AIEgen‐Based and Smartphone‐Assisted On‐Site Quantitation of Cystatin C for Monitoring of Chronic Kidney Disease

Aggregate, EarlyView.
By employing new protein‐templated AIEgen Ir@BSA as the phosphorescence signal indicator and papain as the biomolecular recognition element, a straightforward protocol for Cys C quantitation has been developed. On‐site quantitation of Cys C in clinical serum samples has been successfully demonstrated using a smartphone‐based portable phosphorescence ...

Chemical Evolution of Zinc in the Galaxy [PDF]

Publications of the Astronomical Society of Japan, 2009
Abstract The local thermodynamic equilibrium (LTE) abundances of zinc (Zn) of our sample of 35 metal-poor stars were explored in the range of $-$3.0 $<$ [Fe$/$H] $<$ 0.0. Based on a combination of our Zn abundances and those obtained in the literature, the behavior of Zn was investigated in the range of $-$4.2 $&lt ...

Chemical behavior of the Dwarf Irregular Galaxy NGC 6822. Its PN and HII region abundances

, 2009
We aim to derive the chemical behavior of a significant sample of PNe and HII regions in the irregular galaxy NGC 6822 The selected objects are distributed in different zones of the galaxy.

The Impact of Modeling Assumptions in Galactic Chemical Evolution Models [PDF]

, 2016
We use the OMEGA galactic chemical evolution code to investigate how the assumptions used for the treatment of galactic inflows and outflows impact numerical predictions.

Tau Amyloid Corona‐Shelled Nanoparticle‐Based Drug Screening Platform for Discovering Tau Oligomer‐Degrading Drugs

Aggregate, EarlyView.
Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.

The Chemical Evolution of the Milky Way

, 1999
The field of chemical evolution modeling of the Galaxy is experiencing in the last years a phase of high activity and important achievements. There are, however, several open questions which still need to be answered. In this review I summarize what have

STAR FORMATION HISTORY AND CHEMICAL EVOLUTION OF THE SEXTANS DWARF SPHEROIDAL GALAXY [PDF]

, 2009
We present the star formation history (SFH) and chemical evolution of the Sextans dSph galaxy as a function of a galactocentric distance. We derive these from the VI photometry of stars in the 42′ × 28′ field using the SMART model developed by Yuk & Lee ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

Advanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Spatial Variations of Stellar Elemental Abundances in FIRE Simulations of Milky Way-mass Galaxies: Patterns Today Mostly Reflect Those at Formation

The Astrophysical Journal
Spatial patterns of stellar elemental abundances encode rich information about a galaxy’s formation history. We analyze the radial, vertical, and azimuthal variations of metals in stars, both today and at formation, in the FIRE-2 cosmological simulations
