Chinese Song Iambics Generation with Neural Attention-Based Model

Learning and generating Chinese poems is a charming yet challenging task. Traditional approaches involve various language modeling and machine translation techniques, however, they perform not as well when generating poems with complex pattern constraints, for example Song iambics, a famous type of poems that involve variable-length sentences and strict rhythmic patterns. This paper applies the attention-based sequence-to-sequence model to generate Chinese Song iambics. Specifically, we encode the cue sentences by a bi-directional Long-Short Term Memory (LSTM) model and then predict the entire iambic with the information provided by the encoder, in the form of an attention-based LSTM that can regularize the generation process by the fine structure of the input cues. Several techniques are investigated to improve the model, including global context integration, hybrid style training, character vector initialization and adaptation. Both the automatic and subjective evaluation results show that our model indeed can learn the complex structural and rhythmic patterns of Song iambics, and the generation is rather successful.
Temporal Gene Expression Profiling during Rat Femoral Marrow Ablation-Induced Intramembranous Bone Regeneration

Enhanced understanding of differential gene expression and biological pathways associated with distinct phases of intramembranous bone regeneration following femoral marrow ablation surgery will improve future advancements regarding osseointegration of joint replacement implants, biomaterials design, and bone tissue engineering. A rat femoral marrow ablation model was performed and genome-wide microarray data were obtained from samples at 1, 3, 5, 7, 10, 14, 28, and 56 days post-ablation, with intact bones serving as controls at Day 0. Bayesian model-based clustering produced eight distinct groups amongst 9,062 significant gene probe sets based on similar temporal expression profiles, which were further categorized into three major temporal classes of increased, variable, and decreased expression. Osteoblastic- and osteoclastic-associated genes were found to be significantly expressed within the increased expression groups. Chondrogenesis was not detected histologically. Adipogenic marker genes were found within variable/decreased expression groups, emphasizing that adipogenesis was inhibited during osteogenesis. Differential biological processes and pathways associated with each major temporal group were identified, and significantly expressed genes involved were visually represented by heat maps. It was determined that the increased expression group exclusively contains genes involved in pathways for matrix metalloproteinases (MMPs), Wnt signaling, TGF-β signaling, and inflammatory pathways. Only the variable expression group contains genes associated with glycolysis and gluconeogenesis, the notch signaling pathway, natural killer cell mediated cytotoxicity, and the B cell receptor signaling pathway. The decreased group exclusively consists of genes involved in heme biosynthesis, the p53 signaling pathway, and the hematopoietic cell lineage. Significant biological pathways and transcription factors expressed at each time point post-ablation were also identified. These data present the first temporal gene expression profiling analysis of the rat genome during intramembranous bone regeneration induced by femoral marrow ablation.
RF powering of millimeter- and submillimeter-sized neural prosthetic implants

The size of the transducers for neural stimulation has shrunk steadily with application of thin-film techniques to electrode design. The feasibility is examined of designing millimeter- and submillimeter-sized power sources based on RF coupling that could be integrated into these implants to provide power without a tethering power cable. The coupling between a transmitter coil and receiver coil when the coil diameters are markedly different is analyzed, and for these circumstances, a simple Thevenin equivalent model is developed to describe the power transmission between the transmitter and receiver. The equivalent circuit developed gives insight into the way that coil diameters, frequency, and turns affect coupling between large and small coils. Several examples demonstrate that milliwatt range power sources can be implemented with millimeter- and submillimeter-diameter receivers. <<ETX>>
Model Selection in Reinforcement Learning

We consider the challenge of automating parameter tuning in reinforcement learning. More specifically, we consider the batch (off-line, non-interactive) reinforcement learning setting and the problem of learning an action-value function with a small Bellman error. We propose a complexity regularization-based model selection algorithm and prove its adaptivity : the procedure is shown to perform almost as well as if the best parameter setting was known ahead of time. We also discuss other approaches to derive adaptive procedures in reinforcement learning.
Assimilation of Ice Concentration in an Ice–Ocean Model

Abstract Ice concentration is a critical parameter of the polar marine environment because of the large effect sea ice has on the surface albedo and heat exchange between the atmosphere and the ocean. Simulations of the energy exchange processes in models would benefit if the ice concentration were represented more accurately. Reanalysis simulations that use historical wind and temperature fields may develop erroneous ice concentration estimates; these can be corrected by using observed ice concentration fields. The ice concentration assimilation presented here is a new method based on nudging the model ice concentration toward the observed concentration in a manner that emphasizes the ice extent and minimizes the effect of observational errors in the interior of the pack. The nudging weight is a nonlinear function of the difference between the model and the observed ice concentration. The simulated ice extent is improved with the assimilation of ice concentration but is not identical to the observed exte.
Book Reviews : Michael L. Gerlach: Alliance Capitalism — The Social Organization of Japanese Business

detailed and most interesting books which have been published on the industrial organization of Japan. The book is based upon empirical research carried out by the author himself using a large-scale database on important business relationships among 250 large Japanese and American corporations as well as information gathered in archives and in interviews with executives. This is only one reason why it should be on the shelf of all those interested in the interorganizational structure of keiretsu, in the nature of subcontracting relationships of Japanese firms, and in the intercorporate flow of goods and capital among firms, banks and other institutions. A second reason why the book should be read by those interested in the structure and the functioning of industrial organization in Japan is the fact that it is one of the few which takes a true network perspective
Effect of Ligation Method on Maxillary Arch Force/Moment Systems for a Simulated Lingual Incisor Malalignment

Introduction: The objectives of this study were to determine whether there is a difference in the magnitude of forces and moments produced by elastic ligation when compared to passive ligation, and whether these forces and moments propagate differently along the arch for the two ligation types. A lingual incisor malalignment was used in this study. Methods: The Orthodontic Simulator (OSIM) was used to quantify the three-dimensional forces and moments applied on the teeth given a lingually displaced incisor. A repeated measures MANOVA was performed to statistically analyze the data. Results: The interaction factor illustrated convincing evidence that there is a difference in maximum force and moment values for all outcome variables between ligation types considering all tooth positions along the arch. The mean differences for FX and FY between ligation types were found to be clinically significant, with values for elastic ligation consistently higher than passive ligation. Conclusion: It was found that the maximum forces and moments produced by elastic ligation are greater than those produced by passive ligation and that the magnitude of this difference for the mesiodistal and buccolingual forces is clinically relevant. Additionally, it was determined that elastic ligation causes forces and moments to propagate further along the arch than passive ligation for all outcome variables.
Wood-Inhabiting Beetles in Low Stumps, High Stumps and Logs on Boreal Clear-Cuts: Implications for Dead Wood Management

The increasing demand for biofuels from logging residues require serious attention on the importance of dead wood substrates on clear-cuts for the many forestry-intolerant saproxylic (wood-inhabiting) species. In particular, the emerging harvest of low stumps motivates further study of these substrates. On ten clear-cuts we compared the species richness, abundance and species composition of saproxylic beetles hatching from four to nine year old low stumps, high stumps and logs of Norway spruce. By using emergence traps we collected a total of 2,670 saproxylic beetles among 195 species during the summers of 2006, 2007 and 2009. We found that the species assemblages differed significantly between high stumps and logs all three years. The species assemblages of low stumps, on the other hand, were intermediate to those found in logs and high stumps. There were also significant difference in species richness between the three examined years, and we found significant effect of substrate type on richness of predators and fungivores. As shown in previous studies of low stumps on clear-cuts they can sustain large numbers of different saproxylic beetles, including red-listed species. Our study does, in addition to this fact, highlight a possible problem in creating just one type of substrate as a tool for conservation in forestry. Species assemblages in high stumps did not differ significantly from those found in low stumps. Instead logs, which constitute a scarcer substrate type on clear-cuts, provided habitat for a more distinct assemblage of saproxylic species than high stumps. It can therefore be questioned whether high stumps are an optimal tool for nature conservation in clear-cutting forestry. Our results also indicate that low stumps constitute an equally important substrate as high stumps and logs, and we therefore suggest that stump harvesting is done after carefully evaluating measures to provide habitat for saproxylic organisms.
Academic Examinations Significantly Impact Immune Responses, but Not Lung Function, in Healthy and Well-Managed Asthmatic Adolescents

The influence of academic examinations on immunity and lung function was investigated in 64 adolescents to determine if stress-related changes would differ between healthy and asthmatic students. Blood samples were collected on three occasions: 1 month prior, during, and 2-3 weeks after exams. Leukocyte subsets were enumerated, and in vitro assays were conducted to assess lymphocyte proliferative and cytolytic responses and neutrophil production of superoxides. Examinations elicited significant changes in several lymphocyte subsets and marked alterations in the three functional measures in all students. However, the magnitude and pattern of change did not differ between healthy and asthmatic students. Similarly, neither mild nor more severe asthmatics showed an exam-related decrement in lung function, as reflected by peak expiratory flow rate. This research validated that examinations are a salient cause of altered immune responses, but indicates that there is not a concomitant aggravation of inflammatory disease in well-managed asthmatics.
Better survival in women with resected hepatocellular carcinoma is not related to tumor proliferation or expression of hormone receptors.

OBJECTIVE There is a well known male predominance in hepatocellular carcinoma (HCC). Moreover, female patients with HCC have better survival and lower recurrence rates after surgical resection. We previously showed that the better prognosis in female patients is related to a higher incidence of tumor encapsulation and less invasive tumors. However, the underlying mechanism is still obscure. METHODS In this study, we examined the cell proliferative indices (expression of proliferative cell nuclear antigen (PCNA) and Ki-67 antigen using MIB1 antibody) and expression of the estrogen and progesterone receptors (ERs and PRs, respectively) in 71 patients with resected HCC. These were correlated with the pathological features of the tumors and the survival rates of patients. RESULTS Female patients with HCC had significantly better actuarial and disease-free survival rates than male patients (p = 0.010 and 0.004, respectively). Tumor PCNA scores, represented by positively stained nuclei per 1000 tumor cells, were significantly higher in tumors showing venous permeation (p = 0.034), positive resection margins (p = 0.011), and absence of bile production (p = 0.008). Higher tumor MIB1 scores were seen in tumors that had poorer cellular differentiation (p = 0.002) and no tumor capsules (p = 0.042). However, both tumor PCNA and MIB1 scores did not differ significantly between female and male patients. ERs were detected in the tumor cells in 23.9% of tumors, and PRs were detected in 14.3%. Expression of both ER and PR was not influenced by gender. CONCLUSIONS Women with HCC had significantly better survival and lower tumor recurrence rates. However, significant differences in cellular proliferation indices and expression of ER and PR were not observed between men and women to explain the difference in survival rate.
Semantic Information Extraction for Improved Word Embeddings

Word embeddings have recently proven useful in a number of different applications that deal with natural language. Such embeddings succinctly reflect semantic similarities between words based on their sentence-internal contexts in large corpora. In this paper, we show that information extraction techniques provide valuable additional evidence of semantic relationships that can be exploited when producing word embeddings. We propose a joint model to train word embeddings both on regular context information and on more explicit semantic extractions. The word vectors obtained from such an augmented joint training show improved results on word similarity tasks, suggesting that they can be useful in applications that involve word meanings.
Clinical significance of oligohydramnios in patients with preterm labor and intact membranes*,**

Abstract Objective: To determine the frequency and clinical significance of oligohydramnios in patients with preterm labor and intact membranes. Study design: An amniotic fluid index (AFI) was determined before amniocentesis (<24 h) in 272 patients with preterm labor and intact membranes (<35 weeks of gestation). Amniotic fluid (AF) was cultured for aerobic and anaerobic bacteria and genital mycoplasmas, and assayed for matrix metalloproteinase-8 (MMP-8). Non-parametric statistical techniques and survival analysis were used. Results: 1) The overall prevalence of oligohydramnios (AFI of ≤5 cm) in patients with preterm labor and intact membranes was 2.6% (7/272); 2) patients with oligohydramnios had a higher frequency of AF infection and/or inflammation than those without oligohydramnios [85.7% (6/7) vs. 32.8% (87/265); P<0.01]; 3) patients with oligohydramnios had a higher median AF MMP-8 concentration than those without oligohydramnios [median 664.2 (range 16.6–3424.7) ng/mL vs. median 2.3 (range <0.3–6142.6) ng/mL; P<0.01]; 4) women with preterm labor and oligohydramnios had a shorter interval to delivery than those without oligohydramnios [median 18 h (range 0–74 h) vs. median 311 h (range 0–3228 h); P<0.01], and this difference remained significant after adjusting for gestational age and the presence or absence of AF infection/inflammation. Conclusion: Patients with preterm labor and oligohydramnios are at increased risk for impending preterm delivery and intra-amniotic inflammation and, therefore, may benefit from careful surveillance.
Designing the Business Models for Circular Economy—Towards the Conceptual Framework

Switching from the current linear model of economy to a circular one has recently attracted increased attention from major global companies e.g., Google, Unilever, Renault, and policymakers attending the World Economic Forum. The reasons for this are the huge financial, social and environmental benefits. However, the global shift from one model of economy to another also concerns smaller companies on a micro-level. Thus, comprehensive knowledge on designing circular business models is needed to stimulate and foster implementation of the circular economy. Existing business models for the circular economy have limited transferability and there is no comprehensive framework supporting every kind of company in designing a circular business model. This study employs a literature review to identify and classify the circular economy characteristics according to a business model structure. The investigation in the eight sub-domains of research on circular business models was used to redefine the components of the business model canvas in the context of the circular economy. Two new components—the take-back system and adoption factors—have been identified, thereby leading to the conceptualization of an extended framework for the circular business model canvas. Additionally, the triple fit challenge has been recognized as an enabler of the transition towards a circular business model. Some directions for further research have been outlined, as well.
Distributed Algorithms for Consensus and Coordination in the Presence of Packet-Dropping Communication Links - Part I: Statistical Moments Analysis Approach

Abstract : This two-part paper discusses robustification methodologies for linear-iterative distributed algorithms for consensus and coordination problems in multicomponent systems, in which unreliable communication links may drop packets. We consider a setup where communication links between components can be asymmetric (i.e. component j might be able to send information to component i, but not necessarily vice-versa), so that the information exchange between components in the system is in general described by a directed graph that is assumed to be strongly connected. In the absence of communication link failures, each component i maintains two auxiliary variables and updates each of their values to be a linear combination of their corresponding previous values and the corresponding previous values of neighboring components (i.e., components that send information to node i). By appropriately initializing these two (decoupled) iterations, the system components can asymptotically calculate variables of interest in a distributed fashion; in particular, the average of the initial conditions can be calculated as a function that involves the ratio of these two auxiliary variables. The focus of this paper to robustify this double-iteration algorithm against communication link failures. We achieve this by modifying the double-iteration algorithm (by introducing some additional auxiliary variables) and prove that the modified double-iteration converges almost surely to average consensus. In the first part of the paper, we study the first and second moments of the two iterations, and use them to establish convergence, and illustrate the performance of the algorithm with several numerical examples. In the second part, in order to establish the convergence of the algorithm, we use coefficients of ergodicity commonly used in analyzing inhomogeneous Markov chains.
[Intrauterine growth retardation, low birth weight and prematurity in neonates of pregnant women with malaria in Colombia].

INTRODUCTION Association between malaria and pregnancy complications, such as prematurity, intrauterine growth restriction, low birthweight and infant mortality has been reported. These effects have been studied widely in areas hyperendemic for malaria, but studies in low-endemic areas are scarce. The study investigated the relation between gestational malaria and low birthweight and intrauterine growth retardation in neonates of a malarial endemic region in Colombia, between 1993 and 2007. METHODS The pattern of development in 1,716 neonates of women with and without malaria infection during pregnancy was evaluated in a cohort study. A total of 394 infected (27% by P. falciparum and 73% by P. vivax) and 1,322 noninfected pregnant women were followed. RESULTS Exposure to gestational malaria was associated with increased risk of low birth weight (RR = 1.37; 1.03-1.83), short height (RR = 1.52; 1.25-1.85), intrauterine growth retardation (RR = 1.29; 1.0-1.66) and prematurity (RR = 1.68; 1.3-2.17). Prematurity was 77% higher in infants of mothers with malaria by P. falciparum than infants of mothers with malaria by P. vivax (RR = 1.77; 1.2-2.6). CONCLUSIONS Low birth weight and intrauterine growth retardation were associated with malaria during pregnancy. Infection with P. vivax was related with adverse effects on the newborn, similar to that reported for P. falciparum.
Head movements modulate visual responsiveness in the absence of gaze shifts

Visuospatial attention is strongly associated with saccades. Given that gaze shifts are often accomplished by combined eye–head movements, attention may also be coupled to head movements. We showed that simply turning the head without shifting the gaze is sufficient to cause a transient unbalance in responding to a visual stimulus. Manual responses to a stimulus flashed shortly before the onset of a horizontal head movement were faster in congruent trials, when the head moved towards the stimulus, than in incongruent trials, when the head moved away from the stimulus. These effects are similar to those observed for saccades. We take this as evidence for a tight link between visuospatial attention and head movements, even when the gaze does not shift.
Moral judgment and moral conduct in the psychopath.

The relationship between moral conduct and moral judgment was investigated by comparing moral reasoning of a psychopathic sample from a maximum security hospital for the criminal offender with a similar inmate, nonpsychopathic sample, and a group of "normals". Psychopaths obtained significantly higher scores on the Kohlberg scale of moral judgment than either of the other groups, for whom no differences were found. Results suggest the hypothesis that lack of guilt feelings in psychopaths facilitate the achievement of higher levels of moral judgment.
