New wine in old bottles: Quantum measurement - direct, indirect, weak - with some applications
Creators: name: Svensson, Bengt E. Y.

Year: 2012
Subjects: subject: Quantum Physics (quant-ph)

description: In this, partly pedagogical review, I attempt to give a self-contained overview of the basis of (non-relativistic) QM measurement theory expressed in density matrix formalism. The focus is on applications to the theory of weak measurement, as developed by Aharonov and Vaidman and their collaborators. Their development of weak measurement combined with what they call 'post-selection' - judiciously choosing not only the initial state of a system ('pre-selection') but also its final state - has received much attention recently. Not the least has it opened up new, fruitful experimental vistas, like novel approaches to amplification. But the approach has also attached to it some air of mystery. I will attempt to 'de-mystify' it by showing that (almost) all results can be derived in a straight-forward way from conventional QM. Among other things, I develop the formalism not only to first order but also to second order in the weak interaction responsible for the measurement. This also allows me to derive, more or less as a by-product, the master equation for the density matrix of an open system in interaction with an environment. One particular application I shall treat of the weak measurement is the so called Leggett-Garg inequalities, a k a 'Bell inequalities in time'. I also give an outline, even if rough, of some of the ingenious experiments that the work by Aharonov, Vaidman and collaborators has inspired. If anything is magic in the weak measurement + post-selection approach, it is the interpretation of the so called weak value of an observable. Is it a bona fide property of the system considered? I have no answer to this question; I shall only exhibit the pros and cons of the proposed interpretation.

description: We discuss generalizations of the notion of i) the group of unitary elements of a (real or complex) finite dimensional C*-algebra, ii) gauge transformations and iii) (real) automorphisms, in the framework of compact quantum group theory and spectral triples. The quantum analogue of these groups are defined as universal (initial) objects in some natural categories. After proving the existence of the universal objects, we discuss several examples that are of interest to physics, as they appear in the noncommutative geometry approach to particle physics: in particular, the C*-algebras M_n(R), M_n(C) and M_n(H), describing the finite noncommutative space of the Einstein-Yang-Mills systems, and the algebras A_F=C+H+M_3(C) and A^{ev}=H+H+M_4(C), that appear in Chamseddine-Connes derivation of the Standard Model of particle physics minimally coupled to gravity. As a byproduct, we identify a "free" version of the symplectic group Sp(n) (quaternionic unitary group).

Understanding parapatric range limits in the long-toed salamander, Ambystoma macrodactylum
Creators: name: Lee-Yaw, Julie Anne
Publisher: name: University of British Columbia
Year: 2014

description: Understanding geographic range limits is an outstanding challenge in evolutionary ecology. My goal was to characterize and evaluate factors contributing to parapatric borders in the long-toed salamander (Ambystoma macrodactylum). Using amplified fragment length polymorphism and mitochondrial data, I tested whether currently-recognized subspecies of long-toed salamander are distinct evolutionary units. My results demonstrate that the long-toed salamander consists of at least four divergent lineages. Discordance between these lineages and current subspecies designations, as well as evidence for a cryptic lineage, emphasize the need to reevaluate existing taxonomy prior to conducting studies of species’ range limits. To further understand the distribution of diversity in this system, I explored the role of climate in shaping lineage boundaries. Using spatial data and ecological niche modeling, I asked whether the boundaries between lineages reflect the limits of their respective climatic niches. My results suggest that the different long-toed salamander lineages are ecologically similar and that suitable climatic space for each lineage exists well-beyond shared borders. Although some contact zones coincide with areas where the average climatic suitability for both lineages is low, sites that are highly suitable for each lineage can be found within these regions in all cases. Thus climatic barriers alone are unlikely driving range limits in this system. I next examined the role of hybridization in shaping range limits. I characterized fine-scale patterns of genetic structure in a contact zone between two long-toed salamander lineages. To determine whether there is evidence of hybrid dysfunction, I assayed adult feeding performance in the laboratory. I observed reduced feeding performance in populations coinciding with the extent of mitochondrial introgression but not in populations that are more admixed. These results may be relevant for understanding the limits of introgression for some genes, but not all. Thus the study of range limits in the context of hybrid zones may require consideration of factors governing differential rates of introgression across the genome. This dissertation demonstrates the use of multiple lines of investigation to narrow down the most relevant hypotheses for parapatric range limits and highlights the potential for several factors to ultimately be shaping species’ range limits.

Search for heavy long-lived charged particles in pp collisions at sqrt(s) = 7 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The result of a search for heavy long-lived charged particles produced in pp collisions at sqrt(s) = 7 TeV at the LHC is described. The data sample has been collected using the CMS detector and corresponds to an integrated luminosity of 5.0 inverse femtobarns. The inner tracking detectors are used to define a sample of events containing tracks with high momentum and high ionization energy loss. A second sample of events with high-momentum and high-ionization tracks satisfying muon identification and long time-of-flight criteria is analyzed independently. In both cases, the results are consistent with the expected background estimated from data. The results are used to establish cross section limits as a function of mass within the context of models with long-lived gluinos, scalar top quarks and scalar taus. Cross section limits on hyper-meson particles, containing new elementary long-lived hyper-quarks predicted by a vector-like confinement model, are also presented. Lower limits at 95% confidence level on the mass of gluinos (scalar top quarks) are found to be 1098 (737) GeV. A limit of 928 (626) GeV is set for a gluino (scalar top quark) that hadronizes into a neutral bound state before reaching the muon detectors. The lower mass limit for a pair produced scalar tau is found to be 223 GeV. Mass limits for a hyper-kaon are placed at 484, 602, and 747 GeV for hyper-rho masses of 800, 1200, and 1600 GeV, respectively.

description: Die Maisinzuchtlinie B73 bildet ein komplexes Bouquet volatiler Substanzen das vorrangig aus Sesquiterpenen besteht. Ein Teil davon wird konstitutiv gebildet, ein anderer Teil fakultativ z.B. nach Herbivorie. Die fakultativen Sesquiterpene werden von Terpensynthasen gebildet, welche durch die Fraßschädigung in ihrer Biosynthese induziert werden. Dazu gehört TPS10, das nur in Blättern der Pflanze gebildet wird. Das Ziel der vorliegenden Arbeit war es, den Reaktionsmechanismus dieses Enzyms besser zu verstehen.
description: The maize inbred line B73 forms complex blends of volatiles that consist mainly of sesquiterpenes. While some of the volatiles are constitutively formed most are released after the plant is damaged by a herbivor. The enzyme class responsible for the formation of volatile terpenes are terpene synthases. In maize, most of the herbivor-induced sesquiterpenes are produced by the multiproduct terpene synthase TPS10 which is active in the leaves of herbivore-damaged leaves. This work focused on elucidating the reaction mechanism of the major multiproduct enzyme TPS10.

Isolierung und Charakterisierung eines Tetrahydrofuran abbauenden Stamms Pseudonocardia sp.
Creators: name: Kohlweyer, Renate Ulrike
Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2000
Subjects: Elektronische Publikation

description: Ein Bakterium, das mit 70 mM Tetrahydrofuran (THF) als einziger Kohlenstoff- und Energiequelle wächst, wurde isoliert und mit Stamm K1 benannt. Durch morphologische und chemotaxonomische Untersuchungen sowie Sequenzierung der 16S rDNA wurde Stamm K1 als Pseudonocardia sp. taxonomisch identifiziert. Der größte Verwandtschaftsgrad, der mit einer jeweils 99 %igen Homologie aufgrund von Sequenzvergleichen der 16S rDNA ermittelt wurde, besteht zwischen Stamm K1, Pseudonocardia hydrocarbonoxydans und Pseudonocardia sulfidoxydans. Neben THF und anderen Substraten nutzt Stamm K1 auch Diethylether, Polyethylenglykole, Toluol, γ -Butyrolacton und 4-Hydroxybuttersäure als einzige Kohlenstoff- und Energiequelle. Die beiden letztgenannten Verbindungen sind postulierte Intermediate im THF-Abbauweg. Enzymatische Untersuchungen zeigten, daß permeabilisierte Zellen THF umsetzen, zellfreier Extrakt hingegen nicht. In weiterführenden Arbeiten wurde nach Anionenaustauschromatographie eine für mit THF angezogene Zellen spezifische NADH abhängige Cytochrom-c-Reduktaseaktivität nachgewiesen. Diese Reduktaseaktivität könnte zu einer Monooxygenase gehören, die den einleitenden Schritt im THF-Abbau, wie in der Literatur beschrieben, katalysiert. Für einen biotechnologischen Einsatz des Stamms K1 wurden die physikochemischen Eigenschaften der Zelloberfläche untersucht und charakterisiert. Experimente zeigten, daß Stamm K1 sowohl durch Adhäsion als auch durch Zelleinschluß immobilisiert werden kann.
description: A bacterium capable to grow with 70 mM Tetrahydrofuran (THF) as sole source of carbon and energy was isolated and designated as strain K1. Based on morphological, chemotaxonomic, and sequencing of the 16S rDNA strain K1 was identified as Pseudonocardia sp. Based on comparisons of the 16S rDNA, the highest homologies were found for strain K1 and Pseudonocardia hydrocarbonoxydans and Pseudonocardia sulfidoxydans (with both 99 %). Besides THF and other substrates, strain K1 uses diethyl ether, polyethylene glycoles, toluene, γ -butyrolactone, and 4-hydroxybutyrat as sole source of carbon and energy. The latter two are postulated intermediates in the THF-breakdown. Enzymatic studies showed that permeabilized cells show THF dependant enzymatic activity, whereas no THF dependant enzymatic activity was detected in crude extract. For THF grown cells, a specific NADH dependant cytochrome-c-reductase activity was detected after anion chromatography of crude extract. This cytochrome-c-reductase activity could belong to a monooxygenase which could initiate THF breakdown as postulated in the literature. For a possible biotechnological use, experiments were performed to investigate and characterize the physicochemical characteristics of strain K1s cell surface. Experiments showed that strain K1 can be immobilized by adhesion as well as cell enclosure techniques.

description: We analyse second order (in Riemann curvature) geometric flows (un-normalised) on locally homogeneous three manifolds and look for specific features through the solutions (analytic whereever possible, otherwise numerical) of the evolution equations. Several novelties appear in the context of scale factor evolution, fixed curves, phase portraits, approaches to singular metrics, isotropisation and curvature scalar evolution. The distinguishing features linked to the presence of the second order term in the flow equation are pointed out. Throughout the article, we compare the results obtained, with the corresponding results for un-normalized Ricci flows.

description: I exploit the potential of latent class models for proposing an innovative framework for financial data analysis. By stressing the latent nature of the most important financial variables, expected return and risk, I am able to introduce a new methodological dimension in the analysis of financial phenomena. In my proposal, (i) I provide innovative measures of expected return and risk, (ii) I suggest a financial data classification consistent with the latent risk-return profile, and (iii) I propose a set of statistical methods for detecting and testing the number of groups of the new data classification. The results lead to an improvement in both risk measurement theory and practice and, if compared to traditional methods, allow for new insights into the analysis of financial data. Finally, I illustrate the potentiality of my proposal by investigating the European stock market and detailing the steps for the appropriate choice of a financial portfolio.

A tal fine, sono discusse le principali questioni teorico-pratiche e metodologiche implicate nella creazione di corpora elettronici per lo studio e la didattica dell’interpretazione. Inoltre, sono illustrati due progetti di ricerca appartenenti ai Corpus-based Interpreting Studies (CIS) che hanno portato alla realizzazione di due corpora elettronici di interpretazione: EPIC (European Parliament Interpreting Corpus) e DIRSI-C (Directionality in Simultaneous Interpreting Corpus). Tali risorse linguistiche, la prima trilingue (italiano, inglese e spagnolo), la seconda bilingue (italiano e inglese), con i rispettivi archivi multimediali su cui si basano, offrono molteplici possibilità di indagine e attività didattiche, a conferma del grande potenziale di questo innovativo paradigma di ricerca, frutto dell’incontro interdisciplinare tra la linguistica dei corpora e gli studi sull’interpretazione.
A network-based dynamical ranking system for competitive sports

description: From the viewpoint of networks, a ranking system for players or teams in sports is equivalent to a centrality measure for sports networks, whereby a directed link represents the result of a single game. Previously proposed network-based ranking systems are derived from static networks, i.e., aggregation of the results of games over time. However, the score of a player (or team) fluctuates over time. Defeating a renowned player in the peak performance is intuitively more rewarding than defeating the same player in other periods. To account for this factor, we propose a dynamic variant of such a network-based ranking system and apply it to professional men's tennis data. We derive a set of linear online update equations for the score of each player. The proposed ranking system predicts the outcome of the future games with a higher accuracy than the static counterparts.

Ziel dieser retrospektiven Arbeit war es,die Auswirkungen der HFSRT auf das Gesamtüberleben und die progressionsfreie Zeit der Patienten mit rezidiviertem malignen Gliom WHO III° oder IV°zu untersuchen.Hierzu wurden 35 Patienten betrachtet, die in der Rezidivsituationeine HFSRTan der Universitäts- und Poliklinik für Strahlentherapie Halle von 01/2002 bis 07/2011 erhielten. Das mediane Gesamtüberleben nach HFSRT betrug 8,8 Monate. Es wurde eine progressionsfreie Zeit von 3,8 Monaten im Median beobachtet. Die eigenen Ergebnisse sind mit denen ähnlicher bereits vorliegender Studien vergleichbar. Bei selten auftretenden unerwünschten Wirkungen während der Therapie stellt die HFSRT durch ihre hohe Präzision einwichtiges Therapiekonzept in der Rezidivsituation maligner Gliome dar.

Therefore 35 patients have been investigated who received a HFSRT in a recurrent situation at the University Clinic and Polyclinic Halle, Department for Radiotherapy from 01/2002 until 07/2011. The median overall survival after HFSRT was 8.8 months. A median progression-free time of 3.8 months was observed. These results are comparable with similar studies. Because of its high precision and the rare occurrence of side effects during therapy, HFSRT is an important therapy concept for recurrent malignant glioma.

Patterns and drivers of selection on laying date in song sparrows (Melospiza melodia)
Creators: name: Essak, Martha
Publisher: name: University of British Columbia
Year: 2014

description: Natural selection in the wild has been extensively researched, but few studies have identified the abiotic and biotic drivers of selection or quantified their influence. I characterized and quantified annual selection on laying date in the song sparrow (Melospiza melodia) population of Mandarte Island, British Columbia over 35 years. Selection was approximately linear for annual reproductive success (ARS) and over-winter survival based on cubic splines visualization of fitness surfaces. Fecundity selection (recruited offspring) was roughly 10 times stronger (-0.271 ± 0.031, mean ± SE) than viability selection (-0.028 ± 0.043, mean ± SE). Since opposing selection could constrain evolution, I used multiple measures of fitness, including fecundity measured at sequential offspring life stages, and female over-winter survival, to test if selection was complementary or opposing. Selection favored early breeding through all fitness measures and was therefore complementary. The strength of fecundity selection on recruits was 1.43 times stronger than selection on nestlings, indicating that the effects of early laying were additive and accumulated over time. Despite strong selection and moderate heritability (h² = 0.16), there has been no phenotypic advance of laying date in this population from 1975 to 2010. I also investigated several potential drivers of selection including density, spring temperature, precipitation and the intensity of brood parasitism by brown-headed cowbirds (Molothrus ater), and determined their relative influence on fecundity and viability selection. I found that density was the most influential driver of fecundity selection, and that selection favoring early breeding increased in magnitude at high population density and high intensities of brood parasitism. Because population density and the age and inbreeding structure of this population are correlated, I also included each of these variables as a covariate in calculation of selection differentials, and found weaker selection for some fitness measures. A climate index representing precipitation during the pre-laying period was the most influential driver of over-winter viability selection, with early breeding favored in winters preceded by warm, dry springs, and late breeding favored in winters preceded by cool, wet springs.

description: We determine numerically the single-particle and the two-particle spectrum of the three-state quantum Potts model on a lattice by using the density matrix renormalization group method, and extract information on the asymptotic (small momentum) S-matrix of the quasiparticles. The low energy part of the finite size spectrum can be understood in terms of a simple effective model introduced in a previous work, and is consistent with an asymptotic S-matrix of an exchange form below a momentum scale $p^*$. This scale appears to vanish faster than the Compton scale, $mc$, as one approaches the critical point, suggesting that a dangerously irrelevant operator may be responsible for the behavior observed on the lattice.

description: This paper investigate individual characteristic influencing the risk to engage a new relationship after a union disruption for Italians men. In particular, we analyze the transition from first union and the successive one, for both marriage and cohabitation. Among other characteristics we stress on the effect of son on repartnering possibility and territorial differences . Presence of son are mainly investigated in the analysis of women repartnering but we find that also for men children from previous unions induce a decrease on the risk to engage a new relationship. The decreasing effect on the risk estimates show a temporal dependency with stronger relationship for new union beginning more than two year after first disruption. Our tested hypothesis is that temporal dynamics depend on the way man could be considered the “principal actor” in taking the decision of interrupt first union or suffer this decision.

description: We study the dissipative quantum harmonic oscillator with general non-thermal preparations of the harmonic oscillator bath. The focus is on equilibration of the oscillator in the long-time limit and the additional requirements for thermalization. Our study is based on the exact solution of the microscopic model obtained by means of operator equations of motion, which provides us with the time evolution of the central oscillator density matrix in terms of the propagating function. We find a hierarchy of conditions for thermalization, together with the relation of the asymptotic temperature to the energy distribution in the initial bath state. We discuss the presence and absence of equilibration for the example of an inhomogeneous chain of harmonic oscillators, and illustrate the general findings about thermalization for the non-thermal environment that results from a quench.

The references to Selye's studies, the definition of health as a perfectible process of physical, mental and social well being, and the analysis of work processes according to the Theory of Organizational Action, allow a complete risk evaluation and the primary prevention of work stress. 
Many of the studies of the Organization and Well-being Programme, conducted in the manufacturing, artisanal, tertiary services, hospital and local health care sectors, before the EU norms and the 2004 European Agreements on stress were implemented, make this point clear.

description: We introduce the notion of thermal entropy density, and first obtain the thermal entropy density of any arbitrary spacetime without firstly assuming a temperature or a horizon. The results indicate that gravity possesses thermal effects or therm entropy density possesses effects of gravity. The results also imply that, besides gravity, the thermal entropy density can also be geometrized.

description: Of concern in the paper is a generalized theoretical study of the non-Newtonian characteristics of peristaltic flow of blood through micro-vessels, e.g. arterioles. The vessel is considered to be of variable cross-section and blood to be a Herschel-Bulkley type of fluid. The progressive wave front of the peristaltic flow is supposed sinusoidal/straight section dominated (SSD) (expansion/contraction type); Reynolds number is considered to be small with reference to blood flow in the micro-circulatory system. The equations that govern the non-Newtonian peristaltic flow of blood are considered to be non-linear. The objective of the study has been to examine the effect of amplitude ratio, mean pressure gradient, yield stress and the power law index on the velocity distribution, wall shear stress, streamline pattern and trapping. It is observed that the numerical estimates for the aforesaid quantities in the case of peristaltic transport of the blood in a channel are much different from those for flow in an axisymmetric vessel of circular cross-section. The study further shows that peristaltic pumping, flow velocity and wall shear stress are significantly altered due to the non-uniformity of the cross-sectional radius of blood vessels of the micro-circulatory system. Moreover, the magnitude of the amplitude ratio and the value of the fluid index are important parameters that affect the flow behaviour. Novel features of SSD wave propagation that affect the flow behaviour of blood have also been discussed.

description: A novel approach for highly linear automatic gain control (AGC) in small-signal ampli¯ers is presented in this paper. A HEMT based topology was implemented, biasing the transistor in the transition between the saturated and linear operation regions. Gain control with low distortion is achieved by simultaneous adjustments of the gate to source (Vgs) and drain to source (Vds) voltages, along the line where the second derivative of the transconductance (Gm3) has a null. Comparatively to the traditional approach, with the transistor biased in the saturated region, this ampli¯er has better intermodulation behavior and e±ciency, without important reduction in the gain control range.

description: A complex projective tower or simply a $\mathbb CP$-tower is an iterated complex projective fibrations starting from a point. In this paper we classify all 6-dimensional $\mathbb CP$-towers up to diffeomorphism, and as a consequence, we show that all such manifolds are cohomologically rigid, i.e., they are completely determined up to diffeomorphism by their cohomology rings. We also show that cohomological rigidity is not valid for 8-dimensional $\mathbb CP$-towers by classifying $\mathbb CP^1$-fibrations over $\mathbb CP^3$ up to diffeomorphism. As a corollary we show that such $\mathbb CP$-towers are diffeomorphic if they are homotopy equivalent.

description: We consider inflationary models in which vector fields are responsible for part or eventually all of the primordial curvature perturbation ζ. Such models are phenomenologically interesting since they naturally introduce anisotropies in the probability distribution function of the primordial fluctuations that can leave a measurable imprint in the cosmic microwave background. Assuming that non-Gaussianity is generated due to the superhorizon evolution, we use the δN formalism to do a complete tree level calculation of the non-Gaussianity parameters f_{NL} and τ_{NL} in the presence of vector fields. We isolate the isotropic pieces of the non-Gaussianity parameters, which anyway have contributions from the vector fields, and show that they obey the Suyama-Yamaguchi consistency relation τ^{iso}_{NL}>=(6/5f^{iso}_{NL})^2. Other ways of defining the non-Gaussianity parameters, which could be observationally relevant, are stated and the respective Suyama-Yamaguchi-like consistency relations are obtained.

Subjects: ING-INF/01 Elettronica

description: This paper presents a practical method of extracting the bias dependent parameters of the forward transit time Tf, implemented in the VBIC model used on a GaAs HBT. The work should be of great value for the circuit designers, who want to have an easy practical way of including good model parameters from a few simple measurements. This paper includes an evaluation of the implemented bias dependence of Tf in the VBIC model. The VBIC model is extracted from measurements on a GaAs HBT made by Caswell Technology. The model shows good agreement with these measurements.

description: Purpose: Individuals vary in their ability to learn the sound categories of nonnative languages (nonnative phonetic learning) and to adapt to systematic differences, such as accent or talker differences, in the sounds of their native language (native phonetic learning). Difficulties with both native and nonnative learning are well attested in people with speech and language disorders relative to healthy controls, but substantial variability in these skills is also present in the typical population. This study examines whether this individual variability can be organized around a common ability that we label “phonetic plasticity.”Method: A group of healthy young adult participants (N = 80), who attested they had no history of speech, language, neurological, or hearing deficits, completed two tasks of nonnative phonetic category learning, two tasks of learning to cope with variation in their native language, and seven tasks of other cognitive functions, distributed across two sessions. Performance on these 11 tasks was compared, and exploratory factor analysis was used to assess the extent to which performance on each task was related to the others.Results: Performance on both tasks of native learning and an explicit task of nonnative learning patterned together, suggesting that native and nonnative phonetic learning tasks rely on a shared underlying capacity, which is termed “phonetic plasticity.” Phonetic plasticity was also associated with vocabulary, comprehension of words in background noise, and, more weakly, working memory.Conclusions: Nonnative sound learning and native language speech perception may rely on shared phonetic plasticity. The results suggest that good learners of native language phonetic variation are also good learners of nonnative phonetic contrasts.

description: In this paper, we derive a Darboux transformation of the Hirota and the Maxwell-Bloch(H-MB) system which is governed by femtosecond pulse propagation through an erbium doped fibre and further generalize it to the matrix form of the $n$-fold Darboux transformation of this system. This $n$-fold Darboux transformation implies the determinant representation of $n$-th new solutions of $(E^{[n]},p^{[n]}, η^{[n]})$ generated from known solution of $(E, p,η)$. The determinant representation of $(E^{[n]},p^{[n]} ,η^{[n]})$ provides soliton solutions, positon solutions, and breather solutions (both bright and dark breathers) of the H-MB system. From the breather solutions, we also construct bright and dark rogue wave solutions for the H-MB system, which is currently one of the hottest topics in mathematics and physics. Surprisingly, the rogue wave solution for $p\, and\, η$ has two peaks because of the order of the numerator and denominator of them. Meanwhile, after fixing time and spatial parameters and changing other two unknown parameters $α$ and $β$, we generate a rogue wave shape for the first time.

Discriminant of system of equations

description: What polynomial in the coefficients of a system of algebraic equations should be called its discriminant? We prove a package of facts that provide a possible answer. Let us call a system typical, if the homeomorphic type of its set of solutions does not change as we perturb its (non-zero) coefficients. The set of all atypical systems turns out to be a hypersurface in the space of all systems of k equations in n variables, whose monomials are contained in k given finite sets. This hypersurface B contains all systems that have a singular solution, this stratum is conventionally called the discriminant, and the codimension of its components has not been fully understood yet (e.g. dual defect toric varieties are not classified), so the purity of dimension of B looks somewhat surprising. We deduce it from a similar tropical purity fact. A generic system of equations in a component B_i of the hypersurface B differs from a typical system by the Euler characteristic of its set of solutions. Regarding the difference of these Euler characteristics as the multiplicity of B_i, we turn B into an effective divisor, whose equation we call the Euler discriminant by the following reasons. Firstly, it vanishes exactly at those systems that have a singular solution (possibly at infinity). Secondly, despite its topological definition, there is a simple linear-algebraic formula for it, and a positive formula for its Newton polytope. Thirdly, it interpolates many classical objects (sparse resultant, A-determinant, discriminant of deformation) and inherits many of their nice properties. This allows to specialize our results to generic polynomial maps: the bifurcation set of a dominant polynomial map, whose components are generic linear combinations of finitely many monomials, is always a hypersurface, and a generic atypical fiber of such a map differs from a typical one by its Euler characteristic.
