Limited continuous continental records and complex climatic interactions hinder a comprehensive understanding of paleoclimatic and paleoenvironmental conditions during the Last Glacial Maximum (LGM) in the tropics. Adjacent to the currently semi-arid northeastern Brazil (NEB), a...

Abstract Platinum (Pt) is an emerging environmental contaminant due to its increasing anthropogenic use, yet the processes controlling its speciation remain poorly understood. Here, we investigate Pt redox transformations in the presence of natural organic matter (NOM) using X-ra...

A cross-species atlas platform for comparative neuroscience in teleost fish
Abstract Uncovering general principles connecting neural circuits to behaviour requires comparative brain analyses across species. To advance these efforts, we developed a standardised workflow and a unified brain atlas platform for the quantitative comparison of neural structure...

Emergent memory in cell-like active systems
Active systems across scales, ranging from molecular machines to human crowds, are usually modeled as assemblies of self-propelled particles driven by internally generated forces. However, these models often assume memoryless dynamics. Here, guided by the example of living cells,...

Pentafluorophenyl triflate has been explored as a highly absorbing neutral photoacid generator (PAG) candidate for next-generation chemically amplified resists used in extreme ultraviolet (EUV) lithography. Although increased fluorination enhances EUV absorption, this study demon...

Critical point representation of the mutual information in the sparse stochastic block model
We consider the problem of recovering the community structure in the stochastic block model. We aim to describe the mutual information between the observed network and the actual community structure as the number of nodes diverges while the average degree of a given node remains...

Adaptive multilevel stochastic approximation of the value-at-risk
Crépey, Frikha and Louzi (Finance Stoch. (2025) 1015–1074) introduced a multilevel stochastic approximation scheme to compute the value-at-risk of a financial loss that is only simulatable by Monte Carlo. The best complexity of the scheme is in O(ε−52), ε>0 being a prescribed acc...

Ginzburg–Landau Minimizers with High Topological Degrees in an Annulus
Abstract. Motivated by recent experiments on fermionic rings, we study the asymptotic behavior of minimizers of the Ginzburg–Landau (GL) energy in an annulus with a Dirichlet data which depends on the GL parameter on the outer boundary. We show that there is a critical degree of...

An infinite-times renewal equation
In neuroscience, the time elapsed since the last discharge has been used to predict the probability of the next discharge. Such predictions can be improved taking into account the last two discharge times, and preferentially more. Such multi-times renewal processes arise in many...

ALE-based finite element modeling of needle-punching using embedded 1D yarns in a 3D preform
Needle-punching is widely used to introduce through-thickness reinforcement into fibrous preforms for composite materials. During the process, barbed needles repeatedly penetrate stacked layers and transfer fibers from the in-plane directions toward the thickness direction, progr...

This study aimed to develop bioactive pectin-based films incorporating Deverra tortuosa (D. tortuosa) essential oil (EO) nanoemulsions stabilized by sodium caseinate for potential active food packaging applications. EO nanoemulsions were incorporated into a pectin–maltodextrin ma...

Our article studies the main features of a constitutionalism trend reflected in the influence of private interest groups over jurisdictional expansion and interpretative advances operated by the European Court of Human Rights. We posit that liberal interests’ litigation bears pot...

Early systemic intervention for vitiligo: A prospective bicentric interventional study
BACKGROUND: Vitiligo is a complex autoimmune skin disease characterized by loss of melanocytes resulting in the appearance of white skin patches. Recent advances in treatment have improved patient outcomes, but the process of repigmentation is prolonged and often incomplete. OBJE...

Abstract We present multiwavelength observations and analysis of SN 2024iss, a Type IIb supernova (SN IIb) located at ∼14 Mpc. The first Zwicky Transient Facility detection of SN 2024iss is ∼40 minutes after first light (one of the earliest detections of a SN IIb to date) and a H...

Human polymorphonuclear neutrophils (PMNs) are pivotal in the initiation and resolution of inflammation, playing an essential role in maintaining tissue homeostasis and facilitating repair. This study investigates how polymers influence PMNs apoptosis, a favourable step for the r...

Abstract Ribonucleic acid (RNA) molecules fold into complex, highly dynamic three-dimensional conformational structures that govern their biological activities. Chemical probing methods, such as SHAPE (selective 2′-hydroxyl acylation analyzed by primer extension), provide structu...

A Review of Input Current Ripple Reduction Techniques in Non-Isolated DC–DC Boost Converters
Input current ripple reduction in DC-DC boost converters is a persistent challenge because input current ripples are driving up filter requirements, electromagnetic interference (EMI), and stress on sources and loads. This ultimately limits power density and efficiency in many ap...

Abstract ZnSe is a cornerstone shell material for enhancing the efficiency and stability of quantum dots (QDs). However, the chemical mechanisms governing detrimental zinc vacancy (VZn) formation remain unclear, limiting the predictive synthesis of high-quality heterostructures....

Incorporating sliding and local rigidity constraints in neural-based image registration
Image registration is widely used in various applications to estimate the deformations of moving structures in image pairs acquired at different times. Spatial regularization strategies often take a one-size-fits-all approach by imposing uniform deformation constraints across the...
