description: I review some open questions relating to the large transverse momentum divergences in transverse moments of transverse momentum dependent (TMD) parton correlation func- tions. I also explain, in an abbreviated and summarized form, recent work that shows that the resulting violations of a commonly used integral relation are not perturbatively suppressed. I argue that this implies a need for more precise definitions for the correlation functions used to describe transverse moments.

title: Knowledge for development? : reflections from consultants and advisors in Bolivia
Creators: name: Borda-Rodriguez, Alexander
Publisher: name: The Open University
Year: 2008

description: Knowledge has been a central part of development discourses in the last 40 years. Development organisations have been concerned with its production and dissemination across developing countries with the purpose of eradicating poverty. This thesis focuses on the processes of knowledge production and dissemination for development in the work of consultants and advisors in two organisations in Bolivia. In particular, it examines and analyses the perceptions and reflections of consultants, advisors, and, to some extent, beneficiaries/clients; how they are framed by institutional and organisational discourses; and the apparent limits to reflexivity within the development assistance field. The thesis uses qualitative methods and draws on interview and documentary data collected in the east and central part of Bolivia. It examines the activities of consultants and advisors in two organisations: a Bolivian based development consultancy company Centro de Estudios y Proyectos (CEP) and a Dutch development agency (SNV). Using, as a conceptual framework, the notions of knowledge/power and discourse developed by Michel Foucault and aspects of Jürgen Habermas’s theory of communicative action, the thesis finds that knowledge engagements are heavily framed by dominant development discourses although they are potentially more productive when the different actors share meanings about the world. This, however, is not usually the case, and the engagements are marked by fundamental differences between the actors. The thesis also finds that consultants, advisors and beneficiaries/clients reflect, learn and hence produce rich knowledge individually but this is not openly shared with their organisational hierarchies because it can potentially challenge the development discourses that frame what the organisations do. The thesis concludes that, in order to overcome constraints imposed by dominant development discourses, it is necessary to build shared meanings between the actors where these do not exist, while recognising that their differences are also the source of new knowledge.

description: Mobile task automation is an emerging field that leverages AI to streamline and optimize the execution of routine tasks on mobile devices, thereby enhancing efficiency and productivity. Traditional methods, such as Programming By Demonstration (PBD), are limited due to their dependence on predefined tasks and susceptibility to app updates. Recent advancements have utilized the view hierarchy to collect UI information and employed Large Language Models (LLM) to enhance task automation. However, view hierarchies have accessibility issues and face potential problems like missing object descriptions or misaligned structures. This paper introduces VisionTasker, a two-stage framework combining vision-based UI understanding and LLM task planning, for mobile task automation in a step-by-step manner. VisionTasker firstly converts a UI screenshot into natural language interpretations using a vision-based UI understanding approach, eliminating the need for view hierarchies. Secondly, it adopts a step-by-step task planning method, presenting one interface at a time to the LLM. The LLM then identifies relevant elements within the interface and determines the next action, enhancing accuracy and practicality. Extensive experiments show that VisionTasker outperforms previous methods, providing effective UI representations across four datasets. Additionally, in automating 147 real-world tasks on an Android smartphone, VisionTasker demonstrates advantages over humans in tasks where humans show unfamiliarity and shows significant improvements when integrated with the PBD mechanism. VisionTasker is open-source and available at https://github.com/AkimotoAyako/VisionTasker.

description: Poly(ethylene oxide)-$\textit{b}$-poly(butylmethacrylate) (PEO-$\textit{b}$-PBMA) copolymers have recently been identified as excellent building blocks for the synthesis of hierarchical nanoporous materials. Nevertheless, while experiments have unveiled their potential to form bicontinuous phases and vesicles, a general picture of their phase and aggregation behavior is still missing. By performing Molecular Dynamics simulations, we here apply our recent coarse-grained model of PEO-$\textit{b}$-PBMA to investigate its self-assembly in water and tetrahydrofuran (THF) and unveil the occurrence of a wide spectrum of mesophases. In particular, we find that the morphological phase diagram of this ternary system incorporates bicontinuous and lamellar phases at high copolymer concentrations, and finite-size aggregates, such as dispersed sheets or disk-like aggregates, spherical vesicles and rod-like vesicles, at low copolymer concentrations. The morphology of these mesophases can be controlled by tuning the THF/water relative content, which has a striking effect on the kinetics of self-assembly as well as on the resulting equilibrium structures. Our results disclose the fascinating potential of PEO-$\textit{b}$-PBMA copolymers for the templated synthesis of nanostructured materials and offer a guideline to fine-tune their properties by accurately selecting the THF/water ratio.
title: A Pattern-Based Approach to Changing Software Requirements in Brown-Field Business Contexts
Creators: name: Brier, John
Publisher: name: The Open University
Year: 2011

description: In organisations, competitive advantage is increasingly reliant on the alignment of sociotechnical systems with business processes. 'Socio-technical' refers to the complex systems of people, tasks and technology. Supporting this alignment is exacerbated by the speed of technological change and its relationship with organisation growth. This complexity is further aggravated in a number of ways. Organisations and/or parts of organisations are structured differently and have different approaches to change. These differences impact on their responsiveness to change, their use of technology, and its relationship to business processes. In requirements engineering, a lack of understanding of the organisational context in which change takes place has been a problem over the last decade. Eliciting requirements is complex, with requirements changing constantly. Delivered change is affected by further changing needs, as stakeholders identify new ways of using IT. Changing requirements can lead to mismatches between tasks, technology and people. Relations and their alignment can be compromised. We contribute to understanding this complex domain by presenting an approach which engages with stakeholders/users in the early stages of the requirements elicitation process. The two expressions of the approach are derived from the literature and 19 real-world studies. They are referred to as Conceptual Framework and Change Frame. Both support a problem-centred focus on context analysis when reasoning about changing technology in business processes. The framework provides structures, techniques, notation and terminology. These represent, describe, and analyse the context in which change takes place, in the present and over time. The Change Frame combines an extension of the framework with an organisation pattern. It facilitates representing, describing and analysing change, across the strategic/operation area of an organisation. A known pattern of solution is provided, for the recurring change problem of representing an organisation-wide change in different organisation locations. Chapter 4 shows the conceptual framework in the context of a real-world study, and chapter 6 uses a real-world use/case scenario to illustrate the change frame. Both chapters show support for understanding change, through client/customer and stakeholder/users reasoning about the implications of change.

description: Liquid metal batteries (LMBs) are a promising grid-scale storage device however, the scalability of this technology and its electrochemical performance is limited by mass transport overpotentials. In this work, a numerical model of a three-layer LMB was developed using a multi-region approach. An alternative design concept for the battery aimed at reducing mass transport overpotentials, increasing cell capacity, and improving electrochemical cell performance was implemented and evaluated. The design consisted of a coil implanted in the cathode, which induced mixing in the layer. Four cases were compared: three in a 241 Ah LMB at 0.3, 0.5 and 1 A/cm$^{2}$, and one in a larger 481 Ah LMB at 0.5 A/cm$^{2}$. LMB performance was determined by comparison against baseline diffusion cases and a change in molar fraction of 0.1. The modified LMB exhibited dramatic performance increases with a 78% and 85% reduction in mass-transport overpotentials at 0.3 A/cm$^{2}$ and 0.5 A/cm$^{2}$, respectively. The improved performance of the battery was directly attributed to the flow generated in the cathode. It was found that the coil substantially increased the poloidal volumetric average velocity. Periodically, vortices formed that removed concentration gradients from the cathode-electrolyte interface, minimising concentration polarisation. The viability of the design was tested in a lab-scale prototype using Galinstan as the working fluid. The velocity of the flow was determined using particle image velocimetry (PIV), and the results compared to the numerical model. There was a close match between the experimental and numerical results, validating the numerical model and the viability of the design. Implementation of this design concept in future LMBs could lead to the realisation of extended discharge capacities and improved voltages. Future work is planned to test the coil in a working battery.

description: This study was conducted to validate and simulate the furnace exit gas temperature of oil fired boiler of power generating steam turbine unit of 323 MW after boiler modification and steam turbine retrofit. Furnace exit gas temperature is an important operational boiler parameter. Monitoring and controlling of furnace exit gas temperature is crucial to get reduction in fire side corrosion and fouling of furnace and furnace upstream heat transferring surfaces of boiler. Thermodynamic heat and mass balance model was applied to validate the furnace exit gas temperature measurement of newly installed Infrared meter at furnace exit. Furnace exit gas Temperature validation was performed at minimum and rated loading conditions of the boiler. The difference between measured and calculated furnace exit gas temperature was in the range of ± 20°C. Fifteen variables of boiler including steam turbine were selected at different operating conditions of the boiler to perform the simulation study of furnace exit gas temperature by using Excel statistical solver module. The temperature difference of measured and simulated temperature remained within ± 5°C at minimum and rated loading conditions of the boiler which is due to strong statistical co-relation among selected variables. Sensitivity of furnace exit gas temperature with respect to fuel mass flow at boiler rated loading condition was also performed by running furnace heat and mass balance model.

description: Strain engineering is used to obtain desirable materials properties in a range of modern technologies. Direct nanoscale measurement of the three-dimensional strain tensor field within these materials has however been limited by a lack of suitable experimental techniques and data analysis tools. Scanning electron diffraction has emerged as a powerful tool for obtaining two-dimensional maps of strain components perpendicular to the incident electron beam direction. Extension of this method to recover the full three-dimensional strain tensor field has been restricted though by the absence of a formal framework for tensor tomography using such data. Here, we show that it is possible to reconstruct the full non-symmetric strain tensor field as the solution to an ill-posed tensor tomography inverse problem. We then demonstrate the properties of this tomography problem both analytically and computationally, highlighting why incorporating precession to perform scanning precession electron diffraction may be important. We establish a general framework for non-symmetric tensor tomography and demonstrate computationally its applicability for achieving strain tomography with scanning precession electron diffraction data.
title: Supporting Student Nurses By The Educational Use of Self: A Hermeneutic Phenomenological Exploration of the Mentor Experience
Creators: name: Wilson, Anthea Maria Elisabeth
Publisher: name: The Open University
Year: 2012

description: This thesis reports on a study of the lived experience of clinical nurses as mentors of student nurses in the workplace. Pre-registration nurse education, in which students must spend fifty percent of their time in practice, relies on a partnership between universities and health care providers and, crucially, the availability of practice mentors, able to support and assess practice learning. Within a hermeneutic phenomenological research methodology, twelve nurses described their experiences of mentoring through conversational interviews and event diaries which included ‘rich pictures’. The mixed methods provided openings for participants to talk about the harder-to-access elements of experience and generated multiple layers of rich data. Analysis of the data involved the application of different interpretive lenses: existentials in the care structure of Heidegger’s (1962) Dasein and the four lifeworld existentials (van Manen, 1997). For these respondents, the mentoring experience was rewarding, satisfying, frustrating, and even distressing at times. Being a mentor meant existing in worlds of ‘high stakes’, ‘hope for the nursing profession’ and ‘fragments’, governed by resource constraints, contextual demands and concern for others. Educational purposes dominated their being, revealing an essence, interpretively coined as ‘the educational use of self’, which meant that they were individually and authentically engaged in supporting and assessing learning. This study promotes greater understanding of mentoring practice and workplace learning, which can inform processes of recruitment, preparation and support of both students and mentors. Key insights are that mentors need support to work with complex and often hidden knowledge, including situations involving their intuitions.

description: We consider a free boundary model of epithelial cell migration with logistic growth and nonlinear diffusion induced by mechanical interactions. Using numerical simulations, phase plane and perturbation analysis, we find and analyse travelling wave solutions with negative, zero, and positive wavespeeds. Unlike classical travelling wave solutions of reaction-diffusion equations, the travelling wave solutions that we explore have a well-defined front and are not associated with a heteroclinic orbit in the phase plane. We find leading order expressions for both the wavespeed and the density at the free boundary. Interestingly, whether the travelling wave solution invades or retreats depends only on whether the carrying capacity density corresponds to cells being in compression or extension.

description: The opto-electronic oscillators (OEOs) hosting self-sustained oscillations by a time-delayed mechanism are of particular interest in long-haul signal transmission and processing. On the other hand, owing to their unique tunability and compatibility, magnons—as elementary excitations of spin waves—are advantageous carriers for coherent signal transduction across different platforms. In this work, we integrated an opto-electronic oscillator with a magnonic oscillator consisting of a microwave waveguide and a yttrium iron garnet sphere. We find that, in the presence of the magnetic sphere, the oscillator power spectrum exhibits sidebands flanking the fundamental OEO modes. The measured waveguide transmission reveals anti-crossing gaps, a hallmark of the coupling between the opto-electronic oscillator modes and the Walker modes of the sphere. Experimental results are well reproduced by a coupled-mode theory that accounts for nonlinear magnetostrictive interactions mediated by the magnetic sphere. Leveraging the advanced fiber-optic technologies in opto-electronics, this work lays out a new, hybrid platform for investigating long-distance coupling and nonlinearity in coherent magnonic phenomena.

title: Turning Rough Dreams into a Polished Reality? Investigating the Formation of Human Capital in Botswana’s Diamond Cutting and Polishing Industry
Creators: name: Mbayi, Letsema
Publisher: name: The Open University
Year: 2013

description: This thesis investigates Botswana’s vision to become a downstream player in the global diamond industry by creating downstream capabilities that can continue to benefit the country when diamond mining is no longer profitable. Botswana is the largest producer of diamonds, accounting for a quarter of the world’s diamond production by value. The government has used diamond revenues to foster economic growth. The diamond-led growth has however resulted in a largely undiversified economy with limited job creation. Furthermore, the country’s diamond-led growth is not sustainable, with resource depletion expected to take place in the next two decades. In response to these economic challenges, the government used its supply dominance to force downstream linkages in the diamond industry. As a result the country has 21 diamond cutting and polishing firms that employ over 3000 workers, representing a tenth of employment in the manufacturing sector. The research examines how efficiently human capital formation in Botswana’s diamond cutting and polishing industry is taking place in order to create downstream capabilities that can foster the industry’s competitiveness. This is done by examining the role of the education and vocational training system, industry training institutes and the firms themselves in creating the human capital required in the diamond cutting and polishing industry. This research also considers the impact of technological change on the industry’s human capital requirements. The education and vocational training system was found to meet the industry’s basic general human capital requirements. But due to the 2embryotic institutional training in the industry, the firms were found to be making investments in both industry- and firm-specific human capital. The research argues that institutional industry training needs to be strengthened, particularly in light of technological changes that may result in more industry-specific human capital requirements in the Botswana’s diamond cutting and polishing industry.

description: A statistical study of the properties of molecular outflows is performed based on an up-to-date sample. 391 outflows were identified in published articles or preprints before February 28, 2003. The parameters of position, morphology, mass, energy, outflow dynamics and central source luminosity are presented for each outflow source. Outflow lobe polarity is known for all the sources, and 84% are found to be bipolar. The sources are divided into low mass and high mass groups according to either the available bolometric luminosity of the central source or the outflow mass.Energetic mass ejection may be a common aspect of the formation of high mass as well as low mass stars. Outflow masses are correlated strongly with bolometric luminosity of the center sources, which was obtained for the first time. There are also correlations between the central source luminosity and the parameters of mechanical luminosity and the thrust or force necessary to drive the outflow. The results show that flow mass, momentum and energy depend on the nature of the central source. Despite their similarity, there are differences between the high mass and low mass outflows on collimation, flow masses, mass-dynamical time relation and associated objects such as HH objects and water masers.Sources with characteristics of collapse or infall comprise 12% of the entire outflow sample. The spatial distribution of the outflow sources in the Galaxy is presented and the local occurrence rate is compared with the stellar birth rate.

The detailed research is conducted for the Croatian island -Goli Otok-. This island was used as a political prison camp in the period of 1948-1956. Today this place is completely abandoned, uninhabited and neglected, with the Croatian government having no clear view of how to preserve its memory or plan its future. The design project for -Goli Otok- will take into the account the features this space carries and act as a certain -thread- that will connect the current mental and physical condition asocciated with this island to its alternative futures.

description: Type II innate lymphoid cells (ILC2s) maintain homeostasis and barrier integrity in mucosal tissues. In both mice and humans, ILC2s poorly reconstitute after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Determining the mechanisms involved in their impaired reconstitution could improve transplant outcomes. By integrating single-cell chromatin and transcriptomic analyses of transplanted ILC2s, we identify a previously unreported population of converted ILC1-like cells in the mouse small intestine post-transplant. Exposure of ILC2s to proinflammatory cytokines resulted in a mixed ILC1-ILC2 phenotype but was able to convert only a small population of ILC2s to ILC1s, which were found post-transplant. Whereas ILC2s protected against acute graft-versus-host disease (aGVHD) mediated mortality, infusion of proinflammatory cytokine-exposed ILC2s accelerated aGvHD. Interestingly, murine ILC2 reconstitution post-HSCT is decreased in the presence of alloreactive T cells. Finally, peripheral blood cells from human patients with aGvHD have an altered ILC2-associated chromatin landscape compared to transplanted controls. These data demonstrate that following transplantation ILC2s convert to a pro-pathogenic population with an ILC1-like chromatin state and provide insights into the contribution of ILC plasticity to the impaired reconstitution of ILC2 cells, which is one of several potential mechanisms for the poor reconstitution of these important cells after allo-HSCT.

description: Continuous time quantum walks (CTQW) do not necessarily perform better than their classical counterparts, the continuous time random walks (CTRW). For one special graph, where a recent analysis showed that in a particular direction of propagation the penetration of the graph is faster by CTQWs than by CTRWs, we demonstrate that in another direction of propagation the opposite is true; In this case a CTQW initially localized at one site displays a slow transport. We furthermore show that when the CTQW's initial condition is a totally symmetric superposition of states of equivalent sites, the transport gets to be much more rapid.

description: A schematic NJL-type model is employed to investigate kaon and pion condensation in deconfined quark matter in the color-flavor locked (CFL) phase, explicitly referring to quark degrees of freedom. To that end we allow for non-vanishing pseudoscalar diquark condensates in addition to the scalar ones which constitute the CFL phase. Color neutrality is ensured by the appropriate choice of color chemical potentials. The dependence of the free energy in the Goldstone condensed phases on quark masses and charge chemical potentials is found to be in good qualitative -- in most cases also quantitative -- agreement with the predictions obtained within the effective Lagrangian approach.

Retraction in St’át’imcets : an ultrasonic investigation
Creators: name: Namdaran, Nahal
Publisher: name: University of British Columbia
Year: 2010

description: Retracted consonants and their effects on surrounding vowels have been widely investigated in Interior Salish languages (Bessell 1992, 1998ab; Remnant 1990; Shahin 1997, 2002; van Eijk 1987, 1997; McDowell 2004; inter alia). It has been claimed that retracted consonants (uvulars, pharyngeals, sometimes laryngeals, and a subset of coronal consonants postulated to be articulated with a secondary retracted tongue root position) often trigger retraction in neighbouring vowels. However, with the exception of McDowell (2004), previous studies in Salish have examined vowel retraction effects from the perspective of acoustic and/or phonological evidence, leaving unanswered the question of how retraction is achieved articulatorily. The current study uses ultrasound imaging of the tongue in conjunction with the acoustic signal to examine the articulations involved in St’át’imcets retraction. This investigation attempts to answer the following questions: (i) what are the physiological mechanisms involved in the production of St’át’imcets retracted consonants-both inherently retracted (q, qw, q’, q’w, x̌, x̌w, [pharyngeal], [pharyngeal]w, [pharyngeal]’, [pharyngeal]’w,) and secondarily retracted (c̲, c̲’, s̲, l̲, l̲’, and Lower dialect z, z’), and; (ii) what are the coarticulatory effects of St’át’imcets retracted consonants on adjacent vowels? Articulatory results indicate that all St’át’imcets retracted consonants are produced with significant tongue root retraction towards the lower pharyngeal wall. Uvular consonant articulation also involves an upper pharyngeal/posterior-uvular constriction made by the tongue dorsum; for retracted coronal consonants, the participation of a retracted and raised tongue dorsum varies across speakers. Concerning St’át’imcets vowel retraction effects, articulatory and acoustic results indicate that vowels /i/ and /u/ undergo retraction when adjacent to St’át’imcets retracted consonants, with surface retracted qualities differing between uvular consonant contexts and retracted coronal consonant contexts. Furthermore, St’át’imcets retracted consonants generally exhibit symmetrical coarticulatory effects on adjacent vowels. Apart from the much-needed articulatory description of St’át’imcets retracted consonants and vowel retraction effects, some issues emerge regarding the phonological representation of St’át’imcets retraction. For example, this study evaluates the extent to which phonetic variation is encoded in the phonological structure. The examined St’át’imcets retracted consonant articulation and coarticulatory patterns provide information useful in the study of retraction processes present in other languages (e.g. Arabic).

description: This reflection paper takes the 25th IUI conference milestone as an opportunity to analyse in detail the understanding of intelligence in the community: Despite the focus on intelligent UIs, it has remained elusive what exactly renders an interactive system or user interface "intelligent", also in the fields of HCI and AI at large. We follow a bottom-up approach to analyse the emergent meaning of intelligence in the IUI community: In particular, we apply text analysis to extract all occurrences of "intelligent" in all IUI proceedings. We manually review these with regard to three main questions: 1) What is deemed intelligent? 2) How (else) is it characterised? and 3) What capabilities are attributed to an intelligent entity? We discuss the community's emerging implicit perspective on characteristics of intelligence in intelligent user interfaces and conclude with ideas for stating one's own understanding of intelligence more explicitly.

description: The discovery of high-temperature superconductivity in La$_3$Ni$_2$O$_7$ at pressures above 14 GPa has spurred extensive research efforts. Yet, fundamental aspects of the superconducting phase, including the possibility of a filamentary character, are currently subjects of controversial debates. Conversely, a crystal structure with NiO$_6$ octahedral bilayers stacked along the $c$-axis direction was consistently posited in initial studies on La$_3$Ni$_2$O$_7$. Here we reassess this structure in optical floating zone-grown La$_3$Ni$_2$O$_7$ single crystals that show signs of filamentary superconductivity. Employing scanning transmission electron microscopy and single-crystal x-ray diffraction under high pressures, we observe multiple crystallographic phases in these crystals, with the majority phase exhibiting alternating monolayers and trilayers of NiO$_6$ octahedra, signifying a profound deviation from the previously suggested bilayer structure. Using density functional theory, we disentangle the individual contributions of the monolayer and trilayer structural units to the electronic band structure of La$_3$Ni$_2$O$_7$, providing a firm basis for advanced theoretical modeling and future evaluations of the potential of the monolayer-trilayer structure for hosting superconductivity.

description: Die Macht eines Betonmonolithen, Menschen Unentschlossenheit und Ratlosigkeit mit seinem Umgang zu schaffen, beweist der Leitturm im Augarten, Wiens ältesten Barockgarten. Das zur Zeit des II Weltkriegs entstandener Massivbau weist mit seiner brutalen Architektur repräsentativ auf negative historische Ereignisse die diese Zeit mit sich brachte. Aufgrund dessen wird er, hässlich und unerwünscht, als Erbe verweigert. Eine Erinnerungsstätte mit darunterliegendem Museum soll den Leitturm, ohne jeglichen Eingriff des Äußeren, einen Nutzen geben, dass Leben schafft, und somit Menschen einlädt, den Flakturm selbst, wie auch seine Geschichte, kennen zu lernen.
description: The power of a concrete monolyth leaving people in determination and helplessness for decades can be seen from the Leitturm in Viennas oldest barock garden called Augarten. The solid construction was built during World War II and represents with its brutal architecture all the negative happenings from this time. As a result of these, its been seen as ugly and unwanted and therefore refused as a heritage. A memorial place with a museum underneath should, withouth any external inervention, finaly give this monolyth a new function by animating it and opening it up to a general public, inviting them to come, join in and discover a new way of learning more about Flakturm itself and its history.

description: Iron oxide nanoparticles were prepared by sol -gel process. Insitu polymerization of pyrrole monomer in the presence of oxygen in iron oxide ethanol suspension resulted in a iron oxide - polypyrrole nanocomposite. The structure and magnetic properties were investigated for varying pyrrole concentrations. The presence of the gamma - iron oxide phase and polypyrrole were confirmed by XRD and FTIR respectively. Agglomeration was found to be comparatively much reduced for the coated samples, as shown by TEM. AC susceptibility measurements confirmed the superparamagnetic behaviour. Numerical simulations performed for an interacting model system are performed to estimate the anisotropy and compare favourably with experimental results.

description: Background Imposter phenomenon (IP) is common in medicine. An intervention from the business world, the Reflected Best Self Exercise (RBSE), in which an individual elicits stories of themselves at their best, has not been studied in medical residents. Objective To determine the feasibility of implementing the RBSE and its potential for reducing IP in residents. Methods All incoming internal medicine and medicine-pediatrics interns in the 2022-2023 academic year at a single institution were invited to complete the RBSE. Participants elicited stories from contacts prior to beginning residency and received their stories during intern orientation in a 1-hour session led by one author with no prior training. Cost and time requirements were assessed. IP was measured via the Clance Impostor Phenomenon Scale (CIPS) at baseline, 1 month, and 6 months following the RBSE. Informal feedback on the RBSE was collected via surveys at 1 month and 6 months. Results Nineteen of 35 interns (54.3%) completed the RBSE. It cost $75 per participant, for a total cost of $1,425. Twenty-eight of 35 (80%) completed the baseline CIPS, with scores similar between participants and nonparticipants (64.9 vs 68.9). CIPS scores were lower in participants at 1 month (57.6 vs 69.6) and 6 months (55.6 vs 64.5) but did not meet statistical significance. Survey feedback from participants suggested the intervention was beneficial. Conclusions Implementing the RBSE in residents was feasible with reasonable cost and time commitment. It appeared highly acceptable to residents, with some promise of effects on an IP scale.

description: A one-dimensional Bose-Einstein condensate may experience nonlinear periodic modulations known as "cnoidal waves". We argue that such structures represent promising candidates for the study of supersolidity-related phenomena in a non-equilibrium state. A mean-field treatment makes it possible to rederive Leggett's formula for the superfluid fraction of the system and to estimate it analytically. We determine the excitation spectrum, for which we obtain analytical results in the two opposite limiting cases of (i) a linearly modulated background and (ii) a train of dark solitons. The presence of two Goldstone (gapless) modes -- associated with the spontaneous breaking of $\mathrm{U}(1)$ symmetry and of continuous translational invariance -- at large wavelength is verified. We also calculate the static structure factor and the compressibility of cnoidal waves, which show a divergent behavior at the edges of each Brillouin zone.

description: The possibility of a Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state in a population imbalanced Fermi gas with a vortex is proposed. Employing the Bogoliubov-de-Gennes formalism we self-consistently determine the superfluid order parameter and the particle number density in the presence of a vortex. We find that as increasing population imbalance, the superfluid order parameter spatially oscillates around the vortex core in the radial direction, indicating that the FFLO state becomes stable. We find that the radial FFLO states cover a wide region of the phase diagram in the weak-coupling regime at $T=0$ in contrast to the conventional case without a vortex. We show that this inhomogeneous superfluidity can be detected as peak structures of the local polarization rate associated with the node structure of the superfluid order parameter. Since the vortex in the 3D Fermi gas with population imbalance has been already realized in experiments, our proposal is a promising candidate of the FFLO state in cold atom physics.
