A Successful Experience of Traceability System for the Case of Yin Chuan Organic Farm in Taiwan

In Taiwan, the traceability system (TS) of whole food chain is in infantile time. Yin Chuan Organic Farm, constituted by the team of rice production and marketing (TRPM), is the first brand in Taiwan rice market. The leader of TRPM is not only to produce the premising rice quality, but also to implement the (TS) that was introduced by Taiwan government with a great result and could be a successful experience passed to other proprietors. The findings of this paper are listed as following: 1. The TS executed by the case is only emphasized on the production side that needs to build more detailed marketing side. 2. The key successful factor to get sound TS model is to have obvious purposes and system harmony.traceability system, food safety, organic food, analytic hierarchy process (AHP), Agribusiness, Food Consumption/Nutrition/Food Safety,

Adversarial Attack Based on Prediction-Correction

Deep neural networks (DNNs) are vulnerable to adversarial examples obtained by adding small perturbations to original examples. The added perturbations in existing attacks are mainly determined by the gradient of the loss function with respect to the inputs. In this paper, the close relationship between gradient-based attacks and the numerical methods for solving ordinary differential equation (ODE) is studied for the first time. Inspired by the numerical solution of ODE, a new prediction-correction (PC) based adversarial attack is proposed. In our proposed PC-based attack, some existing attack can be selected to produce a predicted example first, and then the predicted example and the current example are combined together to determine the added perturbations. The proposed method possesses good extensibility and can be applied to all available gradient-based attacks easily. Extensive experiments demonstrate that compared with the state-of-the-art gradient-based adversarial attacks, our proposed PC-based attacks have higher attack success rates, and exhibit better transferability.Comment: This manuscript was submitted to CVPR 202

catena-Poly[(dichloridozinc)-μ-bis­(pyridin-3-yl)methanone-κ2 N:N′]

In the title polymer, [ZnCl2(C11H8N2O)]n, the ZnII atom lies on a twofold rotation axis and has a distorted tetra­hedral ZnCl2N2 geometry involving two chloride donors and two N-atom donors from μ2-bridging bis­(pyridin-3-yl)methanone ligands, which also have twofold symmetry. A zigzag chain structure is formed, extending along (001). Each chain is surrounded by three others which are inter­connected through weak C=O⋯πpyrid­yl [O⋯centroid = 2.999 (3) Å] and πpyrid­yl–πpyrid­yl inter­actions [minimum ring centroid separation = 4.014 (2) Å], giving a three-dimensional framework

An Active Margin System and its Application in Chinese Margin Lending Market

In order to protect brokers from customer defaults in a volatile market, an active margin system is proposed for the transactions of margin lending in China. The probability of negative return under the condition that collaterals are liquidated in a falling market is used to measure the risk associated with margin loans, and a recursive algorithm is proposed to calculate this probability under a Markov chain model. The optimal maintenance margin ratio can be given under the constraint of the proposed risk measurement for a specified amount of initial margin. An example of such a margin system is constructed and applied to $26,800$ margin loans of 134 stocks traded on the Shanghai Stock Exchange. The empirical results indicate that the proposed method is an operational method for brokers to set margin system with a clearly specified target of risk control.Comment: 27 pages, 2 figures, 5 table

Primary Pulmonary Synovial Sarcoma: A Case Report

We report a rare case of primary synovial sarcoma of the lung. A 57-year-old man had a well-defined tumor in the right middle lobe seen on chest computed tomography, and underwent lobectomy. Grossly, the nonencapsulated tumor measured 4.5 cm in greatest diameter, with a solid and tan-white cut surface. Histologically, the tumor was mainly composed of a dense proliferation of spindle cells. Immunohistochemical studies were focally positive for epithelial membrane antigen, and diffusely positive for CD99 and Bcl-2. Cytokeratin, S-100 protein, desmin, smooth muscle actin, and CD34 were absent. SYT-SSX1 gene fusion transcript was detected by reverse transcription-polymerase chain reaction, which is diagnostic of primary synovial sarcoma of the lung. We also review the literature with regard to the clinicopathologic, immunohisto-chemical, and molecular studies of primary pulmonary synovial sarcoma

Heteroatom–doped hollow carbon microspheres based on amphiphilic supramolecular vesicles and highly crosslinked polyphosphazene for high performance supercapacitor electrode materials

Hybrid hollow polymeric microspheres (HPMSs) are synthesized by encapsulating the supramolecular vesicles with polyphosphazene through a rapid one-step polycondensation reaction. Subsequent carbonization treatments of the HPMSs lead to corresponding hollow carbon microspheres (HCMSs) with well-preserved geometry. The sizes of HPMSs and HCMSs are controlled by the vesicles, which is directly determined by the feeding ratio of the assembly units. Electrodes based on HCMSs showed a specific capacitance of 314.6 F/g at a current density of 0.2 A/g in 6 M KOH electrolyte, 180.0 F/g at a current density of 30 A/g, and high stability of 98.2% of capacity retention after 2000 cycles. Both the high surface area and high heteroatoms level of HCMSs contribute to the excellent capacitive performance. Meanwhile, the hollow carbon structure ensured the satisfactory capacitive performance by increasing utilization efficiency of the surface area as well as achieving short diffusion paths for electrolyte ions

Heritage, local communities and the safeguarding of ‘Spirit of Place’ in Taiwan

After brief reviews of the theoretical concepts relating to place and ecomuseological processes this paper traces the changing relationships between people and place in Taiwan. Research carried out by the authors with local communities on Matsu (a group of Taiwanese islands off the coast of mainland China), and case study material collected from local cultural workshops in southern Taiwan provides a focus for the discussion. Both sets of data demonstrate the growing awareness of heritage by local communities in Taiwan; they recognize that heritage is significant because it reflects and builds local identities, aids community sustainability and provides a sense of place. An account is given about how these inclusive processes are applied and how they appear to benefit the heritage sector in Taiwan. By encouraging community-centred approaches, consultation, involvement and democratization, significant improvements to safeguarding natural resources, the cultural environment and intangible cultural heritage might be possible. However, striking a balance between the aspirations of local heritage activists and the wider community is difficult to achieve
