Predicting pediatric length of stay and acuity of care in the first ten minutes with artificial neural networks

Objective To evaluate the efficacy of artificial neural networks in categorizing pediatric trauma patients into four distinct acuity of care groups and in determining the length of stay (LOS) within specific areas of the hospital. Design Using historical information from >8,000 pediatric trauma patient records, train and evaluate artificial neural networks to predict the injury severity and LOS for each patient in pediatric intensive care units (PICUs), step-down units, and floor units. Each artificial neural network is evaluated for categorization accuracy and mean absolute error difference on the predicted LOS. Subjects A total of 10,353 patient records from the National Pediatric Trauma registry, representing all pediatric trauma patients treated at affiliated hospitals from April 1994 through December 1996. Records with incomplete information were eliminated from the study, leaving 8,081 usable patient records. Measurements A total of 14 variables are selected from the 81 values present in the National Pediatric Trauma Registry as independent variables for the artificial neural networks. Each neural network produces nine output values: five for categorizing the patient’s injury severity, three for the LOS in the PICU, step-down unit, and floor units, and one for the patient’s total LOS. Results A fuzzy ARTMAP neural network accurately categorizes 88% of mortality patients and 58.3% of critical PICU patients. A backpropagation neural network succeeded in predicting the total LOS to within 1 day for 51.4% and the ICU LOS to within 1 day for 70.4% of all evaluated patients. Conclusion Information available in the first 10 mins of a patient’s presentation at the emergency room can be used by an artificial neural network to predict injury severity and LOS. Artificial neural networks enable more effective resource planning and patient management.
Broadband ${\rm E}$-Plane Junction for Three-Dimensional Substrate Integrated Waveguide Circuits and Systems

E-plane out-of-phase junction is proposed for three-dimensional (3-D) substrate integrated waveguide (SIW) circuits and systems. Its fabrication is made with low-cost printed circuit board (PCB) process and Lego-style planar building blocks. The proposed structure is validated through the simulation and measurement of an experimental E-plane junction operating from 30 to 40 GHz (28% bandwidth). Over this broadband frequency range, the fabricated prototype shows excellent performances with measured return loss, insertion loss and phase imbalance of better than 16 dB, 0.46 dB, and ±3°, respectively. An integrated wideband dual-polarized array feed is designed and demonstrated on the basis of the proposed E-plane junction. The fabricated array achieves measured isolation of larger than 26 dB and return loss of better than -10.6 dB, with gains of 14 and 14.6 dBi at 35 GHz, respectively, for the vertical and horizontal radiation patterns.
PUBLIC FIRM'S BACKGROUND ON THE PERFORMANCEGOVERNANCE RELATION: EVIDENCE FROM INDONESIA

This study purports to test two governance issues in Indonesian listed firms. To explore corporate governance mechanisms in Indonesia, we ought to understand that listed firms on the Indonesian capital market came from two initial business backgrounds: (1) private firms, which had been private businesses before going public; and (2) Badan Usaha Milik Negara (stateowned enterprises), which were owned by the Indonesian government and managed by government-appointed management. Although both types of the firms have gone public, their differences might remain intact, such as differences in size, lines of business, market share, and the efficiency of corporate governance. Using 442 raw sample from all firms listed on the Indonesian Stock Exchange during 2003-2012, we find that governance characteristics and performance relation does differ between previously SOE firms and previously private firms. However, we do not find evidence of distinct financial performance between previously SOE firms and previously private firms. 1 Corresponding author.

Gene expression of T lymphocytes of gravid cows during preimplantation

An interaction between the conceptus and the immune system of animals is important during implantation. The aim of this study was to clarify the gene expression of T cell subsets in gravid cows during the preimplantation period. Peripheral blood from 14 Holstein dairy cows was taken 14 days after artificial insemination. Based on the gravidity, cows were divided into gravid (n = 8) and nongravid (n = 6) groups. Mononuclear cells from peripheral blood were stimulated with phytohaemagglutinin and then CD4 + , CD8 + , and WC1 + γδ T cell subsets were isolated using magnetic cell sorting. The expression of interferon γ, interleukin 4, and progesterone induced blocking factor were determined using real-time PCR. The expression of interleukin 4 and progesterone induced blocking factor was significantly higher in WC1 + γδ T cells from gravid cows. In addition, interleukin 4 expression in WC1 + γδ T cells from gravid cows was significantly higher than that in CD4 + and CD8+ T cells. This study describes for the first time the important role of WC1 + γδ T cells during the preimplantation period in cows. CD4, CD8, IFN-γ, IL-4, PIBF, WC1
Distributed closed-loop spatial multiplexing for uplink multiuser systems

Focusing on the uplink, where mobile users (each with a single transmit antenna) communicate with a base station with multiple antennas, we treat multiple users as antennas to enable spatial multiplexing across users. Introducing distributed closed-loop spatial multiplexing with threshold-based user selection, we propose two uplink channel-assigning strategies with limited feedback. We prove that the proposed system also outperforms the standard greedy scheme with respect to the degree of fairness, measured by the variance of the time averaged throughput. For uplink multi-antenna systems, we show that the proposed scheduling is a better choice than the greedy scheme in terms of the average BER, feedback complexity, and fairness. The numerical results corroborate our findings.
Foreign Terrorist Fighters: Perspectives from Islamic Organizations in France and Great Britain

This article looks at the phenomenon of Foreign Terrorist Fighters from Europe and sheds light on the position of institutional Islam towards this security threat. The article first looks at how the new trends characterizing the profile and recruitment process of Foreign Terrorist Fighters represent new challenges for counterterrorism, before considering the position of selected Muslim institutions in Europe. The analysis considers two case studies, namely France and Great Britain. Two organizations are used as examples for institutional Islam: the Union of Islamic Organization (UOIF) in France and the Muslim Council of Britain (MCB). The research results reveal a communication centered on the objective of distinguishing Islam from Daesh and a predominant focus on domestic issues such as counterterrorism legislation and general social cohesion.
A Tale of Four Platforms: Motivations and Uses of Facebook, Twitter, Instagram, and Snapchat Among College Students?

The current research explores differences between Facebook, Twitter, Instagram, and Snapchat in terms of intensity of use, time spent daily on the platform, and use motivations. The study applies the uses and gratifications (U&G) approach to contrast the four platforms. A cross-sectional survey of college students (N = 396) asked participants to indicate the intensity of using Facebook, Twitter, Instagram, and Snapchat as well as nine different use motivations. Findings show that participants spent the most time daily on Instagram, followed by Snapchat, Facebook, and Twitter, respectively. They also indicated the highest use intensity for Snapchat and Instagram (nearly equally), followed by Facebook and Twitter, respectively. With regard to use motivations, Snapchat takes the lead in five of the nine motivations. Findings are discussed in relation to the U&G approach and uniqueness of different social media and social networking sites (SNSs).
Dual IHC and FISH Testing for ALK Gene Rearrangement in Lung Adenocarcinomas in a Routine Practice: A French Study

Introduction: In 2011, the French National Cancer Institute recommended ALK-fluorescence in situ hybridization (FISH) testing in all EGFR/KRAS-negative adenocarcinomas by all the hospital molecular genetics platforms of cancers; however, this technique remains time and cost consuming and not suitable for a large-scale screening, in contrast to immunohistochemistry (IHC). Methods: To evaluate IHC as a prescreening tool, 441 specimens, including small biopsies and surgical specimens, were analyzed prospectively on the Grenoble molecular genetics platform. EGFR and KRAS mutation analyses and ALK IHC, using the 5A4 mAb on an automated staining module, were performed on all specimens; 100 were tested by both ALK IHC and FISH (break-apart probe). Results: Twenty-seven cases out of 441 were strongly positive (3+ intensity in more than 60% of cells) with ALK mAb, two additional cases exhibited a faint staining (1+) in less than 30% of the cells. Among the 100 cases analyzed by IHC and FISH, 19 were not interpretable by FISH, but 21 were positive with both techniques. Sensitivity and specificity of IHC when compared with FISH were 95 and 100%, respectively. Eleven patients were included in crizotinib trials. Among the 352 analyzable specimens for mutations, 7% were EGFR and 29% were KRAS mutated. Conclusions: Our IHC protocol, using a commercially available antibody and an amplification step on an automated staining module, led to intense cytoplasmic staining in 6.5% of the adenocarcinomas screened. Our results favor ALK IHC prescreening on a daily routine on surgical specimens and on small biopsies before FISH testing.
What contributes to convention attendee satisfaction and loyalty? A meta-analysis

ABSTRACT The significant economic contribution and other positive impacts of the convention industry make it imperative to understand the factors that influence attendees' satisfaction and generate repeat attendance, which is loyalty. A meta-analysis of the convention literature revealed that networking and education are the top contributors to attendee satisfaction. Interestingly, the findings suggest that convention environment is more important for loyalty than satisfaction, whereas destination image is relatively unimportant for either outcome. Perception of service quality is more important than value for both satisfaction and loyalty. The meta-analysis confirmed that there is a strong relationship between attendee satisfaction and loyalty.
Trading with China: Productivity Gains, Job Losses

We analyze the impact on productivity in advanced economies of fast-growing trade with China between the mid-1990s and late-2000s, separately identifying the export and import channels. We use country-sector-level data for 18 advanced economies and, similar to Autor, Dorn, and Hanson (2013), exploit exogenous variation in trade with China in a given country-sector by instrumenting imports from (exports to) China in a given country-sector with the average imports from (exports to) China in the same sector in other advanced economies. Our estimates point to large productivity gains from trading with China—the (exogenous) rise of China in global trade may have increased the level of total factor productivity by about 1.9 percent, or 12.3 percent of the overall increase over the sample period, in the median country-sector. By contrast, using a similar empirical strategy, we find adverse employment effects of Chinese imports in exposed country-industries, consistent with previous studies. Taken together, these findings point to large gains from free trade, while underscoring the scope for a more active policy role in redistributing them, particularly by easing workers’ transition between jobs and industries.
Sexual selection in a hermaphroditic plant through female reproductive success

Sexual selection is well accepted as a mechanism of shaping traits in animals. However, whether and how floral traits are sexually selected in hermaphroditic plants remains less clear. Here, we use Passiflora incarnata to address how floral traits that affect pollination success are selected via female function. We manipulated the ecological context by limiting pollination and adding resources to expand the phenotypic distribution and alter the intensity of sexual selection. Total sexual selection favoured lower style deflexion because of its impact on pollen receipt and subsequent seed number. However, total selection on style deflexion was not significant, indicating additional selection on style deflexion through routes other than mating. Limited pollination and enhanced resources were expected to alter the distribution of pollen deposition and seed production and therefore intensify the Bateman gradient – the relationship between pollen receipt and seed production. Indeed, the Bateman gradient was strongest when pollination was limited, suggesting potential for sexual selection to influence floral trait evolution under these conditions. Overall, we found floral traits may be shaped by sexual selection through female reproductive success in this hermaphroditic plant. These results support manipulations to enhance the variance in mating as a mechanism to understand patterns of sexual selection.
An overview of Hierarchical Temporal Memory: A new neocortex algorithm

The overview presents the development and application of Hierarchical Temporal Memory (HTM). HTM is a new machine learning method which was proposed by Jeff Hawkins in 2005. It is a biologically inspired cognitive method based on the principle of how human brain works. The method invites hierarchical structure and proposes a memory-prediction framework, thus making it able to predict what will happen in the near future. This overview mainly introduces the developing process of HTM, as well as its principle, characteristics, advantages and applications in vision, image processing and robots movement, some potential applications by using HTM, such as thinking process, are also put forward.
Design of a compact, battery-powered rep-rate charger for an 88-kJ capacitor bank for EML applications

The Materials Testing Facility (MTF) at the U.S. Naval Research Laboratory (NRL) is developing a battery-powered, rep-rate charger for an 88-kJ capacitor bank. The goal is to charge a 7000-μF capacitor to 5-kV in four seconds for a fifty shot burst. A bank of LiFePO4 batteries is used with a full H-bridge converter, a transformer, and a rectifier to transform the 500V battery voltage to a 5-kV secondary voltage. A key parameter is to minimize the converter weight and volume; therefore the switching frequency needs to be as high as possible to reduce the size of filter components and transformers. However, as the frequency increases, switching losses will begin to dominate and a practical limit will be reached before the device switching maximum is reached. In addition to the design of stable battery packs, most of the work has been focused on switch design and driver optimization, utilizing techniques such as resonate switching and active feedback control systems. This paper will present simulation data and results from experiments.
Association of the −160 C → a promoter polymorphism of E‐cadherin gene with gastric carcinoma risk

A −160 C → A polymorphism in the promoter region of E‐cadherin has been shown to decrease gene transcription. This allelic variation might be a potential genetic marker for identifying individuals at risk for cancer. There remains no report regarding the polymorphism of E‐cadherin in gastric carcinoma (GC).
Does the Risk Outweigh the Benefits? Adolescent Responses to Completing Health Surveys

The aim of this study is to describe the self-reported experiences of adolescents in population-based samples when completing health-related surveys on topics with varying potential for evoking distress. Survey data were collected in three school-based studies of bullying behaviors (N = 1,771, 12-14 years), alcohol use (N = 823, 12, 15, and 17 years), and electronic image sharing (N = 274, 13 years). Between 5% and 15% of respondents reported being upset at survey completion, but at most 1.4% were entirely negative in their evaluation. Age was not associated with being upset, but younger adolescents were more likely to see benefit in participation. Although concurrent mental health symptoms increased the risk of being upset, this was mostly mitigated by perceived benefits from participation.
FTIR Spectrum of Phenocryst Olivine as an Indicator of Silica Saturation in Magmas

Fourier Transform infrared (FTIR) absorption spectra of hydroxyl were measured on olivine phenocrysts from hydrous basaltic melts that originated in island-arc tectonic settings. The basaltic melts encompass a wide range of silica activities from orthopyroxene-saturated hypersthene-normative to nepheline-normative compositions. The intensities and wavenumber placement of hydroxyl absorption bands correlate with the degree of silica saturation of the parent melt from which the olivine crystallized. Olivines from silica-undersaturated nepheline-normative melts absorb IR radiation in the wavenumber range 3430-3590 cm(-1) (Group 1). In contrast, olivines from orthopyroxene-saturated boninitic melts exhibit hydroxyl absorption bands in the wavenumber range 3285-3380 cm(-1) (Group 2). Olivines crystallized at intermediate silica activities exhibit a combination of the two groups of hydroxyl IR bands, where the proportion of Group 2 bands increases with increasing silica saturation of the parent melt. The positions of hydroxyl absorption peaks observed here for natural samples are consistent with previous measurements on experimentally annealed olivines. Thus protonation experiments can be employed to make spectroscopically dry olivine structures visible by IR, yielding information on the silica saturation of the parental magmas. Hydroxyl concentrations in the studied olivines were estimated to be 1-2 ppm, corresponding to an olivine-melt partition coefficient of similar to(1.0 +/- 0.3) x 10(-4).
A coupled feature representation based MRI biomarker for Alzheimer's disease prediction

Mild Cognitive Impairment (MCI) is an inevitable stage before patient convert to Alzheimer's disease (AD). In MCI cases, only part will further progress to AD. This progress is irreversible and highly lethal. Based on that fact, precisely predict who will convert to AD could allow the MCI patients to receive timely treatment for delaying the onset of symptoms, and this also highly helpful to the clinical trials research. In this work, we proposed a novel biomarker based on Coupled Feature Representation of Magnetic Resonance (MR) images for the AD conversion prediction. First, we adopted a Taylorlike expansion based Coupled Feature Representation method to obtain the linear and nonlinear information between the regional features. Then a support vector machine (SVM) classifier was trained to evaluate decision values of each sample, which we call the coupling biomarker. Ultimately, the coupling biomarker is connected with age and cognitive measures(CM) to obtain the final prediction. In the experimental results, the proposed coupling biomarker achieved a 10-fold cross-validated (CV) Accuracy (ACC) of 75.4%, and area under the receiver operating characteristic curve (AUC) of 81.7% in prediction task for MCI subjects, and the combined biomarker further achieved a 10-fold CV ACC of 84.4% and AUC of 92.0%. In the last, the joint biomarker which merge the coupling and grading biomarkers achieved a 10-fold cross-validated ACC of 85.7% and AUC of 92.6%, and both SPE and SEN higher than 80.0%. The results presented in this study demonstrate a significant contribution in accurate prediction and also the potential and expandable of the framework for prediction of conversion from MCI to AD.
The Role of Goal Frames regarding the Impact of Gamified Persuasive Systems on Sustainable Mobility Behavior

This study analyzes the motivational processes of a gamified persuasive system in an initiative to encourage sustainable mobility behavior by promoting bike usage. To increase motivation and drive sustainable behavior, the design of persuasive systems is gradually advancing. Game-based functions are often implemented to transform the user experience through playful interactions. This paper explores whether the functions implemented within gamified persuasive systems really fulfill an individual’s goals and needs by analyzing the impact of the user’s personal goals on gamified persuasive system usage and the desired outcome in the domain of sustainable mobility behavior. The theoretical basis for this study comes from the goal-framing theory as well as the perspective of functional affordances. The results in this work indicate that the functions implemented are only partially compatible with user goals. Furthermore, the results demonstrate that the influence of goals on sustainable mobility behavior can be increased through the implementation of specific functions within a persuasive system.
Spectral Optical Coherence Tomography in Video-Rate and 3D Imaging of Contact Lens Wear

Purpose. To present the applicability of spectral optical coherence tomography (SOCT) for video-rate and three-dimensional imaging of a contact lens on the eye surface. Methods. The SOCT prototype instrument constructed at Nicolaus Copernicus University (Torun, Poland) is based on Fourier domain detection, which enables high sensitivity (96 dB) and increases the speed of imaging 60 times compared with conventional optical coherence tomography techniques. Consequently, video-rate imaging and three-dimensional reconstructions can be achieved, preserving the high quality of the image. The instrument operates under clinical conditions in the Ophthalmology Department (Collegium Medicum Nicolaus Copernicus University, Bydgoszcz, Poland). A total of three eyes fitted with different contact lenses were examined with the aid of the instrument. Before SOCT measurements, slit lamp examinations were performed. Results. Data, which are representative for each imaging mode, are presented. The instrument provided high-resolution (4 &mgr;m axial × 10 &mgr;m transverse) tomograms with an acquisition time of 40 &mgr;s per A-scan. Video-rate imaging allowed the simultaneous quantitative evaluation of the movement of the contact lens and assessment of the fitting relationship between the lens and the ocular surface. Three-dimensional scanning protocols further improved lens visualization and fit evaluation. Conclusions. SOCT allows video-rate and three-dimensional cross-sectional imaging of the eye fitted with a contact lens. The analysis of both imaging modes suggests the future applicability of this technology to the contact lens field.
