Parasitic Infections and Associated Cognitive Outcome Among School‐Aged Children in Africa: A Systematic Review

Brain and Behavior, Volume 16, Issue 4, April 2026.
Parasitic infections like schistosomiasis, soil‐transmitted helminths, and malaria can impair nutrient absorption, oxygen supply, and brain function, leading to memory deficits, attention deficits, reduced intelligence quotient, weak academic performance, and motor or executive deficits.

Can a Top Predator Persist After One of the World's Largest Mining Dam Failures? Occupancy Dynamics of the Neotropical Otter in Brazil's Paraopeba River

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We evaluated the effects of the 2019 Brumadinho tailings‐dam collapse on neotropical otters (Lontra longicaudis) in Brazil's Paraopeba river using multi‐season occupancy models. Six years post‐collapse, otters showed high occupancy across impacted reaches.

The Case of Fleeting Orders and Flickering Quotes

Journal of Futures Markets, Volume 46, Issue 4, Page 629-652, April 2026.
ABSTRACT The literature controversially discusses the ambiguous motives and driving forces behind quickly cancelled limit orders (fleeting orders), which are characteristic of high‐frequency markets. In particular, manipulative and dysfunctional characteristics are feared. We analyze top‐of‐book fleeting orders—so‐called flickering quotes—and show with

Integrating Biological Architecture and Biomaterial Function: Exploring the Native Hydrogel Structure of Brown Seaweed

Macromolecular Bioscience, Volume 26, Issue 4, April 2026.
This study explores the natural internal structure of brown seaweed and how it influences material behavior. By preserving and reassembling the seaweed's native architecture, hydrogels and foams with high liquid absorption, porosity, and shape recovery were created using minimal processing.

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

PROTEOMICS, Volume 26, Issue 4, Page 7-22, April 2026.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Optimization of Hot and Cold‐Water Extractions of Cistus salviifolius L. for Enhanced Phenolic Content and Antimicrobial Efficacy

ChemistrySelect, Volume 11, Issue 13, 6 April 2026.
This study optimized cold and hot water extractions for maximizing phenolic content and antibacterial activity against S. aureus and P. aeruginosa. Hot water yielded higher total phenolics and were more effective against P. aeruginosa. Conversely, cold water enriched specific ellagitannins (punicalagin and cistusin), showing potent, targeted ...

Mismatch between the progression of the mathematics course and the level of mathematics required to do advanced physics [PDF]

, 2010
Whenever students appear to have trouble with mathematics in their physics courses, they either hate physics or fear it. The blame for this plight could be due to the structure of the mathematics and physics curricula or the incompetence of the teachers.

Converting Binary Floating‐Point Numbers to Shortest Decimal Strings: An Experimental Review

Software: Practice and Experience, Volume 56, Issue 4, Page 462-478, April 2026.
ABSTRACT Background When sharing or logging numerical data, we must convert binary floating‐point numbers into their decimal string representations. For example, the number π might become 3.1415927. Engineers have perfected many algorithms for producing such accurate, short strings.
