Publisher: name: Journal of Science and Sustainable Development
Year: 2016

description: This study was undertaken in 2014 at Ambo University Department of Biology to assess growth, yield, yield parameters and biological efficiency of oyster mushroom (Pleurotus ostreatus). Four treatments T1 (10: 80: 10; teff straw: waste paper: cotton seed waste), T2 (20:60:20; teff straw, waste paper and cotton seed waste), T3 (30:40:30 Teff straw: waste paper: cotton seed waste) and T4 (33.3:33.3:33.3; Teff straw, waste paper and cotton seed waste) were evaluated in three replication using complete randomize block design. Results showed that T4 (33.3:33.3:33.3; Teff straw: waste paper : cotton seed waste) recorded the fastest mycelial extension followed by T3 (30:40:30 Teff straw: waste paper : cotton seed waste) while, T1 (10:80:10; teff straw: waste paper : cotton seed waste) exhibited the slowest mycelial extension on 7th and 14th days of incubation periods. T1 (10:80:10; teff straw: waste paper: cotton seed waste) took longer incubation periods from pinning to maturation while T4 took shorter periods from pinning to maturation in all flushes. Relatively highest and equal numbers of fruiting bodies were collected fromT1 (10:80:10; teff straw: waste paper: cotton seed waste), T2 (20:60:20; teff straw, waste paper and cotton seed waste) and T4 (33.3:33.3:33.3; Teff straw, waste paper and cotton seed waste), While T3 (30:40:30 Teff straw: waste paper: cotton seed waste) gave the least number of fruiting bodies. Pilus diameter was largest for T3 followed by T2 and T1 respectively. The stipe length of mushroom for all treatments did not varied significantly. The highest total fresh weight of matures and biological efficiency was recorded in T4 followed by T3 and the least on T1 (10:80:10; teff straw: waste paper: cotton seed waste). The result of this study showed the possibility of obtaining high yield and more biological efficiency by preparing equal proportion of teff straw, waste paper and cotton seed waste and hence recommend for further verification studies and scale up for commercial production of the oyster mushroom.

ATM-deficient cancer cells and targeted therapies

description: The driving principle behind precision medicine is to specifically target genetic variations that arise in tumorigenesis while leaving normal cells unaffected. Mutations in Ataxia Telangiectasia Mutated (ATM) may offer such a therapeutic target. ATM is mutated in a variety of tumor types and these mutations can lead to a dysfunctional protein, or protein deletion. ATM is an apex signaling kinase that responds to DNA double strand breaks, playing a direct role in DNA repair as well as the initiation of signaling cascades that can lead to cell cycle arrest and apoptosis. In recent years, several studies have shown that Poly ADP-Ribose Polymerase (PARP) inhibitors effectively target ATM-deficient tumors both invitro and invivo. These studies have been limited to mantle cell lymphoma, gastric cancer, colorectal cancer and breast cancer cell lines and the mechanism of sensitivity remains unclear. Here, I show that ATM-deficient lung and pancreatic cancer cell lines are sensitive to olaparib (a PARP inhibitor) and that ATM-deficient pancreatic cancer cell lines are sensitive to the PARP inhibitor Rucaparib as well as the ATR inhibitor VE-821. Using both lung and colorectal cancer cells, I also show that olaparib induces DNA damage and that olaparib causes an accumulation of G2 phase cells in ATM-deficient cells. Since olaparib is set to become a more commonly used chemotherapeutic, these findings are both important and relevant to its use in the clinic.
Identification and estimation of structural VAR and MARMA models

Subjects: Economics

description: In this paper we give an integrated presentation of the theory of structural VAR and MARMA (multivariate autoregressive moving average) models. We determine the conditions under which such models are identified, and give the limiting distribution of the resulting estimators. In additions, we impose the requisite restrictions by means of LaGrange multipliers, and provide easily implementable test for overidentifying restrictions. Moreover, it is argued that a just identified structural VAR model does not convey and information on the economic structure of the VAR. Finally, this development is extended to structural MARMA models.

description: We consider the semiconjugate factorization and reduction of order for non-autonomous, nonlinear, higher order difference equations containing linear arguments. These equations have appeared in several mathematical models in biology and economics. By extending some recent results to cases where characteristic polynomials of the linear expressions have complex roots, we obtain new results on boundedness and the existence of periodic solutions for equations of order 3 or greater.

description: In 2015 the National Spinal Cord Injury Association of Canada reported that 30,000 Canadians suffer from paralysis in two or more limbs. In many cases this takes away the fundamental ability to walk. Walking, an intricate sensorimotor task, involves the interactions of both dynamic and balancing neurological processes. Brain computer interfaces (BCIs) are attempting to bridge the gap that will allow persons with compromised mobility to interact with the world via control of prosthetic devices that can ‘act’ by using solely neural input (i.e. thoughts). The goal of this thesis was to aid in the development of a BCI for lower limb locomotion by identifying similarities and differences between cortical activity associated with executed and imagined left and right lower limb movements using electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI). Data from 16 participants showed that it was possible to differentiate between right versus left executed and imagined thought processes for lower limb locomotion using solely information from an EEG, and that these patterns of brain activity were generalizable across time points and trials. It was also found, through the use of fMRI, that areas of brain activation in executed and imagined conditions were similar for some areas but showed unique activation areas as well. A novel paradigm to co-register EEG and fMRI data was developed that can easily be utilized in other contexts. Finally, using EEG and fMRI data allowed for an efficient model to use in a machine learning paradigm that successfully predicted left versus right lower limb movement. This research adds to the existing body of knowledge in understanding psychomotor brain activity associated with thought coordination processes involved in the task of walking in normal persons represented by algorithmic patterns.

Investigation for improvement and application of MEMS-based micro-electro-discharge machining (M3EDM)
Creators: name: Wang, Ningyuan
Publisher: name: University of British Columbia
Year: 2011

description: MEMS-based micro-electro-discharge machining (M3EDM) is a batch microfabrication technique utilizing planar electrode actuators to machine conductive materials. The low contrast pattern transfer issue in electroplating mold fabrication is firstly analyzed and improved by eliminating the contact gap and adding a rehydration step. The new method gives a better structure profile with near vertical sidewalls. The causes and mechanisms of spin coating non-uniformity and bonding voids are discussed, as well. The deformation on the foil electrode area where discharges occur is explained by abnormal heat shock, tool wear, material softening and discharge-brought reactive force. A feedback control circuit with pulse discrimination is developed to detect the harmful short pulse and prevent thermal shock. Nickel is proposed and tested as the new material for actuators owing to its higher mechanical and thermal resistance. The optimized nickel based electrodes together with the affiliation circuit are applied to cantilever MEMS contact switch fabrication. The photoresist melting in the photoresist sandwich structure is observed. A new reverse fabrication process is proposed and processed in order to minimize the photoresist melting. The method partially addresses the issue. The further directions for improvements and the potential application of the reverse process to reusable M3EDM devices are discussed.

description: We study ring shaped (Corbino) devices made of bilayer two-dimensional electron gases in the total filling factor one quantized Hall phase which is considered to be a coherent BCS-like state of interlayer excitons. Identical Josephson currents are observed at the two edges while only a negligible conductance between them is found. The maximum Josephson current observed at either edge can be controlled by passing a second interlayer Josephson current at the other edge. Due to the large electric resistance between the two edges, the interaction between them can only be mediated by the neutral interlayer excitonic groundstate.

description: The single-freeze-out model with parametrized hypersurface and flow geometry is employed to analyze the transverse-momentum spectra of hadrons produced in the Pb+Pb collisions at the collision energy of {$\sqrt{s_{\rm NN}}=2.76$ TeV} at the CERN Large Hadron Collider (LHC). With the notable exception for protons and antiprotons, we find a very good agreement between the model results and the data for the measured hadron species. The additional analysis of the HBT radii of pions helps us to select, from several different types of freeze-out studied in this work, the most realistic form of the freeze-out hypersurface. We find that discrepancy ratio between the model and experiment for the proton/antiproton spectra depends on $p_T$, dropping from 2 in the soft region to 1 around $p_T=1.5$ GeV.

The long range dependence paradigm for macroeconomics and finance

Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: The long range dependence paradigm appears to be a suitable description of the data generating process for many observed economic time series. This is mainly due to the fact that it naturally characterizes time series displaying a high degree of persistence, in the form of a long lasting effect of unanticipated shocks, yet exhibiting mean reversion. Whereas linear long range dependent time series models have been extensively used in macroeconomics, empirical evidence from financial time series prompted the development of nonlinear long range dependent time series models, in particular models of changing volatility. We discuss empirical evidence of long range dependence as well as the theoretical issues, both for economics and econometrics, such evidence has stimulated.

Conventional and Unconventional Monetary Policy

Subjects: Economics

description: We extend a standard New Keynesian model to incorporate heterogeneity in spending opportunities and two sources of (potentially time-varying) credit spreads, and to allow a role for the central bank's balance sheet in equilibrium determination. We use the model to investigate the implications of imperfect financial intermediation for familiar monetary policy prescriptions, and to consider additional dimensions of central-bank policy—variations in the size and composition of the central bank's balance sheet, and payment of interest on reserves—alongside the traditional question of the proper choice of an operating target for an overnight policy rate. We also give particular attention to the special problems that arise when the zero lower bound for the policy rate is reached. We show that it is possible to provide criteria for the choice of policy along each of these possible dimensions, within a single unified framework, and to provide policy prescriptions that apply equally when financial markets work efficiently and when they are subject to substantial disruptions, and equally when the zero bound is reached and when it is not a concern.

description: The purpose of this study was to identify the potentials and challenges of promotion of smallholder fish farming based on the experiences of south west and West Shewa zones of Oromia region. Therefore, primary data were generated using both rapid appraisal methods mainly based on focus group discussion (FGDs) and Key Informant Interviews (KII) in addition to formal survey using pre-tested questionnaire from randomly selected 34 Smallholder fish farming households. The data was summarized using mainly descriptive and approaches. Cost of fish feed, lack of awareness, extension and advisory services, lack of relevant expertise and private investment had been identified as challenges for the development of small scale fish farming in the study areas. Therefore, further gender disaggregated trainings based on their responsibility should be given to create awareness. Research centers should take full package technologies and try to do on farm evaluation before releasing to individual users. To involve private sectors in this sub-sector and also to encourage farmers the government should develop aquaculture stimulus package which will create various actors along the value chain

Asymptotic Equivalence of Probabilistic Serial and Random Priority Mechanisms
Creators: name: Che, Yeon-Koo

Year: 2008
Subjects: Economics

description: The random priority (random serial dictatorship) mechanism is a common method for assigning objects to individuals. The mechanism is easy to implement and strategy-proof. However this mechanism is inefficient, as the agents may be made all better off by another mechanism that increases their chances of obtaining more preferred objects. Such an inefficiency is eliminated by the recent mechanism called probabilistic serial, but this mechanism is not strategy-proof. Thus, which mechanism to employ in practical applications has been an open question. This paper shows that these mechanisms become equivalent when the market becomes large. More specifically, given a set of object types, the random assignments in these mechanisms converge to each other as the number of copies of each object type approaches infinity. Thus, the inefficiency of the random priority mechanism becomes small in large markets. Our result gives some rationale for the common use of the random priority mechanism in practical problems such as student placement in public schools.
Estimating ambiguity
Creators: name: Henry, Marc
Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: We propose a measure of the degree of ambiguity associated with a belief function and a nonparametric method to estimate it. The degree of ambiguity associated with a belief function is measured by the Kullback-Leibler diameter of the set of probability measures compatible with it. It is shown that an estimator based on the empirical version of the unambiguous measure generating the belief function is consistent for the true value of the ambiguity measure. Applications to policy decision making under Knightian uncertainty are discussed.

The origin of the famous Heckscher-Ohlin theorem is the seminal article by Heckscher (1919) in the special 1919 David Davidson Festschrift issue of Ekonomisk Tidskrift, later developed by Ohlin in his doctoral dissertation (1924) and his monumental Interregional and International Trade (1933). Together, these three works established the factor proportions approach to international trade.

description: We study the suitability of correlator product states for describing ground-state properties of two-dimensional spin models. Our ansatz for the many-body wave function takes the form of either plaquette or bond correlator product states and the energy is optimized by varying the correlators using Monte Carlo minimization. For the Ising model we find that plaquette correlators are best for estimating the energy while bond correlators capture the expected long-range correlations and critical behavior of the system more faithfully. For the antiferromagnetic Heisenberg model, however, plaquettes outperform bond correlators at describing both local and long-range correlations because of the substantially larger number of local parameters they contain. These observations have quantitative implications for the application of correlator product states to other more complex systems, and give important heuristic insights: in particular the necessity of carefully tailoring the choice of correlators to the system considered, its interactions and symmetries.

description: We use the known soft and collinear limits of tree- and one-loop scattering amplitudes -- computed over a decade ago -- to explicitly construct a subtraction scheme for next-to-next-to-leading order (NNLO) computations. Our approach combines partitioning of the final-state phase space together with the technique of sector decomposition, following recent suggestions in Ref. [1]. We apply this scheme to a toy example: the NNLO QED corrections to the decay of the Z boson to a pair of massless leptons. We argue that the main features of this subtraction scheme remain valid for computations of processes of arbitrary complexity with NNLO accuracy.

The structural characterizations of the isolated compounds were elucidated by spectroscopic data and comparison with the literatures. Bioassays showed that the isolated capsaicinoids significantly reduced the radical length of Lactuca sativa seedling, this inhibition being dose-dependent.

description: This paper contributes to the debate on the role of anthropological expertise in the legal sphere by broadening the analytical field of vision. Rather than focusing on the anthropologist, his or her positionality, the epistemic status of anthropological knowledge or the ensuing ethical questions – as the other contributions to this themed section do – we turn the question around. Based on empirical data from a survey conducted among European judges on judiciary practice and sociocultural diversity, our focus here is on the question of how judges perceive, assess and accommodate sociocultural diversity in their daily decision-making. We furthermore investigate the conditions under which external expertise is called upon in specific legal settings and situations. We develop a conceptual argument for rethinking the role of anthropological knowledge and research in legal practice and argue for the need to pursue new forms of collaborative ethnography with judges that go beyond participant observation of their courtroom interactions. Working together with the judges who give decisions on cases, we claim, can provide scope for both critical reflection and applied problem-solving.

This is by no means to imply that intra-European or intra-Asian trade was in any sense less significant It is simply a consequence of the limitations of space.

description: This article investigates how the Swedish forest industry, as represented by the three largest Swedish private forest companies (Svenska Cellulosa AB, Stora Enso, and Holmen), through their main public relations (PR) channels frame the current dominant Swedish forestry model and alternative models that are promoted by the European Union (EU). The content analysis of the three companies’ trade magazines published between 2019 and 2022 explores the patterns in the PR framing of the forest management models with respect to economic, environmental, and social aspects. The time interval is centered by the July 2021 announcement of the EU's new Forest Strategy for 2030. The magazines’ target audience is private forest owners, from whom Svenska Cellulosa AB, Stora Enso, and Holmen buy 40–50% of the timber used in production. The main finding of the study is that these corporations did not present alternative methods as viable options to replace the Swedish forestry model. The magazines, with some individual variations, respond to the alternative methods promoted by the EU and environmental associations by an increased emphasis on the benefits, mainly environmental, of the Swedish forestry model – framing the model as not only the most profitable but also the most ecologically sustainable.

description: Micromegas detectors, thanks to the good spatial and temporal discrimination capabilities, are good candidates for rare event search experiments. Recent X-ray background levels achieved by these detectors in the CAST experiment have motivated further studies in the nature of the background levels measured. In particular, different shielding configurations have been tested at the Canfranc Underground Laboratory, using a microbulk type detector which was previously running at the CAST experiment. The first results underground show that this technology, which is made of low radiative materials, is able to reach background levels up to $2 \times 10^{-7}$keV$^{-1}$s$^{-1}$cm$^{-2}$ with a proper shielding. Moreover, the experimental background measurements are complemented with Geant4 simulations which allow to understand the origin of the background, and to optimize future shielding set-ups.

description: It will be only a matter of time before another influenza pandemic occurs. Pandemic flu refers to a novel human influenza virus that causes a global outbreak, or pandemic. Researchers cannot accurately predict the timing, severity, or source of the next pandemic, but are certain it would present a myriad of issues for the public health infrastructures of our local communities. In the case of a pandemic flu outbreak, daily routine would be interrupted and school administrators would have many challenges to face. School principals in particular serve a unique role in their communities -- they are the link between their schools and the outside world, as well as a means of communication between these two sectors. It is important for individuals in this role to be seen as a clear and constant channel of communication at all times, especially during an emergency. In October of 2006, researchers from the National Center for Disaster Preparedness (NCDP), in coordination with the New York City (NYC) based Council of School Supervisors and Administrators (CSA), conducted a web based survey of NYC school principals to gauge their level of preparedness and to address the concern of principals for the many consequences that may arise for their schools if a pandemic flu outbreak is to occur. 330 of the 1260 principals responded (26.2%). Among key findings were the following: 1) 84.1% of principals did not have a pandemic flu plan; 2) Among the few schools with a plan, four out of five principals were not familiar with it; 3) The overwhelming majority of principals said their school had no process for talking with parents, and few have been involved in community level planning efforts. Schools are a resource to the safety of the community, and the well-being of schools and the community are inexorably intertwined. Recommendations for the future center on the need for schools and communities to work together to prepare for pandemic flu, as well as other emergencies. Other important recommendations include improving upon the role of the principal as a risk communicator and integrating the pandemic flu plan into the school's existing safety plan.

description: We provide a test for the specification of a structural model without identifying assumptions. We show the equivalence of several natural formulations of correct specification, which we take as our null hypothesis. From a natural empirical version of the latter, we derive a Kolmogorov-Smirnov statistic for Choquet capacity functionals, which we use to construct our test. We derive the limiting distribution of our test statistic under the null, and show that our test is consistent against certain classes of alternatives. When the model is given in parametric form, the test can be inverted to yield confidence regions for the identified parameter set. The approach can be applied to the estimation of models with sample selection, censored observables and to games with multiple equilibria.
Optimal menu of menus with self-control preferences

Publisher: name: Columbia University
Year: 2004
Subjects: Economics

description: This paper studies how a seller should design its price schedule when consumers' preferences are subject to temptation. As in Gul and Pesendorfer (2001), consumers exercise costly self-control to some degree and foresee their impulsive behavior and self-control. Since consumers may pay a premium for an option set that is less tempting, the seller may offer multiple small menus. Building on the standard model of adverse selection and second-degree price discrimination, we characterize the optimal menu of menus for the seller. In particular, we show that if consumers are tempted by goods of higher quality, the seller can achieve perfect discrimination: consumers' choices appear as if the seller can observe consumers' preferences directly. To achieve this, the seller "decorates" menus by adding items that are never chosen but are tempting to consumers.

description: The values of the fractional distribution of aboveground (AGB) and belowground biomass (BGB), root/shoot ratios (R/S) and stemwood density were estimated for silver (Betula pendula) and downy birch (Betula pubescens) along site index and age gradients for Estonia. Biomass models were used, in which the diameter at breast height (D1.3, measured above root collar), tree height, age and site index served as independent variables. The models for AGB and BGB were elaborated based on the data of 117 and 30 model trees, respectively. Strong allometric relationships were revealed between D1.3 and total AGB (with foliage), stem mass and BGB. For trees with D1.3 < 15 cm, individual models predicted similar biomass patterns for both species, for larger trees, species-specific models are suggested. The relative share of stem mass in AGB was 80–90% for all site index and age classes, being significantly higher for silver birch. The average relative share of stembark, branches, leaves and the R/S, were significantly higher for downy birch. Mean oven-dry mass stemwood density for silver and downy birch was 0.573 g cm−3, there was no statistically significant difference between the species. The mean R/S ratio was 0.29 and 0.43 for silver and downy birch, respectively.

description: We compare the effect of different noise scenarios on the achievable rate of an epsilon-secure key for the BB84 and the six-state protocol. We study the situation where quantum noise is added deliberately, and investigate the remarkable benefit for the finite key rate. We compare our results to the known case of added classical noise and the asymptotic key rate, i.e. in the limit of infinitely many signals. As a complementary interpretation we show that under the realistic assumption that the noise which is unavoidably introduced by a real channel is not fully dedicated to the eavesdropper, the secret key rate increases significantly.

description: Field and laboratory experiments were conducted at Bako Research Center, Western Ethiopia, during 2010/11-2011/12 to evaluate farmers’ traditional practices (layering of tef over sorghum with 20% proportion, mixing sorghum with tef at 30% w/w, mixing sorghum with partially grinded hot pepper at the rate of 2% w/w and 1% w/w) in comparison with Malathion 5% D and untreated check against insect pest of stored sorghum. Similarly, in a laboratory study combinations of different rates of Malathion 5% D (100, 50, 40, 30, 20, 10, 0%) and Neem seed powder (10, 20, 30, 40, 50%) were evaluated against maize weevils from February to - July 2012. Results of the study showed that the number and weight of damaged grains were significantly (p<0.05) higher in layering of tef over sorghum with 20% w/w, mixing sorghum with tef at 30% w/w and untreated check than the other treatments. Similarly, percent weight losses were significantly (p<0.05) lower in mixing sorghum with hot pepper at 2% and 1% w/w than the other treatments, when compared to standard check. Among treatments, mortality in all of the treatment combinations ranged from 3.33 to-100%, while that of the untreated check ranged from 0 to-5.33% following 90 days after infestation. Similarly, the number of progeny weevils emerged, percentages of grain damaged and seed weight losses in all the treatment combinations were significantly lower than that of the untreated check 90 days after infestation. Significantly (P<0.05) higher percentages of mortality, lower percentages were observed for damaged grains and seed weight losses in the Malathion dust at 40% and 50% combined with Neem seed powder than that of the other treatments next to the standard check 156 days after infestation. From these studies, it could be concluded that mixing sorghum with partially grinded chillies (hot pepper) at the rate of 2% w/w or 1% w/w can be used to protect stored sorghum from insect pests and the combinations of Malathion 5% D and Neem seed powder at 40%+20% and 50%+10% respectively, can be used to protect maize from the maize weevil.

Testing for autocorrelation in systems of equations
Creators: name: Dhrymes, Phoebus J.
Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: This paper deals with the problem of testing for the presence of autocorrelation in a system of general linear models (Seemingly Unrelated Regressions, SUR) when the model is formulated as a vector autoregression (VAR) with exogenous variables. The solution presented in this paper is a generalization of the h-statistic for the single equation single parameter case given in Durbin (1970).

description: In the framework of the recently proposed models of massive gravity, defined with respect to a de Sitter reference metric, we obtain new homogeneous and isotropic solutions for arbitrary cosmological matter and arbitrary spatial curvature. These solutions can be classified into three branches. In the first two, the massive gravity terms behave like a cosmological constant. In the third branch, the massive gravity effects can be described by a time evolving effective fluid with rather remarkable features, including the property to behave as a cosmological constant at late time.

Social Security and Equity Investment in an Economy with Financial Intermediaries and Costly Monitoring
Creators: name: Di Giorgio, Giorgio
Publisher: name: Columbia University
Year: 1996
Subjects: Economics

description: This paper aims at extending the analysis of the efficiency of equilibria in an OLG framework with asymmetric information. It focuses on the stationary states of an economy where consumers, firms and financial intermediaries are at work. The process of financial intermediation is affected by ex-post moral hazard due to costly state verification; for this reason, the introduction of social security might be Pareto improving in a market economy even when the economy is dynamically efficient. Moreover, market outcomes are socially inefficient, even when a weaker notion than Pareto optimality is considered. A full characterization of a Constrained Pareto Optimum (CPO) shows that this allocation can never be induced as the result of an optimal policy in a market economy.

Gauge theory approach to glass transitions

Publisher: name: arXiv

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: This theory combines a thermodynamic approach with a dynamic one in order to describe glass transition. Glass transition is regarded as an inaccessible second order phase transition, which is interrupted because of premature critical slowing down, caused by the system's frustration. The frustration-induced vortices are present in the structure besides thermoactivated vortices, and prevent the development of the order parameter fluctuations, that leads to the critical slowing down the system kinetics at some temperature above the phase transition point.
