description: Σκοπός της έρευνας ήταν η μελέτη της σημαντικής συνεισφοράς της προσωπικότητας και της δραστηριοποίησης του Αρχιεπισκόπου Αθηνών και πάσης Ελλάδος Χριστόδουλου σε ζητήματα που αφορούν στην ελληνική παιδεία. Στη συνέχεια παρουσιάσαμε το ρόλο της Ορθόδοξης Χριστιανικής Εκκλησίας στη διάσωση και τον εμπλουτισμό του μεγαλείου της ελληνικής παιδείας, καθώς και στη διαμόρφωση εκείνου του ήθους που καλλιεργεί τη διάκριση ανάμεσα στην πραγματική αξία της παιδείας και της πραγματιστικής αντίληψης για την εκπαίδευση. Ακόμη εξετάσαμε πώς ο τρόπος ζωής της Εκκλησίας συνιστά μια γνήσια κοινωνία ανθρώπων, όπου ο καθένας αποκτά ανθρωπιά και μια ουσιαστική σχέση με τους συνανθρώπους του και τον εαυτό του. Επιπλέον ασχοληθήκαμε με την Εκκλησιαστική Εκπαίδευση, η οποία αποτελεί σημαντικό κεφάλαιο στον στοχασμό του Αρχιεπισκόπου Χριστόδουλου, και για την κατάσταση στην οποία έχει περιέλθει αυτή, λόγω απουσίας διαλόγου μεταξύ Εκκλησίας και Πολιτείας. Η έρευνά μας ολοκληρώθηκε με τις προτάσεις του μακαριστού Αρχιεπισκόπου για την αναβάθμιση της παιδείας, που συνοψίζονται στην ύπαρξη ενός γνήσιου και ειλικρινούς διαλόγου, ο οποίος θα βοηθήσει στην εξυγίανση των θεσμών.
description: The purpose of the research was to study the significant contribution of the personality and the activity of the Archbishop of Athens and all of Greece, Christodoulos in issues concerning Greek education. Then, we presented the role of the Orthodox Christian Church in saving and enriching the greatness of Greek education, as well as in shaping that morals which cultivates the distinction between the true value of education and the pragmatic perception of education. We also examined how the way of life of the Church constitutes a genuine society of people, where everyone acquires humanity and a substantial relationship with his fellow human beings and himself. In addition, we dealt with the Ecclesiastical Education, which constitutes an important asset in the meditation of Archbishop Christodoulos, and the situation in which it has found itself, due to the absence of dialogue between the Church and the State. Our research was completed with the proposals of the Blessed Archbishop concerning the upgrade of education, which are summarized in the existence of a genuine and honest dialogue, which will help in the consolidation of the institutions.

description: Nuclear uncertainties in the production of $p$ nuclei in massive stars have been quantified in a Monte Carlo procedure. Bespoke temperature-dependent uncertainties were assigned to different types of reactions involving nuclei from Fe to Bi. Their simultaneous impact was studied in postprocessing explosive trajectories for three different stellar models. It was found that the grid of mass zones in the model of a 25 $M_\odot$ star, which is widely used for investigations of $p$ nucleosynthesis, is too crude to properly resolve the detailed temperature changes required for describing the production of $p$ nuclei. Using models with finer grids for 15 $M_\odot$ and 25 $M_\odot$ stars with initial solar metallicity, it was found that most of the production uncertainties introduced by nuclear reaction uncertainties are smaller than a factor of two. Since a large number of rates were varied at the same time in the Monte Carlo procedure, possible cancellation effects of several uncertainties could be taken into account. Key rates were identified for each $p$ nucleus, which provide the dominant contribution to the production uncertainty. These key rates were found by examining correlations between rate variations and resulting abundance changes. This method is superior to studying flow patterns, especially when the flows are complex, and to individual, sequential variation of a few rates.

description: Scrambling of quantum information can be conveniently quantified by so called out-of-time-order-correlators (OTOCs), whose measurements presents a formidable experimental challenge. Here we report on a method for the measurement of OTOCs based on the so-called two-point measurements scheme developed in the field of non-equilibrium quantum thermodynamics. The scheme is of broader applicability than methods employed in current experiments and also provides a clear-cut interpretation of quantum information scrambling in terms of non-equilibrium fluctuations of thermodynamic quantities such as work. Furthermore, we provide a numerical example on a spin chain which highlights the utility of our thermodynamic approach when understanding the differences between integrable and ergodic behavior. We also discuss connections to some recent experiments.

Creators: name: Bisrat, Filimona
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1992

description: In Ethiopia, there is no reliable information about sexual behaviours and contraception usage of adolescent students. The incidence of morbidity and mortality of young female students due to induced abortion of unwanted pregnancy is increasing. This is a cross sectional study which was conducted to assess the knowledge, attitude, and practice of high school students in Harar town toward family planning. A total of 1674 students from 11th and 12th grades aged between 15 and 26 years were interviewed by means of self administered anonymous questionnaires. The respondents were 887(52.9%) males and 787 (47.1%) females. The major finding of the study were that 20% of females and 65% of the males admitted to having had sexual intercourse. The average score of knowledge and attitude items about FP was 8.3 out of 13 and 7.3 points out of 10 respectively. Among those who had sexual intercourse, 60.3% of the females and 67.1% of the males reported that they knew at least one type of contraceptive methods. Of the sexually active females, 59.6% were using one of the contraceptive methods. However, the majority (76.3%) were using the calender method and only 19.4% said they used birth control pills or condoms. One fifth of the male respondents (20.0%) used condoms. A total of 21.8% of females who are sexually experienced have been pregnant, and 55.9% of them have terminated the pregnancy by means of induced abortion. vii The main source of eM information was mass media (31. 3 %) followed by school (24.2%). More than half of the respondents (53.3%) have an intention to use contraceptive methods in the future . The majority (93.7%) of the respondents approved the provision of information in school about contraception and STDs. In our findings the knowledge of the students was modest and the practice of contraceptive utilization was low. This information can be used in planning family life education programs. viii

description: We show that a model with a scalar leptoquark of hypercharge $Y=1/6$ which includes the light right-handed neutrinos, can successfully describe both of the $B$-physics anomalies, $R_K^{\rm exp} < R_K^{\rm SM}$ and $R_D^{\rm exp} > R_D^{\rm SM}$. We discuss the corresponding low energy effective theory and, after using the known experimental data as constraints, we show that the model is viable and that it offers several predictions which can be tested experimentally.

description: Um an aktuelle Entwicklungen angepasst zu bleiben, unterliegen Schulbücher einem ständigen Wandel. Neben den mathematischen Inhalten, die durch Lehr- und Bildungspläne reguliert werden, zeigen sich solche Veränderungen auch in außermathematischen Aspekten. Dazu zählen beispielsweise die in den Schulbüchern auftretenden Sachkontexte. Auch innerhalbder didaktischen Umsetzung der mathematischen Inhalte ergeben sich Unterschiede. Diese werden zum einen in Aufbau und Gestaltung der Lehrgänge deutlich, spiegeln sich aber auch in einzelnen didaktischen Ideen, wie zum Beispiel der Offenheit von Aufgaben, wieder.

description: Nitrile imine derivative 3 added regioselectively to α-(benzothiazol-2-yl)cinnamonitrile derivatives 1a–c to afford 5-(benzothiazol-2-yl)-5-cyano-4,5-dihydro-1H-pyrazole derivatives 4a–c. Compound 4a underwent thermal elimination of hydrogen cyanide in sodium ethoxide solution to give the pyrazole derivative 6. The isoxazole derivative 10 was synthesized by reacting nitrile oxide 8 with cinnamonitrile derivative 1d. The structures of the synthesized compounds were characterized by FT-IR, NMR, and MS spectroscopic techniques. The reaction mechanism was studied via density functional theory (DFT) quantum chemical calculations at the B3LYP/6-31G (d) level of theory.

description: Magnetic pulse welding is a rapid process (takes place within few micro seconds) that joins both homogeneous and heterogeneous materials in the solid state. The process involves applying variable high current on an inductor to generate Lorentz forces on to the conductive primary part (flyer). To realize the weld it is necessary to accelerate the flyer to impact on to the secondary stationary part (base material) at a very high velocity attained over the distance, called air gap, between the parts. It is typically possible to perform welding of tubes and sheets provided there is an optimized air gap between the parts to be welded. As part of our work we have developed an innovative approach (Magnetic Pulse Spot Welding-MPSW) that eliminates the delicate task of maintaining the aforementioned air gap between the plates. The proposed method opens better viable perspectives for heterogeneous assembly of automotive structures or connecting batteries in a quasi-cold state. The developed approach has been validated on the heterogeneous assembly Al/Fe by tensile tests (quasi-static and dynamic) that attested the quality of welds.

Organizational Responses and Sexual and Reproductive Health Needs of Street Children in Addis Ababa
Creators: name: Demelash, Habtamu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Background - The lives of millions of street children worldwide are at risk because they do not have the information, skills, health services and support they need to go through sexual development during adolescence. It was time to put in place viable programmes or strategies that will ensure the sexual health problems street children are urgently addressed. But rigorous assessment has not been undertaken so far to identify whether special and street children-friendly sexual and reproductive health and HIV/ AIDS prevention and treatment services were existing in Addis Ababa. This study is therefore undertaken to systematically investigate the fit between street children's sexual and reproductive health needs and the existing programmatic responses. Objective - This paper tried to explore to what extent the present health interventions address sexual and reproductive health needs of street children in Addis Ababa. Method-Across-sectional study was conducted among 422 street children and four service providers using a structured questionnaire, focus group discussions and through individual interview. Study participants were selected using time location sampling (TLS) technique which includes different areas at different time in five sub cities of Addis Ababa. Results -At the time of the survey, most participants (72.5%) were ever had sexual intercourse (66.2% of boys, and 90.4% of girls) and the mean age at their first sexual intercourse were 15.4 years for males and 14.3 years for females. Comparing males and females, 84.3% of males and 85.7% of females tended to have multiple sexual partners. Concerned to Substance use, more than two third (67.3%) of the participants were used at least one type of substance. A history of drug use (OR = 2.5; 95% CI = 1.42–4.56), and being on the street for the first 1-3 years (OR = 5.9; 95% CI=1.41- 25.22) increased the likelihood of displaying sexual activity. A large proportion (64.9%) of the street children did not attend any kind of sexual and reproductive health education programs. Regarding Perceived and actual barriers, limited access to local sexual and reproductive health services, 26.5% of participants stated lack of information on available services as the biggest barrier. From the individual interview with coordinator of special clinics for street children, it was indicated that financial and networking problems were affecting the service delivery for children by different actors. Conclusion- Street children who are special high risk group, have not been targeted and hence continue to remain vulnerable and lacking in sexual and reproductive health services that cater to their needs and sexual health services are poorly advertised and delivered to them

The scheme allows for the natural implementation of a type II seesaw mechanism for Dirac neutrinos, while charged lepton and quark masses are reproduced in a natural way thanks to the presence of new scalars. The new $\mathrm{SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$ energy scale characterizing neutrino mass generation could be accessible to the current LHC experiments.

description: One of the best ways to design new biocidal agents is synthesizing hybrid molecules. So, new series of antipyrine-bearing thiazole moiety were synthesized using 4-antipyrinecarboxaldehyde thiosemicarbazones 1a–e. Cyclization of thiosemicarbazone derivatives 1a–e with ethyl 2-chloroacetate, ethyl 2-chloropropanoate, 1-chloropropan-2-one (chloroacetone) and 2-bromo-1-phenylethanone (phenacyl bromide) afforded the corresponding thiazolidin-4-ones 2a–e, 5-methyl-thiazolidin-4-ones 3a–e, 4-methylthiazoles 4a–e and 4-phenylthiazoles 5a–e, respectively. The antibacterial and antifungal activates for the synthesized compounds were investigated.

description: A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV at the LHC is presented. The cross-sections are obtained using top-quark pair decays with an opposite-charge electron-muon pair in the final state and with data corresponding to an integrated luminosity of about 5 fb$^{-1}$ at $\sqrt{s}=7$ TeV and about 20 fb$^{-1}$ at $\sqrt{s}=8$ TeV for each experiment. The combined cross-sections are determined to be $178.5 \pm 4.7$ pb at $\sqrt{s}=7$ TeV and $243.3^{+6.0}_{-5.9}$ pb at $\sqrt{s}=8$ TeV with a correlation of 0.41, using a reference top-quark mass value of 172.5 GeV. The ratio of the combined cross-sections is determined to be $R_{8/7}= 1.363\pm 0.032$. The combined measured cross-sections and their ratio agree well with theory calculations using several parton distribution function (PDF) sets. The values of the top-quark pole mass (with the strong coupling fixed at 0.118) and the strong coupling (with the top-quark pole mass fixed at 172.5 GeV) are extracted from the combined results by fitting a next-to-next-to-leading-order plus next-to-next-to-leading-log QCD prediction to the measurements. Using a version of the NNPDF3.1 PDF set containing no top-quark measurements, the results obtained are $m_t^\text{pole} = 173.4^{+1.8}_{-2.0}$ GeV and $\alpha_\text{s}(m_Z)= 0.1170^{+ 0.0021}_{-0.0018}$.

description: Background: -Treatment of HIV infected patients with Highly Active Antiretroviral Therapy (HAART) leads to immune reconstitution as shown by increase in CD4+ lymphocyte counts, decreased risk of opportunistic infection and improve survival, however, little is known about its impact on hematological parameters in resource limited settings like Ethiopia. Objective: -To assess hematological profile among adult HIV infected individuals at the baseline and six month after initiation of Highly Active Antiretroviral Therapy. Methods: -Retrospective cohort study was conducted among HIV infected adult patients who attended ART clinic and received HAART between September 2005 and August 2010 at ART clinic of Black Lion Specialized Hospital Addis Ababa, Ethiopia. A total of 379 subjects were selected based on convenience sampling. Demographic, clinical and hematological (WBC, CD4+ T cells, Hgb and Platelets) data were collected between July and August 2010 carefully from the existing ART logbook and patient follow up cards accordingly.Selected hematological abnormalities were defined as leucopenia, thrombocytopenia, severe thrombocytopenia, anemia and immunodeficiency. Data collected through a standardized questionnaire were entered into Excel spread sheet and transported into and analyzed by SPSS Version 15.0 soft ware (SPSS INC, Chicago, IL, USA).Median change of different hematological values during follow up time between consecutive visits and each follow up from the base line were compared using Wilcoxon signed rank test. Results: -At the baseline 379 subjects who started ART from September 2005 to August 2010 were included in the study; 240 of the patients were females. The subjects studied had a baseline CD4+ T cells count ranging from 4-573 cells/ul, median 111 cells/uL IQR (72-176). 329 (86.8%) of the study subjects were having CD4 + T cell count below 200 cells/ul and CD4+ T cell count of<50 cells/ul was seen in 69(18.2%) patients. Moreover, 25 (9.5 %) of the patients were leucopenic, 104 (43.3 %) of females and 60(43.2%) of males were anemic while 60(15.8 %) of the total 379 patients were thrombocytopenic. After six month initiation of HAART, the median CD4+ T cell count was 190 cells/uL IQR (128-278), thrombocytopenia was seen only in 25(6.6%) of the patients and 25 (6.6 %) were leucopenic. The prevalence of anemia was only 22.7 % and 18.8 % in females and males respectively. Conclusion: -HAART improved CD4+T cell count, Hgb, white blood cells and platelet count of HIV infected individuals. The difference in hematological parameters between baseline and after 6 month initiation of HAART was statistically significant (P< 0.05).

description: Observations reveal a uniform Kolmogorov turbulence throughout the diffuse ionized interstellar medium (ISM) and supersonic turbulence preferentially located in the Galactic plane. Correspondingly, we consider the Galactic distribution of electron density fluctuations consisting of not only a Kolmogorov density spectrum but also a short-wave-dominated density spectrum with the density structure formed at small scales due to shocks. The resulting dependence of the scatter broadening time on the dispersion measure (DM) naturally interprets the existing observational data for both low and high-DM pulsars. According to the criteria that we derive for a quantitative determination of scattering regimes over wide ranges of DMs and frequencies $ν$, we find that the pulsars with low DMs are primarily scattered by the Kolmogorov turbulence, while those at low Galactic latitudes with high DMs undergo more enhanced scattering dominated by the supersonic turbulence, where the corresponding density spectrum has a spectral index $\approx 2.6$. Besides, by considering a volume filling factor of the density structures with the dependence on $ν$ as $\propto ν^{1.4}$ in the supersonic turbulence, our model can also explain the observed shallower $ν$ scaling of the scattering time than the Kolmogorov scaling for the pulsars with relatively large DMs. The comparison between our analytical results and the scattering measurements of pulsars in turn makes a useful probe of the properties of the large-scale ISM turbulence, e.g., an injection scale of $\sim 100$ pc, and also characteristics of small-scale density structures.

description: The first observation of the production of W$^\pm$W$^\pm$ bosons from double parton scattering processes using same-sign electron-muon and dimuon events in proton-proton collisions is reported. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ recorded at a center-of-mass energy of 13 TeV using the CMS detector at the CERN LHC. Multivariate discriminants are used to distinguish the signal process from the main backgrounds. A binned maximum likelihood fit is performed to extract the signal cross section. The measured cross section for production of same-sign W bosons decaying leptonically is 80.7 $\pm$ 11.2 (stat) $^{+9.5}_{-8.6}$ (syst) $\pm$ 12.1 (model) fb, whereas the measured fiducial cross section is 6.28 $\pm$ 0.81 (stat) $\pm$ 0.69 (syst) $\pm$ 0.37 (model) fb. The observed significance of the signal is 6.2 standard deviations above the background-only hypothesis.

description: A search for the standard model Higgs boson decaying to a charm quark-antiquark pair, H $\to \mathrm{c\bar{c}}$, produced in association with a leptonically decaying V (W or Z) boson is presented. The search is performed with proton-proton collisions at $\sqrt{s}$ = 13 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 138 fb$^{-1}$. Novel charm jet identification and analysis methods using machine learning techniques are employed. The analysis is validated by searching for Z $\to \mathrm{c\bar{c}}$ in VZ events, leading to its first observation at a hadron collider with a significance of 5.7 standard deviations. The observed (expected) upper limit on $\sigma$(VH)$\mathcal{B}$(H$\to \mathrm{c\bar{c}}$) is 0.94 (0.50$^{+0.22}_{-0.15}$) pb at 95% confidence level (CL), corresponding to 14 (7.6$^{+3.4}_{-2.3}$) times the standard model prediction. For the Higgs-charm Yukawa coupling modifier, $\kappa_\mathrm{c}$, the observed (expected) 95% CL interval is 1.1 $\lt\vert\kappa_\mathrm{C}\vert \lt$ 5.5 ($\vert\kappa_\mathrm{c}\vert\lt$ 3.4), the most stringent constraint to date.

description: The linear waves that propagate in a two fluid magnetised plasma allowing for a non-gyrotropic perturbed ion pressure tensor are investigated. For perpendicular propagation and perturbed fluid velocity a low frequency (magnetosonic) and a high frequency (ion Bernstein) branch are identified and discussed. For both branches a comparison is made with the results of a truncated Vlasov treatment. For the low frequency branch we show that a consistent expansion procedure allows us to recover the correct expression of the Finite Larmor Radius corrections to the magnetosonic dispersion relation.

description: One of the key issues of emerging mobile computing and robotics is to obtain knowledge of the position of persons, vehicles and objects in an indoor environment. In order to enable a pervasive coverage, this must be achieved at low cost. Due to the importance of this problem, numerous solutions have been proposed. In this thesis two important localization techniques are discussed and major improvements are developed to address their weaknesses. A common approach for the position estimation problem is hyperbolic localization. This method is based on time difference of arrival (TDOA) measurements of signals transmitted from the mobile unit, i.e. the unit that is to be located, to a set of fixed reference units. A key requirement of this technique is that the clocks of the reference devices are synchronized. Unfortunately, if electromagnetic signals are used that travel at the speed of light even a very small clock deviation results in a tremendous inaccuracy of the computed location. Therefore, a highly precise time measurement and synchronization is mandatory for these systems. However, clocks operating at the required resolution and precision are complex and thus expensive. In this thesis, a localization approach based on TDOA measurements that implies clock synchronization is proposed and discussed. It allows for the usage of low cost oscillators that operate at a moderate frequency in the order of 100 MHz. The impact of short and long term instabilities like jitter or clock drift are inherently delimited. The approach can be applied to radio or infrared as well as ultrasound based systems. The main advantage of this approach is that common synchronization mechanisms that require a significant amount of processing and/or hardware resources can be neglected. Hence, this method is well suited for applications where the mobile unit must be very low cost and thus, of low complexity. An alternative to hyperbolic localization is triangulation, which requires the measurement of angles among fixed reference units and the mobile target. In this work, an infrared detector array for angle of arrival measurement is presented. The array consists of multiple sensing elements that are orientated in different directions. First, the arrangement is described by a sampling system. However, it is shown that low cost integrated receivers yield various aberrations, and thus the sampling approach fails. Subsequently, a new approach named virtual filter interpolation is proposed and discussed. This approach can handle individual sensitivity characteristics of each sensor element and therefore outperforms the sampling approach. The proposed technique is qualified for extremely low cost localization, e.g. for robot navigation.

description: An observation is reported of the electroweak production of a W$^+$W$^-$ pair in association with two jets, with both W bosons decaying leptonically. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV, collected by the CMS detector at the CERN LHC. Events are selected by requiring exactly two opposite-sign leptons (electrons or muons) and two jets with large pseudorapidity separation and high dijet invariant mass. Events are categorized based on the flavor of the final-state leptons. A signal is observed with a significance of 5.6 standard deviations (5.2 expected) with respect to the background-only hypothesis. The measured fiducial cross section is 10.2$\pm$2.0 fb and this value is consistent with the standard model prediction of 9.1$\pm$0.6 fb.

description: We define and study cyclotomic quotients of affine Hecke algebras of type B. We establish an isomorphism between direct sums of blocks of these algebras and a generalisation, for type B, of cyclotomic quiver Hecke algebras which are a family of graded algebras closely related to algebras introduced by Varagnolo and Vasserot. Inspired by the work of Brundan and Kleshchev we first give a family of isomorphisms for the corresponding result in type A which includes their original isomorphism. We then select a particular isomorphism from this family and use it to prove our result.

description: A comparative cross- sectional study was conducted in Sidama Zone, SNNPR to identify reasons for the difference in contraceptive prevalence rate between the Sidama Development Program (SDP) and Family Guidance Association of Ethiopia (FGAE) supported CBD projects. Multi-stage sampling was employed to identify the study woredas. A total of 1058 reproductive age group women were interviewed from both project areas. Six hundred ninety eight from SDP and 360 from FGAE site were selected proportionate to population size. Households were selected from respective peasant associations using systematic sampling and woman from household selected randomly. Eight FGDs and four in-depth interviews were conducted in two project areas. Key informants and discussants were selected based on convenience and their position in the institution or community to participate in the study. Contraceptive prevalence rates were 40.7% and 51.6 % in SDP and FGAE areas, respectively. This showed significant difference between the two project areas (p-value, 0.01). Knowledge of at least one contraceptive method was also significantly different between the two areas with (p-value <0.01). Ninety three percent of SDP and 97% of the FGAE areas mentioned at least one modern contraceptive method. More women in FGAE (37%) than in SDP area 29.5% experienced contraceptive usediscontinuation. The main reasons were desire for more children followed by health related problems. Perception about the quality of FP services given by the CBD agents showed significant difference between the two project areas, particularly for possibility of getting method of their choice (OR=0.23(0.07,0.61)), information given about how to take the contraceptives (OR=0.18(0.07,0.49)) and methods that prevent HIV/AIDS (OR=0.54(0.30,0.94)). Standardized initial training and regular subsequent refresher training with occasional incentives given to the CBD agents showed significant association with variation in success of the agents' performances and contraceptive prevalence rate in two project areas. The study concluded that variation in the CBD agents training, level of motivation and supervision given contributed for the difference in CPR. Therefore, it is recommended that sustained motivation of CBD agents, training and supervision (with using the successful model) in both areas is imperative. In addition, cost-effectiveness analysis research is recommended in order to identify the relative cost- effectiveness of the CBD projects.

description: The efficient synthesis of a new class of oxazolidinone with strained rings is described. The allylic cis-diol as the key intermediate was first prepared via two steps starting from p-benzoquinone. Formation of the bis-carbamate groups with p-TsNCO of allylic cis-diol followed by a Pd(0) catalyzed ionization/cyclization reaction gave the corresponding oxazolidinone derivative. Oxidation and acetylation of only one alkene moiety in the compound gave a diacetate oxazolidinone compound stereoselectively. The structure of diacetate oxazolidinone compound was resolved by X-ray diffraction and the stereochemistry of the structure was determined. Characterization of all the synthesized compounds was performed by FT-IR, 1H NMR, 13C NMR, and Elemental Analysis techniques.

description: We define and study cyclotomic quotients of affine Hecke algebras of type D. We establish an isomorphism between (direct sums of blocks of) these cyclotomic quotients and a generalisation of cyclotomic quiver Hecke algebras which are a family of Z-graded algebras closely related to algebras introduced by Shan, Varagnolo and Vasserot. To achieve this, we first complete the study of cyclotomic quotients of affine Hecke algebras of type B by considering the situation when a deformation parameter p squares to 1. We then relate the two generalisations of quiver Hecke algebras showing that the one for type D can be seen as fixed point subalgebras of their analogues for type B, and we carefully study how far this relation remains valid for cyclotomic quotients. This allows us to obtain the desired isomorphism. This isomorphism completes the family of isomorphisms relating affine Hecke algebras of classical types to (generalisations of) quiver Hecke algebras, originating in the famous result of Brundan and Kleshchev for the type A.

description: Coleoid cephalopods (octopus, squid, and cuttlefish) have evolved a camera-like eye, the structure of which was distinct from that of other molluscs (i.e., mirror eye of scallop, pinhole eye of nautilus), but similar to that of marine fishes. Elucidating the genomic mechanisms that contributed to the adaptive innovations in coleoid eyes may deepen our understanding of visual system evolution. Here we apply single-cell transcriptomic analyses to elucidate the cellular characters of the vison center (optic lobe) in the gold-spot octopus, Amphioctopus fangsiao, and perform comparative genomic analyses to investigate the genomic mechanisms that underlies the visual system innovation, focusing on the lens forming and gene novelties in the vison center. We identified eight cell types in the octopod visual center (optic lobe), including proliferating cells, immature neurons, dopaminergic neurons, dopaminergic + glutamatergic neurons, cholinergic neuron, GABAergic neurons, glia cells and vascular endothelial cells. The gene novelties that highly related to the cephalopod neural innovation (i.e., protocadherin, GPCR, C2H2 ZNF and tissue-specific genes) are preferentially expressed in mature neurons in the visual center, as well as in the supra-esophageal brain, such as A. fangsiao (in press) and O. vulgaris (Styfhals et al. 2022). Comparative genomic analyses indicated that low fraction of novel genes recruited in the function of vison system, and most genes that specific expressed in the eye-related tissues have orthologues in other molluscans, yet the expression domains of these genes were not restricted in the eye-related tissues. Gene duplication and functional diversities of the existing genes may contribute to the visual system innovation in coleoids, such as the tandem duplication of S-crystallin genes, and high expression of r-opsin in the non-visual tissues. The present study suggested that the gene novelties in the mature neurons might have been one of the major driving forces behind the coleoid visual system innovation, highlighting the complexity of which as a combined result of several genomic mechanisms, including recruitments of novel genes, function diversities of pre-existing gene functions and expansion of gene families.
