The TransCom 3 experiment was begun to explore the estimation of carbon sources and sinks via inversion simulated tracer transport. We build upon previous work by presenting seasonal inverse results which provide estimates flux for 11 land ocean regions using 12 atmospheric transport models. monthly fluxes represent mean cycle 1992 1996 time period. spread among model is larger than average their estimated uncertainty in northern extratropics vice versa tropical regions. In regions, largest...
Using an atmospheric inversion approach, we estimate methane surface emissions for different regional sources between 1996 and 2001. Data from 13 high‐frequency 79 low‐frequency CH 4 observing sites have been averaged into monthly mean values with associated errors arising instrumental precision, mismatch error, sampling frequency. Simulated mole fractions are generated using the 3‐D global chemical transport model (MATCH), driven by NCEP analyzed observed meteorology (T62 resolution), which...
Estimates of fossil fuel CO 2 are a critical component in atmospheric inversions. Rather than solving for this portion the budget, inversions typically include estimates as known quantity. However, assumption may not be appropriate, particularly continue to solve fluxes at reduced space and timescales. In study, two different alterations made widely used emissions estimates, these altered run through series inversion experiments. The first alteration is inclusion seasonal cycle which depends...
In an H.264/AVC video encoder, integer motion estimation (IME) requires 74.29% computational complexity and 77.49% memory access becomes the most critical component for low-power applications. According to our analysis, optimal IME engine should be a parallel hardware architecture supporting fast algorithms efficient data reuse (DR). this paper, hardware-oriented algorithm is proposed with intra-/inter-candidate DR considerations. addition, based on systolic array 2-D adder tree...
Hydrogen energy is considered the most promising clean in 21st century, so hydrogen refuelling stations (HRSs) are crucial facilities for storage and supply. HRSs might experience leakage (HL) incidents during their operation. Hydrogen-producing integrated (HPRISs) could make thermal risks even more prominent than those of HRSs. Considering HL as target HPRIS, through method fault tree analysis (FTA) analytic hierarchy process (AHP), importance degree probability were appraised to obtain...
Nitrogen (N) enrichment significantly impacts temperate forest ecosystems, but we lack a comprehensive understanding of the responses root morphological characteristics, soil microbial communities, and multifunctionality concurrently to varying degrees N enrichment, particularly when exceeding threefold localized input in forests. Therefore, selected four communities China’s forests experimented with addition dominant tree species each community through bag method (three treatments were set...
TransCom 3 is an intercomparison project for CO2 source inversions. Annual mean concentration data are used to estimate sources using 16 different atmospheric transport models. Here we test the sensitivity of inversion data. We examine network choice, time period data, baseline selection and choice uncertainty used. find that in most cases regional estimates lie within range control inversion. This indicates estimated relatively insensitive changes were tested. In tests, only Australian...
As an important component of the urban ecosystem, street trees have made outstanding contribution to alleviating environmental pollution. Accurately extracting tree characteristics and species information can facilitate monitoring management trees, as well aiding landscaping studies ecology.

We extracted five attributes four combined attribute...
The last decades have witnessed a rapid increase of Earth observation satellites (EOSs), leading to the increasing complexity EOSs scheduling. On account widespread applications large region observation, this paper aims address scheduling problem for targets. A coverage calculation method employing projection reference plane and polygon clipping technique is first developed. We then formulate nonlinear integer programming model problem, where objective function calculated based on developed...
While physics-informed neural networks (PINNs) have become a popular deep learning framework for tackling forward and inverse problems governed by partial differential equations (PDEs), their performance is known to degrade when larger deeper network architectures are employed. Our study identifies that the root of this counter-intuitive behavior lies in use multi-layer perceptron (MLP) with non-suitable initialization schemes, which result poor trainablity derivatives, ultimately lead an...
Abstract A recently proposed principal law of lifespan (PLOSP) proposes to extend the whole human by elongating different life stages. As preborn stage a being, gestation is foundation for healthy development body. The antagonistic pleiotropy (AP) theory aging states that there trade‐off between early fitness and late‐life mortality. question whether slower during period would be associated with longer lifespan. Among all living creatures, length highly positively correlated lifespan,...
The most critical issue of an H.264/AVC decoder is the system architecture design with balanced pipelining schedules and proper degrees parallelism. In this paper, a hybrid task scheme first presented to greatly reduce internal memory size bandwidth. Block-level, macroblock-level, macroblock/frame-level are arranged for CAVLD/IQ/IT/INTRA/spl I.bar/PRED, INTER/spl DEBLOCK, respectively. Appropriate parallelism each pipeline also proposed. Moreover, efficient modules contributed. CAVLD unit...
We compare modeled and observed atmospheric methane (CH 4 ) between 1996 2001, focusing on the role of interannually varying (IAV) transport. The comparison uses observations taken at 13 high‐frequency (∼hourly) in situ 6 low‐frequency (∼weekly) flask measurement sites. To simulate methane, we use global 3‐D chemical transport model (MATCH) driven by NCEP reanalyzed winds T62 resolution (∼1.8° × 1.8°). For simulation, both surface emissions sink (OH destruction) are prescribed as annually...
Inverse estimation of carbon dioxide (CO 2 ) sources and sinks uses atmospheric CO observations, mostly made near the Earth's surface. However, transport models used in such studies lack perfect representation dynamics thus often fail to produce unbiased forward simulations. The error is generally larger for observations over land than those remote/marine locations. range this estimated by using multiple (16 are here). We have remaining differences fluxes due use ocean‐only versus all‐sites...

The tiltrotor design for urban air mobility (UAM) combines vertical take-off and landing (VTOL) capability with fixed-wing efficiency. However, it confronts challenges posed by downward force due to rotor wake effect. Previous research has employed active flow control, such as blowing air, primarily during forward flight using a single outlet slot. the implications performance aero-acoustic characteristics have remained unexplored. experimental approach in this study involves controlled...
