Some Inequalities in 2-inner Product Spaces

, 1999
In this paper we extend some results on the refinement of Cauchy-Buniakowski-Schwarz's inequality and Aćzel's inequality in inner product spaces to 2-inner product ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

POVMs and the Two Theorems of Naimark and Sz.-Nagy

Axioms, 2015
In 1940 Naimark showed that if a set of quantum observables are positive semi-definite and sum to the identity then, on a larger space, they have a joint resolution as commuting projectors. In 1955 Sz.-Nagy showed that any set of observables could be so

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Study of Continuous Corrosion on ASTM A335 P91 Steel in an Environment of CO2-O2-N2-H2O Derived from the Theoretical Combustion Products of a Mixture of Refining Gases at High Temperatures

Chemical Engineering Transactions, 2018
The current energy production processes go hand in hand with corrosive phenomena; which is the case of combustion process in a refinery, where the presence of compounds such as CO2 and H2O, result in alloys catastrophic carburization and oxidation ...

The Temporal and Spatial Variation of Arthropod Associations Inhabiting Non-Crop Vegetation in a Sisal Crop, Agave sisalana in the Caatinga Biome

Applied Sciences, 2021
Sisal, Agave sisalana Perrine, is cultivated for fiber production, with Brazil being its leading producer. Nowadays, given the increasing interest in organic products, the market for sisal could become an economical alternative for rural areas with low ...

ON VARIATIONAL INEQUALITIES IN SEMI-INNER PRODUCT SPACES

Tamkang Journal of Mathematics, 1993
In this paper, we consider and study the variational inequalities in the setting of semi-inner product spaces. Using the auxiliary principle, we propose and analyze an innovative and novel iterative al- gorithm for finding the approximate solution of variational inequalities. We also discuss the convergence criteria. &
