Time course of muscle hypertrophy with and without progressive overload

To compare the time course of muscle hypertrophy during resistance training with progressive overload (PROG) or without overload progression (N-PROG), 31 healthy untrained young adults completed a randomized within-subject trial. Each participant trained one leg with PROG and the...

Volcanic textures control the mechanical behaviour of Mesoamerican obsidians

Abstract Obsidian—natural volcanic glass—was exploited for millennia and played a central role in the technological and socio-economic development of pre-Hispanic societies across Mesoamerica. The selection of obsidian from specific deposits has been linked to differences in visu...

Ultrahigh strength enabled by dual-scale L12 precipitation and back-stress strengthening in an LPBF-fabricated (CoCrNi)94Al3Ti3 medium-entropy alloy

Simultaneously achieving ultrahigh strength and useful tensile ductility in precipitation-strengthened medium-entropy alloys requires control over not only precipitate characteristics but also the recovery and recrystallization of metastable additively manufactured microstructure...

EXPRESS: Dissociating attentional and working memory load in memory for emotional faces

There is evidence that both general attention load and face-specific working memory load modulate the processing of emotional faces, but the contribution of each remains uncertain. Here, we investigated how these resources modulate the recognition of emotional faces in working me...

When perception meets reality: explaining measured food waste through consumer behavior in a university dining hall

Food waste (FW) in university dining halls generates significant environmental and economic impacts, yet most studies rely on self-reported measures and rarely combine behavioral perceptions with objective waste data. This study investigates the determinants of consumer FW by int...

Atrazine dissipation and soybean phytotoxicity following burndown applications of atrazine + mesotrione + triclopyr for Conyza spp. management

This study aimed to evaluate the effectiveness of (atrazine + mesotrione) + triclopyr on Conyza spp. at different intervals between application and soybean sowing, as well as the phytotoxic effects of residual atrazine on soybeans. The field experiment, conducted in a randomized...

Divergent Diagrams of Folds Associated with Reflections

Abstract We analyze divergent diagrams of k -fold map-germs at $$(\mathbb {C}^n,0)$$ ( C n , 0 ) , for $$k, n \ge 2,$$ k , n ≥ 2 , associated with reflections, adapting to the complex setting the theory of folds associated with involutions at $$(\mathbb {R}^n,0)$$ ( R n , 0 ) . I...

From Surface Buffering to Bulk Ion Exchange: Mapping the Acid Response of Potassium Poly(Heptazine Imide) (K-PHI)

Abstract Potassium poly(heptazine imide) (K-PHI) is a promising material for photocatalysis and energy storage, yet its application in aqueous media is limited by protonation. Cation exchange to protonated poly(heptazine imide) (H-PHI) causes structural and optoelectronic changes...

The role of solid-state phase transformation mechanisms on the hydrogenation of multicomponent TiZrFeNi and Ni-Zr binary alloys

This study investigates solid-state phase transformations during hydrogenation of multicomponent TiZrFeNi and Ni-Zr binary alloys sharing the Ni 10 Zr 7 phase. The multicomponent alloy was designed using semi-empirical criteria and predicted by CALPHAD calculations. The phase equ...

Combined application between remediation and bioremediation enhances soil xenobiotics decontamination

Atrazine (ATZ) is a herbicide extensively used in Brazilian agriculture, yet its environmental persistence poses severe risks to soil health and non-target organisms. This perspective article proposes an integrated remediation strategy combining biochar (BC), Canavalia ensiformis...

A First-Principles Study of Surface-Dependent Synergy between H2O and O2 on Silver-Based Oxide Semiconductors

Abstract Silver-based ternary oxides, including Ag3PO4, β-Ag2MoO4, and the α- and γ-Ag2WO4 polymorphs, are promising photocatalysts for generating reactive oxygen species (ROS). In this work, density functional theory calculations were employed to disclose the atomic site-specifi...

Rheological, Viscoelastic, and Dynamic Mechanical Behavior of ZnO-Filled and MA-Modified PP/SEBS Filaments for Fused Filament Fabrication

Abstract Immiscible polyolefin–elastomer blends often exhibit limited impact resistance and unstable melt-flow behavior due to weak interfacial adhesion and inefficient stress transfer between phases. These limitations are relevant for fused filament fabrication (FFF), where fila...

Cladocerans and macrophytes: network and resistance to extinctions

Abstract Macrophytes are important in structuring various aquatic communities, particularly cladocerans. Our findings highlight that plant structural complexity and functional life forms (specifically free-floating and submerged species) act as key drivers of interaction density...

Epoxidation of ent-pimara-8(14),15-dien-19-oic acid by whole cells of the endophytic fungus Aspergillus sclerotiorum

Abstract The diterpene ent -pimara-8(14),15-dien-19-oic acid ( 1 ) was converted into four oxidized diterpenes, 15,16-epoxy- ent -pimar-8(14)-en-19-oic acid ( 1a ), 15,16-epoxy-17-hydrxy- ent -pimar-8(14)-en-19-oic acid ( 1b ), 15,16-dihydroxy- ent -pimar-8(14)-en-19-oic acid ( 1...

Warming causes higher bilateral asymmetry in aquatic hemipterans from geothermal streams

Abstract Increase in temperature associated with climate change may alter community structure and disrupt developmental stability in ectothermic organisms. Using a natural geothermal gradient (20.6–40.3 °C) in Neotropical streams in central-western Brazil, we investigated how war...

Explainable artificial intelligence for deep learning-based delamination detection in Carbon Fiber Reinforced Polymer composites

The heterogeneous and anisotropic nature of Carbon Fiber Reinforced Polymers (CFRP) introduces challenges in characterizing failure mechanisms, particularly delamination, in advanced composite engineering structures used across multiple industrial sectors. Although deep learning...
