Rehabilitation in aphasia: Using brain and behavioural measures to investigate the effects of a digital speech comprehension therapy

This thesis investigates the development and testing of a novel tablet-based speech comprehension therapy, for persons with chronic aphasia (PWA). // In Chapter 1 of this thesis, I present a qualitative study on the development of a speech comprehension therapy app (Listen-In), with gamification. Five co-design focus groups were carried out, resulting in an iterative cycle of prototype development. Using thematic analysis, a number of barriers to usability and enjoyability were identified. This resulted in a multitude of design changes, which led to a final product suitable to be self-administered by patients. // In Chapter 2, I analysed data from a cross-over clinical trial of Listen-In (N=35), which compared 12-weeks of Listen-In treatment with 12-weeks of standard care. These findings showed: (i) PWA made large and significant gains in speech comprehension for words trained during treatment; (ii) gains were item specific, suggesting facilitation of item-specific networks; (iii) a combination of baseline measures explained only a small amount of variability in treatment outcomes. // In Chapter 3, I used voxel-based morphometry (VBM) to investigate whether baseline structural integrity contributed to treatment outcomes, in a subgroup of patients (N=25). I found that greater volume of mainly white matter, in distributed regions in the right hemisphere, predicted greater response to treatment. I speculated that these regions related to multi-functional networks supporting a range of cognitive and language functions. // In Chapter 4, I used longitudinal VBM to investigate therapy-driven structural neuroplasticity in the same subgroup of patients. I found that greater improvements in comprehension of treated items, were related to tissue changes in bilateral temporal lobes, in key speech processing regions. // In the final discussion section, I interpret these key findings, their clinical implications, and directions for future research.
Comparison of 850 nm VCSEL oxide aperture designs

We design, produce, characterize, and compare 850 nm vertical cavity surface emitting lasers (VCSELs) with one and two oxide aperture layers, and with cavity optical thicknesses of 0. 5λ and 1. 5λ. We process five VCSEL wafers side by side with varying oxide aperture diameters from about 4 to 16 m and perform on-wafer static and dynamic testing. From optical output power-current-voltage characteristics we extract and compare threshold currents, differential series resistances, and wall plug efficiencies. We measure the dynamic 2-port scattering parameters (S11 and S21) to determine the small signal modulation frequency response of the VCSEL and the combined VCSEL and photodetector optical link. By extracting and comparing the D-factor, modulation current efficiency factor, -3 dB bandwidth, and resistanceinductance- capacitance (RLC) circuit elements we find only a small difference in the static and dynamic performance characteristics of the five VCSEL designs, with slightly higher bandwidth for the half-lambda cavity VCSELs with two top oxide apertures.
Development and preliminary experimental results of a high-temporal-resolution terahertz solid-source interferometer on EAST

A vertical viewing 0.65 THz Solid-state Source Interferometer (SSI) has been installed for line-integrated density measurements on Experimental Advanced Superconducting Tokamak (EAST) . The SSI utilizes two independent solid-state diode sources with 2 mW output power and a base frequency multiplier, which provides a wide range of Intermediate Frequencies (IF) . The high time resolution of 0.1 μs at a 10 MHz IF has been successfully achieved. The IF signal remains almost constant for several hours without any active frequency stabilization. A sensitivity in the integrated density of 0.77× 1016 m−2 has been obtained. The density measurement has been implemented with IF ∼ 0.85 MHz, in a plasma with Ip=600 kA and PLHW=2.1 MW on EAST . The line-averaged density, 3.5× 1019 m−3, measured by the SSI shows good agreement with the results measured by the HCN interferometer system and the POlarimeter-INTerferometer (POINT) system in the same discharge.
Responding to the neoliberal and managerial changes: a generational perspective of Chinese academics

ABSTRACT Although all Chinese academics from different generational cohorts are increasingly subjected to a variety of specific institutional practices and technologies, each generational group is distinctive in terms of its opportunities and constraints, and each one understands, experiences and responds to the neoliberal and managerial reforms in quite different ways. Informed by in-depth interviews from a generational perspective with 32 participants, this study explores the generational differences in university academics’ responses to the neoliberal and managerial discourse by taking into account the specific context of Chinese universities. The findings first introduced the different conditions, opportunities and constraints that each generation faces, then interpreted the different values and beliefs that different academic generations hold about their academic work. Finally, the individual reactions and actions of each generation resulting from the possibilities, constraints and interpretations of the neoliberal and managerial reforms were delineated. This study concluded with some practical implications to facilitate different generational cohorts of Chinese academics adapting to the changing environment.
Identifikasi Tweet Hoax Yang Berhubungan Dengan Pemilihan Presiden 2019 Menggunakan Naïve Bayes Classifier

Abstrak Hoaks merupakan berita yang tersebar tanpa tahu kebenarannya atau faktanya. Hoaks biasanya tersebar melalui media yang mudah diakses seperti media sosial facebook, twitter dan lain-lain. Terutama pada masa pemilihan presiden (pilpres), para pasangan calon presiden dan wakil presiden tersebut memanfaatkan media sosial untuk melakukan kampanye. Hal ini tentu dimanfaatkan oleh orang-orang yang tidak bertanggung jawab untuk menyebarkan berita hoaks. Oleh karena itu perlu adanya pengidentifikasian tweet-tweet hoaks yang berhubungan dengan pemilihan presiden 2019 agar masyarakat dapat terhindar dari berita hoaks. Metode yang digunakan untuk identifikasi hoaks adalah Naive Bayes Classifier (NBC). Metode NBC dipilih karena telah terbukti efektif untuk kategorisasi teks, prosesnya sederhana, cepat dan akurasi klasifikasi yang tinggi. Data tweet yang digunakan sebanyak 500 tweet dengan 143 tweet hoaks dan 357 tweet bukan hoaks. Hasil menunjukkan bahwa NBC dengan tambahan seleksi fitur Mutual Information (MI) dan Information Gain (IG) dapat menghasilkan nilai precision sebesar 0.9146, recall sebesar 0.9146, dan F1 score sebesar 0.9433 sedangkan NBC tanpa seleksi fitur menghasilkan nilai precision sebesar 0.6932, recall sebesar 0.9531, dan F1 score sebesar 0.8026, dengan kata lain seleksi fitur dapat menambah nilai F1- score sebesar 0.1408. Kata kunci: hoaks, pemilihan presiden, tweet, Naive Bayes Classifier. Abstract Hoax are news that is spread without knowing the truth or the facts. Hoax are usually spread through easily accessible media such as Facebook, Twitter and others. Especially during the presidential election, the pair of candidates for president and vice president used social media to carry out campaigns. This is certainly used by people who are not responsible for spreading hoax news. Therefore, it is necessary to identify hoax tweets related to the 2019 presidential election so that people can avoid hoax. The method used for hoax identification is Naive Bayes Classifier (NBC). The NBC method was chosen because it has been proven effective for text categorization, the process is simple, fast and has high classification accuracy. The tweet data used was 500 tweets with 143 hoax tweets and 357 non-hoax tweets. The results show that NBC with additional Mutual Information (MI) and Information Gain (IG) feature selection can produce a precision value of 0.974, a recall of 0.9146, and an F1 score of 0.9433 while an NBC without a feature selection produces a precision value of 0.6932, a recall of 0.9531, and F1 score of 0.8026, in other words feature selection can increase the value of F1-score of 0.1408. Keywords: hoaks, presidential elections, tweets, Naive Bayes Classifier.

Expert Views, Opinions, and Recommendations: Are Graduate-Level Nurse Practitioner Programs Offering Adequate Dermatology Preparation to Students Entering Primary Care?

Purpose The purpose of this study is to understand how well and to what extent nurse practitioner (NP) graduate programs prepare students to recognize and manage dermatologic conditions in the primary care setting based on the views and opinions of expert dermatology NPs, obtained through the use of an open-ended questionnaire. Background Studies have shown that NPs practicing in primary care have difficulty recognizing, diagnosing, treating, and managing dermatologic conditions. Confusion exists concerning what and when to refer to a specialist. Few peer-reviewed articles exist pertaining to the dermatologic preparation of NP students and whether a lack of preparation precipitates this phenomenon. Aim The aim of this study was to analyze response data to identify an emergent hypothesis to be used as a basis for further research on this topic. Methods Eight open-ended questions were sent to 15 dermatology nurse experts, of which nine responded. They were assigned random identifiers, and their answers were interpreted using thematic analysis and emergent theory. Results The emergent hypothesis indicated that experts in the field of dermatology nursing recognize a need for expanded dermatology preparation for NP students in graduate programs. Several reasons were provided, and recommendations were given. Discussion Deficiencies in the level of dermatologic knowledge necessary to competently treat patients with skin conditions in primary care settings are not a phenomenon isolated to NP practice. Similar challenges are found in the literature relating to primary care physicians and physician assistants. NPs have an opportunity to be leaders in this area of clinical and didactic preparation for future practitioners. Conclusion Expanding dermatology preparation at the graduate NP level is necessary and will improve primary care patient outcomes as well as educational standards within the NP community.
Bowerbirds’ Mate-Selection Contests

In the world of satin bowerbirds, the male-birds engage in a contest among themselves to win their mates: they spend considerable time and effort in decorating their own bowers, and then attempt to destroy the decorations of their rivals’ bowers. The female-birds, in turn, select their mates on the basis of the attractiveness of the best surviving bowers. We study a game-theoretic model of such a mating contest, where two male-birds of distinct strengths engage in competitive signaling with value-less signals followed by signal sabotage (in an environment where a female-bird infers a male-bird’s strength by observing the quality of his surviving bower). We prove that sabotage possibilities can improve the outcomes for both male-birds – since anticipated threat of sabotage depresses each male-bird’s incentive to engage in costly signaling, while harming the outcome for the female-bird – as sabotage introduces noise in the female-bird’s selection process.
A Linearly Optimization Method for Slam Estimation Based on Stereo Features

: Recently graph based SLAM has become a popular representation for solving SLAM problem but it is affected by its inherent nonlinearity due to noisy measurements and reprojection errors which lead to non-consistent map. The proposed system provides the entire robot trajectory at lower cost using stereo camera, generates a globally consistent 3D map and provides linear graph optimization. We show that the validation of our system based on stereo camera which utilizes a linear optimization method which provides only one accurate solution in contrast to the well-known nonlinear global optimization like BA of ORB-SLAM which provides multiple non-accurate solutions for optimization. Furthermore, our system runs in real time and is 3X faster than the current state-of-the-art SLAM systems for stereo SLAM. Our system gives comparable accuracy compared with the state of the art. We tested our system using KITTI data sets. We show that our system can be an alternative to bundle adjustment approaches with a better accuracy, robustness and more efficient than some well-known systems.
Bacterial chemoattractant synergizes with LPS to induce inflammation via upregulating TLR4

The principal challenge for the host is to efficiently detect the invading pathogen and mount a rapid defensive response. Leukocytes recognize invading pathogens by directly interacting with pathogen-associated molecular patterns via Toll-like receptors (TLRs) expressed on the leukocyte surfaces. In the present study we show for the first time that fMLP synergized with LPS to induce an inflammatory response via up-regulation of TLR4 in vitro and in vivo. Moreover, we show that fMLP-induced TLR4 up-regulation was mediated by FPR and Gi/Go class of heterotrimeric G proteins. Interestingly, low molecular weight GTPase Rho A acted as a regulator for FPR-mediated TLR4 induction, thereby implying a critical role for Rho A GTPase in inflammatory response during bacterial infection. Our data indicate a possible important role of fMLP that bacterial chemoattractant fMLP not only attracts leukocytes but also contributes directly to inflammation by synergizing with bacterial LPS.
Diversity and Habitat Distributions of Ground-Surface Spiders (Araneae) in Kings Mountain National Military Park, South Carolina

Abstract We surveyed ground-surface spider populations in Kings Mountain National Military Park, Blacksburg, SC, monthly from August 2009 through July 2010 using pitfall traps to collect spiders at 2 sites in each of 3 forest habitat types: riparian zones, dry forest areas, and ridgetop habitats. Of the 902 adult spiders collected, we identified 848 to species, representing 85 species in 22 families. Although each habitat type supported a unique set of species, each also shared species with the other habitat types. High Chao–Sorenson similarity values were seen in comparisons of both forest and ridgetop as well as forest and riparian habitats. We used the first 3 Hill numbers, species richness (0D), Shannon exponential (1D), and inverse Simpson (2D) indices, to compare diversity among habitat types. Species richness was significantly higher in the riparian compared to the ridgetop habitat, while both the Shannon exponential and inverse Simpson indices were significantly higher in the riparian habitat than in either the forest or ridgetop habitats, which did not differ from each other. Diversity was not significantly different between any pairs of sites within habitats with the exception of coverage-based species richness in the dry forest habitat. Within a habitat type, the 2 forest sites had the highest Chao–Sorenson similarity value, followed by the 2 ridgetop sites, with the 2 riparian sites being the least similar to each other.
Co‐incorporation of Chinese milk vetch (Astragalus sinicus L.) and rice (Oryza sativa L.) straw minimizes CH4 emissions by changing the methanogenic and methanotrophic communities in a paddy soil

The practice of co‐incorporating rice straw and leguminous green manure (such as Chinese milk vetch) into paddy soils has become increasingly popular in the last 10 years, although its effect on soil CH4 emissions and microbial community structure is poorly understood. In this study, data from a 2‐year pot experiment were used to reveal the effects of the co‐incorporation of rice straw and Chinese milk vetch on CH4 emissions and methanogenic and methanotrophic communities in paddy soil. Five treatments were chosen: CK (unamended control), CF (inorganic fertilizer), FM (inorganic fertilizer and Chinese milk vetch, 20 g 10 kg−1 dry soil, 4.5 t ha−1), FR (inorganic fertilizer and rice straw, 20 g 10 kg−1 dry soil, 4.5 t ha−1) and FMR (inorganic fertilizer and Chinese milk vetch and rice straw mixture, 5 + 15 g 10 kg−1 dry soil, 1.125 + 2.375 t ha−1). Overall, the soil CH4 emissions in the 2 years under all residue treatments (104.4–122.8 and 83.3–133.3 g CH4 m−2) were higher than those in CK (57.0 and 20.7 g CH4 m−2) and CF (71.8 and 21.9 g CH4 m−2) treatments. The FMR treatment decreased CH4 emissions when compared with FM and FR, especially in the second year. A higher abundance of methanogens (mcrA gene copies) was found under the plant residue‐treated soils (4.35 × 108 g−1 dry soil on average) and FM increased the abundance of methanotrophs (pmoA gene copies, 2.68 × 106 g−1 dry soil). Application of plant residues changed the methanogenic and methanotrophic community structures in comparison with CF (e.g., markedly increased the populations of Methanobacteriales and Methylomonas and suppressed Methanomicrobiales and Methylobacter populations). Methane emissions were significantly and positively related to the mcrA and pmoA gene copy numbers, as well as the mcrA/pmoA ratio. The partial least squares path model (PLS‐PM) indicated that the rice plant biomass (path coefficient = 0.64), the abundance of methanogens (path coefficient = 0.57) and the community structure of methanotrophs (path coefficient = −0.59) were determinants of CH4 emissions. Among the three residue‐treated soils, FMR showed the lowest CH4 emissions and was associated with a slight decrease in the mcrA/pmoA ratio and a significant increase in the Type I/Type II methanotrophs ratio. Thus, we recommend the co‐incorporation of Chinese milk vetch and rice straw as a sustainable fertilization pattern to improve the growth of rice and minimize CH4 emissions.
Detachable Magnet Retained Cheek Plumpers To Enhance Complete Denture Esthetics - A Case Report. -

Edentulism leads to collapse of the facial tissues resulting in a sunken appearance of the cheeks causing a negative psychological impact on well-being of a patient. Use of dentures to some extent can restore the loss but in some cases additional support is required. This clinical report discusses a simple non invasive technique to provide support for sunken cheeks using detachable acrylic cheek plumpers, retained using iron–neodymium close-field magnets. Magnets retained cheek plumper is a modification of the conventional technique of supporting the slumped tissues.
Financial Constraint, Property Right and Cost of Capital

This paper examines the impact of financing constraint risk on the cost of equity capital, and finds that there is a significant positive correlation between the financing constraint risk and the cost of equity capital. The greater the financing constraint risk is, the greater the cost of equity capital is, and state-owned enterprises can mitigate the impact of financing constraint on the cost of equity capital. For companies that do not disclose the protection of shareholders’ equity in the annual report, their financing constraint risk has an impact on the cost of equity capital. The influence of cost is more significant.

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service for their processing from a common CS. Also, the problem of the optimum offloading is considered as an optimization problem with optimization parameters including communication resources (such as bandwidth, transmit power and backhaul link capacity) and computational resources (such as the capacity of cloud server) in the downlink network. The main goal is to minimize the total energy consumption by mobile users (MUs) for processing with the delay limitation for each use. This issue leads to a non-convex problem and to solve the problem, we use successive convex approximation (SCA) method. We finally show that the joint optimization of these parameters leads to reducing the energy consumption of the network with simulation examples.
