Ammonia-Oxidizing Archaea and Bacteria Differentially Contribute to Ammonia Oxidation in Sediments from Adjacent Waters of Rushan Bay, China

open access: yesFrontiers in Microbiology, 2018
Ammonia oxidation plays a significant role in the nitrogen cycle in marine sediments. Ammonia-oxidizing archaea (AOA) and bacteria (AOB) are the key contributors to ammonia oxidation, and their relative contribution to this process is one of the most ...

Speech Disorder in Anterior Open Bite (AOB): Systematic Review

open access: yesDentika: Dental Journal, 2022
There have been numerous researches showing that articulation disorders and malocclusion are linked. The most prevalent malocclusion in speech or articulation disorders is anterior open bite (AOB). Excessive propulsion of the tongue forward when articulating phonemes causes altered articulation in patients with open bites, as the tongue is in a more ...

2D Abrupt Nano‐Junctions Blending sp–sp2 Bonds on Atomically Precise Heterostructures

open access: yesAdvanced Materials, EarlyView.
A lateral heterostructure between atomically precise sp–sp2$^2$ metalated graphdiyne and sp2$^2$ graphene nanoribbons is realized by on‐surface synthesis and investigated by STM and DFT. The impact of on‐surface synthesis byproducts on covalent junction formation yield is unveiled.

The contributions of ammonia oxidizing bacteria and archaea to nitrification-dependent N2O emission in alkaline and neutral purple soils

open access: yesScientific Reports, 2022
Nitrification is believed to be one of the primary processes of N2O emission in the agroecological system, which is controlled by soil microbes and mainly regulated by soil pH, oxygen content and NH4 + availability.

Electroactive 3D Porous Graphene Foam Impedimetric Biosensor for Ultrasensitive Detection of MCF‐7‐Cells‐Derived Extracellular Vesicles in Human Serum

open access: yesAdvanced Materials Technologies, EarlyView.
A label‐free impedimetric biosensor based on electroactive 3D porous graphene foam enables ultrasensitive and selective detection of CD81 protein and MCF‐7 cell‐derived extracellular vesicles in human serum. Detection limits of 0.048 fg/mL for CD81 and ∼24 EVs/mL are achieved, demonstrating a robust platform for selective, label‐free, and ...

Estimation of anisotropic temperature perturbation statistics of MREA'03 data'', Acoustic - Oceanographic Buoy - AOB [PDF]

open access: yes, 2004
Rep 02/06 - SiPLAB 14/Mar/2006In order to oceanographically map a given area, deterministic models of oceanographic processes have been coupled with statistical interpolation tools, to overcome the sparsity of oceanographic measurements.

Goofy/123Cre lineage tracing differentiates olfactory and vomeronasal neurons from GnRH‐1 and terminal nerve neurons during neuronal migration and reveals additional olfactory placode‐derived cells in the brain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract The olfactory placode (OP) generates a broad array of chemosensory neurons in the nasal region, including olfactory sensory neurons, vomeronasal sensory neurons, neurons of the septal organ, and Grueneberg ganglion. During invagination, the OP also generates migratory neuronal populations, including gonadotropin‐releasing hormone‐1 (GnRH‐1 ...

Brain Cortex Activity in Children With Anterior Open Bite: A Pilot Study

open access: yesFrontiers in Human Neuroscience, 2020
Anterior open bite (AOB) is related to functional alterations of the stomatognathic system. There are no studies concerning brain activation of the cortex comparing children with and without AOB during rest and activities such as deglutition and ...
