Published: November 2022

Abstract
In order to achieve accurate evaluation of the stability of the surrounding rocks in complex underground mining clusters, 3DMine-Midas-FLAC3D was used to form an accurate numerical modelling analysis technique for complex mining clusters, and the technique was applied to the analysis of the stability of the surrounding rocks in complex mining clusters in a lead-zinc mine to achieve an accurate evaluation of the stability of the surrounding rocks in complex mining clusters in this mine, and to reveal the ground pressure manifestation pattern of complex mining clusters. The results of the study show that the accurate numerical modelling analysis method has better consistency with the empirical method (Laubscher method and Mathews stability diagram method) than the empirical method, and at the same time, it provides a more reliable and accurate evaluation method for the stability analysis of large complex mining area clusters from multiple perspectives and indicators, effectively compensating for the limitations of the empirical method for the stability evaluation of complex form mining sites.

Authors: Sun Xu , Lu Xiangxing , Li Kaitian 
Published: November 2022

Abstract
A denudation-dissolution hilly area about 20km southeast of Jinan city, Shandong Province, China is characterized by karst features. The upper part of the area is covered by quaternary Holocene flood and slope deposits, and the lower bedrock is Ordovician limestone, which is a moderately weathered massive structure with developed joints and fissured fractures, and solution grooves can be seen locally. The local government to better serve the surrounding residents and the surrounding facilities, here is planned for the substation, for later security construction, electrical resistivity tomography (ERT) method and ground penetrating radar (GPR) method were used to investigate the underground karst caves. The aim of the joint use of the two methods is to better describe the characteristics of karst landform, a 160 MHz shielding antenna was employed in the GPR survey, while the frequency limits the scope of the depth of the electromagnetic waves can reach. However, it provides a lot of shallow stratigraphic information, which well represents the boundary between overburden and bedrock and the development of karst. The use of ERT method further makes up for the depth defects of the GPR method, and two-dimensional imaging of underground resistivity distribution was carried out, which also helps to further identify the characteristics of underground karst. The combination of the two geophysical methods can accurately delineate the development of underground karst, which also proves that the combination of the GPR method and ERT method has good application value in karst landform detection, and can also be applied to a similar geological survey.

Abstract
International standardization has become more important because of the trend of economic globalization. Whoever has mastered the standards will have the right to speak. In developed countries, standard competition is the apex of all fields, and promoting the internationalization of domestic technology and standards is an effective way to promote the country’s market leader and international status. With the continuous improvement of China’s market competitiveness, the internationalization of standards related to the power industry has become more essential, therefore, it is urgent to further strengthen the development process of internationalization of standards in China’s power industry. Starting from the international standard project in the field of smart grid, this paper studies the difficulties of current international standard project in the field of smart grid, in addition, systematically analyzes the key problems of the standard project in the field of power grid under the internationalization of China’s standards. At last, the practical measures are given.

Abstract
Gravity inversion is a typical geophysical inversion method that obtains the underground density distribution by analyzing the gravity anomaly. Normally, it can be divided into geophysics-based and deep learning based inversion. The 3D geophysics-based inversion is a time- and memory-consuming method, so 3D inversion is not routinely implemented in practical data interpretation. Here, we propose a deep learning method to transfer the 3D inversion problem to a multiple layers 2D mapping problem by decomposing the 3D target into four 2D images, including the horizontal location, vertical center, thickness and density distribution. This method is denoted as “decomposition network”. By implementing synthetic experiments with regular and complex models, and comparing with the 3D U-Net inversion, the proposed network has proved can reconstruct underground targets with high accuracy and high efficiency.
Amplification phenomenon and mechanism analysis of ground fissure activity rate in Jiaocheng fault
Authors: Han Xiaofei , Hao Xuejing , Dong Bin , Shi Shuangshuang , Xue Xiaodong 
Published: November 2022

Abstract
Jiaocheng fault ground fissure is the longest ground fissure extending intermittently in Fen Wei fault depression zone. The occurrence and development of ground fissures are affected by rainfall, groundwater pumping, fault activity, strata and other factors. The research shows that with the rainwater flowing down and replenishing the confined water layer, there will be undercutting, scouring and hollowing, which will aggravate the development of ground fissures; In the structural area, due to the multi-stage activity of the fault, a strong tensile stress area is formed, resulting in the rapid reactivation, expansion and rebirth of the ground fracture. At the same time, there is a thicker and finer silty clay layer that is easier to lose with water, which is another incentive factor for the rapid development of the ground fracture. However, when the tectonic action causes the dislocation of the aquifer and water resisting layer and blocks the loss of formation materials, the ground fracture will lose its development conditions. Jiaocheng fault is the main controlling factor for the shaping, formation, development and continuous influence of the geological environment of Jiaocheng ground fracture, while precipitation, groundwater exploitation and natural discharge are the incentive factors, and the loss of stratum material is the necessary condition. The North basin of Tianzhuang fault cannot form ground fracture without necessary conditions.

Published: November 2022

Abstract
Refugees are one of the most at-risk groups to experience economic exclusion and poverty due to the often abrupt and unplanned nature of their forced displacement and structural barriers after resettlement. This study aimed to explore the prevalence of multidimensional poverty (deprivations in five domains of education, health, living standard, economic security and housing) and factors associated with this complex problem amongst newly resettled refugees in the USA. Using 2016, 2017 and 2018 Annual Survey of Refugees data-sets and an adjusted version of the census Multidimensional Deprivation Index, poverty in different aspects of life was measured. Multivariate correlational analyses were utilised to explore possible associations between poverty, length of residence in the USA, permanent residency status and English language proficiency. The findings of this study suggested that over half of the surveyed refugees were multidimensionally poor. Limited English language proficiency at the time of the data collection was the best predictor of multidimensional poverty amongst the explored factors. Estimated rates of poverty amongst refugees call for further attention to policies fostering the economic integration of refugees as new Americans in the USA. Recommendations for resources, interventions and policies fostering refugees’ economic integration and well-being were discussed.
New molecular evidence for Canarian endemicRuta(Rutaceae: Ruteae) reveals a complex evolutionary history and overlooked diversification processes

Published: November 2022

AbstractWe studied four currently recognized endemics of Ruta (Rutaceae) from the Canary Islands, an oceanic biodiversity hotspot, to identify genetic variation, reconstruct evolutionary relationships and clarify the taxonomic delimitation of several recently discovered populations. We analysed four plastid DNA regions for a thorough population sampling of Ruta oreojasme on Gran Canaria, R. pinnata on Tenerife and La Palma and R. microcarpa and the only known population of the recently described R. nanocarpa on La Gomera. Bayesian clock dating analysis, haplotype network and ancestral area reconstructions were carried out. Our results reveal a complex, extremely dynamic and largely overlooked pattern of colonization and evolutionary history of Ruta in the archipelago. Thirty haplotypes were found, but only one of them was shared across more than one island. Species divergence and all colonization events in the Canary Islands were dated from the late Pliocene to the Pleistocene, and R. oreojasme has an earlier origin than its Canarian congeners. Multiple secondary colonization events between and within islands account for the diversification of R. pinnata and R. microcarpa. Our data cannot discard a possible independent origin of R. oreojasme and do not support the currently accepted circumscription of R. pinnata and R. microcarpa. Rather, the high levels of genetic differentiation detected suggest the existence of ongoing diversification processes and of new taxa. Urgent population-level conservation efforts should be undertaken, especially focused on the single population on La Gomera that can be attributed to R. microcarpa, R. nanocarpa and genetically distinct populations from La Palma and the palaeo-islands of Tenerife.
Temporopolar regions of the human brain
Authors: Mesulam M Marsel 
Published: November 2022

AbstractFollowing prolonged neglect during the formative decades of behavioural neurology, the temporopolar region has become a site of vibrant research on the neurobiology of cognition and conduct. This turnaround can be attributed to increasing recognition of neurodegenerative diseases that target temporopolar regions for peak destruction. The resultant syndromes include behavioural dementia, associative agnosia, semantic forms of primary progressive aphasia and semantic dementia. Clinicopathological correlations show that object naming and word comprehension are critically dependent on the language-dominant (usually left) temporopolar region, whereas behavioural control and non-verbal object recognition display a more bilateral representation with a rightward bias. Neuroanatomical experiments in macaques and neuroimaging in humans show that the temporoparietal region sits at the confluence of auditory, visual and limbic streams of processing at the downstream (deep) pole of the ‘what’ pathway. The functional neuroanatomy of this region revolves around three axes, an anterograde horizontal axis from unimodal to heteromodal and paralimbic cortex; a radial axis where visual (ventral), auditory (dorsal) and paralimbic (medial) territories encircle temporopolar cortex and display hemispheric asymmetry; and a vertical depth-of-processing axis for the associative elaboration of words, objects and interoceptive states. One function of this neural matrix is to support the transformation of object and word representations from unimodal percepts to multimodal concepts. The underlying process is likely to start at canonical gateways that successively lead to generic (superordinate), specific (basic) and unique levels of recognition. A first sign of left temporopolar dysfunction takes the form of taxonomic blurring where boundaries among categories are preserved but not boundaries among exemplars of a category. Semantic paraphasias and coordinate errors in word–picture verification tests are consequences of this phenomenon. Eventually, boundaries among categories are also blurred and comprehension impairments become more profound. The medial temporopolar region belongs to the amygdalocentric component of the limbic system and stands to integrate exteroceptive information with interoceptive states underlying social interactions. Review of the pertinent literature shows that word comprehension and conduct impairments caused by temporopolar strokes and temporal lobectomy are far less severe than those seen in temporopolar atrophies. One explanation for this unexpected discrepancy invokes the miswiring of residual temporopolar neurons during the many years of indolently progressive neurodegeneration. According to this hypothesis, the temporopolar regions become not only dysfunctional but also sources of aberrant outputs that interfere with the function of areas elsewhere in the language and paralimbic networks, a juxtaposition not seen in lobectomy or stroke.
An ecological investigation of the capacity to follow simultaneous speech and preferential detection of ones’ own name
Authors: Pinto Danna , Kaufman Maya , Brown Adi , Zion Golumbic Elana 
Published: November 2022

Abstract
Many situations require focusing attention on one speaker, while monitoring the environment for potentially important information. Some have proposed that dividing attention among 2 speakers involves behavioral trade-offs, due to limited cognitive resources. However the severity of these trade-offs, particularly under ecologically-valid circumstances, is not well understood. We investigated the capacity to process simultaneous speech using a dual-task paradigm simulating task-demands and stimuli encountered in real-life. Participants listened to conversational narratives (Narrative Stream) and monitored a stream of announcements (Barista Stream), to detect when their order was called. We measured participants’ performance, neural activity, and skin conductance as they engaged in this dual-task. Participants achieved extremely high dual-task accuracy, with no apparent behavioral trade-offs. Moreover, robust neural and physiological responses were observed for target-stimuli in the Barista Stream, alongside significant neural speech-tracking of the Narrative Stream. These results suggest that humans have substantial capacity to process simultaneous speech and do not suffer from insufficient processing resources, at least for this highly ecological task-combination and level of perceptual load. Results also confirmed the ecological validity of the advantage for detecting ones’ own name at the behavioral, neural, and physiological level, highlighting the contribution of personal relevance when processing simultaneous speech.

AbstractBackgroundPatients with suspected extrapulmonary tuberculosis are often treated empirically. We hypothesized that extended focused assessment with sonography for human immunodeficiency virus (HIV) and tuberculosis (eFASH), in combination with other tests, would increase the proportion of correctly managed patients with suspected extrapulmonary tuberculosis.MethodsThis trial in adults with suspected extrapulmonary tuberculosis was performed in a rural and an urban hospital in Tanzania. Participants were randomized 1:1 to intervention or routine care, stratified by site and HIV status. All participants underwent clinical evaluation, chest radiography, and testing with sputum Xpert MTB/RIF and urine Xpert MTB/RIF Ultra assays. The intervention was a management algorithm based on results of eFASH plus microbiology, adenosine deaminase (ADA), and chest radiography. The primary outcome was the proportion of correctly managed patients. The presence of positive microbiological or ADA results defined definite tuberculosis. An independent end-point review committee determined diagnoses of probable or no tuberculosis. We evaluated outcomes using logistic regression models, adjusted for randomization stratification factors.ResultsFrom September 2018 to October 2020, a total of 1036 patients were screened and 701 were randomized (350 to the intervention and 351 to the control group). Of participants in the intervention group, 251 (72%) had a positive eFASH outcome. In 258 (74%) of the intervention and 227 (65%) of the control participants antituberculosis was initiated treatment at baseline. More intervention participants had definite tuberculosis (n = 124 [35%]), compared with controls (n = 85 [24%]). There was no difference between groups for the primary outcome (intervention group, 266 of 286 [93%]; control group, 245 of 266 [92%]; odds ratio, 1.14 [95% confidence interval: .60–2.16]; P = .68). There were no procedure-associated adverse events.ConclusionseFASH did not change the proportion of correctly managed patients but increased the proportion of those with definite tuberculosis.Clinical Trials RegistrationPan African Registry: PACTR201712002829221.
Telemental Health for Rural University-Assisted Community Schools
Authors: Lee Youjung , Bronstein Laura , Cook Kelley 
Published: November 2022

Abstract
Since the COVID-19 outbreak, children and families in rural communities have been experiencing unprecedented long-term social isolation and insufficient access to mental health services. Prior to the pandemic, access to mental healthcare in rural communities was already inadequate, leading rural populations to be routinely underserved when facing significant social issues and mental health needs. Even though the pandemic has disrupted the traditional delivery of mental healthcare and exacerbated needs, isolated children and families in rural areas can benefit from mental health services through a telemental health approach. This article presents an innovative telemental health practice model that implements solution-focused brief therapy with social work interns in rural university-assisted community schools (UACS). Implications for policies supporting telemental health in rural UACS, social work education, and evaluation are presented.
The Chevalier de Quincy: an officer and his musical passe-partout
Authors: Sadie Goode Julie Anne 
Published: November 2022

Abstract
In common with many military officers at the turn of the 18th century, Joseph Sevin kept a journal that chronicled army life on and off the battlefield. His memoirs, covering the years 1697 to 1713, are of particular interest because they reveal his pleasure in making music with his fellow officers and the women whom he met socially. While boasting of only modest attainments, the Chevalier de Quincy adored his basse de viole and took it everywhere he went in the course of the War of the Spanish Succession, from Paris to the châteaux of Quincy, Versailles and Fontainebleau, to Provence, Flanders and Italy. His descriptions bring to life the musical occasions in which he took part or simply attended. They also mention fellow officers who we know played and enjoyed the viol. Among the many bonds between members of the noblesse militaire, music can at last be counted.

Abstract
Lactobacillaceae are an important family of lactic acid bacteria that play key roles in the gut microbiome of many animal species. In the honey bee (Apis mellifera) gut microbiome, many species of Lactobacillaceae are found, and there is functionally important strain-level variation in the bacteria. In this study, we completed whole-genome sequencing of 3 unique Lactobacillaceae isolates collected from hives in Virginia, USA. Using 107 genomes of known bee-associated Lactobacillaceae and Limosilactobacillus reuteri as an outgroup, the phylogenetics of the 3 isolates was assessed, and these isolates were identified as novel strains of Apilactobacillus kunkeei, Lactobacillus kullabergensis, and Bombilactobacillus mellis. Genome rearrangements, conserved orthologous genes (COG) categories and potential prophage regions were identified across the 3 novel strains. The new A. kunkeei strain was enriched in genes related to replication, recombination and repair, the L. kullabergensis strain was enriched for carbohydrate transport, and the B. mellis strain was enriched in transcription or transcriptional regulation and in some genes with unknown functions. Prophage regions were identified in the A. kunkeei and L. kullabergensis isolates. These new bee-associated strains add to our growing knowledge of the honey bee gut microbiome, and to Lactobacillaceae genomics more broadly.
