Compressed sensing is a sampling technique which provides fundamentally new approach to data acquisition. Comparing with traditional methods, compressed makes full use of sparsity so that sparse signal can be reconstructed from very few measurements. A central problem in the construction matrices. While random matrices have been studied intensively, only deterministic constructions are known. Inspired by algebraic geometry codes, we introduce via curves over finite fields, natural...
Anomaly detection is critical in identifying abnormal patterns big data environments, where traditional techniques often struggle with scalability and efficiency. This paper explores machine learning-based anomaly techniques, focusing on their effectiveness large-scale biomechanical contexts. The study investigates three prominent methods: K-means clustering, autoencoders, One-Class Support Vector Machine (SVM), each known for distinct strengths handling data. Through comprehensive...
Geochemical anomaly mapping is a crucial part of environmental and mineral exploration projects. Stream sediments are the most frequently sampling medium for geochemical in regional scales, resulting from various geological processes. To enhance stream sediments, landscape, including topographic factors drainage catchment basin extracted digital elevation model (DEM), average precipitations, were applied. These taken into consideration this research to investigate influence landscape...
Delineation of geochemical anomalies is a fundamental task in mineral and environmental investigation. Mineralization area interest mainly controlled by underlying geological environment. These constraints facilitate to identify mineralization remove pseudo-anomalies. Regional data one most commonly used deriving information, which also considered be the primary for direct anomaly identification. The selected study area, Jining central Inner Mongolia China, mostly covered with Quaternary...
The aromatization mechanisms of ligustilide (1), a versatile monomeric phthalide, were investigated. DFT calculations combined with control experiments prove that the could result from direct oxidation by triplet oxygen in mild conditions no catalyst, which is generally thought to be difficult. Moreover, it predicted rapidly clear away harmful-to-organism singlet oxygen, may relevant general antioxidation activity phthalides, providing new point view understand bioactivity chemical reaction.
New classes of zero-difference balanced (ZDB) functions derived from Fermat quotients are proposed in this letter. Based on the new ZDB functions, some applications, such as construction optimal frequency hopping sequences set and perfect difference systems sets, introduced.
[reaction: see text] Two types of trisaza-bridged [60]fulleroids have been synthesized for the first time. By means (13)C NMR, (1)H MALDI-TOF MS, FTIR, UV-vis, and 2D-NMR (gHSQC, gHMBC, NOSEY) spectroscopy, they shown to be tris[6,5]-opened-aza-bridged adducts with substituents on same five-membered ring C(s)() symmetry. Some data nonlinear optics electrochemistry product are also reported.
