The Mediterranean diet pattern as a therapeutic approach for colitis
Creators: name: Haskey, Natasha
Publisher: name: University of British Columbia
Year: 2022

description: There is growing appreciation that the interaction between diet, the gut microbiota and the immune system contribute to the development and progression of chronic diseases like inflammatory bowel disease (IBD). Various types of dietary fat, independent of total fat content, uniquely influence intestinal inflammation, metabolism, and host-microbe dynamics. The Mediterranean Diet Pattern (MDP) is a health-promoting diet containing approximately 40% total fat. It is unknown if the blend of fats found in the MDP contributes to its beneficial health effects or could benefit patients living with ulcerative colitis (UC). For the experimental study, mice deficient in the mucin 2 gene (muc2-/-) were weaned to 40% fat, isocaloric, and isonitrogenous diets. We sought to clarify the effects of the MD fat blend on colitis by studying dietary fats in isolation from each other and a combination like the blend found in the MDP. We compared the MD fat blend (high monounsaturated fatty acids (MUFA), 2:1 n-6:n-3 polyunsaturated fatty acids (PUFA) and moderate saturated fat acids (SFA)) to diets composed of corn oil (CO, n-6 PUFA), olive oil (OO, high MUFA) or milk fat (MF, SFA) on spontaneous colitis development in Muc2-/- mice. The MD resulted in lower clinical and histopathological scores and induced tolerogenic CD103+CD11b+ dendritic cells, Th22 and IL-17+IL-22+ cells necessary for intestinal barrier repair. The MD was associated with beneficial microbes, and higher cecal acetic acid levels negatively correlated with colitogenic microbes like Akkermansia muciniphila. In contrast, CO showed a higher prevalence of mucin-degraders, including A. muciniphila and Enterobacteriaceae, which have been associated with colitis. For the clinical study, adult patients with quiescent UC were randomized to follow a MDP or Canadian habitual diet (CHD) for 12 weeks. The MDP resulted in reduced disease activity, symptoms, and inflammation-related biomarkers. Food components (fibre, dairy, olive oil and plant-based foods) commonly consumed in a MDP were positively associated with bacteria that produce metabolites related to health (Ruminococcus bromii, Flavonifractor plautii and Lactococcus lactis). Our findings suggest that the MDP could be utilized as adjunctive therapy to manage UC.

description: This note treats a simple minded question: what does a typical random matrix range look like? We study the relationship between various modes of convergence for tuples of operators, on the one hand, and continuity of matrix ranges with respect to the Hausdorff metric, on the other. In particular, we show that the matrix range of a tuple generating a continuous field of C*-algebras is continuous in the sense that every level is continuous in the Hausdorff metric. Using this observation together with known results on strong convergence in distribution of matrix ensembles, we identify the limit matrix ranges to which the matrix ranges of independent Wigner or Haar ensembles converge.

description: Multistage stochastic programs can be approximated by restricting policies to follow decision rules. Directly applying this idea to problems with integer decisions is difficult because of the need for decision rules that lead to integral decisions. In this work, we introduce Lagrangian dual decision rules (LDDRs) for multistage stochastic mixed-integer programming (MSMIP) which overcome this difficulty by applying decision rules in a Lagrangian dual of the MSMIP. We propose two new bounding techniques based on stagewise (SW) and nonanticipative (NA) Lagrangian duals where the Lagrangian multiplier policies are restricted by LDDRs. We demonstrate how the solutions from these duals can be used to drive primal policies. Our proposal requires fewer assumptions than most existing MSMIP methods. We compare the theoretical strength of the restricted duals and show that the restricted NA dual can provide relaxation bounds at least as good as the ones obtained by the restricted SW dual. In our numerical study on two problem classes, one traditional and one novel, we observe that the proposed LDDR approaches yield significant optimality gap reductions compared to existing general-purpose bounding methods for MSMIP problems.

description: We study the steady flow properties of different three-dimensional aqueous foams in a wide gap Couette geometry. From local velocity measurements through Magnetic Resonance Imaging techniques and from viscosity bifurcation experiments, we find that these foams do not exhibit any observable signature of shear banding. This contrasts with two previous results (Rodts et al., Europhys. Lett., 69 (2005) 636 and Da Cruz et al., Phys. Rev. E, 66 (2002) 051305); we discuss possible reasons for this dicrepancy. Moreover, the foams we studied undergo steady flow for shear rates well below the critical shear rate recently predicted (Denkov et al., Phys. Rev. Lett., 103 (2009) 118302). Local measurements of the constitutive law finally show that these foams behave as simple Herschel-Bulkley yield stress fluids.

description: The capacity of the Gaussian cognitive interference channel, a variation of the classical two-user interference channel where one of the transmitters (referred to as cognitive) has knowledge of both messages, is known in several parameter regimes but remains unknown in general. In this paper we provide a comparative overview of this channel model as we proceed through our contributions: we present a new outer bound based on the idea of a broadcast channel with degraded message sets, and another series of outer bounds obtained by transforming the cognitive channel into channels with known capacity. We specialize the largest known inner bound derived for the discrete memoryless channel to the Gaussian noise channel and present several simplified schemes evaluated for Gaussian inputs in closed form which we use to prove a number of results. These include a new set of capacity results for the a) "primary decodes cognitive" regime, a subset of the "strong interference" regime that is not included in the "very strong interference" regime for which capacity was known, and for the b) "S-channel" in which the primary transmitter does not interfere with the cognitive receiver. Next, for a general Gaussian cognitive interference channel, we determine the capacity to within one bit/s/Hz and to within a factor two regardless of channel parameters, thus establishing rate performance guarantees at high and low SNR, respectively. We also show how different simplified transmission schemes achieve a constant gap between inner and outer bound for specific channels. Finally, we numerically evaluate and compare the various simplified achievable rate regions and outer bounds in parameter regimes where capacity is unknown, leading to further insight on the capacity region of the Gaussian cognitive interference channel.

description: On $(X,ω)$ compact Kähler manifold, given a model type envelope $ψ\in PSH(X,ω)$ (i.e. a singularity type) we prove that the Monge-Ampère operator is an homeomorphism between the set of $ψ$-relative finite energy potentials and the set of $ψ$-relative energy measures endowed with their strong topologies given as the coarsest refinements of the weak topologies such that the relative energies become continuous. Moreover, given a totally ordered family $\mathcal{A}$ of model type envelopes with positive total mass representing different singularities types, the sets $X_{\mathcal{A}}, Y_{\mathcal{A}}$ given respectively as the union of all $ψ$-relative finite energy potentials and of all $ψ$-relative finite energy measures varying $ψ\in\overline{\mathcal{A}}$ have two natural strong topologies which extends the strong topologies on each component of the unions. We show that the Monge-Ampère operator produces an homeomorphism between $X_{\mathcal{A}}$ and $Y_{\mathcal{A}}$. As an application we also prove the strong stability of a sequence of solutions of prescribed complex Monge-Ampère equations when the measures have uniformly $L^{p}$-bounded densities for $p>1$ and the prescribed singularities are totally ordered.

description: In previous work we established a multilinear duality and factorisation theory for norm inequalities for pointwise weighted geometric means of positive linear operators defined on normed lattices. In this paper we extend the reach of the theory for the first time to the setting of general linear operators defined on normed spaces. The scope of this theory includes multilinear Fourier restriction-type inequalities. We also sharpen our previous theory of positive operators. Our results all share a common theme: estimates on a weighted geometric mean of linear operators can be disentangled into quantitative estimates on each operator separately. The concept of disentanglement recurs throughout the paper. The methods we used in the previous work - principally convex optimisation - relied strongly on positivity. In contrast, in this paper we use a vector-valued reformulation of disentanglement, geometric properties (Rademacher-type) of the underlying normed spaces, and probabilistic considerations related to p-stable random variables.

In dimensions $n \geq 4$, an ancient $κ$-solution is a nonflat, complete, ancient solution of the Ricci flow that is uniformly PIC and weakly PIC2; has bounded curvature; and is $κ$-noncollapsed. We show that the only noncompact ancient $κ$-solutions up to isometry are a family of shrinking cylinders, a quotient thereof, or the Bryant soliton.

Glacial Lake Outburst Flood (GLOF) Hazard Mitigation at Himalayan Region, Nepal

Publisher: name: University of East London
Year: 2021

description: Glacier retreat is a strong indicator of climate change and global warming. The anthropogenic changes in the Earth's atmosphere are mostly to blame for the climate extremes and their consequences in the last few decades. The Himalayan region is no exclusion to the trend. As glaciers begin to retreat, the glacial lake starts to fill or form behind the natural moraine or ice dam in the glaciers. The sudden release of the water, known as the Glacial Lake Outburst Flood (GLOF), can release a large amount of water and sediment. There have been various destructive GLOFs recorded in Nepal since the 1960s. It is vital to understand the GLOF dynamics, geomorphology and historical events to mitigate the GLOF hazards in the region. An advanced approach based on remote sensing data and empirical evidence is more suitable to tackle these issues. This research investigated 11 among 30 past events recorded in the HKH region (Nepal) to establish the causes and triggering factors that led to the catastrophic failure, which helped establish the vulnerability assessment of these glacial lakes. This eventually led to creating a GLOF vulnerability assessment framework that is unique and useful to the communities. This research concluded that 40% of the GLOF events was due to the moraine dam failure. In the retrospective approach, 5 out of 11 glacial lakes scored a very high total vulnerability score (TVR), which suffered catastrophic events in the past. The TVR of the currently existing 21 potential dangerous glacial lakes (PDGL) in Nepal was also conducted using the proposed assessment framework that concluded the 7 very high, 4 high, 5 medium, and the rest are low. Hence, this assessment tool's reliability is very high. This research also concluded that there should integrated approach to climate change adaptation and hazard mitigations in the region.

description: The chemical vapor deposition (CVD) diamond Brewster-angle window is a very promising broadband radio-frequency (RF) output window solution for frequency step-tunable high power gyrotrons foreseen in nuclear fusion devices like DEMO. Since gyrotrons operate in the megawatt-class power range, active cooling of the output window during operation is mandatory for long pulse operation. In this paper, different indirect cooling layouts were investigated and compared by finite element method (FEM) thermal and structural analyses. Scenarios with different power and frequency beam were taken into account in the analyses.
Investigating COBRA's role in regulating cellulose biosynthesis in Arabidopsis thaliana
Creators: name: Li, Donglei
Publisher: name: University of British Columbia
Year: 2022

description: Plant cell shape is defined by the cell wall. Cellulose microfibrils, which are the major component of the plant cell walls, serve as tension-bearing structures during cell expansion and are important for cells to maintain unidirectional growth and determine cell shape. Cellulose biosynthesis in plants is under tight regulation, it is carried out by cellulose synthases (CESA), arranged in complexes in the plasma membrane. COBRA(COB) was identified as an essential gene for maintaining cell elongation and root anisotropic growth in Arabidopsis (Arabidopsis thaliana). COB is highly expressed in shoot and root elongation zones and is co-expressed with primary cell wall CESAs. Although previous studies have determined COB’s critical role in cellulose synthesis, it is still not clear that the mechanism on how COB is involved in cellulose biosynthesis. Studies in the Wasteneys lab indicate that COB likely plays a role in the regulation of cellulose biosynthesis. With the successful generation of cYFP-conjugated COB (COB-cYFP; COB-mcYFP) and 6x histidine-tagged COB (HisCOB) translational reporter fusion constructs, we were able to detect COB puncta in the cytoplasm and discover that COB undergoes two cleavage events after its secretion to the cell wall, followed by the endocytosis of a polypeptide following cleavage in the cell wall (Chapter 1). In chapter 2, I explored the basis for the cob-1 cellulose deficiency and swollen root phenotype under high sucrose. I used site-directed mutagenesis to re-engineer the HisCOB construct with the cob-1 point mutation, and successfully transformed this new construct (His-cob-1) into the cob-4 background to generate stable transgenic lines. I demonstrated that the His-cob-1 line can be used to purify protein using a gravity column with nickel-conjugated agarose beads, and detected 65 kDa, 48 kDa, and 28 kDa polypeptides from cytosolic extracts. The His-cob-1 cob-4 line is an important resource for future investigations aimed at determining how COB cleavage modulates cellulose production. In chapter 3, I investigated the potential of several candidate enzymes to cleave COB in the extracellular region (Chapter 3). Ultimately, this thesis furthers our understanding of the mechanisms by which COBRA maintains cellulose biosynthesis and unidirectional cell growth during rapid expansion.
Inclination Mixing in the Classical Kuiper Belt

description: We investigate the long-term evolution of the inclinations of the known classical and resonant Kuiper belt objects (KBOs). This is partially motivated by the observed bimodal inclination distribution and by the putative physical differences between the low- and high-inclination populations. We find that some classical KBOs undergo large changes in inclination over gigayear timescales, which means that a current member of the low-inclination population may have been in the high-inclination population in the past, and vice versa. The dynamical mechanisms responsible for the time-variability of inclinations are predominantly distant encounters with Neptune and chaotic diffusion near the boundaries of mean motion resonances. We reassess the correlations between inclination and physical properties including inclination time-variability. We find that the size-inclination and color-inclination correlations are less statistically significant than previously reported (mostly due to the increased size of the data set since previous works with some contribution from inclination variability). The time-variability of inclinations does not change the previous finding that binary classical KBOs have lower inclinations than non-binary objects. Our study of resonant objects in the classical Kuiper belt region includes objects in the 3:2, 7:4, 2:1, and eight higher-order mean motion resonances. We find that these objects (some of which were previously classified as non-resonant) undergo larger changes in inclination compared to the non-resonant population, indicating that their current inclinations are not generally representative of their original inclinations. They are also less stable on gigayear timescales.

description: The article considers one of the methods of strategic risk evaluation as a mandatory component of the risk management system in accordance with the requirements of Basel III. The need for quantitative assessment of this type of risk, which is weakly formalized, is regulated by the National Bank of Ukraine [1] within the framework of approximation to the Basel III capital management standards and provisions of the EU regulatory documents on capital requirements (CRD IV [2]). Thus, the National Bank of Ukraine gradually implements the above requirements and monitors its implementation. The RAPBM model [2, 3] has been proposed for strategic risk assessment. Calculation of strategic risk with the help of this model allows estimating sensitivity indicators and margin safety of the bank to systemic crises. The paper explores the possibility of applying the RAPBM model to analyze the impact of the Covid-19 crisis, considering the changes related to the implementation of IFRS 9 in the banking sector of Ukraine from January 1, 2018.

description: It has been shown by us recently that Einstein was right in his controversy with Bohr or that the so called hidden-variable theory should be preferred to the Copenhagen quantum mechanics. In the following paper the corresponding arguments will be shortly repeated. The main attention will be then devoted to explaining main differences between these two quantum alternatives, differing in the access to the problem of chance, causality and locality of microscopic objects. The actual meaning of the mentioned hidden variables will be discussed, too, the essence of which remained practically unclear during all past discussions. It will be shown that the theory of hidden variables (or Schroedinger equation alone) is able to represent the properties of the whole known physical reality.

description: For an absolutely continuous (integer-valued) r.v. $X$ of the Pearson (Ord) family, we show that, under natural moment conditions, a Stein-type covariance identity of order $k$ holds (cf. [Goldstein and Reinert, J. Theoret. Probab. 18 (2005) 237--260]). This identity is closely related to the corresponding sequence of orthogonal polynomials, obtained by a Rodrigues-type formula, and provides convenient expressions for the Fourier coefficients of an arbitrary function. Application of the covariance identity yields some novel expressions for the corresponding lower variance bounds for a function of the r.v. $X$, expressions that seem to be known only in particular cases (for the Normal, see [Houdré and Kagan, J. Theoret. Probab. 8 (1995) 23--30]; see also [Houdré and Pérez-Abreu, Ann. Probab. 23 (1995) 400--419] for corresponding results related to the Wiener and Poisson processes). Some applications are also given.

description: Using the platform of a trapped-atom clock on a chip, we observe the time evolution of spin-squeezed hyperfine clock states in ultracold rubidium atoms on previously inaccessible timescales up to 1 s. The spin degree-of-freedom remains squeezed after 0.6 s, which is consistent with the limit imposed by particle loss and is compatible with typical Ramsey times in state-of-the-art microwave clocks. The results also reveal a surprising spin-exchange interaction effect that amplifies the cavity-based spin measurement via a correlation between spin and external degrees of freedom. These results open up perspectives for squeezing-enhanced atomic clocks in a metrologically relevant regime and highlight the importance of spin interactions in real-life applications of spin squeezing.

description: In this work we study the properties of a relativistic mixture of two non-reacting dilute species in thermal local equilibrium. Following the conventional ideas in kinetic theory, we use the concept of chaotic velocity. In particular, we address the nature of the density, or pressure gradient term that arises in the solution of the linearized Boltzmann equation in this context. Such effect, also present for the single component problem, has so far not been analyzed from the point of view of the Onsager resciprocity relations. In order to address this matter, we propose two alternatives for the Onsagerian matrix which comply with the corresponding reciprocity relations and also show that, as in the non-relativistic case, the chemical potential is not an adequate thermodynamic force. The implications of both representations are briefly analyzed.

description: An adaptive modified weak Galerkin method (AmWG) for an elliptic problem is studied in this paper, in addition to its convergence and optimality. The modified weak Galerkin bilinear form is simplified without the need of the skeletal variable, and the approximation space is chosen as the discontinuous polynomial space as in the discontinuous Galerkin method. Upon a reliable residual-based a posteriori error estimator, an adaptive algorithm is proposed together with its convergence and quasi-optimality proved for the lowest order case. The primary tool is to bridge the connection between the modified weak Galerkin method and the Crouzeix-Raviart nonconforming finite element. Unlike the traditional convergence analysis for methods with a discontinuous polynomial approximation space, the convergence of AmWG is penalty parameter free. Numerical results are presented to support the theoretical results.

description: This paper presents the results of the formation of vortex long-lived plasma formations (LLPF) using a plasma gun an ablation pulsed plasma accelerator. Discharge duration ~ 0.6 ms. LLPF evolution was recorded using a high-speed camera. The vortex lifetime reached 30 ms. The conditions for the formation of an LLPF have been determined. It has been found that an increase in the discharge power reduces the stability of vortices and leads to a decrease in the life of plasma formations.

description: For any self-similar measure $μ$ in $\mathbb{R}$, we show that the distribution of $μ$ is controlled by products of non-negative matrices governed by a finite or countable graph depending only on the IFS. This generalizes the net interval construction of Feng from the equicontractive finite type case. When the measure satisfies the weak separation condition, we prove that this directed graph has a unique attractor. This allows us to verify the multifractal formalism for restrictions of $μ$ to certain compact subsets of $\mathbb{R}$, determined by the directed graph. When the measure satisfies the generalized finite type condition with respect to an open interval, the directed graph is finite and we prove that if the multifractal formalism fails at some $q\in\mathbb{R}$, there must be a cycle with no vertices in the attractor. As a direct application, we verify the complete multifractal formalism for an uncountable family of IFSs with exact overlaps and without logarithmically commensurable contraction ratios.

description: The article describes the principles of operation of the “Methodology for using mathematical principles of automation of the creation of an independent thesaurus based on a hypertext system”. Nowadays, the thesaurus cannot be created completely automatically. However, there are many successful attempts to partially automate this process. To create a thesaurus, you need to have a concept of a thesaurus. For this purpose, a model of knowledge about the thesaurus is being developed. This article discusses how to apply the mathematical principles of automation of thesaurus creation.

description: Atomic nanowires formed by Au on Ge(001) are scrutinized for the band topology of the conduction electron system by k-resolved photoemission. Two metallic electron pockets are observed. Their Fermi surface sheets form straight lines without undulations perpendicular to the chains within experimental uncertainty. The electrons hence emerge as strictly confined to one dimension. Moreover, the system is stable against a Peierls distortion down to 10 K, lending itself for studies of the spectral function. Indications for unusually low spectral weight at the chemical potential are discussed.

description: We consider the one-dimensional nonlinear Schrödinger equation with an attractive delta potential and mass-supercritical nonlinearity. This equation admits a one-parameter family of solitary wave solutions in both the focusing and defocusing cases. We establish asymptotic stability for all solitary waves satisfying a suitable spectral condition, namely, that the linearized operator around the solitary wave has a two-dimensional generalized kernel and no other eigenvalues or resonances. In particular, we extend our previous result beyond the regime of small solitary waves and extend the results of Fukuizumi-Ohta-Ozawa and Kaminaga-Ohta from orbital to asymptotic stability for a suitable family of solitary waves.

description: Modern surveys of gravitational microlensing events have progressed to detecting thousands per year. Surveys are capable of probing Galactic structure, stellar evolution, lens populations, black hole physics, and the nature of dark matter. One of the key avenues for doing this is studying the microlensing Einstein radius crossing time distribution ($t_E$). However, systematics in individual light curves as well as over-simplistic modeling can lead to biased results. To address this, we developed a model to simultaneously handle the microlensing parallax due to Earth's motion, systematic instrumental effects, and unlensed stellar variability with a Gaussian Process model. We used light curves for nearly 10,000 OGLE-III and IV Milky Way bulge microlensing events and fit each with our model. We also developed a forward model approach to infer the timescale distribution by forward modeling from the data rather than using point estimates from individual events. We find that modeling the variability in the baseline removes a source of significant bias in individual events, and previous analyses over-estimated the number of long timescale ($t_E>100$ days) events due to their over simplistic models ignoring parallax effects and stellar variability. We use our fits to identify hundreds of events that are likely black holes.

Effects of warming temperatures on phytoplankton community composition and nutritional quality
Creators: name: Kim, Jihyun
Publisher: name: University of British Columbia
Year: 2022

description: Climate change is resulting in ongoing temperature warming and increased frequencies of heatwaves. In aquatic ecosystems, temperature not only affects the distribution and abundance of phytoplankton, but warming may also be reducing the quantities of key nutrients produced by these important primary producers. However, thus far most research in this field has examined the effects of warming temperatures on nutrient production in individual species of phytoplankton. To characterize how warming affects phytoplankton-based nutrients at the community scale, we subjected naturally occurring phytoplankton assemblages to three temperature treatments (ambient, warming, heat wave) in a seven-week laboratory experiment. We used community-wide fatty acid composition and stoichiometric indicators (C:N, C:P and N:P ratios) as our measures of phytoplankton nutritional quality. By the end of the experiment, there was no effect of temperature on phytoplankton community composition. Phytoplankton communities from the heatwave treatment had decreased concentrations of C, N and P, but neither the heatwave nor warming affected community-wide C:N, C:P and N:P ratios. Both warming and the heatwave reduced phytoplankton polyunsaturated fatty acid (PUFA) content, but as the heatwave subsided, PUFA quantities in this treatment approached those found in the ambient temperature treatment. We then fed warmed phytoplankton communities to naturally-collected zooplankton assemblages and found that the PUFA composition of the zooplankton communities closely reflected that of their food source. Our results suggest that 1) temperature warming has negative effects on phytoplankton community nutritional quality, 2) these responses are not caused by broad-scale shifts in phytoplankton taxonomy, and 3) phytoplankton PUFA levels appear to closely track water temperature. Furthermore, we provide evidence that zooplankton communities experience indirect effects of temperature warming through nutritional shifts in their phytoplankton resource. Overall, this study improves our understanding of the types of phytoplankton nutrients that are affected by warming, how quickly these nutrients can respond to temperature change, and the down-stream effects of phytoplankton-based nutrients on zooplankton consumers.

description: Tests with cosmic ray muons of a small liquid argon time projection chamber (LAr TPC) in a magnetic field of 0.55 T are described. No effect of the magnetic field on the imaging properties were observed. In view of a future large, magnetized LAr TPC, we investigated the possibility to operate a high temperature superconducting (HTS) solenoid directly in the LAr of the detector. The critical current $I_c$ of HTS cables in an external magnetic field was measured at liquid nitrogen and liquid argon temperatures and a small prototype HTS solenoid was built and tested.
