Gel Formulations of Syzygium myrtifolium Extract and Nanoparticles: Sunscreen, Antioxidant, and Skin Permeation Activities

Syzygium myrtifolium, commonly known as red shoot leaves, is rich in flavonoids with potent antioxidant and photoprotective activities, underscoring its potential as a natural source for sunscreen development. Gel formulations were prepared by incorporating both the leaf extract...

Enhancing forecasting performance in complex commodity markets: A TimeGAN-based approach applied to oil prices

This study addresses the challenge of limited historical data and high volatility in oil market forecasting by integrating synthetic time series generated with the generative adversarial networks (TimeGAN) model into the training process of a multilayer perceptron (MLP) neural ne...

Beyond Stereotypes: Exploring the Intersection of Feminist Identity and Societal Expectations in Ama Ata Aidoo’s Changes: A Love Story (1991)

Changes: A Love Story by Ama Ata Aidoo explores the intersection of feminist identity and societal expectations of African women, specifically Ghanaian women. This work examines how Esi and other characters struggle for love, autonomy, and independence, and reveals how tradition...

Predicting Dust Palliative Effectiveness on Unpaved Roads Using a Simple Laboratory Procedure

Abstract The effectiveness of palliatives such as hygroscopic salts and synthetic fluids in reducing dust emissions from unpaved roads and surfaces is well established. However, the performance of various products designed to minimize the loss of fine aggregate particles has prim...

A two-stage optimization method for wide-range single-electron quantum magnetic sensing

Quantum magnetic sensing is a new paradigm for detecting ultra-weak magnetic fields. Its protocol design concerns the devise of optimal sensing parameters to estimate the underlying signals of interest (SoI). Existing studies mainly rely on adaptive algorithms based on black-box...

Tensor Products of Multimatroids and a Brylawski-Type Formula for the Transition Polynomial

Abstract Brylawski’s tensor product formula expresses the Tutte polynomial of the tensor product of two graphs or matroids in terms of Tutte polynomials arising from the tensor factors. Analogous tensor product formulas are known for the Bollobás–Riordan and transition polynomial...

Asymptotic approach to singular solutions for the CR Yamabe equation

Abstract We study the loss of compactness for optimal functions associated with subcritical approximations of the sharp Folland–Stein–Sobolev embedding in the Heisenberg group. A key ingredient is a fine asymptotic control of the optimal functions by the Jerison–Lee extremals, wh...

Abolition of Individual Antioxidant Enzymes Did Not Affect Antibiotic-mediated Killing of Escherichia coli

Three classes of bactericidal antibiotics induce oxidative damages in addition to their interactions with specific intracellular targets. By utilizing knockout strains of Escherichia coli that lack antioxidant enzymes, we investigated whether deficiencies in the oxidant scavengin...

KURAS: A Decision Support System for the Water Need and Winter Suitability of Landscape Plants in Türkiye

The water-use classes given in landscape literature and guides are meaningful only relative to the climate in which the source was produced. The same "moderate" class requires no supplementary irrigation in a coastal city with wet summers, yet corresponds to a clear water deficit...

Predicting spectral interpolation from classical dynamics: an exact Berry–Robnik→Brody locus, its error budget, and its domain

The Brody parameter β is routinely fitted to the level spacings of a mixed quantum system and then read as a measure of its classical chaos. A fitted number cannot test the classical picture — it can only describe the spectrum. This paper asks the question the other way round: gi...

Rewriting the Structure of Its Own Improvement Mechanism: A Preregistered Causal Test of Bounded Recursive Self-Improvement

A system that rewrites its own improvement mechanism meets common definitions of recursive self-improvement whether or not the rewriting helps. In five earlier preregistered tests of a Level-4 bounded self-improving program-repair system, the rewritten mechanism was never shown t...

Annealed leap-point sampler for multimodal target distributions

Abstract In Bayesian statistics, exploring high-dimensional multimodal posterior distributions poses major challenges for existing MCMC approaches. This paper introduces the annealed leap-point sampler (ALPS), which augments the target distribution state space with modified annea...

T4 Bacteriophage Dominates T7 Bacteriophage During Co-infection of Escherichia coli C600

Co-infection is the simultaneous infection of a host cell by multiple viruses. It can result in complex competitive interactions that have significant consequences on virulence and disease dynamics. Our study investigated the intracellular mechanisms utilized for viral competitio...

The hive mind is a single reinforcement learning agent

Abstract Decision-making is an essential attribute of any intelligent agent or group. Natural systems are known to converge to effective strategies through at least two distinct mechanisms: collective decision-making via imitation of others, and trial-and-error by a single agent....

Ligninase Activity Is Not Consistently Predicted by the Presence of Manganese Coordinating Residues in Dyp-like Proteins

DypB, a characterized bacterial lignin peroxidase from Rhodococcus jostii RHA1, is thought to modify lignin using oxidized manganese as a diffusible mediator. Structural analysis has determined that manganese is bound and oxidized through a pocket near the active site that is com...

Frozen Forecast: Sign-Kernel Alignment Ranks Held-Out Adapters' Output-Matched Learning (SCAFFOLD, E5)

Laser-optic techniques for assessing blood microrheology in health and disease

Abstract Blood microrheology and microcirculation is a vast field of research focusing on the properties of blood passing through lesser vessels and capillaries. In this part of the circulatory system, red blood cells (RBCs) determine the parameters of the flow, which impact the...

Advanced Riemannian Structures for Geometric World Models: Parallel Transport, Geodesics, and Information Geometry: Volume II — Extending the Intrinsic Calculus of Latent Manifolds

This second volume extends the differential-geometric foundations of geometric world models beyond the Riemannian metric, gradient, Levi-Civita connection, and Riemann curvature tensor. It develops the theory of parallel transport and holonomy, the geodesic equation and the expon...
