description: The second-order modified Dirac equation leading to the modified dispersion relation due to the Lorentz invariance violation corrections is suggested. The equation is formulated in the 16-component first- order form. I have obtained the projection matrix extracting solutions of the equation with definite spin projections which can be considered as the density matrix for pure spin states. Exact solutions of the equation are found for particles in the external constant and uniform magnetic field. The synchrotron radiation radius within the novel modified Dirac equation is estimated.

Carbon, water and energy exchange from an old growth mountain ash forest
Creators: name: MUSA KILINC
Publisher: name: Monash University

Subjects: Geography

description: Increases in atmospheric C02 concentration are projected to have substantial impacts on climate and the growth dynamics of forest ecosystems. Therefore, knowledge about the current distribution, magnitude and the processes that control the terrestrial carbon sink are essential to predict the future responses of ecosystems to global environmental change. Old growth forests are of particular relevance with respect to the long-term permanence of forest carbon sinks since little is known about the annual carbon sink/source status of these ecosystems. Therefore, this thesis investigates the carbon, water and energy exchanges from an old growth Mountain Ash (Eucalyptus regnans) ecosystem. This is achieved through an integrated approach combining eddy covariance flux measurements above and below the canopy and in situ measurements.

The research conducted for this dissertation initially explored the robustness and data quality of eddy covariance (EC) flux measurements over a tall old growth Mountain Ash forest located in south eastern Australia. One such quality assessment is the surface energy balance (SEB) closure as it indicates the amount of turbulent energy exchange captured by the EC instrumentation. This investigation measured and modeled storage components over half hourly periods, as well as evaluated the spectral signal of the turbulent flux exchange over different averaging periods. Accounting for all the storage terms in the radiation balance suggested that 93% of the turbulent fluxes were captured. Although this initial quality assessment indicated that the flux measurements were reliable, night time ecosystem respiration (Re) measurements are typically underestimated using the EC technique at many flux sites. Therefore, Re and its components (belowground, leaf, wood) were measured and scaled up using chamber based techniques and compared to Re derived from EC night timedata. Results showed that annual Re estimate from the eddy flux tower was 13% lower than scaled chamber based estimates. [...]
Isomorphisms of types in the presence of higher-order references (extended version)

description: We investigate the problem of type isomorphisms in the presence of higher-order references. We first introduce a finitary programming language with sum types and higher-order references, for which we build a fully abstract games model following the work of Abramsky, Honda and McCusker. Solving an open problem by Laurent, we show that two finitely branching arenas are isomorphic if and only if they are geometrically the same, up to renaming of moves (Laurent's forest isomorphism). We deduce from this an equational theory characterizing isomorphisms of types in our language. We show however that Laurent's conjecture does not hold on infinitely branching arenas, yielding new non-trivial type isomorphisms in a variant of our language with natural numbers.

description: Dynamic structural transitions within the seven-transmembrane bundle represent the mechanism by which G-protein-coupled receptors convert an extracellular chemical signal into an intracellular biological function. Here, the conformational dynamics of the neuropeptide Y receptor type 2 (Y2R) during activation was investigated. The apo, full agonist-, and arrestin-bound states of Y2R were prepared by cell-free expression, functional refolding, and reconstitution into lipid membranes. To study conformational transitions between these states, all six tryptophans of Y2R were(13)C-labeled. NMR-signal assignment was achieved by dynamic-nuclear-polarization enhancement and the individual functional states of the receptor were characterized by monitoring(13)C NMR chemical shifts. Activation of Y2R is mediated by molecular switches involving the toggle switch residue Trp281(6.48)of the highly conserved SWLP motif and Trp327(7.55)adjacent to the NPxxY motif. Furthermore, a conformationally preserved "cysteine lock"-Trp116(23.50)was identified.

description: In an interdisciplinary project, object-specific desalination methods have been developed and carried out on seven prominent burial monuments and two mausoleums at the Bartholomew Cemetery in Goettingen (Germany). The monuments were constructed from the local sandstone (Buntsandstein). The methods discussed in this study are desalination in a water bath, cyclical sprinkling and capillary flow desalination. To verify the effectiveness of the applied methods, the salt content in the rinse-fluids were measured during the salt reduction process. Furthermore, the salt content was measured on eluted drill cuttings samples before and after the salt lowering procedure. Determination of salt impact was carried out by measurement with an ion chromatograph and by electrical conductivity. The different salt phases were determined by means of x-ray diffractometry analysis. The primary purpose of the project was to optimise the efficiency of the desalination treatments to further a sustainable conservation of the monuments.

description: Does information play a significant role in the foundations of physics? Information is the abstraction that allows us to refer to the states of systems when we choose to ignore the systems themselves. This is only possible in very particular frameworks, like in classical or quantum theory, or more generally, whenever there exists an information unit such that the state of any system can be reversibly encoded in a sufficient number of such units. In this work we show how the abstract formalism of quantum theory can be deduced solely from the existence of an information unit with suitable properties, together with two further natural assumptions: the continuity and reversibility of dynamics, and the possibility of characterizing the state of a composite system by local measurements. This constitutes a new set of postulates for quantum theory with a simple and direct physical meaning, like the ones of special relativity or thermodynamics, and it articulates a strong connection between physics and information.

description: For electronic excitations in the ultraviolet and visible range of the electromagnetic spectrum, the intensities are usually calculated within the dipole approximation, which assumes that the oscillating electric field is constant over the whole molecule. For the short wavelengths used in X-ray spectroscopy, this dipole approximation breaks down and it becomes necessary to include higher-order contributions. In quantum-chemical approaches to X-ray spectroscopy, these so-called quadrupole intensities have so far been calculated by including contributions depending on the square of the electric-quadrupole and magnetic-dipole transition moments. However, the resulting quadrupole intensities depend on the choice of the origin of the coordinate system. Here, we show that for obtaining an origin-independent theory, one has to include all contributions that are of the same order in the wave vector consistently. This leads to two additional contributions depending on products of the electric-dipole and electric-octupole and of the electric-dipole and magnetic-quadrupole transition moments, respectively. We have implemented such an origin-independent calculation of quadrupole intensities in X-ray absorption spectroscopy (XAS) within time-dependent density-functional theory, and demonstrate its usefulness for the calculation of metal and ligand K-edge XAS spectra of transition metal complexes.

description: The topographic features at the cell–material biointerface are critical for cellular sensing of the extracellular environment (ECM) and have gradually been recognized as key factors that regulate cell adhesion behavior. Herein, a well-defined nanostructured biointerface is fabricated via a new generation of mussel-inspired polymer coating to mimic the native ECM structures. Upon the bioinert background presence and biospecific ligands conjugation, the affinity of cancer cells to the resulting biofunctional surfaces, which integrate topographic features and biochemical cues, is greatly strengthened. Both the conjugated bioligand density, filopodia formation, and focal adhesion expression are significantly enhanced by the surficial nano-features with an optimized size-scale. Thus, this nanostructured biointerface exhibits high capture efficiency for circulating tumor cells (CTCs) with high sensitivity, high biospecificity, and high purity. Benefiting from the unique bioligands conjugation chemistry herein, the captured cancer cells can be responsively detached from the biointerfaces without damage for downstream analysis. The present biofunctional nanostructured interfaces offer a good solution to address current challenges to efficiently isolate rare CTCs from blood samples for earlier cancer diagnosis.

description: We investigate the superfluid-insulator quantum phase transition of one-dimensional bosons with off-diagonal disorder by means of large-scale Monte-Carlo simulations. For weak disorder, we find the transition to be in the same universality class as the superfluid-Mott insulator transition of the clean system. The nature of the transition changes for stronger disorder. Beyond a critical disorder strength, we find nonuniversal, disorder-dependent critical behavior. We compare our results to recent perturbative and strong-disorder renormalization group predictions. We also discuss experimental implications as well as extensions of our results to other systems.

Conceptual Framework Of The Active Ageing Policies In Employment In Poland

Subjects: Active Ageing

description: The aim of this work is to present an in depth understanding of the conceptual framework of active ageing policies, which have been created and implemented in Poland. The discussion of active ageing in employment in Poland started relatively late. The first discussions on the unfavourable situation of elderly employment emerged only in the second half of the 1990s, when the debate on the pension system reform started. While only a few ageing policies were developed at the national level during that time, several interesting initiatives were undertaken at a regional level and in the third sector. They were mostly focused on productive ageing and the problems associated with the economic activation of people over 50. The intensive implementation of the active ageing policies in Poland started in 2012, during the European Year of Active Ageing. At present, there is an intense discussion on policies addressed to the elderly, which concentrate not only on the activation of the labour market, but also on healthy, active and socially inclusive ageing, education andcivil engagement.

This paper concludes that despite intense work being done by public authorities, the concept still needs a deeper implementation - especially at the regional level. Furthermore, close observation and evaluation of the activation programmes is still missing and the identification and implementation of good practices which are already being developed in other European countries is under-used.

It is demonstrated that the magnetic ground state is a {\it microscopic} coexistence of antiferromagnetic and a spin-glass orders. This speromagnet-like phase features frozen-in short-range fluctuations of the Fe$^{3+}$ magnetic moments that are transverse to the long-range ordered antiferromagnetic spin component.

description: The aim of this report is a deepened recognition of employment in long-term care (LTC). It presents past and future trends in the development of LTC employment. Authors collected scattered statistical information, estimated lacking data and projected future growth in the number of employed in care services. Performed analysis includes employment in the health and social sector and across various types of care. Projections of the demand for care and supply of the LTC workforce are based on the demographic prognosis of the population size and changes in the age structure taking into account different scenarios for demographic development. Results show the growing gap between demand and supply in the LTC employment. The policy towards aging in Poland must take up the challenge of growing care needs, family changes and lower opportunities for provision of informal care.

description: Background: The current study aims at better characterizing the role of reading skills as a predictor of comprehension of relative clauses. Well-established cross-linguistic evidence shows that children are more accurate in the comprehension of subject-extracted relative clauses in comparison to the object-extracted counterpart. Children with reading difficulties are known to perform less accurately on object relatives at the group level compared to typically developing children. Given that children’s performance on reading tasks is shown to shape as a continuum, in the current study we attempted to use reading skills as a continuous variable to predict performance on relative clauses. Methods: We examined the comprehension of relative clauses in a group of 30 English children (7–11 years) with varying levels of reading skills. Reading skills varied on a large spectrum, from poor readers to very skilled readers, as assessed by the YARC standardized test. The experimental task consisted of a picture-matching task. Children were presented with subject and object relative clauses and they were asked to choose one picture - out of four - that would best represent the sentence they heard. At the same time, we manipulated whether the subject and object nouns were either matching (both singular or both plural) or mismatching (one singular, the other plural) in number. Results: Our analysis of accuracy shows that subject relatives were comprehended more accurately overall than object relatives, that responses to sentences with noun phrases mismatching in number were more accurate overall than the ones with matching noun phrases and that performance improved as a function of reading skills. Within the match subset, while the difference in accuracy between subject and object relatives is large in poor readers, the difference is reduced with better reading skills, almost disappearing in very skilled readers. Discussion: Beside replicating the well-established findings on the subject-object asymmetry, number facilitation in the comprehension of relative clauses, and a better overall performance by skilled readers, these results indicate that strong reading skills may determine a reduction of the processing difficulty associated with the hardest object relative clause condition (i.e., match), causing a reduction of the subject-object asymmetry.

description: We discuss the Borel Tukey ordering on cardinal invariants of the continuum. We observe that this ordering makes sense for a larger class of cardinals than has previously been considered. We then provide a Borel version of a large portion of van Douwen's diagram. For instance, although the usual proof of the inequality $\mathfrak p\leq\mathfrak b$ does not provide a Borel Tukey map, we show that in fact there is one. Afterwards, we revisit a result of Mildenberger concerning a generalization of the unsplitting and splitting numbers. Lastly, we show that the inclusion ordering on $\mathcal P(ω)$ embeds into the Borel Tukey ordering on cardinal invariants.

description: Poultry immunity, health, and production are several factors that challenge the future growth of the poultry industry. Consumer confidence, product quality and safety, types of products, and the emergence and re-emergence of diseases will continue to be major challenges to the current situation and the strategic future of the industry. Foodborne and zoonotic diseases are strictly linked with poultry. Eradication, elimination, and/or control of foodborne and zoonotic pathogens present a major challenge to the poultry industry. In addition, the public health hazards from consuming foods with high antibiotic residues will remain a critical issue. The theory of poultry production described in this review will not be limited to considering disease control. Rather, it will also incorporate the interconnection of the animals' health, welfare, and immunity. It is essential to know that chickens are not susceptible to intranasal infection by the SARS-CoV-2 (COVID-19) virus. Nevertheless, the COVID-19 pandemic will affect poultry consumption, transport, and the economics of poultry farming. It will also take into consideration economic, ethical, social dimensions, and the sustenance of the accomplishment of high environmental security. Stockholders, veterinarians, farmers, and all the partners of the chain of poultry production need to be more involved in the current situation and the strategic future of the industry to fulfill human demands and ensure sustainable agriculture. Thus, the present review explores these important tasks.

description: This paper introduces a new model to generate rhythmically relevant non-verbal facial behaviors for virtual agents while they speak. The model demonstrates perceived performance comparable to behaviors directly extracted from the data and replayed on a virtual agent, in terms of synchronization with speech and believability. Interestingly, we found that training the model with two different sets of data, instead of one, did not necessarily improve its performance. The expressiveness of the people in the dataset and the shooting conditions are key elements. We also show that employing an adversarial model, in which fabricated fake examples are introduced during the training phase, increases the perception of synchronization with speech.

description: The Inter-University Centre for Astronomy and Astrophysics (IUCAA) is an autonomous institution set up by the University Grants Commission (UGC) of India to promote the nucleation and growth of active groups in astronomy and astrophysics at Indian universities. It was established in 1988 at Pune, India. IUCAA aims to be a centre of excellence within the university sector for teaching, research and development in astronomy and astrophysics. To highlight IUCAA Associates program and associates output during their tenure as an associate, we decided to study its academic scientific output of IUCAA Associates during 2003-2013. This paper is an Informetric analysis of 1009 papers published by IUCAA associates from 2003 to 2013, downloaded from the institute’s website, annual reports and ADS. There is no doubt that collaboration is a common phenomenon in research. This paper examined the collaborative strength and patterns of authorship among IUCAA associates, covering a period of 10 years. The results of the data were analyzed based on the number of articles published per year, pattern of authorship and the collaborative degree and strength of authors. The study shows that majority of the associates preferred to publish research papers in joint authorship. Out of 1009  articles, 950 (93.32%) are joint works while only 68 (6.68%) are single authored works. The degree of author’s collaboration was also calculated to be 0.93, while the mean numbers of single authored and joint authored article are 6.68 and 93.32  respectively. Further, the study investigated highly prolific authors and highly preferred journals by the IUCAA associates during the study period.

description: The path integral, which generates in-in correlation functions of a scalar field in a cosmological spacetime, is shown to admit nontrivial classical solutions as stationary phases. Although the solutions exist for Lorentzian signature, their contribution to the path integral is reminiscent that of the instantons in Euclidean field theories. When the scalar potential has more than one locally stable vacua, the correlation functions receive contributions from all of them via these instanton-like configurations, which is similar to tunneling. We present some explicit solutions for toy models and discuss possible implications of our results.

description: How is access to the Elsewhere facilitated through affective pedagogy in a contemporary Sufi setting in Germany? This article draws analytical lessons from Inayati healing seminars that took place in the summer of 2013. Participants were instructed to feel the Elsewhere of 'inner space' in the material/corporeal realities by attuning to breath, sonic resonance, collective movement, and attentive listening. The affective pedagogy of the teacher extended the spatial-temporal coordinates of the Elsewhere (as framed by Mittermaier) to include 'fleeting affects' among its unknown elements. These pedagogic tactics entangled religious and secular life-worlds with aesthetic and therapeutic traditions. Learning to feel the unknown affects emanating from the Elsewhere in this setting aimed to provide existential resources to cope with the everyday struggles of post-secular life.

description: We investigate the contribution of star-forming galaxies to the ionizing background at z~3, building on previous work based on narrowband (NB3640) imaging in the SSA22a field. We use new Keck/LRIS spectra of Lyman break galaxies (LBGs) and narrowband-selected Lya emitters (LAEs) to measure redshifts for 16 LBGs and 87 LAEs at z>3.055, such that our NB3640 imaging probes the Lyman-continuum (LyC) region. When we include the existing set of spectroscopically-confirmed LBGs, our total sample with z>3.055 consists of 41 LBGs and 91 LAEs, of which nine LBGs and 20 LAEs are detected in our NB3640 image. With our combined imaging and spectroscopic data sets, we critically investigate the origin of NB3640 emission for detected LBGs and LAEs. We remove from our samples 3 LBGs and 3 LAEs with spectroscopic evidence of contamination of their NB3640 flux by foreground galaxies, and statistically model the effects of additional, unidentified foreground contaminants. The resulting contamination and LyC-detection rates, respectively, are 62 +/-13% and 8 +/-3% for our LBG sample, and 47 +/-10% and 12 +/-2% for our LAE sample. The corresponding ratios of non-ionizing UV to LyC flux-density, corrected for intergalactic medium (IGM) attenuation, are 18.0 +34.8/-7.4 for LBGs, and 3.7 +2.5/-1.1 for LAEs. We use these ratios to estimate the total contribution of star-forming galaxies to the ionizing background and the hydrogen photoionization rate in the IGM, finding values larger than, but consistent with, those measured in the Lya forest. Finally, the measured UV to LyC flux-density ratios imply model-dependent LyC escape fractions of f_{esc}^{LyC} ~ 5-7% for our LBG sample and f_{esc}^{LyC} ~ 10-30% for our fainter LAE sample.

description: The ways in which ideas of the book intersect with notions of space are manifold from Antiquity onwards. As vessels of ideas and knowledge, books and their use invited spatial metaphors based on notions of collecting and storage which were closely bound to the idea of memory.1 The notion of the book as space surfaces in metaphors of the book as a garden, library or building throughout the Middle Ages. For Christian writers, notions such as the ‘inner library,’ the heart as a library of Christ are central, and they pervade patristic texts.2 Accordingly, the metaphorical realm of books connects the book and the body, and is not necessarily spatial in a dimensional sense. It goes beyond the specific object of scroll or codex, aiming instead at the texts and their use and reception.
title: MAD MEN AND WOMEN IN THE OFFICE. Sex and gender in the workplace
Creators: name: Wiegel, Maria
Publisher: name: ZZF - Centre for Contemporary History: Zeitgeschichte online
Year: 2022

description: By using a 60s workplace as its setting, Matthew Weiner’s Mad Men (2007-2015) does not merely provide insight into historical gender and sex relations in the workplace of the 60s. It also reflects current sex and gender relations in the workplace of 21st century America (e.g. the #MeToo Movement). As Sara Rogers, leaning on Horace Newcomb and Paul Hirsch, argues, tv shows’ strength lies in their raising questions, rather than answering them. This is precisely what Mad Men, with its representation of 1960s sex and gender dynamics does. In the following blogpost I will show that Weiner’s hit show is very aware of – among others – Helen Gurley Brown’s influence on the American workplace of the 60s and that it uses its nostalgic effect for reflecting contemporary sex and gender relations in the workplace.

description: We construct continuum models of 3D and 4D topological insulators by coupling spin-1/2 fermions to an SU(2) background gauge field, which is equivalent to a spatially dependent spin-orbit coupling. Higher dimensional generalizations of flat Landau levels are obtained in the Landau-like gauge. The 2D helical Dirac modes with opposite helicities and 3D Weyl modes with opposite chiralities are spatially separated along the third and fourth dimensions, respectively. Stable 2D helical Fermi surfaces and 3D chiral Fermi surfaces appear on open boundaries, respectively. The charge pumping in 4D Landau level systems shows quantized 4D quantum Hall effect.

description: The mechanisms of linezolid resistance among 13 E. faecalis and 6 E. faecium isolates, recovered from six Spanish hospitals during 2017–2018, were investigated. The presence of acquired linezolid resistance genes and mutations in 23S rDNA and in genes encoding for ribosomal proteins was analyzed by PCR and amplicon sequencing. Moreover, the susceptibility to 18 antimicrobial agents was investigated, and the respective molecular background was elucidated by PCR-amplicon sequencing and whole genome sequencing. The transferability of the linezolid resistance genes was evaluated by filter-mating experiments. The optrA gene was detected in all 13 E. faecalis isolates; and one optrA-positive isolate also carried the recently described cfr(D) gene. Moreover, one E. faecalis isolate displayed the nucleotide mutation G2576T in the 23S rDNA. This mutation was also present in all six E. faecium isolates. All linezolid-resistant enterococci showed a multiresistance phenotype and harbored several antimicrobial resistance genes, as well as many virulence determinants. The fexA gene was located upstream of the optrA gene in 12 of the E. faecalis isolates. Moreover, an erm(A)-like gene was located downstream of optrA in two isolates recovered from the same hospital. The optrA gene was transferable in all but one E. faecalis isolates, in all cases along with the fexA gene. The cfr(D) gene was not transferable. The presence of optrA and mutations in the 23S rDNA are the main mechanisms of linezolid resistance among E. faecalis and E. faecium, respectively. We report the first description of the cfr(D) gene in E. faecalis. The presence of the optrA and cfr(D) genes in Spanish hospitals is a public health concern.
Optical conductivity due to orbital polarons in systems with orbital degeneracy

description: We consider the impact of orbital polarons in doped orbitally ordered systems on optical conductivity using the simplest generic model capturing the directional nature of either $t_{2g}$ (or $e_g$) orbital states in certain transition metal oxides, or $p$ orbital states of cold atoms in optical lattices. The origin of the optical transitions is analyzed in detail and we demonstrate that the optical spectra: (i) are determined by the string picture, i.e., flipped orbitals along the hole hopping path, and (ii) consist of three narrow peaks which stem from distinct excitations. They occur within the Mott-Hubbard gap similar to the superconducting cuprates but indicate hole confinement, in contrast to the spin t-J model. Finally, we point out how to use the point group symmetry to classify the optical transitions.

Testing marginal homogeneity in Hilbert spaces with applications to stock market returns

Subjects: subject: Marginal homogeneity
subject: Functional data

subject: U-statistic
subject: Cramér–von-Mises test
subject: Stock market return
subject: 310

description: This paper considers a paired data framework and discusses the question of marginal homogeneity of bivariate high-dimensional or functional data. The related testing problem can be endowed into a more general setting for paired random variables taking values in a general Hilbert space. To address this problem, a Cramér–von-Mises type test statistic is applied and a bootstrap procedure is suggested to obtain critical values and finally a consistent test. The desired properties of a bootstrap test can be derived that are asymptotic exactness under the null hypothesis and consistency under alternatives. Simulations show the quality of the test in the finite sample case. A possible application is the comparison of two possibly dependent stock market returns based on functional data. The approach is demonstrated based on historical data for different stock market indices.

When racial inequalities return: Assessing the restratification of Cuban society 60 years after revolution

subject: 300 Sozialwissenschaften::320 Politikwissenschaft::320 Politikwissenschaft

description: Few political transformations have attacked social inequalities more thoroughly than the 1959 Cuban Revolution. As the survey data in this article show, however, sixty years on, structural inequalities are returning that echo the prerevolutionary socioethnic hierarchies. While official Cuban statistics are mute about social differences along racial lines, the authors were able to conduct a unique, nationwide survey with more than one thousand respondents that shows the contrary. Amid depressed wages in the state-run economy, access to hard currency has become key. However, racialized migration patterns of the past make for highly unequal access to family remittances, and the gradual opening of private business disfavors Afro- Cubans, due to their lack of access to prerevolutionary property and startup capital. Despite the political continuity of Communist Party rule, a restructuring of Cuban society with a profound racial bias is turning back one of the proudest achievements of the revolution.
