ASPECTOS FLORAIS E REPRODUTIVOS DE Psychotria capitata RUIZ & PAVON (RUBIACEAE), UM CASO DE DISTILIA TÍPICA NO CERRADO

BREEDING SYSTEMS AND POLLINATION OF THE PSYCHOTRIA CAPITATA RUIZ & PAVON (RUBIACEAE): A CASE THE TYPICAL DISTYLY IN CERRADO: The phenotypic integration observed in flowers is an evolutionary strategy that aims to increase the pollen flow between individuals, favoring the crossing and maintenance of genetic variability. This success is directly related to the floral structure, such as hermaphroditism, and to the behavior of visitors, and can generate conflicts between the floral structures, being selected characteristics that reduce this conflict and amplify the pollen flow, as is the case of heterostyly. The objective of the study was to describe the floral characteristics, the reproductive system, and pollination in Psychotria capitata Ruiz & Pavon (Rubiaceae). For this purpose, the floral structures were measured and observed, controlled crossings were carried out, the floral visitors were observed and the nectar production was evaluated. Psychotria capitata is a typical dystylic species, shrub with a maximum height of 3 meters, with high rates of reciprocal hercogamy between the floral morphs. It has white tubular flowers, visited by a wide range of insects, including moths, bees, wasps and flies. There was higher fruit formation in intermorphic cross-pollination (> 60 %) and lower formation in intramorphic (< 20 %) and self-pollination (< 15 %), characterizing self and intramorphic incompatibility. These data were confirmed by the non growth of pollen tubes in self-pollinated pistils and intramorphic pollinators. Blooming is annual, and occurs between the months of October and January, with peak blooming in November and December. The reproductive data evaluated are similar to other Rubiaceae species in the Cerrado forest sub forest. These data enrich the reproductive knowledge of Rubiaceae's sub-forest species, so important for the maintenance of fauna in forest fragments.
Augmented Lagrangian-Based First-Order Methods for Convex-Constrained Programs with Weakly Convex Objective

First-order methods (FOMs) have been widely used for solving large-scale problems. A majority of existing works focus on problems without constraint or with simple constraints. Several recent works have studied FOMs for problems with complicated functional constraints. In this paper, we design a novel augmented Lagrangian (AL)–based FOM for solving problems with nonconvex objective and convex constraint functions. The new method follows the framework of the proximal point (PP) method. On approximately solving PP subproblems, it mixes the usage of the inexact AL method (iALM) and the quadratic penalty method, whereas the latter is always fed with estimated multipliers by the iALM. The proposed method achieves the best-known complexity result to produce a near Karush–Kuhn–Tucker (KKT) point. Theoretically, the hybrid method has a lower iteration-complexity requirement than its counterpart that only uses iALM to solve PP subproblems; numerically, it can perform significantly better than a pure-penalty-based method. Numerical experiments are conducted on nonconvex linearly constrained quadratic programs. The numerical results demonstrate the efficiency of the proposed methods over existing ones.
Design and Control of a New Compound Double-Rotor Electric Machine for Hybrid Propulsion System

In this article, a new compound consequent-pole double-rotor electric machine (CCPDRM) is proposed for hybrid propulsion system application. First, the operating principle and harmonic components in CCPDRMs are elucidated. The winding factor theory for conventional permanent magnet (PM) electric machines is further extended and applied in CCPDRMs. Then, this improved theory is adopted to investigate the structure and winding scheme requirement of the proposed CCPDRMs. In addition, the control strategy for the proposed CCPDRM is established. By utilizing a parameter sweep method, the variation trends of CCPDRMs’ torque density with respect to various geometrical parameters are revealed. Based on this, the structure of CCPDRMs is optimized to acquire a better electromagnetic performance. Next, the proposed CCPDRM is compared with a conventional compound bipolar double-rotor electric machine (CBDRM). It is found that the improved topology has a similar torque density but a much higher PM utilization factor and a lower PM demagnetization risk when compared with the CBDRM. Finally, a prototype is manufactured and tested in different operating modes. Furthermore, various mode-switching processes are performed to emulate the practical driving cycle of hybrid transportation. Both steady-state and dynamic mode-switching experimental results prove the effectiveness of CCPDRMs.
Mutual Influence in LGBTQ Teens’ Use of Media to Socialize Their Parents

ABSTRACT Recent theorizing posits that parents and their children influence each other, and that media use is a locus of such mutual influence. Two surveys of LGBTQ 18- and 19-year-olds (N = 276; N = 369, the latter a replication) tested hypotheses that LGBTQ teens use media to socialize their parents about their sexual and gender identities, and that these uses elicit parental responses which have implications for the teen. In both studies, teens reported co-viewing and mediating their parents’ exposure to LGBTQ content (i.e., encouraging positive exposure, discouraging negative exposure, critiquing/explicating depictions) and indicated that such moments sometimes elicited conversations about their own sexual or gender identities. In both studies, their perceptions of their parents’ receptivity to these interactions varied widely. In both studies, teens’ LGBTQ-media-related behavior and perceptions of parental receptivity were positively associated with perceptions that their parents supported their LGBTQ identity. Perceived receptivity (in Study 1) and perceived support for the teens’ LGBTQ identities (in Study 2) were associated with teens’ self-esteem and depressive symptoms. Overall, despite some inconsistencies between the two studies and the limitations of cross-sectional data, the findings are consistent with mutual influence.
Peridynamic Modeling and Simulation of Ice Craters By Impact

In the present work, a state-based peridynamics with adaptive particle refinement is proposed to simulate water ice crater formation due to impact loads. A modified Drucker-Prager constitutive model was adopted to model ice and was implemented in the state-based peridynamic equations to analyze the elastic-plastic deformation of ice. In simulations, we use the fracture toughness failure criterion in peridynamics to simulate the quasi-brittle failure of ice. An adaptive particle refinement method in peridynamics was proposed to improve computational efficiency. The results obtained using the peridynamic model were compared with the experiments in previous literatures. It was found that the peridynamic simulation results and the experiments matched well except for some minor differences discussed, and the state-based peridynamic model has shown the specific predictive capacity to capture the detailed crater features of the ice.
Analysis of Fine Crack Images Using Image Processing Technique and High-Resolution Camera

Visual inspections are performed to investigate cracks in concrete infrastructure. These activities require manpower or equipment such as articulated ladders. Additionally, there are health and safety issues because some structures have low accessibility. To deal with these problems, crack measurement with digital images and digital image processing (DIP) techniques have been adopted in various studies. The objective of this experimental study is to evaluate the optical limit of digital camera lenses as working distance increases. Three different lenses and two digital cameras were used to capture images of lines ranging from 0.1 to 0.5 mm in thickness. As a result of the experiments, it was found that many elements affect width measurement. However, crack width measurement is dependent on the measured pixel values. To accurately measure width, the measured pixel values must be in decimal units, but that is theoretically impossible. According to the results, in the case of 0.3 mm wide or wider cracks, a working distance of 1 m was secured when the focal length was 50 mm, and working distances of 3 m and 4 m were secured when the focal length was 100 mm and 135 mm, respectively. However, for cracks not wider than 0.1 mm, focal lengths of 100 mm and 135 mm showed measurability within 1 m, but a focal length of 50 mm was judged to hardly enable measurement except for certain working positions. Field measurement tests were conducted to verify measurement parameters identified by the results of the indoor experiment. The widths of actual cracks were measured through visual inspection and used for the analysis. From the evaluation, it was confirmed that the number of pixels corresponding to the working distance had a great influence on crack width measurement accuracy when using image processing. Therefore, the optimal distance and measurement guidelines required for the measurement of the size of certain objects was presented for the imaging equipment and optical equipment applied in this study.
Recent Activity and Kinematics of the Bounding Faults of the Catanzaro Trough (Central Calabria, Italy): New Morphotectonic, Geodetic and Seismological Data

A multidisciplinary work integrating structural, geodetic and seismological data was performed in the Catanzaro Trough (central Calabria, Italy) to define the seismotectonic setting of this area. The Catanzaro Trough is a structural depression transversal to the Calabrian Arc, lying in-between two longitudinal grabens: the Crati Basin to the north and the Mesima Basin to the south. The investigated area experienced some of the strongest historical earthquakes of Italy, whose seismogenic sources are still not well defined. We investigated and mapped the major WSW–ENE to WNW–ESE trending normal-oblique Lamezia-Catanzaro Fault System, bounding to the north the Catanzaro Trough. Morphotectonic data reveal that some fault segments have recently been reactivated since they have displaced upper Pleistocene deposits showing typical geomorphic features associated with active normal fault scarps such as triangular and trapezoidal facets, and displaced alluvial fans. The analysis of instrumental seismicity indicates that some clusters of earthquakes have nucleated on the Lamezia-Catanzaro Fault System. In addition, focal mechanisms indicate the prevalence of left-lateral kinematics on E–W roughly oriented fault plains. GPS data confirm that slow left-lateral motion occurs along this fault system. Minor north-dipping normal faults were also mapped in the southern side of the Catanzaro Trough. They show eroded fault scarps along which weak seismic activity and negligible geodetic motion occur. Our study highlights that the Catanzaro Trough is a poliphased Plio-Quaternary extensional basin developed early as a half-graben in the frame of the tear-faulting occurring at the northern edge of the subducting Ionian slab. In this context, the strike-slip motion contributes to the longitudinal segmentation of the Calabrian Arc. In addition, the high number of seismic events evidenced by the instrumental seismicity, the macroseismic intensity distribution of the historical earthquakes and the scaling laws relating to earthquakes and seismogenic faults support the hypothesis that the Lamezia-Catanzaro Fault System may have been responsible for the historical earthquakes since it is capable of triggering earthquakes with magnitude up to 6.9.
An explicit finite volume scheme on staggered grids for the Euler equations: Unstructured meshes, stability analysis, and energy conservation

We set up a numerical strategy for the simulation of the Euler equations, in the framework of finite volume staggered discretizations where numerical densities, energies, and velocities are stored on different locations. The main difficulty relies on the treatment of the total energy, which mixes quantities stored on different grids. The proposed method is strongly inspired, on the one hand, from the kinetic framework for the definition of the numerical fluxes, and, on the other hand, from the discrete duality finite volume (DDFV) framework, which has been designed for the simulation of elliptic equations on complex meshes. The time discretization is explicit and we exhibit stability conditions that guaranty the positivity of the discrete densities and internal energies. Moreover, while the scheme works on the internal energy equation, we can define a discrete total energy which satisfies a local conservation equation. We provide a set of numerical simulations to illustrate the behavior of the scheme.
Effects of Cognitive Training Programs on Executive Function in Children and Adolescents with Autism Spectrum Disorder: A Systematic Review

Background. Autism Spectrum Disorder is often associated with deficits in executive functions (EFs), which is contributing significantly to individuals with ASD’s difficulties in conducting an independent life, particularly considering social skills. Technologies offer promising opportunities to structure EF intervention programs for children on the autistic spectrum. Methods. This study aimed to review the effectiveness of randomized controlled trials or quasi-experimental studies of EF interventions delivered to children and young people (up to 23 years old) with a diagnosis of ASD. A special focus was dedicated to document the effectiveness of computerized and non-computerized cognitive training on (1) EFs and on (2) ASD symptomatology and social skills. Of 2601 studies retrieved, 19 fulfilled the inclusion criteria. Results. Most of the interventions identified were effective in enhancing EFs and reducing symptoms in children and young people with ASD. Limited evidence is available on their generalization to untrained skills (i.e., social abilities) as well as long-term effects. Conclusions. There is growing evidence for overall effectiveness of EF training, particularly when computerized. However, caution should be taken when interpreting these findings owing to methodological limitations, the minimal number of papers retrieved, and a small samples of included studies.
Introduction: Time and Narrative, the Missing Link between the “Narrative Turn” and Postclassical Narratology?

The three volumes of Time and Narrative (1983 – 85) were published — and soon translated to English (1984 – 88) — in a pivotal moment for narrative studies and for narratology. In the middle of the eighties, the interest in narratives began to spread beyond the traditional fields of literary studies and linguistics and to influence almost all humanities disciplines. However, this remarkable expansion of narrative studies is disconnected from the evolution of narratology, which at the same time entered a period of “crisis” (RimmonKenan 1989), before its revival under the label of “postclassical narratology” (Herman 1997). Indeed, there is a tension between, on the one side, the proliferation of narrative studies throughout the 1980s and 1990s, and on the other side, the loss of interest in the theorization of
Maximising Operational Effectiveness: Exploring Stigma, Militarism, and the Normative Connections to Military Partners’ Support-Seeking

Non-serving partners of personnel in the British military endure numerous challenges due to their association with the Armed Forces and complex systems of support exist to mitigate some disadvantages they might experience. Military research suggests that support-seeking can be stigmatised, limiting the effectiveness of existing support systems. However, it seldom engages with how stigma is produced, often obscuring reflection on normative and disciplinary power, rendering discussions politically anesthetised. Through the thematic analysis of welfare policy and provision, interviews with welfare-providers and military partners, this article develops understandings of stigma as a barrier to support-seeking, considering how it is produced and how it is productive of gendered militarised neoliberalism.
Physicochemical, Photocatalytic, Antibacterial, and Antioxidant Screening of Bergenia Ciliata Mediated Nickel Oxide Nanoparticles

This study was planned to synthesize a multifunctional nanomaterial that can effectively encounter the organic pollutants, multidrug-resistant bacteria and reactive free radicals. The Bergenia ciliate (B. ciliate) leaves extract was used as a reducing and capping agent for the synthesis of nickel oxide nanoparticles (NiO NP). The physicochemical properties were studied through X-ray diffractometre (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-visible and Fourier transform infrared (FTIR) spectroscopies. The highly crystalline monoclinic NiO NPs were synthesized with crystallite size of 27.45 nm. The average particle size derived from TEM micrograph was 49.35 nm whereas the calculated band gap for NiO NPs was 3.78 eV. The photocatalytic study shows that 92.17% of the rhodamine 6G (Rh-6G) was efficiently degraded in the presence of NiO NPs. The agar well diffusion method was applied to examine the antibacterial activity of NiO NPs and the activity was found higher against Gram-negative bacteria (GNB) as compared to Gram-positive bacteria (GPB). The ABTS free radical scavenging activity was also performed, however, the activity was found less than the standard.
Análise de Estabilidade do LMS segundo a Teoria de Lyapunov

— This work presents a stability analysis of the LMS algorithm based on deterministic and stochastic Lyapunov approaches. In both cases it is shown to be possible to obtain expressions for the maximum value of the adaptation step-size without necessarily resorting to simplifying hypotheses such as the independence theory. This reveals interesting perspectives of studies concerning aspects like convergence rate and misadjustment.
Addition of Different Biochars as Catalysts during the Mesophilic Anaerobic Digestion of Mixed Wastewater Sludge

Biochar (BC) recently gained attention as an additive for anaerobic digestion (AD). This work aims at a critical analysis of the effect of six BCs, with different physical and chemical properties, on the AD of mixed wastewater sludge at 37 °C, comparing their influence on methane production and AD kinetics. AD batch tests were performed at the laboratory scale operating 48 reactors (0.25 L working volume) for 28 days with the addition of 10 g L−1 of BC. Most reactors supplemented with BCs exhibited higher (up to 22%) methane yields than the control reactors (0.15 Nm3 kgVS−1). The modified Gompertz model provided maximum methane production rate values, and in all reactors the lag-phase was equal to zero days, indicating a good adaptation of the inoculum to the substrate. The potential correlations between BCs’ properties and AD performance were assessed using principal component analysis (PCA). The PCA results showed a reasonable correlation between methane production and the BCs’ O–C and H–C molar ratios, and volatile matter, and between biogas production and BCs’ pore volume, specific surface area, and fixed and total carbon. In conclusion, the physic-chemical properties of BC (specifically, hydrophobicity and morphology) showed a key role in improving the AD of mixed wastewater sludge.
Contradicción, antagonismo y hegemonía. Debates teóricos para el análisis contemporáneo del populismo

El artículo propone un debate teórico acerca de las categorías de contradicción y antagonismo, en el marco de la teoría de la hegemonía, evaluando su vigor y actualidad para el análisis contemporáneo del populismo. En ese camino, pondremos en cuestión las críticas de Laclau al marxismo, particularmente en relación con la categoría de contradicción, con el fin de replantear su vigencia y articularla con distintas herramientas teóricas provenientes del pensamiento laclausiano para el análisis de la hegemonía, observando la dinámica del antagonismo y la constitución identitaria de sujeto. Algunas de las preguntas que emergen son las siguientes. ¿Cómo profundizar en el análisis de las lógicas instituyentes de lo político sin perder de vista la gravitación de los factores económico-estructurales? ¿Cuáles son las relaciones entre el pueblo y las clases sociales? ¿Cómo re-articular los aportes del pensamiento de Laclau en el marco de la teoría gramsciana de la hegemonía?
Constraints on the preservation of proxy data in carbonate archives – lessons from a marine limestone to marble transect, Latemar, Italy

This work evaluates an exceptionally complex natural laboratory, the Middle Triassic Latemar isolated platform in the northern Italian Dolomite Mountains and explores spatial and temporal gradients in processes and products related to contact metamorphism, dolomitization and dedolomitization of marine limestones. The relation between petrographic change and re‐equilibration of geochemical proxy data is evaluated from the perspective of carbonate‐archive research. Hydrothermal dolomitization of the limestone units is triggered by dykes and associated hydrothermal fluids radiating from the nearby Predazzo Intrusion. Detailed petrography, fluid inclusion analysis, δ13C and δ18O data and 87Sr/86Sr isotope ratios shed light on the extreme textural and geochemical complexity. Metamorphic and diagenetic patterns include: (i) peak‐metamorphic and retrograde‐metamorphic phases including three dolomite marbles, two dedolomite marbles, brucite, magnesium silicates and late‐stage meteoric/vadose cement at the contact aureole; (ii) four spatially defined episodes of dolomitization, authigenic quartz, low magnesium calcite and late‐stage meteoric cement at the Latemar isolated platform; and (iii) kilometre‐scale gradients in δ13C values from the contact aureole towards the platform interior. Results shown here are relevant for two reasons: first, the spatial analysis of alteration products ranging from high‐grade metamorphic overprint of marbles at temperatures of 700°C in the contact aureole to moderately altered limestones in the platform interior at temperatures <100°C, allows the observation of processes that commonly occur along vertical (prograde) gradients from shallow burial to metamorphism at depths >20 km. Second, under rock‐buffered conditions, and irrespective of metamorphic to diagenetic fluid−rock interactions, both marbles, and low‐temperature hydrothermal dolomites have conservative marine δ13C and δ18O values. The fact that metamorphism and hydrothermal dolomitization of precursor limestones and early diagenetic dolostones did not per se reset environmental proxy data is of interest for those concerned with carbonate archive research in Earth’s deep time.
A REVIEW OF SPATIAL ECONOMETRICS IN EXPLICIT LOCATION MODELLING OF COMMERCIAL PROPERTY MARKET

‘Location, location, location’ is a real property parlance mostly used to describe the influence of location in the property market. Location is mainly considered as the most significant influencer of commercial property prices. Location is modelled traditionally using hedonic pricing model by either proxy location dummies or distances relative to other neighbourhood features. This was shown to be inadequate due to spatial autocorrelation and heterogeneity inherent in spatial data, which jeopardises the estimates' consistency. Consequently, spatial econometrics is used to explicitly model location into property pricing by controlling spatial effects of autocorrelation and heterogeneity. Housing studies dominate the use of this approach with limited application in the commercial property market. This paper reviewed spatial econometrics and found that the commercial property market exhibits significant spatial dependence and heterogeneity. Accounting for such effects improves model accuracy significantly. It, therefore, recommends increase use of spatial econometrics in commercial property market modelling.
