Usage of allergy codes in primary care electronic health records: a national evaluation in Scotland
No full textBackground: The UK's NHS intends to move from the current Read code system to the international, detailed Systematized Nomenclature of Medicine Clinical Terms (SNOMED-CT) to facilitate more clinically appropriate coding of conditions and associated risk factors and outcomes. Given concerns about coding behaviour of general practitioners, we sought to study the current coding patterns in allergies and identify lessons for the future migration to SNOMED-CT.Methods: Data from 2 014 551 primary care consultations in over 100 000 patients with one or more of 11 potentially allergic diseases (anaphylaxis, angioedema, asthma, conjunctivitis, drug allergies, eczema, food allergy, rhinitis, urticaria, venom allergy and other probable allergic disorders) from the Scottish Primary Care Clinical Informatics Unit Research (PCCIU-R) database were descriptively analysed and visualized to understand Read code usage patterns.Results: We identified 352 Read codes for these allergic diseases, but only 36 codes (10%) were used in 95% of consultations; 73 codes (21%) were never used. Half of all usage was for Quality and Outcomes Framework codes for asthma. Despite 149 detailed codes (42%) being available for allergic triggers, these were infrequently used.Conclusions: This analysis of Read codes use suggests that introduction of the more detailed SNOMED-CT, in isolation, will not improve the quality of allergy coding in Scottish primary care. The introduction of SNOMED-CT should be accompanied by initiatives aimed at improving coding quality, such as the definition of terms/codes, the availability of terminology browsers, a recommended list of codes and mechanisms to incentivize detailed coding of the condition and the underlying allergic trigger

A more comprehensive and commanding delineation: Mary Shelley's narrative strategy in Frankenstein
No full textThis thesis argues that the first edition of Frankenstein challenges conventional reading by employing what Simpson in Irony and Authority in Romantic Poetry calls Romantic irony, where the absence of a stable 'metacomment' precludes an authoritative reading. The novel hints at such readings but prevents them. The insights offered by Tropp's Mary Shelley's Monster, Baldick's In Frankenstein's Shadow, Poovey's The Proper Lady and the woman writer and Swingle's, 'Frankenstein's Monster and its Relatives: Problems of Knowledge in English Romanticism' are considered, but none recognises the full implications of the instability deriving from multiple first- person narratives. Clemit's The Godwinian Navel acknowledges the novel's indeterminacy, but reads a specific ideological purpose in it. Paradise Last provides a language to describe the relationship between the monster and Frankenstein, but proves too unstable to fix identity or establish moral value. Similarly, Necessity ultimately fails to provide a stable explanation in terms of cause and effect. The status of nature shifts between foreground and background, never allowing final definition. These uncertainties destabilise knowledge which is compromised by its provisional nature: no authoritative reading is possible, yet the novel has narrative coherence. The reader is encouraged to try to develop a reading the structure prevents. The radical nature of the first edition is highlighted by comparison with the 1831 edition, which removes much of the ambivalence and gives the novel a clearer morality. The novel challenges conventional methods of deriving authority by disturbing the reader's orthodox orientation in the world around him' (Simpson) in order to afford 'a point of view to the imagination for the delineation of human passions more comprehensive and commanding than any which the ordinary relations of existing events can yield' (Mary Shelley)
Orbit design for future SpaceChip swarm missions in a planetary atmosphere
No full textThe effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth. The orbit energy gain due to asymmetric solar radiation pressure, considering the Earth's shadow, is used to balance the energy loss due to atmospheric drag. Future missions for a swarm of SpaceChips are proposed, where a number of small devices are released from a conventional spacecraft to perform spatially distributed measurements of the conditions in the ionosphere and exosphere. It is shown that the orbit lifetime can be extended and indeed selected through solar radiation pressure and the end-of-life re-entry of the swarm can be ensured, by exploiting atmospheric drag
Enumeration of Stack-Sorting Preimages via a Decomposition Lemma
No full textWe give three applications of a recently-proven "Decomposition Lemma," which
allows one to count preimages of certain sets of permutations under West's
stack-sorting map . We first enumerate the permutation class
, finding a new example
of an unbalanced Wilf equivalence. This result is equivalent to the enumeration
of permutations sortable by , where is the bubble
sort map. We then prove that the sets ,
,
and are
counted by the so-called "Boolean-Catalan numbers," settling a conjecture of
the current author and another conjecture of Hossain. This completes the
enumerations of all sets of the form
for
with the exception of the set
. We also find an explicit formula for
, where
is the set of permutations in with descents.
This allows us to prove a conjectured identity involving Catalan numbers and
order ideals in Young's lattice
Reverse engineering of 3D-BIM of existing infrastructure using parametric tooling to accelerate the digitization transition in asset management: A research & development study by Colin Reit
No full textAmid global climate change challenges, the construction industry faces an urgent transition from a linear production model to a Circular Economy (CE). Initiatives and recommendations in Dutch transition roadmaps and literature predominantly focus on ensuring a future circular built environment, while lacking concrete actions on leveraging the existing assets for reuse. Dutch CE roadmap timelines and interventions are developed based on Material Flow Analysis (MFA) studies with highly uncertain data input, this uncertainty impacts either environment or economy with inaccurate interventions on the CE-transition. Secondly, the Replacement & Renovation (R&R) task of civil structures poses a threat for the industry due to the limitations of capital, contractor capacity, and material resources required to facilitate this peak. There is currently a lack of centrally stored high-quality physical asset data available at public organisations. This data is essential in effectively managing the decommissioning peak and reduces risk for reuse realization. Lastly, Asset Management (AM) is transitioning towards a 3D-centralised strategy in line with Building Information Modelling (BIM) and digital twins, while existing assets are still in 2D with often incomplete and fragmented data documentation. Consequently, a large data quality gap is forming between new and existing assets. This led to the research question: How can centrally stored, quantified, and visualised asset data of existing infrastructure impact the CE-transition, bridge R&R-task efficiency, and AM practices? An upgrade towards 3D-BIM is required for existing assets to bridge this data gap. In doing so, facilitate higher quality- and more accessible asset specific information that can be used in reusability scanning and structural assessments, material quantification for CE-transition roadmap accuracy, and numerous AM benefits. The costs for upgrading the existing assets using manual modelling or 3D scanning technology are currently too large to justify. An opportunity was identified for modelling 3D-BIM of existing beam & slab bridges from 2D drawings using a modular approach to Parametric Engineering, aiming to reduce the investment threshold, and accelerating the digitization transition. Preliminary testing executed by the author showed a potential for 50-80% reduction in modelling efforts compared to conventional modelling practices with a volume accuracy of >97%. The prototype calls for further development, validation, and similar efforts for other infrastructure types. The tool also showed potential for 3D structural & reusability assessments, reinforcement approx., and ptioneering & circularity scoring for the design phase. To put the tool’s use in perspective, a roadmap towards 3D centralized AM and a reuse economy was developed for AM. Civil Engineering | Construction Management and Engineerin
Results of monitoring at the British library excavation
No full textThe main phase of excavation for the basements of the British Library at St Pancras, London, was completed in 1987. The project included basements extending up to 25 m deep, through the London Clay and into the Lambeth Group. The excavations were formed using both the top-down method and open excavation with ground anchors. Existing major buildings lie within 25 m of the site and London Underground tunnels lie below and adjacent to the site. The purpose of this paper is to present the results of displacement monitoring; they are summarised in the paper and presented in more detail in online supplementary data files. The retaining walls advanced towards the site by up to about 32 mm and the clays expanded rapidly on unloading beneath the excavations, causing the Victoria Line tunnels to heave by up to 22 mm. The slow progress of the project provided an unusual opportunity to monitor ground and structure movements in the surroundings before site activity began. Ironically, it was found that the largest settlements of adjacent buildings were caused by the installation of equipment intended to measure the settlements. Extensive condition surveys were carried out, but no damage to adjacent structures or tunnels has been recorded.</p
