description: Indirect calorimetry and nitrogen excretion measurements allow quantifying dynamic changes in the rates of carbohydrate, lipid and protein oxidation over time. Although measuring oxygen consumption and carbon dioxide production is relatively simple, only a few studies presented these two measurements in avian models, but none used the data to calculate rates of metabolic fuel oxidation. Therefore, the first goal of this study was to use indirect calorimetry and nitrogen excretion measurements to quantify the rates of lipid, carbohydrate and protein oxidation over time in ruff sandpiper during cold exposure and terrestrial locomotion. Even though the data obtained does not allow me to test these hypotheses, one finding is really interesting. The ruff sandpiper may use intramuscular lipid reserves to power muscle contractions, but these small reserves would probably be depleted within a short period of time, especially during flight. Therefore, this species may have the capacity to use a secondary mechanism to carry lipids from the adipocytes to the working muscles. Because plasma albumin is present in limited amounts, and because each albumin molecule can only bind a limited number of fatty acids, VLDL-TAG from the liver may be a good way to insure that the working muscles do not run out of fuel.

description: Recent work suggests that music recommender systems are prone to disproportionally frequent recommendations of music from countries more prominently represented in the training data, notably the US. However, it remains unclear to what extent feedback loops in music recommendation influence the dynamics of such imbalance. In this work, we investigate the dynamics of representation of local (i.e., country-specific) and US-produced music in user profiles and recommendations. To this end, we conduct a feedback loop simulation study using the standardized LFM-2b dataset. The results suggest that most of the investigated recommendation models decrease the proportion of music from local artists in their recommendations. Furthermore, we find that models preserving average proportions of US and local music do not necessarily provide country-calibrated recommendations. We also look into popularity calibration and, surprisingly, find that the most popularity-calibrated model in our study (ItemKNN) provides the least country-calibrated recommendations. In addition, users from less represented countries (e.g., Finland) are, in the long term, most affected by the under-representation of their local music in recommendations.

Wormhole attack detection in wireless ad hoc networks
Creators: name: Gorlatova, Maria A
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis deals with wormhole attack discovery in mobile wireless ad hoc networks. Two separate approaches to wormhole attack discovery are developed in this thesis. One approach -- based on protocol-breaking -- allows detection of wormholes that disrupt network operations by dropping network packets. Another -- a novel frequency-based analysis of periodic network messages -- detects wormholes that do not drop traffic. The developed wormhole attack discovery techniques are local, do not rely on specialized hardware or clock synchronization, and do not require modification to existing ad hoc network routing protocols. In addition, tools that are necessary for ad hoc network attack research are created. Network traffic analyzer modules applicable to ad hoc network research are developed and tested. Also, a realistic implementation of a wormhole attack in the NS-2 network simulator is created.

description: A set of multipartite orthogonal states is genuinely nonlocal if it is locally indistinguishable in every bipartition of the subsystems. If the set is locally reducible, we say it has genuine nonlocality of type \uppercase\expandafter{\romannumeral 1}. Otherwise, we say it has genuine nonlocality of type \uppercase\expandafter{\romannumeral 2}. Due to the complexity of the problem, the construction of genuinely nonlocal sets in general multipartite systems has not been completely solved so far. In this paper, we first provide a nonlocal set of product states in bipartite systems. We obtain a genuinely nonlocal set of type~\uppercase\expandafter{\romannumeral 1} without entanglement in general $n$-partite systems $\otimes^{n}_{i=1}\mathbb{C}^{d_{i}}$ $[3\leq (d_{1}-1)\leq d_{2}\leq \cdots\leq d_{n},n\geq3]$. Then we present two constructions with genuine nonlocality of type~\uppercase\expandafter{\romannumeral 2} in $\mathbb{C}^{d_{1}}\otimes\mathbb{C}^{d_{2}}\otimes\mathbb{C}^{d_{3}}$ $(3\leq d_{1}\leq d_{2}\leq d_{3})$ and $\otimes^{n}_{i=1}\mathbb{C}^{d_{i}}$ $(3\leq d_{1}\leq d_{2}\leq \cdots\leq d_{n},n\geq4)$. Our results further positively answer the open problem that there does exist a genuinely nonlocal set of type~\uppercase\expandafter{\romannumeral2} in multipartite systems [M. S. Li, Y. L. Wang, F. Shi, and M. H. Yung, J. Phys. A: Math. Theor. 54, 445301 (2021)] and highlight its related applications in quantum information processing.

Path generation for filament winding of asymmetric fibre composite components.
Creators: name: Bernard, Étienne.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1991
Subjects: subject: Engineering, Mechanical.

description: This thesis describes several fibre path prediction techniques used for filament winding of continuous fibre composite components. A literature review dealing with different aspects of CAD/CAM related to filament winding is provided. The insight gained through the review is used in the selection of specific path prediction techniques for two types of components. The mathematical technique is selected for surfaces of revolution while a geometric approach based on flat triangular patches is chosen for general asymmetric shapes. Since it can be used for a wider variety of components, this latter technique, along with the critical parameters affecting its performance, is described in greater detail. Three factors are shown to directly affect the accuracy of the predicted path. They are the starting condition, the separation distance between the actual surface and the triangle approximation and finally, the local curvature of the surface in the direction of the fibre path. A general discussion on the structure of the filament winding CAD environment in terms of hardware and software is also given.
ML-empowered combinatorial search
Creators: name: Cameron, Christopher
Publisher: name: University of British Columbia
Year: 2025

description: Combinatorial search problems underlie a wide range of computational tasks, from resource allocation in 5G networks and spectrum auctions to verification of hardware and software systems. Despite the best-known techniques having worst-case exponential complexity, many real-world instances exhibit rich structural patterns that specialized solvers can exploit. No single solver excels across all problem distributions, and tuning solvers to specific distributions is crucial for best performance. When done by hand, this application-specific algorithm-design process is very tedious and limited. This thesis explores how machine learning (ML) can empower combinatorial search by integrating data-driven methods with symbolic solvers, maintaining correctness guarantees while adapting to specific applications. We begin by exploring evaluation and applications of two classic ML approaches for algorithm design: algorithm selection and configuration. We later relax two limitations of these classic approaches: (1) reliance on hand-crafted features to represent problem instances; and (2) a black-box view of one or more solvers. We relax the first constraint by learning an end-to-end neural representation of problem instances that captures the right invariances for reasoning about Boolean logic. We relax the second constraint by integrating ML into the solver’s internal decisions, proposing a new reinforcement learning approach, Monte Carlo Forest Search (MCFS), to learn improved branching policies in tree search. With these new advances, learning models for each new application typically demands extensive training data. We show it is possible to train foundation models that dramatically reduce the overhead of learning new tasks and distributions. We trained a single model on a large dataset across a broad range of combinatorial tasks that generalized both on held-out tasks and distributions. We found that models fine-tuned from the foundation models were substantially more sample efficient than models trained from scratch. Finally, we consider the predict-then-optimize paradigm, showing that coupling predictive models with the solver objective can prevent large degradations in solution quality. We formalize this in the setting where forecasts are inherently stochastic and multiple correlated forecasts drive downstream decisions.

description: PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/infrared telescope to be located at Dome C on the Antarctic plateau. The atmospheric conditions at Dome C deliver a high sensitivity, high photometric precision, wide-field, high spatial resolution, and high-cadence imaging capability to the PILOT telescope. These capabilities enable a unique scientific potential for PILOT, which is addressed in this series of papers. The current paper presents a series of projects dealing with the distant (redshift > 1) Universe, that have been identified as key science drivers for the PILOT facility. The potential for PILOT to detect the first populations of stars to form in the early Universe, via infrared projects searching for pair-instability supernovae and gamma-ray burst afterglows, is investigated. Two projects are proposed to examine the assembly and evolution of structure in the Universe: an infrared survey searching for the first evolved galaxies at high redshift, and an optical survey aimed at characterising moderate-redshift galaxy clusters. Finally, a large-area weak-lensing survey and a program to obtain supernova infrared light-curves are proposed to examine the nature and evolution of dark energy and dark matter.

description: The EU-based COST-Program supports topic-related scientific networks with financial resources. Such programs allow especially researches from countries with comparably low socio-economic status or low research capacities to participate in important network activities. The European Burden of Disease Network is part of the COST-Program and with 38 countries it is one of the biggest currently running COST-Actions. The interest for Burden of Disease (BoD) in Europe is growing at a high pace and more an more countries use BoD estimates in public health policy decision making processes. Thus, the aim of the network is to make researchers familiar with BoD and to harmonize currently used methods. The activities of the network are structured in five complementary working groups.

Fibroblast growth factor 8 and cell proliferation in zebrafish fins.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Biology, Molecular.

description: The fins of some teleost fishes, like many urodele amphibian limbs, have the ability to regenerate after injury. This regeneration process occurs in a sequential manner beginning with the closure of the wound by epithelial cells and followed by the establishment of a region of undifferentiated proliferating mesenchymal cells called the blastema. To examine the pattern of cell proliferation taking place in the different tissues during the regeneration process of zebrafish (Danio rerio) caudal fins, I followed the pattern of incorporation of bromodeoxyuridine (BrdU) in the DNA of proliferating cells at various times after amputation. Growing evidence suggests that key molecules involved in signaling pathways leading to limb bud development are also acting during fin bud development. Some of these signals are members of the fibroblast growth factor (Fgf) gene family which locally regulate growth and patterning in vertebrate embryos and during limb regeneration. I sequenced a cDNA clone encoding for the zebrafish FGF8 protein and analyzed its pattern of expression during zebrafish embryonic development and during fin regeneration.

Year: 2024

description: This thesis uses molecular dynamics (MD) simulations to investigate the Kapitza resistance in nano-confined fluids using molecular dynamics (MD) simulations. A method based on linear response theory, which follows a fundamental approach in statistical mechanics, has been developed to calculate the Kapitza resistance in solid-fluid interfaces with the help of equilibrium MD simulations. The proposed method is used to study the molecular-level mechanisms of interfacial heat transfer and various factors affecting the Kapitza resistance. The present study provides a clear understanding of the molecular level mechanism of interfacial heat transfer in various solid-fluid interfaces.
The Hybrid Mineral Battery : energy storage and dissolution behavior of CuFeS₂ in a fixed bed flow cell

Publisher: name: ChemSusChem

description: The development of a hybrid system, capable of storing energy, and with the additional benefit of Cu extraction is discussed in this work. A fixed bed flow cell (FBFC) was used in which a composite negative electrode containing CuFeS₂ (80 wt. %) and carbon black (20 wt. %) in graphite felt was separated from a positive (graphite felt) electrode by proton exchange membrane. The anolyte (0.2M H₂SO₄) and catholyte (0.5M Fe²⁺ in 0.2M H₂SO₄ with or without 0.1M Cu²⁺ addition) were circulated in the cell. With the addition of Cu²⁺ in the catholyte, the electrochemical activity of the Fe²⁺/Fe³⁺ redox couple over graphite felt was significantly improved. Ultimately, in the CuFeS₂||Fe²⁺/Cu²⁺ (CFeCu) FBFC system the specific capacity increased continuously to 26.4 mAh g-¹ in 500 galvanostatic charge/discharge (GCD) cycles, compared to the CuFeS₂||Fe²⁺ (CFe) system (13.9 mAh g-¹). Interestingly, the specific discharge energy gradually increased to 3.6 Wh kg-¹ in 500 GCD cycles for the CFeCu system compared to 3.29 Wh kg-¹ for the CFe system in 150 cycles. In addition to the energy storage, 10.75 % Cu was also extracted from the mineral, which is an important feature of CFeCu system as it would allow for Cu extraction and recovery through hydrometallurgical methods.
The effect of detachment sliding on surface wash erosion in the continuous permafrost zone, Hot Weather Creek, Fosheim Peninsula, Ellesmere Island, Northwest Territories.

description: An experimental design was developed to evaluate the effect of active-layer detachment sliding on surface wash erosion. Specifically, the aim was to examine to what extent the disturbance of vegetation cover, changes in hydrological conditions due to topographic modification by detachment sliding and the formation of a fresh active layer affect rates of surface wash erosion. Detachment slides generally accumulated more snow than adjacent slopes and yielded greater amounts of surface runoff than vegetated slopes with similar snow covers. Surface drainage was inhibited on well-vegetated hummocky slopes where lags between radiation inputs and discharge responses were greater than at the rilled detachment slide plots. During rainfall events following snowmelt, plot response was affected by antecedent moisture conditions and the vegetation cover: surface flow was generated only in detachment slide scars and at the mixed plots but not on vegetated undisturbed slopes or on the bare undisturbed slope. Suspended sediment concentrations at the fresh detachment slide scars are two orders of magnitude greater than on vegetated slopes. Greater amounts of surface runoff production at fresh scars and the removal of vegetation result in high rates of surface erosion and high sediment yields (1560 g/m$\sp2)$ at fresh detachment slide scars.

Causal collaborative filtering

Year: 2024

description: In the era of information explosion, recommender systems have become crucial tools for fulfilling users' personalized and complex demands, finding widespread application in various real-world services such as e-commerce, job seeking, and social media. Collaborative filtering algorithms, among others, are fundamental algorithms that support the underlying mechanism of recommender systems. In general, collaborative filtering algorithms leverage similarities between users and items to provide recommendations. The intuition is that similar users should share similar tastes, and similar items may be liked by similar users. Traditional collaborative filtering methods, including memory-based methods such as user/item-based CF as well as learning-based methods such as matrix factorization and deep learning models, primarily focus on focus on mining or learning correlative patterns from data for matching. However, many real-world applications are driven by underlying causal mechanisms, and reliance solely on correlative learning can lead to practical issues such as Simpson's paradox, confounding bias, and echo chambers. To address these challenges, this dissertation introduces a set of causal collaborative filtering methods based on the structural causal model (SCM) framework. These methods aim to advance from correlative learning to causal learning by formulating the essence of recommender systems as a "what if" question: what would happen if we recommend a certain item to a target user? This question is answered by causal preference using the $do$-operator. By constructing causal graphs and applying causal inference techniques, these methods estimate causal preferences, offering a novel approach to collaborative filtering. The dissertation presents causal collaborative filtering methods that address various issues in recommender systems through different types of causal graphs and inference techniques. It begins with mitigating Simpson's paradox using conditional intervention on directed acyclic graphs. Subsequently, it tackles unobserved confounders by incorporating unobserved variables into the causal graph and employing front-door adjustment. Finally, it addresses the challenge of echo chambers by modeling the dynamic and iterative process of recommender systems with loops in causal graphs and applying the back-door adjustment method. This comprehensive approach provides a significant advancement in the field of recommender systems by integrating causal learning into collaborative filtering methods.
Effects of ICT Investment and Usage on Economic Growth in MENA Countries: Does Governance Matter?

Year: 2024

description: This study examines the impact of ICT usage and investment on economic growth in 16 MENA countries from 1995 to 2018. Furthermore, this study examines how national governance affects the relationship between ICT usage, investment, and economic growth. Using the panel ARDL method, the results show that ICT usage contributes significantly to higher economic growth, but ICT investment has no direct impact. We also find that better governance increases the impact of ICT usage and investment on economic growth. This study’s findings are critical for policymakers seeking to improve ICT's contribution to economic growth.

description: A psychosis phenotype can be observed below the threshold of clinical detection. The study aimed to investigate whether subclinical psychotic symptoms are associated with deficits in controlling emotional interference, and whether cortical brain and cardiac correlates of these deficits can be detected using functional near-infrared spectroscopy (fNIRS). A data set derived from a community sample was obtained from the Zurich Program for Sustainable Development of Mental Health Services. 174 subjects (mean age 29.67 ± 6.41, 91 females) were assigned to four groups ranging from low to high levels of subclinical psychotic symptoms (derived from the Symptom Checklist-90-R). Emotional interference was assessed using the emotional Stroop task comprising neutral, positive, and negative conditions. Statistical distributional methods based on delta plots [behavioral response time (RT) data] and quantile analysis (fNIRS data) were applied to evaluate the emotional interference effects. Results showed that both interference effects and disorder-specific (i.e., group-specific) effects could be detected, based on behavioral RTs, cortical hemodynamic signals (brain correlates), and heart rate variability (cardiac correlates). Subjects with high compared to low subclinical psychotic symptoms revealed significantly reduced amplitudes in dorsolateral prefrontal cortices (interference effect, p < 0.001) and middle temporal gyrus (disorder-specific group effect, p < 0.001), supported by behavioral and heart rate results. The present findings indicate that distributional analyses methods can support the detection of emotional interference effects in the emotional Stroop. The results suggested that subjects with high subclinical psychosis exhibit enhanced emotional interference effects. Based on these observations, subclinical psychosis may therefore prove to represent a valid extension of the clinical psychosis phenotype.

description: Die tiefe Geothermie birgt in Deutschland keine unbeherrschbaren Risiken für die Umwelt. Das ist das Ergebnis einer Studie, die die Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) erstellt hat. Die tiefe Geothermie setzt  meist erst unterhalb von 2.000 Metern an. Dort herrschen Temperaturen von mehr als 60 Grad Celsius. Um diese Erdwärme zu nutzen, kann es manchmal nötig sein, Wasser mit hohem Druck in die dortigen Gesteinsschichten zu pressen. Damit werden Fließwege für die spätere Wasserzirkulation des Geothermie-Kraftwerkes geschaffen. Bei dieser Methode kommen keine wassergefährdenden Zusätze zum Einsatz. Lediglich in Kalkstein werden gegebenenfalls verdünnte Säuren umweltverträglich eingesetzt. Schäden durch seismische Ereignisse sind bei kontrolliertem Vorgehen nicht zu befürchten.

From metabolic scaling to metacommunities : conceptual and empirical advances in community thermal ecology
Creators: name: Stark, Keila
Publisher: name: University of British Columbia
Year: 2025

description: Ecologists face the challenge of understanding and predicting how living systems change as thermal regimes change relative to historical norms. To meet this challenge, we require theories that relate temperature change to biological processes influencing biodiversity patterns across levels of organization, from individual organisms to whole ecosystems. Ecological and evolutionary responses to temperature are mediated by its effects on organism growth, survival, reproduction, and other components of fitness, all governed by metabolism. In this thesis, I draw from concepts in metabolic scaling theory and metacommunity theory to better understand and predict how biodiversity and functioning in ecological communities respond to warming. First, I review key concepts in the Metabolic Theory of Ecology (MTE), including its assumptions of steady state conditions in its original models of temperature-dependent biological processes. I suggest extensions to MTE that better capture ecological systems frequently disrupted from steady state under climate change, including transient population dynamics and evolving thermal response curves. Next, using a freshwater mesocosm experiment, I test whether dispersal modifies the temperature dependence of community metabolism. While gross primary productivity and community respiration increase with temperature and biomass, dispersal does not significantly alter their temperature dependence. Instead, successional dynamics drive variation in community metabolism, highlighting the need to account for these dynamics in metabolic theory models. I then develop a temperature-dependent metacommunity model to simulate how warming-driven changes in growth, competition, and dispersal change species richness and abundance. I show that including temperature-dependent competition and dispersal fundamentally alters predictions compared to conventional models, and whether diversity and abundance increase or decrease per degree warming depends on community competition structure and differences in species' thermal response curves. Last, I experimentally estimate thermal response curves for population dispersal rates. I find species-specific thermal response curves for dispersal which differ from those for growth rates; these differences result in different colonization dynamics and regional biodiversity patterns across temperatures. Together, these studies link the conserved temperature dependence of metabolism with the diversity of thermal phenotypes among organisms and resulting biodiversity patterns across space and time.

Telecommunications prices in Australia - the last twenty years
Creators: name: Luck, David

description: The late 1980s saw a transformation of telecommunications in Australia with the introduction of limited competition. In 1997 the market was fully opened to competition. It was hoped on both these occasions that competition would lead to low prices and a wide range of services. The resulting picture has been mixed. Prices have fallen significantly but Australia is not at the forefront of low international prices. However, there are a number of reasons for this and it is unrealistic to expect very low prices. Australian consumers and businesses have benefitted greatly from the large reductions in prices that have occurred and price reductions are undoubtedly a key reason for the growing importance of telecommunications in household and business budgets and our lives generally over the past twenty years.

description: Die EU-Chemikalienverordnung REACH gibt Verbraucherinnen und Verbrauchern das Recht auf Auskunft über sogenannte besonders besorgniserregende Stoffe in Produkten. Der Haken daran: Es muss erst eine Anfrage an Hersteller oder Händler gestellt werden. Die App Scan4Chem des Umweltbundesamtes (UBA) vereinfacht diese Anfrage. Die App wurde nun komplett überarbeitet. Was ist neu? Sie ist an eine neue europäische Datenbank angeschlossen, in die Hersteller und Händler ihre Informationen eintragen können. Außerdem wird die App nun in 14 europäischen Staaten angeboten. Je mehr Verbraucherinnen und Verbraucher die App nutzen, desto eher werden Hersteller und Lieferanten ihre Daten in die neue Datenbank eintragen. Und die Informationen aus der Datenbank stehen allen zur Verfügung: sofort, per Klick über die App. Je öfter die App genutzt wird, desto besser wird sie! Je mehr Menschen Anfragen stellen, desto eher werden Hersteller kritische Chemikalien in ihren Produkten ersetzen.

description: The EU Chemicals Regulation REACH entitles you to receive information on so-called substances of very high concern in consumer articles. The catch is that you first have to send an information request to the manufacturer or retailer. The Scan4Chem app of the German Federal Environment Agency simplifies this request for you. The app has now been completely revised. Whatââą Ìs new? It is connected to a new European database in which manufacturers and retailers can enter their information. In addition, the app is now available in 14 European countries. The more consumers use the app, the sooner manufacturers and retailers will enter their data in the new database. And the information from the database is available to everyone: immediately, by clicking in the app. The more often you use the app, the better it will be! The more people send request, the more likely manufacturers are motivated to replace critical chemicals in their products.

description: Im Rahmen der Berichtspflicht über das Elektro(nik)geräte und -altgeräteaufkommen in Deutschland erfolgte im vorliegenden Bericht die Analyse und Aggregation der Daten der stiftung ear und des Statistischen Bundesamtes (Destatis) für das Jahr 2015. Insgesamt brachten Hersteller 1,9 Millionen Tonnen Elektro(nik)geräte (b2b+b2c) auf den Markt – der höchste Wert seit Beginn der Dokumentation im Jahr 2006. Die ermittelten Daten über zurückgenommene und behandelte Mengen an Altgeräten zeigen, dass Deutschland fast alle festgelegten Ziele und Quoten erfüllt, außer bei Kategorie 5a (Gasentladungslampen), bei der die vorgesehene Recyclingquote von 80 % mit 77,23 % nicht erreicht wurde.
Minding the gap(s) in Australian spectrum law
Creators: name: Freyens, Benoit Pierre
Publisher: name: Swinburne
Year: 2024

description: Achieving efficient spectrum management in the pursuit of the public interest was a key aspect of the legislative reforms enacted through the Radiocommunications Act 1992. However, the Act is unclear about the precise nature of the efficiencies to achieve and choices between different efficiency objectives are often dictated by the nature of the services, bands and market considered. This article argues that efficient spectrum policy can be furthered by crafting additional licensing regimes or expanding the possibilities of existing regimes. Despite successes in moving towards this goal, some legal rules still feed a pool of 'licensing gaps' that detract from the public interest they are meant to serve. The article discusses remedies to these gaps.

description: Viele der Polyzyklischen Aromatischen Kohlenwasserstoffe (⁠PAK⁠) sind als krebserregend eingestuft und können in der Umwelt nur schwer abgebaut werden. Hauptemissionsquelle in die Luft sind Kleinfeuerungsanlagen, die mit Festbrennstoffen betrieben werden. In dem Projekt wurde untersucht, welche ⁠PAK⁠-Emissionen bei modernen Kaminöfen in der Anbrandphase und während der Hauptverbrennung entstehen können. Einige Öfen wurden sowohl mit Holz als auch mit Braunkohlenbriketts beheizt, um herauszufinden inwieweit sich der Brennstoff auf die Emissionshöhe der einzelnen PAK auswirkt. Der Bericht enthält eine Beschreibung der Verbrennungsbedingungen, die Darlegung des Messverfahrens sowie die Messergebnisse für die 16 PAK nach US EPA. Der ebenfalls veröffentlichte Factsheet enthält Messwerte zusätzlicher Schadstoffe, die an den gleichen Kaminöfen gemessen wurden.

description: Continuous flash suppression (CFS) is an interocular suppression technique that uses high-contrast masks flashed to one eye to prevent conscious perception of images shown to the other eye. It has become widely used due to its strength and prolonged duration of suppression and its nearly deterministic control of suppression onset and offset. Recently, it has been proposed that action-relevant visual processing ascribed to the dorsal stream remains functional, while processing in the ventral stream is completely suppressed, when stimuli are invisible under CFS. Here we tested the hypothesis that the potentially dorsal-stream-based analysis of prime-stimulus elongation during CFS affects the categorization of manipulable target objects. In two behavioral experiments, we found evidence for priming in a shape task, but none for priming in a category task, when prime stimuli were rendered invisible using CFS. Our results thus support the notion that the representation of CF-suppressed stimuli is more limited than previously thought.
