A Lensed Arc in the Low Redshift Cluster Abell 2124
, 1998 We report the discovery of an arc-like object 27" from the center of the cD galaxy in the redshift $z=0.066$ cluster A2124. Observations with the Keck II telescope reveal that the object is a background galaxy at $z=0.573$, apparently lensed into an arc ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Certain Extremal Problems on a Classical Family of Univalent Functions
MathematicsConsider the collection A of analytic functions f defined within the open unit disk D, subject to the conditions f(0)=0 and f′(0)=1. For the parameter λ∈[0,1), define the subclass R(λ) as follows:R(λ):=f∈A:Ref′(z)>λ,z∈D.

On the Maximum Arc Length of Monotonic Functions [PDF]
The American Mathematical Monthly, 2014 We revisit a problem solved in 1963 by Zaanen & Luxemburg in this MONTHLY: What is the largest possible length of the graph of a monotonic function on an interval? Is there such a function that attains this length? This is an interesting and intriguing problem with a somewhat surprising answer that should be of interest to a broad spectrum of ...

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the
