A New Species of Limnephilus (Insecta: Trichoptera: Limnephilidae) from China, with Revision of the Genus Limnephilus on the Chinese Mainland

Simple Summary As the most diverse genus in the family Limnephilidae, Limnephilus Leach, 1815 (194 extant species and 9 fossil species), has a wide distribution and a broad range of ecological tolerances among its species. Although it has a high species diversity in the Holarctic region, only 16 species have been recognized in China until now, of which 7 are endemic to China. In this study, a new species of the genus Limnephilus was found. The adult females, larvae, and pupae of this new species were associated with the adult males based on COI sequencing, and all the life stages except for the egg stage are described and illustrated. In addition, the biological and habitat information for this new species is provided. Furthermore, all of the Limnephilus species from the Chinese mainland are revised at the species group level, and diagnoses for species groups and species (keys of groups and species) are given, along with a distribution map. Abstract Fifty individuals of Limnephilus from the Qinghai Province, China, were examined, and their COI barcode sequences were extracted and analyzed. Forty individuals of Limnephilus from the Insect Collection of Nanjing Agricultural University (ICNAU), China, were examined, and photos of the male genitalia of four Limnephilus species are here presented. The males, females, larvae, and pupae of a new species, Limnephilus deqianensis n. sp. , associated via COI barcode sequences, are described and illustrated. Ecological photos of the male, pupal case, and the habitat of the new species L. deqianensis n. sp. are also provided. Five species groups containing all seventeen Chinese Limnephilus species are revised. Diagnoses, keys, and a distribution map of them are provided. All of the sequences have been uploaded to GenBank. All specimens are deposited in the ICNAU, Nanjing, Jiangsu Province, P. R. China.
A Power Electronic Traction Transformer Configuration With Low-Voltage IGBTs for Onboard Traction Application

Solid-State transformer for onboard traction application is also addressed as power electronic traction transformer (PETT), which is used to replace the line frequency traction transformer and four-quadrant converter to further improve efficiency, save installation space, and reduce weight of the onboard equipment. However, based on the conventional PETT configuration with the modular series–parallel structure, it is hard to guarantee the high efficiency and high power density at the same time due to the limitations caused by the switching characteristics of the semiconductor devices, transformer design, and high-voltage insulation design. To deal with the mentioned problem, a PETT configuration and the parameters’ design method for onboard traction application are proposed in this paper to replace the conventional dc/dc stage with the low-voltage insulated gate bipolar translator (IGBTs). By using the proposed configuration, the high-voltage IGBTs can be replaced by the low-voltage IGBTs, which can help reduce switching loss. Meanwhile, zero-current switching or zero-voltage switching for all the IGBTs can be guaranteed, and the number of the medium-frequency transformers (MFTs) will not increase. Therefore, a multiple optimization of PETT, including switching losses, the number of MFTs and switches, and costs, can be finally achieved. Finally, an experimental prototype is built to verify the performance of the proposed PETT configuration.

Hydraulic-drive roll movement control of a spray boom using adaptive robust control strategy

Undesired movements of the spray boom are the main causes of an irregular spray distribution of agro-chemicals; the rolling motion of the boom is particularly significant. This article presents an adaptive robust control scheme for the active pendulum boom suspension to control the roll motion of the spray boom with electro-hydraulic actuators. A hybrid model which combines an analytical modeling procedure with identification techniques of a 28-m spray boom with active suspension is developed. Then, a model-based adaptive robust controller is designed for the precision motion control of the boom, with consideration of the nonlinearities such as uncompensated friction and disturbances and the effect of parameter variations coming from the various hydraulic parameters. A sprayer boom suspension system test rig combined with a 6-degree-of-freedom motion simulator is specifically designed and developed to verify the control scheme; the proposed controller and proportional–integral controller have been implemented on a laboratory experiment. Experimental results reveal that the proposed controller can guarantee a prescribed transient performance and tracking accuracy in the presence of both parametric uncertainties and uncertain nonlinearities; it also means that the model-based adaptive robust control scheme is effective in roll movement control of the spray boom, and then the uniformity of spray distribution can be guaranteed.
Gas source localization and mapping with mobile robots: A review

Within the last couple of decades, there has been increasing research into the use of mobile robots for gas sensing applications. This has led to many different branches of research, most notably on the topics of gas distribution mapping and source localization. This paper aims to provide an up to date and comprehensive overview of the research on these topics for both controlled and uncontrolled environments with ground‐based or aerial robots. To complement other review papers, a greater focus is placed on recent probabilistic algorithms developed for both single robot and multirobot applications.
Tracking ALMA System Temperature with Water Vapor Data at High Frequency

As the world-leading submillimeter telescope, the Atacama Large Millimeter/submillimeter Array observatory is now putting more focus on high-frequency observations at Band 7–10 (frequencies from 275 to 950 GHz). However, high-frequency observations often suffer from rapid variations in atmospheric opacity that directly affect the system temperature T sys. Current observations perform discrete atmospheric calibrations (Atm-cals) every few minutes, with typically 10–20 occurring per hour for high frequency observation and each taking 30–40 s. In order to obtain more accurate flux measurements and reduce the number of atmospheric calibrations (Atm-cals), a new method to monitor T sys continuously is proposed using existing data in the measurement set. In this work, we demonstrate the viability of using water vapor radiometer (WVR) data to track the T sys continuously. We find a tight linear correlation between T sys measured using the traditional method and T sys extrapolated based on WVR data with scatter of 0.5%–3%. Although the exact form of the linear relation varies among different data sets and spectral windows, we can use a small number of discrete T sys measurements to fit the linear relation and use this heuristic relationship to derive T sys every 10 s. Furthermore, we successfully reproduce the observed correlation using atmospheric transmission at microwave modeling and demonstrate the viability of a more general method to directly derive the T sys from the modeling. We apply the semi-continuous T sys from heuristic fitting on a few data sets from Band 7 to Band 10 and compare the flux measured using these methods. We find the discrete and continuous T sys methods give us consistent flux measurements with differences up to 5%. Furthermore, this method has significantly reduced the flux uncertainty due to T sys variability for one data set, which has large precipitable water vapor fluctuation, from 10% to 0.7%.
The Influence of a Special School Placement on Prospective Teachers’ Views About the Nature, Purpose, and Value of Physical Education in England: A Gramscian Critique

ABSTRACT School–based placements have been identified as important for personal and professional development, supporting prospective teachers to critically (re)consider and disrupt normative and ableist practices. Antonio Gramsci’s concept of cultural hegemony was used in this research to explore the influence of a special school placement on prospective teachers’ beliefs about the nature, purpose, and value of physical education (PE) for pupils with special educational needs and disabilities (SEND). Twenty-six prospective teachers from England participated in focus groups prior to and after placement in a special school. Focus group audio recordings were transcribed verbatim and analyzed thematically. Our findings suggest that special school field experiences can contribute toward disrupting hegemonic beliefs about the nature, purpose, and value of PE, and allow prospective teachers to develop more critical, diverse, and nuanced understandings of PE, which may be crucial for providing more inclusive PE experiences for pupils with SEND in both special and mainstream settings. Saying that, we end by offering a note of caution about the transferability and permanence of ideological change, calling for future research that explores the long-term influence of special school placements and transfer to mainstream schools.
Air Pollution and Migration Intention: Evidence from the Unified National Graduate Entrance Examination

Using a unique dataset of applicants for the Unified National Graduate Entrance Examination (UNGEE) of 76 double first-class universities in China, this paper evaluates the causal impact of air pollution on the migration intentions of highly educated talents by exploiting an instrumental variable approach based on annually average wind speed. We find that a 1 ug/m3 increase in the annually average PM2.5 concentration in destination cities decreases the number of applicants for the UNGEE of elite universities by about 250, but better university quality and more abundant educational resources can weaken the effect partially. A heterogeneity analysis indicates that the university-city choices of applicants are shifting from north to south. Our findings suggest that air pollution may lead to the loss of high human capital.
The transcriptional repressor SmvR is important for chlorhexidine decreased susceptibility in Enterobacter cloacae complex

Major Facilitator Superfamily (MFS) efflux pumps have been shown to be important for 29 bacterial cells to cope with biocides such as chlorhexidine (CHX), a widely used molecule in 30 hospital settings. In this work, we evaluated the role of two genes: smvA and smvR in CHX 31 resistance in Enterobacter cloacae complex (ECC) . smvA encodes an MFS pump whereas 32 smvR , located upstream of smvA, codes for a TetR-type transcriptional repressor. To this aim, 33 we constructed corresponding deletion mutants from the ATCC 13047 strain (MIC = 2 mg/L) 34 as well as strains overexpressing smvA or smvR both in ATCC 13047 and three clinical 35 isolates exhibiting elevated MICs of CHX (16-32 mg/L). Determination of MICs revealed that 36 smvA played a modest role in CHX resistance, contrarily to smvR that modulated the ability of 37 ECC to survive in the presence of CHX. In clinical isolates, the overexpression of smvR 38 significantly reduced MICs of CHX (2-8 mg/L). Sequences analyses of smvR and promotor 39 regions pointed out substitutions in conserved regions. Moreover, transcriptional studies 40 revealed that SmvR acted as a repressor of smvA expression even if no quantitative correlation 41 between the level of smvA mRNA and MICs of CHX could be observed. On the other hand, 42 overproduction of smvA was able to complement the lack of the major resistance-nodulation- 43 cell division (RND) superfamily efflux pump AcrB and restored resistance to ethidium 44 bromide and acriflavine. Although SmvA could efflux biocides such as CHX, other actors, of 45 which the expression is under SmvR control, should play critical role in ECC.

In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. The purpose of the consortium is to coordinate and facilitate the efforts of a diverse group of researchers in the broad areas of the interstellar medium, Galactic magnetic fields and cosmic rays, and our overarching goal is to develop more comprehensive insights into the structures and roles of interstellar magnetic fields and their interactions with cosmic rays within the context of Galactic astrophysics. The ongoing rapid development of observational and numerical facilities and techniques has resulted in a widely felt need to advance this subject to a qualitatively higher level of self-consistency, depth and rigour. This can only be achieved by the coordinated efforts of experts in diverse areas of astrophysics involved in observational, theoretical and numerical work. We present our view of the present status of this research area, identify its key unsolved problems and suggest a strategy that will underpin our work. The backbone of the consortium is the Interstellar MAGnetic field INference Engine, a publicly available Bayesian platform that employs robust statistical methods to explore the multi-dimensional likelihood space using any number of modular inputs. This tool will be used by the IMAGINE Consortium to develop an interpretation and modelling framework that provides the method, power and flexibility to interfuse information from a variety of observational, theoretical and numerical lines of evidence into a self-consistent and comprehensive picture of the thermal and nonthermal interstellar media. An important innovation is that a consistent understanding of the phenomena that are directly or indirectly influenced by the Galactic magnetic field, such as the deflection of ultra-high energy cosmic rays or extragalactic backgrounds, is made an integral part of the modelling. The IMAGINE Consortium, which is informal by nature and open to new participants, hereby presents a methodological framework for the modelling and understanding of Galactic magnetic fields that is available to all communities whose research relies on a state of the art solution to this problem.
Range‐based localisation of a wireless sensor network using Jaya algorithm

Node localisation plays a significant role in wireless sensor networks, as most of the applications require exact location of sensor nodes. To obtain the exact location of sensor nodes, a range-based localisation method based on Jaya optimisation using received signal strength indicator (RSSI) is proposed. The distance between the target node and the reference nodes is obtained from the measured RSSIs using regression-based log normal shadowing model. Further, improvement in the localisation accuracy is accomplished by formulating the location of target node as an optimisation problem. Jaya optimisation algorithm is adopted, as it is parameter-free and efficient. The Jaya algorithm is used for estimating the distance as well as the coordinates of the target node. The proposal is compared with particle swarm optimisation and validated through simulation and hardware experiments. The maximum localisation error using Jaya and particle swarm optimisation through simulation is observed to be 0.08 and 0.37 m, respectively. Real-time experiments using Jaya algorithm exhibited the maximum localisation error of about 0.14 m for indoor environment and 0.3 m for outdoor environment. The results of the proposed methodology show significant improvement in terms of accuracy.
Growth anisotropy of the extracellular matrix drives mechanics in a developing organ

The final size and shape of organs results from volume expansion by growth and shape changes by contractility. Complex morphologies arise from differences in growth rate between tissues. We address here how differential growth drives epithelial thickening and doming during the morphogenesis of the growing Drosophila wing imaginal disc. We report that 3D morphology results from elastic deformation due to differential growth between the epithelial cell layer and its enveloping extracellular matrix (ECM). Furthermore, the ECM envelope exhibits differential growth anisotropy (i.e. anisotropic expansion in 3D), growing in-plane on one side, but out of plane on the other side. The elasticity, anisotropy and morphogenesis is fully captured by a mechanical bilayer model. Moreover, differential expression of the Matrix metalloproteinase MMP2 controls growth anisotropy of the two ECM layers. This study shows that the ECM is a controllable mechanical constraint whose intrinsic growth anisotropy directs tissue morphogenesis in a developing organ.
Human galectin-9 promotes the expansion of HIV reservoirs in vivo in humanized mice

Objective: The human endogenous protein galectin-9 (Gal-9) reactivates latently HIV-infected cells in vitro and ex vivo, which may allow for immune-mediated clearance of these cells. However, Gal-9 also activates several immune cells, which could negatively affect HIV persistence by promoting chronic activation/exhaustion. This potential ‘double-edged sword’ effect of Gal-9 raises the question of the overall impact of Gal-9 on HIV persistence in vivo. Design: We used the BLT (bone marrow, liver, thymus) humanized mouse model to evaluate the impact of Gal-9 on HIV persistence in vivo during antiretroviral therapy (ART). Methods: Two independent cohorts of ART-suppressed HIV-infected BLT mice were treated with either recombinant Gal-9 or phosphate-buffered saline control. Plasma viral loads and levels of tissue-associated HIV DNA and RNA were measured by qPCR. Immunohistochemistry and HIV RNAscope were used to quantify CD4+ T, myeloid, and HIV RNA+ cells in tissues. T cell activation and exhaustion were measured by flow cytometry, and plasma markers of inflammation were measured by multiplex cytokine arrays. Results: Gal-9 did not induce plasma markers of inflammation or T cell markers of activation/exhaustion in vivo. However, the treatment significantly increased levels of tissue-associated HIV DNA and RNA compared to controls (P = 0.0007 and P = 0.011, respectively, for cohort I and P = 0.002 and P = 0.005, respectively, for cohort II). RNAscope validated the Gal-9 mediated induction of HIV RNA in tissue-associated myeloid cells, but not T cells. Conclusions: Our study highlights the overall adverse effects of Gal-9 on HIV persistence and the potential need to block Gal-9 interactions during ART-suppressed HIV infection.
The auditory perception in the patients in state of coma: a bibliographical revision

Much is still needed to be discovered by the neuroscience in relation to the consciousness regarding cognitive processes and the auditive perception in coma. Thus, this study is a bibliographic review on the auditive perception of patients in coma and shows its relevance to explain and identify evidence. To identify, in the publications found, the gaps, consistencies and inconsistencies on this subject. This study consists of a bibliographical survey based on LILACS and PUBMED database. Ten articles were selected about the subject, none of them are national publications. Most of the selected studies were published within the period of 1971-1995 (80%), by the United States (70%), as longitudinal research (50%) or study of case (30%); the sample in general varied between 1 and 5 (70%), the majority used music (80%); the EEG (60%) and behavior observation (50%) were the most used measuring ways of the responses to the stimulus. The procedures were varied, however most of the studies, show that there is an auditory perception in patients with coma.
Multiset correlation and factor analysis enables exploration of multi-omic data

Here, we introduce Multi-set Correlation and Factor Analysis, an unsupervised integration method that enables fast inference of shared and private factors in multi-modal data. Applied to 614 ancestry-diverse participant samples across five ‘omics types, MCFA infers a shared space that captures clinically relevant molecular processes.
Activity-Dependent Stabilization of Nascent Dendritic Spines Requires Nonenzymatic CaMKIIα Function

The outgrowth and stabilization of nascent dendritic spines are crucial processes underlying learning and memory. Most new spines retract shortly after growth; only a small subset is stabilized and integrated into the new circuit connections that support learning. New spine stabilization has been shown to rely upon activity-dependent molecular mechanisms that also contribute to long-term potentiation (LTP) of synaptic strength. Indeed, disruption of the activity-dependent targeting of the kinase CaMKIIα to the GluN2B subunit of the NMDA-type glutamate receptor disrupts both LTP and activity-dependent stabilization of new spines. Yet it is not known which of CaMKIIα's many enzymatic and structural functions are important for new spine stabilization. Here, we used two-photon imaging and photolysis of caged glutamate to monitor the activity-dependent stabilization of new dendritic spines on hippocampal CA1 neurons from mice of both sexes in conditions where CaMKIIα functional and structural interactions were altered. Surprisingly, we found that inhibiting CaMKIIα kinase activity either genetically or pharmacologically did not impair activity-dependent new spine stabilization. In contrast, shRNA knockdown of CaMKIIα abolished activity-dependent new spine stabilization, which was rescued by co-expressing shRNA-resistant full-length CaMKIIα, but not by a truncated monomeric CaMKIIα. Notably, overexpression of phospho-mimetic CaMKIIα-T286D, which exhibits activity-independent targeting to GluN2B, enhanced basal new spine survivorship in the absence of additional glutamatergic stimulation, even when kinase activity was disrupted. Together, our results support a model in which nascent dendritic spine stabilization requires structural and scaffolding interactions mediated by dodecameric CaMKIIα that are independent of its enzymatic activities.
