Se extiende el ejercicio a tres niveles regionales: el mundo y regiones, América Latina y Argentina, durante 2000-2015. En este último caso, puede concluirse que el envejecimiento se asocia a los gastos incurridos previo al fallecimiento y una baja relevancia de “Enfermedad de costos” de Baumol.
Utilization of Used Wood as Material Structure and Construction of Sitinggil House Buildings
Authors: Pynkyawati Theresia , Lesmana Ekat , Sukendar Deden
Published: February 2022

Material plays an important role in the construction of a house because it becomes a constituent element for the establishment of a building. Sitinggil Dago Residence which is located on Jalan Dago Giri, Bandung, West Java is a house that has two functions. This house is interesting because overall it uses used wood as a structural and construction material by accentuating the structure of the building which is left as it is without finishing. The method used in this research is a descriptive analytical-qualitative method by observing the structure and construction of used wood on roofs, columns, and beams as well as the foundation as a base which is then compared with the theory and standardization of the use of wood in buildings. The results of this study show that used wood can still be reused for structures and construction on roofs, columns, and beams in residential buildings.
Transgressions: film recordings of the isolation period. Media studies analysis of short films inspired by the pandemic (HBO project)
Authors: Bożek Małgorzata
Published: February 2022

The review article is an attempt at a media studies analysis of short films made by Polish filmmakers commissioned by the HBO digital platform. They are all in response to the pandemic situation of isolation. The analysis deals with the transgression of artistic attitudes towards danger. In it, I use the tools of contemporary semiology: verbal and non-verbal codes that participate in creating meanings through destruction and a new reading of meanings hidden in film messages. I prove that artists, first of all, commit transgression, negating the existing reality and looking for a new film language that contradicts the Aristotelian structure of the three acts in order to disperse the images and meanings they carry. Secondly, I argue that the deconstruction of codes and the reassembly of meanings proposed by semiologists takes place in the artistic activities in question, as if in the opposite direction. Deconstruction – indeed, but not to discover the truth in a new context, but to look for it in bits of reality that function separately and do not create meanings. They are only separately illuminated and contoured images.

Competencias digitales y alfabetización mediática para una educación abierta y en línea
Authors: Dias-Trindade Sara , Moreira José António
Published: February 2022

We live in a society where physical and virtual reality are increasingly intertwined. The boundaries between the body and the imaginary gain new contours and definitions, affecting important and essential aspects, such as the power of participation and emancipation of the individual in the society in which he/she is inserted. The rapid pace of the technological and digital society makes it essential that both teachers and students know how to use different digital resources to create and develop learning environments that lead not only to the acquisition of knowledge, but also to scenarios that promote the development of different learning skills. Recently, the emphasis given to the relevance of digital competence has resulted in the development of various initiatives in Europe aimed at promoting digital and media competence. In addition, evaluating media in a critical and conscious way, developing the skills necessary to participate in an active and informed way in society, is considered today a fundamental competence for an increasingly mediated society and also for an education that increasingly moves in a fluid way between formal and non-formal spaces. To this end, it is necessary to rethink the objectives and methodologies of education, based on a concept of literacy that is continuously evolving, related to the skills needed to read, understand and communicate.

Authors: Lima Silva Larissa , Carrara Aniela Fagundes
Published: February 2022

O estudo considera a relevância que a pecuária tem para a questão alimentar e para economia brasileira, e tem como motivação a elevação, iniciada em meados de 2019, dos preços de alguns produtos que compõem tal setor, por conta principalmente do aumento da demanda externa. Assim, o objetivo do presente trabalho é entender e quantificar o impacto dos preços da pecuária no grupo alimentação e bebidas do Índice de Preços ao Consumidor Amplo - IPCA, de modo a identificar sua durabilidade e sua relevância para tal segmento, que compõe o índice de preços oficial do país. Visando cumprir tal objetivo, é estruturado um modelo baseado na curva de Phillips, cuja estimação é implementada por meio de Vetores Autorregressivos com Correção da Erros, na modalidade estrutural. Os resultados obtidos apontam que os preços da pecuária têm efeito positivo, significativo e de montante considerável sobre a inflação do grupo alimentação e bebidas e que contribuíram para que esta se elevasse nos anos de 2019 e 2020.
LEI DE ACESSO À INFORMAÇÃO E CURADORIA DE DADOS PÚBLICOS: O “JORNALISMO DE VERIFICAÇÃO” COMO TIPO IDEAL
Authors: Seibt Taís
Published: February 2022

Apesar de ser frequentemente associado à prática jornalística de fact-checking (verificação de fatos), o “jornalismo de verificação” enquanto tipo ideal (SEIBT, 2019) abrange mudanças estruturais mais amplas, podendo ser associado a outras práticas, como a curadoria de conteúdos, incluídas bases de dados. A partir desse modelo teórico, o artigo problematiza o uso de ferramentas de transparência pública previstas na Lei de Acesso à Informação, tensionando seus limites e potencialidades frente à desinformação (WARDLE; DERAKHSHAN, 2017) e às mudanças estruturais do jornalismo (CHARRON; BONVILLE, 2016).
Comparison of Plasma Ionization- and Secondary Electrospray Ionization- High-resolution Mass Spectrometry for Real-time Breath Analysis
Authors: Zeng Jiafa , Christen Alexandra , Dev Singh Kapil , Frey Urs , Sinues Pablo
Published: February 2022

Real-time breath analysis by high-resolution mass spectrometry (HRMS) is a promising method to noninvasively retrieve relevant biochemical information. In this work, we conducted a head-to-head comparison of two ionization techniques: Secondary electrospray ionization (SESI) and plasma ionization (PI), for the analysis of exhaled breath. Two commercially available SESI and PI sources were coupled to the same HRMS device to analyze breath of two healthy individuals in a longitudinal study. We analyzed 58 breath specimens in both platforms, leading to 2,209 and 2,296 features detected by SESI-HRMS and by PI-HRMS, respectively. 60% of all the mass spectral features were detected in both platforms. However, remarkable differences were noted in terms of the signal-to-noise ratio (S/N), whereby the median (interquartile range, IQR) S/N ratio for SESI-HRMS was 115 (IQR = 408), whereas for PI-HRMS it was 5 (IQR = 5). Differences in the mass spectral profiles for the same samples make the inter-comparability of both techniques problematic. Overall, we conclude that both techniques are excellent for real-time breath analysis because of the very rich mass spectral fingerprints. However, further work is needed to fully understand the exact metabolic insights one can gather using each of these platforms.
Visualization, Interactive Handling and Simulation of Molecules in Commodity Augmented Reality in Web Browsers Using moleculARweb’s Virtual Modeling Kits
Authors: Cortes Rodriguez Fabio , Krapp Lucien , Dal Peraro Matteo , Abriata Luciano
Published: February 2022

moleculARweb (https://molecularweb.epfl.ch) began as a website for education and outreach in chemistry and structural biology through augmented reality (AR) content that runs in the web browsers of regular devices like smartphones, tablets, and computers. Here we present two evolutions of moleculARweb’s Virtual Modeling Kits (VMK), tools where users can build and view molecules, and explore their mechanics, in 3D AR by handling the molecules in full 3D with custom-printed cube markers (VMK 2.0) or by moving around a simulated scene with mouse or touch gestures (VMK 3.0). Upon simulation the molecules experience visually realistic torsions, clashes, and hydrogen-bonding interactions that the user can manually switch on and off to explore their effects. Moreover, by manually tuning a fictitious temperature the users can accelerate conformational transitions or 'freeze' specific conformations for careful inspection in 3D. Even some phase transitions and separations can be simulated. We here showcase these and other features of the new VMKs connecting them to possible specific applications to teaching and self-learning of concepts from general, organic, biological and physical chemistry; and in assisting with small tasks in molecular modelling for research. Last, in a short discussion section we overview what future developments are needed for the 'dream tool' for the future of chemistry education and work.
The Emerging Potential of Advanced Targeted Mass Spectrometry to Become a Routine Tool for Protein Quantification in Biomedical Research
Authors: Schmidt Alexander , Varela Minia Antelo
Published: February 2022

Mass spectrometry-based proteomics has become an indispensable tool for system-wide protein quantification in systems biology, biomedical research, and increasing for clinical applications. In particular, targeted mass spectrometry offers the most sensitive and reproducible quantitative detection of proteins, peptides and post-translational modifications of any currently applied mass spectrometry technique and is therefore ideally suited to generate high quality quantitative datasets. Despite these apparent advantages, targeted mass spectrometry is only slowly gaining popularity in academia and pharmaceutical industries, mainly due to the additional efforts in assay generation and manual data validation. However, with the increasing accumulation of mass spectrometry data, advances in deep learning spectral prediction for automated assay development, these obstacles can and will be considerably reduced in the near future. Here, we describe the latest technological developments in this field and discuss the emerging importance of targeted mass spectrometry for systems biology research and potential key roles in bridging biomedical discovery and clinical implementation.
Metropolis logistics challenges the formation of inter-organizational relationships
Authors: Kos Barbara , Figura Janusz
Published: February 2022

Metropolis logistics is a new research issue that begins to play an important role in shaping inter-organizational relationships. The concept of logistics in metropolitan terms is a contemporary term used primarily to identify issues that will improve the transformation of products and information in building inter-organizational efficiency. On the one hand, the issues of metropolitan logistics are based on shaping the flow of products and information in building inter-organizational efficiency. On the other hand, the formation of inter-organizational bonds has a complex and multidimensional structure that creates a specific network of interactions in which metropolitan logistics determines their development in relation to the environment. The aim of the article is to identify the conditions that build up inter-organizational relations within the Silesian-Zagłębie (Ś-Z) metropolitan area. The article presents selected results of exploratory research carried out among logistic entities operating in the Silesian-Zagłębie metropolitan area. The authors attempted to answer the question: what are the challenges facing metropolitan logistics in shaping inter-organizational relationships?
Major Features of Adaptive Supply Chains – Literature Review
Authors: Leończuk Dorota
Published: February 2022

Adaptiveness is one of the most significant features of the supply chain that affects the results of its functioning. The capability of the supply chain to adapt to all, more and more demanding conditions is one of the main factors that guarantee long-term competitiveness and success. R. Kalakota, M. Robinson and P. Gundepudi consider inventory visibility, fulfilment velocity and coordination versatility as three fundamental pillars of adaptive supply chains, also termed as 3V in the literature. The chief objective of this paper is the identification of features that a supply chain should have in order to be called adaptive, as well as the verification of their compliance with the 3V principle. The review of the available literature sources that focus on the subject of the major features of adaptive supply chains (in particular having a decisive effect on their adaptive capabilities) has resulted in certain common elements. The authors of all the described approaches emphasise the two features: visibility and velocity. The third, frequently indicated, feature is also versatility or variety (that can be treated as one of the elements of the versatility of the supply chain). Visibility involves ensuring access to the information for all participants in the supply chain, also customers. Velocity, in turn, refers to the reaction time of the supply chain to all sorts of events and the time of implementing necessary changes. The third element is versatility. It primarily involves balancing the operational capability of a supply chain with market requirements, in particular delivering suitable products and services of the required quality and in the ordered volume. It is also vital to adjust the offer to the individual needs of customers.
The Influence of Public Transport Acts in 2019 in Poland on Conflicts Concerning the Shape of the Public Transport Network
Authors: Augustyn Duszan
Published: February 2022

In 2019, the Polish Government introduced a new legislation on public transport. The main objective of these laws is to determine a new division of responsibilities within the public administration system for the planning, implementation and financing of public transport. These new regulations may significantly affect the scope of responsibilities and competencies of transport organizers, in particular regarding the creation of transport plans and funding mechanisms. As a result of maintaining an under-financed, unsustainable transport system based solely on commercial public transport for more than two decades, Poland has experienced a collapse of the public transport system in remote areas. The absence of complex policies in the field of public transport has caused millions of people to suffer from transport exclusion, especially in settlements located outside the main transport routes. This is resulting in disputes over the structure of the regional transport network. The aim of the research paper is to identify potential axes of conflicts between transport organizers, government and local governments subsidizing co-financed transport services, passengers and companies providing public and commercial passenger transport.

The subject of the article concerns the stabilization of communication earthworks using the so-called lightweight retaining structures. The stability of the embankment with the embankment built with the gabion wall is analysed, assuming a uniformly distributed load on the crown and a case of unilateral water pressure in the event of a flood. Final results of stability calculations made with the Fellenius and Bishop method in the form of slip surface with the smallest value of the coefficient were presented. Then, assuming the case of damming up of flood water, discretization of the filtration area, velocity distribution and hydrodynamic grating and slip surfaces were developed. The variable parameter is the wall configuration.
ENVIRONMENTALLY SUSTAINABLE TRANSPORT PLANNING IN THE SUPPLY CHAIN’S FIRST AND LAST MILE SECTION
Authors: Sierpiński Grzegorz , Staniek Marcin
Published: February 2022

Background: The article provides a discussion on freight transport planning. The existing solutions applied in this sphere have been compared with environment-related needs. The concept which has been proposed involves a dedicated travel planner that takes some additional non-standard criteria into consideration. At the same time, the authors have highlighted the necessity to expand the algorithms being applied and to address the comprehensive nature of the problem. However, it is the first and last mile section of supply chains on which the article focuses. The planner described in the paper is being developed as a part of an integrated platform implemented under the international S-mile project. Research methodology: The solutions proposed for transport planning purposes include application of ICT. A review of the available solutions has made it possible to indicate one of the planner currently in use as the foundation upon which a more advanced freight transport planning tool dedicated to the first/last mile section can be built. The planner requires application of several optimisation algorithms, including those which consider route parameters, the selection of fleet vehicles available for the given task, cargo distribution over the vehicle etc. The article defines primary as well as secondary criteria that such a planner should take into account, including the environmental ones. What the authors have also highlighted is the possibility to make use of open data sources. The approach they have proposed makes it possible to raise the level of environmental awareness at the first and the last mile management stage, and since multiple transport aspects have been addressed, it also increases planning efficiency. Goals: The purpose of the article has been to discuss an eco-friendly solution which may limit the negative environmental impact of transport. Conclusions: The solution described in the paper may change the manner in which freight transport is managed in cities. Taking environmental criteria into consideration makes it possible to reduce the negative environmental impact of transport. Planning of freight transport requires that far more criteria should be taken into account compared to route planning for the travelling population. A comprehensive fleet management platform featuring a planning module combined with other modules of the S-mileSys system being currently developed is also aimed at integration of large freight companies with the carriers that service first and last miles.

Companies managing supply chains are increasingly facing a decision to migrate or start operating in the digital world. Gaining competitive advantage by supply chain management means sharing the information as the evidence of trust between partners. Digital Supply Chains are based on technologies that enable increasing competitiveness mainly by delivering information in real time simultaneously to many supply chain partners. However the type and range of the information shared indicates the level of trust. Research results show that partners in supply chain were sharing information about inventory and transport activities. These are the main areas of competing by logistics and supply chain management. The aspect of partnership and cooperation was also raised in the research. Cloud computing had been willingly used in Supplier Relationship Management, Customer Relationship Management and Customer Service Management processes by the respondents.
Negation of logistics rules in managing the operation of motorways in Poland
Authors: Czyrka Krzysztof , Frąś Józef , Borowiecka Olga , Frąś Marcin
Published: February 2022

Costs for tolling a motorway in Poland should take into account not only profits of owners and managers, but also difficulties and losses incurred by road users. Lack of liquidity of travel, high tolls do not have a positive impact on the country's economic development. The nervousness and stress of drivers and passengers trapped in cars standing in traffic jams in front of the gates on motorways, they indicate an important social problem. The costs of fuel burned during forced stops, costs of harmful effects on the environment, pollution from car exhaust emissions while waiting on the highway before the gates are a significant burden. Failure to ensure the conditions for a smooth ride causing the need to wait on the highway before the gates is an example of disregarding people, wastage and deliberate harm to the environment for disproportionate profits charges for using the highways.
The Use of the EOQ Model in Inventory Management in the Supply Chain on the Example of Bahlsen Polska
Authors: Paluch Waldemar
Published: February 2022

The article presents the theoretical basis of the EOQ (economic quantity order) model, which allows you to optimize the size of the order so as to minimize the cost of frozen capital. The next part presents the results of implementing the model at Bahlsen Polska, assuming that it does not receive any discounts from suppliers in relation to the size of the order. This assumption can be excluded in the case of the functioning of the disposition system, carried out taking into account large contracts with the supplier. Optimization in this situation does not apply to the quantity in the contract, but only to a single call, which is information for the supplier who must deliver a certain amount of goods and at the same time reduce the balance appearing in the contract.

Electric-Car-Sharing in Urban Logistics – The Analysis of Implementation and Maintenance
Authors: Turoń Katarzyna , Sierpiński Grzegorz
Published: February 2022

The implementation of the sustainable transport policy in cities aims at finding various solutions that support the use of ‘clean energy’ in urban logistics. One of current global sustainable transport trends involves various measures related to electromobility. An example of electromobility in urban logistics is the e-car-sharing, or a short-term electric car rental. Since electric car-sharing is rather new to the transport market, operators and cities and metropolises may face various difficulties while implementing such services. Based on still operating and discontinued e-car-sharing systems, the authors analysed strengths and weaknesses of those systems with the focus on implementation and maintenance issues. The goal of the article is to determine strengths and challenges for e-car-sharing in urban logistics. The article is designed to assist stakeholders interested in the implementation of e-car-sharing. The analysis was provided under the international research project of ‘Electric travelling platform to support the implementation of electromobility in Smart Cities based on ICT applications’ funded from the National Research and Development Centre as a part of the ERA-NET CoFund Electric Mobility Europe Programme.

Published: February 2022

The reliability of supply of the logistics systems is the one of the most important factors determining the competitiveness of businesses. The main purpose of this paper is to assess the reliability of supply of a given system with the use of warranty analysis, based on the Nevada chart. The reliability analysis performed is done in the following way: shipping and warranty return data of a given supply system are converted into a classic data form. Then, the life data analysis is performed, which allows to obtain the given reliability indicators and predict the future returns of the products and services. The paper consists of some useful reliability measures, that may be used in the assessment of reliability for the supply system. Used reliability indicators may be the basis for the development of the preventive tasks to reduce the future returns. The presented approach for reliability assessment of supply system discloses its applicability. Forecasting the future returns and determining the selected reliability measures may be applied in any supply system. It is valuable for the identification of the weakest product or service and it is necessary for developing further preventive activities.

Retaining walls have been classified and characterized as structures protecting road or railway embankments against landslides. Particular attention was focused on retaining structures classified as light [1-3, 5-12, 14-24], which include, among others, walls made of gabions. Physical models of the gabion retaining wall, prepared on a laboratory scale, test stand and how to perform spatial deformation tests are presented. The models differed in the number and dimensions of gabions. On the basis of measured horizontal deformations of embankment models with a gabion wall, which were subjected to vertical static pressure at the level of the embankment ceiling, the values of basic strength parameters were determined. In particular, the value calculated: horizontal pressure coefficient, shear strength and modulus of deformation. The variability of the values of these parameters was estimated as a function of variable factors related to the gabion wall configuration (determined by the number and dimensions of gabions) and the value of the external load test.

Ultrahigh-resolution Fourier transform mass spectrometry (FTMS) has revealed unprecedented detail of natural complex mixtures such as dissolved organic matter (DOM) on a molecular formula level, but we lack approaches to access the underlying structural complexity. We here explore the hypothesis that every DOM precursor is potentially linked with all emerging product ions in FTMS2 experiments. The resulting mass difference (Δm) matrix is deconvoluted to isolate individual precursor Δm profiles and matched with structural information, which was derived from 42 Δm features from 14 in-house reference compounds and a global set of 11477 Δm features with assigned structure specificities, using a dataset of ~18000 unique structures. We show that Δm matching is highly sensitive in predicting potential precursor identities in terms of molecular and structural composition. Additionally, the approach identified unresolved precursors and missing elements in molecular formula annotation (P, Cl, F). Our study provides first results how Δm matching improves structural domains in Van Krevelen space, but simultaneously demonstrates the wide overlap between the structural domains. We show that this effect is likely driven by chemodiversity and offers an explanation for the observed ubiquitous presence of molecules in the center of the Van Krevelen space. Our promising first results suggest that Δm matching can unfold the structural information encrypted in DOM and assess the quality of FTMS-derived molecular formulas of complex mixtures in general.

Using the dinitrosobenzene polymer (1) as an example, we explore how the electronic, transport, and optical properties of a conjugated organic semiconductor can be modulated. Combining computational and experimental tools, we explore the effects of solid-state packing, backbone torsion, surface adsorption, the conjugation in the aromatic core, and substituents. The band gap (Eg) and optical spectrum of 1 are calculated using both GW-BSE with zero-gap renormalization (ZGR) and hybrid TD-DFT, with the former method predicting a value (2.41 eV) in excellent agreement with our diffuse reflectance spectroscopy measurements (2.39 eV). Using GW-BSE-ZGR, changes occurring upon solid-state packing are separated into a contribution arising from (i) the change in the torsional angle and (ii) the change in the screened Coulombic interaction, which strongly affects the exciton binding energies. Comprehensive hybrid TD-DFT calculations find that the effects of substituents on Eg and on transport properties can mostly be explained through changes in the torsional angle t, and predict a linear dependence between t and Eg. Extending the conjugation in the aromatic core is found to enhance transport properties and narrow Eg, identifying future synthetic targets. Atomic force microscopy and spectroscopic ellipsometry are used to study 1 adsorbed to a (111) gold surface (1@Au), with the latter method showing a significant narrowing of the band gap to 0.68 eV, in good agreement with TD-DFT predictions.

Each year, millions of premature deaths worldwide are caused by exposure to outdoor air pollution, especially fine particulate matter (PM2.5). Designing policies to reduce these deaths relies on air quality modeling for estimating changes in PM2.5 concentrations from many scenarios at high spatial resolution. However, air quality modeling typically has substantial requirements for computation and expertise, which limits policy design, especially in countries where most PM2.5-related deaths occur. Lower requirement reduced-complexity models exist but are generally unavailable worldwide. Here, we adapt InMAP, a reduced-complexity model originally developed for the United States, to simulate annual-average primary and secondary PM2.5 concentrations across a global-through-urban spatial domain: “Global InMAP”. Global InMAP uses a variable resolution grid, with horizontal grid cell widths ranging from 500 km in remote locations to 4km in urban locations. We evaluate Global InMAP performance against both measurements and a state-of-the-science chemical transport model, GEOS-Chem. Against measurements, InMAP predicts total PM2.5 concentrations with a normalized mean error of 62%, compared to 41% for GEOS-Chem. For the emission scenarios considered, Global InMAP reproduced GEOS-Chem pollutant concentrations with a normalized mean bias of 59%–121%, which is sufficient for initial policy assessment and scoping. Global InMAP can be run on a desktop computer; simulations here took 2.6–8.4 hours. This work presents a global, open-source, reduced-complexity air quality model to facilitate policy assessment worldwide, providing a screening tool for reducing air pollution-related deaths where they occur most.

Water oxidation is the step limiting the efficiency of electrocatalytic hydrogen production from water. Spectroelectro-chemical analyzes are employed to make a direct comparison of water oxidation reaction kinetics between a molecu-lar catalyst, the dimeric iridium catalyst [Ir2(pyalc)2(H2O)4-(µ-O)]2+ (IrMolecular, pyalc = 2-(2’pyridinyl)-2-propanolate) immobilized on a mesoporous indium tin oxide (ITO) substrate, with that of an heterogenous electrocatalyst, an amorphous hydrous iridium (IrOx) film. For both systems, four analogous redox states were detected, with the for-mation of Ir(4+)-Ir(5+) being the potential-determining step in both cases. However, the two systems exhibit distinct water oxidation reaction kinetics, with potential-independent first-order kinetics for IrMolecular contrasting with poten-tial-dependent kinetics for IrOx. This is attributed to water oxidation on the heterogenous catalyst requiring co-operative effects between neighboring oxidized Ir centers. The ability of IrMolecular to drive water oxidation without such co-operative effects is explained by the specific coordination environment around its Ir centers. These distinc-tions between molecular and heterogenous reaction kinetics are shown to explain the differences observed in their water oxidation electrocatalytic performance under different potential conditions.

Number sequences, like Fibonacci, Fermat, Markov, Euler, Bernoulli, etc., have been popular in exemplifying a variety of scientific phenomena. Here, we explore the Catalan numbers in the context of ABm step polymerisation and develop a framework to derive its alternative closed form expression. Our approach harnesses the concepts of combinatorics and graph theory, in conjunction with kinetics of AB2 polymerisation to obtain the chain length distribution that directly gives the closed-form expression of Catalan number expressed as a bivariate distribution function. Furthermore, we validate our expression by comparing first 5000 Catalan numbers obtained from its traditional closed-form. As an offshoot, we discuss “pathwidth”, a construct used in graph theory, as a better metrics for describing topology of polymer chains. The framework developed in this work can be extended to ABm step polymerisation and thus, facilitates topological characterisation of hyperbranched polymers (HPs) that ultimately, dictates their structure-property relationships.
