Bouncier Particles at Night: Biogenic Secondary Organic Aerosol Chemistry and Sulfate Drive Diel Variations in the Aerosol Phase in a Mixed Forest.

Environ Sci Technol 2019 Apr 19. Epub 2019 Apr 19.

Aerosol phase state is critical for quantifying aerosol effects on climate and air quality. However, significant challenges remain in our ability to predict and quantify phase state during its evolution in the atmosphere. Herein, we demonstrate that aerosol phase (liquid, semi-solid, solid) exhibits a diel cycle in a mixed forest environment, oscillating between a viscous, semi-solid phase state at night and liquid phase state with phase separation during the day.

Meta-analysis of the role of entomopathogenic and unspecialised fungal endophytes as plant bodyguards.

New Phytol 2019 Apr 19. Epub 2019 Apr 19.

Department of Crop Protection, Agricultural Entomology, Georg-August University Goettingen, Grisebachstrasse 6, 37077, Goettingen, Germany.

Herbaceous plants harbour species-rich communities of asymptomatic endophytic fungi. While some of these endophytes are entomopathogenic, many are not, and remarkably little is known about how the presence of these fungi in plant tissues affects phytophagous insects. Here we show through a meta-analysis that both entomopathogenic and non-entomopathogenic endophytes have a negative effect on insect herbivores. Read More

Precipitation and temperature drive continental-scale patterns in stream invertebrate production.

Sci Adv 2019 Apr 17;5(4):eaav2348. Epub 2019 Apr 17.

Department of Life Sciences, Imperial College London, Silwood Park Campus, Buckhurst Rd., Ascot, Berkshire SL5 7PY, UK.

Secondary production, the growth of new heterotrophic biomass, is a key process in aquatic and terrestrial ecosystems that has been carefully measured in many flowing water ecosystems. We combine structural equation modeling with the first worldwide dataset on annual secondary production of stream invertebrate communities to reveal core pathways linking air temperature and precipitation to secondary production. In the United States, where the most extensive set of secondary production estimates and covariate data were available, we show that precipitation-mediated, low-stream flow events have a strong negative effect on secondary production.

Ultrasonography and X-Ray guided drain placement to evacuate a pneumopericardium/pneumomediastinum in a 1-day-old infant.

Indian J Radiol Imaging 2019 Jan-Mar;29(1):94-97

Children's Hospital Cardiology Center, Women's and Children's Hospital, University of Missouri Health Care, Columbia, USA.

Ultrasonographic (US) guided procedures have wide range of application in the abdomen and pelvis, however their role is somewhat limited in the chest due to complete reflection of the ultrasound beam by the air in the lungs, preventing the direct imaging of the tissues deep to the air-sound interface. Most of the chest procedures, other than the exception of thoracentesis, rely on the use of CT (computed tomography) scan. The disadvantages of using CT scan is the cost, lack of portability, and most importantly the radiation involved, particularly in case of infants and children, whose tissues are more radiosensitive than the adults.

Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol.

Nat Commun 2019 Apr 18;10(1):1803. Epub 2019 Apr 18.

Grup de Caracterizació de Materials, Departament de Física, EEBE and Barcelona Research Center in Multiscale Science and Engineering, Universitat Politècnica de Catalunya, Eduard Maristany, 10-14, 08019, Barcelona, Catalonia, Spain.

There is currently great interest in replacing the harmful volatile hydrofluorocarbon fluids used in refrigeration and air-conditioning with solid materials that display magnetocaloric, electrocaloric or mechanocaloric effects. However, the field-driven thermal changes in all of these caloric materials fall short with respect to their fluid counterparts. Here we show that plastic crystals of neopentylglycol (CH)C(CHOH) display extremely large pressure-driven thermal changes near room temperature due to molecular reconfiguration, that these changes outperform those observed in any type of caloric material, and that these changes are comparable with those exploited commercially in hydrofluorocarbons.

Femtosecond time synchronization of optical clocks off of a flying quadcopter.

Nat Commun 2019 Apr 18;10(1):1819. Epub 2019 Apr 18.

National Institute of Standards and Technology, 325 Broadway, Boulder, CO, 80305, USA.

Future optical clock networks will require free-space optical time-frequency transfer between flying clocks. However, simple one-way or standard two-way time transfer between flying clocks will completely break down because of the time-of-flight variations and Doppler shifts associated with the strongly time-varying link distances. Here, we demonstrate an advanced, frequency comb-based optical two-way time-frequency transfer (O-TWTFT) that can successfully synchronize the optical timescales at two sites connected via a time-varying turbulent air path.

High mobility group box 1 enables bacterial lipids to trigger receptor-interacting protein kinase 3 (RIPK3)-mediated necroptosis and apoptosis in mice.

J Biol Chem 2019 Apr 18. Epub 2019 Apr 18.

Department of Hematology and Key Laboratory of non-resolving inflammation and tumor, The Third Xiangya Hospital, Central South University, China.

Receptor interacting protein kinase 3 (RIPK3) is a key regulator of programmed cell death and inflammation during viral infection or sterile tissue injury. Whether and how bacterial infection also activates RIPK3-dependent immune responses remains poorly understood. Here we show that bacterial lipids (lipid IVa or lipid A) form a complex with high mobility group box 1 (HMGB1), released by activated immune cells or damaged tissue during bacterial infection, and that this complex triggers RIPK3- and TIR domain-containing adapter-inducing IFN-β (TRIF)-dependent immune responses.

UCD Dooge Centre for Water Resources Research, School of Civil Engineering, Newstead Building, University College Dublin, Belfield, Dublin 4, Ireland.

Bioelectricity production is always restricted by the limited cathode performance in integrated constructed wetland-microbial fuel cells (termed as electro-wetlands). Generally, the cathodes are located at the air-water interface for an oxygen-rich environment. However, its performance may still be unsatisfactory, resulting in a low bioelectricity production.

Measuring Environmental and Economic Performance of Air Pollution Control for Province-Level Areas in China.

Int J Environ Res Public Health 2019 Apr 17;16(8). Epub 2019 Apr 17.

Center of Ultra-Precision Optoelectronic Instrument Engineering, Harbin Institute of Technology, Harbin 150080, China.

This paper proposes an improved three-stage data envelopment analysis (DEA) model to measure the environmental-economic efficiency (EEE) of air pollution control for 30 province-level areas of China during the period of 2012 to 2016. In this model, capital, labor, and total energy consumption are the three inputs, while gross domestic product (GDP) and waste gas emissions represent the desirable and undesirable outputs, respectively. This model allows the weights of economic growth and environmental protection to be adjusted as needed by policymakers; the model is adopted to evaluate the effects of government measures on environmental protection and economic growth.

Size effects in energy transport between thermal contacts mediated by nanoparticles.

Phys Rev E 2019 Mar;99(3-1):032141

Aerospace Systems Directorate, Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio 45433, USA.

We investigate size effects in phononic energy transport in a system of two nanoparticles interconnected by a molecule and attached to thermal contacts also by molecules. In the considered closed system, the nanoparticles and contacts are described by ensembles of finite numbers of harmonic oscillators within the Drude-Ullersma model. The macroscopic character of the contacts is simulated by a large value of the ratio Δ/Δ_{B}=n (n>100) of mode spacings Δ and Δ_{B} corresponding to the nanoparticles and contacts, respectively.
