description: A critical factor in the success of decision support systems is the accurate modeling of user preferences. Psychology research has demonstrated that users often develop their preferences during the elicitation process, highlighting the pivotal role of system-user interaction in developing personalized systems. This paper introduces a novel approach, combining Large Language Models (LLMs) with Constraint Programming to facilitate interactive decision support. We study this hybrid framework through the lens of meeting scheduling, a time-consuming daily activity faced by a multitude of information workers. We conduct three studies to evaluate the novel framework, including a diary study (n=64) to characterize contextual scheduling preferences, a quantitative evaluation of the system's performance, and a user study (n=10) with a prototype system. Our work highlights the potential for a hybrid LLM and optimization approach for iterative preference elicitation and design considerations for building systems that support human-system collaborative decision-making processes.

description: Massive black hole binaries (MBHBs) with masses of ~ 10^4 to ~ 10^10 of solar masses are one of the main targets for currently operating and forthcoming space-borne gravitational wave observatories. In this paper, we explore the effect of the stellar host rotation on the bound binary hardening efficiency, driven by three-body stellar interactions. As seen in previous studies, we find that the centre of mass (CoM) of a prograde MBHB embedded in a rotating environment starts moving on a nearly circular orbit about the centre of the system shortly after the MBHB binding. In our runs, the oscillation radius is approximately 0.25 ( approximately 0.1) times the binary influence radius for equal mass MBHBs (MBHBs with mass ratio 1:4). Conversely, retrograde binaries remain anchored about the centre of the host. The binary shrinking rate is twice as fast when the binary CoM exhibits a net orbital motion, owing to a more efficient loss cone repopulation even in our spherical stellar systems. We develop a model that captures the CoM oscillations of prograde binaries; we argue that the CoM angular momentum gain per time unit scales with the internal binary angular momentum, so that most of the displacement is induced by stellar interactions occurring around the time of MBHB binding, while the subsequent angular momentum enhancement gets eventually quashed by the effect of dynamical friction. The effect of the background rotation on the MBHB evolution may be relevant for LISA sources, that are expected to form in significantly rotating stellar systems.

description: Optical coherence tomography (OCT) is a non-invasive imaging technique with extensive clinical applications in ophthalmology. OCT enables the visualization of the retinal layers, playing a vital role in the early detection and monitoring of retinal diseases. OCT uses the principle of light wave interference to create detailed images of the retinal microstructures, making it a valuable tool for diagnosing ocular conditions. This work presents an open-access OCT dataset (OCTDL) comprising over 2000 OCT images labeled according to disease group and retinal pathology. The dataset consists of OCT records of patients with Age-related Macular Degeneration (AMD), Diabetic Macular Edema (DME), Epiretinal Membrane (ERM), Retinal Artery Occlusion (RAO), Retinal Vein Occlusion (RVO), and Vitreomacular Interface Disease (VID). The images were acquired with an Optovue Avanti RTVue XR using raster scanning protocols with dynamic scan length and image resolution. Each retinal b-scan was acquired by centering on the fovea and interpreted and cataloged by an experienced retinal specialist. In this work, we applied Deep Learning classification techniques to this new open-access dataset.

description: It is known that evaluating a certain approximation to the Jones polynomial for the plat closure of a braid is a BQP-complete problem. That is, this problem exactly captures the power of the quantum circuit model. The one clean qubit model is a model of quantum computation in which all but one qubit starts in the maximally mixed state. One clean qubit computers are believed to be strictly weaker than standard quantum computers, but still capable of solving some classically intractable problems. Here we show that evaluating a certain approximation to the Jones polynomial at a fifth root of unity for the trace closure of a braid is a complete problem for the one clean qubit complexity class. That is, a one clean qubit computer can approximate these Jones polynomials in time polynomial in both the number of strands and number of crossings, and the problem of simulating a one clean qubit computer is reducible to approximating the Jones polynomial of the trace closure of a braid.

Resonant self-force effects in extreme-mass-ratio binaries: A scalar model

description: Extreme-mass ratio inspirals (EMRIs), compact binaries with small mass ratios $ε\ll 1$, will be important sources for low-frequency gravitational wave detectors. Almost all EMRIs will evolve through important transient orbital $rθ$ resonances, which will enhance or diminish their gravitational wave flux, thereby affecting the phase evolution of the waveforms at $O(ε^{1/2})$ relative to leading order. While modeling the local gravitational self-force (GSF) during resonances is essential for generating accurate EMRI waveforms, so far the full GSF has not been calculated for an $rθ$-resonant orbit owing to computational demands of the problem. As a first step we employ a simpler model, calculating the scalar self-force (SSF) along $rθ$-resonant geodesics in Kerr spacetime. We demonstrate two ways of calculating the $rθ$-resonant SSF (and likely GSF), with one method leaving the radial and polar motions initially independent as if the geodesic is nonresonant. We illustrate results by calculating the SSF along geodesics defined by three $rθ$-resonant ratios (1:3, 1:2, 2:3). We show how the SSF and averaged evolution of the orbital constants vary with the initial phase at which an EMRI enters resonance. We then use our SSF data to test a previously proposed integrability conjecture, which argues that conservative effects vanish at adiabatic order during resonances. We find prominent contributions from the conservative SSF to the secular evolution of the Carter constant, $\langle \dot{\mathcal{Q}}\rangle$, but these nonvanishing contributions are on the order of, or less than, the estimated uncertainties of our self-force results. The uncertainties come from residual, incomplete removal of the singular field in the regularization process. Higher order regularization parameters, once available, will allow definitive tests of the integrability conjecture.

description: This paper presents a contact-implicit model predictive control (MPC) framework for the real-time discovery of multi-contact motions, without predefined contact mode sequences or foothold positions. This approach utilizes the contact-implicit differential dynamic programming (DDP) framework, merging the hard contact model with a linear complementarity constraint. We propose the analytical gradient of the contact impulse based on relaxed complementarity constraints to further the exploration of a variety of contact modes. By leveraging a hard contact model-based simulation and computation of search direction through a smooth gradient, our methodology identifies dynamically feasible state trajectories, control inputs, and contact forces while simultaneously unveiling new contact mode sequences. However, the broadened scope of contact modes does not always ensure real-world applicability. Recognizing this, we implemented differentiable cost terms to guide foot trajectories and make gait patterns. Furthermore, to address the challenge of unstable initial roll-outs in an MPC setting, we employ the multiple shooting variant of DDP. The efficacy of the proposed framework is validated through simulations and real-world demonstrations using a 45 kg HOUND quadruped robot, performing various tasks in simulation and showcasing actual experiments involving a forward trot and a front-leg rearing motion.

description: We address the problem of decoding video file fragments when the necessary encoding parameters are missing. With this objective, we propose a method that automatically generates H.264 video headers containing these parameters and extracts coded pictures in the partially available compressed video data. To accomplish this, we examined a very large corpus of videos to learn patterns of encoding settings commonly used by encoders and created a parameter dictionary. Further, to facilitate a more efficient search our method identifies characteristics of a coded bitstream to discriminate the entropy coding mode. It also utilizes the application logs created by the decoder to identify correct parameter values. Evaluation of the effectiveness of the proposed method on more than 55K videos with diverse provenance shows that it can generate valid headers on average in 11.3 decoding trials per video. This result represents an improvement by more than a factor of 10 over the conventional approach of video header stitching to recover video file fragments.
Robust Nonlinear Output Regulation by Identification Tools

Subjects: ING-INF/04 Automatica

description: The present thesis focuses on the problem of robust output regulation for minimum phase nonlinear systems by means of identification techniques. Given a controlled plant and an exosystem (an autonomous system that generates eventual references or disturbances), the control goal is to design a proper regulator able to process the only measure available, i.e the error/output variable, in order to make it asymptotically vanishing. In this context, such a regulator can be designed following the well known “internal model principle” that states how it is possible to achieve the regulation objective by embedding a replica of the exosystem model in the controller structure. The main problem shows up when the exosystem model is affected by parametric or structural uncertainties, in this case, it is not possible to reproduce the exact behavior of the exogenous system in the regulator and then, it is not possible to achieve the control goal. In this work, the idea is to find a solution to the problem trying to develop a general framework in which coexist both a standard regulator and an estimator able to guarantee (when possible) the best estimate of all uncertainties present in the exosystem in order to give “robustness” to the overall control loop.

description: This paper addresses the workspace analysis of two 3-DOF translational parallel mechanisms designed for machining applications. The two machines features three fixed linear joints. The joint axes of the first machine are orthogonal whereas these of the second are parallel. In both cases, the mobile platform moves in the Cartesian $x-y-z$ space with fixed orientation. The workspace analysis is conducted on the basis of prescribed kinetostatic performances. Interval analysis based methods are used to compute the dextrous workspace and the largest cube enclosed in this workspace.

description: We present a new lens model for the $z=0.396$ galaxy cluster MACS J0416.1$-$2403 based on a previously known set of 77 spectroscopically confirmed, multiply imaged galaxies plus an additional set of 42 candidate multiply imaged galaxies from past HST and new JWST data. The new galaxies lack spectroscopic redshifts but have geometric and/or photometric redshift estimates that are presented here. The new model predicts magnifications and time delays for all multiple images. The full set of constraints totals 343, constituting the largest sample of multiple images lensed by a single cluster to date. Caustic-crossing galaxies lensed by this cluster are especially interesting. Some of these galaxies show transient events, most of which are interpreted as micro-lensing of stars at cosmological distances. These caustic-crossing arcs are expected to show similar events in future, deeper JWST observations. We provide time delay and magnification models for all these arcs. The time delays and the magnifications for different arcs are generally anti-correlated, as expected from $N$-body simulations.
 In the major sub-halos of the cluster, the dark-matter mass from our lens model correlates well with the observed number of globular clusters. This confirms earlier results, derived at lower redshifts, which suggest that globular clusters can be used as powerful mass proxies for the halo masses when lensing constraints are scarce or not available.

description: In this paper, we consider Poincaré inequalities for non euclidean metrics on $\mathbb{R}^d$. These inequalities enable us to derive precise dimension free concentration inequalities for product measures. This technique is appropriate for a large scope of concentration rate: between exponential and gaussian and beyond. We give different equivalent functional forms of these Poincaré type inequalities in terms of transportation-cost inequalities and infimum convolution inequalities. Workable sufficient conditions are given and a comparison is made with generalized Beckner-Latala-Oleszkiewicz inequalities.

description: This Thesis aims at building and discussing mathematical models applications focused on Energy problems, both on the thermal and electrical side.

The objective is to show how mathematical programming techniques developed within Operational Research can give useful answers in the Energy Sector, how they can provide tools to support decision making processes of Companies operating in the Energy production and distribution and how they can be successfully used to make simulations and sensitivity analyses to better understand the state of the art and convenience of a particular technology by comparing it with the available alternatives.

The first part discusses the fundamental mathematical background followed by a comprehensive literature review about mathematical modelling in the Energy Sector. 

The second part presents mathematical models for the District Heating strategic network design and incremental network design. The objective is the selection of an optimal set of new users to be connected to an existing thermal network, maximizing revenues, minimizing infrastructure and operational costs  and taking into account the main technical requirements of the real world application. Results on real and randomly generated benchmark networks are discussed with particular attention to instances characterized by big networks dimensions.

The third part is devoted to the development of linear programming models for optimal battery operation in off-grid solar power schemes, with consideration of battery degradation.
The key contribution of this work is the inclusion of battery degradation costs in the optimisation models. As available data on relating degradation costs to the nature of charge/discharge cycles are limited, we concentrate on investigating the sensitivity of operational patterns to the degradation cost structure. The objective is to investigate the combination of battery costs and performance at which such systems become economic. We also investigate how the system design should change when battery degradation is taken into account.

description: In this paper, we consider the problem of finding a regression in a version control system (VCS), such as git. The set of versions is modelled by a Directed Acyclic Graph (DAG) where vertices represent versions of the software, and arcs are the changes between different versions. We assume that somewhere in the DAG, a bug was introduced, which persists in all of its subsequent versions. It is possible to query a vertex to check whether the corresponding version carries the bug. Given a DAG and a bugged vertex, the Regression Search Problem consists in finding the first vertex containing the bug in a minimum number of queries in the worst-case scenario. This problem is known to be NP-complete. We study the algorithm used in git to address this problem, known as git bisect. We prove that in a general setting, git bisect can use an exponentially larger number of queries than an optimal algorithm. We also consider the restriction where all vertices have indegree at most 2 (i.e. where merges are made between at most two branches at a time in the VCS), and prove that in this case, git bisect is a $\frac{1}{\log_2(3/2)}$-approximation algorithm, and that this bound is tight. We also provide a better approximation algorithm for this case. Finally, we give an alternative proof of the NP-completeness of the Regression Search Problem, via a variation with bounded indegree.

description: The superconformal index of $\frac12$-BPS states of $N=4$ U(N) super Yang-Mills theory has a known infinite $q$-series expression with successive terms suppressed by $q^N$. We derive a holographic bulk interpretation of this series by evaluating the corresponding functional integral in the dual $AdS_5 \times S^5$. The integral localizes to a product of small fluctuations of the vacuum and of the collective modes of an arbitrary number of giant-gravitons wrapping an $S^3$ of maximal size inside the $S^5$. The quantum mechanics of the small fluctuations of one maximal giant is described by a supersymmetric version of the Landau problem. The quadratic fluctuation determinant reduces to a sum over the supersymmetric ground states, and precisely reproduces the first non-trivial term in the infinite series. Further, we show that the terms corresponding to multiple giants are obtained precisely by the matrix versions of the above super-quantum-mechanics.
The Tantra-śuddha of Bhaṭṭāraka-Śrī-Vedottama : a translation and commentary
Creators: name: Fern, David John
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a translation of and commentary on the Tantra-iuddha (Purity of the System), a 14th century (circa) Sanskrit philosophical monograph defending the religious validity of the Pancaratra school. The work is attributed to a Sri Bhattaraka-sri-vedottama. Set in the framework of a debate between two Mimamsaka disputants the text follows the "objection-response" (purva-paksa - uttara-paksa) format so characteristic of the genre. I have divided the work into three more or less cohesive sections. In the first the author is faced with the problem of justifying the validity of his school and its smrti in the absence of confirmation by a sruti. He does so by hypothesizing a supporting sruti which existed in the past but has since been lost. In Section 2 the opponent plays the devil's advocate and suggests that the author: 1. Claim universal validity for all smrtis, (independent of sruti support), 2. reject the traditional requirement that smrtis be free from any taint of an ulterior motive, and 3. claim the status for the smrti of being an equally valid alternative to sruti in instances where the two appear to conflict. Fully cognizant that to accept any of these would be to undermine his position the author rejects all three proposals. In the third section the author clarifies the distinctions between his own school and four Saivite ones. He then responds to a number of objections and citations that declare the Pancaratra system to be non-Vedic, both in its beliefs and in its ritual practices. This he does by reinterpreting the intentions of alleged opponents such as Sankara and Rumania or by simply declaring deprecatory passages as inaccurate. The text draws heavily upon an earlier work by Yamuna, the Agama-pramanya, which also sought to defend the Pancaratrikas. Arguments and conclusions correlate highly throughout, with one significant difference. Whereas Yamuna speaks from the perspective of Vislstadvaita Vedanta, Bhattaraka Vedottama infuses the Pancaratra school with a much more monist tinge. This is perhaps the sole reason for studying the text; it reminds us that religious schools are rarely stagnant. Considerable variation occurred within movements bearing the same name and we would be foolish to cling to our generalizations too seriously.

description: Lo studio delle biblioteche gesuitiche è stato oggetto di ricerca per verificare la formazione delle classi dirigenti. Purtroppo all’atto delle loro espulsioni nella seconda metà del  XVIII secolo gran parte del loro patrimonio librario è andato perduto. Lo studio della biblioteca storica del Liceo Classico M. Morelli di Vibo Valentia, compiuta attraverso gli ex libris e i documenti contenuti nell’Archivio di Stato di Catanzaro, consente di verificare come l’intento giurisdizionalista di porre sotto il controllo statale la formazione scolastica abbia come esito il tentativo, fallito, di creare una biblioteca pubblica con i libri sequestrati ai disciolti collegi e gestiti dalla Cassa Sacra.

description: This paper represents the first systematization of an ethnography based on Molise in the framework of a wider interest in regional/national/global processes of heritagization and monitoring put in place in the last two decades, above all, but not exclusively by the UNESCO framework, Council of Europe and other global contexts of conservation/valorisation policies. The Region Molise, being small and relatively secluded, is particularly fit for advancing some methodological and theoretical issues. The research is focused on bio-cultural heritage and transhumance/traditional pastoralism revitalization as a cultural/tourist path, especially in the inner regions of Northern Italy, but also in the South. Moreover, transhumance has recently been reconsidered as a new form of sustainable breeding activity and a very embedded practice in the local.

Questo saggio è una prima sintesi di un’etnografia svolta in Molise nel quadro di un più ampio interesse per i processi di patrimonializzazione a livello regionale/nazionale/globale nell’ultimo ventennio, essenzialmente nel quadro, seppur non esclusivo, delle politiche UNESCO, del Consiglio di Europa e di altre cornici globali di salvaguardia e valorizzazione dei beni immateriali e materiali. Il Molise risulta per le sue dimensioni e per la relativa appartatezza, adatto ad osservare alcune dinamiche e avanzare alcune riflessioni. La ricerca è incentrata sul patrimonio bio-culturale e in particolar modo sulla pratica della transumanza e del pascolo vagante rivitalizzati recentemente nel quadro di percorsi e cammini turistici, soprattutto in alcune aree interne e montane dell’Italia Settentrionale, ma anche più recentemente in alcune zone del centro-meridione. Ancor più recentemente queste forme di pastorizia tradizionale sono state riconcettualizzate come espressione di un sistema di allevamento sostenibile e di pratiche rurali fortemente radicate nella località e come risorsa per lo sviluppo delle aree maggiormente periferiche e interne del Paese.

Le relazioni politiche tra Norcia e il governo pontificio nel Quattrocento / Political relations between Norcia and the Papacy in the fifteenth century
Creators: name: Lattanzio, Federico
Publisher: name: eum
Year: 2019

description: Gli obiettivi del saggio partono dal tratteggiamento del quadro territoriale ed economico della Norcia del secolo XV e dalla ricostruzione della sua vita civica: istituzioni, uffici e assemblee. Si passa poi all’analisi della società locale, con l’individuazione delle famiglie eminenti, delle caratteristiche degli altri gruppi sociali, dell’assetto e della composizione del ceto dirigente. Infine si giunge all’esame dei rapporti politici con il governo papale, soprattutto dei metodi di intervento attuati dalla S. Sede per controllare l’area in questione. Metodologicamente il saggio si fonda sulla connessione tra lo studio delle società locali, soprattutto dei gruppi dirigenti cittadini, e lo studio delle relazioni tra esse e il potere centrale. Tra i risultati principali, in questo caso, emergono alcune rilevanti specificità del contesto di Norcia, che evidenziano la diversità degli atteggiamenti con cui il governo papale si relazionava con i diversi soggetti politici del proprio Stato.

The objectives of the essay start from the tracing of the territorial and economic framework of Norcia in the XVth century, and from the reconstruction of its civic life: institutions, offices and assemblies. Then the essay moves on to the analysis of the local society, to the identification of the eminent families, of the characteristics of the other social groups, of the structure and composition of the ruling class. Finally are examinated the political relations with the papal government, especially the methods of intervention used by the Holy See to control that area. Methodologically the essay is based on the connection between the study of local societies, especially about the cities' leading groups, and the study of the relations between them and the central power. Among the main results, in this case, emerge some significant specificities of the Norcia context, which highlight the diversity of methods used by the papal government to relate to the different political subjects of its State.

description: We aim to understand the formation of cloud condensation nuclei in oxygen-rich substellar atmospheres by calculating fundamental properties of the energetically most favorable vanadium oxide molecules and clusters. A hierarchical optimization approach is applied in order to find the most favorable structures for clusters of (VO)$_{N}$ and (VO$_2$)$_{N}$ for N=1-10, and (V$_2$O$_5$)$_{N}$ for N=1-4 and to calculate their thermodynamical potentials. The candidate geometries are initially optimized applying classical interatomic potentials and then refined at the B3LYP/cc-pVTZ level of theory to obtain accurate zero-point energies and thermochemical quantities. We present previously unreported vanadium oxide cluster structures as lowest-energy isomers. We report revised cluster energies and their thermochemical properties. Chemical equilibrium calculations are used to asses the impact of the updated and newly derived thermodynamic potentials on the gas-phase abundances of vanadium-bearing species. In chemical equilibrium, larger clusters from different stoichiometric families are found to be the most abundant vanadium-bearing species for temperatures below ~1000 K, while molecular VO is the most abundant between ~1000 K and ~2000 K. We determine the nucleation rates of each stoichiometric family for a given (T$_{gas}$, p$_{gas}$) profile of a brown dwarf using classical and non-classical nucleation theory. Small differences in the revised Gibbs free energies of the clusters have a large impact on the abundances of vanadium bearing species in chemical equilibrium at temperatures below ~1000 K, which subsequently has an impact on the nucleation rates of each stoichiometric family. We find that with the revised and more accurate cluster data non-classical nucleation rates are up to 15 orders of magnitude higher than classical nucleation rates.

description: Effects due to magneto-optical interactions are responsible for most of the phenomena discovered in optoelectronics and spintronics. Magneto-optical interactions can generate elementary excitations of the order of light-magnetic matter, which can flow under certain conditions. Here, we observe the intensities of magneto-optical interactions in hexagonal arrays of magnetic nanowires using experimental measurements and simulations. Nanowires of three materials (cobalt-Co, iron-Fe, and nickel-Ni) were electrodeposited on alumina membranes by the AC electrodeposition method. Our results reveal that the magneto-optical behavior can produce, under certain conditions, a kind of avalanche of magneto-optical interactions, which is dynamic. Such an observation shows the possibility of generating a magneto-optical current (spin-opto current).

Industrial Algoma and the myth of wilderness : Algoma landscapes and the emergence of the Group of Seven, 1918-1920
Creators: name: Fletcher, Allan John
Publisher: name: University of British Columbia
Year: 2010

description: In the summer of 1988, casting around for a thesis topic, I chanced on some photographs which stunned me. They were pictures of various sites in the Algoma territory, a region which up to that time I, like many Canadians, knew only from idyllic paintings by J. E. H. MacDonald and other members of the Group of Seven. The discrepancy between the two sets of images was startling. What the camera revealed: railyards, dockyards, cities and towns, dammed rivers, cavernous mines, mountains of slag, razed forests, huge smelters and gigantic milling operations was in striking contrast to the untouched northern wilderness depicted in works like The Solemn Land. I felt that art historians had helped foster the illusion that Algoma was (and is) as pure and unsullied as the Group depicted it. My thesis, then, is at its most basic level an attempt to counteract that false impression and inject some balance into the art historical record. It looks at the mythical structures of the north and the wilderness and shifts in their political, social and economic utility in the years just after the Great War and tries to locate Algoma paintings made between 1918 and 1920 within this larger context. The phenomenon of Tom Thomson, the archetype of the "bush artist" is considered as are issues of private and institutional patronage. Actual and potential audiences for Algoma art are examined, and a number of texts, promotional and critical are discussed. In the final chapter, four paintings, three by J. E. H. MacDonald and one by Frank H. Johnston are investigated and related to what I see as the primary task of much artistic production at this time—to harmonize Canadian culture with country's accelerating transition to a branch-plant economy.

description: We investigate the numerical performance of a Discontinuous Galerkin (DG) hydrodynamics implementation when applied to the problem of driven, isothermal supersonic turbulence. While the high-order element-based spectral approach of DG is known to efficiently produce accurate results for smooth problems (exponential convergence with expansion order), physical discontinuities in solutions, like shocks, prove challenging and may significantly diminish DG's applicability to practical astrophysical applications. We consider whether DG is able to retain its accuracy and stability for highly supersonic turbulence, characterized by a network of shocks. We find that our new implementation, which regularizes shocks at sub-cell resolution with artificial viscosity, still performs well compared to standard second-order schemes for moderately high Mach number turbulence, provided we also employ an additional projection of the primitive variables onto the polynomial basis to regularize the extrapolated values at cell interfaces. However, the accuracy advantage of DG diminishes significantly in the highly supersonic regime. Nevertheless, in turbulence simulations with a wide dynamic range that start with supersonic Mach numbers and can resolve the sonic point, the low numerical dissipation of DG schemes still proves advantageous in the subsonic regime. Our results thus support the practical applicability of DG schemes for demanding astrophysical problems that involve strong shocks and turbulence, such as star formation in the interstellar medium. We also discuss the substantial computational cost of DG when going to high order, which needs to be weighted against the resulting accuracy gain. For problems containing shocks, this favours the use of comparatively low DG order.

description: Parahydrogen-Induced Polarization (PHIP) is a potent technique for generating target molecules with high nuclear spin polarization. The PHIP process involves a chemical reaction between parahydrogen and a target molecule, followed by the transformation of nuclear singlet spin order into magnetization of a designated nucleus through magnetic field manipulations. Although the singlet-to-magnetization polarization transfer process works effectively at moderate concentrations, it is observed to become much less efficient at high molar polarization, defined as the product of polarization and concentration. This strong dependence on the molar polarization is attributed to interference from the field produced by the sample's magnetization during polarization transfer, which leads to complex dynamics and can severely impact the scalability of the technique. We address this challenge with a pulse sequence that negates the influence of the distant dipolar field, while simultaneously achieving singlet-to-magnetization polarization transfer to the desired target spins, free from restrictions on the molar polarization.

description: The (4,4) null superstring equations of motions and constraints on de Sitter space are given by using the harmonic superspace. These are solved explicitly by performing a perturbative expansion of the (4,4) superstring coordinates in powers of c2, the world-sheet speed of light. The analytic expressions of the zeroth and first order solutions are determined. On the other hand, we study the quantization of the (4,4)null superstring in de Sitter space and we describe its superalgebra.
