| 1 | Microstructure and mechanical properties of Cu-B4C and CuAl-B4C composites produced by hot pressing显示文摘Cu matrix composite materials reinforced with B4C particle at four different contents(1.5 wt%,3.0 wt%,4.5 wt% and 6.0 wt%) and also CuAl matrix composites with 13 wt% Al reinforced with B4C particle at four different contents(1.5 wt%,3.0 wt%,4.5 wt% and 6.0 wt%)were fabricated by hot pressing(HP) and a powder metallurgy(PM) process.Experimental samples were produced by keeping them at 880℃ at the constant pressure of 2.3×10~8 Pa for 6 min.The density,microstructure and mechanical properties of the produced samples were examined.The microstructure and phase examinations were carried out by scanning electron microscope(SEM)and optical microscope(OM),energy-dispersive spectrometer(EDS) and X-ray diffractometer(XRD) analysis.The hardness measurements,three-point bending test and impact test were conducted to determine the mechanical properties.As a result of the examinations,it was observed that the relative density values decreased with the increasing content of B4C and provided a relatively effective bonding.Moreover,it was homogeneously distributed in the produced specimens.Consequently,there was a considerable increase in the hardness and the bending strength of CuAl matrix specimens with Al addition. | Zulkuf Balalan Furkan Gulan | 2019 | Rare Metals2019，38，12： | 3 |
| 2 | Development of an Amperometric Hydrogen Peroxide Biosensor based on the Immobilization of Horseradish Peroxidase onto Nickel Ferrite Nanoparticle-Chitosan Composite显示文摘Nickel ferrite(NiFe_2O_4) nanoparticles have been dispersed in chitosan solution in order to fab ricate nanocomposite films.Horseradish peroxidase(HRP) has been immobilized onto this chitosan NiFe_2O_4 nanocomposite film via physical adsorption.The size of the NiFe_2O_4 nanoparticles has been estimated us ing X ray diffraction pattern and scanning electron microscopy(SEM) to be 40±9 nm.The chitosan NiFe_2O_4 nanocomposite film and HRP/chitosan NiFe_2O_4 bioelectrode have been characterized using SEM technique.The HRP/chitosan NiFe_2O_4 nanocomposite bioelectrode has a response time of 4 s,linearity as 0.3 to 12 m M of H2O2,sensitivity as 22 n A/m M.The effects of p H and the temperature of the immobilized HRP electrode have also been studied. | Furkan Yalcner Emre Cevik Mehmet Senel Abdulhadi Baykal | 2011 | Nano-Micro Letters2011，3，2： | 2 |
| 3 | Improved Blocking Time Analysis and Evaluation for the Multiprocessor Priority Ceiling Protocol显示文摘The Multiprocessor Priority Ceiling Protocol(MPCP) is a classic suspension-based real-time locking protocol for partitioned fixed-priority(P-FP) scheduling. However,existing blocking time analysis is pessimistic under the P-FP +MPCP scheduling,which negatively impacts the schedulability for real-time tasks. In this paper,we model each task as an alternating sequence of normal and critical sections,and use both the best-case execution time(BCET) and the worst-case execution time(WCET) to describe the execution requirement for each section. Based on this model,a novel analysis is proposed to bound shared resource requests. This analysis uses BCET to derive the lower bound on the inter-arrival time for shared resource requests,and uses WCET to obtain the upper bound on the execution time of a task on critical sections during an arbitrary time interval of △t. Based on this analysis,improved blocking analysis and its associated worst-case response time(WCRT) analysis are proposed for P-FP + MPCP scheduling. Schedulability experiments indicate that the proposed method outperforms the existing methods and improves the schedulability significantly. | 杨茂林 雷航 廖勇 Furkan Rabee | 2014 | Journal of Computer Science & Technology2014，29，6： | 2 |
| 4 | Phase I study on the safety and preliminary efficacy of allogeneic mesenchymal stem cells in hypoxic-ischemic encephalopathy显示文摘BACKGROUND Hypoxic-ischemic encephalopathy(HIE)is a leading cause of morbidity and mortality in the adult as well as in the neonate,with limited options for treatment and significant dysfunctionality.AIM To investigate the safety and preliminary efficacy of allogeneic mesenchymal stem cells(MSCs)in HIE patients.METHODS Patients who had HIE for at least 6 mo along with significant dysfunction and disability were included.All patients were given Wharton’s jelly-derived MSCs at 1×106/kg intrathecally,intravenously,and intramuscularly twice a month for two months.The therapeutic effects and prognostic implications of MSCs were evaluated by multiple follow-ups.Functional independence measure(FIM),modified Ashworth,and Karnofsky scales were used to assess any side effects,neurological and cognitive functions,and overall outcomes.RESULTS The 8 subjects included in the study had a mean age of 33.25±10.18 years.Mean HIE exposure and mean post-HIE durations were 45.63±10.18 and 19.67±29.04 mo,respectively.Mean FIM score was 18.38±1.06,mean modified Ashworth score was 43.5±4.63,and mean Karnofsky score was 20.For the first 24 h,5 of the patients experienced a subfebrile state,accompanied by mild headaches due to intrathecally administration and muscle pain because of intramuscularly administration.Neurological and functional examinations,laboratory tests,electroencephalography,and magnetic resonance imaging were performed to assess safety of treatment.Mean FIM score increased by 20.88±3.31 in the first month(P=0.027)and by 31.38±14.69 in 12 mo(P=0.012).The rate of patients with an FIM score of 126 increased from 14.58%to 16.57%in the first month and 24.90%in 12 mo.CONCLUSION Multiple triple-route Wharton’s jelly-derived MSC administrations were found to be safe for HIE patients,indicating neurological and functional improvement.Based on the findings obtained here,further randomized and placebo research could be performed. | Serdar Kabataş ErdinçCivelek Necati Kaplan Eyüp Can Savrunlu Gülseli Berivan Sezen Mourat Chasan Halil Can Ali Genç Yener Akyuva Osman Boyalı Furkan Diren Erdal Karaoz | 2021 | World Journal of Experimental Medicine2021，11，2： | 2 |
| 5 | Connected autonomous vehicles for improving mixed traffic efficiency in unsignalized intersections with deep reinforcement learning显示文摘Human driven vehicles(HDVs)with selfish objectives cause low traffic efficiency in an un-signalized intersection.On the other hand,autonomous vehicles can overcome this inefficiency through perfect coordination.In this paper,we propose an intermediate solution,where we use vehicular communication and a small number of autonomous vehicles to improve the transportation system efficiency in such intersections.In our solution,two connected autonomous vehicles(CAVs)lead multiple HDVs in a double-lane intersection in order to avoid congestion in front of the intersection.The CAVs are able to communicate and coordinate their behavior,which is controlled by a deep reinforcement learning(DRL)agent.We design an altruistic reward function which enables CAVs to adjust their velocities flexibly in order to avoid queuing in front of the intersection.The proximal policy optimization(PPO)algorithm is applied to train the policy and the generalized advantage estimation(GAE)is used to estimate state values.Training results show that two CAVs are able to achieve significantly better traffic efficiency compared to similar scenarios without and with one altruistic autonomous vehicle. | Bile Peng Musa Furkan Keskin Balazs Kulcsar Henk Wymeersch | 2021 | Communications in Transportation Research2021，1，1： | 2 |
| 6 | Open reduction of a total talar dislocation: A case report and review of the literature显示文摘BACKGROUND Total talar dislocation (TTD) is very uncommon for many orthopedic surgeons and emergency/trauma specialists. Scarce cases of TTD have been reported, mainly in the form of open fracture-dislocation injury. CASE SUMMARY We report a very rare injury of closed TTD with a follow-up period of 36 mo. Initial closed reduction was not successful because of a fractured highly unstable medial malleolus displaced into the ankle mortise, blocking the relocation of the talus. The patient was able to walk pain-free after the 3rd month of surgery. At the 36-mo follow-up, there were 10 degrees of flexion loss and 10 degrees of extension loss in the tibiotalar joint. Furthermore, 5 degrees of subtalar joint inversion-eversion loss was present. CONCLUSION Open reduction should be performed for closed TTDs unless closed reduction is successful. | Furkan Yapici Mehmet Coskun Muhammet Coskun Arslan Erman Ulu Yunus Emre Akman | 2019 | World Journal of Clinical Cases2019，7，14： | 2 |
| 7 | Feasibility of allogeneic mesenchymal stem cells in pediatric hypoxic-ischemic encephalopathy: Phase I study显示文摘BACKGROUND Hypoxic-ischemic encephalopathy(HIE)is one of the leading causes of death and long-term neurological impairment in the pediatric population.Despite a limited number of treatments to cure HIE,stem cell therapies appear to be a potential treatment option for brain injury resulting from HIE.AIM To investigate the efficacy and safety of stem cell-based therapies in pediatric patients with HIE.METHODS The study inclusion criteria were determined as the presence of substantial deficit and disability caused by HIE.Wharton’s jelly-derived mesenchymal stem cells(WJ-MSCs)were intrathecally(IT),intramuscularly(IM),and intravenously administered to participants at a dose of 1×10^(6)/kg for each administration route twice monthly for 2 mo.In different follow-up durations,the effect of WJ-MSCs administration on HIE,the quality of life,prognosis of patients,and side effects were investigated,and patients were evaluated for neurological,cognitive functions,and spasticity using the Wee Functional Independence Measure(Wee FIM)Scale and Modified Ashworth(MA)Scale.RESULTS For all participants(n=6),the mean duration of exposure to hypoxia was 39.17+18.82 min,the mean time interval after HIE was 21.83±26.60 mo,the mean baseline Wee FIM scale score was 13.5±0.55,and the mean baseline MA scale score was 35±9.08.Three patients developed only early complications such as low-grade fever,mild headache associated with IT injection,and muscle pain associated with IM injection,all of which were transient and disappeared within 24 h.The treatment was evaluated to be safe and effective as demonstrated by magnetic resonance imaging examinations,electroencephalographies,laboratory tests,and neurological and functional scores of patients.Patients exhibited significant improvements in all neurological functions through a 12-mo follow-up.The mean Wee FIM scale score of participants increased from 13.5±0.55 to 15.17±1.6 points(mean±SD)at 1 mo(z=-1.826,P=0.068)and to 23.5±3.39 points at 12 mo(z=-2.207,P=0.027)post-treatment.The percentage of patients who achieved an excellent functional improvement(Wee FIM scale total score=126)increased from 10.71%(at baseline)to 12.03%at 1 mo and to 18.65%at 12 mo posttreatment.CONCLUSION Both the triple-route and multiple WJ-MSC implantations were safe and effective in pediatric patients with HIE with significant neurological and functional improvements.The results of this study support conducting further randomized,placebo-controlled studies on this treatment in the pediatric population. | Serdar Kabatas Erdinç Civelek Eyüp Can Savrunlu Necati Kaplan Osman Boyalı Furkan Diren Halil Can Ali Genç Tunç Akkoç Erdal Karaöz | 2021 | World Journal of Stem Cells2021，13，5： | 2 |

| 10 | Evaluation of stiffness in a cellulose fiber reinforced epoxy laminates for structural applications:Experimental and finite element analysis显示文摘Natural fiber composites have been proved to have the ability to replace the synthetic fiber composites in many structural applications. Unprecedented growth in the field of computational techniques has opened the doors of analysis and simulation of composite materials under various environment.Modelling and simulation using various available softwares saves a lot of time and resources. In the present work, an attempt has been made to analyze the tensile behavior of jute fiber reinforced epoxy based polymer composite materials using the student version of commercially available finite element code Siemens PLM NX 10.0. In most of the structural applications, materials are required to have enough stiffness to resist the shape deformation under normal loading conditions. Therefore, emphasis is given to the load-deformation behavior of the developed composites. A 3-dimensional model of the test specimen was developed using ply-stacking method and the strain-stress values were verified by the available literature. The model showed a good agreement between the experimental and software results. Effect of ply angle, fiber percentage, fiber type, number of layers and weft fiber angle on the stiffness of laminate have been studied. | Furkan Ahmad Pramendra Kumar Bajpai | 2018 | Defence Technology(防务技术)2018，14，4： | 1 |

| 14 | Revisiting the Bjerrum's correction factor:Use of the liquidity index for assessing the effect of soil plasticity on undrained shear strength显示文摘The undrained shear strength(s_u) of fine-grained soils that can be measured in situ and in laboratory is one of the key geotechnical parameters.The unconfined compression test(UCT) is widely used in laboratory to measure this parameter due to its simplicity;however,it is severely affected by sample disturbance.The vane shear test(VST) technique that is less sensitive to sample disturbance involves a correction factor against the soil plasticity,commonly known as the Bjerrum's correction factor,μ.This study aims to reevaluate the Bjerrum's correction factor in consideration of a different approach and a relatively new method of testing.Atterberg limits test,miniature VST,and reverse extrusion test(RET)were conducted on 120 remolded samples.The effect of soil plasticity on undrained shear strength was examined using the liquidity index instead of Bjerrum's correction factor.In comparison with the result obatined using the Bjerrum's correction factor,the lindrained shear strength was better represented when s_u values were correlated with the liquidity index.The results were validated by the RET,which was proven to take into account soil plasticity with a reliable degree of accuracy.This study also shows that the RET has strong promise as a new tool for testing undrained shear strength of fine-grained soils. | Kamil Kayabali Ozgur Akturk Mustafa Fener Orhan Dikmen Furkan Hamza Harputlugil | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，6： | 1 |

| 20 | Manufacturing size effect on the structural and mechanical properties of additively manufactured Ti-6Al-4V microbeams显示文摘The size effect of Ti-6Al-4V submillimeter structures manufactured by selective laser melting,which is critical for metallic mechanical metamaterials of unique mechanical properties,for example,nega-tive Poisson’s ratio and ultrahigh modulus,which show promise in biomedical,environmental,energy-related applications,has not been systematically investigated.Presented here are the quantification of the porosities by X-ray microtomography scans,texture analysis,and mechanical characterization of the addi-tively manufactured Ti-6Al-4V microbeams.We found linearly decreasing porosities,increasing mechan-ical properties,and increasing texture in the microbeam with increasing diameter from 250 to 500μm.The variation of microstructure in microbeams of different diameters and along the sample height,result-ing from the printing parameters and the thermal conditions,leads to the discrepancy between the be-havior observed in experiments and finite element simulation.Our results provide the structure-property-processing correlation to improve the manufacturing and prediction of the mechanical behavior of metal-lic mechanical metamaterials. | Kaiyang Yin Bo Cao Juraj Todt Florian Gutmann Hasan Furkan Tunçay Antonina Roth Frank Fischer Nadira Grübel Aron Pfaff Georg C.Ganzenmüller Jozef Keckes Stefan Hiermaier Christoph Eberl | 2023 | Journal of Materials Science & Technology2023，，18： | 0 |
