Research on Neural Machine Translation Model
Authors: Chen Mengyao , Li Yong , Li Runqi 
Published: July 2019

Abstract
In neural machine translation (NMT), cyclic neural networks, especially long-term and short-term memory networks and gated recurrent neural networks, have been regarded as the latest methods for sequence modeling and transduction problems for a long time, such as language modeling and machine translation. When the cyclic neural network is running, the sequence information is processed one by one, strictly following the order from left to right or from right to left, processing one word at a time, and parallel operation cannot be realized, resulting in slow running speed. With the rapid development of neural machine translation (NMT) network architecture, cyclic neural network has been effectively replaced by convolution network and self - attention. Convolution neural network has replaced the divine circulation neural network due to its parallel computation of convolution. The Transformer model replaces the long-term and short-term memory network with a complete self-attention structure, and abandons the traditional encoder and decoder model which must combine the inherent mode of convolutional neural network or circular neural network and only uses the self-attention mechanism. Although the biggest innovation of Transformer architecture is to use full self - attention, there are several other factors, such as multi-head attention and residual connection. The model flexibly combine several common building blocks in the Transformer architecture with the cyclic neural network. By borrowing the framework of the Transformer architecture without using full self - attention, experiments show that the cyclic model can be very close to the performance of the Transformer Our model achieved 26.7 BLEU in the WMT 2014 English to German translation task and 37.8 BLEU in the WMT 2014 English to French translation task. Using these two scores alone is very close to the score of the Transformer architecture using full attention, so even if the cyclic neural network is used instead of full self - attention, it can perform well on the data set.

Authors: Lv Bing , Li Zequn , Chen Mengjia , Wang Jianqiang , Yan Jie 
Published: July 2019

Abstract
In order to accurately predict the future direction of corn cutting platform technology and rapidly develop a new generation of technologies and products, it is crucial to determine the current position of the corn cutting platform technology in the life cycle. Corn cutting platform had problems such as inefficient design, relatively high purchase costs, and short life. After quantitative and qualitative analysis of patents related to corn cutting platform technology, the S-curve law of technical system evolution theory was used to predict that the current corn cutting platform technology is in a recession period in the S-curve. In this period the super-system evolution law should be used in the innovative design of the corn cutting platform. Thereby the design efficiency of the corn header is improved. The causal chain analysis method was used to analyze the reasons for the high cost of the corn cutting platform. It is inferred that the above problems can be solved from the “single corn cutting platform function” and “too long corn cutting platform idle time”. The corn cutting platform that harvests both grain corn and silage corn was derived by applying the technical contradiction method and the super-system evolution rule.

Authors: Li Yana , Wu Xuming 
Published: July 2019

Abstract
The strength of the mounting seat under static strength conditions determines the stability and reliability of the energy-absorbing structure on the metro vehicle. In this paper, five improvement schemes were proposed and the optimal scheme was determined under the worst static strength load condition for the mounting seat of energy-absorbing structure. The results showed that reinforcements had no obvious effect on the stress distribution at the weld seam of the mounting seat. According to the characteristic of transferring deformation and force, the effect of changing the position of the weld seam and moving it away from the stress concentration area was more feasible method.

Published: July 2019

Abstract
In this paper, the expression of polarization structure for superlattice materials with phase mismatch and relative coefficient is established. Based on this method, a MgO:APLN crystal with two reciprocal lattice vectors is designed to generate 1.47μm, 3.84μm and 1.57μm, 3.3μm parametric light pumped by 1064 nm fundamental frequency light. Comparing the Fourier coefficients of MgO:APLN crystals with different structures, it is found that the Fourier coefficients of the two reciprocal lattice vectors are equal when the relative coefficient is 1:1. Based on this crystal, the experiment of external cavity MgO:APLN-MOPO is carried out to optimize the output transmittance of parametric optical coupling. With 20kHz high repetition rate 1064nm laser pumping, 1.57μm and 3.84 μm are achieved and the average power are 4.1W and 3.7W, respectively. The corresponding light-to-light conversion efficiency are 17.1% and 15.4%.

Published: July 2019

Abstract
Oil and gas pipeline deformation detector is of great significance for pipeline deformation detection. In view of the poor throughput of small diameter oil and gas pipelines, this paper presents an internal deformation detection technology based on eddy current effect. Based on the eddy current theory, a mathematical model for eddy current testing of pipeline deformation defects is established. The relationship between probe lift-off value and magnetic field intensity is studied by numerical calculation method. The results show that under the same lift-off value, the composite magnetic field intensity is negatively correlated with the axis distance of the excitation coil, and at the same position, the composite magnetic field intensity is positively correlated with the lift-off value. The research in this paper has certain guiding significance for the internal detection technology of pipeline deformation defect.
Secreted Monocyte miR-27a, via Mesenteric Arterial Mas Receptor-eNOS Pathway, Causes Hypertension
Authors: Zou Xue , Wang Jialiang , Chen Caiyu , Tan Xiaorong , Huang Yu , Jose Pedro A , Yang Jian , Zeng Chunyu 
Published: July 2019

Abstract

BACKGROUND
Essential hypertension is associated with increased plasma concentrations of extracellular vesicles (EVs). We aimed to determine the role of monocyte miR-27a in EVs on arterial Mas receptor expression, and its involvement in the pathogenesis of hypertension.

METHODS
THP-1 cells were transfected with miR-27a mimic and miR-27a inhibitor, and EVs were collected. Mas receptor expression and endothelial nitric oxide synthase (eNOS) phosphorylation were determined by immunoblotting. Sprague–Dawley (SD) rats received EVs via tail-vein injection. Blood pressure (BP) was measured with the tail-cuff method. The vasodilatory response of mesenteric arteries was measured using a small vessel myograph.

RESULTS
EVs from THP-1 cells increased rat BP by impairing Ang-(1–7)-mediated vasodilation in mesenteric arteries, which was further exaggerated by EVs from lipopolysaccharides-treated THP-1 cells. As the receptor and key signaling of Ang-(1–7), next experiments found that Mas receptor expression and eNOS phosphorylation were decreased in mesenteric arteries from EVs-treated SD rats. Screening studies found miR-27a in EVs may be involved in this process. Through transfection with miR-27a inhibitor or miR-27a mimic, we found that miR-27a downregulates Mas receptor expression in endothelial cells. Injection of EVs from miR-27a-transfected HEK-293 cells decreased Mas receptor and eNOS phosphorylation in mesenteric arteries, impaired Ang-(1–7)-mediated vasodilation and increased BP. Earlier effects were reversed using cells with downregulation of miR-27 in EVs.

CONCLUSIONS
Monocyte miR-27a in EVs decreases Mas receptor expression and eNOS phosphorylation in endothelium, impairs Ang-(1–7)-mediated vasodilation, and causes hypertension. Understanding the contributions of EVs in the pathogenesis of hypertension may facilitate their use as a diagnostic biomarker.
Species interactions modulate the response of saltmarsh plants to flooding
Authors: Edge Ryan S , Sullivan Martin J P , Pedley Scott M , Mossman Hannah L 
Published: July 2019

Abstract

Background and Aims
The vegetation that grows on coastal wetlands is important for ecosystem functioning, a role mediated by plant traits. These traits can be affected by environmental stressors and by the competitive environment the plant experiences. The relative importance of these influences on different traits is poorly understood and, despite theoretical expectations for how factors may interact, empirical data are conflicting. Our aims are to determine the effect of flooding, species composition and their interaction on plant functional traits, and assess the role of biodiversity and species composition in driving community-level responses to flooding.

Methods
We conducted a factorial glasshouse experiment assessing the effects of species composition (all combinations of three saltmarsh species, Aster tripolium, Plantago maritima and Triglochin maritima) and flooding (immersion of roots) on a suite of functional traits. We also related biomass in mixed species pots to that expected from monocultures to assess how species interactions affect community-level biomass.

Key Results
Species composition frequently interacted with flooding to influence functional traits and community-level properties. However, there was also considerable intraspecific variability in traits within each treatment. Generally, effects of flooding were more pronounced for below-ground than above-ground biomass, while composition affected above-ground biomass more than below-ground biomass. We found both negative and positive interactions between species (indicated by differences in above- and below-ground biomass from expectations under monoculture), meaning that composition was an important determinate of community function.

Conclusions
While the effect of flooding alone on traits was relatively weak, it interacted with species composition to modify the response of both individual plants and communities. Our results suggest that responses to increased flooding will be complex and depend on neighbourhood species interactions. Furthermore, intraspecific trait variability is a potential resource that may dampen the effects of changes in flooding regime.
Herbivory may promote a non-native plant invasion at low but not high latitudes
Authors: Lu Xinmin , He Minyan , Tang Saichun , Wu Yuqing , Shao Xu , Wei Hui , Siemann Evan , Ding Jianqing 
Published: July 2019

Abstract

Background and Aims
The strengths of biotic interactions such as herbivory are expected to decrease with increasing latitude for native species. To what extent this applies to invasive species and what the consequences of this variation are for competition among native and invasive species remain unexplored. Here, herbivore impacts on the invasive plant Alternanthera philoxeroides and its competition with the native congener A. sessilis were estimated across latitudes in China.

Methods
An common garden experiment spanning ten latitudinal degrees was conducted to test how herbivore impacts on A. philoxeroides and A. sessilis, and competition between them change with latitude. In addition, a field survey was conducted from 21°N to 36.8°N to test whether A. philoxeroides invasiveness changes with latitude in nature as a result of variations in herbivory.

Key Results
In the experiment, A. sessilis cover was significantly higher than A. philoxeroides cover when they competed in the absence of herbivores, but otherwise their cover was comparable at low latitude. However, A. philoxeroides cover was always higher on average than A. sessilis cover at middle latitude. At high latitude, only A. sessilis emerged in the second year. Herbivore abundance decreased with latitude and A. philoxeroides emerged earlier than A. sessilis at middle latitude. In the field survey, the ratio of A. philoxeroides to A. sessilis cover was hump shaped with latitude.

Conclusion
These results indicate that herbivory may promote A. philoxeroides invasion only at low latitude by altering the outcome of competition in favour of the invader and point to the importance of other factors, such as earlier emergence, in A. philoxeroides invasion at higher latitudes. These results suggest that the key factors promoting plant invasions might change with latitude, highlighting the importance of teasing apart the roles of multiple factors in plant invasions within a biogeographic framework.
CHA2DS2-VASc Stroke Risk Index and Executive Functioning in Older Adults
Authors: Duda Bryant M , Keith Cierra M , Sweet Lawrence H 
Published: July 2019

AbstractObjectiveCHA2DS2-VASc is a stroke risk classification system developed to improve the precision of stroke risk classification. The current study examined the validity of CHA2DS2-VASc in a sample of healthy older adults using executive function measures of processing speed, working memory, and cognitive flexibility that are sensitive to cerebrovascular risk factors.MethodsParticipants included 51 community-dwelling, healthy older adults (ages 53–86) recruited from both the community and cardiology clinics. CHA2DS2-VASc was utilized as a measure of stroke risk. Measures of executive functioning and processing speed included the Paced Auditory Serial Addition Test (PASAT), Delis–Kaplan Executive Function System (DKEFS) Number–Letter Switching, and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Coding.ResultsCHA2DS2-VASc scores significantly predicted scores on the PASAT, DKEFS Number-Letter Switching, and RBANS Coding, such that greater stroke risk was associated with poorer performances on tests of executive functioning and processing speed. These relationships were observed over and above the potential influence of educational attainment and symptoms of depression.ConclusionSignificant relations between stroke risk classification and performance on several measures of executive functioning provide support for a wider and more generalized use of CHA2DS2-VASc with healthy older adults. These findings further highlight the importance of early identification and treatment of stroke risk factors associated with cognitive decline. Findings suggest that CHA2DS2-VASc is a practical and useful tool for patients and their providers in the early detection of stroke risk and development of individualized treatment plans.
Pair bonds, reproductive success, and rise of alternate mating strategies in a social carnivore
Authors: Ausband David E 
Published: July 2019

Abstract
Monogamy is commonly observed across a wide variety of species and taxa and arises when young are altricial, parental investment in young is high, and mate monopolization is generally not possible. In such species, pairs may bond for multiple breeding seasons while successfully rearing young. Individuals, however, may attempt to bypass the dominant mating strategy particularly when breeding opportunities are limited. Currently, we do not know how pair bond duration affects the efficacy of alternative mating strategies in populations with a monogamous mating system. Additionally, inferences about pair bond effects on reproductive success (i.e., both clutch size and recruitment) are largely limited to long-lived birds and little is known about effects on mammalian cooperative breeders. I used genetic sampling and pedigrees to examine the effects of pair bond duration on reproductive success (i.e., litter size, recruitment) and mating strategies in a population of gray wolves (Canis lupus) in Idaho, USA. There was a positive, marginally significant relationship between pair bond duration and apparent survival of offspring. Increased pair bond duration was also associated with a dampening in the prevalence of other alternative mating strategies such as sneaker males and polygamy. The selective advantage of alternative mating strategies is a combination of population, group (for applicable species), individual, and social influences such as pair bonds. The distribution of pair bonds in a monogamous population affects the selective advantage, and hence frequency, of various mating strategies observed.
Auxin-inducible protein degradation as a novel approach for protein depletion and reverse genetic discoveries in mammalian oocytes†
Authors: Camlin Nicole J , Evans Janice P 
Published: July 2019

Abstract
The disruption of protein expression is a major approach used for investigating protein function in mammalian oocytes. This is often achieved with RNAi/morpholino-mediated knockdown or gene knockout, leading to long-term loss of proteins of interest. However, these methods have noteworthy limitations, including (a) slow protein turnover can prohibit use of these approaches; (b) essential roles in early events precludes characterization of functions in subsequent events; (c) extended protein loss can allow time for compensatory mechanisms and other unanticipated events that confound interpretation of results. The work presented here examines the use of auxin-inducible degradation, a powerful new approach that overcomes these limitations through the depletion of one's protein of interest through controllable ubiquitin-mediated degradation. This method has been employed in yeast and mammalian cell lines, and here we demonstrate the utility of auxin-inducible degradation in mouse oocytes at multiple stages of meiosis, through degradation of exogenously expressed EGFP. We also evaluate important parameters for experimental design for use of this system in oocytes. This study thus expands the toolkit of researchers in oocyte biology, establishing the use of this unique and versatile approach for depleting proteins in oocytes, and providing researchers with valuable information to make use of this system.

Was Keynes a socialist?
Authors: Fuller Edward W 
Published: July 2019

AbstractThis paper addresses the controversy over Keynes’s political thought. Robert Skidelsky portrays Keynes as a liberal who wanted to save capitalism. By contrast, Rod O’Donnell argues Keynes was a socialist. This paper presents unexplored evidence that shows Keynes was a non-Marxist socialist from 1907 until his death in 1946. First, the paper demonstrates that Keynes described himself as a socialist and aligned himself with socialism. Next, the paper shows Keynes can be defined as a socialist because he advocated socialist policy. Finally, the paper discusses Keynes’s socialist political and journalistic activities. Keynes was a non-Marxist socialist, meaning Skidelsky has misinterpreted Keynes’s political philosophy.
