Designing Visceral, Behavioural and Reflective Products

Designers and manufacturers often see consumption as the primary objective of a product - with implications such as discarded products, obsolete wastes, and ecological degradation. The paper aims to find the answer to the question, how emotional design can adapt the discarded and undesirable products into something valuable in a long term? This paper presents a framework combining Chapman's theory and Norman's theory on three levels of emotional design to highlight what long lasting connection with products entails. A design approach is presented combing the Wabi Sabi philosophy that promotes the celebration of decay and damage. This is used as one of the design principles for the experiments conducted on discarded products. Through constant user interaction before, during and after the experiments the evaluation of design as an agent of transformation is done. The user conducted the evaluation based on the Kansei elements of looks, sound, smell, and feel of the product. The experiments confirmed that a long-term value is only achieved through redesigning and reconstructing the perception of people towards products on a reflective level, rather than the visceral and behavioural elements of the product. The research found attachment to the visceral and behavioural elements of a product instead of an emotional one was causing users to discard products faster than required. The research indicated that many people, including designers and manufacturers, are unconsciously focusing on usability (behavioural level) and physical look (visceral level) of a product that are easily replaced, than on a meaningful way (reflective level) to create and maintain long-lasting emotions. The research concluded with a proposition towards digitization of products which could perhaps be an all round solution to make products more appropriate to human emotions. Digitization could give products the ability to capture, store and then communicate the stories, journey and memories back, in order to empower people to understand the value of longer-term use of products.
Differentially Private Event Histogram Publication on Sequences over Graphs

The big data era is coming with strong and ever-growing demands on analyzing personal information and footprints in the cyber world. To enable such analysis without privacy leak risk, differential privacy (DP) has been quickly rising in recent years, as the first practical privacy protection model with rigorous theoretical guarantee. This paper discusses how to publish differentially private histograms on events in time series domain, with sequences of personal events over graphs with events as edges. Such individual-generated sequences commonly appear in formalized industrial workflows, online game logs, and spatial-temporal trajectories. Directly publishing the statistics of sequences may compromise personal privacy. While existing DP mechanisms mainly target at normalized domains with fixed and aligned dimensions, our problem raises new challenges when the sequences could follow arbitrary paths on the graph. To tackle the problem, we reformulate the problem with a three-step framework, which 1) carefully truncates the original sequences, trading off errors introduced by the truncation with those introduced by the noise added to guarantee privacy, 2) decomposes the event graph into path sub-domains based on a group of event pivots, and 3) employs a deeply optimized tree-based histogram construction approach for each sub-domain to benefit with less noise addition. We present a careful analysis on our framework to support thorough optimizations over each step of the framework, and verify the huge improvements of our proposals over state-of-the-art solutions.

Urban air quality, meteorology and traffic linkages: Evidence from a sixteen-day particulate matter pollution event in December 2015, Beijing

A heavy 16-day pollution episode occurred in Beijing from December 19, 2015 to January 3, 2016. The mean daily AQI and PM_(2.5) were 240.44 and 203.6 μg/m~3. We analyzed the spatiotemporal characteristics of air pollutants, meteorology and road space speed during this period, then extended to reveal the combined effects of traffic restrictions and meteorology on urban air quality with observational data and a multivariate mutual information model. Results of spatiotemporal analysis showed that five pollution stages were identified with remarkable variation patterns based on evolution of PM_(2.5) concentration and weather conditions. Southern sites (DX, YDM and DS) experienced heavier pollution than northern ones (DL, CP and WL). Stage P2 exhibited combined functions of meteorology and traffic restrictions which were delayed peak-clipping effects on PM_(2.5). Mutual information values of Air quality-Traffic-Meteorology (ATM-MI) revealed that additive functions of traffic restrictions, suitable relative humidity and temperature were more effective on the removal of fine particles and CO than NO_2.

Diagnostic evaluation of patients with disorders of consciousness with diffusion tensor imaging

Background: With the development of emergency and intensive medical technologies, the survival rate of traumatic brain injury has greatly increased. More and more patients have been converted from severe coma to alleviated state of consciousness, which can be subsequently classified within the framework of disorders of consciousness (DOC). We investigated the clinical application and characteristics of imaging indicators of diffusion tensor imaging (DTI) for the DOC patients. Methods: DTI was performed on a total of 75 cases with a clinical diagnosis of DOC from January 2014 to December 2015 in Beijing Tiantan Hospital and PLA Army General Hospital (including 66 cases of unresponsive wakefulness state (UWS) patients and 9 cases of minimally conscious state (MCS) patients). The data for the imaging indicators, such as fractional anisotropy (FA) and mean diffusivity (MD), were separately collected from three relevant regions of interest (ROIs): brainstem, thalamus, and subcortex. The indicators of two groups with different conscious states were statistically analyzed, and correlation analyses were conducted for the mean values of FA and MD in the ROIs evaluated through clinical Coma Recovery Scale-Revised (CRS-R) scores. Results: The FA value of the UWS group was evidentially lower than that of the MCS group (P < 0.05), while the MD value of the UWS group was higher than that of the MCS group (P < 0.05); the difference was statistically significant. The FA and MD values in the ROIs (locations: brainstem, thalamus, and subcortex) correlated with CRS-R scores, particularly in the thalamus. Conclusion: DTI has a certain clinical reference value for DOC imaging grading. The more severe the DOC, the higher the MD value and the lower the FA value.
Topology of unitary groups and the prime orders of binomial coefficients

Let c: SU(n) → PSU(n) = SU(n)/ Z_n be the quotient map of the special unitary group SU(n) by its center subgroup Z_n. We determine the induced homomorphism c~?: H~?(PSU(n)) → H~?(SU(n)) on cohomologies by computing with the prime orders of binomial coefficients.
A magnetic bald-patch flare in solar active region 11117

With SDO observations and a data-constrained magnetohydrodynamics (MHD) model, we identify a confined multi-ribbon flare that occurred on 2010 October 25 in solar active region 11117 as a magnetic bald patch (BP) flare with strong evidence. From the photospheric magnetic field observed by SDO/HMI, we find there are indeed magnetic BPs on the polarity inversion lines (PILs) which match parts of the flare ribbons. From the 3D coronal magnetic field derived from an MHD relaxation model constrained by the vector magnetograms, we find strikingly good agreement of the BP separatrix surface (BPSS) footpointswith the flare ribbons, and the BPSS itself with the hot flaring loop system.Moreover, the triggering of the BP flare can be attributed to a small flux emergence under the lobe of the BPSS, and the relevant change of coronal magnetic field through the flare is reproduced well by the pre-flare and post-flare MHD solutions, which match the corresponding pre- and post-flare AIA observations, respectively. Our work contributes to the study of non-typical flares that constitute the majority of solar flares but which cannot be explained by the standard flare model.
Enhancement of Growth and Grain Yield of Rice in Nutrient Deficient Soils by Rice Probiotic Bacteria

Plant associated bacteria are promising alternatives to chemical fertilizers for plant growth and yield improvement in an eco-friendly manner. In this study, rice associated bacteria were isolated and assessed for mineral phosphate solubilization and indole-3-acetic acid (IAA) production activity in vitro. Six promising strains, which were tentatively identified as phylotaxon Pseudochrobactrum sp. (BRRh-1), Burkholderia sp. (BRRh-2), Burkholderia sp. (BRRh-3), Burkholderia sp. (BRRh-4), Pseudomonas aeruginosa (BRRh-5 and BRRh-6) based on their 16S rRNA gene phylogeny, exhibited significant phosphate solubilizing activity in National Botanical Research Institute phosphate growth medium, and BRRh-4 displayed the highest phosphate solubilizing activity, followed by BRRh-5. The pH of the culture broth declined, resulting in increase of growth rate of bacteria at pH 7,which might be due to organic acid secretion by the strains. In presence of L-tryptophan, five isolates synthesized IAA and the maximum IAA was produced by BRRh-2, followed by BRRh-1. Application of two most efficient phosphate solubilizing isolates BRRh-4 and BRRh-5 by root dipping (colonization) of seedling and spraying at the flowering stage significantly enhanced the growth and grain yield of rice variety BRRI dhan-29. Interestingly, application of both strains with 50% of recommended nitrogen, phosphorus and potassium fertilizers produced equivalent or higher grain yield of rice compared to the control grown with full recommended fertilizer doses, which suggests that these strains may have the potential to be used as bioinoculants for sustainable rice production.
Screening for Osmotic Stress Responses in Rice Varieties under Drought Condition

Drought is the major abiotic stress factor that limits rice production worldwide. To evaluate the osmotic stress responses in rice varieties under drought condition, a total of 42 high-yielding rice varieties were collected from various research stations of Kerala Agricultural University in India. The experimental setup comprises of initial hydroponic treatments at different osmotic potentials, artificially induced by desired strengths of polyethylene glycol (PEG6000), and followed by the pot planted experiments in the rain-out-zone. The activities of antioxidant enzymes, relative water content, cell membrane stability, photosynthetic pigments, proline content, along with plant growth parameters of the varieties under drought condition were evaluated. Moreover, the standard scores of these rice varieties were assessed under stress and recovery conditions based on the scoring scale of the Standard Evaluation System for rice. Among the 42 rice varieties, we identified 2 rice varieties, Swarnaprabha and Kattamodan, with less leaf rolling, better drought recovery ability as well as relative water content, increased membrane stability index, osmolyte accumulation, and antioxidant enzyme activities pointed towards their degree of tolerance to drought stress. The positive adaptive responses of these rice varieties towards drought stress can be used in the genetic improvement of rice drought resistance breeding program.

Three-dimensional free view reconstruction in axially distributed image sensing

In this Letter, we propose a three-dimensional (3D) free view reconstruction technique in axially distributed image sensing (ADS). In typical integral imaging, free view reconstructed images can be obtained by tilting all elemental images or tilting the reconstruction plane due to large lateral perspectives for 3D objects. In conventional ADS, the reconstructed images at only a front view can be generated since the sensor is moved along with its optical axis so that it has small lateral perspectives for 3D objects. However, the reconstructed 3D images at any viewing point may be obtained because the virtual viewing cameramay capture these slightly different perspectives for 3D objects. Therefore, in this Letter, we employ the virtual viewing camera to visualize the 3D images at the arbitrary viewing point. To support our proposed method, we show the experimental results.

Transformation Mechanism of (γ + γ') and the Effect of Cooling Rate on the Final Solidification of U720Li Alloy

The transformation mechanism of (γ + γ') was studied by analyzing the microstructure and elemental distribution of the U720Li samples heated at 1250 °C and cooled at the rates in the range of 1-100 °C/s. Although the (γ + γ') is deemed to be formed by a eutectic reaction and has been called eutectic (γ + γ'),it was found in the present study that the (γ + γ) precipitation begins with a peritectic reaction of (L + γ) → γ',and develops by the eutectic reaction of L → (γ + γ'). The energy for the γ' nucleation is low because the interfacial energy for the γ/γ' interface is about one-tenth of the solid/liquid interface, and hence, the nucleation rate is high and the fine structure of (γ + γ') is formed at the initial precipitation stage. The γ and γ' in (γ + γ') tend to grow into a lamellar structure because it is difficult for them to nucleate directly from the residual liquids, and hence, the γ' precipitates naturally tend to grow divergently direction of the regions rich in Al and Ti, forming a fan-like structure of the (γ + γ'). As a result, the γ' precipitates will coarsen finally because the space between them is enlarged. The solidification of the final residual liquids is a diffusion dependent process. When cooled at a higher rate, a higher degree of super cooling is reached and finally the solidification is finished by the pseudo-eutectic reaction of L → (γ + boride) and L → (γ + η), which can absorb Zr and B. When cooled at a rate low enough,most of the residual liquids are consumed by the (γ + γ') growth due to the sufficient diffusion, and the boride and Zrbearing phase are precipitated at a quasi-equilibrium state. Under this condition, Ti is depleted at the (γ + γ') growth front. However, the η-Ni_3Ti phase is formed there occasionally due to the boride precipitation, because the compositions of the two phases are complementary.
Copper oxide nanoparticles-loaded zeolite and its characteristics and antibacterial activities

In the present work, a simple and green co-precipitation method was used to prepare copper oxide-zeolite nanocomposites (CuO-zeolite NCs). The weight ratio (1, 3, 5, 8 and 10 wt%) of CuO nanoparticles (NPs) loaded into zeolite was investigated to obtain the optimum CuO distribution for antibacterial activities. The prepared CuO-zeolite NCs were characterized by ultraviolet-visible (UV–vis) spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, powder X-ray diffraction (XRD), and energy dispersive X-ray fluorescence spectrometry (EDXRF). The transmission electron microscopy (TEM) and field emission scanning electron microscopy (FE-SEM) revealed a uniform surface morphology of the CuO-zeolite NCs. The UV–vis spectrum of NCs showed absorption peaks between 230 and 280nm for nano-CuO in the XRD patterns, and new peaks appeared between (36.56?–38.83?) related to the CuO. At weight ratio less than 10 wt%, the CuO nanoparticles loaded to the zeolite exhibited spherical shapes with average particle diameter of 6.5nmmeasured byTEMand XRD. Antibacterial activities were tested against Gram-negative and Gram-positive bacteria. The obtained results showed that, CuO-zeolite NCs with 8 wt% CuO nanoparticles had the highest antibacterial activities against Bacillus Subtilis B29 and Salmonella Choleraesuis ATCC 10708, which can be attributed to the good dispersion of CuO NPs on the zeolite surface.
Molten Salt Electrolytic Fabrication of TiC-CDC and Its Applications for Supercapacitor

Titanium carbide derived carbon (TiC-CDC) was prepared by the molten salt electrolytic method in molten salt NaCl–KCl at the potential of 1.3V using TiC pellets as the anode. X-ray diffraction, scanning electron microscopy and Raman spectrum were used to characterize the composition, morphology and microstructure of TiC-CDC. The electrochemical performance of TiC-CDC for supercapacitor was investigated in 0.5 mol L~(–1) Na_2SO_4 by cycle voltammograms, ac impedance spectrum and galvanostatic charge/discharge. TiC-CDC showed excellent electrochemical and capacitive performances and maintained a capacity value of 126.1 F g~(–1) after 1000 cycles with a capacity retention rate of 97% at the current density of 3Ag~(–1). The current work demonstrated the feasibility of molten salt electrolytic method for preparation of TiC-CDC and provided a non-polluting and environmentally friendly strategy for high performance supercapacitor fabrication.
低强度脉冲超声介导骨髓间充质干细胞移植的研究进展

骨髓间充质干细胞(bone marrow mesenchymal stem cell, BM-MSCs)是一种源于骨髓具有跨系统、跨胚层分化潜能及高度自我更新能力的成体干细胞,其取材方便,免疫排异反应小,易于外源基因的转染和表达,这些特点较目前其他种类的干细胞更具优势,成为细胞治疗领域中的理想工具。但BM-MSCs在实际应用中仍存在增殖及分化效率低、趋化归巢到靶器官细胞数量少等缺陷。近年来研究发现,低强度脉冲超声(low intensity pulsed ultrasound, LIPUS)能够在体内外促进BM-MSCs的增殖活性、定向分化及趋化归巢能力,显示出这种技术在干细胞移植应用的潜力,本文就LIPUS介导BM-MSCs移植的研究进行综述。

Characterization of Air Pollution in Urban Areas of Yangtze River Delta, China

The hallmark of development in the Yangtze River Delta (YRD) of East China has been sprawling urbanization. However, air pollution is a significant problem in these urban areas. In this paper, we investigated and analyzed the air pollution index (API) in four cities (Shanghai, Nanjing, Hangzhou and Ningbo) in the YRD from 2001 to 2012. We attempted to empirically examine the relationship between meteorological factors and air quality in the urban areas of the YRD. According to the monitoring data, the API in Shanghai, Nanjing, Hangzhou slightly declined and that in Ningbo increased over the study period. We analyzed the inter-annual, seasonal, and monthly variations of API, from which we found that the air quality had different temporal changes in the four cities. It was indicated that air quality was poor in winter and spring and best in summer. Furthermore, different weather conditions affected air quality level. The wind direction was considered as an important and influential factor to air pollution, which has an impact on the accumulating or cleaning processes of pollutants. The air quality was influenced by the different wind directions that varied with seasons and cities.
Impacts of Park Landscape Structure on Thermal Environment Using QuickBird and Landsat Images

Urban parks composed mostly of vegetation and water bodies can effectively mitigate the urban heat island effect. Many studies have investigated the cooling effects of urban parks; however, little attention has been given to park landscape structure. Based on landscape metrics, this study has explored the influences of the park landscape structure on its inner thermal environment, taking heavily urbanized Beijing Municipality in China as the study area. Three indices, including the percentage of landscape (PLAND), landscape shape index (LSI) and aggregation index (AI), were used to measure the composition and configuration characteristics of the landscape components inside the parks. The indices were calculated for five landscape types being interpreted from Quickbird images. Urban thermal conditions were measured using the land surface temperature (LST) derived from Landsat TM images. The results showed that the park LST had a negative relationship with the park size, but no significant relationship was found with park shape. For the park's interior landscape, however, the configuration and composition characteristics of the landscape components inside the park explained 70% of the park LST variance. The area percentage of water bodies and the aggregation index of woodland were identified as the key influencing characteristics. In addition, when the composition and configuration characteristics of the park landscape components were separately considered, the configuration characteristics (LSI and AI) explained approximately 54% of the variance in park LST, which was comparable with that explained by the composition characteristics (PLAND). Thus, this study suggested that an effective and practical way for urban cooling park design is the optimization of spatial configuration of landscape components inside the park.
Spatial Structural Pattern and Vulnerability of China-Japan-Korea Shipping Network

The economies of China-Japan-Korea (CJK) are complementary, with their proximity resulting in the three countries having a high degree of interdependence with respect to trade. Currently, trade among these countries relies mainly on port-centered shipping. The development of the shipping network is integral for in-depth integration of CJK trade. This paper analyzes the overall characteristics, centrality, spatial structure, and vulnerability of the CJK shipping network using the methods of complex network analysis, blocking flow theory, and interruption and deletion of hub ports. The main findings are as follows: 1) The CJK shipping network has a small average path length and clustering coefficient, and its degree distribution follows a power-law distribution, which make the network present obvious characteristics of a Barabasi-Albert scale-free. 2) The characteristics of the multi-center point of the CJK shipping network can alleviate traffic pressure. At the same time, the network shows a clear hierarchy in the port transportation system, with cargo transport relying mainly on the ‘hub port-hub port' connection. 3) The CJK shipping network is relatively stable. Compared with ports in Japan and Korea, the main hub ports in China have a greater impact on the stability of the shipping network, in particular those ports of the central coastal region, including Shanghai, Ningbo, and Lianyungang.
