Second-Order Differential Equation with Indefinite and Repulsive Singularities

open access: yesBulletin of the Malaysian Mathematical Sciences Society, 2023
This paper concerns a second-order differential equation with indefinite and repulsive singularities. It is the first time to study differential equation containing both indefinite and repulsive singularities simultaneously. A set of sufficient conditions are obtained for the existence of positive periodic solutions.

Subject Bare Singulars in Brazilian Portuguese and Information Structure

open access: yesJournal of Portuguese Linguistics, 2015
This paper contributes to the debate on the semantics of bare singular nouns (BSNs) in Brazilian Portuguese by looking at the restrictions on their use as subjects. After a reassessment of the literature (e.g., Schmitt & Munn 1999, Müller 2000, Pires

On Indefinite Singular Generics

open access: yes, 2023
Consider a simple statement like 'A dog has four legs', which, under a generic reading, is an example of an Indefinite Singular (IS) generic. Different varieties of generics are differentiated by their subject nominal type; for instance, English has both the indefinite singular and bare plural (BP) generic (e.g. 'Dogs have four legs').

Numerical indefinite integration of functions with singularities [PDF]

open access: yesMathematics of Computation, 2000
We derive an indefinite quadrature formula, based on a theorem of Ganelius, for H p H^p functions, for p > 1 p>1 , over the interval ( − 1 , 1 ) (-1,1) .

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Cross-linguistic variation in the expression of ignorance

open access: yesIsogloss
This article examines the properties of epistemic indefinites (EIs) when pluralized, focusing on the following puzzle: while ignorance is expressed by both singular and plural EIs in a number of languages, e.g.

On the Generic Use of Indefinite Singulars [PDF]

open access: yesJournal of Semantics, 2001
The distribution of indefinite singular generics is much more restricted than that of bare plural generics. The former, unlike the latter, seem to require that the property predicated of their subject be, in some sense, definitional'. Moreover, the two constructions exhibit different scopal behaviour, and differ in their felicity in conjunctions ...

Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

open access: yesAdvanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Analyzing individual rent price ratios in eastern German agricultural land markets: A GAMLSS approach

open access: yesAgribusiness, EarlyView.
Abstract This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results.
