A Novel Nomogram for Predicting Morbidity Risk in Patients with Secondary Malignant Neoplasm of Bone and Bone Marrow: An Analysis Based on the Large MIMIC-III Clinical Database

Objective Bone and bone marrow are the third most frequent sites of metastases from many cancers and are associated with low survival and high morbidity rates. Currently, there are no effective bedside tools to predict the morbidity risk of these patients in general intensive care units (ICUs). The main objective of this study was to establish and validate a nomogram to predict the morbidity risk of patients with bone and bone marrow metastases. Methods Data on patients with bone and bone marrow metastases were extracted from the Medical Information Mart for Intensive Care III (MIMIC-III) database. The patients were divided into training and validation cohorts. The data were analyzed using univariate and multivariate Cox regression methods. Factors significantly and independently prognostic of survival were used to construct a nomogram predicting 30-day morbidity. The nomogram was validated by various methods, including Harrell’s concordance index (C-index), area under the receiver operating characteristic curve (AUC), calibration curve, integrated discrimination improvement (IDI), net reclassification index (NRI), and decision curve analysis (DCA). Results The study included 610 patients in the training cohort and 262 in the validation cohort. Multivariate Cox regression analysis showed that temperature, SpO2, Sequential Organ Failure Assessment (SOFA) score, Oxford Acute Severity of Illness Score (OASIS), comorbidities with coagulopathy, white blood cell count, heart rate, and respiratory rate were independent predictors of patient survival. The resulting nomogram had good discriminative ability, as shown by high AUCs, and was well calibrated, as demonstrated by calibration curves. Improvements in NRI and IDI values suggested that the nomogram was superior to the SOFA scoring system. DCA curves revealed that the nomogram showed good value in clinical applications. Conclusion This prognostic nomogram, based on demographic and laboratory parameters, was predictive of the 30-day morbidity rate in patients with secondary malignant neoplasms of the bone and bone marrow, suggesting its applicability in clinical practice.
Reference values for bone density and bone mineral content from 5 to 80 years old in a province of Chile

Background The assessment of bone health throughout the life cycle is essential to determine fracture risk. The objectives of the work were (a) compare bone mineral density and content with international references from the United States, (b) determine maximum bone mass, (c) propose references for bone health measurements from ages 5 to 80 years old. Methods Research was carried out on 5,416 subjects. Weight and height were measured. Body Mass Index (BMI) was calculated. The total body was scanned using dual energy X-ray absorptiometry (DXA). Information was extracted from the bone health measures (bone mineral density (BMD) and bone mineral content (BMC)) for both sexes, according to pediatric and adult software. Results and Discussion Differences were identified between the mean values of Chilean and American men for BMD (~0.03 to 0.11 g/cm2) and BMC (~0.15 to 0.46 g). Chilean females showed average values for BMD similar to the US references (~−0.01 to 0.02 g/cm2). At the same time, they were relatively higher for BMC (~0.07 to 0.33 g). The cubic polynomial regression model reflected a relationship between BMD and BMC with chronological age in both sexes. For males, R2 was higher (R2 = 0.72 and 0.75) than for females (R2 = 0.59 and 0.66). The estimate of maximum bone mass (MBM) for males emerged at 30 years old (1.45 ± 0.18 g/cm2 of BMD and 3.57 ± 0.60 g of BMC) and for females at age 28 (1.22 ± 0.13 g/cm2 of BMD and 2.57 ± 0.44 g of BMC). The LMS technique was used to generate smoothed percentiles for BMD and BMC by age and sex. Results showed that maximum bone mass occurred in females at age 28 and in males at 30. Reference values obtained from this research may be used to evaluate bone health, diagnose bone fragility and osteoporosis in individuals and regional population groups.
THE IMPACT OF CULTURAL ASSUMPTIONS ABOUT LANGUAGE ON COLLABORATION IN GLOBAL VIRTUAL PROJECT NETWORKS

The globalization of the architecture, engineering and construction industry has led to more work executed in Global Virtual Project Networks (GVPNs). The challenges to network performance due to the cultural and linguistic diversity that characterizes these networks has been welldocumented. However, the interface between language and culture and its role in network interactions is not well understood. Our research seeks to explore this interface by examining how cultural assumptions about language can impact collaboration in GVPNs. Based on a mixed-method, grounded-theory approach, we investigate how the informal linguistic style of individuals within the network lead to negative evaluations, which in turn serve to marginalize those individuals who adopt this style. Our results demonstrate that linguistic diversity can negatively impact network cohesion because of the different cultural assumptions that individuals ascribe to linguistic styles.
Automated fruit grading system using image processing

This paper describes the operations and performance of an automated quality verification system for agricultural products and its main features. The system utilizes improved engineering designs and image-processing techniques to convey and grade products. Basically two inspection stages of the system can be identified: external fruit inspection and internal fruit inspection. Surface inspection is accomplished through processing of color CCD images while internal inspection employs special sensors for sugar and acid content. An X-ray sensor is incorporated to detect biological defects.
Numerical Investigation of Blade Lean and Sweep affecting Secondary Flows in an Axial Expansion Turbine

Based on an axial expansion turbine used for energy recovery from working fluids an automated CFD-flow optimization was performed to increase the turbine efficiency without narrowing the operating range. The optimization results showed that even small changes in the optimization target had a significant influence on the lean and sweep of the new blade designs. The resulting blade shapes were extraordinary. The lean and sweep resembled more that of thermal turbomachinery than hydraulic machinery. It became clear that the special blade shapes were a result of the very low aspect ratio of the turbine and the resulting large influence of secondary flows. The blade lean and sweep induce secondary flow structures which are of decisive importance for the turbine performance. The simulation results showed that positive compound lean increases the efficiency and positive compound sweep improves the cavitation behavior of the investigated axial expansion turbine. However the complexity of the occurring secondary flows make an universally valid statement on the effect of blade lean and sweep on the flow behavior of an axial turbine impossible.
Banking service quality management using fuzzy FMEA (a case study: Central Melli Bank of Rafsanjan)

The purpose of all service institutions, including banks, is to provide appropriate services for the customers' satisfaction. Therefore, due to the importance of quality in service industries and its significant effects on customer satisfaction, the question arises: how the quality of service can be evaluated? This case study also sought to assess the quality of banking services using failure mode and effect analysis (FMEA) techniques in fuzzy environment in one of the branches of Melli Bank of Rafsanjan. In FMEA technique, the risk priority number (RPN) index was used for rating the failure items, which is the multiplication of three risk factors: occurrence of failure, severity of failure and detectability of failure. In FMEA technique, the weights of risk factors weight are not taken into account, such that, the same weight value is assumed for each of those factors. To overcome this weakness, much research has been performed, recently. This paper uses Wang and colleagues' model in a fuzzy environment. The results illustrate that one of the most significant failure items is lack of a proper location to park the customers' car.

Molecular dynamics study on the thermal conductivity of multiple layers in semiconductor disk laser

Thermal properties of multiple layers including distributed Bragg reflector (DBR) and multiple quantum wells (MQWs) used in the semiconductor gain element are crucial for the performance of a semiconductor disk laser (SDL). For the purpose of more reasonable semiconductor wafer design, so to improve the thermal management of SDLs, accurate thermal conductivity value of a DBR is under considerable requirement. By the use of equilibrium molecular dynamics (EMD) method, thermal conductivities of AlAs/GaAs DBRs, which were widely employed in 1μm wavelength SDLs, were calculated, and simulated results were compared with reported data. Influences of the Al composition, and the layer thickness on the thermal conductivities were focused and analyzed.
Development of a new program to estimate the conductor temperature of underground transmission cables in the buried ducts

Tokyo Electric Power Co. and the Japan Research Institute, Ltd. have jointly developed a new conductor temperature estimation program that makes use of the finite element method, as a tool for calculating at high precision the transmission capacity of a cable installed in a buried duct. This program newly incorporates seasonal changes in air and ground temperature, ground-surface boundary conditions for sunlight and radiation, and temperature changes in the depth direction. Heretofore it has been impossible to vary the load current, but this time it was possible to obtain more realistic simulation results than by the previous stationary-current analysis, by allowing transient-current analysis to which daily and seasonal fluctuations are added. And by employing the finite element method, it has become possible to calculate the temperature even for locations other than the cable conductor temperature (example: the cable surface temperature).
Sagnac Interferometer with Reflectors for Detecting and Localizing Phase Sensitive Events in Fiber Optic Cables

A Sagnac interferometric system to detect, identify and locate phase sensitive events in fiber optic cables, with early warning capabilities is presented. The system makes use of two standard fibers that are already installed. Two Super Luminescent Diodes (SLD) are used as the sources. The sensing fiber is terminated by a fiber mirror reflector. The monitoring is done from a centralized location where the detection opto- electronics is located. Spatial event localization within 200m is demonstrated for a monitoring length of 40Km I.INTRODUCTION Distributed optical fiber sensors are commonly used for monitoring of pipelines, optical communication links and for the protection of restricted areas. Earlier, the detection methods were based on intensity modulated sensors, which does monitoring based on the variation of optical intensity as a result of the bending of fibers, tapping of fiber optic links etc. Thus detection was possible only after the event had actually occurred. However, the sensing scheme which is able to detect phase sensitive events can provide advance warning, using the fiber cable as a distributed sensor. The two possible methods for the detection of phase sensitive events are Phase Optical Time Domain Reflectometry (Ф-OTDR) and Interferometry.
The use of ambient audio to increase safety and immersion in location-based games

The purpose of this thesis is to propose an alternative type of interface for mobile software being used while walking or running. Our work addresses the problem of visual user interfaces for mobile software being potentially unsafe for pedestrians, and not being very immersive when used for location-based games. In addition, location-based games and applications can be difficult to develop when directly interfacing with the sensors used to track the user’s location. These problems need to be addressed because portable computing devices are becoming a popular tool for navigation, playing games, and accessing the internet while walking. This poses a safety problem for mobile users, who may be paying too much attention to their device to notice and react to hazards in their environment. The difficulty of developing location-based games and other location-aware applications may significantly hinder the prevalence of applications that explore new interaction techniques for ubiquitous computing. We created the TREC toolkit to address the issues with tracking sensors while developing location-based games and applications. We have developed functional location-based applications with TREC to demonstrate the amount of work that can be saved by using this toolkit. i In order to have a safer and more immersive alternative to visual interfaces, we have developed ambient audio interfaces for use with mobile applications. Ambient audio uses continuous streams of sound over headphones to present information to mobile users without distracting them from walking safely. In order to test the effectiveness of ambient audio, we ran a study to compare ambient audio with handheld visual interfaces in a location-based game. We compared players’ ability to safely navigate the environment, their sense of immersion in the game, and their performance at the in-game tasks. We found that ambient audio was able to significantly increase players’ safety and sense of immersion compared to a visual interface, while players performed significantly better at the game tasks when using the visual interface. This makes ambient audio a legitimate alternative to visual interfaces for mobile users when safety and immersion are a priority.
Improved MESFET characterization for analog circuit design and analysis

The third derivative of MESFET drain current behavior is useful for devise characterization. It provides information necessary to device a model to predict large-signal dynamic behavior with accuracy over an extended range of operating conditions. Extra parameters are proposed to define behavior in subthreshold and triode operating regions. A continuously differentiable form that models third-order behavior correctly describes these regions. The result is an accurate large-signal model suitable for design and analysis of distortion and intermodulation in analog circuits. <<ETX>>
A portable W-band radar system for enhancement of infrared vision in fire fighting operations

In this paper, we present a millimeter wave radar system which will enhance the performance of infrared cameras used for fire-fighting applications. The radar module is compact and lightweight such that the system can be combined with inertial sensors and integrated in a hand-held infrared camera. This allows for precise distance measurements in harsh environmental conditions, such as tunnel or industrial fires, where optical sensors are unreliable or fail. We discuss the design of the RF front-end, the antenna and a quasi-optical lens for beam shaping as well as signal processing and demonstrate the performance of the system by in situ measurements in a smoke filled environment.
ROSA, A FLEXIBLE LOADING PATTERN OPTIMIZATION TOOL FOR PWRs

Core design is a challenging optimization problem due to the vast number of loading pattern possibilities, in combination with a variety of complex constraints and economical targets. The ROSA code system has been developed at NRG for PWR core design and utilizes Simulated Annealing as optimization technique in combination with a very fast and accurate 3-D core simulator code. With this code millions of loading patterns (including cycle depletion) can be evaluated on a workstation in a day. Several new developments with regard to rules and optimization parameters have been realized recently e.g. a true shutdown margin parameter has been implemented. With the ROSA code system economic core designs with challenging constraints have been realized. It is concluded that the ROSA code is a powerful tool for core design and has been applied successfully in a variety of cases.
A TOOL FOR EMOTIONAL USER EXPERIENCE ASSESSMENT OF WEB-BASED MEDICAL SERVICES

Emotional User Experience Design (eUXD) has become increasingly important for web-based services. The primary objective of this study is to enable users to use websites that are easy to understand and operate and pleasing to use. A checklist tool for an emotional user experience (eUX) assessment that supports web-based medical services is proposed. This tool measures user moods while using medical services’ websites. The tool allocates emotive design-oriented problems and thus defines relevant website design recommendations. A case study was performed illustrating the proposed tool on a website offering medical services. Five variants of this website with different design element categories were created. These variants were assessed, analyzed, and proposed for further redesign in applying the tool. The results reveal the variant and website design elements that best influenced eUX. Significant improvement in eUX is expected with implementation of design recommendations of this study. The advantages of the tool are: (1) measuring emotional responses of medical website users, (2) allocating emotive problems, (3) defining of recommendations for eUX design of web-based medical services, and (4) creation of suitable practices for eUX design of web-based medical services.
ANALYSIS OF HEAT EXTRACTION FROM THE HIJIORI AND OGACHI HDR GEOTHERMAL RESOURCES IN JAPAN

Heat extraction from HDR geothermal resources in Japan has been carried out in several circulation tests under experimental development programs supported by the Japanese government and the electric utilities of Japan. Two major HDR resources under current investigation are the Hijiori HDR reservoir (by NEDO) and the Ogachi HDR reservoir (by CRIEPI) both in the northern Honshu region of Japan. Several circulation tests of one to several months have been conducted in each resource to obtain reservoir flow characteristics necessary for planning long-term production tests in later phases of the two programs. For optimum thermal analysis of the resources, expectations of energy extraction behavior is needed to evaluate the resources for commercial energy mining operations. Several aspects of the two resources, such as geologic structure and total resource size and heat content as defined by the temperature distribution in relation to the reservoir stimulation geometry needs further analysis. To assist in evaluating the thermal extraction aspects of the tests, comparison of modeling forecasts with measured test data were carried out. Heat extraction calculations with the Stanford Geothermal Program heat-sweep model, based on radial sector flow estimation, were made for the several circulation tests during the 1990s. The resulting calculations of thermal energy extraction from the test segments were accumulated to evaluate long-term expectations for each resource. Analysis of the combined data for the two somewhat differently stimulated HDR resources should be of value in evaluation of the northern Honshu region of Japan a s a long-term useful source of HDR geothermal-energy-derived electric power.
Advanced seismic signal processing techniques for detection and bearing estimation of footsteps and vehicular signals

This thesis is aimed towards the development of algorithms for improved detection and bearing estimation of human activities in urban surveillance systems. Human footsteps and vehicles are used as sources and seismic signals, generated from these sources, are recorded using a (buried) tri-axial geophone. The performance of existing energy-based metrics deteriorate significantly with increasing source-sensor distance due to poor signalto-noise ratio. The three-dimensional (3D) trajectory traced by the tri-axial signal, acquired from near-field seismic sources, is elliptically polarized. This thesis takes as its point of departure the direction attribute of the elliptically polarized 3D trajectory to detect and estimate the direction of arrival of surface seismic sources. The smoothness of the 3D trajectory is used as a feature and instantaneous metrics using consecutive snapshots of the normalized trajectory are defined. Furthermore, the 3D trajectory is analyzed using two different representations of the hypercomplex quaternions. Using the vector-quaternion representation a quaternion generalized Gaussian distribution (QGGD) is derived. The QGGD is parameterized by a shape parameter and a quaternion augmented covariance matrix to capture non-Gaussianity and inter-channel correlation, respectively, of the tri-axial signals. The orientation-quaternion representation is used to parameterize the instantaneous orbital phase of the trajectory. The concentration and direction of the orbital phase are used to detect the presence of elliptical polarization and to estimate the bearing of seismic surface sources, respectively. The proposed trajectory-based metrics were found to improve the detection range of human footstep signals by 5 m to 7 m and vehicular signals by 25 m to 100 m, compared with existing energy-based detection metrics. The orientation-quaternion representation of the 3D trajectory enhanced bearing estimation accuracy, in addition to addressing the ±90◦ ambiguity that occurred in existing methods. vi
Sampling effects in quantum mechanical/molecular mechanics trajectory surface hopping non-adiabatic dynamics

The impact of different initial conditions in non-adiabatic trajectory surface hopping dynamics within a hybrid quantum mechanical/molecular mechanics scheme is investigated. The influence of a quantum sampling, based on a Wigner distribution, a fully thermal sampling, based on classical molecular dynamics, and a quantum sampled system, but thermally equilibrated with the environment, is investigated on the relaxation dynamics of solvated fulvene after light irradiation. We find that the decay from the first singlet excited state to the ground state shows high dependency on the initial condition and simulation parameters. The three sampling methods lead to different distributions of initial geometries and momenta, which then affect the fate of the excited state dynamics. We evaluated both the effect of sampling geometries and momenta, analysing how the ultrafast decay of fulvene changes accordingly. The results are expected to be of interest to decide how to initialize non-adiabatic dynamics in the presence of the environment.
