description: This paper presents the first concerted look at low correlation sequence families over QAM constellations of size M^2=4^m and their potential applicability as spreading sequences in a CDMA setting. Five constructions are presented, and it is shown how such sequence families have the ability to transport a larger amount of data as well as enable variable-rate signalling on the reverse link. Canonical family CQ has period N, normalized maximum-correlation parameter theta_max bounded above by A sqrt(N), where 'A' ranges from 1.8 in the 16-QAM case to 3.0 for large M. In a CDMA setting, each user is enabled to transfer 2m bits of data per period of the spreading sequence which can be increased to 3m bits of data by halving the size of the sequence family. The technique used to construct CQ is easily extended to produce larger sequence families and an example is provided. Selected family SQ has a lower value of theta_max but permits only (m+1)-bit data modulation. The interleaved 16-QAM sequence family IQ has theta_max <= sqrt(2) sqrt(N) and supports 3-bit data modulation. The remaining two families are over a quadrature-PAM (Q-PAM) subset of size 2M of the M^2-QAM constellation. Family P has a lower value of theta_max in comparison with Family SQ, while still permitting (m+1)-bit data modulation. Interleaved family IP, over the 8-ary Q-PAM constellation, permits 3-bit data modulation and interestingly, achieves the Welch lower bound on theta_max.

description: We present the discovery of a planetary-mass companion to CFHTWIR-Oph 98, a low-mass brown dwarf member of the young Ophiuchus star-forming region, with a wide 200-au separation (1.46 arcsec). The companion was identified using Hubble Space Telescope images, and confirmed to share common proper motion with the primary using archival and new ground-based observations. Based on the very low probability of the components being unrelated Ophiuchus members, we conclude that Oph 98 AB forms a binary system. From our multi-band photometry, we constrain the primary to be an M9-L1 dwarf, and the faint companion to have an L2-L6 spectral type. For a median age of 3 Myr for Ophiuchus, fits of evolutionary models to measured luminosities yield masses of $15.4\pm0.8$ M$_\mathrm{Jup}$ for Oph 98 A and $7.8\pm0.8$ M$_\mathrm{Jup}$ for Oph 98 B, with respective effective temperatures of $2320\pm40$ K and $1800\pm40$ K. For possible system ages of 1-7 Myr, masses could range from 9.6-18.4 M$_\mathrm{Jup}$ for the primary, and from 4.1-11.6 M$_\mathrm{Jup}$ for the secondary. The low component masses and very large separation make this binary the lowest binding energy system imaged to date, indicating that the outcome of low-mass star formation can result in such extreme, weakly-bound systems. With such a young age, Oph 98 AB extends the growing population of young free-floating planetary-mass objects, offering a new benchmark to refine formation theories at the lowest masses.

description: Matrix Product States can be defined as the family of quantum states that can be sequentially generated in a one-dimensional system. We introduce a new family of states which extends this definition to two dimensions. Like in Matrix Product States, expectation values of few body observables can be efficiently evaluated and, for the case of translationally invariant systems, the correlation functions decay exponentially with the distance. We show that such states are a subclass of Projected Entangled Pair States and investigate their suitability for approximating the ground states of local Hamiltonians.

description: The GR@PPA event generator has been updated to version 2.7. This distribution provides event generators for $V$ ($W$ or $Z$) + jets ($\leq$ 4 jets), $VV$ + jets ($\leq$ 2 jets) and QCD multi-jet ($\leq$ 4 jets) production processes at $pp$ and $p\bar{p}$ collisions, in addition to the four bottom quark productions implemented in our previous work (GR@PPA\_4b). Also included are the top-pair and top-pair + jet production processes, where the correlation between the decay products are fully reproduced at the tree level. Namely, processes up to seven-body productions can be simulated, based on ordinary Feynman diagram calculations at the tree level. In this version, the GR@PPA framework and the process dependent matrix-element routines are separately provided. This makes it easier to add further new processes, and allows users to make a choice of processes to implement. This version also has several new features to handle complicated multi-body production processes. A systematic way to combine many subprocesses to a single base-subprocess has been introduced, and a new method has been adopted to calculate the color factors of complicated QCD processes. They speed up the calculation significantly.

Anodic polarisation behaviour of copper in chloride and bromide solutions containing benzotriazole, tolyltriazole, and methylbenzimidazole
Creators: name: Aben, Terence John
Publisher: name: University of British Columbia
Year: 2009

description: The interactions of oxide free copper surfaces with the organic chemicals benzotriazole, tolyltriazole and methylbenzimidazole were studied in solutions containing sodium chloride to elucidate the effect of modifying the molecular structure of benzotriazole on the inhibition of copper corrosion. All experiments were performed in solutions containing 1M NaCl. Experiments were performed using organic molecule concentrations of 8.39 x 10⁻³ M and 8.39 x 10⁻⁴ M and at pH values of 6.0 and 3.0. Potentiodynamic polarisation studies were used to gather information that was then compared to the established potential-pH equilibria. Polarisation scan rates of 1 mV/s and 0.2 mV/s were used. Inhibition of the anodic dissolution reactions was observed under all conditions studied using benzotriazole and tolyltriazole. The inhibition behaviour of benzotriazole and tolyltriazole are very similar and appear to use the same inhibition mechanism. Methylbenzimidazole was not found to produce an inhibiting effect. The potential-pH (E-pH) diagram for the Cu-Br⁻-H₂0 system was constructed from the available thermodynamic data. Polarisation scans were performed using copper in bromide solutions at pH 3.0 and 6.54 to confirm the behavioural redictions based on the E-pH diagram. To confirm the inhibition model proposed by Tromans et al.¹ on the behaviour of benzotriazole on oxide free copper surfaces in chloride media, experiments were performed in solution containing bromide and benzotriazole to eliminate the possibility of synergistic reactions with chloride, as well as to collaborate previous conclusions with a different set of thermodynamic data. Potentiodynamic polarisation studies were used to gather information on the behaviour of benzotriazole and tolyltriazole in sodium bromide solutions at pH values of 3.0 and 6.0.

description: We present first results from a deep (J = 18.7), wide-field (6.5 square degrees) infrared (ZYJHK) survey in the Upper Sco association conducted within the science verification phase of the UKIRT Infrared Deep Sky Survey Galactic Cluster Survey (GCS). Cluster members define a sequence well separated from field stars in the (Z-J,Z) colour-magnitude diagram. We have selected a total of 164 candidates with J = 10.5-18.7 mag from the (Z-J,Z) and (Y-J,Y) diagrams. We further investigated the location of those candidates in the other colour-magnitude and colour-colour diagrams to weed out contaminants. The cross-correlation of the GCS catalogue with the 2MASS database confirms the membership of 116 photometric candidates down to 20 Jupiter masses as they lie within a 2 sigma circle centred on the association mean motion. The final list of cluster members contains 129 sources with masses between 0.3 and 0.007 Msun. We extracted a dozen new low-mass brown dwarfs below 20 Mjup, the limit of previous surveys in the region. Finally, we have derived the mass function in Upper Sco over the 0.3-0.01 Msun mass range, best fit by a single segment with a slope of index alpha = 0.6+/-0.1, in agreement with previous determination in open clusters.

An interdisciplinary approach to identifying the sensory neuropeptide(s) that trigger vaginocervical stimulation-induced lordosis and analgesia.
Creators: name: Rivera, Jessica A.
Publisher: name: No Publisher Supplied
Year: 2021

description: Current pharmacotherapeutic options focus their site of pain modulation in the brain, and are often highly invasive and of low efficacy. This novel interdisciplinary research approach focused on gathering preliminary data to support an alternative approach to treating genital pain and sexual response by modulating sensory neurotransmitter activity in the periphery (i.e., at the first synapse in the sacral spinal cord). To this eventual end, the first step and the primary goal of this dissertation was to collect evidence that identifies the role(s) of one or more sensory neurotransmitters in the pelvic nerve, a nerve that heavily innervates genital areas. Our novel research approach utilized a rat model of lordosis (i.e., female mating posture, an index of sexual responsivity) to identify the sensory neurotransmitters located in the pelvic nerve. Our group hypothesized that the biological properties of sensory neuropeptides likely mediate lordosis and analgesia. To test their relevance, candidate neuropeptides (i.e., VIP, NPY, GAL, SOM, ENK, OT, SP, CCK, and CGRP) were put through corollary studies intended to gather converging evidence of sensory neuropeptide facilitation of lordosis, and/or mediation of analgesia. In experiment 1, our exhaustion paradigm was tested and supported. In experiment 2, candidate neuropeptide synthesis activity indicated changes in synthesis for GAL and VIP in response to lordosis-exhaustion, implicating these neuropeptides in lordosis. In experiment 3, candidate neuropeptide levels were analyzed using a unique quantitative approach to immunohistochemistry (IHC). Of the 9 candidates considered, only VIP and GAL IHC levels were significantly influenced by the analgesia-exhaustion condition, and NPY by lordosis-exhaustion. In experiment 4, there was no evidence of NPY facilitation of lordosis, yet there was evidence to support VIP and NPY mediation of VCS-induced analgesia. To corroborate these analgesic findings, respective receptor blockers were injected intrathecally, and only VIP receptor blocker significantly attenuated VCS- induced analgesia, but did not attenuate VCS-facilitated lordosis. The goal of this dissertation research was to identify sensory neuropeptides involved in the facilitation of lordosis, and/or mediation, of analgesia in response to VCS. Evidence was collected for VIP and NPY to support mediation of VCS-induced analgesia, and corroborating evidence was only obtained in the subsequent receptor blocker experiment for VIP.

description: We consider a simplified model of protein folding, with binary degrees of freedom, whose equilibrium thermodynamics is exactly solvable. Based on this exact solution, the kinetics is studied in the framework of a local equilibrium approach, for which we prove that (i) the free energy decreases with time, (ii) the exact equilibrium is recovered in the infinite time limit, and (iii) the folding rate is an upper bound of the exact one. The kinetics is compared to the exact one for a small peptide and to Monte Carlo simulations for a longer protein, then rates are studied for a real protein and a model structure.

Self-consistent renormalization theory of spin fluctuations in paramagnetic spinel LiV2O4

description: A phenomenological description for the dynamical spin susceptibility $χ({\bf q},ω;T)$ observed in inelastic neutron scattering measurements on powder samples of LiV$_2$O$_4$ is developed in terms of the parametrized self-consistent renormalization (SCR) theory of spin fluctuations. Compatible with previous studies at $T\to 0$, a peculiar distribution in ${\bf q}$-space of strongly enhanced and slow spin fluctuations at $q \sim Q_c \simeq$ 0.6 $Å^{-1}$ in LiV$_2$O$_4$ is involved to derive the mode-mode coupling term entering the basic equation of the SCR theory. The equation is solved self-consistently with the parameter values found from a fit of theoretical results to experimental data. For low temperatures, $T \lesssim 30$K, where the SCR theory is more reliable, the observed temperature variations of the static spin susceptibility $χ(Q_c;T)$ and the relaxation rate $Γ_Q(T)$ at $q\sim Q_c$ are well reproduced by those suggested by the theory. For $T\gtrsim 30$K, the present SCR is capable in predicting only main trends in $T$-dependences of $χ(Q_c;T)$ and $Γ_Q(T)$. The discussion is focused on a marked evolution (from $q \sim Q_c$ at $T\to 0$ towards low $q$ values at higher temperatures) of the dominant low-$ω$ integrated neutron scattering intensity $I(q; T)$.

description: Robot navigation through crowds poses a difficult challenge to AI systems, since the methods should result in fast and efficient movement but at the same time are not allowed to compromise safety. Most approaches to date were focused on the combination of pathfinding algorithms with machine learning for pedestrian walking prediction. More recently, reinforcement learning techniques have been proposed in the research literature. In this paper, we perform a comparative evaluation of pathfinding/prediction and reinforcement learning approaches on a crowd movement dataset collected from surveillance videos taken at Grand Central Station in New York. The results demonstrate the strong superiority of state-of-the-art reinforcement learning approaches over pathfinding with state-of-the-art behaviour prediction techniques.
Consumer responses to marketing activities: the role of brand concepts
Creators: name: Aksu, Gunben Ceren
Publisher: name: No Publisher Supplied
Year: 2021

description: Brands are faced not only with the decision of what to advertise, but also where to place their advertisements. Incorporating different brand concepts (i.e., abstract brand meanings), my dissertation investigates when and why different brands are helped or harmed by the placement or content of their marketing communications.My first essay examines message placement, delineating how consumers respond to heritage brands’ social media engagement. While prior research has demonstrated many positive consequences of brands’ social media use, the role of brand concept has remained unexplored. I propose and demonstrate in six studies, including two field datasets, that for heritage brands, engaging in social media leads to less favorable brand evaluations (i.e., brand dilution). This is because social media represents openness to change values, which are perceived to be inconsistent with the tradition values that heritage brands embody. Supporting the proposed role of inconsistency, this brand dilution effect is mitigated when heritage brands emphasize relatedness, a concept that better aligns with tradition values, and when they encourage dialecticism (i.e., acceptance of inconsistencies). By examining heritage brands, I identify both the cause and the solution for brand dilution stemming from social media engagement.My second essay examines message content by outlining the role of brand warmth in consumer responses to scarcity appeals (e.g., “only 10 available”). Prior research has examined the effect of scarcity appeals on promoted products, but their effect on the advertising brands has yet to be examined. I propose and demonstrate in four studies that using scarcity appeals leads to more positive brand evaluations, including higher behavioral intentions and more favorable attitudes, for high-warmth (vs. low-warmth) brands. This is because high-warmth brands are perceived to be well-intentioned, making the use of scarcity appeals feel less manipulative to consumers. Supporting the proposed mechanism, perceived good intentions mediate the effect of brand warmth on brand evaluations, and preventing consumers from inferring better intentions by priming the belief that scarcity appeals are profit-driven eliminates the observed effect. My work thus outlines a unique outcome of scarcity appeals, where such appeals can benefit warm brands.

description: We calculate the low-frequency current noise for AC biased mesoscopic chaotic cavities and diffusive wires. Contrary to what happens for the admittance, the frequency dispersion is not dominated by the electric response time (the "RC" time of the circuit), but by the time that electrons need to diffuse through the structure (dwell time or diffusion time). Frequency dispersion of noise stems from fluctuations of the Fermi distribution function that preserve charge neutrality. Our predictions can be verified with present experimental technology.

description: This paper presents HDGlab, an open source MATLAB implementation of the hybridisable discontinuous Galerkin (HDG) method. The main goal is to provide a detailed description of both the HDG method for elliptic problems and its implementation available in HDGlab. Ultimately, this is expected to make this relatively new advanced discretisation method more accessible to the computational engineering community. HDGlab presents some features not available in other implementations of the HDG method that can be found in the free domain. First, it implements high-order polynomial shape functions up to degree nine, with both equally-spaced and Fekete nodal distributions. Second, it supports curved isoparametric simplicial elements in two and three dimensions. Third, it supports non-uniform degree polynomial approximations and it provides a flexible structure to devise degree adaptivity strategies. Finally, an interface with the open-source high-order mesh generator Gmsh is provided to facilitate its application to practical engineering problems.

description: This paper explores the screech closure mechanism for different axisymmetric modes in shock-containing jets. While many of the discontinuities in tonal frequency exhibited by screeching jets can be associated with a change in the azimuthal mode, there has to date been no explanation for the existence of multiple axisymmetric modes at different frequencies. This paper provides just such an explanation. As shown in previous works, specific wavenumbers arise from the interaction of waves in the flow with the shocks. This provides new paths for driving upstream-travelling waves that can potentially close the resonance loop. Predictions using locally parallel and spatially periodic linear stability analyses and the wavenumber spectrum of the shock-cell structure suggest that the A1 mode resonance is closed by a wave generated when the Kelvin-Helmholtz mode interacts with the leading wavenumber of the shock-cell structure. The A2 mode is closed by a wave that arises due to interaction between the Kelvin-Helmholtz wave and a secondary wavenumber peak, which arises from the spatial variation of the shock-cell wavelength. The predictions are shown to closely match experimental data, and possible justifications for the dominance of each mode are provided based on the growth rates of the absolute instability.

description: We reply to remarks by Lang and Horanyi on the meaning of the notion of "electrosorption valency" used in I. Abou Hamad et al., Electrochim. Acta 50 (2005) 5518. It is concluded that, contrary to the assertion of Lang and Horanyi, the magnitude of the current in the external circuit upon adsorption of an ion of charge ze with partial charge transfer is indeed given by an electrosorption valency gamma such that |gamma e| < |ze|. We believe the conclusion of Lang and Horanyi to the contrary is the result of an excessively severe charge-neutrality requirement.

Racial liminality and American constructions of race: negotiating, imagining, and creating color lines in the 1890s
Creators: name: Pekarofski, Michael
Publisher: name: No Publisher Supplied

description: The decade of the 1890s was a period characterized by racial violence, the ongoing entrenchment of the Jim Crow state, and the legitimization of scientific racism. It was also a time when race and racial construction were in a considerable state of flux, formation, and development. Rather than constituting easily defined and clear-cut constructs, blackness, whiteness, and other categories often entailed complex, dynamic, and nuanced conversations and negotiations taking place in a variety of settings, texts, and historical situations. More often than not, such discourse centered around the presence of racially liminal figures, individuals or groups who did not fit neatly into specific racial categories. This liminality stemmed from the fact that their physicality, background, and identity remained unfixed or open to question. However, it was also created by the fact that racial categories themselves were often in a considerable state of flux, uncertainty, and formation. Real or imagined, individual or collective, racially liminal figures, appeared white, though that whiteness was often questioned, contested, and subject to change over time and space. Playing a central role in the evolving racial discourse, the presence of racially liminal figures often challenged and expanded the nation’s understanding of race and the nation’s understanding of itself. By examining the widespread and sustained concern with such racial in-betweenness, this project examines how Americans came to terms with race in the 1890s. Moreover, this study hopes to establish the centrality of the racially liminal figure to the ongoing process of racial construction and the maintenance of racial caste during this period. In the 1890s, racial liminality problematized, confounded, and contested the steady rise of cultural and political narratives which promoted white supremacist, racial separatist, and scientific racist agendas. Though racially liminal people, racially liminal bodies, and racial liminality in the abstract were often used in the service of an anti-racist agenda, white supremacists were more than capable of using racial liminality to serve their own goals and objectives. This study analyzes the multi-faceted ways racially liminal figures shaped, contested, and problematized the formation and solidification of a fixed binary of race.

description: We have performed a search over 3440 deg$^2$ of Epoch 1 (2017-2019) of the Very Large Array Sky Survey to identify unobscured quasars in the optical ($0.2 < z < 3.2$) and obscured active galactic nuclei (AGN) in the infrared that have brightened dramatically in the radio over the past one to two decades. These sources would have been previously classified as "radio-quiet" quasars based on upper limits from the Faint Images of the Radio Sky at Twenty Centimeters survey (1993-2011), but they are now consistent with "radio-loud" quasars ($L_{\rm 3\,GHz} = 10^{40 - 42} \,\, {\rm erg} \,{\rm s}^{-1}$). A quasi-simultaneous, multiband ($\sim1-18$ GHz) follow-up study of 14 sources with the VLA has revealed compact sources ($<0.1^{\prime \prime}$ or $<1$ kpc) with peaked radio spectral shapes. The high-amplitude variability over decadal timescales at 1.5 GHz (100% to $>$2500%), but roughly steady fluxes over a few months at 3 GHz, are inconsistent with extrinsic variability due to propagation effects, thus favoring an intrinsic origin. We conclude that our sources are powerful quasars hosting compact/young jets. This challenges the generally accepted idea that "radio-loudness" is a property of the quasar/AGN population that remains fixed on human timescales. Our study suggests that frequent episodes of short-lived AGN jets that do not necessarily grow to large scales may be common at high redshift. We speculate that intermittent but powerful jets on subgalactic scales could interact with the interstellar medium, possibly driving feedback capable of influencing galaxy evolution.

HD 65949: The Highest Known Mercury Excess Of Any CP Star?

description: ESO spectra of HD 65949 show it to be unlike any of the well-known types within its temperature range $\approx$ 13600K. It is neither a silicon, nor a mercury-manganese star, though it has a huge Hg II line at $λ$3984. We estimate $\log({\rm Hg/H}) + 12.0 \approx 7.4$. This is higher than any published stellar mercury abundance. HD 65949 is a member of a nearby open cluster, NGC 2516, which is only slightly older than the Pleiades, and has been of recent interest because of its numerous X-ray emission stars, including HD 65949 itself, or a close companion. A longitudinal magnetic field of the order of -290 Gauss at the 4.7~$σ$ level was very recently diagnosed from accurate circular spectropolarimetric observations with FORS 1 at the VLT. The spectral lines are sharp, allowing a thorough identification study. Second spectra of Ti, Cr, and Fe are rich. Mn II is well identified but not unusually strong. Numerous lines of S II and P II are found, but not Ga II. The resonance lines of Sr II are strong. While many Y II lines are identified, and Nb II is very likely present, {\it no} Zr II lines were found. Xe II is well identified. Strong absorptions from the third spectra of the lanthanides Pr, Nd, and Ho are present, but lines from the second spectra of lanthanides are extremely weak or absent. Among lines from the heavier elements, those of Pt II are clearly present, and the heaviest isotope, $^{198}$Pt, is indicated. The uncommon spectrum of Re II is certain, while Os II and Te II are highly probable. Several of the noted anomalies are unusual for a star as hot as HD 65949.

Implication of the B -> rho rho data on the B -> pi pi puzzle

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We point out that the B -> rho rho data have seriously constrained the possibility of resolving the B -> pi pi puzzle from the large observed B^0 -> pi^0 pi^0 branching ratio in the available theoretical approaches. The next-to-leading-order (NLO) contributions from the vertex corrections, the quark loops, and the magnetic penguin evaluated in the perturbative QCD (PQCD) approach have saturated the experimental upper bound of the B^0 -> rho^0 rho^0 branching ratio, and do not help. The NLO PQCD predictions for the B^0 -> rho^\mp rho^\pm and B^\pm -> rho^\pm rho^0 branching ratios are consistent with the data. The inclusion of the NLO jet function from the soft-collinear effective theory into the QCD-improved factorization approach, though enhancing the B^0 -> pi^0 pi^0 branching ratio sufficiently, overshoots the bound of the B^0 -> rho^0 rho^0 branching ratio, and deteriorates the predictions for the B^\pm -> pi^0 K^\pm and B^0 -> pi^\mp K^\pm direct CP asymmetries.

Free actions on surfaces that do not extend to arbitrary actions on 3-manifolds

description: We provide the first known example of a finite group action on an oriented surface $T$ that is free, orientation-preserving, and does not extend to an arbitrary (in particular, possibly non-free) orientation-preserving action on any compact oriented 3-manifold $N$ with boundary $\partial N = T$. This implies a negative solution to a conjecture of Domínguez and Segovia, as well as Uribe's evenness conjecture for equivariant unitary bordism groups. We more generally provide sufficient conditions that imply infinitely many such group actions on surfaces exist. Intriguingly, any group with such a non-extending action is also a counterexample to the Noether problem over the complex numbers $\mathbb{C}$. In forthcoming work with Segovia we give a complete homological characterization of those finite groups admitting such a non-extending action, as well as more examples and non-examples. We do not address here the analogous question for non-orientation-preserving actions.

description: We study intermediate--z SNe Ia using the empirical physical diagrams which enable to learn about those SNe explosions. This information can be very useful to reduce systematic uncertainties of the Hubble diagram of SNe Ia up to high z. The study of the expansion velocities and the measurement of the ratio $\mathcal{R}$(\SiII) allow to subtype those SNe Ia as done for nearby samples. The evolution of this ratio as seen in the diagram $\mathcal{R}$(\SiII)--(t) together with $\mathcal{R}$(\SiII)$_{max}$ versus (B-V)$_{0}$ indicate consistency of the properties at intermediate z compared with local SNe. At intermediate--z, the expansion velocities of Ca II and Si II are similar to the nearby counterparts. This is found in a sample of 6 SNe Ia in the range 0.033$\leq z \leq$0.329 discovered within the {\it International Time Programme} (ITP) of {\it Cosmology and Physics with SNe Ia} during the spring of 2002. Those supernovae were identified using the 4.2m William Herschel Telescope. Two SNe Ia at intermediate z were of the cool FAINT type, one being a SN1986G--like object highly reddened. The $\mathcal{R}$(\SiII) ratio as well as subclassification of the SNe Ia beyond templates help to place SNe Ia in their sequence of brightness and to distinguish between reddened and intrinsically red supernovae. This test can be done with very high z SNe Ia and it will help to reduce systematic uncertainties due to extinction by dust. It should allow to map the high-z sample into the nearby one.

Lattice and Electronic properties of VO$_2$ with the SCAN(+$U$) approach

description: Appropriate consideration of the electron correlation is essential to reproduce the intriguing metal-insulator transition accompanying the Peierls-type structural transition in VO$_2$. In the density functional theory-based approach, this depends on the choice of the exchange-correlation functional. Here, using a newly developed strongly constrained and appropriately norm (SCAN) functional, we investigate the lattice and electronic properties of the metallic rutile phase of VO$_2$ ($R$-VO$_2$) from the first-principles calculations. We also explored the role of the Coulomb correlation $U$. By adding $U$, we found that the phonon instability properly describes the Peierls-type distortions. The orbital-decomposed density of states presents the orbital selective behavior with the SCAN+$U$, which is susceptible to the one-dimensional Peierls distortion. Our results suggest that even with the SCAN functional, the explicit inclusion of the Coulomb interaction is necessary to describe the structural transition of VO$_2$.
