Symmetric negative differential resistance in a molecular nanosilver chain
The electrical transport properties of the molecular nanosilver chain have been investigated. We observed the symmetric negative differential resistance (NDR) in the current-voltage characteristics. The peak voltage (V P) increased but the peak current (I P) decreased upon cooling. The self-capacitance effect of the silver chain crystal is suggested to explain this unconventional NDR phenomenon.open0
How Does Corporate Social Responsibility Promote Innovation? The Sequential Mediating Mechanism of Employeesâ Meaningfulness of Work and Intrinsic Motivation
Based on group creativity framework, our research investigates how corporate social responsibility (CSR) promotes innovation of firms by revealing sequential mediating mechanisms of employeeâs meaningfulness of work and intrinsic motivation. By applying a multi-level approach, this study examines the internal processes of micro-level variables between two macro-level variables (i.e., CSR and innovation). Utilizing a 3-wave longitudinal data from 4,178 organizational members in 502 branches as well as objective CSR records from one of the largest Korean commercial banks, we found that employeeâs meaningfulness of work and intrinsic motivation sequentially mediate the CSR-innovation link. The results suggest that CSR functions as a powerful driver of innovation through enhancing employeesâ perceptions and attitudes toward their job
The Devil in the Details: Simple and Effective Optical Flow Synthetic Data Generation
Recent work on dense optical flow has shown significant progress, primarily
in a supervised learning manner requiring a large amount of labeled data. Due
to the expensiveness of obtaining large scale real-world data, computer
graphics are typically leveraged for constructing datasets. However, there is a
common belief that synthetic-to-real domain gaps limit generalization to real
scenes. In this paper, we show that the required characteristics in an optical
flow dataset are rather simple and present a simpler synthetic data generation
method that achieves a certain level of realism with compositions of elementary
operations. With 2D motion-based datasets, we systematically analyze the
simplest yet critical factors for generating synthetic datasets. Furthermore,
we propose a novel method of utilizing occlusion masks in a supervised method
and observe that suppressing gradients on occluded regions serves as a powerful
initial state in the curriculum learning sense. The RAFT network initially
trained on our dataset outperforms the original RAFT on the two most
challenging online benchmarks, MPI Sintel and KITTI 2015
Future development strategies for KODISA journals: overview of 2016 and strategic plans for the future
Purpose â With the rise of the fourth industrial revolution, it has converged with the existing industrial revolution to give shape to increased accessibility of knowledge and information. As a result, it has become easier for scholars to actively pursue and compile research in various fields. This current study aims to focus and assess the current standing of KODISA: the Journal of Distribution Science (JDS), International Journal of Industrial Distribution & Business (IJIDB), the East Asian Journal of Business Management (EAJBM), the Journal of Asian Finance, Economics and Business (JAFEB) in a rapidly evolving era. Novel strategies for creating the future vision of KODISA 2020 will also be examined. Research design, data, and methodology â The current research will analyze published journals of KODISA in order to offer a vision for the KODISA 2020 future. In part 1, this paper will observe the current address of the KODISA journal and its overview of past achievements. Next, part 2 will discuss the activities that will be needed for journals of KODISA, JDS, IJIDB, EAJBM, JAFEB to branch out internationally and significant journals will be statistically analyzed in part 3. The last part 4 will offer strategies for the continued growth of KODISA and visions for KODISA 2020. Results â Among the KODISA publications, IJIDB was second, JDS was 23rd (in economic publications of 54 journals), and EAJBM was 22nd (out of 79 publications in management field journals). This shows the high quality of the KODISA publication journals. According to 2016 publication analysis, JDS, IJIDB, etc. each had 157 publications, 15 publications, 16 publications, and 28 publications. In the case of JDS, it showed an increase of 14% compared to last year. Additionally, JAFEB showed a significant increase of 68%. This shows that compared to other journals, it had a higher rate of paper submission. IJIDB and EAJBM did not show any significant increases. In JDS, it showed many studies related to the distribution, management of distribution, and consumer behavior. In order to increase the status of the KODISA journal to a SCI status, many more international conferences will open to increase its international recognition levels. Second, the systematic functions of the journal will be developed further to increase its stability. Third, future graduate schools will open to foster future potential leaders in this field and build a platform for innovators and leaders. Conclusions â In KODISA, JDS was first published in 1999, and has been registered in SCOPUS February 2017. Other sister publications within the KODISA are preparing for SCOPUS registration as well. KODISA journals will prepare to be an innovative journal for 2020 and the future beyond
Papillary Adenocarcinoma
Gastric papillary adenocarcinoma is one of the histological variants of gastric cancer that shows more aggressive clinicopathological behavior compared to tubular adenocarcinoma. Previous studies have reported higher lymphovascular and submucosal invasion rates for papillary adenocarcionoma than those of tubular adenocarcinoma. However, the current guidelines categorize papillary adenocarcinoma and tubular adenocarcinoma together as differentiated-type tumor and have recommended the same endoscopic submucosal dissection criteria. Thus, concerns have been raised regarding the appropriateness of the current policy. To validate the current guidelines, the lymph node metastasis rate from surgical specimen studies as well as the long-term outcomes of endoscopic submucosal dissection for papillary adenocarcinomas need to be taken into consideration. In this review, I aimed to review the current understanding of the clinical and pathological features of papillary adenocarcinoma. In addition, I aimed to generate an integrated view regarding the outcomes of endoscopic submucosal dissection and surgery for papillary adenocarcinoma in order to evaluate the appropriateness of the current guidelines

Comparison of Internal and Total Optical Aberrations for 2 Aberrometers: iTrace and OPD Scan
PURPOSE: To compare and evaluate the total and internal aberrations measured by two aberrometers: the laser ray tracing aberrometer (iTrace, Tracey Technology) and the automatic retinoscope aberrometer (OPD Scan, Nidek).
METHODS: A total of 54 healthy eyes were enrolled in the study. Following pupil dilation, aberrations were measured with the iTrace and OPD Scan. We compared the aberrations obtained from measurements obtained at pupillary diameters of 4 mm and 6 mm with the OPD Scan and iTrace. Aberrations of internal optics and total aberrations were compared for the two aberrometers. For each aberrometer and each eye, the averaged Zernike data were used to calculate various root-mean-square (RMS) data. These parameters, together with the refractive parameters, were then analyzed and complimented by paired t-tests.
RESULTS: At a pupil diameter of 4 mm, the number of total aberrations in the entire eye showed significant differences for the mean values of spherical aberrations (Z4,0) obtained with the OPD Scan and iTrace aberrometers (p=0.001). Aberrations of the internal optics showed significant differences in the mean values of total RMS, coma (Z3,-1), and trefoil (Z3,3) between the iTrace and OPD Scan (p<0.001, p=0.01, p<0.001) for the same pupil diameter of 4 mm. At a pupil diameter of 6 mm, the two instruments showed a similar number of total aberrations. Aberrations of the internal optics showed significant differences in the mean values of total RMS, spherical aberration (Z4,0), and coma (Z3,-1) between the two devices (p<0.001, p=0.01, p<0.001).
CONCLUSIONS: The iTrace and OPD Scan showed the largest number of differences for aberrations of internal optics rather than total aberrations for both pupil diameters. These results suggest that in healthy eyes, the two aberrometers may vary in some details. The aberrometers showed more agreement at a pupil diameter of 6 mm compared to 4 mmope

Biological Effect of Gas Plasma Treatment on CO 2
Porous polycaprolactone (PCL) scaffolds were fabricated by using the CO2 gas foaming/salt leaching process and then PCL scaffolds surface was treated by oxygen or nitrogen gas plasma in order to enhance the cell adhesion, spreading, and proliferation. The PCL and NaCl were mixed in the ratios of 3â:â1. The supercritical CO2 gas foaming process was carried out by solubilizing CO2 within samples at 50°C and 8âMPa for 6âhr and depressurization rate was 0.4âMPa/s. The oxygen or nitrogen plasma treated porous PCL scaffolds were prepared at discharge power 100âW and 10âmTorr for 60âs. The mean pore size of porous PCL scaffolds showed 427.89âÎŒm. The gas plasma treated porous PCL scaffolds surface showed hydrophilic property and the enhanced adhesion and proliferation of MC3T3-E1 cells comparing to untreated porous PCL scaffolds. The PCL scaffolds produced from the gas foaming/salt leaching and plasma surface treatment are suitable for potential applications in bone tissue engineering
