Practical deflection analysis of tubular telecommunication towers subjected to a temperature gradient
Authors: Król P A 
Published: October 2022

Abstract
The subject of the paper are tubular telecommunication towers, commonly used by mobile telephony operators to build relay stations placed at relatively short distances from each other. The advantage of this type of facilities is their simple structure and small surface area they occupy. It has been observed that during operation, as a result of solar radiation, the towers experience excessive deflection, resulting in disturbances in the operation of transmitting and receiving systems mounted on the towers. The issue of a reliable and relatively precise assessment of the phenomenon of uneven heating of the body surface due to sunlight is not a trivial issue. From a practical view-point, the greatest difficulty is to estimate the temperature to which the surface of a structure exposed to sunlight heats up. Even the attempts at numerical modeling of the phenomenon do not accurately reflect its essence. The paper presents a proposal of a simplified analytical computational model that allows for a practical and uncomplicated estimation of the thermal loads to which such structures are subjected as a result of insolation. The considerations were supplemented with examples from engineering practice, showing the differences in deflection of structures protected by zinc and paint coatings.

Abstract
Numerous factors may disrupt pavement construction including human errors and unforeseen changes in the environmental conditions. These incidents can shorten pavement life span. New technologies recently came to the aid of contractors and road agencies to detect and possibly mitigate undesirable impacts of unpredictable incidents during the asphalt paving process as well as monitoring pavement performance during pavements service life. In this study, several technologies including layer thickness assessment (using both MIT-scan device coupled with metal plates and conventional topographical technique), infrared thermal camera, intelligent roller compactors, and density gauge devices were utilized to develop a coherent construction system and improve the durability of asphalt pavements in Antwerp, Belgium. The data collected in situ were compared with the characterized cores in the laboratory. It was clear that several factors can influence the outcome of the employed devices. For instance, surface temperatures obtained from an infrared camera fluctuated when the camera tilted from the perpendicular axis. Such discrepancies may be associated with the changes in the distance and environmental condition that affect the refraction of the infrared spectra. It was also found that an elaborated data collection format is essential to clearly understand the correlations between the results of the employed technologies.

Published: October 2022

AbstractAs a result of changes in social, economic, and political relations, undesirable phenomena are created that have an adverse effect on the urban environment. Surface runoff represents one of several risks to environmental policy, causing the major problem in urban agglomerations. In an urbanized area, it causes an increased runoff volume and the flood peak. Also, it affects increasing the contamination of urban rainwater. The significant problem of surface runoff formation in urban river basins is the accumulation of pollutants on the surface of paved areas during the rainless period. In the case of the formation of surface runoff, these substances come into movement. It is assumed that the most polluted rainwater is in the initial phase of runoff formation. However, not all authors agree with the statement. In some literature, this phenomenon is termed the first flush. Given the above facts, the study focuses on surface runoff characteristics in terms of its quality and quantity in the initial phase of surface runoff formatting. The study aims to summarize and compare the results of several studies to evaluate the first rainwater flush in an urbanized area.

Published: October 2022

Abstract
In this study, electrospun α-mangosteen–chitosan–polyethylene oxide (PEO) nanofibers were produced via electrospinning process. The structure and morphology of nanofibers were evaluated through a field emission scanning electron microscope (FESEM) and Fourier-transform infrared (FTIR) spectroscopy. The FE-SEM demonstrated that the average diameter of electrospun α-mangosteen–chitosan–PEO nanofibers were 125.5 ± 33.6 nm, 91.8 ± 27.1 nm, and 111.7 ± 39.8 nm for 0.025, 0.05, and 0.075% (w/v) α-mangosteen concentration, respectively, meanwhile the average diameter of electrospun chitosan–PEO nanofibers and electrospun α-mangosteen–PEO nanofibers was 124.8 ± 52.8 nm and 153.5 ± 49 nm, respectively. The FE-SEM image of electrospun α-mangosteen–chitosan–PEO nanofibers shows that the higher concentration of PEO resulted in smooth morphology, no beads, and continuous fibers. The morphology of electrospun α-mangosteen–chitosan–PEO nanofibers resulted in a better preservative than the morphology of electrospun α-mangosteen–PEO nanofibers. The FTIR spectra of the electrospun nanofibers demonstrate the presence of characteristic peaks of α-mangosteen, chitosan, and PEO and indicate intermolecular interactions via hydrogen bonds. The average diameter of the electrospun α-mangosteen–chitosan–PEO nanofibers are within the size range of the extracellular matrix of the natural structure. Therefore, the electrospun α-mangosteen–chitosan–PEO nanofibers are the potential for biomedical applications.

Abstract
Lithium salts govern important characteristics of lithium-ion batteries, including their efficiency (ion conductivity), operating voltage (potential window), and thermal stability. Herein, a series of lithium borates (lithium difluoro(perfluoropinacolato)borate (PFP-F2), lithium difluoro(2-hydroxy-3,3,3,3ʹ,3ʹ,3ʹ-hexafluoroisobutirato)borate (HHIB-F2), lithium (perfluoropinacolato)(oxalato)borate (PFP-Ox), lithium bis(2-hydroxy-3,3,3,3ʹ,3ʹ,3ʹ-hexafluoroisobutirato)borate (HHIB2), and lithium (2-hydroxy-3,3,3,3ʹ,3ʹ,3ʹ-hexafluoroisobutirato)(oxalato)borate) containing CF3 and C=O groups were developed as potential electrolytes for lithium-ion batteries. The proposed lithium borates were synthesized in good purity from lithium tetrafluoroborate and lithium difluoro(oxalato)borate using trimethylchlorosilane and three types of bidentate ligands in ethylmethylcarbonate. The applicability of the novel lithium borates as electrolytes for lithium-ion batteries was demonstrated based on thermal and electrochemical stability evaluations. In addition, lithium borates with >4 CF3 groups (PFP-F2, PFP-Ox, and HHIB2) exhibited outstanding stability against hydrolysis (water contamination). HHIB-F2 showed the best ionic conductivity owing to the balanced incorporation of increased Li+ dissociation and mobility by introducing the CF3 group and reducing the anion size. HHIB-F2 and HHIB2-containing electrolytes showed better cycle performance than their conventional BF4 counterparts. This study suggests that the new lithium borates, HHIB2, and HHIB-F2, are promising lithium salts for lithium-ion batteries, providing a new direction for the lithium salt molecular design.

Abstract
Metal exsolution is a dynamic process driven under a reducing atmosphere and at elevated temperatures that results in the self-assembly of nanoparticles at the surface of complex perovskite catalysts. The nanoparticle characteristics of metal exsolution catalysts can be subject to considerable inhomogeneity, and the anisotropic surface properties of ceramic oxides have been identified to have a major influence on the exsolution behavior. We systematically reveal the orientation-dependent anisotropy of the exsolution behavior of Ni in SrTi0.9Nb0.05Ni0.05O3−δ using multi-faceted epitaxial thin films that represent a material system with properties in between functional ceramics and single-crystalline perovskite thin film model systems. Using an approach of combined orientation mapping and surface imaging we study the exsolution behavior with particular focus on the initial exsolution response, i.e. after short annealing times. We find orientation-specific variations in the surface morphology of the thin film facets. In the as-prepared state, surface reconstructions cause the formation of patterned surface structures for all thin film facets apart from (001) surfaces, which exhibit a plain surface morphology as well as an enhanced exsolution response. Surface reconstructions and their inherent energy landscape may hence cause an additional energy barrier for the exsolution reaction that results in orientation-dependent differences in the exsolution kinetics.
Molecular electron doping to single-walled carbon nanotubes and molybdenum disulfide monolayers

Published: October 2022

Abstract
Carrier doping is an essential way to inject holes and electrons to electronic materials, which modulates their transport properties. While the substitution of heteroatoms essentially modulates the band structure of most semiconducting materials, chemical (molecular) doping can achieve relatively reliable carrier concentration modulation, particularly for nanocarbons and two-dimensional semiconductors. Compared to p-type counterparts, the stabilization of n-type carbon materials has been a challenge not only for basic science but also for various electronic device applications. This Mini-Review describes rational concepts for, and the results of, a stable n-type doping technique mainly for carbon nanotubes using molecular reactions and interactions. The stable n-type carbon nanotubes with controlled carrier concentration are implemented in complementary circuits and thermoelectric energy harvesters. The molecular and supramolecular n-type doping is not limited for carbon nanotubes, but is utilized in the fabrication of conducting transition metal dichalcogenides such as a molybdenum disulphide (MoS2) monolayer.

Common neural substrates of diverse neurodevelopmental disorders
Authors: Sokolowski H Moriah , Levine Brian 
Published: October 2022

Abstract
Neurodevelopmental disorders are categorized and studied according to their manifestations as distinct syndromes. For instance, congenital prosopagnosia and dyslexia have largely non-overlapping research literatures and clinical pathways for diagnosis and intervention. On the other hand, the high incidence of neurodevelopmental comorbidities or co-existing extreme strengths and weaknesses suggest that transdiagnostic commonalities may be greater than currently appreciated. The core-periphery model holds that brain regions within the stable core perceptual and motor regions are more densely connected to one another compared to regions in the flexible periphery comprising multimodal association regions. This model provides a framework for the interpretation of neural data in normal development and clinical disorders. Considering network-level commonalities reported in studies of neurodevelopmental disorders, variability in multimodal association cortex connectivity may reflect a shared origin of seemingly distinct neurodevelopmental disorders. This framework helps to explain both comorbidities in neurodevelopmental disorders and profiles of strengths and weaknesses attributable to competitive processing between cognitive systems within an individual.
Individualized morphometric similarity predicts body mass index and food approach behavior in school-age children

Published: October 2022

AbstractChildhood obesity is associated with alterations in brain structure. Previous studies generally used a single structural index to characterize the relationship between body mass index(BMI) and brain structure, which could not describe the alterations of structural covariance between brain regions. To cover this research gap, this study utilized two independent datasets with brain structure profiles and BMI of 155 school-aged children. Connectome-based predictive modeling(CPM) was used to explore whether children’s BMI is reliably predictable by the novel individualized morphometric similarity network(MSN). We revealed the MSN can predict the BMI in school-age children with good generalizability to unseen dataset. Moreover, these revealed significant brain structure covariant networks can further predict children’s food approach behavior. The positive predictive networks mainly incorporated connections between the frontoparietal network(FPN) and the visual network(VN), between the FPN and the limbic network(LN), between the default mode network(DMN) and the LN. The negative predictive network primarily incorporated connections between the FPN and DMN. These results suggested that the incomplete integration of the high-order brain networks and the decreased dedifferentiation of the high-order networks to the primary reward networks can be considered as a core structural basis of the imbalance between inhibitory control and reward processing in childhood obesity.

AbstractAdvances in Magnetic Resonance Imaging hardware and methodologies allow for promoting the cortical morphometry with submillimeter spatial resolution. In this paper, we generated 3D self-enhanced high-resolution (HR) MRI imaging, by adapting 1 deep learning architecture, and 3 standard pipelines, FreeSurfer, MaCRUISE, and BrainSuite, have been collectively employed to evaluate the cortical thickness. We systematically investigated the differences in cortical thickness estimation for MRI sequences at multiresolution homologously originated from the native image. It has been revealed that there systematically exhibited the preferences in determining both inner and outer cortical surfaces at higher resolution, yielding most deeper cortical surface placements toward GM/WM or GM/CSF boundaries, which directs a consistent reduction tendency of mean cortical thickness estimation; on the contrary, the lower resolution data will most probably provide a more coarse and rough evaluation in cortical surface reconstruction, resulting in a relatively thicker estimation. Although the differences of cortical thickness estimation at the diverse spatial resolution varied with one another, almost all led to roughly one-sixth to one-fifth significant reduction across the entire brain at the HR, independent to the pipelines we applied, which emphasizes on generally coherent improved accuracy in a data-independent manner and endeavors to cost-efficiency with quantitative opportunities.

Abstract
Our everyday life summons numerous novel sensorimotor experiences, to which our brain needs to adapt in order to function properly. However, tracking plasticity of naturalistic behavior and associated brain modulations is challenging. Here, we tackled this question implementing a prism adaptation-like training in virtual reality (VRPA) in combination with functional neuroimaging. Three groups of healthy participants (N = 45) underwent VRPA (with a shift either to the left/right side, or with no shift), and performed functional magnetic resonance imaging (fMRI) sessions before and after training. To capture modulations in free-flowing, task-free brain activity, the fMRI sessions included resting-state and free-viewing of naturalistic videos. We found significant decreases in spontaneous functional connectivity between attentional and default mode (DMN)/fronto-parietal networks, only for the adaptation groups, more pronouncedly in the hemisphere contralateral to the induced shift. In addition, VRPA was found to bias visual responses to naturalistic videos: Following rightward adaptation, we found upregulation of visual response in an area in the parieto-occipital sulcus (POS) only in the right hemisphere. Notably, the extent of POS upregulation correlated with the size of the VRPA-induced after-effect measured in behavioral tests. This study demonstrates that a brief VRPA exposure can change large-scale cortical connectivity and correspondingly bias visual responses to naturalistic sensory inputs.
Microstimulation in the primary visual cortex: activity patterns and their relation to visual responses and evoked saccades

Published: October 2022

Abstract
Intracortical microstimulation (ICMS) in the primary visual cortex (V1) can generate the visual perception of a small point of light, termed phosphene, and evoke saccades directed to the receptive field of the stimulated neurons. Although ICMS is widely used, a direct measurement of the spatio-temporal patterns of neural activity evoked by ICMS and their relation to the neural responses evoked by visual stimuli or how they relate to ICMS-evoked saccades are still missing. To investigate this, we combined ICMS with voltage-sensitive dye imaging in V1 of behaving monkeys and measured neural activity at a high spatial (meso-scale) and temporal resolution. We then compared the population response evoked by small visual stimuli to those evoked by microstimulation. Both stimulation types evoked population activity that spread over few millimeters in V1 and propagated to extrastriate areas. However, the population responses evoked by ICMS have shown faster dynamics for the activation transients and the horizontal propagation of activity revealed a wave-like propagation. Finally, neural activity in the ICMS condition was higher for trials with evoked saccades as compared with trials without saccades. Our results uncover the spatio-temporal patterns evoked by ICMS and their relation to visual processing and saccade generation.

Abstract
Fractal dimension (FD) is used to quantify brain structural complexity and is more sensitive to morphological variability than other cortical measures. However, the effects of normal aging and sex on FD are not fully understood. In this study, age- and sex-related differences in FD were investigated in a sample of 448 adults age of 19–80 years from a Chinese dataset. The FD was estimated with the surface-based morphometry (SBM) approach, sex differences were analyzed on a vertex level, and correlations between FD and age were examined. Generalized additive models (GAMs) were used to characterize the trajectories of age-related changes in 68 regions based on the Desikan–Killiany atlas. The SBM results showed sex differences in the entire sample and 3 subgroups defined by age. GAM results demonstrated that the FD values of 51 regions were significantly correlated with age. The trajectories of changes can be classified into 4 main patterns. Our results indicate that sex differences in FD are evident across developmental stages. Age-related trajectories in FD are not homogeneous across the cerebral cortex. Our results extend previous findings and provide a foundation for future investigation of the underlying mechanism.
The institutional impossibility of guild socialism
Authors: Hodgson Geoffrey M 
Published: October 2022

Abstract
Guild socialism was developed in the 1906–25 period. It has been held up as a ‘libertarian’ and ‘democratic’ alternative to the statist socialism of the Fabians and the Soviet bloc. This article outlines the basic features of guild socialism, particularly in the most influential version of G. D. H. Cole. Guild socialists wanted to minimise markets and to give higher administrative bodies the right to impose prices in cases of dispute. It is argued here that, despite the intentions of its proponents, guild socialism has a strong centralising dynamic that would undermine its defining aspirations for ‘workers' control’. This centralising dynamic will remain, as long as the guilds are denied legal autonomy, (cooperative) ownership of their means of production and their general right to negotiate prices of their outputs and inputs with buyers and sellers. This diminished capacity for local adjustment, with a potential upward referral of crucial decisions and powers, would add to the informational and task burdens of higher administrative bodies. Much of the previous literature on guild socialism has overlooked these problems. Attention must be paid to legal, as well as other, power relations in the analysis of actual or proposed economic systems.
