Deriving the Metallicity Distribution Function of Galactic Systems [PDF]

, 2003
The chemical evolution of the Milky Way is investigated using a dual-phase metal-enriched infall model in which primordial gas fuels the earliest epoch of star formation, followed by the ongoing formation of stars from newly accreted gas.

MDFS - MultiDimensional Feature Selection

, 2018
Identification of informative variables in an information system is often performed using simple one-dimensional filtering procedures that discard information about interactions between variables. Such approach may result in removing some relevant variables from consideration.

Effects of chemical and biological warfare agent decontaminants on trace survival: Impact on fingermarks deposited on paper

Journal of Forensic Sciences, EarlyView.
Abstract Chemical and biological events present a challenging environment for forensic scientists to perform their work. This research is the follow‐up of the previous article that investigated the impact of decontaminants on fingermarks deposited on glass.

The importance of biogenic carbon storage in the greenhouse gas footprint of medium density fiberboard from poplar wood and bagasse

Cleaner Environmental Systems, 2021
Carbon storage in long-lived bio-based products is typically ignored or accounted for in a simplistic way in greenhouse gas (GHG) footprint calculations.

Induction of Colonic Aberrant Crypts in Mice by Feeding Apparent N-Nitroso Compounds Derived From Hot Dogs [PDF]

, 2012
Nitrite-preserved meats (e.g., hot dogs) may help cause colon cancer because they contain N-nitroso compounds. We tested whether purified hot-dog-derived total apparent N-nitroso compounds (ANC) could induce colonic aberrant crypts, which are putative ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Investigation of the effects of heat treatment on medium density fiberboard (MDF)

Turkish Journal of Forestry
In particular, materials such as medium density fiberboard (MDF) have advantages such as high strength, homogeneous structure and easy processability, but disadvantages such as sensitivity to water and formaldehyde emission.

Confinement control by optical lattices

, 2004
It is shown that the interplay of a confining potential with a periodic potential leads for free particles to states spatially confined on a fraction of the total extension of the system.

Uncovering the Process of Sexual Segregation: Male Early‐Life Individual Tactics Shape Its Onset and Affect Phenotypic Quality in a Large Mammal

Integrative Zoology, EarlyView.
Early‐life traits significantly influence sexual segregation patterns and phenotypic quality in male fallow deer. Males in better condition and those more risk‐prone left natal groups earlier with fewer returns to natal groups. However, males with frequent excursions back to natal groups compensated for initial body condition disadvantages.
