Analysis of anomaly detection method for Internet of things based on deep learning

With the rapid development of the Internet of things technology, the connection between things and people is realized in a real sense, and the intelligent perception, recognition, and management of goods and processes are also achieved. Cloud computing, as one of the core technologies of the Internet of Things, has been widely used in online services of various networks, but the generation of abnormal data will affect the service performance of cloud computing systems. Therefore, effective detection of abnormal data is of great significance to improve the efficiency of the system. Because of the large amount of data and nonlinear distribution in the cloud computing system, the accuracy of traditional methods is low. Based on this, this article proposes a deep learning algorithm based on recurrent neural network (RNN) to implement anomaly detection in the cloud computing system. Based on the basic principle of the RNN algorithm, this article analyses the properties and defects of the activation functions commonly used in RNN, and then improves the RNN algorithm, so as to realize the effective detection of abnormal data in cloud computing system. The simulation results show that the optimized RNN deep learning algorithm for anomaly detection in cloud computing system can effectively improve the detection success rate, effectively reduce the detection time and cost, show strong robustness, and effectively improve the online service efficiency of the Internet of things technology.
Toxicity of emamectin benzoate to mallard duck and northern bobwhite quail

Nineteen‐ to 26‐week‐old mallard ducks (Anas platyrhynchos) were found to be more sensitive than northern bobwhite quail (Colinus virginianus) of the same age to single oral doses of emamectin benzoate. The resulting median lethal dose values determined for emamectin benzoate to mallard duck and northern bobwhite quail were 76 and 264 mg/kg, respectively, and the no‐observed‐effect levels were <25 and 25 mg/kg, respectively. Exposure of 10‐d‐old mallard ducks and bobwhite quail to emamectin benzoate in feed also gave relatively high median lethal concentration (LC50) values of 570 and 1,318 ppm, respectively, and no‐observed‐effect concentrations of 20 and <125 ppm, respectively. Clinical signs of toxicity included lethargy, ruffled appearance, loss of righting reflex, and reduction in food consumption; these signs appeared to be fully reversible with cessation of exposure. The maximum residue level of emamectin benzoate found in field‐treated foliage is several‐fold (7,125–16,475) less than these LC50 values. Because the likely primary route of emamectin benzoate exposure to birds is through treated food in the diet, these results indicate minimal acute risk to avians from emamectin benzoate use in crop protection.
Essential Oil Variation in Thymus daenensis subsp. daenensis Cleak Populations

Abstract The chemical composition of the essential oils in 11 populations of Thymus daenensis subsp. daenensis Cleak was evaluated using GC and GC/MS. Carvacrol, thymol and geraniol were found as the main constituents in the oils of the tested populations. Variation of the oils in populations was subjected to cluster analysis and three different chemotypes including carvacrol (47.3–80.1%), thymol (53.1–72.2%) and geraniol (65.6–75.7%) were identiified. Other important components were β-caryophyllene (1.7–9%), p-cymene (0.1–10.9%) and γ-terpinene (0.1–7.8%). Although Thymus is known as having high thymol content in its oil, it is revealed that T. daenensis subsp. daenensis has also a high potential for carvacrol and geraniol constituents in the oil.
Black fungal colonies as units of survival: hyphal mycosporines synthesized by rock-dwelling microcolonial fungi

Microcolonial fungi, long-living modified mycelia frequently occurring on desert and pseudodesert rock surfaces, are exposed to strong ultraviolet (UV) radiation, desiccation, and nutrient scarcity. They lack ascospores; all their cells grow by mitotic cell divisions and possess a thick melanized cell wall. Colonies of several randomly selected microcolonial strains were cultured and their structure was examined by cryo-scanning and transmission electron microscopy. Extracts of nine strains were analyzed by high performance liquid chromatography interfaced with mass spectrometry for the presence of mycosporines. These UV-absorbing compounds, common in spores and other survival structures, were thought to be limited to reproductive morphogenesis and unknown in growing hyphae. Mycosporines were present in eight of the strains, and mycosporine-glutaminol-glucoside (λmax = 310 nm; MH+ = 465) was the major mycosporine detected. Mycosporines present in the vegetative fungal microcolonies may be associated with the high survival potential, nonexpansive intracolonial growth, and longevity of these fungi. Intrahyphal growth and recolonization of old cells by new ones were observed in all strains investigated. Resume : Les champignons micro-coloniaux, constitues de myceliums longivives modifies, se retrouvent frequemment sur des surfaces rocheuses en milieux desertiques et pseudo-desertiques; ils sont exposes a de fortes radiations UV, au dessechement et a la rarete des nutriments.

Combining ability in early Indian cauliflower

Summary Six early maturing inbreds from maturity group I of Indian cauliflowers were selected and diallol crosses were made to study the combining ability of inbreds and identify the desirable parent(s) for hybridization. Seven characters, i.e. curd weight, curd size index, maturity, plant height, number of leaves, leaf size index and plant spread were studied both in F1 and F2 generations. Though the estimates of both general and specific combining ability variances were highly significant for all the characters, the magnitudes of general combining ability variances were higher than that of specific combining ability variances. The performance of the inbreds was in general associated with their general combining ability effects. The inbred 103 was found to be best combiner for all the characters and the cross 105 x 108 showed maximum yield potential.
Urban Network and Regions in China: An Analysis of Daily Migration with Complex Networks Model

This paper analyzed urban network and regions in China using a complex network model. Data of daily migration among 348 prefectural-level cities from the Baidu Map location-based service (LBS) Open Platform were used to calculate urban network metrics and to delineate boundaries of urban regions. Results show that urban network in China displays an obvious hierarchy in terms of attracting and distributing population and controlling regional interaction. Regional integration has become increasingly prominent, as administrative boundaries and natural barriers no longer have strong impacts on urban connections. Overall, 18 urban regions were identified according to urban connectivity, and the degree of urban connection is higher among cities in the same urban region. Due to geographical proximity and close interaction, several provincial capital cities form an urban region with cities from neighboring provinces instead of those from the same province. Identification of urban region boundaries is of significant importance for sustainable development and policymaking on the demarcation of urban economic zones, urban agglomerations, and future adjustment of provincial administrative boundaries in China.
Increased Organic Carbon Burial in Northern Florida Mangrove‐Salt Marsh Transition Zones

Blue carbon habitats like salt marshes and mangroves bury large amounts of carbon with limited area; however, they also are increasingly susceptible to current climate change. Combined effects of rising temperatures, decreasing freeze frequencies, and increasing sea level rise rates are resulting in mangrove replacement of salt marshes along the southern United States. Surface soils analyzed here from wetlands along northern Florida Atlantic and Gulf Coasts showed higher apparent sedimentation rates in mangrove‐dominated sites (1.5–3.2 mm yr−1) and where mangroves are migrating into the marsh (termed transition sites, 2.3–3.8 mm yr−1). Average carbon burial rates were higher in transition sites for both coasts (27–47 g C·m−2·yr−1) compared to the respective mangrove (10–22 g C·m−2·yr−1) and salt marsh (4–7 g C·m−2·yr−1) sites. Lignin biomarker data (Λ‐6, Λ‐8, and C/V) indicated that mangrove and transition sites had higher lignin inputs from woody vascular plants compared to salt marsh sites, which may slow decadal‐ to centennial‐scale decay. Higher amino acid concentrations in mangrove soils relative to mangrove biomass (1.8–2.3 mmol g C−1 vs. 0.2–0.9 mmol g C−1) and lower C/N indicated that these mangrove sites receive higher algal inputs than the transition and salt marsh sites, attributed to greater tidal inundation in the mangrove sites given their position near the shoreline. Overall, increased accretion, carbon burial, and lignin in mangrove transition sites indicate that this migration may increase carbon burial and increase the stability and residence time of buried soil carbon. Future studies on mangrove migration in northern Florida can verify this through replication and elevation analysis.
Llamamientos feministas en Twitter: ideología, identidad colectiva y reenmarcado de símbolos en la huelga del 8M y la manifestación contra la sentencia de 'La Manada'.

En este articulo pretendemos acercarnos al estudio de los movimientos sociales y en particular a las manifestaciones colectivas relacionadas con el genero. Partiendo de un acercamiento constructivista (Pujante, 2017) a los estudios de discurso, utilizaremos como objeto de analisis un breve corpus de interacciones en la red social Twitter en los que se llama a la movilizacion colectiva por cuestiones de discriminacion y violencia de genero, asi como ejemplos en los que se responde a dicha movilizacion tanto de manera positiva como negativa. En concreto nos centraremos en dos acontecimientos: el 8 de marzo y las manifestaciones y protestas populares que tuvieron lugar tras el llamado juicio a 'La Manada'. Siguiendo un acercamiento constructivista y fundamentalmente basado en los aspectos multimodales, en este estudio se pretende responder a tres preguntas: i) como se construye la identidad colectiva que protesta contra la discriminacion de genero, ii) que procesos de re-contextualizacion discursiva se producen entre distintos tipos de manifestacion discursiva y iii) que categorias semioticas son analizables cuando el marco retorico-constructivista se aplica al estudio de las redes sociales.
Design and Validation of a Minimal Complexity Algorithm for Stair Step Counting

Wearable sensors play a significant role for monitoring the functional ability of the elderly and in general, promoting active ageing. One of the relevant variables to be tracked is the number of stair steps (single stair steps) performed daily, which is more challenging than counting flight of stairs and detecting stair climbing. In this study, we proposed a minimal complexity algorithm composed of a hierarchical classifier and a linear model to estimate the number of stair steps performed during everyday activities. The algorithm was calibrated on accelerometer and barometer recordings measured using a sensor platform worn at the wrist from 20 healthy subjects. It was then tested on 10 older people, specifically enrolled for the study. The algorithm was then compared with other three state-of-the-art methods, which used the accelerometer, the barometer or both. The experiments showed the good performance of our algorithm (stair step counting error: 13.8%), comparable with the best state-of-the-art (p > 0.05), but using a lower computational load and model complexity. Finally, the algorithm was successfully implemented in a low-power smartwatch prototype with a memory footprint of about 4 kB.
GISS Model E2.2: A Climate Model Optimized for the Middle Atmosphere—Model Structure, Climatology, Variability, and Climate Sensitivity

We introduce a new climate model (GISS E2.2) that has been specially optimized for the middle atmosphere and whose output is being contributed to the CMIP6 archive. The top of the model is at a geopotential altitude of 89 km, and parameterizations of moist convection and various forms of gravity wave drag based on tropospheric processes are chosen specifically for this optimization. We first evaluate the model in its configuration as a coupled atmosphere‐chemistry model with respect to its simulation of the mean state of the middle atmosphere, from the mesosphere down through the upper troposphere/lower stratosphere. Then we assess its use as a coupled atmosphere‐ocean climate model by exploring its mean ocean climatology. To evaluate its variability, we report on its simulation of the primary modes in the troposphere, stratosphere, and ocean. Two climate change simulations are presented, the responses to instantaneous increases of 2xCO2 and 4xCO2, run with two different ocean models. Sensitivity studies are performed to illustrate the effect of parameterizations on the model results. We compare these results to the lower vertical resolution/top GISS Model E2.1, whose output has also been submitted to CMIP6. The different choices made for these models are explored. It is shown that important improvements in the circulation above and below the tropopause can be obtained when attention is paid to representation of middle atmosphere processes in climate model development.
Structure-texture image decomposition using a new non-local TV-Hilbert model

Combining the advantages of the non-local total variation (TV) and the Gabor function, a new Gabor function based non-local TV-Hilbert model is presented to separate the structure and texture components of the image. Computationally, by introducing the dual form of the non-local TV, the authors reformulate the non-local TV-Hilbert minimisation problem into a convex–concave saddle-point problem. In the aspect of solving algorithm, by transforming the Chambolle–Pock's first-order primal–dual algorithm into a different equivalent form. The authors propose a proximal-based primal–dual algorithm to solve the convex–concave saddle-point problem. At last, experimental results demonstrate that the proposed new model outperforms several existing state-of-the-art variational models.
Machine-enabled inverse design of inorganic solid materials: promises and challenges

Developing high-performance advanced materials requires a deeper insight and search into the chemical space. Until recently, exploration of materials space using chemical intuitions built upon existing materials has been the general strategy, but this direct design approach is often time and resource consuming and poses a significant bottleneck to solve the materials challenges of future sustainability in a timely manner. To accelerate this conventional design process, inverse design, which outputs materials with pre-defined target properties, has emerged as a significant materials informatics platform in recent years by leveraging hidden knowledge obtained from materials data. Here, we summarize the latest progress in machine-enabled inverse materials design categorized into three strategies: high-throughput virtual screening, global optimization, and generative models. We analyze challenges for each approach and discuss gaps to be bridged for further accelerated and rational data-driven materials design.
Corrosion and microstructure of as-cast magnesium alloy AM60-based hybrid nanocomposite

ABSTRACT Two types of Mg alloy AM60-based composites containing (1) only 7 vol.% Al2O3 Fibre and (2) both 7 vol.% Al2O3 Fibre + 3 vol.% Al2O3 nano-Particle, named 7FC and MHNC-7F3NP, respectively, as well as the unreinforced matrix alloy AM60 were prepared by using the preform-squeeze casting technique. The microstructure of the matrix alloy AM60 characterised by optical microscopy (OM), scanning electron microscopy (SEM) and X-ray energy dispersive spectroscopy (EDS) consisted of primary α-Mg grains, eutectic β-Mg17Al12 phases and Al-Mn intermetallics, of which distribution were different from those in the composites. The reinforcement introduction refined the matrix grain structure of the composites significantly. The corrosion behaviours of the 7FC and MHNC-7F3NP composites and the matrix alloy were investigated by using the potential-dynamic polarisation test in 3.5 wt. % NaCl aqueous solution. Compared with the matrix alloy, the introduction of micron-sized alumina fibres decreased the corrosion resistance of the matrix alloy AM60 considerably due to the presence of excessive interfaces, while the high density of grain boundaries and the absence of noble precipitates such as β-Mg17Al12 phases and Al-Mn intermetallics at the grain boundaries in the composites should also be somewhat responsible for their poor corrosion resistance. The addition of the nano-sized particles led to almost no further reduction in the corrosion resistance of the MHNC-7F3NP.
Molecular phylogeny of protobranch bivalves and systematic implications of their shell microstructure

Higher systematics and evolutionary history of Protobranchia, a subclass of Bivalvia, have long been controversial due to paucity of prominent shell characters and difficulties in collecting live material for diverse taxa. Here, we evaluate the reliability of shell microstructure for protobranch higher systematics by reconstructing a molecular phylogeny of the subclass. Relationships were assessed using the nuclear (18S rRNA, 28S rRNA and histone H3) and mitochondrial (16S rRNA and cytochrome c oxidase subunit 1) gene sequences from 89 in‐group species. Maximum likelihood reconstruction with the nuclear markers recognized five superfamilies (Nuculoidea, Solemyoidea, Manzanelloidea, Nuculanoidea and Sareptoidea) as the in‐group clades of the monophyletic Protobranchia. Sareptoidea is herein redefined to comprise Sarepta and Setigloma in the sole family Sareptidae, whereas Pristigloma and its monotypic Pristiglomidae are transferred from this superfamily to Nuculanoidea, both in the order Nuculanida. Mapping of shell microstructure characters on the tree confirmed their conservativeness at superfamily level when only living species were taken into account. The Nuculoidea have shells with the outer prismatic and middle/inner nacreous structures; Solemyoidea are characterized by either the radially elongate simple prismatic structure or the reticulate structure in the outer shell layer; Manzanelloidea, Nuculanoidea and Sareptoidea have shells of homogeneous, fibrous prismatic and/or fine complex crossed lamellar structures, all of which lack large structural units. Our Bayesian time calibration, on the contrary, suggested frequent loss of nacre in the Paleozoic and Mesozoic history of Protobranchia, at least once each in Nuculoidea, Manzanelloidea, Solemyoidea and Sareptoidea in the Paleozoic, and perhaps multiple times in Nuculanoidea by the Mesozoic.
Design of Potent β-Lactamase Inhibitors by Phage Display of β-Lactamase Inhibitory Protein*

β-Lactamase inhibitory protein (BLIP) binds tightly to several β-lactamases including TEM-1 β-lactamase (Ki 0.1 nm). The TEM-1 β-lactamase/BLIP co-crystal structure indicates that two turn regions in BLIP insert into the active site of β-lactamase to block the binding of β-lactam antibiotics. Residues from each turn, Asp49 and Phe142, mimic interactions made by penicillin G when bound in the β-lactamase active site. Phage display was used to determine which residues within the turn regions of BLIP are critical for binding TEM-1 β-lactamase. The sequences of a set of functional mutants from each library indicated that a few sequence types were predominant. These BLIP mutants exhibitedKi values for β-lactamase inhibition ranging from 0.01 to 0.2 nm. The results indicate that even though BLIP is a potent inhibitor of TEM-1 β-lactamase, the wild-type sequence of the active site binding region is not optimal and that derivatives of BLIP that bind β-lactamase extremely tightly can be obtained. Importantly, all of the tight binding BLIP mutants have sequences that would be predicted theoretically to form turn structures.

Static and Dynamic Magnetic Properties of FeGa/FeNi (FeNi/FeGa) Bilayer Structures

FeGa/FeNi bilayer structures with different deposition order were fabricated by the electrodeposition method on indium tin oxide (ITO) substrates. The structure, morphology, static and dynamic magnetic properties of FeGa/FeNi (FeNi/FeGa) films were investigated. The bilayer structures exhibit extremely various magnetic properties with different deposition order which could be attributed to the different coupling interaction in the interface. When FeGa is on top, the bilayer structures show lower coercivity than when FeNi is on top. Meanwhile, increase of the proportion of FeNi in the bilayer structure could affect the Hc and Mr/Ms. The ferromagnetic resonance peak of FeGa on top moves to a high field compared with FeNi on top. Moreover, FeGa on top shows improved complex permeability and a clear resonant phenomenon of the magnetization. These properties make FeGa/FeNi bilayer structure a potential candidate for high-frequency application.
Long‐term Survival of Retina Optic Nerve Section in Adult Ganglion Cells Following bcl‐2 Transgenic Mice

The bcl‐2 gene codes for a protein that acts as a powerful inhibitor of active cell death. Since the transection of the optic nerve in adult mammalians starts a massive process of degeneration in retinal ganglion cells, we investigated whether the overexpression of bcl‐2 in adult transgenic mice can protect the axotomited ganglion cells. We performed intracranial optic nerve transection on both wild type and transgenic adult mice, and we tested cell survival 2 or 3.5 months after axotomy. The percentage of surviving ganglion cells after optic nerve section was computed by combining the counts of the optic nerve fibres in intact nerves with the cell density measures of the ganglion cell layer of axotomized retinae. From these data we found that in transgenic mice˜65% of ganglion cells survived 3.5 months after axotomy. In contrast, 2 months after surgery, <10% of ganglion cells were left in wild type retinae. We have also examined the morphology and fine structure of the proximal stump of the sectioned optic nerves by light and electron microscopy. In the transgenic mice a very large number of axons survived after surgery and they still exhibited fairly normal morphology and ultrastructure. On the other hand the wild type transected nerves had only a few visible axons that displayed clear signs of degeneration. We conclude that the overexpression of Bcl‐2 protein in central neurons is a very effective strategy to ensure long‐term survival in axotomized cells.
