    该手稿介绍了一种创新的多级图像融合框架,该框架巧妙地集成了红外(IR)和可见光(VIS)光谱图像,以克服弱光设置带来的困难。该方法从初始预处理阶段开始,利用红外(IR)图像的有效引导图像滤波器来放大边缘边界,并利用可见光(VIS)图像的功能来增强局部对比度和亮度。利用包含基于Lipschitz约束的平滑的两尺度分解技术,图像被有效地划分为不同的基础层和细节层,从而保证基本结构信息的保存。融合过程分为两个不同的阶段:首先,采用基于贝叶斯理论的方法来有效地组合基础层,从而有效地解决任何固有的不确定性。其次,通过加强细节层的可积性,利用阴影表面(SfS)方法来确保场景几何的保留。最终采用选择最大原则来确定最突出的纹理特征,导致基础层和细节层的合并,以生成在清晰度和细节上都表现出实质性增强的图像。我们策略的有效性通过严格的测试得到证实,展示了边缘保护方面的显著进展,细节增强,和降噪。因此,我们的方法为图像分析中的实际应用提供了显着的优势。
    This manuscript introduces an innovative multi-stage image fusion framework that adeptly integrates infrared (IR) and visible (VIS) spectrum images to surmount the difficulties posed by low-light settings. The approach commences with an initial preprocessing stage, utilizing an Efficient Guided Image Filter for the infrared (IR) images to amplify edge boundaries and a function for the visible (VIS) images to boost local contrast and brightness. Utilizing a two-scale decomposition technique that incorporates Lipschitz constraints-based smoothing, the images are effectively divided into distinct base and detail layers, thereby guaranteeing the preservation of essential structural information. The process of fusion is carried out in two distinct stages: firstly, a method grounded in Bayesian theory is employed to effectively combine the base layers, so effectively addressing any inherent uncertainty. Secondly, a Surface from Shade (SfS) method is utilized to ensure the preservation of the scene\'s geometry by enforcing integrability on the detail layers. Ultimately a Choose Max principle is employed to determine the most prominent textural characteristics, resulting in the amalgamation of the base and detail layers to generate an image that exhibits a substantial enhancement in both clarity and detail. The efficacy of our strategy is substantiated by rigorous testing, showcasing notable progressions in edge preservation, detail enhancement, and noise reduction. Consequently, our method presents significant advantages for real-world applications in image analysis.

    由于化石燃料对环境的不利影响,绿色能源技术正逐渐成为亟待解决的热点问题之一。理论家和实验家正在研究和开发的策略之一是使用光电化学(PEC)电池,它们正在成为从水分解产生氢的候选者。然而,创建满足PEC水分解要求的光电极已成为将该技术实现商业成果的主要障碍。这里,我们构造了一个异质结构,它由MoS2/TiO2/Au纳米颗粒(NPs)组成,以克服光电阳极的缺点。由于对电荷转移的依赖,MoS2/TiO2的带隙和利用AuNP作为激发剂,通过局域表面等离子体共振效应以及增加热电子注入阴极,导致光催化活性得到改善。结果表明,光电流密度从TiO2的2.3μAcm-2显着增加到MoS2/TiO2/AuNP的约16.3μAcm-2。这项工作揭示了一条有希望的途径,通过将二维材料与金属NP结合来增强PEC电池光电电极中的可见光吸附和电荷转移。
    Green energy technology is generally becoming one of hot issues that need to be solved due to the adverse effects on the environment of fossil fuels. One of the strategies being studied and developed by theorists and experimentalists is the use of photoelectrochemical (PEC) cells, which are emerging as a candidate to produce hydrogen from water splitting. However, creating photoelectrodes that meet the requirements for PEC water splitting has emerged as the primary obstacle in bringing this technology to commercial fruition. Here, we construct a heterostructure, which consists of MoS2/TiO2/Au nanoparticles (NPs) to overcome the drawbacks of the photoanode. Owing to the dependence on charge transfer, the bandgap of MoS2/TiO2and the utilization the Au NPs as a stimulant for charges separation of TiO2by localized surface plasmon resonances effect as well as the increase of hot electron injection to cathode, leading to photocatalytic activities are improved. The results have recorded a significant increase in the photocurrent density from 2.3μAcm-2of TiO2to approximately 16.3μAcm-2of MoS2/TiO2/Au NPs. This work unveils a promising route to enhance the visible light adsorption and charge transfer in photo-electrode of the PEC cells by combining two-dimensional materials with metal NPs.

    获得淡水的机会有限,废水中出现的污染物(EP)的增加增加了人们对制定废水修复策略的兴趣。包括光催化。石墨碳氮化物(g-C3N4)是一种性能优异的二维非金属材料,例如2.7eV的带隙和物理化学稳定性,使其成为有前途的光催化剂。这项工作报告了使用热剥离过程获得高表面积(SA)g-C3N4的过程,以及在剥离的g-C3N4表面上负载Ag纳米颗粒的后效应。通过亚甲基蓝(MB)在可见光辐射下的降解来评估样品的光催化活性,并与其通过XRD获得的物理性质相关。TEM,BET,和UV-Vis分析。此外,在180分钟内,剥离的g-C3N4与其本体对应物(55%)相比,实现了74%的MB降解。此外,在低Ag负载下记录了更好的光催化性能(94%MB去除),5wt。%作为最优值。这种改进归因于由更高的SA产生的协同作用和Ag纳米颗粒在防止电荷复合过程中的作用。根据结果,这项工作提供了一种简单有效的方法来获得Ag/g-C3N4光催化剂,具有增强的光催化性能,足以在阳光条件下进行水修复。
    The limited access to fresh water and the increased presence of emergent pollutants (EPs) in wastewater has increased the interest in developing strategies for wastewater remediation, including photocatalysis. Graphitic carbon nitride (g-C3N4) is a 2D non-metal material with outstanding properties, such as a 2.7 eV bandgap and physicochemical stability, making it a promising photocatalyst. This work reports the process of obtaining high-surface-area (SA) g-C3N4 using the thermal-exfoliation process and the posterior effect of Ag-nanoparticle loading over the exfoliated g-C3N4 surface. The photocatalytic activity of samples was evaluated through methylene blue (MB) degradation under visible-light radiation and correlated to its physical properties obtained by XRD, TEM, BET, and UV-Vis analyses. Moreover, 74% MB degradation was achieved by exfoliated g-C3N4 compared to its bulk counterpart (55%) in 180 min. Moreover, better photocatalytic performances (94% MB remotion) were registered at low Ag loading, with 5 wt.% as the optimal value. Such an improvement is attributed to the synergetic effect produced by a higher SA and the role of Ag nanoparticles in preventing charge-recombination processes. Based on the results, this work provides a simple and efficient methodology to obtain Ag/g-C3N4 photocatalysts with enhanced photocatalytic performance that is adequate for water remediation under sunlight conditions.

    尽管多发性硬化症(MS)的治疗取得了进展,缺乏对早期MS症状的认识,尤其是在学生和公众中,导致延误诊断和治疗。这篇综述旨在找出提高认识的工具方面的差距,并提供一个双语框架来促进早期MS症状的识别。
    我们进行了文献综述,以确定在医学生和患者的MS教育中使用英语和西班牙语助记符。
    目前还没有教育工具可以帮助记住MS的早期迹象。在这里,我们提出了双语助记符VISIBLY(英语)和VISIBLE(西班牙语)中包含的早期意识框架。视觉代表(1)视力变化:痛苦的视力丧失,色觉丧失或复视;(2)腹部或背部麻木和平衡问题;(3)肢体无力或麻木;(4),年轻人.西班牙语版本包含在手稿中。
    我们假设VISIBL-MS为MS意识提供了一个框架,该框架解决了语言之间的互连,文化,健康素养,和健康结果,可以成为解决健康素养对不同社区的影响的有用教育工具。
    UNASSIGNED: Despite advancements in treatments of multiple sclerosis (MS), there is a lack of awareness of early MS symptoms, especially in students and the public, contributing to delays in diagnosis and treatment. This review aims to identify gaps in tools to increase awareness and to provide a bilingual framework to facilitate recognition of early MS symptoms.
    UNASSIGNED: We performed a literature review to determine the use of English and Spanish mnemonics in MS education for medical students and patients.
    UNASSIGNED: There is no educational tool to help remember the early signs of MS at present. Here we present a framework for early awareness encompassed in the bilingual mnemonics VISIBLY (English) and VISIBLE (Spanish). VISIBLY stands for (1) Vision changes: Painful vision loss, loss of color vision or double vision; (2) Belly or Back numbness and Balance issues; (3) Limb weakness or Numbness; (4), Young people. Spanish version is included in the manuscript.
    UNASSIGNED: We posit that VISIBL-MS provides a framework for MS awareness that addresses the interconnection between language, culture, health literacy, and health outcomes and can be a useful educational tool to tackle the effects of health literacy on diverse communities.

    基于适体未修饰的金纳米颗粒的视觉检测实验在生物技术中显示出巨大的潜力。这里,我们报告了一个可见的,无盐和高度敏感的四环素(TC)测定基于胶态稳定的AuNP混合物,该混合物包含聚(二烯丙基二甲基氯化铵)封端的AuNP((())AuNP)和四环素特异性适体封端的AuNP(Apt封端的AuNP)。该报告的TC测定是可见的且无盐的,其在TC检测期间不需要任何盐。用裸眼,纳摩尔四环素浓度可以在20分钟内确定。四环素的检测极限低至1.0fM的浓度,检测范围为8个数量级(5×10-14M至5×10-6M)。此外,报道的TC测定对四环素的选择性也优于其他抗生素,金属阳离子,蛋白质和氨基酸。这些发现清楚地证明了所报道的TC测定用于TC检测和监测的高潜力。
    Visual detection assay based on aptamer unmodified gold nanoparticles shows great potential in biotechnology. Here, we reported a visible, salt-free and highly sensitive tetracycline (TC) assay based on a colloidally stable mixture of AuNPs that contains poly (diallyl dimethylammonium chloride) capped AuNPs ((+)AuNPs) and tetracycline-specific aptamer capped AuNPs (Apt-capped AuNPs). This reported TC assay was visible and salt-free that did not need any salt during TC detection. With naked eyes, nanomolar tetracycline concentrations could be identified within 20 min. A detection limit of tetracycline down to a concentration of 1.0 fM with a broad detection range of 8 order of magnitudes (5 × 10-14 M to 5 × 10-6 M) was reached. Furthermore, the reported TC assay also exhibited good selectivity for tetracycline over other antibiotics, metal cations, proteins and amino acids. These findings clearly demonstrated the high potential of the reported TC assay for TC detection and monitoring.

    医疗保健相关感染,通常被确定为医院获得性感染(HAIs),在患者接触或入院期间通常不存在。与医疗保健相关的感染会导致住院时间延长,增加成本和死亡率。创伤患者发生HAI会增加住院时间和住院费用的风险。许多HAIs是可以预防的。抗生素抗性已经增加到高水平,使得适当的治疗由于生物体对普通抗生素具有抗性而变得越来越困难。因此,需要针对这些病原体的替代攻击形式。目前,已使用光治疗局部感染。紫外(UV)光具有有据可查的抗微生物性质。紫外线会破坏DNA并导致塑料降解,等。,所以它用于医疗目的是有限的。使用可见光可能更有希望。405nm光灭菌已被证明在减少细菌方面非常有效。LightLineMedical,Inc.。(LLM)获得专利的预防感染的可见光平台技术可能会在预防医疗保健相关感染方面产生全球转变。LLM开发了一种专有的光传递方法,以防止导管相关感染。该技术使用非UV可见光并且可以杀死两种细菌并防止腔导管内部和外部的生物膜。这很重要,因为预防是关键。对原型系统的独立分析表明,该设备的应用符合白色念珠菌减少4x109-10的验收标准,金黄色葡萄球菌,铜绿假单胞菌,和其他细菌和真菌物种。这项技术的进一步设计演变仍在继续,FDA的提交程序正在进行中。
    Healthcare-associated infections, often identified as hospital-acquired infections (HAIs), are typically not present during patient contact or admission. Healthcare-associated infections cause longer lengths of stay, increasing costs and mortality. HAI occurring in trauma patients increases the risk for length of stay and higher inpatient costs. Many HAIs are preventable. Antibiotic resistance has increased to a high level making proper treatment increasingly difficult due to organisms resistant to common antibiotics. Therefore, there is a need for alternate forms of attack against these pathogens. Currently, the application of light for the treatment of topical infections has been used. Ultraviolet (UV) light has well-documented antimicrobial properties. UV is damaging to DNA and causes the degradation of plastics, etc., so its use for medical purposes is limited. Using visible light may be more promising. 405-nm light sterilization has been shown to be highly efficacious in reducing bacteria. Light Line Medical, Inc.\'s (LLM) patented visible-light platform technology for infection prevention may create a global shift in the prevention of healthcare-associated infections. LLM has developed a proprietary method of delivering light to prevent catheter-associated infections. This technology uses non-UV visible light and can kill both bacteria and prevent biofilm inside and outside a luminal catheter. This is significant as prevention is key. Independent analysis of the prototype system showed the application of the device met the acceptance criterion of 4 x 109-10 reduction in Candida albicans, Staphylococcus aureus, Pseudomonas aeruginosa, and other bacteria and fungal species. Further design evolution for this technology continues, and the FDA submission process is underway.

    城市随着经济发展和人口增长而发展变化,台湾的城市规划法有每六年全面审查一次的规定。当前的大多数政府政策旨在增加新的防灾庇护所或救援站。提高城市规划防灾能力的一种经济方法是通过从公民或居民的角度审查或审查空间结构和防灾计划。联合国减少灾害风险办公室(UNDRR)发起了“使城市具有弹性的运动”政策,以通过综合减灾来增强抗灾和可持续的城市环境。reduction,回应,和疏散计划。本研究使用空间语法,通过几何距离分析确定疏散路线特征。在综合地图上,与无障碍道路有关的效率为31.61%。我们可以清楚地看到,由于第一象限的区域相对靠近无障碍道路,有一个区域没有连接到现有的疏散通道。频道数量的增加更容易访问和广泛。这些建议有助于政府部门做好灾害管理准备。物理环境的空间特征通过轴向地图的可访问性和效率以及通过空间语法分析的可见性进行了解释。我们的发现表明,空间语法是检查疏散图时的重要应用。
    Cities evolve and change with economic development and population growth, and urban planning laws in Taiwan have regulations that should be comprehensively reviewed every six years. Most current government policies aim to add new disaster prevention shelters or rescue stations. An economical way to improve the disaster prevention capabilities of urban planning is through examining or reviewing spatial structures and disaster prevention plans from the perspective of citizens or residents. The UN Office of Disaster Risk Reduction (UNDRR) launched the Making Cities Resilient Campaign policy to enhance disaster-resistant and sustainable urban environments through integrated disaster mitigation, reduction, response, and evacuation plans. This study used space syntax to ascertain evacuation route features using geometric distance analysis. There was 31.61% efficiency in relation to accessible roads on a comprehensive map. We could clearly see that since the areas in the first quadrant were relatively close to accessible roads, and there was an area that was not connected to the existing evacuation channels. The increased number of channels was more accessible and extensive. Such suggestions are helpful for government departments to prepare for disaster management. The spatial characteristics of the physical environment are explained by the accessibility and efficiency of axial maps and visibility analyzed by space syntax. Our findings reveal that space syntax is an important application when examining evacuation maps.
