Frontiers of Bright CEP‐Stable Broadband Infrared Sources

open access: yesLaser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Observation of quantum interference in the plasmonic Hong-Ou-Mandel effect

open access: yes, 2014
We report direct evidence of the bosonic nature of surface plasmon polaritons (SPPs) in a scattering-based beamsplitter. A parametric down-conversion source is used to produce two indistinguishable photons, each of which is converted into a SPP on a ...

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

open access: yesSustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

Demonstration of local expansion toward large-scale entangled webs

open access: yes, 2010
We demonstrate an optical gate that increases the size of polarization-based W states by accessing only one of the qubits. Using this gate, we have generated three-photon and four-photon W states with fidelities $0.836\pm 0.042 $ and $0.784\pm 0.028 ...

Phase, glass formation and the properties of BaO–Bi[2]O[3]–B[2]O[3] glasses [PDF]

open access: yes, 2013
Information on phase and glass formation in bismuth-borate systems as a basis for obtaining lead-free low-melting glasses with wide ranging physical and optical properties is generalized.

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...

Boosting the optical, physical, and gamma-ray attenuation capabilities of barium borate glasses through the addition of Y2O3 and PbO2

open access: yesOpen Ceramics
The objective of the current study is to develop a new glass series for hybrid uses in optical and γ-ray protective applications. The mentioned glass series is composed of high-purity oxides according to the chemical formula of (10+x)PbO2+23BaO+10CaO+(55-

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Investigating Technology and Raw Materials Source of the Archaic and Classical Architectural Terracottas From the Athenaion in Castro (Apulia, Italy)

open access: yesArchaeometry, Volume 68, Issue 3, Page 512-526, June 2026.
ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...
