Creative Entrances to Co-Design: Exploring Collaboration through Fiction, Fairy tales, and Games

Design fiction, storytelling, and games provide creative entrances to co-design activities with different groups. These have emerged from a need to develop joint perspectives, a joint language and technological imagination as prerequisites for participatory approaches and co-design. For this workshop, we invite researchers, practitioners and designers who are working in settings that are socially and culturally diverse, who bring together people of a broad age range and who have tried creative approaches in their co-design activities. Working in groups to co-design and further develop creative entrances, this workshop will explore and reflect upon the potential of design fiction, storytelling, and games to foster creativity in co-design activities and to support (technological) imagination. As a result, we plan to co-host together with the participants a digital exhibition with the results of the workshop.
Reconstruction of Artifacts from Digital Image Repositories

The U.S. Patent Office maintains an archive of cultural artifacts of both ornamental and functional designs. Design patents protect “any new, original, and ornamental design for an article of manufacture” [23] such as busts, statues, and the shape or configuration of any article of manufacture. The Patent Office archive originally contained both drawings and models as an effort to preserve a chronological history of the science and culture of the United States. This collection was devastated by two fires in 1836 and 1877, which destroyed or damaged more than 100,000 patent models. The Patent Office began divesting its collection in 1908, and Congress ultimately chose to dissolve the collection in 1926. A total of 10,000 of the original models are preserved in the collections of the Smithsonian National Museum of American History in Washington, D.C., and another 5,000 are preserved in the collections of the Hagley Museum and Library in Wilmington, Delaware. Although most of the physical artifacts no longer exist, documents describing the original physical models remain. These documents show each artifact as a collection of multiple black and white images depicting the artifact from different views. We propose an algorithm to reconstruct 3D point cloud models of the original artifacts from multiview images collected directly from the Patent Office archives. The use of 3D point cloud models allows both local and global geometric properties of the artifact to be described in a single vector representation. This vector representation of the artifact may be used individually or in combination with other descriptors for retrieval and classification tasks. For collections that are unclassified or where differing classification systems are used, these vector representations allow clustering of artifacts into meaningful groupings.
Experimental study of the dispersion of a ﬁre suppression agent through a real size nozzle of an aircraft cargo cabin extinguisher system

Most of active ﬁre suppression systems consist on injecting an agent into the volume set on ﬁre. In the case of aircraft cargo cabin, the agent used up to date is Halon 1301. In fact, the current level of safety, according to the FAA, is that provided by a volumetric concentration of 6% Halon 1301 throughout a protected ﬁre zone for a duration of 0.5 seconds. However, Halon 1301 is known to contribute to the depletion of Earth’s atmospheric ozone layer, and it is going to be ban in the incoming years. The FAA has already deﬁned an equivalent level of safety in terms of the performance (concentration and spatial distribution) of the alternative agent. In this work, two different alternative agents are tested. An injection system has been assembled in order to control the injection pressure and the injection duration, in other words, the agent injected mass. The discharge volume is a rectangular constant volume constant pressure vessel of approximately 0 . 85m 3 . This vessel is provided with two consecutive transparent windows of 0 . 75 × 0 . 75 m in order to ensure optical access to the whole injection and mixing process. Liquid phase distribution of the agent inside the vessel is measured by means of Diffuse Back-light Illumination (DBI) technique. Vapor phase distribution, when present, is measured through the single-pass Schlieren technique. Results show a poor performance in terms of spatial distribution of the two alternative agents. The sprays result in narrow jet with little atomization: small cone angle and fast penetration rate. This occurs mainly due to the different thermodynamic properties of these two ﬂuids compared to Halon 1301. Changes in the injection system nozzles need to be done to improve the ﬁre suppression agent
Capital Structure and Firms Profitability: The Case of Emerging Financial Sector

: This study investigates the effect and nature of relationship capital structure has on financial performance of firms in Nigerian pension industry which is the most recent development in Nigeria's financial sector. The population of the study are filtered to obtain 16 PFAs licensed by the PenCom. The study employs unbalance panel data of 80 observations which are drawn from sixteen Pension Funds Administrators from 2007 to 2012. The empirical result based on the 16 PFAs shows that long term liability have significant positive impact on ROE while short term liability have significant negative impact on ROE. Though long term liability is shown to have positive impact on ROA, the result is however not significant. it is also found that most of the firms in the Nigerian pension industry use zero leverage and this limit the chance of each of the firm to expand their earnings. It is concluded that firms in the pension industry underperform due to their inability to use long term debt in their capital structures. Finally, it is recommended PFAs should use debt in their capital structure so as to enhance their performances.

Design and Evaluation of Distributed Electric Drive Architectures for High-Lift Control Systems

High-lift control systems of commercial transport aircraft increase lift during low speed phases and keep the landing speed in reasonable limits. Today’s high-lift control systems consist of leading and trailing-edge devices which are actuated over established mechanical transmission shafts driven by central power control units. With the ongoing trend of more-electric aircraft and potential benefits by functional enhancement of the flight control system, new possibilities arise for future high-lift system architectures. One promising approach is a distributed electric drive architecture. This provides the opportunity to enable advanced high-lift control systems with multifunctional control surfaces driven by electrical actuators. In this contribution, a conventional high-lift system architecture - which serves as a reference system – and three distributed system architectures using electrical actuators are developed. The trailing-edge actuation system has been chosen as a representative example for this study. The system architectures are developed in an iterative design process to fulfill the high-lift system requirements, and comply with the safety regulations. Furthermore, the system masses and operating costs are estimated to evaluate the different system architectures. Finally, it can be stated, that distributed system architectures show advantages regarding overall system mass and direct operating costs compared to the conventional, reference system architecture.
Novel Design of Broad Band Microstrip Antenna for WiMAX/WLAN/UMTS Applications

Abstract The main aim of this paper is to obtain a large bandwidth with a low-cost and compact-sized antenna. Here a rectangular patch fed with linefeed technique is designed. Wide bandwidth is obtained covering the range from 0.99 – 2.68 GHz. The designed line-fed patch antenna can operate in the WiMAX (2.2 – 3.4 GHz), WLAN (2.40 – 2.48 GHz) and UMTS II (2.50 – 2.69 GHz) frequency bands giving a maximum bandwidth of 90.18%. The simulation results were carried out by the Zeland IE3D software. Keywords: Linefeed, wideband, WLAN, UMTS * Author for Correspondence E-mail: kuldeep.parashar10@gmail.com INTRODUCTION Advances in the design and production of electronic devices have enabled the development of miniaturized computer peripherals with very high performances in terms of both storage and communication rate. Hence, modern wireless systems are placing greater emphasis on antenna designs for future development in communication technology. Microstrip patch antennas are increasing in popularity for use in wireless applications due to their conformal and planar structure, compactness, low-profile, directive with high transmission efficiency, light weight, low profile, low cost and ease of integration with microwave circuit and portable communication equipment [1–3]. The size reduction with the gain and bandwidth enhancement is the major design consideration for most practical applications of microstrip antennas for wireless communication. Numerous techniques have been presented to enhance bandwidth for various communication systems. Linefeed is widely used because it is very simple to design, analyze and very easy to manufacture. [4–12]. Hence linefeed is used in the planar rectangular structure of the proposed antenna. The height of the patch is kept more and dielectric constant of the substrate is less for wide bandwidth, better gain and directivity. While the bandwidth and the size of an antenna are generally mutually conflicting properties, that is, improvement of one of the characteristics normally results in degradation of the other. In this paper, a novel line feed patch antenna is investigated for the gain and bandwidth enhancement with compact size. The proposed antenna has been designed on glass epoxy substrate to give a wide bandwidth of 90.18% and maximum radiating efficiency of about 99% which is well suitable for WiMAX, WLAN and UMTS wireless applications.
Physics Object Localization with Point Cloud Segmentation Networks

In modern particle physics experiments, the identiﬁcation and trajectory of physics object, e.g. leptons and jets, depends on a complex pipeline of feature extraction, search, and machine learning algorithms. Deep neural networks (DNNs) oﬀer a possibility of streamlining this process. This note describes the production of a dataset that the ATLAS collaboration is releasing for community use. It is formatted like popular point-cloud datasets, e
Addressing temporal considerations in life cycle assessment of the Total Environment

suchtemporalconsiderationshas previ-ouslybeenunderlinedasanimportantsourceofuncertainty,butagrowingnumberofapproacheshavebeende- veloped to tackle this issue. Nevertheless, their adoption by LCA practitioners is still uncommon, which raises concernsabout the representativeness ofcurrentLCAresults.Furthermore, a lack of consistencycanbeobserved in the used terms for discussions on temporal considerations. The purpose of this review is thus to search for common ground and to identify the current implementation challenges while also proposing development pathways. This paper introduces a glossary of the most frequently used terms related to temporal considerations in LCA to build a common understanding of key concepts and to facilitate discussions. A review is also performed on current solutionsfor temporal considerationsindifferentLCA phases(goal and scope de ﬁ nition, life cycleinventory analysis and life cycleimpact assessment), analysing eachtemporal consideration for its relevant conceptual developments in LCA and its level of operationalisation. We then present a potential stepwise approach and development pathways to address the current challenges of implementation for dynamic LCA (DLCA). Three key focal areas for integrating temporal considerations within the LCA framework are discussed: i) de ﬁ ne the temporal scope over which temporal distributions of emissions
Pharmacological Evaluation of the Libyan Folk Herb Retama Raetam Seeds in Mice

: Retama raetam (RR) is a traditional medicinal plant belongs to fabaceae family which grows in North Africa and East Mediterranean region. Locally, RR is used in several diseases including diabetes mellitus and hypertension. Thus, this study aims to investigate certain behavioral and central effects of methanolic extract of RR seeds in experimental animals (male Albino adult mice of 20 – 35 gm). Three exploratory behavioral models are used in this study, open field, elevated plus maze and light-dark box models, in addition, picrotoxin induced seizure model in mice. In elevated plus-maze test of anxiety, a dose of 25 mg/kg of RR induced a significant increase in number of open arms entries and time spent on open arms of the maze compared to the control. In light-dark model, time spent on light area and number of light-dark transitions are significantly increased after treatment with 25 mg/kg RR extract of seeds. Open field model also revealed a significant increase in general motor activity of the mouse after 25 mg/kg of RR. On the other hand, a dose of 50 mg/kg of RR significantly induced a profound central and peripheral analgesic responses. In summary, this study concludes that RR seeds have a profound anxiolytic-like effect and analgesic response with delay in latency time of seizure induced by picrotoxin in mice.
Increased Protein Kinase C Activity and Expression of Ca 2 (cid:49) -Sensitive Isoforms in the Failing Human Heart

Background —Increased expression of Ca 2 (cid:49) -sensitive protein kinase C (PKC) isoforms may be important markers of heart failure. Our aim was to determine the relative expression of PKC- (cid:98) 1, - (cid:98) 2, and - (cid:97) in failed and nonfailed myocardium. Methods and Results —Explanted hearts of patients in whom dilated cardiomyopathy or ischemic cardiomyopathy was diagnosed were examined for PKC isoform content by Western blot, immunohistochemistry, enzymatic activity, and in situ hybridization and compared with nonfailed left ventricle. Quantitative immunoblotting revealed significant increases of (cid:46) 40% in PKC- (cid:98) 1 ( P (cid:44) 0.05) and - (cid:98) 2 ( P (cid:44) 0.04) membrane expression in failed hearts compared with nonfailed; PKC- (cid:97) expression was significantly elevated by 70% in membrane fractions ( P (cid:44) 0.03). PKC- (cid:101) expression was not significantly changed. In failed left ventricle, PKC- (cid:98) 1 and - (cid:98) 2 immunostaining was intense throughout myocytes, compared with slight, scattered staining in nonfailed myocytes. PKC- (cid:97) immunostaining was also more evident in cardiomyocytes from failed hearts with staining primarily localized to intercalated disks. In situ hybridization revealed increased PKC- (cid:98) 1 and - (cid:98) 2 mRNA expression in cardiomyocytes of failed heart tissue. PKC activity was significantly increased in membrane fractions from failed hearts compared with nonfailed (1021 (cid:54) 189 versus 261 (cid:54) 89 pmol (cid:122) mg (cid:50) 1 (cid:122) min (cid:50) 1 , P (cid:44) 0.01). LY333531, a selective PKC- (cid:98) inhibitor, significantly decreased PKC activity in membrane fractions from failed hearts by 209 pmol (cid:122) min (cid:50) 1 (cid:122) mg (cid:50) 1 (versus 42.5 pmol (cid:122) min (cid:50) 1 (cid:122) mg (cid:50) 1 in nonfailed, P (cid:44) 0.04), indicating a greater contribution of PKC- (cid:98) to total PKC activity in failed hearts. Conclusions failed human heart, PKC- (cid:98) 1 and - (cid:98) 2 expression and contribution to total PKC activity are significantly increased. This may signal a role for Ca 2 (cid:49) -sensitive PKC isoforms in cardiac mechanisms involved in heart failure. ( Circulation 1999;99:384-391.)
factors associated with bulk tank total bacterial count in irish dairy herds during

Research has shown that total bacterial count (TBC), which is the bacterial growth per ml of milk over a fixed period of time, can be decreased by good hygiene and farm management practices. The objective of the current study was to quantify the associations between herd management factors and bulk tank TBC in Irish spring calving, grass-based dairy herds. The relationship between bulk tank TBC and farm management and infrastructure was examined using data from 400 randomly selected Irish dairy farms where the basal diet was grazed grass. Herd management factors associated with bulk tank TBC were identified using linear models with herd annual total bacterial score (i.e., arithmetic mean of the natural logarithm of bulk tank TBC) included as the dependent variable. All herd management factors were individually analysed in a separate regression model, that included an adjustment for geographical location of the farm. A multiple stepwise regression model was subsequently developed. Median bulk tank TBC for the sample herds was 18,483 cells/ml ranging from 10,441 to 130,458 cells/ml. Results from the multivariate analysis indicated that the following management practices were associated with low TBC; use of heated water in the milking parlour; participation in a milk recording scheme; and tail clipping of cows at a frequency greater than once per year. Increased level of hygiene of the parlour and cubicles were also associated with lower TBC. Herd management factors associated with bulk tank TBC in Irish grazing herds were generally in agreement with most previous studies from confinement systems of milk production.
AMEP_A_255732 579..585

Department of Medicine, University of Ribeirão Preto, Ribeirão Preto City, Brazil Purpose: Most studies assessing the value of the university admissions test (UAT) to predict academic performance at the end of a medical course were carried out on lecture-based medical courses. However, the association between performance in the UAT with academic achievement at the end of medical course in a problem-based learning (PBL) medical hybrid curriculum remains controversial. The aim of this study was to correlate marks in the UAT with those obtained in the Organized Structured Clinical Examination (OSCE), in the progress testing (PT), and in the final marks of the clerkship (FMC). Methods: We used data from 48 medical students. A single and a multiple dependency studies were performed to assess bivariate and multiple correlation between the UAT or the essay scores (dependent variables) and the OSCE, PT, and FMC (independent variables). Pearson test, multiple linear regression, and ANOVA tests were used and a p-value < 0.05 was considered significant. Results: In the bivariate analysis, only the UAT and FMC marks were correlated (r=0.34; p=0.02). However, the multiple dependency study showed a moderate correlation among UAT, OSCE, PT, and FMC marks (r=0.46; p=0.01). No correlation was found between the essay scores and PT, FMC, and OSCE scores. Conclusion: Our study shows that UAT marks, but not essay scores, can predict academic achievement, particularly in terms of clinical competence (FMC) at the end of a medical course in a PBL hybrid curriculum.
Prognostic value of pretreatment serum albumin−globulin ratio in urothelial carcinoma: A systematic review and meta-analysis

Objective To evaluate whether pretreatment albumin−globulin ratio (AGR) can be used as a biomarker for predicting the prognosis of patients with urothelial carcinoma (UC). Methods We systematically searched PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Google Scholar and Cochrane Library; the search time was up to May 2022. Stata 16.0 was used for data processing and statistical analysis. Results We identified 12 studies with 5,727 patients from 317 unique citations during the meta-analysis. Our results suggested that a low AGR before treatment was significantly associated with poor overall survival (OS) [hazard ratio (HR) = 1.99, 95% confidence interval (CI) = 1.45-2.75, P < 0.001], cancer-specific survival (CSS) [HR=2.01, 95% CI = 1.50-2.69, P < 0.001] and recurrence-free survival (RFS) [HR=1.39, 95% CI = 1.12-1.72, P = 0.002]. Furthermore, we defined different subgroups according to ethnicity, cancer type, cut-off value, sample size and stage. Similar prognostic outcomes for OS and CSS were observed in most subgroups. However, for subgroup of stage, the low pretreatment AGR only predicted the poor survival of patients with non-metastatic UC. Conclusion Our meta-analysis revealed that the AGR before treatment could be used as a predictive biomarker to indicate the prognosis of UC patients during clinical practice, especially in patients with non-metastatic UC.
Multi-center verification of the influence of data ratio of training sets on test results of an AI system for detecting early gastric cancer based on the YOLO-v4 algorithm

Objective Convolutional Neural Network(CNN) is increasingly being applied in the diagnosis of gastric cancer. However, the impact of proportion of internal data in the training set on test results has not been sufficiently studied. Here, we constructed an artificial intelligence (AI) system called EGC-YOLOV4 using the YOLO-v4 algorithm to explore the optimal ratio of training set with the power to diagnose early gastric cancer. Design A total of 22,0918 gastroscopic images from Yixing People’s Hospital were collected. 7 training set models were established to identify 4 test sets. Respective sensitivity, specificity, Youden index, accuracy, and corresponding thresholds were tested, and ROC curves were plotted. Results 1. The EGC-YOLOV4 system completes all tests at an average reading speed of about 15 ms/sheet; 2. The AUC values in training set 1 model were 0.8325, 0.8307, 0.8706, and 0.8279, in training set 2 model were 0.8674, 0.8635, 0.9056, and 0.9249, in training set 3 model were 0.8544, 0.8881, 0.9072, and 0.9237, in training set 4 model were 0.8271, 0.9020, 0.9102, and 0.9316, in training set 5 model were 0.8249, 0.8484, 0.8796, and 0.8931, in training set 6 model were 0.8235, 0.8539, 0.9002, and 0.9051, in training set 7 model were 0.7581, 0.8082, 0.8803, and 0.8763. Conclusion EGC-YOLOV4 can quickly and accurately identify the early gastric cancer lesions in gastroscopic images, and has good generalization.The proportion of positive and negative samples in the training set will affect the overall diagnostic performance of AI.In this study, the optimal ratio of positive samples to negative samples in the training set is 1:1~ 1:2.
