description: We report high field magneto transport of Sm/PrFeAsO. Below spin density wave transition (TSDW), the magneto-resistance (MR) of Sm/PrFeAsO is positive and increasing with decreasing temperature. The MR of SmFeAsO, is found 16%, whereas the same is 21.5% in case of PrFeAsO, at 2.5 K under applied magnetic field of 14 Tesla (T). In case of SmFeAsO, the variation of isothermal MR with field below 20 K is nonlinear at lower magnetic fields (< 2 Tesla) and the same is linear at moderately higher magnetic fields (H \geq 3.5 T). On the other hand PrFeAsO shows almost linear MR at all temperatures below 20 K. The anomalous behavior of MR being exhibited in PrFeAsO is originated from Dirac cone states. The stronger interplay of Fe and Pr ordered moments is responsible for this distinct behavior. PrFeAsO also shows a hump in resistivity (R-T) with possible conduction band (FeAs) mediated ordering of Pr moments at around 12 K. However the same is absent in SmFeAsO even down to 2 K. Our results of high field magneto-transport of up to 14 Tesla brings about clear distinction between ground states of SmFeAsO and PrFeAsO.

description: Prediction of the Sun's magnetic activity is important because of its effect on space environment and climate. However, recent efforts to predict the amplitude of the solar cycle have resulted in diverging forecasts with no consensus. Yeates et al. (2008) have shown that the dynamical memory of the solar dynamo mechanism governs predictability and this memory is different for advection- and diffusion-dominated solar convection zones. By utilizing stochastically forced, kinematic dynamo simulations, we demonstrate that the inclusion of downward turbulent pumping of magnetic flux reduces the memory of both advection- and diffusion-dominated solar dynamos to only one cycle; stronger pumping degrades this memory further. Thus, our results reconcile the diverging dynamo-model-based forecasts for the amplitude of solar cycle 24. We conclude that reliable predictions for the maximum of solar activity can be made only at the preceding minimum--allowing about 5 years of advance planning for space weather. For more accurate predictions, sequential data assimilation would be necessary in forecasting models to account for the Sun's short memory.

description: This qualitative research project examines how monstrosity is articulated in the contemporary British horror fiction podcast The Magnus Archives (2016-2021), particularly through the main character, Jonathan “Jon” Sims. The podcast is set in a private research organization, the Magnus Institute, which collects first-hand accounts of supernatural experiences. Through a close thematic textual analysis, I argue that The Magnus Archives articulates monstrosity as deliberately cultivated in individuals by institutions through practices of surveillance, discipline, enculturation, and control. Through his work as the new head archivist of the titular archives, Jon is subjected to institutional surveillance that shapes his behaviour and his body. He becomes dependent on “consuming” statements, gradually taking more extreme actions to obtain them. Initially, it seems as though the podcast is trying to “democratize” monstrosity by portraying it as the result of institutional forces, while decoupling it from traditional markers of monstrosity such as queerness, ability/disability, or normative attractiveness. However, this articulation of monstrosity is shaped by the “invisibility” of the protagonist’s body, thanks to podcast form and conventions: he is presented by the text as “a-racial,” which usually results in characters being read as white. Jon’s maleness and (implied) whiteness are part of his becoming monstrous. Through Jon’s gradual journey into monsterhood, the podcast “monsterizes” and problematizes knowledge production within the Western context: archives and other institutions of knowledge production are inextricably linked to power, surveillance, and domination, particularly imperial domination, and cannot separate themselves from these origins, despite recent calls to “decolonize.” Within the monstrous institution, monstrous behaviour is rewarded, while attempts to subvert or disrupt the functioning of the Institute are punished. Jon is not monstrous because he disrupts normalcy, but because he adheres to it and is transformed by it. However, humanity and monstrosity are a continuum within the podcast, rather than two discrete categories, and Jon’s monstrous transformation exists in tension with his becoming kinder to the people around him, even as he extracts and consumes people’s trauma. It is because monstrosity is a spectrum that there are possibilities for resistance, even as one’s choices are limited or guided by institutional surveillance.

description: Peripheral nerve lesions provoke apoptosis in the dorsal horn of the spinal cord. The cause of cell death, the involvement of neurons, and the relevance for the processing of somatosensory information are controversial. Here, we demonstrate in a mouse model of sciatic nerve injury that glutamate-induced neurodegeneration and loss of γ-aminobutyric acid (GABA)ergic interneurons in the superficial dorsal horn promote the transition from acute to chronic neuropathic pain. Conditional deletion of Grin1, the essential subunit of N-methyl-d-aspartate-type glutamate receptors (NMDARs), protects dorsal horn neurons from excitotoxicity and preserves GABAergic inhibition. Mice deficient in functional NMDARs exhibit normal nociceptive responses and acute pain after nerve injury, but this initial increase in pain sensitivity is reversible. Eliminating NMDARs fully prevents persistent pain-like behavior. Reduced pain in mice lacking proapoptotic Bax confirmed the significance of neurodegeneration. We conclude that NMDAR-mediated neuron death contributes to the development of chronic neuropathic pain.

description: We investigate dissipation-induced p-wave paired states of fermions in two dimensions and show the existence of spatially separated Majorana zero modes in a phase with vanishing Chern number. We construct an explicit and natural model of a dissipative vortex that traps a single of these modes, and establish its topological origin by mapping the problem to a chiral one-dimensional wire where we observe a non-equilibrium topological phase transition characterized by an abrupt change of a topological invariant (winding number). We show that the existence of a single Majorana zero mode in the vortex core is intimately tied to the dissipative nature of our model. Engineered dissipation opens up possibilities for experimentally realizing such states with no Hamiltonian counterpart.

description: In this paper we review the theory of unconventional quantum critical points that are beyond the Landau's paradigm. Three types of unconventional quantum critical points will be discussed: (1). The transition between topological order and semiclassical spin ordered phase; (2). The transition between topological order and valence bond solid phase; (3). The direct second order transition between different competing orders. We focus on the field theory and universality class of these unconventional quantum critical points. Relation of these quantum critical points with recent numerical simulations and experiments on quantum frustrated magnets are also discussed.

description: The transition to adulthood has become prolonged in recent decades because of sociocultural and historical changes, such as the impact of the shift towards a knowledge economy on the school-to-work transition. It is now taking longer for young adults to achieve the traditional milestones of adulthood, such as marriage and parenthood. Research on the transition to adulthood has largely focused on the experiences of White middle-class populations with less focus on under-represented groups, such as youth in child welfare. The extended transition to adulthood is particularly concerning for this population because they are obligated to transition at age 18 and research has demonstrated that they tend to experience more negative outcomes, such as homelessness, poverty, incarceration, dependence on social services, early parenthood, and mental health and substance use issues. The present study investigated the transition experiences of youth in care to gain a better understanding of how to improve their experiences from their perspectives. A multiple case study design was used in which data was collected through semi-structured interviews. Participants included six youth aged 18 to 22 years and three service workers aged 28 to 46 years that were bounded into seven cases. A thematic analysis was completed in three stages to interpret the data. The analysis identified three overarching themes and 10 sub-themes. The themes revealed several key findings regarding their transition experiences: youth are not receiving enough direct support, they feel like the transition is sudden, they feel moderately prepared, they do participate in planning and decision making, and transition services are important for developing life skills. Based on these results, this study provided five recommendations to improve the transition experiences of youth in care.

description: The aim of this deliverable is to demonstrate the final version of the Virtual Coach (VC) component including all clinical and non-clinical coaching interventions that are used at both sites – ICSM and NKI – participating in clinical tests of the CAPABLE system. We would like to note that VC provides coaching related to adverse events associated with therapies of various cancer types, thus it goes beyond the two initially assumed use cases of renal cell carcinoma (RCC) and melanoma.
The detailed presentation of VC at the release candidate (RC) stage, including the actor-model-based architecture and the two-level hierarchy of computer-interpretable guidelines (CIGs), was provided in deliverable D5.5, therefore for the sake of brevity in this document, we focus on new elements introduced in the last phase of the development and refer the reader to relevant parts in D5.5 if necessary. Specifically, these new elements include motivational and administrative workflows and rules (e.g., motivational messages for My Usual Walk capsule, rewards for performing capsules, psychological and nutritional support), as well as architectural components and external tools for improving the reliability of VC.
This demonstration comprises a textual description and a video. The text in this document summarizes the final state of VC and provides details on the new developments mentioned above. Selected – most relevant and interesting – new elements are then presented in detail and demonstrated in the video available on the CAPABLE project website.
The structure of this document is as follows. In Section 3 we define the scope of demonstration. In Section 4 we provide an overview of the final version of VC considering its architecture, available CIGs and possible intervention and data enquiry types. In Section 5 we present the external monitoring and notification system that oversees VC in addition to its internal architectural components. Finally, we conclude with the summary in Section 6.

description: Stress granules are non-membranous structures that transiently form in the cytoplasm during cellular stress, where they promote translational repression of non-essential RNAs and modulate cell signaling by sequestering key signal transduction proteins. These and other functions of stress granules facilitate an adaptive cellular response to environmental adversity. A key component of stress granules is the prion-related RNA-binding protein, T cell intracellular antigen-1 (TIA-1). Here, we report that recombinant TIA-1 undergoes rapid multimerization and phase separation in the presence of divalent zinc, which can be reversed by the zinc chelator, TPEN. Similarly, the formation and maintenance of TIA-1-positive stress granules in arsenite-treated cells are inhibited by TPEN. In addition, Zn2+ is released in cells treated with arsenite, before stress granule formation. These findings suggest that Zn2+ is a physiological ligand of TIA-1, acting as a stress-inducible second messenger to promote multimerization of TIA-1 and subsequent localization into stress granules.

description: ECSIT is a mitochondrial complex I (CI)-associated protein that has been shown to regulate the production of mitochondrial reactive oxygen species (mROS) following engagement of Toll-like receptors (TLRs). We have generated an Ecsit conditional knockout (CKO) mouse strain to study the in vivo role of ECSIT. ECSIT deletion results in profound alteration of macrophage metabolism, leading to a striking shift to reliance on glycolysis, complete disruption of CI activity, and loss of the CI holoenzyme and multiple subassemblies. An increase in constitutive mROS production in ECSIT-deleted macrophages prevents further TLR-induced mROS production. Surprisingly, ECSIT-deleted cells accumulate damaged mitochondria because of defective mitophagy. ECSIT associates with the mitophagy regulator PINK1 and exhibits Parkin-dependent ubiquitination. However, upon ECSIT deletion, we observed increased mitochondrial Parkin without the expected increase in mitophagy. Taken together, these results demonstrate a key role of ECSIT in CI function, mROS production, and mitophagy-dependent mitochondrial quality control.

description: In this paper we consider theories in which reality is described by some underlying variables. Each value these variables can take represents an ontic state (a particular state of reality). The preparation of a quantum state corresponds to a distribution over the ontic states. If we make three basic assumptions, we can show that the distributions over ontic states corresponding to distinct pure states are non-overlapping. This means that we can deduce the quantum state from a knowledge of the ontic state. Hence, if these assumptions are correct, we can claim that the quantum state is a real thing (it is written into the underlying variables that describe reality). The key assumption we use in this proof is ontic indifference - that quantum transformations that do not affect a given pure quantum state can be implemented in such a way that they do not affect the ontic states in the support of that state. In fact this assumption is violated in the Spekkens toy model (which captures many aspects of quantum theory and in which different pure states of the model have overlapping distributions over ontic states). This paper proves that ontic indifference must be violated in any model reproducing quantum theory in which the quantum state is not a real thing. The argument presented in this paper is different from that given in a recent paper by Pusey, Barrett, and Rudolph. It uses a different key assumption and it pertains to a single copy of the system in question.

Reforestation under climate change in British Columbia : an institutional assessment
Creators: name: Pérez, David Manuel
Publisher: name: University of British Columbia
Year: 2012

description: Reforestation is the most important part of any strategy intended to establish desired future forest conditions, including climate change resilience. Forest managers have a wide range of choices around forest regeneration. They can select among different tree species, genotypes, planting mixes; and silvicultural systems. Over time these choices influence forest composition, structure, and function that then affect the provision of forest values. In British Columbia (BC), climate change has been raised as major issue in terms of its current and projected impacts on forests resources, yet managing to address them remains uncommon. This raises questions about the institutional framework governing management and its influence on the capacity to use reforestation to adapt to climate change. This study describes how climate is changing in BC, adaptations in the forest sector, and the adaptation research efforts to date. It describes the policy environment and associated regulations that direct and guide management on public land in BC and their influence on the ability to use reforestation for climate change adaptation. This includes requirements for reestablishing free growing timber stands, the treatment of silvicultural costs under the stumpage system, and the use of alternative forest stocking standards not found in government guidebooks. Barriers to adaptive management are identified through two surveys of respondents directly involved in reforestation planning and implementation in BC. Important institutional barriers and risks to adaptation are identified as well as incentives and policy alternatives to facilitate it. Perspectives of government managers, licensees, researchers, and practitioners show a common belief that the climate is changing and that the responsibility to future generations for climate vulnerability reduction and forest resilience lies in the present. Nevertheless, differences in perspectives emerge at more operational levels and several factors may constrain the flexibility necessary for the use of adaptive reforestation strategies, especially, aversion to risk, timber supply impacts, stocking standard approval, free growing determination criteria, and silvicultural investment security. While sustainable forest management is the ideal framework for adaptation, it will not occur without policy adjustments to address these barriers and to provide an environment in which forest resilience is a key management objective.

The Ward identities for the generating functionals of Green's functions are derived, and their gauge dependence is investigated. We discuss the Gribov-Zwanziger action for the one-parameter family of R_xi gauges. It is argued that gauge theories with a soft breaking of BRST symmetry are inconsistent.

description: Hill agriculture, characterized by undulating terrains and intricate poly-culture and agroforestry systems, serves as a vital livelihood source for human inhabitants. Employing traditional cultivation methods on ridges and valleys, small-scale farmers achieve remarkable productivity and stability, yielding high returns per unit of labor and energy. This agricultural approach mirrors natural ecosystems, boasting a rich organic environment, disease-resistant biodiversity, and inherent stability. Despite relying predominantly on rainfed methods, the sustainability of hill agriculture has endured through centuries of practice.

This paper delves into the unique characteristics and sustainability of hill agriculture, drawing parallels between its practices and natural ecosystem dynamics. Through an exploration of traditional cultivation techniques and their alignment with ecological principles, it elucidates the resilience and productivity inherent in this agricultural approach. Emphasizing the significance of small-scale farming communities, the paper underscores their role as stewards of biodiversity and guardians of traditional knowledge systems.

Moreover, the paper addresses the challenges and opportunities facing hill agriculture in the contemporary context. In light of increasing environmental pressures and changing socio-economic dynamics, it advocates for the preservation and promotion of traditional agricultural practices. By harnessing indigenous knowledge and integrating modern innovations judiciously, stakeholders can enhance the resilience and sustainability of hill agriculture while safeguarding the livelihoods of communities reliant on these practices.

This study contributes to a deeper understanding of the intricate relationships between human societies, natural ecosystems, and agricultural practices in hill regions. It highlights the importance of adopting holistic approaches that prioritize ecological integrity, socio-economic equity, and cultural preservation. Through informed policy interventions and community-led initiatives, hill agriculture can continue to thrive as a resilient and sustainable livelihood strategy, nourishing both people and the planet.

description: The phosphoinositide phosphatase synaptojanin 1 (SYNJ1) is a key regulator of synaptic function. We first tested whether SYNJ1 contributes to phenotypic variations in familial Alzheimer’s disease (FAD) and show that SYNJ1 polymorphisms are associated with age of onset in both early- and late-onset human FAD cohorts. We then interrogated whether SYNJ1 levels could directly affect memory. We show that increased SYNJ1 levels in autopsy brains from adults with Down syndrome (DS/AD) are inversely correlated with synaptophysin levels, a direct readout of synaptic integrity. We further report age-dependent cognitive decline in a mouse model overexpressing murine Synj1 to the levels observed in human sporadic AD, triggered through hippocampal hyperexcitability and defects in the spatial reproducibility of place fields. Taken together, our findings suggest that SYNJ1 contributes to memory deficits in the aging hippocampus in all forms of AD.

description: We study the Casimir interaction in the plane-sphere geometry in the classical limit of high temperatures. In this limit, the finite conductivity of the metallic plates needs to be taken into account. For the Drude model, the classical Casimir interaction is nevertheless found to be independent of the conductivity so that it can be described by a single universal function depending only on the aspect ratio $x=L/R$ where $L$ is the interplate distance and $R$ the sphere radius. This universal function differs from the one found for perfect reflectors and is in principle amenable to experimental tests. The asymptotic approach of the exact result to the Proximity Force Approximation appears to be well fitted by polynomial expansions in $\ln x$.

description: This document explores the use of storytelling animation as a medium to uncover and amplify the marginalized narratives of women involved in the Canadian energy sector during the mid-20th century. This paper’ focus is on the significant yet often overlooked contributions of "oil wives" during the Alberta oil boom, specifically following the Leduc No.1 oil discovery in the 1940s. Through a combination of women’s narratives and storytelling animation, this research re-examines historical accounts to reveal the diverse experiences and roles of women in energy development. My methodological approach in this project involved extensive archival research, thematic analysis, and the production of animated documentaries. Archival materials from the Canadian Energy Museum and documented interviews with surviving oil women and their descendants were utilized to construct compelling narratives. These narratives were then brought to life through storytelling animations, employing techniques such as rotoscoping and digital collage to maintain historical accuracy and emotional depth. The findings highlighted in my thesis project emphasize the critical roles played by women in supporting the oil industry and their families, challenging the male-dominated narratives that have traditionally shaped our understanding of energy history. By positioning animation as a form of meta-interpretation, this project demonstrates its capacity to convey historical and emotional truths that might not be captured through conventional documentary methods. Storytelling animation, unlike static media like photographs, possesses the unique ability to breathe life into undocumented or abstract narratives, enabling the portrayal of emotions, memories, and historical events that may not have a tangible visual record. This paper contributes to the broader discourse on energy, gender, and historical representation, advocating for more inclusive and equitable narratives in both academic research and public history. It also underscores the potential for innovative storytelling techniques, such as documentary animation, to enrich our collective memory and advance social justice.

description: First responders (FRs) are at increased risk for experiencing compromised physical (Suyama et al., 2009), psychological (Carleton et al., 2018a), and emotional well-being (Wilson et al., 2016). While there are various supports available for FRs, research demonstrates that FRs tend to rely on their spouses/partners for support (Carleton et al., 2019a). Spouses/partners have been found to be affected by the stress of their FR partner (Casas & Benuto, 2022); however, there is a lack of validated psychosocial programs available for FR spouses within Canada (Baek, 2020). Given that resources and services for FR spouses/partners are scarce, an objective of this research is to explore the effectiveness of the Re:Building Families (RBF) program. The RBF program seeks to fill a gap in the literature by providing psychoeducation and peer-support to spouses/partners of FRs. The current study analyzed data from 73 FR spouses/partners who participated in the RBF program. Data was collected at pre-program, post-program, and three-month follow-up. Results indicated that FR spouses/partners tend to report moderately high levels of stress, resilience, and general family functioning. ANOVAs revealed that resilience did not differ across time, by service area, or by length of service. However, resilience was found to significantly decrease across time for FR spouses/partners who do not have children when compared to those who do have children. LGM analyses revealed that resilience was not found to change significantly over time; however, general functioning and stress were found to worsen over time. Parallel process analyses indicated that changes in resilience are not associated with changes in general family functioning or stress over time. Results are discussed in terms of bioecological systems theory, family systems theory, and based on the available literature on FR spouses and families. The current study addresses a gap in the literature by providing preliminary findings on the effectiveness of a psychoeducational program for FR spouses and by further exploring resilience, stress, and family functioning in FR spouses. Implications for the development and refinement of future programs are discussed.

description: A hallmark of recent higher education policy in developed economies is the move towards quasi-markets involving greater student choice and provider competition, underpinned by cost-sharing policies. This paper examines the idealizations and illusions of student choice and marketization in higher education policy in England, although the overall conclusions have relevance for other countries whose higher education systems are shaped by neoliberal thinking. First, it charts the evolution of the student-choice rationale through an analysis of government commissioned reports, white papers, and legislation, focusing on policy rhetoric and the purported benefits of increasing student choice and provider competition. Second, the paper tests the predictions advanced by the student-choice rationale—increased and wider access, improved institutional quality, and greater provider responsiveness to the labour market—and finds them largely not met. Finally, the paper explores how conceptual deficiencies in the student-choice model explain why the idealization of student choice has largely proved illusionary. Government officials have narrowly conceptualized students as rational calculators primarily weighing the economic costs and benefits of higher education and the relative quality of institutions and programs. There is little awareness that student choices are shaped by several other factors as well and that these vary considerably by social background. The paper concludes that students’ choices are socially constrained and stratified, reproducing and legitimating social inequality.

description: Equity gaps exist in degree completions in U.S. higher education and the high cost of higher education is a major contributor to these inequitable outcomes. Specifically, textbook costs are rising faster than college tuition, which is disproportionately affecting certain populations. A viable alternative to traditional textbooks is the use of Open Educational Resources (OER). OER have been proven to result in equal or higher student outcomes when used as textbook replacement, yet their diffusion as an educational innovation has not been largely successful. Using Roger’s Diffusion Theory, this study’s purpose was to address the differential access to learning materials by examining student and faculty ratings of OER gains, along with the student demographic and enrollment characteristics that have a relationship with student ratings of OER gains. This quantitative study utilized the secondary analysis of an OER Hub dataset from 2015 to gain insight into the ratings of OER gains by early adopters of OER, who are opinion leaders according to Diffusion Theory. Causal Comparative design was used to compare the OER gains ratings from different groups: students and instructors, and students by the following group characteristics: full-time/part-time, online/in-person, employment, ESL, age, ability, and gender. Overall, instructors rated student OER gains significantly lower than students did, reflecting a clear misalignment and misunderstanding of student OER gains by instructors. Additionally, the following student characteristics did not diminish student OER gains: full-time/part-time enrollment status, online/in-person modality, ESL, Employment status, ability, and gender. This study found that OER equitably serves traditionally underserved groups in U.S. higher education.

description: In recent years, microservices have become a dominant architecture in software development, offering scalability, modularity, and agility to development processes. However, ensuring optimal performance before deployment poses a significant challenge, particularly in the fast-paced environments of Continuous Integration/Continuous Deployment (CI/CD) pipelines. Traditional performance testing methods, which rely on synthetic scenarios and lengthy testing processes, can be difficult to adopt in environments where testing needs to be both realistic and quick. To address the need for accurate and responsive testing, my work proposes and implements an innovative framework that uses real-world usage traces to identify and execute a small yet essential set of performance tests. This approach aims to seamlessly integrate with CI/CD workflows, providing developers with quick feedback on performance issues and scalability constraints that may arise from changes to one or more microservices. Through a series of empirical evaluations, I compare the effectiveness of six techniques using 12 real-world traces chosen based on their timeseries characteristics. My work aims to identify a set of performance tests that can capture historically observed system behaviour and be executed within a specified time budget. In this work, I present and test 6 different techniques for load test generation. Of the 6 techniques tested, Interval Sampling (IS) was the most reliably accurate for all traces tested. Using this technique, I was able to replicate the response time distribution of a 24-hour test on our custom testbench within just a five-minute test, achieving a mean relative percent error of only 1.12% and 2.73% at the 90th and 95th percentiles. This considerable decrease in time and resources necessary for load testing and response time modelling demonstrates the efficiency and effectiveness of my approach.

description: Extreme events occur in science, engineering, finance and many related fields. The generalized extreme value (GEV) distribution is often used to model extreme events. In this thesis, we study the estimation of GEV related parameters and events using three different approaches. The maximum likelihood approach is a frequentist approach, which has a fully developed theory for both estimation and inference subject to the existence of maximum likelihood estimators and expected and/or observed information matrix. The Bayesian approach starts with the likelihood function, chooses appropriate prior distributions for the GEV distribution parameters, and works with the posterior distribution of the parameters for estimation and inference. The resampling approach may or may not use the likelihood function to estimate the GEV parameters, and inference is based on the variations generated from resampling the observed data directly or indirectly and repeating the estimation procedure. All three approaches are well known in the literature, the main contribution of this thesis is, to the best of our knowledge, that the three approaches are studied and compared under the same setup for the first time, and based on extensive comparisons and the criteria used we are able to recommend the parametric resampling approach based on the empirical distribution function (EDF) estimation, with percentile confidence intervals to practitioners to use. The use of the maximum likelihood, Bayesian, and resampling approaches is illustrated through a case study.

description: We present results on the magnetoresistance of the system Ni/Al203/n-doped Si/Al2O3/Ni in fabricated nanostructures. The results at temperature of 14K reveal a 75% magnetoresistance that decreases in value up to approximately 30K where the effect disappears. We observe minimum resistance in the antiparallel configurations of the source and drain of Ni. As a possibility, it seems to indicate the existence of a magnetic state at the Si/oxide interface. The average spin diffusion length obtained is of 650 nm approximately. Results are compared to the window of resistances that seems to exist between the tunnel barrier resistance and two threshold resistances but the spin transfer seems to work in the range and outside the two thresholds.

 Remarks. Paracyclois was placed in the Official List of Generic Names (Opinion 73) as “ Paracyclois Miers, 1886, Rep. Voy. ‘Challenger’ (Zool.) 17 (No 2): 288 (gender: feminine) (type species, by monotypy: Paracyclois milneedwardsii Miers, 1886, Rep. Voy. ‘Challenger’ (Zool.) 17 (No 2): 289) (Crustacea, Decapoda)”. This is incorrect and should be cited as Paracyclois Miers, 1885. But following Articles 79.4 and 80.9 (ICZN 1999), the year 1886 will remain in use until the Commission makes a subsequent correction (Article 80.4).
