A Knowledge Service System for Foundation Pit Engineering Based on LoRA and RAG

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Foundation pit engineering involves a complex system of technical standards. Yet practitioners often struggle to retrieve relevant provisions and interpret them efficiently during construction decision‐making. To address these challenges, this paper presents a knowledge service system that integrates low‐rank adaptation (LoRA) with retrieval‐augmented ...

Timing-Free Blind Multiuser Detection for Multicarrier DS/CDMA Systems with Multiple Antennae

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
The problem of blind multiuser detection for an asynchronous multicarrier DS-CDMA system employing multiple transmit and receive antennae over a Rayleigh fading channel is considered in this paper. The solutions that we develop require prior knowledge of

Deep Learning‐Based Passive Localization System Using Radio Tomography Images and Wi‐Fi RSSI

open access: yesInternational Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Passive localization is an important technology within Internet of Things (IoT) applications that allows for tracking and monitoring of people without needing active transmitters. This feature proves useful in privacy‐conscious areas like security and healthcare, where active tracking or wearable devices are not practicable.

A multidimensional phase-locked loop for blind multiuser detection [PDF]

open access: yesIEEE Transactions on Signal Processing, 2002
This paper concerns the problem of blind multiuser detection, a special case of the blind source separation problem in which the source signals have finite alphabets. Specifically, we address the problem of identifying and resolving the n/spl times/n unitary matrix ambiguity U that results from whitening the receiver observations, where n is the number

HoBi‐Like Pestivirus Is the Most Frequently Detected Pestivirus in Cattle Across Different Regions of Brazil

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Pestiviruses are major viral pathogens of cattle worldwide, causing substantial economic losses and posing persistent challenges to animal health and productivity. Brazil hosts the world’s largest cattle population and represents a strategic setting for the emergence and maintenance of bovine pestiviruses.

Blind Direct Multiuser Detection for Uplink MC-CDMA: Performance Analysis and Robust Implementation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
We consider the problem of blind (i.e., without training sequences) linear mitigation of multiple-access interference in the uplink of quasi-synchronous multicarrier code-division multiple-access (MC-CDMA) systems.

The thoracic perivascular adipose tissue spontaneously induces vasoconstriction through activation of α1‐adrenoceptors

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 19, Page 4535-4552, October 2025.
Background and Purpose Although perivascular adipose tissue (PVAT) contains substances with contractile properties, its actions on the vascular tone are associated with the release of anticontractile substances. We hypothesize that procontractile PVAT products also exert direct effects on vascular tone. Experimental Approach Thoracic aortas from Wistar

Long‐Term Maintenance of High Neutralizing Anti‐SARS‐CoV‐2 Antibodies Titres in Mares’ Milk and Offspring Serum After Pregnant Mares Immunization With SARS‐CoV‐2 Spike Protein

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
This study investigated the total and neutralizing antibodies transferred to offspring from three mares from Vital Brazil Institute that were pre‐immunized with recombinant SARS‐CoV‐2 trimeric spike protein. They became pregnant during the immunization protocol.
