We discuss data mining based on association rules for two numeric attributes and one Boolean attribute. For example, in a database of bank customers, "Age" "Balance" are attributes, "CardLoan" is Taking the pair (Age, Balance) as point two-dimensional space, we consider an rule form((Age, ∈ P) ⇒ (CardLoan = Yes),which implies that customers whose ages balances fall planar region P tend to use card loan with high probability. classes regions, rectangles admissible (i.e. connected x-monotone)...

The objectives of this paper are to propose a method that can accurately estimate the human heart rate (HR) using an ultrawideband (UWB) radar system, and determine performance proposed through measurements. uses feature points signal HR efficiently accurately. Fourier- periodicity-based methods inappropriate for estimation instantaneous HRs in real time because heartbeat waveforms highly variable, even within beat-to-beat interval. We define six waveform features enable correlation...

The strategy of structure-inherent tumor targeting (SITT) with cyanine-based fluorophores is receiving more attention because no chemical conjugation moieties required. However, the mechanism behind SITT has not yet been well explained. Here, it demonstrated that heptamethine-cyanine-based possess only targetability microenvironments without need for additional ligands but also second near-infrared spectral window (NIR-II) imaging capabilities, i.e., minimum scattering and ultralow...

Abstract Near‐infrared (NIR) fluorescence imaging has advanced medical and image‐guided interventions during the past three decades. Despite tremendous advances in devices, surprisingly only a few dyes are currently available clinic. Previous fluorophores, ZW800‐1A ZW800‐1C, significantly improved poor performance of FDA‐approved indocyanine green. However, is not stable serum ZW800‐1C induces severe stacking aqueous media. To solve such dilemmas, ZW800‐PEG was designed by introducing...

We demonstrate an accurate remote measurement of heartbeats using ultra-wideband radar system. Although most conventional systems use either continuous waves or impulse-radio for vital monitoring, suffer from non-stationary clutters, while cannot detect heartbeats. Our system has a moderate fractional bandwidth intermediate these systems, resulting in both the suppression clutters and high sensitivity measuring heart rates even dynamic environment. A simultaneous signal participant employing...

Vital-sign estimation using ultra-wideband (UWB) radar is preferable because it contactless and less privacy-invasive. Recently, many approaches have been proposed for estimating heart rate from UWB data. However, their performance still not reliable enough practical applications. To improve the accuracy, this study employs convolutional neural networks to learn special patterns of heartbeats. In system, skin displacements target person are measured radar, signal converted a two-dimensional...

Alkoxysilanes are important precursors of silicone materials for which various synthesis methods have been reported. However, these approaches not without problems, and hence, halogen-free, HF-free, room-temperature reactions producing alkoxysilanes required. In this study, we demonstrated a direct low-temperature (∼40 °C) alkoxysilane method that did involve halogens or HF. Si, Cu, ethanol were milled in planetary ball mill 2 h, 50% yield tetraethoxysilane (TEOS) was obtained; addition,...
