摘要:Human demands for ecosystem services (ES) have tremendously changed the landscape and led to degradation of ecosystems and associated services. The resolving of current eco-environmental problems calls for better understanding of the spatially explicit ES interactions to guide ta...

摘要:The repair of anorectal malformation (ARM) with low recto-bulbar fistula (bowel-to-skin distance: 1–1.5 cm) is contraindicated for laparoscopy due to the difficulty in exposing the fistulae. Posterior or anterior sagittal anorectoplasty is thus conventionally carried out for...

摘要:A sensitive and specific bioassay based on cyclic enzymatic amplification was developed for determination of microRNA (miRNA) by taking advantage of the exodeoxyribonuclease activity of T7 exonuclease (T7 Exo). In the presence of miRNA, DNA/RNA duplexes are formed by hybridi...

摘要:This paper presents a small-signal model for InGaAs/InP double heterojunction bipolar transistor (DHBT). Parasitic parameters of access via and electrode finger are extracted by 3-D electromagnetic (EM) simulation. By analyzing the equivalent circuit of seven special structu...

摘要:In this study, the left atrial appendage (LAA) structure and morphology were assessed using real-time three-dimensional transesophageal echocardiography (RT3D-TEE) and enhanced cardiac computed tomography (CT) scanning, and the two measurements obtained using these different...

摘要:First-principles calculations are performed to investigate the crystal and electronic structures of BiOF crystal and its oxygen vacancy BiO7/8F. By analyzing the energy band structures, the total density of states and the partial densities of states, it is found that t...

摘要:For autonomous Tonelli systems on \(\mathbb {R}^n\) , we develop an intrinsic proof of the existence of generalized characteristics using sup-convolutions. This approach, together with convexity estimates for the fundamental solution, leads to new results such as the global propa...

摘要:Abstract(#br)To eliminate crosstalk effects between reference signals of operational transfer path analysis (OTPA), a novel crosstalk cancellation method based on independent component analysis (ICA) for OTPA is proposed. Firstly, ICA is used to separate the measured signals at r...

摘要:Abstract(#br)Humans are inevitably exposed to bisphenol A (BPA) via multiple exposure ways. Thus, attention should be raised to the possible adverse effects related to low doses of BPA. Epidemiological studies have outlined BPA exposure and the increased risk of cardiovascul...

摘要:Abstract(#br)In this study, we consider a two-dimensional inverse heat conduction problem, which determines the surface temperature and heat flux distribution from measured data at the fixed location. The problem is seriously ill posed in the Hadamard sense and a conditional stab...
