In prestack seismic data, outlier errors occur and can negatively influence the outcome of amplitude-versus-angle (AVA) inversion process. Hence, their effect needs to be minimized during AVA inversion. based on [Formula: see text]-norm-based likelihood function is highly sensitive errors. comparison, less affected by errors, for this reason we have used it with total variation regularization method as a constraint invert discontinuities from geologic bodies. To ensure that results contain...
Background Two recent trials demonstrated a benefit for endovascular therapy (EVT) in the treatment of basilar artery occlusion (BAO). In light expected increase use EVT BAO, we sought to understand technique preferences neurointerventionalists performing BAO. Methods We conducted an international online survey physician opinions on BAO between January and March 2022. The was distributed through stroke neurointerventional organizations. Survey questions examined selection patients procedure...
Background The best management of basilar artery occlusion (BAO) remains uncertain. BASICS (Basilar Artery International Cooperation Study) and the BEST Occlusion Endovascular Intervention Versus Standard Medical Treatment) trials reported neutral results. We sought to understand physicians’ approaches BAOs whether further BAO randomized controlled were warranted. Methods conducted an online international survey from January March 2022 stroke neurologists neurointerventionalists. Survey...
Introduction: The degree of culprit artery stenosis affects the risk early neurological deterioration (END) after acute ischemic stroke (AIS). TREND trial demonstrated efficacy tirofiban in preventing END patients with AIS. We aimed to investigate whether intracranial Patients and Methods: conducted a post hoc analysis trial, which enrolled within 24 h onset randomly allocated receive intravenous or oral aspirin. stratified degrees into three subgroups: no stenosis, mild-to-moderate...
The fermentation of oolong tea is a critical process that determines its quality and flavor. Current control relies on makers' sensory experience, which labor-intensive time-consuming. In this study, using Tieguanyin as the research object, features including water loss rate, aroma, image color, texture were obtained weight sensors, tin oxide-type gas sensor, visual acquisition system. Support vector regression (SVR), random forest (RF) machine learning, long short-term memory (LSTM) deep...
The frequency-weighted-exponential (FWE) function was designed to fit various asymmetric amplitude spectra by two parameters: symmetry index and bandwidth factor. A relation can be built between the FWE Q-factor of media. When a source wavelet propagates in attenuating media, is used attenuated obtain indexes factors. After recalculating factors based on average indexes, estimated decrease factor wavelet. Compared with existing commonly methods, this method applies types, it has better...
Due to the limitations imposed by acquisition cost, obstacles, and inaccessible regions, originally acquired seismic data are often sparsely or irregularly sampled in space, which seriously affects ability of image underground structures. Fortunately, compressed sensing provides theoretical support for interpolating recovering undersampled data. Under framework sensing, we have adopted a robust interpolation method high-dimensional data, based on elastic half norm regularization tensor...
Abstract Reliably estimating reservoir parameters is the final target in characterisation. Conventionally, characters from seismic inversion implemented by indirect approaches. The estimation of inverted elastic parameters, however, will produce large bias due to propagation errors procedure inversion. Therefore, directly obtaining prestack data through a rock-physical model and amplitude variation with offset (AVO) proposed. A generalised AVO equation terms oil-porosity (OP), sand indicator...
At an interface separating two viscoelastic media, the variation of reflection coefficient with incident angle is associated quality factors ([Formula: see text]-factors) both media; this sets up a theoretical foundation for [Formula: text]-factor inversion by amplitude (AVA). The AVA text]-factors was applied to field example gas reservoir detect gas. Considering that commonly performed obtain P- and S-wave velocities in previous interpretation seismic data, new process designed. existing...
Ischemic heart disease (IHD) remains a leading cause of morbidity and mortality worldwide, significantly burdening healthcare systems. As populations age lifestyles increasingly adopt unhealthy habits, the incidence IHD continues to rise, prompting advancements in therapeutic interventions. According World Health Organization (WHO), is death globally, accounting for millions deaths each year. The continuous evolution treatment modalities, from pharmacotherapy surgical interventions, reflects...
Background and Purpose Two early basilar artery occlusion (BAO) randomized controlled trials (RCTs) did not establish the superiority of endovascular thrombectomy (EVT) over medical management. Yet many providers continued to recommend EVT. The goal present article is compare physicians’ diagnostic management strategies BAO among middle-income high-income countries (MICs HICs, respectively). Methods We conducted an international survey from January March 2022 regarding in acute BAO, examine...
Gas hydrate saturation is an important index for evaluating gas reservoirs, and well logs are effective method estimating saturation. To use better to estimate saturation, establish the deep internal connections laws of data, we propose a using learning technology from logs. Considering that have sequential characteristics, used long short-term memory (LSTM) recurrent neural network predict two sites in Shenhu area, South China Sea. By constructing LSTM layer fully connected layers at one...

Balance energy consumption between can reduce the dead prolong network lifetime. In this paper, based on novel clustering algorithm Affinity Propagation (AP), efficient cluster head selection (PECBA) is proposed to select heads considering balance for multi-level heterogeneous WSNs. our algorithm, optimal first chosen according distance any two ratio each node's...
ABSTRACT Seismic reflectivity inversion using l 1 ‐norm regularization produces sparse solutions by applying an constraint. The fast iterative shrinkage‐thresholding algorithm is one of the most effective methods to solve regularized problems. A large number iterations are commonly required in because its solution converges slowly towards solution. To improve convergence rate, we introduce a modifying strategy for traditional algorithm. When implementing soft‐thresholding operator,...
