description: Esta presentación es parte de los avances en el proyecto Efectos del estrés evaporativo sobre los flujos ecosistémicos en ecosistemas y agrosistemas en la cuenca del Río Usumacinta, México. Dicho proyecto iniciado en 2022 pretende comprender el comportamiento de diversos ecosistemas presentes en la cuenca, en relación a sus usos de energía, agua, carbono, ante la variabilidad estacional y los ciclos ENSO que pueden llegar a exacerbar las condiciones meteorológicas y climáticas hacia disturbios como sequías. Particularmente las sequías pueden inducir un importante estrés evaporativo en las comunidades vegetales que puede identificarse en la forma de desviaciones del comportamiento fenológico y estacional observado con mayor frecuencia respecto de la productividad primaria (índices de vegetación).

Se comparten los datos de las variables analizadas que corresponden a las estadísticas resumen de la cobertura de pastizales y otros ecosistemas presentes en la cuenca del Río Usumacinta en México. Estas coberturas corresponden a la la Serie VI de Uso de suelo y vegetación del Instituto Nacional de Estadística Geografía e Informática, INEGI, 2016, USV Serie VI.

Se obtuvieron datos del sensor MODIS para el periodo 2010 a 2021, tales como el Índice de Vegetación Realzado (EVI, 250 m, MOD13Q1), la Evapotranspiración real y potencial (ET y PET, 500 m, MOD16A2);  todos solicitados a través de la plataforma AppEEARS.

Adicionalmente se trabajó con datos de estaciones meteorológicas del Servicio Meteorológico Nacional SMN para el mismo periodo que los datos de imágenes MODIS. Dado que algunas estaciones no presentan datos completos, se desarrollo un script en R para el llenado de datos faltantes en las series de tiempo de precipitación acumulada diaria.

En esta publicación se comparten también la coberturas de ecosistemas analizados en formato shapefile junto con los resultados de los Análisis de Componentes Principales (ACP), aplicados a EVI y a la Fracción evaporativa fET, la cual resulta del cociente entre ET y PET. Se aplico el método de descomposición por valor singular sugerido para matrices rectangulares de datos. Este análisis se realizó en el software Geoda v.1.14.0, el cual es un software libre. Para más detalles sobre la implementación de este método consultar ACP.

description: Ultrafast pump-probe spectroscopy with high temporal and spectral resolutions provides new insight into ultrafast nonequilibrium phenomena. We propose that transient interference between pump and probe pulses is realized in pump-probe spectroscopy of band and Mott insulators, which can be observed only after recent developments of ultrafast spectroscopic techniques. A continuum structure in the excitation spectrum of band insulators is found to act as a medium for storing the spectral information of the pump pulse, and the spectrum detected by the probe pulse is interfered with by the medium, generating the transient interference in the energy domain. We also demonstrate the transient interference in the presence of electron correlations in a one-dimensional half-filled Hubbard model. Furthermore, bosons coupled to electrons additively contribute to the interference. Our finding will provide an interpretation of probe-energy-dependent oscillations recently observed in the pump-probe spectrum for a two-dimensional Mott insulator.

description: We compute the power spectra in the cosmic microwave background and cold dark matter (CDM) fluctuations seeded by strings, using the largest string simulations performed so far to evaluate the two-point functions of their stress energy tensor. We find that local strings differ from global defects in that the scalar components of the stress-energy tensor dominate over vector and tensor components. This result has far reaching consequences. We find that cosmic strings exhibit a single Doppler peak of acceptable height at high $\ell$. They also seem to have a less severe bias problem than global defects, although the CDM power spectrum in the ``standard'' cosmology (flat geometry, zero cosmological constant, 5% baryonic component) is the wrong shape to fit large scale structure data.

description: We consider SU(N) Chern-Simons theory coupled to a scalar field in the fundamental representation at strictly zero temperature and finite chemical potential for the global U(1)_B particle number or flavour symmetry. In the semiclassical regime we identify a Bose condensed ground state with a vacuum expectation value (VEV) for the scalar accompanied by noncommuting background gauge field matrix VEVs. These matrices coincide with the droplet ground state of the Abelian quantum Hall matrix model. The ground state spontaneously breaks U(1)_B and Higgses the gauge group whilst preserving spatial rotations and a colour-flavour locked global U(1) symmetry. We compute the perturbative spectrum of semiclassical fluctuations for the SU(2) theory and show the existence of a single massless state with a linear phonon dispersion relation and a roton minimum (and maximum) determining the Landau critical superfluid velocity. For the massless scalar theory with vanishing self interactions, the semiclassical dispersion relations and location of roton extrema take on universal forms.

description: We present a novel approach to the study of epidemics on networks as thermodynamic phenomena, quantifying the thermodynamic efficiency of contagions, considered as distributed computational processes. Modelling SIS dynamics on a contact network statistical-mechanically, we follow the Maximum Entropy (MaxEnt) principle to obtain steady-state distributions and derive, under certain assumptions, relevant thermodynamic quantities both analytically and numerically. In particular, we obtain closed-form solutions for some cases, while interpreting key epidemic variables, such as the reproductive ratio R0 of a SIS model, in a statistical mechanical setting. On the other hand, we consider configuration and free entropy, as well as the Fisher information, in the epidemiological context. This allowed us to identify criticality and distinct phases of epidemic processes. For each of the considered thermodynamic quantities, we compare the analytical solutions informed by the MaxEnt principle with the numerical estimates for SIS epidemics simulated on Watts–Strogatz random graphs.

description: The present status of the distance scale to Galactic globular clusters is reviewed. Six distance determination techniques which are deemed to be most reliable are discussed in depth. These different techniques are used to calibrate the absolute magnitude of the RR Lyrae stars. The various calibrations fall into three groups. Main sequence fitting using Hipparcos parallaxes, theoretical HB models and the RR Lyrae in the LMC all favor a bright calibration, implying a `long' globular cluster distance scale. White dwarf fitting and the astrometric distances yield a somewhat fainter RR Lyrae calibration, while the statistical parallax solution yields faint RR Lyrae stars implying a `short' distance scale to globular clusters. Various secondary distance indicators discussed all favor the long distance scale. The `long' and `short' distance scales differ by (0.31+/-0.16) mag. Averaging together all of the different distance determinations yields Mv(RR) = (0.23+/-0.04)([Fe/H] + 1.6) + (0.56+/-0.12) mag.

description: The aim of this review was to critically synthesize barriers and facilitators to the use of AAC systems by children with autism spectrum disorder (ASD) and their communication partners. Qualitative data related to barriers and facilitators were synthesized from 42 studies located using a systematic search. A diverse range of studies was examined in order to identify the span of barriers and facilitators reported in the literature. Included studies comprised quasi-experimental, non-experimental, and qualitative study designs. The full range of unaided, low-tech aided, and high-tech aided AAC systems were reported across the included studies. The critical synthesis identified 5 themes to which barriers and facilitators are related: (a) Intervention Services and Service Providers, (b) AAC Systems and Technologies (c), Communication Partners of Children with ASD, (d) Parents of Children with ASD, and (e) Children with ASD. The findings suggest that barriers and facilitators to the use of AAC vary across individuals, AAC modalities, and environments. By identifying barriers and facilitators to the use of AAC experienced by children with ASD and their communication partners, service providers might be better equipped to support these children and their communication partners. Clinical implications and future research directions are discussed.

description: Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous wave electron vortex beams are commonly prepared via passive phase masks imprinting a transverse phase modulation on the electron's wave function. Here, we show that femtosecond chiral plasmonic near fields enable the generation and dynamic control on the ultrafast timescale of an electron vortex beam. The vortex structure of the resulting electron wavepacket is probed in both real and reciprocal space using ultrafast transmission electron microscopy. This method offers a high degree of scalability to small length scales and a highly efficient manipulation of the electron vorticity with attosecond precision. Besides the direct implications in the investigation of nanoscale ultrafast processes in which chirality plays a major role, we further discuss the perspectives of using this technique to shape the wave function of charged composite particles, such as protons, and how it can be used to probe their internal structure.

description: We report on the detection of dark matter in the cluster Abell 2218 using the weak gravitational distortion of background galaxies. We find a highly significant, coherent detection of the distortion in the images of the background galaxies. The inferred 2D mass distribution has a peak that is coincident with the optical and X-ray centroid. The qualitative distributions of the cluster light, the X-ray emission and the dark matter are similar and the projected total mass, gas, and light surface densities are consistent with a $r^{-1}$ profile at distance of $r > 180^{\prime\prime}$ from the cluster cD galaxy. Using the weak lensing technique, we determine a lower bound for the total mass in A2218 of $(3.9 \pm 0.7) \times 10^{14}$~h$^{-1}$~M$_\odot$ within a fiducial aperture of radius 0.4~h$^{-1}$Mpc. The associated cluster mass-to-light ratio is $(440 \pm 80)$~h~$M_\odot/L_{\odot B}$. The mass estimated by the weak lensing method is consistent with that inferred from the X-ray data under the assumption of hydrostatic equilibrium and we derive an upper bound for the gas-to-total mass ratio at 400~h$^{-1}$kpc of $M_{gas}/M_{tot} = (0.04 \pm 0.02)$h$^{-3/2}$.

description: Having examined the application of quasi-equilibrium to hydrostatic silicon burning in Paper I of this series, Hix & Thielemann (1996), we now turn our attention to explosive silicon burning. Previous authors have shown that for material which is heated to high temperature by a passing shock and then cooled by adiabatic expansion, the results can be divided into three broad categories; \emph{incomplete burning}, \emph{normal freezeout} and \emph{$α$-rich freezeout}, with the outcome depending on the temperature, density and cooling timescale. In all three cases, we find that the important abundances obey quasi-equilibrium for temperatures greater than approximately 3 GK, with relatively little nucleosynthesis occurring following the breakdown of quasi-equilibrium. We will show that quasi-equilibrium provides better abundance estimates than global nuclear statistical equilibrium, even for normal freezeout and particularly for $α$-rich freezeout. We will also examine the accuracy with which the final nuclear abundances can be estimated from quasi-equilibrium.

description: The dynamic behavior of bundles of actin filaments growing against a loaded obstacle is investigated through a generalized version of the standard multi filaments Brownian Ratchet model in which the (de)polymerizing filaments are treated not as rigid rods but as semi-flexible discrete wormlike chains with a realistic value of the persistence length. By stochastic dynamic simulations we study the relaxation of a bundle of $N_f$ filaments with staggered seed arrangement against a harmonic trap load in supercritical conditions. Thanks to the time scale separation between the wall motion and the filament size relaxation, mimiking realistic conditions, this set-up allows us to extract a full load-velocity curve from a single experiment over the trap force/size range explored. We observe a systematic evolution of steady non-equilibrium states over three regimes of bundle lengths $L$. A first threshold length $Λ$ marks the transition between the rigid dynamic regime ($LΛ$), where the velocity $V(F,L)$ is an increasing function of the bundle length $L$ at fixed load $F$, the enhancement being the result of an improved level of work sharing among the filaments induced by flexibility. A second critical length corresponds to the beginning of an unstable regime characterized by a high probability to develop escaping filaments which start growing laterally and thus do not participate anymore to the generation of the polymerization force. This phenomenon prevents the bundle from reaching at this critical length the limit behavior corresponding to Perfect Load Sharing.

description: An improved method for subtracting contaminants from Cosmic Microwave Background (CMB) sky maps is presented, and used to estimate how well future experiments will be able to recover the primordial CMB fluctuations. We find that the naive method of subtracting foregrounds (such as dust emission, synchrotron radiation, free-free-emission, unresolved point sources, etc) on a pixel by pixel basis can be improved by more than an order of magnitude by taking advantage of the correlation of the emission in neighboring pixels. The optimal multi-frequency subtraction method improves on simple pixel-by-pixel subtraction both by taking noise-levels into account, and by exploiting the fact that most contaminants have angular power spectra that differ substantially from that of the CMB. The results are natural to visualize in the two-dimensional plane with axes defined by multipole l and frequency v. We present a brief overview of the geography of this plane, showing the regions probed by various experiments and where we expect contaminants to dominate. We illustrate the method by estimating how well the proposed ESA COBRAS/SAMBA mission will be able to recover the CMB fluctuations against contaminating foregrounds.

description: Objective: To examine whether the presence of amniotic fluid sludge (AFS) could increase the risk of preterm delivery in women with a cervical length (CL) of less than 25 mm. Materials and methods: This is a retrospective cohort study of 110 women who were 14–30 weeks pregnant with a singleton gestation and a CL of less than 25 mm. The primary outcomes were defined as preterm delivery before 34 weeks and preterm delivery before 37 weeks. The secondary outcome was defined as preterm premature rupture of membranes (PPROM) prior to preterm delivery. Risk factors for preterm delivery were defined as AFS, subchorionic hematoma (SCH), history of preterm delivery, CL of less than 20 mm, and CL of less than 15 mm. A univariate analysis was performed to assess the primary and secondary outcomes according to the presence or absence of each risk factor. A multiple logistic regression analysis was performed to evaluate the parameters, using a significance of p Results: A significantly increased risk of preterm delivery was found in the group of women with AFS who actually did deliver prior to 34 weeks (p p = .001; OR 4.46; 95% CI 1.76–11.3), and who had PPROM (p p = .001; OR 5.86; 95% CI 2.11–16.3). Conclusion: The presence of AFS was an independent risk factor for preterm delivery before 34 weeks in women with a CL less than 25 mm.

description: Farmer participatory research (FPR) is difficult to monitor and review because it uses a process' approach; it is done in variable, unpredictable situations; it produces some outputs that are hard to measure objectively; and it involves different types of stakeholder, each with their own aims and ideas of success or failure. For these reasons, FPR projects tend to have permeable boundaries, with sometimes important spillover effects, and less than direct relationships between inputs and outputs. This paper examines how far a conventional project management tool, the logframe, can be adapted to the monitoring and review of FPR. Normally used in 'blueprint' projects, the logframe presents some difficulties in handling those with process' characteristics. But it has a number of strengths: it requires clear specification of purposes, anticipated outputs, activities, and the relationship among them, as well as performance indicators and means of assessing them. Also, it is becoming almost universally adopted by funding agencies, so organisations using FPR may in future have to structure their proposals and monitoring activities in logframe format. FPR aims to achieve one or more of three outputs using participatory methods: W to develop improved agricultural technologies in response to farmers' needs; (ii) to develop the human resources of the farmers and collaborating organisations; (iii) to develop the institutional capacity of farmers' groups and collaborating organisations. For the first of these, the relationship between the project activities and its outputs is fairly direct, making this fairly easy to monitor. It is less direct with the second and third, but can still be captured by suitably adapted project management tools. Because of their mandates and philosophies, NGOs and public sector organisations differ in how they view participation'. Government agencies are concerned largely with (i). NGOs, on the other hand, are interested in participation mainly as a way to empower the poor. NGOs are therefore concerned at least as much with (ii) and OW as with (i). This paper offers a generic logframe that readers can adapt to suit their own FPR projects. For each output, it provides illustrative performance indicators that might be relevant to each of the two most important groups of stakeholders (researchers and farmers). The paper also suggests some means of verification for each of the indicators. Readers should select, adapt and add to these to suit their own situations. An overall conclusion is that, whilst logframes can be constructed to cater for many of the requirements of monitoring and reviewing FPR, they have to be updated frequently to incorporate process' changes, and become cumbersome with the more empowering dimensions of FPR. Here they can usefully be complemented by more inductive techniques such as process documentation and monitoring.

description: This paper presents a partial equilibrium model for the analysis of some aspects of international trade and trade policy for a less developed country which exports intermediate goods in an imperfectly competitive market structure and within which some competing firms are multinational enterprises (MNEs). It then examines the effects on exports and the gains from trade for a LDC of exogenous shocks originating in the economies involved in trade; the effects of a higher degree of foreign ownership of the export activities of the LDC; and the effects of an increase in the degree of competitiveness among firms serving the market for the finished product which uses the intermediate goods exported by the LDC.

description: In aerospace industry, gears are the most common parts of a mechanical transmission system. Gear pitting faults could cause the transmission system to crash and give rise to safety disaster. It is always a challenging problem to diagnose the gear pitting condition directly through the raw signal of vibration. In this paper, a novel method named augmented deep sparse autoencoder (ADSAE) is proposed. The method can be used to diagnose the gear pitting fault with relatively few raw vibration signal data. This method is mainly based on the theory of pitting fault diagnosis and creatively combines with both data augmentation ideology and the deep sparse autoencoder algorithm for the fault diagnosis of gear wear. The effectiveness of the proposed method is validated by experiments of six types of gear pitting conditions. The results show that the ADSAE method can effectively increase the network generalization ability and robustness with very high accuracy. This method can effectively diagnose different gear pitting conditions and show the obvious trend according to the severity of gear wear faults. The results obtained by the ADSAE method proposed in this paper are compared with those obtained by other common deep learning methods. This paper provides an important insight into the field of gear fault diagnosis based on deep learning and has a potential practical application value.

description: We explore the important fundamental question of how quantum information is localized in quantum gravity, in a perturbative approach. Familiar descriptions of localization of information, such as via tensor factorization of the Hilbert space or a net of commuting subalgebras of operators, conflict with basic gravitational properties -- specifically gauge invariance -- already at leading order in perturbation theory. However, previous work found that information can be classically localized in a region in a way such that measurements, including those of the gravitational field, outside the region are insensitive to that information, and only measure total Poincare charges. This paper shows that, working to leading order in the gravitational coupling, a similar quantum result holds, leading to a definition of a "gravitational splitting" on the Hilbert space for gravity. Such localization of information also argues against a role for "soft hair" in resolving the information problem for black holes. This basic mathematical structure plausibly plays a foundational role in the quantum description of gravity.

Distance-based methods for detecting associations in structured data with applications in bioinformatics
Creators: name: Minas, Christopher
Publisher: name: Imperial College London

description: In bioinformatics applications samples of biological variables of interest can take a variety of structures. For instance, in this thesis we consider vector-valued observations of multiple gene expression and genetic markers, curve-valued gene expression time courses, and graph-valued functional connectivity networks within the brain. This thesis considers three problems routinely encountered when dealing with such variables: detecting differences between populations, detecting predictive relationships between variables, and detecting association between variables. Distance-based approaches to these problems are considered, offering great flexibility over alternative approaches, such as traditional multivariate approaches which may be inappropriate. The notion of distance has been widely adopted in recent years to quantify the dissimilarity between samples, and suitable distance measures can be applied depending on the nature of the data and on the specific objectives of the study. For instance, for gene expression time courses modeled as time-dependent curves, distance measures can be specified to capture biologically meaningful aspects of these curves which may differ. On obtaining a distance matrix containing all pairwise distances between the samples of a given variable, many distance-based testing procedures can then be applied. The main inhibitor of their effective use in bioinformatics is that p-values are typically estimated by using Monte Carlo permutations. Thousands or even millions of tests need to be performed simultaneously, and time/computational constraints lead to a low number of permutations being enumerated for each test. The contributions of this thesis include the proposal of two new distance-based statistics, the DBF statistic for the problem of detecting differences between populations, and the GRV coefficient for the problem of detecting association between variables. In each case approximate null distributions are derived, allowing estimation of p-values with reduced computational cost, and through simulation these are shown to work well for a range of distances and data types. The tests are also demonstrated to be competitive with existing approaches. For the problem of detecting predictive relationships between variables, the approximate null distribution is derived for the routinely used distance-based pseudo F test, and through simulation this is shown to work well for a range of distances and data types. All tests are applied to real datasets, including a longitudinal human immune cell M. tuberculosis dataset, an Alzheimer’s disease dataset, and an ovarian cancer dataset.

description: Efficient oil adsorption and recovery is a generous universal importance for future energy demand and environmental protection. Adsorbents based on 2D flatland with engineered surfaces can overcome the limitations of conventional methods for selective oil adsorption. Here, we report magnetic hydrophobic/oleophilic graphitic C3N4 nanosheets that exhibit excellent oil sorption performance and rapid removal of adsorbed oil using an external magnet. Combining porous and nanosheets structure along with magnetic FeNi3 and fatty acid surface functionalization make the system an efficient adsorbent for adsorbing and separating crude oil from water. The graphitic sheets selectively adsorb crude oil with enhancement of thickness up to 9 folds and mass by 4.5 times than the pristine nanocomposite system. The smart adsorption property of g-C3N4@FeNi3 has been realized through comprehensive adsorption kinetics and inclusive isotherm studies. The nanocomposite can be further recycled and reused in an eco-friendly manner for oil adsorption and recovery.

An investigation of the mechanical performance of Z-pin reinforced composites
Creators: name: Fert, Marcin Maciej
Publisher: name: Imperial College London
Year: 2015

description: Fibrous composites, having excellent mechanical properties in the direction of the fibres, have lower mechanical properties in the through thickness direction, controlled by resin. Z-pinning improves the delamination toughness (up to 500%) with a relatively modest reduction to the in-plane mechanical properties (typically 5–15%). This experimental study investigates the mechanical performance of Z-Pins bridging an existing delamination in fibre reinforced resin composites under pull-out (Mode I), shear-out (Mode II) and mixed mode loading conditions using a specially designed testing rig. In Mode II the opening displacement was restricted and measured by springs of three different stiffnesses. A new technique of needle assisted Z-Pin insertion was developed, in which prepreg panels were perforated with a steel needle in order to insert Z-Pins. This technique ensured the desired orientation of Z-Pins, improved pinning quality and removed the necessity of costly preforms used in the traditional UAZ method.Test specimens were blocks (15 mm x 15 mm x 6mm thick) of carbon-epoxy IM7/8552 composite in unidirectional (UD) and quasi-isotropic (QI) stacking sequences, with PTFE delamination film in the mid-plane recreating an existing crack, bridged with a single T300/9310 Z-Pin or a group of four pins of either 0.28 mm or 0.51 mm diameter. Three phases of pull-out were identified: Linear Phase (linear force-displacement curve), Crack Formation (unstable crack propagation phase) and Frictional Sliding (friction-controlled pull-out). Two phases of shear-out were identified: Linear Phase (with no energy loss) and Breaking Phase (where the fibrous structure of the Z-Pins is fractured, ending with Z-Pin breakage). In mixed mode specimens behaved similarly to pull-out for the pin angles up to 45°. For higher angles the behaviour was more similar to pure shear-out. The influence of the Z-Pin diameter, z-pinning depth, distance between adjacent Z-Pins, composite stacking sequence and pull-out speed on the Z-Pins behaviour were investigated. The results will be useful in the formulation of improved Z-Pin bridging laws for use in finite element models.

description: The Canada-France Redshift Survey has been undertaken to provide a large well-defined sample of faint galaxies at high redshift in which the selection criteria match as closely as possible those of samples of nearby galaxies. The survey is designed to have a median redshift of z ~ 0.6 corresponding to a look-back time of half the present age of the Universe for Omega ~ 1. Such a survey can then be used for studying many different aspects of the evolution of galaxies over the interval 0 < z < 1. In this paper we describe the selection of the fields, the multicolor imaging observations and the construction and validation of the photometric catalogs. Particular attention is paid to quantifying the unavoidable selection effects in surface brightness and their impact on the survey is assessed in the context of the properties of known populations of galaxies. The photometric catalogs contain several thousand objects brighter than I_{AB}< 22.5 and are essentially complete for central surface brightnesses as faint as $μ_{AB}(I)$ $\sim$ 24.5 mag arcsec$^{-2}$. This should be sufficient to include both normal surface brightness galaxies and prototypes of extreme low surface brightness galaxies.
