description: In the present communication we report the preparation and characterizations of Langmuir and Langmuir-Blodgett films of a thiacyanine dye-dioctadecyl thiacyanine perchlorate (NK) mixed with Octadecyl trimethyl ammonium bromide (OTAB). The relationship between the molar ratio of OTAB and NK and the orientation of molecules at the air-water interface was investigated using surface pressure - area per molecule (π-A) isotherm. UV-Vis absorption and fluorescence spectroscopic investigations reveal that prominent J-aggregation of NK molecule was observed in the LB films lifted at higher surface pressure. This J-aggregation can be controlled by diluting the NK molecules with OTAB. It was observed that the J-aggregates of NK decayed to monomer and H-aggregates when the NK-LB film was exposed to a monochromatic light of wavelength 460 nm (Lambda max of J - aggregates).

description: Beyond the main sequence solar type stars undergo extensive mass loss, providing an environment where planet and brown dwarf companions interact with the surrounding material. To examine the interaction of substellar mass objects embedded in the stellar wind of an asymptotic giant branch (AGB) star, three dimensional hydrodynamical simulations at high resolution have been calculated utilizing the FLASH adaptive mesh refinement code. Attention is focused on the perturbation of the substellar mass objects on the morphology of the outflowing circumstellar matter. In particular, we determine the properties of the resulting spiral density wake as a function of the mass, orbital distance, and velocity of the object as well as the wind velocity and its sound velocity. Our results suggest that future observations of the spiral pattern may place important constraints on the properties of the unseen low mass companion in the outflowing stellar wind.

An examination of nurses’ practical judgments about the cognitive function of hospitalized older people
Creators: name: Moody, Elaine Marie
Publisher: name: University of British Columbia
Year: 2015

description: Nurses’ understandings of older patients’ cognitive function are central to how they determine and enact nursing care of older people in hospital, however, it remains unclear how nurses develop these understandings. The nursing literature concerned with how nurses determine actions in practice has begun to shift from instrumental views of reasoning to recognition that judgments are based on complex knowledge and are embedded in the particular context of nurses’ work. This study aimed to make explicit the complex, situated practical judgments of nurses about the cognitive function of older people in hospitals. The conceptual foundation of the study was informed by an integration of Aristotle’s notion of phronesis and Foucault’s understanding of power. A focused ethnographic study was conducted on two units in an urban general hospital over one year. Data were collected from 21 nurse informants through observations and interviews, and an analysis of documents used in their practice. Data analysis was guided by an analytic framework reflective of the conceptual framework. The findings showed that practical judgments about the cognitive function of older patients in hospital were structured through social relations, and nurses worked within that structure toward a complex understanding of patients’ cognitive function that would enable them to improve the situation of patients. Furthermore, ensuring safety and physiological stability emerged as the goals of nursing care related to the cognitive function of older patients and provided direction for practical judgments, including what evidence was sought and how it was used in deliberations about action. This articulation of nurses’ practical judgments about the cognitive function of older patients in hospital is a foundation for further inquiry into the context of nursing practice, educating new nurses on the complexity of nursing judgments and examining policy related to the structures guiding acute care nursing.

A kinetic study of the hydrogenation and dimerization of styrene and α-methylstyrene on Ni-Mo-S catalyst
Creators: name: Zhao, Xu
Publisher: name: University of British Columbia
Year: 2015

description: Oilsands bitumen upgrading to produce naphtha, among other products, is a feasible approach to increasing the supply of refined oil products. However, naphtha derived from bitumen is relatively unstable as it contains unsaturated hydrocarbons (5 vol% diolefins, 15 wt% aromatics). The unsaturated hydrocarbons tend to polymerize and form carbonaceous deposits on the catalyst during mild hydrotreating (~200 °C), resulting in pressure build-up in the reactor that causes the early shut down of the hydrotreating unit. This dissertation addresses diolefin hydrogenation and dimerization kinetics and gum formation over a commercial Ni-Mo-S hydrotreating catalyst. Two model compounds, styrene and α-methylstyrene (AMS), were selected to represent the diolefin present in the naphtha feed. Styrene reactions were based on orthogonal analysis with temperature (200, 225, 250 °C), diolefin concentration (3.7-7.4 wt%), and catalyst amount (0.5, 1, 2 g) varied. For the AMS reactions, a single variable test was applied by changing the AMS content (4.2-6.3 wt%) or temperature (200, 225 and 250 °C). The styrene and AMS hydrogenation kinetics were developed as 1st-order in reactant and 0-order in H₂, based on a simplified Langmuir-Hinshelwood (L-H) model. Pseudo 1st-order in model compound kinetics was employed for the dimerization reaction. The results revealed that the rate of hydrogenating or dimerizing styrene was faster than AMS due to steric hindrance effects. The activation energy for styrene and AMS hydrogenation was 45.3 and 87.7 kJ/mol, respectively. The activation energy for styrene dimerization was 99.6 kJ/mol. Additionally, the relationship between dimer content and gum formation at the end of the reaction indicated that higher dimer concentration increased gum content in styrene reactions. However, this relationship was not observed in AMS reactions because of steric hindrance effects. Finally, competitive reactions between olefins and diolefins were also examined. Cyclohexene hydrogenation to cyclohexane was initially suppressed by AMS hydrogenation to cumene. With longer reaction time (510 mins), the cyclohexane concentration exceeded cumene, suggesting that competitive hydrogenation occurred between the cyclohexene and AMS. Adding cyclohexene to the AMS significantly reduced the dimer content in the product possibly due to competitive adsorption on the acidic sites.

description: Introduction: The diagnosis of obstructive airway disease in diabetic patients may pose difficulties due the superimposition of restriction associated with diabetes on the pure obstructive pattern predominantly found in these patients. Aims: To evaluate the status of pulmonary function in diabetics (NIDDM - Non Insulin Dependent Diabetes Mellitus) with COPD (Chronic Obstructive Pulmonary Disease) or asthma. Methods: 45 Subjects (15 Diabetics with COPD, 15 Diabetics with Asthma & 15 healthy non diabetic, non smoking subjects with no chest complaints taken as the control group) underwent clinical evaluation, biochemical assessment of glycemic control, pulmonary function tests (Spirometry, DLCO and plethysmography lung volume measurements). Results: Spirometry showed pure obstruction in 20% patients whereas 66.67% patients had restriction which was confirmed in 20% on plethysmography. COPD patients had decreased DLCO/VA% (% Diffusion Lung Capacity of Carbon Monoxide corrected for Alveolar Volume) (P<0.0001), increased TLC % (Total Lung Capacity) (P<0.05), RV/TLC % (Residual Volume/ Total Lung Capacity %) (P<0.0001) along with increased severity of airflow limitation (measured by FEV1% (Forced Expiratory Volume in 1st second)) which correlated with DLCO/VA % (P<0.05). Asthmatics had near normal DLCO/VA%, TLC%, increased RV/TLC% (P<0.05) & also demonstrated correlation of FEV1% with duration of diabetes (P<0.05) and RV/TLC% (p<0.05) & also of FVC % (Forced Vital Capacity %) with duration of diabetes (P<0.05). Conclusion: Diabetics with COPD or asthma showed variable pulmonary function findings rather than the expected pure obstructive pattern and FEV1% and FVC% decline associated with diabetes might be responsible for these variable spirometric findings in addition to the severity of the airway disease.

description: Precise measurements of the radio emission by cosmic ray air showers require an adequate treatment of noise. Unlike to usual experiments in particle physics, where noise always adds to the signal, radio noise can in principle decrease or increase the signal if it interferes by chance destructively or constructively. Consequently, noise cannot simply be subtracted from the signal, and its influence on amplitude and time measurement of radio pulses must be studied with care. First, noise has to be determined consistently with the definition of the radio signal which typically is the maximum field strength of the radio pulse. Second, the average impact of noise on radio pulse measurements at individual antennas is studied for LOPES. It is shown that a correct treatment of noise is especially important at low signal-to-noise ratios: noise can be the dominant source of uncertainty for pulse height and time measurements, and it can systematically flatten the slope of lateral distributions. The presented method can also be transfered to other experiments in radio and acoustic detection of cosmic rays and neutrinos.

Three-dimensional numerical simulations of subaerial landslide generated waves
Creators: name: Clohan, William Daley
Publisher: name: University of British Columbia
Year: 2015

description: This research aims to advance the continuing effort of general purpose computational fluid dynamics model validation of subaerial landslide generated wave (SLGW) simulations. Specifically, using the open source program weakly compressible Smooth Particle Hydrodynamics model, DualSPHysics, three-dimensional simulations are quantitatively compared against a combination of physical model data and traditional general-purpose computational fluid dynamics, Flow-3D™, data. Many simulations were conducted to determine the effect of both numerical parametrization and numerical scheme prescriptions on SLGW accuracy. A systematic approach was taken to parse out insignificant physical processes using Flow-3D™ - specifically surface tension - and to determine the optimal numerical scheme settings that yield the most accurate results for both Flow-3D™ and DualSPHysics. From this research, it is found that DualSPHysics is able to accurately simulate both wave generation and wave propagation, but tends to over-predict the maximum wave run-up by about 70%. In contrast, Flow-3D™ was able to accurately simulate wave propagation, but under predicted wave generation by about 25% and over predicted the maximum wave run-up by about 40%. The question as to why both DualSPHysics and Flow-3D™ both over predict the maximum wave run-up during a SLGW simulation is still open. However, it is speculated that this due to a lack of either energy dissipation through air entrainment or eigenfrequency consideration’s.

description: In this paper we have reported the reaction kinetics of nano dimensional clay saponite and hectorite with an amphiphilic cation octadecyl rhodamine B (RhB) in hybrid Langmuir monolayer at the air-water interface. The surface pressure-molecular area (pi-A) isotherms were strongly influenced by the presence of clay with the lift-off area of the cationic amphiphile shifted to progressively larger area. In-situ infrared reflection absorption spectroscopy (IRRAS) was used to demonstrate the reaction kinetics. Time taken to complete the reaction kinetics for RhB-hectorite hybrid films is larger than RhB-saponite hybrid films. Atomic force microscopic images of hybrid Langmuir-Blodgett films give compelling visual evidence of the incorporation of clay platelets into the hybrid films and density of which increases with the progress of reaction kinetics.

description: The SU(3) octet SS-PP correlator and the difference of the singlet and octet scalar correlators are computed within Resonance Chiral Theory. The calculation is carried on up to the one-loop level, i.e., up to next-to-leading order in the 1/Nc expansion. Using the resonance expressions as interpolators between long and short distances, we demand the correlators to follow the high-energy power behavior prescribed by the operator product expansion and extract predictions for the low-energy constants. By adding more and more complicated operators to the hadronic action, our description is progressively improved, producing for the SS-PP correlator the chiral coupling estimates L_8(mu) = (1.0+- 0.4) 10^{-3} and C_{38}(mu) = (8+- 5) 10^{-6} for mu=770 MeV. Some first results for the S1 S1 - S8 S8 correlator are shown, like, for instance, the positivity of the spectral function for two-meson cuts, the high-energy constraints for each separate scalar form-factor and preliminary expressions for the L_6(mu) low-energy constant.

description: Dimensionality reduction is ubiquitous in analysis of complex dynamics. The conventional dimensionality reduction techniques, however, focus on reproducing the underlying configuration space, rather than the dynamics itself. The constructed low-dimensional space does not provide complete and accurate description of the dynamics. Here I describe how to perform dimensionality reduction while preserving the essential properties of the dynamics. The approach is illustrated by analyzing the chess game - the archetype of complex dynamics. A variable that provides complete and accurate description of chess dynamics is constructed. Winning probability is predicted by describing the game as a random walk on the free energy landscape associated with the variable. The approach suggests a possible way of obtaining a simple yet accurate description of many important complex phenomena. The analysis of the chess game shows that the approach can quantitatively describe the dynamics of processes where human decision-making plays a central role, e.g., financial and social dynamics.

We characterize them as maps of the A-type root lattice into a projective space such that images of vertices of any basic regular N-simplex are collinear. Such a characterization is manifestly invariant with respect to the corresponding affine Weyl group action, which leads to related symmetries of the Hirota--Miwa system.

description: We report optical imaging, optical and near-infrared polarimetry, and Spitzer mid-infrared spectroscopy of comet C/2007 N3 (Lulin). Polarimetric observations were obtained in R (0.676 micron) at phase angles from 0.44 degrees to 21 degrees with simultaneous observations in H (1.65 micron) at 4.0 degrees, exploring the negative branch in polarization. Comet C/2007 N3 (Lulin) shows typical negative polarization in the optical as well as a similar negative branch near-infrared wavelengths. The 10 micron silicate feature is only weakly in emission and according to our thermal models, is consistent with emission from a mixture of silicate and carbon material. We argue that large, low-porosity (akin to Ballistic Particle Cluster Aggregates) rather absorbing aggregate dust particles best explain both the polarimetric and the mid-infrared spectral energy distribution.

High temperature and high pressure cobalt cementation onto zinc dust
Creators: name: Zaheri, Shahram
Publisher: name: University of British Columbia
Year: 2015

description: Trace amounts of electrolyte cobalt during zinc electrowinning (EW) significantly decrease the current efficiency of the EW process by accelerating the parasitic hydrogen evolution reaction. The maximum tolerable level of cobalt in zinc EW can be as low as 0.1- 0.3 mg/L. The typical method to remove cobalt from zinc electrolyte, which is based on cementation onto zinc dust at approximately 85°C, is not an efficient process. It suffers from long retention times (2-3 hours) and high consumption of reagents; especially zinc dust. The aim of the present research was to study cobalt cementation at high temperature and high pressure (HT/HP) to accelerate the rate of cobalt removal and reduce the consumption of the reagents (zinc dust and activators). Experimental variables included temperature (85-150°C), pressure (0-100 psig), zinc dust dosage, zinc dust particle size, and activators (copper and antimony). Based on this research, the following results were obtained: 1. Increasing temperature had a significant effect on the rate of cobalt removal. The optimum temperature was found to be 125°C - temperature at which the target level of cobalt (0.1 mg/L) could be met in 20 min. 2. At 125°C and in the presence of 2.5 mg/L Sb and 45 mg/L Cu, 3.5 g/L zinc dust was found as the optimum zinc dust addition to lower cobalt concentration from the initial level of 15 mg/L to below 0.1 mg/L. 3. Smaller zinc particles showed better cobalt removal results, but the cement redissolution was also more severe with these particles. 4. The role of Sb in the activation system was more important than Cu. However, the best result in terms of the rate and extent of cobalt removal was achieved when both of the activators were added to the solution together. 5. As expected, increasing the overhead pressure of N₂ (tested at 85°C) did not alter the cobalt removal profile greatly. Also, the effect of increasing the partial pressure of H₂ (tested at 125°C, and above the amount generated in situ by the reaction) on cobalt removal was negligible.

description: We have explored our own innovative work about the design & development of internal location-identification system for mobile devices based on integration of RFID and wireless technology. The function of our system is based on strategically located passive RFID tags placed on objects around building which are identified using an RFID reader attached to a mobile device. The mobile device reads the RFID tag and through the wireless network, sends the request to the server. The server resolves the request and sends the desired location-based information back to the mobile device. We had addressed that we can go through the RFID technology for internal location identification (indoor), which provides us better location accuracy because of no contact between the tag and the reader, and the system requires no line of sight. In this paper we had also focused on the issues of RFID technologies i.e. Non-line-of-sight & High inventory speeds.

description: We propose and theoretically study a method for the stochastic realization of arbitrary quantum channels on multimode single-photon qudits. In order for our method to be undemanding in its implementation, we restrict our analysis to linear-optical techniques, vacuum ancillary states and non-adaptive schemes, but we allow for random switching between different optical networks. With our method it is possible to deterministically implement random-unitary channels and to stochastically implement general, non-unital channels. We provide an expression for the optimal probability of success of our scheme and calculate this quantity for specific examples like the qubit amplitude-damping channel. The success probability is shown to be related to the entanglement properties of the Choi-Jamiolkowski state isomorphic to the channel.

In particular, little is known about what leads practitioners to use ToL and how they experience the possibilities of its use in community contexts, both important knowledge(s) to support the understanding, deconstruction, improvement and future uptake of the methodology. Using semi-structured interviews, this inquiry sought the experiences of 19 practitioners, who work(ed) across 16 different countries using ToL in community contexts. The inquiry aimed, specifically, to understand the personal and professional impact of this work, the opportunities and challenges afforded by ToL, whether the practice differs from other practices, and what leads people to use ToL within community contexts. A Reflexive Thematic Analysis of the conversations with practitioners constructed three main themes: ‘Encountering Possibility’, ‘A Contrasting Way of Being and Doing’, and ‘Shared Humanity’. Eleven respective sub-themes were constructed, and together the analysis told a story that practitioners experience the methodology as one of ‘possibility’, different to other approaches in the way practitioners are able to work and be alongside others, sharing their stories in an authentic way and contributing to a joint humanity that leads to both connection and action. Implications for practitioners, the continued use of ToL, clinical psychology and the wider context were outlined. A critical appraisal and several possibilities for future inquiry were presented.

description: We study the properties of thermal radiation emitted by a thin dielectric slab, employing the framework of macroscopic fluctuational electrodynamics. Particular emphasis is given to the analytical construction of the required dyadic Green's functions. Based on these, general expressions are derived for both the system's Poynting vector, describing the intensity of propagating radiation, and its energy density, containing contributions from non-propagating modes which dominate the near-field regime. An extensive discussion is then given for thin metal films. It is shown that the radiative intensity is maximized for a certain film thickness, due to Fabry-Perot-like multiple reflections inside the film. The dependence of the near-field energy density on the distance from the film's surface is governed by an interplay of several length scales, and characterized by different exponents in different regimes. In particular, this energy density remains finite even for arbitrarily thin films. This unexpected feature is associated with the film's low-frequency surface plasmon polariton. Our results also serve as reference for current near-field experiments which search for deviations from the macroscopic approach.
Mechanical and molecular contribution of airway smooth muscle to airway hyperresponsiveness in asthma

Publisher: name: University of British Columbia

description: This thesis focuses on the mechanical and molecular role of airway smooth muscle (ASM) in asthma with the aim to determine the contribution of ASM to both asthma and airway hyperresponsiveness (AHR). The first three chapters involve studies probing the mechanical properties of tracheal ASM strips and how these may contribute to the development of AHR. They will aim to show that ASM can contribute to AHR without fundamental changes to the tissue. Specifically, the first chapter investigated the ASMs response to force oscillations mimicking breathing maneuvers under levels of activation that induce force adaptation, a phenomenon potentially seen in asthmatics. It shows that force adaptation can persist under conditions that mimic breathing maneuvers and therefore could contribute to AHR and ASM hypercontractility. The second chapter investigated the role of tone in limiting the strain imposed on ASM by breathing maneuvers and the subsequent response of ASM to those strains. The stiffening of muscle in response to agonist precedes force development and acts to decrease the strain applied to the ASM. As strain decreased, the effect on the muscle contractility was blunted. Interestingly, a prior history of oscillations induced a bronchoprotective effect in the strip and caused a two times greater decline in force than would normally be expected by the small strains indicating that prior DIs are effective in limiting the responsiveness of the ASM to agonist. The third chapter investigated whether the ASM is intrinsically responsible for the bronchoprotective effect of deep inspirations (DIs). This study showed that simulated prior DIs can increase the compliance of the muscle to subsequent DIs, and although the effect on a single strip of muscle is small, the effect at the whole lung level may be sufficient to explain the bronchoprotective effect of DIs. The final chapter describes the molecular phenotype of ASM in asthma at both the gene and protein level. Proteins involved in contraction were found not to be significantly altered in asthmatics; however a host of proteins involved in cytoskeletal structure were changed and could explain why asthmatic ASM is stiffer and less responsive to DIs.

description: In a planetary system with two or more well-spaced, eccentric, inclined planets, secular interactions may lead to chaos. The innermost planet may gradually become very eccentric and/or inclined, as a result of the secular degrees of freedom drifting towards equipartition of angular momentum deficit. Secular chaos is known to be responsible for the eventual destabilization of Mercury in our own Solar System. Here we focus on systems with three giant planets. We characterize the secular chaos and demonstrate the criterion for it to occur, but leave a detailed understanding of secular chaos to a companion paper (Lithwick & Wu, 2010). After an extended period of eccentricity diffusion, the inner planet's pericentre can approach the star to within a few stellar radii. Strong tidal interactions and ensuing tidal dissipation extracts orbital energy from the planet and pulls it inward, creating a hot Jupiter. In contrast to other proposed channels for the production of hot Jupiters, such a scenario (which we term "secular migration") explains a range of observations: the pile-up of hot Jupiters at 3-day orbital periods, the fact that hot Jupiters are in general less massive than other RV planets, that they may have misaligned inclinations with respect to stellar spin, and that they have few easily detectable companions (but may have giant companions in distant orbits). Secular migration can also explain close-in planets as low in mass as Neptune; and an aborted secular migration can explain the "warm Jupiters" at intermediate distances. In addition, the frequency of hot Jupiters formed via secular migration increases with stellar age. We further suggest that secular chaos may be responsible for the observed eccentricities of giant planets at larger distances, and that these planets could exhibit significant spin-orbit misalignment.

description: Nichtlineare Regelungen erfordern den Einsatz interpolierender Elemente zur Repräsentation von Streckenundloder Reglerverhalten. Künstliche Neuronale Netze haben sich als prinzipiell geeigneter Ansatz hierzu erwiesen, sind aber aufgrund ihres großen Ressourcenbedarfs ungeeignet für Applikationen, in denen nur einfache Rechnersysteme eingesetzt werden können. Dies ist bei Systemen in der Kraftfahrzeugtechnik der Fall. Delaunay-Netze, die in diesem Beitrag vorgestellt werden, stellen für niedrigdimensionale Problemstellungen eine Alternative dar. Es wird ein Algorithmus zur datengetriebenen Erstellung solcher Netze angegeben und in die aktuellen Arbeiten zur Generierungproblemangepaßter Modellstrukturen eingeordnet. Die mit dem vorgeschlagenen Verfahren erzielten Ergebnisse werden anhand eines vereinfachten Motormomentmodells erläutert.

description: The adsorption of a bottle-brush polymer end-grafted with one chain end of its backbone to a flat substrate surface is studied by Monte Carlo simulation of a coarse-grained model, that previously has been characterized in the bulk, assuming a dilute solution under good solvent conditions. Applying the bond fluctuation model on the simple cubic lattice, we vary the backbone chain length $N_b$ from $N_b=67$ to $N_b = 259$ effective monomeric units, the side chain length $N$ from N=6 to N=48, and the grafting density $σ=1$, i.e., parameters that correspond well to the experimentally accessible range. When the adsorption energy strength $ε$ is varied, we find that the adsorption transition (which becomes well-defined in the limit $N_b \rightarrow \infty$, for arbitrary finite $N$) roughly occurs at the same value $ε_c$ as for ordinary linear chains (N=0), at least within our statistical errors. Mean square end-to-end distances and gyration radii of the side chains are obtained, as well as the monomer density profile in the direction perpendicular to the adsorbing surface. We show that for longer side chains the adsorption of bottle-brushes is a two step process, the decrease of the perpendicular linear dimension of side chains with adsorption energy strength can even be non-monotonic. Also the behavior of the static structure factor $S(q)$ is analyzed, evidence for a quasi-two-dimensional scaling is presented, and consequences for the interpretation of experiments are discussed.

Configurable detection of SDC-causing errors in programs
Creators: name: Lu, Qining
Publisher: name: University of British Columbia

description: Silent Data Corruption (SDC) is a serious reliability issue in many domains, including embedded systems. However, current protection techniques are brittle, and do not allow programmers to trade off performance for SDC coverage. Further, many of them require tens of thousands of fault injection experiments, which are highly time-intensive. In this paper, we propose two empirical models, namely SDCTune and SDCAuto, to predict the SDC proneness of a program’s data. Both models are based on static and dynamic features of the program alone, and do not require fault injections to be performed. We then develop an algorithm using both models to selectively protect the most SDC-prone data in the program subject to a given performance overhead bound. Our results show that both models are accurate at predicting the SDC rate of an application. And in terms of efﬁciency of detection (i.e., ratio of SDC coverage provided to performance overhead), our technique outperforms full duplication by a factor of 0.78x to 1.65x with SDCTune model, and 0.62x to 0.96x with SDCAuto model.

description: Twelve common density functional methods and 7 basis sets for geometry optimization were evaluated on the accuracy of 1H/13C NMR chemical shift calculations for biaryls. For these functionals, 1H shifts calculations for gas phase optimized geometries were significantly less accurate than those for in-solution optimized structures, while 13C results were not strongly influenced by geometry optimization methods and solvent effects. B3LYP, B3PW91, mPW1PW91 and ωB97XD were the best-performing functionals with lowest errors; among 7 basis sets, DGDZVP2 and 6-31G(d,p) outperformed the others. The combination of these functionals and basis sets resulted in high accuracy with CMAEmin = 0.0327 ppm (0.76%) and 0.888 ppm (0.58%) for 1H and 13C, respectively. The selected functionals and basis set were validated when consistently producing optimized structures with high accuracy results for 1H and 13C chemical shift calculations of two other biaryls. This study highly recommends the IEFPCM/B3LYP, B3PW91, mPW1PW91 or ωB97XD/DGDZVP2 or 6-31G(d,p) level of theory for the geometry optimization step, especially the solvent incorporation, which would lead to high accuracy 1H/13C calculation. This work would assist in the fully structural assignments of biaryls and provide insights into in-solution biaryl conformations.
