description: Three generation heterotic-string vacua in the free fermionic formulation gave rise to models with solely the MSSM states in the observable Standard Model charged sector. The relation of these models to Z_2 x Z_2 orbifold compactifications dictates that they produce three pairs of untwisted Higgs multiplets. The reduction to one pair relies on the analysis of supersymmetric flat directions, that give superheavy mass to the dispensable Higgs states. We explore the removal of the extra Higgs representations by using the free fermion boundary conditions and hence directly at the string level, rather than in the effective low energy field theory. We present a general mechanism that achieves this reduction by using asymmetric boundary conditions between the left- and right-moving internal fermions. We incorporate this mechanism in explicit string models containing three twisted generations and a single untwisted Higgs doublet pair. We further demonstrate that an additional effect of the asymmetric boundary conditions is to substantially reduce the supersymmetric moduli space.

title:  Costruire ponti per ri-narrare identità di uomini e di città

description: L’identità narrativa è forse il concetto più noto dell’investigazione ricœuriana attraverso cui dar conto delle aporie di una soggettività vissuta e incarnata e di una alterità difficilmente comprensibile. Nella dialettica fra medesimezza e ipseità, fra soggettività e alterità, fra attività e passività, la narrazione offre una opportunità per cucire gli strappi fra sé e sé e fra le tante relazioni che ci costituiscono. Narrare per sedare tensioni e per sciogliere incomprensioni, ‘costruire testi’ per trovare nelle parole ‘scritte’ come nelle parole ‘dette’ suggerimenti e soluzioni poetiche alle tante problematiche che affliggono i popoli. Scrivere storie che è possibile ‘leggere’ come racconti di fatiche ma anche di rinascite. Ecco perché Ricœur tenta un innesto interessante fra narrazione e architettura, fra le identità di un popolo e le fisionomie di città. Riuscire a leggere le città come testi significa ‘vedere’ lo spazio cittadino come metafora di una identità complessa, in cui la diversità compromette e altera lo statuto stesso del soggetto, che spesso necessita di dirsi e di narrarsi per non smarrirsi del tutto.

description: The Josephson current-phase characteristics, that arise when a supercurrent flows across two fermionic superfluids separated by a potential barrier, can be controlled by varying either the inter-particle coupling or the temperature. While the coupling dependence has been addressed in detail both theoretically and experimentally for an attractive Fermi gas undergoing the BCS-BEC crossover, a corresponding study of the temperature dependence of the Josephson characteristics is still lacking in this context. Here, we investigate the combined coupling and temperature dependence of the Josephson characteristics in a systematic way for a wide set of barriers, within ranges of height and width that can be experimentally explored. Our study smoothly connects the two limiting cases, of non-overlapping composite bosons at low temperature described by the Gross-Piatevskii equation, and of strongly overlapping Cooper pairs near the critical temperature described by the Ginzburg-Landau equation. In this way, we are able to explore several interesting effects related to how the current-phase characteristics evolve along the BCS-BEC crossover as a function of temperature and of barrier shape. These effects include the coherence length outside the barrier and the pair penetration length inside the barrier (which is related to the proximity effect), as well as the temperature evolution of the Landau criterion in the limit of a vanishingly small barrier. A comparison is also presented between the available experimental data for the critical current and our theoretical results over a wide range of couplings along the BCS-BEC crossover.

description: We aim to see whether debris belts evolving in between two stars may be impacted by the presence of the companion and whether this leaves any detectable signature that could be observed with current or future instruments. We consider a circumprimary parent body (PB) planetesimal belt that is placed just inside the stability limit between the 2 stars and use the DyCoSS code to follow the coupled dynamical and collisional evolution of the dust produced by this PB belt. We explore several free parameters such as the belt's mass or the binary's mass ratio and orbit. We use the GraTeR package to produce 2-D luminosity maps and system-integrated SEDs. We confirm a preliminary result obtained by earlier DyCoSS studies, which is that the coupled effect of collisional activity, binary perturbations and stellar radiation pressure maintains a halo of small grains in the dynamically unstable region between the 2 stars. In addition, several spatial structures are identified, notably a single spiral arm stretching all the way from the PB belt to the companion star. We also identify a fainter and more compact disc around the secondary star, which is non-native and feeds off small grains from the unstable halo. Both the halo, spiral arm and secondary disc should be detectable on resolved images by instruments with capacities similar to SPHERE. The system as a whole is depleted in small grains when compared to a companion-free case. This depletion leaves an imprint on the system's integrated SED, which appears colder than for the same parent body belt around a single star. This new finding could explain why the SED-derived location $r_{disc}$ of some unresolved discs-in-binaries places their primary belt in the dynamically "forbidden" region between the 2 stars: this apparent paradox could indeed be due to overestimating $r_{disc}$ when using empirical prescriptions valid for a single star case

Calculated excitation energies, electromagnetic transitions and branching ratios are compared with available experimental data and a good agreement is obtained. The model wave functions have been used to study $β$-decays from Ho to Dy isotones, and the calculated $\log ft$ values are close to the experimental data.

description: We present Supervision by Registration and Triangulation (SRT), an unsupervised approach that utilizes unlabeled multi-view video to improve the accuracy and precision of landmark detectors. Being able to utilize unlabeled data enables our detectors to learn from massive amounts of unlabeled data freely available and not be limited by the quality and quantity of manual human annotations. To utilize unlabeled data, there are two key observations: (1) the detections of the same landmark in adjacent frames should be coherent with registration, i.e., optical flow. (2) the detections of the same landmark in multiple synchronized and geometrically calibrated views should correspond to a single 3D point, i.e., multi-view consistency. Registration and multi-view consistency are sources of supervision that do not require manual labeling, thus it can be leveraged to augment existing training data during detector training. End-to-end training is made possible by differentiable registration and 3D triangulation modules. Experiments with 11 datasets and a newly proposed metric to measure precision demonstrate accuracy and precision improvements in landmark detection on both images and video. Code is available at https://github.com/D-X-Y/landmark-detection.

description: The unprecedented precision of atom interferometry will soon lead to laboratory tests of general relativity to levels that will rival or exceed those reached by astrophysical observations. We propose such an experiment that will initially test the equivalence principle to 1 part in 10^15 (300 times better than the current limit), and 1 part in 10^17 in the future. It will also probe general relativistic effects--such as the non-linear three-graviton coupling, the gravity of an atom's kinetic energy, and the falling of light--to several decimals. Further, in contrast to astrophysical observations, laboratory tests can isolate these effects via their different functional dependence on experimental variables.

description: Recording the fluorescence of a magneto-optical trap (MOT) is a standard tool for measuring atom numbers in experiments with ultracold atoms. When trapping few atoms in a small MOT, the emitted fluorescence increases with the atom number in discrete steps, which allows to measure the atom number with single-particle resolution. Achieving such single particle resolution requires stringent minimization of stray light from the MOT beams, which is very difficult to achieve in experimental setups that require in-vacuum components close to the atoms. Here, we present a modified scheme that addresses this issue: Instead of collecting the fluorescence on the MOT (D2) transition, we scatter light on an additional probing (D1) transition and collect this fluorescence with a high-resolution microscope while filtering out the intense MOT light. Using this scheme, we are able to reliably distinguish up to 17 $^{40}$K atoms with an average classification fidelity of 95 \%.

description: In recent work we showed that, for a class of conformal field theories (CFT) with Gauss-Bonnet gravity dual, the shear viscosity to entropy density ratio, $η/s$, could violate the conjectured Kovtun-Starinets-Son viscosity bound, $η/s\geq1/4π$. In this paper we argue, in the context of the same model, that tuning $η/s$ below $(16/25)(1/4π)$ induces microcausality violation in the CFT, rendering the theory inconsistent. This is a concrete example in which inconsistency of a theory and a lower bound on viscosity are correlated, supporting the idea of a possible universal lower bound on $η/s$ for all consistent theories.

description: We report the first demonstration to our knowledge of a continuously tunable picosecond laser operating around 1 MHz. The emission can be tuned from 640 to 685 nm and the repetition rate from 200 kHz to 1 MHz with a pulse duration of less than 200 ps. The system is based on a Nd:YVO4 passively Q-switched microchip laser providing a few tens of nJ per pulse. Two cascaded stages of amplification are then used to increase the pulse energy to several microJ . The frequency doubled radiation is then used to pump a periodically-poled-niobate-lithium (PPLN)-based optical parametric generator in an all-solid-state architecture. 20 nJ of tunable signal radiation are obtained. We also demonstrated 300-ps pulses generation in the UV (355 nm) at 1 MHz.
Joint Denoising and Demosaicking with Green Channel Prior for Real-world Burst Images

description: Denoising and demosaicking are essential yet correlated steps to reconstruct a full color image from the raw color filter array (CFA) data. By learning a deep convolutional neural network (CNN), significant progress has been achieved to perform denoising and demosaicking jointly. However, most existing CNN-based joint denoising and demosaicking (JDD) methods work on a single image while assuming additive white Gaussian noise, which limits their performance on real-world applications. In this work, we study the JDD problem for real-world burst images, namely JDD-B. Considering the fact that the green channel has twice the sampling rate and better quality than the red and blue channels in CFA raw data, we propose to use this green channel prior (GCP) to build a GCP-Net for the JDD-B task. In GCP-Net, the GCP features extracted from green channels are utilized to guide the feature extraction and feature upsampling of the whole image. To compensate for the shift between frames, the offset is also estimated from GCP features to reduce the impact of noise. Our GCP-Net can preserve more image structures and details than other JDD methods while removing noise. Experiments on synthetic and real-world noisy images demonstrate the effectiveness of GCP-Net quantitatively and qualitatively.

description: Aims: The production of molecular hydrogen and its deuterated forms onto carbonaceous dust grains is investigated in detail. The goal of this study is to estimate the importance of the chemistry occuring on grain surfaces for the deuteration of H2. Furthermore, we aim to find a robust and general surface chemical model which can be used in different astrophysical environments. Methods: Surface processes are described for the cases of graphitic and amorphous--carbon grains, where laboratory work is available. Langmuir--Hinshelwood as well as Eley--Rideal surface chemistries are included in the model and their relative contributions are highlighted. Analytic expressions are derived for H2, HD, and D2 formation efficiencies for both type of grains. Rate equations are tested against stochastic methods. Results: As expected, rate equations and stochastic methods diverge for grain sizes lower than a critical value acrit. For grain sizes below this critical value, D2 formation decreases to favour HD formation. The formation efficiencies of H2 and D2 can be calculated by adding a correction factor to the rate equations methods. We found that because of the presence of chemisorbed sites, which can store atoms to form molecules up to high grain temperatures, the formation efficiency of HD and D2 is very high compared to models where only physisorption sites are taken into account. When considering a realistic distribution of dust grains, we found that the formation rate of H2 and HD is enhanced by an order of magnitude if small grains are taken into account. The processes described in this paper, that allow a strong enhancement of the deuterated forms of molecular hydrogen, could explain the high degree of deuterium fractionation observed in protostellar environments.

description: Conventional nonlinear subspace learning techniques (e.g., manifold learning) usually introduce some drawbacks in explainability (explicit mapping) and cost-effectiveness (linearization), generalization capability (out-of-sample), and representability (spatial-spectral discrimination). To overcome these shortcomings, a novel linearized subspace analysis technique with spatial-spectral manifold alignment is developed for a semi-supervised hyperspectral dimensionality reduction (HDR), called joint and progressive subspace analysis (JPSA). The JPSA learns a high-level, semantically meaningful, joint spatial-spectral feature representation from hyperspectral data by 1) jointly learning latent subspaces and a linear classifier to find an effective projection direction favorable for classification; 2) progressively searching several intermediate states of subspaces to approach an optimal mapping from the original space to a potential more discriminative subspace; 3) spatially and spectrally aligning manifold structure in each learned latent subspace in order to preserve the same or similar topological property between the compressed data and the original data. A simple but effective classifier, i.e., nearest neighbor (NN), is explored as a potential application for validating the algorithm performance of different HDR approaches. Extensive experiments are conducted to demonstrate the superiority and effectiveness of the proposed JPSA on two widely-used hyperspectral datasets: Indian Pines (92.98\%) and the University of Houston (86.09\%) in comparison with previous state-of-the-art HDR methods. The demo of this basic work (i.e., ECCV2018) is openly available at https://github.com/danfenghong/ECCV2018_J-Play.
Resonance Raman studies of TTF-TCNQ

Publisher: name: University of British Columbia
Year: 2009

description: The resonant Raman spectra of powder samples of protonated, partially and fully deuterated TTF - TCNQ and protonated TSeF - TCNQ have been measured as a function of temperature (10K-295K) using a Brucker RFS 100 spectrometer with an infrared laser. A number of previously unobserved lines appear in the spectra of TTF - TCNQ below approximately 200 K . The intensity of these lines increases with decreasing temperature. However they show no discontinuity at the three phase transtions, which establish the three-dimensional order of the fluctuating charge - density - wave (CDW) in TTF - TCNQ . These new lines are assigned to the normally Raman - inactive (and infrared - active) B3u modes on the basis of the measured isotopic shifts. The appearance of these B3u out-of- plane intramolecular distortion modes of the TCNQ molecule are in agreement with the results of a recent x-ray study which found that such out-of plane distortions of the TCNQ molecule occur with the appearance of the CDW on the TCNQ chain. Only the intramolecular modes of the TCNQ molecule are resonant and thus observed. A few of the new lines also appear in the low - temperature spectra of TSeF - TCNQ but are generally much weaker in intensity.

We find that only one type of diagram contributes to the effective potential for the Higgs boson in fact and its magnitude is finite.

description: Recent developments in empirical research within the past decade have shown a greater interest in sources of data. Two different directions are observed. On the one hand, deeper granularity is becoming more important. This covers providing statistical information and indicator values beyond NUTS 2 level aiming at using geo-coded statistical data. On the other hand, new data sources, often called big data, are of growing interest to researchers. Both fields urge the need for (further) developing adequate statistical models to draw inference. Additionally, the type and amount of data yields new challenges such as algorithmic problems due to the complexity as well as confidentiality problems. The latter often causes restrictions for data access and, hence, hampers independent research. The Covid pandemic has shown how important data access is nowadays to enable quick, reliable, and independent research in order to support evidence-based policy.

description: Accurate ab initio calculations of 3d transition metal monoxide molecules have attracted extensive attention because of its relevance in physical and chemical science, as well as theoretical challenges in treating strong electron correlation. Meanwhile, recent years have witnessed the rapid development of full configuration interaction quantum Monte Carlo (FCIQMC) method to tackle electron correlation. In this study, we carry out FCIQMC simulations to ScO, TiO and VO molecules and obtain accurate descriptions of 13 low-lying electronic states (ScO $^2Σ^+$, $^2Δ$, $^2Π$; TiO $^3Δ$, $^1Δ$, $^1Σ^+$, $^3Π$, $^3Φ$; VO $^4Σ^-$, $^4Φ$, $^4Π$, $^2Γ$, $^2Δ$), including states that have significant multi-configurational character. The FCIQMC results are used to assess the performance of several other wave function theory and density functional theory methods. Our study highlights the challenging nature of electronic structure of transition metal oxides and demonstrates FCIQMC as a promising technique going forward to treat more complex transition metal oxide molecules and materials.

description: Formula 1 (F1) has embarked on sustainability initiatives, notably the 'Countdown to Zero' campaign aimed at achieving carbon neutrality by 2030. This article delves into F1's sustainability efforts, focusing on the integration of green hydrogen as a promising solution for reducing carbon emissions, particularly within the Middle East and North Africa (MENA) region. Despite the novelty of green hydrogen in F1, its potential applications in powering vehicles and supporting event logistics are explored. Additionally, the article examines MENA's significance in F1's sustainability agenda, given its abundant renewable energy resources and strategic position in hosting Grand Prix races. The feasibility of transitioning F1 cars to sustainable alternatives, including electric vehicles, hydrogen-powered cars, and e-fuels, is scrutinized, highlighting challenges and opportunities. Furthermore, the article discusses sustainable practices that can make F1 events more sustainable. It refers to sustainable practices previously implemented in past F1 Grand Prix races, assesses their applicability to the MENA region, and suggests innovative practices that the MENA can implement; these include the installation of solar canopies in F1 circuit parking lots and the use of bio-fuelled trucks for event logistics. Investment in sustainable aviation fuel (SAF) emerges as another avenue for F1 to mitigate its carbon footprint, potentially through partnerships with airlines present in the MENA region, such as Emirates. Ultimately, this article underscores the imperative for F1 to embrace sustainable practices, not only to align with societal trends but also to lead the charge in environmental stewardship within the realm of motorsport.

description: Dal 2012, cioè dall’anno della celebrazione del World Urban Forum da parte di UN-Habitat a Napoli, la Rivista BDC ha cercato di contribuire alla riflessione sulla “Città di cui abbiamo bisogno”, interpretando i processi urbanizzativi in atto e identificando possibili prospettive di ricerca, capaci di migliorare la qualità della vita nelle città. Ad esempio, già nel vol. 12 del 2012, veniva riportata la Dichiarazione sulla “città circolare”, a conclusione dei dibattiti tenutisi nel WUF (cfr. BDC, vol. 12, n. 1, 2012, pagg. 19-34). In un certo qual modo, i contributi della Rivista hanno collaborato nel lavoro di riflessione nel quadro delle attività della World Urban Campaign che poi nel 2015 hanno portato alla definizione dell’Obiettivo n. 11 della Agenda 2030: realizzare “città inclusive, resilienti, sicure e sostenibili”. Certamente, il dibattito internazionale su approcci, metodi e strumenti per realizzare concretamente l’Obiettivo n. 11 ed i relativi targets continua tutt’oggi ad essere molto vivace. Come migliorare l’inclusione sociale nella città che vede crescere di anno in anno la frammentazione sociale al proprio interno, e quindi le disuguaglianze tra soggetti ricchi e moltitudine di marginali? Quale sostenibilità se manca il lavoro? Come garantire la resilienza nel cambiamento accelerato?

Canadian policy toward foreign direct investment in an age of globalization
Creators: name: Malminen, Johannes.
Publisher: name: University of British Columbia

description: The process of globalization has, since World War II, transformed relations between states, and between states and multinational enterprises (MNEs). Canada was one of the first countries to be transformed by this process - a trail-blazer particularly with respect to foreign direct investment (FDI). This thesis argues that Canada consciously took a globalist approach in its economic development via its openness toward, and active encouragement of, FDI. Canada's approach was facilitated by many factors, notably its cultural and historical ties to the U.K. and the U.S., its immigrant citizenry, and its muted nationalism. This approach, while novel at the time of its institution, has been replicated by states around the world in the last twenty-five years as globalization of the world market has accelerated. The Canadian case is of interest, however, because just at the time when other countries were shifting towards the more liberal and globalist approach to FDI that Canada had championed, Canada changed course and implemented stringent restrictions on FDI. Then, hardly a decade later, Canada returned to a more liberal and open approach to FDI regulation. This thesis argues that Canada turned away from the globalizing trend because foreign penetration of the Canadian economy had become, by far, the highest in the world. This fact, united with anti-American sentiments and a Trudeau-inspired rise in nationalism, set the stage for a dramatic increase in protectionist restrictions, in particular the creation of the Foreign Investment Review Agency (FIRA) in 1974. The election victory of the Conservatives in 1984 and the subsequent abolishment of FIRA symbolizes Canada's return to a globalist approach to its economic well-being. This thesis will argue that Canada's lapse into protectionism collapsed because Canada was out of step with liberalizing global trends and the costs of this, in terms of general welfare, were too high to be borne by a small country, particularly one whose economy had historically relied so heavily on foreign investment.
WASTESCAPES IN PORT CITIES. NAPLES AND ROTTERDAM: A SPATIAL AND INSTITUTIONAL COMPARISON ON THE ROLE OF PORTS AS PROMOTERS OF CIRCULAR ECONOMY

description: Ports have historically followed a linear model of growth. Formation, expansion, reallocation, abandonment, and redevelopments are just some of the steps that are followed over time by ports from all over the world. Circularity – a goal that both ports and cities hope to achieve in the near future – is not a new topic anymore. Although the global pressures to achieve this goal are immense, it can be stated that most port cities still have not yet made serious steps towards new circular models of growth. On the contrary, ports are still expanding, and they still generate serious amounts of waste, while also leaving networks of left-over territories that lay in states of wastefulness: port-city wastescapes. Two cases regarding these wastescapes are discussed. Naples, which is used to show land in limbo, while Rotterdam is used to show a port in transition. This article argues that a circular regeneration of these wastescapes can play a crucial role in re-imagining a new form of integration between the port, the city, and the metropolitan territory. Keywords: wastescapes, port-city, circular economy

description: We explore the dissipative dynamics of nonlinearly driven oscillator systems tuned to resonances where multiple excitations are generated. Such systems are readily realised in circuit QED systems combining Josephson junctions with a microwave cavity and a drive achieved either through flux or voltage bias. For resonances involving 3 or more photons the system undergoes a sequence of two closely spaced dynamical transitions (the first one discontinuous and the second continuous) as the driving is increased leading to steady states that form complex periodic structures in phase space. In the vicinity of the transitions the system displays interesting bistable behaviour: we find that coherent effects can lead to surprising oscillations in the weight of the different dynamical states in the steady state of the system with increasing drive. We show that the dynamics is well-described by a simple effective rate model with transitions between states localised at different points in the phase space crystal. The oscillations in the weights of the dynamical states is reflected in corresponding oscillations in a time-scale that describes transitions between the states.

description: Using a series of high-resolution N-body simulations of the concordance cosmology we investigate how the formation histories, shapes and angular momenta of dark-matter haloes depend on environment. We first present a classification scheme that allows to distinguish between haloes in clusters, filaments, sheets and voids in the large-scale distribution of matter. This method is based on a local-stability criterion for the orbits of test particles and closely relates to the Zel'dovich approximation. Applying this scheme to our simulations we then find that: i) Mass assembly histories and formation redshifts strongly depend on environment for haloes of mass M

description: In contrast to classical systems, actual implementation of non-Hermitian Hamiltonian dynamics for quantum systems is a challenge because the processes of energy gain and dissipation are based on the underlying Hermitian system-environment dynamics that is trace preserving. Recently, a scheme for engineering non-Hermitian Hamiltonians as a result of repetitive measurements on an anicillary qubit has been proposed. The induced conditional dynamics of the main system is described by the effective non-Hermitian Hamiltonian arisng from the procedure. In this paper we demonstrate the effectiveness of such a protocol by applying it to physically relevant multi-spin models, showing that the effective non-Hermitian Hamiltonian drives the system to a maximally entangled stationary state. In addition, we report a new recipe to construct a physical scenario where the quantum dynamics of a physical system represented by a given non-Hermitian Hamiltonian model may be simulated. The physical implications and the broad scope potential applications of such a scheme are highlighted.

description: We investigate the so-called non-resonant cosmic-ray streaming instability, first discussed by Bell (2004). The extent to which thermal damping and ion-neutral collisions reduce the growth of this instability is calculated. Limits on the growth of the non-resonant mode in SN1006 and RX J1713.7-3946 are presented.

description: The goal of this study is to assess the impact of the stellar spots on the extraction of the planetary transmission spectra observed by ARIEL. We develop a method to model the stellar spectrum of a star in the presence of spots by using the out-of-transit observations. It is based on a chi squared minimization procedure of the out-of-transit spectrum on a grid of stellar spectra with different sizes and temperatures of the spots. The approach allows us also to study the temporal evolution of the spots when comparing stellar spectra observed at different epochs. We also present a method to correct the transit depth variations due to non-occulted stellar spots and estimate the error we introduce if we apply the same correction to crossings over the stellar spots. The method is tested on three types of stellar targets that ARIEL will observe in its 4-years mission lifetime. In all the explored cases, the approach allows to reliably recover the spot parameters (size and temperature) from out-of-transit observations and, for non-occulted spots, to confidently recover the planetary atmosphere transmission spectrum within the noise level(with average uncertainty of at most 3.3% of the planetary signal). Conversely, we find systematic biases in the inferred planetary spectra due to the occulted spots, with measurable effects for the brightest targets especially for more contrasted spots.

Unusual effects of magnetic dilution in the ferrimagnetic columnar ordered $\mathrm{Sm_2MnMnMn_{4-x}Ti_xO_{12}}$ perovskites

description: Powder neutron diffraction experiments have been employed to establish the effects of site-selective magnetic dilution in the Sm2MnMnMn4-x Tix O12 A-site columnar ordered quadruple perovskite manganites (x = 1, x = 2 and x = 3). We show that in all three compositions the Mn ions adopt a collinear ferrimagnetic structure below 27 K, 62 K and 34 K, respectively. An unexpected increase in the ordering temperature was observed between the x = 1 and x = 2 samples, which indicates a considerable departure from mean field behaviour. This result is corroborated by large reductions in the theoretical ground state magnetic moments observed across the series, which indicate the presence of spin fluctuations and or disorder. We show that long range magnetic order in the x = 3 sample, which occurs below the percolation threshold for B-B exchange, can only be understood to arise if magnetic order in Sm2MnMnMn4-xTixO12 is mediated via both A-B and B-B exchange, hence confirming the importance of A-B exchange interactions in these materials. Finally we show that site-selective magnetic dilution enables the tuning of a ferrimagnetic compensation point and the introduction of temperature-induced magnetization reversal.
