Abstract
Immune-related cardiotoxicities are uncommon but potentially fatal. The study aims to evaluate the value of pacemakers and methylprednisolone pulse therapy (MPPT) to patients with immune-related myocarditis concomitant with complete heart block (CHB). We first reviewed medical records of three patients with immune-related myocarditis concomitant with CHB. For the pooled analysis, we searched related cases with immune-related myocarditis in the PubMed database and screened the patients. Clinical characteristics, management, and outcomes were summarized. Our three patients developed immune-related myocarditis concomitant with CHB about 2 weeks after receiving pembrolizumab, and were successfully treated with pacemaker implantation and high-dose steroids (two received MPPT). In the pooled analysis, 21 cases were eligible with an overall fatality rate of 52%. Patients with pacemakers had a fatality rate of 38%, significantly lower than patients without them (38% vs 100%; p = 0.035), particularly the MPPT subgroup (25% vs 100%; p = 0.019). All five patients without pacemakers expired. Among patients with pacemakers, MPPT patients tended to have an inferior rate compared with non-MPPT patients. Timely pacemaker implantation played a crucial role in improving the outcomes of patients with immune-related myocarditis concomitant with CHB. Patients receiving MPPT appeared to have a better prognosis. Additionally, multidisciplinary consultation should be recommended for better management.
Vocative, where do you hang out inwh-interrogatives?
Authors: López Laura González , Schmid Svenja 
Published: December 2022

AbstractThis paper provides new insights into the analysis of vocative structures that co-occur with a sentence by bridging two previously independent domains of linguistic research:wh-interrogatives and vocatives. More specifically, we investigate in which positions Spanish speakers accept vocatives inwh-interrogatives introduced by differentwh-phrases. The results of an acceptability judgment task indicate that our participants highly accept initial and final vocatives in allwh-interrogatives. For middle vocatives, the results differ acrosswh-phrases. While the participants accept middle vocatives inwh-interrogatives introduced bypor qué(‘why’) and d-linkedwh-phrases, they reject them in barewh-interrogatives. These findings require a modification of the syntactic analysis of vocatives. Initial vocatives are placed above ForceP, while middle and final vocatives are analyzed in two different positions, in an upper and a lower VocaddrP in the left periphery.

Kicau Mania is the mention of a group of songbird lovers. The existence of this group will lead to language registers for fluency in interacting within the group. The register is something that is very interesting to study in groups of songbird lovers in Boyolali because special terms often appear in communication between members of the group. The purpose of this study is to describe the form, meaning, and function of the registers for groups of songbird lovers or Kicau Mania in Boyolali district. This research is a qualitative descriptive study, the source of the data was obtained from the interaction of members of Kicau Mania and event activities in the form of speech from the Kicau Mania group in bird competitions and in bird markets. Methods of data acquisition through field observations and conducting interviews. The techniques applied are tapping, listening and speaking, recording, and taking notes. After obtaining the data, then analyze the data by identifying the data, classifying the data, processing the data and describing the results of the data analysis. This research produced several vocabulary registers, including resik (the mention of female canaries that are ready to mate), kuningan (the mention of young green cucak), kondangan (the mention of losing the competition). In addition, there are also new meanings and vocabulary such as, ngecuske (breeding birds), anggungan (mention of a type of bird that makes a soft voice and buzzes), banggelan (a reference to the term selling fast at a low price). The conclusion of this study is that several registers were found divided according to classification. forms of words and forms of noun phrases, adjectives, and verbs. Then, some meanings of each register vocabulary are obtained which are different from the registers of other language groups. Several special functions were obtained for registering Kicau Mania in Boyolali is heuristic function, informational function, imaginary function, instrumental function, personal function, and interaction function.

Published: December 2022

Abstract
There is an ever-increasing need for material systems to operate in the most extreme environments encountered in space exploration, energy production, and propulsion systems. To effectively design materials to reliably operate in extreme environments, we need an array of tools to both sustain lab-scale extreme conditions and then probe the materials properties across a variety of length and time scales. Within this article, we examine the state-of-the-art experimental systems for testing materials under extreme environments and highlight the limitations of these approaches. We focus on three areas: (1) extreme temperatures, (2) extreme mechanical testing, and (3) chemically hostile environments. Within these areas, we identify six opportunities for instrument and technique development that are poised to dramatically impact the further understanding and development of next-generation materials for extreme environments.

El Pacto Social ¿un concenso traslapante?
Authors: Lopera María Teresa 
Published: December 2022

A medida que avanzan las teorías liberales que buscan sustentar la legitimidad del Estado en el orden de lo político, surge inmediatamente el problema de sustentar la legitimidad del Estado en su tarea distributiva y en su accionar en el orden económico. Este artículo realiza un ejercicio reflexivo buscando analizar las propuestas del actual gobierno Samper, conocidas como el Salto y el Pacto social, a la luz del concepto “consenso traslapante” (solapante o sobrepuesto) de John Rawls precisando las novedades de esta concepción de política económica y de sus instrumentos.
Economía y constitución en Colombia
Authors: Restrepo Jairo Humberto 
Published: December 2022

En este artículo se presenta una lectura de la Constitución colombiana, de 1991, bajo una perspectiva económica. La lectura es realizada siguiendo un enfoque descriptivo y teniendo en cuenta cuatro materias básicas en las cuales se clasifica el contenido de la constitución, seleccionado para tal fin: desarrollo económico, aspectos macroeconómicos, aspectos microeconómicos y ordenamiento territorial. En general, se encuentra que los asuntos económicos generan un espacio considerable en la Constitución. Además, en el artículo se considera un seguimiento sobre el desarrollo legal y práctico de los dos aspectos que constituyeron las principales reformas económicas, con un gran acento institucional, y los mismos que se encuentran actualmente en el centro del debate, propiciado por el gobierno actual del presidente Samper, para modificar la Constitución. Se trata de la banca central y el federalismo fiscal y este debate permite sugerir que el caso colombiano constituye una buena evidencia empírica acerca de los problemas de acción colectiva.
El efecto colegio sobre la variabilidad del rendimiento en matemáticas
Authors: Castaño Elkin 
Published: December 2022

En estudios de educación, es de gran interés tratar de determinar la importancia que tienen las características propias de los colegios sobre el rendimiento que obtienen sus estudiantes. En otras palabras, los investigadores quieren saber qué porcentaje de la variabilidad del rendimiento es explicado por el “efecto colegio”. Desafortunadamente, en la mayoría de los estudios realizados hasta ahora, esta pregunta ha quedado sin respuesta debido a que las técnicas usadas, como la regresión lineal estándar, no permiten descomponer la variabilidad del rendimiento entre la variabilidad explicada por las características propias de los estudiantes y la explicada por las características de los colegios. Dichas técnicas fallan al no reconocer que en estos casos los datos son generados por estructuras jerárquicas, es decir los datos son observados en diferentes niveles: generalmente se tiene variables que describen los individuos, y los individuos están agrupados en unidades más grandes de las cuáles también se tienen variables que las describen. Este trabajo ilustra como el uso de los modelos jerárquicos lineales (Mason, Wong y Entwistle, 1983; Bryck y Raundenbush, 1992) sobre la Encuesta Saber 93, permite concluir que aproximadamente el 29% de la varianza del rendimiento en matemáticas de los estudiantes de tercero de primaria es explicada por el efecto colegio. Palabras Clave: Regresión lineal, modelos jerárquicos, efecto colegio, efectos aleatorios, rendimiento en matemáticas.

Indicadores: la intervención reguladora en la industria eléctrica colombiana
Authors: Tobón David , Valencia Germán , Castillo Gustavo 
Published: December 2022

El objetivo de este artículo es presentar un análisis estadístico de la calidad de la regulación de la industria eléctrica colombiana, basados en una clasificación económica de las resoluciones emitidas por la Comisión de Regulación de Energía y gas Creg. Aquí se entiende la regulación como una relación contractual entre distintos grupos de interés, cada uno con objetivos particulares, y la calidad de la regulación como el ejercicio de la independencia y la autonomía bajo mecanismos adecuados de control de gestión y resultados. El análisis concluye, por un lado, que la mayor cantidad de resoluciones cumple con el principio orientador de regular la conducta de los agentes, aunque la inestabilidad y los temas administrativos ocupan una destacada posición en esta normatividad; por toro, que no hay percepción en los agentes sobre corrupción aunque si admiten la posibilidad de la existencia de influencia sobre el marco regulador. Con base en los resultados se recomiendan cambios que mejorarán la gestión de la Creg.Palabras clave: industria eléctrica, grupos de interés, calidad de la regulación, corrupción, captura, influencia.

A Real-Time and Data-Driven Ground-Motion Prediction Framework for Earthquake Early Warning
Authors: Chatterjee Avigyan , Igonin Nadine , Trugman Daniel T. 
Published: December 2022

ABSTRACTThe ShakeAlert earthquake early warning system in the western United States characterizes earthquake source locations and magnitudes in real time, issuing public alerts for areas where predicted ground-motion intensities exceed a threshold value. Although rapid source characterization methods have attracted significant scientific attention in recent years, the ground-motion models used by ShakeAlert have received notably less. This study develops a data-driven framework for earthquake early warning-specific ground-motion models by precomputing and incorporating site-specific corrections, while using a Bayesian approach to estimate event-specific corrections in real time. The study involves analyzing a quality-controlled set of more than 420,000 seismic recordings from 1389 M 3–7 events in the state of California, from 2011 to 2022. We first compare the observed ground motions to predictions from existing ground-motion models, namely the modified Boore and Atkinson (2008) and active crustal Next Generation Attenuation (NGA)-West2 ground-motion prediction equations, before implementing a new Bayesian model optimized for a real-time setting. Residual analysis of peak ground acceleration and peak ground velocity metrics across a host of earthquake rupture scenarios from the two ground-motion models show that the active crustal NGA-West2 model is better suited for ShakeAlert in California. In addition, the event-terms calculated using our Bayesian approach rapidly converge such that errors from earthquake magnitude estimation can be corrected for when forecasting shaking intensity in real time. Equipped with these improved ground-shaking predictions, we show that refined ShakeAlert warnings could be issued to the public within as soon as 5 s following ShakeAlert’s initial warning. This approach could be used both to reduce prediction uncertainties and thus improve ShakeAlert’s alerting decision.
A new fractal approach to the clustering of earthquakes: Physical fractal
Authors: Chen Yong , Chen Ling , Liu Zhaojun , Wu Ru-Shan 
Published: December 2022

Abstract
Traditional fractal analysis methods of earthquake temporal clustering treat earthquake events as mathematical points (without mass) in time (Smalley et al., 1987). The results obtained by these methods mainly reflect the seismic behavior of numerous small earthquakes. A sieve method of physical fractal analysis has been developed in the present article in which a series of magnitude sieves are used to study the fractal behavior of earthquakes with different magnitudes. Fractal analyses of earthquake clustering are conducted for three regions: northern China, mainland of China, and southern California. We find that all the earthquake subsets of each region show nearly the same fractal dimension, D = 0.3 for northern China and the mainland of China and D = 0.4 for southern California. The scaling ranges in which the corresponding earthquake subsets under consideration exhibit fractal features vary from subset to subset. The method has the potential application to characterizing the fractal behavior of earthquake clustering for different regions.
Recording teleseisms on the seafloor; an example from the Juan de Fuca plate
Authors: Lewis Brian T. R. , Dorman LeRoy M. 
Published: December 2022

Abstract
In 1991, during an experiment to compare low-frequency seismic noise on a basaltic and a sediment covered seafloor (NOBS), we recorded teleseisms on the Juan de Fuca ridge, the Gorda ridge, and the adjacent Cascadia Basin with the SNAG ocean-bottom seismometers (OBS). These data provide an indication of the type of data that may be obtained from future experiments to record teleseisms and may be helpful in designing these experiments and analyzing the results.
We found that although seafloor noise is dominated by microseisms in the band 0.1 to 0.3 Hz, there is a well-developed minimum in noise from about 0.03 to 0.1 Hz (the noise notch). In this noise notch, teleseisms can be most easily detected. In the Cascadia area, the overall noise levels are such that only teleseismic events with magnitude greater than 6.5 were usefully recorded. A magnitude 6.6 event in the New Britain area (Δ = 89°) produced usable P- and surface-wave data only in this noise notch.
In the band 0.03 to 0.1 Hz, the character of compressional waves is very sensitive to water depth and the type of sensor. We show that pressure sensors are especially sensitive to reverberation in the ocean and that motion sensors (seismometers) are less sensitive to ocean reverberations and will record teleseismic phases with less distortion than pressure sensors.
The Cascadia data indicate enhanced P amplitudes at sites on the ridge axes that could be due to focusing caused by a low-velocity lens. These data suggest that amplitude information may be as, or even more, useful than P delay times for determining upper mantle structure.

Published: December 2022

AbstractWe employ seismic reflection, magnetics, and electromagnetics to locate precisely the southern extension of the Pahrump Valley Fault Zone (PVFZ) and examine its subsurface geometry. The southern extension of the PVFZ is active and represents a potential seismic hazard for Las Vegas. We observe pronounced magnetic and conductivity anomalies, and truncations of reflectors in the seismic profiles coincident with one of three Holocene scarps in southern Pahrump Valley. These geophysical techniques in combination can locate faults more precisely than the presence of eroded scarps.
Pseudo green's functions and waveform tomography
Authors: Song Xi J. , Helmberger Donald V. 
Published: December 2022

AbstractRetrieving source characteristics for moderate-sized earthquakes in sparsely instrumented regions has been made possible in recent years, through the modeling of waveforms at regional distances. The techniques used in such studies model waveforms successfully at long period, using Green's functions for simple 1D crustal models. For small earthquakes (M &lt; 4), however, long-period signals are usually noisy, and modeling short-period waveforms requires refined Green's functions such as used in the empirical Green's function (eGf) approach. In this article, we present a new technique that generates such Green's functions by perturbing individual generalized ray responses calculated from a 1D model. The model is divided into blocks, and velocities in the blocks are allowed to vary, which shifts the arrival time of the individual rays similar to conventional tomography. The amplitudes of the rays are perturbed independently to accommodate local velocity variations in the structure. For moderate-sized earthquakes with known source mechanism and time history, the velocity variation in each block and the amplification factor for individual rays can be optimized using a simulated annealing algorithm. The resulting modified Green's functions, pseudo Green's functions (pGfs), can be used to study the relative location and characteristics of neighboring events. The method is also useful in retrieving 2D structure, which is essentially waveform tomography.
