Dynamics of bimeromorphic maps of surfaces

We classify bimeromorphic self-maps f : X [inline-graphic xmlns:xlink="http://www.w3. org/1999/xlink" xlink:href="01i" /] of compact Kahler surfaces X in terms of their actions f *: H 1,1 ( X ) [inline-graphic xmlns:xlink="http://www.w3. org/1999/xlink" xlink:href="02i "/] on cohomology. We observe that the growth rate of ║ f n *║ is invariant under bimeromorphic conjugacy, and that by conjugating one can always arrange that f n * = f * n . We show that the sequence ║ f n *║ can be bounded, grow linearly, grow quadratically, or grow exponentially. In the first three cases, we show that after conjugating, f is an automorphism virtually isotopic to the identity, f preserves a rational fibration, or f preserves an elliptic fibration, respectively. In the last case, we show that there is a unique (up to scaling) expanding eigenvector θ+ for f *, that θ+ is nef, and that f is bimeromorphically conjugate to an automorphism if and only if θ 2 + = 0. We go on in this case to construct a dynamically natural positive current representing θ+, and we study the growth rate of periodic orbits of f . We conclude by illustrating our results with a particular family of examples.
Parallelizing MiniSat

The Boolean satisfiability (SAT) problem asks whether the variables in a given Boolean formula can be assigned in such a way that the formula evaluates to true. Given a Boolean formula, a SAT solver tries to find a set of satisfying assignments or declares that the formula is unsatisfiable. In this project, we implemented a parallel SAT solver using the Cilk multithreaded programming language. Our parallel implementation is based on MiniSat, a well regarded serial SAT solver known for its efficient implementation and small code base. This report outlines our parallelizing strategy and documents the implementation details of the search function. At the end of the document, we also presents some preliminary experimental results. The parallelized MiniSat has performance comparable to the original implementation when running on single processor. When running with multiple processors, however, the throughput of the solver does not quite scale as the number of processors increases.
Hybrid Technique Based on N-GRAM and Neural Networks for Classification of Mammographic Images

Various texture, shape, boundary features have been used previously to classify regions of interest in radiological mammograms into normal and abnormal categories. Although, bag-ofphrases or n-gram model has been effective in text representation for classification or retrieval of text, these approaches have not been widely explored for medical image processing. Our purpose is to represent regions of interest using an n-gram model, then deploy the n-gram features into a back-propagation trained neural network for classifying regions of interest into normal and abnormal categories. Experiments on the benchmark miniMIAS database show that the n-gram features can be effectively used for classification of mammograms into normal and abnormal categories in this way. Very promising results were obtained on fatty background tissue with 83.33% classification accuracy.
EURASIAN JOURNAL OF ECONOMICS AND FINANCE

This paper studies the changes in the pattern of Africa’s trade with China and OECD countries, and the impacts of these changes on sub-Saharan Africa’s economic growth. In the study, the country-level total exports and imports, as well as the commodity-based exports and imports are considered for 42 sub-Saharan African countries between 1980 and 2014. The results show that as the share of China in sub-Saharan Africa’s trade has significantly increased, a declining trend is observed for OECD countries, traditional trading partners. Despite changing trade links, the investigation of the commodity-based exports and imports indicate that the types of imported and exported commodities have not changed much for Africa. However, a strong link is observed between economic growth in SSA and its changing trade links from the OECD countries towards China at the total level as well as at the commodity level. The study concludes that there is an increase in the international competition for Africa’s commodities, and resulting in improvements in the terms of trade has led to higher income growth in the region.
Resource Booms, Growth and Poverty in Laos: What Can We Learn from Other Countries and Policy Simulations?

Laos is a small, open, least-developed country (LDC) in Southeast Asia. However, it is a resource-rich economy with over 570 identified mineral deposits. As a result, Laos has experienced massive inflows of foreign direct investment (FDI) in the mining and hydroelectricity sectors since 2003. Despite the likelihood that resource booms will carry both positive and negative impacts on the Lao economy, this issue has been underresearched in Laos. This study thus lays out a framework to quantify the impacts of resource booms on the macro economy and on poverty in Laos using a computable general equilibrium (CGE) model. We find that the higher capital stock and productivity led to increased value added, production, exports and investment in the mining sector, resulting in higher real GDP, exports and investment. Unfortunately, the associated Dutch disease effects (particularly real exchange rate appreciation) negatively impact real production and value added in agriculture, industry and government services.
Are You for Real? Learning Event Factuality in Croatian Texts

There is a certain discrepancy between real-world events and their representations in text (linguistic events or event mentions). The event mentions often refer to future or hypothetical events that have not actually occurred or whose occurrence is uncertain. In this paper we address the problem of predicting event factuality in Croatian texts using supervised machine learning. For each event mention, we aim to predict its polarity (whether the denoted event has actually happened) and its certainty (the level of confidence that the denoted event has happened). We use only lexically-based features, in order to investigate how well this problem may be addressed for a resource-poor language such as Croatian. Our preliminary results suggest that while predicting event polarity using only lexicallybased features is feasible, predicting event certainty mandates the use of more sophisticated features.
Precise MW Determination of Intact Proteins by Multiple Charge State Analysis of MALDI Generated Ions

The use of DHAP as MALDI matrix enhances the formation of multiple charged protein ions. These ions can be well calibrated by protein standards such as myoglobin or cytochrome c in the 8-20 kDa m/z range. The ultrafleXtreme with FlashDetector in combination with 4GS/s digitization rate can turn externally calibrated high quality data obtained from DHAP preparations into intact protein molecular weight (MW) information at hitherto unknown accuracy levels in the low ppm range. Accurate intact molecular weight analysis adds an additional characterization tool to the already considerable range of biopharmaceutical characterization workflows which are possible with Bruker MALDI-TOFs.
CONSIDERATIONS ON IDENTIFICATION OF DAMAGE PARAMETERS : A CASE STUDY

The steady growth of commercial codes in recent years has fostered applications of phenomenological approaches to plasticity modelling in industrial settings. Furthermore, metal forming operations involving large plastic deformations are subject to mechanical degradation thereby recommending use of damage models to failure predict. The present work is inserted within this framework in which identification of material parameters for a Gurson-type is discussed for a low alloy carbon steel.
Enhancement of water flow across a carbon nanotube

It is important to investigate how to enhance the flow rate of single-file water molecules across nanochannels. To our knowledge, all the existing methods are based on pressure gradients, external point charges or uniform/graded electric fields. Accordingly, these methods are all based on exogenous tools, and thus bring challenges for both energy-saving and miniaturisation. In contrast, here we manage to reveal an endogenously determined mechanism of flow enhancement. On the basis of molecular dynamics simulations, we investigate water permeation across a single-walled carbon nanotube (SWCNT A) in the presence of another SWCNT (SWCNT B). We find that the flow rate of the single-file water molecules across SWCNT A is enhanced for the case of unblocked SWCNT B compared with the rate for the case of blocked SWCNT B, and that this flow rate is determined by the separation between the two SWCNTs and the diameter of SWCNT B.
ENVIRONMENTAL AND HISTORICAL FACTORS DRIVING VEGETATION COMMUNITIES ON RUSSIAN ISLAND, COLUMBIA RIVER ESTUARY

Simenstad, for their excellent guidance and willing bequeathal of their wealth of knowledge and expertise. I would also like to extend huge thanks to Jennifer Burke, Miles Logsdon, and Earth Design Consultants for their indispensable GIS support. Much gratitude also goes to Dr. Perry Gayaldo for his generous help with grain size analysis methodology and to Dr. Liz Van Volkenburgh for the use of her freezing point depression osmometer. Taylor, and the rest of the CUH graduate students for their incredible intellectual support and project guidance. Last, but certainly not least, I'd like to thank my parents, without whose moral and financial support, my academic career would have been a much more difficult endeavor. 1 1.0 INTRODUCTION 1.1 Estuarine ecology overview Estuaries occur at the interface between a river and a body of salt water, and they are more specifically defined as: ―semi-enclosed coastal bodies of water which have a free connection with the open sea and within which sea water is measurably diluted with fresh water derived from land drainage‖ (Pritchard 1967). They are dynamic systems, with accretional and erosional forces from river and tidal influences constantly re-sculpting their shape and ecosystem processes. They exhibit highly variable salinities, depending on the proportion of freshwater to tidal influence they receive (Day et al. 1989, Mitsch and Gosselink 2000). Estuaries tend to be sheltered from high-energy waves and receive ample water and nutrients from river and tide-flow, therefore setting the stage for development of productive marsh habitat (Chapman 1960, Day et al. 1989). Estuarine marshes tend to develop initially on mud or sand flats that are close to sea level, and continue to grow in elevation with sediment accretion (Day et al. 1989, Eilers 1975). Also characteristic of these marshes are extensive networks of dendritic tidal channels that, unlike many dynamic features in an estuary, tend to remain in a fixed position once established (Day et al. 1989, Pestrong 1965, Redfield 1965). These channels fill with the tides, and as water levels rise and spill onto the surface of the marsh, suspended sediments tend to drop out along channel margins, thus producing a levee effect along the banks of tidal creeks (Day 1989, Eilers 1975). As mentioned, estuarine marshes, especially those of lower salinity, are highly productive systems, with plant communities that tend to be dominated by graminoids (tall reeds, grasses, and sedges), broad-leaved monocots, and floating plants, and energy dynamics …
CONTROL OF COATING THICKNESS IN A TINPLATE LINE

Abstract In a tinplate line the coating thickness can be controlled by means of the line speed and current applied. A control strategy has been developed that calculates the maximum possible speed and the total necessary current, distributing it into the available rectifiers. The equations used for the calculations are based on a mathematical model obtained using Genetic Programming.
Pomegranate Iron (III) Reducing Antioxidant Capacity (iRAC) Compared to ABTS Radical Quenching

Pomegranate juice (PJ) has total antioxidant capacity (TAC) which is reportedly higher 13 compared to other common beverages. This short study aimed to evaluate the TAC of 14 commercial PJ and pomegranate fruit in terms of a newly described iron (III) reducing 15 antioxidant capacity (iRAC) and to compare with ABTS free radical quenching activity. 16 Commercial PJ, freeze-dried pomegranate, and oven dried-pomegranate were analyzed. The 17 total phenols content (TPC) was also assessed by the Folin-Ciocalteu method. The calibration 18 results for iRAC were comparable to ABTS and Folin-Ciocalteu methods in terms of linearity (R2 19 > 0.99), sensitivity and precision. The TAC for PJ expressed as trolox equivalent antioxidant 20 capacity (TEAC) was 33.4 ± 0.5 mM with the iRAC method and 36.3 ± 2.1 mM using the ABTS 21 method. For dried pomegranates, TAC was 89–110 mmol/100g or 76.0 ± 4.3 mmol/100 g using 22 iRAC and ABTS methods, respectively. Freeze-dried pomegranate had 15% higher TAC 23 compared with oven-dried pomegranate. In conclusion, pomegranate has high TAC as 24 evaluated by the iRAC and ABTS methods, though variations occur due to the type of cultivar, 25 geographic origin, processing and other factors. The study is relevant for attempts to refine food 26 composition data for pomegranate and other functional foods. 27
Two reliable methods for estimating the mechanical parameters of a rotating three-inertia system

Two methods for estimating the mechanical parameters of a rotating drive system that can be treated as a resonant 3-inertia system, are proposed. The accuracy of the estimation results is sufficient in order to design a state controller, which damps both resonances actively. Synopsis The mechanics of rotating drive systems normally consist of several inertias, which are joined together by elastic shafts. That is why they are resonant and only weakly damped. In order to control such systems, the mechanical parameters have to be known. In literature [ljung], [soderstrom], [isermann] several estimation methods are well known. The lowest resonant frequencies of known systems [wolff], [singer], [lorenz] are less than 100 Hz. Normally, those systems have been treated as 2-inertia systems. Especially in [singer], moreover one inertia has been known before and the positions both of the motor and the load have been evaluated. The resonant frequencies of modern high-dynamic drive systems are often much higher than 100 Hz. The dynamic range of modern control methods, e.g. DMTC (Direct Mean Torque Control) [flach], makes it possible to damp resonances of several 100 Hz, actively [pahlke]. Therefore, the mechanical parameters such systems have to be known accurately enough. Experimental set-ups
3-D CNN Models for Far-Field Multi-Channel Speech Recognition

Automatic speech recognition (ASR) in far-field reverberant environments, especially when involving natural conversational multiparty speech conditions, is challenging even with the state-of-the-art recognition methodologies. The two main issues are artifacts in the signal due to reverberation and the presence of multiple speakers. In this paper, we propose a three dimensional (3-D) convolutional neural network (CNN) architecture for multi-channel far-field ASR. This architecture processes time, frequency & channel dimensions of the input spectrogram to learn representations using convolutional layers. Experiments are performed on the REVERB challenge LVCSR task and the augmented multi-party (AMI) LVCSR task using the array microphone recordings. The proposed method shows improvements over the baseline system that uses beamforming of the multi-channel audio along with a 2-D conventional CNN framework (absolute improvements of 1.1 % over the beamformed baseline system on AMI dataset).
Learning Actions from the Identity in the Web

This paper proposes an efficient and simple method for identity recognition in uncontrolled videos. The idea is to use images collected from the web to learn representations of actions related with identity, use this knowledge to automatically annotate identity in videos. Our approach is unsupervised where it can identify the identity of human in the video like YouTube directly through the knowledge of his actions. Its benefits are two-fold: 1) we can improve retrieval of identity images, and 2) we can collect a database of action poses related with identity, which can then be used in tagging videos. We present the simple experimental evidence that using action images related with identity collected from the web, annotating identity is possible.
Challenges in vitamin D analysis / Izazovi u analizi vitamina D

Summary Vitamin D is an important determinant for the regulation of calcium and phosphorus levels and mineralization of the bone. The most reliable indicator of vitamin D status is the measurement of plasma or serum 25OH-D concentration. Several studies reported discrepancies between the results of assays. These high variabilities in 25OH-D measurements are due to used assay technologies and lack of standardization against the reference materials. Different assays have been employed for the measurement of 25OHD levels: Competitive Protein Binding Assays, immunoassays, direct detection methods. Choosing an assay platform is important both for clinical laboratory professionals and researchers, and several factors affect this process. Recently, liquid chromatography and tandem mass spectrometry is an alternative method to traditional assays and provides higher specificity and sensitivity than many assays; therefore, it has been suggested as a candidate reference method for circulating 25OH-D3. Standardization of methods for the quantification of 25OH-D by using the human-based samples would reduce the inter-method variability. The best way for laboratories to demonstrate the accuracy of their results is by participating in the external quality assessment scheme. Standardization of the assays is also required to provide clinicians with the accurate tools to diagnose hypovitaminosis. In addition, assay-specific decision limits are needed to define appropriate thresholds of treatment. Kratak sadržaj Vitamin D je va`na determinanta u regulaciji nivoa kalcijuma i fosfora i mineralizaciji kostiju. Naj - pouz daniji indikator statusa vitamina D je odre|ivanje koncentracije 25OH-D u plazmi ili serumu. Nekoliko studija je pokazalo neslaganja izme|u rezultata razli~itih testova.

Metal/Polymer Based Stretchable Antenna for Constant Frequency Far‐Field Communication in Wearable Electronics

Body integrated wearable electronics can be used for advanced health monitoring, security, and wellness. Due to the complex, asymmetric surface of human body and atypical motion such as stretching in elbow, finger joints, wrist, knee, ankle, etc. electronics integrated to body need to be physically flexible, conforming, and stretchable. In that context, state‐of‐the‐art electronics are unusable due to their bulky, rigid, and brittle framework. Therefore, it is critical to develop stretchable electronics which can physically stretch to absorb the strain associated with body movements. While research in stretchable electronics has started to gain momentum, a stretchable antenna which can perform far‐field communications and can operate at constant frequency, such that physical shape modulation will not compromise its functionality, is yet to be realized. Here, a stretchable antenna is shown, using a low‐cost metal (copper) on flexible polymeric platform, which functions at constant frequency of 2.45 GHz, for far‐field applications. While mounted on a stretchable fabric worn by a human subject, the fabricated antenna communicated at a distance of 80 m with 1.25 mW transmitted power. This work shows an integration strategy from compact antenna design to its practical experimentation for enhanced data communication capability in future generation wearable electronics.
Sometimes You Win, Sometimes You Learn – Success Factors in Reward-Based Crowdfunding

Crowdfunding has enabled various entrepreneurs, artists and other individuals and organisations to bring projects to life. Despite all success stories, 63% of all projects initiated on the biggest crowdfunding platform kickstarter.com and 46% of all projects initiated on the biggest German crowdfunding platform startnext.com, do not raise enough money to be realised. This study investigates which factors beyond project quality and personal network impact the success of a crowdfunding campaign. Using data collected from startnext.com, we analyse the impact of six factors on the probability of success and provide practical recommendations for initiators. The six factors we analyse are: inclusion of a video, length of project description, communication with backers, curation by a third party, crowdfunding activity of the project initiator and number of rewards. In particular, we show that the inclusion of a video, an intensive communication with backers via blog posts, a history in supporting projects and the creation of a variety of rewards can significantly increase the likelihood that a project succeeds.
Small Steps, Big Leap: Physiological Feeding Regime Helps Infant with Ultra-short Bowel Syndrome to Achieve Full Enteral Autonomy Early

Aggressive and continuous feeding regimes for children with short bowel syndrome (SBS) have been recommended in literatures for decades. Adequate bowel rest has not been addressed for bowel adaptation in literature previously. Our patient is a term infant girl with ultra short bowel after massive small bowel resection for volvulus on the third day of life. When on aggressive feeding regimen, she developed rectal bleeding and shock. After bowel rest, milk feeding was resumed at a volume corresponding to her remnant bowel length. She was on small bolus feeds via syringe every 2 hours. The advancement interval was according to the intestinal mucosal turnover time. The total nutrient given by oral and intra-venous routes were as for usual infant, about 100 kcal/kg/day. She achieved full enteral autonomy by 9.5-month-old with a body weight of 8.54 kg. She was discharged by 10.5-month-old. In our physiological feeding regime, tube feeding, prokinetics, anti-diarrheal agents, cyclic antibiotics, probiotics, hormonal therapy, or repeated bowel operations were not needed. Different from the usual recommendations for infants with SBS, excessive milk feeding was not needed all along and even beyond enteral autonomy.
