description: La riqueza que se genera en la zona minera de esmeralda no genera condiciones de vida digna para los mineros tradicionales y sus habitantes en general, pues según cifras de indicadores de NBI de 2018, los municipios de Muzo, Quípama y San Pablo de Borbur presentan el 23,6%, el 40,46% y el 22,55% respectivamente y el porcentaje de personas en situación de miseria de Muzo es del 4,53%, el de Quípama es de 9,25% y de San pablo de Bourbur es de 4,12% (DANE, 2020). Frente a este panorama, surge la necesidad de encontrar estrategias que puedan aportar a mejorar la situación actual de estos municipios pensando en la reconversión laboral como alternativa, por lo que la presente investigación parte de la pregunta ¿Cuáles son los elementos necesarios para desarrollar una estrategia de reconversión laboral que contribuya al mejoramiento de la calidad de vida de los mineros tradicionales de la zona esmeralderas del Occidente de Boyacá? En este sentido, se desarrolla una investigación cualitativa desde el paradigma de la complejidad y se aborda la epistemología del construccionismo social.
description: The wealth generated in the emerald mining area does not generate decent living conditions for traditional miners and their inhabitants in general, as according to UBN indicator figures from 2018, the municipalities of Muzo, Quípama and San Pablo de Borbur have 23.6%, 40.46% and 22.55% respectively and the percentage of people in a situation of misery of Muzo is 4.53%, that of Quípama is 9.25% and of San pablo de Bourbur is 4.12% (DANE, 2020). Faced with this panorama, the need arises to find strategies that can contribute to improving the current situation of these municipalities thinking about labor reconversion as an alternative, so this research starts from the question ¿What are the elements necessary to develop a labor reconversion strategy that contributes to the improvement of the quality of life of the traditional miners of the emerald zone of Western Boyacá? In this sense, a qualitative research is developed from the paradigm of complexity and the epistemology of social constructionism is addressed.

description: We develop the M-brane actions proposed in arXiv:1607.04265 by using $η$-symbols determined in arXiv:1708.06342. Introducing $η$-forms that are defined with the $η$-symbols, we present U-duality-covariant M-brane actions which describe the known brane worldvolume theories for M$p$-branes with $p=0,2,5$. We show that the self-duality relation known in the double sigma model is naturally generalized to M-branes. In particular, for an M5-brane, the self-duality relation is nontrivially realized, where the Hodge star operator is defined with the familiar M5-brane metric while the $η$-form contains the self-dual 3-form field strength. The action for a Kaluza-Klein monopole is also partially reproduced. Moreover, we explain how to treat type IIB branes in our general formalism. As a demonstration, we reproduce the known action for a $(p,q)$-string.

description: The interplay among environment, demography, and host-parasite interactions is a challenging frontier. In the ocean, fundamental changes are occurring due to anthropogenic pressures, including increased disease outbreaks on coral reefs. These outbreaks include multiple parasites, calling into question how host immunity functions in this complex milieu. Our work investigates the interplay of factors influencing co-infection in the Caribbean sea fan octocoral, Gorgonia ventalina, using metrics of the innate immune response: cellular immunity and expression of candidate immune genes. We used existing copepod infections and live pathogen inoculation with the Aspergillus sydowii fungus, detecting increased expression of the immune recognition gene Tachylectin 5A (T5A) in response to both parasites. Cellular immunity increased by 8.16% in copepod infections compared to controls and single Aspergillus infections. We also detected activation of cellular immunity in reef populations, with a 13.6% increase during copepod infections. Cellular immunity was similar in the field and in the lab, increasing with copepod infections and not the fungus. Amoebocyte density and the expression of T5A and a matrix metalloproteinase (MMP) gene were also positively correlated across all treatments and colonies, irrespective of parasitic infection. We then assessed the scaling of immune metrics to population-level disease patterns and found random co-occurrence of copepods and fungus across 15 reefs in Puerto Rico. The results suggest immune activation by parasites may not alter parasite co-occurrence if factors other than immunity prevail in structuring parasite infection. We assessed non-immune factors in the field and found that sea fan colony size predicted infection by the copepod parasite. Moreover, the effect of infection on immunity was small relative to that of site differences and live coral cover, and similar to the effect of reproductive status. While additional immune data would shed light on the extent of this pattern, ecological factors may play a larger role than immunity in controlling parasite patterns in the wild. Parsing the effects of immunity and ecological factors in octocoral co-infection shows how disease depends on more than one host and one parasite and explores the application of co-infection research to a colonial marine organism.

description: Many African nations continue to grapple with persistently high under-five child mortality rates, particularly those situated in the Sub-Saharan region, including South Africa. A multitude of socio-economic factors are identified as key contributors to the elevated under-five child mortality in numerous African nations. This research endeavors to investigate various factors believed to be associated with child mortality by employing advanced statistical models. This study utilizes child-level survival data from South Africa, characterized by left truncation and right censoring, to fit a Cox proportional hazards model under the assumption of working independence. Additionally, a shared frailty model is applied, clustering children based on their mothers. Comparative analysis is performed between the results obtained from the shared frailty model and the Cox proportional hazards model under the assumption of working independence. Within the scope of this analysis, several factors stand out as significant contributors to under-five child mortality in the study area, including gender, birth province, birth year, birth order, and twin status. Notably, the shared frailty model demonstrates superior performance in modeling the dataset, as evidenced by a lower likelihood cross-validation score compared to the Cox proportional hazards model assuming independence. This improvement can be attributed to the shared frailty model?s ability to account for heterogeneity among mothers and the inherent association between siblings born to the same mother, ultimately enhancing the quality of the study?s conclusions.

description: Globally, the coexistence of metabolic syndrome (MetS) and HIV has become an important public health problem, putting coronavirus disease 19 (COVID-19) hospitalized patients at risk for severe manifestations and higher mortality. A retrospective cross-sectional analysis was conducted to identify factors and determine their relationships with hospitalization outcomes for COVID-19 patients using secondary data from the Department of Health in Limpopo Province, South Africa. The study included 15,151 patient clinical records of laboratory-confirmed COVID-19 cases. Data on MetS was extracted in the form of a cluster of metabolic factors. These included abdominal obesity, high blood pressure, and impaired fasting glucose captured on an information sheet. Spatial distribution of mortality among patients was observed; overall (21?33%), hypertension (32?43%), diabetes (34?47%), and HIV (31?45%). A multinomial logistic regression model was applied to identify factors and determine their relationships with hospitalization outcomes for COVID-19 patients. Mortality among COVID-19 patients was associated with being older (≥50+ years), male, and HIV positive. Having hypertension and diabetes reduced the duration from admission to death. Being transferred from a primary health facility (PHC) to a referral hospital among COVID-19 patients was associated with ventilation and less chance of being transferred to another health facility when having HIV plus MetS. Patients with MetS had a higher mortality rate within seven days of hospitalization, followed by those with obesity as an individual component. MetS and its components such as hypertension, diabetes, and obesity should be considered a composite predictor of COVID-19 fatal outcomes, mostly, increased risk of mortality. The study increases our understanding of the common contributing variables to severe manifestations and a greater mortality risk among COVID-19 hospitalized patients by investigating the influence of MetS, its components, and HIV coexistence. Prevention remains the mainstay for both communicable and non-communicable diseases. The findings underscore the need for improvement of critical care resources across South Africa.

Gravitational wave emission from core-collapse supernovae

description: Invited talk Accademia Nazionale dei Lincei (October 24th and 25th, 2024) on the prospects of probing the central engine of core-collapse supernovae in the Local Universe. The most energetic events may be powered by Kerr black holes. Based on the first detection GW170817B of a black hole central engine at 5.5σ significance, we project a horizon distance up to 160 Mpc. This prospect is in striking agreement with a prescient earlier estimate of 150 Mpc (Cutler & Thorne 2002). Subject to event rates and finite duty cycles of the LIGO detectors H1 and L1, we expect, conservatively, the potential of a few detections per decade from energetic CC-SNe in the Local Universe.

description: We show that in the weak field limit the light deflection alone cannot distinguish between different $R + F[g(\square)R]$ models of gravity, where $F$ and $g$ are arbitrary functions. This does not imply, however, that in all these theories an observer will see the same deflection angle. Owed to the need to calibrate the Newton constant, the deflection angle may be model-dependent after all necessary types of measurements are taken into account.

description: Providers of dynamicWeb applications are currently unable to accommodate heavy usage without significant investment in infrastructure and in-house management capability. Our goal is to develop technology to enable a third party to offer scalability as a subscription service with “per-click” pricing to application providers. To this end we have developed a prototype proxy caching system able to scale delivery of dynamic Web content to a large number of users. In this paper we report initial positive results obtained from our prototype that point to the feasibility of our goal. We also report the shortcomings of our current prototype, the chief one being the lack of a scalable method of managing data consistency. We then present our initial work on a novel approach to scalable consistency management. Our approach is based on a fully distributed mechanism that does not require content providers to assist in managing the consistency of remotely cached data. Finally, we describe our ongoing efforts to characterize the inherent tradeoff between scalability and data secrecy, a crucial issue in environments shared by multiple organizations.

description: The reduction reactions and densification of nanochains assembled from γ-Fe₂O₃ nanoparticles were investigated using in situ transmission electron microscopy (TEM). Morphological changes and reduction of the metal oxide nanochains were observed during in situ TEM annealing through simultaneous imaging and quantitative analysis of the near-edge fine structures of Fe L₂,₃ absorption edges acquired by spatially resolved electron energy loss spectroscopy. A change in the oxidation states during annealing of the iron oxide nanochains was observed with phase transformations due to continuous reduction from Fe₂O₃ over Fe₃O ₄, FeO to metallic Fe. Phase transitions during the in situ heating experiments were accompanied with morphological changes in the nanochains, specifically rough-to-smooth surface transitions below 500 °C, neck formation between adjacent particles around 500 °C, and subsequent neck growth. At higher temperatures, coalescence of FeO particles was observed, representing densification.

description: We elaborate a method for the creation of two- and one-dimensional (2D and 1D) self-trapped modes in binary spin-orbit (SO)-coupled Bose-Einstein condensates (BECs) with the contact repulsive interaction, whose local strength grows fast enough from the center to periphery. In particular, an exact semi-vortex (SV) solution is found for the anti-Gaussian radial-modulation profile. The exact modes are included in the numerically produced family of SV solitons. Other families, in the form of mixed modes(MMs), as well as excited state of SVs and MMs, are produced too. While the excited states are unstable in all previously studied models, they are partially stable in the present one. In the 1D version of the system, exact solutions for the counterpart of the SVs, namely, \textit{semi-dipole} solitons, are found too. Families of semi-dipoles, as well as the 1D version of MMs, are produced numerically.

description: We describe the design and fabrication of on-chip broadband load calibrators for element-by- element and full circuit characterization of transition-edge sensor (TES) bolometers for cosmic microwave background (CMB) polarimetry. Fabricated in a 4 X 4 grid on a 100 mm silicon wafer, the chips allow systematic testing of individual detector circuit elements without the need for an external blackbody source. This in-situ testing approach provides rapid and efficient characterization of various pixel designs in order to optimize the optical efficiency and control of systematic effects of the detectors. In this work, we demonstrate the on-chip calibrators on the Cosmology Large Angular Scale Surveyor (CLASS) W-band pixels. In particular, we investigate the loss on microstrip transmission lines and measure the performance of various designs of TESs, magic-tees, via-less crossovers, and signal terminations. We also test a filter-bank spectrometer with eight resonators spanning 80 - 105 GHz to characterize the spectral response of circuit elements across the detector bandwidth.

description: Abstract: "Parametric representations used for symbolic simulation of circuits usually use BDDs. After a few steps of symbolic simulation, state set representation is converted from one parametric representation to another smaller representation, in a process called reparameterization. For large circuits, the reparameterization step often results in a blowup of BDDs and is expensive due to a large number of quantifications of input variables involved. Efficient SAT solvers have been applied successfully for many verification problems. This paper presents a novel SAT-based reparameterization algorithm that is largely immune to the large number of input variables that need to be quantified. We show experimental results on large industrial circuits and compare our new algorithm to both SAT-based Bounded Model Checking and BDD-based symbolic simulation. We were able to achieve on average 3x improvement in time and space over BMC and able to complete many examples that BDD-based approach could not even finish."
Kinematic alpha effect in isotropic turbulence simulations

description: Using numerical simulations at moderate magnetic Reynolds numbers up to 220 it is shown that in the kinematic regime, isotropic helical turbulence leads to an alpha effect and a turbulent diffusivity whose values are independent of the magnetic Reynolds number, $\Rm$, provided $\Rm$ exceeds unity. These turbulent coefficients are also consistent with expectations from the first order smoothing approximation. For small values of $\Rm$, alpha and turbulent diffusivity are proportional to $\Rm$. Over finite time intervals meaningful values of alpha and turbulent diffusivity can be obtained even when there is small-scale dynamo action that produces strong magnetic fluctuations. This suggests that small-scale dynamo-generated fields do not make a correlated contribution to the mean electromotive force.

description: We examine the Backus average of a stack of isotropic layers overlying an isotropic halfspace to examine its applicability for the quasi-Rayleigh and Love wave dispersion curves, both of which apply to the same model. We compare these curves to values obtained for the stack of discrete layers using the propagator matrix. The Backus average is applicable only for thin layers or low frequencies. This is true for both weakly inhomogeneous layers resulting in a weakly anisotropic medium and strongly inhomogeneous alternating layers resulting in a strongly anisotropic medium. We also compare the strongly anisotropic and weakly anisotropic media, given by the Backus averages, to results obtained by the isotropic Voigt averages of these media. As expected, we find only a small difference between these results for weak anisotropy and a large difference for strong anisotropy. We perform the Backus average for a stack of alternating transversely isotropic layers that is strongly inhomogeneous to evaluate the dispersion curves for the resulting medium. We compare these curves to values obtained using a propagator matrix for that stack of discrete layers. Again, there is a good match only for thin layers or low frequencies. Finally, we perform the Backus average for a stack of nonalternating transversely isotropic layers that is strongly inhomogeneous, and evaluate the quasi-Rayleigh wave dispersion curves for the resulting transversely isotropic medium. We compare these curves to values obtained using the propagator matrix for the stack of discrete layers. In this case, the Backus average performs less well, but---for the fundamental mode---remains adequate for low frequencies or thin layers.

description: We report the effect of the cosmological constant and the internal energy density of a cosmic string on the deflection angle of light in the spacetime of a rotating cosmic string with internal structure. We first revisit the deflection angle by a rotating cosmic string and then provide a generalization using the geodesic equations and the Gauss-Bonnet Theorem. We show there is an agreement between the two methods when employing higher order terms of the linear mass density of the cosmic string. By modifying the integration domain for the global conical topology, we resolve the inconsistency between these two methods previously reported in the literature. We show that the deflection angle is not affected by the rotation of the cosmic string; however, the cosmological constant $Λ$ strongly affects the deflection angle, which generalizes the well-known result.

description: The overarching goal of this 1-year SERDP SEED project was to develop and test a range of functionalized polymeric membranes for use in equilibrium passive sampling of PFAS compounds. The following objectives were addressed in this project: 1) develop novel polymeric thin films for equilibrium passive sampling that will be either solid or liquid sorbents embedded in a thin polymer sheet; 2) perform equilibrium partitioning studies with PFAS compounds covering a range of properties and interpret isotherm data based on sorption models; 3) test equilibrium reversibility for the top two choices of polymers and assess the use of performance reference compounds to quantify the extent of equilibrium; 4) evaluate the mechanism of the sorption process. We demonstrate that several composite polymers can be synthesized that remain stable in the water environment and provide adequate sorption of PFAS from aqueous solution at equilibrium. Initial results presented in this report show great promise for pursuing the concept of equilibrium passive sampling for PFAS in water.

description: We present a new method for renormalisation group improvement of the effective potential of a quantum field theory with an arbitrary number of scalar fields. The method amounts to solving the renormalisation group equation for the effective potential with the boundary conditions chosen on the hypersurface where quantum corrections vanish. This hypersurface is defined through a suitable choice of a field-dependent value for the renormalisation scale. The method can be applied to any order in perturbation theory and it is a generalisation of the standard procedure valid for the one-field case. In our method, however, the choice of the renormalisation scale does not eliminate individual logarithmic terms but rather the entire loop corrections to the effective potential. It allows us to evaluate the improved effective potential for arbitrary values of the scalar fields using the tree-level potential with running coupling constants as long as they remain perturbative. This opens the possibility of studying various applications which require an analysis of multi-field effective potentials across different energy scales. In particular, the issue of stability of the scalar potential can be easily studied beyond tree level.

description: A catastrophic failure occurred on the carbon steel piping system of a steam generator after 20 years of operation. The failure occurred at a time when the system experienced a slight increase in pressure of approximately 300 psig more than its normal operating pressure, but 775 psig below the design pressure. Three failed sections at welded joints of the 2” and 3” Ø piping indicated different failure modes and suggested erosion-corrosion, material deterioration and weld imperfections all contributed to the cause of failure. Based on the analysis conducted it was also suggested that the failure involved more than one failure mechanism it included one that initiated the failure and another that eventually destroyed the parts. The long-term deterioration of the 2″Ø elbow showed the Longitudinal cracks that developed due to hoop stress allowed steam to escape into the atmosphere, then at ‘down times’ moisture from the environment penetrated the crack and assisted in the corrosion process. The weld imperfections of the 3” Ø pipeline which was also compromised by the corrosion process could not withstand the increase pressure and failed in a transverse manner thus allowing the other joints to fail in a similar manner. Methods to mitigate similar failures are discussed in terms of following established welding procedures and adopting preventative maintenance procedures.

description: The freely dissolved concentration of hydrophobic pollutants in sediment porewater (Cpw) is a critical driver for exposure to aquatic organisms, bioaccumulation, toxicity, and flux across interfaces. In this research, we compared direct porewater extraction and passive sampling for Cpw measurements of a range of PCBs and PAHs in field-collected sediments. The direct water extraction method provided accurate quantification of Cpw for low to moderately hydrophobic PCB and PAH compounds (log Kow < 6.5) that compared well with independent measurements performed using four passive sampling methods. Direct water extraction was adequate to assess narcosis toxicity of PAHs to benthic organisms that is driven by the concentrations of low to moderately hydrophobic PAHs (naphthalene to chrysene), even for a hypothetical sediment that had a tenth of the PAH concentrations of the study sediments and was assessed to be nontoxic. Prediction of PCB bioaccumulation in benthic organisms agreed within 50% for all measurement methods, but it was apparent that for less contaminated sediments, the direct water extraction method would likely have detection limit challenges, especially for the strongly hydrophobic PCBs. To address the uncertainty of the Cpw measurement of the strongly hydrophobic compounds and naphthalene, a new extrapolation approach is demonstrated that can be applicable for both direct water extraction and passive sampling methods.

description: Is gravity parity violating? Given the recent observations of gravitational waves from coalescing compact binaries, we develop a strategy to find an answer with current and future detectors. We identify the key signatures of parity violation in gravitational waves: amplitude birefringence in their propagation and a modified chirping rate in their generation. We then determine the optimal binaries to test the existence of parity violation in gravity, and prioritize the research in modeling that will be required to carry out such tests before detectors reach their design sensitivity.

description: Abstract: "Many older adults use walkers to improve their stability and safety while walking. We have developed a robotically augmented walker to reduce fall risk and confusion, and to increase walker convenience and enjoyment. Using a modified version of the CARMEN navigation software suite [11], the walker is capable of parking itself and returning to the user when signaled by remote control. The system also supports navigation in large indoor environments by providing simple directions to target locations such as a cafeteria. The walker received positive reviews during informal testing with residents of a Pennsylvania residence facility for older adults."

description: Mode-locked InAs/InGaAs quantum dot lasers emitting optical frequency combs centered at 1310 nm are promising sources for high-speed and high-capacity communication applications. We report on the stable optical pulse train generation by a monolithic passively mode-locked edge-emitting two-section quantum dot laser based on a five-stack InAs/InGaAs dots-in-a-well structure directly grown on an on-axis (001) silicon substrate by solid-source molecular beam epitaxy. Optical pulses as short as 1.7 ps at a pulse repetition rate or inter-mode beat frequency of 9.4 GHz are obtained. A minimum pulse-to-pulse timing jitter of 9 fs, corresponding to a repetition rate line width of 400 Hz, is demonstrated. The generated optical frequency combs yield exceptional low amplitude jitter performance and comb widths exceed 5.5 nm at a −3 dB criteria, containing more than 100 comb carriers.

description: This paper presents a probabilistic information retrieval framework in which the retrieval problem is formally treated as a statistical decision problem. In this framework, queries and documents are modeled using statistical language models, user preferences are modeled through loss functions, and retrieval is cast as a risk minimization problem.We discuss how this framework can unify existing retrieval models and accommodate systematic development of new retrieval models. As an example of using the framework to model nontraditional retrieval problems, we derive retrieval models for subtopic retrieval, which is concerned with retrieving documents to cover many different subtopics of a general query topic. These new models differ from traditional retrieval models in that they relax the traditional assumption of independent relevance of documents.
