Paris polyphylla. is a traditional medicinal herb that has long been used to prevent cancer in many Asian countries. Polyphyllin I (PPI), an important bioactive constituent of polyphylla, found exhibit wide variety anticancer activities types cells. However, the effects PPI on human gastric carcinoma cells and its mechanism action remain unclear. In this study, we examined effective anti-gastric activity underlying HGC-27 vitro, sub-micromolar concentrations inhibited cell proliferation with...

The paper derives new conditions for global convergence of the adaptive moment generation algorithm when applied on-line, or equivalently, recursive supervised learning static and dynamic nonlinear systems. also proposes a difference equation based model, that enforces {\em structure} results in type recurrent neural network. analysis applies averaging using Ljung's associated differential method. It is first proved asymptotic update behaviour equivalent to scaled stochastic gradient...

To compare the magnetic resonance imaging (MRI) features of olfactory cleft (OC) and bulbs (OBs) in patients with long COVID-19-related (LCOD) non-COVID-19 postviral dysfunction (NCPVOD) to explore mechanisms underlying persistent dysfunction. This retrospective analysis included diagnosed LCOD or NCPVOD at China-Japan Friendship Hospital between February 2023 July 2024. All underwent psychophysical testing (Sniffin' Sticks), a visual analogue scale (VAS) for function, high-resolution MRI...

Hardware structure is a basic characteristic of battery management system (BMS), which influences the overall performance packs. This paper presents novel BMS architecture based on power/data time division multiplexing transmission technique. In proposed system, common bus employed to transfer power and data simultaneously, so wiring simplified. The consists pack unit several cell units (CMUs). circuit CMU compact achieves conventional functions like status monitoring active balancing; thus,...

Visible light communication (VLC) system integrates LED lighting with wireless communication. Conventionally, power conversion and are designed separately. The circuitry added for helps to achieve a high bit rate, but increases costs impacts the efficiency. On other hand, can also be together by applying switching ripple (SRC), where no additional devices needed. However, SRC is usually achieved broadband modulation methods, which means that bandwidth much lower than frequency. By...

In direct current (dc) microgrids, communication between converters is necessary for better power distribution and finer energy scheduling. This article proposes an orthogonal frequency division multiplexing (OFDM) based carrier method dc microgrid applications. The integrates the function in process of conversion by modulating data into control loop. To maximize rate a narrow band limited pulsewidth modulation control, OFDM technology applied process. modulated to multiple low-frequency...
