description: In the Human Resources domain the accurate matching between job positions and job applicants profiles is crucial for job seekers and recruiters. The use of recruitment taxonomies has proven to be of significant advantage in the area by enabling semantic matching and reasoning. Hence, the development of Knowledge Bases (KB) where curricula vitae and job offers can be uploaded and queried in order to obtain the best matches by both, applicants and recruiters is highly important. We introduce an approach to improve matching of profiles, starting by expressing jobs and applicants profiles by filters representing skills and competencies. Filters are used to calculate the similarity between concepts in the subsumption hierarchy of a KB. This is enhanced by adding weights and aggregates on filters. Moreover, we present an approach to evaluate over-qualification and introduce blow-up operators that transform certain role relations such that matching of filters can be applied.

description: In quasi single field inflation there are massive fields that interact with the inflaton field. If these other fields are not much heavier than the Hubble constant during inflation ($H$) these interactions can lead to important consequences for the cosmological energy density perturbations. The simplest model of this type has a real scalar inflaton field that interacts with another real scalar $S$ (with mass $m$). In this model there is a mixing term of the form $μ{\dot π} S$, where $π$ is the Goldstone fluctuation that is associated with the breaking of time translation invariance by the time evolution of the inflaton field during the inflationary era. In this paper we study this model in the region $(μ/H )^2 +(m/H)^2 >9/4$ and $m/H \sim {\cal O}(1)$ or less. For a large part of the parameter space in this region standard perturbative methods are not applicable. Using numerical and analytic methods we derive a number of new results. In addition we study how large $μ/H$ has to be for the large $μ/H$ effective field theory approach to be applicable.

description: This study determined the background occurrence, distribution, and exposure risks of the sixteen priority polycyclic aromatic hydrocarbons (16-PAHs) in soils from the vicinity of petroleum tank farms in Western Delta, Nigeria. The samples were collected in the fifteen petroleum tank farms at 0–15 cm, 15–30 cm, and 30–45 cm depths. After extraction by ultrasonication with n-hexane/dichloromethane and clean-up in silica gel/alumina packed column. The concentration of PAHs was determined using gas chromatography fitted with mass spectrometry (GC–MS). The Σ16-PAHs ranged from 4.49 to 447.86 mg kg-1 for all sites and depths. The concentration of the Σ16-PAHs in the samples exceeded the Department of Petroleum Resources (DPR) target values, and 38% depicts PAHs concentrations above the DPR intervention values, this suggests the presence of high molecular weight petroleum products such as diesel and heavy oil, and soils from the tank farms' are polluted with a considerable amount of soils within PAHs. The total cancer risk falls within the low to moderate category. The principal sources of PAHs are petrogenic and low-high-temperature combustion processes. This study provided empirical data on the pollution load, origin, and associated risks of PAHs in soils in some petroleum tank farms. Appropriate clean-up actions are needed to mitigate the accumulation of PAHs in soil and biota and the ecological and human exposure risks in the surrounding aquatic and terrestrial environments.

description: In this study, 16 polycyclic aromatic hydrocarbons (PAHs) optimally controlled by the U.S. Environmental Protection Agency (EPA) were investigated. Three representative coal-fired power plants were selected as the research areas in Bijie, Guizhou Province, and 24 soil samples were collected totally from power plants at different depths and at different distances from the point pollution sources (plants). The physicochemical properties and microbial characteristics of the soil from the three power plants were also studied. The results showed that 16 PAHs were detected in all soils of the three power plants, with total concentrations ranging from 0.2 to 12.2 mg kg−1, and that PAHs in the soils were mainly 2, 3 rings with percentages ranging from 42% to 82%. The proportions of low molecular weight (LMW) PAHs were higher near the contaminated plants. Moreover, since they were easily dispersed further away with atmospheric transfer, the proportions of lighter LMW PAHs were also higher far from the point source, while the proportions of heavier high molecular weight (HMW) PAHs were higher at some distance from the point source. In addition, the distribution patterns of PAHs in the soil at different depths were slightly different because the microbial activity in the surface soil at each sampling site was greater than that in the deeper soil, and the leaching behavior of each compound was different. Finally, based on the principal component analysis (PCA) method, coal combustion is not the only source of PAHs in soils from power plants, and vehicle emissions cannot be negligible.

description:          Fisheries is one of the leading food sectors in the world. Most of the people getting benefited trough fishing Worldwide. But now a days oceans are facing some dangerous treats like Ghost fishing, plastic pollution and others. The abandoned, lost and discarded [ALD] fishing gears in the oceans will continuously active and fish both targeted and non- targeted fish stocks for many years leads to ghost fishing through ghost gears.

          The majority of the Fishing gears up to Early 1960s were constructed of natural fibres like Cotton, Jute, Manila, Hemp, Sisal etc. Later due to increase of awareness on fishing and also benefits of having fish. People found more sophisticated ways to increase fishing. That made the invention of synthetic fibres like Nylon [Poly amide], Poly ethylene, Poly ester etc. Having more catchability, duration, and, strength than that of natural fibres. Many types of gears were invented Gill nets, set gill nets, Trammel nets, Drift nets etc. by using these synthetic fibres Continuous fishing with these gears will cause the problem of Ghost fishing due to wear and tear or by any other unexpected loss of gears, it leads to damage of the marine environment along with marine species.

description: Ecopath International Initiative Research Organization (EII) has been commissioned to conceptualize the integration of the Ecopath with Ecosim (EwE) food web modelling approach into the Marine Spatial Planning (MSP) Challenge 2050 software.

The MSP Challenge 2050 serious game is an immersive, three-dimensional software system that educates stakeholders, planners and the general public about trade-offs and environmental consequences of planning decisions in the marine and coastal ecosystem over space and time (Stolte et al., 2013). The ecology component in the MSP software is a simplification of a EwE model of the North Sea based on Mackinson and Daskalov (2007). This food web model was recently reviewed and was deemed unsuitable to deliver useful ecological predictions, even for game purposes
(Steenbeek, 2015). Rather than fixing identified shortcomings in the MSP software, it has been decided to replace the MSP ecology calculations with a direct link to EwE.

This document provides the conceptual design of this linkage from the EwE point of view. A brief overview of EwE and its internal structure is given. Capabilities of EwE to
incorporate MSP player input into its food web dynamics, and the mechanisms to provide game feedback back to MSP, are identified. The essential data flow to and from EwE is explained, and a conceptual communication protocol between MSP and EwE is provided
Another resolution of the configurational entropy paradox as applied to hard spheres

description: Recently, Ozawa and Berthier [J. Chem. Phys., 2017, 146, 014502] studied the configurational and vibrational entropies $S_c$ and $S_v$ from the relation $S_{tot}=S_c+S_v$ for polydisperse mixtures of spheres. They noticed that because $S_{tot}/N$ shall contain the mixing entropy per particle $k_B s_m$ and $S_v/N$ shall not, the configurational entropy per particle $S_c/N$ shall diverge in the thermodynamic limit for continuous polydispersity due to the diverging $s_m$. They also provided a resolution for this paradox and related problems-it relies on a careful redefining of $S_c$ and $S_v$. Here, we note that the relation $S_{tot}=S_c+S_v$ is essentially a geometric relation in the phase space and shall hold without redefining $S_c$ and $S_v$. We also note that the total entropy per particle $S_{tot}/N$ diverges with $N \to \infty$ with continuous polydispersity as well. The usual way to avoid this and other difficulties with $S_{tot}/N$ is to work with the excess entropy $ΔS_{tot}$ (relative to the ideal gas of the same polydispersity). Speedy [Mol. Phys., 1998, 95, 169] applied this approach to the relation above and wrote this relation as $ΔS_{tot}=S_c+ΔS_v$. This form has flows as well, because $S_v/N$ does not contain the $k_B s_m$ term and the latter is introduced into $ΔS_v/N$ instead. Here, we suggest that this relation shall actually be written as $ΔS_{tot}=Δ_c S_c+Δ_v S_v$, where $Δ=Δ_c+Δ_v$ while $Δ_c S_c=S_c-k_B N s_m$ and $Δ_v S_v=S_v-k_B N[1+\ln(V/Λ^d N)+U/N k_B T]$ with $Λ$ standing for the de Broglie wavelength. In this form, all the terms per particle are always finite for $N \to \infty$ and continuous when introducing a small polydispersity to a monodisperse system. We also suggest that the Adam-Gibbs and related relations shall in fact contain $Δ_c S_c/N$ instead of $S_c/N$.

description: The electrophilicity of the functional groups of β-aroylpropionic acid 3 was utilized as a key starting material through the reaction with different nitrogen nucleophiles to synthesize novel various pyridazin-3(2H)-one derivatives as well as some condensed acyclic compounds. The chemical structures of the synthesized compounds were characterized by IR, 1H NMR, 13C NMR, and mass spectra beside elemental analysis. The antifungal activity of the synthesized compounds against three types of fungus namely, Fusarium solani, Alternaria solani, and Fusarium semitectum realized that β-aroylpropionic acid 3, thiosemicarbazone derivative 8, and N-cyanoacetyl dihydropyridazinone derivative 17 displayed spectacular results for antifungal study and are worth being further evaluated in vivo and in the field.
Computationally Efficient Nonlinear Bell Inequalities for General Quantum Networks

Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The correlations in quantum networks have attracted strong interest with new types of violations of the locality. The standard Bell inequalities cannot characterize the multipartite correlations that are generated by multiple sources. The main problem is that no computationally efficient method is available for constructing useful Bell inequalities for general quantum networks. In this work, we show a significant improvement by presenting new, explicit Bell-type inequalities for general networks including cyclic networks. These nonlinear inequalities are related to the matching problem of an equivalent unweighted bipartite graph that allows constructing a polynomial-time algorithm. For the quantum resources consisting of bipartite entangled pure states and generalized Greenberger-Horne-Zeilinger (GHZ) states, we prove the generic non-multilocality of quantum networks with multiple independent observers using new Bell inequalities. The violations are maximal with respect to the presented Tsirelson's bound for Einstein-Podolsky-Rosen (EPR) states and GHZ states. Moreover, these violations hold for Werner states or some general noisy states. Our results suggest that the presented Bell inequalities can be used to characterize experimental quantum networks.

description: We study the symmetry energy and the core-crust transition in neutron stars using the finite-range Gogny nuclear interaction and examine the deduced crustal thickness and crustal moment of inertia. We start by analyzing the second-, fourth- and sixth-order coefficients of the Taylor expansion of the energy per particle in powers of the isospin asymmetry for Gogny forces. These coefficients provide information about the departure of the symmetry energy from the widely used parabolic law. The neutron star core-crust transition is evaluated by looking at the onset of thermodynamical instability of the liquid core. The calculation is performed with the exact (i.e., without Taylor expansion) Gogny EoS for the core, and also with its Taylor expansion in order to assess the influence of isospin expansions on locating the inner edge of neutron star crusts. It is found that the properties of the core-crust transition derived from the exact EoS differ from the predictions of the Taylor expansion even when the expansion is carried through sixth order in the isospin asymmetry. Gogny forces, using the exact EoS, predict the ranges $0.094 \text{ fm}^{-3} \lesssim ρ_t \lesssim 0.118\text{ fm}^{-3}$ for the transition density and $0.339 \text{ MeV fm}^{-3} \lesssim P_t \lesssim 0.665 \text{ MeV fm}^{-3}$ for the transition pressure. The transition densities show an anticorrelation with the slope parameter $L$ of the symmetry energy. The transition pressures are not found to correlate with $L$. Neutron stars obtained with Gogny forces have maximum masses below $1.74M_\odot$ and relatively small moments of inertia. The crustal mass and moment of inertia are evaluated and comparisons are made with the constraints from observed glitches in pulsars.

description: In this research paper, an eco-friendly extraction process of dyes from Vicia faba L. membranes was developed. In this regard, the influence of independent process factors like the weight of material, the extraction time, the temperature and the sodium hydroxide concentration on the natural dye extraction from Vicia faba membranes was investigated. The optimisation of the extraction conditions and the effect evaluation of the different operating parameters were carried out using a Box–Behnken design under response surface methodology. The optimum conditions were found to be 66 °C, 90 min, 5 g and 0.1628 mol·L−1 for extraction temperature, time, mass of the material and sodium hydroxide concentration, respectively. The efficiency of this extraction process under these optimum conditions was evaluated by measuring the total phenolic content (TPC), the total flavonoid content and the relative colour yield (K/S). In these operating conditions, good fastness ratios were observed for the dyed fabrics.
A aventura incessante de Ulisses: Kazantzakis e José Miguel Silva

description: Largamente retomado pela tradição literária, o tema da viagem de Ulisses em muitas de suas representações confi rma o ideal do herói nostálgico que se dirige ao lar em cumprimento de seu nóstos, assim como, em outras, reafi rma o ímpeto do eterno navegador de mares. Nikos Kazantzakis retoma o Ulisses lendário, insatisfeito com o retorno ao lar, construindo a partir dele o seu protótipo de herói e dando forma, em plena modernidade, ao poema épico Odisséia: uma continuação moderna (1938). A partir do canto XXII, verso 477 do poema de Homero, Ulisses é levado a um novo itinerário abandonando Ítaca defi nitivamente. Embora se baseie em Homero, recuperando as personagens e a antiga estrutura épica, Kazantzakis não se afasta de seu tempo, compondo um novo Ulisses representante do mundo moderno, próximo das fi losofi as de Nietzsche e Bergson, bem como do budismo. Como fi gura «entre mundos», o Ulisses de Kazantzakis recupera as antigas delineações de Homero e igualmente incorpora as questões da modernidade – o niilismo, a desesperança, a multiplicidade. Contemporaneamente, José Miguel Silva encontra no mesmo tema da Odisséia homérica a matéria e a forma para compor Ulisses já não mora aqui. É pelo confronto da semelhança temática e das diferenças de composição entre as obras do poeta grego moderno e do poeta português que este artigo se constitui.

description: We propose a new genetic algorithm with optimal recombination for the asymmetric instances of travelling salesman problem. The algorithm incorporates several new features that contribute to its effectiveness: (i) Optimal recombination problem is solved within crossover operator. (ii) A new mutation operator performs a random jump within 3-opt or 4-opt neighborhood. (iii) Greedy constructive heuristic of W.Zhang and 3-opt local search heuristic are used to generate the initial population. A computational experiment on TSPLIB instances shows that the proposed algorithm yields competitive results to other well-known memetic algorithms for asymmetric travelling salesman problem.

description: Astrocytic tumour cells derived from human (GL-15) and rat (C6) gliomas, as well as non-tumoural astrocytic cells, were exposed to the saponin-rich fraction (SF) from Agave sisalana waste and the cytotoxic effects were evaluated. Cytotoxicity assays revealed a reduction of cell viability that was more intensive in glioma than in non-tumoural cells. The SF induced morphological changes in C6 cells. They were characterised by cytoplasmic vacuole formation associated with increase in the formation of acidic lysosomes. The SF was subjected to purification on Sephadex LH-20, which characterised three probable steroidal saponins (sisalins) by electrospray ionisation mass spectrometry multistage (ESI-MSn). Sisalins from sisal may be responsible for the cytotoxicity, which involves cytoplasmatic vacuole formation and selective action for glioma cells.

description: Το βιβλίο απευθύνεται σε προπτυχιακούς φοιτητές Ελληνικών Πανεπιστημίων οι οποίοι διδάσκονται ένα βασικό μάθημα Άλγεβρας. Το βιβλίο είναι συνοδευτικό ενός τυπικού συγγράματος Βασικής Άλγεβρας προπτυχιακού επιπέδου και σκοπός του είναι να βοηθήσει τον αναγνώστη, μέσω αναλυτικής επίλυσης ασκήσεων διάφορων επιπέδων δυσκολίας, θεματικής και περιεχομένου, να κατανοήσει τις θεμελιώδεις αρχές, τις τεχνικές, και μεθόδους της βασικής Άλγεβρας.

Το βιβλίο αφορά κυρίως φοιτητές τμημάτων Μαθηματικών (αλλά και παρεμφερών τμημάτων) Ελληνικών Πανεπιστημίων. Στο βιβλίο δεν προαπαιτούνται παρά μόνο στοιχειώδεις γνώσεις από άλλα μαθήματα οι οποίες αναλύονται συνοπτικά, και έτσι το βιβλίο επίσης μπορεί να αποτελέσει βοήθημα για την κατανόηση των θεμελιωδών αρχών, τεχνικών και μεθόδων της Βασικής Άλγεβρας και από μη εξειδικευμένους αναγνώστες. Έτσι μπορεί να χρησιμοποιηθεί από διδάσκοντες, φοιτητές, επαγγελματίες της περιοχής (καθηγητές), και γενικά από ενδιαφερόμενους να κατανοήσουν τις βασικές αρχές της θεωρίας ομάδων και δακτυλίων.

Το κύριο μέρος του βιβλίου είναι αφιερωμένο στη αναλυτική επίλυση ασκήσεων οι οποίες αφορούν δύο εκ των βασικότερων δομών της σύγχρονης Άλγεβρας, της δομής ομάδας και της δομής δακτυλίου, καθώς και των εφαρμογών τους. Το βιβλίο χωρίζεται σε δύο μέρη (θεωρία ομάδων και θεωρία δακτυλίων) και σε 14 Κεφάλαια. Σε κάθε Κεφάλαιο του βιβλίου αναπτύσσεται χωρίς αποδείξεις συνοπτική θεωρία η οποία και χρησιμοποιείται για την επίλυση των ασκήσεων. Στη συνέχεια επιλύονται αναλυτικά ασκήσεις, σε διάφορα επίπεδα (ασκήσεις κατανόησης, υπολογιστικές ασκήσεις, θεωρητικές ασκήσεις, ασκήσεις οι οποίες επεκτείνουν γνωστά αποτελέσματα, κτλ), οι οποίες αφορούν την εκτεθείσα συνοπτική θεωρία. Κάποιες από τις ασκήσεις συνοδεύονται από σχόλια, όπου αναδεικνύεται η σχέση τους με άλλες ασκήσεις, με αντίστοιχα θεωρητικά θέματα ή επεκτάσεις αυτών, ή με αναφορές στη βιβλιογραφία. Τέλος σε κάθε Κεφάλαιο προτείνεται προς λύση σειρά ασκήσεων.

description: A set of novel N-methylspiropyrrolidine hybrids have been synthesized regio selectively employing 1,3-dipolar cycloaddition reaction of substituted chalcones with azomethine ylides (work up in situ from isatin and sarcosine). The spiropyrrolidines structures were studied using FT-IR, 1H and 13C NMR spectroscopic data, and was finally confirmed by X-ray diffraction study. Hirshfeld surface analysis was correlated with X-ray diffraction and described different intermolecular contacts. Good antibacterial activity was reported against gram-positive and gram-negative bacterial strains of Bacillus subtillis, Enterococcus faecalis, E. coli, and Pseudomonas aeruginosa. Initially, antibacterial activity of compounds was confirmed by the zone of inhibition. Most of the compounds have shown MIC and MBC in the range between 50-200 µg∕mL against both types of bacteria. Further, for mechanism of action, the tested compounds were checked for the inhibition of an established bacterial drug target, DNA gyrase using in silico approaches.

description: Alkyl/aralkyl/phenacyl thiotriazolyl isoindoline-1,3-diones were synthesized by the reaction of dipotassium cyanodithioimidocarbonate salt with hydrazine hydrate, phthalic anhydride and alkyl/aralkyl/phenacyl bromides using acetic acid and sodium acetate via a one-pot four-component synthesis. Alternatively, the same final products were also synthesized by the reaction of dipotassium cyanodithioimidocarbonate salt with hydrazine hydrate in presence of acetic acid to give intermediate 5-amino-4H-1,2,4-triazole-3-thiol [I]. This compound was further reacted with phthalic anhydride, followed by a reaction with alkyl/aralkyl/phenacyl bromides to give the title compounds in a two-step process. In this method, the yields are less compared to one-pot four-component synthesis. All the newly synthesized compounds were characterized by their spectral studies (FTIR, 1H-NMR, 13C-NMR, Mass). Further, the synthesized compounds were screened for their in-vitro anticancer activity. Compounds 5 m, 5p, 5r showed good cytotoxic assay against Hela cancer cell lines. Furthermore, compounds 5(a-t) were subjected to their docking analysis and DFT calculations.

description: The Quark-Hadron Chiral Parity-Doublet model (Q$χ$P) is applied to calculate compact star properties in the presence of a deconfinement phase transition. Within this model, a consistent description of nuclear matter properties, chiral symmetry restoration, and a transition from hadronic to quark and gluonic degrees of freedom is possible within one unified approach. We find that the equation of state obtained is consistent with recent perturbative quantum chromodynamics (QCD) results and is able to accommodate observational constraints of massive and small neutron stars. Furthermore, we show that important features of the equation of state, such as the symmetry energy and its slope, are well within their observational constraints.

description: As previously reported, we have synthesized an azo azomethine ligand 4-((E)-(2,5 dichloro phenyl) diazenyl)−2-((E)-((4-hydroxyphenyl) imine) methyl) phenol (L). The synthesized ligand has been used to prepare copper(II), nickel(II), and cobalt(II) metal complexes and characterized using various analysis techniques. To identify complexes, methods, such as elemental analyses, electrical conductivity, IR spectroscopy, mass spectrometry, magnetic moment, vibrating sample magnetometry (VSM), 1HNMR, UV–Vis, and thermal analysis were utilized, and a mononuclear structure was proposed for all compounds and all the complexes are non-electrolytes in nature. The chelation of the ligands to the metal ions occurs through phenolic oxygen and nitrogen atoms of the azomethine group of the ligands. According to various analytical and spectral data, a square planar structure is proposed for copper and nickel metal complexes and a quadrilateral structure is proposed for cobalt complexes. The antibacterial properties of ligands and complexes of copper(II), nickel(II), and cobalt(II) were investigated in vitro on standard bacteria as well as on bacteria isolated from clinical specimens (urine). The results revealed that the ligand and its metal complexes had a very high antibacterial activity against Staphylococcus aureus, but were ineffective against other studied bacteria. The synergistic effect of the compounds with the three antibiotics (vancomycin (V), methicillin (M), and trimethoprim (T)) was also investigated, along with the cytotoxicity of its ligand and copper complex in HFF cell line. At a concentration of 3.90 μl of these compounds, cell viability was significant. The structure of ligand and complexes was optimized by DFT calculations. Computational methods were performed for deeper understanding of the interaction between ligands and metal by EDA calculations. This result confirmed that the bonding between ligands to metal was mainly covalent. The complexes investigated are reported for the first time. The search for new antimicrobial agents against Staphylococcus aureus is an urgent medical need. Therefore, sensitive and selective diagnosis of this pathogenic bacterium is of great importance, which has been obtained in this study. The compounds synthesized from among the nine gram-negative and gram-positive bacteria are only sensitive to Staphylococcus aureus bacteria.

description: Quantum interface links stationary qubits in quantum memory with flying photonic qubits in optical transmission channels and constitutes a critical element for future quantum internet. Entanglement of quantum interfaces is a key step for realization of quantum networks. Through heralded detection of photon interference, here we generate multipartite entanglement between 25 (or 9) individually addressable quantum interfaces in a multiplexed atomic quantum memory array and confirm genuine 22 (or 9) partite entanglement, respectively. Experimental entanglement of a record-high number of quantum interfaces makes an important enabling step towards realization of quantum networks, long-distance quantum communication, and multipartite quantum information processing.

description: Disordered thin films close to the superconducting-insulating phase transition (SIT) hold the key to understanding quantum phase transition in strongly correlated materials. The SIT is governed by superconducting quantum fluctuations, which can be revealed for example by tunneling measurements. These experiments detect a spectral gap, accompanied by suppressed coherence peaks that do not fit the BCS prediction. To explain these observations, we consider the effect of finite-range superconducting fluctuations on the density of states, focusing on the insulating side of the SIT. We perform a controlled diagrammatic resummation and derive analytic expressions for the tunneling differential conductance. We find that short-range superconducting fluctuations suppress the coherence peaks, even in the presence of long-range correlations. Our approach offers a quantitative description of existing measurements on disordered thin films and accounts for tunneling spectra with suppressed coherence peaks observed, for example, in the pseudo gap regime of high-temperature superconductors.

description: Speech genres have a significant role in socializing children and adults not only to speak in culturally appropriate ways but also to present desirable identities. We analyze narratives of self-transformation collected in an undergraduate public speaking course in the United States to learn how the acquisition of public speaking as a speech genre contributes to U.S. students’ language socialization. Our study contributes to two traditions of intercultural communication research, one interested in the context-bound, culturally situated character of Anglo-American speech, and another that seeks to explain how local communication resources, including speech genres, travel across cultural boundaries.
Matter Parity Violating Dark Matter Decay in Minimal SO(10), Unification, Vacuum Stability and Verifiable Proton Decay

description: In direct breaking of non-supersymmetric SO(10) to the standard model, we investigate the possibility that dark matter (DM) decaying through its mixing with right-handed neutrino (RH$ν$) produces high energy IceCube neutrinos having type-I seesaw masses. Instead of one universal mixing and one common heavy RH$ν$ mass proposed in a recent standard model extension, we find that underlying quark-lepton symmetry resulting in naturally hierarchical RH$ν$ masses predict a separate mixing with each of them. We determine these mixings from the seesaw prediction of the DM decay rates into the light neutrino flavors. We further show that these mixings originate from Planck-scale assisted spontaneously broken matter parity needed to resolve the associated cosmological domain wall problem. This leads to the prediction of a new LHC accessible matter-parity odd Higgs scalar which also completes vacuum stability in the Higgs potential for its mass $M_{χ_S}\simeq 178$ GeV. Two separate minimal SO(10) models are further noted to predict such dark matter dynamics where a single scalar submultiplet from ${126}^{\dagger}_H$ or ${210}_H$ of intermediate mass achieves precision gauge coupling unification. Despite the presence of two large Higgs representations and the fermionic dark matter host, ${45}_F$, experimentally accessible proton lifetimes are also predicted with reduced uncertainties.
