State space models meet transformers for hyperspectral image classification

In recent years, convolutional neural networks and vision transformers have emerged as predominant models for hyperspectral remote sensing image classification task, leveraging staked convolution layers and self-attention mechanisms with high computation costs, respectively. Recent studies, such as the Mamba model, have showcased the ability of state space model (SSM) with efficient hardware-aware designs in efficiently modeling sequences and extracting implicit features along tokens, which is precisely needed for accurate hyperspectral image (HSI) classification. Thus making SSM-based model potentially a new architecture for remote sensing HSI classification task. However, SSM encounters challenges in modeling HSI due to the insensitivity of spatial information and redundant spectral characteristics. Given SSM-based methods rarely explored in HSI classification, in this work, we present the first exploration of SSM-based models for HSI classification task. Our proposed method MamTrans effectively leverages the capacity of transformer for capturing spatial tokens relationships and Mamba for extracting implicit features along tokens. Besides, we propose a Bidirectional Mamba Module to enhance SSM’s spatial perception ability of extracting spatial features in HSI. Our proposed MamTrans obtains a new state-of-the-art performance across five commonly employed HSI classification benchmarks, demonstrating the robust generalization of MamTrans and effectiveness of SSM-based structure for HSI classification task.

Analysis of Students' Spatial Abilities Reviewed From Gender Differences In Class X

Spatial skills are important for studying geometric shapes. People who have good spatial abilities can easily imagine objects in three dimensions. Factors that influence differences in student abilities include gender differences. The aim of this research is to describe students' spatial abilities in terms of gender differences. The type of research used is quantitative-qualitative research. Spatial ability test results data are calculated and presented in quantitative form and analyzed qualitatively. This research was conducted at SMA Negeri 3 Ambon class X Science 1 with a total of 36 students consisting of 12 male students and 24 female students. In determining the subject of this research, a purposive sampling technique was used, namely taking data sources with certain considerations. The research subjects selected to be interviewed were 6 students with the assessment criteria for spatial ability test questions consisting of 1 male student and 1 female student with high spatial ability, 1 male student and 1 female student with moderate spatial ability, and 1 male student with moderate spatial ability. male and 1 female student with low spatial abilities. The largest percentage of student test results are in the low category. Based on the results of the spatial ability test, it shows that in the element of spatial perception, male subjects are more likely to meet the indicators of the ability to identify objects vertically and horizontally even though the position of the object is manipulated. Meanwhile, female subjects tend to use their spatial abilities as indicators of the ability to distinguish lines, horizontal and vertical planes in spatial figures. In the spatial visualization element, male subjects are more likely to fulfill the indicators than female subjects regarding stacks of unit cubes whose position or shape has been manipulated and visualizing stacks of unit cubes from more than one point of view. For the element of mental rotation, male subjects tend to be more capable than female subjects of rotating, imagining rotation and describing a flat shape or spatial structure correctly after rotation. However, elements of spatial orientation of female subjects are more likely to determine the appearance of objects from different perspectives than male subjects. In the spatial relations element, male subjects are more likely to determine the relationship of an object with other objects than female subjects.

Polystyrene nanoplastics induced learning and memory impairments in mice by damaging the glymphatic system

The excessive usage of nanoplastics (NPs) has posed a serious threat to the ecological environment and human health, which can enter the brain and then result in neurotoxicity. However, research on the neurotoxic effects of NPs based on different exposure routes and modifications of functional groups is lacking. In this study, the neurotoxicity induced by NPs was studied using polystyrene nanoplastics (PS-NPs) of different modifications (PS, PS-COOH, and PS-NH2). It was found that PS-NH2 through intranasal administration (INA) exposure route exhibited the greatest accumulation in the mice brain after exposure for 7 days. After the mice were exposed to PS-NH2 by INA means for 28 days, the exploratory ability and spatial learning ability were obviously damaged in a dose-dependent manner. Further analysis indicated that these damages induced by PS-NH2 were closely related to the decreased ability of glymphatic system to clear β-amyloid (Aβ) and phosphorylated Tau (P-Tau) proteins, which was ascribed to the loss of aquaporin-4 (AQP4) polarization in the astrocytic endfeet. Moreover, the loss of AQP4 polarization might be regulated by the NF-κB pathway. Our current study establishes the connection between the neurotoxicity induced by PS-NPs and the glymphatic system dysfunction for the first time, which will contribute to future research on the neurotoxicity of NPs.

Spatial attention inference model for cascaded siamese tracking with dynamic residual update strategy

Target representation is crucial for visual tracking. Most Siamese-based trackers try their best to establish target models by using various deep networks. However, they neglect the exploration of correlation among features, which leads to the inability to learn more representative features. In this paper, we propose a spatial attention inference model for cascaded Siamese tracking with dynamic residual update strategy. First, a spatial attention inference model is constructed. The model fuses interlayer multi-scale features generated by dilation convolution to enhance the spatial representation ability of features. On this basis, we use self-attention to capture interaction between target and context, and use cross-attention to aggregate interdependencies between target and background. The model infers potential feature information by exploiting the correlations among features for building better appearance models. Second, a cascaded localization-aware network is introduced to bridge a gap between classification and regression. We propose an alignment-aware branch to resample and learn object-aware features from the predicted bounding boxes for obtaining localization confidence, which is used to correct the classification confidence by weighted integration. This cascaded strategy alleviates the misalignment problem between classification and regression. Finally, a dynamic residual update strategy is proposed. This strategy utilizes the Context Fusion Network (CFNet) to fuse the templates of historical and current frames to generate the optimal templates. Meanwhile, we use a dynamic threshold function to determine when to update by judging the tracking results. The strategy uses temporal context to fully explore the intrinsic properties of the target, which enhances the adaptability to changes in the target’s appearance. We conducted extensive experiments on seven tracking benchmarks, including OTB100, UAV123, TC128, VOT2016, VOT2018, GOT10k and LaSOT, to validate the effectiveness of our proposed algorithm.

Spatial Thinking and Movements in Geometry: GeoGebra with a focus on building animated scenarios

Animated Scenarios are constructions created in GeoGebra with mathematical elements and movement, constituting an animated scene. Movement is fundamental to the construction of Animated Sceneries, it is also essential to spatial thinking and spatial abilities. This theoretical essay aims to discuss the potential of building Animated Scenarios in GeoGebra in/for the recognition of flat and spatial geometric objects, articulated with the movements associated with spatial thinking. For this, the House Animated Scenario are considered. Thus, we identified that movements performed during this construction allow rotating and modifying the shape of objects and that these movements are related to spatial abilities. Furthermore, the use of these movements in construction contributes to the recognition of important characteristics that distinguish flat and spatial objects.

Psychological Characteristics of Children with Attention Deficit Hyperactivity Disorder as a Cause of Their Stigmatization and Victimization in Society

The psychological characteristics of children with attention deficit hyperactivity disorder (ADHD) are a significant barrier to their adaptation to society and the realization of their personal potential. There is a shortage of literature reviews on this topic, taking into account research over the past few years on. The basis for the literature review material was 51 foreign sources (of which 100% of the sources were in the last four years from 2020 to 2024, with 21 (41%) sources in 2024). Methods of comparative analysis and synthesis were used in writing the literature review. Modern literature indicates the presence of a complex of psychological characteristics in children with ADHD, which are based on disorders in the cognitive, emotional-volitional and behavioral spheres. In the cognitive sphere of children with ADHD, there are impairments in spatial abilities, decreased working memory, attention deficit and low speed of information processing, which are the cause of specific learning disabilities in more than half of children with ADHD. The most common emotional disturbances in children with ADHD are abnormal symptoms of anxiety, stress, low mood, motivation, and depression. Common behavioral symptoms of ADHD include impulsivity, irritability, suicidal behavior, and deliberate attempts at non-suicidal self-harm. All of these cognitive, emotional and behavioral characteristics of children with ADHD can act as predictors of external stigma, most often expressed by school bullying (victimization), as well as internal stigmatization (low self-esteem). Horse riding, music therapy, group psychodrama, training in magic tricks, etc. are cited as the main modern non-pharmacological means of correcting the symptoms of ADHD.

Differential role of NMDA receptors in hippocampal-dependent spatial memory and plasticity in juvenile male and female rats.

Early life, or juvenility, stands out as the most pivotal phase in neurodevelopment due to its profound impact over the long-term cognition. During this period, significant changes are made in the brain's connections both within and between different areas, particularly in tandem with the development of more intricate behaviors. The hippocampus is among the brain regions that undergo significant postnatal remodeling, including dendritic arborization, synaptogenesis, the formation of complex spines and neuron proliferation. Given the crucial role of the hippocampus in spatial memory processing, it has been observed that spatial memory abilities continue to develop as the hippocampus matures, particularly before puberty. The N-methyl-d-aspartate (NMDA) type of glutamate receptor channel is crucial for the induction of activity-dependent synaptic plasticity and spatial memory formation in both rodents and humans. Although extensive evidence shows the role of NMDA receptors (NMDAr) in spatial memory and synaptic plasticity, the studies addressing the role of NMDAr in spatial memory of juveniles are sparse and mostly limited to adult males. In the present study, we, therefore, aimed to investigate the effects of systemic NMDAr blockade by the MK-801 on spatial memory (novel object location memory, OLM) and hippocampal plasticity in the form of long-term potentiation (LTP) of both male and female juvenile rats. Our results show the sex-dimorphic role of NMDAr in spatial memory and plasticity during juvenility, as systemic NMDAr blockade impairs the OLM and LTP in juvenile males without an effect on juvenile females. Taken together, our results demonstrate that spatial memory and hippocampal plasticity are NMDAr-dependent in juvenile males and NMDAr-independent in juvenile females. These sex-specific differences in the mechanisms of spatial memory and plasticity may imply gender-specific treatment for spatial memory disorders even in children.

Primary Student Spatial Reasoning Abilities: Progression and Challenges

Primary Student Spatial Reasoning Abilities: Progression and Challenges

The role of formal schooling in the development of children's reading and arithmetic white matter networks.

Children's white matter development is driven by experience, yet it remains poorly understood how it is shaped by attending formal education. A small number of studies compared children before and after the start of formal schooling to understand this, yet they do not allow to separate maturational effects from schooling-related effects. A clever way to (quasi-)experimentally address this issue is the longitudinal school cut-off design, which compares children who are similar in age but differ in schooling (because they are born right before or after the cut-off date for school entry). We used for the first time such a longitudinal school cut-off design to experimentally investigate the effect of schooling on children's white matter networks. We compared "young" first graders (schooling group, n=34; Mage=68 months; 20 girls) and "old" preschoolers (non-schooling group, n=33; Mage=66 months; 18 girls) that were similar in age but differed in the amount of formal instruction they received. Our study revealed that changes in fractional anisotropy and mean diffusivity in five a priori selected white matter tracts during the transition from preschool to primary school were predominantly driven by age-related maturation. We did not find specific schooling effects on white matter, despite their strong presence for early reading and early arithmetic skills. The present study is the first to disentangle the effects of age-related maturation and schooling on white matter within a longitudinal cohort of 5-year-old preschoolers. RESEARCH HIGHLIGHTS: White matter tracts that have been associated with reading and arithmetic may be susceptible to experience-dependent neuroplasticity when children learn to read and calculate. This longitudinal study used the school cut-off design to isolate schooling-induced from coinciding maturational influences on children's white matter development. White matter changes during the transition from preschool to primary school are predominantly driven by age-related maturation and not by schooling effects. Strong effects of schooling on behavior were shown for early reading and early arithmetic, but not for verbal ability and spatial ability.

Complex dynamics in nonlinear small time-delayed optoelectronic oscillator and application in fast reservoir computing and pulse generation

We investigated a time-delayed optoelectronic oscillator (OEO) that displays a wide range of complex dynamic behavior under small time delay. The phase-space trajectory distributions in different dynamic regimes were compared which brings a new perspective on the underlying mechanism of the transition process. It was found that bifurcation is always possible no matter how small the time delay is even if the universal adiabatic approximation model is invalid. Hereby we proposed a versatile simple oscillator which has a potential capacity as memory carrier and high-dimensional state spatial mapping ability that brings 1000 times computing-efficiency improvements of reservoir computing over the large time delay one. Furthermore, we demonstrated a new approach for a tunable optoelectronic pulse generator (repetition rate at 0.2 MHz and 0.25 GHz) which depends critically on time-delayed input electrical pulse. The proposed oscillator is also a promising system for the applications of fast chaos-based communication.

Topical application of daphnetin hydrogel for traumatic brain injury.

Traumatic brain injury (TBI) causes neuronal cell damage and dysfunction. According to previous studies, daphnetin (Dap) has a protective effect in neurological injury. However, the in vivo bioavailability of daphnetin is not high. The purpose of this study was to determine whether administering daphnetin directly into the site of injury via a hydrogel drug carrier could improve its therapeutic impact. Tripolycerol monostearates / daphnetin (TM/Dap) hydrogels were prepared and characterised using water bath heating, scanning electron microscopy (SEM) and small animal in vivo imaging techniques. The TBI model was established using the Feeney free fall impact method. Using the Morris water maze test, the mNSS neurological deficit rating scale, haematoxylin-eosin staining, and liver and kidney function tests, the therapeutic benefit of TM/Dap and its toxic side effects were assessed. The therapeutic effects of TM/Dap were further investigated using wet and dry gravimetric methods, Evans blue staining, protein immunoblotting, immunofluorescence staining techniques and ELISA. The efficacy of the TM/Dap hydrogel in gradually releasing daphnetin in the context of traumatic brain damage was shown by both in vitro and in vivo tests. Behavioral experiments showed that the learning and spatial memory abilities of TM/Dap hydrogel treated mice were significantly improved in the water maze experiment. And TM/Dap hydrogel has high biosafety for organisms. The results of the therapeutic mechanism of action showed that TM/Dap hydrogel showed more significant efficacy in reducing the neuroinflammatory response caused by TNF-α, IL-6 and other factors, as well as promoting the recovery of post-traumatic neurological function. The use of hydrogel as a drug carrier for daphnetin showed more significant efficacy in reducing neuroinflammatory response, protecting nerve tissue and promoting post-traumatic neurological recovery compared with traditional drug delivery methods.

Investigating the Impact of the AI-Supported 5E (AI-s5E) Instructional Model on Spatial Ability.

Improving students' spatial abilities is an important goal in education. Spatial ability is a skill needed in many fields, such as science, mathematics, engineering, and architecture. Since this ability can be improved through training, this study adopted a quasi-experimental design to investigate the effects of an artificial intelligence-supported 5E (AI-s5E) instructional model on students' spatial visualization, spatial relationships, and spatial orientation performances that explain their spatial abilities. A total of 43 students from two classes at a secondary school in western Turkey were recruited to participate in this study. One of the classes was the experimental group (f = 23), which adopted the AI-s5E approach, and the other class was the control group (f = 20), which adopted the traditional teaching model. The results showed that the integration of the AI-s5E instructional approach into education improved students' spatial abilities and sub-dimensions. In light of the findings, it can be recommended that AI applications, which have a positive and significant impact on spatial skills, can be integrated into teachers' lessons and even included in curriculum programs.

Instructional Practices by Engineering Graphics and Design Teachers: A Focus on Teaching and Learning of Isometric Drawing

This qualitative study was conducted to investigate the instructional practices used by Engineering Graphics and Design (EGD) to teach Isometric Drawing (ID). This enquiry was necessitated by the growing concern from subject advisors and teachers about the poor performance of learners in isometric drawing. In an attempt to meet the objectives, this study adopted an interpretivist position to understand the instructional practices employed by teachers in teaching isometric drawing. This study used seven (7) EGD teachers who were conveniently selected, it is worth noting that the sample was influenced by the fact that EGD is a subject that is not common hence not many schools offer it. Data was collected through semi-structured interviews and was analyzed using a thematic analysis. Pedagogical Content Knowledge (PCK) was used as a framework that underpinned this study. Findings from this study indicated that all EGD teachers have the common understanding that ID involves converting 2d orthographic view into a 3d figure. The findings further revealed that teachers rely heavily on models, YouTube videos and AutoCAD to develop learners’ spatial ability which is a very important skill. The study recommended that there should be no teacher hired to teach EGD without being fully trained. The study further recommended that future research should be conducted on learners to get their insight on why they are performing poorly in ID.

Experimental insights into cognition, motor skills, and artistic expertise in Paleolithic art

The production of Paleolithic art represents one of the most intricate technical and cognitive endeavors of Homo sapiens, marked by its profound antiquity and vast temporal and spatial framework. Despite its significance, there have been no prior studies aimed at understanding the cognitive and motor skills linked to the creation of realistic images characteristic of this artistic cycle. This research integrates archaeology and experimental psychology, premised on the assumption that the neurological basis of Anatomically Modern Humans has not changed substantially since the Upper Paleolithic. This work employs an innovative interdisciplinary approach, utilizing psychometric tests and drawing and engraving tasks monitored by motion-sensing gloves, to compare the performance of experts and non-experts in visual arts when faced with challenges akin to those of Upper Paleolithic artistic production. The results revealed that expertise in visual arts is linked to enhanced spatial abilities and specific patterns in drawing from memory. Additionally, both experts and non-experts displayed similar motor skills when engraving using Paleolithic techniques, suggesting that these techniques required specialized training in the contemporary experts. In conclusion, this research deepens our understanding of the processes involved in Upper Paleolithic artistic production.

Exploring the Role of Geometry Understanding and Spatial Ability in Academic Achievement: The Moderating Effect of Self-Confidence

This study investigates the impact of understanding geometry concepts, spatial ability, and self-confidence on student learning outcomes. Understanding geometry enhances mathematical logic, spatial ability strengthens spatial comprehension, and self-confidence boosts learning motivation. Collectively, these variables are crucial for improving student learning outcomes. The research employed an explanatory design, conducted in two elementary schools within the same cluster. A random sampling method selected samples from one class of an Elementary School in Panyikokkang with 21 students and another class with 23 students, resulting in a total of 44 students. Data collection instruments included a validated Self-Confidence questionnaire, Geometry Concept Understanding test, Spatial Ability test, and a Student Learning Outcomes test derived from daily quizzes on geometry topics. Data were analyzed using Inferential Statistical Analysis and Moderated Regression Analysis (MRA). The Moderated Regression Analysis (MRA) revealed that self-confidence acts as a quasi-moderator in the relationship between understanding geometry concepts and learning outcomes. Specifically, students with higher self-confidence showed a better understanding of geometry concepts, positively influencing their learning outcomes. However, self-confidence did not moderate the effect of spatial ability on learning outcomes. These findings highlight the importance of understanding geometry concepts in enhancing students' comprehension of geometry and developing spatial abilities at the elementary level. The results suggest that self-confidence plays a significant role in mediating the relationship between understanding geometry concepts and learning outcomes but not between spatial ability and learning outcomes. The study underscores the necessity for educators to focus on understanding geometry concepts and fostering self-confidence to design effective learning strategies that improve student achievement in mathematics, particularly in geometry.

Electrospun polycaprolactone-chitosan nanofibers on a zinc mesh as biodegradable guided bone-regeneration membranes with enhanced mechanical, antibacterial, and osteogenic properties for alveolar bone-repair applications

Guided bone-regeneration membrane (GBRM) is commonly used in bone-repair surgery because it blocks fibroblast proliferation and provides spatial support in bone-defect spaces. However, the need for removal surgery and the lack of antibacterial properties of conventional GBRM limit its therapeutic applicability for alveolar bone defects. Here we developed a GBRM for alveolar bone-repair and -regeneration applications through double-sided electrospinning of polycaprolactone and chitosan layers on a Zn mesh surface (denoted DSZM). The DSZM showed a UTS of ∼25.6 MPa, elongation of ∼16.1%, strength-elongation product of ∼0.413 GPa%, and ultrahigh spatial maintenance ability, and the UTS was over 6 times higher than that of commercial Bio-Gide membrane. The DSZM exhibited a corrosion rate of ∼17 µm/y and a Zn ion concentration of ∼0.23 µg/ml after 1 month of immersion in Hanks’ solution. The DSZM showed direct and indirect cytocompatibility with exceptional osteogenic differentiation and calcium deposition toward MC3T3-E1 cells. Further, the DSZM showed strongly sustained antibacterial activity against S. aureus and osteogenesis in a rat critical-sized maxillary defect model. Overall, the DSZM fits the requirements for alveolar bone-repair and -regeneration applications as a biodegradable GBRM material due to its spatial support, suitable degradability, cytocompatibility, and antibacterial and osteogenic capabilities. Statement of significanceThis work reports the mechanical properties, antibacterial ability and osteogenic properties of electrospun PCL-CS nanofiber on Zn mesh as biodegradable guided bone-regeneration membrane for alveolar bone-repair applications. Our findings demonstrate that the DSZM prepared by double-sided electrospinning of PCL-CS layers on Zn mesh showed a UTS of ∼25.6 MPa, elongation of ∼16.1%, strength-elongation product of ∼0.413 GPa%, and ultrahigh spatial maintenance ability, and the UTS was over 6 times greater than that of commercial Bio-Gide® membrane. The DSZM showed direct and indirect cytocompatibility with exceptional osteogenic differentiation and calcium deposition toward MC3T3-E1 cells. Further, the DSZM showed strongly sustained antibacterial activity against S. aureus and osteogenesis in a rat critical-sized maxillary defect model.

Omaveloxolone Ameliorates Cognitive Deficits by Inhibiting Apoptosis and Neuroinflammation in APP/PS1 Mice.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease associated with aging, characterized by progressive cognitive impairment and memory loss. However, treatments that delay AD progression or improve its symptoms remain limited. The aim of the present study was to investigate the therapeutic effects of omaveloxolone (Omav) on AD and to explore the underlying mechanisms. Thirty-week-old APP/PS1 mice were selected as an experimental model of AD. The spatial learning and memory abilities were tested using the Morris water maze. Amyloid-beta (Aβ) deposition in the brains was measured using immunohistochemistry. Network pharmacological analyses and molecular docking were conducted to gain insights into the therapeutic mechanisms of Omav. Finally, validation analyses were conducted to detect changes in the associated pathways and proteins. Our finding revealed that Omav markedly rescued cognitive dysfunction and reduced Aβ deposition in the brains of APP/PS1 mice. Network pharmacological analysis identified 112 intersecting genes, with CASP3 and MTOR emerging as the key targets. In vivo validation experiments indicated that Omav attenuated neuronal apoptosis by regulating apoptotic proteins, including caspase 3, Bax, and Bcl-2. Moreover, Omav suppressed neuroinflammation and induced autophagy by inhibiting the phosphorylation of mTOR. These findings highlight the therapeutic efficacy of Omav in AD and that its neuroprotective effects were associated with inhibiting neuronal apoptosis and regulating neuroinflammation.

Towards neuroadaptive navigation assistance to reduce spatial de-skilling

Maps have been invaluable navigation aids for millennia and thus have been critical for human survival. The increasing popularity of and high dependence on digital, location-aware assistive navigation technology, however, has been shown to divert our attention from the environment and to negatively influence innate spatial abilities. To mitigate this, neuroadaptive mobile geographic information displays (namGIDs) are proposed that respond in real-time to navigators’ cognitive task demands and wayfinder’s situated visuo-spatial attention needs. In doing so, namGIDs may not only help navigators maintain navigation efficiency but more importantly, also continuously scaffold spatial learning. To do this, the proposed navigation assistance must strike the appropriate balance between welcomed mobility efficiency gains while limiting human spatial deskilling. Leveraging neuroadaptive cartography, we can ensure to remain effective navigators, empowered to explore the world with confidence.

Pengelompokan Tingkat Pengembangan Bakat pada Anak Menggunakan Metode Clustering

Education is one measure of success or success in the knowledge/intelligence of students with their talents. Talent is an innate potential ability, which still needs to be honed and retrained so that it can become a capable ability, expertise and skills. Talent can be obtained from several ability tests that will be carried out so that children can find out what talents they have. MIS Mutia Rahma is a school that plays an important role in developing the talents of each of its students with various standards from the lowest to the highest. This school strives to maximize the potential of its students. Based on data obtained from 2010-2022, there are 1056 student talent development data. However, from this data it is not yet clear how the process of dividing groups and monitoring student talents is carried out. Therefore, an effective method is needed to process this data in order to classify the development of children's talents. The method that can be used to group data on children's talent development is the K-Means algorithm. Of the 20 data, there are 3 groups, namely group 1 has 7 data and group 2 has 11 data, and group 3 has 2 data with the most results obtained being cluster 2 with the group level of talent development in children aged (X) 8-10 years, who have the ability (Y) linguistic ability (KL), musical ability (KM), spatial ability (KS), kinesthetic ability (KK) & intrapersonal ability (KIP), the type of extracurricular (Z) that is developed in children is Football.
