Complementary inverter is the basic unit for logic circuits,but the inverters based on full oxide thin-film transistors(TFTs)are still very limited.The next challenge is to realize complementary inverters using homogeneous oxide semiconduc-tors.Herein,we propose the design of complementary inverter based on full ZnO TFTs.Li-N dual-doped ZnO(ZnO:(Li,N))acts as the p-type channel and Al-doped ZnO(ZnO:Al)serves as the n-type channel for fabrication of TFTs,and then the complemen-tary inverter is produced with p-and n-type ZnO TFTs.The homogeneous ZnO-based complementary inverter has typical volt-age transfer characteristics with the voltage gain of 13.34 at the supply voltage of 40 V.This work may open the door for the development of oxide complementary inverters for logic circuits. 展开更多

As the power system transitions to a new green and low-carbon paradigm,the penetration of renewable energy in China’s power system is gradually increasing.However,the variability and uncertainty of renewable energy output limit its profitability in the electricity market and hinder its market-based integration.This paper first constructs a wind-solar-thermalmulti-energy complementary system,analyzes its external game relationships,and develops a bi-level market optimization model.Then,it considers the contribution levels of internal participants to establish a comprehensive internal distribution evaluation index system.Finally,simulation studies using the IEEE 30-bus system demonstrate that the multi-energy complementary system stabilizes nodal outputs,enhances the profitability of market participants,and promotes the market-based integration of renewable energy. 展开更多

Gait,the unique pattern of how a person walks,has emerged as one of the most promising biometric features in modern intelligent sensing.Unlike fingerprints or facial characteristics,gait can be captured unobtrusively and at a distance,without requiring the subject’s awareness or cooperation.This makes it highly suitable for long-range surveillance,forensic investigation,and smart environments where contactless recognition is crucial.Traditional gait-recognition systems rely either on silhouettes,which capture the outer appearance of a person,or on skeletons,which describe the internal structure of human motion.Each modality provides only a partial understanding of gait.Silhouettes emphasize shape and contour but are easily distorted by clothing or carried objects;skeletons describe motion dynamics and limb coordination but lose discriminative details about body shape.This article presents the concept of Complementary Semantic Embedding(CSE),a unified framework that merges silhouette and skeleton information into a comprehensive semantic representation of human walking.By modeling the complementary nature of appearance and structure,the approach achieves more robust and accurate gait recognition even under challenging conditions. 展开更多

Mild electrocatalytic nitrate reduction reaction(NO_(3)RR),driven by renewable electricity,is regarded as a desirable strategy for green ammonia synthesis and simultaneous removal of nitrogen-containing environmental pollutants.In view of different supply voltages from renewable energy sources,developing costeffective and efficient electrocatalysts with a wide operating potential window is very meaningful for practical application.However,currently reported catalysts usually need to introduce noble metals to synergistically achieve wide-potential selective ammonia synthesis from nitrate.In this work,we present for the first time a dual-transition-metal electrocatalyst(Fe_(3)C-CuO_(x)@NC,x=0,1)with wide-potential-adaptability for highly selective nitrate reduction to ammonia.Such Fe_(3)C-CuO_(x)@NC with spatially separated CuO_(x)and noblemetal-like Fe_(3)C nanoparticles encapsulated with nitrogen-doped graphitized carbon,exhibits outstanding performance in NO_(3)RR with desirable NH_(3)Faraday efficiency of more than 90%over a wide potential ranging from-0.2 V vs.RHE to-0.6 V vs.RHE,comparable to the reported noble metal catalysts.Different from common tandem catalysis,the wide-potential high ammonia selectivity of Fe_(3)C-CuO_(x)@NC is domina ntly ascribed to the complementary enhancement between CuO_(x)and Fe_(3)C,fully supported by results of experiments and density function theory calculations.CuO_(x)exhibit highly intrinsic nitrate reduction to nitrite to compensate for the slow potential determination step(^(*)NO_(3)→^(*)NO_(3)H)of Fe_(3)C,while Fe_(3)C,besides behaving like noble metals to supply adequate active hydrogens,has both good adsorption and reduction abilities for nitrite species to ammonia.Moreover,Fe_(3)C partially stabilizes active Cu^(0)/Cu^(+)sites,and the unique carbon-layer enca psulation structure effectively prevents the agglomeration and corrosion of metal nanoparticles during the electrocatalysis,thus maintaining good cyclic stability.The Zn-NO_(3)^(-)battery assembled with Fe_(3)C-CuO_(x)@NC can reach a high power density of 5.2 mW cm^(-2)at a potential of 1.0 V vs.Zn,with an NH_(3)Faraday efficiency of 92.4%at a current of 8.0 mA,proving its potential practical application.This advance provides unique insights into complementary catalysis mechanisms on multiple metal sites in NO_(3)RR,and offers a reference for the design of other transition metal electrocatalysts matching with renewable electricity. 展开更多

Background:The use of complementary and alternative medicine(CAM)is common among individuals with underlying chronic illnesses.Objective:This systematic review and meta-analysis investigated the global prevalence and patterns of CAM use among individuals with chronic kidney disease(CKD).Search strategy:PubMed,Embase,and Cumulative Index to Nursing and Allied Health Literature Plus were searched from inception until 26th February 2024.Inclusion criteria:Original articles reporting the use of at least one type of CAM among individuals aged above 18 years old and at all stages of CKD or undergoing any form of kidney replacement therapy.Data extraction and analysis:Two independent reviewers performed the literature screening.The data were extracted from the included studies by one reviewer and cross-checked by another.Discrepancies were resolved by discussion and consensus among two reviewers.Primary information included prevalence of CAM use,types of CAM used,reasons for CAM use,factors associated with CAM use,and disclosure to healthcare providers.Meta-analyses were performed to determine the pooled prevalence of CAM use and non-disclosure of CAM using a random effect model.Results:Forty-one studies were included in this systematic review and meta-analysis.The pooled prevalence of CAM use was 43%(95%confidence interval:34%,51%),I2=99.46%.The reasons for CAM use included treatment of underlying comorbidities,complications or symptoms,maintenance of general health,and treatment of CKD.Nutritional approaches were the most common CAM modality,with 412different herbal and dietary supplements reported;psychological and physical approaches included massage therapy,relaxation techniques,and mind–body practices;and other complementary health approaches such as homeopathy,traditional Chinese medicine,and Ayurvedic medicine were also frequently reported.Factors associated with CAM use included sociodemographic characteristics such as older age,female gender,or higher income;disease or therapy factors such as not having diabetes,relying on hemodialysis,or poor adherence to medication;and patient or internal factors such as positive attitude towards CAM and perceived safety of CAM.About 66%(61%,72%)of CAM users did not disclose the use of CAM to their healthcare providers.Conclusion:CAM use is prevalent among individuals with CKD,and healthcare providers should communicate openly and effectively to emphasize the rational use of CAM to avoid potential harm. 展开更多

Under the current long-term electricity market mechanism,new energy and thermal power face issues such as deviation assessment and compression of generation space.The profitability of market players is limited.Simultaneously,the cooperation model among various energy sources will have a direct impact on the alliance’s revenue and the equity of income distribution within the alliance.Therefore,integrating new energy with thermal power units into an integrated multi-energy complementary system to participate in the long-term electricity market holds significant potential.To simulate and evaluate the benefits and internal distribution methods of a multi-energy complementary system participating in long-term market transactions,this paper first constructs a multi-energy complementary system integrated with new energy and thermal power generation units at the same connection point,and participates in the annual bilateral game as a unified market entity to obtain the revenue value under the annual bilateral market.Secondly,based on the entropy weight method,improvements are made to the traditional Shapley value distribution model,and an internal distribution model for multi-energy complementary systems with multiple participants is constructed.Finally,a Markov Decision Process(MDP)evaluation system is constructed for practical case verification.The research results show that the improved Shapley value distribution model achieves higher satisfaction,providing a reasonable allocation scheme for multi-energy complementary cooperation models. 展开更多

Low sidelobe waveform can reduce mutual masking between targets and increase the detection probability of weak targets.A low sidelobe waveform design method based on complementary amplitude coding(CAC)is proposed in this paper,which can be used to reduce the sidelobe level of multiple waveforms.First,the CAC model is constructed.Then,the waveform design problem is transformed into a nonlinear optimization problem by constructing an objective function using the two indicators of peak-to-sidelobe ratio(PSLR)and integrated sidelobe ratio(ISLR).Finally,genetic algorithm(GA)is used to solve the optimization problem to get the best CAC waveforms.Simulations and experiments are conducted to verify the effectiveness of the proposed method. 展开更多

A new low power quasi adiabatic logic,complementary pass transistor adiabatic logic (CPAL),is presented.The CPAL circuit is driven by a new three phase power clock,and its non adiabatic loss on output loads can be effectively reduced by using complementary pass transistor logic and transmission gates.Furthermore,the minimization of the energy consumption can be obtained by choosing the optimal size of bootstrapped nMOS transistors,thus it has more efficient energy transfer and recovery.A three phase power supply generator with a small control logic circuit and a single inductor is proposed.An 8 bit adder based on CPAL is designed and verified.With MOSIS 0 25μm CMOS technology,the CPAL adder consumes only 35% of the dissipated energy of a 2N 2N2P adder and is about 50% of the dissipated energy of a PFAL adder for clock rates ranging from 50 to 200MHz. 展开更多
