Effect of land use on mayfly assemblages structure in Neotropical headwater streams

Anais da Academia Brasileira de Ciências, 2014
The aim of this study was to test the effect of agricultural and forestry land use on the structure of mayfly assemblages in low-order streams. Twenty-nine headwater streams were investigated in the state of São Paulo.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Word Forms Are Structured for Efficient Use [PDF]

Cognitive Science, 2018
AbstractZipf famously stated that, if natural language lexicons are structured for efficient communication, the words that are used the most frequently should require the least effort. This observation explains the famous finding that the most frequent words in a language tend to be short.

Gender differences in symptom structure of adolescent problematic internet use: A network analysis

Child and Adolescent Psychiatry and Mental Health, 2023
Background Gender differences in problematic Internet use (PIU) have long been discussed. However, whether and how female and male adolescents differ in central symptoms and symptom associations are not fully understood.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Using PageRank to Characterize Web Structure [PDF]

Internet Mathematics, 2002
Recent work on modeling the Web graph has dwelt on capturing the degree distributions observed on the Web. Pointing out that this represents a heavy reliance on "local" properties of the Web graph, we study the distribution of PageRank values (used in the Google search engine) on the Web.

Agricultural Land-Use Structure Across Hierarchical Classification Levels in Kosovo

Land
Fine-grain heterogeneity in agricultural landscapes is often obscured by coarse land-use classification schemes. This study provides a structural characterization of agricultural land use in selected sites within the Dukagjini and Kosova Plains of Kosovo

Terrain Gradient Effect and Spatial Structure Characteristics of Land Use in Dashanbao Area

Shuitu baochi tongbao, 2022
[Objective] The influence of topographical factors on land use pattern and spatial structure characteristics was explored in order to provide a scientific reference basis for the planning and decision-making of land development and utilization in ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Image Stitching Using Structure Deformation [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008
The aim of this paper is to achieve seamless image stitching without producing visual artifact caused by severe intensity discrepancy and structure misalignment, given that the input images are roughly aligned or globally registered. Our new approach is based on structure deformation and propagation for achieving overall consistency in image structure ...
