description: A deep exploration of the parameter space that relates the interacting equation of state with the bag constant B, and the interaction parameter a, is fundamental for the construction of diverse models of quark stars. In particular, the anisotropy of quark stars with a well-motivated quantum chromodynamics (QCD) equation of state is presented here. The contribution of the fourth order corrections parameter ($\mathrm{a}$) of the QCD perturbation on the radial and tangential pressure generate significant effects on the mass-radius relation and the stability of the quark star. An adequate set of solutions for several values of the bag factor and the interaction parameter are used in order to calculate the relation between the mass, radius, density, compactness, and consequently the maximum masses and the stability. Therefore, while the more interactive quark solution leads to higher masses, the weak interaction among quarks give solutions similar to the widely known MIT bag model.

description: A quantum mechanical model is used to derive a generalized Landau-Lifshitz equation for a magnetic moment, including fluctuations and dissipation. The model reproduces the Gilbert-Brown form of the equation in the classical limit. The magnetic moment is linearly coupled to a reservoir of bosonic degrees of freedom. Use of generalized coherent states makes the semiclassical limit more transparent within a path-integral formulation. A general fluctuation-dissipation theorem is derived. The magnitude of the magnetic moment also fluctuates beyond the Gaussian approximation. We discuss how the approximate stochastic description of the thermal field follows from our result. As an example, we go beyond the linear-response method and show how the thermal fluctuations become anisotropy-dependent even in the uniaxial case.

description: As there have been long progress in plant genomics research and applied research in the area has reached to genetically modified crops and its varieties.Here arises need of organised and curated repository of information related past research in the field.
Apart from it high-throughput sequencing and parallel computing has revolutionized the applied genomics research resulting into voluminous data in terms of number and size. It requires organisation,storage and retrieval mechanism so that to get facilitated from those data and to overcome information gap.
Database Management System (DBMS) has paved a way for storage and retrieval of the available information.
There exists databases related animals and organisms ( prokaryotes and eucaryotes ) but these initiatives are lacking in the the field of plant research specially at the level of genomics and proteomics.
Databases related plant genes , mRNA and other non- coding RNAs, transcription factors and other genomic components are beneficial in plant disease biology , stress response studies,biomarker discovery in the field of translational medicine, nutritional development as well as increase in the productivity of certain crops. Proteome classification on the basis of tissue specificity will be benefiting in protein-protein and protein-gene network

description: Context: Osteoarthritis (OA) is a degenerative joint disease with damage to the articular cartilage. Active production of inflammatory cytokine/chemokine and matrix metalloproteinases may be found during the progression of OA. Isorhamnetin had the effects of anti-inflammatory, antioxidant, anti-ischemia, anti-atherosclerotic hepatoprotective and anticancer activities. Objective: Our study was focused on the effects of isorhamnetin treatment in OA. Materials and methods: We used monosodium iodoacetate (MIA)-induced OA rats to evaluate the effects of isorhamnetin related anti-inflammatory process. The rats in all groups were sacrificed on four weeks post-MIA injection. The measurements of knee joint swelling, histological analysis, serum inflammatory biomarkers and western blot were evaluated. Results: We found that isorhamnetin may reduce MIA-induced knee swelling by significantly reduction of articular cartilage damage.in rats. Suppression of pro-inflammatory cytokines production was found after isohamnetin treatment. Isorhamnetin inhibited the production of NO and PGE2, and the expression of iNOS and COX-2. The production of COMP, CTX-II and osteopontin (OPN) were also inhibited in MIA-induced OA rats. Discussion and conclusions: Isorhamnetin may modulate the inflammatory progression of OA in MIA-induced OA rats. The prevention of cartilage damage was found in OA after adequate isorhamnetin treatment. Isorhamnetin may serve as a potential agent for the management of OA.

description: We calculate using perturbative calculations and Ward identities the basic parameters of the Fermi Liquid: the scattering vertex, the Landau interaction function, the effective mass, specific heat, and physical susceptibilities for a model of two-dimensional (2D) fermions with a short ranged interaction at non-zero temperature. The leading temperature dependence of the spin components of the scattering vertex, the Landau function, and the spin susceptibility is found to be linear. We find that the standard T=0 relationships for a Galilean-invariant Fermi Liquid are violated by finite-temperature terms. The coefficients in the temperature corrections to these relationships involve a subtle interplay between contributions from small and large ($\sim 2k_F$) momentum processes. A connection with previous studies of the 2D Fermi-Liquid parameters is discussed. We conclude that the linear leading temperature dependence of the parameters is a generic feature of the 2D Fermi Liquid.

description: A multi pass shell and tube heat exchanger with 3 tubes modelling is done using CATIA and meshing has done using ICEM CFD software, simulations has done by using CFD-FLUENT software. Using Fluent, computational fluid dynamics software the pressure drop, heat transfer characteristics of Al2O3-water nanofluid, and Distilled water are analyzed under turbulent flow condition. Nanofluid such as Al2O3-H2O is used as cooling medium instead of Distilled water. Finally the CFD simulated results are compared with experimental results. The effects of Peclet number, volume concentration of suspended nanoparticles, and particle type on the heat transfer characteristics were investigated. Based on the results, adding of nanoparticles to the base fluid (Distilled water) causes the significant enhancement of heat transfer characteristics.

description: Introduction: Cytochrome bc1 (Cytbc1) complex is a homodimer consisting of 11 subunits essential in promoting electron transfer which maintains membrane potential in eukaryotes. In Plasmodium, cytochrome b (PfCytb) subunit has two heme groups and is a validated drug target for the inhibition of the cellular respiration metabolic pathway. The protein interacts with iron-sulfur protein (ISP) containing a [2FE-2S] cluster. Iron metals in these co-factors have redox centers where oxidation and reduction occur to aid in catalysis. Prior to conducting inhibitory drug design, accurate force field parameters for each of these co-factors are important in studying molecular dynamics (MD) simulations. This work derives and validates optimal force-field parameters appropriate for PfCytb-ISP complex.

Methods: Geometry optimization and quantum mechanics/molecular mechanic calculations for force-field generation for the cofactors were done using Amberff14SB force-field. For validation, MD simulations were performed in GROMACS at 310K and 1 bar pressure. The root-mean-square deviations were analyzed.

Results: Force-field parameters (distances, charges and energies) were generated. The MD simulations showed system stability, and strong coupling between the cofactors and coordinating Histidine and Cysteine residues.

Conclusion: These parameters hold metal ions in coordinating sphere of hemes and [2FE-2S] cluster thus they mirror the functionality of the co-factors as in their natural state.

description: We propose a novel application of self-attention networks towards grammar induction. We present an attention-based supertagger for a refined type-logical grammar, trained on constructing types inductively. In addition to achieving a high overall type accuracy, our model is able to learn the syntax of the grammar's type system along with its denotational semantics. This lifts the closed world assumption commonly made by lexicalized grammar supertaggers, greatly enhancing its generalization potential. This is evidenced both by its adequate accuracy over sparse word types and its ability to correctly construct complex types never seen during training, which, to the best of our knowledge, was as of yet unaccomplished.

Several small Josephson junctions in a Resonant Cavity: Deviation from the Dicke Model

description: We have studied quantum-mechanically a system of several small identical Josephson junctions in a lossless single-mode cavity for different initial states, under conditions such that the system is at resonance. This system is analogous to a collection of identical atoms in a cavity, which is described under appropriate conditions by the Dicke model. We find that our system can be well approximated by a reduced Hamiltonian consisting of two levels per junction. The reduced Hamiltonian is similar to the Dicke Hamiltonian, but contains an additional term resembling a dipole-dipole interaction between the junctions. This extra term arises when states outside the degenerate group are included via degenerate second-order (Löwdin) perturbation theory. As in the Dicke model, we find that, when N junctions are present in the cavity, the oscillation frequency due to the junction-cavity interaction is enhanced by $\sqrt{N}$. The corresponding decrease in the Rabi oscillation period may cause it to be smaller than the decoherence time due to dissipation, making these oscillations observable. Finally, we find that the frequency enhancement survives even if the junctions differ slightly from one another, as expected in a realistic system.

description: Public speaking is a challenging task that requires practice. Virtual Reality allows to present realistic public speaking scenarios in this regard, however, the role of the virtual audience during practice remains unknown. In the present study, 73 participants completed a Virtual Reality practice session while audience was manipulated to be supportive or unsupportive or presentations were practiced without audience. Importantly, following the virtual practice, participants held the presentation during a real university course via Zoom. We measured emotional experience, self-efficacy, and the subjective evaluation of performance at baseline, after VR practice, and after the real presentation. Additionally, participants’ performance in the real presentation was evaluated by instructors (blinded to condition). Supportive in contrast to unsupportive audiences led to more positive believes about one’s own performance, while there were no changes in beliefs in the group without audience. Importantly, practice in front of a supportive compared to unsupportive audience resulted in a more positive evaluation of speaker confidence in real-life public speaking as rated by the instructors. These results demonstrate an impact of virtual social feedback during public speaking on subsequent subjective performance evaluation. This may increase self-confidence resulting in actual improved public speaking performance in real-life.

description: In this paper we present a measurement of the natural widths of $Σ_c^0$ and $Σ_c^{++}$. Using data from the FOCUS experiment, we find $Γ(Σ_c^0) = 1.55 +0.41/-0.37 \pm 0.38$ MeV/c^2 and $Γ(Σ_c^0) = 2.05 +0.41/-0.38 \pm 0.38$ MeV/c^2. The first errors are statistical, the second systematic. These results are obtained with a sample of 913 $Σ_c^0 \to Λ_c^+ π^-$ decays and 1110 $Σ_c^++ \to Λ_c^+ π^+$ decays. These results are compared with recent theoretical predictions. PACS numbers: 14.20.Lq 13.30Eg

description: This paper explores how the Higher Institute of Dramatic Arts (HIDA) in Damascus achieved an exceptional degree of prestige in Syrian cultural life. Although operating under a dictatorship in a conservative country, HIDA still enjoyed unusual margins of curricula autonomy and free expression in a country that repressed other cultural and educational sectors. Like in many socialist countries in the Cold War, Syrian intellectuals were challenged by several factors, chief of which was the ability to confront the dominant status quo without being accused of disloyalty. Yet, while the theatre institute became ‘the place of the intellectuals’ at the national level, the interpretation of intellectualism provoked controversies inside the institute between the acting and the theatre studies departments. It is argued that the rise of commercial television and the success of accomplished alumni were among the reasons that gave the institute its prominent position in Syria and in many other Arabic-speaking countries. These two antithetical developments – the rise of serialized television drama, and the changing status of the intellectual – played a significant role in shaping the image of the institute, its curricula and in determining the image of the intellectual in Syria.

description: We discuss the entropy of a circular polymer under a topological constraint. We call it the {\it topological entropy} of the polymer, in short. A ring polymer does not change its topology (knot type) under any thermal fluctuations. Through numerical simulations using some knot invariants, we show that the topological entropy of a stiff ring polymer with a fixed knot is described by a scaling formula as a function of the thickness and length of the circular chain. The result is consistent with the viewpoint that for stiff polymers such as DNAs, the length and diameter of the chains should play a central role in their statistical and dynamical properties. Furthermore, we show that the new formula extends a known theoretical formula for DNA knots.

description: The Ruppeiner geometry of thermodynamic fluctuations provides a powerful diagnostic of black hole microstructures. We investigate this for charged AdS black holes and find that while an attractive microstructure interaction dominates for most parameter ranges, a weak repulsive interaction dominates for small black holes of high temperature. This unique property distinguishes the black hole system from that of a Van der Waals fluid, where only attractive microstructure interactions are found. We also find two other novel universal properties for charged black holes. One is that the repulsive interaction is independent of the black hole charge and temperature. The other is that the behavior of the Ruppeiner curvature scalar near criticality is characterized by a dimensionless constant that is identical to that for a Van der Waals fluid, providing us with new insight into black hole microstructures.

description: In this work the complete valence-band structure of the molybdenum dichalcogenides MoS_2, MoSe_2, and alpha-MoTe_2 is presented and discussed in comparison. The valence bands have been studied using both angle-resolved photoelectron spectroscopy (ARPES) with synchrotron radiation, as well as, ab-initio band-structure calculations. The ARPES measurements have been carried out in the constant-final-state (CFS) mode. The results of the calculations show in general very good agreement with the experimentally determined valence-band structures allowing for a clear identification of the observed features. The dispersion of the valence bands as a function of the perpendicular component k_perp of the wave vector reveals a decreasing three-dimensional character from MoS_2 to alpha-MoTe_2 which is attributed to an increasing interlayer distance in the three compounds. The effect of this k_perp dispersion on the determination of the exact dispersion of the individual states as a function of k_parallel is discussed. By performing ARPES in the CFS mode the k_parallel-component for off-normal emission spectra can be determined. The corresponding k_perp-value is obtained from the symmetry of the spectra along the GammaA, KH, and ML line, respectively.

description: We consider nonequilibrium probabilistic dynamics in logistic-like maps $x_{t+1}=1-a|x_t|^z$, $(z>1)$ at their chaos threshold: We first introduce many initial conditions within one among $W>>1$ intervals partitioning the phase space and focus on the unique value $q_{sen}<1$ for which the entropic form $S_q \equiv \frac{1-\sum_{i=1}^{W} p_i^q}{q-1}$ {\it linearly} increases with time. We then verify that $S_{q_{sen}}(t) - S_{q_{sen}}(\infty)$ vanishes like $t^{-1/[q_{rel}(W)-1]}$ [$q_{rel}(W)>1$]. We finally exhibit a new finite-size scaling, $q_{rel}(\infty) - q_{rel}(W) \propto W^{-|q_{sen}|}$. This establishes quantitatively, for the first time, a long pursued relation between sensitivity to the initial conditions and relaxation, concepts which play central roles in nonextensive statistical mechanics.

description: A dominating set of a graph $G$ is a set $D\subseteq V_G$ such that every vertex in $V_G-D$ is adjacent to at least one vertex in $D$, and the domination number $γ(G)$ of $G$ is the minimum cardinality of a dominating set of $G$. In this paper we provide a new characterization of bipartite graphs whose domination number is equal to the cardinality of its smaller partite set. Our characterization is based upon a new graph operation.

description: To get a job as a seafarer in the global maritime industry, thousands of male Filipino youths work for free as ‘utility men’ for manning agencies that supply seafarers to ship operators around the world. Based on ethnographic fieldwork and approached from a moral economy perspective, this article examines how manning agencies and utility men differentially rationalize this exploitative work (utility manning). Manning agencies use it as a technology of servitude that, through physical and verbal abuse and other techniques, enforces docility to prepare utility men for the harsher conditions on-board a ship. In contrast, utility men use it as a technology of imagination, gleaning from it a capacity to shape their future. Faced with few social possibilities in the Philippines, they deploy servitude as a strategy for attaining economic mobility and male adulthood.

description: Background: Magnetic nanoparticles (MNPs) generate heat when exposed to an alternating magnetic field. Consequently, MNPs are used for magnetic fluid hyperthermia (MFH) for cancer treatment, and have been shown to increase the efficacy of chemotherapy and/or radiation treatment in clinical trials. A downfall of current MFH treatment is the inability to deliver sufficient heat to the tumor due to: insufficient amounts of MNPs, unequal distribution of MNPs throughout the tumor, or heat loss to the surrounding environment. Objective: In this study, the objective was to identify MNPs with high heating efficiencies quantified by their specific absorption rate (SAR). Methods: A panel of 31 commercially available MNPs were evaluated for SAR in two different AMFs. Additionally, particle properties including iron content, hydrodynamic diameter, core diameter, magnetic diameter, magnetically dead layer thickness, and saturation mass magnetization were investigated. Results: High SAR MNPs were identified. For SAR calculations, the initial slope, corrected slope, and Box–Lucas methods were used and validated using a graphical residual analysis, and the Box–Lucas method was shown to be the most accurate. Other particle properties were identified and examined for correlations with SAR values. Positive correlations of particle properties with SAR were found, including a strong correlation for the magnetically dead layer thickness. Conclusions: This work identified high SAR MNPs for hyperthermia, and provides insight into properties which correlate with SAR which will be valuable for synthesis of next-generation MNPs. SAR calculation methods must be standardized, and this work provides an in-depth analysis of common calculation methods.
Electronic structure of superconducting MgB2 and related binary and ternary borides

description: First principles FLMTO-GGA electronic structure calculations of the new medium-$T_C$ superconductor (MTSC) $MgB_2$ and related diborides indicate that superconductivity in these compounds is related to the the existence of $p_{x,y}$-band holes at the $Γ$ point. Based on these calculations, we explain the absence of medium-$T_C$ superconductivity for $BeB_2$, $AlB_2$ $ScB_2$ and $YB_2$. The simulation of a number of $MgB_2$-based ternary systems using a supercell approach demonstrates that (i) the electron doping of $MgB_2$ (i.e., $MgB_{2-y}X_y$ with X=Be, C, N, O) and the creation of isoelectronic defects in the boron sublattice (nonstoichiometric $MgB_{y<2}$) are not favorable for superconductivity, and (ii) a possible way of searching for similar MTSC should be via hole doping of $MgB_2$ (i.e., $Mg_{1-x}M_xB_2$ with M=Be, Ca, Li, Na, Cu, Zn) or $CaB_2$ or via creating layered superstructures of the $MgB_2/CaB_2$ type. A recent report of superconductivity in Cu doped $MgB_2$ supports this view.

description: We present a multirotor architecture capable of aggressive autonomous flight and collision-free teleoperation in unstructured, GPS-denied environments. The proposed system enables aggressive and safe autonomous flight around clutter by integrating recent advancements in visual-inertial state estimation and teleoperation. Our teleoperation framework maps user inputs onto smooth and dynamically feasible motion primitives. Collision-free trajectories are ensured by querying a locally consistent map that is incrementally constructed from forward-facing depth observations. Our system enables a non-expert operator to safely navigate a multirotor around obstacles at speeds of 10 m/s. We achieve autonomous flights at speeds exceeding 12 m/s and accelerations exceeding 12 m/s^2 in a series of outdoor field experiments that validate our approach.

description: Real-world laboratories (RwLs) are a form of transdisciplinary research that facilitates learning processes as part of its transformative objectives. Nevertheless, little conceptual effort has been put into the understanding, planning, and evaluation of the learning dimension of RwL work. This paper applies a systematic approach from the discourse on education for sustainable development (ESD) to differentiate three perspectives on the various learning processes occurring in RwLs and exemplifies them with experiences from the RwL Urban Transition Lab 131 in Karlsruhe.

description: Various experimental approaches of transformative research in real-world settings have emerged. Yet, similarities, differences, and specific contributions remain unclear. A characteristic-based comparison reveals complementarities and provides orientation. Real-world laboratories (RwLs, German Reallabore) belong to a family of increasingly popular experimental and transdisciplinary research approaches at the science-society interface. As these approaches in general, and RwLs in particular, often lack clear definitions of key characteristics and their operationalization, we make two contributions in this article. First, we identify five core characteristics of RwLs: contribution to transformation, experimental methods, transdisciplinary research mode, scalability and transferability of results, as well as scientific and societal learning and reflexivity. Second, we compare RwLs to similar research approaches according to the five characteristics. In this way, we provide an orientation on experimental and transdisciplinary research for societal transformations, and reveal the contributions of this type of research in supporting societal change. Our findings enable learning across the different approaches and highlight their complementarities, with a particular focus on RwLs.

 Lesson écrit que Diard et Dussumier ont fait parvenir ces spécimens au MNHN, ce qui correspond aux mentions sur les étiquettes et sous les socles. La mention Eos reticulata correspond à une détermination plus tardive, le nom de borneus étant en effet préoccupé par Psittacus borneus Linnaeus, 1758, actuellement Eos bornea (Linnaeus, 1758). Cette espèce est endémique de l’île de Timorlaut (= Tanimbar) dans les Moluques.

Shakespeare's Fortune: how copyright has failed authors and why it matters

description: A key policy rationale for the system of copyright is to give authors an incentive to create new works. But what if actual financial returns to authors were very poor — so poor that no rational agent could be expected to respond to the incentive? In this thesis I present data from a large sample of Australian films showing that returns are consistently poor even for ‘hit’ films. Data from other countries confirms the finding and there is evidence that returns from other forms of copyright asset such as literary works are also poor. The thesis explores how this situation can have persisted for so longwithout the system breaking down or eliciting strong protests from authors. Drawing on a survey of Australian film producers, I confirm anecdotal evidence that authors are driven by non-financial considerations as well as financial incentives. The Hollywood studios have evolved sophisticated business practices that take advantage of these non-financial motivations. In this they are following the example of London’s booksellers of the early 18th century. Does it matter that authors earn low returns from their copyright assets? Iidentify two classes of author for whom poor returns present a real obstacle to authoring — authors whose work requires independence (such as dissidents) and authors who do not have access to patronage or other forms of subsidy to offset the poor returns from copyright (such as authors from the ‘third world’). Finally, I consider possible reforms to copyright that might improve returns to authors and examine the public policy case for pursuing these reforms.
