description: Diphenyl phosphate (DPP) was exploited as an organocatalyst to synthesize copolymers by ring-opening polymerization with α-bromo-γ-butyrolactone (αBrγBL) and ε-caprolactone (εCL) as monomers and polyethylene glycol (PEG) as initiator. The conversion rates of monomers and molecular weights of copolymers synthesized under different conditions were determined by 1H-NMR. The 1H-NMR results showed that the copolymers of αBrγBL and εCL initiated by PEG (PEGCB) were successfully synthesized and the conversions of εCL were relatively high (＞70%), while the conversions of αBrγBL were relatively low (＜26%). The highest molar ratio of αBrγBL to εCL units in these copolymers is 0.17, when the copolymerization was carried out at 100℃ for 17h. The bromine atoms hanged on the chain of the copolymers PEGCB provide a good opportunity to construct graft copolymers via atom transfer radical polymerization (ATRP). The subsequent grafting of 2-(dimethylamino)ethyl methacrylate (DMAEMA) was conducted by using PEGCB3 as macroinitiator, CuBr/N,N’,N’,N”,N”- pentamethyldiethylenetriamine (PMDETA) as catalysts and toluene/anisole as solvents via ATRP. According to the analysis of 1H-NMR, the grafting efficiency, grafting ratio and grafting frequency were 22.4%, 160.7% and 1133.8, respectively.

Combined with known results on optimal LCD code, $d_{l}(n,5)$ of all $[n,5]$ LCD codes are completely determined.

description: We investigate the propagation of accretion-powered jets in various types of massive stars such as Wolf-Rayet stars, light Population III (Pop III) stars, and massive Pop III stars, all of which are the progenitor candidates of Gamma-Ray Bursts (GRBs). We perform two dimensional axisymmetric simulations of relativistic hydrodynamics taking into account both the envelope collapse and the jet propagation (i.e., the negative feedback of the jet on the accretion). Based on our hydrodynamic simulations, we show for the first time that the accretion-powered jet can potentially break out relativistically from the outer layers of Pop III progenitors. In our simulations, the accretion rate is estimated by the mass flux going through the inner boundary, and the jet is injected with a fixed accretion-to-jet conversion efficiency $η$. By varying the efficiency $η$ and opening angle $θ_{op}$ for more than 40 models, we find that the jet can make a relativistic breakout from all types of progenitors for GRBs if a simple condition $η\gtrsim 10^{-4} (θ_{op}/8^{\circ})^2$ is satisfied, which is consistent with analytical estimates. Otherwise no explosion or some failed spherical explosions occur.

description: The investigation of luminal factors influencing zinc availability and accessibility in the intestine is of great interest when analyzing parameters regulating intestinal zinc resorption. Of note, intestinal mucins were suggested to play a beneficial role in the luminal availability of zinc. Their exact zinc binding properties, however, remain unknown and the impact of these glycoproteins on human intestinal zinc resorption has not been investigated in detail. Thus, the aim of this study is to elucidate the impact of intestinal mucins on luminal uptake of zinc into enterocytes and its transfer into the blood. In the present study, in vitro zinc binding properties of mucins were analyzed using commercially available porcine mucins and secreted mucins of the goblet cell line HT-29-MTX. The molecular zinc binding capacity and average zinc binding affinity of these glycoproteins demonstrates that mucins contain multiple zinc-binding sites with biologically relevant affinity within one mucin molecule. Zinc uptake into the enterocyte cell line Caco-2 was impaired by zinc-depleted mucins. Yet this does not represent their form in the intestinal lumen in vivo under zinc adequate conditions. In fact, zinc-uptake studies into enterocytes in the presence of mucins with differing degree of zinc saturation revealed zinc buffering by these glycoproteins, indicating that mucin-bound zinc is still available for the cells. Finally, the impact of mucins on zinc resorption using three-dimensional cultures was studied comparing the zinc transfer of a Caco-2/HT-29-MTX co-culture and conventional Caco-2 monoculture. Here, the mucin secreting co-cultures yielded higher fractional zinc resorption and elevated zinc transport rates, suggesting that intestinal mucins facilitate the zinc uptake into enterocytes and act as a zinc delivery system for the intestinal epithelium.

These invariants may depend on unrestricted chiral supermultiplets, on vector supermultiplets and on the Weyl supermultiplet. Supersymmetry is realized off-shell. A non-renormalization theorem is proven according to which none of these invariants can contribute to the entropy and electric charges of BPS black holes. Some of these invariants may be relevant for topological string deformations.

description: Recent genomic evidence suggest that kea (Nestor notabilis) have a non-functional RH2 opsin gene potentially leading to impaired vision in the green region of the electromagnetic spectrum. In New Zealand, it is standard procedure to add green dye to aerial poison baits used in mammalian predator control operations to deter native birds from eating toxic bait. A visual deficiency could impact how kea perceive and interact with green-dyed baits and thus have unforeseen consequences for kea conservation. Here, we sequenced the partial RH2 gene of seven wild kea and re-analysed the kea genome raw sequencing data of the RH2 locus. We demonstrate that the reported premature stop codon is most likely an assembly artefact. An extended analysis of the published genomes of all three extant New Zealand parrots of the superfamily Strigopoidea confirms that the RH2 gene is functional in this entire group.

description: In intensive care units (ICUs), critically ill patients are monitored with electroencephalograms (EEGs) to prevent serious brain injury. The number of patients who can be monitored is constrained by the availability of trained physicians to read EEGs, and EEG interpretation can be subjective and prone to inter-observer variability. Automated deep learning systems for EEG could reduce human bias and accelerate the diagnostic process. However, black box deep learning models are untrustworthy, difficult to troubleshoot, and lack accountability in real-world applications, leading to a lack of trust and adoption by clinicians. To address these challenges, we propose a novel interpretable deep learning model that not only predicts the presence of harmful brainwave patterns but also provides high-quality case-based explanations of its decisions. Our model performs better than the corresponding black box model, despite being constrained to be interpretable. The learned 2D embedded space provides the first global overview of the structure of ictal-interictal-injury continuum brainwave patterns. The ability to understand how our model arrived at its decisions will not only help clinicians to diagnose and treat harmful brain activities more accurately but also increase their trust and adoption of machine learning models in clinical practice; this could be an integral component of the ICU neurologists' standard workflow.

Evaluating biosimilars uptake and policy in Canada
Creators: name: McClean, Alison
Publisher: name: University of British Columbia
Year: 2023

description: BACKGROUND Despite representing less than 2% of prescriptions, biologics accounted for nearly three of every ten dollars spent on prescribed medicines in Canada in 2018. Similar to generics for small molecule drugs, biologic biosimilars are one potential way in which payers can reduce drug spending. In 2019, the government of British Columbia became the first in North America to mandate switching from reference biologics to biosimilars. While a number of other provinces have followed, the impact of these policies remains unclear. Therefore, this thesis examined the current state of biosimilars use in Canada. METHODS This dissertation focused on uptake of and spending on infliximab, etanercept, and insulin glargine using two primary data sources: (1) data from the IQVIA Canadian Drugstore and Hospital Purchases Audit representing all Canadian provinces except Newfoundland and Labrador, and (2) British Columbia health administrative data from Population Data BC. Interrupted time series analysis was used to quantify the results of two eras of biosimilars policies in British Columbia, including mandatory biosimilars use for new starters and subsequently mandated switching for all users, among individuals with inflammatory arthritis and psoriasis. RESULTS We found that prior to 2019 uptake of biosimilar infliximab, etanercept, and insulin glargine was low across Canada. Coinciding with the introduction of mandatory switching policies, there was a large increase in utilization thereafter in a number of provinces. In British Columbia, we determined that the introduction of mandatory switching among individuals with inflammatory arthritis and diabetes mellitus resulted in an increase in biosimilars utilization beyond what would have occurred if payers maintained new start policies only. CONCLUSION Government-mandated switching policies have the ability to greatly increase use of biosimilars even in the context of a multi-payer system. Although the ability to ascertain savings is limited due to the proprietary nature of drug pricing in Canada, the enhanced use of biosimilars will likely create a more favorable environment for price-based competition among pharmaceutical manufacturers. Future work should continue to examine the impact of mandatory switching on patients and prescribers as well as on the market for biologic drugs on a longer time horizon.

description: The investigation of topological state transition in carefully designed photonic lattices is of high interest for fundamental research, as well as for applied studies such as manipulating light flow in on-chip photonic systems. Here, we report on topological phase transition between symmetric topological zero modes (TZM) and antisymmetric TZMs in Su-Schrieffer-Heeger (SSH) mirror symmetric waveguides. The transition of TZMs is realized by adjusting the coupling ratio between neighboring waveguide pairs, which is enabled by selective modulation of the refractive index in the waveguide gaps. Bi-directional topological transitions between symmetric and antisymmetric TZMs can be achieved with our proposed switching strategy. Selective excitation of topological edge mode is demonstrated owing to the symmetry characteristics of the TZMs. The flexible manipulation of topological states is promising for on-chip light flow control and may spark further investigations on symmetric/antisymmetric TZM transitions in other photonic topological frameworks.

description: We have developed a general formalism to compute Sommerfeld enhancement (SE) factors for a multi-state system of fermions, in all possible spin configurations and with generic long-range interactions. We show how to include such SE effects in an accurate calculation of the thermal relic density for WIMP dark matter candidates. We apply the method to the MSSM and perform a numerical study of the relic abundance of neutralinos with arbitrary composition and including the SE due to the exchange of the W and Z bosons, photons and Higgses. We find that the relic density can be suppressed by a factor of a few in a seizable region of the parameter space, mostly for Wino-like neutralino with mass of a few TeV, and up to an order of magnitude close to a resonance.

description: The phenomena of collapse and dispersal for a massless scalar field has drawn considerable interest in recent years, mainly from a numerical perspective. We give here a sufficient condition for the dispersal to take place for a scalar field that initially begins with a collapse. It is shown that the change of the gradient of the scalar field from a timelike to a spacelike vector must be necessarily accompanied by the dispersal of the scalar field. This result holds independently of any symmetries of the spacetime. We demonstrate the result explicitly by means of an example, which is the scalar field solution given by Roberts. The implications of the result are discussed.

description: Characters in educational videos have been shown to help children learn and transfer knowledge. The aim of this study is to explore the influence of realism and familiarity of characters on children’s video learning. The participants were 90 4- to 6-year-olds. The children watched a video in which a character demonstrated how to construct simple gears, and then completed the same task to test the effect of the character’s realism and familiarity on their learning and transfer of STEM knowledge. A 2 (high-reality vs. low-reality) × 2 (familiar, unfamiliar) experiment was adopted. The results showed that children learned STEM material better from live-action human characters than from animated animal characters. However, the familiarity of the character did not influence children’s learning, and the parasocial relationship between children and the character also did not improve learning. The findings suggest that the realism of the characters, not their familiarity, is key in helping children learn from educational videos. Prior State of Knowledge: Children’s learning from screen-based educational media can be influenced by characteristics of the characters. Less is known about whether realistic and familiar characteristics improve children’s screen learning. Novel Contributions: We created four characters based on combined realism and familiarity to explore whether some characters are better than others at promoting learning STEM information. Practical Implications: Our findings are relevant to producers of educational videos. Compared to animated characters, live-action human characters may better help children ages 4 to 6 years to learn from these videos.

description: We consider the problem of learning causal information between random variables in directed acyclic graphs (DAGs) when allowing arbitrarily many latent and selection variables. The FCI (Fast Causal Inference) algorithm has been explicitly designed to infer conditional independence and causal information in such settings. However, FCI is computationally infeasible for large graphs. We therefore propose the new RFCI algorithm, which is much faster than FCI. In some situations the output of RFCI is slightly less informative, in particular with respect to conditional independence information. However, we prove that any causal information in the output of RFCI is correct in the asymptotic limit. We also define a class of graphs on which the outputs of FCI and RFCI are identical. We prove consistency of FCI and RFCI in sparse high-dimensional settings, and demonstrate in simulations that the estimation performances of the algorithms are very similar. All software is implemented in the R-package pcalg.

description: The logarithmic broadening predicted by the systematic low-energy effective field theory for the confining string has recently been verified in numerical simulations of (2+1)-d SU(2) lattice Yang-Mills theory at zero temperature. The same effective theory predicts linear broadening of the string at low non-zero temperature. In this paper, we verify this prediction by comparison with very precise Monte Carlo data. The comparison involves no additional adjustable parameters, because the low-energy constants of the effective theory have already been fixed at zero temperature. It yields very good agreement between the underlying Yang-Mills theory and the effective string theory.

description: There is a great need for the replication of evidenced-based teen pregnancy prevention curriculums. Minority youth, living in impoverished areas are underserved and at greater risk of teen pregnancy. Research on empirically supported curriculums shows promise for effectively reducing risk behaviors among youth, but less is known about the effectiveness of these curriculums when adapted and delivered in community settings.

The objectives were:
1. The primary objective was to investigate the challenges in adapting an evidence-based curriculum into community settings in Tulsa, OK during the first year of grant funding.
2.The secondary objective was to evaluate the efficacy of the adapted curriculum as delivered by community-based group leaders (Bryan et al., 2009).

description: In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images' discovery, the SN was predicted to reappear within hundreds of days at a new position ~8 arcseconds away in the field. The observed reappearance in late 2015 makes it possible to carry out Refsdal's (1964) original proposal to use a multiply imaged SN to measure the Hubble constant H0, since the time delay between appearances should vary inversely with H0. Moreover, the position, brightness, and timing of the reappearance enable a novel test of the blind predictions of galaxy-cluster models, which are typically constrained only by the positions of multiply imaged galaxies. We have developed a new photometry pipeline that uses DOLPHOT to measure the fluxes of the five images of SN Refsdal from difference images. We apply four separate techniques to perform a blind measurement of the relative time delays and magnification ratios (mu_i/mu_1) between the last image SX and the earlier images S1-S4. We measure the relative time delay of SX-S1 to be 376.0+5.6-5.5 days and the relative magnification to be 0.30+0.05-0.03. This corresponds to a 1.5% precision on the time delay and 17% precision for the magnification ratios, and includes uncertainties due to millilensing and microlensing. In an accompanying paper, we place initial and blind constraints on the value of the Hubble constant.

description: This paper realizes of two families of combinatorial symmetric functions via the complex character theory of the finite general linear group $\mathrm{GL}_{n}(\mathbb{F}_{q})$: chromatic quasisymmetric functions and vertical strip LLT polynomials. The associated $\mathrm{GL}_{n}(\mathbb{F}_{q})$ characters are elementary in nature and can be obtained by induction from certain well-behaved characters of the unipotent upper triangular groups $\mathrm{UT}_{n}(\mathbb{F}_{q})$. The proof of these results also gives a general Hopf algebraic approach to computing the induction map. Additional results include a connection between the relevant $\mathrm{GL}_{n}(\mathbb{F}_{q})$ characters and Hessenberg varieties and a re-interpretation of known theorems and conjectures about the relevant symmetric functions in terms of $\mathrm{GL}_{n}(\mathbb{F}_{q})$.

description: We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable double well potential on an atom chip. Matter wave interferometry gives direct access to the relative phase field, which reflects the interplay of thermally driven fluctuations and phase locking due to tunneling. The thermal equilibrium state is characterized by probing the full statistical distribution function of the two-point phase correlation. Comparison to a stochastic model allows to measure the coupling strength and temperature and hence a full characterization of the system.
Pedestrian intent estimation through visual attention and time and memory conscious u-shaped networks for training neural radiance fields

description: When people cross the street, they make a series of movements that are indicative of their attention, intention, and comprehension of the roadside environment. These patterns in attention are linked to individual characteristics which are often neglected by autonomous vehicle prediction algorithms. We make two strides towards more personalized pedestrian modelling. First, we design an outdoor data study to collect behavioural signals such as pupil, gaze, head, and body orientation from an ego-centric human point of view. We gather this data over a range of diverse variables including age, gender, geographical context, crossing type, time of day, and the presence of a companion. In order for simulation engines to be able to leverage such dense data, efficient 3D human and scene reconstruction algorithms must be available. The increased resolution and model-free nature of Neural Radiance Fields for large scene reconstruction and human motion synthesis come at the cost of high training times and excessive memory requirements. Little has been done to reduce the resources required at training time in a manner that supports both dynamic and static tasks. Our second contribution takes the form of an efficient method which provides a reduction of the memory footprint, improved accuracy, and reduced amortized processing time both during training and inference. We demonstrate that the conscious separation of view-dependent appearance and view-independent density estimation improves novel view synthesis of static scenes as well as dynamic human shape and motion. Further, we show that our method, UNeRF, can be used to augment other state-of-the-art reconstruction techniques to further accelerate and enhance the improvements which they present.

description: Compressive sensing (CS) exploits the sparsity present in many signals to reduce the number of measurements needed for digital acquisition. With this reduction would come, in theory, commensurate reductions in the size, weight, power consumption, and/or monetary cost of both signal sensors and any associated communication links. This paper examines the use of CS in the design of a wideband radio receiver in a noisy environment. We formulate the problem statement for such a receiver and establish a reasonable set of requirements that a receiver should meet to be practically useful. We then evaluate the performance of a CS-based receiver in two ways: via a theoretical analysis of its expected performance, with a particular emphasis on noise and dynamic range, and via simulations that compare the CS receiver against the performance expected from a conventional implementation. On the one hand, we show that CS-based systems that aim to reduce the number of acquired measurements are somewhat sensitive to signal noise, exhibiting a 3dB SNR loss per octave of subsampling, which parallels the classic noise-folding phenomenon. On the other hand, we demonstrate that since they sample at a lower rate, CS-based systems can potentially attain a significantly larger dynamic range. Hence, we conclude that while a CS-based system has inherent limitations that do impose some restrictions on its potential applications, it also has attributes that make it highly desirable in a number of important practical settings.

description: We measure the axisymmetric transport of magnetic flux on the Sun by cross-correlating narrow strips of data from line-of-sight magnetograms obtained at a 96-minute cadence by the MDI instrument on the ESA/NASA SOHO spacecraft and then averaging the flow measurements over each synodic rotation of the Sun. Our measurements indicate that the axisymmetric flows vary systematically over the solar cycle. The differential rotation is weaker at maximum than at minimum. The meridional flow is faster at minimum and slower at maximum. The meridional flow speed on the approach to the Cycle 23/24 minimum was substantially faster than it was at the Cycle 22/23 minimum. The average latitudinal profile is largely a simple sinusoid that extends to the poles and peaks at about $35\degr$ latitude. As the cycle progresses a pattern of in-flows toward the sunspot zones develops and moves equatorward in step with the sunspot zones. These in-flows are accompanied by the torsional oscillations. This association is consistent with the effects of the Coriolis force acting on the in-flows. The equatorward motions associated with these in-flows are identified as the source of the decrease in net poleward flow at cycle maxima. We also find polar counter-cells (equatorward flow at high latitudes) in the south from 1996 to 2000 and in the north from 2002 to 2010. We show that these measurements of the flows are not affected by the non-axisymmetric diffusive motions produced by supergranulation.

Proper local scoring rules on discrete sample spaces

description: A scoring rule is a loss function measuring the quality of a quoted probability distribution $Q$ for a random variable $X$, in the light of the realized outcome $x$ of $X$; it is proper if the expected score, under any distribution $P$ for $X$, is minimized by quoting $Q=P$. Using the fact that any differentiable proper scoring rule on a finite sample space ${\mathcal{X}}$ is the gradient of a concave homogeneous function, we consider when such a rule can be local in the sense of depending only on the probabilities quoted for points in a nominated neighborhood of $x$. Under mild conditions, we characterize such a proper local scoring rule in terms of a collection of homogeneous functions on the cliques of an undirected graph on the space ${\mathcal{X}}$. A useful property of such rules is that the quoted distribution $Q$ need only be known up to a scale factor. Examples of the use of such scoring rules include Besag's pseudo-likelihood and Hyvärinen's method of ratio matching.

Van der Waals interaction between an atom with spherical plasma shell

description: We consider the van der Waals energy of an atom near the infinitely thin sphere with finite conductivity which model the fullerene. We put the sphere into spherical cavity inside the infinite dielectric media, then calculate the energy of vacuum fluctuations in framework of the zeta-function approach. The energy for a single atom is obtained from this expression by consideration of the rare media. In the limit of the infinite radius of the sphere the Casimir-Polder expression for an atom and plate is recovered. For finite radius of sphere the energy of an atom monotonously falls down as $d^{-3}$ close to the sphere and $d^{-7}$ far from the sphere. For hydrogen atom on the surface of the fullerene $C_{60}$ we obtain that the energy is $3.8 eV$. We obtain also that the polarizability of fullerene is merely cube of its radius.

description: For carbon-oxygen white dwarfs accreting hydrogen or helium at rates in the range ~1-10 x 10^(-8) Msun/y, a variety of explosive outcomes is possible well before the star reaches the Chandrasekhar mass. These outcomes are surveyed for a range of white dwarf masses (0.7 - 1.1 Msun), accretion rates (1 - 7 x 10^(-8) Msun/y), and initial white dwarf temperatures (0.01 and 1 Lsun). The results are particularly sensitive to the convection that goes on during the last few minutes before the explosion. Unless this convection maintains a shallow temperature gradient, and unless the density is sufficiently high, the accreted helium does not detonate. Below a critical helium ignition density, which we estimate to be 5 - 10 x 10^5 g cm^(-3), either helium novae or helium deflagrations result. The hydrodynamics, nucleosynthesis, light curves, and spectra of a representative sample of detonating and deflagrating models are explored. Some can be quite faint indeed, powered at peak for a few days by the decay of 48Cr and 48V. Only the hottest, most massive white dwarfs considered with the smallest helium layers, show reasonable agreement with the light curves and spectra of common Type Ia supernovae. For the other models, especially those involving lighter white dwarfs, the helium shell mass exceeds 0.05 Msun and the mass of the 56Ni that is synthesized exceeds 0.01 Msun. These explosions do not look like ordinary Type Ia supernovae, or any other frequently observed transient.

description: Short-duration noise transients in LIGO and Virgo detectors significantly affect the search sensitivity of compact binary coalescence (CBC) signals, especially in the high mass region. In a previous work by the authors \cite{Joshi_2021}, a $χ^2$ statistic was proposed to distinguish them, when modeled as sine-Gaussians, from non-spinning CBCs. The present work is an extension where we demonstrate the better noise-discrimination of an improved $χ^2$ statistic -- called the optimized sine-Gaussian $χ^2$ -- in real LIGO data. The extension includes accounting for the initial phase of the noise transients and use of a well-informed choice of sine-Gaussian basis vectors selected to discern how CBC signals and some of the most worrisome noise-transients project differently on them~\cite{sunil_2022}. To demonstrate this improvement, we use data with blip glitches from the third observational run (O3) of LIGO-Hanford and LIGO-Livingston detectors. Blips are a type of short-duration non-Gaussian noise disturbance known to adversely affect high-mass CBC searches. For CBCs, spin-aligned binary black hole signals were simulated using the \textsc{IMRPhenomPv2} waveform and injected into real LIGO data from the same run. We show that in comparison to the sine-Gaussian $χ^2$, the optimized sine-Gaussian $χ^2$ improves the overall true positive rate by around 6\% in a lower-mass bin ($m_1,m_2 \in [20,40]M_{\odot}$) and by more than 3\% in a higher-mass bin ($m_1,m_2 \in [60,80]M_{\odot}$). On the other hand, we see a larger improvement -- of more than 20\% -- in both mass bins in comparison to the traditional $χ^2$.

description: We formulate a linear response theory of the spin Seebeck effect, i.e., a spin voltage generation from heat current flowing in a ferromagnet. Our approach focuses on the collective magnetic excitation of spins, i.e., magnons. We show that the linear-response formulation provides us with a qualitative as well as quantitative understanding of the spin Seebeck effect observed in a prototypical magnet, yttrium iron garnet.
