description: In this paper we give a new example of duality between fragmentation and coagulation operators. Consider the space of partitions of mass (i.e., decreasing sequences of nonnegative real numbers whose sum is 1) and the two-parameter family of Poisson--Dirichlet distributions $\operatorname {PD}(α,θ)$ that take values in this space. We introduce families of random fragmentation and coagulation operators $\mathrm {Frag}_α$ and $\mathrm {Coag}_{α,θ}$, respectively, with the following property: if the input to $\mathrm {Frag}_α$ has $\operatorname {PD}(α,θ)$ distribution, then the output has $\operatorname {PD}(α,θ+1)$ distribution, while the reverse is true for $\mathrm {Coag}_{α,θ}$. This result may be proved using a subordinator representation and it provides a companion set of relations to those of Pitman between $\operatorname {PD}(α,θ)$ and $\operatorname {PD}(αβ,θ)$. Repeated application of the $\mathrm {Frag}_α$ operators gives rise to a family of fragmentation chains. We show that these Markov chains can be encoded naturally by certain random recursive trees, and use this representation to give an alternative and more concrete proof of the coagulation--fragmentation duality.

description: Unmanned Aerial Vehicle (UAV) networks can provide a resilient communication infrastructure to enhance terrestrial networks in case of traffic spikes or disaster scenarios. However, to be able to do so, they need to be based on high-bandwidth wireless technologies for both radio access and backhaul. With this respect, the millimeter wave (mmWave) spectrum represents an enticing solution, since it provides large chunks of untapped spectrum that can enable ultra-high data-rates for aerial platforms. Aerial mmWave channels, however, experience characteristics that are significantly different from terrestrial deployments in the same frequency bands. As of today, mmWave aerial channels have not been extensively studied and modeled. Specifically, the combination of UAV micro-mobility (because of imprecisions in the control loop, and external factors including wind) and the highly directional mmWave transmissions require ad hoc models to accurately capture the performance of UAV deployments. To fill this gap, we propose an empirical propagation loss model for UAV-to-UAV communications at 60 GHz, based on an extensive aerial measurement campaign conducted with the Facebook Terragraph channel sounders. We compare it with 3GPP channel models and make the measurement dataset publicly available.

description: Over much of the initial mass function, stars are destined to become luminous and cool red giants. They may then be able to produce dust in an atmosphere which has been elevated by strong radial pulsations, and hence drive a wind. The amount of mass that is lost in this way can be a very significant fraction of the stellar mass, and especially in the case of intermediate-mass stars it is highly enriched. The delay between a star's birth and its feedback into the environment varies from several million years for massive stars to almost the age of the Universe for the least massive red giants we see today. I here present a review on the metallicity dependence of red giant winds. I show that recent measurements not only confirm theoretical expectations, but also admonish of common misconceptions with implications for feedback at low initial metallicity.

description: A recent survey indicated that many procedures view risk in a safety-first context. Traditional methods used to impose safety-first constraints in optimization models have often been difficult to implement. This is particularly true when endogenous decisions affect the distribution of the chance-constrained random variable. This paper presents a method whereby probabilistic constraints can be easily imposed upon finitely discrete random variables. The procedure uses a linear version of the lower partial moment stochastic inequality. The resulting solutions are somewhat conservative but are less so than the results using the previously published mean income-absolute deviation stochastic inequality.

description: Defined substoichiometric titanium oxides (Ti$_x$O$_{2x-1}$ with $3 < x < 10$) called Magneli phases have been investigated mostly for their unusual high conductivity and metal-like behavior. In photocatalysis, Magneli phase containing titania particles have been reported to provide favorable charge separation resulting in enhanced reaction efficiency. In the current work we describe a one-step synthesis of Magneli-containing mixed phase nanoparticles that carry directly integrated minute amounts of Pt. Phase optimized nanoparticles that contain only a few hundred ppm Pt are very effective photocatalysts for H$_2$ evolution (they provide a 50-100 times higher H$_2$ evolution than plain anatase loaded with a similar amount of Pt). These photocatalysts are synthesized in a setup combining a hot-wall reactor that is used for TiOx synthesis with a spark generator producing Pt nanoparticles. Different reactor temperatures result in various phase ratios between anatase and Magneli phases. The titania nanoparticles (ca. 24 - 53 nm) were characterized using XRD, HRTEM, XPS and EPR spectra as well as ICP-OES analysis. The best photocatalyst prepared at 900$^\circ$C (which consists of mixed phase particles of 32% anatase, 11% rutile and 57% Magneli phases loaded with 290 ppm of Pt) can provide a photocatalytic H$_2$ evolution rate of ca. 5432 micromol h$^{-1} g$^{-1}$ for UV and ca. 1670 micromol h$^{-1} g$^{-1}$ for AM1.5 illumination. For powders converted to higher amounts of Magneli phases (1000$^\circ$C and 1100$^\circ$C), a drastic loss of the photocatalytic H$_2$ generation activity is observed. Thus, the high photocatalytic efficiency under best conditions is ascribed to an effective synergy between multi-junctions of Magneli titania and Pt that enable a much more effective charge separation and reaction than conventional Pt/anatase junctions.

description: The polarized longitudinal-transverse structure function $σ_{LT^\prime}$ measures the interference between real and imaginary amplitudes in pion electroproduction and can be used to probe the coupling between resonant and non-resonant processes. We report new measurements of $σ_{LT^\prime}$ in the $N(1440){1/2}^+$ (Roper) resonance region at $Q^2=0.40$ and 0.65 GeV$^2$ for both the $π^0 p$ and $π^+ n$ channels. The experiment was performed at Jefferson Lab with the CEBAF Large Acceptance Spectrometer (CLAS) using longitudinally polarized electrons at a beam energy of 1.515 GeV. Complete angular distributions were obtained and are compared to recent phenomenological models. The $σ_{LT^\prime}(π^+ n)$ channel shows a large sensitivity to the Roper resonance multipoles $M_{1-}$ and $S_{1-}$ and provides new constraints on models of resonance formation.

description: Sanitary regulations, product definitions, grades, production or processing regulations, and other qualitative standards are generally applied to both domestic production and imported goods. These quality restrictions can be seen as trade barriers, although it is often difficult to determine whether a given restriction is based on legitimate health or safety concerns or is simply an alternative device for protecting producers. The purpose of this paper is to evaluate the welfare effects of a recent quality regulation, the European Community ban on the use of hormones in livestock production. A conceptual framework is developed to analyze the effects of the ban on the market for edible offals. The results indicate that Community prices for edible offals will increase 34% to 45%, while the world price will fall by at least 35%.
Giant microwave absorption in s- and d- wave superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We discuss a new mechanism of microwave absorption in s- and d-wave superconductors, which arises in the presence of a dc supercurrent in the system. It produces a contribution to the ac conductivity that is proportional to the inelastic quasiparticle relaxation time. This contribution also determines the supercurrent dependence of the conductivity. It may significantly exceed the conventional contribution because in typical superconductors the inelastic relaxation time is several orders of magnitude longer than the elastic one. We show that the aforementioned contribution to the conductivity may be expressed in terms of the single particle density of states in superconductors in the presence of a dc supercurrent. Our results may enable determination of the inelastic relaxation time in superconductors from microwave absorption measurements.

description: Starting from a set of coupled Boltzmann equations, we investigate the thermalization of a two-species cold atomic gas confined either in a box or in an isotropic harmonic trap. We show that the thermalization times, by contrast to the collision rate, depend on the interferences between scattering partial waves. The dynamics of thermalization in a harmonic trap is also strongly dependent upon the ratio between the collision rate and the trap frequencies.

description: We investigate the dynamical interplay between topological state of matter and a non-Markovian dissipation, which gives rise to a new and crucial time scale into the system dynamics due to its quantum memory. We specifically study a one-dimensional polaronic topological superconductor with phonon-dressed $p$-wave pairing, when a fast temperature increase in surrounding phonons induces an open-system dynamics. We show that when the memory depth increases, the Majorana edge dynamics transits from relaxing monotonically to a plateau of substantial value into a collapse-and-buildup behavior, even when the polaron Hamiltonian is close to the topological phase boundary. Above a critical memory depth, the system can approach a new dressed state of topological superconductor in dynamical equilibrium with phonons, with nearly full buildup of Majorana correlation.

description: Suppose $\mathfrak{R}$ is a $2$,$3$-torsion free unital alternative ring having an idempotent element $e_1$ $\left(e_2 = 1-e_1\right)$ which satisfies $x \mathfrak{R} \cdot e_i = \{0\} \rightarrow x = 0$ $\left(i = 1,2\right)$. In this paper, we aim to characterize the commuting maps. Let $φ$ be a commuting map of $\mathfrak{R}$ so it is shown that $φ(x) = zx + Ξ(x)$ for all $x \in \mathfrak{R}$, where $z \in \mathcal{Z}(\mathfrak{R})$ and $Ξ$ is an additive map from $\mathfrak{R}$ into $\mathcal{Z}(\mathfrak{R})$. As a consequence a characterization of anti-commuting maps is obtained and we provide as an application, a characterization of commuting maps on von Neumann algebras relative alternative $C^{*}$-algebra with no central summands of type $I_1$.

description: In this paper, we investigate the dynamics of spherical droplets in the presence of a source-sink pair flow field. The dynamics of the droplets is governed by the Maxey-Riley equation with Basset-Boussinesq history term neglected. We find that, in the absence of gravity, there are two distinct behaviours for the droplets: small droplets cannot go further than a specific distance, which we determine analytically, from the source before getting pulled into the sink. Larger droplets can travel further from the source before getting pulled into the sink by virtue of their larger inertia, and their maximum travelled distance is determined analytically. We investigate the effects of gravity, and we find that there are three distinct droplet behaviours categorised by their relative sizes: small, intermediate-sized, and large. Counterintuitively, we find that the droplets with minimum horizontal range are neither small nor large, but of intermediate size. Furthermore, we show that in conditions of regular human respiration, these intermediate-sized droplets range in size from a few $μ$m to a few hundred $μ$m. The result that such droplets have a very short range could have important implications for the interpretation of existing data on droplet dispersion.

description: Every year microprocessor core is shrinking in size owing to the advancement in technology and decrease in technology node. The new challenges include more stringent and rigorous performance targets compared to previous project. Performance targets include timing, power as well as area optimization. With every new design of microprocessor core there can be a requirement of new techniques to be added to the existing once. The main goal is to improve Timing as well as Power so as to achieve higher quality of design through cell resizing, logic optimization, clock tuning, CTS, dual/quad insertion. Operating frequency and voltage are fixed for each project. Activity Factor is a constant quantity depending on the design. ssThe optimization methods mentioned in this work, focuses on reduction of dynamic capacitance and the resistance to reduce the dynamic power of the circuit. These techniques mentioned in this paper are tested and results analyzed

description: Spectral statistics of hermitian random Toeplitz matrices with independent identically distributed elements is investigated numerically. It is found that the eigenvalue statistics of complex Toeplitz matrices is surprisingly well approximated by the semi-Poisson distribution belonging to intermediate-type statistics observed in certain pseudo-integrable billiards. The origin of intermediate behaviour could be attributed to the fact that Fourier transformed random Toeplitz matrices have the same slow decay outside the main diagonal as critical random matrix ensembles. The statistical properties of the full spectrum of real random Toeplitz matrices with i.i.d. elements are close to the Poisson distribution but each of their constituted sub-spectra is again well described by the semi-Poisson distribution. The findings open new perspective in intermediate statistics.

Role of inducible nitric oxide synthase in the acute activation of murine vascular smooth muscle BK channels by internally applied lipopolysaccharide
Creators: name: Yakubovich, Natalia
Publisher: name: University of British Columbia
Year: 2009

description: The role of inducible nitric oxide synthase (iNOS) in the acute activation of large conductance, Ca²⁺-activated K⁺ channels (BK channels) by the internally applied Escherichia coli lipopolysaccharide (LPS) was studied in murine vascular smooth muscle cells. Primary cell culture, immunocytochemistry, and patch clamp recording techniques were utilized. Immunocytochemical studies showed that rat cerebrovascular arteries fixed promptly upon donor rat sacrifice stained negative for iNOS. However, within 1.5 h of brain removal, iNOS-like immunoreactivity could be detected in cerebrovascular smooth muscle cells (CVSMCs) enzymatically dispersed from rat cerebral arteries, suggesting rapid induction of this protein during cell isolation. Confocal microscopy demonstrated localization of iNOS-like immunoreactivity in the cytoplasm and under the sarcolemma of rat CVSMCs. LPS was then applied to the cytoplasmic face of inside-out membrane patches excised from rat CVSMCs within 2.5-8 h of donor rat sacrifice. It was found that 50 μg/ml LPS rapidly and reversibly increased the open probability of B K channels in these patches, leaving the single channel conductance unaltered. Kinetic analysis showed that LPS activated B K channels by shortening long-duration channel closures, while having little effect on the average duration of channel openings. Importantly, the acute activation of B K channels by LPS was not altered in the presence of the non-isoform specific NOS inhibitor N[sup ω]-nitro-L-arginine (L-NNA, 100 uM). Inside-out patch clamp recordings obtained from wild-type mouse aortic smooth muscle cells (ASMCs) revealed BK channels which had large conductance, were activated by elevation in intracellular calcium and upon membrane depolarization, and were blocked by intracellular tetraethylammonium (25 mM). The effects of LPS on these channels were next compared in wild-type and iNOS knockout (iNOS-KO) mice. Cytoplasmic.application of 50 μg/ml LPS acutely activated B K channels in inside-out patches of ASMC membrane derived from iNOSKO mice, with a degree of potentiation not significantly different from that observed in wildtype mice. These studies establish that internally applied LPS can activate murine vascular smooth muscle B K channels independently of iNOS expression or activity. The mechanism which underlies this novel LPS response remains to be elucidated.

description: In this paper we employ Tolman VII solution with exotic matter that may be present in the extremely dense core of compact objects. The Tolman VII solution, an exact analytic solution to the spherically symmetric, static Einstein field equations with a perfect fluid source, has many characteristics that make it interesting for modeling high density stellar astronomical objects. For our purpose we use generalized non-linear equation of state which may incorporate exotic matter along with dust, radiation and dark energy. The equation of state (EoS) has a linear contribution comprising quark/radiation matters and a nonlinear contribution comprising dark energy/exotic matters. The amount of exotic matter contain can be modify by a parameter $n$ which can be linked to adiabatic index. As $n$ increases the exotic contribution increases which stiffens the EoS. The physical properties of the model such as pressure, density, mass function, surface redshift, gravitational redshift are examined and the stability of the stellar configuration is discussed in details. The model has promising features as it satisfies all energy conditions and is free from central singularities. The $M-R$ relation is constructed analytically and the maximum mass and its corresponding radius is determined using the exact solutions and is shown to satisfy various observational stellar compact stars.

Different methods to determine the bump bonding yield with electrical measurements have been developed. Measurements of several operational parameters are also included in the qualification procedure. Among them are pixel noise, gains and pedestals. Test and qualification procedures of the pixel barrel modules are described and some results are presented.

description: The luminous high-redshift (z=2.17) quasar S50836+710 has been observed in October 1997 with the VSOP at 1.6 GHz and 5 GHz. We report here a previously unpublished image made from the data at 1.6 GHz and compare the structure of a relativistic jet in this quasazr at the two frequencies. We present a spectral index image tracing spectral properties of the jet up to ~40 milliarcsecond distance from the nucleus. The curved jet ridge line observed in the images and the spectral index distribution can be described by Kelvin-Helmholtz instability developing in a relativistic outflow with a Mach number of ~6. In this description, the overall ridge line of the jet is formed by the helical surface mode of Kelvin-Helmholtz instability, while areas of flatter spectral index embedded into the flow correspond to pressure enhancements produced by the elliptical surface mode of the instability. An alternative explanation involving a sequence of slowly dissipating shocks cannot be ruled out at this point.

description: Motivated by D-brane scenarios, we consider a non-supersymmetric model based on the gauge symmetry U(3)_CxU(3)_LxU(3)_R$ which is equivalent to the SU(3)^3 ``trinification'' model supplemented by three U(1)s. Two U(1) combinations are anomalous while the third U(1)_Z' is anomaly free and contributes to the hypercharge generator. This hypercharge embedding correspods to sin^2θ_W=6/19 in the case of full gauge coupling unification. The U(3)^3 symmetry is broken down to the Standard Model by vev's of two (1,3,\bar3)- scalar multiplets supplemented by two Higgs fields in (1,3,1) and (1,1,3) representations. The latter break U(1)_Z' and provide heavy masses to the extra lepton doublets. Fermions belong to (3,\bar 3,1)+(\bar 3,1,3)+ (1,3,\bar 3) representations as in the trinification model. The model predicts a natural quark-lepton hierarchy, since quark masses are obtained from tree-level couplings, while charged leptons receive masses from fourth order Yukawa terms, as a consequence of the extra abelian symmetries. Light Majorana neutrino masses are obtained through a see-saw type mechanism operative at the SU(3)_R breaking scale of the order M_R\ge 10^9 GeV.

description: A new variant of the supersymmetric Fat Higgs model is presented in which the MSSM Higgses as well as the top quark are composite. The underlying theory is an s-confining SU(3) gauge theory with the MSSM gauge groups realized as gauged sub-groups of the chiral flavor symmetries. This motivates the large Yukawas necessary for the large top mass and SM-like Higgs of mass>>M_Z in a natural way as the residual of the strong dynamics responsible for the composites. This removes fine-tuning associated with these couplings present in the original Fat Higgs and New Fat Higgs models, respectively.

description: Die digitalen Möglichkeiten der Partizipation, Informationsbeschaffung und Bildung sind Schlüsselressourcen einer Wissensgesellschaft. Was heißt das für Institutionen, die weltweit im Kulturaustausch tätig sind? Wie kann das Potenzial, das für die Akteure der Auswärtigen Kultur- und Bildungspolitik in der Verbreitung von Online-Medien liegt, in Zukunft noch besser genutzt werden? Welche Trends gibt es im Bereich der digitalen Partizipation? Wo liegen Chancen, neue Zielgruppen zu erschließen und bestehende besser einzubinden? Und welche digitalen Angebote können Kulturmittler machen, um das Engagement und Wissen ihrer Nutzer zu aktivieren?
 Diese Studie zur Digitalisierung in der Auswärtigen Kultur- und Bildungspolitik beschäftigt sich mit innovativen digitalen Kultur- und Vermittlungsangeboten und stellt zahlreiche Best Practice-Beispiele vor. Der Schwerpunkt liegt dabei auf Partizipation und interaktiven Anwendungen. Ausgewertet wurden dazu die Online-Angebote von Akteuren und Mittlerorganisationen Auswärtiger Kultur- und Bildungspolitik sowie von vergleichbaren Institutionen im Ausland. Zudem flossen Erkenntnisse aus Gesprächen mit Online-Konzeptionern und –Redakteuren sowie mit Experten aus den Bereichen Online-Partizipation, Big Data und E-Democracy ein.
 Zehn Handlungsempfehlungen zeigen Wege auf, wie die Mittlerorganisationen ihre Online-Strategien voranbringen und den Bereich der digitalen Partizipation stärken können. Eine Digitalisierungsstrategie sollte die Grundlage schaffen, Institutionen in allen Arbeitsbereichen digital aufzustellen und das Digitale bei Mitarbeitern aller Ebenen zu verankern. Es sollten Möglichkeiten für Pilotprojekte geschaffen werden, Expertise in Datenmanagement und -analyse aufgebaut bzw. erweitert und Kooperationen mit kleineren Firmen, Start-ups, Entwicklern und Kreativen eingegangen werden, um innovative Projekte zu entwickeln.

description: The main aspects of XML retrieval are identified by analysing and comparing the following two behaviours: the behaviour of the assessor when judging the relevance of returned document components; and the behaviour of users when interacting with components of XML documents. We argue that the two INEX relevance dimensions, Exhaustivity and Specificity, are not orthogonal dimensions; indeed, an empirical analysis of each dimension reveals that the grades of the two dimensions are correlated to each other. By analysing the level of agreement between the assessor and the users, we aim at identifying the best units of retrieval. The results of our analysis show that the highest level of agreement is on highly relevant and on non-relevant document components, suggesting that only the end points of the INEX 10-point relevance scale are perceived in the same way by both the assessor and the users. We propose a new definition of relevance for XML retrieval and argue that its corresponding relevance scale would be a better choice for INEX.

description: Resonant tunneling of electrons between two ferromagnets and a quantum dot in the presence of an externally applied magnetic field reveals a strong gate dependence in the linear and nonlinear bias regime. This gate dependence originates from the interplay between Coulomb interactions and spin-dependent hybridization between the quantum dot and the leads. To take into account Coulomb interaction strengths of the same order of magnitude as the external magnetic field and the hybridization strength we adopt the numerically exact iterative summation of path integrals (ISPI).

description: A technique is demonstrated which efficiently transfers light between a tapered standard single-mode optical fiber and a high-Q, ultra-small mode volume, silicon photonic crystal resonant cavity. Cavity mode quality factors of 47000 are measured, and a total fiber-to-cavity coupling efficiency of 44% is demonstrated. Using this efficient cavity input and output channel, the steady-state nonlinear absorption and dispersion of the photonic crystal cavity is studied. Optical bistability is observed for fiber input powers as low as 250 μW, corresponding to a dropped power of 100 μW and 3 fJ of stored cavity energy. A high-density effective free-carrier lifetime for these silicon photonic crystal resonators of 0.5 ns is also estimated from power dependent loss and dispersion measurements.
The Hamilton-Jacobi Equation and Holographic Renormalization Group Flows on Sphere

description: We study the Hamilton-Jacobi formulation of effective mechanical actions associated with holographic renormalization group flows when the field theory is put on the sphere and mass terms are turned on. Although the system is supersymmetric and it is described by a superpotential, Hamilton's characteristic function is not readily given by the superpotential when the boundary of AdS is curved. We propose a method to construct the solution as a series expansion in scalar field degrees of freedom. The coefficients are functions of the warp factor to be determined by a differential equation one obtains when the ansatz is substituted into the Hamilton-Jacobi equation. We also show how the solution can be derived from the BPS equations without having to solve differential equations. The characteristic function readily provides information on holographic counterterms which cancel divergences of the on-shell action near the boundary of AdS.

description: Vehicles have turned into a indispensable part of each one’s life. The well-ordered rising number of transport organizations is making a huge number of issues in traveling. The crisis vehicles like fire engines and ambulance are failing to reach in time makes humankind and financial setbacks too. Circumstances and conditions request the utilization of motor vehicles in the quick-paced city life. Air Pollution is one of the primary effects of the traffic. As a solution, Adaptive timers allowing to a crisis vehicle to achieve the emergency clinic on schedule and the pollution detector are introduced using Li-Fi. The Li-Fi technology gives a completely new layer of remote network within existing wireless networks. The term Li-Fi indicates to visible light communication-(VLC) that utilizes light source as way to deliver high rated speed communication in a manner likely to Wi-Fi. Here, signal will turn green whenever ambulance enters the respective lane. Li-Fi technology utilizes Visible Light Communication (VLC) protocol. The system will update the live information of location on a global server about where the Emergency vehicle is located at that instance. In turn, the driver gets acknowledge from the hospital where the doctor is available. Using the sensor MH-Z19 module Carbon level is also indicated which is emitting from the vehicle. Thus, helps in knowing the air quality in the environment and the vehicle condition as well. The Proposed system makes the ambulance to reach on time. Thus, reduces the waiting time of vehicle in heavy traffic. Li-Fi delivers finer bandwidth, connectivity, efficiency and security more than the Wi-Fi. It has achieved greater speeds larger than ~1 Gbps under the laboratory conditions.

A study of the development of sunjong manhwa by Hwang Mina, Kim Hyerin and Choi In-Sun
Creators: name: Yoon, Yeowon
Publisher: name: University of British Columbia
Year: 2009

description: The main purpose of this thesis is to examine how today's sunjong manhwa (Korean girls' comic) writers are striving to free their works from the influence of shojo manga (Japanese girls' comic) that was predominant in the sunjong manhwa of the last few decades. The concept of the girls' comic is presumed to originate in Japan. To go over this issue specifically I have chosen to talk about the works of three Korean sunjong manhwa writers who are especially popular among today's readers. Before exploring the works of these three writers, the first two chapters address the history of the relationship between Japanese comics and Korean comics in general and the history of relationship between Japanese girls' comics and Korean girls' comics in particular. In Chapter Three, I review the aforementioned three writers and their works. The first writer, Hwang Mina, is like a godmother figure in the sunjong manhwa world who opened up the new possibilities for the sunjong manhwa''?, uniqueness. Hwang Mina had difficulty defining the ethnicity of her manhwa in her earlier works. Nevertheless, going through various stylistic stages in her work has enabled her to mature her idea of manhwa. The second writer, Kim Hyerin's case is slightly different from Hwang Mina's. Kim Hyerin does not believe in the theory of the autogenesis of cultural products. Instead she thinks it is very natural that ideas should be borrowed back and forth, including cross cultures. In fact, she tries to apply her theory of 'absorption-maturity-fermentation' to her works. The fact that the Japanese originated the concept of comics, her works are not Japanese any longer since she has developed it into her own style. The last writer, Choi In-Sun has written only a small number of short manhwa so far. Nevertheless, she plays a very important role in today's sunjong manhwa world as she has come up with very unique and distinctive styled works. Borrowing the theory of absorption-maturity-fermentation, I argue that the works of each writer represent a stage in this process. The progression that has been made from Hwang Mina's early works to the works of Choi In-Sun reflects how today's sunjong manhwa has become a firmly established subculture genre in the Korean manhwa world.
