基于区域分割和DM642的数字图像修复系统研究

由于数字图像中颜色通道之间关联性显著,改变某颜色分量,会导致剩余分量随之变化,使数字图像整体视觉效果出现变化,针对该问题,文中研究基于区域分割和DM642的数字图像修复系统。将DM642处理器作为系统核心处理器,在该处理器协助下,针对破损数字图像采用基于分通道自体理论的数字图像区域分割方法,利用图像颜色信息和像素间的空间关系,实现图像修复区域分割。针对需修复区域,通过基于Criminisi算法的数字图像修复方法提取修复像素点生成修复块,利用图像自相似性,在未破损区域找到与修复块匹配度最高的样本块,用此样本填充修补破损区域。实验结果表明,此系统能够有效分割数字图像的修复区域,修复视觉效果较好,且修复后数字图像不存在明显失真问题,可实现多图像并行快速修复。

并行机器中基于干扰时间的间歇实时任务分区DM调度

间歇实时任务的分区DM(deadline-monotonic)调度是一个经典的研究问题,针对约束截止期间歇任务,提出一种具有更高处理器利用率的多核分区调度算法PDM-FFD(partitioned deadline-monotonic first-fit decrease).在PDM-FFD中,首先将任务按照其相对截止期以非递减顺序进行排序,然后采用first-fit策略选择处理器核分配任务,且在各处理器核上采用DM调度策略进行任务调度.最后通过对任务干扰时间的分析,得出一种更为紧凑的可调度性判定方法,并通过该可调度性方法来判定任务的可调度性.证明PDM-FFD的加速因子为3-(3Δ+1)/(m+Δ),时间复杂度为O(n^(2))+O(nm),其中Δ=_(Στj∈τ)C_(j)×u_(j)/D_(max),τ_(j)为任务集τ中的任务,C_(j)为该任务最差执行时间,u_(j)为该任务利用率,D_(max)为τ中的最大相对截止期,n为τ的任务数,m为处理器核数.该加速因子严格小于3-1/m,优于已有多核分区调度算法FBB-FFD.实验表明,PDM-FFD算法在4核处理器上的处理器利用率比其他算法提高了18.5%,且PDM-FFD的性能优势随着处理器核数、任务集利用率和任务数的增加而进一步扩大.由于PDM-FFD算法具有高性能特性,因此该算法可以广泛应用于资源受限的航天器、自动驾驶汽车、工业机器人等典型实时系统中.

扇贝养殖季烟台近海CH_(4)和DMS的时空分布及影响因素

甲烷(CH_(4))和二甲基硫(Dimethylsulfide,DMS)是重要的挥发性生源活性气体,在调节气候变化方面具有重要意义。本文为探究筏式扇贝养殖对CH_(4)和DMS分布与释放通量的影响,分别于2019年5、6、7、8、9和11月对烟台近海进行现场调查。结果表明,贝类滤食可以间接将水中的有机物质输入到沉积物中,导致扇贝养殖区底层CH_(4)平均浓度比非养殖区高25.64%。贝类滤食也可以将浮游植物体内的二甲基巯基丙磷(Dimethylsulfo niopropionate,DMSP)转化为海水中的颗粒态DMSP,增加DMSP向DMS的转化,与非养殖区相比,养殖区表层DMS浓度增加了24.13%。另外,表层海水CH_(4)浓度处于过饱和状态,而DMSP可能是表层海水CH_(4)重要的潜在来源。整个扇贝养殖周期内,调查海域CH_(4)海-气通量约为9.69×10^(6) g,DMS海-气通量约为3.33×10^(7) g,是大气CH_(4)和DMS重要的源。

Intense Mid-Infrared Laser Pulse Generated via Flying-Mirror Red-Shifting in Near-Critical-Density Plasmas

Relativistic femtosecond mid-infrared pulses can be generated efficiently by laser interaction with near-criticaldensity plasmas.It is found theoretically and numerically that the radiation pressure of a circularly polarized laser pulse first compresses the plasma electrons to form a dense flying mirror with a relativistic high speed.The pulse reflected by the mirror is red-shifted to the mid-infrared range.Full three-dimensional simulations demonstrate that the central wavelength of the mid-infrared pulse is tunable from 3µm to 14µm,and the laser energy conversion efficiency can reach as high as 13%.With a 0.5–10 PW incident laser pulse,the generated mid-infrared pulse reaches a peak power of 10–180 TW,which is interesting for various applications in ultrafast and high-field sciences.

Improved mass relations of mirror nuclei

In this study,we revisit the previous mass relations of mirror nuclei by considering 1/N-and 1/Z-dependent terms and the shell effect across a shell.The root-mean-squared deviation is 66 keV for 116 nuclei with neutron number N≥10,as com-pared with experimental data compiled in the AME2020 database.The predicted mass excesses of 173 proton-rich nuclei,including 98 unknown nuclei,are tabulated in the Supplemental Material herein with competitive accuracy.

Cleaning of two mirrors in the first mirror unit using radiofrequency capacitively coupled plasma

First mirror(FM)cleaning,using radio frequency(RF)plasma,has been proposed to recover FM reflectivity in nuclear fusion reactors such as the International Thermonuclear Experimental Reactor(ITER).To investigate the influence of simultaneous cleaning of two mirrors on mirror cleaning efficiency and uniformity,experiments involving single-mirror cleaning and dual-mirror cleaning were conducted using RF capacitively coupled plasma in the laboratory.For the test and simultaneous cleaning of two mirrors,the FM and second mirror(SM),both measuring 110 mm×80 mm,were placed inside the first mirror unit(FMU).They were composed of 16 mirror samples,each with a dimension of 27.5 mm×20 mm.These mirror samples consist of a titanium-zirconium-molybdenum alloy substrate,a 500 nm Mo intermediate layer and a 30 nm Al_(2)O_(3) surface coating as a proxy for Be impurities.The cleaning of a single first mirror(SFM)and the simultaneous cleaning of the FM and SM(DFM and DSM)lasted for 9 h using Ar plasma at a pressure of 1 Pa.The total reflectivity of mirror samples on the DSM did not fully recover and varied with location,with a self-bias of−140 V.With a self-bias of−300 V,the total reflectivity of mirror samples on the SFM and DFM was fully recovered.The energy dispersive spectrometer results demonstrated that the Al_(2)O_(3) coating had been completely removed from these mirror samples.However,the mass loss of each mirror sample on the SFM and DFM before and after cleaning varied depending on its location,with higher mass loss observed for mirror samples located in the corners and lower loss for those in the center.Compared with SM cleaning,the simultaneous cleaning of two mirrors reduced the difference between the highest and lowest mass loss.Furthermore,this mass loss for the mirror samples of the DFM facing the DSM was increased.This indicated that mirror samples cleaned face to face in the FMU simultaneously could influence each other,highlighting the need for special attention in future studies.

Fuzzy Proportional Integral Derivative control of a voice coil actuator system for adaptive deformable mirrors

Research on adaptive deformable mirror technology for voice coil actuators(VCAs)is an important trend in the development of large ground-based telescopes.A voice coil adaptive deformable mirror contains a large number of actuators,and there are problems with structural coupling and large temperature increases in their internal coils.Additionally,parameters of the traditional proportional integral derivative(PID)control cannot be adjusted in real-time to adapt to system changes.These problems can be addressed by introducing fuzzy control methods.A table lookup method is adopted to replace real-time calculations of the regular fuzzy controller during the control process,and a prototype platform has been established to verify the effectiveness and robustness of this process.Experimental tests compare the control performance of traditional and fuzzy proportional integral derivative(Fuzzy-PID)controllers,showing that,in system step response tests,the fuzzy control system reduces rise time by 20.25%,decreases overshoot by 78.24%,and shortens settling time by 67.59%.In disturbance rejection experiments,fuzzy control achieves a 46.09%reduction in the maximum deviation,indicating stronger robustness.The Fuzzy-PID controller,based on table lookup,outperforms the standard controller significantly,showing excellent potential for enhancing the dynamic performance and disturbance rejection capability of the voice coil motor actuator system.

An electromagnetic semi-active dynamic vibration absorber for thin-walled workpiece vibration suppression in mirror milling

As critical components of aircraft skins and rocket fuel storage tank shells,large thin-walled workpieces are susceptible to vibration and deformation during machining due to their weak local stiffness.To address these challenges,we propose a novel tunable electromagnetic semi-active dynamic vibration absorber(ESADVA),which integrates with a magnetic suction follower to form a followed ESADVA(follow-ESADVA)for mirror milling.This system combines a tunable magnet oscillator with a follower,enabling real-time vibration absorption and condition feedback throughout the milling process.Additionally,the device supports self-sensing and frequency adjustment by providing feedback to a linear actuator,which alters the distance between magnets.This resolves the traditional issue of being unable to directly monitor vibration at the machining point due to space constraints and tool interference.The frequency shift characteristics and vibration absorption performance are comprehensively investigated.Theoretical and experimental results demonstrate that the prototyped follow-ESADVA achieves frequency synchronization with the milling tool,resulting in a vibration suppression rate of approximately 47.57%.Moreover,the roughness of the machined surface decreases by18.95%,significantly enhancing the surface quality.The results of this work pave the way for higher-quality machined surfaces and a more stable mirror milling process.

Virtual Reality-Based Mirror Therapy for Upper Extremity Function among Stroke Patients:A Meta-analysis and Systematic Review

[Objectives]To investigate the evidence-based effect of virtual reality-based mirror therapy system(VR-MT)on upper extremity function among stroke patients.[Methods]A systematic electronic searching of the Medline,PubMed,Web of Science and CNKI was initially performed up to June 10,2024.The risk of bias of the included studies was evaluated using RevMan 5.4 software based on the Cochrane Handbook for Systematic Reviews.The random-effects model or fixed-effects models was employed to estimate the standardized mean difference(SMD).The subgroup analyses were conducted exploring theVR-MT type(immersive or non-immersive)and comparing with MT or control group.[Results]In total 8 studies with a total of 273 stroke patients were included in this review.The pooled analysis of these trials showed a statistically significant enhancement inFMA-UE scores(6 studies,SMD=0.72,[95%CI 0.37 to 1.06];P<0.0001,I^(2)=31%)and Box and Block Test(BBT)(3 studies,SMD=0.49,[95%C/0.05 to 0.93];P=0.03,I^(2)=0%),rather than Manual Function Test(MFT)scores(3 studies,SMD=0.38,[95%CI-0.09 to 0.84];P=0.11,I^(2)=0%)following the application of reality-based mirror therapy.Additionally,the subgroup analysis results indicated that immersive VR-MT can significantly improve FMA-UE(5studies,SMD=0.73,[95%CI 0.24 to 1.23];P=0.004,I^(2)=43%).In contrast,the overall effect of non-immersive VR-MT was non-significant(2 studies,SMD=0.33,[95%CI-0.69 to 1.34];P=0.53,I^(2)=72%).[Conclusions]In this systematic review and meta-analysis,our findings indicate that immersiveVR-MT has the potential to improve upper extremity function among stroke patients.

From Mirror Theory to Oedipus Complex:A Lacanian Interpretation of Night,Mother

Jacques Lacan reinterpreted Freud’s psychoanalytic theory based on Saussure’s linguistics,and his theories such as the Mirror stage and the Oedipus complex had a significant impact on contemporary psychoanalysis.In the play Night,Mother,the reasons for Jessie’s tragedy are diverse,among which the excessive protection of Jessie by her mother Thelma is an important reason for Jessie’s tragedy.Starting from Lacan’s Mirror stage theory and the Oedipus complex,this paper will explore how this intimate but heavy maternal love influenced Jessie’s path to finding her true“ego”.

Mannogalactoglucan from mushrooms protects pancreatic islets via restoring UPR and promotes insulin secretion in TIDM mice

Type 1 diabetes mellitus(T1DM) lacks insulin secretion due to autoimmune deficiency of pancreaticβ-cells.Protecting pancreatic islets and enhancing insulin secretion has been therapeutic approaches.Mannogalactoglucan is the main type of polysaccharide from natural mushroom,which has potential medicinal prospects.Nevertheless,the antidiabetic property of mannogalactoglucan in T1DM has not been fully elucidated.In this study,we obtained the neutral fraction of alkali-soluble Armillaria mellea polysaccharide(AAMP-N) with the structure of mannogalactoglucan from the fruiting body of A.mellea and investigated the potential therapeutic value of AAMP-N in T1DM.We demonstrated that AAMP-N lowered blood glucose and improved diabetes symptoms in T1DM mice.AAMP-N activated unfolded protein response(UPR) signaling pathway to maintain ER protein folding homeostasis and promote insulin secretion in vivo.Besides that,AAMP-N promoted insulin synthesis via upregulating the expression of transcription factors,increased Ca^(2+) signals to stimulate intracellular insulin secretory vesicle transport via activating calcium/calmodulin-dependent kinase Ⅱ(CamkⅡ) and cAMP/PKA signals,and enhanced insulin secretory vesicle fusion with the plasma membrane via vesicle-associated membrane protein 2(VAMP2).Collectively,these studies demonstrated that the therapeutic potential of AAMP-N on pancreatic islets function,indicating that mannogalactoglucan could be natural nutraceutical used for the treatment of T1DM.
