description: Large scale excavations of Neolithic settlements and cemeteries along the Swedish east coast and on the islands of Gotland and Öland in the Baltic Sea during the last 30 years have produced a large amount of new information concerning the Funnel Beaker Culture, the Pitted Ware Culture and the Battle Axe Culture. Excavations of large areas in a number of sites have given us a much deeper understanding of how these societies were organized, how people made their living and how they buried their dead. Large scale studies of palaeoecological remains, lipids in ceramics and isotopes in animal and human bones have given us new information concerning differences in diet and economy, and studies of genetic material have produced new essential knowledge of ethnic and cultural affiliations. The excavation at Tråsättra covered the whole area of a permanent hunter-gatherer settlement that can be related to the late Pitted Ware Culture, ca. 2600– 2400calBC. This gave us the opportunity to study the organization of the settlement, economy and diet, craftsmanship and ritual activities in detail. Also, finds of a large number of anthropomorphic and zoomorphic clay figurines, a cult building with ritual deposits and a small cemetery made a unique analysis of religious and ideological aspects of the hunter-gatherers in the archipelago of the eastern middle part of Sweden during the late Middle Neolithic B possible.

description: This review summarizes all known results (up to this date) about methods of integration of the classical Lotka-Volterra systems with diffusion and presents a wide range of exact solutions, which are the most important from applicability point of view. It is the first attempt in this direction. Because the diffusive Lotka-Volterra systems are used for mathematical modeling enormous variety of processes in ecology, biology, medicine, physics and chemistry, the review should be interesting not only for specialists from Applied Mathematics but also those from other branches of Science. The obtained exact solutions can also be used as test problems for estimating the accuracy of approximate analytical and numerical methods for solving relevant boundary value problems.
title: Familial politics and the Stuart court masque.
Creators: name: Haslem, Michelle.
Publisher: name: University of Liverpool Repository
Year: 2023

description: This thesis contends that the monarch-centred view of the masque, which has prevailed since the publication in the 1960s and 1970s of Stephen Orgel's seminal works on the genre, needs to be challenged in the light of recent scholarship on the cultural agency of other members of the royal family. In my introduction I argue that while the New Historicism has been crucial in elucidating the theatricalization of power in the early Stuart court, its insistence on the inevitability of the collusion between art and sovereign power needs to be questioned. The masque has long been seen as a monolithic and univocal celebration of monarchical power, despite the fact that it was promoted at court not by King James but by other members of the royal family. Adopting a loosely chronological approach, this thesis retells the story of the 'Jacobean' court masque by recovering the role played in the commissioning and performance of masques by James's wife, his children, and his male favourites. The chapters set out to hear voices other than that of the King, and discover that, while panegyric was part of each masque, it was rarely as unequivocal as traditional criticism has suggested. On the contrary, the annual masques were frequently appropriated to express the oppositional agendas of factions at court, and above all, of members of James's own family. I argue that Queen Anne set a precedent for the disruptive use of the masque which she exploited to present herself as independent from the King, and to emphasise her importance as the mother of the royal children. Prince Henry, and later Prince Charles, both used the masque to contest the pacifist policies of the King, while Buckingham's success as a favourite was linked to his skilful exploitation of the masques as an integral part of his self-fashioning. Above all by shifting the focus away from King James to consider the more active participation in the masque of other members of the royal family, this thesis offers a possibility of moving beyond the current impasse of the subversion / containment debate to a more nuanced reading of the culture of the early Stuart court which recognises the delicate process of negotiation and accommodation in which the masquers and their audiences were engaged.

description: Herein we describe the development of cyclam-coated gold nanoparticles (cyclam-Au NPs) based sensitive colorimetric method for neomycin and gentamicin detection. The cyclam-Au NPs were characterised by UV–vis spectroscopy, fourier transform infrared spectroscopy, transmission electron microscopy techniques, dynamic light scattering and zeta potential measurements. The cyclam-Au NPs aggregated in presence of neomycin and gentamicin, which results a colour change from violet to blue. The characteristic absorption peak at 530 nm was bathochromic-shifted to a longer wavelength (660 nm). This confirms the aggregation of cyclam-Au NPs in the presence of neomycin as well as gentamicin via hydrogen bonding. The UV–vis absorption measurements employed to determine detection limit of neomycin and gentamicin. The detection limit is 1.87 × 10− 8 M and 2.35 × 10− 8 M for neomycin and gentamicin respectively.

Exact solutions of field equations and scalar equation are obtained. The characteristics of pure radiation are determined. An explicit form of the scalar field functions included in the Lagrangian of the considered quadratic theory of gravity is found. Trajectories of propagation of light rays in the considered gravitational-wave models are obtained.

description: A series of peptide-functionalised perylene imide molecules was studied to examine the effect of peptide chirality on the self-assembly of the perylene imides core into nanofibres. Peptide stereogenic positions, stereochemical configurations, amphiphilic substitution and perylene core modification were spectroscopically evaluated with respect to chiral assembly. For dipeptide molecules, stereocenters in peptide residue positions proximal to the perylene core (1–5 units) were found to impart helical chirality to the perylene core, while stereocenters in more distal residue positions did not exert a chiral influence. Diastereomers involving stereocenter inversions within the proximal residues consequently manifested spectroscopically as pseudo-enantiomers. Increased side-chain steric demand in the proximal positions gave similar chiral influence but exhibited diminished Cotton effect intensity with additional longer wavelength features attributed to interchain excimers. Replacing one of the two peptide substituents with an alkyl chain to create strongly amphiphilic perylene bisimides disrupted chiral self-assembly. On the other hand, amphiphilic structures achieved through the modification of the perylene imide core with a bisester moiety prompted strongly exciton-coupled, solvent-responsive self-assembly into long, chiral nanofilaments.

description: We extend and review our analysis of the nucleon \to Δ(1232) transition electroweak form factors from Ref. [1]. New fit of the Δ(1232) vector form factors to electron-proton scattering F_2 structure function is introduced as well, leading to results different from the popular parametrization of Ref. [2]. A clear model dependence of the extracted parameters emerges. Fit to neutrino scattering data is performed in all available isospin channels. The resulting axial mass is M_{AΔ}=0.85^{+0.09}_{-0.08} (GeV) and $C_5^A(0) = 1.10^{+0.15}_{-0.14}. The latter value is in accordance with Goldberger-Treiman relation as long as the deuteron effects are included.

description: Two new fluorescent chemosensors have been designed and synthesised through functionalisation of a common 7-aminocoumarin precursor. One sensor features a di(2-picoyl)amine metal ion-binding moiety that allows for selective detection of Zn2+ ions over other common cations in aqueous solution, with the sensor exhibiting a 5.4-fold increase in fluorescence upon Zn2+ binding (limit of detection = 26 nM). The second sensor incorporates an aminophenyl group designed to react with highly reactive oxygen species (hROS). This sensor reacts with ClO−  in preference to other ROS, exhibiting a 27-fold increase in fluorescence upon the addition of 150 equivalents of ClO−  (limit of detection = 2 μM).

description: We investigate methods to explore the CP nature of the $ t\bar{t}h $ coupling at the LHC, focusing on associated production of the Higgs with a $t \bar{t}$ pair. We first discuss the constraints implied by low-energy observables and by the Higgs-rate information from available LHC data, emphasizing that they cannot provide conclusive evidence on the nature of this coupling. We then investigate kinematic observables that could probe the $ t\bar{t}h $ coupling directly, in particular quantities that can be constructed out of just lab-frame kinematics. We define one such observable by exploiting the fact that $t \bar{t}$ spin correlations do also carry information about the CP-nature of the $ t\bar{t}h $ coupling. Finally, we introduce a CP-odd quantity and a related asymmetry, able to probe CP violation in the $ t\bar{t}h $ coupling and likewise constructed out of lab-frame momenta only.

description: We study the interplay between the Hofstadter butterfly, strong interactions and Zeeman field within the mean-field Bogoliubov-de Gennes theory in real space, and explore the ground states of the attractive single-band Hofstadter-Hubbard Hamiltonian on a square lattice, including the exotic possibility of imbalanced vector potentials. We find that the cooperation between the vector potential and superfluid order breaks the spatial symmetry of the system, and flourish stripe-ordered Fulde-Ferrell-Larkin-Ovchinnikov (FFLO)-like superfluid and supersolid phases that can be distinguished and characterized according to their coexisting pair-density (PDW), charge-density (CDW) and spin-density (SDW) wave orders. We also discuss confined systems and comment on the likelihood of observing such stripe-ordered phases by loading neutral atomic Fermi gases on laser-induced optical lattices under laser-generated artificial gauge fields.

description: A new tetrapyridine ligand, 5,5′-(3-pyridyl)-2,2′-bipyridine (2) was prepared from 5,5′-dibromo-2,2′-bipyridine (1) via Pd(0)-mediated Suzuki coupling. The reaction was performed either directly upon the free ligand, or upon its Ru(II) complex. The structures of [Ru(1)3](PF6)2 and [Ru(2)3](PF6)2 were studied in solution by NMR, and in the solid state by single crystal X-ray diffraction. Solution NMR data suggests distorted structures, consistent with the observed slow reactivity of the ligands towards Ru(II) ions, and their reluctance to coordinate to Fe(II) ions. However, solid-state X-ray data indicated little distortion from ideal geometries, suggesting the effect may be more electronic than steric in nature.

O culto do touro em Portugal é de longa tradição, como um conjunto de documentos do século XVIII, tanto administrativos como memórias literárias, também atesta. A sua popularidade é abundantemente corroborada, com todos os sectores da sociedade a disputar lugar na assistência para usufruir de um programa completo, que se distribuía por vários dias, ligado frequentemente a uma ocasião notável. Desse programa constavam: música, danças, carros de triunfo, combate de touros e diversos divertimentos taurinos. Infere-se o fausto dos figurinos, a imponência dos carros, o colosso das máquinas. A isto adiciona-se a morte de mais de uma vintena de touros por tarde, à espada, ao rojão, à faca. Entre a facécia e o sangue, o público exulta, participando na representação de uma sociedade histriónica e saciada.

Abstract:

The bull’s endorsement in Portugal has a long tradition, as underlined by a collection of administrative documents and literary memories from the eighteenth century. The popularity of this kind of entertainment is well-attested, since everyone readily disputed a good seat for a complete program of several days, frequently associated with a solemnity. There, the public could find a good array of music, dance, allegoric cars, bull fight and other bull distractions. One can easily infer the luxury of the garments, the majesty of the cars and the gigantic proportion of the machinery. To this, it must be added the killing of more than twenty bulls for afternoon, with the sword, rojão and knife. Between laugh and blood, the public exults, giving rise to the representation of a joyful and totally indulged society.

description: We present Gemini spectroscopy for 21 candidate optical counterparts to X-ray sources discovered in the Galactic Bulge Survey (GBS). For the majority of the 21 sources, the optical spectroscopy establishes that they are indeed the likely counterparts. One of the criteria we used for the identification was the presence of an Ha emission line. The spectra of several sources revealed an Ha emission line only after careful subtraction of the F or G stellar spectral absorption lines. In a sub-class of three of these sources the residual Halpha emission line is broad (> 400 km/s) which suggests that it is formed in an accretion disk, whereas in other cases the line width is such that we currently cannot determine whether the line emission is formed in an active star/binary or in an accretion disk. GBS source CX377 shows this hidden accretion behaviour most dramatically. The previously-identified broad Ha emission of this source is not present in its Gemini spectra taken about 1 year later. However, broad emission is revealed after subtracting an F6 template star spectrum. The Gemini spectra of three sources (CX446, CX1004, and CXB2) as well as the presence of possible eclipses in light curves of these sources suggest that these sources are accreting binaries viewed under a high inclination.

description: A clinical trial is a study that evaluates new biomedical interventions. To design new trials, researchers draw inspiration from those current and completed. In 2022, there were on average more than 100 clinical trials submitted to ClinicalTrials.gov every day, with each trial having a mean of approximately 1500 words [1]. This makes it nearly impossible to keep up to date. To mitigate this issue, we have created a batch clinical trial summarizer called CliniDigest using GPT-3.5. CliniDigest is, to our knowledge, the first tool able to provide real-time, truthful, and comprehensive summaries of clinical trials. CliniDigest can reduce up to 85 clinical trial descriptions (approximately 10,500 words) into a concise 200-word summary with references and limited hallucinations. We have tested CliniDigest on its ability to summarize 457 trials divided across 27 medical subdomains. For each field, CliniDigest generates summaries of $μ=153,\ σ=69 $ words, each of which utilizes $μ=54\%,\ σ=30\% $ of the sources. A more comprehensive evaluation is planned and outlined in this paper.

description: The synthesis of one symmetric and one non-symmetric ligand based on imide, quinoxaline and pyrazine moieties are reported. The symmetric ligand, N-(2-quinoxalylcarbonyl)-2-quinoxalinecarboxamide (Hquinoxquinox), is structurally characterised as Hquinoxquinox·d6DMSO. The non-symmetric ligand, N-(2-pyrazylcarbonyl)-2-quinoxalinecarboxamide (HLquinoxpz), was used to prepare the cobalt(II) complex [CoII(quinoxpz)2]·CH3OH, which was observed to remain high spin at 90 K. The structures of HLquinoxquinox·d6DMSO and [CoII(quinoxpz)2]·CH3OH are evaluated with regard to their potential to produce spin crossover (SCO) behaviour and for the construction of three-dimensional coordination polymers.

description: Science, Technology and Innovation (STI) decision-makers often need to have a clear vision of what is researched and by whom to design effective policies. Such a vision is provided by effective and comprehensive mappings of the research activities carried out within their institutional boundaries. A major challenge to be faced in this context is the difficulty in accessing the relevant data and in combining information coming from different sources: indeed, traditionally, STI data has been confined within closed data sources and, when available, it is categorised with different taxonomies. Here, we present a proof-of-concept study of the use of Open Resources to map the research landscape on the Sustainable Development Goal (SDG) 13-Climate Action, for an entire country, Denmark, and we map it on the 25 ERC panels.

description: Nonclassicality, entanglement, as well as dimensionality of a noisy twin beam are determined using characteristic function of the beam written in the Fock basis. One-to-one correspondence between the negativity quantifying entanglement and the nonclassicality depth is revealed. Twin beams, which are either entangled or nonclassical (independent of their entanglement), are observed only for the limited degrees of noise that degrades their quantumness. Dimensionality of the twin beam quantified by the participation ratio is compared with the dimensionality of entanglement determined from the negativity. The partition of the degrees of freedom of the twin beam into those related to entanglement and to noise is suggested. Both single-mode and multimode twin beams are analyzed. Weak nonclassicality based on integrated-intensity quasidistributions of multimode twin beams is studied. Relation of the model to the experimental twin beams is discussed.

description: Trajectory design in highly-perturbed environments like binary asteroids is challenging. It typically requires using realistic, non-autonomous dynamical models in which periodic solutions derived in autonomous systems vanish. In this work, Lagrangian descriptors are employed in the perturbed planar bi-elliptic restricted four-body problem to find regions of bounded motion over a finite horizon about Dimorphos, the secondary body of the (65803) Didymos binary system. Results show that Lagrangian descriptors successfully reveal phase space organizing structures both in the unperturbed and perturbed planar bi-elliptic restricted four-body problem. With no solar radiation pressure, regions of bounded motion are visually identified, so granting access to a vast selection of bounded orbits about Dimorphos. Conversely, the presence of solar radiation pressure breaks down the majority of structures, leading to a large region of unstable motion with rare exceptions. Lagrangian descriptors are computationally inexpensive dynamical indicators that could be conveniently applied to astrodynamics.

description: Four new compounds prepared from the ligand 2,3-dipyridyl ketone oxime (L23) with varying Cu(II) salts were synthesised and structurally characterised, {[Cu(L23)(L23-H)](ClO4)}∞ (1), {[Cu(L23)(L23-H)](BF4)¼(H2O)}∞ (2), [Cu3(L23-H)2(L23′)(NO3)2OH]2(NO3)2(C3H8O)6 (3) and [Cu(L23)Cl2]∞ (4). The effects of differing counterions, as well as the rotational conformational versatility of L23, were demonstrated by the differing polymeric structures that were observed. Complex 1 and 2 both existed as 1-D polymeric chains with L23 acting as a pseudo-tetradentate ligand through an oxime–oximato bridge. Complex 1 formed a helical arrangement while 2 formed a chiral chain with both 1 and 2 exhibiting similar chiral packing. Complex 3 formed an unusual inverse–9–metallacrown–3 complex, with one of the L23 ligands in a zwitterionic form. Complex 4 was present as a simple 1-D meso-helical chain.

description: We analyze free expansion of a trapped one-dimensional Bose gas after a sudden release from the confining trap potential. By using the stationary phase and local density approximations, we show that the long-time asymptotic density profile and the momentum distribution of the gas are determined by the initial distribution of Bethe rapidities (quasimomenta) and hence can be obtained from the solutions to the Lieb-Liniger equations in the thermodynamic limit. For expansion from a harmonic trap, and in the limits of very weak and very strong interactions, we recover the self-similar scaling solutions known from the hydrodynamic approach. For all other power-law traps and arbitrary interaction strengths, the expansion is not self-similar and shows strong dependence of the density profile evolution on the trap anharmonicity. We also characterize dynamical fermionization of the expanding cloud in terms of correlation functions describing phase and density fluctuations.

description: The role played by the circulating libraries in the history of library provision is unique to Britain. There was no similar development on a comparable scale in either Europe or America. The circulating libraries bridged the gap from the period when books were almost the exclusive province of the rich to the present situation of a national free public library service. During this transitional period there were great social, economic and political changes which reflected upon and were reflected by the progress of the circulating libraries. The literature on these libraries has tended to be dominated by the 'leviathan', Charles Mudie's 'Select Library', whilst comparatively scant attention has been paid to W.H. Smith and Son's library. This has resulted in a neglect of the major and unique contribution made by this library to library history. The aim of this study is to rectify that situation.

description: Computational techniques allow insights into chemical processes that are normally experimentally difficult to access (e.g. transition states). Here, we report on the computational modelling of a recently reported supramolecular system that experimentally displays a complex mixture of cooperative, allosteric, homotropic and heterotropic binding behaviour in the interactions of two calcium cations and two chloride anions with a tetratopic ion-pairing host (bis-isophthalamide-crown-6) H. Using DFT, we are able to predict the structural conformations and binding energies of the multi-step thermodynamic binding cycle in both directions for the formation of the quinary 2Ca2+·H·2Cl− complex in both vacuum and solvent environments with several key steps validated against experimental X-ray and binding study data. This study revealed unexpected conformational changes in the free host upon binding two Cl− anions, with a tetra-coordinated (four hydrogen-bonds) 1:1 H·Cl− complex forming before the expected bis(isopthhalimide-Cl−) 1:2 H·2Cl− complex with two hydrogen bonds is formed. The results here show that given the appropriate method (basis set, solvent environment) DFT calculations can both predict and give unique insight into multi-ion host supramolecular interactions like those encountered in ion-pair host–guest studies.

description: We study telecom-wavelength spectra of a Rydberg state in an atomic vapor with a three-photon excitation scheme. Two lasers of 780 nm and 776 nm are used to pump Rubidium-85 atoms in a vapor cell to the $5D_{\mathrm{5/2}}$ state, from which a probe beam of 1292 nm in the O-band telecommunication wavelength drives a transition to the $21F_{\mathrm{7/2}}$ Rydberg state. We investigate the probe spectra over the power of pump lasers. The simulation based on a 4-level theoretical model captures the main features of the experimental results. This spectroscopic study paves the way for future experiments of making a direct link between fiber optics and radio transmission via Rydberg atoms.

description: A diaryl-linked tripyridyl ligand (L), 2,6-bis[4-(3-pyridinyl)phenyl]-4-(hydroxymethyl)pyridine, was synthesised in good yield (57%) exploiting the Pd-catalysed Suzuki cross-coupling method and used to assemble a new [Pd2L4]4+ metallosupramolecular cage architecture. These systems have been characterised by NMR, IR and UV–vis spectroscopies, mass spectrometry, elemental analysis and by X-ray crystallography. It was shown using NMR spectroscopy and X-ray crystallography that the cage acts as a host for anions. However, efforts to bind the anticancer drug cisplatin within the central cavity of the cage were unsuccessful. This appears to be connected to steric effects caused by the aryl spacer units of the ligands forming the cage.

description: The Robot Operating System 2 (ROS 2) is rapidly impacting the intelligent machines sector -- on space missions, large agriculture equipment, multi-robot fleets, and more. Its success derives from its focused design and improved capabilities targeting product-grade and modern robotic systems. Following ROS 2's example, the mobile robotics ecosystem has been fully redesigned based on the transformed needs of modern robots and is experiencing active development not seen since its inception. This paper comes from the desks of the key ROS Navigation maintainers to review and analyze the state of the art of robotics navigation in ROS 2. This includes new systems without parallel in ROS 1 or other similar mobile robotics frameworks. We discuss current research products and historically robust methods that provide differing behaviors and support for most every robot type. This survey consists of overviews, comparisons, and expert insights organized by the fundamental problems in the field. Some of these implementations have yet to be described in literature and many have not been benchmarked relative to others. We end by providing a glimpse into the future of the ROS 2 mobile robotics ecosystem.

description: We report on highly tunable radio frequency (rf) characteristics of a low-loss and compact three dimensional (3D) metamaterial made of superconducting thin film spiral resonators. The rf transmission spectrum of a single element of the metamaterial shows a fundamental resonance peak at $\sim$24.95 MHz that shifts to a 25$\%$ smaller frequency and becomes degenerate when a 3D array of such elements is created. The metamaterial shows an $\emph{in-situ}$ tunable narrow frequency band in which the real part of the effective permeability is negative over a wide range of temperature, which reverts to gradually near-zero and positive values as the superconducting critical temperature is approached. This metamaterial can be used for increasing power transfer efficiency and tunability of electrically small rf-antennas.

description: Hardening is the process of configuring IT systems to ensure the security of the systems' components and data they process or store. The complexity of contemporary IT infrastructures, however, renders manual security hardening and maintenance a daunting task. In many organizations, security-configuration guides expressed in the SCAP (Security Content Automation Protocol) are used as a basis for hardening, but these guides by themselves provide no means for automatically implementing the required configurations. In this paper, we propose an approach to automatically extract the relevant information from publicly available security-configuration guides for Windows operating systems using natural language processing. In a second step, the extracted information is verified using the information of available settings stored in the Windows Administrative Template files, in which the majority of Windows configuration settings is defined. We show that our implementation of this approach can extract and implement 83% of the rules without any manual effort and 96% with minimal manual effort. Furthermore, we conduct a study with 12 state-of-the-art guides consisting of 2014 rules with automatic checks and show that our tooling can implement at least 97% of them correctly. We have thus significantly reduced the effort of securing systems based on existing security-configuration guides.

description: The cores of main sequence intermediate- and high-mass stars are convective. Mixing at the radiative-convective boundary, waves excited by the convection, and magnetic fields generated by convective dynamos all influence the main sequence and post-main sequence evolution of these stars. These effects must be understood to accurately model the structure and evolution of intermediate- and high-mass stars. Unfortunately, there are many challenges in simulating core convection due to the wide range of temporal and spatial scales, as well as many important physics effects. In this review, we describe the latest numerical strategies to address these challenges. We then describe the latest state-of-the-art simulations of core convection, summarizing their main findings. These simulations have led to important insights into many of the processes associated with core convection. Two outstanding problems with multidimensional simulations are, 1. it is not always straightforward to extrapolate from simulation parameters to the parameters of real stars; and 2. simulations using different methods sometimes appear to arrive at contradictory results. To address these issues, next generation simulations of core convection must address how their results depend on stellar luminosity, dimensionality, and turbulence intensity. Furthermore, code comparison projects will be essential to establish robust parameterizations that will become the new standard in stellar modeling.

description: In the earliest phases of their evolution, stars gain mass through the acquisition of matter from their birth clouds. The widely accepted classical concept of early stellar evolution neglects the details of this accretion phase and assumes the formation of stars with large initial radii that contract gravitationally. In this picture, the common idea is that once the stars begin their fusion processes, they have forgotten their past. By analysing stellar oscillations in recently born stars, we show that the accretion history leaves a potentially detectable imprint on the stars' interior structures. Currently available data from space would allow discriminating between these more realistic accretion scenarios and the classical early stellar evolution models. This opens a window to investigate the interior structures of young pulsating stars that will also be of relevance for related fields, such as stellar oscillations in general and exoplanet studies.

description: We review the recent progress made in studies of deuteron structure at small internucleon distances. This progress is largely facilitated by the new generation of experiments in deuteron electrodisintegration carried out at unprecedentedly high momentum transfer. The theoretical analysis of these data confirms the onset of the high energy eikonal regime in the scattering process which allows one to separate long range nuclear effects from the effects genuinely related to the short distance structure of the deuteron. Our conclusion is that for the first time the deuteron is probed at relative momenta beyond 300 MeV/c without dominating long range effects. As a result, at these large nucleon momenta the cross section is sensitive to the nuclear dynamics at sub-fermi distances. Due to large internal momenta involved we are dealing with the relativistic bound state that is best described by the light-cone momentum distribution of nucleons in the deuteron. We present the first attempt of extracting the deuteron light-cone momentum distribution function from data and discuss the importance of this quantity for studies of QCD structure of the bound nucleon in deep inelastic scattering off the deuteron. We conclude the review giving an outlook of the next generation of high energy experiments which will extend our reach to much smaller distances in the deuteron.
