description: We study the velocity structure of penumbral filaments in the deep photosphere to obtain direct evidence for the convective nature of sunspot penumbrae. A sunspot was observed at high spatial resolution with the 1-m Swedish Solar Telescope in the deep photospheric C I 5380 Å absorption line. The Multi-Object Multi-Frame Blind Deconvolution (MOMFBD) method is used for image restoration and straylight is filtered out. We report here the discovery of clear redshifts in the C I 5380 Å line at multiple locations in sunspot penumbral filaments. For example, bright head of filaments show larger concentrated blueshift and are surrounded by darker, redshifted regions, suggestive of overturning convection. Elongated downflow lanes are also located beside bright penumbral fibrils. Our results provide the strongest evidence yet for the presence of overturning convection in penumbral filaments and highlight the need to observe the deepest layers of the penumbra in order to uncover the energy transport processes taking place there.

description: The gut microbiota is composed of trillions of microbial cells and viruses that interact with hosts. The composition of the gut microbiota is influenced by several factors including age, diet, diseases, or medications. The impact of drugs on the microbiota is not limited to antibiotics and many non-antibiotic molecules significantly alter the composition of the intestinal microbiota. This review focuses on the impact of four of the most widely prescribed non-antibiotic drugs in the world: Proton-pump inhibitors, metformin, statins, and non-steroidal anti-inflammatory. We conducted a systematic review by searching online databases including Medline, Web of science, and Scopus for indexed articles published in English until February 2021. We included studies assessing the intestinal microbiome alterations associated with proton pump inhibitors (PPIs), metformin, statins, and nonsteroidal anti-inflammatory drugs (NSAIDs). Only studies using culture-independent molecular techniques were included. The taxonomical signature associated with non-antibiotic drugs are not yet fully described, especially in the field of metabolomic. The identification of taxonomic profiles associated a specific molecule provides information on its mechanism of action through interaction with the intestinal microbiota. Many side effects could be related to the dysbiosis induced by these molecules.
Investigating montbretin A biosynthesis and elucidating acyltransferase in Crocosmia x crocosmiiflora
Creators: name: Jo, Seohyun

Year: 2019

description: Plant specialized metabolites have been historically used in traditional medicine, flavours and fragrances throughout centuries, and they still serve as a valuable source for new pharmaceutical and nutraceutical development. Montbretin A (MbA) is an acylated flavonol glycoside produced by the ornamental plant montbretia (Crocosmia x crocosmiiflora), and mainly accumulates in the underground storage organs, called corms. This unique metabolite is a highly specific inhibitor of the human pancreatic α-amylase (HPA), thus making it a promising candidate for drug development against type-2 diabetes. However, a production system for obtaining large quantities of MbA is currently unavailable. Metabolic engineering of MbA in alternative microbial or plant systems may lead to the large-scale production of MbA. The main goal of this thesis was to obtain foundational insight on MbA biosynthesis. I first examined the growth and development of the montbretia plant, and performed detailed metabolite analysis focusing on the corms. The results of the metabolite profiling revealed the spatiotemporal patterns of MbA biosynthesis. This provided a foundational knowledge for the development of the montbretia transcriptome by Irmisch et al. (submitted). Furthermore, based on the activity of corm protein extracts, I identified that a member of the BAHD-AT family is involved in the acylation step of MbA biosynthesis. The candidate BAHD-ATs were identified using the established montbretia transcriptome, and were cloned and heterologously expressed in Escherichia coli for functional characterization. Of the seven candidate ATs tested, two candidates, CcAT1 and CcAT2 catalyzed the formation of mini-MbA, the product of the third step of MbA biosynthesis. Additionally, CcAT1 and CcAT2 were transiently expressed in the leaves of Nicotiana benthamiana, which led to the formation of a surrogate mini-MbA compound. This provided preliminary insight towards the metabolic engineering of MbA in N. benthamiana. Furthermore, qRT-PCR analyses were performed to investigate the transcript abundance patterns of CcAT1 and CcAT2 during montbretia corm development. The transcript profiling of CcAT1 and CcAT2 further supported their in vivo roles of MbA biosynthesis. Overall, the results presented in this thesis provide new knowledge on specialized plant metabolism in a non-model plant species.

description: Products may communicate a premeditated story, one that has been planned and designed from the products’ conception. This story may be communicated through designed ‘triggers’ or ‘cues’ that are all part of the product’s form, material, intractability and manufacture. How and if designed objects achieve their goal of communicating with responders and establishing an emotional connection, will be explored through a series of interviews with end-users in relation to the work of award winning practice bernabeifreeman. The bernabeifreeman designers have identified four key storytelling methods in their work as: Narrative, Manufacture, History and Interaction.
Balance Functions from Au+Au, d+Au, and p+p Collisions at $\sqrt{s_{NN}}$ = 200 GeV

description: Balance functions have been measured for charged particle pairs, identified charged pion pairs, and identified charged kaon pairs in Au+Au, d+Au, and p+p collisions at $\sqrt{s_{NN}}$ = 200 GeV at the Relativistic Heavy Ion Collider using the STAR detector. These balance functions are presented in terms of relative pseudorapidity, $Δη$, relative rapidity, $Δy$, relative azimuthal angle, $Δϕ$, and invariant relative momentum, $q_{\rm inv}$. In addition, balance functions are shown in terms of the three components of $q_{\rm inv}$: $q_{\rm long}$, $q_{\rm out}$, and $q_{\rm side}$. For charged particle pairs, the width of the balance function in terms of $Δη$ scales smoothly with the number of participating nucleons, while HIJING and UrQMD model calculations show no dependence on centrality or system size. For charged particle and charged pion pairs, the balance functions widths in terms of $Δη$ and $Δy$ are narrower in central Au+Au collisions than in peripheral collisions. The width for central collisions is consistent with thermal blast-wave models where the balancing charges are highly correlated in coordinate space at breakup. This strong correlation might be explained either by delayed hadronization or by limited diffusion during the reaction. Furthermore, the narrowing trend is consistent with the lower kinetic temperatures inherent to more central collisions. In contrast, the width of the balance function for charged kaon pairs in terms of $Δy$ shows little centrality dependence, which may signal a different production mechanism for kaons. The widths of the balance functions for charged pions and kaons in terms of $q_{\rm inv}$ narrow in central collisions compared to peripheral collisions, which may be driven by the change in the kinetic temperature.

description: Diffusion of point-like non interacting particles in a two-dimensional (2D) channel of varying cross section is considered. The particles are biased by a constant force in the transverse direction. We apply our recurrence mapping procedure, which enables us to derive an effective one-dimensional (1D) evolution equation, governing the 1D density of the particles in the channel. In the limit of stationary flow, we arrive at an extended Fick-Jacobs equation, corrected by an effective diffusion coefficient D(x), depending on the longitudinal coordinate x. Our result is an approximate formula for D(x), involving also influence of the transverse force. Our calculations are verified on the stationary diffusion in a linear cone, which is exactly solvable.

description: The universe of potentially interesting, searchable literature is expanding continuously. Besides the normal expansion, there is an additional influx of literature because of interdisciplinary boundaries becoming more and more diffuse. Hence, the need for accurate, efficient and intelligent search tools is bigger than ever. Even with a sophisticated search engine, looking for information can still result in overwhelming results. An overload of information has the intrinsic danger of scaring visitors away, and any organization, for-profit or not-for-profit, in the business of providing scholarly information wants to capture and keep the attention of its target audience. Publishers and search engine engineers alike will benefit from a service that is able to provide visitors with recommendations that closely meet their interests. Providing visitors with special deals, new options and highlights may be interesting to a certain degree, but what makes more sense (especially from a commercial point of view) than to let visitors do most of the work by the mere action of making choices? Hiring psychics is not an option, so a technological solution is needed to recommend items that a visitor is likely to be looking for. In this presentation we will introduce such a solution and argue that it is practically feasible to incorporate this approach into a useful addition to any information retrieval system with enough usage.

description: Modern cyber-physical systems (CPS) can consist of various networked components and agents interacting and communicating with each other. In the context of spatially distributed CPS, these connections can be dynamically dependent on the spatial configuration of the various components and agents. In these settings, robust monitoring of the distributed components is vital to ensuring complex behaviors are achieved, and safety properties are maintained. To this end, we look at defining the automaton semantics for the Spatio-Temporal Reach and Escape Logic (STREL), a formal logic designed to express and monitor spatio-temporal requirements over mobile, spatially distributed CPS. Specifically, STREL reasons about spatio-temporal behavior over dynamic weighted graphs. While STREL is endowed with well defined qualitative and quantitative semantics, in this paper, we propose a novel construction of (weighted) alternating finite automata from STREL specifications that efficiently encodes these semantics. Moreover, we demonstrate how this automaton semantics can be used to perform both, offline and online monitoring for STREL specifications using a simulated drone swarm environment.

description: Recently, several papers have been dedicated to the Wigner quantization of different Hamiltonians. In these examples, many interesting mathematical and physical properties have been shown. Among those we have the ubiquitous relation with Lie superalgebras and their representations. In this paper, we study two one-dimensional Hamiltonians for which the Wigner quantization is related with the orthosymplectic Lie superalgebra osp(1|2). One of them, the Hamiltonian H = xp, is popular due to its connection with the Riemann zeros, discovered by Berry and Keating on the one hand and Connes on the other. The Hamiltonian of the free particle, H_f = p^2/2, is the second Hamiltonian we will examine. Wigner quantization introduces an extra representation parameter for both of these Hamiltonians. Canonical quantization is recovered by restricting to a specific representation of the Lie superalgebra osp(1|2).

description: One of the major issues in road safety is the slipperiness of the topcoat surface of the road during rainfalls. The presence of water on the pavement surface reduces friction on the topcoat surface. In the absence of sufficient friction, accidents caused by slipping seem inevitable. A common phenomenon during rain is hydroplaning. The hydroplaning characteristics are affected by water film thickness, tire inflation pressure, pavement texture depth, surface hydraulic properties, and tire tread depth. The present study aims to determine the impact of superhydrophobic coating of octafluoropentyl methacrylate (OFPMA) on the hydroplaning risk and water layers thickness in asphalt pavements. For this purpose, a device for simulating rainy conditions on asphalt pavements was designed. The water flow velocity over a variety of uncoated and coated asphalt surfaces with various degrees of the superhydrophobic coating was measured and the hydroplaning speed was calculated. According to the results, the mean values of the hydroplaning speed of a vehicle on the coated asphalt samples were roughly 1.33 times greater than the uncoated asphalt samples. Furthermore, the outcomes in this paper indicated that superhydrophobic coatings could be an innovative method to mitigate hydroplaning risk and decrease water film thickness on pavements.
Envelope protection of preservative-treated pine decking with modified low molecular weight phenol formaldehyde resin

Publisher: name: University of British Columbia
Year: 2019

description: Preservative-treated pine is commonly used for outdoor decking in Canada and the United States, but its attractive appearance is lost when it is exposed to the weather. Wood can be protected from ‘weathering’ using low molecular weight phenol formaldehyde (LMW PF) resin. In this thesis, I combine preservative treatments and modification of wood with PF resin to try to develop wood decking with superior resistance to weathering. My hypothesis is that shallow ‘envelope’ modification of treated wood with LMW PF resin containing photostabilizers and wax additives will protect the appearance of preservative-treated pine decking exposed to natural weathering. I first screened different additives for their ability to protect wood from the adverse effects of weathering. The best additives were selected for further testing. Preservative-treated Scots and southern pine boards were modified by dipping or vacuum impregnation with modified PF resins, and modified and treated boards were exposed to the weather. Envelope modification restricted checking of untreated pine boards weathered for two years. Degradation of modified boards was shallow and easily cleaned off. Underneath the weathered grey layer, the colour of PF-modified wood was retained. Envelope modification with different PF resin formulations also protected treated boards weathered for six months. Ferric chloride was a more effective additive than a lignin stabilizer for most substrates (treated or untreated). The dark colour of PF/ferric-modified wood masked mould. The different PF resins I tested improved the performance of treated wood to varying degrees, but their effectiveness depended on the substrate they were applied to. I conclude that: (1) envelope modification with PF and modified PF resins is able to protect treated decking from the adverse effects of weathering; (2) vacuum impregnation with PF resin is a better method than dipping at creating an effective weather-resistant envelope at the surface of treated wood decking; (3) PF and additives need to be tailored to suit different preservative-treated woods; (4) PF modification shows promise as a finishing process to enhance weathering resistance of treated wood.

Autonomy and Singularity in Dynamic Fracture

description: The recently developed weakly nonlinear theory of dynamic fracture predicts $1/r$ corrections to the standard asymptotic linear elastic $1/\sqrt{r}$ displacement-gradients, where $r$ is measured from the tip of a tensile crack. We show that the $1/r$ singularity does not automatically conform with the notion of autonomy (autonomy means that any crack tip nonlinear solution is uniquely determined by the surrounding linear elastic $1/\sqrt{r}$ fields) and that it does not automatically satisfy the resultant Newton's equation in the crack parallel direction. We show that these two properties are interrelated and that by requiring that the resultant Newton's equation is satisfied, autonomy of the $1/r$ singular solution is retained. We further show that the resultant linear momentum carried by the $1/r$ singular fields vanishes identically. Our results, which reveal the physical and mathematical nature of the new solution, are in favorable agreement with recent near tip measurements.

description: The interaction between homing and parental care offers insights about the motivational aspects underlying movement patterns in animals. For species that care for offspring at fixed locations, offspring mortality in the absence of care might impact a parent’s motivation to home after being displaced from young. We tested whether homing motivation is related to parental care in the glassfrog Centrolene savagei (Centrolenidae), a species with extended male care and territoriality. Specifically, we evaluated how parental status (i.e. caring for eggs vs unmated yet territorial males) and translocation distance impacts homing motivation. Along a stream located in the Central Andes of Colombia, we translocated 23 male C. savagei between 5 and 80 m away from their reproductive territories. We found that both parental status and translocation distance impacts homing motivation, as caring males were more likely to return to their initial territories after translocation. Seven of the 16 caring males and one of the seven unmated males returned to the initial capture site. While unmated males might be motivated to home if reproductive territories are a limited resource, our results support that caring males exhibited much higher motivation to home. It is possible that the fitness benefits accrued from caring for vulnerable offspring alters the cost-to-benefits of homing, and thus accounts for a greater frequency of homing among caring males. This study contributes to understanding how aspects of life history (e.g. parental care) relate to homing motivation in vertebrates.

description: Spectral synthesis is basically the decomposition of an observed spectrum in terms of the superposition of a base of simple stellar populations of various ages and metallicities, producing as output the star formation and chemical histories of a galaxy, its extinction and velocity dispersion. The STARLIGHT code provides one of the most powerful spectral synthesis tools presently available. We have applied this code to the entire Six-Degree-Field Survey (6dF) sample of nearby star-forming galaxies, selecting dwarf galaxy candidates with the goal of: (1) deriving the age and metallicity of their stellar populations and (2) creating a database with the physical properties of our sample galaxies together with the FITS files of pure emission line spectra (i.e. the observed spectra after subtraction of the best-fitting synthetic stellar spectrum). Our results yield a good qualitative and quantitative agreement with previous studies based on the Sloan Digital Sky Survey (SDSS). However, an advantage of 6dF spectra is that they are taken within a twice as large fiber aperture, much reducing aperture effects in studies of nearby dwarf galaxies.

BATCH COMPRESSION TO 50 NS SPACING AT PS FLAT-TOP
Creators: name: Damerau, Heiko
Publisher: name: CERN Proceedings
Year: 2019

description: The bunch spacing in the injector chain has a direct impact on the total number of bunches in the LHC and hence on its integrated luminosity. The baseline scheme for lead ion beams within the LHC Injector Upgrade (LIU) project fore- sees the transfer of multiple batches of four bunches spaced by 100 ns from the PS to the SPS. The bunch spacing will then be reduced by momentum slip-stacking from 100 ns to 50 ns. Studies have been performed in view of alternatively producing 50 ns spacing directly at extraction from the PS, with the aim of demonstrating a batch compression-like RF manipulation to approach two bunches. Additionally, the proof-of principle tests allow to define the requirements for an additional RF system in the PS for the batch compression of four bunches to 50 ns spacing. Together with slip stacking in the SPS, this scheme would yield 25 ns bunch spacing with ions in the LHC.

description: The formation of liquid bridges between a planar and conical substrates is analyzed macroscopically taking into account the line tension. Depending on the value of the line tension coefficient τ and geometric parameters of the system one observes two different scenarios of liquid bridge formation upon changing the fluid state along the bulk liquid-vapor coexistence. For τ> τ* (τ* < 0) there is a first-order transition to a state with infinitely thick liquid bridge. For τ< τ* the scenario consists of two steps: first there is a first-order transition to a state with liquid bridge of finite thickness which upon further increase of temperature is followed by continuous growth of the thickness of the bridge to infinity. In addition to constructing the relevant phase diagram we examine the dependence of the width of the bridge on thermodynamic and geometric parameters of the system.

description: We consider the problem of estimating the relationship between a response variable and a set of explanatory variates. We suppose a set of parametric forms as candidates for the aforementioned regression. Wavelet regression is used as auxiliary for the choice of the most appropriate parametric form of the model, particularly for the cases of nonlinear and generalized linear models. The use of a wavelet method for the choice of the most appropriate parametric relationship is interesting in practice for four main reasons. The first is that it provides a statistically sound method to choose the ’best’ parametric model for a data set, given that no pre-determined regression form nor probability distribution are assumed to be known. On the other hand, the parametric models are easier to interpret and more convenient for prediction purposes than non-parametric ones. Moreover, since wavelet methods possess a natural data-driven shrinkage paradigm, we can ascertain that overfitting is not expected. For instance, the results show that few non-null coefficients remain after thresholding. Finally, fast wavelet methods are widely available which makes this a feasible procedure for researchers as well as data analysts. We evaluate the performance of the proposed wavelet procedure based on the correct classification rates of the underlying parametric form on a range of candidate models, taking into account a wide range of scenarios. The method is also illustrated by real data analyses. Computer codes are available as supplementary material.

description: We constrain the chameleonic Sunyaev--Zel'dovich (CSZ) effect in the Coma cluster from measurements of the Coma radial profile presented in the WMAP 7-year results. The CSZ effect arises from the interaction of a scalar (or pseudoscalar) particle with the cosmic microwave background in the magnetic field of galaxy clusters. We combine this radial profile data with SZ measurements towards the centre of the Coma cluster in different frequency bands, to find Delta T_{SZ,RJ}(0)=-400+/-40 microKelvin and Delta T_{CSZ}^{204 GHz}(0)=-20+/-15 microKelvin (68% CL) for the thermal SZ and CSZ effects in the cluster respectively. The central value leads to an estimate of the photon to scalar (or pseudoscalar) coupling strength of g = (5.2 - 23.8) x 10^{-10} GeV^{-1}, while the 95% confidence bound is estimated to be g < (8.7 - 39.4) x 10^{-10} GeV^{-1}.

description: We consider the complex data modeling problem motivated by the zero-inflated and overdispersed data from microbiome studies. Analyzing how microbiome abundance is associated with human biological features, such as BMI, is of great importance for host health. Methods based on parametric distributional assumptions, such as zero-inflated Poisson and zero-inflated Negative Binomial regression, have been widely used in modeling such data, yet the parametric assumptions are restricted and hard to verify in real-world applications. We relax the parametric assumptions and propose a semiparametric single-index quantile regression model. It is flexible to include a wide range of possible association functions and adaptable to the various zero proportions across subjects, which relaxes the strong parametric distributional assumptions of most existing zero-inflated data modeling approaches. We establish the asymptotic properties for the index coefficients estimator and quantile regression curve estimation. Through extensive simulation studies, we demonstrate the superior performance of the proposed method regarding model fitting.
title: Dynamic variations in anthropogenic heat flux: a model and its implications
Creators: name: Capel-Timms, Isabella
Publisher: name: University of Reading
Year: 2023

description: Recent advances in urban climate modelling and weather forecasting have allowed for the integration of multiple processes at fine resolutions. Anthropogenic heat flux (QF) is the thermal emission due to human activity and is therefore most relevant in urban areas. It can impact aspects of urban meteorology through the modification of other surface energy balance fluxes. Despite this, QF is often underrepresented in forecasting and urban land surface studies. Whilst current modelling approaches provide reasonable estimates, they do not have the capability for detailed scenario modelling. This thesis presents a novel, agent-based QF modelling approach (Dynamic Anthropogenic activitieS impacting Heat emissions – DASH) with human behaviours governing its fundamental dynamics, integrating simple building energy and transport models. This model can be used to investigate a city’s response to scenarios such as population growth or climate change. To facilitate inclusion with broader urban land surface studies and weather models, DASH is adapted to two more computationally efficient schemes in such a way that spatial, temporal and thermal response behaviours are still represented. DASH is also coupled to an urban land surface model, SUEWS, to allow for feedback with the outdoor environment, e.g. temperature response. DASH is developed for Greater London for October 2014 – September 2015 at a local resolution. It is evaluated against both an existing model and energy statistics for the same area and period. Expected diurnal, weekly and seasonal patterns are observed, along with variations due to building use and demographics. Areally weighted mean annual QF is 6.43 W m-2 in the evaluated instance, and 8.47 W m-2 when coupled to SUEWS (under different forcing meteorology). The two more efficient schemes, with parameters derived from DASH, show means of 6.68 and 7.44 W m-2 , but broader distributions overall.

description: This study was aim to examine the cognitive progress of graphic design involved in concept development. The results show that: (1) Cognitive progress can be observed from the design thinking and drawing patterns that emerge in designing works. The thinking activity was distinguished into general, experiential and evaluating thoughts, whereas drawing activity was categorized into graphic drawing and word description. (2) On the whole, more time was spent on general thought, less on experiential thought, and the least on evaluating thought. (3) There were three stages of concept development. General thought occurs more frequent in the initial stage while picture sketch takes place more frequent in the middle and final stages. In the other words, the process of the concept development was filled up via the concepts formed at first stage and translated into idea sketches at the next two stages.

description: Using an effective interaction approach to describe the interactions between the dark matter particle and the light degrees of freedom of the standard model, we calculate the antiproton flux due to the annihilation of the dark matter in the Galactic Halo and compare to the most recent antiproton spectrum of the PAMELA experiment. We obtain useful constraints on the size of the effective interactions that are comparable to those deduced from collider and gamma-ray experiments.

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The supercurrent for the surface superconductivity of a flat-band multilayered rhombohedral graphene is calculated. Despite the absence of dispersion of the excitation spectrum, the supercurrent is finite. The critical current is proportional to the zero-temperature superconducting gap, i.e., to the superconducting critical temperature and to the size of the flat band in the momentum space.

description: Ultrasonic pretreatment could improve the accessibility of enzymes to cellulosic fibers, hence expanding the access of enzymes to effectively remove ink from paper. In this study, enzymes were isolated from paddy rice husks and utilized for biodeinking process. The characterizations of deinking from the pulp filtrate and paper samples were carried out to understand the effect of bacterial cellulases and ultrasonic pretreatment with time variables. The results showed that cellulases from bacterial isolates had the ability to hydrolyze cellulose at 1.78 U/mL enzyme activity. Ink content measurement showed 2310 ppm of ink was removed in the paper samples with 15 min of ultrasound pretreatment and 2% cellulases. Meanwhile, morphological analysis showed significant differences in the surface areas between treated and untreated paper samples. The highest crystallinity index achieved was 70.9%, and thermal resistance was 21.0%. Other paper qualities such as stain decrease, and brightness level improvement were observed. The combination of 2% cellulases with optimum ultrasonication duration resulted in exceptional wastepaper recycling process.

description: On 2009 July 19, we observed a single, large impact on Jupiter at a planetocentric latitude of 55^{\circ}S. This and the Shoemaker-Levy 9 (SL9) impacts on Jupiter in 1994 are the only planetary-scale impacts ever observed. The 2009 impact had an entry trajectory opposite and with a lower incidence angle than that of SL9. Comparison of the initial aerosol cloud debris properties, spanning 4,800 km east-west and 2,500 km north-south, with those produced by the SL9 fragments, and dynamical calculations of pre-impact orbit, indicate that the impactor was most probably an icy body with a size of 0.5-1 km. The collision rate of events of this magnitude may be five to ten times more frequent than previously thought. The search for unpredicted impacts, such as the current one, could be best performed in 890-nm and K (2.03-2.36 μm) filters in strong gaseous absorption, where the high-altitude aerosols are more reflective than Jupiter's primary cloud.

description: Accurate glucose forecasting algorithms have been proven to be an effective solution for reducing the risk of hypo- and hyperglycaemia events when combined with glucose alarms and/or low-insulin suspension systems. • Effective glucose forecasting algorithm can be applied to control insulin delivery in automatic systems. • Daily routine information (e.g. meal intake, insulin injection, physical exercises) of patient can be included into forecasting algorithms to improve prediction accuracy. • In this work, we introduce a novel model-based glucose prediction algorithm which uses deconvolution of the continuous glucose monitoring (CGM) signal to estimate some of the model states in order to improve prediction accuracy.

description: We analyze the ground states and the elementary collective excitations (phonons) of a class of systems, which form cluster crystals in the absence of attractions. Whereas the regime of moderate-to-high-temperatures in the phase diagram has been analyzed in detail by means of density functional considerations (Likos C N, Mladek B M, Gottwald D and Kahl G 2007 {\it J.~Chem.~Phys.}\ {\bf 126} 224502), the present approach focuses on the complementary regime of low temperatures. We establish the existence of an infinite cascade of isostructural transitions between crystals with different lattice site occupancy at $T=0$ and we quantitatively demonstrate that the thermodynamic instabilities are bracketed by mechanical instabilities arising from long-wavelength acoustical phonons. We further show that all optical modes are degenerate and flat, giving rise to perfect realizations of Einstein crystals. We calculate analytically the complete phonon spectrum for the whole class of models as well as the Helmholtz free energy of the systems. On the basis of the latter, we demonstrate that the aforementioned isostructural phase transitions must terminate at an infinity of critical points at low temperatures, brought about by the anharmonic contributions in the Hamiltonian and the hopping events in the crystals.
