description: We compare dependences between the storm development rate $|Dst_{min}|/ΔT$ ($ΔT$ is the durations of main phase) and the duration of recovery phase of magnetic storms generated by three various types of interplanetary drivers: (1, 2) compression regions CIR and Sheath, and (3) body of interplanetary CME (magnetic clouds and Ejecta). Our analyze shows that the duration of recovery phase correlates with the storm development rate for CIR- and Sheath-induced storms, and does not correlate for ICME- induced storms.

description: Various types of electroweak-interacting particles, which have non-trivial charges under the $\mathrm{SU}(2)_L \times \mathrm{U}(1)_Y$ gauge symmetry, appear in various extensions of the Standard Model. These particles are good targets of future lepton colliders, such as the International Linear Collider (ILC), the Compact LInear Collider (CLIC) and the Future Circular Collider of electrons and positrons (FCC-ee). An advantage of the experiments is that, even if their beam energies are below the threshold of the production of the new particles, quantum effects of the particles can be detected through high precision measurements. We estimate the capability of future lepton colliders to probe electroweak-interacting particles through the quantum effects, with particular focus on the wino, the Higgsino and the so-called minimal dark matters, and found that a particle whose mass is greater than the beam energy by 100-1000 GeV is detectable by measuring di-fermion production cross sections with $O(0.1)$\% accuracy. In addition, with the use of the same analysis, we also discuss the sensitivity of the future colliders to model independent higher dimensional operators, and found that the cutoff scales corresponding to the operators can be probed up to a few ten TeV.

description: While some studies have reported that early age of onset of cannabis and amphetamine use predicts a range of adverse outcomes, these findings are rarely adjusted for other predictors of adverse outcomes or subsequent drug use over the adult life course. These studies have not addressed the possibility that it is subsequent rather than early age of onset of drug use that may predict adult life success. Data are from the Mater-University of Queensland Study of Pregnancy (MUSP). At 21 years, respondents self-reported their use of cannabis and amphetamines and completed the Composite International Diagnostic Interview (CIDI) on lifetime ever use of cannabis and amphetamines. At 30 years, respondents self-reported their past-year use of cannabis and amphetamines. The outcome measure is a composite measure of life success at the 30-years follow-up. Associations are adjusted for covariates at the 14-year follow-up. Adolescent behavior problems predict drug use at 21 years, drug use and life success at 30 years. The association between early age of onset cannabis use, amphetamine use and cannabis and amphetamine use and adult life success is not statistically significant once adjusted for cannabis and amphetamine use at the 30-year follow-up. Concurrent cannabis use at the 30-year follow-up is strongly related to life success. In a community sample, cannabis as well as cannabis and amphetamine use and/or use disorder in the adolescent period does not appear to predict life success in adulthood for those whose use has ceased prior to 30 years of age.

description: We have investigated whether the Scalar-Tensor-Vector Gravity theory (STVG) may explain the kinematic of stars in dwarf spheroidal galaxies. STVG modifies General Relativity by adding extra scalar and vector fields with the main aim of replacing dark matter in astrophysical self-gravitating systems. The weak-field limit of STVG brings a Yukawa-like modification to the Newtonian gravitational potential. The modification is modulated by two parameters, $α$ and $μ$, that represent a redefinition of the gravitational coupling constant and the mass of the additional vector fields, respectively. Thus, adopting the modified gravitational potential arising in the weak-field limit of STVG, we have solved the spherical Jeans equation to predict the line-of-sight velocity dispersion profiles of eight dwarf spheroidal galaxies orbiting around the Milky Way. The predicted profiles are then compared to the data using a Monte Carlo Markov Chain algorithm. Our results pointed out some tensions on the $α$ parameter within the data set, while comparison with previous analysis shows the effectiveness of STVG in replacing dark matter with extra massive fields. Further improvements will require more sophisticated modelling of the line-of-sight velocity dispersion which will be possible as soon as high-precision astrometric data in dwarf spheroidals will become available.

description: The amount of research articles produced every day is overwhelming: scholarly knowledge is getting harder to communicate and easier to get lost. A possible solution is to represent the information in knowledge graphs: structures representing knowledge in networks of entities, their semantic types, and relationships between them. But this solution has its own drawback: given its very specific task, it requires new methods for designing and evaluating user interfaces. In this paper, we propose an approach for user interface evaluation in the knowledge communication domain. We base our methodology on the well-established Cognitive Walkthough approach but employ a different set of questions, tailoring the method towards domain-specific needs. We demonstrate our approach on a scholarly knowledge graph implementation called Open Research Knowledge Graph (ORKG).

description: The hybrid halide perovskite CH3NH3PbI3 exhibits a complex structural behaviour, with successive transitions between orthorhombic, tetragonal and cubic polymorphs at ca. 165 K and 327 K. Herein we report first-principles lattice dynamics (phonon spectrum) for each phase of CH3NH3PbI3. The equilibrium structures compare well to solutions of temperature-dependent powder neutron diffraction. By following the normal modes we calculate infrared and Raman intensities of the vibrations, and compare them to the measurement of a single crystal where the Raman laser is controlled to avoid degradation of the sample. Despite a clear separation in energy between low frequency modes associated with the inorganic PbI3 network and high-frequency modes of the organic CH3NH3+ cation, significant coupling between them is found, which emphasises the interplay between molecular orientation and the corner-sharing octahedral networks in the structural transformations. Soft modes are found at the boundary of the Brillouin zone of the cubic phase, consistent with displacive instabilities and anharmonicity involving tilting of the PbI6 octahedra around room temperature.

description: A key quality of any kind of system is its ability to deliver its respective service correctly. Often the unavailability of commercial systems may lead to lost revenue, which are minor compared to what may be at stake when critical infrastructures fail. A failure to deliver critical services, such as clean water or electricity may have dire consequences that endanger human lives and may even halt or break other infrastructures. The services provided by critical infrastructures need to be supplied continuously even when faced with re-configurations, outside disturbances and systemic changes. A system is called resilient if it fulfils this property. From the many critical infrastructures that exist, power systems may be the most important ones, because they are supplying the required electricity for other critical infrastructures. At the same time, a power system itself may be exposed to several disturbances from internal sources, e.g., fluctuations in the energy demand, and external sources, e.g., heavy storms. Especially, fast dynamic effects caused by these disturbances may lead to deviations of grid frequency, short-circuits, or, in severe cases, a total power system failure. As future scenarios will include more distributed renewable sources and less centralized generation from fossil fuels, ICT-based communication and coordination will play an increasing role. This paper examines the notion of resilience, how it has been traditionally ensured for the power system, and novel approaches to maintain the frequency, protect people and devices against short circuits and recover from a blackout. A special focus is on communication and the role that distributed renewable generation plays for these processes.

description: This talk will describe an experiment to assess whether artificial intelligence (AI) could be used to assign quality scores to journal articles to partly or fully replace expert judges in research assessment exercises. It analyses human peer reviews from the UK Research Excellence Framework 2021 (1*, 2*, 3*, 4*) given to journal articles from all disciplines, but with a focus on physics. Although the results were not accurate enough for the satisfaction of the current peer reviewers, the results could be used to inform peer review, for example by identifying articles that are easy to score or by acting as a tie-breaker when the human judges disagree. An important useful property of the AI solution is its estimation of its own accuracy, so human judges can ignore computer predictions that are very uncertain. This talk will also discuss disciplinary differences in peer review and AI accuracy to give context to the physics AI results.

Creators: name: Shuttleworth, David

Publisher: name: Old Dominion University Libraries
Year: 2023

description: This paper presents preliminary research using Natural Language Processing (NLP) to support the development of conceptual modeling frameworks. NLP-based frameworks are intended to lower the barrier of entry for non-modelers to develop models and to facilitate communication across disciplines considering simulations in research efforts. NLP drives conceptual modeling in two ways. Firstly, it attempts to automate the generation of conceptual models and simulation specifications, derived from non-modelers’ narratives, while standardizing the conceptual modeling process and outcome. Secondly, as the process is automated, it is simpler to replicate and be followed by modelers and non-modelers. This allows for using a common process and generating similar “blueprints” facilitating communication and collaboration efforts. Overall, NLP presents an opportunity for the M&S community to engage with stakeholders and scholars across domains in the simulation development process, lowering entry barriers and increasing participation.

description: Sums of lognormal random variables (RVs) occur in many important problems in wireless communications especially in interferences calculation. Several methods have been proposed to approximate the lognormal sum distribution. Most of them requires lengthy Monte Carlo simulations, or advanced slowly converging numerical integrations for curve fitting and parameters estimation. Recently, it has been shown that the log skew normal distribution can offer a tight approximation to the lognormal sum distributed RVs. We propose a simple and accurate method for fitting the log skew normal distribution to lognormal sum distribution. We use moments and tails slope matching technique to find optimal log skew normal distribution parameters. We compare our method with those in literature in terms of complexity and accuracy. We conclude that our method has same accuracy than other methods but more simple. To further validate our approach, we provide an example for outage probability calculation in lognormal shadowing environment based on log skew normal approximation.

description: Small liver lesions common to colorectal liver metastases (CRLMs) are challenging for convolutional neural network (CNN) segmentation models, especially when we have a wide range of slice thicknesses in the computed tomography (CT) scans. Slice thickness of CT images may vary by clinical indication. For example, thinner slices are used for presurgical planning when fine anatomic details of small vessels are required. While keeping the effective radiation dose in patients as low as possible, various slice thicknesses are employed in CRLMs due to their limitations. However, differences in slice thickness across CTs lead to significant performance degradation in CT segmentation models based on CNNs. This paper proposes a novel unsupervised attention-based interpolation model to generate intermediate slices from consecutive triplet slices in CT scans. We integrate segmentation loss during the interpolation model's training to leverage segmentation labels in existing slices to generate middle ones. Unlike common interpolation techniques in CT volumes, our model highlights the regions of interest (liver and lesions) inside the abdominal CT scans in the interpolated slice. Moreover, our model's outputs are consistent with the original input slices while increasing the segmentation performance in two cutting-edge 3D segmentation pipelines. We tested the proposed model on the CRLM dataset to upsample subjects with thick slices and create isotropic volume for our segmentation model. The produced isotropic dataset increases the Dice score in the segmentation of lesions and outperforms other interpolation approaches in terms of interpolation metrics.

description: We use the class of commuting quantum computations known as IQP (Instantaneous Quantum Polynomial time) to strengthen the conjecture that quantum computers are hard to simulate classically. We show that, if either of two plausible average-case hardness conjectures holds, then IQP computations are hard to simulate classically up to constant additive error. One conjecture relates to the hardness of estimating the complex-temperature partition function for random instances of the Ising model; the other concerns approximating the number of zeroes of random low-degree polynomials. We observe that both conjectures can be shown to be valid in the setting of worst-case complexity. We arrive at these conjectures by deriving spin-based generalisations of the Boson Sampling problem that avoid the so-called permanent anticoncentration conjecture.

Automated Action Selection and Embodied Simulation for Socially Assistive Robots using Standardized Interactions

description: Robots have the tremendous potential of assisting people in their lives, allowing them to achieve goals that they would not be able to achieve by themselves. In particular, sociallyassistive robots provide assistance primarily through social interaction, in healthcare, therapy, and education contexts. Despite their potential, current socially assistive robotsstill lack robust interactive capabilities to allow them to carry out assistive tasks flexibly and autonomously. Some challenges for these robots include responding to and engaging in multi-modal behavior, operating with minimal expert intervention, and accommodating different user needs. Motivated by these challenges, this thesis aims at augmenting the algorithmic capabilities of such robots by leveraging the structure of existing standardized human-human interactions in assistive domains. Using therapy for Autism Spectrum Disorder (ASD) as a domain of focus, we explore two roles for a socially assistive robot: ‘provider’ and‘receiver’. In the provider role, the robot proactively engages in assistive tasks with a human receiver (namely a child with ASD), following standardized interactive tasks. We contribute a family of algorithms for automated action selection, whose goal is to build cost-optimal robot action sequences that account for a range of receiver profiles. We further estimate the action parameters needed to run these algorithms through empirical studies with children with ASD and psychology experts, and show that the algorithms are able to generate personalized action sequences according to different child profiles. In the receiver role, the robot simulates common behavioral responses of children withASD to the standardized actions, acting as an aid for providers in training. By reversing the standardized diagnosis pipeline, we first develop a simulation method that generates behaviors consistent with user-controllable receiver profiles. In a second step, we develop an interactive robot capable of responding to a therapist’s actions in an embodied fashion. Our evaluation studies conducted with therapists validate the designed robot behaviors and show promising results for the integration of such robots in clinical training. These contributions allow for a richer set of interactions with robots in assistive contexts, and are expected to increase their autonomy, flexibility, and effectiveness when dealing with diverse user populations.

description: Despite the proliferation and the increasing coverage of linguistic resources for many modern and historical languages, the interoperability issues imposed by their different formats severely limit their potential for exploitation and use. To address this challenge, the LiLa: Linking Latin ERC-Consolidator project (2018-2023; https://lila-erc.eu) aims to connect the wealth of linguistic resources for Latin developed thus far, by building a Linked Data Knowledge Base of the currently available textual/lexical resources (e.g., corpora, lexica, dictionaries, thesauri) and natural language processing (NLP) tools for Latin, i.e. a collection of several data sets described using the same vocabulary of knowledge description and linked together (Passarotti et al., 2020). Linked Data is a paradigm according to which data in the Semantic Web (Berners-Lee et al., 2001) are interlinked with other data via triple-like connections that can be interrogated via semantic queries. LiLa makes use of a set of Semantic Web and Linguistic Linked Open Data standards, including ontologies to describe linguistic annotation (OLiA: Chiarcos & Sukhareva, 2015), corpus annotation (NIF: Hellmann et al., 2013) and lexical resources (Lemon: Buitelaar et al., 2011). The LiLa Knowledge Base is highly lexically-based, following the assumption that everything in LiLa deals with words. Textual resources are made of (occurrences of) words, lexical resources describe properties of words, and NLP tools process words. The core of the LiLa Knowledge Base is a large collection of Latin lemmas extracted from a number of dictionaries and glossaries for Classical, Late and Medieval Latin, for a total of more than 130,000 lemmas. The Lemma is the key Class in the ontology LiLa is built upon. Interoperability is achieved by linking the entries in lexical resources and the corpus tokens pointing to the same lemma. Our talk wants to introduce the LiLa Knowledge Base, particularly detailing (a) the structure of its collection of lemmas and (b) the inclusion into LiLa, as well as the use through LiLa, of a number of linguistic resources, including some for Late and Vulgar Latin, like a portion of the Computational Historical Semantics corpus (https://www.comphistsem.org/home.html) and the Late Latin Charter Treebank (Korkiakangas & Passarotti, 2011).
Online Inference of Joint Occupancy using Forward Sensor Models and Trajectory Posteriors for Deliberate Robot Navigation

description: Robotic navigation algorithms for real-world robots require dense and accurate probabilistic volumetric representations of the environment in order to traverse efficiently. Sensor data in a Simultaneous Localisation And Mapping (SLAM)context, however, always has associated acquisition noise and pose uncertainty, and encoding this within the map representation while still maintaining computationaltractability is a key challenge in deploying these systems outside of controlled laboratory settings. The occupancy inference problem is essentially a high dimensional searchin the space of all maps. By incorporating the physics of sensor formation using forward models, it is possible to reason in terms of the likelihood of the measurements for a given map hypothesis to obtain a solution that explainsthe noisy observations as well as possible. However, this approach to mapping has historically been prohibitively expensive to compute in real-time. Thus, conventional robotic mapping algorithms have primarily chosen to work with limiting assumptions to maintain tractability.In this thesis we present a framework that explicitly reasons about the conditional dependence imposed on the occupancy of voxels traversed by each ray of a depth camera as a Markov Random Field (MRF). The tight intra-and inter-ray coupling explicitly incorporates conditional dependence of the occupancy of individual voxels as opposed to making independent log-odds Bayes filterupdates as conventional occupancy maps do. Visibility constraints imposed by using a forward sensor model enables simplification of the otherwise high dimensional inference. The forward model allows incorporating learnt sensor noise characteristics for accurate inference. Instead of marginalising sensor data immediately, data from camera poses is retained, and can be added, moved, or removed in an ad-hoc fashion whilst performing inference. In order to avoid prohibitive sensor data storage costs, an extension to using the framework in a submapping setting with pose graphs is presented with sensor data marginalisationdeferred until as late as possible. Marginalisation is performed using succinct parametric Gaussian distribution representations. Finally, Gaussian mixture model map representations are then demonstrated to be capable ofproviding robust localisation in multi-hypothesis settings. All of this is made real-time feasible by the inherent parallelisability of the proposed framework and is implemented on GPUs.

description: A central question in quantum information theory is to determine how well lost information can be reconstructed. Crucially, the corresponding recovery operation should perform well without knowing the information to be reconstructed. In this work, we show that the quantum conditional mutual information measures the performance of such recovery operations. More precisely, we prove that the conditional mutual information $I(A:C|B)$ of a tripartite quantum state $ρ_{ABC}$ can be bounded from below by its distance to the closest recovered state $\mathcal{R}_{B \to BC}(ρ_{AB})$, where the $C$-part is reconstructed from the $B$-part only and the recovery map $\mathcal{R}_{B \to BC}$ merely depends on $ρ_{BC}$. One particular application of this result implies the equivalence between two different approaches to define topological order in quantum systems.

description: Response functions of infinite nuclear matter with arbitrary isospin asymmetry are studied in the framework of the random phase approximation. The residual interaction is derived from a general nuclear Skyrme energy density functional. Besides the usual central, spin-orbit and tensor terms it could also include other components as new density-dependent terms or three-body terms. Algebraic expressions for the response functions are obtained from the Bethe-Salpeter equation for the particle-hole propagator. Applications to symmetric nuclear matter, pure neutron matter and asymmetric nuclear matter are presented and discussed. Spin-isospin strength functions are analyzed for varying conditions of density, momentum transfer, isospin asymmetry, and temperature for some representative Skyrme functionals. Particular attention is paid to the discussion of instabilities, either real or unphysical, which could manifest in finite nuclei.

description: A search for neutrinoless $ββ$ decay processes accompanied with Majoron emission has been performed using data collected during Phase I of the GERmanium Detector Array (GERDA) experiment at the Laboratori Nazionali del Gran Sasso of INFN (Italy). Processes with spectral indices n = 1, 2, 3, 7 were searched for. No signals were found and lower limits of the order of 10$^{23}$ yr on their half-lives were derived, yielding substantially improved results compared to previous experiments with $^{76}$Ge. A new result for the half-life of the neutrino-accompanied $ββ$ decay of $^{76}$Ge with significantly reduced uncertainties is also given, resulting in $T^{2ν}_{1/2} = (1.926 \pm 0.095)\cdot10^{21}$ yr.

description: While modern society benefits from a range of technological advancements, it also is exposed to an ever-increasing set of cybersecurity threats. These affect all areas of life including business, government, and individuals. To complement technology solutions to this problem, it is crucial to understand more about cybercriminal perpetrators themselves, their use of technology, psychological aspects, and profiles. This is a topic that has received little socio-technical research emphasis in the technology community, has few concrete research findings, and is thus a prime area for development. The aim of this article is to explore cybercriminal activities and behavior from a psychology and human aspects perspective, through a series of notable case studies. We examine motivations, psychological and other interdisciplinary concepts as they may impact/influence cybercriminal activities. We expect this paper to be of value and particularly insightful for those studying technology, psychology, and criminology, with a focus on cybersecurity and cybercrime.

description: In this paper, we investigate the equilibrium statistical properties of both the force and potential interpolations of adaptive resolution simulation (AdResS) under the theoretical framework of grand-canonical like AdResS (GC-AdResS). The thermodynamic relations between the higher and lower resolutions are derived by considering the absence of fundamental conservation laws in mechanics for both branches of AdResS. In order to investigate the applicability of AdResS method in studying the properties beyond the equilibrium, we demonstrate the accuracy of AdResS in computing the dynamical properties in two numerical examples: The velocity auto-correlation of pure water and the conformational relaxation of alanine dipeptide dissolved in water. Theoretical and technical open questions of the AdResS method are discussed in the end of the paper.

description: We are carrying out a series of photometric monitoring to measure the rotation periods of members in the young $β$ Pictoris Association, as part of the RACE-OC project (Rotation and ACtivity Evolution in Open Clusters). In this paper, we present the results for HD 155555C which is believed to be physically associated to the spectroscopic binary V824 Ara (HD155555) and thus constituting a triple system. We collected B, V, and R-band photometric data timeseries and discovered from periodogram analysis the rotation period P = 4.43d. Combined with stellar radius and projected rotational velocity, we find this star almost equator-on with an inclination $i$ $\simeq$ 90$^{\circ}$. The rotational properties of HD155555C fit well into the period distribution of other $β$ Pic members, giving further support to the suggested membership to the association and to its physical association to V824 Ara. A comparison with Pre-Main-Sequence isochrones from various models allows us to estimate an age of 20$\pm$15 Myr for this triple system.

description: Time-resolved illumination provides rich spatio-temporal information for applications such as accurate depth sensing or hidden geometry reconstruction, becoming a useful asset for prototyping and as input for data-driven approaches. However, time-resolved illumination measurements are high-dimensional and have a low signal-to-noise ratio, hampering their applicability in real scenarios. We propose a novel method to compactly represent time-resolved illumination using mixtures of exponentially-modified Gaussians that are robust to noise and preserve structural information. Our method yields representations two orders of magnitude smaller than discretized data, providing consistent results in applications such as hidden scene reconstruction and depth estimation, and quantitative improvements over previous approaches.

description: The analysis of the electronic properties of strained or lattice deformed graphene combines ideas from classical condensed matter physics, soft matter, and geometrical aspects of quantum field theory (QFT) in curved spaces. Recent theoretical and experimental work shows the influence of strains in many properties of graphene not considered before, such as electronic transport, spin-orbit coupling, the formation of Moiré patterns, optics, ... There is also significant evidence of anharmonic effects, which can modify the structural properties of graphene. These phenomena are not restricted to graphene, and they are being intensively studied in other two dimensional materials, such as the metallic dichalcogenides. We review here recent developments related to the role of strains in the structural and electronic properties of graphene and other two dimensional compounds.

Weak values in continuous weak measurement of qubits

description: For continuous weak measurement of qubits, we obtain exact expressions for weak values (WVs) from the post-selection restricted average of measurement outputs, by using both the quantumtrajectory- equation (QTE) and quantum Bayesian approach. The former is applicable to short-time weak measurement, while the latter can relax the measurement strength to finite. We find that even in the "very" weak limit the result can be essentially different from the one originally proposed by Aharonov, Albert and Vaidman (AAV), in a sense that our result incorporates non-perturbative correction which could be important when the AAV's WV is large. Within the Bayesian framework, we obtain also elegant expressions for finite measurement strength and find that the amplifier's noise in quantum measurement has no effect on the WVs. In particular, we obtain very useful result for homodyne measurement in circuit-QED system, which allows for measuring the real and imaginary parts of the AAV's WV by simply tuning the phase of the local oscillator. This advantage can be exploited as efficient state-tomography technique.

description: The neural substrates of visual categories have been the subject of an increasing number of neurophysiological studies. Categorization tasks are often used as a tool, in these studies, to induce well-defined categories via behavioral training. Here, we highlight the important difference between the neuronal substrates underlying perceptual versus behavioral categories. To illustrate this distinction, we examine a recently reported study of the neural representation of motion categories. Using a simple model of categorical perception, we identify potential neural signatures of perceptual motion categories. Our exercise indicates that the neural correlates of categorical motion perception can be subtler than the binary response profile that is often treated as the litmus test of visual categorization.

description: Almost all optimization algorithms have algorithm-dependent parameters, and the setting of such parameter values can largely influence the behaviour of the algorithm under consideration. Thus, proper parameter tuning should be carried out to ensure the algorithm used for optimization may perform well and can be sufficiently robust for solving different types of optimization problems. This chapter reviews some of the main methods for parameter tuning and then highlights the important issues concerning the latest development in parameter tuning. A few open problems are also discussed with some recommendations for future research.

description: Many inverse and parameter estimation problems can be written as PDE-constrained optimization problems. The goal, then, is to infer the parameters, typically coefficients of the PDE, from partial measurements of the solutions of the PDE for several right-hand-sides. Such PDE-constrained problems can be solved by finding a stationary point of the Lagrangian, which entails simultaneously updating the paramaters and the (adjoint) state variables. For large-scale problems, such an all-at-once approach is not feasible as it requires storing all the state variables. In this case one usually resorts to a reduced approach where the constraints are explicitly eliminated (at each iteration) by solving the PDEs. These two approaches, and variations thereof, are the main workhorses for solving PDE-constrained optimization problems arising from inverse problems. In this paper, we present an alternative method that aims to combine the advantages of both approaches. Our method is based on a quadratic penalty formulation of the constrained optimization problem. By eliminating the state variable, we develop an efficient algorithm that has roughly the same computational complexity as the conventional reduced approach while exploiting a larger search space. Numerical results show that this method indeed reduces some of the non-linearity of the problem and is less sensitive the initial iterate.
