Percepción de amenaza como mediadora de la relación entre los estereotipos y el prejuicio hacia los migrantes venezolanos en Perú
Authors:   Pontificia Universidad Católica del Perú, Perú, Gomez Robinson Milagros , Espinosa Agustín ,   Pontificia Universidad Católica del Perú, Perú
Published: June 2021

Objectives: The present study aims to explore the relationship between stereotypes (morality, warmth, and competence) and prejudice (subtle and blatant) towards Venezuelan immigrants in Peru. In addition, the role of threat perception as a mediator in the relationship between stereotypes and prejudice towards this social group is analyzed. Method: A correlational research design was conducted, using the Subtle and Blatant Prejudice Scale, the National Stereotypes Scale, and the Out-Group Threat Perception Scale. The sample consisted of 115 participants of Peruvian nationality between 18 and 60 years old (M = 29.6; SD = 11.77). Results: The results confirm the inverse relationship between positive representation and ambivalent prejudice. In other words, when Venezuelans are represented as more competent, warm and moral, there are fewer expressions of subtle and blatant prejudice towards this social group. The regression coefficient of the relationships between stereotypes and prejudice tends to decrease when perceived threat is incorporated as a mediating variable in the partial mediation model. Conclusions: The relationships between the studied variables are confirmed. Furthermore, their importance for the implementation of interventions that promote intergroup contact, social inclusion, and questioning of social agents that reinforce a threatening representation of the Latin American immigrant is discussed.

The Relevance of Islam in Belgium and Future Perspectives
Authors: Riaño Sergio Castaño
Published: June 2021

Migration in Belgium in the 1960s represented the beginning of a social transformation process that has turned the traditionally Catholic country into a multicultural reality where Islam has achieved more significance. Consequently, the government had to adapt different structures to the new reality, and people had to learn to live together. In this regard, the Muslim community demanded public spaces to develop cultural and religious events. Second and third generations of Belgian Muslims conserve their family roots and require space for Islam in Belgium. As a result, progressively, the state has incorporated soft elements of Sharia Law in national and local legislation to respond to Muslim requirements. This fact has opened a debate in Belgium and has created controversies in some environments. Thus, this article analyses the implementation of Sharia Law legislation in Belgium and its consequences.

Authors: Tonsy Sara
Published: June 2021

The Muslim Brotherhood (MB) in Egypt has been known for being one of the most resilient Islamist organizations worldwide during most of the twentieth century, and until 2013. The Arab uprisings that swept over the Arab region resulted in the resurrection of the MB’s discourse changed drastically over the period of the organization’s existence and even further during the few years from 2011 until today. How did the discourse established by the MB develop and transform towards becoming a normalized version of Islam in Egypt? How could this be traced in the recent events the MB witnessed in Egypt, starting in 2011? Applying P. Bourdieu’s concept of symbolic power and O. Roy’s idea about post-Islamism this article will address these questions using field work and relevant literature.

Метою статті є дослідження причин і наслід- ків кризи у системі гігієни та охорони здоров’я у сучасному сус- пільстві і аналіз шляхів її подолання, які пропонуються авто- ритетними спеціалістами в галузі біології, медицини, охорони здоров’я. Методологічними засадами дослідження є загальна концепція самоорганізації і розвитку життя як складної бага- товимірної системи, методи й підходи титульних дисциплін постнекласичної науки, а саме синергетики, еволюційної гене- тики, еволюційної астрофізики, універсальної історії. Наукова новизна. Сучасна цивілізація прагне витіснити за межі ойку- мени всі живі організми, що загрожують життю людини або життю й гіпертрофованої продуктивності культивованих рослин і тварин. Знаряддям цієї боротьби є отрути, що знищу- ють мікроорганізми та диких представників флори і фауни, які конкурують із культурними. Одним із наслідків такої практики є різке зростання неінфекційних, автоімунних захворювань за останні півстоліття. Ріст несподіваний і непередбачуваний. Причиною сліпоти науки є сприйняття людини як певної суб- станціональної сутності, що знаходиться в зовнішніх відноси- нах з іншими представниками біосфери. Насправді це не так. Людське тіло є екологічною нішою, чимось на кшталт корало- вого рифу, де в складних відносинах симбіозу співіснують імунна, нервова, травна системи та мікробіом. Наслідком агресивної стратегії створення життєвого простору людини є знищення не тільки шкідливих мікроорганізмів, але й частини мікробіома, що веде до неадекватної реакції імунної системи на ті чи інші виклики. Висновки. Врахування складності людської присут- ності у світі та обмеження негативного впливу на мікробіом та інших живих істот є необхідною умовою поліпшення люд- ського життя і здоров’я та адекватних ситуацій, що склались, програм оптимізації способу життя, суспільного виробництва як «виробництва», відтворення людини перш за все.
ТРАНСЦЕНДЕНТИЗМ ЯК ЧИННИК ОТОТОЖНЕННЯ АКСІОЛОГІЧНОЇ ТА ЕТИЧНОЇ ПРОБЛЕМАТИКИ В ЗАХІДНОЄВРОПЕЙСЬКІЙ ФІЛОСОФІЇ
Authors: БУДЗ Андрій
Published: June 2021

Метою статті є обґрунтування трансцендентиз- му як чинника, який здійснив вплив на ототожнення аксіологічної та етичної проблематики в західноєвропейській філософії, починаючи від античної філософії та завершуючи початком ХХ ст. Методологічними засадами дослідження є парадиг- мальний підхід до специфіки розвитку історико-філософського процесу, який поєднується з генеалогічним методом, методами контекстуального аналізу, проблемно-категоріального аналізу й історико-філософської реконструкції. Наукова новизна. У статті розроблена концепція ототожнення аксіологічної та етичної проблематики в західноєвропейській філософії на основі парадигми трансцендентизму. Обґрунтовано, що транс- цендентизм у західноєвропейській філософії, який розвивається у філософських системах, починаючи з античності, створює підґрунтя для ототожнення низки аксіологічних та етичних понять, зокрема етичних – «цінність», «ідеал» та етичних – «благо», «щастя», унаслідок чого аксіологічна сфера включають- ся в етику та не виділяється як окрема наука. Висновки. Ото- тожнення аксіології та етики в західноєвропейській філософії, виходячи з аналізу основних ідей філософів, відбувається на семантичному рівні, який має світоглядні витоки. Зокре- ма, ототожнення аксіологічних (цінність, ідеал) та етич- них понять (благо, щастя) у західноєвропейській філософії ґрунтується на парадигмі трансцендентизму. Остання, у свою чергу, засновується на ідеї наявності вищої реальності, яка існує онтологічно, є справжньою, істинною та володіє найви- щими ступенями якостей речей, власне, сама є благом, цінністю й ідеалом. Унаслідок такого бачення буття людина не може самостійно будувати аксіологічні та гносеологічні системи, власне, не може бути «творцем» цінностей та істини, а здат- на тільки долучатися й розвивати вже наявні істини, ціннісні системи та ідеали, які мають трансцендентне походження.

Published: June 2021

The development of marketing strategies has long been engaged in by scientists and practitioners who have written countless algorithms, mechanisms and schemes for the successful development of a marketing strategy. However, in current conditions, all these developments have become obsolete for one main reason: the behaviour of the buyer has radically changed. This reason has again raised the need to develop effective recommendations for the formation of a marketing strategy for the enterprise's financial growth. The authors analyzed the main aspects of strategic planning, studied the features of the leading marketing strategies. The development of a marketing strategy for an enterprise follows almost the same scheme; however, the study showed that customers had changed dramatically: first of all, they are interested in the personal attitude, and only then in the quality of the goods, the price – the usual indicators that have always been in the first places. Taking into account the changed vector, the authors adapted the algorithm for developing a marketing strategy for the financial growth of an enterprise and tested the operation of one of the proposed tools on a real example, which showed its effectiveness in current conditions.

Published: June 2021

The training of professional teachers is dictated by the fundamental changes taking place in education. In the new social and pedagogical conditions, a professional teacher is required. Unlike a specialist teacher, a professional teacher, firstly, is a subject of the pedagogical activity, and not a bearer of a set of scientific knowledge and methods of its transmission; secondly, it is focused on the development of human abilities, and not only on the transmission of knowledge, abilities and skills; thirdly, he can practically work with educational processes, to build developing educational situations, and not just to pose and solve didactic problems. The analysis of literary sources allowed the authors to achieve the goal of the article: to develop theoretical and methodological tools for the significant formation of pedagogical thinking of future teachers, namely, to offer and test a model for the formation of pedagogical thinking of future teachers. The approbation showed an increase in all indicators that were assessed, as well as an increase in additional indicators: student attendance and their involvement in the educational process, which was manifested in an increase in the number of students who came to consultations, an increase in the number of requests from students to study additional literature on the topic, for additional research work, etc. Thus, the development of pedagogical thinking becomes both a process and a result of teaching a future teacher.

Published: June 2021

Today is characterised by the formation and development of an open, civilised society; there are fundamentally new forms of communication-based on the social and personal partnership, competition, legal and social foundations of formal equality of all citizens, the rational regulation of social relations. The quantity and quality of communications are continually growing, a significant number of people are involved in the communication process, the relationship between individual communications becomes close, the action of communications whose network has reached a global scale is growing. Modern communication society is characterised by a constant increase and globalisation of communications. The consequence of this development of society is the extremely limited financial resources, significantly narrowing the range of measures and tools to improve the management of the organisation as a whole and its staff, in particular, on the one hand, and changes in the emotional and mental spheres of the employee. Therefore, in their study, the authors considered the concept of communication, types of communication, their impact on the management process of the organisation and identified the role and functions of social communications in personnel management. The authors studied and analysed the methods of personnel management in detail. Based on the theoretical and methodological analysis, the authors proposed a system for managing the behaviour of staff through social communications; proposed a matrix for the distribution of responsibilities and this system and proposed a method for evaluating its effectiveness.

Published: June 2021

The study is devoted to the development of activities for the development of research activities of students in the learning process in universities. The authors analysed the essence of students' research activities, identified the main tasks of students' research activities and formed a hypothesis that the development of students' research activities in the process of studying at a university will be useful and will be reflected in the dynamics of their creative self-development if it is carried out within the framework of the research development program as a joint activity of a teacher and a student. The authors proposed a model for the development of research activities of students in the learning process, and empirically tested its effect, which confirmed the hypothesis. However, during the experimental phase, some limiting factors were identified.

Published: June 2021

The problems of the growth of public debt affect an increasing number of states in the modern world. Most countries record a significant shortage of their resources when making domestic investments and cover the state budget deficit and carry out socio-economic transformations. This lack of funds led to the formation of an economic debt system. At the same time, with the liberalization and globalization of financial markets, there will be an increase in the dependence of national economies on external replenishment. When carrying out economic transformations, most of the modern world countries resort to using external and internal sources of financing.The Kyrgyz Republic is no exception to this rule and today is largely dependent on external funding from foreign donors. At the same time, the lack of a consistent policy in attracting and using external and internal financial resources has led to the formation of significant external debt, which does not allow for economic transformations to ensure the country’s economic security. As a result of this study, recommendations were formed for the Ministry of Finance of the Kyrgyz Republic, which proposes a balanced policy of attracting expensive foreign loans to reduce the debt burden. In this study, the principles of dialectical logic, the unity of the logical and the historical, and generally scientific methods of cognition were used. Analysis, synthesis, consistency, special comparisons, groupings, classifications, generalization can be distinguished.

The need for systemic changes in vocational education is considered since the sphere of higher education is in dire need of professionals capable of developing their students, mastering new educational technologies and new pedagogical and administrative tools. The authors reviewed the main methodological approaches and substantiated the use of the synergetic approach to finding ways to improve vocational education. As such a path, the authors proposed a synergy of a personal learning environment along with the correct motivation of students. The authors clearly showed the mechanism of the personal learning environment and the place of each of its participants and proposed a possible variant of the task for the student in this environment and the criteria for its assessment.

Authors:   Sanatorio El Carmen, Salta, Argentina., Virgili Agustín , Wendichansky Carlos , Maroni Rodrigo
Published: June 2021

Left-sided gallbladder (LSGB) is a rare bile duct abnormality, usually found during a cholecystectomy. Symptoms usually do not differ from those of a normally positioned gallbladder, making the preoperative diagnosis extremely uncommon. We report the case of an acute cholecystitis in a patient whit LSGB, safely managed with laparoscopic surgery. A 24-year-old male patient was admitted to our institution with clinical and radiological signs of acute cholecystitis. The intraoperative finding of an acute cholecystitis in a LSGB made us modify ports positioning and a cholangiograhy was done by direct puncture of the gallbladder before hilum dissection. After the cystic duct was identified, a transcystic cholangiography was performed which confirmed a complete and clear bile duct anatomy and laparoscopic cholecystectomy was safely completed. The intraoperative finding of a LSGB makes the surgeon change some aspects of the usual technique to perform a safe cholecystectomy as LSGB significantly increases the risk of common bile duct injuries. Meticulous dissection of the gallbladder hilum to achieve a critical view of safety and the systematic use of intraoperative cholangiography are extremely important to perform a safe laparoscopic cholecystectomy.
La hernia umbilical en el paciente cirrótico: ¿tratamiento conservador o cirugía?
Authors:   Servicio de Cirugía General Hospital Pablo Soria. Jujuy. Argentina, Cano Carlos A. , Arias Abraham R.
Published: June 2021

Background: Background: Ascites is a common complication in patients with cirrhosis, and elevated intraabdominal pressure can lead to the development of abdominal wall hernias, particularly in patients with latent umbilical defects. Objectives: The aim of this study was to report the incidence and benefits of elective surgery for the management of umbilical hernias in cirrhotic patients with ascites. Material and methods: Between January 2015 and January 2019 15 patients with symptomatic umbi- lical hernia underwent elective surgery in a public hospital; 100% were men with a history of alcoho- lism and were hospitalized due to liver cirrhosis. The defect was closed, and a polypropylene mesh was placed in the supra-aponeurotic plane in most cases. Results: The preoperative risk was estimated using the Child-Pugh score. Ascites was evacuated in all the cases. Patients were followed-up every 30 days during the first 6 months and then twice a year. There were no hernia recurrences. Two patients were lost to follow-up 12 months after surgery and 1 patient died 9 months after the procedure due to progression of cirrhosis. Conclusions: Patients with liver cirrhosis and umbilical hernia should undergo elective surgery. Watchful waiting is associated with higher risk of hernia rupture and high morbidity and mortality.

Two-stage liver resections were described to increase the resectability of liver tumors in patients with insufficient future liver remnant. The ALPPS procedure, described in 2011, has represented a breakthrough in the field of hepato-pancreato-biliary surgery. This technique accelerates the hypertrophy of the future liver remnant and reduces the interval between the two surgeries compared with previous techniques. ALPPS has gained popularity rapidly, with more than 1200 patients included in the world registry. Recommendations about indications, patient selection and surgical standardization have been discussed twice in international expert meetings. Although ALPPS has proven to be superior in terms of resectability (80-100% versus 60-90% of twostage hepatectomy), its rapid implementation has been punished with high morbidity and mortality reaching up to 40% and 9%, respectively, in the published series. The current evidence on the possible benefits and disadvantages is mainly based on observational studies. We present a historical review, describing the different technical modifications that have been carried out since its description, with a rigorous review in terms of morbidity, mortality, and oncological outcomes.

Published: June 2021

Background: Learning complex tasks in surgical requires the coordination and integration of technical and non-technical skills have an impact on the performance of work teams. Objective: The aim of this study is to report the results of a simulation-based educational strategy for training in complex surgical skills considering the participants’ perceptions. Material and methods: In 2019, 10 healthcare professionals participated in a 20-hour course divided in 6 hours of online training and 14 hours of onsite training. The strategy designed included the integration of case resolution activities, role-playing, practice with synthetic and virtual simulators and high-fidelity simulation. At the end of the course, a questionnaire was administered to explore participants’ perceptions on what they had learned and on their attitude changes. Results: Fifty percent of the participants perceived their skills and knowledge improved at the end of the course compared with their perception at the beginning of the course while 80% perceived the impact of the course on their professional activity was good or excellent. All the participants agreed with the need for improving non-technical skills. The experience was rated as positive or very positive by all participants, who were eager to repeat it. Conclusion: The participants’ perceptions of this educational program demonstrates that this method is highly accepted. Raising awareness of non-technical skills during the reflection stage suggests the need for changes in attitude and in self-perception of efficacy. We believe that simulation-based training offers the possibility of improving the overall performance of the surgical team. Future studies should focus on this goal.
La base científica de los protocolos ERAS®
Authors:   School of Medical Sciences Dept of Surgery Örebro University Hospital & Örebro University. Suecia, Ljungqvist Olle
Published: June 2021

In this paper the principles of Enhanced Recovery After Surgery (ERAS) and how it is rooted in the medical sciences is reviewed and how ERAS has been developed by the ERAS Study Group and later by the ERAS®Society (www.erassociety.org). ERAS represents a formula for developing perioperative care pathways for patients undergoing surgery based on the medical literature. Expert groups review the medical literature and assembles care elements that have scientific data to show beneficial effects for recovery. By assembling multiple care elements all shown to improve outcomes, a Guideline is created from which a care pathway can be built. The Guideline is later tested in clinical practice to evaluate its effectiveness by studying compliance to the guideline care elements related to key clinical outcomes. Several ERAS®Society Guidelines have been proven to improve outcomes both with regard to complications and in hospital recovery and discharge. A growing number of reports are showing an association between improved compliance to guidelines and long term survival after surgery. Another aspect of the science behind ERAS are studies suggesting that the clinical effects are achieved by modulating various aspects of the surgical stress responses.

Usaha Mikro, Kecil, dan Menengah (UMKM) digambarkan sebagai sektor yang mempunyai peranan yang sangat penting dalam pembangunan di Indonesia. Pada Usaha Mikro, Kecil, dan Menengah (UMKM) perlu dilakukan pemberdayaan dan dikembangkan secara terus menerus dengan berusaha mengurangi kendala yang dialami Usaha Mikro, Kecil, dan Menengah (UMKM), sehingga mampu memberi kontribusi lebih maksimal terhadap peningkatan kesejahteraan masyarakat. Mayoritas permasalahan yang dialami oleh pelaku UMKM adalah belum dapat memisahkan antara catatan keuangan pribadi dan bisnis dan masih rendahnya pemahaman akan analisis laporan keuangan sehingga dibutuhkan keterampilan akuntansi untuk mengatasi hal tersebut.  Peranan Sistem Informasi Akuntansi untuk usaha kecil menengah (UKM) tidak jauh berbeda dengan yang sudah diaplikasikan pada perusahaan – perusahaan besar. Peranan Sistem Informasi Akuntansi bisa dijadikan dasar untuk pengambilan keputusan yang bisa diandalkan dalam kegiatan Usaha Mikro, Kecil, dan Menengah (UMKM). Penerapan Sistem Informasi Akuntansi memudahkan pelaku bisnis dalam pengambilan keputusan pengembangan pasar, penetapan harga, penyusunan laporan keuangan sesuai standar akuntansi, dan lain sebagainya. Dengan tersedianya pencatatan keuangan yang sesuai dan dilandasi penerapan sistem informasi akuntansi dapat memudahkan para pelaku UMKM untuk mengakses pembiayaan baik yang bersumber dari pemerintah maupun pihak kreditur (Bank) untuk perkembangan bisnisnya. Tujuan pengabdian kepada masyarakat ini untuk memberikan pengetahuan dasar mengenai sistem informasi akuntansi agar manajemen keuangan para pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) semakin baik.

Haploids are the value initial materials in corn breeding. However, spontaneous frequency of their appearance is about 0.01%. Due to selection and task-oriented breeding, researchers of the Genetic Department and the Department of Genetic and Reproductive Biology of the Saratov StateUniversity obtained homozygotic lines predisposed to parthenogenesis, autonomous endospermogenesis, androgenesis, polyembriony: АТ-1; АТ-3 (АТ – Apomictic Tyrnova); АPО-3 (line obtained from matriclinous haploid of a line АТ-3). We developed new genetically marked corn lines АТТМ using lines АТ-1 and ТM. Estimation of haploidy frequency was conducted in the field and laboratory conditions. There were conducted caryological and cytoembryologic analyses of the newly developed lines.
Impact of shift work on excessive daytime sleepiness among healthcare professionals and its association with medical incidents: A review
Authors: Tiwari Vaishali , Patil Hanumanthrao Chadershekar , Patil Rajesh Kumari , Gahlot Shivani
Published: June 2021

Sleep disorders, especially excessive daytime sleepiness (EDS), is a common complaint among medical professionals such as physicians and nurses. EDS is associated with decreased level of alertness in everyday life and thus leads to road accidents, workspace errors, and lack of concentration in people. We reviewed the literature to know the influence of shift work in the development of EDS and to scrutinize the relation between EDS and medical incidents. In association with EDS, shift work is defined as major risk factors. As health-care professionals are regularly involved in shift work to complete the 24 h services, they were more prone to experience EDS and may cause occupational incidents. Even though it is apparent that working in long shifts leads to sleep disorders, as the body clock is unbalanced, ample or apt research is required to collect reliable evidence. Various studies have reported occupational errors among nurses on comparatively longer work hours like drug administration errors, needlestick injuries, and operational errors in the past 12 months. In conclusion, these variables, that is, shift work, EDS, and occupational errors are directly related to each other. Further studies are required to explore the scenario between these factors.
Barium Defecating Proctography and Dynamic Magnetic Resonance Proctography: Their Role and Patient’s Perception
Authors: Korula Deepa Rebecca , Chandramohan Anuradha , John Reetu , Eapen Anu
Published: June 2021

Objectives:

The objectives of the study were to compare the imaging findings and patient’s perception of barium defecating proctography and dynamic magnetic resonance (MR) proctography in patients with pelvic floor disorders.

Material and Methods:

This is a prospective study conducted on patients with pelvic floor disorders who consented to undergo both barium proctography and dynamic MR proctography. Imaging findings of both the procedures were compared. Inter-observer agreement (IOA) for key imaging features was assessed. Patient’s perception of these procedures was assessed using a short questionnaire and a visual analog scale.

Results:

Forty patients (M: F =19:21) with a mean age of 43.65 years and range of 21–75 years were included for final analysis. Mean patient experience score was significantly better for MR imaging (MRI) (p < 0.001). However, patients perceived significantly higher difficulty in rectal evacuation during MRI studies (p = 0.003). While significantly higher number of rectoceles (p = 0.014) were diagnosed on MRI, a greater number of pelvic floor descent (p = 0.02) and intra-rectal intussusception (p = 0.011) were diagnosed on barium proctography. The IOA for barium proctography was substantial for identifying rectoceles, rectal prolapse and for determining M line, p < 0.001. There was excellent IOA for MRI interpretation of cystoceles, peritoneoceles, and uterine prolapse and substantial to excellent IOA for determining anal canal length and anorectal angle, p < 0.001. The mean study time for the barium and MRI study was 12 minutes and 15 minutes, respectively.

Conclusion:

Barium proctography was more sensitive than MRI for detecting pelvic floor descent and intrarectal intussusception. Although patients perceived better rectal emptying with barium proctography, the overall patient experience was better for dynamic MRI proctography.

Published: June 2021

Heterometallic Anderson wheels of formula [(VIVO)2MII5(hmp)10Cl2](ClO4)2·2MeOH (M = Ni, 1; Co, 2) have been synthesised from the solvothermal reaction of M(ClO4)2·6H2O and VCl3 with hmpH (2-(hydroxymethyl)pyridine). The metallic skeleton describes a centred hexagon, with the two vanadyl ions sitting on opposing sides of the outer ring. Magnetic susceptibility and magnetisation measurements indicate the presence of both ferromagnetic and antiferromagnetic exchange interactions. Theoretical calculations based on density functional methods reproduce both the sign and strength of the exchange interactions found experimentally, and rationalise the parameters extracted.
Morita-Baylis-Hillman Reaction. A Caveat
Authors: Yadav Veejendra
Published: June 2021

It is an oversight to consider that a Lewis base such as a trialkylamine adds to an activated alkene in conjugate fashion to generate an enolate as a 1,5-zwitterion, which next reacts in aldol fashion with an electrophile such as an aldehyde to move on further through other events to the Morita-Baylis-Hillman product. It is demonstrated from computational investigations that the union of trialkylamine and activated alkene leads possibly to a very low level charge-transfer entity, wherein the p-electron density of the alkene has little perturbed to call it an enolate in the conventional sense. It is suggested to consider the aldol reaction as the first step of the Morita-Baylis-Hillman reaction and arrive at the corresponding transition state structure directly from the three entities.

The exciton dynamics of 6,13-bis(triisopropylsilyl-ethynyl) pentacene is investigated to determine the role of excimer and aggregate formation in singlet fission in high concentration solutions.

Photoluminescence spectra were measured by excitation with the evanescent wave in total internal reflection, in order to avoid reabsorption effects. The spectra over nearly two magnitudes of concentration were near identical, with no evidence for excimer emission. Time-correlated single-photon counting measurements confirm that the fluorescence lifetime shortens with concentration, and we obtain a bimolecular rate constant of $4\times10^9$\,M$^{-1}$s$^{-1}$ in chloroform. The observed rate constant grows at high concentrations. This effect is modelled in terms of the hard sphere radial distribution function.

NMR measurements confirm that aggregation takes place with a binding constant of between 0.14 and 0.43M$^{-1}$. Transient absorption measurements are consistent with a diffusive encounter mechanism for singlet fission, with hints of more rapid singlet fission in aggregates at the highest concentration measured.

These data show that excimers do not play the role of an emissive intermediate in exothermic singlet fission in solution, and that while aggregation occurs at higher concentrations, the mechanism of singlet fission remains dominated by diffusive encounters.

Published: June 2021

Automation and optimization of chemical systems require well-inform decisions on what experiments to run to reduce time, materials, and/or computations. Data-driven active learning algorithms have emerged as valuable tools to solve such tasks. Bayesian optimization, a sequential global optimization approach, is a popular active-learning framework. Past studies have demonstrated its efficiency in solving chemistry and engineering problems. We introduce NEXTorch, a library in Python/PyTorch, to facilitate laboratory or computational design using Bayesian optimization. NEXTorch offers fast predictive modeling, flexible optimization loops, visualization capabilities, easy interfacing with legacy software, and multiple types of parameters and data type conversions. It provides GPU acceleration, parallelization, and state-of-the-art Bayesian Optimization algorithms and supports both automated and human-in-the-loop optimization. The comprehensive online documentation introduces Bayesian optimization theory and several examples from catalyst synthesis, reaction condition optimization, parameter estimation, and reactor geometry optimization. NEXTorch is open-source and available on GitHub.
