Ameliorating Ageing and Age-Related Diseases by Targeting Senescent Cells

description: Senescence is a state of permanent cell cycle arrest with specific phenotypic features. Senescent cells have a positive role during wound healing, embryogenesis and as an anti-cancer mechanism, but they also accumulate in tissues with age, contributing towards the pathology of ageing and age-related diseases. This happens primarily through the release of the senescence-associated secretory phenotype (SASP).
Removal of senescent cells is known to improve health and life span in animal models; therefore, it is important to devise strategies to prevent senescent cell accumulation that could be used in humans. Here, we show that Ibrutinib, a BTK inhibitor, can ameliorate liver ageing in Zmpste24-deficient mouse model of progeria by reducing the accumulation of senescent cells. We used mass spectrometry to define the ageing proteomes and metabolomes of mice livers in response to ibrutinib. Three proteins, Fggy, Mtbp and Myo19, were reduced in aged livers compared to the livers of ibrutinib-treated and young mice, while Ceacam5 was increased. A proteolysis targeting chimera (PROTAC) for BTK was also investigated but showed no ability to prevent senescence.
Additionally, we tested drugs that could selectively eliminate senescent cells (senolytics). For instance, previous data suggested 9-OH-Ellipticine and A1331852 had a synergistic senolytic effect. The drugs were trialled as monotherapies and in combination in mice, but there was no evidence they had an in vivo effect.

description: We obtain full moduli parameters for generic non-planar BPS networks of domain walls in an extended Abelian-Higgs model with $N$ complex scalar fields, and exhaust all exact solutions in the corresponding $\mathbb{C}P^{N -1}$ model. We develop a convenient description by grid diagrams which are polytopes determined by mass parameters of the model. To illustrate the validity of our method, we work out non-planar domain wall networks for lower $N$ in $3+1$ dimensions. In general, the networks can have compact vacuum bubbles, which are finite vacuum regions surrounded by domain walls, when the polytopes of the grid diagrams have inner vertices, and the size of bubbles can be controlled by moduli parameters. We also construct domain wall networks with bubbles in the shapes of the Platonic, Archimedean, Catalan, and Kepler-Poinsot solids.

description: Recently, it was found that after imposing a helix boundary condition on a scalar field, the Casimir force coming from the quantum effect is linearly proportional to $r$, which is the ratio of the pitch to the circumference of the helix. This linear behavior of the Casimir force is just like that of the force obeying the Hooke's law on a spring. In this paper, inspiring by some complex structures that lives in the cells of human body like DNA, protein, collagen etc., we generalize the helix boundary condition to a more general one, in which the helix consists of a tiny helix structure, and makes up a hierarchy of helix. After imposing this kind of boundary condition on a massless and a massive scalar, we calculate the Casimir energy and force by using the so-called zeta function regularization method. We find that the Hooke's law with the generalized helix boundary condition is not exactly the same as usual one. In this case, the force is proportional to the cube of $r$ instead. So we regard it as a generalized Hooke's law, which is complied by a \emph{generalized quantum spring}.

description: Possible indirect detection of neutralino, through its gamma-ray annihilation product, by the forthcoming GLAST satellite from our galactic halo, M31, M87 and the dwarf galaxies Draco and Sagittarius is studied. Gamma-ray fluxes are evaluated for the two representative energy thresholds, 0.1 GeV and 1.0 GeV, at which the spatial resolution of GLAST varies considerably. Apart from dwarfs which are described either by a modified Plummer profile or by a tidally-truncated King profiles, fluxes are compared for halos with central cusps and cores. It is demonstrated that substructures, irrespective of their profiles, enhance the gamma-ray emission only marginally. The expected gamma-ray intensity above 1 GeV at high galactic latitudes is consistent with the residual emission derived from EGRET data if the density profile has a central core and the neutralino mass is less than 50 GeV, whereas for a central cusp only a substantial enhancement would explain the observations. From M31, the flux can be detected above 0.1 GeV and 1.0 GeV by GLAST only if the neutralino mass is below 300 GeV and if the density profile has a central cusp, case in which a significant boost in the gamma-ray emission is produced by the central black hole. For Sagittarius, the flux above 0.1 GeV is detectable by GLAST provided the neutralino mass is below 50 GeV. From M87 and Draco the fluxes are always below the sensitivity limit of GLAST.

description: Australia has made outstanding contributions to the use of quantitative economic models in public policy discussions. That leading role is now threatened by the increasing use of econometric modellers in an advocacy, lawyer-like role, rather than as impartial sources of the best available technical advice. This development became inevitable once it became fashionable in Canberra during the mid 1980s to deny the existence of public goods and to force the funding of economic intelligence garnering increasingly into the private sector. This paper argues that we are all the losers.

description: The ability to control and measure the temperature of propagating microwave modes down to very low temperatures is indispensable for quantum information processing, and may open opportunities for studies of heat transport at the nanoscale, also in the quantum regime. Here we propose and experimentally demonstrate primary thermometry of propagating microwaves using a transmon-type superconducting circuit. Our device operates continuously, with a sensitivity down to $4\times 10^{-4}$ photons/$\sqrt{\mbox{Hz}}$ and a bandwidth of 40 MHz. We measure the thermal occupation of the modes of a highly attenuated coaxial cable in a range of 0.001 to 0.4 thermal photons, corresponding to a temperature range from 35 mK to 210 mK at a frequency around 5 GHz. To increase the radiation temperature in a controlled fashion, we either inject calibrated, wideband digital noise, or heat the device and its environment. This thermometry scheme can find applications in benchmarking and characterization of cryogenic microwave setups, temperature measurements in hybrid quantum systems, and quantum thermodynamics.

The package can be used, for example, for automatic generation of difference schemes for linear partial differential equations and for reduction of multiloop Feynman integrals. These two possible applications are illustrated by simple examples of the Laplace equation and a one-loop scalar integral of propagator type

description: Recently, ``CDM crisis'' is under discussion. The main point of this crisis is that number of substructures presented by cosmological N-body simulations based on CDM scenario for structure formation is much larger than observed substructures. Therefore, it is crucial for this crisis to discriminate whether expected number of CDM substructures really exist but non-luminous or do not exist. In this paper, we present a new idea to detect such invisible substructures by utilizing a gravitational lensing. Here, we consider quasars that are gravitationally lensed by a foreground galaxy. A substructure around the lensing galaxy may superposed on one of the lensed images of such quasars. In this situation, additional image splitting should occur in the image behind the substructure, and further multiple images are created. This is ``quasar mesolensing''. We estimate separation and time delay between further multiple images due to quasar mesolensing. The expected value is $1 \sim 30$ milli-arcsecond for the separation and future fine resolution imaging enable us to find invisible substructures, and is $1 \sim 10^3$ second for the time delay and high-speed monitoring of such quasar will be able to find ``echo''-like variation due to quasar mesolensing in intrinsic variability of the quasar. Furthermore, we evaluate that the optical depth for the quasar mesolensing is $\sim 0.1$. Consequently, if we monitor a few multiple quasars, we can find ``echo''-like variation in one of the images after intrinsic flux variations of quasars.

description: In an effort to elevate to higher grounds our understanding on the impact of the formation and evolution of bars in the formation and evolution of galaxies, we have developed a diagnostic tool to distinguish between recently formed and evolved bars. Our method was applied in the study of a sample of 14 galaxies and revealed that, apparently, AGN activity tends to appear in galaxies which have young bars rather than evolved bars. This suggests that the time scale for the fueling of AGN by bars is short, and may help to explain, for instance, why there is not a clear correlation between the presence of bars and AGN in galaxies.

description: This paper examines the current national accounts measure of real output for three major service industries in Australia. It finds that real output measures for government administration services; defence services; and property and business services are unsatisfactory. Alternative estimates are presented for government administration services and defence services for the period 1986/87-1993/94. The estimates for government administration services compare well with the current national accounts measure, whereas for defence services they indicate that real output has grown less quickly than previously thought. No estimates for property and business services are presented due to lack of data.

description: Despite the allegations of audit failure and the enormous publicity surrounding Arthur Andersen’s indictment, there is no systematic empirical evidence on characteristics of accounting information of clients of Arthur Andersen vis-à-vis other Big Six auditors. I examine whether earnings of Andersen’s Houston-based clients are timely in reporting bad news about future cash flows. I find that relative to a control group consisting of Houston-based clients audited by other Big Six auditors, earnings of Andersen clients are less timely in reporting bad news. Further, it appears that operating accruals of clients of Andersen are less effective in accelerating the timely recognition of bad news than operating accruals of non-Andersen clients. The findings suggest that the clients of Andersen’s Houston office engaged in aggressive accounting practices, including delayed recognition of publicly available bad news.
Cooperative NOMA for Downlink Asymmetric Interference Cancellation

description: This letter advances the non-orthogonal multiple access (NOMA) technique for cellular downlink co-channel interference mitigation, via exploiting the (limited) cooperation among base stations (BSs). Specifically, we consider a simplified but practically relevant scenario of two co-channel cells with asymmetric interference, i.e., only the user in one cell receives the strong interference from the BS in the other cell. To mitigate such interference, we propose a new cooperative NOMA scheme, where the interfered user's serving BS sends a superposed signal comprising both the desired message and the co-channel user's message (shared by the interfering BS). The co-channel user's signal is aimed to add constructively with the interfering BS's signal at the interfered user's receiver so that the combined interference with enhanced power can be effectively decoded and cancelled. This thus leads to a new problem on how to optimally allocate the transmit power for the two superposed messages. We provide the closed-form solution to this problem and investigate the conditions under which the performance of the proposed scheme is superior over the existing schemes.

description: Mathematical models have recently been used to cast doubt on the biotic origin of stromatolites. Here by contrast we propose a biotic model for stromatolite morphogenesis which considers the relationship between upward growth of a phototropic or phototactic biofilm ($v$) and mineral accretion normal to the surface ($λ$). These processes are sufficient to account for the growth and form of many ancient stromatolities. Domical stromatolites form when $v$ is less than or comparable to $λ$. Coniform structures with thickened apical zones, typical of Conophyton, form when $v >> λ$. More angular coniform structures, similar to the stromatolites claimed as the oldest macroscopic evidence of life, form when $v >>> λ$.

description: The University of British Columbia Food System Project (UBCFSP) is a “collaborative, community-based action research project” to assess, recommend, and implement measures towards a more sustainable food system at UBC (Rojas and Richer, 3). Scenario 1’s primary objective is to extend local purchasing at UBC. In this report, Group 28 considers the feasibility of holding a full-fledged farmers’ market hosted by Your Local Farmer’s Market Society (YLFMS) at the Centre For Sustainable Food Systems at UBC Farm. The following factors were explored: transportation in the form of a public bus stop at the UBC Farm, parking spaces, UBC Farm space allocations, marketing, educational programs to be run concurrently by UBC Farm, preliminary terms upon which both the UBC Farm and YLFMS would collaborate. Recommendations are then made to future UBCFSP students as well as the UBC Farm and UBC administration to further our goals next year. The appendix includes preliminary proposals to both the UBC Farm and YLFMS, describing the details for a beneficial collaboration that will meet the objectives of both organizations hosting a farmer’s market in the summer of 2007.

description: Game farming can be complementary, supplementary, competitive or antagonistic to livestock production. Little is yet known about financial returns to game farming. Ten game farmers' economic returns were therefore compared with those of beef cattle producers. Investment per hectare was found to be comparable. Game farmers invest more in fencing and more in animals, expressed in Rand per animal unit. Gross and net incomes comparable to those of beef farmers can be obtained with game. Returns on capital are also comparable but low, neither game nor beef cattle farming appear to be attractive fields for investment. Game farming appears to be more risky than beef production. Game farmers should devote more attention to financial management and records.

We prove the connection of purity to observable quantities for these states, and show that the joint measurement of two conjugate quadratures is necessary and sufficient to determine the purity at any time. The statistical reliability and the range of applicability of the proposed measurement scheme is tested by means of Monte Carlo simulated experiments. We then consider the dynamics of purity in noisy channels. We derive an evolution equation for the purity of general Gaussian states both in thermal and squeezed thermal baths. We show that purity is maximized at any given time for an initial coherent state evolving in a thermal bath, or for an initial squeezed state evolving in a squeezed thermal bath whose asymptotic squeezing is orthogonal to that of the input state.

We use a parametrix different from the one employed by in (Dufera, 2019). The system of BDIEs is formulated in terms of parametrix-based surface and volume potentials whose mapping properties are analysed in weighted Sobolev spaces. The system of BDIEs is shown to be equivalent to the original boundary value problem and uniquely solvable in appropriate weighted Sobolev spaces suitable for infinite domains.

description: If quasar jets are accelerated by magnetic fields but terminate as matter dominated, where and how does the transition occur between the Poynting-dominated and matter-dominated regimes? To address this question, we study constraints which are imposed on the jet structure by observations at different spatial scales. We demonstrate that observational data are consistent with a scenario where the acceleration of a jet occurs within 10^{3-4} R_g. In this picture, the non-thermal flares -- important defining attributes of the blazar phenomenon - are produced by strong shocks formed in the region where the jet inertia becomes dominated by matter. Such shocks may be formed due to collisions between the portions of a jet accelerated to different velocities, and the acceleration differentiation is very likely to be related to global MHD instabilities.

description: We study the finite temperature free energy and fermion number for Dirac fields in a one-dimensional spatial segment, under two different members of the family of local boundary conditions defining a self-adjoint Euclidean Dirac operator in two dimensions. For one of such boundary conditions, compatible with the presence of a spectral asymmetry, we discuss in detail the contribution of this part of the spectrum to the zeta-regularized determinant of the Dirac operator and, thus, to the finite temperature properties of the theory.

description: Lately, several firms have decoupled audit and tax service providers to shore up the credibility of their financial statements. However, a number of other firms rely on the incumbent auditor for tax services. Do investors assign a lower valuation to firms that continue to use the auditor for tax services? We contribute to the literature by examining whether auditor-provided tax services moderate investor perception of earnings. We find that the value-relevance of earnings is increasing in the ratio of tax fees over total fees paid to the auditor. Further, for a sample of firms that switched to other providers of tax services, we find that the value-relevance of earnings is lower in the year of the switch. These findings support the notion that on average, investors perceive the benefits of auditor-provided tax services, i.e., enhanced financial reporting quality due to knowledge spillover to be greater than the likely threat to auditor independence caused by auditor-provided tax services. Our findings have important implications for audit committee chairs, managers, and regulators.
Do models of discretionary accruals detect actual cases of fraudulent and restated earnings? An empirical evaluation

description: We examine the association between the existence and the magnitude of a fraudulent event, non- fraudulent restatements of financial statements, and nine competing models of discretionary accruals, accrual estimation errors (Dechow and Dichev 2002 and McNichols 2002), and the Beneish (1999) M-score. We use the size of the downward earnings restatement following the discovery of the fraud to proxy for the degree of discretion exercised to perpetrate the fraud. We find that while total accruals are associated with the existence of fraud, discretionary accruals derived from the Jones model, the modified Jones model, and performance-matched models are not associated with fraud. Accrual estimation errors and M-score have explanatory power for fraud beyond total accruals. We also find that commonly used measures of discretionary accruals, accrual estimation errors, and the M-score are associated with the magnitude of the fraud. Only the accrual estimation errors are associated with non-fraud restatements.

description: Futures trading serves a useful economic purpose because, in an uncertain world, someone must assume a speculative role for there to be production and distribution. An economy based on private property gives people leeway in what they choose to own. One's choice is dictated by many considerations including alternative opportunities to produce and to invest. A key point is that a producer's capital commitments (ownership) for production can be lessened by renting durable assets or by contracting with others to provide needed services. Whoever owns the durable or single-use goods assumes the responsibility for any gains or losses arising out of the changing market value of these goods. In agriculture, forward contracts are a major way to shift ownership responsibility for commodities on to different people or firms. A futures contract is nothing more than a particular type of forward contract, namely one that is traded under special rules and regulations of an organised commodity exchange and the Government, and each contract for a particular commodity and market place is identical. There is little or nothing that can be accomplished through organised futures trading in a commodity that cannot be accomplished without it. However, the costs and inconvenience are often much less through futures trading if the market is functioning properly. The protection of their own interests by farmers may prohibit the proper development of futures markets in the Republic of South Africa.

Non-Linearity Corrections and Statistical Uncertainties Associated with Near-Infrared Arrays

description: We derive general equations for non-linearity corrections and statistical uncertainty (variance) estimates for data acquired with near-infrared detectors employing correlated double sampling, multiple correlated double sampling (Fowler sampling) and uniformly-spaced continuous readout techniques. We compare our equation for the variance on each pixel associated with Fowler sampling with measurements obtained from data taken with the array installed in the near-infrared cross-dispersed spectrograph (SpeX) at the NASA Infrared Telescope Facility and find that it provides an accurate representation of the empirical results. This comparison also reveals that the read noise associated with a single readout of the SpeX array increases with the number of non-destructive reads, n_r, as n_r^0.16. This implies that the {effective} read noise of a stored image decreases as n_r^-0.34, shallower than the expected rate of n_r^-0.5. The cause of this read noise behavior is uncertain, but may be due to heating of the array as a result of the multiple read outs. Such behavior may be generic to arrays that employ correlated or multiple correlated double sampling readouts.

Does accounting and financial expertise in the c-suite aid or mitigate earnings management?

description: Despite the obvious impact of the CFO and the CEO on a firm’s financial statements, there is limited empirical evidence on whether and how the personal characteristics of senior management are associated with earnings management. We provide empirical evidence on the relation between earnings management and the accounting and financial expertise of these C-suite managers. For a sample of S&P 500 firms we find that CEOs and CFOs with accounting and financial expertise appear to manage earnings more aggressively than CEOs and CFOs without such expertise. We document greater earnings management by C-suite managers with accounting/financial expertise via accruals as well as real activities, such as overproducing goods, cutting back on discretionary spending, such as advertising and research and development expenses, manipulating sales and shifting of core expenses to special items. Our findings have important implications for boards of directors, members of the audit committee, investors and others.

description: Fractured tonotopy of functional neural clusters in mouse auditory cortex
The degree of order versus randomness in mammalian cortical circuits has been the subject of much discussion. Previous reports showed that at a large scale there is smooth tonotopy in mouse auditory cortex, while at the single neuron level the representation is the traditional “salt and pepper” configuration attributed to rodent cortex. Here we show that at the micro columnar scale we find a large variety of response profiles, but neurons tend to share similar preference in terms of frequency, bandwidth and latency. However, this smooth representation was fractured and large di↵erences were possible between neighbouring neurons. Despite the tendency of most groups of neurons to operate redundantly, high information gains were achieved between cells that had a high signal correlation. Connectivity between neurons was highly non-random, in agreement with a previous in-vitro report from layer five. Our results suggest the existence of functional clusters, connecting neighbouring mini-columns. This supports the idea of a ”salt and pepper” configuration at the level of functional clusters of neurons rather than single units.

description: Scenario 7 of the UBC Food System Project seeks to apply benchmarks to previously established indicators in order to gauge progress towards conforming to the model of sustainability of the project. It involves 28 indicators from previous AGSC 450 coursework, and several new indicators that came to light during our work. The indicators focus on progress by the four major partners of the UBCFS, outlined below. Work was divided among three research groups, and results were shared. We approached the four partners to find specific data pertaining to the indicators, attempting to find historical data from 2000, current data, and realistic goals for 2010. We created a model to incorporate the indicators and benchmarks into the currently defined model of sustainability. Finally we make suggestions on how to streamline the benchmarking process in the future.
