Temperature-Dependence of Magnetically-Active Charge Excitations in Magnetite across the Verwey Transition [PDF]

, 2015
We have studied the electronic structure of bulk single crystals and epitaxial films of magnetite Fe$_3$O$_4$. Fe $2p$ core-level spectra show clear differences between hard x-ray (HAX-) and soft x-ray (SX-) photoemission spectroscopy (PES), indicative ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

The Generalized-Method in Taguchi Experiments

, 1997
In the presence of variability control factors in Taguchi experiments, then the original L-method (Logothetis, 1990) is liable to lead to wrong transformations. We propose a generalization of the Lß-method which should lead to correct transformations, even if there is a variability control factor which also in uences the mean.

The Application of Taguchi-WSM, Taguchi-WPM and Taguchi-WASPAS Multicriteria Methods to Optimize Downtime in a Production Process

IJIEM - Indonesian Journal of Industrial Engineering and Management, 2022
In the industrial transformation of animal feed for chickens, downtime analysis is a crucial part of the plant's operations. Unfortunately, the literature on downtime analysis has a serious shortcoming; it fails to link downtime with Taguchi method’s optimization and ranking. To correct this deficiency, this paper proposes a new method that couples the
