A multi-hop relay based frequency synchronization for D2D communication in 3GPP LTE system

Device-to-device (D2D) communication has been adopted for one of the next generation technologies to support commercial/ social service and public safety application in 3-rd generation partnership project (3GPP). For D2D operation in partial network coverage (PNC) scenario, synchronization among multiple user equipments (UE) is the most important issue due to asynchronous interference which can occur among in-network coverage (INC) UEs and out-of-network coverage (ONC) UEs. Therefore, 3GPP agreed multi-hop relay based synchronization. In this method, UE considers a source type, the number of hops, and received power of D2D synchronization signal (D2DSS) to select one D2DSS among multiple D2DSSs. However, this method cannot consider actual frequency offsets of D2DSS, which are accumulated through the previous multi-hop links. For that reason, it is not suitable for multi-hop relay based frequency synchronization. Therefore, in this paper, we propose a novel frequency synchronization method where UE considers an absolute sum of frequency offsets which actually occurs in the multi-hop links of D2DSS. Also, by using frequency offset based threshold, the proposed method provides a strict condition to perform D2DSS relay. We verify that the proposed method can efficiently reduce frequency offsets among UEs in PNC scenario.
Two pointer input for 3D interaction

Weexplore a range of techniques that use two hands to control two independent cursors to perform operations in 3D desktop applications. Based on research results in 2D applications, we believe that two-handed input provides the potential for creating more efficient and more fluid interfaces, especially for tasks that are context-sensitive or that have many degrees of freedom. These tasks appear frequently in 3D applications and are commonly broken down into a series of sequential operations, each controlling fewer degrees of freedom – even though this may dramatically change the character of the task. However, two-handed interaction, in theory, makes it possible to perform the same tasks using half the number of sequential steps since two previously sequential operations can be performed simultaneously. In addition, many forms of two-handed interaction may be simpler to use and to understand since they correspond to common interactions in the physicat world. It is significant when tasks that need to be broken down into two sequential single-cursor steps, can be performed as a single fluid operation using two cursors.
Eine Untersuchung der Potentiale automatisierter Abstraktionsansätze für Geschäftsprozessmodelle im Hinblick auf die induktive Entwicklung von Referenzprozessmodellen

In der Literatur wurde bereits eine Reihe von Ansatzen zur Abstraktion fur Geschaftsprozessmodelle identifiziert und daruber hinaus verschiedene allgemeine Anwendungsszenarien vorgestellt. Die induktive Entwicklung von Referenzmodellen stellt eine weitere mogliche Anwendung bereits bestehender Abstraktionsansatze dar. Dieser Beitrag zielt darauf ab, Abstraktion in Geschaftsprozessmodellen im Allgemeinen sowie konkret einige dieser Ansatze bezuglich ihrer Eignung zur Entwicklung von induktiven Referenzprozessmodellen zu bewerten. Dazu wird ein generischer Algorithmus entwickelt, der aus einer Menge von Prozessmodellen ein Referenzprozessmodell gewinnt, indem die Modelle gemas der Vorgehensweise des verwendeten Ansatzes abstrahiert und die abstrahierten Modelle anschliesend zusammengefugt werden. Dieses Vorgehen wird genutzt, um acht verschiedene Abstraktionsansatze hinsichtlich ihrer Potentiale im Rahmen der induktiven Entwicklung von Referenzmodellen zu evaluieren, indem sie auf eine Menge von Modellen angewendet werden. Die resultierenden Referenzmodelle werden bewertet und verglichen, um einen Uberblick uber die verschiedenen Ansatze und ihre Eignung zu erhalten.
Dielectric Resonator Antenna as a RFID Tag for Human Identification System in Wrist Watch

Abstract Radio Frequency Identification (RFID) has been considered as a time and money-saving solution for a wide variety of applications, such as manufacturing, supply chain management, and inventory control. However, there is a growing need in the RFID community to research and find out the tag with miniature, circular polarized radiation patterns, dual band operation, high radiation efficiency and high bandwidth operations. This paper presents compact radio frequency identification (RFID) tag for human identification system in wrist watch. Dielectric resonator antenna (DRA) with patch is used as an active tag. The proposed antenna is operated on dual frequency bands. Simple microstrip line is used as a feeding mechanism. It is operated at 2.4 GHz and 5.8 GHz frequency band. It has circular polarization radiation patterns. Simulation results are presented on various parametric studies on the RFID tag.
A comparative study of backlash compensation methods

This paper describes three different approaches to compensation of backlash influence in a position-controlled system. The influence of backlash in a cascade structured position controller (method 1) with inner torque control loop is compensated by utilizing a fast linear torque controller, at the expense of having to measure the torque on shaft. Defining the model of backlash (method 2) allows for compensation of backlash influence by superposition of compensation signal. However, this method is more sensitive to measurement noise. Variable structure controller (method 3) (one for linear, and the other for nonlinear regime) proved well, with constraints on input signal. These methods were chosen because they were judged most appropriate with respect to constructional and computational constraints in the controlled system. Excellent system behaviors had been experimentally verified on a laboratory model, when proposed control concepts were utilized.
Efficient targeting of gene expression in chick embryos by microelectroporation

During vertebrate embryonic development, a key to unraveling specific functions of gene products is the capability to manipulate expression of the gene of interest at the desired time and place. For this, we developed a ‘microelectroporation’ technique by which DNA can be locally introduced into a targeted site of avian embryos, restricting spatial expression of the protein products during development. This technique involved injection of DNA solution in ovo around the target tissue and pinpoint application of an electric field by tungsten electrodes, allowing efficient and reproducible targeted gene transfer, for example, into an optic vesicle, somites, cranial mesoderm and limb mesenchyme. Because of the locality of gene introduction and its expression, survival rates of the embryos were high: approximately 90% of the embryos injected in optic vesicles were alive for at least 1 day after microelectroporation. The instantaneous gene transfer into embryonic cells allowed rapid expression of protein products such as green fluorescence protein within 2.5 h with fluorescence maintained for 3 days of incubation. This improved technique provides a convenient and efficient way to express transgenes in a spatially and temporally restricted manner in chicken embryos.
Improving Machine Learning Ability with Fine-Tuning

Item Response Theory (IRT) allows for measuring ability of Machine Learning models as compared to a human population. However, it is difficult to create a large dataset to train the ability of deep neural network models (DNNs). We propose fine-tuning as a new training process, where a model pre-trained on a large dataset is fine-tuned with a small supplemental training set. Our results show that fine-tuning can improve the ability of a state-of-the-art DNN model for Recognizing Textual Entailment tasks.
ASHP national survey of pharmacy practice in hospital settings: dispensing and administration--2008.

PURPOSE Results of the 2008 ASHP national survey of pharmacy practice in hospital settings that pertain to dispensing and administration are presented. METHODS A stratified random sample of pharmacy directors at 1310 general and children's medical-surgical hospitals in the United States were surveyed by mail. RESULTS The response rate was 40.2%. Most hospitals had a centralized medication distribution system; however, there is evidence of growth in decentralized models compared with data from 2005. Automated dispensing cabinets were used by 83% of hospitals and robots by 10%. The percentage of doses dispensed in unit dose form increased, as did the use of two-pharmacist checks for high-risk drugs and high-risk patient groups. Medication administration records (MARs) have become increasingly computerized over the past nine years, and the use of handwritten MARs has declined substantially. Technology implemented at the drug administration step of the medication-use process is continuing to increase. Bar-code technology was implemented in 25% of hospitals, and 59% of hospitals had smart infusion pumps. Only 6.8% of hospitals had a pharmacist practicing in the emergency department (ED). Pharmacists prospectively reviewed only a small percentage of ED medication orders before the first dose was administered, and only 40.7% of hospitals retrospectively reviewed ED medication orders for prescribing errors. Pharmacy hours of operation have been increasing, with 36.2% of hospitals providing around-the-clock services. Off-site medication order review was used in 20.7% of hospitals. Directors of pharmacy reported a vacancy rate of 5.9% for pharmacists and 4.7% for technicians and a turnover rate of 8.6% for pharmacists and 13.8% for technicians. CONCLUSION Safe systems continue to be in place in most hospitals, but the adoption of new technology is rapidly changing the philosophy of medication distribution. Pharmacists are continuing to improve medication use at the dispensing and administration steps of the medication-use process.
Robust localization system for an autonomous mower

This paper presents a robust vision-based localization system for an autonomous mower, which is significant for both the meadow map building and the successful area covering. Instead of setting the monocular camera toward the scene, which suffers from the disturbance of moving objects, less mark points or variation of illumination, we equip the camera toward the ground with constant illumination compensation. To achieve the localization of the mower, point features are extracted and matched between pairs of frames. Motion is incremental obtained by calculate the rotation and translation transformation of matched feature point pairs. As the angle accumulated error has greater contribution to the location error, angular acceleration sensor is adopted to compensate the angle error especially in the steep turning case. Experiments on meadow with our mowers demonstrate the robustness of our localization system.
Simulated moving-bed adsorption for separation of racemic mixtures

The two enantiomers that constitute a racemate have different activities when employed as pharmaceuticals. Due to this fact, fully recognized today, the pharmaceutical industry has been forced to market pure enantiomers instead of the racemic mixture whenever a chiral compound is involved. The simulated moving bed (SMB) is a chromatographic process that, unlike traditional HPLC systems, operates continuously without losing the enantiomeric purity of the outlet streams. The present work describes the enantioseparation of the anesthetic ketamine in a semipreparative-scale SMB unit. The chiral stationary phase employed was the microcrystalline cellulose triacetate. The outlet streams were analyzed by an on-line system, composed by an UV/VIS meter and a polarimeter, and also by HPLC. The analysis indicated purity values up to 100% for the stream of interest and up to 97.7% for the other stream.
Hidden Exponent RSA and Efficient Key Distribution

In this paper we propose a variant of RSA public key scheme, called “Hidden Exponent RSA”. Based on this new scheme, we devised an efficient key distribution/management scheme for secure communication among devices in the context of pervasive computing, with emphasis on the simplicity and efficiency of the protocol. We show the new scheme is secure under the strong RSA assumption.
Ticket-based secure delegation service supporting multiple domain models

We propose a ticket-based delegation service for multiple domain models. This scheme presents an extension to the Kerberos (J.T. Kohl et al., 1991) framework using public key cryptosystem (T. ElGamal, 1985). This proposed model, based on CORBAsec (A. Alireza et al., 2000; B. Blakey, 2000), supports the protection of the high-level resources and the preservation of the security policies of the underlying resources that form the foundation of various domains, between the Kerberized domains and the nonKerberized domains. Also we achieved the flexibility of key management and reliable session key generation between the client and the provider using the public key cryptosystem based ticket.
Adherence to National Comprehensive Cancer Network guidelines for time to initiation of postoperative radiation therapy for patients with head and neck cancer

Adherence to evidence‐based treatment guidelines has been proposed as a measure of cancer care quality. The objective of this study was to determine the rate and predictors of care that does not adhere to National Comprehensive Cancer Network guidelines regarding commencing postoperative radiation therapy (PORT) within 6 weeks of surgery for patients with head and neck squamous cell carcinoma (HNSCC).
The Influence of Personality Traits on the Relationship between Work- Family Conflict and Job Satisfaction among Married Women

The role of women has changed dramatically. The claim has been supported by a general consensus among researchers that many married working women experience significant work-family conflict (WFC). However, the personality traits have been only minimally considered in the studies of WFC especially in Malaysia. To fill in this vacuum, this paper aims at investigating the influence of personality traits on the relationship between WFC and job satisfaction among employed married women by analyzing related published articles in the area. A conceptual framework is developed indicating that job satisfaction is influenced by WFC and is moderated by the Big Five personality traits. Hence, a conceptual framework is developed indicating that the dependent variable of job satisfaction is influenced by the work-family conflict. This relationship is moderated by the personality traits which taken from the framework of the Big Five Model, that is, emotional stability, extraversion, conscientiousness, agreeableness, and openness to experience. It is concluded that this paper is perhaps one of the earlier to propose that the different personality traits might have different influence on the way the married women employees manage their work-family conflict and job satisfaction in Malaysia.
Ultra-Low-Dose MDCT of the Chest: Influence on Automated Lung Nodule Detection

Objective To evaluate the relationship between CT dose and the performance of a computer-aided diagnosis (CAD) system, and to determine how best to minimize patient exposure to ionizing radiation while maintaining sufficient image quality for automated lung nodule detection, by the use of lung cancer screening CT. Materials and Methods Twenty-five asymptomatic volunteers participated in the study. Each volunteer underwent a low-dose CT scan without contrast enhancement (multidetector CT with 16 detector rows, 1.25 mm section thickness, 120 kVp, beam pitch 1.35, 0.6 second rotation time, with 1.25 mm thickness reconstruction at 1.25 mm intervals) using four different amperages 32, 16, 8, and 4 mAs. All series were analyzed using a commercially available CAD system for automatic lung nodule detection and the results were reviewed by a consensus reading by two radiologists. The McNemar test and Kappa analysis were used to compare differences in terms of the abilities to detect pulmonary nodules. Results A total of 78 non-calcified true nodules were visualized in the 25 study subjects. The sensitivities for nodule detection were as follows: 72% at 32 mAs, 64% at 16 mAs, 59% at 8 mAs, and 40% at 4 mAs. Although the overall nodule-detecting performance was best at 32 mAs, no significant difference in nodule detectability was observed between scans at 16 mAs or 8 mAs versus 32 mAs. However, scans performed at 4 mAs were significantly inferior to those performed at 32 mAs (p < 0.001). Conclusion Reducing the radiation dose (i.e. reducing the amperage) lowers lung nodule detectability by CAD. However, relatively low dose scans were found to be acceptable and to cause no significant reduction in nodule detectability versus usual low-dose CT.
Maternal perceptions of children's weight status.

BACKGROUND Several studies have addressed mothers' perceptions of their children's weight status; however, there is no investigation on Portuguese children (a country with one of the highest levels of children's overweight and obesity in Europe). The aim of this study was to quantify maternal misclassification of child weight status in a sample of Portuguese children aged 9 to 12 years, according to gender, family income, and maternal weight status, education level and age. METHODS Data were collected in a school-based study (school year 2009/2010) in northern Portugal with 499 urban children (236 girls; 47.3%). Body mass index was calculated from measurements of height and weight [body mass (kg)/height (m(2))]. Mothers' perceptions of child's weight status, age, height and weight were accessed by a questionnaire. Children's age, gender and socio-economic status were extracted from the schools' administrative record systems. Cohen's Kappa was used to analyse the misperceptions and the agreement between children's objectively measured weight status and mothers' perception of their child's weight status. RESULTS The prevalence of underweight, overweight and obesity in children was 4.6%, 25.5% and 6.4%, respectively. A proportion of 65.2% of underweight and 61.6% of overweight/obese children were misclassified by their mothers. For the majority of variables presented, the values of agreement were fair (k ranged from 0.257 to 0.486), but were statistically significant. Significant differences in the percentages of mothers who correctly classified their children's weight status were only found among the most educated in the overweight/obese group and among the normal-weight mothers in the underweight group. CONCLUSIONS Many mothers do not properly recognize their children's weight status and frequently underestimate their children's body size.
Compensation in Flow Cytometry

Many people using multi‐color flow cytometry do not understand what compensation is, when it is needed, or how it should be applied. The author provides a clear explanation of the nature of compensation, the factors that affect compensation values, and the effect of compensation on data visualization. Both hardware and software compensation are covered. Although the subject is treated from a mathematical perspective, the manner of presentation is very straightforward. The unit discusses appropriate controls and protocols to check compensation settings, as well as introducing the concept of fluorescence‐minus‐one gates. Many example figures are supplied to give the reader a clear indication of how the author believes compensation should be handled. Keywords: flow cytometry; spectral compensation; fluorescence spillover; autofluorescence; fluorescence minus one
Extinction of auditory fear conditioning requires MAPK/ERK activation in the basolateral amygdala

Whereas the neuronal substrates underlying the acquisition of auditory fear conditioning have been widely studied, the substrates and mechanisms mediating the acquisition of fear extinction remain largely elusive. Previous reports indicate that consolidation of fear extinction depends on the mitogen‐activated protein kinase/extracellular‐signal regulated kinase (MAPK/ERK) signalling pathway and on protein synthesis in the medial prefrontal cortex (mPFC). Based on experiments using the fear‐potentiated startle paradigm suggesting a role for neuronal plasticity in the basolateral amygdala (BLA) during fear extinction, we directly addressed whether MAPK/ERK signalling in the basolateral amygdala is necessary for the acquisition of fear extinction using conditioned freezing as a read‐out. First, we investigated the regional and temporal pattern of MAPK/ERK activation in the BLA following extinction learning in C57Bl/6J mice. Our results indicate that acquisition of extinction is associated with an increase of phosphorylated MAPK/ERK in the BLA. Moreover, we found that inhibition of the MAPK/ERK signalling pathway by intrabasolateral amygdala infusion of the MEK inhibitor, U0126, completely blocks acquisition of extinction. Thus, our results indicate that the MAPK/ERK signalling pathway is required for extinction of auditory fear conditioning in the BLA, and support a role for neuronal plasticity in the BLA during the acquisition of fear extinction.
Prolonged antibiotic prophylaxis after cardiovascular surgery and its effect on surgical site infections and antimicrobial resistance.

BACKGROUND Despite evidence supporting short antibiotic prophylaxis (ABP), it is still common practice to continue ABP for more than 48 hours after coronary artery bypass graft (CABG) surgery. METHODS AND RESULTS To compare the effect of short (<48 hours) versus prolonged (>48 hours) ABP on surgical site infections (SSIs) and acquired antimicrobial resistance, we conducted an observational 4-year cohort study at a tertiary-care center. An experienced infection control nurse performed prospective surveillance of 2641 patients undergoing CABG surgery. The main exposure was the duration of ABP, and main outcomes were the adjusted rate of SSI and the isolation of cephalosporin-resistant enterobacteriaceae and vancomycin-resistant enterococci (acquired antibiotic resistance). Adjustment for confounding was performed by multivariable modeling. A total of 231 SSIs (8.7%) occurred after a median of 16 days, including 93 chest-wound infections (3.5%) and 13 deep-organ-space infections (0. 5%). After 1502 procedures using short ABP, 131 SSIs were recorded, compared with 100 SSIs after 1139 operations with prolonged ABP (crude OR, 1.0; CI, 0.8 to 1.3). After adjustment for possible confounding, prolonged ABP was not associated with a decreased risk of SSI (adjusted OR, 1.2; CI, 0.8 to 1.6) and was correlated with an increased risk of acquired antibiotic resistance (adjusted OR, 1.6; CI, 1.1 to 2.6). CONCLUSIONS Our findings confirm that continuing ABP beyond 48 hours after CABG surgery is still widespread; however, this practice is ineffective in reducing SSI, increases antimicrobial resistance, and should therefore be avoided.
