description: Home networks must meet increasingly higher demands which will require the use of multiple communication media. Wireless and powerline communication (PLC) channels are a natural combination due to their ability to provide extensive in-home coverage. This thesis focuses on improving the performance of indoor communication links by using the wireless and PLC channels for diversity. This thesis makes a contribution in several areas related to wireless/PLC diversity communication. First, a low-cost architecture based on orthogonal frequency division multiplexing (OFDM) is presented and several optimum and suboptimum methods for received signal combining are developed. As the PLC channel contains impulsive noise, a low-complexity nonlinear combining technique based on a saturated Gaussian metric is proposed. Second, the actual characteristics of parallel wireless and PLC channels are measured in several detached homes. The measurements reveal that wireless and PLC signal-to-noise ratios (SNRs) have a wide range and are relatively uncorrelated. This leads to the conclusion that diversity can be of benefit in many home networking scenarios. Finally, the performance of optimum and suboptimum combining schemes is evalu­ated using theoretical analysis and channel measurement data. Results show that the saturated metric scheme performs well when PLC noise is highly impulsive and conven­tional linear combining schemes perform well when PLC noise is mildly impulsive. A Monte Carlo simulation of an OFDM communication link shows that the likelihood of low throughput links can be significantly reduced when wireless and PLC channels are used for diversity.

description: Einstein's General Relativity (GR) is a dynamical theory of the spacetime metric. We describe an approach in which GR becomes an SU(2) gauge theory. We start at the linearised level and show how a gauge theoretic Lagrangian for non-interacting massless spin two particles (gravitons) takes a much more simple and compact form than in the standard metric description. Moreover, in contrast to the GR situation, the gauge theory Lagrangian is convex. We then proceed with a formulation of the full non-linear theory. The equivalence to the metric-based GR holds only at the level of solutions of the field equations, that is, on-shell. The gauge-theoretic approach also makes it clear that GR is not the only interacting theory of massless spin two particles, in spite of the GR uniqueness theorems available in the metric description. Thus, there is an inifnite-parameter class of gravity theories all describing just two propagating polarisations of the graviton. We describe how matter can be coupled to gravity in this formulation and, in particular, how both the gravity and Yang-Mills arise as sectors of a general diffeomorphism invariant gauge theory. We finish by outlining a possible scenario of the UV completion of quantum gravity within this approach.

description: In this study, we showed that Tumorous Imaginal Disc 1 (Tidl) has the ability to indirectly modulate p53 ubiquitination in breast cancer cells. The over-expression of Tidl expression in MCF-7 cells led to suppression of p53 ubiquitination whereas its suppression led to enhanced ubiquitination. Tid 1 mediated suppression of p53 ubiquitination can enhance p53 half-life but not endogenous p53 level or p53 downstream targets. Over-expression of Tidl alone was unable to decrease the cell viability of MCF-7 cells but its combination with the proteasome inhibitor ALLN, there was a decrease in cell viability. A reduction in ATP level by Tidl over-expression is suggested to be one of the possible mechanisms that may suppress p53 ubiqutination. In summary, we propose that Tid 1 depletes cellular ATP levels, which in tum, inhibits ubiquitination­proteasome machinery, resulting in enhanced stability of p53.

description: The ability to infer the reactor flux from spent fuel or seized fissile material would enhance the tools of nuclear forensics and nuclear nonproliferation significantly. We show that reactor flux can be inferred from the ratios of xenon-136 to xenon-134 and cesium-135 to cesium-137. If the average flux of a reactor is known, the flux inferred from measurements of spent fuel could help determine whether that spent fuel was loaded as a blanket or close to the mid-plane of the reactor. The cesium ratio also provides information on reactor shutdowns during the irradiation of fuel, which could prove valuable for identifying the reactor in question through comparisons with satellite reactor heat monitoring data. We derive analytic expressions for these correlations and compare them to experimental data and to detailed reactor burn simulations. The enrichment of the original uranium fuel affects the correlations by up to 3 percent, but only at high flux.

description: This paper discusses an instructional strategy which explores eventual similarities and/or analogies between familiar problems and more sophisticated systems. In this context, the Atwood's machine problem is used to introduce students to more complex problems involving ropes and chains. The methodology proposed helps students to develop the ability needed to apply relevant concepts in situations not previously encountered. The pedagogical advantages are relevant for both secondary and high school students, showing that, through adequate examples, the question of the validity of Newton's second law may be introduced to even beginning students.

description: A gate electric field has a small but non-negligible effect on the phase of the valley-orbit coupling in Si quantum dots. Finite interdot tunneling between valley eigenstates in a double quantum dot is enabled by a small difference in the phase of the valley-orbit coupling between the two dots, and it in turn allows controllable rotations of two-dot valley eigenstates at a level anticrossing. We present a comprehensive analytical discussion of this process, with estimates for realistic structures.

description: Capital investment in national infrastructure is significant. The need to maintain and protect critical infrastructure links has led in recent years to significant developments in the area of structural health monitoring. The objective is to track a structure’s long-term performance, typically using sensors, and to successively compare the most recently measured responses with prior response history. During construction of the West Street On-Ramp, a curved concrete box girder bridge, located in the city of Anaheim (California), eleven accelerometers were permanently installed on its bridge deck. The associated data acquisition system was configured to record once a specified threshold acceleration response was exceeded; during the period 2002–2010 a total of 1350 datasets including six earthquakes, for each of the eleven sensors, were acquired. This automatically acquired data was supplemented, during the summer of 2009, with responses measured during controlled vehicle tests. Six accelerometers were additionally installed on the frame of the weighed test vehicle. This paper presents the findings of the analyses of these measured data sets and serves to inform owners and managers as to the potential feedback from their instrumentation investment. All response histories were analyzed using frequency domain techniques for system identification. Extraction of the modal characteristics revealed a continuous reduction, of approximately 5%, in the first three natural frequencies over the period of the study. The measured responses from the vehicle sensors are discussed in the context of identifying the potential for bridge frequency measurement using instrumented vehicles.

description: The reservoir-wave approach provided the idea that systemic vascular resistance could be modeled as several component resistors arranged in series. The purpose of this investigation was to apply the reservoir-wave approach to the renal circulation and examine how a renal venous constriction (RVC) or a renal arterial infusion of vasoactive agents into one kidney altered conductance, P oo, and series resistances. Endothelin-1 and Angiotensin 11 reduced conductance to 39.6 ± 5.1 and 64.4 ± 4.3%; total renal resistance increased but arterial reservoir resistance decreased to 64.8 ± 6.3 and 80.0 ± 6.1 % of the control respectively. Endothelin-1 and Angiotensin II also increased Poo by 14.5 ± 2.7 and l 0.2 ± 3.6 mmHg, and the microcirculatory plus venous resistance to 187.2 ± 21.0 and 180.0 ± 35.8% ofthe control respectively. RVC increased conductance to I 12.3 ± 4.4% of the control, in apparent compensation. The reservoir-wave approach is applicable to the renal circulation and its use in subsequent investigations is warranted.

description: Private landowners in South Africa have, for decades, derived sustainable income from the use of indigenous biodiversity through ecotourism and hunting. These benefits provide incentives to conserve biodiversity and private landowners "protect" more than double the area of proclaimed protected areas and they contribute substantially to achievement of national conservation targets. Recent trends in wildlife ranching however include selective breeding of indigenous game species to produce extraordinary trophy animals based on either unusual colour variations or trophy quality. These animals are sold either as breeding stock or directly for trophy hunting. Breeding is generally done in intensive or semi-extensive environments to faciltate selective breeding and to reduce production risks. Financial returns on certain atypical wildlife species have been exceptionally high and they run the risk of becoming a financial commodity. Conservation agencies and certain groups within the wildlife industry have raised concerns about the potential negative impacts that this commercialisation of wildlife can have on biodiversity integrity and associated industries. Another view is however that these activities contribute to the development of a sustainable green economy. Mainstream sustainable development thinking dictates that activities only have a long-term value to humanity if their benefits continuously outweigh the social and environmental costs of generating that value. This paper discusses intensive and selective breeding of indigenous wildlife, in terms of economic, environmental and social sustainability to guide our thinking in a complex, multi-disciplinary reality in order to determine the benefits and/or risks to current and future generations as wildlife is a common heritage of the people of South Africa.

description: A particular compensation-type solution of the main cosmological constant problem has been proposed recently, with two massless vector fields dynamically canceling an arbitrary cosmological constant Λ. The naive expectation is that such a compensation mechanism does not allow for the existence of an inflationary phase in the very early Universe. However, it is shown that certain initial boundary conditions on the vector fields can in fact give rise to an inflationary phase.

description: We report ionization cross section measurements for electron impact single ionization (EISI) of Fe11+ forming Fe12+ and electron impact double ionization (EIDI) of Fe11+ forming Fe13+. The measurements cover the center-of-mass energy range from approximately 230 eV to 2300 eV. The experiment was performed using the heavy-ion storage ring TSR located at the Max-Planck-Institut für Kernphysik in Heidelberg, Germany. The storage ring approach allows nearly all metastable levels to relax to the ground state before data collection begins. We find that the cross section for single ionization is 30% smaller than was previously measured in a single-pass experiment using an ion beam with an unknown metastable fraction. We also find some significant differences between our experimental cross section for single ionization and recent distorted wave (DW) calculations. The DW Maxwellian EISI rate coefficient for Fe11+ forming Fe12+ may be underestimated by as much as 25% at temperatures for which Fe11+ is abundant in collisional ionization equilibrium. This is likely due to the absence of 3s excitation-autoionization (EA) in the calculations. However, a precise measurement of the cross section due to this EA channel was not possible because this process is not distinguishable experimentally from electron impact excitation of an n = 3 electron to levels of n ≥ 44 followed by field ionization in the charge state analyzer after the interaction region. Our experimental results also indicate that the EIDI cross section is dominated by the indirect process in which direct single ionization of an inner shell 2l electron is followed by autoionization, resulting in a net double ionization.
Towards supporting users in assessing the risk in privilege elevation
Creators: name: Motiee, Sara
Publisher: name: University of British Columbia
Year: 2011

description: To better protect users from security incidents, the principle of least privilege (PLP) requires that users and programs be granted the most restrictive set of privileges possible to perform the required tasks. The low-privileged user accounts (LUA) and privilege elevation prompts are two practical implementations of PLP in the main-stream operating systems. However, there is anecdotal evidence suggesting that users do not employ these implementations correctly. Our research goal was to understand users' challenges and behavior in using these mechanisms and improve them so that average users of personal computers can follow the PLP correctly. For this purpose, we conducted a user study and contextual interviews to investigate the understanding, behavior, and challenges users face when working with user accounts and the privilege elevation prompts (called User Account Control (UAC) prompts) in Windows Vista and 7. We found that 69% of participants did not use and respond correctly to UAC prompts. Also, all our 45 participants used an admin user account, and 91% were not aware of the benefits of low-privileged user accounts or the risks of high-privileged ones. Their knowledge and experience were limited to the restricted rights of low-privileged accounts. Based on our findings, we offered recommendations to improve the UAC and LUA approaches. Since our study showed that users can benefit from UAC prompts, we investigated the information content for such prompts so that users can assess the risk of privilege elevation more accurately and consequently respond to the prompts correctly. We considered thirteen different information items for including on these prompts mostly based on the results of our first study. Our user study with 48 participants showed that program name, origin, description, digital certification, changes the program applies and the result of program scan by anti-virus are the most understandable, useful and preferred items for users. To avoid habituation, decrease cognitive load on users and improve users' response to the prompts, we recommend to employ a context-based UAC prompt which presents a subset of information items to users based on the context. A set of guidelines is provided for selecting the appropriate items in different contexts.

description: Angular power spectra are calculated and presented for the entirety of the Canadian Galactic Plane Survey polarization dataset at 1.4 GHz. The data analyzed is a combination of data from the 100-m Effelsberg Telescope, the 26-m telescope at the Dominion Radio Astrophysical Observatory, and the Synthesis Telescope at the Dominion Radio Astrophysical Observatory, allowing all relevant scales to be sampled down to arcminute resolution. Calculated angular power spectra cover multipoles from ℓ ≈ 60 to ℓ ≈ 10⁴, and display at least three distinct regions within this range. A power-law region at low multipoles, a flattening region at intermediate multipoles, and a taper region at high multipoles necessitate a model fitting routine for analysis. Power-law indices are found to have a mode of 2.3, similar to other results, though slightly steeper. An increasing trend in power-law index is found with increasing latitude. A transition from small-scale to large-scale structure is evident at b = 10°. Flattening of the power spectra is also investigated and found to be likely due to background point sources, though this remains inconclusive.

Iconoclasm

description: This paper considers some aspects of the relation between historical conditions and theological arguments raised in the Iconoclastic controversy, with reference, in the main, to the work of the two major iconodule writers, John of Damascus (c. 675-749) and Theodore the Studite (759-826). The former who came from an aristocratic Byzantine family, wrote from Mar Saba monastery, near Bethlehem, in Arab lands that were outside imperial control; in Three apologies against those who cast down the icons1 he provided the most important systematic vindication of the iconodule position. Apart from being the most important of the Orthodox controversialists he is also the main figure (along with Patriarch Germanos) during the first stage of the iconoclastic controversy, which began with the accession of the Emperor Leo III the Isaurian in 717 and reached a first resolution in the Seventh Oecumenical Council's vindication of the iconodule position at Nicaea in 787, with the subsequent restoration of the great Icon of Christ Antiphonitis over the Bronze Gate to the Great Imperial Palace at Constantinople.

description: MYPTl has proven to be a key regulator in smooth muscle contraction and relaxation through the mechanisms of Ca2+ sensitization and desensitization. The regulation of MYPTl is controlled through the phosphorylation of several key residues. Kinase assays were carried out to confirm which amino acid residues of MYPT 1 were targeted by PKA and PKG in vitro. The following residues were then examined for functional significance in vitro and in situ with the use of recombinant proteins and RT A smooth muscle. From our studies we demonstrate the first direct evidence of in situ dual phosphorylation of MYPTl at Ser695/Thr696 and Ser852/Thr853. Also, that pre­phosphorylation of Ser852 by PKA/PKG has an inhibitory effect on the ability of ROK to phosphorylate the neighboring inhibitory residue of Thr853, similar to the effect previously observed for the Ser695/Thr696 region. Furthermore, the pre-phosphorylation ofThr696 by ROK decreased the ability of PKA/PKG to phosphorylate Ser695 in vitro and in situ.

description: In this paper four different methods are investigated for estimating the equivalent modal damping ratios of a short-span bridge under strong ground motion by considering the energy dissipation at the boundary. The Painter Street Overcrossing (PSO) is investigated because of seismic data availability. Computed responses using the response-spectrum method with the equivalent damping ratios estimates are compared with the recorded responses. The results show that the four methods provide reasonable estimation of equivalent modal damping ratios and that neglecting off-diagonal elements in the damping matrix is the most efficient and practical method. The equivalent damping ratio of the PSO was nearly 25% under an earthquake with peak ground acceleration of 0.55g, which is much higher than the conventional assumption of 5%.

description: Bibliography: p. 80-82
description: First, a low power imager with dual analog power supply 1.8V and 1.1 V during integration and readout stages is proposed. The supply voltage for each 8x8 block depends on the estimated variance within the block. The imager is more efficient for predominant-background pictures. According to simulation, up to 37% of power consumption can be saved while PSNR loss is less than 1.5 dB. Then, a low power CMOS imaging system with "smart" image capture and adaptive complexity 2D-DCT calculation is proposed. The DCT calculation has adaptive complexity according to block types estimated during image capture. The image sensor with block type decision circuit is implemented in TSMC 0.18 ?m technology. The adaptive complexity 2DDCT calculation is implemented based on Cyclone EP1C20F400C8 device. Up to 46% of the power can be saved during compression for predominant-background images, while no extra image quality degradation occurs comparing with traditional compressions.

description: Cadaver-decomposition unleashes an ephemeral pulse of matter input that modifies microbial communities, as well as nutrient pools and fluxes. This leaves behind a measurable imprint on affected soils. However, the persistence of this imprint remains poorly understood. We define cadaver imprint persistence as the entire period between time of cadaver deposition and time when cadaver effects on microbial community structure and chemical indicators are no longer detectable. We present a brief overview of published results on the cadaver-induced changes in the bio-elements carbon, nitrogen and phosphorus, which regulate the structure and functions of the soil microbiome. Based on this, we identified conceptual and methodological gaps and biases and suggest potential research avenues to address them. This will help to better understand the relationships between cadaver-derived matter and microbial taxa and functions, as well as the role of cadaver-decomposition within and across ecosystems. The proposed future research on cadaver-derived imprint on soils has the potential to serve as a hub for connecting soil chemistry, microbial ecology, forensic sciences, and ecosystems science.

In that time, the nation's 1,700 land trusts have helped landowners conserve more than 47 million acres of farm and ranch land, wildlife habitat, and open space around the country, including more than 1.2 million acres in Colorado. Financial incentives play a critical role in these efforts. This session will provide an overview of these incentives, including federal, state and local tax benefits available to conservation-minded landowners, as well as government and private funding options. This session is not intended to provide legal, financial or accounting advice. Rather, it will give participants a working knowledge of the financial incentives available for conservation in the United States, with a particular focus on Colorado.

In contrast to previous studies of this kind, the effects of the dipolar and quadrupolar interactions of the muon with nearby nuclei are calculated. ZF-muSR spectra with a high number of counts were also recorded to determine whether a magnetically ordered phase exists in dilute regions of the sample. Despite these efforts, we find no evidence for static magnetic order of any kind in the pseudogap region above the hole-doping concentration p = 0.13.

description: ER nurses frequently participate in heartbreaking and anxiety provoking events described as critical incidents. In this philosophical hermeneutic inquiry, four ER nurses were interviewed to uncover a deeper understanding of critical incidents, the meaning ascribed to critical incidents, and the needs of the nurses following the incident. Through this inquiry it was discovered that a sensation of falling may be felt by the nurse during participation in these events. This experience can be overwhelming and difficult to elucidate thus, ER nurses frequently utilize metaphors to assist in describing the distressing nature of critical incidents. Each nurse involved in an incident copes differently and in a manner best suited for him/her. Critical incident are an inevitable part of the life of an ER nurse and there may not be one single solution to assist all nurses with the process of managing painful personal thoughts, feelings, and emotions associated with critical incidents.

description: A rapid, reliable, sensitive, and multiplex colloidal gold immunochromatographic assay (CGIA) was developed for the simultaneous detection of three polyether ionophore antibiotics (PEs) in chicken muscle. The IC50 values of the optimized CGIA were 1.63, 1.94, and 1.18 ng/mL with a linear range of 0.87–3.04 ng/mL, 0.85–4.41 ng/mL, and 0.57–2.44 ng/mL for maduramicin (MAD), monensin (MON), and salinomycin (SAL), respectively. The cut-off values were 10, 5, and 5 ng/mL, respectively. The whole testing process was completed within 15 min. A parallel analysis in blind chicken muscle samples was conducted by liquid chromatography–tandem mass spectrometry (LC-MS/MS), the developed CGIA did not appear false-positive and false-negative. The results show that the established method could provide a rapid and effective approach for on-site screening and determination of PEs residues in chicken muscle samples.

description: Physicians play an important role in adapting to and mitigating the adverse health effects of the unfolding climate and ecological crises. To fully harness this potential, future physicians need to acquire knowledge, values, skills, and leadership attributes to care for patients presenting with environmental change-related conditions and to initiate and propel transformative change in healthcare and other sectors of society including, but not limited to, the decarbonization of healthcare systems, the transition to renewable energies and the transformation of transport and food systems. Despite the potential of Planetary Health Education (PHE) to support medical students in becoming agents of change, best-practice examples of mainstreaming PHE in medical curricula remain scarce both in Germany and internationally. The process of revising and updating the Medical Licensing Regulations and the National Competency-based Catalog of Learning Objectives for Medical Education in Germany provided a window of opportunity to address this implementation challenge. In this article, we describe the development and content of national Planetary Health learning objectives for Germany. We anticipate that the learning objectives will stimulate the development and implementation of innovative Planetary Health teaching, learning and exam formats in medical schools and inform similar initiatives in other health professions. The availability of Planetary Health learning objectives in other countries will provide opportunities for cross-country and interdisciplinary exchange of experiences and validation of content, thus supporting the consolidation of Planetary Health learning objectives and the improvement of PHE for all health professionals globally.

description: Objectives: Chimpanzees (Pan troglodytes) possess a relatively generalized molar morphology allowing them to access a wide range of foods. Comparisons of crown and cusp morphology among the four subspecies have suggested relatively large intraspecific variability. Here, we compare molar crown traits and cusp wear of two geographically close populations of Western chimpanzees, P. t. verus, to provide further information on intraspecific dental variability. Materials and Methods: Micro-CT reconstructions of high-resolution replicas of first and second molars of two Western chimpanzee populations from Ivory Coast (Taï National Park) and Liberia, respectively were used for this study. First, we analyzed projected tooth and cusp 2D areas as well as the occurrence of cusp six (C6) on lower molars. Second, we quantified the molar cusp wear three-dimensionally to infer how the individual cusps alter with advancing wear. Results: Both populations are similar in their molar crown morphology, except for a higher appearance rate of a C6 in Taï chimpanzees. In Taï chimpanzees, lingual cusps of upper molars and buccal cusps of lower molars possess an advanced wear pattern compared to the remaining cusps, while in Liberian chimpanzees this wear gradient is less pronounced. Discussion: The similar crown morphology between both populations fits with previous descriptions for Western chimpanzees and provides additional data on dental variation within this subspecies. The wear pattern of the Taï chimpanzees are in concordance with their observed tool rather than tooth use to open nuts/seeds, while the Liberian chimpanzees may have consumed hard food items crushed between their molars.

description: We report on longitudinal and transverse magnetisation measurements performed on single crystal samples of Gd2Ti2O7 for a magnetic field applied along the [100] direction. The measurements reveal the presence of previously unreported phases in fields below 10 kOe in an addition to the higher-field-induced phases that are also seen for H//[111], [110], and [112]. The proposed H-T phase diagram for the [100] direction looks distinctly different from all the other directions studied previously.

description: Aim: This systematic review aims to estimate the relationship between prenatal exposure to opioids and neurodevelopmental outcomes and examines potential sources of heterogeneity between the studies. Methods: We searched four databases through May 21st, 2022: PubMed, Embase, PsycInfo and the Web of Science according to a specified search strings. Study inclusion criteria include: (1) cohort and case-control peer-reviewed studies published in English; (2) studies comparing neurodevelopmental outcomes among children with prenatal opioid-exposure (prescribed or used non-medically) vs. an unexposed group. Studies investigating fetal alcohol syndrome or a different primary prenatal exposure other than opioids were excluded. Two main performed data extraction using “Covidence” systematic review platform. This systematic review was conducted in accordance with PRISMA guidelines. The Newcastle-Ottawa-Scale was used for quality assessment of the studies. Studies were synthesized based on the type of neurodevelopmental outcome and the instrument used to assess neurodevelopment. Results: Data were extracted from 79 studies. We found significant heterogeneity between studies due to their use of different instruments to explore cognitive skills, motor, and behavioral outcomes among children of different ages. The other sources of heterogeneity included: procedures to assess prenatal exposure to opioids; period of pregnancy in which exposure was assessed; type of opioids assessed (non-medical, medication used for opioid use dis-order, prescribed by health professional), types of co-exposure; source of selection of prenatally exposed study participants and comparison groups; and methods to address lack of comparability between exposed and unexposed groups. Cognitive and motor skills as well as behavior were generally negatively affected by prenatal opioid exposure, but the significant heterogeneity precluded a meta-analysis. Conclusion: We explored sources of heterogeneity in the studies assessing the association between prenatal exposure to opioids and neurodevelopmental outcomes. Sources of heterogeneity included different approaches to participant recruitment as well as exposure and outcome ascertainment methods. Nonetheless, overall negative trends were observed between prenatal opioid exposure and neuro-developmental outcomes.

description: We report electron impact ionization cross section measurements for electron impact single ionization of Fe12 + forming Fe13 + and electron impact double ionization of Fe12 + forming Fe14 +. These are the first electron impact ionization data for any Si-like ion uncontaminated by an unknown metastable fraction. Recent distorted wave calculations agree with our single ionization results to within ~15%. Double ionization is dominated by inner shell ionization of a 2l electron resulting in autoionization of a second electron as the inner shell hole is filled.

description: The reliability of digital devices is threatened by various sources, ranging from architectural issues and process variations to environmental fluctuations and noises. Also, error generated by these sources are inherently stochastic and transient. This makes reliability analysis an indispensable step of circuit design. Several reliability evaluation methods have been proposed for binary logic circuit. However, correlation of reliability with the input and gate errors and reliability analysis of multivalued circuits have not been investigated as of yet. This research investigates the reliability of switching circuits based on probabilistic models, and examines their applicability to multivalued circuits. We also develop an algebraic method for evaluating reliability of multivalued circuits. We further discuss how reliability of k-ary logic networks depends on radix k, input and gate errors. Thereafter, we propose a probabilistic model for representing and detecting faults. This research also studies behavior of probabilistic logic networks for very large (continuous) radix.
