This study examined how speech babble noise differentially affected the auditory P3 responses and the associated neural oscillatory activities for consonant and vowel discrimination in relation to segmental- and sentence-level speech perception in noise. The data were collected from 16 normal-hearing participants in a double-oddball paradigm that contained a consonant (/ba/ to /da/) and vowel (/ba/ to /bu/) change in quiet and noise (speech-babble background at a -3 dB signal-to-noise ratio) conditions. Time-frequency analysis was applied to obtain inter-trial phase coherence (ITPC) and event-related spectral perturbation (ERSP) measures in delta, theta, and alpha frequency bands for the P3 response...

Voltage-dependent calcium channels (VDCCs) play an essential role in regulating cerebral artery diameter and it is widely appreciated that the L-type VDCC, CaV1.2, encoded by the CACNA1C gene, is a principal Ca(2+) entry pathway in vascular myocytes. However, electrophysiological studies using 10 mM extracellular barium ([Ba(2+)]o) as a charge carrier have shown that ~20% of VDCC currents in cerebral artery myocytes are insensitive to 1,4-dihydropyridine (1,4-DHP) L-type VDDC inhibitors such as nifedipine. Here, we investigated the hypothesis that the concentration of extracellular divalent cations can influence nifedipine inhibition of VDCC currents...

Landscape change and altered host abundance are major drivers of zoonotic pathogen emergence. Conservation and biodiversity management of landscapes and vertebrate communities can have secondary effects on vector-borne pathogen transmission that are important to assess. Here we review the potential implications of these activities on the risk of Lyme borreliosis in the United Kingdom. Conservation management activities include woodland expansion, management and restoration, deer management, urban greening and the release and culling of non-native species...

Finite element simulation of facial mimics provides objective indicators about soft tissue functions for improving diagnosis, treatment and follow-up of facial disorders. There is a lack of in vivo experimental data for model development and validation. In this study, the contribution of the paired Zygomaticus Major (ZM) muscle contraction on the facial mimics was investigated using in vivo experimental data derived from MRI. Maximal relative differences of 7.7% and 37% were noted between MRI-based measurements and numerical outcomes for ZM and skin deformation behaviors respectively...

We present the optical investigation of a novel back-contacted architecture for solar cells based on a thin barium (di)silicide (BaSi<sub>2</sub>) absorber. First, through the analysis of absorption limits of different semiconducting materials, we show the potential of BaSi<sub>2</sub> for photovoltaic applications. Then, the proposed back contacted BaSi<sub>2</sub> solar cell design is investigated and optimized. An implied photocurrent density of 40.3 mA/cm<sup>2</sup> in a 1-μm thick absorber was achieved, paving the way for novel BaSi<sub>2</sub>-based thin-film solar cells...

A key challenge in photovoltaics today is to develop cell technologies with both higher efficiencies and lower fabrication costs than incumbent crystalline silicon (c-Si) single-junction cells. While tandem cells have higher efficiencies than c-Si alone, it is generally challenging to find a low-cost, high-performance material to pair with c-Si. However, the recent emergence of 22% efficient perovskite photovoltaics has created a tremendous opportunity for high-performance, low-cost perovskite / crystalline silicon tandem photovoltaic cells...

In this study, an acidic biochar and a neutral biochar were applied at 5 wt% into two soils for an 11-month incubation experiment. One Ferrosol soil (Ba) was slightly acidic with low organic matter and the other Dermosol soil (Mt) was slightly alkaline with high organic matter. The acidic (pH = 3.25) wood shaving (WS) biochar had no marked impact on nutrient levels, cation exchange capacity (CEC), pH and acid neutralization capacity (ANC) of either soil. By contrast, the neutral (pH = 7.00) chicken litter (CL) biochar significantly increased major soluble nutrients, pH, ANC of soil Ba...

Organisms possess a range of thermoregulatory strategies that may vary in response to sickness, thereby driving important life-history consequences. Because the immune system is vital to maintaining organism function, understanding the suite of immune responses to infection indicates basic costs and benefits of physiological strategies. Here, we assessed consequences of thermoregulation and seasonality on immune function in both immunologically stimulated and nonstimulated gopher tortoises (Gopherus polyphemus)...

The silicon route to improve the ultraviolet (UV) transparency in phosphate glasses is investigated, and further exploited to enhance the UV type B (280-320 nm) emission of gadolinium(III) relevant for biomedical applications. The glasses were synthesized with a barium-phosphate composition by melt-quenching in ambient atmosphere, and the optical properties investigated by optical absorption and photoluminescence (PL) spectroscopy including emission decay kinetics. An improvement in the UV transparency was gradually developed for the glasses melted merely with increasing amounts of Si powder...

The composite of tungsten-doped SnO2 and reduced graphene oxide was synthesized through a simple one-pot hydrothermal method. According to the structural characterization of the composite, tungsten ions were doped in the unit cells of tin dioxide rather than simply attaching to the surface. Tungsten-doped SnO2 was in-situ growing on the surface of graphene sheet to form a three-dimension conductive network which enhanced the electron transportation and lithium ion diffusion effectively, as well as the issues of SnO2 agglomeration and volume expansion could be avoided because the tungsten-doped SnO2 nanoparticles were homogeneously distributed on graphene sheet...

Two novel alkali/alkaline-earth borates, Ba6[B6O9 (OH)6]2(H3BO3) (1) and Li7MAlB12O24 (M = Ba, Sr, Ca) (2a-c), with 1- and 3-D structures have been hydrothermally made and characterized. 1 features a rarely 1-D anionic chain built by hexaborate clusters of B6O11(OH)6 made of six BO4/ BO2(OH)2 tetrahedra. The anionic chains are embedded in the channels of Ba6-based wheel cluster open-framework. On the basis of the structural analyses of 1, by incorporating the rational Al atoms as the linkers and tuning the reaction conditions, the anhydrous borates 2a-c have been success-fully obtained, showing novel 3-D aluminoborates (ABOs) constructed from B6O14-based cluster chains and AlO6 octa-hedra...
