Oxygen Toxicity Seizure During Hyperbaric Oxygen Therapy: A Case Report

Introduction: Several neurological and other side effects and complications from hyperbaric oxygen (HBO) therapy have been described in the literature. Possible complications during HBO therapy include barotraumatic lesions, oxygen toxicity, claustrophobia, and ocular effects. Case Report: We presented a 29-year-old woman without any known history of neurological illness who had seizure during HBO therapy for Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL). Conclusion: There are several options for ISSNHL treatment which have been studied in the past with conflicting results. HBO is one of the treatment options. We presented a case with possible neurotoxic effects of HBO therapy. Clinicians should be aware of the complications of this procedure.
Spatial Ecology of the Fungal Genus Xylaria in a Tropical Cloud Forest

Fungal symbioses with plants are ubiquitous, ancient, and vital to both ecosystem function and plant health. However, benefits to fungal symbionts are not well explored, especially in non‐mycorrhizal fungi. The Foraging Ascomycete hypothesis proposes that some wood‐decomposing fungi may shift life‐history strategies to endophytism to bridge gaps in time and space between suitable substrates. To test this hypothesis we examine spatial relationships of Xylaria endophytic fungi in the forest canopy with Xylaria decomposer fungi on the forest floor. We sampled for fungi of the genus Xylaria using a spatially explicit sampling scheme in a remote Ecuadorian cloud forest, and concurrently carried out an extensive culture‐based sampling of fungal foliar endophytes. We found 36 species of Xylaria in our 0.5 ha plot, 31 of which were found to only occur as fruiting bodies. All five species of Xylaria found as endophytes were also found as fruiting bodies. We also tested the relationships of both stages of these fungi to environmental variables. Decomposer fungi were differentiated by species‐specific habitat preferences, with three species being found closer to water than expected by chance. In contrast, endophytes displayed no sensitivity to environmental conditions, such as host, moisture, or canopy cover. We found evidence of spatial linkage between life stages in two species. We also demonstrate that direct transmission of endophytes from leaves to woody substrates is possible. These results indicate that endophytism may represent one way for decomposer fungi to escape moisture limitation, and that endophytic fungi may act as sources of dispersal for decomposer fungi consistent with predictions of the Foraging Ascomycete hypothesis.
Pair separation of magnetic elements in the quiet Sun

The dynamic properties of the quiet Sun photosphere can be investigated by analyzing the pair dispersion of small-scale magnetic fields (i.e., magnetic elements). By using 25 h-long Hinode magnetograms at high spatial resolution (0. �� 3), we tracked 68490 magnetic element pairs within a supergranular cell near the disk center. The computed pair separation spectrum, calculated on the whole set of particle pairs independently of their initial separation, points out what is known as a super-diffusive regime with spectral index γ = 1.55 ± 0.05, in agreement with the most recent literature, but extended to unprecedented spatial and temporal scales (from granular to supergranular). Furthermore, for the first time, we investigated here the spectrum of the mean square displacement of pairs of magnetic elements, depending on their initial separation r0. We found that there is a typical initial distance above (below) which the pair separation is faster (slower) than the average. A possible physical interpretation of such a typical spatial scale is also provided.
Screening of SSR marker for sugar and sugar related traits

Saccharum is a complex genome characterized by high polity levels and composed of six distinct species S. officinarum, S. barberi, S. sinensi, S. spontaneum, S. robustum and S. edule. The commercial sugarcane is no longer pure Saccharum officinarum but a species hybrid, complex polyploidy with a large number of chromosomes. Sugarcane cultivars are characterized by a high polyploidy level with more than eight homologous copies of each basic chromosome of Saccharum officinarum and several copies of homologous chromosomes from S. spontaneum. This work is on screening and characterization of microsatellite or simple sequence repeat (SSR) markers which can be used as both a mapping tool, and a method for varietal identification and pedigree control in sugarcane. A molecular marker is an identifiable DNA region whose inheritance can be followed along generations. Microsatellites, also known as simple sequence repeats (SSR) or short tandem repeats (STR), are repeated sequence motifs, whose unit of repetition is between 1 and 6 bp. SSRs marker have broad range of applications, such as genome mapping and characterization, phenotype mapping, marker assisted selection of crop plants and a range of molecular biology and diversity studies. The optimum size for the primers is 18 bases, with a maximum of 24 bases. The optimum melting temperature is 55 â¦C, with a minimum of 50 â¦C and a maximum of 70 â¦C. The optimum GC content is set to 50%, with a minimum of 30% and a maximum of 70%. Screening of these SSR primers are under process for tagging of sugar trait gene among Co86011 (high sugar) and UP9530 (low sugar) parents
Breakdown of the Static Picture of Defect Energetics in Halide Perovskites: The Case of the Br Vacancy in CsPbBr3.

We consider the Br vacancy in CsPbBr3 as a prototype for the impact of structural dynamics on defect energetics in halide perovskites (HaPs). Using first-principles molecular dynamics based on density functional theory, we find that the static picture of defect energetics breaks down; the energy of the VBr level is found to be intrinsically dynamic, oscillating by as much as 1 eV on the ps time scale at room temperature. These significant energy fluctuations are correlated with the distance between the neighboring Pb atoms across the vacancy and with the electrostatic potential at these Pb atomic sites. We expect this unusually strong coupling of structural dynamics and defect energetics to bear important implications for both experimental and theoretical analysis of defect characteristics in HaPs. It may also hold significant ramifications for carrier transport and defect tolerance in this class of photovoltaic materials.
Study of a Supercritical CO 2 Power Cycle Application in a Cogeneration Power Plant

Cogeneration, or combined heat and power (CHP), is the use of a heat engine or power station to simultaneously generate electricity and useful heat. Cogeneration is considered as a thermodynamically efficient use of fuel [1]. In separate productions of electricity, some energy must be discarded as waste heat, but in cogeneration this thermal energy is put to use. Usually the CHP plant uses steam as the working fluid and has a flexible ratio of cogeneration, which depends on the season. In turn, supercritical CO2 (S-CO2) power cycles are proposed for future energy applications because of their high thermal efficiency [2]. However, the possibilities of carbon dioxide applications as working fluids for cogeneration power plants have never been published or expanded on. This paper considers several S-CO2 cycles in terms of application in a CHP plant. Combined steam/SCO2 cycles are also proposed and described, though the S-CO2 cycles are used as “bottom” cycles which only turn on when heat production is not required. The performance of several standalone cycles and combined steam/S-CO2 cycles are compared with typical steam cogeneration cycle performances. Combined steam/S-CO2 cycles, steam turbine and S-CO2 turbine features are considered.
Hip holes: kangaroo (Macropus spp.) resting sites modify the physical and chemical environment of woodland soils

Hip holes are shallow, reniform-shaped depressions found next to the trunks of many trees and shrubs in arid and semi-arid Australia. They are constructed by kangaroos ( Macropus spp.), who use them as diurnal resting sites, particularly during hot weather. Physical and chemical properties of soils in hip holes were compared with non- hole microsites adjacent to the trunk ('trunk'), microsites below the canopy ('canopy') and microsites out in the open ('open') under two trees ( Eucalyptus intertexta , Alectryon oleifolius ) and one shrub ( Dodonaea viscosa ) in a semi-arid woodland in eastern Australia. Overall, there were few effects under D. viscosa apart from a greater (10-fold) mass of litter in the hip holes compared with the trunk microsite. Hip holes under E. intertexta and A. oleifolius , however, contained six times more dung compared with the trunk microsite. For the two tree species, soils in the hip holes were significantly more erodible, as measured by aggregation levels, compared with the other microsites, but there were no significant differences in bulk density nor pH. Steady-state infiltration rates at the hip hole and trunk microsites were significantly greater than those in the open, but there was no significant hip hole effect. Soils in the hip holes contained greater levels of exchangeable calcium and magnesium ( E. intertexta ) and greater exchangeable sodium ( A. oleifolius ) compared with trunk microsites. Hip holes under E. intertexta contained approximately 68% more organic carbon, total carbon and nitrogen, and 86% more sulfur compared with trunk microsites. Similarly, hip holes under A. oleifolius contained on average 38% more organic and total carbon, and 47% more nitrogen than trunk microsites. Given the density of hip holes and their impact on soil chemistry, kangaroos are considered to be important elements in the maintenance of heterogeneity in these woodlands.
Application of Egyptian Vulture Optimization in Speech Emotion Recognition

Recognition of emotions present in human speech is a task made complicated due to incomplete knowledge of the relevant features, dependency on language, dialect and even individuals and the ambiguous meaning of term emotion itself. This work aims to study the relevant features present in human speech and infer its emotional category, making use of machine learning models. Theprime objective of this work is to analyze the presented human speech and classify it into one of the seven emotional categories-happiness, sadness, anger, boredom, anxiety, disgust, and neutral. Proposed method extracts Mel Frequency Cepstral coefﬁcients (MFCC), Chroma and Time Spectral features from Berlin EmoDB speech clips, and compares the results obtained from traditional classiﬁers to those with added nature inspired optimization technique. Egyptian Vulture Optimization Algorithm (EVOA),Grey Wolf Optimization(GWO) and Moth Flame Optimization(MFO) were applied over the mentioned feature set along with RF, KNN and SVM, and it is inferred that EVOA signiﬁcantly improves the performance metrics of mentioned algorithms over EMO-DB when applied alongside. Using GWO with SVM produced the highest classiﬁcation accuracy 90.67%.
MODELING AND ANALYSIS OF CONDUCTED ELEC- TROMAGNETIC INTERFERENCE IN ELECTRIC VEHI- CLE POWER SUPPLY SYSTEM

Electromagnetic interference (EMI) of the power supply system in electric vehicles will seriously affect the safety of the vehicle and passengers’ health. So a model of power supply system is presented to analyze its conducted EMI in the paper. This model shows the effects of paralleled interleaving DC/DC converter, which contains the new circular current EMI characteristics. Also, a novel power battery model is established considering both the energy dynamic processes and the high frequency features. Firstly, the power electronics devices are studied as the most important part of the DC/DC converter. Then, the equivalent model of the paralleled interleaving DC/DC converter is set up to express the interference source features. Also, the power battery, which is the main energy storage equipment in electric vehicles, is modeled as EMI propagation paths. Furthermore, loads of the power supply system, such as lead acid battery and low voltage devices, are investigated to evaluate their immunity. Finally, the system model is established. The system EMI is analyzed to get their generating causes, time domain and frequency domain characteristics based on both simulations and experiments.

This paper describes the challenges that have to be tackled when playing a game of tic-tactoe with the NAO humanoid robot. The most important aspects of tic-tac-toe for a robot are solving the Inverse Kinematics problem, and analyzing the game board using image processing. It succeeded in drawing om the board using the FABRIK algorithm for moving the arm, and Hough line and circle transform for recognizing the board and the symbols.
Stable isotope and scat analyses indicate diet and habitat partitioning in northern fur seals Callorhinus ursinus across the eastern Pacific

We used stable isotope (SI) and scat analyses to describe and compare the foraging eco- logy of northern fur seals Callorhinus ursinus from different rookeries throughout their North Amer- ican range, including rookeries on the following islands: Bogoslof Island (BI), Alaska; Reef and Vos- tochni on St. Paul Island (SPI), Alaska; and San Miguel Island (SMI), California. SI samples were collected from 36 adult females and 37 juveniles in Alaska, and 9 adult females and 7 pups on SMI during fall 2006. Isotopic analyses of blood and fur indicated differences in stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope values within an individual, between age classes, and among locations. At all sites, adult females generally had higher δ 13 C compared to their younger conspecifics for all tissues, suggesting that they forage in different locations. Mean δ 15 N values of adult females were lower com- pared to those of pups at SMI, higher than those of juveniles on SPI, and similar to those of juveniles on BI, suggesting differences in trophic level between age classes at all locations except on BI. We found differences in δ 13 C values at all islands, suggesting that animals at each location forage in dif- ferent oceanic domains. The δ 15 N values of all age classes indicated that animals at SMI and Vos- tochni feed at similar trophic levels within their respective communities, but feed at higher trophic levels than animals at Reef and BI. Scat analysis supported SI results in that animals from each loca- tion were found to feed on species associated with unique oceanic features. By using scat and SI analyses, we were able to acquire a better understanding of the foraging ecology of different-aged conspecifics from multiple locations.
Phylogeography of the Taiwanese Endemic Hillstream Loaches, Hemimyzon formosanus and H. taitungensis (Cypriniformes: Balitoridae)

Variations in nucleotide sequences within the mitochondrial control region were used to determine the paleogeography of speciation and diversification of 2 balitorids endemic to Taiwan. Examination of 11 populations of Hemimyzon formosanus and 5 populations of H. taitungensis respectively revealed 23 and 11 haplotypes within the mitochondrial control regions. Utilizing the neighbor-joining method and maximum-parsimony trees, we showed the presence of 3 groups and 2 subgroups in H. formosanus, and 1 group in H. taitungensis. The nested clade analysis, a method with a higher resolution, revealed that the 1 group of H. taitungensis could be further divided into 2 subgroups on the minimum spanning network. The nested clade analysis predicted the evolutionary divergence of populations in H. formosanus due to past fragmentation; furthermore, dispersion among populations of H. taitungensis was caused by long-distance colonization. The moderate gene flow and low genetic divergence within the mitochondrial control region suggest that local range expansion and recent colonization occurred in H. formosanus in west-central Taiwan and in H. taitungensis in eastern Taiwan. Our study showed that one of the major influences on the speciation of both western H. formosanus and eastern H. taitungensis was the Central Mountain Range of Taiwan. Moreover, deep genetic divergence and morphological differences suggest new phylogenetic species exist within H. formosanus.
The control of the frequency of the sub-terahertz source on the semiconductor superlattices for biophysical applications with use the change of the doping density

In the paper we study the possibility to control the frequency of the sub-THz source, based on the semiconductor superlattice by means of optimal spatial distribution of the doping density. We propose the appropriate mathematical model, which allows to describe the collective transport of charge in miniband semiconductor, where the spatial profile of the equilibrium charge density is defined by function. As the example we consider the uniform spatial distribution of doping density, contained local inhomogeneity, caused by local increase of density and described approximately by Gaussian function. We show that such inhomogeneity being placed in different areas of the transport region can affect the dynamics of charge domain, which, in turn, leads to increase (or decrease) of the frequency of current oscillations.
Determination of fracture toughness for small-sized specimens with ultrafine grain structure

The results of changing the fracture toughness of materials are given for the VT6 titanium alloy. Its coarse grain structure was reduced down to ultrafine structure by forging. The specific energy of fracture γ for the small-sized chevron-notched specimens was found thanks to the new technique. It is shown that severe plastic deformation reduces γ at room temperature. The structure of the surface fracture of the VT6 alloy’s ultrafine grain structure can be conceived as local zones of strong deformed material with a high concentration of pores. Such kind of structure cannot be formed only by means of crystallographic shears along close-packed planes. That fact proves the cardinal role of rotational modes of deformation in the origination and formation of a crack at various scale levels.
The Interrelationships of the Gastrotricha Using Nuclear Small rRNA Subunit Sequence Data, with an Interpretation Based on Morphology

Abstract Gastrotrichs are meiobenthic invertebrates of obscure origin and unclear phylogenetic alliances. Uncertainties also plague the intra-group relationship with major contrasts between the evolutionary scenarios inferred from morphology or molecules. In this study we analysed partial sequences of the 18S rDNA gene of 18 taxa (14 new and 4 published) to test morphological estimates of gastrotrich phylogeny and to verify whether controversial interrelationships from previous molecular data are due to poor sampling. Data were analysed using both maximum parsimony and maximum likelihood. MP topology was then forced to reflect published morphological estimates and the most parsimonious solutions from each constraint analysis was statistically compared against the unconstrained solution. MP analysis yielded a single tree with few nodes well supported by bootstrap resampling. These included the monophyly of the Chaetonotidae and the internal relationships of the members of this family, with Aspidiophorus appearing as the most basal member. The monophyly of the Turbanellidae was also well supported with some suggestion that its sister group might be Mesodasys . Lepidodasyidae was found to be an unnatural taxon with Lepidodasys forming a separated clade but unrelated also to the Thaumastodermatidae. With the exception of genera Lepidodasys and Neodasys , the Macrodasyida appeared to be resolved separately from the Chaetonotida, and Dactylopodola was resolved as the most basal macrodasyid. ML analysis yielded a tree not too dissimilar from MP, although Dactylopodola and Xenodasys were resolved as a clade. Statistics indicate that the output from our MP analysis is compatible with the classical view placing representatives of the two orders within two distinct evolutionary lines. Most of the constrained solutions, except the shortest, corroborate the monophyly of the two orders, whereas all five constrained solutions support also the notion that sees Neodasys as an early divergent clade along the Chaetonotida branch. Thus, results are generally compatible with the hypothesised evolutionary scenario based on morphological data, but are in contrast with previous findings from molecules. Future research should consider using the complete SSU rDNA gene sequence in their analysis and additional genes for deeper resolution.
Video Depth-From-Defocus — Supplemental Material

The input to our video depth-from-defocus approach is a radiometrically linearized video with temporally changing focus distances containing one or more focus ramps, but with otherwise constant camera settings. We assume that we know camera properties such as the focal length, aperture f -number, sensor size, as well as temporally sparse readings of the camera’s focus distances for some video frames.
Communication-limited stabilization of linear systems

This paper investigates the problem of stabilizing a linear, discrete-time plant using a digital link with a finite data rate. The plant model is infinite-dimensional and time-varying, with a real-valued output which is zero at negative times and distributed according to a probability density p at time zero. Finite and infinite horizon costs in terms of the m-th output moment are defined and the equations of the optimal, finite horizon coder-controller derived. Asymptotic quantization theory is then used to obtain the solution as the horizon tends to infinity, without needing to explicitly solve the finite horizon problem. It is shown that this limiting coder-controller is optimal with respect to the infinite horizon cost, provided that p satisfies certain technical conditions. This immediately leads to a necessary and sufficient condition for the existence of a coder-controller that takes the m-th output moment to zero asymptotically with time. If the open-loop plant is finite-dimensional and time-invariant, this condition simplifies to an inequality involving the data rate and the open-loop pole with greatest magnitude. Analogous results automatically hold for the related problem of state estimation with a finite data rate.
