THE WINDS OF O-TYPE STARS: IONIZATION STRUCTURE AND REVISED STELLAR PARAMETERS FROM FAR-UV SPECTRA

We derived consistent photospheric and wind parameters of O-type stars, by analyzing high-resolution spectra in the range 905 to 3250 A with line-blanketed, hydrodynamic, non-LTE spherical models. We nd signicantly lower Te and luminosities than previously assigned to these spectral types. We show sample results from a comprehensive program to study hot massive stars in the Milky Way (MW) and Local Group galaxies. Stellar parameters are derived by a consistent analysis of multiwavelength spectra, with non-LTE, hydrodynamic, lineblanketed models. We combine FUSE spectra (905 to 1187 A) and IUE/HST archive spectra (1150 to 3250 A). Synthetic spectra for the analysis are computed with the WMBASIC code (Pauldrach, Homan, & Lennon 2001), and with Hillier & Miller’s (1998) CMFGEN code for comparison.
Influence of viscosity contrast on buoyantly unstable miscible fluids in porous media

The influence of viscosity contrast on buoyantly unstable miscible fluids in a porous medium is investigated through a linear stability analysis (LSA) as well as direct numerical simulations (DNS). The linear stability method implemented in this paper is based on an initial value approach, which helps to capture the onset of instability more accurately than the quasi-steady-state analysis. In the absence of displacement, we show that viscosity contrast delays the onset of instability in buoyantly unstable miscible fluids. Further, it is observed that by suitably choosing the viscosity contrast and injection velocity a gravitationally unstable miscible interface can be stabilized completely. Through LSA we draw a phase diagram, which shows three distinct stability regions in a parameter space spanned by the displacement velocity and the viscosity contrast. DNS are performed corresponding to parameters from each regime and the results obtained are in accordance with the linear stability results. Moreover, the conversion from one dimensionless formulation to another and its importance when comparing the different type of flow problem associated with each dimensionless formulation are discussed. We also calculate ${\it\epsilon}$ -pseudo-spectra of the time dependent linearized operator to investigate the response to external excitation.
Representation Learning on Brain MR Images for Tumor Segmentation

MRI is favorable for brain imaging due to its excellent soft tissue contrast and absence of harmful ionizing radiation. Many have proposed supervised multimodal neural networks for automatic brain tumor segmentation and showed promising results. However, they rely on large amounts of labeled data to generalize well. The trained network is also highly specific to the task and input. Missing inputs will most likely have a detrimental effect on the network’s predictions, if it works at all. The aim of this thesis work is to implement a deep neural network that learns the general representation of multimodal MRI images in an unsupervised manner and is insensitive to missing modalities. With the latent representation, labeled data are then used for brain tumor segmentation. A variational autoencoder and an unified representation network are used for representation learning. Fine-tuning or joint training was used for segmentation task. The performances of the algorithms at the reconstruction task was evaluated using the meansquared error and at the segmentation task using the Dice coefficient. Both networks demonstrated the possibility in learning brain MR representations, but the unified representation network was more successful at the segmentation task.

The Role of Corticothalamic Feedback in the Response Mode Transition of Thalamus

—Thalamus is the relay station for most sensory information between peripheral receptors and the cortical areas. There is cumulative evidence showing that thalamus actively gates information flow. An important issue about this role is that thalamus adjusts its response mode according to the sensory information arrived. The corticothalamic feedback signal has been suggested to be essential for such adjustment. In this paper, we pieced together the experimental evidence in a realistic multi-layer network model of the thalamocortical circuit and examined its behavior in response to sinusoidal inputs. The results reproduced the burst/tonic responsive modes and feedback signal’s role in mode transition.
Holographic Video Conferencing for Fostering Communication and Participation: Pre-Conceptualization of Focus Group of Female Learners in Arab Open University (KSA)

Educational institutes are quick to take benefits of technological facilities through incorporating ICT into education, particularly for female students in Saudi education system due to the imposed religious barriers, which sequentially has produced innovative models of education such as, distance learning and blended learning. Deriving from this, holographic video conference (HVC) is considered to be a new tool for better achievement with respect to communication and participation of female students at Arab Open University in Saudi Arabia. This phenomenon makes it progressively important to understand factors impacting it. The study will use design science research (DSR) as a research paradigm that will create and evaluate information technology (IT) artifacts proposed in this research to explain recognized female students’ problems. DSR model includes five phases which are: awareness of problem, suggestion, development, evaluation and conclusion. The proposed research method will be used to determine the perceptions of female learners towards HVC. Using this technique, the effectiveness of HVC in regards to participation and communication of female learners with the male instructors will be determined.

*These authors contributed equally to this work Purpose: In the management of breast-conserving radiotherapy, computed tomography (CT) simulation is now commonly used to identify tumor bed while has difficulties defining precisely. We aimed to evaluate the impact of magnetic resonance (MR) and CT simulation on defining the postoperative tumor bed for breast-conserving radiotherapy in patients without the aid of surgical clips. Methods: From August 2018 to March 2019, twenty patients with T1-2N0M0 breast cancer at our institution were enrolled. All the patients underwent breast-conserving surgery without implantation of surgical clips and were prepared to receive radiotherapy. CT and MR images were acquired on the same day for each patient. Three radiation oncologists independently assigned cavity visualization score (CVS) and delineated the tumor bed based on first the CT then the MR images. Interobserver variability was assessed by volumes, generalized conformity index (CIgen) and the distance between the centers of mass (dCOM). Differences in mean values for parameters were tested by paired t-test or one-way analysis of variance, as appropriate. Results: First, the mean volumes of tumor bed derived from MR were 22%, 27% and 21% smaller than those based on CT images for each observer. In addition, the mean CIgen was significantly superior, and dCOM was smaller for MR than for CT images (CIgen: 0.59 vs 0.52, P= 0.008; dCOM: 1.30 cm vs 1.39 cm, P= 0.095). Moreover, the mean CVS was 3.23 ±1.34 and 2.43±0.92 for MR and CT images, respectively (P= 0.035). Last, a positive association was observed between the CVS and CIgen for both modalities (P< 0.01). Conclusion: Compared to CT, MR can improve the visualization of changes in the postoperative tumor bed. In addition, MR can yield a more precise definition of the tumor bed and improve the consistency of tumor bed contouring in patients without surgical clips.

ON THE INVARIANCE PRINCIPLE AND FUNCTIONAL LAW OF ITERATED LOGARITHM FOR NONERGODIC PROCESSES

: Recently, nonergodic versions of several limit theorems for strictly stationary processes were given ([6], [7], [8]). The proofs were based on the fact that important properties of the stationary process which hold with respect to an invariant measure $\mu$ , are preserved with respect to its ergodic components. Using the same technique we shall prove two nonergodic ver. sions of Heyde’s functional CLT and log log law here.
A Review on the Change of Telecommunication Market in Perspective of Customer

This review examines the rapid growth of qualitative and quantitative of telecommunication industry for past couple of years from customer’s viewpoint. Most of the telecommunication products were positioned in the market by the businesses and government’s support, but the entity of telecommunication products were never interpreted from the user’s viewpoint. Even though, various kinds of telecommunication services have been actively discussed by businesses, government, and IT professionals, it has not been sufficiently discussed by the marketing academia where they need to focus a lot on customer’s utility. For the purpose of providing an insight of the telecommunication service marketing strategy, this study looked over old and new directions of growth, failure and evolution of services by focusing on two main pillar of communication business, which is high-speed internet and mobile phone service. Additionally, the research explains and mentions the limit and trend of the telecommunication service marketing, and the future research task that needs to be solved
Lip Reading of Digits Using Different Classifiers

— This paper describes a method for lip reading of decimal digits. The term lip reading refers to recognizing the spoken words using visual speech information such as lip movements. The visual speech video of the different person is given as input to the face detection module for detecting the face region. The region of the mouth is determined relative to the face region. The mouth images are used for feature extraction. The features are extracted using discrete wavelet transform (DWT). dB-2 & dB-4 wavelets are used for our application. We performed experiment using CAUVE database on 5 persons each uttering each decimal digit 5 times. After feature extraction we get total 250 vectors. Then, these features vector are applied separately as inputs to the Back Propagation Neural Network (ANN) & Support Vector Machine (SVM) for recognizing the visual speech. These classifiers are readily available in WEKA open source software package.

and moisture content 14 and 22%. The influence of participation of exact fiber components and mixture’s moisture on extrudates chemical changes with special compliance of non-starch polysaccharides was tested. An increase in the fiber components share in the mixture increased the content of dietary fibre and protein in extrudates. The extrusion process had destructive influence on non-starch polysaccharides. However the extrusion cooking process resulted in the decrease in the content of dietary fibre (TDF) and its insoluble fraction (IDF) as well as caused an increase in the content on the soluble fraction of fiber (SDF). These changes depended on the composition of the mixture subjected to the extrusion cooking process and moisture content. Also a slight decrease in the protein content in the extrudates compared to the raw materials was observed.
Reproducibility Study: On Heavy-User Bias in A/B Testing Examination of Three Different Papers in Respect to Reproducibility and Reproduction of Selected One

There are many challenges in reproducing experiments in computational sciences. Often the code or the data used are not openly available. Sometimes seemingly smaller factors are not reported on, like operating machines, versions of programming languages and packages, hyper parameters and even random seeds used. In this report, within the scope of the final project of the course "Experiment Design for Data Science" at TU Wien in the fall se-mester 2020/21, we examined three papers of our choice regarding their reproducibility and tried to reproduce one of them.
Rational design of high-quality 2D/3D perovskite heterostructure crystals for record-performance polarization-sensitive photodetection

Polarization-sensitive photodetection is central to optics applications and has been successfully demonstrated in photodetectors of two-dimensional (2D) materials, such as layered hybrid perovskites; however, achieving high polarization sensitivity in such a photodetector remains extremely challenging. Here, for the first time, we demonstrate a high-performance polarization-sensitive photodetector using single-crystalline 2D/3D perovskite heterostructure, namely, (4-AMP)(MA) 4-(aminomethyl)piperidinium), which exhibits ultrahigh polarization sensitivity up to 17.6 under self-driven mode. To our knowledge, such a high polarization selectivity has surpassed all of the reported perovskite-based devices; and is comparable to, or even better than, the traditional inorganic heterostructure-based photodetectors. Further studies reveal that the built-in electric field formed at the junction can spatially separate the photogenerated electrons and holes, reducing their recombination rate and thus enhancing the performance for polarization-sensitive photodetection. This work provides a new source of polarization-sensitive materials and insights into designing novel optoelectronic devices. demonstration that construction of 2D/3D perovskite heterostructure can play a significant role in performance enhancement in polarization-sensitive photodetection. We believe that this work will shed light on designing novel optoelectronic devices beyond conventional materials and approaches.
Dwork's congruences for the constant terms of powers of a Laurent polynomial

We prove that the constant terms of powers of a Laurent polynomial satisfy certain congruences modulo prime powers. As a corollary, the generating series of these numbers considered as a function of a p-adic variable satisfies a non-trivial analytic continuation property, similar to what B. Dwork showed for a class of hypergeometric series.
TC48: A low-cost 48(cid:3027)V integrated drive for mild hybrid electric vehicles

: The TC48 drive is a low-cost, low-voltage integrated motor-drive solution suitable for mild hybrid electric vehicles, off- highway traction, and any application where a compact, highly torque-dense machine is required. Low-voltage solutions for electric vehicles are attractive to manufacturers due to lower insulation requirements, and hence lower cost. The package is based on a six-phase switched reluctance machine, which uses a novel stator topology and unique winding design to achieve high torque density. The power electronics converter hardware is integrated into the motor housing, giving a physically, electrically, and thermally optimised solution. The complete package has been designed to be suitable for manufacturing in high volumes. This study describes the electromagnetic design of the motor, the mechanical innovations used to physically realise this design, and the cooling system which makes the high power density possible. The integration of the power electronics and their control is also discussed. The project is the result of collaboration between Newcastle and Loughbosrough Universities, RDM Ltd., Productiv, Infineon, Tata Steel, and Libralato.
Descriptive Analysis of Somatic Cell Count Using Statistical Tools

Somatic cell count (SCC) can be used as an indicator of subclinical mastitis and its analysis in relation with the milk composition can provide useful information on the existence of some correlations or patterns. Based on milk production data recorded during 5 years (2012-2015, 2017) at the Research and Development Station for Bovine Arad we conducted a statistical analysis aiming to identify correlations between SCC and milk characteristics (protein and fat content, lactose, non-fat solids, milk quantity, pH, casein) and to find potential profiles of SCC evolution. The correlation analysis was based on 226 lactating cows for which at least 20 measurements were available. Both classical correlation coefficient (i.e. Pearson) and correlation coefficient for repeated measurements (i.e. Bland-Altman) have been computed. In both cases, a moderate negative correlation between SCC and the lactose level has been identified while no significant correlation between SCC and the other milk characteristics has been detected. However, a more accurate description of the relation between SCC and lactose was obtained using a linear mixed model. Aiming to analyse SCC profiles, an additional attribute has been added to the data based on the following encoding rule: the attribute has value 0 if SCC is smaller than 2x10 5 cells/ml, 1 if it is larger than 2x10 5 cells/mL and 2 if the value is missing. In this way, data vectors containing 13 values per year have been constructed for 175 cows and a dissimilarity matrix has been constructed as a first step for cluster analysis. Overall, the results have shown that lactose and SCC were negatively correlated.
invited review Noninvasive measurement of hydrogen and potassium ion ﬂux from single cells and epithelial structures

Smith, P. J. S. , and J. Trimarchi. Noninvasive measurement of hydrogen and potassium ion ﬂux from single cells and epithelial structures. Am J Physiol Cell Physiol 280: C1–C11, 2001. —This review introduces new developments in a technique for measuring the movement of ions across the plasma membrane. With the use of a self- referencing ion-selective (Seris) probe, transport mechanisms can be studied on a variety of preparations ranging from tissues to single cells. In this paper we illustrate this versatility with examples from the vas deferens and inner ear epithelium to large and small single cells repre- sented by mouse single-cell embryos and rat microglia. Potassium and hydrogen ion ﬂuxes are studied and pharmacological manipulation of the signals are reported. The strengths of the self-referencing technique are reviewed with regard to biological applications, and the expansion of self-referencing probes to include electrochemical and enzyme-based sensors is discussed.
Insights into Anatomical Basis Prescribing Ventilation-Perfusion Distribution in Lung Periphery

Some crucial problems regarding structural (anatomical) basis on functional parameters describing gas exchange in lung periphery have remained unsolved. Although many definitions for anatomical gas exchange unit (i.e., acinus) have been proposed, there are no authentic study for certifying that anatomically- defined acinus indeed acts as functional gas exchange unit, as well. Among different acini reported so far, we selected acinus of Haefeli-Bleuer (HB acinus) as the most reliable organization. This is simply because microstructures of HB acinus were precisely examined by aid of scanning electron microscopy in addition to light microscopy. Therefore, we first coped with the issue of whether anatomically-defined HB acinus would meet the definition of functional gas exchange unit, i.e., the gas concentration is constant in any region of this organization. We were confronted with an interesting phenomenon that spatial PO 2 gradient exists along the axial direction of HB acinus over inspiration, but it almost disappears over expiration, leading to the conclusion that anatomically-defined HB acinus indeed acts as functional gas exchange unit on expiration but not on inspiration. This fact certainly indicates that functional gas exchange parameters measured on expiration, such as V A /Q heterogeneity investigated from Multiple Inert Gas Elimination Technique (MIGET), can be considered to reflect microstructural abnormalities at the level of HB acinus. Subsequently, we tried to validate the issue of whether V A /Q heterogeneities estimated from MIGET would well explain the structural abnormalities in patients with pathologically-and/or radiologically-confirmed lung diseases.
