Authors: Silva López Belén de Jesús , Morales Vázquez Eleazar
Published: February 2023

El aprendizaje del idioma inglés es una problemática que no solo afecta en niveles básicos y medio superior, sino también en estudiantes universitarios. Las causas que impiden un correcto proceso de aprendizaje de dicha lengua son multifactoriales, desde aspectos cognitivos, hasta sociales y afectivos. En este caso, son los factores afectivos los que se analizan en el presente trabajo. Así, se presentan los resultados de una investigación desarrollada con estudiantes de un nivel intermedio de inglés de la carrera Licenciado en Idiomas de la Universidad Juárez Autónoma de Tabasco. El enfoque implementado fue mixto y el estudio fue de tipo descriptivo. Para su realización, se llevó a cabo un cuestionario con preguntas cerradas y preguntas abiertas. Los resultados indicaron que la ansiedad, la desmotivación y un autoconcepto negativo afectan de manera significativa el aprendizaje del inglés de los estudiantes, lo que ocasiona un círculo de estancamiento en su adquisición de la lengua.

El experimento se llevó a cabo en la ciudad de Cusco usando una muestra de 220 personas entre 20 y 70 años divididas en tres rangos de edad: Joven, adulto y adulto mayor. Estimamos las tasas de descuento individuales para conocer las preferencias temporales respecto al ahorro voluntario pensional y saber si el nivel de impaciencia y falta de autocontrol eran una razón del bajo nivel de ahorro voluntario para la jubilación, también se incluyó la aversión al riesgo y la restricción de liquidez como variables de control. Nuestros resultados arrojaron tasas de descuento hiperbólicas en el grupo Joven y en el grupo adulto, aspecto por el que concluimos que el escaso ahorro voluntario para la jubilación se debe a que los grupos más productivos sobrevaloran su consumo presente y por eso no previenen su futuro; asimismo se encontró que las personas aversas al riesgo tienen más probabilidad de ahorrar para la jubilación y que la restricción de liquidez es un impedimento para suavizar el consumo.

College students are a special group who are going through a critical transition period from adolescence to adulthood and are trying to adjust, maintain good grades, plan for the future, and be away from home, so they are at risk of developing Mental Emotional Disorders (GME) such as depression, anxiety, and other psychiatric comorbidities. Based on this, college students who feel indications of mental problems should immediately talk to a psychologist. But in general, the difficulties faced by college students when conducting consultations, for example, the lack of mental health facilities in their environment or on their campus, shy to do the consultation, and the consultation fees. Based on these problems, an early detection process using an expert system is needed to assist college students in recognizing their mental health disorders. The Rule-Based Reasoning method focuses on expert rules that are entered into the system. Based on expert system testing using the Rule-Based Reasoning method on 10 experimental cases, almost all system results are in accordance with the detection made by the expert. Based on this, it is hoped that this system will help detect mental health disorders experienced by college students.

NEGOTIATING EXISTENCE IN A TECHNOLOGY PROFICIENT WORLD: UNDERSTANDING HUMAN VULNERABILITY IN REVOLT OF THE LAMEBREN BY MANJIRI PRABHU
Authors: Nair Neha , S Premalatha
Published: February 2023

Technology has proved its desirability long ago, but what is pestering the human mind is not its pervasiveness, but its communion. Humans are going through an age when technology is revaluating what it means to be human and are inadequately prepared for the new psychological world that is being created by them. In a tech-savvy world, machines primarily confer authority on people, eventually giving machines a sense of conjectured domination, which is purely inefficacious. Any technological advancement cannot only be viewed as “development” or “progression”, rather, as an evocative tool that immensely affect habits of human mind. These mere “tools” are of extensive emotional value to the users and are often even distension of themselves.
The present study focuses on how machines supersede human existence and are largely a threat to human mind and emotions. Man has created an extremely powerful object that acts as a deceptive companion, giving a space of recluse, yet never allows to be sanely alone. Manjiri Prabhu depicts a world where machines are invented with a motive to abuse and kill humans, considering them inferior to machines and of less significance. In a world where co-existence should be a norm for harmony, the present paper aims to analyze whether humans and machines can co-exist peacefully, and, whether the same can happen without obstructing the former’s essence and existence.
IMPACT OF FOOD INSECURITY AND QUALITY OF LIFE ON DECISION MAKING ABILITIES OF ADOLESCENT TRIBAL GIRLS
Authors: M. T Kaveri , R Praveen
Published: February 2023

There are different milestones to be achieved during the growth period for an individual. Adolescence is the second catch-up growth period due to rapid growth and development. Food insecurity is a major public health issue globally. There is a bi-directional relationship between food insecurity and quality of life and vice-versa. Adolescents are the most vulnerable group but are often neglected as the primary focus is on women and children. The determinants for thinness are - lower Socioeconomic Status (SES), lack of awareness of a balanced diet and access to nutritious food. The determinants of overweight are - lack of physical activity, higher SES and poor consumption of a healthy diet. Adolescent girls internalise problems leading to depression, anxiety and stress, while boys externalise problems by exhibiting changes in their attitude and behaviour. If these issues are left unattended, they can affect the quality of life of adolescents in the long run. The indigenous groups stay aloof from mainstream society and lose access to healthcare services leading to a triple burden of malnutrition like undernutrition, obesity and non-communicable diseases like hypertension, diabetes, cancer, etc. Adolescent tribal girls face issues like bonded labour, gender-based discrimination and harassment, which can affect their physical health and quality of life leading to poor decision-making abilities and affecting their adulthood.

Published: February 2023

Transformative learning is just aligning our self with co existential system. While we are struggling in this alignment we feel disharmony which finally resulted in discomfort and a sense of disrespect to self and others. Education is provided to sustain these alignments with the Co existential system. Life is not only to be alive but to live too. Education is to develop a sense of understanding about self and others. Education is to understand the relationship of one with self, family, society, state and then with nations. Understanding of the orders in systems of co existential reality is sole aim of all educational systems. Education must provide answers of questions such as why and how aspects of education. Education must prepare child to have skills of co existential living. Prepared to live happily and harmoniously with all around that exist is the golden objective of providing education. All schools curriculums and subjects must be visualized in true sense of co existential reality. This research article visualized the scope of curricular intervention in mathematics and English for ensuring the goal of quality education which could be able to produce human beings and not just machines. Mathematics itself is of the nature of patterns seeking, rational thinking, well organisation and independent thinking which capable children to take their own decisions for living happily. The concepts of number sense, understanding the concept of zero, abstractions of algebra and inceptions of geometrical shapes and ideas had infinite scope of providing life skills education through mathematics ideas. Whereas English being a common communicative language with four basic skills i.e. listening, speaking, reading and writing can be made more sensible, meaningful and supportive in imparting values to develop responsible and understanding human beings. The skills of decisions making with co existential understanding, living in harmony with physical and living entities can be developed with mathematical ideas and with supportive help of language (English) very naturally and effectively. The ultimate aim of living a worthy life can be achieved through these curricular interventions across all subjects of school and universities education. May the transformative power of education leads to a world of understanding and happiness!

Where Does the Energy Go during the Interstellar NH3 Formation on Water Ice? A Computational Study
Authors: Ferrero Stefano , Pantaleone Stefano , Ceccarelli Cecilia , Ugliengo Piero , Sodupe Mariona , Rimola Albert
Published: February 2023

In the coldest (10–20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions. Among their plausible roles, that of third body is advocated, in which the reaction energies of surface reactions dissipate throughout the grain, stabilizing the product. This energy dissipation process is poorly understood at the atomic scale, although it can have a high impact on astrochemistry. Here we study, by means of quantum mechanical simulations, the formation of NH3 via successive H-additions to atomic N on water ice surfaces, paying special attention to the third-body role. We first characterize the hydrogenation reactions and the possible competitive processes (i.e., H-abstractions), in which the H-additions are more favorable than the H-abstractions. Subsequently, we study the fate of the hydrogenation reaction energies by means of ab initio molecular dynamics simulations. Results show that around 58%–90% of the released energy is quickly absorbed by the ice surface, inducing a temporary increase of the ice temperature. Different energy dissipation mechanisms are distinguished. One mechanism, more general, is based on the coupling of the highly excited vibrational modes of the newly formed species and the libration modes of the icy water molecules. A second mechanism, exclusive during the NH3 formation, is based on the formation of a transient H3O+/NH2
− ion pair, which significantly accelerates the energy transfer to the surface. Finally, the astrophysical implications of our findings relative to the interstellar synthesis of NH3 and its chemical desorption into the gas are discussed.

We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, presently located half an arcsecond from the Galactic Center supermassive black hole. With both spectro-imaging observations of Br-γ line emission and Lp (3.8 μm) imaging data, we provide the first estimate of its orbital parameters and quantitative characterization of the evolution of its morphology and mass. We find that the leading edge of X7 appears to be on a mildly eccentric (e ∼ 0.3), relatively short-period (170 yr) orbit and is headed toward periapse passage, estimated to occur in ∼2036. Furthermore, our kinematic measurements rule out the earlier suggestion that X7 is associated with the stellar source S0-73 or with any other point source that has overlapped with X7 during our monitoring period. Over the course of our observations, X7 has (1) become more elongated, with a current length-to-width ratio of 9, (2) maintained a very consistent long-axis orientation (position angle of 50°), (3) inverted its radial velocity differential from tip to tail from −50 to +80 km s−1, and (4) sustained its total brightness (12.8 Lp magnitudes at the leading edge) and color temperature (425 K), which suggest a constant mass of ∼50 M
Earth. We present a simple model showing that these results are compatible with the expected effect of tidal forces exerted on it by the central black hole, and we propose that X7 is the gas and dust recently ejected from a grazing collision in a binary system.

We present timing solutions for 12 pulsars discovered in the Green Bank North Celestial Cap 350 MHz pulsar survey, including six millisecond pulsars (MSPs), a double neutron star (DNS) system, and a pulsar orbiting a massive white dwarf companion. Timing solutions presented here include 350 and 820 MHz Green Bank Telescope data from initial confirmation and follow-up, as well as a dedicated timing campaign spanning 1 ryr PSR J1122−3546 is an isolated MSP, PSRs J1221−0633 and J1317−0157 are MSPs in black widow systems and regularly exhibit eclipses, and PSRs J2022+2534 and J2039−3616 are MSPs that can be timed with high precision and have been included in pulsar timing array experiments seeking to detect low-frequency gravitational waves. PSRs J1221−0633 and J2039−3616 have Fermi Large Area Telescope gamma-ray counterparts and also exhibit significant gamma-ray pulsations. We measure proper motions for three of the MSPs in this sample and estimate their space velocities, which are typical compared to those of other MSPs. We have detected the advance of periastron for PSR J1018−1523 and therefore measure the total mass of the DNS system, m
tot = 2.3 ± 0.3 M
⊙. Long-term pulsar timing with data spanning more than 1 yr is critical for classifying recycled pulsars, carrying out detailed astrometry studies, and shedding light on the wealth of information in these systems post-discovery.
First data on testate amoebae associated with the endemic cave bivalve Congeria jalzici Morton & Bilandžija, 2013 with a description of Psammonobiotus dinarica sp. nov.

Testate amoebae are phylogenetically a very diverse group of eukaryotic microorganisms. They can be found in marine and freshwater habitats and in soil. Some of these single-celled organisms inhabit both surface and cave habitats, but their diversity in caves has barely been explored. Recent studies in the Dinaric region imply that testate amoebae in caves show a high diversity. The aim of this study was to identify the alpha diversity of testate amoebae in the Lika region (Dinaric karst, Croatia) and to compare the habitats of different caves based on testate amoebae assemblages. In eight caves we found more than 40 testate amoebae taxa, including a new testate amoeba species, Psammonobiotus dinaricasp. nov. The greatest diversity of testate amoebae was found in Markov ponor (27 taxa). The Bray-Curtis Similarity Index showed that testate amoebae assemblages in caves inhabited by the endemic and endangered cave bivalve Congeria jalzici (Markov ponor, Dankov ponor and Dražice ponor) differ from caves not inhabited by this species. This differentiation is attributed to the impact of the sinking Lika river, which occasionally completely submerges these caves, creating specific habitats for eukaryotic microorganisms. This study contributes to our understanding of the diversity, biogeography and ecology of testate amoebae in caves, as well as providing further insight into the conditions that sustain populations of C. jalzici.

Predicting factors and top gene identification for survival data of breast cancer
Authors: Ghosh Sarada , Samanta Guruprasad , De la Sen Manuel
Published: February 2023

For high-throughput research with biological data-sets generated sequentially or by transcriptional micro-arrays, proteomics or other means, analytic techniques that address their high dimensional aspects remain desirable. The computation part basically predicts the tendency towards mortality due to breast cancer (BC) by using several classification methods, i.e., Logistic Regression (LR), Random Forest (RF), Support Vector Machine (SVM), Linear Discriminant Analysis (LDA) and Decision Tree (DT), and compared the models' performances. We proceed with the RF method since it provides better results than any other underlying models based on accuracy. We have also demonstrated some traditional and competing risk models, illustrated the models with real data analysis, depicted their curves' natures and also compared their fits using prediction error curves and the concordance index. Furthermore, two different survival splitting rules are used by using separate Random Survival Forest (RSF) methods and also constructing the ranking of risk factors due to breast cancer. The results show that high-level grade and diameter are the most important predictors for mortality progression in the presence of competing events of death, and lymph nodes, age and angiography are other vital criteria for this purpose. We have also implemented RSF backward selection criteria, which enables top gene selection related to mortality progression due to breast cancer. This method identifies c-MYB, CDCA7, NUSAP1, BIRC5, ANGPTL4, JAG1, IL6ST, and remaining genes that are mainly responsible for mortality progression due to breast cancer. In this work, R software is used to obtain and evaluate the results.
Dynamic event-triggered adaptive finite-time consensus control for multi-agent systems with time-varying actuator faults
Authors: Zhang Na , Xia Jianwei , Liu Tianjiao , Yan Chengyuan , Wang Xiao
Published: February 2023

In this study, the adaptive finite-time leader-following consensus control for multi-agent systems (MASs) subjected to unknown time-varying actuator faults is reported based on dynamic event-triggering mechanism (DETM). Neural networks (NNs) are used to approximate unknown nonlinear functions. Command filter and compensating signal mechanism are introduced to alleviate the computational burden. Unlike the existing methods, by combining adaptive backstepping method with DETM, a novel finite time control strategy is presented, which can compensate the actuator efficiency successfully, reduce the update frequency of the controller and save resources. At the same time, under the proposed strategy, it is guaranteed that all followers can track the trajectory of the leader in the sense that consensus errors converge to a neighborhood of the origin in finite time, and all signals in the closed-loop system are bounded. Finally, the availability of the designed strategy is validated by two simulation results.
mfeeU-Net: A multi-scale feature extraction and enhancement U-Net for automatic liver segmentation from CT Images
Authors: Liu Jun , Yan Zhenhua , Zhou Chaochao , Shao Liren , Han Yuanyuan , Song Yusheng
Published: February 2023

Medical image segmentation of the liver is an important prerequisite for clinical diagnosis and evaluation of liver cancer. For automatic liver segmentation from Computed Tomography (CT) images, we proposed a Multi-scale Feature Extraction and Enhancement U-Net (mfeeU-Net), incorporating Res2Net blocks, Squeeze-and-Excitation (SE) blocks, and Edge Attention (EA) blocks. The Res2Net blocks which are conducive to extracting multi-scale features of the liver were used as the backbone of the encoder, while the SE blocks were also added to the encoder to enhance channel information. The EA blocks were introduced to skip connections between the encoder and the decoder, to facilitate the detection of blurred liver edges where the intensities of nearby organs are close to the liver. The proposed mfeeU-Net was trained and evaluated using a publicly available CT dataset of LiTS2017. The average dice similarity coefficient, intersection-over-union ratio, and sensitivity of the mfeeU-Net for liver segmentation were 95.32%, 91.67%, and 95.53%, respectively, and all these metrics were better than those of U-Net, Res-U-Net, and Attention U-Net. The experimental results demonstrate that the mfeeU-Net can compete with and even outperform recently proposed convolutional neural networks and effectively overcome challenges, such as discontinuous liver regions and fuzzy liver boundaries.

Published: February 2023

Understanding human personality is essential for natural and social engagement. Arises a significant connection between users' personalities and their behavior. Our primary goal is to identify and classify individuals' personality traits based on their behaviors. Understanding personality types can help better understand preferences and potential differences between them. This study uses users' answers based on the questionnaire on personality to automatically identify the personality type based on behaviors. After pre-processing the data, we researched many classification techniques for automated recognition, including Naive Bayes, Support Vector Machine (SVM), Multilayer Perception (MLP), Random Forest, Logistic, and Decision Tree using a 10-fold cross-validation method. The second observational study combined all the algorithms using an Ensemble Learning algorithm, where by Vote algorithm. Accuracy, precision, recall, f-measure, and error values have been used to measure the systems' performance. According to the comparison analysis, SVM outperforms (85.8%) the other five personality trait detection algorithms. But after combing the five algorithms which contain the highest accuracy by Ensemble Learning algorithm obtained the highest performance (90.5%) than the SVM algorithm and obtained the highest recall, f-measure, and precision values, and the lowest error rates. It demonstrates that an ensemble learning approach that incorporates multiple distinct algorithms may yield greater accuracy than any one of its individual algorithms separately. Our findings are helpful for understanding how to manage and make a relationship with humans by predicting their personality earlier.

Published: February 2023

Idiopathic pulmonary fibrosis (IPF) is a chronic disease with an unknown etiology that causes deterioration of the structure of the lung parenchyma, resulting in a severe and progressive decline in respiratory function and early mortality. IPF is essentially an incurable disease, with a mean overall survival of 5 years in approximately 20% of patients without treatment. The combination of a poor prognosis, uncertainty about the disease's progression, and the severity of symptoms has a significant impact on the quality of life of patients and their families. New antifibrotic drugs have been shown to slow disease progression, but their impact on health-related quality of life (HRQoL) has to be proven yet. To date, studies have shown that palliative care can improve symptom management, HRQoL, and end-of-life care (EoL) in patients with IPF, reducing critical events, hospitalization, and health costs. As a result, it is essential for proper health planning and patient management to establish palliative care early and in conjunction with other therapies, beginning with the initial diagnosis of the disease.
A Case Series of Synostosis/Blocks Observed in Indian Human Vertebra

Not just anatomists but also clinicians from a variety of disciplines, including orthopedic doctors, surgeons, neurologists, and neurosurgeons, are interested in vertebral abnormalities. Numerous morphological anomalies, such as spinal synostosis, occipitalization, sacralization, and lumbarization, as well as the absence of the posterior vertebral arch, have been reported. Sequentially fused vertebral segments might result in spinal fusion, synostosis of the vertebrae, or blocked vertebrae. Movement limitations, early degenerative changes, and accompanying neurological abnormalities may all be brought on by the block vertebrae. The fusion may be whole or partial, acquired, or congenital. The cervical, lumbar, and thoracic vertebral levels are the most frequently affected by vertebral fusion, whether it is congenital or acquired. A systemic disorder, known as idiopathic diffuse idiopathic skeletal hyperostosis (DISH), is defined by distinctive ossification patterns that can run over at least three more vertebral levels or four successive vertebrae on their anterolateral aspect. Here, we present a series of spinal synostosis at various levels that were identified in museum specimens from our institution and that were associated with the clinical and developmental importance.

Complications in deep anterior lamellar keratoplasty – A retrospective cross sectional interventional analysis in a large series
Authors: Kodavoor Shreesha Kumar , Rathi Neha , Dandapani Ramamurthy
Published: February 2023

AIM:

To analyse complications in patients managed with deep anterior lamellar keratoplasty (DALK) for diseases of anterior corneal stroma.

MATERIALS AND METHODS:

This was a retrospective analysis of all the patients who underwent DALK in a tertiary care center in South India from 2010 to 2021. A total of 484 eyes in 378 patients were included in the study. Patients who underwent DALK for advanced keratoconus, keratoconus with Bowman's membrane scar, healed hydrops, macular corneal opacity, macular corneal dystrophy, granular corneal dystrophy, spheroidal degeneration, pellucid marginal degeneration, post-LASIK ectasia, descemetocele, postcollagen cross-linking aborted melt and dense scar, and postradial keratotomy were included in the study. The patients were followed up for 17.6±9.4 months(1–10years).

RESULTS:

Complications noted in the surgery were intraoperatively Descemet's membrane perforation in 32 eyes (6.6%), postoperatively secondary glaucoma in 16 eyes (3.31%), cataract in 7 eyes (1.45%), suture-related complications in 5 eyes (1.03%), graft rejection in 3 eyes (0.61%), traumatic dehiscence in 2 eyes (0.41%), filamentary keratitis in 2 eyes (0.41%), interface infiltrate in 1 eye (0.21%), and recurrence of disease in 4 eyes (8.77%) out of 57 eyes with corneal dystrophy.

CONCLUSION:

DALK as an alternative to penetrating keratoplasty for anterior corneal stromal diseases has proven to be better time and again. It has become an automatic choice for diseases of anterior cornea requiring keratoplasty. Complications occurring at any stage of surgery can be identified and managed effectively resulting in optimal outcome. This article compiles complications post DALK.
Bietti crystalline dystrophy complicated by choroidal neovascularization treated with a single dose of aflibercept
Authors: Ozbek Merve , Pehlivanoglu Seren , Artunay Halil Ozgur
Published: February 2023

Bietti crystalline dystrophy is a rare hereditary autosomal recessive disease that causes photoreceptor loss secondary to degeneration of retinal pigment epithelium due to intracellular retinal pigment epithelial crystalline deposits and abnormal lipid metabolism. We aimed to present a case of choroidal neovascular membrane secondary to Bietti crystalline dystrophy diagnosed with multimodal imaging and treated with an intravitreal injection of aflibercept. A single dose of aflibercept injection might be effective due to its higher affinity for vascular endothelial growth factor (VEGF) in comparison with other anti-VEGFs. It might be a treatment alternative that can be considered in the choroidal neovascular membrane due to uncommon etiologies.

$\ell _p$
among symmetric bases (Altshuler [1976, Israel Journal of Mathematics, 24, 39–44]), we obtain similar characterizations among democratic bases and among bidemocratic bases. We also prove a separate characterization of the unit vector basis of

Mauss, Marcel (1872–1950)
Authors: Guédon Cécile
Published: February 2023

Born in Épinal, France, Marcel Israël Mauss, the nephew and a disciple of Émile Durkheim, was a sociologist whose work greatly influenced the nascent discipline of anthropology. After teaching ‘History of Religion and Uncivilised Peoples’ at the École pratique des hautes études from 1901 to 1931, he took up the chair of Sociology at the Collège de France. He is widely known for his study of the rites of exchange across cultures (‘Essai sur the don’, 1923–1924). In Mauss’s theory, the gift is seen as the result of an almost magical operation that goes beyond the sheer materiality of the object presented, engaging the receiver as well as the giver in a form of spiritual transaction.
Popper, Karl (1902–1994)
Authors: Gardett M. Isabel
Published: February 2023

Karl Raimund Popper was one of the twentieth-century’s most influential philosophers of science. Qualified to teach elementary school and to teach physics and mathematics at the secondary level, Popper received his Ph.D. in Philosophy from the University of Vienna in 1928. Popper’s first and most influential work was The Logic of Scientific Discovery (Logic der Forschung), originally published in 1934 and translated into English by Popper in 1959. Popper was critical of positivism and of the inductive mode of science, in which observation of singular instances could lead to universal claims. Even large numbers of singular instances, he claimed, could never conclusively demonstrate a universal claim.

Kurt Pinthus—pen name Paulus Potter—was a German-Jewish publicist, editor, and critic, who is considered as one of the most important mediators of literary expressionism in Germany. He was born in Erfurt, studied literary history, philosophy, and history and obtained his doctoral degree in 1910. As a proofreader and literary advisor at the Kurt Wolff and Rowohlt publishing houses, he contributed to the publication of authors like Franz Kafka, Else Lasker-Schüler, Georg Heym, and Gottfried Benn. His anthology of expressionist poetry Menschheitsdämmerung (Dawn of Humanity, 1919/20) became an influential standard reference of literary expressionism. In 1933, Pinthus’ name appeared on the National Socialists’ list of banned literature. He fled to New York in 1937, eventually returning in 1967. Up until the 1970s, his articles addressed the life and work of writers persecuted by National Socialism.
