Increasing demand for food, driven by unprecedented population growth and increasing consumption, will keep challenging food security in China. Although cereal yields have substantially improved during the last three decades, whether it thriving to meet is not known yet. Thus, an integrated analysis on trends of crop yield cultivated area essential better understand current state China, especially county scale. So far, stagnation has extensively dominated main cereal-growing areas across...
Dynamical tide consists of various waves that can resonate with orbital motion. We test this coupling dynamical and motion using a simple two-dimensional shallow water model, which be applied to rocky planet covered thin ocean or atmosphere. Then we take the earth-moon system as fiducial model calculate tidal resonances evolution. find dissipation even increase increasing separation because draw conclusion is not negligible study evolution on secular timescale.

Background Inherited deficiency of antithrombin, protein C and S, three important, naturally occurring coagulation inhibitors, might play a major role in the occurrence venous thromboembolism Chinese. The establishment age- gender-related normal ranges these inhibitors is crucial for an accurate diagnosis deficiencies.Design Methods We designed prospective cross-sectional study recruiting healthy adults from four university–affiliated hospitals China. Antithrombin, S were studied by...
We investigate numerically the Princeton magnetorotational instability (MRI) experiment and effect of conducting axial boundaries or endcaps. MRI is identified found to reach a much higher saturation than for insulating This probably due stronger driving base flow by magnetically rather viscously coupled boundaries. Although computations are necessarily limited lower Reynolds numbers (Re) their experimental counterparts, it appears that level becomes independent Re when sufficiently large,...
ABSTRACT 1ES 1927+654 was known as a type 2 Seyfert galaxy, which exhibited drastic variability recently in ultraviolet (UV)/optical and X-ray bands. An UV/optical outburst observed the end of 2017, it reached peak luminosity ∼50 d later. The high-cadence observations showed rapid flux decline with complete disappearance power-law hard component when soft thermal emission its lowest level about 150 after peak. reappeared brightening from within next ∼100 d. We assume an episodic accretion...
Abstract We study the magnetic and tidal interactions of a gas-giant exoplanet with its host star exomoons, focus on their retention. briefly revisit scaling law for planetary dynamo in terms mass, radius, luminosity. Based virial theorem, we construct an evolution field find that initial entropy is important high-mass planet. estimate torques orbit arising from star–planet planet–moon interactions, it can compensate bypass frequency valleys where dynamical-tide response ineffective. For...
Reducing ammonia (NH3) volatilization is a practical way to increase nitrogen (N) fertilizer use efficiency (NUE). In this field study, soil was amended once with either cotton (Gossypium hirsutum L.) straw (6 t ha−1) or its biochar (3.7 unfertilized (0 kg N fertilized (450 ha−1), and then inorganic concentration distribution, NH3 volatilization, yield NUE were measured during the next two growing seasons. plots, losses in straw-amended biochar-amended treatments 38–40% 42–46%, respectively,...
Abstract Observed transit timing variation (TTV) potentially reveals the period decay caused by star-planet tidal interaction which can explain orbital migration of hot Jupiters. We report TTV XO-3b, using TESS observed timings and archival timings. generate a photometric pipeline to produce light curves from raw images find difference between our PDC is negligible for analysis. presents shift 17.6 minutes (80 σ ), earlier than prediction previous ephemeris. The best linear fit all available...
We explore numerically the flow induced in a spherical shell by differentially rotating inner and outer spheres. The fluid is also taken to be electrically conducting (in low magnetic Reynolds number limit), field imposed parallel axis of rotation. If sphere stationary, induces Shercliffe layer on tangent cylinder, cylinder just touching field. absent, but strong overall rotation present, Coriolis effects induce Stewartson cylinder. nonaxisymmetric instabilities both types separately have...
We investigate numerically in spherical geometry the interaction of stratification with precession. Both stable and unstable are studied. In parameter regime we concerned with, suppresses precessional instability, whereas precession can either stablise or destablise each other at different rates.
The aim of this work is to investigate the effect shaft eccentricity on flow field and mixing characteristics in a stirred tank with novel stirrer composed perturbed six-bent-bladed turbine (6PBT). difference between coaxial eccentric agitations studied using computational fluid dynamics (CFD) simulations combined standard k−ε turbulent equations, that offer complete image three-dimensional field. In order determine capability CFD forecast process, particle velocimetry (PIV), which provide...
The aerated power consumption characteristics in a transparent tank with diameter of 0.3 m and flat bottom stirred by Rushton impeller were investigated means experimental measurement. test fluid used was tap water as liquid air gas. Based on Weibull model, the complete correlation flow number established through non-linear fit analysis. effects rate speed made an exploration. Results show that changeable trend is found to be similar under different speeds diameters, i.e. close dropping...
Abstract We consider the flow of an electrically conducting fluid confined in a rotating spherical shell. The is driven by directly imposed electromagnetic body force, created combination electric current flowing from inner sphere to ring-shaped electrode around equator outer and separately predominantly axial magnetic field. begin numerically computing axisymmetric basic states, which consist strong zonal flow. next compute linear onset non-axisymmetric instabilities, fully...
Tidal heating is often used to interpret "radius anomaly" of hot Jupiters (i.e. radii a large fraction are in excess 1.2 Jupiter radius which cannot be interpreted by the standard theory planetary evolution). In this paper we find that tidal induces another phenomenon "runaway inflation" planet inflation becomes unstable and out control when rate above its critical value). With sufficiently strong heating, luminosity initially increases with inflation, but across peak it decreases such...
In the standard theory of equilibrium tides, hydrodynamic turbulence is considered. this paper we study effect magnetic fields on tides. We find that turbulent Ohmic dissipation associated with a tidal flow much stronger than viscous such field can greatly speed up evolution binary system. then apply to three systems: orbital migration 51 Pegasi b, decay WASP-12b, and circularization close stars. Theoretical predictions are in good agreement observations, which cannot be clearly interpreted
Aims To examine the associations of sleep duration and changes in BMI with onset diabetic kidney disease (DKD). Materials methods 2,959 participants type 2 diabetes were divided into three groups based on duration: short (<7 h/day), intermediate (7-9 or long (>9 h/day). Changes during follow-up trisected loss, stable, gain groups. DKD was defined as either urinary albumin/creatinine ratio (UACR) ≥ 3.39 mg/mmol estimated glomerular filtration rate (eGFR) < 60...
Abstract A new algebraic turbulent mass flux model (AFM), which properly accounts for swirl–turbulence interactions, is proposed and formulated in the present article. simplified explicit form of this AFM derived. By incorporating with Reynolds stress previously, a stress/flux (ASM/AFM) obtained. The ASM/AFM applied to simulation swirling flow mixing combustor helium/air jet air stream. calculated gas axial tangential velocities, fluctuating helium concentration are agreement measured test...
