Unique thermal behavior of sphingomyelin species with nonhydroxy and 2-hydroxy very-long-chain (C28-C32) PUFAs[S]

open access: yesJournal of Lipid Research, 2013
In rat germ cells and spermatozoa, sphingomyelin (SM) contains molecular species with nonhydroxy (n) and 2-hydroxy (h) very-long-chain polyunsaturated fatty acids (V), the most abundant being SMs with (n- and h-) 28:4n-6, 30:5n-6, and 32:5n-6 as acyl ...

A Fuzzy Risk Assessment Approach Based on Z‐Numbers for Enhancing Safety and Human‐Robot Collaboration in Automotive Sector

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel risk assessment approach that integrates the fuzzy set theory and Z‐numbers with multicriteria decision‐making techniques (Delphi, decision‐making trial and evaluation laboratory, analytic network process, and VIseKriterijumska Optimizacija I Kompromisno Resenje) to manage uncertainty and prioritize human–robot collaboration risks. A real‐world

Metcalfe's law and log-period power laws in the cryptocurrencies market

open access: yesEconomics: Journal Articles, 2019
In this paper the authors investigate the statistical properties of some cryptocurrencies by using three layers of analysis: alpha-stable distributions, Metcalfe’s law and the bubble behaviour through the LPPL modelling.

General Split Helicity Gluon Tree Amplitudes in Open Twistor String Theory

open access: yes, 2010
We evaluate all split helicity gluon tree amplitudes in open twistor string theory. We show that these amplitudes satisfy the BCFW recurrence relations restricted to the split helicity case and, hence, that these amplitudes agree with those of gauge ...

Supply Chain Configuration Adaptations of Highly‐Polluting Firms in Response to Shocks From Environmental Pressures: Case for Centralization or Diversification?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how environmental regulatory shocks affect the supply chain configuration of highly polluting firms, a relatively understudied area in the sustainable operations literature. Using a panel dataset of Chinese A‐share listed firms from 2009 to 2022, we employ a Difference‐in‐Differences (DID) design to examine the causal ...

Modulation of the Acidity of HY, HBETA, and HZSM‐5 Zeolites by Lanthanum Incorporation for Selective Gasoline Desulfurization in the FCC Riser

open access: yesChemCatChem, EarlyView.
Desulfurization in the FCC riser is achieved by modifying zeolite catalysts with La3+ ions, promoting H2S formation from thiophenic compounds while suppressing secondary reactions. This approach enhances gasoline quality by increasing selectivity for H2S and enabling efficient condensation and alkylation, supporting cleaner fuel production and ...
