subject: 617

description: Hintergrund: Das intraoperative Neuromonitoring (ION) des N. laryngeus recurrens (NLR) hat sich bei Schilddrüsenoperationen im Sinne einer routinemäßigen Anwendung durchgesetzt. Aus der Literatur bekannt ist die eingeschränkte Validität des ION, so dass eine sichere Vorhersage über die postoperative Stimmlippenfunktion nicht möglich ist. Ziel der Arbeit war es, die Validität des ION und die Validität in Abhängigkeit vom Eingriffsausmaß zu überprüfen. Es sollten Ursachen für die eingeschränkte Aussagekraft ermittelt werden, um durch entsprechende Schlussfolgerungen die Interpretation und die klinische Wertigkeit des ION zu verbessern. Material und Methode: Im Zeitraum 3/98-12/03 wurden bei allen Operationen mit Einsatz des ION die Daten über die prä- und postoperative Stimmlippenfunktion und über das ION gesammelt. Anhand der Daten von 3482 nerves at risk wurde die Validität des ION, die Validität in Abhängigkeit vom Eingriffsausmaß und die Ursachen für das Auftreten von Divergenzen zwischen ION und postoperativer Stimmlippenfunktion untersucht. Ergebnisse: Es zeigte sich eine niedrige Sensitivität und ein niedriger positiver Vorhersagewert bei hoher Spezifität und hohem negativen Vorhersagewert. Die Validität ist bei geringerem Eingriffsausmaß besser als bei ausgedehnteren Eingriffen. Die Validität ist bei Primäreingriffen bei benignen Schilddrüseneingriffen besser als bei Wiederholungseingriffen und besser als bei Eingriffen bei Schilddrüsenmalignom. Vor allem beim negativen Vorhersagewert bestehen signifikante Unterschiede. Die bei der Einzelfalluntersuchung gewonnenen Detailinformationen decken Pitfalls auf, anhand derer Empfehlungen für die Anwendung des ION gegeben werden können. So ist die standardisierte Ableitung der Signale vom NLR und vom N. vagus vor und nach aller operativer Maßnahmen und deren Dokumentation zu fordern. Zur besseren Interpretation ist die Objektivierung des ION-Signals mittels Aufzeichnung und Auswertung der EMG-Kurven zu empfehlen.

An empirical and economic analysis of high school peer effects
Creators: name: Hill, Andrew J.
Publisher: name: University of British Columbia
Year: 2013

description: Parents are concerned about the influence of friends during adolescence. Using the gender composition of schoolmates in an individual's close neighbourhood as an instrument for the gender composition of an individual's self-reported friendship network, Chapter 2 of this dissertation finds that the share of opposite gender friends has a sizeable negative effect on high school GPA. The effect is found across all subjects for students over the age of sixteen, but is limited to mathematics and science for younger students. Self-reported difficulties getting along with the teacher and paying attention in class are important mechanisms through which the effect operates. The subject-specific effects for younger students and larger estimates for females in general are consistent with a gender socialization hypothesis in which young females conform to traditional gender roles in the presence of males. Chapter 3 investigates the extent to which course repeaters in high school mathematics courses exert negative externalities on their course-mates. Using individual and school-specific course fixed effects to control for ability and course selection, it shows that doubling the number of repeaters in a given course (holding the number of course-takers constant) results in a 0.15 reduction in GPA scores for first-time course-takers. Further results suggest that the negative effect is only evident when the share of repeaters reaches a threshold of five to ten percent of the total number of course-takers. Chapter 4 provides evidence that part-time work during high school affects the college attendance and labour market entry decisions of young adults: 8-10th grade students working more than five hours per week are less likely to attend college and more likely to enter the labour market upon high school graduation than other students. The part-time working behaviour of same-grade schoolmates is used as an instrument for individual part-time working behaviour.

description: Coupled mode theory (CM) is widely applied in integrated optics, while the rigorous Local Mode theory (LM) is less known, being somewhat harder to implement. We compare the two theories in determining polarization coupling inside a laminated rib waveguide made of a-Si:H and SiO2.For moderate optical axis slant (low hybridization) and for fixed layer thickness the two theories show similar results but LM becomes mandatory when hybridization is important.

description: We consider energetics and structural properties of a many particle system in one dimension with pairwise contact interactions confined in a parabolic external potential. To render the problem analytically solvable, we use the harmonic approximation scheme at the level of the Hamiltonian. We investigate the scaling with particle number of the ground state energies for systems consisting of identical bosons or fermions. We then proceed to focus on bosonic systems and make a detailed comparison to known exact results in the absence of the parabolic external trap for three-body systems. We also consider the thermodynamics of the harmonic model which turns out to be similar for bosons and fermions due to the lack of degeneracy in one dimension.

description: Es gibt in der Literatur sowohl klinische als auch theoretische Daten, die einen Zusammenhang zwischen pulmonalen Erkrankungen und dem Gerinnungssystem wahrscheinlich erscheinen lassen. Von zentraler Bedeutung ist hierbei die Funktion der Vaskulären Endothelzelle. Aus diesem Grund untersuchten wir ausgewählte Parameter der Hämostase und Fibrinolyse im peripheren Blut von 174 Patienten mit Lungenerkrankungen und 39 gesunden Probanden. Wir konnten in allen Patientengruppen eine signifikante Gerinnungsaktivierung mittels zwei verschiedener Laborparameter (TAT und F 1+2) nachweisen und zeigen, daß es bei den Patienten mit Thrombinaktivierung gehäuft zum Nachweis vermehrter intravaskulärer Fibrinbildung kommt. In der Patientengruppe mit allergischem Asthma bronchiale ist die Thrombinaktivierung geringerer ausgeprägt als in allen anderen Krankheitsgruppen. Die Ursache dessen ist unklar, und auch nicht durch Literatur belegbar. Der Nachweis des Zusammenhanges zwischen Entzündung und Gerinnungsaktivierung, insbesondere der Nachweis der Aktivierung des Intrinsic System der plasmatischen Gerinnung gelang nicht. Die pathophysiologische oder prognostische Bedeutung dieser Resultate muß durch weitere Untersuchungen erhärtet werden. Ein Benefit oraler Antikoagulation einer ausgewählten Patientengruppe mit TA ist denkbar und mit Daten aus der Literatur belegt.
description: Introduction: An altered clotting or fibrinolytic system is shown to have prognostic relevance not only in vascular and coronary artery disease but in small cell lung cancer too. The close linkage between inflammation vascular damage and haemostasis led to the hypothesis that an altered clotting system can bee associated with chronic pulmonary disease. Patients and Method: Peripheral blood plasma of 174 patients (Asthma, COPD, Sarcoidosis, IPF, Cystic Fibrosis and Pulmonary Emboly) and 39 healthy controls was analysed concerning the concentration of Thrombin-Antithrombin III-Complex (TAT), Prothrombinfragments F 1+2 (F 1+2), D-Dimeres, activated Factor XII (F XIIa) and the activity of Plasminogen-Activator-Inhibitor 1(PAI). Results: A significant clotting activation could be detected in all patient groups compared to the controls. There was no association between Factor XII activation or decreased fibrinolytic activity and clotting activation detectable. Conclusion: Clotting activation is associated with non-malignant pulmonary disease. Underlying pathomechanisms such as Intrinsic System activation or association between inflammation and haemostasis could not be discovered.
The role of lysosomal acid lipase in regulation of the ATP-binding cassette transporter A1, high density lipoprotein and reverse cholesterol transport
Creators: name: Bowden, Kristin Louise
Publisher: name: University of British Columbia
Year: 2013

description: The key regulator of initial HDL particle formation by cells is the ATP-binding cassette transporter A1 (ABCA1). ABCA1 expression is regulated primarily by oxysterol dependent activation of the liver X receptor (LXR). We investigated the role of lysosomal cholesterol on ABCA1 regulation by studying the lysosomal disorder Cholesteryl Ester Storage Disease (CESD). CESD is caused by genetic mutations in the LIP-A gene that result in only 5% of normal activity of lysosomal acid lipase (LAL), an enzyme that hydrolyzes cholesteryl esters (CE) and triglycerides on internalized lipoproteins specifically within the lysosome. We hypothesized that the flux of unesterified cholesterol out of the lysosomes from LAL-mediated hydrolysis of LDL cholesteryl esters is a key regulator of cellular ABCA1 expression, HDL formation and reverse cholesterol transport (RCT). We found that primary skin fibroblasts derived from individuals with CESD had impaired upregulation of ABCA1 in response to LDL loading, reduced phospholipid and cholesterol efflux to apoA-I, lower production of 27-hydroxycholesterol (27-OH) production in response to LDL loading and reduced α-HDL particle formation. This defect was recapitulated in normal fibroblasts following treatment with LAL inhibitors, whereas, treatment with conditioned medium from normal fibroblasts containing secreted LAL rescued ABCA1 expression, apoA-I-mediated cholesterol efflux, HDL particle formation and production of 27-OH by CESD cells. We further investigated the role of LAL in RCT from macrophages specifically using an immortalized macrophage cell line created from LAL-deficient mouse peritoneal macrophages (LAL-/-). LAL-/- macrophages exhibited reduced basal and cholesterol-stimulated ABCA1 expression in culture, and reduced ability to support RCT in LAL-/- mice compared to wild-type (LAL⁺/⁺) macrophages injected into LAL⁺/⁺ mice. ABCA1 protein expression was reduced in LAL-/- mouse liver and mRNA expression of several LXR-dependent genes involved in reverse cholesterol transport (ABCG1, ABCG5, ABCG8, CYP7A1, SR-B1) were differentially modulated compared to LAL⁺/⁺ controls. These results indicate a critical role of LAL in promoting lysosomal flux of cholesterol for ABCA1 expression, cellular cholesterol efflux and RCT in vivo.

description: This paper shows the results of research on the optical control of a GaAs chip monolithic amplifier,and is an extension of previous work by our group in the field of optical-microwave interaction [1-3 ].The amplifier was originally designed for the transmitter stage of an indoor mobile communications system in the 2.4 GHz band.The possibilities of optical control of this amplifier are evidenced as follows:if the amplifier operates with the same biasing, the gain can be optically controlled from a condition of almost isolation,(small signal gain less than -5 dB),up to an active condition,(small signal gain greater than 10 dB), which gives a range of optical control of about 15 dB.At the same time,the optical control provides an improvement of the input and output matching in a range of 12dB and 6dB, respectively.This optical control suggests an interesting control of gain and matching for other microwave FET based active devices .

description: We present an equivariant bijection between two actions--promotion and rowmotion--on order ideals in certain posets. This bijection simultaneously generalizes a result of R. Stanley concerning promotion on the linear extensions of two disjoint chains and recent work of D. Armstrong, C. Stump, and H. Thomas on root posets and noncrossing partitions. We apply this bijection to several classes of posets, obtaining equivariant bijections to various known objects under rotation. We extend the same idea to give an equivariant bijection between alternating sign matrices under rowmotion and under B. Wieland's gyration. Finally, we define two actions with related orders on alternating sign matrices and totally symmetric self-complementary plane partitions.

description: A new predistortion scheme based on active devices is presented in this paper.Through a simplified theoretical analysis a preliminary dimensioning of the structure is first performed;then a circuit optimization, based on very accurate modeling of the various active and passive blocks,allows obtaining a significant reduction of intermodulation distortion (IM3)of the PA to be linearized. The proposed predistortion architecture has been verified using Agilent ADS simulator for accomplishing two-tone and 16QAM analyses,firstly by means of behavioral components;then a CAD implementation based on TriQuint Semiconductors library for GaAs MMIC process has been simulated,confirming the expected performances.Also a worst-case analysis has been performed,demonstrating the robustness of the proposed solution.

description: We consider invariant Riemannian metrics on compact homogeneous spaces G/H where an intermediate subgroup K between G and H exists, so that the homogeneous space G/H is the total space of a Riemannian submersion. We study the question as to whether enlarging the fibers of the submersion by a constant scaling factor retains the nonnegative curvature in the case that the deformation starts at a normal homogeneous metric. We classify triples of groups (H,K,G) where nonnegative curvature is maintained for small deformations, using a criterion proved by Schwachhöfer and Tapp. We obtain a complete classification in case the subgroup H has full rank and an almost complete classification in the case of regular subgroups.

Are dynamical quantum jumps detector-dependent?

description: Dynamical quantum jumps were initially conceived by Bohr as objective events associated with the emission of a light quantum by an atom. Since the early 1990s they have come to be understood as being associated rather with the detection of a photon by a measurement device, and that different detection schemes result in different types of jumps (or diffusion). Here we propose experimental tests to rigorously prove the detector-dependence of the stochastic evolution of an individual atom. The tests involve no special preparation of the atom or field, and the required efficiency can be as low as η~58%.

description: We investigate the orbital stability of a putative Jovian planet in a compact binary νOctantis reported by Ramm et al. We re-analyzed published radial velocity data in terms of self-consistent Newtonian model and we found stable best-fit solutions that obey observational constraints. They correspond to retrograde orbits, in accord with an earlier hypothesis of Eberle & Cuntz, with apsidal lines anti-aligned with the apses of the binary. The best-fit solutions are confined to tiny stable regions of the phase space. These regions have a structure of the Arnold web formed by overlapping low-order mean motion resonances and their sub-resonances. The presence of a real planet is still questionable, because its formation would be hindered by strong dynamical perturbations. Our numerical study makes use of a new computational Message Passing Interface (MPI) framework MECHANIC developed to run massive numerical experiments on CPU clusters.

description: We discuss the effect of mode transitions on the current (I) and temperature (T) dependent linewidth (Δf) in nanocontact based spin torque oscillators (STOs). At constant I, Δf exhibits an anomalous temperature dependence near the mode transitions; Δf may either increase or decrease with T depending on the position w.r.t. the mode transition. We show that the behavior of Δf as a function of I can be fitted by the single mode analytical theory of STOs, even though there are two modes present near the mode transition, if the nonlinear amplification is determined directly from the experiment. Using a recently developed theory of two coupled modes, we show that the linewidth near mode transition can be described by an "effective" single-oscillator theory with an enhanced nonlinear amplification that carries additional temperature dependence, which thus qualitatively explain the experimental results.

description: Die Kornentwicklung in Getreiden ist ein streng regulierter Prozess und abhängig von der Nährstoffzufuhr aus vegetativen Geweben. Die Entwicklung der Spelzen in Gerste ist eng an die Kornentwicklung gekoppelt und kann in drei Phasen unterteilt werden. Diese kennzeichnen den Übergang der Spelzen von Sink- zu Source-Geweben. Während der Vorspeicherphase dienen die Spelzen als temporäre Speicher und akkumulieren N-Verbindungen. Die beginnende Speicherstoffsynthese in den sich entwickelnden Körnern erhöht deren Sink-Stärke, wodurch in den Spelzen Remobilisierungsprozesse ausgelöst werden. N-Verbindungen werden ins Korn transportiert und anschließend beginnen die Spelzen zu seneszieren. Effiziente Nährstoffverlagerung ist von aktiven Transportprozessen abhängig. Anhand der Expressionsprofile von N-Transportern lassen sich Kandidaten mit spezifischen Funktionen in Sink- oder Source-Geweben unterscheiden. Die Erhöhung der Sink-Stärke während der Kornentwicklung kann sich positiv auf Ertrag und Proteingehalt in Weizen auswirken und stellt somit einen vielversprechenden Ansatzpunkt zur Verbesserung von Getreidesorten dar.
description: Seed development in cereals is a highly controlled process and depends on nutrient supply from vegetative tissues. The development of barley glumes is tightly coordinated with the developmental status of the grain, and can be separated into three phases that characterise glumes´ transition from sink to source tissues. During the pre-storage phase, glumes act as temporary resource buffers that accumulate N compounds. When grain sink-strength increases due to storage product accumulation, remobilisation processes are triggered, and N compounds are relocated to the grains, before glumes undergo senescence. Efficient nutrient exchange depends on active transport processes, and expression patterns of N transporters allows identifying candidates with specific functions either in sink or source tissues. The increase of sink-strength in developing grains can positively influence yield and protein content in wheat, and thus represents a promising approach for further crop improvement.

description: Upstream neutral modes, counter propagating to charge modes and carrying energy without net charge, had been predicted to exist in some of the fractional quantum Hall states and were recently observed via noise measurements. Understanding such modes will assist in identifying the wavefunction of these states, as well as shedding light on the role of Coulomb interactions within edge modes. In this work, performed mainly in the nu=2/3 state, we placed a quantum dot a few micrometers upstream of an ohmic contact, which served as a neutral modes source. We showed the neutral modes heat the input of the dot, causing a net thermo-electric current to flow through it. Heating of the electrons led to a decay of the neutral mode, manifested in the vanishing of the thermo-electric current at T>110mK. This setup provides a straightforward method to investigate upstream neutral modes without turning to the more cumbersome noise measurements.

description: Theoretical studies within the chiral unitary approach, and recent experiments, have provided evidence of the existence of two isoscalar states in the region of the $Λ(1405)$. In this paper we use the same chiral approach to generate energy levels in a finite box. In a second step, assuming that these energies correspond to lattice QCD results, we devise the best strategy of analysis to obtain the two states in the infinite volume case, with sufficient precision to distinguish them. We find out that using energy levels obtained with asymmetric boxes and/or with a moving frame, with reasonable errors in the energies, one has a successful scheme to get the two $Λ(1405)$ poles.

description: We examine the effects of pure additive noise on spatially extended systems with quadratic nonlinearities. We develop a general multiscale theory for such systems and apply it to the Kuramoto-Sivashinsky equation as a case study. We first focus on a regime close to the instability onset (primary bifurcation), where the system can be described by a single dominant mode. We show analytically that the resulting noise in the equation describing the amplitude of the dominant mode largely depends on the nature of the stochastic forcing. For a highly degenerate noise, in the sense that it is acting on the first stable mode only, the amplitude equation is dominated by a pure multiplicative noise, which in turn induces the dominant mode to undergo several critical state transitions and complex phenomena, including intermittency and stabilisation, as the noise strength is increased. The intermittent behaviour is characterised by a power-law probability density and the corresponding critical exponent is calculated rigorously by making use of the first-passage properties of the amplitude equation. On the other hand, when the noise is acting on the whole subspace of stable modes, the multiplicative noise is corrected by an additive-like term, with the eventual loss of any stabilised state. We also show that the stochastic forcing has no effect on the dominant mode dynamics when it is acting on the second stable mode. Finally, in a regime which is relatively far from the instability onset, so that there are two unstable modes, we observe numerically that when the noise is acting on the first stable mode, both dominant modes show noise-induced complex phenomena similar to the single-mode case.

description: Angesichts der stetig wachsenden Zahl der Endoprothesen-Implantationen an Hüft- und Kniegelenken und der erhöhten Lebenserwartung, steigt auch die Inzidenz postoperativer periprothetischer Femurfrakturen. Zu den Risikofaktoren zählen neben der generalisierten Osteoporose, Prothesenlockerungen, und Revisionseingriffe, wobei in den meisten Fällen ein Bagatelltraumata für die Fraktur verantwortlich ist. Die erfolgreiche operative Versorgung dieser Frakturen erfordert eine sorgfältige Therapieplanung. Neben der konventionellen und minimalinvasiven Frakturstabilisierung, steht der Prothesenwechsel als Therapieoption zur Verfügung. Die Wahl des Therapieverfahrens ist neben der Frakturlokalisation und Prothesenstabilität auch abhängig von der Knochenqualität und dem Allgemeinzustand der Patienten. Anhand einer retrospektiven klinischen Untersuchung von 46 Patienten mit postoperativer periprothetischer Femurfraktur, die zwischen 1990 und 2002 operativ behandelt wurden, sollen sinnvolle Therapiekonzepte vorgestellt werden.
description: In view of the rising number of hip and knee joint replacements and the increasing life expectancy, also the incidence of postoperative periprosthetic femur fractures is rising. Risk factors are as well generalized osteoporosis as loosening of the prosthesis and revision arthroplasty. In most cases minimal trauma is causal for the fracture. A successful surgical treatment requires a careful preoperative planning. Therapeutic possibilities are conventional and minimally invasive fracture stabilization and change of the prosthesis. The decision for the right treatment depends on the location of the fracture, the stability of the implant and also on the quality of bone and the patient’s general state of health. The aim of this retrospective clinical study of 46 patients with postoperative periprosthetic femur fractures, treated between 1990 and 2002, is, to present useful therapeutic procedures.

description: In a previous paper (arXiv:1011.1895), we showed that saturation models, constrained by e+p HERA data on inclusive and diffractive cross-sections, are in good agreement with p+p data at LHC in the soft sector. Particularly impressive was the agreement of saturation models with the multiplicity distribution as a function of $n_{\rm ch.}$. In this paper, we extend these studies further and consider the agreement of these models with data on bulk distributions in A+A collisions. We compare our results to data on central and forward particle production in d+Au collisions at RHIC and make predictions for inclusive distributions in p+Pb collisions at the LHC.

description: Die Dipeptidylpeptidase IV ist eine ubiquitäre und multifunktionelle prolinspezifische Serinprotease. Im Blut ist sie für die Inaktivierung der gastrointestinalen Peptidhormone GLP-1 und GIP verantwortlich. Beide Hormone stimulieren in strikter Abhängigkeit von der Blutglukosekonzentration die Insulinausschüttung des Pankreas. Die Inhibierung der Serum-DP IV könnte somit ein wirksames Mittel sein, die Stabilität von GIP und GLP-1 in vivo zu erhöhen und die Glukosetoleranz in Typ 2 Diabetikern zu verbessern. Die vorliegende Arbeit befaßt sich mit der Synthese und der enzymkinetischen Untersuchung von kompetitiven Inhibitoren der Dipeptidylpeptidase IV. Dabei wurden Verbindungen entwickelt deren geringe Stabilität unter physiologischen Bedingungen eine limitierte Inhibierung der Serum-DP IV ermöglichen, die Vorläufermoleküle der wirksamen Inhibitoren darstellen und eine präapplikative Stabilisierung von instabilen Substanzen zulassen, die eine kompartimentgerichtete Inhibierung der DP IV ermöglichen. Ausgewählte Verbindungen wurden hinsichtlich ihrer Fähigkeit zur Beeinflussung der Glukosetoleranz im normoglykämischen und hyperglykämischen Tiermodell untersucht. Es konnte gezeigt werden, daß Ile-Thia in der Ratte oral verfügbar ist, die Inhibierung der Serum-DP IV in normoglykämischen Wistar-Ratten keinen signifikanten Einfluß auf deren Glukosetoleranz nach einem oralen Glukosetoleranztest (OGTT) hat, die Inhibierung der Serum-DP IV in hyperglykämischen Zucker-Ratten deren Glukosetoleranz nach OGTT erheblich verbessert.
description: Dipeptidyl peptidase IV is an ubiquitous and multifunctional proline-specific serine protease. It was reported to be responsible for the inactivation of the gastrointestinal peptide hormones GIP and GLP-1. These hormones stimulate the pancreatic insulin secretion in a glucose dependent manner. The inhibition of serum-DP IV could be a new tool to enhance the stability of GLP-1 and GIP in vivo and to improve glucose tolerance in typ 2 diabetes. This dissertation deals with the synthesis and kinetic investigation of competitive inhibitors of DP IV. The following classes of compounds were developed: inhibitors with a limited stability under physiological conditions to control the period of enzyme inhibition, prodrugs of DP IV-inhibitors that allow the stabilisation of unstable substances, inhibitors that enable to inhibit the DP IV in various body compartments. A subset of compounds was investigated concerning their ability to influence the glucose tolerance in normoglycemic and hyperglycemic animals. It was shown that Ile-Thia is orally available in rats, inhibition of serum-DP IV has no significant influence on the glucose tolerance after OGTT in normoglycemic Wistar rats, inhibition of serum-DP IV in hyperglycemic Zucker rats enhances their glucose tolerance after OGTT remarkably.

Following children's lines of flight : possibilities for a pedagogy of listening
Creators: name: Kim, Bo Sun
Publisher: name: University of British Columbia

description: This case study examines young children’s ideas and narratives as these emerged through a project about the forest outside the children’s early childhood classroom. I followed the trajectory of the children’s learning processes by participating with them in various experiences in the forest over 16 weeks. The theoretical inspirations for this study include the postmodernist work of early childhood researchers Gunilla Dahlberg and Peter Moss; selected concepts of poststructural theorists, Gilles Deleuze and Félix Guattari; and the philosophical foundations of the Reggio Emilia approach to early childhood education. The children, teachers, and I visited the forest on numerous occasions. There the children generated hypotheses about phenomena, developed theories about their discoveries, and created original stories. Their ideas, concepts, narratives, and interactions became the foci of my study. The specific questions of this inquiry include: What happens when researchers and teachers follow children’s ideas and narratives through the philosophical lens of Deleuze and Guattari? How can a pedagogy of listening be understood as a way of co-constructing curriculum with children? What is the impact of a pedagogy of listening on early childhood curriculum and teaching? How can a teacher support the creation of learning contexts that will enrich and extend children’s thinking and learning? By employing a pedagogy of listening and pedagogical documentation, both taken from the practices found in the pre-schools of Reggio Emilia, I was able to follow what Deleuze and Guattari call “lines of flight,” the free movements of thought created by the four-year old participants in the study. I describe three events demonstrating how the children’s learning evolved and transformed as they encountered landscapes, materials and diverse perspectives. Throughout my analysis of these events, Deleuze and Guattari’s concept of the rhizome provides an illuminating metaphor for understanding children’s thinking as generative, interactive and dynamic. My findings provide powerful justification for an emergent curriculum based on children's individual and collective interests. My study also addresses the role of the teacher in early childhood education, emphasizing a pedagogy of listening as a valuable tool for critical reflection on teaching and learning.

description: Based on a conventional flash architecture a 4-bit GaAs analog to digital (A/D) converter has been designed using OMMIC-Philips GaAs foundry and particularly its commercial enhancement/depletion mode 0.18 µm pHEMT technology process. The ADC operates at 7.5 GHz sampling rate with full power analog input bandwidth from DC to Nyquist frequency. Differential source coupled FET logic (SCFL) was used and the complexity of the whole chip is more than 1900 active devices. The converter can be used in radar and software radio applications where there is requirement for high sampling rates in order the superheterodyne architecture for the down conversion to be avoided.
