Psychologia teorii spiskowych
Authors: Van Prooijenis Jan-Willem , Piszczek Katarzyna
Published: December 2023

Kto wierzy w teorie spiskowe i dlaczego niektórzy ludzie są bardziej podatni na wiarę w nie niż inni? Jakie są konsekwencje tego typu przekonań? Czy jakakolwiek teoria spiskowa okazała się kiedykolwiek być prawdą?
Psychologia teorii spiskowych obala mit, jakoby teorie spiskowe były zjawiskiem nowoczesnym poprzez zbadanie szerokiego kontekstu społecznego, w jakim powstają – od polityki po miejsce pracy. W książce tej autor wyjaśnia dlaczego niektórzy ludzie są bardziej podatni na wiarę w teorie spiskowe niż inni oraz jakie procesy psychologiczne, które możemy rozpoznać i przewidzieć leżą u podstaw powstawania tego typu przekonań.
Poprzez przytoczenie przykładów takich jak zamachy terrorystyczne z 11 września i zmiana klimatu, Psychologia Teorii Spiskowych pokazuje, że, podczas gdy tego typu przekonania nie zawsze są nieuzasadnione i posiadanie ich nie jest cechą patologiczną, mogą również wyrządzać wiele szkód zarówno jednostkom jak i społeczeństwu.

Published: December 2023

Background: The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources that would otherwise not be utilized by a single crop. The continuous application of inorganic fertilizers even in balanced form may not sustain soil fertility and productivity. However judicious use of chemical fertilizers in combination with organic manure is required to improve the soil health as well as to achieve sustainable crop production. Thus balanced fertilization and cropping system offers a great scope for increasing the productivity. Methods: A field experiment was conducted during kharif season of 2019 and 2020 in the experimental farm, Department of Agronomy, Nagaland University, SAS, Medziphema campus to study the effect of cropping system and nutrient management practices on production potential of rice-based cropping system. The experiment was conducted in randomized block design with factorial concept with 3 replications. The treatment consisted of five cropping systems and three nutrient management practices. Result: The result revealed that among intercropping system, rice + soybean (3:1) cropping system recorded highest plant height (cm), number of leaves plant-1, number of panicles m-2, grain yield, straw yield and rice equivalent yield. Among different nutrient management practices, application of 75% RDF + FYM @ 5 t ha-1 + biofertilizer consortium @ 20 g kg-1 seed recorded significantly higher plant height (cm), number of leaves plant-1, number of panicles m-2, panicle length, grain yield and straw yield.

Published: December 2023

A comprehensive mineralogical study of 13 samples of spheroidal gold from schlich concentrates of the Middle Kyvvozh gold placer, which is part of the Kyvvozh gold placer field located in the central part of the Volsk-Vym ridge of the Middle Timan, was carried out. The presence of both natural and technogenic gold in concentrates was established. Natural placer spheroidal gold is characterized by a worn surface with oxide films and the development of a high-grade corrosion rim. Technogenic gold spheroids have a polygonal-mosaic tuberculate-pitted or smooth surface, the presence of aluminosilicate glasses and slags in the form of crusts or inclusions in the matrix, the presence of mineral inclusions and impurities of platinum group metals, tin and lead, which are not characteristic of native gold. Natural spheroids were formed by natural smoothing in the water flow during the formation of the placer. The formation of technogenic spheroids is associated with the impact of high-temperature plasma on the concentrate enriched in placer gold and platinoids, which occurs during electric welding undertaken during the repair work of the flushing devices. The results of the study should help to avoid errors in the interpretation of the genesis of such gold and, as a result, in determining the nature of the primary sources of placers.

As a province rich in natural resources, especially mining products, South Kalimantan (South Kalimantan) is also not free from problems in the environmental sector. The massive mining activity in the province of South Kalimantan has caused environmental damage and loss of land cover in South Kalimantan. This happened because 41 percent of the Meratus forest and other forests in South Kalimantan were already burdened with mining permits. Efforts to balance the use of natural resources and the environment are through spatial planning based on the achievement of environmental function sustainability. The purpose of this study is to analyze the suitability of the RTRW, analyze the factors that influence the suitability of the RTRW, and analyze how big the positive and negative impacts of the suitability of the RTRW are. This research was conducted by making a land use map that aims to see how the situation is in the field and compare it with a planning map using a Geographic Information System. The results of the comparison of the planning map and the conditions in the field show the suitability of land use. The results obtained using Tapin's RTRWK in IUP MINERBA are 15.22%, which means that the implementation of space utilization is not appropriate. The influencing factors are the development of settlements which are increasing every year very rapidly due to the increasing population. The positive impact is that the companies have helped to repair village roads that are used by the community to reduce the number of unemployed, increase regional income levels, and improve the economic welfare of the surrounding community. The negative impact is environmental damage and social conflict in the community, increasing the vulnerability to traffic accidents due to increased road users.

Waste management in Palangka Raya City is in the Km Landfill. 14. The landfill is divided into 2 activities, namely waste management and leachate management installation. The waste management system is a method applied at the end point of waste processing. Waste collected at the landfill arrives at the landfill. The purpose of this study is to analyze waste generation, waste composition, and waste sources, analyze whether the waste management method affects the quality of leachate water and groundwater of the surrounding residents, and analyze the pollution index in the groundwater of the surrounding residents. This study uses a quantitative descriptive method by analyzing leachate and groundwater samples examined at the regional health laboratory. The results of these samples will be compared with leachate water quality standards, groundwater quality standards for sanitary hygiene purposes, and groundwater pollution index tests. The quality of leachate is unaffected by the operational method of waste processing. All leachate water samples for the parameters TSS and Cadmium are below the quality standard for final waste processing, except for the TSS value at station St2, this is because the wastewater is still in the waste pile area and has not yet entered the leachate management installation pond. The results of groundwater sample tests in several residents' homes for the pH parameter are below the quality standard. The pollution index results show that the water used daily is categorized as lightly polluted.

Published: December 2023

Brain tumors are one of the most fatal disorders owing to the uncontrolled proliferation of abnormal cells inside the brain. Digital images are obtained using Magnetic Resonance Imaging (MRI), which is a medical instrument that can assist doctors and other medical personnel in assessing and diagnosing the presence and type of brain tumors. However, manual and subjective classification is time-consuming and error prone. Hence, an objective, automatic, and more reliable method is needed to classify MRI images of brain tumors. Artificial intelligence is considered appropriate to determine the type of brain tumor via MRI images to overcome the constraints of conventional testing methods. One method for performing automatic classification is the Convolutional Neural Network (CNN). This work demonstrates how the Inception Resnet v2 architecture in CNN is utilized to classify MRI brain tumors into four categories via transfer learning, namely glioma tumors, meningioma tumors, no tumors, and pituitary tumors. The accuracy value of the generated model reached 93.4% after running for 20 epochs. It infers that artificial intelligence is beneficial in identifying a brain tumor objectively to help doctors and radiologists in the medical field.
“Meu pobre corpo é feito corpo de Deus": uma antropologia teológica entre corporeidade e espiritualidade
Authors: Dumer Pablo Fernando , Kriese Duffeck Jéssica Lais
Published: December 2023

Este artigo discute a antropologia teológica através dos temas da corporeidade e espiritualidade e a sua relação. Problematiza, numa perspectiva feminista, a dicotomia e o dualismo que a antropologia teológica envolveu-se e as consequências destas para o lugar e sentido que o corpo, especialmente o corpo das mulheres, sofre em nossa cultura e sociedade. Resgata o caráter indivisível de corpo e espírito na teologia e a importância do corpo como uma categoria teológica. Assim, propõe a superação dos dualismos referentes ao corpo e espírito, subvertendo-os ao falar de uma espiritualidade do corpo e uma corporeidade do espírito.

Introduction: Sickle cell disease (SCD) is an inherited hemoglobinopathy that can evolve with time, in some individuals, as a debilitating chronic pain syndrome with emotional dysfunctions. Objective: To evaluate different types of religiosities: organizational (ORA), non-organizational (NORA), and intrinsic religiosity (IR), and their correlation with mental health in individuals with SCD. The variables analyzed were depression, anxiety, and catastrophic and suicidal thoughts. Method: This is a descriptive cross-sectional study, which is part of a crossover randomized clinical trial. We recruited adults among individuals with SCD from Bahia-Brazil. We used: Duke's religiosity index, Hospital Anxiety and Depression Scale (HADS), and Brazilian Portuguese Pain Catastrophizing Scale (BP-PCS) data. The Spearman correlation and Fisher exact test were used for statistics considering alpha 95%. Results: Of the 131 individuals approached for participation, 75 completed all questionnaires with genotype HbSS and HbSC. Of them, 49 (65,3%) were women, with an average age of 34.13 +10.02, 66 (88.0%) self-declared black, 63 (84.0%) declared to belong to a religious group, 67 (89.3%) with a high form of religious involvement. The mean of intense pain was 3.86 + 2.74; 40 (53.33%) had anxiety, 25 (33.33%) had depression, and 15 (20.0%) declared having suicidal thoughts. There was a negative correlation between depression and IR (r = -0.240, p = 0.038) and a correlation between average pain and NORA (r = 0.301, p = 0.009). An association between NORA and chronic pain was verified (p = 0.023), OR (p < 0.001), NORA (p = 0.042), and IR (p = 0.004) with evangelical SCD subjects. Conclusion: This study highlights the need for mental health care in patients with SCD due to the high rates of anxiety and depression, with the need to include religiosity since it is a frequent and important element in the lives of people with SCD.
O rock e a espiritualidade não religiosa na socialização dos/das roqueiros/as sem religião

Published: December 2023

Neste artigo apresentaremos um fragmento da nossa tese de doutorado, através da pesquisa de campo com os relatos dos entrevistados. Para isto, indagamos, se, e como o rock poderia gerar um tipo de espiritualidade não religiosa na socialização dos/as roqueiros/as sem religião nos círculos urbanos headbangers em Belo Horizonte. Nossa hipótese procurou identificar se havia algum tipo de espiritualidade não religiosa na sociabilidade e solidariedade desses/as roqueiros/as sem religião. A metodologia nesta parte da pesquisa ocorreu de forma mista com a pesquisa de campo e pesquisa bibliográfica, tendo como principal teórico o sociólogo francês Michel Maffesoli. Embora, para a maioria desses participantes da pesquisa ocorra essa espiritualidade não religiosa com a socialização e solidariedade, através do rock, heavy metal e de seus subgêneros. Ela não é unanime, devido à rejeição que esse grupo demonstra em relação aos círculos e instituições religiosas, bem como a qualquer manifestação religiosa ou espiritual.

Ko‎‎ncepti inovacijskih sustava i politika nastali u sklopu industrijskog društva danas su u svojevrsnoj krizi jer su se i na teorijskoj i na praktičnoj razini ‎pokazali nemoćnima pridonijeti rješenju suvremenih društveno-ekonomskih ‎izazova. Hrvatska osim toga bilježi i gospodarsko nazadovanje u odnosu na ‎nove članice Europske unije, što otvara pitanje daljnjeg smjera njezine inovacijske politike. Cilj je ovog istraživanja objasniti nove koncepte inovacijske ‎politike – transformacijske inovacijske politike (TIP) i inovacijske politike s ‎misijom (IPsM), usmjerene na tranziciju socio-tehničkih sustava i tehno-ekonomskih paradigmi, s osvrtom na njihovu ulogu u hrvatskom inovacijskom ‎sustavu i zastupljenost transformacijskih inicijativa u sklopu Nacionalnoga ‎plana oporavka i otpornosti (NPOO).

Low-sidelobe Imaging Method Utilizing Improved Spatially Variant Apodization for Forward-Looking Sonar
Authors: Yan Lu , Yang Juan , Xu Feng , Piao Shengchun
Published: December 2023

For two-dimensional forward-looking sonar imaging, high sidelobes significantly degrade the quality of sonar images. The cosine window function weighting method is often applied to suppress the sidelobe levels in the angular and range dimensions at the expense of the main lobe resolutions. Therefore, the improved spatially variant apodization imaging method for forward-looking sonar is proposed to reduce the sidelobes without degrading the main lobe resolution in angular-range dimensions. The proposed method is a nonlinear post-processing operation in which the raw complex-valued sonar image produced by a conventional beamformer and matched filter is weighted by a spatially variant coefficient. To enhance the robustness of the spatially variant apodization approach, the array magnitude and phase errors are calibrated to prevent beam sidelobe heightening from occurring prior to beamforming operations. The analyzed results of numerical simulations and a lake experiment demonstrate that the proposed method can greatly reduce the sidelobes to approximately -40 dB, while the main lobe width remains unchanged. Moreover, this method has an extremely simple computational process.
Saturated Boiling Enhancement of Novec-7100 on Microgroove Surfaces with Anisotropic Properties

Published: December 2023

The effects of anisotropic properties (wettability and roughness) on microgroove surfaces in pool boiling heat transfer using Novec-7100 as a working fluid were experimentally investigated. The idea of introducing the concept of anisotropic wettability in boiling experiments draws inspiration from biphilic surfaces. The investigation is also motivated by two-phase immersion cooling, which involves phase-change heat transfer by using dielectric liquid as a working fluid. Very few studies have focused on the effects of surfaces with anisotropic properties on boiling performance. Thus, this study aims to examine the pool boiling heat transfer performance on surfaces with microgroove-induced anisotropic properties under the saturation condition. A femtosecond laser–texturing method was employed to create microgroove surfaces with different groove spacing. The results indicated that anisotropic properties affected the heat transfer coefficient and critical heat flux. Relative to the plain surface, microgroove surfaces enhanced the heat transfer performance due to the increased number of bubble nucleation sites and higher bubble detachment frequency. An analysis of bubble dynamics under different surface conditions was conducted with the assistance of high-speed images. The microgroove surface with groove spacing of 100 μm maximally increased the BHTC by 37% compared to the plain surface. Finally, the CHF results derived from experiments were compared with related empirical correlations. Good agreement was achieved between the results and the prediction correlation.
Gamification and new approaches in Engineering Education
Authors: Triantafyllou Serafeim
Published: December 2023

Engineering Education needs to be approached in different, innovative ways to meet the needs of society, learners, and education providers. This ranges from new educational programs and innovative pedagogies in individual classrooms, to online and immersive learning, to micro-credentials and modularity along with how to enable rapid adaptation for reskilling and upskilling, to entirely new pathways of restructuring education. Gamification is the application of game elements and digital game design techniques to non-game problems, such as learning challenges. It is about using game-based mechanics, aesthetics, and game thinking to enhance users’ engagement, motivate action, and support learning. At first view, the concept of gamification does not contain game design elements, but with the addition of additional elements such as the video game component that is applied in different contexts, the users are encouraged to participate in learning activities and complete learning challenges successfully. The first step in the process of designing a gamification activity is to think like a game designer. According to Cook (2013), any process can be gamified when the following requirements are covered: (i) the gamified activity is easy to learn, (ii) user progress can be measured, (iii) continuous feedback is provided to users.

Published: December 2023

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian level dedak aromatik yang berbeda terhadap kandungan asam laktat, pH, dan bahan kering silase rumput Pakchong. Dedak aromatik, dedak yang difermentasi menggunakan probiotik yang mengandung bakteri asam laktat, dicampurkan ke dalam silase rumput Pakchong sesuai dengan rancangan acak lengkap dengan empat taraf dedak aromatik sebagai perlakuan dan lima ulangan. Perlakuan level dedak aromatik yang ditambahkan yaitu P0 = Rumput Pakchong + 0% dedak aromatik, P1 = Rumput Pakchong + 1% dedak aromatik, P2 = Rumput Pakchong + 3% dedak aromatik, P3 = Rumput Pakchong + 5% dedak aromatik. Rumput Pakchong dan dedak aromatik dicampur secara homogen, dimasukkan ke dalam 20 unit silo toples kaca dengan kapasitas masing-masing 5 L, kemudian diinkubasi selama 21 hari. Pada akhir periode percobaan, dilakukan pengukuran nilai pH, kadar asam laktat, dan kadar bahan kering pada setiap satuan perlakuan. Hasil penelitian menunjukkan bahwa perlakuan dedak aromatik berpengaruh nyata (p<0,05) terhadap pH dan nilai asam laktat, namun tidak berpengaruh nyata terhadap nilai bahan kering. Silase rumput Pakchong yang mengandung level dedak aromatik yang lebih tinggi secara signifikan menurunkan nilai pH (dari 6,48 menjadi 5,95), namun pencapaian nilai pH ahkhir tersebut, belum memenuhi syarat sebagai silase berkualitas baik. Perubahan nilai pH juga diikuti dengan tren peningkatan kandungan asam laktat. Meskipun terdapat kecenderungan nilai bahan kering yang lebih tinggi pada silase yang mengandung dedak aromatik yang lebih tinggi, secara statistik perbedaan tersebut tidak signifikan. Disimpulkan bahwa level dedak aromatik yang ditambahkan hingga 5% pada penelitian ini tidak memperbaiki kualitas silase rumput Pakchong ditinjau dari nilai pH, asam laktat, dan bahan kering..

Published: December 2023

A new generation of pupils has grown up with a strong familiarity with technology in the context of Industry 4.0. This technological revolution has made learning a foreign language more critical. However, learning a foreign language can only be accessible with that crucial component- motivation. The purpose of this study was to find out how students' motivation to learn Mandarin was affected by gamification. A gamification application was designed with the Game Development Document (GDD) as a foundational guide, utilizing the Mechanics, Dynamics, and Aesthetics (MDA) architecture. Two schools participated in the experimental research project, with 56 and 58 students divided into control and experimental groups. A questionnaire gathered data, and SPSS was used to compute Cronbach's Alpha. The results showed that gamification increased students' enthusiasm to study Mandarin well. When employing gamification as a teaching strategy, students with different levels of Mandarin proficiency saw varied results. Therefore, gamification can tailor Mandarin language instruction to each student's needs and skill level.

The general health of palm trees, encompassing the roots, stems, and leaves, significantly impacts palm oil production, therefore, meticulous attention is needed to achieve optimal yield. One of the challenges encountered in sustaining productive crops is the prevalence of pests and diseases afflicting oil palm plants. These diseases can detrimentally influence growth and development, leading to decreased productivity. Oil palm productivity is closely related to the conditions of its leaves, which play a vital role in photosynthesis. This research employed a comprehensive dataset of 1,230 images, consisting of 410 showing leaves, another 410 depicting bagworm infestations, and an additional 410 displaying caterpillar infestations. Furthermore, the major objective was to formulate a deep learning model for the identification of diseases and pests affecting oil palm leaves, using image analysis techniques to facilitate pest management practices. To address the core problem under investigation, the GoogLeNet deep learning approach was applied, alongside various hyperparameters. The classification experiments were executed across 16 trials, each capped at a computational timeframe of 10 minutes, and the predominant duration spanned from 2 to 7 minutes. The results, particularly derived from the superior performance in Model 4 (M4), showed evaluation accuracy, precision, recall, and F1-score rates of 93.22%, 93.33%, 93.95%, and 93.15%, respectively. These were highly satisfactory, warranting their application in oil palm companies to enhance the management of pest and disease attacks.

O rio São Francisco tem apresentado, ao longo do tempo, diversos pontos de perda hídrica por toda sua extensão. No caso do seu trecho navegável presente no Norte de Minas Gerais, isso não é diferente, como é o caso específico de São Francisco, local de pesquisa deste estudo. Com o uso de ferramentas de geoprocessamento, foram analisadas imagens de satélite do leito do rio por todo o município ao longo de 41 anos (1975-2016), sendo possível apontar, após a sobreposição de imagens, os trechos onde houve perda da calha do rio e avanço do assoreamento, verificando-se, inclusive, a perda de 39,68% da área original do rio comparando-se 1975 e 2016; o aumento absoluto de 1.323% das áreas assoreadas e o crescimento absoluto de 207% das ilhas de sedimentação, além de dois pontos onde o rio simplesmente sedimentou. Como conclusões pode-se apontar o sucesso da metodologia aqui empregada, sendo indicado o uso destas mesmas ferramentas cartográficas em estudos futuros acerca de perda ou avanço de corpos hídricos.

Background: Mosquito-borne diseases are characterized by their specific biological transmission and these are able to imbibe the viruses on infected host. Tremendously affecting mosquito is Aedes and its species which are responsible as a vector for the diseases like malarial filariasis, dengue, chikungunya, Japanese encephalitis, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). With the upcoming health problems dengue virus is of great importance and is enzootic in humid and semitropical countries including Pakistan. Efforts have been made to fight with the proliferating disease to minimize the victims by controlling the population of Aedes. With the new era and the increase in epidemiology of the diseases the need of the hour is to incorporate some of the best and viable methods that result in bringing their number to the lowest and ultimately eliminating the Aedes population.
Results: The present study was carried out to check the capacity of Greenlid Bio-traps (GLBT) to minimize the overall population of Aedes in dengue risk areas under field trials. GLBT are internally coated with permethrin which is used to inhibit adult formation and is able to kill the adult female within 5 minutes after it came into contact with it. GLBT were placed in four different locations. Adults emerging from each of the GLBT were monitored and was compared with adults emerging from controlled conditions. The duration for the completion of the study was about 4-5 months. Data was collected on weekly basis. Late 3rd and 4th instar larvae of Cx. quinquefasciatus and Ae. aegypti were used as test insects. Pupa collection was done weekly to see adult emergence. Results of the study showed non-significant results and showed that the biotraps were effective in the open areas of school as compared to the houses where the traps were placed. Mosquito population was also found with the number of larvae, pupa and adults. These bio-traps are effective to a little extent against different mature and immature stages of mosquito species.
Conclusion: All of the traps mostly degraded or damaged from the bottom, not fully degraded. Most of the traps degraded at higher temperature of 45 C. Results for adult mortality, adult emergence, larval formation, larval mortality, pupal formation and deformation was non-significant. 2 trials were done in a time period of about 4 months. Somehow significant results were obtained and shows the non-significant difference in the study. There also the presence of adults, larvae and pupal formation in the UC: 3 where the traps were placed in an open environment in the schools to large extent because of the presence of the suitable temperature and the favourable breeding spots present there. It is concluded that the traps were less effective in the houses as compared with the schools areas where there present the mosquitoes population.

3.1. Background
Unequal and inequitable access to Covid-19 vaccines in low- and middle-income countries (L&MICs) was a major political, ethical and public health failure in the pandemic. However, vaccine developers’ practices were not monolithic, but rather, took diverse approaches to supplying different countries, with important implications for global access.
3.2. Results
Using data on R&D investments, regulatory approvals, manufacturing and purchase agreements, and vaccine deliveries, we identified six distinct business models that apply across the 14 COVID-19 vaccines with more international presence from 2020–2022. “Western Early Arrivers” Pfizer/BioNTech and Moderna supplied the largest volumes quickly and prioritized high-income countries (HICs) from registration to vaccine delivery. “Western Latecomers” Janssen and Novavax supplied intermediate volumes later, also prioritizing HICs but with a greater proportion to L&MICs. “Major Chinese Developers” Sinopharm and Sinovac supplied intermediate volumes early, primarily to middle-income countries (MICs). “Russian Developer” Gamaleya completed development early but ultimately supplied small volumes, primarily to middle-income countries (MICs). “Cosmopolitan Developer” Oxford/AstraZeneca supplied large volumes early to HICs and MICs at the lowest prices. Finally, “Small MIC Developers” CanSino, Bharat Biotech, Medigen, Finlay Institute and the Center for Genetic Engineering and Biotechnology (CGEB), exported relatively small volumes to a few MICs. Low-income countries (LICs) were not targeted by any developer, and received far fewer doses, later, than any other income group. Almost all developers received public funding and other forms of support, but we found little evidence that such support was leveraged to expand global access.
3.3. Conclusions
Each of the six business models has different implications for which countries get access to which vaccines, how quickly, and at which prices. Each offers different strengths and weaknesses for achieving equitable access. Our findings also suggest that Western firms had the greatest capacity to develop and deliver vaccines quickly during the pandemic, but such capacity is rapidly becoming more globally distributed with MICs playing a significant role, especially in supplying other MICs. Given the critical role of public support in enabling pandemic vaccine development and supply, governments have both the capacity and responsibility to craft international rules that will make responses to future pandemics more equitable and effective.

Despite advances in single-cell technologies and temporal sampling, the seamless connection of cell states over time and the inference of gene-gene relationships driving cancer cell state remains a formidable challenge. We present Cflows, a framework that combines neural ordinary differential equation network designed to unravel continuous cellular dynamics from timelapsed scRNAseq data with causality analysis to learn gene regulatory networks underlying cell state changes. When applied to a novel scRNAseq data from breast cancer in vitro models, we trace cell states back to their origins, allowing us to refine a marker profile for cancer stem cells (CSCs), and compute rich and complex gene-gene networks that drive pathogenic trajectories forward. Our comprehensive temporal regulatory networks reveal the dynamic transitions along the epithelial-to-mesenchymal (EMT) and the mesenchymal-to-epithelial (MET) trajectories. Newly, we identify estrogen-related receptor alpha (ESRRA) as a critical mediator of CSC plasticity and MET cell fate decisions. We extend Cflows to an in vivo xenograft model, demonstrating its potential for elucidating trajectories governing primary tumor metastasis to the lung. In summary, Cflows is an innovative algorithm that uncovers temporal molecular programs within dynamic cell systems from static single-cell data and has helped identify key drivers and transcriptional networks underlying cancer plasticity.
