description: Increasing attention has been recently devoted to protein-based nanobiosensors. The main reason is the huge number of possible technological applications, going from drug detection to cancer early diagnosis. Their operating model is based on the protein activation and the corresponding conformational change, due to the capture of an external molecule, the so-called ligand. Recent measurements, performed with different techniques on human 17-40 olfactory receptor, evidenced a very narrow window of response in respect of the odour concentration. This is a crucial point for understanding whether the use of this olfactory receptor as sensitive part of a nanobiosensor is a good choice. In this paper we investigate the topological and electrical properties of the human olfactory receptor 17-40 with the objective of providing a microscopic interpretation of available experiments. To this purpose, we model the protein by means of a graph able to capture the mean features of the 3D backbone structure. The graph is then associated with an equivalent impedance network, able to evaluate the impedance spectra of the olfactory receptor, in its native and activated state. We assume a topological origin of the different protein electrical responses to different ligand concentrations: In this perspective all the experimental data are collected and interpreted satisfactorily within a unified scheme, also useful for application to other proteins.

description: Feedbacks that can destabilize the climates of synchronously-rotating rocky planets may arise on planets with strong day-night surface temperature contrasts. Earth-like habitable-zone (HZ) planets maintain stable surface liquid water over geological time. This requires equilibrium between the temperature-dependent rate of greenhouse-gas consumption by weathering,and greenhouse-gas resupply by other processes. Detected small-radius exoplanets, and anticipated M-dwarf HZ rocky planets, are expected to be tidally locked. We investigate two feedbacks that can destabilize climate on tidally-locked planets. (1) If small changes in pressure alter the temperature distribution across a planet's surface such that the weathering rate increases when the pressure decreases, a positive feedback occurs involving increasing weathering rate near the substellar point, decreasing pressure, and increasing substellar surface temperature. (2) When decreases in pressure increase the surface area above the melting point (through reduced advective cooling of the substellar point), and the corresponding increase in volume of liquid causes net dissolution of the atmosphere, a further decrease in pressure occurs. We use an idealized energy balance model to map out the conditions under which these instabilities may occur. The weathering runaway can shrink the habitable zone, and cause geologically rapid 10^3-fold pressure shifts within the HZ. Mars may have undergone a weathering runaway in the past. Substellar dissolution is usually a negative feedback or weak positive feedback on changes in pressure. Both instabilities are suppressed if the atmosphere has a high radiative efficiency. Our results are most relevant for atmospheres that are thin and have low greenhouse-gas radiative efficiency. These results identify a new pathway by which HZ planets can undergo rapid climate shifts and become uninhabitable.

title: Collaborative Decision Making as a Tool for Improving Decision-Making Processes in the Multicultural Environment of a Multinational Joint Venture

description: Abstract Collaborative Decision Making as a Tool for Improving Decision-Making Processes in the Multicultural Environment of a Multinational Joint Venture The importance of collaborative and collective behaviours, operations, and processes in human social interactions is clear and unquestionable. It has been evident at every stage of human development and lies at the roots of the very progress of mankind. Today, with distant cultures mingling and interacting with each other more than ever, the significance and impact of collaborative and cooperative behaviours and practices on successful business operations of international joint ventures (IJVs) is unquestionable. An important factor in the ever-changing landscape of business, is the exclusion of African organisations from most academic considerations (Zoogah et al., 2014) and that gap I strived to fill. I posit that changes in decision-making patterns, from a strict chain of command to more collaborative practices are necessary for successful navigation of national culture induced differences between stakeholders. This study shows that Nigerian and European employees—as nationally diverse decision-makers inhabiting very diverse perspectives— were unaware of the ambiguity experienced by other parties, despite being very willing to collaborate towards the company’s common goals and visions, at least at the beginning of the project. The inability to understand and adapt to each other’s perspectives gradually caused the development of mutual distrust or disrespect, as well as the misunderstanding of individual approaches, intentions, and attitudes. In addition, foreign partners often did not understand the fundamental mechanics of local institutions, which have a considerable impact on the performance of the IJV. The study was conducted over a period of approximately three years, using a mixed research methodology underpinned by strong pragmatism. I found that collaborative decision-making is indeed possible in a multinational IJV, despite the challenges faced in its achievement. Indeed, once established, such decision-making practices become an excellent tool for improving the quality of decisions. I also note that collaborative practices help multicultural organisations, particularly by harnessing differences between diverse national cultures, to create a unified corporate vision. A distinct organisational culture resulting from the merging of the diverse cultures of collaborating stakeholders can therefore emerge by building on differences rather than allowing them to be divisive. As the final conclusions of this research, I can posit that if IJVs with culturally diverse stakeholders follow the proposed approach, they can become more democratic, inclusive, and adaptive, attaining a competitive advantage through such emergent flexibility, resilience and collaboratively making good-quality decisions.
Unveiling the Secrets of Gamma Ray Bursts

description: Gamma Ray Bursts (GRBs) are unpredictable and brief flashes of gamma rays that occur about once a day in random locations in the sky. Since gamma rays do not penetrate the Earth's atmosphere, they are detected by satellites, which automatically trigger ground-based telescopes for follow-up observations at longer wavelengths. In this introduction to Gamma Ray Bursts we review how building a multi-wavelength picture of these events has revealed that they are the most energetic explosions since the Big Bang and are connected with stellar deaths in other galaxies. However, in spite of exceptional observational and theoretical progress in the last 15 years, recent observations raise many questions which challenge our understanding of these elusive phenomena. Gamma Ray Bursts therefore remain one of the hottest topics in modern astrophysics.

description: Integration of palynology and micropaleontology in an analysis of sediment cores and stratigraphic sections from the Gwaii Haanas Archipelago (southern Moresby Island) and adjacent Hecate Strait allows improved detailing of the sea-level curve for Haida Gwaii (Queen Charlotte Islands). Transgressive and regressive events are established through analysis of several types of microfossils inluding pollen, dinocysts, diatoms, foraminifera and thecamoebians. This research shows that the early Holocene marine transgression in this area was very rapid. Mean sea level reached a maximum elevation of approximately 14 metres above present levels at about 9,000 years ago and relative sea-levels remained between 12.5 and 14 metres elevation above present levels until about 5,500 years ago. These results are highly significant in the search for and meaning of early archaeological sites in this area.

description: This project examines the history of disabled students and disability rights activism at the University of Chicago after the passage of Section 504 but before the passage of the Americans with Disabilities Act (ADA) and contextualizes the protest within moments of activism at other universities like Northwestern University and the University of Illinois at Chicago, and within the broader disability rights movement. Using the lens of the 1983 protest staged by social work student Jeff Ellis and the Ad Hoc Committee on Handicapped Access, I argue that the access regulations outlined by Section 504 of the Rehabilitation Act of 1973 were largely ignored by the University, demonstrating that access was mainly a concern of affected students and their allies, and that administrators thought of disability as an individual problem to resolve, rather than a facet of societal diversity. UChicago students used tactics like direct action, petitioning, and legal means to attempt to persuade administrators to install an adequate lift. The results of their efforts are uncertain. I argue that UChicago’s attitude toward access lagged behind that of public institutions such as UIC, but that it was on par with Northwestern’s, exposing greater reticence on the part of private universities to prioritize physical access. Private universities like UChicago and Northwestern have always been slower to act, revealing that private universities did not conceive of the “elite” and worthy student as disabled.

description: We present a comparison of archival Spitzer spectra of the strongly variable T Tauri EX Lupi, observed before and during its 2008 outburst. We analyze the mid-infrared emission from gas-phase molecules thought to originate in a circumstellar disk. In quiescence the emission shows a forest of H2O lines, highly excited OH lines, and the Q branches of the organics C2H2, HCN, and CO2, similar to the emission observed toward several T Tauri systems. The outburst emission shows instead remarkable changes: H2O and OH line fluxes increase, new OH, H2, and HI transitions are detected, and organics are no longer seen. We adopt a simple model of a single-temperature slab of gas in local thermal equilibrium, a common approach for molecular analyses of Spitzer spectra, and derive the excitation temperature, column density, and emitting area of H2O and OH. We show how model results strongly depend on the selection of emission lines fitted, and that spectrally-resolved observations are essential for a correct interpretation of the molecular emission from disks, particularly in the case of water. Using H2O lines that can be approximated as thermalized to a single temperature, our results are consistent with a column density decrease in outburst while the emitting area of warm gas increases. A rotation diagram analysis suggests that the OH emission can be explained with two temperature components, which remarkably increase in column density in outburst. The relative change of H2O and OH emission suggests a key role for UV radiation in the disk surface chemistry.

description: Let $E$ be a locally compact separable metric space and $m$ be a positive Radon measure on it. Given a nonnegative function $k$ defined on $E\times E$ off the diagonal whose anti-symmetric part is assumed to be less singular than the symmetric part, we construct an associated regular lower bounded semi-Dirichlet form $η$ on $L^2(E;m)$ producing a Hunt process $X^0$ on $E$ whose jump behaviours are governed by $k$. For an arbitrary open subset $D\subset E$, we also construct a Hunt process $X^{D,0}$ on $D$ in an analogous manner. When $D$ is relatively compact, we show that $X^{D,0}$ is censored in the sense that it admits no killing inside $D$ and killed only when the path approaches to the boundary. When $E$ is a $d$-dimensional Euclidean space and $m$ is the Lebesgue measure, a typical example of $X^0$ is the stable-like process that will be also identified with the solution of a martingale problem up to an $η$-polar set of starting points. Approachability to the boundary $\partial D$ in finite time of its censored process $X^{D,0}$ on a bounded open subset $D$ will be examined in terms of the polarity of $\partial D$ for the symmetric stable processes with indices that bound the variable exponent $α(x)$.

description: Recently Navier-Stokes (NS) equations have been derived from the duality between the black branes and a conformal fluid on the boundary of AdS_5. Nevertheless, the full correspondence has to be established between solutions of supergravity in AdS_5 and supersymmetric field theories on the boundary. That prompts the construction of NS equations for a supersymmetric fluid. In the framework of rigid susy, there are several possibilities and we propose one candidate. We deduce the equations of motion in two ways: both from the divergenless condition on the energy-momentum tensor and by a suitable parametrization of the auxiliary fields. We give the complete component expansion and a very preliminary analysis of the physics of this supersymmetric fluid.

description: Exotic quantum spin liquid (QSL) is formed with such hypothetic particles as fermionic spinons carrying spin 1/2 and no charge. Here we calculate its thermodynamic and relaxation properties. Our calculations unveil the fundamental properties of QSL, forming strongly correlated Fermi system located at a fermion condensation quantum phase transition. These are in a good agreement with experimental data and allow us to detect the behavior of QSL as that observed in heavy fermion metals. We predict that the thermal resistivity of QSL under the application of magnetic fields at fixed temperature demonstrates a very specific behavior. The key features of our findings are the presence of spin-charge separation and QSL formed with itinerant heavy spinons in herbertsmithite.

description: Queen Elizabeth II died on 8 September 2022. Her death, after a reign of over 70 years, set in motion a series of events, political and constitutional, religious and ceremonial, which both conformed to a long-established pattern while also introducing new elements. The death of the monarch, the proclamation of the successor, and the mourning and funeral rites are, as they always have been, vehicles for more than the bare protocol itself contains. Choices are made, even – and perhaps especially – when the desired impression is one of continuity; the very presentation of these events requires decisions to be taken and plans to be made which project a certain aura, and attempt to direct the ways in which they are received. This article places those rites in their liturgical and historical context, and asks what meaning can be discerned in the liturgical and other choices made.

description: The present chapter focuses on the forward link of broadband multibeam satellite systems, where the goal is to increase the spectral efficiency by the means of aggressive frequency reuse configurations. In this direction, the imperfect multibeam satellite antenna cannot maintain the interference in acceptable levels when co-channel beams are in close proximity. Nevertheless, the multiple feeds offer the necessary spatial degrees of freedom to perform joint signal processing, namely precoding, at the transmitter. This chapter discusses one of the challenges of the application of precoding over satellite, namely the optimization of a multi-antenna satellite transmitter under the constraint of framing multiple users in single transmission. The significance of this problem is related to the inherent satellite channel characteristics that prevent the alleviation of specific framing structures for the sake of signal processing. Therefore, the application of precoding techniques with minimal impact on the structure of existing satellite standards is of utmost importance. Herein, the so-called frame-based precoding problem is defined, modeled, and solved using a selection of promising in terms of performance and complexity methods.

description: The paper describes a relatively new terrestrial remote sensing technique for deformation monitoring: ground-based SAR interferometry (GBSAR). It provides an introductory overview of this technique, making a short review of the most relevant GBSAR studies published in the literature. Then the basics of GBSAR interferometry for deformation measurement are outlined. Deriving deformation estimates from the GBSAR images is often not a straightforward process: a brief description of the GBSAR data processing chain developed by the authors is provided. Finally, the paper concisely discusses the main advantages and limitations of the technique.

description: The striped cuprate La$_{2-x}$Ba$_x$CuO$_4$ ($x=\frac18)$ undergoes several transitions below the charge-ordering temperature $T_{co}$ = 54 K. From Nernst experiments, we find that, below $T_{co}$, there exists a large, anomalous Nernst signal $e_{N,even}(H,T)$ that is symmetric in field $H$, and remains finite as $H\to 0$. The time-reversal violating signal suggests that, below $T_{co}$, vortices of one sign are spontaneously created to relieve interlayer phase frustration.

description: Manipulation-free and autonomous recording of temperature states for extended periods of time is of increasing importance for food spoilage and battery safety assessment. An optical readout is preferred for low-tech visual inspection. Here we introduce a concept for time-temperature integrators based on colloidal crystals. We combine two unique features in this class of advanced materials: 1) The film-formation kinetics can be controlled by orders of magnitude based on mixtures of particles with distinct glass transition temperatures. 2) A gradual variation of the particle mixture along a linear gradient of the colloidal crystal enables local readout. Tailor-made latex particles of identical size but different glass transition temperatures provide a homogenous photonic stopband. The disappearance of this opalescence is directly related to the local particle ratio and the exposure to a time and temperature combination. Our sensing material can be adjusted to report extended intermediate and short excessive temperature events, which makes it specifically suitable for long-term tracing and threshold applications.

description: A vertex coloring of a (possibly infinite) poset P 1s called good iff it leaves no nontrivial maximal antichain in P monochromatic. What is the minimum number of colors for which P admits a good coloring? By extending the result for finite posets, it can be shown that if P is well-founded and contains an element with no maximal antichain above it, then P admits a good three-coloring. For products of chains we exploit properties of cofinal and coinitial sequences to obtain good two-colorings in certain cases, the covering chain and club coloring results. As well, we introduce the concept of half-maximal antichain for its potential applications and its own merit. While attempting to extend the positive results thus far obtained, we found examples that violated the conditions of those results. At this point we are unable to determine the number of colors required by such examples.

description: This Letter reports an anomaly of film porosity dependence on deposition rate during physical vapor deposition - the porosity increases as deposition rate decreases. Using glancing angle deposition of Cu on SiO2 substrate, the authors show that the Cu film consists of well separated nanorods when the deposition rate is 1 nm/second, and that the Cu films consists of a more uniform (or lower porosity) film when the deposition rate is 6 nm/second; all other deposition conditions remain the same. This anomaly is the result of interplay among substrate non-wetting, density of Cu nuclei on the substrate, and the minimum diameter of nanorods.

description: Horizontal proper motions were measured with local correlation tracking (LCT) techniques in active region NOAA 11158 on 2011 February 15 at a time when a major (X2.2) solar flare occurred. The measurements are based on continuum images and magnetograms of the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory. The observed shear flows along the polarity inversion line were rather weak (a few 100 m/s). The counter-streaming region shifted toward the north after the flare. A small circular area with flow speeds of up to 1.2 km/s appeared after the flare near a region of rapid penumbral decay. The LCT signal in this region was provided by small-scale photospheric brigthenings, which were associated with fast traveling moving magnetic features. Umbral strengthening and rapid penumbral decay was observed after the flare. Both phenomena were closely tied to kernels of white-light flare emission. The white-light flare only lasted for about 15 min and peaked 4 min earlier than the X-ray flux. In comparison to other major flares, the X2.2 flare in active region NOAA 11158 only produced diminutive photospheric signatures.

description: Forschungsberichterstattung ist mittlerweile Alltag auf allen Ebenen des Wissenschaftsbetriebs:Forschende erfüllen regelmäßig Berichtspflichten gegenüber externen Förderorganisationen und Geldgebern. Leitungen benötigen im Wettbewerb um Ausstattung und Köpfe eine Übersicht über die Vielzahl an Forschungsinformationen, um gute Entscheidungen treffen zu können. Die öffentliche Rechenschaftslegung über Forschung, insbesondere über die Finanzierung, hat ebenfalls an Bedeutung gewonnen. Gleichzeitig haben Hochschulen und Forschungseinrichtungen immer noch überraschend große Probleme bei der Bereitstellung fachbezogener Informationen. Die Ursachen sind in den Institutionen meist ähnlich – eine verteile Datenhaltung ohne Schnittstellen, Verwaltungssysteme, die Forschungskontexte nicht abbilden, sowie die begrenzte Nutzbarkeit vorhandener Systeme für die Durchführung differenzierter Auswertungen. Mehrfacherfassungen sind an der Tagesordnung. Institutionsübergreifend bestehen weitere Hindernisse für ein effizientes Informationsmanagement: Fach- und Förderdatenbanken werden isoliert betrieben, es fehlt an Schnittstellen und Austauschformaten und bei der Entwicklung von Systemen werden Standardisierungsmöglichkeiten zu wenig genutzt. Die Entwicklung finanzierbarer und funktionaler Forschungs-informationssysteme und vor allem der Austausch vorhandener Informationen gehört ebenso zur IT-Entwicklung für die Wissenschaft, wie Campusmanagement oder geeignete Personal-und Finanzsysteme. Es ist schwer vorstellbar, dass Prozesse, die auf manuelle Eingaben und jährliche Datenabfragen angewiesen sind, in den zahlreichen wissenschaftlichen Einrichtungen dieser Welt auf Dauer erfolgreich fortgeführt werden können. Ebenso wenig ist wahrscheinlich, dass die Berichtsanforderungen abnehmen. Das Positionspapier zeigt auf strategischer Ebene auf, welche konkreten Schritte zur Entwicklung eines nachhaltigen Informationsmanagements in der Forschungsberichterstattung gegangen werden müssen. Eine Verständigung auf gemeinsame Standards ist die Grundvoraussetzung dafür, dass der nicht unbeträchtliche Aufwand für den Betrieb der Systeme gesenkt werden kann und mobilen Forschenden ermöglicht wird, ihr Portfolio in verschiedene Anwendungen zu übertragen und auch in andere Forschungseinrichtungen mitzunehmen. Die Arbeitsgruppe hat darüber hinaus konkrete handlungspraktische Hinweise für Systemauswahl, Einführung und Betrieb, Projektmanagement und Gestaltung der Systeme erarbeitet. Diese richten sich an Institutionen, die selbst ein Forschungsinformationssystem einführen oder entwickeln wollen.
Orbital effects of Lorentz-violating Standard Model Extension gravitomagnetism around a static body: a sensitivity analysis

description: We analytically work out the long-term rates of change of the six osculating Keplerian orbital elements of a test particle acted upon by the Lorentz-violating gravitomagnetic acceleration due to a static body, as predicted by the Standard Model Extension (SME). We neither restrict to any specific spatial orientation for the symmetry-violating vector s nor make a priori simplifying assumptions concerning the orbital configuration of the perturbed test particle. Thus, our results are quite general, and can be applied for sensitivity analyses to a variety of specific astronomical and astrophysical scenarios. We find that, apart from the semimajor axis a, all the other orbital elements undergo non-vanishing secular variations. By comparing our results to the latest determinations of the supplementary advances of the perihelia of some planets of the solar system we preliminarily obtain s_x = (0.9 +/- 1.5) 10^-8, s_y = (-4 +/- 6) 10^-9, s_z = (0.3 +/- 1) 10^-9. Bounds from the terrestrial LAGEOS and LAGEOS II satellites are of the order of s\sim 10^-3-10^-4.

description: In dynamical models of cortical networks, the recurrent connectivity can amplify the input given to the network in two distinct ways. One is induced by the presence of near-critical eigenvalues in the connectivity matrix W, producing large but slow activity fluctuations along the corresponding eigenvectors (dynamical slowing). The other relies on W being nonnormal, which allows the network activity to make large but fast excursions along specific directions. Here we investigate the tradeoff between nonnormal amplification and dynamical slowing in the spontaneous activity of large random neuronal networks composed of excitatory and inhibitory neurons. We use a Schur decomposition of W to separate the two amplification mechanisms. Assuming linear stochastic dynamics, we derive an exact expression for the expected amount of purely nonnormal amplification. We find that amplification is very limited if dynamical slowing must be kept weak. We conclude that, to achieve strong transient amplification with little slowing, the connectivity must be structured. We show that unidirectional connections between neurons of the same type together with reciprocal connections between neurons of different types, allow for amplification already in the fast dynamical regime. Finally, our results also shed light on the differences between balanced networks in which inhibition exactly cancels excitation, and those where inhibition dominates.

description: We collect the 2LAC and MOJAVE quasi-simultaneous data to investigate the radio-gamma connection of blazars. The cross sample contains 166 sources. The statistic analysis based on this sample confirms positive correlations between these two bands, but the correlations become weaker as the gamma-ray energy increases. The statistic results between various parameters show negative correlations of gamma-ray photon spectral index with gamma-ray loudness for both FSRQs and BL Lacertae objects, positive correlations of gamma-ray variability index with the gamma-ray loudness for FSRQs, a negative correlation of the gamma-ray variability index with the gamma-ray photon spectral index for FSRQs, and negative correlations of gamma-ray photon spectral index with gamma-ray luminosity for FSRQs. These results suggest that the gamma-ray variability may be due to changes inside the gamma-ray emission region like the injected power, rather than changes in the photon density of the external radiation fields, and the variability amplitude tends to be larger as the gamma-rays are closer to the high energy peak of spectral energy distribution. No correlation of variability index found for BL Lacertae objects implies that variability behavior may differ below and above the peak energy.

Numerical Calculation of the Fidelity for the Kondo and the Friedel-Anderson Impurities
Creators: name: Bergmann, Gerd

Publisher: name: arXiv
Year: 2011
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The fidelities of the Kondo and the Friedel-Anderson (FA) impurities are calculated numerically. The ground states of both systems are calculated with the FAIR (Friedel artificially inserted resonance) theory. The ground state in the interacting systems is compared with a nullstate in which the interaction is zero. The different multi-electron states are expressed in terms of Wilson states. The use of N Wilson states simulates the use of a large effective number N_{eff} of states. A plot of ln(F) versus N\proptoln(N_{eff}) reveals whether one has an Anderson orthogonality catastrophe at zero energy. The results are at first glance surprising. The ln(F)-ln(N_{eff}) plot for the Kondo impurity diverges for large N_{eff}. On the other hand, the corresponding plot for the symmetric FA impurity saturates for large N_{eff} when the level spacing at the Fermi level is of the order of the singlet-triplet excitation energy. The behavior of the fidelity allows one to determine the phase shift of the electron states in this regime. PACS: 75.20.Hr, 71.23.An, 71.27.+a, 05.30.-d
Sparseness of t-structures and negative Calabi-Yau dimension in triangulated categories generated by a spherical object

description: Let k be an algebraically closed field and let T be the k-linear algebraic triangulated category generated by a w-spherical object for an integer w. For certain values of w this category is classical. For instance, if w = 0 then it is the compact derived category of the dual numbers over k. As main results of the paper we show that for w \leq 0, the category T has no non-trivial t-structures, but does have one family of non-trivial co-t-structures, whereas for w \geq 1 the opposite statement holds. Moreover, without any claim to originality, we observe that for w \leq -1, the category T is a candidate to have negative Calabi-Yau dimension since Σ^w is the unique power of the suspension functor which is a Serre functor.

description: Version 2.0 of CRPropa is public software to model the extra-galactic propagation of ultra-high energy nuclei of atomic number Z<26 through structured magnetic fields and ambient photon backgrounds taking into account all relevant particle interactions. CRPropa covers the energy range 6*10^16 < E/eV < A*10^22 where A is the nuclear mass number. CRPropa can also be used to track secondary γ-rays and neutrinos which allows the study of their link with the charged primary nuclei -- the so called multi-messenger connection. After a general introduction we present several sample applications of current interest concerning the physics of extragalactic ultra-high energy radiation.

description: We report a systematic study of the hyperfine interaction between the electron spin of a single nitrogen-vacancy (NV) defect in diamond and nearby $^{13}$C nuclear spins, by using pulsed electron spin resonance spectroscopy. We isolate a set of discrete values of the hyperfine coupling strength ranging from 14 MHz to 400 kHz and corresponding to $^{13}$C nuclear spins placed at different lattice sites of the diamond matrix. For each lattice site, the hyperfine interaction is further investigated through nuclear spin polarization measurements and by studying the magnetic field dependence of the hyperfine splitting. This work provides informations that are relevant for the development of nuclear-spin based quantum register in diamond.
