Minimum Eigenvalue Based Covariance Matrix Estimation with Limited Samples

2024 IEEE Wireless Communications and Networking Conference (WCNC)
In this paper, we consider the interference rejection combining (IRC) receiver, which improves the cell-edge user throughput via suppressing inter-cell interference and requires estimating the covariance matrix including the inter-cell interference with high accuracy.

Entanglement of A Qubit‐Qutrit System: Impact of Ohmic Noise

Advanced Physics Research, EarlyView.
The dynamics of quantum correlations in a hybrid qubit–qutrit system subjected to an Ohmic noisy environment are investigated in this study. The significance of open quantum systems and the rationale behind researching decoherence effects on hybrid quantum architectures are discussed in the introduction. The system Hamiltonian, the interaction with the

Notes on the minimum eigenvalue of the fan product

Journal of Physics: Conference Series
Abstract This article aims to discuss the minimum eigenvalue of the Fan product. We derive a new lower bound for the minimum eigenvalue based on the previous result and compare it with related conclusions. Finally, we verify our findings with a specific example.

A Hybrid Semi‐Inverse Variational and Machine Learning Approach for the Schrödinger Equation

Advanced Physics Research, EarlyView.
A hybrid semi‐inverse variational and machine‐learning framework is presented for solving the Schrödinger equation with complex quantum potentials. Physics‐based variational solutions generate high‐quality training data, enabling Random Forest and Neural Network models to deliver near‐perfect energy predictions.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

The Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Integrating whole‐bone and regional analyses to understand human scapular growth

The Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...
