description: The worldwide popularity of Lois Weber’s pro-birth control, anti-abortion film Where Are My Children? (1916) prompted many in the movie industry to develop films with similar themes. Prominent among these filmmakers was Alice Guy Blaché, who approached renowned birth-control activist Rose Pastor Stokes about collaborating on such a project. The two women eventually developed a script for a film on birth control tentatively titled Shall the Parents Decide? They hoped to finish their film in time for a key event due to occur in the fall of 1916: Margaret Sanger’s opening of the first birth-control clinic in America. Shall the Parents Decide? was never made, however, and this chapter explores the reasons for its failure. The research materials include Pastor Stokes’ unfinished autobiography, Guy Blaché’s memoirs, and correspondence between the women and Guy Blaché’s representative, Bert Adler. The most important document by far is the unpublished script itself. A fifty-page typewritten affair prepared by Guy Blaché and supplemented by Pastor Stokes’ numerous hand-written emendations, the script offers a fascinating glimpse into the women’s collaborative process. It gives a clear and detailed account of the film that Guy Blaché had hoped would be, in her words, her “crowning cinema achievement.”
Women and Nationalism in Indigenous Irish Filmmaking of the Silent Period

description: Women in Ireland came into focus and onto the political stage during and as a result of nationalist and socialist movements that began in the mid-1700s and continued through the 1920s. Women like Anna Parnell, Constance Markievicz, and Hannah Sheehy-Skeffington participated in the land wars, struggles for independence from Britain and the suffragist movement. Indigenous silent feature filmmaking in Ireland was born out of this critical period of political and social change. From 1916 to 1935, Irish filmmakers produced over forty silent feature films only six of which have survived. A close study of these films, fragments of three others, and contemporary film reviews and archival synopses of the non-surviving films reveals how early Irish silent films tackled nationalist issues, but did little to represent the active participation of women. Women in these films are passive sisters, lovers, and mothers, impacted by rather than impacting historical events. This is not surprising. Irish silent cinema was a male-dominated industry with a nationalist agenda that perpetuated gender stereotypes. This study links nationalism and women in Irish silent cinema by looking at how female representation in these early films reflected a gendered ideology that existed in Irish culture alongside other narratives of the nation.

description: Ablationsbedingte Ösophagusläsionen (Endoscopically detected esophageal lesions - EDEL) sind häufige Nebeneffekte bei der Ablation des Vorhofflimmerns. Sie können im ungünstigsten Fall in eine atrio-ösophageale Fistel mit hoher Morbidität und Mortalität fortschreiten. In der vorliegenden Arbeit wurde untersucht, ob eine Vermeidung von EDEL durch die Verwendung einer Ösophagustemperatursonde (ÖTS) mit abgeschirmten Messelementen bei der Hochfrequenzstrom-Katheterablation des Vorhofflimmerns erreicht werden kann. Hierfür wurden 86 Patienten eingeschlossen, die sich einer interventionellen Ablation des Vorhofflimmerns unterzogen. Die Randomisierung erfolgte in eine Gruppe mit (Gruppe 1, n=44) oder ohne (Gruppe 2, n=42) Überwachung der intraluminalen Ösophagustemperatur (LET) mittels ÖTS. Jeder Patient wurde vor und nach dem Eingriff mittels Ösophagogastroduodenoskopie (OEGD) untersucht. Alle Patienten erhielten weiträumige antrale zirkumferentielle Ablationskreise um die ipsilateralen Pulmonalvenen (Wide Antral Circumferential Ablation - WACA). Zusätzliche Ablationen wurden in Abhängigkeit weiterer Vorhofarrhythmien bzw. Vorliegen eines arrhythmogenen Substrates (atriales Myokard mit einer Signalamplitude <0,5 mV) durchgeführt. Die Leistung an der linksatrialen Hinterwand wurde auf maximal 25 Watt begrenzt und in Gruppe 1 in Abhängigkeit der LET bis auf minimal 10 Watt titriert. In der Gruppe 1 konnten sechs EDEL (zwei Erosionen und vier oberflächliche Ulzerationen) nachgewiesen werden. In der Gruppe 2 fanden sich zwei EDEL (eine Erosion und ein tiefes Ulcus). Beide Gruppen unterschieden sich hierbei nicht signifikant. Eine ÖTS während der Vorhofflimmerablation trug nicht zur Vermeidung von EDEL bei, Patienten ohne ÖTS-Überwachung waren keinem größeren Risiko für EDEL ausgesetzt. Eine LET ≥42 °C war allerdings mit einem ca. 4-fach erhöhten relativen Risiko für EDEL verbunden (unabhängiger Risikofaktor).

description: A new physical-based electrothermal model for GaAs MESFET is presented. The 2-D electrical model based on the accurate velocity-electric field Chang-Fetterman expression is coupled to a thermal simulator which is able to take into account the thermal dependence of GaAs thermal conductivity and the multilayer structure of a typical chip. The simulator has been compared with the results of a 3-D FDM simulator and measurements. The accuracy is to be considered satisfactory and the CAD tool can easily perform the simulation on a common PC.
Application of three-body stability to globular clusters: II. Observed velocity dispersions

description: The velocity dispersion profile in globular clusters (GCs) is explained here without having to rely on dark matter or a modification of Newtonian dynamics (MOND). The flattening of the velocity dispersion at large radii in certain Milky Way GCs, or lack thereof, is explained by recourse to the stability of the three-body problem in Newtonian dynamics. The previous paper in this series determined an analytical formula for the transition radius between stable and unstable orbits for a star in a GC. This stability boundary is used here to predict where the velocity dispersion profile is expected to flatten in GCs, given known orbital parameters of the GC-galaxy orbit. Published observational data for the velocity dispersion as a function of radius of 15 Milky Way GCs with approximately known orbital parameters are used here. We find that the stability boundary predicts flattening in the majority of clusters. While observational uncertainties in the orbital parameters prevent MOND from being ruled out entirely for some clusters, it is not the preferred model in any cluster. Based on the results of this study, we recommend further velocity dispersion observations and orbital determination for NGC 6171 and NGC 6341 as these are promising candidates for distinguishing Newtonian and MOND models. In particular, NGC 6171 may already be showing evidence of the chaotic diffusion of stars leading to flattening at the predicted stability boundary.

description: TANK-binding kinase 1 (TBK1) is a key signalling component in the production of type-I interferons, which have essential antiviral activities, including against SARS-CoV-2. TBK1, and its homologue IκB kinase-ε (IKKε), can also induce pro-inflammatory responses that contribute to pathogen clearance. While initially protective, sustained engagement of type-I interferons is associated with damaging hyper-inflammation found in severe COVID-19 patients. The contribution of TBK1/IKKε signalling to these responses is unknown. Here we find that the small molecule idronoxil inhibits TBK1/IKKε signalling through destabilisation of TBK1/IKKε protein complexes. Treatment with idronoxil, or the small molecule inhibitor MRT67307, suppresses TBK1/IKKε signalling and attenuates cellular and molecular lung inflammation in SARS-CoV-2-challenged mice. Our findings additionally demonstrate that engagement of STING is not the major driver of these inflammatory responses and establish a critical role for TBK1/IKKε signalling in SARS-CoV-2 hyper-inflammation.

description: Selfheating and thermal coupling effects are the origin of the performance limitation of amplifiers with power HBTs. It is shown that an uneven tem­perature distribution in individual emitter fingers and between the fingers is responsible for the limitation. A design method is proposed, which improves the temper­ature drain and the device reliability.

description: The classical Beauville-Bogomolov Decomposition Theorem asserts that any compact Kähler manifold with numerically trivial canonical bundle admits an étale cover that decomposes into a product of a torus, and irreducible, simply-connected Calabi-Yau-- and holomorphic-symplectic manifolds. The decomposition of the simply-connected part corresponds to a decomposition of the tangent bundle into a direct sum whose summands are integrable and stable with respect to any polarisation. Building on recent extension theorems for differential forms on singular spaces, we prove an analogous decomposition theorem for the tangent sheaf of projective varieties with canonical singularities and numerically trivial canonical class. In view of recent progress in minimal model theory, this result can be seen as a first step towards a structure theory of manifolds with Kodaira dimension zero. Based on our main result, we argue that the natural building blocks for any structure theory are two classes of canonical varieties, which generalise the notions of irreducible Calabi-Yau-- and irreducible holomorphic-symplectic manifolds, respectively.

description: We analyze published data from the ALICE Collaboration in order to obtain the first extraction of the recently-proposed rapidity-even directed flow observable v1. An accounting of the correlation due to the conservation of transverse momentum restores the factorization seen by ALICE in all other Fourier harmonics and thus indicates that the remaining correlation gives a reliable measurement of directed flow. We then carry out the first viscous hydrodynamic calculation of directed flow, and show that it is less sensitive to viscosity than higher harmonics. This allows for a direct extraction of the dipole asymmetry of the initial state, providing a strict constraint on the non-equilibrium dynamics of the early-time system. A prediction is then made for v1 in Au-Au collisions at RHIC.

description: Karzinome des Larynx metastasieren spät und sind in frühen Stadien kurativ therapierbar. In der Dysplasie- und Karzinomentstehung führt die tumorinduzierte Neoangiogenese zur Entstehung charakteristisch gewundener Gefäßschleifen. Diese Arbeit stellt die Kombination aus Kontaktendoskopie und Narrow Band Imaging vor, die dazu dienen soll, diese Gefäßveränderungen früher und leichter zu erkennen. Beim Narrow Band Imaging werden über einen optischen Filter Wellenlängenspektren betont, die im Absorptionsmaximum des Hämoglobins liegen. Bei der Kontaktendoskopie berührt die Linse eines starren Endoskops die Schleimhaut, wodurch die Darstellung von mukosalen und submukosalen Strukturen möglich wird. Die Kombination beider Verfahren ermöglicht die Detailanalyse der veränderten Gefäßmuster in Läsionen der Stimmlippen. Diese Arbeit vergleicht die diagnostische Güte der Kombination aus Kontaktendoskopie und Narrow Band Imaging mit herkömmlichen Methoden. Sie zeigt, dass die Kontaktendoskopie mit Narrow Band Imaging es ermöglicht, perpendikuläre Gefäßveränderungen besser zu erkennen. So kann dieses Verfahren die Früherkennung von Larynxkarzinomen verbessern.
The influence of information exchange processes on the provision of person-centred care in residential care facilities
Creators: name: Caspar, Sienna
Publisher: name: University of British Columbia
Year: 2014

description: Purpose: The movement away from task-oriented care toward the consistent provision of person-centred care (i.e., care based on residents’ needs and preferences) is widely recognized as the goal of the residential care culture change movement. The purpose of this study was to explore why the attainment of this goal has remained elusive for many residential care facilities (RCFs), despite significant effort to alter practice. Methods: I conducted an institutional ethnography to explore the textually mediated work processes that influence the day-to-day work practices of front-line care staff in RCFs. The social organization of RCFs was explored through the observation of resident care attendants’ (RCAs') practices and the interaction of those practices with institutional texts. The data were derived from three RCFs and included 104 hours of naturalistic observation, 76 in-depth interviews, and document analysis. Results: Practical access to institutional texts containing care-related information was dependent on job classification. Regulated healthcare professionals (e.g., RNs) frequently accessed these texts to exchange information. Although RCAs provided 80% of the care to residents, in all sites studied, they lacked practical access to the institutional texts that contained important information relevant to the residents’ individualized care needs and preferences (e.g., assessments, care plans, social histories). The RCAs primarily received and shared information orally; however, the organizational systems in the facilities studied mandated the written exchange of information and did not formally support an oral exchange. Consequently, the oral exchange of care information was largely dependent upon the quality of the RCAs' working relationships with one another and especially with management. Implications: Access to detailed knowledge of residents’ needs and preferences is fundamental to the provision of person-centred care. The transfer of this knowledge to and between front-line care staff is dependent upon the quality of the relationships managers develop with and among RCAs. Initiatives aimed at building supportive and collaborative work teams are essential to the inclusion of RCAs in the care planning process and to the attainment of the goal of person-centred care.

description: Pathologies of the thoracic aorta impose themselves as a therapeutic challenge. On one hand, such pathologies must be well secured with the least possible complication; on the other hand, however, the widely varying pathological pictures and likewise anatomical variations of the thoracic aorta are implicated by therapeutic guidelines and recommendations. Hence, the choice of the best therapy is regarded with daily debates in a vascular surgeon’s routine work. This study aims to consider blockage of the left subclavian artery (LSA) as a mandate for the endovascular treatment of the pathologies of the thoracic and suprarenal abdominal aorta - this is not uncommon but scarcely contemplated in the literature- in a unicentric retrospective real-world cohort study. The patient cohort consists of those who underwent endovascular thoracic aortic reconstruction from 2006 to 2018; it contains patients who underwent either pure endovascular or hybrid endovascular/open operative therapy of different thoracic aorta pathologies. Excluded were the patients who suffered from diseases of ascending aorta and infrarenal aortic pathologies. The aim is to prove that the revascularization of LSA - in case of other intact supra-aortic arteries, especially the vertebral arteries, and the continuous circle of Willis without any right-to-left circulatory interruptions - is not necessarily required. The yearly postoperative control of the clinical status and further control-examination of the posterior cerebral/left arm circulation (Doppler-/Duplex-ultrasonography examination, comparative measurement of blood pressure) is sufficient to exclude late postoperative circulatory disturbance of the left arm as well as the cerebral circulation.
The Primordial Loop: Recursion as the Foundational Structure of Reality

description: This paper posits that the universe, existence, and the void are intrinsically recursive—self-referential phenomena whose interactions create reality as we know it. By examining recursion not as a mere mathematical or structural pattern, but as the generator of all patterns, we explore its metaphysical significance. The void itself is treated as the initial recursive success, capable of being referenced by emergent intelligence within the universe. This recursive framework offers an elegant model for understanding phenomena, observers, and even the universe’s infinite sustainability.

description: Ageing societies and the lack of professionals put strain on the care sector and lead to a care crisis. Robots can be a possible support to retain the nursing quality. However, their (future) usage comes along with various challenges such as technology acceptance or financing. To determine relevant factors of successful robot usage in nursing homes, three explorative mixed methods studies have been conducted involving different stakeholders: (I) A work analysis (HTO-Approach by Strohm & Ulich, 1997), (II) future workshops (Jungk & Müllert, 1989) and (III) expert interviews. Based on the data collected, the holistic SeRoNu-Model (Service Robots in Nursing Homes) has been created. SeRoNu is a shell model that features three layers and provides orientation for science and practice as it sums up complex aspects and derives prac-tical implications. As an exemplary validation, the model has been applied on four robot types. Nonetheless, the multifactorial scenario needs to be investigated and accompanied further on.

description: We study the basic properties of Higgs sheaves over compact Kähler manifolds and we establish some results concerning the notion of semistability; in particular, we show that any extension of semistable Higgs sheaves with equal slopes is semistable. Then, we use the flattening theorem to construct a regularization of any torsion-free Higgs sheaf and we show that it is in fact a Higgs bundle. Using this, we prove that any Hermitian metric on a regularization of a torsion-free Higgs sheaf induces an admissible structure on the Higgs sheaf. Finally, using admissible structures we proved some properties of semistable Higgs sheaves.

Extended noise theory of GaAs-schottky-diodes

Year: 1999
Subjects: ING-INF/01 Elettronica

description: An extended analysis is presented for the excess noise of GaAs-Schottky-Diodes in a mm-waveguide-mixer. A mixer simulation program includes the effects of nonlinear capacitances, arbitrary embedding impedances, non ideality of microwave diodes and all kinds of noise generated in the diode. The determination of the diode capacitance is established in an empirical way. With the measurement of both, the noise at 94 GHz and the conversion loss, it is possible to find a new characteristic of the capacitance versus voltage. This differs from the commonly used square root function. Based on measurements of the noise temperature for different currents in the frequency range of 100 MHz to 94 GHz a noise model of the diode is established and compared to conventional noise theory: In the frequency range below 2 GHz the noise temperature runs through a maximum with respect to diode current; with the frequency increased the maximum decreases and is shifted to higher currents. This effect can be modeled by a current dependent time constant in the trapping noise formula. Finally measurements at an original 94 GHz mixer were done to verify the theoretical results including the extensions mentioned above. Calculated and measured values of conversion loss and noise temperature agree in an excellent manner.

description: We construct a class of real-valued nonnegative binary functions on a set of jointly distributed random variables, which satisfy the triangle inequality and vanish at identical arguments (pseudo-quasi-metrics). These functions are useful in dealing with the problem of selective probabilistic causality encountered in behavioral sciences and in quantum physics. The problem reduces to that of ascertaining the existence of a joint distribution for a set of variables with known distributions of certain subsets of this set. Any violation of the triangle inequality or its consequences by one of our functions when applied to such a set rules out the existence of this joint distribution. We focus on an especially versatile and widely applicable pseudo-quasi-metric called an order-distance and its special case called a classification distance.

description: Abstract

This study centred on investigating the impact of revenue generation on the economic growth in Nigeria using annual time series data which covered the period of 2013 – 2022. These relationships were estimated with the autoregressive distributed lag model (ARDL) and the findings were robustly checked with the fully modified ordinary least squares (FMOLS). The findings from the ARDL results reveal that while tax revenue has a positive and significant impact on economic growth, value-added tax showed an insignificant impact, while customs and other import duties showed a significant negative influence on economic growth in Nigeria. From the FMOLS results, we found that revenue generation indicators – tax revenue, value-added tax and customs and other import duties have significant negative effects on economic growth. Improving revenue generation in Nigeria requires a multifaceted approach that encompasses tax reform, regional strategies, human capital development, and environmental sustainability initiatives. By adopting these measures, Nigeria can create a more diversified economy that not only generates sufficient revenue but also provides a solid foundation for sustainable economic growth and development. Future research should continue to explore innovative revenue generation strategies and their direct impact on Nigeria's economic landscape to guide policymakers in their efforts to build a resilient economy.

description: In dieser prospektiven Studie mit 58 Patienten konnte nachgewiesen werden, dass die Therapie mittels einer Injektion mit dem Autologes Conditioniertes Plasma (ACP) bei Patienten mit einem Impingementsyndrom (IS) der Schulter zu einer signifikanten Verbesserung der subjektiven Beschwerdesymptomatik und der Funktion führt. Zur klinischen Evaluation wurden vor und nach der Intervention in den Zeiträumen von 6-8 Wochen sowie 3 und 6 Monaten folgende Parameter erhoben: aktiver Bewegungsumfang, Constant-Score (CS), Disability of Arm, Hand and Shoulder-Score (DASH) und Simple-Shoulder-Test (SST). Die Ergebnisse wurden denen der Kontrollgruppe, welche mit einer Injektion von Lokalanästhetikum / Kortison (LA / K) behandelt wurde, gegenübergestellt. Dabei konnten 79,1 % der Patienten der ACP-Gruppe und 72,4 % der Kontrollgruppe über den gesamten Nachuntersuchungszeitraum verfolgt werden. Gegenüber der Kontrollgruppe zeigte die ACP-Gruppe vergleichbare therapeutische Effekte, wobei in Bezug auf den Parameter Kraft des CS signifikant bessere Werte in der ACP-Gruppe ermittelt werden konnten. Das in dieser Studie verwendete ACP-Depotpräparat hat gegenüber der konventionellen ACP-Injektionstherapie den Vorteil, dass nur eine einmalige Applikation in den Subacromialraum erforderlich ist. Allerdings stehen diesem Vorteil eine vermehrte Häufigkeit an temporären lokalen Schmerzreaktionen nach der Injektion gegenüber. In dieser Studie ließ sich keine Korrelation zwischen Wachstumsfaktorenkonzentrationen und Alter oder Geschlecht nachweisen. Ein für den klinischen Alltag wichtiges Ergebnis dieser Studie ist jedoch, dass die Morphologie des Acromions entsprechend der Klassifikation nach Bigliani ein Einflussfaktor auf die therapeutische Wirksamkeit der subacromialen Injektion mittels ACP oder LA / K ist. Demzufolge besteht der Hinweis, dass die hier dargestellten Injektionsbehandlungen in der konservativen Therapie des IS der Schulter nur bedingt wirksam sind, wenn der Acromiontyp III vorhanden ist.

description: We review the question of whether the fundamental laws of nature limit our ability to probe arbitrarily short distances. First, we examine what insights can be gained from thought experiments for probes of shortest distances, and summarize what can be learned from different approaches to a theory of quantum gravity. Then we discuss some models that have been developed to implement a minimal length scale in quantum mechanics and quantum field theory. These models have entered the literature as the generalized uncertainty principle or the modified dispersion relation, and have allowed the study of the effects of a minimal length scale in quantum mechanics, quantum electrodynamics, thermodynamics, black-hole physics and cosmology. Finally, we touch upon the question of ways to circumvent the manifestation of a minimal length scale in short-distance physics.

description: We study scaling properties of energy spreading in disordered strongly nonlinear Hamiltonian lattices. Such lattices consist of nonlinearly coupled local linear or nonlinear oscillators, and demonstrate a rather slow, subdiffusive spreading of initially localized wave p ackets. We use a fractional nonlinear diffusion equation as a heuristic model of this process, and confirm that the scaling predictions resulting from a self-similar solution of this equation are indeed applicable to all studied cases. We s how that the spreading in nonlinearly coupled linear oscillators slows down compared to a pure power law, while for nonlinear local oscillators a power law is valid in the whole studied range of parameters.

description: Current dynamical control based on the bang-bang control mechanism involving various types of pulse sequences is essentially a perturbative theory. This paper presents a non-perturbative dynamical control approach based on the exact stochastic Schrödinger equation. We report our findings on the pulse parameter regions in which the effective dynamical control can be exercised. The onset of the effective control zones reflects the non-perturbative feature of our approach. The non-perturbative methods offer possible new implementations when several different parameter regions are available.

Leberfett- und Lebereisenkonzentrationsbestimmung mittels multiparametrischer Magnetresonanztomografie

description: Die Fettleber ist weit verbreitet und gilt als Bestandteil des metabolische Syndroms als entscheidender Risikofaktor für koronare Herzkrankheiten und Arteriosklerose. Eine Eisenspeicherkrankheit hingegen ist selten und kann zur Herzinsuffizienz und zur Ausbildung eines hepatozellulären Karzinoms führen. Voraussetzung für eine erfolgreiche Therapie ist die frühzeitige, niederschwellige Diagnose. Die mittels quantitativer Magnetresonanztomografie (MRT) ermöglichte nichtinvasive Leberfett- und eisenkonzentrationsquantifizierung ist seit kurzem kommerziell verfügbar (Siemens LiverLab und Philips LiverHealth) und wurde in dieser Arbeit untersucht. 28 Patienten unterzogen sich Untersuchungen an 1,5T- und 3T-MRTs. Ermittelte Fettanteile und Relaxationskonstanten wurden mit histologisch und laborchemisch bestimmten Fettanteilen und Lebereisenkonzentration als Referenz korreliert. Neben den kommerziell verfügbaren Lösungen wurde Eigenimplementierung angewandt und verglichen. Die Praktikabilität im klinischen Arbeitsablauf wurde mit quantitativen Methoden geprüft. Die Ergebnisse der kommerziellen Lösungen zeigen eine hohe Übereinstimmung mit dem bioptisch ermittelten Verfettungsgrad der Hepatozyten und eine sehr hohe Übereinstimmung sowohl untereinander als auch mit der Eigenimplementierung. Das bedeutet, dass bereits klinisch verfügbare IP/OPBilder zur Ermittlung des Leberfettanteils genutzt werden können, wenn eine Siderose zuvor ausgeschlossen wurde. Die Spektroskopiemessung erwies sich nicht als zuverlässig. Die automatische Segmentierung muss sowohl in LiverLab als auch in LiverHealth in kritischen Regionen verbessert werden. LiverLab ermöglicht eine gute Integration in vorhandene Arbeitsabläufe, ist jedoch unflexibel. LiverHealth lässt sich flexibel anwenden, integriert sich allerdings schwer in den klinischen Alltag. Beide Lösungen haben das Potential, mit konsequenter Weiterentwicklung den bisherigen Goldstandard abzulösen.
On extremizing sequences for the adjoint restriction inequality on the cone

description: It is known that extremizers for the $L^2$ to $L^6$ adjoint Fourier restriction inequality on the cone in $\mathbb{R}^3$ exist. Here we show that nonnegative extremizing sequences are precompact, after the application of symmetries of the cone. If we use the knowledge of the exact form of the extremizers, as found by Carneiro, then we can show that nonnegative extremizing sequences converge, after the application of symmetries.

description: The underlying neuronal processes of the perception of time, space and other magnitudes are subject to intense scientific debate. Furthermore, mutual interactions between the perception of different dimensions are widely reported, but the origin of such crossdimensional interference effects is still not well understood. This thesis investigates time, space and numerosity judgements as well as their cross-dimensional influence on a behavioural and neuronal level within a navigational context. Participants underwent fMRI imaging while being passively moved forward along a virtual path that was covered with randomly appearing dots. After each trial, participants were asked to make judgements about the trial duration, distance covered or numerosity of items on the floor, allowing for a simultaneous observation of behavioural and neuronal effects. Behavioural results revealed a correlation between time and space judgement precision as well as a bidirectional interference only between these two dimensions, but not for numerosity. Analyses of the neuroimaging data identified the right IFG as a commonly activated area during the perception of all three dimensions and MT/V5 bilaterally as being uniquely activated during numerosity trials. Mirroring the behavioural results, activation patterns of time and space trials were indistinguishable by MVPA but could be decoded from numerosity trials, predominantly in MT/V5 as well as in the IPS bilaterally (time vs. numerosity). The findings suggest that the interference between travel time and traveled distance could be mediated by neuronal computations of movement speed on the basis of visual optic flow information. Furthermore, the results add to the body of evidence that the crossdimensional interference effects between time and space are based on overlapping neuronal representations.

description: This paper presents a modular approach for the design of MMIC lumped and transversal filter with LC tuned amplifiers. The filtering improvement due to the introduction of LC tuned amplifier modules (LCTAM) as the transversal element on the conven­tional lumped and transversal structure is illustrated by comparing the performances of a single LCTAM and double LCTAM filters with a conventional one. In order to demonstrate the novel filter usefulness three filters with two transversal sections were implemented with the same typical 0.5 um GaAs MMIC technology (a conventional, a single and a double LCTAM). It is shown that when we increase the number of LCTAM the rejection increases, however the chip area and complexity also increase. For a 1.54GHz centre fre­quency filter, a good compromise is the double LCTAM. This solution on the lower stop band (-250MHz) has 15dB more attenuation than the other two filters and on the upper stop band (+250MHz) has 17dB and 20dB more attenuation than the single LCTAM or conventional filter topology, respectively.

description: In this paper, GalnP/GaAs HBT's equivalent-circuit elements are investigated with respect to their dependence on layout geome-try. A large number of extracted parameters for HBT's of different layouts is given, as well as simple formulas, relating the element values with properties of the layout. The results are useful for large-signal modeling and layout optimization.
