Models and methods for portfolio selection
Creators: name: BONOMELLI, Marco
Publisher: name: Universit� degli Studi di Bergamo
Year: 2021

description: This work contributes to portfolio theory, the research field pioneered by Harry Markowitz in his seminal work ?Portfolio selection? trough the presentation of the mean-variance optimization concept proposing to adopt a double perspective in looking at assets: wealth and risk. According to Markowitz's, a portfolio is said to be efficient if, given a desired return level, it presents the lowest value of variance. The emerging objective is the trade-off optimization between risk and reward. Since then, several authors are engaged in the attempt of developing new theories and improving Markowitz's ideas and portfolio theory. In the present work two models are presented. Within the first one a Markov bi-variate process is adopted to characterize the evolution of wealth and volatility generated by the portfolios, then the introduction of stochastic volatility has been examined through Sharpe ratio optimization. Then, the performance indicators have been optimized with respect to a dynamic Sharpe Ratio and conditional to extreme values combination of wealth and volatility. The second model presents a new deviation measure based on quantile regression and it is used to develop a tracking error portfolio subject to enhancement with second order stochastic constraints. The idea behind the proposed framework is to detect a new asymmetrical indicator based on the ? parameter of the quantile regression. Second Order Stochastic dominance and enhancement are other constraints introduced to complete the model and to create a portfolio strategy suitable to over-perform the benchmark. This thesis contributes to portfolio theory research field through the definition of two new performance indicators: the first based on Sharpe ratio and the second one on quantile regression. Both the models out-perform the benchmark with respect to the proposed indicators. These findings make the work a promising starting point for new research developments.

description: Crystals of two mononuclear π-coordination compounds of copper(I) halide with 4-amino-1-propargylpyridinium cation – [(HC≡CCH2NC5H4NH2)CuBr2] (1) and [(HC≡CCH2NC5H4NH2)CuCl1.61 Br0.39] (2) – were obtained in the CuX–H2O–(HC≡CCH2NC5H4 NH2)Br system (HC≡CCH2N+C5H4NH2 is 4-amino-1-propargylpyridinium cation (app+), X=Cl or Br). The purity and identity of the synthesized compounds were verified by elemental analysis and IR spectroscopy. The compounds were structurally characterized using X-ray single crystal method and are isostructural. Both crystals are built of zwitterionic appCuX2 units, in which triple C≡C bond is coordinated to only one copper(I) ion. The Cu–m distance (m is the middle of the C≡C bond) is 1.933(5) and 1.917(3) Å for 1 and 2, respectively. The predisposition of copper(I) halides to coordination polymer self-assembly through Cu–X···Cu bridge formation is not realized in 1 and 2. However, the ≡C–H···Х and N–H···Х hydrogen bonds along with π–π stacking of 4-aminopyridinium groups compensate an absence of the structure-forming interaction Cu–X···Cu. DFT calculations of an electron structure of [(app)CuCl2] were carried out (the restricted Hartree–Fock (RHF) method with a 6–31 G* orbital basis set). Calculated values of the charge density distribution on atoms as well as the constructed molecular orbitals (MOs) are in agreement with stereochemical parameters of the (Cu(I)–(C≡C))-core of both coordination compounds.

description: The Kondo lattice model with substitutional disorder is studied with attention to the size of the Fermi surface and the associated Dingle temperature. The model serves for understanding heavy-fermion Ce compounds alloyed with La according to substitution Ce{x}La{1-x}. The Fermi surface is identified from the steepest change of the momentum distribution of conduction electrons, and is derived at low enough temperature by the dynamical mean-field theory (DMFT) combined with the coherent potential approximation (CPA). The Fermi surface without magnetic field increases in size with decreasing x from x=1 (Ce end), and disappears at such x that gives the same number of localized spins as that of conduction electrons. From the opposite limit of x=0 (La end), the Fermi surface broadens quickly as x increases, but stays at the same position as that of the La end. With increasing magnetic field, a metamagnetic transition occurs, and the Fermi surface above the critical field changes continuously across the whole range of x. The Dingle temperature takes a maximum around x=0.5. Implication of the results to experimental observation is discussed.

Disease-related misfolding of the myelin proteolipid protein [Thesis]
Creators: name: Roboti, Peristera
Publisher: name: figshare
Year: 2022
Subjects: Cell Biology

description: A wide range of mutations in the myelin integral plasma membrane proteolipid protein (PLP) are associated with dysmyelinating diseases of varying severity, and whilst missense mutations in PLP transmembrane domains cause severe disease, few such mutants result in a mild phenotype. The molecular pathology of such diseases has generally been attributed to endoplasmic reticulum (ER) retention of misfolded PLP, resulting in the induction of ER stress. However, the cellular mechanism(s) that control the observed phenotypic variations have not yet been elucidated. The work documented in this thesis established that the cellular fate of three distinct transmembrane missense mutants of PLP is differentially regulated by the ER quality control process upon stable inducible expression in HeLa cells. The novel, mild disease-associated G245A and W162L variants of PLP and the comparatively well- characterised, severe disease-causing A242V (msd) PLP mutant display distinct levels of ER retention and ubiquitin-proteasome-mediated degradation. Hence, the G245A variant of PLP shows a relatively tight ER retention phenotype and is quickly degraded by the proteasome, whilst W162L PLP is degraded more slowly but rather efficiently via both a proteasomal and a lysosomal pathway. In contrast to the mild disease-associated mutants, the more ‘aggressive’ msd variant is strictly retained in the ER and is significantly more stable. Notably, the expression of msd PLP is associated with rapid formation of mutant PLP oligomers in the ER, probably as the combined result of its ER retention and slow degradation. This premature oligomerisation of msd PLP appears to confer a toxic ‘gain-of-function’ to the misfolded protein, resulting in a prolonged induction of ER stress. These findings suggest a causal link between the accumulation of mutant PLP in the ER, premature PLP oligomerisation, ER stress, and disease severity. Hence, the rate of degradation of mutant PLP appears to provide the basis for the mechanisms that modulate the apparent phenotypic heterogeneity conferred by missense mutations in the encoding gene.

description: Mono-, di- and tri-nuclear Cu(II) and Zn(II) carboxylate complexes were synthesized and structurally characterized having general formulas [Cu2(biphenylacetate)4(DMSO)2] (1), [Zn(3,4-dichlororophenylacetate)2(1,10-phenanthroline)(H2O)] (2) and [Zn3(3,4-dichlororophenylacetate)6(2,2-bipyridine)2] (3). Complex 1 is a dinuclear Cu(II) complex with distorted square pyramidal geometry. Complex 2 is a mononuclear Zn(II) complex with distorted octahedral geometry while 3 is a tri-nuclear Zn(II) complex with octahedral (central Zn) as well as square pyramidal (terminal Zn) geometries. The stability of all complexes was checked by TGA and were found thermally stable. The solubility of the complexes was enhanced by using cationic (CTAB) and anionic (SDS) surfactants. Lower CMC values for SDS revealed good interaction as compared to CTAB. DNA-binding ability of the complexes was determined by UV–vis spectrophotometry and viscometry. All complexes bind with DNA effectively. The binding constant values from spectral analysis are 1.00(±0.02) × 104, 1.34(±0.01) × 105 M−1 and 1.11(±0.01) × 104 M−1 for 1–3, respectively. The DPPH-scavenging assay was performed by UV–vis spectrophotometry. All complexes showed good inhibition against the free radical. IC50 values for 1–3 are 109.98, 167.31 and 153.12 µM, respectively. The complexes were found to possess nice biological relevance.
Development of a hybrid simulation model for understanding community resilience to fuel disruption
Creators: name: Shen, Xuesi
Publisher: name: University of British Columbia
Year: 2017

description: Coastal and island communities in British Columbia are dependent on a multi-modal transportation network to support their basic needs, such as transportation of critical supplies. The network involves both land and marine transportation modes, various stakeholders and facilities. A broad range of potential disruptions, including natural disasters and human-induced events, threatens this system. Among all the critical supplies, fuel is of special importance. Fuel is required by not only the general consumers but also the emergency responses vehicles and facilities. The remote and semi-remote communities, which are at the end of the supply chain, will experience shortages of critical supplies if the regular transportation service is disrupted beyond the level that can be met using the local inventory. There is a critical need to understand fuel resilience and plan for potential fuel disruptions from the demand-side perspective. In this thesis, a hybrid model for simulating the community fuel supply, demand and inventory is presented. The development of the model is preceded by a detailed study of consumer behaviors and community fuel inventory strategies. In the model, a hypothesized hoarding mechanism to describe and predict consumer behaviors is established. Four disruption scenarios are created. Several strategies that may enhance the community resilience are proposed. The hybrid model is applied to the case study area, Powell River. It contributes to evaluate current fuel system resilience and examine the effectiveness of the proposed strategies. The simulation results demonstrate the importance of restraining possible consumer hoarding behaviors and conducting efficient inventory management. The concerns and recommendations from this thesis may lay the foundation for further exploration fuel resilience from the demand side.

description: This work describes the synthesis, characterization, cytotoxicity and antibacterial activity of three ligands derived from phenyl-oxadiazole-ethylenediamine and their platinum(II) and palladium(II) complexes. These compounds were characterized by elemental analysis, and Raman, IR, and NMR spectroscopies. We have prepared complexes with different substituents on the aromatic ring to provide influence in the antibacterial activity and cytotoxicity. The antibacterial activity was evaluated against Gram-positive bacteria Staphylococcus aureus (ATCC 25213), Staphylococcus epidermidis (ATCC 12228) and Gram-negative bacteria Escherichia coli (ATCC 11229) and Pseudomonas aeruginosa (ATCC 27853). The cytotoxicity was evaluated in two different tumor cell lines: mouse metastatic mammary adenocarcinoma (4T1), and murine colon cancer cells (CT26WT), and a non-tumor cell Baby Hamster Kidney (BHK-21). Based on the results obtained for the antibacterial and the cytotoxic activity it is possible to conclude that the presence of metal and groups NO2 and CF3 contributed to antibacterial activity with low cytotoxicity.

description: We study the temporal and spatial nonlinear dynamical evolution of a coupled triangular lattice crystal bilayer system where in one layer one excess free electron is injected while an excess positive charge, a hole, is created in the other. The atoms of each of the backbone lattices interact with anharmonic (short range) Morse potentials whereas the charges interact via (long range) Coulomb potentials. Computer simulations are provided of the possibilities offered by varying interlayer separation, strength of the Coulomb force between the charges and the diverse dynamical role played by excited solitons supersonically moving along crystallographic axes in one of the layers. Optimal conditions are identified for the occurrence of electron–hole pairs and for the more significant case of a boson-like electron–hole–soliton coupled compound, a new form of quasiparticle moving along the coupled bilayer system with no need of applying an external electric field.

description: The reaction of cobalt(II) acetate with 2-iodoterephthalic acid and 1,10-phenanthroline (phen) in N,N-dimethylformamide (DMF) leads to formation of two products, hexakis(N,N-dimethyl-formamide-κO)cobalt(II) bis(iodide) (1) and MOF [Co(TP)(phen)·2DMF·2H2O] (2), where TP is terephthalate dianion. Compound 1 crystallizes in the monoclinic space group Р2 1/с with cell parameters a = 14.2974(4) Å, b = 10.7983(4) Å, c = 20.6437(9) Å, V = 3183.23 Å3. The MOF was characterized by elemental analysis, infrared spectrometry, X-ray diffraction, scanning electron microscopy, thermogravimetry, and volumetric nitrogen adsorption/desorption. The sample has permanent porosity and a microporous structure with a large surface area corresponding to the adsorption type I. Thermolysis of 2 leads to the formation of nitrogen-doped carbon nanomaterials Co/CoO@C.

description: Substitution of Sb in FeSb$_2$ by less than 0.5% of Te induces a transition from a correlated semiconductor to an unconventional metal with large effective charge carrier mass $m^*$. Spanning the entire range of the semiconductor-metal crossover, we observed an almost constant enhancement of the measured thermopower compared to that estimated by the classical theory of electron diffusion. Using the latter for a quantitative description one has to employ an enhancement factor of 10-30. Our observations point to the importance of electron-electron correlations in the thermal transport of FeSb$_2$, and suggest a route to design thermoelectric materials for cryogenic applications.

description: Transition metal (T) nitroprussides form a family of coordination complexes with a wide structural diversity including 3 D, 2 D, 1 D, 0 D and ionic phases. Recently, a reversible thermally induced spin transition has been reported for 2 D ferrous nitroprussides stabilized through pyridine and its derivatives as pillars between neighboring layers. The aim of this study is to explore the possibility of obtaining analog solids with spin-crossover behavior using other molecules as pillars. In this contribution we are reporting the crystal structure, solved and refined from powder XRD data, for the resulting hybrid solids containing 1,3-oxazole, 1H-pyrazole, pyridazine, 3-pyridine-3-carboxaldheyde, imidazo[1,2-a]pyridine, and 4-(2-pyridin-4-ylethyl)pyridine as pillar molecules in the interlayer region. The XRD data were complemented with TG curves, and IR, Raman, Mössbauer spectra, and magnetic measurements as a source of complementary structural information. According to the Mössbauer spectra and magnetic data recorded in the temperature range of 5 to 300 K, no evidence of thermally induced spin-crossover was observed for the 2 D ferrous nitroprussides with these six organic ligands as pillars. Such behavior is in contrast with the one observed for pyridine and its derivatives and it is explained in terms of the local symmetry around the high spin Fe2+ ion, as revealed in the recorded Mössbauer spectra. This suggests that the spin-crossover behavior could be induced by introducing guest molecules, as adsorbed species, in the interlayer region to force to a higher symmetry for the iron ion coordination environment.

description: Intertrade duration of equities is an important financial measure characterizing the trading activities, which is defined as the waiting time between successive trades of an equity. Using the ultrahigh-frequency data of a liquid Chinese stock and its associated warrant, we perform a comparative investigation of the statistical properties of their intertrade duration time series. The distributions of the two equities can be better described by the shifted power-law form than the Weibull and their scaled distributions do not collapse onto a single curve. Although the intertrade durations of the two equities have very different magnitude, their intraday patterns exhibit very similar shapes. Both detrended fluctuation analysis (DFA) and detrending moving average analysis (DMA) show that the 1-min intertrade duration time series of the two equities are strongly correlated. In addition, both multifractal detrended fluctuation analysis (MFDFA) and multifractal detrending moving average analysis (MFDMA) unveil that the 1-min intertrade durations possess multifractal nature. However, the difference between the two singularity spectra of the two equities obtained from the MFDMA is much smaller than that from the MFDFA.

‘The principle of things’ : materiality and morality from Dutch still-life to Korean Chaekgeori
Creators: name: Irene, Choi
Publisher: name: University of British Columbia
Year: 2017

description: Elements from Dutch seventeenth-century still-lifes—the trompe-l’oeil motif of the painted curtain, vases of flowers, books and writing instruments—appear in a unique form of Korean painting on folding screens (Chaekgeori) during the late Joseon Dynasty (1392-1910). Connecting still-life paintings from the seventeenth-century Dutch Republic to the culture of eighteenth-century Joseon Korea, this thesis explores the natures of representation and vision and anxieties about material wealth and everyday objects in both the Protestant Netherlands and the Confucian Joseon dynasty. An important bridge between these two cultures is Qing (1644-1911) China, which had closer cultural contact with Europe than Korea during the eighteenth-century. During this period, Korean scholars were part of the same circles in the same environment in Beijing as European envoys and painters in residence at the Beijing Palace, such as the Italian Jesuit father Giuseppe Castiglione (郞世寧, 1688–1766), known for his illusionistic still-lifes. Thus, China, Korea and Europe were in direct contact, exchanging ideas on various fields of arts and sciences. Not only do I consider the still-life genre as a series of conventions in painting, but more importantly as a mode of exchange through and in representation that allows me to position late Joseon Korea within the larger artistic network of the early modern era between Europe and East Asia.

description: Aims: We investigate the behavior of the frequency-centered light curves expected within the standard model of Gamma Ray Bursts allowing the maximum electron energy to be a free parameter permitted to take low values. Methods: We solve the spatially averaged kinetic equations which describe the simultaneous evolution of particles and photons, obtaining the multi-wavelength spectra as a function of time. From these we construct the frequency-centered light curves giving emphasis in the X-ray and optical bands. Results: We show that in cases where the maximum electron energy takes low values, the produced X-ray light curves show a plateau as the synchrotron component gives its place to the Synhro Self-Compton one in the X-ray band.

description: An anthracene appended PET chemosensor, anthracene-9-carboxylic acid (3,4-dimethoxy-phenyl)-amide (A1), has been synthesized through condensation of corresponding acyl chloride and 3,4-dimethoxyaniline containing C = O and NH as receptors. The sensor A1 exhibited selective fluorescence turn-on behavior towards Cu2+ and Zn2+ ions in CH3CN. Cu2+ ions displayed 18-fold enhancement (Φ = 0.006→0.071) in the fluorescence spectrum of A1, which are otherwise well known for fluorescence quenching phenomenon. Moreover, A1 could easily discriminate between Zn2+ and Cd2+ ions, the two metal ions of similar nature. The Job’s plots analysis determined 2:1 (A1:Cu2+/Zn2+) stoichiometry between the sensor A1 and Cu2+/Zn2+ ions. The LOD values were calculated to be 1.75 and 3.08 µM for Cu2+ and Zn2+, respectively.

I.e. with global symmetry and breaking pattern $SU(n)_L\times SU(n)_R\to SU(n)_V$, $SU(2n)\to SO(2n)$ and $SU(2n)\to Sp(2n)$. We obtain fully analytical expressions for all these cases. We discuss the general structure of the amplitude and the structure of the possible intermediate channels for all three cases. We derive the expressions for the lowest partial wave scattering length in each channel and present some representative numerical results. We also show various relations between the different cases in the limit of large $n$.

description: Mononuclear dioxidomolybdenum(VI) complex with N-(dehydroacetic acid)-salicylic acid hydrazide having the formula [MoVIO2(dha-sah)(CH3OH)] is reported. The complex was synthesized by reaction of [MoVIO2(acac)2] with the said ligand in 1:1 metal-ligand ratio in methanol. The complex was characterized by elemental analysis, 1H and 13C NMR, FT-IR, electronic absorption spectroscopic and powdered X-ray diffractometry studies. Assignments of molecular geometrical parameters, molecular electrostatic potentials, nonlinear optical properties and frontier molecular orbitals of the titled complex were performed with the Gaussian 09 software package using density functional theory methods with B3LYP hybrid exchange-correlation functional and the standard LANL2DZ basis set. The experimental spectral analysis has been found in good agreement with the theoretical results. The overall study has revealed that the complex under investigation possesses a distorted octahedral geometry.

description: Internships are used as an educational tool to allow students to learn and understand the daily practices of a profession they are studying in university. To become a Certified Recreation Therapist Specialist (CTRS), students must complete an internship in a clinical setting under the supervision of a CTRS. The majority of studies that have examined internship outcomes have focused on the perspectives of professionals and educators. This qualitative study investigated the therapeutic recreation (TR) internship from the perspective of students. Participants of this study were seven graduates from Memorial University of Newfoundland (MUN) Bachelor of Recreation program who had completed their TR internships. Through semi-structured interviews, the main themes identified included; growth as a professional, meaningful relationships, and perceptions of learning. The results of this study suggest the need for further examination of higher education in therapeutic recreation.

description: Single-crystal XRD structure of binuclear tetranitrosyliron complex [Fe2(SR)2(NO)4] (1), R = 4-aminothiophenyl, has been described. The properties of 1 were studied by IR, Mössbauer, mass spectroscopy, and amperometry. Complex 1 was shown to form long-living nitrosyl intermediates in solution, which underlies its prolonged NO donor activity. In HeLa cells, 1 caused accumulation of NF-κB p50 but decreased the levels of NF-κB p65 in the nucleus, which led to inhibition of NF-κB dependent genes. The complex also induced increase of p53 protein levels and p21 gene activity, which led to the apoptotic cell death after G2/M cell cycle phase.

description: A new series of half-sandwich Ru(II)-arene complexes with phenanthroimidazole-triarylamine hybrid ligands were synthesized and scrutinized for DNA binding studies. The metal complexes were prepared via microwave-assisted synthesis with high yield and purity. The interaction of Ru(II)-arene complex with calf thymus DNA was studied by spectrophotometric methods. All six complexes exhibited significant interaction with CT-DNA. Methoxyphenyl-substituted metal complex showed the highest binding efficiency with a binding constant (Kb) of 5.053 × 104 M−1 due to its electron-rich nature. The methoxyphenyl group remarkably enhanced the interaction through stabilization of π-orbital of the metal complex which resulted in the efficient coupling. Phenyl- and thiophene-substituted ligands also showed good binding constants of 4.908 × 104 M−1 and 4.509 × 104 M−1, respectively. The absorption and ethidium bromide displacement studies declare that both the intercalation and groove binding is anticipated by these complexes. These Ru(II) complexes with phenanthroimidazole-triarylamine hybrid ligands can be realized as efficient DNA binding agents.

description: The rapidly changing science of clinical genetics and the complexity of its associated ethical, legal, and social (ELSI) issues call for novel approaches to information delivery and education of healthcare professionals and the public. Compared to traditional communication methodologies, arts-based methods offer a way to reach a wider variety of audiences and engage them in multi-sensory, experiential learning. Among the arts, theatre and the visual arts, including video, photography, and graphic medicine (comic books and graphic novels on medical topics), have thus far been the most carefully studied to evaluate their utility as communication tools for clinical genetics and science topics more generally. Although this literature collection explores a variety of media, we focus substantially here on studies of graphic medicine and theatre. Graphic medicine has particular promise as a communication tool for ELSI issues because its combination of written language and images can be more appealing and easier to understand than written explanations alone. Theatre can include both observing and participating in scenarios depicting the practice of clinical genetics, which is important in emphasizing that each person in a clinical scenario has an active role in any decision-making. This collection examines the potential of arts-based learning aids to convey scientific and medical information and explore attitudes about ELSI issues in clinical genetics, such as informed consent and research participation.

description: We present a non-perturbative renormalization of the bound state problem of n bosons interacting with finitely many Dirac delta interactions on two and three dimensional Riemannian manifolds using the heat kernel. We formulate the problem in terms of a new operator called the principal or characteristic operator. In order to investigate the problem in more detail, we then restrict the problem to one particle sector. The lower bound of the ground state energy is found for general class of manifolds, e.g., for compact and Cartan-Hadamard manifolds. The estimate of the bound state energies in the tunneling regime is calculated by perturbation theory. Non-degeneracy and uniqueness of the ground state is proven by Perron-Frobenius theorem. Moreover, the pointwise bounds on the wave function is given and all these results are consistent with the one given in standard quantum mechanics. Renormalization procedure does not lead to any radical change in these cases. Finally, renormalization group equations are derived and the beta-function is exactly calculated. This work is a natural continuation of our previous work based on a novel approach to the renormalization of point interactions, developed by S. G. Rajeev.

description: Epstein-Barr Virus is an important aetiological factor in the development of nasopharyngeal carcinoma (NPC). Serology suggested that besides NPC some other tumours located within the lymphoepithelial ring of the throat (Waldeyer's ring) might be associated with EBV. Nucleic-acid hybridizations were carried out to detect the presence of EBV-DNA in tumour biopsies derived from tonsillar carcinomas. We were able to demonstrate the presence of EBV-DNA in the tumour cells of two poorly differentiated carcinomas. We think that only a small fraction of tonsillar carcinomas is positive for EBV. The aetiologic relationship of EBV with tumours of Waldeyer's ring is discussed.

description: A heterogeneous 3-N,N,N-(II) Pd(OAc)2 catalyst was prepared from the reaction of Pd(OAc)2 with Si-Prn-N = C-Py-C = N-Prn-Si immobilized on graphene oxide (GO-Si-Prn-N = C-Py-C = N-Prn-Si-GO). The prepared catalyst was characterized by inductively coupled plasma optical emission spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, UV-vis spectroscopy, BET surface area, scanning electron microscopy, transmission electron microscopy, and thermogravimetric analysis. The catalyst was employed as a heterogeneous catalyst for carbonylative homo-coupling of aryl iodides and bromides under carbon monoxide gas-free condition. Cr(CO)6 was used as the carbon monoxide source and the desired symmetrical diaryl ketones were achieved in good to excellent yields. Moreover, the catalyst was reused up to five consecutive cycles without significant loss of activity.

description: A proper determination of the abundance gradient in the Milky Way requires the observation of objects at large galactiocentric distances. With this aim, we are exploring the planetary nebula population towards the Galactic Anticentre. In this article, the discovery and physico-chemical study of a new planetary nebula towards the Anticentre direction, IPHASX J052531.19+281945.1 (PNG 178.1-04.0), is presented. The planetary nebula was discovered from the IPHAS survey. Long-slit follow-up spectroscopy was carried out to confirm its planetary nebula nature and to calculate its physical and chemical characteristics. The newly discovered planetary nebula turned out to be located at a very large galactocentric distance (D_GC=20.8+-3.8 kpc), larger than any previously known planetary nebula with measured abundances. Its relatively high oxygen abundance (12+log(O/H) = 8.36+-0.03) supports a flattening of the Galactic abundance gradient at large galactocentric distances rather than a linearly decreasing gradient.
