Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

open access: yesJournal of Raman Spectroscopy, EarlyView.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Compound‐Specific Stable Isotope Analysis Improves the Association Between Dairy Fatty Acid Biomarkers and Dairy Intake: A Secondary Analysis

open access: yesLipids, EarlyView.
ABSTRACT Increasing evidence suggests that dairy consumption may decrease the risk of chronic diseases. However, this association remains unclear due to methodological limitations. As a part of a secondary analysis, we used compound‐specific stable isotope analysis to increase the accuracy of the dairy FA biomarkers (15:0, 17:0), considering that each ...

Germanium‐Based Mid‐Infrared Integrated Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Laser‐Based In Situ Diagnostics of Temperature and Material‐Growth Dynamics in Photothermal Laser Nanoprinting of ZnO

open access: yesLaser &Photonics Reviews, EarlyView.
This work elucidates the previously unknown thermal dynamics during sub‐micrometer photothermal laser printing of zinc oxide using a non‐invasive transmission‐based in situ measurement. The elevated temperatures are shown to be highly localized around the laser focal spot, reaching average temperature increases of about 113 K per mW of laser power ...

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

open access: yesMacromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Exocrine Gland Dysfunction in Parkinson's Disease: Pathophysiology, Clinical Manifestations, and Therapeutic Perspectives—A Narrative Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Non‐motor symptoms, especially autonomic dysfunction, are major contributors to disability and decreased quality of life in Parkinson's disease (PD). Despite being common and having a wide range of clinical facets, exocrine gland dysfunction is still not well recognized and managed.

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

open access: yesMetalMat, EarlyView.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...
