description: To potentially reduce bias in hypothetical choice experiments, many studies have incentivized respondents to reveal more truthful choices by randomly choosing a binding choice set and then asking them to pay the price indicated for the chosen product alternative in this binding choice set. This approach, however, does not separate the price the respondent indicated he/she is willing to pay for the chosen product alternative from the price that he/she will end up paying. Would the use of the Becker-DeGroot-Marshack (BDM) mechanism make non-hypothetical choice experiments more demand revealing? Our results using a conventional homegrown choice experiment and an induced value choice experiment suggest that it does not. Choice behavior is associated with the degree of understanding about the experimental procedures and the amount of time devoted to examine the choice set.

description: Magnetic reconnection may be the fundamental process allowing energy stored in magnetic fields to be released abruptly, solar flares and coronal mass ejection (CME) being archetypal natural plasma examples. Magnetic reconnection is much too slow a process to be efficient on the large scales, but accelerates once small enough scales are formed in the system. For this reason, the fractal reconnection scenario was introduced (Shibata and Tanuma 2001) to explain explosive events in the solar atmosphere: it was based on the recursive triggering and collapse via tearing instability of a current sheet originally thinned during the rise of a filament in the solar corona. Here we compare the different fractal reconnection scenarios that have been proposed, and derive generalized scaling relations for the recursive triggering of fast, `ideal' - i.e. Lundquist number independent - tearing in collapsing current sheet configurations with arbitrary current profile shapes. An important result is that the Sweet-Parker scaling with Lundquist number, if interpreted as the aspect ratio of the singular layer in an ideally unstable sheet, is universal and does not depend on the details of the current profile in the sheet. Such a scaling however must not be interpreted in terms of stationary reconnection, rather it defines a step in the accelerating sequence of events of the ideal tearing mediated fractal cascade. We calculate scalings for the expected number of plasmoids for such generic profiles and realistic Lundquist numbers.

description: Accumulating evidence suggests that many respondents in stated choice experiments use simplifying strategies and heuristics. Such behavior is a deviation from random utility theory and can lead to biased estimates if not appropriately considered. This paper is a first attempt to systematically explore the use of the satisficing heuristic (Simon, 1955) in the context of a stated choice experiment. We consider 944 possible satisficing rules and allow respondents to revise the rules adopted throughout the choice sequence. While only a small proportion of respondents used the same satisficing rule across the entire sequence, allowing for changes in behavior at different stages reveals evidence that the use of the heuristic follows a learning and fatigue path. Furthermore, considering respondents satisficing leads to improved model fits and different marginal willingness-to-pay estimates.

description: I study the relationship between demand similarity and foreign direct investment in the food and beverage industry. My regression specification includes a measure of similarity in income per capita to proxy for similarity in demand. Using firm-level greenfield investment data, I find a significant effect of income similarity along the intensive and extensive margin of foreign direct investment. My findings show that investment activities are more intense between countries with similar income per capita. The similarity effect is larger for the intensive margin, implying that it is not only more likely that an investment is realized between countries with similar income per capita, but also that such a project involves a considerable larger investment and creates more jobs. Although I find evidence for heterogeneity in the similarity effect, all coefficient estimates have a negative sign. Moreover, distinguishing between types of foreign direct investment, I find that the similarity effect is mainly relevant for manufacturing projects. These results show that demand for quality is an important determinant of cross-border investment activities in the food and beverage industry.

description: In recent times, there has been an explosive growth in wireless communications. With a rapid advance in wireless communication systems and an increasing importance of other wireless applications, antennas which are designed to address more than one band/service at time are in great demand in both commercial as well as military sectors. This booming demand has resulted in a renewed interest in multiband antennas. In this project a study of existing popular techniques for generating multiple bands of resonance and corresponding multiband antenna designs has been presented. Furthermore, a novel and compact dual band planar antenna for 2.4/5.2/5.8-GHz wireless local area network (WLAN), 2.3/3.5/5.5GHz Worldwide Inter-operability for Microwave Access (WiMAX) and Bluetooth applications is proposed and studied in this report. The antenna comprises of an L-shaped radiating element which is coupled with a ground shorted parasitic resonator to generate three resonant modes for tri-band operation. The L-shaped element which is placed on top of the substrate is fed by a 50 ohm microstrip feed line and is responsible for the generation of a wide band at 5.5 GHz. The parasitic resonator is placed on the other side of the substrate and is directly connected to the ground plane. The presence of the parasitic resonator gives rise to two additional resonant bands at 2.3 GHz and 3.5 GHz. Thus, together the two elements generate three resonant bands to cover WLAN, WiMAX and Bluetooth bands of operation while occupying a small area of around 15.9 mm x 7.4 mm. Important antenna parameters such as return loss, radiation pattern, peak gains and radiation effciencies in the operating bands have been studied in detail. Finally, the antenna has been compared with some recently proposed designs with respect to performance and other features to prove that the proposed design is a promising candidate for the aforementioned wireless technologies.

description: Millennials, those born between 1980 and 2000, have captured the attention of researchers, media, and the food industry alike, as their tastes and preferences are increasingly shaping what is being purchased at the grocery store. Market analysis has shown that this generation is demanding healthier and fresher items and spending fewer of their food expenditures at restaurants. However, to our knowledge, no research has specifically examined how millennials’ purchasing decisions differ after controlling for a robust set of demographic and socioeconomic (SES) variables. The goal of our research is to investigate whether the purchasing decisions of millennial households differ significantly from the rest of the population, looking both at the healthfulness of food purchases as well as the shopping environment used to purchase food-at-home. Overall, our study finds that being a millennial had a small and positive effect on diet quality when we measure diet quality as the deviation from the Dietary Guidelines for Americans. However, once we correct for overconsumption of healthy foods and underconsumption of unhealthy foods, this difference disappears suggesting that millennials are better at complying to the recommended guidelines.

description: Many problems in physics, material sciences, chemistry and biology can be abstractly formulated as a system that navigates over a complex energy landscape of high or infinite dimensions. Well-known examples include phase transitions of condensed matter, conformational changes of biopolymers, and chemical reactions. The energy landscape typically exhibits multiscale features, giving rise to the multiscale nature of the dynamics. This is one of the main challenges that we face in computational science. In this report, we will review the recent work done by scientists from several disciplines on probing such energy landscapes. Of particular interest is the analysis and computation of transition pathways and transition rates between metastable states. We will then present the string method that has proven to be very effective for some truly complex systems in material science and chemistry.

description: Disease psoriasis occurs as chronic inflammation of skin and appears as scaly red lesions on skin surface. Advent of several immunosuppressive drugs established that the disease stems from immuno-pathogenic disorder in human blood. Cell biological as well as clinical research on the disease reveals that the helper T-cells and other Leucocytes, responsible for human immunity, may lead to psoriasis pathogenesis if produced in plenty at locations close to the dermal region. Research findings also showed that a complex, self-sustaining (cytokine and related) proteins network play important role in disease maturation by actually leading to a huge proliferation of epidermal keratinocytes. Disease pathogenesis is identified with such hyperproliferation leading to flaking of skin surface (psoriatic plaques). An excessive generation of nitric oxide by proliferated keratinocytes, through a complex chain of bio-chemical events, is causal to the scaliness of psoriatic plaques. Considering these immunopathogenic mechanisms, we propose and analyse a mathematical time differential model for the disease psoriasis. Outcomes of analysis are consistent with existing cell biological and clinical findings with some new predictions which could be tested further.

Essa è quindi una data importantissima per la città, che però pare passare inosservata. Se non fosse stato per la lungimiranza di Emanuele Filiberto di Savoia, che scelse la città come nuova capitale del Ducato al posto di Chambéry, Torino non avrebbe fato l'Italia. La data del 7 Febbraio1563 è anche la data scelta da Giuditta Dembech come data convenzionale per la nascita di Torino. In un suo libro, si parte dalla città romana, di cui si sottolinea l'orientamento solare del decumano. Non avendo la data di fondazione romana, la scrittrice ha appunto scelto l'ingresso ufficiale di Emanuele Filiberto in Torino. Ora si discute quanto compare nel libro di Dembech, rispetto a quanto in passato propose nel 1869 lo storico tedesco Heinrich Nissen sulla direzione dei decumani.
description: Di recente ho individuato due scritti di Heinrich Nissen che parlano di Torino. Uno è un accenno all'orientazione di Torino col sorgere del sole al solstizio d'inverno, l'altro è specifico sulla Torino Romana, con riferimento al libro di Carlo Promis, Storia dell'antica Torino: Julia Augusta Taurinorum, 1869.

description: The tumor suppressor p53 regulates different cellular pathways involved in cell survival, DNA repair, apoptosis, and senescence. However, according to an increasing number of studies, the p53-mediated canonical DNA damage response is dispensable for tumor suppression. p53 is involved in mechanisms regulating many other cellular processes, including metabolism, autophagy, and cell migration and invasion, and these pathways might crucially contribute to its tumor suppressor function. In this review we summarize the canonical and non-canonical functions of p53 in an attempt to provide an overview of the potentially crucial aspects related to its tumor suppressor activity.

All these fields are defined on a curved spacetime of arbitrary (odd) dimensions. A new form of gauge transformations is introduced and plays an essential role in defining the interaction with a magnetic monopole or in defining the generalized Chern-Simons terms.

description: The quantum dynamics of the symmetry broken lambda (Phi^2)^2 scalar field theory in the presence of an homogeneous external field is investigated in the large N limit. We choose as initial state the ground state for a constant external field J .The sign of the external field is suddenly flipped from J to - J at a given time and the subsequent quantum dynamics calculated. Spinodal instabilities and parametric resonances produce large quantum fluctuations in the field components transverse to the external field. This allows the order parameter to turn around the maximum of the potential for intermediate times. Subsequently, the order parameter starts to oscillate near the global minimum for external field - J, entering a novel quasi-periodic regime.

description: Several studies have examined the causes and consequences of major national security problems, especially terrorism, which has become a major challenge across the globe. Other studies have examined terrorists target behavior. While food security is widely accepted as an important element of national security, few studies, if any, have explored the nexus between both. By focusing on terrorism and using the Boko Haram insurgency in Nigeria as a case study, this paper explores three dimensions of the food-national security nexus. First, it presents a conceptual framework to explain food security as a root cause of terrorism. Second, it presents a conceptual and a theoretical framework for explaining why and how terrorists target agriculture and food security and presents empirical evidence to support a number of related hypotheses. Third, it presents yet another conceptual framework for explaining the consequences of terrorism and explores several effects on agriculture and food security. The paper concludes by presenting important reasons why the nexus between food security and national security should be more aptly investigated and discusses the benefits of such investigation.

description: Co-infection of plant hosts by two or more viruses is common in agricultural crops and natural plant communities. A variety of models have been used to investigate the dynamics of co-infection which track only the disease status of infected and co-infected plants, and which do not explicitly track the density of inoculative vectors. Much less attention has been paid to the role of vector transmission in co-infection, that is, acquisition and inoculation and their synergistic and antagonistic interactions. In this investigation, a general epidemiological model is formulated for one vector species and one plant species with potential co-infection in the host plant by two viruses. The basic reproduction number provides conditions for successful invasion of a single virus. We derive a new invasion threshold which provides conditions for successful invasion of a second virus. These two thresholds highlight some key epidemiological parameters important in vector transmission. To illustrate the flexibility of our model, we examine numerically two special cases of viral invasion. In the first case, one virus species depends on an autonomous virus for its successful transmission and in the second case, both viruses are unable to invade alone but can co-infect the host plant when prevalence is high.

description: Sugar-sweetened beverage (SSB) consumption is independently associated with several non-communicable diseases, so policymakers are increasingly implementing measures, such as marketing regulation, to reduce intake. To help understand how such measures work, this study examined the association between SSB consumption and self-reported exposure to SSB promotions, both overall and by type of promotion, and whether these relationships vary between the UK, USA, Canada, Mexico, and Australia. Cross-sectional analysis of the online 2017 International Food Policy Study was performed (n = 15,515). Participants were grouped into 5265 (34%) non-, 5117 (33%) low-, and 5133 (33%) high-SSB consumers. Multinomial logistic regression models examined whether SSB consumption varied by exposure to total SSB promotion and by type: traditional, digital, recreational environment, and functional environment. Multiplicative interactions were included to investigate international variations. An additional unit of total self-reported SSB promotion exposure increased the likelihood of participants being low SSB consumers (relative risk ratio (RRR) = 1.08, 95% confidence interval (CI) = 1.06−1.10) and high SSB consumers (RRR = 1.13, 95% CI = 1.11−1.16). Only exposure to traditional and digital promotion increased the likelihood of participants being SSB consumers, though this may be explained by degree of exposure, which was not measured in this study. Some evidence illustrated international variation in these relationships.

description: Dynamic channel selection is among the most important wireless communication elements in dynamically changing electromagnetic environments wherein a user can experience improved communication quality by choosing a better channel. Multi-armed bandit (MAB) algorithms are a promising approach by which the difficult tradeoff between exploration to search for better a channel and exploitation to experience enhanced communication quality is resolved. Ultrafast solution of MAB problems has been demonstrated by utilizing chaotically oscillating time series generated by semiconductor lasers. In this study, we experimentally demonstrate a MAB algorithm incorporating laser chaos time series in a wireless local area network (WLAN). Autonomous and adaptive dynamic channel selection is successfully demonstrated in an IEEE802.11a-based, four-channel WLAN. Although the laser chaos time series is arranged prior to the WLAN experiments, the results confirm the usefulness of ultrafast chaotic sequences for real wireless applications. In addition, we numerically examine the underlining adaptation mechanism of the significantly simplified MAB algorithm implemented in the present study compared with the previously reported chaos-based decision makers. This study provides a first step toward the application of ultrafast chaotic lasers for future high-performance wireless communication networks.

description: No spin-singlet $b \bar b$ quarkonium state has yet been observed. In this paper we discuss the production of the singlet P-wave $b\bar{b}$ and $c\bar{c}$ $^1P_1$ states $h_b$ and $h_c$. We consider two possibilities. In the first the $^1P_1$ states are produced via the electromagnetic cascades $\ups(3S) \to η_b(2S) + γ\to h_b + γγ\to η_b +γγγ$ and $ψ'\to η_c' + γ\to h_c + γγ\to η_c + γγγ$. A more promising process consists of single pion transition to the $^1P_1$ state followed by the radiative transition to the $1^1S_0$ state: $\ups(3S)\to h_b + π^0 \to η_b + π^0 +γ$ and $ψ' \to h_c + π^0 \to η_c + π^0 +γ$. For a million $\ups(3S)$ or $ψ'$'s produced we expect these processes to produce several hundred events.

description: By using the momentum-space Lanczos recursive method which considers rigorously all multiple-scattering events, we unveil that the non-perturbative disorder effect has dramatic impact on the charge transport of a two-dimensional electron system with Rashba spin-orbit coupling in the low-density region. Our simulations find a power-law dependence of the dc longitudinal conductivity on the carrier density, with the exponent linearly dependent on the Rashba spin-orbit strength but independent of the disorder strength. Therefore, the classical charge transport influenced by complicated multiple-scattering processes also shows the characteristic feature of the spin-orbit coupling. This highly unconventional behavior is argued to be observable in systems with tunable carrier density and Rashba splitting, such as the LaAlO$_{3}$/SrTiO$_{3}$ interface, the heterostructure of Rashba semiconductors bismuth tellurohalides and the surface alloy Bi$_x$Pb$_y$Sb$_{1-x-y}$/Ag(111).

description: Abstract: Acoustic emission (AE) measurements of avalanches in different systems, such as domain movements in ferroics or the collapse of voids in porous materials, cannot be compared with model predictions without a detailed analysis of the AE process. In particular, most AE experiments scale the avalanche energy E, maximum amplitude Amax and duration D as E ~ Amaxx and Amax ~ Dχ with x = 2 and a poorly defined power law distribution for the duration. In contrast, simple mean field theory (MFT) predicts that x = 3 and χ = 2. The disagreement is due to details of the AE measurements: the initial acoustic strain signal of an avalanche is modified by the propagation of the acoustic wave, which is then measured by the detector. We demonstrate, by simple model simulations, that typical avalanches follow the observed AE results with x = 2 and ‘half-moon’ shapes for the cross-correlation. Furthermore, the size S of an avalanche does not always scale as the square of the maximum AE avalanche amplitude Amax as predicted by MFT but scales linearly S ~ Amax. We propose that the AE rise time reflects the atomistic avalanche time profile better than the duration of the AE signal.

description: In SSA, if maize moisture content cannot be detected, traders and consumers have no incentive to dry maize to ≤ 13.0 percent moisture, resulting in fungal growth and aflatoxin contamination. Using an experimental auction in SSA, we elicit trader and consumer WTP for maize labeled with varying moisture contents. Participants revealed a preference for drier maize when they knew the moisture content, but could not distinguish between unlabeled maize dried to ≤ 13.0 percent moisture and 14-15.9 percent moisture.

Plus (2018) 133 : 530) for the Klein-Gordon equation with the Aharonov-Bohm and Coulomb potentials in a Gödel-type space-time. We derive the final form of the radial wave equation of the Klein-Gordon equation in the Som-Raychaudhuri space-time with these potentials and show that the derive equation here jeopardize the equations obtained in Ref. [1] and therefore, the energy eigenvalues presented there is incorrect.

description: Abstract: We measured the sustained neural response to electrical stimulation by a cochlear implant (CI). To do so, we interleaved two stimuli with frequencies F1 and F2 Hz and recorded a neural distortion response (NDR) at F2-F1 Hz. We show that, because any one time point contains only the F1 or F2 stimulus, the instantaneous nonlinearities typical of electrical artefact should not produce distortion at this frequency. However, if the stimulus is smoothed, such as by charge integration at the nerve membrane, subsequent (neural) nonlinearities can produce a component at F2-F1 Hz. We stimulated a single CI electrode with interleaved sinusoids or interleaved amplitude-modulated pulse trains such that F2 = 1.5F1, and found no evidence for an NDR when F2-F1 was between 90 and 120 Hz. However, interleaved amplitude-modulated pulse trains with F2-F1~40 Hz revealed a substantial NDR with a group delay of about 45 ms, consistent with a thalamic and/or cortical response. The NDR could be measured even from recording electrodes adjacent to the implant and at the highest pulse rates (> 4000 pps) used clinically. We then measured the selectivity of this sustained response by presenting F1 and F2 to different electrodes and at different between-electrode distances. This revealed a broad tuning that, we argue, reflects the overlap between the excitation elicited by the two electrodes. Our results also provide a glimpse of the neural nonlinearity in the auditory system, unaffected by the biomechanical cochlear nonlinearities that accompany acoustic stimulation. Several potential clinical applications of our findings are discussed.

description: The objective of this research is to analyze the current status and process of Vietnam's rural development to draw lessons for improving the quality of rural life and achieving sustainable rural development in Vietnam. The research was carried out by the following methods. First, the paper reviews previous studies on concepts and theoretical perspectives on rural development and comes up with a concrete definition of the term ‘rural development’ for this research to build a Rural Development Index (RDI). Second, the RDI is developed as a tool to evaluate the current status and process of rural development. Third, the paper examines the current status and development process of Vietnam's rural development using the RDI. The scope of this study covered 63 regions (58 provinces and 5 municipalities) in Vietnam. This research can be used to establish mid- and long-term visions and strategies of rural development policies in Vietnam.

description: We study the growth of entanglement in quantum systems with a conserved quantity exhibiting diffusive transport, focusing on how initial inhomogeneities are imprinted on the entropy. We propose a simple effective model, which generalizes the minimal cut picture of \textit{Jonay et al.} in such a way that the `line tension' of the cut depends on the local entropy density. In the case of noisy dynamics, this is described by a Kardar-Parisi-Zhang (KPZ) equation coupled to a diffusing field. We investigate the resulting dynamics and find that initial inhomogeneities of the conserved charge give rise to features in the entanglement profile, whose width and height both grow in time as $\propto\sqrt{t}$. In particular, for a domain wall quench, diffusion restricts entanglement growth to be $S_\text{vN} \lesssim \sqrt{t}$. We find that for charge density wave initial states, these features in the entanglement profile are present even after the charge density has equilibrated. Our conclusions are supported by numerical results on random circuits and deterministic spin chains.

description: Temperature-independent magnetic viscosity in ferritin has been observed from 2 K down to 100 mK, proving that quantum tunneling plays the main role in these particles at low temperature. Magnetic relaxation has also been studied using the Landau-Zener method making the system crossing zero resonant field at different rates, alpha=dH/dt, ranging from 10^{-5} to 10^{-3} T/s, and at different temperatures, from 150 mK up to the blocking temperature. We propose a new Tln(Delta H_{eff}/tau_0 alpha) scaling law for the Landau-Zener probability in a system distributed in volumes, where Delta H_{eff} is the effective width of the zero field resonance.

description: Typically, polyurea is a polymer forming microphase-separated structures. Various coarse-grained (CG) simulation models have been developed to study the microphase structure and viscoelastic properties of polyurea. However, since the hydrogen atoms were modelled implicitly in the existing CG models, the anisotropic hydrogen bonding between urea groups in the hard domain might not be treated properly. Here, we introduce a hybrid all-atom/coarse-grained (AA/CG) model for polyurea, the CGU model, in which atomistic resolution are preserved for the urea groups. This model is proven to reproduce the results of the AA model, despite 24 times faster to run. By comparing the traditional CG model and the CGU model, we found that hydrogen bonding leads to a head-to-tail arrangement of the urea groups and a significant slowdown of the hard segment dynamics. Non-equilibrium simulations of stress relaxation process indicate that hydrogen bonding causes a broad relaxation time spectrum, which is consistent with experiment results.
