description: The difficulty of processing gigapixel whole slide images (WSIs) in clinical microscopy has been a long-standing barrier to implementing computer aided diagnostic systems. Since modern computing resources are unable to perform computations at this extremely large scale, current state of the art methods utilize patch-based processing to preserve the resolution of WSIs. However, these methods are often resource intensive and make significant compromises on processing time. In this paper, we demonstrate that conventional patch-based processing is redundant for certain WSI classification tasks where high resolution is only required in a minority of cases. This reflects what is observed in clinical practice; where a pathologist may screen slides using a low power objective and only switch to a high power in cases where they are uncertain about their findings. To eliminate these redundancies, we propose a method for the selective use of high resolution processing based on the confidence of predictions on downscaled WSIs --- we call this the Selective Objective Switch (SOS). Our method is validated on a novel dataset of 684 Liver-Kidney-Stomach immunofluorescence WSIs routinely used in the investigation of autoimmune liver disease. By limiting high resolution processing to cases which cannot be classified confidently at low resolution, we maintain the accuracy of patch-level analysis whilst reducing the inference time by a factor of 7.74.

description: We use Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS) longslit low-resolution spectroscopy from 1150A to 10,300A to study the physical conditions in the narrow-line region (NLR) of the Seyfert 2 galaxy Markarian 3. We find from the HeII 1640/4686 line ratio and the Balmer decrement that the extinction within Markarian 3 along the line-of-sight to the NLR is best characterized by a Large Magellanic Cloud (LMC) type extinction curve. We observe an extinction gradient increasing from west to east along the STIS slit in both line and continuum emission. We infer from this gradient that the host galaxy disk is tilted towards the observer in the east: the line-of-sight to the eastern emission-line cone intersects more dust in the plane of the galaxy than that to the western cone. We model the observed continuum as a combination of reddened host galaxy light from an old stellar population, reddened H+ and He++ recombination continua, and less reddened scattered light from the central engine with spectral index alpha=1 (L(nu) proportional to nu^(-alpha)). The host galaxy to scattered-light ratio is estimated to be 3:1 at 8125 A in 0.1 X 1.8 square-arcsecond aperture. We estimate that the amount of intrinsic non-ionizing UV continuum scattered into our line-of-sight is 0.04%. This is consistent with our estimate of the scattering fraction for broad CIV 1548,1551 emission.

title: Management Consultancy As Practice: A Study Of The Duality Of The Management Consultants' Role
Creators: name: Hartley, Jeanette
Publisher: name: The Open University
Year: 2017

description: The central question addressed in this research is: “How do practicing management consultants cope with the duality of their role?” Management consultants are often responsible for internal business leadership roles as well as developing business, people and knowledge alongside client delivery (Richter et al., 2008). The research sought to understand the nature of the potentially conflicting demands of their client-facing and consultancy-facing roles on management consultants, how conflicts arise and how they are managed. The substantive aim was to build on and extend existing studies of duality and bring a new perspective to academic knowledge relating to management consultancy. Data collection was through semi-structured interviews, observations and a limited number of documents. Grounded analysis was used to construct the data and develop a framework linking data categories and themes to existing theory. The research found that the main conflict between the consultancy-facing and client-facing demands on management consultants centred on the requirement for the physical presence of the management consultant and the incompatibility of performing consultancy related tasks on client site. Management consultants managed the conflict by performing consultancy related tasks in the evenings at weekends as far as possible. This resulted in further conflicts with achieving a work-life balance and the demands of family. The research focused on a practice within a single mainstream global consultancy and findings cannot therefore be generalised to other management consultancies (Tsang, 2014). However, the findings may provide the basis for further research across a range of management consultancies (Kanter, 1977 cited in Bryman and Bell, 2015).

description: Here we revisit the thermodynamics of the Kitaev quantum spin liquid realized on the honeycomb lattice. We address two main questions: First, we investigate whether there are observable thermodynamic signatures of the topological Majorana boundary modes of the Kitaev honeycomb model. We argue that for the time-reversal invariant case the residual low-temperature entropy is the primary thermodynamic signature of these Majorana edge modes, and verify using large-scale Monte Carlo simulations that this residual entropy is present in the full Kitaev model. When time-reversal symmetry is broken, the Majorana edge modes are potentially observable in more direct thermodynamic measurements such as the specific heat, though only at temperatures well below the bulk gap. % Second, we study the energetics, and the corresponding thermodynamic signatures, of the flux excitations in the Kitaev model. Specifically, we study the flux interactions on both cylinder and torus geometries numerically, and quantify their impact on the thermodynamics of the Kitaev spin liquid by using a polynomial fit for the average flux energy as a function of flux density and extrapolating it to the thermodynamic limit. By comparing this model to Monte Carlo simulations, we find that flux interactions have a significant quantitative impact on the shape and the position of the low-temperature peak in the specific heat.

description: The article provides brief reflections on the real and financial division of labor at the local level, with particular reference to Italy’s dualistic situation. The starting point is the finding of a large and persistent territorial divarication, across large subnational areas, between savings and investment. Important implications are drawn for the Italian financial structure, which has a decisive role in the processes of finance and adjustment of real imbalances not only among operators in surplus and deficit - something commonly taken into account - but also between regions. In this context, it is certainly relevant to ask whether the dualism in levels of development between the South and the rest of the country coexists and interacts with a corresponding financial dualism. Furthermore, how does the territorial distribution of productive activities and of the financial structure evolve? The author addresses these central questions. JEL Codes: O16, O52

description: Discovering and isolating infected individuals is a cornerstone of epidemic control. Because many infectious diseases spread through close contacts, contact tracing is a key tool for case discovery and control. However, although contact tracing has been performed widely, the mathematical understanding of contact tracing has not been fully established and it has not been clearly understood what determines the efficacy of contact tracing. Here, we reveal that, compared with "forward" tracing---tracing to whom disease spreads, "backward" tracing---tracing from whom disease spreads---is profoundly more effective. The effectiveness of backward tracing is due to simple but overlooked biases arising from the heterogeneity in contacts. Using simulations on both synthetic and high-resolution empirical contact datasets, we show that even at a small probability of detecting infected individuals, strategically executed contact tracing can prevent a significant fraction of further transmissions. We also show that---in terms of the number of prevented transmissions per isolation---case isolation combined with a small amount of contact tracing is more efficient than case isolation alone. By demonstrating that backward contact tracing is highly effective at discovering super-spreading events, we argue that the potential effectiveness of contact tracing has been underestimated. Therefore, there is a critical need for revisiting current contact tracing strategies so that they leverage all forms of biases. Our results also have important consequences for digital contact tracing because it will be crucial to incorporate the capability for backward and deep tracing while adhering to the privacy-preserving requirements of these new platforms.

description: We investigate the effects of lateral interactions on the conductance of two molecules connected in parallel to semi-infinite leads. The method we use combines a Green function approach to quantum transport with density functional theory for the electronic properties. The system, modeled after a self-assembled monolayer, consists of benzylmercaptane molecules sandwiched between gold electrodes. We find that the conductance increases when intermolecular interaction comes into play. The source of this increase is the indirect interaction through the gold substrate rather than direct molecule-molecule interaction. A striking resonance is produced only 0.3 eV above the Fermi energy.

description: We have detected likely z~7-8 galaxies in the 144"x144" NICMOS observations of the Hubble Ultra Deep Field. Objects are required to be >3 sigma detections in both NICMOS bands, J and H. The selection criteria for this sample are (z-J)>0.8, (z-J) > 0.66 (J-H)+0.8, (J-H)<1.2, and no detection at <8500 Angstroms. The 5 selected sources have total magnitudes H~27. Four of the five sources are quite blue compared to typical lower-redshift dropout galaxies and are clustered within a 1 arcmin**2 region. Because all 5 sources are near the limit of the NICMOS data, we have carefully evaluated their reality. Each of the candidates is visible in different splits of the data and a median stack. We analyzed several noise images and estimate the number of spurious sources to be 1+/-1. A search using an independent reduction of this same data set clearly revealed 3 of the 5 candidates and weakly detected a 4th candidate, suggesting the contamination could be higher. For comparison with predictions from lower redshift samples we take a conservative approach and adopt four z~7-8 galaxies as our sample. With the same detection criteria on simulated datasets, assuming no-evolution from z~3.8, we predict 10 sources at z~7-8, or 14 if we use a more realistic (1+z)^{-1} size scaling. We estimate that the rest-frame continuum UV (~1800 Angstroms) luminosity density at z~7.5 (integrated down to 0.3L*) is just 0.20_{-0.08}^{+0.12}x that found at z~3.8. Effectively this sets an upper limit on the luminosity density down to 0.3 L*. This result is consistent with significant evolution at the bright end of the luminosity function from z~7.5 to z~3.8. Even with the lower UV luminosity density at z~7.5, it appears that galaxies could still play an important role in reionization at these redshifts, though definitive measurements remain to be made.

description: Competitive interactions significantly impact plant diversity, playing a crucial role in community assembly. This study, conducted in the evergreen broadleaved forest of Bidoup-Nui Ba National Park in southern Vietnam, aimed to investigate neighborhood competition and spatial patterns of tree species. In 2024, a 4-ha study plot was established within the strictly protected zone of the national park for data collection purposes. A total of 7,666 trees with a diameter at breast height (DBH) ≥2.5 cm, representing sixty-six species from thirty-one families, were identified, measured for DBH, and mapped for stem location. Unmarked and marked point-pattern analyses were employed to examine the spatial patterns of the most abundant species. The results revealed that the fifteen most abundant species exhibited an aggregated distribution at small scales (0-30 m), with their spatial patterns correlating with their life-history stages. Specifically, the spatial arrangements shifted from aggregation during the juvenile stage to randomness or regularity at the subadult and adult stages. Intra- and interspecific competition were found to be closely tied to spatial scale, showcasing instances of both symmetric and asymmetric competition. Notably, interspecific associations mainly exhibited spatial independence, especially at 0-50 m scales. This study identified several vital ecological processes governing the spatial distribution and neighborhood competition among broadleaved tree species in the study area, including dispersal limitations, symmetric and asymmetric competition, and self-thinning of tree species.
title: Sharing Leadership in Top Teams: A Qualitative Case Study of One Governing Board in the Nonprofit Sector
Creators: name: Wilson-Jones, Lindsay
Publisher: name: The Open University
Year: 2017

description: Shared leadership is increasingly important in organisations today in order to meet the needs of changing environments, complex problems and to accommodate transparency and accountability. This is especially applicable to nonprofit organisations (NPOs) where good governance has been a concern for years not only because of underdeveloped theories of nonprofit governance (Cornforth, 2012) but also public pressure to demonstrate accountability, after reported cases of failed governance. This research has a qualitative exploratory methodological design that interprets emerging data to develop and clarify concepts. The thesis adopts an ontological relativist position towards the epistemology of constructionism, and employs an intepretivist methodology to discuss findings and concepts. The case study employs the concept of shared leadership, a mutual influence process in teams, (Pearce and Conger, 2003) and an ‘ethical form of board leadership’ for corporate boards following poor governance and various scandals (Vandewaerde et al, 2011, p.404) to explore sharing leadership and governance in one nonprofit board in practice. Three data collection techniques namely interviews, observation and document review have been carried out. Specifically, eight interviews, observation of one annual general meeting and one routine board meeting, and a review of 21 documents including seven board minutes and eight reports. The participants richly described their experiences, having been identified using a Braun and Clarke (2006) interpretive process that examines the following themes; compliance; core purpose; expert knowledge and leadership. Findings inductively identified from the data suggest support for the concept of co-leadership between two individuals; for board governance moving towards a pluralist perspective in 2017; and changing context as the locus of leadership during 2014 – 2017.

description: The cosmic distance duality relation (CDDR), $D_{\rm L}(1+z)^{-2}/D_{\rm A}=η=1$, with $D_{\rm L}$ and $D_{\rm A}$, being the luminosity and angular diameter distances, respectively, is a crucial premise in cosmological scenarios. Many investigations try to test CDDR through observational approaches, even some of these ones also consider a deformed CDDR, i.e., $η=η(z)$. In this paper, we use type Ia supernovae luminosity distances and galaxy cluster measurements (their angular diameter distances and gas mass fractions) in order to perform a Bayesian model comparison between $ η(z) $ functions. We show that the data here used are unable to pinpoint, with a high degree of Bayesian evidence, which $η(z)$ function best captures the evolution of CDDR.

More-than-human political geographies : abjection and sovereign power

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2023
Subjects: subject: 501

description: This article unravels the processes of abjection that render certain nonhumans as abject, devoid of value and amenable to elimination and killing. It argues that these processes play a constitutive role in practices of state-making and sovereign power. Abjection works towards the exclusion and rejection of certain parts of a supposed socio-material order, which, for one reason or another, confuse dominant categorizations, trespass certain spatial boundaries or challenge socially produced distinctions and hierarchies (Bataille, 1970 [1934]; Kristeva, 1982). Abjected nonhumans thus regularly become the target of state-induced practices of elimination and culling – as is the case, for instance, with species classified as ‘invasive’, as ‘pests’, as ‘biosecurity threat’ or as ‘disease reservoirs’. Yet, abjection also points to the ability of nonhumans to unsettle, challenge and confuse dominant boundaries and established orders. Abject beings inhabit “unruly edges” (Tsing, 2012) from which they challenge and transcend sovereign impulses to order, govern and eliminate their existence. Taking cue from previous works on abjection and sovereign power, on the one hand, and works on the role of nonhumans in political processes, on the other, I argue that abjection and state-making are not only intertwined but also crucially played out in relation to nonhuman forms of life and death. My wider conceptual aim is to illustrate what an engagement with processes of abjection has to offer for the agenda of more-than-human political geographies.

description: Around 200,000 yr ago, Homo sapiens emerged in Africa. By 40ka, Homo sapiens had spread throughout Eurasia, and a major competingspecies, the Neanderthals, became extinct. The factors thatdrove our species “out of Africa” remain a topic of vigorous debate.Existing research invokes climate change as either providing opportunitiesor imposing limits on human migration. Yet the paleoclimatehistory of northeast Africa, the gateway to migration, is unknown.Here, we reconstruct temperature and aridity in the Horn of Africaregion spanning the past 200,000 yr. Our data suggest that warmand wet conditions from 120,000 to 90,000 yr ago could have facilitatedearly waves of human migration toward the Levant and Arabia,as supported by fossil and lithic evidence. However, the primaryout-of-Africa event, as constrained by genetic studies (ca. 65–55 ka),occurred during a cold and dry time. This complicates the climatemigrationrelationship, suggesting that both “push” and “pull” factorsmay have prompted Homo sapiens to colonize Eurasia.
Statistical Physics of Rupture in Heterogeneous Media

description: The damage and fracture of materials are technologically of enormous interest due to their economic and human cost. They cover a wide range of phenomena like e.g. cracking of glass, aging of concrete, the failure of fiber networks in the formation of paper and the breaking of a metal bar subject to an external load. Failure of composite systems is of utmost importance in naval, aeronautics and space industry. By the term composite, we refer to materials with heterogeneous microscopic structures and also to assemblages of macroscopic elements forming a super-structure. Chemical and nuclear plants suffer from cracking due to corrosion either of chemical or radioactive origin, aided by thermal and/or mechanical stress. Despite the large amount of experimental data and the considerable effort that has been undertaken by material scientists, many questions about fracture have not been answered yet. There is no comprehensive understanding of rupture phenomena but only a partial classification in restricted and relatively simple situations. This lack of fundamental understanding is indeed reflected in the absence of reliable prediction methods for rupture, based on a suitable monitoring of the stressed system. Not only is there a lack of non-empirical understanding of the reliability of a system, but also the empirical laws themselves have often limited value. The difficulties stem from the complex interplay between heterogeneities and modes of damage and the possible existence of a hierarchy of characteristic scales (static and dynamic). The paper presents a review of recent efforts from the statistical physics community to address these points.

description: Mean-field evolution equations for the exciton and photon populations and polarizations (Bloch-Lamb equations) are written and numerically solved in order to describe the dynamics of electronic states in a quantum dot coupled to the photon field of a microcavity. The equations account for phase space filling effects and Coulomb interactions among carriers, and include also (in a phenomenological way) incoherent pumping of the quantum dot, photon losses through the microcavity mirrors, and electron-hole population decay due to spontaneous emission of the dot. When the dot may support more than one electron-hole pair, asymptotic oscillatory states, with periods between 0.5 and 1.5 ps, are found almost for any values of the system parameters.

description: Handwritten Arabic character recognition systems face several challenges, including the unlimited variation in human handwriting and large public databases. In this work, we model a deep learning architecture that can be effectively apply to recognizing Arabic handwritten characters. A Convolutional Neural Network (CNN) is a special type of feed-forward multilayer trained in supervised mode. The CNN trained and tested our database that contain 16800 of handwritten Arabic characters. In this paper, the optimization methods implemented to increase the performance of CNN. Common machine learning methods usually apply a combination of feature extractor and trainable classifier. The use of CNN leads to significant improvements across different machine-learning classification algorithms. Our proposed CNN is giving an average 5.1% misclassification error on testing data

description: Magnetoelectric (NiFe2O4)0.3−(Sr0.5Ba0.5Nb2O6)0.7 composites with addition of LiNbO3 as sintering additive were prepared by a classical mixed-oxide method. XRD patterns of ceramics sintered between 1000 and 1200 °C show the desired Sr0.5Ba0.5Nb2O6 and NiFe2O4 phases. SEM investigations confirm the 0–3 connectivity of the composite ceramics. The addition of 10 and 20 mol% LiNbO3 improves the densification of the composite ceramics and leads to an increase of the size of the Sr0.5Ba0.5Nb2O6 grains. Magnetic measurements show hystereses with low coercivities. Dielectric measurements were carried out depending on temperature and frequency. The samples with the LiNbO3 addition show significantly higher resistivity values (σDC). Magnetoelectric measurements were carried out in dependence of the magnetic DC-field, temperature, and frequency. The maximum magnetoelectric coefficient (αME) rises with the addition of LiNbO3 from 180 to 803 µV Oe−1 cm−1 (@900 Hz). Temperature dependent measurements show a continuously decreasing of αME with lower temperature.

description: Using the exclusive decay B^0_s -> J/psi (mu+mu-) phi(K+K-), we report the most precise single measurement of the B^0_s lifetime. The data sample corresponds to an integrated luminosity of approximately 220 pb-1 collected with the DO detector at the Fermilab Tevatron Collider in 2002-2004. We reconstruct 337 signal candidates, from which we extract the B^0_s lifetime, τ(B^0_s) = 1.444 +0.098/-0.090 stat +/- 0.020 sys ps. We also report a measurement for the lifetime of the B^0 meson using the exclusive decay B^0 -> J/psi (mu+mu-)K*0(892)(K+pi-). We reconstruct 1370 signal candidates, obtaining τ(B^0) = 1.473 +0.052/-0.050 stat +/- 0.023 sys ps, and the ratio of lifetimes, τ(B^0_s)/τ(B^0) = 0.980 +0.076/-0.071 stat +/- 0.003 sys.

Investigating Quantum Approximate Optimization Algorithms under Bang-bang Protocols

description: The quantum approximate optimization algorithm (QAOA) is widely seen as a possible usage of noisy intermediate-scale quantum (NISQ) devices. We analyze the algorithm as a bang-bang protocol with fixed total time and a randomized greedy optimization scheme. We investigate the performance of bang-bang QAOA on MAX-2-SAT, finding the appearance of phase transitions with respect to the total time. As the total time increases, the optimal bang-bang protocol experiences a number of jumps and plateaus in performance, which match up with an increasing number of switches in the standard QAOA formulation. At large times, it becomes more difficult to find a globally optimal bang-bang protocol and performances suffer. We also investigate the effects of changing the initial conditions of the randomized optimization algorithm and see that better local optima can be found by using an adiabatic initialization.

Measuring Topological Chaos

description: The orbits of fluid particles in two dimensions effectively act as topological obstacles to material lines. A spacetime plot of the orbits of such particles can be regarded as a braid whose properties reflect the underlying dynamics. For a chaotic flow, the braid generated by the motion of three or more fluid particles is computed. A ``braiding exponent'' is then defined to characterize the complexity of the braid. This exponent is proportional to the usual Lyapunov exponent of the flow, associated with separation of nearby trajectories. Measuring chaos in this manner has several advantages, especially from the experimental viewpoint, since neither nearby trajectories nor derivatives of the velocity field are needed.

La transizione delle economie di tipo post-sovietico: sviluppi previsti e imprevisti

Subjects: subject: Post-Soviet transition
subject: P20, P26

description: The transition of former Soviet-type countries has spawned a growing literature with debates taking shape on “shock therapy” versus the gradualist approach, the sequencing of transition measures, choice of privatisation methods, etc. The present work looks at what is missing in this avalanche of articles and papers: an attempt at stock-taking. The author looks at theorists’ concerns from two different angles: first, whether certain developments expected by theorists did or did not happen and, second, whether certain developments that happened were expected by theorists. One of the most important insights provided is that only a small part of theorists’ expectations about problems of transition did, in fact, materialise in an manner expected by theory.

description: This paper connects different business cultures of large banks in various countries of the EMU with monetary policy issue of the ECB. First, the banks' competitive potential as well as their strategic behaviour is outlined. Furthermore, a cluster analysis exhibits some banking groups according to the liability-orientation of the largest EMU-banks, and a factor analysis gives some additional information about their asset-orientation; both business-orientations play an important role for the efficiency of monetary policy. Finally, the different cash requirements within the various European coun-tries might lead to totally new bank strategies, yielding to an internationali-sation of large bank-credits. JEL: F15, G21

title: Exploring the Subjective Experience of Everyday Surveillance: The Case of Smartphone Devices as Means of Facilitating "Seductive" Surveillance
Creators: name: Troullinou, Pinelopi
Publisher: name: The Open University

description: In western societies, the dependence on Information and Communication technologies (ICTs) is rapidly increasing. Smartphones, in particular, seem to be the most popular digital devices as they are an all-in-one digital gadget that due to Internet connection serves a wide range of purposes. However, in the context of neoliberal capitalism where the traditionally distinct spheres of security and marketing have merged, data generated through these personal devices can also be used for state and market purposes raising serious societal concerns. The present study contributes to the call for the understanding of the subjective experience of everyday surveillance operating through personal digital devices. Focusing on smartphones as a consumption product, the study draws mainly upon design technology and consumer research literature to suggest the theoretical framework of seductive surveillance in order to shed light on the reasons why individuals ‘willingly’ participate to their surveillance. The discourse analysis of thirteen focus groups - conducted amongst students in British universities - and follow up emails showed that participants have developed a dependent relationship with their smartphones based on notions of security, gamification, immediacy and neophilia. These discursive patterns reveal participants’ seduction to smartphones and consequently to surveillance. This seduced position sheds light on the three ‘resistant’/power diagnostic discourses emanating from the analysis: resignation, avoidance and responsibilization, all being negotiation strategies with surveillance as form of power which unfold in different ways and enabled the person to remain seduced. Surveillance met different resistance, as power diagnostic discourse, depending on the acknowledgement of the ‘face’ of the surveillant Other. These findings have theoretical and practical implications. A methodological contribution is also made using visual vignettes to raise discussion on the issue in question.
