Molecular characterization of the ETV6-NTRK3 fusion in congenital fibrosarcoma
Creators: name: Wai, Daniel Hon-Hei
Publisher: name: University of British Columbia
Year: 2009

description: The t(12;15)(pl3;q25) rearrangement detected in congenital fibrosarcoma splices the ETV6 (TEL) gene on chromosome 12p13 in frame with the NTRK3 (TRKC) neurotrophin-3 receptor gene on chromosome 15q25. Resultant ETV6- NTRK3 fusion transcripts encode the helix-loop-helix (HLH) dimerization domain of ETV6 fused to the protein tyrosine kinase (PTK) domain of NTRK3. We hypothesize that chimeric proteins mediate transformation by dysregulating NTRK3 signal transduction pathways via ligand-independent dimerization and PTK activation. To determine if the fusion protein has transforming activity, NIH3T3 cells were infected with recombinant retroviral vectors carrying the full-length ETV6-NTRK3 cDNA. These cells exhibited a transformed phenotype and formed macroscopic colonies in soft agar. In order to characterize the roles of specific ETV6- NTRK3 domains, we expressed a series of ETV6-NTRK3 mutants in NIH3T3 cells and assessed their transformation activities. Deletion of the ETV6 H L H domain resulted in morphologically non-transformed NIH3T3 cells that failed to grow in soft agar. Mutants of the three PTK activation-loop tyrosines (EN-Y513, EN-Y517, and EN-Y518) had variable PTK activity but had limited to absent transformation activity. The EN-Y513F mutant failed to transform NIH3T3 cells, while the expression of either EN-Y517F or EN-Y518F resulted in a semi-transformed phenotype. The simultaneous mutation of Y517 and Y518 (EN-Yx2F), or of all three tyrosines (EN-Yx3F), resulted in a morphologically untransformed phenotype. The ATP-binding mutant (EN-K380N) failed to autophosphorylate and completely lacked transformation activity. In addition, a series of PTK-active mutants unable to bind phospholipase-Cγ did not show defects in transformation activity. These studies confirm that ETV6-NTRK3 is a transforming protein that requires both an intact dimerization domain and a functional PTK domain for transformation activity.

description: We analyze the equilibrium statistical mechanics of canonical, non-canonical and non-Hamiltonian equations of motion by throwing light into the peculiar geometric structure of phase space. Some fundamental issues regarding time translation and phase space measure are clarified. In particular, we emphasize that a phase space measure should be defined by means of the Jacobian of the transformation between different types of coordinates since such a determinant is different from zero in the non-canonical case even if the phase space compressibility is null. Instead, the Jacobian determinant associated with phase space flows is unity whenever non-canonical coordinates lead to a vanishing compressibility, so that its use in order to define a measure may not be always correct. To better illustrate this point, we derive a mathematical condition for defining non-Hamiltonian phase space flows with zero compressibility. The Jacobian determinant associated with time evolution in phase space is altogether useful for analyzing time translation invariance. The proper definition of a phase space measure is particularly important when defining the entropy functional in the canonical, non-canonical, and non-Hamiltonian cases. We show how the use of relative entropies can circumvent some subtle problems that are encountered when dealing with continuous probability distributions and phase space measures. Finally, a maximum (relative) entropy principle is formulated for non-canonical and non-Hamiltonian phase space flows.

description: The gravitationally induced entanglement is a type of quantum entanglement that can be generated between two mesoscopic particles using their Newtonian gravitational interaction. It has attracted a great deal of attention as a new platform for studying quantum aspects of gravity. The present paper analyzes the gravitationally induced entanglement as a pure interference effect and shows that the entanglement is induced solely by a sign change associated with the destructive quantum interference. It is also shown that when the entanglement is non-maximal, the preparation for destructive interference for one of the particles can recover a maximum visibility interference pattern for the other particle. Therefore, the non-maximally entangled state can be extremely effective for experimental testing since it can help in reducing requirements (on masses of the particles and their interaction duration, separation distances and sources) and preserve the information about entanglement at the same time. As a result, the improvement in the signal-to-noise ratio is demonstrated and a parameter that determines minimal requirements for experimental testing is defined.

description: Исследования проводили с целью изучения влияния оптимизации условий минерального питания на урожайность смеси проса посевного с рапсом яровым, водный и питательный режимы луговочерноземной почвы южной лесостепи Западной Сибири. Работу выполняли в Омской области в 2011-2013 гг. в стационарном полевом опыте в восьмипольном севообороте с выводными полями многолетних трав и чередованием зернобобовых культур с однолетними травами и зерновыми. Схема опыта включала следующие варианты: обеспеченность почвы подвижным фосфором (фактор А) - средняя, 50...100 мг/кг по Чирикову (I); повышенная, 100.120 мг/кг (II) и 140.150 мг/кг (III); высокая, 150.200 мг/кг(IV); фосфорное удобрение (фактор B) - Р0, Р60; азотное удобрение (фактор C) - N0, N30, N60. Эксперимент реализован методом наложения удобрений на фоны различной обеспеченности почвы фосфором. Почва - лугово-черноземная среднемощная среднегумусная тяжелосуглинистая. Реакция почвенной среды в пахотном слое нейтральная. Сорт рапса ярового - Юбилейный, проса посевного - Омское 16. Сочетание изучаемых факторов в опыте обеспечивало снижение коэффициента водопотребления с 44,2 до 29,6 мм/т сухого вещества для первого полуметра и с 49,5 до 31,5 мм/т для метрового слоя, или на 33 и 36 % соответственно. Содержание нитратного азота в почве после уборки культуры уменьшается в несколько раз и стабилизируется на низком уровне - 2,1...3,8 мг/кг. Применение фосфорсодержащих удобрений компенсирует вынос элемента с урожаем культуры, не уменьшая почвенного плодородия. Значительная доля в смеси высокобелковой культуры (50...70 %) и наличие богатой углеводами мятликовой культуры (19.27 %) обеспечивает необходимое сахаро-протеиновое соотношение в производимом корме. При этом возделывание проса в смеси с рапсом малозатратно и позволяет сформировать более 30 т/га зеленой массы, в том числе 6,0.6,5 т/га сухого вещества.

description: The Hispanic population in the United States has grown significantly in the last 20 years, becoming the largest minority group in the U.S., accounting for 14.8% of the total U.S. population. Hispanics have also become an important economic force in U.S. consumer spending. This study analyzes factors affecting the demand for meats relative to Hispanic consumers’ region of origin, such as Mexico (Mexican, Mexican-American, and Chicano), Puerto Rico, Cuba (Cuban and Cuban American), Central and South American, and other Hispanics. Since Hispanic consumers tend to live in communities with similar ethnic origins, this is expected to impact the demand for food in these communities. Factors such as income, household size, age, gender, and educational attainment are also included in the analysis.

description: Решение актуальной на сегодняшний день задачи, связанной со снижением объемов применения гербицидов, может быть успешно реализовано путем дифференцированного их использования, когда норма расхода препарата или рабочей жидкости изменяется в период обработки в зависимости от уровня засоренности. Цель исследований - оценка эффективности дифференцированного проведения гербицидной обработки, основанного на спектральных измерениях состояния посева. Работу проводили на посевах ярового ячменя сорта Ленинградский в Ленинградской области в 2015, 2017-2018 гг. Схемой опыта была предусмотрена сильная, средняя и слабая засоренность делянок, а также равномерное (полная норма расхода гербицида независимо от степени засоренности делянок) и дифференцированное (норму расхода гербицида варьировали в зависимости от степени засоренности по данным наземного определения индекса NDVI) применение гербицидов, контролем служил вариант без обработки гербицидом. Более предпочтительной по влиянию на засоренность (на 13,7...18,5 % по численности, на 9,8.18,4 % по фитомассе) и формирование урожая (на 1.13 %) была равномерная обработка. При этом дифференцированная на основе измерений вегетационного индекса NDVI норма расхода гербицида обеспечивала примерно такое же снижение численности и фитомассы сорных растений, как и полная норма (по численности 58,6 и 64,1% соответственно, по фитомассе - 70,3 и 75,7%). Однако более высокая рентабельность гербицидной обработки дважды из трех лет исследований достигалась в варианте с дифференцированным проведением защитных мероприятий вследствие значительного (на 39.41 %) снижения объемов применения препарата.

description: In this paper we present an improved lattice Boltzmann model for compressible Navier-Stokes system with high Mach number. The model is composed of three components: (i) the discrete-velocity-model by Watari and Tsutahara [Phys Rev E \textbf{67},036306(2003)], (ii) a modified Lax-Wendroff finite difference scheme where reasonable dissipation and dispersion are naturally included, (iii) artificial viscosity. The improved model is convenient to compromise the high accuracy and stability. The included dispersion term can effectively reduce the numerical oscillation at discontinuity. The added artificial viscosity helps the scheme to satisfy the von Neumann stability condition. Shock tubes and shock reflections are used to validate the new scheme. In our numerical tests the Mach numbers are successfully increased up to 20 or higher. The flexibility of the new model makes it suitable for tracking shock waves with high accuracy and for investigating nonlinear nonequilibrium complex systems.

description: In the past, studies on agricultural feedstocks for energy production were motivated by rising fossil fuel prices interpreted by many as caused by resource depletion. However, today's studies are mainly motivated by concerns for climate change and global warming. Currently, most studies concentrate on liquid fuels with little study devoted toward electricity. This study examines crop residues for electricity production in the context of climate change and global warming. We use sector modeling to simulate future market penetration for biopower production from crop residues. Our findings suggest that crop residues cost much more than coal because they have lower heat content and higher production/hauling costs. For crop residues to have any role in electricity generation either the carbon or carbon dioxide equivalent greenhouse gas price must rise to about 15 dollars per ton or the price of coal has to increase to about 43 dollars per ton. We find crop residues with higher heat content and lower production costs such as wheat residues have greater opportunities in biopower production than the residues with lower heat content and higher production costs. In addition, the analysis shows that improvements in crop yield do not have much impact on biopower production. However, the energy recovery efficiency does have significant positive impact but only if the carbon equivalent price rises substantially. The analysis also indicates the desirability of cofiring biomass as opposed to 100% replacement because this reduces hauling costs and increases the efficiency of heat recovery. In terms of policy implications, imposing carbon emission pricing could be an important step in inducing electric power producers to include agricultural biomass in their fuel-mix power generation portfolios and achieve greenhouse gas emission reductions.

description: The aim of this study was to determine the efficacy, safety and acceptability of a 4-week very-low-energy diet (VLED) program for adolescents with obesity. Adolescents (13-17 years) with obesity and ≥1 obesity-related complication were Fast Track to Health 52-week randomized controlled trial participants. Adolescents undertook a 4-week micronutrient-complete VLED (800 kcal/day), with weekly dietitian support. Anthropometric data were recorded at baseline and week-4 and side-effects at day 3-4, week-1, -2, -3 and -4. Adolescents completed an acceptability survey at week-4. A total of 134 adolescents (14.9 ± 1.2 years, 50% male) had a 5.5 ± 2.9 kg (p < 0.001) mean weight loss at week-4: 95% experienced ≥1 and 70% experienced ≥3 side-effects during the VLED program, especially during the first week. Hunger, fatigue, headache, irritability, loose stools, constipation and nausea were most common. Reporting more side-effects at day 3-4 correlated with greater weight loss at week-4 (r = -0.188, p = 0.03). Adolescents reported 'losing weight' (34%) and 'prescriptive structure' (28%) as the most positive aspects of VLED, while 'restrictive nature' (45%) and 'meal replacement taste' (20%) were least liked. A dietitian-monitored short-term VLED can be implemented safely and is acceptable for many adolescents seeking weight loss, despite frequent side-effects. Investigating predictors of acceptability and effectiveness could determine adolescents most suited to VLED programs.

description: CKD disproportionately affects Black and Hispanic/Latino individuals. APOL1 risk variants are common in individuals of recent African ancestry and explain some disparities. However, not all individuals with APOL1 high-risk genotypes develop CKD, suggesting gene-environment and gene-gene (epistatic) modifiers. Prior genetic studies studying single nucleotide polymorphism (SNP) interactions with APOL1 risk genotypes were limited by small sample sizes and did not identify genome-wide significant interactions. We conducted a genome-wide SNP-APOL1 interaction analysis using two large datasets with genetic and phenotypic data.

description: We report results from preliminary analysis of the recently constructed dataset from the Farm Service Agency, FSA 1614. FSA 1614 provides the location of the farm and the farm payment recipient for all Title I payments. This makes it possible to analyze the spatial dispersion between landowner and farm more precisely than previously possible. A discussion of what research questions could be informed through the use of this data is provided. We find that a significant percentage of payments are sent to individuals that are likely to be absentee landowners, although this value is much smaller when looking at the total value of payments. These national results are compared to four corn belt states.

description: A critical task in graph signal processing is to estimate the true signal from noisy observations over a subset of nodes, also known as the reconstruction problem. In this paper, we propose a node-adaptive regularization for graph signal reconstruction, which surmounts the conventional Tikhonov regularization, giving rise to more degrees of freedom; hence, an improved performance. We formulate the node-adaptive graph signal denoising problem, study its bias-variance trade-off, and identify conditions under which a lower mean squared error and variance can be obtained with respect to Tikhonov regularization. Compared with existing approaches, the node-adaptive regularization enjoys more general priors on the local signal variation, which can be obtained by optimally designing the regularization weights based on Prony's method or semidefinite programming. As these approaches require additional prior knowledge, we also propose a minimax (worst-case) strategy to address instances where this extra information is unavailable. Numerical experiments with synthetic and real data corroborate the proposed regularization strategy for graph signal denoising and interpolation, and show its improved performance compared with competing alternatives.

description: This study takes advantages of recent developments in measuring total factor productivity in output specific directions to examine the influence of technological change in different agricultural sectors on land-use decisions in a cross-section of countries from 1969 to 2001. Results demonstrate a positive relationship between productivity and land in agriculture in most cases. The ruminant sector is an exception where an increase in productivity was negatively associated with amount of pastureland. The analysis also includes variables that have been found to be important determinants in other studies of land-use change. Population is clearly the dominant factor over the time period analyzed, although it is argued that other factors are likely to become more important in upcoming years since population growth has slowed significantly in many countries.

description: We present a phenomenological study of photon-initiated (PI) lepton production at the LHC, as implemented in the structure function (SF) approach. We provide detailed predictions for multi-differential lepton pair production, and show that the impact on observables sensitive to the the weak mixing angle, $\sin^2 θ_W$, and $W$ boson mass, $M_W$, as well as PDFs can be non-negligible, in particular given the high precision being aimed for. The SF calculation can provide percent level precision in the corresponding production cross sections, and is therefore well positioned to account for LHC precision requirements. We consider the pure $γγ$ channel, and compare in detail to the NLO collinear calculation. We in addition include initial-state $Z$ as well as mixed $γ/Z + q$ contributions, and assess their impact. We also consider photon-initiated lepton-lepton scattering, and again find the SF approach can provide high precision predictions for this process in way that can straightforwardly account for any fiducial cuts imposed. Finally, we provide a publicly available Monte Carlo generator, SFGen, for PI lepton pair production and lepton-lepton scattering within the SF approach, for use by the community.

В эксперименте изучали отзывчивость трех новых сортов мягкой яровой пшеницы (Новосибирская 16, Новосибирская 41 и Сибирская 21) на разные уровни химической защиты посевов от вредных организмов: без применения инсектицидов и фунгицидов - контроль; протравливание семян; протравливание семян + инсектициды; фунгициды (протравливание семян и обработка растений в фазе колошения) + инсектициды. Обработку инсектицидами проводили в фазах всходы и колошение. Почва - чернозем выщелоченный среднесуглинистый. Предшественник - чистый пар. Условия 2018 г. оказались наиболее благоприятными для размножения вредителей, значимых различий в развитии листостебельных болезней в зависимости от года исследований не выявлено. Сорт Сибирская 21 показал относительную устойчивость к мучнистой росе и пшеничному трипсу. Хлебная полосатая блошка менее интенсивно заселяла посевы сорта Новосибирская 16, внутристеблевые вредители практически не повреждали растения Новосибирской 41. На фунгицидную обработку семян лучше всего отзывался сорт Новосибирская 41 - при бавка урожая составила 0,39 т/га, наименее отзывчивым был сорт Сибирская 21 (прибавка 0,09 т/га). Самую высокую величину дополнительного урожая от применения инсектицидов обеспечил сорт Новосибирская41 (0,60 т/га), самую низкую - Новосибирская 16 (0,24 т/га). При умеренном развитии листостебельных болезней отзывчивость сортов на использование фунгицидов в период вегетации различалась слабо, дополнительный сбор зерна варьировал от 0,24 до 0,33 т/га. Наибольшей урожайностью как при использовании комплекса фитосанитарных средств, так и без их применения характеризовался сорт Сибирская 21 (4,35.5,11 т/га), значительно меньше она была у сорта Новосибирская 41 (3,45.4,68 т/га), самой низкой - у сорта Новосибирская 16 (2,55.3,40 т/га).

description: This study ventures into the dynamic realm of ecosystem orchestration for industrial firms, emphasizing its significance in maintaining competitive advantage in the digital era. The fragmented research on this important subject poses challenges for firms aiming to navigate and capitalize on ecosystem orchestration. To bridge this knowledge gap, we conducted a comprehensive qualitative meta-analysis of 31 case studies and identified multifaceted orchestration practices employed by industrial firms. The core contribution of this research is the illumination of five interdependent but interrelated orchestration practices: strategic design, relational, resource integration, technological, and innovation. Together, these practices are synthesized into an integrative framework termed the "Stirring Model," which serves as a practical guide to the orchestration practices. Furthermore, the conceptual framework clarifies the synergy between the identified practices and highlights their collective impact. This study proposes theoretical and practical implications for ecosystem orchestration literature and suggests avenues for further research.

description: A precise link is derived between scalar-graviton S-matrix elements and expectation values of operators in a worldline quantum field theory (WQFT), both used to describe classical scattering of a pair of black holes. The link is formally provided by a worldline path integral representation of the graviton-dressed scalar propagator, which may be inserted into a traditional definition of the S-matrix in terms of time-ordered correlators. To calculate expectation values in the WQFT a new set of Feynman rules is introduced which treats the gravitational field $h_{μν}(x)$ and position $x_i^μ(τ_i)$ of each black hole on equal footing. Using these both the next-order classical gravitational radiation $\langle h^{μν}(k)\rangle$ (previously unknown) and deflection $Δp_i^μ$ from a binary black hole scattering event are obtained. The latter can also be obtained from the eikonal phase of a $2\to2$ scalar S-matrix, which we show to correspond to the free energy of the WQFT.

description: Growth in early infancy is hypothesized to affect chronic disease risk factors later in life. To date, most reports draw on European-ancestry cohorts with few repeated observations in early infancy. We investigated the association between infant growth before 6 months and lipid levels in adolescents in a Hispanic/Latino cohort. We characterized infant growth from birth to 5 months in male (n = 311) and female (n = 285) infants from the Santiago Longitudinal Study (1991-1996) using 3 metrics: weight (kg), length (cm), and weight-for-length (g/cm). Superimposition by translation and rotation (SITAR) and latent growth mixture models (LGMMs) were used to estimate the association between infant growth characteristics and lipid levels at age 17 years. We found a positive relationship between the SITAR length velocity parameter before 6 months of age and high-density lipoprotein cholesterol levels in adolescence (11.5, 95% confidence interval; 3.4, 19.5), indicating higher high-density lipoprotein cholesterol levels occurring with faster length growth. The strongest associations from the LGMMs were between higher low-density lipoprotein cholesterol and slower weight-for-length growth, following a pattern of associations between slower growth and adverse lipid profiles. Further research in this window of time can confirm the association between early infant growth as an exposure and adolescent cardiovascular disease risk factors.

description: Machine-to-machine (M2M) and the internet of things (IoT) have brought a massive surge of smart connected devices that will enable new services and applications. In this paper, we present the implementation of these emerging technologies in the “Smart building”, one of its most popular usages. Our proposed solution represents a complete system for M2M-IoT-based smart building that collects information from heterogeneous communication technologies (Ethernet, Bluetooth, and GSM). We design the M2M-IoT-based smart building using Arduino UNO as a microcontroller unit, shields (Ethernet W5100, SIM800L, and Bluetooth HC-06) as the wireless communications, and Blynk App as a local server that provides the ability to control the building remotely via Ethernet/Bluetooth connectivity and mobile networks like 4G or 5G. One of the most important results of this work is the success in creating a model of a smart building system based on M2M-IoT that accomplishes several services such as smart parking, lighting control, gas and fire detection, and climate control. All these services are implemented to control the building remotely, ensure safety and comfort, as well as energy-saving by using efficacy and cheap components.

description: Рассматривается опыт освоения адаптивно-ландшафтных систем земледелия (АЛСЗ) в регионах страны в связи с различным участием местных органов власти в инновационной деятельности. Особо выделяются достижения в земледелии Белгородской области, где разработанная система проектирования и освоения АЛСЗ была сопряжена с крупными социально-экономическими преобразованиями, в том числе с развитием социальной инфраструктуры села, гармонизацией различных форм хозяйствования и др. В то же время есть примеры неудовлетворительной организации освоения АЛСЗ в ряде других регионов. Сегодня на фоне неопределившейся государственной аграрно-экономической политики с ее либеральными перекосами чрезвычайно важна роль региональных организационных структур. Необходима адаптация земледелия к потеплению климата, в том числе к использованию дополнительных ресурсов тепла в условиях Севера. Среди государственных задач по научноорганизационному и инновационному обеспечению земледелия, а также его технологической модернизации можно назвать развитие земельной службы на базе агрохимической, организацию инновационно-технологических центров и научно-инновационных систем, создание учебно-производственной базы и новых образовательных программ в аграрных вузах, восстановление координации научных исследований в региональных НИИ. Особое внимание следует уделить формированию системы комплексной оценки сельскохозяйственных земель.

description: Government involvement in agricultural R&D is justified if the benefits exceed the costs. Does the private sector neglect socially profitable investments? So-called market failures in R&D can result if inventors are unable to fully appropriate the returns to their inventions - if "free-riders"-can adopt new technology and benefit from it without having to contribute to the costs of research. In agriculture, in particular, it seems likely that, absent government intervention, the private sector will invest too little in certain types of R&D, and there is a strong in-principle case for government to intervene either to improve private incentives or, more directly, to fund or undertake research. In the United States, both state and federal governments are extensively involved in agricultural R&D. Perhaps the most obvious, and arguably the main form of involvement is the government production of agricultural science - in government labs or in public Universities - using general government revenues. This intervention is justified both in principle and by the evidence that the rates of return to public agricultural research have been very high, even with very extensive government intervention to correct the private-sector under-investment in agricultural R&D (e.g., see Alston et al. 2000). This suggests that the government intervention to date has been inadequate; that the United States could have profitably spent much more on agricultural R&D. These observations apply to differing extents to different elements of U.S. agricultural R&D in aggregate in terms of fields of science, locations of production, or commodity orientation of research. This paper considers public funding for R&D directed to specialty crops. Specific questions to be addressed include whether R&D for specialty crops has been under-funded, both in absolute terms and relative to other crops and agriculture more generally. First, evidence is presented on past funding patterns and on rates of return; second implications of that evidence in the context of specialty crops production are discussed.

description: The quantum confinement of Rydberg excitons is an important step towards exploiting their large nonlinearities for quantum applications. We observe Rydberg excitons in natural nanoparticles of Cu$_2$O. We resolve up to the principal quantum number $n=12$ in a bulk Cu$_2$O crystal and up to $n=6$ in nanoparticles extracted from the same crystal. The exciton transitions in nanoparticles are broadened and their oscillator strengths decrease as $\propto n^{-4}$ compared to those in the bulk (decreasing as $\propto n^{-3}$). We explain our results by including the effect of quantum confinement of exciton states in the nanoparticles. Our results provide an understanding of the physics of Cu$_2$O Rydberg excitons in confined dimensions.

description: Interferometric observations with three telescopes or more provide two observables: closure phase information together with visibilities measurements. When using single-mode interferometers, both observables have to be redefined in the light of the coupling phenomenon betwe en the incoming wavefront and the fiber. We introduce in this paper the estimator of both so-called modal visibility and modal closure phase. Then, we compute the statistics of the two observables in presence of partial correction by Adaptive Optics. From this theoretical analysis, data reduction process using classical least square minimization is investigated. In the framework of the AMBER instrument, the three beams recombiner of the VLTI, we simulate the observation of a single Gaussian source and we study the performances of the interferometer in terms of diameter measurements. We show that the observation is optimized, i.e. that the Signal to Noise Ratio (SNR) of the diameter is maximal, when the full width half maximum (FWHM) of the source is roughly 1/2 of the mean resolution of the interferometer. We finally point out that in the case of an observation with 3 telescopes, neglecting the correlation between the measurements leads to overestimate the SNR by a factor of $\sqrt{2}$. We infer that in any cases, this value is an upper limit.

description: Background: The role of Residential Childcare Workers (RCWs) in the UK is pivotal in providing support to children and young people in care who have complex emotional and behavioural needs. Behaviours that challenge (BTC) present a multifaceted issue which has been shown to significantly impact on the emotional well-being of RCWs (Kor et al., 2021). However, an understanding of how RCWs make sense of BTC is theoretically and empirically underdeveloped. Thus, the present study aimed to conduct an in-depth exploration of RCWs’ experiences of behaviours that challenge, uncovering their individual perspectives, interpretations, and responses to such behaviours, in order to identify effective strategies for supporting RCWs in their role. Method: This qualitative study utilised semi-structured interviews to explore the subjective experiences of eight RCWs in the UK. The data was analysed using Interpretative Phenomenological Analysis (Smith & Nizza, 2022). Results: The findings highlighted the profoundly personal and relational nature of RCWs’ experiences when confronted with BTC. The study provides an in-depth exploration of the diverse and nuanced perceptions of BTC as experienced by RCWs. It delves into the various coping strategies employed by RCWs in response to BTC and examines the barriers they encounter while supporting children and young people in care. Conclusion: The findings have important implications for residential childcare practice in the UK. Recommendations for practice have been suggested, emphasising the need for selfreflective practice, peer support and ongoing training and development.
Magnetism as a mass term of the edge states in graphene

description: The magnetism by the edge states in graphene is investigated theoretically. An instability of the pseudo-spin order of the edge states induces ferrimagnetic order in the presence of the Coulomb interaction. Although the next nearest-neighbor hopping can stabilize the pseudo-spin order, a strong Coulomb interaction makes the pseudo-spin unpolarized and real spin polarized. The magnetism of the edge states makes two peaks of the density of states in the conduction and valence energy bands near the Fermi point. Using a continuous model of the Weyl equation, we show that the edge-induced gauge field and the spin dependent mass terms are keys to make the magnetism of the edge states. A relationship between the magnetism of the edge states and the parity anomaly is discussed.

description: Restricting the $\mathbb{Z}_2$-graded tensor product of Clifford algebras $C\ell_4\hat{\otimes}C\ell_6 $ to the particle subspace allows a natural definition of the Higgs field $Φ$, the scalar part of Quillen's superconnection, as an element of $C\ell_4^1$. We emphasize the role of the exactly conserved weak hypercharge Y, promoted here to a superselection rule for both observables and gauge transformations. This yields a change of the definition of the particle subspace adopted in recent work with Michel Dubois-Violette \cite{DT20}; here we exclude the zero eigensubspace of Y consisting of the sterile (anti)neutrinos which are allowed to mix. One thus modifies the Lie superalgebra generated by the Higgs field. Equating the normalizations of $Φ$ in the lepton and the quark subalgebras we obtain a relation between the masses of the W boson and the Higgs that fits the experimental values within one percent accuracy.
