description: This paper presents the influence of milling media on the structure and morphology of WC–Co powders for sintered tools. WC–Co powders have been milled in two different organic media, acetone and isohexane. The characterisation of the as-milled samples has been done by X-ray diffraction, scanning electron microscopy (SEM) and differential scanning calorimetry. The mean crystallite size decreases with milling time for the samples processed in acetone, while in the case of isohexane, the crystallite size stays at a relatively constant value when increasing the milling duration. The calculated mean crystallite size is below 50 nm for any milling duration, with larger values for acetone (16–46 nm) as compared to isohexane samples (10–12 nm). The SEM revealed that the dried powder is composed of agglomerated submicronic particles, and at high magnification, the presence of nanoparticles is noticed. The density of the aggregates was linked to the polarity of the solvents, which influences the sedimentation kinetics.

description: An increased use of models for measuring response styles is apparent in recent years with the multidimensional nominal response model (MNRM) as one prominent example. Inclusion of latent constructs representing extreme (ERS) or midpoint response style (MRS) often improves model fit according to information criteria. However, a test of absolute model fit is often not reported even though it could comprise an important piece of validity evidence. Limited information test statistics are candidates for this task, including the full (M2), ordinal (M2*), and mixed (C2) statistics, which differ in whether additional collapsing of univariate or bivariate contingency tables is conducted. Such collapsing makes sense when item categories are ordinal, which may not hold under the MNRM. More generally, limited information test statistics have gone unevaluated under nominal data and non-ordinal latent trait models. We present a simulation study evaluating the performance of M2, M2*, and C2 with the MNRM. Manipulated conditions included sample size, presence and type of response style, and strength of item slopes on substantive and style dimensions. We found that M2 sometimes had inflated Type I error rates, M2* always had little power, and C2 lacked power under some conditions. M2 and C2 may provide complementary and valuable information regarding model fit.

description: If there is one thing all university rankings have in common, it is that they are the target of widespread criticism. This article takes the many challenges university rankings are facing as its point of departure and asks how they navigate their hostile environment. The analysis proceeds in three steps. First, we unveil two modes of ranking critique, one drawing attention to negative effects, the other to methodological shortcomings. Second, we explore how rankers respond to these challenges, showing that they either deflect criticism with a variety of defensive responses or that they respond confidently by drawing attention to the strengths of university rankings. In the last step, we examine mutual engagements between rankers and critics that are based on the entwinement of methodological critique and confident responses. While the way rankers respond to criticism generally explains how rankings continue to flourish, it is precisely the ongoing conversation with critics that facilitates what we coin the discursive resilience of university rankings. The prevalence of university rankings is, in other words, a product of the mutual discursive work of their proponents and opponents.

description: Important ‘floral’ aromas naturally occur in grapes predominantly as flavourless glycoconjugate precursors. Since these aroma compounds can be released by hydrolysis, different glycosidase enzymes can potentially contribute different aromas to wines. In this paper, the effects of crude and purified Candida easanensis JK8 β-glucosidases on wine aroma precursors of Muscat of Alexandria grape powder were investigated by GC/MS combined with stir bar sorptive extraction (SBSE). A total of 19 bound volatile compounds were identified, including phenols, terpenes, aldehyde, ester and alcohols. The concentrations of terpenes especially nerol and geraniol, and β-Damascenone, a C13-norisoprenoid, contributes ﬂowery and slightly fruity aromas were signiﬁcantly increased in enzyme treated. These results suggest the potential application of this yeast β-glucosidase as an aroma-enhancing enzyme in winemaking.

description: We show how to expand the free energy of a matrix model coupled to arbitrary matter in powers of the matter coupling constant. Concentrating on $ν$ uncoupled Ising models---which have central charge $ν/2$---we work out the expansion to sixth order for $ν$ = 1, 2, and 3. Analyzing the series by the ratio method, we exhibit the spin-ordering phase transition. We discuss the limit $ν\rightarrow \infty$, which is especially clear in the low temperature expansion; we prove that in this limit the dependence of the model on $ν$ becomes trivial.

description: In dielectric breakdown, the phenomena of streamers formation and spontaneous branching is commonly observed. A deterministic negative streamer model is reviewed in this article. We recently have proposed that this reduced model is able to explain the branching phenomena, due to a Laplacian instability quite like in viscous fingering. Particular attention is paid to the physical interpretation of the model.

description: The effect of a magnetic field component parallel to the superconducting layers on longitudinal Josephson plasma oscillations in the layered high temperature superconductor Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ is shown to depend on the thermodynamic state of the underlying vortex lattice. Whereas the parallel magnetic field component depresses the Josephson Plasma Resonance (JPR) frequency in the vortex solid phase, it may enhance it in the vortex liquid. There is a close correlation between the behavior of microwave absorption near the JPR frequency and the effectiveness of pancake vortex pinning, with the enhancement of the plasma resonance frequency occurring in the absence of pinning, at high temperature close to the vortex melting line. An interpretation is proposed in terms of the attraction between pancake vortices and Josephson vortices, apparently also present in the vortex liquid state.

description: The method of Hawking to obtain black hole evaporation through Bogoljubov transformation between asymptotic modes (in and out) is generalized. The construction is local in that the in modes (of say positive frequency) are decomposed by Bogoljubov transformation into positive and negative frequency local inertial modes (i.e. those which are solutions of the d'Alembertian in terms of the local normal coordinates). From this follows an interesting reexpression of the local energy momentum tensor, more particularly of the outgoing energy flux. One finds that even in the local description there exists a partial thermal character parametrized by a local temperature. There exists quantum interference effects as well. These become negligible at large distance from the black hole.

description: Allosteric sites on proteins are targeted for designing more selective inhibitors of enzyme activity and to discover new functions. Acetylcholinesterase (AChE), which is most widely known for the hydrolysis of the neurotransmitter acetylcholine, has a peripheral allosteric subsite responsible for amyloidosis in Alzheimer’s disease through interaction with amyloid β-peptide. However, AChE plays other non-hydrolytic functions. Here, we identify and characterise using computational tools two new allosteric sites in AChE, which have allowed us to identify allosteric inhibitors by virtual screening guided by structure-based and fragment hotspot strategies. The identified compounds were also screened for in vitro inhibition of AChE and three were observed to be active. Further experimental (kinetic) and computational (molecular dynamics) studies have been performed to verify the allosteric activity. These new compounds may be valuable pharmacological tools in the study of non-cholinergic functions of AChE.

description: We propose a single phonon source based on nitrogen-vacancy (NV) centers, which are located in a diamond phononic crystal resonator. The strain in the lattice would induce the coupling between the NV centers and the phonon mode. The strong coupling between the excited state of the NV centers and the phonon is realized by adding an optical laser driving. This four level NV centers system exhibits the coherent population trapping (CPT), and yields giant resonantly enhanced acoustic nonlinearities, with zero linear susceptibility. Based on this nonlinearity, the single phonon source can be realized. We numerically calculate $g^{(2)}(0)$ of the single phonon source. We discuss the effects of the thermal noise and the external driving strength.

description: Redistribution of air masses due to atmospheric circulation causes loading deformation of the Earth's crust which can be as large as 20 mm for the vertical component and 3 mm for horizontal components. Rigorous computation of site displacements caused by pressure loading requires knowledge of the surface pressure field over the entire Earth surface. A procedure for computing 3-D displacements of geodetic sites of interest using a 6-hourly pressure field from the NCEP numerical weather models and the Ponte and Ray [2002] model of atmospheric tides is presented. We investigated possible error sources and found that the errors of our pressure loading time series are below the 15% level. We validated our model by estimating the admittance factors of the pressure loading time series using a dataset of 3.5 million VLBI observations from 1980 to 2002. The admittance factors averaged over all sites are 0.95 -+ 0.02 for the vertical displacement and 1.00 -+ 0.07 for the horizontal displacements. For the first time horizontal displacements caused by atmospheric pressure loading have been detected. The closeness of these admittance factors to unity allows us to conclude that on average our model quantitatively agrees with the observations within the error budget of the model. At the same time we found that the model is not accurate for several stations which are near a coast or in mountain regions. We conclude that our model is suitable for routine data reduction of space geodesy observations.

title: High-Strength Wastewater Treatment by Microalgae

Subjects: subject: Environmental Engineering
subject: FOS: Environmental engineering

description: Microalgae spontaneously convert CO2 and supplementary nutrients into biomass in the presence of light via photosynthesis, and at much higher rates than convention oil-producing crops. Algal biomass can then be transformed into methane via anaerobic bacteria-mediated fermentation, or to biodiesel via lipid extraction, as well as other byproducts of secondary metabolism. Production of biofuel by microalgae can be made more sustainable through coupling microalgal biomass production with existing power generation and wastewater treatment infrastructure. On the other hand, integration of algal biofuel production into wastewater treatment plant anaerobic digestion infrastructure has the potential to increase biogas production, decrease high and variable internal nitrogen loads, and improve sludge digestibility and dewaterability. The overall goals of this research were to investigate growth and nutrient uptake of two algal species, Spirulina platensis and Chlorella sp. in various growth conditions, while utilizing synthetic or real sludge centrate, or a mixture of centrate and nitrified effluent as a growth medium. Harvested algae were co-digested with wastewater activated sludge (WAS) at varying algae/WAS ratios and anaerobic digester performance was evaluated. Under batch conditions, two species of microalgae, Spirulina platensis and Chlorella sp., were grown on sludge centrate and a centrate/nitrified wastewater effluent mixture. Harvested algae were co-digested with waste activated sludge (WAS) at varying ratios. High growth (6.8 g m-2 d-1), nitrogen (36.5 g m-3 d-1 ) and phosphorous (6.5 g m-3 d-1 ) uptake rates were achieved with Chlorella on centrate. No growth was observed with S. platensis under the same conditions; however, both organisms grew well on the centrate/effluent mixture. Co-digestion of algae with WAS improved volatile solids reduction. Co-digestion with S. platensis improved biosolids dewaterability; however, Chlorella had a slight negative impact on dewaterability compared to WAS alone. Under continuous flow conditions, Spirulina platensis was cultivated in a benchscale airlift photobioreactor using synthetic wastewater (total nitrogen 412 mg/L, total phosphorous 90 mg/L, pH 9-10) with varying ammonia/total nitrogen ratios (50-100% ammonia with balance nitrate) and hydraulic residence times (15-25 d). High average biomass density (4,200 mg/L) and productivity (5.1 g m-2 d-1 ) were achieved when ammonia was maintained at 50% of the total nitrogen provided. Both high ammonia concentrations and mutual self-shading, which resulted from the high biomass density in the airlift reactor, were found to partially inhibit the growth of S. platensis. The performance of the airlift bioreactor used in this study compared favorably with other published studies.

description: There is no doubt that crime is one of the social phenomena that presents the greatest complexity when it comes to raising explanatory hypotheses about its etiology, the associated factors and the role played by each of the intervening part within the crime. In this area of knowledge, criminology has been one of the sciences that - historically - has dealt with the study of crime, the person of the offender, the victim and social control. For this reason, its inclusion within the academic training of police investigators has allowed the consolidation of an epistemological approach based on a comprehensive understanding of crime and its multifactorial nature. The following article presents a bibliographic review of the evolution of criminology and criminological knowledge, as well as the possible applications within criminal investigation, with their scope and limitations. The results confirm the relevance of criminology within the police function and, in particular, of forensic criminology in the investigation of crimes against people. The impact of knowledge generated from data science and its scope within epidemiological criminology in the intervention –preventive and investigative– of different criminal phenomena is discussed.

description: Acoustic quadrupole modes of sunlike stars vibrate when perturbed by a passing gravitational wave generated somewhere in the Universe. Here, we compute the imprint of the gravitational waves on the acoustic spectrum of these stars for gravitational events occurring near the supermassive black hole located at the center of the Milky Way. We found that in most cases the impact of gravitational waves in low-order quadrupole modes is not above the current observational threshold of detectability, although this should be in the reach of the next generation of near infrared observatories and asteroseismology satellite missions. Equally, we found that it is possible to follow the end phase of the coalescence of binaries with large chirp masses, as these phenomena have a unique imprint in the spectra of sunlike stars affecting sequentially several low-order quadrupole modes. Moreover, we discuss the different imprints on the acoustic spectra of the different types of binary systems constituted either by two white dwarfs, two neutron stars, two black holes or a compact star and a massive black hole.

description: Tyrosinase is known for an enzyme that plays a key role in producing the initial precursor of melanin biosynthesis. Inhibition of the catalytic reaction of this enzyme led to some advantage such as skin-whitening and anti-insect agents. To find a natural compound with inhibitory activity towards tyrosinase, the five flavonoids of kushenol A (1), 8-prenylkaempferol (2), kushenol C (3), formononetin (4) and 8-prenylnaringenin (5) were isolated by column chromatography from a 95% methanol extract of Sophora flavescens. The ability of these flavonoids to block the conversion of L-tyrosine to L-DOPA by tyrosinase was tested in vitro. Compounds 1 and 2 exhibited potent inhibitory activity, with IC50 values less than 10 µM. Furthermore, enzyme kinetics and molecular docking analysis revealed the formation of a binary encounter complex between compounds 1–4 and the enzyme. Also, all of the isolated compounds (1–5) were confirmed to possess antioxidant activity.

description: Chalcone represents an essential biosynthetic moiety due to its various pharmacological effects. The current study aimed to synthesize 17 chalcone derivatives (3a-q) by the direct reaction of substituted acetophenones and benzaldehyde via base-catalyzed Claisen-Schmidt condensation. All the synthesized compounds were characterized by IR, NMR, and mass spectrometry analyses. The synthesized compounds were then evaluated in vitro for their antibacterial, antifungal, and antileishmanial activities. Most of the chalcone derivatives exhibited good to excellent activities. Chalcone derivative (E)-1-(3-amino-4-bromophenyl)-3-(2,4,6-trimethoxyphenyl)prop-2-en-1-one (3q) showed the most potent antibacterial potential with its zone of inhibition values noted to be 33, 30, and 34 mm against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa respectively at 1000 μg/mL concentration. Compound 3q was also found to be the most potent against Leishmania major with the lowest IC50 value of 0.59±0.12 μg/mL as compared to the standard drug. Chalcone derivative (E)-3-(2,6-difluorophenyl)-1-(4-methoxyphenyl)prop-2-en-1-one (3i) was found to be the most potent antifungal agent with its zone of inhibition being 29 mm against Candida albican at a concentration of 500 μg/mL. In silico studies of 3i and 3q were performed to support the preliminary in vivo results. Structure-activity-relationship (SAR) study revealed that the presence of amino group and bromine on aromatic ring-A and methoxy groups on aromatic ring-B contributed to the enhanced biological activities of the chalcone derivatives. Overall, the study shows that 3i and 3q can be used as lead compounds for the discovery of novel antimicrobial agents. Nevertheless, current studies are preliminary, and further experimental studies and validation of the selected chalcones are needed to recommend their applicability.

description: In this paper we demonstrate how genetic algorithms can be used to reverse engineer an evaluation function's parameters for computer chess. Our results show that using an appropriate mentor, we can evolve a program that is on par with top tournament-playing chess programs, outperforming a two-time World Computer Chess Champion. This performance gain is achieved by evolving a program with a smaller number of parameters in its evaluation function to mimic the behavior of a superior mentor which uses a more extensive evaluation function. In principle, our mentor-assisted approach could be used in a wide range of problems for which appropriate mentors are available.

description: In the polarised Drell-Yan experiment at the COMPASS facility at CERN the beam of negatively-charged pions with 190 GeV/c momentum and intensity about $10^8$ pions/s interacted with transversely polarised NH$_3$ target. Muon pairs produced in Drell-Yan process (DY) were detected. Recently, the first ever Transverse Spin Asymmetries (TSAs) measurement in DY has been presented by COMPASS. A complementary analysis of the TSAs weighted by powers of the dimuon transverse momentum $q_T$ are presented. In the Transverse Momentum Dependent (TMD) PDF formalism, the $q_T$-weighted TSAs can be written in terms of products of the TMD PDFs of two colliding hadrons, unlike the conventional TSAs, which are their convolutions over quarks transverse momenta. The results are compared in a straightforward way with the weighted Sivers asymmetry in the SIDIS process, released by COMPASS in 2016.

description: The Cross Disciplinary Physics Unit (UFI) is a joint research Unit of the University of the Balearic Islands (UIB) and the Spanish National Research Council (CSIC) created in 2006 building upon the former Cross-Disciplinary Physics Department of IMEDEA (DFI-IMEDEA, Mediterranean Institute for Advance Studies) dating from 1995. The creation of the UFI is the first step in the implementation of the 2006-2009 CSIC´s Strategic Plan that in its Strategic Line RETICULA, and within the axis “Physics and Mathematics”, foresees the creation of a new joint research institute with the UIB on Cross-Disciplinary Physics and Complex Systems (IFISC). The programmatic goal is the development of interdisciplinary and strategic research from the established practices of physicists, acknowledging that important avenues of scientific development occur at the borders of established fields.
Pathway Model, Superstatistics, Tsallis Statistics, and a Generalized Measure of Entropy

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The pathway model of Mathai (2005) is shown to be inferable from the maximization of a certain generalized entropy measure. This entropy is a variant of the generalized entropy of order 'alpha', considered in Mathai and Rathie (1975), and it is also associated with Shannon, Boltzmann-Gibbs, Renyi, Tsallis, and Havrda-Charvat entropies. The generalized entropy measure introduced here is also shown to haveinteresting statistical properties and it can be given probabilistic interpretations in terms of inaccuracy measure, expected value, and information content in a scheme. Particular cases of the pathway model are shown to be Tsallis statistics (Tsallis, 1988) and superstatistics introduced by Beck and Cohen (2003). The pathway model's connection to fractional calculus is illustrated by considering a fractional reaction equation.

description: This study examined the term oplakvane in Bulgarian discourse. It refers to a communication practice – similar to complaining – and a range of associated cultural meanings for ways to construct a socio-economic and political reality. Data for this study included naturally occurring talk recorded during social events, interview responses from 50 participants, and a range of media postings from newspapers and online sources. These were examined through the lens of ethnography of communication and studies of terms for talk. By examining the term's context, potency, use, messages, meanings, and enactments, a larger cultural landscape is made available, illustrating how oplakvane not only describes negative talk, but references a communication ritual that serves to: (1) release the frustrations of everyday life, (2) celebrate and reinforce feelings of fate and despair, and (3) identify and locate a national Bulgarian character.
Photoacoustic Imaging using Combination of Eigenspace-Based Minimum Variance and Delay-Multiply-and-Sum Beamformers: Simulation Study

description: Delay and Sum (DAS), as the most common beamforming algorithm in Photoacoustic Imaging (PAI), having a simple implementation, results in a low-quality image. Delay Multiply and Sum (DMAS) was introduced to improve the quality of the reconstructed images using DAS. However, the resolution improvement is now well enough compared to high resolution adaptive reconstruction methods such as Eigenspace- Based Minimum Variance (EIBMV). We proposed to integrate the EIBMV inside the DMAS formula by replacing the existing DAS algebra inside the expansion of DMAS, called EIBMV-DMAS. It is shown that EIBMV-DMAS outperforms DMAS in the terms of levels of sidelobes and width of mainlobe significantly. For instance, at the depth of 35 mm, EIBMV-DMAS outperforms DMAS and EIBMV in the term of sidelobes for about 108 dB, 98 dB and 44 dB compared to DAS, DMAS, and EIBMV, respectively. The quantitative comparison has been conducted using Full-Width-Half-Maximum (FWHM) and Signal-to-Noise Ratio (SNR), and it was shown that EIBMV-DMAS reduces the FWHM about 1.65 mm and improves the SNR about 15 dB, compared to DMAS.

description: This paper demonstrates the use of genetic algorithms for evolving a grandmaster-level evaluation function for a chess program. This is achieved by combining supervised and unsupervised learning. In the supervised learning phase the organisms are evolved to mimic the behavior of human grandmasters, and in the unsupervised learning phase these evolved organisms are further improved upon by means of coevolution. While past attempts succeeded in creating a grandmaster-level program by mimicking the behavior of existing computer chess programs, this paper presents the first successful attempt at evolving a state-of-the-art evaluation function by learning only from databases of games played by humans. Our results demonstrate that the evolved program outperforms a two-time World Computer Chess Champion.

An Empirical Charge Transfer Potential with Correct Dissociation Limits

Subjects: subject: Chemical Physics (physics.chem-ph)

description: The empirical valence bond (EVB) method [J. Chem. Phys. 52, 1262 (1970)] has always embodied charge transfer processes. The mechanism of that behavior is examined here and recast for use as a new empirical potential energy surface for large-scale simulations. A two-state model is explored. The main features of the model are: (1) Explicit decomposition of the total system electron density is invoked; (2) The charge is defined through the density decomposition into constituent contributions; (3) The charge transfer behavior is controlled through the resonance energy matrix elements which cannot be ignored; and (4) A reference-state approach, similar in spirit to the EVB method, is used to define the resonance state energy contributions in terms of "knowable" quantities. With equal validity, the new potential energy can be expressed as a nonthermal ensemble average with a nonlinear but analytical charge dependence in the occupation number. Dissociation to neutral species for a gas-phase process is preserved. A variant of constrained search density functional theory is advocated as the preferred way to define an energy for a given charge.

Calculation of Dynamical and Many-Body Observables with the Polynomial Expansion Method for Spin-Fermion Models

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The calculation of two- and four-particle observables is addressed within the framework of the truncated polynomial expansion method (TPEM). The TPEM replaces the exact diagonalization of the one-electron sector in models for fermions coupled to classical fields such as those used in manganites and diluted magnetic semiconductors. The computational cost of the algorithm is O(N) -- with N the number of lattice sites -- for the TPEM which should be contrasted with the computational cost of the diagonalization technique that scales as O(N^4). By means of the TPEM, the density of states, spectral function and optical conductivity of a double-exchange model for manganites are calculated on large lattices and compared to previous results and experimental measurements. The ferromagnetic metal becomes an insulator by increasing the direct exchange coupling that competes with the double exchange mechanism. This metal-insulator transition is investigated in three dimensions.

description: This report presents the findings of a nationally representative study whose purpose was to explore the experiences, attitudes, and behaviours of New Zealand teens about digital communications including harm and/or distress. While there is growing interest in examining young people’s experiences and use of digital technologies, including the challenges and risks teens face, evidence based on representative data in the New Zealand context has been unavailable. The study focuses on the prevalence of New Zealand teens' experiences with a range of unwanted digital communications in the previous year and the impact these experiences had on them, both emotionally and in carrying out everyday life activities. It also describes teens’ responses, the effectiveness of their coping actions, and to whom they would turn for help in the future.
