Analysis of a mosquito life cycle model

International audience The gonotrophic cycle of mosquitoes conditions the frequency of mosquito-human contacts. The knowledge of this important phenomenon in the mosquito life cycle is a fundamental element in the epidemiological analysis of a communicable disease such as mosquito-borne diseases.In this work, we analyze a deterministic model of the complete life cycle of mosquitoes which takes into account the principal phases of female mosquitoes' gonotrophic cycle, and the Sterile Insect technique combined with the use of insecticide as control measures to fight the proliferation of mosquitoes. We compute the corresponding mosquito reproductive number N ∗ and prove the global asymptotic stability of trivial equilibrium. We prove that the model admits two non-trivial equilibria whenever N^{∗} is greater than another threshold, N_c, which the total number of sterile mosquitoes depends on. Numerical simulations, using mosquito parameters of the Aedes species, are carried out to illustrate our analytical results and permit to show that the strategy which consists in combining the sterile insect technique with adulticides, when it is well done, effectively combats the proliferation of mosquitoes.
Comparative leaf and root anatomy of two Dendrobium species (Orchidaceae) from different habitat in relation to their potential adaptation to drought

Dendrobium capra and Dendrobium arcuatum are closely related in phylogeny, but they have very contrasting vegetative morphology and habitats. D. capra is known as a species that is well-adapted to dry lowland teak forest habitat in East Java, where most trees drop their leaves in summer, while D. arcuatum has adapted to mid or high land moist forest at elevation up to 800 m dpl. In order to investigate their potential adaptation to drought stress in the climate change era, we have compared and analyzed the leaf and root anatomical characteristics of both species. Transversal sections were made using hand mini microtome, dehydrated in graded alcohol series and stained with safranin 1 % and fastgreen 1 %. Leaf scraping technique has been used to prepare paradermal sections, and then dehydrated in graded alcohol series and stained with safranin 1 %. Quantitative anatomical characteristics between D. capra and D. arcuatum have been compared using a t-test. The result showed that there were significant differences on anatomical characters between both species. Compared to D. arcuatum, D. capra shows more developed anatomical features for adapting to drought and dry condition. These anatomical features were a thicker cuticle, thicker epidermis, presence of hypodermis, thicker mesophyll, broader primary vascular bundle, well developed xylem’s sclerenchyma, lower stomatal density, thicker and high proportion of velamen.Dendrobium capra and Dendrobium arcuatum are closely related in phylogeny, but they have very contrasting vegetative morphology and habitats.

Generative adversarial framework‐based one‐day‐ahead forecasting method of photovoltaic power output

: Accurately forecasting the energy yields of photovoltaic (PV) systems is of great benefit to the power optimization of smart grid. However, most existing data-driven paradigm-based forecasting methods often suffer from the diversity of power fluctuation patterns, which results in poor performance while dealing with distributed PV systems that are more sensitive to external factors. To overcome this problem, this study first formulates an input data scheme based on historical PV power data, in which a novel decomposition algorithm is proposed to separate the structural information and fluctuation components in the power data. Then, a forecasting model based on the generative adversarial framework is developed, whose generative module can obtain the ability to learn the desired feature distribution with the discriminator, rather than selecting features via a certain trained preference. Moreover, the proposed method takes into account some meteorological elements to further characterise the power fluctuations. Extensive self-evaluation and comparison with several state-of-the-art methods highlight the superiority of the proposed method.
TMS orientation and pulse waveform manipulation activates different neural populations: direct evidence from TMS-EEG

Monophasic and biphasic TMS pulses and coil orientations produce different responses in terms of motor output and sensory perception. Those differences have been attributed to the activation of specific neural populations. However, up to date, direct evidence supporting this hypothesis is still missing since studies were mostly based on indirect measures of cortical activation, i.e., motor evoked potentials or phosphenes. Here, we investigated for the first time the impact of different coil orientations and waveforms on a non-primary cortical area, namely the premotor cortex, by measuring TMS evoked EEG potentials (TEPs). We aimed at determining whether TEPs produced by differently oriented biphasic and monophasic TMS pulses diverge and whether these differences are underpinned by the activation of specific neural populations. To do so, we applied TMS over the right premotor cortex with monophasic or biphasic waveforms oriented perpendicularly (in the anterior-posterior direction and vice-versa) or parallel (latero-medial or medio-laterally) to the target gyrus. EEG was concurrently recorded from 60 electrodes. We analyzed TEPs at the level of EEG sensors and cortical sources both in time and time-frequency domain. Biphasic pulses evoked larger early TEP components, which reflect cortical excitability properties of the underlying cortex, in both parallel directions when compared to the perpendicular conditions. Conversely, monophasic pulses, when oriented perpendicularly to the stimulated gyrus, elicited a greater N100, which is a reliable TEP component linked to GABAb-mediated inhibitory processes, than when parallel to the gyrus. Our results provide direct evidence supporting the hypothesis that TMS pulse waveform and TMS coil orientations affect which neural population is engaged.
Psychological need-supportive instruction improves novel skill performance, intrinsic motivation, and enjoyment: a cluster-randomised study

ABSTRACT This study aimed, first, to test the efficacy of the self-determination theory -centred need-supportive instruction on motivation, novel skill performance, enjoyment, and state anxiety, and second, to test whether the intervention impact followed the theoretical stipulation of the theory. A sample of 59 college undergraduate students (M = 20.26 ± 1.90; 75% female) was allocated to either a need-supportive or –depriving condition. Motivational regulations, skill performance in juggling, enjoyment, and state anxiety were measured before and after the 5 × 45 min trial. The covariates assessed were the time of the condition, gender, trait anxiety, causality orientations, and task interest. The intervention had a statistically significant between-group effect on intrinsic motivation (F(1, 49) = 5.52, p < . 023, η 2 = . 10), skill performance (F(1, 48) = 9.23, p = . 004, η 2 = 0.16), and enjoyment (F(1, 49) = 4.89, p = . 032, η 2 = . 09), but no differences in other motivational regulations or state anxiety were detected. In addition, the path analysis showed a positive motivational pathway, with the intervention impacting intrinsic motivation (β = .55), integrated regulation (β = .30) and amotivation (β = −.27), which impacted positively skill performance (R 2 = .42) and enjoyment (R 2 = .58). It can be concluded that need-supportive instruction is beneficial in improving participants’ intrinsic motivation, skill performance, and enjoyment when compared to need-depriving instruction. Autonomous motivation and an absence of amotivation toward the task seem to instrumental mediators between the need-supportive intervention and novel skill performance and enjoyment.
Percutaneous Reduction and Hollow Screw Fixation Versus Open Reduction and Internal Fixation for Treating Displaced Intra-Articular Calcaneal Fractures

Background We investigated the outcomes of displaced intra-articular calcaneal fractures (DIACFs) treated by percutaneous reduction and hollow screw fixation (PRHCF) versus open reduction and internal fixation (ORIF). Material/Methods Seventy-one patients were randomly allocated to group A (by PRHCF) and group B (by ORIF). Operative time, visual analogue scale (VAS) score, time from injury to operation, postoperative hospital stay, preoperative and postoperative radiographic measurements, and complications were recorded. Functional outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scores. Results Finally, 59 patients were followed up for at least 12 months (range, 12–24 months). Group A showed significantly more advantages than group B in term of operative time, intraoperative blood loss, time to operation, postoperative hospital stay, and postoperative pain relief during the first 3 days (P<0.001). However, more intraoperative fluoroscopy was required in group A than in group B (P<0.001). The calcaneal width, height, length, Böhler angle, and Gissane angle in each group were significantly improved postoperatively (all P<0.001), although not significantly different in the postoperative comparisons between both groups. The AOFAS scores were slightly superior in group A than in group B (88.3 vs. 86.4, P=0.08). The rate of incidence of postoperative complications was lower in group A than in group B (3.2% vs. 10.8%, respectively; OR, 0.28, 95% CI, 0.03 to 2.84), although there was no significant difference (P=0.337). Conclusions PRHCF showed comparable clinical and radiological outcomes as ORIF, demonstrating it is a safe and effective alternative in treating DIACFs.
An Investigation of Three-Way Catalytic Converter for Various Inlet Cone Angles Using CFD

Three-way catalytic converters are utilized to minimize exhaust emissions. The efficient working of catalytic converter depends upon the flow field developed inside the converter. Due to the prevailing stringent norms, such as Bharat stage-VI, it is essential to create and design a high performing converter having uniform flow distribution within the converter to meet these norms. An easy way to gain an almost sufficiently homogeneous stream circulation is to compose the diffuser inclination minimally and correspondingly to manufacture the cone angle length long enough. The objective of the study is to examine an automobile catalytic convertor to present a detail and comprehensive report on the key parameters affecting the flow uniformity inside the converter and thus attempting to achieve minimum pressure drop across the converter to reduce the backpressure. They are modifying the existing geometry of the catalytic converter to have more uniform flow within the convertor. The analysis had been carried out with varying diffuser angles- 57.3, 52.3, and 45 degrees separately. Simulation program using computational fluid dynamics (CFD) software package STAR CCM + 11.02 was used. The monolith design with a 52.3o cone angle evaluated with computations provides an actual parabolic curve, which gives a laminar flow within the catalytic converter, which in turn will increase the conversion efficiency of the converter by 1.060 %. The pressure drop within the monolith is also reduced by 3.7 Pa. This accounts to be a reduction in backpressure up to 5%, thus reduces brake specific fuel consumption of automobiles. The results are validated with the literature. The result shows the overall pressure drop augments with velocity. The temperature effect on light-off performance also studied.
Anterior or posterior approach in the surgical treatment of cervical radiculopathy; neurosurgeons’ preference in the Netherlands

Background For cervical foraminal nerve root decompression, anterior cervical discectomy with fusion (ACDF) or posterior cervical foraminotomy (PCF) can be applied. Amongst neurosurgeons, there seems to be a tendency to prefer ACDF over PCF, even though there are some advantages in favor of PCF. The object of present study is to evaluate which factors determine the choice for an anterior or posterior surgical approach in patients with a cervical radicular syndrome based on foraminal pathology. Methods A web-based survey was sent to all 133 neurosurgeons in the Netherlands. The first part focused on general perceived (dis)advantages of ACDF and PCF. The second part concerned questions about the choice between the two procedures. Furthermore, it was analyzed if exposure during training, amount of performed surgeries, assumed reoperation and complication rates influenced the choice of procedure by conducting Chi-square tests with post-hoc analysis. Results A total of 56 neurosurgeons responded (42%). Of these, 77% performed more than 10 ACDF and 25% more than 10 PCF annually. An overall preference for ACDF was observed, even when differentiating for a pure disc prolapse, a spondylotic or a combined stenosis. The most relative important factors for motivating the preference for either ACDF or PCF were: the assumed best decompression of the nerve root (18%), perceived congruence with current literature (16%), exposure during residency (12%), personal comfort with the procedure (11%), and experience with the technique (11%). Conclusions In this survey, there was an overall preference for ACDF above PCF for the surgical treatment of a foraminal cervical radiculopathy. In addition to subjective factors as “experience” and “ comfort” with the procedure, the respondents often motivated their choice as “the best one according to literature”. As there is currently no evidence about the superiority of any of the procedures in literature, this assumption is remarkable.
Predict passive seismic events with a convolutional neural network

The ample size of time lapse data requires tremendous event detection and source locating capabilities, especially in areas like shale gas exploration regions where a large number of passive seismic events are often recorded. In many cases, the real-time monitoring and locating of these events are essential to production decisions. Conventional methods face considerable drawbacks. For example, traveltime based methods require traveltime picking; migration methods, on the other hand, require many waveﬁeld modeling applications. These human interaction based pickings or waveﬁeld simulations face severe issues when too many passive sources need to be located, which is common in shale gas explorations. A purely automatic method with no human interactions and less computational cost is necessary. Recently, machine learning has been utilized for this task, whether to identity passive seismic events, or to locate their sources once they are identiﬁed and picked. We propose to use an artiﬁcial neural network to directly map seismic data, without any picking, to locations of potential seismic events. A visual geometry group (VGG) neural network is trained on synthetic acoustic data, corresponding to known sources, to provide predictions of new passive source locations, and other source features such as source wavelet peak frequencies, amplitudes and the number of sources within the data segment. To reduce the size of the input-to-the-network seismic data, we correlate the traces with the central trace to allow the network to focus on the curvature of the input data. We train the network to handle both single and double events that might be included in the correlation window. An initial application of the approach on a simple V ( z ) model demonstrates its potential.
Temporal Pole Responds to Subtle Changes in Local Thyroid Hormone Signaling

Abstract To study thyroid hormone (TH) signaling in the human brain, we analyzed published microarray data sets of the temporal pole (Brodmann area 38) of 19 deceased donors. An index of TH signaling built on the expression of 19 well known TH-responsive genes in mouse brains (T3S+) varied from 0.92 to 1.1. After Factor analysis, T3S+ correlated independently with the expression of TH transporters (MCT8, LAT2), TH receptor (TR) beta and TR coregulators (CARM1, MED1, KAT2B, SRC2, SRC3, NCOR2a). Unexpectedly, no correlation was found between T3S+ vs DIO2, DIO3, SRC1, or TRα. An unbiased systematic analysis of the entire transcriptome identified a set of 1649 genes (set #1) with strong positive correlation with T3S+ (r > 0.75). Factor analysis of set #1 identified 2 sets of genes that correlated independently with T3S+, sets #2 (329 genes) and #3 (191 genes). When processed through the Molecular Signatures Data Base (MSigDB), both sets #2 and #3 were enriched with Gene Ontology (GO)-sets related to synaptic transmission and metabolic processes. Ranking individual human brain donors according to their T3S+ led us to identify 1262 genes (set #4) with >1.3-fold higher expression in the top half. The analysis of the overlapped genes between sets #1 and #4 resulted in 769 genes (set #5), which have a very similar MSigDB signature as sets #2 and #3. In conclusion, gene expression in the human temporal pole can be assessed through T3S+ and fluctuates with subtle variations in local TH signaling.
Intention to Use Exoskeletons in Geriatric Care Work: Need for Ergonomic and Social Design

In this research, we investigate user experiences with the Laevo exoskeletons in geriatric work. We introduce two studies where Finnish nurses used exoskeletons and identify the requirements and potential restrictions for using exoskeletons in care context. Our results show that nurses’ intentions to use the exoskeletons were mostly associated with perceived usefulness, ergonomics, and enjoyment of use. Also, social environment issues, such as other people’s reactions, are important considerations. Exoskeleton use has varying requirements depending on where it will be implemented. Thus, the end users’ ideas for the design are crucial in enabling exoskeleton use in different sectors of work.

Coronary Artery Disease Screening Using CT Coronary Angiography.

BACKGROUND: The increased utility of CT coronary angiography (CTCA) in cardiovascular screenings of aircrew has led to the increased detection of asymptomatic coronary artery disease (CAD). A systematic review of studies relevant to the interpretation of CTCA for the occupational fitness assessment of high-risk vocations was performed, with findings used to describe the development of a pathway for the aeromedical disposition of military aviators with asymptomatic CAD.METHODS: Medline was searched using the terms CT coronary angiogram and screening and prognosis. The inclusion criteria were restricted to study populations ages > 18 yr, were asymptomatic, were not known to have CAD, had undergone CTCA, and with their associations with major adverse cardiovascular events (MACE) and other relevant cardiac outcomes reported.RESULTS: Included in this systematic review were 10 studies. When compared to subjects with no or nonobstructive CAD, those with obstructive CAD on CTCA had hazard ratios (HR) for cardiac events ranging from 1.42 to 105.48. Comparing subjects with nonobstructive CAD and those without CAD on CTCA, a lower HR of 1.19 for cardiac events was found. The annual event rates of subjects with no CAD on CTCA were extremely low, ranging from 0 to 0.5%. CONCLUSIONS: Based on the findings, we suggest that CTCA should only be performed in aircrew with higher cardiac risk profiles. Those found to have no CAD or minimal CAD (i.e., 25% stenosis) in a non-left main coronary artery on CTCA can be returned to flying duties. All other results should be further evaluated with an invasive angiogram.Cheong RWL, See B, Tan BBC, Koh CH. Coronary artery disease screening using CT coronary angiography.

Distribution and abundances of diazotrophs and microbial nutrient limitations in the North Atlantic Ocean

The diversity and abundances of diazotrophic organisms were determined in field samples from the Atlantic Ocean. A nested PCR technique, amplifiying the structural nifH gene of nitrogenase, and subsequent phylogenetic analysis was used to determine diazotroph diversity. The abundances of seven diazotrophic phylotypes were estimated by real-time PCR. TaqMan qPCR primers and probes were designed to target four cyanobacterial (one filamentous and three unicellular), two putative gamma-proteobacterial, and one putative anaerobic nifH phylotype(s). Over half of the total nifH copies detected were filamentous, indicating that this is an important diazotroph. The potential for diazotrophy above 30°N and at nitrate concentrations above 0.5 µM was demonstrated by the presence of nifH genes under these conditions. Results of nutrient addition bioassay experiments showed that nitrogen fixation was phosphorus and iron co-limited, however increases in nifH copy numbers was seen only with the addition of Saharan dust indicating that Saharan dust influences diazotroph distributions. A laboratory experiment conducted with Trichodesmium erythraeum demonstrated that this organism can utilize iron from Saharan dust. Bioassay experiments also revealed that primary production was nitrogen limited and heterotrophic bacterial production was nitrogen and phosphorus co-limited throughout the Northern Atlantic Ocean, emphasizing the important role diazotrophs have by providing fixed nitrogen in this system.
