Plasmablastic lymphoma with initial presentation in the skin in an old patient

An 88-year-old male had progressive painful skin lesions on his left upper arm for 3 months. His medical history included hypertension, hyperlipidemia, chronic kidney disease, and coronary artery disease. Physical examinations revealed the multiple indurated erythematous nodules and plaque limited to his left upper arm [Figure 1]. There was no lymphadenopathy on both axillary and clavicular areas. He denied other systemic symptoms, including fever, body weight loss, night sweating, and changes in bowel habits. Based on suspicion of cutaneous metastasis, skin biopsy was performed.
Clinicopathologic Features of Secretory Carcinoma of Salivary Gland: An Updated Review

Secretory carcinoma of the salivary gland was first recognized in 2010 and has since been characterized by clinical, pathologic, and genetic means. Tumors share morphologic, immunophenotypic, and genetic features with primary breast secretory carcinoma,which facilitated its recognition as a distinct salivary entity. Definitive diagnosis is based on the characteristic immunophenotype of S100 and mammaglobin positivity and the presence of theETV6-NTRK3 fusion gene; these features have allowed reclassification of tumors most frequently originally classified as acinic cell carcinoma variants. We present a case of secretory carcinoma that was reclassified from cystadenocarcinoma using immunohistochemical and molecular testing and present an updated review of the clinicopathologic features with discussion of differential diagnosis.
A study of physical anhedonia as a trait marker in schizophrenia

Background: Inability to define the heritable phenotype might be a reason for failure to replicate results in psychiatric genetics. Hence, the use of a candidate symptom approach to identify more homogeneous forms of diseases among affected individuals and subclinical traits among first-degree relatives (FDRs) may increase genetic validity. The objective of the present study was to determine whether physical anhedonia can be used as a marker for individuals at risk of schizophrenia. Materials and Methods: Physical anhedonia scores (measured using Revised Physical Anhedonia Scale [rPAS]) were compared across thirty remitted schizophrenic patients, thirty of their unaffected FDRs, and thirty healthy controls. We compared anhedonia scores among the three main groups using one-way ANOVA. Results: Physical anhedonia (rPAS) scores of the schizophrenic patient group were significantly higher than that of their FDRs and controls both, and physical anhedonia (rPAS) scores of FDRs were significantly higher than that of healthy controls (F = 115.33, P < 0.001). The subgroups did not differ on various other clinical characteristics. Conclusion: Our data suggest that physical anhedonia is a candidate symptom for schizophrenia.
Comparison of Perinatal Outcomes of Singletons Following Vanishing Twin Phenomenon and Singletons with Initial Single Gestational Sac Conceived Following Assisted Reproductive Technology: A Retrospective Analysis

Aim: The aim of the study was to compare the perinatal outcomes between singletons following vanishing twin phenomenon and singletons arising from initial single gestational sac following assisted reproductive technology (ART) treatment. Setting and Design: This was a retrospective cohort study. Materials and Methods: A retrospective cohort study included analysis of all singleton births following ART over a period of 7 years (January 2010 –December 2016). All women who underwent fresh or frozen embryo ART cycles were followed up. The study population included all singleton births following spontaneous reduction of one of the gestational sacs in dichorionic diamniotic twin pregnancies. The perinatal outcome of this group was compared with those of singletons arising from the initial single gestational sac. Results: A total of 521 singleton births were recorded during the study period. In the study group, 72 singleton births had spontaneous reduction of one of the gestational sacs (vanishing twin group) and the remaining 449 had an initial single gestational sac. The risk for low birth weight (LBW) (14/72, 19.4% vs. 96/449, 21.6%) and preterm birth (PTB) (17/72, 23.6% vs. 134/449, 29.8%) was not significantly different between those singletons who had spontaneous reduction from two gestational sacs to single sac compared to those with initial single sac. The miscarriage rate was significantly lower in vanishing twin group compared to control group (7/84, 8.3% vs. 157/622, 25.2%; P = 0.01). The subgroup analysis based on spontaneous reduction occurring before or after the appearance of the embryonic pole also showed similar risk of PTB (11/41, 26.8.% vs. 9/31, 29.0%) and LBW (7/41, 17.1% vs. 9/31, 29.0%). Conclusion: Perinatal outcomes in singleton live births following vanishing twin phenomenon are similar to those pregnancies with an initial single gestational sac following ART.
Creating Stop-Motion Videos with iPads to Support Students’ Understanding of Cell Processes

Abstract The purpose of this qualitative case study is two-fold: (a) describe the implementation of a stop-motion animation video activity to support students’ understanding of cell processes, and (b) present research findings about students’ beliefs and use of iPads to support their creation of stop-motion videos in an introductory biology course. Data indicated that students used the devices extensively to access, seek, and share information related to cell processes, which led to their increased familiarity with using the iPad to support their learning. Using iPads and apps enriched students learning experiences by providing them with a creative way to demonstrate their understanding of content, enhanced their communication skills, and provided them with an alternative means for gathering and sharing supplementary resources.
Academic Spanish during mathematics instruction : the case of novice bilingual teachers in elementary classrooms

This dissertation focused on the study of the Spanish academic language proficiency of novice bilingual teachers during the act of teaching mathematics in elementary grades. Four first year teachers in a large urban school district in central Texas participated in the study. At the time of the study two participants were fully certified and had attended four-year teacher preparation programs. The additional participants had completed all certification requirements including content examinations and the Texas Oral Proficiency Test (TOPT); they were completing their certification requirements through alternative certification programs. The study sought to identify the moments in their teaching of mathematics in Spanish when their instruction broke down, i.e. when they appeared unable to communicate ideas to students, and the reasons for these breakdowns.
Interdisciplinarity in Education Research

Abstract Citation analysis of dissertations was used to explore the interdisciplinary nature of education graduate students' research. A sample of curriculum and instruction dissertations, and their bibliographies we studied using citation analysis methods and analysis of Digital Dissertation records. Research methodologies were also explored. Rather than crossing broad disciplinary boundaries, interdisciplinary work for these students occurred at the level of specific fields of study within curriculum and instruction, and at times education subdisciplines. Questions are raised about the nature of interdisciplinarity in graduate student work. As faculty research and academic structures continues to evolve, graduate student work also may change.
Analysis of connectivity between local multi-variate patterns of functional MRI data

During the last century, many innovations in medicine, chemistry, and physics allowed a deeper insight into organization and functionality of the brain. One of the newest of these methods is functional magnetic resonance imaging (fMRI), which, compared to other techniques, achieves a high spatial resolution. Aim of this thesis is to introduce, illustrate, and discuss a new way of investigating connections between brain areas using fMRI data. The key idea of this thesis is to replace the state of the art representation of a brain region's temporal behavior by its first PCA component with time-series associated to multi-variate patterns (MVP) of a region. Now each region can be represented by several time-courses, each one associated with the activation of a multi-variate pattern of the area. To identify multi-voxel patterns and their activation courses, independent component analysis (ICA) was used. During my thesis, this concept is referred to as pattern connectivity. Pattern connectivity states not only a generalization of the existing method, but also yields a more intuitive representation of brain regions and allows to map and study more complex behaviors of brain regions. The analysis of two fMRI experiments and synthetic fMRI data illustrates the proposed method. The first experiment validated pattern connectivity by comparing it to the state of the art method. The second experiment in which the behavior of one of the regions can not be represented by a single time course is described. Here, pattern connectivity was able to validate an intuitive hypothesis about underlying connections. In addition, pattern connectivity revealed the used connectivity structure used to generate a synthetic fMRI data set. The major goal of the present work was to show that, for fMRI data, it is possible to study neuronal connectivity between multi-voxel patterns instead of brain regions by providing, validating, and illustrating the new concept of pattern connectivity, and by identifying and solving problems arising with its implementation.
Combining fuzzy vector quantization and neural network classification for robust isolated word speech recognition

The issue of robust isolated word speech recognition in cases where the input signal is corrupted by acoustic noise, is addressed with a new fuzzy vector quantization (FVQ)/neural network scheme. The proposed system combines in a simple and effective way the fuzzy classification capability of FVQ with the non-linear pattern discrimination power of the multi-layer perception (MLP) neural network. The paper thus defines the design and algorithmic operation of this system and compares its recognition performance to that of a conventional FVQ/hidden Markov model (HMM) system. Computer simulation results obtained using speech corrupted by car or white noise indicate that FVQ/MLP provides significantly better performance than FVQ/HMM. <<ETX>>
Avian diversity in forest gaps of Kibale Forest National Park, Uganda

We studied gap avifaunal diversity in eight forest gaps within Kibale National Park using point counts. A total of 348 individuals comprising 55 species were recorded. A species-accumulation curve showed that, although not all possible species were recorded, this was a reliable representation of the entire gap avian diversity of Kibale forest. Next, we categorized the observed avifauna in terms of forest dependence and feeding guilds. Whereas the proportions based on forest-dependency were significantly different from the expected proportions when considering the avian community for the entire forest, those based on feeding guilds were not. Gap size and vegetation cover density both had positive correlations with species richness and abundance, though not always statistically significant. This study shows that gaps significantly contribute to the overall avian species richness of Kibale forest. This could be either through supporting entirely different species, or providing a burst of new resources that enables forest species to extend their home ranges or live at higher densities.
A grammar of Mosetén

This book provides the first published and accessible grammatical description of a Mosetenan language. The authors carried out extensive fieldwork on the language, and the grammar is based on text data such as stories and discussions, as well as elicitation data. It is innovative in being the first accessible description of this small, unclassified language family and gives important insights into the grammar. It has been reviewed in Anthropological Linguistics 48 (2) 2006 by Willem Adelaar, LinguistList 19.4. 2005 by Olesya Khanina and International Journal of American Linguistics 73 (2007) by Andres Pablo Salanova.
The properties of LPcvd Si/sub 3/N/sub 4//SiO/sub 2/ film electret based on silicon

By means of the technology of LPcvd and thermal oxidation the Si/sub 3/N/sub 4//SiO/sub 2/ double-layer electret film was prepared on different doped silicon wafers. The experimental results show that the Si/sub 3/N/sub 4//SiO/sub 2/ double-layer film possesses a good storage ability of negative charges after modifying the surface with HMDS, and all of the charges were almost trapped in the bulk of upper layer Si/sub 3/N/sub 4/ film. In addition, the TSD spectra of Si/sub 3/N/sub 4//SiO/sub 2/ film were influenced greatly by the differences of the dopants in the silicon wafers.
Hand-off traffic modelling in cellular networks

From a teletraffic analysis point of view, hand-off traffic is the main distinguishing feature between fixed (POTS) telephone networks and mobile telephone networks. In earlier macro-cellular network analysis, hand-off traffic was generally modelled as a Poisson process. With the present-day proliferation of micro-cellular networks, mobiles may request for hand-off many times at many different cellular boundaries and therefore undergo a series of hand-offs that may alter their traffic profile. The Poisson assumption may no longer be valid for calls that have been handed off a great many times. We model hand-off traffic using the mean and the variance of its probability distribution. We attempt to capture the change in traffic profile that occurs during the hand-off process. We show that hand-off traffic is in fact a smooth traffic process and that the two moment representation of hand-off traffic is superior to the single moment representation.

In view of the necessityof requiring somethingmore than the knowledge that a form of treatmentis being adoptedby many practitioners,we approachthe subject of the induction of nitrous' oxide-oxygen analgesiaand anresthesiain obstetrics with caution and a little misgiving. It is largely usedin America; in the British Empire the majority of obstetricians have found ehloroform safe and easyto apply. , The medical profession,will not easily forget the amount of charlatanry that was associatedwith the injection of morphine and scopolaminefor the purpose of inducing a state of drowsinessand amnesia,unfortunately named"twilight sleep. "l The National AnsesthesiaResearchSociety of America hasrecently publisheda very artistic and attractivemonographin nine chaptersand an appendix.in which is set forth all the arguments"and data available in 'favour of nitrous oxide-oxygenanalgesiafor normal child-birth and anmsthesiafor obstetric operations. 2 A great many words are wastedon the subject of the desirability of using somemeansfor removing the suffering of child-birth. No one seriously contendsto-day that there is a valid objection to the relief of pain. It is, however,agreedthat the relief of suffering may not lessen the'efficiency of the uterine contractions nor exclude the aid which the parturient woman is capableof exercising in the expulsion of the child. Very much space is allotted to a discussionof the safety of nitrous-oxide-oxygenaaalgesiaand antesthesia,if properlyadministered. For those whodetermine to employ this meansof reducingor eliminating suffering in child-birth, we can cordially recommend the chaptersdevotedto the techniqueof the administration. The writers are expert and their guidance is safe and explicit. In the next place. the relative toxicity of 'chloroform and nitrous oxide is important in many respects,but is not a determiningfactor in the selection of the one or other for this special purpose. It may be admitted'that there is some experimentalevidenceto show that chloroform may produce degenerativechangesin the tissuesof both mother'and fostus. It is claimed by the writers that these changes persist for a considerable time in laboratoryanimals. Levy has found that chloroform may be the exciting causeof death. British obstetricians claim that when administeredwith care and skill, chloroform does not cause death in labour. The writers fail to adduce convincing evidence of definite damageto either the mother or her infant producedby chloroform administeredwith care during the birth. They are in dangerof alienating enthusiasmfor this methodby putting up the bogey of the danger of chloroform ansesthesiain child-birth. Jn regard to the ease with which the depth of the analgesia'and anresthesiacan be varied when nitrous oxide-oxygen admixture is used, much information,is given. There is no doubt that it is advantageousto employ a substancewhich canyield any desired degree of narcosis from the faintest dis-
A technique for measuring the level of autonomicity of self-managing systems

Autonomic and self-managing systems are increasingly pervasive across an ever-widening spectrum of application domains. Autonomic technology is advancing at a high rate, yet there are no universal standards for the technology itself and the design methods used. There are also significant limitations to the way in which these systems are validated, with heavy reliance on traditional design-time techniques, despite the highly dynamic behaviour of these systems in dealing with run-time configuration changes and environmental and context changes. These limitations ultimately undermine the trustability of these systems and are barriers to eventual certification. This paper is concerned with setting the groundwork for the introduction of standards for Autonomic Computing (AC), in terms of technologies and the composition of functionality as well as validation methodologies. We propose that the first vital step in this chain is to introduce robust techniques by which the systems can be described in universal language, starting with a description of, and means to measure the extent of autonomicity exhibited by a particular system. We present a novel technique for measuring the Level of Autonomicity (LoA) along several dimensions of autonomic system self-CHOP (self-configuration, self-healing, self-optimisation and self-protection) functionalities.
An In Situ Study of Analogical Reasoning in Novice and Experienced Design Engineers

This paper describes a study to understand the use of analogies by design engineers with different levels of experience in an adaptive design domain. Protocol analyses of 12 design engineers have been analyzed to understand the functions and reasoning of the analogies. The protocols are real-world data from the aerospace industry. The findings indicate a significant difference in both the use of analogies by novices and experienced designers and the reasoning from the analogies. Novices were found to predominantly transfer information related to the geometric properties without explicit reference to relevant design issues or to the appropriateness of applying the analogy, whereas experienced designers tended to use analogies for problem solving and problem identification. Experienced designers were found to use the analogy to reason about the function of a component and the predicted behavior of the component, whereas the novices seem to lack such reasoning processes.
Action potential detection by non-linear microscopy

In this work, we combined the advantages of second-harmonic generation (SHG) with a random access (RA) excitation scheme to realize a new microscope (RA-SHG) capable of optically recording fast membrane potential events occurring in a wide-field configuration. The RA-SHG microscope in combination with a bulk staining method with FM4-64 was used to simultaneously record electrical activity from clusters of Purkinje cells (PCs) in acute cerebellar slices. Spontaneous electrical activity was also monitored simultaneously in pairs of neurons, where APs were recorded in a single trial without averaging. These results show the strength of this technique to describe the temporal dynamics of neuronal assemblies.
Computer Anxiety and Different Types of Computer Courses

This study was undertaken for two purposes: 1) to describe differences in anxiety in students voluntarily entering two different types of computer courses; and 2) to assess the changes in anxiety level attributed to each course. Undergraduate college students had registered for two introductory computer courses. One was a problem solving and programming course; the other was a tools software applications (non-programming) course. Students completed a pretest and posttest for computer anxiety. Results indicated that initial anxiety levels were not significantly different, and that the reduction in computer anxiety was significantly greater for students in the tools software applications course than for students in the problem solving and programming course. Although the “tool use” course proved more effective in reducing computer anxiety, results showed that large numbers of subjects in both conditions exhibited no reduction in anxiety as a result of the courses.
Simulation Modeling Handbook: A Practical Approach

From the Publisher: Simulation modeling is becoming increasingly popular as a technique for evaluating the performance of resource allocation and alternate operating policies. It is a cost-effective method for improving process performance and can be used to evaluate the performance of capital equipment before making an investment. This handbook is a practical, easy-to-follow reference that provides up-to-date knowledge and offers step-by-step procedures for conducting simulation studies that help decision-makers find the optimal courses of action. Unlike most other books on the subject, this presentation is independent of any particular simulation software, allowing readers to use any commercial package or general purpose programming language.
