description: We compute glueball masses for even spins ranging from 0 to 6, in the D=2+1 SU(2) lattice gauge theory. We do so over a wide range of lattice spacings, and this allows a well-controlled extrapolation to the continuum limit. When the resulting spectrum is presented in the form of a Chew-Frautschi plot we find that we can draw a straight Regge trajectory going through the lightest glueballs of spin 0, 2, 4 and 6. The slope of this trajectory is small and turns out to lie between the predictions of the adjoint-string and flux-tube glueball models. The intercept we find, α_0 ~ -1, is much lower than is needed for this leading trajectory to play a `Pomeron-like' role of the kind it is often believed to play in D=3+1. We elaborate the Regge theory of high energy scattering in 2 space dimensions, and we conclude, from the observed low intercept, that high-energy glueball scattering is not dominated by the leading Regge pole exchange, but rather by a more complex singularity structure in the region 0 <= Reλ <= 1/2 of the complex angular momentum λplane. We show that these conclusions do not change if we go to larger groups, SU(N>2), and indeed to SU(\infty), and we contrast all this with our very preliminary calculations in the D=3+1 SU(3) gauge theory.

description: Objectives: Major gynecological surgeries are indicated for the treatment of female genital pathologies. It is key to examine trends in gynecologic surgical procedures and updated recommendations by international gynecological societies to find opportunities for improvement of local guidelines. To date, a very limited number of reports have been published on the epidemiology of gynecological surgeries in Kazakhstan. Moreover, some local guidelines for gynecological conditions do not comply with the international recommendations. Thus, this study aims to investigate the prevalence, indications, and outcomes of the most common major gynecological surgeries by analyzing large-scale Kazakhstani healthcare data, and identifying possible opportunities for improvement of the local public health and clinical practice. Methods: A descriptive, population-based study among women who underwent a gynecological surgery in healthcare settings across the Republic of Kazakhstan during the period of 2014–2019 was performed. Data were collected from the Unified Nationwide Electronic Health System (UNEHS). Results: In total, 80,401 surgery cases were identified and analyzed in the UNEHS database for a period of 6 years (2014–2019). The median age of the participants was 40 years old, with 61.1% in reproductive age. The most prevalent intervention was a unilateral salpingectomy—29.4%, with 72.6% patients aged between 18–34 years. The proportion of different types of hysterectomies was 49.4%. In 20% of cases, subtotal abdominal hysterectomy was performed due to uterine leiomyoma. The proportion of laparoscopic procedures in Kazakhstani gynecological practice is as low—11.59%. Conclusions: The Kazakhstani public health and gynecological care sector should reinforce implementation of contemporary treatment methods and up-to-date policies and guidelines. The overall trends in surgical procedures performed for gynecological pathologies, including uterine leiomyoma and ectopic pregnancy treatment, should be changed in favor of the minimally invasive methods in order to adopt a fertility-sparing approach.

description: Assume that $R$ is a non-right perfect ring. Then there is a proper class of classes of (right $R$-) modules closed under transfinite extensions lying between the classes $\mathcal P _0$ of projective modules, and $\mathcal F _0$ of flat modules. These classes can be defined as variants of the class $\mathcal F \mathcal M$ of absolute flat Mittag-Leffler modules: either as their restricted versions (lying between $\mathcal P _0$ and $\mathcal F \mathcal M$), or their relative versions (between $\mathcal F \mathcal M$ and $\mathcal F _0$). In this survey, we will deal with applications of these classes in relative homological algebra and algebraic geometry.
 The classes $\mathcal P _0$ and $\mathcal F _0$ are known to provide for approximations, and minimal approximations, respectively. We will show that the classes of restricted flat relative Mittag-Leffler modules, and flat relative Mittag-Leffler modules, have rather different approximation properties: the former classes always provide for approximations, but the latter do not, except for the boundary case of $\mathcal F _0$.
 The notion of an (infinite dimensional) vector bundle is known to be Zariski local for all schemes, the key point of the proof being that projectivity ascends and descends along flat and faithfully flat ring homomorphisms, respectively. We will see that the same holds for the properties of being a $κ$-restricted flat Mittag-Leffler module for each cardinal $κ\geq \aleph_0$, and also a flat $\mathcal Q$-Mittag-Leffler module whenever $\mathcal Q$ is a definable class of finite type. Thus, as in the model case of vector bundles, Zariski locality holds for flat quasi-coherent sheaves induced by each of these classes of modules. Moreover, we will see that the notion of a locally $n$-tilting quasi-coherent sheaf is Zariski local for all $n \geq 0$.

description: A wide variety of observables indicate that maximal fluctuations in the disassembly of hot nuclei with A ~ 36 occur at an excitation energy of 5.6 +- 0.5 MeV/u and temperature of 8.3 +- 0.5 MeV. Associated with this point of maximal fluctuations are a number of quantitative indicators of apparent critical behavior. The associated caloric curve does not appear to show a flattening such as that seen for heavier systems. This suggests that, in contrast to similar signals seen for liquid-gas transitions in heavier nuclei, the observed behavior in these very light nuclei is associated with a transition much closer to the critical point.

Promoting data accessibility, visibility and sustainability in the UK: the Jisc Managing Research Data Programme

Year: 2013

description: Driven by new research objectives and opportunities requiring the interdisciplinary reuse of data as well as research funder and (increasingly) journal policies, the case for skills in research data management (RDM) is becoming clearer to researchers of all disciplines. Some disciplines are historically well-served by national data centers and perpetuate a culture of organized data deposit, management, sharing and re-use. Many other researchers, however, work in disciplines without this heritage or produce data which is not appropriate for data center hosting. Institutions face a concomitant rise in responsibility for the formulation and delivery of appropriate and accessible RDM services and infrastructure for their researchers. Across the UK, the Jisc Managing Research Data program is stimulating improved RDM practice across disciplines and staff groups via development of tailored policy, services, technical infrastructure and training. Our paper will describe the work of the program and complementary work by the Digital Curation Centre. We shall discuss emerging models in institutional approaches which may be of use elsewhere. Above all, we shall examine how data management planning and training activities may be enhanced by a consideration of disciplinary differences and suggest the benefits of drawing on expert partners beyond the institution.

description: We propose novel superfluids induced by the parity-doubled baryons. The parity-doubled baryons, i.e., a nucleon $N(940)$ with spin-parity $J^{P}=1/2^{+}$ and an excited nucleon $N^{\ast}(1535)$ with $J^{P}=1/2^{-}$ in vacuum, become degenerate at sufficiently high density where the chiral symmetry is restored. In this study, we extend the conventional $\mathrm{U}(1)$ chiral symmetry to the higher dimensional symmetries, dubbed emergent chiral symmetries, including the naive and mirror assignments as their subgroups. Starting with the Lagrangian up to four-point interactions among the neutron $n$ and its chiral partner $n^{\ast}$, neutral components in $N$ and $N^{\ast}$, in pure neutron matter, we investigate the properties of the ground state with a pairing gap generated by the $n$ and $n^{\ast}$ in the mean-field approximation. We find vector-type condensates that induce the dynamical breaking of a new class of internal symmetries, emergent chiral symmetries, as well as the baryon number and the rotational symmetries of the real space, indicating the appearance of massless Nambu-Goldstone bosons consisting of six quarks: emergent pions, superfluid phonons, and magnons, respectively. We also study the fermionic excitation modes at low-energy scales, and show that they exhibit a spatial anisotropy of the propagation at the Dirac cone in momentum space. Some phenomenological implications are advocated, shedding new light on the properties of neutron stars.

title:  Dal ne bis in idem europeo di diritto amministrativo al diritto alla buona amministrazione: un possibile itinerario di studio

Publisher: name: Roma TrE-Press

description: Si definisce ne bis in idem europeo di diritto amministrativo la convergenza sul medesimo soggetto, per lo stesso fatto, di procedimenti e/o sanzioni di natura amministrativa che, trovando fonte, diretta o indiretta, nel diritto europeo, sono catturati dall’art. 50 CDFUE. Con le recenti sentenze sui casi bpost e Nordzucker, la Grande Sezione della Corte di giustizia ha finalmente elaborato un test unitario, valido in tutte le aree del diritto europeo. Esso valorizza l’identità materiale dei fatti e prescinde dalla qualificazione giuridica della fattispecie. Al contempo, e conformemente alla giurisprudenza Menci, esso ammette deroghe al principio, ove previste per legge, rispettose dell’essenza del diritto fondamentale e proporzionate (art. 52, § 1 CDFUE). L’approdo ermeneutico appare, negli effetti, affine all’arresto dalla Grande Camera della Corte Edu nel caso A & B c. Norvegia. Il punto di equilibrio raggiunto dalle Corti sovranazionali desta sentimenti ambivalenti nella comunità penalistica e amministrativistica. La prima, abituata a confrontarsi con un principio di legalità stretta, teme un’eccessiva incertezza delle regole che presidiano l’eccezione al divieto di bis in idem. La seconda saluta con favore l’emersione di uno statuto unitario della sanzione afflittiva, salvo registrare, a posteriori, una più blanda applicazione delle garanzie penalistiche alle sanzioni amministrative. Si isolano quindi le ipotesi di ne bis in idem europeo di diritto amministrativo e si propone di guardare al diritto amministrativo – in primo luogo al principio europeo di buona amministrazione (art. 41 CDFUE) – per individuare un ventaglio di regole minime che trascendono la prospettiva sanzionatoria e trovano fondamento nella relazione autorità-libertà. Da questo angolo visuale, le sentenze bpost e Nordzucker potrebbero generare un positivo effetto di trascinamento, favorendo l’emersione di un modello di amministrazione europea attento al cittadino, prima che agli obiettivi di politica comunitaria.

After computing the chiral corrections in the heavy quark limit we show that, contrary to experiment, the mass difference in the non-strange case should be smaller.

Dynamics and efficient conversion of excitons to trions in non-uniformly strained monolayer WS$_2$

description: We investigate the transport of excitons and trions in monolayer semiconductor WS$_2$ subjected to controlled non-uniform mechanical strain. We actively control and tune the strain profiles with an AFM-based setup in which the monolayer is indented by an AFM tip. Optical spectroscopy is used to reveal the dynamics of the excited carriers. The non-uniform strain configuration locally changes the valence and conduction bands of WS$_2$, giving rise to effective forces attracting excitons and trions towards the point of maximum strain underneath the AFM tip. We observe large changes in the photoluminescence spectra of WS$_2$ under strain, which we interpret using a drift-diffusion model. We show that the transport of neutral excitons, a process that was previously thought to be efficient in non-uniformly strained 2D semiconductors and termed as "funneling", is negligible at room temperature in contrast to previous observations. Conversely, we discover that redistribution of free carriers under non-uniform strain profiles leads to highly efficient conversion of excitons to trions. Conversion efficiency reaches $\simeq 100\%$ even without electrical gating. Our results explain inconsistencies in previous experiments and pave the way towards new types of optoelectronic devices.

Legally Bound? Data Protection Legislation and Research Practice
Creators: name: Horton, Laurence

Publisher: name: Zenodo
Year: 2013

description: This paper explores how data archives provide a service facilitating the gap between legal data protection requirements and research practices. Researchers encounter legal frameworks concerning data protection in all phases of the data-lifecycle, but research practice - without due care - can clash with these frameworks. Social science archives can intervene, helping researchers navigate an environment which simultaneously pushes data sharing, and consideration of the individual's right to privacy. These aims are not mutually exclusive, but pressure on researchers to 'get it right' when collecting, storing, analyzing, and anoymizing data has never been greater. We examine how archives can intervene in stages of the data-lifecycle, against the context of German and British regulatory requirements. We propose that whilst differences exist in the substance of laws (e.g. Bundesdatenschutzgesetz and Data Protection Act), research cultures, and funding environments, archives face similar challeges in the data reuse/privacy dynamic. With research innovations such as geo-referenced data, and increasingly, cross-national collaborative projects exisiting either across national laws or outside established legal frameworks - the regulatory grounding is not firm. Here facilitiation becomes an act of setting best-practice standards as guidance and, we suggest, data archives are best suited to be guides.

description: Real-time altitude control of airborne wind energy (AWE) systems can improve performance by allowing turbines to track favorable wind speeds across a range of operating altitudes. The current work explores the performance implications of deploying an AWE system with sensor configurations that provide different amounts of data to characterize wind speed profiles. We examine various control objectives that balance trade-offs between exploration and exploitation, and use a persistence model to generate a probabilistic wind speed forecast to inform control decisions. We assess system performance by comparing power production against baselines such as omniscient control and stationary flight. We show that with few sensors, control strategies that reward exploration are favored. We also show that with comprehensive sensing, the implications of choosing a sub-optimal control strategy decrease. This work informs and motivates the need for future research exploring online learning algorithms to characterize vertical wind speed profiles.

description: We formulate lattice theories in which chiral symmetry is realized nonlinearly on the fermion fields. In this framework the fermion mass term does not break chiral symmetry. This property allows us to use the Wilson term to remove the doubler fermions while maintaining exact chiral symmetry on the lattice. Our lattice formulation enables us to address non-perturbative questions in effective field theories of baryons interacting with pions and in models involving constituent quarks interacting with pions and gluons. We show that a system containing a non-zero density of static baryons interacting with pions can be studied on the lattice without encountering complex action problems. In our formulation one can also decide non-perturbatively if the chiral quark model of Georgi and Manohar provides an appropriate low-energy description of QCD. If so, one could understand why the non-relativistic quark model works.

Generating Useful Test Data for Complex Linked Employer-employee Datasets
Creators: name: Jacobebbinghaus, Peter
Publisher: name: Zenodo
Year: 2013

description: When data access for researchers is provided via remote execution or on-site use, it can be beneficial for data users, if test datasets that mimic the structure of the original data are disseminated in advance. With these test data researchers can develop their analysis code and avoid delays due to otherwise likely syntax errors. It is not the aim of test data to provide any meaningful results or to preserve statistical inferences. Instead, it is important to maintain the structure of the data in a way that any code that is developed with these test data will also run on the original data without further modifications. Achieving this goal can be challenging and costly for complex datasets such as linked employer-employee datasets (LEED) as the links between the establishments and the employees also need to be maintained. We illustrate how useful test data can be develpoed for complex datasets in a straightforward manner at limited costs. Our apporach mainly relies on traditional statistical disclosure control (SDC) techniques such as data swapping and noise addition. The structure of the data is maintained by adding constraints on the swapping procedure.

description: The Dubna-Mainz-Taipei dynamical model for pion electromagnetic production, which can describe well the existing data from threshold up to 1 GeV photon lab energy, is presented and used to analyze the recent precision data in the $Δ$ region. We find that, within our model, the bare Delta is almost spherical while the physical Delta is oblate. The deformation is almost saturated by the pion cloud effects. We further find that up to Q^2 = 4.0 (GeV/c)^2, the extracted helicity amplitude A_{3/2} and A_{1/2} remain comparable with each other, implying that hadronic helicity is not conserved at this range of Q^2. The ratio E_{1+}/M_{1+} obtained show, starting from a small and negative value at the real photon point, a clear tendency to cross zero, and to become positive with increasing Q^2. This is a possible indication of a very slow approach toward the pQCD region. Finally, we find that the bare helicity amplitude A_{1/2} and S_{1/2}, but not A_{3/2}, starts exhibiting the scaling behavior at about Q^2 \ge 2.5 (GeV/c)^2.

description: Let $G$ be a reductive algebraic group---possibly non-connected---over a field $k$ and let $H$ be a subgroup of $G$. If $G= GL_n$ then there is a degeneration process for obtaining from $H$ a completely reducible subgroup $H'$ of $G$; one takes a limit of $H$ along a cocharacter of $G$ in an appropriate sense. We generalise this idea to arbitrary reductive $G$ using the notion of $G$-complete reducibility and results from geometric invariant theory over non-algebraically closed fields due to the authors and Herpel. Our construction produces a $G$-completely reducible subgroup $H'$ of $G$, unique up to $G(k)$-conjugacy, which we call a $k$-semisimplification of $H$. This gives a single unifying construction which extends various special cases in the literature (in particular, it agrees with the usual notion for $G= GL_n$ and with Serre's "$G$-analogue" of semisimplification for subgroups of $G(k)$). We also show that under some extra hypotheses, one can pick $H'$ in a more canonical way using the Tits Centre Conjecture for spherical buildings and/or the theory of optimal destabilising cocharacters introduced by Hesselink, Kempf and Rousseau.

description: A new design is proposed for large (up to 6-m) liquid mirror containers. The design uses Kevlar, foam and aluminum, as in previous designs, but with a different configuration that makes the container lighter, stronger and more rigid. The results of finite element analysis are presented, consisting in the deformations due to temperature changes and to weight, and in the security factor for each material when maximum constraints are applied. Tilt rigidity is also analyzed. They show that the composite material construction technique gives a good performance up to 6 meter diameters. The figures and tables contained in this paper can be used as recipes to build containers having diameters between 2 and 6 meters.

description: Strong penguin operators are singlets under the right-handed flavor symmetry group SU(3)_R. However, they do not remain singlets when the operator is embedded in (partially) quenched QCD, but instead they become linear combinations of two operators with different transformation properties under the (partially) quenched symmetry group. This is an artifact of the quenched approximation. Each of these two operators is represented by a different set of low-energy constants in the chiral effective theory. In this paper, we give analytic estimates for the leading low-energy constants, in quenched and partially quenched QCD. We conclude that the effects of quenching on Q_6 are large.

Paraná: Balsa Nova County, Papagaios river, 25°27'55"S, 49°45'58"W, January/2001, UPCB 44567 - diatom collection of the Botany Department, Universidade Federal do Parana; holotype slide UPCB 44567, designated here in Fig. 3; isotype slide ANSP GC 26818 (Academy of Natural Sciences, Philadelphia).
 Valves elliptic-lanceolate, length 26.0– 37.9 µm and breadth 10.0– 13.4 µm (n=47), with rostrate ends. Raphe sternum straight and narrow, central area slightly expanded, formed by 5–6 irregularly shortened median striae on either side of the raphe, 1–3 (usually 2) rounded isolated pores on one side of the central area. Central pores more expanded internally, located on the prominent central nodule. Raphe straight with proximal ends externally slightly expanded, rounded and internally deflected to the side of central pores; distal ends turned into opposite directions and each one with distinct morphology, hooked-like at one end of the valve and gradually curved at the other. Internally, the distal raphe ends terminate in small helictoglossae. Striae radiate, arched in the middle portion of valve, becoming parallel to convergent at the apices, 17–21 in 10 µm, extending onto the valve mantle, formed by one row of rounded to elliptical areolae, 36–39 in 10 µm. Etymology: —This species is named in honor of Dr. Ita Moema Valente-Moreira, a retired diatom researcher from Universidade Federal do Paraná.
 Ecological data:— The collected sample from Papagaios river showed high temperature (22.5ºC), slightly acid conditions (pH 6.7), 102.8 µS.cm -1 of conductivity and 1.52 mg /L of dissolved oxygen (Visinoni 2002).

description: Since the existing calculations of the effective meson mass in nuclear medium involve approximations, it is important to examine whether they satisfy the general requirement of the equivalence theorem that the physical observables should be independent of the choice of field variables. We study here consequences of nucleon field transformations. As an illustrative case we consider the in-medium effective pion mass calculated for the s-wave pion-nucleon interaction in the linear density approximation. We demonstrate that it is necessary to include the Born term explicitly in order that the effective pion mass should obey the equivalence theorem.

Gaugino Condensation in Heterotic Fivebrane Background

description: The gaugino propagator is calculated by explicitly considering the propagation of a heterotic string between two different points in space-time using the non-trivial world-sheet conformal field theory for the fivebrane background. We find that there are no propagations of gaugino which is in the spinor representation of the non-trivial four-dimensional space of the fivebrane background. This result is consistent with the arguments on the fermion zero-modes of the fivebrane background in the low-energy heterotic supergravity theory. Furthermore, assuming the continuous limit to the flat space-time background at the place far away from the fivebrane, we suggest an effective propagator which is effective only at the place far away from the fivebrane in the flat space-time limit. From the effective propagator we evaluate a possible gaugino pair condensation. The result is consistent with the suggested scenario of the gaugino condensation in the fivebrane background in the low-energy heterotic supergravity theory.

description: Population growth has reduced the available freshwater resources and increased water pollution, leading to a severe global freshwater crisis. The decontamination and reuse of wastewater is often proposed as a solution for water scarcity worldwide. Membrane technology is a promising solution to the problems currently facing the water and wastewater treatment industry. However, another problem is the high energy costs required to operate systems which use membranes for water treatment. In addition, membranes need to be replaced frequently due to fouling and biofouling, which negatively affect water flow through the membranes. To address these problems, the researchers proposed membrane modification as a solution. One of the exciting applications of plasmonic nanoparticles (NPs) is that they can be used to modify the surface of membranes to yield various properties. Positive feedback was reported on plasmonic-modified membranes as means of wastewater treatment. However, a fundamental gap exists in studies of plasmonic membranes’ performance and applications. Given the importance of membrane technology for water and wastewater treatment, this paper reviews recent advances in the development of plasmonic chemically modified bioactive membranes and provides a perspective for future researchers interested in investigating modified membranes.

description: The origin and evolution of isotopes of the lightest elements H2, He3, Li, Be, B in the universe is a key problem in such fields as astrophysics of CR, Galactic evolution, non-thermal nucleosynthesis, and cosmological studies. One of the major sources of these species is spallation by CR nuclei in the interstellar medium. On the other hand, it is the B/C ratio in CR and Be10 abundance which are used to fix the propagation parameters and thus the spallation rate. We study the production and Galactic propagation of isotopes of elements Z<6 using the numerical propagation code GALPROP and updated production cross sections.

description: Using official data from the farm structure surveys 2010 and 2016 for roughly 10,000 German farms specialised on arable farming we analyse the effects of structural change on participation in agri-environmental programmes by estimation of a multinomial logit model. Large farms participating in 2010 tend more often than smaller farms to stop participation by 2016. However, farm growth steps increase the probability to continue or start with participation in 2016. Younger farmers are more likely to participate than older farmers, unless the latter are sure to have a successor. Farms on which generational renewal took place between 2010 and 2016 show statistically significant increases in the probability to continue or start with agri-environmental commitments.

description: Mass emergencies increasingly pose significant threats to human life, with a disproportionate burden being incurred by older adults. Research has explored how mobile technology can mitigate the effects of mass emergencies. However, less work has examined how mobile technologies support older adults during emergencies, considering their unique needs. To address this research gap, we interviewed 16 older adults who had recent experience with an emergency evacuation to understand the perceived value of using mobile technology during emergencies. We found that there was a lack of awareness and engagement with existing crisis apps. Our findings characterize the ways in which our participants did and did not feel crisis informatics tools address human values, including basic needs and esteem needs. We contribute an understanding of how older adults used mobile technology during emergencies and their perspectives on how well such tools address human values.

description: Significant events such as volcanic eruptions can have global and long lasting impacts on climate. These global impacts, however, are not uniform across space and time. Understanding how the Mt. Pinatubo eruption affects global and regional climate is of great interest for predicting impact on climate due to similar events. We propose a Bayesian framework to simultaneously detect and estimate spatially-varying temporal changepoints for regional climate impacts. Our approach takes into account the diffusing nature of the changes caused by the volcanic eruption and leverages spatial correlation. We illustrate our method on simulated datasets and compare it with an existing changepoint detection method. Finally, we apply our method on monthly stratospheric aerosol optical depth and surface temperature data from 1985 to 1995 to detect and estimate changepoints following the 1991 Mt. Pinatubo eruption.

description: Cofiltered diagrams of spectra, also called pro-spectra, have arisen in diverse areas, and to date have been treated in an ad hoc manner. The purpose of this paper is to systematically develop a homotopy theory of pro-spectra and to study its relation to the usual homotopy theory of spectra, as a foundation for future applications. The surprising result we find is that our homotopy theory of pro-spectra is Quillen equivalent to the opposite of the homotopy theory of spectra. This provides a convenient duality theory for all spectra, extending the classical notion of Spanier-Whitehead duality which works well only for finite spectra. Roughly speaking, the new duality functor takes a spectrum to the cofiltered diagram of the Spanier-Whitehead duals of its finite subcomplexes. In the other direction, the duality functor takes a cofiltered diagram of spectra to the filtered colimit of the Spanier-Whitehead duals of the spectra in the diagram. We prove the equivalence of homotopy theories by showing that both are equivalent to the category of ind-spectra (filtered diagrams of spectra). To construct our new homotopy theories, we prove a general existence theorem for colocalization model structures generalizing known results for cofibrantly generated model categories.
