The Burst Mode of Protostellar Accretion

Year: 2006

subject: FOS: Physical sciences

description: We present new numerical simulations in the thin-disk approximation which characterize the burst mode of protostellar accretion. The burst mode begins upon the formation of a centrifugally balanced disk around a newly formed protostar. It is comprised of prolonged quiescent periods of low accretion rate (typically $\la 10^{-7} \Msun$ yr$^{-1}$) which are punctuated by intense bursts of accretion (typically $\ga 10^{-4} \Msun$ yr$^{-1}$, with duration $\la 100$ yr) during which most of the protostellar mass is accumulated. The accretion bursts are associated with the formation of dense protostellar/protoplanetary embryos, which are later driven onto the protostar by the gravitational torques that develop in the disk. Gravitational instability in the disk, driven by continuing infall from the envelope, is shown to be an effective means of transporting angular momentum outward, and mass inward to the protostar. We show that the disk mass always remains significantly less than the central protostar mass throughout this process. The burst phenomenon is robust enough to occur for a variety of initial values of rotation rate, frozen-in (supercritical) magnetic field, and density-temperature relations. Even in cases where the bursts are nearly entirely suppressed, a moderate increase in cloud size or rotation rate can lead to vigorous burst activity. We conclude that most (if not all) protostars undergo a burst mode of evolution during their early accretion history, as inferred empirically from observations of FU Orionis variables.

description: Background: There is a growing interest in nonpharmacological approaches for essential tremor (ET), including tremor cancelation devices. However, the true efficacy of such devices in ET remains unclear. Methods: A systematic literature review was conducted using standardized criteria regarding efficacy and comfortability. Devices focused on design or experimental testing in which tremor was simulated in a robot were excluded. Results: Out of 324 articles initially identified, 12 articles were included. Orthoses using biomechanical loading and neuromodulation with electrical stimulation, and external tremor cancelation devices, were the main interventions used to suppress tremor. All devices were designed to control tremor of the upper limbs at different anatomical locations. Overall, an average tremor attenuation of 50–98% was reported (level of evidence III). Interference with voluntary movements and portability was described as the main drawback. Discussion: In conclusion, this review highlights the growing interest in emerging tremor control devices and the importance of assessing comfort without affecting voluntary movements. However, the level of evidence regarding the efficacy of these tremor control devices remains low. An integrated multidisciplinary combination approach of engineering, robotics, physiology, physiotherapy, and clinical assessment is needed to improve the quality of non-pharmacological interventions for ET.

description: The compound 2,3-dehydrosilychristin, a flavonolignan linked to silychristin and silymarin, remains intriguing due to its challenging isolation from silymarin. While silymarin has been the exclusive source of flavonolignans – silybin, silychristin and silydianin − 2,3-dehydrosilychristin is reported in this study from Vitex negundo Linn. leaves. 2,3-Dehydrosilychristin (7) and 14 other compounds were isolated through focused extraction. Its subsequent pharmacological evaluation demonstrated potent antioxidant and in-vitro anti-inflammatory effects, notably inhibiting cytokines TNF-α, IL-6, IL-8 and VEGF. In in-vivo assessments, 2,3-dehydrosilychristin (7) revealed remarkable hepatoprotective potential by reducing liver enzyme levels AST and ALT. These findings expand the potential of 2,3-dehydrosilychristin and suggest bioprospecting Vitex species as alternate sources of bioactive flavonolignans.

Year: 2023

description: As a result of the studies of plant-parasitic nematodes of trees and shrubs on the territory of Donetsk Botanical Garden were recorded two species of Longidorus Micoletzky, 1922 (Dorylaimida: Longidoridae): L. elongatus (de Man, 1876) has previously been recorded in greenhouses of Donetsk Botanical Garden, L . leptocephalus Hooper, 1961 was registered for the first time for Donbass. Both species are polyphagous root ectoparasites. Longidorus elongatus was registered in rhizosphere of goat willow (Salix caprea L.), and L. leptocephalus – in rhizosphere of horse chestnut (Aesculus hippocastanum L.). The paper contains descriptions, morphological and morphometric characteristics of recorded populations, trophical associations, and brief data on the distribution, biology, ecology and harmfulness of the species. The morphometrics of the Donbass populations of both species generally are in agreement with literature data, but regional isolates has some differences.
A Self-Learning Disturbance Observer for Nonlinear Systems in Feedback-Error Learning Scheme

description: This paper represents a novel online self-learning disturbance observer (SLDO) by benefiting from the combination of a type-2 neuro-fuzzy structure (T2NFS), feedback-error learning scheme and sliding mode control (SMC) theory. The SLDO is developed within a framework of feedback-error learning scheme in which a conventional estimation law and a T2NFS work in parallel. In this scheme, the latter learns uncertainties and becomes the leading estimator whereas the former provides the learning error to the T2NFS for learning system dynamics. A learning algorithm established on SMC theory is derived for an interval type-2 fuzzy logic system. In addition to the stability of the learning algorithm, the stability of the SLDO and the stability of the overall system are proven in the presence of time-varying disturbances. Thanks to learning process by the T2NFS, the simulation results show that the SLDO is able to estimate time-varying disturbances precisely as distinct from the basic nonlinear disturbance observer (BNDO) so that the controller based on the SLDO ensures robust control performance for systems with time-varying uncertainties, and maintains nominal performance in the absence of uncertainties.

description: A series of new phosphorylated derivatives of thiazolidinedione was synthesized for the first time with high yields (92–96%) in short reaction time (7–15min) by the reaction of 4-{[(5E)-2,4-dioxo-1,3-thiazolidin-5-ylidene]methyl}phenyl ethyl phosphorochloridate with various heterocyclic amines by microwave irradiation technique under solvent-free condition. A study on in silico ADMET and molecular docking was performed for all the molecules to acquire an insight on drug likeliness behavior and also their ability to inhibit the enzyme, α-amylase. The molecules with momentous pharmacokinetic properties with substantial binding affinity were synthesized. The synthesized compounds were characterized spectroscopically to confirm their structure and then in vitro α-amylase inhibitory activity was also carried out for all the newly prepared compounds. The compounds 9b, 9e, 9f, and 9j reported the highest inhibition amongst the synthesized compounds. All the leftover compounds displayed modest to excellent inhibition in comparison with reference drug, Acarbose.

description: Quantum convolutional codes can be used to protect a sequence of qubits of arbitrary length against decoherence. We introduce two new families of quantum convolutional codes. Our construction is based on an algebraic method which allows to construct classical convolutional codes from block codes, in particular BCH codes. These codes have the property that they contain their Euclidean, respectively Hermitian, dual codes. Hence, they can be used to define quantum convolutional codes by the stabilizer code construction. We compute BCH-like bounds on the free distances which can be controlled as in the case of block codes, and establish that the codes have non-catastrophic encoders.

description: JUNO is a 20-kton liquid scintillator detector aiming to determine the neutrino mass ordering, precisely measure the oscillation parameters, detect the astrophysical neutrinos and search for exotic physics. It is designed to reach an energy resolution of 3% at 1 MeV with the highest ever PMT coverage, using two types of 20 inch phototubes: MCP-PMT from NNVT and dynode-PMT from Hamamatsu. In this article, the gain and charge response of the MCP and dynode PMTs are investigated with the study of JUNO Central Detector prototype. The linearity of the MCP-PMT charge output is measured too to check the effect of a long tail on its charge spectrum.
Phonological vowel disorders : a case study
Creators: name: Pegg, Lauren Jane
Publisher: name: University of British Columbia
Year: 2010

description: The purposes of the present study were: 1) to provide descriptions, both phonological and acoustic, of the vowel system of a child who exhibited a phonological disturbance in his vowel system, and 2) to examine the effects that intervention targeting consonants would have on his vowel system. No specific hypotheses were proposed, although it was implied that there would be some effect. The subject, S, was one of six subjects in a doctoral research study investigating the application of non-linear phonological theory to the assessment and remediation of developmental phonological disorders. The data were selected from the initial assessment session and a reassessment after two blocks of intervention. Both phonological and acoustic analyses of the data were performed. Acoustic measurements included the fundamental frequency and the frequencies of the first and second formants for each phone. The data showed that S had a large phonetic inventory of vowels with a high proportion of vowel errors. Phonemes exhibited considerable variability but one primary phone could usually be identified. Significant in the phonological description were the following: 1) a high front vowel, a back rounded vowel, a low vowel, and a central vowel were among those most accurately produced by S, 2) there were a significant number of errors in the non-high, unrounded phonemes, and 3) /u/ exhibited a high proportion of errors. In general, errors were not sensitive to consonantal context. Acoustically, while the formant patterns for each phone differed from the others, S's vowels were found to be different in some ways from normal. Specifically, the frequency of F2 for his back vowels is higher than expected and the frequency of Fl for /a/ is lower than expected. In addition to some differences in formant frequency, the acoustic data on S's vowels show much more variability than normal. Changes in the data occurred, both phonologically and acoustically, between the pre-and post-treatment assessment Changes included: 1) improvement in the accurate production of /u/, 2) shifts in the phonetic representation of non-high, unrounded vowels, 3) a decrease in random phonemic error, 4) a decrease in the second formant frequency of back vowels and an increase in first formant frequency of /a/, 5) a decrease in variability of both first and second formant frequency, and 6) a decrease in fundamental frequency. While it was possible to describe differences between the pre- and post-treatment data, it was not possible to ascribe these changes solely to intervention. It is difficult to know whether intervention had a direct effect on vowel production or whether the changes which occurred were more general effects of intervention or simply natural events, coincidental with the intervention program.

description: The metal oxide polymeric methyltrioxorhenium [(CH3)xReO3] is an unique epresentative of a layered inherent conducting organometallic polymer which adopts the structural motifs of classical perovskites in two dimensions (2D) in form of methyl-deficient, corner-sharing ReO5(CH3) octahedra. In order to improve the characteristics of polymeric methyltrioxorhenium with respect to its physical properties and potential usage as an inherentconducting polymer we tried to optimise the synthetic routes of polymeric modifications of 1 to obtain a sintered ceramic material, denoted ceramic MTO. Ceramic MTO formed in a solvent-free synthesis via auto-polymerisation and subsequent sintering processing displays clearly different mechanical and physical properties from polymeric MTO synthesised in aqueous solution. Ceramic MTO is shown to display activated Re-C and Re=O bonds relative to MTO. These electronic and structural characteristics of ceramic MTO are also reflected by a different chemical reactivity compared with its monomeric parent compound. First examples of the unprecedented reactivity of ceramic MTO in the field of amine oxidations are shown - results which warrant further exploitation.

description: We report the specific heat measurements on the newly discovered Fe-based layered superconductor LaO_0.9F_{0.1-delta}FeAs with the onset transition temperature T_c \approx 28 K. A nonlinear magnetic field dependence of the electronic specific heat coefficient gamma(H) has been found in the low temperature limit, which is consistent with the prediction for a nodal superconductor. The maximum gap value Delta_0 \approx 3.4$\pm$0.5 meV was derived by analyzing gamma(H) based on the d-wave model. We also detected the electronic specific heat difference between 9 T and 0 T in wide temperature region, a specific heat anomaly can be clearly observed near T_c. The Debye temperature of our sample was determined to be about 315.7 K. Our results suggest an unconventional mechanism for this new superconductor.

description: The impact of stellar rotation on the morphology of star cluster colour-magnitude diagrams is widely acknowledged. However, the physics driving the distribution of the equatorial rotation velocities of main-sequence turn-off (MSTO) stars is as yet poorly understood. Using Gaia Data Release 2 photometry and new Southern African Large Telescope medium-resolution spectroscopy, we analyse the intermediate-age ($\sim1\,$Gyr-old) Galactic open clusters NGC 3960, NGC 6134 and IC 4756 and develop a novel method to derive their stellar rotation distributions based on SYCLIST stellar rotation models. Combined with literature data for the open clusters NGC 5822 and NGC 2818, we find a tight correlation between the number ratio of slow rotators and the clusters' binary fractions. The blue-main-sequence stars in at least two of our clusters are more centrally concentrated than their red-main-sequence counterparts. The origin of the equatorial stellar rotation distribution and its evolution remains as yet unidentified. However, the observed correlation in our open cluster sample suggests a binary-driven formation mechanism.

description: We consider the wave equation (-\dt^2+\dr^2 -V -V_L(-Δ_{S^2})) u = fF'(|u| ^2) u with (t,ρ,θ,ϕ) in R x R x S^2. The wave equation on a spherically symmetric manifold with a single closed geodesic surface or on the exterior of the Schwarzschild manifold can be reduced to this form. Using a smoothed Morawetz estimate which does not require a spherical harmonic decomposition, we show that there is decay in L^2_{loc} for initial data in the energy class, even if the initial data is large. This requires certain conditions on the potentials V, V_L, and f. We show that a key condition on the weight in the smoothed Morawetz estimate can be reduced to an ODE condition, which is verified numerically.

Publisher: name: Zenodo
Year: 2019

description: This paper revisits replication coupled with checkpointing for fail-stop errors. Replication enables the application to survive many fail-stop errors, thereby allowing for longer checkpointing periods. Previously published works use replication
 with the \norestart strategy, which works as follows: (i) compute the application Mean Time To Interruption (MTTI) \MM as a function of the number of processor pairs and the individual processor Mean Time Between Failures (MTBF); (ii) use
 checkpointing period $\pdalyrep = \sqrt{2 \MM \CC}$ à la Young/Daly, where $\CC$ is the checkpoint duration; and (iii) never restart failed processors until the application crashes. We introduce the \restart strategy where failed processors are restarted after each checkpoint, which may introduce additional overhead during checkpoints but prevents the application configuration from degrading throughout successive checkpointing periods. We show how to compute the optimal checkpointing period \popt for this \restart strategy and prove that its length is an order of magnitude higher than
 \pdalyrep.We show through simulations that using \popt and the \restart strategy, instead of \pdalyrep and the usual \norestart strategy, significantly decreases the overhead induced by replication.

Swim bladder stress syndrome in arctic charr (salvelinus alpinus)
Creators: name: Ricks, William Remmert
Publisher: name: University of British Columbia
Year: 2010

description: I investigated the condition known as Swim Bladder Stress Syndrome (SBSS) in a Nauyuk Lake, Northwest Territories strain of Arctic charr (Salvelinus alpinus). Induction of the condition was attempted through an extended period of acute sessions of applied handling stress. Water quality was controlled throughout the entire 5 month project. Blood analyses were performed (packed cell volume, plasma Cortisol and glucose) to confirm that the fish had been physiologically stressed. In addition, bacteriology, virology, histopathology and a tissue homogenate injection trial were performed in an attempt to ascertain the exact etiology of this condition. The charr were subjected to two stress treatments (stressed and non-stressed), both treatments occurring at each of two density levels (75 kg/m³ and 150 kg/m³). The incidence of SBSS in the treatment groups was not statistically significant (Log-likelihood ratio; P > 0.05), although seven out of a total of eight (87.5%) cases were fish from high density groups. Cortisol levels were higher in the low density groups as opposed to the high density groups for all three samplings, significantly so at the third sampling. Bacteriology, virology, histopathology and the tissue homogenate injection trial all failed to demonstrate any source of the condition. It is questionable whether Swim Bladder Stress Syndrome in Arctic charr is in fact due to stress as previously indicated in the scientific literature.

Existing methods for solving this problem can be described as search procedures for an invariant whose quantification prefix fits a particular template. We propose an alternative constructive approach that does not prescribe, a priori, a specific quantifier prefix. Instead, the required prefix is automatically inferred without any search by carefully analyzing the structural symmetries of the protocol. The key insight underlying this approach is that symmetry and quantification are closely related concepts that express protocol invariance under different re-arrangements of its components. We propose symmetric incremental induction, an extension of the finite-domain IC3/PDR algorithm, that automatically derives the required quantified inductive invariant by exploiting the connection between symmetry and quantification. While various attempts have been made to exploit symmetry in verification applications, to our knowledge, this is the first demonstration of a direct link between symmetry and quantification in the context of clause learning during incremental induction. We also describe a procedure to automatically find a minimal finite size, the cutoff, that yields a quantified invariant proving safety for any size. Our approach is implemented in IC3PO, a new verifier for distributed protocols that significantly outperforms the state-of-the-art, scales orders of magnitude faster, and robustly derives compact inductive invariants fully automatically.

description: The photoelectron circular dichroism (PECD) of the O 1s-photoelectrons of trifluoromethyloxirane(TFMOx) is studied experimentally and theoretically for different photoelectron kinetic energies. The experiments were performed employing circularly polarized synchrotron radiation and coincidentelectron and fragment ion detection using Cold Target Recoil Ion Momentum Spectroscopy. The corresponding calculations were performed by means of the Single Center method within the relaxed-core Hartree-Fock approximation. We concentrate on the energy dependence of the differential PECD of uniaxially oriented TFMOx molecules, which is accessible through the employed coincident detection. We also compare results for differential PECD of TFMOx to those obtained for the equivalent fragmentation channel and similar photoelectron kinetic energy of methyloxirane (MOx), studied in our previous work. Thereby, we investigate the influence of the substitution of the methyl-group by the trifluoromethyl-group at the chiral center on the molecular chiral response. Finally, the presently obtained angular distribution parameters are compared to those available in literature.

description: The Naming Game is a model of non-equilibrium dynamics for the self-organized emergence of a linguistic convention or a communication system in a population of agents with pairwise local interactions. We present an extensive study of its dynamics on complex networks, that can be considered as the most natural topological embedding for agents involved in language games and opinion dynamics. Except for some community structured networks on which metastable phases can be observed, agents playing the Naming Game always manage to reach a global consensus. This convergence is obtained after a time generically scaling with the population's size $N$ as $t\_{conv} \sim N^{1.4 \pm 0.1}$, i.e. much faster than for agents embedded on regular lattices. Moreover, the memory capacity required by the system scales only linearly with its size. Particular attention is given to heterogenous networks, in which the dynamical activity pattern of a node depends on its degree. High degree nodes have a fundamental role, but require larger memory capacity. They govern the dynamics acting as spreaders of (linguistic) conventions. The effects of other properties, such as the average degree and the clustering, are also discussed.

Slow Orthostatic Tremor: Review of the Current Evidence
Creators: name: Hassan, Anhar
name: Caviness, John
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2019

description: Background: Orthostatic tremor (OT) is defined as tremor in the legs and trunk evoked during standing. While the classical description is tremor of ≥13 Hz, slower frequencies are recognized. There is disagreement as to whether the latter represents a slow variant of classical OT, or different tremor disorder(s) given frequent coexistent neurological disease. Methods: A systematic literature search of PubMed was performed in February 2019 for “slow orthostatic tremor” and related terms which generated 573 abstracts, of which 61 were included. Results: Between 1970 and 2019, there were 70 cases of electrophysiologically confirmed slow OT. Two-thirds were female, of mean age 60 years (range 26–86), and mean disease duration 6 years (range 0–32). One-third of cases were isolated, and two-thirds had a coexistent disorder(s), including parkinsonism (30%), ataxia (12%), and dystonia (10%). Postural arm tremor was present in 34%. Median tremor frequency was 6–7 Hz (range 3–12). Tremor bursts ranged from 50 to 150 ms duration, and were alternating or synchronous in antagonistic and/or analogous muscles. Low and high coherences were reported. Five cases (7%) had coexistent classical OT. Clonazepam was the most effective medication across all frequencies, and levodopa was effective for 4–7 Hz OT with coexistent parkinsonism. Two cases resolved with the treatment of Graves’ disease. Electrophysiology and imaging predominantly support a central tremor generator. Discussion: While multiple lines of evidence separate slow OT from classical OT, clinical and electrophysiological overlap may occur. Primary and secondary causes are identified, similar to classical OT. Further exploration to clarify these slow OT subtypes, clinically and neurophysiologically, is proposed.

description: The paper presents a solution for the problem of choosing a method for analytical determining of weight factors for a genetic algorithm additive fitness function. This algorithm is the basis for an evolutionary process, which forms a stable and effective query population in a search engine to obtain highly relevant results. The paper gives a formal description of an algorithm fitness function, which is a weighted sum of three heterogeneous criteria. The selected methods for analytical determining of weight factors are described in detail. It is noted that expert assessment methods are impossible to use. The authors present a research methodology using the experimental results from earlier in the discussed project "Data Warehouse Support on the Base Intellectual Web Crawler and Evolutionary Model for Target Information Selection". There is a description of an initial dataset with data ranges for calculating weights. The calculation order is illustrated by examples. The research results in graphical form demonstrate the fitness function behavior during the genetic algorithm operation using various weighting options.

Tremor Other Hyperkinet Mov. 2019; 9. doi: 10.7916/tohm.v0.721 In this issue of the journal, Hassan and Caviness reviewed the controversial topic of slow orthostatic tremor (OT). Based on their review of the relevant literature, Hassan and Caviness concluded that “multiple lines of evidence separate slow OT from classical OT,” but they also noted that “clinical and electrophysiologic overlap may occur.” We were invited to discuss the significance of this overlap within the context of tremor classification.

Sharing quantum nonlocality and genuine nonlocality with independent observables

description: Recently the authors in [Phys. Rev. Lett. 125, 090401 (2020)] considered the following scenario: Alice and Bob each have half of a pair of entangled qubit state. Bob measures his half and then passes his part to a second Bob who measures again and so on. The goal is to maximize the number of Bobs that can have an expected violation of the Clauser-Horne-Shimony-Holt (CHSH) inequality with the single Alice. By taking the maximally entangled pure two-qubit state as an example, it has been constructively proved that arbitrarily many independent Bobs can share the nonlocality with the single Alice. Here we demonstrate that arbitrarily many independent observers can share the nonlocality of a single arbitrary dimensional bipartite entangled but not necessary two-qubit entangled state. Further, taking the generalized GHZ states as an example, we show that at most two Charlies can share the genuine nonlocality of a single generalized GHZ state with an Alice and a Bob.

description: We investigate the dynamics of information in isolated multi-qubit systems. It is shown that information is in not only local form but also nonlocal form. We apply a measure of local information based on fidelity, and demonstrate that nonlocal information can be directly related to some appropriate well defined entanglement measures. Under general unitary transformations, local and nonlocal information will exhibit unambiguous complementary behavior with the total information conserved.

description: A series of new phosphorylated derivatives of thiazolidinedione was synthesized for the first time with high yields (92–96%) in short reaction time (7–15min) by the reaction of 4-{[(5E)-2,4-dioxo-1,3-thiazolidin-5-ylidene]methyl}phenyl ethyl phosphorochloridate with various heterocyclic amines by microwave irradiation technique under solvent-free condition. A study on in silico ADMET and molecular docking was performed for all the molecules to acquire an insight on drug likeliness behavior and also their ability to inhibit the enzyme, α-amylase. The molecules with momentous pharmacokinetic properties with substantial binding affinity were synthesized. The synthesized compounds were characterized spectroscopically to confirm their structure and then in vitro α-amylase inhibitory activity was also carried out for all the newly prepared compounds. The compounds 9b, 9e, 9f, and 9j reported the highest inhibition amongst the synthesized compounds. All the leftover compounds displayed modest to excellent inhibition in comparison with reference drug, Acarbose.
