Transcriptional reprogramming of the bud-mutation loquat YongLu emerging freezing resistant

Background: Freezing seriously affects loquat, an originally subtropical fruit. Here, a wide-spread cultivar loquat bud mutation ‘Yonglu’ (YL) was found to be more resistant to freezing than the parental ‘Ruantiaobaisha’ (RT), especially the fruits. The freezing resistance mechanism of YL was analyzed by physiological and transcriptomic methods. Results: After freezing treatment, only the fruits of YL showed a significant accumulation of proline (which increased by 1.5-fold). Interestingly, abscisic acid (ABA) accumulation in YL showed no difference after freezing treatment. Moreover, the stomatal density, area, and apertures of YL significantly decreased. All these results suggested that the proline content and stomatal closure contributed to the enhanced freezing tolerance. Further, the transcriptional profiles of freezing tissues were obtained and compared. Functional enrichment analysis showed that aside from basic nutrients and energy metabolisms, such as citrate cycle and oxidative phosphorylation, the fruits and flowers of YL have different systems to enhance freezing tolerance, suggesting a progressive freezing-resistant network. Signaling transduction of nearly all hormones, including ABA, was significantly differentially expressed. Several key genes, such as PP2C and SnRK2, which are crucial for transducing ABA signals, were significantly down- and upregulated, respectively. But the genes of neither ABA biosynthesis nor ABA transduction pathway significantly differentially expressed between two freezing varieties, suggesting they contribute limit in enhancing freezing tolerance of YL. Conclusion: Concludingly, the bud mutation YL loquat has stronger freezing tolerance than its parental RT due to the increasing proline and more effective regulation of stomatal closure. Furthermore, the bud mutation YL loquat reprogrammed its entire transcriptional profiles to enhance their abilities to adapt to freezing stress. However, ABA biosynthesis, ABA transduction pathway and CBF pathway, which are common reasons in cold response, were not the main reason for the increasing freezing tolerance of YL. There must be unknown regulation mechanisms for the bud mutation to freezing resistant.
Enhancement of gamma oscillations in E/I neural networks by increase of difference between external inputs

Experimental observations suggest that gamma oscillations are enhanced by the increase of the difference between the components of external stimuli. To explain these experimental observations, we firstly construct a small excitatory/inhibitory (E/I) neural network of IAF neurons with external current input to E-neuron population differing from that to I-neuron population. Simulation results show that the greater the difference between the external inputs to excitatory and inhibitory neurons, the stronger gamma oscillations in the small E/I neural network. Furthermore, we construct a large-scale complicated neural network with multi-layer columns to explore gamma oscillations regulated by external stimuli which are simulated by using a novel CUDA-based algorithm. It is further found that gamma oscillations can be caused and enhanced by the difference between the external inputs in a large-scale neural network with a complicated structure. These results are consistent with the existing experimental findings well.

CFD SIMULATION OF EROSION BY PARTICLE COLLISION IN U-BEND AND HELICAL TYPE PIPES

Erosion caused by solid particles in curve pipes is one of the major concerns in the oil and gas industries. Small solid particles flow with a carrier liquid fluid and impact the inner wall of the piping, valves, and other equipment. These components face a high risk of solid particle erosion due to the constant collision, which may result in equipment malfunctioning and even failure. In this study, the two-way coupled Eulerian-Lagrangian method with the Oka erosion and Grant and Tabakoff particle-wall rebound models approach is employed to simulate the liquid-solid flow in U-bend and helical pipes using computational fluid dynamics. The effects of operating parameters (inlet fluid velocity and temperature, particle density and diameter, and mass flow rate) and design parameters (mean curvature radius/pipe diameter ratio) are investigated on the erosion of these tubes walls. It is obtained that increasing the fluid velocity and temperature, particle mass flow and particle density increase the penetration rate, particle diameter affects the rate of penetration, and increasing mean curvature radius/pipe diameter ratio decreases the rate of penetration.
Securing Massive MIMO Systems: Secrecy for Free With Low-Complexity Architectures

Passively overheard massive multiple-input multiple-output (MIMO) settings are capable of suppressing eavesdroppers via narrow beamforming towards legitimate receivers. This implies that secrecy is obtained almost for free in these settings. This study shows that this is a valid property for a large class of low-complexity massive MIMO transmitters. The investigations consider two dominant approaches for complexity reduction, namely antenna selection and hybrid analog-digital precoding. It is shown that using either approach, the information leakage per achievable sum-rate vanishes as the number of transmit antennas grows large. The results demonstrate that, as the transmit array size grows large, the normalized information leakage obtained by antenna selection and hybrid analog-digital precoding converges to zero double-logarithmically and logarithmically, respectively. The analytical results are confirmed for various benchmark architectures via numerical simulations.
Negative self-beliefs mediate the relationship between depression and suicide ideation among the elderly population: a cross-sectional study

Background High suicide risk among the aged population is a growing concern. Research has linked depression symptoms to suicidal ideation in the general population. The present study examines whether negative self-beliefs mediate the cross-sectional association between depression symptoms and suicide ideation. Methods A sample of 67 elderly participants from nursing homes, ranging in age from 62 to 91 years ( M = 80.00, SD = 6.67 years; three participants did not indicate the age), completed the Negative Self Belief Inventory, the Geriatric Suicide Ideation Scale, and the 7-item depression subscale of the Depression Anxiety Stress Scale. Results The results show that the associations between depression symptom, negative self-beliefs and suicide ideation were positive ( r = .44 - .52, p < .001). Depression symptoms contributed another 13.70% explained variances. It independently explained another 5.7% variances beyond other variables to suicide ideation after the entering of negative self-belief ( B = 0.126, t = 2.183, p < .05). The indirect effect of depression symptoms on suicide ideation through negative self-belief was significant (Effect = 0.223, 95% BCa CI = [0.034, 0.468]). Conclusion Depression predicts suicide ideation via negative self -beliefs. The current study, incorporated theoretical assumptions and empirical findings in the context of Chinese culture into western prevalent suicide theories. Treatments focusing on restructuring negative self-beliefs are promising to reduce suicide in older adults in China. Future studies should test whether the mechanism in our study can transcend national and cultural boundaries.

Interactions of time delay and spatial diffusion induce the periodic oscillation of the vegetation system

Empirical data exhibit a common phenomenon that vegetation biomass fluctuates periodically over time in ecosystem, but the corresponding internal driving mechanism is still unclear. Simultaneously, considering that the conversion of soil water absorbed by roots of the vegetation into vegetation biomass needs a period time, we thus introduce the conversion time into Klausmeier model, then a spatiotemporal vegetation model with time delay is established. Through theoretical analysis, we not only give the occurence conditions of stability switches for system without and with diffusion at the vegetation-existence equilibrium, but also derive the existence conditions of saddle-node-Hopf bifurcation of non-spatial system and Hopf bifurcation of spatial system at the coincidence equilibrium. Our results reveal that the conversion delay induces the interaction between the vegetation and soil water in the form of periodic oscillation when conversion delay increases to the critical value. By comparing the results of system without and with diffusion, we find that the critical value decreases with the increases of spatial diffusion factors, which is more conducive to emergence of periodic oscillation phenomenon, while spatial diffusion factors have no effects on the amplitude of periodic oscillation. These results provide a theoretical basis for understanding the spatiotemporal evolution behaviors of vegetation system.
FAMILY FACTORS OF AUTONOMY DEVELOPMENT AND SEPARATION PROCESSES IN ADOLESCENCE

Relevance. Adolescence is an important stage in human life. It offers a lot of possibilities for personal development, but it also presents serious challenges, such as development of autonomy, the search for individuality. Parent-child relationships are generally considered a factor of the development of adolescent’s autonomy. Family psychology identifies adolescence as basis for a separate stage in the family life cycle. In this regard, it seems important to investigate the processes of separation and development of the autonomy of adolescents not only in parent-child relations, but in a wider family context. Objective. The goal of the research is to study the family factors of autonomy and separation processes development in adolescence. Method and participants. 51 adolescents in age from 13 to 18 years took part in the study. The following methods were used: questionnaires on autonomy and separation processes, family and child-parent relations, “Family Sociogram”, the incomplete sentences method. Main results. The main content of the ideas about independence and autonomy in adolescents is shown: adolescents determine their autonomy primarily through the behavioral aspect and alienation. Emotional differentiation goes difficult, and adolescents are often susceptible to emotional influence in relationships with significant people. Fear of losing sovereignty is negatively associated with family cohesion, expressiveness, and independence of family members. Neurotic denial of dependence on others is negatively associated with family cohesion, independence of family members, and transparency of family rules. Lack of acceptance of the adolescent, excessive emotional distancing and lack of consent and cooperation in the family is negatively connected with autonomy development and separation of adolescents. Conclusions. It is necessary to consider the development of autonomy and separation processes in adolescence in the context of family relations. Negative family factors are connected with separation difficulties and lack of autonomy in adolescence.
A Semi-Distributed Approach for Uplink Max-Min Energy Efﬁciency Optimization with Minimum User Satisfaction and Adjacency Constraints

—Maximizing energy efﬁciency is one of the pillars of modern networks. In this context, we consider in this letter a nonlinear max-min energy efﬁciency problem in the uplink of wireless networks. Due to the problem nonlinearity we resort to epigraph form so as to obtain an integer linear problem and to propose a centralized optimal solution for it using a branch-and-bound algorithm. Also because distributed solutions are useful to deal with high computational processing and scalability problems, we propose a low-complexity semi-distributed solution for the problem using a speciﬁc signaling scheme. Simulations show that the proposed semi-distributed solution performs closely to the centralized optimal scheme and outperforms state-of-the-art algorithms in terms of energy efﬁciency and outage rate.
Tunable Fano Resonance in E-Shape Plasmonic Nanocavities

The optical properties of e-shape plasmonic nanocavities have been studied. Due to the destructive interference of the quadrupole resonance of the c-shape nanoring with the overlapping dipolar resonance of the nanorod, a tunable Fano resonance within a wide range of spectra from visible light to mid-infrared (mid-IR) spectrum have been observed. The spectral positions and modulation depths of the Fano resonances can be tuned with different geometry parameters of nanocavities, and the performance (modulation depth of spectra and near-field enhancement) of e-shape plasmonic nanocavities can be further improved by optimization of the nanocavity’ radiation characteristics using a dielectric layer (SiO2). Furthermore, capacitive coupling between c-shape nanoring and nanorod antenna was found to be asymmetric, in which Fano resonance can be modulated to symmetric/antisymmetric quadrupole–dipole by moving the nanorod in the positive/negative direction of the x axis. This work opens up new opportunities for engin.

*Corresponding author https://doi.org/10.1590/1679-78256120 Abstract The current paper implementates a simple fully non-linear Kirchhoff-lovel shell penalty based finite element. The 6 nodes and 21 DoF triangular element developed in this work has a quadratic displacement field associated to it and the C 1 continuity required by Kirchhoff-Love Hyphotesis is approximated by an internal penalty. The biggest novelty in this article is the simultaneous use of penalty and a Rodrigues incremental Rotation parameter (scalar DOF) between neighboring elements further explained in the text. The nonlinear finite element model developed in this article is compared to analytical results, commercial finite element code and another FEM model developed in bibliography. Simulations have demonstrated consistency when comparing results to other models and it is deemed that reliable mesh generation together with a powerfull triangular finite element is a good option for trustworthy Love shell,

Fabrication and study of NiPc thin film based surface type photocapacitors

In this paper, the study of nickel phthalocyanine (NiPc) as an active material in photocapacitive detectors is reported. The NiPc thin film based Al/NiPc/Al and Ag/NiPc/Ag surface type photocapacitive detectors were fabricated. The devices were prepared by thermal evaporation of NiPc films of different thicknesses on thoroughly cleaned glass substrates with preliminary deposited metallic electrodes. It was observed that photocapacitance of the samples increases with increase in thickness of the NiPc film and illumination as well. Under filament lamp illumination, the relative capacitance of the sample having aluminum electrodes was greater than the silver one. The photocapacitive response of the detectors is associated with polarization, due to the transfer of photo-generated electrons and holes. The equivalent circuit of the photocapacitive detectors is proposed. Data obtained by simulation showed reasonable agreement with the experimental results.
The temperature sensitive hybrid breakdown 1 induces low temperature-dependent intrasubspecific hybrid breakdown in rice

Hybrid breakdown (HB) is an important type of post-zygotic reproductive barrier that inhibits hybrid production during the process of cross-breeding. A novel low temperature-dependent HB was identified in a chromosomal segment substitution line (CSSL) library derived from a cross of two rice (Oryza sativa L. japonica) cultivars, Yukihikari and Kirara397. A set of weakness symptoms in a target CSSL was observed at 23°C, but was rescued at 27°C and/or 30°C. Genetic analysis of HB using an F2:3 population of a cross between a target CSSL and Kirara397 found that a recessive temperature sensitive hybrid breakdown1 (thb1) gene from Yukihikari caused HB in the genetic background of Kirara397. Molecular mapping showed that thb1 was located within a 199-kb fragment on chromosome 6. A genetic study of F2 populations of reciprocal crosses between Yukihikari and Kirara397 confirmed that this HB was induced by the interaction of two recessive genes. These results provide important clues to further dissect the mechanism of generation of a novel temperature sensitive HB in rice intrasubspecific crosses and suggest that these linked markers will useful in rice breeding.
Cloning and expression of Staphylococcus simulans lysostaphin enzyme gene in Bacillus subtilis WB600

Lysostaphin is a glycylglycine endopeptidase, secreted by Staphylococcus simulans, capable of specifically hydrolyzing pentaglycine crosslinks present in the peptidoglycan of the Staphylococcus aureus cell wall. In this paper, we describe the cloning and expression of the lysostaphin enzyme gene in Bacillus subtilis WB600 host using pWB980 expression system. Plasmid pACK1 of S. simulans was extracted using the alkaline lysis method. Lysostaphin gene was isolated by PCR and cloned into pTZ57R/T-Vector, then transformed into Escherichia coli DH5α. The amplified gene fragment and uncloned pWB980 vector were digested using PstI and XbaІ enzymes and purified. The restricted gene fragment was ligated into the pWB980 expression vector by the standard protocols, then the recombinant plasmid was transformed into B. subtilis WB600 using electroporation method. The recombinant protein was evaluated by the SDS-PAGE method and confirmed by western immunoblot. Analysis of the target protein showed a band corresponding to 27-kDa r-lysostaphin. Protein content was estimated 91 mg/L by Bradford assay. The recombinant lysostaphin represented 90% of its maximum activity at 40 °C and displayed good thermostability by keeping about 80% of its maximum activity at 45 °C. Heat residual activity assay of recombinant lysostaphin demonstrated that the enzyme stability was up to 40 °C and showed good stability at 40 °C for 16 h incubation.
A Hybrid Charger of Conductive and Inductive Modes for Electric Vehicles

Electric vehicles (EVs) are gaining more and more user acceptances due to their clean, efficient, and environmentally friendly nature. Currently, most commercial EVs use conductive charging for their batteries. Inductive charging, which is an alternative charging technology, has recently received a great deal of attention because of its increased user convenience and safety. It is forecast that the two charging technologies will be implemented in future charging infrastructures globally. Consequently, future EVs need to be capable of dealing with both charging methods. So far, there have only been a very few charging topologies reported in the literature that describe both charging methods in the same vehicle. However, solutions that have been proposed do not show a significant component reduction. In this article, we propose a hybrid charger system where the high-frequency transformer of an onboard dc–dc converter becomes the coupling point between the conductive and inductive charging. Using this coupling point, the circuit utilizes the same components for conductive and for inductive charging. This results in the reduction of component count and, therefore, an improved integration. The proposed system is verified by both simulation and experiment. For the experiment, a 3-kW prototype has been built and tested. The maximum efficiency of 97.4% and 93.6% was achieved in the conductive and inductive mode, respectively.
Correlations among natural language processing indicators and critical thinking sub-dimensions in HiEd students

Most of the attempts to develop and validate tools for the automatic assessment of Critical Thinking (CT) related-skills applied Natural Language Processing techniques (NLP) to English written texts, with a few applications in other languages. Therefore, this research was aimed at understanding which NLP features correlates with six CT sub-dimensions in essays written in Italian language. 206 Master Degree students’ pre-post essays were assessed both by human evaluators and by an algorithm which automatically calculates different kinds of NLP features. We found a positive internal reliability and a medium to high inter-coder agreement of the human evaluators. Three NLP indicators significantly correlate with CT total score: Corpus Length , Syntax Complexity , and an adapted measure of Term Frequency-Inverse Document Frequency .
