1,3-N,O-Chelated complexes of rhodium and iridium : harnessing metal-ligand cooperativity for bond activation processes
Creators: name: Drover, Marcus Walter
Publisher: name: University of British Columbia
Year: 2017

description: This thesis explores the use of 1,3-N,O chelating ligands, amidates and phosphoramidates as ligands for rhodium and iridium in the +1 and +3 oxidation states. Toward this end, a series of novel group 9 complexes were prepared, characterized, and employed for cooperative small molecule activation and element-hydrogen (E-H) bond cleavage reactions. In Chapter 1, amides and phosphoramides are introduced as ligands for late transition metals. In particular, it is highlighted that such ligands have traditionally been used to form early transition metal and lanthanide N,O-chelated complexes, with the late transition metal chemistry being highly underdeveloped. In Chapter 2, the fundamental reactivity of rhodium(I) complexes having amidate ancillary ligands is presented including catalytic oxygen atom transfer using O₂ – the products of such reactions: η²-O₂ complexes were characterized using NMR spectroscopy and density functional theory (DFT). Chapter 3 details the use of 1,3-N,O chelated complexes of monovalent Rh(I) and Ir(I) for the controlled capture of HBCy₂, providing six-membered genuine metallaheterocycles bearing a δ-B-H agostic interaction, which can be employed for chemoselective boron transfer reactions. In this chapter, the inclination of this ligand class to change the chemoselectivity of HBCy₂ hydroboration toward carbonyl-containing substrates (in the presence of an alkene) is provided. Chapter 4 examines the preparation of the first unsaturated Cp*Ir(III) (Cp* = C₅Me₅) phosphoramidate complex for use in element-hydrogen (E-H) bond activation (E = H, C, Si, B). The syntheses of coordinatively unsaturated (E)-vinyloxy Cp*Ir(III) complexes, which are prepared from regioselective 1-alkyne C-H bond activation and O-phosphoramidation is discussed. This regioselectivity is completely inverted from that of free phosphoramidates, which undergo preferential N-alkylation. Finally, we illustrate how aminoborane (H₂B=NR₂) B-N bond rotation can be accessed using joint metal-ligand stabilization between Ir and a phosphoramidate coligand. All complexes were rigorously characterized using NMR spectroscopy, X-ray diffraction, as well as by DFT. Chapter 5 surmises a new protocol for rhodium-mediated ethylene amination (nitrogen-carbon bond formation) using diazenes (RN=NR) as the N-atom source. This work provides a “proof-of-principle” for the functionalization of simple C₂-synthons using easily handled nitrogen-sources, providing rhoda(III)heterocycles, which undergo [Rh]-N bond protonolysis to provide ethyl-substituted hydrazine complexes.

Multimodal Actuation in Magnetic Resonance Elastography Experiments
Creators: name: Gambacorta, Chiara
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Biological skeletal muscle tissue is subject to different modifications: as a matter of fact, its mechanical properties may be subject to changes correlated with diseases, such as Duchenne’s dystrophy and spasticity, or aging processes. These changes, especially those arising in the stiffness of the material, must be evaluated over time, in order to monitor the time-course of severe conditions and their potential response to therapeutic interventions. In recent years, scientists have developed new methods based on imaging techniques commonly used during diagnosis. These methods, named “elastographic”, are based on ultrasonic, optical and magnetic resonance imaging. Our research will focus on the Magnetic Resonance Elastography technique, which is often referred to as a “remote palpation technique”, able to give insights on the mechanical properties of a sample or tissue without being invasive. This method relies on the creation of MRI phase images following induced wave propagation in the tissue through mechanical excitation. Mechanical tissue properties can then be reconstructed with the use of mathematical inversion algorithms. This technique has been previously put to a test acquiring images resulting from geometrically focused (converging) out-of-imaging-plane (axial) excitation of the sample by means of a piezoelectric actuator. This research study aims to use the same MRE technique to identify changes in tissue mechanical properties under (in-plane) torsional deformations as well and to gain insight into the material properties variation from the comparison between the two kinds of actuation on the same sample. In the most innovative scenario, actuation of the sample, mimicking skeletal muscle tissue, will be achieved with the use of a stepper motor device, able to rotate on its axis thus transmitting torsional waves to the sample under examination. Images mapping the displacement field in a cross-sectional slice of the sample will be acquired by means of a Matlab sequence, able to trigger the acquisition process and to tune various parameters and filtering tools in order to obtain the so called “wave images”. Finally, an inversion algorithm named “Transformation Elastography” will be used to obtain stiffness values for the tissue both for the axial and the torsional excitation. We anticipate that the shape of wave images acquired through the stepper motor device will be substantially different from those that have already been acquired with excitation given by the piezo. These measures could prove to be useful in improving accuracy and efficiency of diagnosis, given the fact that they provide information about directional mechanical properties of the material that have not yet been examined (since they are provided by a novel type of actuation).

Lagrangian formulation of turbulent premixed combustion

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The Lagrangian point of view is adopted to study turbulent premixed combustion. The evolution of the volume fraction of combustion products is established by the Reynolds transport theorem. It emerges that the burned-mass fraction is led by the turbulent particle motion, by the flame front velocity, and by the mean curvature of the flame front. A physical requirement connecting particle turbulent dispersion and flame front velocity is obtained from equating the expansion rates of the flame front progression and of the unburned particles spread. The resulting description compares favorably with experimental data. In the case of a zero-curvature flame, with a non-Markovian parabolic model for turbulent dispersion, the formulation yields the Zimont equation extended to all elapsed times and fully determined by turbulence characteristics. The exact solution of the extended Zimont equation is calculated and analyzed to bring out different regimes.

description: We calculate small correction terms to gravitational potential near an asymmetric BPS brane embedded in a 5D AdS-Minkowski space in the context of supergravity. The normalizable wave functions of gravity fluctuations around the brane describe only massive modes. We compute such wave functions analytically in the thin wall limit. We estimate the correction to gravitational potential for small and long distances, and show that there is an intermediate range of distances in which we can identify 4D gravity on the brane below a crossover scale. The 4D gravity is metastable and for distances much larger than the crossover scale the 5D gravity is recovered.

Vehicle Mass Estimation Using a Total Least-Squares Approach

Publisher: name: Karlsruhe
Year: 2012

description: We introduce an incremental total least-squares vehicle mass estimation algorithm, based on a vehicle longitudinal dynamics model. Available control area network signals are used as model inputs and output. In contrast to common vehicle mass estimation schemes, where noise is only considered at the model output, our algorithm uses an errors-in-variables formulation and considers noise at the model inputs as well. A robust outlier treatment is realized as batch total least-squares routine and hence, the proposed algorithm works in a superior way on a broad range of vehicle acceleration. The results of six test runs on various vehicle masses show highly accurate mass estimation results on high and low dynamics of vehicular operation.

Heavy-neutrino decays at neutrino telescopes

description: It has been recently proposed that a sterile neutrino ν_h of mass m_h=40--80 MeV, mixing |U_{μh}|^2=10^{-3}--10^{-2}, lifetime τ_h \lsim 10^{-9} s, and a dominant decay mode (ν_h \to ν_μγ) could be the origin of the experimental anomalies observed at LSND, KARMEN and MiniBooNE. Such a particle would be abundant inside air showers, as it can be produced in kaon decays (K -> ν_h μ, K_L -> ν_h πμ). We use the Z-moment method to evaluate its atmospheric flux and the frequency of its decays inside neutrino telescopes. We show that the ν_h would imply around 10^4 contained showers per year inside a 0.03 km^3 telescope like ANTARES or the DeepCore in IceCube. These events would have a characteristic energy and zenith-angle distribution (E_ν= 0.1--10 TeV and θ< 90^o), which results from a balance between the reach of the heavy neutrino (that disfavors low energies) and a sizeable production rate and decay probability. The standard background from contained neutrino events (ν_e N \to e X and neutral-current interactions of high inelasticity) is 100 times smaller. Therefore, although it may be challenging from an experimental point of view, a search at ANTARES and IceCube could confirm this heavy-neutrino possibility.

Cognitive spectrum access, multimedia content delivery, and full-duplex relaying in wireless networks
Creators: name: Ma, Bojiang
Publisher: name: University of British Columbia
Year: 2017

description: Due to the growing number of wireless communication devices and emerging bandwidth-intensive applications, the demand of data usage is increasing rapidly. Utilizing various radio access technologies and multiple frequency bands in wireless networks can provide efficient solutions to meet the growing demand of data. These techniques are promising for the fifth generation (5G) wireless communication systems. However, to fully exploit their benefits, spectrum and spatial reuse, power saving, throughput and utility enhancement are crucial issues. In this thesis, we propose different resource allocation algorithms to address the aforementioned issues in wireless communication networks. First, we study the resource allocation problem for a hybrid overlay/underlay cognitive cellular network. We propose a hybrid overlay/underlay spectrum access mechanism to improve the spectrum and spatial reuse. We formulate the resource allocation problem as a coalition formation game among femtocell users, and analyze the stability of the coalition structure. We propose an efficient algorithm based on the solution concept of recursive core. The proposed algorithm achieves a stable and efficient spectrum allocation. Next, we study the resource allocation problem for multimedia content delivery in millimeter wave (mmWave) based home networks. We characterize different usage scenarios of multimedia content delivery. We formulate a joint power and channel allocation problem, which captures the spectrum and spatial reuse of mmWave communications, based on a network utility maximization framework. The problem is a non-convex mixed integer programming (MIP) problem. We reformulate the non-convex MIP problem into a convex MIP problem and propose a resource allocation algorithm based on the outer approximation method. We also develop an efficient heuristic algorithm which has a substantially lower complexity than the outer approximation based algorithm. Finally, we study full-duplex relay-assisted device-to-device (D2D) communication in mmWave based wireless networks. To design an efficient relay selection and power allocation scheme, we formulate a multi-objective combinatorial optimization problem, which balances the trade-off between power consumption and system throughput. The problem is transformed into a weighted bipartite matching problem. We then propose a joint relay selection and power allocation algorithm, which can achieve a Pareto optimal solution in polynomial time.

description: The thermodynamics of classical and quantum ideal gases based on the Generalized uncertainty principle (GUP) are investigated. At low temperatures, we calculate corrections to the energy and entropy. The equations of state receive small modifications. We study a system comprised of a zero temperature ultra-relativistic Fermi gas. It turns out that at low Fermi energy $\varepsilon_F$, the degenerate pressure and energy are lifted. The Chandrasekhar limit receives a small positive correction. We discuss the applications on configurations of compact stars. As $\varepsilon_F$ increases, the radius, total number of fermions and mass first reach their nonvanishing minima and then diverge. Beyond a critical Fermi energy, the radius of a compact star becomes smaller than the Schwarzschild one. The stability of the configurations is also addressed. We find that beyond another critical value of the Fermi energy, the configurations are stable. At large radius, the increment of the degenerate pressure is accelerated at a rate proportional to the radius.

Subjects: Uncategorized

description: Background: Failure to engage in difficult interprofessional conversations is a source of patient care errors. Nursing students rarely practice and get feedback on these “crucial conversations.” Methods: We developed and piloted a feedback tool for second-year nursing students to facilitate practice of difficult interprofessional conversations with standardized colleagues. Results: The tool identified opportunities for conflict resolution, specifically in the areas of problem identification, nonverbal communication, and respectful communication. A common challenge was providing a safe environment for these conversations. Conclusions: The development of an easy-to-use tool for difficult interprofessional conversations identifies specific areas for consistent feedback across a variety of situations.
Primary care providers’ attitudes and experiences recommending cancer screening to patients with Intellectual Disabilities
Creators: name: Breau, Genevieve Marie
Publisher: name: University of British Columbia
Year: 2017

description: Individuals with Intellectual Disabilities receive breast, cervical, and colorectal cancer screening at rates lower than the general population. The reasons for this disparity are poorly understood. Additionally, in the general population, a primary care provider’s recommendation for cancer screening is one of the key determinants of whether an individual obtains cancer screening. This mixed methods study explored the role of primary care providers in recommending cancer screening to patients with Intellectual Disabilities. First, 106 primary care providers (family physicians, family medicine residents, and nurse practitioner students from across British Columbia) were surveyed regarding their attitudes towards people with Intellectual Disabilities in general, and their anticipated likelihood of recommending breast, cervical, and colorectal cancer screening to fictional patients with Intellectual Disabilities presented in vignettes. In the second phase, 10 family medicine residents and two family physicians were interviewed regarding their experiences recommending cancer screening to patients with Intellectual Disabilities. The quantitative and qualitative analysis revealed that: (1) participants with negative attitudes towards the community inclusion of individuals with Intellectual Disabilities were less likely to recommend breast and colorectal cancer screening to fictional patients with Intellectual Disabilities; and (2) participants balance applying evidence-based guidelines with exercising clinical judgement to determine the best course of care for each patient, and this balance is situated within the larger medical environment that physicians practice within. In conclusion, this study determined that aspects of attitudes are related to cancer screening recommendations, but given that attitudes are one of many factors related to screening recommendations, future studies should not solely focus on this factor. Second, it appears that clinicians individualize care for all patients, and a patient’s Intellectual Disability is one of many factors considered prior to a screening recommendation. Finally, participants were aware of the evolving nature of cancer screening guidelines, and changed their practice accordingly as guidelines change. More research is needed to determine if these findings are applicable to more experienced primary care providers, given that the majority of participants in the interview phase were residents.

X-ray and Radio Constraints on the Mass of the Black Hole in Swift J164449.3+573451

Year: 2011

subject: FOS: Physical sciences

description: Swift J164449.3+573451 is an exciting transient event, likely powered by the tidal disruption of a star by a massive black hole. The distance to the source, its transient nature, and high internal column density serve to complicate several means of estimating the mass of the black hole. Utilizing newly-refined relationships between black hole mass, radio luminosity, and X-ray luminosity, and de-beaming the source flux, a weak constraint on the black hole mass is obtained: log(M/Msun) = 5.5 +/- 1.1 (1 sigma confidence). The confidence interval is determined from the current intrinsic scatter in the relation, which includes effects from X-ray variability and accretion modes. This mass range is broad, but it includes low values that are consistent with some variability arguments, and it safely excludes high mass values where it becomes impossible for black holes to disrupt stars. Future refinements in relationships between black hole mass, radio luminosity, and X-ray luminosity will be able to reduce the uncertainty in related mass estimates by a factor of two, making this technique comparable to estimates based on the M-sigma relationship. Possible difficulties in placing such events on the fundamental plane, a potential future test of their suitability, and uncertainties in mass stemming from variable X-ray emission are discussed. As near and longer-term survey efforts such as Pan-STARRS, LSST, LOFAR, the Square Kilometer Array, and eROSITA begin to detect many tidal disruption events, black hole mass estimates from combined X-ray and radio observations may prove to be very pragmatic.

description: It has been predicted that superconducting vortices should be electrically charged and that this effect is particularly enhanced for, high temperature superconductors.\cite{kho95,bla96} Hall effect\cite{hag91} and nuclear magnetic resonance (NMR) experiments\cite{kum01} suggest the existence of vortex charging, but the effects are small and the interpretation controversial. Here we show that the Abrikosov vortex lattice, characteristic of the mixed state of superconductors, will become unstable at sufficiently high magnetic field if there is charge trapped on the vortex core. Our NMR measurements of the magnetic fields generated by vortices in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+y}$ single crystals\cite{che07} provide evidence for an electrostatically driven vortex lattice reconstruction with the magnitude of charge on each vortex pancake of $\mathbf{\sim 2}$x$\mathbf{10^{-3} e}$, depending on doping, in line with theoretical estimates.\cite{kho95,kna05}

description: In this paper we conduct a systematic study of the granularity of the initial state of hot and dense QCD matter produced in ultra-relativistic heavy-ion collisions and its influence on bulk observables like particle yields, $m_T$ spectra and elliptic flow. For our investigation we use a hybrid transport model, based on (3+1)d hydrodynamics and a microscopic Boltzmann transport approach. The initial conditions are generated by a non-equilibrium hadronic transport approach and the size of their fluctuations can be adjusted by defining a Gaussian smoothing parameter $σ$. The dependence of the hydrodynamic evolution on the choices of $σ$ and $t_{start}$ is explored by means of a Gaussian emulator. To generate particle yields and elliptic flow that are compatible with experimental data the initial state parameters are constrained to be $σ=1$ fm and $t_{\rm start}=0.5$ fm. In addition, the influence of changes in the equation of state is studied and the results of our event-by-event calculations are compared to a calculation with averaged initial conditions. We conclude that even though the initial state parameters can be constrained by yields and elliptic flow, the granularity needs to be constrained by other correlation and fluctuation observables.

The Hartree-Fock exchange energy and potential are screened by means of the Yukawa potential as proposed by Bylander and Kleinman [Phys. Rev. B 41, 7868 (1990)] for the calculation of the electronic structure of solids with the screened-exchange local density approximation. Details of the formalism, which is based on the method of Massidda, Posternak, and Baldereschi [Phys. Rev. B 48, 5058 (1993)] for the unscreened Hartree-Fock exchange are given. The results for the transition-energy and structural properties of several test cases are presented. Results of calculations of the Cu electric-field gradient in Cu2O are also presented, and it is shown that the hybrid functionals are much more accurate than the standard local-density or generalized gradient approximations.

description: Solvent extraction is a primary technology for separating actinide from lanthanide elements in the recycling of used nuclear fuel. The transfer of metal ions from aqueous to organic phases underlies the process of solvent extraction. Ongoing developments of this process are aimed at optimizing the efficiency and kinetics of the separation and recovery of base, rare earth, and precious metals, as well as the reprocessing of spent nuclear fuel and nuclear waste. Although the interaction of metal ions with solutes at the organic-aqueous interface is likely to determine the efficiency and kinetics of extraction, little is known about the mechanism of ion transport across this interface. Numerous challenges are encountered, including those posed by demands of using synchrotron X-rays to probe a deeply buried liquid-liquid interface, the necessity to stabilize the ion distribution at the liquid-liquid interface, and the extraneous signals produced by ions in the neighboring bulk phases. Here I will report how these challenges are addressed as well as the X-ray findings, including an intermediate state at the liquid-liquid interface during forward extraction process of Er(III), Y(III) and Sr(II), and ion distribution at the liquid-liquid interface for the backward extraction process of Eu(III). I will also report the advances in the X-ray technique used in this study.

description: For complex sheet metal parts, multiple stamping stages are needed in a sequence. In today’s industry, intermediate parts are transferred between stages automatically by feeding as a strip (progressive die) or a blank (transfer die). Although progressive/transfer dies are highly automated, transfer system parameters need to be predefined. These parameters must ensure that the part is transferred to next stage quickly and safely. However, due to highly complex geometry and motion in the die system, these parameters are conventionally finalized manually according to designers’ experience. In this thesis, algorithms are proposed to optimize transfer system parameters in transfer die, according to the geometry and motion restrictions of the entire system. Two algorithms are proposed to complete a two-step optimization process. In the first step, the geometry of the die set and parts are analyzed. Based on Siemens NX software and customized kinematic model, motions of die components are simulated, an “Obstacle Map” is generated to record the potential collisions between parts (and grippers) and die set during the part transfer process. Obstacle map can be regarded as an inherent property of the entire die system geometry, which can be utilized not only for the optimization algorithm proposed in the second step, but also for future research. In the second step, with obstacle map, motions of the transfer system are analyzed. According to system motion capacity and freedom of modification in practice, transfer system parameters are optimized. The core of the algorithm in this step is to apply overlap between motions to reduce the transfer duration. Lift stroke and press stroke are also optimized when modifications are allowed. The optimized transfer system parameters result in improved strokes per minute, while all the obstacles in the obstacle map are bypassed. One case study for a typical transfer die system with 14 initial SPM is performed to show the effectiveness of the proposed algorithms. Four levels of optimization are conducted with increasing freedom of modification: initial speed -> maximum speed -> allow lift stroke modification -> allow press stroke modification. The results show that the proposed algorithms are valid, SPM can be improved (22.9 -> 26.52 -> 26.61 -> 27.99) in different situations. Some topics can be further addressed based on the works in this thesis, future works can focus on algorithm expansion to progressive die, and algorithm improvements for more complex cases.
Toward HDAC Isoform-Selective Inhibitors for the Treatment of Cancer and Infectious Diseases

description: Histone deacetylase (HDAC) proteins are the most studied and characterized erasers of post-translational modifications (PTMs) and play a pivotal role in the epigenetic machinery. HDAC activity and/or expression are dysregulated in disease; therefore, HDACs have emerged as promising therapeutic targets and five HDAC inhibitors have been approved by the Food and Drug Administration (FDA). These inhibitors are nonselective and their clinical outcomes are not optimal, and there is a growing body of preclinical and clinical evidence that the different HDAC isoforms have unique biological functions. This suggests that the efficacy and side effect profile of these inhibitors could be improved by targeting a single HDAC isoform in a specific disease state. In this thesis, rationale for and progress toward development of isoform-selective HDAC inhibitors are presented. First, investigation of the regulation of hepatitis B virus (HBV), a worldwide clinical problem, biosynthesis by class I and II HDACs is conducted and demonstrated an unconventional role of catalytically active HDAC5 in the regulation of HBV biosynthesis. HDAC5 expression increased both the stability and splicing of the HBV 3.5 kb RNA. These observations demonstrate the importance of specifically targeting HDAC5 for HBV therapeutic development and point to a broader role of HDAC5 in regulating RNA splicing and transcript stability. Second, the modeling, design, synthesis, and biological evaluation of a novel series of C1-substituted tetrahydroisoquinoline (TIQ)-based HDAC8 selective inhibitors are described. The cytotoxicity of the most potent and selective compounds was evaluated in neuroblastoma cell lines. Discovery of the novel TIQ chemotype paves the way for the development of HDAC8 selective inhibitors for therapeutic applications. A growing body of evidence, including the data presented in this thesis, demonstrate the many deleterious implications of using currently available nonselective inhibitors as therapies. Collectively, development of isoform-selective HDAC inhibitors could potentially overcome the many limitations of currently available nonselective inhibitors.

description: The chemical Fokker-Planck equation and the corresponding chemical Langevin equation are commonly used approximations of the chemical master equation. These equations are derived from an uncontrolled, second-order truncation of the Kramers-Moyal expansion of the chemical master equation and hence their accuracy remains to be clarified. We use the system-size expansion to show that chemical Fokker-Planck estimates of the mean concentrations and of the variance of the concentration fluctuations about the mean are accurate to order $Ω^{-3/2}$ for reaction systems which do not obey detailed balance and at least accurate to order $Ω^{-2}$ for systems obeying detailed balance, where $Ω$ is the characteristic size of the system. Hence the chemical Fokker-Planck equation turns out to be more accurate than the linear-noise approximation of the chemical master equation (the linear Fokker-Planck equation) which leads to mean concentration estimates accurate to order $Ω^{-1/2}$ and variance estimates accurate to order $Ω^{-3/2}$. This higher accuracy is particularly conspicuous for chemical systems realized in small volumes such as biochemical reactions inside cells. A formula is also obtained for the approximate size of the relative errors in the concentration and variance predictions of the chemical Fokker-Planck equation, where the relative error is defined as the difference between the predictions of the chemical Fokker-Planck equation and the master equation divided by the prediction of the master equation. For dimerization and enzyme-catalyzed reactions, the errors are typically less than few percent even when the steady-state is characterized by merely few tens of molecules.

description: Motivated by experimentally observed biocompatibility enhancement of nanoengineered cubic zirconia ZrO2 coatings to mesenchymal stromal cells, we have carried out computational analysis of the initial immobilization of one of known structural fragment of the adhesive protein (fibronectin) on the corresponding surface. We constructed an atomistic model of the zirconia nano-hillock of 3-fold symmetry based on AFM and TEM images. First-principle quantum-mechanical calculations show a substantial variation of electrostatic potential at the hillock due to the presence of surface features such as edges and vertexes. Using an implemented Monte Carlo simulated annealing method we found the orientation of the immobilized protein on the zirconia surface (both flat and nanostructured) and contribution of the each amino acid residue from the protein sequence to the adsorption energy. Accounting for the variation of the dielectric permittivity at the protein-implant interface we use a model distance-dependent dielectric function to describe the inter-atom electrostatic (Coulomb) interactions in the adsorption potential. We find that the initial immobilization of the rigid protein fragment on the nanostructured pyramidal ZrO2 surface is achieved with magnitude of adsorption energy larger than the one for the protein on the smooth (flat) surface. The strong attractive electrostatic interactions are a major factor in the enhanced adsorption at nanostructured surface that is absent in the case of adsorption on the flat uncharged surface. We show that the best electrostatic and steric fit of the protein to the inorganic surface corresponds to a minimum of the adsorption energy determined by the non-covalent interactions.
