EFFECTIVE ESTIMATES ON THE VERY AMPLENESS OF THE CANONICAL LINE BUNDLE OF LOCALLY HERMITIAN SYMMETRIC SPACES

We study the problem about the very ampleness of the canonical line bundle of compact locally Hermitian symmetric manifolds of non-compact type. In particular, we show that any suciently large unramied covering of such manifolds has very ample canonical line bundle, and give estimates on the size of the covering manifold, which is itself a locally Hermitian symmetric manifold, in terms of geometric data such as injectivity radius or degree of coverings. Let L be an ample line bundle on an algebraic manifold M. From Kodaira's Embedding Theorem, we know that mL is very ample if m is suciently large so that the sections of mL give rise to an embedding of M into some projective space. A natural question is on the estimates of such m so that mL is very ample. In particular, one may ask the same question for the canonical line bundle of a manifold with negative rst Chern class, or of general type. Of particular interest among such manifolds is the class of locally Hermitian symmetric spaces. The main purpose of this article is to show that for compact locally Hermitian symmetric manifolds of non-compact type, K is very ample if the injectivity radius of the manifold is greater than some eective constant which can be estimated in terms of some geometric data. Eective estimates for mK = K +( m 1)K with m 2 in terms of injectivity radius have been obtained in (HT) and (Y2). The diculty in the case of m =1c an be seen from the fact that in constructing holomorphic sections from the Bochner- Kodaira technique, one always needK +L for some extra positivity fromL . I n (Y2), it is shown that for a tower of coverings of compact Hermitian locally symmetric manifolds Mi, KMi becomes very ample when i approaches to1. To compensate for the extra positivity required for the Bochner-Kodaira technique, we prove our result by showing that the limit of the Bergman kernel on Mi approaches the corresponding one on the universal covering. However, the limiting process makes the whole approach highly non-eective and requires an innite sequence of normal coverings of the original manifold. The main purpose of this article is to show the very ampleness of KM for any unramied covering M of Mo with injectivity radius or degree of the coverings greater than some eectively estimable constant. For this purpose, an alternate approach using heat kernel estimates combined with Atiyah's
Primary hepatic epithelioid angiomyolipoma: A malignant potential tumor which should be recognized.

AIM To improve the clinical diagnosis and recognition of hepatic epithelioid angiomyolipoma (HEAML). METHODS Four cases of primary HEAML were confirmed based on the pathology archive system in our hospital from January 2009 to November 2015. The general state, clinical symptoms, imaging manifestations, histological results and immunohistochemistry of these patients were retrospectively reviewed and analyzed. Studies of HEAML published in the last 15 years were collected from PubMed and MEDLINE to summarize the clinical symptoms, imaging characteristics, pathological features and management of HEAML. RESULTS Four cases of primary HEAML were retrieved from our archives. These included three female patients and one male patient, with a mean age of 41.8 ± 11.5 years (ranging from 31 to 56 years). The mean tumor size was 7.3 ± 5.5 cm (ranging from 3.0 to 15 cm). In the contrast-enhanced imaging, the tumor was obviously enhanced in the arterial phase, but enhanced continuously or exhibited a slow-density masse during the venous and delayed phases. Histologically, the tumors mainly consisted of epithelioid cells that comprised approximately 95% of the total neoplastic mass. Although no metastases occurred in our patients, pathological studies revealed necrosis, mitotic figures and liver invasion in two patients, which indicates aggressive behavior. Immunohistochemical staining revealed that human melanoma black 45 (HMB-45) and Melan-A were positive in 4 cases. We only identified 81 cases with primary HEAML, including our present patients, from 26 articles available from PubMed and MEDLINE. The majority of the papers were published as case reports. Only 5 (5/75, 6%) cases were associated with tuberous sclerosis complex (TSC). More than half (35/66) were discovered incidentally upon physical examination. Approximately 65% (22/34) of the patients were misdiagnosed with HCC or other tumors before surgery. Approximately 10% (8/81) of the patients with HEAML had recurrence or metastasis after surgery, which was a very high and alarming rate. CONCLUSION HEAML is a very rare primary hepatic tumor that is often misdiagnosed before surgery. Patients should be followed closely after surgery because of its malignant potential.
THE VIRTUAL BOEHM FLUTE — A WEB SERVICE THAT PREDICTS MULTIPHONICS, MICROTONES AND ALTERNATIVE FINGERINGS

We report a web service for flute players, 'The Virtual Boehm Flute', that provides alternative fingerings which may be easier to play, less awkward to finger and/or more in tune for different circumstances. It also provides possible fingerings for multiphonics (chords). It uses an expert system that predicts the playability of notes from features in the input impedance spectra, based on the playability of 957 impedance minima as determined by an expert flutist. Used in conjunction with a theoretical model, developed from detailed experimental measurements, it can predict the acoustic impedance spectrum for 39,744 different acoustic configurations of the flute. The resulting database provides, via a musician-friendly interface, the predicted possible notes and multiphonics for any selected fingering, and all the possible fingerings predicted to play a desired note or multiphonic. The service is at http://www.phys.unsw.edu. au/music/flute
Deep Hierarchical Encoder–Decoder Network for Image Captioning

Encoder–decoder models have been widely used in image captioning, and most of them are designed via single long short term memory (LSTM). The capacity of single-layer network, whose encoder and decoder are integrated together, is limited for such a complex task of image captioning. Moreover, how to effectively increase the “vertical depth” of encoder–decoder remains to be solved. To deal with these problems, a novel deep hierarchical encoder–decoder network is proposed for image captioning, where a deep hierarchical structure is explored to separate the functions of encoder and decoder. This model is capable of efficiently exerting the representation capacity of deep networks to fuse high level semantics of vision and language in generating captions. Specifically, visual representations in top levels of abstraction are simultaneously considered, and each of these levels is associated to one LSTM. The bottom-most LSTM is applied as the encoder of textual inputs. The application of the middle layer in encoder–decoder is to enhance the decoding ability of top-most LSTM. Furthermore, depending on the introduction of semantic enhancement module of image feature and distribution combine module of text feature, variants of architectures of our model are constructed to explore the impacts and mutual interactions among the visual representation, textual representations, and the output of the middle LSTM layer. Particularly, the framework is training under a reinforcement learning method to address the exposure bias problem between the training and the testing by the policy gradient optimization. Qualitative analyses indicate the process that our model “translates” image to sentence and further visualization presents the evolution of the hidden states from different hierarchical LSTMs over time. Extensive experiments demonstrate that our model outperforms current state-of-the-art models on three benchmark datasets: Flickr8K, Flickr30K, and MSCOCO. On both image captioning and retrieval tasks, our method achieves the best results. On MSCOCO captioning Leaderboard, our method also achieves superior performance.
Recreational and small-scale fisheries may pose a threat to vulnerable species in coastal and offshore waters of the western Mediterranean

This study evaluates the fishing pressure exerted by the most common recreational and professional, small-scale fishing practices on vulnerable target and bycatch species in coastal and offshore waters of the western Mediterranean. By combining multiple data sources, we assembled a unique dataset on catches at multiple sites in these areas by recreational (RF) and small-scale fisheries (SSF), covering the period from 1997 to 2015. Furthermore, a framework with which to identify the vulnerable species among all the species caught is provided; it is based on the IUCN Red List, international conventions for the protection of flora and fauna, the Habitats Directive and the intrinsic vulnerability index of marine fish. Overall, about a quarter of exploited species targeted by SSF and RF in coastal waters were vulnerable, making up nearly 50% of the total SSF catch and nearly 20% of the total recreational catch. In offshore waters, 100% of the RF and SSF catch was made up of vulnerable species. Among the species caught as bycatch in both areas by SSF and RF, there was a total of 27 vulnerable vertebrate species, which included birds, cetaceans, elasmobranchs and sea turtles. Our results highlight the need to differentiate between different fishing methods or gears when studying the fishing impacts on vulnerable species. The results also indicate that, although RF and SSF are often considered to have a relatively low ecological impact, a range of different fishing methods are affecting vulnerable species in coastal or offshore waters in the western Mediterranean Sea, be they targeted or taken unintentionally as bycatch.
Long-Term Results of Elective Stenting for Severe Carotid Artery Stenosis in Taiwan

Stenting for severe carotid stenosis has been proposed as an alternative for patients with high surgical risk for endarterectomy, but its effectiveness and safety has never been evaluated in large case series in a pure Asian population. One hundred and eighteen ethnic Chinese patients (mean age 72.8 years) with 129 severely narrowed carotid arteries were stented electively using self-expanding stents. The mean pre-treatment diameter stenosis was 85% and final residual diameter stenosis 14%. The peri-procedural stroke and death rate was 4.2%. One (0.8%) late ischemic stroke and 2 (1.7%) deaths occurred during a mean follow-up of 16.3 months, and the restenosis rate was 3.1%. Carotid stenting, therefore, can be done safely and effectively in Chinese patients.
Does Infliximab Prevent Colectomy in Acute and Chronic Active Ulcerative Colitis?

Objectives: The aim of the study was to evaluate clinical response, use of colectomy, and adverse events related to infliximab (IFX) treatment in acute and chronic active ulcerative colitis (UC) in children. Methods: Children from 3 centers, who had received IFX for UC, were identified, and patient charts were reviewed retrospectively. Data concerning symptoms, biochemistry, concomitant medical treatment, colectomy, and adverse events were registered. Results: A total of 45 patients with UC (median age at diagnosis 12 years, interquartile range 10–14) were included, and studied for a median of 15 months (interquartile range 4.5–29) after first IFX infusion. The cumulative 1- and 2-year risks of colectomy were 21% and 26%, respectively. The cumulative 1- and 2-year risks of receiving a new course of systemic corticosteroids were 32% and 48%, respectively. Twenty-one patients (46%) experienced adverse events. Most common were mild infusion reactions, but 3 (7%) had serious adverse events. Conclusions: IFX was efficient in preventing colectomy in children with UC. The risk of receiving systemic corticosteroids was lower than that reported in other studies. Most adverse events were mild to moderate and self-limiting.
What matters more in patient care? Giving doctors shorter hours of work or a good night’s sleep?

It is important that education on stroke is provided in ways that people can really understand Getting people to hospital quickly for specialist care after a stroke saves lives and reduces disability.1 However, for many people, the most appropriate care is delayed and, in some cases, may not happen at all. Other than the ongoing lack of specialist stroke services, what is it that impedes access to best services for patients who have a stroke? Huge efforts have been made to highlight the seriousness of stroke and the importance of getting swift medical attention. However, the long lasting effects of education and screening campaigns are debatable,2–4 providing a reminder (if one were needed) of the complexity of health promotion for behaviour change. Key questions to face are whether the level of knowledge about stroke is good enough, and whether that knowledge leads to appropriate action when people experience a stroke. A number of recent studies have explored the quality of the public’s knowledge about stroke and many make depressing reading.2,3 The recent study by Carroll et al 5 (summarised in the “Echo” which appears on page 168 of this issue of QSHC ) presents contrasting findings about the level …
Media Influences on Body Size Estimation in Anorexia and Bulimia

Anorexic end bulimic women overestimate their body sizes substantially more than comparison women, but little is known about the factors that influence this overestimation. This study examined the influence of media portrayal of idealised female bodies in women's fashion magazines. Comparison women were not affected by the nature of the photographs that they saw, but eating-disordered women were - they overestimated more when they had seen the pictures of women than when they saw photographs of neutral objects.
Promoting early achievement in low-income preschoolers in the United States with educational apps

ABSTRACT The present study examined the potential of educational apps for mobile devices as a home-based learning tool to promote preliteracy and emergent math development among preschool-aged children. A randomized controlled trial was conducted with 22 preschoolers from low-income families and their primary caregivers. Children demonstrated substantively significant gains in preliteracy and emergent math skills after 3 months of educational app use at home, compared with a control group who used wholesome entertainment apps over the same period. Parent-rated academic interest also significantly increased for the experimental group compared to the control group. The educational apps were well-received and used as directed. Apps were most often used with a parent or sibling. Given the prevalence of mobile devices – even in the lowest income communities – and the low cost of apps, educational apps may be a promising avenue of intervention to address early achievement gaps.
Complications of negative pressure wound therapy: A mini review

Negative pressure wound therapy, with its wide indications and narrow contraindications, has been widely used for various complicated wounds. Despite its excellent properties in promoting wound healing, there are sporadic but increasing reports on the complications. These complications included bleeding, infection, pain, rupture of the heart, and death in the short term. When used for the long term, the therapy may decrease life quality, increase anxiety, and lead to malnutrition. In this review, we briefly summarize the complications of negative pressure wound therapy.
Effect of Microalgae Incorporation on Quality Characteristics and Functional and Antioxidant Capacities of Ready-to-Eat Fish Burgers Made from Common Carp (Cyprinus carpio)

Microalgae have been used as natural ingredients to produce functional and nutritional food products. The impact of the addition of Chlorella minutissima, Isochrysis galbana, and Picochlorum sp. at concentrations of 0.5, 1, and 1.5% w/v on the texture and sensory attributes of canned burgers were investigated. The results show that carp formulations containing 1% microalgae show significantly better classification performance for many textural and sensory parameters compared to the rest of the formulations. Also, these treatments had higher swelling ability as well as water and oil holding capacities, thanks to the important dietary fiber and polysaccharide contents found in microalgae. Moreover, microalgae-supplemented burgers were characterized as having low a* and b* values, which made the color appear to be pale orange. Additionally, thanks to its richness in pigments and polysaccharides, microalgae considerably ameliorated the antioxidant activities of the new prepared fish burgers. Thus, microalgae could be used as natural and nutritious ingredient to develop new fish-based products.
What determines the role and position of works councils? Models of councils in Polish organizations

Using data from in-depth interviews conducted with chairpersons of works councils, representatives of management and chairpersons of trade unions in 20 Polish organizations, this article explores the importance of different factors influencing the strength of works councils. The findings indicate a decisive role of such factors as management approach and activity of councillors, and a minor role in the case of individual regulations and works council’s age. Moreover, the article identifies three main models of works councils existing in Polish organizations after the amendment of the Act on Informing and Consulting Employees: ‘perfunctory’ councils, ‘constructive’ councils and works councils as a ‘complement to unions’.
The spread of multiply resistant Streptococcus pneumoniae at a day care center in Ohio.

Streptococcus pneumoniae, type 23F, resistant to penicillin (MIC, 2 micrograms/mL) and multiple other antimicrobic agents, was isolated from middle ear fluid of a child with otitis media attending a day care center in Ohio. To determine the extent of spread of this strain, nasopharyngeal culture surveys were done, and 52 carriers were identified among 250 children attending the index day care center. No carriers were found among 121 children at two other day care centers in the same urban area. Use of prophylactic doses of antibiotics (P < .001) and frequent use of antibiotics (P < 0.001) were risk factors for nasopharyngeal carriage. Carriers were more likely to have had frequent otitis media episodes (P < .02) and otitis media not responsive to antimicrobial therapy (P < .001). Strategies to limit the spread of highly resistant pneumococcal strains should include encouraging judicious use of antimicrobic agents and reevaluating indications for prophylactic use of antimicrobic agents.
A method to evaluate the field-shape multipoles induced by coil deformations

A semi-analytical method to evaluate the effect of coil deformations on the field-shape imperfections of the LHC dipole is presented. The deformation induced by the collaring procedure and by the thermal stresses is evaluated numerically with a finite element code. The vector field of mechanical displacements is approximated with truncated Taylor and Fourier series. The fitting function agrees with the numerical data to within less that 10 /spl mu/m. The decomposition in modes of the truncated series permits identification of displacements which are dangerous for the multipolar content and how they could be cured. An application to compare two designs of the LHC dipole is given.
Modeling of carrier mobility against carrier concentration in arsenic-, phosphorus-, and boron-doped silicon

New carrier mobility data for both arsenic- and boron-doped silicon are presented in the high doping range. The data definitely show that the electron mobility in As-doped silicon is significantly lower than in P-doped silicon for carrier concentrations higher than 1019cm-3. By integrating these data with those previously published, empirical relationships able to model the carrier mobility against carrier concentration in the whole experimental range examined to date (about eight decades in concentration) for As-, P-, and B-doped silicon are derived. Different parameters in the expression for the n-type dopants provide differentiation between the electron mobility in As-and in P-doped silicon. Finally, it is shown that these new expressions, once implemented in the SUPREM II process simulator, lead to reduced errors in the simulation of the sheet resistance values.
Comparing the direct normal form method with harmonic balance and the method of multiple scales

Approximate analytical methods have been used extensively for finding approximate solutions to nonlinear ordinary differential equations. In this paper we compare the recently developed direct normal form transformation with two other very well known and long standing methods, harmonic balance and the method of multiple scales. We will show that the direct normal form method combines some of the key advantages of harmonic balance and multiple scales whilst reducing some of the limitations. c 2017 The Authors.

Empirical Absolute Calibration Model for Multiple Pseudo-Invariant Calibration Sites

This work extends an empirical absolute calibration model initially developed for the Libya 4 Pseudo-Invariant Calibration Site (PICS) to five additional Saharan Desert PICS (Egypt 1, Libya 1, Niger 1, Niger 2, and Sudan 1), and demonstrates the efficacy of the resulting models at predicting sensor top-of-atmosphere (TOA) reflectance. It attempts to generate absolute calibration models for these PICS that have an accuracy and precision comparable to or better than the current Libya 4 model, with the intent of providing additional opportunities for sensor calibration. In addition, this work attempts to validate the general applicability of the model to other sites. The method uses Terra Moderate Resolution Imaging Spectroradiometer (MODIS) as the reference radiometer and Earth Observing-1 (EO-1) Hyperion image data to provide a representative hyperspectral reflectance profile of the PICS. Data from a region of interest (ROI) in an “optimal region” of 3% temporal, spatial, and spectral stability within the PICS are used for developing the model. The developed models were used to simulate observations of the Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+), Landsat 8 (L8) Operational Land Imager (OLI), Sentinel 2A (S2A) MultiSpectral Instrument (MSI) and Sentinel 2B (S2B) MultiSpectral Instrument (MSI) from their respective launch date through 2018. The models developed for the Egypt 1, Libya 1 and Sudan 1 PICS have an estimated accuracy of approximately 3% and precision of approximately 2% for the sensors used in the study, comparable to the current Libya 4 model. The models developed for the Niger 1 and Niger 2 sites are significantly less accurate with similar precision.
