Fair Network Division of Nano-satellite Swarms

We address the problem of partitioning a network of nano-satellites to fairly distribute the network load under energy consumption constraints. The study takes place in a context where a swarm of nano-satellites orbits the Moon and works as, but not limited to, a distributed radio-telescope for low-frequency radio interferometry. During an interferometry mission, each nano-satellite collects observation data, then shares them with the other swarm members to compute a global image of space. However, the simultaneous transmission of large volumes of data can cause communication issues by overloading the radio channel, leading to potential packet loss. In this context, we investigate three division algorithms based on graph sampling techniques. We prove that random walk-based algorithms overall perform the best in terms of conservation of graph properties and fairness for group sizes down to 10% of the original graph.
Confucian Culture and Corporate True Surplus Management: Facilitation or Inhibition?——Based on the Perspective of Internal and External Monitoring Mechanisms of Listed Companies

As the requirements for quality of accounting information continue to be rigorous, corporate surplus management is gradually biased toward using real business for it. Real surplus management behavior is covert and private, and can damage the long-term value of enterprises, so how to curb real surplus management behavior is an important issue worth studying. This paper selects a sample of listed companies in Shanghai and Shenzhen A-shares from 2015- 2019 to test the influence of Confucianism. This paper selects a sample of listed companies in Shanghai and Shenzhen A-shares from 2015-2019 to test the influence of Confucian culture on corporate true surplus management from an informal institutional perspective.

Optical Switching Mechanism Based SD-OCT for in Vivo Anterior and Retinal Chamber Imaging

— In this paper, a technique is developed that can take the depth corresponding to two times depth range of the existing system by including an optical switch in spectral domain optical coherence tomography (SD-OCT) system. The results were obtained by conducting an animal experiment. In order to verify the effectiveness of this technology, optical switch was employed to acquire OCT images sequentially at various depths, to range from the cornea to the retina of guinea pig. Optical switch has a role to match the focus at multiple points of the sample arm for acquiring data of the anterior and the posterior chambers of the eye, and it has the capability of recording the images in real-time.
Early ontogeny-related changes o f the fatty acid composition in the Percichthyid fishes trout cod, M accullochella m acquariensis and Murray cod, M.

— Changes in the fatty acid profiles of the Percichthyid fish trout cod, Maccullochella macquariensis (Cuvier), and Murray cod, M. peelii peelii (Mitchell), two Australian native freshwater fish species, were investigated during early development from egg to yolk-sac-resorbed larval stage. In the two Percichthyid fishes polyunsaturated fatty acids (PUFA) accounted for more than 50 % of the 19 quantified fatty acids in total lipid. The fatty acids that occurred in the highest abundance in both trout cod and Murray cod, in all developmental stages, in order, were docosahexaenoic acid [DHA 22:6(n-3)], arachidonic acid [AA 20:4(n-6)], oleic acid [18:1 (n-9)] and palmitic acid (16:0), all of which exceeded 100 µg per mg total lipid in most instances. The ratio of 22:6(n-3) to eicosapentaenoic acid- 20:5(n-3) in eggs of trout cod and Murray cod was 5.4:1 and 7.3:1, respectively, and remained almost unchanged through development, and was considerably higher than the 2:1 ratio generally reported for fish eggs. In trout cod, 11 of the 19 fatty acids in total lipid decreased during the transformation from egg to yolk-sac-resorbed larva. In Murray cod, only 16:l(n-7) showed a significant decrease whilst 20:4(n-6) increased significantly with development. Overall, there was a tendency in both species to conserve n-3 and n-6 series highly unsaturated fatty acids (HUFA), suggesting their essentiality in first feeding larvae. These observations are discussed in relation to the feeding habits of trout cod and Murray cod, which are top order, freshwater carnivores. © Ifremer/Cnrs/Inra/Ird/Cemagref/Elsevier, Paris Fatty acids / eggs / larvae / yolk-sac resorption / freshwater fish
Sparse regularization on thin grids I: the Lasso

This article analyzes the recovery performance in the presence of noise of sparse ℓ1 regularization, which is often referred to as the Lasso or Basis-Pursuit. We study the behavior of the method for inverse problems regularization when the discretization step size tends to zero. We assume that the sought after sparse sum of Diracs is recovered when there is no noise (a condition which has been thoroughly studied in the literature) and we study what is the support (in particular the number of Dirac masses) estimated by the Lasso when noise is added to the observation. We identify a precise non-degeneracy condition that guarantees that the recovered support is close to the initial one. More precisely, we show that, in the small noise regime, when the non-degeneracy condition holds, this method estimates twice the number of spikes as the number of original spikes. Indeed, we prove that the Lasso detects two neighboring spikes around each location of an original spike. While this paper is focussed on cases where the observations vary smoothly with the spikes locations (e.g. the deconvolution problem with a smooth kernel), an interesting by-product is an abstract analysis of the support stability of discrete ℓ1 regularization, which is of an independent interest. We illustrate the usefulness of this abstract analysis to analyze for the first time the support instability of compressed sensing recovery.
(2016) Mediating claims through critical anthropomorphism. Animal Sentience 3(17)

: Key’s (2016) discussion of his claim that fish do not feel pain ignores the history of attempts to study the attribution of mental states to other species. Although willing to accept that mammals feel pain, Key claims that fish lack the mammalian neural mechanisms underlying pain and are unconscious of their experiences. Consequently, we do not need to be overly concerned about fishing practices that would otherwise be viewed as painful. Key uses a flawed anthropomorphic lens. All attributions of mental events to organisms other than oneself involve inferences derived from anthropomorphic processes through which we process physiological and behavioral data. To do this effectively we need to employ a critical anthropomorphism incorporating our experiences as sentient beings along with diverse scientific findings, avoiding claims that some types of data always trump other considerations.
Research on the Hydraulic Characteristics of Island Fishways by Experimental and Numerical Methods

With the development of hydraulic structures, rivers are becoming fragmented, and their connectivity is greatly affected. Important migratory routes through which fish complete their life processes are hindered. In severe cases, it may lead to the extinction of fish species. As facilities commonly used to assist fish upstreaming, fishways are significant for environmental remediation and have received attention from different scholars. This article proposed a new type of fishway, inspired by Tesla valves with obstructing reverse flow characteristics and classic fishway structures. Due to its characteristic of introducing a water-blocking island structure, it was denominated as an island-style fishway. This work studied an island fishway through a combination of physical models and numerical simulations. The results show that this fishway could achieve various flow patterns suitable for fish migration, and the flow rate control was stable. This study also explored the impact of island spacing arrangement on the turbulent structure of the pool chamber. It was found that when the island distance is set at 1.5d, indicators such as flow velocity and turbulent kinetic energy could achieve significant control effects. However, inappropriate d values might cause adverse effects. This research could provide reference ideas for the design of new fishways.
Issue by screening 47 pairs of monozygotic twins discordant for CFS using a sensitive PCR assay

The recent debate regarding the possible involvement of xenotropic murine leukemia virus-related virus (XMRV) in chronic fatigue syndrome (CFS) in humans has been intense due to the conflicting results from different studies and the unclear origin of the XMRV virus. In this study, we have addressed this issue by screening 47 pairs of monozygotic twins discordant for CFS using a sensitive PCR assay. The results are clearly negative for all samples. This is consistent with studies showing no evidence for the involvement of XMRV in CFS and supports the possibility that previous positive studies could be caused by laboratory artifacts.
They’re the same picture: a software-verification flow adapted for hardware verification

Software verification and hardware verification are traditionally considered separate enterprises, but our experience suggests that activities in software verification have natural counter parts in hardware verification and vice versa. We believe that there ought to be more technology transfer between the two. In this text, we describe one such instance of technology transfer from the world of interactive theorem proving: we outline how we have adapted the functional-programming-based software-verification flow of the CakeML project to a hardware-verification flow for Verilog. The work described here has been carried out in the HOL4 interactive theorem prover.
Does India need a different rice ecosystem to harness the export advantages and manage the virtual water exports?

The present study assessed the virtual water trade and comparative advantages in rice exports. It suggests realigning the Indian rice ecosystem based on the demand–supply gap, groundwater exploitation, productivity growth and untapped productivity potential. It also advocates the phased shifting of acreage under common (non-basmati) rice production to potential regions identified as suitable. The proposed shifting of cultivation will lead to achieving a sustainable rice ecosystem, conserving the natural resource base and reducing risk in terms of environmental and economic factors. Emerging practices such as dry direct-seeded rice, and the system of rice intensification could be effectively used for sustainable rice ecosystem in India.
Self-enhanced aerosol–fog interactions in two successive radiation fog events in the Yangtze River Delta, China: A simulation study

Aerosol–fog interactions (AFIs) play pivotal roles in the fog cycle. However, few 15 studies have focused on the differences in AFIs between two successive radiation fog events and the underlying mechanisms. To fill this knowledge gap, our study simulates two successive radiation fog events in the Yangtze River Delta, China, using the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem). Our simulations indicate that AFIs in the first fog (Fog1) promote AFIs in the second one (Fog2), resulting in higher number 20 concentration, smaller droplet size, larger fog optical depth, wider fog distribution, and longer fog lifetime in Fog2 than in Fog1. This phenomenon is defined as the self-enhanced AFIs, which are related to the following physical factors. The first one is conducive meteorological conditions between the two fog events, including low temperature, high humidity and high stability. The second one is the feedbacks between microphysics and radiative cooling. A higher 25 fog droplet number concentration increases the liquid water path and fog optical
Quantum critical nematic fluctuations and spin excitation anisotropy in the iron pnictides

Quantum criticality in iron pnictides involves both the nematic and antiferromagnetic degrees of freedom, but the relationship between the two types of fluctuations has yet to be clarified. Here we study this problem within an effective Ginzburg-Landau theory for both channels in the presence of a small external uniaxial potential, which breaks the $C_4$-symmetry in the B$_{1g}$ sector. We establish an identity that connects the spin excitation anisotropy, which is the difference of the dynamical spin susceptibilities at $\vec{Q}_1=\left(\pi,0\right)$ and $\vec{Q}_2=\left(0,\pi\right)$, with the dynamical magnetic susceptibility and static nematic susceptibility. Using this identity, we introduce a scaling procedure to determine the dynamical nematic susceptibility in the quantum critical regime, and illustrate the procedure for the case of the optimally Ni-doped BaFe$_2$As$_2$ [Y. Song et al., Phys. Rev. B 92, 180504 (2015)]. The implications of our results for the overall physics of the iron-based superconductors are discussed.
Testing the influence of light on nitrite cycling in the eastern tropical North Pacific

Light is considered a strong controlling factor on nitrification rates in the surface ocean. Previous work has shown that ammonia oxidation and nitrite oxidation may be inhibited by high light levels, yet active nitrification has been measured in the 10 sunlit surface ocean. While it is known that photosynthetically active radiation (PAR) influences microbial nitrite production and consumption, the level of inhibition of nitrification is variable across datasets. Additionally, phytoplankton have light-dependent mechanisms for nitrite production and consumption that co-occur with nitrification around the depths of the primary nitrite maximum (PNM). In this work, we experimentally determined the direct influence of light level on net nitrite production, including all major nitrite cycling processes (ammonia oxidation, nitrite oxidation, nitrate reduction, nitrite uptake) in microbial communities 15 collected from the base of the euphotic zone. We found that although ammonia oxidation was inhibited at the depth of the PNM and was further inhibited by increasing light at all stations, it remained the dominant nitrite production process at most stations and treatments, even up to 25% surface PAR. Nitrate addition did not enhance ammonia oxidation in our experiments, but may have increased nitrate and nitrite uptake at a coastal station. In contrast to ammonia oxidation, nitrite oxidation was not clearly inhibited by light, and sometimes even increased at higher light levels. Thus, accumulation of nitrite at the PNM may be modulated by 20 changes in light, but light perturbations did not exclude nitrification from the surface ocean. Nitrite uptake and nitrate reduction were both enhanced in high light treatments relative to low light, and in some cases showed high rates in the dark. Overall, net nitrite production rates of PNM communities were highest in the dark treatments.
PLANT NUTRIENT DEFICIENCY USING MOBILENET

: Agricultural systems rely on adequate water, sunlight, and nutrient uptake for plants. Different plants have different amounts of nutrients, known as macronutrients or micronutrients. Plant growth and development can be affected by macronutrient deficiencies. Nutrient deficiencies are a common condition that can affect plants if not treated promptly. Monitoring for defects is manual and requires more effort, especially in large areas. The rapid development of technology has made it possible to build systems to detect nutrient deficiencies in plants. Missing plants are detected by MobileNet, and the situation is diagnosed from plant images. To determine nutrient deficiencies, plant leaf analysis was performed for leaf condition. You can estimate which nutrients your plant's roots are getting enough of, and symptoms of deficiency can be identified by leaf colour and size. MobileNet is specifically trained for nutrient deficiencies and is used to determine if leaves exhibit symptoms related to nutrient deficiencies.
Modulation of the Intraseasonal Variability of Early Summer Precipitation in Eastern China by the Quasi-Biennial Oscillation

Using the reanalysis and multiple observations, the possible impact of the Madden-Julian Oscillation (MJO) on early summer rainfall in eastern China and its modulation by the Quasi-Biennial Oscillation (QBO) is examined. The 10 composite results show that the suppressed (enhanced) convection anomalies for MJO phases 8-1 (4-5) more concentrated over maritime continent and western Pacific during EQBO (WQBO). As a consequence, more significant wet (dry) anomalies develop in South (eastern) China during MJO phases 8-1 (4-5) configured with easterly (westerly) QBO. The enhancement and expansion of the anomalous tropical convection band do not necessarily correspond to enhancement of the extratropical circulation response to MJO phases 8-1 (4-5) configured with westerly (easterly) QBO. The anomalous high 15 (low) over the maritime continent and western Pacific associated with MJO phases 8-1 (4-5) is intensified (deepened) during easterly (westerly) QBO, leading to large southwesterly (northeasterly) anomalies in South China and coasts, carrying abundant (sparse) moisture. Two anomalous meridional circulation cells are observed for MJO phases 8-1 in the East Asia sector, with downwelling anomalies around 5–20°N, upwelling anomalies around 20–30°N, and another downwelling branch northward of 30°N, which are enhanced during easterly QBO. The anomalous meridional circulation cells are 20 reversed for MJO phases 4-5, which are stronger during westerly QBO with the anomalous downwelling
PP and PS joint inversion with a posterior constraint and with particle filtering

The Bayesian framework works well in amplitude versus offset (AVO) inversion, which merges multi-information together to generate posterior distributions of P-wave velocity, S-wave velocity and density. Most existing AVO inversion methods utilize PP reflection seismic data to predict the three elastic parameters. These methods are not usually sensitive to S-wave velocity and density, which make the inversion methods inaccurate and unstable. One way of solving these problems is to perform PP and PS joint inversion by incorporating PS seismic data. Another way is to provide a relatively accurate prior model. In this paper, we apply a particle filtering technique to produce a prior model for the PP and PS joint inversion. In the Bayesian inversion setting, the prior model works as the regularization term. Particle filtering is a Bayesian recursive method that combines prior information with observed data to provide a posterior constraint to reduce the joint inversion's uncertainty. We generate synthetic models with different signal-to-noise ratios to validate our new method. Comparisons are provided with the traditional joint inversion, which adopts the Gaussian prior model. The inversion results show that the three elastic parameters are retrieved well when the signal-to-noise ratios are high. As the signal-to-noise ratio reduces, our new method can depict more detailed changes than the traditional inversion method, and improves the inversion accuracy apparent in the target layers.
A CASE OF PSYCHOTIC DISORDER DUE TO DENGUE FEVER

Objective: This case reported highlighted psychotic disorder due to dengue fever is rare. Hence we describe a case which clearly presented with psychotic symptoms during the illness. Methods: We reported a case of psychotic disorder due to dengue fever who presented with psychotic symptoms of auditory and visual hallucination, and persecutory delusion, which had significant temporal correlation with dengue fever symptoms. There were no neurological deficits noted, no altered sensorium and cognitive impairment during the episode. He has no past and family history of mental illness and there was no evidence of encephalitis and metabolic disturbances. Results: Our case suggests that prominent psychotic symptoms can occur during an episode of dengue fever, which remitted when one recovering from dengue fever. Conclusion: We demonstrated that patients who presented with the acute onset of psychosis accompanied by symptoms of viral fever should be screened for dengue fever, particularly if the person lived in or visited the area where dengue fever is endemic.

Actual Preoperative Fasting Time; A Report From Guilan Academic Hospitals: A Cross-sectional Study

Objectives: Traditional guidelines for preoperative fasting (POF) time lead to several complications in surgery patients. However, not enough attention has been paid to the issue. This aimed of this study was to investigate the management of fasting times in Guilan academic hospitals. Materials and Methods: In this descriptive cross-sectional study, individuals from five academic referral centers enrolled the survey and questionnaires including demographic characteristics, fasting hours for liquids and solids, POF recommenders, and patient’s knowledge regarding the definition of clear liquids were completed. Results: A total of 390 individuals candidate for elective surgeries enrolled in the study, the mean age of our cases were 46.61 years. The average POF time for solids and liquids was 11.43 and 9.70 hours, respectively. 95.38% of the participants did not know a correct definition of clear liquids, which was not related to their level of education (P=0.314). A positive association was observed between age and POF times for liquids and American Society of Anesthesiologists Classification for both solids (P=0.010) and liquids (P=0.0001). Conclusions: It was found that the real POF time in our hospitals was significantly longer than the modern guidelines, and needs to be corrected.
Fractional-Order Control for Robust Position/Yaw Tracking of Quadrotors With Experiments

Quadrotors are highly maneuverable lightweight drones, which are prone to aerodynamic disturbances, vibrations, and uncertainties. These factors stand for a problem that demands robust control laws. For position tracking, the control problem is exacerbated, because the plant is underactuated in the coordinates of interest, requiring a high-performance attitude tracking to resolve underactuation. In this brief, a novel fractional-order controller is proposed by considering a well-posed map that relates the position/yaw control to the desired attitude references. The attitude control is continuous and enforces and sustains a sliding motion in finite time for exponential convergence of the tracking errors to fulfill a “virtual” position controller. The resulting closed-loop system is robust against the continuous disturbances that are not necessarily differentiable in the conventional sense. A numerical study based on the simulations is presented to analyze the advantages of the fractional actions to design a physically realizable controller, and the experiments are discussed to expose the reliability of the proposed fractional scheme implemented in an “X” configuration quadrotor.
