Interstellar Dust Inside and Outside the Heliosphere

Subjects: subject: Astrophysics (astro-ph)

description: In the early 1990s, after its Jupiter flyby, the Ulysses spacecraft identified interstellar dust in the solar system. Since then the in-situ dust detector on board Ulysses continuously monitored interstellar grains with masses up to 10e-13 kg, penetrating deep into the solar system. While Ulysses measured the interstellar dust stream at high ecliptic latitudes between 3 and 5 AU, interstellar impactors were also measured with the in-situ dust detectors on board Cassini, Galileo and Helios, covering a heliocentric distance range between 0.3 and 3 AU in the ecliptic plane. The interstellar dust stream in the inner solar system is altered by the solar radiation pressure force, gravitational focussing and interaction of charged grains with the time varying interplanetary magnetic field. The grains act as tracers of the physical conditions in the local interstellar cloud (LIC). Our in-situ measurements imply the existence of a population of 'big' interstellar grains (up to 10e-13 kg) and a gas-to-dust-mass ratio in the LIC which is a factor of > 2 larger than the one derived from astronomical observations, indicating a concentration of interstellar dust in the very local interstellar medium. Until 2004, the interstellar dust flow direction measured by Ulysses was close to the mean apex of the Sun's motion through the LIC, while in 2005, the data showed a 30 deg shift, the reason of which is presently unknown. We review the results from spacecraft-based in-situ interstellar dust measurements in the solar system and their implications for the physical and chemical state of the LIC.

description: In theory, quantum key distribution (QKD) offers unconditional security based on the laws of physics. However, as demonstrated in recent quantum hacking theory and experimental papers, detection efficiency loophole can be fatal to the security of practical QKD systems. Here, we describe the physical origin of detection efficiency mismatch in various domains including spatial, spectral, and time domains and in various experimental set-ups. More importantly, we prove the unconditional security of QKD even with detection efficiency mismatch. We explicitly show how the key generation rate is characterized by the maximal detection efficiency ratio between the two detectors. Furthermore, we prove that by randomly switching the bit assignments of the detectors, the effect of detection efficiency mismatch can be completely eliminated.

title: A Decade of Irish Literary Periodicals: 1904-1914
Creators: name: Dunning, DL
Publisher: name: University of Liverpool Repository
Year: 2017

description: This thesis examines the history and development of three Irish periodicals, published between 1904-1914, with emphasis placed upon the literary magazine as a distinct genre and the impact of this genre on the literary and cultural landscape of Ireland at a crucial time in its nascent development. My research considers the manner in which each magazine was established and run, with an emphasis on varying editorial personalities and their impact upon each periodical. Each chapter is dedicated to an individual magazine and is structured in chronological order, with the first focused upon Dana, the second dedicated to Uladh (both published from 1904-1905) and the final chapter focused upon The Irish Review (1911-1914). The aim is to provide an assessment of those journals, acknowledging how key figures of the period made use of their pages to promote their own views and the movements that they supported. This thesis will emphasise the significance of the literary magazine as a historical resource that reveals much about the period in which it was published. Until now the history of these literary periodicals has remained largely untold, as have the events surrounding the lives of their editors and contributors during their publication years. My primary purpose is to tell these stories in the detail they deserve.
Fundamental solutions and Hadamard states for a scalar field with arbitrary boundary conditions on an asymptotically AdS spacetimes

description: We consider the Klein-Gordon operator on an $n$-dimensional asymptotically anti-de Sitter spacetime $(M,g)$ together with arbitrary boundary conditions encoded by a self-adjoint pseudodifferential operator on $\partial M$ of order up to $2$. Using techniques from $b$-calculus and a propagation of singularities theorem, we prove that there exist advanced and retarded fundamental solutions, characterizing in addition their structural and microlocal properties. We apply this result to the problem of constructing Hadamard two-point distributions. These are bi-distributions which are weak bi-solutions of the underlying equations of motion with a prescribed form of their wavefront set and whose anti-symmetric part is proportional to the difference between the advanced and the retarded fundamental solutions. In particular, under a suitable restriction of the class of admissible boundary conditions and setting to zero the mass, we prove their existence extending to the case under scrutiny a deformation argument which is typically used on globally hyperbolic spacetimes with empty boundary.

description: The greatest challenge in maximizing the use of gene expression data is to develop new computational tools capable of interconnecting and interpreting the results from different organisms and experimental settings. We propose an integrative and comprehensive approach including a super-chip containing data from microarray experiments collected on different species subjected to hypoxic and anoxic stress. A data mining technology called Peano count tree (P-trees) is used to represent genomic data in multidimensions. Each microarray spot is presented as a pixel with its corresponding red/green intensity feature bands. Each bad is stored separately in a reorganized 8-separate (bSQ) file format. Each bSQ is converted to a quadrant base tree structure (P-tree) from which a superchip is represented as expression P-trees (EP-trees) and repression P-trees (RP-trees). The use of association rule mining is proposed to derived to meanigingfully organize signal transduction pathways taking in consideration evolutionary considerations. We argue that the genetic constitution of an organism (K) can be represented by the total number of genes belonging to two groups. The group X constitutes genes (X1,Xn) and they can be represented as 1 or 0 depending on whether the gene was expressed or not. The second group of Y genes (Y1,Yn) is expressed at different levels. These genes have a very high repression, high expression, very repressed or highly repressed. However, many genes of the group Y are specie specific and modulated by the products and combinations of genes of the group X. In this paper, we introduce the dSQ and P-tree technology; the biological implications of association rule mining using X and Y gene groups and some advances in the integration of this information using the BRAIN architecture.

description: Several technologies are emerging that provide new ways to capture, store, present and use knowledge. This book is the first to provide a comprehensive introduction to five of the most important of these technologies: Knowledge Engineering, Knowledge Based Engineering, Knowledge Webs, Ontologies and Semantic Webs. For each of these, answers are given to a number of key questions (What is it? How does it operate? How is a system developed? What can it be used for? What tools are available? What are the main issues?). The book is aimed at students, researchers and practitioners interested in Knowledge Management, Artificial Intelligence, Design Engineering and Web Technologies. During the 1990s, Nick worked at the University of Nottingham on the application of AI techniques to knowledge management and on various knowledge acquisition projects to develop expert systems for military applications. In 1999, he joined Epistemics where he worked on numerous knowledge projects and helped establish knowledge management programmes at large organisations in the engineering, technology and legal sectors. He is author of the book "Knowledge Acquisition in Practice", which describes a step-by-step procedure for acquiring and implementing expertise. He maintains strong links with leading research organisations working on knowledge technologies, such as knowledge-based engineering, ontologies and semantic technologies.

description: We present a detailed description of the diagrammatic technique, recently devised in [V. V. Kuzmin et.al., npj Quantum Information 5, 115 (2019)], for semi-analytical description of large-scale quantum-repeater networks. The technique takes into account all essential experimental imperfections, including dissipative Liouville dynamics of the network quantum memories and the classical communication delays. The results obtained with the semi-analytic method match the exact Monte Carlo simulations while the required computational resources scale only linearly with the network size. The presented approach opens new possibilities for the development and efficient optimization of future quantum networks.
Neural methods for document understanding

Publisher: name: No Publisher Supplied

description: Document recognition involves both structured and unstructured data. This dissertationstudies and proposes solutions to problems in both domains. Structured data often comes in tabular format. Many existing applications use structured tables as input such as spreadsheets, HTML, Excel, and CSV. However, there are a plethora of circumstances that can lead to generating images of tables (scanning invoices, sharing user manuals, downloading read-only publications, etc.). In such scenarios, we do not have access to the table structure. To be able to use the aforementioned applications in the given scenarios, we focus on the problem of structure recognition by graph modeling. We are investigating ways of inferring the hidden structures from tables’ images. By extracting table fields in the form of an undirected graph G and finding the corresponding Line graph L(G), AKA edge-to-vertex dual graph, we are able to model the structure-inference problem as a vertex classification. We approach the graph vertex classification problem using the Graph Convolutional Network (GCN) based model. GCNs process graphs using graph convolution process analogous to how Convolution Neural Networks (AKA CNNs) process images using convolution. In the context of graphs, the convolution process is re-adjusted to treat a vertex and its neighboring vertices analogous to how a pixel and its neighboring pixels would be processed in a filtering/convolution process. For unstructured text data, category recognition has many applications (e.g. taxes, government forms, insurance, bills and invoices). We focus on the problem of text classification in both English and Multilingual settings.For text data, unsupervised neural transfer learning from language modeling enables better text representation. A representation that reflects the semantic meanings of the represented words and semantic relations between them (generative pre-training). We investigate generative pre-training based models to approach text classification.We focus on text classification in three settings: English, multilingual and Arabic. We use generative pre-training models to do the text classification tasks. We evaluated State of the Art generative pre-training models on English data sets. Then, we fix the model and apply it as is on Korean, Arabic and Spanish. Finally, we fix the language (Arabic), use three different language-enabled models (not as is). We use the following generative pre-training models: ULMFiT, BERT and XLM. ULMFiT depends on LSTM while Bert and XLM adopt Transformer architecture instead demonstrating that convolution can be abandoned and still generate State of the Art results. XLM adds a Translation based objective function, which considers knowledge learned from data sets belonging to different languages. This makes it a good candidate in our setting.

description: In the Standard Model, scalar contributions to leptonic and semileptonic decays are helicity suppressed. The hypothesis of additional physical neutral/charged Higgses can enhance such scalar contributions and give detectable effects especially in B physics. For the charged Higgs, experimental information on both Br(B -> D tau nu) and Br(B -> tau nu) has already become available and in particular the B -> D tau nu branching ratio measurements will be further improved in the coming years. Hadronic uncertainties of scalar contributions in semileptonic decays are already in much better shape than the ones plaguing the helicity suppressed leptonic decays B -> tau nu. Combining existing experimental information form the B factories, we explore which existing and future lattice estimates will be useful to directly address new physics effects from measurements of Br(B_{u,d,s} -> D_{u,d,s} tau nu), which can be performed also at hadron colliders.

description: We present here the transmission of electromagnetic waves through layered structures of metallic and left-handed media. Based on the theory of finite periodic systems, we show that besides the strong influence of the incidence angle, the low transmission characteristic of a single conductor slab, for frequencies $ω$ below the plasma frequency $ω_p$, becomes in this domain highly oscillating. Similarly, the well-established transmission coefficient of a single left-handed slab becomes highly resonant with superluminal effects in superlattices with more than one unit cell. We determine the space-time evolution of a wave packet through the $λ/4$ photonic superlattice whose transmission coefficient is a sequence of isolated and equidistant peaks with negative phase times. We show that the space-time evolution of a Gaussian wave packet, with centroid at any of these peaks, agrees with the theoretical predictions, and no violation of the causality principle occurs. We show that besides the strong influence of the incidence angle, the coherent coupling of the bulk plasmon modes and the interface surface plasmon polaritons lead to oscillating transmission coefficients, and depending on the parity of the number of unit cells $n$ of the superlattice, the transmission vanishes or amplifies as the conductor width increases. We determine the space-time evolution of a wave packet through the $λ/4$ photonic superlattice whose bandwidth becomes negligible, and the transmission coefficient becomes a sequence of isolated and equidistant peaks with negative phase times. We show that the space-time evolution of a Gaussian wave packet, with the centroid at any of these peaks, agrees with the theoretical predictions, and no violation of the causality principle occurs.

The canzoni da sonar con ogni sorte d’istromenti, 1625 of Giovanni Picchi
Creators: name: Wilkes, Nathan Garrison
Publisher: name: University of British Columbia
Year: 2009

description: Giovanni Picchi (c. 1572 - 1643) was a Venetian composer and keyboard player active in the early seventeenth century. His Canzoni da sonar con ogni sorte d'istromente (1625) is a diverse set of nineteen ensemble canzonas in two to eight parts. Unusually for this period, Picchi specifies precise instrumentation in much of the collection, including violin, recorder, cornetto, trombone, bassoon, and organ; trombone, violin, and organ being the predominant instruments. The compositional style generally follows the tradition of Giovanni Gabrieli. This document places the Canzoni da sonar in an historical context, and provides insight into the canzonas themselves. A transcription of the entire collection is included.

title: On the birational geometry of singular Fano varieties.
Creators: name: Johnstone, E
Publisher: name: University of Liverpool Repository
Year: 2017

description: This thesis investigates the birational geometry of a class of higher dimensional Fano varieties of index 1 with quadratic hypersurface singularities. The main investigating question is, what structures of a rationally connected fibre space can these varieties have? Two cases are considered: double covers over a hypersurface of degree two, known as double quadrics and double covers over a hypersurface of degree three, known as double cubics. This thesis extends the study of double quadrics and cubics, first studied in the non-singular case by Iskovskikh and Pukhlikov, by showing that these varieties have the property of birational superrigidity, under certain conditions on the singularities of the branch divisor. This implies, amongst other things, that these varieties admit no non-trivial structures of a rationally connected fibre space and are thus non-rational. Additionally, the group of birational automorphisms coincides with the group of regular automorphisms. This is shown using the ``Method of maximal singularities" of Iskovskikh and Manin, expanded upon by Pukhlikov and others, in conjunction with the connectedness principal of Shokurov and Kollar. These results are then used to give a lower bound on the codimension of the set of all double quadrics (and double cubics) which are either not factorial or not birationally superrigid, in the style of the joint work of Pukhlikov and Eckl on Fano hypersurfaces. Such a result has applications to the study of varieties which admit a fibration into double quadrics or cubics.

description: With the advent of interferometric instruments with 4 telescopes at the VLTI and 6 telescopes at CHARA, the scientific possibility arose to routinely obtain milli-arcsecond scale images of the observed targets. Such an image reconstruction process is typically performed in a Bayesian framework where the function to minimize is made of two terms: the datalikelihood and the Bayesian prior. This prior should be based on our prior knowledge of the observed source. Up to now,this prior was chosen from a set of generic and arbitrary functions, such as total variation for example. Here, we present an image reconstruction framework using generative adversarial networks where the Bayesian prior is defined using state-of-the-art radiative transfer models of the targeted objects. We validate this new image reconstruction algorithm on synthetic data with added noise. The generated images display a drastic reduction of artefacts and allow a more straight forward astrophysical interpretation. The results can be seen as a first illustration of how neural networks can provide significant improvements to the image reconstruction of a variety of astrophysical sources.

description: This paper is concerned with the Einstein equations in axisymmetric vacuum spacetimes. We consider numerical evolution schemes that solve the constraint equations as well as elliptic gauge conditions at each time step. We examine two such schemes that have been proposed in the literature and show that some of their elliptic equations are indefinite, thus potentially admitting nonunique solutions and causing numerical solvers based on classical relaxation methods to fail. A new scheme is then presented that does not suffer from these problems. We use our numerical implementation to study the gravitational collapse of Brill waves. A highly prolate wave is shown to form a black hole rather than a naked singularity.

description: Deep neural networks provide flexible frameworks for learning data representations and functions relating data to other properties and are often claimed to achieve 'super-human' performance in inferring relationships between input data and desired property. In the context of inelastic neutron scattering experiments, however, as in many other scientific scenarios, a number of issues arise: (i) scarcity of labelled experimental data, (ii) lack of uncertainty quantification on results, and (iii) lack of interpretability of the deep neural networks. In this work we examine approaches to all three issues. We use simulated data to train a deep neural network to distinguish between two possible magnetic exchange models of a half-doped manganite. We apply the recently developed deterministic uncertainty quantification method to provide error estimates for the classification, demonstrating in the process how important realistic representations of instrument resolution in the training data are for reliable estimates on experimental data. Finally we use class activation maps to determine which regions of the spectra are most important for the final classification result reached by the network.

description: A digital porous media laboratory comprises a set of techniques to analyse and characterize samples using computer simulations and digital measurements to predict or determine material properties. This thesis has implemented the complete workflow of this technique from sample preparation until reporting the gained information pertaining said sample. A complete design of an in house built X-ray computed tomographic system is described. All components of the system are listed and the way they are electrically and mechanically coupled is explained. Software architecture to control the system and the advantages it has to maintain the system is described at a cost of system complexity. The in-house tomographic system was used to characterize engineering, geologic and biological samples.

description: The observed quantization of the Hall conductivity in graphene at high magnetic fields is explained as being due to the dynamically generated spatial modulation of either the electron spin or the density, as decided by the details of Coulomb interaction on the scale of lattice constant. It is predicted that at a large in-plane component of the magnetic field such ordering will be present only at the filling factor |f|=1, and absent otherwise. Other experimental consequences of the theory are outlined.

description: We investigate the transmission and reflection of Bose-condensate excitations in the low energy limit across a potential barrier separating two condensates with different densities. The Bogoliubov excitation in the low energy limit has the incident angle where the perfect transmission occurs. This condition corresponds to the Brewster's law for the electromagnetic wave. The total internal reflection of the Bogoliubov excitation is found to occur at a large incident angle in the low energy limit. The anomalous tunneling named by Kagan et al. [Yu. Kagan et al., Phys. Rev. Lett., 90, 130402 (2003)] can be understood in terms of the impedance matching. In the case of the normal incidence, comparison with the results in Tomonaga-Luttinger liquids is made.

Burnout and compassion in acute mental health wards
Creators: name: Tane, Elizabeth
Publisher: name: Lancaster University
Year: 2019

description: Section one of this doctoral thesis presents a literature review examining the prevalence of burnout in mental health inpatient staff, whilst synthesising relevant factors linked to the development of burnout. Across the 17 papers examined, emotional exhaustion was high whilst depersonalisation and personal accomplishment were average when compared with mental health worker norms. Factors consistently related to burnout were divided into two groups: staff factors and organisational factors. Within staff factors, negative attitudes and poor mental and physical health were related to higher levels of burnout, whilst within organisational factors, a poor ward climate, lack of social support and team working, and exposure to violence were related to higher burnout. The clinical implications and methodological and theoretical limitations were considered. Section two reports the findings of the empirical paper, that qualitatively explored staffs’ conceptualisation of the development, loss and restoration of compassion within acute mental health wards. A total of 11 participants were interviewed, and using grounded theory informed methodology, five theoretical categories were identified: a compassionate stance, the challenges of acute mental health wards, feeling under threat and the negative appraisal system, restoring compassion and the compassionate organisation. This informed a sequential model of the processes underpinning the development, loss and restoration of staff compassion within this environment. The findings highlight the importance of colleague support, knowing and understanding patients and their history, accessing a reflective space and a compassionate organisation in the maintenance and restoration of compassion. The clinical implications arising from the findings are considered. Finally, a critical appraisal of the work is presented, which offers reflections on the process, the influence of epistemology and terminology, adopting a compassionate stance towards the project and directions for future research.

description: Rear-end collision accounts for around 8% of all vehicle crashes in the UK, with the failure to notice or react to a brake light signal being a major contributory cause. Meanwhile traditional incandescent brake light bulbs on vehicles are increasingly being replaced by a profusion of designs featuring LEDs. In this paper, we investigate the efficacy of brake light design using a novel approach to recording subject reaction times in a simulation setting using physical brake light assemblies. The reaction times of 22 subjects were measured for ten pairs of LED and incandescent bulb brake lights. Three events were investigated for each subject, namely the latency of brake light activation to accelerator release (BrakeAcc), the latency of accelerator release to brake pedal depression (AccPdl), and the cumulative time from light activation to brake pedal depression (BrakePdl). To our knowledge, this is the first study in which reaction times have been split into BrakeAcc and AccPdl. Results indicate that the two brake lights containing incandescent bulbs led to significantly slower reaction times compared to the tested eight LED lights. BrakeAcc results also show that experienced subjects were quicker to respond to the activation of brake lights by releasing the accelerator pedal. Interestingly, the analysis also revealed that the type of brake light influenced the AccPdl time, although experienced subjects did not always act quicker than inexperienced subjects. Overall, the study found that different designs of brake light can significantly influence driver response times.

description: The question of whether intelligent life exists elsewhere is one of the fundamental unknowns about our Universe. Over the past decade more than 200 extra-solar planets have been discovered, providing new urgency for addressing this question in these or other planetary systems. Independently of this perspective, new radio observatories for cosmology are currently being constructed with the goal of detecting 21cm emission from cosmic hydrogen in the redshift range 6

title: Identification and optimisation of ligands to target protein-protein interactions: EB1-SxIP proteins
Creators: name: Almeida, TB
Publisher: name: University of Liverpool Repository

description: End binding protein 1 (EB1) is a key element in the complex network of protein-protein interactions at microtubule growing ends which has a fundamental role in microtubule polymerisation. EB1 regulates the microtubule dynamic behaviour, through protein recruitment, and has been associated with several disease states, such as cancer and neuronal diseases. Diverse EB1 binding partners are recognised through a conserved SxIP motif within an intrinsically disordered region enriched with basic, serine and proline residues. Crystal structure of EB1 in complex with a peptide containing the SxIP motif demonstrated that the isoleucine-proline dipeptide is bound into a well‐defined cavity of EB1 that may be suitable for small molecule targeting. The research described herein reports the use of a multidisciplinary approach for the discovery of the first small molecule scaffold to target the EB1 recruiting domain. This approach included virtual screening (structure and ligand based design) and multiparameter compound selection. Solution NMR structures of the C-terminal domain of EB1 in the free form and in complex with the small molecule are also reported. A key finding from these structures is that the hydrophobic binding pocket reported to be essential for recruiting SxIP proteins is not pre-formed but highly dynamic in solution. This brings new insights to the protein recruitment mechanism regulated by EB1 and for the identification of new small molecule inhibitors for the EB1-SxIP protein interactions. The interaction of short length peptides containing the SxIP motif with EB1 was characterised through the use of solution NMR and ITC methods. The contributions for the binding of the SxIP motif and neighbouring residues to EB1 were quantified in terms of binding energy. A structural model shows that the binding pocket of EB1 is largely extended when in complex. This research describes not only the first chemical scaffold that targets EB1, it details important structural features of the interaction of this protein with SxIP containing peptides. This structural information provides fundamental understanding of this interaction that can be exploited in the future to discover higher affinity ligands.

Diagnosis and history
This rather small species is only known from a few localities within the Ulguru Mountains in Tanzania (Table 8). It was described from a male specimen, without any locality and supposedly deposited at NMW but not found there. This type specimen might be considered lost. Shelford (1910) suspected this species was African, which was later confirmed by Princis (1965) after observation of female specimens matching with the succinct original description. Besides its coloration pattern, this species is readily identifiable from its small size, its laterally deflexed pronotum and relatively short tarsi (Fig. 26).
Measurements of adults
Female (n = 2): pronotum length ×width: 4.2–4.5×5.3–5.4, tegmina length: 12.8–13.5, overall length ×width: 15–16.1× 7.5–7.7.
Habitat
The labels read: transitional forest, in humus.
Distribution
This species is only known from Tanzania (Table 8).

description: Using DBI inflation as an example, we demonstrate that the detailed geometry of warped compactification can leave an imprint on the cosmic microwave background (CMB). We compute CMB observables for DBI inflation in a generic class of warped throats and find that the results (such as the sign of the tilt of the scalar perturbations and its running) depend sensitively on the precise shape of the warp factor. In particular, we analyze the warped deformed conifold and find that the results can differ from those of other warped geometries, even when these geometries approximate well the exact metric of the warped deformed conifold.

description: We show that if dark energy evolves in time, its dynamical component could be dominated by a bath of dark radiation. Within current constraints this radiation could have up to $\sim 10^4$ times more energy density than the cosmic microwave background. We demonstrate particular models in which a rolling scalar field generates different forms of dark radiation such as hidden photons, milli-charged particles and even Standard Model neutrinos. We find the leading effect on the late-time cosmological expansion history depends on a single parameter beyond $Λ$CDM, namely the temperature of the dark radiation today. Cosmological observations of this modified expansion rate could provide a striking signature of this scenario. The dark radiation itself could even be directly detectable in laboratory experiments, suggesting a broader experimental program into the nature of dark energy.

description: Land cover is an important variable for climate, hydrology, and ecology studies. With the availability of various high-resolution global land cover (GLC) products, conducting a comprehensive assessment on their accuracy and consistency is important. In this study, we compared the performance of three latest 10-m-resolution GLC products, which include FROMGLC10 in 2017, ESA’s Worldcover10 in 2020, and ESRIGLC10 in 2020, and three latest 30-m-resolution GLC products, which include FROMGLC30 in 2017, GLC_FCS30 in 2020, and Globeland30 in 2020, in China. The consistency of these products was investigated in terms of spatial consistency and area consistency. Though the six GLC products demonstrate similar overall distribution patterns, their detailed spatial distributions are quite different, especially for the three 10-m-resolution products. Evidently, the cropland, forest, grassland, and bareland exhibited high inconsistencies than the other types. The classification accuracy of the six GLC products was also quantitatively assessed based on a visual-interpretation-based reference dataset. FROMGLC10 exhibits the highest overall accuracy of 65.57%, followed by FROMGLC30 (64.96%) and Worldcover10 (62.74%). ESRIGLC10 (49.79%) exhibits the lowest accuracy. The accuracies of shrubland, wetland, and tundra were relatively low. This study provides a valuable reference for selecting appropriate GLC products for potential users.
