Almost optimal measurement scheduling of molecular Hamiltonian via finite projective plane

Physical Review Research
We propose an efficient and almost optimal scheme for measuring molecular Hamiltonians in quantum chemistry on quantum computers, which requires 2N^{2} distinct measurements in the leading order with N being the number of molecular orbitals.

Comparative performance for thermoelectric refrigerators with radiative and Newtonian heat transfer laws

Case Studies in Thermal Engineering, 2022
Models of multi-element thermoelectric refrigerator (TER) with radiative heat transfer law (RHT) and Newtonian heat transfer law (NHT) are established based on finite time thermodynamics.

An Almost Optimal Unrestricted Fast Johnson-Lindenstrauss Transform [PDF]

ACM Transactions on Algorithms, 2011
The problems of random projections and sparse reconstruction have much in common and individually received much attention. Surprisingly, until now they progressed in parallel and remained mostly separate. Here, we employ new tools from probability in Banach spaces that were successfully used in the context of sparse reconstruction to ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Estimation of Optimal Commodity Tax Rates in Iran [PDF]

Faslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2008
This study estimates optimal commodity tax rates regarding efficiency and social justice. A many- person Ramsey rule and Bergson – Samuelson social welfare function are used for estimating optimal tax rates.

Constructing Odd-Variable Rotation Symmetric Boolean Functions With Optimal AI and Higher Nonlinearity

IEEE Access, 2019
As a part of the field of cryptography, rotation symmetric Boolean functions have rich cryptographic significance. In this paper, based on the knowledge of integer compositions, we present a new construction of odd-variable rotation symmetric Boolean ...

Almost-optimal computational-basis-state transpositions

Physical Review A
We give an explicit construction to perform any $n$-qubit computational basis state transposition using $Θ(n)$ gates. This nearly coincides with the lower bound $Ω(n/\log(nd))$ on worst-case and average-case gate complexity to perform transpositions using a $d$-element gate-set, which we also prove.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Almost Optimal Differentiation Using Noisy Data

Journal of Approximation Theory, 1996
Differentiation of functions \(f\) is studied if only inaccurate data \(f(t_i)+\varepsilon_i\) are available, the \(f\) being stochastic and corrupted by some noise \(\varepsilon_i\), the function \(f\) being observed at a finite number of points. Expressions are derived for the derivative \(f^{(k)}\) either at a single point \(t\in [0,1]\) or on the ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
