description: We prepare packings of frictional tetrahedra with volume fractions ϕ ranging from 0.469 to 0.622 using three different experimental protocols under isobaric conditions. Analysis via X-ray micro-tomography reveals that the contact number Z grows with ϕ, but does depend on the preparation protocol. While there exist four different types of contacts in tetrahedra packings, our analysis shows that the edge-to-face contacts contribute about 50% of the total increase in Z. The number of constraints per particle C increases also with ϕ and even the loosest packings are strongly hyperstatic i.e. mechanically over-determined with C approximately twice the degrees of freedom each particle possesses.

description: In this paper the inﬂuence from substrate effects on the performance of wideband SiGe HBT mixer circuits is investigated. Equivalent circuit models including substrate networks are extracted from on-wafer test structures and compared with electromagnetic simulations. Electromagnetic simulations are also applied to predict short distance substrate couplinge effects. Simulation results using extracted equivalent circuit models and substrate coupling networks are compared with experimental results obtained on a wideband mixer circuit implemented in a 0.35µm, 60 GHz fT SiGe HBT BiCMOS process.

description: The purpose of this study is to investigate the factors that compelled the regulators to change the broker credit directives in the Sri Lankan Stock Market. This study considers the monthly returns based on the All Share Price Index of the Colombo Stock Exchange, and the regulatory changes in broker credit directives by the Securities and Exchange Commission over the period from the year 2010-2019. The Generalized Autoregressive Conditional Heteroskedasticity model was used to estimate the market volatility over the sample period. The study also used a Binary Probit regression model to identify the factors affecting the change in broker credit directives. According to the Probit regression results, Sri Lankan macro-economic factors significantly affect credit directive changes. It is also evidenced that the regulators change credit directives in response to market factors that create a suspected speculative behavior of market participants.

description: We derive the Euler-Lagrange equations for minimizers of causal variational principles in the non-compact setting with constraints, possibly prescribing symmetries. Considering first variations, we show that the minimizing measure is supported on the intersection of a hyperplane with a level set of a function which is homogeneous of degree two. Moreover, we perform second variations to obtain that the compact operator representing the quadratic part of the action is positive semi-definite. The key ingredient for the proof is a subtle adaptation of the Lagrange multiplier method to variational principles on convex sets.

description: A novel frequency domain-based method for the extraction of one-port device’s non-linear constitutive relations directly from vector large-signal measurements is presented. A distinctive characteristic of the method is that it provides directly the charge-voltage state-function, without the need to perform the integration of the capacitance-voltage function as required by its time domain-based counterpart. The capabilities of the method are demonstrated by extracting the non-linear state-functions of a microwave diode from large-signal data generated by harmonic balance analysis, and the non-linear gate-source state-functions of a HEMT device under ‘cold-FET’ bias conditions from measured data.

description: Autoencoders are unsupervised machine learning circuits whose learning goal is to minimize a distortion measure between inputs and outputs. Linear autoencoders can be defined over any field and only real-valued linear autoencoder have been studied so far. Here we study complex-valued linear autoencoders where the components of the training vectors and adjustable matrices are defined over the complex field with the $L_2$ norm. We provide simpler and more general proofs that unify the real-valued and complex-valued cases, showing that in both cases the landscape of the error function is invariant under certain groups of transformations. The landscape has no local minima, a family of global minima associated with Principal Component Analysis, and many families of saddle points associated with orthogonal projections onto sub-space spanned by sub-optimal subsets of eigenvectors of the covariance matrix. The theory yields several iterative, convergent, learning algorithms, a clear understanding of the generalization properties of the trained autoencoders, and can equally be applied to the hetero-associative case when external targets are provided. Partial results on deep architecture as well as the differential geometry of autoencoders are also presented. The general framework described here is useful to classify autoencoders and identify general common properties that ought to be investigated for each class, illuminating some of the connections between information theory, unsupervised learning, clustering, Hebbian learning, and autoencoders.

description: This article deals with the improvement of noise figure for microwave active recu rsive filters. We show, using a noise wave analysis [1], how the noise factor of a first-order recursive structure can he effectively minimized, by using appropriate unbalanced power dividers/combiners in association with an amplifier of given gain and noise factor values. We start from measured results of monolithic filters and validate our approach with simulated examples.

description: Among the noise parameters expressed in the reflection coefficient form ( Fo, IFOI,
/Fo and rn ), the noise resistance rn is of critical importance lo the design of low-noise
receivers. Very low values of rn allow for optimizing the performance    of broad band
amplifiers in receiver front-ends.
We here present an analysis performed on typical circuit models of FET's which was aimed at
assessing the key elements influencing the behavior of rn at microwave frequencies.
We found that the noise performance can be improved by tuning the value of the input (gate,
source) inductances which are responsible of the U shaped curves typically observed for rn in
MESFET's and HEMT's.

description: This work reports on the design and measured performance of a single-ended upconverter at Ka-band. The upconverler uses a 6.5x3[im2 GalnP/GaAs HBT as the nonlinear mixing element. The LO is injected into the emitter of the 1IBT, the IF is applied to the base, and the RF is extracted from the collector. This topology utilizes all three ports of the transistor and avoids the need for a diplexer or other method of combining or separating the signals. The IF, LO, and RF frequencies are 3.6 GHz, 26.5 GHz, and 30.1 GHz respectively. The measured conversion loss was less than 2dB at the center of the band while the third order intercept point was -2dBm. These results were obtained with an LO power of only -2dBm. The overall chip size is 3.7x2.5mm2.
The Multicultural Cafe : the perceived impacts of volunteering in a service learning platform from the perspectives of adult learners of English as a second or additional language
Creators: name: Riley, Tracy Jean
Publisher: name: University of British Columbia
Year: 2014

description: This qualitative study explores the perceived impacts of volunteering in a service learning platform from the perspective of immigrants, who are also adult learners of English as an Additional Language (EAL), or English as a Second Language (ESL). This study recognizes that the goal of learning English for immigrants is to be able to converse, connect, and contribute as a valued community member. The hegemonic practice of sequestering newcomers and immigrants into language training classes can further their linguistic and social isolation and marginalization by restricting their access to authentically engage with English speakers in their community. This study investigates how adult immigrant English Language Learners (ELLs) invested in a service learning experience of volunteering for a small non-profit food service business at a local community college can facilitate a connection to the community whereby increasing perceived language skills and confidence. For this study, 10 adult immigrants who speak ESL or EAL participated. The data was collected from a questionnaire, an individual interview, and a focus group. The results revealed three themes pertaining to the social, personal, and transformational realms of learning. The social realm aligned with a sociocultural perspective in which social and cultural capital, bridging and bonding capital, communities of practice, and communities of contribution are highlighted. The personal realm reveals the significance of the affective-emotional aspects of language learning alongside agency and positive identity construction. Finally, this study reveals a connection between service learning and transformational learning. The overall conclusion of this study determines that service learning can be a meaningful endeavour for adult immigrants because it has the potential to transform marginalized voices into valued voices as they connect and contribute community.

description: We find that if we live at the center of an inhomogeneity with total density contrast of roughly 0.1, dark energy is not a cosmological constant at 95% confidence level. Observational constraints on the equation of state of dark energy, w, depend strongly on the local matter density around the observer. We model the local inhomogeneity with an exact spherically symmetric solution which features a pressureless matter component and a dark-energy fluid with constant equation of state and negligible sound speed, that reaches a homogeneous solution at finite radius. We fit this model to observations of the local expansion rate, distant supernovae and the cosmic microwave background. We conclude that the possible uncertainty from large-scale structure has to be taken into account if one wants to progress towards not just precision but also accurate cosmology.

This paper describes the architectures chosen for both devices and will focus on the design techniques that should be adopted when RF signals, with different power levels and/or at different frequencies, must meet on the same chip without mutual interferences. The paper will also focus on the electrical modelling of large IC packages for digital VLSI IC's to be used at L-band frequencies. In the cases herein described, low cost and high volume production are not mandatory, while high performance, very high yields, multifunctions on chip, no needs of external interfaces and tuning components, freehold property of the devices and fast and reliable circuit design are the requirements.

Risk management of acid rock drainage under uncertainty
Creators: name: Betrie, Getnet Dubale
Publisher: name: University of British Columbia
Year: 2014

description: Acid rock drainage (ARD) is a major environmental problem that causes local and global pollution. ARD occurs when sulfide bearing materials are exposed to oxygen and water during mining activities. This reaction between sulfide and oxygen with the presence of water generates elevated metals and metalloids that may cause potential environmental and human health risks. The remediation costs of potentially acid-generating wastes at abandoned minesites are estimated to be over $20 billion in USA. The major objective of this research is to propose a risk management framework for ARD that can improve the prediction of ARD chemistry, assess and manage environmental and human health risks to guide decision-making under uncertainty. The proposed framework consists of methodologies for filling in missing data, predict ARD chemistry, assess environmental risks, and manage risks of ARD. In the first methodology, missing values of ARD data are filled in using imputation algorithms that reduce loss of information and introduction of biases. After having the complete data, future ARD chemistry is predicted using machine learning techniques. The predictive uncertainty due to data, parameters and model is quantified using a probability bounds approach. Models are integrated using aggregation methods to reduce the uncertainty of the individual model. Case studies in minesites show that the developed methodology improves the prediction of future ARD chemistry under uncertainty. For ecological and human health risks assessment of ARD, two methodologies are developed based on the fugacity and PHREEQC approaches. The fugacity and PHREEQC approaches are applied in minesites with limited and adequate hydrogeological information, respectively. Case studies in minesites show that these methodologies are useful to quantify ecological and human health risks in the mining industry. In addition, they quantify the associated uncertainties in the risk assessments using the probability bounds and fuzzy-probabilistic approaches. For risk management of ARD, a methodology that uses multicriteria decision analysis (MCDA) and probabilistic approaches is developed. The methodology enables decision-makers to evaluate mitigation measures with various criteria, such as risk, cost, and technical feasibility, identifies the optimal mitigation measure, and quantifies the associated uncertainties in decision-making. In general, it is believed that the proposed framework enhances the decision-making ability of the mining industry under uncertainty and reduces environmental risks and remediation costs of managing ARD.

description: From 1919 through the early 1920s, Americans energetically memorialized their role in the First World War. They built literally thousands of community monuments and functional memorials (such as buildings and parks), implemented an elegant scheme for battlefield commemoration in Europe, established Armistice Day as a national holiday, and emulated France and Great Britain by honoring an unknown soldier. There was no consensus, however, about the meaning of the war or the way in which it should be commemorated and remembered. As a result, collective memory of the conflict splintered into competing versions of the past and faded quickly.

description: Incessant wars from 1912 to 1922 accelerated socio-political change and facilitated transition from empire to republic. The nation state was founded on civic citizenship and education in the official language. The revolutionary change in the legal system, discarding religious law altogether dismantled former subjugations. The Civil Law of 1926 and secularization mostly benefited gender relations and social change. Although remaining non-Muslims were accommodated by a renewed social contract, the leadership whose political socialization was formed during the waning years of empire, continued with abated discrimination towards them. On the diplomatic front, however, Ankara distinguished itself by reconciliation with former adversaries, and solved outstanding security issues peacefully.

Functional Data Analysis and Extensions for Financial Data

Year: 2022

description: It’s worth noting that functional data analysis greatly enriches existing data analysis methods. It brings a broader perspective to investigate data structures. Thus, this thesis focuses on the field of functional data analysis and its extension methods. We begin by revisiting the fundamental methodologies of functional data analysis that support the overall concept of this thesis. After this explanatory stage, this thesis contributes three main parts. Part one concentrates on the application of the functional data analysis techniques based on the functional high-frequency intra-day volatility dataset. Part two is intended for realising the real-time short-term dynamic updating forecasts. Specifically, we apply the univariate time series forecasting method and the multivariate time series forecasting method to obtain the principal component scores forecasting. Also, to forecast the dynamic updating, we adopt five models and compare their results in light of the accuracy of measuring. The contribution of this part lies in the incorporation of the rolling window methods into the sequence of functional time series forecasting techniques. And the remaining parts consist in developing the novel functional curve clustering algorithm, which includes proximity measurement and time-shift clustering.
After conducting the numerical simulation experiments, we find the proposed model has an outstanding performance with respect to functional data clustering. Also, identifying the proximity threshold is a central issue in the proposed algorithm. Then, the proximity measurement algorithm is used on a newly gathered COVID-19 functional dataset, a topic of high concern. Meanwhile, we apply the time-shift clustering algorithm to another freshly collected NASDAQ Composite functional dataset. And both two models deliver remarkable outcomes in terms of identifying trajectories of functional curves and accomplishing further clustering. Finally, through this thesis, the effectiveness of the functional data analysis techniques in the application is demonstrated, and the superiority of the functional expansion methods is verified.

The frontiers of Central Europe were fiercely embattled in a civil war between the national armies of the evolving new states.

description: The aim of this paper is to introduce an approach to the (strong) Novikov conjecture based on continuous families of finite dimensional representations: this is partly inspired by ideas of Lusztig using the Atiyah-Singer families index theorem, and partly by Carlsson's deformation $K$--theory. Using this approach, we give new proofs of the strong Novikov conjecture in several interesting cases, including crystallographic groups and surface groups. The method presented here is relatively accessible compared with other proofs of the Novikov conjecture, and also yields some information about the $K$--theory and cohomology of representation spaces.

description: Africans across the continent resisted colonial demands and took up arms against European colonizers during World War I. This essay presents three ways of recognizing and analyzing such acts of resistance. First, many Africans refused increased colonial labor demands. Second, religious movements shaped how African peoples interpreted what was happening to their societies once the war in Africa began. Finally, some African polities saw the war as an opportunity to restructure political relationships between themselves and European colonizers.

description: In questo lavoro l'analisi del risck sharing tra le regioni italiane rispetto alle fluttuzioni economiche regionali di lungo e di breve periodo viene affrontata facendo ricorso a modelli autoregressivi vettoriali (VAR) i quali, riparametrizzati nella forma a meccanismodi correzione dell'equilibrio (VEqCM), permettono di saggiare tutte le implicazioni della teoria senza l'uso preventivo di filtri o trasformazioni delle variabili, e sopratutto senza vincoli sull'omogeneità delle preferenze nelle diverse regioni. Le stime sul periodo 1960-1995 mostrano che le preferenze non sono omogenee e che, considerando opportunemente l'eterogeneità regionale nei parametri di preferenza, l'evidenza a favore del risk sharing è molto più marcata di quanto comunemente ritenuto o evidenziato in precedenti lavori. I risultati indicano che nel sistema regionale italiano gli strumenti di risk sharing operanti attraverso i mercati (investimenti, prestiti, migrazioni) o attraverso il welfare state (cassa integrazione, indennitò di disoccupazione) consentirevvero la stabilizzazione ottimale delle economie regionali ma la concreta efficacia di tali strumenti è influenzata negativamente dall'ambiente in cui operano: l'avversione al rischio ostacol infatti sia la mobilità della forza lavoro sia la diversificazione dei portafogli e limita quindi l'efficacia delle strategie di stabilizzazione attraverso il risk sharing.

description: Flüssigkristalline Phasen werden gewöhnlich von formanisotropen Molekülen oder amphiphilen Materialien ausgebildet. Obwohl die synthetisierten Verbindungen (Pentaerythritolderivate, acylierte Polyhyydroxyverbindungen und Aminoalkohole, ein Tetraphenylmethan- und ein Tetraphenylstannanderivat) sich weder durch eine formanisotrope Molekülgestalt auszeichnen noch als typische Amphiphile bezeichnet werden können, zeigen einige von ihnen kolumnare Mesophasen. Die flüssigkristallinen Eigenschaften beruhen auf der Microsegregation der unverträglichen Molekülbereiche in getrennte Microdomänen. Es konnte gezeigt werden, daß in Analogie zu Block-Copolymeren die Vergrößerung der Unverträglichkeit der einzelnen Molekülbereiche und die Erhöhung der Anzahl der miteinander verbunden Gruppen einen Anstieg der Mesophasenstabilität zur Folge hat. Die beschriebenen Verbindungen können als die einfachsten sternförmigen Blockmoleküle betrachtet werden, die flüssigkristalline Phasen ausbilden.
description: Liquid crystalline phases are commonly formed by anisometric molecules or by amphiphilic materials. Despite the fact that the synthesized compounds (pentaerythol derivatives, acylated polyhydroxy compounds and aminoalcohols, a tetraphenylmethan derivative, a tetraphenylstanne) have neither a specific anisometric shape nor a strong amphiphilicity, some of them show columnar liquid crystalline mesophases. The mesogenity is mainly driven by micro segregation of the incompatible molecular parts into well-organized different microdomains. It was shown that, in analogy to block copolymers, the mesophase stability rises on increasing the degree of incompatibility between the different molecular segments and on enlarging the number of repeat units connected with each other. The molecules described herein can be regarded as the most simple star-shaped block molecules forming liquid crystalline phases.

description: Das Y-box binding protein-1 (YB-1) stellt einen wichtigen Mediator in Entzündungsreaktionen und Fibrosierungsprozessen dar. YB-1 beeinflusst die Transkription und Translation einer Vielzahl von Genen, wie z.B. der pro- inflammatorischen Gene RANTES/CCL5 sowie pro-fibrotischer Gene wie TGF-β. Da der konventionelle homozygote Knockout von Ybx1 embryonal letal endet, generierten wir eine Rosa26CreERT2-induzierbare Ybx1 Knockout-Maus, um den Einfluss des Ganzkörperknockouts von YB-1 auf Zellfunktionen und Krankheitsentwicklung zu untersuchen. Als Krankheitsmodell diente die unilaterale Ureterobstruktion (UUO), welche eine tubulointerstitielle Entzündung und progrediente Nierenfibrose auslöst. Im UUO-Modell zeigte sich in Wildtyp-Mäusen eine starke Immunzellinfiltration, während die YB-1ΔRosaERT2-Knockout-Mäuse eine signifikant geringere Infiltration von Leukozyten aufwiesen. Weiterführend konnten wir 14 Tage nach UUO eine signifikante Reduktion der Ablagerung von Kollagenen im Extrazellulärraum nachweisen. Zur Erweiterung unseres Verständnisses der Entzündung und Fibrose analysierten wir das entzündliche Mikromilieu (wie TGF-β, RANTES/CCL5) in UUO-Nieren. Alle Fibrose-relevanten Zytokine waren im Vergleich zu Wildtypen erniedrigt. In dieser Arbeit konnten wir zeigen, dass eine einmalige Induktion der Cre-Rekombinase ausreicht, um einen YB-1 Knockout zu generieren, der zu signifikanten Veränderungen in der Immunzellinfiltration nach UUO führt sowie zu weniger Kollagenablagerung und einer Reduktion Fibrose-relevanter Zytokine.

description: Bei der Therapie von Lebermalignomen wird in der Regel eine chirurgische Resektion angestrebt. Ist das hierfür erforderliche Leberrestvolumen (FLR) nicht gegeben, kann durch die Anwendung von hypertrophieinduzierenden Verfahren eine Erhöhung des FLR erzielt und so ggf. eine Resektabilität erreicht werden. Das Ziel der Dissertation ist die Analyse von Volumenänderungen der Lebersegmente II/III nach Durchführung einer rechtshepatischen CT-gesteuerten interstitiellen HDR-Brachytherapie. Hierfür wurden Daten von insgesamt 61 Patienten mit primären und sekundären Lebermalignomen analysiert und auf Basis von MRT-Datensätzen (prä- und postinterventionell) volumetrisch ausgewertet. Insgesamt konnte eine signifikante Volumenzunahme der Segmente II/III mit einer relativen FLR-Änderung von 24,77 % gezeigt werden. Eine vorliegende Leberzirrhose sowie ein erhöhtes Patientenalter wirkten sich negativ auf die rel. FLR-Änderung aus. Unter Berücksichtigung der individuellen Mindestresektionsgrenzen hätten die nachgewiesenen Volumenänderungen bei einem Teil der Patienten mit einem initial zu kleinen FLR die volumenbezogenen Voraussetzungen für eine sekundäre Resektion geschaffen. Die Bewertung und Einordnung der CT-HDRBT im Kontext etablierter hypertrophieinduzierender Verfahren muss insbesondere vor dem Hintergrund der Wirkungsaspekte Volumenänderung und Tumorkontrolle diskutiert werden.

description: In der vorliegenden Arbeit beabsichtigten wir, die Charakteristika und Krankheitsverläufe von Magenkarzinompatienten mit und ohne Autoimmungastritis (AIG) im Rahmen einer multizentrischen Fall-Kontroll-Studie zu vergleichen. Zwischen April 2013 und Mai 2017 wurden im Zuge des star-Projekts (Gastric Cancer Research) 759 Magenkarzinompatienten in verschiedenen deutschen Zentren rekrutiert. Magenkarzinompatienten mit histopathologischen Merkmalen einer AIG wurden identifiziert (N=28) und mit Magenkarzinompatienten ohne AIG (N=56) verglichen. Paraffineingebettete Proben der Magenschleimhaut von Magenkarzinompatienten mit und ohne AIG wurden einem Referenz- Pathologen zur zentralen Beurteilung vorgelegt. Gastrointestinale Symptome wurden mit Hilfe eines Fragebogens und telefonischen Interviews erfasst. Darüber hinaus wurden Überlebenszeitanalysen erstellt. In Zusammenschau der Ergebnisse konnten wir erstmalig belegen, dass sich Magenkarzinompatienten mit AIG in Bezug auf histopathologische, serologische und klinische Eigenschaften signifikant von Magenkarzinompatienten mit Helicobacter pylori (H. pylori)-induzierter Gastritis unterscheiden. Laut unserer Daten haben AIG-Patienten, die ein Magenkarzinom entwickeln, eine bessere Prognose als Magenkarzinompatienten ohne AIG. Hauptverantwortlich ist das Vorliegen einer perniziösen Anämie (PA), die zu einer früheren Diagnose eines Magenkarzinoms bei AIG- Patienten führt und mit einem längeren Überleben assoziiert ist. Ein stärkeres Bewusstsein für das Magenkarzinomrisiko bei Patienten mit PA ist somit entscheidend für die Verbesserung ihres klinischen Krankheitsverlaufs.
