description: Analytical and geometrical properties of generalized power-law (GPL) density profiles are investigated in detail. In particular, a one-to-one correspondence is found between mathematical parameters and geometrical parameters. Then GPL density profiles are compared with simulated dark haloes (SDH) density profiles, and nonlinear least-absolute values and least-squares fits involving the above mentioned five parameters (RFSM5 method) are prescribed. More specifically, the sum of absolute values or squares of absolute logarithmic residuals is evaluated on a large number of points making a 5-dimension hypergrid, through a few iterations. The size is progressively reduced around a fiducial minimum, and superpositions on nodes of earlier hypergrids are avoided. An application is made to a sample of 17 SDHs on the scale of cluster of galaxies, within a flat $Λ$CDM cosmological model (Rasia et al. 2004). In dealing with the mean SDH density profile, a virial radius, averaged over the whole sample, is assigned, which allows the calculation of the remaining parameters. Using a RFSM5 method provides a better fit with respect to other methods. No evident correlation is found between SDH dynamical state (relaxed or merging) and asymptotic inner slope of the logarithmic density profile or (for SDH comparable virial masses) scaled radius. Mean values and standard deviations of some parameters are calculated, and a comparison with previous results is made with regard to the scaled radius. A certain degree of degeneracy is found in fitting GPL to SDH density profiles. If it is intrinsic to the RFSM5 method or it could be reduced by the next generation of high-resolution simulations, still remains an open question.

description: Universality is one of the key concepts in understanding critical phenomena. However, for interacting inhomogeneous systems described by complex networks a clear understanding of the relevant parameters for universality is still missing. Here we discuss the role of a fundamental network parameter for universality, the spectral dimension. For this purpose, we construct a complex network model where the probability of a bond between two nodes is proportional to a power law of the nodes' distances. By explicit computation we prove that the spectral dimension for this model can be tuned continuously from $1$ to infinity, and we discuss related network connectivity measures. We propose our model as a tool to probe universal behaviour on inhomogeneous structures and comment on the possibility that the universal behaviour of correlated models on such networks mimics the one of continuous field theories in fractional Euclidean dimensions.

description: This study aims to analyze the attributes considered in choosing rural sites for tourism purposes by city dwellers and the market segmentation of rural tourism from a rural tourism demand perspective. For this purpose, this study investigates the attributes of rural areas considered in the selection of rural tourism destinations by urban dwellers using a conjoint model as a stated preference model. Based on literature reviews, two questionnaire surveys are conducted. The first questionnaire survey is performed in the 4 cities of Seoul, Daejeon, Suwon and Chuncheon with 408 urban residents. The second questionnaire survey is performed in the 5 cities of Seoul, Chuncheon, Daejeon, Cheonju and Busan with about 1,060 urban residents. The study results suggest that according to part-worth and vector models, the most important attributes in selecting rural areas for tourism are experience programs and facility convenience. The fitness level of the model ranges from 0.917 to 0.986, which is very significant. Among the 5 attribute's levels, the rural residents' obliging service, the traditional and the ecological programs and the facilities about information and accommodation are more critical factors than other levels. Utilities of each level decrease as cost and arrival time increase. Regarding the result of market segmentation, respondents having intention to visit can be divided into 4 groups; (1) facility/program-oriented group, (2) service-oriented group, (3) time-oriented group, and (4) simple participants group. These results can provide insightful information for regional planning strategies, such as selection of market segment type and the key factor of facility and space planning.

description: Density functional calculations with a large unit cell have been conducted to investigate adsorption, segregation and magnetization of Mn monomer on GaAs(110). The Mn adatom is rather mobile along the trench on GaAs(110), with an energy barrier of 0.56 eV. The energy barrier for segregation across the trenches is nevertheless very high, 1.67 eV. The plots of density of states display a wide gap in the majority spin channel, but show plenty of metal-induced gap states in the minority spin channel. The Mn atoms might be invisibl in scanning tunneling microscope (STM) images taken with small biases, due to the directional p-d hybridization. For example, one will more likely see two bright spots on Mn/GaAs(110), despite the fact that there is only one Mn adatom in the system.

description: In this work we show the existence of supersymmetry and degeneracy for an arbitrary number of Majorana fermions (even or odd) without to invoke any symmetry of Hamiltonian. Next, we analyze the supersymmetry at finite temperature using the thermofield dynamics formalism. Furthermore we derive thermal braiding operators through the Bogoliubov transformations and we find its action on a thermal Bell state.

description: This work proposes and analyzes the use of keystroke biometrics for content de-anonymization. Fake news have become a powerful tool to manipulate public opinion, especially during major events. In particular, the massive spread of fake news during the COVID-19 pandemic has forced governments and companies to fight against missinformation. In this context, the ability to link multiple accounts or profiles that spread such malicious content on the Internet while hiding in anonymity would enable proactive identification and blacklisting. Behavioral biometrics can be powerful tools in this fight. In this work, we have analyzed how the latest advances in keystroke biometric recognition can help to link behavioral typing patterns in experiments involving 100,000 users and more than 1 million typed sequences. Our proposed system is based on Recurrent Neural Networks adapted to the context of content de-anonymization. Assuming the challenge to link the typed content of a target user in a pool of candidate profiles, our results show that keystroke recognition can be used to reduce the list of candidate profiles by more than 90%. In addition, when keystroke is combined with auxiliary data (such as location), our system achieves a Rank-1 identification performance equal to 52.6% and 10.9% for a background candidate list composed of 1K and 100K profiles, respectively.

Infant attention to phonetic detail in word forms : knowledge and familiarity effects
Creators: name: Fennell, Christopher Terrence
Publisher: name: University of British Columbia
Year: 2009

description: Several recent studies have shown that 14-month-old infants have difficulty learning to associate two phonetically similar new words to two different objects in the Switch task. Because infants can discriminate the same phonetic detail that they fail to use in word-learning situations, the argument is that this word-learning failure results from a processing overload on cognitive resources (resource limitation). However, an alternate explanation is that novice word learners fail in word-learning tasks because they have yet to build phonemic representations and rely on simpler phonetic representations in discrimination tasks (representational discontinuity). In Experiment One, these explanations were tested by exploring how infants perform in the Switch task with known minimally different words, which should ease processing since the object-label link is already established. Novice word learners succeeded in noticing the phonetic detail in these well-known words. These results are compatible with the limited resource explanation and discount the representational discontinuity argument by demonstrating that the relevant contrast is already present in words. Experiment Two further explored the resource limitation hypothesis by asking i f familiarity with a word-object combination is enough to ease processing and allow access to phonetic detail in the word. Fourteen-month-old infants succeeded in noticing the phonetic detail both when the word-object combination was well-known and when it was familiar. Experiment Three (Part A) confirmed that the infants' success in Experiment Two was not due to the perceptual salience of the contrast or to the use of the one-object version of the Switch procedure. Experiment Three (Part B) again explored the resource limitation theory by investigating if familiarity with the object alone, without familiarity with the word form, is enough to ease processing such that novice word learners could access phonetic detail. The standard analysis of total looking time did not reveal success in the task; however, an analysis of first looks indicated that the infants may be able to access phonetic detail when only the object is familiar. The studies presented in this thesis support continuity in the representation and differential access to phonetic detail as a function of processing load.

description: Growth of GaMnAs by molecular beam epitaxy is typically performed at low substrate temperatures (250C) and high As overpressures leading to the incorporation of excess As and Mn interstitials, which quench optical signals such as photoluminescence (PL). We report on optical-quality Ga(1-x)Mn(x)As/Al(0.4)Ga(0.6)As quantum wells (QWs) with x < 0.2% grown at a substrate temperature of 400C. Electrical and structural measurements demonstrate that this elevated temperature reduces As defects while allowing the substitutional incorporation of Mn into Ga sites. From a combination of Hall and secondary ion mass spectroscopy measurements we estimate that at least 70-90% of the Mn incorporates substitutionally in all samples studied. The incorporation behavior shows both a substrate temperature and QW width dependence. The lower defect density of these heterostructures, compared to typical lower temperature grown GaMnAs, enables the observation of both polarization-resolved PL and coherent electron spin dynamics, from which the conduction band exchange parameter is extracted. No evidence of long-range Mn spin coupling is observed, whereas negative effective Curie temperatures indicate spin heating due to photoexcitation. The electron spin lifetime is maximized for light Mn doping and shows little magnetic field dependence indicating that the Dyakonov-Perel mechanism is dominant in these structures. PL spectra reveal a low energy peak from shallow donors, which because of the paramagnetic behavior of its PL polarization, we ascribe to Mn interstitials.

description: The aim of this study was developing a scale with which to measure farmers’ attitude towards complete ownership of farmland. The research started by identifying 50 different statements based on review of the empirical literature and information obtained from stakeholders and experts. Of these statements, 30 items were selected and ultimately only 12 consistent and reliable statements were retained for inclusion in a five point Likert type scale. The 12 statements’ scale was administered on 335 randomly selected sample farmers to measure their attitude towards complete ownership of farmland. The result shows that about 85% and 9% of the respondents were favoring and disfavoring complete ownership of farmland, respectively. Only 6% of the sample respondents were undecided in terms of their preference for the complete ownership of farmland. This detailed study together with strict follow-up of data collection from the sample respondents has been extremely useful in developing a relatively consistent tool to measure farmers’ attitude. Therefore, the 12- item five point Likert scale can be applicable in similar situations of Ethiopia in particular, and in developing countries in general.

description: We present our spectroscopic observations of the galaxy NGC 7468 performed at the 6-m Special Astrophysical Observatory telescope using the UAGS long-slit spectrograph, the multipupil fiber spectrograph MPFS, and the scanning Fabry-Perot interferometer (IFP). We found no significant deviations from the circular rotation of the galactic disk in the velocity field in the regions of brightness excess along the major axis of the galaxy (the putative polar ring). Thus, these features are either tidal structures or weakly developed spiral arms. However, we detected a gaseous disk at the center of the galaxy whose rotation plane is almost perpendicular to the plane of the galactic disk. The central collision of NGC 7468 with a gas-rich dwarf galaxy and their subsequent merging seem to be responsible for the formation of this disk.

description: Topology ultimately unveils the roots of the perfect quantization observed in complex systems. The 2D quantum Hall effect is the celebrated archetype. Remarkably, topology can manifest itself even in higher-dimensional spaces in which control parameters play the role of extra, synthetic dimensions. However, so far, a very limited number of implementations of higher-dimensional topological systems have been proposed, a notable example being the so-called 4D quantum Hall effect. Here we show that mesoscopic superconducting systems can implement higher-dimensional topology and represent a formidable platform to study a quantum system with a purely nontrivial second Chern number. We demonstrate that the integrated absorption intensity in designed microwave spectroscopy is quantized and the integer is directly related to the second Chern number. Finally, we show that these systems also admit a non-Abelian Berry phase. Hence, they also realize an enlightening paradigm of topological non-Abelian systems in higher dimensions.

description: This paper aims to determine the solidity of the notion of the "coffee paradox" using annual data from 1977 to 2007. In the confines of an export supply model, we analyze the effects of export coffee price on export volume. Price and profit equation are used to determine the effects of market power on export coffee price and measure changes in the retail and export price. We also estimate the elasticity of transmission and price asymmetry as a means of verifying the "coffee paradox." Ordinary Least Square (OLS), Instrumental Variables (IV), and simultaneous equation with Seemingly Unrelated Regressions (SUR) methods of econometric analysis are employed. Empirical results suggest that the world coffee market is characterized by "coffee paradox" due to different changes between retail and export prices of coffee, and that it is the existence of market power in importing countries that is the main contributor to the condition of price asymmetry.

description: In recent years, the Internet of Things (IoT) has grown to include the tracking of devices through the use of Indoor Positioning Systems (IPS) and Location Based Services (LBS). When designing an IPS, a popular approach involves using wireless networks to calculate the approximate location of the target from devices with predetermined positions. In many smart building applications, LBS are necessary for efficient workspaces to be developed. In this paper, we examine two memoryless positioning techniques, K-Nearest Neighbor (KNN), and Naive Bayes, and compare them with simple trilateration, in terms of accuracy, precision, and complexity. We present a comprehensive analysis between the techniques through the use of three popular IoT wireless technologies: Zigbee, Bluetooth Low Energy (BLE), and WiFi (2.4 GHz band), along with three experimental scenarios to verify results across multiple environments. According to experimental results, KNN is the most accurate localization technique as well as the most precise. The RSSI dataset of all the experiments is available online.

description: This paper conducts several analyses to discuss about consumers' preference of rice brands and suggest a way to reduce the number that currently stands at about 1,700 in the Korean market. With data collected from 358 survey respondents, a conjoint analysis was conducted to identify consumers' preferences of Korean rice in regard to such aspects as producing area, brand, category, and price. We particularly focused on analyzing the consumers' preference of rice brands, with some scenarios to decrease the number of brands. The paper also estimated the virtual market shares of rice brands. As results of the analyses, the paper shows that the grouping of individual rice brands in a city or county under one representative brand is the most preferred by Korean consumers. Even though the suggestion in this paper may not be acceptable to every case of rice brands in the Korean market, the findings might act as a guideline in developing a policy to cut down the number of Korean rice brands.

description: The conductance of disordered wires with symplectic symmetry is studied by a random-matrix approach. It has been shown that the behavior of the conductance in the long-wire limit crucially depends on whether the number of conducting channels is even or odd. We focus on the metallic regime where the wire length is much smaller than the localization length, and calculate the ensemble-averaged conductance and its variance for both the even- and odd-channel cases. We find that the weak-antilocalization correction to the conductance in the odd-channel case is equivalent to that in the even-channel case. Furthermore, we find that the variance dose not depend on whether the number of channels is even or odd. These results indicate that in contrast to the long-wire limit, clear even-odd differences cannot be observed in the metallic regime.

description: The management of public irrigated perimeters has been considered crucial in many countries. In many scientific papers the main problem raised is the process of transference of management from the public sector to the private users. Thus, the objective of this paper is to study CODEVASF’s sixteen public irrigated perimeters in order to evaluate their emancipation process. Both bibliographic research and analysis of Brazilian legislation were done and a methodological proposal was elaborated which allows for evaluation of those perimeters in function of their peculiarities, especially management efficiency, operation and maintenance of their infrastructure, solvency of the producers, profitability of the agricultural activity and soil use. The indicators representative of these items were statistically treated with SPSS software to determine a model for identifying mathematically when a perimeter meets all the emancipation conditions. Results show that the proposed model is adequate and, although there were advances in CODEVASF’s irrigated perimeters management transference process, there are still some difficulties related mainly to inspection and contractual instruments, which suggests the necessity of trying different forms of transference authorized by Brazilian legislation.
Cultural difference in dialectical response style : "how much yes is in your yes?"

description: Cross-cultural variation in response style has been documented by a large body of evidence. The current research follows the perspective that culture importantly influences response style. We have focused on East Asian dialectical thinking, or tendency to tolerate psychological contradiction. In recent years, number of studies have shown dialectical nature of East Asian's cognition, self-concept, well-being, and affect. In addition, these fascinating studies have also shed lights onto dialectical thinkers' response style. In study 1, we investigated and captured the dialectical response style of Japanese and Asian-Canadians in the domains of self-esteem, personality and attitudes, hi three different domains, Japanese and Asian-Canadians responded to positive and reverse items in a less converging manner compared to European-Canadians. Study 2 introduced differential item functioning (DIE) analyses to the study of dialectical response style. We have found that even after individuals are matched on their positive self-esteem, cultural differences in negative self-esteem persist. Conversely, even when negative self-esteem is matched on, cultural differences in positive self-esteem persist. Implications of this research to the use of reverse items in cross-cultural survey research, psychometrics, as well as adding a cautionary note about the validity of cross-cultural survey research are discussed.

description: Fenlong Technology has been applied to increase yield by 20%-50%, improve quality by 5%, and retain water by 100% in 40 kinds of crop cultivated land and saline-alkali land in 26 provinces of China. This paper clarified for the first time the scientific theory system of Fenlong Technology using three-dimensional space resources "Fenlong Agricultural Nature Theory" and the development of the relative "limits" of agricultural growth, which provides a huge power support and natural force for expanding human living spaces. Through inventing and creating a scientific and technological system of farming tools, farming machinery, farming modes, and magic weapons for cultivation, Fenlong Technology can increase grain, promote ecological development, and greatly expand the living spaces of the Chinese nation and achieve sustainable development. Using Fenlong Technology, China has expanded from the current single "cultivated land agriculture" to the "big pattern agriculture" of Fenlong "cultivated land + saline land + degraded grassland + marginal land + desertified land + river water", flexibly used 147 million ha of "three-dimensional space resources" of land, and the newly increased food, meat, and fish can feed 300 million to 400 million people, increased the water storage by 100 billion m3, and reduced the collection of groundwater by 20 million to 60 billion m3.

description: The changes in the worldwide competitive scenario have posed difficulties to the survival of companies, forcing them to establish necessary cooperative relations for maintenance and survival in the markets. However, the lack of coordination and cooperation is considered a classic problem in the beef chain. Taking these assumptions into account, the purpose of the present article is to verify how the organizational network CITE 120, established by a group of beef producers in the state of Rio Grande do Sul (RS), has addressed the environmental demands in the meat production sector and how the systemic relationships for the strengthening of the network’s interests are being promoted and organized. For the purpose of this research in-depth interviews were carried out with members of the network. The results reinforce the remarkable importance for the partners of this type of organizational format, mainly regarding the dissemination of knowledge, organization of learning, raising of competitive advantages in the purchase of inputs, equipments and machines, as well as in the commercialization of beef at more competitive prices. These factors can provide the long-term and medium-term sustainability of the business.

description: When a covariance matrix with a Toeplitz structure is written as the sum of a singular one and a positive scalar multiple of the identity, the singular summand corresponds to the covariance of a purely deterministic component of a time-series whereas the identity corresponds to white noise--this is the Carathéodory-Fejér-Pisarenko (CFP) decomposition. In the present paper we study multivariable analogs for block-Toeplitz matrices as well as for matrices with the structure of state-covariances of finite-dimensional linear systems (which include block-Toeplitz ones). We characterize state-covariances which admit only a deterministic input power spectrum. We show that multivariable decomposition of a state-covariance in accordance with a ``deterministic component + white noise'' hypothesis for the input does not exist in general, and develop formulae for spectra corresponding to singular covariances via decomposing the contribution of the singular part. We consider replacing the ``scalar multiple of the identity'' in the CFP decomposition by a covariance of maximal trace which is admissible as a summand. The summand can be either (block-)diagonal corresponding to white noise or have a ``short-range correlation structure'' correponding to a moving average component. The trace represents the maximal variance/energy that can be accounted for by a process (e.g., noise) with the aforementioned structure at the input, and the optimal solution can be computed via convex optimization. The decomposition of covariances and spectra according to the range of their time-domain correlations is an alternative to the CFP-dictum with potentially great practical significance.

description: This article analyzes the economic growth of agricultural activities and the profile of the agricultural area of the states in the southeastern region of Brazil, between 1995 and 2005. Pointers referring to the farming sector of the region’s states were used. The study shows that the process of economic growth in the region was dynamic in the states of São Paulo and Minas Gerais and was centered on exportation products, mainly sugar cane, soy and maize. In the states of Rio de Janeiro and Espírito Santo, however, there was a decrease of the farming GIP. The region’s exportation guideline presented significant alterations from the decade of 1990, a period in which the exportation of basic products lost importance and was replaced by the manufacturing, a process which reaffirmed the region’s position as the economic center of the country. The regional process of agroindustrialização is characterized by the more intense use of capital technologies, mainly in the sugar cane sector, which has revealed new opportunities in the area of bioproducts and biofuel.

description: In this work, we mainly explore the possibility of charged rho superconductor (CRS) in the presence of parallel magnetic field and rotation within three-flavor Nambu--Jona-Lasino model. By following similar schemes as in the previous studies of charged pion superfluid (CPS), the CRS is found to be favored for both choices of Schwinger phase in Minkovski and curved spaces. Due to the stability of the internal spin structure, charged rho begins to condensate at a smaller threshold of angular velocity than charged pion for the given large magnetic fields. Even the axial vector meson condensation is checked -- the conclusion is that CRS is the robust ground state at strong magnetic field and fast rotation, which actually sustains to very large angular velocity.

description: We study the relation between local unitary (LU) equivalence and local Clifford (LC) equivalence of stabilizer states. We introduce a large subclass of stabilizer states, such that every two LU equivalent states in this class are necessarily LC equivalent. Together with earlier results, this shows that LC, LU and SLOCC equivalence are the same notions for this class of stabilizer states. Moreover, recognizing whether two given stabilizer states in the present subclass are locally equivalent only requires a polynomial number of operations in the number of qubits.
