Borazine and its derivatives can be considered critical doping units for engineering hybrid C(sp2)-based molecules with tailored optoelectronic properties. Herein, we report the first synthesis of hexaarylborazines that, bearing ortho-substituted aryl moieties, extend threedimensionally. Using a one-pot protocol, we first form an electrophilic chloroborazole and then react it with an aryl lithium (ArLi). By selecting the appropriate ortho-substituent, we can guide the ArLi to add to the BN-core in a specific way, ultimately controlling the stereochemical outcome of the three-substitution reaction. Rationalization of the stereochemical model through computational analysis allowed us to show that when aryl lithium nucleophiles bearing rigid long-range ortho-substituents are used, i.e., stiff substituents. The ortho-substituent shields its side of the electrophilic B3N3 core, biasing the incoming ArLi to add anti at each addition step, forming the final tri-aryl borazine exclusively as cc-isomer. Leveraging this stereoselective approach, prototypical multichromophoric borazine derivatives were prepared, and we showcased how the stereochemical arrangement of these chromophores distinctly influences their redox behavior. This methodology paves the way for previously inaccessible borazines to serve as privileged precursors to transcend the conventional bidimensionality associated with graphenoid systems and pioneer the construction of new forms of three-dimensional C(sp2)-based architectures.
New states of water and the emerging field of constrained physics
Authors: Miao Zhongzheng
Published: September 2024

Have new states of water been discovered? Utilizing molecular dynamics and first-principles analyses across thousands of models, this paper introduces a dual-limit temperature regulation method under mass and spatial constraints, yielding water molecular chains and 2D water films, uncovering the key to unlocking a new world of water states. This has led to the emergence of dazzling and magical water structures, accompanied by the continuous emergence and summarization of corresponding electrical, optical, thermal, and mechanical laws as new structures appear. Concepts such as "new states of water", "water molecular chains", "spiral ionic networks", "universal dual-limit temperature control method" and "confined physics" are proposed. These insights delve deep into fundamental science, enhancing our understanding of water and exploring its unprecedented states. Furthermore, they extend to charged ions and polar molecules, pioneering new avenues in materials science, nanotechnology, atomic engineering, and energy conversion, with the potential to propel multiple disciplines and shape society.

Pathogenic variants in the Leucine-rich repeat kinase 2 (LRRK2) gene are a primary monogenic cause of Parkinson’s disease (PD). However, the likelihood of developing PD with inherited LRRK2 pathogenic variants differs (a phenomenon known as “reduced penetrance”), with factors including age and geographic region, highlighting a potential role for lifestyle and environmental factors in disease onset. To investigate this, household dust samples from four different groups of individuals were analyzed using metabolomics/exposomics and metagenomics approaches: PD+/LRRK2+ (PD patients with pathogenic LRRK2 variants; n=11), PD-/LRRK2+ (individuals with pathogenic LRRK2 variants but without PD diagnosis; n=8), iPD (PD of unknown cause; n=11), and a matched, healthy control group (n=11). The dust was complemented with metabolomics and lipidomics of matched serum samples, where available. A total of 1,003 chemicals and 163 metagenomic operational taxonomic units (mOTUs) were identified in the dust samples, of which ninety chemicals and ten mOTUs were statistically significant. Reduced levels of 2-benzothiazolesulfonic acid (BThSO3) were found in the PD-/LRRK2+ group compared to the PD+/LRRK2+. A negative and statistically significant association was observed between BThSO3 and Pseudomonas spp. (detected via metagenomics), which are known for degrading benzothiazoles. Among the significant chemicals tentatively identified in dust, two are hazardous chemical replacements: Bisphenol S (BPS), and perfluorobutane sulfonic acid (PFBuS). Furthermore, various lipids were found altered in serum including different lysophosphatidylethanolamines (LPEs), and lysophosphatidylcholines (LPCs), some with higher levels in the PD+/LRRK2+ group compared to the control group. A cellular study on isogenic neurons generated from a PD+/LRRK2+ patient demonstrated that BPS negatively impacts mitochondrial function, which is implicated in PD pathogenesis. This pilot study demonstrates how non-target metabolomics/exposomics analysis of indoor dust samples complemented with metagenomics can prioritize relevant chemicals that may be potential modifiers of LRRK2 penetrance.
External Photosensitizer Free Function-Integrated Cu(II)-Complex Catalyzed Photo Driven CO2 Reduction

Published: September 2024

Developing a function-integrated catalyst from earth-abundant elements, capable of efficient light harvesting and electron transfer, is crucial for enhancing the efficacy of CO2 transformation, a critical step in environmental cleanup and advancing clean energy prospects. Traditional approaches relying on external photosensitizers, comprising of 4d/5d metal complexes, often face challenges in intermolecular electron transfer, and attachment of photosensitizing arms to the catalyst increases dependency on intramolecular electron transfer kinetics, underscoring the need for a more integrated solution. We report a new Cu(II) complex, K[CuNDPA] (1[K(18-crown-6)]), bearing a dipyrrin amide-based trianionic tetradentate ligand, NDPA (H3L), which is capable of harnessing light energy, despite having a paramagnetic Cu(II) center, without any external photosensitizer and photocatalytically reducing CO2 to CO in acetonitrile: water (19:1 v/v) with a TON as high as 1132, a TOF of 566 h-1 and a selectivity of 99%. This complex also shows hemilability in the presence of water, which not only plays a role in a proton relay mechanism but also helps stabilize a crucial Cu(I)-NDPA intermediate. The hemilability was justified by the formation of N3O (2) and N2O2 (3) coordinated congeners of the N4 bound complex 1. The overall mechanism was further investigated via spectroscopic techniques like EPR, UV-vis, and Spectroelectrochemistry, culminating in the justification of a single electron-reduced Cu(I)NDPA species as a proposed intermediate. In the next step, the binding of CO2 to Cu(I) complex and subsequent electron transfer to form Cu(II)-CO2•‾ was indirectly probed by a radical trapping experiment via the addition of p-methoxy-2,6-ditertbutylphenol that led to the formation of a phenoxyl radical. This work opens new strategies for designing earth-abundant robust molecular catalysts that can function as photocatalysts without the aid of any external photosensitizers.

Authors: Newman Luke , Patton Mackenzie , Rodriguez Breyanna , Sumner Ethan , Vaissier Welborn Valerie
Published: September 2024

Polarizable force fields crucially enhance the modeling of macromolecules in polar media. Here, we present new parameters to model six common monosaccharides with the polarizable AMOEBA force field. These parameters yield a thinner, but denser, hydration layer than that previously reported. This denser hydration layer results in eliminating non- physical aggregation of glucose in water – an issue that has plagued molecular dynamics simulations of carbohydrates for decades.

Published: September 2024

Acute lymphoblastic leukemia is a very important cancer in childhood but quite prominent in later years of life for the genetic defects in lymphoid progenitors, which are hallmarks of the disease. In children, ALL mostly affects those aged between 2 and 6 years old and, against the background of contemporary biology knowledge and treatment approaches, is associated with more than 80% cure rates. However, approximately 20% of children with ALL relapse; therefore, there is a huge need for better risk identification and treatment optimization. In adults, ALL mainly affects B-cell precursors and is treated with chemotherapy and, in some cases, stem cell transplantation. An accurate and early diagnosis of ALL is of key importance but difficult to realize due to morphological similarities between normal cells and leukemic cells. This study, therefore, proposes a CNN model to improve diagnostic accuracy. Furthermore, it exploits the capabilities of CNN in feature extraction with Adamax Optimizer and the Categorical Cross-Entropy Loss Function to deal with imbalances and noise in the dataset. RESNET50-CNN has achieved 98.63% accuracy in classification and is hence a very strong tool in ALL detection and classification.

Published: September 2024

Obesity has become a global public health issue due to its rapidly increasing prevalence.
Sea grapes powder drink (SPD) as a functional food has the potential to become an
important biomarker in the improvement of obesity. The biomarkers in obesity can be
assessed by Lee’s index and lipid profile. Due to its high antioxidant content, SPD can
improve both Lee’s index and lipid profile. The objective of this study was to analyse the
effect of SPD on the obesity biomarkers of Wistar rats. In this research, a completely
randomized design that involved 24 male rats weighing between 150–250 g was used.
Rats were randomly put into six groups. Biomarkers were measured using Lee’s index,
lipid profile and the weight ratio of both visceral fat and liver. Results after 21 days of
intervention showed a reduction in Lee’s index in the group that was given HFD + SPD 1
g, 1.5 g and 2 g. The visceral fat weight ratio in HFD + SPD 1.5 g and 2 g group
significantly decreased. However, it had no effect on the liver weight ratio. Levels of
Total Cholesterol (TC), Triglyceride (TG), and Cholesterol-Low Density Lipoprotein (CLDL) in the HFD + SPD 1 g, 1.5 g and 2 g group significantly decreased. The Cholesterol
-High Density Lipoprotein (C-HDL) dramatically increased HFD + SPD 2 g group. SPD
is effective in improving Lee's index, visceral fat weight ratio and lipid profile but not
liver weight ratio. SPD can be used as an alternative therapeutic product in the
management of obesity and consequent reduction of its prevalence.
Constitutional by Nature: The Accountability Function of the New Zealand Parliamentary Press Gallery
Authors:   , Peoples Thomas
Published: September 2024

The New Zealand Parliamentary Press Gallery fulfil a vital accountability function within New Zealand’s democracy. This appears to be constitutional in nature. Despite the importance of its role, there has been little scholarship which seeks to understand the form and function of the Press Gallery, particularly in an accountability context. In this dissertation I seek to build a foundational understanding of the accountability function of the Parliamentary Press Gallery. In doing so I consider The Gallery's foundation, form and function and explore how these interact to facilitate one of more important, yet unknown, accountability fora within New Zealand's democracy. This papers analysis serves as a valuable foundation for understanding the Press Gallery in accountability terms. It highlighted a range of shortcomings in The Gallery's function, as well as the unusual fit of The Gallery in comparison to other, similar, accountability bodies within New Zealand's constitutional arrangements. It also indicates that the form and function of the Press Gallery is constitutional by nature.

Published: September 2024

Individual presentation is one of common presentations used by students to present certain topic given by the lecturers in the class. This kind of presentation may take place in a range of setting such as in the classroom by providing question-and-answer session. Individual presentation might also invite classroom interaction among the students. One specific aspect of individual presentation which may contribute to the effective classroom interaction is the use of discourse markers by the students. This paper focuses to investigate the functions of discourse markers used by the students in the individual presentation as well as the students’ interaction during the presentation. Using data from an English class, this study describes the occurrences of discourse markers (DMs) used by the students in their individual presentations. To collect data, the researchers recorded individual presentations of the students in the class. Two long recording and transcription of the individual presentations was sampled and analyzed using discourse analysis approach. The discourse markers used by the students were analyzed using Schiffrin’s perspective of discourse markers (1987). Findings show that the students’ most common use of discourse markers function as pause filler, delaying tactic, hesitation device, to order the sequence of what the speaker says. Findings of this study are relevant to improve students’ English language proficiency and serves as a beneficial input for teachers and students to create effective classroom interaction.Keywords: Individual Presentation, Discourse Markers, Discourse Analysis, Scriffin’s discourse makers (DMs) perspective

Published: September 2024

The goal of the study was to identify the best strategy to utilize and how effectively students could translate abstract journals. Students from Universitas Negeri Makassar studying English education participated in this descriptive quantitative study. There were 10 students in total that made up the study's subject. the information gathered by text analysis. The findings indicated that students' translations of abstract Journal were "Excellent" in accuracy, with a degree of mastery between 80 to 100%. It implies that a small amount of correction is still required. There, a total of nine students made progress toward a good level, while one student demonstrated excellent mastery. Additionally, literal translation and semantic translation were the two most often employed translation techniques. The researcher proposes that the teacher should focus more on the issues of the students in light of this research. Students should practice translating texts on their own more often, be guided in their efforts, and motivated to do so. They should also learn more grammar rules, expand their vocabulary by memorizing more words, and refrain from using Google Translate too frequently.Keywords: translation, accuracy, translation method

Nodecness of Soft Generalized Topological Spaces
Authors: Alqahtani Mesfer H. , Alghamdi Ohud F. , Ameen Zanyar A.
Published: September 2024

In this work, we define a new class of soft generalized topological spaces, namely strongly soft nodec, with the use of strongly soft nowhere dense sets. Then, we study the basic properties of these spaces and show that if the product of two soft generalized topological spaces is a strongly soft nodec space, then each one is a strongly soft nodec space. Then, we extend these notions to T0-strongly soft nodec generalized topological spaces by using the soft quotient functions and discussing their main properties. We also show the inverse of a surjective soft quotient function preserves the soft closure and soft interior of a soft subset of a codomain soft set in soft generalized topological space. Further, we use soft quasi-homeomorphism and soft quotient functions to make comparisons and connections between these spaces with the support of appropriate counterexamples. Then, we successfully determine a condition under which the soft generalized topological space is a soft weak Baire space and hence a strongly soft second category.
