1High-temperature infrared camouflage with efficient thermal management显示文摘High-temperature infrared(IR)camouflage is crucial to the effective concealment of high-temperature objects but remains a challenging issue,as the thermal radiation of an object is proportional to the fourth power of temperature(T4).Here,we experimentally demonstrate high-temperature IR camouflage with efficient thermal management.By combining a silica aerogel for thermal insulation and a Ge/ZnS multilayer wavelength-selective emitter for simultaneous radiative cooling(high emittance in the 5-8μm non-atmospheric window)and IR camouflage(low emittance in the 8-14μm atmospheric window),the surface temperature of an object is reduced from 873 to 410 K.The IR camouflage is demonstrated by indoor/outdoor(with/without earthshine)radiation temperatures of 310/248 K for an object at 873/623 K and a 78% reduction in with-earthshine lock-on range.This scheme may introduce opportunities for high-temperature thermal management and infrared signal processing.Huanzheng Zhu Qiang Li Chunqi Zheng Yu Hong Ziquan Xu HanWang Weidong Shen Sandeep Kaur Pintu Ghosh Min Qiu 2020Light(Science & Applications)2020,9,1:8
2基于纳米散射结构的可集成光学神经网络及其逆向设计显示文摘基于集成光学和硅光子学的光学神经网络硬件有很多优势:集成度高、速度快并且与CMOS工艺兼容.然而,目前的集成光学神经网络尺寸较大,很难扩展到大量神经元(>1000),实现大规模计算.本文提出了一种基于光学散射单元的神经网络硬件架构,除了具备一般光学神经网络的优势外,突出的优势是尺寸小,易于大规模扩展.光学散射单元允许光在一个小区域中发生散射,通过逆向设计散射区域结构,实现目标的计算功能.光学散射单元在一个很小的尺寸下,提供了很大的优化自由度,研究表明要实现一个4 4的矩阵乘法,计算单元尺寸只需要4 4μm^2.基于光学散射单元,本文设计了光学神经网络,在经典图像识别测试集MNIST上实现了97.1%的准确度.此外,这种光学散射单元还可以适用于相干光和非相干光.本研究提供了一个新的光学神经网络架构,能在不影响效率和功能下减小神经网络硬件尺寸.曲俞睿 朱桓正 沈亦晨 张津 陶陈凝 Pintu Ghosh 仇旻 2020Science Bulletin2020,65,14:7
3Thermal camouflage based on the phasechanging material GST显示文摘Camouflage technology has attracted growing interest for many thermal applications.Previous experimental demonstrations of thermal camouflage technology have not adequately explored the ability to continuously camouflage objects either at varying background temperatures or for wide observation angles.In this study,a thermal camouflage device incorporating the phase-changing material Ge2Sb2Te5(GST)is experimentally demonstrated.It has been shown that near-perfect thermal camouflage can be continuously achieved for background temperatures ranging from 30℃ to 50℃ by tuning the emissivity of the device,which is attained by controlling the GST phase change.The thermal camouflage is robust when the observation angle is changed from 0°to 60°.This demonstration paves the way toward dynamic thermal emission control both within the scientific field and for practical applications in thermal information.Yurui Qu Qiang Li Lu Cai Meiyan Pan Pintu Ghosh Kaikai Du Min Qiu 2018Light(Science & Applications)2018,7,1:3
4Endoscopic retrieval of a duodenal perforating teaspoon显示文摘Foreign objects ingestion occur commonly in pediatric patients. The majority of ingested foreign bodies pass spontaneously the gastrointestinal tract and surgery is rarely required for extraction. Endoscopic removal of foreign bodies larger than 10 cm has not yet been described. We present the case of a 16 years old bulimic girl that swallowed a 12 cm long teaspoon in order to provoke vomiting. The teaspoon perforated the duodenum. However, it was removed during gastroscopy and the site of perforation was closed endoscopically. This particular case shows the importance of endoscopy for retrieval of large foreign bodies, and the possibility to endoscopically close a perforated duodenal wall.Ivo Bokoski Andrea Tringali Rosario Landi Pietro Familiari Anna Chiara Iolanda Contini Claudio Pintus Guido Costamagna 2013World Journal of Gastrointestinal Endoscopy2013,5,4:2

6Color-preserving passive radiative cooling for an actively temperature-regulated enclosure显示文摘Active temperature control devices are widely used for the thermal management of enclosures,including vehicles and buildings.Passive radiative cooling has been extensively studied;however,its integration with existing actively temperature regulated and decorative enclosures has slipped out of the research at status quo.Here,we present a photonic-engineered dual-side thermal management strategy for reducing the active power consumption of the existing temperature-regulated enclosure without sacrificing its aesthetics.By coating the exterior and interior of the enclosure roof with two visible-transparent films with distinctive wavelength-selectivity,simultaneous control over the energy exchange among the enclosure with the hot sun,the cold outer space,the atmosphere,and the active cooler can be implemented.A power-saving of up to 63%for active coolers of the enclosure is experimentally demonstrated by measuring the heat flux compared to the ordinary enclosure when the set temperature is around 26℃.This photonic-engineered dual-side thermal management strategy offers facile integration with the existing enclosures and represents a new paradigm toward carbon neutrality.Yining Zhu Hao Luo Chenying Yang Bing Qin Pintu Ghosh Sandeep Kaur Weidong Shen Min Qiu Pavel Belov Qiang Lie 2022Light(Science & Applications)2022,11,6:2
7Emerging role of caldesmon in cancer:A potential biomarker for colorectal cancer and other cancers显示文摘Colorectal cancer(CRC) is a devastating disease, mainly because of metastasis. As a result, there is a need to better understand the molecular basis of invasion and metastasis and to identify new biomarkers and therapeutic targets to aid in managing these tumors. The actin cytoskeleton and actin-binding proteins are known to play an important role in the process of cancer metastasis because they control and execute essential steps in cell motility and contractility as well as cell division. Caldesmon(CaD) is an actin-binding protein encoded by the CALD1 gene as multiple transcripts that mainly encode two protein isoforms: High-molecular-weight CaD, expressed in smooth muscle, and low-molecular weight CaD(l-CaD), expressed in nonsmooth muscle cells. According to our comprehensive review of the literature, CaD, particularly l-CaD, plays a key role in the development, metastasis, and resistance to chemoradiotherapy in colorectal, breast, and urinary bladder cancers and gliomas, among other malignancies. CaD is involved in many aspects of the carcinogenic hallmarks, including epithelial mesenchymal transition via transforming growth factor-beta signaling, angiogenesis, resistance to hormonal therapy, and immune evasion. Recent data show that CaD is expressed in tumor cells as well as in stromal cells, such as cancerassociated fibroblasts, where it modulates the tumor microenvironment to favor the tumor. Interestingly, CaD undergoes selective tumor-specific splicing, and the resulting isoforms are generally not expressed in normal tissues, making these transcripts ideal targets for drug design. In this review, we will analyze these features of CaD with a focus on CRC and show how the currently available data qualify CaD as a potential candidate for targeted therapy in addition to its role in the diagnosis and prognosis of cancer.Alya R Alnuaimi Vidhya A Nair Lara J Bou Malhab Eman Abu-Gharbieh Anu Vinod Ranade Gianfranco Pintus Mohamad Hamad Hauke Busch Jutta Kirfel Rifat Hamoudi Wael M Abdel-Rahman 2022World Journal of Gastrointestinal Oncology2022,14,9:2
