ABSTRACT The objective of this study was to evaluate whether the inhibition of gibberellin biosynthesis affects the morphophysiological traits of potted ornamental Capsicum baccatum and Capsicum annuum growing under shade house conditions. Plants maintained in 2.7 L pots were arranged in a completely randomized design in a 2x4 factorial consisting of two pepper cultivars Chapéu-de-frade (C. baccatum) and Vulcão (C. annuum) and four paclobutrazol (PBZ) concentrations (0, 25, 50, and 75 mg L-1) with four replicates. At 30, 45, and 60 days after treatment, the plants were analyzed, and data were submitted to the analysis of general and regression variance. Gibberellin biosynthesis inhibition affected the morphophysiological and biochemical evaluations. For most evaluated traits, no interaction between factors was observed, suggesting that both pepper cultivars had a similar response to the growth regulator. PBZ-induced inhibition of gibberellin biosynthesis improved plant water status, which enhanced the vigor of potted pepper plants. The dramatic reduction of upper leaves promoted by plant growth regulators compared to basal ones negatively impacted the visual ornamental aspect of Chapéu-de-frade peppers.

Published: April 2022

ABSTRACT Root-knot nematodes (Meloidogyne incognita) are responsible for causing great damage to tomato crop, demanding various specific management strategies. In order to find an effective alternative to control this pathogen, the aim of this study was to test the rosemary (Rosmarinus officinalis) extract in formulation with hydrogel. The formulation was used at doses of 0.25; 0.50; 0.75; 1.00 and 1.25 g per pit, at seedling transplanting, and as controls, 1.25 g of hydrogel (without rosemary) and absolute control (only water). The nematological variables evaluated were number of egg masses, number of galls, total nematodes per root, and reproduction factor. To verify whether plant resistance induction occurred, root samples were collected at different time periods and the activity of the enzymes phenylalanine ammonia-lyase (FAL), peroxidase (POX) and polyphenoloxidase (PFO) were measured. For the nematological variables, we verified proportional dose-dependent reduction of nematode infection, indicating its effectiveness in disease control. For the enzymes, FAL showed no significant change in any treatment or time period tested, whereas POX and PFO showed peaks of activity in different treatments and times, mainly at the dose 1.25 g of the formulation. These results indicated that the control of M. incognita in tomato crop can be achieved by a direct effect of the rosemary extract on the nematode population as well as by plant resistance in response to the pathogen action.

Published: April 2022

ABSTRACT Sweet corn (Zea mays subsp. saccharata) is mainly intended for industrial processing. Optimizing time and costs during plant breeding is fundamental. An alternative is the use of high-throughput phenotyping (HTP) indirect associated with agronomic traits and chlorophyll contents. This study aimed to (i) verify whether HTP by digital images is useful for screening sweet corn genotypes and (ii) investigate the correlations between the traits evaluated by conventional methods and those obtained from images. Ten traits were evaluated in seven S3 populations of sweet corn and in two commercial hybrids, three traits by classical phenotyping and the others by HTP based on RGB (red, green, blue) and multispectral imaging analysis. The data were submitted to the analyses of variance and Scott-Knott test. In addition, a phenotypic correlation graph was plotted. The hybrids were more productive than the S3 populations, showing an efficient evaluation. The traits extracted using HTP and classical phenotyping showed a high degree of association. HTP was efficient in identifying sweet corn genotypes with higher and lower yield. The vegetative canopy area (VCA), normalized difference vegetation index (NDVI), and visible atmospherically resistant index (VARI) indices were strongly associated with grain yield.

Abstract Aim We evaluated the leaf decomposition in a first order stream of the exotic Eucalyptus grandis and two native species Lithraea molleoides and Maytenus aquifolium common riparian trees in a tropical forest. Besides seasonal effects on leaf decomposition of the three species were evaluated. Methods The dried leaves were incubated in litter bags” of 20 x 20 cm with 10 mm of mesh opening in two different treatments and at two times of the year (dry and rainy): i) 48 “litter bags” containing 4 g of leaves, being 24 “litter bags” with leaves of L. molleoides and 24 with E. grandis and ii) 48 “litter bags” containing 4 g of leaves, being 24 “litter bags” with of M. aquifolium and 24 with leaves of E. grandis. After 2, 7, 14, 21, 28 and 60 days of immersion, randomly removed four “litter bags” of each species to carry out the analyzes. Results The weight loss in the first two days was between 20% and 40% in both experiments and in both seasons of the year. Leaf decomposition was higher in L. molleoides (k=0.0062 ± 0.0002 day-1) than in E. grandis (k=0.0039 ± 0.0005 day-1) in the dry season and higher in L. molleoides (k=0.0185 ± 0.0002 day-1) than E. grandis (k=0.0164 ± 0.0003 day-1) in the rainy season. In the second experiment the decomposition rates were higher in M. aquifolium (k=0.0151 ± 0.0009 day-1) than E. grandis (k=0.0149 ± 0.0006 day-1) in the dry season and higher in M. aquifolium (k=0.0174 ± 0.0001 day-1) than E. grandis (k=0.0164 ± 0.0002 day-1) in the rainy season. Besides, the results indicate that there is an effect of both the dry and rainy season and the native or exotic species on the decomposition rates. Conclusions Our findings indicate that, the seasons are likely to influence leaf decomposition, and future studies should consider seasonality. Furthermore, the exotic species had a lower decomposition rate compared to native species, which reinforces that the replacement of native riparian vegetation by exotic species such as eucalyptus can interfere on the quality of allochthonous resources and on the cycling of nutrients in neotropical streams.
Barriers for the circular reuse of steel in the Belgian construction sector: an industry-wide perspective

Published: April 2022

The construction industry is responsible for approximately 40% of the worldwide material consumption. Therefore, the transition to a circular construction industry is of primary importance. In a circular economy, the maximum usage and preservation of materials and energy is suggested. The reuse of components is considered a circular economy best practice. This paper investigates the reuse of steel construction elements in Belgium and identifies the existing barriers. A series of semi-structured interviews was conducted with a wide range of stakeholders representing the whole Belgian construction sector. The identified critical barriers to steel reuse are cost, demand and time. Subsequently, these barriers were tested and quantified in practice in co-operation with a demolition contractor. A comparison was made between demolition and deconstruction of steel porticos considering cost, time and demand. It was found that, in practice, demand is the most pressing obstacle. Overcoming this obstacle will require a coordinated approach throughout the Belgian construction chain: improved deconstruction procedures on-site, a platform to match supply and demand, standardisation of reusable steel elements, governmental policies and design strategies.
4IR in South Africa and some of its educational implications
Authors: Carrim Nazir
Published: April 2022

This article focuses on the attempts to construct the fourth industrial revolution (4IR) in South Africa, and some of its educational implications. Using Foucault's (1972) notion of enunciative modalities, and drawing empirically on statements made by the World Economic Forum, the South African government, and some South African universities, the article shows that it is people in governments, the economy, and academia who are positioned as the authorities of delimitation who define what the 4IR is, and who bring it into visibility. The article then shows that, inevitability, STEM matter, instrumentalism, and benevolence are the coordinates around which the 4IR is being articulated. In discussing these coordinates, some of the educational implications of such articulations are explored. These include the technicist way in which education is viewed, the lack of adequate recognition of the inequalities in the educational system, and the problems with customised curricula that 4IR assumes, and which erode the possibilities of developing deep learning.

Published: April 2022

Pollution of aquatic ecosystems is constantly increasing with the increase in anthropogenic activities all over the world with negative effects on the constituent biota. The current study addressed the possibility of remedying the effects posed to the tissues of Clarias gariepinus fingerlings (3-11g initial weight) exposed to lead nitrate over a 12 week period. The treatment groups were Pb only and PbVE (Pb+vitamin E) with T1-T4 and replicate in each case. The sub-lethal treatments of lead nitrate concentrations are as follow: 00 (control), 26mg/L (T1), 44mg/L (T2), 61mg/L (T3) and 79mg/L (T4). 26mg/L concentration of the vitamin was applied to every treatment and replicate of the PbVE group. At the end of the exposure period, gills, liver, and kidneys were excised from the samples and preserved in 10% formalin for histopathological analyses. From the results; the livers of the samples of C. gariepinus exposed to sub-lethal concentration of Pb only group displayed aggregation and lumping together of the hepatocytes, massive necrosis and shattering of the hepatocytes, vacoulation with greater severity as the concentration increased. The samples of PbVE treatment group showed preserved hepatocytes, reduced aggregation and vacoulation of the cells, gradual recovery of the cell nucleus and cytoplasm, normal tissue architecture, and hepatocytes similar to control samples in T1-T3. In the kidneys of Pb only group, there were massive necrosis and vacoulation, shattering of cells, tissue edema, and massive lumping of cells together, especially in higher concentrations. The PbVE treatments displayed reduced necrosis and cells aggregating together coupled with reduced vacoulation, preserved cells, and cells with cytoplasm returning to normal. But these were not sustained in the highest concentration. In the gills of the Pb only group, there was rarefied gill filament with ruptured lamellae, shattered gill arch, and filaments ruptured primary and secondary lamellae with greater severity in higher concentrations. The PbVE group displayed how the gill arch and filaments with the primary and secondary lamellae were gradually restored to a certain extent similar to the control. In all the organs the alteration and amelioration of the architecture were concentration-dependent. Therefore, a proportionate concentration of the vitamin can facilitate faster tissue damage recovery in heavy metal exposure.

Published: April 2022

In comparison to the traditional solutions, active bearings offer great operating flexibility, ensure better operating conditions over a wider range of rotational speeds and are safe to use. In order to ensure optimum bearing performance a bearing control system is used that adapts
different geometries during device operation. The selection of optimal controller parameters requires the use of modern optimization methods that make it possible to quickly achieve the assumed parameters. This article presents the method that has been employed to select the
parameters of a proportional integral derivative (PID) controller, in which both stochastic algorithms and hybrid methods have been compared.
The results show that all of the used algorithms were able to reach the global optimum but only the hybrid algorithm was repeatable in all runs within a low value of the standard deviation. The best solution will be proposed in the future to control an active foil bearing. Analysing of this paper would help to prevent failures of active foil bearing used in the designed rotating machine.

Published: April 2022

Cancellation of scheduled surgeries is a latent problem in Colombia, which encompasses negative consequences for the patient (physically and psychologically), the health care personnel (well-being, satisfaction, performance) and the institution (cost-effectiveness). The rate of cancellation varies between 2,7 - 7,6 %. Most cancellations are preventable and occur due to administrative or programming issues. In this document, we performed a review on the gaps of knowledge on this problem in Colombia, and we highlighted some points for the research agenda.

Authors: Colina-Vargas Yerlin Andrés , Vélez-Gaviria Manuela , Zapata-Correa Tatiana Andrea , Botero-Posada Luis Fernando , Gómez-Gallego Rocío , Marín-Pineda Diana Marcela
Published: April 2022

Antecedentes: existen pocos estudios referentes a las quejas presentadas acerca de los médicos, limitando la retroalimentación y la educación, aspectos que ayudan a mejorar los servicios de salud y la calidad de atención.
Objetivo: caracterizar las quejas con respecto a los médicos y sus consecuencias en Antioquia (2008-2013).
Métodos: estudio descriptivo transversal. Se revisó la totalidad de quejas presentadas ante el Tribunal de Ética Médica de Antioquia, 2008-2013, que contaran con pronunciamiento al segundo semestre de 2018. Se evaluaron las características del personal implicado, el evento que motivó la queja, las normas vulneradas y la sanción.
Resultados: se encontraron 679 médicos implicados en 461 quejas, 43,4 % médicos generales. El principal motivo para presentar queja fue la mala atención percibida por los pacientes (20,9 %), y la principal norma por la cual se abrieron procesos fue la Ley 23 Articulo15, que habla del consentimiento informado (17,3 %), siendo también la más sancionada (16,2 %). A la mayoría de involucrados (58,6 %) les archivaron los procesos por no encontrar fundamento en motivo de la queja; sin embargo, a 23 (3,4 %) les impartieron sanción, siendo grave con suspensión en ejercicio de la medicina en 60,8 %. Un 17,4 % de los casos tuvieron censura publica, 13 % amonestación privada y 8,7 % censura escrita privada o censura verbal pública.
Conclusiones: la omisión o mal diligenciamiento del consentimiento informado constituye el principal motivo de sanción; sin embargo, el verdadero detonante que lleva a presentar una queja, es la percepción de una mala atención. La educación ética transversal al ejercicio profesional es fundamental en la reducción de demandas por mala praxis.

Anaerobic digestion (AD) is a process of decomposition of organic matter in which the main product is a gaseous mixture called biogas, which has potential as a fuel. Anaerobic co-digestion (ACoD) is a technological alternative to improve the performance of the process, focused on balancing the C/N ratio and diluting inhibitory components. The literature highlights the increase in methane yield through ACoD. This investigation analyzed the mixing effects on methane yield kinetics, using articles that report kinetic coefficients in Cone and Gompertz models modified for binary and ternary mixtures. The analysis of the mixtures considered the sum of the contributions for each mixture using the adjusted kinetic coefficients for the monosubstrates. The mixing effects analysis compared the additive model fitted to the modified Cone and Gompertz models. The comparison made with the coefficients for the additive model and the experimental data presented relevant variations of 10%. This allowed to establish that the mixing effects can influence the methane yield as well as the kinetic constants of the process.
Conceptualización y Diagnóstico Dimensional del Trastorno de Personalidad en el CIE-11
Authors: Jiménez-Benítez Mercedes
Published: April 2022

Durante la pasada década se desarrollaron fuertes polémicas acerca de si continuar utilizando o no sistemas categoriales para el diagnóstico de los trastornos de personalidad, a raíz de la doble clasificación planteada por el Manual Diagnóstico y Estadístico de los Trastornos Mentales (DSM-5). En la actualidad, la nueva edición de la Clasificación Internacional de Enfermedades (CIE-11) adopta un enfoque completamente dimensional basado en la mejor evidencia posible, el cual supone un hito histórico respecto a la conceptualización y clasificación de los trastornos de personalidad en los sistemas diagnósticos. En este artículo se revisa la historia del diagnóstico del trastorno de personalidad y se presenta brevemente el nuevo modelo diagnóstico del CIE-11 para, a partir de estos contenidos y de algunos resultados de investigación, analizar sus ventajas respecto al diagnóstico categorial y plantear algunos interrogantes acerca de su validación empírica y sus posibles implicaciones, tanto para la práctica profesional como a nivel social.

Published: April 2022

Robust estimation of ground motions generated by scenario earthquakes is critical for many engineering applications. We leverage recent advances in generative adversarial networks (GANs) to develop a new framework for synthesizing earthquake acceleration time histories. Our approach extends the Wasserstein GAN formulation to allow for the generation of ground motions conditioned on a set of continuous physical variables. Our model is trained to approximate the intrinsic probability distribution of a massive set of strong-motion recordings from Japan. We show that the trained generator model can synthesize realistic three-component accelerograms conditioned on magnitude, distance, and VS30. Our model captures most of the relevant statistical features of the acceleration spectra and waveform envelopes. The output seismograms display clear P- and S-wave arrivals with the appropriate energy content and relative onset timing. The synthesized peak ground acceleration estimates are also consistent with observations. We develop a set of metrics that allow us to assess the training process’s stability and to tune model hyperparameters. We further show that the trained generator network can interpolate to conditions in which no earthquake ground-motion recordings exist. Our approach allows for the on-demand synthesis of accelerograms for engineering purposes.
Equivalence between ωn Source Time Functions and Those Proposed from Dynamic Finite-Source Modeling
Authors: Beresnev Igor A.
Published: April 2022

There is far-reaching equivalence between the source time functions inferred from dynamic rupture simulations and those corresponding to the kinematic models of slip radiating the generalized omega-n spectrum, in which the power n is allowed to take on noninteger values. First, the same two physical parameters of faulting—the final-fault displacement U and the peak rate of slip vm—govern the slip law in both cases. Second, in both models, the widths of the radiated far-field velocity pulses follow close analytical forms. Third, the full variety of temporal shapes of the dynamic source time functions, spanning the entire parameter space, closely corresponds to the variation in the omega-n shapes with n changing from 1.5 to 3.5, approximately. Smaller n lead to the source time functions that reach the maximum value of slip velocity faster: they cause greater asymmetry of the resulting far-field ground-displacement pulse and shorter duration of the positive velocity pulse. Fourth, in the frequency domain, the ωn spectrum, in which n changes in a narrower range from approximately 2 to 2.5, similarly includes nearly the entire range of possible dynamic Fourier spectra. The narrower range in n found in the frequency domain is explained by the constraints on the spectral slope imposed by the specific triangular shape of the dynamic functions. Fifth, in both dynamic and ωn models, the peak rate of slip vm is the parameter exerting dominant effect on the strength of fault’s high-frequency radiation, in the identical quantitative manner. It follows that the omega-n model of slip, in which n is allowed to vary, correctly captures the underlying physics of rupture.

Unilateral spinal anaesthesia is a technique used to avoid hemodynamic changes and early recovery. Adjuvants are added to prolong post operative analgesia, this study was done to compare nalbuphine (0.8mg) and fentanyl (20µg) as adjuvants to 0.5% bupivacaine Heavy in unilateral spinal anaesthesia for patients undergoing lower limb orthopaedic surgeries.

Randomized double blind study in patients posted for lower limb orthopaedic surgery in a teritiary care center.

Unilateral spinal anaesthesia was given to 68 eligible patients undergoing lower limb orthopaedic surgery with nalbuphine (0.8mg) and fentanyl (20µg) as adjuvants to 0.5% bupivacaine Heavy. Block characterstics, unilaterality, hemodynamic changes and recovery were noted.

Independent sample t-test was used to compare continuous variables with normal distribution and chi square test for categorical variables

Unilateral block was seen in 60 of 68 patients enrolled. Time to achieve T 10 level was comparable between both the groups in nalbuphine and fentanyl group (4.33±0.99 and 4.77 ± 0.89 respectively). Duration of sensory block was significantly lesser in nalbuphine group as compared to fentanyl group (170.67±15.34 and 178.83±15.04 respectively). However, there was no significant difference in duration of analgesia, 265.17 ± 17.73 in nalbuphine group and 260.23 ±31.03 in fentanyl group (p=0.45).

Nalbuphine due to its easy availability can be used as effective alternative to fentanyl as adjuvant in unilateral spinal anaesthesia.

This study aims to determine the effect of additional feed with depolarizing katuk leaves on the production and quality of colostrum and colostrum milk in Friesian Holstein dairy cows. There were 21 dairy cows that had just giving birth, divided into 3 groups of 7 each, namely the control group (complete feed), BKD (complete feed added with Depolarizing Katuk Powder), PKD (complete feed added with Depolarizing Katuk Pellet). Depolarizing katuk feed was given 100 grams per head per day as a feed additive. Parameters observed were feed consumption, production and quality of colostrum and colostrum milk. The results showed that there was no difference in the consumption of feed supplemented with depolarizing katuk leaves, colostrum production, milk density, total solid colostrum, Solid non-fat, lactose contents, and protein contents of colostrum and colostrum milk compared to the control group. Significant differences occurred in colostrum milk production, total solid colostrum milk, and fat content of colostrum and colostrum milk. It was concluded that depolarizing katuk leaves could be used as additional feed to increase the production and total solids of colostrum milk, and increase the fat content of colostrum and colostrum milk.   Keywords: colostrum, colostrum milk, depolarizing katuk leaf, Friesian Holstein

Soil was collected from ten points representing land, and grass samples were obtained by sampling from several points of the grazing area. Mineral content in soil, grass, and deer hair were analyzed using the atomic absorption spectrophotometry. The results showed that the level of Ca (0.03%) and P (0.016%) in the soil are deficient, Mn (1960 ppm), Zn (33.89 ppm), and Cu (77.23 ppm) are considered in the normal range, and Fe and Pb elements are high. Mineral levels of Ca, P, Cu, and Zn in grasses do not meet the daily requirements, whilst high levels of Fe and Mn minerals exceed the requirements for the spotted deer. The Pb content in grass is 0.94 ppm, which is within the normal limit. The levels of Ca (0.02%), Fe (308.11 ppm). and Mn (6.18 ppm) minerals in deer hair are high, however, zinc (44.68 ppm) and Cu (3.08 ppm) levels are low. High Pb level (14.38 ppm) is due to the long-term impact of Pb accumulation.

Tradicionalmente, el hidróxido de calcio (HC) era considerado el material de elección para el recubrimiento pulpar directo (RPD); pero esto ha cambiado con los años debido a las distintas desventajas que presenta. Los cementos a base de silicato de calcio (CSC) tienen propiedades ventajosas al compararlos con el HC como: bioactividad, biocompatibilidad, menor tiempo de fraguado, capacidad de sellado y resistencia, por lo que son usados en una variedad de procedimientos endodónticos, entre ellos el RPD. El presente artículo de revisión recopila información a partir de la búsqueda manual de artículos originales de investigación científica y revisiones de literatura de la base de datos de Medline/PubMed. Se describen las variedades de CSC, su mecanismo de acción, desventajas, factores relacionados y tasas de éxito clínico en su aplicación en casos de RPD.

Reconstrucción mandibular mediante colgajo miocutáneo de pectoral mayor en carcinoma epidermoide, reporte de caso clínico y revisión de la literatura.
Authors: Gallardo Caudillo Josué , Miranda Villasana José Ernesto , Plaza Garcia Eduardo
Published: April 2022

El carcinoma epidermoide surge del epitelio de la mucosa oral, es frecuente en la quinta y sexta décadas de la vida y está típicamente asociado con factores de riesgo como tabaquismo y el consumo de alcohol. En todo el mundo, la incidencia de cáncer oral es más alta en hombres que en mujeres. El incremento en la incidencia del cáncer en México requiere de un manejo adecuado, como colgajos vascularizados para reparar defectos generados por una hemimandibulectomía con márgenes de seguridad. A pesar de la llegada de injertos de tejido libres vascularizados, el colgajo pectoral mayor miocutáneo sigue siendo un colgajo pediculado ampliamente utilizado para la reconstrucción de defectos de tejidos blandos en la región oral y maxilofacial. Se muestra el protocolo quirúrgico realizado en el Hospital Regional “General Ignacio Zaragoza” ISSSTE para el tratamiento de un carcinoma epidermoide mandibular.
Stratigraphic and Geochemical Evidence for the Alteration of Calcareous Glauconitic Marine Sediments to Calcium Bentonite

Published: April 2022

Calcium bentonite mined in Smith County, Mississippi, has been reported in numerous publications to be derived from the weathering of volcanic ash. These interpretations were based on the bentonite having similar properties to bentonites actually formed from volcanic precursors. No recent detailed stratigraphic mapping in combination with modern laboratory analyses had been conducted for this area. Calcium bentonite, found at Olmstead, Illinois, in contrast, formed in situ from the weathering of biotite, glauconite, quartz, and other materials found in shallow calcareous marine deposits. Detailed stratigraphic mapping in Smith County in 2011 was carried out by Mississippi State University as part of a proposed surface reservoir study. The mapping, utilizing GPS and continuous sonic core samples, indicated that calcium bentonite was present and similarly formed by the in situ weathering of calcareous, glauconitic, marine marl in several formations in the Oligocene Vicksburg Group. The bentonite was not restricted to one stratigraphic interval as would be the case for a true ashfall deposit. Additional research conducted at Mississippi State University and more recently by others confirmed that the bentonite was formed by weathering and contemporaneous microbial action of the calcareous glauconitic marls. No volcanic ash was detected in any of the samples tested. The preponderance of other material present in the Smith County bentonite renders the presence of minute amounts of volcanic detritus volumetrically insignificant in the formation of the clay mass. A conceptual model is presented showing how the bentonite was formed and why it is restricted to this small area of the Oligocene outcrop.
Geomorphology, Three-Dimensional Geology, and Seismologic Hazards of the New Madrid Seismic Zone in Dyer County, Tennessee
Authors: Reichenbacher Renee , Van Arsdale Roy , Cox Randel , Cramer Chris
Published: April 2022

Geomorphic and three-dimensional geologic mapping reveals two major fault systems of the seismically active Reelfoot rift pass beneath Dyer County in northwestern Tennessee, the Reelfoot South fault, and the east-bounding faults of the Reelfoot rift. The Dyer County mapping also indicates that the two principal Reelfoot South fault hanging wall structures, the Lake County uplift and Tiptonville dome, pass beneath the county. Quaternary displacement was identified on southeastern Reelfoot rift margin faults in Dyer County, thus indicating that this rift margin has been active during the Quaternary from adjacent Obion County through Dyer County to Lauderdale County, Tennessee, for a distance of at least 60 km. The three-dimensional geologic mapping also provides stratigraphic thicknesses of surface sediment and underlying Paleogene and Cretaceous strata that significantly contribute to the estimation of ground motion in the event of a future large New Madrid seismic zone earthquake. The new ground motion maps using the three-dimensional geology of Dyer County are compared to the current U.S. Geological Survey earthquake hazard maps. This comparison reveals generally lower acceleration for buildings less than four stories high and greater acceleration for buildings greater than 10 stories high in the event of a large New Madrid seismic zone earthquake.

A thin layer with a lower velocity has been documented at the topmost outer core (Eʹ layer). However, the observation has been difficult to explain with a light element concentration change. Here, performing laser-heated diamond anvil cell experiment, we report the formation of FeHx and SiO2 from a reaction between water and FeSi alloy at the conditions relevant to the Earth’s core-mantle boundary (CMB). If water has been delivered to the CMB, this reaction could enable the exchange of hydrogen and silicon between the mantle and the core. As a result, a H-rich, Si-deficient layer formed at the topmost core would have a lower density, stabilizing the stratification, and a lower velocity, consistent with seismic studies. Therefore, the Eʹ layer may result from the deep transport of water to the CMB.

Microwave photonics (MWP) has adopted a number of important concepts and technologies over the recent pasts, including photonic integration, versatile programmability, and techniques for enhancing key radio frequency performance metrics such as the noise figure and the dynamic range. However, to date, these aspects have not been achieved simultaneously in a single circuit. Here, we demonstrate, for the first time, a multi-functional integrated microwave photonic circuit that enables on-chip programmable filtering functions while achieving record-high of >120 dB.Hz dynamic range and 15 dB of noise figure that are previously unreachable. We achieve this unique feature using versatile complex spectrum tailoring enabled by an all integrated modulation transformer and a double injection ring resonator as a multi-function optical filtering component. This work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of integrated MWP systems in real applications.
