description: In this article we establish the unconditional uniqueness of solutions to an Infinite Radial Chern-Simons-Schrödinger (IRCSS) hierarchy in two spatial dimensions. The IRCSS hierarchy is a system of infinitely many coupled PDEs that describes the limiting Chern-Simons-Schrödinger dynamics of infinitely many interacting anyons. The anyons are two dimensional objects which interact through a self-generated field. Due to the interactions with the self-generated field, the IRCSS hierarchy is a system of nonlinear PDEs, which distinguishes it from the linear infinite hierarchies studied previously. Factorized solutions of the IRCSS hierarchy are determined by solutions of the Chern-Simons-Schrödinger system. Our result therefore implies the unconditional uniqueness of solutions to the radial Chern-Simons-Schrödinger system as well.

description: We predict a new candidate high-temperature high-pressure structure of FeSiO$_3$ with space-group symmetry Cmmm by applying an evolutionary algorithm within DFT+U that we call post-perovskite II (PPv-II). An exhaustive search found no other competitive candidate structures with ABO$_3$ composition. We compared the X-ray diffraction (XRD) pattern of FeSiO$_3$ PPv-II with experimental results of the recently reported H-phase of (Fe,Mg)SiO$_3$. The intensities and positions of two main X-ray diffraction peaks of PPv-II FeSiO$_3$ compare well with those of the H-phase. We also calculated the static equation of state, the enthalpy and the bulk modulus of the PPv-II phase and compared it with those of perovskite (Pv) and post-perovskite (PPv) phases of FeSiO$_3$. According to the static DFT+U computations the PPv-II phase of FeSiO$_3$ is less stable than Pv and PPv phases under lower mantle pressure conditions at 0 K and has a higher volume. PPv-II may be entropically stabilized, and may be a stable phase in Earth$'$s lower mantle, coexisting with $α$-PbO$_2$ (Columbite-structured) silica and perovskite, or with magnesiowustite or ferropericlase, depending on bulk composition.

description: Neutrino-induced coherent charged pion production on nuclei, $\stackrel{(-)}ν_μA\toμ^\pmπ^\mp A$ is a rare, inelastic interaction in which a small squared four-momentum $| t|$ is transferred to the recoil nucleus leaving it intact in the reaction. In the scintillator tracker of MINERvA, we remove events with evidence of particles from nuclear breakup and reconstruct $| t|$ from the final state pion and muon. We select low $| t|$ events to isolate a sample rich in coherent candidates. By selecting low $| t|$ events we produce a model-independent measurement of the differential cross section for coherent scattering of neutrinos and anti-neutrinos on carbon. We find poor agreement with the predicted kinematics in neutrino generators used by current oscillation experiments.

description: Secret interactions among sterile neutrinos have been recently proposed as an escape-route to reconcile eV sterile neutrino hints from short-baseline anomalies with cosmological observations. In particular models with coupling g_X \gtrsim 10^{-2} and gauge boson mediators $X$ with $M_X \lesssim 10$ MeV lead to large matter potential suppressing the sterile neutrino production before the neutrino decoupling. With this choice of parameter ranges, big bang nucleosynthesis is left unchanged and gives no bound on the model. However, we show that at lower temperatures when active-sterile oscillations are no longer matter suppressed, sterile neutrinos are still in a collisional regime, due to their secret self-interactions. The interplay between vacuum oscillations and collisions leads to a scattering-induced decoherent production of sterile neutrinos with a fast rate. This process is responsible for a flavor equilibration among the different neutrino species. We explore the effect of this large sterile neutrino population on cosmological observables. We find that a signature of strong secret interactions would be a reduction of the effective number of neutrinos $N_{\rm eff}$ at matter radiation equality down to 2.7. Moreover, for $M_X \gtrsim g_X$ MeV sterile neutrinos would be free-streaming before becoming non-relativistic and they would affect the large-scale structure power spectrum. As a consequence, for this range of parameters we find a tension of a eV mass sterile state with cosmological neutrino mass bounds.

description: Healthy ecosystems and biodiversity are essential for the functioning of our society and economy. The loss of these natural resources reduces our ability to address major challenges such as climate change. Nature-based Solutions (NBS) refers to actions that conserve, manage, and restore natural and modified ecosystems in ways that address these challenges. This term builds on the longstanding recognition of our dependence on nature. The value of NBS is increasingly recognized at all levels, as evidenced by growing commitments and support from countries and organizations worldwide1. The multilaterally agreed definition of NBS, agreed at the May 2022 United Nations Environment Assembly (UNEA)2, by 193 Member States, provides a foundation for a common understanding. The concept is widely used in development and nature-related fields. Globally, there are multiple interventions labelled as NBS and learnings have started to emerge3. Improving our understanding of the opportunities, challenges, trade-offs, and risks associated with NBS is essential for creating successful projects and promoting the global green transition. Understanding the potential for and developing interdisciplinary and transdisciplinary approaches is a key aspect of this process. This project deliverable 1.3 aims to get a better common understanding of how we in the Trans4num project addresses NBS from an inter- and transdisciplinary perspective and how we can develop nested frames and approaches for the interdisciplinary analyses of NBS across sites and scales.

description: As the impact of social media grows, understanding the mechanisms through which social media affects employee behaviour increases. Employing social capital theory, we investigate the mechanisms through which social media usage affects organisational citizenship behaviour (OCB) of faculty in Kenyan private universities. OCB is an important aspect of universities’ performance, given the high level of autonomy in universities. We develop a theoretical model that posits direct links to OCB of three social media usages (social, cognitive, and hedonic) which affect OCB. We also posit indirect links (using autonomy as a mediator) that affect faculty’s intrinsic motivation for OCB. Using descriptive cross-sectional survey, a mediated model was tested on 388 faculty. Results revealed: 1) social media usage significantly impacts OCB, with social and cognitive having a positive relationship, and hedonic having a negative relationship with OCB; 2) social media usage tends to increase autonomy. Findings of this study contribute towards job performance improvement.

description: We have performed quantum Monte Carlo (QMC) simulations and density functional theory (DFT) calculations to study the equations of state of MgSiO$_3$ perovskite (Pv) and post-perovskite (PPv), up to the pressure and temperature conditions of the base of Earth's lower mantle. The ground state energies were derived using QMC and the temperature dependent Helmholtz free energies were calculated within the quasi-harmonic approximation and density functional perturbation theory. The equations of state for both phases of MgSiO$_3$ agree well with experiments, and better than those from generalized gradient approximation (GGA) calculations. The Pv-PPv phase boundary calculated from our QMC equations of states is also consistent with experiments, and better than previous LDA calculations. We discuss the implications for double crossing of the Pv-PPv boundary in the Earth.

description: We use the coupled cluster method to high orders of approximation in order to calculate the ground-state energy, the ground-state magnetic order parameter, and the spin gap of the spin-1/2 J_1-J_2 model on the square lattice. We obtain values for the transition points to the magnetically disordered quantum paramagnetic phase of J_2^{c1}=0.454J_1 and J_2^{c2}= 0.588 J_1. The spin gap is zero in the entire parameter region accessible by our approach, i.e. for J_2 \le 0.49J_1 and J_2 > 0.58J_1. This finding is in favor of a gapless spin-liquid ground state in this parameter regime.

description: The contemporary forestry preoccupation with non-declining even-flow during yield simulations detracts from more important questions about the constraints that should bind the end of a simulation. Whilst long simulations help to convey a sense of sustainability, they are inferior to stronger indicators such as the optimal state and binding conditions at the end of a simulation. Rigorous definitions of sustainability that constrain the terminal state should allow flexibility in the planning horizon and relaxation of non-declining even-flow, allowing both greater economic efficiency and better environmental outcomes. Suitable definitions cannot be divorced from forest type and management objectives, but should embrace concepts that ensure the anticipated value of the next harvest, the continuity of growing stock, and in the case of uneven-aged management, the adequacy of regeneration.

description: Steels are commonly used in high-performance demanding applications due to their favourable mechanical properties. Various surface engineering techniques have been developed for steels, among which chromizing is an affordable high-throughput case-hardenig process for improved surface hardness and wear resistance while retaining the substrate ductility and toughness. In this work, tribological testing along with nano- and micro-indentation and morphological and composional characterisation were used to understand the effects of the chromizing process on the AISI 1095 carbon steel, 52100 bearing steel and A2, D2 and M2 tool steels. The results of this study demonstrate that the chromizing treatment of low-cost 1095 and 52100 steels significantly improves their wear and hardness properties to a level comparable to the more costly tool steels. While chromizing also increased the hardness of the tool steels, it had little improvement on the wear resistance for the D2 and M2 tool steels.

description: Comparing electronic Hydrogen with muonic Hydrogen shows that the discrepancy in measurement of the Lamb shift in the both systems are relatively of order of $(\frac{m_μ}{m_e})^{4-5}$. We explore the spectrum of Hydrogen atom in noncommutative $QED$ to compare the noncommutative effects on the both bound states. We show that in the Lorentz violating noncommutative QED the ratio of NC-corrections is $(\frac{m_μ}{m_e})^3$ while in the Lorentz conserving NCQED is $(\frac{m_μ}{m_e})^5$. An uncertainty about $1 \,Hz\ll 3\,kHz$ in the Lamb shift of Hydrogen atom leads to an NC correction about $10 \,MHz$ in the Lorentz violating noncommutative QED and about $400 \,GHz$ in the Lorentz conserving noncommutative QED.

description: Strong singly-ionized magnesium (MgII) absorption lines in quasar spectra typically serve as a proxy for intervening galaxies along the line of sight. Previous studies have found a correlation between the number of these MgII absorbers and the Faraday rotation measure (RM) at $\approx5$ GHz. We cross-match a sample of 35,752 optically-identified non-intrinsic MgII absorption systems with 25,649 polarized background radio sources for which we have measurements of both the spectral index and RM at 1.4 GHz. We use the spectral index to split the resulting sample of 599 sources into flat-spectrum and steep-spectrum subsamples. We find that our flat-spectrum sample shows significant ($\sim3.5σ$) evidence for a correlation between MgII absorption and RM at 1.4 GHz, while our steep-spectrum sample shows no such correlation. We argue that such an effect cannot be explained by either luminosity or other observational effects, by evolution in another confounding variable, by wavelength-dependent polarization structure in an active galactic nucleus, by the Galactic foreground, by cosmological expansion, or by partial coverage models. We conclude that our data are most consistent with intervenors directly contributing to the Faraday rotation along the line of sight, and that the intervening systems must therefore have coherent magnetic fields of substantial strength ($\bar{B}=1.8\pm0.4$ $μ$G). Nevertheless, the weak nature of the correlation will require future high-resolution and broadband radio observations in order to place it on a much firmer statistical footing.

description: Multipartite nonlocality is of great fundamental interest and constitutes a useful resource for many quantum information protocols. However, demonstrating it in practice, by violating a Bell inequality, can be difficult. In particular, standard experimental setups require the alignment of distant parties' reference frames, which can be challenging or impossible in practice. In this work we study the violation of certain Bell inequalities, namely the Mermin, Mermin-Klyshko and Svetlichny inequalities, without shared reference frames, when parties share a Greenberger-Horne-Zeilinger (GHZ) state. Furthermore, we analyse how these violations demonstrate genuine multipartite features of entanglement and nonlocality. For 3, 4 and 5 parties, we show that it is possible to violate these inequalities with high probability, when the parties choose their measurements from the three Pauli operators, defined only with respect to their local frames. Moreover, the probability of violation, and the amount of violation, are increased when each party chooses their measurements from the four operators describing the vertices of a tetrahedron. We also consider how many randomly chosen measurement directions are needed to violate the Bell inequalities with high probability. We see that the obtained levels of violation are sufficient to also demonstrate genuine multipartite entanglement and nonseparability. Finally, we show analytically that choosing from two measurement settings per party is sufficient to demonstrate the maximum degree of genuine multipartite entanglement and nonseparability with certainty when the parties' reference frames are aligned in one direction so that they differ only in rotations around one axis.

description: In the present study, the molecular-dynamics method was used to investigate into the effect of atomic mass on the detonation wave processes in molecular crystals. The characteristics of interest were the detonation-wave propagation velocity, the detonation-wave structure, the delay time of the chemical reaction, and macroscopic energy characteristics of the disturbed region. A comparison of gained molecular-dynamics data with the predictions of the continual theory of detonation is given; in particular, the Chapman-Jouguet condition is addressed.

description: The entropy of a monomer-dimer system on an infinite bipartite lattice can be written as a mean-field part plus a series expansion in the dimer density. In a previous paper it has been conjectured that all coefficients of this series are positive. Analogously on a connected regular graph with $v$ vertices, the "entropy" of the graph ${\rm ln} N(i)/v$, where $N(i)$ is the number of ways of setting down $i$ dimers on the graph, can be written as a part depending only on the number of the dimer configurations over the completed graph plus a Newton series in the dimer density on the graph. In this paper, we investigate for which connected regular graphs all the coefficients of the Newton series are positive (for short, these graphs will be called positive). In the class of connected regular bipartite graphs, up to $v=20$, the only non positive graphs have vertices of degree $3$. From $v=14$ to $v=30$, the frequency of the positivity violations in the $3$-regular graphs decreases with increasing $v$. In the case of connected $4$-regular bipartite graphs, the first violations occur in two out of the $2806490$ graphs with $v=22$. We conjecture that for each degree $r$ the frequency of the violations, in the class of the $r-$regular bipartite graphs, goes to zero as $v$ tends to infinity. This graph-positivity property can be extended to non-regular or non-bipartite graphs. We have examined a large number of rectangular grids of size $N_x \times N_y $ both with open and periodic boundary conditions. We have observed positivity violations only for $min(N_x, N_y) = 3$ or $4$.

description: Wireless sensor networks have become more trendy in the domains like environmental sensing, health
monitoring, home and building automation, elegant energy, green computing, etc. The application of
wireless sensor networks can be extended for the effective monitoring of the data center environment.
Almost all the data centres are equipped with high end servers, data storage equipments which must be
protected against cooling failures by providing necessary monitoring tools and alerting mechanism to the
administrators. It is therefore very essential to design a system that monitors and alerts about the
environmental conditions of the data centres. The job carried out to design an effective information centre
monitoring organism has been discussed in this document. This paper discusses both hardware and
software development aspects to achieve the desired goal. The wireless personal area network has been
established in the data centres using low power wireless sensor motes which are powered by Zig bee
protocol and Zigbee to internet gateway system. This will enable the monitoring of data centre
environmental parameters such as temperature and the relative humidity over the internet. This organism
also has a SMS/e-mail based alerting provision whenever the sensed parameters go beyond the preset
threshold ideals.

description: Statistically based phenomenology of mesodefects allowed the interpretation of damage kinetics as the scaling transitions in defect ensembles and the explanation of limited steady-state crack velocity, transition to the branching regime, scaling aspects of dynamic and fatigue failure. Qualitative different nonlinearity for damage kinetic equation was established for the slip bands and microcrack controlled stages of fatigue failure. This allows the original interpretation of the 4th Paris law in the terms of scaling universality and the explanation of the crack closure effect as the consequence of the anomalous energy absorbtion at the crack tip zone during scaling transitions in mesodefects ensemble. Presented results reflect the long-term collaboration of research teams of the Laboratory of Physical Foundation of Strength of the Institute of Continuous Media Mechanics of RAS (Russia) and LAMEFIP ENSAM of the Bordeaux University (France).

description: We extend the coupled-wire construction of quantum Hall phases, and search for fractional topological insulating states in models of weakly coupled wires at zero external magnetic field. Focussing on systems beyond double copies of fractional quantum Hall states at opposite fields, we find that spin-spin interactions can stabilize a large family of fractional topological phases with broken time reversal invariance. The latter is manifest by spontaneous spin polarization, by a finite Hall conductivity, or by both. This suggests the possibility that fractional topological insulators may be unstable to spontaneous symmetry breaking.

description: "For two decades after the courts struck down the Communications Decency Act in 1997, direct government regulation of the internet was a political third rail. That era of digital salutary neglect arguably contributed to American dominance in consumer software applications; if software has eaten the world, to extend Marc Andreessen’s metaphor, the all-you-can-eat buffet line started in the United States. As a result, U.S. tech hubs have been the destination for global capital and skilled immigrants, mitigating the economic effects of the Great Stagnation as the manufacturing industry moved overseas. Recently, however, there has been growing support for internet regulation. Remarkably for an era of heightened political polarization, representatives of both major U.S. parties have called for antitrust action against big tech companies. These critics argue that the companies’ market dominance leads to excessive political influence and poor outcomes for consumers. This paper does not address these antitrust issues. Instead we examine another plausible regulatory response to market domination: public oversight of private companies according to a public interest standard. The prospect of a new era of public interest oversight should not be dismissed out of hand. Multiple politicians from both parties have called for the federal government to take an active role in fighting various online social ills, including hate speech, gun-related content, political bias, and sexual trafficking. In theory, public interest regulation could address these ills while also dealing with market power. In practice, public interest regulation could very well fail to accomplish those goals while creating negative unintended consequences. The first section of this essay explores the growing interest in cross-applying the public interest standard from broadcasting to the internet. The second section recounts the history of the standard and the problems it created for free speech. The third section considers the implications of our historical analysis for public and private policymaking going forward."

description: Abstract

Salinity is a significant limitation to agricultural crop productivity worldwide, with varying responses observed among different plant species and cultivars. To address this issue, a study was conducted to identify salt-tolerant rootstocks for watermelon grafting. Several experiments were carried out to select the suitable grafting technique used for grafting of watermelon. In the experiment, effect of 2 salinity levels (control and 9 dS m-1 of NaCl) was investigated on the basis of growth, physio-morphological and biochemical attributes of salt tolerant rootstocks (Kalash, Crystal Long, Green Round and Desi Bittergourd) and two grafting techniques (hole insertion and splice grafting) were used for improvement of watermelon cultivar (Augusta). Rootstock and scion cultivars seeds were grown in plastic pots, using fine sand as growth medium. Half strength of Hoagland solution was applied to plants as nutrition. The grafted plants were treated with two different concentrations of NaCl. Symptom scoring was conducted, and subsequent measurements included number of leaves, root length, stem length, and diameter per plant, dry matter production was considered. Data of various morphological, physiological and biochemical parameters were collected and analyzed statistically using standard statistical procedures. The study revealed that Crystal Long variety of bottle gourd was salt tolerant and performed better when watermelon is grafted on it.
Energy-based Analysis of Biochemical Cycles using Bond Graphs

description: Thermodynamic aspects of chemical reactions have a long history in the Physical Chemistry literature. In particular, biochemical cycles - the building-blocks of biochemical systems - require a source of energy to function. However, although fundamental, the role of chemical potential and Gibb's free energy in the analysis of biochemical systems is often overlooked leading to models which are physically impossible. The bond graph approach was developed for modelling engineering systems where energy generation, storage and transmission are fundamental. The method focuses on how power flows between components and how energy is stored, transmitted or dissipated within components. Based on early ideas of network thermodynamics, we have applied this approach to biochemical systems to generate models which automatically obey the laws of thermodynamics. We illustrate the method with examples of biochemical cycles. We have found that thermodynamically compliant models of simple biochemical cycles can easily be developed using this approach. In particular, both stoichiometric information and simulation models can be developed directly from the bond graph. Furthermore, model reduction and approximation while retaining structural and thermodynamic properties is facilitated. Because the bond graph approach is also modular and scaleable, we believe that it provides a secure foundation for building thermodynamically compliant models of large biochemical networks.

description: Сейсмичность Алтае-Саянской горной области анализируется совместно с рельефом местности и активными разломами. Обнаружено, что наиболее тектонически активные структуры проявляют себя в сейсмичности за год и их сейсмичность является устойчивой из года в год. Наблюдается иерархия в геологических структурах по скорости проявления в сейсмичности. Крупнейшие землетрясения региона приурочены к некоторым из структур, активным по землетрясениям малых энергий. В сейсмическом режиме выделяются фоновая сейсмичность и сейсмичность активизации. Фоновая сейсмичность, на первый взгляд хаотичная, с течением времени упорядочивается в соответствии с блочной структурой Алтае-Саянской горной области. Сочетание приподнятых горных массивов и впадин создает ячеистую структуру, которая оказывает упорядоченное сопротивление коллизионному воздействию со стороны Джунгарской впадины. Фоновая сейсмичность концентрируется, в основном, в горном обрамлении впадин. Сейсмические активизации рассматриваются как нестационарный режим той или иной геологической структуры. Активизации тесно связаны с крупнейшими землетрясениями и в большей своей части протекают как афтершоковый процесс. Крупные активизации структур Алтая и Саян индивидуальны по сценарию своего развития. Ярко самобытный характер имеет активизация, возникшая при Бусингольском землетрясении 27.12.1991 г. (М = 6.5) и продолжающаяся по сей день. Событие приурочено к границе Алтае-Саянской области с Байкальской рифтовой зоной, где коллизионные процессы давят на впадину, а рифтовые стремятся ее раздвинуть. В противоборстве двух сил возникла пульсирующая и длительная сейсмическая активизация
Computing the Tutte Polynomial of a Matroid from its Lattice of Cyclic Flats

description: We show how the Tutte polynomial of a matroid $M$ can be computed from its condensed configuration, which is a statistic of its lattice of cyclic flats. The results imply that the Tutte polynomial of $M$ is already determined by the abstract lattice of its cyclic flats together with their cardinalities and ranks. They furthermore generalize a similiar statement for perfect matroid designs due to Mphako and help to understand families of matroids with identical Tutte polynomial as constructed by Ken Shoda.

description: Working with explicit examples given by the 56 representation in $SU(8)$, and the 10 representation in $SU(5)$, we show that symmetry breaking of a group ${\cal G}\supset {\cal G}_1 \times {\cal G}_2$ by a scalar in a rank three or two antisymmetric tensor representation leads to a number of distinct $modular$ ground states. For these broken symmetry phases, the ground state is periodic in an integer divisor $p$ of $N$, where $N>0$ is the absolute value of the nonzero $U(1)$ generator of the scalar component $Φ$ that is a singlet under the simple subgroups ${\cal G}_1$ and ${\cal G}_2$. Ground state expectations of fractional powers $Φ^{p/N}$ provide order parameters that distinguish the different phases. For the case of period $p=1$, this reduces to the usual Higgs mechanism, but for divisors $N\geq p>1$ of $N$ it leads to a modular ground state with periodicity $p$, implementing a discrete Abelian symmetry group $U(1)/Z_p$. This observation may allow new approaches to grand unification and family unification.
