Reflectance modeling

description: We propose a technique to efficiently importance sample and store fluorescent spectral data. Fluorescence behaviour is properly represented as a re-radiation matrix: for a given input wavelength, this matrix indicates how much energy is re-emitted at all other wavelengths. However, such a 2D representation has a significant memory footprint, especially when a scene contains a high number of fluorescent objects, or fluorescent textures. We propose to use Gaussian Mixture Domain to model re-radiation, which allows us to significantly reduce the memory footprint. Instead of storing the full matrix, we work with a set of Gaussian parameters that also allow direct importance sampling. When accuracy is a concern, one can still use the re-radiation matrix data, and just benefit from importance sampling provided by the Gaussian Mixture. Our method is useful when numerous fluorescent materials are present in a scene, an in particular for textures with fluorescent components.

What satisfies a curious mind? curiosity prompts novel reward seeking
Creators: name: Wang, Chen
Publisher: name: University of British Columbia
Year: 2014

description: In this age of information overload, consumers are bombarded with various curiosity-inducing stimuli from newspapers, TV programs, movies, web banners, etc. Despite its ubiquity in the consumption world, curiosity has surprisingly received little attention in cognitive psychology and consumer behavior research (Kang et al. 2009; Menon and Soman 2002). In the limited research on state curiosity, most attention has been directed to its impact on people’s search for domain-specific information that closes the knowledge gap (Menon and Soman 2002; van Dijk and Zeelenberg 2007). However, as curiosity is also an appetitive state that possesses driving forces (Blumenberg 1983; Loewenstein 1994), it is possible that curiosity could motivate reward-seeking behaviors other than information seeking. My dissertation investigates the impact of curiosity, a cognitive deprivation arising from the perception of a gap in knowledge (Loewenstein 1994), on consumers’ subsequent reward-seeking behaviors. I find that curiosity motivates people to seek rewards, particularly novel rewards, in other unrelated domains, such as physical domains (e.g., money, food) and social domains (e.g., social friendship, charitable donation). This effect occurs as a result of a general appetitive drive and an open mindset, which are both activated by exposure to curiosity cues. I further identify that information content moderates this effect; when people are curious about threatening information, the effect of curiosity on the spillover reward-seeking tendency is mitigated. This research contributes to both the curiosity and the reward-seeking literature. While prior research has shown that curiosity motivates people to seek rewards in the cognitive domain by searching for the missing information, I show that this general motivational dimension of curiosity can prompt people to engage in reward-seeking behaviors in other unrelated domains. Further, I add to the existing spillover reward-seeking studies by showing that such effect induced by curiosity is particularly pronounced for novel rewards. This research also contributes to the reward-seeking literature by exploring how the spillover reward-seeking effect extends to the intangible cognitive and social domains (e.g., cognitive deprivation, social rewards).

Zavrelimyia punctatissima

description: Zavrelimyia punctatissima (Goetghebuer, 1934)
Material examined.
• 6 pupal exuviae, Taul Stiol (R 4), 3 July 2023.
Distribution.
West Palaearctic. The species is known from a few European countries: Austria, France, Germany, Italy, Norway, and Slovakia (Ashe and O’Connor 2009).
Habitat.
It is a cold-stenothermal species adapted to live in oligotrophic waters with high oxygen concentrations (Boggero and Lencioni 2006). Boggero (2018) considers it strictly rheophilous. The species is a typical inhabitant of the littoral, inlets and outlets of alpine lakes (Rossaro et al. 2006; Hamerlík and Bitušík 2008; Steingruber et al 2013).
Remarks.
Pupal exuviae closely resemble those of Zavrelimyia hirtimana (Kieffer, 1918), but all collected specimens exhibit very small plastron plates. The plastron plate diameter to thoracic horn length (0.054 –0.055) aligns with the diagnosis of Langton and Visser (2003) for Z. punctatissima.

description: We present a single-image data-driven method to automatically relight images with full-body humans in them. Our framework is based on a realistic scene decomposition leveraging precomputed radiance transfer (PRT) and spherical harmonics (SH) lighting. In contrast to previous work, we lift the assumptions on Lambertian materials and explicitly model diffuse and specular reflectance in our data. Moreover, we introduce an additional light-dependent residual term that accounts for errors in the PRTbased image reconstruction. We propose a new deep learning architecture, tailored to the decomposition performed in PRT, that is trained using a combination of L1, logarithmic, and rendering losses. Our model outperforms the state of the art for full-body human relighting both with synthetic images and photographs.

description: A model for simulating the DC characteristics of the gate junction in High Electron Mobility Transistors is presented. The equations for the gate current of FET's in the SPICE simulator are modified to account of the HEMT gate current in a wide range of bias conditions. It is proven that a four-diodes model yields to a satisfactory agreement with the experimental data. The presented model can be employed either by implementing the modified equations in the simulator code or by a device macro modeling.

description: Total joint arthroplasty is a highly successful surgical procedure, immensely increasing the quality of life of patients who suffer from chronic degenerative joint diseases. In future generations of younger and more active patients the number of primary total joint arthroplasties is going to continue to rise. Concomitant with that, the number of revision total joint arthroplasties will also rise. These revision arthroplasties are more challenging and more threatening to the patients’ health than primary arthroplasties. This single-institutional analysis of 335 revision total joint arthroplasty cases performed during the years 2011 and 2016 at the department for orthopaedic surgery of the University hospital Magdeburg revealed not only that there is a difference in the reasons for revision between the male and female sex but also a striking correlation between the male sex and the incidence of periprosthetic joint infections. Also, a risk factor analysis for some of the most common risk factors for the incidence of periprosthetic joint infections exposed a more than six times higher risk for the incidence of periprosthetic joint infections in patients who already underwent a revision surgery. The data also revealed a more than three times higher risk of periprosthetic joint infections in the male sex when compared to the female sex. These results should be considered during the treatment of patients with primary and revision total joint arthroplasties. Not only, but especially male patients with complications of a total joint arthroplasty require a thoroughly performed diagnostical process to detect periprosthetic joint infections in an early state.
An improved C-V model of GaAs MESFETs for CAD of high speed circuits and broadband amplifiers

description: In this paper a semiempirical capacitance
model of GaAs FET, very useful for CAD of MMIC, is
proposed. The model fits the results of two dimensional
(2-D) simulations of device behaviour, accounting for the
most   important   microwave   effects,   by   means   of the
determination   of an  effective   shape   of the   depletion
region in the active channel.
Simple physical equations and a few effective empirical
parameters,    with   a   precise   physical   meaning,    are
employed.  So the initial estimation of parameters and
their extraction procedure result to be very easy.
In spite of its semiempirical nature the model does not
leave the control over physical and technological device
parameters to circuit designer, necessary to achieve a
reliable design.
The model usefulness and accuracy are experimentally
confirmed to be very satisfactory for different kinds of
MESFETs.

Procladius sagittalis

description: Procladius (Holotanypus) sagittalis (Kieffer, 1909)
Material examined.
• 11 pupal exuviae, 1 male, Lake Vartopul 1 (M 3), 1 July 2024 • 25 pupal exuviae, 2 pupae, 1 pharate adult – male, Lake Vartopul 2 (M 4), 1 July 2024.
Distribution.
Palaearctic and Oriental. Distributed from Europe and North Africa through Iran to Japan and the Russian Far East. One record is known from China (Ashe and O’Connor 2009; de Jong 2016).
Habitat.
Generally, larvae of the subgenus Holotanypus are dwellers of stagnant and slow flowing waters regardless of size or volume. Langton (1991) noted that P. sagittalis typically occurs in shallow water under 2 m deep, which aligns with the findings from small-volume habitats (e. g., Velasco et al. 1993; Hirabayashi et al. 2004). However, the species has also been recorded from artificial ponds and reservoirs, as well as from backwaters, and large rivers (Bitušík 1993; Evrard 1994; Móra et al. 2010; Quintana et al. 2018). It should be noted that ecological information on the species could be more accurate if the identification of the preimaginal stages were more reliably resolved.
Remarks.
Identification of the pupal exuviae, and even adult males of Procladius (Holotanypus) is extremely challenging (Vallenduuk and Moller Pillot 2007). The extended key for exuvia (Langton et al. 2013) is not reliably applicable to Procladius material collected from the Maramures lakes due to the variability of the tergite armament. Notably, the distinctive “ fish scale ” armament typical of P. choreus can also appear in some specimens of Procladius Pe 3. The parameters of the thoracic horns appear to be more reliable characteristics for identification.
Thus, we propose a model that classifies input data with 97 % accuracy, achieving 100 % for P. sagittalis and 96 % for P. choreus. Based on the decision tree trained on our dataset, we constructed an identification key for distinguishing the aforementioned Procladius species (Table 2). We are aware of the tentative nature of the key and acknowledge that a larger dataset would improve the tuning and evaluation of the proposed system. Therefore, the proposed key should be used with great caution.

description: We consider a toy model with flat thin branes embedded in a 5-dimensional Weyl integrable manifold, where the geometric Weyl scalar provides the material that constitute the brane configurations. The brane configuration is similar to the Randall-Sundrum model. However, it is found that the massless graviton is localized on the brane with negative tension. So in order to solve the gauge hierarchy problem our world should be confined on the positive tension brane, and this is crucial to reproduce a correct Friedmann-like equation on the brane. The spacings of graviton mass spectrum are very tiny, but these massive gravitons are hidden in low energy experiments because they are weakly coupled with matter on the brane.

Material examined.
• 64 pupal exuviae, 1 pharate adult – male, Lake Vartopul 2 (M 4), 1 July 2024 • 1 pupal exuviae, Taul Hardau (R 3), 6 July 2023.
Distribution.
Palaearctic. Known from several European countries, as well as Turkey and Algeria (Ashe and O’Connor 2009).
Habitat.
The species is typical of small, acidic, stagnant waters in moorlands and peat bogs. In addition to tolerating low pH, it can withstand low oxygen levels in polyhumic waters; however, larvae are also found in lake littorals and small streams with slow currents (Moller Pillot 2013 and references therein). In the Western Carpathians, pupal exuviae were collected from a small, non-acid sub-alpine lake (Bitušík et al. 2006). The species is frequently recorded in temporary pools and ponds (e. g., Bazzanti et al. 1997; Puntí et al. 2007), as well as ephemeral waters (Moller Pillot 2003), indicating relatively high dispersal potential of females.
Remarks.
The findings indicate the humic conditions of Taul Hardau and suggest at least partial drying of Lake Vartopul 2.

The impact of fear on brand attachment
Creators: name: Dunn, Lea Hunter
Publisher: name: University of British Columbia
Year: 2014

description: Throughout their daily lives consumers experience a vast array of emotions. At times these emotions are directly related to a consumption context, while other times these emotions are unrelated. While previous research on incidental emotion has generally found that negative emotions have negative outcomes for brands, the explicit effect of fear has been understudied. The present research explores the effect of fear on brand attachment. Across six experimental studies, this dissertation provides insight into the process by which consumers cope with fear and how this coping method has positive implications for brand attachments. This dissertation suggests that because people cope with fear through affiliation with others, in the absence of other individuals, consumers may seek affiliation with an available brand. This, in turn, will enhance emotional attachment to that brand. The first four studies of the dissertation highlight the basic process by which fear enhances emotional brand attachment. First, I show the basic fear-attachment effect (pilot study and study 1). Specifically, I show that a fearful experience, compared to a happy, sad, or exciting experience, results in higher emotional attachment to brands, even when consumers are unfamiliar with the brand. Second, I provide initial evidence for desire for affiliation, or perceived shared experience, as the underlying mechanism of the effect (study 1 and 2). Third, I provide stronger evidence for the process by ruling out simple increased consumption as an alternative explanation for the fear-attachment effect. In the last two studies, I examine factors that influence the fear-attachment process. First, I highlight the importance of product presence during the fear experience in order to allow for consumer coping (study 4). Second, I illuminate a distinction between two forms of brand attachment measurement: Thomson et al. (2005)’s emotional attachment and Park et al. (2010)’s more cognitive brand attachment. I demonstrate that a fear experience can facilitate initial emotional, but not cognitive, attachment without the necessity of time. In addition, this initial emotional attachment helps promote cognitive attachment over time (study 4). Third, I show that the fear-attachment process is unique to brands and not products in general (study 5).

description: We study the response of a single-component pair-correlated baryonic Fermi-liquid to density, spin, and their current perturbations. A complete set of response functions is derived in the low-temperature regime both within an effective theory based on a small momentum transfer expansion and within a numerical scheme valid for arbitrary momentum transfers. A comparison of these two approaches validates the perturbative approximation within the domain of its convergence. We derive the spectral functions of collective excitations associated with the density, density-current, spin, and spin-current perturbations. The dispersion relations of density and spin fluctuations are derived and it is shown that the density fluctuations lead to exciton-like undamped bound states, whereas the spin excitations correspond to diffusive modes above the pair-breaking threshold. The contribution of the collective pair-breaking modes to the specific heat of neutron matter at subnuclear densities is computed and is shown to be comparable to that of the degenerate electron gas at not too low temperatures.

description: Visualizing volumetric medical datasets in a virtual reality environment enhances the sense of scale and has a wide range of applications in diagnostics, simulation, training, and surgical planning. To avoid motion sickness, rendering at the native refresh rate of the head-mounted display is important, and frame drops have to be avoided. Despite these strict requirements and the high computational complexity of direct volume rendering, it is feasible to provide a comfortable experience using volume ray casting on modern hardware. Many implementations use precomputed gradients or illumination to achieve the targeted frame rate, and most rely on acceleration structures, such as distance maps or octrees, to speed up the ray marching shader. With many of these techniques, the opacity of voxels is baked into the precomputed data, requiring a recomputation when the opacity changes. This makes it difficult to implement features that lead to a sudden change in voxel opacity, such as real-time transfer function editing, transparency masking, or toggling the visibility of segmented tissues. In this work, we present an empty space skipping technique using an octree that does not have to be recomputed when the transfer function is changed and performs well even when more complex transfer functions are used. We encode the content of the volume as bitfields in the octree and are able to skip empty areas, even with transfer functions that cannot efficiently be represented as a simple range of voxel values. We show that our approach allows arbitrarily editing of the transfer function in real-time while maintaining the target frame rate of 90 Hz.

description: We study the evolution of galaxy rest-frame ultraviolet (UV) colors in the epoch 4 < z < 8. We use new wide-field near-infrared data in GOODS-S from the CANDELS, HUDF09 and ERS programs to select galaxies via photometric redshift measurements. Our sample consists of 2812 candidate galaxies at z > 3.5, including 113 at z = 7 to 8. We fit the observed spectral energy distribution to a suite of synthetic stellar population models, and measure the value of the UV spectral slope (beta) from the best-fit model spectrum. The median value of beta evolves significantly from -1.82 (+0.00,-0.04) at z = 4, to -2.37 (+0.26,-0.06) at z = 7. Additionally, we find that faint galaxies at z = 7 have beta = -2.68 (+0.39,-0.24) (~ -2.4 after correcting for observational bias); this is redder than previous claims in the literature, and does not require "exotic" stellar populations to explain their colors. This evolution can be explained by an increase in dust extinction, with the timescale consistent with low-mass AGB stars forming the bulk of the dust. We find no significant (< 2-sigma) correlation between beta and M_UV when measuring M_UV at a consistent rest-frame wavelength of 1500 A. This is particularly true at bright magnitudes, though our results do show evidence for a weak correlation at faint magnitudes when galaxies in the HUDF are considered separately, hinting that dynamic range in sample luminosities may play a role. We do find a strong correlation between beta and the stellar mass at all redshifts, in that more massive galaxies exhibit redder colors. The most massive galaxies in our sample have red colors at each redshift, implying that dust can build up quickly in massive galaxies, and that feedback is likely removing dust from low-mass galaxies at z > 7. Thus the stellar-mass - metallicity relation, previously observed up to z ~ 3, may extend out to z = 7 - 8.

description: Bestäubung ist eine zentrale Ökosystemdienstleistung in der Landwirtschaft und daher ist es von großer Bedeutung Bestäuber zu schützen. Während die landwirtschaftliche Produktion von Bestäubern profitiert, können sich ihre Praktiken negativ auf lokaler und landschaftlicher Ebene auf diese auswirken. In dieser Arbeit zeige ich, dass gleichzeitig-blühende Kulturen die Zusammensetzung von Bestäubergemeinschaften verändern können. Honigbienen werden aus Apfelplantagen zu Rapsfeldern gelockt. Wildbienen hingegen bleiben in den Apfelanlagen. Landwirte können Wildbienen durch Nistmaterial fördern, welche synergetisch mit Honigbienen den Fruchtansatz erhöhen. Viele Insekten können als Bestäuber gemanagt werden, aber Risiken sollten berücksichtigt werden. Um Bestäubung in die Betriebsführung zu integrieren, benötigt es aber die Bereitschaft der Landwirte. Ich zeige, dass die Entscheidungsfindung von Landwirten von externen Faktoren, sowie ihrer Wahrnehmung von Bestäubern beeinflusst wird.
description: Pollination is a key ecosystem service in agricultural systems. Therefore, it is of major importance to conserve insect pollinators to sustain productivity. While agriculture is benefiting from the services pollinators provide, its practices on local and landscape scale are affecting pollinator abundances and foraging decision. In this thesis, I show that co-blooming crops can alter the pollinator composition as honey bees are drawn away from apple orchards to oilseed rape fields. Wild bee populations remain stable, possibly ensuring pollination. Wild bees can be promoted by installing nesting material, but enhance fruit set only synergistically with honey bees. I can show that many insect species can be managed, but risks should be considered. Finally, integrating pollination into farm management needs the willingness of farmers. I can show that farmers decision-making is affected by external factors and their perception of pollinators, which mainly influenced by on-farm experiences.

description: Gefäßprothesen finden in der Chirurgie häufig Anwendung als Gefäßersatz. Eine gefürchtete postoperative Komplikation stellt die Infektion dieser dar. Zum möglichen Erregerspektrum zählt auch der dimorphe Pilz Candida albicans. Die antimikrobielle Wirkung von Silber ist seit langem bekannt. Es wird deshalb auch als Beschichtung in Gefäßprothesen eingesetzt. Diese Silber-Kollagen-Prothesen werden zur Prävention oder Sanierung einer Infektion als Gefäßersatz implantiert. Die vorliegende Arbeit erforschte die Wirkung der Silber-beschichteten Prothese auf die Adhäsion und Biofilmbildung von Candida alibcans in unterschiedlichen Medien in vitro. Es kamen dabei verschiedene quantitative und bildgebende Verfahren zum Einsatz. Es zeigte sich, dass in RPMI-Medium die von der Silber-Prothese freigesetzten Ionen wirksam gegen eine Adhäsion und nachfolgende Biofilmbildung von Candida albicans waren. Nach Hinzugabe von fetalem Kälberserum zur Annäherung an physiologische Bedingungen konnte ein paradoxer Effekt der vermehrten Adhäsion und Biofilminduktion im Vergleich zu einer gleichartigen Kollagenprothese ohne Silberbeschichtung beobachtet werden. Wir postulierten anhand unserer weiteren Versuche, dass dies durch subinhibitorische Konzentrationen von Silberionen bedingt war.

description: We present shared representative filtering for real-time high-resolution depth completion with RGB-D sensors. Conventional filtering-based methods face a dilemma when the missing regions of the depth map are large. When the filter window is small, the filter fails to include enough samples. On the other hand, when the window is large, the method could oversmooth depth boundaries due to the error introduced by the extra samples. Our method adapts the filter kernels to the shape of the missing regions to collect a sufficient number of samples while avoiding oversmoothing. We collect depth samples by searching for a small set of similar pixels, which we call the representatives, using an efficient line search algorithm. We then combine the representatives using a joint bilateral weight. Experiments show that our method can filter a high-resolution depth map within a few milliseconds while outperforming previous filtering-based methods on both real-world and synthetic data in terms of both efficiency and accuracy, especially when dealing with large missing regions in depth maps.

Material examined.
• 1 pharate adult – male, Lake Gargalau 3 (R 5), 6 July 2023.
Distribution.
Palaearctic. The species was recorded only from a few countries in West and North Europe, but also from the Far East of Russia (Ashe and O’Connor 2009).
Habitat.
The ecological requirements of this species are not sufficiently known because of the problematic identification of the pre-imaginal stages. Generally, larvae inhabit stagnant waters, they are resistant to low pH values (Murray and Baars 2006; Perova 2008; Baars et al. 2014) and salinity (Kawai et al. 2000).
Remarks.
An adult male with associated exuviae confirms the presence of the species in Romania.

description: CTLA-4 spielt als immunmodulatorischer Korezeptor von T-Zellen eine zentrale Rolle in der Therapie maligner und autoimmuner Erkrankungen. Es ist bekannt, dass CTLA-4 neben der T-Zell-Aktivierung auch selektiv die Differenzierung von CD8+ Tc1-Zellen kontrolliert, indem zentrale Tc1-Faktoren wie Eomes, IFN-γ und Granzyme B inhibiert und die Zytotoxizität vermindert werden. Die Bedeutung von CTLA-4 für CD8+ Tc17-Zellen war bisher unbekannt. Zusammengefasst konnte in der vorliegenden Arbeit erstmalig gezeigt werden, dass CTLA-4-vermittelte Signale die Tc17-Differenzierung zellintrinsisch unterstützten und so eine erhöhte Tc17-Qualität vermittelten. Dieser Effekt war von einer erhöhten Expression des zentralen Tc17-Transkriptionsfaktors RORγt sowie weiterer Tc17-fördernder Faktoren begleitet und mit einer erhöhten Stabilität des Tc17-Phänotyps sowohl in-vitro als auch in- vivo assoziiert. CTLA-4-defiziente Tc17-Zellen zeigten im Vergleich zu CTLA-4+/+ Tc17-Zellen eine erniedrigte Expression von Tc17-Transkriptionsfaktoren, eine gesteigerte Plastizität und folglich eine erhöhte Zytotoxizität in-vivo und in-vitro. In einem Listeria monocytogenes-Infektionsmodell zeigten CTLA-4-/- Tc17-Zellen eine verstärkte Konversion in einen Tc1-ähnlichen Phänotyp mit hoher LM- Immunität, die mit Tc1-Zellen vergleichbar und mit erhöhten Anzahlen an polyfunktionalen IFN- γ+/TNF-α+ CD8+ T-Zellen assoziiert war. Die in dieser Arbeit gewonnenen Erkenntnisse erweitern das Wissen über die Bedeutung CTLA-4s für die T-Zell-Differenzierung. Sie könnten bei der iatrogenen Beeinflussung CTLA-4s im Rahmen der Therapie maligner Erkrankungen (z.B. durch anti-CTLA-4) helfen, das Verständnis zugrundeliegender Wirkmechanismen und Therapieerfolge zu steigern.

Ray tracing

description: Recent work by Bitterli et al. [BWP*20] introduced a real-time, many-light algorithm for rendering dynamic direct illumination from millions of lights by iteratively applying resampled importance sampling using weighted reservoir sampling. While enabling new levels of lighting complexity in real-time, the total cost remained beyond the budgets of even the most computationally demanding games. We introduce key algorithmic improvements developed while productizing this method that collectively reduce lighting costs by up to 7x, dramatically improve memory coherence, shrink the required ray budget, increase rendering quality, and expose parameters that enable trading quality for performance.

description: We propose a new reduced model for gravity-driven free-surface flows of shallow elastic fluids. It is obtained by an asymptotic expansion of the upper-convected Maxwell model for elastic fluids. The viscosity is assumed small (of order epsilon, the aspect ratio of the thin layer of fluid), but the relaxation time is kept finite. Additionally to the classical layer depth and velocity in shallow models, our system describes also the evolution of two scalar stresses. It has an intrinsic energy equation. The mathematical properties of the model are established, an important feature being the non-convexity of the physically relevant energy with respect to conservative variables, but the convexity with respect to the physically relevant pseudo-conservative variables. Numerical illustrations are given, based on a suitable well-balanced finite-volume discretization involving an approximate Riemann solver.

description: We investigate the geometric picture of the level surfaces of quantum entanglement and geometric measure of quantum discord (GMQD) of a class of X-states, respectively. This pictorial approach provides us a direct understanding of the structure of entanglement and GMQD. The dynamic evolution of GMQD under two typical kinds of quantum decoherence channels is also investigated. It is shown that there exists a class of initial states for which the GMQD is not destroyed by decoherence in a finite time interval. Furthermore, we establish a factorization law between the initial and final GMQD, which allows us to infer the evolution of entanglement under the influences of the environment.
