Organic light-emitting devices (OLEDs) have attracted a lot of attention as a next generation display. In this study, we fabricated the micro-OLEDs by room-temperature curing nanoimprint lithography (RTC-NIL) using diamond molds. The diamond has superior durability and was used as mold material for RTC-NIL. The diamond molds have been fabricated by electron cyclotron resonance (ECR) oxygen ion shower with polysiloxane oxide mask in the electron beam (EB) lithography technology. We fabricated the diamond mold pattern with 10 µm-square dot. The diamond molds have been used to form an insulating layer in micro-OLEDs. The optimum thickness of N,N’-Diphenyl-N,N’-di(m-tolyl)benzidine (TPD) [hole transport layer], Tris(8-quinolinolato)aluminum (Alq3) [electron transport layer] and aluminum (Al) [cathode] were 40 nm, 40 nm and 200 nm, respectively. We succeeded in formation of insulating layer in micro-OLEDs and operation of micro-OLEDs with 10 µm-square-dot by RTC-NIL using diamond molds.

Parkinson's disease (PD) is a common movement disorder caused from the neurological dysfunction in basal ganglia. Patients with Parkinson's disease have serious movement problems, such as movement disorders, tremor and rigidity. In this study, a new technique of hand movement compensation for patients with Parkinson's disease based on spiral drawing tasks was proposed. In order to extract the hand movement feature of patients with Parkinson's disease, the polar coordination system with varied origin was used to gain characteristic parameters more accurately. The compensation model was constructed by using the parameters obtained in spiral drawing tasks, and we also do simulation under this model to verify the effectiveness. The simulation results proved that the proposed compensation technique will be effective for assisting the movement of patients with Parkinson's disease.

Parkinson's disease (PD) is a common disease of central nervous system among the elderly, and its complex symptoms bring up some difficulties for the clinical diagnosis. And Deep Brain Stimulation (DBS) is an effective treatment method for patients with Parkinson's disease. In this study, a method based on polar coordination system with varied origin was proposed to quantitatively evaluate the availability of DBS operation for patients with Parkinson's disease. Totally, seven patients with Parkinson's disease were participated in the spiral drawing experiment and their scores under Unified Parkinson's disease Rating Scale (UPDRS) were also recorded. According to the characteristics of hand movement in spiral drawing, a set of parameters were defined and calculated before and after DBS operation. Compared with the UPDRS scores, experimental results showed that this method of evaluation was consistent with the clinical diagnosis. The proposed method based on polar coordinate system with varied origin is effective in clinical diagnosis, and it provides a basis for quantitative evaluating the effectiveness of surgery and treatment.

Parkinson's disease is one of the most common neurodegenerative disorders, and its complex symptoms bring some difficulties for the clinical diagnosis. In this study, a method based on mathematical modeling of hand movement in spiral drawing was proposed to quantitatively evaluate the performance of patients with Parkinson's disease. Unlike the previous works, the hand movement data in spiral drawing were analyzed and modeled under the polar coordinate system with varied origin. Experimental results gained from the model showed that this method of evaluation was consistent with the clinical diagnosis before and after deep brain stimulation operation. The proposed method based on mathematical modeling in polar coordinate system with varied origin is effective in clinical diagnosis, and it provides a basis for quantitative evaluating the effectiveness of surgery and treatment.

We have investigated the nanopatterning of chemical vapor deposited (CVD) diamond films in room-temperature nanoimprint lithography (RT-NIL), using a diamond nanodot mold. We have proposed the use of polysiloxane as an electron beam (EB) mask and RT-imprint resist materials. The diamond molds of cylinder dot using the RT-NIL process were fabricated with polysiloxane oxide mask in EB lithography technology. The dot in minimum diameter is 500 nm. The pitch between the dots is 2 μm, and dot has a height of about 600 nm. It was found that the optimum imprinting conditions for the RT-NIL : time from spin-coating to imprinting t1 of 1 min , pressure time t2 of 5 min, imprinting pressure P of 0.5 MPa. The imprint depth obtained after the press under their conditions was 500 nm. We carried out the RT-NIL process for the fabrication of diamond nanopit arrays, using the diamond nanodot molds that we developed. The resulting diamond nanopit arrays with 500 nm-diameter and 200 nm-depth after the electron cyclotron resonance (ECR) oxygen ion beam etching were fabricated. The diameter of diamond nanopit arrays was in good agreement with that of the diamond nanodot mold. © 2011 Materials Research Society.

We have proposed the use of glass-like carbon (GC), as mold material because the 27-maximum etching selectivity of polysiloxane film against GC, which was approximately six times larger than that of polysiloxane film against chemical vapor deposited (CVD) diamond film. We have investigated the fabrication of diamond nanopit arrays by room-temperature curing nanoimprint lithography (RTC-NIL) using GC mold, as applications to the emitter and the micro-gear. The polysiloxane has in the state of sticky liquid at room-temperature and negative-exposure characteristic. Therefore, the polysiloxane was used as RTC-imprint resist material, and also used as electron beam (EB) resist (oxide mask) material in EB lithography. We have fabricated the cylindrical GC nanodot mold with 500 nm-diameter, 600 nm-height and 2 µm-pitch. We carried out RTC-NIL using GC mold under the following optimum conditions: time from spin-coating to imprint of 1 min, imprinting pressure of 0.5 MPa and imprinting time of 5 min. Then, we have processed the diamond film with an electron cyclotron resonance (ECR) oxygen ion shower. We have fabricated diamond nanopit array with 250 nm-depth and 500 nm-diameter. The diameter of diamond nanopit pattern was in good agreement with that of GC mold. Moreover, the depth of the diamond nanopit patterns fabricated by RTC-NIL using cylindrical GC mold was three times larger than that using conical diamond mold.

In this study, a new type of trigonometric neural network is presented by adding frequency and phase to trigonometric activation functions. The proposed trigonometric neural network has more flexibility in comparison with conventional trigonometric neural networks and even other types of neural networks. Due to the low convergence rate and high posibility of trapping in a local minimum of backpropagation algorithm, Extended Kalman Filter algorithm is used to train the neural network's parameters which they appear in a nonlinear form. The Simulation of the suggested neural network based on the prediction of Mackey-Glass time series and identification of a nonlinear dynamic ystem reveals the efficiency of the proposed network. To show the efficiency of this method, the results are compared with the results of the others.

In this study, a new type of training the adaptive network-based fuzzy inference system (ANFIS) is presented by applying different types of the Differential Evolution branches. The TSK-type consequent part is a linear model of exogenous inputs. The consequent part parameters are learned by a gradient descent algorithm. The antecedent fuzzy sets are learned by basic differential evolution (DE/rand/1/bin) and then with some modifications in it. This method is applied to identification of the nonlinear dynamic system, prediction of the chaotic signal under both noise-free and noisy conditions and simulation of the two-dimensional function. Instead of DE/rand/1/bin, this paper suggests the complex type (DE/current-to-best/1+1/bin & DE/rand/1/bin) on predicting of Mackey-glass time series and identification of a nonlinear dynamic system revealing the efficiency of proposed structure. Finally, the method is compared with pure ANFIS to show the efficiency of this method.
