High speed X-ray phase contrast imaging of energetic composites under dynamic compression

Fracture of crystals and frictional heating are associated with the formation of “hot spots” (localized heating) in energetic composites such as polymer bonded explosives (PBXs). Traditional high speed optical imaging methods cannot be used to study the dynamic sub-surface deformation and the fracture behavior of such materials due to their opaque nature. In this study, high speed synchrotron X-ray experiments are conducted to visualize the in situ deformation and the fracture mechanisms in PBXs composed of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) crystals and hydroxyl-terminated polybutadiene binder doped with iron (III) oxide. A modified Kolsky bar apparatus was used to apply controlled dynamic compression on the PBX specimens, and a high speed synchrotron X-ray phase contrast imaging (PCI) setup was used to record the in situ deformation and failure in the specimens. The experiments show that synchrotron X-ray PCI provides a sufficient contrast between the HMX crystals and the doped binde.
Individual Patient-Level Data meta-analysis: A comparison of methods for the Diverse Populations Collaboration data set

DerSimonian and Laird define meta-analysis as “the statistical analysis of a collection of analytic results for the purpose of integrating their findings. One alternative to classical meta-analytic approaches in known as Individual Patient-Level Data, or IPD, meta-analysis. Rather than depending on summary statistics calculated for individual studies, IPD metaanalysis analyzes the complete data from all included studies. Two potential approaches to incorporating IPD data into the meta-analytic framework are investigated. A two-stage analysis is first conducted, in which individual models are fit for each study and summarized using classical meta-analysis procedures. Secondly, a one-stage approach that singularly models the data and summarizes the information across studies is investigated. Data from the Diverse Populations Collaboration data set are used to investigate the differences between these two methods in a specific example. The bootstrap procedure is used to determine if the two methods produce statistically different results in the DPC example. Finally, a simulation study is conducted to investigate the accuracy of each method in given scenarios.
AN ENHANCED FREQUENT PATTERN GROWTH BASED ON MAP REDUCE FOR MINING ASSOCIATION RULES

In mining frequent itemsets, one of most important algorithm is FP-growth. FP-growth proposes an algorithm to compress information needed for mining frequent itemsets in FP-tree and recursively constructs FP-trees to find all frequent itemsets. In this paper, we propose the EFP-growth (enhanced FPgrowth) algorithm to achieve the quality of FP-growth. Our proposed method implemented the EFPGrowth based on MapReduce framework using Hadoop approach. New method has high achieving performance compared with the basic FP-Growth. The EFP-growth it can work with the large datasets to discovery frequent patterns in a transaction database. Based on our method, the execution time under different minimum supports is decreased.
The third way: philology and critical edition in the digital age

In 2006, as I prepared to begin my doctorate, I met with my supervisor-to-be to discuss prospective research topics. It became clear during the meeting that he already had a project in mind: I would produce a critical edition of the Armenianlanguage Chronicle of Matthew of Edessa, and it would be a digital critical edition. Some time later, at the celebration that followed my viva examination, my supervisor cheerfully admitted that he had not had the least idea what a “digital critical edition” might be when he had set me on the path to making one. He simply trusted that I, as a software engineer turned humanist, would figure something out along the way. The fact that I now write this suggests that I did produce something that was accepted by my supervisor and examiners as a digital critical edition. So where is it? What does it look like? And if, as recently as that, a lone doctoral student had to work out for herself what a digital critical edition should be, does it not go some way toward explaining why there are so few of them about?
Isolation of planctomycetes from Aplysina sponges

There is mounting molecular evidence that bacteria belonging to the phylum Plancto- mycetes are abundant in marine sponges including members of the genus Aplysina. In an attempt to culture planctomycete bacteria from Aplysina sponges, 116 bacterial strains were isolated on selec- tive oligotrophic media. Screening of the strain collection by fluorescence in situ hybridization with the planctomycete-specific probe Pla46 yielded 3 positive candidates. Nearly complete sequencing of the respective 16S rRNA genes revealed that the isolates were affiliated with 2 distinct clusters of the genus Pirellula: 1 isolate was obtained from a Mediterranean sponge, 1 from a Caribbean sponge and a third from Caribbean seawater. To our knowledge this is the first report of cultured Planctomycetes from marine sponges. The isolates grew slowly on oligotrophic media and failed to grow on nutrient- rich media. Pirellula sp. Strain 797 was pink-pigmented while the other 2 isolates, 16 and 81, were non-pigmented. Transmission electron microscopy revealed a pear- or droplet-shaped cell morphol- ogy that is characteristic of the genus Pirellula. The application of strain-specific oligonucleotide probes to sponge tissue cryosections showed that the isolates contribute only a minor fraction to the total microbial community that is associated with Aplysina spp. sponges.
Optically Injected Semiconductor Laser for Photonic Microwave Frequency Mixing in Radio-Over-Fiber

Nonlinear dynamics of an optically injected semiconductor laser for microwave frequency mixing are experimentally investigated. Through optical injection, the laser is driven into the nonlinear period-one (P1) dynamical state and acts as a broadly tunable photonic microwave oscillator. With an external current modulation at an intermediate frequency, the P1 oscillation is modulated accordingly, thus achieving frequency up-conversion beyond the laser bandwidth. Using a 2.5-Gbps-grade laser, binary phase-shift keying (BPSK) data signal is up-converted from an intermediate frequency of 2 GHz to a subcarrier frequency as high as 20 GHz. While the direct modulation bandwidth limits the intermediate frequency, it does not limit the subcarrier frequency. The approach uses only low-cost lasers and requires no high-speed electronic mixers.
Activity Characteristics and Emotional Experience: Predicting Boredom and Anxiety in the Daily Life of Community Mental Health Clients

Little is known about the day-to-day experience of people with mental illness. The research that has been conducted has characterized the lives of people with severe and persistent mental illness (SPMI) as largely solitary and little meaningful activity. In addition, mood states of boredom and anxiety have been implicated in the functioning of clients with mental illness in community treatment settings. The purpose of this study was to examine the daily life of people with SPMI and identify if challenge/skill qualities of activity were related to mood states of boredom and anxiety. Subjects (n = 8) were drawn from a community mental health center in a Midwestern city. Data were collected using an experience sampling method and examined at the experience level of analysis (n = 326). Logistic regression was used to examine if activity characteristics predicted boredom or anxiety. Findings indicated that the majority of subjects' time was spent in activities in which skill exceeded challenge (75.1%). Activity characteristics were found to be significant predictors of the reporting of anxiety, but were not significant predictors of boredom. Findings are discussed in terms of future research and practice.
Child Vaccination and its Impacts on Health and Health Related Matters in Noakhali Region of Bangladesh

This study was conducted to evaluate the rate of vaccination and its impacts on the children in four upazilas which were Noakhali sadar, Begumgonj, Companygonj and Chatkhil of Noakhali district. The study was carried out during the period of November 15, 2011 to December 15, 2011. Data were collected through questionnaire interviews, focus group discussions and cross check interviews. It was found that all interviewed parents of all ages and educational levels are aware about vaccination of their child. The study conducted on the rate of giving vaccines, (Tuberculosis, Polio, DPT, Measles and Hepatitis B) showed serious reactions in a few children after taking vaccine and occurrences of disease after taking the corresponding vaccine. The rate of vaccination in the four upazilas - Noakhali sadar, Begumgonj, Companygonj and Chatkhil were found to be 84, 86.6, 75.4 and 82%, respectively. No serious reactions were found among 120 children in four upazilas. Among thirty, two children suffered from Measles and one from Hepatitis B after taking the vaccine in sadar upazila. Three children suffered from Measles after Begumgonj and one suffered from Measles in Chatkhil. There were no children found to have a disease after taking the corresponding vaccination in Companygonj. Though the rate of vaccination in these areas is not so little the government should take necessary steps to ensure maximum rate of vaccination.

Options for reststrahlen materials in optical surfaces and filters

A reststrahlen material is a compound with at least partly ionic bonding. This entails that a net of alternating positively and negatively charged ion cores are arranged in a periodic pattern that constitutes the lattice of the compound. This lattice can be excited by transverse electromagnetic (EM) waves that accelerate the positive and negative ions in opposite directions. The excitation can be modeled as a damped harmonic oscillator. The oscillator has a resonance that corresponds to energy absorption. Simple considerations of ionic bonding of atomic masses in real compounds show that this resonance occurs in the infrared (IR) frequency range. In analogy with a mechanical oscillator, the resonance frequency increases with the bonding strength and decreases with the effective molecular mass [1] . An IR wave traveling through a lattice has a wavelength that is much longer than the lattice constant and the typical distances between neighboring ions. The location of this excitation in the phonon spectrum of the compound is usually associated with the transverse optical (TO) branch. Considering the long wavelength, this should be close to the origin in k-space (i.e., k�0). The frequency of the TO-branch intersecting with the frequency axis is conventionally labeled as ! T [2] . We can thus associate this molecular oscillator resonance frequency with a particular feature in the phonon spectrum of the crystal. The combined excitation of EM wave with phonon traveling through the crystal is named polariton. Using the analogy of the mechanical oscillator, which is accelerated by the electric vector of an EM wave, the classical Lorentz model dielectric function is derived [2] by ˜ "(! ) = "∞ + Ne 2
Decoquinate, lasalocid and monensin for starter feeds and the performance of holstein calves to 20 weeks of age

The large utilization of coccidiostats in dairy herds has raised the question regards the best product to use, based on better animal performance. Sixty-four Holstein calves were randomly assigned to four treatments at 10 (±4) d of age to evaluate calf performance when fed approved coccidiostats available on the market in Arizona, USA. Calves received a dry calf starter without (control) or with one of the following coccidiostats: lasalocid, 30 mg kg-1; decoquinate, 19 mg kg-1; and monensin, 30 mg kg-1. Calves received 3.6 kg d-1 of a commercial 22% CP:20% fat milk replacer until 6 wk of age. Calves were offered starter "ad libitum" up to 2 kg d-1, and calves had free access to water throughout the trial. Alfalfa hay was offered "ad libitum" after weaning. Performance and dry matter intake (DMI) were monitored for 20 weeks and broken down in different periods of measurement (0-6, 7-12 and 13-20 weeks, respectively). Despite the lower dry matter intake and weight gain for females on monensin treatment during the whole period, differences among coccidiostats were seldom observed under the conditions of this study. Good calf management and the dry, hot climate of Arizona perhaps diminished the chances for subclinical and chronic disease appearance which negated potential differences and differences in calf performances.

Use of the MMPI-I in Identifying Personality Characteristics of Anorexia Nervosa, Restrictor Subtype: A Review of the Literature.

In recent decades, the incidence of eating disorders has sharply increased. This paper reviews literature published between 1969 through 1992 which addresses personality characteristics of individuals with anorexia nervosa, restrictor subtype, utilizing the Minnesota Multiphasic Personality Inventory (MMPI-I). The current literature and research in the area of MMP. -I use and personality characteristics in anorexia nervosa is reviewed first, followed by a discussion of treatment approaches based on the MMPI-I findings on anorexic restrictors. The study's findings were inconsistent, but a general caricature for this population was presented. A chronic picture of immature, r)assive-aggressive individuals was exhibited along with depression, and social alienation, poor personality integration, clear thought disorders (such as body-image distortions), obsessionality, anxiety, low ego strength, and limited awareness of psychological problems. Researchers were also interested in treatment outcomes and several studies were interested in ,ttempting to identify personality characteristics that may indicate a better prognosis for individuals with anorexia nervosa, restrictor subtype. Restrictor anorexics who acknowledged a greater need for attention and affection may fare better than individuals with other types of eating disorders due to the former's ability to address these specific needs in treatment. Suggestions for future research are presented.

Exploring the Yelp Data Set : Extracting Useful Features with Text Mining and Exploring Regression Techniques for Count Data

We attempted to predict the number of ‘Useful’ votes a fresh Yelp review will receive using training data provided by Yelp in a recent Kaggle competition. Features were extracted from the review text with text mining techniques, and other features were created from supplementary user, business, and review data sets. We explored the use of Random Forest Regression and LASSO Regression to predict how many ‘Useful’ votes a review received. We also investigated the use of Negative Binomial Regression and Zero Inflated Negative Binomial Regression using features selected with the aid of both the trained Random Forests and the LASSO models. The different prediction techniques were then compared and analyzed.
Implementation of Static and Semi-Static Versions of a 24+8×8 Quad-Rail NULL Convention Multiply and Accumulate Unit

This paper focuses on implementing an unsigned 24+8x8 quad-rail (i.e., accumulator consists of 12 quad-rail signals, while the multiplier and multiplicand are each 4 quad-rail signals) multiply and accumulate (MAC) unit using the asynchronous NULL convention logic (NCL) paradigm. The design utilizes the array-structured algorithm for partial product summation, and is implemented and simulated in VHDL, the transistor level, and the physical level, using a 1.8 V 0.18 mum TSMC CMOS process. The MAC is realized using both static and semi-static versions of the NCL gates; and these two implementations are compared in terms of area, power, and speed.
Efficiency of the Monetary Transmission Mechanism in Croatia

This paper analyzes the efficiency of monetary policy transmission through channels of exchange rate, money stock and interest rate on real economic activity and prices in Croatia. Methodology is based on the vector error-correction model (VECM) and Johansen’s cointegration. The results indicate a long-run relation between monetary policy measures on one side and real economic activity and price levels on the other. The strongest long-run channel of monetary transmission is the exchange rate channel, while the channel of money stock is slightly weaker. The results also show an impact of the interest rate channel, which was not the case in earlier studies analyzing its impact on real economic activity.
Nocturnal Disturbances in Patients with Parkinson’s Disease

Sleep disturbances are common problems in patients with Parkinson’s disease (PD) caused by various factors including nocturnal motor symptoms, psychiatric symptoms, dementia, medication use and circadian cycle disruptions as well as comorbidity with sleep apnea syndrome (SAS), restless legs syndrome (RLS) and rapid eye movement sleep behavior disorder (RBD) (Table 1). As impaired sleep quality and sleep fragmentation due to nighttime problems are associated with daytime motor dysfunction and have a negative impact on the quality of life of the patient (Gomez-Esteban et al., 2010), an intensive and detailed evaluation of nighttime problems is warranted. Patients often may be unaware of sleep disturbances and even neurologists have been reported to fail to recognize sleep disorders in approximately 40% of PD patients (Shulman et al., 2002). Here, we review sleep disorders in patients with PD, mainly focusing on nighttime problems.
Virtual Environments...Vehicle for Pedagogical Advancement

— Virtual environments are a hot topic in academia and more importantly in courses offered via distance education. Today’s gaming generation view virtual worlds as strong social and interactive mediums for communicating and socializing. And while institutions of higher education are challenged with increasing enrollment while balancing budget cuts, offering effective courses via distance education become a valid option. Educators can utilize virtual worlds to offer students an enhanced learning environment which has the power to alleviate feelings of isolation through the promotion of communication, interaction, collaboration, teamwork, feedback, engagement and constructivists learning activities. This paper focuses on the use of virtual environments to facilitate interaction in distance education courses so as to produce positive learning outcomes for students. Furthermore, the instructional strategies were reviewed and discussed for use in virtual worlds to enhance learning within a social context .
Large Scale Image Processing in Real-Time Environments with Kafka

Recently, real-time image data generated is increasing not only in resolution but also in amount. This large-scale image originates from a large number of camera channels. There is a way to use GPU for high-speed processing of images, but it cannot be done efficiently by using single GPU for large-scale image processing. In this paper, we provide a new method for constructing a distributed environment using open source called Apache Kafka for real-time processing of large-scale images. This method provides an opportunity to gather related data into single node for high-speed processing using GPGPU or Xeon-Phi processing .
Development and validation of RP-HPLC-PDA method for the analysis of Citalopram hydrobromide in bulk , dosage forms and in in vitro dissolution samples

The objective of the current work is to develop a s imple, efficient, economical and LC-MS compatible R P-HPLCPDA method for the analysis of Citalopram Hydrobrom ide in bulk, dosage forms and in dissolution sample s. Samples were separated on Agilent Eclipse C 18 column (150 x 4.6mm, 5μm) with mobile phase compos ed f 10mM Ammonium acetate: methanol (35:65 v/v) in isocratic mode. The detection wavelength was fixed at 239nm. The retention time of Citalopram Hydrobromide was 3.1mi n and the method showed a good linearity in the concentration range of 5-25μg/mL with a correlation coefficient of 0.997. The method was validated for specificity, linearity, limit of detection, limit of quantificat ion, precision, robustness and stability. All the v alidation parameters were within the compendial requirements. The propos ed method was successfully adopted for the analysis of Citalopram Hydrobromide in bulk, pharmaceutical dos age forms and in dissolution samples.
Vocal repertoire of the New Zealand kea parrot (Nestor notabilis)

The unique alpine-living kea parrot Nestor notabilis has been the focus of numerous cognitive studies, but its com- munication system has so far been largely neglected. We examined 2,884 calls recorded in New Zealand's Southern Alps. Based on audio and visual spectrographic differences, these calls were categorised into seven distinct call types: the non-oscillating 'screech' contact call and 'mew'; and the oscillating 'trill', 'chatter', 'warble' and 'whistle'; and a hybrid 'screech-trill'. Most of these calls contained aspects that were individually unique, in addition to potentially encoding for an individual's sex and age. Additionally, for each recording, the sender's previous and next calls were noted, as well as any response given by conspecifics. We found that the previous and next calls made by the sender were most often of the same type, and that the next most likely pre- ceding and/or following call type was the screech call, a contact call which sounds like the 'kee-ah' from which the bird's name derives. As a social bird capable of covering large distances over visually obstructive terrain, long distance contact calls may be of considerable importance for social cohesion. Contact calls allow kea to locate conspecifics and congregate in temporary groups for social activities. The most likely response to any given call was a screech, usually followed by the same type of call as the ini- tial call made by the sender, although responses differed depending on the age of the caller. The exception was the warble, the kea's play call, to which the most likely response was another warble. Being the most common call type, as well as the default response to another call, it appears that the 'contagious' screech contact call plays a central role in kea vocal communication and social cohesion (Current Zoology 58 (5): 727�740, 2012).
