Effects of Mono‐ and Dicapsaicinoid Functionalization on the Physicochemical Properties and Antimicrobial Photodynamic Activity of Protoporphyrin IX

open access: yesChemMedChem, Volume 21, Issue 17, 14 September 2026.
Capsaicin functionalization of Protoporphyrin IX influences aggregation behavior, lipophilicity, and photodynamic activity. A monosubstituted derivative exhibits enhanced antimicrobial photoinactivation of Staphylococcus aureus, whereas increased functionalization does not improve efficacy.

Decision-Feedback Multiuser Detection in Multicell Multicarrier DS-CDMA Systems with/without BS Cooperation

open access: yes, 2013
—In this contribution, we investigate the signal detection in the multicarrier direct-sequence code-division multiple-access (DS-CDMA) systems employing both time (T)-domain and frequency (F)-domain spreading, which are referred to as the TF/MC DS-CDMA ...

Radio‐Frequency Front‐End‐Free Hybrid Code‐Division and Space‐Division Wireless Multiplexing Using Space‐Time‐Coding Metasurface

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
This work constructs a radio‐frequency front‐end‐free hybrid code‐division and space‐division‐multiplexing wireless communication system built on programmable space‐time‐coding metasurfaces. Orthogonal pseudo‐random codes reliably separate overlapped multistream signals that share identical frequency, time, and spatial resources.

Impact of 2D versus 3D fibroblast models on Leishmania species invasion in vitro: Rab5 dynamics and actin activity in initial infection

open access: yesFrontiers in Cellular and Infection Microbiology
BackgroundThe protozoan Leishmania, in addition to infecting phagocytic cells such as macrophages, can also invade non-professional phagocytic cells like fibroblasts, a process previously described in 2D models.

BMT4me En Español: Multisite Feasibility and Usability Testing of a Spanish‐Language mHealth Adherence Support App for Spanish‐Speaking Caregivers of Children After Hematopoietic Stem Cell Transplantation and Cancer Treatment

open access: yesPediatric Blood &Cancer, Volume 73, Issue 9, September 2026.
ABSTRACT Background Medication nonadherence during the first 100 days after pediatric hematopoietic stem cell transplantation (HSCT) and during oncology treatment increases risk for complications. BMT4me is a caregiver‐facing mobile health (mHealth) application providing medication reminders, symptom tracking, and note‐taking features to support ...

Adaptive near minimum error rate training for neural networks with application to multiuser detection in CDMA communication systems

open access: yes, 2005
Adaptive training of neural networks is typically done using some stochastic gradient algorithm that tries to minimize the mean square error (MSE). For many applications, such as channel equalization and code-division multiple-access (CDMA) multiuser ...
