The effect of flow and orography on the spatial distribution of the very short-term predictability of rainfall

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract The spatial distribution and scale-dependence of the very-short term predictability of precipitation by Lagrangian persistence is studied under different flow regimes in connection with the presence of orographic features. Data from the weather radar composite of eastern Victoria, Australia, a 500 km × 500 km domain at 10 min temporal and 5 2 km × 2 km spatial resolutions, covering the period from February 2011 to October 2012, were used for the analyses. The scale-dependence of the predictability of precipitation is considered by decomposing the radar rainfall field into an 8-levels multi-plicative cascade using a Fast Fourier Transform. The rate of temporal development of precipitation in Lagrangian coordinates is estimated at each level of the cascade under 10 different flow regimes, which are stratified by applying a k-means clustering algorithm on the diagnosed velocity fields. The predictability of precipitation is measured by its lifetime, which is derived by integrating the Lagrangian auto-correlation function. The lifetimes were found to depend on the scale of the feature as a power law, which is known as dynamic scaling, and to vary as a function of flow regime. The lifetimes also 15 exhibit significant spatial variability and are approximately a factor two longer on the upwind compared with the downwind slopes of terrain features. The scaling exponent of the spatial power spectrum also shows interesting geographical differences. These findings provide opportunities to perform spatially inhomogeneous stochastic simulations of space-time precipitation to account for the presence of orography, which may 20 be integrated into design storm simulations and stochastic precipitation nowcasting systems.
A COMPUTATION METHOD IN PERFORMANCE EVALUATION IN CELLULAR COMMUNICATION NETWORK UNDER THE GENERAL DISTRIBUTION MODEL

The paper considers the computation method in the performance evaluation of cellular network in the phase-type distribution assumptions that the channel holding times induced from mobility are modeled by well-fitted distributions to reflect an actual situation. When ww consider a phase-type distribution model instead of exponential distribution, the complexity of the computation increase exponential even though the accuracy is improved. We consider an efficient numerical algorithm to compute the performance evaluations in cellular networks such as a handoff call dropping probability, new call blocking probability, and handoff arrival rate. Numerical experiment shows that numerical analysis results are well approximated to the results of simulation.
Acute High-Dose and Chronic Lifetime Exposure to Alcohol Consumption and Differentiated Thyroid Cancer: T-CALOS Korea

Background This study evaluated the effects of acute high-dose and chronic lifetime exposure to alcohol and exposure patterns on the development of differentiated thyroid cancer (DTC). Methods The Thyroid Cancer Longitudinal Study (T-CALOS) included 2,258 DTC patients (449 men and 1,809 women) and 22,580 healthy participants (4,490 men and 18,090 women) who were individually matched by age, gender, and enrollment year. In-person interviews were conducted with a structured questionnaire to obtain epidemiologic data. Clinicopathologic features of the patients were obtained by chart reviews. Odds ratios (ORs) and 95% confidence intervals (95%CI) were estimated using conditional regression models. Results While light or moderate drinking behavior was related to a reduced risk of DTC, acute heavy alcohol consumption (151 g or more per event or on a single occasion) was associated with increased risks in men (OR = 2.22, 95%CI = 1.27–3.87) and women (OR = 3.61, 95%CI = 1.52–8.58) compared with never-drinkers. The consumption of alcohol for 31 or more years was a significant risk factor for DTC for both men (31–40 years: OR = 1.58, 95%CI = 1.10–2.28; 41+ years: OR = 3.46, 95%CI = 2.06–5.80) and women (31–40 years: OR = 2.18, 95%CI = 1.62–2.92; 41+ years: OR = 2.71, 95%CI = 1.36–5.05) compared with never-drinkers. The consumption of a large amount of alcohol on a single occasion was also a significant risk factor, even after restricting DTC outcomes to tumor size, lymph node metastasis, extrathyroidal extension and TNM stage. Conclusion The findings of this study suggest that the threshold effects of acute high-dose alcohol consumption and long-term alcohol consumption are linked to an increased risk of DTC.
A Variational Approach to the Stationary Solutions of the Burgers Equation

We consider the viscous Burgers equation on a bounded interval with inhomogeneous Dirichlet boundary conditions. Following the variational framework introduced by Bertini et al. [Comm. Pure Appl. Math., 64 (2011), pp. 649–696], we analyze a Lyapunov functional for such an equation which gives the large deviations asymptotic of a stochastic interacting particles model associated to the Burgers equation. We discuss the asymptotic behavior of this energy functional, whose minimizer is given by the unique stationary solution, as the length of the interval diverges. In particular, we focus on boundary data corresponding to a standing wave solution to the Burgers equation in the whole line. In this case, the limiting functional has a one-parameter family of minimizers and we compute the sharp asymptotic cost corresponding to a given shift of the stationary solution.
Familial coaggregation of cryptorchidism, hypospadias, and testicular germ cell cancer: a nationwide cohort study.

BACKGROUND Cryptorchidism, hypospadias, and testicular germ cell cancer (TGCC) may be symptoms of a testicular dysgenesis syndrome that manifests during fetal life. To address the inheritability of this syndrome, we examined whether family history of cryptorchidism or hypospadias is associated with an increased risk of TGCC. METHODS A total of 2,159,883 men born since 1953, identified through Danish health registers, were followed from April 2, 1968, through May 31, 2008. First-, second-, and third-degree relatives were identified in the Danish Family Relations Database; cryptorchidism and hypospadias patients were identified in the Danish Hospital Discharge Register; and TGCC patients were identified in the Danish Cancer Register. Poisson regression was used to calculate the risk ratio for TGCC by family history of cryptorchidism or hypospadias. RESULTS A total of 5441 patients developed TGCC. A personal history of cryptorchidism or hypospadias was associated with an increased relative risk (RR) of developing TGCC (RR = 3.71, 95% confidence interval [CI] = 3.29 to 4.19; and RR = 2.13, 95% CI = 1.26 to 3.61, respectively). For example, in men in their thirties, the overall rate per 100 000 is 25.1 in the cohort, but 88.6 and 55.4 in men born with cryptorchidism or hypospadias, respectively. In contrast, relatives of a hypospadias patient did not have a statistically significantly increased risk of TGCC nor did the first- and second-degree relatives of cryptorchidism patients. However, we found a small increased risk of TGCC for third-degree relatives of patients with cryptorchidism. CONCLUSIONS Having hypospadias or cryptorchidism was associated with an increased risk of developing TGCC. However, our finding that family history of hypospadias or cryptorchidism generally was not associated with increased risk of developing TGCC does not support the hypothesis of shared inheritability of cryptorchidism, hypospadias, and TGCC.

Conclusion: The use of auditory prosthesis provided the improvement of the domains of the quality of life, what it reflected consequently in one better auto-confidence and in the long run in the reduction of the fear of fall in aged with sensorineural auditory loss.
Uses of Rhetorical Reasoning Theories in Business Communication Researches

Objectives: By literature review, this paper tries to find how rhetorical reasoning models and theories have been used in business communication both in industry and academia and answer the following questions: 1) Is rhetorical reasoning important for persuasion in business? 2) What kinds of rhetorical reasoning methods have been used in business communication? Methods: Dissertations and journal articles from RISS (Research Information Sharing Service) and Google Scholar were gathered. Academic sources were reviewed based on the basic frame of research: Domain, Method, and Results. Results: Theories and models of Perelman, Toulmin, and van Eemeren have been used to explain various phenomena in the field of business. Business fields in this paper include advertising, bank annual reports, downsizing reports, and policy decision making processes. Conclusions: Rhetorical reasoning is a widely used method in business communication. Several suggestions for future researches are: First, more rhetorical theories and models are needed to be used to business communication research. Second, existing rhetorical reasoning models like the argumentation model of Toulmin need to be tested in more diverse fields of business communication. Third, in addition to text, rhetorical, content analysis, other kinds of research methods such as experiments will be useful for expanding the boundaries of business communication research based on rhetorical reasoning theories.
Prepartitioning as a way to mesh subdomains in parallel

We introduce a new method to mesh a physical domain in parallel. Given a domain deened by a set of boundary facets, we construct a separator of it. As a result, we obtain several subdomains, each of them being deened by a set of boundary facets. Naturally, the separation step can be applied recursively to increase the number of subdomains, or to reduce the size of one subdomain. Then, a classical mesh generator is applied to achieve the computation. Along with the theoretical background that allows to mesh such a separator (this process is called prepartitioning), we show how the method performs on a large set of industrial examples. Some parallel simulations have been done, and the results for large examples are promising.
Bayesian Variable Selection and Estimation of Risk Premiums in the APT model

Empirical tests of the arbitrage pricing theory using measured variables rely on the accuracy of standard inferential theory in approximating the distribution of the estimated risk premiums and factor betas. The techniques employed thus far perform factor selection and model inference sequentially. Recent advances in Bayesian variable selection are adapted to an approximate factor model to investigate the role of measured economic variables in the pricing of securities. In finite samples, exact statistical inference is carried out using posterior distributions of functions of risk premiums and factor betas. The role of the panel dimensions in posterior inference is investigated. New empirical evidence is found of time-varying risk premiums with higher and more volatile expected compensation for bearing systematic risk during contraction phases. In addition, investors are rewarded for exposure to “Economic” risk. JEL Classification: C1, C22, C52
Transition-Based Neural Word Segmentation

Character-based and word-based methods are two different solutions for Chinese word segmentation, the former exploiting sequence labeling models over characters and the latter using word-level features. Neural models have been exploited for character-based Chinese word segmentation, giving high accuracies by making use of external character embeddings, yet requiring less feature engineering. In this paper, we study a neural model for word-based Chinese word segmentation, by replacing the manually-designed discrete features with neural features in a transition-based word segmentation framework. Experimental results demonstrate that word features lead to comparable performance to the best systems in the literature, and a further combination of discrete and neural features obtains top accuracies on several benchmarks.
Hard underlying event correction to inclusive jet cross sections

Jets observed in hadron-hadron scattering contain a contribution from the ``underlying event'' that is produced by spectator interactions taking place incoherently with the major parton-parton collision, due to the extended composite structure of the colliding hadrons. Using a recent measurement of the double parton interaction rate, we calculate that the underlying event may be $2$--$3$ times stronger than generally assumed, as a result of semi-hard perturbative multiple-parton interactions. This can have an important influence on the inclusive jet cross section at moderate values of ${E}_{T},$ persisting at the $5--10%$ level to the largest observable ${E}_{T}. $ We show how the underlying event can be measured accurately using a generalization of a method first proposed by Marchesini and Webber.
Synchronization with multiprocessor caches

A new lock-based cache scheme which incorporates synchronization into the cache coherency mechanism is presented. With this scheme high-level synchronization primitives, as well as low-level ones, can be implemented without excessive overhead. Cost functions for well-known synchronization methods are derived for invalidation schemes, write update schemes, and the authors' lock-based scheme. To predict the performance implications of the new scheme accurately, a new simulation model embodying a widely accepted paradigm of parallel programming is developed. It is shown that that authors' lock-based protocol outperforms existing cache protocols. <<ETX>>
The guardian model and primitives for exception handling in distributed systems

This work presents an abstraction called guardian for exception handling in distributed and concurrent systems that use coordinated exception handling. This model addresses two fundamental problems with distributed exception handling in a group of asynchronous processes. The first is to perform recovery when multiple exceptions are concurrently signaled. The second is to determine the correct context in which a process should execute its exception handling actions. Several schemes have been proposed in the past to address these problems. These are based on structuring a distributed program as atomic actions based on conversations or transactions and resolving multiple concurrent exceptions into a single one. The guardian in a distributed program represents the abstraction of a global exception handler, which encapsulates rules for handling concurrent exceptions and directing each process to the semantically correct context for executing its recovery actions. Its programming primitives and the underlying distributed execution model are presented here. In contrast to the existing approaches, this model is more basic and can be used to implement or enhance the existing schemes. Using several examples we illustrate the capabilities of this model. Finally, its advantages and limitations are discussed in contrast to existing approaches.

Femoral and Tibial Tunnel Diameter and Bioabsorbable Screw Findings After Double-Bundle ACL Reconstruction in 5-Year Clinical and MRI Follow-up

Background: Tunnel enlargement is frequently seen in short-term follow-up after anterior cruciate ligament reconstruction (ACLR). According to new evidence, tunnel enlargement may be followed by tunnel narrowing, but the long-term evolution of the tunnels is currently unknown. Hypothesis/Purpose: The hypothesis was that tunnel enlargement is followed by tunnel narrowing caused by ossification as seen in follow-up using magnetic resonance imaging (MRI). The purpose of this study was to evaluate the ossification pattern of the tunnels, the communication of the 2 femoral and 2 tibial tunnels, and screw absorption findings in MRI. Study Design: Case series; Level of evidence, 4. Methods: Thirty-one patients underwent anatomic double-bundle ACLR with hamstring grafts and bioabsorbable interference screw fixation and were followed with MRI and clinical evaluation at 2 and 5 years postoperatively. Results: The mean tunnel enlargement at 2 years was 58% and reduced to 46% at 5 years. Tunnel ossification resulted in evenly narrowed tunnels in 44%, in conical tunnels in 48%, and fully ossified tunnels in 8%. Tunnel communication increased from 13% to 23% in the femur and from 19% to 23% in the tibia between 2 and 5 years and was not associated with knee laxity. At 5 years, 54% of the screws were not visible, with 35% of the screws replaced by a cyst and 19% fully ossified. Tunnel cysts were not associated with worse patient-reported outcomes or knee laxity. Patients with a tibial anteromedial tunnel cyst had higher Lysholm scores than patients without a cyst (93 and 84, P = .03). Conclusion: Tunnel enlargement was followed by tunnel narrowing in 5-year follow-up after double-bundle ACLR. Tunnel communication and tunnel cysts were frequent MRI findings and not associated with adverse clinical evaluation results.
Reliable Task Design for Descriptive Crowdsourcing

Crowdsourcing offers a valuable method to improve information retrieval indexing by using humans to improve the indexable data about documents or entities. Human contributions open the door to latent information, subjective judgments, and other encoding of difficult to extract data. However, such contributions are also subject to variance from the inconsistencies of human interpretation. The proposed dissertation studies the problem of such variance in crowdsourcing for information retrieval, and investigates how it can be controlled both in already collected data and in collecting new data. This paper outlines a corresponding study where the effect of different contribution system designs on the resulting data is compared in paid crowdsourcing environments. At the heart of this study is the assumption of honest-but-biased contributors. Rather than focusing on finding dishonest or unreliable contributors, a well-studied problem in crowdsourcing, this study focuses on strategies that understand the quirks and inconsistencies of humans in trying to account data reliability problems.
Coating Hidroksiapatit pada Logam Stainless Steel 316L Menggunakan Metode DIP Coating dengan Variabel Temperatur Sintering dan Komposisi Air dalam Suspensi

Stainless Steel 316L is metal that can be used as a bone plate, but it has low biocompatibility. To achieve better biocompatibility with bone, Stainless Steel 316L can be coated with hydroxyapatite. Hydroxyapatite (HA) is the main inorganic phase of human bone with a composition around 65% of our bone. Dip coating techniques was used to applyhydroxyapatite into Stainless Steel 316L. Stainless Steel 316L with a size of 2x1x0,1 cm was dipped into a suspension containing HA, sago starch and water mixed with a rate of 250 rpm for 20 hours. Suspension were prepared with compositions 16 gram, 18 gram and 20 gram aquadest. And then coating HA were dried in oven at temperature 110 °C for 30 minutes.Coating HA were sintered at temperatures of 600°C, 700°C and 800 °C for 1 hour. SEM observation showed that the thickness of HA coating composition of 20 gram, 18 gram and16 gram increased in the range of 42 – 144 μm. Maximum shear strength obtained in this research was 11,78 MPa.
