description: We compute, from first-principles, the frequency of the E2g, Gamma phonon (Raman G-band) of graphene, as a function of the charge doping. Calculations are done using i) the adiabatic Born-Oppenheimer approximation and ii) time-dependent perturbation theory to explore dynamic effects beyond this approximation. The two approaches provide very different results. While, the adiabatic phonon frequency weakly depends on the doping, the dynamic one rapidly varies because of a Kohn anomaly. The adiabatic approximation is considered valid in most materials. Here, we show that doped graphene is a spectacular example where this approximation miserably fails.

description: Consider the focussing cubic nonlinear Schrödinger equation in $R^3$: $$ iψ_t+Δψ= -|ψ|^2 ψ. $$ It admits special solutions of the form $e^{itα}ϕ$, where $ϕ$ is a Schwartz function and a positive ($ϕ>0$) solution of $$ -Δϕ+ αϕ= ϕ^3. $$ The space of all such solutions, together with those obtained from them by rescaling and applying phase and Galilean coordinate changes, called standing waves, is the eight-dimensional manifold that consists of functions of the form $e^{i(v \cdot + Γ)} ϕ(\cdot - y, α)$. We prove that any solution starting sufficiently close to a standing wave in the $Σ= W^{1, 2}(R^3) \cap |x|^{-1}L^2(R^3)$ norm and situated on a certain codimension-one local Lipschitz manifold exists globally in time and converges to a point on the manifold of standing waves. Furthermore, we show that $\mc N$ is invariant under the Hamiltonian flow, locally in time, and is a centre-stable manifold in the sense of Bates, Jones. The proof is based on the modulation method introduced by Soffer and Weinstein for the $L^2$-subcritical case and adapted by Schlag to the $L^2$-supercritical case. An important part of the proof is the Keel-Tao endpoint Strichartz estimate in $R^3$ for the nonselfadjoint Schrödinger operator obtained by linearizing around a standing wave solution.

description: Abstract

This study examines Bitcoin and Ethereum's dynamic interactions and causal relationships. Our research uses many advanced statistical and econometric methods. These include Augmented Dickey-Fuller (ADF) tests for stationarity, GARCH models for volatility, VAR models for multivariate analysis, Granger causality tests for predictive relationships, and co-integration analysis for long-term associations. Our study found significant skewness and kurtosis in both cryptocurrencies' return distributions, highlighting the need for specialized statistical methods. Bitcoin and Ethereum returns have a strong positive correlation, indicating their interdependence. The analysis of volatility spillover underscores their interdependence. Bitcoin exhibits volatility clustering and Ethereum's volatility is influenced by past shocks. Granger causality tests show a one-way relationship between Bitcoin and Ethereum. Co-integration analysis shows that the two entities have lasting relationships despite their instability. The above findings find use in risk management, portfolio diversification, trading strategies, and policy decisions in the ever-changing cryptocurrency market. Despite limitations, this study lays the groundwork for future cryptocurrency research. Risk managers, investors, academics, and policymakers can use these insights to improve their cryptocurrency strategies and decisions.

description: Demonstrated for a digital image sensor based camera is a calibration target optimized method for finding the Camera Response Function (CRF). The proposed method uses localized known target zone pixel outputs spatial averaging and histogram analysis for saturated pixel detection. Using the proposed CRF generation method with a 87 dB High Dynamic Range (HDR) silicon CMOS image sensor camera viewing a 90 dB HDR calibration target, experimentally produced is a non-linear CRF with a limited 40 dB linear CRF zone. Next, a 78 dB test target is deployed to test the camera with this measured CRF and its restricted 40 dB zone. By engaging the proposed minimal exposures, weighting free, multi-exposure imaging method with 2 images, demonstrated is a highly robust recovery of the test target. In addition, the 78 dB test target recovery with 16 individual DR value patches stays robust over a factor of 20 change in test target illumination lighting. In comparison, a non-robust test target image recovery is produced by 5 leading prior-art multi-exposure HDR recovery algorithms using 16 images having 16 different exposure times, with each consecutive image having a sensor dwell time increasing by a factor of 2. Further validation of the proposed HDR image recovery method is provided using two additional experiments, the first using a 78 dB calibrated target combined with a natural indoor scene to form a hybrid design target and a second experiment using an uncalibrated indoor natural scene. The proposed technique applies to all digital image sensor based cameras having exposure time and illumination controls. In addition, the proposed methods apply to various sensor technologies, spectral bands, and imaging applications.

description: The in-plane thermal conductivity $κ$ of the layered superconductor Cu$_x$TiSe$_2$ was measured down to temperatures as low as $T_c$/40, at $x$ = 0.06 near where the CDW order vanishes. The absence of a residual linear term at $ T \to 0$ is strong evidence for conventional s-wave superconductivity in this system. This is further supported by the slow magnetic field dependence, also consistent with a single gap, of uniform magnitude across the Fermi surface. Comparison with the closely related material NbSe$_2$, where the superconducting gap is three times larger on the Nb 4$d$ band than on the Se 4$p$ band, suggests that in Cu$_{0.06}$TiSe$_2$ the Se 4$p$ band is below the Fermi level and the Ti 3$d$ band is alone responsible for the superconductivity.

description: It is known that certain quantum cosmological models present quantum behavior for large scale factors. Since quantization can suppress past singularities, it is natural to inquire whether quantum effects can prevent future singularities. To this end, a Friedmann-Robertson-Walker quantum cosmological model dominated by a phantom energy fluid is investigated. The classical model displays accelerated expansion ending in a Big Rip. The quantization is performed in three different ways, which turn out to lead to the same result, namely there is a possibility that quantum gravitational effects could not remove the Big Rip.

Symbolism and identity in the synagogue: toward the design of a contemporary synagogue in an urban context
Creators: name: Chodikoff, Ian Franklin
Publisher: name: University of British Columbia
Year: 2009

description: Identifying the difficulties of the synagogue as a built form necessitates an initial analysis of its development throughout its long and varied history. The project focusses on the cultural significance of a synagogue, its function and its representation as a place of religious, educational and social assembly. Examining the history of the synagogue and the development of its three main functions serves to assist in leading toward the development of a design for a contemporary synagogue placed well within the public view. The site of the project is situated on the fringe of the historic area of Yaletown in Vancouver and adjacent to recent developments along Pacific Boulevard and the Downtown South area. The intent of the building's design is to express the function and identity of the building to the. general population as well as the Jewish community. The synagogue has a variety of functions and the design approach attempts to express the overlapping of the educational, religious and social relationships. The synagogue as a building type is problematic. The conscious avoidance of overt Jewish symbols such as the Menorah, the Star of David, or the tablets of Moses increases the level of difficulty with regards to the building's ability to be identified as a synagogue. The design approach isolates the significance of the Ark of the Covenant which holds the sacred Torah scrolls. The religious sanctuary envelops the Ark and the library, in turn envelops the sanctuary. The social hall is situated off of street level while the classrooms and meeting rooms overlook a courtyard above the sanctuary. While being conscious of how volumes can complement and contrast each other, spaces are created by overlapping them with one another allowing symbiotic relationships to occur within the synagogue itself. The external expression is realized through a series of planes which serve to provide the synagogue with a form of protection; an armature which breaks open and reveals the variety of functions inside. Overall, the intent of the design is to provide both the Jewish and non-Jewish public with an appreciation of the complexities involved in the formation and expression of a Jewish institution serving as a centre to the broad range of functions and interests within the community.

description: Comets are small bodies thought to contain the most pristine material in the solar system. However, since their formation 4.5 Gy ago, they have been altered by different processes. While not exposed to much electromagnetic radiation, they experience intense particle radiation. Galactic cosmic rays and solar energetic particles have a broad spectrum of energies and interact with the cometary surface and subsurface; they are the main source of space weathering for a comet in the Kuiper Belt or in the Oort cloud; and also affect the ice prior to the comet agglomeration. While low energy particles interact only with the cometary surface, the most energetic ones deposit a significant amount of energy down to tens of meters. This interaction can modify the isotopic ratios in cometary ices and create secondary compounds through radiolysis, such as O2 and H2O2 (paper II: Maggiolo et al., 2020). In this paper, we model the energy deposition of energetic particles as a function of depth using a Geant4 application modified to account for the isotope creation process. We quantify the energy deposited in cometary nucleus by galactic cosmic rays and solar energetic particles. The consequences of the energy deposition on the isotopic and chemical composition of cometary ices and their implication on the interpretation of cometary observations, notably of 67P/Churyumov Gerasimenko by the ESA/Rosetta spacecraft, will be discussed in Paper II.
The evaluation of near-shore current components on macro-tidal beaches: Field analysis and numerical approach

description: With increasing population growths on the Coastal fringes, it is becoming more important to be able to successfully model the coastal processes. To monitor the erosion of the beach profile requires information about the nearshore currents for sediment transport calculations. However, due to the large tidal ranges of macro -tidal beaches, the current will be a complex combination of both wave -induced and tidal current components, with the total current varying with time and distance along the intertidal zone.
In this thesis, FORTRAN programs for the numerical modelling of tidal currents will be developed (WAVECHT and SURFCW respectively). Also, a statistical program (STATCW) for the evaluation of the intertidal currents andwave conditions from field data will be detailed.
Finally, a preliminary evaluation of the current components at the sub -tidal and inter -tidal zones for a macro -tidal beach on the Capricorn Coast will be made.The evaluation will be based on the subjective interpretation of the reducedfield results from STATCW, with the aid of the prediction models WAVECHT, and SURFCW. Particular focus will be on the relative importance of the longshore tidal current component on the nearshore currents for macro -tidal regions.

description: By taking the particle triaxial-rotor model with variable moment of inertia, we investigate the energy spectra, the deformations and the single particle configurations of the nuclei $^{183,185,187}$Tl systemically. The calculated energy spectra agree with experimental data quite well. The obtained results indicate that the aligned bands observed in $^{183,185,187}$Tl originate from the $[530]{1/2}^{-}$, $[532]{3/2}^{-}$, $[660]{1/2}^{+}$ proton configuration coupled to a prolate deformed core, respectively. Whereas, the negative parity bands built upon the ${9/2}^{-}$ isomeric states in $^{183,185,187}$Tl are formed by a proton with the $[505]{9/2}^{-}$ configuration coupled to a core with triaxial oblate deformation, and the positive parity band on the ${13/2}^{+}$ isomeric state in $^{187}$Tl is generated by a proton with configuration $[606]{13/2}^{+}$ coupled to a triaxial oblate core.

Linking soft excess in ultraluminous X-ray sources with optically thick wind driven by supercritical accretion

description: Supercritical accretion onto compact objects may drive massive winds that are nearly spherical, optically thick, and Eddington limited. Blackbody emission from the photosphere is the direct observational signature of the wind. Here we investigate whether or not it can explain the soft emission component seen in the energy spectra of ultraluminous X-ray sources (ULXs). Based on high-quality XMM-Newton spectra of 15 ULXs, we find that the soft component can be modeled as blackbody emission with a nearly constant luminosity, and the 5 known pulsating ULXs (PULXs) in the sample display a blackbody luminosity among the lowest. These are consistent with the scenario that the soft emission originates from the photosphere of the optically thick wind. However, the derived blackbody luminosity for PULXs is significantly above the Eddington limit for neutron stars. A possible explanation is that a considerable fraction of the optically thick wind roots in the inner accretion flow, where the radiative flux could exceed the Eddington limit due to a reduced scattering cross-section or enhanced radiation transfer with magnetic buoyancy. Based on a wind model, the inferred mass accretion rate in these standard ULXs overlaps but is on average lower than that in luminous and very soft X-ray sources, which are also candidates with supercritical accretion. Alternatively, it cannot be ruled out that the soft emission component is a result of the hard component, e.g., via down-scattering in a cool medium, as a weak correlation may exist between them.

description: This study focuses on the analysis of the interest margin (MI) of Italian banks listed on the MTA (Mercato Telematico Azionario) of the Italian Stock Exchange, for the years 2021 and 2022. The net interest margin is represented by the difference between interest income on uses and interest expense on collection operations. This indicator is widely recognized as a measure of operational efficiency within credit broking. In the context of this analysis, the trend of the inflation rate in the euro area and of the ECB reference rates will also be examined, for the period from 2013 to 2022. The restrictive monetary policy of the ECB, which began during of 2022 and continued with a certain intensity, was in our opinion one of the main causes of the increase in the interest margin. The scientific literature on the subject of interest margin and negative nominal interest rates will be examined. Finally, we will explore the evolution of the composition of financial instruments held by retail customers at Italian banks over this period.

description: We investigate the effect of nonlinearity in a system described by an adiabatically evolving Hamiltonian. Experiments are conducted in a three-core waveguide structure that is adiabatically varying with distance, in analogy to the STIRAP process in atomic physics. In the linear regime, the system exhibits an adiabatic power transfer between two waveguides which are not directly coupled, with negligible power recorded in the intermediate coupling waveguide. In the presence of nonlinearity the behavior of this configuration is drastically altered and the adiabatic light passage is found to critically depend on the excitation power. We show how this effect is related to the destruction of the dark state formed in the STIRAP configuration.

description: Reinforcement learning has shown great promise in robotics thanks to its ability to develop efficient robotic control procedures through self-training. In particular, reinforcement learning has been successfully applied to solving the reaching task with robotic arms. In this paper, we define a robust, reproducible and systematic experimental procedure to compare the performance of various model-free algorithms at solving this task. The policies are trained in simulation and are then transferred to a physical robotic manipulator. It is shown that augmenting the reward signal with the Hindsight Experience Replay exploration technique increases the average return of off-policy agents between 7 and 9 folds when the target position is initialised randomly at the beginning of each episode.

These are constructed from quark propagators calculated with the overlap Dirac operator on quenched gauge configurations at beta = 6. By comparing baryon states that differ in their diquark content, we find evidence for enhanced correlation in the scalar diquark channel, as favored by quark models. We also summarize earlier results for diquark masses in the Landau gauge, casting them in a form more easily compared with subsequent studies.

description: Toroidal rotation is well known to play significant roles in the edge transport and L-H transition dynamics of tokamaks. Our recent calculation finds that a sufficiently strong localized toroidal rotation can directly bring out the formation of edge pressure pedestal with reversed magnetic shear that is reminiscent of an H-mode plasma, purely through the effects of toroidal rotation on the tokamak MHD equilibrium itself. In particular, the enhanced edge toroidal rotation enables a substantial peaking of the parallel current profile near edge in higher $β$ regimes, which leads to the flattening or reversal of the local $q$ (safety factor) profile. Here the formation of pressure pedestal along with the reversed magnetic shear region is shown to be the natural outcome of the MHD tokamak equilibrium in a self-consistent response to the presence of a localized toroidal rotation typically observed in H-mode or QH-mode.

We find a broad peak in specific heat which is insensitive to magnetic field at a temperature of 1.5 K with a value of 2.65 J/mol K. The magnetic susceptibility at 5 T continues to increase down to 2 K, the lowest temperature measured. The data suggest that the Sm spin system may be an ideal realization of the frustrated Heisenberg antiferromagnet on the square lattice.

description: The algebra $\mathcal H:= H_{1,ν}(I_2(2m+1))$ of observables of the Calogero model based on the root system $I_2(2m+1)$ has an $m$-dimensional space of traces and an $(m+1)$-dimensional space of supertraces. In the preceding paper we found all values of the parameter $ν$ for which either the space of traces contains a~degenerate nonzero trace $tr_ν$ or the space of supertraces contains a~degenerate nonzero supertrace $str_ν$ and, as a~consequence, the algebra $\mathcal H$ has two-sided ideals: one consisting of all vectors in the kernel of the form $B_{tr_ν}(x,y)=tr_ν(xy)$ or another consisting of all vectors in the kernel of the form $B_{str_ν}(x,y)=str_ν(xy)$. We noticed that if $ν=\frac z {2m+1}$, where $z\in \mathbb Z \setminus (2m+1) \mathbb Z$, then there exist both a degenerate trace and a~degenerate supertrace on $\mathcal H$. Here we prove that the ideals determined by these degenerate forms coincide.

description: In this paper we analyze transport through a double dot system connected to two external leads. Imagining each dot possessing a single active level, we model the system through a generalization of the Anderson model. We argue that this model is exactly solvable when certain constraints are placed upon the dot Coulomb charging energy, the dot-lead hybridization, and the value of the applied gate voltage. Using this exact solvability, we access the zero temperature linear response conductance both in and out of the presence of a Zeeman field. We are also able to study the finite temperature linear response conductance. We focus on universal behaviour and identify three primary features in the transport of the dots: i) a so-called RKKY Kondo effect; ii) a standard Kondo effect; and iii) interference phenomena leading to sharp variations in the conductance including conductance zeros. We are able to use the exact solvability of the dot model to characterize these phenomena quantitatively. While here we primarily consider a double dot system, the approach adopted applies equally well to N-dot systems.

description: I discuss the physics of non-Abelian plasmas which are locally anisotropic in momentum space. Such momentum-space anisotropies are generated by the rapid longitudinal expansion of the matter created in the first 1 fm/c of an ultrarelativistic heavy ion collision. In contrast to locally isotropic plasmas anisotropic plasmas have a spectrum of soft unstable modes which are characterized by exponential growth of transverse chromo-magnetic/-electric fields at short times. This instability is the QCD analogue of the Weibel instability of QED. Parametrically the chromo-Weibel instability provides the fastest method for generation of soft background fields and dominates the short-time dynamics of the system. The existence of the chromo-Weibel instability has been proven using diagrammatic methods, transport theory, and numerical solution of classical Yang-Mills fields. I review the results obtained from each of these methods and discuss the numerical techniques which are being used to determine the late-time behavior of plasmas subject to a chromo-Weibel instability.

description: Excited Si^+ and Fe^+ species are routinely observed in the host environment of gamma-ray burst (GRB) afterglows, but are not commonly seen in other extragalactic locations. Their presence signals unusual properties in the gaseous environment of these GRB hosts that arise either as a result of the intense ionizing radiation of the afterglow or through collision excitation in a dense cloud. In particular, the photon pumping scenario has explicit expectations for temporal variation in the strength of the excited lines, owing to the decline in the ionizing flux of the GRB afterglow. We analyze afterglow spectra of GRB 020813 obtained in two epochs of ~16 hours apart, and examine transitions from the first excited state of Fe^+ at J=7/2 in these two sets of data. We report a significant decline by at least a factor of five in the equivalent width of the FeII 2396 transition, the strongest from the J=7/2 state. We perform a Monte-Carlo analysis and determine that this temporal variation is present at more than 3sigma level of significance. This observation represents the first detection in the temporal variation of the excited Fe+ states in the GRB host ISM, a direct influence of the burst itself on its environment. We further estimate that the Fe^+ gas resides in 50-100 pc from the afterglow, based on the afterglow lightcurve and the presence and absence of the excited FeII 2396 in the two-epoch observations.

description: We report on the synthesis of highly oriented a-axis CrO2 films onto (0001) sapphire by atmospheric pressure CVD from CrO3 precursor, at growth temperatures down to 330 degree Celsius, i.e. close to 70 degrees lower than in published data for the same chemical system. The films keep the high quality magnetic behaviour as those deposited at higher temperature, which can be looked as a promising result in view of their use with thermally sensitive materials, e.g. narrow band gap semiconductors.

description: In this paper, we introduce and study the graph of the groups of mappings on a set X with respect to function compositions that cannot be subsets of the symmetric groups S3 and S4. Furthermore, we investigate some of the justifications on these groups that have studied in graph theory, and we got good results. Moreover, we consider the graph of these groups by fixed points and study some properties of it.

description: Researches on Indonesian named entity (NE) tagger have been conducted since years ago. However, most did not use deep learning and instead employed traditional machine learning algorithms such as association rule, support vector machine, random forest, naïve bayes, etc. In those researches, word lists as gazetteers or clue words were provided to enhance the accuracy. Here, we attempt to employ deep learning in our Indonesian NE tagger. We use long short-term memory (LSTM) as the topology since it is the state-of-the-art of NE tagger. By using LSTM, we do not need a word list in order to enhance the accuracy. Basically, there are two main things that we investigate. The first is the output layer of the network: Softmax vs conditional random field (CRF). The second is the usage of part of speech (POS) tag embedding input layer. Using 8400 sentences as the training data and 97 sentences as the evaluation data, we find that using POS tag embedding as additional input improves the performance of our Indonesian NE tagger. As for the comparison between Softmax and CRF, we find that both architectures have a weakness in classifying an NE tag.
Visible cities: a Gallery of Urban Design in downtown Vancouver
Creators: name: Chan, Walton Fan
Publisher: name: University of British Columbia
Year: 2009

description: In my Directed Studies I looked at how architecture can make the experience of time more immediate. This can be done by the use of light that marks the passage of time and the variability of the outside world; the unfolding of and movement through a building's spaces; the juxtaposition of permanent and changing elements; and in the choice of materials and how they wear over time. To explore these ideas, I choose as my project a Gallery of Urban Design for Vancouver. The Gallery would give students and professionals as well as the interested public the chance to learn about the complexity and richness of cities. The site is a vacant 100' x 120' lot on the SW corner of Robson and Homer, across Robson St. from the new Public Library. This area is consolidating as an arts and entertainment district, and a smaller-scale cultural venue would complement larger institutions like the Library, Ford Theatre, BC Place, etc. The site is at a strategic corner of this district, with strong connections to the rest of downtown. Right now, this district is an odd mix of empty lots and large object buildings that dominate most or all of a city block, most of which turn their backs on the sidewalk. The result is a barren and uninviting streetscape. What's missing is a finer grain to knit together these large monuments, the kind of grain seen in nearby Yaletown and on Robson St. The site of the Gallery, across from the Library, has the chance to extend Robson St.'s rhythm, and also to enclose and define Library Square. The Gallery itself is the heart of the project. There are four gallery spaces devoted to different themes: the City's Origins, the City Rises, the City in Crisis, and the City Renewed. In each there is a permanent exhibit on Vancouver around which changing exhibits about other cities are organised. The areas for permanent exhibits are marked by a change in the flooring, from polished concrete to wood. For visitors, the gallery spaces, each a variation on the same palette of materials and light, unfold piece by piece as they move through them, always with glimpses ahead of what's to come and views back to where they've been. The dimension of time is involved in understanding this sequence, and emphasised in the in-between spaces that thicken the transitions. The simple materials serve as a reference for the changing qualities of light that are used to mark a centre and to draw the visitor forward, to imply stability and movement, in a rhythm of light and dark that ends with the dramatic light and city views of the last gallery.
Nightwood: Nightwood
Creators: name: Stewart, Christine Anne
Publisher: name: University of British Columbia
Year: 2009

description: The novel Nightwood (1936) stalks proximity through a textual realignment of written history, through a writing alive to its own contingencies and through an insistent rearticulation of its signifiers. It struggles to circumscribe into discourse that which has been foreclosed from signification. It releases language from the melancholic stupor of normative prose and initiates a widescale process of resignification. This thesis is an exploration of these textual acts, acts which push language beyond the confines of normalizing discourse into performative, structural and philosophical sites of investigation and reconstruction, toward the open production of new meaning.

description: We describe the data acquisition system for the MuLan muon lifetime experiment at Paul Scherrer Institute. The system was designed to record muon decays at rates up to 1 MHz and acquire data at rates up to 60 MB/sec. The system employed a parallel network of dual-processor machines and repeating acquisition cycles of deadtime-free time segments in order to reach the design goals. The system incorporated a versatile scheme for control and diagnostics and a custom web interface for monitoring experimental conditions.

Fast Algorithm to Calculate Density of States

description: An algorithm to calculate the density of states, based on the well-known Wang-Landau method, is introduced. Independent random walks are performed in different restricted ranges of energy, and the resultant density of states is modified by a function of time, F(t)=1/t, for large time. As a consequence, the calculated density of state, gm(E,t), approaches asymptotically the exact value gex(E) as 1/sqrt(t), avoiding the saturation of the error. It is also shown that the growth of the interface of the energy histogram belongs to the random deposition universality class.

Spectroscopic study of the HII regions in the NGC 1232 galaxy

description: NGC 1232 is a face-on spiral galaxy that serves as an excellent laboratory for the study of star formation due to its proximity. Recent studies have revealed interesting features about this galaxy: X-ray observations suggest that it recently collided with a dwarf galaxy, however, no apparent remnant is observed. Here we search for evidence of this collision. We used long-slit optical spectra in two different positions obtained with the Goodman spectrograph at the SOAR telescope. We detected 18 HII regions in the north-south direction and 22 HII regions in the east-west direction and a background galaxy, NGC 1232B, for which we present the first redshift measurement and spectral analysis. We used the stellar population fitting technique to study the underlying stellar population and to subtract it from the spectra to measure the emission lines. The emission lines were used to determine the extinction, electron density, chemical abundance, and the star-formation rate gradient of NGC 1232. As is common in spiral galaxies, we found a stellar population gradient with older populations at the central regions and younger ones towards the outskirts, along with a negative oxygen abundance gradient of -0.16 dex/re. Due to the difficulty of measuring important emission lines, the number of objects for the abundance gradient is small, but there is a hint that this galaxy has a broken gradient profile, with a drop towards the center. If the collision caused any disturbance in the galaxy, we believe it would be small and hard to detect with a limited number of objects. From all the other measurements, we found no deviations from a typical spiral galaxy and no significant difference between different directions in the galaxy. The stellar population and emission line analysis of NGC 1232B suggest that it is a starburst galaxy.
