description: Resonant soft x-ray Bragg diffraction at the Tb M4,5 edges and non resonant Bragg diffraction have been used to investigate orbitals in TbB2C2. The Tb 4f quadrupole moments are ordered in zero field below T_N and show a ferroquadrupolar alignment dictated by the antiferromagnetic order. With increasing applied field along [110] the Tb 4f magnetic dipole moments rotate in a gradual manner toward the field. The quadrupole moment is rigidly coupled to the magnetic moment and follows this field-induced rotation. The quadrupolar pair interaction is found to depend on the specific orientation of the orbitals as predicted theoretically and can be manipulated with an applied magnetic field.

description: Η μελέτη ανέλυσε τους τρόπους επίλυσης συγκρούσεων μαθητών με μαθησιακές δυσκολίες σε σύγκριση με τους μαθητές τυπικής ανάπτυξης που φοιτούν σε δημοτικά σχολεία του νομού Χαλκιδικής. Οι συμμετέχοντες της μελέτης ήταν 40 μαθητές με μαθησιακές δυσκολίες και 40 μαθητές τυπικής ανάπτυξης. Οι συμμετέχοντες επιλέχθηκαν με βάση τα σκορ που πέτυχαν στην κλίμακα Μαθησιακής επάρκειας Detroit Test of Learning Aptitude (DTLA-4). Η ανάλυση των δεδομένων πραγματοποιήθηκε μέσω της μη παραμετρικής στατιστικής (Wilcoxon, Spearman’s και Mann Whitney U) με σκοπό την εκτίμηση των διαφορών ανάμεσα στους δύο τύπους μαθητών. Τα αποτελέσματα της μελέτης έδειξαν ότι οι μαθητές με μαθησιακές δυσκολίες με τους μαθητές τυπικής ανάπτυξης διαφέρουν ως προς τον τρόπο κατανόησης του σεναρίου· δηλαδή οι μαθητές με μαθησιακές δυσκολίες δεν μπορούν να αντιληφθούν το σύνολο των γεγονότων και να λάβουν υπόψη τους το σύνολο των παραγόντων που θα βοηθήσουν στην επίλυσή της. Αυτό φαίνεται να σχετίζεται με την χρήση της στρατηγικής του εξαναγκασμού με σκοπό την επίτευξη των στόχων τους αδιαφορώντας για την καλή διατήρηση των σχέσεών τους με την ομάδα των συνομηλίκων. Αντίθετα, οι μαθητές τυπικής ανάπτυξης φαίνεται να κατανοούν περισσότερο το πρόβλημα της σύγκρουσης, αν και αυτό δεν φάνηκε να σχετίζεται με κάποια συγκεκριμένη στρατηγική επίλυσης των συγκρούσεών τους.
description: The study analyzes ways of resolving of pupils with learning disabilities in comparison with pupils with standard development attending the elementary school in the prefecture of Halkidiki. The participants of the study were 40 students with learning disabilities and 40 students with standard development. The participants were selected on the basis of their scores obtained on the scale learning competence Detroit Test of Learning aptitude (DTLA-4). The analysis of data was carried out by means of non-parametric statistics (Wilcoxon, Spearman’s and Mann Whitney U) in order to assess the differences between the two students types. The results of the study showed that the students with learning disabilities to students with standard development differ in their understanding of conflict scenario. In other words, the students with learning difficulties may not understand all the facts and to take into account all the factors which will help to solve it. This seems to be associated with the use of strategy of forcing with a view to achieving the objectives for the preservation of their relations with a group of peers. Instead, the students with standard development seems to understand the problem of the conflict, although this was not related to any particular strategy for resolving conflicts.

description: Αγγλική Περίληψη The emergence of open source software has changed the landscape in the software industry and transformed the open source software to an integral piece of technology and infrastructure of information systems. For this reason, recent years have seen an explosion of interest in the business world around Open Source Enterprise Resource Planning software or simply Open Source ERP. The purpose of the study is to examine the applicability of an Open Source ERP to small businesses that are a major part of the Greek economy. Initially we studied the importance of the ERP systems implementation for managing the enterprises’ supply chain and the possibility of using open-source software to achieve this goal. Then, through a number of available open-source software, an evaluation of their characteristics was carried out, based on certain criteria that were set, in order to select one of them. To draw conclusions an experiment with the chosen software took place in the "HARALABOS KEFALIDIS & Co. "company with the distinctive title «ARTEPLAST». The completion of the work ends with the reference to research findings.

description: The purpose of the present paper is to prove for finitely generated groups of type I the following conjecture of A.Fel'shtyn and R.Hill, which is a generalization of the classical Burnside theorem. Let G be a countable discrete group, f one of its automorphisms, R(f) the number of f-conjugacy classes, and S(f)=# Fix (f^) the number of f-invariant equivalence classes of irreducible unitary representations. If one of R(f) and S(f) is finite, then it is equal to the other. This conjecture plays an important role in the theory of twisted conjugacy classes and has very important consequences in Dynamics, while its proof needs rather sophisticated results from Functional and Non-commutative Harmonic Analysis. We begin a discussion of the general case (which needs another definition of the dual object). It will be the subject of a forthcoming paper. Some applications and examples are presented.

Μεταξύ διεθνισμού και επιβίωσης: Η Comintern και η σοβιετική πολιτική (1919-1943):

description: Σκοπός της μεταπτυχιακής εργασίας ήταν η ανάδειξη της σχέσης μεταξύ της Κομμουνιστικής Διεθνούς και της πολιτικής της ΕΣΣΔ καθόλη τη διάρκεια λειτουργίας της πρώτης (1919-1943). Μελετήθηκαν τα συνέδρια της Διεθνούς και οι αποφάσεις της σε συσχετισμό πάντοτε με τις αντίστοιχες εξελίξεις στην πολιτική της Μόσχας, τόσο στο εσωτερικό όσο και στο εξωτερικό. Κύρια βάση του συλλογισμού ήταν ότι η υποταγή της Comintern στις ανάγκες της σοβιετικής πολιτικής δεν ήταν κάτι προκαθορισμένο αλλά επήλθε μέσα από μακροχρόνιες διαδικασίες. Η Διεθνής δεν ήταν εξαρχής ένα εργαλείο της ΕΣΣΔ, αλλά κατέληξε τέτοιο λόγω των διαρκών αποτυχιών των Κομμουνιστικών Κομμάτων και της συνεχούς ενδυνάμωσης της Σοβιετικής Ένωσης και των μπολσεβίκων τόσο στο διπλωματικό, όσο και στο οικονομικό πεδίο. Η αντίφαση μεταξύ της ιδεολογίας και της ρεαλιστικής πολιτικής αναδείχθηκε πλήρως με το ξέσπασμα του Δευτέρου Παγκοσμίου Πολέμου, οπότε οι ανάγκες της ΕΣΣΔ οδήγησαν την Comintern στη διάλυση, αν και ο μακροχρόνιος δεσμός των δύο πλευρών δείχνει ότι λειτούργησαν περισσότερο παραπληρωματικά παρά αντιθετικά.
description: The aim of this thesis was to highlight the relationship between the Comintern and the Soviet policy throughout the existence of the former (1919-1943). The biggest part of the research was the study of the conferences and decisions of Comintern in conjunction with the corresponding developments in Moscow's policy, both at home and abroad. The main premise was that the subordination of Comintern in the needs of the Soviet policy was not predetermined but something occurred through lengthy procedures. The Third International was initially not a tool of the USSR, but became so because of the persistent failures of the Communist parties and the continued strengthening of the Soviet Union and the Bolsheviks both in the diplomatic and in the economic field. The contradiction between ideology and Realpolitik emerged fully with the outbreak of the Second World War, when the needs of the USSR led to the dissolution of the Comintern, although the long-term bond between the two sides shows that they functioned much more in a complementary than in a contradictory way.

description: We prove that topologically conjugate non-renormalizable polynomials are quasi-conformally conjugate. From this we derive that each such polynomial can be approximated by a hyperbolic polynomial. As a by product we prove that the Julia set of a non-renormalizable polynomials with only hyperbolic periodic points is locally connected, and the Branner-Hubbard conjecture. The main tools are the enhanced nest construction (developed in a previous joint paper with Weixiao Shen) and a lemma of Kahn and Lyubich (for which we give an elementary proof in the real case).

description: The purpose of this thesis is the study of the relinquishment of the judicial means in criminal proceedings. Firstly we examined the relinquishment from an already discharged judicial mean as well as the relinquishment from the right to discharge a judicial mean. We then analyzed the persons entitled to relinquishment as well as the statutory formalities for the proper discharge of the relinquishment. We also examined the limits of the relinquishment and the possibility of revoking the relinquishment. Finally, we examined whether the admissibility of the judicial mean is a prerequisite for a legitimate relinquishment and the consequences of the relinquishment.

description: Using exclusively the 777 full numerical waveforms of the third Binary Black Holes RIT catalog, we reanalyze the ten black hole merger signals reported in LIGO/Virgo's O1/O2 observation runs. We obtain binary parameters, extrinsic parameters, and the remnant properties of these gravitational waves events which are consistent with, but not identical to previously presented results. We have also analyzed three additional events (GW170121, GW170304, GW170727) reported in Venumadhav et al. 2019, and found closely matching parameters. We finally assess the accuracy of our waveforms with convergence studies applied to O1/O2 events and found them adequate for current estimation of parameters.

description: We consider the out-of-equilibrium behavior of a general class of mesoscopic devices composed of several superconducting or/and normal metal leads separated by quantum dots. Starting from a microscopic Hamiltonian description, we provide a non-perturbative approach to quantum electronic transport in the tunneling amplitudes between dots and leads: using the equivalent of a path integral formulation, the lead degrees of freedom are integrated out in order to compute both the current and the current correlations (noise) in this class of systems, in terms of the dressed Green's function matrix of the quantum dots. In order to illustrate the efficiency of this formalism, we apply our results to the "all superconducting Cooper pair beam splitter", a device composed of three superconducting leads connected via two quantum dots, where crossed Andreev reflection operates Cooper pair splitting. Commensurate voltage differences between the three leads allow to obtain expressions for the current and noise as a function of the Keldysh Nambu Floquet dressed Green's function of the dot system. This voltage configuration allows the occurrence of non-local processes involving multiple Cooper pairs which ultimately lead to the presence of non-zero DC currents in an out-of-equilibrium situation. We investigate in details the results for the noise obtained numerically in the specific case of opposite voltages, where the transport properties are dominated by the so called "quartet processes", involving the coherent exchange of two Cooper pairs among all three superconducting terminals. We show that these processes are noiseless in the non-resonant case, and that this property is also observed for other voltage configurations. When the dots are in a resonant regime, the noise characteristics change qualitatively, with the appearance of giant Fano factors.

description: We investigate non-equilibrium two-electron transfer in a model redox system represented by a two-site extended Hubbard model and embedded in a dissipative environment. The influence of the electron-electron interactions and the coupling to a dissipative bosonic bath on the electron transfer is studied in different temperature regimes. At high temperatures Marcus transfer rates are evaluated and at low temperatures, we calculate equilibrium and non-equilibrium population probabilities of the donor and acceptor with the non-perturbative Numerical Renormalization Group approach. We obtain the non-equilibrium dynamics of the system prepared in an initial state of two electrons at the donor site and identify conditions under which the electron transfer involves one concerted two-electron step or two sequential single-electron steps. The rates of the sequential transfer depend non-monotonically on the difference between the inter-site and on-site Coulomb interaction which become renormalized in the presence of the bosonic bath. If this difference is much larger than the hopping matrix element, the temperature as well as the reorganization energy, simultaneous transfer of both electrons between donor and acceptor can be observed.

description: The Taiwan-America Occultation Survey (TAOS) aims to determine the number of small icy bodies in the outer reach of the Solar System by means of stellar occultation. An array of 4 robotic small (D=0.5 m), wide-field (f/1.9) telescopes have been installed at Lulin Observatory in Taiwan to simultaneously monitor some thousand of stars for such rare occultation events. Because a typical occultation event by a TNO a few km across will last for only a fraction of a second, fast photometry is necessary. A special CCD readout scheme has been devised to allow for stellar photometry taken a few times per second. Effective analysis pipelines have been developed to process stellar light curves and to correlate any possible flux changes among all telescopes. A few billion photometric measurements have been collected since the routine survey began in early 2005. Our preliminary result of a very low detection rate suggests a deficit of small TNOs down to a few km size, consistent with the extrapolation of some recent studies of larger (30--100 km) TNOs.

No regrets : the experience of intentional childlessness from the perspective of women at midlife
Creators: name: Minuk, Laurie
Publisher: name: University of British Columbia
Year: 2009

description: A qualitative, phenomenological methodology was used to explore the experience of intentional childlessness from the perspective often women at midlife. The participants were 45 to 52 years of age, believed that they had been physically capable of reproduction but were no longer fertile, and had been in a marriage or relationship where they perceived that they had the opportunity to have children. During individual, in-depth taped interviews, the women described their life experiences of intentional childllessness. Five common themes emerged from the analysis of the data, using a thematic analysis procedure devised by Colaizzi (1978). The themes described the women's sense of being an anomaly, the sense of marginalization, the sense of the ovenvhelrning costs of motherhood, the sense of freedom and autonomy, and the sense of having made the right choice.

Εξετάσαμε το βίαιο και εγκληματικό φαινόμενο καθώς και τους ορισμούς που έχουν διατυπωθεί. Παρακολουθήσαμε την παράλληλη πορεία της βίας και της εγκληματικότητας, με αυτή του ανθρώπου πάνω στη γη. Ο άνθρωπος επιθυμεί να εξηγήσει τη βίαιη συμπεριφορά που εμφανίζει, γι’ αυτό και τη θέτει υπό το πρίσμα της έρευνας. Αρχικά έχουμε φιλοσοφικούς στοχασμούς και με την πάροδο του χρόνου, στη σύγχρονη εποχή, έχουμε τη γένεση των επιστημών όπου μελετούν πλέον τα υπό εξέταση φαινόμενα συστηματικά. Ιστορικά η ανθρώπινη διάνοια και η θρησκεία, υπογραμμίζουν τη διαχρονικότητα και την πολυμορφία τους. Διαπιστώσαμε πως το κακό στη ζωή του ανθρώπου εκφράστηκε επιθετικά, βίαια και εγκληματικά. Ο άνθρωπος εγκληματεί έναντι της ίδιας του της φύσης. Με τη πτώση διασπάται ψυχολογικά. Τελικά πείθεται για τη βίαιη φύση του και επιθυμεί να την περιορίσει. Κοινωνιολογικά, είναι μια τραυματισμένη(σωματικά και ψυχικά) ύπαρξη, θεολογικά τραυμάτισε τη λαμπρότητα του, με την πτώση του από τον παράδεισο. Η ζωή του οφείλει να είναι ένας αγώνας ώστε να πατάξει το κακό, τη βίαιη αυτή παρόρμηση του, να γεμίσει την ανεπάρκεια του με αγάπη, σεβασμό, ειρήνη και αγαθότητα. Έπειτα διαπιστώσαμε μια θετική πλευρά των φαινομένων αυτών, όπου στο σύνολο τους, είδαμε να έχουν αρνητική χροιά.

Examined the violent and criminal activities and their definitions that have been made. Monitoring the parallel paths of violence and crime, with that of the people on earth. The man wishes to explain the violent behavior that displays for self and put under the light of research. First we have philosophical thinking and with the passage of time, in the modern era, we have the birth of sciences, where studying the phenomena. Historical, the human intellect and religion highlight the timelessness and diversity. We found that the evil in human life expressed with aggressive, violence and crime. The man crime against of his own nature. After the fall, distracting psychologically. Finally convince his self for his violent nature and want to restrict it. Sociological, injure his brilliance with the fall from the paradise. His life had to be a fight, in order to banish every evil and violent impulse and fill the void with love, respect and peace. After all, we found a positive aspect of these phenomena, which have almost a negative touch.

description: Since its discovery, Malin 1 has been considered the prototype and most extreme example of the class of giant low surface brightness disk galaxies. Examination of an archival Hubble Space Telescope I-band image reveals that Malin 1 contains a normal stellar disk that was not previously recognized, having a central I-band surface brightness of mu_0 = 20.1 mag arcsec^-2 and a scale length of 4.8 kpc. Out to a radius of ~10 kpc, the structure of Malin 1 is that of a typical SB0/a galaxy. The remarkably extended, faint outer structure detected out to r~100 kpc appears to be a photometrically distinct component and not a simple extension of the inner disk. In terms of its disk scale length and central surface brightness, Malin 1 was originally found to be a very remote outlier relative to all other known disk galaxies. The presence of a disk of normal size and surface brightness in Malin 1 suggests that such extreme outliers in disk properties probably do not exist, but underscores the importance of the extended outer disk regions for a full understanding of the structure and formation of spiral galaxies.

description: We consider permutations of $\{1,...,n\}$ obtained by $\lfloor\sqrt{n}t\rfloor$ independent applications of random stirring. In each step the same marked stirring element is transposed with probability $1/n$ with any one of the $n$ elements. Normalizing by $\sqrt{n}$ we describe the asymptotic distribution of the cycle structure of these permutations, for all $t\ge 0$, as $n\to\infty$.

description: We study the quantum dissipative Duffing oscillator across a range of system sizes and environmental couplings under varying semiclassical approximations. Using spatial (based on Kullback-Leibler distances between phase-space attractors) and temporal (Lyapunov exponent-based) complexity metrics, we isolate the effect of the environment on quantum-classical differences. Moreover, we quantify the system sizes where quantum dynamics cannot be simulated using semiclassical or noise-added classical approximations. Remarkably, we find that a parametrically invariant meta-attractor emerges at a specific length scale and noise-added classical models deviate strongly from quantum dynamics below this scale. Our findings also generalize the previous surprising result that classically regular orbits can have the greatest quantum-classical differences in the semiclassical regime. In particular, we show that the dynamical growth of quantum-classical differences is not determined by the degree of classical chaos.

description: We analyse, following recent work of Roehner, changes in house prices for both the UK and Ireland. We conclude that prices in London have reached a tipping point and prices relative to inflation are set to fall over the next few years. If inflation does not rise then a hard landing seems likely. House prices in the Irish Republic are shown to have broken away from the moderate rise still to be found in Northern Ireland and Dublin has emerged as another global 'hot spot'. An evolution of Dublin house prices similar to that in London can be anticipated. Keywords: Econophysics, house prices, real estate, prediction PACS: 89.65.Gh, 89.90.+n

description: The $\mathcal{PT}$-symmetric non-Hermitian systems have been widely studied and explored both in theory and in experiment these years due to various interesting features. In this work, we focus on the dynamical features of a triple-qubit system, one of which evolves under local $\mathcal{PT}$-symmetric Hamiltonian. A new kind of abnormal dynamic pattern in the entropy evolution process is identified, which presents a parameter-dependent stable state, determined by the non-Hermiticity of Hamiltonian in the broken phase of $\mathcal{PT}$-symmetry. The entanglement and mutual information of a two-body subsystem can increase beyond the initial values, which do not exist in the Hermitian and two-qubit $\mathcal{PT}$-symmetric systems. Moreover, an experimental demonstration of the stable states in non-Hermitian system with non-zero entropy and entanglement is realized on a four-qubit quantum simulator with nuclear spins. Our work reveals the distinctive dynamic features in the triple-qubit $\mathcal{PT}$-symmetric system and paves the way for practical quantum simulation of multi-party non-Hermitian system on quantum computers.

Μετά από μια ιστορική αναδρομή για το πως και από που ξεκίνησε η συγκεκριμένη πρακτική, έγινε αναφορά στον σημαντικό ρόλο που διαδραμάτισαν οι χώρες της Αφρικής. Στη συνέχεια παρουσιάζονται αναλυτικά οι τέσσερις τύποι του Α.Γ.Γ.Ο. όπως και οι αιτίες για τις οποίες συνεχίζεται η πρακτική αυτή μέχρι και σήμερα. Ο Α.Γ.Γ.Ο. αποτελεί παραβίαση των ανθρωπίνων δικαιωμάτων επομένως αναλύεται η νομοθεσία που ισχύει στις διάφορες χώρες του κόσμου αλλά και στην Ελλάδα σχετικά με την πρακτική. Άλλο ένα θέμα που θίγεται είναι οι αρνητικές επιδράσεις που έχει η κλειτοριδεκτομή στη σωματική και ψυχική υγεία των γυναικών και κοριτσιών, όπως επίσης και ο καθοριστικός ρόλος που διαδραματίζουν οι γιατροί. Επιπλέον ένα μέρος της εργασίας ασχολείται με αληθινές ιστορίες κοριτσιών που έχουν υποβληθεί στην πρακτική αλλά και στην περιγραφή της τελετής. Παρουσιάζεται επίσης μια συνέντευξη της Γουόρις Ντίρι, της συγγραφέως του βιβλίου «Το λουλούδι της Ερήμου» που μέσα από την προσωπική της ιστορία έκανε γνωστό το θέμα της κλειτοριδεκτομής. Στα τελευταία κεφάλαια αναφέρονται οι προτεινόμενοι τρόποι για την καταπολέμηση του Α.Γ.Γ.Ο.. Αξίζει να σημειωθεί πως η εργασία περιλαμβάνει πίνακες και στατιστικά στοιχεία.
description: The aim of the present thesis was the study of Female Genital Mutilation (FGM), otherwise Klitoridektomia. I examined the historical facts about FGM and the important role played by African countries. Then I presented the four types of FGM and the reasons that this practice is continuing to exist. FGM is a violation of human rights therefore I analyzed the legislation in Greece and other parts of the world. I also examined the negative effects FGM has on physical and mental health of women and girls, as well as the decisive role played by doctors. A part of the present thesis is dedicated to true stories about FGM and also to the story of Waris Dirie the author of the book “Desert Flower”. Another aim of this study was to examine the ways of how to eliminate Female Genital Mutilation.

description: We consider a vector gauge theory in 2 + 1 dimensions of the type recently proposed by Radzihovsky and Hermele [1] to describe fracton phases of matter. The theory has U(1)XU(1) vector gauge fields coupled to an additional vector field with a non conventional gauge symmetry. We added to the theory scalar matter in order to break the gauge symmetry. We analyze non trivial configurations by reducing the field equations to first order self dual (BPS) equations which we solved numerically. We have found vortex solutions for the gauge fields which in turn generate for the extra vector field non-trivial configurations that can be associated to magnetic dipoles.

description: We report a study by electron paramagnetic resonance (EPR) on the E'_αpoint defect in amorphous silicon dioxide (a-SiO2). Our experiments were performed on gamma-ray irradiated oxygen-deficient materials and pointed out that the 29Si hyperfine structure of the E'_alpha consists in a pair of lines split by 49 mT. On the basis of the experimental results a microscopic model is proposed for the E'_alpha center, consisting in a hole trapped in an oxygen vacancy with the unpaired electron sp3 orbital pointing away from the vacancy in a back-projected configuration and interacting with an extra oxygen atom of the a-SiO2 matrix.

description: Multi-Objective Mixed-Integer Non-Linear Programming problems (MO-MINLPs) appear in several real-world applications, especially in the mechanical engineering field. To determine a good approximated Pareto front for this type of problems, we propose a general hybrid approach based on a Multi-Criteria Branch-and-Bound (MCBB) and Non-dominated Sorting Genetic Algorithm 2 (NSGAII). We present a computational experiment based on a statistical assessment to compare the performance of the proposed algorithm (BnB-NSGAII) with NSGAII using well-known metrics from literature. We propose a new metric, Investment Ratio (IR), that relate the quality of the solution to the consumed effort. We consider five real-world mechanical engineering problems and two mathematical ones to be used as test problems in this experiment. Experimental results indicate that BnB-NSGAII could be a competitive alternative for solving MO-MINLPs.

description: The electromagnetic mean squared radii, _E and _M, of Lambda(1405) are calculated in the chiral unitary model. We describe the excited baryons as dynamically generated resonances in the octet meson and octet baryon scattering. We evaluate values of _E and _M for the Lambda(1405) on the resonance pole and obtain their complex values. We also consider Lambda(1405) obtained by neglecting decay channels. For the latter case, we obtain negative and larger absolute electric mean squared radius than that of typical ground state baryons. This implies that Lambda(1405) has structure that K^- is widely spread around p.

Supersymmetry Breaking with Zero Vacuum Energy in M-Theory Flux Compactifications

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: An attractive mechanism to break supersymmetry in vacua with zero vacuum energy arose in E_8 x E_8 heterotic models with hidden sector gaugino condensate. An H-flux balances the exponentially small condensate on shell and fixes the complex structure moduli. At quantum level this balancing is, however, obstructed by the quantization of the H-flux. We show that the warped flux compactification background in heterotic M-theory can solve this problem through a warp-factor suppression of the integer flux relative to the condensate. We discuss the suppression mechanism both in the M-theory and the 4-dimensional effective theory and provide a derivation of the condensate's superpotential which is free of delta-function squared ambiguities.
