description: In measurement-based quantum computing (MBQC), computation is carried out by a sequence of measurements and corrections on an entangled state. Flow, and related concepts, are powerful techniques for characterising the dependence of the corrections on previous measurement results. We introduce flow-based methods for quantum computation with continuous-variable graph states, which we call CV-flow. These are inspired by, but not equivalent to, the notions of causal flow and g-flow for qubit MBQC. We also show that an MBQC with CV-flow approximates a unitary arbitrarily well in the infinite-squeezing limit, addressing issues of convergence which are unavoidable in the infinite-dimensional setting. In developing our proofs, we provide a method for converting a CV-MBQC computation into a circuit form, analogous to the circuit extraction method of Miyazaki et al, and an efficient algorithm for finding CV-flow when it exists based on the qubit version by Mhalla and Perdrix. Our results and techniques naturally extend to the cases of MBQC for quantum computation with qudits of prime local dimension.

description: This is number one of 42 preservation briefs prepared by the Technical Preservation Services of the National Park Service. This brief focuses on the cleaning and ware-repellent treatments for historic masonry buildings. A well-planned cleaning project is an essential step in preserving, rehabilitating or restoring a historic masonry building. Proper cleaning methods and coating treatments, when determined necessary for the preservation of the masonry, can enhance the aesthetic character as well as the structural stability of a historic building. Removing years of accumulated dirt, pollutant crusts, stains, graffiti or paint, if done with appropriate caution, can extend the life and longevity of the historic resource. Cleaning that is carelessly or insensitively prescribed or carried out by inexperienced workers can have the opposite of the intended effect. It may scar the masonry permanently, and may actually result in hastening deterioration by introducing harmful residual chemicals and salts into the masonry or causing surface loss. Using the wrong cleaning method or using the right method incorrectly, applying the wrong kind of coating or applying a coating that is not needed can result in serious damage, both physically and aesthetically, to a historic masonry building. Cleaning a historic masonry building should always be done using the gentlest means possible that will clean, but not damage the building. It should always be taken into consideration before applying a water-repellent coating or a waterproof coating to a historic masonry building whether it is really necessary and whether it is in the best interest of preserving the building.

description: We show that the one-dimensional (1D) two-fluid model (TFM) for stratified flow in channels and pipes (in its incompressible, isothermal form) satisfies an energy conservation equation, which arises naturally from the mass and momentum conservation equations that constitute the model. This result extends upon earlier work on the shallow water equations (SWE), with the important difference that we include non-conservative pressure terms in the analysis, and that we propose a formulation that holds for ducts with an arbitrary cross-sectional shape, with the 2D channel and circular pipe geometries as special cases. The second novel result of this work is the formulation of a finite volume scheme for the TFM that satisfies a discrete form of the continuous energy equation. This discretization is derived in a manner that runs parallel to the continuous analysis. Due to the non-conservative pressure terms it is essential to employ a staggered grid, which requires careful consideration in defining the discrete energy and energy fluxes, and the relations between them and the discrete model. Numerical simulations confirm that the discrete energy is conserved.
Eccentricity evolution in hierarchical triple systems with eccentric outer binaries

description: We develop a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular, while the outer one is eccentric. We consider coplanar systems with well separated components and comparable masses. The derivation of short period terms is based on an expansion of the rate of change of the Runge-Lenz vector. Then, the short period terms are combined with secular terms, obtained by means of canonical perturbation theory. The validity of the theoretical equations is tested by numerical integrations of the full equations of motion.

Mitigating Non-Tariff Measures in Agriculture: Preferential Trade Agreements and Conversations
Creators: name: Yeung, May
Publisher: name: The School of Public Policy Publications
Year: 2022

description: Regulatory divergence between countries is creating barriers to market access in international agri-food trade, becoming what are known as non-tariff measures (NTMs). NTMs create friction in international trade, increasing fulfillment costs and, if sufficiently burdensome, pose a very real threat to global food security. More countries, including Canada, are turning to preferential trade agreements (PTAs) to liberalize trade. The Comprehensive Economic and Trade Agreement (CETA) between Canada and the European Union was heralded as comprehensive in its coverage, reducing or eliminating tariffs in virtually all aspects of trade. Overall bilateral trade has increased since CETA came into force but not for many of Canada’s agri-food exporters. CETA’s tariff-focused agenda did little to mitigate the NTMs impeding many Canadian agri-food exports. NTMs are not unique to Canada-EU trade. They are an increasing factor impeding world food trade as more governments are basing policy decisions on ideological or political factors rather than sound science. As a result, regulatory divergence in NTMs is widening among a greater number of countries. The agri-food trade system becomes less predictable, riskier and more volatile. For international trade, it has been described as a slow death by 1,000 regulations. The only means to address regulatory divergence is to facilitate regulatory convergence. This is not an easy task given the number of multi-disciplinary stakeholders involved, both domestic and international. While PTAs are not well equipped to legislatively force convergence, they do provide informal and formal opportunities for building networks, strengthening relationships and opening communication channels that can foster and facilitate regulatory convergence. Every opportunity to do so, whether bilaterally, through PTAs or multilaterally, must be taken advantage of.

description: BACKGROUND: Because retinal and cerebral arterioles share similar pathologic processes, retinal microvascular changes are expected to be markers of cerebral small vessel disease (SVD). To better understand the role of SVD in cognitive function, we investigated the relationship between retinal microvascular abnormalities and longitudinal changes in cognitive function in a community-based study.

METHODS: A total of 803 participants underwent 4 cognitive assessments between 1990-1992 and 2004-2006, using the Word Fluency (WF) test, Digit Symbol Substitution (DSS), and Delayed Word Recall as well as retinal photography in 1993-1995. Covariate adjusted random effects linear models for repeated measures were used to determine the associations of cognitive change with specific retinal vascular abnormalities.

RESULTS: Individuals with retinopathy showed declines in executive function and psychomotor speed, with 1) an average decline in WF of -1.64 words per decade (95% confidence interval [CI] -3.3, -0.02) compared to no decline in those without retinopathy +0.06 (95% CI -0.6, 0.8) and 2) a higher frequency of rapid decliners on the DSS test.

CONCLUSION: Signs of retinal vascular changes, as markers of the cerebral microvasculature, are associated with declines in executive function and psychomotor speed, adding to the growing evidence for the role of microvascular disease in cognitive decline in the elderly.
A Guaranteed Basic Income for Canadians: Off the Table or Within Reach?

description: Pilot projects in the past that have experimented with a Guaranteed Basic Income (GBI) in Manitoba and Ontario, and a recent study of the feasibility of a GBI in British Columbia, indicate that provinces are not in an ideal position to successfully implement an affordable and effective GBI. However, a GBI implemented by the federal government, financed by eliminating the GST credit and lowering personal tax exemptions, could be both effective and affordable. It could also do so without requiring the elimination of those provincial social assistance programs that are more deeply targeted toward people’s needs. By using its revenue powers, the federal government could create more fiscal capacity for the provinces to provide other cash and in-kind social supports, allowing for greater provincial benefit targeting. The federal government’s centrality in designing and implementing tax structures and collecting tax revenue make it singularly suitable for administering and delivering a GBI. Financing the GBI by eliminating the modest GST credit and lowering the current basic personal income tax exemption could provide a significant reduction in the rate, depth and intensity of poverty in Canada, without imposing an excessive tax burden on Canadians. If provinces use the GBI as a replacement for certain less-targeted provincial social assistance income transfers, the freed-up payments and reduced caseloads could also allow provinces to target more effectively those needs not addressed by the GBI. The recent COVID-19 pandemic exposed longstanding gaps in Canada’s income- support frameworks, with lower-income workers facing exceptional economic vulnerability. At the same time, the Canadian Emergency Response Benefit proved edifying in terms of how to best design a basic-income program. In addition, the federal government’s experiences with the poverty-reducing impacts of the Canada Child Benefit, the Old Age Supplement and the Guaranteed Income Supplement have moved Canada closer than ever to a workable GBI. While it comes with additional costs, those costs will be less burdensome than many GBI skeptics might believe. They must also be put into perspective, by comparing them against the costs of current and, in many cases ineffective income transfers and, just as importantly, against the human cost of leaving more Canadians living in poverty.

Gait and Cognition: Exploring Cognition and Dual-task Costs in a Group of Community Dwelling Alzheimer’s Disease Patients over 6 Months
Creators: Davis, Christopher MJ
Publisher: name: University of Alberta Library
Year: 2022

Alzheimer’s disease is a progressive neurological disorder resulting in cognitive decline affecting many activities of daily living including gait. Many tools exist to monitor AD progression, including cognitive examinations, and functional tests of mobility. The purpose of the present study is to analyse a diverse group of 18 community dwelling AD patients at baseline, 3 months, and 6 months to monitor changes to select cognitive and functional tests; to examine dual-task costs to specific gait parameters; and examine possible correlations between cognitive scores and dual-task costs to gait. Three cognitive tests were used: Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and two subsets of the Cognigram Cogstate Brief Battery (CBB1 and CBB2). Gait was assessed using a GAITRite electronic walkway under single-task and dual-task conditions. Previous research has identified some of the costs to gait due to dual-tasking in cognitively impaired older adults compared to healthy older adults includes: decreases to gait speed, cadence, stride length; increases to stride time, and stride time variability. In the present study, these measures were assessed as a percentage change between their preferred walk (PW) and their dual-task walk (DTW); this percentage change while dual-tasking is referred to as their dual-task costs (DTC).

Results: dual-task costs to gait and cognitive data show no significant change over the 6 month time period. Correlation coefficients between cognition and dual-task costs showed mixed results, suggesting a partial relationship between cognitive scores and some gait measures of dual-task costs, with the MoCA being most highly correlated. The animal fluency dual-task created statistically significant changes to all gait measures including means and coefficients of variation; all these changes were associated with poorer gait kinematics. Some gait variables showed consistent results amongst participants, while others showed high ranges of variability, expressed through the range of standard deviations. High levels of variability may suggest that those measures are more sensitive to differences between participants, and may therefore make them valuable measures to explore more thoroughly in the future. Gait variability DTCs were not correlated with any cognitive tests.

description: Background: The neutron skin thickness $R_{\rm skin}^{\rm PV}$ of PREX-II is presented in Phys. Rev. Lett. {\bf 126}, 172502 (2021). The reaction cross section $σ_R$ is useful to determine the matter radius $R_m$ and $R_{\rm skin}$. For proton scattering, the reaction cross section $σ_R$ are available for $E_{\rm in} > 400$ MeV. Method and results: We determine $R_n^{\rm exp}=5.727 \pm 0.071$ fm and $R_m^{\rm exp}=5.617 \pm 0.044$ fm from $R_p^{\rm exp}$ = 5.444 fm and $R_{\rm skin}^{\rm PV}$. The $R_p^{\rm GHFB}$ calculated with D1S-GHFB with the angular momentum projection (AMP). agrees with $R_p^{\rm exp}$. The neutron density calculated with GHFB+AMP is scaled so as to $R_n^{\rm scaling}=5.727$ fm. The Love-Franey $t$-matrix model with the scaled densities reproduces the data on $σ_R$. Aim: Our aim is to find the $σ_R$ of proton scattering consistent with $R_{\rm skin}^{\rm PV}$. Conclusion: The $σ_R$ of proton scattering consistent with $R_{\rm skin}^{\rm PV}$ are $σ_R^{\rm exp}$ at $E_{\rm in} = 534.1, 549, 806$ MeV.

This Preservation Brief is intended to assist owners, architects, and planning officials in answering such questions about how to evaluate and preserve the character of historic storefronts. In so doing, it not only addresses the basic design issues associated with storefront rehabilitation, but recommends preservation treatments as well. Finally, although the Brief focuses on storefront rehabilitation, it is important to review this specific work in the broader context of preserving and maintaining the overall structure. Money spent on storefront rehabilitation may be completely wasted if repair and maintenance problems on the rest of the building are neglected.

description: BACKGROUND: Constraint-induced movement therapy (CIMT) is among the most developed training approaches for motor restoration of the upper extremity (UE).

METHODS: Very Early Constraint-Induced Movement during Stroke Rehabilitation (VECTORS) was a single-blind phase II trial of CIMT during acute inpatient rehabilitation comparing traditional UE therapy with dose-matched and high-intensity CIMT protocols. Participants were adaptively randomized on rehabilitation admission, and received 2 weeks of study-related treatments. The primary endpoint was the total Action Research Arm Test (ARAT) score on the more affected side at 90 days after stroke onset. A mixed model analysis was performed.

RESULTS: A total of 52 participants (mean age 63.9 +/- 14 years) were randomized 9.65 +/- 4.5 days after onset. Mean NIHSS was 5.3 +/- 1.8; mean total ARAT score was 22.5 +/- 15.6; 77% had ischemic stroke. Groups were equivalent at baseline on all randomization variables. As expected, all groups improved with time on the total ARAT score. There was a significant time x group interaction (F = 3.1, p < 0.01), such that the high intensity CIT group had significantly less improvement at day 90. No significant differences were found between the dose-matched CIMT and control groups at day 90. MRI of a subsample showed no evidence of activity-dependent lesion enlargement.

CONCLUSION: Constraint-induced movement therapy (CIMT) was equally as effective but not superior to an equal dose of traditional therapy during inpatient stroke rehabilitation. Higher intensity CIMT resulted in less motor improvement at 90 days, indicating an inverse dose-response relationship. Motor intervention trials should control for dose, and higher doses of motor training cannot be assumed to be more beneficial, particularly early after stroke.

description: OBJECTIVE: To determine factors associated with baseline neurocognitive performance in HIV-infected participants enrolled in the Strategies for Management of Antiretroviral Therapy (SMART) neurology substudy.

METHODS: Participants from Australia, North America, Brazil, and Thailand were administered a 5-test neurocognitive battery. Z scores and the neurocognitive performance outcome measure, the quantitative neurocognitive performance z score (QNPZ-5), were calculated using US norms. Neurocognitive impairment was defined as z scores <-2 in two or more cognitive domains. Associations of test scores, the QNPZ-5, and impairment with baseline factors including demographics and risk factors for HIV-associated dementia (HAD) and cardiovascular disease (CVD) were determined in multiple regression.

RESULTS: The 292 participants had a median CD4 cell count of 536 cells/mm(3), 88% had an HIV viral load < or =400 copies/mL, and 92% were taking antiretrovirals. Demographics, HIV, and clinical factors differed between locations. The mean QNPZ-5 score was -0.72; 14% of participants had neurocognitive impairment. For most tests, scores and z scores differed significantly between locations, with and without adjustment for age, sex, education, and race. Prior CVD was associated with neurocognitive impairment. Prior CVD, hypercholesterolemia, and hypertension were associated with poorer neurocognitive performance but conventional HAD risk factors and the CNS penetration effectiveness rank of antiretroviral regimens were not.

CONCLUSIONS: In this HIV-positive population with high CD4 cell counts, neurocognitive impairment was associated with prior CVD. Lower neurocognitive performance was associated with prior CVD, hypertension, and hypercholesterolemia, but not conventional HAD risk factors. The contribution of CVD and cardiovascular risk factors to the neurocognition of HIV-positive populations warrants further investigation.

description: The entanglement entropy for interfaces and junctions of two-dimensional CFTs is evaluated on holographically dual half-BPS solutions to six-dimensional Type 4b supergravity with m anti-symmetric tensor supermultiplets. It is shown that the moduli space for an N-junction solution projects to N points in the Kaehler manifold SO(2,m)/( SO(2) x SO(m)). For N=2 the interface entropy is expressed in terms of the central charge and Calabi's diastasis function on SO(2,m)/(SO(2) x SO(m)), thereby lending support from holography to a proposal of Bachas, Brunner, Douglas, and Rastelli. For N=3, the entanglement entropy for a 3-junction decomposes into a sum of diastasis functions between pairs, weighed by combinations of the three central charges, provided the flux charges are all parallel to one another or, more generally, provided the space of flux charges is orthogonal to the space of unattracted scalars. Under similar assumptions for N>3, the entanglement entropy for the N-junction solves a variational problem whose data consist of the N central charges, and the diastasis function evaluated between pairs of N asymptotic AdS_3 x S^3 regions.

description: OBJECTIVE: Prior research suggests an acutely elevated risk of myocardial infarction and sudden cardiac death in the hour after coffee intake. However, the risk of ischemic stroke associated with transient exposure to coffee remains unclear. We hypothesized that caffeine intake is associated with a transiently increased risk of ischemic stroke.

METHODS: In this multicenter case-crossover study, we interviewed 390 subjects (209 men, 181 women) between January 2001 and November 2006 a median of 3 days after acute ischemic stroke. Each subject's coffee consumption in the hour before stroke symptoms was compared with his or her usual frequency of consumption in the prior year.

RESULTS: Of the 390 subjects, 304 (78%) drank coffee in the prior year, 232 within 24 hours and 35 within 1 hour of stroke onset. The relative risk (RR) of stroke in the hour after consuming coffee was 2.0 (95% confidence interval [CI], 1.4-2.8; p < 0.001). There was no apparent increase in risk in the hour following consumption of caffeinated tea (RR = 0.9, 95% CI 0.4-2.0; p = 0.85) or cola (RR = 1.0, 95% CI 0.4-2.4; p = 0.95). The association between ischemic stroke in the hour after coffee consumption was only apparent among those consuming ≤1 cup per day but not for patients who consumed coffee more regularly (p for trend = 0.002). Relative risks remained similar when the sample was restricted to those who were not simultaneously exposed to other potential triggers and the results remained significant after stratifying by time of day.

CONCLUSION: Coffee consumption transiently increases the risk of ischemic stroke onset, particularly among infrequent drinkers.

Disinformation and Russia-Ukrainian War on Canadian Social Media
Creators: name: Boucher, Jean-Christophe

description: The Russia-Ukrainian war has led to a large disinformation campaign, largely spread through social media. Canada has been a target of these influence campaigns to affect Canadian public opinions. In this policy brief, we venture to examine the prevalence of pro-Russian narratives on Canadian social media as well as identify major influencers creating and spreading such narratives. Additionally, using artificial intelligence, we seek to examine the reach and nature of pro-Russian disinformation narratives. Our research team has been collecting more than 6.2 million Tweets globally since January 2022 to monitor and measure Russian influence operations on social media. We find that pro-Russian narratives promoted in the Canadian social media ecosystem on twitter are divided into two large communities: 1) accounts influenced by sources from the United States and 2) those largely influenced by sources from international sources from Russia, Europe, and China. First, pro-Russian discourse on Canadian Twitter blames NATO for the conflict suggesting that Russia’s invasion was a result of NATO’s expansionism or aggressive intentions toward Russia. In this context, pro-Russian propaganda argues that the West has no moral high ground to condemn the invasion and nations such as Canada, the US, and the UK are trying to force Europe into this conflict to benefit materially. Second, it is suggested that Western nations are propping up fascists in Ukraine, thus justifying Russia’s actions. Thirdly, pro-Russian narrative attempts to amplify mistrust of democratic institutions, be it the media, international institutions, or the Liberal government. Faced with the challenges associated with foreign interference, it is important to gain a deeper understanding of the spread of disinformation in Canada.

description: OBJECTIVE: Prior studies have shown improved neurocognition with initiation of antiretroviral treatment (ART) in HIV. We hypothesized that stopping ART would be associated with poorer neurocognitive function.

METHODS: Neurocognitive function was assessed as part of ACTG 5170, a multicenter, prospective observational study of HIV-infected subjects who elected to discontinue ART. Eligible subjects had CD4 count >350 cells/mm(3), had HIV RNA viral load <55,000 cp/mL, and were on ART (>or=2 drugs) for >or=6 months. Subjects stopped ART at study entry and were followed for 96 weeks with a neurocognitive examination.

RESULTS: A total of 167 subjects enrolled with a median nadir CD4 of 436 cells/mm(3) and 4.5 median years on ART. Significant improvements in mean neuropsychological scores of 0.22, 0.39, 0.53, and 0.74 were found at weeks 24, 48, 72, and 96 (all p < 0.001). In the 46 subjects who restarted ART prior to week 96, no significant changes in neurocognitive function were observed.

CONCLUSION: Subjects with preserved immune function found that neurocognition improved significantly following antiretroviral treatment (ART) discontinuation. The balance between the neurocognitive cost of untreated HIV viremia and the possible toxicities of ART require consideration.

CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that discontinuing ART is associated with an improvement in 2 neuropsychological tests (Trail-Making Test A & B and the Wechsler Adult Intelligence Scale-Revised Digit Symbol subtest) for up to 96 weeks. Resuming ART was not associated with a decline in these scores for up to 45 weeks.
Community-Based Environmental Monitoring (CBEM) for Meaningful Incorporation of Indigenous and Local Knowledge Within the Context of the Canadian Northern Corridor Program

description: Meaningful incorporation of Indigenous and local knowledge (ILK) in climate change mitigation and adaptation efforts is key to accelerating effective action plans. This study argues that community-based environmental monitoring (CBEM), if done properly, can be more effective in incorporating ILK than environmental impact and monitoring based only on Western science. The paper examines successful elements, benefits, challenges and limitations in the existing CBEM studies that incorporate ILK to recognize how to design comprehensive CBEM policy for large-scale infrastructure projects such as the Canadian Northern Corridor (CNC) concept. Based on a proposed framework for CBEM implementation (CBEM-IF), the study examines three Canadian CBEM case studies: berry pollution monitoring (AB), water quality monitoring (AB, BC, NWT, NT, SK and YT) and caribou monitoring (QC and NL), to evaluate lessons learned and to inform future CNC policy development. This study illustrates how knowledge co-production provides more opportunities for actions in sustainable development and incorporates emotional and spiritual components that entail different conceptualizations of human-nature connectedness. CBEM facilitates the incorporation of ILK and science, engages community members in the monitoring process and produces research outcomes which stakeholders perceive as more legitimate and relevant. CBEM can be a powerful tool in land-use conflict resolution, and it represents an inexpensive approach to monitoring the Arctic and near- North. Indigenous leadership, technology incorporation and equal partnership with communities, and availability of institutional guidelines were identified as required to enable the proper implementation of CBEM programs within the CNC. However, certain limitations of CBEM include lack of policy and guidelines; high reliance on volunteers; lack of standardized methods; focus on specific types of a landscape; general issues with TEK incorporation into science; and policy issues due to the incommensurability of Western science and the ILK epistemologies. Such challenges can be generalized as technical, organizational, financial and environmental issues and can be addressed by applying successful elements from previous international and Canadian CBEM studies. The authors suggest a series of policy recommendations to enable the implementation of CBEM as a means for meaningful incorporation of ILK on sustainable development projects and the CNC.

A general notion of uniform ellipticity and the regularity of the stress field for elliptic equations in divergence form

description: For solutions of ${\rm div}\,(DF(Du))=f$ we show that the quasiconformality of $z\mapsto DF(z)$ is the key property leading to the Sobolev regularity of the stress field $DF(Du)$, in relation with the summability of $f$. This class of nonlinearities encodes in a general way the notion of uniform ellipticity and encompasses all known instances where the stress field is known to be Sobolev regular. We provide examples showing the optimality of this assumption and present three applications: the study of the strong locality of the operator ${\rm div}\,(DF(Du))$, a nonlinear Cordes condition for equations in divergence form, and some partial results on the $C^{p'}$-conjecture.

Holographic Entanglement Entropy from 2d CFT: Heavy States and Local Quenches

description: We consider the entanglement entropy in 2d conformal field theory in a class of excited states produced by the insertion of a heavy local operator. These include both high-energy eigenstates of the Hamiltonian and time-dependent local quenches. We compute the universal contribution from the stress tensor to the single interval Renyi entropies and entanglement entropy, and conjecture that this dominates the answer in theories with a large central charge and a sparse spectrum of low-dimension operators. The resulting entanglement entropies agree precisely with holographic calculations in three-dimensional gravity. High-energy eigenstates are dual to microstates of the BTZ black hole, so the corresponding holographic calculation is a geodesic length in the black hole geometry; agreement between these two answers demonstrates that entanglement entropy thermalizes in individual microstates of holographic CFTs. For local quenches, the dual geometry is a highly boosted black hole or conical defect. On the CFT side, the rise in entanglement entropy after a quench is directly related to the monodromy of a Virasoro conformal block.

description: In this paper, we prove that the class of all special Gelfand--Dorfman algebras (GD-algebras) is closed with respect to homomorphisms and thus forms a variety. We also prove that every 2-dimensional GD-algebra is special. For the latter, we give a technical method to find all special identities of GD-algebras and compute the degree 6 component of the Gröbner basis for the shuffle operad constructed on the symmetric operad governing the class of GD-algebras.

description: Finding the right organizational structure to govern local communities is a long-standing concern amongst municipal decision-makers. Canada provides a range of local governance arrangements, including service cooperation, single-tier and two-tier models. These types of arrangements have implications for how a municipality is governed and financed. Underlying these concerns, are factors such as local identity, culture and values.

description: This article considers non-stationary incompressible linear fluid equations in a moving domain. We demonstrate the existence and uniqueness of an appropriate weak formulation of the problem by making use of the theory of time-dependent Bochner spaces. It is not possible to directly apply established evolving Hilbert space theory due to the incompressibility constraint. After we have established the well-posedness, we derive and analyse a first order time discretisation of the system.
