Rational Control of Antibody Orientation for Enhancing Sensitivity and Specificity in Lateral Flow Immunoassays With Clinical Validation

open access: yesAdvanced Healthcare Materials, EarlyView.
Systematic investigation of antibody orientation strategies in lateral flow immunoassays reveals that a para‐substituted (aminomethyl)phenylboronic acid mediated probe (P‐6) combined with a biotin‐streptavidin test‐line modification achieves a synergistic 14‐ to 19‐fold sensitivity gain over conventional conjugation. Furthermore, multiplexed detection,

High palaeolatitude (Hodh, Mauritania) recovery of graptolite faunas after the Hirnantian (end Ordovician) extinction event [PDF]

open access: yes
Marine shales directly overlying lower Hirnantian (uppermost Ordovician) glacially related sediments in Mauritania (North-West Africa) have produced a rich graptolite fauna spanning the Ordovician-Silurian boundary in an area of high palaeolatitude.

Stochastic two-species mutualism model with jumps

open access: yesModern Stochastics: Theory and Applications, 2020
The existence and uniqueness are proved for the global positive solution to the system of stochastic differential equations describing a two-species mutualism model disturbed by the white noise, the centered and non-centered Poisson noises.

Identification of local extinction and prediction of reignition in a spark-ignited sparse spray flame using data mining [PDF]

open access: yes, 2018
Direct Numerical Simulations (DNS) of droplet fields which are ignited using a spark are investigated to deduce any behaviour that distinguishes between the cases where successful flame propagation occurs and where a flame ignites but subsequently ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Are AMPA Receptor Positive Allosteric Modulators Potential Pharmacotherapeutics for Addiction?

open access: yesPharmaceuticals, 2013
Positive allosteric modulators (PAMs) of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are a diverse class of compounds that increase fast excitatory transmission in the brain.

High levels of species' extirpation in an urban environment—A case study from Berlin, Germany, covering 1700–2023

open access: yesEcology and Evolution
Species loss is highly scale‐dependent, following the species–area relationship. We analysed spatio‐temporal patterns of species' extirpation on a multitaxonomic level using Berlin, the capital city of Germany.

Extinction and viruses

open access: yesBiosystems, 1993
The micropaleontological record of deep-sea sediments is demonstrably continuous through time and, therefore, it can be used to study in detail the evolutionary process. Several taxa, including Coccolithophorida, planktic Foraminifera, Radiolaria, and diatoms, are abundantly represented.

Humidity modifies species‐specific and age‐dependent heat stress effects in an insect host‐parasitoid interaction

open access: yesEcology and Evolution
Climate change is projected to increase the frequency and intensity of extreme heat events, and may increase humidity levels, leading to coupled thermal and hydric stress.
