| 1 | Nature-inspired chiral metasurfaces for circular polarization detection and full-Stokes polarimetric measurements显示文摘The manipulation and characterization of light polarization states are essential for many applications in quantum communication and computing,spectroscopy,bioinspired navigation,and imaging.Chiral metamaterials and metasurfaces facilitate ultracompact devices for circularly polarized light generation,manipulation,and detection.Herein,we report bioinspired chiral metasurfaces with both strong chiral optical effects and low insertion loss.We experimentally demonstrated submicron-thick circularly polarized light filters with peak extinction ratios up to 35 and maximum transmission efficiencies close to 80% at near-infrared wavelengths(the best operational wavelengths can be engineered in the range of 1.3-1.6μm).We also monolithically integrated the microscale circular polarization filters with linear polarization filters to perform full-Stokes polarimetric measurements of light with arbitrary polarization states.With the advantages of easy on-chip integration,ultracompact footprints,scalability,and broad wavelength coverage,our designs hold great promise for facilitating chip-integrated polarimeters and polarimetric imaging systems for quantum-based optical computing and information processing,circular dichroism spectroscopy,biomedical diagnosis,and remote sensing applications. | Ali Basiri Xiahui Chen Jing Bai Pouya Amrollahi Joe Carpenter Zachary Holman Chao Wang Yu Yao | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 2 | Efficacy of nanofibrous conduits in repair of longsegment sciatic nerve defects显示文摘Our previous studies have histomorphologically confirmed that nanofibrous poly(3-hydroxybutyrateco-3-hydroxyvalerate) conduit can be used to repair 30-mm-long sciatic nerve defects.However,the repair effects on rat behaviors remain poorly understood.In this study,we used nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous sciatic nerve to bridge 30-mm-long rat sciatic nerve gaps.Within 4 months after surgery,rat sciatic nerve functional recovery was evaluated per month by behavioral analyses,including toe out angle,toe spread analysis,walking track analysis,extensor postural thrust,swimming test,open-field analysis and nociceptive function.Results showed that rat sciatic nerve functional recovery was similar after nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous nerve grafting.These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit is suitable in use for repair of long-segment sciatic nerve defects. | Esmaeil Biazar Saeed Heidari Keshel Majid Pouya | 2013 | Neural Regeneration Research2013，8，27： | 3 |
| 3 | The “Colonial Wig” pancreaticojejunostomy:zero leaks with a novel technique for reconstruction after pancreaticoduodenectomy显示文摘BACKGROUND: Postoperative pancreatic fistula(POPF) remains common and morbid after pancreaticoduodenectomy(PD). A major advance in the study of POPF is the fistula risk score(FRS).METHODS: We analyzed 48 consecutive patients undergoing PD. The 'Colonial Wig' pancreaticojejunostomy(CWPJ) technique was used in the last 22 PDs, we compared 22 CWPJ to 26 conventional PDs. RESULTS: Postoperative morbidity was 49%(27% Clavien grade >2). The median length of hospital stay was 11 days. In the first 26 PDs, the PJ was performed according to standard techniques and the clinically relevant POPF(CR-POPF) rate was 15%, similar to the FRS-predicted rate(14%). In the next 22 PJs, the CWPJ was employed. Although the FRS-predicted rates were similar in these two groups(14% vs 13%), the CRPOPF rate in the CWPJ group was 0(P=0.052).CONCLUSION: Early experience with the CWPJ is encouraging, and this anastomosis may be a safe and effective way to lower POPF rates. | Xihua Yang Pouya Aghajafari Naeem Goussous Shirali T Patel Steven C Cunningham | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，5： | 2 |
| 4 | 考虑资产管理原则的提高配电网自动化水平的模糊切换优化配置(英文)显示文摘由于配电部门固有的大量故障,配电公司负责达到一个可接受的可靠性指标;否则,他们将面临投诉。因此,监管机构通常有义务对网络的可靠性改进进行投资,但对可靠性的投资通常是从配电公司的角度出发的,而与顾客满意度无关。一方面,用户对配电中断的敏感性是不相同的,若只提高网络的可靠性,而没有考虑到负载的重要程度和可靠性要求的差异;另一方面,配电公司试图尽可能地降低投资成本。本文从资产管理策略的角度,介绍了一种新的联合交换机配置方法,它可以降低交换机的成本。为此,在不同类型的策略中进行了两种开关布局规划,以比较它们的结果。首先,在减少系统未提供的总能量(ENS)的基础上执行开关控制。然后,通过修改策略,从配电公司的角度进行模糊开关布局,只考虑最敏感于被称为重要或临界负荷的中断的负载点的总数。此外,通过满足相关约束,忽视低敏感用户的可靠性。这是一种基于负荷重要性的规划,它可以相对于以往策略实现的切换成本降低,并意味着与可靠性和相应约束相关的风险管理。在模糊网络环境下,采用模糊方法和新的切换机制来建模和控制与临界负荷相关的风险,并对系统的风险进行建模和控制。 | POUYA Salyani JAVAD Salehi | 2019 | Journal of Central South University2019，26，7： | 2 |
| 5 | Graphene quantum dots rescue protein dysregulation of pancreatic β-cells exposed to human islet amyloid polypeptide显示文摘The amyloid aggregation of peptides and proteins is a hallmark of neurological disorders and type 2 diabetes.Human islet amyloid polypeptide(IAPP),co-secreted with insulin by pancreaticβ-cells,plays dual roles in both glycemic control and the pathology of type 2 diabetes.While IAPP can activate the NLRP3 inflammasome and modulate cellular autophagy,apoptosis and extracellular matrix metabolism,no data is available concerning intracellular protein expression upon exposure to the polypeptide.More surprisingly,how intracellular protein expression is modulated by nanoparticle inhibitors of protein aggregation remains entirely unknown.In this study,we first examined the changing proteomes ofβTC6,a pancreaticβ-cell line,upon exposure to monomeric,oligomeric and fibrillar IAPP,and detailed cellular protein expression rescued by graphene quantum dots(GQDs),an IAPP inhibitor.We found that 29 proteins were significantly dysregulated by the IAPP species,while majority of these proteins were nucleotide-binding proteins.Collectively,our liquid chromatography tandem-mass spectrometry,fluorescence quenching,helium ion microscopy,cytotoxicity and discreet molecular dynamics simulations data revealed a remarkable capacity of GQDs in regulating aberrant protein expression through H-bonding and hydrophobic interactions,pointing to nanomedicine as a new frontier against human amyloid diseases. | Ava Faridi Yunxiang Sun Monika Mortimer Ritchlynn R.Aranha Aparna Nandakumar Yuhuan Li Ibrahim Javed Aleksandr Kakinen Qingqing Fan Anthony W.Purcell Thomas P.Davis Feng Ding Pouya Faridi Pu Chun Ke | 2019 | Nano Research2019，12，11： | 2 |

| 7 | Effects of synthesized nanoparticles and Henna-Tragacanth solutions on oil/water interfacial tension:Nanofluids stability considerations显示文摘Rising global energy demand has encouraged engineers to create and design new methods to improve oil recovery from reservoirs.In this study,feasibility of using Henna extract as a natural surfactant and synthesized nanoparticles(Titanium dioxide(TiO2),Silicon dioxide(SiO2),Graphene and composite of TiO2-Graphene)for reduction of oil-water interfacial tension has been experimentally investigated.Nanoparticles were synthesized via sol-gel method and XRD,FESEM,EDAX and FTIR tests were conducted to confirm the authenticity of this synthesizing materials.Nano-surfactants were stabled with a natural water-based suspending surfactant called Tragacanth extract,which could be introduced as a practical substitute for industrial nanoparticles'stabilizers in oil industry.After CMC determination of Henna extract surfactant,the optimal concentration of Tragacanth extract surfactant,with the purpose of nano-surfactants’stabilization,was determined through particle size and zeta potential tests.Results of interfacial tension(IFT)measurements showed that the increase of Henna extract concentration from 0 wt%to 10 wt%reduced IFT between kerosene and water from 37.23 to 15.24 mN/m.Furthermore,adding 1 wt%of synthesized TiO2 nanoparticle to the Henna extract surfactant at its CMC value reduced IFT from 18.43 to 14.57 mN/m.As an impact of this significant reduction in IFT value,oil recovery factor could be improved drastically during EOR operations.Results proved that TiO2 nano-surfactant was as effective as industrial surfactants,which put human's and environment's health at risk and impose heavy economic strain on governments. | Pouya Tavakoli Seyed Reza Shadizadeh Farzan Hayati Moslem Fattahi | 2020 | Petroleum2020，6，3： | 1 |

| 9 | Labeling Algorithm for Face Detection Using Skin and Hair Characteristics显示文摘This research presents an algorithm for face detection based on color images using three main components: skin color characteristics, hair color characteristics, and a decision structure which converts the obtained information from skin and hair regions to labels for identifying the object dependencies and rejecting many of the incorrect decisions. Here we use face color characteristics that have a good resistance against the face rotations and expressions. This algorithm is also capable of being combined with other methods of face recognition in each stage to improve the detection. | Pouya Ghofrani Zahra Neshat Hassan Aghaeinia | 2012 | Journal of Electronic Science and Technology2012，10，2： | 1 |
| 10 | Nanofibrous nerve conduits for repair of 30-mm-long sciatic nerve defects显示文摘It has been confirmed that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit can promote peripheral nerve regeneration in rats. However, its efficiency in repair of over 30-mm-long sciatic nerve defects needs to be assessed. In this study, we used a nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit to bridge a 30-mm-long gap in the rat sciatic nerve. At 4 months after nerve conduit implantation, regenerated nerves were macroscopically observed and histologically assessed. In the nanofibrous graft, the rat sciatic nerve trunk had been reconstructed by restoration of nerve continuity and formation of myelinated nerve fiber. There were Schwann cells and glial cells in the regenerated nerves. Masson's trichrome staining showed that there were no pathological changes in the size and structure of gastrocnemius muscle cells on the operated side of rats. These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit is suitable for repair of long-segment sciatic nerve defects. | Esmaeil Biazar Saeed Heidari Keshel Majid Pouya Hadi Rad Melody Omrani Nava Mohammad Azarbakhsh Shirin Hooshmand | 2013 | Neural Regeneration Research2013，8，24： | 1 |

| 14 | Parametric study of droplet size in an axisymmetric flow-focusing capillary device显示文摘A conventional technique for microfluidic droplet generation is Co-axial Flow Focusing(CFF)in which a contraction zone is placed downstream of the dispersed phase nozzle.In this contraction zone,the dispersed-phase(dphase)fluid is pinched off by continuous-phase(c-phase)fluid to generate micro-droplets.Studying the influence of multiple parameters such as the fluids velocities and viscosities,the interfacial tension,and nozzle and orifice diameters on the droplet size is of great importance for the design and application of CFF devices.Thus,development of more complete numerical models is required.In this paper,we show our model is compatible with experimental data and then numerically investigate the effects of aforementioned parameters on the droplet generation in a CFF microfluidic device.Simulation results showed that the c-phase flow rate,viscosity and the interfacial tension had great impacts on the droplet size.The effect of the nozzle diameter on the generated droplet size was small compared to that of the orifice in a CFF device.Using the simulation results,a correlation was also developed and suggested which predicts the droplet size with less than 15%error in a wide range of the introduced dimensionless parameters. | Mostafa Rahimi Sajad Yazdanparast Pouya Rezai | 2020 | Chinese Journal of Chemical Engineering2020，28，4： | 1 |
