An auditory processing advantage enables communication in less complex social settings: Signs of an extreme female brain in children and adolescents being assessed for Autism Spectrum Disorders
Authors: Åkerlund Sofia , Håkansson Anders , Claesdotter-Knutsson Emma 
Published: January 2023

BackgroundThe underlying factors of the male predominance in Autism Spectrum Disorders (ASD) are largely unknown, although a female advantage in social communication has been pointed out as a potential factor. Recently, attention has been given to ASD as a sensory processing disorder, focusing on the audio-visual temporal processing paramount for the development of communication. In ASD, a deviant audio-visual processing has been noted, resulting in difficulties interpreting multisensory information. Typically Developed (TD) females have shown an enhanced language processing in unisensory situations compared to multisensory situations. We aim to find out whether such an advantage also can be seen in girls within the ASD population, and if so, is it related to social communication skills?MethodForty children (IQ &gt; 85), 20 females (mean age = 13.90 years, SD = 2.34) and 20 males (mean age = 12.15 years, SD = 2.83) triaged for an ASD assessment were recruited from a child and youth psychiatric clinic in Sweden. Using The Social Responsiveness Scale (SRS) we looked at associations with child performance on the Integrated Visual and Auditory Continuous Performance Test (IVA-2).ResultsAn auditory advantage in the female group was associated with less rated problems in social communications in unisensory processing whereas in multisensory processing an auditory dominance was associated with more rated problems in Social Awareness. In the male group, a visual dominance was associated with more rated problems in Social Rigidity.ConclusionA female unisensory processing advantage in ASD could very well be explaining the male domination in ASD. However, the social difficulties related to multisensory processing indicate that ASD females might be struggling as hard as males in more complex settings. Implications on the assessment procedure are discussed.

Osmanthus fragrans Lour. has been cultivated for more than 2500 years because of the fragrance and color of the flowers. The flowers and roots have been used in tea, liquors, foods, and traditional Chinese medicine. The species contains more than 180 compounds including terpenoids, phenylpropanoids, polyphenols, flavonoids, and sterols. However, there has been limited information available on the allelopathic properties and allelopathic substances of O. fragrans. We investigated the allelopathy and allelopathic substances of O. fragrans and Osmanthus heterophyllus (G.Don) P.S. Green, as well as Osmanthus × fortunei Carrière, which is the hybrid species between O. fragrans and O. heterophyllus. The leaf extracts of O. fragrans, O. heterophyllus, and O. × fortunei suppressed the growth of cress (Lepidium sativum L.), alfalfa (Medicago sativa L.), Lolium multiflorum Lam., and Vulpia myuros (L.) C.C.Gmel with the extract concentration dependently. The extract of the hybrid species O. × fortune was the most active among the extracts. The main allelopathic substances of O. × fortunei and O. fragrans were isolated and identified as (+)-pinoresinol and 10-acetoxyligustroside, respectively. (+)-Pinoresinol was also found in the fallen leaves of O. × fortunei. Both compounds showed an allelopathic activity on the growth of cress and L. multiflorum. On the other hand, several allelopathic substances including (+)-pinoresinol may be involved in the allelopathy of O. heterophyllus. O. fragrans, O. heterophyllus, and O. × fortunei are evergreen trees. but their senescent leaves fall and cover the soil under the trees. It is possible that those allelopathic substances are liberated through the decomposition process of the leaves into their rhizosphere soil, and that they accumulate in the soil and provide a competitive advantage to the species through the inhibition of the growth of the neighboring competing plants. Therefore, the leaves of these Osmanthus species are allelopathic and potentially useful for weed management options in some agriculture settings to reduce commercial herbicide dependency for the developing sustainable agriculture systems.

Drought has serious effects on forests, especially semi-arid and arid forests, around the world. Zagros Forest in Iran has been severely affected by drought, which has led to the decline of the most common tree species, Persian oak (Quercus brantii). The objective of this study was to determine the effects of drought on the anatomical structure of Persian oak. Three healthy and three declined trees were sampled from each of two forest sites in Ilam Forest. Discs were cut at breast height, and three sapwood blocks were taken near the bark of each tree for sectioning. The anatomical characteristics measured included fiber length (FL), fiber wall thickness (FWT), number of axial parenchymal cells (NPC), ray number (RN), ray width (RW), and number of calcium oxalate crystals. Differences between healthy and declined trees were observed in the abundance of NPC and in RN, FL, and FWT, while no differences occurred in the number of oxalate crystals. The decline had uncertain effects on the FL of trees from sites A and B, which showed values of 700.5 and 837.3 μm compared with 592.7 and 919.6 μm in healthy trees. However, the decline resulted in an increase in the FWT of trees from sites A and B (9.33 and 11.53 μm) compared with healthy trees (5.23 and 9.56 μm). NPC, RN, and RW also increased in declined individuals from sites A and B (28.40 and 28.40 mm−1; 41.06 and 48.60 mm−1; 18.60 and 23.20 μm, respectively) compared with healthy trees (20.50 and 19.63 mm−2; 31.60 and 28.30 mm−2; 17.93 and 15.30 μm, respectively). Thus, drought caused measurable changes in the anatomical characteristics of declined trees compared with healthy trees.

Na Odontologia são considerados pacientes portadores de necessidades especiais (PNEs), aqueles que precisam de serviço odontológico diferenciado. De acordo com dados epidemiológicos cerca de 24% da população brasileira apresentava algum tipo de deficiência. A Síndrome de Down (SD) é o exemplo mais evidente de PNE, também chamada de trissomia 21, definida por uma demora no progresso das funções motoras e de fala, principalmente o retardo mental. A SD pode apresentar-se em grau leve, moderada ou grave e profunda. Suas características clínicas bucais envolvem micrognatia, língua fissurada, palato estreito alto e ogival, anodontias, modificação na sequência de erupção dentária, entre outros. Restaurações que utilizam técnicas do tipo indiretas exibem uma grande vantagem no atendimento odontológico para pacientes com deficiências, pois proporcionam um procedimento menos traumático. Desta forma o trabalho tem como objetivo relatar um caso clínico de Tratamento restaurador do tipo onlay em um paciente portador de Síndrome de Down. Paciente de gênero masculino, 38 anos, portador de SD, procurou a clínica-escola do curso de Odontologia do Centro Universitário Fametro apresentando como queixa principal “Quero fazer a troca da prótese pois já passou muito tempo de uso, e fazer restauração”. Ao realizar o exame intraoral, observou-se uma extensa restauração insatisfatória em resina composta nas faces mésio-oclusal (classe II) do elemento 16, nesse sentido optou-se substituí-la por uma restauração indireta do tipo onlay. Diante do presente relato de caso, constatou-se a importância do manejo diferenciado ao paciente PNE, para que haja uma adequada devolução da função anatômica e oclusal, nesse sentido cabe ao profissional cirurgião- dentista se atentar às peculiaridades de cada paciente para executar medidas corretas,proporcionado uma melhor qualidade de vida ao indivíduo.

Abstract
We propose and demonstrate an experimental method to evaluate spin-transfer-torque (STT) efficiency in current-perpendicular-to-plane giant magnetoresistance devices, which utilizes STT-induced magnetization reversal against a perpendicular magnetic field. Using this method, we estimated the STT efficiency of FeCr with negative spin polarization, which attracts attention in spintronics applications. In comparison with NiFe with positive spin polarization, the sign of the STT induced by FeCr was opposite, reflecting the negative spin polarization. The STT efficiency of FeCr was approximately half that of NiFe at room temperature and surpassed that of NiFe at 50 K.

<p> Classification, segmentation, and the identification of the infection region in MRI images of brain tumors are labor-intensive and iterative processes. Numerous anatomical structures of the human body may be envisioned using an image processing theory. With basic imaging methods, it is challenging to see the aberrant human brain's structure. The neurological structure of the human brain may be distinguished and made clearer using the magnetic resonance imaging technique. The MRI approach uses a number of imaging techniques to evaluate and record the human brain’s interior features. In this study, we focused on strategies for noise removal, gray-level co-occurrence matrix (GLCM) extraction of features, and segmentation of brain tumor regions based on Discrete Wavelet Transform (DWT) to minimize complexity and enhance performance. In turn, this reduces any noise that could have been left over after segmentation due to morphological filtering. Brain MRI scans were utilized to test the accuracy of the classification and the location of the tumor using probabilistic neural network classifiers. The classifier's accuracy and position detection were tested using MRI brain imaging. The efficiency of the suggested approach is demonstrated by experimental findings, which showed that normal and diseased tissues could be distinguished from one another from brain MRI scans with about 100% accuracy. </p>
Singularity-Robust Full-Pose Workspace Control of Space Manipulators with Non-Zero Momentum
Authors: Rousso Patrick , Chhabra Robin 
Published: January 2023

<p> We address the end-effector full-pose tracking control problem in free-floating space manipulators, experiencing constant non-zero linear and angular momentum. The aim is to develop an output-tracking (workspace) control law free of singularities due to parameterizing the end-effector motion and being robust against singularities of the input-output decoupling matrix (generalized Jacobian matrix). Space manipulators are modelled as open-chain multi-body systems with single- and multidegree-of-freedom joints, whose kinematics and dynamics are formulated on the Special Euclidean group SE(3). Such systems exhibit conserved (not necessarily zero) total momentum when operating in the free-floating regime, which we use to systematically reduce their dynamical equations by eliminating the base spacecraft’s motion. To avoid parameterizing the end-effector motion, we consider its full pose as the system output and develop a novel feedback linearization technique on the matrix Lie group SE(3) in the reduced phase space of the space manipulator. We then propose an intrinsic feedforward, feedback proportional-integral-derivative workspace controller involving a coordinate-free pose error function on SE(3) and velocity error on its Lie algebra. Using a Lyapunov candidate, this controller is proven to stabilize the end-effector pose to a feasible desired trajectory. The input-output decoupling matrix in the proposed control law can lose rank at some regions of the configuration space; hence, we implement a singularity-robust inverse, derived from the damped least squares method, to avoid impractical joint torques in these regions. The developed controller is implemented on a 7-degree-of-freedom manipulator onboard a spacecraft and its efficacy and robustness are demonstrated trough series of simulations. </p>
Low Order Response Model-based Secondary Control for the AC-MTDC Grids
Authors: Ancha Satish Kumar 
Published: January 2023

<p>The holistic nature of primary and secondary control leads to the satisfactory operation of the AC surrounded Multi-Terminal HVDC (AC-MTDC) grids. In this paper, a Lower Order Response Model (LORM) is developed and utilized in the hierarchical control structure. The LORM based secondary control is proposed while operating primary control in droop for a requisite operation of the AC-MTDC grids. The objective of this secondary control is to ensure reduced frequency and DC-voltage deviation with enhanced stability of the AC-MTDC grids. Further, the stability margins of the AC-MTDC grid are identified by employing an eigenvalue analysis of the LORM. These margins decide the droop value limits, which are utilized in secondary control for the stable operation of the AC-MTDC grid. The proposed framework is validated in MATLAB and PSCAD/EMTDC co-simulation platforms while considering two case studies and an AC-MTDC test system consisting of five terminals integrated into a two-area power system.</p>

Piezoelectric is a micro-scale energy harvesting device that converts mechanical energy into electrical energy. When there is a collision with the piezoelectric material, it will cause vibration and produce stress and deflection. This study aims to determine the effect of the shape of the cross section of the bluff body on the electric voltage generated by the piezoelectric. This research method is to observe the piezoelectric vibrating due to the flow of air that passes through the cross section of the bluff body to produce an electric voltage. The independent variables in this study were the shape of the bluff body, and the speed of the wind flow. Where the dimensions and height in one cross-section of the square bluff body, rhombus, and triangle have the same size, which is 7 cm. The wind speed used is 5 m/s, 7 m/s, and 9m/s. The research was conducted in a wind tunnel and the cross-sectional distance between the bluff body to the piezoelectric is 80 cm. The result of the variable cross-sectional shape of the bluff body that produces the highest electrical voltage is the rhombic bluff body cross-section. The result of the speed variable that produces the highest electrical voltage, which is at a speed of 9 m/s, produces an electric voltage of 5.58 volts across the body of the kept cliff. Due to the oscillations, the fins move up and down to hit the piezoelectric.
