Occurrence and monthly dynamics of female Phlebotomine sandfly species from Kousseri Visceral Leishmaniasis endemic focus in northern Cameroon [PDF]

African Invertebrates
Leishmaniasis, an anthropozoonotic infection transmitted to humans and animals through female sandfly bite, is endemic in the far north region of Cameroon, which currently lacks a control programme.

Statistical inference for Vasicek-type model driven by Hermite processes [PDF]

, 2018
Let $Z$ denote a Hermite process of order $q \geq 1$ and self-similarity parameter $H \in (\frac{1}{2}, 1)$. This process is $H$-self-similar, has stationary increments and exhibits long-range dependence.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations

Advanced Functional Materials, EarlyView.
β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

On variable Wiener index

Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 2003
A variable Wiener index W-nu, applicable only to acyclic structures, is defined as Sigma [n(1)(e) n(2)(e)](lambda). For the optimal exponent, that value of lambda should be selected which gives the smallest standard error of estimate, s, in the structure-property-modeling. As a test case, the structure-boiling point modeling of isomeric octanes is used.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Floristic Diversity, Indicator and Suitable Species for Andean Livestock in the Sillapata Micro-Watershed, Acopalca

International Journal of Plant Biology
Andean grassland ecosystems in Peru are characterized by diverse plant species adapted to environmental factors including weather, soil type, elevation, slope orientation, and soil moisture. This study evaluated the floristic composition, alpha diversity,

Antimicrobial Efficacy of a Taurolidine‐Based Antimicrobial Compound on Contaminated Surfaces Simulated in a Standardized 4‐Field Test

Advanced Healthcare Materials, EarlyView.
As implantable medical devices become indispensable to modern medicine, a silent threat grows alongside them: device‐associated infections. Despite decades of antibiotic innovation, infection rates keep climbing, costing lives and billions in healthcare expenses.

Ground beetle (Coleoptera, Carabidae) diversity in Finnish arable land

Agricultural and Food Science, 2008
Carabid data compiled from six independent studies, consisting of 97 799 individuals trapped by pitfalls from Finnish agricultural fields and identified to 111 species were analyzed. Shannon-Wiener H' diversity index was typically around 2.5 and expected

The center of mass of the ISE and the Wiener index of trees

, 2003
We derive the distribution of the center of mass $S$ of the integrated superBrownian excursion (ISE) {from} the asymptotic distribution of the Wiener index for simple trees. Equivalently, this is the distribution of the integral of a Brownian snake.
