Genome-Wide Identiﬁcation and Characterization of the GRF Gene Family in Melastoma dodecandrum

: Growth-regulating factor (GRF) is a kind of transcription factor unique to plants, playing an important role in the ﬂowering regulation, growth, and development of plants. Melastoma dodecandrum is an important member of Melastomataceae, with ornamental, medicinal, and edible beneﬁts. The identiﬁcation of the GRF gene family in M. dodecandrum can help to improve their character of ﬂavor and continuous ﬂowering. The members of the GRF gene family were identiﬁed from the M. dodecandrum genome, and their bioinformatics, selective pressure, and expression patterns were analyzed. The results showed that there were 20 GRF genes in M. dodecandrum . Phylogenetic analysis showed that the 71 GRF genes from M. dodecandrum , Arabidopsis thaliana , Camellia sinensis , and Oryza sativa can be divided into three clades and six subclades. The 20 GRF genes of M. dodecandrum were distributed in twelve chromosomes and one contig. Furthermore, the gene structure and motif analysis showed that the intron and motif within each clade were very similar, but there were great differences among different clades. The promoter contained cis-acting elements related to hormone induction, stress, and growth and development. Different transcriptomic expression of MdGRFs indicated that MdGRFs may be involved in regulating the growth and development of M. dodecandrum . The results laid a foundation for further study on the function and molecular mechanism of the M. dodecandrum GRF gene family.
The Influence of Thermomechanical Compaction on the Marginal Adaptation of 4 Different Hydraulic Sealers: A Comparative Ex Vivo Study

Since there are no data in the literature regarding the comparison of the marginal adaptation of hydraulic sealers when used with a single-cone technique or through thermomechanical compaction, this study aimed to evaluate the behavior of four different endodontic sealers used with the two above-mentioned obturation techniques by evaluating the marginal gap existing between the obturation materials and the dentinal walls through scanning electron microscopy. Given this objective, a total of 104 single-rooted, straight canal teeth were selected and divided into four subgroups according to the selected endodontic sealer ((AH) Plus Bioceramic Sealer (AHP), EndoSequence BC Sealer HiFlow (ES), C-Root SP (CR), and GuttaFlow Bioseal (GF)). Each tooth was decoronated and instrumented with the HyFlex EDM/CM systematics up to 30.04. After irrigation procedures, the teeth of each subgroup were divided into two groups and obturated according to two different obturation techniques: the single-cone technique (SC) and the thermomechanical compaction technique (TC). After the required sealer setting time, each tooth was sectioned in three parts at 3, 6, and 9 mm from the apex, and each section was observed with a scanning electron microscope. The marginal gap of each sample was measured using G* Power Software v3.1, and the statistical analysis was performed using the Kruskal–Wallis test, followed by a post hoc Dunn’s test. Results showed that there were not any statistically significant differences in terms of the marginal gap between the two different above-mentioned obturation techniques for each sealer, except for the middle third of root canals, where a statistically significant difference was found for AHP, ES, and GF sealers. In conclusion, the thermomechanical compaction of hydraulic sealers and gutta-percha guarantees better sealing than the single-cone technique when the root canal shape is not rounded.
Modulated Langmuir Probe Characteristics

The presence of fluctuations in the discharge parameters introduces errors into Langmuir probe measurements. Previous work by Garscadden and Emeleus considered the effects of fluctuations in the individual parameters. In this paper a generalized small‐amplitude theory of the effects of these fluctuations is given and also a large signal theory for single‐frequency oscillations. The results of Garscadden and Emeleus can be deduced from these, but additional terms are predicted due to cross modulation occurring when the various fluctuations are correlated. The large signal theory has been checked experimentally in a mercury‐vapor discharge at a pressure of about 1 μ. Further experimental measurements with injected broadband noise signals confirm certain features of the generalized theory. The errors caused by fluctuations are discussed and it is concluded that although electron temperatures may still be measured accurately in their presence, serious errors can be incurred in the measurement of electron satu.
EXISTENCE AND ASYMPTOTIC STABILITY OF SOLUTIONS OF A PERTURBED FRACTIONAL FUNCTIONAL-INTEGRAL EQUATION WITH LINEAR MODIFICATION OF THE ARGUMENT

We study the solvability of a perturbed quadratic functional- integral equation of fractional order with linear modication of the argu- ment. This equation is considered in the Banach space of real functions dened, bounded and continuous on an unbounded interval. Moreover, we will obtain some asymptotic characterization of solutions.
AC-Heating and Fast-Charging Power Requirements of EV Battery Packs in Subzero Temperature

An emerging problem in power engineering pertains to ascertaining the impacts of fast-charging processes of all-electric vehicles (EVs) on electric grids. This problem exacerbates in subzero climates because it is necessary to preheat battery cells within EVs before fast charging to mitigate lithium plating. To study such processes, we set forth detailed and reduced-order simulation models as to determine grid power requirements for ac heating and fast-charging of EVs. The detailed representation considers ac and dc control loops, a four-quadrant power converter, and an estimator of the state of charge (SoC) of the EV battery pack. The reduced-order model has close agreement with detailed real-time (RT) simulation and laboratory experimentation.
Cell-Free DNA in Cerebrospinal Fluid Complements the Monitoring Value of Interleukin-10 in Newly Diagnosed Primary Central Nervous System Lymphoma

Objectives Primary central nervous system lymphoma (PCNSL) usually has a poor prognosis. Cerebrospinal fluid (CSF) interleukin (IL)-10 has shown diagnostic, prognostic, and monitoring value in our previous studies. Cell-free circulating tumor DNA can be detected in the CSF of refractory/relapse cases and has also shown monitoring value. However, information about its monitoring value in newly diagnosed PCNSL patients and comparisons of CSF IL-10 and CSF cell-free DNA (cfDNA) are scarce. Methods We performed next-generation sequencing on paraffin-embedded tissue and the serial CSF cfDNA of 10 newly diagnosed PCNSL patients and on the baseline CSF cfDNA of 11 other central nervous system lymphoma patients. We also monitored the CSF IL-10 levels of the 10 newly diagnosed PCNSL patients. Results In seven newly diagnosed PCNSL patients with sufficient baseline CSF cfDNA, six had ≥1 mutated genes in their CSF cfDNA. The most common were MYD88(4/7), PIM1(3/7), MLL2(3/7), and ETV6(2/7). We also identified multiple somatic mutations, most commonly in PIM1. MYD88L265P can be detected in both tumor tissue and CSF cfDNA. The genomic profiles of CFS cfDNA were similar in PCNSL and PIOL patients. Newly diagnosed PCNSL patients with persistently positive cfDNA and negative IL-10 progressed quickly, while those with negative cfDNA and negative IL-10 were in maintenance therapy for more than 18 months. Two patients without cfDNA had increased CSF IL-10 concentrations before disease relapse. These results indicate that negative CSF cfDNA predicts better results, and persistently positive CSF cfDNA predicts disease progression earlier than conventional magnetic resonance imaging. Conclusion In conclusion, CSF cfDNA is a potential predictor of relapse and progression, which complements the monitoring value of CSF IL-10 in newly diagnosed PCNSL patients.
Analyzing the influence of celebrities’ emotional and rational brand posts

Purpose The purpose of this paper is to compare two brand posts with the different content created by a celebrity (emotional content vs rational content) on Instagram and their effects on users’ willingness to use offline word of mouth (WOM) and electronic WOM (eWOM). The research model also consists of product involvement as the moderator. Design/methodology/approach Based on the results of the pretest stages, the study included two stimuli, and respondents were presented with two different brand posts (i.e. two manipulated pictures and texts on the Instagram frame). A two-group comparison (positive emotional brand post vs negative rational brand post) between-subjects experiment (n = 214) was conducted. Findings The results indicate that WOM and eWOM are more affected by a celebrity’s emotional brand post than a celebrity’s rational brand post. Furthermore, both types of WOM are more affected through high product involvement enhanced by a celebrity’s rational brand post than through high product involvement boosted by a celebrity’s emotional brand post. Practical implications Managerial implications for social media marketing and Instagram celebrity-based branding are provided. Practical implications are also provided in the form of evidence of how the impacts of two different brand posts on positive offline WOM and eWOM are affected differently through the moderation of product involvement. Originality/value The research argues for theoretical implications for the marketing literature on celebrity endorsements. The study also tests one moderating effect on the relationship between brand post content and WOM and eWOM.
Strongly Coupled Plasmon Polaritons in Gold and Epsilon-Near-Zero Bifilms

Epsilon-near-zero (ENZ) polaritons in a thin transparent conducting-oxide film exhibit a significant electric field enhancement and localization within the film at frequencies close to their plasma frequency, but do not propagate. Meanwhile, plasmon polariton modes in thin metallic films can propagate for several microns, but are more loosely confined in the metal. Here, we propose a strongly coupled bilayered structure of a thin gold film on a thin indium tin oxide (ITO) film that supports hybrid polariton modes. We experimentally characterize the dispersion of these modes and show that they have propagation lengths of 4–8 μm while retaining mode confinement greater than that of the polariton in gold films by nearly an order of magnitude. We study the tunability of this coupling strength by varying the thickness of the ITO film and show that ultrastrong coupling is possible at certain thicknesses. The unusual linear and nonlinear optical properties of ITO at ENZ frequencies make these bifilms useful for the active tuning of strong coupling, ultrafast switching, and enhanced nonlinear interactions at near-infrared frequencies.
Spectroscopic Identification of White Dwarfs in the New Luyten Two-Tenths Survey

We spectroscopically identify New Luyten Two-Tenths (NLTT) stars from the reduced proper-motion diagram of Salim & Gould. Five out of 16 objects investigated are identified as white dwarfs: four hydrogen-rich DA stars (NLTT 8581, NLTT 31748, NLTT 53177, and NLTT 56805) and one helium-rich (NLTT 8435). The properties of the stars are further constrained using Two Micron All Sky Survey photometric measurements and, in the case of NLTT 31748, using International Ultraviolet Explorer spectrophotometry. The distances range from 15 to 23 pc, and therefore the sample contributes to estimates of the local density of white dwarf stars. The newly found objects are kinematically consistent with a thick or old thin disk membership. We discuss the likelihood of further identifications.
Purely hopping conduction in c-axis oriented LiNbO3 thin films

Dielectric constant and ac conductivity of highly c-axis oriented LiNbO3 thin film grown by pulsed laser deposition were studied in a metal-insulator-metal configuration over a wide temperature (200 to 450 K) and frequency (100 Hz to 1 MHz) range. The preferred oriented Al (1%) doped ZnO film with electrical conductivity 1.1×103 Ω−1 cm−1 was deposited for dual purpose: (1) to serve as nucleating center for LiNbO3 crystallites along preferred c-axis growth direction, and (2) to act as a suitable bottom electrode for electrical studies. The room temperature dc conductivity (σdc) of LiNbO3 film was about 5.34×10−10 Ω−1 cm−1 with activation energy ∼0.3 eV, indicating extrinsic conduction. The ac conductivity σac was found to be much higher in comparison to σdc in the low temperature region ( 300 K), σac shows a weak frequency dependence, whereas dielectric constant exhibits a strong frequency dispers.
Thrust Stand Characterization of the NASA Evolutionary Xenon Thruster (NEXT)

Abstract Direct thrust measurements have been made on the NASA Evolutionary Xenon Thruster (NEXT) ion engine using a standard pendulum style thrust stand constructed specifically for this application. Values have been obtained for the full 40-level throttle table, as well as for a few off -nominal operating conditions. Measurements differ from the nominal NASA throttle table 10 (TT10) values by 3.1 percent at most, while at 30 throttle levels (TLs) the difference is less than 2.0 percent. When measurements are compared to TT10 values that have been corrected using ion beam current density and charge state data obtained at The Aerospace Corporation, they differ by 1.2 percent at most, and by 1.0 percent or less at 37 TLs. Thrust correction factors calculated from direct thrust measurements and from The Aerospace Corporation’s plume data agree to within measurement error for all but one TL. Thrust due to cold flow and “discharge only” operation has been measured, and analytical expressions are presented which accurately predict thrust based on thermal thrust generation mechanisms.
Similarity Assessment for Assembly Model Based on Component Attributed Relational Graph Matching

3D CAD model retrieval has received a lot of attentions in the academic community. Most existent methods for 3D model similarity assessment focus on component models instead of assembly models. In this paper, an assembly model similarity assessment method is presented in order to find the similar assemblies model for design reuse. First, assembly model is described as component attributed relational graph. Then, the compatibility matrix between two assemblies is calculated, which serves as the measure of their similarity. Finally, the optimal matching under the measures is calculated using Hungarian Method. Experimental results show that this method is able to support the assembly similarity evaluation.
Measurement Reduction Methods for Processing Tomographic Images

The importance of development of new methods for reconstruction of an object image given its sinogram and some additional information about the object stems from the possibility of artifact presence in the reconstructed image, or its insufficient sharpness when the used additional information does not hold. The problem of recovering artifact-free images of the studied object from tomography data is considered in the framework of the theory of computer-aided measuring systems. Methods for solving it are developed. They are based on narrowing the class of possible images using less artifact-inducing information. An example of such information is the natural condition of non-negativeness of the estimated brightnesses. The main problem that arises is the large dimensionality of the images, which prevents the use of direct algorithms. One proposed method is based on local approach, namely correction of the result of unfiltered backprojection by applying a locally (in the space of the output image) optimal linear transformation. Another method processes a sinogram directly, without using backprojection, using iterative implementation of the measurement reduction technique. Examples of use of the proposed methods for processing teeth sinograms are given.
Effects of Voluntary Sodium Consumption during the Perinatal Period on Renal Mechanisms, Blood Pressure, and Vasopressin Responses after an Osmotic Challenge in Rats

Cardiovascular control is vulnerable to forced high sodium consumption during the per-inatal period, inducing programming effects, with anatomical and molecular changes at the kidney, brain, and vascular levels that increase basal and induce blood pressure. However, the program- ming effects of the natriophilia proper of the perinatal period on blood pressure control have not yet been elucidated. In order to evaluate this, we studied the effect of a sodium overload challenge (SO) on blood pressure response and kidney and brain gene expression in adult offspring exposed to voluntary hypertonic sodium consumption during the perinatal period (PM-NaCl group). Male PM-NaCl rats showed a more sustained increase in blood pressure after SO than controls (PM-Ctrol). They also presented a reduced number of glomeruli, decreased expression of TRPV1, and increased expression of At1a in the kidney cortex. The relative expression of heteronuclear vaso- pressin (AVP hnRNA) and AVP in the supraoptic nucleus was unchanged after SO in PM-NaCl in contrast to the increase observed in PM-Ctrol. The data indicate that the availability of a rich source of sodium during the perinatal period induces a long-term effect modifying renal, cardiovascular, and neuroendocrine responses implicated in the control of hydroelectrolyte homeostasis.
Microstructural studies of diamond thin films grown by electron cyclotron resonance-assisted chemical vapor deposition

A detailed investigation of the correlation among intrinsic stress (σint), nonuniform stress (σnu), and phonon lifetime (1/Γ) was performed in order to obtain a coherent and comprehensive picture of the microstructure of diamond thin films grown by the electron cyclotron resonance-assisted chemical vapor deposition (ECR-CVD) technique. It was found that the diamond growth taking place by the ECR-CVD is different to that taking place by the microwave CVD and hot-filament CVD. Point and line defects, rather than sp2 C bonds, were found to be the dominant source of both nonuniform stress and reduced phonon lifetime. The surface relaxation mechanism in these films yields sp2 C at the expense of strained sp3 C, resulting in a trade off between diamond yield and crystalline quality. The diamond precursor that spontaneously forms on the unseeded substrates yielded higher quality diamond than planted diamond seeds. The grain boundary relaxation model proposed by Hoffman accounts well for the observed behavior of .
Whose job is it anyway? A qualitative investigation into the influence of agents, race organisers, and sponsors on the risk of doping in elite distance running

ABSTRACT Agents, race-organisers, and sponsors have a key influence in shaping the world of elite professional distance running. Yet to date this important but hard-to-reach stakeholder group has been omitted from the global research landscape of doping and anti-doping. The purpose of this study is to address this gap in the literature and explore the systematic contributors to doping in elite long-distance running, along with potential solutions to this issue, from this influential perspective. Thirteen in-depth interviews were conducted with agents (n = 8) of world-class long-distance runners, major race organisers (n = 3), and sports marketing managers for global brands (n = 2). The interviews were conducted via the phone, audio-recorded, and transcribed verbatim. Reflexive thematic analysis generated three themes which focused on: 1) The framework of professional distance running and the contextual aspects which may contribute to doping risk, 2) the impact of various recruitment strategies on doping and anti-doping, and 3) the lessons that can be learnt from the participants’ first-hand experiences with doping cases and/or managing anti-doping requirements. Reflecting on the sector rather than the sample, the results highlighted that not all commercial stakeholders feel responsible for anti-doping. Collective responsibility from all stakeholders, which is currently borne by some and not others, is necessary to minimise doping in distance running. The challenge is how to convince all stakeholders of their share of the responsibility.
Carbon tax acceptance in a polarized society: bridging the partisan divide over climate policy in the US

ABSTRACT Political polarization in the US hinders bipartisan support for carbon taxes. Polarization operates unconsciously via implicit biases (implicit level), but it also arises when individuals consciously reflect on their political identity and beliefs (explicit level). We conducted two survey experiments with online panels of the US population to examine how irreconcilable Democrats’ and Republicans’ views on carbon taxes are. Study 1 compared measurements from an Implicit Association Test (implicit level) and stated beliefs (explicit level). Results show carbon tax fairness perceptions were already polarized at implicit level, but the main divergence in attitudes occurred at explicit level. Since explicit attitudes are considered easier to influence than implicit ones, Study 2 tested the extent to which message framing could influence this deliberated—explicit—polarization. We used different frames targeted at Democrats and Republicans to convey the idea that carbon tax support does not threaten partisans’ political identity. Framings further polarized responses, increasing Democrats’ but reducing Republicans’ policy support. We discuss implications for climate policy communication in relation to navigating identity-based polarization. Policy Highlights Political polarization over climate policy in the US is driven by the interplay of affective and cognitive factors. Unconscious fairness perceptions about carbon taxes are already polarized. These differences amplify when Democrats and Republicans consciously report their perceptions. Identity-affirming framings that appeal to partisans’ concerns can influence carbon tax acceptance. Since Republicans may react negatively to climate policy communication, source credibility might be necessary to avoid backlash.
High-speed switching of nanoscale ferroelectric domains in congruent single-crystal LiTaO3

The nanodomain reversal characteristics of congruent LiTaO3 (CLT) single crystal are investigated. It is found that fast nanosecond domain switching can be achieved by reducing the sample thickness, even for CLT, which contains many Li vacancy defects that pin domain-wall movement. As an example, the authors obtain a polarization inverted domain dot with a radius of 7.9 nm by application of a 4 ns 10 V pulse. These results demonstrate that the speed of polarization reversal is closely related to the thickness of the medium.
