title: Role of neurosteroids on memory formation in the chick
Creators: name: Migues, Paola Virginia
Publisher: name: The Open University
Year: 2001

description: In this study the presence and possible synthesis of the neurosteroids pregnenolone- sulphate (PREG-S), pregnenolone (PREG), dehydroepiandosterone-sulphate (DHEA-S) and dehydroepiandosterone (DHEA) in the day-old chick brain and their possible role in memory formation have been investigated.
 Radioimmunoassay analyses indicated that PREG-S, PREG, DHEA-S and DHEA are present in the chick brain at higher concentrations than in the plasma. Immunocytochemical studies also showed that the enzyme that catalyses the synthesis of PREG, cytochrome P450scc, is present in the chick brain and is located in neurons but not in astrocytes.
 Training on the strong version of the passive avoidance task (100% methylanthranilate; MeA) increased the concentration of PREG-S in the LPO but not in the IMHV, in females only. The concentrations of PREG, DHEA-S or DHEA in both the IMHV and LPO remained unchanged in both sexes. Basal levels of PREG and DHEA in the IMHV were much higher than in the LPO and the whole forebrain. However, there was a difference in the basal concentration of PREG-S in the IMHV between the sexes; females had higher concentrations of PREG-S than males.
 When injected bilaterally into the brain PREG-S (0.004-400 ng) and PREG (0.003-300 ng) enhanced memory retention for the weak version of the passive avoidance task (10% MeA) but the range of effective doses and the time windows for their memory enhancing effect were different for females and males. DHEA-S (0.004-400 ng) and DHEA (0.003-300 ng) also enhanced memory retention but, unlike PREG-S and PREG, their effects were similar for both sexes.

description: Boundary layers in space and astrophysical plasmas are the location of complex dynamics where different mechanisms coexist and compete eventually leading to plasma mixing. In this work, we present fully kinetic Particle-In-Cell simulations of different boundary layers characterized by the following main ingredients: a velocity shear, a density gradient and a magnetic gradient localized at the same position. In particular, the presence of a density gradient drives the development of the lower hybrid drift instability (LHDI), which competes with the Kelvin-Helmholtz instability (KHI) in the development of the boundary layer. Depending on the density gradient, the LHDI can even dominate the dynamics of the layer. Because these two instabilities grow on different spatial and temporal scales, when the LHDI develops faster than the KHI an inverse cascade is generated, at least in 2D. This inverse cascade, starting at the LHDI kinetic scales, generates structures at scale lengths at which the KHI would typically develop. When that is the case, those structures can suppress the KHI itself because they significantly affect the underlying velocity shear gradient. We conclude that depending on the density gradient, the velocity jump and the width of the boundary layer, the LHDI in its nonlinear phase can become the primary instability for plasma mixing. These numerical simulations show that the LHDI is likely to be a dominant process at the magnetopause of Mercury. These results are expected to be of direct impact to the interpretation of the forthcoming BepiColombo observations.

description: We construct a phenomenological conformal field theory (CFT) model of the three-dimensional Hawking-Page transition. We find that free fermion CFT models on the boundary torus give a description of the three-dimensional Hawking-Page transition. If modular invariance is respected, the free fermion model implies that the transition occurs continuously through the conical space phase and the small black hole phase. On the other hand, if we are allowed to break modular invariance, we can construct a free fermion model that reproduces the usual Euclidean semi-classical result, and in particular exhibits a first-order phase transition.

We demonstrate that large domains of quantum fluids support long-wavelength neutral collective excitations with well-defined wave vector (momentum) dispersion that could be interpreted by theories for uniform phases. Access to dispersive low-lying neutral collective modes in large domains of FQHE fluids such as long wavelength magnetorotons at filling factor v=1/3 offer significant experimental access to strong electron correlation physics in the FQHE.

description: Understanding the pricing process in agricultural spot and futures markets is important for every market participant. In this article we analyse price discovery in the European wheat market based on the partial cointegration approach recently introduced by Clegg and Krauss (2017). Partial cointegration allows for not only transient but also persistent shocks to the long-run equilibrium relationship between two or more variables. By combining the concept of partial cointegration with state space modelling we are able to generate time-variant price discovery metrics that allow for shifts in the long-run relationship between futures and spot prices, for example due to changes in the quality composition of the wheat harvest from year to year, or due to changes in the specification of the futures contact. We find that price discovery is in general dominated by the futures market but that the spot market takes on greater significance for the pricing process during phases of higher price volatility. We also find evidence that the persistent shocks the long-run relationship between spot and futures prices estimated by the partial cointegration method are affected by the availability of high-quality wheat on the spot market.

description: In this paper we present farmer evaluation of a dominant male sterile gene – Ms44 – for maize varieties in Kenya. More than 1000 farmers, 58% women, evaluated the varieties in 8 sites. Our results show that farmers have a wide range of criteria they use in evaluating maize varieties. These criteria do include tassel formation and pollen shed, for which they score Ms44 varieties lower than their conventional counterparts in the mid-season evaluation. This clearly shows farmers can distinguish the male sterility trait at midseason. They still preferred the Ms44 varieties over the others during the mid-season evaluation, because of higher scores on other criteria, inlcuding yield. At the end-season evaluation, tassel formation in Ms44 varieties does not receive a lower score, indicating the trait is no longer observable at harvest. On the methods, asking farmers about different criteria does affect their evaluation, so this type of studies needs to be carefully designed, as demonstrated here. Farmers tend to state many criteria as importance, while not making much distinction between them. Regression overall evaluation over evaluations of different individual criteria, however, shows a more nuanced story. Again, including different criteria affect the weight of the other criteria.

description: Density is one of the most important properties of seawater and is used in various marine research and technology. Traditionally, in the practice of oceanographic research, it is customary to con-sider density as a dependent parameter, which is a function of several other parameters taken as independent. Usually the following three parameters are used as the independent parameters: temperature, hydrostatic pressure and salinity. The issues of temperature and hydrostatic pressure measuring in situ are technologically well developed, while in the salinity measuring there are still unsolved problems. This is due to the fact that salinity is such a property that it is simply impossi-ble to determine directly in situ. To eliminate the problems associated with measurements of sa-linity, the authors developed the special new kind equation. That equation of the new kind ex-press the density of sea water through independent and in situ measured parameters: temperature, hydrostatic pressure and sound speed. The novelty of this approach is that using of the sound speed as the independent parameter makes it possible to exclude measurements of salinity. The authors developed two such new equations for the different cases of using. The first new equa-tion is intended for use in technical applications and reproduces the sea water density in a wide range of the aquatic environment parameters with a root mean square deviation of 0.062 kg/m3. The second more precise new equation is intended for scientific applications and reproduces the sea water density in a narrower oceanographic range of parameters with a root mean square devi-ation of 0.0018 kg/m3.

title: Accretion Flow and Precession Phenomena in Cataclysmic Variables
Creators: name: Rolfe, Daniel James
Publisher: name: The Open University
Year: 2001

description: Cataclysmic variables are interacting binaries where the accretion flow is usually the dominant source of emission. They provide a valuable opportunity to study accretion, the most potent source of energy in the universe. This thesis presents optical studies of two such systems, V348 Pup and IY UMa, providing new insights into a variety of accretion phenomena.

V348 Pup has a'persistently hot accretion disc, while in IY UMa the disc undergoes a series of outbursts in which it changes from a cool state to a much hotter, brighter state. We view both systems from close to the plane of the disc, making it possible to employ indirect imaging techniques to map both the spatial and velocity distributions of accretion flow.

V348 Pup harbours a precessing asymmetric disc, as does IY UMa during superoutburst, leading to a super hump modulation in luminosity as the companion tidally interacts with the precessing disc. The disc shape in IY UMa as it shows ‘late’ superhumps at the end of a superoutburst is found, and a simple model reveals varying energy dissipation at the stream-disc impact to be the source of the late superhumps. This study finds that this might also be the mechanism producing the superhumps in V348 Pup.

Spectroscopy reveals that V348 Pup is an SW Sex type star, where anomalous line emission is dominated by a source other than the accretion disc. This study supports the model in which some of the accretion stream overflows the disc and is expelled from the system by a magnetic propeller anchored in the disc.

Spectroscopy of IY UMa during outburst reveals rapidly changing accretion flow, with reprocessing of radiation in the outer disc and on the companion star, and possibly spiral shock waves in the disc. Quiescent observations reveal absorption features from the donor star, along with emission from the stream-disc impact and accretion disc.

description: Electrostatic interactions make a large contribution to solvation free energy in ionic fluids such as electrolytes and colloidal dispersions. The electrostatic contribution to solvation free energy has been ascribed to the self-energy of a charged particle. Here we apply a variational field theory based on lower bound inequality to the inhomogeneous fluids of one-component charged hard-spheres, thereby verifying that the self-energy is given by the difference between the total correlation function and direct correlation function. Based on the knowledge of the liquid state theory, the self-energy specified in this study not only relates a direct correlation function to the Gaussian smearing of each charged sphere, but also provides the electrostatic contribution to solvation free energy that shows good agreement with simulation results. Furthermore, the Ornstein-Zernike equation leads to a new set of generalized Debye-Hückel equations reflecting the Gaussian distributed charges.

description: Shock-induced metamorphism in meteorites informs us about the collisional environment and history of our solar system. Recently the importance of material strength in impact heating was reported from head-on impact simulations. Here, we perform three-dimensional oblique impact simulations, and confirm the additional heating due to material strength for oblique impacts. Despite a large difference in the peak pressure at the impact point at a given impact velocity, we find that the heated mass for an oblique impact is nearly the same as that for a head-on impact. Thus, our results differ from the previous finding that the heated mass decreases as the impact becomes more oblique, and show that the additional shear heating is more effective for oblique impacts than for head-on impacts. This also indicates that material ejected during oblique impact tends to experience lower shock pressures but higher temperatures.

description: In this article we study a constant-roll inflationary model in the context of brane-world cosmology caused by a quintessence scalar field for warm inflation with a constant dissipative parameter Q =$\Gamma$/3H. We determine the analytical solution for the Friedman equation coupled to the equation of motion of the scaler field. The evolution of the primordial scalar and tensor perturbations is also studied using the modified Langevin equation. To check the viability of the model we use numerical approaches and plot some figures. Our results for the scalar spectral index and the tensor to scaler ratio show good consistency with observations.

description: This paper examines the empirical link between smallholder vegetable production and the dietary diversity of children aged 0.5 to 17 years at the household level through: vegetable diversity, market engagement, and gender-related factors. We use Child Dietary Diversity Score (CDDS) as measure of children’s diets. We find that market access and market participation can significantly improve CDDS, especially for older boys >5 to 17 years. For children under five years, improving the nutritional knowledge of the food preparer, promoting market linkage to increase income, and implementing intervention targeted on the low-lying and low vegetable per capita density areas can improve diet quality.
Equations of Camassa--Holm type and Jacobi elliptic coordinates

description: We consider the integrable Camassa--Holm equation on the line with positive initial data rapidly decaying at infinity. On such phase space we construct a one parameter family of integrable hierarchies which preserves the mixed spectrum of the associated string spectral problem. This family includes the CH hierarchy. We demonstrate that the constructed flows can be interpreted as Hamiltonian flows on the space of Weyl functions of the associated string spectral problem. The corresponding Poisson bracket is the Atiyah--Hitchin bracket. Using an infinite dimensional version of the Jacobi ellipsoidal coordinates we obtain a one parameter family of canonical coordinates linearizing the flows.

description: Cold data storage systems are used to allow long term digital preservation for institutions' archives. The common functionality among cold and warm/hot data storage is that the data is stored on some physical medium for read-back at a later time. However in cold storage, write and read operations are not necessarily done in the same exact geographical location. Hence, a third party assistance is typically utilized to bring together the medium and the drive. On the other hand, the reliability modeling of such a decomposed system poses few challenges that do not necessarily exist in other warm/hot storage alternatives such as fault detection and absence of the carrier, all totaling up to the data unavailability issues. In this paper, we propose a generalized non-homogenous Markov model that encompasses the aging of the carriers in order to address the requirements of today's cold data storage systems in which the data is encoded and spread across multiple nodes for the long-term data retention. We have derived useful lower/upper bounds on the overall system availability. Furthermore, the collected field data is used to estimate parameters of a Weibull distribution to accurately predict the lifetime of the carriers in an example scale-out setting. In this study, we numerically demonstrate the significance of carriers' presence and the key role that their timely maintenance plays on the long-term reliability and availability of the stored content.

description: As identified by the Climate Action Plan (CAP) 2030 published by the University of British Columbia (UBC), there is a need to develop Climate-Friendly Food Systems (CFFSs) on campus to reduce campus greenhouse gas (GHG) emissions (University of British Columbia, 2021). The UBC Social Ecological Economic Development Studies (UBC SEEDS) is developing a toolkit that can enhance awareness and drive action toward CFFSs among the UBC community. Factors influencing food choices at UBC should be taken into account by the CFFS Toolkit to maximize its impact. The main barrier to sustainable choices that will be addressed by the Toolkit is the lack of knowledge preventing people from making informed choices. However, many students have priorities besides sustainability when obtaining food that needs to be reconciled by the Toolkit (Chiam et al., 2021). Luckily, there are also many strengths at UBC that support sustainable food choices that can be highlighted by the Toolkit, including food asset maps, student initiatives, and sustainable food markets. The overall goal of the current project is to support UBC SEEDS in the development of the CFFS Toolkit. The outputs of our group include the feedback from group members regarding the CFFS Student Survey and the CFFS Toolkit contents, as well as a final guidance document identifying effective communication methods and barriers of sustainable food choices to the UBC students. The outputs focus on maximizing the effectiveness of the CFFS Toolkit, based on the chosen theory framework, the Diffusion of Innovation Theory. Our outputs directly target the UBC SEEDS team to advance further the indirect output, the CFFS Toolkit, of which the UBC community is the target audience. To evaluate the completion of our guidance document, we compared it to other sustainability guidelines already written for the UBC community. We also will meet with SEEDS to discuss if our deliverable met their expectations and if it was easy to implement and understand. Once the Toolkit is published, a comparison of the finished product to our guidance document will reveal the degree to which our recommendations are reflected in the Toolkit. Namely, if the identified barriers to sustainable eating are addressed by the Toolkit and if it uses the recommended language and messaging styles. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC. Furthermore readers should bear in mind that these reports may not reflect the current status of activities at UBC. We urge you to contact the research persons mentioned in a report or the SEEDS Coordinator about the current status of the subject matter of a project/report.”

description: Rapid agricultural growth causes substantial increase in the rural non-farm expenditure on the rural non-farm sector that eventually increases the rate of growth of market towns and hence a dispersing of urbanization away from the small number of large urban centers. That effect is greater for low income countries than middle income countries. Thus, the effect in low income countries sets the stage for longer term dispersion of urbanization. Rapid agricultural growth is the major cause of poverty decline in both low and middle income countries. The impact is greatest when it starts as a low income country and continues in middle income status. One of the down sides to modernization of agriculture is the common exclusion of women, including farmer s wife s, from reedy access to the new information require to take advantage of income increasing technological change in agriculture. The problem is easily solved by making extension demonstration the core of information spread and ensuring participation of farmer s wife s ae well as female headed farm households. That inclusion then facilitates women playing a major leadership role on the institutions of modernization such as rural cooperatives. Acknowledgement :
Integrated Micro-Macro Structural Econometric Framework for Assessing Climate-Change Impacts on Agricultural Production and Food Markets

description: This paper combines a micro-level structural econometric model of farmland allocation and a market-level equilibrium supply-demand model in order to simulate the effects of climate changes on agricultural production, food prices and social welfare. The estimation accounts for corner solutions associated with disaggregated land-use data, whose usage enables treating prices as exogenous. We employ the model for assessing climate-change impacts in Israel, in which agriculture is protected by import tariffs. We find that projected climate changes are beneficial to farmers, particularly due to the positive impact of the forecasted temperature rise on field crops. Fruit production are projected to decline, and reduce consumer surpluses, but to a lower extent than the increase in total agricultural profits. Nearly 20% of the profit rise is attributed to farmers adaptation through land reallocation. Adaptation to the projected reduction in precipitation by increasing irrigation is found warranted from farmers perspective; however, it is not beneficial to society as a whole. Abolishing import tariffs effectively transfers surpluses from producers to consumers, but its impact on social welfare becomes positive only under large climate changes. Acknowledgement :

Control of spin waves by spatially modulated strain

Year: 2022
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We suggest using spatially modulated strain for control of a spin wave propagating inside a bulk magnet. The modulation with the wave vector $q=2k$, by virtue of magnetoelasticity, mixes spin waves with wave vectors near $k$ and $-k$. This leads to lifting the degeneracy of the symmetric and antisymmetric eigenstate combinations of these waves. The resulting picture reminds one of a tunneling particle in a symmetric double-well potential. Here, a moving spin wave being subjected to the $2k$-lattice modulation after some time alters its propagation direction to the opposite one, and so on. The effect can be utilized for the control of the spin-wave propagation that can be useful for spintronic and magnonic applications. The control may include a delay line element, filtering, and waveguide of the spin waves.

description: We obtain the enropy of Schwarzschild and charged black holes in D>4 from superconformal gases that live on p=10-D dimensional brane-antibrane systems wrapped on T^p. The preperties of the strongly coupled superconformal theories such as the appearance of hidden dimensions (for p=1,4) and fractional strings (for p=5) are crucial for our results. In all cases, the Schwarzschild radius is given by the transverse fluctuations of the branes and antibranes due to the finite temperature. We show that our results can be generalized to multicharged black holes.
