description: The flocking motion control is concerned with managing the possible conflicts between local and team objectives of multi-agent systems. The overall control process guides the agents while monitoring the flock-cohesiveness and localization. The underlying mechanisms may degrade due to overlooking the unmodeled uncertainties associated with the flock dynamics and formation. On another side, the efficiencies of the various control designs rely on how quickly they can adapt to different dynamic situations in real-time. An online model-free policy iteration mechanism is developed here to guide a flock of agents to follow an independent command generator over a time-varying graph topology. The strength of connectivity between any two agents or the graph edge weight is decided using a position adjacency dependent function. An online recursive least squares approach is adopted to tune the guidance strategies without knowing the dynamics of the agents or those of the command generator. It is compared with another reinforcement learning approach from the literature which is based on a value iteration technique. The simulation results of the policy iteration mechanism revealed fast learning and convergence behaviors with less computational effort.

description: Trabajadores y empleadores de vieja data han entendido que la huelga y el cese de actividades, además de ser un acto político en términos laborales, es un acto que, como la guerra, genera consecuencias y perjuicios a las partes. Resulta claro que al estar en juego derechos constitucionalmente admisibles, su ejercicio podrá generar perjuicios, por ejemplo, el cese puede conllevar a la materialización de daños debido a la parálisis de la actividad económica, no obstante, ello no implicará per se la indemnización de estos, incluso, en aquellos escenarios en los que se haya efectuado la declaratoria de ilegalidad del cese; cuestión diferente será en aquellos casos en los que se logre acreditar que se desbordó el ejercicio del derecho, ocasionando daños que el empleador no está en condiciones de soportar. Dicho lo anterior, este trabajo de investigación partirá del planteamiento sobre la procedencia o no de la indemnización de perjuicios en favor del empleador cuando ha sido declarada la ilegalidad de la suspensión colectiva del trabajo y, en consecuencia, se abordará la cuestión acerca de la competencia sobre el asunto, concluyendo que, al ser característico del derecho laboral, éste deberá ser de conocimiento de la jurisdicción ordinaria en su especialidad laboral.
description: Long-standing workers and employers have understood that the strike and the cessation of activities, in addition to being a political act in labor terms, is an act that, like war, generates consequences and damages to the parties. It is clear that, since constitutionally admissible rights are at stake, its execution may generate damages, for example, the strike may lead to the materialization of damages due to the paralysis of economic activity, however, this will not imply per se compensation for these, even, in those scenarios in which the declaration of illegality of the strike has been made; a different matter will be in those cases in which it is possible to prove that the exercise of the right overflowed, causing damage that the employer is not in a position to stand. Having said the above, this research work will start from the approach on the origin or not of the compensation for damages in favor of the employer when the illegality of the collective suspension of work has been declared and, consequently, the question about the scope on the matter will be addressed, concluding that, as it is characteristic of labor law, it must be known to the ordinary jurisdiction in its labor specialty.

description: This pilot study tested the feasibility and stress reduction effectiveness of a one-time virtual reality mindfulness module (VRMM) in individuals with mild-to-moderate traumatic brain injury (TBI). Thirty-eight participants participated in a pilot study utilizing a mixed methods convergent parallel design. Pretest and posttest stress levels were collected; participants engaged in a brief 4-question qualitative interview. Mann Whitney U and Wilcoxon Signed Rank Tests were used. Qualitative analysis utilized grounded theory. Post-VRMM, two-thirds (24) of participants had a statistically significant decrease in stress levels. A key qualitative finding indicated that participants found the immersiveness and realism of the VR environments helpful in compensating for cognitive deficits resulting from TBI. There were no adverse side effects reported, indicating that well-designed VRMMs that minimize motion-induced adverse effects are well tolerated in persons with TBI. A guided mindfulness activity in a VR environment was well tolerated, and participants overall found VRMM effective in reducing stress levels. VR-based environments have potential to harness guided mindfulness practice and may support persons with TBI to enhance concentration. Further application of this technology in TBI rehabilitation is promising and warrants future research to explore the benefit of VR in improving rehabilitation outcomes.
The influence of oil price shocks on the Chilean, Colombian, and Brazilian macroeconomies
Creators: name: Do Couto, David
Publisher: name: My University
Year: 2021

description: This paper uses structural VAR models to analyze the influence of an unexpected increase in oil prices on the Chilean, Colombian, and Brazilian macroeconomies, with a focus on real gross domestic product and inflation rates. A pre-determined, positive shock to oil prices is followed by real economic contractions in the Chilean and Colombian economies. On the other hand, the Brazilian real economy remains unaffected over its fullsample and in its recent years as a net oil exporter, although it experiences recessionary effects during its years as a net oil importer. Chilean and Colombian core inflation and Brazilian headline inflation all increase. All responses occur in the short run only and are robust to changes in specification.

description: We generalize our earlier work on the symplectic/Hamiltonian formulation of the dynamics of the Gaussian wave packet to non-Gaussian semiclassical wave packets. We find the symplectic forms and asymptotic expansions of the Hamiltonians associated with these semiclassical wave packets, and obtain Hamiltonian systems governing their dynamics. Numerical experiments demonstrate that the dynamics give a very good approximation to the short-time dynamics of the expectation values computed by a method based on Egorov's Theorem or the Initial Value Representation.

description: Exposures of the Earth’s crust-mantle transition are scarce, thus, limiting our knowledge about the formation of subcontinental underplate cumulates, and their significance for metal storage and migration. Here, we investigated chalcophile metals to track sulfide crystallization within the Contact Series, an <150-m-thick pyroxenite-gabbronorite sequence, formed by mantle-derived melts, highlighting the boundary between the Balmuccia mantle peridotite and gabbronoritic Mafic Complex of the Ivrea-Verbano Zone. Within the Contact Series, numerous sulfides crystallized in response to the differentiation of mantle-derived underplated melts. Such sulfide-controlled metal differentiation resulted in anomalous Cu contents (up to ~380 ppm), compared to reference mantle (~19 ppm) and crustal samples (~1 ppm). We propose that the assimilation of continental crust material is a critical mechanism driving sulfide segregation and sulfide-controlled metal storage. Our results evidence that sulfides are trapped in the underplated mafic-ultramafic cumulates and that their enrichment in Cu may provide essential implications for crustal metallogeny.

Optimization of the beam crossing angle at the ILC for e+e- and gamma-gamma collisions

description: At this time, the design of the International Linear Collider (ILC) is optimized for e+e- collisions; the photon collider (gamma-gamma and gamma-electron) is considered as an option. Unexpected discoveries, such as the diphoton excess F(750 GeV) seen at the LHC, could strongly motivate the construction of a photon collider. In order to enable the gamma-gamma collision option, the ILC design should be compatible with it from the very beginning. In this paper, we discuss the problem of the beam crossing angle. In the ILC technical design, this angle is 14 mrad, which is just enough to provide enough space for the final quadrupoles and outgoing beams. For gamma-gamma collisions, the crossing angle must be larger because the low-energy electrons that result from multiple Compton scattering get large disruption angles in collisions with the opposing electron beam and some deflection in the solenoidal detector field. For a 2E=500 GeV collider, the required crossing angle is about 25 mrad. In this paper, we consider the factors that determine the crossing angle as well as its minimum permissible value that does not yet cause a considerable reduction of the gamma-gamma luminosity. It is shown that the best solution is to increase the laser wavelength from the current 1 \mum (which is optimal for 2E=500 GeV) to 2 \mum as this makes possible achieving high gamma-gamma luminosities at a crossing angle of 20 mrad, which is also quite comfortable for e+e- collisions, does not cause any degradation of the e+e- luminosity and opens the possibility for a more energetic future collider in the same tunnel (e.g., CLIC). Moreover, the 2 \mum wavelength is optimal for a 2E = 1 TeV collider, e.g., a possible ILC energy upgrade. Please consider this paper an appeal to increase the ILC crossing angle from 14 to 20 mrad.

description: Friction behaviour is an important characteristic of dynamic seals. Surface texturing is an effective method to control the friction level without the need to change materials or lubricants. However, it is difficult to put the manual prediction of optimal friction reducing textures as a function of operating conditions into practice. Therefore, in this paper, we use machine learning techniques for the prediction of optimal texture parameters for friction optimisation. The application of pneumatic piston seals serves as an illustrative example to demonstrate the machine learning method and results. The analyses of this work are based on experimentally determined data of surface texture parameters, defined by the dimple diameter, distance, and depth. Furthermore friction data between the seal and the pneumatic cylinder are measured in different friction regimes from boundary over mixed up to hydrodynamic lubrication. A particular innovation of this work is the definition of a generalised method that guides the entire machine learning process from raw data acquisition to model prediction, without committing to only a few learning algorithms. A large number of 26 regression learning algorithms are used to build machine learning models through supervised learning to evaluate the suitability of different models in the specific application context. In order to select the best model, mathematical metrics and tribological relationships, like Stribeck curves, are applied and compared with each other. The resulting model is utilised in the subsequent friction optimisation step, in which optimal surface texture parameter combinations with the lowest friction coefficients are predicted over a defined interval of relative velocities. Finally, the friction behaviour is evaluated in the context of the model and optimal value combinations of the surface texture parameters are identified for different lubrication conditions.

description: The joint detection of gravitational waves and electromagnetic radiation from the binary neutron star (BNS) merger GW170817 has provided unprecedented insight into a wide range of physical processes: heavy element synthesis via the $r$-process; the production of relativistic ejecta; the equation of state of neutron stars and the nature of the merger remnant; the binary coalescence timescale; and a measurement of the Hubble constant via the "standard siren" technique. In detail, all of these results depend on the distance to the host galaxy of the merger event, NGC4993. In this paper we measure the surface brightness fluctuation (SBF) distance to NGC4993 in the F110W and F160W passbands of the Wide Field Camera 3 Infrared Channel on the Hubble Space Telescope (HST). For the preferred F110W passband we derive a distance modulus of $m{-}M=33.05\pm0.08\pm0.10$ mag, or a linear distance $d=40.7\pm1.4\pm1.9$ Mpc (random and systematic errors, respectively); a virtually identical result is obtained from the F160W data. This is the most precise distance to NGC4993 available to date. Combining our distance measurement with the corrected recession velocity of NGC4993 implies a Hubble constant $H_0=71.9\pm 7.1~km~s^{-1}~Mpc^{-1}$. A comparison of our result to the GW-inferred value of $H_0$ indicates a binary orbital inclination of $i\,{\gtrsim}\,137~°$. The SBF technique can be applied to early-type host galaxies of BNS mergers to ${\sim\,}100$ Mpc with HST and possibly as far as ${\sim\,}300$ Mpc with the James Webb Space Telescope, thereby helping to break the inherent distance-inclination degeneracy of the GW signals at distances where many future BNS mergers are likely to be detected.

Conditional Cash Transfers and Shocks: Evidence from the Philippines
Creators: name: Flaminiano, John Paul
Publisher: name: My University
Year: 2019

description: We evaluate the impact of the Pantawid Pamilyang Pilipino Program, a conditional cash transfer (CCT) program in the Philippines, on household welfare in the presence of various shocks to household members such as death, illness, loss of employment, business failure, and natural or man-made disasters. Using a regression discontinuity design (RDD), we estimate whether the CCT program induces its beneficiary households to adjust their spending patterns differently from nonbeneficiaries when exposed to shocks. Our estimates show that on average, CCT beneficiary households may allot anywhere from 1.2 to 2 percentage points smaller share of their household income on alcohol and tobacco, relative to non-CCT beneficiary households when exposed to shocks. We find no evidence that CCT beneficiary households adjust their spending on education when exposed to shocks.

description: This is a numerical study of thermoelectric properties of ballistic bilayer graphene in the presence of trigonal warping term in the effective Hamiltonian. We find, in the mesoscopic samples of the length $L>10\,μ$m at sub-Kelvin temperatures, that both the Seebeck coefficient and the Lorentz number show anomalies (the additional maximum and minimum, respectively) when the electrochemical potential is close to the Lifshitz energy, which can be attributed to the presence of the van Hove singularity in a bulk density of states. At higher temperatures the anomalies vanish, but measurable quantities characterizing remaining maximum of the Seebeck coefficient still unveil the presence of massless Dirac fermions and make it possible to determine the trigonal warping strength. Behavior of the thermoelectric figure of merit ($ZT$) is also discussed.

description: This investigation sought to examine the perceptions of individuals with mild, moderate, and severe traumatic brain injury (TBIs) toward healthcare providers across rehabilitation contexts (acute, rehabilitation, and chronic). The mCARE-TBI survey was distributed via Qualtrics throughout the US and Canada. Sixty-four survey responses met criteria for analysis. Participants were ≥18 years old, one-year post onset, reported no unrelated neurological deficits prior to the single TBI, and reported no prior diagnosed psychiatric disorders. The mCARE was the primary outcome measure. Comparisons were made between provider ratings on each question. Significant differences were found between chronic-phase care, compared to acute care and rehabilitation. Group differences were found in transitioning home after discharge and in between each therapy discipline and both nurses and doctors, as well as for really listening and pairwise differences between therapy disciplines and both nurses and doctors. Group effects were found for showing compassion and care and being positive. All disciplines need to improve communication, and transition care/discharge planning. Dismissal of ongoing impairments continues to be an area of perceived concern with doctors in particular. Communication training is needed, particularly for nurses and doctors.

description: En este trabajo de investigación se estudia un paradigma propio de la disciplina específica del derecho penal que es el resultado de la humanización de esa rama del derecho y que ha reformado la política criminal del Estado, cuando menos, en dos sentidos: primero consiste en incorporar la idea de un derecho penal mínimo; segundo, que es el que interesa en este trabajo, consiste en incorporar criterios de resocialización de las personas que han sido objeto de una pena privativa de la libertad en la cultura jurídica externa. El lector de este trabajo podrá corroborar que el enfoque de cultura jurídica propicia un análisis crítico que pone en evidencia que el orden social colombiano ha prolongado la segregación de los seres humanos sancionados con pena privativa de la libertad, mediante la discriminación social que se hace efectiva cuando esas personas condenadas recobran su libertad y el goce integral de sus derechos. Por otro lado, el enfoque de cultura jurídica es coherente con la propuesta de la autora del presente trabajo de una política pública criminal renovada y dirigida a transformar ese comportamiento social negativo mediante procesos educativos fundados en valores humanos de convivencia pacífica, resiliencia y perdón.
description: In this research work, a paradigm of the specific discipline of criminal law is studied, which is the result of the humanization of this branch of law and which has reformed the State's criminal policy, at least in two ways: first, it consists of incorporating the idea of a minimum criminal law; second, which is the one of interest in this work, consists of incorporating criteria for the resocialization of people who have been subject to a custodial sentence in the external legal culture. The reader of this work will be able to corroborate that the legal culture approach fosters a critical analysis that shows that the Colombian social order has prolonged the segregation of human beings sentenced to imprisonment, through social discrimination that becomes effective. when those sentenced people recover their freedom and full enjoyment of their rights. On the other hand, the legal culture approach is consistent with the author's proposal for a renewed criminal public policy aimed at transforming this negative social behavior through educational processes based on human values of peaceful coexistence, resilience and forgiveness.

description: It is shown that the families of generalized matrix ensembles recently considered which give rise to an orthogonal invariant stable Lévy ensemble can be generated by the simple procedure of dividing Gaussian matrices by a random variable. The nonergodicity of this kind of disordered ensembles is investigated. It is shown that the same procedure applied to random graphs gives rise to a family that interpolates between the Erdös-Renyi and the scale free models.

description: The temperatures in large parts of Europe have been record high during the meteorological autumn of 2006. Compared to 1961-1990, the 2m temperature was more than three degrees Celsius above normal from the North side of the Alps to southern Norway. This made it by far the warmest autumn on record in the United Kingdom, Belgium, the Netherlands, Denmark, Germany and Switzerland, with the records in Central England going back to 1659, in the Netherlands to 1706 and in Denmark to 1768. Assuming that the mean of the temperature distribution changes proportional to the global mean temperature, but the shape remains the same includes to first order the effects of global warming. Even under this assumption the autumn temperatures were very unusual, with estimates of the return time of 200 to 2000 years in this region. The lower bound of the 95% confidence interval is more than 100 to 300 years. Climate models that simulate the current atmospheric circulation well underestimate the observed mean rise in autumn temperatures. They do not simulate a change in the shape of the distribution that would increase the probability of warm events under global warming. This implies that the warm autumn 2006 either was a very rare coincidence, or the local temperature rise is much stronger than modelled, or non-linear physics that is missing from these models increases the probability of warm extremes.

description: Comprendiendo que la globalización, los cambios generacionales y la tecnología invitan a las diferentes industrias y sectores de esparcimiento a generar cambios para garantizar su sostenibilidad y adaptación hacia los nuevos consumidores, Por eso es importante tener en cuenta qué es lo que buscan los nuevos consumidores como lo son los Millennials (nacidos entre 1981 - 1996) y Centennials (nacidos entre 1997 - 2012) y la influencia según sus características en la compra de Tiempo Compartido. La comercialización de tiempo compartido en Colombia, actualmente se caracteriza, por ser repetitiva, poco innovadora y que no cumple las necesidades de los nuevos consumidores. El Hotel Zuana Beach Resort, en Santa Marta, debe repensar el producto de tiempo compartido, para que sea más atractivo a la nueva generación de consumidores, que en últimas son los que sienten mayor interés por viajar y más disponibilidad de tiempo tienen para hacerlo, ya sea por negocio o por diversión, según las cifras abordadas. En este orden de ideas se plantea la necesidad de identificar las características de estos nuevos consumidores en la compra del producto de tiempo compartido.

Timeshare in Colombia is currently characterized by being repetitive, not very innovative and does not meet the needs of new consumers. Hotel Zuana Beach Resort, in Santa Marta, must rethink the timeshare product, to make it more attractive to the new generation of consumers, who ultimately are the ones who feel the greatest interest in traveling and have the most time available to do so. either for business or for fun. In this order of ideas, the need to identify the characteristics of these new consumers in the purchase of the timeshare product arises.

description: The hydrodynamic Drude model (HDM) has been successful in describing the optical properties of metallic nanostructures, but for semiconductors where several different kinds of charge carriers are present, an extended theory is required. We present a two-fluid hydrodynamic model for semiconductors containing electrons and holes (from thermal or external excitation) or light and heavy holes (in $p$-doped materials). The two-fluid model predicts the existence of two longitudinal modes, an acoustic and an optical, whereas only an optical mode is present in the HDM. By extending nonlocal Mie theory to two plasmas, we are able to simulate the optical properties of two-fluid nanospheres and predict that the acoustic mode gives rise to peaks in the extinction spectra that are absent in the HDM.

description: Bien qu’un grand nombre de chercheurs s’intéressent à la déficience intellectuelle (DI) et à l’autisme, ou ce qui est désigné comme « trouble du spectre de l’autisme » (TSA) dans les services sociaux, peu de recherches mettent en lumière la manière dont les services sont offerts dans les centres de réadaptation en déficience intellectuelle et en troubles envahissants du développement (CRDITED). Ce mémoire s’est donné pour tâche d’analyser l’offre de services en DI-TSA et de répertorier les avantages et inconvénients d’offrir des services combinés pour ces populations. À cette fin, une recension des écrits sur le handicap, l’autisme et la DI a été effectuée et ces écrits ont faits l’objet d’une analyse thématique. Constitué de quatre chapitres, ce mémoire montre que les services combinés comportent à la fois des avantages et des inconvénients pour les personnes usagères. Le premier chapitre présente les réalités des personnes autistes ou neurodivergentes et des personnes présentant une DI. Le deuxième chapitre analyse les services offerts par les CRDITED. Le troisième aborde les avantages et les inconvénients d’offrir des services combinés. Le dernier chapitre propose certaines recommandations pour améliorer les pratiques en DI-TSA. Mots clés : handicap, déficience intellectuelle, autisme, neurodivergence, offre de services, services combinés, services séparés, besoins, soutien.

description: El propósito de la presente investigación es analizar, desde un punto de vista histórico y jurídico, la manera en que se fueron construyendo los enfoques teóricos de la minería como actividad económica de extracción para la generación de riqueza en clave comparativa con la protección ambiental respecto de la responsabilidad extracontractual del Estado en este ámbito. De manera puntual se pretende determinar el alcance de la responsabilidad extracontractual del Estado colombiano frente a los efectos nocivos ecológicos generados por la explotación minera ilegal en el Río Dagua del Valle del Cauca teniendo en cuenta que la explotación minera como una actividad económica puede generar deterioro, destrucción o modificación al medio natural en sus elementos físico-naturales y biológicos. En este caso, es preciso identificar las diversas formas en las cuales se puede tutelar el río, determinar sobre quiénes recae la responsabilidad de hacerlo, y establecer los parámetros de exigibilidad en cuanto a la obligación que tiene el Estado de responder –por omisión o acción- de los daños ecológicos que se han generado al Río Dagua del Valle del Cauca por ejercicio de la explotación minera ilegal en esa zona.
The corruption of Legitimacy: How American and British Counterinsurgency Strategies Ignore Jus ad Bellum as the Foundation of Legitimate War
Creators: name: Tokarczyk, Andre
Publisher: name: My University

description: The United States Army Field Manual FM 3-24 Insurgencies and Countering Insurgencies (FM 3-24) and the British Army Field Manual Volume 1 Part 10 Countering Insurgency (AFM 1-10) are the most comprehensive representations of modern counterinsurgency thinking. Yet they both contain several fundamental flaws that diminish their usefulness as effective strategic frameworks. American and British counterinsurgency strategies lack any significant discussion of the principles of just war theory, as a result they fundamentally misunderstand legitimacy in the context of war. FM 3-24 and AFM 1-10 forget that legitimacy is not a by-product of jus in bello alone, instead it is a result of satisfying all of criteria of jus ad bellum and of behaving justly in war (i.e. adhering to jus in bello). This paper argues that modern counterinsurgency frameworks would be better served if they incorporated the principles of jus ad bellum more rigorously. Incorporating all aspects of just war theory into counterinsurgency thinking would lead to better strategies that discourage overly aggressive interventions that cause unnecessary harm to soldiers and civilians alike.

description: It has long been recognized that the finite speed of light can affect the observed time of an event. For example, as a source moves radially toward or away from an observer, the path length and therefore the light travel time to the observer decreases or increases, causing the event to appear earlier or later than otherwise expected, respectively. This light travel time effect (LTTE) has been applied to transits and eclipses for a variety of purposes, including studies of eclipse timing variations (ETVs) and transit timing variations (TTVs) that reveal the presence of additional bodies in the system. Here we highlight another non-relativistic effect on eclipse or transit times arising from the finite speed of light---caused by an asymmetry in the transverse velocity of the two eclipsing objects, relative to the observer. This asymmetry can be due to a non-unity mass ratio or to the presence of external barycentric motion. Although usually constant, this barycentric and asymmetric transverse velocities (BATV) effect can vary between sequential eclipses if either the path length between the two objects or the barycentric transverse velocity varies in time. We discuss this BATV effect and estimate its magnitude for both time-dependent and time-independent cases. For the time-dependent cases, we consider binaries that experience a change in orbital inclination, eccentric systems with and without apsidal motion, and hierarchical triple systems. We also consider the time-independent case which, by affecting the primary and secondary eclipses differently, can influence the inferred system parameters, such as the orbital eccentricity.
