description: Phytochemical investigation of the whole plants of Lycopodiella cernua resulted in the isolation and identification of three new compounds (1–3), namely lycocernuaside E (1), lycernuic ketone F (2), and lycernuic B (3) and 12 known ones (4–15). Their chemical structures were established based on 1 D/2D NMR spectroscopic and HR-ESI-MS data analyses. Compounds 5, 12, and 13 displayed NO inhibitory effects in LPS-stimulated BV2 cells, with IC50 values of 21.2 ± 1.1, 28.5 ± 1.4, and 21.9 ± 1.1 µM, respectively. In addition, cytotoxic activity of the isolated compounds against MCF7 (breast carcinoma), HepG2 (hepatocarcinoma), and SK-Mel2 (melanoma) cancer cell lines were also reported.

description: Osteoarthritis (OA) is a major cause of chronic pain and joint damage, involving low-grade synovitis that contributes to disease progression. Fibroblast-like synoviocytes (FLSs) are central to this process, producing inflammatory cytokines regulated by calcium (Ca2+) signaling. Targeting Ca2+ signaling through store-operated calcium entry (SOCE) could help reduce inflammation in OA.We  tested two novel SOCE-negative modulators (CIC-39 and BIP-26) and two drugs (methotrexate and celecoxib) on inflamed OA-FLSs. CIC-39 and BIP-26 reduced Ca2+ influx without affecting cell morphology or viability. Methotrexate and the SOCE modulators showed trends toward reducing cytokine expression, though results were not statistically significant. Celecoxib induced cell death in a dose-dependent manner and caused cell cycle arrest. Overall, SOCE modulators show potential as a new treatment strategy for OA.

description: In 2014 a previously unknown rural medieval pottery kiln and associated features comprising elements of a workshop and a possible road surface were recorded during archaeological mitigation works associated with the development of Lucker Hall, Lucker, Northumberland. The excavated kiln was radiocarbon-dated to the late 13th or 14th century and ceramics recovered from associated deposits suggest that two previously unknown fabrics (provisionally named as Lucker Hall ware and Lucker Hall-type ware) were produced at the site. To date, very few medieval potteries have been excavated in North East England and Lucker Hall ware has yet to be identified as a specific type on other sites.

We calculate the effective action in the presence of constant external magnetic field $B$ (normal to the graphene sheet). We also calculate the first two corrections to this effective action caused by the in-plane electric field $E$ at $E/B \ll 1$ and discuss the magnetoelectric effect. In addition, we calculate the imaginary part of the effective action in the presence of constant electric field $E$ and the lowest order correction to it due to the magnetic field ($B/E \ll 1$).

Using product-specific fuelwood yields to assess economic viability : a case study of farm-based Gliricidia sepium and Caesalpinia velutina plantations in Nicaragua
Creators: name: Baker, Kahlil
Publisher: name: University of British Columbia
Year: 2012

description: Non-industrial fuelwood plantations are commonly seen as a means of improving rural livelihoods while helping to meet energy demand. However, for smallholders to invest in the establishment of fuelwood plantations, economic viability is required. Two of the greatest sources of uncertainty in evaluating the economic viability of fuelwood plantations are the effects that market-specific requirements can have on the stumpage price a plantation owner can hope to receive and the lack of appropriate growth and yield information. The primary objective of this thesis was to determine if Caesalpinia velutina and Gliricidia sepium fuelwood plantations in Nicaragua could be economically viable in the smallholder context if sold within the market place. To improve the accuracy of the economic viability assessment, a novel approach was used that forecasted fuelwood yields by market-specific product segments, thereby accounting for the effects of market requirements on differential revenues and costs. Data on market demand, product segment dimensions and prices were collected by measuring fuelwood logs and by interviewing fuelwood consuming business owners. To forecast fuelwood log volume by product segments, species-specific yield models based on three separate sub-models were developed: 1) mean diameter at breast height (DBH) predicted over time; 2) mean height as a function of mean DBH; and 3) taper as a function of mean DBH and mean height. Mortality was assumed to be zero, following establishment mortality. To assess economic viability, information on costs, discount rates, market requirements and fuelwood yields by product segment were combined using the net present value (NPV) and the internal rate of return (IRR). It was concluded that fuelwood plantation yields according to product-specific requirements were essential for the economic viability analysis. In the context of this study, farm-based Caesalpinia velutina and Gliricidia sepium fuelwood plantations could be economically viable over longer rotations. However, barriers to entry such as access to capital and the need for reaching economies of scale made it unlikely that fuelwood plantations could be economically viable for smallholders without institutional support.

Their chemical structures were determined to be (1S,6R,7S)-muurola-4,10(14)-diene-15-ol (1), quercetin 3-O-β-D-apiofuranosyl-(1→2)-α-L-arabinofuranoside (2), quercetin 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinofuranoside (3), quercetin 3-O-α-L-arabinofuranoside (4), kaempferol 3-O-β-D-apiofuranosyl-(1→2)-α-L-arabinofuranoside (5), kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinofuranoside (6), and kaempferol 3-O-α-L-arabinofuranoside (7) by analyses of HR-ESI-MS and NMR spectral data. Compounds 4 and 7 containing monosaccharide, arabinofuranoside, potentially inhibited NO productions in LPS activated RAW264.7 cells (IC50 13.4 ± 0.5 and 12.6 ± 0.4 µM) in compared to disaccharide derivatives (IC50 ranging from 58.9 ± 3.3 to 65.6 ± 3.8 µM).

description: The ground-state energy of integrably-twisted theories is analyzed in finite volume. We derive the leading and next-to-leading order (NLO) Lüscher-type corrections for large volumes of the vacuum energy for integrable theories with twisted boundary conditions and twisted S-matrix. We then derive the twisted thermodynamic Bethe ansatz (TBA) equations to describe exactly the ground state, from which we obtain an untwisted Y-system. The two approaches are compared by expanding the TBA equations to NLO, and exact agreement is found. We give explicit results for the O(4) model and for the three-parameter family of $γ$-deformed (non-supersymmetric) planar AdS/CFT model, where the ground-state energy can be nontrivial and can acquire finite-size corrections. The NLO corrections, which correspond to double-wrapping diagrams, are explicitly evaluated for the latter model at six loops.

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 40, 55-70
description: This article sets out to map and explain the distribution of stoneware in the Low Countries during the period 1200-1600, using a selection of over 500 assemblages representing 30,000+ vessels (now available online: see Appendix 1). This exceptionally big dataset generates solid evidence for the distribution of stoneware outwards from an epicentre: the closer a town was situated to a stoneware production centre in the Meuse-Rhine area, the more frequent the appearance of stoneware. It also shows clearly how the ceramic record reflects the effect of contemporary trade routes: Langerwehe products were distributed along the Meuse and are most common in towns close to this river, while stonewares from Siegburg/Bruhl are dominant in towns connected with the Rhenish network. Documentary evidence is used to demonstrate how the inland occurrence of Rhenish stoneware is also governed by the Rhenish wine trade network extending from Cologne to Nijmegen and beyond, and how changing patterns in consumer demand affected this trade. Finally, some suggestions are made for future research.

Alzheimer's disease

description: BACKGROUND: We previously reported that the Mediterranean diet (MeDi) is related to lower risk for Alzheimer disease (AD). Whether MeDi is associated with subsequent AD course and outcomes has not been investigated. OBJECTIVES: To examine the association between MeDi and mortality in patients with AD. METHODS: A total of 192 community-based individuals in New York who were diagnosed with AD were prospectively followed every 1.5 years. Adherence to the MeDi (0- to 9-point scale with higher scores indicating higher adherence) was the main predictor of mortality in Cox models that were adjusted for period of recruitment, age, gender, ethnicity, education, APOE genotype, caloric intake, smoking, and body mass index. RESULTS: Eighty-five patients with AD (44%) died during the course of 4.4 (+/-3.6, 0.2 to 13.6) years of follow-up. In unadjusted models, higher adherence to MeDi was associated with lower mortality risk (for each additional MeDi point hazard ratio 0.79; 95% CI 0.69 to 0.91; p = 0.001). This result remained significant after controlling for all covariates (0.76; 0.65 to 0.89; p = 0.001). In adjusted models, as compared with AD patients at the lowest MeDi adherence tertile, those at the middle tertile had lower mortality risk (0.65; 0.38 to 1.09; 1.33 years' longer survival), whereas subjects at the highest tertile had an even lower risk (0.27; 0.10 to 0.69; 3.91 years' longer survival; p for trend = 0.003). CONCLUSION: Adherence to the Mediterranean diet (MeDi) may affect not only risk for Alzheimer disease (AD) but also subsequent disease course: Higher adherence to the MeDi is associated with lower mortality in AD. The gradual reduction in mortality risk for higher MeDi adherence tertiles suggests a possible dose-response effect.
Positive recurrence of piecewise Ornstein-Uhlenbeck processes and common quadratic Lyapunov functions

description: We study the positive recurrence of piecewise Ornstein-Uhlenbeck (OU) diffusion processes, which arise from many-server queueing systems with phase-type service requirements. These diffusion processes exhibit different behavior in two regions of the state space, corresponding to "overload" (service demand exceeds capacity) and "underload" (service capacity exceeds demand). The two regimes cause standard techniques for proving positive recurrence to fail. Using and extending the framework of common quadratic Lyapunov functions from the theory of control, we construct Lyapunov functions for the diffusion approximations corresponding to systems with and without abandonment. With these Lyapunov functions, we prove that piecewise OU processes have a unique stationary distribution.

A few theoretical aspects concerning neutrino masses, leptonic mixing, and CP violation will be covered, with special emphasis on seesaw models. A discussion is provided on observable effects which are manifest in the presence of CP violation, particularly, in neutrino oscillations and neutrinoless double beta decay processes, and their possible implications in collider experiments such as the LHC. The role that leptonic CP violation may have played in the generation of the baryon asymmetry of the Universe through the mechanism of leptogenesis is also discussed.

description: Some of local sources of the slow solar wind can be associated with spectroscopically detected plasma outflows at edges of active regions accompanied with specific signatures in the inner corona. The EUV telescopes (e.g. SPIRIT/CORONAS-F, TESIS/CORONAS-Photon and SWAP/PROBA2) sometimes observed extended ray-like structures seen at the limb above active regions in 1MK iron emission lines and described as "coronal rays". To verify the relationship between coronal rays and plasma outflows, we analyze an isolated active region (AR) adjacent to small coronal hole (CH) observed by different EUV instruments in the end of July - beginning of August 2009. On August 1 EIS revealed in the AR two compact outflows with the Doppler velocities V =10-30 km/s accompanied with fan loops diverging from their regions. At the limb the ARCH interface region produced coronal rays observed by EUVI/STEREO-A on July 31 as well as by TESIS on August 7. The rays were co-aligned with open magnetic field lines expanded to the streamer stalks. Using the DEM analysis, it was found that the fan loops diverged from the outflow regions had the dominant temperature of ~1 MK, which is similar to that of the outgoing plasma streams. Parameters of the solar wind measured by STEREO-B, ACE, WIND, STEREO-A were conformed with identification of the ARCH as a source region at the Wang-Sheeley-Arge map of derived coronal holes for CR 2086. The results of the study support the suggestion that coronal rays can represent signatures of outflows from ARs propagating in the inner corona along open field lines into the heliosphere.

description: We study a two species fermion mixture with different populations on a square lattice modeled by a Hubbard Hamiltonian with on-site inter-species repulsive interaction. Such a model can be realized in a cold atom system with fermionic atoms in two different hyperfine states loaded on an optical lattice and with tunable inter-species interaction strength via external fields. For a two-dimensional square lattice, when at least one of the fermion species is close to half-filling, the system is highly affected by lattice effects. With the majority species near half-filling and varying densities for the minority species, we find that several correlated phases emerge as the ground state, including a spin density wave state, a charge density wave state with stripe structure, and various p-wave BCS pairing states for both species. We study this system using a functional renormalization group method, determine its phase diagram at weak coupling, discuss the origin and characteristics of each phase, and provide estimates for the critical temperatures.

description: We investigate the possibility of detecting Majorana neutrinos at the $e^+e^-$ Next Linear Collider (NLC). We study the $l_j^{\mp} l_k^{\mp} + jets$ ($l_j\equiv e ,μ,τ$) final states which are, due to leptonic number violation, a clear signature for intermediate Majorana neutrino contributions. Such signals (final leptons of the same-sign) are not possible if the heavy neutrinos have Dirac nature. The interactions between Majorana neutrinos and the Standard Model (SM) particles are obtained from an effective Lagrangian approach. As for the background, we considered the SM reaction $e^+ e^- \rightarrow W^+W^+W^-W^-$, with two $W^\prime$s decaying into jets and two $W^\prime$s decaying into $l^{\pm}+ν(\bar ν)$, producing extra light neutrinos which avoid the detection. We present our results for the total cross-section as a function of the neutrino mass and the center of mass energies. We also show the discovery region as a function of the Majorana neutrino mass and the effective coupling.

Multilevel Quasi-Interpolation With a Gaussian Kernel using Chebyshev Points - Numerical and theoretical studies using the radial basis function approach
Creators: name: Alsharif, Faisal
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Radial basis functions (RBFs) have been recently begun to see widespread use in fitting scattered data in Rd and, for this purpose, have been found to be highly effective. However, there are limitations to RBFs in the interpolation of two dimensions, three dimensions, or higher, with large datasets in Rd. In this thesis, we propose a novel multilevel quasi-interpolation method with Gaussian kernels and Chebyshev points associated with a sparse grid (Chapter 2 and Chapter 3). The primary aim is to offer a method that uses a sparser grid with fast convergence, as shown in Section 2.3 and Section 3.3. In Chapter 1, the thesis lays down the mathematical groundwork, introducing key concepts like RBFs, quasiinterpolation, and anisotropic tensor product basis functions. It also discusses the challenges of working with multidimensional data in Section 1.8. Chapter 2 specifically delves into quasi-interpolation on Chebyshev points, introducing boundary corrections to improve the method’s performance (Section 2.2). The use of Gaussian kernels in this context, analysed to provide both smoothness and better locality, contribute to excellent approximative properties. This is supported by numerical experiments (Section 2.3). The core contribution lies in Chapter 3, where a multilevel sparse-grid quasiinterpolation technique is developed. This approach, inspired by the work in [1, 2], is effective for large datasets in Rd with d = 2, 3 and higher. The algorithm described in Section 3.2 employs direction-wise multilevel decomposition and distinct scaling in each direction, resulting in quicker convergence. Numerical validation confirms that quasi-sparse interpolation with Chebyshev points has advantages in terms of complexity, runtime, and convergence when compared to classical methods (Sections 3.3). The thesis concludes with Chapter 4 by summarising the contributions made and proposing possible future work.

description: We investigate over a 12-year period the association between regional cerebral blood flow (CBF) and cardiovascular risk factors in a prospective cohort of healthy older adults (81.96 +/- 3.82 year-old) from the Cognitive REServe and Clinical ENDOphenotype (CRESCENDO) study. Cardiovascular risk factors were measured over 12 years, and gray matter CBF was measured at the end of the study from high-resolution magnetic resonance imaging using arterial spin labeling. The association between cardiovascular risk factors, their long-term change, and CBF was assessed using multivariate linear regression models. Women were observed to have higher CBF than men (p < 0.05). Increased mean arterial pressure (MAP) over the 12-year period was correlated with a low cerebral blood flow (p < 0.05, R(2) = 0.21), whereas no association was detected between CBF and MAP at the time of imaging. High levels of glycemia tended to be associated with low cerebral blood flow values (p < 0.05). Age, alcohol consumption, smoking status, body mass index, history of cardiovascular disease, and hypertension were not associated with CBF. Our main result suggests that change in MAP is the most significant predictor of future CBF in older adults.

description: We provide a detailed study of the general structure of two-dimensional topological stabilizer quantum error correcting codes, including subsystem codes. Under the sole assumption of translational invariance, we show that all such codes can be understood in terms of the homology of string operators that carry a certain topological charge. In the case of subspace codes, we prove that two codes are equivalent under a suitable set of local transformations if and only they have equivalent topological charges. Our approach emphasizes local properties of the codes over global ones.

description: Cognitive reserve (CR) is a concept meant to account for the frequent discrepancy between an individual's measured level of brain pathology and her expected cognitive performance. It is particularly important within the context of aging and dementia, but has wider applicability to all forms of brain damage. As such, it has intimate links to related compensatory and neuroprotective concepts, as well as to the related notion of brain reserve. In this article, we introduce the concept of cognitive reserve and explicate its potential cognitive and neural implementation. We conclude that cognitive reserve is compatible and complementary with many related concepts, but that each much draw sharper conceptual boundaries in order to truly explain preserved cognitive function in the face of aging or brain damage.

description: The superconducting system La2-xBaxCuO4 is known to show a minimum in the transition temperature, Tc, at x = 1/8 where maximal stripe order is pinned by the anisotropy within the CuO2 planes that occurs in the low-temperature-tetragonal (LTT) crystal structure. For x = 0.095, where Tc reaches its maximum value of 32 K, there is a roughly coincident structural transition to a phase that is very close to LTT. Here we present a neutron scattering study of the structural transition, and demonstrate how features of it correlate with anomalies in the magnetic susceptibility, electrical resistivity, thermal conductivity, and thermoelectric power. We also present measurements on a crystal with 1% Zn substituted for Cu, which reduces Tc to 17 K, enhances the spin stripe order, but has much less effect on the structural transition. We make the case that the structural transition correlates with a reduction of the Josephson coupling between the CuO2 layers, which interrupts the growth of the superconducting order. We also discuss evidence for two-dimensional superconducting fluctuations in the normal state, analyze the effective magnetic moment per Zn impurity, and consider the significance of the anomalous thermopower often reported in the stripe-ordered phase.

description: We present an effective atomic interaction potential for crystalline alpha-Al2O3 generated by the program potfit. The Wolf direct, pairwise summation method with spherical truncation is used for electrostatic interactions. The polarizability of oxygen atoms is included by use of the Tangney-Scandolo interatomic force field approach. The potential is optimized to reproduce the forces, energies and stresses in relaxed and strained configurations as well as {0001}, {10-10} and {11-20} surfaces of Al2O3. Details of the force field generation are given, and its validation is demonstrated. We apply the developed potential to investigate crack propagation in alpha-Al2O3 single crystals.

description: A model relating radiative seesaw and minimal dark matter mass scales without beyond the standard model (SM) gauge symmetry (R$ν$MDM) is constructed. In addition to the SM particles, the R$ν$MDM contains, a Majorana fermion multiplet $N_R$ and scalar multiplet $χ$ that transform respectively as $(1,5,0)$ and $(1,6,-1/2)$ under the SM gauge group $SU(3)_C\times SU(2)_L\times U(1)_Y$. The neutral component $N_R^0$ plays the role of dark matter with a mass in the range of 9 to 10 TeV. This scale also sets the lower limit for the scale for the heavy degrees of freedom in $N_R$ and $χ$ which generate light neutrino masses through the radiative seesaw mechanism. The model predicts an $N_R^0$-nucleus scattering cross section that would be accessible with future dark matter direct detection searches as well as observable effects in present and searches for charged lepton flavor violating processes, such as $l_i\to l_j γ$ and $μ- e$ conversion.

description: The generation of spikes by neurons is energetically a costly process and the evaluation of the metabolic energy required to maintain the signalling activity of neurons a challenge of practical interest. Neuron models are frequently used to represent the dynamics of real neurons but hardly ever to evaluate the electrochemical energy required to maintain that dynamics. This paper discusses the interpretation of a Hodgkin-Huxley circuit as an energy model for real biological neurons and uses it to evaluate the consumption of metabolic energy in the transmission of information between neurons coupled by electrical synapses, i.e. gap junctions. We show that for a single postsynaptic neuron maximum energy efficiency, measured in bits of mutual information per ATP molecule consumed, requires maximum energy consumption. On the contrary, for groups of parallel postsynaptic neurons we determine values of the synaptic conductance at which the energy efficiency of the transmission presents clear maxima at relatively very low values of metabolic energy consumption. Contrary to what it could be expected best performance occurs at low energy cost.

Open source city : a proposal for a city tool shop
Creators: name: Kozak, Laura
Publisher: name: University of British Columbia
Year: 2012

description: Despite a history of participatory planning, urban activism and DIY building culture in Vancouver, Canada, current approaches to city-making have limited the agency of individuals in engaging with the built environment. This work investigates the changing conditions that have made it difficult for ordinary citizens to participate in small-scale construction, building repair, and navigation of permitting and rezoning processes. It addresses these barriers with a proposal for a facility that will support the work of DIY enthusiasts; individuals engaged in renovations or repairs; and neighbourhood activists and advocates. The proposal is presented in the form of a business plan for a City Tool Shop, a socially-enterprising non profit business located in Vancouver, Canada.

description: In two-dimensional forced Navier-Stokes turbulence, energy cascades to the largest scales in the system to form a pair of coherent vortices known as the Bose condensate. We show, both numerically and analytically, that the energy condensation saturates and the system reaches a statistically stationary state. The time scale of saturation is inversely proportional to the viscosity and the saturation energy level is determined by both the viscosity and the force. We further show that, without sufficient resolution to resolve the small-scale enstrophy spectrum, numerical simulations can give a spurious result for the saturation energy level. We also find that the movement of the condensate is similar to the motion of an inertial particle with an effective drag force. Furthermore, we show that the profile of the saturated coherent vortices can be described by a Gaussian core with exponential wings.

Alzheimer's disease--Patients--Care
Medical care, Cost of

description: OBJECTIVES: To estimate long-term trajectories of direct cost of caring for patients with Alzheimer disease (AD) and examine the effects of patients' characteristics on cost longitudinally. METHODS: The sample is drawn from the Predictors Study, a large, multicenter cohort of patients with probable AD, prospectively followed up annually for up to 7 years in three university-based AD centers in the United States. Random effects models estimated the effects of patients' clinical and sociodemographic characteristics on direct cost of care. Direct cost included cost associated with medical and nonmedical care. Clinical characteristics included cognitive status (measured by Mini-Mental State Examination), functional capacity (measured by Blessed Dementia Rating Scale [BDRS]), psychotic symptoms, behavioral problems, depressive symptoms, extrapyramidal signs, and comorbidities. The model also controlled for patients' sex, age, and living arrangements. RESULTS: Total direct cost increased from approximately 9,239 dollars per patient per year at baseline, when all patients were at the early stages of the disease, to 19,925 dollars by year 4. After controlling for other variables, a one-point increase in the BDRS score increased total direct cost by 7.7%. One more comorbid condition increased total direct cost by 14.3%. Total direct cost was 20.8% lower for patients living at home compared with those living in an institutional setting. CONCLUSIONS: Total direct cost of caring for patients with Alzheimer disease increased substantially over time. Much of the cost increases were explained by patients' clinical and demographic variables. Comorbidities and functional capacity were associated with higher direct cost over time.

description: Previous studies of oral physostigmine in the treatment of Alzheimer's disease have: (1) assumed physostigmine is effective only in mildly affected patients; (2) relied on an initial “dose-finding” phase to determine the most effective dose and excluded nonresponders; and (3) primarily assessed memory. We examined the response of 22 patients to six different daily dosages of oral physostigmine, using selective reminding tests that were administered twice daily. Nine patients had a “best” dose/day (mode = 13 mg/day), which was used in a subsequent double-blind crossover study. The otehr 13 were given the highest tolerated dose. The selective reminding test and a full neuropsychological battery were given during the drug and placebo periods. As a group, the 22 patients improved significantly on the Wechsler Adult Intelligence Scale—Revised Digit Symbol subtest and a shape cancelation task (p < 0.05). Nine patients showed improved performance on the selective reminding test during physostigmine treatment, and 9 showed no response; 4 patients performed better during placebo treatment. Dose finding did not help in predicting response in the crossover study; only 2 of the 9 who showed improvement had a best dose. Dementia severity did not predict corssover response. This suggests that: (1) physostigmine as administered had no pronounced effect on memory in Alzheimer's disease; (2) oral physostigmine produces no greater benefits on memory in mildly than in moderately demented patients; (3) response in a dose-finding phase does not predict response in double-blind crossover; and (4) Digit Symbol and cancelation tasks may be more sensitive than memory tests to the effects of oral physostigmine.
