Model-based Solid Texture Synthesis for Anatomic Volume Illustration

Medical illustrations can make powerful use of texture synthesis to convey information about anatomic structures in an attractive, effective and understandable way. Current visualization methods are not capable of conveying detailed information about the orientation, internal structure, and other local properties of the anatomical objects for a particular patient because imaging modalities such as CT or MRI do not capture this information. In this paper, a new anatomical rendering method that utilizes model-based synthesis of 3D textures is proposed in order to distinguish and illustrate different structures inside the model. The goal of our volume illustration approach is to visualize structural information by considering directions and layers in synthesizing high-quality, high-resolution solid textures. Our method uses medial coordinates of 3D models and 2D exemplar textures to generate solid textures that change progressively in orientation and material according to the local orientation and transition information implicit in the anatomic region. Discrete medial 3D anatomical models ("m-reps") provide the orientation field and texture variation maps inside image regions. In our paper, we demonstrate the robustness of our method with a variety of textures applied to different anatomical structures, such as muscles, and mandible.
Dynamic Selection of Physical Channels for Adaptive Improvement of Link Quality Using an Agile Aperture Antenna

This paper describes integration of a software defined antenna (SDA) and a software defined radio (SDR) to enable dynamic and automatic selection of physical propagation channels. The SDA, an agile aperture antenna (A3), provides monolithic microdiversity, i.e. multiple antenna states within a single structure and within a space having maximum dimension of approximately one wavelength. In this way physical channel selection occurs outside, and therefore augmenting, the front-end electronics. The independent controllable parameters for channel access include: frequency, polarization (full Poincaré sphere), and pattern (in two dimensions). Several different tests were conducted to maximize a quality figure of merit calculated by the radio. Both library-based and evolutionary search techniques were used, resulting in short term channel improvements on the order of 10 dB, and long term fully optimized improvements on the order of 20 dB.
Relationship between ever reporting depressive symptoms and all-cause mortality in a cohort of HIV-infected adults in routine care

Objective: The aim of this study was to assess whether ever reporting depressive symptoms affects mortality in the modern HIV treatment era. Design: AcohortstudyofHIV-infectedadultsinroutineclinicalcareatsevensitesintheUSA. Methods: We examined the effect of ever reporting depressive symptoms on all-cause mortality using data from the Centers for AIDS Research Network of Integrated Clinical Systems cohort. We included individuals with at least one depression measure between 2005 and 2014. Depressive symptoms were measured with the Patient Health Ques-tionnaire (PHQ)-9. We used weighted Kaplan–Meier curves and marginal structural Cox models with inverse probability weights to estimate the effect of ever reporting depressive symptoms (PHQ-9 (cid:2) 10) on all-cause mortality. Results: A total of 10 895 individuals were included. Participants were followed for a median of 3.1 years (35 621 total person-years). There were 491 (4.5%) deaths during the follow-up period (crude incidence rate 13.8/1000 person-years). At baseline, 28% of the population reported depressive symptoms. In the weighted analysis, there was no evidence that ever reporting depressive symptoms increased the hazard of all-cause mortality (hazard ratio 0.82, 95% conﬁdence interval 0.55–1.24). Conclusion: In a large cohort of HIV-infected adults in care in the modern treatment era, we observed no evidence that ever reporting depressive symptoms increased the likelihood of all-cause mortality, controlling for a range of time-varying factors. Antiretroviral therapy that is increasingly robust to moderate adherence and improved access to depression treatment may help to explain changes in the relationship between depressive symptoms and mortality in the modern treatment era.
A Study on Chinese Quantitative Stylistic Features and Relation Among Different Styles Based on Text Clustering*

Abstract The corpora for this study are from News Co-broadcasting, Daily Conversations and Behind the headlines with Wentao, each of which represents the formal written style, the colloquial style and the conversational style respectively. Sentence length, word length, part of speech (POS) and sentence-initial word POS are selected from the pre-processed corpora as features to generate text vectors and then clustered with PAM (partition around medoids) and Ward algorithms. The clustering results show: (1) It is reasonable to select sentence length, word length, POS and sentence-initial word POS as Chinese quantitative stylistic features. (2) Style is a polarized continuum, as the formal written style and the colloquial style display bipolar distributions while the conversational style lies in between and is near the pole of the colloquial style.
Approximation Algorithms for Energy, Reliability, and Makespan Optimization Problems

We consider the problem of scheduling an application on a parallel computational platform. The application is a particular task graph, either a linear chain of tasks, or a set of independent tasks. The platform is made of identical processors, whose speed can be dynamically modified. It is also subject to failures: if a processor is slowed down to decrease the energy consumption, it has a higher chance to fail. Therefore, the scheduling problem requires us to re-execute or replicate tasks (i.e., execute twice the same task, either on the same processor, or on two distinct processors), in order to increase the reliability. It is a tri-criteria problem: the goal is to minimize the energy consumption, while enforcing a bound on the total execution time (the makespan), and a constraint on the reliability of each task. Our main contribution is to propose approximation algorithms for linear chains of tasks and independent tasks. For linear chains, we design a fully polynomial-time approximation scheme. However, we show that there exists no constant factor approximation algorithm for independent tasks, unless P=NP, and we propose in this case an approximation algorithm with a relaxation on the makespan constraint.
Metabolomics and its application for non-invasive embryo assessment in IVF

Morphology and cleavage rate remain the mainstay of embryo assessment. However, a number of additional technologies for this application are under investigation. These include the measurement of glucose, lactate, pyruvate or amino acid levels in the embryo culture media, assessment of oxygen consumption by the embryo, genomic and proteomic profiling, and most recently, analytical examination of the embryonic metabolome. As the number of assisted reproduction cycles increases worldwide, improvements in the ability to quickly and non-invasively identify the best embryos for transfer remain a critical goal for reproductive medicine. Recent studies suggest that metabolomic profiling of embryo culture media using optical and non-optical spectroscopies may provide a useful adjunct to the current embryo assessment strategies and provide insight into the phenotype of embryos with increasing reproductive potential.
how to study determinants related to medication adherence in newly diagnosed polyarthritis patients for the development of a prediction instrument

methods. The consecutive steps that we conducted for the development of a tool for the prediction of adherence in our study sample of early arthritis patients are described. Discussion: Although we used a thorough procedure, there are still some pitfalls to take into account, such as the choice of theoretical framework. A strength of this study is that we use multiple adherence measurement methods and that we also take clinical outcomes into account.
Cells and Tissues: A Three-Dimensional Approach by Modern Techniques in Microscopy

Cells and Tissues: A Three-Dimensional Approach by Modern Techniques in Microscopy is a compilation of individual efforts presented at the Eighth International Symposium on Morphological Sciences held in Rome, Italy, July 10-15, 1988. The book, volume 295 in a series entitled Progress in Clinical and Biological Research, is an impressive collection of electron micrographs of a multitude of tissue cell types. Dedicated to presenting the ultra-morphology of cells with an emphasis on threedimensional structure, most of the illustrations displayed and techniques discussed focus on scanning electron microscopy (SEM). The first major section of Cells and Tissues, called "The Cell," considers some of the latest methods being employed in electron microscopy. Techniques discussed include a freeze-fracture preparation to study interphase chromatin structure, a new "fractureflip" method to study the topochemistry of cell surfaces, and color laser for analysis of chromosomal structure. The volume is organized into sections consisting of six to 19 articles, placed under one of the following broad system headings: Connective and Muscle Tissues (eight articles), Respiratory and Urinary Systems (eight articles), Glands and Development ( 1 articles), Digestive Tract (six articles), Neuroendocrine, Cardiocirculatory, and Immune Systems (19 articles), and Eye and Ear (seven articles). The last section of the volume considers the future of microscopy with interesting topics such as the use of colored SEM pictures in teaching anatomy, the use of SEM in clinics, and that of various techniques on the horizon. The strength of this book lies in its high-quality original illustrations. Some of the more intriguing photomicrographs are found in the gastrointestinal section, featuring SEMs of tongue stereo architecture, corrosion casts of gastric microcirculation, and ganglion plexuses in the small intestine. Indeed, Cells and Tissues captures the magic of scanning electron microscopy by bringing the reader close enough to subcellular structures so that he or she can almost "feel" their dimensionality. Unfortunately, the text of Cells and Tissues consists of separate articles that do not flow freely together. The differing typefaces used in each article and the obvious corrections in one give the book an unprofessional appearance. Moreover, a few articles include run-on sentences, while others are written in a somewhat choppy style. Perhaps some of these problems are to be expected when a single English text is compiled from the works of two hundred authors around the world. As far as presenting an abundance of information on the subject of cellular ultrastructure, Cells and Tissues is perhaps the most comprehensive text available; it should prove an invaluable source for researchers and lecturers on cell biology and histology. If one believes that the old adage "One picture is worth a thousand words" (or even a couple of hundred) is true, then Cells and Tissues may very well be worth its $165.00 price.
Haematological Evaluations of the Antimalarial Activity of Bridelia ferruginea Benth Bark

We investigated the antimalarial activity of the methanolic extract of Bridelia ferruginea benth bark at 400 mg/kg body weights in mice ( Mus musculus ) infected with chloroquine-sensitive Plasmodium berghei using the rane test. There was decreased in packed cell volume, RBC and Hb in infected groups from day zero to 14 with a corresponding increase in RBC of the uninfected -extract treated group ( p <0.05). The infected – untreated showed continual decreased from day zero to 14 ( p <0.05) compared to the infected – treated groups and the uninfected – untreated (control) group. However, decreased in MCHC was recorded by day 14 for the infected – untreated animals. WBC and lymphocytes indices revealed that there was no significant difference in all the groups by day zero, however by day 14, there was significant increased in the WBC and lymphocytes for infected – treated groups compared to all other groups ( p <0.05). In the platelets count, by day 14 there was significant decreased in the infected – untreated group compared to others ( p <0.05). Also, there was no significant difference in the neutrophils for the infected – extract treated, infected – chloroquine treated, control, and uninfected – extract treated groups ( p <0.05). The haematological indices further substantiates the promising antimalarial activity of the bark extract.
Update on ventilator-associated pneumonia

Ventilator-associated pneumonia (VAP) is the most frequent life-threatening nosocomial infection in intensive care units. The diagnostic is difficult because radiological and clinical signs are inaccurate and could be associated with various respiratory diseases. The concept of infection-related ventilator-associated complication has been proposed as a surrogate of VAP to be used as a benchmark indicator of quality of care. Indeed, bundles of prevention measures are effective in decreasing the VAP rate. In case of VAP suspicion, respiratory secretions must be collected for bacteriological secretions before any new antimicrobials. Quantitative distal bacteriological exams may be preferable for a more reliable diagnosis and therefore a more appropriate use antimicrobials. To improve the prognosis, the treatment should be adequate as soon as possible but should avoid unnecessary broad-spectrum antimicrobials to limit antibiotic selection pressure. For empiric treatments, the selection of antimicrobials should consider the local prevalence of microorganisms along with their associated susceptibility profiles. Critically ill patients require high dosages of antimicrobials and more specifically continuous or prolonged infusions for beta-lactams. After patient stabilization, antimicrobials should be maintained for 7–8 days. The evaluation of VAP treatment based on 28-day mortality is being challenged by regulatory agencies, which are working on alternative surrogate endpoints and on trial design optimization.
An Improved Method for Purification of Marine Cyanobacteria Isolated from the Gulf of Thailand

Thirty five marine cyanobacteria isolates obtained from water samples collected from the Gulf of Thailand of the Chumpon and Chonburi provinces. They were purified by homogenizing, washing, lysozyme, antibiotics and dilution. Successful purifications were checked by morphological characterization (plate culture and scanning electron microscope) and molecular methods (Multiplex randomly amplified polymorphic DNA and 16S rRNA gene). This study presents the results of axenic cyanobacteria were obtained on ASNIII agar plates and scanning electron microscopy. The DNA fingerprints of all axenic marine cyanobacteria were divided into eight clusters and identified using 16S rRNA gene sequence correlatively close to Geitlerinema sp. , Leptolyngbya valdenosa , Leptolyngbya sp. , Synechococcus sp. , Pseudanabaena limnetica ( Oscillatoria limnetica ) and Oscillatoriales cyanobacterium.
Time evolution of an infinite projected entangled pair state An

An inﬁnite projected entangled pair state (iPEPS) is a tensor network ansatz to represent a quantum state on an inﬁnite 2D lattice whose accuracy is controlled by the bond dimension D . Its real, Lindbladian, or imaginary time evolution can be split into small time steps. Every time step generates a new iPEPS with an enlarged bond dimension D (cid:2) > D , which is approximated by an iPEPS with the original D . In P. Czarnik and J. Dziarmaga, Phys. Rev. B 98 , 045110 (2018), an algorithm was introduced to optimize the approximate iPEPS by maximizing directly its ﬁdelity to the one with the enlarged bond dimension D (cid:2) . In this paper, we implement a more efﬁcient optimization employing a local estimator of the ﬁdelity. For imaginary time evolution of a thermal state’s puriﬁcation, we also consider using unitary disentangling gates acting on ancillas to reduce the required D . We test the algorithm simulating Lindbladian evolution and unitary evolution after a sudden quench of transverse ﬁeld h x in the 2D quantum Ising model. Furthermore, we simulate thermal states of this model and estimate the critical temperature with good accuracy: 0 . 1% for h x = 2 . 5 and 0 . 5% for the more challenging case of h x = 2 . 9 close to the quantum critical point at h x = 3 . 04438(2).

U–Pb–Hf isotopes and trace elements of metasomatic zircon delimit the evolution of neoproterozoic Capané ophiolite in the southern Brasiliano Orogen

ABSTRACT The Capané ophiolite is a fragment of oceanic lithosphere obducted into the Ediacaran Porongos fold and thrust belt, southern Brasiliano Orogen. A studied rodingite blackwall contained in serpentinite has metasomatic zircon that displays multiple U–Pb ages from Tonian to Cryogenian (793 ± 0.9, 757 ± 2.1, 715 ± 2.2 Ma). The ages are interpreted as corresponding to multiple alteration events in the mantle. Multiple U–Pb–Hf isotopes and trace element analyses on the same crystals by laser ablation were controlled by backscatered electron images. Hf isotopes indicate zircon origin from a depleted mantle (εHf = +15 to +10.7), and trace elements point to an oceanic origin. The Capané ophiolite thus marks the evolution of the Adamastor ocean during the Tonian and Cryogenian, a significant result for the reconstruction of Rodinia and Gondwana supercontinents.
Human Body Shape Estimation Using a Multi-resolution Manifold Forest

This paper proposes a method for estimating the 3D body shape of a person with robustness to clothing. We formulate the problem as optimization over the manifold of valid depth maps of body shapes learned from synthetic training data. The manifold itself is represented using a novel data structure, a Multi-Resolution Manifold Forest (MRMF), which contains vertical edges between tree nodes as well as horizontal edges between nodes across trees that correspond to overlapping partitions. We show that this data structure allows both efficient localization and navigation on the manifold for on-the-fly building of local linear models (manifold charting). We demonstrate shape estimation of clothed users, showing significant improvement in accuracy over global shape models and models using pre-computed clusters. We further compare the MRMF with alternative manifold charting methods on a public dataset for estimating 3D motion from noisy 2D marker observations, obtaining state-of-the-art results.
Gender Responsive Pedagogy Practices: Secondary School Gender Responsive Pedagogy Practices: Secondary School Science Teachers in Ethiopia Science Teachers in Ethiopia

This paper examines the current status of secondary school science teachers' gender-responsive pedagogy (GRP) practices. Women’s participation in secondary school teaching is a major concern in many regions of the world. The use of instructional strategies that promote gender inclusion and sensitivity in initial teacher training is very important in the development of teachers. In this paper, the use of gender-responsive pedagogy in Ethiopia’s secondary school program is highlighted. Using data from baseline, midterm, and end-line surveys, the paper addresses how tutors and mentors use gender-responsive pedagogy and the changes that have occurred as a result. The study adopted a qualitative approach using lesson observations and interviews to capture data from ten novice teachers and twenty mentors sampled from six secondary schools. The findings presented in this paper reveal that there has been significant improvement in the use of gender-responsive pedagogy by tutors within the core subjects (English, Mathematics, and Science). Both male and female tutors demonstrated increasing use of gender-responsive pedagogy in their teaching. A similar increase has been found in the use of gender-responsive mentoring strategies by mentors. The paper concludes by highlighting the implications of the findings for policy in the use of gender-sensitive pedagogy in Ethiopia’s secondary school program. It also assesses the GRP practicing status of the teachers according to their gender and level of teaching experience. The required data were gathered from teachers, department heads, school principals, and students via interview and focus group discussion (FGD). The qualitative data were organized thematically by taking into account the issues raised in the research questions. By so doing, the findings revealed that science teachers were competent in their classroom organization and interaction and in tackling sexual harassment. On the contrary, they were ineffective in creating gender-sensitive lesson plans and teaching materials, and they also were weak in treating the subject of sexual maturation. The study also found that the teacher’s gender and their level of teaching experience did not affect their GRP practices.
Correlation between Animal and Mathematical Models for Prostate Cancer Progression

This work demonstrates that prostate tumour progression in vivo can be analysed by using solutions of a mathematical model supplemented by initial conditions chosen according to growth rates of cell lines in vitro. The mathematical model is investigated and solved numerically. Its numerical solutions are compared with experimental data from animal models. The numerical results confirm the experimental results with the growth rates in vivo.
Simple Pseudorandom Number Generator with Strengthened Double Encryption (Cilia)

A new cryptographic pseudorandom number generator Cilia is presented. It hashes real random data using an iterative hash function to update its secret state, and it generates pseudorandom numbers using a block cipher. Cilia is a simple algorithm that uses an improved variant of double encryption with additional security to generate pseudorandom numbers, and its performance is similar to double encryption. Futhermore, cryptanalytic attacks are presented.
Implicit Discourse Relation Recognition by Selecting Typical Training Examples

Implicit discourse relation recognition is a challenging task in the natural language processing field, but important to many applications such as question answering, summarizat ion and so on. Previous research used either art ificially created implicit discourse relat ions with connectives removed from explicit relations or annotated implicit relat ions as training data to detect the possible implicit relations, and do not further discern which examples are fit to be training data. This paper is the first time to apply a d ifferent typical/atypical perspective to select the most suitable discourse relation examples as training data. To differentiate typical and atypical examples for each discourse relation, a novel single centroid clustering algorithm is proposed. With this typical/atypical distinction, we aim to recognize those easily identified discourse relations more precisely so as to promote the performance of the implicit relation recognition. The experimental results verify that the proposed new method outperforms the state -of-the-art methods.
