description: Conversation Analysis was used to explore how teachers, personal care assistants, and students organized inclusive multiparty classroom interaction when one of the students in the classroom used an eye-gaze accessed speech-generating device (SGD). Scaffolding and collaborative practices that created a response space for the construction of the eye-gaze accessed SGD-mediated turn were identified and analyzed. The participants were two adolescent students with severe cerebral palsy and intellectual disability who relied on eye-gaze accessed SGDs, and their teachers, personal care assistants, and classmates with intellectual disabilities. The data consisted of 2 hr and 40 min of video recordings collected in the participants’ classrooms. Three practices were identified (a) the practice of explicit turn allocation organization and the use of display questions, (b) the practice of locally contingent on-screen scaffolding activities, and (c) the practice of dealing with turn competition by classmates. Teacher and assistant practices differed with regard to the student’s access to the vocabulary relevant to answering the teacher’s question. The practices were found to create a response space for students using SGDs accessed via eye gaze, thereby ensuring their educational inclusion in the classroom.

description: Difficulties with communication have a profound impact on the lives of individuals with Rett syndrome and their caregivers. Globally, many families report difficulty accessing appropriate and timely information and services from professionals with expertise in augmentative and alternative communication (AAC) as it pertains to Rett syndrome. To address this need, international consensus-based guidelines for managing the communication of individuals with Rett syndrome were developed by combining available evidence and lived experience with expert opinion. A two-phase Delphi survey was built on statements and recommendations extracted from a review of over 300 pieces of literature combined with survey responses from communication professionals and caregivers. All statements that reached a pre-determined threshold of ≥70% agreement were incorporated into guidelines that consist of 268 statements and recommendations relating to (a) rights of the individual; (b) beliefs and attitudes of communication partners; (c) professional knowledge and team work; (d) strategies to optimize engagement; (e) assessment; and (f) intervention (targets and goals, techniques), including the use of AAC. To date, this project is the largest of its kind, with 650 participants from 43 countries contributing to development of consensus-based guidelines for Rett syndrome.
Rotating Spiral Waves with Phase-Randomized Core in Non-locally Coupled Oscillators

description: Rotating spiral waves with a central core composed of phase-randomized oscillators can arise in reaction-diffusion systems if some of the chemical components involved are diffusion-free. This peculiar phenomenon is demonstrated for a paradigmatic three-component reaction-diffusion model. The origin of this anomalous spiral dynamics is the effective non-locality in coupling, whose effect is stronger for weaker coupling. There exists a critical coupling strength which is estimated from a simple argument. Detailed mathematical and numerical analyses are carried out in the extreme case of weak coupling for which the phase reduction method is applicable. Under the assumption that the mean field pattern keeps to rotate steadily as a result of a statistical cancellation of the incoherence, we derive a functional self-consistency equation to be satisfied by this space-time dependent quantity. Its solution and the resulting effective frequencies of the individual oscillators are found to agree excellently with the numerical simulation.

A scheme of measurement of quantum-vacuum geometric phases in the noncoplanar fibre system

description: We study the quantum-vacuum geometric phases resulting from the vacuum fluctuation of photon fields in Tomita-Chiao-Wu noncoplanar curved fibre system, and suggest a scheme to test the potential existence of such vacuum effect. Since the signs of the quantum-vacuum geometric phases of left- and right- handed (LRH) circularly polarized light are just opposite, the total geometric phases at vacuum level is inescapably absent in the fibre experiments performed previously by other authors. By using the present approach where the fibre made of gyroelectric media is employed, the quantum-vacuum geometric phases of LRH light cannot be exactly cancelled, and may therefore be achieved test experimentally.

Convention on the Legal Status of the Caspian Sea
Game theory

description: Following the collapse of Soviet Union in 1991, a new global security risk appeared — the onset of contentious relations around the Caspian Sea. Conflicting interests among littoral states resulted in a decades long dispute over ownership of regional resources. Unanimous cooperation in the area was not realized until 2018, when Azerbaijan, Kazakhstan, Iran, Russia, and Turkmenistan signed a convention on the status of the contested waterbody. Prior to this resolution, game theorists recommended a host of methods to divide Caspian resource wealth. This report considers preconditions leading to the agreement in order to weigh proposed game theoretic solutions against outcomes following the signing. It examines the predicted optimal cooperative and non-cooperative division strategies for each country and the entire region. In this paper, game theoretic proposals are compared with guarantees granted to riparian states under the convention in order to characterize both the effectiveness of algorithmic approaches to real, complex relationships and the consequences derived from the 2018 agreement on the game.

description: The influence of electron-electron Coulomb repulsion on nonsequential double ionization of rare-gas atoms is investigated. Several variants of the quantum-mechanical transition amplitude are evaluated that differ by the form of the inelastic electron-ion rescattering and whether or not Coulomb repulsion between the two electrons in the final state is included. For high laser intensity, an entirely classical model is formulated that simulates the rescattering scenario.

description: By the Robertson–Price identity (RPI), the change in a quantitative trait due to selection is equal to the trait's covariance with relative fitness. In this study, we applied the identity to long-term data on superb fairy-wrens Malurus cyaneus, to estimate phenotypic and genetic change due to juvenile viability selection. Mortality in the four-week period between fledging and independence was 40%, and heavier nestlings were more likely to survive, but why? There was additive genetic variance for both nestling mass and survival, and a positive phenotypic covariance between the traits, but no evidence of additive genetic covariance. Comparing standardized gradients, the phenotypic selection gradient was positive, βP = 0.108 (0.036, 0.187 95% CI), whereas the genetic gradient was not different from zero, βA = −0.025 (−0.19, 0.107 95% CI). This suggests that factors other than nestling mass were the cause of variation in survival. In particular, there were temporal correlations between mass and survival both within and between years. We suggest that use of the Price equation to describe the cross-generational change in the wild may be challenging, but a more modest aim of estimating its first term, the RPI, to assess within-generation change can provide valuable insights into the processes shaping phenotypic diversity in natural populations.This article is part of the theme issue ‘50 years of the Price equation’.
Oxidation and mechanical behaviour of reaction-bonded silicon carbide-boron carbide and the corrosion of dip-coated rare-earth silicate environmental barrier coatings under CMAS exposure
Creators: name: Abdelhadi, Kareem
Publisher: name: Imperial College London
Year: 2024

description: The oxidation of reaction-bonded SiC–B4C (RBSBC) in air was studied at 1250–1350°C for 5–96 hours. SEM showed a 3–5 μm uniform oxide layer after 48 h. TEM, Raman, and SIMS analyses revealed that the oxidation of 7 wt% B4C with (SiC+ Si)/B4C ratio of ⁓13 produced an amorphous Si-rich borosilicate layer. Oxidation followed a parabolic rate controlled by ionic oxygen transport, and with an activation energy of 353 kJ mol–1. RBSBC with 7 wt% B4C offers a cost-effective and lower-density alternative to SiC for oxidation-resistant applications. The CMAS corrosion of three different (RE)-based (Yb, Lu and Er) EBCs was studied at 1300 °C for 1–48 h. The EBCs were applied on the RBSBC substrate using dip coating. At the CMAS–EBC interface, Yb and Lu formed protective garnet, while Er-silicate formed non-protective stoichiometric apatite. SEM and EDS showed that Yb and Lu had lower diffusion coefficients compared to Er-silicate, indicating higher CMAS resistance. XPS revealed that the Ca–Yb–Si oxyapatite phase was formed by substitutional diffusion that is controlled by vacancy formation in the RE2O3 lattice. Higher Ca content in the structure suppresses vacancy formation, which decreases Ca diffusion through the coat, thereby enhancing CMAS resistance. DIC using high-speed camera was used to study the fracture behaviour of RBSBC. RBSBC failed transgranularly, where randomly-dispersed coarse B4C grains deflects the crack path. R-curve for the stress intensity at the crack tip K_I was determined experimentally using the displacement values at the crack tip using virtual extensometers on the DIC images, and using the LEFM SENB theory based on the fracture load and crack length. The experimental K_I has higher values than the quasistatic because it reflects the actual conditions at the crack tip. Increasing B4C content enhances crack resistance compared to SiC ceramics.
A combinatorial algorithm for computing the rank of a generic partitioned matrix with $2 \times 2$ submatrices

description: In this paper, we consider the problem of computing the rank of a block-structured symbolic matrix (a generic partitioned matrix) $A = (A_{αβ} x_{αβ})$, where $A_{αβ}$ is a $2 \times 2$ matrix over a field $\mathbf{F}$ and $x_{αβ}$ is an indeterminate for $α= 1,2,\dots, μ$ and $β= 1,2, \dots, ν$. This problem can be viewed as an algebraic generalization of the bipartite matching problem and was considered by Iwata and Murota (1995). Recent interests in this problem lie in the connection with non-commutative Edmonds' problem by Ivanyos, Qiao, and Subrahamanyam (2018) and Garg, Gurvits, Oliveiva, and Wigderson (2019), where a result by Iwata and Murota implicitly states that the rank and non-commutative rank (nc-rank) are the same for this class of symbolic matrices. The main result of this paper is a simple and combinatorial $O((μν)^2 \min \{ μ, ν\})$-time algorithm for computing the symbolic rank of a $(2 \times 2)$-type generic partitioned matrix of size $2μ\times 2ν$. Our algorithm is inspired by the Wong sequence algorithm by Ivanyos, Qiao, and Subrahamanyam for the nc-rank of a general symbolic matrix, and requires no blow-up operation, no field extension, and no additional care for bounding the bit-size. Moreover it naturally provides a maximum rank completion of $A$ for an arbitrary field $\mathbf{F}$.

Carbon depletion observed inside T Tauri inner rims: Formation of icy, kilometer size planetesimals by 1 Myr

description: The carbon content of protoplanetary disks is an important parameter to characterize planets formed at different disk radii. There is some evidence from far-infrared and submillimeter observations that gas in the outer disk is depleted in carbon, with a corresponding enhancement of carbon-rich ices at the disk midplane. Observations of the carbon content inside of the inner sublimation rim could confirm how much carbon remains locked in kilometer size bodies in the disk. Using near-infrared spectra, I self-consistently determine the stellar, extinction, veiling, and accretion properties of the 26 stars in my sample. From these values, I extract the inner disk excess of the target stars and identify a series of C^0 recombination lines in 18 of these disks and use the CHIANTI atomic line database with an optically thin slab model to constrain the average n_e, T_e, and n_C for these lines in the five disks with a complete set of lines. By comparing these values with other slab models of the inner disk using the Cloudy photoionization code, I also constrain n_H and the carbon abundance, X_C, and hence the amount of carbon `missing' from the slab. The inner disks are extremely dense (n_H~10^{16} cm^{-3}), warm (T_e~4500 K), and moderately ionized (logX_e~3.3). Three of the five modeled disks show robust carbon depletion <=42 relative to the solar value. I discuss multiple ways in which the `missing' carbon could be locked out of the accreting gas. Given the high-density inner disk gas, evidence for radial drift, and lack of obvious gaps in these three systems, their carbon depletion is most consistent with the `missing' carbon being sequestered in kilometer size bodies. For DR Tau, nitrogen and silicon are also depleted by factors of 45 and 4, respectively, suggesting that the kilometer size bodies into which the grains are locked were formed beyond the N_2 snowline.

Kidney transplantation in older people: impact of frailty on outcomes
Creators: name: Thind, Amarpreet
Publisher: name: Imperial College London
Year: 2023

description: Kidney transplantation (KT) in older people has increased, however older people with kidney disease are vulnerable to frailty and cognitive impairment, which impacts on KT outcomes. In this cohort quality of life (QoL) changes from KT are a greater consideration than survival. Achieving a better understanding of waitlist (WL) and KT experiences, and variation with frailty is therefore crucial to guiding KT discussions and decision-making. This thesis presents work conducted in the Kidney Transplantation in Older People (KTOP): impact of frailty on outcomes study. KTOP was a prospective, single-centre, longitudinal study where older people (aged ³60) on the WL were recruited. Questionnaires assessing frailty, cognition, QoL and patient experience were completed, alongside clinical event and WL activity data collection. Two hundred and ten participants were recruited, 118 of whom were transplanted. At recruitment 37.4% had cognitive impairment, 17.2% were frail, and 19.4% were vulnerable to frailty. On the WL most participants maintained the same frailty status, whilst following KT frailty initially declined before slowly recovering. A trend towards poorer WL and KT clinical outcomes in vulnerable/frail participants was observed, including more major infection events and longer suspension from the WL, and more delayed graft function following KT. Throughout poorer QoL and patient experiences were reported as identified frailty status worsened. On the WL and following KT not frail participants reported stability in their experiences, whilst vulnerable/frail participants reported fluctuating experiences. All recipients experienced a mental QoL decline following KT, but improved treatment satisfaction and illness intrusion. A qualitative study was established to explore the lived experiences in vulnerable/frail participants further. These findings provide a holistic description of KT in older people and demonstrate that frailty assessment is crucial to improving older peoples’ care. Utilising this information enables tailored counselling, decision-making, expectation management, and support for older people to be achieved.

Development of a novel metal-binding lipid as a new building block for artificial cells
Creators: name: Sachet-Fernandez, Gabriela
Publisher: name: Imperial College London
Year: 2024

description: Bottom-up synthetic biology aims at building structures and functions of living cells from non-living building blocks by leveraging tools from biology, chemistry, and materials science. The field has progressed from recreating simple biological functions to integrating complex systems that combine both biological and synthetic functions. For this reason, there is a pressing need to develop new tools to functionalise artificial cells to achieve higher levels of complexity. One approach to functionalise artificial cells is through their membranes, particularly through the incorporation of functional phospholipids in the membrane. Thus, there is a need to synthesise artificial lipids with functional headgroups to enable their incorporation into the membrane of vesicles. In this research, a phosphatidyl-histidinol lipid carrying an imidazole moiety was synthesised as a tool for reversibly binding his-tagged compounds to the membrane of vesicles and facilitating vesicle-vesicle interactions. The lipid was synthesised by enzyme-assisted synthesis using phospholipase D, wherein the headgroup of a phospholipid was transphosphatidylated with L-histidinol. We validated the lipid-binding functionality with metal ions, both in a coated system and in a vesicular system. For proof of concept, his-mEGFP was utilized. Additionally, the lipid exhibited catalytic properties attributed to its imidazole moiety, with a metal dependency as well as a lipid presentation dependency. Unexpectedly, the incorporation of PtdHisOH into a vesicular system promoted membrane asymmetry with the synthetic lipid being predominantly located in the outer leaflet of the bilayer. Finally, we demonstrated lipid-lipid interactions mediated by zinc ions, resulting in hemi-fusion of vesicles lipid membrane mixing. The PtdHisOH lipid offers a new tool for facilitating vesicle aggregation and promoting cell-cell interaction, thereby enabling the formation of tissue-like structures. Its potential applications extend to biomedical fields, including targeted nanodelivery, leveraging the lipid's metal selectivity. Moreover, the lipid holds promise in the development of micromachines, facilitating in situ specific reactions.

description: Augmentative and alternative communication (AAC) can enhance children’s communication and is recommended to be introduced as soon as problems are identified. The aim of this interview study was to investigate how parents perceive the ComAlong Toddler intervention offered to parents of children with communication difficulties early in the diagnostic process. ComAlong Toddler consists of a 5-session, group-based, parental course, and two home visits that focus on responsive communication, enhanced milieu teaching, and multimodal AAC. Interviews were conducted 1 year after the intervention with 16 parents who had attended ComAlong Toddler. The data were analyzed through qualitative content analysis, resulting in four categories: (a) Development for us and the child, (b) acquiring useful tools, (c) useful learning strategies, and (d) benefits and challenges regarding intervention structure. Findings suggest that parents of toddlers with language or communication disorders learned and appreciated responsive communication and enhanced milieu teaching. All had used multimodal AAC and described its benefits. Parents emphasized the value of learning from other parents as well as from a speech-language pathologist who engaged with their child in the home environment. Parents suggest an enhanced family focus as a potential improvement.

description: Picea wilsonii is widely used for a forestation and landscaping in China. However, the molecular mechanisms underlying abiotic stress tolerance in this species remain elusive. In this study, we examined the transcriptomic changes induced by drought and salt stress in 8-week-old seedlings of P. wilsonii via RNA-Seq analysis; seedlings grown under normal conditions (without abiotic stress) served as a control. Approximately 36.26 Gb of transcriptome data were obtained from the three treatments. A total of 4171 (2579 up-regulated and 1732 down-regulated) and 3438 (1592 up-regulated and 1706 down-regulated) differentially expressed genes were identified under drought and salt treatments, respectively. Both RNA-Seq and qRT-PCR analyses showed that the expression of PwNAC genes, including PwNAC11, 24, 36, 38, 45, 47, 51 and 52, was greatly induced not only by salt stress but also by drought treatment, suggesting that these genes are involved in both salt and drought stress resistance in P. wilsonii. This is the first report of the transcriptome analysis of P. wilsonii. Our data will serve as a valuable genomic resource for the further characterization of the molecular mechanisms underlying abiotic stress tolerance in P. wilsonii.

description: Hydroxychloroquine (HCQ), the hydroxyl derivative of chloroquine (CQ), is widely used in the treatment of rheumatological conditions (systemic lupus erythematosus, rheumatoid arthritis) and is being studied for the treatment and prevention of COVID-19. Here, we investigate through mathematical modelling the safety profile of HCQ, CQ and other QT-prolonging anti-infective agents to determine their risk categories for Torsade de Pointes (TdP) arrhythmia. We performed safety modelling with uncertainty quantification using a risk classifier based on the qNet torsade metric score, a measure of the net charge carried by major currents during the action potential under inhibition of multiple ion channels by a compound. Modelling results for HCQ at a maximum free therapeutic plasma concentration (free Cmax) of approximately 1.2 µM (malaria dosing) indicated it is most likely to be in the high-intermediate-risk category for TdP, whereas CQ at a free Cmax of approximately 0.7 µM was predicted to most likely lie in the intermediate-risk category. Combining HCQ with the antibiotic moxifloxacin or the anti-malarial halofantrine (HAL) increased the degree of human ventricular action potential duration prolongation at some or all concentrations investigated, and was predicted to increase risk compared to HCQ alone. The combination of HCQ/HAL was predicted to be the riskiest for the free Cmax values investigated, whereas azithromycin administered individually was predicted to pose the lowest risk. Our simulation approach highlights that the torsadogenic potentials of HCQ, CQ and other QT-prolonging anti-infectives used in COVID-19 prevention and treatment increase with concentration and in combination with other QT-prolonging drugs.

description: We develop an effective nonhierarchical data clustering method using an analogy to the dynamic coarse graining of a stochastic system. Analyzing the eigensystem of an interitem transition matrix identifies fuzzy clusters corresponding to the metastable macroscopic states (macrostates) of a diffusive system. A "minimum uncertainty criterion" determines the linear transformation from eigenvectors to cluster-defining window functions. Eigenspectrum gap and cluster certainty conditions identify the proper number of clusters. The physically motivated fuzzy representation and associated uncertainty analysis distinguishes macrostate clustering from spectral partitioning methods. Macrostate data clustering solves a variety of test cases that challenge other methods.

description: The purity of a reduced state for spins that is pure in the rest frame will most likely appear to degrade because spin and momentum become mixed when viewed by a moving observer. We show that such a boost-induced decrease in spin purity observed in a moving reference frame is intrinsically related to the spatial localization properties of the wave package observed in the rest frame. Furthermore, we prove that, for any localized pure state with separable spin and momentum in the rest frame, its reduced density matrix for spins inevitably appears to be mixed whenever viewed from a moving reference frame.

description: Nonlocal strain gradient continuum mechanics is a methodology widely employed in literature to assess size effects in nanostructures. Notwithstanding this, improper higher-order boundary conditions (HOBC) are prescribed to close the corresponding elastostatic problems. In the present study, it is proven that HOBC have to be replaced with univocally determined boundary conditions of constitutive type, established by a consistent variational formulation. The treatment, developed in the framework of torsion of elastic beams, provides an effective approach to evaluate scale phenomena in smaller and smaller devices of engineering interest. Both elastostatic torsional responses and torsional free vibrations of nano-beams are investigated by applying a simple analytical method. It is also underlined that the nonlocal strain gradient model, if equipped with the inappropriate HOBC, can lead to torsional structural responses which unacceptably do not exhibit nonlocality. The presented variational strategy is instead able to characterize significantly peculiar softening and stiffening behaviours of structures involved in modern Nano-Electro-Mechanical-Systems (NEMS).

description: To evaluate and compare the effectiveness of resin- and varnish-based surface protective agents on Glass Ionomer Cement (GIC). The different surface protective agents used were: Vaseline®, GC Fuji VARNISH™ (varnish), G-Coat Plus™ (resin) and EQUIA® Coat (resin). Thirty-six identical specimens of GIC were made. Six specimens were used in preparation of standard solution and remaining thirty were divided into five groups with six specimens in each group. Each test specimen was coated with one of the surface protecting agent except for the control group. The specimens were immersed separately into 1 ml of 0.05% methylene blue solution for 24 h and then rinsed with deionised water and further immersed into tubes containing 1 ml of 65% nitric acid. Specimens, once completely dissolved in nitric acid solution, were filtered and centrifuged. The supernatant was used to determine the absorbance using a spectrophotometer. The effectiveness of the surface protecting agents for the GIC was recorded in micrograms of dye per specimen, where low values indicate good protection. Tukey HSD test revealed that GC Fuji VARNISH™ (varnish; mean = 21.25 µg/ml), G-Coat Plus™ (resin; mean = 30.39 µg/ml) and EQUIA® Coat (resin; mean = 9.32 µg/ml) were statistically not significantly different to each other and were effective in protecting the surface of GIC. The study found that there was a statistically significant difference between control and GC Fuji VARNISH™, G-Coat Plus™ and EQUIA® Coat. The three agents were found to be equally effective in protecting the surface of GIC.

description: With the aim of further advancing the understanding of the human brain’s functional connectivity, we propose a network metric which we term the geodesic entropy. This metric quantifies the Shannon entropy of the distance distribution to a specific node from all other nodes. It allows to characterize the influence exerted on a specific node considering statistics of the overall network structure. The measurement and characterization of this structural information has the potential to greatly improve our understanding of sustained activity and other emergent behaviors in networks. We apply this method to study how the psychedelic infusion Ayahuasca affects the functional connectivity of the human brain in resting state. We show that the geodesic entropy is able to differentiate functional networks of the human brain associated with two different states of consciousness in the awaking resting state: (i) the ordinary state and (ii) a state altered by ingestion of the Ayahuasca. The functional brain networks from subjects in the altered state have, on average, a larger geodesic entropy compared to the ordinary state. Finally, we discuss why the geodesic entropy may bring even further valuable insights into the study of the human brain and other empirical networks.

description: Tissue engineering is a fast progressing domain where solutions are provided for organ failure or tissue damage. In this domain, computer models can facilitate the design of optimal production process conditions leading to robust and economically viable products. In this study, we use a previously published computationally efficient model, describing the neotissue growth (cells + their extracellular matrix) inside 3D scaffolds in a perfusion bioreactor. In order to find the most cost-effective medium refreshment strategy for the bioreactor culture, a multi-objective optimization strategy was developed aimed at maximizing the neotissue growth while minimizing the total cost of the experiment. Four evolutionary optimization algorithms (NSGAII, MOPSO, MOEA/D and GDEIII) were applied to the problem and the Pareto frontier was computed in all methods. All algorithms led to a similar outcome, albeit with different convergence speeds. The simulation results indicated that, given the actual cost of the labor compared to the medium cost, the most cost-efficient way of refreshing the medium was obtained by minimizing the refreshment frequency and maximizing the refreshment amount.
