Strategies for Non-Covalent Attachment of Antibodies to PEGylated Nanoparticles for Targeted Drug Delivery.

Polyethylene glycol (PEG)-modified nanoparticles (NPs) often struggle with reduced effectiveness against metastasis and liquid tumors due to limited tumor cell uptake and therapeutic efficacy. To address this, actively targeted liposomes with enhanced tumor selectivity and internalization are being developed to improve uptake and treatment outcomes. Using bi-functional proteins to functionalize PEGylated NPs and enhance targeted drug delivery through non-covalent attachment methods has emerged as a promising approach. Among these, the one-step and two-step targeting strategies stand out for their simplicity, efficiency, and versatility. The one-step strategy integrates streptavidin-tagged antibodies or bispecific antibodies (bsAbs: PEG/DIG × marker) directly into PEGylated NPs. This method uses the natural interactions between antibodies and PEG for stable, specific binding, allowing the modification of biotin/Fc-binding molecules like protein A, G, or anti-Fc peptide. Simply mixing bsAbs with PEGylated NPs improves tumor targeting and internalization. The two-step strategy involves first accumulating bsAbs (PEG/biotin × tumor marker) on the tumor cell surface, triggering an initial attack via antibody-dependent and complement-dependent cytotoxicity. These bsAbs then capture PEGylated NPs, initiating a second wave of internalization and cytotoxicity. Both strategies aim to enhance the targeting capabilities of PEGylated NPs by enabling specific recognition and binding to disease-specific markers or receptors. This review provides potential pathways for accelerating clinical translation in the development of targeted nanomedicine.

The Role of the Nitro Group on the Formation of Intramolecular Hydrogen Bond in the Methyl Esters of 1-Vinyl-Nitro-Pyrazolecarboxylic Acids

All reactions involving the nitrogen atom in 3(5)-substituted pyrazoles inevitably lead to a mixture of N-substituted 3- and 5- isomers due to tautomerism. The position of substituent can affect the behavior of N-vinyl isomers, in particular, the ability of some functional groups to form =C-H...O or =C-H...N weak hydrogen bonding type interaction with α-hydrogen of vinyl group due to steric reasons. Moreover, the additional substituents in the pyrazole ring can further influence the possibility and nature of specific intramolecular interactions. Here we have shown the effect of the nitro group on the formation of hydrogen bonds in methyl esters of 1-vinyl-4-nitro-3(5)- and 1-vinyl-5-nitro-3(5)-pyrazole carboxylic acids. A comprehensive study, including synthesis, quantum chemical calculations, NMR and XRD analysis, allowed to conclude that, contrary to expected, in the methyl ester of 1-vinyl-4-nitro-5-pyrazolecarboxylic acid, the formation of a planar conformation is unfavorable, preventing formation of a classical hydrogen bond. On the other hand, there is a hydrogen bond between the nitro group and vinyl group in 1-vinyl-5-nitro-pyrazolecarboxylic acids.

Finely tuned energy gaps in host-guest complexes: Insights from belt[14]pyridine and fullerene-based nano-Saturn systems

Over the past few decades, doping, physisorption and chemisorption remained some of the commonly utilized methods to modify the energy gaps and electronic properties of materials. Yet, achieving precise control over tuning the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) levels within these systems persisted as a remarkable challenge. Therefore, there is a growing need for systems that facilitate exact adjustments of energy gaps and HOMO/LUMO levels. Here, in this research work, the nano-Saturn host-guest complex systems are designed based on belt[14]pyridine as a host and fullerene nanocages (C20, C32, C34 and C36) as guests. The greater thermodynamic stability of the complexes is revealed by the higher values of interaction energies (Eint) for these complexes, ranging from −45.50 to −56.81 kcal/mol. The frontier molecular orbital (FMO) analysis revealed the contribution of HOMO of fullerenes and LUMO of belt[14]pyridine towards the HOMO and LUMO of the designed complexes, respectively. The energy gaps of the complexes also decrease compared to the constituents, with the least Egap of 0.52 eV observed for C20@N-belt. Moreover, the charge transfer from the host towards the guests is predicted and confirmed via natural bond orbital (NBO) and electron density difference (EDD) analyses. The non-covalent interaction index (NCI) and quantum theory of atoms in molecules (QTAIM) analyses determine the nature and strength of interactions in the host-guest complexes. Moreover, it is noticed through the UV–vis analysis that the bare fullerenes show the maximum absorption in ultraviolet (UV) region, but after complexation, maximum absorption is observed in visible and near infrared (NIR) regions, with highest λmax of 927 nm for C36@N-belt. These findings highlight the successful development of nano-Saturn host-guest complexes with precise control over HOMO-LUMO levels and energy gaps. This work aims to address the challenges in fine-tuning the electronic properties and demonstrates potential applications in optoelectronics, photovoltaics, and NIR-based sensors. Moreover, the ability to tune the electronic properties can guide future material design strategies for advanced energy storage and photonic devices.

Beyond Index Conditions: Applying a Multimorbidity Approach to Renal Cancer Nursing

ObjectiveThis article aims to describe the key components of renal cancer nursing and multimorbidity nursing, and reflects on how adopting a multimorbidity approach to renal cancer nursing can help nurses provide holistic patient care. MethodsThis is a discussion paper drawing on relevant evidence and theory. ResultsRenal cancer nurses have a highly specialised knowledge base and are able to use this expertise to deliver excellent care to people with cancer. However, lots of people with cancer have other conditions as well. Adopting a multimorbidity approach to nursing care provides a more holistic framework for care delivery. ConclusionsCancer nurses are ideally placed to support patients in this way, so they are able to deliver care which accounts for factors such as treatment burden and how this impacts on patients and carers. Implications for nursing practiceNurses who care for people with renal cancer should view their patients through the lens of multimorbidity. This involves screening for other chronic conditions, considering polypharmacy, providing emotional support and continuity of care, and coordinating care in a way that accounts for the potentially burdensome nature of the patient's interactions with health care.

Webtoons, Desperately Seeking Viewers: Interactive Creativity in Social Media Platforms and Cultural Appropriation of Global Media Production

Webtoons optimize interactivity and participation of media users in the world of digital media by consolidating a unique digital culture. This article examines the role of users in interactive media by exploring the case of webtoons in the context of a changing global political economy and cultural dominance. Korean platform monopolies have established a new business model for webtoons and developed it as a center of Korean creative power. While webtoons have increasingly expanded and attracted the global market and the global audience, some persistent social issues remain, including the precarious labor structure, monopolistic power in the industry, and ideological dominance in content. Although webtoon viewers are often recognized as cultural intermediaries and powerful agents for their contributions to interactive creativity, their role has fluctuated according to changing political-economic structures and industrial strategies. In the course of expanding to the global market and to new business areas such as intellectual property (IP), webtoons have evolved in new fashions while disclosing the ambivalent nature of participatory media and digital interactivity. This article elucidates the double faces of interactive creativity focusing on viewers’ participation in webtoon production in the context of changing webtoon industry and growing partnership with global media.

Adsorption Effects of Isoniazid Drug Over Carbon Nanotube (C56H16) and Ab‐Initio Molecular Dynamics Simulation (ADMP) – A Computational Quantum Chemical Approach

AbstractTuberculosis (TB) is a deadly disease of global concern. The previous work studies the geometric optimization, vibrational analysis, TDDFT, and electronic properties of the TB pathogen drug isoniazid (ISO). This communication will discuss the changes in geometry, electronic properties, and shielding parameters of ISO‐absorbed carbon nanotube (CNT) (CNT‐ISO, C56H16). This study has used the DFT/B3LYP/6–311G (d, p) method for the first time to report ISO's electronic structure and interaction parameters on the CNT surface. The same level theory is used to discuss the thermodynamic stability of CNT‐ISO. The calculated UV spectra of CNT are compared with UV spectra of CNT‐ISO by using the same level theory in a water solvent, which provides a better comprehension of CNT as a drug delivery system after absorption of the ISO in the human body. The nature and strength of interactions have been discussed with the help of NBO and AIM analysis, and the frontier orbital highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO‐LUMO) gap, chemical softness, and chemical hardness have been calculated to understand its complete chemical properties. The characters of the frontier molecular orbitals are discussed and analyzed by comparing the DOS spectra of CNT with CNT‐ISO. It has also examined the scan plot of interaction with time using ab‐initio dynamics simulation (ADMP) calculations.

Research on Mixed Reality Hand Interaction Technology in Flight Simulation Teaching

Abstract The integration of mixed reality simulation training in institutional education and teaching processes can yield significant quality benefits. Non-wearable interactive methods represent a more natural form of hand interaction within flight cockpits, covering various emerging fields such as mixed reality, computer vision, and human-computer interaction. This paper is guided by a “human-centered” approach to natural human-computer interaction and proposes a virtual hand mixed reality interaction scheme based on hand natural feature points. This study introduces a hand detection, segmentation, and recognition algorithm based on skin colour and key hand feature points. Initially, the algorithm uses the Otsu adaptive threshold algorithm in the YCbCr space for skin colour detection to accommodate varying image brightness levels. Subsequently, it employs a hand Keypoint model for rapid hand detection within skin-like areas while excluding interference from other regions. During the process of hand tracking, optimization prediction is performed using the particle filter algorithm combined with the artificial fish swarm algorithm to achieve tracking accuracy within six pixels in both horizontal and vertical directions. Gesture recognition involves extracting Fourier descriptive contour features of the hand bone structure through identification of feature points. Furthermore, this study combines the optimization capabilities of the artificial fish swarm algorithm to enhance support vector machine model parameter optimization for improved recognition rates. Testing involved 800 processed images as part of a test set for gesture recognition; only five commonly used gestures within flight cockpits were recognized and classified with an accuracy rate reaching up to 98%. Finally, this research presents virtual representations of common operational gestures including natural hand states, control stick manipulation, and throttle handling positions, button activations, and rotational movements via head-mounted displays or screens. The proposed mixed reality-based hand gesture interaction system addresses challenges related to complex background interference during hand detection in cockpit environments as well as issues arising from lighting disturbances. Additionally it resolves problems associated with insufficient particles leading to tracking failures while significantly enhancing registration effects during tracking processes. Moreover it mitigates issues related to Fourier descriptive features being influenced by background variations or changes in pose along with limitations pertaining to expressing singular forms of gestures thereby improving overall classification accuracy.

Exploring Photophysical Properties of Organic Doped Polymeric Aggregates for Detecting Relevant Inorganic Pyrophosphate: A Pathway to Sustainable Development

Pyrophosphate (PPi) is an important environmentally and biologically relevant analyte and its easy and efficient detection is crucial for sustainable development. So, here we designed and synthesized organic-doped polymeric aggregates varying the signaling units (pyrene and anthracene) and examined their photophysical properties. By altering the signaling unit while keeping the polymeric backbone intact, we observed aggregate changes and studied their optical response with inorganic pyrophosphate (PPi). Among these probes, PYR-PEI exhibited a superior turn-off response(~6.1-fold) towards PPi in aqueous media whereas the other two probes ANH-PEI and PYR-PAH showed less response. The distinct response to PPi was primarily determined by electrostatic interaction and aggregate nature. The limit of detection (LOD) for PPi using the PYR-PEI probe was found to be 4.2 ppm, which is below the maximum allowable concentration of phosphate in surface water set by the World Health Organization (WHO) at 5mg/l. The quantification limit (LOQ) for PPi sensing was observed to be 14.27 ppm. Additionally, the PYR-PEI probe showed different fluorogenic responses (ratio-metric change) in the presence of anionic surfactant sodium dodecyl sulfate (SDS), and this resultant adduct was used for the PPi detection. The formation of premicellar aggregates between them drove the difference in the fluorogenic response with PYR-PEI and surfactant. Then the PYR-PEI composite was employed to detect PPi in spiked soil solution. Finally, chemically modified paper strips were prepared for the easy, fast, and on-location detection of PPi present in real-life samples.

New approaches for screening grape seed peptides as colourimetric modulators by malvidin-3-O-glucoside stabilisation

The colour of red wine is due to the presence of anthocyanins and their derived pigments, with malvidin-3-O-glucoside being the most predominant. Due to their chemical conformation, anthocyanins are susceptible to several conditions and have limited stability. Through copigmentation processes, anthocyanins can interact non-covalently with other molecules to enhance their stability. As a natural source of proteins and peptides, grape seeds are of particular interest because they may be of significant techno-functional value in the modulation of wine quality characteristics, such as acting as copigments to enhance colour stability. The proposed methodology allowed predicting in-depth insights into the molecular-level nature of interaction between the identified peptides when complexed with malvidin 3-O-glucoside and their colour stabilising properties. Thereby, allowing a prior screening in silico to facilitate their future application in experimental assays, such as obtaining the tested peptides with the characteristics already studied by means of grape seed meal directed hydrolysis.

The Effect of Metoclopramide on the Antinociceptive, Locomotor and Neurobehavioral Effects of Metamizole in Mice

Abstract Combining analgesic medications with distinct pharmacodynamics may result in effective analgesia and reduced adverse effects by lowering dosages of one or both medications. The objective was to investigate the nature of interactions of metoclopramide and metamizole by measuring the antinociceptive and neurobehavioral effects in mice. The drugs were administered intraperitoneally (ip) in mice. The antinociceptive effect was determined by the up-and-down method. Isobolographic analysis was performed by simultaneous injection of the two drugs at ED50 ratios of 1:1 and 0.5:0.5. The treated mice were also subjected to an open-field behavioral test as well as dorsal immobility and negative geotaxis behavioral paradigms. The ED50 of metoclopramide and metamizole were 33.71 and 43 mg/kg ip, respectively. Lower ED50 was established for metoclopramide and metamizole by 48.44% and 47.49%, respectively when given at a ratio of 0.5:0.5, and by 35.81% and 29.88%, respectively at a ratio of 1:1. The combined dose of metoclopramide and metamizole (8 and 10 mg/kg, ip, respectively) significantly decreased the open field-activity test in mice. This was observed by lower number of squares crossing compared to the control. Additionally, the drug combination resulted in a substantial increase in the duration of dorsal immobility response and delayed the negative geotaxis task when compared with the control group. The results indicated that the interaction between metoclopramide and metamizole in lower dose ratio with ED50 50:50, was synergistic in producing analgesia in mice with reduced risk for adverse reaction but with decreased behavioral and motor neuronal activity.

Transformative Earth stewardship: Principles for shaping a sustainable future for nature and society

AbstractEarth stewardship is the proactive shaping of pathways of social‐ecological change to enable people and nature to thrive. Its strategy is to identify and shape sustainable pathways of human–nature interaction. I describe three Earth stewardship approaches to addressing global changes. Two of these (resisting unfavorable change; accepting and adapting to change) are well‐accepted approaches to conservation and sustainability. The third (transformative Earth stewardship to escape unsustainable traps) is more challenging but can sometimes overcome seemingly insurmountable barriers. It can be triggered by a change in vision for society, changes in feedbacks such as social norms and incentives, or engagement of influential actors or institutions. The innovation necessary to trigger profound transformation often requires transdisciplinary perspectives that draw on multiple knowledge systems, modes of communication, and sectors of society.

Improving working memory by electrical stimulation and cross-frequency coupling

Working memory (WM) is essential for the temporary storage and processing of information required for complex cognitive tasks and relies on neuronal theta and gamma oscillations. Given the limited capacity of WM, researchers have investigated various methods to improve it, including transcranial alternating current stimulation (tACS), which modulates brain activity at specific frequencies. One particularly promising approach is theta-gamma peak-coupled-tACS (TGCp-tACS), which simulates the natural interaction between theta and gamma oscillations that occurs during cognitive control in the brain. The aim of this study was to improve WM in healthy young adults with TGCp-tACS, focusing on both behavioral and neurophysiological outcomes. Thirty-one participants completed five WM tasks under both sham and verum stimulation conditions. Electroencephalography (EEG) recordings before and after stimulation showed that TGCp-tACS increased power spectral density (PSD) in the high-gamma region at the stimulation site, while PSD decreased in the theta and delta regions throughout the cortex. From a behavioral perspective, although no significant changes were observed in most tasks, there was a significant improvement in accuracy in the 14-item Sternberg task, indicating an improvement in phonological WM. In conclusion, TGCp-tACS has the potential to promote and improve the phonological component of WM. To fully realize the cognitive benefits, further research is needed to refine the stimulation parameters and account for individual differences, such as baseline cognitive status and hormonal factors.

This study concluded that the teaching aids in the form of hydraulic bridges that had been developed proved feasible and effective and were able to improve students’ laboratory skills. The implications of this research extend to curriculum improvement and advocating for the integration of practical teaching aids, such as hydraulic bridges, to optimize student learning outcomes. Future directions include improving the implementation of hydraulic bridges across engineering disciplines and conducting longitudinal studies to assess its long-term impact on student’s academic and professional development.

A Survey on Reinforcement Learning for Recommender Systems.

Recommender systems have been widely applied in different real-life scenarios to help us find useful information. In particular, reinforcement learning (RL)-based recommender systems have become an emerging research topic in recent years, owing to the interactive nature and autonomous learning ability. Empirical results show that RL-based recommendation methods often surpass supervised learning methods. Nevertheless, there are various challenges in applying RL in recommender systems. To understand the challenges and relevant solutions, there should be a reference for researchers and practitioners working on RL-based recommender systems. To this end, we first provide a thorough overview, comparisons, and summarization of RL approaches applied in four typical recommendation scenarios, including interactive recommendation, conversational recommendation, sequential recommendation, and explainable recommendation. Furthermore, we systematically analyze the challenges and relevant solutions on the basis of existing literature. Finally, under discussion for open issues of RL and its limitations of recommender systems, we highlight some potential research directions in this field.

John Williams to Non-Williams

John Williams may have dominion over the Star Wars film scores with eighteen hours of music across nine films, but the mantle of responsibility for the Star Wars musical canon en masse has been undertaken by scores of many different composers, especially video game composers. Scholars of John Williams’s music such as Frank Lehman have analyzed Williams’s nine film scores, but there has been little research into the more than 100 Star Wars video game scores, which raises the question: how has Star Wars music developed without the guidance of its progenitor John Williams? Frank Lehman’s “Complete Catalogue of the Themes of Star Wars: A Guide to John Williams’s Musical Universe”1 cataloged the themes, motifs, source music, and thematic relationships of the nine films and proved musicologically insightful as well as incredibly useful when one seeks an understanding of the intricacies of Williams’s Star Wars film scores. Lehman’s research provides an ideal foundation for the ludomusicological inquisition of the hundred plus Star Wars game scores. The interactive nature of gaming mandates that the scores take player input into consideration leading to many unique methods of musical deployment that have changed from game to game. This research preludes the creation of a Star Wars sound and music anthology, similar to the Norton Anthology of Western Music, where ludomusicality found within scores from video games in the Star Wars universe are analyzed, cataloged, and explored. Each game/series would get its own unique catalog within the greater anthology consisting of a collection of analyses of the motifs, themes, and anything else of particular ludomusical interest. This poster presents a preliminary analysis of the deployment of motifs in the video games Star Wars Chess (1993) and Star Wars: X-Wing (1993), the first steps taken toward cataloging these video game scores. This proposed catalog will include analyses of ludomusicality within the Star Wars video game scores, showing how the player and computer interact to customize the listening experience of original and borrowed themes from the Star Wars movies. Combining Lehman’s method of cataloging with methods of ludomusicological analysis2 will be useful for understanding the plethora of themes, motifs, source music, thematic relationships, lyrics, diegetic music, and ludomusical methods found within the scores of each game. To present an example of this combination of analyses, Lehman’s motifs (denoted by quotation marks) are presented in combination with original analyses and transcription by the author, demonstrating the overlap between the musical material of the Star Wars movies and video games. This series of catalogs would be an excellent resource for all future Star Wars ludomusicological research as well as further expanding the literature in the field.

Spatial interactions modulate tumor growth and immune infiltration

Direct observation of tumor-immune interactions is unlikely in tumors with currently available technology, but computational simulations based on clinical data can provide insight to test hypotheses. It is hypothesized that patterns of collagen evolve as a mechanism of immune escape, but the exact nature of immune-collagen interactions is poorly understood. Spatial data quantifying collagen fiber alignment in squamous cell carcinomas indicates that late-stage disease is associated with highly aligned fibers. Our computational modeling framework discriminates between two hypotheses: immune cell migration that moves (1) parallel or (2) perpendicular to collagen fiber orientation. The modeling recapitulates immune-extracellular matrix interactions where collagen patterns provide immune protection, leading to an emergent inverse relationship between disease stage and immune coverage. Here, computational modeling provides important mechanistic insights by defining a kernel cell-cell interaction function that considers a spectrum of local (cell-scale) to global (tumor-scale) spatial interactions. Short-range interaction kernels provide a mechanism for tumor cell survival under conditions with strong Allee effects, while asymmetric tumor-immune interaction kernels lead to poor immune response. Thus, the length scale of tumor-immune interaction kernels drives tumor growth and infiltration.

Longitudinal Study on the Pragmatic Language Skills during Play Activities in Preschool Children Who Stutter and Who do not Stutter

Objectives: This study aimed to investigate whether there are any differences in pragmatic language skills between preschool children who stutter (hereafter, CWS) and those who do not stutter (hereafter, CWNS) in natural play interactions with their parents. Additionally, the study sought to examine the relationship between pragmatic language skills and children’s stuttering. Methods: 7 CWNS and 7 CWS aged 2-5 years, and their parents participated in the study. In a total of three times at 12-month intervals, their interactions during play activities were collected to analyze abnormal disfluency (AD), normal disfluency (ND) frequency, and pragmatic language skills (initiation utterance of child, initiation of utterance of mother and utterance turn-taking). Between-group comparisons of variables were made by collection period (initial evaluation, 12 months later, 24 months later). Results: First, the AD frequency of the CWS group was statistically significantly higher than that of the CWNS group at the initial evaluation and at 12 months, and there was no significant difference between the two groups at 24 months. Second, the frequency of initiation of utterance in CWNS group was significantly higher than that of the CWS group in the initial evaluation. At 12 months and 24 months, children with stutter had a similar degree of initiation of utterance as that of typical children. Third, there was no significant difference between the CWS and CWNS group in utterance turn-taking. The difference in the frequency of utterances and turn-taking between CWS and CWNS group tended to increase over time. Conclusion: These findings confirmed that stuttering in children is influenced by their pragmatic language skills. This suggests the need for parent-child interaction and parental education programs that enhance children’s pragmatic language skills, which may positively impact fluency in CWS.

The Development of Geo-Math Application by Integrating Geo-Gebra Applets to Improve Students’ Spatial Ability

Geometry can be challenging for students due to its abstract nature; The difficulty is often associated with low spatial abilities; to overcome these challenges, educators can employ dynamic and visual learning approaches to help students learn and understand geometric concepts more effectively. This study aimed to develop a Geo Math application by integrating the GeoGebra applets on geometry that fulfill valid, practical, and effective aspects that are expected to improve spatial abilities. This research utilized development research using the ADDIE model, which consists of 5 stages: analysis, design, development, and trial implementation. It went through several trial stages consisting of validation experts, one-to-one trials, and small group trials, and the evaluation stage was carried out through a pre-post-test quasi-experimental study. Based on the results, it can be concluded that the Geo Math application was very feasible to support the implementation of learning mathematics, especially in learning geometric transformations, which could assist students in constructing concepts from various transformations effectively. The interactive and dynamic nature of GeoGebra applets within the application allowed students to visualize and manipulate geometric objects and could make abstract mathematical concepts more concrete and accessible, which could improve students’ spatial abilities.

Crystal Structure, Supramolecular Organization, Hirshfeld Analysis, Interaction Energy, and Spectroscopy of Two Tris(4-aminophenyl)amine-Based Derivatives

The use of tris(4-aminophenyl)amine (TAPA) as central to the synthesis of both polyimines and polyimides and covalent organic frameworks and inorganic cages, among others, has grown in the last few years. The resulting materials exhibit high performance in their area of application. In this contribution, the crystal structures of two TAPA derivatives, triethyl (nitrilotris(benzene-4,1-diyl))tricarbamate (1) and triethyl 2,2′,2″-((nitrilotris(benzene-4,1-diyl))tris(azanediyl))tris(2-oxoacetate) (2), are described. The molecular and supramolecular structures of both compounds were compared between them and with analogous compounds. The analyses of their vibrational and 13C-CPMAS NMR spectroscopies, as well as their thermal stability, were included and corelated with the crystal structure. Hirshfeld surface analysis on the crystal structures of both TAPA derivatives revealed the stabilization of the crystal network via the amide N—H∙∙∙O interactions of dispersive nature in the carbamate, whereas dispersive carbonyl–carbonyl interactions also played a competitive role in the supramolecular arrangement of the oxamate. Interaction energy DFT calculations performed at the B3LYP/6-31G(d,p) level allowed us to estimate the energy contributions and nature of several interactions in terms of the stability of both crystal lattices.
