AbstractPollen dispersal is one of the main ways of gene flow. In the past years, rice pollen dispersal and gene flow have been well studies. However, there is much dispute whether the risk of pollen dispersal and gene flow continuously increases with the source area. A Lagrangian stochastic model was used to simulate the pollen depositions at different distances from different pollen source areas. The field experiments showed a good fit in the pollen depositions. The larger the source area, the more the pollen grains were deposited at each distance, with the pollen dispersal distance increasing accordingly. However, this effect gradually leveled off as the source area increased. In the large-area of pollen source, we found a significantly higher saturation point for the amount of pollen deposition. Once the source area exceeded 1000 × 1000 m2, the pollen deposition no longer increased, even if the source area continued to increase, indicating the “critical source area” of rice pollen dispersal. However, a 100 × 100 m2critical source area for conventional rice and hybrid rice was sufficient, while the critical source area for the sterile line was about 230 × 230 m2.

AbstractNasopharyngeal carcinoma (NPC) is a highly metastatic cancer that is consistently associated with Epstein-Barr virus (EBV) infection. In this study, we identify for the first time a role for monoamine oxidase A (MAOA) in NPC. MAOA is a mitochondrial enzyme that catalyzes oxidative deamination of neurotransmitters and dietary amines. Depending on the cancer type, MAOA can either have a tumour-promoting or tumour-suppressive role. We show that MAOA is down-regulated in primary NPC tissues and its down-regulation enhances the migration of NPC cells. In addition, we found that EBV infection can down-regulate MAOA expression in both pre-malignant and malignant nasopharyngeal epithelial (NPE) cells. We further demonstrate that MAOA is down-regulated as a result of IL-6/IL-6R/STAT3 signalling and epigenetic mechanisms, effects that might be attributed to EBV infection in NPE cells. Taken together, our data point to a central role for EBV in mediating the tumour suppressive effects of MAOA and that loss of MAOA could be an important step in the pathogenesis of NPC.

Published: April 2020

Abstract
Background Atropine is a constitutive alkaloid of belladonna, which is widely used in homeopathic medicine in high dilutions (HDs). In HDs, atropine molecules are not correlated with the energy of electrophysical interactions or the presence of aggregates, resulting in neurotoxic effects. However, in small concentrations at the nanoscale, its effects could present therapeutic advantages.
Objective In the present study, the physicochemical properties of a range of HDs of atropine were analysed to establish a correlation between its electrical and morphological properties.
Methods The electrodynamic properties were analysed with a conductivity meter, whereas the size and morphology of the nanoparticles were evidenced by transmission electron microscopy and atomic force microscopy. The HDs were prepared with deionised water under sterile conditions. Hydrogen potential (pH) and electrical potential were determined with a portable equipment. Electrical conductivity (EC) was calculated using the ionic strength and Debye length.
Results The characterisation of atropine HDs showed the formation of aggregates and the fluctuation of morphological variables at each dilution. Electromagnetic and pH changes were evidenced, which could contribute to a change in the EC. Possibly being responsible for a better response at the cellular level without triggering side effects in the individual.These data suggest that the forces of Derjaguin–Landau–Verwey–Overbeek and the forces of Van der Waals are involved in the variety of forms among these aggregates.The EC was significant at 200°C. This variation suggests changes in the electromagnetic configuration of the HDs. It is only through the conformation of nanoparticle aggregates that these variations can be triggered.
Conclusion Atropine HDs have demonstrated the presence of nanoparticle aggregates with different morphological and electromagnetic properties. Our results may be relevant for future approaches focused on the use of atropine in HDs to minimise cytotoxic effects or modulate adverse effects in patients with neuropathy.Until now, the therapeutic effects of homeopathy have not been relevant to the scientific community; however, here we demonstrate with scientific approaches the conformation of aggregates of nanoparticles present in HDs that modify their structure and electromagnetism, properties that could produce differential biological responses without generating cytotoxicity.

Abstract
Root interactions on sole crop and intercrop give different effects of competition. Understanding on root interactions is very challenging due to the methodology limits in root studies especially when we intercrop between tree and crop components. The objectives of this study were (1) to measure the aboveground and belowground biomass of intercropped Acacia hybrid with Beta vulgaris (red beet) and (2) to determine the rooting pattern at each rhizotron depth. This study involved three (3) types of treatments, Acacia hybrid sole crop, Beta vulgaris sole crop, and intercropping of these two species. Root intensity and root biomass were measured. Root growth of red beet was affected by the presence of Acacia hybrid while Acacia hybrid was not affected for both either in sole or intercrop. However, the root intensity of Acacia hybrid was higher in deeper soil layer when intercrop with red beet. For the root biomass, Acacia hybrid was slightly affected when intercrop with red beet. In contract, red beet was higher when intercrop with Acacia hybrid. In terms of shoot biomass, both crops were not affected when they are in sole or intercrop. The rooting pattern showed that the root length density was dominant in the upper layer for both crops, and intercrop treatment was significantly higher compared to sole crops. In conclusion, Acacia hybrid is the competitor to the red beet in belowground interaction in terms of root growth and rooting pattern. There is no differences in terms of aboveground interactions.

Abstract
Andongrejo Village is one of the buffer villages of Meru Betiri National Park (TNMB). The lack of baseline data related to the diversity of vegetation in agroforestry system surrounding TNMB requires further research as a conservation effort and sustainable ecosystem management purpose. The objectives of this research were to: (a) analyze the structure and composition of vegetation in agroforestry system, (b) analyze the diversity of vegetation in agroforestry system, as well as (c) analyze correlation of canopy density with the diversity of seedlings and understorey in agroforestry system in Andongrejo village, Jember Regency, East Java. The method used was purposive vegetation sampling and vegetation analysis. The number of individual (ind/ha) in all three canopy density classes did not show reverse J-curve. The dominant species found were Banana (Musa sp.), Teak (Tectona grandis), and Sengon (Paraserianthes falcataria). The species richness and diversity index at all tree level growth were clasified into low diversity and low species richness. The higher percentage of canopy density results in the higher individuals per ha and the number of species per ha (r = 0.500 and r = 0.696). The implementation of enrichment planting with species that has high economic value at all tree level growth are necessary. Introducing fruit species is one of alternative ways to increase the local community’s income and conserve the diversity in agroforestry system. Silviculture technique (eg prunning) is necessary to maintain the diversity and tree level growth in this location.

Published: April 2020

AbstractThis study was conducted to determine the species diversity and carbon stock potential of the one-hectare Indigenous Tree Farm at Bohol Island State University-Bilar in the province of Bohol, Philippines. Following its establishment in 2014, trees within the project area have been monitored for species richness and growth rates. Growth rates were calculated using basal diameter, diameter at breast height, and total height. An allometric equation utilizing species presence and growth data was used to calculate projected carbon sequestering potential within the next five years. Forty-four species of trees, including endangered and vulnerable species, were identified within the project site. The species diversity within the site was found to be 2.90 (moderate). There were a total of 1,342 individual trees whose combined carbon load was calculated to be 9.21 tons.

Published: April 2020

Abstract
Clonal forestry of teak in the community forest could increase the forest productivity where the shoot cutting was one of the vegetative propagation methods to propagate and maintain the superior clone of teak. However, the major problem on the shoot cutting of teak was the difference in rooting ability among rooting media, IBA (Indolebutyric Acid) and selected superior of teak clone. The research was conducted on split-split plot design with 10 individual as replication on each treatment. The main plot was two rooting media (cocopeat:rice husk 2:1/A; and soil:sand:compost 3:2:1/B). The subplot was IBA hormone concentration (0 ppm, 50 ppm, 100 ppm, 150 ppm) and the sub-sub plot was 11 clones of teak. The result showed that the rooting ability of teak was affected by all of treatments and interaction among them (P < 0.05), except for the interaction between IBA dosage and clone (P >0.05). The primary and secondary root length showed that clone and interaction between media and clone were significantly different (P < 0.05), while the media was only significantly different for secondary root length (P < 0.05). However, the number of primary and secondary root was not affected by the treatments (P>0.05). Moreover, the best result of rooting ability of teak for rooting media, IBA and was the cocopeat:rice husk (70,53%), IBA 150 ppm (53.18%) and clone WG2 (85%), respectively. It suggested that the seedling production of superior teak through the shoot cutting method depended on the rooting media, IBA concentration, and the specific of teak clone.

Published: April 2020

Abstract
Social welfare and food security become essential issues of forest management in Java. Agroforestry development have a potential to tackle these both issues without sacrifing the forest sustainability. The best agroforestry system should integrate the following three aspects: production, ecological, and social sustainabilities. This study aimed to identify the best agroforestry system that are established in plantation forest area, in Banyumas Forest Management Unit. Four different agroforestry systems were evaluated i.e. Teak, Pine, Cajuput, and Clonal Teak patterns. Each agroforestry system has different intercropping area based on their initial spacing of woody plant. The analytical hierarchy process method and followed by multi criteria analysis were used to determine the best agroforestry system. The proposed indicators of production aspect were timber forest product and non timber forest product. Meanwhile, the defined parameters of ecological aspect were plant biodiversity, microclimate, as well as soil and water conservation. The indicators of social aspect were market network, adoptability, and manageability. The result indicated that the weight for production, ecological, and social sustainabilities aspects were 0.43; 0.14; 0.43, respectively. This study revealed the best agroforestry system that can integrate the balance of production, ecological, and social sustainabilities aspects was Clonal Teak pattern (2.39). The next position was occupied by Teak pattern (2.08) and then followed by Pine pattern (2.06). The Cajuput pattern, however, was the last position (1.15), and therefore it was not recommended for agroforestry system in this area.

Abstract
For the past five decades, the state of private forest in the Gunungkidul district has exhibited an expansion after previously shrinking. This paper aims to provide an in-depth look into the process-dynamics of private forest transitions that occur as well as the pathways and drivers. Using content analysis and semi-structured interview methods this research is conducted in Jepitu Village, District of Gunungkidul. The transition of land use in Gunungkidul can be said as a form of private forest transition. This condition is evidenced by the increase in the area which is identical to the land-use system in the terminology of private forests. The process of private forest transition that took place in Gunungkidul occurred evolutionarily through certain stages. In general, the process of transitioning community forests in Gunungkidul follows three forest transition paths, namely: economic development, forest scarcity, and smallholders, tree-based land-use intensification pathways. Nevertheless, the process of transitioning private forests in Gunungkidul has several distinctive characteristics that require further study through a variety of perspectives.

Authors: Bai Jianyun , Ren Qi , Meng Xinyu , Yin Jiang 
Published: April 2020

Abstract
Because the setting method of back pressure of direct air cooling system is not reasonable, the fluctuation range of back pressure and load change are larger when the unit is peak shaving, which reduces the economic efficiency of the unit. In this paper, based on the optimal back pressure of field data calculation, particle swarm optimization (PSO) is used to optimize the modeling of BP neural network. The results show that, compared with the conventional BP model, the back pressure setting value predicted by the optimized model is more accurate, the model precision is higher, and it is more suitable for industrial field application. This method also provides some reference for the modeling of other objects in the process of thermal production.

Published: April 2020

Abstract
In this paper, the thermal behaviours of phase change material (PCM) within a compact thermal energy storage panel installed with conductive metal fins were numerically investigated. To improve the thermal performance of the metal fins, a topological structure optimization approach was employed to generate innovative fin structures with the so-called best heat conduction paths. The conventional plate fin structures with the same metal volume fractions as the optimized structures were considered for comparative studies. Four metal volume fractions including 0.05, 0.10, 0.15 and 0.20 were investigated. Results showed that at the same metal volume fraction, the optimized fin design can significantly enhance the melting of PCM as compared to the plate fin design. When f=0.9, the average PCM melting speeds obtained by the optimized fin structures were 1.10, 1.19, 1.31, and 1.69 times as that by the plate fin designs at the melt volume fractions of 0.05, 0.10, 0.15 and 0.20, respectively. Moreover, the optimized fin structure with a metal volume fraction of 0.10 can achieve the comparable melting speed as the plate fin design with a metal volume fraction of 0.15, and the melting speed achieved by the optimized fin structure with a metal volume fraction of 0.15 is even faster than that by the plate fin design with a metal volume fraction of 0.20.
Enhancement of thermoelectric performance of YbMg2Bi2-based materials by alloying and doping with suppressed bipolar effect
Authors: Zhou Ting , Jiang Jing , Wang Chao 
Published: April 2020

Abstract
Here we report the enhanced thermoelectric performances of the YbMg2Bi2-based compounds. The formation of Yb0.8-xCaxMg0.2Mg2Bi1.96 (x = 0, 0.2, 0.4, and 0.6) solid solutions effectively decreases the thermal conductivity. Besides, the bandgap of the compounds is widened due to the larger bandgap of CaMg2Bi2 than YbMg2Bi2. Further doping Sn into the Bi site suppresses the bipolar effect and enhances the electrical conductivity at higher temperature by increasing the carrier concentration. And the lattice thermal conductivity is reduced due to the intensified point defects scattering. Benefiting from these results, a higher maximum ZT for Yb0.4Ca0.4Mg0.2Mg2Bi1.95Sn0.01 is achieved. Our work sheds lights on enhancing the thermoelectric performance by suppressing the bipolar conduction and improving the power factor through widening the bandgap accompany by increasing the carrier concentration, and demonstrates that YbMg2Bi2-based Zintls are promising candidates for thermoelectric materials.

Abstract
When the primary air fan of a 300MW circulating fluidized bed boiler is operated at a variable frequency, there is a problem of “against the wind” under the condition that the fan is under low load and the air pressure is low. This paper aims at fixing the aforementioned problem and finding out the cause of the “against the wind” of the primary air fan, and proposing the solutions of adjusting the frequency conversion and the inlet diversion at the same time by analyzing the cold fluidization test, the combination test of the fan adjustment mode, the frequency and speed test of the frequency converter, etc. This method successfully avoids the “Agiainst the wind” situation during low load operation, which is important for the adjustment of low-load down-conversion operation of primary air fan of circulating fluidized bed boiler.

Aiming at the characteristics of time series, non-linearity and small fluctuation of power reactive load data, this paper proposes a reactive power load prediction method based on LSTM (long short-term memory) neural network. The proposed method is used to process and predict the power reactive load data of a certain area in Fujian Province. The experimental results show that the LSTM model with one layer and 64 neuron structures have the best result among the support vector regression (SVR), the random forest model (RF), Recurrent Neuron Network (RNN), LSTM-CNN hybrid neural network, the prediction of reactive load on long-term scale has higher accuracy and stability.
