Differential survival throughout the full annual cycle of a migratory bird presents a life-history trade-off.

J Anim Ecol 2021 Mar 30. Epub 2021 Mar 30.

Department of Biology and McCourt School of Public Policy, Georgetown University, Washington, DC, USA.

Long-distance migrations are among the most physically demanding feats animals perform. Understanding the potential costs and benefits of such behaviour is a fundamental question in ecology and evolution. A hypothetical cost of migration should be outweighed by higher productivity and/or higher annual survival, but few studies on migratory species have been able to directly quantify patterns of survival throughout the full annual cycle and across the majority of a species' range.

Monitoring adolescent idiopathic scoliosis by measuring ribs prominence using surface topography device.

Spine Deform 2021 Mar 29. Epub 2021 Mar 29.

Hopital Des Enfants, 330 avenue de grande Bretagne, TSA 70034, 31059, Toulouse Cedex 9, France.

Due to the danger of repeated exposure to X-rays for patients with Adolescent Idiopathic Scoliosis (AIS), reducing the number of radiographs is necessary. By using Surface Topography (ST), trunk asymmetry evaluation could be used. The number of radiographs required can be reduced by 30% when the radio is used only for patients with worsening ST.

Preparation and Characterization of Electrospun Fluoro-Containing Poly(imide-benzoxazole) Nano-Fibrous Membranes with Low Dielectric Constants and High Thermal Stability.

Nanomaterials (Basel) 2021 Feb 19;11(2). Epub 2021 Feb 19.

School of Materials Science and Technology, China University of Geosciences, Beijing 100083, China.

The rapid development of advanced high-frequency mobile communication techniques has advanced urgent requirements for polymer materials with high-temperature resistance and good dielectric properties, including low dielectric constants (low-) and low dielectric dissipation factors (low-). The relatively poor dielectric properties of common polymer candidates, such as standard polyimides (PIs) greatly limited their application in high-frequency areas. In the current work, benzoxazole units were successfully incorporated into the molecular structures of the fluoro-containing PIs to afford the poly(imide-benzoxazole) (PIBO) nano-fibrous membranes (NFMs) via electrospinning fabrication.

J Med Internet Res 2021 03 18;23(3):e27078. Epub 2021 Mar 18.

Department of Public Administration, School of Political Science and Public Administration, Shandong University, Qingdao, China.

Background: The ongoing COVID-19 pandemic has led to an increase in anxiety, depression, posttraumatic stress disorder, and psychological stress experienced by the general public in various degrees worldwide. However, effective, tailored mental health services and interventions cannot be achieved until we understand the patterns of mental health issues emerging after a public health crisis, especially in the context of the rapid transmission of COVID-19. Understanding the public's emotions and needs and their distribution attributes are therefore critical for creating appropriate public policies and eventually responding to the health crisis effectively, efficiently, and equitably.

A Sensor-Based Comprehensive Objective Assessment of Motor Symptoms in Cerebellar Ataxia.

Annu Int Conf IEEE Eng Med Biol Soc 2020 07;2020:816-819

Human observer-based assessments of Cerebellar Ataxia (CA) are subjective and are often inadequate to track mild motor symptoms. This study examines the potential use of a comprehensive sensor-based approach for objective evaluation of CA in five domains (speech, upper limb, lower limb, gait and balance) through the instrumented versions of nine bedside neurological tests.

Double-Step Modulation of the Pulse-Driven Mode for a High-Performance SnO Micro Gas Sensor: Designing the Particle Surface via a Rapid Preheating Process.

ACS Sens 2020 11 2;5(11):3449-3456. Epub 2020 Oct 2.

Department of Advanced Materials Science and Engineering, Faculty of Engineering Sciences, Kyushu University, Kasuga, Fukuoka 816-8580, Japan.

To improve the sensing properties toward volatile organic compound gases, a preheating process was introduced in a miniature pulse-driven semiconductor gas sensor, using SnO nanoparticles. The miniature sensor went through a short preheating span at a high temperature before being cooled and then experienced a measurement span under heating; this is the double-pulse-driven mode. This operating profile resulted in the modification of the surface conditions of naked SnO nanoparticles to facilitate the adsorption of O and ethanol-based adsorbates. Read More

Phosphonic Acid Modified ZnO Nanowire Sensors: Directing Reaction Pathway of Volatile Carbonyl Compounds.

ACS Appl Mater Interfaces 2020 Sep 15;12(39):44265-44272. Epub 2020 Sep 15.

Institute for Materials Chemistry and Engineering, Kyushu University, 6-1 Kasuga-Koen, Kasuga, Fukuoka 816-8580, Japan.

Surface molecular transformations on nanoscale metal oxides are inherently complex, and directing those reaction pathways is still challenging but important for designing their various applications, including molecular sensing, catalysts, and others. Here, a rational strategy to direct a reaction pathway of volatile carbonyl compounds (nonanal: biomarker) on single-crystalline ZnO nanowire surfaces via molecular modification is demonstrated. The introduction of a methylphosphonic acid modification on the ZnO nanowire surface significantly alters the surface reaction pathway of nonanal via suppressing the detrimental aldol condensation reaction.
