NIPAAm has been widely used in cell culture and non-destructive desorption in recent years because it can change its surface configuration by changing temperature. In this study, NIPAAm was grafted onto the surface of the HFMs with cerium ammonium nitrate (CAN) as the initiator to prepare the thermosensitive HFMs. This material was used as a cell carrier for temperature sensitivity and biocompatibility assays to achieve non-destructive harvesting of cells from the surface of the HFMs. The morphology showed that poly (n-isopropylacrylamide) (PNIPAAm) was successfully grafted onto the HFMs. The results of water contact angle at different temperatures showed that the prepared samples have good temperature sensitivity. At 37 °C, PC12 cells adhered to and diffused well on the surface of PNIPAAm-g-HFMs. After cooling to 20 °C, the cells fell off the surface of the membrane in sheet form and retain more extracellular matrix proteins. PNIPAAm-g-HFMs in this study have good biocompatibility and can be better used as cell carriers in cell culture in vitro. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Since deep learning inference involves a significant amount of computations, there have been a lot of efforts to accelerate the inference process by eliminating ineffectual compu-tations. As a solution to this problem, several sparsity-aware deep learning accelerators have been proposed. These accelerators perform the inference on compressed data (filters and feature maps) and dynamically remove the ineffectual multiplications with zero operands. For efficiently handling the compressed data on the accelerators, a simple and effective compression scheme, which encodes the whole data with its nonzero values and their positions, is necessary. However, prior approaches have several shortcomings, such as low compression efficiency and high complexity in compression and decompression hardware. This paper proposes a low-cost compression scheme that can be applied to sparsity-aware deep-learning accelerators. The compression scheme synergistically combines two low-cost compression schemes: Zero-Value Compression (ZVC) and Base-delta-Immediate Compression (BdI). Our experimental evaluation shows that the proposed compression scheme achieves an average compression ratio of 2.26, resulting in 2.33x performance improvement, © 2025 IEEE.

In recent years, due to the installation of selective catalytic reduction (Selective Catalytic reduction, hereinafter referred to as SCr) devices, high temperature oxidation failure has occurred frequently in automobile exhaust systems. To explore its high temperature failure mechanism, this paper takes 439 ferritic stainless steel which is often used in automobile exhaust pipes as an example and uses Xrd, SEM, and EdS experimental methods to study its oxidation behavior at 700 °C, 800 °C and 900 °C. The results show that the oxide layer becomes thicker and the failure degree increases with the increase of the working temperature of 439 stainless steel. The oxidation products at different temperatures are different. When the oxidation temperature is 700 °C, the phase structure of the oxide layer on the surface of the sample is Cr2O3 and Fe2O3, and the oxide layer is dense and uniform. As the temperature rises to 800 °C, the surface oxidation products are sintered together, and the needle-like Fe2O3 structure appears on the oxide film. When the oxidation temperature rises to 900 °C, the oxide layer appears inner and outer layers, the outer layer is Fe2O3 shell structure, the inner layer is generated FeO, Fe2O3, and other iron oxides, and oxidation is very serious. At the junction of the oxide layer and the substrate, there are particles such as SiO2, TiO2, Fe2Nb in the substrate, which has a positive effect on the high temperature oxidation. © 2023 Institute of Physics Publishing.

Surface-enhanced raman spectroscopy (SErS)-based flexible substrate has recently been demonstrated to be effective in detecting molecules on curved surfaces, however a suitable method for fabricating the flexible SErS substrate still remains a hurdle. In this paper, we fabricated a flexible SErS substrate by anchoring the plasmonic gold nanoparticles (Au-NPs) onto the hydrothermally grown flower-like molybdenum disulfide (MoS2) grafted onto carbon cloth (CC) via a facile photoreduction route. Benefitting from the abundant hotspots generation of the Au-NPs and photo-induced charge-transfer ability of MoS2, the constructed Au-NPs/MoS2/CC substrate exhibit a superior SErS sensing ability, excellent SErS enhancement factor, high flexibility and mechanical stability towards the nitrofurantoin (NFT) with an ultra-low detection limit of 10−11 M. As a trial for practical applications, the flexible substrate was used to detect NFT (10−4 M) in the curved surfaces of meat samples via swab technique. The ability of the flexible Au-NPs/MoS2/CC substrate to sustain the robust raman signals of NFT even after recycling up to 4 cycles validated its reusability. The proposed flexible SErS substrate with reusable capability indicates its great potential in practical applications for the detection of target molecules on the curved surfaces. © 2023 Elsevier Ltd

Unmanned Aerial Vehicle (UAV) swarms play an essential role in emergency communication situation, especially when conventional infrastructure is under attack. Making effective routing protocols for Flying Ad Hoc Networks (FANETs) is a challenging task. Current routing protocols-which were frequently created for MANETs and VANETs-assume that UAV nodes move randomly, which is inappropriate in mission-oriented applications. The purpose of this research is to alleviate network bottlenecks in mission-oriented UAV swarms by proposing a novel 3d cone-shaped location-aided routing protocol with increased Quality of Service (QoS), called LArP-EQ. Modified Location Aided routing protocol (MLArP) balances power consumption and end-to-end (E2E) delay to maximize network performance. The outcomes of the simulation demonstrate significant improvements in 20% Packet delivery ratio (Pdr), 15% average end-to-end delay and better energy consumption over the current standards. © 2024 IEEE.

As low-voltage (LV) distribution networks evolve with the rise of prosumer behavior, traditional reactive load management strategies fall short of addressing the voltage phase imbalances caused by unpredictable load variations. Voltage imbalances pose significant risks including inefficiency, power outages, and equipment failures. Existing optimization solutions lack the adaptability to address this problem extensively with such dynamic environments due to the computational time budget limit. In response, this paper presents a novel method utilizing an Imitation Learning (IL) framework implemented through Ensemble random Forests to prune the process of sequential load phase swapping, previously determined by solely running at all times costly multi-objective optimization. We maximize classifier recall performance to ensure reliable pruning. Tested across various Solar Photovoltaic (PV) penetration levels (30-100%) on a standard 13-bus LV test feeder, our method demonstrates substantial improvements in mitigating voltage imbalance, reducing operational costs, and decreasing feeder testing time by 83%. This marks a significant step forward in smart grid technology, offering utilities a robust tool to enhance system reliability with considerable time efficiency. © 2024 IEEE.

A millimeter-wave sample and hold (S/H) mixer with LO duty cycle control is developed using 22 nm Fd-SOI CMOS technology. A direct rF undersampling receiver using an S/H mixer has been reported to achieve a small area and low power consumption. In this architecture, a timing control circuit is required to synchronize the hold period of the S/H mixer with the sample period of an analog-to-digital converter (AdC). The proposed S/H mixer allows the adjustment of the LO duty cycle by varying the gate bias voltage of LO buffers, which mitigates the resolution of the timing control circuit. The fabricated S/H mixer achieves a measured conversion gain of greater than -15 dB and measured EVM of © 2024 IEEE.

As renewable energy sources and plug-in electric vehicles increasingly penetrate power distribution systems, phase imbalance becomes more prevalent, posing significant challenges for electric utilities. This paper proactively tackles this issue by implementing phase swapping sequentially at strategic time steps and locations to improve long-term operational cost savings within a given scheduling horizon. An offline data-driven phase-swapping scheduler is developed, mimicking multi-step phase-swapping optimization through an imitation learning framework via supervised learning using random forest regression. This scheduler determines the time steps and associated loads and generations requiring phase swapping. The phase swapping over the finite scheduling horizon is modeled as a multi-step mixed-integer nonlinear programming problem, utilizing a generic branch-based radial load flow model that considers both wye and delta connections for loads and generations. For an upcoming scheduling horizon, the scheduler, based on forecasted generation, load, and price profiles, first identifies the time steps and loads/generations requiring phase swapping. Subsequently, the phase swapping actions for each determined time step are solved sequentially using a mixed-integer nonlinear optimization model with phase swapping at the determined locations and with determined number of swaps. Numerical experiments are conducted on the modified IEEE 13-node test feeder to validate the effectiveness of the proposed approach. © 2024 IEEE.

In this paper, the voltage regulation of dC-dC boost converters is investigated in the existence of unmodeled system dynamics and load perturbations. An adaptive observer based sliding mode controller (SMC) is proposed based on the radial basis function (rBF) neural networks for estimating the uncertain system function. The parameters of the rBF are updated online based on the adaptive law. The adaptive control law is developed based on the Lyapunov synthesis for the rBF model. The Lyapunov theory is utilized for proving the stability of the overall system. The chattering phenomenon is eliminated, and the robust action of the controller is ensured. For checking the effectiveness of the designed robust and adaptive controller, comparative simulations are carried out. Simulation results show better dynamic regulation of the boost converter compared to the conventional control in the presence of uncertainties and unmodeled dynamics. © 2024 IEEE.
