Evolution of magnetic surfboards and spin glass behavior in (FeGa)TiO.

The unusual anisotropy of the spin glass (SG) transition in the pseudobrookite system FeTiOhas been interpreted as arising from an induced, van der Waals-like, interaction among magnetic clusters. Here we present susceptibility (χ) and specific heat data (C) for FeTiOdiluted with non-magnetic Ga, (FeGa)TiO, for disorder parameterp= 0, 0.11, and 0.

Magnetoquantum oscillations in the specific heat of a topological Kondo insulator.

Surprisingly, magnetoquantum oscillations (MQOs) characteristic of a metal with a Fermi surface have been observed in measurements of the topological Kondo insulator SmB. As these MQO have only been observed in measurements of magnetic torque (dHvA) and not in measurements of magnetoresistance (SdH), a debate has arisen as to whether the MQO are an extrinsic effect arising from rare-earth impurities, defects, and/or aluminum inclusions or an intrinsic effect revealing the existence of charge-neutral excitations. We report here the first observation of MQO in the low-temperature specific heat of SmB.

In situ Tissue Regeneration in the Cornea from Bench to Bedside.

Corneal blindness accounts for 5.1% of visual deficiency and is the fourth leading cause of blindness globally. An additional 1.

Extremely Weakly Interacting ΔS_{z}=0 and ΔS_{z}=1 Excitations and Evidence for Fractional Quantization in a Magnetization Plateau: CeSb.

The plateau at 1/3 of the saturation magnetization M_{s} in the metamagnet CeSb is accompanied by a state of ferromagnetic layers of spins in an up-up-down sequence. We measured M and the specific heat C in the plateau, spin wave analyses of which reveal two distinct branches of excitations. Those with ΔS_{z}=1 as measured by M, coexist with a much larger population of ΔS_{z}=0 excitations measured by C but invisible to M.

Usability and acceptability of a multimodal respiratory rate and pulse oximeter device in case management of children with symptoms of pneumonia: A cross-sectional study in Ethiopia.

Aim: Pneumonia is the leading infectious cause of death among children under five globally. Many pneumonia deaths result from inappropriate treatment due to misdiagnosis of signs and symptoms. This study aims to identify whether health extension workers (HEWs) in Ethiopia, using an automated multimodal device (Masimo Rad-G), adhere to required guidelines while assessing and classifying under five children with cough or difficulty breathing and to understand device acceptability.
