A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage

Journal of Fish Biology, EarlyView.
Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.

Expectations for Families to Care for Older Adults in the United States: Rapid Scoping Review 2011–2023

Journal of Family Theory &Review, EarlyView.
ABSTRACT As the population ages and families become increasingly diverse, more work is needed to understand expectations for families to care for older adults. In this review, we discuss the theoretical frameworks and conceptualizations used to study care expectations, summarize overarching findings about theories of care expectations and corresponding

Additive Structure of Sparse-Digit Fractal Sets: Sumsets, Difference Sets, and Dimension Jumps

Mathematics
We study the additive and fractal structure of digit-restricted subsets of the unit interval where AD=∑n=1∞anb−n:an∈D⊆{0,…,b−1},|D|≥2, defined by allowing only digits from D in base-b expansions.

Local fractional homotopy analysis method for solving non-differentiable problems on Cantor sets

Advances in Difference Equations, 2019
In this paper, we present a semi-analytic method called the local fractional homotopy analysis method (LFHAM) for solving differential equations involving local fractional derivatives based on the local fractional calculus and the homotopy analysis ...

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Local fractional variational iteration algorithm II for non-homogeneous model associated with the non-differentiable heat flow

Advances in Mechanical Engineering, 2015
In this article, we begin with the non-homogeneous model for the non-differentiable heat flow, which is described using the local fractional vector calculus, from the first law of thermodynamics in fractal media point view. We employ the local fractional

Associations between apathy and global cognition in a 5‐year follow‐up of individuals with Alzheimer's disease

Journal of Neuropsychology, EarlyView.
Abstract Apathy is a common neuropsychiatric symptom in Alzheimer's disease (AD) associated with cognitive and functional impairment. Longitudinal studies have examined the associations between apathy and cognition in AD and other dementias, but more information is needed to understand whether the relationships are consistent longitudinally, and ...

Signal Processing for Nondifferentiable Data Defined on Cantor Sets: A Local Fractional Fourier Series Approach

Advances in Mathematical Physics, 2014
From the signal processing point of view, the nondifferentiable data defined on the Cantor sets are investigated in this paper. The local fractional Fourier series is used to process the signals, which are the local fractional continuous functions.

Genus of a Cantor Set

Rocky Mountain Journal of Mathematics, 2005
A defining sequence for a Cantor set, \(X\), in 3-space, is a sequence of compact 3-manifolds, \((M_i)\) with boundary, each consisting of disjoint cubes with handles, \(M_{i+1}\subset\text{Int}\,M_i\) and \(X=\bigcap M_i\). If \(A\subset X\), \(g_A(X;(M_i))\) is the maximum genus of those components of the \(M_i\) which intersect \(A\).

Harnessing Human Mobility Data for Applied Economic Research: Current Knowledge, Challenges, and Emerging Opportunities

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper reviews how large‐scale mobility data can enhance economic analyses, highlighting its contributions to understanding travel behavior, labor markets, social interactions, and health outcomes. We discuss its advantages over traditional mobility data sources, which include real‐time location information and fine spatial resolution ...
