description: Ex vivo studies of human disease, such as acute myeloid leukemia, are generally limited to the analysis of two-dimensional cultures which often misinterpret the effectiveness of chemotherapeutics and other treatments. Here we show that matrix metalloproteinase-sensitive hydrogels prepared from poly(ethylene glycol) and heparin functionalized with adhesion ligands and pro-angiogenic factors can be instrumental to produce robust three-dimensional culture models, allowing for the analysis of acute myeloid leukemia development and response to treatment. We evaluated the growth of four leukemia cell lines, KG1a, MOLM13, MV4-11 and OCI-AML3, as well as samples from patients with acute myeloid leukemia. Furthermore, endothelial cells and mesenchymal stromal cells were co-seeded to mimic the vascular niche for acute myeloid leukemia cells. Greater drug resistance to daunorubicin and cytarabine was demonstrated in three-dimensional cultures and in vascular co-cultures when compared with two-dimensional suspension cultures, opening the way for drug combination studies. Application of the C-X-C chemokine receptor type 4 (CXCR4) inhibitor, AMD3100, induced mobilization of the acute myeloid leukemia cells from the vascular networks. These findings indicate that the three-dimensional tri-culture model provides a specialized platform for the investigation of cell-cell interactions, addressing a key challenge of current testing models. This ex vivo system allows for personalized analysis of the responses of patients’ cells, providing new insights into the development of acute myeloid leukemia and therapies for this disease.

description: In this paper we address the problem to compute state dependent feedback controls for path integral control problems. To this end we generalize the path integral control formula and utilize this to construct parameterized state dependent feedback controllers. In addition, we show a novel relation between control and importance sampling: better control, in terms of control cost, yields more efficient importance sampling, in terms of effective sample size. The optimal control provides a zero-variance estimate.

description: Background People with intellectual disabilities are over-represented in the criminal justice system. The United Nations’ Convention on the Rights of Persons with Disabilities (UNCRPD) enshrines a right to equal access to justice for persons with disabilities (Article 13, UNCRPD). Accessible information is a key aspect of exercising this right. Yet, many jurisdictions, including Ireland, are yet to develop accessible information for disabled people who may be arrested. Aims This paper describes the collaborative development through multidisciplinary and advocate consensus of an accessible (Easy -to- Read) Notice of Rights (ERNR) for people with intellectual disabilities in police custody in Ireland. Methods Guidelines developed by Ireland’s representative organisation for people with intellectual disabilities and examples of international practice were used to develop a draft ERNR by the primary researcher in partnership with an expert from a representative organisation for people with intellectual disabilities. The ERNR was developed thereafter through two focus groups with a view to achieving consensus with a focus on accessibility, accuracy and layout. This included a multidisciplinary focus group with participants from a representative organisation for people with intellectual disabilities, psychology, speech and language therapy, the police force, public health, forensic psychiatry, mental health, law and, subsequently, a focus group of people with lived experience of intellectual disability. Results Progressive development of the ERNR resulted in incremental improvements in textual accuracy as well as the inclusion of more accessible language and imagery. Originality/value This is the first attempt at developing an easy-to-read document relating to the legal rights of suspects in police custody in Ireland and, accordingly, this procedural innovation promises to assist, not just persons with intellectual disabilities, but also those with limited literacy at the point of arrest. The methodology used in the preparation of the document, employing a focus group to achieve consensus with participation from both multiple disciplines and persons with an intellectual disability, is in harmony with the ethos of the UNCPRD. This methodology may usefully be employed by other member states that have ratified the Convention but have yet to develop accessible version of the legal rights and entitlements that extend to arrested persons under their domestic law.

description: Non-public networks (NPNs) push the integration capability of 5G a step further by not only offering the integration of service capabilities specific and tuned towards verticals but building an entire concept of infrastructure provisioning around verticals. This is achieved by extending the architectural alignment of service-based architecture and enterprise service architecture to the capability of provisioning 5G hardware infrastructure, down to base stations in vertical industry sites. The use of private site-specific spectrum, utilized for 5G infrastructure, can be complemented by the possibility to utilize roaming into operators’ wide-area connectivity, if needed for the specific use case. The use of local spectrum disconnects NPNs entirely from previous operator-dependent deployment models. Ultimately, the vertical customer’s extended enterprise service architecture is now realized as a distributed data centre that spans its various sites albeit with the ultra-low latency and service-centric capabilities that are enabled by 5G. This white paper presents the state of the art of NPNs in the 5G and beyond 5G context and provides an outlook on possible evolution paths of this concept.

description: Asimple and versatilemethod is reported for the noncovalent functionalisation of natural and "green" halloysite nanotubes (HNTs) allowing their effective dispersion in a polystyrene (PS) thermoplastic matrix via solvent mixing. Initially, HNTs (pristine HNTs) were modified with physically adsorbed surfactant molecules of sodium dodecyl sulphate (SDS) and PS-b-P4VP [P4VP: poly(4-vinylpyridine)] block copolymer (BCP). Hereafter, SDS and BCP modified HNTs will be indicated as SDS-m-HNT and BCP-m-HNT.Nanocomposite films with 1, 2, and 5 wt.%HNTloadingswere prepared, abbreviated as PS-SDS-m-HNT1, PS-SDS-m-HNT2, and PS-SDS-m-HNT5 and PS-BCP-m-HNT1, PS-BCP-m-HNT2, and PS-BCP-m-HNT5 (where 1, 2, and 5 correspond to the wt.% of HNTs). All nanocomposites depicted improved thermal degradation compared to the neat PS as revealed by thermogravimetric analysis (TGA). Transmission electron microscopy (TEM) confirmed the good dispersion state of HNTs and the importance of modification by SDS and BCP. X-ray diffraction (XRD) studies showed the characteristic interlayer spacing between the two silicate layers of pristine and modified HNTs. The PS/HNT nanocomposite films exhibited excellent ultraviolent-visible (UV-vis) absorbance properties and their potential application as UV-filters could be envisaged.

description: We present sMolBoxes, a dataflow representation for the exploration and analysis of long molecular dynamics (MD) simulations. When MD simulations reach millions of snapshots, a frame-by-frame observation is not feasible anymore. Thus, biochemists rely to a large extent only on quantitative analysis of geometric and physico-chemical properties. However, the usage of abstract methods to study inherently spatial data hinders the exploration and poses a considerable workload. sMolBoxes link quantitative analysis of a user-defined set of properties with interactive 3D visualizations. They enable visual explanations of molecular behaviors, which lead to an efficient discovery of biochemically significant parts of the MD simulation. sMolBoxes follow a node-based model for flexible definition, combination, and immediate evaluation of properties to be investigated. Progressive analytics enable fluid switching between multiple properties, which facilitates hypothesis generation. Each sMolBox provides quick insight to an observed property or function, available in more detail in the bigBox View. The case study illustrates that even with relatively few sMolBoxes, it is possible to express complex analyses tasks, and their use in exploratory analysis is perceived as more efficient than traditional scripting-based methods.

description: We have constructed a series of non-rotating quasi-hydrostatic evolutionary models for the M2 Iab supergiant Betelgeuse ($α~Orionis$). Our models are constrained by multiple observed values for the temperature, luminosity, surface composition and mass loss for this star, along with the parallax distance and high resolution imagery that determines its radius. We have then applied our best-fit models to analyze the observed variations in surface luminosity and the size of detected surface bright spots as the result of up-flowing convective material from regions of high temperature in the surface convective zone. We also attempt to explain the intermittently observed periodic variability in a simple radial linear adiabatic pulsation model. Based upon the best fit to all observed data, we suggest a best progenitor mass estimate of $ 20 ^{+5}_{-3} M_\odot$ and a current age from the start of the zero-age main sequence of $8.0 - 8.5$ Myr based upon the observed ejected mass while on the giant branch.

description: The dihydroxycarbonyls 3,4-dihydroxy-2-butanone (DHBO) and 2,3-dihydroxy-2-methylpropanal (DHMP) formed from isoprene oxidation products in the atmospheric gas phase under low-NO conditions can be expected to form aqSOA in the tropospheric aqueous phase because of their solubility. In the present study, DHBO and DHMP were investigated concerning their radical-driven aqueous-phase oxidation reaction kinetics. For DHBO and DHMP the following rate constants at 298 K are reported: k(OH + DHBO) = (1.0 ± 0.1) × 109 L mol-1 s-1, k(NO3 + DHBO) = (2.6 ± 1.6) × 106 L mol-1 s-1, k(SO4-+ DHBO) = (2.3 ± 0.2) × 107 L mol-1 s-1, k(OH + DHMP) = (1.2 ± 0.1) × 109 L mol-1 s-1, k (NO3 + DHMP) = (7.9 ± 0.7) × 106 L mol-1 s-1, k(SO4- + DHMP) = (3.3 ± 0.2) × 107 L mol-1 s-1, together with their respective temperature dependences. The product studies of both DHBO and DHMP revealed hydroxydicarbonyls, short chain carbonyls, and carboxylic acids, such as hydroxyacetone, methylglyoxal, and lactic and pyruvic acid as oxidation products with single yields up to 25%. The achieved carbon balance was 75% for DHBO and 67% for DHMP. An aqueous-phase oxidation scheme for both DHBO and DHMP was developed on the basis of the experimental findings to show their potential to contribute to the aqSOA formation. It can be expected that the main contribution to aqSOA occurs via acid formation while other short-chain oxidation products are expected to back-partition into the gas phase to undergo further oxidation there.

description: The Sun cubE onE (SEE) is a 12U CubeSat mission proposed for a phase A/B study to the Italian Space Agency that will investigate Gamma and X-ray fluxes and ultraviolet (UV) solar emission to support studies in Sun-Earth interaction and Space Weather from LEO. More in detail, SEE's primary goals are to measure the flares emission from soft-X to Gamma ray energy range and to monitor the solar activity in the Fraunhofer Mg II doublet at 280 nm, taking advantage of a full disk imager payload. The Gamma and X-ray fluxes will be studied with unprecedented temporal resolution and with a multi-wavelength approach thanks to the combined use of silicon photodiode and silicon photomultiplier (SiPM) -based detectors. The flare spectrum will be explored from the keV to the MeV range of energies by the same payload, and with a cadence up to 10 kHz and with single-photon detection capabilities to unveil the sources of the solar flares. The energy range covers the same bands used by GOES satellites, which are the standard bands for flare magnitude definition. At the same time SiPM detectors combined with scintillators allow to cover the non-thermal bremsstrahlung emission in the gamma energy range. Given its UV imaging capabilities, SEE will be a key space asset to support detailed studies on solar activity, especially in relation to ultraviolet radiation which strongly interacts with the upper layers of the Earth's atmosphere, and in relation to space safety, included in the field of human space exploration. The main goal for the UV payload is to study the evolution of the solar UV emission in the Mg II band at two different time scales: yearly variations along the solar cycle and transient variations during flare events.

description: The elliptic flow splitting between particles and their antiparticles has recently been observed by the STAR Collaboration in the beam-energy scan program at the Relativistic Heavy Ion Collider. In studies based on transport models, we have found that this splitting can be explained by the different mean-field potentials acting on particles and their antiparticles in the produced baryon-rich matter. In particular, we have shown that the experimentally measured relative elliptic flow difference can help constrain the vector coupling constant in the Nambu-Jona-Lasinio model used in describing the partonic stage of heavy-ion collisions. This information is useful for locating the critical point in the QCD phase diagram and thus understanding the phase structure of QCD.

description: The focus of this work is on the nature of self-healing of ionically modified rubbers obtained by reaction of brominated poly(isobutylene-co-isoprene) rubber (BIIR) with various alkylimidazoles such as 1-methylimidazole, 1-butylimidazole, 1-hexylimidazole, 1-nonylimidazole, and 1-(6-chlorohexyl)-1H-imidazole. Based on stress-strain and temperature dependent DMA measurements, a structural influence of the introduced ionic imidazolium moieties on the formation of ionic clusters and, as a consequence, on the mechanical strength and self-healing behavior of the samples could be evidenced. These results are fully supported by a molecular-level assessment of the network structure (cross-link and constraint density) and the dynamics of the ionic clusters using an advanced proton low-field NMR technique. The results show distinct correlations between the macroscopic behavior and molecular chain dynamics of the modified rubbers. In particular, it is shown that the optimization of material properties with regard to mechanical and self-healing behavior is limited by opposing tendencies. Samples with reduced chain dynamics exhibit superior mechanical behavior but lack on self-healing behavior. In spite of these limitations, the overall performance of some of our samples including self-healing behavior exceeds distinctly that of other self-healing rubbers described in the literature so far.

description: The role of instanton-like objects in the QCD vacuum on the mass spectrum of low-lying light hadrons is explored in lattice QCD. Using over-improved stout-link smearing, tuned to preserve instanton-like objects in the QCD vacuum, the evolution of the mass spectrum under smearing is examined. The calculation is performed using a $20^3\times40$ dynamical fat-link-irrelevant-clover (FLIC) fermion action ensemble with lattice spacing 0.126 fm. Through the consideration of a range of pion masses, the effect of the vacuum instanton content is compared at a common pion mass. While the qualitative features of ground-state hadrons are preserved on instanton-dominated configurations, the excitation spectrum experiences significant changes. The underlying physics revealed shows little similarity to the direct-instanton interaction predictions of the instanton liquid model.

description: We study the specific heat of a model supercooled liquid confined in a spherical cavity with amorphous boundary conditions. We find the equilibrium specific heat has a cavity-size-dependent peak as a function of temperature. The cavity allows us to perform a finite-size scaling (FSS) analysis, which indicates that the peak persists at a finite temperature in the thermodynamic limit. We attempt to collapse the data onto a FSS curve according to different theoretical scenarios, obtaining reasonable results in two cases: a "not-so-simple" liquid with nonstandard values of the exponents α and ν, and random first-order theory, with two different length scales.

description: Surface heterogeneities, including roughness, significantly affect the adsorption, motion and interactions of particles at fluid interfaces. However, a systematic experimental study, linking surface roughness to particle wettability at a microscopic level, is currently missing. Here we synthesize a library of all-silica microparticles with uniform surface chemistry, but tuneable surface roughness and study their spontaneous adsorption at oil-water interfaces. We demonstrate that surface roughness strongly pins the particles' contact lines and arrests their adsorption in long-lived metastable positions, and we directly measure the roughness-induced interface deformations around isolated particles. Pinning imparts tremendous contact angle hysteresis, which can practically invert the particle wettability for sufficient roughness, irrespective of their chemical nature. As a unique consequence, the same rough particles stabilize both water-in-oil and oil-in-water emulsions depending on the phase they are initially dispersed in. These results both shed light on fundamental phenomena concerning particle adsorption at fluid interfaces and indicate future design rules for particle-based emulsifiers.

description: 1H 0323+342 is optically one of the nearest and brightest very radio loud narrow line Seyfert 1 galaxies (vRL NLSy1). It is also one of the first vRLNLSy1s detected at gamma-ray energies by the Fermi-LAT. We report the results of monitoring the optical flux of 1H 0323+342 during more than six and a half years. In some cases, we, for the first time, simultaneously use two telescopes to monitor the optical flux of 1H 0323+342 on timescales ranging from minutes to hours, demonstrating the reality of low amplitude microvariability whole events with durations of a few hours for this object. Based on the present results, as well as those of earlier studies, we suggest that this represents a fundamental timescale associated with the underlying source region. We also present an enhancement of Howell's comparison star method for detecting microvariability.

In this article, we study variants T_X^a of the full transformation semigroup T_X on a finite set X. We explore the structure of T_X^a as well as its subsemigroups Reg(T_X^a) (consisting of all regular elements) and E_X^a (consisting of all products of idempotents), and the ideals of Reg(T_X^a). Among other results, we calculate the rank and idempotent rank (if applicable) of each semigroup, and (where possible) the number of (idempotent) generating sets of the minimal possible size.

We provide some examples showing that the limsup value (and the uniform value) may not exist in general. Then we show the existence of the value for any Borel payoff function if the players observe a public signal including the actions played. We also prove two other positive results without assumptions on the signaling structure: the existence of the $\sup$ value in any game and the existence of the uniform value in recursive games with nonnegative payoffs.

These turn out to be parametrized by the group of Weyl-invariant quadratic forms on the cocharacter lattice valued in $k^\times$ and the group of integral Weyl-invariant cubic forms on the cocharacter lattice respectively.

description: Τα τελευταία χρόνια, η Εταιρική Υπευθυνότητα αρχίζει να αποκτά ολοένα και πιο βαρύνουσα σημασία για τις επιχειρήσεις, καθώς πλέον μοναδικός στόχος δεν είναι η οικονομική απόδοση, αλλά και η ανταπόκριση σε μια βασική πρόκληση της εποχής, που δεν είναι άλλη από τη βιώσιμη ανάπτυξη. Θερμοί υποστηρικτές της νέας αυτής προσέγγισης του ρόλου των επιχειρήσεων αποτελούν πρωτίστως οι καταναλωτές, οι επενδυτές, οι προμηθευτές, αλλά και οι εργαζόμενοι οι οποίοι ασκούν πίεση ώστε να συμπεριληφθούν στην εταιρική πολιτική και στοχοθεσία, ζητήματα κοινωνικά και περιβαλλοντικά.
Για να ανταποκριθούν οι επιχειρήσεις στα νέα αυτά δεδομένα, είναι απαραίτητο να επιδεικνύουν συνεχή βελτίωση στο τρίπτυχο: οικονομική, κοινωνική και περιβαλλοντική απόδοση μέσα σε νέα και εξελισσόμενα συστήματα διακυβέρνησης. Για το σκοπό αυτό, επιχειρήσεις και οργανισμοί επενδύουν πόρους στην ανάπτυξη δράσεων που θα αποσκοπούν στη ανάπτυξη του κοινωνικού συνόλου, στη κάλυψη αναγκών ευπαθών ομάδων και στη λήψη μέτρων που θα συντελούν στη μείωση των ρύπων του περιβάλλοντος, προβάλλοντας έτσι την υπευθυνότητα και τη κοινωνική τους ευσυνειδησία.

Στη παρούσα Διπλωματική Εργασία αναπτύσσεται η έννοια της Εταιρικής Κοινωνικής Ευθύνης (ΕΚΕ) και γίνεται παρουσίαση των εννοιών που τη συνοδεύουν. Στη συνέχεια, αναλύονται τα οφέλη, το κόστος αλλά και η σχέση που υπάρχει μεταξύ της ανάπτυξης δράσεων ΕΚΕ και της χρηματοοικονομικής επίδοσης των εταιρειών. Τέλος, αξιοποιώντας και αναλύοντας αναφορές εταιρειών από διαθέσιμες πηγές (όπως τα Global Initiative Reports) διαμορφώνονται δείκτες επίδοσης ως προς τις διαστάσεις της ΕΚΕ (περιβάλλον, κοινωνία κ.λπ.). Οι δείκτες αυτοί αναλύονται περαιτέρω μέσω πολυκριτήριας ανάλυσης, ώστε να γίνει η αξιολόγηση και συγκριτική μελέτη της επίδοσης των εταιρειών, ως προς τις δράσεις που προάγουν την εταιρική υπευθυνότητα.

description: Functions preserving Loewner positivity when applied entrywise to positive semidefinite matrices have been widely studied in the literature. Following the work of Schoenberg [Duke Math. J. 9], Rudin [Duke Math. J. 26], and others, it is well-known that functions preserving positivity for matrices of all dimensions are absolutely monotonic (i.e., analytic with nonnegative Taylor coefficients). In this paper, we study functions preserving positivity when applied entrywise to sparse matrices, with zeros encoded by a graph $G$ or a family of graphs $G_n$. Our results generalize Schoenberg and Rudin's results to a modern setting, where functions are often applied entrywise to sparse matrices in order to improve their properties (e.g. better conditioning). The only such result known in the literature is for the complete graph $K_2$. We provide the first such characterization result for a large family of non-complete graphs. Specifically, we characterize functions preserving Loewner positivity on matrices with zeros according to a tree. These functions are multiplicatively midpoint-convex and super-additive. Leveraging the underlying sparsity in matrices thus admits the use of functions which are not necessarily analytic nor absolutely monotonic. We further show that analytic functions preserving positivity on matrices with zeros according to trees can contain arbitrarily long sequences of negative coefficients, thus obviating the need for absolute monotonicity in a very strong sense. This result leads to the question of exactly when absolute monotonicity is necessary when preserving positivity for an arbitrary class of graphs. We then provide a stronger condition in terms of the numerical range of all symmetric matrices, such that functions satisfying this condition on matrices with zeros according to any family of graphs with unbounded degrees are necessarily absolutely monotonic.

description: We experimentally investigate the relative advantages of implementing weak-value-based metrology versus standard methods. While the techniques outlined herein apply more generally, we measure small optical beam deflections both using a Sagnac interferometer with a monitored dark port (the weak-value-based technique), and by focusing the entire beam to a split detector (the standard technique). By introducing controlled external transverse detector modulations and transverse beam deflection momentum modulations, we quantify the mitigation of these sources in the weak-value-based experiment versus the standard focusing experiment. The experiments are compared using a combination of deterministic and stochastic methods. In all cases, the weak-values technique performs the same or better than the standard technique by up to two orders of magnitude in precision for our parameters. We further measure the statistical efficiency of the weak-values-based technique. By postselecting on $1\%$ of the photons, we obtain $99\%$ of the available Fisher information of the beam deflection parameter.

Quasi-Feynman formulas -- a method of obtaining the evolution operator for the Schroedinger equation

description: For a densely defined self-adjoint operator $\mathcal{H}$ in Hilbert space $\mathcal{F}$ the operator $\exp(-it\mathcal{H})$ is the evolution operator for the Schrödinger equation $iψ'_t=\mathcal{H}ψ$, i.e. if $ψ(0,x)=ψ_0(x)$ then $ψ(t,x)=(\exp(-it\mathcal{H})ψ_0)(x)$ for $x\in Q.$ The space $\mathcal{F}$ here is the space of wave functions $ψ$ defined on an abstract space $Q$, the configuration space of a quantum system, and $\mathcal{H}$ is the Hamiltonian of the system. In this paper the operator $\exp(-it\mathcal{H})$ for all real values of $t$ is expressed in terms of the family of self-adjoint bounded operators $S(t), t\geq 0$, which is Chernoff-tangent to the operator $-\mathcal{H}$. One can take $S(t)=\exp(-t\mathcal{H})$, or use other, simple families $S$ that are listed in the paper. The main theorem is proven on the level of semigroups of bounded operators in $\mathcal{F}$ so it can be used in a wider context due to its generality. Two examples of application are provided.

description: Caring has always been associated with nursing as its essence, core, and foundation in the nursing practice. Identifying the caring behaviors of nurses would give additional determinants to effective and excellent quality nursing care, patient safety, and patient satisfaction. The research design utilized is the descriptive-correlational quantitative method. The participants were assessed with the Caring Nurse Patient Interaction Scale (CNPI) and the Patient Satisfaction Instrument (PSI). The study was completed through the purposive sampling of 162 patients of the inpatient wards in a selected tertiary hospital in Riyadh, Saudi Arabia. The results showed that nurses' caring behavior as perceived by the patients had a mean score of 4.39 (SD=0.68) and patient satisfaction had a mean score of 3.97 (SD=0.50). There is a moderately high positive correlation (Pearson R=0.527;p=0.000) noted between the nurses' caring behavior as perceived by the patient and patient satisfaction. It could be concluded that patients were satisfied in the level of care received from the nurses in the hospital. They are more satisfied with how nurses value them and show their worth. However, they are not well satisfied with how nurses give respect to the perception of their health. Moreover, nurses must recognize the value of caring in relation to patients' satisfaction. They must give more emphasis on how to establish more rapport to build a stronger nurse-patient relationship.

description: The paper introduces hidden grid background oriented schlieren for quantitative study and visualization of natural convection heat transfer. In this technique, the refractive index variation, induced by the temperature gradient, is encoded in the recorded signal phase through the distortion of a background pattern. The background (undistorted) pattern is implicit (or hidden) in the light source. Quantitative estimation of the phase map is obtained by windowed Fourier transform. This method offers localized processing of the signal using joint space-frequency representation. The performance of hidden grid background oriented schlieren is practically demonstrated by investigating natural convective flow, a demanding task due to its comparatively small heat transfer.
Ground state entanglement constrains low-energy excitations

description: For a general quantum many-body system, we show that its ground-state entanglement imposes a fundamental constraint on the low-energy excitations. For two-dimensional systems, our result implies that any system that supports anyons must have a nonvanishing topological entanglement entropy. We demonstrate the generality of this argument by applying it to three-dimensional quantum many-body systems, and showing that there is a pair of ground state topological invariants that are associated to their physical boundaries. From the pair, one can determine whether the given boundary can or cannot absorb point-like or line-like excitations.

description: Se estudia el problema newtoniano de los n-cuerpos describiendo explícitamente las ecuaciones de movimiento que lo rigen, sus integrales clásicas y sus simetrías. Se muestra que en dicho problema general no existen soluciones de equilibrio, muchas veces llamadas puntos de equilibrio. Al considerar que la complejidad de los movimientos aumenta rápidamente con el número de masas, se analiza el problema con dos cuerpos haciendo una descripción cualitativa de todas sus soluciones. Unicamente cuando n = 2 , se conocen explícitamente todas las soluciones. Implicando que este problema en particular sea muy importante dentro de la Mecánica Celeste. También se hace mención de las soluciones particulares que se conocen del problema newtoniano de los n-cuerpos, las cuales dicho sea de paso, se obtienen de las Configuraciones Centrales.
