Determination of annual rainfall in north-east India using deterministic, geospatial, and machine learning techniques
Authors: Agarwal Shivam , Mukherjee Disha , Debbarma Nilotpal
Published: November 2023

Analysis of extreme annual rainfall in the six north-east Indian states of Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura using the deterministic interpolation technique of inverse distance weighting (IDW), the geospatial interpolation technique of Ordinary Kriging (OK) and the machine learning prediction technique of generalised additive model (GAM). GAM is used only for prediction and hence the results are then subsequently interpolated by OK to create the rainfall maps. The datasets considered for this study are a training dataset of 171 points which consisted of satellite rainfall and a testing dataset with ground rain gauge data of 33 points which was used for validation of the former. A combined dataset of training + testing was also interpolated and mapped to compare for visual accuracy of each technique. It was seen that OK was a superior and a much more realistic interpolation technique than IDW, since it took the altitude of each site into consideration along with latitude and longitude, unlike IDW, which only interpolated over the x–y plane and didn't rely on altitude. When the predictions of the training dataset through GAM were mapped using OK, it showed almost parallel contours, which is undesirable for natural phenomenon like rain.

Para a medicina transdisciplinar as dimensões da existência humana estão interrelacionadas e as manifestações da doença e da saúde acontecem em uma cascata, dos níveis mais sutis para os mais densos (supramental/espiritual; mental/emocional, vital, e manifestando, por último, no metabólico/físico). Assim, o movimento de resgate do Sagrado em Mim/ Sagrado Feminino tem chamado à atenção de muitas mulheres em todo o mundo para a necessidade de olhar para si, para além da dimensão física, e resgatar a sua identidade individual e coletiva, como princípio basilar da saúde. Este estudo ancora-se na pesquisa descritiva, do tipo relato de experiência. Tendo como objetivo principal, relatar a experiência vivenciada por integrantes da equipe executora na condução do projeto de extensão.

Oxidative Stress in Beta-thalassemia Patients: Role of Enzymatic and Non-enzymatic Modulators
Authors: Fatima Tehseen , Khan Sadaf , Khan Muhammad Mubashir , Kamran Rameesha , Uddin Muhammed Wajih , Sohrab Saba
Published: November 2023

Background:

Oxidative stress is a pathophysiological state that arises due to an imbalance created between ROS generation and the antioxidant potential of the host cell. Transfusion- dependent beta-thalassemia major patients are at high risk of cellular and molecular damages induced by ROS mainly due to iron overload caused by repetitive blood transfusion.

Objectives:

To analyze oxidative stress status levels in β-thalassemia patients. To analyze the expression profile of enzymatic (NOS2, OGG1, HuR, SOD2) and non-enzymatic (VDR) redox regulators in β-thalassemia patients. To assess polymorphism in VDR (rs2228570) and NOS2 (rs944725) in β-thalassemia patients. To analyze serum vitamin D levels of β-TM patients compared to healthy individuals.

Methods:

The present case-control study aimed to identify Vitamin D levels in the serum of β-thalassemia patients and compared it with healthy subjects. The study further analyzed VDR FOKI (rs2228570) polymorphism through ARMS-PCR. Expression profiling of VDR, anti-oxidant enzyme (SOD2 and GPx), and their respective regulator (HuR and NrF2) transcripts was done by the 2–ΔΔCt method.

Results:

The study reports that there is no a significant difference between the Vitamin D levels among healthy and patients. VDR polymorphism analysis (rs2228570) demonstrates that although the C allele is prevalent in the study cohort, the frequency of the T allele is comparatively higher in β-thalassemia patients as compared to healthy subjects. Furthermore, patients express lower levels of anti-oxidant enzymes despite having increased oxidative stress.

Conclusion:

The study reports that β-thalassemia patients are at higher risk of cellular and molecular damages induced by oxidative stress and their associated pathologies inefficient enzymatic and non-enzymatic anti-oxidant defense systems.

Authors: da Silva Honório Thiago , Simon Alice , Clacino Machado Raiane Monteiro , Rodrigues Carlos Rangel , do Carmo Flávia Almada , Cabral Lucio Mendes , de Sousa Valeria Pereira
Published: November 2023

Background:

Oral suspensions are heterogeneous disperse systems, and the particle size distribution,
crystalline form of the dispersed solid, and composition of the formulation can be listed as parameters
that control the drug dissolution rate and its bioavailability.

Objective:

The aim of this work was to develop a discriminative dissolution test, which, in association with in
silico methodologies, can make it possible to safely anticipate bioavailability problems.

Methods:

Nimesulide and ibuprofen (BCS class II) and cephalexin (BCS class I) oral suspensions were
studied. Previously, solid-state structure and particle size in active pharmaceutical ingredients were characterized
and the impact of differences on solubility was evaluated for the choice of discriminative medium. Afterwards,
particle size distribution (0.1 to 360 μm), dissolution profile, and in vitro permeability in Caco-2 cell of
commercial suspensions, were determined. These parameters were used as input for the establishment of the in
vitro-in vivo correlation (IVIVC) for the suspensions using the GastroPlus™ with Wagner-Nelson and Loo-
Riegelmann deconvolution approach.

Results:

The predicted/observed pharmacokinetic model showed good correlation coefficients (r) of 0.960,
0.950, and 0.901, respectively. The IVIVC was established for one nimesulide and two ibuprofen suspensions
with r between 0.956 and 0.932, and the percent prediction error (%PE) did not exceed 15%.

Conclusion:

In this work, we have performed a complete study combining in vitro/in silico approaches with
the aim of anticipating the safety and efficacy of oral pharmaceutical suspensions in order to provide a regulatory
tool for this category of products in a faster and more economical way.

Published: November 2023

Background:

Herba Epimedii, a commonly used traditional herb, has been proven
effective in ameliorating osteoporosis. However, the active ingredients and potential mechanism
need further exploration.

Objective:

To screen active ingredients of Herba Epimedii with the effect of ameliorating osteoporosis
and to explore their potential mechanisms.

Methods:

TCMSP and Swiss Target Prediction were applied to collect the ingredients of Herba
Epimedii and their targets. UniProt, GeneCards, TTD, DisGeNET, and OMIM were adopted to
search osteoporosis-related genes. STRING and DAVID were used to perform enrichment analysis.
Effects of screened ingredients were evaluated on MC3T3-E1 cells and RAW264.7 cells,
respectively.

Results:

Eleven ingredients were screened by Network Pharmacology. They exerted a promoting
effect on MC3T3-E1 cells (10-9-10-5 M). The ingredients didn’t significantly affect ALP activity
and osteoblastogenesis-related genes. Baohuoside 1, Sagittatoside B, Chlorogenic acid,
Cryptochlorogenic acid, and Neochlorogenic acid significantly increased calcium depositions.
The ingredients didn’t exhibit a dose-dependent inhibition or promotion on RAW264.7 cells.
Baohuoside 1, Sagittatoside B, Neochlorogenic acid, Cryptochlorogenic acid, Icariin, Epimedin
A, Chlorogenic acid, Sagittatoside A, and Epimedin C suppressed the level of TRACP. Baohuoside
1, Sagittatoside B, Cryptochlorogenic acid, Neochlorogenic acid, Chlorogenic acid, Sagittatoside
A, and Icariin decreased the number of multinucleated osteoclastic cells. Baohuoside 1,
Sagittatoside B, and Cryptochlorogenic acid could significantly inhibit MMP-9 expression.

Conclusion:

Neochlorogenic acid, Sagittatoside B, Chlorogenic acid, and Cryptochlorogenic acid
promoted MC3T3-E1 differentiation, among which Neochlorogenic acid showed significant
promotion in viability, mineralization, and OPN expression. Baohuoside 1, Sagittatoside B,
Cryptochlorogenic acid, Neochlorogenic acid, Chlorogenic acid, and Icariin inhibited
RAW264.7 differentiation, among which Baohuoside 1 showed significant inhibition on
TRACP, multinucleated osteoclastic cells number and MPP-9 expression. The mechanism might
relate to the FoxO signaling pathway, MAPK signaling pathway, and TNF signaling pathway.

Authors: Zhang Xiaoli , Zhao Yalei , Liu Liangru , He Yingli
Published: November 2023

Syndecan-1 (SDC-1), known as a coreceptor of various growth factors or an integrin
binding partner, regulates various cell behaviours. Under certain pathological conditions, SDC-1
is shed from the cell surface and plays a protective or pathogenic role in various diseases. In the
liver, SDC-1 is highly expressed in hepatocytes, where it is localized on the basolateral surface. It
is critical to the cellular and molecular functions of hepatocytes, including their attachment to hepatitis
viruses. Previous studies have reported that SDC-1 may function as a novel and promising diagnostic
and therapeutic marker for various liver diseases, such as drug-induced liver injury, liver
fibrosis, and liver cancer. In this review, we summarize related research and highlight the mechanisms
by which SDC-1 participates in the pathogenesis of liver diseases, as well as its potential
diagnostic and therapeutic applications. This review is expected to lay the foundation for further
therapeutic strategies to target SDC-1 in liver diseases.

Authors: Anandaraj A. , Alphonse P.J.A.
Published: November 2023

Background:

Epilepsy is a neurological disorder that leads to seizures. This occurs due
to excessive electrical discharge by the brain cells. An effective seizure prediction model can aid
in improving the lifestyle of epilepsy patients. After analyzing various patents related to seizure
prediction, it is observed that monitoring electroencephalography (EEG) signals of epileptic patients
is an important task for the early diagnosis of seizures.

Objective:

The main objective of this paper is to assist epileptic patients to enhance their way of
living by predicting the seizure in advance.

Methods:

This paper builds a feature augmentation-based multi-model ensemble-based architecture
for seizure prediction. The proposed technique is divided into 2 broad categories; feature
augmentation and ensemble modeling. The feature augmentation process builds temporal features
while the multi-model ensemble has been designed to handle the high complexity levels of the
EEG data. The first phase of the multi-model ensemble has been designed with heterogeneous
classifier models. The second phase is based on the prediction results obtained from the first
phase. Experiments were performed using the seizure prediction dataset from the University Hospital
of Bonn.

Results:

Comparison indicates 98.7% accuracy, with improvement of 5% from the existing model.
High prediction levels indicate that the model is highly capable of providing accurate seizure
predictions, hence ensuring its applicability in real time.

Conclusion:

The result of this paper has been compared with existing methods of predicting seizures
and it indicated that the proposed model has better enhancement in the accuracy levels.

Authors: Yuvaraj Thangaraj , Suresh Thirukoilur Dhandapani , Joly Maheswaran , Balamurugan Pottukkannan , Babu Nudhurupati Venkata Phanendra
Published: November 2023

Background:

This article presents a novel strategy that utilizes the nature-inspired
Spotted Hyena Optimizer Algorithm (SHOA) to optimize the placement of solar and wind-based
renewable distributed generation (RDG) and distribution static compensators (DSTATCOMs) in
radial distribution systems (RDS).

Methods:

The proposed technique aims to determine the optimal locations of DSTATCOM and
RDGs based on the loss sensitivity factor (LSF), while the appropriate sizes are determined using
the newly developed SHOA. To facilitate efficient load flow calculations, a fast and effective
backward/forward sweep algorithm (BFSA) is employed.

Results:

The primary objective of this method is to minimize overall power losses within the system.
The effectiveness of the optimization approach based on SHOA is demonstrated through extensive
simulations conducted on a standard IEEE 33-bus test system with diverse load models.

Conclusion:

The results of the simulations and comparisons of multiple case studies clearly indicate
that the allocation of DSTATCOMs leads to significant reductions in power losses and improvements
in voltage profiles.

Published: November 2023

En este articulo se presentan los resultados de las investigaciones llevadas a cabo por la Universidad Nacional de Ingeniería para generar electricidad, a partir del biogás, con la finalidad de electrificar poblaciones nativas ubicadas en la región del Alto Marañón en el Departamento de Amazonas. El com-bustible necesario se obtuvo de una planta piloto de biogás, tipo Olade-Guatemala de 5m³/dia, del antiguo Instituto de Investigación Tecnológica Industrial y de Normas Técnicas, ITINTEC, recuperada en la Unidad del Servicio Nacional de Adiestramiento en Trabajo Industrial, SENATI, de Villa El Salvador. El motor de biogás se logró a partir de una innovación en un grupo estacionario gasolinero Honda,que cuenta con un motor monocilindrico y genera 3,5 kVA. La innovación consiste en un carburador, de muy bajo costo, que permite introducir el biogás al motor para su posterior combustión en éste. Con este dispositivo, que no existe en el mercado local, se ha logrado un rendimiento de 1,38 m³ de biogas/ (kWh) de electricidad generada en el grupo ensayado, y se puede aplicar en grupos de este tipo, que llegan hasta 8,0 kW. Estos resultados permitirán la electrificación de pequeños centros poblados, como los observados en el Alto Marañón, u otros como los requeridos por la actividad productiva o de servicios, como es el caso de la crianza de especies menores y mayores, o la hotelería.

Authors: Gutarra Espinoza Abel , Gabriel Tuesta Erika , Veliz Katia , Sun Kou Maria del Rosario
Published: November 2023

En este trabajo se presentan los resultados del tratamiento de efluentes textiles aplicando sucesivamente la adsorción de los colorantes sobre arcilla activada y luego la irradiación UV/ TiO, (fotocatálisis), a la solución remanente. La arcilla natural utilizada proviene de la provincia de Huancayo, Región Junín. Después de purificada, se determinó por difracción y fluorescencia de rayos X que tenía un alto porcentaje de montmorillonita. Los colorantesutilizados para la prueba de adsorción fueron del tipo directos azoicos, denominados rojo 80 y azul 71. Ambos colorantes se usan frecuentemente en la producción de textiles. La activación ácida consistió en la disolución parcial de la arcilla en medio ácido (HCI 2N) a 90°C en un sistema de reflujo. Los cambios estructurales y de composición fueron seguidos por DRX, FRX y SEM. Los resultados mostraron que la arcilla activada puede incrementar su capacidad de adsorción de colorantes textiles en 30 veces respecto a la arcilla natural, alcanzando el equilibrio entre 10-15 min. En esta etapa, se bajó la concentración de colorante azul desde 90 a 15 ppm en un reactor de IL de capacidad con 1 g de arcilla. Después de la adsorción seseparó la arcilla, se agregó TiO, y se irradió el sistema coloidal con luz ultravioleta (UV), En esta segunda etapa, el colorante remanente se degrada más lentamente hasta llevar la concentración final de colorante a menos de 1 ppm.

Published: November 2023

The success of software development projects is often hindered by time pressure (TP), leading to decreased productivity, compromised quality, and increased risk of failure. To address this issue, it is crucial to understand the key factors contributing to TP in software development projects. In line with the study's objectives, the review methodology followed the Kitchenham and Charters criteria, and a search strategy encompassed four primary digital databases, namely IEEE, ACM Digital Library, Science Direct, and Springers, resulting in 4,500 relevant sources. After applying inclusion and exclusion criteria, a total of 128 papers were selected for analysis. This paper offers a comprehensive overview of the factors contributing to TP in software development. This study synthesizes the findings from multiple studies to guide practitioners in improving their project management approaches and highlights the significance of enhancing various aspects of the development process. The findings highlight the importance of improving project management, estimation techniques, knowledge, and skills to effectively manage TP. Additionally, managing requirements volatility, setting clear goals and objectives, and reducing distractions and interruptions emerge as crucial strategies for mitigating TP and enhancing project success. Furthermore, selecting software developers based on their personality traits is recommended to foster a work environment conducive to reduced TP and improved software development outcomes. By understanding and addressing these factors, software development teams can alleviate TP and increase the likelihood of successful software products. Implementing these recommendations can contribute to reduced TP, improved project outcomes, and enhanced overall success in software development.
A Comparison of Conventional Intervention and Home-based Approach with Head-mounted Device for Cervical Spondylotic Myelopathy after Surgery: Quasi-Experimental Retrospective Study (Preprint)
Authors: Yen Ling-Wei , Chen Hung-Bin , Rezaei Asghar , Lien Hen-Yu , Cheng Chih-Hsiu
Published: November 2023

BACKGROUND

Cervical spondylotic myelopathy (CSM) is a degenerative disease affecting cervical spinal cord function and becoming more prevalent in the aging population. Exercise intervention has shown to be beneficial, but adherence to conventional programs can be poor.

OBJECTIVE

This study aimed to compare the effects of conventional intervention and home-based intervention using a head-mounted device on patients with CSM.

METHODS

This quasi-experimental retrospective study was conducted from 2014 to 2018. The head control performance of 75 subjects with CSM, 36 of whom received a conventional exercise intervention and 39 of whom received a home-based exercise intervention, was evaluated before surgery, three months after surgery, and after completing an eight-week exercise intervention. The two-way mixed ANOVA was used to explore the main effects and interactions between two groups and three time points, with statistical significance at P≤.05.

RESULTS

Both groups showed improvements in the numerical rating scale (P=.003), neck disability index (P=.001), and range of motion (ROM) in neck flexion (P<.001) and extension (P<.001) after exercise, but the home-based group exhibited significantly greater ROM in left and right rotation (P<.001 and P=.011) and greater muscle strength in neck flexors (P<.001) and extensors (P<.001) compared to the conventional group. Both groups had lower muscle activation in the sternocleidomastoid (P<.05) and splenius capitis (P<.05) muscles during movements after exercise, while the home-based group exhibited lower reposition errors (P<0.001 for variable error during flexion and P=0.003 for root mean square error during right rotation) after exercise.

CONCLUSIONS

The home-based exercise group demonstrated better outcomes in cervical mobility, neck muscular strength, and proprioception after exercise intervention, even surpassing pre-surgery levels, compared to the conventional group. These findings suggest that home-based exercise intervention using head-mounted device may offer advantages over conventional intervention for individuals with CSM.

La inserción de Estados Unidos y China en la cadena global de valor de semiconductores, ¿y México?
Authors: Ortiz Velásquez Samuel , Jiménez Chalico Danitza
Published: November 2023

El artículo examina el funcionamiento de la industria de semiconductores en el siglo XXI y discute diferentes instrumentos de política industrial adoptados por Estados Unidos y China para avanzar a una cadena resiliente y geográficamente próxima, ello ante la disputa tecnológica entre ambos países profundizada con la crisis sanitaria de 2020. Se reflexiona sobre el papel que jugará México en dicha reconfiguración. Se partió del marco analítico de las Cadenas globales de valor y de desarrollos conceptuales recientes de política industrial. Se concluye que la cadena presenta predominantemente una gobernanza relacional, altas barreras a la entrada y concentración; la elevada interdependencia y especialización genera una colaboración entre empresas globales con sede en Estados Unidos y Asia. El acopamiento estratégico en América del Norte impulsado por Estados Unidos profundizará la inserción de México en ensamble, ello ante la crisis de la manufactura desde 2000 y la falta de políticas industriales activas.
Contención migratoria en la frontera norte de méxico: Detenciones y deportaciones de centroamericanos durante la pandemia
Authors: Castillo Ramírez Guillermo
Published: November 2023

Los centroamericanos irregularizados en tránsito por México y con destino a Estados Unidos de América (EUA) son poblaciones que experimentan la contención migratoria de los gobiernos estadounidense y mexicano. Durante la pandemia del Sars-Cov2 (2020-2021) y en el contexto de la frontera norte mexicana, este artículo, mediante la consulta de fuentes oficiales e informes de organizaciones promigrantes, argumenta que hubo cambios espaciales y sociodemográficos en los procesos de detención y deportación de migrantes centroamericanos. Se sostiene que, más allá de ser sólo ejercicios de la ley mexicana migratoria sobre poblaciones extranjeras, las detenciones y deportaciones constituyen parte central de las estrategias de contención migratoria nacional y regional, en el marco de la agenda antiinmigrante estadounidense. El aporte del trabajo es mostrar que la frontera norte, en su condición de territorio de concentración de detenciones y deportaciones, funge como un espacio nacional y regional de desarticulación de migraciones centroamericanas.

Las fuentes de energía renovable en Nova Scotia: Estrategias del gobierno provincial frente a las presiones del gobierno federal canadiense para alcanzar su meta de cero emisiones para 2050
Authors: Santín Oliver , Fridell Gavin
Published: November 2023

El gobierno federal canadiense bajo la administración del primer ministro liberal Justin Trudeau, estableció en 2021 su compromiso para que Canadá comenzara una reducción gradual de sus emisiones contaminantes hasta llegar a cero en 2050. Tal directriz, significa que las diez provincias y tres territorios del país, deben ajustar de forma autónoma sus estrategias para sumarse a esa meta en un ejercicio común establecido desde el gobierno central. Para el caso particular de la provincia atlántica de Nova Scotia, este mandato federal representa un enorme reto, ya que su infraestructura, desarrollada desde el siglo XVII, giró en buena medida alrededor de la generación de energía fósil. Este trabajo señala los obstáculos culturales y corporativos, las potencialidades de la energía alternativa, y las estrategias políticas que han debido desarrollar los líderes de la provincia para encontrar la estrategia más adecuada que sume a Nova Scotia a la dinámica que ya se ha emprendido en todas las regiones del país.
Terrorismo íntimo: violencia de pareja, feminicidio y confinamiento
Authors: Ascensio Martínez Christian
Published: November 2023

La violencia de pareja genera altos niveles de daño físico, emocional y económico. En especial en el caso de las mujeres, esta violencia se asocia con problemas de salud diversos, dificultades económicas, encarcelamientos y uso de sustancias. Aunque los datos no suelen reflejar la incidencia real de este fenómeno, es sabido que una alta proporción de las víctimas teme reportar las agresiones o buscar atención médica, sea por las represalias de la pareja, sea por la revictimización de las autoridades. Tal situación parece haberse agravado durante el periodo de confinamiento asociado a la pandemia de COVID-19, como consecuencia del aislamiento forzado y la restricción de movilidad en los espacios públicos. Este artículo explora algunas dimensiones de la violencia de pareja que permiten concebirle como equiparable a una estrategia terrorista que genera numerosos riesgos y afecta la vida de millones de mujeres en el mundo, pero principalmente en la región latinoamericana.
Sociología del temor al delito en la pandemia: ¿Qué ocurrió en los hogares mexicanos?
Authors: Jasso López Lucía Carmina
Published: November 2023

Desde la Sociología del temor al delito se estudia cómo cambió la percepción de inseguridad en los hogares mexicanos en el contexto de la pandemia por COVID-19. A partir de las encuestas de victimización urbana se analiza la transformación de esta percepción en México durante 2020. Se encuentra que contrario a lo esperado por la literatura, esta percepción disminuyó, por lo que se plantean las preguntas: ¿Qué ocurrió en los hogares mexicanos? ¿Por qué se redujo la percepción de inseguridad durante la pandemia por COVID-19?

Para explicar este cambio se exploran variables criminológicas relacionadas a la percepción de inseguridad como el robo a casa habitación y la inversión en medidas de seguridad para tornar las viviendas más seguras. Paralelamente se indagan otras variables asociadas al aislamiento social y el repliegue de la población a las casas que, como efecto de la pandemia, cambiaron la vida en sociedad a nivel global. Se concluye que en este contexto, los hogares se posicionaron como espacios centrales para ejercer el derecho a quedarse en casa y evitar el contagio, y además se resignificaron en el imaginario social.
Analysis and Prediction of Earthquake Impact using Convolutional Neural Networks
Authors: S Siddharth
Published: November 2023

Abstract: Earthquake prediction is a complex yet crucial area of study, holding the potential to safeguard lives and minimize the catastrophic impact of seismic events. Convolutional Neural Networks (CNNs), originally designed for image analysis, have demonstrated their adaptability in geoscience, particularly in the domain of earthquake prediction. Leveraging CNNs in earthquake prediction entails the examination of extensive seismic datasets, encompassing waveform records, sensor data, and geospatial information. CNNs excel in automatically detecting intricate patterns and associations within these datasets, rendering them a suitable choice for identifying early seismic indicators and anomalies. The process of employing CNNs for earthquake prediction comprises several essential stages, including data preprocessing, feature extraction, and model training. Researchers often initiate data preprocessing to eliminate noise and enhance data integrity. Subsequently, CNNs are deployed to extract pertinent features from the data, capturing nuanced patterns that may suggest impending seismic activity. These features can encompass spectral attributes, temporal fluctuations, or spatial dependencies, all of which are then incorporated into a CNN-based model. Convolutional Neural Networks have emerged as a promising tool in the realm of earthquake prediction. Their proficiency in scrutinizing seismic data and uncovering subtle patterns holds great potential for enhancing early warning systems and earthquake risk assessment. This, in turn, can significantly contribute to disaster preparedness and mitigation efforts.

Authors: Hans Vinay , Bhaskar Dr. M. K.
Published: November 2023

bstract: The increasing demand of load without considerable increase in transmission resources has posed numerous constraints and challenges in the power system monitoring and performance. Modern power system grid monitoring tools use data from remote terminal units (RTUs), protective relays, and transducers to provide information to system operators. This information is vital for the operation of the power system on a daily basis and under system contingencies. However, the method presently available to retrieve data from the devices is asynchronous and relatively slow. The asynchronous nature of the data does not provide accurate angle difference information from two nodes on the network. Moreover, the low data rate may be too slow to capture many short-duration disturbances on the grid. Alternatively, Synchrophasors based technology can be used to provide high-speed and coherent real-time information of the power system that is not available from legacy supervisory control and data acquisition (SCADA) systems.

En 1921 se celebró una subasta de antigüedades en Nueva York en la que se vendió un retablo de pequeño formato que pudo pertenecer a una capilla u oratorio privado. Un siglo después, en 2020, esta pieza ha sido adquirida por el Grupo Jorge y en la actualidad forma parte de su colección de arte medieval en Zaragoza. En este trabajo se ha reconstruido el periplo de esta pieza desde que salió de España en 1921 hasta la actualidad y, además gracias a una fotografía antigua, hemos podido identificar que este retablo perteneció a un personaje cercano al arzobispo Domingo Ram.

Accurate short-term forecasting of carryover storage is crucial for
effective reservoir management and water resource decision-making.
Real-time information plays a vital role in reservoir operation
decisions, highlighting the need to incorporate such information in
carryover storage forecasting. In this study, we propose a dynamic
prediction model (DPM) that integrates static and dynamic factors,
including runoff forecasting, real-time water level, and remaining time
from carryover level, to improve short-term reservoir operation. The
model is applied to three reservoirs in China, and its performance is
evaluated using statistical measures. The results demonstrate that the
DPM surpasses the traditional static prediction model, yielding enhanced
accuracy in reservoir carryover storage prediction. The inclusion of
weakly correlated real-time information contributes to the improvement
of forecasting accuracy. Moreover, we observe variations in the
importance of dynamic factor combinations across different seasons.
Notably, in the wet season, the combination of runoff forecasting and
real-time water level factors significantly enhances forecast accuracy.
This study highlights the potential of employing DPMs that incorporate
real-time information for short-term reservoir operation, leading to
improved reservoir management and decision-making. The findings
emphasize the importance of considering real-time information and
seasonality in carryover storage forecasting, thereby facilitating more
effective water resource utilization and reducing the risks associated
with floods and droughts.

Aim The Arctic ecosystems are exposed to amplified climate warming and,
in some regions, to rapidly developing economic activities. This study
assesses, models and maps the geographic patterns of community-level
plant species richness in the Western Siberian Arctic and estimates the
relative impact of environmental and anthropogenic factors driving these
patterns. With our study, we aim at contributing towards conservation
efforts for Arctic plant diversity. Location Western Siberian Arctic,
Russia. Methods We investigated the relative importance of environmental
and anthropogenic predictors of community-level plant species richness
in the Western Siberian Arctic using macroecological models trained with
an extensive geobotanical dataset. We included vascular plants, mosses
and lichens in our analysis, as non-vascular plants substantially
contribute to species richness in the Arctic. Results We found that the
mean community-level plant species richness in this vast Arctic region
does not decrease with increasing latitude. Instead, we identified an
increase in species richness from South-West to North-East, which can be
explained by environmental factors. We found that paleoclimatic factors
exhibit higher explained deviance compared to contemporary climate,
potentially indicating a lasting impact of ancient climate on tundra
species richness. We also show that the existing protected areas cover
only a small fraction of the regions with highest species richness.
Conclusions Our results reveal complex spatial patterns of
community-level species richness in the Western Siberian Arctic. We show
that climatic factors such as temperature (including paleotemperature)
and precipitation are the main drivers of plant species richness in this
area, and the role of relief is secondary. We suggest that while plant
species richness is mostly driven by environmental factors, an improved
spatial sampling is needed to robustly assess anthropogenic impact on
species richness. Our approach can be used to design conservation
strategies and to investigate drivers of plant species richness in other
arctic regions.

Bismuth-based materials have been recognized as the appealing anodes for
potassium-ion batteries (PIBs) due to their high theoretical capacity.
However, the kinetics sluggishness and capacity decline induced by the
structure distortion predominately retard their further development.
Here, a heterostructure of polyaniline intercalated Bi2O2CO3/MXene
(BOC-PA/MXene) hybrids has been reported via simple self assembly
strategy. The ingenious design of heterointerface-rich architecture
motivates significantly the interior self-built-in electric field (IEF)
and high-density electron flow, thus accelerating the charge transfer
and boosting ion diffusion. As a result, the hybrids realize a high
reversible specific capacity, satisfying rate capability as well as
long-term cycling stability. The in/ex-situ characterizations further
elucidate the stepwise intercalation-conversion-alloying reaction
mechanism of BOC-PA/MXene. More encouragingly, the full cell
investigation further highlight its competitive merits for practical
application in further PIBs. Our present work not only opens the way to
the design of other electrodes with an appropriate working mechanism but
also offers inspiration for built-in electric-field engineering toward
high-performance energy storage devices.

Aqueous rechargeable zinc-ion batteries (ZIBs) have garnered
considerable attention due to their safety, cost-effectiveness, and
eco-friendliness. There is a growing interest in finding suitable
cathode materials for ZIBs. Layered vanadium oxide has emerged as a
promising option due to its ability to store zinc ions with high
capacity. However, the advancement of high-performance ZIBs encounters
obstacles such as sluggish diffusion of zinc ions resulting from the
high energy barrier between V2O5 layers, degradation of electrode
structure over time and consequently lower capacity than the theoretical
value. In this study, we investigated the pre-doping of different
cations (including , , and ) into V2O5 to enhance the overall charge
storage performance. Our findings indicate that the presence of V4+
enhances the charge storage performance, while the introduction of into
V2O5 (NH4-V2O5) not only increases the interlayer distance (d(001) =
15.99 Å), but also significantly increases the V4+/V5+ redox couple
(atomic concentration ratio increased from 0.14 to 1.08), resulting in
the highest electrochemical performance. The NH4-V2O5 cathode exhibited
a high specific capacity (310.8 mAh g-1 at 100 mA g-1), improved cycling
stability, and a significantly reduced charge transfer resistance
compared to pristine V2O5.
Developing Diluted Low Concentration Electrolyte with High Anion to Solvent Ratio for High-Voltage Lithium Metal Batteries

Published: November 2023

Low concentration electrolyte demonstrates significant advantages in
terms of cost, viscosity, and wettability. However, its high solvent
ratio usually induces fragile organic-rich solid electrolyte interphase
(SEI), which is not compatible with high-voltage lithium metal batteries
(LMBs). Herein, a screening rule for diluent has been established based
on the electrostatic potential, which guides the rational design of
diluted low concentration electrolyte (DLCE) with high anion to solvent
ratio. Specifically, the anti-solvating power of a diluent is positively
correlated with its value of the most positive surface potential
(ESPmax), thus diluents with high ESPmax value easily cause
salt-precipitation when diluting concentrated electrolyte to low
concentration (< 1 M). In light of this observation, diluent
with low ESPmax value is selected to ensure the preparation of a
transparent DLCE, thus maintaining high anion to solvent ratio in DLCE.
As an exemplary study, a 0.5 M ether-based DLCE is developed for
high-voltage LMBs. Due to the high anion to solvent ratio, a robust
LiF-rich SEI is formed and enables the stable operation of LMBs under
high-voltage (4.5 V) and wide temperature (−20 to 55 °C). This work
offers a guideline for screening diluent to design high-performance LCEs
for high-voltage batteries.
