description: Sensory properties are an essential quality aspect when the consumption of fresh tomato is under consideration. The flavor of tomato is defined as a combination of taste sensations (sweetness, sourness), aroma (volatile compounds), and texture (firmness, mealiness), some of which are proven to be affected by insufficient nutrient supply − especially potassium (K). This study intends to undertake a holistic assessment of the K fertilization effect on the flavor of tomato by connecting the use of sensorial and instrumental methods. An optimal K supply significantly increased the sensory descriptors sweetness, sourness, and aroma as well as the instrumental estimated color, firmness, total soluble solids (TSS), titratable acids (TA), and dry matter (DM) in a cultivar-specific manner. The volatile organic compounds (VOCs) were not significantly affected by K fertilization. The evaluation by the panelists confirmed the results of the instru-mental analyses, by which an increment in the fruit quality with rising K supply could be detected. An optimal K supply of 3.66 g/plant could be suggested to increase tomato flavor in the cocktail cultivars studied: Primavera and Yellow Submarine. Cultivar effects should, therefore, be considered for defining the optimal K fertilizer dose that favors high tomato fruit quality and, hence, better flavor.

On Two-Pass Streaming Algorithms for Maximum Bipartite Matching

description: We study two-pass streaming algorithms for Maximum Bipartite Matching (MBM). All known two-pass streaming algorithms for MBM operate in a similar fashion: They compute a maximal matching in the first pass and find 3-augmenting paths in the second in order to augment the matching found in the first pass. Our aim is to explore the limitations of this approach and to determine whether current techniques can be used to further improve the state-of-the-art algorithms. We give the following results: We show that every two-pass streaming algorithm that solely computes a maximal matching in the first pass and outputs a $(2/3+ε)$-approximation requires $n^{1+Ω(\frac{1}{\log \log n})}$ space, for every $ε> 0$, where $n$ is the number of vertices of the input graph. This result is obtained by extending the Ruzsa-Szemerédi graph construction of [GKK, SODA'12] so as to ensure that the resulting graph has a close to perfect matching, the key property needed in our construction. This result may be of independent interest. Furthermore, we combine the two main techniques, i.e., subsampling followed by the Greedy matching algorithm [Konrad, MFCS'18] which gives a $2-\sqrt{2} \approx 0.5857$-approximation, and the computation of \emph{degree-bounded semi-matchings} [EHM, ICDMW'16][KT, APPROX'17] which gives a $\frac{1}{2} + \frac{1}{12} \approx 0.5833$-approximation, and obtain a meta-algorithm that yields Konrad's and Esfandiari et al.'s algorithms as special cases. This unifies two strands of research. By optimizing parameters, we discover that Konrad's algorithm is optimal for the implied class of algorithms and, perhaps surprisingly, that there is a second optimal algorithm. We show that the analysis of our meta-algorithm is best possible. Our results imply that further improvements, if possible, require new techniques.

title: A Narrative Study of the Emotional Processing of a Female Victim of Stalking by an Ex-Intimate Partner
Creators: name: Cockerell, Elspeth
Publisher: name: University of Kent
Year: 2021

description: Background: There is a body of literature which already suggests that being stalked is associated with an increased risk of mental health difficulties, such as elevated anxiety, depression and post-traumatic stress disorder (PTSD) symptoms. However, the current research lacks a detailed picture of the emotional toll that being stalked can take on its victims. Aim: This research aimed to investigate the emotional impact of stalking behaviours on five females by their ex-intimate partners, using a qualitative approach to shed light on emotional experiences embedded in their stories and experiences. Methodology, Methods and Analysis: An in-depth investigation was conducted, using semi-structured interviews with five female students and staff members from the University of Kent. Each was identified as victims of stalking by their ex-intimate partners using a stalking checklist. A narrative inquiry was chosen as the ideal qualitative approach in order to gain insight into how a person experiences a particular phenomenon. The interviews were analysed and interpreted, taking into account the themes and plots that constructed the participants’ stories. The researcher used narrative inquiry based on a thematic approach to study events as described in the words of the participants. The interviews were transcribed and coded, and subsequently organised into themes chosen to best describe the information given. Findings: The findings from this research illustrated that being stalked has an impact on the victim’s ability to process and regulate their emotions in a functional and appropriate manner. Three themes identified were: Stalker Behaviour, Impact of Stalking on the Victim, and Victim Response. Additionally, the use and impact of coercive control by ex-intimate partners during the period of stalking, were important components affecting the emotional responses of victims, as illustrated through the stories they told. The findings support previous theories that being stalked can have a significant detrimental impact on a person’s mental health. The findings offer further insight into the manner in which that emotional impact can occur, and may pave the way for future research into victim response, coercive control and possible deficits in emotional processing and difficulties with emotional regulation, during and after a stalking experience. Limitations and Recommendations: Narrative research is suited to a small sample size, and this study was limited due to the small amount of participants involved. It was also restricted geographically to one location and to a female gender. Further research will be valuable to move beyond these limitations and provide additional insight into an area where there remains much to be discovered about the emotional impact of stalking.

description: A new approach to designing FSS-based LP-CP converters is presented. It is based on the use of FSSs which exhibit dual diagonal symmetry, and a novel 4-port equivalent circuit able to describe the electrical behavior of the cells for the two linear incident polarizations at the same time. The equivalent circuit allows the use of standardized branch line coupler theory to design LP-CP converters comprising a cascade of an arbitrary number of layers, whose synthesis includes the phase and makes it possible to achieve prescribed electrical conditions systematically. A full design procedure has been developed using the new approach and several designs in both transmission and reflection modes are presented and evaluated. It has been proven that single layer reflective converters exhibit large bandwidths as the two reflected field components are in quadrature independently of the frequency. One of these devices was designed and showed an AR<0.2 dB within the band from 21.5 to 28.5 GHz. The reflective LP-CP converter designed was also manufactured and tested, and the measurements were used to validate the design procedure.

description: Like all macroorganisms, plants have to control bacterial biofilm formation on their surfaces. On the other hand, biofilms are highly tolerant against antimicrobial agents and other stresses. Consequently, biofilms are also involved in human chronic infectious diseases, which generates a strong demand for anti-biofilm agents. Therefore, we systematically explored major plant flavonoids as putative anti-biofilm agents using different types of biofilms produced by Gram-negative and Gram-positive bacteria. In Escherichia coli macrocolony biofilms, the flavone luteolin and the flavonols myricetin, morin and quercetin were found to strongly reduce the extracellular matrix. These agents directly inhibit the assembly of amyloid curli fibres by driving CsgA subunits into an off-pathway leading to SDS-insoluble oligomers. In addition, they can interfere with cellulose production by still unknown mechanisms. Submerged biofilm formation, however, is hardly affected. Moreover, the same flavonoids tend to stimulate macrocolony and submerged biofilm formation by Pseudomonas aeruginosa. For Bacillus subtilis, the flavonone naringenin and the chalcone phloretin were found to inhibit growth. Thus, plant flavonoids are not general anti-biofilm compounds but show species-specific effects. However, based on their strong and direct anti-amyloidogenic activities, distinct plant flavonoids may provide an attractive strategy to specifically combat amyloid-based biofilms of some relevant pathogens.

description: The Internet of Things (IoT) is becoming a part of everyday life through its various sensing devices that collect valuable information. The huge number of interconnected heterogeneous IoT devices poses immense challenges, and network softwarization techniques are an adequate solution to these concerns. Software Defined Networking (SDN) and Network Function Virtualization (NFV) are two key softwarization techniques that enable the realization of efficient, agile IoT networks, especially when combined with Machine Learning (ML), mainly Federated Learning (FL). Unfortunately, existing solutions do not take advantage of such a combination to strengthen IoT networks in terms of efficiency and scalability. In this paper, we propose a novel architecture to achieve distributed intelligent network softwarization for IoT, in which SDN, NFV, and ML combine forces to enhance IoT constrained networks.

description: There has been a major controversy over the past seven years about the high-pressure melting curves of transition metals. Static compression (diamond-anvil cell: DAC) experiments up to the Mbar region give very low melting slopes dT_m/dP, but shock-wave (SW) data reveal transitions indicating much larger dT_m/dP values. Ab initio calculations support the correctness of the shock data. In a very recent letter, Belonoshko et al. propose a simple and elegant resolution of this conflict for molybdenum. Using ab initio calculations based on density functional theory (DFT), they show that the high-P/high-T phase diagram of Mo must be more complex than was hitherto thought. Their calculations give convincing evidence that there is a transition boundary between the normal bcc structure of Mo and a high-T phase, which they suggest could be fcc. They propose that this transition was misinterpreted as melting in DAC experiments. In confirmation, they note that their boundary also explains a transition seen in the SW data. We regard Belonoshko et al.'s Letter as extremely important, but we note that it raises some puzzling questions, and we believe that their proposed phase diagram cannot be completely correct. We have calculated the Helmholtz and Gibbs free energies of the bcc, fcc and hcp phases of Mo, using essentially the same quasiharmonic methods as used by Belonoshko et al.; we find that at high-P and T Mo in the hcp structure is more stable than in bcc or fcc.

description: (abridged) We present spectroscopy data for a sample of 14 FUors and 2 TTauri stars observed with the Spitzer Space Telescope or with the Infrared Space Observatory (ISO). Based on the appearance of the 10 micron silicate feature we define 2 categories of FUors. Objects showing the silicate feature in absorption (Category 1) are still embedded in a dusty and icy envelope. The shape of the 10 micron silicate absorption bands is compared to typical dust compositions of the interstellar medium and found to be in general agreement. Only one object (RNO 1B) appears to be too rich in amorphous pyroxene dust, but a superposed emission feature can explain the observed shape. We derive optical depths and extinction values from the silicate band and additional ice bands at 6.0, 6.8 and 15.2 micron. In particular the analysis of the CO_2 ice band at 15.2 micron allows us to search for evidence for ice processing and constrains whether the absorbing material is physically linked to the central object or in the foreground. For objects showing the silicate feature in emission (Category 2), we argue that the emission comes from the surface layer of accretion disks. Analyzing the dust composition reveals that significant grain growth has already taken place within the accretion disks, but no clear indications for crystallization are present. We discuss how these observational results can be explained in the picture of a young, and highly active accretion disk. Finally, a framework is proposed as to how the two categories of FUors can be understood in a general paradigm of the evolution of young, low-mass stars. Only one object (Parsamian 21) shows PAH emission features. Their shapes, however, are often seen toward evolved stars and we question the object's status as a FUor and discuss other possible classifications.

description: The late eighteenth and early nineteenth centuries have long been considered as a formative period for modern Irish political traditions such as nationalism, republicanism and unionism. For Europe it was the time of a turnover in science moving from observation to experiment and from speculation to fact. Richard Kirwan was a well known natural philosopher in Europe and a respected man of science in his time. Throughout all the wars, he was connected with his colleagues in a network reaching across Europe and even to America. Using a few examples, this article is intended to provide an insight how the network worked in a time that was marked by political conflicts and revolutionary events in both science and social life.

description: We consider a two-stage stochastic optimization problem, in which a long-term optimization variable is coupled with a set of short-term optimization variables in both objective and constraint functions. Despite that two-stage stochastic optimization plays a critical role in various engineering and scientific applications, there still lack efficient algorithms, especially when the long-term and short-term variables are coupled in the constraints. To overcome the challenge caused by tightly coupled stochastic constraints, we first establish a two-stage primal-dual decomposition (PDD) method to decompose the two-stage problem into a long-term problem and a family of short-term subproblems. Then we propose a PDD-based stochastic successive convex approximation (PDD-SSCA) algorithmic framework to find KKT solutions for two-stage stochastic optimization problems. At each iteration, PDD-SSCA first runs a short-term sub-algorithm to find stationary points of the short-term subproblems associated with a mini-batch of the state samples. Then it constructs a convex surrogate for the long-term problem based on the deep unrolling of the short-term sub-algorithm and the back propagation method. Finally, the optimal solution of the convex surrogate problem is solved to generate the next iterate. We establish the almost sure convergence of PDD-SSCA and customize the algorithmic framework to solve two important application problems. Simulations show that PDD-SSCA can achieve superior performance over existing solutions.

description: We present in detail the bosonization-refermionization solution of the anisotropic version of the two-channel Anderson model at a particular manifold in the space of parameters of the theory, where we establish an equivalence with a Fermi-Majorana bi-resonant level model. The correspondence is rigorously proved by explicitly constructing the new fermionic fields and Klein factors in terms of the original ones and showing that the commutation properties between original and new Klein factors are of semionic type. We also demonstrate that the fixed points associated to the solvable manifold are renormalization-group stable and generic, and therefore representative of the physics of the original model. The simplicity of the solution found, allows for the computation of the full set of thermodynamic quantities. In particular, we compute the entropy, occupation and magnetization of the impurity as functions of temperature, and identify the different physical energy scales. In absence of external fields, two energy scales appear and, as the temperature goes to zero, a non-trivial residual entropy indicates that the model approaches a universal line of fixed points of non-Fermi liquid type. An external field, even if small, introduces a third energy scale and causes the quenching of the impurity entropy to zero, taking the system to a corresponding Fermi-liquid fixed point.

description: Stellar winds are one of several ways that massive stars can affect the star formation process on local and galactic scales. In this paper we investigate the numerical resolution needed to inflate an energy-driven stellar wind bubble in an external medium. We find that the radius of the wind injection region, $r_{\rm inj}$, must be below a maximum value, $r_{\rm inj,max}$, in order for a bubble to be produced, but must be significantly below this value if the bubble properties are to closely agree with analytical predictions. The final bubble momentum is within 25 per cent of the value from a higher resolution reference model if $χ= r_{\rm inj}/r_{\rm inj,max}$ = 0.1. Our work has significance for the amount of radial momentum that a wind-blown bubble can impart to the ambient medium in simulations, and thus on the relative importance of stellar wind feedback.

description: This paper provides a technical review of position and speed sensorless methods for controlling Brushless Direct Current (BLDC) motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology. Then, in this paper sensorless advances are reviewed and recent developments in this area are introduced with their inherent advantages and drawbacks, including the analysis of practical implementation issues and applications. The study includes a deep overview of state-of-the-art back-EMF sensing methods, which includes Terminal Voltage Sensing, Third Harmonic Voltage Integration, Terminal Current Sensing, Back-EMF Integration and PWM strategies. Also, the most relevant techniques based on estimation and models are briefly analysed, such as Sliding-mode Observer, Extended Kalman Filter, Model Reference Adaptive System, Adaptive observers (Full-order and Pseudoreduced-order) and Artificial Neural Networks.
Complexity, moral reasoning, and attitudes toward capital punishment

description: This study examined several interrelated issues in social-developmental psychology: (a) the relationship between conceptual and integrative complexity; (b) the relationship between conceptual complexity and moral reasoning; (c) the relationship between attitudes toward capital punishment and moral reasoning; (d) the relationship between attitudes toward capital punishment and conceptual and integrative complexity; and (e) the relationship between the levels of moral reasoning that subjects use to substantiate their own, versus an opposing, position on a moral problem (i.e., capital punishment). Participants were 72 university students (from first-year to graduate school) who completed the Paragraph Completion Test (assessing conceptual complexity), wrote an issue composition on capital punishment (assessing integrative complexity and moral reasoning), generated statements supporting and opposing capital punishment (assessing moral reasoning), and responded to a capital punishment attitude questionnaire. Results indicated that the two measures of complexity are comparable--but not equivalent--assessments of the cognitive structures in information processing, and that conceptual complexity and moral reasoning are moderately related. Integrative complexity and attitudes toward capital punishment related in a curvilinear manner with extreme attitudes (both pro and con) characterizing conceptual simplicity and moderate attitudes characterizing increasing complexity. Moral reasoning and attitudes toward capital punishment related in a linear manner with opposition to capital punishment increasing with moral stage. Furthermore, subjects did not always use higher moral reasoning to substantiate their own attitude or position on this issue, rather they used higher moral reasoning when opposing it, regardless of their chosen position. The implications of these findings for the theories of moral reasoning and conceptual and integrative complexity are discussed and suggestions are advanced for the direction of future research.

Quantile tomography: using quantiles with multivariate data

Publisher: name: arXiv
Year: 2008
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: The use of quantiles to obtain insights about multivariate data is addressed. It is argued that incisive insights can be obtained by considering directional quantiles, the quantiles of projections. Directional quantile envelopes are proposed as a way to condense this kind of information; it is demonstrated that they are essentially halfspace (Tukey) depth levels sets, coinciding for elliptic distributions (in particular multivariate normal) with density contours. Relevant questions concerning their indexing, the possibility of the reverse retrieval of directional quantile information, invariance with respect to affine transformations, and approximation/asymptotic properties are studied. It is argued that the analysis in terms of directional quantiles and their envelopes offers a straightforward probabilistic interpretation and thus conveys a concrete quantitative meaning; the directional definition can be adapted to elaborate frameworks, like estimation of extreme quantiles and directional quantile regression, the regression of depth contours on covariates. The latter facilitates the construction of multivariate growth charts---the question that motivated all the development.

Our results reveal a high sensitivity of the junction to the spiral order and indicate the presence of 0-pi quantum phase transitions as function of the spiral wave vector. We find that the chiral magnetic order introduces chiral superconducting triplet pairs that strongly influence the physics in such Josephson junctions, with potential applications in nanoelectronics and spintronics.

description: Engineering is a field of practice that has ties with development, acquisition, and use of technical, scientific and mathematical knowledge to have a grasp of design, development, invention, innovation and the application of materials, machinery, structures, systems, and processes for designed purposes. South Africa is the center of engineering education in Africa as a result of adequate infrastructures that are important for the offering of engineering education as a discipline. With various changes happening in the South African higher education landscape in particular and the nation in general especially within this era of the Fourth industrial revolution, the future of engineering education in South Africa is set to change. This paper is a theoretical analysis of the various concepts which might likely defined the future of engineering education in South Africa. Evidences from established literatures were used in lending support to the major arguments of the paper. With the general economic trend in Africa, environmental challenges, and the rapid development of technologies, the future of engineering education will be influenced. This paper argues that the future of engineering education will have in it three emerging areas which are automation, additive manufacturing, and industrial internet which will influence the discipline. The paper recommends that there is a need for the government to invest heavily in building the knowledge economy, intensify efforts on STEM education which has the ability to contribute to engineering education in South Africa and there is a need to incorporate into the curriculum leadership and management courses, critical thinking, change management, communication, and crisis management.

description: We study the fidelity and the entanglement entropy for the ground states of quantum systems that have infinite-order quantum phase transitions. In particular, we consider the quantum O(2) model with a spin-$S$ truncation, where there is an infinite-order Gaussian (IOG) transition for $S = 1$ and there are Berezinskii-Kosterlitz-Thouless (BKT) transitions for $S \ge 2$. We show that the height of the peak in the fidelity susceptibility ($χ_F$) converges to a finite thermodynamic value as a power law of $1/L$ for the IOG transition and as $1/\ln(L)$ for BKT transitions. The peak position of $χ_F$ resides inside the gapped phase for both the IOG transition and BKT transitions. On the other hand, the derivative of the block entanglement entropy with respect to the coupling constant ($S^{\prime}_{vN}$) has a peak height that diverges as $\ln^{2}(L)$ [$\ln^{3}(L)$] for $S = 1$ ($S \ge 2$) and can be used to locate both kinds of transitions accurately. We include higher-order corrections for finite-size scalings and crosscheck the results with the value of the central charge $c = 1$. The crossing point of $χ_F$ between different system sizes is at the IOG point for $S = 1$ but is inside the gapped phase for $S \ge 2$, while those of $S^{\prime}_{vN}$ are at the phase-transition points for all $S$ truncations. Our work elaborates how to use the finite-size scaling of $χ_F$ or $S^{\prime}_{vN}$ to detect infinite-order quantum phase transitions and discusses the efficiency and accuracy of the two methods.

Two-orbital Systems with Crystal Field Splitting and Interorbital Hopping

description: The nondegenerate two-orbital Hubbard model is studied within the dynamic mean-field theory to reveal the influence of two important factors, i.e. crystal field splitting and interorbital hopping, on orbital selective Mott transition (OSMT) and realistic compound Ca$_{2-x}$Sr$_{x}$RuO$_{4}$. A distinctive feature of the optical conductivity of the two nondegenerate bands is found in OSMT phase, where the metallic character of the wide band is indicated by a nonzero Drude peak, while the insulating narrow band has its Drude peak drop to zero in the mean time. We also find that the OSMT regime expands profoundly with the increase of interorbital hopping integrals. On the contrary, it is shown that large and negative level splitting of the two orbitals diminishes the OSMT regime completely. Applying the present findings to compound Ca$_{2-x}$Sr$_{x}$RuO$_{4}$, we demonstrate that in the doping region from $x=0.2$ to 2.0, the negative level splitting is unfavorable to the OSMT phase.

description: We report the observation of the melting of a vortex lattice in a fast rotating quasi-two dimensional Bose gas, under the influence of thermal fluctuations. We image the vortex lattice after a time-of-flight expansion, for increasing rotation frequency at constant atom number and temperature. We detect the vortex positions and study the order of the lattice using the pair correlation function and the orientational correlation function. We evidence the melting transition by an abrupt change in the decay of orientational correlations, associated to a proliferation of dislocations. Our findings are consistent with the hexatic to liquid transition in the KTHNY scenario for two-dimensional melting.

description: In the diffraction-limited near-field propagation regime, free-space optical quantum key distribution (QKD) systems can employ multiple spatial modes to improve their key rate. Here, we analyze QKD using the non-orthogonal flat-top focused beams. Although they suffer from a rate penalty, their ease of implementation makes them an attractive alternative to the well-studied orthonormal Laguerre-Gauss (LG) modes. Indeed, in the presence of turbulence, the non-orthogonal modes may achieve higher QKD rate than the LG modes.

Painleve-Gullstrand Coordinates for the Kerr Solution
Creators: name: Natario, Jose

Year: 2008
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We construct a coordinate system for the Kerr solution, based on the zero angular momentum observers dropped from infinity, which generalizes the Painleve-Gullstrand coordinate system for the Schwarzschild solution. The Kerr metric can then be interpreted as describing space flowing on a (curved) Riemannian 3-manifold. The stationary limit arises as the set of points on this manifold where the speed of the flow equals the speed of light, and the horizons as the set of points where the radial speed equals the speed of light. A deeper analysis of what is meant by the flow of space reveals that the acceleration of free-falling objects is generally not in the direction of this flow. Finally, we compare the new coordinate system with the closely related Doran coordinate system.

Death in British Columbia 1850-1950
Creators: name: Coates, Colin MacMillan
Publisher: name: University of British Columbia
Year: 2010

description: In British Columbia between 1850 and 1950 attitudes towards death shifted significantly. In the early decades of white settlement, reactions to death resembled the social norms historians have established for other parts of the Western world during the same period. Death occasioned a moment during which the family (and to a lesser extent the larger community) expressed links with the deceased through magnificent funerals and imposing mortuary art. Centred in the family circle, mortality implied both a desirable escape from daily trials and a future reunion with relatives in a heavenly home. By 1920, however, facets of this mentalite had undergone an evolution. Many commentators on modern attitudes argue that contemporary society "denies death." Analyses of personal letters and memoirs, government correspondence and reports, funeral industry records, and epitaph inscriptions illustrate that in British Columbia individuals actually confronted mortality in an intellectual, but not a physical, sense. It was the shunning of physical reminders of mortality, as shown by the popularity of embalming, cremation, caskets and funeral parlors, which permitted this intellectual confrontation. Nondescript cemeteries and monuments and the common use of vitalistic euphemisms stress the continuing life of the deceased in the confines of the memory of the mourner. Such links were entirely individual ones, and the individuality of modern attitudes is also apparent in changing perceptions of health. As emphasis shifted from improving the public's well-being to focussing on personal health, each assumed ultimate responsibility for his or her own health and death. The importance thus placed on the individual is largely a trait of middle class sensibilities. Changes in mortuary practices all stemmed from bourgeois reforms. Indeed, these shifts represented one means by which the middle class fostered its own identity. Establishing a separate, abhorrent rite for paupers, that is those who had rejected the economic structure of society by not providing for their departure from it, the middle class further affirmed' its identity. For twentieth century bourgeois British Columbians, confronting death was an individual, internal, and intellectual exercise.
