Donald Trump’s economy went charging off a cliff
after his April 2 “Liberation Day” tariffs, which
—despite endless tweaks, revisions, abrupt extensions, and equally abrupt reversals
—are gradually settling into a new status quo
in which the costs of global trade are far higher than before.
But we’re just starting to feel the true impact of that status quo.
-- Because until recently, a series of ameliorating factors have kept things looking artificially norm…

Trump’s Tariff Pain Is Knocking at Your Door
The stopgap measures that have so far protected consumers from feeling the effects of tariffs are nearly at an end.

Odd-even parity dependent transport in an annular Kitaev chain
We investigate the impact of magnetic flux and the odd-even parity of lattice points $N$ on electron transport in an annular Kitaev chain, with an explanation provided from the energy band perspective. Three transport mechanisms including direct transmission (DT), local Andreev reflection (LAR) and crossed Andreev reflection (CAR) are considered. In particular, the connection configuration of electrodes to different lattice sites is studied, where the case that the two electrodes connected to t…

Comparative Studies of Quantum Annealing, Digital Annealing, and Classical Solvers for Reaction Network Pathway Analysis and mRNA Codon Selection
For various optimization problems, the classical time to solution is super-polynomial and intractable to solve with classical bit-based computing hardware to date. Digital and quantum annealers have the potential to identify near-optimal solutions for such optimization problems using a quadratic unconstrained binary optimization (QUBO) problem formulation. This work benchmarks two use cases to evaluate the utility of QUBO solvers for combinatorial optimization problems, in order to determine if…

Quantum Prime Factorization: A Novel Approach Based on Fermat Method
In this paper, we introduce a novel quantum algorithm for the factorization of composite odd numbers. This work makes two significant contributions. First, we present a new improvement to the classical Fermat method, fourfold reducing the computational complexity of factoring. Second, we reformulate Fermat factorization method as an optimization problem suitable for Quantum Annealers which allowed us to factorize 8,689,739, the biggest number ever factorized using a quantum device to our knowle…

Stability and bifurcation of Navier-Stokes equations in an annular domain with mixed boundary conditions
We study the existence and stability of non-trivial steady-state solutions to the two-dimensional incompressible Navier-Stokes equations in an annular domain $Ω= B(0,b) \setminus \overline{B(0,a)}$ with radii $b>a>0$.The outer boundary $\partial B(0, b)$ is subject to the free condition, while the inner boundary $\partial B(0, a)$ obeys a Navier-slip condition with effective slip length $α> 0$. Our main results are fourfold. First, we establish global-in-time strong solutions and derive a sha…

Annular SL(2) and SL(3) web algebras
We use annular foam TQFTs introduced by the first two authors to define equivariant $SL(2)$ and $SL(3)$ web algebras in the annulus. To a diagram of a tangle in the thickened annulus we assign a complex of bimodules over these algebras whose chain homotopy type is an invariant of the tangle. Several properties of algebras and bimodules are established. An essential technical part of the paper provides a bijective correspondence between non-elliptic annular $SL(3)$ webs and closed paths in the $…

From annular to toroidal knotoids and their bracket polynomials
In this paper we study the theory of multi-knotoids of the annulus and of the torus. We present first their equivalence relation, building it up from the theory of planar knotoids to the theory of toroidal knotoids through the theory of annular knotoids. We introduce the concept of lifting annular and toroidal knotoids and examine inclusion relations arising naturally from the topology of the supporting manifolds. We also introduce the concept of mixed knotoids as special cases of planar knotoi…
