Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Examples of L^2-Complete and Boundedly-Complete Distributions [PDF]

Completeness and bounded-completeness conditions are used increasingly in econometrics to obtain nonparametric identification in a variety of models from nonparametric instrumental variable regression to non-classical measurement error models.

Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids

Advanced Healthcare Materials, EarlyView.
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...

THE DESIGN OF STANDARD GRAPH FOR TODDLER GROWTH USES NONPARAMETRIC PENALIZED SPLINE REGRESSION

Barekeng
One way to carry out early detection of toddler growth is through the Healthy Way Card (KMS). The KMS used in Indonesia does not describe the growth behavior of toddlers. The KMS used is the standard from the World Health Organization (WHO).

Local Polynomial Fitting and Spatial Price Relationships: Price Transmission in the EU Markets for Pigmeat [PDF]

We apply nonparametric methods to assess price transmission processes within the EU pig markets. We compare results derived from nonparametric regressions with those obtained using alternative nonlinear threshold models.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming

Advanced Materials, EarlyView.
Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

THE RELATIONSHIP BETWEEN FAMILY SUPPORT AND SOCIAL SUPPORT WITH DIET ADHERENCE OF HYPERTENSIVE PATIENTS

Journal of Vocational Nursing
Introduction: Hypertension is an escalating global health issue, with diet playing a critical role in its management by limiting salt and saturated fat intake while increasing the consumption of fruits, vegetables, and fiber.

Nonparametric estimation of simplified vine copula models: comparison of methods

Dependence Modeling, 2017
In the last decade, simplified vine copula models have been an active area of research. They build a high dimensional probability density from the product of marginals densities and bivariate copula densities.
