipedia SVG-exampl...
We propose a penalized least-squares method to fit the linear regression model with fitted values that are invariant to invertible linear transformations of the design matrix. This invariance is important, for example, when practitioners have categor...
