description: Solitons are self-sustained wavepackets that occur in many physical systems. Their recent demonstration in optical microresonators has provided a new platform for study of nonlinear optical physics with practical implications for miniaturization of time standards, spectroscopy tools and frequency metrology systems. However, despite its importance to understanding of soliton physics as well as development of new applications, imaging the rich dynamical behaviour of solitons in microcavities has not been possible. These phenomena require a difficult combination of high-temporal-resolution and long-record-length in order to capture the evolving trajectories of closely-spaced microcavity solitons. Here, an imaging method is demonstrated that visualizes soliton motion with sub-picosecond resolution over arbitrary time spans. A wide range of complex soliton transient behaviors are characterized in the temporal or spectral domain, including soliton formation, collisions, spectral breathing and soliton decay. This method can serve as a universal visualization tool for understanding complex soliton physics in microcavities.

description: We consider the possibility of observing deviations from the Standard Model gauge-boson self-couplings at a future $500$~GeV $e^+ e^-$ linear collider. We concentrate on the case in which the electroweak symmetry breaking sector is strongly interacting and there are no new resonances within reach of the collider. We find a sensitivity to the anomalous couplings that is two orders of magnitude higher than that achievable at LEP II. We also show how a polarized electron beam extends the reach of the collider, allowing experiments to probe different directions in parameter space.

Emergence of Unorthodox Ownership and Governance Structures in East Asia

Year: 1997
Subjects: International Development

description: This paper examines the nature of the unorthodox ownership and governance structures that are emerging among firms and the way these structures are supporting the remarkable economic growth in the transition economies of East Asia, as represented in particular by China and Vietnam. These economies are embarked on a distinctive process of property rights reform that resists widespread privatization in favour of evolutionary transformation. From the perspective that organizational innovation is an adaptive recombination and ownership is a bundle of rights, this paper focuses on an evaluation of the extent and consistency of property rights reform in the state-owned enterprise sector of these economies. It reveals the features of the ownership and governance structures of Chinese township-village-enterprises and their consequences for liability and incentives and justifies the fact that private entrepreneurs are typically willing to include community authority as an ambiguous owner or shelter within the embrace of state-owned enterprises. The paper also explores the conditions which have motivated the reform, the impact of property rights structure and reform on enterprise performance, and the relationship between adaptability and accountability.

The Determinants of Economic Performance in Transitional Economies

Year: 1997
Subjects: International Development

description: This paper reviews empirical evidence for key matters concerning new patterns of corporate governance and the determinants of economic performance in transitional economies. Many findings reported draw on new and unusual data for large samples of firms in the Baltic Republics, Russia and Bulgaria, and sometimes the data are in the form of panels. In Russia and Bulgaria we find that privatization and early transition typically have not produced fundamental changes in inherited patterns of corporate governance but, rather, have served to strengthen managerial control. Econometric evidence for Russia, the Baltic Republics and Bulgaria points to the beneficial effects of structures that provide for some degree of employee participation and/or employee ownership. For both managerial pay systems and compensation schemes for other workers, econometric evidence of the beneficial effects of schemes which provide for earnings being related to firm performance is reported. In examining restructuring and the search for packages of policy measures that facilitate enhanced enterprise performance, consistent with theory we find evidence of the existence of positive feedback - for example between different ownership structures and forms of compensation. However, in attempting to uncover broad bundles of restructuring initiatives to date empirical work has made only limited progress. Our findings point to the importance of microeconomic factors in determining economic performance and suggests that specific institutional features are an important influence of economic outcomes in different transitional countries and that widely differing ownership structures may be most appropriate when institutional contexts vary.

description: In this paper we consider Multiple-Input-Multiple-Output (MIMO) detection using deep neural networks. We introduce two different deep architectures: a standard fully connected multi-layer network, and a Detection Network (DetNet) which is specifically designed for the task. The structure of DetNet is obtained by unfolding the iterations of a projected gradient descent algorithm into a network. We compare the accuracy and runtime complexity of the purposed approaches and achieve state-of-the-art performance while maintaining low computational requirements. Furthermore, we manage to train a single network to detect over an entire distribution of channels. Finally, we consider detection with soft outputs and show that the networks can easily be modified to produce soft decisions.
title: Short Term Temporal and Spatial Variability of Phytoplankton in the Elizabeth River

Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98
publisherIdentifierScheme: ROR
Year: 1987

description: This study was designed to evaluate short-term temporal and spatial components of phytoplankton variability within a tidal estuarine system, in reference to natural changes in the local environment.

Multiple water samples were collected weekly from October to December 1984 at 4 stations in different branches, or sections, of the Elizabeth River. Collection of chlorophyll~ data was structured to fit an analysis of variance, while the phytoplankton species and their environmental relationships were analyzed using multivariate techniques.

Lower chlorophyll a concentrations from 0.75 to 2.87 ug/1 were characteristic of the Main Stem and Southern Branch, while higher values of 1.27 to 22.58 ug/1 were in the Western and Eastern Branches. Results indicated that distances of from 6 to 14 km between stations had a greater effect on biomass variability than daily or weekly changes in the physico-chemical environment. Slack water conditions also had a significant (p<.001) effect on chlorophyll a distributions, with higher values associated with slack-before-flood, or low water conditions.

The phytoplankton was dominated by diatoms (e.g. Skeletonema costatum), pico-nanoplankton and cryptomonads. Total abundance was greater in October than December, and was higher in the Eastern and Western branches, which were identified as the high biomass areas. Biomass estimates based on cell volume were greater during December, which corresponded to an increase of diatoms.

Results from cluster analysis revealed a similar temporal separation of environmental and phytoplankton species abundance samples. Samples collected in October and December were more dissimilar than samples collected from the 4 sites. canonical variate analysis suggested that different groups and abundance levels of phytoplankton species corresponded to different ranges of environmental conditions in the River. The six week period between collections had a greater influence on species abundance patterns than mesoscale spatial lengths of from 6 to 14 km.

On nilspace systems and their morphisms

description: A nilspace system is a generalization of a nilsystem, consisting of a compact nilspace X equipped with a group of nilspace translations acting on X. Nilspace systems appear in different guises in several recent works, and this motivates the study of these systems per se as well as their relation to more classical types of systems. In this paper we study morphisms of nilspace systems, i.e., nilspace morphisms with the additional property of being consistent with the actions of the given translations. A nilspace morphism does not necessarily have this property, but one of our main results shows that it factors through some other morphism which does have the property. As an application we obtain a strengthening of the inverse limit theorem for compact nilspaces, valid for nilspace systems. This is used in work of the first and third named authors to generalize the celebrated structure theorem of Host and Kra on characteristic factors.

description: In this paper, 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-30%PT) single crystal samples were poled using an alternating current (electric field) poling (ACP) method. Compared to the traditional poling method, the piezoelectric coefficient, free and clamped dielectric constants were improved more than 21%. X-ray diffraction result suggests the existence of monoclinic phase (MA) in ACP samples and piezoresponse force microscopy (PFM) result further depicts the finer engineered domain structures. The ACP sample also showed the unique phase transition sequences during the depoling process. Our work could provide a novel domain engineered method to enhance piezoelectric properties of PMN-PT single crystal. Piezoelectric and dielectric properties of relaxor-PT single crystals can be significantly enhanced by employing the new alternating current poling method, attributing to the unique heterogenous domain structure containing unprecedented domain wall density.
Leptogenesis in a Realistic Supersymmetric Model of Inflation with a Low Reheat Temperature

description: We discuss leptogenesis in a realistic supersymmetric model of inflation with a low reheat temperature 1-10 GeV. The lepton asymmetry is generated by a decaying right handed sneutrino, which is produced after inflation during preheating. The inflationary model is based on a simple variant of the Next-to-Minimal Supersymmetric Standard model (NMSSM) which solves the μproblem, called \phiNMSSM, where the additional singlet ϕplays the role of the inflaton in hybrid (or inverted hybrid) type models. The model is invariant under an approximate Peccei-Quinn symmetry which also solves the strong CP problem, and leads to an invisible axion with interesting cosmological consequences. We show how the baryon number of the universe and the nature of cold dark matter are determined by the same parameters controlling the strong CP problem, the μproblem and the neutrino masses and mixing angles.

Year: 1997
Subjects: International Development

description: Towards the Abyss? The Political Economy of Emergency in Haiti analyzes the various factors that have contributed to create a protracted humanitarian emergency situation in Haiti. The first section deals with the economic causes, the interplay between population growth, erosion and falling rural incomes, the failure of import substitution in manufacturing and the rise and near destruction (during the 1991-94 sanctions episode) of the export assembly sector. Thereafter the role of politics is examined: the degeneration of government into a kleptocracy during the nineteenth century and the perpetuation of the predatory state until the present. The economic consequences of this are highlighted. The third section deals with the antagonistic relation between the state and the masses, the exploitation of the latter by the former and the failure to stimulate development of the state. Section four analyzes the open conflict between the rulers and the population from 1986 to 1994, the failure to break away from the predatory state, the rise and fall of Jean- Beitrand Aristide and the fatal impact on the economy of the 1991 coup d'etat and the ensuing international economic sanctions. Finally the most important present problems are examined: the fragile judicial system, the weak economy and the failure to obtain even a minimum consensus in politics. All these may in the future contribute to put Haiti back into an acute crisis situation.

Community and Village-Based Provision of Key Social Services: A Case Study of Tanzania

Publisher: name: Unknown
Year: 1997
Subjects: International Development

description: The first part of the paper describes steps which Tanzania took in order to provide key social services to her people. Tanzania made great efforts within the ujamaa socialist system to provide free social services for rural as well as urban people, regardless of their income level. Even after the decline of Tanzanian economy the party-led government tried to maintain and improve social services but nonetheless could not prevent the deterioration of the education and health services nor that of the water and sanitation systems, which had been built with the assistance of foreign development agents. The paper analyses the export liberalization measures, the different phases of economic recovery programmes, the structural adjustment programme with its priority social action, and the recent World Bank Human Development Programme. The second part presents a case study of social services provision in two south-eastern regions of Tanzania, Mtwara and Lindi, which on the basis of statistics are among the poorest in the country. The study and the analysis of the new emphasis on decentralization and on local government which follows in the latter part of the paper, are based on the first-hand field experience of the author. Following the section on new participatory bottom-up experiments, describing the partnership of the World Bank and several foreign development agents, the paper brings out the basic contradictions between the 'traditional' and the 'modern' in social services provision and the difficulty that any development efforts face in trying to integrate people's own understanding and practice of sharing in service provision with the externally introduced models. The different ways in which rural people do share in giving services are elaborated, and it is shown that credit must be given to these sharing practices, as new systems of cost sharing are developed. The conclusion brings out the need to make detailed analyses (based on participatory action research) of the division of wealth in rural communities so that those already heavily involved in self-help work or who provide many kinds of services, can be identified and their contributions registered. The people who belong to the wealthy quintile but manage to escape regular cost-sharing practices, need to be identified and charged according to their means.

description: A full picture of tensile deformation mechanism evolution in the FCC-to-HCP transformation-induced plasticity high entropy alloy (TRIP-HEA) was revealed by real-time in situ neutron diffraction. Three transition points, i.e. the triggering of TRIP in the FCC phase and the activation of single and multiple twinning in the HCP phase, were identified to result in significant stress redistribution. Accordingly, four deformation stages with distinct phase-specific work-hardening behaviors were recognized. It was concluded that the easily-triggered persisting TRIP and the work-hardening potential of the HCP contribute together to the persisting bulk work-hardening. The deformation mechanism evolution and phase-specific work-hardening behaviors of the FCC-to-HCP TRIP-HEA were unraveled, which provided a comprehensive understanding of the TRIP-assisted superior strength and ductility.

Eurocentric Beauty Ideals

description: This abstract examines the impact of one-dimensional beauty standards perpetuated by the media on women's perceptions of beauty, particularly focusing on the intricate relationship between beauty ideals and hair texture in African American (AA) women. The pervasive influence of a white-dominant culture has historically rendered the natural, tightly coiled texture of black hair a source of shame and discomfort for AA women, contributing to a complex narrative shaped by external representations (Collins, 2002; Bekk et al., 2017; Montle, 2020; Gentles-Peart, 2018).

Within this context, the abstract delves into the phenomenon of internalization, exploring how representations of beauty that diverge from natural, tightly coiled black hair often lead to the internalization of rejecting such hair as inherently "natural" (Banks, 2000). This internalization, rooted in Eurocentric ideals, compels AA women to varying degrees towards hair-straightening and weave wearing. These practices, deemed imperative within the Eurocentric beauty paradigm, reinforce the narrative that tightly coiled, kinky hair is unacceptable, unkempt, and unsightly (Collins, 2002; Montle, 2020).

The narrative seeks to unravel the intricate dynamics at play in the intersection of beauty standards, hair texture, and cultural identity for AA women. By scrutinizing the historical and contemporary implications of these beauty ideals, the abstract aims to contribute to a nuanced understanding of the multifaceted challenges faced by AA women in navigating societal expectations and embracing their natural hair texture

description: By modeling quantum chaotic dynamics with ensembles of random operators, we explore howmachine learning learning algorithms can be used to detect pseudorandom behavior in qubit systems.We analyze samples consisting of pieces of correlation functions and find that machine learningalgorithms are capable of determining the degree of pseudorandomness which a system is subjectto in a precise sense. This is done without computing any correlators explicitly. Interestingly,even samples drawn from two-point functions are found to be sufficient to solve this classificationproblem. This presents the possibility of using deep learning algorithms to explore late time behaviorin chaotic quantum systems which have been inaccessible to simulation.

description: Cyclic codes are an important class of linear codes, whose weight distribution have been extensively studied. Most previous results obtained so far were for cyclic codes with no more than three zeroes. Inspired by the works \cite{Li-Zeng-Hu} and \cite{gegeng2}, we study two families of cyclic codes over $\mathbb{F}_p$ with arbitrary number of zeroes of generalized Niho type, more precisely $\ca$ (for $p=2$) of $t+1$ zeroes, and $\cb$ (for any prime $p$) of $t$ zeroes for any $t$. We find that the first family has at most $(2t+1)$ non-zero weights, and the second has at most $2t$ non-zero weights. Their weight distribution are also determined in the paper.

Radiative atom-atom interactions in optically dense media: Quantum corrections to the Lorentz-Lorenz formula

description: Generalized single-atom Maxwell-Bloch equations for optically dense media are derived taking into account non-cooperative radiative atom-atom interactions. Applying a Gaussian approximation and formally eliminating the degrees of freedom of the quantized radiation field and of all but a probe atom leads to an effective time-evolution operator for the probe atom. The mean coherent amplitude of the local field seen by the atom is shown to be given by the classical Lorentz-Lorenz relation. The second-order correlations of the field lead to terms that describe relaxation or pump processes and level shifts due to multiple scattering or reabsorption of spontaneously emitted photons. In the Markov limit a nonlinear and nonlocal single-atom density matrix equation is derived. To illustrate the effects of the quantum corrections we discuss amplified spontaneous emission and radiation trapping in a dense ensemble of initially inverted two-level atoms and the effects of radiative interactions on intrinsic optical bistability in coherently driven systems.

description: We evaluate the constraints on anomalous trilinear gauge-boson couplings that can be obtained from the study of electron-positron annihilation into $W$ pairs at a facility with either the electron beam longitudinally polarized or both electron and positron beams transversely polarized. The energy ranges considered in the analysis are the ones relevant to the next-linear collider and to LEP~200. We discuss the possibilities of a model independent analysis of the general $CP$ conserving anomalous effective Lagrangian, as well as its restriction to some specific models with reduced number of independent couplings. The combination of observables with initial and final state polarizations allows to separately constrain the different couplings and to improve the corresponding numerical bounds.

Floquet-Markov description of the parametrically driven, dissipative harmonic quantum oscillator

description: Using the parametrically driven harmonic oscillator as a working example, we study two different Markovian approaches to the quantum dynamics of a periodically driven system with dissipation. In the simpler approach, the driving enters the master equation for the reduced density operator only in the Hamiltonian term. An improved master equation is achieved by treating the entire driven system within the Floquet formalism and coupling it to the reservoir as a whole. The different ensuing evolution equations are compared in various representations, particularly as Fokker-Planck equations for the Wigner function. On all levels of approximation, these evolution equations retain the periodicity of the driving, so that their solutions have Floquet form and represent eigenfunctions of a non-unitary propagator over a single period of the driving. We discuss asymptotic states in the long-time limit as well as the conservative and the high-temperature limits. Numerical results obtained within the different Markov approximations are compared with the exact path-integral solution. The application of the improved Floquet-Markov scheme becomes increasingly important when considering stronger driving and lower temperatures.

description: We study the sensitivity to the CP/T-violation search in the presence of ambiguities of the theoretical parameters. Three generations of neutrinos are considered. The parameters whose ambiguities are considered are the differences of the squared masses, the mixing angles, and the density of matter. We first consider the statistics that are sensitive to the genuine CP-violation effect originating from the imaginary coupling. No ambiguity of the parameters is considered in this part. It is argued that the widely-adopted usual statistics are not necessarily sensitive to the genuine CP-violation effect. Two statistics that are sensitive to the imaginary coupling are proposed. The qualitative difference between these statistics and the usual one are discussed. Next we proceed to the case where the ambiguity of the parameters is present. The sensitivity of the CP-violation search is greatly spoiled when the baseline length is longer than about one thousand kilometers, which turns out to be due to the ambiguity of the matter effect. Thus the CP-violation search by use of CP conjugate channels turns out to require a low energy neutrino and short baseline length. It is also shown that such a loss of sensitivity is avoided by using T-conjugate oscillation channels.

Long-time dynamics of spontaneous parametric down-conversion and quantum limitations of conversion efficiency

description: We analyze the long-time quantum dynamics of degenerate parametric down-conversion from an initial sub-harmonic vacuum (spontaenous down-conversion). Standard linearization of the Heisenberg equations of motions fails in this case, since it is based on an expansion around an unstable classical solution and neglects pump depletion. Introducing a mean-field approximation we find a periodic exchange of energy between the pump and subharmonic mode goverened by an anharmonic pendulum equation. From this equation the optimum interaction time or crystal length for maximum conversion can be determined. A numerical integration of the 2-mode Schr"odinger equation using a dynamically optimized basis of displaced and squeezed number states verifies the characteristic times predicted by the mean-field approximation. In contrast to semiclassical and mean-field predictions it is found that quantum fluctuations of the pump mode lead to a substantial limitation of the efficiency of parametric down-conversion.

Φάνηκε πως το εισόδημα αποτελεί ένα σημαντικό παράγοντα στην αιτιολόγηση των διαφοροποιήσεων που καταγράφονται στην κατανάλωση υγειονομικών πόρων μεταξύ των διαφόρων χωρών. Επιπρόσθετα το μέρος του GDP που αναλογεί στην κατανάλωση υγειονομικών πόρων στον χώρο της υγείας στις αναπτυγμένες χώρες είναι συνήθως αυξημένο έναντι των αναπτυσσόμενων χωρών. Ως εκ τούτου, όταν το επίπεδο της ανάπτυξης αυξάνεται, αυξάνονται επίσης και οι υγειονομικοί πόροι που καταναλώνονται. Το σύνολο των συγγραφέων συμφωνούν στο ότι η κατανάλωση οικονομικών υγειονομικών πόρων έχει θετικό αντίκτυπο στη διαμόρφωση του επιπέδου υγείας ομάδων με χαμηλά εισοδήματα. Επίσης αναφέρουν πως η κατανάλωση πόρων από τις διάφορες κυβερνήσεις διαδραματίζει σημαντικό παράγοντα στο χώρο της υγείας. Χρησιμοποιώντας δημογραφικά και υγειονομικά δεδομένα, δηλώνουν πως η κατανομή υγειονομικών πόρων μπορεί να μειώσει σε εθνικό πλέον επίπεδο και με σημαντικό τρόπο την βρεφική θνησιμότητα. Ταυτόχρονα, ολοένα και περισσότερες χώρες θέτουν στοχευμένες πολιτικές διαχείρισης των παρεχόμενων υπηρεσιών υγείας, λαμβάνοντας υπ’ όψη πως χώρες που καταγράφουν αυξημένα επίπεδα κατανάλωσης υγειονομικών πόρων έχουν καταφέρει να επιτύχουν μείωση των συνοδών δεικτών θνησιμότητας. Η ανάλυση του συσχετισμού ανάμεσα στο κόστος υγειονομικών παροχών, την οικονομική πρόοδο και τη παιδική θνησιμότητα επιτυγχάνει εν τω βάθει διερεύνηση της αξιολόγησης του επιπέδου υγείας.

description: In the context of texture 4 - zero and texture 5 - zero hierarchical quark mass matrices, CP violating asymmetry in $B^o_d({\bar B}^o_d) \to ψK_S$ (sin2$β$) has been evaluated by considering quark masses at $m_Z$ scale. For a particular viable texture 4 - zero mass matrix the range of sin2βis: 0.27 - 0.60 and for the corresponding texture 5 - zero case it is 0.31 - 0.59. Further our calculations reveal a crucial dependence of sin2$β$ on light quark masses as well as the phase in this sector.

description: Several studies have indicated an increase in men's mortality in East Germany between 1989 and 1991 in the wake of the reunification of 1990. For some age-groups, death rates soared by up to thirty per cent. This study investigates the evolution and the causes of such a short term demographic crisis. A preliminary analysis clearly indicates that the reported mortality growth is not just a statistical artefact that could have been due to administrative and statistical adjustments after reunification. The theories generally advanced to explain mortality crises have therefore been tested on the East German case. The hypothesis that the death crisis is related to psychosocial stress and to economic uncertainty does appear to be plausible. The drastic political, social, and economic changes which took place during the first years of the transition from the socialist to the market economy might have caused much individually experienced stress and, in turn, an increase in mortality. The hypothesis is evaluated using detailed regional cause-of-death statistics as well as individual level micro data. The cause-of-death data indicate a rising relevance of circulatory and heart problems, as well as of alcohol and accident-related deaths amongst the age-groups most affected by the hardship of the transition. We find further confirmation for the psychosocial stress explanation in a positive causation between individual health satisfaction and stress and economic uncertainty in the individual level data
