Uplink data fast transmission in CU-DU split
A method for performing uplink data fast transmission. The method includes receiving a UE context release message including a user plane ID (UPID) from control plane (CP) of a central unit (CU) of the network node, forwarding the UPID via a radio resource control (RRC) connection release message to a wireless device, receiving a RRC resume request message including user data with the UPID from the wireless device, transmitting the user data to CU based on the UPID.

Inverse Problem of Systems with Time Delay
As mentioned in the preface, time delay identification in the time domain (Chai et al. in Appl Math Comput 219:9543–9560, 2013; Hartung in Discrete Contin Dyn Syst Ser B 18:1611–1631, 2013; Lin et al. in Automatica 60:48–56, 2015; Abooshahab et al. in J Optim Theory Appl 180:1036–1064, 2019; Zhang et al. in Nonlinear Dyn 104:4045–4061, 2021 [, , , –]) may be unstable when the initial estimation is improperly set.

The developed wave cancellation theory contributing to understand wave absorption mechanism of ZIF derivatives with controllable electromagnetic parameters
How to better understand the influence of electromagnetic parameters on the absorbing properties of electromagnetic wave absorbers (EMAs) is an essential prerequisite for further synthesis and development of high‐performance EMAs. In this work, an improved wave cancellation theory is used as a guiding principle to prepare N‐doped carbon‐coated cobalt nanoparticles (Co@NC) using ZIF‐8@ZIF‐67 as the precursor, thus enabling controllable electromagnetic parameters by regulating the conduction loss and dipole polarization ability. The Co@NC generated by pyrolysis at 700 °C under H2 atmosphere presents an optimized absorption performance. Benefiting from developed wave cancellation theory, the thickness of the film can be accurately adjusted so that the difference between the amplitude of the reflected and transmitted electromagnetic waves is only 0.001 and the phase difference is 180.05°, thus …

General fabrication of hollow colloids from polymer self-assembly cavity-forming strategy
The design, preparation and property-mining of hollow colloids are the focus of current research. However, there is an urgent need for a facile, controllable, general strategy to synthesize hollow structures with tunable cavities and diverse shell properties, but this remains a major challenge. Herein, we implement a universal method for the synthesis of hollow structures from microtumblers to hollow nanoparticles by the strategy of polyglycidyl methacrylate (PGMA) self-assembly cavity formation. The strategy includes self-assembly and diffusion-controlled silication procedures. The particle diameter, cavity shape, cavity microenvironment, and shell properties are precisely adjusted by the chain structure of the polymers. Random copolymers are used to fabricate hollow microtumblers, while hollow nanoparticles are obtained due to the contribution of block copolymers. Based on this facile approach, the one-pot …

An in situ encapsulation strategy for enhancing the stability of hydrogels in both air and water through surface-confined copolymerization
Air-drying and water-swelling are significant limitations of conventional hydrogels, hindering their potential applications. In this study, we present a facile, versatile and in situ encapsulation strategy aimed at overcoming these drawbacks and enhancing the stability of hydrogels in both air and water. Our method involves creating a flexible and hydrophobic polymer coating through surface-confined copolymerization of triethoxyvinylsilane (VETS) and 2, 2, 3, 4, 4, 4-hexafluorobutyl methacrylate (HFMA), along with the infusion of a hydrophobic oil layer through hydrophobic interactions. By adjusting the monomer ratio, polymerization time, and oil viscosity, we successfully anchored a flexible double-hydrophobic-coating to the hydrogel surface without compromising its mechanical properties. This double-layer-coating acts as an effective barrier, significantly reducing water evaporation within the hydrogel and preventing …

Is there a user-friendly building unit to replicate rhythmic patterns of CPG systems? Synchrony transition and application of the delayed bursting-HCO model
The CPG neural system is an important local circuit to control rhythmic movement of vertebrates and invertebrates. The half-central oscillator (HCO), i.e. the building unit of the CPG neural circuit, should present the adjustable in-phase and anti-phase synchronous patterns. In this study, we introduce time delay into a pair of Hindmash-Rose (HR) neuronal model to construct a delayed bursting-HCO (DB-HCO) system. Employing numerical methods including phase-lag and its probability, we determine how the pattern of rhythmic activity of the DB-HCO evolves with time delay. The DB-HCO translates rhythmic activity from anti-phase to in-phase synchrony with adjusting time delay. Further, in the synchrony transition between in-phase and anti-phase states, there exist multiple types of stability coexistence including bi-stable and tri-stable stages. The DB-HCO model switches synchrony states among in-phase, anti …

Primary Cell Changing Triggered by Layer 1 and 2 Signaling
A wireless device may communicate with a base station via a primary cell (PCell) and one or more secondary cells. A plurality of types of handovers, such as a layer 1/layer 2 triggered handover or a conditional handover, may be indicated to the wireless device for switching its PCell. One or more conditions, such as a priority associated with a handover type, may be used to determine which type of handover to perform.

Network Slice Management based on Inactivity
An access and mobility management function (AMF) receives, from a unified data management (UDM), a value for a time duration associated with inactivity of a network slice for a wireless device. The AMF sends, to the wireless device and upon expiration of the time duration, an indication of removal of the network slice.
