description: The angular correlation of the electrons emitted in the neutrinoless double beta decay ($0\nu2β$) is presented using a general Lorentz invariant effective Lagrangian for the leptonic and hadronic charged weak currents. We show that the coefficient $K$ in the angular correlation $dΓ/d\cos θ\propto (1-K\cos θ)$ is essentially independent of the nuclear matrix element models and present its numerical values for the five nuclei of interest ($^{76}{Ge}$, $^{82}{Se}$, $^{100}{Mo}$, $^{130}{Te}$, and $^{136}{Xe}$), assuming that the $0\nu2β$-decays in these nuclei are induced solely by a light Majorana neutrino, $ν_M$. This coefficient varies between $K=0.81$ (for the $^{76}{Ge}$ nucleus) and $K=0.88$ (for the $^{82}{Se}$ and $^{100}{Mo}$ nuclei), calculated taking into account the effects from the nucleon recoil, the $S$ and $P$-waves for the outgoing electrons and the electron mass. Deviation of $K$ from its values derived here would indicate the presence of New Physics (NP) in addition to a light Majorana neutrino, and we work out the angular coefficients in several $ν_M + {NP}$ scenarios for the $^{76}{Ge}$ nucleus. As an illustration of the correlations among the $0\nu2β$ observables (half-life $T_{1/2}$, the coefficient $K$, and the effective Majorana neutrino mass $|< m>|$) and the parameters of the underlying NP model, we analyze the left-right symmetric models, taking into account current phenomenological bounds on the right-handed $W_R$-boson mass and the left-right mixing parameter $ζ$.

description: The paper develops a theory of spectral boundary value problems from the perspective of general theory of linear operators in Hilbert spaces. An abstract form of spectral boundary value problem with generalized boundary conditions is suggested and results on its solvability complemented by representations of weak and strong solutions are obtained. Existence of a closed linear operator defined by a given boundary condition and description of its domain are studied in detail. These questions are addressed on the basis of Krein's resolvent formula derived from the explicit representations of solutions also obtained here. Usual resolvent identities for two operators associated with two different boundary conditions are written in terms of the so called M-function. Abstract considerations are complemented by illustrative examples taken from the theory of partial differential operators. Other applications to boundary value problems of analysis and mathematical physics are outlined. (Initial version title "Spectral Boundary Value Problems and their Linear Operators", 2009)

description: The constrained Dirichlet boundary value problem $\ddot x=f(t,x)$, $x(0)=x(T)$, is studied in billiard spaces, where impacts occur in boundary points. Therefore we develop the research on impulsive Dirichlet problems with state-dependent impulses. Inspiring simple examples lead to an approach enabling to obtain both the existence and multiplicity results in one dimensional billiards. Several observations concerning the multidimensional case are also given.

description: The feeding ecology of the black sea bass, Centropristis striata, associated with artificial reefs shows seasonal and size-related changes. Monthly collections totaling 520 black sea bass taken from an artificial reef near the Chesapeake Light Tower, Virginia, between August 1975 and May 1976, were analyzed for food habits as revealed by number, volume, frequency of occurrence and a modified Index of Relative Importance.

The black sea bass feeds on the artificial reef as well as the adjacent areas. When food was abundant on the reef, food items from the reef and the surrounding area were consumed. Upon depletion of the food resource on the reef, the black sea bass resorted to feeding primarily from the areas adjacent to the artificial reef. The four overall predominant foods were Ensis directus (IRI'=910), Pagurus spp. (IRI'=7299), Cancer irroratus (IRI'=601) and Mytilus edulis (IRI'=332). The feeding ecology of the black sea bass on the artificial reef suggests that they are attracted to the reef primarily because of the shelter that the reef affords.

description: CLIP4Clip model transferred from the CLIP has been the de-factor standard to solve the video clip retrieval task from frame-level input, triggering the surge of CLIP4Clip-based models in the video-text retrieval domain. In this work, we rethink the inherent limitation of widely-used mean pooling operation in the frame features aggregation and investigate the adaptions of excitation and aggregation design for discriminative video representation generation. We present a novel excitationand-aggregation design, including (1) The excitation module is available for capturing non-mutuallyexclusive relationships among frame features and achieving frame-wise features recalibration, and (2) The aggregation module is applied to learn exclusiveness used for frame representations aggregation. Similarly, we employ the cascade of sequential module and aggregation design to generate discriminative video representation in the sequential type. Besides, we adopt the excitation design in the tight type to obtain representative frame features for multi-modal interaction. The proposed modules are evaluated on three benchmark datasets of MSR-VTT, ActivityNet and DiDeMo, achieving MSR-VTT (43.9 R@1), ActivityNet (44.1 R@1) and DiDeMo (31.0 R@1). They outperform the CLIP4Clip results by +1.2% (+0.5%), +4.5% (+1.9%) and +9.5% (+2.7%) relative (absolute) improvements, demonstrating the superiority of our proposed excitation and aggregation designs. We hope our work will serve as an alternative for frame representations aggregation and facilitate future research.

description: The paper reports on finding the effect of a strong change in the microwave losses in an HTS-based coplanar waveguide (CPW) at certain values of the input power Pin and direct current Idc. CPW on the basis of 150 nm thick YBa2Cu3O7-δ epitaxial film on a single crystal MgO substrate was studied experimentally. A sharp and reversible transition of the CPW into a strongly dissipative state at the certain meanings of Pin and Idc depending on temperature was observed. Apparently the effect can be explained by self-heating of HTS structure caused by magnetic flux flow under the joint influence of MW and DC.

description: ABSTRACT—Passive Optical Networks (PON) technology
brings an evolution in the industry of Telecommunication for the
provisioning of High Speed Internet (HSI) and Triple Play
bundled Services that includes Voice, Data, and Video Streaming
throughout the world. In Pakistan most of the service providers
are offering broadband services on traditional copper OSP
(Outside Plant) network since 2000. Demand for the high speed
internet and broadband is increasing rapidly, it is desired with
great need to migrate from traditional copper based OSP network
to PON – FTTx (Fiber To The x) infrastructure. Considering the
geographical requirements in Pakistan a scalable fiber network is
required which can be optimized as per the user’s requirements
and demands with high speed bandwidth efficiency, involving the
minimum losses and with ideal capital expenditure (CAPEX). In
this work a platform for migration from copper to fiber access
network with a scalable and optimized PON – FTTx
infrastructure in green field and dry field areas of Pakistan have
been proposed using Geographic Information system (GIS). In
any developing country like Pakistan having the same cultural
and geographical topology, this platform can be used to migrate
from copper to fiber access network to provide the PON based
telecom services. The developed platform for migration from
copper to PON based fiber has been studied, planned, and then
simulated on a selected geographical area of Pakistan with
physical execution that showed better and efficient results with
reduction in capital and operational expenditures. A factual plan
without ambiguities assists the operators of Pakistan to
analyze/forecast bandwidth requirements of an area, optimized
network planning along with the in time and efficient
deployment.

description: The non-holonomic deformation of the nonlinear Schrödinger equation, uniquely obtained from both the Lax pair and Kupershmidt's bi-Hamiltonian [Phys. Lett. A 372, 2634 (2008)] approaches, is compared with the quasi-integrable deformation of the same system [Ferreira et. al. JHEP 2012, 103 (2012)]. It is found that these two deformations can locally coincide only when the phase of the corresponding solution is discontinuous in space, following a definite phase-modulus coupling of the non-holonomic inhomogeneity function. These two deformations are further found to be not gauge-equivalent in general, following the Lax formalism of the nonlinear Schrödinger equation. However, asymptotically they converge for localized solutions as expected. Similar conditional correspondence of nonholonomic deformation with a non-integrable deformation, namely, due to local scaling of the amplitude of the nonlinear Schrödinger equation is further obtained.

description: Poster presented at 5th European Conference on Schizophrenia Research (ECSR 2015, 24-26 September, Berlin)

 Objective
To determine whether there is significant correlation between the severity of symptoms at admission and treatment dose at discharge in first episode psychosis (FEP) inpatients. The study emerge from a perception in our clinical practice: treatment dose is somehow driven in different ways by different psychopathological clusters.
Methods
Observational study of a pragmatic sample of 21 patients over 18 years of both sexes admitted in an inpatient ward with FEP diagnosis at discharge (schizophrenia spectrum disorders). The severity of symptoms was assessed with the Brief Psychiatric Rating Scale (BPRS) at admission and neuroleptic treatment dose at the discharge was calculated in chlorpromazine equivalents. The data was normally distributed as assessed using the Kolmogorov-Smirnov test. The analysis of the correlation between BPRS total score, subscales and neuroleptic dose at discharge was made using the Pearson correlation coefficient and p-value for a significance level at p<0.05.
Results
There is a statistical significant correlation between the total BPRS score and antipsychotic dose (r=0.60, p=0.004). Among symptom subdomains, the activation subscale displays better Pearson correlation (r= 0.59, p=0.004).
Conclusion
A statistical significant association between severity of symptoms at admission and antipsychotic dose is observed in our clinical practice with no scientific evidence to support this attitude. There is consensus on the need to initiate antipsychotic treatment with the lower approved doses, especially in FEP, regardless of clinical severity at admission. The available evidence is limited at the moment. Future studies under controlled conditions would be needed to advance in the knowledge of the relationship that this research suggests.
Symptoms severity at admission is related to insight at discharge in first episode of psychosis.

 Objective To determine whether there is significant correlation between the severity of symptoms and insight in first episode psychosis (FEP) inpatients. The study emerge from a perception in our clinical practice: different psychopathological clusters diverge in the strength they are related to insight. Method Observational study of a pragmatic sample of 21 patients over 18 years of both sexes admitted to an inpatient ward with FEP diagnosis at discharge (schizophrenia spectrum disorders). The severity of symptoms was assessed with the Brief Psychiatric Rating Scale (BPRS) at admission and discharge. Patient insight was assessed with the Scale to assess Unawareness of Mental Disorder (SUM-D) at discharge. The data was normally distributed as assessed using the Kolmogorov-Smirnov test. The analysis of the correlation between BPRS total score, subscales and neuroleptic dose at discharge was made using the Pearson correlation coefficient and p-value for a significance level at p<0.05. Results There is a statistical significant correlation between the total BPRS score at admission and SUMD total score at discharge of r = 0.55 (p = 0.009). Among symptom subdomains, the negative subscale score at admission displays a stronger correlation (r=0.63, p=0.002). Moreover, there is also a statistical significant correlation between the total BPRS score at discharge and SUMD total score of r = 0.68 (p = 0.008) as well as in its negative subscale (r = 0.62, p = 0.002). Conclusions A statistical significant association between the overall severity of symptoms and insight is observed as it was to be expected. In this respect, negative symptomatology and cognitive impairment appear to have a strong relationship with the awareness of illness. These findings reinforce previous evidence in favour of the relationship between insight and severity of symptoms in psychosis and contribute to support this hypothesis in FEP population.

description: We generalize the Thomas-Fermi approach to galaxy structure to include self-consistently and non-linearly central supermassive black holes. This approach naturally incorporates the quantum pressure of the warm dark matter (WDM) particles and shows its full powerful and clearness in the presence of supermassive black holes (SPMHs). We find the main galaxy and central black hole magnitudes: halo radius r_h , halo mass M_h, black hole mass M_BH, velocity dispersion, phase space density, with their realistic astrophysical values, masses and sizes over a wide galaxy range. The SMBH masses arise naturally in this framework. Our extensive numerical calculations and detailed analytic resolution show that with SMBH's, both WDM regimes: classical (Boltzmann dilute) and quantum (compact) do necessarily co-exist in any galaxy: from the smaller and compact galaxies to the largest ones. The transition from the quantum to the classical region occurs precisely at the same point r_A where the chemical potential vanishes. A novel halo structure with three regions shows up: A small quantum compact core of radius r_A around the SMBH, followed by a less compact region till the BH influence radius r_i, and then for r> r_i the known halo galaxy shows up with its astrophysical size. Three representative families of galaxy plus central SMBH solutions are found and analyzed:small, medium and large galaxies having SMBH masses of 10^5, 10^7 and 10^9 M_sun respectively. A minimum galaxy size and mass ~ 10^7 M_sun larger than the one without SMBH is found. Small galaxies in the range 10^4 M_sun < M_h < 10^7 M_sun cannot harbor central SMBHs. We find novel scaling M_BH - r_h - M_h relations. The galaxy equation of state is derived: The pressure P(r) takes huge values in the SMBH vecinity and then sharply decreases entering the classical region following a local perfect gas behaviour.(Abridged)

description: We have studied two interchange layer systems, (i) free standing partly hydrogenated graphene (graphone), and (ii) graphone on the Nickel (111) surface, to assess various density functional theory based computational schemes incorporating van der Waals forces. The various van der Waals methods have been employed ranging from the semiempirical force-field-like correction of Grimme, through non-local van der Waals density functionals, up to the functionals involving exact exchange and the random phase approximation for the correlation. Generally, all computational schemes lead to a similar qualitative picture of hydrogen layer physisorption and chemisorption to graphene. The largest discrepancies between the approaches emerge for the energetics of the investigated systems. Our studies shed light on the physical mechanisms of graphene hydrogenation both in vacuum and in the proximity of metallic surface. In particular, it is revealed that the adsorption of hydrogen atoms affects the nature of the bonding between graphene and the Ni(111) surface, from the weak to strong semi-covalent bonding. On the other hand, it turns out that the adsorption of hydrogen layer to graphene is stronger in the presence of the metallic surface.

description: We present some new relations between the Cauchy-Riemann operator on the real Clifford algebra $\mathbb R_n$ of signature $(0,n)$ and slice-regular functions on $\mathbb R_n$. The class of slice-regular functions, which comprises all polynomials with coefficients on one side, is the base of a recent function theory in several hypercomplex settings, including quaternions and Clifford algebras. In this paper we present formulas, relating the Cauchy-Riemann operator, the spherical Dirac operator, the differential operator characterizing slice regularity, and the {spherical derivative} of a slice function. The computation of the Laplacian of the spherical derivative of a slice regular function gives a result which implies, in particular, the Fueter-Sce Theorem. In the two four-dimensional cases represented by the paravectors of $\mathbb R_3$ and by the space of quaternions, these results are related to zonal harmonics on the three-dimensional sphere and to the Poisson kernel of the unit ball of $\mathbb R^4$.

description: Field experiments were conducted in two year to find out the optimum seeding rate (100, 200, 300 and 400 seeds
m-2) for both bread wheat Giza 168 (Triticum aestivum L.) and durum wheat Sohag 3 (Triticum turgidum L. ssp.
durum) cultivars grown on a sandy loam-soil at Qena in Upper Egypt. The experiment was laid out Randomized
Complete Block Design (RCBD) with split plot arrangement keeping cultivars (C) in main plots and seeding rate
(SR) in sub plots having three replications. Grain yield and its components and grain protein concentration were
measured. Grain yield and its components exhibited a significant response to seeding rate and cultivar
differences. Significant interaction effects between seeding rate and cultivar were detected in both seasons on
yield, selected yield components, and harvest index. But, weight of kernels per spike was not affected by seeding
rate or the seeding rate x cultivar interaction. The highest grain and straw yields as well as harvest index were
recorded for C1SR3 (Giza 168 cv and seeding 300 seeds m-2), while the lowest values were found for C2SR1
(Sohag 3 cv and seeding 100 seeds m-2). There was no significant response to seeding rate in grain protein
concentration. Grains of Sohag 3 (durum wheat) were significantly higher in their protein concentration than
grains of Giza 168 (bread wheat). Crop production functions with respect to seeding rates, determined for grain
yield and yield components enable the results of this study to be extrapolated to other agro-climatic conditions
similar to those in Qena.
Wages, Competition, and the Decline of Union Membership in the US Manufacturing Industry
Creators: name: Aksman, Simona
Publisher: name: figshare
Year: 2015
Subjects: Economics

description: This paper examines the empirical application of the hypothesis that union membership has declined in the US manufacturing industry due to an increasingly competitive environment among firms, despite the fact that union wages have remained higher than nonunion wages. I construct an industry-level model for union membership as well as union wages that has competitive indicators, including inward foreign direct investment, the capital-to-labor ratio, terms of trade, and a ratio of export to import trade volume. I combine the theory of union-firm negotiations and the findings of my empirical study to make the argument that union wage increases drive union membership downwards through competition. As the manufacturing industry faces increasing competition from imports as well as capital’s replacement of labor, firm profits diminish, and the ultimate result is that unions have declining membership. The key finding of my paper is that the underlying cause of the union membership decline is an increasing union wage, which triggers competitive forces to drive down union membership.

description: In this study, we investigate the advantages of non-classical pointer states in the generalized modular value scheme. We consider a typical von Neumann measurement with a discrete quantum pointer, where the pointer is a projection operator onto one of the states of the basis of the pointer Hilbert space. We separately calculate the conditional probabilities, Q_{M} factors, and signal-to-noise ratios of quadrature operators of coherent, coherent squeezed, and Schrödinger cat pointer states and find that the non-classical pointer states can increase the negativity of the field and precision of measurement compared with semi-classical states in generalized measurement problems characterized by the modular value.

description: The notion of typicality in statistical mechanics is essential to characterize a macroscopic system. An overwhelming majority of the pure state looks almost identical if we neglect macroscopic non-local correlations, suggesting that thermal equilibrium is the collection of the typical properties. Quantum entanglement, which characterizes a non-local correlation, also has a typical behavior in equilibrium systems. However, it remains elusive whether there is a typical behavior of entanglement in dynamical non-equilibrium systems. To investigate the typicality, we consider a situation where a system in a pure state starts to share entanglement with its environment system due to the interaction between them. Assuming the initial state is randomly chosen from an ensemble of pure states, a criteria for the typicality of the Rényi entropies is presented. In addition, it is analytically proven that the second Rényi entropy has a typical behavior in two cases. The first one is an energy dissipation process in a multiple-qubit system which is initially in a random pure state in an energy shell. Since the typical behavior is qualitatively the same as the prediction of the Page curve conjecture, it gives the first proof of the Page curve conjecture in a dynamical process. In the second case, the typicality is proven for any dynamics described by a multiple-product of a single-qudit channel when the system is initially in a pure state randomly chosen from the whole Hilbert space. This result shows that entanglement typicality is not a specific feature of energy dissipating processes.

description: We prove that independent families of permutation invariant random matrices are asymptotically free over the diagonal, both in probability and in expectation, under a uniform boundedness assumption on the operator norm. We can relax the operator norm assumption to an estimate on sums associated to graphs of matrices, further extending the range of applications (for example, to Wigner matrices with exploding moments and so the sparse regime of the Erdős-Rényi model). The result still holds even if the matrices are multiplied entrywise by bounded random variables (for example, as in the case of matrices with a variance profile and percolation models).

This article considers all kinds of repairs. First, it discusses behavioral repair where test suites, contracts, models, and crashing inputs are taken as oracle. Second, it discusses state repair, also known as runtime repair or runtime recovery, with techniques such as checkpoint and restart, reconfiguration, and invariant restoration. The uniqueness of this article is that it spans the research communities that contribute to this body of knowledge: software engineering, dependability, operating systems, programming languages, and security. It provides a novel and structured overview of the diversity of bug oracles and repair operators used in the literature.

Rapid phase calibration and increased efficiency of a spatial light modulator using novel phase masks and an iterative algorithm

description: We develop an improved phase calibration method of a reflective spatial light modulator (SLM) using interferometry by employing novel phase masks. We generate the optimised phase masks by using Iterative Fourier Transform Algorithm (IFTA) and demonstrate that they perform with 18$\%$ better efficiency over global linear corrections in the look-up table (LUT). In addition, we also implement global linear corrections in the LUT and correspondingly modify the phase encoding of blazed gratings to improve the efficiency of our phase-limited SLM. In the process, we definitively determine the actual maximum phase throw of our SLM which provides a recipe for users to verify supplier specifications.Besides obtaining array of 1D/2D spots having high uniformity (~90$\%$) using IFTA, our result exemplifies the use of iterative algorithms for improving efficiency of phase limited SLMs. Finally, our method enables threefold faster phase measurements, and to the best of our knowledge, is the first endeavour directed towards enabling rapid phase characterisation of an SLM using interferometric measurements and can have very useful applications in settings which often require faster phase calibrations.

description: Many tasks require precise synchronization with external sensory stimuli, such as driving a car. This study investigates whether combined visual-tactile information provides additional benefits to movement synchrony over separate visual and tactile stimuli and explores the relationship with the temporal binding window for multisensory integration. In Experiment 1, participants completed a sensorimotor synchronization task to examine movement variability and a simultaneity judgment task to measure the temporal binding window. Results showed similar synchronization variability between visual-tactile and tactile-only stimuli, but significantly lower than visual only. In Experiment 2, participants completed a visual-tactile sensorimotor synchronization task with cross-modal stimuli presented inside (stimulus onset asynchrony 80 ms) and outside (stimulus-onset asynchrony 400 ms) the temporal binding window to examine temporal accuracy of movement execution. Participants synchronized their movement with the first stimulus in the cross-modal pair, either the visual or tactile stimulus. Results showed significantly greater temporal accuracy when only one stimulus was presented inside the window and the second stimulus was outside the window than when both stimuli were presented inside the window, with movement execution being more accurate when attending to the tactile stimulus. Overall, these findings indicate there may be a modality-specific benefit to sensorimotor synchronization performance, such that tactile cues are weighted more strongly than visual information as tactile information is more intrinsically linked to motor timing than visual information. Further, our findings indicate that the visual-tactile temporal binding window is related to the temporal accuracy of movement execution.

description: We study dynamic network flows and introduce a notion of instantaneous dynamic equilibrium (IDE) requiring that for any positive inflow into an edge, this edge must lie on a currently shortest path towards the respective sink. We measure current shortest path length by current waiting times in queues plus physical travel times. As our main results, we show: 1. existence and constructive computation of IDE flows for single-source single-sink networks assuming constant network inflow rates, 2. finite termination of IDE flows for multi-source single-sink networks assuming bounded and finitely lasting inflow rates, 3. the existence of IDE flows for multi-source multi-sink instances assuming general measurable network inflow rates, 4. the existence of a complex single-source multi-sink instance in which any IDE flow is caught in cycles and flow remains forever in the network.

description: Extraordinary gauge mediation extension of deflected AMSB scenarios can be interesting because it can accommodate together the deflection in the Kahler potential and the superpotential. We revisit the EGM scenario and derive the analytical expressions for soft SUSY breaking parameters in EGM and EGM extension of deflected AMSB scenarios with wavefunction renormalization approach, especially the case with vanishing gauge beta-function at an intermediate energy scale. The Landau pole and proton decay constraints are also discussed.

description: In this paper, we study doubly reflected Backward Stochastic Differential Equations defined on probability spaces equipped with filtration satisfying only the usual assumptions of right continuity and completeness in the case where the barriers L and U don't satisfy any regularity assumption (without right continuity). We suppose that the barriers L and U and their left limits are completely separated and we show existence and uniqueness of the solution.

description: We introduce and analyze a new geometric structure on topological surfaces generalizing the complex structure. To define this so called higher complex structure we use the punctual Hilbert scheme of the plane. The moduli space of higher complex structures is defined and is shown to be a generalization of the classical Teichmüller space. We give arguments for the conjectural isomorphism between the moduli space of higher complex structures and Hitchin's component.

description: We prove a Jensen formula for slice-regular functions of one quaternionic variable. The formula relates the value of the function and of its first two derivatives at a point with its integral mean on a three dimensional sphere centred at that point and with the disposition of its zeros. The formula can be extended to semiregular slice functions.

description: The purpose of this paper is to present several new, sometimes surprising, results concerning a class of hyperholomorphic functions over quaternions, the so-called slice regular functions. The concept of slice regular function is a generalization of the one of holomorphic function in one complex variable. The results we present here show that such a generalization is multifaceted and highly non-trivial. We study the behavior of the Jacobian $J_f$ of a slice regular function $f$ proving in particular that $\det(J_f)\geq0$, i.e. $f$ is orientation-preserving. We give a complete characterization of the fibers of $f$ making use of a new notion we introduce here, the one of wing of $f$. We investigate the singular set $N_f$ of $f$, i.e. the set in which $J_f$ is singular. The singular set $N_f$ turns out to be equal to the branch set of $f$, i.e. the set of points $y$ such that $f$ is not a homeomorphism locally at $y$. We establish the quasi-openness properties of $f$. As a consequence we deduce the validity of the Maximum Modulus Principle for $f$ in its full generality. Our results are sharp as we show by explicit examples.

description: We introduce and study the notion of contact dual pair adopting a line bundle approach to contact and Jacobi geometry. A contact dual pair is a pair of Jacobi morphisms defined on the same contact manifold and satisfying a certain orthogonality condition. Contact groupoids and contact reduction are the main sources of examples. Among other properties, we prove the Characteristic Leaf Correspondence Theorem for contact dual pairs which parallels the analogous result of Weinstein for symplectic dual pairs.

description: We consider the minimum vertex cover problem having applications in e.g. biochemistry and network security. Quantum annealers can find the optimum solution of such NP-hard problems, given they can be embedded on the hardware. This is often infeasible due to limitations of the hardware connectivity structure. This paper presents a decomposition algorithm for the minimum vertex cover problem: The algorithm recursively divides an arbitrary problem until the generated subproblems can be embedded and solved on the annealer. To speed up the decomposition, we propose several pruning and reduction techniques. The performance of our algorithm is assessed in a simulation study.

description: Let $ R $ be a regular local ring with maximal ideal $ \mathfrak{m} $. We consider elements $ f \in R $ such that their Newton polyhedron has a loose edge. We show that if the symbolic restriction of $f$ to such an edge is a product of two coprime polynomials, then $f$ factorizes in the $ \mathfrak{m} $-adic completion.

description: In this paper, we report on the results of features in the discovered effect of a strong change in the microwave losses (quenching) in HTS-based coplanar waveguide (CPW) at certain values of the input power $P_{in}$ and direct current (DC) $I_{dc}$. Two waveguides were studied: CPW-150 and CPW-75, fabricated of epitaxial 150 nm and 75 nm YBCO films. The insertion loss of CPW, $IL = 10 lg (P_{out} / P_{in})$, was measured versus both the operating temperature and the bias DC current $I_{dc}$ when a fixed level of the input X-band pulsed MW signal $P_{in}$ was applied. Here $P_{out}$ is the power measured at the CPW output. A pulse duration $τ_i$ was 5 $μs$ with pulse repetition period T = 40 $μs$. Experiments showed a noticeable difference in specific values of $I^*= I_{dc}$ corresponding to the $P_{in}$ dependent quenching phenomenon in CPW-150 and CPW-75. With a weak input signal the difference in behavior of CPWs is anticipated, i.e., quenching occurs at a lower current for thinner film. For $P_{in}>1W$ the situation is opposite, i.e., quenching for CPW-150 takes place at a lower $I^*$. This is explained by stronger microwave heating of CPW-150.
