Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Space-Time Codes and Concatenated Channel Codes for Wireless Communications

open access: yes, 2002
Following a brief historical perspective on channel coding, an introduction to space–time block codes is given. The various space–time codes considered are then concatenated with a range of channel codecs, such as convolutional and block-based turbo ...

Non-binary protograph low-density parity-check codes for space communications

open access: yes, 2012
Protograph-based non-binary low-density parity-check (LDPC) codes with ultra-sparse parity-check matrices are compared with binary LDPC and turbo codes (TCs) from space communication standards.

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

On Rate-Compatible Punctured Turbo Codes Design

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose and compare some design criteria for the search of good systematic rate-compatible punctured turbo code (RCPTC) families. The considerations presented by S. Benedetto et al.

Scalable video/image transmission using rate compatible PUM turbo codes

open access: yes, 2007
The robust delivery of video over emerging wireless networks poses many challenges due to the heterogeneity of access networks, the variations in streaming devices, and the expected variations in network conditions caused by interference and coexistence.

Disparities in AI‐Based Prior Authorization for Head and Neck Reconstruction: A Large Language Model Analysis

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Large language models (LLM) are being rapidly integrated into healthcare, particularly to streamline time‐ and labor‐intensive administrative processes. However, the potential for artificial intelligence (AI) systems to demonstrate bias when employed for insurance authorization remains poorly understood.

Iterative Vector Tracking of Turbo- or LDPC- Coded High-level Constellations on a Nonlinear Satellite Channel

open access: yes, 2003
Interactive multimedia wideband satellite services will require the adoption of Turbo or Low-Density Parity-Check (LDPC) coded spectrally-efficient high-level modulation techniques in future satellite transmission standards.

Combined Serially Concatenated Codes and MMSE Equalization: an EXIT Chart Aided Perspective

open access: yes, 2006
Iterative Minimum Mean Square Error (MMSE) equalization and channel decoding is appealing, since it exhibits a lower complexity than maximum a posteriori (MAP) turbo equalization.
