description: Background: Concerns regarding the primary stability of early adjustable loop button (ALB) devices for cortical fixation of tendon grafts in anterior cruciate ligament reconstruction (ACLR) have led to the development of new implant designs. Purpose: To evaluate biomechanical stability of recent ALB implants in comparison with a continuous loop button (CLB) device. Study Design: Controlled laboratory study. Methods: ACLR was performed in a porcine model (n = 40) using 2-strand porcine flexor tendons with a diameter of 8 mm. Three ALB devices (Infinity Button [ALB1 group]; Tightrope II RT [ALB2 group]; A-TACK [ALB3 group]) and 1 CLB device (FlippTack with polyethylene suture) were used for cortical tendon graft fixation. Cyclic loading (1000 cycles up to 250 N) with complete unloading were applied to the free end of the tendon graft using a uniaxial testing machine, followed by load to failure. Elongation, stiffness, yield load, and ultimate failure load were recorded and compared between the groups using a Kruskal-Wallis test with post hoc Dunn correction. Results: Elongation after 1000 cycles at 250 N was similar between groups (ALB1, 4.5 ± 0.7 mm; ALB2, 4.8 ± 0.8 mm; ALB3, 4.5 ± 0.6 mm; CLB, 4.5 ± 0.8 mm), as was load to failure (ALB1, 838 ± 109 N; ALB2, 930 ± 89 N; ALB3, 809 ± 103 N; CLB, 842 ± 80 N). Stiffness was significantly higher in the ALB1 group compared with the CLB group (262.3 ± 21.6 vs 229.3 ± 15.1 N/mm; P < .05). No significant difference was found between the 4 groups regarding yield load. Constructs failed either by rupture of the loop, breakage of the button, or rupture of the tendon. Conclusion: The tested third-generation ALB devices for cortical fixation in ACLR withstood cyclic loading with complete unloading without significant differences to a CLB device.
Clinical Relevance: The third-generation ALB devices tested in the present study provided biomechanical stability comparable with that of a CLB device. Furthermore, ultimate failure loads of all tested implants exceeded the loads expected to occur in the postoperative period after ACLR.

description: We calculated numerically the localization length index $ν$ for the Chalker-Coddington model of the plateau-plateau transitions in the quantum Hall effect. By taking into account finite size effects we have obtained $ν= 2.593 \pm 0.0297$. The calculations were carried out by two different programs that produced close results, each one within the error bars of the other. We also checked the possibility of logarithmic corrections to finite size effects and found, that they come with much larger error bars for $ν$.

description: In this paper we investigate the connectedness and the isomorphism problems for zig-zag products of two graphs. A sufficient condition for the zig-zag product of two graphs to be connected is provided, reducing to the study of the connectedness property of a new graph which depends only on the second factor of the graph product. We show that, when the second factor is a cycle graph, the study of the isomorphism problem for the zig-zag product is equivalent to the study of the same problem for the associated pseudo-replacement graph. The latter is defined in a natural way, by a construction generalizing the classical replacement product, and its degree is smaller than the degree of the zig-zag product graph. Two particular classes of products are studied in detail: the zig-zag product of a complete graph with a cycle graph, and the zig-zag product of a $4$-regular graph with the cycle graph of length $4$. Furthermore, an example coming from the theory of Schreier graphs associated with the action of self-similar groups is also considered: the graph products are completely determined and their spectral analysis is developed.

description: Time perception is essential for task switching, and in the mammalian brain appears alongside other processes. Memristors are electronic components used as synapses and as models for neurons. The d.c. response of memristors can be considered as a type of short-term memory. Interactions of the memristor d.c. response within networks of memristors leads to the emergence of oscillatory dynamics and intermittent spike trains, which are similar to neural dynamics. Based on this data, the structure of a memristor network control for a robot as it undergoes task switching is discussed and it is suggested that these emergent network dynamics could improve the performance of role switching and learning in an artificial intelligence and perhaps create artificial time perception.

description: In this article, we focus on stochastic orders to compare the magnitudes of two parallel systems from Weibull distributions when one set of scale parameters majorizes the other. The new results obtained here extend some of those proved by Dykstra et al. (1997) and Joo and Mi (2010) from exponential to Weibull distributions. Also, we present some results for parallel systems from multiple-outlier Weibull models.

description: Background: Metacarpal shaft fractures are common and can be treated nonoperatively. Shortening, angulation, and rotational deformity are indications for surgical treatment. Various forms of treatment with advantages and disadvantages have been documented. The purpose of the study was to determine the stability of fracture fixation with intramedullary headless compression screws in two types of metacarpal shaft fractures and compare them to other common forms of rigid fixation: dorsal plating and lag screw fixation. It was hypothesized that headless compression screws would demonstrate a biomechanical stronger construct. Methods: Five matched paired hands (age 60.9 ± 4.6 years), utilizing non-thumb metacarpals, were used for comparative fixation in two fracture types created by an osteotomy. In transverse diaphyseal fractures, fixation by headless compression screws (n = 7) and plating (n = 8) were compared. In long oblique diaphyseal fractures, headless compression screws (n = 8) were compared with plating (n = 8) and lag screws (n = 7). Testing was performed using an MTS frame producing an apex dorsal, three point bending force. Peak load to failure and stiffness were calculated from the load-displacement curve generated. Results: For transverse fractures, headless compression screws had a significantly higher stiffness and peak load to failure, means 249.4 N/mm and 584.8 N, than plates, means 129.02 N/mm and 303.9 N (both p < 0.001). For long oblique fractures, stiffness and peak load to failure for headless compression screws were means 209 N/mm and 758.4 N, for plates 258.7 N/mm and 518.5 N, and for lag screws 172.18 N/mm and 234.11 N. There was significance in peak load to failure for headless compression screws vs plates (p = 0.023), headless compression screws vs lag screws (p < 0.001), and plates vs lag screws (p = 0.009). There was no significant difference in stiffness between groups. Conclusion: Intramedullary fixation of diaphyseal metacarpal fractures with a headless compression screw provides excellent biomechanical stability. Coupled with lower risks for adverse effects, headless compression screws may be a preferable option for those requiring rapid return to sport or work.

description: We analyze density-density correlations of expanding clouds of weakly interacting two-dimensional Bose gases below and above the Berezinskii-Kosterlitz-Thouless transition, with particular focus on short-time expansions. During time-of-flight expansion, phase fluctuations of the trapped system translate into density fluctuations, in addition to the density fluctuations that exist in in-situ. We calculate the correlations of these fluctuations both in real space and in momentum space, and derive analytic expressions in momentum space. Below the transition, the correlation functions show an oscillatory behavior, controlled by the scaling exponent of the quasi-condensed phase, due to constructive interference. We argue that this can be used to extract the scaling exponent of the quasi-condensate experimentally. Above the transition, the interference is rapidly suppressed when the atoms travel an average distance beyond the correlation length. This can be used to distinguish the two phases qualitatively.

description: The production and consumption of coffee generates large amounts of waste which, if released into the environment, could cause unacceptable pollution. The search for alternatives for the use of these waste materials, namely coffee silver skin (CSS) and spent coffee grounds (SCG), is of great importance from an environmental and economic point of view. In this context, the present study was conducted to evaluate the use of CSS and SCG as mineral sources in order to strengthen their status as novel foods, which is currently not recognised. With the aim of validating the content of metals and metalloids in CSS and SCG, a comparative study of green and roasted coffee was also conducted. The results of the HR-ICP-MS analyses showed that coffee and coffee by-products contain high levels of macro essential elements: K (2387–35 993 mg/kg), Mg (1263–5298 mg/kg) and Na (82.6–170 mg/kg). Among the essential trace elements, Fe predominated with amounts between 41.8 and 728 mg/kg. The essential elements in the ultra-trace range (Mo, Cr, Co and Se) are found in amounts between 0.02 and 2.42 mg/kg. The content of toxic elements (Pb, As, Cd and Sn) is in the range of 0.01–0.25 mg/kg, which is below the maximum levels set by the EU Commission for these elements in foodstuff. However, the levels of Rb, Ba, Sr, Ti and Al are high, and range from 2.33 to 764 mg/kg. Considering the high content of essential elements in CSSs that are useful for daily human needs, the potential use of CSS should be encouraged. On the other hand, in order to meet the requirements for the use of novel foods, monitoring of potentially toxic elements must be carried out.

description: Tea is a highly consumed beverage around the world, and many studies have indicated its health benefits. However, tea products may contain heavy metals that may cause negative health effects due to their toxicity. This study aimed to quantify the levels of copper (Cu), zinc (Zn), lead (Pb) and cadmium (Cd) in six different imported black tea brands marketed in Mashhad city, Iran. Twenty samples from each six black tea brands were obtained from the markets of Mashhad city, Iran, in 2012. Overall, the content of Cu, Zn, Pb and Cd ranged 6.81–35.21 mg/kg (mean = 15.87 mg/kg), 14.61–164.84 mg/kg (mean = 47.68 mg/kg), 0.038–1.62 mg/kg (mean = 0.72 mg/kg) and 0.006–0.19 (mean = 0.05 mg/kg), respectively. The mean concentration of Zn in brands C, E and F, the mean concentration of Pb in brand B and the mean concentration of Cd in brand E exceeded the Iranian and WHO standard levels. Additionally, the estimation of hazard index (HI) showed that there is no potential adverse health effect due to the consumption of the studied tea samples (HI < 1). In terms of HI, the brands were ordered as B > D > F > E > A > C. However, estimation of excess lifetime cancer risk (ELCR) for Pb showed that there is a significant lifetime cancer risk as a result of consuming the black tea products. but the estimation of ELCR for Cd showed no potential health risks.

description: In this research, tungsten oxide (WO3), silver oxide (Ag2O), and Ag2O/WO3 nanocomposites were synthesised by precipitation and sonication method, respectively. X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and UV-Visible spectroscopy were used to confirm the structural, spectral, morphological, and optical properties of as-synthesised samples, respectively. The as-prepared Ag2O/WO3 nanocomposite showed improved photocatalytic degradation activity for rhodamine B and methylene blue under solar light compared to pristine WO3 and Ag2O. The percentage degradation values were 79.6%, 86.1% and 90.8% for WO3, Ag2O and Ag2O/WO3 nanocomposite for methylene blue and 70.9%, 80.7% and 87.25% for rhodamine B. One of the possible reasons behind this improved photocatalytic degradation was decreased recombination of photo-generated holes and electrons due to the formation of nanocomposite between WO3 and Ag2O. Optical band gap values for WO3, Ag2O and Ag2O/WO3 nanocomposite were 2.93 eV, 1.59 eV and 1.38 eV, respectively. The Mott-Schottky plot confirmed the formation of nanocomposite and p-type and n-type behaviour of Ag2O and WO3, respectively.

description: Offloading is a popular way to overcome the resource and power constraints of networked embedded devices, which are increasingly found in industrial environments. It involves moving resource-intensive computational tasks to a more powerful device on the network, often in close proximity to enable wireless communication. However, many Industrial Internet of Things (IIoT) applications have real-time constraints. Offloading such tasks over a wireless network with latency uncertainties poses new challenges. In this paper, we aim to better understand these challenges by proposing a system architecture and scheduler for real-time task offloading in wireless IIoT environments. Based on a prototype, we then evaluate different system configurations and discuss their trade-offs and implications. Our design showed to prevent deadline misses under high load and network uncertainties and was able to outperform a reference scheduler in terms of successful task throughput. Under heavy task load, where the reference scheduler had a success rate of 5%, our design achieved a success rate of 60%.

description: Alloying Ti-Al-N coatings with Ta has proven to enhance their hardness, thermal stability, and oxidation resistance. However, especially for arc-evaporated Ti-Al-Ta-N coatings only limited information on the detailed influence of the elements on various properties is available. Therefore, we have developed arc-evaporated Ti1-x-yAlxTayN coatings with various Al (x = 0.50 - 0.65) and Ta (y = 0.00 - 0.15) contents. While the thermal stability of our coatings during annealing in inert He atmosphere increases with increasing Ta content, best results are obtained for specific Ta-Al ratios during oxidation. Single phase cubic Ti0.32Al0.60Ta0.08N yields a mass-gain of only ~5 % after 5 h at 950 °C in synthetic air, whereas Ti0.35Al0.65N is completely oxidized after 15 min. This is in part based on the suppressed anatase and direct rutile TiO2 formation at a defined Ta-Al content. Consequently, the anatase-to-rutile transformation, generally observed for Ti1-xAlxN, is absent. This reduces the generation of pores and cracks within the oxide scale and especially at the nitride-oxide interface, leading to the formation of a protective rutile and corundum based oxide scale. This is also reflected in the pronounced decrease in activation energy for the protective scale formation from 232 kJ/mol for Ti0.35Al0.65N down to 14.5 kJ/mol for Ti0.32Al0.60Ta0.08N. Based on our results we can conclude that especially phase transformations within the oxide scale need to be suppressed, as the connected volume changes lead to the formation of cracks and pores.

description: Flow and thermal effects concerned with liquid crystal growth are studied nonlinearly for low Prandtl numbers, in an axisymmetric steady configuration with endwalls present. Full solutions are obtained by finite element simulation to examine the influences of aspect ratio, Marangoni number and Rayleigh number. In particular a `lemonhead' phenomenon is found in which the velocity profiles acquire a very localised bell-shaped form as jet like flow starts to emerge, when the relative size of the Marangoni number increases above a finite critical value which is identified. Wide-domain and narrow-domain analyses are then presented, showing favourable agreement with the full solutions and explaining the impact of the end walls on the motion, especially through slender flow modelling in the narrow-domain context. Sensitive scalings for the relative effects of the Marangoni and Rayleigh numbers emerge, and the lemonhead phenomenon is also accounted for as a substantial change in the convective flow structure.

description: Theoretical models of accretion discs and observational data indicate that the X-ray emission from the inner parts of an accretion disc can irradiate its outer regions and induce a thermal wind, which carries away the mass and angular momentum from the disc. Our aim is to investigate the influence of the thermal wind on the outburst light curves of black hole X-ray binary systems. We carry out numerical simulations of a non-stationary disc accretion with wind using upgraded open code freddi. We assume that the wind launches only from the ionised part of the disc and may turn off if the latter shrinks fast enough. Our estimates of the viscosity parameter $α$ are shifted downward compared to a scenario without a wind. Generally, correction of $α$ depends on the spectral hardness of central X-rays and the disc outer radius, but unlikely to exceed a factor of 10 in the case of a black hole low-mass X-ray binary (BH LMXB). We fit 2002 outburst of BH LMXB 4U 1543-47 taking into account the thermal wind. The mass loss in the thermal wind is of order of the accretion rate on the central object at the peak of the outburst. New estimate of the viscosity parameter $α$ for the accretion disc in this system is about two times lower than the previous one. Additionally, we calculate evolution of the number of hydrogen atoms towards 4U 1543-47 due to the thermal wind from the hot disc.

description: Privacy Shielding against Mass Surveillance provides a step by step tactical approach to protecting the privacy of all the users of the internet from mass surveillance programs by the governments and other state agencies. Protection of privacy is of prime importance and Privacy Shielding provides the right means against mass surveillance programs and from malicious users trying to gain access to your systems. Although protection is difficult when massive government agencies like the National Security Agency and The Government Communications Headquarters target internet users for surveillance, it is possible because the target is not you as an individual but the entire mass as a whole. With the right approach and a broad perspective of the term Privacy, it is possible for one to freely access and share information over the internet without being victims of surveillance.

description: Antibiotics and antibacterials, including sulfonamides, are components of the veterinary armamentarium used to prevent and treat diseases in seafood. However, the accumulation of veterinary drug residues in seafood can cause food safety concerns. This study aimed to verify the quantitative analytical method for sulfonamides, trimethoprim, ormetoprim, and dapsone in seafood and to apply it to fish and shrimp distributed in Korean market. In the present study, three types of matrices (shrimp, flatfish, and eels) were used to detect drugs (n = 25) (sulfonamides (n = 21), trimethoprim, ormetoprim, dapsone, and monoacetyldapsone). Matrices were extracted with acetonitrile and mixed with 2 g of magnesium sulfate and 1 g of sodium acetate. After agitation, supernatants were mixed with 300 mg of C18 and centrifuged again. Then the supernatant was evaporated, dissolved in 50% methanol, and filtered through a PTFE filter. Extracts (5 µl) were then injected into the liquid chromatography-tandem mass spectrometry system. The method was validated in terms of limit of detection, limit of quantitation, decision limit, decision capability, matrix effects, intra/inter-day accuracies, precisions, and stabilities and the method was applied to fish and shrimp sold in the Korean market. The validation results were found to be satisfactory. As a result of applying the validated method to fish and shrimp samples purchased from the Korean market, sulfacetamide, sulfadimethoxine, sulfamethoxazole, and sulfanilamide were detected in shrimp samples. The devised method for analysing antibiotics in seafood samples enables antibiotic detection in fish samples distributed in the global market and should aid the adoption of preventative measures.

description: Focusing on the effects of system interaction on survivability during long-duration interstellar missions, this presentation introduces an agent-based model of the MELiSSA regenerative ecosystem. This model, created and implemented by the DSTART team at TU Delft, enables exploration of design options for a complex and evolvable starship with water, food and oxygen regeneration, and recycling of waste. The five MELiSSA compartment systems and their interactions have been modeled explicitly with operational agents representing humans, bioreactors and plant plots, and with corresponding mass flows of chemicals. The state of each agent, its component system, and the interaction between systems can be tracked in detail during each stage of the loop. Because of this, the impact of unpredictable events such as radiation on performance and population growth rate can be explored for a range of different scenarios. The design and implementation of the model provides additional advantages by making it easier for the researchers to visualize the whole process. The different levels of abstraction used to model the MELiSSA loop will be presented, together with the first, very promising results.

description: The survivability of a regenerative life support system during long-duration missions in interstellar space was simulated using an agent-based model (ABM) of MELiSSA. In this ABM, humans, plant plots and bioreactors are modeled as virtual agents that interact with each other. The ABM approach enables the introduction of heterogeneity at the level of agent attributes, and thus allows for the study of complex interactions that cannot be observed in more traditional equation-based modeling techniques. Properties, behavior, life cycle (e.g. growth curves and susceptibility to nourishment deficits), and rules of interaction are specifically modelled for each type of agent. The behaviors are modeled according to the major chemical reactions and productivities of each MELiSSA compartment, as documented in publicly available sources. A first series of simulation experiments investigates the survivability of the system under stress conditions of two types: stochastic metabolic efficiencies and environmental stressors. The following environmental stressors were conceptually simulated: cosmic radiation reducing metabolic functionality, and particle impact causing loss of life support system elements. A second series of simulation experiments explores the impact of different policies for nutrient distribution, both under normal and aforementioned stress conditions. The research on which this paper reports is part of the E|A|S (Evolving Asteroid Starships) project by the DSTART team at Delft University of Technology. The project entails conceptual research on interstellar travel, including onboard regenerative ecosystems.

description: We propose 10 highly-charged ions as candidates for the development of next generation atomic clocks, quantum information, and search for $α$-variation. They have long-lived metastable states with transition frequencies to the ground state between 170-3000 nm, relatively simple electronic structure, stable isotopes and high sensitivity to $α$-variation (e.g., Sm$^{14+}$, Pr$^{10+}$, Sm$^{13+}$, Nd$^{10+}$). We predict their properties crucial for the experimental exploration and highlight particularly attractive systems for these applications.

description: Dust aerosol plays a fundamental role in the behavior and evolution of the Martian atmosphere. The first five Mars years of Mars Exploration Rover data provide an unprecedented record of the dust load at two sites. This record is useful for characterization of the atmosphere at the sites and as ground truth for orbital observations. Atmospheric extinction optical depths have been derived from solar images after calibration and correction for time-varying dust that has accumulated on the camera windows. The record includes local, regional, and globally extensive dust storms. Comparison with contemporaneous thermal infrared data suggests significant variation in the size of the dust aerosols, with a 1 μm effective radius during northern summer and a 2 μm effective radius at the onset of a dust lifting event. The solar longitude (LS) 20-136° period is also characterized by the presence of cirriform clouds at the Opportunity site, especially near LS=50 and 115°. In addition to water ice clouds, a water ice haze may also be present, and carbon dioxide clouds may be present early in the season. Variations in dust opacity are important to the energy balance of each site, and work with seasonal variations in insolation to control dust devil frequency at the Spirit site.

description: This systematic review aimed to analyze the determinant factors of household food waste in Southeast Asia. Two databases (Web of Science and ScienceDirect) and hand searching were used to select the articles. A total of 12 studies were identified in this review. Household food waste behavior was associated with psychological factors, food quality and safety, and consumer behavior (planning, purchasing, storing, and eating behaviors). This systematic review implies that understanding our needs, families, and eating habits are essential for reducing food waste.

description: In this Reply we include the corrections suggested in the Comment [Phys. Rev. Lett. 131, 169001]. We show that their impact on our results is small, and that the overall conclusion of the Article [Phys. Rev. Lett. 129, 111102] are robust. As pointed out in the Article, it is crucial to account for the statistical uncertainty in the ringdown starting time, neglected in most previous studies. This uncertainty is ~40 times larger than the systematic shift induced by the software bug mentioned in the Comment. The remaining discrepancies between the Comment and the Article can be attributed to additional differences in the setup, notably the sampling rate and the noise estimation method (in the Article the latter was chosen to mimic the original methods of [Phys. Rev. Lett. 123, 111102]). Beyond data analysis considerations, the physics of the problem cannot be ignored. As shown in [arXiv:2302.03050], a model consisting of a sum of constant-amplitude overtones starting at the peak of the waveform introduces uncontrolled systematic uncertainties in the measurement due to dynamical and strong-field effects. These theoretical considerations imply that studies based on such models cannot be interpreted as black hole spectroscopy tests.

description: Geographical information systems are ideal candidates for the application of parallel programming techniques, mainly because they usually handle large data sets. To help us deal with complex calculations over such data sets, we investigated the performance constraints of a classic master-worker parallel paradigm over a message-passing communication model. To this end, we present a new approach that employs an external database in order to improve the calculation/communication overlap, thus reducing the idle times for the worker processes. The presented approach is implemented as part of a parallel radio-coverage prediction tool for the GRASS environment. The prediction calculation employs digital elevation models and land-usage data in order to analyze the radio coverage of a geographical area. We provide an extended analysis of the experimental results, which are based on real data from an LTE network currently deployed in Slovenia. Based on the results of the experiments, which were performed on a computer cluster, the new approach exhibits better scalability than the traditional master-worker approach. We successfully tackled real-world data sets, while greatly reducing the processing time and saturating the hardware utilization.

description: We present a new determination of the concentration-mass relation for galaxy clusters based on our comprehensive lensing analysis of 19 X-ray selected galaxy clusters from the Cluster Lensing and Supernova Survey with Hubble (CLASH). Our sample spans a redshift range between 0.19 and 0.89. We combine weak lensing constraints from the Hubble Space Telescope (HST) and from ground-based wide field data with strong lensing constraints from HST. The result are reconstructions of the surface-mass density for all CLASH clusters on multi-scale grids. Our derivation of NFW parameters yields virial masses between 0.53 x 10^15 and 1.76 x 10^15 M_sol/h and the halo concentrations are distributed around c_200c ~ 3.7 with a 1-sigma significant negative trend with cluster mass. We find an excellent 4% agreement between our measured concentrations and the expectation from numerical simulations after accounting for the CLASH selection function based on X-ray morphology. The simulations are analyzed in 2D to account for possible biases in the lensing reconstructions due to projection effects. The theoretical concentration-mass (c-M) relation from our X-ray selected set of simulated clusters and the c-M relation derived directly from the CLASH data agree at the 90% confidence level.

description: Refugees experience elevated risk of chronic disease post-resettlement. Understanding contributors to refugee knowledge of the connection between food and health may help promote healthful resettlement. A random survey was conducted with Cambodian refugee and asylee women in Lowell, MA (n = 160). Knowledge of the connection between health and food categories (meat with fat, soda, fast food, high-sodium sauces, salt, vegetables, fruit, and whole grains) was assessed. High food security, literacy, and having participated in nutrition education were related to higher knowledge. Approaches to refugee health should include improving food security and should be tailored to varied literacy levels.

description: Chemical computation model was inspired by chemical reactions: procedures react with data as molecules of compounded solutions react to each other. This model has a concurrent and non-deterministic way of computing, that
 results transparent parallelism instead of artificially sequential algorithms.There has been some theoretical examination of this model, but there are not many practical usage. In this paper chemical approach is used to solve a well-known logical game, Sudoku. The basics of Higher-Order Chemical Language and the chemical computation model is explained through the case-study of solving sudoku puzzle.

description: In this paper hierarchical analysis-suitable T-splines (HASTS) are developed. The resulting spaces are a superset of both analysis-suitable T-splines and hierarchical B-splines. The additional flexibility provided by the hierarchy of T-spline spaces results in simple, highly localized refinement algorithms which can be utilized in a design or analysis context. A detailed theoretical formulation is presented including a proof of local linear independence for analysis-suitable T-splines, a requisite theoretical ingredient for HASTS. Bézier extraction is extended to HASTS simplifying the implementation of HASTS in existing finite element codes. The behavior of a simple HASTS refinement algorithm is compared to the local refinement algorithm for analysis-suitable T-splines demonstrating the superior efficiency and locality of the HASTS algorithm. Finally, HASTS are utilized as a basis for adaptive isogeometric analysis.
