description: For a given set of input-output pairs of quantum states or observables, we ask the question whether there exists a physically implementable transformation that maps each of the inputs to the corresponding output. The physical maps on quantum states are trace-preserving completely positive maps, but we also consider variants of these requirements. We generalize the definition of complete positivity to linear maps defined on arbitrary subspaces, then formulate this notion as a semidefinite program, and relate it by duality to approximative extensions of this map. This gives a characterization of the maps which can be approximated arbitrarily well as the restriction of a map that is completely positive on the whole algebra, also yielding the familiar extension theorems on operator spaces. For quantum channel extensions and extensions by probabilistic operations we obtain semidefinite characterizations, and we also elucidate the special case of Abelian in- or outputs. Finally, revisiting a theorem by Alberti and Uhlmann, we provide simpler and more widely applicable conditions for certain extension problems on qubits, and by using a semidefinite programming formulation we exhibit counterexamples to seemingly reasonable but false generalizations of the Alberti-Uhlmann theorem.

Configuration of multiple input multiple output antenna arrays for wireless communications in underground mines
Creators: name: Emami Forooshani, Arghavan
Publisher: name: University of British Columbia
Year: 2013

description: In recent years, the underground mining community has begun to embrace standards-based short-range wireless communications technology as a key part of their strategy for enhancing the safety and productivity of their operations. Here, we show how the significant differences between wireless propagation in conventional surface environments and underground mines affect the design of modern wireless communications systems based upon multiple-input multiple-output (MIMO) antenna array technology. In order to achieve this goal, we have employed a variety of approaches to characterize wireless propagation (and MIMO-based wireless system performance) in underground environments representative of those found in modern hard rock mines, including: 1) field measurements collected using a custom-designed channel sounder in both a building service tunnel at the University of British Columbia and an underground lead-zinc mine at Myra Falls, BC, 2) simulations based upon ray-tracing in representative environments and 3) theoretical models based upon waveguide mode expansion in representative environments. We have used the results obtained: 1) to determine the reduction in the angular spread of multipath signals that arrive at the receiver in an underground mine compared to that observed in conventional surface environments and the manner in which it decreases with increasing transmitter-receiver separation and 2) to show that the antenna elements in MIMO antenna arrays used in underground environments must therefore be separated by several wavelengths (rather than the customary half-wavelength used in surface environments) in order to achieve acceptable performance. Further, the separation between the antennas must increase as the transmitter-receiver separation increases, higher order modes attenuate and, as a consequence, angular spread decreases. Other outcomes of this work include: 1) demonstration that the power azimuth spectrum (PAS) in underground mine environments can be modeled by a Gaussian distribution and 2) development of a novel technique based upon particle swarm optimization (PSO) for assessing and optimizing the performance of distributed-MIMO antenna systems in underground mine environments.

description: Context Venous thrombosis has been described in patients with acute and chronic pancreatitis. This is especially common in portal vein, splenic vein and superior mesenteric vein. To the best of our knowledge, involvement of superior vena cava and subclavian vessel due to pancreatitis has not been reported. Case report We present here a case of an adult male with alcoholic chronic pancreatitis who presented with multiple vessel thromboses involving superior vena cava, inferior vena cava, bilateral subclavian, internal jugular vein, axillary, iliac and renal vein without involvement of portal, splenic and superior mesenteric vein that was effectively treated with i.v. anticoagulation therapy. Conclusion Venous thromboses can occur outside the splanchnic circulation in pancreatitis.

description: In the present paper, we consider nonlinear PT-symmetric dimers and trimers (more generally, oligomers) embedded within a linear Schr{ö}dinger lattice. We examine the stationary states of such chains in the form of plane waves, and analytically compute their reflection and transmission coefficients through the nonlinear PT symmetric oligomer, as well as the corresponding rectification factors which clearly illustrate the asymmetry between left and right propagation in such systems. We examine not only the existence but also the dynamical stability of the plane wave states and interestingly find them to be generically unstable. Lastly, we generalize our numerical considerations to the more physically relevant case of Gaussian initial wavepackets and confirm that the asymmetry in the transmission properties persists in the case of such wavepackets, as well.

description: Stochastic methods are ubiquitous to a variety of fields, ranging from Physics to Economy and Mathematics. In many cases, in the investigation of natural processes, stochasticity arises every time one considers the dynamics of a system in contact with a somehow bigger system, an environment, that is considered in thermal equilibrium. Any small fluctuation of the environment has some random effect on the system. In Physics, stochastic methods have been applied to the investigation of phase transitions, thermal and electrical noise, thermal relaxation, quantum information, Brownian motion etc. In this review, we will focus on the so-called stochastic Schrödinger equation. This is useful as a starting point to investigate the dynamics of open quantum systems capable of exchanging energy and momentum with an external environment. We discuss in some details the general derivation of a stochastic Schrödinger equation and some of its recent applications to spin thermal transport, thermal relaxation, and Bose-Einstein condensation. We thoroughly discuss the advantages of this formalism with respect to the more common approach in terms of the reduced density matrix. The applications discussed here constitute only a few examples of a much wider range of applicability.

 Robustochelia robusta: Kudinova-Pasternak, 1983: 1171. JóŸwiak & B³a¿ewicz-Paszkowycz, 2007: 27–31, figs 4–6.
 Remarks. The genus Robustochelia was placed in the subfamily Akanthophoreinae by Sieg (1986a) but was subsequently removed to the incertae cedis category by Larsen & Wilson (2002). A generic diagnosis was also given by Larsen (2005), with four known species. A very recent paper by Jóżwiak, & BłaŻewicz-Paszkowyc (2007) has updated the taxonomy, redescribed the type species R. robusta, added a further new species and removed R. solida Larsen (2005) from the genus. The cheliped and pereopod morphology, and shape of the mandibular molar (and other mouthparts) suggest a close relationship with Leptognathioides (see above) and Monstrotanais Kudinova-Pasternak.
 The species Robustochelia robusta was originally described from material collected from the Kurile- Kamchatka Trench at 4945–5240 metres (Kudinova-Pasternak 1970), but has not been recorded in the present study. It is also reported from the more southerly Izu-Ogasawara Trench, 6770–6850m (Kudinova-Pasternak 1977) and doubtfully from the south Atlantic, at 2600 metres (Kudinova-Pasternak 1975).

description: We study the observational signature of vector metric perturbations through the effect of weak gravitational lensing. In the presence of vector perturbations, the non-vanishing signals for B-mode cosmic shear and curl-mode deflection angle, which have never appeared in the case of scalar metric perturbations, naturally arise. Solving the geodesic and geodesic deviation equations, we drive the full-sky formulas for angular power spectra of weak lensing signals, and give the explicit expressions for E-/B-mode cosmic shear and gradient-/curl-mode deflection angle. As a possible source for seeding vector perturbations, we then consider a cosmic string network, and discuss its detectability from upcoming weak lensing and CMB measurements. Based on the formulas and a simple model for cosmic string network, we calculate the angular power spectra and expected signal-to-noise ratios for the B-mode cosmic shear and curl-mode deflection angle. We find that the weak lensing signals are enhanced for a smaller intercommuting probability of the string network, $P$, and they are potentially detectable from the upcoming cosmic shear and CMB lensing observations. For $P\sim 10^{-1}$, the minimum detectable tension of the cosmic string will be down to $Gμ\sim 5\times 10^{-8}$. With a theoretically inferred smallest value $P\sim 10^{-3}$, we could even detect the string with $Gμ\sim 5\times 10^{-10}$.

description: Trotz vielfältiger Argumente zur vermehrten Umsetzung fächerübergreifenden Unterrichts und diverser Publikationen zu Unterrichtkonzepten in verschiedensten fächerkombinationen werden viele Barrieren wie zeitliche Ressourcen oder habituelle Bedenken kommuniziert, die einer Umsetzung im Wege stehen. Ursächlich scheinen vor allem die Vorprägung der Lehrkräfte durch ihre eigene Schulzeit und die weiterhin fachlich orientierte Ausbildung an der Universität zu sein. Demnach sollten die fachlichen Strukturen bereits in der Lehramtsausbildung aufgebrochen werden, um Lehramtsstudierende für die Durchführung fächerübergreifenden Unterrichts zu sensibilisieren. Zur Planung und Umsetzung fächerübergreifenden Unterrichts bieten sich vor allem Praktika wie die Berufsfeldbezogene Praxisstudie (BPSt) an. An der Universität Bielefeld wurde in diesem Kontext ein Seminarformat entwickelt, welches die kommunizierten Barrieren durch eine theoretische, konzeptionelle und praktische Vermittlung adressiert. Im Zentrum steht eine Planungshilfe (in Anlehnung an Caviola et al., 2011), die eine übersichtliche und strukturierte Grobplanung fächerübergreifender Konzepte zulässt und für jegliche Fächerkombination eingesetzt werden kann. Neben dem Einsatz in der Lehrerausbildung ist eine Schulung bereits ausgebildeter Lehrkräfte über Fortbildungskonzepte ebenso möglich.

description: Etwa drei Millionen Kinder in Deutschland leben derzeit in Armut, die sich in vielfältiger Weise auf ihr Leben niederschlagen und die materielle, kulturelle, soziale, physische und psychische Versorgung beeinflussen kann. Armut kann sich auch auf den Sportunterricht auswirken, da beispielsweise bereits das außerschulische Sportengagement von sozialer Ungleichheit geprägt wird und zu unterschiedlichen Eingangsvoraussetzungen führt. Daher ist es wichtig, dass Sportlehrkräfte sich mit der Armutsproblematik auseinandersetzen, um durch die Förderung motorischer, sozialer und motivationaler Fähigkeiten den von Armut betroffenen Kindern eine gleichberechtigte Teilhabe am Sportunterricht ermöglichen zu können. Der vorliegende Beitrag setzt hier an und stellt eine Lehreinheit von zwei Seminarsitzungen für die universitäre Lehre vor. Diese Lehreinheit verfolgt mithilfe des Ansatzes der reflexiven Inklusion nach Budde und Hummrich (2013) das Ziel, angehende Sportlehrkräfte für Armut und die damit verbundene Lebenswirklichkeit von Schüler*innen zu sensibilisieren.

description: Die hier vorgestellte Methode des Sokratischen Gesprächs soll als eine ergänzende Möglichkeit der universitären Lehre dargestellt werden. Sie hebt sich von Vorlesungen, Seminaren, Kolloquien etc. dadurch ab, dass der*die Dozent*in als Leiter*in des Sokratischen Gesprächs keine inhaltliche Ausgestaltung vornimmt. In seinem Mittelpunkt stehen philosophische Themen und Fragen, die „nur mit dem Instrument des Reflektierens über Erfahrungen, die allen Gesprächsteilnehmern (!) zur Verfügung stehen“ (Heckmann, 2018, S. 21), erarbeitet werden können. Solche philosophischen Themen können Fragen zu Ethik und Wissenschaftstheorie, Grundfragen zu Politik und Erziehung sowie Fragen zur Struktur unserer inneren Erfahrung sein. Ziel des Artikels ist erstens, ein Konzept für die konkrete Durchführung des Sokratischen Gesprächs in Universität und Hochschule vorzustellen, um dann zweitens zu begründen, unter welchen Voraussetzungen das Sokratische Gespräch eine wichtige und sinnvolle Ergänzung des universitären bzw. hochschulischen Curriculums darstellen kann.

description: Purpose This study was undertaken to analyze the quality of life changes reported by patients with pancreatic cancer undergoing pancreatectomy. Design Post-hoc analysis was performed of a clinical trial examining the safety of intraoperative autotransfusion during oncologic resections. Main outcome measures Perioperative (90-day) complications were graded prospectively using a validated 5-point scale. Quality of life parameters were recorded prospectively by a single trained interviewer preoperatively, at the first post-operative outpatient visit, and at 6 weeks, 3 months, and 6 months follow-up using the EORTC QLQ-C30 and FACT-An instruments. Results Pancreatectomy for adenocarcinoma was performed in 34 patients with a median follow-up of 2 years (range: 1-1.5 years). Major (grade ≥ 3) complications occurred in 12 (35.3%) of patients. Early (<6 month) recurrence was noted in 2 patients (5.9%). Increased severity of fatigue, pain, dyspnea, and loss of appetite over baseline were noted at initial follow-up (P<0.05); however, symptom scores normalized at 6-week follow-up, and remained stable at 6 months. No significant difference was noted in quality of life metrics between patients with or without major complications (P>0.11). A significant (P=0.023) decline in cognitive function vs. baseline was noted at 6-month follow-up after pancreatectomy. Using a repeated-measures generalized linear model, neither age, nor complication occurrence, nor adjuvant therapy, nor early recurrence accounted for this cognitive decline (P>0.10). Conclusion Quality of life metrics tend to normalize to preoperative levels after pancreatectomy at 6 weeks post-operatively. The occurrence of major complications does not predict a decreased quality of life. The decrease in self-reported cognitive function at six months in this cohort merits further study.

Under very mild conditions, we find integral formulae for the tail distribution P(τ_x > t) of first passage times τ_x through a barrier at x > 0, and its derivatives in t. As a corollary, we examine the asymptotic behaviour of P(τ_x > t) and its t-derivatives, either as t goes to infinity or x goes to 0.

description: In Materialwerkstätten diskutieren Lehrende anhand von konkretem Lehrmaterial über Lehre in der Lehrer*innenbildung und entwickeln das Lehrmaterial weiter. Dabei folgt das konzipierte Reflexionsformat einer spezifischen Struktur, die sich in unterschiedliche Phasen gliedert. Um Personen zu unterstützen, die Interesse an der Durchführung von Materialwerkstätten haben, fokussiert der vorliegende Beitrag die Moderation von Materialwerkstatt-Sitzungen. Dafür werden zunächst der Ablauf einer Sitzung und die Funktion der Moderation erläutert. Als Material sind dem Beitrag neben einem Video zur Erläuterung des Sitzungsablaufs Impulsfragen für die Moderation der Diskussionsphasen beigefügt. Auf der Grundlage empirischer Untersuchungen von Materialwerkstätten geben die Impulsfragen einen Überblick darüber, worüber Lehrende bei der Auseinandersetzung mit hochschulischen Lehrmaterialien der Lehrer*innenbildung diskutieren, und können moderierenden Personen somit als Orientierung dienen. Im Rahmen der Erläuterung des theoretischen Hintergrunds wird im Beitrag auf das Reflexionsverständnis in Materialwerkstätten sowie drei Grundzüge bei der Moderation von Diskussionen eingegangen. Diese Ausführungen sollen als Hintergrundwissen bei der Ausgestaltung der eigenen Moderationsrolle helfen. Erfahrungen zu möglichen Herausforderungen bei der Moderation von Materialwerkstätten schließen den Beitrag ab.

description: Stop squarks with a mass just above the top's and which decay to a nearly massless LSP are difficult to probe because of the large SM di-top background. Here we discuss search strategies which could be used to set more stringent bounds in this difficult region. In particular, we note that both the rapidity difference Delta y(t,tbar) and spin correlations (inferred from, for example, Delta phi(l+,l-)) are sensitive to the presence of stops. We emphasize that systematic uncertainties in top quark production can confound analyses looking for stops, making theoretical and experimental progress on the understanding of Standard Model top production at high precision a very important task. We estimate that spin correlation alone, which is relatively robust against such systematic uncertainties, can exclude a 200 GeV stop at 95% confidence with 20 fb^-1 at the 8 TeV LHC.

Apart from numerous records from other areas in the Pacific and Atlantic (but see above) this species has been recorded from the Sea of Japan at shelf to bathyal depths, 100–2220 metres (Kudinova-Pasternak 1984) and abyssal depths, 3385–4895 metres from the Kurile-Kamchatka Trench (Kudinova-Pasternak 1970). The most likely candidate species for the shallow-water records is the recently described C. hansknechti, while the abyssal records may be attributable to either of the two putative species outlined below.

description: Context The surgical management of pancreatic endocrine tumors in patients with multiple endocrine neoplasia type 1 (MEN-1) is controversial and complicated by the fact that these tumors are frequently multifocal. The degree of tumor resection is determined by weighing the risk of malignancy or tumor recurrence against the risks of endocrine/exocrine insufficiency with complete gland removal. Methods A retrospective review was performed identifying 4 patients with MEN-1 and pancreatic endocrine tumors treated with pancreatic resection over a 2-year period at our institution. Results Mean age at operation was 35 years. Surgical approach was determined by size of tumor(s) and presence of multifocality. MRI and EUS were performed in all patients. While EUS identified a greater number of tumors when compared to MRI (median 5 versus 1), both studies grossly underestimated the total number of tumors found on final pathology. Three patients underwent laparoscopic total pancreatectomy for multifocal disease with diffuse pancreatic involvement, finding a median of 12 tumors. One patient underwent laparoscopic subtotal pancreatectomy for a presumed single pancreatic tail mass, but was found to have multifocal disease on final pathology consisting of 7 tumors. The average number of tumors found on final pathology was 13.5 with an average size of 2.6 cm. The median number of lymph nodes analyzed was 14. Diffuse, multifocal disease was present in all 4 patients. No major postoperative complications were observed. Conclusion In patients with MEN-1 and pancreatic endocrine tumors, preoperative workup underestimates extent of disease and total pancreatectomy should be considered for complete tumor removal.

description: Context Cyst fluid CEA concentration >192ng/mL has proven accurate to differentiate mucinous from non-mucinous pancreatic cystic neoplasms. It is unclear whether the degree of cyst fluid CEA elevation is predictive of malignant behavior in IPMNs. Objectives To determine whether elevated cyst fluid CEA concentrations were predictive of invasive cancer. Design Cross sectional study. Setting Single National Cancer Institute comprehensive cancer care center experience. Patients Forty-seven patients underwent preoperative EUS-FNA with cyst fluid analysis and surgical resection of an IPMN over a 9 year period. Main outcome measurements Cyst fluid CEA concentrations among the four grades associated with IPMN (low grade dysplasia, moderate dysplasia, high grade dysplasia, and invasive cancer). Results The mean±standard deviation cyst fluid CEA concentration increased as the pathology progressed from low grade dysplasia (1,261±1,679 ng/mL) to moderate dysplasia (7,171±22,210 ng/mL) to high grade dysplasia (10,807±36,203 ng/mL). However, the mean CEA level decreased (462±631 ng/mL) once invasive cancer developed (P=0.869). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of a cyst fluid CEA concentration greater than 200 ng/mL for the diagnosis of malignant IPMN (cases of high grade dysplasia and invasive IPMN) was 52.4%, 42.3%, 42.3%, 52.4% and 46.8%, respectively. Limitations Single center experience, small patient numbers, retrospective data collection. Conclusion The degree of cyst fluid CEA elevation is a poor predictor of malignant degeneration within IPMNs. Clinical management decisions regarding surgical resection should not be based upon degree of cyst fluid CEA elevation.

Introducing the Slotheon: a slow Galileon scalar field in curved space-time

description: In this paper we define covariant Galilean transformations in curved spacetime and find all scalar field theories invariant under this symmetry. The Slotheon is a Galilean invariant scalar field with a modified propagator such that, whenever gravity is turned on and energy conditions are not violated, it moves "slower" than in the canonical set-up. This property is achieved by a non-minimal derivative coupling of the Slotheon to the Einstein tensor. We prove that spherically symmetric black holes cannot have Slotheonic hairs. We then notice that in small derivative regimes the theory has an asymptotic local shift symmetry whenever the non-canonical coupling dominates over the canonical one.

Hover - a music theatre work in three acts
Creators: name: Roark, Timothy Benton
Publisher: name: University of British Columbia
Year: 2013

description: Hover is an experimental music theatre work for seven singers (mezzo-soprano, tenor, baritone, soprano, alto, tenor, bass) and a quintet consisting of Bb clarinet (doubling on bass clarinet), electric guitar (doubling on classical guitar), percussion (vibraphone, glockenspiel, suspended cymbals, high-hat, triangle, tamtam, snare, toms, and bass drum), viola (doubling on violin), and double bass. It is approximately 90 minutes in duration. Act I is approximately 40 minutes and is comprised of four scenes; Act II is approximately 30 minutes and is comprised of two scenes; Act III is approximately 20 minutes and is comprised of three scenes. An intermission is possible between Acts I and II. Hover is the story of one woman – The Dreamer – and her attempt to come to terms with a traumatic event that happened one year ago – an accidental waking during surgery. In a flashback memory of the event, she dreams she meets two important men from two different centuries – The Traveler and The Diver – who have also experienced moments where their bodies have performed seemingly impossible feats. All three face profound skepticism in the telling of their own stories and in trying to cope begin to dismantle cultural myths to prove that their personal stories are true and hold weight. The music of Hover supports this action by assimilating many styles, melodic motives, harmonic devices, and textural approaches into one language that reflects the multifaceted nature of the narrative.

description: Context Optimal diagnostic and treatment modalities in chronic pancreatitis are controversial due to lack of evidence. Objective To evaluate current clinical practice, we conducted a survey with the primary objective to evaluate decisions regarding the diagnosis, management and screening in chronic pancreatitis. Design We developed a vignette survey. Setting We surveyed Dutch gastroenterologists, internists, gastrointestinal surgeons and an international expert panel. Results A total of 110 questionnaires (31% gastroenterologists, 39% internists and 20% gastrointestinal surgeons) were returned out of the 1,324 sent (response 8.3%). There was a wide variation in strategies regarding diagnosis, treatment and screening in chronic pancreatitis. As a diagnostic test, serum amylase is used frequently by internists, while gastroenterologists and experts often use fecal elastase. Most respondents preferred CT-scanning for diagnosis, while experts preferred transabdominal ultrasonography as an initial test. Respondents frequently use pancreatic enzymes for treatment of pain in chronic pancreatitis. The majority advised to perform an intervention (endoscopic or surgical) in case of morphological changes of the pancreatic duct. Conclusions The results of our survey identify important differences between physicians in diagnosis and management of chronic pancreatitis. This is often due to lack of evidence and consensus in literature. Certain wide-spread practices are in contrast with available evidence, and should be addressed by improved education and adherence to guidelines.

 Remarks. A very charismatic and distinctive abyssal species, which has been linked to a possible symbiotic relationship with holothurians such as Amperima rosea, Deima validum and Oneirophanta mutabilis (Thurston et al 1987). Formerly part of the Family Leptognathiidae sensu Sieg, 1973, and latterly in the sub-family Leptognathiinae (Anarthruridae) it was excluded after a phylogenetic analysis (Larsen & Wilson 2002).
 It is widely distributed in the world’s oceans (Thurston et al. 1987) including the Kurile-Kamchatka Trench, 2400–4829 metres (Kudinova-Pasternak 1970) but has not been recorded in the present study.

description: Omni-directional light coupling to surface plasmon polariton (SPP) modes to make use of plasmon mediated near-field enhancement is challenging. We report possibility of near dispersion-less modes in structures with unpatterned metal-dielectric interfaces having 2-D dielectric patterns on top. We show that the position and dispersion of the excited modes can be controlled by the excitation geometry and the 2-D pattern. The anti-crossings resulting from the in-plane coupling of different SPP modes are also shown.

description: In diesem Beitrag skizzieren wir einen Vorschlag für eine fachdidaktische Adaption der ethnographischen Beobachtung. Ausgehend von einer fachspezifischen Gestaltung Forschenden Lernens – hier am Beispiel des Faches Deutsch – soll gezeigt werden, wie eine „fachdidaktisch inspirierte Ethnographie“ im Kontext studentischer Praxisphasen im Lehramtsstudium eingesetzt werden kann, um für die fachliche Mikrostruktur und die inhärenten Mechanismen des Deutschunterrichts an der Grundschule zu sensibilisieren. Insbesondere die Vermittlung und Schulung einer wissenschaftlichen Wahrnehmung in Anlehnung an das Konzept von Goodwin (1994) „Professional Vision“, speziell bezogen auf fachdidaktische Inhalte, soll durch das vorgestellte Seminarkonzept ermöglicht werden. Dazu werden im Beitrag zunächst zentrale theoretische Bezüge aus Kasuistik, Vignettenforschung und Forschendem Lernen skizziert, um darauf aufbauend die Notwendigkeit zur Schulung einer professionellen (Unterrichts-)Wahrnehmung darzustellen. Im Beitrag wird das Seminarkonzept detailliert erläutert. Die darin genannten Begleitmaterialien werden zur Nachnutzung zur Verfügung gestellt.
