Ascent sequences and the binomial convolution of Catalan numbers [PDF]

open access: yes, 2014
In this paper, we consider two sets of pattern-avoiding ascent sequences: those avoiding both 201 and 210 and those avoiding 0021. In each case we show that the number of such ascent sequences is given by the binomial convolution of the Catalan numbers ...

Axial charges of hyperons and charmed baryons using $N_f=2+1+1$ twisted mass fermions

open access: yes, 2016
The axial couplings of the low lying baryons are evaluated using a total of five ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed using the Iwasaki gauge action and two degenerate flavors of light quarks ...

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Spectral Estimates, Contractions and Hypercontractivity

open access: yes, 2018
Sharp comparison theorems are derived for all eigenvalues of the (weighted) Laplacian, for various classes of weighted-manifolds (i.e. Riemannian manifolds endowed with a smooth positive density).

Manufacturing Continuous Fiber‐Reinforced Printing Filaments: Development of a Post‐Consolidation Unit

open access: yesAdvanced Engineering Materials, EarlyView.
A novel, temperature‐controlled post‐consolidation unit is developed to test its potential to improve the melt impregnation process used to manufacture continuous fiber‐reinforced filaments for additive manufacturing of high‐performance thermoplastics.

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

The contribution of the fine sediment fraction to the Fluffy Layer Suspended Matter (FLSM)

open access: yesOceanologia, 2002
Fluffy Layer Suspended Matter (FLSM) is a layer of fairlyconcentrated suspended matter resting on the sea floor. Itspassage to the depositional basins in the Pomeranian Bay -Arkona Deep System of the Baltic Sea is estimated to takearound six months.

Effect of post harvest application of chemicals and different packaging materials on shelf-life of banana (Musa spp) cv Robusta

open access: yesThe Indian Journal of Agricultural Sciences, 2015
An experiment was conducted in Department of Horticulture (Fruit and Fruit Technology), Bihar Agricultural College, Sabour, Bihar during 2010-11 to delay ripening and extend shelf-life of banana (Musa paradisiaca L.) fruit.

The Effects of Auditor Tenure on Fraud and Its Detection [PDF]

open access: yes, 2019
We examine the strategic effects of auditor tenure on the auditor's testing strategy and the manager's inclination to commit fraud. Most empirical studies conclude that longer tenure improves audit quality.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
