Synthesis and conformational studies of 10, 10-dimethyltridecanolide
Creators: name: Hu, Thomas Qiuxiong
Publisher: name: University of British Columbia
Year: 2010

description: The synthesis of 10,10-dimethyltridecanolide (42) was achieved via a fifteen-step sequence in 9% overall yield. The hydrolysis of macrolides 42, 35, and ester 109 was used to probe the conformational behavior of macrolide 42. The results of this study were rationalized through molecular mechanics (MM2) calculations of conformations for macrolide 42. MM2 studies confirmed initial conformational analyses that macrolide 42 should exist predominantly in the [3434] conformation 42a. More importantly, they also revealed the existence of a [3344] conformation 42f. Hydrolysis studies showed that macrolides 42 and 35 hydrolyzed more slowly than ester 109 due to the steric effect of the intermediates. They also suggested that the minor conformation 42f very likely controlled the hydrolysis process of macrolide 42. [Formula Omitted]

description: The only source of ice formation in the Arctic during summer is a layer of ice called false-bottoms between an under-ice melt pond and the underlying ocean. Of interest is to give a mathematical model in order to determine the simultaneous growth and ablation of false-bottoms, which is governed by both of heat fluxes and salt fluxes. In one dimension, this problem may be considered mathematically as a two-phase Stefan problem with two free boundaries. Our main result is to prove the existence and uniqueness of the solution from the initial condition.

description: With the advances of data-driven machine learning research, a wide variety of prediction problems have been tackled. It has become critical to explore how machine learning and specifically deep learning methods can be exploited to analyse healthcare data. A major limitation of existing methods has been the focus on grid-like data; however, the structure of physiological recordings are often irregular and unordered which makes it difficult to conceptualise them as a matrix. As such, graph neural networks have attracted significant attention by exploiting implicit information that resides in a biological system, with interactive nodes connected by edges whose weights can be either temporal associations or anatomical junctions. In this survey, we thoroughly review the different types of graph architectures and their applications in healthcare. We provide an overview of these methods in a systematic manner, organized by their domain of application including functional connectivity, anatomical structure and electrical-based analysis. We also outline the limitations of existing techniques and discuss potential directions for future research.
Bias-free model fitting of correlated data in interferometry

description: In optical and infrared long-baseline interferometry, data often display significant correlated errors because of uncertain multiplicative factors such as the instrumental transfer function or the pixel-to-visibility matrix. In the context of model fitting, this situation often leads to a significant bias in the model parameters. In the most severe cases this can can result in a fit lying outside of the range of measurement values. This is known in nuclear physics as Peelle's Pertinent Puzzle. I show how this arises in the context of interferometry and determine that the relative bias is of the order of the square root of the correlated component of the relative uncertainty times the number of measurements. It impacts preferentially large data sets, such as those obtained in medium to high spectral resolution. I then give a conceptually simple and computationally cheap way to avoid the issue: model the data without covariances, estimate the covariance matrix by error propagation using the modelled data instead of the actual data, and perform the model fitting using the covariance matrix. I also show that a more imprecise but also unbiased result can be obtained from ignoring correlations in the model fitting.

description: Purpose: The development of metaheuristic algorithms has increased by researchers to use them extensively in the field of business, science, and engineering. One of the common metaheuristic optimization algorithms is called Grey Wolf Optimization (GWO). The algorithm works based on imitation of the wolves' searching and the process of attacking grey wolves. The main purpose of this paper to overcome the GWO problem which is trapping into local optima. Design or Methodology or Approach: In this paper, the K-means clustering algorithm is used to enhance the performance of the original Grey Wolf Optimization by dividing the population into different parts. The proposed algorithm is called K-means clustering Grey Wolf Optimization (KMGWO). Findings: Results illustrate the efficiency of KMGWO is superior to GWO. To evaluate the performance of the KMGWO, KMGWO applied to solve 10 CEC2019 benchmark test functions. Results prove that KMGWO is better compared to GWO. KMGWO is also compared to Cat Swarm Optimization (CSO), Whale Optimization Algorithm-Bat Algorithm (WOA-BAT), and WOA, so, KMGWO achieves the first rank in terms of performance. Statistical results proved that KMGWO achieved a higher significant value compared to the compared algorithms. Also, the KMGWO is used to solve a pressure vessel design problem and it has outperformed results. Originality/value: Results prove that KMGWO is superior to GWO. KMGWO is also compared to cat swarm optimization (CSO), whale optimization algorithm-bat algorithm (WOA-BAT), WOA, and GWO so KMGWO achieved the first rank in terms of performance. Also, the KMGWO is used to solve a classical engineering problem and it is superior

description: Considering the electron states inside and outside the solid, we derive a formula of photoemission intensity. A general theoretical way to determine electronic structures of solids from ARPES experiments is outlined. It is shown that the spectral function inside the solids cannot be measured directly by ARPES, the effects of free electron states on the electronic structure observed by ARPES measurements must be considered, and the results from ARPES experiments cannot be understood until these results have been made consistent with a theoretical calculation.

description: The Casimir force, which results from the confinement of the quantum mechanical zero-point fluctuations of the electromagnetic fields, has received significant attention in recent years for its effect on micro- and nano-scale mechanical systems. With few exceptions, experimental observations have been limited to conductive bodies interacting separated by vacuum or air. However, interesting phenomena including repulsive forces are expected to exist in certain circumstances between metals and dielectrics when the intervening medium is not vacuum. In order to better understand the effect of the Casimir force in such situations and to test the robustness of the generalized Casimir-Lifshitz theory, we have performed the first precision measurements of the Casimir force between two metals immersed in a fluid. For this situation, the measured force is attractive and is approximately 80% smaller than the force predicted by Casimir for ideal metals in vacuum. We present experimental results and find them to be consistent with Lifshitz's theory.

description: Electron neutrino has been the first neutral lepton to be foreseen and discovered last century. The un-ordered muon and its neutrino arose later by cosmic rays. The tau discover, the heaviest, the most unstable charged lepton, was found surprisingly on 1975. Its neutrino was hardly revealed just on 2000. So why High Energy Neutrino Astronomy should rise first via tau neutrino, the last, the most rare one? The reasons are based on a chain of three favorable coincidences found last decade: the neutrino masses and their flavor mixing, the UHECR opacity on Cosmic Black Body (GZK cut off on BBR), the amplified tau air-shower decaying in flight. Indeed guaranteed UHE GZK tau neutrinos, feed by muon mixing, while skimming the Earth might lead to boosted UHE tau, mostly horizontal ones. These UHE lepton decay in flight are spread, amplified, noise free Air-Shower: a huge event for an unique particle. To be observed soon: within Auger sky, in present decade. Its discover may sign of the first tau appearance.

description: Purpose: Recent studies suggest ultra-high dose rate (FLASH) irradiation can spare normal tissues from radiotoxicity, while efficiently controlling the tumor, and this is known as the FLASH effect. This study performed theoretical analyses about the impact of radiolytic oxygen depletion (ROD) on the cellular responses after FLASH irradiation. Methods: Monte Carlo simulation was used to model the ROD process, determine the DNA damage, and calculate the amount of oxygen depleted (LROD) during FLASH exposure. A mathematical model was applied to analyze oxygen tension (pO2) distribution in human tissues and the recovery of pO2 after FLASH irradiation. DNA damage and cell survival fractions (SFs) after FLASH irradiation were calculated. The impact of initial cellular pO2, FLASH pulse number, pulse interval, and radiation quality of the source particles on ROD and subsequent cellular responses were systematically evaluated. Results: The simulated electron LROD range was 0.38-0.43 μM/Gy when pO2 ranged from 7.5-160 mmHg. The calculated DNA damage and SFs show that radioprotective effect is only evident in cells with a lower pO2. Different irradiation setups alter the cellular responses by modifying the pO2. Single pulse delivery or multi-pulse delivery with pulse intervals shorter than 10-50 ms resulted in fewer DNA damages and higher SFs. Source particles with a low radiation quality have a higher capacity to deplete oxygen, and thus, lead to a more conspicuous radioprotective effect. Conclusions: The FLASH radioprotective effect due to ROD may only be observed in cells with a low pO2. Single pulse delivery or multi-pulse delivery with short pulse intervals are suggested for FLASH irradiation to avoid oxygen tension recovery during pulse intervals. Source particles with low radiation quality are preferred for their conspicuous radioprotective effects.

description: We consider the cosmology where some function f(G) of the Gauss-Bonnet term G is added to the gravitational action to account for the late-time accelerating expansion of the universe. The covariant and gauge invariant perturbation equations are derived with a method which could also be applied to general f(R,R^abR_ab,R^abcdR_abcd) gravitational theories. It is pointed out that, despite their fourth-order character, such f(G) gravity models generally cannot reproduce arbitrary background cosmic evolutions; for example, the standard LCDM paradigm with Omega_DE = 0.76 cannot be realized in f(G) gravity theories unless f is a true cosmological constant because it imposes exclusionary constraints on the form of f(G). We analyze the perturbation equations and find that, as in f(R) model, the stability of early-time perturbation growth puts some constraints on the functional form of f(G), in this case d^2 f/d G^2 < 0. Furthermore, the stability of small-scale perturbations also requires that f not deviate significantly from a constant. These analyses are illustrated by numerically propagating the perturbation equations with a specific model reproducing a representative LCDM cosmic history. Our results show how the f(G) models are highly constrained by cosmological data.

description: Objective: To compare non-contact acoustic micro-tapping optical coherence elastography (AuT-OCE) with destructive mechanical tests to confirm corneal elastic anisotropy. Design: Ex vivo, laboratory study with non-contact AuT-OCE followed by mechanical rheometry and extensometry. Subjects: Inflated cornea of whole-globe porcine eyes. Methods: A non-contact transducer was used to launch mechanical waves in the cornea that were imaged with phase-sensitive OCT at physiologically relevant pressures. Reconstruction of both Young's modulus (E) and out-of-plane shear modulus (G) in the cornea from experimental data was performed using a model of a nearly incompressible transversally isotropic (NITI) medium. Samples were then excised and parallel plate rheometry was performed to measure the shear modulus G. Corneal samples were then subjected to strip extensomety to measure the Young's modulus. Main Outcome Measures: Strong corneal anisotropy was confirmed with both AuT-OCE and mechanical tests, with the Young's and shear moduli differing by over an order of magnitude. These results show that AuT-OCE can quantify both moduli with a non-contact, non-invasive, clinically translatable technique.
Inszubordinált (függetlenedett) mellékmondatok a magyar  beszélt és írott beszélt nyelvben

description: Insubordination in spoken and in written spoken Hungarian


This study is the first attempt to examine insubordinate hogy (’that’)-clauses in spoken and written spoken Hungarian. Insubordination is the phenomenon when a clause has the formal features of subordinate clause but is used as independent, conventionalized main clause (for example: Hogy te milyen kényes vagy! ’How spoilt you are’). We found differences between the spoken and written spoken corpora in terms of insubordination, but we couldn’t find significant gender or age disparities. Hogy-insubordinations preferred to form collocations with discourse markers (tehát ’so’, hát ’well’, zóval ’so’) only in spoken genres, especially in conversations. The most frequent types of hogy-insubordinations had clear pragmatic, mostly metapragmatic functions: they expressed quotation, reformulation, added rhetoricity or emphasized speech acts like saying, questioning.

description: This article examines the causal link between foreign direct investment and economic growth in Mauritania during the period 1973-2019 using the ARDL (Autoregressive Distributed Lag model) method developed by Pesaran and Shin in 1998. The stationarity tests have put in highlights a cointegration of order 1 for the growth rate, the schooling rate, the trade openness rate, and the money supply. The empirical results of this study have shown that foreign direct investment, the exchange rate, and education rate have negatively significant effects on economic growth. On the other hand, the development of the financial system and trade openness have a significantly positive effect. As for domestic investment and inflation, they exert negative but statically insignificant effects.

Hateful Speech in Online College Communities

Publisher: name: Zenodo
Year: 2019

description: Background. Hateful speech bears negative repercussions and is particularly damaging in college communities. The efforts to regulate hateful speech on college campuses pose vexing socio-political problems, and the interventions to mitigate the effects require evaluating the pervasiveness of the phenomenon on campuses as well the impacts on students’ psychological state.

Data and Methods. Given the growing use of social media among college students, we target the above issues by studying the online aspect of hateful speech in a dataset of 6 million Reddit comments shared in 174 college communities. We devise a measure of College Hate Index (CHX) and examine its distribution in college subreddits across the categories of hateful speech, behavior, class, disability, ethnicity, gender, physical appearance, race, religion, and sexual orientation. We then employ a causal-inference framework to study the psychological effects of hateful speech in these college subreddits, particularly in the form of individuals’ online stress expression. Finally, we characterize their psychological endurance to hateful speech by analyzing their language– we examine their discriminatory keyword use with Sparse Additive Generative Model (SAGE), and their personality traits with Watson Personality Insights API.

Results. Our findings suggest that hateful speech is prevalent in college subreddits, and 25% of these subreddits show greater hateful speech than non-college subreddits. We further find that exposure to hate leads to greater stress expression. However, everybody exposed is not equally affected; some show lower psychological endurance than others. Low endurance individuals are more vulnerable to emotional outbursts, and are more neurotic than those with higher endurance to hate.

Discussion. Our work bears implications for policy-making and intervention efforts to tackle the damaging effects of online hateful speech in colleges. From technological perspective, our work caters to mental health support provisions on college campuses, and to moderation efforts in online college communities. In addition, given the charged aspect of speech dilemma, we highlight the ethical implications of ourwork. Ourwork lays the foundation for studying the psychological impacts of hateful speech in online communities in general, and situated communities in particular (the ones that have both an offline and an online analog).

A sub-threshold electric field applied on the emission side of the membrane enhances the number of electrons emitted by two orders of magnitude. This enhancement stems from field emitted electrons stimulated by the incident particles, which suggests that stacks of silicon membranes can form ultra-sensitive electron multipliers.

Studies of the adsorption of C₂H₄, CO and PH₃ on the (OOO1) surface of zirconium
Creators: name: Lau, Ji-Ren
Publisher: name: University of British Columbia
Year: 2010

description: The work in this thesis includes crystallographic investigations with low-energy electron diffraction (LEED) for two surface structures designated Zr(0001)-(1x1)-C (one of lower C coverage and the other of higher C coverage), as well as investigations of the adsorption of CO and PH₃ on the (0001) surface of zirconium by using Auger electron spectroscopy (AES) and LEED. For the lower-coverage Zr(0001)-(1x1)-C surface, the intensity-versus-energy (I(E)) curves for a set of diffracted beams were measured with a video LEED analyzer, and then compared with the results of multiple scattering calculations made for various structural models. Levels of correspondence between experimental and calculated I(E) curves were assessed with the reliability index proposed by Pendry, and surface geometries determined by the conditions for the best correspondence between experiment and calculation. The LEED intensity analysis suggests that under the lower C coverage, the C atoms in Zr(0001)-(1x1)-C appear to just occupy octahedral holes between the first and second layers of hep zirconium; this is similar to the situation reported by Wong et al for the N adsorption structure formed on Zr(0001). The LEED-determined Zr-C bond distance is 2.30 Å, which is in reasonable agreement with the value determined by X-ray crystallography for bulk ZrC (2.34 Å). Only a very preliminary analysis could be attempted for the higher-C-coverage Zr(0001)-(1x1)-C structure; there the C atoms may occupy all tetrahedral holes between the first and second layers of hep zirconium. Some I(E) curves were measured for CO adsorption on the Zr(0001) surface; a (2x2) LEED pattern formed with the initial CO exposure while a (1x1) pattern occurs with greater exposures. A comparison was made with CO adsorption on the Ti(0001) surface, and with oxygen adsorption on Zr(0001). The PH₃ adsorption on Zr(0001) can give a (3x3) LEED pattern which is unstable and only measurable in a short energy range. Unlike H₂S adsorption on Zr(0001) surface, ordering to form the (3x3)-PH₃ surface is inhibited by the loss of phosphorus during heating. An attempt was made to find the optimal recipe to get a sharp (3x3)-PH₃ pattern; it appears that the R[sub p] value (a ratio of Auger peak heights to indicate coverage) should be between 1.3 to 1.6, and that the ordering temperature should be higher than 560°C.

description: The temporal characteristics of motherese directed to 4 and 8 month-old children


Infant-directed speech (IDS) is typically characterized by slower speech rate compared to adult-directed speech (ADS). Whether final lengthening is disproportionally exaggerated in IDS vs. ADS relative to the global speech rate still remains a controversial issue. The present study aims to investigate the temporal characteristics of Hungarian infant-directed read speech. Results show that mothers spoke slower in IDS vs. ADS. The duration of the last three (the ultimate, the penultimate, and the antepenultimate) syllables in IDS vs. ADS differed significantly by being substantially longer. However, the duration ratios of the last, the last two or last three syllables compared to the rest of the utterance were independent of directedness (IDS vs. ADS).  Findings suggest that IDS is characterized by an overall lower articulation rate compared to ADS but, contrarily to some earlier findings, the final syllables did not extend disproportionally in IDS. Thus the boundary marking role of utterance-final syllables was not exaggerated by mothers addressing infants.

description: No abstracts are to be cited without prior reference to the author.The Working Group was unable to do a complete review of all these issues at its 1997 meeting. Nonetheless, it explored 5 topics associated with possible multispecies impacts on precautionary advice, biological reference points, and rebuilding strategies. The 5 topics included: * Algebraic and graphic extensions of the Sisserwine and Shepherd approach* Simulations of single species 'precautionary' analyses of two-species systems* Simulations of single species 'precautionary' analyses of a three-species system* Simulations of single species recovery strategies applied in a two species system* Graphical exploration of biological reference points in two-species systems with Lotka-Volterra predator-Prey interactions.

description: The supersymmetric SO(10) GUT based on the ${\bf{210\oplus 10\oplus 120\oplus 126\oplus {\bar {126}}}}$ Higgs system provides a minimal framework for the emergence of the R-parity exact MSSM at low energies and a viable supersymmetric seesaw explanation for the observed neutrino masses and mixing angles. We present formulae for MSSM decomposition of the superpotential invariants, tree level light charged fermion effective Yukawa couplings, Weinberg neutrino mass generation operator, and the $d=5,ΔB=ΔL \neq 0$ effective superpotential in terms of GUT parameters. We use them to determine fits of the 18 available fermion mass-mixing data in terms of the superpotential parameters of the NMSGUT and SUGRY(NUHM) type soft supersymmetry breaking parameters ($\{m_{\tilde f},m_{1/2},A_0,M^2_{H,\bar H}\} $) specified at the MSSM one loop unification scale $M_X^0=10^{16.33} $ GeV. Our fits are compatible with electroweak symmetry breaking and Unification constraints and yield right-handed neutrino masses in the leptogenesis relevant range : $10^8-10^{13} $ GeV. Matching the SM data requires lowering the strange and down quark Yukawas in the MSSM via large $\tanβ$ driven threshold corrections and characteristic soft Susy breaking spectra. The Susy spectra have light pure Bino LSP, heavy exotic Higgs(inos) and large $ μ,A_0,M_{H,\bar{H}}$ parameters $\sim 100$ TeV. Typically third generation sfermions are much \emph{heavier} than the first two generations. The smuon is often the lightest charged sfermion thus offering a Bino-CDM co-annihilation channel. The parameter sets obtained are used to calculate B violation rates which are found to be generically much faster($\sim 10^{-28}\, yr^{-1}$) than the current experimental limits. Improvements which may allow acceptable B violation rates are identified.

description: No abstracts are to be cited without prior reference to the author.Applying a cautious approach to fisheries management is sometimes difficult when your backs are to the wall! Thisproblem manifested itself in South Africa, political emancipation giving rise to expectations that can theoretically besatisfied only by short-term expedience in terms of allocated quotas. The history of the fisheries for rock lobster(really spiny lobster) in South Africa is outlined, with particular attention paid to whether or not the precautionaryprinciple has been and is being applied. Each fishery differs in management style. The biggest one, West Coast rocklobster, shows gradual mining out of stocks, but subsequent apparent stability having been upset by anomalies insuch crucial parameters as somatic growth rate. To sustain that fishery, hard choices had to be made betweenincreasing the risk of stock erosion and closure of the fishery. Fishermen's beliefs about the fishery were difficultto confound, and an inability to predict the.likely effects of naturally occurring phenomena made any implementationof the precautionary principle almost untenable to decision-makers. For each fishery, choices have had to be madebetween sustainability at current levels and rebuilding to stock sizes present only a decade ago. A consultativeapproach has been adopted, in which each side put forward their views on stock health in starting to developoperational management procedures, and regular review of the situation has become the norm. Caution is not seenas necessarily equating to reduction in quotas, although quotas have had to be reduced. The ecosystem effect isalso touched upon, specifical/y the interaction in some areas between West Coast rock lobster and the even morecommercially valuable abalone. Cautious fisheries management is considered crucial to South Africa's futurefisheries policies, but the challenge of getting it accepted surpasses natural science.

description: We present a two-color Kerr microscopy system based on two electronically synchronized erbium-fiber laser oscillators with independently tunable emission energies spanning most of the visible spectrum. Combining a spatial resolution below 2 $μ$m and sub-ps time resolution with high sensitivity and cryogenic sample temperatures, it is ideally suited for studying spin and valley dynamics in a wide range of two-dimensional materials. We illustrate its capabilities by studying a monolayer of the common semiconducting transition metal disulfide MoS$_2$.
Anomalous quantum reflection as a quasi-dynamical damping effect

description: We develop a quasi-analytical theory for the quantum reflection amplitude of Bose-Einstein condensates. We derive and calculate the decay-width of a Bose-Einstein condensate. A general relation between the time-dependent decay-law of the system and its quantum reflection amplitude allows us to explain the quantum reflection anomaly of Bose-Einstein condensates present in BEC-surface systems as a direct consequence of the repulsive particle interaction.

description: The temporal structure of read speech of male speakers of different ages


The purpose of the present study was to demonstrate if differences exist between Hungarian male speakers of different ages in (1) speech rate and (2) frequency and duration of pauses when their read speech is analysed. As expected, a strong correlation was found between age and the tempo values, however, the difference between the two tempo values, i.e. speech rate and articulation rate did not correlate with age. The number of pauses did not correlate with age and the durations of pauses between sentences did not vary by age either. It is concluded that the older speakers’ lower speech rate is a result of slower articulation and is not due to differences in the frequency or duration of pauses, however, it was also found that several speech parameters covered a wider range in older speakers, suggesting the existence of ’typical’ and ’atypical’ aged voices.

description: No abstracts are to be cited without prior reference to the author.Effective fisheries management requires considerable infonnation on life history characteristics,recruitment dynamics, habitat requirements, and fishery interactions for a given species. That wehave little ofthis infonnation for any ofthe myriad temperate reeffishes managed in the SouthAtlantic or Gulf ofMexico regions is clear, not only from our reliance on size limits, controlledeffort, or limited harvest, but on the repeated fail ures of all but complete closures of fisheries toallow recovery from overexploitation.
The Secular Evolution of a Close Ring-Satellite System: The Excitation of Spiral Bending Waves at a Nearby Gap Edge
Creators: name: Hahn, J. M.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: The secular perturbations exerted by an inclined satellite orbiting in a gap in a broad planetary ring tends to excite the inclinations of the nearby ring particles, and the ring's self-gravity can allow that disturbance to propagate away in the form of a spiral bending wave. The amplitude of this spiral bending wave is determined, as well as the wavelength, which shrinks as the waves propagate outwards due to the effects of the central planet's oblateness. The excitation of these bending waves also damps the satellite's inclination I. This secular I damping is also compared to the inclination excitation that is due to the satellite's many other vertical resonances in the ring, and the condition for inclination damping is determined. The secular I damping is likely responsible for confining the orbits of Saturn's two known gap-embedded moons, Pan and Daphnis, to the ring plane.

Evidence of a Broad Relativistic Iron Line from the Neutron Star Low-Mass X-ray Binary Serpens X-1

description: We report on an analysis of XMM-Newton data from the neutron star low mass X-ray binary (LMXB) Serpens X-1 (Ser X-1). Spectral analysis of EPIC PN data indicates that the previously known broad iron K$α$ emission line from this source has a significantly skewed structure with a moderately extended red wing. The asymmetric shape of the line is well described with the laor and diskline models in XSPEC and strongly supports an inner accretion disk origin of the line. To our knowledge this is the first strong evidence of a relativistic line in a neutron star LMXB. This finding suggests that the broad lines seen in other neutron star LMXBs likely originate from the inner disk as well. Detailed study of such lines opens up a new way to probe neutron star parameters and their strong gravitational fields. The red wing of the iron line from Ser X-1 is not as broad as that observed from some black hole systems. This is not unreasonable for a neutron star system, as the accretion disk has to terminate at or before the hard stellar surface. Finally, the inferred source inclination angle in the approximate range 40 degree to 60 degree is consistent with the lack of dips and eclipses from Ser X-1.

description: We report synthesis, structure/micro-structure, resistivity under magnetic field [R(T)H], Raman spectra, thermoelectric power S(T), thermal conductivity K(T), and magnetization of ambient pressure argon annealed polycrystalline bulk samples of MgB2, processed under identical conditions. The compound crystallizes in hexagonal structure with space group P6/mmm. Transmission electron microscopy (TEM) reveals electron micrographs showing various types of defect features along with the presence of 3-4nm thick amorphous layers forming the grain boundaries of otherwise crystalline MgB2. Raman spectra of the compound at room temperature exhibited characteristic phonon peak at 600 cm-1. Superconductivity is observed at 37.2K by magnetic susceptibility C(T), resistivity R(T), thermoelectric power S(T), and thermal conductivity K(T) measurements. The power law fitting of R(T) give rise to Debye temperature at 1400K which is found consistent with the theoretical fitting of S(T), exhibiting ThetaD of 1410K and carrier density of 3.81x 1028/m3. Thermal conductivity K(T) shows a jump at 38K, i.e., at Tc, which was missing in some earlier reports. Critical current density (Jc) of up to 105 A/cm2 in 1-2T (Tesla) fields at temperatures (T) of up to 10K is seen from magnetization measurements. The irreversibility field, defined as the field related to merging of M(H) loops is found to be 78, 68 and 42 kOe at 4, 10 and 20K respectively. The superconducting performance parameters viz. irreversibility field (Hirr) and critical current density Jc(H) of the studied MgB2 are improved profoundly with addition of nano-SiC and nano-Diamond. The physical property parameters measured for polycrystalline MgB2 are compared with earlier reports and a consolidated insight of various physical properties is presented.
