description: The electric dipole moment (EDM) of a particle violates both time reversal (T) and space reflection (P) symmetries. There have been recent suggestions for searches of the electron EDM using solid state experiments [1,2]. These experiments could improve the sensitivity compared to present atomic and molecular experiments by several orders of magnitude. In the present paper we calculate the expected effect. We also suggest that this kind of experiment is sensitive to T,P-violation in nuclear forces and calculate effects caused by the nuclear Schiff moment. The compounds under consideration contain magnetic Gd$^{3+}$ ions and oxygen O$^{2-}$ ions. We demonstrate that the main mechanism for the T,P-odd effects is related to the penetration of the Oxygen 2p-electrons to the Gd core. All the effects are related to the deformation of the crystal lattice.

description: Travelers’ level of satisfaction is an important performance measure for transport service providers and a determinant of mode choice. However, its computation is not easy because of the complicated and unique characteristics of travelers. The traditional method of comparing yearly satisfaction percentages has been implemented in several places; however, it does not include the interrelationships between variables that determine satisfaction. This study estimates travelers’ level of satisfaction using an ordered logit model and then uses the results in a binary mode choice model. The results show that the level of satisfaction has a significant influence on the modal choice characteristics of travelers.

description: Qualitative research methods are used to examine the status of the “cold chain,” which serves the Mexican market for Canadian food products. A brief synopsis of Canadian food exports to Mexico is presented to establish the demand for refrigerated transport. Subsequently, the supply of refrigerated transport is considered in terms of modal choice and routes from Canada to Mexico. This is followed by a narrative of cold chain challenges identified by industry respondents. The conclusion points to some policy issues for consideration.
On Measuring the Infrared Luminosity of Distant Galaxies with the Space Infrared Telescope Facility

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: The Space Infrared Telescope Facility (SIRTF) will revolutionize the study of dust-obscured star formation in distant galaxies. Although deep images from the Multiband Imaging Photometer for SIRTF (MIPS) will provide coverage at 24, 70, and 160 micron, the bulk of MIPS-detected objects may only have accurate photometry in the shorter wavelength bands due to the confusion noise. Therefore, we have explored the potential for constraining the total infrared (IR) fluxes of distant galaxies with solely the 24 micron flux density, and for the combination of 24 micron and 70 micron data. We also discuss the inherent systematic uncertainties in making these transitions. Under the assumption that distant star-forming galaxies have IR spectral energy distributions (SEDs) that are represented somewhere in the local Universe, the 24 micron data (plus optical and X-ray data to allow redshift estimation and AGN rejection) constrains the total IR luminosity to within a factor of 2.5 for galaxies with 0.4 < z < 1.6. Incorporating the 70 micron data substantially improves this constraint by a factor < 6. Lastly, we argue that if the shape of the IR SED is known (or well constrained; e.g., because of high IR luminosity, or low ultraviolet/IR flux ratio), then the IR luminosity can be estimated with more certainty.

description: The work presented here looks at the commonalities in applying a globally available commercial Augmented Reality (AR) software package in the pursuit of truly differentiated learning. Working within the UK educational system context work has been undertaken in both the primary and secondary phases of education. Within the USA educational system context; work has been undertaken within the K12 phase of education. Discussion and presentation of work and findings considers how different identified groups of learners can benefit from such technologies. Vignettes from expert classroom practitioners will highlight some of the issues and limitations which an end user needs to consider in seeking to apply the same approach in their own context. As this applies to the process, skills and methodology of technological application it is clear that the age phases to which this work is applicable are limitless. The poster will conclude with practical next steps for those seeking to implement such technology to enhance learning in their own work. This is presented in such a way as to be applicable to education professionals in all phases of education including primary, secondary, K12, undergraduate and even post graduate contexts.

description: By using the Schwinger-Keldysh approach, we evaluate the current noise and the charge noise of the single-electron transistor (SET) in the regime of large charge fluctuations caused by large tunneling conductance. Our result interpolates between previous theories; the "orthodox" theory and the "co-tunneling theory". We find that the life-time broadening effect suppresses the Fano factor below the value estimated by the previous theories. We also show that the large tunnel conductance does not reduce the energy sensitivity so much. Our results demonstrate quantitatively that SET electrometer can be used as the high-sensitivity and high-speed device for quantum measurements.

Next, we introduce the notion of weighted $(m,T)$-capacity in the complex Hessian setting and we investigate the link with the weighted $m$-extremal function. As an application we give a characterization of the Cegrell classes ${\mathscr F}^m$ and ${\mathscr E}^m$ by means of the weighted $(m,1)$-capacity. Furthermore, we prove a subsolution theorem for a general complex Hessian equation relatively to $T$.

description: With an energy scale that can be as high as $10^{14}\,{\rm GeV}$, inflation may provide a unique probe of high-energy physics. Both scalar and tensor fluctuations generated during this early accelerated expansion contain crucial information about the particle content of the primordial universe. The advent of ground- and space-based interferometers enables us to probe primordial physics at length-scales much smaller than those corresponding to current CMB constraints. One key prediction of single-field slow-roll inflation is a red-tilted gravitational wave spectrum, currently inaccessible at interferometer scales. Interferometers probe directly inflationary physics that deviates from the minimal scenario and in particular additional particle content with sizeable couplings to the inflaton field. We adopt here an effective description for such fields and focus on the case of extra spin-2 fields. We find that a time-dependent sound speed for the helicity-2 modes can generate primordial gravitational waves with a blue-tilted spectrum, potentially detectable at interferometer scales.

Variations in Enabling Educators' academic identities: A phenomenographic study of Enabling Educators' experiences in pathway programs

description: Enabling Educators are important stakeholders in widening university participation. However, little is known about these academics, a knowledge gap that contributes to their marginalisation and lack of recognition in higher education. This thesis uses a phenomenographic study of variations in Enabling Educators’ academic identities to explore their experiences and understandings of working in pathway programs. Data was collected via 31 open-ended questionnaires and 14 semi-structured interviews with Enabling Educators across the sector. Data analysis generated five qualitatively distinct variations in Enabling Educator Identity (EEI): equity advocate, student academic developer, empowerer, carer and educator. Individually, each variation in EEI represents a critical higher education strategy that Enabling Educators contribute to pathway programs. Collectively, the five variations in EEI represent a comprehensive, holistic response to widening university participation. The study further generated a description of Enabling Educators as pathway academics who are student-focused educators teaching non-traditional students essential academic capabilities to improve equity in university participation. The study made several recommendations regarding the identities and work of Enabling Educators. Firstly, Enabling Educators be afforded greater recognition and validation as academics. Secondly, Enabling Educators’ workloads require adjustment to reflect the time intensity and emotional burden of working in pathway programs. Thirdly, greater support be afforded to developing research and a research agenda in enabling education that explores enabling pedagogies and curriculum. Finally, that the funding, recognition and support of pathway programs be prioritised and continued.

description: White lupin (Lupinus albus) is a good source of protein for animal feed and stands out as an alternative to soybean in the local market. How­ever, the cultivation of the crop has declined in Greece mostly due to farmers opting for more profitable crops with better yields. The warm and dry climate in Greece leads to a drought impacting on lupin cultivation. This is the main agronomic risk. Precision irrigation combined with the good adaptation of domestic cultivars to local conditions can increase yields, thus revitalising lupin production. We conducted an experiment using a precision irrigation system to achieve the optimum yield and identify the irrigation needs based on field trial.

We perform measurements of X-ray diffraction, dc magnetization, ESR, and electrical resistivity. These samples show at $T_C$ a paramagnetic (PM) to ferromagnetic (FM) transition, however, we found that for $n>0.50$ there is a coexistence of both of these phases below $T_C$. On lowering $T$ below the charge-ordering (CO) temperature $T_{CO}$ all the samples exhibit a coexistence between the FM metallic and CO (antiferromagnetic) phases. In the whole $T$ range the FM phase fraction ($X$) decreases with increasing $n$. Furthermore, we show that only for $n\leq 0.50$ the metallic fraction is above the critical percolation threshold $X_C\simeq 15.5%$. As a consequence, these samples show very different magnetoresistance properties. In addition, for $n\leq 0.50$ we observe a percolative metal-insulator transition at $T_{MI}$, and for $T_{MI}

description: This paper presents tunable voltage reference (TVR) designed in a standard general purpose 65nm CMOS technology. Designed circuit is based on two-transistor (2T) voltage reference (VR) with digitally controlled operational amplifier (OPAMP). Developed TVR provides stable output voltage from 0.38 V to 1.1 V with non-linear tuning step under 0.5% of the output voltage (from 1.9 mV to 2.9 mV). The supply voltage in the range from 0.91 V to 1.5 V is used. The circuit offers parameter PSRR = -53.59 dB (at 1 kHz) and line regulation (LNR) of 0.35% in the worst case. The required area is 0.0185 mm2 . The proposed TVR was used to precise frequency tuning of oscillator. Provided results are obtained from both simulations and measurement of the manufactured ASIC prototype.

description: In the case of some agricultural investments, often net cash flow changes its sign from positive to negative, many times during the project. It causes the problem of internal rate of return calculation, which is an important indicator of economic effectiveness of investments. That is, in such situations, internal rate of return cannot be used. To solve this problem, modified rate of return is applied. This paper aimed to describe this method in detail, and to show its calculation for investments in pigs fattening. By application of modified internal rate of return it is determined that pigs fattening, under assumed conditions, is economically justified. Also, authors calculated the upper limit of discount rate (cost of capital), to which investment in pigs fattening is economically justified. It is concluded that, in the case of specific agricultural investments (such as pigs fattening), the use of traditional internal rate of return could give the wrong image on actual rate of return on investments.

description: A Gallai coloring of a complete graph $K_n$ is an edge coloring without triangles colored with three different colors. A sequence $e_1\ge \dots \ge e_k$ of positive integers is an $(n,k)$-sequence if $\sum_{i=1}^k e_i=\binom{n}{2}$. An $(n,k)$-sequence is a G-sequence if there is a Gallai coloring of $K_n$ with $k$ colors such that there are $e_i$ edges of color $i$ for all $i,1\le i \le k$. Gyárfás, Pálvölgyi, Patkós and Wales proved that for any integer $k\ge 3$ there exists an integer $g(k)$ such that every $(n,k)$-sequence is a G-sequence if and only if $n\ge g(k)$. They showed that $g(3)=5, g(4)=8$ and $2k-2\le g(k)\le 8k^2+1$. We show that $g(5)=10$ and give almost matching lower and upper bounds for $g(k)$ by showing that with suitable constants $α,β>0$, $\frac{αk^{1.5}}{\ln k}\le g(k) \le βk^{1.5}$ for all sufficiently large $k$.

description: The paper presents the selected results of consumers’ study of food products in Serbia. It focuses on the products with nutrition and health claims (NHCs) and the analysis of the main consumers’ characteristics which influence their awareness and knowledge about NHCs, their attitudes toward products with NHC and their purchase intentions. Different socio-demographic factors that influence consumers’ behavior were investigated. Education, gender, age and income of the respondents are the key factors which influence awareness, knowledge and consumption. As those products are closely related to consumers’ health, we presented the results based on the differences in health status of the respondents. Main findings show that the respondents with health problems do not consume those products as often as others, which is the outcome of a low level of nutrition knowledge. This represents a major restraining factor for the increase in consumption. After identifying the characteristics of demand, we have suggested some proposals for managers, aimed at overcoming the identified problems, and for government institutions so as to obtain a proactive approach to improving the overall health of the population.

description: We investigate the ground state properties of one-dimensional hard-core bosons interacting via a variable long-range potential using the density matrix renormalization group. We demonstrate that restoring energy extensivity in the system, which is done by rescaling the interaction potential with a suitable size-dependent factor known as Kac's prescription, has a profound influence on the low-energy properties in the thermodynamic limit. While an insulating phase is found in the absence of Kac's rescaling, the latter leads to a new metallic phase that does not fall into the conventional Luttinger liquid paradigm. Our results in one dimension illustrate the subtlety of determining the thermodynamic properties of generic long-range quantum systems.

description: Off-diagonal geometric phases acquired in the evolution of a spin-1/2 system have been investigated by means of a polarized neutron interferometer. Final counts with and without polarization analysis enable us to observe simultaneously the off-diagonal and diagonal geometric phases in two detectors. We have quantitatively measured the off-diagonal geometric phase for noncyclic evolutions, confirming the theoretical predictions. We discuss the significance of our experiment in terms of geometric phases (both diagonal and off-diagonal) and in terms of the quantum erasing phenomenon.

description: According to the standard imitation protocol, a less successful player adopts the strategy of the more successful one faithfully for future success. This is the cornerstone of evolutionary game theory that explores the vitality of competing strategies in different social dilemma situations. In our present work we explore the possible consequences of two slightly modified imitation protocols that are exaggerated and gradual learning rules. In the former case a learner does not only adopt, but also enlarges the strategy change for the hope of a higher income. Similarly, in the latter case a cautious learner does not adopt the alternative behavior precisely, but takes only a smaller step towards the other's strategy during the updating process. Evidently, both scenarios assume that the players' propensity to cooperate may vary gradually between zero (always defect) and one (always cooperate) where these extreme states represent the traditional two-strategy social dilemma. We have observed that while the usage of exaggerated learning has no particular consequence on the final state, but gradual learning can support cooperation significantly. The latter protocol mitigates the invasion speeds of both main strategies, but the decline of successful defector invasion is more significant, hence the biased impact of the modified microscopic rule on invasion processes explains our observations.

Direct baryogenesis in the broken phase

description: We show a new mechanism for baryogenesis where the reheating temperature can be smaller than the electroweak scale. The baryon number symmetry is violated by a dimension nine operator which conserves a baryon parity. A high energy quark from the decay of a heavy particle, $e.g.$ inflaton, modulus or gravitino, undergoes flavor oscillation, and is thermalized due to the scatterings with the ambient thermal plasma. We point out that the baryon asymmetry of our universe can be generated due to the scatterings via the baryon number violating operator. Our scenario can be tested in neutron-antineutron oscillation experiments as well as other terrestrial experiments.

description: In this article, I discuss measures of effect size for two-group comparisons where data are not appropriately analyzed by least-squares methods. The Mann–Whitney test calculates a statistic that is a very useful measure of effect size, particularly suited to situations in which differences are measured on scales that either are ordinal or use arbitrary scale units. Both the difference in medians and the median difference between groups are also useful measures of effect size.

description: We propose an effective description of 0-brane black holes, in which the black hole is modeled as a gas of non-interacting quasi-particles in the dual quantum mechanics. This simple model is shown to account for many of the static thermodynamic properties of the black hole. It also accounts for dynamical properties, such as the rate at which energy gets thermalized by the black hole. We use the model to show that the entropy of the quantum mechanics is proportional to the black hole horizon area in Planck units.

description: Almost all of the entropy in the universe is in the form of Bekenstein--Hawking (BH) entropy of super-massive black holes. This entropy, if it satisfies Boltzmann's equation $S=\log{\cal N}$, hence represents almost all the accessible phase space of the Universe, somehow associated to objects which themselves fill out a very small fraction of ordinary three-dimensional space. Although time scales are very long, it is believed that black holes will eventually evaporate by emitting Hawking radiation, which is thermal when counted mode by mode. A pure quantum state collapsing to a black hole will hence eventually re-emerge as a state with strictly positive entropy, which constitutes the famous black hole information paradox. Expanding on a remark by Hawking we posit that BH entropy is a thermodynamic entropy, which must be distinguished from information-theoretic entropy. The paradox can then be explained by information return in Hawking radiation. The novel perspective advanced here is that if BH entropy counts the number of accessible physical states in a quantum black hole, then the paradox can be seen as an instance of the fundamental problem of statistical mechanics. We suggest a specific analogy to the increase of the entropy in a solvation process. We further show that the huge phase volume (${\cal N}$), which must be made available to the universe in a gravitational collapse, cannot originate from the entanglement between ordinary matter and/or radiation inside and outside the black hole. We argue that, instead, the quantum degrees of freedom of the gravitational field must get activated near the singularity, resulting in a final state of the `entangled entanglement' form involving both matter and gravity.
