Joint Modulation Classification and User Number Detection for Multiuser MIMO-STBC Systems

Information, 2016
The research on non-cooperative multiuser multiple-input multiple-output with space-time block code (MIMO-STBC) communication systems is a challenging and important task. However, to our knowledge, there is little report of this topic.

Locked Pollen, Unchanged Buzzes: Bumblebee Foraging Behavior Persists Despite Pollen Restriction in a Poricidal Legume

New Zealand Journal of Zoology, Volume 53, Issue 4, December 2026.
In plants that offer pollen as their sole floral reward, this resource is finite and nonreplenishable, making such plants useful systems for studying how resource availability across flowers shapes pollinator behavior. Because tropical ecosystems of the Global South harbor exceptionally diverse plant–pollinator interactions, understanding pollinator ...

Kalman Filter-Based Chip Differential Blind Adaptive Multiuser Detection for Variably Mobile Asynchronous Underwater Multiuser Communications

IEEE Access, 2018
To mitigate the inter-symbol interference (ISI), multiple access interference (MAI), and the effect of different Doppler shifts within a data package incurred in variably mobile asynchronous underwater multiuser communications (VMAUMC), a Kalman filter ...

High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

SVD Aided Joint Transmitter and Receiver Design for the Uplink of Multiuser Detection Assisted MIMO Systems,

, 2008
A novel singular value decomposition (SVD) aided uplink (UL) multiuser MIMO system is proposed. In contrast to the traditional minimum mean square error (MMSE) or zeroforcing (ZF) multiuser detection (MUD) technique, the proposed method exploits the ...

Synthesis, Antiparasitic Activity, and ADME Profile of Morpholinephenylbenzamides: A Pharmacological Study Against Chagas Disease and Visceral Leishmaniasis

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
Hit‐to‐lead optimization of morpholinephenylbenzamides reveals key structure–activity relationships against Trypanosoma cruzi and Leishmania infantum. Potency, selectivity, and ADME properties are differentially improved across the series, identifying compounds 20, 24, and 16 as complementary templates for the future design of dual antiparasitic leads.

From Pinus Elliottii Biorefinery Fractions to High‐Quality Green Laser‐Induced Graphene: The Role of Hydroxyethyl Cellulose‐Assisted Matrix Engineering

Advanced Sustainable Systems, Volume 10, Issue 10, October 2026.
Beyond green Laser‐Induced Graphene (gLIG) production, this work establishes a direct link between biorefinery operations and gLIG manufacturing, demonstrating how renewable forest biomass can be fractionated, upgraded, and transformed into advanced carbon nanomaterials within a single valorization framework. ABSTRACT Green laser‐induced graphene (gLIG)
