Year: 2023

description: Background
 Placements in general practice play an important role in undergraduate medical education and have a strong influence on students and junior doctors choosing careers in general practice. However GP educators report that practice workloads and lack of space are major challenges impacting medical student placements. Without increasing capacity these issues are expected to worsen as increasing numbers of learners compete for limited space.

 Summary of Work
 Kent and Medway Medical School (KMMS) students undertake six one-week-long placements in general practice in their first and second years termed ‘immersion weeks’. Each immersion week has a theme which corresponds with on-campus learning for systems-based modules. In the 2022/23 academic year the immersion week structured was changed, with one day of the week replaced with a half day of campus teaching and a half day of ‘asynchronous learning’. The asynchronous learning comprises an e-learning lesson created using the Xerte Online Toolkit and hosted on the university virtual learning environment. The content is designed to complement students’ learning on placement while referencing their on-campus learning in systems-based modules. Each lesson includes a mixture of case-discussions, multimedia and interactive elements which students can complete at their own pace.

 Summary of Results
 All year one and two students were invited to provide feedback after the third immersion weeks. 78/131 (60%) year one and 85/106 (80%) year two students responded. On a 5-point Likert scale 52/78 (67%) of year one students and 63/85 (74%) year two students either agreed or strongly agreed with the statement ‘the asynchronous material was helpful in supporting my learning’. Students found the asynchronous lessons to be a useful way of consolidating knowledge ahead of the placement and found it beneficial that they could complete it at their own pace. However issues with technology caused frustration for some.

 Discussion and Conclusion
 Most students found asynchronous learning helpful in supporting their learning. This highlights the potential for a blended learning approach utilising e-learning to enhance undergraduate general practice placements and to ease pressures on capacity in primary care.

 Take Home Messages
 A ‘flipped placement’ approach utilising e-learning can complement undergraduate primary care placements and assist in easing the pressures of capacity for teaching practices.

description: Clinical environments are environments where confusion and uncertainty abound. And in the clinical context of medical education, students often encounter unexpected and challenging aspects of complex environments that overwhelm them emotionally. Doctors understand patients in these clinical environments as long as they first understand themselves as individuals and have developed themselves emotionally against uncertainties.
 This awareness-raising project is important, because based on the relevant literature, areas of medical humanities and especially art activities are known to contribute to medical students’ emotional well-being in many aspects like mindfulness, empathy, creativity, coping with uncertainty.
 Relatedly, the students participating in this research were expected to make progress in terms of addressing their lives and feelings in clinical settings in depth, making sense of their own feelings, improving their reflective and narrative competence and establishing a professional identity.
 As artistic encounters are known to trigger seminal developments both individually and socially, artistic activities of several kinds like museum visits, workshops and electives have been in curricula at medical schools for a few decades. However, long-term art education has been a very rare experience.
 This project on art workshops was carried out for clinical phase medical students and residents, and hosted 23 active participants. The process took place a whole year starting from October 2021 until the art exhibition in November 2022. The artistic activities offered to participants were painting and story-making workshops held almost every other week. Reflection sessions were also held while the art workshops were going on, and each participant’s reflection on their own emotional experiences in clinical setting and how the art workshop helped them was taken. Also one on one interviews with each participant was made to add up to the qualitative data collected in this project.
 The art workshops project was wrapped up with an exhibition of art products created during these workshops. The exhibition included 23 stories, 3 poems, 1 caricature and 12 paintings from 23 participants.
 With this project, a long-term art workshops project has been introduced in the context of medical education with visual and literary fields of art. The positive accounts of the project participants as well as the huge interest of visitors of the exhibition illustrate the appreciation and the obvious need for artistic activities in medical schools.
 The original value of this research is that it will form the basis for the design of new art programs with reflection and narrative patterns in medical schools.
title: An Assessment of Four-Hour Sample Durations Used to Determine Full-Shift Noise Exposures in a Foundry
Creators: name: Fleming, Vince Marlo
Publisher: name: Old Dominion University Libraries

description: Full-shift sampling, usually eight hours, is traditionally performed to assess daily occupational noise exposure. This sampling approach is inefficient, and costly for repeated, long-term exposure evaluations. This study assessed the use of four-hour sample durations and subsequent data analysis to determine daily occupational noise exposures in a foundry. The four-hour sample durations were extracted from full-shift samples and analyzed on their ability to provide valid data for estimating mean daily noise exposure levels without significantly affecting sampling precision or accuracy. Results of this study indicate four-hour sample durations can be used successfully to estimate full-shift noise exposures provided certain criteria are met. Findings of this study may reduce the sampling time and number of samples required to make decisions regarding employee noise exposures.
Curing critical links in oscillator networks as power grid models

description: Modern societies crucially depend on the robust supply with electric energy. Blackouts of power grids can thus have far reaching consequences. During a blackout, often the failure of a single infrastructure, such as a critical transmission line, results in several subsequent failures that spread across large parts of the network. Preventing such large-scale outages is thus key for assuring a reliable power supply. Here we present a non-local curing strategy for oscillatory power grid networks based on the global collective redistribution of loads. We first identify critical links and compute residual capacities on alternative paths on the remaining network from the original flows. For each critical link, we upgrade lines that constitute bottlenecks on such paths. We demonstrate the viability of this strategy for random ensembles of network topologies as well as topologies derived from real transmission grids and compare the nonlocal strategy against local back-ups of critical links. These strategies are independent of the detailed grid dynamics and combined may serve as an effective guideline to reduce outages in power grid networks by intentionally strengthen optimally selected links.

description: It has been recently demonstrated that superconducting transition edge sensors (TESs) behave as weak-links due to longitudinally induced superconductivity from the leads with higher Tc. In this work we study the implication of this behaviour for TES-based bolometers and microcalorimeter under ac bias. The TESs are read-out at frequencies between 1 and 5 MHz by a Frequency Domain Multiplexer based on a linearised two-stage SQUID amplifier and high- Q lithographically made superconducting LC resonators. In particular, we focus on SRON TiAu TES bolometers with a measured dark Noise Equivalent Power (NEP) of $3.2 \cdot 10^{-19} W/Hz^{1/2}$ developed for the short wavelength band for the instrument SAFARI on the SPICA telescope.

description: We explore the behaviour of the inverse reduced density fluctuations and the isobaric expansion coefficient using α,ω-dibromoalkanes as an example. Two different states are revealed far from the critical point: the region of exponentially decaying fluctuations near the coexistence curve and the state with longer correlations under sufficiently high pressures. The crossing of the isotherms of the isobaric expansion coefficient occurs within the PVT range of the mentioned transition. We discuss the interplay of this crossing with the changes in molecular packing structure connected with the analysed function of the density, which represents inverse reduced volume fluctuations.

Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: The aim of this quality improvement project was to evaluate the impact of the Patient Health Questionnaire-9 (PHQ-9) in identifying persons with depression and to develop recommendations on improving the process of screening and managing depression in a primary care practice. A primary care practice in suburban New Jersey wanted to enhance its diagnosis and identification of depression among its clinic population. The practice site switched their previous standard of using a PHQ-2 to a PHQ-9 in March 2022. This project aimed to assess the difference in the number of patients identified with depression using the more elaborate PHQ-9 and to make recommendations to enhance their mental health screening protocol.Methodology: Retrospective chart review was used to assess the differences in the rates of depression identified using the PHQ-9. Charts were reviewed for 3 months prior to implementation of the PHQ-9 and for 3 months after implementation of the screening tool. Results: A total of 394 charts were reviewed for the entire project. In the pre-intervention phase, 5 individuals out of 158 persons screened, had a positive screen for depression. In the post-intervention phase 40 out of 191 screened positive for depression. Implications for Practice: Use of a more elaborate screening tool, may enhance detection in this primary care practice. Clinicians should consider using the PHQ-9 if time and capacity allow for a more in-depth screening. Keywords: depression screening, PHQ-2, PHQ-9, primary care.

description: With reduced degrees of freedom, structural defects are expected to play a greater role in two-dimensional materials in comparison to their bulk counterparts. In particular, mechanical strength, electronic properties, and chemical reactivity are strongly affected by crystal imperfections in the atomically thin limit. Here, ultra-high vacuum (UHV) scanning tunneling microscopy (STM) and spectroscopy (STS) are employed to interrogate point and line defects in monolayer MoS2 grown on epitaxial graphene (EG) at the atomic scale. Five types of point defects are observed with the majority species showing apparent structures that are consistent with vacancy and interstitial models. The total defect density is observed to be lower than MoS2 grown on other substrates, and is likely attributed to the van der Waals epitaxy of MoS2 on EG. Grain boundaries (GBs) with 30° and 60° tilt angles resulting from the rotational commensurability of MoS2 on EG are more easily resolved by STM than atomic force microscopy at similar scales due to the enhanced contrast from their distinct electronic states. For example, band gap reduction to ~0.8 eV and ~0.5 eV is observed with STS for 30° and 60° GBs, respectively. In addition, atomic resolution STM images of these GBs are found to agree well with proposed structure models. This work offers quantitative insight into the structure and properties of common defects in MoS2, and suggests pathways for tailoring the performance of MoS2/graphene heterostructures via defect engineering.

description: Data on residential renovations are crucial for assessing their energy efficiency and living conditions of residents. Based on the real estate register data in Slovenia, we have information about the year of construction of buildings, as well as the year of renovation of roofs, facades, windows, and installations. However, the data for the period after 2007, when the last real estate census was conducted, is incomplete. Moreover, official surveys also have very limited data on this topic. To get more detailed insights into the renovation procedures of Slovenian households, we conducted our own survey on a web panel, which provided insights into renovation characteristics not captured by existing data sources. This contribution compares survey data on renovations with registry data and attempts to evaluate the quality of survey data.

description: Modular data is the most significant invariant of a modular tensor category. We pursue an approach to the classification of modular data of modular tensor categories by building the modular $S$ and $T$ matrices directly from irreducible representations of $SL_2(\mathbb{Z}/n \mathbb{Z})$. We discover and collect many conditions on the $SL_2(\mathbb{Z}/n \mathbb{Z})$ representations to identify those that correspond to some modular data. To arrive at concrete matrices from representations, we also develop methods that allow us to select the proper basis of the $SL_2(\mathbb{Z}/n \mathbb{Z})$ representations so that they have the form of modular data. We apply this technique to the classification of rank-$6$ modular tensor categories, obtaining a classification up to modular data. Most of the calculations can be automated using a computer algebraic system, which can be employed to classify modular data of higher rank modular tensor categories.

description: We study the spreading of two mutually cooperative diseases on different network topologies, and with two microscopic realizations, both of which are stochastic versions of an SIR type model studied by us recently in mean field approximation. There it had been found that cooperativity can lead to first-order spreading/extinction transitions. However, due to the rapid mixing implied by the mean field assumption, first order transitions required non-zero initial densities of sick individuals. For the stochastic model studied here the results depend strongly on the underlying network. First order transitions are found when there are few short but many long loops: (i) No first order transitions exist on trees and on 2-d lattices with local contacts (ii) They do exist on Erdos-Renyi (ER) networks, on d-dimensional lattices with d >= 4, and on 2-d lattices with sufficiently long-ranged contacts; (iii) On 3-d lattices with local contacts the results depend on the microscopic details of the implementation; (iv) While single infected seeds can always lead to infinite epidemics on regular lattices, on ER networks one sometimes needs finite initial densities of infected nodes; (v) In all cases the first order transitions are actually "hybrid", i.e. they display also power law scaling usually associated with second order transitions. On regular lattices, our model can also be interpreted as the growth of an interface due to cooperative attachment of two species of particles. Critically pinned interfaces in this model seem to be in different universality classes than standard critically pinned interfaces in models with forbidden overhangs. Finally, the detailed results mentioned above hold only when both diseases propagate along the same network of links. If they use different links, results can be rather different in detail, but are similar overall.

Early-type dwarf galaxies with multicomponent stellar structure: Are they remnants of disc galaxies strongly transformed by their environment?

description: The surface brightness distribution of $\sim$30-40$\%$ of the early-type dwarf galaxies with $-18 \leq M_{B} \leq -15$ in the Virgo and the Coma clusters is fitted by models that include two structural components (Sèrsic + exponential) as for bright disc galaxies.The goal of the present study is to determine whether early-type dwarf galaxies with a two-component stellar structure in the Virgo and the Coma clusters are low-luminosity copies of bright disc galaxies or are the remnants of bright galaxies strongly transformed by cluster environmental effects.I analysed the location of bright disc galaxies and early-type dwarfs in the $r_{b,e}/h$- $n$ plane. The location in this plane of the two-component dwarf galaxies was compared with the remnants of tidally disrupted disc galaxies reported by numerical simulations. Bright unbarred disc galaxies show a strong correlation in the $r_{b,e}/h$-$n$ plane. Galaxies with larger Sèrsic shape parameters show a higher $r_{b,e}/h$ ratio. In contrast, two-component early-type dwarf galaxies do not follow the same correlation. A fraction ($\sim$55%) of them are located outside the locus defined in this plane by having 95$\%$ of bright disc galaxies. This distribution indicates that they are not a low-mass replica of bright disc galaxies. The different location in the $r_{b,e}/h$- $n$ plane of two-component early-type dwarfs and bright galaxies can be qualitatively explain whether the former are remnants of disc galaxies strongly transformed by tidal processes.The progenitors of $\sim$20-25% of early-type dwarf galaxies with $-18 \leq M_{B} \leq -15$ in the Virgo and Coma clusters could be bright disc galaxies transformed by effects of the environment. These tidally transformed galaxies can be selected according to their location in the $r_{b,e}/h$-$n$ plane.

description: Thin films of VO$_2$ on different substrates, Al$_2$O$_3$ and SiO$_2$/Si, have been prepared and characterized from room temperature up to 360 K. From the band structure in the rutile metallic phase and in the monoclinic insulating phase the optical properties are calculated and compared with reflection measurements as a function of temperatures. Various interband transitions can be assigned and compared with previous speculations. We extract the parameters of the metallic charge carriers that evolve upon crossing the insulator-to-metal phase transition and find effects by the substrate. The effect of electronic correlations becomes obvious at the phase transition.

description: It has been recently shown that non-Abelian defects with localized parafermion zero modes can arise in conventional Abelian fractional quantum Hall (FQH) states. Here we propose an alternate route to creating, manipulating, and measuring topologically protected degeneracies in bilayer FQH states coupled to superconductors, without the creation of localized parafermion zero modes. We focus mainly on electron-hole bilayers, with a $\pm 1/3$ Laughlin FQH state in each layer, with boundaries that are proximity-coupled to a superconductor. We show that the superconductor induces charge $2e/3$ quasiparticle-pair condensation at each boundary of the FQH state, and that this leads to (1) topologically protected degeneracies that can be measured through charge sensing experiments and (2) a fractional charge $2e/3$ AC Josephson effect. We demonstrate that an analog of non-Abelian braiding is possible, despite the absence of a localized zero mode. We discuss several practical advantages of this proposal over previous work, and also extensions to electron-electron bilayers at $ν= 2/3 + 1/3$ coupled to superconductivity, and to electron-hole bilayers with only interlayer tunneling.

description: We investigate the properties of a four-dimensional conformal field theory possessing a fermionic higher-spin current $Q_{α(2k) \dotα}$. Using a computational approach, we examine the number of independent tensor structures contained in the three-point correlation functions of two fermionic higher-spin currents with the conserved vector current $V_{m}$, and with the energy-momentum tensor $T_{m n}$. In particular, the $k = 1$ case corresponds to a "supersymmetry-like" current, that is, a fermionic conserved current with identical properties to the supersymmetry current which appears in $\mathcal{N} = 1$ superconformal field theories. However, we show that in general, the three-point correlation functions $\langle Q Q T\rangle $, $\langle \bar{Q} Q V\rangle $ and $\langle \bar{Q} Q T\rangle $ are not consistent with $\mathcal{N}=1$ supersymmetry

description: Active (i.e., self-propelled or swimming) particles moving through an isotropic fluid exhibit conventional diffusive behavior. We report anomalous diffusion of an active particle moving in an anisotropic, nematic background. Whilst the translational motion parallel to the nematic director shows ballistic behavior, the long-time transverse motion is super-diffusive, with an anomalous scaling $\propto t \ln t$ of the mean squared displacement with time $t$. This behavior is predicted by an analytical theory that we present here, and is corroborated by numerical simulation of active particle diffusion in a simple lattice model for a nematic liquid crystal. It is universal for any collection of self-propelled elements (e.g., bacteria or active rods) moving in a nematic background, provided only that the swimmers are sufficiently dilute that their interactions with each other can be neglected, and that they do not perform "hairpin" turns.

description: Email is one of the most widely used ways to communicate, with millions of people and businesses relying on it to communicate and share knowledge and information on a daily basis. Nevertheless, the rise in email users has occurred a dramatic increase in spam emails in recent years. Processing and managing emails properly for individuals and companies are getting increasingly difficult. This article proposes a novel technique for email spam detection that is based on a combination of convolutional neural networks, gated recurrent units, and attention mechanisms. During system training, the network is selectively focused on necessary parts of the email text. The usage of convolution layers to extract more meaningful, abstract, and generalizable features by hierarchical representation is the major contribution of this study. Additionally, this contribution incorporates cross-dataset evaluation, which enables the generation of more independent performance results from the model's training dataset. According to cross-dataset evaluation results, the proposed technique advances the results of the present attention-based techniques by utilizing temporal convolutions, which give us more flexible receptive field sizes are utilized. The suggested technique's findings are compared to those of state-of-the-art models and show that our approach outperforms them.

description: The fabrication of polylactic acid (PLA)-carbonated hydroxyapatite (cHAP) composite material from synthesised phase pure nano-cHAP and melted PLA by mechanical mixing at 220-235°C has been developed in this study. Topographical structuring of PLA-cHAP composite surfaces was performed by direct laser writing (DLW). Microstructured surfaces and the apatite distribution within the composite and formed grooves were evaluated by optical and scanning electron microscopies. The influence of the dopant concentration as well as the laser power and translation velocity on the composite surface morphology is discussed. The synthesis of carbonated hydroxyapatite (cHAP) nanocrystalline powders via wet chemistry approach from calcium acetate and diammonium hydrogen phosphate precursors together with crosslinking and complexing agents of polyethylene glycol, poly(vinyl alcohol) and triethanolamine is also reported. Thermal decomposition of the gels and formation of nanocrystalline cHAP were evaluated by thermal analysis, mass spectrometry and dilatometry measurements. The effect of organic additives on the formation and morphological features of cHAP was investigated. The phase purity and crystallinity of the carbonated apatite powders were evaluated by X-ray diffraction analysis and FT-IR spectroscopy.

description: Peripheral vascular disease has become a prevalent condition worldwide and its incidence is predicted to increase as the median age of the population rises. In patients with severe peripheral ischemia, surgical or percutaneous interventions are necessary, but these procedures are invasive and provide only short-term relief. New treatment approaches that use growth factors or stem cells to enhance revascularization of ischemic tissues have shown promise in healthy animal models of peripheral ischemia. However, they have not achieved consistent positive results in clinical trials. We have developed a preclinical rabbit model of hind limb ischemia that can be used to assess the effectiveness of angiogenic therapies in the presence of therapeutic resistance. Diabetic and non-diabetic models were compared based on their ability to limit vascular recovery. Using the optimized model, we tested a novel therapy that delivers growth factors along with the coreceptor syndecan-4 to overcome the disease state. With the addition of syndecan-4, we observed significant increases in vessel formation and a greater distribution of larger vessels in the thigh and foot. The delivery of the syndecan-4 coreceptor in conjunction with growth factors allowed us to circumvent the disease state and significantly improve vascular recovery. We also explored the use of mechanical forces to enhance therapies for ischemia using mesenchymal stem cells. Mesenchymal stem cells are an attractive stem cell type as they can be harvested from adult patients with relative ease. While it would be desirable to differentiate mesenchymal stem cells into vascular phenotypes for enhancing regeneration this has proven difficult to achieve in past studies. We used a high throughput screen combining shear stress, small molecule inhibitors and variations in substrate stiffness to find conditions that encouraged mesenchymal stem cell differentiation into endothelial cell phenotypes. We found that the use of shear forces alone increased transcription factor and vascular markers. Flow cytometry and a kinase inhibitor library screen showed vascular expression increased further with the addition of soft growth substrates and specific drug treatments. The studies performed in this thesis both move us closer to having effective, long-term, solutions for the treatment of peripheral ischemia in human patients.

description: The millisecond pulsars, old-recycled objects spinning with high frequency $\mathcal{O}$ (kHz) sustaining the deformation from their spherical shape, may emit gravitational waves (GW). These are one of the potential candidates contributing to the anisotropic stochastic gravitational-wave background (SGWB) observable in the ground-based GW detectors. Here, we present the results from a likelihood-based targeted search for the SGWB due to millisecond pulsars in the Milky Way, by analyzing the data from the first three observing runs of Advanced LIGO and Advanced Virgo detector. We assume that the shape of SGWB power spectra and the sky distribution is known \textit{a priori} from the population synthesis model. The information of the ensemble source properties, i.e., the in-band number of pulsars, $N_{\textrm{obs}}$ and the averaged ellipticity, $μ_ε$ is encoded in the maximum likelihood statistic. We do not find significant evidence for the SGWB signal from the considered source population. The best Bayesian upper limit with $95\%$ confidence for the parameters are $N_{\textrm{obs}}\leq8.8\times10^{4}$ and $μ_ε\leq1.4\times10^{-6}$, which is comparable to the bounds on mean ellipticity with the GW observations of the individual pulsars. Finally, we show that for the plausible case of $N_{\textrm{obs}}=40,000$, with the one year of observations, the one-sigma sensitivity on $μ_ε$ might reach $1.5\times10^{-7}$ and $4.1\times10^{-8}$ for the second-generation detector network having A+ sensitivity and third-generation detector network, respectively.

Photometrically-Classified Superluminous Supernovae from the Pan-STARRS1 Medium Deep Survey: A Case Study for Science with Machine Learning-Based Classification

description: With the upcoming Vera C.~Rubin Observatory Legacy Survey of Space and Time (LSST), it is expected that only $\sim 0.1\%$ of all transients will be classified spectroscopically. To conduct studies of rare transients, such as Type I superluminous supernovae (SLSNe), we must instead rely on photometric classification. In this vein, here we carry out a pilot study of SLSNe from the Pan-STARRS1 Medium-Deep Survey (PS1-MDS) classified photometrically with our SuperRAENN and Superphot algorithms. We first construct a sub-sample of the photometric sample using a list of simple selection metrics designed to minimize contamination and ensure sufficient data quality for modeling. We then fit the multi-band light curves with a magnetar spin-down model using the Modular Open-Source Fitter for Transients (MOSFiT). Comparing the magnetar engine and ejecta parameter distributions of the photometric sample to those of the PS1-MDS spectroscopic sample and a larger literature spectroscopic sample, we find that these samples are overall consistent, but that the photometric sample extends to slower spins and lower ejecta masses, which correspond to lower luminosity events, as expected for photometric selection. While our PS1-MDS photometric sample is still smaller than the overall SLSN spectroscopic sample, our methodology paves the way to an orders-of-magnitude increase in the SLSN sample in the LSST era through photometric selection and study.

description: Let $K$ be an infinite field and let $m_1,\ldots,m_n$ be a generalized arithmetic sequence of positive integers, i.e., there exist $h, d, m_1 \in\mathbb{Z}^+$ such that $m_i = h m_1 + (i-1)d$ for all $i \in \{2,\ldots,n\}$. We consider the projective monomial curve $\mathcal C\subset \mathbb{P}^{n}_{K}$ parametrically defined by $$x_1=s^{m_1}t^{m_n-m_1},\dots,x_{n-1}=s^{m_{n-1}}t^{m_n-m_{n-1}},x_n=s^{m_n},x_{n+1}=t^{m_n}.$$ In this work, we characterize the Cohen-Macaulay and Koszul properties of the homogeneous coordinate ring $K[\mathcal C]$ of $\mathcal C$. Whenever $K[\mathcal C]$ is Cohen-Macaulay we also obtain a formula for its Cohen-Macaulay type. Moreover, when $h$ divides $d$, we obtain a minimal Gröbner basis $\mathcal G$ of the vanishing ideal of $\mathcal C$ with respect to the degree reverse lexicographic order. From $\mathcal G$ we derive formulas for the Castelnuovo-Mumford regularity, the Hilbert series and the Hilbert function of $K[\mathcal C]$ in terms of the sequence.
Generalized Bloch's theorem for viscous metamaterials: Dispersion and effective properties based on frequencies and wavenumbers that are simultaneously complex

description: It is common for dispersion curves of damped periodic materials to be based on real frequencies versus complex wavenumbers or, conversely, real wavenumbers versus complex frequencies. The former condition corresponds to harmonic wave motion where a driving frequency is prescribed and where attenuation due to dissipation takes place only in space alongside spatial attenuation due to Bragg scattering. The latter condition, on the other hand, relates to free wave motion admitting attenuation due to energy loss only in time while spatial attenuation due to Bragg scattering also takes place. Here, we develop an algorithm for 1D systems that provides dispersion curves for damped free wave motion based on frequencies and wavenumbers that are permitted to be simultaneously complex. This represents a generalized application of Bloch's theorem and produces a dispersion band structure that fully describes all attenuation mechanisms, in space and in time. The algorithm is applied to a viscously damped mass-in-mass metamaterial exhibiting local resonance. A frequency-dependent effective mass for this damped infinite chain is also obtained.
