Quasi‐Periodic Surface Functionalization by Ultra‐Short Pulsed Laser Processing: Unlocking Superior Heat Transfer in Vapor Chambers

open access: yesAdvanced Functional Materials, EarlyView.
Ultra‐short pulsed laser processing (ULSP) enables scalable, open‐air fabrication of self‐organized, quasi‐periodic micro/nanostructures on copper using 100 µm laser beams, orders of magnitude larger than the resulting surface features. Integrated into ultra‐thin, wick‐free vapor chambers, these laser‐functionalized surfaces dramatically enhance ...

Effect of Intergenerational Trends on Parental Child-Rearing Gender Role Attitudes (PCGAs) in Single-Parent Families: A Relative Mediation

open access: yesBehavioral Sciences
Family structures are diverse, with single-parent families being special. Single-parent families have garnered interest regarding their impact on their children’s development in relation to gender roles and social adaptation.

Approaches for diversity analysis of cultivable and non-cultivable bacteriain real soil

open access: yesPlant, Soil and Environment, 2009
Until recently, investigators had no idea how accurately cultivated microorganisms represented the overall microbial diversity. The cultivation-dependent approach is limited by the fact that the overwhelming majority of microorganisms present in soil ...

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

open access: yesAdvanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux

One Final Sip [PDF]

open access: yesJournal of General Internal Medicine, 2011
The patient was in his 70s but appeared much older. Speaking in broken sentences, he nervously stated that he could not breathe. With each exhalation there were discomforting squeaks and whistles; with each intake of breath his nostrils widened, the muscles on his neck contracted, and his belly moved down towards his torso, making shallow craters in ...

Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

open access: yesAdvanced Photonics Research, EarlyView.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

How Does Parental Early Maladaptive Schema Affect Adolescents’ Social Adaptation? Based on the Perspective of Intergenerational Transmission

open access: yesBehavioral Sciences
An individual’s social adaptation is affected by their early maladaptive schemas. Previous studies have shown that early maladaptive schemas may be intergenerationally transmitted in families.

A distributed end-to-end overload control mechanism for networks of SIP servers. [PDF]

open access: yes, 2012
The Session Initiation Protocol (SIP) is an application-layer control protocol standardized by the IETF for creating, modifying and terminating multimedia sessions. With the increasing use of SIP in large deployments, the current SIP design cannot handle

Nectar-Sipping Birds [PDF]

open access: yesNature, 1922
THE device of Mirafra Assamica to reach the nectar in the flowers of Castanospermum (noted in NATURE of April 15, p. 489) has its parallel among British birds. The blooms of several Asiatic species of rhododendron contain much honey, and many of these are defaced at this season by the great tit (Parus major), the blue tit (P.
