description: We investigate the detection prospects for two-neutrino and neutrinoless second order weak decays of $^{124}$Xe -- double electron capture ($0/2ν\text{ECEC}$), electron capture with positron emission ($0/2ν\text{EC}β^+$) and double-positron emission ($0/2νβ^+β^+$) -- in multi-tonne xenon time projection chambers. We simulate the decays in a liquid xenon medium and develop a reconstruction algorithm which uses the multi-particle coincidence in these decays to separate signal from background. This is used to compute the expected detection efficiencies as a function of position resolution and energy threshold for planned experiments. In addition, we consider an exhaustive list of possible background sources and find that they are either negligible in rate or can be greatly reduced using our topological reconstruction criteria. In particular, we draw two conclusions: First, with a half-life of $T_{1/2}^{2ν\text{EC}β^+} = (1.7 \pm 0.6)\cdot 10^{23}\,\text{yr}$, the $2ν\text{EC}β^+$ decay of $^{124}$Xe will likely be detected in upcoming Dark Matter experiments (e.g. XENONnT or LZ), and their major background will be from gamma rays in the detector construction materials. Second, searches for the $0ν\text{EC}β^+$ decay mode are likely to be background-free, and new parameter space may be within the reach. To this end we investigate three different scenarios of existing experimental constraints on the effective neutrino mass. The necessary 500 kg-year exposure of $^{124}$Xe could be achieved by the baseline design of the DARWIN observatory, or by extracting and using the $^{124}$Xe from the tailings of the nEXO experiment. We demonstrate how a combination of $^{124}$Xe results with those from $0νβ^-β^-$ searches in $^{136}$Xe could help to identify the neutrinoless decay mechanism.

description: The query “have you seen me?” accompanies age-progressed pictures of children in the media. We explored whether individuals can recognize the faces of unfamiliar adults after studying their childhood pictures or even be able to match pictures of the same people taken at different ages while viewing them. Participants’ performance was better than chance level in a matching task with several possible targets in view (Experiment 1), as well as in a simple yes/no task comparing pairs of child/adult pictures (Experiment 2). Whether the comparison was the child or the adult version did not make a difference. Not surprisingly, memory performance was also not very good, although, in long-term memory (Experiment 4 and Experiment 5), participants did significantly better after studying children’s pictures and picking out their adult- version pictures than after studying adults’ pictures and picking out their child-version pictures. A similar asymmetry was not observed in short-term memory (Experiment 3). Additionally, we showed an own-gender bias in long-term memory in that performance was better for same- gender pictures in both child-to-adult memory direction and adult-to-child memory direction. The results were discussed within the framework of own-age bias in face recognition and implicit knowledge of aging.

description: Since many years ago, multilateration has been used in precision engineering notably in machine tool and coordinate measuring machine calibration. This technique needs, first, the use of laser trackers or tracking interferometers, and second, the use of nonlinear optimization algorithms to determine point coordinates. Research works have shown the influence of the experimental configuration on measure precision in multilateration. However, the impact of floating-point precision in computations on large-scale multilateration precision has not been addressed. In this work, the effects of numerical errors (rounding and cancellation effects) due to floating-point precision (number of digits) were studied. In order to evaluate these effects in large-scale multilateration, a multilateration measurement system was simulated. This protocol is illustrated with a case study where large distances ($\le$20 m) between pairs of target points were simulated. The results show that the use of multi-precision libraries is recommended to control the propagation of uncertainties during the multilateration computation.

description: O futuro das atividades nas unidades de produção agrícola passa pela sucessão, porém a falta de estrutura, as dificuldades de acesso às políticas voltadas à agricultura familiar, as dificuldades financeiras e a baixa escolaridade dos agricultores são fatores que contribuem para a saída dos jovens do meio rural em busca de trabalho na cidade, o que dificulta a sucessão. Este trabalho teve por objetivo analisar a sucessão no Assentamento Capão Bonito I, em Sidrolândia (MS). Utilizou-se o modelo econométrico de escolha qualitativa, Multinomial Logit (MNL), entrevistando 45 assentados no período de agosto a setembro de 2012. As variáveis transmissão do patrimônio, tempo no meio rural do assentado, se o assentado possui financiamento, se algum filho tem posse de lote e a renda do assentado são as principais determinantes da sucessão no assentamento pesquisado. Foram confirmadas as hipóteses de que quanto menor a renda agrícola, mais se agrava o processo de sucessão, e de que quanto maior o tempo no meio rural, maior será a escolha pela sucessão, no entanto, rejeitou-se a hipótese de que quanto maior o nível educacional, menor a escolha pela sucessão. Como principais limitações estão o receio dos assentados em colaborar com a pesquisa e também as dificuldades estruturais do assentamento. ----- Future activities on farms pass through succession. However, the lack of structure, access difficulties to policies related to family farming, financing difficulties, and poor growers schooling, are factors which contribute to the departure of young people from the countryside to the city, looking for work opportunities and making the succession difficult. The purpose of this study was to analyse the succession at the Capão Bonito I settlement in Sidrolândia, State of Mato Grosso do Sul, Brazil. We used the econometric model of qualitative choice called Multinomial Logit to interview 45 settled people from the month of August to September 2012. The following settlement parameters were estimated: patrimony transfer, duration of the settlement process, financing, land strip possession, and the settled income. The hypotheses of that the succession process becomes worse as low is the farming yield, and of that the choose of succession is greater as longer is the staying time in the countryside, were confirmed. However, the hypothesis of that the succession choosing is lesser as greater is the schooling level was rejected. Therefore, the main limitations are the settled fear in collaborating in the research, as well as structural concerns of the settlement process.

description: The Dicke model, which describes the dipolar coupling between N two-level atoms and a quantized electromagnetic field, seemingly violates gauge invariance in the presence of ultrastrong light-matter coupling, a regime that is now experimentally accessible in many physical systems. Specifically, it has been shown that, while the two-level approximation can work well in the dipole gauge, the Coulomb gauge fails to provide the correct spectra in the ultrastrong coupling regime. Here we show that, taking into account the nonlocality of the atomic potential induced by the two-level approximation, gauge invariance is fully restored for arbitrary interaction strengths, even in the limit of N going to infinity. Finally, we express the Hopfield model, a general description based on the quantization of a linear dielectric medium, in a manifestly gauge invariant form, and show that the Dicke model in the dilute regime can be regarded as a particular case of the more general Hopfield model.

description: In. Istorie, Cultură și Cercetare. Vol. III. Târgoviște: Cetatea de Scaun, 2019, p.243-263., 2019The Sovietisation of daily life in the MSSR was achieved by importing the Soviet totalitarian regime and the social economic ordering of the USSR. The steps taken by the Soviet society from 1920-1930 were covered by the population from the MSSR at a fast pace. Such phenomena as repression, fighting with the enemies of the people, deportations, collectivization, nationalization, atheistic propaganda and so on. in the space between the Prut and the Nistru, were new practices and were carried out, for the most part, by "specialists" from other union republics and from the former Moldovan ASSR, who had Soviet experience. The Sovietisation of daily life in the MSSR took place through severa[ ways: Implementation of the Soviet legislation on the territory of the MSSR; expanding the orga ns of the Communist Party (b) from Moldova and attracting the population in the party as an indispensable element of the career ascension and improving the living conditions; the establishment of the Soviet-type administration with which the population had to contact for the realization of social, economic, politica[, cultural interests; Establishing or replacing the existing education system with the Soviet one; Liquidation of private property; Establishing the command economy; Collectivization; Repressions and deportations as a tool for training and persuading to change to the Soviet way of life; Propaganda of the construction of communism and of the Soviet way of life; Implementation of communist ideology in all spheres, including in private life; Atheist propaganda and condemnation oftraditions and so on. Sovietisation has had an impact on the behaviours, cultu re, and mentality of the population. A society based on communist ''values" was created. The creation of a new man-the "Soviet man"-thinking and acting în accordance with the ideals of communist society was a/so intensely propagated. The Sovietisation of daily life ended in 1953 in the MSSR, but it was not 100% achieved. There have always been elements ofthe material and spiritual cu/ture-considered obsolete or bourgeois by the communist regime, being removed to the periphery of society for the purpose of total liquidation.

description: With recent rapid advances in photonic integrated circuits, it has been demonstrated that programmable photonic chips can be used to implement artificial neural networks. Convolutional neural networks (CNN) are a class of deep learning methods that have been highly successful in applications such as image classification and speech processing. We present an architecture to implement a photonic CNN using the Fourier transform property of integrated star couplers. We show, in computer simulation, high accuracy image classification using the MNIST dataset. We also model component imperfections in photonic CNN and show that the performance degradation can be recovered in a programmable chip. Our proposed architecture provides a large reduction in physical footprint compared to current implementations as it utilizes the natural advantages of optics and hence offers a scalable pathway towards integrated photonic deep learning processors.

description: “3R” principle circular economy emphasizes the technical operation level, while the theoretical viewpoint on value-increasing of circular economy makes deep analysis based on environmental economics. The viewpoint takes for that the evaluation of any circular economic model should consider both the economic value and externalities. If the material units unattached to products in the economic system are circulated with value-increasing as more as possible, more value can be created with lower consumption of resources. The essential principle of circular economy is that the material units within an economic system should go through the multiple production to be circulated with value-increasing, the main purpose of circular economy is that the material units shouldn’t attach to waste going out of the system as much as possible in order to reduce pollution emissions, the economic mechanism of circular economy is that the economic value chain should be used to pull the material units of the system to achieve smooth circulation.
COST-EFFECTIVENESS OF PARENT-CHILD INTERACTION THERAPY (PCIT) IN CLINICS VERSUS HOMES FROM FOUR PERSPECTIVES

description: Parent-Child Interaction Therapy (PCIT) has been shown to be effective in decreasing negative child behaviors when delivered in the traditional setting of clinics. Emerging research suggests that delivering PCIT in clinics and homes can produce similar outcomes. Some providers believe that home PCIT improves the generalization of parenting skills and reduces barriers that may prevent families from engaging in services. Funders may be less likely to invest in home PCIT, however, as they could more concerned about the resources used by providers than parents. Given that different perspectives may not value resources in the same way, we assessed effectiveness and costs of clinic and home PCIT from the Client, Provider, Administrative, and Overall perspectives using multivariate analysis of covariance on listwise deletion and imputed datasets. Previous investigators found that clinic and home PCIT produced similar rates of decrease in the number and intensity of negative behaviors, but that home PCIT had a higher rate of treatment completion. The current study found significant differences in costs for three of the four perspectives, with home PCIT yielding higher costs from the Provider and Overall perspectives, and clinic PCIT yielding higher costs from the Administrative perspective. No significant differences were found in costs from the Client perspective, but this is due to the greater number of sessions, and better treatment completion rate, associated with home PCIT as compared to clinic PCIT. Analyses of the cost-effectiveness ratios (CERs) only indicated significant differences between treatment groups from the Overall and Provider perspectives. All CERs indicated that clinic PCIT cost less per point decrease in the number or intensity of negative behaviors than home PCIT. We conclude that although home PCIT may be more expensive, it is an important option for those families who are unable to travel to and from the clinic due to their child's severe behavior problems and logistical barriers.

description: We have studied the masses for fully open-flavor tetraquark states $bc\bar{q}\bar{s}$ and $sc\bar{q}\bar{b}$ with quantum numbers $J^{P}=0^{+},1^{+}$. We systematically construct all diquark-antiquark interpolating currents and calculate the two-point correlation functions and spectral densities in the framework of QCD sum rule method. Our calculations show that the masses are about $7.1-7.2$ GeV for the $bc\bar{q}\bar{s}$ tetraquark states and $7.0-7.1$ GeV for the $sc\bar{q}\bar{b}$ tetraquarks. The masses of $bc\bar{q}\bar{s}$ tetraquarks are below the thresholds of $\bar{B}_{s}D$ and $\bar{B}_{s}^{*}D$ final states for the scalar and axial-vector channels respectively. The $sc\bar{q}\bar{b}$ tetraquark states with $J^{P}=1^{+}$ lie below the $B_{c}^{+}K^{*}$ and $B_{s}^{*}D$ thresholds. Such low masses for these possible tetraquark states indicate that they can only decay via weak interaction and thus are very narrow and stable.

title: Knowledge management in international development charities

Publisher: name: The Open University
Year: 2011

description: This thesis investigates the effectiveness and potential longevity of Knowledge Management in three international development charities, in order to compare their experiences with the commercial context in which Knowledge Management originated. By this means, the research explores how well, or otherwise, Knowledge Management can be fitted into a different setting. It also throws significant light on the transfer of business practices more generally. Chapter one assesses the evolution of the discipline Knowledge Management. It also provides key information about International Development Charities. Chapter two identifies the theoretical foundations of Knowledge Management as a prescription for organisational effectiveness, together with recommended best practices. Two environmental factors are emphasised: the role of information technology and, given the historic link to Japanese workstyles, ideas about organisational `culture'. In chapter three, the methodology for practical enquiry, derived from organisational system theory, is presented, and the problems in assessing effectiveness are discussed. Chapters four and five provide the substantive outcome of the fieldwork. Patterns that emerge from the data are drawn together in chapter six, highlighting the selective nature of Knowledge Management in application and demonstrating both similarities to and divergences from the original concept. In particular, there are specific challenges posed by the international reach of development charities. The overall conclusions in chapter seven confirm that Knowledge Management undoubtedly chimes with the broad aims of international charities. At the same time, the transferability of Knowledge Management depends crucially upon its adaptability to the organisations' aims, resources, and `culture'. Where it is accepted that knowledge handling is needed to build organisational capacity, then Knowledge Management can provide a framework which, when combined with technological advances, is a tool, rather than the answer, for international charities engaged in the continuing struggle to abolish poverty.

description: The dynamics of a one dimensional growth model involving attachment and detachment of particles is studied in the presence of a localized growth inhomogeneity along with anchored boundary conditions. At large times, the latter enforce an equilibrium stationary regime which allows for an exact calculation of roughening exponents. The stochastic evolution is related to a spin Hamiltonian whose spectrum gap embodies the dynamic scaling exponent of late stages. For vanishing gaps the interface can exhibit a slow morphological transition followed by a change of scaling regimes which are studied numerically. Instead, a faceting dynamics arises for gapful situations.

description: In December 2015, the Central Rural Work Conference put forward the structural reform of agricultural supply side, to ensure the national food security. At present, China's grain production is increasing, the supply and demand structure of grain market is not balanced, and the ineffective supply due to the lack of market supply and demand has caused the problem of structural surplus and structural shortage. And price and quality difference of domestic and international grain is obvious, and the agricultural products in China are overstock, so the reform of agricultural supply side based on food security must be implemented. To adjust structure, reduce stock, reduce cost, increase quality, promote the primary, secondary and tertiary industries convergence will become the focus of China's agricultural supply side structural reform, and we can develop the ecological agriculture, improve the competitiveness of the grain market in price and quality, to ensure food security for the nation.
BREAKING THE MOLD OF TRUE WOMANHOOD: EXPRESSIONS OF FEMININE AGENCY IN THE SCULPTURAL CAREERS OF HARRIET HOSMER, EDMONIA LEWIS, AND VINNIE REAM
Creators: name: Hines, Sarah
Publisher: name: American University
Year: 2023

description: Harriet Hosmer, Edmonia Lewis, and Vinnie Ream were successful female American sculptors active during the second half of the nineteenth century. As women in a traditionally male profession, they negotiated their expressions of feminine propriety and their ambitions carefully. At a time when women were expected to act only within domestic spaces, these three women operated to varying degrees in the public sphere. They had to conform to the expectations of their patrons and meet standards of proper feminine decorum. However, each woman found ways to challenge cultural norms of femininity in their careers and in their work. The careers of Hosmer, Lewis, and Ream occupy spaces of tension and contradiction. Their work simultaneously resisted the restrictive conventions of femininity and conformed to standards of feminine propriety. These three women performed different aspects of ideal femininity, each using it as a tool to create a sort of façade of “true womanhood,” which often allowed them to continue to function with greater agency, having deflected attention from behavior that was considered too masculine.

The results showed that the effect of the direct grain subsidy policy on promoting the rice production performance is declining year by year, largely because drop of scale efficiency. Besides, there are problems of serious redundancy in agricultural subsidy, unreasonable resource allocation, leading to low performance and resource waste of rice production.

This allows to relate lattice estimates of the running quark mass to the renormalization group invariant mass. The result is used in a preliminary computation of the strange quark mass in the theory with two flavors of non-perturbatively improved Wilson quarks. A more detailed discussion of the calculation can be found in [1].

description: The space of holomorphic foliations of codimension one and degree $d\geq 2$ in $\mathbb{P}^n$ ($n\geq 3$) has an irreducible component whose general element can be written as a pullback $F^*\mathcal{F}$, where $\mathcal{F}$ is a general foliation of degree $d$ in $\mathbb{P}^2$ and $F:\mathbb{P}^n\dashrightarrow \mathbb{P}^2$ is a general rational linear map. We give a polynomial formula for the degrees of such components.

description: It is shown on the ground of a simple 6\times 6 neutrino mixing model that one of three conventional sterile (righthanded) neutrinos, if light enough, may be consistently used for explaining a {\it small} LSND effect. Then, it is still considerably heavier than the three active (lefhanded) neutrinos, so that a kind of {\it soft} seesaw mechanism can work. The usual condition that the Majorana lefthanded component of the overall 6\times 6 neutrino mass matrix ought to vanish, {\it implies} the smallness of active-neutrino masses versus sterile-neutrino masses, when three mixing angles between both sorts of neutrinos are small. In the presented model, the mass spectrum of active neutrinos comes out roughly degenerate, lying in the range (5 - 7.5)\times 10^{-2} eV, {\it if} there is a {\it small} LSND effect with the amplitude of the order 10^{-3} and with the mass-squared splitting \sim 1 eV^2.

description: In December 2015, the Central Rural Work Conference put forward the structural reform of agricultural supply side, to ensure the national food security. At present, China's grain production is increasing, the supply and demand structure of grain market is not balanced, and the ineffective supply due to the lack of market supply and demand has caused the problem of structural surplus and structural shortage. And price and quality difference of domestic and international grain is obvious, and the agricultural products in China are overstock, so the reform of agricultural supply side based on food security must be implemented. To adjust structure, reduce stock, reduce cost, increase quality, promote the primary, secondary and tertiary industries convergence will become the focus of China's agricultural supply side structural reform, and we can develop the ecological agriculture, improve the competitiveness of the grain market in price and quality, to ensure food security for the nation.
A Semi-global Hybrid Sensorless Observer for Permanent Magnets Synchronous Machines with Unknown Mechanical Model

description: In this paper, we present a hybrid sensorless observer for Permanent Magnets Synchronous Machines, with no a priori knowledge of the mechanical dynamics and without the typical assumption of constant or slowly-varying speed. Instead, we impose the rotor speed to have a constant (unknown) sign and a non-zero magnitude at all times. For the design of the proposed scheme, meaningful Lie group formalism is adopted to describe the rotor position as an element of the unit circle. This choice, however, leads to a non-contractible state space, and therefore it introduces topological constraints that complicate the achievement of global/semi-global and robust results. In this respect it is shown that the proposed observer, which employs a clock to periodically reset the estimates, is semi-globally practically asymptotically stable, and thus it improves a continuous-time version designed under the same assumptions. As highlighted in the simulation results, the novel hybrid strategy leads to enhanced transient performance, notably without any modification of the gains employed in the continuous-time solution. These features motivate to augment the observer with a discrete-time identifier, leading to significantly faster rotor flux reconstruction.

An exploration of factors potentially associated with the development of childhood feeding disorders

description: Researchers have struggled to define and classify childhood feeding disorders. Literature is limited in its examination of the prevalence, etiology, and symptomology of feeding disorders. The purpose of the current study was to explore factors related to parent and family attitudes, behaviors, and practices that may be associated with the development of a childhood feeding disorder. The current study examined the following three categories of factors: extreme parental attitudes and rules regarding meal and feeding time for children, the lack of regular family meals, and parents’ personal eating attitudes and behaviors. Additionally, the current study explored whether the presence of a feeding disorder during childhood was associated with the later development of an eating disorder during adolescence/adulthood. The sample consisted of 143 mothers and fathers whose children had either clinically significant feeding disorders, or little to no history of food refusal. The data was archival and was based on the parents’ completion of a structured diagnostic interview followed by a series of self-report questionnaires. Findings from the current study suggest that the categories of factors examined are not significantly associated with the development of a childhood feeding disorder. Further, childhood feeding disorders do not seem to be associated with the development of an eating disorder later in life. The results of the current study should be reexamined once a universal diagnostic system for feeding disorders is agreed upon by professionals in the field. Future studies should focus on examining which classification system best represents feeding disorders and exploring the more basic principles of childhood feeding disorders such as prevalence, sociodemographic influencers, and comorbidity rates.

description: SrRuO$_3$, a ferromagnet with an approximately 160\,K Curie temperature, exhibits a $T^2$ dependent dc resistivity below $\approx$ 30 K. Nevertheless, previous optical studies in the infrared and terahertz range show non-Drude dynamics at low temperatures which seem to contradict a Fermi-liquid picture with long-lived quasiparticles. In this work, we measure the low-frequency THz range response of thin films with residual resistivity ratios, $ρ_{300K}/ ρ_{4K} \approx$ 74. Such low disorder samples allow an unprecedented look at the effects of electron-electron interactions on low-frequency transport. At temperatures below 30 K, we found both a very sharp zero-frequency mode which has a width narrower than $k_BT/\hbar$ as well as a broader zero frequency Lorentzian that has at least an order of magnitude larger scattering rate. Both features have temperature dependencies consistent with a Fermi-liquid with the wider feature explicitly showing a T$^2$ scaling. Such two -Drude transport sheds light on previous reports of the violation of Mathielssen's rule and extreme sensitivity to disorder in metallic ruthenates. We consider a number of possibilities for the origin of the two feature optical conductivity including multiband effects that arise from momentum conserving interband scattering and the approximate conservation of a pseudo-momentum that arises from quasi-1D Fermi surfaces.

title: Excursion theory and local times for Bessel and Brownian diffusions: with applications to credit risk

description: By means of excursion theory, the evolution of a continuous Markov process satisfying regularity assumptions is analysed in terms of its behaviour between visits to a recurrent point, for instance the point zero in the state space of Brownian and Bessel diffusions of type reflecting at the origin. As a preliminary conclusion, a sample path of the process can be reconstructed by the excursions away from zero of random finite lengths and the time spent at visits to zero. These two together constitute the core of the work in this thesis. With respect to the zero-free intervals, we study the duration of the excursion in process away from zero by time t, namely the age process, of a Bessel process instantaneously reflected at the origin. The main contribution of our work is the development of a hybrid structural-reduced form model with an endogenous intensity defined by the age process. This model provides a framework for assessing default probabilities within a circumstance of very limited information, assuming that some statistics about a firm are not observable but the time points when they reach certain level are. Results presented include distributional properties for the default time and level as a joint stopping process, by which we discover a decomposition theorem that contributes to exact schemes for simulating the default process. A counting process for monitoring consecutive arrivals of some event driven by the same intensity is also established. Main aspects to be addressed are the properties and the derivations of distributional quantities concerning the interarrival times, the arrival of the nth event and the associated counting process. With respect to the zero set, we construct a continuous family of functionals for the part of time spent at the origin by the age process, namely the local time at zero. It is a well known fact that there is no unified representation for the local time of Markov process, as it can be approximated as a limit of various processes describing the behaviour of trajectories of the underlying process. That being so, the focus and efforts are put on the certain properties of the limit processes served as the approximations, and on the first and second order limit theorems for the convergences to the local time.
