ON THE ORIGIN OF THE γ-RAY/OPTICAL LAGS IN LUMINOUS BLAZARS

Blazars are strongly variable sources that occasionally show spectacular flares visible in various energy bands. These flares are often, but not always, correlated. In a number of cases, the peaks of optical flares are found to be somewhat delayed with respect to the γ-ray peaks. One notable example of such a delay was found in 3C 279 by Hayashida et al. and interpreted as a result of steeper drop with a distance of the energy density of an external radiation field than of the magnetic energy density. In this paper, we demonstrate that, in general, depending on the respective energy density profile along the jet, such lags can have both signs and that they can take place for any ratio of these energy densities. We study the dependence of such lags on the ratio of these energy densities at a distance of a maximal energy dissipation in a jet, on their gradients, as well as on the time profile of the relativistic electron injection within the moving source. We show how prominent such lags can be, and their expected timescales. We suggest that studies of such lags can provide a powerful tool to resolve the structure of relativistic jets and their radiative environment. As an example we model the lag observed in 3C 279, showing that in this object the flare is produced at a distance of a few parsecs from the central black hole, consistent with our previous inferences based on the spectra and optical polarization properties.
Myocardial Bridge and Coronary Syndrome: Clinical Case Report and Literature Review

Summary The myocardial bridge is a fairly recently reported entity increasingly in young patients, and whose clinic is that of coronary syndrome. Defined as being an intramural segment of a coronary artery `` tunneled segment ‘’ in the myocardium, the Myocar dial Bridge achieves a Milking effect following systole compression of the artery, the most frequently involved in this anomaly is the interventricular earlier. The resulting complications are either mild or even significant. The diagnosis is most often post mortem at autopsy, although coronary angiography reports a few cases like our clinical case. This is a patient in whom the diagnosis was made during coronary angiography, and whose management was pharmacological with good progress.
Variation in Iron Ore Sinter Mineralogy with Changes in Basicity

The target basicity of iron ore sinter is set by blast furnace slag composition requirements, and therefore varies with the proportion of acid burden such as lump iron ore and pellets. Increasing the lump proportion of the burden will increase the target sinter basicity. The mineralogy of sinter produced with a range of basicity between 1.0 and 3.0 was analysed using optical point counting under reflected light microscopy. Sinter from BlueScope Steel’s industrial sinter strand was analysed over a 30-year period, during which time a wide range of iron ore fines blends were utilised and several significant process modifications made. These data were compared with the mineralogy of sinters produced in a pilot-scale sinter pot, a laboratory-scale milli-pot, and small-scale sinter analogues. The mineralogy of the sinters from all scales followed a predictable trend with basicity, generally following the diagram proposed by Bagnall. At a basicity of 1.0, high temperatures were required to produce sinter with adequate strength, resulting in bonding phases dominated by magnetite and glass. Increasing basicity to 2.0 decreased the required sintering temperature and changed the mineralogy to a majority of hematite and SFCA. Further increases in basicity to 3.0 further decreased the required sintering temperature and increased the SFCA and dicalcium silicate content.
The effect of the use of cassava tuber (Manihot esculenta) and Indigofera zollingeriana leaf flour combination as a source of energy supplemented with citric acid in ration on broiler small intestine characteristics and productivity

Objective: The study aimed to determine the effect of using a combination of cassava tuber (Manihot esculenta) and Indigofera zollingeriana leaf flour as an energy source supplemented with citric acid in the ration on performance, carcass quality, digesta pH, viscosity, and the number of villi in the intestines of broilers. Materials and Methods: The research design was completely randomized with five treatments and five replications, each containing four broilers. The treatment was a substitution of corn in the ration with a combination of cassava tuber and I. zollingeriana leaf (CIF): without CIF, 5% CIF substitute for corn + 0.2% citric acid, 10% CIF substitute for corn + 0.2% citric acid, 15% CIF corn substitute + 0.2% citric acid, and CIF corn substitute + 0.2% citric acid. Each treatment ration was supplemented with 0.2% citric acid. The variables that were looked at were ration consumption, body weight gain, feed conversion, live weight, percentage of the carcass, percentage of abdominal fat, pH, viscosity, and the number of broiler villi. Results: This study showed that the combination of CIF flour supplemented with 0.2% citric acid had a significant effect (p < 0.05) on body weight gain, ration conversion, live weight, carcass percentage, and the number of villi in broiler intestines. But it did not have a significant effect (p > 0.05) on the amount of feed eaten, the amount of fat in the abdomen, the pH of the digesta, or the thickness of the broilers’ blood. Conclusions: The combination of CIF flour at a level of 10% supplemented with 0.2% citric acid can be used as an energy source to replace corn without having a bad effect on production performance, carcass quality, and small intestine characteristics of broilers.
A Study on the Influencing Factors of Theme Park Accessibility on Revisit

The purpose of this study was to verify how the level of service perceived by theme park visitors affects satisfaction and revisit. Although the number of theme park visitors has been decreasing since the recent COVID-19 pandemic, it can be seen as a positive influence that the theme park can be a new opportunity to be reborn through a new attempt in which ICT technologies such as VR combined with the 4th industrial revolution technology is combined. Researcher tried to exploratory verification of what is the important factor in the service operation of the theme park. Researcher considered that accessibility perceived by visitors, diversity of services, and symbolic meaning of theme parks could be exogenous variables. And it tried to apply the perceived usefulness and perceived pleasure applied in the TAM study as mediating variables. It is expected that visitors will be satisfied and revisit through recognition of the place and service of this theme park. As a result of the study, it was confirmed that the locational accessibility of the customers visiting the theme park affects the diversity and symbolic meaning of the service. In addition, it was confirmed that the customer affected satisfaction and revisit by using perceived pleasure and perceived usefulness as mediating variables. Therefore, it was confirmed that the theme park operator should provide information such as location and parking, and geographical access services, and focus on perceived joyfulness. After the pandemic, theme parks are expected to focus on theme selection and enjoyment. Researcher considered this research to have theoretical and practical contributions. Lastly, researcher hope that the results of this study will be helpful to the theme park industry in the future.

Lichen Extracts from Cetrarioid Clade Provide Neuroprotection against Hydrogen Peroxide-Induced Oxidative Stress

Oxidative stress is involved in the pathophysiology of many neurodegenerative diseases. Lichens have antioxidant properties attributed to their own secondary metabolites with phenol groups. Very few studies delve into the protective capacity of lichens based on their antioxidant properties and their action mechanism. The present study evaluates the neuroprotective role of Dactylina arctica, Nephromopsis stracheyi, Tuckermannopsis americana and Vulpicida pinastri methanol extracts in a hydrogen peroxide (H2O2) oxidative stress model in neuroblastoma cell line “SH-SY5Y cells”. Cells were pretreated with different concentrations of lichen extracts (24 h) before H2O2 (250 µM, 1 h). Our results showed that D. arctica (10 µg/mL), N. stracheyi (25 µg/mL), T. americana (50 µg/mL) and V. pinastri (5 µg/mL) prevented cell death and morphological changes. Moreover, these lichens significantly inhibited reactive oxygen species (ROS) production and lipid peroxidation and increased superoxide dismutase (SOD) and catalase (CAT) activities and glutathione (GSH) levels. Furthermore, they attenuated mitochondrial membrane potential decline and calcium homeostasis disruption. Finally, high-performance liquid chromatography (HPLC) analysis revealed that the secondary metabolites were gyrophoric acid and lecanoric acid in D. artica, usnic acid, pinastric acid and vulpinic acid in V. pinastri, and alectoronic acid in T. americana. In conclusion, D. arctica and V. pinastri are the most promising lichens to prevent and to treat oxidative stress-related neurodegenerative diseases.
EXTRINSIC AND INTRINSIC VARIABLES AS PREDICTORS OF THE PRESENCE OF TYPES OF ORGANISATIONAL CULTURE: IMPLICATIONS FOR ORGANIZATIONAL DEVELOPMENT

In this research, we analyze the capacity of eight extrinsic and thirteen intrinsic variables to predict the presence of Clan, Market and Hierarchy cultures (Cameron & Quinn, 1999), on one subsample of Spanish managers ( n 1 = 362) and another of Peruvian managers ( n 2 = 1,317). We found, contrary to what most of the literature suggest, that the extrinsic variables show very little predictive capacity. On the other hand, intrinsic variables do have a significant predictive capacity, specific for each culture. Unexpectedly, the results for the Market culture are very different in the two subsamples, suggesting that this archetype have a high variability in its internal configuration. We discuss the implications of these findings.
TRENDS IN 44Ti AND 56Ni FROM CORE-COLLAPSE SUPERNOVAE

We compare the yields of 44Ti and 56Ni produced from post-processing the thermodynamic trajectories from three different core-collapse models—a Cassiopeia A progenitor, a double shock hypernova progenitor, and a rotating two-dimensional explosion—with the yields from exponential and power-law trajectories. The peak temperatures and densities achieved in these core-collapse models span several of the distinct nucleosynthesis regions we identify, resulting in different trends in the 44Ti and 56Ni yields for different mass elements. The 44Ti and 56Ni mass fraction profiles from the exponential and power-law profiles generally explain the tendencies of the post-processed yields, depending on which regions are traversed by the model. We find that integrated yields of 44Ti and 56Ni from the exponential and power-law trajectories are generally within a factor two or less of the post-process yields. We also analyze the influence of specific nuclear reactions on the 44Ti and 56Ni abundance evolution. Reactions that affect all yields globally are the 3α, p(e−, νe)n and . The rest of the reactions are ranked according to their degree of impact on the synthesis of 44Ti. The primary ones include 44Ti(α, p)47V, 40Ca(α, γ)44Ti, 45V(p, γ)46Cr, 40Ca(α, p)43Sc, 17F(α, p)20Ne, 21Na(α, p)24Mg, 41Sc(p, γ)42Ti, 43Sc(p, γ)44Ti, 44Ti(p, γ)45V, and 57Ni(p, γ)58Cu, along with numerous weak reactions. Our analysis suggests that not all 44Ti need to be produced in an α-rich freeze-out in core-collapse events, and that reaction rate equilibria in combination with timescale effects for the expansion profile may account for the paucity of 44Ti observed in supernova remnants.
Angiotensin II Type 2 Receptor Potentiates Skeletal Muscle Satellite Cell Differentiation via the GSK3β/β-catenin Pathway AT2R regulates GSK3β signaling in satellite cells

Patients with advanced congestive heart failure (CHF) or chronic kidney disease (CKD) often have increased systemic angiotensin II (Ang II) levels and cachexia. We previously demonstrated that Ang II infusion in rodents results in skeletal muscle wasting and reduced muscle regenerative potential via Ang II type 1 receptor (AT1R) signaling, potentially contributing to cachexia in CHF and CKD. Contrary to AT1R signaling, we found that signaling via Ang II type 2 receptor (AT2R) potentiates skeletal muscle satellite cell (SC) differentiation and muscle regenerative potential. However, mechanisms whereby AT2R regulates SC differentiation and cachexia development remain unknown. In this study, we found that GSK3β activity was significantly suppressed during SC differentiation, whereas it was retained in SCs with AT2R knockdown. AT2R knockdown leads to higher GSK3β and decreased β-catenin activities both in vitro and in vivo . Treatment with GSK3β inhibitor BIO restored β-catenin activity and differentiation capacity of SCs with AT2R knockdown. Conversely, transgenic overexpression of AT2R in SCs inhibited GSK3β, associated with increased β-catenin activity and SC myogenic capacity both in vitro and in vivo . Interestingly, AT2R expression in undifferentiated SCs was regulated post-transcriptionally. An increase in systemic Ang II blunted AT2R induction during muscle regeneration. However, overexpression of AT2R restored AT2R levels and myogenesis in vivo . Together, these data suggest that the AT2R/GSK3β/β-catenin signaling pathway could serve as a potential therapeutic target to promote muscle regenerative capacity in chronic disease conditions characterized by heightened activation of the renin-angiotensin system, such as CHF and CKD. SCs, and SC differentiation creates an environment in which AT2R protein can be expressed to potentiate SC differentiation. Although it is unknown how AT2R protein levels were suppressed in non-differentiating SCs, these data strongly suggest a mechanism by which AT2R protein levels are strictly controlled in SCs to block precocious activation of SC differentiation.
End-to-end Character-Level Dialogue Breakdown Detection with External Memory Models

Real human-machine dialogues can inevitably end up with breakdown because no rule covers all situations. In particular, performance of the dialogue breakdown detection task for open domain conversation encounters the following technical difﬁ-culties: 1) dialogue histories often contain words which don’t appear directly in training data, and 2) preparing and annotating a large amount of conversation data require human resources. Here, we propose end-to-end memory-network-based detection models having character-level sentence embedding to handle unseen words and an external memory mechanism to integrate information in the local dialogue context. Moreover, to tackle issues of rareness of annotated data, we employ an unsupervised method that is a task to predict the next sentence in an unan-notated document. The results of experiments with a Japanese-language data set indicate that integrating local-context memory information contributes to accuracy improvement.
Nongeometric F-theory–heterotic duality

In this work we study the duality between F-theory and the heterotic string beyond the stable degeneration limit in F-theory and large fiber limit in the heterotic theory. Building upon a recent proposal by Clingher-Doran and Malmendier-Morrison, which phrases the duality on the heterotic side for a particular class of models in terms of (fibered) genus two curves as non-geometric heterotic compactifications - we establish the precise limit to the semi-classical heterotic string in both eight and lower space-time dimensions. In particular for six dimensional theories, we argue that this class of non-geometric heterotic compactifications capture alpha'-quantum corrections to the semi-classical heterotic supergravity compactifications on elliptically fibered K3 surfaces. From the non-geometric heterotic theory, the semi-classical phase on the K3 surface is recovered from a remarkable limit of genus two Siegel modular forms combined with a geometric surgery operation. Finally, in four dimensions we analyze another limit deep in the quantum regime of the non-geometric heterotic string, which we refer to as the heterotic Sen limit. In this limit we can explicitly argue that the semi-classical two-staged fibrational structure of the heterotic hypermultiplet moduli space - recently established by Alexandrov, Louis, Pioline and Valandro - gets corrected by quantum effects.
Black holes in active galactic nuclei

Abstract Supermassive black holes are common in centers of galaxies. Among the active galaxies, quasars are the most extreme, and their black hole masses range as high as to 6⋅1010M⊙. Binary black holes are of special interest but so far OJ287 is the only confirmed case with known orbital elements. In OJ287, the binary nature is confirmed by periodic radiation pulses. The period is twelve years with two pulses per period. The last four pulses have been correctly predicted with the accuracy of few weeks, the latest in 2007 with the accuracy of one day. This accuracy is high enough that one may test the higher order terms in the Post Newtonian approximation to General Relativity. The precession rate per period is 39°. 1 ± 0°. 1, by far the largest rate in any known binary, and the (1.83 ± 0.01)⋅1010M⊙ primary is among the dozen biggest black holes known. We will discuss the various Post Newtonian terms and their effect on the orbit solution. The over 100 year data base of optical variations in OJ287 puts limits on these terms and thus tests the ability of Einstein's General Relativity to describe, for the first time, dynamic binary black hole spacetime in the strong field regime. The quadrupole-moment contributions to the equations of motion allows us to constrain the ‘no-hair’ parameter to be 1.0 ± 0.3 which supports the black hole no-hair theorem within the achievable precision.

Objective: Genetic myopathies are diseases that progress and impair quality of life. In our study, it was aimed to evaluate the relationship between sociodemographic characteristics and quality of life of 146 patients who applied to our unit. Methods: For the quality of life of these patients, the WHOQOL-BREF scale was applied and the scores in the Questionnaire were converted to WHOQOL 4-20 and WHOQOL 0-100 score ranges, and the relationships between the WHOQOL-BREF questionnaire results were evaluated. Results: There was no significant difference in the results of the scale according to gender and age (p>0.05 for all). There were significant findings in terms of education level, marital status, and disease severity in the WHOQOL-BREF scale. Conclusıon: As a result of the study, it is thought that it can be a reference for researchers by revealing the findings that will increase the quality of life of the patients.
A CATALOG OF ULTRA-COMPACT HIGH VELOCITY CLOUDS FROM THE ALFALFA SURVEY: LOCAL GROUP GALAXY CANDIDATES?

We present a catalog of 59 ultra-compact high velocity clouds (UCHVCs) extracted from the 40% complete ALFALFA HI-line survey. The ALFALFA UCHVCs have median flux densities of 1.34 Jy km s−1, median angular diameters of 10′, and median velocity widths of 23 km s−1. We show that the full UCHVC population cannot easily be associated with known populations of high velocity clouds. Of the 59 clouds presented here, only 11 are also present in the compact cloud catalog extracted from the commensal GALFA-HI survey, demonstrating the utility of this separate dataset and analysis. Based on their sky distribution and observed properties, we infer that the ALFALFA UCHVCs are consistent with the hypothesis that they may be very low mass galaxies within the Local Volume. In that case, most of their baryons would be in the form of gas, and because of their low stellar content, they remain unidentified by extant optical surveys. At distances of ∼1 Mpc, the UCHVCs have neutral hydrogen (H i) masses of ∼105–106 M☉, H i diameters of ∼2–3 kpc, and indicative dynamical masses within the H i extent of ∼107–108 M☉, similar to the Local Group ultra-faint dwarf Leo T. The recent ALFALFA discovery of the star-forming, metal-poor, low mass galaxy Leo P demonstrates that this hypothesis is true in at least one case. In the case of the individual UCHVCs presented here, confirmation of their extragalactic nature will require further work, such as the identification of an optical counterpart to constrain their distance.
Research Statement: Context-Aware Sequence Model

My research focuses on developing a context-aware sequence model. Context modeling helps understand the abstract meaning of data, such as sentence or user behavior. Contextual information captures the important underlying feature, and it helps the model to capture the relationship between data instances or hidden representations. The importance of context modeling becomes larger when we deal with sequential data which has its own order. This is because even the same word might have a com-pletely diﬀerent meaning depending on the position and order of words. For the sequential data, we need to consider the context change over time and the relationship between sequential input. Furthermore, we extend our research to handle the multi-granularity and hierarchical context of sequential modeling to deal with long and complex sequences by capturing rich contextual representations. My research focuses on three keywords, sequence, context, and hierarchy on diverse datasets and tasks. Figure 1 visualize my primary research works and experiments that I conducted.
