Microwave and irreversible electroporation. The most applied techniques in the ablation of liver metastases.
Authors: Rodríguez Sanz MB
Published: February 2024

Cada año aumenta el número de casos de cáncer en España. Del total, más de 3.000 nuevos diagnosticados se corresponden con cáncer de hígado. Más del 50% de estos pacientes son candidatos a un tratamiento con técnicas mínimamente invasivas de ablación tumoral, metodología que, según los últimos estudios, mejora las tasas de recurrencia de la enfermedad, así como las expectativas y la calidad de vida de los pacientes.

La ablación tumoral es un tratamiento mínimamente invasivo, guiado por imágenes, que utiliza el calor o el frío extremo para destruir células tumorales cancerosas. Las técnicas de ablación tumoral guiadas por la imagen agrupan al conjunto de procedimientos en el que el "estímulo terapéutico" es administrado selectivamente en el área tumoral conservando indemne el resto del parénquima no tumoral. Están descritas siete técnicas de ablación, sin embargo, las más utilizadas en la actualidad es la ablación con microondas y la electroporación irreversible, por tal motivo, el objetivo del artículo es la revisión y actualización de estas dos técnicas.

On the Shaping of Nature by Capitalism and its Consequences–James O’Connor’s examination of the class politics of Monterey Bay
Authors: Xie Chuxiang
Published: February 2024

Three approaches to examining the ecological history and cultural landscape of Monterey Bay in Nature’s Reason –A Study in Ecological Marxism by James O’Connor break down the defense of the dualism of geopolitics and identity politics; reveal the anomalies in Monterey Bay’s regional history and political thought; uncover the nature and capital logic; talks about the shaping of nature by capitalism and its consequences; and calls for a deep reform of the mode of knowledge production that looks not only to the past but also to the future and reconstructs the politics of class. At the same time, we are warned against the infiltration of capitalist logic into nature and the dangers of “depoliticization”.

Published: February 2024

Kişilerin bir olay karşısında nasıl davranacaklarını tahmin edebilmek için onların eğilimlerinin, başka bir ifadeyle tutumlarının ölçülmesi gerekir. Tutumlar ise doğrudan değil ancak dolaylı yoldan ölçülebilmektedir. Bilimsel araştırmalarda bu amaçla en sık kullanılan tutum ölçekleri Thurstone, Likert, Guttman ve Osgood ölçekleridir. Bu kitapta bu dört ölçeğin her birinin geliştirilme aşamaları açık ve anlaşılır bir şekilde izah edilmeye çalışılmış, ölçeklerin sahip olması gereken güvenirlik ve geçerlik türlerine yönelik hazırlanmış olan örneklerin çözümlerine aynı açıklık ve sadelikle yer verilmesine özen gösterilmiştir. Likert ve Osgood ölçeklerine yönelik hazırlanan örneklerin çözümünde SPSS ve AMOS paket programları, Guttman ölçeğinin güvenirlik analizlerinde ise Excel programı kullanılarak işlem aşamaları elden geldiği kadar açık bir şekilde izah edilmeye çalışılmıştır.

Published: February 2024

El edema agudo de pulmón obstétrico (EAPO) es una complicación sumamente rara que puede ocurrir durante el período prenatal, parto y postparto, causando una importante tasa morbilidad y mortalidad en pacientes gestantes. La alteración de la fisiología normal se debe a la acumulación de líquido en el espacio intersticial y alveolar. Durante el embarazo y posparto se presenta con una prevalencia muy baja que llega a menos del 1% de casos. Particularmente la clínica se caracteriza por dificultad respiratoria que varía en intensidad y gravedad en dependencia al proceso fisiopatológico. Los factores de riesgo pueden encontrarse preexistentes en cada paciente, durante el embarazo o iatrogenias farmacológicas. La asociación más común que encontramos es con el desarrollo de preeclampsia debido al daño endotelial que se produce y permite la fuga de líquidos a nivel pulmonar. El tratamiento y control de la preeclampsia sería uno de los principales pilares en la prevención al desarrollo. De igual manera es importante las medidas tanto farmacológicas como no farmacológicas están dirigidas a disminuir la cantidad de líquidos y las medidas suplementarias para disminuir la morbilidad.

Analysis of Calophyllum Inophyllum Biodiesel Combustion with Variations of Magnetic Field Strength
Authors: Nasrul Ilminnafik  , Imam Rudi Sugara
Published: February 2024

The problems facing the world today are limited fossil fuels and increasing global warming due to fuel emissions. Therefore, there is a need to transition from fossil energy to alternative energy that is environmentally friendly and renewable. Biodiesel is an alternative material that can be used as a substitute for diesel fuel. This research aims to improve the combustion quality of calophyllum inophyllum biodiesel using the magnetic field influence method. The combustion test method uses a Bunsen burner and variations in magnetic strength of 4000 gauss, 8000 gauss and 12000 gauss are given. The equivalent ratios used in combustion analysis are 0.6:1, 0.7:1, 0.8:1, 0.9:1, 1:1, 1:1.1, and 1:1.2. The fuel and air flowing in the Bunsen pipe are heated to a constant temperature of 250°C for the fuel evaporation process. Then the resulting flame was analyzed for its combustion characteristics with RGB color variables, laminar burning velocity, and flame height. The research results show that the stronger the magnetic field effect, the more optimal the combustion quality will be. This is indicated by the increasingly strong magnetic field effect exerted on the flame, causing the red color intensity to decrease, the laminar burning velocity to increase, and the flame height to decrease. This is because the magnetic field can influence the movement of O2 molecules and cause a change in the orientation of the hydrocarbon from para to ortho. As a result, diffusion combustion becomes minimal and the combustion reaction becomes faster.

We present six strongly gravitationally lensed Lyα emitters (LAEs) at z ∼ 4–5 with Hubble Space Telescope (HST) narrowband imaging isolating Lyα. Through complex radiative transfer Lyα encodes information about the spatial distribution and kinematics of the neutral hydrogen upon which it scatters. We investigate the galaxy properties and Lyα morphologies of our sample. Many previous studies of high-redshift LAEs have been limited in Lyα spatial resolution. In this work we take advantage of high-resolution Lyα imaging boosted by lensing magnification, allowing us to probe subgalactic scales that are otherwise inaccessible at these redshifts. We use broadband imaging from HST (rest-frame UV) and Spitzer (rest-frame optical) in spectral energy distribution fitting, providing estimates of the stellar masses (∼108–109
M
⊙), stellar population ages (t
50 < 40 Myr), and amounts of dust (A

V
∼ 0.1–0.6, statistically consistent with zero). We employ nonparametric star formation histories to probe the young stellar populations which create the Lyα. We also examine the offsets between the Lyα and stellar continuum, finding small upper limits of offsets (<0.″1) consistent with studies of low-redshift LAEs, indicating our galaxies are not interacting or merging. Finally, we find a bimodality in our sample’s Lyα morphologies: clumpy and extended. We find a suggestive trend: our LAEs with clumpy Lyα are generally younger than the LAEs with extended Lyα, suggesting a possible correlation with age.

We report JWST/NIRSpec spectra of three distant T-type brown dwarfs identified in the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) survey of the Abell 2744 lensing field. One source was previously reported as a candidate T dwarf on the basis of NIRCam photometry, while two sources were initially identified as candidate active galactic nuclei. Low-resolution 1–5 μm spectra confirm the presence of molecular features consistent with T dwarf atmospheres, and comparison to spectral standards infers classifications of sdT1, T6, and T8–T9. The warmest source, UNCOVER-BD-1, shows evidence of subsolar metallicity, and atmosphere model fits indicate T
eff = 1300 K and [M/H] ∼ −1.0, making this one of the few spectroscopically confirmed T subdwarfs known. The coldest source, UNCOVER-BD-3, is near the T/Y dwarf boundary with T
eff = 550 K, and our analysis indicates the presence of PH3 in the 3–5 μm region, favored over CO2 and a possible indicator of subsolar metallicity. We estimate distances of 0.9–4.5 kpc from the Galactic midplane, making these the most distant brown dwarfs with spectroscopic confirmation. Population simulations indicate high probabilities of membership in the Galactic thick disk for two of these brown dwarfs, and potential halo membership for UNCOVER-BD-1. Our simulations indicate that there are approximately 5 T dwarfs and 1–2 L dwarfs in the Abell 2744 field down to F444W = 30 AB mag, roughly one-third of which are thick disk members. These results highlight the utility of deep JWST/NIRSpec spectroscopy for identifying and characterizing the oldest metal-poor brown dwarfs in the Milky Way.
Optimized Case Finding of tuberculosis among key populations in Ukraine. A follow up study
Authors: Liliia Masiuk , Geliukh Evgenia , Islam Zahedul , Davtyan Hayk
Published: February 2024

Introduction: In 2021, there were 4 million tuberculosis (TB) cases that were not detected by health systems, globally. Many of those cases are among hard-to-reach populations or key population groups. An Optimized Case Finding (OCF) strategy was introduced in Ukraine to enhance case detection and identify those “missing” cases. OCF included screening of up to eight referred household and social network contacts of an index TB case. Following the OCF project implementation, TB detection and characteristics of index cases and contacts were assessed.
Methodology: A cohort study using project data (July 2018 – April 2022) was conducted.
Results: In total 7,976 close contacts were engaged in the project from 1,028 index TB cases. Among the contacts, 507 were diagnosed with TB. The TB case detection was 6,356/100,000 and the number needed to investigate was 16. Multiple factors were identified as associated with TB detection including smoking, HIV, poverty, etc. About 90% of cases were identified at the initial screening of the contacts. OCF was proven to be 5.8 times more effective than the standard active case finding using household surveys and 106 times more effective than passive case finding in the general public.
Conclusions: Our study demonstrated the effectiveness of OCF in detecting cases among key population groups and their social networks. We encourage adaptation and use of OCF by civil society organizations that already work with key vulnerable populations around the globe.

Published: February 2024

Introduction: Coinfection of COVID-19 with influenza pathogens, may complicate the diagnosis, treatment, and prognosis, which is a new concern. This study aims to evaluate COVID-19 and influenza coinfected cases during the flu season, while the SARS-CoV-2 pandemic continues.
Methodology: The study was conducted between November 2021 and January 2022. A total of 1987 (1752 outpatients, 235 inpatients) patients were included, and 44 simultaneous COVID-19 and influenza laboratory-confirmed diagnoses.
Results: During the study period, 1553 patients were diagnosed with COVID-19, 390 influenza, and 44 were diagnosed with coinfection. The incidence of coinfected cases was 2.2% (n = 44) in all patients, When coinfected cases were examined, there was a statistically significant difference between the disease duration in the inpatients (19.86 ± 10.78 days) and the disease duration in the outpatients (7.63 ± 2.25 days) (p < 0.05). 31.8% (n = 14) of coinfected cases were hospitalized, and the mortality rate was 50.0% (n = 7) in hospitalized patients.
Conclusions: Coinfection with SARS-CoV-2 and İnfluenza was not uncommon. Data on coinfected cases are limited in the literature. The coinfection with SARS-CoV-2 and influenza A should be considered in patients with complaints such as fever, myalgia, weakness, shortness of breath, and cough during the flu season. Using the diagnostic test showing two diseases in a single sample may contribute to protecting patient and community health in follow-up and treatment.

Fungi play a vital role in ensuring a physiological balance in the surrounding environments, interacting closely with humans, plants, and animals. While most of the time their contribution is beneficial, occasionally, they can become harmful, especially in patients with weakened immune systems. The work at hand aims to present the most common fungal pathogens involved in invasive infections, focusing on fungi that are present in the tropical and temperate areas of the world. While in the former, due to the humid climate, most fungal infections are caused by dimorphic fungi such as Coccidioides spp., Blastomyces spp., Histoplasma spp., Emergomyces spp. and Paracoccidioides spp., in the latter, after Candida spp., the most frequent fungi that are involved in disseminated mycosis are Aspergillus spp., Fusarium spp. and species from the order Mucorales. Nowadays, the etiology, severity, and number of cases of fungal diseases are starting to rise significantly. There are no exact reasons reported for this increase, but several factors are thought to be incriminated: the expansion of the range of medical conditions that constitute risk factors for developing the disease, an improvement in the available diagnostic methods, the commodity offered by modern traveling services associated with the lack of an available vaccine against fungal infections, as well as climatic influences. All the above-mentioned aspects consequently caused infections that used to be endemic to be spread worldwide. Therefore, it is of critical importance to understand the epidemiology, clinical manifestations of fungi induced diseases, virulence factors, and diagnosis for each of those pathogens.

Introduction: To explore the association between vaccination status and the days of hospitalization in non-severe adult COVID-19 patients.
Methodology: We retrospectively analyzed the 368 non-severe adult COVID-19 patients which were divided into three groups according to their vaccination status. Univariate and multivariate linear regression analysis were performed to determine the correlation between vaccination and the days of hospitalization. A generalized additive model and hierarchical linear regression model were used for outcome analysis.
Results: In the regression equation, the increase in the number of vaccine shots was significantly correlated with the decrease in the days of hospitalization (all p < 0.001). Particularly, the reduction of the days of hospitalization in patients with 3 injections of the vaccine was more significant than that of the 0-1 injection group (β: -2.810, -2.525, and -2.831; p < 0.001). Curve fitting showed that the relationship between the number of vaccination injections and the days of hospitalization was approximately linear, and the β value was -1.522 (95% CI: -2.091 − -0.954; p < 0.001). Among various laboratory indexes, only the monocyte ratio significantly affected the correlation between the number of vaccination injections and the days of hospitalization, indicating an interaction (p =0.027). The β values of the monocyte ratio in normal and elevated groups were -2.230 (95% CI: -3.048 − -1.412; p < 0.001) and -0.763 (95% CI: -1.520 − -0.005; p = 0.050), respectively.
Conclusions: In non-severe adult COVID-19 patients, there was a negative linear correlation between the vaccination status and the days of hospitalization.

The spider family Sicariidae Keyserling, 1880 represented by the synanthropic Mediterranean recluse spider, Loxosceles rufescens (Dufour, 1820), is reported in the Philippines for the first time, based on morphological and molecular data. The introduced spider was observed in a small cave (Kamantigue Cave) in Lobo, Batangas Province. Considering the medical importance of this spider, the proximity of its habitat to human habitation and tourist sites poses a potential public health concern.

This study reports on the first record of the family Sicariidae in the Philippines and the fourth recorded occurrence of L. rufescens in Southeast Asia.

Aluminum alloys are frequently employed in the aeronautics industry due to the remarkable mechanical properties and lightweight nature of these materials. Moreover, thin film coatings are commonly applied in order to improve the corrosion resistance under harsh environments. In this work, Al 7075-T6 substrates were coated with nanostructured SiO2-TiO2 films using a sol-gel method. The experimental approach initially consisted in the preparation of a precursor agent using tetraethyl orthosilicate (TEOS) and triethoxy(octyl)silane (ETOS). Subsequently, nanoparticles of SiO2-TiO2 were mixed in order to develop thin films using a one-step dip coating method. The roughness, nanoindentation and corrosion properties were evaluated for the coated substrates. A finite element model was created for the nanoindentation test, which determined the mechanical response between the film-contact interface during loading conditions. The average hardness, elastic modulus and critical loads leading to fracture were verified. The nanoindentation test presented a significant increase in hardness for the coated Al 7075-T6 alloy, reaching a value of 4.6 GPa. The SiO2-TiO2 thin films presented uniform and compact surface coatings with high mechanical properties. Furthermore, the performed corrosion tests indicated moderate protection by the SiO2-TiO2 thin films. The SiO2-TiO2 thin films displayed a generalized corrosion throughout the surface, presenting oxides and fractured crystals in localized regions.

Integrating Green Renewable Energy Sources (GRES) as substitutes for fossil fuel-based energy sources is essential for reducing harmful emissions. The GRES are intermittent and their integration into the conventional IEEE 30 bus configuration increases the complexity and nonlinearity of the system. The Grey Wolf optimizer (GWO) has excellent exploration capability but needs exploitation capability to enhance its convergence speed. Adding particle swarm optimization (PSO) with excellent convergence capability to GWO leads to the development of a novel algorithm, namely a Grey Wolf particle swarm optimization (GWPSO) algorithm with excellent exploration and exploitation capabilities. This study utilizes the advantages of the GWPSO algorithm to solve the optimal power flow (OPF) problem for adaptive IEEE 30 bus systems, including thermal, solar photovoltaic (SP), wind turbine (WT), and small hydropower (SHP) sources. Weibull, Lognormal, and Gumbel probability density functions (PDFs) are employed to forecast the output power of WT, SP, and SHP power sources after evaluating 8000 Monte Carlo possibilities, respectively. The multi-objective green economic optimal solution consisted of 11 control variables to reduce the cost, power losses, and harmful emissions. The proposed method to address the OPF problem is validated using an adaptive IEEE bus system. The proposed GWPSO algorithm is evaluated by comparing it with PSO and GWO optimization algorithms in terms of achieving an optimal green economic solution for the adaptive IEEE 30 bus system. This evaluation is conducted within the confines of the same test system using identical system constraints and control variables. The integration of a small SHP with WT and SP sources, along with the proposed GWPSO algorithm, led to a yearly cost reduction ranging from $\$$19,368 to $\$$30,081. Simulation findings endorsed that the proposed GWPSO algorithm executes fruitfully compared to alternative algorithms regarding a consistent convergence curve and robustness, proving its potential as a viable choice for achieving cost-effective solutions in power systems incorporating GRES.
Local convergence study of tenth-order iterative method in Banach spaces with basin of attraction
Authors: Devi Kasmita , Maroju Prashanth
Published: February 2024

Many applications from computational mathematics can be identified for a system of non-linear equations in more generalized Banach spaces. Analytical methods do not exist for solving these type of equations, and so we solve these equations using iterative methods. We introduced a new numerical technique for finding the roots of non-linear equations in Banach space. The method is tenth-order and it is an extension of the fifth-order method which is developed by Arroyo et.al. [1]. We provided a convergence analysis to demonstrate that the method exhibits tenth-order convergence. Also, we discussed the local convergence properties of the suggested method which depends on the fundamental supposition that the first-order Fréchet derivative of the involved function $ \Upsilon $ satisfies the Lipschitz conditions. This new approach is not only an extension of prior research, but also establishes a theoretical concept of the radius of convergence. We validated the efficacy of our method through various numerical examples. Our method is comparable with the methods of Tao Y et al. [2]. We also compared it with higher-order iterative methods, and we observed that it either performs similarly or better for the numerical examples. We also gave the basin of attraction to demonstrate the behaviour in the complex plane.

Air-writing is a widely used technique for writing arbitrary characters or numbers in the air. In this study, a data collection technique was developed to collect hand motion data for Bengali air-writing, and a motion sensor-based data set was prepared. The feature set as then utilized to determine the most effective machine learning (ML) model among the existing well-known supervised machine learning models to classify Bengali characters from air-written data. Our results showed that medium Gaussian SVM had the highest accuracy (96.5%) in the classification of Bengali character from air writing data. In addition, the proposed system achieved over 81% accuracy in real-time classification. The comparison with other studies showed that the existing supervised ML models predicted the created data set more accurately than many other models that have been suggested for other languages.

The results of this work have a connection with the geometric function theory and they were obtained using methods based on subordination along with information on $ \mathfrak{q} $-calculus operators. We defined the $ \mathfrak{q} $-analogue of multiplier- Ruscheweyh operator of a certain family of linear operators $ I_{\mathfrak{q}, \mu }^{s}(\lambda, \ell) \mathfrak{f}(\varsigma) \; (s\in \mathbb{N}_{0} = \mathbb{N}\cup \{0\}, \mathbb{ N} = \left\{ 1, 2, 3, ..\right\}; \ell, \lambda, \mu \geq 0, 0 < \mathfrak{q} < 1) $. Our major goal was to build some analytic function subclasses using $ I_{ \mathfrak{q}, \mu }^{s}(\lambda, \ell)\mathfrak{f}(\varsigma) $ and to look into various inclusion relationships that have integral preservation features.
