description: Fluences of solar energetic particles (SEPs) are not easy to evaluate, especially for high-energy events (i.e. ground-level enhancements, GLEs). Earlier estimates of event-integrated SEP fluences for GLEs were based on partly outdated assumptions and data, and they required revisions. Here, we present the results of a full revision of the spectral fluences for most major SEP events (GLEs) for the period from 1956 -- 2017 using updated low-energy flux estimates along with greatly revisited high-energy flux data and applying the newly invented reconstruction method including an improved neutron-monitor yield function. Low- and high-energy parts of the SEP fluence were estimated using a revised space-borne/ionospheric data and ground-based neutron monitors, respectively. The measured data were fitted by the modified Band function spectral shape. The best-fit parameters and their uncertainties were assessed using a direct Monte Carlo method. As a result, a full reconstruction of the event-integrated spectral fluences was performed in the energy range above 30 MeV, parametrised, and tabulated for easy use along with estimates of the 68% confidence intervals. This forms a solid basis for more precise studies of the physics of solar eruptive events and the transport of energetic particles in the interplanetary medium, as well as the related applications.

description: Magnetotransport properties are investigated for a high mobility Si two dimensional electron systems in the vicinity of a Landau level crossing point. At low temperatures, the resistance peak having a strong anisotropy shows large hysteresis which is attributed to Ising quantum Hall ferromagnetism. The peak is split into two peaks in the paramagnetic regime. A mean field calculation for the peak positions indicates that electron scattering is strong when the pseudospin is partially polarized. We also study the current-voltage characteristics which exhibit a wide voltage plateau.

description: Single photonic applications - such as quantum key distribution - rely on the transmission of single photons, and require the ultimate sensitivity that an optical detector can achieve. Single-photon detectors must convert the energy of an optical pulse containing a single photon into a measurable electrical signal. We report on fiber-coupled superconducting single-photon detectors (SSPDs) with specifications that exceed those of avalanche photodiodes (APDs), operating at telecommunication wavelength, in sensitivity, temporal resolution and repetition frequency. The improved performance is demonstrated by measuring the intensity correlation function g(2)(t) of single-photon states at 1300nm produced by single semiconductor quantum dots (QDs).

Parenting the pre-school aged child with asthma : a secondary analysis using the Canam adaptive task framework
Creators: name: Meyerhoff, Heather P.
Publisher: name: University of British Columbia
Year: 2009

description: A significant population of children and their families manage chronic illness as part of their daily lives. Asthma is one of the most common acute and chronic diseases in children and accounts for a major cause of school absenteeism, visits to emergency departments, and hospital admissions. The family, primarily the parents, must take on the responsibility of caring for these children on a day-to-day basis. The Canam Adaptive Task Framework (ATF) identifies and describes the common adaptive tasks facing parents in managing their child's chronic condition and is useful in guiding assessment and interventions with these parents. The purpose of this study was to identify the adaptive tasks from the Canam ATF that were expressed by parents of pre-school aged children with asthma in part of a previously existing qualitative data set. The research question for this study was: Does the Canam ATF fully accommodate the expressions of parenting the pre-school age child with asthma using an existing set of interview data? Qualitative data for this study were originally collected as part of a larger study. Interview data from 10 mothers and 8 fathers in 10 families, were selected from this larger study for participation in this secondary analysis. Each family was interviewed three times and their verbatim interview transcripts were1 analyzed using latent content analysis techniques. The Canam ATF provided the conceptual framework and content codes to guide the analysis. The findings in this study were categorized and discussed according to the Canam ATF and the literature. It is significant that all of the adaptive tasks in the ATF were accounted for in the data and that no new categories were identified. Therefore, it is concluded that the Canam ATF was able to folly accommodate the expressions of parenting a pre-school aged child with asthma. Although many of the findings are specific to the management of asthma, the overriding principles may be applied to children with other chronic illnesses. One role of the nurse is to assess whether or not parents are accomplishing each task, and if not, to assist them to acquire the necessary knowledge, skills, or resources they need to enable them to achieve the task.

Does preregistration improve the credibility of research findings?

Subjects: subject: Other Statistics (stat.OT)

description: Preregistration entails researchers registering their planned research hypotheses, methods, and analyses in a time-stamped document before they undertake their data collection and analyses. This document is then made available with the published research report to allow readers to identify discrepancies between what the researchers originally planned to do and what they actually ended up doing. This historical transparency is supposed to facilitate judgments about the credibility of the research findings. The present article provides a critical review of 17 of the reasons behind this argument. The article covers issues such as HARKing, multiple testing, p-hacking, forking paths, optional stopping, researchers' biases, selective reporting, test severity, publication bias, and replication rates. It is concluded that preregistration's historical transparency does not facilitate judgments about the credibility of research findings when researchers provide contemporary transparency in the form of (a) clear rationales for current hypotheses and analytical approaches, (b) public access to research data, materials, and code, and (c) demonstrations of the robustness of research conclusions to alternative interpretations and analytical approaches.

description: On-chip super-resolution optical microscopy is an emerging field relying on waveguide excitation with visible light. Here, we investigate two commonly used high-refractive index waveguide platforms, tantalum pentoxide (Ta$_2$O$_5$) and silicon nitride (Si$_3$N$_4$), with respect to their background with excitation in the range 488-640 nm. The background strength from these waveguides were estimated by imaging fluorescent beads. The spectral dependence of the background from these waveguide platforms was also measured. For 640 nm wavelength excitation both the materials had a weak background, but the background increases progressively for shorter wavelengths for Si3N4. We further explored the effect of the waveguide background on localization precision of single molecule localization for direct stochastic optical reconstruction microscopy (dSTORM). An increase in background for Si$_3$N$_4$ at 488 nm is shown to reduce the localization precision and thus the resolution of the reconstructed images. The localization precision at 640 nm was very similar for both the materials. Thus, for shorter wavelength applications Ta$_2$O$_5$ is preferable. Reducing the background from Si$_3$N$_4$ at shorter wavelengths via improved fabrication will be worth pursuing.
Polycylcic Aromatic Hydrocarbons (PAH's) in dense cloud chemistry

description: Virtually all detailed gas-phase models of the chemistry of dense interstellar clouds exclude polycyclic aromatic hydrocarbons (PAH's). This omission is unfortunate because from the few studies that have been done on the subject, it is known that the inclusion of PAH's can affect the gas-phase chemistry strongly. We have added PAH's to our network to determine the role they play in the chemistry of cold dense cores. In the models presented here, we include radiative attachment to form PAH-, mutual neutralization between PAH anions and small positively-charged ions, and photodetachment. We also test the sensitivity of our results to changes in the size and abundance of the PAH's. Our results confirm that the inclusion of PAH's changes many of the calculated abundances of smaller species considerably. In TMC-1, the general agreement with observations is significantly improved contrary to L134N. This may indicate a difference in PAH properties between the two regions. With the inclusion of PAH's in dense cloud chemistry, high-metal elemental abundances give a satisfactory agreement with observations. As a result, we do not need to decrease the observed elemental abundances of all metals and we do not need to vary the elemental C/O ratio in order to produce large abundances of carbon species in TMC-1 (CP).

description: Polar materials can host a variety of topologically significant magnetic phases, which often emerge from a modulated magnetic ground state. Relatively few noncentrosymmetric tetragonal materials have been shown to host topological spin textures and new candidate materials are necessary to expand the current theoretical models. This manuscript reports on the anisotropic magnetism in the polar, tetragonal material NdCoGe$_3$ via thermodynamic and neutron diffraction measurements. The previously reported $H$-$T$ phase diagram is updated to include several additional phases, which exist for both $H$ = 0 and with an applied field H$\perp$ c. Neutron diffraction data reveal that the magnetic structures below $T_{N1}$ = 3.70 K and $T_{N2}$ = 3.50 K are incommensurate, with a ground state magnetic order that is incommensurate in all directions with the propagation vector $\vec{k}$ = (0.494, 0.0044, 0.385) at 1.8 K. A unique magnetic structure solution is not achievable, but the possible single and multi-$\vec{k}$ spin models are discussed. These results demonstrate that NdCoGe3 hosts complicated magnetic order derived from modulated magnetic moments.

description: La medicina narrativa come  una pratica comunicativa che orienta la cura verso la persona e si è segnalato che, per aver a che fare con la persona e non intrattenersi nel sicuro territorio dell’ente malattia,  ci si debba avventurare nella dimensione della prospettiva di chi si ha di fronte, ponendo il mondo abituale del paziente e l’ordine di senso che in lui si costituisce all’interno della relazione di cura. Si ritiene che sotto la cifra dell’identità narrativa,  che mostra la dinamicità dell’identità personale, l’intreccio tra i racconti e la riconfigurazione del sé,  sia possibile indicare delle modalità di relazione intersoggettiva nelle quali  la narrazione  è in grado di orientare la cura verso la persona. Attraverso la narrazione  è possibile manifestare  il senso di quel qualcosa che la persona, che è  stata messa tra parentesi dall’apparato diagnostico, vorrebbe dire al medico e che rimane nascosto rispetto al discorso sull’ente. Rimuovendo questa sorta di epochè, il processo diagnostico e terapeutico incentrato sull’ente è ricompreso nella dialettica tra spiegazione  e comprensione, nel territorio  antropologico della ricerca di una concordanza sul piano di cura.

title: Solution-Processable Polymer Photocatalysts for Hydrogen Evolution from Water
Creators: name: Woods, DJ
Publisher: name: University of Liverpool Repository
Year: 2019

description: Methods of storing renewable energy are urgently required to meet future energy demands. Photocatalytic hydrogen production from water represents an attractive method of storing solar energy for a diverse range of end-use applications. Semiconducting polymers are an emerging class of photocatalysts with eminently tunable structures and properties. However, the insolubility of most polymer photocatalysts limits processability and, therefore, opportunities to optimise the morphology of these materials for photocatalytic applications. Processability was achieved with the introduction of solubilising side-chains, which were systematically varied in order to study their influence on the photocatalytic performance of polymers. It was found that high hydrogen evolution rates could be achieved by incorporating oligo(ethylene glycol) side-chains, which seem to promote interaction with water during photocatalysis as well as affording solubility in common organic solvents. The polymer backbone was also varied to further improve the performance of solution-processable polymer photocatalysts. A fluorene-based polymer, FS-TEG, was prepared that displayed high activity under visible light, with an external quantum efficiency of 10.0% at 420 nm. Polymers were processed into a variety of forms, including photocatalytic films, both free-standing and cast on substrates. The substrate was varied to improve performance, with roughened glass slides found to achieve the highest areal hydrogen evolution rates. Photocatalytic polymers were also cast on planar substrates, which enabled precise control over film formation. Important parameters such as optimum film thicknesses for hydrogen evolution performance were subsequently established. Processability also enabled facile preparation of composites and blends. Incorporation of a narrow band gap dye was shown to triple the hydrogen evolution rate of FS-TEG films while the formation of heterojunctions with inorganic photocatalysts also enhanced performance. The scope for fabricating composites of this kind is boundless and, in the long term, devices capable of overall water splitting that utilise these materials are envisaged.

description: (abridged) In this paper, we examined XMM Newton EPIC spectra of 14 ultra-luminous X-ray sources (ULXs)in addition to the XMM RGS spectra of two sources (Holmberg II X-1 and Holmberg IX X-1). We determined oxygen and iron abundances of the host galaxy's interstellar medium (ISM) using K-shell (O) and L-shell (Fe) X-ray photo-ionization edges towards these ULXs. We found that the oxygen abundances closely matched recent solar abundances for all of our sources, implying that ULXs live in similar local environments despite the wide range of galaxy host properties. Also, we compare the X-ray hydrogen column densities (n_H) for 8 ULX sources with column densities obtained from radio H I observations. The X-ray model n_H values are in good agreement with the H I n_H values, implying that the hydrogen absorption towards the ULXs is not local to the source (with the exception of the source M81 XMM1). In order to obtain the column density and abundance values, we fit the X-ray spectra of the ULXs with a combined power law and one of several accretion disk models. We tested the abundances obtained from the XSPEC models bbody, diskbb, grad, and diskpn along with a power law, finding that the abundances were independent of the thermal model used. We comment on the physical implications of these different model fits. We also note that very deep observations allow a breaking of the degeneracy noted by Stobbart et al. (2006) favoring a high mass solution for the absorbed grad + power law model.

description: Symmetries in an open quantum system lead to degenerated Liouvillian that physically implies the existence of multiple steady states. In such cases, obtaining the initial condition independent stead states is highly nontrivial since any linear combination of the \emph{true} asymptotic states, which may not necessarily be a density matrix, is also a valid asymptote for the Liouvillian. Thus, in this work we consider different approaches to obtain the \emph{true} steady states of a degenerated Liouvillian. In the ideal scenario, when the open system symmetry operators are known we show how these can be used to obtain the invariant subspaces of the Liouvillian and hence the steady states. We then discuss two other approaches that do not require any knowledge of the symmetry operators. These could be a powerful tool to deal with quantum many-body complex open systems. The first approach which is based on Gramm-Schmidt orthonormalization of density matrices allows us to obtain \emph{all} the steady states, whereas the second one based on large deviations allows us to obtain the non-degenerated maximum and minimum current-carrying states. We discuss our method with the help of an open para-Benzene ring and examine interesting scenarios such as the dynamical restoration of Hamiltonian symmetries in the long-time limit and apply the method to study the eigenspacing statistics of the nonequilibrium steady state.

description: The ground state of Shor-Movassagh chain can be analytically described by the Motzkin paths. There is no analytical description of the excited states, the model is not solvable. We prove the integrability of the model without interacting part in this paper [free Shor-Movassagh]. The Lax pair for the free Shor-Movassagh open chain is explicitly constructed. We further obtain the boundary $K$-matrices compatible with the integrability of the model on the open interval. Our construction provides a direct demonstration for the quantum integrability of the model, described by Yang-Baxter algebra. Due to the lack of crossing unitarity, the integrable open chain can not be constructed by the reflection equation (boundary Yang-Baxter equation).

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The paper presents the results of three-dimensional (3D) modelling of the structure and the emission of accretion columns formed above the surface of accreting strongly magnetized neutron stars under the circumstances when a pressure of the photons generated in the column base is enough to determine the dynamics of the plasma flow. On the foundation of numerical radiation hydrodynamic simulations, several 3D models of accretion column are constructed. The first group of the models contains spatially 3D columns. The corresponding calculations lead to the distributions of the radiation flux over the sidewalls of the columns which are not characterized by axial symmetry. The second group includes the self-consistent modelling of spectral radiative transfer and two-dimensional spatial structure of the column, with both thermal and bulk Comptonization taken into account. The changes in the structure of the column and the shape of X-ray continuum are investigated depending on physical parameters of the model.

description: An ensemble of uncoupled limit-cycle oscillators receiving common Poisson impulses shows a range of non-trivial behavior, from synchronization, desynchronization, to clustering. The group behavior that arises in the ensemble can be predicted from the phase response of a single oscillator to a given impulsive perturbation. We present a theory based on phase reduction of a jump stochastic process describing a Poisson-driven limit-cycle oscillator, and verify the results through numerical simula- tions and electric circuit experiments. We also give a geometrical interpretation of the synchronizing mechanism, a perturbative expansion to the stationary phase distribution, and the diffusion limit of our jump stochastic model.
Space, imagination and Vitruvius in archaeological [re]construction : reconsidering a modus operandi
Creators: name: Millette, Daniel M.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis challenges the way hypothetical Vitruvius-based classical theatre [reconstructions are readily undertaken and accepted in conventional architectural and archaeological research. The cultural matrix born out of the settling of the Roman provinces—in this case, Gaul—was one which evolved out of the adaptation and adoption of mores, crafts, techniques and meanings of meeting cultures; cultural and geographical context were inextricably linked to a region-specific architecture. In Gaul, there remain enough examples to state that the theatre probably deviated substantially from the design tenets elucidated by Vitruvius. Analysis of a hypothetical architecturally [reconstructed theatre—that of Saint-Bertrand-de-Comminges—reveals that the [reconstruction is based on sparse archaeological evidence and, for the most part, is grounded within an imaginative interpretation of Vitruvius' broad Roman theatre design tenets. The [reconstruction recalls Vitruvius' Book V section on theatres but neglects archaeologically revealed architectonic details that highlight the monument as one which deviates from Vitruvius' Roman model. Thus, from the historical and cultural evidence, including an overview of Gaul's extant theatre remains, and from an analysis of one such [reconstruction, it is unlikely that Vitruvius can be relied upon with any certainty to [reconstruct Gaul's theatres. The epistemology of the interpretation of the De architectura libri decern suggests that the tradition of [reconstructing monuments—in this case, theatres—is mired within a set of "tendencies" that exist within the architectural and archaeological professions: The tendency to borrow Vitruvius as a means to render authority to one's work, the tendency to use the treatise within a didactic framework, the tendency to position the text vis-a-vis the study of classical monuments and vice versa, and the tendency to use "imagined" illustrations within translations of Vitruvius' work and similar treatises, have all been part of a process through which a canonization of Vitruvius' writings has taken place. It is through this process that [re]construction by means of the text has become accepted and condoned within the architectural and archaeological professions.

description: We study the efficiency at the maximal power $η_\mathrm{max}$ of a finite-time Carnot cycle of a weakly interacting gas which we can reagard as a nearly ideal gas. In several systems interacting with the hot and cold reservoirs of the temperatures $T_\mathrm{h}$ and $T_\mathrm{c}$, respectively, it is known that $η_\mathrm{max}=1-\sqrt{T_\mathrm{c}/T_\mathrm{h}}$ which is often called the Curzon-Ahlborn (CA) efficiency $η_\mathrm{CA}$. For the first time numerical experiments to verify the validity of $η_\mathrm{CA}$ are performed by means of molecular dynamics simulations and reveal that our $η_\mathrm{max}$ does not always agree with $η_\mathrm{CA}$, but approaches $η_\mathrm{CA}$ in the limit of $T_\mathrm{c} \to T_\mathrm{h}$. Our molecular kinetic analysis explains the above facts theoretically by using only elementary arithmetic.

description: Natural and resonant oscillations of suspended circular graphene and hexagonal boron nitride (h-BN) membranes (single-layer sheets lying on a flat substrate having a circular hole of radius $R$) have been simulated using full-atomic models. Substrates formed by flat surfaces of graphite and h-BN crystal, hexagonal ice, silicon carbide 6H-SiC and nickel surface (111) have been used. The presence of the substrate leads to the forming of a gap at the bottom of the frequency spectrum of transversal vibrations of the sheet. The frequencies of natural oscillations of the membrane (oscillations localized on the suspended section of the sheet) always lie in this gap, and the frequencies of oscillations decrease by increasing radius of the membrane as $(R+R_i)^{-2}$ with nonezero effective increase of radius $R_i>0$. The modeling of the sheet dynamics has shown that small periodic transversal displacements of the substrate lead to resonant vibrations of the membranes at frequencies close to eigenfrequencies of nodeless vibrations of membranes with a circular symmetry. The energy distribution of resonant vibrations of the membrane has a circular symmetry and several nodal circles, whose number $i$ coincides with the number of the resonant frequency. The frequencies of the resonances decrease by increasing the radius of the membrane as $(R+R_i)^{α_i}$ with exponent $α_i<2$. The lower rate of resonance frequency decrease is caused by the anharmonicity of membrane vibrations.

description: We show that for a $λϕ^4$ theory having many components, the solution with all equal components in the infrared regime is stable with respect to our expansion given by a recently devised approach to analyze strongly coupled quantum field theory. The analysis is extended to a pure Yang-Mills theory showing how, in this case, the given asymptotic series exists. In this way, many components theories in the infrared regime can be mapped to a single component scalar field theory obtaining their spectrum.

description: The Internet of Things adoption in the manufacturing industry allows enterprises to monitor their electrical power consumption in real time and at machine level. In this paper, we follow up on such emerging opportunities for data acquisition and show that analyzing power consumption in manufacturing enterprises can serve a variety of purposes. Apart from the prevalent goal of reducing overall power consumption for economical and ecological reasons, such data can, for example, be used to improve production processes. Based on a literature review and expert interviews, we discuss how analyzing power consumption data can serve the goals reporting, optimization, fault detection, and predictive maintenance. To tackle these goals, we propose to implement the measures real-time data processing, multi-level monitoring, temporal aggregation, correlation, anomaly detection, forecasting, visualization, and alerting in software. We transfer our findings to two manufacturing enterprises and show how the presented goals reflect in these enterprises. In a pilot implementation of a power consumption analytics platform, we show how our proposed measures can be implemented with a microservice-based architecture, stream processing techniques, and the fog computing paradigm. We provide the implementations as open source as well as a public demo allowing to reproduce and extend our research.

title: Crystal Engineering and Structural Solutions of Organic Molecular Materials

description: Organic molecular materials have been studied for decades, with a strong focus on their application within gas uptake and selective separations. Porous organic molecules can come in multiple forms, whether a discrete molecule such as a macrocycle or cage, or an infinite framework, such as a hydrogen bonded organic framework (HOF). In this thesis, we will examine the benefits of crystal engineering as an alternative route towards the formation of new organic molecular structures. The molecular structures discussed in this thesis include organic molecular cages, hydrogen bonded organic frameworks and organic co-crystals. Crystal engineering has been posed as an impressive method for the discovery of new materials, without the time costly effort of finding alternative precursors, or finding the best possible reaction conditions. There are multiple routes towards recrystallisation, which are suitable whether soluble or insoluble, which can be utilised to direct alternative crystal packing, hence, alternative functionality. The dynamic nature of organic molecular cages, which are synthesised via reversible imine condensation reactions, is discussed in detail in chapter 2. TCC1[3+6], a trigonal prismatic cage underwent re-equilibration in solution to the truncated tetrahedron cage, stoichiometrically twice the equivalent, TCC1[6+12]. The cage formation was optimised synthetically, and furthermore experimental observations were rationalised through computational analyses. A series of organic molecular cages were synthesised via high throughput techniques using robotics, which were then fully characterised and their crystal structures determined. From this, a series of discoveries were made, including further illustration of re-equilibration in C21, from a [3+2] cage to a [6+4]. The formation of a new topology for C18 was also discovered, a bridged catenane with a novel topology not previously seen in literature. High throughput methods were also used in Chapter 4. However as opposed to the modelling the potential structure in silico, as in Chapter 3, the cages were chosen based on precursors capable of hydrogen bonding or organic salt formation. We showed it is possible to synthesised porous co-crystals from small organics, and furthermore discuss the benefits of using a bespoke high throughput infra-red kit, capable of determining the isosteric heat of adsorption. Porous structures by strategic design are also discussed in chapter 4, focusing on an alternative method using both crystal structure prediction (CSP) and energy-structure-function maps (ESFs) to increase the rate of porous material discovery. T1 and T2 are both triptycene-based hydrogen bonding tectons, which are capable of forming hydrogen-bonded organic frameworks. The ESFs enabled rationalisation of the experimental findings, and furthermore provided insight into the importance of hydrogen bond donors and acceptors through comparison of T1 and T2.

description: We report an ultrahigh resolution resonant inelastic x-ray scattering (RIXS) study of the in-plane bond-stretching phonon mode in stripe-ordered cuprate La$_{1.675}$Eu$_{0.2}$Sr$_{0.125}$CuO$_4$. Phonon softening and lifetime shortening are found around the charge ordering wave vector. In addition to these self-energy effects, the electron-phonon coupling is probed by its proportionality to the RIXS cross section. We find an enhancement of the electron-phonon coupling around the charge-stripe ordering wave vector upon cooling into the low-temperature tetragonal structure phase. These results suggest that in addition to electronic correlations, electron-phonon coupling contributes significantly to the emergence of long-range charge-stripe order in cuprates.

description: We describe quantization designs which lead to asymptotically and order optimal functional quantizers. Regular variation of the eigenvalues of the covariance operator plays a crucial role to achieve these rates. For the development of a constructive quantization scheme we rely on the knowledge of the eigenvectors of the covariance operator in order to transform the problem into a finite dimensional quantization problem of normal distributions. Furthermore we derive a high-resolution formula for the $L^2$-quantization errors of Riemann-Liouville processes.

description: Baxter's Q-operator for the quantum transfer matrix of the XXZ spin-chain is constructed employing the representation theory of quantum groups. The spectrum of this Q-operator is discussed and novel functional relations which describe the finite temperature regime of the XXZ spin-chain are derived. For non-vanishing magnetic field the previously known Bethe ansatz equations can be replaced by a system of quadratic equations which is an important advantage for numerical studies. For vanishing magnetic field and rational coupling values it is argued that the quantum transfer matrix exhibits a loop algebra symmetry closely related to the one of the classical six-vertex transfer matrix at roots of unity.

description: The James Webb Space Telescope (JWST) will revolutionise our understanding of early galaxy formation, and could potentially set stringent constraints on the nature of dark matter. We use a semi-empirical model of galaxy formation to investigate the extent to which uncertainties in the implementation of baryonic physics may be degenerate with the predictions of two different models of dark matter -- Cold Dark Matter (CDM) and a 7 keV sterile neutrino, which behaves as Warm Dark Matter (WDM). Our models are calibrated to the observed UV luminosity function at $z=4$ using two separate dust attenuation prescriptions, which manifest as high and low star formation efficiency in low mass haloes. We find that while at fixed star formation efficiency, $\varepsilon$, there are marked differences in the abundance of faint galaxies in the two dark matter models at high-$z$, these differences are mimicked easily by varying $\varepsilon$ in the same dark matter model. We find that a high $\varepsilon$ WDM and a low $\varepsilon$ CDM model -- which provide equally good fits to the $z=4$ UV luminosity function -- exhibit nearly identical evolution in the cosmic stellar mass and star formation rate densities. We show that differences in the star formation rate at fixed stellar mass are larger for variations in $\varepsilon$ in a given dark matter model than they are between dark matter models; however, the scatter in star formation rates is larger between the two models than they are when varying $\varepsilon$. Our results suggest that JWST will likely be more informative in constraining baryonic processes operating in high-$z$ galaxies than it will be in constraining the nature of dark matter.
