Multi-Agent Task Allocation with Interagent Distance Constraints
Authors: Choi Euihyeon , Chang Woohyuk
Published: November 2023

In this paper, we consider the task allocation problem for autonomous agents where the distances between any two agents should always be less than a predetermined value. To easily tackle the problem, we introduce a novel concept referred to as a virtual task that helps to decouple the task allocation from the path planning in the joint task allocation and path planning problem. An overall task allocation procedure with two steps is proposed. After the virtual tasks are generated with preliminary clustering in the first step, tasks are clustered into groups and allocated to agents in the second step. To reduce the computational complexity of optimal clustering and task allocation, we propose a suboptimal method called the cluster-level traveling salesman problem (TSP). Numerical results show that the cluster-level TSP suffers only little performance degradation compared to the optimal method, even though its computational costs are dramatically reduced.

Published: November 2023

Background. The role of surgical management of calciphylaxis remains understudied. Objective. This article reports a case series and algorithmic approach to the multidisciplinary management of calciphylaxis. Methods. A single-center retrospective review of all adult patients with calciphylaxis treated surgically between January 2010 and November 2022 was performed. Results. Eleven patients met inclusion criteria. The average age was 50.9 years ± 15.8 SD, and most patients were female (n = 7 [63.6%]). Surgery was indicated for infection (n = 6 [54.5%]) and/or intractable pain (n = 11 [100%]). Patients underwent an average of 2.9 excisional debridements during their hospital course. Following the final excision, wounds were left open in 5 cases (29.4%), closed primarily in 4 (23.5%), and local flaps were used in 3 (27.3%). Postoperatively, the mean time to healing was 57.4 days ± 12.6. Complications included dehiscence (n = 1 [9.1%]), progression to cellulitis (n = 2 [18.2%]), osteomyelitis (n = 1 [9.1%]), and lower extremity amputation (n = 2 [18.2%]). Of the 6 patients alive at the time of healing, 5 (83.3%) were no longer taking narcotic medications. At an average follow-up of 26.4 months ± 34.1, 7 patients (63.6%) were deceased, with an average time to mortality of 4.8 months ± 6.7. Of the 4 remaining patients, 3 (75.0%) were ambulatory by their most recent follow-up visit. Conclusion. While the morbidity and mortality associated with calciphylaxis are substantial, surgical excision is effective in reducing pain and improving quality of life in patients with this end-stage disease. Wound care centers are uniquely equipped with a variety of medical and surgical specialists with experience in treating chronic wounds and thus facilitate an efficient multidisciplinary model.

Chiral, enantiopure Yb(III) complexes are able to emit circularly polarized luminescence (CPL) in the near infrared (NIR) wavelength region, quantified by the dissymmetry factor (glum). Due to crystal field splitting (CFS), the excited state 2F5/2 consists of three mj' sublevels, which are populated in accordance with the Boltzmann distribution. Consequently, room temperature CPL spectra are the sum of various - either positive or negative – contributions, that are practically impossible to quantify. Thanks to the use of an advanced setup enabling CPL measurements over a range of temperatures (300 to 4 K), the interrelation of CFS, glum and temperature was demonstrated on the example of a pair of enantiopure Yb(III) com-plexes. It was thereby confirmed that each mJ’ sublevel gives an independent contribution to the overall CPL spectrum. Hence, the CPL spectra of chiral lanthanide complexes were found to be indeed strongly temperature-dependent, as is the glum dissymmetry factor, as a consequence of the variation in thermal sublevel population. These results were additional-ly interpreted in the framework of multireference wave-function calculations.
Revisiting the Chemistry and Photophysics of 3-(N-Methylpyridinium-4-yl)Coumarins for Designing "Covalent-Assembly" and "Molecular Disassembly" Fluorescent Probes
Authors: GAUMERD Vincent , RENAULT Kévin , RENARD Pierre-Yves , ROMIEU Anthony
Published: November 2023

The constant need for high-performance aniline- or phenol-based fluorophores suitable for the construction of activity-based fluorescent probes, led us to study both synthesis and photophysics of under-explored C3-N-methylpyridinium-4-yl substituted 7-(dialkylamino)/7-hydroxycoumarins. Indeed, in the field of photoactive organic molecules, the positively charged N-alkylpyridinium-4-yl groups are often used as acceptor units to dramatically impact spectral features through promoting intramolecular charge transfer (ICT) process. They are also known as effective water-solubilizing and cell organelle (mitochondria) targeting moieties. The poor fluorescence efficiency of cationic 7-hydroxycoumarin derivatives in aqueous physiological conditions was highlighted and rationalized by the predominance of a neutral quinonoid form in such buffer medium. The ability of the excited singlet state (S1) of this neutral species to undergo intersystem crossing (ISC) to triplet state (T1) was partly supported by phosphorescence measurements of singlet oxygen (1O2). We took advantage of superior green-emissive properties of 7-(diethylamino)-3-(N-methylpyridinium-4-yl)coumarin to successfully design and validate a novel small-molecule fluorescent probe for the detection of alkaline phosphatase (ALP), based on the "covalent-assembly" principle. In last part of this study, a practical use of ortho-formylated 7-hydroxy-3-(N-methylpyridinium-4-yl)coumarin was considered with the synthesis of a Fe(III)-salen complex known to act as effective "molecular disassembly" probe for fluorogenic sensing pyrophosphate (PPi) ions in aqueous media, and through the promising approach recently proposed by the Zelder group (Chimia 2020, 74, 252-256).

Authors: Retamal Ferrada Lorena , Vega Melita , Orozco-Toro Jaime Alberto , Ávila Caroline
Published: November 2023

The Sustainable Development Goals (SDGs) linked to the 2030 Agenda have been widely accepted by public and private companies, with many choosing to incorporate them within the framework of their social responsibility initiatives. This research article aims to find out how the SDGs are reflected in corporate sustainability reports and in which business activities they stand out the most. To this end, using a sequential explanatory methodology, the authors analyzed 12 sustainability reports issued in 2021 by large companies in Colombia, Chile, and Ecuador to verify their alignment with the SDGs. The reports showed evidence of a diverse range of programs associated with at least three SDGs, thus highlighting the importance of fulfilling not only the needs based on each company’s field of expertise but also those of its audiences and the community in general. The most prevalent SDGs were “decent work and economic growth” (SDG 8) and “gender equality” (SDG 5), followed by “responsible consumption and production” (SDG 12). This paper contributes to a growing interest among academia in the research on sustainability communication evidenced in annual reports.

Published: November 2023

Background: Cigarette smoking follows a progressive pattern throughout the lifetime; most adult smokers started smoking during adolescence. Aim: To understand the cigarette smoking trajectories and their predictors among adolescents and young adults in the Islamic Republic of Iran. Methods: Using data from the Tehran Lipid and Glucose Study, we followed 1169 adolescents (12–18 years old) into their young adulthood (28–32 years old), from 2002 to 2016. We used cigarette smoking as the outcome variable for group-based trajectory modelling. After detecting the trajectories, we investigated the effects of independent variables, namely, individual employment; education; physical activity; and paternal smoking, employment and education, on the trajectories. We analysed the data using STATA version 16 and SPSS version 26. Results: Three trajectories were detected: non-smokers (79%), experimenters (12%) and escalators (9%). Boys were approximately 3 times (OR = 2.94, 95% CI: 2.32–3.24, P < 0.001) and 25 times (OR = 25.00, 95% CI: 23.92–26.08, P < 0.001), respectively, more likely than girls to be in the experimenter and escalator groups. Receiving a university education decreased the odds of being in the escalator trajectory for 18% (OR = 0.82, 95% CI: -0.04–0.96, P = 0.002) of the study participants. Employment after high school increased the odds by approximately two folds for the experimenter (OR = 2.00, 95% CI: 1.42–2.50, P = 0.01) and escalator (OR = 2.33, 95% CI: 1.33–2.93, P = 0.03) trajectories. Paternal smoking was associated with 1.88 and 2.23, respectively, increased odds of experimenting and escalating smoking among the adolescents. Conclusion: Iranian adolescents follow 3 cigarette smoking trajectories into young adulthood: non-smokers, experimenters and escalators. Male sex, employment after high school, and living with a smoker father were associated with unfavourable smoking patterns. Findings from this study provide valuable insights for designing targeted interventions to reduce cigarette smoking among adults and adolescents in the Islamic Republic of Iran.

Kerangka kerja tersebut memaparkan 16 keterampilan penting yang harus dimiliki anak agar dapat sukses di masa depan, salah satunya adalah kreativitas. Sayangnya, indeks kreativitas Indonesia masih berada di jajaran rendah negara-negara di dunia. Global Creativity Index (GCI) 2015 oleh Martin Prosperity Institute menempatkan Indonesia pada peringkat 115 dari 139 negara. Pembelajaran IPA sebagai pembelajaran yang esensial bagi siswa, harus tanggap mengenai hal ini dengan memfasilitasi perkembangan kreativitas siswa di dalamnya. Gamifikasi merupakan salah satu upaya dalam memantik ketertarikan, memacu motivasi, serta mendorong keterlibatan siswa (student engagement) pada proses pembelajaran. Banyak penelitian mengenai gamifikasi telah dilakukan dengan mengadopsi mekanika dan estetika permainan dalam pembelajaran dan secara umum berhasil meningkatkan motivasi serta hasil belajar siswa. Namun, keterkaitan antara penggunaan gamifikasi dalam pembelajaran dengan perkembangan kreativitas siswa belum banyak diteliti dan dibahas secara teori. Oleh karena itu, tulisan ini mencoba memaparkan kajian literatur mengenai bidang-bidang yang mampu diintervensi oleh gamifikasi sehingga dapat mengembangkan dan membangun kreativitas siswa.

This study was designed to identify and describe students’ metacognitive thinking process in solving compound polarity based on academic ability level. Two hundred and eighty-four high school students in Indonesia participated in the study. Students are classified into high, middle and low academic ability groups based on field notes, student academic data, compound polarity problem-solving test (CPPST) scores and teacher suggestions. Six selected students from each group were designated as research subjects and then interviewed in depth to explore their metacognitive thinking processes. CPPST answer sheets and interview transcripts were analyzed using summative content analysis and tested for validity by data triangulation. The results showed that the students with high and medium academic ability level carry out metacognitive thinking processes in the dimensions of planning, monitoring and reflection in solving compound polarity problems, where the metacognitive thinking processes of students with high academic ability are more varied than students with middle academic ability. Students with low academic ability only carry out the dimensions of planning and monitoring. Therefore, teachers need to train students' metacognitive skills in solving problems and get used to applying metacognitively in each given problem solving so that students are trained to solve problems systematically, carefully and thoroughly, and manage time properly in order to obtain the expected learning achievement.
