description: La Libreria Patria è – tra i fondi della Biblioteca cantonale di Lugano – quello che, senza il timore di incorrere in eccessi, si può definire come il suo fiore all’occhiello. Dal carattere prettamente regionale – legato alla storia, alla cultura e al territorio del Canton Ticino –, essa costituisce un unicum non solo per le sue peculiarità intrinseche, ma anche per il carattere straordinario già sin dalla sua costituzione. Patrimonio ricchissimo – in termini sia quantitativi che di varietà delle risorse – la Libreria Patria è un mondo che vale la pena di essere scoperto e portato a conoscenza dei più giovani. Il presente lavoro si propone dunque di promuovere il Fondo attraverso una breve attività di animazione rivolta in particolare agli studenti di Scuola media del secondo ciclo di orientamento.

description: Experimental functional analysis (FA) is often used in clinical settings to identify maintaining variables of behavior but may not be used as part of functional behavior assessments (FBA) in public schools. Barriers such as time, staff training, and effective current practice have limited the use of FA in public school FBA. Recent literature has shown that effective variations of FA can be used to overcome setting-specific barriers in public schools. The purpose of the current study will be to evaluate the current methodologies of FA for correlation of results as well as across measures of efficiency. This evaluation may determine whether a specific method of FA will be most effective in applied settings, as well as to determine if FA methods may garner different results across a single participant. The possible implications of a socially valid and efficient means of FA for applied settings could provide school-based staff members a vital tool in determining the maintaining variables of problem behavior in public school settings, where time may be limited and staff may not have formal training in behavior analysis.
Reframing reform : positioning the Chinese economy in the World Bank
Creators: name: Meulbroek, Christopher
Publisher: name: University of British Columbia
Year: 2020

description: The rise of China as an economic power is one of the defining economic trends of last forty years. There has been considerable academic and policy controversy over the extent to which China’s political economy can be classified as capitalist, resulting, in many instances, in a problematic apriori distinction and separation between state and market. This thesis explores how development economists have managed this distinction through an extended case study of the World Bank. Through a critical discourse analysis of the Bank’s corpus of reports on China, along with a historical analysis of archival material, speeches, and academic journals, this thesis traces the Bank’s policy diagnoses, prognostications, and prescriptions since the late 1970s. Chapter 1 introduces the thesis by situating the role of the World Bank in the international development sector in general, and in China, in particular. Chapter 2 examines the first decade of the World Bank-China relationship. I argue that the Bank deployed the discursive technology of ‘transition’ to reduce the complexities of managing economic policy formulation within a state-socialist framework. Through an examination of industrial, labor, and financial policy discourses, I claim this ‘transition imaginary’ was predicated upon an ascendant hegemony of a neoliberal policy nexus within the Bank, coupled with the use of market-based policy instruments in Chinese economic statecraft. In the 1990s, however, the posited teleology from ‘central planning’ to ‘market economy’ grew unsustainable in the face of post-Soviet collapse and the continuation of state-backed credit provisioning to state-owned enterprises, weakening the dominance of the transition imaginary. Chapter 3 examines the introduction of the ‘gradualist model’ of economic reform in the World Bank in the uncertain geopolitical-economic context of the late 1980s. I argue the contested acceptance of ‘gradualism’ as a distinctive reform model challenged the Bank’s extant ‘shock therapy’ model, but was subsequently articulated into a unified post-Washington Consensus paradigm. Chapter 4 concludes by highlighting the significance of shifting discursive and institutional boundaries between market and plan in the global political economy.
Method development and proteomics applications of nonaqueous capillary electrophoresis – mass spectrometry
Creators: name: Cheng, Jianhui
Publisher: name: University of British Columbia
Year: 2021

description: Capillary electrophoresis (CE) is known for its low sample consumption, high-resolution efficiency as a separation technique, while mass spectrometry (MS) provides unprecedented selectivity and sensitivity as a detector, while adding another dimension in separation. The development of a robust CE-MS interface makes it possible to combine these two technologies for the analysis of many types of compounds. However, the coupling of CE to MS reduces its usable electrolyte ingredients substantially, and many of the popular buffer systems based on phosphate or borate, the MEKC methods dependent on the use of non-volatile surfactants, have to be excluded. As a result, formic acid and acetate buffers are the most widely used background electrolytes (BGEs) in CE-MS. In this work, we used mainly organic solvent systems to expand the choices of BGEs for CE-MS. In chapters 2 and 3, we presented two quantitative 100 % nonaqueous CE-MS methods for the separation and determination of small hydrophobic molecules. Two different BGEs were developed in this part: a basic buffer system for the analysis of negatively charged compounds and an acidic buffer system for the analysis of positively charged compounds. The compounds studied are three anthraquinones extracted from traditional Chinese medicine (TCM), Rhubarb, and six synthesized hydrophobic peptides, respectively. A high-organic-content CE-MS (HOCE) method was developed for the proteomics analysis of envelope proteins. A field amplified sample stacking technique was optimized to improve the concentration sensitivity of CE-MS for samples containing a large number of different analytes. The introduction of methanol into the buffer increased the performance of CE-MS for the detection of hydrophobic peptides in complex proteins digest. A half organic CE-MS method was used for the sequencing of novel mAbs. It was demonstrated that CE-MS/MS provided highly complementary information to LC-MS/MS with much less sample consumption. The last part of this thesis describes the application of a new generation mass spectrometry, timsTOF Pro connected with LC for the site-specific O-glycomics. In TIMS, charged compounds were separated based on their differential sizes and charges, similar to CE. The results suggest that combining CE-MS for PTMs analysis can be even more productive in the future.

description: In this paper we consider the plane curvilinear rod for which it is necessary to determine the elastic modulus i.e. the component of stiffness tensor B - B32. Three methods for determining B32 are suggested each of which is based on connection between translations and rotations in the rod theory and translations in the three-dimensional theory. During calculations of the required modulus, the components of displacements and rotations determined in several cross-sections are used. The result of the work is determination of the most suitable method of calculation of the required modulus.

description: We prove that for simple complex finite dimensional Lie algebras, affine Kac-Moody Lie algebras, the Virasoro algebra and the Heisenberg-Virasoro algebra, simple highest weight modules are characterized by the property that all positive root elements act on these modules locally nilpotently. We also show that this is not the case for higher rank Virasoro and for Heisenberg algebras.
A majorization-minimization approach to variable selection using spike and slab priors

description: We develop a method to carry out MAP estimation for a class of Bayesian regression models in which coefficients are assigned with Gaussian-based spike and slab priors. The objective function in the corresponding optimization problem has a Lagrangian form in that regression coefficients are regularized by a mixture of squared $l_2$ and $l_0$ norms. A tight approximation to the $l_0$ norm using majorization-minimization techniques is derived, and a coordinate descent algorithm in conjunction with a soft-thresholding scheme is used in searching for the optimizer of the approximate objective. Simulation studies show that the proposed method can lead to more accurate variable selection than other benchmark methods. Theoretical results show that under regular conditions, sign consistency can be established, even when the Irrepresentable Condition is violated. Results on posterior model consistency and estimation consistency, and an extension to parameter estimation in the generalized linear models are provided.

description: The Hofstadter butterfly spectral patterns of lattice electrons in an external magnetic field yield some of the most beguiling images in physics. Here we explore the magneto-electronic spectra of systems with moire spatial patterns, concentrating on the case of twisted bilayer graphene. Because long-period spatial patterns are accurately formed at small twist angles, fractal butterfly spectra and associated magneto-transport and magneto-mechanical anomalies emerge at accessible magnetic field strengths.
Visual grounding through iterative refinement
Creators: name: Fan, Zicong
Publisher: name: University of British Columbia
Year: 2020

description: The problem of visual grounding has attracted much attention in recent years due to its pivotal role in more general visio-lingual high level reasoning tasks (e.g., image captioning, VQA). Despite the tremendous progress in this area, the performance of most approaches has been hindered by the precision of bounding box proposals obtained in the early stages of the recent pipelines. To address this limitation, we propose a general progressive query-guided bounding box refinement architecture (OptiBox) that regresses the output of a visual grounding system closer to the ground truth. We apply this architecture in the context of the GroundeR model and the One-Stage Grounding model. The results from the GroundeR model show that our model can provide an additional grounding accuracy gain for a two-stage grounding system. Further, our experiments show that the proposed model can significantly improve bounding box precision when the predicted box of a grounding system deviates from the ground truth.

description: We investigate flow dynamics in rivers characterized by basin areas and daily mean discharge spanning different orders of magnitude. We show that the delayed increments evaluated at time scales ranging from days to months can be opportunely rescaled to the same non-Gaussian probability density function. Such a scaling breaks up above a certain critical horizon, where a behavior typical of thermodynamic systems at the critical point emerges. We finally show that both the scaling behavior and the break up of the scaling are universal features of river flow dynamics.

description: In this paper we define and study what we call the double Catalan monoid. This monoid is the image of a natural map from the 0-Hecke monoid to the monoid of binary relations. We show that the double Catalan monoid provides an algebraization of the (combinatorial) set of 4321-avoiding permutations and relate its combinatorics to various off-shoots of both the combinatorics of Catalan numbers and the combinatorics of permutations. In particular, we give an algebraic interpretation of the first derivative of the Kreweras involution on Dyck paths, of 4321-avoiding involutions and of recent results of Barnabei {\em et al.} on admissible pairs of Dyck paths. We compute a presentation and determine the minimal dimension of an effective representation for the double Catalan monoid. We also determine the minimal dimension of an effective representation for the 0-Hecke monoid.

Investigating mouse motor activity and learning behavior using quantitative trait locus (QTL) analysis to elucidate the genetic underpinnings of developmental coordination disorder (DCD)
Creators: name: Soundara Rajan, Jeffy Rajan
Publisher: name: University of British Columbia
Year: 2024

description: Developmental coordination disorder is a neuromotor disability of unknown etiology that affects 5–6% of school-aged children. A major hallmark of DCD is difficulty in motor learning, as children with DCD struggle with learning new skills, planning of movement, adapting to change, and automatizing motor patterns. Evidence suggests DCD is highly heritable and phenotypically heterogeneous; however, little is known about the genetic basis of DCD. Hence, this study aims to investigate motor behaviors that reflect the core symptoms of human DCD in BXD recombinant inbred strains of mice and correlate phenotypic traits to the known genotypes of the lines of BXD mice using sophisticated bioinformatic tools in the hopes of finding underlying genetics of the disorder. A total of 12 different BXD inbred lines and the two parental strains (B6 and DBA) were phenotypically examined. We conducted three phases of phenotyping: a neurodevelopmental battery post-natal day (P1-P15), general motor testing (P60-P81), and a motor learning battery (P90-P120), designed to focus on similarities to the symptomology of the human condition of DCD. To date, we have found nine statistically significant QTLs and several suggestive QTLs associated with our measures of general and skilled motor function, which are defined at a particular chromosomal locus within a 1.5 LOD support interval of the QTL. Of 304 genes, we identified 14 candidate genes based on expression, function and polymorphisms within the mapped QTL intervals. Of these 14 candidates, four genes (Cp1x1, Idua, Nrip1, Ltn1) were classified as priority genes that met all our criteria and were believed to have the highest impact on phenotype. To date, no connections have been found between these candidate genes and DCD-related pathogenesis. However, we have identified overlapping loci with previously reported phenotypic data within our mapped QTL interval of motor phenotypes. The findings of this study provide novel insights into genes that may influence DCD-like motor behavior. In the long term, uncovered genes with associated variation in motor phenotypes could provide insights into genetic factors underlying DCD in the human population and help provide opportunities for early and tailored intervention in children at risk for developmental difficulties.

description: We study the cluster algebras arising from cluster tubes with rank bigger than $1$. Cluster tubes are $2-$Calabi-Yau triangulated categories which contain no cluster tilting objects, but maximal rigid objects. Fix a certain maximal rigid object $T$ in the cluster tube $\mathcal{C}_n$ of rank $n$. For any indecomposable rigid object $M$ in $\mathcal{C}_n$, we define an analogous $X_M$ of Caldero-Chapton's formula (or Palu's cluster character formula) by using the geometric information of $M$. We show that $X_M, X_{M'}$ satisfy the mutation formula when $M,M'$ form an exchange pair, and that $X_{?}: M\mapsto X_M$ gives a bijection from the set of indecomposable rigid objects in $\mathcal{C}_n$ to the set of cluster variables of cluster algebra of type $C_{n-1}$, which induces a bijection between the set of basic maximal rigid objects in $\mathcal{C}_n$ and the set of clusters. This strengths a surprising result proved recently by Buan-Marsh-Vatne that the combinatorics of maximal rigid objects in the cluster tube $\mathcal{C}_n$ encode the combinatorics of the cluster algebra of type $B_{n-1}$ since the combinatorics of cluster algebras of type $B_{n-1}$ or of type $C_{n-1}$ are the same by a result of Fomin and Zelevinsky. As a consequence, we give a categorification of cluster algebras of type $C$.

description: Silicon (Si) accumulation is known to alleviate various biotic and abiotic stressors in plants with potential ecological consequences. However, for dicotyledonous plants our understanding of Si variation remains limited. We conducted a comparative experimental study to investigate (1) interspecific variation of foliar Si concentrations across 37 dicotyledonous forbs of temperate grasslands, (2) intraspecific variation in foliar Si concentration in response to soil Si availability, the influence of (3) phylogenetic relatedness, and (4) habitat association to moisture. Foliar Si differed markedly (approx. 70-fold) across the investigated forbs, with some species exhibiting Si accumulation similar to grasses. Foliar Si increased with soil Si availability, but the response varied across species: species with higher Si accumulation capacity showed a stronger response, indicating that they did not actively upregulate Si uptake under low soil Si availability. Foliar Si showed a pronounced phylogenetic signal, i.e., closely related species exhibited more similar foliar Si concentrations than distantly related species. Significant differences in foliar Si concentration within closely related species pairs nevertheless support that active Si uptake and associated high Si concentrations has evolved multiple times in forbs. Foliar Si was not higher in species associated with drier habitats, implying that in dicotyledonous forbs of temperate grasslands high foliar Si is not an adaptive trait to withstand drought. Our results demonstrated considerable inter- and intraspecific variation in foliar Si concentration in temperate forbs. This variation should have pervasive, but so far understudied, ecological consequences for community composition and functioning of temperate grasslands under land-use and climate change.

The root dynamics of the $σ$-flow in the NV equation is studied using the GH polynomials and then the Lax pair is found. In particulr, when $N=3,4,5$, one can get the Gold-fish model. The smooth rational solutions of the NV equation are also constructed via the extended Moutard transformation and the GH polynomials. The asymptotic behavior is discussed and then the smooth rational solution of the Liouville equation is obtained.

description: We analyze static point-to-set correlations in glass-forming liquids. The generic idea is to freeze the position of a set of particles in an equilibrium configuration and to perform sampling in the presence of this additional constraint. Qualitatively different geometries for the confining set of particles are considered and a detailed comparison of resulting static and dynamic correlation functions is performed. Our results reveal the existence of static spatial correlations not detected by conventional two-body correlators, which appear to be decoupled from, and shorter-ranged than, dynamical length scales characterizing dynamic heterogeneity. We find that the dynamics slows down dramatically under confinement, which suggests new ways to investigate the glass transition. Our results indicate that the geometry in which particles are randomly pinned is the best candidate to study static correlations.

From the study, it is recommended that effective strategies of preserving cassava products especially akpu should be developed in other to increase the demand and supply of the product.
Soft-Decoding-Based Strategies for Relay and Interference Channels: Analysis and Achievable Rates Using LDPC Codes

description: We provide a rigorous mathematical analysis of two communication strategies: soft decode-and-forward (soft-DF) for relay channels, and soft partial interference-cancelation (soft-IC) for interference channels. Both strategies involve soft estimation, which assists the decoding process. We consider LDPC codes, not because of their practical benefits, but because of their analytic tractability, which enables an asymptotic analysis similar to random coding methods of information theory. Unlike some works on the closely-related demodulate-and-forward, we assume non-memoryless, code-structure-aware estimation. With soft-DF, we develop {\it simultaneous density evolution} to bound the decoding error probability at the destination. This result applies to erasure relay channels. In one variant of soft-DF, the relay applies Wyner-Ziv coding to enhance its communication with the destination, borrowing from compress-and-forward. To analyze soft-IC, we adapt existing techniques for iterative multiuser detection, and focus on binary-input additive white Gaussian noise (BIAWGN) interference channels. We prove that optimal point-to-point codes are unsuitable for soft-IC, as well as for all strategies that apply partial decoding to improve upon single-user detection (SUD) and multiuser detection (MUD), including Han-Kobayashi (HK).

Regularization of fluctuations near the sonic horizon due to the quantum potential and its influence on the Hawking radiation

description: We consider dynamics of fluctuations in transonically accelerating Bose-Einstein condensates and luminous liquids (coherent light propagating in a Kerr nonlinear medium) using the hydrodynamic approach. It is known that neglecting the quantum potential (QP) leads to a singular behavior of quantum and classical fluctuations in the vicinity of the Mach (sonic) horizon, which in turn gives rise to the Hawking radiation. The neglect of QP is well founded at not too small distances $|x| \gg l_h$ from the horizon, where $l_h$ is the healing length. Taking the QP into account we show that a second characteristic length $l_r > l_h$ exists, such that the linear fluctuation modes become regularized for $|x| \ll l_r$. At $|x| \gg l_r$ the modes keep their singular behavior, which however is influenced by the QP. As a result we find a deviation of the high frequency tail of the spectrum of Hawking radiation from Planck's black body radiation distribution. Similar results hold for the wave propagation in Kerr nonlinear media where the length $l_h$ and $l_r$ exist due to the nonlinearity.

description: We describe a strategy to improve the efficiency of free energy estimates by reducing dissipation in nonequilibrium Monte Carlo simulations. This strategy generalizes the targeted free energy perturbation approach [Phys. Rev. E. 65, 046122, 2002] to nonequilibrium switching simulations, and involves generating artificial, "escorted" trajectories by coupling the evolution of the system to updates in external work parameter. Our central results are: (1) a generalized fluctuation theorem for the escorted trajectories, and (2) estimators for the free energy difference Delta F in terms of these trajectories. We illustrate the method and its effectiveness on model systems.

description: We study finite-temperature magnetization transport in a one-dimensional anisotropic Heisenberg model, focusing in particular on the gapped phase. Using numerical simulations by two different methods, a propagation of localized wavepackets and a study of nonequilibrium steady states of a master equation in a linear-response regime, we conclude that the transport at finite temperatures is diffusive. With decreasing temperature the diffusion constant increases, possibly exponentially fast. This means that at low temperatures the transition from ballistic to asymptotic diffusive behavior happens at very long times. We also study dynamics of initial domain wall like states, showing that on the attainable time scales they remain localized.

description: We study the effects of CP violation in charged Higgs boson production $pp\to t H^\pm + X$ at the LHC, as well as in the charged Higgs boson decays $H^\pm \to t b$ and $H^\pm \to W^\pm H_i^0$, $i=1,2,3$. The study is done in the framework of the type II complex Two Higgs Doublet Model (2HDM) with softly broken $Z_2$ symmetry. In this model violation of CP invariance is induced by the complex parameter $m^2_{12}$ of the tree-level Higgs potential. We calculate the CP violating rate asymmetries for $H^+$ and $H^-$ production and decays as well as for the combined processes at one-loop level and perform a detailed numerical analysis. All calculations are done with the automatic amplitude generator FeynArts and the calculational tool FormCalc, for which we have written a complete complex 2HDM model file and relevant fortran drivers. The implementation of the complex 2HDM in FeynArts and FormCalc is described. In comparison with the analogous results in the MSSM, all considered CP violating asymmetries are smaller by an order of magnitude and do not exceed 2 to 3%.

description: “Come progettare dei test per i ragazzi della SM che valutino le competenze comunicative degli allievi in L2?” Per rispondere a questo primo interrogativo di ricerca, sono state analizzati i test comunicativi all’interno di un quadro teorico, che comprende: storia dei test linguistici, analisi delle caratteristiche dei test comunicativi (separazione delle 4 competenze, validità, affidabilità, autenticità, livello di difficoltà), effetto dei test sull’insegnamento/apprendimento. Le conclusioni della ricerca dicono che i test comunicativi si progettano grazie al supporto degli obiettivi di comunicazione dei metodi in uso e grazie ai descrittori del “Quadro comune europeo di riferimento per le lingue” o di “LinguaLevel”, tenendo sempre conto delle qualità che questi tipi di test devono avere. Il secondo interrogativo di ricerca è il seguente: “I risultati dei test di tipo “comunicativo” sono diversi dai risultati dei test “tradizionali” per i singoli allievi?” Per rispondere a questa seconda domanda sono stati somministrati agli allievi della 3°BC di Morbio Inferiore due tipi di test per ogni unità del metodo in uso: uno comunicativo ed uno tradizionale. Cinque allievi su venticinque hanno ottenuto risultati diversi in modo significativo nei test: tre vanno meglio nei test tradizionali, due nei test comunicativi. Si evidenziando dunque diverse tipologie di apprendenti nella classe. Relatore: Gé Stoks. Materia: francese
Properties of the HII region populations of M51 and NGC 4449 from Halpha images with ACS on HST

description: We have used the images from the ACS on HST in Halpha, and in the neighboring continuum, to produce flux calibrated images of the large spiral galaxy M51, and the dwarf irregular NGC 4449. From these images we have derived the absolute luminosities in Halpha, the areas, and the positions with respect to the galactic centers as reference points, of over 2600 HII regions in M51 and over 270 HII regions in NGC 4449. Using this database we have derived luminosity (L)--volume (V) relations for the regions in the two galaxies, showing that within the error limits these obey the equation L ~ V^(2/3), which differs from the linear relation expected for regions of constant uniform electron density. We discuss briefly possible models which would give rise to this behavior, notably models with strong density inhomogeneities within the regions. Plotting the luminosity functions for the two galaxies we find a break in the slope for M51 at log(L) = 38.5 dex (units in erg s^(-1)) for M51 in good agreement with the previous ground-based study by Rand, and above this luminosity NGC 4449 also shows a sharp decline in its luminosity function, although the number of regions is too small to plot the function well at higher luminosities. The cumulative diameter distribution for the HII regions of M51 shows dual behaviour, with a break at a radius close to 100 pc, the radius of regions with the break luminosity. Here too we indicate the possible physical implications.

Progressive collapse induced by fire and blast
Creators: name: Forni, Daniele
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)

description: Comprehensive finite element modelling of key elements is essential to improve the robustness assessment of structures subjected to a coupled effect of fire and blast. Focusing the attention on steel structures, a method for a realistic multi-hazard approach is presented. The problem has been investigated at the material level first and then at the structural level. The material level was studied performing a detailed experimental investigation in a wide range of strain rates and temperatures. A typical structural steel, namely S355, has been studied. A Split Hopkinson Tensile Bar equipped with a water-cooled induction heating system was used for the mechanical characterisation at high strain rates (300 s−1, 500 s−1 and 850 s−1) and in a wide range of temperatures (20°C, 200°C, 400°C, 550°C, 700°C and 900°C). A Hydro-Pneumatic machine and a universal electromechanical testing machine were used for intermediate (5 s−1 and 25 s−1) and quasi-static (10−3 s−1) strain rate tests at room temperature, respectively. Results showed that the S355 structural steel is strain rate sensitive, keeping its strain hardening capacity with increasing strain rates. The temperature effect was studied by means of the reduction factors for the main mechanical properties. Results at high strain rates highlighted also the blue brittleness phenomenon between 400°C and 550°C. The link between the material and the structural level is a material constitutive law able to take into account the strain rate sensitivity and the thermal softening. The widely used constitutive law proposed by Johnson and Cook was calibrated using the experimental results. A critical review of this material model highlighted a perceptible variation of the thermal softening parameter at different temperatures. Following a fitting approach, a modification of the dimensionless temperature (T*) has been proposed. The structural level was numerically investigated adopting the calibrated material model. Explicit non-linear dynamic analyses of a steel column under fire conditions and followed by an explosion were performed. The commercial code LS-DYNA was used. A method for a realistic multi-hazard approach has been proposed by studying the residual load bearing capacity. The results can be also of great interest to establish the initial conditions that could potentially lead to the onset of progressive collapse in steel framed structures under a combined effect of fire and blast. As expected, the results indicated that the load bearing capacity is influenced by the stand-off distance, the charge size as well as the column boundary conditions. The time of fire loading at which an explosion is triggered is a critical parameter as well.

description: Cinnamaldehyde (CA) is one of the major active pharmaceutical ingredient of cinnamon bark. Hydrodistillation (HD) is usually used in CA extraction, however, the extraction yield is lower. The cell wall is a key factor limiting the extraction of essential oils. In-situ reactive heat breaking cell wall (RHB) could destroy the cell wall, which was conducive to the diffusion of CA. The aim of this work was to examine the effect of RHB pretreatment to HD extraction. Response surface methodology (RSM) was used to optimize RHB pretreatment parameters, and Box-Behnken Design (BBD) method was performed to evaluate the effects of different operating parameters. The maximum yield was increased to 3.31 ± 0.11% (w/w) from 2.08 ± 0.042% (w/w) after RSM optimization. Scanning electron microscopic (SEM) analysis showed that RHB destroyed and disrupted the cell wall of cinnamon bark. The GC analysis demonstrated that the purity of cinnamaldehyde was improved and no new components were presented in the extraction product from the cinnamon via RHB pretreatment. In conclusion, RHB is an effective pretreatment method for the CA extraction, and also may be used in the other herbal medicine extraction.
