description: In September 2023, the two largest bioimaging networks in the Americas, Latin America Bioimaging (LABI) and BioImaging North America (BINA), came together during a 1-week meeting in Mexico. This meeting provided opportunities for participants to interact closely with decision-makers from imaging core facilities across the Americas. The meeting was held in a hybrid format and attended in-person by imaging scientists from across the Americas, including Canada, the United States, Mexico, Colombia, Peru, Argentina, Chile, Brazil and Uruguay. The aims of the meeting were to discuss progress achieved over the past year, to foster networking and collaborative efforts among members of both communities, to bring together key members of the international imaging community to promote the exchange of experience and expertise, to engage with industry partners, and to establish future directions within each individual network, as well as common goals. This meeting report summarises the discussions exchanged, the achievements shared, and the goals set during the LABIxBINA2023: Bioimaging across the Americas meeting.
title: Microscopic Optical Trapping of Ultracold Neutral Atoms for Applications in Quantum Information
Creators: name: Copley-May, Michael
Publisher: name: The Open University
Year: 2019

description: In this thesis, the development of an experimental system for microscopic dipole trapping of ultracold neutral rubidium atoms is presented. The purpose of this system is to advance towards the experimental realisation of a quantum computational protocol utilising neutral atoms as qubits. It is intended that the quantum gate operations between qubits will be implemented by a scheme using Rydberg blockade, imposing a restriction on the maximum size of the dipole-trapped atom cloud; the spatial extent of the atomic ensemble contained in this trap must be smaller than the blockade radius to ensure that one single collective Rydberg state per qubit can be achieved. Therefore the experiment was designed with the intent of fulfilling these challenging requirements.

 This project involved the design and construction of an improved ultra-high vacuum chamber containing the optical setup for the experiment, successfully achieving pressures below 5 x 10-10 mbar. A magneto-optical trap was produced to act as a background reservoir of atoms from which to load the dipole trap. Numerous experimental measurements were done to characterise the physical properties of the trapped atoms, including the number, density and temperature of atoms, as well as the lifetime of the trap. The results of these measurements led to the conclusion that a suitable reservoir for loading the dipole trap had been produced.

 Significant work was carried out to set up and obtain the dipole trap in the laboratory. Measurements of the characteristic properties of the trap and the atoms confined in the trap were carried out to investigate the behaviour of the atoms and to validate our design. Ultimately a trap containing tens of atoms was achieved, with an atom cloud diameter of ~1.2 µm in two dimensions, being well within the estimated Rydberg blockade radius of ~4.4 µm for n ~ 60 as intended. The two-photon excitation laser system for the probing of Rydberg states, for future applications in Rydberg blockade-based quantum gate operations, was also developed during the course of this work. Different Rydberg states were detected experimentally by the observation of Autler-Townes splitting in a three-level atom scheme.

 Overall, the work presented in this thesis provides a strong groundwork for the advancement towards neutral atom-based quantum gates, including the development of the experimental system and the production of standard procedures to carry out characterisation measurements of the traps efficiently in the future. The main achievements of this work are the establishment of the experimental apparatus, the achievement of a microscopic dipole trap which conforms to the requirements of an atomic qubit, and the significant growth in the knowledge of atom trapping specific to our system.

description: Africa’s population is expected to almost quadruple by 2100, from about 1.19 billion in 2015 to 4.39 billion. It will thus account for 39.12 per cent of the world’s population by 2100, against 16.14 per cent in 2015. The continent remains the most youthful globally, with a median age of 19.4 years compared to 29.6 globally, 29.2 for Latin America and the Caribbean (LAC) and 30.2 for Asia. Furthermore, more than 60 per cent of the continent’s population is below the age of 25 years, compared to around 42 per cent globally. While most other regions are experiencing population ageing, Africa is not. Therefore, the continent plays a significant role in global population dynamics due to its size, its youthful population and structure of the world’s population.

description: When dismantling nuclear facilities, surface decontamination of the premises must be carried out to ensure that the existing building structure is free of contamination. Typical nuclear power plants in Germany have 100,000 m2 to 450,000 m2 of a concrete surface, which must be decontaminated for successful clearance measurement. Usually, decontamination is carried out by removing the surface to the depth at which contamination is no longer present. Discussions with dismantling companies and nuclear power plant operators have shown that corner and inner edge decontamination in particular has so far been done with hand-held devices. Tools such as needle guns and grinding devices are state-of-the-art. These devices were originally used for renovation work and were therefore not specifically developed for the decontamination of buildings. In addition to the low performance of the devices, the uneven surface that is left behind, and the high physical strain on the workers, the lack of extraction also contributes to the limited suitability. The lack of extraction also comes with the use of additional industrial vacuum cleaners, which makes the already complex and tedious work even more time-consuming. In order to counteract these difficulties and problems and to provide an improved solution for the decontamination of corners and inner edges, the project "Ekont" is currently being realized. The aim of this project is to investigate the performance parameters of the currently used devices and to find ways to improve them. For this purpose, several demonstrators have already been developed and tested in a test setup. The aim of “EKONT-2” is to pursue the discovered potentials, not to leave the knowledge gained and the developed technology unused, and to carry out possible improvements so that an operational, trouble-free device can be developed. In order to achieve this goal, a research project limited to three years is to be started, in which the aspects of handling and the quality of the removal will be focused on and improved. The further development of the four existing prototypes, therefore, includes the following criteria: 
- Improvement of handling by weight reduction, reduction of external dimensions and revision of the edge guide 
- Improvement of the quality of the removal by an exact depth guidance and adjustable removal depth, surface 
suitable for clearance measurement, reduction of superfluous material and removal of surfaces with decontamination coatings 
- Improvement of occupational safety by reduction of dust exposure and eduction of vibrations and stress on the 
musculoskeletal system 
- Reduced time required for decontamination

description: This is the challenge design document for the "Diabetic Foot Ulcers Grand Challenge 2021" Challenge, accepted for MICCAI 2021. Diabetes is a global epidemic affecting approximately 425 million people. This figure is expected to rise to 629 million people by 2045 [1]. Diabetic Foot Ulcers (DFU) are a serious condition that frequently results from the disease. The rapid rise of the condition over the last few decades is a major challenge for healthcare systems around the world. Cases of DFU frequently lead to more serious conditions, such as infection and ischaemia, that can significantly prolong treatment, and often result in limb amputation, with more serious cases leading to death. In an effort to improve patient care and reduce the strain on healthcare systems, recent research has focussed on the creation of detection algorithms that could be used as part of a mobile app that patients could use themselves (or a carer/partner) to monitor their condition and to detect the appearance of DFU [2][3]. To this end, the collaborative work between Manchester Metropolitan University, Lancashire Teaching Hospital and the Manchester University NHS Foundation Trust has created an international repository of 6000 DFU images with labelled infection and ischaemia cases for the purpose of supporting research toward more advanced methods of DFU pathology recognition. With joint effort from the lead scientists of the UK, US, India and New Zealand, this challenge will solicit the original works in DFU, promote interactions between researchers and interdisciplinary collaborations.

Dynamically Influenced Molecular Clouds in the Nucleus of NGC 6946: Variations in the CO Isotopic Line Ratios

description: We present high resolution (~5'') maps of the J = 1 - 0 transitions of ^{13}CO and C^{18}O towards the nucleus of NGC 6946, made with the Owens Valley Millimeter Array. The images are compared with existing ^{12}CO(1-0) maps to investigate localized changes in gas properties across the nucleus. As compared to ^{12}CO, both ^{13}CO and C^{18}O are more confined to the central ring of molecular gas associated with the nuclear star formation; that is, ^{12}CO is stronger relative to ^{13}CO and C^{18}O away from the nucleus and along the spiral arms. The ^{12}CO(1-0)/^{13}CO(1-0) line ratio reaches very high values of >40. We attribute the relative ^{13}CO weakness to a rapid change in the interstellar medium from dense star forming cores in a central ring to diffuse, low density molecular gas in and behind the molecular arms. This change is abrupt, occurring in less than a beamsize (90 pc), about the size of a giant molecular cloud. Column densities determined from ^{13}CO(1-0), C^{18}O(1-0), and 1.4 mm dust continuum all indicate that the standard Galactic conversion factor, X_{CO}, overestimates the amount of molecular gas in NGC 6946 by factors of ~3-5 towards the central ring and potentially even more so in the diffuse gas away from the central starburst. We suggest that the nuclear bar acts to create coherent regions of molecular clouds with distinct and different physical conditions. The ^{12}CO(1-0)/^{13}CO(1-0) line ratio in galactic nuclei can be a signpost of a dynamically evolving ISM.

The Role of Protestant Missionaires in Mexico’s Indigenous Awakening

Publisher: name: Blackwell Publishing Ltd

Subjects: classificationCode: 5004
subject: Religious studies

description: Protestantism has grown rapidly among Latin America’s indigenous population since the 1980s. Despite Protestantism’s attractiveness to indigenous people, the literature has historically regarded it as incompatible with indigenous culture. Recent scholarship has moved beyond this assertion, focusing instead on the complexities of conversion and the paradoxes associated with it. Most scholars now argue that Protestantism can be compatible with indigenous culture. It is unclear, however, how Protestant institutions came to have a compatible relationship with indigenous culture. Indeed, Protestant churches/clergy continue to eschew many of the practices associated with indigenous culture. In this paper I address this question by examining the work of Protestant missionaries. I choose missionaries as my point of analysis because they were crucial in establishing Protestantism in the region, and thus the base point from which it is defined, practiced, and altered. As a case study I examine mission work in Oaxaca, Mexico. I argue that missionaries have changed both their conversion strategies and tactics for dealing with indigenous traditions. These changes make it easier for indigenous people to convert to Protestantism without rejecting key parts of their culture, and in a few cases by even embracing it. I examine two conversion strategies—group targeting and church planting. I also analyze three tactics missionaries use to negotiate indigenous customs considered ‘pagan.’ I choose tequio, village fiestas, and language politics because they have historically been sources of conflict between converts and their Catholic neighbours.

description: We demonstrate a novel type of spin Hall nano-oscillator (SHNO) that allows for efficient tuning of magnetic auto-oscillations over an extended range of gigahertz frequencies, using bipolar direct currents at constant magnetic fields. This is achieved by stacking two distinct ferromagnetic layers with a platinum interlayer. In this device, the orientation of the spin polarised electrons accumulated at the top and bottom interfaces of the platinum layer is switched upon changing the polarity of the direct current. As a result, the effective anti-damping required to drive large amplitude auto-oscillations can appear either at the top or bottom magnetic layer. Tuning of the auto-oscillation frequencies by several gigahertz can be obtained by combining two materials with sufficiently different saturation magnetization. Here we show that the combination of NiFe and CoFeB can result in 3 GHz shifts in the auto-oscillation frequencies. Bipolar SHNOs as such may bring enhanced synchronisation capabilities to neuromorphic computing applications.

description: Inequalities and poverty are important drivers of social exclusion, while conflict, social unrest and instability are its manifestation. The preponderance of conflicts in poor and unequal societies has long been documented in the literature.1 As Nagel succinctly argues, “political discontent and its consequences – protest, instability, violence, revolution – depend not only on the absolute level of economic well-being, but also on the distribution of wealth” (Nagel, 1974:453). According to the Kuznets’ inverted-U theory, a high level of income inequality radicalises the proletariat, enhances class polarisation and reduces the tolerance of the bourgeoisie for low-income group participation in political and decisionmaking processes (Muller, 1997).

description: We study the anisotropic Heisenberg (XYZ) spin-1/2 chain placed in a magnetic field pointing along the x-axis. We use bosonization and a renormalization group analysis to show that the model has a non-trivial fixed point at a certain value of the XY anisotropy a and the magnetic field h. Hence, there is a line of critical points in the (a,h) plane on which the system is gapless, even though the Hamiltonian has no continuous symmetry. The quantum critical line corresponds to a spin-flop transition; it separates two gapped phases in one of which the Z_2 symmetry of the Hamiltonian is broken. Our study has a bearing on one of the transitions of the axial next-nearest neighbor Ising (ANNNI) chain in a transverse magnetic field. We also discuss the properties of the model when the magnetic field is increased further, in particular, the disorder line on which the ground state is a direct product of single spin states.

description: The resounding economic growth of the past one and a halve decades and the bright prospects for the immediately future is changing the development landscape of Africa. Growth averaged 5.1 percent between 2000 and 2012 and doubled the continent’s average growth rate in the 1990s. The rapid growth path has started to change the narrative of Africa’s development from pessimism or a hopeless continent to an unprecedented optimism - an emerging growth pole and a vibrant frontier market. This emboldens many African countries to dream of “emerging” from the least and middle income developing countries groupings by aspiring to rapid and sturdy economic growth rates, large improvements in market and institutional efficiencies and also attracting large volumes of foreign direct investments (FDIs). The celebration of the 50 years anniversary of the African Union in 2013 rekindled this optimism which informed the preparation of the Common African Position on the post 2015 development agenda and the Agenda 2063. Why should Japan or any important partner be interested in Africa’s structural transformation? The implementation of the Tokyo International Conference on African Development’s (TICAD) initiative has shown Japan as a trusted development partner in the continent. This includes the $32.0 billion pledge in 2013 for the continent’s development in the next five years. While appreciating this very significant contribution, many reasons still abound for partners’ authorities and their private sectors to be fully engaged in Africa’s transformation agenda:

description: We show that a simple piecewise-linear system with time delay and periodic forcing gives rise to a rich bifurcation structure of torus bifurcations and Arnold tongues, as well as multistability across a significant portion of the parameter space. The simplicity of our model enables us to study the dynamical features analytically. Specifically, these features are explained in terms of border-collision bifurcations of an associated Poincaré map. Given that time delay and periodic forcing are common ingredients in mathematical models, this analysis provides widely applicable insight.

description: After 1989, price liberalization has established new relations in Slovak economy, and the problems of economic differentiation of agricultural companies seemed to disappear. However, economic results of our companies confirm the existence of this problem. In the pre-reform period, agricultural production intensity was considered the main factor of economic differentiation but the transformation of economy after 1990 has changed the methodological approach to business performance evaluation. The interest was shifted towards the value evaluation, comparing agricultural enterprises by economic/financial indicators. These methods enable to create quality classes and make a list of productivity. The work analyses the above problem in a group of agricultural enterprises in two regions of Slovakia. According to results of our analysis, an average company with the best performance is a limited liability company, farming up to 1000 ha of agricultural land in worse natural conditions (2ilina region).

title: The Long Pentraxin PTX3 as a Functional Ancestor of Antibodies in the Immune Response to Aspergillus Fumigatus
Creators: name: Parente, Raffaella
Publisher: name: The Open University
Year: 2019

description: Invasive aspergillosis (IA) is a life-threatening infection amongst immunocompromised individuals primarily caused by the opportunistic fungus Aspergillus fumigatus (AF). A key role in the early immune response to AF is played by the complement system, an essential component of the humoral arm of innate immunity that includes three distinct activation pathways: classical, lectin and alternative (CP, LP and AP, respectively). Other soluble pattern recognition molecules (PRMs) are known to cooperate with complement in the handling of AF, including collectins, ficolins and pentraxins. In particular, the long pentraxin PTX3 exerts non-redundant protective roles against AF. PTX3 is a functional ancestor of antibodies: it has opsonic activity towards AF, and enhances recognition, phagocytosis and killing of fungal conidia by immune cells, mainly polymorphonuclear neutrophils (PMNs), via complement and Fc receptors (FcRs) pathways. Ptx3-null mice are highly susceptible to IA and treatment with the exogenous protein has therapeutic efficacy in several models of IA in immunocompromised hosts. Furthermore, epidemiologic evidence indicates that variation in the ptx3 gene is associated with the risk of IA in human stem cell transplant recipients and invasive mold infections in acute leukemia patients. Here, I characterized the molecular mechanisms underlying the role of PTX3 in the opsono-phagocytosis and killing of AF conidia by human and murine PMNs, both in vitro and in vivo. I found that PTX3 promotes the selective recruitment of C3b on the wall of AF conidia, by exclusively targeting the AP of complement. Factor H (major inhibitor of the AP) is required for this process, thus pointing to a novel function (activating rather inhibitory) of this complement regulator when combined with PTX3. Also, complement receptor 1 (CR1, primary receptor of C3b), recognizes the PTX3-bound C3b on AF conidia and facilitates their uptake and killing by PMNs. Therefore, I identified a novel functional axis involving factor H, C3b and CR1 that supports the pro-phagocytic and pro-killing activities of PTX3 in antifungal immunity, and opens new vistas on the crosstalk between fundamental humoral components of the innate immune system.
An explanation for long flares from extragalactic globular cluster X-ray sources

description: Repeatedly flaring X-ray binaries have recently been discovered in NGC 4697 by Sivakoff and collaborators. We show that these flares can be explained as the result of eccentric binaries in globular clusters which accrete more rapidly at periastron than during the rest of the binary orbit. We show that theoretical timescales for producing eccentricities and circularising the binaries are consistent with what is needed to produce the observed population of flaring sources, although the circularisation timescales are highly uncertain on both observational and theoretical grounds. This model makes two clear theoretical predictions (1) the flares should be seen to be strictly periodic if adequate sampling is provided, and that periodicity should be of approximately 15 hours (2) this class of flaring behaviour should be seen only in globular cluster sources, and predominantly in the densest globular clusters. We also test the model for producing eccentricities through fly-by's of a third star near the binary in a globular cluster against a much larger database of millisecond pulsar observations than has been used in past work, and find that the theoretical cross sections for producing eccentricity in binaries are in reasonable agreement with most of the data, provided that the pulsar ages are about $4\times10^9$ years.

Bragg spectroscopy of discrete axial quasiparticle modes in a cigar-shaped degenerate Bose gas
Creators: name: Ghosh, Tarun Kanti
Publisher: name: arXiv
Year: 2004
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We propose an experiment in which long wavelength discrete axial quasiparticle modes can be imprinted in a 3D cigar-shaped Bose-Einstein condensate by using two-photon Bragg scattering experiments, similar to the experiment at the Weizmann Institute [J. Steinhauer {\em et al.}, Phys. Rev. Lett. {\bf 90}, 060404 (2003)] where short wavelength axial phonons with different number of radial modes have been observed. We provide values of the momentum, energy and time duration of the two-photon Bragg pulse and also the two-body interaction strength which are needed in the Bragg scattering experiments in order to observe the long wavelength discrete axial modes. These discrete axial modes can be observed when the system is dilute and the time duration of the Bragg pulse is long enough.

description: Basis Light-front Quantization (BLFQ) is a newly developed nonperturbative approach, aiming at solving relativistic bound systems based on the Hamiltonian formalism of light-front dynamics. In this work, we introduce its application to the positronium system at strong coupling, $α= 0.3$, with a dynamical photon mediating the interaction between the positron and the electron. Nonperturbative mass renormalization is needed to cancel the fermion self-energy divergence. Here, we present the resulting mass spectrum, light-front wave functions (LFWFs), and the photon distribution inside positronium.

description: We find the noise sensitivities (i.e., the quadratic terms of the energy with respect to the perturbation of the noise) of a particle shuttled by an optical lattice that moves according to a shortcut-to-adiabaticity transport protocol. Noises affecting different optical lattice parameters, trap depth, position, and lattice periodicity, are considered. We find generic expressions of the sensitivities for arbitrary noise spectra but focus on the white-noise limit as a basic reference, and on Ornstein-Uhlenbeck noise to account for the effect of non-zero correlation times.

Polarization and light curve variability: the "patchy shell" model
Creators: name: Nakar, Ehud
name: Oren, Yonatan
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent advances in early detection and detailed monitoring of GRB afterglows have revealed variability in some afterglow light curves. One of the leading models for this behavior is the patchy shell model. This model attributes the variability to random angular fluctuations in the relativistic jet energy. These an-axisymmetric fluctuations should also impose variations in the degree and angle of polarization that are correlated to the light curve variability. In this letter we present a solution of the light curve and polarization resulting from a given spectrum of energy fluctuations. We compare light curves produced using this solution to the variable light curve of GRB 021004 and we show that the main features in both the light curve and the polarization fluctuations are very well reproduced by this model. We use our results to draw constraints on the characteristics of the energy fluctuations that might have been present in GRB 021004.

Network Dynamics on Graphops

description: In this brief note, we report a formal mathematical observation: we are about to breach a major century-old barrier in the analysis of interacting particle systems. More precisely, it is well-known that in well-mixed/homogeneous/all-to-all-coupled systems, one may derive mean-field limit equations such as Vlasov-Fokker-Planck equations (VFPEs). A mesoscopic VFPE describes the probability of finding a single vertex/particle in a certain state, forming a bridge between microscopic statistical physics and macroscopic fluid-type approximations. One major obstacle in this framework is to incorporate complex network structures into limiting equations. In many cases, only heuristic approximations exist, or the limits rely on particular classes of integral operators. In this paper, we notice that there is a much more elegant, and profoundly more general, way available due to recent progress in the theory of graph limits. In particular, we show how one may easily enter complex network dynamics via graphops (graph operators) into VFPEs.

Trauma and Coloniality in Australian and Chilean women writers
Creators: name: Cidon, Melanie
Publisher: name: University of Southern Queensland
Year: 2024
Subjects: coloniality
Australian literature
Chilean literature

women writers

description: This project analyses the literary practices of women writers in Australia and Chile in order to further study the representation of trauma in postcolonial societies. Both countries share a comparable colonial past. The representation of trauma allows the comparison between two distinct geographic, linguistic and cultural areas which at the same time represent connections inherent in the Global South. The study of women’s writing in these contexts shines a light on silenced voices and marginalized narratives that contradict the postcolonial “Grand Narrative”. The reading of these women’s writing introduces the different types of violence experienced by characters whose voices remain unheard. The corpus also shines a light on intergenerational trauma that haunts the later generations who are unable to make sense of the obsessive thoughts and recurring overwhelming experiences they face. Thus, the research aims to expand our understanding of truth-telling in postcolonial societies. How can truth be told in a postcolonial context where truth is silenced and violence is normalized? The corpus reveals that this impossibility to tell leads the protagonists towards alternative ways to acknowledge their trauma. Without another’s assistance to understand and heal the past, fiction becomes a crucial mechanism to bring sense and coherence to fragmentary narratives. The project makes use of narrative analysis in conjunction with affective theories of trauma and (post)colonialism. The analysis of fiction gives a privileged insight into the characters’ minds and opens a window on non-conventional modes of beliefs. The research demonstrates how the protagonists engage with trauma through fiction. Storytelling and writing become essential processes of trauma narrative. It will be shown how the understanding of trauma requires the reconciliation of conventional and non-conventional modes of beliefs as well as the capacity of literature to inform our understanding of the functioning of trauma.
