Test module filtrations for unit $F$-modules

2015

We extend the notion of test module filtration introduced by Blickle for Cartier modules. We then show that this naturally defines a filtration on unit $F$-modules and prove that this filtration coincides with the notion of $V$-filtration introduced by Stadnik in the cases where he proved existence of his filtration. We also show that these filtrations do not coincide in general. Moreover, we show that for a smooth morphism $f: X \to Y$ test modules are preserved under $f^!$. We also give examples to show that this is not the case if $f$ is finite flat and tamely ramified along a smooth divisor.

A criterion for extending morphisms from open subsets of smooth fibrations of algebraic varieties

2021

Abstract Given a smooth morphism Y → S and a proper morphism P → S of algebraic varieties we give a sufficient condition for extending an S-morphism U → P , where U is an open subset of Y, to an S-morphism Y → P , analogous to Zariski's main theorem.

Boundedness and spectral invariance for standard pseudodifferential operators on anisotropically weighted LP-Sobolev spaces

1990

It is shown that pseudodifferential operators with symbols in the standard classes S ρ,δ m (ℝn) define bounded maps between large classes of weighted LP-Sobolev spaces where the growth of the weight does not have to be isotropic. Moreover, the spectrum is independent of the choice of the space.

Too special to be duped: Need for uniqueness motivates conspiracy beliefs

2017

Adding to the growing literature on the antecedents of conspiracy beliefs, this paper argues that a small part in motivating the endorsement of such seemingly irrational beliefs is the desire to stick out from the crowd, the need for uniqueness. Across three studies, we establish a modest but robust association between the self-attributed need for uniqueness and a general conspirational mindset (conspiracy mentality) as well as the endorsement of specific conspiracy beliefs. Following up on previous findings that people high in need for uniqueness resist majority and yield to minority influence, Study 3 experimentally shows that a fictitious conspiracy theory received more support by people…

Individual variance in responsiveness to early computerized mathematics intervention

2015

Abstract We examined the effects of short, intensive computerized intervention in early number skills for kindergarteners with poor addition skills (below 1.5 SD ). The mathematical content of the software was hierarchically organized, starting from one-to-one correspondence, comparing and ordering, and proceeding via number concept and counting to basic addition. The results showed positive within-group effects for basic addition (Wilcoxon ES ( r ) = .59), verbal counting (.56), and the Number Sets Test (.45; see Geary, Bailey, & Hoard, 2009 ). The effects remained stable over a 9-week follow-up period. However, there was no significant between-group difference in terms of gain scores as c…

La prestación de maternidad en los supuestos de gestación subrogada

2018

Surrogate pregnancy, as a technique of assisted reproduction prohibited by Spanish law, raises a number of legal questions than, in certain cases, trascend of the Civil Law. Specifically, it has been discussed about de possibility that de person or persons consigner in the gestation contract substitution have access to the provision for maternity benefit. Recently, the Spanish Supreme Court has responded to this issue in the sense of recognizing the right to the provision for maternity benefit to the father or mother ?in fact?, efecttively, develop own parental powers.

Interfacial fracture toughness of universal adhesive systems treated with an antioxidant

2017

Background Secondary caries, degradation of the dentin-resin interface and fracture of the restoration are the most common forms of failure. The aim of this study was to assess the interfacial fracture toughness of three different adhesive approaches and to compare their fracture toughness after surface treatment with antioxidant. Material and methods Seventy two dentin blocks with 3×4mm dimension and 3mm thickness were prepared and attached to precured 3×4×12mm composite blocks from both sides. Six adhesive groups (N=12), All-bond universal, Scotchbond universal and Clearfil SE bond with or without antioxidant treatment (Sodium Ascorbate 10% )were applied to dentin surfaces, a 160µ polyeth…

Effect of antioxidants on the shear bond strength of composite resin to enamel following extra-coronal bleaching

2019

Background Recently patients need faster treatments, and delaying restoration is not possible following bleaching treatment. The purpose of this study was to determine the effect of antioxidants, namely 10% sodium ascorbate, 10% alpha-tocopherol, 10% green tea and 10% Aloe vera extract on the shear bond strength of composite resin to enamel following extra-coronal bleaching using 40% hydrogen peroxide. Material and Methods Seventy premolars were randomly assigned into 7 groups of 10 each. Group 1: bleaching treatment and no antioxidants application. Group 2: composite was built-up immediately after bleaching. Group 3: bleached specimens received composite build-up delayed by 2 weeks. Group …

Structure, stability, and fragmentation of sodium bis(2-ethylhexyl)sulfosuccinate negatively charged aggregates in vacuo by MD simulations.

2014

Negatively charged supramolecular aggregates formed in vacuo by n bis(2-ethylhexyl)sulfosuccinate (AOT(-)) anions and n + n(c) sodium counterions (i.e., [AOT(n) Na(n+nc)](nc)) have been investigated by molecular dynamics (MD) simulations for n = 1 to 20 and n(c) = -1 to -5. By comparing the maximum excess charge values of negatively and positively charged AOTNa aggregates, it is found that the charge storage capability is higher for the latter systems, the difference decreasing as the aggregation number increases. Statistical analysis of physical properties like gyration radii and moment of inertia tensors of aggregates provides detailed information on their structural properties. Even for …
