description: Graphene has extraordinary electronic and optical properties and holds great promise for applications in photonics and optoelectronics. Demonstrations including high-speed photodetectors, optical modulators, plasmonic devices, and ultrafast lasers have now been reported. More advanced device concepts would involve photonic elements such as cavities to control light-matter interaction in graphene. Here we report the first monolithic integration of a graphene transistor and a planar, optical microcavity. We find that the microcavity-induced optical confinement controls the efficiency and spectral selection of photocurrent generation in the integrated graphene device. A twenty-fold enhancement of photocurrent is demonstrated. The optical cavity also determines the spectral properties of the electrically excited thermal radiation of graphene. Most interestingly, we find that the cavity confinement modifies the electrical transport characteristics of the integrated graphene transistor. Our experimental approach opens up a route towards cavity-quantum electrodynamics on the nanometre scale with graphene as a current-carrying intra-cavity medium of atomic thickness.

description: The conjugacy of split Cartan subalgebras in the finite dimensional simple case (Chevalley) and in the symmetrizable Kac-Moody case (Peterson-Kac) are fundamental results of the theory of Lie algebras. Among the Kac-Moody Lie algebras the affine algebras stand out. This paper deals with the problem of conjugacy for a class of algebras --extended affine Lie algebras-- that are in a precise sense higher nullity analogues of the affine algebras. Unlike the methods used by Peterson-Kac, our approach is entirely cohomological and geometric. It is deeply rooted on the theory of reductive group schemes developed by Demazure and Grothendieck, and on the work of J. Tits on buildings

description: We report resistivity $ρ$ and thermal conductivity $κ$ measurements on Ca$_3$Ir$_4$Sn$_{13}$ single crystals, in which superconductivity with $T_c \approx 7$ K was claimed to coexist with ferromagnetic spin-fluctuations. Among three crystals, only one crystal shows a small hump in resistivity near 20 K, which was previously attributed to the ferromagnetic spin-fluctuations. Other two crystals show the $ρ\sim T^2$ Fermi-liquid behavior at low temperature. For both single crystals with and without the resistivity anomaly, the residual linear term $κ_0/T$ is negligible in zero magnetic field. In low fields, $κ_0(H)/T$ shows a slow field dependence. These results demonstrate that the superconducting gap of Ca$_3$Ir$_4$Sn$_{13}$ is nodeless, thus rule out nodal gap caused by ferromagnetic spin-fluctuations.

description: Electric drives often do not have a smooth torque. In most cases they are coupled with mechanical systems. These tend to have natural frequencies. Therefore, it is advisable to eliminate harmonics from the torque pulsation if they are close to a natural frequency. One possibility to do this is harmonic current injection or HCI for short. However, the question arises, how exactly this harmonic current should be. The fact that a harmonic in the torque can be influenced by the d and q current results in a greater degree of freedom. This paper presents a method to investigate all possible solutions. Furthermore, two optimization possibilities for the current trajectory are presented. The effect of this selection on the maximum torque speed curve is shown. It has been found that the method which minimizes the induced voltage achieves an up to 8% larger range of application in this example.

description: Mit dem steigenden weltweiten Energiebedarf werden erneuerbare Energieträger wie Photovoltaik in Zukunft immer mehr an Bedeutung gewinnen. Die präzise Schätzung der Ausgangsleistung von Photovoltaikmodulen ist wesentlich für die korrekte Bemessung von Photovoltaikanlagen. Eine Herangehensweise um die Prä-Standardisierung von Dünnschicht-Photovoltaikmodulen zu verbessern, ist die Dunkelstrom-Stabilisierung (dark bias stabilization). Obwohl es die Grundidee schon seit Jahrzehnten gibt, ist in der näheren Vergangenheit wenig zu dem Thema geforscht worden. Im Zuge dieser Diplomarbeit habe ich zunächst eine Literaturrecherche zum Thema Dunkelstrom-Stabilisierung durchgeführt, gefolgt von Dunkelstrom-Stabilisierungs-Experimenten an verschiedenen Photovoltaikmodultypen. Nach dem Pearl-TF PV Report, der den Ausschlag für den Beginn dieser Arbeit gab, fand ich positive Ergebnisse für Dunkelstrom-Stabilisierung von CZTS Minimodulen unter der Verwendung von Vorströmen kleiner als die Kurzschlussströme der betrachteten Module. Für die großen CIGS und mono-c-Si Module waren die Ergebnisse weniger vielversprechend, vermutlich aufgrund schlecht gewählter Parameter für die Stabilisierung. Zusammenfassend wurde beobachtet, dass Dunkelstrom-Stabilisierung tatsächlich eine gültige, kostengünstigere Alternative zu den traditionellen Stabilisierungsmethoden bieten kann, und in Zukunft weiter an dem Thema geforscht werden sollte.
description: With the increasing world energy demand, renewable power sources like photovoltaics will become more and more important for our future. The accurate estimation of output power of photovoltaic modules is crucial for the correct sizing of photovoltaic power plants. One approach to improve pre-standardization methods in the field of thin film photovoltaic devices is dark bias stabilization. While the idea has been out for decades, there has been little research in the recent past. For this thesis, I made a literature research in dark bias stabilization, followed by dark biasing experiments on photovoltaic modules. In accordance with the Pearl-TF PV report that sparked this thesis, I found favorable results in dark biasing of CZTS minimodules with biasing currents smaller than the short circuit current of the biased module. For the full scale CIGS and mono-c-Si modules the results were less promising, most likely due to bad choice of bias parameters. It can be concluded that dark bias stabilization may in fact be a valid, more economic alternative to more traditional stabilization techniques and should be investigated further in the future.

description: One of the processes that may play a key role in plant species coexistence and ecosystem functioning is plant–soil feedback, the effect of plants on associated soil communities and the resulting feedback on plant performance. Plant–soil feedback at the interspecific level (comparing growth on own soil with growth on soil from different species) has been studied extensively, while plant–soil feedback at the intraspecific level (comparing growth on own soil with growth on soil from different accessions within a species) has only recently gained attention. Very few studies have investigated the direction and strength of feedback among different taxonomic levels, and initial results have been inconclusive, discussing phylogeny, and morphology as possible determinants. To test our hypotheses that the strength of negative feedback on plant performance increases with increasing taxonomic level and that this relationship is explained by morphological similarities, we conducted a greenhouse experiment using species assigned to three taxonomic levels (intraspecific, interspecific, and functional group level). We measured certain fitness‐related aboveground traits and used them along literature‐derived traits to determine the influence of morphological similarities on the strength and direction of the feedback. We found that the average strength of negative feedback increased from the intraspecific over the interspecific to the functional group level. However, individual accessions and species differed in the direction and strength of the feedback. None of our results could be explained by morphological dissimilarities or individual traits. Synthesis. Our results indicate that negative plant–soil feedback is stronger if the involved plants belong to more distantly related species. We conclude that the taxonomic level is an important factor in the maintenance of plant coexistence with plant–soil feedback as a potential stabilizing mechanism and should be addressed explicitly in coexistence research, while the traits considered here seem to play a minor role.

Law's permissions, law's exclusions : precarious migration status in Canada
Creators: name: Marsden, Sarah Grayce
Publisher: name: University of British Columbia
Year: 2013

description: The number of people with less than permanent migration status in Canada has increased in recent decades. While such people often have social and economic ties to Canada, and live and work within its territory, they do not have legal permanent membership by way of permanent residence or citizenship, and experience differential access to legal rights and entitlements. This dissertation examines the role of migration status in the lives of people who identify themselves as having “uncertain” migration status. In this study, I draw on interviews with migrants and representatives of migrant-serving agencies as well as legal and policy texts, deploying Dorothy Smith’s institutional ethnography as a methodology to ground the dissertation both analytically and structurally in the interview data. This study enlarges the understanding of the nature and effects of migration status as it is enacted in local institutional sites. Using the construct of “precarious migration status” as a theoretical frame, I focus specifically on the nature and effects of precarious migration status. I explore the effect of precarious migration status on working life and on migrants’ interactions with state institutions governing health care, education, and income security. I conclude that precarious migration status has a deleterious effect on the employment relationship itself as well as access to worker protections, even though the law creates no formal barrier to such protections on the basis of status. With regard to social state, individuals with precarious status are often formally excluded in the text of the law as well as through various exclusionary policies and practices within local institutional sites. I conclude that institutional sites in which precarious migration status functions to exclude should be understood as forms of enforcement. I further conclude that human rights and anti-discrimination strategies through Charter and provincial human rights statutes, while valuable, are unlikely to improve inclusion for precarious migrants, while contestation of membership at the level of local institutions has greater potential to do so.
On an Achievable Rate of Large Rayleigh Block-Fading MIMO Channels with No CSI

description: Training-based transmission over Rayleigh block-fading multiple-input multiple-output (MIMO) channels is investigated. As a training method a combination of a pilot-assisted scheme and a biased signaling scheme is considered. The achievable rates of successive decoding (SD) receivers based on the linear minimum mean-squared error (LMMSE) channel estimation are analyzed in the large-system limit, by using the replica method under the assumption of replica symmetry. It is shown that negligible pilot information is best in terms of the achievable rates of the SD receivers in the large-system limit. The obtained analytical formulas of the achievable rates can improve the existing lower bound on the capacity of the MIMO channel with no channel state information (CSI), derived by Hassibi and Hochwald, for all signal-to-noise ratios (SNRs). The comparison between the obtained bound and a high SNR approximation of the channel capacity, derived by Zheng and Tse, implies that the high SNR approximation is unreliable unless quite high SNR is considered. Energy efficiency in the low SNR regime is also investigated in terms of the power per information bit required for reliable communication. The required minimum power is shown to be achieved at a positive rate for the SD receiver with no CSI, whereas it is achieved in the zero-rate limit for the case of perfect CSI available at the receiver. Moreover, numerical simulations imply that the presented large-system analysis can provide a good approximation for not so large systems. The results in this paper imply that SD schemes can provide a significant performance gain in the low-to-moderate SNR regimes, compared to conventional receivers based on one-shot channel estimation.

description: In this study we compared the phylogeographic patterns of two Rusa species, Rusa unicolor and Rusa timorensis, in order to understand what drove and maintained differentiation between these two geographically and genetically close species and investigated the route of introduction of individuals to the islands outside of the Sunda Shelf. We analyzed full mitogenomes from 56 archival samples from the distribution areas of the two species and 18 microsatellite loci in a subset of 16 individuals to generate the phylogeographic patterns of both species. Bayesian inference with fossil calibration was used to estimate the age of each species and major divergence events. Our results indicated that the split between the two species took place during the Pleistocene, similar to 1.8Mya, possibly driven by adaptations of R. timorensis to the drier climate found on Java compared to the other islands of Sundaland. Although both markers identified two well-differentiated clades, there was a largely discrepant pattern between mitochondrial and nuclear markers. While nDNA separated the individuals into the two species, largely in agreement with their museum label, mtDNA revealed that all R. timorensis sampled to the east of the Sunda shelf carried haplotypes from R. unicolor and one Rusa unicolor from South Sumatra carried a R. timorensis haplotype. Our results show that hybridization occurred between these two sister species in Sundaland during the Late Pleistocene and resulted in human-mediated introduction of hybrid descendants in all islands outside Sundaland.

description: Properly designed (randomized and/or balanced) experiments are standard in ecological research. Molecular methods are increasingly used in ecology, but studies generally do not report the detailed design of sample processing in the laboratory. This may strongly influence the interpretability of results if the laboratory procedures do not account for the confounding effects of unexpected laboratory events. We demonstrate this with a simple experiment where unexpected differences in laboratory processing of samples would have biased results if randomization in DNA extraction and PCR steps do not provide safeguards. We emphasize the need for proper experimental design and reporting of the laboratory phase of molecular ecology research to ensure the reliability and interpretability of results.

No excess above the Standard Model background expectation is observed and a 95% CL visible cross section upper limit for new phenomena is set. A 95% CL lower limit of 32 TeV is set on the GMSB breaking scale Lambda independent of tan(beta). These limits provide the most stringent tests to date in a large part of the considered parameter space.

description: We present predictions for the gluon-fusion Higgs $p_T$ spectrum at N$^3$LL$'$+N$^3$LO order including fiducial cuts as required by experimental measurements at the Large Hadron Collider. Integrating the spectrum, we predict for the first time the total fiducial cross section to third order (N$^3$LO) and improved by resummation. The N$^3$LO correction is enhanced by cut-induced logarithmic effects and is not reproduced by the inclusive N$^3$LO correction times a lower-order acceptance. These are the highest-order predictions of their kind achieved so far at a hadron collider.

description: The proliferation of portable devices (PDAs, smartphones, digital multimedia players, and so forth) allows mobile users to carry around a pool of computing, storage and communication resources. Sharing these resources with other users ("Digital Organisms" -- DOs) opens the door to novel interesting scenarios, where people trade resources to allow the execution, anytime and anywhere, of applications that require a mix of capabilities. In this paper we present a fully distributed approach for resource sharing among multiple devices owned by different mobile users. Our scheme enables DOs to trade computing/networking facilities through an auction-based mechanism, without the need of a central control. We use a set of numerical experiments to compare our approach with an optimal (centralized) allocation strategy that, given the set of resource demands and offers, maximizes the number of matches. Results confirm the effectiveness of our approach since it produces a fair allocation of resources with low computational cost, providing DOs with the means to form an altruistic digital ecosystem.

description: Schwefel-basierte Elektroden haben wegen ihrer möglichen Anwendung in der nächsten Generation Akkumulatoren große Aufmerksamkeit auf sich gezogen; insbesondere da Schwefel ein umweltfreundliches und reichlich vorhandenes Element ist, das für die reversible elektrochemische Reaktion mit Lithium eine theoretische Kapazität von ungefähr 1675 mAh g-1 hat. Die Elektrochemie des Schwefels ist aber deutlich komplizierter als die der häufig angewandten Insertionsmaterialien in Lithium-Ionen-Akkumulatoren. Die elektrochemische Reduktion des in Lithium-Schwefel-Zellen enthaltenden Schwefels geschieht durch einen stufenweisen Mechanismus, bei dem lösliche Polysulfide gebildet werden. Das Auflösen von aktivem Material ist für die Zelle allerdings sehr schädlich, da dies mit einem Kapazitätsverlust der Elektrode einhergeht. Das bedeutet, dass dem Elektrolyten in diesem Akkumulator-Typ eine besonders wichtige Rolle zukommt – wichtiger noch als in anderen Systemen, in denen er nur ein Ionenleiter ist. In der nachfolgenden Arbeit werden die Zersetzungsreaktionen des am häufigsten verwendeten Elektrolyten für Lithium-Schwefel-Akkumulatoren studiert. Es ist bekannt, dass diese Reaktionen eine große Auswirkung auf die Elektrochemie des Schwefels haben. Der erste Teil dieser Arbeit besteht aus der Untersuchung von Zersetzungsreaktionen des Elektrolyten aufgrund gelösten Sauerstoffes. Dadurch wird ein tieferes Verständnis der Schwefel-Elektrochemie erhalten. In dem zweiten Teil dieser Arbeit wird der Effekt der höhen Spannung während der Lithiumsulfid-Aktvierung studiert, mit Fokus auf deren Auswirkung auf die Elektrolytzersetzung. Lithiumsulfid ist die vollständig lithiierte Form des Schwefels und entspricht somit dem entladenen Kathodenmaterial. Um diese Auswirkung zu analysieren, wurde ein neuartiges Lithiumsulfid-basiertes Material entwickelt, nämlich Lithiumsulfid mit eingebetteten Ethylendiamin-Molekülen. Dieses Material zeigt eine sehr niedrige Aktivierungsspannung, was dabei helfen kann, den Zersetzungsmechanismus des Elektrolytes wegen hoher Spannungen zu erklären.

description: We discuss a five-dimensional Minimal Supersymmetric Standard Model compactified on a $S^1/Z_2$ orbifold, looking at, in particular, the one-loop evolution equations of the Yukawa couplings for the quark sector and various flavor observables. Different possibilities for the matter fields are discussed, that is, where they are in the bulk or localised to the brane. The two possibilities give rise to quite different behaviours. By studying the implications of the evolution with the renormalisation group of the Yukawa couplings and of the flavor observables we find that, for a theory that is valid up to the unification scale, the case where fields are localised to the brane, with a large $\tanβ$, would be more easily distinguishable from other scenarios.

description: The Gini coefficient features prominently in Amartya Sen’s 1973 and 1997 seminal work on income inequality and social welfare. We construct the Gini coefficient from social-psychological building blocks, reformulating it as a ratio between a measure of social stress and aggregate income. We determine when as a consequence of an income gain by an individual, an increase in the social stress measure dominates a concurrent increase in the aggregate income, such that the magnitude of the Gini coefficient increases. By integrating our approach to the construction of the Gini coefficient with Sen’s social welfare function, we are able to endow the function with a social-psychological underpinning, showing that this function, too, is a composite of a measure of social stress and aggregate income. We reveal a dual role played by aggregate income as a booster of social welfare in Sen’s social welfare function. Quite surprisingly, we find that a marginal increase of income for any individual, regardless of the position of the individual in the hierarchy of incomes, improves welfare as measured by Sen’s social welfare function.

description: We study a Bayesian approach to recovering the initial condition for the heat equation from noisy observations of the solution at a later time. We consider a class of prior distributions indexed by a parameter quantifying "smoothness" and show that the corresponding posterior distributions contract around the true parameter at a rate that depends on the smoothness of the true initial condition and the smoothness and scale of the prior. Correct combinations of these characteristics lead to the optimal minimax rate. One type of priors leads to a rate-adaptive Bayesian procedure. The frequentist coverage of credible sets is shown to depend on the combination of the prior and true parameter as well, with smoother priors leading to zero coverage and rougher priors to (extremely) conservative results. In the latter case credible sets are much larger than frequentist confidence sets, in that the ratio of diameters diverges to infinity. The results are numerically illustrated by a simulated data example.

description: We present the results of three-dimensional simulations of quasar polarizations in the presence of pseudoscalar-photon mixing in the intergalactic medium. The intergalactic magnetic field is assumed to be uncorrelated in wave vector space but correlated in real space. Such a field may be obtained if its origin is primordial. Furthermore we assume that the quasars, located at cosmological distances, have negligible initial polarization. In the presence of pseudoscalar-photon mixing we show, through a direct comparison with observations, that this may explain the observed large scale alignments in quasar polarizations within the framework of big bang cosmology. We find that the simulation results give a reasonably good fit to the observed data.

description: A reliable and cost-effective interconnect technology is required for the development of hybrid pixel detectors. The interconnect technology needs to be adapted for the pitch and die sizes of the respective applications. For small-scale applications and during the ASIC and sensor development phase, interconnect technologies must also be suitable for the assembly of single-dies typically available from Multi-Project-Wafer submissions. Within the CERN EP R&D program and the AIDAinnova collaboration, innovative and scalable hybridization concepts are under development for pixel-detector applications in future colliders. This contribution presents recent results of a newly developed in-house single-die interconnection process based on Anisotropic Conductive Adhesives (ACA). The ACA interconnect technology replaces solder bumps with conductive micro-particles embedded in an epoxy layer applied as either film or paste. The electro-mechanical connection between the sensor and ASIC is achieved via thermocompression of the ACA using a flip-chip device bonder. A specific pixel-pad topology is required to enable the connection via micro-particles and create cavities into which excess epoxy can flow. This pixel-pad topology is achieved with an in-house Electroless Nickel Immersion Gold process that is also under development within the project. The ENIG and ACA processes are qualified with a variety of different ASICs, sensors, and dedicated test structures, with pad diameters ranging from 12 μm to 140 μm and pitches between 20 μm and 1.3 mm. The produced assemblies are characterized electrically, with radioactive-source exposures, and in tests with high-momentum particle beams. A focus is placed on recent optimization of the plating and interconnect processes, resulting in an improved plating uniformity and interconnect yield.

description: Smart home technology is emerging rapidly as an exciting new paradigm. Smart homes have the potential to improve home comfort, convenience, security and energy management. Moreover, it can be used for elderly people and those with disabilities, providing safe and secure environments. GOODIES (GrOup On Development of Intelligent EnvironmentS) is a research group of Middlesex University that is trying to advance this type of technology innovation. We are innovating by developing a personalised intelligent home system that can provide the resident home automation facilities as soon as the resident starts living in the new house. The smart home can provide home automation services from the start instead of aggregating, analysing and processing data which usually take several weeks. This is initial questionnaire which will ask the audience.
Steering transformative energy efficiency and conservation in British Columbia, Canada
Creators: name: Berkhout, Thomas William
Publisher: name: University of British Columbia
Year: 2013

description: In this thesis I assess the strength of efforts by the Government of British Columbia and BC Hydro to steer transformative energy efficiency and conservation (TEEC) in BC’s built environment between 2005 and 2012. TEEC implies a level of energy savings that requires major changes over the next 10 to 40 years in not only the physical components of the built environment but also in day-to-day routines and patterns of life. An underlying assumption of the thesis is that in order to learn about, develop and implement the kinds of initiatives needed to achieve TEEC an accelerated system of policy and technology innovation is required. In carrying out my research, my particular focus was on assessing the influence of governance practices on efforts to achieve TEEC and on the outcomes that these practices lead to. To do this, I developed a theory-based evaluation framework to assess the effectiveness of existing governance approaches to steer socio-technical transitions. The underlying premise of the theory is that a reflexive governance approach to steering transitions is more likely to lead to a stronger transition context which over time increases the likelihood of a transition being achieved. To this end, the thesis singled-out eight system conditions that I argue are needed to build and maintain the kind of momentum needed to realize long-term transformational change in complex socio-technical systems. These eight conditions were then used as the basis for assessing the strengths and weaknesses of the Province’s and BC Hydro’s efforts to steer TEEC. When I compared the strength of the transition conditions being created in each case study against the governance approach used, I found a link between the use of reflexive governance practices and stronger transition conditions. Based on this assessment 15 recommendations were advanced for how to improve the governance of TEEC in BC’s built environment. What is more, these findings suggest that any effort to pursue TEEC will need to also be accompanied by a shift to a more reflexive approach for steering transformational change.
Quantitative analysis of quantum phase slips in superconducting MoGe nanowires revealed by switching-current statistics

description: We measure quantum and thermal phase-slip rates using the standard deviation of the switching current in superconducting nanowires at high bias current. Our rigorous quantitative analysis provides firm evidence for the presence of quantum phase slips (QPS) in homogeneous nanowires. We observe that as temperature is lowered, thermal fluctuations freeze at a characteristic crossover temperature Tq, below which the dispersion of the switching current saturates to a constant value, indicating the presence of QPS. The scaling of the crossover temperature Tq with the critical temperature Tc is linear, which is consistent with the theory of macroscopic quantum tunneling. We can convert the wires from the initial amorphous phase to a single crystal phase, in situ, by applying calibrated voltage pulses. This technique allows us to probe directly the effects of the wire resistance, critical temperature and morphology on thermal and quantum phase slips.

Comments on Non-holomorphic Modular Forms and Non-compact Superconformal Field Theories

description: We extend our previous work arXiv:1012.5721 [hep-th] on the non-compact N=2 SCFT_2 defined as the supersymmetric SL(2,R)/U(1)-gauged WZW model. Starting from path-integral calculations of torus partition functions of both the axial-type (`cigar') and the vector-type (`trumpet') models, we study general models of the Z_M-orbifolds and M-fold covers with an arbitrary integer M. We then extract contributions of the degenerate representations (`discrete characters') in such a way that good modular properties are preserved. The `modular completion' of the extended discrete characters introduced in arXiv:1012.5721 [hep-th] are found to play a central role as suitable building blocks in every model of orbifolds or covering spaces. We further examine a large M-limit (the `continuum limit'), which `deconstructs' the spectral flow orbits while keeping a suitable modular behavior. The discrete part of partition function as well as the elliptic genus is then expanded by the modular completions of irreducible discrete characters, which are parameterized by both continuous and discrete quantum numbers modular transformed in a mixed way. This limit is naturally identified with the universal cover of trumpet model. We finally discuss a classification of general modular invariants based on the modular completions of irreducible characters constructed above.

description: Interactions between soils and climate impact wider environmental sustainability. Soil heterogeneity intricately regulates these interactions over short spatiotemporal scales and therefore needs to be more finely examined. This paper examines how redox heterogeneity at the level of minerals, microbial cells, organic matter, and the rhizosphere entangles biogeochemical cycles in soil with climate change. Redox heterogeneity is used to develop a conceptual framework that encompasses soil microsites (anaerobic and aerobic) and cryptic biogeochemical cycling, helping to explain poorly understood processes such as methanogenesis in oxygenated soils. This framework is further shown to disentangle global carbon (C) and nitrogen (N) pathways that include CO2, CH4, and N2O. Climate-driven redox perturbations are discussed using wetlands and tropical forests as model systems. Powerful analytical methods are proposed to be combined and used more extensively to study coupled abiotic and biotic reactions that are affected by redox heterogeneity. A core view is that emerging and future research will benefit substantially from developing multifaceted analyses of redox heterogeneity over short spatiotemporal scales in soil. Taking a leap in our understanding of soil and climate interactions and their evolving influence on environmental sustainability then depends on greater collaborative efforts to comprehensively investigate redox heterogeneity spanning the domain of microscopic soil interfaces.
