description: The fractional Ornstein-Uhleneck (fOU) process is described by the overdamped Langevin equation $\dot{x}(t)+γx=\sqrt{2 D}ξ(t)$, where $ξ(t)$ is the fractional Gaussian noise with the Hurst exponent $01/2$) spectral density at zero frequency. For $H>1/2$, the fOU is long-correlated. Here we study dynamical large deviations of the fOU process and focus on the area $A_n=\int_{-T}^{T} x^n(t) dt$, $n=1,2,\ldots$ over a long time window $2T$. Employing the optimal fluctuation method, we determine the optimal path of the conditioned process, which dominates the large-$A_n$ tail of the probability distribution of the area, $\mathcal{P}(A_n,T)\sim \exp[-S(A_n,T)]$. We uncover a nontrivial phase diagram of scaling behaviors of the optimal paths and of the action $S(A_n\equiv 2 a_n T,T)\sim T^{α(H,n)} a^{2/n}_n$ on the $(H,n)$ plane. The phase diagram includes three regions: (i) $H>1-1/n$, where $α(H,n)=2-2H$, and the optimal paths are delocalized, (ii) $n=2$ and $H\leq \frac{1}{2}$, where $α(H,n)=1$, and the optimal paths oscillate with an $H$-dependent frequency, and (iii) $H\leq 1-1/n$ and $n>2$, where $α(H,n)=2/n$, and the optimal paths are strongly localized. We verify our theoretical predictions in large-deviation simulations of the fOU process. By combining the Wang-Landau Monte-Carlo algorithm with the circulant embedding method of generation of stationary Gaussian fields, we were able to measure probability densities as small as $10^{-170}$. We also generalize our findings to other stationary Gaussian processes with either diverging, or vanishing spectral density at zero frequency.

description: A regulamentação de segurança das instalações reveste‐se da maior relevância, não só em consideração à vida humana, como à própria actividade económica. Motivada pela constante evolução da tecnologia, do surgimento de novos materiais e equipamentos e das exigências funcionais dos espaços, a regulamentação de segurança requer uma constante actualização e adaptação a essa novas necessidades e exigências. Cada vez mais a segurança de pessoas e bens é uma directriz fundamental aquando da realização dos projectos e execução dos edifícios, dos mais diversos fins. De forma a precaver situações que possam colocar em risco pessoas e bens, são consideradas medidas activas e passivas de protecção, das quais poderemos destacar os sistemas de detecção automática de incêndio, detecção automática de intrusão, sinalização de saída, etc. Assim, a especial preocupação com a segurança de pessoas e bens justifica a importância ocupada pela segurança, a qual exige a necessidade de se assegurar a forma como são projectadas, executadas, exploradas e conservadas, em geral as instalações e em particular as instalações de segurança dos edifícios. Torna‐se, pois, imperioso garantir‐se o cumprimento, por parte de todos de todos os agentes envolvidos (projectistas, instaladores...), da aplicação dos regulamentos estabelecidos para as instalações de Segurança. Esta tarefa apenas poderá ser conseguida se houver um conhecimento completo e profundo dos diplomas legais que enquadram a área de segurança dos edifícios. O presente trabalho tem, pois, por objectivo, sistematizar e apresentar a presente regulamentação contra incêndios em edifícios, bem como apresentar o futuro Regulamento de Segurança Contra Incêndio em Edifícios, que vem criar um inovador enquadramento nesta área, por forma a serem garantidas as exigências mínimas de protecção de pessoas, instalações e bens.

Auditory temporal processing ability and the development of speech, language and reading: implications for children with auditory neuropathy spectrum disorder

description: Auditory Neuropathy Spectrum Disorder (ANSD) is classified by normal cochlear mechanical function but severely degraded neural synchrony. The auditory system relies on high levels of neural synchrony for processing timing (temporal) cues which are critical for speech perception (particularly in degraded conditions) and normal speech, language and reading development. Unlike most sensorineural hearing losses, speech perception ability in ANSD appears to be correlated with the magnitude of temporal disruption rather than spectral disruption (measured either through the pure tone audiogram or estimated by frequency-specific auditory brainstem responses; ABR). Because ANSD is mostly diagnosed in infants through newborn hearing screening programs, objective tests of temporal processing are needed. The current study focused on the development and evaluation of objective tests of temporal processing for children. Specifically, the aims of the present study were to: identify the likely types of disruptions that occur to speech perception, language and reading abilities in young children with abnormal temporal processing, and the magnitude of disruption that can affect these skills; develop and evaluate objective measures of temporal processing in normally hearing adults to provide sensitive measures of assessing different auditory temporal processing abilities; and evaluate the applicability of these objective measures to normally hearing children (aged 5-12) with normal speech, language and reading abilities and to normally hearing older adults with poor temporal processing abilities (aged 64-80 years). This study provides normative data for objective temporal processing measures, which ultimately can be used to evaluate temporal processing abilities in children with ANSD unable to provide behavioural responses. Because of the heterogeneous nature of the disorder and co-morbidity of other medical problems in this population, research in this area is limited. Nonetheless, developing a greater understanding of this problem is critical to improved management of children diagnosed with ANSD and other temporal deficits.

description: Ao longo das últimas décadas, o nosso estilo e hábitos de vida tem vindo, paulatinamente, a ser alterados e melhorados, a par do desenvolvimento das economias, e dos progressos tecnológicos, contribuindo, sobremaneira para uma melhoria generalizada das condições sociais. Com desenvolvimento do sector económico tem‐se assistido em Portugal à implementação de ambientes liberalizados em áreas tradicionalmente controladas pelo estado e, assim, sujeitas a um verdadeiro regime de monopólio, como eram os casos do sector energético e das telecomunicações. A publicação do Decreto‐Lei n.º 59/2000, de 19 de Abril e a subsequente publicação das Prescrições Técnicas de Instalações e Especificações Técnicas de Equipamentos e Materiais, projectou Portugal para a vanguarda de um verdadeiro ambiente concorrencial ao nível das telecomunicações. O presente artigo visa, sucintamente, reflectir sobre o novo enquadramento das Infra‐estruturas de Telecomunicações em Edifício (ITED) criado pelo DL n.º 59/2000, de 19 de Abril, assim como, evidenciar os aspectos mais específicos desse mesmo enquadramento.

description: We propose a two-dimensional plasmonic platform - periodically patterned monolayer graphene - which hosts topological one-way edge states operable up to infrared frequencies. We classify the band topology of this plasmonic system under time-reversal-symmetry breaking induced by a static magnetic field. At finite doping, the system supports topologically nontrivial bandgaps with mid-gap frequencies up to tens of terahertz. By the bulk-edge correspondence, these bandgaps host topologically protected one-way edge plasmons, which are immune to backscattering from structural defects and subject only to intrinsic material and radiation loss. Our findings reveal a promising approach to engineer topologically robust chiral plasmonic devices and demonstrate a realistic example of high-frequency topological edge state.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Purpose: To establish a relationship between impairment of the anterograde axonal transport (AAT) in the axons of the retinal ganglion cells and the intraocular pressure (IOP) during aging in mice with hereditary glaucoma. Methods: Quantitative in vivo approach based on manganese enhanced magnetic resonance imaging was developed in order to evaluate AAT in 3-, 6-, and 14-month old DBA/2J mice that develop age-dependent pigmentary glaucoma or age-matched C57Bl/6 mice that do not develop any retinal disease. Unilateral intravitreous administration of MnCl2 solution was followed 24 h later by MRI performed to obtain spin-lattice relaxation times (T1) for regions of interest encompassing the superior colliculi (SC) and the lateral geniculate nuclei (LGN). From the MRI scans, the estimates of Mn2+ concentrations in SC and LGN contralateral to the injection site, hence the efficiency of AAT in ON, were obtained. IOP and eye morphology was also monitored. Results: In C57Bl/6 mice, AAT to SC was decreasing with age, 30% decrease was noted between 3 and 14 months. The decrease in axonal transport to LGN was less pronounced in this strain. In 3-month-old DBA/2J mice, axonal transport to SC was 30% lower than in 3-month-old C57Bl/6 mice but no significant decrease was noted in 6-month-old animals. However, a decrease of over 95% in axonal transport both to SC and LGN was noted in 14-month-old DBA/2J mice. DBA/2J mice exhibited a sharp increase in IOP at 6 months, which reversed at 14 months but displayed age-dependent elongation of the eyeball and deepening of the anterior chamber. Conclusion: Failure of AAT to SC of DBA/2J mice during development of pigmentary glaucoma does not follow closely changes in IOP and eye morphology. The relationship between IOP and AAT in optic nerve and tract is complex and may reflect preconditioning mechanism.

description: Apesar de muito utilizada no sector industrial, a automação ainda não atingiu o mesmo patamar de implementação no sector doméstico. A evolução tecnológica leva a que quase todos os dias apareçam novos produtos que visam a implementação de sistemas domóticos que possibilitem o conforto, a segurança e a eficiência nas habitações. Contudo, quando se pretende instalar um sistema domótico com o objectivo de simplificar os processos numa habitação, a palavra que surge não é “simplicidade”, mas sim “complicação”. Para além de a grande maioria das pessoas não estar familiarizada com as funcionalidades que um sistema domótico permite, existe sempre o pensamento que esses sistemas têm um custo elevado, o que de certa forma não é um pensamento errado. Se quanto ao aspecto do preço, não há muito a fazer, ele depende das leis do mercado e do custo da inovação, quanto à complexidade da instalação e utilização dos sistemas, trata‐se de um pensamento induzido nas pessoas que não conhecem os sistemas domóticos e que facilmente se consegue desmistificar. Os projectos de domótica nas habitações deveriam ser pensados aquando do projecto da habitação. No entanto, a realidade não é essa. A grande maioria das habitações não foi pensada para a instalação desses sistemas e só depois da instalação eléctrica estar efectuada e a habitação habitada é que se percebe que se precisava de ter mais alguma flexibilidade e funcionalidade na instalação. A evolução tecnológica permitiu desenvolver soluções para este tipo de situações. Hoje em dia não é necessário reconstruir a habitação para instalar sistemas domóticos. Existem soluções que usam a rede eléctrica já instalada e que permitem instalar funções domóticas na habitação.

description: Studies in the field of second language acquisition have long been interested in the phenomenon of Foreign Language Anxiety (FLA) (e.g., Horwitz, Horwitz & Cope, 1986; MacIntyre & Gardner, 1994). These studies confirm that many L2 learners experience anxiety during the process of language learning. In terms of speaking anxiety, current research points to the need to better understand this phenomenon. Recent research focusing on Saudi foreign language learners points to the important role of cultural factors and speaking context in speaking anxiety (e.g., Al-Saraj 2014a; Javid, 2014). However, much of this research has been done in Saudi Arabia, and a gap exists in the current research literature pertaining to the relationship between speaking anxiety and language learning among Saudi ESL learners in mixed-gender classrooms. This study aimed to investigate the triggers of speaking anxiety for nine Saudi ESL learners studying in Australia. It also examined the manifestations of such anxiety, as well as coping strategies identified by the participants. Participants were observed in a classroom context participating in three types of speaking activities: pair work, group work, and oral presentation. This was followed by individual semi-structured interviews and stimulated recall sessions. Analysis of the data revealed five socio-contextual factors contributing to participants’ experiences of anxiety, including proximity to learners of the opposite gender, two psycho-linguistic factors including fear of incorrect L2 usage, and three overlap factors including linguistically demanding speaking tasks. The manifestations of speaking anxiety among the participants were both physical and psychological in nature and included avoiding eye contact, holding onto objects tensely, and forgetting words. The main coping strategies reported by the study cohort were learning additional vocabulary and undertaking thorough preparation prior to speaking. The findings from this study have implications for pedagogical practices related to teacher behaviour, classroom management practices, and the design of learning activities when instructing Saudi ESL learners.

Nesta obra Fourier demonstrava que a condução do calor nos corpos sólidos podia ser descrita através de uma série infinita de senos e co‐senos. O trabalho estimulou investigações nos mais variados campos da ciência e da técnica, tendo ressaltado que o tipo de formulação matemática empregada por Fourier era um pré‐requisito para a solução de fenómenos que exibiam natureza periódica. O método de exprimir funções periódicas em termos de somas de senos e co‐senos recebe o nome de Análise Harmónica.

Ambulance disinfection using Ultraviolet Germicidal Irradiation (UVGI): Effects of fixture location and surface reflectivity

description: Ambulances are frequently contaminated with infectious microorganisms shed by patients during transport that can be transferred to subsequent patients and emergency medical service workers. Manual decontamination is tedious and time-consuming, and persistent contamination is common even after cleaning. Ultraviolet germicidal irradiation (UVGI) has been proposed as a terminal disinfection method for ambulance patient compartments. However, no published studies have tested the use of UVGI in ambulances. The objectives of this study were to investigate the efficacy of a UVGI system in an ambulance patient compartment and to examine the impact of UVGI fixture position and the UV reflectivity of interior surfaces on the time required for disinfection. A UVGI fixture was placed in the front, middle, or back of an ambulance patient compartment, and the UV irradiance was measured at 49 locations. Aluminum sheets and UV-reflective paint were added to examine the effects of increasing surface reflectivity on disinfection time. Disinfection tests were conducted using Bacillus subtilis spores as a surrogate for pathogens. Our results showed that the UV irradiance varied considerably depending upon the surface location. For example, with the UVGI fixture in the back position and without the addition of UV-reflective surfaces, the most irradiated location received a dose of UVGI sufficient for disinfection in 16 s, but the least irradiated location required 15 hr. Because the overall time required to disinfect all of the interior surfaces is determined by the time required to disinfect the surfaces receiving the lowest irradiation levels, the patient compartment disinfection times for different UVGI configurations ranged from 16.5 hr to 59 min depending upon the UVGI fixture position and the interior surface reflectivity. These results indicate that UVGI systems can reduce microbial surface contamination in ambulance compartments, but the systems must be rigorously validated before deployment. Optimizing the UVGI fixture position and increasing the UV reflectivity of the interior surfaces can substantially improve the performance of a UVGI system and reduce the time required for disinfection.

description: We compute a subset of three, velocity-independent four-loop (and fourth post-Newtonian) contributions to the harmonic-coordinates effective action of a gravitationally interacting system of two point-masses. We find that, after summing the three terms, the coefficient of the total contribution is rational, due to a remarkable cancellation between the various occurrences of $π^2$. This result, obtained by a classical field-theory calculation, corrects the recent effective-field-theory-based calculation by Foffa et al. [arXiv:1612.00482]. Besides showing the usefulness of the saddle-point approach to the evaluation of the effective action, and of x-space computations, our result brings a further confirmation of the current knowledge of the fourth post-Newtonian effective action. We also show how the use of the generalized Riesz formula [Phys. Rev. D 57, 7274 (1998)] allows one to analytically compute a certain four-loop scalar master integral (represented by a four-spoked wheel diagram) which was, so far, only numerically computed.

description: The Convention on the Rights of Persons with Disabilities (CRPD) has been hailed as a paradigm shift to protect the human rights of persons with disabilities. It has been implemented for 8 years. This thesis investigates whether the CRPD is an advance in the protection of human rights of persons with disabilities. It does so by examining the normative rules under, and the actual implementation of, the CRPD by States Parties, and by examining the work of the CRPD Committee. The thesis yields the theoretical and normative insights that the CRPD possesses inherent merits and values for creating platforms for positive changes for advancing the human rights of persons with disabilities. It does so by selectively adopting the most reasonable aspects of theoretical understandings of disability, equality and discrimination. Normatively, it prioritises transforming the legal concepts and normative rules into concrete results in which persons with disabilities are able to exercise their legal capacity while being protected from institutionalisation and involuntary medical treatment in a barrier-free environment. A related conclusion is that the implementationof the theoretical concepts and selected normative rights depends upon the national legal framework and good intentions of States Parties. It also concluded that the CRPD Committee did not face any difficulty in determining violations and holding States Parties liable for not fulfilling their treaty obligations. This thesis therefore concludes that the CRPD has in practice to some extent protected the human rights of persons with disabilities. The CRPD may not solve all the problems that persons with disabilites are facing, but it can contribute to protecting their human rights if properly implemented and with the participation of all stakeholders including persons with disabilities in the implementation and monitoring process.

description: The expression patterns of endogenous circular RNA (circRNA) molecules during epidermal stem cell (EpSC) differentiation have not previously been explored. Here, we show that circRNAs are abundantly expressed in EpSCs and that their expression change dramatically during differentiation in a coordinated manner. Overall, circRNAs are expressed at higher levels in the differentiated cells, and many upregulated circRNAs are derived from developmental genes, including four different circRNAs from DLG1. The observed changes in circRNA expression were largely independent of host gene expression, and circRNAs independently upregulated upon differentiation are more prone to AGO2 binding and have more predicted miRNA binding sites compared to stably expressed circRNAs. In particular, upregulated circRNAs from the HECTD1 and ZNF91 genes have exceptionally high numbers of AGO2 binding sites and predicted miRNA target sites, and circZNF91 contains 24 target sites for miR-23b-3p, which is known to play important roles in keratinocyte differentiation. We also observed that upregulated circRNAs are less likely to be flanked by homologues inverted Alu repeats compared to stably expressed circRNAs. This coincide with DHX9 being upregulated in the differentiated keratinocytes. Finally, none of the circRNAs upregulated upon differentiation were also upregulated upon DNMT3A or DNMT3B knockdown, making it unlikely that epigenetic mechanisms are governing the observed circRNA expression changes. Together, we provide a map of circRNA expression in EpSCs and their differentiated counterparts and shed light on potential function and regulation of differentially expressed circRNAs.

To that end, we begin by deriving the equations of motion for the dynamics of collinear ferrimagnets in the presence of a charge current. The obtained equations of motion reduce to those of ferromagnets and antiferromagnets at two special limits. In the collective coordinate approach, a skyrmion behaves as a massive charged particle moving in a viscous medium subjected to a magnetic field. Analogous to the snake orbits of electrons in a nonuniform magnetic field, we show that a ferrimagnet with the nonuniform angular momentum density can exhibit snake trajectories of skyrmions, which can be utilized as racetracks for skyrmions.

description: This article explores the implication of urban expansion on shared natural resources and livelihoods in peri-urban areas of Wa municipality of Northwestern Ghana using mainly qualitative research methods. The study shows that rapid urban expansion is the main driver of the depletion of shea trees and livelihood transformation of the people living in these hitherto rural areas. Peri-urbanization manifests in many forms including the clearing of shea trees to make way for sand/stone mining and residential housing. The lumbering of shea trees for charcoal making and fuelwood to meet urban energy demands and the breakdown of traditional customary laws and the non-existence of land use plans in these areas are further factors behind the depletion of shea trees. The study concludes that peri-urbanization of Wa and its rural surroundings is not producing the desired transformations in livelihood, but rather poses an enormous challenge for the use and management of shea trees for the population whose livelihoods depend on them. Drawing on these processes and recognition of trade-offs between objectives, uses and users, relevant policy options are recommended.

description: During its first 4 months of taking data, Advanced LIGO has detected gravitational waves from two binary black hole mergers, GW150914 and GW151226, along with the statistically less significant binary black hole merger candidate LVT151012. We use our rapid binary population synthesis code COMPAS to show that all three events can be explained by a single evolutionary channel -- classical isolated binary evolution via mass transfer including a common envelope phase. We show all three events could have formed in low-metallicity environments (Z = 0.001) from progenitor binaries with typical total masses $\gtrsim 160 M_\odot$, $\gtrsim 60 M_\odot$ and $\gtrsim 90 M_\odot$, for GW150914, GW151226, and LVT151012, respectively.

description: Narratives are temporally sequenced accounts of events and have a broad importance to social, academic and language development. Individuals with autism spectrum disorder (ASD) characteristically have difficulties with social communication and have been found to produce narratives that are less structurally complex than typically developing peers. Five papers are included in this thesis by publication. In the first paper a systematic literature review is presented examining research into the effects of narrative intervention on the oral narratives of children with communication disorders. Overall the literature supports the use of narrative intervention to develop narrative macrostructure in children with oral communication disorders. Only four studies included participants with a diagnosis of ASD. Existing research supports the use of macrostructure icons, participants telling entire narratives and clinician modelling within intervention. In the remaining four papers intervention studies are described that address the development of oral narrative macrostructure. In the first intervention study, a multiple baseline with probe design was used to examine the effects of intervention on the personal narratives of four children with ASD and severe language disorder. The same design was used to examine the effects of intervention on the fictional narrative retells on four children with ASD and severe language disorder. The third intervention study was a pilot AB study with one participant with ASD and language disorder that examined an original fictional narrative intervention. Following on from this pilot study, a multiple baseline with probe design was employed in the final intervention study to examine an original fictional narrative intervention with four children with ASD and language disorder. All studies included maintenance and generalisation probes. Overall, the narrative interventions appeared to be effective in improving the macrostructure for most participants, but individual responses were variable and modifications to the intervention procedures were necessary for some participants. There was evidence of maintenance for most participants and some evidence of generalisation to other people and settings.This thesis adds to the limited research into narrative intervention with children with ASD and significant language disorder. The studies presented provide evidence that intervention can be effective across a range of narrative types but individual responses to intervention may be idiosyncratic and some children may require individualised adjustments. The thesis also provides the first study of narrative retell intervention with this population.

Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Superplastic forming of metals and alloys is known as a technological process of deformation, of those materials which are characterized by a structure well defined and uniform as grain size around of 10 micrometers, at medium temperature, and with very low strain rate. All of these conditions makes the process unattractive, but the benefits are quite major and valuable. The complexity of shapes deformed and obtained, the large and uniform dimension of parts, are some of these major benefits of this kind of deformation process. Although of these benefits, the superplastic forming process are quite difficult for simulating and analysis process. The finite element method comes to facilitate the analysis and simulation of the flow and forming process. The present work is focused on this objective: to show a method for simulation and finite element analysis of superplastic forming, using the unconventional software ANSYS.

description: We report on observation of a fine structure of microwave-induced resistance oscillations in an ultraclean two-dimensional electron gas. This fine structure is manifested by multiple secondary sharp extrema, residing beside the primary ones, which emerge at high radiation power. Theoretical considerations reveal that this fine structure originates from multiphoton-assisted scattering off short-range impurities. Unique properties of the fine structure allow us to access all experimental parameters, including microwave power, and to separate different contributions to photoresistance. Furthermore, we show that the fine structure offers a convenient means to quantitatively assess the correlation properties of the disorder potential in high-quality systems, allowing separation of short- and long-range disorder contributions to the electron mobility.

description: Supply Chain Management often requires independent organizations to work together to achieve shared objectives. This collaboration is necessary when coordinated actions benefit the group more than the uncoordinated efforts of individual firms. Despite the commonly reported benefits that can be gained in close relationships, recent research has indicated that collaboration attempts between purchasing firms and their suppliers have not been as widespread as anticipated. Using a survey of procurement professionals, this research investigates how the purchasing function utilizes collaboration in its supply chain relationships. Structural equation modeling is used to identify how information sharing, decision synchronization, incentive alignment, collaborative communication, and trust impact collaboration, as well as how collaboration impacts performance. Results from 86 survey responses indicate that firms are still not fully utilizing collaborative relationships.

description: Pooling of individual-level data for workers involved in uranium refining and processing (excluding enrichment) may provide valuable insights into risks from occupational uranium and external ionizing radiation exposures. Data were pooled for workers from four uranium processing facilities (Fernald, Mallinckrodt and Middlesex from the U.S.; and Port Hope, Canada). Employment began as early as the 1930s and follow-up was as late as 2017. Workers were exposed to high concentrations of uranium, radium, and their decay products, as well as gamma radiation and ambient radon decay products. Exposure and outcome data were harmonized using similar definitions and dose reconstruction methods. Standardized mortality ratios (SMR) were estimated. In total, 560 deaths from lung cancer, 503 non-malignant respiratory diseases, 67 renal diseases, 1,596 ischemic heart diseases, and 101 dementia and Alzheimer's disease (AD) were detected in the pooled cohort of over 12,400 workers (∼1,300 females). Mean cumulative doses were 45 millisievert for whole-body external ionizing radiation exposure and 172 milligray for lung dose from radon decay products. Only SMR for dementia and AD among males was statistically significant (SMR=1.29; 95% confidence interval: 1.04, 1.54). This is the largest study to date to examine long-term health risks of uranium processing workers.

description: We report on nonlinear magnetotransport in a two-dimensional electron gas hosted in a MgZnO/ZnO heterostructure. Upon application of a direct current, we observe pronounced Hall field-induced resistance oscillations (HIRO) which are well known from experiments on high-mobility GaAs/AlGaAs quantum wells. The unique sensitivity of HIRO to the short-range component of the disorder potential allows us to unambiguously establish that the mobility of our MgZnO/ZnO heterostructure is limited by impurities residing within or near the 2D channel. Demonstration that HIRO can be realized in a system with a much lower mobility, much higher density, and much larger effective mass than in previously studied systems, highlights remarkable universality of the phenomenon and its great promise to be used in studies of a wide variety of emerging 2D materials.
