description: La historia de la universidad requiere de abordajes de larga duración en los que se contemplen las diferentes etapas que la institución ha atravesado desde su origen medieval. Además, resulta necesario considerar el contexto, con una mirada analítica que oscile entre lo micro y lo macro para lograr aproximarse a lo que caracteriza a la universidad y, a su vez, a cada caso en particular. Este es el recorrido que nos propone Adrián Acosta Silva, desde la creación de las primeras tres universidades latinoamericanas: la Universidad de Santo Domingo (1538), la Universidad de San Marcos (1551) y la Universidad de México (1551), en lo que hoy son la República Dominicana, la República del Perú y los Estados Unidos Mexicanos, respectivamente.

description: We propose genetic algorithms, which are robust optimization techniques inspired by natural selection, to enhance the versatility of digital quantum simulations. In this sense, we show that genetic algorithms can be employed to increase the fidelity and optimize the resource requirements of digital quantum simulation protocols, while adapting naturally to the experimental constraints. Furthermore, this method allows us to reduce not only digital errors, but also experimental errors in quantum gates. Indeed, by adding ancillary qubits, we design a modular gate made out of imperfect gates, whose fidelity is larger than the fidelity of any of the constituent gates. Finally, we prove that the proposed modular gates are resilient against different gate errors.

description: We study, in theory and experiment, the quantum properties of correlated light fields measured with click-counting detectors providing incomplete information on the photon statistics. We establish a correlation parameter for the conditional statistics, and we derive the corresponding nonclassicality criteria for detecting conditional quantum correlations. Classical bounds for Pearson's correlation parameter are formulated that allow us, once they are violated, to determine nonclassical correlations via the joint statistics. On the one hand, we demonstrate nonclassical correlations in terms of the joint click statistics of light produced by a parametric down conversion source. On the other hand, we verify quantum correlations of a heralded, split single-photon state via the conditional click statistics together with a generalization to higher-order moments. We discuss the performance of the presented nonclassicality criteria to successfully discern joint and conditional quantum correlations. Remarkably, our results are obtained without making any assumptions on the response function, quantum efficiency, and dark-count rate of the photodetectors.

description: The quantum state of motion of a large and rotating polar molecule can lose coherence through the collisions with gas atoms. We show how the associated quantum master equation for the center of mass can be expressed in terms of the orientationally averaged differential and total scattering cross sections, for which we provide approximate analytic expressions. The master equation is then utilized to quantify collisional decoherence in a interference experiment with polar molecules.

description: Graph Neural Networks (GNNs) are widely used in graph data mining tasks. Traditional GNNs follow a message passing scheme that can effectively utilize local and structural information. However, the phenomena of over-smoothing and over-squashing limit the receptive field in message passing processes. Graph Transformers were introduced to address these issues, achieving a global receptive field but suffering from the noise of irrelevant nodes and loss of structural information. Therefore, drawing inspiration from fine-grained token-based representation learning in Natural Language Processing (NLP), we propose the Structure-aware Multi-token Graph Transformer (Tokenphormer), which generates multiple tokens to effectively capture local and structural information and explore global information at different levels of granularity. Specifically, we first introduce the walk-token generated by mixed walks consisting of four walk types to explore the graph and capture structure and contextual information flexibly. To ensure local and global information coverage, we also introduce the SGPM-token (obtained through the Self-supervised Graph Pre-train Model, SGPM) and the hop-token, extending the length and density limit of the walk-token, respectively. Finally, these expressive tokens are fed into the Transformer model to learn node representations collaboratively. Experimental results demonstrate that the capability of the proposed Tokenphormer can achieve state-of-the-art performance on node classification tasks.

description: It was recently proposed that a giant flare of the blazar PKS B1424-418 at redshift $z=1.522$ is in association with a PeV-energy neutrino event detected by IceCube. Based on this association we here suggest that the flight time difference between the PeV neutrino and gamma-ray photons from blazar flares can be used to constrain the violations of equivalence principle (EP) and the Lorentz invariance for neutrinos. From the calculated Shapiro delay due to clusters or superclusters in the nearby universe, we find that violation of the equivalence principle for neutrinos and photons is constrained to an accuracy of at least $10^{-5}$, which is two orders of magnitude tighter than the constraint placed by MeV neutrinos from supernova 1987A. Lorentz invariance violation (LIV) arises in various quantum-gravity theories, which predicts an energy-dependent velocity of propagation in vacuum for photons and neutrinos. We find that the association of the PeV neutrino with the gamma-ray outburst set limits on the energy scale of possible LIV to $> 0.01 E_{pl}$ for linear LIV models and $>6\times 10^{-8} E_{pl}$ for quadratic order LIV models, where $E_{pl}$ is the Planck energy scale. These are the most stringent constraints on neutrino LIV for subluminal neutrinos.

description: Privacy protection from surreptitious video recordings is an important societal challenge. We desire a computer vision system (e.g., a robot) that can recognize human activities and assist our daily life, yet ensure that it is not recording video that may invade our privacy. This paper presents a fundamental approach to address such contradicting objectives: human activity recognition while only using extreme low-resolution (e.g., 16x12) anonymized videos. We introduce the paradigm of inverse super resolution (ISR), the concept of learning the optimal set of image transformations to generate multiple low-resolution (LR) training videos from a single video. Our ISR learns different types of sub-pixel transformations optimized for the activity classification, allowing the classifier to best take advantage of existing high-resolution videos (e.g., YouTube videos) by creating multiple LR training videos tailored for the problem. We experimentally confirm that the paradigm of inverse super resolution is able to benefit activity recognition from extreme low-resolution videos.

description: We present the first ab initio calculations for $p$-shell hypernuclei including hyperon-nucleon-nucleon (YNN) contributions induced by a Similarity Renormalization Group transformation of the initial hyperon-nucleon interaction. The transformation including the YNN terms conserves the spectrum of the Hamiltonian while drastically improving model-space convergence of the Importance-Truncated No-Core Shell Model, allowing a precise extraction of binding and excitation energies. Results using a hyperon-nucleon interaction at leading order in chiral effective field theory for lower- to mid-$p$-shell hypernuclei show a good reproduction of experimental excitation energies while hyperon binding energies are typically overestimated. The induced YNN contributions are strongly repulsive and we show that they are related to a decoupling of the $Σ$ hyperons from the hypernuclear system, i.e., a suppression of the $Λ$-$Σ$ conversion terms in the Hamiltonian. This is linked to the so-called hyperon puzzle in neutron-star physics and provides a basic mechanism for the explanation of strong $Λ$NN three-baryon forces.

description: Carrier dynamics in monolayer MoS2 have been investigated using broadband femtosecond transient absorption spectroscopy (FTAS). A tunable pump pulse was used while a broadband probe pulse revealed ground and excited state carrier dynamics. Interestingly, for pump wavelengths both resonant and non-resonant with the A and B excitons, we observe a broad ground state bleach around 2.9 eV, with decay components similar to A and B. Associating this bleach with the band nesting region between K and Gamma in the band structure indicates significant k-space delocalization and overlap among excitonic wave functions identified as A, B, C, and D. Comparison of time dynamics for all features in resonance and non-resonance excitation is consistent with this finding.

description: I propose a novel approach to uncover business cycle reports’ priorities and relate them to economic fluctuations. To this end, I leverage quantitative business-cycle forecasts published by leading German economic research institutes since 1970 to estimate the proportions of latent topics in associated business cycle reports. I then employ a supervised approach to aggregate topics with similar themes, thus revealing the proportions of broader macroeconomic subjects. I obtain measures of forecasters’ subject priorities by extracting the subject proportions’ cyclic components. Correlating these priorities with key macroeconomic variables reveals consistent priority patterns throughout economic peaks and troughs. The forecasters prioritize inflation-related matters over recession-related considerations around peaks. This finding suggests that forecasters underestimate growth and overestimate inflation risks during contractive monetary policies, which might explain their failure to predict recessions. Around troughs, forecasters prioritize investment matters, potentially suggesting a better understanding of macroeconomic developments during those periods compared to peaks.

description: The recent maturation of hybrid quantum devices has led to significant enhancements in the functionality of a wide variety of quantum systems. In particular, harnessing mechanical resonators for manipulation and control has expanded the use of two-level systems in quantum information science and quantum sensing. In this letter, we report on a monolithic hybrid quantum device in which strain fields associated with resonant vibrations of a diamond cantilever dynamically control the optical transitions of a single nitrogen-vacancy (NV) defect center in diamond. We quantitatively characterize the strain coupling to the orbital states of the NV center, and with mechanical driving, we observe NV-strain couplings exceeding 10 GHz. Furthermore, we use this strain-mediated coupling to match the frequency and polarization dependence of the zero-phonon lines of two spatially separated and initially distinguishable NV centers. The experiments demonstrated here mark an important step toward engineering a quantum device capable of realizing and probing the dynamics of non-classical states of mechanical resonators, spin-systems, and photons.

Improving the screening process for obstructive sleep apnea in the primary care setting: a quality improvement project
Creators: name: Soni, Sarah J.
Publisher: name: No Publisher Supplied
Year: 2022

description: Background and purpose: There is a high prevalence of obstructive sleep apnea (OSA) in the primary care setting that is mainly underdiagnosed and under-reported in 75%-80% of the population. If untreated, OSA has implications for long-term cardiovascular, cerebrovascular, and metabolic health detriments. This quality improvement project intended to address the question: in the primary care setting, will the routine use of the STOP-Bang Questionnaire for asymptomatic adult patients with predictive risk factors such as obesity and/or hypertension improve the screening of OSA and facilitate referrals and diagnostic testing in comparison to no routine screening intervention in a three month timeframe? Methodology: The STOP-Bang Questionnaire, a validated screening tool for OSA, was implemented in a primary care practice to measure levels of low, intermediate, or high risk for OSA among asymptomatic. Results: The findings of this quality improvement project support an increase in referral rates, confirmatory testing, and initiation of treatment in asymptomatic obese or hypertensive patients and the development of substantial evidence to assist primary care providers to integrate routine screening protocols into practice. Implications for practice: The STOP-Bang Questionnaire, a validated screening tool for OSA, should be administered for all asymptomatic high-risk patients, specifically for those with obesity and/or hypertension, at least annually. The use of a screening tool evaluates a level of risk, promotes detection of disease in the primary stages, delays disease progression, and improves treatment initiatives.

description: Parton distribution functions (PDFs) play a central role in calculations for the Large Hadron Collider (LHC). To gain a deeper understanding of the emergence and interplay of constraints on the PDFs in the global QCD analyses, it is important to examine the relative significance and mutual compatibility of the experimental data sets included in the PDF fits. Toward this goal, we discuss the L$_2$ sensitivity, a convenient statistical indicator for exploring the statistical pulls of individual data sets on the best-fit PDFs and identifying tensions between competing data sets. Unlike the Lagrange Multiplier method, the L$_2$ sensitivity can be quickly computed for a range of PDFs and momentum fractions using the published Hessian error sets. We employ the L$_2$ sensitivity as a common metric to study the relative importance of data sets in the recent ATLAS, CTEQ-TEA, MSHT, and reduced PDF$_4$LHC$_{21}$ PDF analyses at NNLO and approximate N$_3$LO. We illustrate how this method can aid the users of PDFs to identify data sets that are important for a PDF at a given kinematic point, to study quark flavor composition and other detailed features of the PDFs, and to compare the data pulls on the PDFs for various perturbative orders and functional forms. We also address the feasibility of computing the sensitivities using Monte Carlo error PDFs. Together with the article, we present a companion interactive website with a large collection of plotted L$_2$ sensitivities for eight recent PDF releases.

description: Character education (CE) in secondary schools is one of the educational programs aimed to anticipate the tendency of moral perversion, as a result of moral decadence. Various forms of moral deviations that occur among high school students result in them being alienated from life because they conflict with cultural norms, school discipline, and life ethics in society. This article aims to discuss the relation of character values reinforcement and the principal’s transformational leadership strategy
 to shape student characters in a descriptive-critical manner. The objectives of this study are school strategies in optimizing the implementation of character education reinforcement. This research uses a qualitative method with a case study design. The instrument of data collection was through in-depth interviews, observation, and documentation studies. Data analysis used a
 modified analytic analysis method. Meanwhile, the data validity measurement was based on the level of credibility, transferability, dependability, and confirmability. The results emphasize the importance of shaping student character as an anticipatory step to minimize moral distortions among high school students, and the effectiveness of the principal’s transformational leadership role in optimizing the implementation of character education programs (CEP) in schools.

description: The accurate treatment of non-covalent interactions is necessary to model a wide range of applications, from molecular crystals to surface catalysts to aqueous solutions and many more. Quantum diffusion Monte Carlo (DMC) and coupled cluster theory with single, double and perturbative triple excitations [CCSD(T)] are considered two widely-trusted methods for treating non-covalent interactions. However, while they have been well-validated for small molecules, recent work has indicated that these two methods can disagree by more than 7.5 kcal/mol for larger systems. The origin of this discrepancy remains unknown. Moreover, the lack of systematic comparisons, particularly for medium-sized complexes, has made it difficult to identify which systems may be prone to such disagreements and the potential scale of these differences. In this work, we leverage the latest developments in DMC to compute interaction energies for the entire S66 dataset, containing 66 medium-sized complexes with a balanced representation of dispersion and electrostatic interactions. Comparison to previous CCSD(T) references reveals systematic trends, with DMC predicting stronger binding than CCSD(T) for electrostatic-dominated systems, while the binding becomes weaker for dispersion-dominated systems. We show that the relative strength of this discrepancy is correlated to the ratio of electrostatic and dispersion interactions, as obtained from energy decomposition analysis methods. Finally, we have pinpointed model systems: the hydrogen-bonded acetic acid dimer (ID 20) and dispersion-dominated uracil-cyclopentane dimer (ID 42), where these discrepancies are particularly prominent. These systems offer cost-effective benchmarks to guide future developments in DMC, CCSD(T) as well as the wider electronic structure theory community.

description: Recent blazar observations provide growing evidence for the presence of magnetic fields in the extragalactic regions. While a natural speculation is to associate the production to inflationary physics, it has been known that magnetogenesis solely from inflation is quite challenging. We therefore study a model in which a non-inflaton field $χ$ coupled to the electromagnetic field through its kinetic term, $-I^2(χ) F^2 /4$, continues to move after inflation until the completion of reheating. This leads to a post-inflationary amplification of the electromagnetic field. We compute all the relevant contributions to the curvature perturbation, including gravitational interactions, and impose the constraints from the CMB scalar fluctuations on the strength of magnetic fields. We, for the first time, explicitly verify both the backreaction and CMB constraints in a simple yet successful magnetogenesis scenario without invoking a dedicated low-scale inflationary model in the weak-coupling regime of the kinetic coupling model.

description: We consider the spin-orbit-induced spin Hall effect and spin swapping in diffusive superconductors. By employing the non-equilibrium Keldysh Green's function technique in the quasiclassical approximation, we derive coupled transport equations for the spectral spin and particle distributions and for the energy density in the elastic scattering regime. We compute four contributions to the spin Hall conductivity, namely, skew scattering, side-jump, anomalous velocity, and the Yafet contribution. The reduced density of states in the superconductor causes a renormalization of the spin Hall angle. We demonstrate that all four of these contributions to the spin Hall conductivity are renormalized in the same way in the superconducting state. In its simplest manifestation, spin swapping transforms a primary spin current into a secondary spin current with swapped current and polarization directions. We find that the spin-swapping coefficient is not explicitly but only implicitly affected by superconducting correlations through the renormalized diffusion coefficients. We discuss experimental consequences for measurements of the (inverse) spin Hall effect and spin swapping in four-terminal geometries. In our geometry, below the superconducting transition temperature, the spin-swapping signal is increased an order of magnitude while changes in the (inverse) spin Hall signal are moderate.

description: Purpose of the Project: The purpose of this project was to examine Post Intensive Care Syndrome (PICS) risk factors and their prevalence in the intensive care unit, increase provider awareness and recognition of PICS, implement a screening process in the critical care setting, and record referrals to a PICS Clinic. Methodology: Pre- and post-intervention retrospective chart reviews were conducted to establish risk factor prevalence and initiate referrals through screening tool implementation. Results: Of 26 patients screened, 54.54% (n=12) were male and 45.45% (n=10) were female. A total of 84.62% (n=22) qualified for a referral with 59.09% (n=13) receiving referrals according to the protocol. Of 26 patients screened, 57.69% (n=15) met the sepsis criteria, 3.84% (n=1) met the cardiac arrest criteria, 19.23% (n=5) met the previous psychological disorder criteria, 30.76% (n=8) met the 4 or more ventilator days criteria, and 42.30% (n=11) met the positive CAM-ICU criteria. In the intervention group, 15.38% (n=4) patients met zero criteria, 61.53% (n=16) met one criterion, 15.38% (n=4) met two criteria, 7.69% (n=2) met three criteria, 0 patients met four or five criteria.Implications for Practice: This project illustrates critically ill patients at risk for PICS can be identified for early referral in the acute care setting in order to promote implementation of coordinated care.

description: We investigate the Peierls-Feynman-Bogoliubov variational principle to map Hubbard models with nonlocal interactions to effective models with only local interactions. We study the renormalization of the local interaction induced by nearest-neighbor interaction and assess the quality of the effective Hubbard models in reproducing observables of the corresponding extended Hubbard models. We compare the renormalization of the local interactions as obtained from numerically exact determinant Quantum Monte Carlo to approximate but more generally applicable calculations using dual boson, dynamical mean field theory, and the random phase approximation. These more approximate approaches are crucial for any application with real materials in mind. Furthermore, we use the dual boson method to calculate observables of the extended Hubbard models directly and benchmark these against determinant Quantum Monte Carlo simulations of the effective Hubbard model.

description: Background: Understanding students’ perceptions of walking and cycling to school informs active travel interventions and policy. However, perceptions of students in rural settings are unknown, yet they are important predictors of active travel use. This study examined perceptions of walking and cycling to school among adolescents ineligible for school transport financial assistance (living ≤4.8 km of school) in rural New Zealand. Methods: Adolescents (n = 62; 53.2% female; 15.6 ± 1.5 years; five schools) resid?ing and attending a secondary school in a rural setting (population < 1,000) completed an online survey about their perceptions of walking and cycling to school (attitudes, subjective norms, perceived behavioural control/intention). Home-toschool distance was calculated using a geographic information system’s shortest network path analysis. Results: Overall, 73% walked and 11% cycled to school. Compared to cycling, adolescents reported a greater desire (57% vs 26%) and intention (74% vs 13%) to walk to school and perceived more support from friends (37% vs 30%), parents (81% vs 40%), and schools (61% vs 34%) (all p < 0.001). Adolescents also reported better physical infrastructure (presence/availability of footpaths vs cycle lanes) for walking versus cycling to school (86% vs 36%, p < 0.001). Over 95% perceived both walking and cycling to school as safe. Conclusions: Compared to cycling, walking to school was a more common and preferred transport mode with greater perceived social support and physical infrastructure. The findings suggest that supportive social and built environments appear to encourage walking to school in rural areas. Mode-specific approaches may be required to encourage cycling to school for rural adolescents.
C+/H2 Gas in Star-Forming Clouds and Galaxies

description: We present analytic theory for the total column density of singly ionized carbon (C+) in the optically thick photon dominated regions (PDRs) of far-UV irradiated (star-forming) molecular clouds. We derive a simple formula for the C+ column as a function of the cloud (hydrogen) density, the far-UV field intensity, and metallicity, encompassing the wide range of galaxy conditions. When assuming the typical relation between UV and density in the cold neutral medium, the C+ column becomes a function of the metallicity alone. We verify our analysis with detailed numerical PDR models. For optically thick gas, most of the C+ column is mixed with hydrogen that is primarily molecular (H2), and this "C+/H2" gas layer accounts for almost all of the `CO-dark' molecular gas in PDRs. The C+/H2 column density is limited by dust shielding and is inversely proportional to the metallicity down to ~0.1 solar. At lower metallicities, H2 line blocking dominates and the C+/H2 column saturates. Applying our theory to CO surveys in low redshift spirals we estimate the fraction of C+/H2 gas out of the total molecular gas to be typically ~0.4. At redshifts 1

Neanderthals and Anatomical Modern Humans at Cueva del Arco (Murcia, Spain). Comparison of their hunting and consuming patterns

description: Cueva del Arco is an archaeological site situated in the Mediterranean region of the Iberian Peninsula. The site comprises several cavities, named A to E, which contain a sequence from the Palaeolithic to the Neolithic period. Cavity D is particularly noteworthy for its Palaeolithic art. The most comprehensive and well-represented sequence from the site is found in cavity A, where levels from the Middle Palaeolithic and Upper Palaeolithic have been identified. This study presents the analysis of faunal remains from level III (Mousterian, older than c. 55 ka BP) and level II (Gravettian, ca. 33.8–32.0 ka cal BP) found in this cavity.

The main objective of this work is to compare the subsistence behaviour of two distinct human groups, Neanderthals and Anatomical Modern Humans, who used the same dwelling. A zooarchaeological and taphonomic analysis was conducted to achieve this goal.

The assemblages consist of several species of ungulates, carnivores, and leporids. Leporids are the most abundant group (ca. 90%), while ungulates mainly comprise Capra pyrenaica, with few remains from Bos primigeniu, Equus ferus, and Cervus elaphus. The assemblage is highly fragmented and diagenetically altered, though some anthropogenic and non-anthropogenic modifications could be identified.

The comparison reveals minor variations in the taxonomic composition, age-at-death, and resource exploitation, including thermal alterations, percussion marks, cut-marks, and non-anthropogenic modifications. Additionally, the study of the material culture suggests that both Neanderthal and Gravettian human occupations were brief and infrequent, and faunal study should help to better understand their nature.

description: The true slime mold \textit{Physarum polycephalum} has the remarkable capability to perform self-organized activities such as network formation among food sources. Despite well reproducing the emergence of slime networks, existing models are limited in the investigation of the minimal mechanisms, at the microscopic scale, that ensure robust problem-solving capabilities at the macroscopic scale. To this end, we develop three progressively more complex multi-agent models to provide a flexible framework to understand the self-organized foraging and network formation behaviors of \textit{Physarum}. The hierarchy of models allows for a stepwise investigation of the minimal set of rules that allow bio-inspired computing agents to achieve the desired behaviors on nutrient-poor substrates. By introducing a quantitative measure of connectedness among food sources, we assess the sensitivity of the model to user-defined and bio-inspired parameters, as well as the robustness of the model to parameter heterogeneity across agents. We ultimately observe the robust emergence of pattern formation, in line with experimental evidence. Overall, our study sheds light onto the basic mechanisms of self-organization and paves the way towards the development of decentralized strategies for network formation in engineered systems, focusing on trade-offs between biological fidelity and computational efficiency.

description: Two-spotted spider mite causes significant damage to various crops, often requiring synthetic acaricides for their control. However, the frequent use of these products causes several environmental problems. Thus, this work aimed to evaluate the acaricidal action, using the application by fumigation on female adults of Tetranychus urticae of essential oil from the leaves of Rosmarinus officinalis L., and its major compound, α-pinene. In addition, the essential oil was characterized by gas chromatography and mass spectrometry. α-pinene was the compound with the highest relative area in the oil (29.2%). In fumigation tests, α-pinene showed more significant toxicity than rosemary essential oil on two-spotted spider mite females with LC50 and LC90 values of 1.58 and 49.61 µL/L air, showing the impact of the chemical composition of the essential oil on the biological activity.
