Avifauna of Serra Vermelha, southern Piauí, Brazil

The region into which Serra Vermelha is inserted, southern Piaui State, has one of the most extensive and preserved portions of arboreal caatinga and seasonal semi-deciduous forests of the biome. During 19-30 September 2008, the avifauna of this region was inventoried, making possible the registration of 179 species of birds. Of these, five are found in the official Brazilian List of Fauna Threatened with Extinction: Penelope jacucaca, Anodorhynchus hyacinthinus, Xiphocolaptes falcirostris, Sclerurus scansor cearensis and Procnias averano. The record of Asio clamator represents the first of the species in the state of Piaui; besides Anodorhynchus hyacinthinus, Ramphastos toco, Ramphocelus carbo and Psarocolius decumanus, representing the first records of these species in caatinga. There are a further 15 species endemic to the biome occurring in Serra Vermelha: Penelope jacucaca, Aratinga cactorum, Hydropsalis hirundinacea, Anopetia gounellei, Picumnus pygmaeus, Sakesphorus cristatus, Thamnophilus capistratus, Herpsilochmus sellowi, Hylopezus ochroleucus, Xiphocolaptes falcirostris, Gyalophylax hellmayri, Megaxenops parnaguae, Sporophila albogularis, Paroaria dominicana and Icterus jamacaii. Generally, the avifauna encountered in Serra Vermelha is strongly related to that of caatinga. Despite being situated on the limit with cerrado, endemic species of this biome were not recorded, nor were species typical of other adjacent biomes such as Amazonia and the Atlantic Forest. Forest formations of caatinga are priority areas for conservation, not only because they represent irreplaceable environments within the biome, but also because they are suffering most of the deforestation pressure in the caatinga. In this sense, the inclusion of these forest formations within the Brazilian system of Conservation Units, principally those situated in southern Piaui, as in the case of Serra Vermelha, must be considered an urgent and necessary measure for the maintenance of all natural communities associated with seasonal semi-deciduous caatinga forests.

Localization of the Porion Landmark in Orthodontics: A Comparison of the Efficiency of NEMO-Ceph 2020 Software between Inexperienced and Expert Operators

This study discusses the utility of the NEMO-Ceph 2020 software in localizing the cephalometric landmark known as the Porion point (Po) and the Frankfurt plane in orthodontics. It highlights the challenges in locating the Porion point due to anatomical variations and external factors. The use of radiographs as a diagnostic method is mentioned, along with the need for new tools to aid in locating the Porion landmark. The study employed a database of 179 teleradiographs from the “UCAM DENTAL” database, processed using NEMO-Ceph 2020® software. Inexperienced operators (4th and 5th-year dentistry students) and an expert operator participated. Linear measurements and angular differences were analyzed using the software. Results revealed discrepancies in the Porion point’s location among operators, with mean discrepancies of 2.42 mm (X-axis) and 2.23 mm (Y-axis). The mean discrepancy between Porion points was 2.47 mm, and with the Frankfurt point was 2.44 mm. No statistically significant correlation existed between discrepancies in the X and Y axes. The study concluded that there was a significant difference in Porion point location between inexperienced operators and the expert, and that NEMO-Ceph 2020® software required expert operators for accurate localization of cephalometric landmarks and could not predict the point independently.
RF Genesis: Zero-Shot Generalization of mmWave Sensing through Simulation-Based Data Synthesis and Generative Diffusion Models

This paper presents RF Genesis ( RFGen ), a novel and cost-effective method for synthesizing RF sensing data using cross-modal diffusion models, in order to improve the generalization capability of millimeter-wave (mmWave) sensing systems. Traditional machine learning models used in mmWave sensing struggle with limited training datasets. Their performance degrades drastically when confronted with unseen users, environments, sensor configurations, test classes, etc. RFGen mitigates these challenges by using a cross-modal generative framework to synthesize and expand mmWave sensing data. We specifically propose a custom ray tracing simulator to simulate RF propagation and interaction with objects/environments. We then leverage a set of diffusion models to generate massive 3D scenes, and transform the visual scene representation into the corresponding mmWave sensing data, under the direction of application-specific “prompts”. Our proposed approach reconciles the physics-based ray tracing with the black-box diffusion model, leading to accurate, scalable, and explainable vision-to-RF data synthesis. Our extensive real-world experiments highlight RFGen ’s effectiveness in diverse mmWave sensing applications, enhancing their generalization to unseen test cases without laborious data collection.

Digital restoration offers new avenues for conserving historical artworks, yet presents unique challenges. This research delves into the balance between traditional restoration methods and the use of generative artificial intelligence (AI) tools, using Antoine François Callet’s portrayal of Achilles Dragging Hector’s Body Past the Walls of Troy as a case study. The application of Easy Diffusion and Stable Diffusion 2.1 technologies provides insights into AI-driven restoration methods such as inpainting and colorization. Results indicate that while AI can streamline the restoration process, repeated inpainting can compromise the painting’s color quality and detailed features. Furthermore, the AI approach occasionally introduces unintended visual discrepancies, especially with repeated application. With evolving restoration tools, adaptability remains crucial. Integrating both AI and traditional techniques seems promising, though it is essential to maintain the artwork’s inherent authenticity. This study offers valuable perspectives for art historians, conservators, and AI developers, enriching discussions about the potential and pitfalls of AI in art restoration.

THE EFFECT OF DROUGHT ON YIELD AND MORPHOLOGIC CHARACTERISTICS OF DERACOCEPHALUM MOLDAVICA L.

In order to investigate the effect of drought stress on yield and morphologic characteristics of Deracocephalum moldavica L. under field condition, this research wsa conducted in 2004-2005 at Alborz station. Experiment was carried out in a split plot with randomized complete block design with four replications. Main factors consisted of three plant populations of Deracocephalum moldavica L. which were collected from Tehran, Esfahan and Farse provinces. Subplots consisted of three level of drought stress (100%, 60% and 40% Fc). The results showed the effect of different plant population on morphological characteristics and yield were not significant. Effect of drought stress on length, cross and leaf surface, high plant, stem diameter, lateral shoot, length of highest internodes, weight of 1000 grain and flower shoot, leaf, stem and biological yield were significant. Mean of treatments showed that control (without drought stress treatments) at first and second years were 4126 and 4033 kg/ha of flower shoot and 4929 and 4921 kg/ha biological yield had significant differences with other drought levels. Mean of interaction effects of main and sub plots not showed significant difference for shoot flower production. Highest biological yield was related to controls of three plant population which were different to other treatments. It could be included from this investigation that mild stress could be applied in complete flower stage harvest.
Quantitative Visualization of Flow Fields Associated with Alluvial Sand Dunes: Results from the Laboratory and Field Using Ultrasonic and Acoustic Doppler Anemometry

This paper presents results detailing the quantitative visualization of flow fields associated with natural sand dunes, Fraser River Estuary, Canada, using the complementary approaches of laboratory modelling and field instrumentation. Ultrasonic Doppler velocity profiling is used in the laboratory to elucidate the mean flow fields of low-angle dunes (leeside slope angle ~14˚) that are typical of many large natural rivers. These dunes do not possess a zone of permanent flow separation in the dune leeside and have a velocity structure that is dominated by the effects of flow acceleration and deceleration generated by topographic forcing of flow over the dune form. Turbulence associated with these dunes appears linked to both longer-period shear layer flapping and eddy generation along the shear layer. The field study uses acoustic Doppler profiling to reveal similar mean flow patterns and shows that flow is dominated by deceleration in the leeside without the presence of a region of permanent separated flow.
Use of continuous simulation for the selection of an appropriate urban rainwater tank

Abstract Household rainwater tanks form part of an integrated urban water cycle management system, which is a key aspect of the water sensitive urban design philosophy. They provide scope for harvesting rainwater for domestic uses, as well as mitigating the impacts of urbanisation on catchment runoff. This paper describes the development and application of a computer simulation model for the operation of a household rainwater tank. The model uses daily rainfall and consumption data to simulate the operation of the rainwater tank. The simulation model has been applied to a hypothetical household and rainwater tank system using daily rainfall data for 12 cities throughout Australia. The study indicates that the unit cost of supplying rainwater to a household from a rainwater tank increases as the consumption rate decreases. An economic optimum size rainwater tank, based on the minimum unit cost of rainwater supplied can be determined for any water consumption scenario. The climate characteristics of the site are shown to have a significant influence on the hydrologic effectiveness of the rainwater tank system. The study has shown that the yield of rainwater from the tank is a function of the monthly variation in rainfall, defined by the seasonality index, the median annual rainfall and the tank volume. This may have significant consequences on the suitability of rainwater tanks in terms of potential effects of climate change.
Middle Devonian Moellerina greenei Zone and Suppression of the Genus Weikkoella Summerson, 1958

Weikkoella Summerson, 1958, described from the Columbus Limestone of central Ohio as an arenaceous foraminiferal genus, is based on siliceous steinkerns of the oospores of charophyte gyrogonites referable to Moellerina greenei Ulrich, 1886. M. greenei is found in the Middle Devonian Columbus Limestone of Ohio in the E zone, F zone, G zone and H zone of Stauffer (1 909). In southern Indiana and northwestern Kentucky, the Brevispirifer gregarius Zone of the definitely Onondagan portion of the Middle Devonian Jeffersonville Limestone and the new M. greenei Zone coincide, but in Ohio M. greenei ranges higher than B. gregarius, which does not occur in the H zone. The orientation of the gyrogonites of Moellerina greenei is reinterpreted on the basis of definitive apical and basal structures as determined by a study of the oogonia of modern charophytes.

Effect of Water on the Behavior of a Quartz-Rich Sand Under High Stresses

ABSTRACT The effect of water on the mechanical properties of a quartz-rich sand is investigated by using the results obtained from high pressure triaxial tests on the sand in both dry and saturated states. It is shown that water increases the compressibility and decreases the shear strength of the sand under high pressures, and that these phenomena have a close relation with the activation of particle-crushing in the presence of water. The mechanism of the water action on the lowering of particle strength is investigated from a mechano-chemical viewpoint, and it is concluded that the water sensitivity of the sand is probably due to the surface energy change of cracks which would be produced in each particle under high stresses.
Separate Adaptive Mechanisms for Controlling Trajectory and Separate Adaptive Mechanisms for Controlling Trajectory and Final Position in Reaching Final Position in Reaching

We examined control of the hand's trajectory (direction and shape) and final equilibrium position in horizontal planar arm movements by quantifying transfer of learned visuomotor rotations between two tasks that required aiming the hand to the same spatial targets. In a trajectory-reversal task (“slicing”), the hand reversed direction
Gender Differences in the Group Dynamics of Smaller CS1 Project Groups

Abundant research has investigated gender differences from the perspective of the individual, but little research has explored gender differences from a group perspective. This paper presents a survey-based quantitative exploration of gender differences when $N=138$ students working in smaller (3 students) groups that are either men-majority (WMM) or men-only (MMM). The study was conducted during four weeks of CS1 project work, and the investigation focused on student struggle, task division, group satisfaction, and course outcomes. We observed four significant gender differences: (i) Many women students express a lack of confidence early in the project work, as do many men students that are part of mixed-gender (WMM) groups, but not men that are part of men-only (MMM) groups; (ii) In men-majority groups, women perform more ‘non-technical’ tasks than men (e.g., analysis, design, and report editing); and (iii) women students in men-majority groups are less satisfied with several aspects of the group work than men students in the same groups. These findings add to our understanding of group dynamics and collaboration (including what to avoid and where to pay extra attention) when assigning projects in smaller groups in computing education.
ERGODIC DICHOTOMY FOR SUBSPACE FLOWS

In this paper, we obtain an ergodic dichotomy for directional flows, more generally, subspace flows, for a class of discrete sub-groups of a connected semisimple real algebraic group G , called transverse subgroups. The class of transverse subgroups of G includes all discrete subgroups of rank one Lie groups, Anosov subgroups and their relative versions. Let Γ be a Zariski dense θ -transverse subgroup for a subset θ of simple roots. Let L θ = A θ S θ be the Levi subgroup associated with θ where A θ is the central maximal real split torus and S θ is the product of a semisimple subgroup and a compact torus. There is a canonical Γ-invariant subspace ˜Ω θ of G/S θ on which Γ acts properly discontinuously. Setting Ω θ = Γ \ ˜Ω θ , we consider the subspace flow given by A W = exp W for any linear subspace W < a θ . Our main theorem is a Hopf-Tsuji-Sullivan type dichotomy for the ergodicity of (Ω θ , A W , m ) with respect to a Bowen-Margulis-Sullivan measure m satisfying a certain hypothesis. As an application, we obtain the codimension dichotomy for a θ - Anosov subgroup Γ < G : for any subspace W < a θ containing a vector u in the interior of the θ -limit cone of Γ, we have codim W ≤ 2 if and only if the A W -action on (Ω θ , m u ) is ergodic where m u is the Bowen-Margulis-Sullivan measure associated with u .
On ISS-Lyapunov functions for inﬁnite-dimensional linear control systems subject to saturations

—This article deals with the derivation of ISS-Lyapunov functions for inﬁnite-dimensional linear systems subject to saturations. Two cases are considered: 1) the saturation acts in the same space as the control space; 2) the saturation acts in another space, especially a Banach space. For the ﬁrst case, an explicit ISS-Lyapunov function can be derived. For the second case, we can only ensure the existence of an ISS-Lyapunov function.
An Evaluation of the Signal to Noise Ratio (SNR) of Next Generation Wireless Communication Systems using Large Intelligent Surfaces: Deep Learning Approach

The existing data rate must be greatly increased in order to support the numerous applications of the next generation communication systems. Using Large Intelligent Surfaces (LIS), which are a panel with mounted reflective components, is one way to address this problem. Their primary function is to divert the electromagnetic signal to the intended user. As a result, the received signal's strength and reception quality both improve, improving the Quality of Service (QoS). Machine Learning algorithms have been used to implement LIS in a number of ways, including channel estimation and the calculation of phase shifts (discrete), to mention a few. Here, it is suggested that the Signal to Noise Ratio (SNR) for a LIS-supported communication system be assessed using a Deep Learning (DL) model. On the DL model, the effects of the SGD, Adam RMSProp Adadelta and Adamax optimizers are investigated. The Mean Squared Error (MSE) loss function is taken into account. The Adam optimizer offers the highest level of precision, making it preferable to other optimizers. The SNR for 10 users is measured using the suggested DL model with Adam Optimizer. The outcomes of this work is contrasted with the SNR estimate by an existing technique that calculates SNR based on LIS size and the location of transmitter and receiver with an accuracy of 93.5%. The simulation results indicate that the accuracy is increased to 96% using the suggested DL model which attains an average error of 3.6.

Safety Concept and Partial Factors for Bridge Assessment under Military Loading

: The use of civilian bridges by military vehicles is in the NATO countries regulated and governed by STANAG 2021. This standard, however, does not fully deliver some of the essential aspects important for safe and reliable crossing of military vehicles over existing bridges. This paper aims at investigating the military loads and at developing partial factors that can be utilized during the assessment of bridges for military traffic. A number of factors must be taken into account including target reliability index and uncertainties related to dynamic amplification factor, static load due to military vehicle and applied model for load effect. The results show that the military partial factors can be generally considered in a range close to or smaller than those values given in civilian codes.
Self-efficacy in Teaching Chinese as a Foreign Language in Self-efficacy in Teaching Chinese as a Foreign Language in Australian Schools Australian Schools

: Participating in a research-oriented teacher education program, 20 university graduates from China were invited to teach Chinese as a foreign language in western Sydney schools and conducted teacher research for one and half years. By analysing their research on their own teaching through a qualitative approach, this study attempted to identify the factors that influenced their self-efficacy in teaching Chinese as a foreign language in an English-speaking school system. Influential factors identified in this research include teacher factors (proficiency in the medium of instruction, professional learning, teaching experience, and understanding of student), student factors (student responses, classroom discipline, students’ motivation, student-teacher relations, and students’ age) and contextual factors (culture, influence from other teachers, class size, and resources). Findings of this research have implications for foreign language teacher education.

The results showed that there were different qualities of beef rendang in the Darek and Pasisia regions in terms of shape, color, aroma, texture, and taste
Romantic Love and Behavioral Activation System Sensitivity to a Loved One

Research investigating the mechanisms that contribute to romantic love is in its infancy. The behavioral activation system is one biopsychological system that has been demonstrated to play a role in several motivational outcomes. This study was the first to investigate romantic love and the behavioral activation system. In study 1, the Behavioral Activation System—Sensitivity to a Loved One (BAS-SLO) Scale was validated in a sample of 1556 partnered young adults experiencing romantic love. In study 2, hierarchical linear regression was used to identify BAS-SLO Scale associations with the intensity of romantic love in a subsample of 812 partnered young adults experiencing romantic love for two years or less. The BAS-SLO Scale explained 8.89% of the variance in the intensity of romantic love. Subject to further validation and testing, the BAS-SLO Scale may be useful in future neuroimaging and psychological studies. The findings are considered in terms of the mechanisms and evolutionary history of romantic love.
