description: We study the thermal effects on the nuclear matter (NM) properties such as binding energy, incompressibility, free symmetry energy and its coefficients using NL3, G3 and IU-FSU parameter sets of relativistic mean-field models. These models being consistent with the properties of cold NM, have also been used to study the effect of temperature by incorporating the Fermi function. The critical temperature for the liquid-gas phase transition in the symmetric NM is found to be 14.60, 15.37 and 14.50 MeV for NL3, G3 and IU-FSU parameter sets respectively, which is in excellent agreement with previous theoretical and experimental studies. We inspect that the properties related to second differential coefficient of the binding energy and free symmetry energy at saturation density ( i.e. K 0 (n, T ) and Q sym,0) exhibit the contrary effects for NL3 and G3 parameters as the temperature increases. We find that the prediction of saturated curvature parameter ( K sym,0 ) for G3 equation of state at finite temperature favour the combined analysis of K sym,0 for the existence of massive pulsars, gravitational waves from GW170817 and NICER observations of PSR J0030+0451. Further, we investigate the cooling mechanism of newly born stars through neutrino emissivity controlled by direct Urca process and instate some interesting remarks about neutrino emissivity. We also deliberate the effect of temperature on the M-R profile of Proto-Neutron star.

description: A short review of the problems with the action for massive gravitons is presented. We show that consistency problems could be resolved by employing spontaneous symmetry breaking to give masses to gravitons. The idea is then generalized by enlarging the SL(2,C) symmetry to $SL(2N,C)x SL(2N,C) which is broken to $SL(2,C) spontaneously through a non-linear realization. The requirement that the space-time metric is generated dynamically forces the action constructed to be a four-form. It is shown that the spectrum of this model consists of two sets of massive matrix gravitons in the adjoint representation of SU(N) and thus are colored, as well as two singlets, one describing a massive graviton, the other being the familiar massless graviton.

description: In this paper, we propose a location-allocation model with two objectives including minimizing the establishment cost of facilities and minimizing the waiting time of customers. We assume two types of servers providing primary and secondary services at each facility. The number of servers of each type is known and they should be allocated to facilities. It is clear that each facility must accommodate at least one server of each type. Customers patronize the nearest server of each type. We design some numerical examples and utilize multi-objective solution techniques for solving and analyzing the problem. © IEOM Society International

description: Polymeric graphitic carbon nitride materials have attracted significant interest in recent years and found applications in diverse light-to-energy conversions such as artificial photosynthesis, CO2 reduction or degradation of organic pollutants. However, their utilization in synthetic photocatalysis especially in the direct functionalization of C(sp3)−H bonds remains underexplored. Herein, we report mesoporous graphitic carbon nitride (mpg-CN) as a heterogeneous organic semiconductor photocatalyst for direct arylation of sp3 C−H bonds via a combination of hydrogen atom transfer and nickel catalysis. Our protocol has a broad synthetic scope (>70 examples including late-stage modification of densely functionalized bio-active molecules), is operationally simple, and shows high chemo- and regioselectivity. Facile separation and recycling of the mpg-CN catalyst in combination with its low preparation cost, innate photochemical stability and low toxicity are beneficial features overcoming typical shortcomings of homogeneous photocatalysis. Additionally, mechanistic investigations indicate that an unprecedented energy transfer process (EnT) from the organic semiconductor to the nickel complex is operating.

description: The aim of the study was to analyse the changes in the Polish foreign trade of ornamental plants since 2005, after a full year of membership in the EU. The direction and dynamics of changes in export and import, the structure of assortment and trade balance, both in terms of value and quantity, were studied. The changes and relationships between import and export prices were analyzed, as well. Studies have shown a steady increase in turnover, faster in imports in value terms, while exports in quantity terms, with a negative trade balance. Poland is a growing net importer mainly of fresh cut flowers, pot plants and flower bulbs. However the importance of nursery plants increases in import, which are also the basis for Polish exports. Poland sells more and more of them, but at ever lower prices. In the case of other plant groups an increase in export prices is observed, but they are still lower than in imports. / Synopsis. Celem pracy było zbadanie zmian w polskim handlu zagranicznym roślinami ozdobnymi od 2005r., czyli pierwszego pełnego roku członkostwa w UE. Badano kierunek i dynamikę zmian w eksporcie i imporcie, strukturę asortymentową oraz saldo obrotów, zarówno w ujęciu wartościowym, jak i ilościowym. Analizowano także zmiany i relacje cen importowych i eksportowych. Badania wykazały stały wzrost obrotów, szybszy importu w ujęciu wartościowym, zaś eksportu w ilościowym, przy ujemnym bilansie. Polska jest rosnącym importerem netto głównie kwiatów ciętych żywych, doniczkowych i cebul kwiatowych Wzrasta także w imporcie znaczenie roślin szkółkarskich, będących równocześnie podstawą polskiego eksportu. Eksportuje się ich coraz więcej, ale po coraz niższych cenach. W przypadku pozostałych grup roślin odnotowano wyraźny wzrost cen w eksporcie, ale w dalszym ciągu są niższe niż w imporcie.

description: We study the scattering of neutrinos on polarized and unpolarized free nucleons, and also the polarization of recoil particles in these scatters. In contrast to electromagnetic processes, the parity-violating weak interaction gives rise to large spin asymmetries at leading order. Future polarization measurements could provide independent access to the proton axial structure and allow the first extraction of the pseudoscalar form factor from neutrino data without the conventional partially conserved axial current (PCAC) ansatz and assumptions about the pion-pole dominance. The pseudoscalar form factor can be accessed with precise measurements with muon (anti)neutrinos of a few hundreds $\mathrm{MeV}$ of energy or with tau (anti)neutrinos. The axial form factor can be extracted from scattering measurements using accelerator neutrinos of all energies.

title: Teachers’ professional learning: perspectives and reflections of practising teachers
Creators: name: Loneragan, Damian James
Publisher: name: The Open University
Year: 2016

description: This thesis uses a case study to explore teachers’ professional learning in one secondary school in the south of England. An interpretive, qualitative case study approach was adopted. Data were collected using semi-structured interviews, questionnaires and staff biographies to explore the key research questions. These investigated how the teachers perceive their own learning and development, what teachers think they learn and develop and what activities impact teachers’ learning and development. A review of the conceptual frameworks focused on three different areas. Firstly, a consideration of how teachers and adults define their own learning. Secondly teachers’ knowledge and skills base were explored; looking in particular at what authors argue constitute teachers’ knowledge. Finally, there was an overview of the varied activities and experiences that affect and impact teachers’ learning. Analysis of the data indicated that secondary school teachers perceive their learning through the lens of acquisition and a new perspective described by participants as ‘developmental’. The teachers in the study also showed that those who had been teaching for longer had different perceptions of learning from those with less experience. A teacher’s knowledge base was considered to consist of knowledge and skills related to the school, subject and personal efficacy of the teacher. The content of teachers’ knowledge, however, was influenced by external factors such as policy and social changes in education. Finally, the study found that teachers learnt from a wide range of formal and informal activities. Formal activities tended to be less successful if the aims were not shared and the teachers felt the learning was imposed. Informal activities were more successful as they were normally instigated by staff with their own professional development in mind. Drawing together these findings the study proposes a new model of teacher learning.
Quantum interactions with pulses of radiation

description: This article presents a general master equation formalism for the interaction between travelling pulses of quantum radiation and localized quantum systems. Traveling fields populate a continuum of free space radiation modes and the Jaynes-Cummings model, valid for a discrete eigenmode of a cavity, does not apply. We develop a complete input-output theory to describe the driving of quantum systems by arbitrary incident pulses of radiation and the quantum state of the field emitted into any desired outgoing temporal mode. Our theory is applicable to the transformation and interaction of pulses of radiation by their coupling to a wide class of material quantum systems. We discuss the most essential differences between quantum interactions with pulses and with discrete radiative eigenmodes and present examples relevant to quantum information protocols with optical, microwave and acoustic waves.

description: Red and blue galaxies are traditionally classified using some specific cuts in colour or other galaxy properties, which are supported by empirical arguments. The vagueness associated with such cuts are likely to introduce a significant contamination in these samples. Fuzzy sets are vague boundary sets which can efficiently capture the classification uncertainty in the absence of any precise boundary. We propose a method for classification of galaxies according to their colours using fuzzy set theory. We use data from the SDSS to construct a fuzzy set for red galaxies with its members having different degrees of `redness'. We show that the fuzzy sets for the blue and green galaxies can be obtained from it using different fuzzy operations. We also explore the possibility of using fuzzy relation to study the relationship between different galaxy properties and discuss its strengths and limitations.

description: As a myriad of student-centred practices in primary science education have been established as valuable, effective cornerstones of teachers’ repertoires, there is now space to further consider student choice in science education. This paper seeks to examine the role of student choice in primary science education by exploring the relationship between primary teachers’ attitudes towards student-choice (minimal, emergent, and planned) and their science teaching efficacy beliefs and reported science teaching practices. A sample of 206 Australian primary teachers responded to a digital quantitative survey comprised of items that included professional demographics, the Science Teaching Efficacy Belief Instrument A (STEBI-A), science teaching approaches, and student-choice in science teaching. Descriptive statistics, T-tests, ANOVAs and Chi Squares were used in data analysis. The results showed that teachers who reportedly embraced student-choice were more efficacious and reported more expansive arrays of science teaching approaches than those who purported to minimise choice. Although there is a need for follow-up proximal research to elucidate these findings, some speculative interpretations and recommendations are discussed.

description: To make sound science-related decisions in a global society, individuals must possess a science identity, or see themselves as capable of doing and understanding science. Science identity development begins in school-aged years, when multilingual students (MLs) are often marginalised in the classroom due to language challenges and low expectations placed on them. This descriptive multiple case study explores the science identities expressed by six US high school MLs in their biology classrooms. Data from semi structured interviews were analysed through qualitative coding methods. Secondary data sources included field notes from observations conducted in each student’s classroom six times during the school year. Results revealed that all MLs expressed science identity indicators, including feeling like a scientist, having a personal interest in science, and seeing science as related to their worlds. Other important identity indicators were not expressed among all students, such as views of themselves as ‘good’ science students, doing or using science outside of school, and career aspirations. Over half of MLs cited language as a direct barrier to their science identities. The study makes several contributions to the field of science education, which are detailed. Implications are presented for nurturing MLs’ science identities in the formal classroom.

description: We show that in excitonic insulators with $s$-wave electron-hole pairing, an applied electric field (either pulsed or static) can induce a $p$-wave component to the order parameter, and further drive it to rotate in the $s+ip$ plane, realizing a Thouless charge pump. In one dimension, each cycle of rotation pumps exactly two electrons across the sample. Higher dimensional systems can be viewed as a stack of one dimensional chains in momentum space in which each chain crossing the fermi surface contributes a channel of charge pumping. Physics beyond the adiabatic limit, including in particular dissipative effects is discussed.

We present here the method we developed to generate Stereographic Maps directly from a metal's Fermi Surface, based on the Lifshitz model and the recent advances by S.P. Novikov and his pupils. As an application, we test the method with an interesting toy model and then with Au and Ag.

description: Linen is known in the world since the beginning of civilization. In Poland, it has been cultivated for decades, and recently there has been increased interest in linseed oil. Because of the valuable properties of linseed oil and the ability to use it as a raw material for production of biofuels, it could be expected that the importance of linseed will increase. The article describes linseed and linseed oil. It presents their market in the world and in Poland. The major producers of linseed and their percentage share in global cultivation are identified. The paper defines world leaders in export and import of linseed and linseed oil. It also illustrates changes in linseed cultivation, as well as the production of linseed oil in Poland. In addition, data on imports and exports were collected and interpreted. / Synopsis. Len znany jest na świecie już od początków cywilizacji.

description: Past and current institutional cultures have contributed to the overrepresentation of white men in geoscience. Acknowledging and learning from this history is critical to building a forward-looking, innovative, and anti-racist geoscience community. To change institutional culture and address inequities and exclusion, the first step for many institutions is to establish a committee or task force focused on diversity, equity, and inclusion. In this manuscript, we reflect on our successes, challenges, and experiences co-chairing the Diversity, Equity, and Inclusion Task Force at Columbia University’s Lamont-Doherty Earth Observatory in 2020. We organized a transparent, community-driven effort that lasted for six months with clear expectations around outcomes. We identified priorities, goals, and recommendations for institutional change, ranging from large-scale structural changes to individual actions. Specifically, we found that (1) considering power dynamics, (2) striking a balance between tone and content, (3) addressing how financial constraints intersect with institutional values, and (4) respecting the power and politics of data were critical to our work. Here we present a roadmap for creating robust and visionary institutional change. In addition, we discuss the obstacles, barriers, and opportunities we encountered through our process, in order to provide strategies that other institutions can use to address their own needs, and to advance justice in geoscience as a whole. Moreover, we discuss how this structure and lessons learned are broadly applicable to academic institutions at various scales and beyond geoscience.

description: We propose a QCD based many-body model for the nucleus where the strong coupling regime is controlled by a three body string force and the weak coupling regime is dominated by a pairing force. This model operates effectively with a quark-gluon Lagrangian containing a pairing force from instantons and a baryonic string term which contains a confining potential. The unified model for weak and strong coupling regimes, is, however, only consistent at the border of perturbative QCD. The baryonic string force is necessary, as a {stability and} compressibility analysis shows, for the occurrence of the phases of nuclear matter. The model exhibits a quark deconfinement transition and chiral restoration which are suggested by QCD and give qualitatively correct numerics. The effective model is shown to be isomorphic to the Nambu-Jona-Lasinio model and exhibits the correct chirality provided that the chiral fields are identified with the 2-particle strings, which are natural in a QCD framework

description: Precision beekeeping allows to monitor bees' living conditions by equipping beehives with sensors. The data recorded by these hives can be analyzed by machine learning models to learn behavioral patterns of or search for unusual events in bee colonies. One typical target is the early detection of bee swarming as apiarists want to avoid this due to economical reasons. Advanced methods should be able to detect any other unusual or abnormal behavior arising from illness of bees or from technical reasons, e.g. sensor failure. In this position paper we present an autoencoder, a deep learning model, which detects any type of anomaly in data independent of its origin. Our model is able to reveal the same swarms as a simple rule-based swarm detection algorithm but is also triggered by any other anomaly. We evaluated our model on real world data sets that were collected on different hives and with different sensor setups.

Microbial metabolism of abietane diterpenoids by Pseudomonas abietaniphila BKME-9 and Burkholderia xenovorans LB400
Creators: name: Smith, Daryl James

description: This dissertation has elucidated initial steps in the degradation of abietane diterpenoids by Pseudomanas abietaniphila BKME-9 and Burkholderia xenovorans LB400. A 10.4-kbp extension of the dit cluster in BKME-9 containing genes involved in abietane diterpenoid degradation has been sequenced. The ditQ gene was found to encode a cytochrome P450 monooxygenase. Knocking out ditQ had little effect on growth of BKME-9 on abietic acid (AbA) but impaired growth on dehydroabietic acid (DM) and palustric acid (PaA). A xylE transcriptional fusion showed that a range of diterpenoids induced transcription of ditQ. Substrate binding assays of DitQ revealed that DhA binds to the enzyme (Kd = 0.43 ± 0.03 μM). These results indicate that DitQ is involved in the metabolism of DhA and PaA and are consistent with its putative role in converting DhA to 7-hydroxy-DhA. The genome of LB400 was found to contain a large cluster of genes with high similarity to the BKME-9-dit cluster. Microarray transcriptional analysis revealed that of the 72 genes encoded by an 80.5-kb cluster, 43 are up-regulated at least 2-fold in expression during growth on DhA versus on succinate. This cluster has been named the LB400 dit cluster. Through 2D gel proteomic analysis, we have determined that a key difference in the catabolism of the abietane diterpenoids, DhA and AbA lies in the differential expression of a cytochrome P450, DitU (CYP226A2) encoded by the dit cluster. DitQ was expressed during growth on both DhA and AbA, whereas DitU expression was only detectable during growth on AbA. Phenotypic studies of knockout mutants in LB400 containing insertion mutations of ditQ or ditU showed that ditQ was required for growth on DhA, whereas ditU was required for growth on AbA. In cell suspension assays, patterns of metabolite accumulation confirmed the role of DitU in AbA transformation and DitQ in DhA transformation. Substrate binding assays revealed that DitQ binds both DhA (Kd = 0.98 ± 0.01 μM) and PaA (Kd = 1.6 ± 0.1 μM). An in vitro P450 assay confirmed that DitQ transforms DhA to 7-hydroxy-DhA. These results demonstrate distinct roles of DitQ and DitU in the transformation of DhA and AbA to the central intermediate, 7-oxo-DhA, in a convergent degradation pathway.

description: We compute the charm quark mass in lattice QCD and compare different formulations of the heavy quark, and quenched data to that with dynamical sea quarks. We take the continuum limit of the quenched data by extrapolating from three different lattice spacings, and compare to data with two flavours of dynamical sea quarks with a mass around the strange at the coarsest lattice spacing. Both the FNAL and ALPHA formalism are used. We find the different heavy quark formulations have the same continuum limit in the quenched approximation, and limited evidence that this approximation overestimates the charm quark mass.

description: Two sources of geometric information are encoded in the galaxy power spectrum: the sound horizon at recombination and the horizon at matter-radiation equality. Analyzing the BOSS DR12 galaxy power spectra using perturbation theory with $Ω_m$ priors from Pantheon supernovae but no priors on $Ω_b$, we obtain constraints on $H_0$ from the second scale, finding $H_0 = 65.1^{+3.0}_{-5.4}\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$; this differs from the best-fit of SH0ES at 95\% confidence. Similar results are obtained if $Ω_m$ is constrained from uncalibrated BAO: $H_0 = 65.6^{+3.4}_{-5.5}\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$. Adding the analogous lensing results from Baxter \& Sherwin 2020, the posterior shifts to $70.6^{+3.7}_{-5.0}\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$. Using mock data, Fisher analyses, and scale-cuts, we demonstrate that our constraints do not receive significant information from the sound horizon scale. Since many models resolve the $H_0$ controversy by adding new physics to alter the sound horizon, our measurements are a consistency test for standard cosmology before recombination. A simple forecast indicates that such constraints could reach $σ_{H_0} \simeq 1.6\,\mathrm{km}\,\mathrm{s}^{-1}\mathrm{Mpc}^{-1}$ in the era of Euclid.
