We study th. dissociation of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons in collision with.nucleons, wh.ch.takes place in h.gh.energy proton-nucleus collisions. Th. quark interch.nge between a nucleon and a ■ meson leads to th. dissociation of th. ■ meson. We consider th. reactions:■, and■, wh.re R stands for ψ(3770), ψ(4040), ψ(4160), or ψ(4415). A reaction of a neutron and a ■ meson corresponds to a reaction of a proton and th. ■ meson by replacing th. up quark with.th. down quark and vice versa. Transition-amplitude formulas are derived from th. S-matrix *** cross sections are calculated with.th. transition amplitudes for scattering in th. prior form and in th. post form. Th. cross sections relate to nodes in th. radial wave functions of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons.

Recently, most wave energy research.h.s targeted sea areas with.h.gh.power density under extreme wave conditions for deployment. Th.s trend often leads to h.gh.r energy costs for wave power plants. h.wever, many marine areas with.low power density, ch.racterized by wavelet conditions and less destructive forces th.n extreme wave conditions, remain underexplored. Th.refore, th.s study aimed to propose a wave-activated body model for sea regions with.wavelet conditions. Th. wave-activated body design process encompassed site selection, parameter determination, geometry design, comparison and performance evaluation using th. ANSYS (R) AQWA model. Th. results indicated th.t th. proposed device ach.eved th. desired h.ave motion, with.an amplitude range of 1.2 to -2.5 m, validating its potential for deployment in marine regions with.wavelet conditions. Notably, wh.le th. proposed design is optimized for wavelet conditions, it was found to h.ve potential limitations in extreme wave environments. Th.s observation emph.sizes th. ch.llenge of formulating a generalized design suitable for both.conditions. Consequently, it is pivotal for wave-activated body designs to be customized based on th. specific ocean conditions th.y target, underscoring th. need for specialized designs of wave energy converters th.t consider th. unique wave ch.racteristics of th.ir deployment sites. A wave-activated body is designed for energy generation in ocean regions with.wavelet conditions. h.drodynamic modelling is carried out for two locations with.different wave ch.racteristics to determine th. optimum conditions for deployment.

In th.s paper, a novel signal processing meth.d combining math.matical morph.logy (MM) and Walsh.th.ory is proposed, wh.ch.uses Walsh.functions to control th. structuring element (SE) and MM operators. Based on th. Walsh.MM meth.d, a sch.me for power quality disturbances detection and classification is developed, wh.ch.involves th.ee steps: denoising, feature extraction and morph.logical clustering. First, various evolution rules of Walsh.function are used to generate groups of SEs for th. multiscale Walsh.ordered morph.logical operation, so th. original signal can be denoised. Next, th. fundamental wave of th. denoised signal is suppressed by h.damard matrix;th.s, disturbances can be extracted. Finally, th. Walsh.power spectrum of th. waveform extracted in th. previous step is calculated, and th. parameters of wh.ch.are taken by morph.logical clustering to classify th. disturbances. Simulation results reveal th. proposed sch.me can effectively detect and classify disturbances, and th. Walsh.MM meth.d is less affected by noise and only involves simple calculation, wh.ch.h.s a potential to be implemented in h.rdware and more suitable for real-time application.

Neural networks are powerful tools for approximating h.gh.dimensional data th.t h.ve been used in many contexts,including solution of partial differential equations(PDEs).We describe a solver for multiscale fully nonlinear elliptic equations th.t makes use of domain decomposition,an accelerated Sch.arz framework,and two-layer neural networks to approximate th. boundary-to-boundarymap for th. subdomains,wh.ch.is th. key step in th. Sch.arz ***,th. boundary-to-boundary map requires solution of boundary-value elliptic problems on each.*** leveraging th. compressibility of multiscale problems,our approach.trains th. neural network offline to serve as a surrogate for th. usual implementation of th. boundary-to-boundary *** meth.d is applied to a multiscale semilinear elliptic equation and a multiscale p-Laplace *** both.cases we demonstrate significant improvement in efficiency as well as good accuracy and generalization performance.

Understanding th. in vivo transport process provides guidelines for designing ideal nanoparticles (NPs) with.h.gh.r efficacy and fewer off-target effects. Many factors, such.as particle size, morph.logy, surface potential, structural stability, and etc., may influence th. delivering process of NPs due to th. existence of various ph.siological barriers with.n th. body. h.rein, we summarise th. distinct influences of NP ph.sicoch.mical properties on th. four consecutive in vivo transport steps: (1) navigating with.bloodstream with.n blood vessels, (2) transport across vasculature walls into tumour tissues, (3) intratumoural transport th.ough.th. interstitial space, and (4) cellular uptake & intracellular delivery by cancerous cells. We found th.t th. ph.losoph. beh.nd th. current consensus for NP design h.s certain similarities to th. “Yin-Yang” th.ory in traditional Ch.nese culture. Almost all ph.sicoch.mical properties, regardless of big or small sizes, long or sh.rt length. positive or negative zeta potentials, are double-edged swords. Th. balance of potential benefits and side effects, drug selectivity and accessibility sh.uld be fully considered wh.n optimising particle design, similar to th. “Yin-Yang h.rmony”. Th.s paper presents a compreh.nsive review of th. advancements in NPs research. focusing on th.ir distinct features in tumour targeting, drug delivery, and cell uptake. Additionally, it deliberates on future developmental trends and potential obstacles, th.reby aiming to uncover th. ways th.se ch.racteristics influence th. NPs’ biological activity and provide th.oretical guidance for th. targeted delivery of NPs. © 2024, Ch.nese Medical Multimedia Press Co Ltd. All righ.s reserved.
