biodiversitydata-se/mol-mod: Target-prediction filtering added to ASV DB & portal
No full textIn this release, we make it possible to import all denoised sequences from a dataset, and then dynamically filter out any ASVs that we do not (currently) predict to derive from the targeted gene, thereby excluding these from BLAST and filter searches, result displays and IPT views. ASVs are thus only imported once, but their status can change, e.g. at taxonomic re-annotation. Criteria used for ASV exclusion may vary between genes / groups of organisms, but could e.g. combine the output from the BAsic Rapid Ribosomal RNA Predictor (barrnap) with the taxonomic annotation itself. For example, we may decide that only ASVs that are annotated at least at kingdom level OR get positive barrnap prediction should be considered as TRUE 16S rRNA sequences.
We implement this as follows:
Before import of a new dataset, we add the following annotation data to each ASV:
annotation_target = target gene of reference database used for taxonomic annotation (eg. 16S rRNA). At this stage, annotation_target will equal the target_gene of the dataset.
target_prediction = whether the ASV is predicted to derive from the annotation_target (TRUE/FALSE).
target_criteria = criteria used for setting target_prediction to TRUE (eg. 'Assigned kingdom OR Barrnap-positive', or 'None: defaults to TRUE').
During import, we compare annotation targets and predictions of ASVs in new datasets to annotations that already exist in db, with the following possible outcomes and responses:
-- target pred pred pred pred
db geneA TRUE FALSE TRUE FALSE
new geneA TRUE TRUE FALSE FALSE
-- ---- Ignore Check Check Ignore
db geneA TRUE FALSE TRUE FALSE
new geneB TRUE TRUE FALSE FALSE
-- ---- Check Update ignore Ignore
For example, in the top left case, an ASV in a new dataset comes in with an annotation for geneA, is also predicted to be a TRUE geneA sequence, and this corresponds with what is already noted in the database for that ASV, so we do nothing (the existing annotation remains). If, instead, a new dataset has a TRUE geneB prediction for an ASV that has previously been considered a FALSE geneA, this annotation can be automatically updated. Other conflicts likely require manual inspection and will cancel import with a notice of this. See /molmod/importer/importer.py and function compare_annotations for details.
After import, we filter all database views with an extended WHERE clause:
WHERE ta.status::text = 'valid'
# Criteria added for target prediction:
AND ta.target_prediction = true
AND ta.annotation_target::text = mixs.target_gene::text;
See /db/db-api-schema.sql
PKU-20: A new silicogermanate constructed from sti and asv layers
No full textA new silicogermanate (PKU-20) was hydrothermally synthesized using triethylisopropylammonium cation as the structure directing agent in the presence of fluoride. Its structure was determined from a combination of synchrotron single crystal X-ray diffraction and powder X-ray diffraction data. PKU-20 crystallizes in the monoclinic space group C2/m, with the lattice parameters of a = 18.5901(6) angstrom, b = 13.9118 (4) angstrom, c = 22.2614(7) angstrom and beta = 100.1514 (12)degrees. The framework of PKU-20 is constructed from an alternate stacking of sti and asv layers. The sti layer is exactly the same as that in the STI framework, while the asv layer is a new layer sliced off from the ASV framework parallel to the (112) plane. The takeout scheme of the layer is discussed on the basis of a composite building unit "D4R-/au-D4R". PKU-20 possesses a two-dimensional channel system, where the 10-ring channels parallel to the [010] direction are intercrossed by 12-ring pockets along the [101] direction. (C) 2016 Elsevier Inc.

Distributed Model Predictive Control for cooperative floating object transport with multi-vessel systems
No full textCompared to an individual Autonomous Surface Vessel (ASV), greater efficiency and operational capability can be realized by a team of cooperative ASVs for certain operations, such as search and rescue, hydrographic survey and navigation assistance. This paper focuses on cooperative floating object transport, i.e., a group of ASVs coordinate their actions to transport floating objects. We propose a multi-layer distributed control structure for the object transport system. The object transport problem is formulated as the combination of several sub-problems: trajectory tracking of the object, control allocation, and formation tracking of the ASVs. The sub-problems are integrated by a nonlinear towline model that describe the transformation of forces considering the mass and elasticity of the towline. A controller based on Model Predictive Control (MPC) is designed to control the motion of each ASV. A negotiation framework based on the Alternating Direction of Multipliers Method (ADMM) is then proposed to achieve consensus among the ASVs. Numerical simulations of utilizing the proposed cooperative system to move a large vessel sailing inbound the Port of Rotterdam are carried out to show the effectiveness of our method. Besides transporting barges and off-shore platforms, the proposed cooperative object transport system could also be a solution to coordinate non-autonomous vessels and ASVs in future autonomous ports where both human-operated and autonomous vessels exist.Accepted Author ManuscriptTransport Engineering and LogisticsMarine and Transport TechnologyShip Design, Production and Operation
Exploring a possible link between insulin resistance, vaccine to SARS CoV 2 and glycaemic disturbances in diabetes mellitus, type 2
No full textThe occurrence of both hyperglycaemia and hypoglycaemia, individually and in combination is reported in the literature, occurring in various insulin resistance (IR) syndromes, both to endogenous insulin, like Hirata disease, otherwise called the Insulin Autoimmune syndrome (IAS), type A, I R, Type B, IR etc. and to exogenous administered insulin, like, exogenous insulin antibody syndrome, (EIAS), non- classical auto immune syndrome to exogenous insulin, etc. Glycaemic disturbances without IR and in non-diabetics, like idiopathic and symptomatic reactive hypoglycaemias are also described in the literature. This author, recently reported for the first time, a biphasic post - vaccinal syndrome, following vaccination for Covid 19 (Covishield), causing glycemic disturbances in an elderly diabetes mellitus type 2 (DM2) patient on insulin who had moderate IR. Insulin resistance to exogenous insulin observed in the patient, is considered crucial for the occurrence of the observed clinical syndrome as, an increase or decrease of IR, and could explain the observed glycaemic disturbances. The IR to exogenous insulin, and the vaccine to Covid 19, both have immunological basis. The immunological aspects of both IR and the Covid 19 vaccine are briefly reviewed to explore any possible interaction between the two, that could explain the observed clinical syndrome, referred to above. Also, the various underlying mechanisms for the glycaemic disturbances, in the above-mentioned IR syndromes and non-IR or r syndromes are explored as to shed some light on the mechanism of the glycaemic disturbances in the syndrome reported. A hypothesis is suggested, taking into consideration, the aforesaid observations. Apart from IR to exogenous insulin, other unidentified factors that might be causing the clinical syndrome reported, and which might account for its paucity of reporting, need to be investigated by future research
RIGID AND NON-RIGID KINEMATIC EXCITATION FOR MULTIPLY-SUPPORTED SYSTEM: ONCE MORE ABOUT THE CONTRIBUTION OF DAMPING TO THE DYNAMIC LOADS IN SEISMIC ANALYSIS
No full textDevelopment of linear equations of motion for seismic analysis is discussed in the paper. The paper continues the discussion: the author does not agree with colleagues putting damping matrix into the right-hand part of the equation of motion describing dynamic loads. This disagreement refers to the most popular case of “rigid” motion of multiple supports. In this paper the author follows the logic of general “non-rigid” support motion and points out a step in the equation development when the transition to “rigid” support motion (as a particular case of “non-rigid” motion) is spoiled by the opponents. In the author’s opinion, the mistake is in the implementation of the Rayleigh damping model for the right-hand part of the equation. This is in the contradiction with physical logic, as damping in the Rayleigh model is not really “internal”: due to the participation of mass matrix it works on rigid displacements, which is impossible for internal damping.</jats:p
Distributed Dynamic Coordination Control for Offshore Platform Transportation Under Ocean Environmental Disturbances
No full textTransportation of a large offshore platform from inland waters to the open sea is a hazardous and challenging mission. With the development of the autonomous surface vessel (ASV), the problem of large floating object transportation has a chance to be solved by applying multiple physical-connected autonomous tugboats. This article proposes a distributed dynamic coordination control scheme for a multivessel autonomous towing system to transport an offshore platform under environmental disturbances. Where the dynamic coordination decision mechanism is based on the relative position of the two neighbor waypoints, the controllers are designed based on the multilayer model-predictive control (MPC) strategy with several specific cost functions, and the distributed control architecture is built based on the alternating direction method of multipliers (ADMM) with augmented Lagrangian function. The simulation experiment indicates that the proposed control scheme can achieve better consensus for the distributed control architecture accomplishment and more efficiently transport an offshore platform under environmental disturbances.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport Engineering and Logistic
