| 1 | Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip. | Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets | 2015 | Photonics Research2015，3，5： | 7 |
| 2 | Endoscopic retrograde cholangiopancreatography guided interventions in the management of pancreatic cancer显示文摘Pancreatic cancer is the leading cause of cancer-related morbidity and mortality with an overall five-year survival of less than 9%in the United States.At presentation,the majority of patients have painless jaundice,pruritis,and malaise,a triad that develops secondary to obstruction,which often occurs late in the course of the disease process.The technical advancements in radiological imaging and endoscopic interventions have played a crucial role in the diagnosis,staging,and management of patients with pancreatic cancer.Endoscopic retrograde cholangiopancreatography(ERCP)-guided diagnosis(with brush cytology,serial pancreatic juice aspiration cytologic examination technique,or biliary biopsy)and therapeutic interventions such as pancreatobiliary decompression,intraductal and relief of gastric outlet obstruction play a pivotal role in the management of advanced pancreatic cancer and are increasingly used due to improved morbidity and complication rates compared to surgical management.In this review,we highlight various ERCP-guided diagnostic and therapeutic interventions for the management of pancreatic cancer. | Muhammad Nadeem Yousaf Hamid Ehsan Ahsan Wahab Ahmad Muneeb Fizah S Chaudhary Richard Williams Christopher J Haas | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，10： | 3 |
| 3 | Dynamic Hand Gesture Recognition Using 3D-CNN and LSTM Networks显示文摘Recognition of dynamic hand gestures in real-time is a difficult task because the system can never know when or from where the gesture starts and ends in a video stream.Many researchers have been working on visionbased gesture recognition due to its various applications.This paper proposes a deep learning architecture based on the combination of a 3D Convolutional Neural Network(3D-CNN)and a Long Short-Term Memory(LSTM)network.The proposed architecture extracts spatial-temporal information from video sequences input while avoiding extensive computation.The 3D-CNN is used for the extraction of spectral and spatial features which are then given to the LSTM network through which classification is carried out.The proposed model is a light-weight architecture with only 3.7 million training parameters.The model has been evaluated on 15 classes from the 20BN-jester dataset available publicly.The model was trained on 2000 video-clips per class which were separated into 80%training and 20%validation sets.An accuracy of 99%and 97%was achieved on training and testing data,respectively.We further show that the combination of 3D-CNN with LSTM gives superior results as compared to MobileNetv2+LSTM. | Muneeb Ur Rehman Fawad Ahmed Muhammad Attique Khan Usman Tariq Faisal Abdulaziz Alfouzan Nouf M.Alzahrani Jawad Ahmad | 2022 | Computers, Materials & Continua2022，，3： | 0 |
| 4 | Home Automation-Based Health Assessment Along Gesture Recognition via Inertial Sensors显示文摘Hand gesture recognition (HGR) is used in a numerous applications,including medical health-care, industrial purpose and sports detection.We have developed a real-time hand gesture recognition system using inertialsensors for the smart home application. Developing such a model facilitatesthe medical health field (elders or disabled ones). Home automation has alsobeen proven to be a tremendous benefit for the elderly and disabled. Residentsare admitted to smart homes for comfort, luxury, improved quality of life,and protection against intrusion and burglars. This paper proposes a novelsystem that uses principal component analysis, linear discrimination analysisfeature extraction, and random forest as a classifier to improveHGRaccuracy.We have achieved an accuracy of 94% over the publicly benchmarked HGRdataset. The proposed system can be used to detect hand gestures in thehealthcare industry as well as in the industrial and educational sectors. | Hammad Rustam Muhammad Muneeb Suliman A.Alsuhibany Yazeed Yasin Ghadi Tamara Al Shloul Ahmad Jalal Jeongmin Park | 2023 | Computers, Materials & Continua2023，，4： | 0 |
| 5 | Significantly enhanced flashover voltage of epoxy in vacuum by graded surface roughness modification显示文摘The flashover strength of epoxy(EP)insulations in the High voltage direct current applications of future energy grids can be improved by tailoring their surface condition.This work aims to improve the DC surface flashover characteristics of EP after being treated with sandpaper of different gradings.Samples with virgin EP and homogenously modified EP considering varying surface roughness(R_(a)=0.54,3.16,5.24,and 8.35μm)are prepared.Different experimental characterisations,such as water contact angle,surface intrinsic conductivity,surface voltages,flashover strength,and trap distributions are conducted and evaluated to analyse the difference between virgin and treated EP.Moreover,based on the obtained experimental results of homogenously treated EP and theoretical analysis,the concept of surface functionally graded materials(SFGMs)is put forward.The flashover voltages of homogenously treated EP are augmented significantly compared to virgin EP regardless of the voltage polarity and enhanced by enhancing the surface roughness.The sample T_(Model‐C) with SFGM design shows a 45.02%and 43.75%improvement in the negative and positive flashover voltages than that of the virgin EP.In the end,COMSOL simulations are conducted to justify the experimental findings and to analyse the difference between virgin and modified samples in terms of electric field distribution. | Inzamam Ul Haq Feipeng Wang Shakeel Akram Muneeb Ahmed Muhammad Tariq Nazir | 2023 | High Voltage2023，8，5： | 0 |
| 6 | Ergonomics of gastrointestinal endoscopies:Musculoskeletal injury among endoscopy physicians,nurses,and technicians显示文摘BACKGROUND Musculoskeletal injuries(MSI)have plagued endoscopists and ancillary staff for decades without any innovative and strong ergonomic guidelines.It has placed a physical and mental strain on our endoscopists and ancillary staff.We have very have limited data supporting this claim in our region and most data is supported by western literature.AIM To document the prevalence of MSI,and awareness and practices of ergonomics by endoscopists and ancillary staff.METHODS This is an observational cross-sectional study,conducted in Karachi,a city that boasts the maximum number of daily endoscopies in the country.An eleven-point self-administered questionnaire was distributed and used to evaluate MSI and ergonomic adjustments amongst three tertiary care setups in Karachi.An onsite survey via a 13-point checklist for endoscopy suite facilities was used to assess the ergonomically friendly conveniences at five tertiary care setups in Karachi.A total of 56 participants replied with a filled survey.RESULTS There were 56 participants in total with 39(69.6%)males.Pain and numbness were documented by 75%of the patients,with pain in the neck(41.1%),lower back(32.1%),shoulder(21.4%),thumb(12.5%),hand(23.2%),elbow(8.9%),and carpal tunnel syndrome(CTS)(7.1%).Of those,33.3%attributed their symptoms to endoscopy, 14.2% said that symptoms were not caused by endoscopy, and 52.4% were notcertain whether endoscopy had caused their symptoms. Twenty-one point four percent of patientshad to take time off their work, while 33.9% took medications for pain. Ergonomic modifications toprevent musculoskeletal injury, including placement of endoscopic monitor at eye level and thecardiac monitor in front, stopping the procedure to move patients, sitting while performingcolonoscopy, and navigating height-adjustable bed were used by 21.4%. Nine out of 13 ergonomicfacilities were not present in all five tertiary care hospitals. Conveniences, such as anti-fatiguemats, height-adjustable computer stations, and time out between patients were not present.CONCLUSIONThree-fourth of our endoscopists reported MSI, of which more than half were not sure orattributed this problem to endoscopy. The prevalence of MSI warrants urgent attention. | Samana Zainab Shah Syed Tabish Rehman Aysha Khan Muhammad Muneeb Hussain Mohsin Ali Sonaila Sarwar Shahab Abid | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，3： | 0 |
