Transfer Hydrogenation Reactions by Using Simple Biomass Alcohols as Hydrogen
Sources
Authors: Qie Xuan , Khan Ruhima , Fan Baomin 
Published: September 2022

Abstract:
The reduction of different unsaturated compounds by transfer hydrogenation (TH)
has emerged as a more efficient methodology than the classical method of using the molecular
hydrogen in industry and laboratory. Transfer hydrogenation is more advantageous in terms of
safety and convenience. Alcohols, formic acid, esters, H2O, etc. are the common molecules
that are used as a hydrogen donor in the transfer hydrogenation reaction. Primary alcohols,
namely methanol and ethanol were less explored as a hydrogen source in the TH reaction,
probably due to the formation of aldehyde after dehydrogenation of these alcohols, which are
more reactive and may undergo side reactions. However, methanol and ethanol are cheap,
easily available, and easily handled compounds. They can be easily obtained from biomass,
coal, etc. Because of these advantages, chemists became more interested in the application of
methanol and ethanol as hydrogen sources in the transfer hydrogenation reaction. In this review, we present an
overview of the work reported by different groups on the transfer hydrogenation reactions with methanol and ethanol
as hydrogen sources.

Authors: Chen Si , Lin Yuying , Zuo Shufang , Wang Ziyu , Liang Jinghong , Jiang Zheng , Xu Yue , Wang Peiyu , Jing Xiuchen , Lin Lu 
Published: September 2022

Objectives:
This study aimed to explore whether bilingual older adults had a cognitive advantage over their monolingual counterparts, and validate the influence of cognition-related (participants’ cognitive condition, the cognitive domain assessed), and bilingualism-related factors (second language proficiency, frequency of use, acquisition time, and immigration status of participants)on the cognitive advantage of bilingualism.

Methods:
Through a systematic search of nine databases (Web of science, PubMed, Elsevier Science Direct, Cochrane Library, Embase, PsycINFO, CNKI, VIP and Wanfang) from the inception to April, 2021, observational studies with bilingual and monolingual older adults as participants and cognitive function scores as outcome measures were included. Two reviewers independently completed the selection and methodological quality assessment of studies using the JBI cross-sectional study quality evaluation tool, and used a pre-designed table for data extraction and sorting.

Results:
Fourteen studies with 51 tasks were included, involving 3737 participants (bilingual group: 1695, monolingual group: 2042). The overall results of the meta-analysis showed that bilingualism had a small cognitive advantage over monolingualism in older adults [SMD=0.23, 95%CI (0.07, 0.38), P=0.004]. In addition, the subgroup analyses indicated that factors such as participants’ cognitive condition, the cognitive domain assessed, second language proficiency, acquisition time, and immigration status of participants had an impact on the cognitive advantage of bilingualism in older adults.

Conclusion:
Bilingualism had a mild cognitive advantage over monolingualism in older adults, which was more prominent in older adults with mild cognitive impairment than in cognitively healthy ones, more evident in global cognitive function and inhibitory control than in other individual cognitive domains, and might be influenced by the proficiency and acquisition time of second language as well as the immigration status of older adults.

Authors: Ramos-Casallas Alejandro , De Avila Juliette , Chaparro‐Sanabria Andrea , Choueka Philippe Chalem , Bello-Gualtero Juan Manuel , Chila-Moreno Lorena , Pacheco-Tena César , Bautista-Molano Wilson , Romero-Sánchez Consuelo 
Published: September 2022

Background:
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by joint inflammation and destruction.

Objective:
Establish the association between Porphyromonas gingivalis (P. gingivalis) infection, body mass index (BMI), joint involvement, and serum adipokines in first-degree relatives (FDR) of patients with rheumatoid arthritis (RA).

Methods:
The cross-sectional study evaluated 124 FDR and 124 healthy controls (HC). The clinical examination included joint and radiographic evaluation and calculation of BMI. Serum adipokine levels were measured (leptin, vaspin, adiponectin, resistin, and adipsin), as were the erythrocyte sedimentation rate, C-reactive protein, and anti-citrullinated protein antibodies. Investigations were performed to detect P. gingivalis, and anti-P. gingivalis antibodies. Statistical analyses were per-formed to confirm associations.

Results:
Leptin levels in FDR were associated with BMI >25 (OR, 2.64; 95%CI, 1.17-5.97; P=0.019), radiographic damage (Simple Erosion Narrowing Score [SENS])/hands, total SENS, and joint space narrowing in feet (P=0.037, 0.026, 0.020, respectively). FDR had more tender joints (P=0.018); this finding was associated with high levels of leptin and resistin and low levels of adip-sin (P=0.040, 0.040, and 0.019, respectively).
The presence of P. gingivalis was related to FDR, low levels of adipsin, resistin, adiponectin, and a trend toward higher levels of leptin (P=0.002, 0.001, 0.003, and 0.060, respectively), whereas anti-P. gingivalis antibodies were related to low levels of adipsin (P=0.001).

Conclusion:
In FDR, serum adipokine levels were associated with overweight and the presence of P. gingivalis. Adipokine levels were also associated with joint involvement. Hence, adipokines may be involved in the pathogenesis of RA in FDR and warrant further investigation.

of Pulmonary Nodules Guided by Computed Tomography before Thoracoscopic
Surgery
Authors: Liu Yinghui , Hou Zhonghui , Wu Ke , Zhu Yanjun , Wang Huaiyu , Han Yong 
Published: September 2022

Objective:
The study aims to conduct lung cancer screening by low-dose CT to identify the
nature of the pulmonary nodule. The purpose of this study was to evaluate the role of preoperative
medical EC glue localization of pulmonary nodules of uncertain nature by minimally invasive surgical
resection.

Methods:
From December 2017 to December 2019, 18 patients (12 women, 6 men; median age: 54
years)with pulmonary nodules were located using medical EC glue under the guidance of preoperative
CT and then resected under video thoracoscopy at Air Force Medical Center of PLA. The clinical
characteristics were retrospectively collected to evaluate the effectiveness, safety and feasibility of the
operation.

Results:
The mean value of the maximum diameter of pulmonary nodules on CT images before the
operation was 10.8 mm. The average depth was 10.3 mm (1.0-39.5 mm). Among 18 nodules, 8 were
pure ground glass nodules, 3 were solid nodules, and 7 were partial solid nodules. The diagnosis rate of
medical glue localization under the guidance of CT after the operation was 100%. Postoperative pathological
diagnosis showed that there were 10 cases of primary lung adenocarcinoma, 1 case of invasive
lung adenocarcinoma, 3 cases of adenocarcinoma in situ, 1 case of metastatic adenocarcinoma, and 3
cases of benign nodules. No obvious serious complications were found after localization.

Conclusions:
This study suggests that CT-guided percutaneous medical EC glue localization is a reliable,
safe, feasible and practical method for undiagnosed pulmonary nodules and can significantly improve
the rate of resection of small pulmonary nodules. Furthermore, it was considered to be more
reasonable to remove pulmonary nodules and maximize the preservation of lung function.

Learning with Application to Image Segmentation and Medical Diagnosis
Authors: Ye Yinghai , Chen Huiling , Pan Zhifang , Xia Jianfu , Cai Zhennao , Heidari Ali Asghar 
Published: September 2022

Background:
Moth-flame optimization will meet the premature and stagnation phenomenon when encountering difficult optimization tasks.

Objective:
To overcome the above shortcomings, this paper presented a quasi-reflection moth-flame optimization algorithm with refraction learning called QRMFO to strengthen the property of ordinary MFO and apply it in various application fields.

Method:
In the proposed QRMFO, quasi-reflection-based learning increases the diversity of the population and expands the search space on the iteration jump phase; refraction learning improves the accuracy of the potential optimal solution.

Results:
Several experiments are conducted to evaluate the superiority of the proposed QRMFO in the paper; first of all, the CEC2017 benchmark suite is utilized to estimate the capability of QRMFO when dealing with the standard test sets compared with the state-of-the-art algorithms; afterward, QRMFO is adopted to deal with multilevel thresholding image segmentation problems and real medical diagnosis case.

Conclusion:
Simulation results and discussions show that the proposed optimizer is superior to the basic MFO and other advanced methods in terms of convergence rate and solution accuracy.
Combating the COVID-19 Pandemic Using 3D Printed PPE: Challenges and Recommendations
Authors: Amir Amaar , Amir Baraa 
Published: September 2022

Background:
The World Health Organization declared COVID-19 a pandemic in March of 2020. As traditional respiratory personal protective equipment (PPE) was in severe shortage, communities turned to 3D printing to provide printed PPE alternatives; however, certain hurdles need to be addressed to ensure the safety of users.

Objective:
One main consideration when dealing with 3D printed parts is the presence of pores. Several studies have found the diameter of these pores to range widely from as little as 10µm to over 150 µm, making them larger than the droplets and nuclei through which the virus is transmitted.

Methods:
Researchers found that altering print settings, such as increasing the extrusion multiplier, may decrease the size and number of these perforating pores. Other challenges include the variable reproducibility of printed PPE, which may be remedied through printer calibration. Storage and sterilization are also a challenge as most 3D printed plastics do not tolerate disinfection methods, such as autoclaves. The use of chemical disinfectants is recommended instead. The rigidity of printed plastics may compromise the fit of masks for varying users. Using 3D scanning may provide personalized masks that seal appropriately.

Results:
One final issue is the prolonged interaction with 3D printers of inexperienced users, predisposing them to the respiratory tract and skin irritation; thus, adequate ventilation and protection are mandatory.

Conclusion:
Documenting the benefits and drawbacks of this form of PPE production carries great significance in light of the ongoing COVID-19 pandemic, as well as any future public health emergencies.
A Text-Based Smoking Cessation Intervention for Sexual and Gender Minority Groups: Protocol for a Feasibility Trial
Authors: Tami-Maury Irene , Klaff Rebecca , Hussin Allison , Smith Nathan Grant , Chang Shine , McNeill Lorna , Reitzel Lorraine R , Shete Sanjay , Abroms Lorien C 
Published: September 2022

Background
Smoking among sexual and gender minority (SGM) groups, which include lesbian, gay, bisexual, transgender, and queer individuals, has been reported to be highly prevalent. This is attributed to several factors, including minority-specific stress and targeted tobacco marketing. Therefore, this population is at an increased risk for tobacco-related diseases. SMS text messaging programs have been found to be effective for smoking cessation and appeal to traditionally hard-to-reach populations over other interventions. It has also been suggested that targeted and tailored interventions could be more effective among SGM smokers because they can be designed to assure a safe, validating health care environment that enhances receptivity to cessation.

Objective
The aim of this study is to develop SmokefreeSGM, a text-based smoking cessation program tailored to and tested among SGM smokers.

Methods
The study consists of three phases, culminating in a feasibility trial. In Phase 1, our research team will collaborate with a Community Advisory Board to develop and pretest the design of SmokefreeSGM. In Phase 2, the tailored text messaging program will be beta tested among 16 SGM smokers. Our research team will use a mixed-methods approach to collect and analyze data from participants who will inform the refinement of SmokefreeSGM. In Phase 3, a feasibility trial will be conducted among 80 SGM smokers either enrolled in SmokefreeSGM or SmokefreeTXT, the original text-based program developed by the National Cancer Institute for the general population. Our research team will examine recruitment, retention, and smoking abstinence rates at 1-, 3-, and 6-month follow-up. Additionally, a qualitative interview will be conducted among 32 participants to evaluate the feasibility and acceptability of the programs (SmokefreeSGM and SmokefreeTXT).

Results
This study received approval from The University of Texas Health Science Center at Houston Committee for the Protection of Human Subjects to begin research on August 21, 2020. Recruitment for the beta testing of SmokefreeSGM (Phase 2) began in January 2022. We estimate that the feasibility trial (Phase 3) will begin in September 2022 and that results will be available in December 2023.

Conclusions
Findings from this research effort will help reduce tobacco-related health disparities among SGM smokers by determining the feasibility and acceptability of SmokefreeSGM, an SGM-tailored smoking cessation intervention.

La tabla periódica de los elementos, los isótopos y la ciencia forense
Authors: Martínez Carrillo Miguel Ángel , Solís Rosales Corina 
Published: September 2022

<p>El uso de isótopos ha cobrado relevancia en ciencias gracias a la aparición de espectrómetros de masas cada vez más compactos y asequibles. Las aplicaciones de los análisis isotópicos se han convertido en una herramienta rutinaria en áreas como ciencias de la tierra, biología y ciencia forense. Por lo que el tema de los isótopos cobra relevancia en el ámbito de la enseñanza de química para estudiantes de todas esas áreas. Toca a los profesionales de la didáctica de la química para no químicos, encontrar las mejores formas de abordar el tema y presentarlo a los alumnos. El reto no es difícil, es un tópico de actualidad, interesante y con aplicaciones fascinantes en forense. Se propone abordar la enseñanza de los isótopos desde la perspectiva histórica dentro del tema de Tabla Periódica, quizá como parte de la solución a uno de los problemas surgido durante la construcción del sistema periódico: los pesos atómicos. En este documento se hace referencia al peso atómico estándar como peso atómico por razones históricas y porque entre las diversas variantes de la noción de peso atómico utilizadas en ciencias, el peso atómico estándar es el más común y práctico. El propósito de este documento es motivar a los profesores e investigadores forenses a explorar el estudio de los isótopos, eliminar el falso concepto de que todos los isótopos son radiactivos y que conozcan algunas de las aplicaciones de las técnicas isotópicas.</p><div> </div>
Curating Russia: The Shchukin Collection, Nationalism, and Border Crossing from Lenin to Putin
Authors: Rasmussen Leah 
Published: September 2022

Russia’s relationship with nation is marred by contradictions that stem from its place in comparison to the West. Cultural nationalism in artistic production originated with the arrival of the Peredvizhniki [Wanderers] in the 1870s. Moscow merchant Pavel Tretyakov, in collecting Russian and European art, openly embraced a nation that encompassed Western ideas in conjunction with distinctly Russian themes. The unparalleled collecting of French modern art by Moscow merchants Sergei Shchukin and Ivan Morozov in the early 20th century continued this embrace. The nature of their collected paintings produced shockwaves in late tsarist and Soviet society and politics before being inculcated into Russian national identity in the 21st century. This article explores the life of Henri Matisse’s The Dance (1909), commissioned by Sergei Shchukin. It follows the work across time and regimes as it assumes pride of place in not only Russia’s national collections but also within its identity. Through a focus on the 2008 exhibition From Russia at the Royal Academy of Arts in London, this article examines Russia’s relations and protection of this work to understand, why even as the country seeks to define itself once more actively through its opposition to the West, their cultural diplomacy speaks to an openness built on a transnational history of the most prized works in their national collections.
South Korea in Reconstructing Masculinity as Brand Image of the State’s Economic Diplomacy
Authors: Azizah Nur , Dwiyanti Ainun 
Published: September 2022

By applying the theory of Economic Diplomacy by Rana and Chatterjee, Public Diplomacy by McClory and State Identity by Maxym Alexandrov, the main purpose of this study was to analyze the reasons behind South Korea’s promotion of soft masculinity through their means of public diplomacy, such as K-Pop and Korean drama. Particularly in South Korea, ideas about how to look good as ‘a man’ are changing attitudes and also influencing the world. The study has applied phenomenology methodology and qualitative research methods to understand the contemporary international relations phenomenon which are soft masculinity and economic diplomacy. The unit of analysis examined as the subject is ‘South Korean government’ and the unit of explanation were the driving factors of why South Korea promotes soft masculinity. The data were taken from the secondary sources such as various books, journals, reports, as well as documents from different relevant websites and a comprehensive and systematic analysis were applied. It was found that soft masculinity as an image that is promoted through the public diplomacy tool of South Korea, such as K-Pop creates the appeal of the country towards the global audience as it is a rarity. South Korea has become the front liner of soft masculinity by incorporating the image through its economic diplomacy. This research further reveals that South Korea promotes soft masculinity in its K-Pop product because the country is utilizing the uniqueness of soft masculinity as its brand image to enhance its economic diplomacy for its cosmetic industry

Authors: Campione Roger 
Published: September 2022

Las aplicaciones basadas en la inteligencia artificial abren la posibilidad concreta de replicar en máquinas una capacidad de razonamiento similar a la humana, otorgando a estas la facultad de construir representaciones no programadas gracias al aprendizaje proporcionado por algoritmos y Big Data. El abanico de inevitables dilemas que la aplicación de estos sistemas plantea en muchos ámbitos de la vida social resulta sobrecogedor y la dimensión normativa de la inteligencia artificial es evidentemente una de las más delicadas, por los intereses y principios que hay en juego. Se introducen aquí algunas consideraciones de orden iusfilosófico sobre las relaciones entre el derecho, la política y la vigilancia tecnológica.

Abstract
In order to consolidate the effect of classroom teaching and broaden students’ thinking, stimulate students’ interest in learning, avoid forgetting more and more, so that students actively explore knowledge. The author proposes an adaptive memory model based on Ebbinghaus’ forgetting curve theory. Firstly, the relationship between the mathematical equation of memory curve and Ebbinghaus forgetting curve theory is introduced. Select the forgetting curve fitting function, and then define the adaptive memory model, the software divides the user’s initial cognition of words into three types: cognition, vagueness, and ignorance, the average memory times of these three types of content are counted separately, finally, the average memory times of the three types of content are comprehensively averaged, finally, a comparative experiment is carried out based on the intelligent memory model of the Ebbinghaus forgetting curve. The results show that while not affecting the memory effect, using the intelligent memory model, the number of memories is reduced by 37.12% compared with the New Oriental memory method, using the adaptive memory model reduces the number of memories by 43.35% compared to the New Oriental memory method. The experimental results show, the adaptive memory model further saves 6.31% of memory times compared to the intelligent memory model, not only has good adaptability to each user’s memory situation, it also further improves memory efficiency. From this it can be seen that, university ideological and political learning model based on the mathematical equation of statistical memory curve: The adaptive memory model has certain reliability and feasibility.

Published: September 2022

Abstract
In order to explore the fractional differential equations in accounting informatization financial software, the author proposes a system for fractional diffusion wave equations and fractional differential equations, two numerical algorithms with higher precision are given, and the amount of computation is reduced at the same time. First, based on the equivalent integral form of the time fractional diffusion wave equation, using the fractional echelon method and the Crank-Nicolson method, for the time fractional diffusion wave equation, a finite difference scheme is designed, this format has second-order accuracy in both the temporal and spatial directions and is computationally stable. Numerical examples verify the accuracy and effectiveness of this format. Then when dealing with the initial value problem of fractional differential equations with Caputo derivative operator, convert it to the equivalent Voltera integral equation system, an initial approximate solution is obtained by a low-order method, derive the residual and error equations, the idea of applying the stepwise correction of spectral delay correction improves the numerical accuracy of the solution, at the same time, the Richard Askey integral equation is used to reduce the amount of calculation. At last, the high precision and effectiveness of the new method are verified by numerical experiments. Experiments show that: Starting from the equivalent integral form of the fractional diffusion wave equation, a second-order finite-difference scheme of the fractional-order diffusive wave equation is constructed, through numerical experiments, it is verified that the scheme has good accuracy and efficiency. In numerical solution, discrete integral equations have better numerical stability than differential equations, therefore, the format also has better stability. When taking different fractional derivative indices a=1.5 and a=1.8, it can be seen that the difference format constructed by the author, in the time direction, has second-order precision, as expected.
