description: We consider the problem of estimating the distribution function, the density and the hazard rate of the (unobservable) event time in the current status model. A well studied and natural nonparametric estimator for the distribution function in this model is the nonparametric maximum likelihood estimator (MLE). We study two alternative methods for the estimation of the distribution function, assuming some smoothness of the event time distribution. The first estimator is based on a maximum smoothed likelihood approach. The second method is based on smoothing the (discrete) MLE of the distribution function. These estimators can be used to estimate the density and hazard rate of the event time distribution based on the plug-in principle.

Editorial reactions of ten Canadian dailies to the FLQ crisis of 1970
Creators: name: Holdrinet, Gérard Pierre
Publisher: name: University of British Columbia
Year: 2012

description: This study measures and compares the editorial reactions of ten Canadian metropolitan dailies to the FLQ kidnap crisis of 1970, and the specific, important events which occurred within the crisis. Besides comparing the editorial reactions of individual papers, the newspapers are also grouped by language (French and English) and by geographical location, to determine the effect of these two characteristics upon those reactions. The thesis is divided into four chapters, as follows: Methodology, an account of the crisis, the newspapers, and finally the presentation and analysis of the findings. The research method used is content analysis. Five categories are devised, into which are classified the editorial content of the newspapers analyzed. A frequency count method is used, with the theme as recording unit and the paragraph as context unit. Chapter two centers about a short account of the crisis and the selection of important events within the crisis which could be expected to have had some influence upon the editorial reactions of the papers. Chapter three consists of the selection of newspapers to be analyzed, of newspaper characteristics (language and location) which one might expect to have an effect upon editorial reactions, and finally of deferring editorial content for the purpose of this study. The presentation and analysis of findings (Chapter four) is subdivided into two parts-editorial reactions to the entire crisis and editorial reactions to important events within the crisis. It was found that the single greatest determinant of how a newspaper reacted editorially to the crisis was geographic allocation. The papers from Ontario and Quebec put considerable emphasis upon the dangers of excessive reaction by the authorities and upon the need for social reform as a solution to the crisis, whereas the papers from other regions were generally more concerned with the need for law and order. The French papers devoted more editorial space to the crisis than did the English papers but the nature of their reaction was generally similar to that of the English papers of Ontario and Quebec. The French papers greatly increased their editorial content about the crisis after the abduction of Pierre Laporte - the English papers only after the proclamation of the War Measures Act. Before the War Measures Act was proclaimed, all English papers had put a strong emphasis upon the need for law and order. After the proclamation, the English papers of Toronto, Montreal and Ottawa de-emphasized that issue. A summary of the more important findings of the study is presented as a concluding section of Chapter four.

description: The paper is devoted to the theoretical investigation of the magnetodipolar interparticle interaction effect on remagnetization dynamics in moderately concentrated ferrofluids. We consider a homogeneous (without particle aggregates) ferrofluid consisting of identical spherical particles and employ a rigid dipole model, where magnetic moment of a particle is fixed with respect to the particle itself. In particular, for the magnetization relaxation after the external field is instantly switched off, we show that the magnetodipolar interaction leads to the increase of the initial magnetization relaxation time. For the complex ac-susceptibility we find that the this interaction leads to an overall increase of the imaginary susceptibility part and shifts the peak on its frequency dependence towards lower frequencies. Comparing results obtained with our analytical approach (second order virial expansion) to numerical simulation data (Langevin dynamics method), we demonstrate that the employed virial expansion approximation gives a good qualitative description of the ferrofluid magnetization dynamics and provides a satisfactory quantitative agreement with numerical simulations for the dc magnetization relaxation - up to the particle volume fraction c ~ 10% and for the ac-susceptibility - up to c ~ 5 %.

description: The weak currents with respect to the diagonal neutral bosons $Z$,$Z^{\prime}$, and $Z^{\prime\prime}$ of a specific \textbf{$SU(4)_{L}\otimes U(1)_{Y}$} gauge model are computed in detail for all the fermion families involved therein. Our algebraical approach, which is based on the general method of solving gauge models with high symmetries proposed several years ago by Cotăescu, recovers in a non-trivial way all the Standard Model values for current couplings of the traditional leptons and quarks, and predicts plausible values for those of the exotic fermions in the model.

Fast TeV variability in blazars: jets in a jet

description: The fast TeV variability of the blazars Mrk 501 and PKS 2155--304 implies a compact emitting region that moves with a bulk Lorentz factor of Gamma_{em}~100 toward the observer. The Lorentz factor is clearly in excess of the jet Lorentz factors Gamma_j\simless 10 measured on sub-pc scales in these sources. We propose that the TeV emission originates from compact emitting regions that move relativistically {\it within} a jet of bulk Gamma_j~10. This can be physically realized in a Poynting flux-dominated jet. We show that if a large fraction of the luminosity of the jet is prone to magnetic dissipation through reconnection, then material outflowing from the reconnection regions can efficiently power the observed TeV flares through synchrotron-self-Compton emission. The model predicts simultaneous far UV/soft X-ray flares.

description: We study the influence of composition changes on the glass transition of binary hard disc and hard sphere mixtures in the framework of mode coupling theory. We derive a general expression for the slope of a glass transition line. Applied to the binary mixture in the low concentration limits, this new method allows a fast prediction of some properties of the glass transition lines. The glass transition diagram we find for binary hard discs strongly resembles the random close packing diagram. Compared to 3D from previous studies, the extension of the glass regime due to mixing is much more pronounced in 2D where plasticization only sets in at larger size disparities. For small size disparities we find a stabilization of the glass phase quadratic in the deviation of the size disparity from unity.

description: We present promising results for real-time vehicle visual detection, obtained with adaBoost using new original ?keypoints presence features?. These weak-classifiers produce a boolean response based on presence or absence in the tested image of a ?keypoint? (~ a SURF interest point) with a descriptor sufficiently similar (i.e. within a given distance) to a reference descriptor characterizing the feature. A first experiment was conducted on a public image dataset containing lateral-viewed cars, yielding 95% recall with 95% precision on test set. Moreover, analysis of the positions of adaBoost-selected keypoints show that they correspond to a specific part of the object category (such as ?wheel? or ?side skirt?) and thus have a ?semantic? meaning.

description: In many applications one is interested to detect certain (known) patterns in the mean of a process with smallest delay. Using an asymptotic framework which allows to capture that feature, we study a class of appropriate sequential nonparametric kernel procedures under local nonparametric alternatives. We prove a new theorem on the con- vergence of the normed delay of the associated sequential detection procedure which holds for dependent time series under a weak mixing condition. The result suggests a simple procedure to select a kernel from a finite set of candidate kernels, and therefore may also be of interest from a practical point of view. Further, we provide two new theorems about the existence and an explicit representation of optimal kernels minimizing the asymptotic normed delay. The results are illustrated by some examples.

At finite temperature, the model shows the second-order phase transition with mean-field critical exponents for two massless flavors, while in the case of three massless flavors the transition turns out to be of the first order. The topological susceptibility satisfies the anomalous \UA(1) Ward identity and decreases gradually with the temperature increased.

description: Context: Secondary eclipse measurements of transiting extrasolar planets with the Spitzer Space Telescope have yielded several direct detections of thermal exoplanet light. Since Spitzer operates at wavelengths longward of 3.6 um, arguably one of the most interesting parts of the planet spectrum (from 1 to 3 um) is inaccessible with this satellite. This region is at the peak of the planet's spectral energy distribution and is also the regime where molecular absorption bands can significantly influence the measured emission. Aims: So far, 2.2 um K-band secondary eclipse measurements, which are possible from the ground, have not yet lead to secure detections. The aim of this paper is to measure the secondary eclipse of the very hot Jupiter TrES-3b in K-band, and in addition to observe its transit, to obtain an accurate planet radius in the near infrared. Methods: We have used the William Herschell Telescope (WHT) to observe the secondary eclipse, and the United Kingdom Infrared Telescope (UKIRT) to observe the transit of TrES-3b. Both observations involved significant defocusing of the telescope, aimed to produce high-cadence time series of several thousand frames at high efficiency, with the starlight spread out over many pixels. Results: We detect the secondary eclipse of TrES-3b with a depth of -0.241+-0.043% (~6 sigma). This corresponds to a day-side brightness temperature of T_B(2.2um)= 2040+-185 K, which is consistent with current models of the physical properties of this planet's upper atmosphere. The centre of the eclipse seems slightly offset from phase phi=0.5 by Delta_phi=-0.0042+-0.0027, which could indicate that the orbit of TrES-3b is non-circular [abridged].

description: When analysing time series an important issue is to decide whether the time series is stationary or a random walk. Relaxing these notions, we consider the problem to decide in favor of the I(0)- or I(1)-property. Fixed-sample statistical tests for that problem are well studied in the literature. In this paper we provide first results for the problem to monitor sequentially a time series. Our stopping times are based on a sequential version of a kernel-weighted variance-ratio statistic. The asymptotic distributions are established for I(1) processes, a rich class of stationary processes, possibly affected by local nonpara- metric alternatives, and the local-to-unity model. Further, we consider the two interesting change-point models where the time series changes its behaviour after a certain fraction of the observations and derive the associated limiting laws. Our Monte-Carlo studies show that the proposed detection procedures have high power when interpreted as a hypothesis test, and that the decision can often be made very early.
Wilderness management : human waste & water quality
Creators: name: Brassington, Juliette
Publisher: name: University Of Tasmania
Year: 2023

description: Human wastes in wilderness areas have a number of impacts. Many of these impacts relate to inadequate disposal methods which are unable to contain harmful pathogens found in human wastes nor prevent animal contact with them. This situation can lead to contamination of surface waters, thereby posing a public health risk. These issues are compounded by the dramatic rise in visitation to these areas and a lack of research or baseline data from which to make informed management decisions. A case study was undertaken at Pelion Plains in the Tasmanian World Heritage Area to examine the impact of human waste on water quality. Pelion Plains is a heavily used area, and there is anecdotal evidence linking the area to a number of health related problems. Using the traditional indicator method, Faecal coliform levels taken over five sample occasions ranged from 1-410 (cfu) per 100 mL water and Faecal streptococci levels ranged from 1-420 per 100 mL. Results indicate that the water is not suitable for drinking. Currently no warning is provided advising visitors of a potential health risk associated with the consumption of untreated water. The faecal sterol method was also used due to its ability to differentiate human and herbivore faecal matter. Results indicated that contamination was herbivore in origin. Due to lack of (antecedent) rain during sampling, however, results were not considered to be truly representative in this study. A limited macroinvertebrate analysis was also undertaken to provide much needed baseline data, which may be useful as a pollution indicator for the detection of long term ecological impacts. This research has demonstrated that inadequate disposal of human wastes is influencing water quality in a wilderness area, and that associated issues of public health are not being addressed. In particular this research demonstrated that the existing toilets and camping activities at Pelion Plains are implicated in the contamination of surface water which is currently used for drinking.
Sigma-resonance and convergence of chiral perturbation theory

description: The dimensionless parameter $ξ' = M^2/(16 π^2 F^2)$, where $F$ is the pion decay constant in the chiral limit and $M$ is the pion mass at leading order in the quark mass, is expected to control the convergence of chiral perturbation theory applicable to QCD. Here we demonstrate that a strongly coupled lattice gauge theory model with the same symmetries as two-flavor QCD but with a much lighter $σ$-resonance is different. Our model allows us to study efficiently the convergence of chiral perturbation theory as a function of $ξ'$. We first confirm that the leading low energy constants appearing in the chiral Lagrangian are the same when calculated from the $ε$-regime and the $p$-regime. However, $ξ' \lesssim 0.002$ is necessary before 1-loop chiral perturbation theory predicts the data within 1%. However, for $ξ' > 0.0035$ the data begin to deviate qualitatively from 1-loop chiral perturbation theory predictions. We argue that this qualitative change is due to the presence of a light $σ$-resonance in our model. Our findings may be useful for lattice QCD studies.

title: The Effect of Intuition on Creativity as Discussed by Several Individuals of Creative Genius
Creators: name: Campbell, Mary Jean
Publisher: name: Old Dominion University Libraries
Year: 1985

description: When the term intuition came into psychological parlance less than a century ago, the argument began over whether intuition could affect creativity, and whether it, in fact, existed at all as part of cognitive process. This paper will begin with a discussion of the meaning of intuition and some of the implications of that term, address the difficulties inherent in relying on self-report for information, and then turn to the statements of several well-known creative individuals about the role of intuition or intuition-related phenomena in their work.

The selection of creative individuals will be limited to those who have attained fame in the twentieth century, or that time period since the term intuition achieved its current connotations.
Tangential LS-category of K(pi,1)-foliations

description: A K(pi,1)-foliation is one for which the universal covers of all leaves are contractible (thus all leaves are K(pi,1)'s for some pi). In the first part of the paper we show that the tangential Lusternik--Schnirelmann category cat F of a K(pi,1)-foliation F on a manifold M is bounded from below by t-codim F for any t with H_t(M;A) nonzero for some coefficient group A. Since for any C^2-foliation F one has cat F <= dim F by our Theorem 5.2 of [Topology 42 (2003) 603-627], this implies that cat F = dim F for K(pi,1)-foliations of class C^2 on closed manifolds. For K(pi,1)-foliations on open manifolds the above estimate is far from optimal, so one might hope for some other homological lower bound for cat F. In the second part we see that foliated cohomology will not work. For we show that the p-th foliated cohomology group of a p-dimensional foliation of positive codimension is an infinite dimensional vector space, if the foliation is obtained from a foliation of a manifold by removing an appropriate closed set, for example a point. But there are simple examples of K(pi,1)-foliations of this type with cat F < dim F. Other, more interesting examples of K(pi,1)-foliations on open manifolds are provided by the finitely punctured Reeb foliations on lens spaces whose tangential category we calculate. In the final section we show that C^1-foliations of tangential category at most 1 on closed manifolds are locally trivial homotopy sphere bundles. Thus among 2-dimensional C^2-foliations on closed manifolds the only ones whose tangential category is still unknown are those which are 2-sphere bundles which do not admit sections.

Norfolk Island : Pacific periphery
Creators: name: Anderson, Marie-Louise
Publisher: name: University Of Tasmania
Year: 2023

description: This exegesis investigates geographical, historical, political and psychological issues relating to island isolation. The principal focus of this work is on the idea of periphery, which is imagined and experienced in the space between the known and the unknown. The exegesis argues that from the periphery it is possible to encounter both contradictory and related psychological desires of belonging and displacement. During Norfolk Island's history some of the residents have felt the pain of exile while others, paradoxically, have sought and often found their own paradise. The history of settlement on Norfolk Island and the continuing struggle for political independence are important issues discussed in relation to self, identity and community. By exploring physical and psychological issues relating to the nature of isolation, the exegesis and installation simultaneously investigates the concept of discovery, particularly in relation to the desire for freedom, adventure and change.

description: The article examines the sociocultural factors of the spread of corruption in our society: tolerance to corruption, inactivity of citizens, contempt for laws, their denial and disobedience, the complexity of communication between the state and society, insufficient openness of government organizations. It was emphasized that the media, non-governmental organizations, and educational institutions play a major role in shaping the legal consciousness of citizens. Considering the prevalence of corruption in our society, it is proposed to consider measures aimed at creating an intolerant attitude of citizens towards corruption, increasing the legal literacy of the population and involving them in solving problems of society as the main direction in the fight against this evil.

Keywords: corruption, sociocultural factors, law, legal nihilism, transparency of power, mentality, institutions of civil society.
The pathogenesis of epizootic ulcerative syndrome (EUS) with particular reference to factors potentially influencing outbreaks of the disease in the Philippines
Creators: name: Catap, ES
Publisher: name: University Of Tasmania
Year: 2023

description: Epizootic ulcerative syndrome (EUS) outbreaks in the Philippines had been consistently associated with periods of decreasing and fluctuating water temperature usually after the rainy season. Therefore, one of the main objectives of this study was to examine the influence of low and highly fluctuating temperature on the pathogenesis of the disease based on the histopathological and epidermal changes. Also, the influence of water temperature variations on the nonspecific immune responses of a fish exposed to \\({Aphanomyces}\\) \\({invadans}\\) was determined. Moreover, the efficacy of four therapeutic substances to enhance the defense mechanisms of susceptible fish against EUS was assessed. A model of the sequential pathology of EUS was developed and described in three spot gourami \\({Trichogaster}\\) \\({trichopterus}\\) and sand whiting \\({Sillago}\\) \\({ciliata}\\). Both species of fish exhibited histopathological changes typical of EUS, such as chronic granulomatous response and inflammatory cell infiltration in the muscle and skin tissues, at day 8 post-inoculation of 55 to 70 spores/fish. From the results of comparative granuloma counts and percentage of cellular infiltration in a sampled lesion area using image analysis, it was shown that the three-spot gouramis developed a more vigorous response than the sand whiting. Based on the EUS model, the effects of either rapid or gradual decrease in temperature on the histopathology of EUS in sand whiting was documented. Qualitative and quantitative histopathological examinations revealed a marked delay in the inflammatory response of fish maintained at low temperature. EUS lesions were also induced in skin-abraded three-spot gouramis exposed to motile A. invadans zoospores, with higher mortality in fish subjected to daily temperature variations (26 ¬¨‚àûC to 19¬¨‚àûC) than in fish held at 26¬¨‚àûC. Histopathological examination also revealed minimal inflammatory cell infiltration and delayed mycotic granuloma formation with extensive tissue damage in temperature-stressed fish. Fish oil, L-cysteine ethyl ester, yeast glucans and levamisole were trialled as prophylactics against EUS. Only yeast glucans and levamisole gave encouraging results. Results from this study showed that low and fluctuating temperature could affect the host's defense mechanisms against EUS and that preventive measures should be aimed at the maintenance of the epidermal integrity and improvement of the nonspecific immune response of fish.

description: We report on the detection of the secondary eclipse of the very-hot Jupiter OGLE-TR-56b from combined z-band time series photometry obtained with the VLT and Magellan telescopes. We measure a flux decrement of 0.0363+/-0.0091 percent from the combined Magellan and VLT datasets, which indicates a blackbody brightness temperature of 2718 (+127/-107) K, a very low albedo, and a small incident radiation redistribution factor, indicating a lack of strong winds in the planet's atmosphere. The measured secondary depth is consistent with thermal emission, but our precision is not sufficient to distinguish between a black-body emitting planet, or emission as predicted by models with strong optical absorbers such as TiO/VO. This is the first time that thermal emission from an extrasolar planet is detected at optical wavelengths and with ground-based telescopes.

Export instability and political violence in underdeveloped countries
Creators: name: Moul, William Brian
Publisher: name: University of British Columbia

description: There have been few attempts to empirically delineate and assess the importance of "external" or "international" factors in the study of comparative politics and political development. The purpose of this thesis is to examine an "international-national linkage" which has been the subject of Considerable speculation butressed with anecdotal evidence. The linkage is between the short term instability of export proceeds of underdeveloped countries and the amount of political violence with in these countries. The independent variables are export instability, export losses, export instability impact, and the impact of export losses. In the first section of the thesis, the external nature of export instability is discussed. Export instability is not always induced externally. The evidence linking export in stability to domestic economic disturbances and economic disturbances to political violence is presented and discussed in the next section. Domestic economic disturbance is an unmeasured intervening variable in this study. There are many methods of computing the instability of export proceeds. Percentage deviations from annual trend values are used in this thesis, with the trend values computed using five year moving averages. The data sources and various measures of political violence available are assessed in terms of validity and reliability. A composite index of "the total magnitude of civil strife," developed by Gurr and Ruttenberg, is used to measure the amount of political violence. The results of across-sectional correlation analysis for a sample of forty-seven underdeveloped countries indicate zero relationships between the four independent variables and political violence. A lack of covariation within the total sample may obscure significant correlations of opposite sign within specified subsamples. Accordingly, the sample is subdivided into three relatively homogeneous socio-economic regions and four political system types. The extent and direction of the relationships does vary according to region and type of political system. The variation is not large.

description: Motivated by a canonical, QCD Hamiltonian we propose an effective Hamiltonian to represent an arbitrary number of quarks in hadronic bags. The structure of the effective Hamiltonian is discussed and the BCS-type solutions that may represent constituent quarks are presented. The single particle orbitals are chosen as 3-dimensional harmonic oscillators and we discuss a class of exact solutions that can be obtained when a subset of single-particle basis states is restricted to include a certain number of orbital excitations. The general problem, which includes all possible orbital states, can also be solved by combining analytical and numerical methods.

description: The simultaneous investigation of Li and Be in stars is a powerful tool in the study of the evolutionary mixing processes. Here, we present beryllium abundances in stars along the whole evolutionary sequence of the open cluster IC 4651. This cluster has a metallicity of [Fe/H] = +0.11 and an age of 1.2 or 1.7 Gyr. Abundances have been determined from high-resolution, high signal-to-noise UVES spectra using spectrum synthesis and model atmospheres. Lithium abundances for the same stars were determined in a previous work. Confirming previous results, we find that the Li dip is also a Be dip. For post-main-sequence stars, the Be dilution starts earlier within the Hertzsprung gap than expected from classical predictions, as does the Li dilution. Theoretical hydrodynamical models are able to reproduce well all the observed features.

A new activity phase of the blazar 3C 454.3. Multifrequency observations by the WEBT and XMM-Newton in 2007-2008

description: We present and analyse the WEBT multifrequency observations of 3C 454.3 in the 2007-2008 observing season, including XMM-Newton observations and near-IR spectroscopic monitoring, and compare the recent emission behaviour with the past one. In the optical band we observed a multi-peak outburst in July-August 2007, and other faster events in November 2007 - February 2008. During these outburst phases, several episodes of intranight variability were detected. A mm outburst was observed starting from mid 2007, whose rising phase was contemporaneous to the optical brightening. A slower flux increase also affected the higher radio frequencies, the flux enhancement disappearing below 8 GHz. The analysis of the optical-radio correlation and time delays, as well as the behaviour of the mm light curve, confirm our previous predictions, suggesting that changes in the jet orientation likely occurred in the last few years. The historical multiwavelength behaviour indicates that a significant variation in the viewing angle may have happened around year 2000. Colour analysis reveals a complex spectral behaviour, which is due to the interplay of different emission components. All the near-IR spectra show a prominent Halpha emission line, whose flux appears nearly constant. The analysis of the XMM-Newton data indicates a correlation between the UV excess and the soft-X-ray excess, which may represent the head and the tail of the big blue bump, respectively. The X-ray flux correlates with the optical flux, suggesting that in the inverse-Compton process either the seed photons are synchrotron photons at IR-optical frequencies or the relativistic electrons are those that produce the optical synchrotron emission. The X-ray radiation would thus be produced in the jet region from where the IR-optical emission comes.

description: We investigate the boson-fermion duality relation for the case of quantum integrable derivative $δ$-function bose gas. In particular, we find out a dual fermionic system with nonvanishing zero-range interaction for the simplest case of two bosonic particles with derivative $δ$-function interaction. The coupling constant of this dual fermionic system becomes inversely proportional to the product of the coupling constant of its bosonic counterpart and the centre-of-mass momentum of the corresponding eigenfunction.

Squishy Amoeba-Like Objects

Publisher: name: Zenodo
Year: 2019

description: On June 19th, 1970, a group of computer scientists who were inventing the internet referred to key pieces of its proposed design as "squishy amoeba-like objects". Amoebas are porous yet have well-defined boundaries. Thinking about these creatures gives us new ways to think about networks and communities and technology. This talk makes a case for the squishy amoeba-like object as an organizing principle for what is broadly being called "the decentralized web", a web outside of monolithic, monopolistic actors.
Quantum phase transition from an antiferromagnet to a spin liquid in a metal

description: We study quantum phase transitions from easy-plane antiferromagnetic metals to paramagnetic metals in Kondo-Heisenberg lattice systems. If the paramagnetic metal is a fractionalized Fermi liquid then the universal critical properties of the phase transition are unaffected for a weak Kondo coupling even when the Fermi surface intersects the magnetic zone boundary. This is in striking contrast to the conventional theory of phase transitions between paramagnetic and antiferromagnetic metals where any Kondo coupling is strongly relevant, and leads to a Landau-damped `Hertz-Millis' theory. The electron quasi-particle remains well-defined in the quantum critical regime and the critical spin fluctuations only contribute subleading corrections to the various properties of conduction electrons.

Irreducible multiparty correlation can be created by local operations

description: Generalizing Amari's work titled "Information geometry on hierarchy of probability distributions", we define the degrees of irreducible multiparty correlations in a multiparty quantum state based on quantum relative entropy. We prove that these definitions are equivalent to those derived from the maximal von Neaumann entropy principle. Based on these definitions, we find a counterintuitive result on irreducible multiparty correlations: although the degree of the total correlation in a three-party quantum state does not increase under local operations, the irreducible three-party correlation can be created by local operations from a three-party state with only irreducible two-party correlations. In other words, even if a three-party state is initially completely determined by measuring two-party Hermitian operators, the determination of the state after local operations have to resort to the measurements of three-party Hermitian operators.
