AbstractThe vasopressin 1b receptor (Avpr1b) plays an important role in social behaviors including aggression, social learning and memory. Genetic removal of Avpr1b from mouse models results in deficits in aggression and short-term social recognition in adults. Avpr1b gene expression is highly enriched in the pyramidal neurons of the hippocampal cornu ammonis 2 (CA2) region. Activity of the hippocampal CA2 has been shown to be required for normal short-term social recognition and aggressive behaviors. Vasopressin acts to enhance synaptic responses of CA2 neurons through a NMDA-receptor dependent mechanism. Genetic removal of the obligatory subunit of the NMDA receptor (Grin1) within distinct hippocampal regions impairs non-social learning and memory. However, the question of a direct role for NMDA receptor activity in Avpr1b neurons to modulate social behavior remains unclear. To answer this question, we first created a novel transgenic mouse line with Cre recombinase knocked into the Avpr1b coding region to genetically target Avpr1b neurons. We confirmed this line has dense Cre expression throughout the dorsal and ventral CA2 regions of the hippocampus, along with scattered expression within the caudate-putamen and olfactory bulb. Conditional removal of the NMDA receptor was achieved by crossing our line to an available floxed Grin1 line. The resulting mice were measured on a battery of social and memory behavioral tests. Surprisingly, we did not observe any differences between Avpr1b-Grin1 knockout mice and their wildtype siblings. We conclude that mice without typical NMDA receptor function in Avpr1b neurons can develop normal aggression as well as short-term social and object memory performance.Significance StatementActivity of neurons that express vasopressin 1b receptor are essential for aggressive and social recognition behaviors. We created a novel transgenic mouse to allow selective targeting of vasopressin 1b neurons. Our studies indicate that NMDA receptor expression in vasopressin 1b neurons (including most CA2 neurons) are not required for development of the typical expression of aggression or recognition memory. Thus, CA2 neurons may have a unique way of incorporating novel stimuli into memory that deserves further investigation.

AbstractTAZ promotes cell proliferation, development, and tumorigenesis by regulating target gene transcription. However, how TAZ orchestrates the transcriptional responses remains poorly defined. Here we demonstrate that TAZ forms nuclear condensates via liquid-liquid phase separation to compartmentalize its DNA binding co-factor TEAD4, the transcription co-activators BRD4 and MED1 and the transcription elongation factor CDK9 for activation of gene expression. TAZ, but not its paralog YAP, forms phase-separated droplets in vitro and liquid-like nuclear condensates in vivo, and this ability is negatively regulated by Hippo signaling via LATS-mediated phosphorylation and mediated by the coiled-coil domain. Deletion of the TAZ coiled-coil domain or substitution with the YAP coiled-coil domain does not affect the interaction of TAZ with its partners, but prevents its phase separation and more importantly, its ability to induce target gene expression. Thus, our study identifies a novel mechanism for the transcriptional activation by TAZ and demonstrates for the first time that pathway-specific transcription factors also engage the phase separation mechanism for efficient transcription activation.

1.AbstractTying the hands behind the back has detrimental effect of sensorimotor perceptual tasks. Here we provide evidence that beta band oscillatory activity in a resting state condition might have a crucial role in such detrimental effects. EEG activity in a resting state condition was measured from thirty participants in two different body posture conditions. In one condition participants were required to keep their hands freely resting on the table. In the other condition, participants were required to keep the hands tied behind their back. Increased beta power was observed in the left inferior frontal gyrus (l-IFG) during the tied hands condition compared to the free hands condition. A control study ruled out alternative explanations including muscle tension that might have affected the EEG data. Our findings provide new insight on how body postural manipulations impact on perceptual tasks and intrinsic brain activity.

Published: June 2019

The first silver bismuth borate, AgBi2B5O11(silver dibismuth pentaborate), has been preparedviaglass crystallization in the Ag2O–Bi2O3–B2O3system and characterized by single-crystal X-ray diffraction. Its structure is derived from that of centrosymmetric Bi3B5O12by ordered substitution of one Bi3+ion for Ag+, which results in the disappearance of the mirror plane and inversion centre. Second harmonic generation (SHG) measurements confirm the acentric crystal structure. It is formed by [Bi2B5O11]∞layers stretched alongcand comprised of vertex-sharing B5O10and BiO3groups which incorporate the Ag+cations. The new compound was characterized by thermal analysis, high-temperature powder X-ray diffraction, and vibrational and UV–Vis–NIR (near infrared) spectroscopy. Its thermal expansion is strongly anisotropic due to the presence of rigid B5O10groups aligned in a parallel manner. The minimal value is observed along their axis [parallel toc, αc = 3.1 (1) × 10−6K−1], while maximal values are observed in theabplane [αa= 20.4 (2) and αb= 7.8 (2) × 10−6K−1]. Upon heating, AgBi2B5O11starts to decay above 684 K due to partial reduction of silver; incongruent melting is observed at 861 K. According to density functional theory (DFT) band-structure calculations, the new compound is a semiconductor with an indirect energy gap of 3.57 eV, which agrees with the experimental data (absorption onset at 380 nm).

Purpose
The purpose of this paper is to provide a linguistic perspective for corporate brochures. Corporate brochures are published to introduce an organization and to provide information about it but the brochures have been claimed to include promotional elements. By conducting a genre analysis the paper aims to confirm that genre-based writing is not formulaic but instead demonstrates versatility and creativity.

Design/methodology/approach
Corporate brochures from a specific industry, oil and gas were sourced from the websites and a total of 16 were available. The method of analysis was genre analysis to establish the generic structure of the brochures by examining the rhetorical moves and strategies, and to identify the textual features of the texts to explain why they are written the way they are.

Findings
The oil and gas brochures display a five-move generic structure with a number of strategies. The moves show high occurrence proving the industry as a specialized one. Although the moves are the same, the contents are varied. Versatility is also seen in the presentation style in terms of form, content and language.

Practical implications
Findings on generic structure and textual features of brochures can be used as a guide for corporate writers, as well as trainees and students of corporate communication.

Originality/value
The data for this research represent one industry which has not been explored before thus contributing to the body of knowledge in the field of genre analysis. Although generic in form, genre-based writing has proven to be versatile. The textual features show how companies project their corporate image via brochures.

Creating a reliable financing mechanism for economic development
Authors: Li Yang 
Published: June 2019

Purpose
China’s economic development in the past 40 years has an array of distinctive features that have attracted the attention of the world. The paper aims to discuss this issue.

Design/methodology/approach
The analysis logic is as follows: with regard to the mechanism, the above factors were met in a timely manner and jointly contributed positive energy to China’s economic growth, with the increase in the savings rate as the necessary condition and foundation, and the increase in the savings rate is attributed to the explosive expansion of the financial system at the beginning of reform and the formation of positive incentives for residents, enterprises and governments at all levels, and the expansion of the financial system and the formation of positive incentives are clearly the crystallization of the wisdom of Chinese-style progressive reform.

Findings
Therefore, we have every reason to believe that the growth prospects of the Chinese economy remain bright. The author is nonetheless confident that the new two-step strategy for economic development will be realized, proposed by the 19th CPC National Congress.

Originality/value
Moreover, the growth of China’s economy has long been accompanied by the “double surplus” of current accounts and capital and financial accounts in the international balance of payments, which is not completely consistent with the traditional paradigm of development economics. These phenomena are so unique that the international community calls it the “Mystery of China” or “China’s Development Path.”

Authors: Long Xiaoning 
Published: June 2019

Purpose
Innovation is the fundamental driving force for the long-term sustainable development of an economy. After four decades of rapid economic growth, China is facing crises related to a demographic structure of “aging before getting rich,” industrial overcapacity of low-end products and environmental and resources constraints. This paper aims to discuss these issues.

Design/methodology/approach
Based on logical analysis and recapitulation of previous empirical research, this study presents the conclusion.

Findings
Scientific and technological innovation, as strategic support to improve social productivity and overall national strength, must be placed at the center of the country’s overall development.

Originality/value
The development model that preys upon cheap resources for extensive growth is unsustainable. Thus, the country needs an urgent strategic switch to drive its economic growth through research and development innovation and original technological advancement.

Application of biharmonic equation in impeller profile optimization design of an aero-centrifugal pump
Authors: Liu Xianwei , Li Huacong , Shi Xinxing , Fu Jiangfeng 
Published: June 2019

Purpose
The purpose of this paper is to improve the hydraulic efficiency without changing the overall dimension. The blade profile optimization design of the aero-centrifugal pump based on the biharmonic equation surrogate model has been studied.

Design/methodology/approach
First of all, Bezier curves and linear function are used to control the annular angle distribution and the stacking angle of blade profile under the MATLAB platform. Grid independence analysis has been studied to find the finest mesh scheme. After the precision comparison of test data and computation fluid dynamics 15 sets of design parameters are carried out as the boundary condition of the biharmonic equation. The efficiency surrogate model of the biharmonic equation is constructed via iteratively solving of a discrete difference equation. The other two surrogate models of response surface model (RSM) and radial basis function neural network surrogate model (RBFNNSM) are compared with the biharmonic equation surrogate model by the standard of modified complex correlation coefficient R2 and root mean square deviation (RSME). Finally, the artificial fish swarm algorithm has been used to find the global optimal design parameters with the objective function of highest efficiency.

Findings
The results show that the design parameters code conversion method can reduce the number of optimization parameters from five to three, makes the design space become a cube, and compared with RSM and RBFNNSM, the biharmonic equation surrogate model has higher precision with R2 is 0.8958, RSME is 0.1382. The final optimum result of AFSA is at the point of [1 −1 −1]. The internal flow field analysis shows that after optimization the outlet relative velocity becomes more uniform and the wake effect has been significantly decreased. The hydraulic efficiency of the optimized pump is about 59.45 per cent increasing 5.4 per cent compared with a prototype pump.

Originality/value
This study developed a new method to optimize the design parameters of aero-centrifugal pump impeller based on biharmonic equation surrogate model, which had a good agreement with experimental values within just 15 sets of the original design. The optimization results shows that the method can improve the hydraulic efficiency significantly.
An adaptive order response surface method for structural reliability analysis
Authors: Zhang Wentong , Xiao Yiqing 
Published: June 2019

Purpose
Balancing accuracy and efficiency is an important evaluation index of response surface method. The purpose of this paper is to propose an adaptive order response surface method (AORSM) based on univariate decomposition model (UDM).

Design/methodology/approach
First, the nonlinearity of the univariate function can be judged by evaluating the goodness of fit and the error of curve fit rationally. Second, combining UDM with the order analysis of separate component polynomial, an easy-to-implement AORSM is proposed. Finally, several examples involving mathematical functions and structural engineering problems are studied in detail.

Findings
With the proposed AORSM, the orders of component functions in the original response surface can be determined adaptively and the results of those cases in this paper indicate that the proposed method performs good accuracy, efficiency and robustness.

Research limitations/implications
Because just the cases with single failure mode and single MPP are studied in this paper, the application in multi-failure mode and multi-MPP cases need to be investigated in the coming work.

Originality/value
The nonlinearity of the univariate in the response surface can be determined adaptively and the undetermined coefficients of each component function are obtained separately, which reduces the computation dramatically.
Developing a maintenance index framework for heritage concrete buildings
Authors: Ismail Zul-Atfi 
Published: June 2019

Purpose
The improper management of conventional systems for recording, diagnosing and analysing information appears to be a major problem in the maintenance of heritage buildings. This is because of a lack of detection of patent or latent defects, ineffective repair methods and inappropriate planning decisions, which increase the risks of failure throughout the lifetime of heritage buildings. The paper aims to discuss this issue.

Design/methodology/approach
The concept of maintenance management practices, as well as techniques and tools from information and communication technology, was reviewed to identify suitable processes and construct an information database of maintenance and management techniques. A maintenance index framework was then formulated by analysing these concepts.

Findings
The initial findings identify the need for decision-making support in the diagnosis of heritage building maintenance based on robust data collection. This should include the selection of a durable replacement design and material or an appropriate rehabilitation method for managing quality and reducing associated defects.

Originality/value
Further research into the maintenance of heritage buildings should consider various aspects in terms of sustainability. The paper concludes that implementing a maintenance index framework can help improve the decision-making performance with regard to the design, construction and maintenance operations of heritage concrete buildings.

Published: June 2019

PurposeThis study aims to present the climate change effect on soil moisture regimes in Mexico in a global 1.5°C warming scenario.Design/methodology/approachThe soil moisture regimes were determined using the Newhall simulation model with the database of mean monthly precipitation and temperature at a scale of 1: 250,000 for the current scenario and with the climate change scenarios associated with a mean global temperature increase of 1.5°C, considering two Representative Concentration Pathways, 4.5 and 8.5 W/m2and three general models of atmospheric circulation, namely, GFDL, HADGEM and MPI. The different vegetation types of the country were related to the soil moisture regimes for current conditions and for climate change.FindingsAccording to the HADGEM and MPI models, almost the entire country is predicted to undergo a considerable increase in soil moisture deficit, and part of the areas of each moisture regime will shift to the next drier regime. The GFDL model also predicts this trend but at smaller proportions.Originality/valueThe changes in soil moisture at the regional scale that reveal the impacts of climate change and indicate where these changes will occur are important elements of the knowledge concerning the vulnerability of soils to climate change. New cartography is available in Mexico.
