description: Given a filtration function on a finite simplicial complex, stability theorem of persistent homology states that the corresponding barcode is continuous with respect to changes in the filtration function. However, due to the discrete setting of simplicial complexes, the critical simplices terminating matched bars cannot change continuously for arbitrary perturbations of filtration functions. In this paper we provide a sufficient condition for rigidity of a terminal simplex, i.e., a condition on $ε> 0$ implying that the terminal simplex of a homology class or a bar in persistent homology remains constant through $ε$-perturbations of filtration function. The condition for a homology class or a bar in dimension n depends on the barcodes in dimensions n and n+1.

description: In the present work we modified the procedure for isolation of naphthoquinones α-methylbutyrylshikon (1), acetylshikonin (2) and β-hydroxyisovalerylshikonin (3) from Onosma visianii Clem. We also investigated possible mechanisms of 1, 2 and 3 as antitumor agents. Accordingly, we estimated concentrations of superoxide anion radical (O2.-), nitrite (NO2 -) and glutathione in HCT-116 and MDA-MB-231 cell lines. Compounds 1 and 3 expressed significant prooxidative activity, while all tested compounds exhibited significant increase in nitrite levels. Also, all examined compounds significantly increased the concentration of oxidized glutathione (GSSG), suggesting significant prooxidative disbalance. The levels of reduced glutathione (GSH) were also elevated as a part of antioxidative cell response. The data indicate that induced oxidative imbalance could be one of the triggers for previously recorded decreased viability of HCT-116 and MDA-MB-231 cells exposed to tested naphthoquinone derivatives. Moreover, we examined interactions mode of compounds 1, 2 and 3 with CT-DNA as one of the crucial targets of many molecules that express cytotoxic activity. The results obtained by UV-visible, fluorescence and molecular docking study revealed that 1, 2 and 3 bound to CT-DNA through minor groove binding. Furthermore, the interactions between HSA and 1, 2 and 3 were examined employing the same methods as for the CT-DNA interaction study. Based on the obtained results, it can be concluded that naphthoquinones 1, 2 and 3 could be effectively transported by human serum albumin. As a conclusion, this study provides further insight of antitumor activity of selected naphthoquinones.

description: Understanding the crossover from quantum to classical transport phenomena has become of fundamental importance not only for technological applications due to the creation of sub-10nm transistors - an important building block of our modern life - but also for elucidating the role played by quantum mechanics in the evolutionary fitness of biological complexes. This article provides a basic introduction into the nature of charge and energy transport in the quantum and classical regimes. It discusses the characteristic transport properties in both limits, and demonstrates how they can be connected through the loss of quantum mechanical coherence. The salient features of the crossover physics are identified, and their importance in opening new transport regimes and in understanding efficient and robust energy transport in biological complexes are demonstrated.

Year: 2022

description: This research is with a mixed approach. The study population quantitatively\nconsisted of all Urmia’s high school principals and assistant principals (n=452).\nCochran’s formula was used to determine this quantity. 204 subjects were chosen\nas the study sample through stratified random sampling. Qualitatively, the study\npopulation who consisted of the professors of education faculty, school principals\nand experts of education departments was chosen by a purposive sampling—\nsnowball. That is to say, 13 subjects were chosen by the theoretical saturation\ntechnique. To collect the quantitative data, a researcher-made questionnaire\nensuring a face and content validity of 0.88 was developed by the experts. The\nqualitative data were collected according to semi-structured interviews. The data\nanalysis was performed by two software programs—SPSS and MAXQDA. The\nresults of the quantitative findings suggested that the challenges and obstacles to\nthe leadership of professional learning communities are not in satisfactory\ncondition in schools. Furthermore, the results of Friedman’s rank test indicated\nthat the highest rank mean relates to the organizational challenges and obstacles,\nwhile the lowest rank mean was depicted by the individual challenges and barriers.\nAccording to the results of the qualitative findings, four strategies were suggested\nto address the challenges and obstacles to the leadership of professional learning\ncommunities as follows; organizational strategies, educational and selection\nstrategies, cultural strategies, and leadership strategies

Publisher: name: The University Of Kurdistan
Year: 2022

description: Education is the most important organization emerging from within the society and at\nthe same time its creator and builder, and its impact on the progress of the society is\nvital and tangible. In the education system of any country, the primary course has a high\nposition, sensitivity, and importance. It is considered the most important academic\ncourse. This research4 was conducted with the aim of identifying the components of\nauthentic leadership competence in primary schools. Also, in terms of practical purpose,\nin terms of data type, it is qualitative research and in terms of method, it is\nphenomenological research. The method and tool used for data collection is a semistructured\ninterview with experts in the field under study. The participants in the\nresearch were managers, professors, and experts in the field of management and\nleadership, and sampling was done by snowball method until the theoretical saturation\nlimit was reached. To determine reliability and trustworthiness, three techniques of\nreliability, transferability and confirmability have been used from the finding. After\nanalyzing the data from a semi-structured interview with 15 managers, professors, and\nexperts in the field of management and leadership, 184 concepts (decoder), 15\nsubcategories and 5 categories (knowledge, attitude, skills, characteristics and abilities,\nauthentic leadership). was extracted and finally the results of this research were\nexamined with the results of previous researches and solutions were proposed to\nimprove the use of authentic leadership in Primary schools

Components of the Culture of Obedience in Iranian Schools
Publisher: name: The University Of Kurdistan
Year: 2022

description: The role of culture in planning and implementing educational reforms and in impacting\nthe quality of the education system has rarely been discussed. This study aims to identify\nthe features of culture in governmental primary schools for girls in Iran aged 7‒12 years.\nUsing an ethnographic approach, qualitative data were collected and analysed. The data\nwere collected based on a triangulation strategy, through observation, in-depth interviews\nwith teachers, and content analysis of the Document for Fundamental Transformation of\nthe Education System. Thematic analysis was used to discover, analyse, and interpret the\npattern of data meanings.\nThe findings reveal that specific components represent the culture of these schools: a\nuniform education system, bureaucratic structure of schools, square-shape architecture of\nschools, national curriculum, arbitrary relationships between members of the school\ncommunity, and the professional development of teachers based on the top-down\ncommand. The shared values of school members and behaviour norms are concerned with\nthe exact execution of policies and plans issued in the form of circulars from the Ministry\nof Education, which shape the daily activities of school members; this has led to the\nemergence of a culture of obedience, wherein the members comply with the expectations,\nprescribed policies, and plans set by the Ministry of Education. Although studies\nacknowledge the importance of identifying cultural context, school culture has rarely been\ninvestigated in governmental primary schools for girls in Iran. This study highlights the\nrole of education policymakers in maintaining and solidifying the existing culture in these\nschools
Mixed quantum-classical dynamics using collective electronic variables: A better alternative to electronic friction theories

description: An accurate description of nonadiabatic dynamics of molecular species on metallic surfaces poses a serious computational challenge associated with a multitude of closely-spaced electronic states. We propose a mixed quantum-classical scheme that addresses this challenge by introducing collective electronic variables. These variables are defined through analytic block-diagonalization applied to the time-dependent Hamiltonian matrix governing the electronic dynamics. We compare our scheme with the Ehrenfest approach and with a full-memory electronic friction model on a one-dimensional "adatom + atomic chain" model. Our simulations demonstrate that collective-mode dynamics with only few (2-3) electronic variables is robust and can describe a variety of situations: from a chemisorbed atom on an insulator to an atom on a metallic surface. Our molecular model also reveals that the friction approach is prone to unpredictable and catastrophic failures.

description: We present an analysis of the gamma-ray measurements by the Large Area Telescope onboard the \textit{Fermi Gamma-ray Space Telescope} in the region of the supernova remnant~(SNR) Monoceros Loop~(G205.5$+$0.5). The brightest gamma-ray peak is spatially correlated with the Rosette Nebula, which is a molecular cloud complex adjacent to the southeast edge of the SNR. After subtraction of this emission by spatial modeling, the gamma-ray emission from the SNR emerges, which is extended and fit by a Gaussian spatial template. The gamma-ray spectra are significantly better reproduced by a curved shape than a simple power law. The luminosities between 0.2--300~GeV are $\sim$~$4 \times 10^{34}$~erg~s$^{-1}$ for the SNR and $\sim$~$3 \times 10^{34}$~erg~s$^{-1}$ for the Rosette Nebula, respectively. We argue that the gamma rays likely originate from the interactions of particles accelerated in the SNR. The decay of neutral pions produced in nucleon-nucleon interactions of accelerated hadrons with interstellar gas provides a reasonable explanation for the gamma-ray emission of both the Rosette Nebula and the Monoceros SNR.

On Tjurina Ideals of Hypersurface Singularities

Publisher: name: arXiv
Year: 2022
Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: The Tjurina ideal of a germ of an holomorphic function $f$ is the ideal of $\mathscr{O}_{\mathbbm{C}^n,0}$ - the ring of those germs at $0\in\mathbbm{C}^n$ - generated by $f$ itself and by its partial derivatives. Here it is denoted by $T(f)$. The ideal $T(f)$ gives the structure of closed subscheme of $(\mathbbm{C}^n,0)$ to the hypersurface singularity defined by $f$, being an object of central interest in Singularity Theory. In this note we introduce \emph{$T$-fullness} and \emph{$T$-dependence}, two easily verifiable properties for arbitrary ideals of germs of holomorphic functions. These two properties allow us to give necessary and sufficient conditions on an ideal $I\subset \mathscr{O}_{\mathbbm{C}^n,0}$, for the equation $I=T(f)$ to admit a solution $f$.

description: Contrary to orthogonal multiple-access (OMA), non-orthogonal multiple-access (NOMA) schemes can serve a pool of users without exploiting the scarce frequency or time domain resources. This is useful in meeting the sixth generation (6G) network requirements, such as, low latency, massive connectivity, users fairness, and high spectral efficiency. On the other hand, content caching restricts duplicate data transmission by storing popular contents in advance at the network edge which reduces 6G data traffic. In this survey, we focus on cache-aided NOMA-based wireless networks which can reap the benefits of both cache and NOMA; switching to NOMA from OMA enables cache-aided networks to push additional files to content servers in parallel and improve the cache hit probability. Beginning with fundamentals of cache-aided NOMA technology, we summarize the performance goals of cache-aided NOMA systems, present the associated design challenges, and categorize related recent literature based on their application verticals. Concomitant standardization activities and open research challenges are highlighted as well.

The role of self-development on job performance of school principals: A case study of secondary school principals in Isfahan
Publisher: name: The University Of Kurdistan
Year: 2022

description: The present study analyses the link between self-development and job performance of\nsecondary school principals in Isfahan. The study is applied in terms of purpose and done\nby a qualitative-quantitative combined method. In the qualitative section, we use the\nthematic analysis strategy and in the quantitative section, we test the proposed research\nmodel through structural equation modelling. The statistical population included all\nsecondary school principals in Isfahan, Iran (n = 323), of whom 175 were selected via\nstratified sampling method. The data were collected via interviews and a validated\nresearcher-made self-development questionnaire with a reliability coefficient of 0.85.\nMoreover, Paterson’s (1989) standard job performance questionnaire was applied. The\nqualitative findings show 3 main categories with 16 sub-categories for the selfdevelopment\nvariable and the quantitative findings indicate that school principals’ selfdevelopment\ncorrelates with their job performance (correlation coefficient = 0.68). The\nstructural equations modeling of principals’ self-development and job performance with\napproved fit indices revealed that self-development affects job performance (impact\ncoefficient = 0.749). The results of stepwise regression indicated that individual and\norganizational components can predict 40% of principal’s job performance. The present\nstudy shows that self-improvement through individual and organizational components\naffect the job performance of school principals. So school principals will definitely have\nbetter job performance if they can evaluate themselves, control their behaviors, gain selfawareness,\nand stay motivated by setting goals and planning

description: Periodically-driven open quantum systems that never thermalize exhibit a discrete time-crystal behavior, a non-equilibrium quantum phenomenon that has shown promise in quantum information processing applications. Measurements of time-crystallinity are currently limited to (magneto-) optical experiments in atom-cavity systems and spin-systems making it an indirect measurement. We theoretically show that time-crystallinity can be measured directly in the charge-current from a spin-less Hubbard ladder, which can be simulated on a quantum-dot array. We demonstrate that one can dynamically tune the system out and then back into the time-crystal phase, proving its robustness against external forcings. These findings motivate further theoretical and experimental efforts to simulate the time-crystal phenomena in current-carrying nano-scale systems.

Publisher: name: arXiv

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: The current state of the link problem between radio and optical celestial reference frames is considered. The main objectives of the investigations in this direction during the next few years are the preparation of a comparison and the mutual orientation and rotation between the optical {\it Gaia} Celestial Reference Frame (GCRF) and the 3rd generation radio International Celestial Reference Frame (ICRF3), obtained from VLBI observations. Both systems, ideally, should be a realization of the ICRS (International Celestial Reference System) at micro-arcsecond level accuracy. Therefore, the link accuracy between the ICRF and GCRF should be obtained with similar error level, which is not a trivial task due to relatively large systematic and random errors in source positions at different frequency bands. In this paper, a brief overview of recent work on the GCRF--ICRF link is presented. Additional possibilities to improve the GCRF--ICRF link accuracy are discussed. The suggestion is made to use astrometric radio sources with optical magnitude to 20$^m$ rather than to 18$^m$ as currently planned for the GCRF--ICRF link. In addition, the use of radio stars is also a prospective method to obtain independent and accurate orientation between the Gaia frame and the ICRF.

description: The features of non-stationary multi-component signals are often difficult to be extracted for expert systems. In this paper, a new method for feature extraction that is based on maximization of local Gaussian correlation function of wavelet coefficients and signal is presented. The effect of empirical mode decomposition (EMD) to decompose multi-component signals to intrinsic mode functions (IMFs), before using of local Gaussian correlation is discussed. The experimental vibration signals from two gearbox systems are used to show the efficiency of the presented method. Linear support vector machine (SVM) is utilized to classify feature sets extracted with the presented method. The obtained results show that the features extracted in this method have excellent ability to classify faults without any additional feature selection; it is also shown that EMD can improve or degrade features according to the utilized feature reduction method.

description: The loss of ultracold trapped atoms due to deeply inelastic reactions has previously been taken into account in effective field theories for low-energy atoms by adding local anti-Hermitian terms to the effective Hamiltonian. Here we show that when multi-atom systems are considered, an additional modification is required in the equation governing the density matrix. We define an effective density matrix by tracing over the states containing high-momentum atoms produced by deeply inelastic reactions. We show that it satisfies a Lindblad equation, with local Lindblad operators determined by the local anti-Hermitian terms in the effective Hamiltonian. We use the Lindblad equation to derive the universal relation for the two-atom inelastic loss rate for fermions with two spin states and the universal relation for the three-atom inelastic loss rate for identical bosons.

Year: 2022

description: Abstract, \nThis study was conducted based on dual purposes; the first purpose was validation of the leadership creativity assessment scale from the perspective of teachers; the second purpose was to establish a qualification profile of the principals` leadership creativity using a standard tool. The current research applied a positivist epistemological orientation with a quantitative approach and evaluation method. The study population involved 1256 Sanandaj high school teachers of which 296 teachers (both males and female) were selected by stratified random sampling. In evaluating the validity of managerial creativity questionnaire factor analysis was used and in assessing its reliability of it, Cronbach’s alpha coefficient was applied to assess principles` of managerial creativity by teachers and the influence of demographic variables on teachers` assessment. Based on the findings of the study teachers evaluated their principals` level of Leadership creativity at a high level in their workplace. Moreover, it was revealed that teachers` demographic variables had no significant correlation to the scores of the Leadership creativity assessment.

description: We investigate segregation behavior of additive elements M (= Ni, Cr) at the C11b/D8m interface for MoSi2- Mo5Si3 alloys, based on first-principles calculation. We first find energetically stable interface structure with interface energy of 0.08 eV/A^2. Based on the stable interface, segregation energy for additive elements is calcu- lated for individual atomic layer, which is applied to Monte Carlo statistical simulation under grand-canonical ensemble to quantitatively predict interface segregation profile. We find that our simulation successfully capture the characteristics in measured segregation tendency of (i) Similarity in strong segregation at interface both for Ni and Cr compared with bulk composition, and (ii) stronger segregation for Ni than for Cr, which can be mainly attributed to differences in calculated segregation energy. The present results indicate that measured segregated interface for MoSi2-Mo5Si3 alloys can be thermodynamically stable.

description: On December 13th, 2022, the BonaRes Centre organized a virtual workshop on research data management. The session was hosted by the BonaRes Repository coordinator, Maureen Fonji Atemkeng, who was accompanied/supported by the research data management group leader, Nikolai Svoboda, soil scientist Carsten Hoffman, geo-informatician Abraham Tula and Xenia Specka, the head of the data infrastructure working group in ZALF (Leibniz-Zentrum für Agrarlandschaftsforschung e.V.). The workshop's objectives were to first explain the concepts of FAIR principles to participants, then to enlighten them on how to make data FAIR, to explain the simplified version of data publication workflow used by the BonaRes Centre, and to walk participants through the BonaRes Repository explaining how they could search and reuse data. A group work took place to allow participants to explore the repository, download, and evaluate a dataset in accordance with the FAIR principles. Participants were asked at the end of the workshop if their workshop outcomes had been met. Eighty three (83%) percent of the participants felt that their workshop outcome was fulfilled, while 8% said it was met in some way and the remaining 8% stated it was strongly met.

description: Quantum interference in nano-electronic devices could lead to reduced-energy computing and efficient thermoelectric energy harvesting. When devices are shrunk down to the molecular level it is still unclear to what extent electron transmission is phase coherent, as molecules usually act as scattering centres, without the possibility of showing particle-wave duality. Here we show electron transmission remains phase coherent in molecular porphyrin nanoribbons, synthesized with perfectly defined geometry, connected to graphene electrodes. The device acts as a graphene Fabry-Pérot interferometer, allowing direct probing of the transport mechanisms throughout several regimes, including the Kondo one. Electrostatic gating allows measurement of the molecular conductance in multiple molecular oxidation states, demonstrating a thousand-fold increase of the current by interference, and unravelling molecular and graphene transport pathways. These results demonstrate a platform for the use of interferometric effects in single-molecule junctions, opening up new avenues for studying quantum coherence in molecular electronic and spintronic devices.

description: Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextuality (RC). We define RC as the minimum number of non-contextual behaviors that are needed to simulate a contextual behavior. We show that the logarithm of RC is a natural contextuality measure satisfying several properties considered in the spirit of the resource-theoretic approach. The properties include faithfulness, monotonicity, and additivity under tensor product. We also give examples of how to construct contextual behaviors with an arbitrary value of RC exhibiting a natural connection between this quantifier and the arboricity of an underlying hypergraph. We also discuss exemplary areas of research in which the new measure appears as a natural quantifier.

description: We have been developing the monolithic active pixel detector "XRPIX" onboard the future X-ray astronomical satellite "FORCE". XRPIX is composed of CMOS pixel circuits, SiO2 insulator, and Si sensor by utilizing the silicon-on-insulator (SOI) technology. When the semiconductor detector is operated in orbit, it suffers from radiation damage due to X-rays emitted from the celestial objects as well as cosmic rays. From previous studies, positive charges trapped in the SiO2 insulator are known to cause the degradation of the detector performance. To improve the radiation hardness, we developed XRPIX equipped with Double-SOI (D-SOI) structure, introducing an additional silicon layer in the SiO2 insulator. This structure is aimed at compensating for the effect of the trapped positive charges. Although the radiation hardness to cosmic rays of the D-SOI detectors has been evaluated, the radiation effect due to the X-ray irradiation has not been evaluated. Then, we conduct an X-ray irradiation experiment using an X-ray generator with a total dose of 10 krad at the SiO2 insulator, equivalent to 7 years in orbit. As a result of this experiment, the energy resolution in full-width half maximum for the 5.9 keV X-ray degrades by 17.8 $\pm$ 2.8% and the dark current increases by 89 $\pm$ 13%. We also investigate the physical mechanism of the increase in the dark current due to X-ray irradiation using TCAD simulation. It is found that the increase in the dark current can be explained by the increase in the interface state density at the Si/SiO2 interface.

A new framework for magnetohydrodynamic simulations with anisotropic pressure

description: We describe a new theoretical and numerical framework of the magnetohydrodynamic simulation incorporated with an anisotropic pressure tensor, which can play an important role in a collisionless plasma. A classical approach to handle the anisotropy is based on the double adiabatic approximation assuming that a pressure tensor is well described only by the components parallel and perpendicular to the local magnetic field. This gyrotropic assumption, however, fails around a magnetically neutral region, where the cyclotron period may get comparable to or even longer than a dynamical time in a system, and causes a singularity in the mathematical expression. In this paper, we demonstrate that this singularity can be completely removed away by the combination of direct use of the 2nd-moment of the Vlasov equation and an ingenious gyrotropization model. Numerical tests also verify that the present model properly reduces to the standard MHD or the double adiabatic formulation in an asymptotic manner under an appropriate limit.

description: Energy system models underpin decisions by energy system planners and operators. Energy system modelling faces a transformation: accounting for changing meteorological conditions imposed by climate change. To enable that transformation, a community of practice in energy-climate modelling has started to form that aims to better integrate energy system models with weather and climate models. Here, we evaluate the disconnects between the energy system and climate modelling communities, then lay out a research agenda to bridge those disconnects. In the near-term, we propose interdisciplinary activities for expediting uptake of future climate data in energy system modelling. In the long-term, we propose a transdisciplinary approach to enable development of (1) energy-system-tailored climate datasets for historical and future meteorological conditions and (2) energy system models that can effectively leverage those datasets. This agenda increases the odds of meeting ambitious climate mitigation goals by systematically capturing and mitigating climate risk in energy sector decision making.
