The urgent need for modification of scientific ranking indexes to facilitate scientific progress and diminish academic bullying [PDF]

open access: yesBioImpacts, 2020
Academic bullying occurs when senior scientists direct abusive behavior such as verbal insults, public shaming, isolation, and threatening toward vulnerable junior colleagues such as postdocs, graduate students and lab members.

Encoding-independent optimization problem formulation for quantum computing

open access: yesFrontiers in Quantum Science and Technology, 2023
We review encoding and hardware-independent formulations of optimization problems for quantum computing. Using this generalized approach, an extensive library of optimization problems from the literature and their various derived spin encodings are ...

Stability Assessment of the Rumen Bacterial and Archaeal Communities in Dairy Cows Within a Single Lactation and Its Association With Host Phenotype

open access: yesFrontiers in Microbiology, 2021
Better characterization of changes in the rumen microbiota in dairy cows over the lactation period is crucial for understanding how microbial factors may potentially be interacting with host phenotypes.

Minimal constraints in the parity formulation of optimization problems

open access: yesNew Journal of Physics, 2021
As a means to solve optimization problems using quantum computers, the problem is typically recast into an Ising spin model whose ground-state is the solution of the optimization problem.

On the Parity of the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2021
Let (Fn)n≥0 be the Fibonacci sequence. The order of appearance function (in the Fibonacci sequence) z:Z≥1→Z≥1 is defined as z(n):=min{k≥1:Fk≡0(modn)}.

Quantum Approximate Optimization With Parallelizable Gates

open access: yesIEEE Transactions on Quantum Engineering, 2020
The quantum approximate optimization algorithm (QAOA) has been introduced as a heuristic digital quantum computing scheme to find approximate solutions of combinatorial optimization problems. We present a scheme to parallelize this approach for arbitrary
