description: In this work, the Intermodulation Distortion (IMD) produced by RF MEMS capacitors is studied. It is demonstrated that due to their non-linear behaviour, parallel-plate MEMS capacitors generate  5th order tones along with 3rd order IMD products. It is shown that MEMS linear models, restricted to small displacements of the MEMS membrane, neglect 5th order distortion while underestimate 3rd order tones, when high voltages are considered. A numerical non-linear model for simulating intermodulation is presented and validated by means of measurements for the general 2-tone case. Generation of 3rdand 5th IMD products is also demonstrated in MEMS driven by digitally-modulated communication signals. A measurement system is proposed in order to characterize IMD generation in RF MEMS capacitors excited by two RF tones as well as by digitally-modulated signals (QPSK).

description: It is proven that each indecomposable injective module over a valuation domain $R$ is polyserial if and only if each maximal immediate extension $\widehat{R}$ of $R$ is of finite rank over the completion $\widetilde{R}$ of $R$ in the $R$-topology. In this case, for each indecomposable injective module $E$, the following invariants are finite and equal: its Malcev rank, its Fleischer rank and its dual Goldie dimension. Similar results are obtained for chain rings satisfying some additional properties. It is also shown that each indecomposable injective module over one Krull-dimensional local Noetherian rings has finite Malcev rank. The preservation of Goldie dimension finiteness by localization is investigated too.

description: This paper presents a structure of MEMS capacitor providing independence of its nominal capacity and tuning range from the applied RF signal power. The capacitor includes a third parallel plate acting as an electrode to which an extra DC voltage is applied to compensate for the self-actuation effect. This means that the device can be used in many applications working under different RF power conditions, without changing its performance – nominal capacity and tuning range –. Capacitor design concept and simulations are provided. It has been manufactured using a standard surface-micromachining MEMS technology. Experimental results are presented, validating the concept and demonstrating its feasibility and advantages.

description: According to the no-hair theorem, astrophysical black holes are fully characterized by their masses and spins and are described by the Kerr metric. This theorem can be tested observationally by measuring (at least) three different multipole moments of the spacetimes of black holes. In this paper, we calculate the profiles of fluorescent iron lines emitted from the accretion flows around black hole candidates within a framework that allows us to perform the calculation as a function of its mass and spin as well as of a free parameter that measures potential deviations from the Kerr metric. We show that such deviations lead to line profiles that are significantly altered and may exhibit a modified flux ratio of the two peaks in their characteristic double-peaked shape. We also show that the disk inclination can be measured independently of the spin and the deviation parameter at low to intermediate inclination angles as in the case of Kerr black holes. We estimate the precision that near-future X-ray missions such as Astro-H and ATHENA+ are required to achieve in order to resolve deviations from the Kerr metric in iron line profiles and show that constraints on such deviations will be strongest for rapidly spinning black holes. More generally, we show that measuring the line profile with a precision of ~5% at disk inclinations of 30 or 60 degrees constraints the deviation parameter to order unity for values of the spin a>0.5M.
description: 10 pages, 7 figures, accepted for publication in ApJ. Includes the additional result that the disk inclination can be measured independently of the spin and the deviation parameter at low to intermediate inclinations.

description: The tunneling dynamics in relativistic strong-field ionization is investigated with the aim to develop an intuitive picture for the relativistic tunneling regime. We demonstrate that the tunneling picture applies also in the relativistic regime by introducing position dependent energy levels. The quantum dynamics in the classically forbidden region features two time scales, the typical time that characterizes the probability density's decay of the ionizing electron under the barrier (Keldysh time) and the time interval which the electron spends inside the barrier (Eisenbud-Wigner-Smith tunneling time). In the relativistic regime, an electron momentum shift as well as a spatial shift along the laser propagation direction arise during the under-the-barrier motion which are caused by the laser magnetic field induced Lorentz force. The momentum shift is proportional to the Keldysh time, while the wave-packet's spatial drift is proportional to the Eisenbud-Wigner-Smith time. The signature of the momentum shift is shown to be present in the ionization spectrum at the detector and, therefore, observable experimentally. In contrast, the signature of the Eisenbud-Wigner-Smith time delay disappears at far distances for pure quasistatic tunneling dynamics.

Indeed, we show that the existence of a $λ$-supercompact cardinal $κ$ such that $2^λ\geq θ$ is equiconsistent with the existence of a $λ$-supercompact cardinal that is also $θ$-tall. We also prove some basic facts about the large cardinal notion of tallness with closure.

Immigrants as Symbolic Assailants: Crimmigration and Its Discontents
Creators: name: Jiang, Jize
name: Erez, Edna
Publisher: name: University of Illinois at Chicago
Year: 2023
Subjects: subject: Law
subject: FOS: Law

description: Despite little evidence of an immigration-crime nexus, many American jurisdictions have adopted a punitive approach to undocumented immigrants and an increasingly restrictive and exclusive system of immigration control. The extensive deployment of criminal justice measures to address the immigration “problem” led to the growth of a crimmigration apparatus—a mesh of immigration and criminal justice systems. Drawing on extant literature and applying the framework of the penal field, the article examines the social dynamics, processes, and consequences of crimmigration. It is argued that the portrayal of immigrants as “symbolic assailants” has facilitated the creation and operation of crimmigration under the guise of crime prevention rather than for addressing terrorism and national security—the presumed purpose of utilizing crimmigration practices. The current configuration of crimmigration across the United States is the interactive product of minority threat, partisan politics, and federalism of the American government system, which have jointly formed a “multilayered patchwork” of immigration control. The article first outlines the analytical framework; reviews the social construction of immigrant “criminality”; and describes the punitive and exclusive laws, policies, and enforcement practices established as responses to this “threat.” The dilemmas, contradictions, and contestations associated with crimmigration, including collateral impacts on immigrants, their families and communities, and the criminal justice system, are analyzed; and policy implications are drawn and discussed.

description: One of the main challenges for the manipulation and storage of multipartite entanglement is its fragility under noise. We present a simple recipe for the systematic enhancement of the resistance of multipartite entanglement against any local noise with a privileged direction in the Bloch sphere. For the case of exact local dephasing along any given basis, and for all noise strengths, our prescription grants full robustness: Even states with exponentially decaying entanglement are mapped to states whose entanglement is constant. In contrast to previous techniques resorting to complex logical-qubit encodings, such enhancement is attained simply by performing local-unitary rotations before the noise acts. The scheme is therefore highly experimentally friendly, as it brings no overhead of extra physical qubits to encode logical ones. In addition, we show that, apart from entanglement, the resiliences of the relative entropy of quantumness and the usefulness as resources for practical tasks such as metrology and nonlocality-based protocols are equivalently enhanced.

description: Skin cancer is the most common malignancy in humans. The primary treatment for skin cancer is surgery because of the excellent control rate of the malignancy. However, post-surgery complications contraindicate the use of surgical procedures on some skin cancer patients. As an alternative, radiation therapy techniques are applied to skin cancer patients. Although the current radiation therapy techniques are effective, they are listed as the most expensive treatments available for skin cancer patients. Additionally, conforming the radiation dose to the skin tumor to reduce irradiation of healthy tissue is a challenging and difficult task. To propose a solution to this challenge, a new method of radiation therapy was developed in this work. The proposed method was the use of beta-emitting isotopes as a source of radiation, and 3D printing technology as a tool to create personalized skin brachytherapy applicators and patches. Calculation and simulation data showed that most of the beta radiation dose is delivered within the very first few millimeters of tissue. This makes it a suitable radiation source for treating superficial skin tumors while sparing surrounding healthy tissue. Furthermore, these characteristics makes the shielding of this radiation less intensive than gamma and X-ray photons, reducing the treatment delivery costs. Using the 3D printed applicators and patches, it was possible to conform the radiation dose based on the 2D shape of the tumor. Because of the use of 3D printing technology in the fabrication process, the applicators were prepared in a quick and cost-effective way. In conclusion, the use of 3D printing technology in fabricating beta-emitting radiotherapeutic models seems to be able to offer an affordable and customized treatment for thin skin tumors.

Identifying secondary school teachers’ understandings and implementations of design thinking within a design-based research Approach
Creators: name: Naghshbandi, Serveh
Publisher: name: University of British Columbia
Year: 2014

description: Drawing from a Design-Based Research (DBR) approach this qualitative study examines the impact of a Maker Day Professional Development event on secondary school participant teachers’ understandings of design thinking. It also explores participants’ envisioning strategies to implement the introduced concepts. Findings generate contextual design principles for more improvement in the next iterations. Design thinking, as a human-centered approach which considers empathy supports constructionist learning and encourages students and educators to identify real-world problems and offer solutions through prototyping. By using this approach in educational settings, teachers can design learning environments, and broader sets of 21st century’s required skills can be cultivated in students. In the British Columbia’s Educational Plan teachers are being asked to move towards designing 21st century’s learning environments. To support educators in making changes to their teaching practices, the Maker Days were developed to introduce design thinking and prototyping. Within the framework of DBR, data was collected from a Maker Day through sequential phases including pre- and post-event surveys and interviews concerning to what extent the Maker Day influenced participants’ understandings of design thinking, and whether the participants envision bringing the concepts into their classrooms. Drawing from a DBR approach, data was analyzed through retrospective and cross-iteration comparisons. Findings suggest the Maker Day influenced participants’ understandings of design thinking by reinforcing the values of experiential learning, introducing human-centeredness, and improving participants’ perceptions of problem finding. Notions of iteration and refinement in a design process were identified as missed points; also, design thinking was perceived more as a making-oriented action rather than challenge-oriented process. Findings also suggest participants were not passive recipients of the knowledge. They facilitated a similar process for students, and also designed a cross-curriculum course collaboratively. However, teachers have not found an effective way to integrate design thinking with the content knowledge of specific subjects but, they are interested in moving forward with their rough ideas and trying design thinking. Findings generate contextual design principles to optimize the Maker Days. These principles provide recommendations for the decision makers, researchers, and educators to be tested and validated in other contexts.

It yields the existence of the conditional G-expectation of a Borel-measurable (rather than quasi-continuous) random variable, a generalization of the random G-expectation, and an optional sampling theorem that holds without exceptional set. Our results also shed light on the inherent limitations to constructing sublinear expectations through aggregation.

Zur Bedeutung von Cardiolipin bei der Differenzierung von Motoneuronen des Rückenmarks in vitro

description: Die Motorneurone des Rückenmarks sind zentraler Bestandteil unseres motorischen Systems. Ihre Degeneration führt zu Paresen und Paralysen der Target-Muskulatur mit anschließender Muskelatrophie. In dieser Arbeit wurde der Einfluss von Cardiolipin (CL) - das mitochondriale Signatur-Phospholipid - auf die Differenzierung von Motoneuronen untersucht. Als Studienmodell diente die Motoneuron-ähnliche Zelllinie NSC34 - eine Hybridzelllinie aus Motoneuron-angereicherten primären Rückenmarkszellen und Neuroblastomzellen. Als Differenzierungsmarker wurden verschiedene Parameter des Neuritenwachstums und der Rezeptorbesatz untersucht. Dazu kamen Aussagen zum Gehalt freier zellulärer Fettsäuren und zur Mitochondrienverteilung. Es wurde gezeigt, dass die Differenzierung von NSC34-Zellen per se stattfindet und durch den Einsatz eines Differenzierungsmediums verstärkt wird. Dabei kommt es zur Reduktion der Proliferation ohne, dass die Vitalität beeinflusst wird. Mit fortschreitender Differenzierung war eine verstärkte Abwanderung der Mitochondrien in die Filopodia zu verzeichnen. Der Gehalt der meisten CL-Spezies nahm ab; dabei gab es 2 Ausnahmen: (C18:1)2/(C16:0)2-CL und (C18:1)3/C16:0-CL. Eine lineare Regressionsanalyse zeigte eine positive Korrelation von Zelldifferenzierung (Neuritenwachstum) und den molekularen CL-Spezies, konkret den Gehalten von (C18:1)2/(C16:0)2-CL und (C18:1)3/C16:0-CL. Das daraus abgeleitete „Proof of Principle“-Experiment - Medienanreicherung mit Öl- und/oder Palmitinsäure - zeigte eine positive Beeinflussung der Differenzierungsparameter ohne die Proliferation, die Vitalität und den Cardiolipin-Haushalt wesentlich zu verändern. Somit könnte Cardiolipin ein weiteres Target für zielgerichtete Therapieansätze bei Schädigung der spinalen Motorneurone darstellen.

In particular, this gives rise to a correspondence between quasi-Einstein metrics and parallel sections of certain tractor bundles. We use this formulation to give a sharp upper bound on the dimension of the vector space of quasi-Einstein metrics, providing a different perspective on some recent results of He, Petersen and Wylie.

description: Die Adipositas ist heutzutage ein zunehmendes globales Gesundheitsproblem. Das betrifft nicht nur industrialisierte, sondern auch Schwellen- und Entwicklungsländer. Im Vergleich zur konservativen Therapie gewinnen die Adipositas- und die Metabolische Chirurgie immer mehr an Bedeutung. SG (Sleeve Gastrektomie) und RYGB (Roux-en-Y Magenbypass) sind aktuell die häufigsten Verfahren der Bariatrischen Chirurgie. Sie weisen eine sehr gute Effektivität hinsichtlich der Gewichtsreduktion auf und verbessern Komorbiditäten spürbar. Die vorliegende retrospektive monozentrische Analyse überprüft, inwiefern diese Aussagen auf super-super-adipöse Patienten mit einem BMI ≥ 60 kg/m² übertragbar sind. Die Ergebnisse der Arbeit zeigen, dass beide angewendete bariatrische Verfahren bei dieser Patientenklientel sicher und effektiv sind. Tendenziell traten im analysierten Krankengut nach RYGB etwas weniger Komplikationen auf, die Beeinflussung der Komorbiditäten war ebenfalls besser. Diese Aussage wird aber dadurch relativiert, dass die SG eher bei Patienten mit schlechterer Ausgangssituation indiziert wurde.

description: In this paper we are concerned with the simplest normal form computation of a family of Hopf-zero vector fields without a first integral. This family of vector fields are the classical normal forms of a larger family of vector fields with Hopf-Zero singularity. Indeed, these are defined such that this family would be a Lie subalgebra for the space of all classical normal form vector fields with Hopf-Zero singularity. The simplest normal forms and simplest orbital normal forms of this family with non-zero quadratic part are computed. We also obtain the simplest parametric normal form of any non-degenerate perturbation of this family within the Lie subalgebra. The symmetry group of the simplest normal forms are also discussed. This is a part of our results in decomposing the normal forms of Hopf-Zero singular systems into systems with a first integral and nonconservative systems.

description: Let $L/K$ be a finite Galois CM-extension of number fields with Galois group $G$. In an earlier paper, the author has defined a module $SKu(L/K)$ over the center of the group ring $\mathbb Z[G]$ which coincides with the Sinnott-Kurihara ideal if $G$ is abelian and, in particular, contains many Stickelberger elements. It was shown that a certain conjecture on the integrality of $SKu(L/K)$ implies the minus part of the equivariant Tamagawa number conjecture at an odd prime $p$ for an infinite class of (non-abelian) Galois CM-extensions of number fields which are at most tamely ramified above $p$, provided that Iwasawa's $μ$-invariant vanishes. Here, we prove a relevant part of this integrality conjecture which enables us to deduce the equivariant Tamagawa number conjecture from the vanishing of $μ$ for the same class of extensions. As an application we prove the non-abelian Brumer and Brumer-Stark conjecture outside the $2$-primary part for any monomial Galois extension of the rationals provided that certain $μ$-invariants vanish.

description: In der Promotionsarbeit wird das Konzept der Moufang-Mengen erklärt und einige Resultate für Moufang-Mengen bewiesen. Hauptresultat dabei ist die Lösung des sogenanntes Isomorphieproblems von Moufang-Mengen, die über Schiefkörpern definiert sind. Das Isomorphieproblem besagt dabei Folgendes: wenn zwei Moufang-Mengen (durchaus auch von unterschiedlichem Typ), die über einem Schiefkörper gegeben sind, isomorph sind, dann sind die zugrundeliegenden Schiefkörper im Regelfall ähnlich (also isomorph oder anti-isomorph). Der Beweis für alle vier in der Arbeit beschriebenen Moufang-Mengen, der Moufang-Mengen der projektiven Geraden, der Moufang-Mengen der polaren Geraden, der orthogonalen Moufang-Mengen sowie der gemischten Moufang-Mengen, benutzt dabei im Wesentlichen das Konzept von speziellen Jordan-Algebren, die in einer 1:1-Korrespondenz mit bestimmten Moufang-Mengen stehen. Dieses Resultat wird dabei in der Arbeit mitbewiesen. Weiterhin wird in der Arbeit die Eindeutigkeit von in Moufang-Mengen der polaren Geraden zugrundeliegenden Gruppen bewiesen, welche das Thema der Arbeit abschließt.
description: In this phd thesis we explain the concept of Moufang sets and prove some results on them. The main result is the solution of the so-called isomorphism problem of Moufang sets which are defined over skew fields. The isomorphism problem is stated as follows: if two Moufang sets, given over skew fields, are isomorphic, then the underlying skew fields are usually similar (which means isomorphic or anti-isomorphic). Thereby both Moufang sets may be of different type. The proof for all four Moufang sets described in the thesis, i.e. Moufang sets of the projective line, Moufang sets of the polar line, orthogonal Moufang sets and mixed Moufang sets, uses mainly the concept of special Jordan algebras. We also proof in the thesis that these special Jordan algebras have a one-to-one correspondence to some Moufang sets. Moreover we proof the uniqueness of root groups of Moufang sets of the polar line which finishes the thesis.

description: We discuss hairy black hole solutions with scalar hair of scaling dimension $Δ$ and (small) electromagnetic coupling $q^2$, near extremality. Using trial functions, we show that hair forms below a critical temperature $T_c$ in the region of parameter space $(Δ, q^2)$ above a critical line $q_c^2 (Δ)$. For $Δ> Δ_0$, the critical coupling $q_c^2$ is determined by the AdS$_2$ geometry of the horizon. For $Δ< Δ_0$, $q_c^2$ is {\em below} the value suggested by the near horizon geometry at extremality. We provide an analytic estimate of $Δ_0$ (numerically, $Δ_0 \approx 0.64$). We also compute analytically the true critical line for the entire range of the scaling dimension. In particular for $q=0$, we obtain an instability down to the unitarity bound. We perform explicit analytic calculations of $T_c$, the condensate and the conductivity. We show that the energy gap in units of $T_c$ diverges as we approach the critical line ($T_c \to 0$).

Doing communication history in sanitary systems beyond a “shell game”: a mirror comparison on silence and managerial delay practices in communicating epidemics
Creators: name: Rainero, Christian

Subjects: Covid-19, Communication, Sanitary management, Institutional silence, Epidemic.

description: This paper intends to explore the response to the Covid-19 spread under the lens of managerial perspective related to the communication practices and the probable delay provided as a strategy to avoid panic. Timeliness in health management is crucial and delay could be lethal. The research proposes an exploration on the epidemics’ response under the news titles lens and historical view based on original correspondence provided by an institutional perspective. The authors investigate the communication practices and the probable delay provided as a strategy to avoid panic or negative image repercussions. Through a synchronic and diachronic approach (news and original documents), the authors provide a comparison on communication institutional habits in the early stages of epidemics. Similarities would be present among the ancestral case of plague in 1656 and the recent Covid-19 about institutional communication response. This paper would be useful in providing a frame about lessons from the past, according to the considerations made about the actual Covid-19 pandemic spread, relating social responsible behaviours in sanitary systems and managerial delay practice in communication of the epidemic events.

description: The Haldane pseudopotential construction has been an extremely powerful concept in quantum Hall physics --- it not only gives a minimal description of the space of Hamiltonians but also suggests special model Hamiltonians (those where certain pseudopotential are set to zero) that may have exactly solvable ground states with interesting properties. The purpose of this paper is to generalize the pseudopotential construction to situations where interactions are N-body and where the particles may have internal degrees of freedom such as spin or valley index. Assuming a rotationally invariant Hamiltonian, the essence of the problem is to obtain a full basis of wavefunctions for N particles with fixed relative angular momentum L. This basis decomposes into representations of SU(n) with n the number of internal degrees of freedom. We give special attention to the case where the internal degree of freedom has n=2 states, which encompasses the important cases of spin-1/2 particles and quantum Hall bilayers. We also discuss in some detail the cases of spin-1 particles (n=3) and graphene (n=4, including two spin and two valley degrees of freedom).

La singularité partagée - Étude de cohérence empirique à travers les courbes de rotation galactique
Creators: name: Nowak, Gabriel
Publisher: name: Zenodo
Year: 2025

description: Ce document vise à tester, par des moyens mathématiques et astrophysiques, la cohérence d’une hypothèse théorique formulée dans un manuscrit précédent : celle de la Singularité Partagée — une structure géométrique universelle connectée à chaque point de l’espace-temps via un champ scalaire Φ(x^μ).

Dans ce travail, nous explorons une démarche scientifique indépendante : en intégrant un champ Φ(r) simple dans les équations gravitationnelles, nous cherchons à reproduire les courbes de rotation de galaxies spirales, sans faire appel à la matière noire. En comparant les prédictions obtenues à partir de ce champ avec les observations de NGC 3198 et NGC 2403, nous examinons si cette hypothèse produit des résultats cohérents.

L’objectif ici n’est pas de démontrer la théorie de la Singularité Partagée, mais de vérifier empiriquement si un champ Φ, inspiré de cette idée, peut expliquer certains phénomènes astrophysiques mesurables.

description: We describe a generating tree approach to the enumeration and exhaustive generation of k-nonnesting set partitions and permutations. Unlike previous work in the literature using the connections of these objects to Young tableaux and restricted lattice walks, our approach deals directly with partition and permutation diagrams. We provide explicit functional equations for the generating functions, with k as a parameter.

description: Hintergrund: Medikamenten Non-compliance ist unter herzinsuffizienten Patienten ein weltweites Problem, welches bisher in Afrika noch nicht ausreichend untersucht wurde. Entsprechend sind Daten hierzu rar. Doch gerade bei dieser Erkrankung können Patienten einen Krankenhausaufenthalt verzögern, indem sie ärztlichen Rat befolgen, also einen gesundheitsfördernden Lebensstil führen und die Medikamente entsprechend der Verordnung einnehmen. Ziele und Methoden: In dieser Studie sollte die Compliance für verschiedene Aspekte wie die Medikamenteneinnahme und des gesundheitsfördernden Lebensstils bei 200 herzinsuffizienten Patienten mittels Fragebogen (100%, n=200) und Medikamentenzählung (41%, n=82) erfasst werden, die sich in der kardiologischen Ambulanz des Chris Hani Baragwanath Krankenhaus in Soweto, Südafrika vorstellten. Ergebnisse: Das mittlere Alter der Patienten betrug 56 ± 14 Jahre, 79% der Patienten waren Schwarzafrikaner und 55% waren männlich. Die Herzinsuffizienztherapie bestand aus einem Diuretikum (93%), einem Betablocker (84%), einem ACE-Hemmer (74%), dem Aldosteronrezeptorantagonisten Spironolacton (64%) und dem Herzglykosid Digoxin (24%); durchschnittlich wurden 6 ± 2 Medikamente eingenommen. In unserer Studienpopulation wurden 71% der verordneten Medikamente korrekt eingenommen, wobei die Compliance für die einzelnen Medikamente zwischen 64% und 79% variierte. Eine große Bandbreite fand sich in der Compliance bezüglich des empfohlenen Lebensstils (2,5%-98%). Insgesamt herrschte nur geringes Wissen über die Herzinsuffizienztherapie: 56% der Patienten konnten weder Wirkungsweise noch unerwünschten Wirkungen der Medikamente benennen. Dem hingegen konnten 69% der Fragen über das Management der Herzinsuffizienz richtig beantwortet werden. Zusammenfassung: Diese Ergebnisse zeigen, dass ähnlich wie in anderen Regionen der Welt, Non-Compliance bezüglich Medikamente und einer gesundheitsfördernde Lebensweise ein wesentliches Problem in Soweto darstellt. Sie sollen als Ausgangspunkt für die Entwicklung eines „Heart Failure Management Programs“ dienen, um die Behandlung von herzinsuffizienten Patienten unter Berücksichtigung ihrer besonderen Lebensumstände in Südafrika entscheidend zu verbessern.
On a preferential attachment and generalized Pólya's urn model

description: We study a general preferential attachment and Polya's urn model. At each step a new vertex is introduced, which can be connected to at most one existing vertex. If it is disconnected, it becomes a pioneer vertex. Given that it is not disconnected, it joins an existing pioneer vertex with probability proportional to a function of the degree of that vertex. This function is allowed to be vertex-dependent, and is called the reinforcement function. We prove that there can be at most three phases in this model, depending on the behavior of the reinforcement function. Consider the set whose elements are the vertices with cardinality tending a.s. to infinity. We prove that this set either is empty, or it has exactly one element, or it contains all the pioneer vertices. Moreover, we describe the phase transition in the case where the reinforcement function is the same for all vertices. Our results are general, and in particular we are not assuming monotonicity of the reinforcement function. Finally, consider the regime where exactly one vertex has a degree diverging to infinity. We give a lower bound for the probability that a given vertex ends up being the leading one, that is, its degree diverges to infinity. Our proofs rely on a generalization of the Rubin construction given for edge-reinforced random walks, and on a Brownian motion embedding.

description: In contrast to works on victim advocacy in specific organizational contexts, this article introduces the term “victim work” to capture the vast array of victim-related roles and tasks that have proliferated in recent decades. Data are derived from in-depth interviews with 30 “victim workers” in public and private agencies in two Midwestern states. The interviews revealed diverse work experiences that spanned hotlines, crisis response, legal proceedings, and postconviction support. Three themes emerged that characterize “victim work”: flexibility, emotions, and the challenge of “fit”—the multifaceted difficulties of interacting with victims and agents of the justice system. Based on the findings, we offer a revised model of criminal justice vis-à-vis victims and implications for practice and future research.

description: Der AhR ist bekannt als Vermittler toxischer Effekte von Umweltgiften, wie zum Beispiel TCDD. Studien berichten über eine potentielle Rolle des AhR in der Physiologie des Ovars. Die Behandlung von Kumulus-Oozyten-Komplexen (KOKs) vom Rind während IVM mit dem Serin/Threoninkinaseinhibitor 6-DMAP führte zu einer Reduktion der Kernreifungsrate und der Transkription von CYP1A1 sowie der Phosphorylierung der MAP-Kinasen ERK 1 und 2. Cycloheximide inhibierte die Reifung, zeigte jedoch keinen Einfluß auf die Expression von CYP1A1. Der spezifische MAP-Kinase-Inhibitor PD98059 führte zu einer 3-stündigen Verzögerung der Aktivierung von CYP1A1 und MAPK. Dies legt eine Beteiligung von ERK 1 und 2 an der Regulation des AhR während IVM von Rinderoozyten nahe. Während IVM von KOKs vom Schwein tritt eine konstitutive Induktion von CYP1A1 auf. Exogene Liganden, in diesem Fall β-Naphthoflavone, führte über Apoptose in den Kumuluszellen zur Ovotoxizität. Bei Anwesenheit von Follikelflüssigkeit im Maturationsmedium trat keine Apotose auf.
