description: Human mobility networks can reveal insights into resilience phenomena, such as population response to, impacts on, and recovery from crises. The majority of human mobility network resilience characterizations, however, focus mainly on macroscopic network properties; little is known about variation in measured resilience characteristics (i.e., the extent of impact and recovery duration) across macroscopic, substructure (motif), and microscopic mobility scales. To address this gap, in this study, we examine the human mobility network in eight parishes in Louisiana (USA) impacted by the 2021 Hurricane Ida. We constructed human mobility networks using location-based data and examined three sets of measures: (1) macroscopic measures, such as network density, giant component size, and modularity; (2) substructure measures, such motif distribution; and (3) microscopic mobility measures, such as the radius of gyration and average travel distance. To determine the extent of impact and duration of recovery, for each measure, we established the baseline values and examined the fluctuation of measures during the perturbation caused by Hurricane Ida. The results reveal the variation of impact extent and recovery duration obtained from different sets of measures at different scales. Macroscopic measures, such as giant components, tend to recover more quickly than substructure and microscopic measures. In fact, microscopic measures tend to recover more slowly than measures in other scales. These findings suggest that resilience characteristics in human mobility networks are scale-variant, and thus, a single measure at a particular scale may not be representative of the perturbation impacts and recovery duration in the network as a whole. These results spotlight the need to use measures at different scales to properly characterize resilience in human mobility networks.

Automated learning of performance models for cloud-native applications

Publisher: name: Imperial College London
Year: 2024

description: DevOps is widely used in software development, allowing engineers to release and update software products frequently. It is important to consider system performance to ensure the quality of cloud-native applications. However, working on system performance prediction for microservices and serverless-based applications can be costly and error-prone when models are parameterized on real data. In this thesis, we employ automated learning of performance models from coarse-grained to fine-grained levels. We first focus on accurate model parameterization for microservices. The challenge we tackle is to fit the monitoring data with higher-order moments of the distribution to precisely predict the performance. Next, we focus on automatically generating performance models for serverless applications. The main issue is the information gap between the structural modeling and monitoring granularity, as well as high-level automation. Lastly, we focus on performance diagnosis with code-level tracing strategies to provide inference for internal failures. Even though distributed tracing provides observations at multiple granularities, excessive code instrumentation increases the overheads in terms of computation and storage. To address the first challenge, we propose a service demand distribution estimation method based on coarse-grained inter-departure times, for both single and multiple service classes. Our experiments yield better performance on fitting real traces of microservices compared to the baseline with Exponential distributions. For the gaps in the automatic performance model generation, we propose to build a compact queueing model based on static analysis and fine-grained profiling data. The experiments on serverless workflows deployed on a public cloud achieve accurate prediction, with a mean error under 7.3%. To mitigate the issues in performance diagnosis, we present a methodology combining code-level analysis to devise tracing data collection strategies and relate probe placements aided by novelty detection methods. Our experimental results show a higher recall score of 90% locating single and multiple faults for 15% latency anomalies.
Optimal control and design for space-efficient rainwater harvesting and flood-mitigation systems
Creators: name: Soh, Qiao Yan
Publisher: name: Imperial College London
Year: 2023

description: There is strong consensus that water stresses around the globe are increasing with rapid pace. Climate change is bringing about more extreme and unpredictable weather events, whilst urbanisation has been found to significantly alter the local water cycle which further compounds the impacts of climate change. This thesis investigates future-proofing water management systems in urban areas. It has a specific focus on rainwater harvesting and flood-mitigation systems, as these multi-purpose systems have significant potential in addressing the water challenges expected in the near future. This study examines these issues through employing state-of-the-art computational methods in the development of accessible frameworks for optimising the design and operational policies of water management infrastructure. A high-resolution simulation tool was developed to address the gap in existing simulation strategies in which short-term events, such as flash floods, were not captured. This was used to evaluate the system designs and operational strategies derived using an optimisation tool, also developed as part of this thesis, which was deliberately structured such that optimisation models can be built for any given system. These tools are novel in their scalability and accessibility, which are key contributions towards more effective strategies for designing efficient, multi-purpose water management systems. Evaluated using real-world data from a residential estate in Singapore, the maximum level of improvement was found when the system design and control were optimised simultaneously. Under this framework, a system that is 20\% smaller than the existing configuration was found, which was able to both eliminate overflow events from historical rainfall days and increase the average harvested water yield by 176\%. This corresponds to a 48.6\% increase in the balance of savings, demonstrating substantial improvements to the system's demand fulfilment capabilities. Hence, optimisation-based design strategies can significantly increase the effectiveness of multi-purpose systems, which are key towards a sustainable water future.
Fast repetition rate fluorometry (FRRF) measuring phytoplankton productivity: A case study at the entrance to the Gulf of Finland, Baltic Sea

Year: 2004

description: The fast repetition rate (FRR) fluorometry, based on variable fluorescence of chlorophyll a, has been introduced as a potential tool to evaluate the primary productivity (PP) in aquatic systems. I measured PP in situ with both the 14C and the FRR techniques at the entrance to the Gulf of Finland, Baltic sea, and noticed that the relation between the 14C-based (Pb) and the FRR-based (Pf) estimates of PP was non-linear. This discrepancy between Pf measuring the rate of linear photosynthetic electron flow, and Pb measuring the rate of C fixation should be resolved before the PP can be reasonably estimated with the FRR technique. The deviation from linearity took place at irradiances above 200 µmol quanta m–2 s–1, since Pb reached light-saturation at lower irradiances than did Pf. Within the regression fits, the daily variability in Pb explained at least 85% of the daily variability in Pf (a total of four days, n = 11 on each day). The period of time over which PP was determined was substantially different for the two approaches; over 2 h for Pb, and approximately 10 s for Pf. Consequently, most of the deviation around the resulting fits was caused by the sensitivity of the FRR technique to the momentary incident irradiance at the time of the measurement. The FRR-based photosynthetic efficiency of phytoplankton in the upper parts of the water column could be divided into three layers: reduced levels in the near-surface layer due to inhibiting effect of supraoptimal irradiance, the layer beneath this having the highest levels, and the deepest layer inhabited by a senescent algal population characterized by lowered levels.

description: This paper introduces the first public large-scale, long-span dataset with sea turtle photographs captured in the wild -- \href{https://www.kaggle.com/datasets/wildlifedatasets/seaturtleid2022}{SeaTurtleID2022}. The dataset contains 8729 photographs of 438 unique individuals collected within 13 years, making it the longest-spanned dataset for animal re-identification. All photographs include various annotations, e.g., identity, encounter timestamp, and body parts segmentation masks. Instead of standard "random" splits, the dataset allows for two realistic and ecologically motivated splits: (i) a \textit{time-aware closed-set} with training, validation, and test data from different days/years, and (ii) a \textit{time-aware open-set} with new unknown individuals in test and validation sets. We show that time-aware splits are essential for benchmarking re-identification methods, as random splits lead to performance overestimation. Furthermore, a baseline instance segmentation and re-identification performance over various body parts is provided. Finally, an end-to-end system for sea turtle re-identification is proposed and evaluated. The proposed system based on Hybrid Task Cascade for head instance segmentation and ArcFace-trained feature-extractor achieved an accuracy of 86.8\%.

A novel energy reconstruction method for the MAGIC stereoscopic observation

description: We present a new gamma ray energy reconstruction method based on Random Forest to be commonly used for the data analysis of the MAGIC Telescopes, a system of two Imaging Atmospheric Cherenkov Telescopes.
 The energy resolution with the new energy reconstruction improves compared to the one obtained with the LUTs method. For standard observations i.e. dark conditions with pointing zenith (Zd) less than 35 deg for a point-like source, the energy resolution goes from $\sim 20\%$ at 100 GeV to $\sim 10\%$ at a few TeV.
 In addition, the new method suppresses the outlier population in the energy error distribution, which is thus better described by a Gaussian distribution. The new energy reconstruction method enhances the reliability especially for the sources with steep spectra, in higher energies and/or in observations at higher Zd pointings.
 We validate the new method in different ways and demonstrate some cases of its remarkable benefit in spectral analysis with simulated observation data.

description: The self-configuring nnU-Net has achieved leading performance in a large range of medical image segmentation challenges. It is widely considered as the model of choice and a strong baseline for medical image segmentation. However, despite its extraordinary performance, nnU-Net does not supply a measure of uncertainty to indicate its possible failure. This can be problematic for large-scale image segmentation applications, where data are heterogeneous and nnU-Net may fail without notice. In this work, we introduce a novel method to estimate nnU-Net uncertainty for medical image segmentation. We propose a highly effective scheme for posterior sampling of weight space for Bayesian uncertainty estimation. Different from previous baseline methods such as Monte Carlo Dropout and mean-field Bayesian Neural Networks, our proposed method does not require a variational architecture and keeps the original nnU-Net architecture intact, thereby preserving its excellent performance and ease of use. Additionally, we boost the segmentation performance over the original nnU-Net via marginalizing multi-modal posterior models. We applied our method on the public ACDC and M&M datasets of cardiac MRI and demonstrated improved uncertainty estimation over a range of baseline methods. The proposed method further strengthens nnU-Net for medical image segmentation in terms of both segmentation accuracy and quality control.
Distribution of heavy metals in recent sediments in the Archipelago Sea of southwestern Finland
Creators: name: Müller, A.
Publisher: name: Boreal Environment Research Publishing Board
Year: 1999

description: The distributions of organic carbon, sulphur, phosphate, and heavy metals (Ni, Co, Cu, Zn, Pb, Cd, Mn, Fe) were analyzed in marine surface sediments in the Archipelago Sea of southwestern Finland. Variations in heavy metal contents are caused mainly by physical not chemical processes. Lateral transport processes of particulate matter, including organic matter, strongly influence the distribution pattern of heavy metals in the study area. In addition, variable environmental conditions between stations contribute to differences in heavy metal contents. In the harbor, close to the mouth of the Aurajoki, there is a relatively high potential for the binding of heavy metals by oxides/hydroxides. In contrast, sulphide precipitations of heavy metals in the sediments may become relatively more important with increasing water depth, i.e. towards the outer Archipelago Sea. For chromium, aluminium, titanium and vanadium detrital binding was considered to be dominant.
Sea migration patterns in the Atlantic salmon: a comparative study of two stocks and their hybrids

Year: 1999

description: The sea migration patterns of the Atlantic salmon in the Baltic Sea was examined in a crossing and transplantation experiments. Two genetically different salmon stocks originating from rivers Neva and Iijoki and their hybrids were released as smolts (6 561, 485 and 993 smolts, respectively) into the estuary of the Kymijoki, in the Gulf of Finland. The spatial and temporal marine distributions of the experimental groups were analysed from tag recovery data received during 31/2 years (42 months) after release. The recovery rate was 6.5%–17.5%. Multi-way contingency analysis showed that the spatial distributions of the stocks differed in the sea. The feeding migration distance of the hybrids was longer than that of the parental Neva stock, and the male line affected the spatial marine distribution of the hybrids more than did the female line. Genetically different parental stocks showed no significant difference in migratory behaviour in this experiment. No differences were recorded in the temporal distributions of the stocks in the sea. The observed differences confirm that the sea migration pattern is a stock-specific, inherited trait. The longer migration pattern of hybrid stocks than that of parental stocks may be due to coadaptive gene combinations that break down in crossing or to a high phenotypic variation in parents within the stocks.

description: We construct an effective field theory describing the collective Tkachenko oscillation mode of a vortex lattice in a two-dimensional rotating Bose-Einstein condensate in the long-wavelength regime. The theory has the form of a noncommutative field theory of a Nambu-Goldstone boson, which exhibits a noncommutative version of dipole symmetry. From the effective field theory, we show that, at zero temperature, the decay width $Γ$ of the Tkachenko mode scales with its energy $E$ as $Γ\sim E^3$ in the low-energy limit. We also discuss the width of the Tkachenko mode at a small temperature.

Acid deposition trends at the Finnish Integrated Monitoring catchments in relation to emission reductions

Publisher: name: Boreal Environment Research Publishing Board
Year: 1998

description: The effects of transboundary air pollutants on deposition levels and precipitation concentrations have been monitored within the UN/ECE Integrated Monitoring Programme since 1988 at four Finnish background stations. A monotonic decreasing trend was detected for the concentration and deposition of sulphate, nitrate, ammonium and potassium at the southern stations. Further to the north, fewer compounds showed a significant reduction. For sulphur, model calculations with the operational deposition model DAIQUIRI also indicate a clear decrease in deposition. At the southern stations this reflected rather well the reduction of sulphur emissions in Finland and elsewhere in Europe. In the northern part of the country, where the distance to the major emission sources is longer and transport is more affected by meteorological parameters, wind direction especially, the annual amounts of sulphur deposition varied more independently of the changes in emission levels. The proportion of domestic oxidised nitrogen and total ammonium deposition decreased on moving northwards. The downward trend for nitrogen compounds throughout the country seems to be due to international emission reductions.

description: This paper explores the comparative dynamics of self-mutilation among young, contemporary, female self-cutters, and the holy stigmatics of the Middle Ages. It addresses the types of personalities that engage in self-mutilation and how some manipulate their self-inflicted pain into a method for healing and empowerment. The similarities between teenage cutters and female stigmatics are striking in their mutual psychoanalytical need for self-alteration as a means of escaping their own disassociative identities; and offers evidence of how their mutual bricolage of pain, imagining, languaging, and subsequent self-mutilation often provide a transformation from bodies under siege to a resemblance of health and transformation.

description: The non-Hermitian skin effect dramatically reshapes the energy bands of non-Hermitian systems, meaning that the usual Bloch band theory is fundamentally inadequate as their characterization. The non-Bloch band theory, in which the concept of Brillouin zone is generalized, has been widely applied to investigate non-Hermitian systems in one spatial dimension. However, its generalization to higher dimensions has been challenging. Here, we develop a formulation of the non-Hermitian skin effect and non-Bloch band theory in arbitrary spatial dimensions, which is based on a natural geometrical object known as the amoeba. Our theory provides a general framework for studying non-Hermitian bands beyond one dimension. Key quantities of non-Hermitian bands, including the energy spectrum, eigenstates profiles, and the generalized Brillouin zone, can be efficiently obtained from this approach.

description: Trace gases (SO2, NOx, O3) and aerosol particles alongside with meteorological parameters have been measured continuously since 1992 in a remote Arctic station in Värriö, Finnish Lapland. In this background region there are practically no local sources of pollution. The goal of this study was to investigate the transport of gaseous pollutants and aerosol particles to a remote area. The seasonal, diurnal and long-term behaviour of trace gases and aerosol particles is presented as well as their correlation with each other and with local wind direction. A slightly diminishing trend was observed for low summertime ozone (O3) concentrations from 1995 to 2001. No distinct long-term trends for other species were noted. The monthly-medium concentrations were highest for SO2 and NOx in the winter, for ozone in the spring and for aerosol particles in the summer. The cleanest air seemed to arrive with northwesterly local winds, whereas the most polluted air was associated with easterly local winds and occurred as short episodes.

description: Quantum simulation advantage over classical memory limitations would allow compact quantum circuits to yield insight into intractable quantum many-body problems, but the interrelated obstacles of large circuit depth in quantum time evolution and noise seem to rule out unbiased quantum simulation in the near term. We prove that classical post-processing, i.e., long-time filtering of an offline time series, exponentially improves the circuit depth needed for quantum time evolution. We apply the filtering method to the construction of a hybrid quantum-classical algorithm to estimate energy gap, an important observable not governed by the variational theorem. We demonstrate, within an operating range of filtering, the success of the algorithm in proof-of-concept simulation for finite-size scaling of a minimal spin model. Our findings set the stage for unbiased quantum simulation to offer memory advantage in the near term.

description: Η παρούσα εργασία εξετάζει την επίδραση του μακροοικονομικού περιβάλλοντος στις επιδόσεις των ευρωπαϊκών ενεργειακών εταιρειών, ζήτημα υψηλής σημασίας λόγω της αστάθειας που χαρακτηρίζει τον τομέα. Με σκοπό την κατανόηση του τρόπου με τον οποίο οι ενεργειακές επιχειρήσεις αντιδρούν στις διακυμάνσεις του μακροοικονομικού περιβάλλοντος, αναλύεται η επίδραση πέντε μεγάλων παγκόσμιων γεγονότων στις μετοχές εταιρειών του ενεργειακού κλάδου, χρησιμοποιώντας τη μέθοδο Ανάλυσης Γεγονότων. Συγκεκριμένα, εξετάζονται γεγονότα όπως η πανδημία COVID-19, η ρωσική εισβολή στην Ουκρανία και το σαμποτάζ των αγωγών Nord Stream, καταδεικνύοντας πως οι γεωπολιτικές κρίσεις είχαν αρκετά σημαντική επίδραση στις μετοχές, με τη ρωσική εισβολή και το σαμποτάζ να έχουν τις υψηλότερες θετικές επιπτώσεις στις ενεργειακές εταιρείες, αντίθετα η πανδημία οδήγησε σε μεγαλύτερες αρνητικές επιπτώσεις. Επιπλέον, για τη διερεύνηση της αλληλεπίδρασης μεταξύ τιμών ενεργειακών προϊόντων και απόδοσης των μετοχών, εφαρμόζεται η μέθοδος Διανυσματικής Αυτοπαλινδρόμησης (VAR), αποκαλύπτοντας ότι οι τιμές του πετρελαίου έχουν μακροχρόνια επίδραση στις ενεργειακές μετοχές, σε αντίθεση με άλλες πηγές ενέργειας που επηρεάζουν πιο βραχυπρόθεσμα. Στη συνέχεια, για την εξέταση του τι προσδίδει σε αυτές τις εταιρείες ανταγωνιστικό πλεονέκτημα σε ένα τόσο πολύπλοκο μακροοικονομικό περιβάλλον, μέσω πολυκριτήριας ανάλυσης ELECTRE III, αξιολογούνται τα χαρακτηριστικά που παρέχουν ανταγωνιστικό πλεονέκτημα στις ενεργειακές εταιρείες, αποδεικνύοντας ότι οι εταιρείες που ενσωματώνουν κριτήρια ESG απολαμβάνουν ισχυρότερη ανθεκτικότητα στις κρίσεις, ιδιαίτερα σε περιόδους μεγάλης αστάθειας όπως αυτή της πανδημίας. Συνολικά, τα ευρήματα της μελέτης υπογραμμίζουν την ανάγκη διαφοροποίησης των ενεργειακών πηγών και την υιοθέτηση πρακτικών ESG ως βασικές στρατηγικές για την ενίσχυση της ανταγωνιστικότητας και βιωσιμότητας των ευρωπαϊκών ενεργειακών εταιρειών σε ένα ασταθές μακροοικονομικό περιβάλλον.

description: Considering the profound transformation affecting pathology practice, we aimed to develop a scalable artificial intelligence (AI) system to diagnose colorectal cancer from whole-slide images (WSI). For this, we propose a deep learning (DL) system that learns from weak labels, a sampling strategy that reduces the number of training samples by a factor of six without compromising performance, an approach to leverage a small subset of fully annotated samples, and a prototype with explainable predictions, active learning features and parallelisation. Noting some problems in the literature, this study is conducted with one of the largest WSI colorectal samples dataset with approximately 10,500 WSIs. Of these samples, 900 are testing samples. Furthermore, the robustness of the proposed method is assessed with two additional external datasets (TCGA and PAIP) and a dataset of samples collected directly from the proposed prototype. Our proposed method predicts, for the patch-based tiles, a class based on the severity of the dysplasia and uses that information to classify the whole slide. It is trained with an interpretable mixed-supervision scheme to leverage the domain knowledge introduced by pathologists through spatial annotations. The mixed-supervision scheme allowed for an intelligent sampling strategy effectively evaluated in several different scenarios without compromising the performance. On the internal dataset, the method shows an accuracy of 93.44% and a sensitivity between positive (low-grade and high-grade dysplasia) and non-neoplastic samples of 0.996. On the external test samples varied with TCGA being the most challenging dataset with an overall accuracy of 84.91% and a sensitivity of 0.996.

description: Address matching is an important task for many businesses especially delivery and take out companies which help them to take out a certain address from their data warehouse. Existing solution uses similarity of strings, and edit distance algorithms to find out the similar addresses from the address database, but these algorithms could not work effectively with redundant, unstructured, or incomplete address data. This paper discuss semantic Address matching technique, by which we can find out a particular address from a list of possible addresses. We have also reviewed existing practices and their shortcoming. Semantic address matching is an essentially NLP task in the field of deep learning. Through this technique We have the ability to triumph the drawbacks of existing methods like redundant or abbreviated data problems. The solution uses the OCR on invoices to extract the address and create the data pool of addresses. Then this data is fed to the algorithm BM-25 for scoring the best matching entries. Then to observe the best result, this will pass through BERT for giving the best possible result from the similar queries. Our investigation exhibits that our methodology enormously improves both accuracy and review of cutting-edge technology existing techniques.

description: Magnetic nanoparticles of high magnetic susceptibility, such as magnetite (Fe3O4), have been used for wireless heating of adhesives and composites through the magnetic hysteresis loss mechanism, but the high concentrations of nanoparticles needed to meet heating performance targets can degrade mechanical properties. Herein, we present an in-situ aligning method to enhance the heating efficiency of magnetite nanoparticles in a nylon thermoplastic matrix without adversely affecting its mechanical strength. A composite adhesive was made by dispersing Fe3O4 nanoparticles in a nylon matrix followed by hot melting. Experimental results show that by subjecting the adhesive to an alternating magnetic field during the hot-melt process, its heating rate can be improved by 200% compared to that without applying the magnetic field. The improvement in the heating performance has been identified to stem from the alignment of the ease axis of the magnetic nanoparticles. This in-situ aligning technique enables better induction heating performance with the same amount of Fe3O4 nanoparticles, avoiding the agglomeration problem of high nanoparticle concentrations. Moreover, this technique makes it possible to develop high-performance self-heating thermoplastic adhesive for reversible bonding and self-healing solution with a wide range of applications, such as bonding and debonding of composites, temporary attachment of systems, and recyclable bonded structures.

description: The effects of forest cuttings on the level of the groundwater table and the quality of groundwater in large aquifers in Finland were studied by interpreting the long-term data from three groundwater monitoring stations together with information about the forest management history. Groundwater nitrate concentrations increased after clear-cuttings and thinnings for several years after the operations. However, the nitrate concentrations remained low (< 2 mg l–1) even after the treatments. None of the changes in the groundwater level or in the other studied variables (electrical conductivity, alkalinity, pH, ammonium, chloride, sulphate, sodium, potassium, calcium and magnesium) could be attributed to the forestry operations.

description: The trace gas and aerosol concentrations as well as meteorological data (radiation, temperature, humidity) measured in Hyytiälä and Värriö, southern and northern Finland, respectively, were investigated with air mass analyses. The back trajectories of air masses arriving to the sites on the 925-hPa pressure level were calculated 96 hours backwards in time. Two trajectories per day, arriving at 00 UTC and 12 UTC, were computed. The studied time period covered December 1997 to August 1998, November 1998 to July 1999, and September 1999. The arriving air masses were divided into five sectors according to their origin: I = North–West (Arctic Ocean), II = North–East (Northern Russia, Kola Peninsula), III = South–East (Southern Russia, St. Petersburg), IV = South–West (Central Europe, Great Britain), and V Local, circulating air masses. The climatology of various properties of air masses originating from different sectors was studied. The analysis showed differences between typically clean (sectors I and II) and polluted (sectors III and IV) air masses. In air masses from sectors III and IV, the NOx concentrations were high during all seasons, but the O3 concentrations were high during the spring and summer seasons and low in winter. The highest SO2 concentrations arrived from sector III. In Värriö also the air from sector II was accompanied with higher SO2 concentrations and some very high peaks were observed in winter when air masses passed through the industrial area of Kola Peninsula. Nucleation events typically occurred in clean air masses and accumulation mode concentrations were higher in polluted air masses. Although there were some differences between Hyytiälä and Värriö, the overall behaviour was similar at both sites.

description: We have dealt with the twist-4 T-even transverse momentum-dependent parton distributions (TMDs) for the case of proton in the light-front quark-diquark model (LFQDM). By decoding the unintegrated quark-quark correlator for the semi-inclusive deep inelastic scattering (SIDIS), we have specifically obtained the overlap form for the unpolarized \bigg($f_{3}^ν(x, {\bf p_\perp^2})$\bigg), longitudinally polarized \bigg($ g_{3L}^ν(x, {\bf p_\perp^2}),~h_{3L}^{\perpν}(x, {\bf p_\perp^2})$\bigg) and transversely polarized \bigg( ${g}^{ν}_{3T}(x, {\bf p_\perp^2}),~{h}^{ν}_{3T}(x, {\bf p_\perp^2})$ and ${h}^{ν\perp}_{3T}(x, {\bf p_\perp^2})$\bigg) proton TMDs. We have provided the explicit expressions for both the cases of the diquark being a scalar or a vector. Average transverse momenta and the average square transverse momenta for the TMDs have been calculated and the results have been tabulated with corresponding leading twist TMDs. In addition, the value of average transverse momentum and average square transverse momentum for TMD ${f}^{ν}_3(x, {\bf p_\perp^2})$ has been compared with the available light-front constituent quark model (LFCQM) results. From TMDs, we have also obtained and discussed the transverse momentum-dependent parton distribution functions (TMDPDFs). The model relations of the twist-4 T-even TMDs with the available leading twist T-even TMDs have also been obtained.

description: Rhizosphere wettability decreases upon severe drying leading to periods of prolonged low water content around roots after precipitation or irrigation. These observations were explained by the temporal hydrophobic character of mucilage, while structural alterations of the pore space caused by mucilage, such as pore clogging, remained mostly unexplored. In this study, time-series neutron radiography and a pore network model were used to assess the impact of pore geometry and wettability on water flow following the addition of mucilage in a sand substrate. To do so, we monitored the capillary rise of ethanol and water separately for mucilage contents, ranging from 0.0 to 2.0 mg g−1. A pore network model was developed to analyze the impact of alterations in pore geometry and wettability. Results are compared with analytical solutions of the Lucas-Washburn equation. Rewetting dynamics were explained by a combination of a decrease in effective pore throat size and a global decrease in wettability. The local distribution of wettability, however, appeared of minor importance as dynamics of water imbibition could be matched by a uniform effective contact angle. For 0.1 mg g−1 mucilage content increased wettability was predicted for both approaches: the analytical solution and the pore network model fit. At larger contents, a decrease in wettability occurred which was accompanied by a decrease in derived effective pore and pore throat size. On a minute scale, rewetting appeared to steadily progress at all mucilage contents with accelerated rewetting observed at 0.6 mg g−1 likely related to an increased wetting front length. This study highlights the importance of mucilage on pore geometry in combination with wettability modifications in the rhizosphere. Aside from rhizosphere rewetting, the presented approach provides an opportunity to investigate further wettability-related processes in other soil environments on various spatial scales.

description: The subject matter of this work is a 1D quantum spin - [Formula presented] chain associated with the inhomogeneous six-vertex model possessing an additional Zr symmetry. The model is studied in a certain parametric domain, where it is critical. Within the ODE/IQFT approach, a class of ordinary differential equations and a quantization condition are proposed which describe the scaling limit of the system. Some remarkable features of the CFT underlying the critical behaviour are observed. Among them is an infinite degeneracy of the conformal primary states and the presence of a continuous component in the spectrum in the case of even r.
