Aerodynamics of Kruger flap equipped airfoils
Creators: name: Thomson, Ken
Publisher: name: University of British Columbia
Year: 2009

description: The pressure distributions along two airfoil models of differing profiles equipped with upper surface Kruger flaps were measured. The results were compared with the predictions of a theoretical potential flow model, which used conformal mapping to bring the flapped airfoils into a final transform plane where the profile of the flapped airfoil was represented by a unit circle. Potential flow singularities such as sources, sinks, and doublets were added to the flow in the final transform plane to replicate the separation bubble created beneath the flap. Different arrangements of these singularities resulted in four different variations of the theoretical model. The model calculates the velocity and pressure distributions about the airfoil in the final transform plane, and then relays the information back to the original airfoil plane. As mentioned, the experimental investigations were conducted on two different airfoils, the NACA 0018 airfoil, and the FXL III 142 airfoil. Each clean airfoil model had a chord of 24 inches, spanned the 15 inch high test section, and was equipped with a removable 10% chord leading edge Kruger flap. The wind tunnel used had its side walls replaced with arrays of evenly spaced airfoil slats at zero incidence. The airfoil slatted walls resulted in a test section that needed little or no boundary corrections. Each airfoil was equipped with a row of pressure taps located at mid-span which allowed the local static pressure to be measured at various points along the chord. Agreement between experimental and theoretical results was poor at low angles of attack for all model variations, but became increasingly good as angle of attack increased, and as the influence of the separation bubble decreased. The model's accuracy reached a maximum in mid-range of angles of attack, from about 8° to 14°. In this range, the agreement along the suction side of the airfoils was excellent, and the agreement along the pressure side and bubble region was good for all four of the different models. As the angle of attack was increased to values near stall, non-linear and viscous effects became larger, and the models' accuracy decreased again. Methods of increasing the accuracy of the models were tried. Mapping an airfoil artificially augmented by the displacement thickness of a turbulent boundary layer was found to bring the experimental and theoretical results into almost perfect agreement along the suction surface of airfoils at mid-range angles of attack. Averaging the theoretical results for slightly different mapping functions was also found to remove some of the oscillations in the theoretical pressure distributions near the leading edge. , Although there were some problems at both the low and high angles of attack, the potential flow model successfully predicted the pressure distributions along airfoils equipped with upper surface Kruger flaps in the middle range of angles of attack, where the flaps are most likely to be deployed.

description: One of the symptoms of Parkinson's disease (PD) is hypomimia or reduced facial expressions. In this paper, we present a digital biomarker for PD that utilizes the study of micro-expressions. We analyzed the facial action units (AU) from 1812 videos of 604 individuals (61 with PD and 543 without PD, mean age 63.9 yo, sd 7.8 ) collected online using a web-based tool (www.parktest.net). In these videos, participants were asked to make three facial expressions (a smiling, disgusted, and surprised face) followed by a neutral face. Using techniques from computer vision and machine learning, we objectively measured the variance of the facial muscle movements and used it to distinguish between individuals with and without PD. The prediction accuracy using the facial micro-expressions was comparable to those methodologies that utilize motor symptoms. Logistic regression analysis revealed that participants with PD had less variance in AU6 (cheek raiser), AU12 (lip corner puller), and AU4 (brow lowerer) than non-PD individuals. An automated classifier using Support Vector Machine was trained on the variances and achieved 95.6% accuracy. Using facial expressions as a biomarker for PD could be potentially transformative for patients in need of physical separation (e.g., due to COVID) or are immobile.

Year: 2021

description: Purpose of ProjectUrine cultures are one of the most important lab tests utilized, in the work up of a urinary tract infection (UTI) amongst patients with neurological diseases. The purpose of this project was to assess the current practice of the use of urine cultures in this patient population to improve practice. MethodologyA retrospective chart review was conducted for patients in a Neuro-Oncology acute care unit. Participants included 53 patients over 60 days. Data was retrieved from the quality improvement (QI) department. Descriptive statistics were used to analyze the results of urine culture utilization. Results A total of 64 urine cultures were ordered from the 53-patient convenience sample over 60 days. Out of 64 urine cultures ordered, 70.3% (45) were negative, 18.8% (12) were positive and 10.9 % (7) were contaminated samples. There were 22.64% (12) of patients who had >1 urine culture ordered in one hospital stay. Of the 22.64%, there were 23 orders placed, which represents 35.94% of the total amount of urine cultures ordered. Patients w/ > or = 2 orders within 3 days or less represented 50% (6) of increased usage of urine cultures. ImplicationsMost Neuro-Oncology patients received a urine culture order, many times without checking for previous orders, as there were many repeated orders sent to the lab. The amount of negative urine culture orders compared to the amount positive indicates, that many patients might not need a urine culture during their hospital stay.

The Universal Identity Neural Network is an multidomain, cross-channel algorithmic knowledge graph providing persistent digital identity resolution, created through a unique set of Recurrent Neural Network (RNN) used to deterministically and probabilistically stitch real-time micro-moments information and customer data through a process called “Automated Algorithmic Identity Resolution or AAIR”.
A universal identification graph algorithm connects identities across computing devices and digital channels to one customer. The universal identification allow marketers to engage customers with relevant brand experience as they move between devices and across all digital channels. The universal identification graph algorithm enables mapping of a customer's journey across multiple, different identifications, allows deep personalization based on behaviors, habits, and preferences across the entire customer journey, helps create a more comprehensive customer profile to enable marketers to target the customer with relevant content at the right time and through the right channels, and also provides the customer with the ability to quickly opt out.

description: We apply the recently developed least squares stabilized symmetric Nitsche method for enforcement of Dirichlet boundary conditions to the finite cell method. The least squares stabilized Nitsche method in combination with finite cell stabilization leads to a symmetric positive definite stiffness matrix and relies only on elementwise stabilization, which does not lead to additional fill in. We prove a priori error estimates and bounds on the condition numbers.

description: Married women are more likely to leave careers and take on domestic labor responsibilities than their partners. This contributes to gender inequality in the workforce. The current investigation sought to understand this phenomenon by examining factors contributing to career and family planning in college-aged women. A novel Implicit Associations Test (IAT) examined the degree to which implicit self-concept explains variance beyond explicit measures of gender in willingness to compromise career for family, and chore division expectations. Eighty-six undergraduate women completed the IAT and a computer survey. Hierarchical multiple regression analyses found no relationship between the IAT and other variables. However, participants expected to perform more chores than ideally desired, and a positive relationship emerged between egalitarian gender role expectations and egalitarian ideal chore division. In post-hoc analyses, high expressivity related to egalitarian chore division expectations, and willingness to sacrifice career for children. Recommendations for future research and practice are discussed.

description: We derive a new twist-3 partonic sum rule for the transverse spin of the proton, which involves the well-know quark spin structure function $g_T(x)=g_1(x)+g_2(x)$, the less-studied but known transverse gluon polarization density $ΔG_T(x)$, and quark and gluon canonical orbital angular momentum densities associated with transverse polarization. This is the counter part of the sum rule for the longitudinal spin of the proton derived by Jaffe and Manohar previously. We relate the partonic canonical orbital angular momentum densities to a new class of twist-3 generalized parton distribution functions which are potentially measurable in deep-virtual exclusive processes. We also discuss in detail an important technicality related to the transverse polarization in the infinite momentum frame, i.e., separation of intrinsic contributions from the extrinsic ones. We apply our finding to the transverse-space distributions of partons, angular momentum, and magnetic moment, respectively, in a transversely polarized proton.

description: We propose the new concept of a switchable multimode microlaser. As a generic, realistic model of a multimode microresonator a system of two coupled defects in a two-dimensional photonic crystal is considered. We demonstrate theoretically that lasing of the cavity into one selected resonator mode can be caused by injecting an appropriate optical pulse at the onset of laser action (injection seeding). Temporal mode-to-mode switching by re-seeding the cavity after a short cool-down period is demonstrated by direct numerical solution. A qualitative analytical explanation of the mode switching in terms of the laser bistability is presented.

description: Tan Tans’ Garden is a research-based practice deeply rooted in the creation and dissection of a parafictional world. Tan Tans’ Garden is a metaphorical parallel universe birthed by the affects that American imperialism had on the Korean Peninsula, the Korean culture, and the Korean diaspora. In this paper, I discuss the creation of this world along with the studies of its landscape and its historical ecology from the perspective of a young millennial artist as well as a kin to generations of colonial trauma. The creative process manifests itself through critical analysis of histories and creative approaches to world-building, bookmaking, letter writing, collages, drawings, storytelling, object making, and video documentary. At the same time, the practice mutates itself into narratives of science-fiction and notions of post-humanism. Throughout this practice, I refer to the storytelling method in the context of geopolitics. I am heavily interested in how vulnerability, fermented memories—a term I will later explain—and the process of mourning can be utilized to explore the radiating violence of American imperialism. The works in Tan Tans’ Garden invite you to a fictional world in which the personal insights and intimate effects of being a byproduct of U.S. imperialism can be explored. This paper is sectioned by differing subject matter. The Key Terms are there to help guide you through the barriers of translation that I do not attempt to clarify or negotiate. Tan Tans’ Garden remains an ongoing practice and I am not seeking to find a pure conclusion to this work. Here, I am only trying to understand why it took so long for my grandparents to understand their own internalized trauma and memories, and why it took another 50 years to find words to their fermented memories. In this paper, I am only attempting to reiterate the stories that were told to me during the creation of this parafictional world. Here, the goal was to be vulnerable, without hindrance. Note: The collection of works and research findings presented in this paper were studied and created through the times of Covid-19. Having faced limitations to physical spaces of studio practice and research, these works were made in a personal household space. Initially what felt like a barrier ultimately became a realizing haven.

Athermal Jamming vs. glassy dynamics for particles with exponentially decaying repulsive pair interaction potentials with a cutoff
Creators: name: Wohlleben, Nicolas
name: Schmiedeberg, Michael
Publisher: name: arXiv
Year: 2020
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We study athermal jamming as well as the thermal glassy dynamics in systems composed of spheres that interact according to repulsive interactions that exponentially decay as a function of distance. As usual, a cutoff is employed in the simulations. While the athermal jamming transition that is determined by trying to remove overlaps is found to depend on the arbitrary and therefore unphysical choice of the cutoff, we do not find any athermal jamming transition or crossover that only relies on the physical decay length. In contrast, the glassy dynamics mainly depends on the decay length. Our findings constitute another demonstration of the fact that the athermal jamming transition is not related to thermal glassy dynamics. In addition, we argue that interactions without sharp physical cutoff should be considered more often as a model system in jamming. By exploring how widely-used theoretical approaches or methods of analysis in the field of jamming have to be changed in order to not depend on unphysical cutoffs will lead to deeper insights into the nature of athermal and thermal jamming.

description: We study the recognition capabilities of the Hopfield model with auxiliary hidden layers, which emerge naturally upon a Hubbard-Stratonovich transformation. We show that the recognition capabilities of such a model at zero-temperature outperform those of the original Hopfield model, due to a substantial increase of the storage capacity and the lack of a naturally defined basin of attraction. The modified model does not fall abruptly in a regime of complete confusion when memory load exceeds a sharp threshold.

 Description
 Adult males, SVL (snout vent length) = 29.85 – 43.45 mm; vomerine teeth present; mandibles with two prominent, sharply protruding bones; snout rounded; loreal region concave; nostrils closer to the tip of the snout than to the eyes; tympanum diameter (TY), 2 / to 3 / 5 5 of the eye diameter (EY) TY/EY = 0.473 – 0.694. Disk of finger small; the first finger reaches and exceeds the second finger; completely webbed toe, except on the fourth finger; subarticular tubercle developed; inner metatarsal present, elongated; length of tibia (TL) half or more of body length (TL/SVL = 0.569 – 0.659). Dorsal surface brown, black, reddish yellow; granular- ious, with small, even, smooth warts, following the body axis; there is a distinct fold above the tympanum; sometimes there is a yellowish-white line from the snout, or two lines from the back of the eyes, to the posterior end of the body; there are dark lines on the limbs.
 Habitat
 This species was often found close to the water flow, and at most 1 m away. It is sensitive to movement and light. During the survey, it was most active, making noise; however, when approached this species immediately stopped calling and hid. It was found in a variety of habitat types, such as leaf litter, grasses, herbaceous plant roots in the water flow, above the leaves in a puddle of water, fallen trees and branches. One specimen was collected from a rotten root with a horizontal and vertical distance from the water flow of 0.5 m. The noise it made sounded like the call of a bird and was distinct from that of the other individuals of this species. It was active at 20 – 25°C and 84 – 89% humidity.
 Remarks
 The species is widespread, occuring on Sulawesi, Peleng, Seram, Buru, Ambon, Obi, Bacan, Batudaka, Togian and Talatakoh, and Halmahera islands in Indonesia, up to 1200 m asl (IUCN 2017). It was the most common amphibian species observed in the Lake Kalimpa ’ a area, distributed throughout the observation plots at an elevation of 1650 – 1700 m asl, except for plot 8.

description: We introduce a new technique for the simulation of dissipative quantum systems. This method is composed of an approximate decomposition of the Lindblad equation into a Kraus map, from which one can define an ensemble of wavefunctions. Using principal component analysis, this ensemble can be truncated to a manageable size without sacrificing numerical accuracy. We term this method \emph{Ensemble Rank Truncation} (ERT), and find that in the regime of weak coupling, this method is able to outperform existing wavefunction Monte-Carlo methods by an order of magnitude in both accuracy and speed. We also explore the possibility of combining ERT with approximate techniques for simulating large systems (such as Matrix Product States (MPS)), and show that in many cases this approach will be more efficient than directly expressing the density matrix in its MPS form. We expect the ERT technique to be of practical interest when simulating dissipative systems for quantum information, metrology and thermodynamics.

description: Experiments in several intramolecular singlet fission materials have indicated that the triplet-triplet spin biexciton has a much longer lifetime than believed until recently, opening up loss mechanisms that can annihilate the biexciton prior to its dissociation to free triplets. We have performed many-body calculations of excited state wavefunctions of hypothetical phenylene-linked anthracene molecules to better understand linker-dependent behavior of dimers of larger acenes being investigated as potential singlet fission candidates. The calculations reveal unanticipated features that we show carry over to the real covalently-linked pentacene dimers. Dissociation of the correlated triplet-triplet spin biexciton and free triplet generation may be difficult in acene dimers where the formation of the triplet-triplet spin biexciton is truly ultrafast. Conversely, relatively slower biexciton formation may indicate smaller spin biexciton binding energy and greater yield of free triplets. Currently available experimental results appear to support this conclusion. Whether or not the two distinct behaviors are consequences of distinct mechanisms of triplet-triplet generation from the optical singlet is an interesting theoretical question.

description: The mixing between third and second (or first) generation squarks is very small in supersymmetric models with minimal flavor violation such as gauge-, anomaly- or gaugino-mediation. An opportunity to measure this mixing will arise if the lightest stop is close enough in mass to the lightest neutralino, so that the decays into third generation quarks are kinematically forbidden. We analyze under which circumstances it might become possible to measure at the Large Hadron Collider (LHC) the rate of the flavor changing stop decays.

description: The hereditary spastic paraplegias (HSPs) are genetic conditions in which there is progressive axonal degeneration in the corticospinal tract. Autosomal dominant mutations, including nonsense, frameshift and missense changes, in the gene encoding the microtubule severing ATPase spastin are the most common cause of HSP in North America and northern Europe. In this study we report quantitative gait analysis using a motorized treadmill system, carried out on mice knocked-in for a disease-associated mutation affecting a critical residue in the Walker A motif of the spastin ATPase domain. At 4 months and at one year of age homozygous mutant mice had a number of abnormal gait parameters, including in stride length and stride duration, compared to heterozygous and wild-type littermates. Gait parameters in heterozygous animals did not differ from wild-type littermates. We conclude that quantitative gait analysis using the DigiGait system sensitively detects motor abnormalities in a hereditary spastic paraplegia model, and would be a useful method for analyzing the effects of pharmacological treatments for HSP.

 Description
 Habit stout, SVL 56.05 – 72.65 mm; head wide (HW/SVL = 0.331 – 0.776) with a thick supraorbital; nostrils closer to the tip of the snout than to the eyes; vertical loreal region; large eyes (EY/SVL = 0.126); tympanum oval, distinct, 2 / 5 to 3 / 5 of the eye diameter (TY/ EY = 0.326 – 0.523). Disk of fingers and toes blunt; formula for the web of the toe, I 1 – 1 II 0 – 1 III 1 / 2 – 1 IV 1 – 0 V, follows that used by Savage and Heyer (1997); length of tibia, ratio of TL/SVL about 0.471 – 0.469; subarticular tubercles developed; inner metatarsal oval; smaller outer metatarsal. Dorsal surface is blackish; with scattered warts that have blackened ends; paratoid glands are very prominent, elongated; the venter part is pale yellow, granularious.
 Habitat
 An amplectant pair was found in plot 8 during the first survey, while it was raining. One juvenile was collected from plot 1 in the primary forest, 3 – 5 m distant from the flow. It was found to be active at 19 – 22°C and 84 – 99% humidity.
 Remarks
This species was found in primary forest (plot 1), open area (plot 8), and minimally disturbed primary forest (plot 9), at an elevation of 1700 m asl. The species has not previously been recorded higher than 1000 m asl (Leong and Chou 2000; Gillespie et al. 2004; Iskandar and Mumpuni 2004; Wanger et al. 2011). Of the three species of Bufonidae known from Sulawesi, only this species was recorded in our study. One individual was found with the third finger not having grown normally.

Dynamics and control of multibody tethered systems using an order-N formulation
Creators: name: Kalantzis, Spiros
Publisher: name: University of British Columbia
Year: 2009

description: The equations of motion for a multibody tethered satellite system in three dimensional Keplerian orbit are derived. The model considers a multi-satellite system connected in series by flexible tethers. Both tethers and subsatellites are free to undergo three dimensional attitude motion, together with deployment and retrieval as well as longitudinal and transverse vibration for the tether. The elastic deformations of the tethers are discretized using the assumed mode method. The tether attachment points to the subsatellites are kept arbitrary and time varying. The model is also capable of simulating the response of the entire system spinning about an arbitrary axis, as in the case of OEDIPUS-A/C which spins about the nominal tether length, or the proposed BICEPS mission where the system cartwheels about the orbit normal. The governing equations of motion are derived using a non-recursive order(N) Lagrangian procedure which significantly reduces the computational cost associated with the inversion of the mass matrix, an important consideration for multi-satellite systems. Also, a symbolic integration and coding package is used to evaluate modal integrals thus avoiding their costly on-line numerical evaluation. Next, versatility of the formulation is illustrated through its application to two different tethered satellite systems of contemporary interest. Finally, a thruster and momentum-wheel based attitude controller is developed using the Feedback Linearization Technique, in conjunction with an offset (tether attachment point) control strategy for the suppression of the tether's vibratory motion using the optimal Linear Quadratic Gaussian-Loop Transfer Recovery method. Both the controllers are successful in stabilizing the system over a range of mission profiles.

description: We consider the problem of the motion of $N$ bodies in a self-gravitating system in two spacetime dimensions. We point out that this system can be mapped onto the quantum-mechanical problem of an N-body generalization of the problem of the H$_{2}^{+}$ molecular ion in one dimension. The canonical gravitational N-body formalism can be extended to include electromagnetic charges. We derive a general algorithm for solving this problem, and show how it reduces to known results for the 2-body and 3-body systems.

description: Generating non-classical states in macroscopic systems is a long standing challenge. A promising platform in the context of this quest are novel hybrid systems based on magnetic dielectrics, where photons can couple strongly and coherently to magnetic excitations, although a non-classical state therein is yet to be observed. We propose a scheme to generate a magnetization cat state, i.e. a quantum superposition of two distinct magnetization directions, using a conventional setup of a macroscopic ferromagnet in a microwave cavity. Our scheme uses the ground state of an ellipsoid shaped magnet, which displays anisotropic quantum fluctuations akin to a squeezed vacuum. The magnetization collapses to a cat state by either a single-photon or a parity measurement of the microwave cavity state. We find that a cat state with two components separated by $\sim5\hbar$ is feasible and briefly discuss potential experimental setups that can achieve it.

 Description
 Adult males, SVL 48.4 mm; head longer than wide (HL/HW = 1.06); nostrils closer to the tip of the snout than to the eyes, loreal region almost concave; tympanum round, distinct, almost equal to eye diameter (TY/EY = 0.90, TY/SVL = 0.016); vomerine teeth present, short; there is a distinct dorsolateral fold. Disks of fingers and toes are small, clear; length of fingers (longest to shortest) 3> 1> 4> 2, third finger disk diameter (F3D) with ratio of F3D/SVL about 0.063; the formula for the web of the toe, I 1 / – 1 II 0 – 11 / III 0 – 2 IV 2 – 0 V, follows that used by Savage and 2 2 Heyer (1997); length of tibia, ratio of TL/SVL about 0.526; length of toe (longest to shortest) 4> 5> 3> 2> 1; subarticular tubercles developed; inner metatarsal is oval; outer metatarsal is very small. Dorsal surfaces are brown; there are dark lines on the limbs.
 Habitat
 Several males were observed among herbaceous plants in the lake margin, calling during the first survey in plots 7 and 8. The presence of this species is easily determined because males vocalise in large groups (Kurniati 2016). This species is often found actively jumping among plants in the lake margin. It was found active from 19 to 21°C and at 86 – 99% humidity.
 Remarks
 This species was observed in the lowlands (<700 – 800 m asl) in the central and northern parts of Sulawesi (Iskandar and Mumpuni 2004; Wanger et al. 2011). However, our results indicate that this species also occurs from 1650 to 1700 m asl in the open areas used for camping (plots 7 and 8), and in primary forest (plot 4). This species was also found on Buton Island and other surrounding islands (Gillespie et al. 2005), in the Nantu Gorontalo Wildlife Reserve and surrounding areas (Khairunnisa 2014) at 600 m elevation, and in Pohuwato Gorontalo Forest (Subasli 2015).

description: We review recent progress of understanding and resolving instabilities driven by mismatch between the Fermi surfaces of the pairing quarks in 2-flavor color superconductor. With the increase of mismatch, the 2SC phase exhibits chromomagnetic instability as well as color neutral baryon current instability. We describe the 2SC phase in the nonlinear realization framework, and show that each instability indicates the spontaneous generation of the corresponding pseudo Nambu-Golstone current. The Nambu-Goldstone currents generation state covers the gluon phase as well as the one-plane wave LOFF state. We further point out that, when charge neutrality condition is required, there exists a narrow unstable LOFF (Us-LOFF) window, where not only off-diagonal gluons but the diagonal 8-th gluon cannot avoid the magnetic instability. In this Us-LOFF window, the diagonal magnetic instability cannot be cured by off-diagonal gluon condensate in the color superconducting phase.

description: With the recent upsurge of Bdelloidea discoveries in permanently cold environments, members of the group represent prime candidates for better understanding adaptations to one of the most pervasive abiotic stressors; cold. Previous studies have highlighted the role of inducing cold stress tolerance through manipulation of the purine and energy metabolic pathways. Genomic alterations to these regions have been evaluated to offset the molecular and cellular dysfunctions associated with cold exposure (i.e. decreased molecular motion) by increasing intracellular adenylate pool levels. Here, through means of differential expression analysis, the recently discovered Icelandic glacial bdelloids (family Philodinidae) are compared against the current bdelloid reference; Adineta vaga. The intent is to identify any members of the purine and energy metabolic pathways exhibit changes in expression that may induce cold tolerance. The assessment of differentially expressed genes shared across all Icelandic bdelloid samples revealed two genes of interest suggested to play a role in cold tolerance; ADK1 and AT5G. Predicted to encode for adenylate kinase and ATP synthase lipid-binding protein [mitochondrial], respectively. As well, an overabundance of genes encoding ribosomal proteins and dynein heavy chain were discovered within the top differentially expressed genes with relative expression values shared across all Icelandic samples. Furthermore, gene enrichment analysis of the differentially expressed datasets provided insight into the prime components, processes, and functions impacted by changes in expression. Giving way to one of, if not the first, transcriptomic profiling of members from family Philodinidae.

description: The two-neutrino double beta decay matrix elements and half-lives of $^{48}$Ca, are calculated within a shell-model approach for transitions to the ground state and to the $2^+$ first excited state of $^{48}$Ti. We use the full $pf$ model space and the GXPF1A interaction, which was recently proposed to describe the spectroscopic properties of the nuclei in the nuclear mass region A=47-66. Our results are $T_{1/2}(0^{+}\to 0^{+})$ = $3.3\times 10^{19}$ $yr$ and $T_{1/2}(0^{+}\to 2^{+})$ = $8.5\times 10^{23}$ $yr$. The result for the decay to the $^{48}$Ti 0$^+$ ground state is in good agreement with experiment. The half-life for the decay to the 2$^+$ state is two orders of magnitude larger than obtained previously.

description: The ejecta velocity is a very important parameter in studying the structure and properties of Type Ia supernovae (SNe Ia). It is also a candidate key parameter in improving the utility of SNe Ia for cosmological distance determinations. Here we study the velocity distribution of a sample of 311 SNe Ia from the kaepora database. The velocities are derived from the Si II $λ$6355 absorption line in optical spectra measured at (or extrapolated to) the time of peak brightness. We statistically show that the observed velocity has a bimodal Gaussian distribution consisting of two groups of SNe Ia: Group I with a lower but narrower scatter ($μ_1 = 11000 \text{km s}^{-1}$, $σ_1 = 700 \text{km s}^{-1}$), and Group II with a higher but broader scatter ($μ_2 = 12300 \text{km s}^{-1}$, $σ_2 = 1800 \text{km s}^{-1}$). The population ratio of Group I to Group II is 201:110 (65%:35%). There is substantial degeneracy between the two groups, but for SNe Ia with velocity $v > 12000 \text{km s}^{-1}$, the distribution is dominated by Group II. The true origin of the two components is unknown, though there could be that naturally there exist two intrinsic velocity distributions as observed. However, we try to use asymmetric geometric models through statistical simulations to reproduce the observed distribution assuming all SNe Ia share the same intrinsic distribution. In the two cases we consider, 35\% of SNe Ia are considered to be asymmetric in Case 1, and all SNe Ia are asymmetric in Case 2. Simulations for both cases can reproduce the observed velocity distribution but require a significantly large portion ($>35\%$) of SNe Ia to be asymmetric. In addition, the Case 1 result is consistent with recent polarization observations that SNe Ia with higher Si II $λ$6355 velocity tend to be more polarized.
