Cubane Pyrolysis: Scaling Bond Polarity with Universal Polynomials
Authors: Ayarde Henríquez Leandro , Guerra Cristian , Chamorro Eduardo
Published: June 2024

This study presents a novel methodological approach to elucidate the intricate multi-correlation between electron reorganizations, the most stable molecular configurations, and the topographical description of relevant chemical processes. In such a context, an in-depth reevaluation of the chemical bonding analysis underpinning the cubane pyrolysis mechanism, as reported by Seif et al. [RSC Adv., 2020, 10, 32730-32739] is achieved. A fold-cusp unified model of universal functions for scaling bond polarity is derived from this multi-nexus. The scaling revealed that bond polarity index values within the interval [0, 10-5] au correspond to the cusp unfolding, while the fold spans over a wider interval, [10-3, ∞) au. Contrary to previous observations, no cusp flag was detected upon re-examining single scissions and double formations/breakages of carbon-carbon bonds in the first step of the reaction mechanism (i.e., cubane to bicyclo[4.2.0]octa-2,4,7-triene), as demonstrated by the determinant of the Hessian matrix at all potentially degenerate critical points of the electron localization function along the intrinsic reaction coordinate. The transannular ring opening in the second elementary reaction (bicyclo[4.2.0]octa-2,4,7-triene to 1,3,5,7-cyclooctatetraene) is the only chemical process exhibiting cusp characteristics, underscoring the model’s reliability. The computed thermochemical dataset closely matches the experimental values, highlighting the robustness and accuracy of the derived insights.

Published: June 2024

Novel H-bond-rich iridium (III) complexes with different systems of cyclometalating ligands bearing the general formula [Ir(C^N)2(N^N)] were synthesized, characterized and their photophysical properties measured. The incorporated guanidine moieties allow us to introduce a hydrogen-bonding array for the formation of self-assembled iridium hydrogen-bonded systems. Through a series of UV-Vis binding studies we demonstrated the host-guest chemistry of these systems display high levels of colour tuneability. These hydrogen-bond interactions were also shown to have significant impacts on chromaticity, quantum yields and lifetimes with emphasis on energy transfer studies based on this second-sphere coordination approach.

Despite the success of first, second and third generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in treatment of non-small cell lung cancer (NSCLC) with classical EGFR mutations (L858R or Exon 19 deletions), disease progression often occurs due to the acquisition of additional mutations in the EGFR kinase domain that confer TKI resistance. Specifically, acquisition of both T790M and C797S resistance mutations results in an EGFR variant that is resistant to all approved EGFR TKIs. Herein, we report a physics-based computationally-driven lead identification approach which successfully identified structurally-unique imidazo[3.2-b]pyrazole derivatives as reversible inhibitors of EGFR classical mutations bearing both T790M and C797S. Importantly, they spare EGFR WT to avoid known EGFR WT-driven cutaneous toxicities. During profiling of imidazo[3.2-b]pyrazole derivatives, we elucidated the bioactivation mechanism causing CYP3A4/5 time-dependent inhibition (TDI) and found key modifications to suppress bioactivation and mitigate the TDI risk. Representative lead compound 31 inhibited EGFR L858R/T790M/C797S in biochemical assays with a Ki = 2.1 nM, and EGFR del19/T790M/C797S in a Ba/F3 cellular assay with a IC50 = 56.9 nM. Deuterated analog of 31 (38) demonstrated dose-dependent tumor growth inhibition in a Ba/F3 EGFR del19/T790M/C797S CDX model by 47% at 50 mg/kg BID and 92% at 100 mg/kg BID.

Porous solids can accommodate and release molecular hydrogen readily, making them attractive for minimizing the energy requirements for hydrogen storage relative to physical storage systems. However, H2 adsorption enthalpies in such materials are generally weak (−3 to −7 kJ/mol), leading to low capacities at ambient temperature. Metal–organic frameworks with well-defined structures and synthetic modularity could allow for tuning adsorbent–H2 interactions for ambient-temperature storage. Recently, Cu2.2Zn2.8Cl1.8(btdd)3 (H2btdd = bis(1H-1,2,3-triazolo-[4,5-b],[4′,5′-i])dibenzo[1,4]dioxin; CuI-MFU-4l) was reported to show a large H2 adsorption enthalpy of −32 kJ/mol owing to π-backbonding from CuI to H2, exceeding the optimal binding strength for ambient-temperature hydrogen storage (−15 to −25 kJ/mol). Toward realizing optimal H2 binding, we sought to modulate the π-backbonding interactions by tuning the pyramidal geometry of the trigonal CuI sites. A series of isostructural frameworks, Cu2.7M2.3X1.3(btdd)3 (M = Mn, Cd; X = Cl, I; CuIM-MFU-4l), was synthesized through post-synthetic modification of the corresponding materials M5X4(btdd)3 (M = Mn, Cd; X = CH3CO2, I; MX-MFU-4l). This strategy adjusts the H2 adsorption enthalpy at the trigonal pyramidal CuI sites as a function of the ionic radius of the central metal ion of the pentanuclear cluster node, leading to −33 kJ/mol for M = ZnII (0.74 Å), −27 kJ/mol for M = MnII (0.83 Å), and −23 kJ/mol for M = CdII (0.95 Å). Thus, CuICd-MFU-4l provides a second, more stable example of optimal H2 binding energy for ambient-temperature storage among reported metal–organic frameworks. Structural, computational, and spectroscopic studies indicate that a larger central metal planarizes trigonal CuI sites, weakening the π-backbonding to H2.
Achiral plasmonic antennas enhance differential absorption to increase preferential detection of chiral single molecules
Authors: Chattopadhyay Saaj , Biteen Julie
Published: June 2024

Plasmonic antennas increase the photon flux in their vicinity, which can lead to plasmon-enhanced fluorescence for molecules near these nanostructures. Here, we combine plasmon-coupled fluorescence and fluorescence-detected circular dichroism to build a specific and sensitive detection strategy for chiral single molecules. Electromagnetic simulations indicate that a two-dimensional gold nanoparticle dimer antenna enhances the electric field and optical chirality of a plane wave in its near field. Furthermore, this optical chirality enhancement can be tuned based on the polarization of the incident electric field, such that enhancing the optical chirality via these antennas will increase the differential absorption of parity-inverted fields. We measured the fluorescence from single molecules of chiral absorbers—Cy5 J-dimers assembled in double-stranded DNA backbones—and achieved increased detectability of these right-handed molecules near achiral Au NP dimer antennas under right circularly polarized illumination. This strategy offers a new approach to distinguishing weakly fluorescent enantiomers.

Spatial genetic structure of Ficus superba (Moraceae) in mainland and insular Singapore
Authors: Yeo C.K. , Tan H.T.W.
Published: June 2024

Monoecious Ficus L. (Moraceae) species have putatively effective long-distance pollen dispersal and low population densities. The lack of spatially defined populations and the assumption of high gene flow led to the dearth of work on the Spatial Genetic Structure (SGS) of monoecious species. Furthermore, as only forest or inland species were studied, the effects of landscape heterogeneity and discontinuous habitats have been overlooked. To address this, Ficus superba (Miq.) Miq., a monoecious spatially aggregated coastal and insular species from Singapore, was studied to ascertain if population homogenisation could result from pollen flow even when the assumptions of spatial and landscape homogeneity were violated. Individuals were genotyped using dominant Amplified Fragment Length Polymorphism (AFLP) markers. Bayesian clustering software and Principal Component Analysis (PCA) were used to test for population genetic structure. SGS analyses and Mantel’s Tests were performed to test for the presence of significant fine-scale SGS and Isolation By Distance (IBD). Significant population genetic structure and SGS were found, with one mainland population more differentiated from the remaining insular and mainland populations. It is hypothesised that the spatial aggregation and landscape heterogeneity significantly distort gene flow through aggregated seed dispersal and greater impedance to pollen flow over land than sea. This calls into question the supposed dichotomy in gene flow characteristics of monoecious versus dioecious figs attributed to pollinator behaviour.

We collected specimens in Ilocos Norte, Philippines, and identified them as Plagiostachys parviflora (C.Presl) Ridl. (Zingiberaceae: Alpinioideae), a species of which the identity remains doubtful since its publication in 1827. This is one of the ginger species described and illustrated by Carl Presl using Thaddäus Haenke’s specimen collected in the Philippines during the Malaspina expedition. The description of Plagiostachys parviflora is expanded here based on new collections including pickled fertile material, and the species is illustrated by a colour plate. Notes on its distribution, phenology, local names, and other notes are also given. Amomum parviflorum C.Presl var. bifidum C.Presl and Plagiostachys rolfei (K.Schum.) Ridl. are treated here as synonyms of P. parviflora. Lectotypes are designated for Amomum parviflorum, Amomum parviflorum var. bifidum, and Alpinia rolfei K.Schum., and their respective type localities are discussed. Plagiostachys parviflora matched the criteria of the IUCN Red List to be considered as Vulnerable (VU). An updated key to the Philippine species of Plagiostachys is also provided.

The method for calculating phase angle between exciter force of vibration exciter and roller displacement
Authors: Shishkin E. A.
Published: June 2024

Introduction. In the process of soil compaction it is important to have information about the current density of the layer, as it enables to quickly adjust the load on the compacted material. The field methods of compaction quality assessment do not cope with this task, as they make point estimation within the pavement area. Therefore, continuous compaction monitoring systems installed on vibratory road rollers are becoming increasingly common. The systems developed by BOMAG and AMMANN require, among other things, the phase angle between the exciter force and the roller movement to calculate the compaction quality index. The phase angle is determined by the unbalance position sensor, which is very labor-intensive. In addition, continuous compaction monitoring systems include an accelerometer. The purpose of this paper is to develop an indirect method for calculating the phase angle from accelerometer readings.

The method of research. In order to achieve the purpose of the work, a roller-soil single-mass model in a typical mode for vibratory rollers (periodic loss of contact) has been studied. As a result of modeling it has been found that the reaction of the compacted material has the main influence on the vertical component of a roller acceleration and practically does not affect the horizontal component. This is confirmed by the experimental data.

Results. The phase angle can be determined by mutual correlation of the horizontal and vertical acceleration signals of the roller obtained with the accelerometer.

Conclusion. The study proposes a new method of calculating the phase angle between the exciter force and the roller displacement, which eliminates the direct measurement of this angle. The calculation of the angle is based on the readings of a two-axis accelerometer installed on the road roller. The proposed method enables to simplify the system of continuous compaction control and reduce the labor intensity of phase angle measurement.
Technology of regular urban passenger transportation operation improvement
Authors: Azemsha S. A.
Published: June 2024

Introduction. The degree of passenger vehicle capacity utilisation affects the economic component of regular urban passenger transport operation, as it depends on the number of passengers transported, which affects the revenue from transportation, as well as on the passenger vehicle capacity, which affects the cost of transportation. One of the tasks formulated in the programme-target documents of the Republic of Belarus is to achieve full selfsufficiency of urban regular passenger transport. One of the ways to ensure this can be maximising the degree of capacity utilisation set by the manufacturer of the passenger vehicle.

The aim of the paper is to estimate the degree of passenger vehicle capacity utilisation and dynamics of its change, as well as to develop measures to improve the efficiency of urban regular passenger transport.

Materials and methods. When writing the article, the data obtained by a full-scale survey of passenger flows in one of the cities of the Republic of Belarus, conducted in 2019 and in 2024, were used. When writing the article, statistical methods (descriptive statistics, fitting, visualisation, assessment of significance of differences using statistical criteria), analysis of scientific literature and work technology, synthesis of proposals were used.

Conclusions. The low degree of utilisation of passenger vehicle capacity is shown. The new technology of the organisation of work of the city passenger transport of regular communication, allowing to increase use of capacity of passenger vehicles and, at the expense of this efficiency of such work is offered.

The possibility of further use of the results of scientific work. The received results substantiate necessity of development of scientific toolkit for optimisation of assignment of passenger vehicles to flights taking into account passenger load on them and other restrictions.

Practical significance. This article shows the need to develop measures to improve the efficiency of passenger vehicle capacity utilisation for the purposes of increasing the efficiency of urban regular passenger transport.

Originality. This paper shows the change in the degree of use of passenger vehicle capacity, shows the factors affecting it, and proposes a new technology for organising the work of urban regular passenger transport. The article will be useful for officials of the management bodies responsible for the organisation of the work of urban passenger transport of regular communication, as well as employees of the enterprises of urban passenger transport, transport scientists.
Redistribution of efforts between the belts of four-belt towers
Authors: Krasnoshchekov Yu. V. , Zapoleva M. Y.
Published: June 2024

Introduction. The article presents the results of a study of the calculation features of four-belt towers depending on the direction of a wind action. The purpose of the article is to identify the conditions for the redistribution of forces in the belts of a grid tower under the action of a wind load along a diagonal of a square section and loss of stability of the most compressed belt. The attention is drawn to the fact that with the development of the process of loss of stability of the compressed belt, it does not turn off completely, but continues to partially carry the load. The data obtained indicate that it is possible to calculate all the elements and the tower as a whole according to a single scheme A (a wind pressure on the face of the tower), taking into account the coefficient of the wind angle. In the calculation example, graphical dependences of the forces in the belts on the resistance are obtained.

Materials and methods. A feature of the calculation of four-belt towers is the dependence of the forces in the belts on the direction of the wind load. According to the maximum compression forces under the action of wind on the rib and bending of the tower, the cross section and length of the panel of all belts are assumed. The resulting reserve of strength and rigidity of the tower of the two belts in the limiting state adopted in the design standards is not possible to implement, since the limiting state of the compressed belts is assumed by the condition of stability in the form of bifurcation. If the limiting state of the belt panels is assumed according to the condition of bearing capacity in the supercritical stage of deformation, then it is possible to calculate the redistribution of compressible forces to reserve belts. In the given example, the criterion of resistance is used to analyze the redistribution of forces between the belts when the stability of the most compressed belt is lost according to the design scheme B (wind pressure on the tower rib).

Conclusions. The results of modelling the tower calculation in the LIRA PC showed that taking into account the supercritical deformation of the compressed belt in the elastic stage makes it possible to calculate all the elements and the tower as a whole according to a single scheme A (a wind pressure on the face of the tower), taking into account the coefficient of the wind angle. At the same time, even with an increase in the coefficient value to 1.4 (instead of 1.2), the calculation efficiency is greater than the traditional one. The results of the study may be the basis for reducing the estimated length of the elements of the most compressed belt according to the calculated scheme B.

Mobility of physically disabled persons is a concerning social issue nowadays. The basic Tricycle is a three-wheeled design, pedaled by disabled persons in the side and seat in the middle for sitting arrangement. They use only one hand to steer the handle because other-hand is used to rotate the pedal. Our aim is to design a low-cost tricycle that will allow person to accelerate and steer the tricycle from a single place. The way the Bike Chair works is the back is essentially a regular bicycle, but the front turns it into a tricycle, and sort-of makes it a wheelchair and bicycle combo. The disabled passenger sits on the front two wheels, as the driver uses their front wheels to steer the bike. The passenger has buckles and strap to secure the min place and top even them from falling out of the chair during the bike-ride. Furthermore, the tricycle's compact size, maneuverability, and zero emissions make it an attractive option for reducing traffic congestion and pollution in densely populated urban areas. Future research directions include optimization of battery and motor technologies for enhanced performance and efficiency, as well as integration of smart features for improved user experience and safety.

The ability of a person to plan, monitor, assess, and modify their own behavioural patterns in order to more skillfully address challenges is known as metacognition. Although it is only described as "thinking about thinking," active thought monitoring and modification make it much more than that. The ability to think critically, solve problems, and be self- aware are all prerequisites for this type of self-regulation. When it came to meaningful learning, most students mainly relied on rote learning. Despite the significance of metacognitive thinking skills in the process of learning, the acquisition of these abilities is not widely emphasized in classrooms today. The majority of instructors place a lot of emphasis on the subject matter while paying little consideration to how their students are absorbing it. Pupils who possess Metacognitive Skills are able to identify their own cognitive capacities, take charge of their education, evaluate their own progress, understand the reasons behind their achievements and shortcomings, and pick up new techniques. Therefore, it is essential for the teacher to assist the student in growing their Metacognitive abilities. The practice of metacognitive skills in the classroom makes them autonomous learners. The students by learning this skills are able to monitor their own Knowledge, evaluate themselves and are able to take independent decision in the future life. Metacognitive Skills helps the students to develop self efficacy which in turn help the students to excel in their academic achievement.
Exploring Experiences of Mental Health and Wellbeing-Related Tattoos in Aotearoa
Authors:   , Tottle Caitlin
Published: June 2024

People may obtain a tattoo for a range of reasons; for example, some tattoos may be directly relevant to a person’s mental health and/or wellbeing. This research explored how individuals in Aotearoa experience their mental health and wellbeing-related tattoos or moko. Specifically, I was interested in the perceptions of how/if tattoos influenced their mental health and wellbeing. Tattoo research in the field of mental health and wellbeing is still in its infancy, but shows promising evidence around the potential therapeutic value of tattoos. I took a qualitative approach to analysing interviews with 13 participants. I conducted and transcribed one-on-one semi-structured interviews, and analysed these using reflexive thematic analysis. I identified five themes: Psychological Function (of tattoos), Active Reminders, Empowerment and Agency, Temporality, Communication and Connection. Participant’s experiences of memorial tattoos (tattoos symbolizing the passing of someone or something important to them) are presented as a case study to show the interconnectedness of themes.

The findings suggest that tattoos are generally perceived as positively influencing participants behavioural and emotional function, in part by aiding with emotion regulation, and enabling positive ways of coping with distress. Tattoos were also an avenue of self- expression which empowered participants, helping them feel confident in themselves and their identity. Participant’s tattoos also helped them face challenges and gave them confidence in their ability to cope with distress. Their tattoo experiences appeared to share similarities with some therapeutic practices, namely art therapy, and trauma recovery models. This study shows how tattoos can be a powerful transformative experience that positively influences mental health and wellbeing: for participants, their tattoos were more than a form of art, they are embodiments of identity and life experiences.
Risk Analysis of the Development of Sustainable Dongtan
Authors: Ji Ningbin
Published: June 2024

Dongtan is set to be developed as a sustainable urban-rural integration, aiming to attract a wide range of commercial and leisure investments. The Shanghai Industrial Investment Corporation (SIIC), the largest international investment group owned by the Shanghai municipal government, is leading the Dongtan project in partnership with Arup. The project’s risks are categorized into eight major groups: (1) Force majeure, (2) people-related risks, (3) financial and economic risks, (4) political and country risks, (5) environmental risks, (6) completion-related risks, (7) design-related risks, and (8) technology risks. Among these, political risk is particularly notable for its high probability and significant impact. Effective project risk management is essential to foresee and address uncertainties that could jeopardize the project's objectives and timelines. Appropriate strategies must be implemented to manage and mitigate these risks.
Preparation and Performance Study of Cementitious Capillary Crystalline Waterproof Materials
Authors: Li Hui , Liu Yu , Zhang Gaoshang
Published: June 2024

Cementitious capillary crystalline waterproof materials (CCCW for short) offer durability and excellent waterproofing properties, making them a popular option for building waterproofing. Some scholars have studied the proportioning of such materials. However, these studies lack the relationship between the impermeability pressure of mortar and the components, and the mechanism of action is somewhat debatable. Therefore, we adopted a two-step method in our experiments. Firstly, we screened out the components that significantly impact impermeability from a variety of active components by orthogonal test. We then optimized the design of the active group ratio using the simplex lattice method. Lastly, we conducted a performance test of the optimal ratio and explored the waterproofing mechanism of homemade CCCW.

Vamos mostrar as principais ideias contidas na obra do autor, através de sua leitura, e buscar ao final uma formulação de um pensamento hermenêutico crítico constante na obra. Não se trata de dar novos fundamentos, conceitos ou elucidações contidas na obra, mas puramente analisar o que propunha o autor.
REPETIR SEM ELABORAR
Authors: Rodrigues Leonardo
Published: June 2024

O texto visa apresentar a querela entre Sigmund Freud e Gilles Deleuze acerca da noção de “repetição” – noção fundamental tanto para a metapsicologia do primeiro, quanto para a filosofia do segundo. Através da crítica de Deleuze ao caráter eminentemente negativo e “derivativo” da repetição em Freud (ideia que, no caso de Freud, aparece sobretudo em dois textos fundamentais: “Recordar, repetir e elaborar”, de 1914, e “Além do princípio do prazer”, de 1920), será refeito o itinerário das “sínteses do tempo”, presentes na obra Diferença e repetição, apontando para uma noção positiva de repetição – sem, contudo, incorrer às figuras do Mesmo e ao primado da representação. Uma “repetição complexa”, que se faz acompanhar de uma “diferença pura”, cuja temporalidade mais adequada é aquela própria à lógica da multiplicidade, isto é, um tempo “não-reconciliado”, parafraseando a expressão de Peter Pál Pelbart.
