Intertwined Topological Phases in TaAs2 Nanowires with Giant Magnetoresistance and Quantum Coherent Surface Transport

Advanced Materials, EarlyView.
Synthesis of topological semimetal TaAs2 nanowires in situ encapsulated with a thin SiO2 shell unravel a richness of intertwined topological phases manifested by their magnetotransport features: A near‐room‐temperature metal‐to‐insulator transition, strong expressions of topologically nontrivial surface transport, giant magnetoresistance with direction‐

Anterior open bite and oral port constriction.

The Angle orthodontist, 1976
Intraoral air pressure and rate of oral airflow were measured simultaneously during fricative sound production in ten subjects with anterior open bite and ten subjects with normal occlusion and speech. From these measurements the area of oral port constriction was calculated and the values compared within and between the two groups.

Anterior open bite with temporomandibular disorders treated with intermaxillary traction using skeletal anchorage system. [PDF]

, 2012
OBJECTIVES: The anterior open bite with temporomandibular disorders (TMD) is one of the most challenging cases both orthodontically and surgically. We introduce an intermaxillary traction treatment for patients with anterior open bite and TMD using a ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Engineering Cellular Self‐Adhesions Inside 3D Printed Micro‐Arches to Enhance Cell:Biomaterial Attachment

Advanced Materials, EarlyView.
Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

Once bitten, twice shy: A modeling framework for incorporating heterogeneous mosquito biting into transmission models [PDF]

arXiv
The potential for outbreaks of mosquito-borne disease is linked to the frequency at which mosquitoes feed on blood, also known as the biting rate. But standard models of mosquito-borne disease transmission inherently assume that mosquitoes bite only once per reproductive cycle, an assumption commonly violated in nature. Drivers of multiple biting, like

Efficient Convergent Maximum Likelihood Decoding on Tail-Biting Trellises [PDF]

arXiv, 2006
An algorithm for exact maximum likelihood(ML) decoding on tail-biting trellises is presented, which exhibits very good average case behavior. An approximate variant is proposed, whose simulated performance is observed to be virtually indistinguishable from the exact one at all values of signal to noise ratio, and which effectively performs computations

Impairment of the oral stereognosis in the partial anterior open bite [PDF]

, 2006
The study was performed in 20 children with partial anterior open bite and in 20 children of a control group. Stereognosis was evaluated on the basis of correct recognition responses to silicone pieces of the different shapes.
