Non-Uniform and Non-Random Binding of Nucleoprotein to Influenza A and B Viral RNA

open access: yesViruses, 2018
The genomes of influenza A and B viruses have eight, single-stranded RNA segments that exist in the form of a viral ribonucleoprotein complex in association with nucleoprotein (NP) and an RNA-dependent RNA polymerase complex.

Direct position determination algorithm for non‐circular sources in the presence of mutual coupling and its theoretical performance analysis

open access: yesIET Signal Processing, 2023
This article proposes a direct position determination (DPD) algorithm for non‐circular sources observed by a moving array using the self‐calibration technique in the presence of mutual coupling.

Integral points on elliptic curves and explicit valuations of division polynomials

open access: yes, 2014
Assuming Lang's conjectured lower bound on the heights of non-torsion points on an elliptic curve, we show that there exists an absolute constant C such that for any elliptic curve E/Q and non-torsion point P in E(Q), there is at most one integral ...

Information Theoretic Characterization of Uncertainty Distinguishes Surprise From Accuracy Signals in the Brain

open access: yesFrontiers in Artificial Intelligence, 2020
Uncertainty presents a problem for both human and machine decision-making. While utility maximization has traditionally been viewed as the motive force behind choice behavior, it has been theorized that uncertainty minimization may supersede reward ...

Free Energy of a Dilute Bose Gas: Lower Bound

open access: yes, 2006
A lower bound is derived on the free energy (per unit volume) of a homogeneous Bose gas at density $\rho$ and temperature $T$. In the dilute regime, i.e., when $a^3\rho \ll 1$, where $a$ denotes the scattering length of the pair-interaction potential ...

Direction-of-Arrival Estimation Based on Variational Bayesian Inference Under Model Errors

open access: yesRemote Sensing
The current self-calibration approaches based on sparse Bayesian learning (SBL) demonstrate robust performance under uniform white noise conditions. However, their efficacy degrades significantly in non-uniform noise environments due to acute sensitivity

Bandwidth Efficiency Maximization for Single-Cell Massive Spatial Modulation MIMO: An Adaptive Power Allocation Perspective

open access: yesIEEE Access, 2017
The concept of massive spatial modulation aided multiple-input multiple-output (SM-MIMO) systems, where the base station (BS) is equipped with a large number of antennas and simultaneously serves several multi-antenna users that employ SM for their ...

New Non-Uniform Lower Bounds for Uniform Classes.

open access: yes, 2016
We strengthen the nondeterministic hierarchy theorem for non-deterministic polynomial time to show that the lower bound holds against sub-linear advice. More formally, we show that for any constants d and d' such that 1 <= d < d', and for any time-constructible bound t=o(n^d), there is a language in NTIME(n^d) which is not in NTIME(t)/n^{1/d ...

The First-Order Theory of Ground Tree Rewrite Graphs [PDF]

open access: yesLogical Methods in Computer Science, 2014
We prove that the complexity of the uniform first-order theory of ground tree rewrite graphs is in ATIME(2^{2^{poly(n)}},O(n)). Providing a matching lower bound, we show that there is some fixed ground tree rewrite graph whose first-order theory is hard ...
